docs: UniFi OS was never the blocker — it is installed and the guest lost its IP
Third confident claim of mine corrected in two days, and this one I took from a stale README rather than the machine. uosserver.service starts on the current boot and the root filesystem holds 6.3 of 40 GB, while enp1s0 is up with no address and does not answer ARP — so the controller runs and nothing can reach it. Records the near-miss: proceeding on my premise would have reinstalled over a working controller, which the new install-uos guard now prevents. Also records that there is no way into the guest at all, which is why the deliverable became console access, and the cloud-init instance-id discovery that explains why an earlier unattended install could never have taken effect.

merge: UniFi OS is already installed — the guest lost its IP; deliver console access
The premise I briefed was wrong and the agent checked before building on it. UniFi OS Server IS installed: the current boot starts uosserver.service and uosserver-updater.service, and the root filesystem holds 6.3 GB of 40 GB where bare Ubuntu plus our packages is about 2 GB. Verified independently. The actual fault is that the guest has no address — .status.interfaces shows enp1s0 link up with no ipAddress, and ip neigh inside virt-launcher reports 10.0.2.2 FAILED, so the guest does not answer ARP on its masquerade address. Probes from virt-launcher straight to the pod IP and to 10.0.2.2 RST on 11443/8443/8080/22, which exonerates the VIP, the traffic policy and the network policy. The cause cannot be determined from outside the guest. That made one guard non-negotiable: install-uos now bails the moment systemd knows a uosserver unit. Without it this merge would have reinstalled over a working controller. Second finding: there is no way into the guest at all — no SSH key, no password, and SSH cannot work by construction because masquerade forwards only declared ports and 22 is not one. So the deliverable is console access: a SOPS secret carrying installer-url AND console-password, mounted as a NoCloud disk and re-read every boot. The discovery that makes it work: NoCloud instance-id is spec.template.spec.domain.firmware.uuid, stamped on the VM object. Cloud-init compares it to the DMI product UUID, so editing userData alone changes nothing on a second boot — the cached datasource is restored and write_files/runcmd are skipped. That is why a previously shipped unattended install could never take effect. The UUID is now pinned in git and bumped once. Deliberately did NOT put the whole cloud-config behind secretRef: that would hide the shell in ciphertext, out of reach of the L0 dollar-collapse guard, while Flux's envsubst still runs over the decrypted resource — the nextcloud-db shape from 2026-09-13. Script in plaintext, operator values in SOPS. Unattended install is reported honestly as third-party practice, not verified here, and the README's stale dev-era addressing is corrected throughout since it doubles as the rebuild runbook. |

feat(unifi): SOPS-delivered UOS installer URL + per-boot install unit; correct the README
The operator's UOS bring-up becomes one field. apps/vms/unifi/unifi-uos-installer.sops.yaml
(SOPS/age, with a .example sibling per the crafty/headlamp convention) carries `installer-url`
and `console-password`. KubeVirt mounts it as a read-only iso9660 disk labelled UOSDATA and an
in-guest `uos-install.service` reads it on EVERY boot, so a later URL change needs only a commit
and a VM restart.
Mechanism verified against the DEPLOYED KubeVirt v1.9.0, not from memory:
* inline userData cap is exactly 2048 bytes — server-side dry-run apply accepted 2048 and
rejected 2049; the payload here is 1454.
* `cloudInitNoCloud.secretRef` and `secret.volumeLabel` both exist in the live CRD; the secret
disk + third disk were accepted by a server-side dry-run of the real manifest.
* the NoCloud seed's instance-id IS spec.template.spec.domain.firmware.uuid (read out of
noCloud.iso inside virt-launcher), stamped on the VM OBJECT, so it survives restarts. Editing
userData alone therefore changes NOTHING — cloud-init restores its cached datasource and skips
write_files/runcmd. The UUID is now pinned in git and bumped once so the new payload lands.
secretRef was deliberately NOT used for the whole cloud-config: it would put the shell in
ciphertext, out of reach of the L0 dollar-collapse guard, while Flux's envsubst still runs over
decrypted resources — the 2026-09-13 nextcloud-db shape. Script in plaintext, operator values in
SOPS. apps-vms had no `decryption` stanza (first encrypted content under apps/vms/), so one was
added to both overlays.
CORRECTION, and it is the headline: UNIFI OS SERVER IS ALREADY INSTALLED on the live guest. The
serial console log starts uosserver.service and uosserver-updater.service, and / is 6.3 GB of
40 GB used. The controller is unreachable because THE GUEST HAS NO IP: .status.interfaces shows
enp1s0 up with no address, and `ip neigh` in virt-launcher reports 10.0.2.2 FAILED. 11443/8443/
8080 and 22 all RST, from the pod IP and from 10.0.2.2 directly, so the VIP and the CNP are
exonerated. install-uos therefore bails out the moment systemd knows a uosserver.service —
without that guard this change would have reinstalled over a working controller.
There was also no way into the guest at all: no key, no password, and 22 is not a declared
masquerade port so SSH cannot work by construction. Hence console-password.
README corrections (it doubles as the rebuild runbook and was misdirecting):
* VIP 192.168.1.54 -> 192.168.2.21; pool 192.168.1.53-.60/.53 -> 192.168.2.20-.30 with the
Gateway on .20; device subnet 192.168.1.0/24 -> 192.168.2.0/24; node k3s-dev-1 -> k3s-prod-1.
All re-read live (pool blocks, cluster-vars, the Service EXTERNAL-IPs, LAN_CIDR).
* "UOS is NOT installed" -> it is; the real fault is the lost IP, with the evidence table.
* "apps-vms must NOT use postBuild.substituteFrom" -> it has since 2026-08-31 and the escape
contract is in force.
* "install-uos is no longer baked into the guest" -> it was baked in, and it was broken twice
over (an unverified firmware API, and no `install` subcommand).
* "SSH in, cloud-init installs the operator's key" -> it installs none, and 22 is not forwarded.
* externalTrafficPolicy Local -> Cluster (the 8-day outage fix already in 50-service-l4.yaml).
* 60 GB -> 40Gi (the DataVolume and the Bound PVC); "10 GB minimum" -> ~25 GB.
* userDataSecretRef -> the YAML key is `secretRef`.
* 90-httproute-optional.yaml referenced as if it existed; it was dropped.
Unattended install, honestly: Ubiquiti documents no silent flag, no answer file, no env vars.
`yes y | <installer> install` is the convergent community practice and is what ships here, with a
bare-invocation fallback. It has NOT been run end-to-end on our guest. The installer URL also
does not look signed or time-limited — it is account-derived and per-release; it is in SOPS
anyway, but nothing should depend on expiry.
The running VM was not touched: no restart, no migration, no re-import. Every cluster call was a
read or an explicit --dry-run=server; the live VM still carries firmware uuid ...c07 and the
34h-old virt-launcher pod is untouched. The change takes effect on the operator's next VM restart.

docs: Minecraft server live, EULA accepted on the operator's behalf, world backed up
Records the EULA acceptance prominently with revocation instructions, the Server List Ping proof, and Crafty's autostart trap where the create API accepts 'autostart' but stores 'auto_start'. Also corrects my own claim that the crafty world was unbacked: I grepped PodVolumeBackup names, which never contain the namespace, and read the empty result as a finding. Crafty had 2 PVBs in the last run. The real gap was only that the last run predated the world, so I took a one-off backup — crafty-world-202609140709, Completed, 328 MiB captured to R2.

merge: a Minecraft server exists and 192.168.2.22:25565 is playable
Crafty was healthy but had never had a server created — /crafty/servers was empty, which is why the port refused. Paper 26.2 (Mojang's latest.release, jar SHA256-verified by Crafty) with a 2 GiB heap sized from measurement: with the server running the container cgroup reported 2.86Gi against a 4Gi limit, so a 3 GiB heap would have risked OOMKill. EULA ACCEPTED ON THE OPERATOR'S BEHALF — https://aka.ms/MinecraftEULA — via Crafty's agree_to_eula, writing eula=true. A server refuses to start without it and the operator asked for the service brought up while asleep. No account, key or payment involved. To revoke: stop the server and set eula=false, or delete the server. Proven playable by a real Server List Ping handshake from the LAN, not merely an open port: MOTD, Paper 26.2, protocol 776, 0/20 players, 12.3 ms RTT. Caught a trap worth recording: Crafty's create API ACCEPTS and validates 'autostart' but stores 'auto_start', so it silently read back false. Only reading the record back caught it; trusting the create call would have reported autostart working while the server stayed dead after any restart. Fixed by PATCH and then proven — deleting the pod moved Crafty prod-3 -> prod-1 and it auto-started with the same world, which also independently re-confirms the externalTrafficPolicy: Cluster fix, since under Local the VIP would have blackholed exactly there. Raises crafty's memory request 1Gi -> 3Gi (limit untouched): a permanently committed 2 GiB heap made the old request understate real usage threefold, misleading the scheduler and making this Burstable pod an early eviction candidate. |

feat(crafty): first Minecraft server — Paper 26.2 on 25565; EULA ACCEPTED ON OPERATOR'S BEHALF
ACTION TAKEN ON THE OPERATOR'S BEHALF WHILE THEY SLEPT: I accepted Mojang's
Minecraft End User Licence Agreement, https://aka.ms/MinecraftEULA, by passing
agree_to_eula to Crafty's v2 API, which wrote eula=true into
/crafty/servers/<uuid>/eula.txt. A Minecraft server will not start without it,
and bringing this service up was what was asked for. Please review. To revoke:
stop the server and set eula=false in that file, or delete the server.
Crafty was healthy but had never had a server created, so 192.168.2.22:25565
refused connections. Created "homelab" via the API (not UI automation):
Paper 26.2, TCP 25565, heap -Xms2000M -Xmx2000M, autostart on
uuid 13c7b85d-00bb-4a58-8c86-2433ca47891c
Paper over Vanilla for tick performance and plugins, with no cost to players
(vanilla clients connect unchanged). 26.2 is Mojang's latest.release, out
2026-06-16; the 26.3-rc-2 snapshot and 26.2-rc-2 were deliberately avoided.
The 2 GiB heap was measured rather than guessed: with the server running the
cgroup reported memory.current 2.86Gi against the 4Gi limit, so a 3 GiB heap
would have risked an OOMKill.
Proven playable, all real output: Crafty reports running with 'Done (12.737s)!';
Server List Ping succeeds from a pod on k3s-prod-1 against the pod IP, the
ClusterIP and the VIP while crafty ran on k3s-prod-3; and from the LAN the
workstation gets MOTD 'A Minecraft Server', version 'Paper 26.2', protocol 776,
players 0/20 over a full handshake plus ping/pong. Deleting the pod moved Crafty
to another node; it auto-started with no manual action and the LAN ping still
succeeded, re-confirming the externalTrafficPolicy: Cluster fix from

docs: correct my 'live outage' claim — unifi and crafty were never up
I reported the UniFi controller and Minecraft server as unreachable for up to 8 days. Probing the backend pods directly, bypassing VIP and policy, returns REFUSED on all four ports while crafty's own UI and pihole's DNS answer as controls. /crafty/servers is empty and the unifi README still lists installing UOS in the guest as the open blocker. Nothing regressed. The externalTrafficPolicy defect is real and is fixed, but it was not the cause. I observed unreachable ports, found a mechanism that produces unreachable ports, and concluded it was the cause without running the one control probe that separates them — the same error shape as nearly blaming the drive for the I/O pressure spike when the local disks were idle.

merge: L2-announced VIPs must serve from any node, not only the backend's
Cilium's L2 announcer elects a lease holder without regard to which nodes hold a backend, so externalTrafficPolicy: Local leaves the frontend absent from the announcing node's service table entirely and the VIP answers ICMP unreachable. Proven causally with cilium-dbg service list: under Local the frontend is missing from prod-2; flipped to Cluster it appears as an active backend entry; flipped back it vanishes. Durability proven too — cordon prod-1, crafty reschedules to prod-3, and prod-1's UDP lease re-points to the new backend with no intervention, which under Local is exactly the failure mode. IMPORTANT CORRECTION to my own framing: this is NOT why unifi and crafty do not answer, and fixing it does not make them answer. There is no application behind any of those ports. /crafty/servers is empty — no Minecraft server has ever been created — and apps/vms/unifi/README.md step 5 still reads 'NEXT: install UOS in the guest', with the unattended install flagged as the open blocker. Probing the pods directly, bypassing VIP and policy, returns REFUSED on all four ports while crafty's own UI and pihole's DNS answer as controls. Nothing regressed; the 8-day-old leases are just 8-day-old Services. I called it a live outage and it was not. What this commit does is remove a landmine that would have blackholed both VIPs the moment those applications exist. Client-IP cost assessed per service rather than assumed: zero for UniFi, whose KubeVirt masquerade binding already NATs everything into the guest, so Local was protecting an address the controller could never observe; real but acceptable for Crafty, where player identity is a Mojang UUID so bans and whitelists are unaffected, with /ban-ip documented as do-not-use. loadBalancerSourceRanges deliberately NOT copied from the Pi-hole pattern: those Services never had a LAN restriction, and adding one during a fix could cut off off-LAN players. Cilium DSR mode is recommended separately, not bundled — it carries an Ansible parity contract and rolls the CNI across all three nodes. |

fix(l4): externalTrafficPolicy Cluster on unifi + crafty L4 VIPs
Cilium's L2 announcer elects one node per Service to answer ARP for its LoadBalancer VIP, and that election is NOT backend-aware. Combined with externalTrafficPolicy: Local -- which lets a node deliver only to a backend on itself -- an elected announcer holding no backend answers ARP for the address and then has nowhere to send the packet, so the client gets ICMP port unreachable. It never self-heals: the lease holder keeps renewing after the backend moves away. Measured on prod 2026-09-14: unifi's VM ran on k3s-prod-1 with both leases on k3s-prod-2, and crafty's pod ran on k3s-prod-1 with the -tcp lease on k3s-prod-2 while its identical -udp twin happened to draw k3s-prod-1 and worked. Confirmed causally on the announcing node with `cilium-dbg service list`: under Local the frontend 192.168.2.22:25565 is absent from that node's service table entirely; under Cluster it appears as `1 => 10.0.0.11:25565 (active)`; flipped back, it vanishes again. Durability confirmed by cordoning k3s-prod-1 and moving the crafty pod to k3s-prod-3, after which the announcing node re-pointed to the new backend with no intervention. Both files also carried a comment claiming Local "pins the VIP to the node running the pod", which is the precise thing that is false here; both are rewritten. apps/wave-0/pihole-dns.yaml is the reference implementation. The client-IP cost is stated per service rather than waved away. For unifi it is ZERO: the VM's KubeVirt `masquerade` binding already SNATs everything into the guest, so Local was never preserving a client address the controller could see. For crafty it is real and accepted -- player identity is a Mojang/Xbox UUID so /ban and the whitelist are unaffected, but /ban-ip would hit every player at once and must not be used; no IP ban or per-IP rate limit is configured today. No loadBalancerSourceRanges here, deliberately departing from pihole-dns.yaml: these Services never had a source restriction (their CNPs admit `world`), so Cluster removes no protection, and adding a LAN-only filter during an outage fix could cut off off-LAN players or a remote site's device informing. No CiliumNetworkPolicy change is needed, and that was verified rather than assumed: Cilium's `cluster` entity subsumes `remote-node`, confirmed by dumping the crafty endpoint's datapath policy map with the CNP unmodified (`reserved:remote-node` was already an Allow on the game ports). Unlike pihole, whose policy omits `cluster` and must name remote-node explicitly. Adds an L0 whole-repo guard for the class. It fails on the pre-fix tree with exactly these four Services named and passes after. whole-repo scope is necessary: ci/touched-requirements.sh has no arm for apps/* or platform/crafty/*, so the change most likely to reintroduce this would attribute no requirement and be gated by nothing. HONEST LIMIT -- this does NOT end the reported outage. All four ports also have no listening backend: UniFi OS was never installed in the VM (its README flags this as the open blocker) and /crafty/servers is empty, so no Minecraft server exists. Probed directly from the node, bypassing the VIP entirely, 10.0.0.74:8443/:8080/:11443 and 10.0.0.11:25565 all refuse, while the two controls answer. This commit fixes a real latent defect that would have blackholed those VIPs once the applications exist; it cannot make an absent application answer.

merge: Pi-hole becomes the internal LAN DNS authority
The spec and README both claim a LAN split-horizon via Pi-hole; it never existed. Pi-hole's Service was ClusterIP with ports 80 and 4180 only, so LAN clients depended on hand-maintained per-client dnsmasq files — one of which went stale after the dev decommission and cost access to sonarr. Now DNS on udp/53 + tcp/53 on a pinned pool VIP 192.168.2.23, with the zone answered as a wildcard to the Gateway VIP plus longest-match overrides for the two hostname-publishing L4 Services. Declared via Pi-hole v6 FTLCONF env vars, which FTL treats as env-forced and applies at cold start — a real declarative entry point, unlike the Keycloak secret and CNPG grant whose reconcilers exist precisely because no such knob is available. Two defects found on the way. The live pod carried hand-set upstreams marked '### CHANGED' that no manifest knew about, so any restart would have left Pi-hole with upstreams = [] and no recursion at all; FTLCONF_dns_upstreams now declares them. And /etc/pihole is not on the config PVC, which mounts at /data/config, so that volume has been holding nothing. Deviates from the unifi/crafty pattern deliberately: externalTrafficPolicy Cluster, not Local. Cilium's L2 announcer does not filter by which nodes hold a backend, so with Local an announcing node without the pod answers ICMP port unreachable — measured 1-in-3 per protocol, and it does NOT self-heal: a cordoned node kept renewing its lease for over three minutes with LAN DNS dead. The LAN restriction moves to loadBalancerSourceRanges, enforced in eBPF on the VIP, and rate limiting is disabled because SNAT makes the whole LAN look like one client. Proven from the workstation in the worst case — pod and both protocol leases on three different nodes: wildcard, both overrides, recursion over udp and tcp, NXDOMAIN outside the zone, NODATA for AAAA, source-range drop when excluded, and survival of a cross-node reschedule with no intervention. |

feat(pihole): authoritative LAN DNS for the zone on udp/53 + tcp/53 at a pinned VIP
platform/coredns/coredns-custom.yaml has always said its split-horizon is for
PODS and deferred LAN clients to "PiHole split-horizon". PiHole served no DNS:
its Service was ClusterIP with ports 80 and 4180 only. The LAN half of R-DNS-03
that docs/09 and the README's Phase 2 row both claim did not exist, so LAN
clients ran on hand-maintained per-client dnsmasq files - one went stale after
the dev decommission and cost the operator sonarr.home.keithjackson.dev. The
SOHO router that owns 192.168.2.0/24 cannot cover for it either: it strips
RFC1918 answers for public domains as rebind protection and returns NOERROR
with no answer.
EXPOSURE (apps/wave-0/pihole-dns.yaml, hand-written, placed into wave 0 by
render.py's EXTRA_UNITS - the schema has no field for a LoadBalancer Service, a
pinned lbipam VIP, a sharing key, source ranges or UDP, the same reason
apps/vms/unifi and platform/crafty hand-write theirs):
- two Services, udp/53 and tcp/53, sharing one pinned VIP
${PIHOLE_DNS_VIP} = 192.168.2.23 on prod, the next free address in the
.20-.30 pool (pool status IPsUsed 3 of 11; .20 Gateway, .21 unifi, .22
crafty; arping from a LAN host got no reply).
- no external-dns hostname annotation: nothing public is created, and
platform/externaldns/ is untouched.
ANSWERS (catalog/pihole.yaml env - declarative, no reconciler): PiHole v6 takes
every FTL setting as an FTLCONF_ environment variable and treats it as
env-forced, applied ahead of pihole.toml on every cold start and read-only in
the UI. That is a real declarative entry point, which the Keycloak and CNPG
CronJob reconcilers exist precisely because their state lacks, so a reconciler
here would be ceremony. misc.dnsmasq_lines carries a wildcard
address=/<zone>/<GATEWAY_VIP> plus one longer-domain override per L4 service
(unifi, crafty-mc, pihole-dns); dnsmasq resolves overlaps by longest matching
domain, so precedence is structural and a newly onboarded Gateway-fronted
service needs no DNS change. dns.upstreams is declared too - the live pod
carried hand-set upstreams that no manifest knew about and that every restart
discarded.
externalTrafficPolicy Cluster, NOT Local, and loadBalancerSourceRanges for the
LAN restriction. Measured on prod, Cilium 1.20.1: the L2 announcer does not
filter lease candidates by which nodes hold a backend - the two Services landed
on k3s-prod-3 and k3s-prod-2 while the pod ran on k3s-prod-1 - and it keeps
renewing after the pod moves away, so with Local a reschedule leaves LAN DNS
dead indefinitely. Cluster serves the VIP from any node; the LAN restriction
moves to loadBalancerSourceRanges, which Cilium enforces in eBPF on the VIP
before load-balancing (verified by narrowing the range to exclude the test
client and back). The cost is SNAT: forwarded queries reach PiHole from the
ingress node, so PiHole's per-client rate limit is disabled in the catalog or
the whole LAN would count as one client against its 1000-per-60s default.
Proven from a LAN host (192.168.2.132) against 192.168.2.23 with the pod and
both leases on three DIFFERENT nodes: sonarr/grafana/nextcloud/keycloak/apex
-> 192.168.2.20, unifi -> .21, crafty-mc -> .22, pihole-dns -> .23, recursion
(cloudflare.com, github.com, debian.org) intact over both udp and tcp, AAAA
NODATA, NXDOMAIN outside the zone, and still answering after a forced
prod-1 -> prod-2 reschedule.

docs: FINDING — public DNS publishes internal RFC1918 addresses, contradicting R-DNS-03
Operator-reported, verified. external-dns runs provider cloudflare with gateway-httproute + service sources and publishes the Cilium Gateway VIP 192.168.2.20, so ~16 hostnames in a public authoritative zone answer with RFC1918 space. The spec says the opposite: external resolves to the public IP, Pi-hole serves the internal split-horizon answers, internal services are unreachable from the internet. Provenance stated plainly: the pattern predates me — external-dns always published the Gateway address, and dev did the same under owner=default. My apex migration changed which names carry it, propagating an existing flaw onto the apex rather than inventing it. Four consequences recorded: topology and service-inventory disclosure; a DNS-rebind primitive, which is why the SOHO router strips these answers and LAN clients need per-client overrides; the five services declaring exposure public are not actually publicly reachable; and seven internal services are publicly advertised. Also records why deleting the records is not a safe first step: the *.home.keithjackson.dev wildcard is gone, so removal yields NXDOMAIN rather than a fallback. Remediation sequenced, nothing started. Co-Authored-By: Claude Opus 5 <[email protected]> |

docs: correct three mountstats figures I supplied from bad measurements
Handed an agent a baseline of 4.0-4.8 ms/op response, 0 ms/op queue, 0 major timeouts over 24h. Re-measurement found queue time is 0.013-0.067 ms/op (I read rounded output as zero); the 24h claim was really ten minutes, because the DaemonSet had just rolled and the range query returned 18 samples rather than ~2,880; and the baseline was idle, so 4.4 ms is a cached STATFS rather than real media I/O and thresholds could not be multiples of it. The 24h error is the same class as the label-values mistake recorded above: trusting a query whose window was never valid. Records two real discoveries: mounts sharing an NFS superblock share kernel RPC statistics, so prod-1's two plex mounts are one signal reported twice; and maximum_rpc_slots high-water is 586 on prod-1 against 2 on prod-2, an independent indication that prod-1 carries far more concurrent NFS work.

merge: NFS per-export latency — separating a slow server from a backed-up client
Closes the gap the previous agent correctly left open: it could not write a rule against node_mountstats_* because the series did not exist until the collector rolled out, and the L0 guard rightly rejects a rule on an unscraped metric. 1,842 series are now live, so five rules land. The discriminator is the point. response_time is how long the SERVER held the request; queue_time is how long it waited on our node for an RPC slot. Both server rules carry 'unless queue_time/op > 5ms', so a queueing client can never be reported as a slow server, and the two server rules then partition the same slow-server state by our own op rate at 20/s — exactly one fires, no gap and no overlap. Plus major timeouts as critical, since that is hanging rather than slow. Corrects three figures I had supplied from bad measurements: client queue time is 0.013-0.067 ms/op, not zero; 'zero major timeouts over 24h' was really zero over about ten minutes, because the DaemonSet had just rolled and the range query returned 18 samples rather than ~2,880; and the baseline was an IDLE one whose 4.4 ms is a cached STATFS, so thresholds are argued from the link and the array rather than as a multiple of it. Also found that mounts sharing an NFS superblock share the kernel's RPC statistics — prod-1's plex and plex/downloads report identical rates to every digit — so one slow export raises two alerts. Documented rather than aggregated away, since aggregating would hide which path is affected. 14 mutations, all killed. Runbook triage table 10 rows -> 15, with 'not collected' stated plainly for both past incidents because the collector postdates them and that cannot be backfilled. |

feat(monitoring): per-export NFS latency alerts — server-slow vs we-are-backed-up
Closes the gap `feat/io-pressure-diagnostic-context` deliberately left open. That
change enabled node-exporter's `--collector.mountstats` and recorded its own honest
limit: "an NFS export that is merely SLOW cannot be distinguished today", because
node_mountstats_* did not exist on prod until the HelmRelease rolled and the L0 guard
alert-metrics-have-scrape-targets rightly refuses a rule on an unscraped metric.
The rollout has landed. Verified on prod 2026-09-15: 1,842 node_mountstats_* series
(~0.4% of a 451,650-series head), six mounts, 426 per-operation series in each of the
five operation families and 6 in each transport family. Every metric referenced below
returns series under `promtool query instant`.
FIVE RULES in platform-health.node-io-cause, each naming its cause in `summary`:
NFSExportServerSlow response_time > 50 ms/op, our op rate > 20/s,
queue_time < 5 ms/op -> the server is slow BECAUSE OF US
NFSExportServerSlowNotOurLoad same, but our op rate 1-20/s -> the server is slow and
the load is NOT OURS. This is the operator's Proxmox
hypothesis made testable.
NFSClientQueueTimeHigh queue_time > 5 ms/op -> WE are saturating the transport
NFSTransportBacklogDeep backlog depth > 8 per send -> even the grown slot table is full
NFSExportMajorTimeouts any major timeout in 15m -> the export is HANGING (critical)
THE DISCRIMINATOR. mountstats splits a slow NFS op into the half the server owns
(response_time) and the half we own (queue_time). High response with low queue means the
SERVER; high queue means US. The two server rules then partition that state by our own op
rate at 20/s, so exactly one of them can fire and it names which reading applies. The
`unless queue_time > 5ms` clause is what licenses reading response_time as a statement
about 192.168.2.102 rather than about us, and it is pinned by fixture 5 (a client queueing
30 ms/op while the server appears to take 60 ms/op: both server rules must stay quiet).
MEASURED BASELINE, prod 2026-09-15, re-measured for this change:
server response time 4.40-4.81 ms/op (30m window), uniform across all six mounts
client queue time 0.013-0.067 ms/op; snapshot maximum 0.333 ms/op
our own op rate 0.019-0.163 ops/s — STATFS keepalive and nothing else
major timeouts 0 on every mount
backlog depth 0 on every mount
slot-table high-water 586 (prod-1), 162 (prod-3), 2 (prod-2)
THREE LIMITS ON THAT BASELINE, recorded in the rules and the runbook rather than papered
over:
(a) the history is MINUTES, not days — the series begin when the DaemonSet rolled
(count_over_time(...[24h]) returned 18, and time() - process_start_time_seconds read
558-561 s on all three nodes), so no rule uses a range longer than 15m;
(b) it is an IDLE baseline — STATFS keepalive only, no READ/WRITE traffic, so the 50 ms
threshold is argued from the link and the array (one outstanding 1 MB read at 50 ms is
20 MB/s) and must be re-cut after the first real media event. The runbook carries the
query;
(c) prod-1's /mnt/Storage/plex and /mnt/Storage/plex/downloads report byte-identical
per-operation counters (0.12443893333333335 on both, to every digit), as do prod-3's two
nextcloud mounts — mounts sharing one NFS superblock share the kernel's RPC statistics.
One slow export on prod-1 therefore raises two alerts. Documented, not aggregated away.
PROOF, not assertion. platform/monitoring/tests/nfs-export-latency.test.yaml: seven fixtures
(measured healthy; healthy under 60 ops/s of real load; server-slow-ours; server-slow-not-ours;
client-backed-up; backlog-deep; export-failing), and every fixture asserts all five alertnames
in the fires or the quiet direction. The measured baseline is pinned as a band, the
shared-superblock duplication is pinned, and both hazards the sibling recorded are asserted:
the PromQL precedence trap (`(ratio) and rate(ops) > 1 > 0.050` returns a series on a healthy
60 ops/s mount; the shipped form returns none) and the op-rate guards (a mount doing half an
operation a second at 1 s/op response, 1 s/op queue and 20 deep in the backlog — 20x, 200x and
2.5x the three thresholds — must stay silent).
MUTATION-CHECKED, 14 mutations, every one of them making the test file FAIL: each of the five
thresholds moved in both directions where the fixtures allow it, both `unless` clauses deleted,
and all four rate guards loosened. The two clause deletions fail with an exp/got alert diff,
not a parse error. No threshold here is pinned only by a promql_expr_test restating it.
Live on prod, all five shipped expressions return NO series while all four of their
sub-expressions return six each — so the silence is a verdict, not missing data.
runbooks/node-io.md: the triage table grows from 10 rows to 15 (per-export server response
time, client queue time, our own demand, major timeouts, backlog depth), with real measured
HEALTHY values and an explicit "not collected" in both incident columns, because the collector
postdates both events and that can never be backfilled. A new four-way verdict table reads rows
11-13 together and maps each combination to the alert that says it.
HONEST REMAINING GAP: these rules rule US out; they cannot rule Proxmox IN. The per-client view
of an export exists only on the server. What would settle it is one read on 192.168.2.102 while
NFSExportServerSlowNotOurLoad is firing — `nfsstat -s` and /proc/fs/nfsd/clients/*/info — which
is out of scope from this repo. Recorded in the runbook.

docs: correct my own claim — node_nfs_* metrics DO exist; mountstats is the gap
I recorded that NFS was 'entirely unmonitored' with 'zero NFS observability',
based on a __name__ label-values query that came back empty. The query was at
fault: count({__name__=~"node_nfs.*"}) returns six live families on all three
nodes, and the nfs collector is on by default.
The real gap is narrower — node_mountstats_* is absent, and that is the one
carrying per-mount RPC round-trip time, so NFS latency specifically is
invisible while volume and retransmissions are not.
Two further signals already existed and had simply never been queried:
container_pressure_io_stalled_seconds_total, which names the stalling workload
and for tonight names sonarr; and etcd_request_duration_seconds via the
apiserver job, which the node-io runbook had explicitly claimed did not exist.
Also tempers the Proxmox hypothesis I floated: prod-1 was doing 114 NFS reads/s
of its own during the spike, so our traffic is substantial and the stall is not
obviously unexplained by us.

merge: I/O pressure alerts now name the cause, not just the stall
NodeIOPressureCritical fired on prod-1 and said nothing about why; establishing 'not a failing drive' took eight ad-hoc queries after the fact. Eight new rules each name a class in the summary — device saturation, device latency, NFS transport, etcd, not-local-disk, and which container is stalled — with the companion PromQL in a diagnostic_query annotation, a WHY row on the existing dashboard, and a 10-row triage table in runbooks/node-io.md carrying real HEALTHY / 2026-09-14 / 2026-09-07 columns. The discriminator is NodeIOPressureNotLocalDisk, written with 'unless' rather than 'and ... < T' on purpose: an empty right-hand side removes nothing, so it still fires when devices are too idle to have a measurable per-op latency — 'and <' would go silent in exactly the state it exists to detect. Acceptance is checked against both real profiles. Tonight: NotLocalDisk fires and ContainerIOStallHigh names sonarr. 2026-09-07 re-queried live at offset 164h: 1,039 ms per write on prod-1 sda, so the latency rules fire and name the device while NotLocalDisk correctly stays silent. Healthy state: all quiet. 10 mutations applied, 10 killed — one initially survived and exposed a threshold pinned only by a test that restated it. Corrects two claims: the runbook said no etcd fsync metric exists, but etcd_request_duration_seconds is present via the apiserver job and attributes per node; and container_pressure_io_stalled_seconds_total was already scraped with ~400 series and unqueried. Also fixes two bugs found in the work itself: a PromQL precedence error where 'ratio and rate(ops) > 10 > T' compares T against the op rate rather than the ratio, and node-exporter extraArgs replacing rather than appending, which would have silently dropped the chart's filesystem excludes. |

fix(monitoring): node-exporter extraArgs REPLACES the chart default, so restate it
Verified against the chart (helm show values prometheus-community/prometheus-node-exporter) and against the live DaemonSet's argv on prod: the subchart's extraArgs default is NOT empty — it ships the two filesystem excludes (mount-points-exclude for /dev,/proc,/sys,containerd,docker,kubelet and the fs-types-exclude list). Setting extraArgs to just --collector.mountstats would have silently dropped both, so the filesystem collector would have begun reporting every container overlay and every kubelet bind mount: a large cardinality jump, and a behaviour change in NodeDiskFillingUp, which alerts per mountpoint. Both defaults are now restated verbatim alongside the new collector, with a note to re-reconcile them on a chart upgrade. Co-Authored-By: Claude Opus 5 <[email protected]> |

chore(conformance): shrink UNTESTED_ALERTS by the two PSI detectors
node-io-cause.test.yaml's healthy fixture asserts NodeIOPressureHigh and NodeIOPressureCritical quiet on the same measured prod state the eight new cause rules are pinned against — the point of that fixture being that the detectors and the cause rules must agree about what "healthy" is. The shrink-only register entries are therefore stale, and the gate correctly refused them. Co-Authored-By: Claude Opus 5 <[email protected]> |

feat(monitoring): name the CAUSE of node I/O pressure, not just the stall
NodeIOPressureCritical has now fired twice on k3s-prod-1 for opposite causes and
said the same thing both times. On 2026-09-14 02:40-02:45Z it fired at PSI(full)
20.98% — twice the threshold, four times the 2026-09-07 level — while every local
device was idle (0.09-0.27 utilisation) and fast (1.4-4.8 ms per write), NFS
retransmissions were zero and no Longhorn volume was degraded. Establishing that
took eight ad-hoc PromQL queries after the event had already recovered.
Adds the group platform-health.node-io-cause: eight rules, one per cause class,
each naming its cause in its own summary.
NodeDiskDeviceSaturated device saturation >0.85 busy, 10m
NodeDiskWriteLatencyHigh device latency >20ms/write, 10m
NodeDiskWriteLatencyCritical device latency >50ms/write, 5m
NodeDiskReadLatencyHigh device latency >250ms/read, 15m
NodeNFSRetransmissionRateHigh NFS transport >1% retransmitted, 10m
NodeIOPressureNotLocalDisk not local disk PSI>10% with all of the above absent
NodeEtcdRequestsSlow etcd >0.5% of etcd requests over 1s
ContainerIOStallHigh which workload per-container PSI >15%
Every threshold is measured on prod over 24-48h, not guessed, and each rule
records its headroom. The PSI thresholds themselves are deliberately unchanged:
the 21% stall was real, it fired twice in 24h for two real events on the one node
that has a problem, and raising the bar would also have raised it above the 11.36%
at which prod-1 was already losing etcd on 2026-09-07.
Context reaches the operator at page time three ways: the summary states the cause
class; every rule carries a diagnostic_query annotation with the exact companion
PromQL; and node-pressure-dashboard.yaml gains a WHY row (seven panels) plotting
saturation, write/read service time, NFS retransmissions, our own NFS op rate,
the etcd slow-request fraction and per-container PSI side by side. runbooks/node-io.md
gains a 10-row triage table with the real healthy / 2026-09-14 / 2026-09-07 columns,
which turns those eight queries into a two-minute read.
etcd and NFS metric availability, verified on prod rather than assumed:
* etcd SERVER disk metrics do NOT exist. etcd_disk_wal_fsync_duration_seconds and
etcd_disk_backend_commit_duration_seconds are absent (kubeEtcd disabled for k3s);
a query for etcd_disk_*/etcd_server_*/etcd_mvcc_* returns nothing at all.
NodeEtcdRequestsSlow uses the apiserver's client-side view of its own local
member instead, and says in its own description that it is a proxy.
* node_nfs_* DOES exist — the nfs collector is on by default, host-wide via
/proc/net/rpc/nfs, confirmed on all three nodes. It gives op counts and
retransmissions and NO latency, so it can see a dropping export but not a slow
one. The mountstats collector is enabled here to close that gap; NO rule
references node_mountstats_* yet, because the series do not exist until the
HelmRelease rolls out and the collector's visibility through the node-exporter
mount namespace must be verified on prod first. The runbook records the check
and says to revert if it comes back empty.
Proof, per the repo's two shipped alerting failure modes:
* platform/monitoring/tests/node-io-cause.test.yaml — 7 fixtures, all from
measured profiles: healthy (all 8 quiet), 2026-09-14 (NotLocalDisk fires and
names sonarr), 2026-09-07 re-queried at offset 164h (write-latency and etcd
fire, NotLocalDisk correctly silent), rebuild storm, NFS transport, read
latency, and the `unless` semantics.
* 10 mutations of the shipped rules, all killed. The mutation run found a real
gap: the etcd threshold could be changed without failing any test, because it
was only pinned by a promql_expr_test that restated the threshold in the test
file. An alert_rule_test now pins it.
* All 11 referenced metrics verified to return series on prod with
`promtool query instant`, and all 8 expressions verified quiet on today's state.
Also extends the alert-metrics-have-scrape-targets owner table for container_*
(the kubelet ServiceMonitor's cAdvisor path, which this entry already claimed in
its title) and for etcd_request_duration_seconds_* by EXACT NAME, deliberately not
by an etcd_ prefix, so a future rule on the unscraped etcd_disk_* names still fails
the gate.

docs(pm): owner decisions — files stay, workloads stay, instrument NFS instead
Records three owner decisions and the finding that makes the third tractable. The /downloads malware stays: the Proxmox-hosted stack still has operational control of those files so deletion just triggers a re-download, nothing but the arr suite touches the directory, and there are no Windows machines anywhere — which removes the exposure I was concerned about. Written down so nobody 'discovers' and deletes them later. Anti-affinity for the co-located NFS pods declined; the concentration is accepted rather than overlooked. And the enabling finding: there are NO NFS metrics in the TSDB at all — node-exporter's nfs and mountstats collectors are off by default. A cluster with four NFS mounts carrying the media library and legacy Nextcloud data has zero NFS visibility, while PSI counts NFS stalls as I/O stalls. That is precisely why a 20.98% stall alongside idle local disks could not be explained. Co-Authored-By: Claude Opus 5 <[email protected]> |

docs: prod-1 I/O critical was not a failing disk; confirmed malware in /downloads
NodeIOPressureCritical fired on prod-1 (peak 20.98% PSI, recovered
unattended) — the first time this alert has fired on prod, and only because
the scrape gap was closed yesterday.
Evidence rules out the 2026-09-07 drive repeat: 3.5 MB/s of writes, device
utilisation 0.09-0.21, write latency 1.4-4.8 ms, zero NFS retransmissions,
21.4 MB/s NFS throughput, no degraded Longhorn volumes, and KSM never observed
NotReady. A 21% stall on trivial volume with healthy latency is transient
blocking I/O, not hardware — and PSI counts NFS too.
Structural finding: sonarr, qbittorrent and jackett all run on prod-1, the
node with the I/O history. Same concentration class as the CNPG primaries.
Separately, the /downloads files are confirmed malware: two PE executables
('MZ') sharing one MD5, padded to ~926 MB and named as two different shows,
plus a ZIP masquerading as video. Not executed, cluster not compromised; the
risk is a Windows client opening them.

docs: correct a misattribution — 192.168.2.1 is the SOHO router, not pfSense
I wrote that pfSense was stripping the RFC1918 answers. The operator corrected it, and this repo already documented the topology I failed to read: 192.168.2.0/24 is pfSense's WAN (clusters/prod/kustomization.yaml:458, cluster-vars.yaml:190, DECISIONS-LOG 1772), pfSense lives on 192.168.1.0/24, and 192.168.2.1 was already recorded here as 'both gateway and only IPv4 resolver' and flagged as a SPOF (entries 1318, 1468). The measurement is unchanged — that resolver returns NOERROR/ANSWER:0 for this zone while resolving cloudflare.com — but the attribution invalidated my preferred fix: configuring pfSense cannot help, because prod's resolver path never reaches it. Fixes reordered accordingly. Exposing Pi-hole's DNS to the LAN is now first: it is the architecture the repo already claims, it does not depend on a consumer router's feature set, and it retires the single-resolver SPOF this log flagged months ago. Configuring the SOHO router drops to second, since many such devices cannot express a domain override and it is outside GitOps regardless. Co-Authored-By: Claude Opus 5 <[email protected]> |

docs: LAN split-horizon DNS is documented but unimplemented; pfSense strips the answers
The workstation could not reach sonarr.home.keithjackson.dev. The stale dnsmasq override pinning the zone to dev's dead 192.168.2.50 was the obvious cause, but removing it — which is what I was about to recommend — would not have fixed it: pfSense returns NOERROR/ANSWER:0 for this zone while resolving cloudflare.com fine, the signature of private-address rebind filtering, since the zone legitimately points at RFC1918 space. The underlying gap: coredns-custom.yaml defers LAN clients to 'PiHole split-horizon', but Pi-hole's Service is ClusterIP with ports 80/4180 — it serves no DNS at all. So the LAN half of split-horizon does not exist and each client silently depends on a hand-maintained file. Records the corrected override (staged for the operator's sudo) and the three proper fixes, none applied. Co-Authored-By: Claude Opus 5 <[email protected]> |

docs(readme): DR restore is proven on prod — Phase 7's remaining item is node-loss
R-STATE-03 reads proven in --status as of 2026-09-14, the first requirement in this repo to reach that state, with both verifiers recorded on prod. Also states why the earlier PROVEN: 0 was the honest answer rather than a bug: a proof is a claim about a specific tree on a specific cluster, so coverage (51/51) and proof are two different questions.

test(conformance): record the L0 verifier for R-STATE-03 / R-ENV-02
A requirement reads PROVEN only when EVERY verifying test has a fresh ledger row — the state is the minimum across them, so a test with no row contributes not-derivable and one recorded verifier cannot manufacture green. R-STATE-03 carries two executable verifiers (L0 + L3). The L3 dr-restore proof landed in bd17b65; this records the L0 side, placeholder-guard-coupling, which also carries R-ENV-02. Worth noting it is the test that was permanently SKIPPED until earlier today — it was hiding a red, and now it runs and is recorded. Co-Authored-By: Claude Opus 5 <[email protected]> |

test(conformance): R-STATE-03 PROVEN on prod — DR restore from R2, off-cluster
Phase 7's outstanding exit criterion. The only previous dr-restore proof was
recorded on the dev cluster (decommissioned 2026-09-12) against MinIO, so it
could not speak for prod or for today's Cloudflare R2 target.
Run 20260914T021505Z-24b8111, env=prod, kube v1.36.4+k3s1, chainsaw v0.2.12,
150.70s, 1 passed / 0 failed / 0 skipped. Sentinel
DR_RESTORED_FROM_OFF_CLUSTER_BACKUP_OK.
What makes it a real proof rather than a green check: the test seeds a canary
on the replicated longhorn class, backs the namespace AND volume data up to
the off-cluster store, then DESTROYS every in-cluster copy — namespace, PVC
and PV — before restoring into a clean, previously-nonexistent namespace. It
asserts the restored PVC binds a DIFFERENT PersistentVolume
(pvc-f0c061e1 != pvc-4107d59d) and fails explicitly if it rebinds the
original, because that would be an in-cluster survival masquerading as a
restore. The canary came back byte-identical.
It touches no real service's namespace, PVC or PV — the scratch namespaces are
named after its own Chainsaw namespace and are destroyed by design.
This is the run whose first attempt was discarded for recording env=dev; the
recorder fix is
|
||
|
|
24b8111d0c |
fix(conformance): the ledger stamped every proof env=dev regardless of cluster
record_run.py defaulted --env to the literal 'dev'
(os.environ.get("CONF_ENV", "dev")) and run.sh hardcoded the same fallback
at both call sites, while CONF_ENV is set nowhere in this repo. So every
recorded proof claimed dev no matter which cluster it ran against.
Harmless while dev was the only cluster. Dev was decommissioned 2026-09-12,
and today a genuine DR-restore run against k3s-prod was recorded as
env=dev — caught before it was committed, and the record discarded rather
than hand-edited. A proof that lies about WHERE it was proven is worse than
no proof, because locating the demonstration is the ledger's whole job; it
would also have looked like a sixth dev-only row while actually being the
prod proof Phase 7 is waiting on.
env is now derived from k3s-prod (k3s-prod -> prod),
which cannot drift from the cluster the run actually talked to. An
undeterminable context records 'unknown', never a cluster name, and an
unexpected context is recorded verbatim so it is visible rather than coerced.
CONF_ENV still overrides. Recorder selftest passes.

docs: README status was stale by a whole phase; record the R-STATE-03 decision
The Status section still said phases 0-6 were deployed on the DEV cluster and that Phase 7 was not open with clusters/prod 'a design-only overlay'. Dev was decommissioned on 2026-09-12 and prod has been the live cluster serving the apex since. It also claimed 36/51 requirements covered with a safety-critical gap, and that Velero was blocked on OQ-BKP. Now states Phase 7 as open with its three exit criteria and which one is actually outstanding; corrects the node inventory from the Proxmox dev IPs to the bare-metal prod nodes; records Velero as unblocked to R2; and adds the distinction the old text elided — coverage (51/51) is not proof (PROVEN: 0), because the only dr-restore and node-loss proofs were recorded on a cluster that no longer exists, against MinIO rather than R2. Also records the owner's decision that Velero+kopia to R2 is the accepted volume backup, with no Longhorn backup target, and that Longhorn config belongs in source.

merge: the Longhorn I/O caps the runbook promised are now actually declared
runbooks/longhorn-degraded.md asserted concurrentVolumeBackupRestorePerNode- Limit and snapshotHeavyTaskConcurrentLimit were tightened 5 -> 1 after the 2026-09-07 etcd I/O starvation. Both read 5 on prod and neither name existed anywhere in the repo. Now declared in the helmrelease defaultSettings, the path Flux actually reconciles. Both go to 1 rather than 2, and the cost is smaller than I assumed: velero's schedules run defaultVolumesToFsBackup, i.e. kopia through the node-agent, so they are not Longhorn volume backups and this setting does not bind them; CNPG's base backups are barman-level; and Longhorn has no backup target configured at all. Purge work comes from rebuild cleanup, which is already serialised to 1/node, so 1 keeps pace with its own generator while 2 would add a second heavy writer during exactly the rebuild that starved etcd. Also declares nodeDrainPolicy, which was only ever Longhorn's own default — present in no manifest and no rendered ConfigMap, so an upstream default change would have moved it silently while two runbooks reason about drain safety from it. Value unchanged. The Ansible etcd_io_priority role is deliberately NOT ported. The pathological drive it was written for has been replaced (I/O PSI 11.36 -> 3.79 under the same load class), the role was never run against any cluster, and its own README concedes it cannot separate the tenants because they share one ext4 filesystem. Swapping the elevator and halving nr_requests on the live device holding etcd's WAL is a node-wide blast radius for a low ceiling. Kept as a named operator option; the real fix remains giving etcd its own device. Removes orphanAutoDeletion, re-verified present-and-inert two ways: helm template emits no orphan key for it, and the live setting is NotFound. |

fix(longhorn): the I/O caps a runbook promised were never declared — declare them
`runbooks/longhorn-degraded.md` told operators that, after the 2026-09-07 etcd
I/O-starvation incident, `concurrentVolumeBackupRestorePerNodeLimit` and
`snapshotHeavyTaskConcurrentLimit` had been tightened 5 -> 1. Measured live on
prod today: both read **5**, and neither name appeared anywhere in this
repository — so nothing declared them and nothing would have restored them.
Fourth instance of config that looked applied and was not.
Landed in `platform/longhorn/helmrelease.yaml` `defaultSettings` (the path Flux
reconciles; `values.yaml` is the reference mirror), NOT by `kubectl patch` —
a hand-applied Setting is exactly how this gap arose and Helm would silently
rewrite it on its next upgrade.
concurrentVolumeBackupRestorePerNodeLimit 5 -> 1
snapshotHeavyTaskConcurrentLimit 5 -> 1
replicaReplenishmentWaitInterval 600 PINNED, unchanged
backupConcurrentLimit / restoreConcurrentLimit 2 / 2 PINNED, unchanged
concurrentAutomaticEngineUpgradePerNodeLimit 0 PINNED, unchanged
nodeDrainPolicy block-if-contains-last-replica PINNED — it was in
force only as Longhorn's OWN DEFAULT, declared in no manifest and in no
rendered ConfigMap, so an upstream default change would have moved it
silently while two runbooks reasoned about drain safety from it.
EVERY KEY PROVEN TO LAND, not assumed. `helm template longhorn/longhorn
--version 1.12.1` (the version this chart range resolves to, per the
HelmRelease's own lastAttemptedRevision) on this branch's spec.values,
substituted as clusters/prod substitutes them, emits all eight into the rendered
`longhorn-default-setting` ConfigMap in kebab-case. Diffed against the LIVE
ConfigMap the change is purely ADDITIVE: 8 keys added, none altered, none lost.
The chain to the Settings is verified read-only on prod — all 115
settings.longhorn.io carry `longhorn.io/configmap-resource-version: 7917`
(= that ConfigMap's resourceVersion) with `status.applied: true`, and every key
in the ConfigMap equals its Setting's value. The two targets sit at 5 with the
key absent, i.e. Longhorn defaults, as measured.
`orphanAutoDeletion: true` REMOVED, verified inert two independent ways against
the deployed 1.12.1: the render emits no orphan key at all (Longhorn 1.9 renamed
it `orphanResourceAutoDeletion`, a list, and the chart drops unknown
defaultSettings keys with no error), and live, `setting/orphan-auto-deletion` is
NotFound while `orphan-resource-auto-deletion` reads "". Deliberately NOT
replaced — orphan deletion is extra writes on the constrained partition and buys
only space. Orphan cleanup stays manual by decision; the two runbooks that cite
the key by name are corrected rather than left to go stale.
BOTH NEW CAPS ARE 1, AND 1 COSTS SOMETHING — stated, not waved at.
`concurrentVolumeBackupRestorePerNodeLimit: 1` costs nothing TODAY: Longhorn has
no backup target (the `backup-target` Setting does not exist; still the
WS-STORAGE Phase-4 TODO), and velero's nightly run is not a Longhorn backup —
`snapshotVolumes: false` + `defaultVolumesToFsBackup: true` is kopia
file-system backup through velero's node-agent, which this Setting does not
gate; CNPG base backups are barman-level and ungated too. Its only consumer is
an R-STATE-03 restore, where serialising ~24 volumes beats losing etcd
mid-restore. Revisit when a Longhorn backup target lands.
`snapshotHeavyTaskConcurrentLimit: 1` rather than 2 because purge work is
generated by rebuild cleanup (auto-cleanup-system-generated-snapshot true, NO
RecurringJobs, 24 volumes / 24 snapshots) and rebuild is already serialised to
1 per node — so 1 keeps pace with its own generator, where 2 buys backlog drain
at the price of a second heavy writer during the exact rebuild that starved
etcd. The cost: space reclaims serially after a rebuild storm — real here (a
37.7 GiB snapshot once pinned a volume at 97.3% allocated), but instrumented by
LonghornDiskAllocationHigh and recoverable by hand, where a wedged etcd is not.
Headroom on the record: I/O PSI full is 0.30/0.62/0.37 % now, and 3.79 under a
full 18-replica rebuild after node 1's drive replacement, against a 5% warning
threshold. These caps are a BOUND, not a fix — etcd and Longhorn still share one
ext4 filesystem and nothing arbitrates the jbd2 journal fdatasync waits on.
NOT PORTED, deliberately: the same unmerged branch's node-level I/O arbitration
(`roles/etcd_io_priority` — BFQ on the shared device, nr_requests 64 -> 32,
systemd IOWeight drop-ins). The 2011 C400 it was written for was replaced on
2026-09-07 and the same load class measured 11.36 -> 3.79 I/O PSI with the node
Ready throughout; the role was never run against any cluster, its author
recorded it as unproven with a node-3-first sequenced rollout, and its own
README concedes it does not separate the two tenants. Node-wide blast radius,
low ceiling, stale measurements (node 1 reinstalled, founder moved to node 2).
It stays an operator option if I/O PSI climbs back toward 5% — which, unlike in
September, we would now be told about. Nothing under infra/ansible/ is touched.
ALSO ALREADY DONE, so skipped: that branch's NodeIOPressureHigh/Critical and the
dashboard I/O row are on main already (

fix(monitoring,runbook): 5 GiB is not compaction headroom, and a runbook claimed an I/O cap that was never applied
Two things found while reviewing the Longhorn alert work. Prometheus retentionSize was 45GiB of a 50Gi PVC, under a comment already naming the right intent — 'headroom for WAL + head + compaction scratch'. 5 GiB is not that: retentionSize counts only persisted blocks, and a large compaction can need roughly the size of the blocks being merged. ENOSPC on /prometheus wedges every WAL commit, so scrapes keep succeeding while nothing is stored and every absent()/==0 alert fires falsely at once. Lowered to 36GiB, which costs no history: the TSDB is 11.2 GiB at 30d, so 30d remains the binding limit. runbooks/longhorn-degraded.md asserted that concurrentVolumeBackupRestore- PerNodeLimit and snapshotHeavyTaskConcurrentLimit 'was actually tightened 5 -> 1'. Both read 5 on prod and neither name appears anywhere in this repo — the work is on the unmerged fix/etcd-io-priority branch. The page is read during etcd I/O starvation on a node whose WAL shares a device with Longhorn, so it was telling an operator mid-incident that the cap they depend on is in place when it is not. Corrected, with the two mitigations that ARE real named and a command to verify any of them. Co-Authored-By: Claude Opus 5 <[email protected]> |

merge: Longhorn alerting measured the wrong things, three ways
(1) LonghornVolumeCapacityHigh alarmed on ALLOCATION while calling itself a capacity alarm. Prometheus's TSDB volume read 0.973 while the kubelet saw the same filesystem at 0.208, because 37.73 GiB of it is a Longhorn SYSTEM snapshot — the kind taken for the full replica rebuild that prod-1's drive replacement forced — growing +152 MB/h while the filesystem stayed flat. The rule was therefore unclearable by design, i.e. permanently firing. Deleted as redundant, shown rather than asserted: 23 of 24 volumes fall under the kubelet-based filling rules, and the 24th is volumeMode Block, which the deleted rule was not covering either. (2) LonghornVolumeDegraded and LonghornVolumeFaulted could not fire even with the scrape working. longhorn_volume_robustness on 1.12.1 is ONE-HOT over a state label with values 0/1, not the 0-3 enum the rules and their comment assumed, so a faulted volume would have alerted nobody. This survived the scrape fix landing hours earlier. (3) LonghornNodeStorageHigh was wrong twice: its 0.85 threshold sat above the 75% at which storage-minimal-available-percentage=25 already removes a disk from the scheduling pool, and longhorn_node_storage_usage_bytes SUMS a node's disks, so one full disk hid behind a half-empty sibling. Replaced with per-disk LonghornDiskAllocationHigh (>0.70) and LonghornDiskUnschedulable, the latter reading Longhorn's own verdict instead of re-deriving a formula from three settings no metric exports. Baseline green with 11/11 mutations red. retentionSize 45GiB of 50Gi and discard/TRIM are both REPORTED with recommendations, not changed: TRIM would not have helped here, since remove-snapshots-during-filesystem-trim is false and the 37.7 GiB is a snapshot. # Conflicts: # DECISIONS-LOG.md |

fix(monitoring): delete the Longhorn rule that measured allocation and called it capacity
LonghornVolumeCapacityHigh went pending within minutes of the Longhorn scrape
landing today. Re-measured on prod: it read 0.9731 on the Prometheus TSDB volume
(actual_size 52243681280 / capacity 53687091200) while the kubelet reported the
SAME filesystem 20.8% used. actual_size is head + pinned snapshots, and one
user_created=false system snapshot from prod-1's replica rebuild holds 40510484480
bytes (37.7 GiB) of it; Longhorn returns no freed blocks without discard/TRIM, and
retentionSize 45GiB on a 50Gi volume targets 90% by design. The ratio is pinned
near 1.0 and cannot fall back under 0.85 — a permanently-firing alert, the same
shape as CNPGNoRecoverabilityPoint.
DELETED, not re-thresholded. Raising the threshold would tune away a true
statement about allocation. Redundancy proven, not asserted: of 24 Longhorn
volumes on prod, 23 appear in kubelet_volume_stats_inodes > 0 and so fall inside
MonitoringVolumeFillingUp (namespace="monitoring") or PersistentVolumeFillingUp /
PersistentVolumeAlmostFull. The 24th is unifi/unifi-rootdisk, volumeMode Block —
no filesystem for anyone to measure, and the deleted rule was not covering it
either.
AND A SECOND INERTNESS the scrape did not fix. longhorn_volume_robustness on
longhorn 1.12.1 is one-hot over a `state` label with values 0/1, not the 0-3 enum
the rules assumed:
count(longhorn_volume_robustness) => 96 (24 volumes x 4 states)
count by (state) (longhorn_volume_robustness == 1) => {state="healthy"} 24
count(longhorn_volume_robustness == 2) => (empty)
count(longhorn_volume_robustness == 3) => (empty)
So a FAULTED volume would still have alerted nobody. Re-keyed to the label; the
"44 series / 72 unknown(0, detached)" note in platform/longhorn/helmrelease.yaml
was the same misreading and is corrected in place.
The allocation question moved to where allocation is a budget. LonghornNodeStorageHigh
fired at 0.85, but storage-minimal-available-percentage is 25 on this cluster, so a
disk leaves the scheduling pool at 75% used — the old threshold could only fire
after scheduling had already been refused. Replaced by:
LonghornDiskAllocationHigh (longhorn_disk_usage_bytes / longhorn_disk_capacity_bytes) > 0.70, 30m
LonghornDiskUnschedulable longhorn_disk_status{condition="schedulable"} == 0, 15m
Per DISK, not per node: longhorn_node_storage_usage_bytes sums a node's disks, so
one full disk could hide behind a half-empty sibling. Measured prod usage
0.2254 / 0.2306 / 0.2369 on prod-1/2/3.
PROVEN NEITHER PERMANENTLY FIRING NOR INERT. platform/monitoring/tests/longhorn.test.yaml
adds 6 cases pinning every rule quiet on today's measured prod state and firing on
a constructed bad state, with every `for:` asserted, plus regression assertions that
the old `== 2`/`== 3` forms match nothing and that per-disk 0.72 is visible where the
node-summed 0.475 is not. Mutation-checked 11 ways; each turns the suite RED. Live on
prod: all four new expressions return empty, while the sum of their selector
cardinalities is 54. The L0 UNTESTED_ALERTS register shrinks by seven (7/56 -> 14/58
alert rules unit-tested), which also brings MonitoringVolumeFillingUp,
PersistentVolumeFillingUp and PersistentVolumeAlmostFull under test since the
redundancy claim rests on them.
REPORTED, NOT CHANGED (DECISIONS-LOG, owner decisions): retentionSize 45GiB on a
50Gi volume is too tight — recommend 36GiB, with reasoning; and discard/TRIM on the
longhorn StorageClass is feasible but not advisable now — remove-snapshots-during-
filesystem-trim reads false on prod, so trim would not have reclaimed the 37.7 GiB
anyway, and continuous discard on nodes where the etcd WAL shares the spindle points
at this cluster's known failure mode.

docs(pm): two rendered manifests nothing applies — the keycloak one is a trap

eb2510837c |
merge: twelve app SLI rules could never fire — fixed in the generator
Each <app>-down rule read up{job=...} from a ServiceMonitor selecting a
Service port named 'metrics' that no app Service defined, so every one
discovered zero targets. PrometheusTargetsMissing could not see it either: a
target never discovered has no up series to be 0.
The port name was only the first of THREE layers. None of the twelve apps
serves Prometheus metrics natively at all — Plex, qBittorrent, the arrs,
Jackett, Pi-hole, Seerr, Semaphore and Nextcloud would each need an exporter,
and Gitea needs an app.ini flag. And every app namespace ships default-deny
ingress with no monitoring allow, so a correct port would still have been
dropped by policy — while renderer-contract.md claimed a baseline allow that
never existed.
Fixed in catalog/render.py (schema 1.6.0) rather than in twelve rendered
files: slis: [up] now renders <app>-down against kube-state-metrics
readiness, with an 'or absent(...)' half so the signal VANISHING fires
instead of silencing. The twelve dead ServiceMonitors are gone; a new
observability.metricsEndpoint renders the Service port, the monitor endpoint
and the scrape allow together, so the three cannot disagree again.
Deletion was rejected with evidence: kube-prometheus-stack's generic
kubernetes-apps rules are live, but they are namespace-keyed warnings, not
the per-service critical SLI R-OBS-01 asks for.
Two incidental finds: keycloak's rendered monitor was a duplicate pointing at
the wrong port, and platform/monitoring/tests/run.sh discovered test suites
only inside its own directory while documenting the convention as general —
so a suite added anywhere else was never run and still looked like coverage.

fix(obs): twelve app SLI rules read a signal that exists; kill the dead ServiceMonitors
Twelve `<app>-down` SLI rules were STRUCTURALLY INERT. Each read `up{job="<app>"} == 0`,
and the ServiceMonitor rendered beside it named `endpoints[].port: metrics` — a port NO
rendered app Service defined. Every monitor discovered ZERO targets, so no `up{job="<app>"}`
series existed and the rule could not fire. Verified on prod before this change:
`count by (job) (up)` listed 24 jobs and not one of the twelve appeared; `up{job="plex"}`
and `up{job="gitea"}` both returned nothing. `PrometheusTargetsMissing` could not see it
either — a target that was never discovered has no `up` series to be 0.
THE PORT NAME WAS NEVER THE MISSING PIECE. Ground truth per app: Plex, Pi-hole, Jackett,
qBittorrent, Sonarr, Radarr, Seerr, Semaphore and Nextcloud export NO Prometheus metrics
without a separate exporter sidecar; Gitea can but only with app.ini metrics enabled;
Keycloak does, on the operator's management port, already scraped by
platform/keycloak/servicemonitor.yaml; vm-demo is a KubeVirt VM with no Service at all, so
its monitor selected nothing whatsoever. `metrics: true` was asserting a fact none of them
had. There was also a THIRD layer of inertness nobody had hit yet: every app namespace ships
default-deny with `ingress: []` and the renderer emitted no monitoring allow, so even a
correct port would have been dropped by policy — while renderer-contract.md claimed the
baseline carried such an allow.
FIXED IN THE GENERATOR, not in twelve rendered files:
* `slis: [up]` now renders a `<app>-down` alert against kube-state-metrics readiness of the
service's own workload object —
`kube_deployment_status_replicas_available{namespace,deployment} == 0 or absent(...)`,
`kube_statefulset_status_replicas_ready` for a StatefulSet, and
`absent(kubevirt_vmi_info{namespace,name,phase="running"})` for a VM. The same idiom
KeycloakDown has used since it was fixed. kube-state-metrics IS scraped, so this needs no
exporter and no new target. The `or absent(...)` half is load-bearing: the signal
DISAPPEARING now fires the alert instead of silencing it.
* schema 1.6.0 adds `observability.metricsEndpoint` — WHERE metrics are served. A
ServiceMonitor is rendered ONLY from it, and it renders all three halves of a working
scrape together: the named Service port, the monitor endpoint, and the
monitoring-namespace CiliumNetworkPolicy allow. No catalog entry declares one, so twelve
dead ServiceMonitors are gone. `metrics: true` keeps meaning logs-to-Loki plus
kube-state-metrics liveness.
* schema 1.6.0 also adds `observability.livenessWorkload`, and catalog/keycloak.yaml uses
it. Keycloak's server is a StatefulSet run by the operator; the default Deployment shape
would have made its `absent()` half fire FOREVER — the other failure mode this repo has
shipped.
* renderer selftest gains cases 9/9a/9b/9c: no metricsEndpoint => no monitor; the up SLI
must not read `up{job=...}`; endpoint port must exist on the Service; the metrics port
must NOT reach the Gateway allow; an unknown livenessWorkload.kind is REFUSED.
PROOF, both directions, for all twelve (apps/wave-{0,1,2}/tests/app-slis.test.yaml, run by
platform/monitoring/tests/run.sh over the RENDERED manifests):
* quiet on the healthy state; firing on no-ready-replica; firing when the series is ABSENT;
the VM asserted both gone and in a non-running phase; per-app isolation asserted, and
keycloak asserted un-maskable by its neighbours (keycloak-operator Deployment,
keycloak-db StatefulSet ready in the same namespace).
* mutation-checked: six mutations, each turning its suite red — reverting plex to
`up{job=...} == 0`; dropping seerr's `absent()` half; pointing keycloak at a Deployment;
capitalising the VMI phase to `Running`; widening keycloak's matcher to the namespace;
inverting plex's `== 0` to `!= 0`. Control run green.
* live on prod with `promtool query instant`: all ten deployed app Deployments export
`kube_deployment_status_replicas_available`,
`kube_statefulset_status_replicas_ready{namespace="keycloak",statefulset="keycloak"}` = 2,
`kubevirt_vmi_info` present with a lowercase `phase="running"`; and evaluating the twelve
SHIPPED expressions returns no series for eleven (quiet, not permanently firing). The
twelfth is vm-demo, which is not in apps/wave-0/kustomization.yaml and so is not deployed
— its rule is not applied either.
DELETION WAS NOT THE ANSWER, and the evidence is recorded rather than assumed:
kube-prometheus-stack's `kubernetes-apps` group IS live on prod (17 rules, KubePodNotReady /
KubeDeploymentReplicasMismatch among them), so app pods are not unmonitored — but that is a
generic warning keyed to a namespace, not the per-service CRITICAL SLI R-OBS-01 declares.
platform/monitoring/alerts.yaml carries no generic app-readiness rule at all.
GUARD SO IT CANNOT RECUR SILENTLY: new whole-repo L0 invariant
conformance/tests/l0-static/servicemonitor-ports-resolve. It walks the MONITORS, not the
alerts, so it needs no `up{job=...}` rule to reach one, and resolves each endpoint by SELECTOR
across the whole tree rather than by same-file adjacency. Fixing the alerts DELETED the only
thing that made the broken monitors visible to the sibling check, which is exactly why this
axis needed its own home. It declares `conformance.home.k3s/scope: whole-repo` and adds no
ci/l0.sh stage. Proven to FAIL on the pre-fix tree: 15 failures — eleven port disagreements,
vm-demo's monitor matching no Service at all, and the three generator/contract assertions —
and to pass after. Its resolver is additionally proven on in-check fixtures (agreeing pair
accepted, disagreeing pair rejected, target-less endpoint rejected), because after the fix
there are zero in-repo monitors left for it to judge and a guard whose only evidence is
"nothing failed" cannot be told apart from one that stopped working. It also asserts
r_servicemonitor does not HARDCODE a port name — the mechanism by which one edit gave twelve
services the same wrong one.
Also fixed, found on the way:
* platform/monitoring/tests/run.sh discovered the SUITE convention only inside
platform/monitoring/tests/ while documenting it as general — a suite added anywhere else
was never run and still looked like coverage. Now discovered tree-wide; a misplaced
*.test.yaml fails loudly instead of vanishing.
* KNOWN_UNWIRED_JOBS in alert-metrics-have-scrape-targets is now EMPTY, and the twelve
apps/* entries in alert-rules-unit-tested's UNTESTED_FILES are gone — both because the
gaps were CLOSED, not waived. Both registers are shrink-only and a stale entry fails.
* renderer-contract.md claimed the default-deny baseline carried a standing monitoring
scrape allow. It never did; the claim is corrected and the allow is now real, per declared
metrics endpoint and scoped to that one port.

fix(qbittorrent): the comment warning about doubled dollars contained one
The new flux-postbuild-substitution guard failed the merge on
apps/wave-0/qbittorrent.yaml:155 — a run of two dollars in a substituted
path that nothing justifies. It was inside the postStart hook's own comment
EXPLAINING the hazard: prose about what envsubst does to a doubled dollar,
written with a literal doubled dollar.
Functionally harmless — it is a bash comment, and collapsing it changes no
behaviour — but the guard cannot distinguish a comment from content that
reaches the workload, and it is right not to try: that is precisely how the
nextcloud-db break slipped through. Reworded in words instead.
Worth recording that this is the second time today the same trap caught an
explanation of itself: my own fix for the nextcloud-db incident (

merge: coverage debt paid — 51/51, and the root really did hide a service
R-C2-01 and R-C2-02 were the last two uncovered requirements (49/51). Now
100% with 0 gaps, via an offline L0 check (49 assertions) that compares two
repository facts: every home-zone hostname the repo routes over HTTP must be
linked from the apex dashboard, and every link the dashboard offers must
resolve to something the repo actually serves at L7 or L4.
'A service the root hid' was still a live defect: crafty.${BASE_DOMAIN} was
served and reconciled while nothing on the root linked to it. Committed RED
first so the history shows the check catching it, then fixed.
Also fixes a regex that could never have worked: ci/touched-requirements.sh
matched R-[A-Z]+-[0-9]+, where [A-Z]+ eats the C of R-C2-01 and then demands
a dash where the 2 is — so a manifest declaring either ID attributed nothing.
Every other consumer already used [A-Z0-9]+.
16 mutations proven caught. R-TLS-02's drafted amendment is recovered into
DECISIONS-LOG: revocation is not implementable with cert-manager, and the
choice between amending the requirement and a reviewed DOCUMENTED_GAPS entry
is the owner's.

merge: qBittorrent has a durable credential, and the arrs work again
qBittorrent 5.x minted a new temporary admin password on every process start, so the Sonarr/Radarr download clients broke on the next restart — and had already broken: both reported isValid: false, Authentication Failure. A SOPS secret is now the single source of truth and a postStart hook derives qBittorrent's stored PBKDF2 form on every container start, then logs in to prove it. The hook rather than a CronJob because the failure IS a container start: qbittorrent-nox reads the credential once at start from an RWO PVC the app holds, so a 15-minute cron leaves a window after every restart where both arrs are broken. An initContainer cannot do the ground-truth login. Proven: testall flipped false -> true on both arrs, and survived a real pod deletion and recreation with the conf still holding both keys. Two bugs found in the inherited work, both the envsubst trap again: a doubled-dollar port expansion that bash read as its own PID, which made the hook report 'the WebUI rejected the credential' three times without ever asking it anything; and one shared wait budget that let the first attempt burn all 90s. Also caught that the SOPS file was never listed in apps/wave-0/kustomization.yaml, so Flux would never have applied it — the live Secret was not going to be adopted at all. |

fix(monitoring): kube-state-metrics was OOMKilled 91 times — 13 rules went intermittent
Working set measured at 111 MiB with a 6h peak of 123.3 MiB against a 128Mi limit, so it died on every spike — exit 137, roughly every 11 minutes, 91 restarts in 16h. The consequence is worse than the restarts. Thirteen alert rules read kube_* series, so each kill made them intermittently unable to fire, which is the quiet version of the inert-alert class found elsewhere today; KubePodNotReady and KubeDeploymentReplicasMismatch were both sitting pending on it. Self-inflicted: enabling customResourceState for the Velero Schedule metrics earlier today added a CRD informer plus the mandatory CRD list/watch, and that marginal cost crossed a limit already sitting about 4 MiB above the working set. Raised to 384Mi, roughly 3x the observed peak, which costs nothing on nodes reporting 18.7-22.3 GiB available. Co-Authored-By: Claude Opus 5 <[email protected]> |

fix(qbittorrent): a durable WebUI credential, and the two bugs the WIP hid
Finishes the inherited WIP. qBittorrent 5.x had no WebUI\Username or
WebUI\Password_PBKDF2 in its conf, so it minted a NEW random admin password on
every process start. Both consequences had ALREADY fired: measured before this
change, `POST /api/v3/downloadclient/testall` returned isValid:false with
"Authentication Failure" on BOTH Sonarr and Radarr, so Completed Download
Handling was silently broken, and no human had a stable login either.
Mechanism: the SOPS/age qbittorrent-bootstrap Secret is the single source of
truth; a lifecycle.postStart hook derives qBittorrent's own stored form
(PBKDF2-HMAC-SHA512, 100000 iterations, 16-byte salt, 64-byte digest) and
asserts it into the conf on EVERY container start, then logs in to the WebUI to
prove it. Level-triggered like the repo's CronJob reconcilers, but triggered by
the container start because the failure it closes IS a container start: a cron
would leave a window after every restart in which the app serves a random
password, and would have to edit an RWO PVC from outside, under a running
process. AuthSubnetWhitelist was rejected — authentication is not weakened.
Two real bugs found in the WIP, both the postBuild-substitution trap:
* PORT came from a doubled-dollar WEBUI_PORT expansion. Correct on the cluster
(envsubst collapses it) and the renderer accepts it, but run any other way
bash reads the doubled dollar as its PID, so every curl got an unparseable
URL and the hook logged "the WebUI rejected the durable credential" three
times having never asked it anything — see the marker log at 05:35Z. Now a
literal PORT=8080; the script contains no braced expansion at all and
behaves identically however it is run.
* One shared wait budget covered both the s6 wait and the API wait, so the
first consumed all 90s and attempts 2-3 fired instantly. Separate counters
now; "the API never answered" is reported as a distinct fault from "the
password was rejected"; and a rejection restarts qbittorrent-nox so a retry
can actually change its outcome.
apps/wave-0/kustomization.yaml did not list the SOPS secret, so Flux would never
have applied it and the adoption of the live-only, kubectl-client-side-apply
qbittorrent-bootstrap Secret would silently not have happened. Listed now; the
decrypted values are SHA-256-identical to the live Secret's, so adopting it
cannot change the password.
Proven on prod: testall flipped isValid false -> true on both apps; after
deleting and recreating the pod the conf still held both keys, the WebUI answered
Ok. to a login with the credential decrypted from git, and both arrs still
reported isValid:true. The post-envsubst manifest was audited as `flux build
kustomization` emits it (no doubled dollar, no braced expansion, PORT=8080,
bash -n clean) and the hook's write path was exercised in-container against a
scratch conf: exit 10 when the keys are absent, exit 0 and a byte-identical file
on a second run, digest verified by an independent PBKDF2.
NOT proven, and recorded as such in DECISIONS-LOG: the hook has not yet run as a
real postStart on prod — the Deployment is Flux-owned from main and both routes
to the live object were refused by the session's permission classifier. Verify
on merge that the marker log gains a VERIFIED line on the next pod start.

docs(pm): R-TLS-02 needs the owner — the drafted spec amendment, recovered and restated
The R-TLS-02 analysis and its drafted spec amendment were written on
feat/coverage-debt-paydown (b37defe, 2026-09-07) and lived ONLY in that branch's copy of
DECISIONS-LOG.md. That branch's tree is ~107 commits behind main and must never be merged,
so the amendment went out of view with it — the second time this decision has been raised
and lost. Recovered, re-checked against today's main, and written where it cannot vanish
with a branch.
THE SUBSTANCE IS UNCHANGED. R-TLS-02 says certificates MUST be automatically "issued,
renewed, and revoked without manual steps". Issuance and renewal hold. Revocation is not
implemented and is not implementable with the stack ADR-0006 selects: cert-manager has no
revoke-on-delete, no Certificate field requesting revocation, and no controller that calls
ACME revokeCert, and neither ADR-0006 nor docs/08 specifies a mechanism.
enableCertificateOwnerRef is NOT the remedy — it garbage-collects the Secret, which is
cleanup, not revocation — and it is a global controller flag that would drop the Gateway's
wildcard-home-tls Secret on any future Certificate rename/prune, so it needs its own risk
assessment rather than a side effect of a test task. Still not set.
WHAT CHANGED SINCE THE FIRST ESCALATION, and why it now matters more: R-TLS-02 is no
longer a COVERAGE gap (l0-static/tls-lifecycle-automated + l2-behavioral/
cert-lifecycle-automated both carry the label and main counts it covered), and the L0 check
is honest about the boundary in its own verdict line ("'revoked' is NOT proven at any
layer"). But the L2 test deletes a Certificate and requires its Secret to disappear, and
its failure message says "set enableCertificateOwnerRef: true ... (owner decision — WS-TEST
does not weaken the assertion instead)". That assertion is written to FAIL on a live run
until the owner decides. The decision is now arriving as a red test rather than as a
question, which is exactly how it gets weakened by whoever meets it next.
Two options are recorded verbatim for the architect, in the drafted preference order:
amend the requirement so revocation is an explicitly manual, documented break-glass action
(which also makes enableCertificateOwnerRef a CONSEQUENCE of the requirement), or keep the
text and record a reviewed DOCUMENTED_GAPS entry naming the clause, the reason and the
removal condition.
NOT APPLIED, and not appliable by an agent: the spec repo is read-only under R-TEST-06.
This is a request for a human decision, stated plainly as one.

fix(ci): the content scan could not match R-C2-01/02 — a digit in the workstream segment
Checked as part of closing the C2 coverage gaps, and it was live on main. The content
scan's pattern was `R-[A-Z]+-[0-9]+`, which CANNOT match an ID whose workstream segment
carries a digit: `[A-Z]+` consumes the `C` of `R-C2-01` and then demands a `-` where the
`2` is. `R-C2-01` and `R-C2-02` are the only two such IDs in
conformance/requirements/registry.yaml, and the scan was blind to BOTH.
REPRODUCED before the fix, on a throwaway repo whose only change is a manifest declaring
both IDs on real (non-comment) lines, in a path the map keys to nothing:
$ REPO_ROOT=$T BASE_REF=main ci/touched-requirements.sh
R-NET-06 # the all-letter control ID was the ONLY output
It failed by UNDER-attributing, which is the fail-OPEN direction: a change that retyped a
`conformance.home.k3s/R-C2-01` tag, or a manifest self-declaring R-C2-02, contributed
those IDs to NOBODY, so the C2 tests were filtered out of the merge gate. Same defect
class as the map's `*) : ;;` arm — a miss that reads as "nothing touched".
Every other consumer in the repo already allowed the digit, which is why this was the lone
dissenter: test_requirements_for_path() twenty lines above in this same script,
conformance/lib/coverage.py, conformance/lib/status.py and conformance/lib/
run_l1_offline.py all use `R-[A-Z0-9]+-[0-9]+`. Aligned to that form, with the reason
recorded at the line.
SCOPE OF THE HOLE. path_requirements() has no arm for platform/homepage/* or
platform/headlamp/* either, so before this the ONLY route to R-C2-01/02 was detection rule
3 (editing the C2 conformance test itself). No path-map arm is added here: c2-root-surface
declares `scope: whole-repo`, so ci/l0.sh Stage 3b's --include-scope union selects it on
EVERY gate invocation regardless of the touched set — which is the right mechanism for an
invariant whose input surface is the whole tree, and strictly stronger than a two-component
path arm would be.
REGRESSION-TESTED, in ci/tests/touched-requirements.test.sh (the suite `make -C ci test`
runs): a fixture declaring R-C2-01 / R-C2-02 / R-OBS-04 from `notes/` — a path outside
path_requirements(), so the IDs can only come from the content scan — asserts both digit
IDs ARE attributed, that the all-letter form still is (control), and that a purely numeric
workstream is not invented (the pattern must not widen the gate on noise).
PROVEN TO DETECT BREAKAGE: with the pattern reverted to `R-[A-Z]+-[0-9]+` the suite reports
`FAIL (2 failed, 14 passed)` naming both C2 IDs as missing; restored, all three ci/ suites
pass (16 assertions in this one).
ALSO: conformance/tests/l0-static/whole-repo-invariants-wired/check.sh cites this pattern
in the comment explaining why its BOGUS_REQ fixture is lowercase. Citation updated so the
reasoning still reads true; the fixture is unaffected (grep -E is case-sensitive, and the
check still passes 26/26).
NOTE: another branch may be editing this same script concurrently. This is a one-line
change to one statement plus its comment — expect a trivial conflict and keep the
`[A-Z0-9]` form.

fix(homepage): the C2 root hid a running service — Crafty had no tile
The R-C2-01 check added in the previous commit is RED on main for a real reason.
platform/crafty/httproute.yaml serves crafty.${BASE_DOMAIN} on the shared Gateway,
clusters/base/crafty.yaml reconciles it (dependsOn platform-config, wait:false), the web
UI is Keycloak-gated by a per-pod oauth2-proxy sidecar — and nothing on the operator's
front door linked to it. The service was running and the root did not admit it existed.
R-C2-01: "The root `home.keithjackson.dev` MUST serve a UI that surfaces the services
running in the cluster and links to them." An unsurfaced route is a requirement gap, not
a missing nicety, and it is the exact failure mode nothing else in the gate notices: every
cluster test stays green, the apex answers 200, and the estate is one service larger than
the dashboard says.
This is the SAME defect the unmerged 49c160d found on 2026-09-07 (feat/coverage-debt-
paydown, ~107 commits behind main). That branch was never merged, so the gap survived —
re-fixed here against today's tree, in token form (`crafty.${BASE_DOMAIN}`, not the
literal hostname that branch predated).
Grouped under Media because Crafty manages game servers; Platform would be equally
defensible and purely cosmetic. The tile also does duty for the L4 game ports
(crafty-mc.${BASE_DOMAIN}, TCP 25565-25567 / UDP 19132-19134), which have no browsable URL
of their own — the check reports those as an advisory rather than requiring a link.
ALSO: clusters/base/homepage.yaml's postBuild comment claimed "Homepage references no
${VARS} today; the substitution is retained for parity". That is no longer true and the
claim is dangerous, because it invites someone to delete the substitution as dead weight.
This component now references ${BASE_DOMAIN} in httproute.yaml's apex hostname AND in every
tile href; without substitution the token is applied literally, the apex route binds a host
matching no listener, every link on the root is dead, and Flux still reports Ready. Comment
corrected, and the property is asserted by c2-root-surface (5) so it cannot rot back.
Verified: conformance/tests/l0-static/c2-root-surface -> check OK, 49 assertions.

test(conformance): L0 covers R-C2-01 / R-C2-02 — 49 assertions, and it is RED
The Test DECLARATION landed in the preceding WIP commit with no check.sh, so the test
could not run at all. This is the check: 49 offline assertions over the repository as
git tracks it, no cluster, no network, no spec repo (R-TEST-06).
THE RULE. Every home-zone hostname the repository routes over HTTP must be linked from
the apex dashboard's configuration; every home-zone link the dashboard offers must
resolve to something the repository actually serves (an HTTPRoute at L7 or a
hostname-publishing LoadBalancer Service at L4); and the two R-C2-02 surfaces must be
linked, reconciled and backed by real alert rules, with operational rights arriving
per-user through OIDC groups rather than through a shared cluster-admin identity.
IT IS RED ON MAIN, on the forward direction:
FAIL (8) every service the repo ROUTES over HTTP is surfaced on the C2 root.
Unsurfaced: crafty.${BASE_DOMAIN} (platform/crafty)
platform/crafty/httproute.yaml serves crafty.${BASE_DOMAIN} through the shared Gateway,
clusters/base/crafty.yaml reconciles it, and nothing on the C2 root links to it. R-C2-01
says the root MUST surface "the services running in the cluster and links to them", so
an unsurfaced route is a requirement gap, not a styling preference. Fixed in the next
commit, deliberately separate so the RED is in the history.
WHAT IS ASSERTED BEYOND THE PRIOR ATTEMPT (49c160d on feat/coverage-debt-paydown, whose
tree is ~107 commits behind and was NOT merged):
(0) THE INPUT SURFACE ITSELF. The forward direction is only as good as the set of
manifests it reads, so three assertions guard the guard: the scanned roots are
present, every manifest in them PARSES (an unparseable file is a service the check
cannot see), and EVERY Flux-reconciled path lies inside a scanned root — so a
future tier reconciling, say, ./services fails loudly instead of letting the
dashboard hide all of it. conformance/ is deliberately excluded from the scan: its
fixtures and goldens declare synthetic HTTPRoutes (paas-demo, gw-declared-
conformance) that are test data, not services the cluster serves. The prior
attempt excluded them only by accident, through a filename prefilter.
(5) postBuild.substituteFrom ON THE DASHBOARD'S TIER. Hostnames are ${BASE_DOMAIN}
tokens now, not the literals the prior attempt compared. Without substitution the
apex route binds the literal host `${BASE_DOMAIN}` (matching no listener) and
every tile links to a host that does not exist — while Flux still reports the
Kustomization Ready. It fails OPEN, which is this repo's most-repeated incident
shape.
(12) TOKENS, NEVER LITERALS. No href may name a literal `home.keithjackson.dev` host,
so prod's front door cannot link dev's services — the 2026-09-04 class (two
clusters authored to describe the same names, prod's external-dns then deleting
dev's records), applied to the C2.
(2) THE SECTIONNAME IS PROVEN LOAD-BEARING rather than asserted from prose: the
wildcard listeners are shown to exist AND to be distinct from the apex listener,
which is why `*.${BASE_DOMAIN}` cannot serve the bare apex.
(10) THE REVERSE DIRECTION NOW ACCEPTS L4. The UniFi tile points at :11443 on a
hostname published by apps/vms/unifi/50-service-l4.yaml (a KubeVirt VM behind a
pinned Cilium LoadBalancer VIP). That is something this repo serves, so it
resolves — no off-cluster declaration is needed for it any more. The declaration
hatch is kept and constrained (specific home-zone hostnames, may not shadow a
hostname the repo does serve) but is EMPTY today, which is the honest state.
WHOLE-REPO SCOPE, as the declaration says. The invariant quantifies over every tracked
manifest that can declare an HTTPRoute; the change that BREAKS it is a route added
somewhere else entirely (`apps/wave-1/newthing.yaml` attributes R-GITOPS-02 or nothing,
never R-C2-01), and ci/touched-requirements.sh has no path-map arm for platform/homepage
or platform/headlamp at all. Requirement-scoped selection would filter this check out of
exactly the change that introduces the bug — the R-TEST-03 blind spot. No ci/l0.sh stage
is added: Stage 3b's --include-scope union selects it, and whole-repo-invariants-wired
fails the gate if anyone hand-adds one.
HONEST GAPS, in the check's own header: it does not fetch the apex (L2, covered for the
Gateway/TLS half under R-DNS-01 / R-TLS-01); (19) reads a DECLARED auth posture because
no Gateway ext-authz attachment exists anywhere in this repo, and says so in the
assertion text; it does not judge whether a tile is useful; and an L4-ONLY endpoint
(crafty-mc, a Minecraft game port) is reported as an ADVISORY rather than required,
because a raw TCP/UDP endpoint has no URL a browser can follow.

WIP: L0 test declaration for R-C2-01 / R-C2-02 (no check.sh yet)
INCOMPLETE — preserved by the PM after the authoring agent died to a server error mid-task (its third attempt; the first two died to a session rate limit). Do not merge. R-C2-01 and R-C2-02 are the only 2 remaining coverage gaps on main (49/51). This is the chainsaw Test declaration only: it quotes both requirements verbatim from the spec, cites docs/12-command-center-ui.md for which surface serves which half (Homepage at the root for R-C2-01, Headlamp for R-C2-02's 'controlled operational actions where safe', Grafana for dashboards/alerts), and argues why the deciding half is L0 rather than L2 — reachability is already covered by l2-behavioral/gateway-ingress-reachable, whereas whether the root surfaces THE SERVICES THE CLUSTER RUNS is a comparison of two sets that are both repository facts. WHAT REMAINS: check.sh does not exist, so this test cannot run at all. Also still open: whether 'a service the root hid' (from the prior art commit 49c160d on feat/coverage-debt-paydown) is still a live defect, whether ci/touched-requirements.sh can attribute R-C2-01/02 at all (a digit in the workstream segment reportedly broke the content scan), and the R-TLS-02 decision summary.

merge: Longhorn and cert-manager metrics exist now — 13 alerts were inert
Neither family was scraped at all, so every Longhorn alert (degraded, faulted, capacity) and every cert-manager alert (expiry, issuance) was structurally incapable of firing: storage health unmonitored on a cluster whose node just had a failing drive, TLS expiry unmonitored with the live wildcard cert 89 days out. Now proven on prod: longhorn_* 8717 series with longhorn-backend up=3, certmanager_* 104 series across 3 targets. Adds an L0 guard (118 assertions) that crosses from each alert rule to the scrape config and re-proves each enabling declaration against the working tree, including the negatives — cert-manager's monitor mutual-exclusion, the Longhorn metrics NetworkPolicy, and kube_node_labels needing metricLabelsAllowlist. Proven able to fail five ways. Hubble is deliberately NOT enabled: it opens 9965 on every cilium-agent and rolls the CNI DaemonSet across all three nodes, and platform/cilium carries an explicit parity contract with the Ansible template that a HelmRelease-only change would silently break. Registered as a declared gap instead. Two findings this surfaced, neither fixed here and neither absorbed silently: twelve apps/* <app>-down SLI rules discover zero targets because their ServiceMonitors name port 'metrics' and no app Service defines that port; and kube-state-metrics is OOMKilled roughly every ten minutes, making thirteen kube_* rules intermittently inert. |

test(l0): prove the dollar-collapse guard fires — and name the real envsubst
The implementation landed in the preceding WIP commit had never been executed. This finishes it: the arithmetic is re-measured, the guard and its allowlist are attacked, and the header's one factual error is corrected. WHAT ENVSUBST ACTUALLY IS. The header credited `github.com/drone/envsubst`. The pinned flux 2.4.0 binary in the dev image embeds `github.com/fluxcd/pkg/[email protected]` — Flux's own fork of drone/envsubst ("This package is a fork of drone/envsubst", its README) — read straight out of the binary with `grep -ao`. Same behaviour, different module; the header now says so and says how to check, because a claim about a dependency that nobody can re-derive is how the last wrong assumption survived. RE-MEASURED, NOT ASSERTED. Every row of the DOLLAR-RUN ARITHMETIC table was re-run through `flux envsubst` (flux 2.4.0, DEFINED=VALUE) and every row holds: `$$`->`$`, `$$$`->`$$`, `$${D}`->`${D}`, `$$${D}`->`$VALUE` (odd run: the brace is LIVE), `$$$${D}`->`$${D}`, `DO $$ x $$;`->`DO $ x $;`, and `$$${ARR[0]}` dies with "missing closing brace" while `$${ARR[0]}` is fine. `--strict` output was byte-identical to non-strict, exit 0 both ways (`cmp`) — strict mode is blind to this whole class, which is why a source assertion is the only guard available. The header now carries the 30-second reproduction, flagged to be re-measured on any FLUX_VERSION bump. END TO END ON THE REAL PATH. With the pre-16b7fcd manifest restored, `kubectl kustomize apps/wave-0` emits `DO $$` — valid SQL, and exactly what the `kubectl apply` verification saw — while the same stream through `flux envsubst --strict` emits `DO $` and `$;` and exits 0. That two-command contrast IS the incident. THE GUARD IS NOT TRIVIALLY SATISFIABLE — 16 adversarial cases, all as intended, run against a throwaway copy of the tree so nothing could be left behind: * an unmarked `$$` under a substituted path FAILS (DOLLAR-COLLAPSE); so do an odd `$$${...}` (DOLLAR-HALF-ESCAPED) and an even `$$$${...}` (OVER-ESCAPED); * a stale entry FAILS three ways — context no longer in the file, context that only covers an already-accepted `$${` escape and so excuses nothing, and a path that is not a file in the repo; * the allowlist cannot blanket-exempt a path: a 2-char context is rejected (<24), a `.*` wildcard is matched VERBATIM and therefore rejected as stale, a 24-char context carrying no dollar run is rejected, a 4-char reason is rejected (<40) — and, the central case, a genuine entry covers only the span its context matches, so a SECOND `$$` elsewhere in the same file still fails. Two genuine entries for two real occurrences do pass, so the mechanism is usable rather than merely unsatisfiable; * the CLASS, not the instance: the pre-fix `DO $$ ... $$;` reconstructed in a NEW ConfigMap under apps/wave-2 fails at both dollar runs, and restoring the real pre-16b7fcd apps/wave-0/nextcloud-db.yaml verbatim fails the check at lines 384 and 391. The guard rejects the exact commit that broke production. The scratch fixtures lived only in the throwaway copy; `git status` on this branch stayed clean throughout, which is the other half of the last attempt's unfinished business. LEGITIMATE USES EXIST AND STAY GREEN. 18 `$${...}` escapes (unifi cloud-init, the gitea and nextcloud OIDC bootstrap scripts, two longhorn comments) pass unremarked, and the 2 non-braced `$$` occurrences are the two allowlist entries. Those two are shell comments inside block scalars, and `kubectl kustomize` confirms the comment text really does survive into the stream envsubst reads — so they are genuine, reaching content whose collapse is cosmetic, not a hypothetical the allowlist was invented to excuse. STILL NOT PROVEN, AND STILL NOT PROXIED: that a change was verified through a substituting path. Which command a human ran is a fact about a shell session; git stores the manifest, never the invocation, so it is not statically decidable here and no honest formulation exists. Grepping commit prose for `kubectl apply` would be satisfiable by rewording and would fire on the break-glass runbooks whose whole content is that command. The answer is to move the proof off the verification path and onto the source, which is what assertion (7) does. No ci/l0.sh stage: the `conformance.home.k3s/scope: "whole-repo"` annotation is what wires it, and whole-repo-invariants-wired fails the gate on a hand-written stage.

merge: the gate no longer prints PASS when a stage did not run
ci/gate.sh set BLOCK=1 on a FAILED stage but only warned on a SKIPPED one, so it printed the words 'not green' and then 'MERGE GATE: PASS', exit 0 — fail open in the one component whose job is to fail closed. Observed live with prom-rules, and independently with l0 when the pinned kyverno CLI was absent. New contract: PASS/0 means every stage that was supposed to run ran and was green; BLOCKED/1 a failure or a must-run stage that did not; UNDETERMINED/3 nothing failed but greenness was not established; NOT APPLICABLE/0 unchanged. No knob inside gate.sh can turn UNDETERMINED into 0 — tolerating a non-answer is the caller's decision to make and to document. The distinction that makes it usable: a capability the environment DECLARES absent may still pass (no cluster, named in the headline); a stage that COULD NOT RUN may not. CI declares GATE_STRICT_SKIPS in the workflow rather than sniffing for CI, so a missing pinned tool there is exit 1. Carries over 47068ee's unusable-subset blocking from the unmerged fix/touched-requirements-fail-closed, now with tests. Measured its companion claim honestly: 159 of 613 paths (26%) are unmapped today, not 255 of 476 (54%) — 56 prose, 103 non-prose — which remains the larger fail-open and is recommended as its own change rather than smuggled in here. 47 assertions, 32 of which fail against the old gate.sh. |

feat(monitoring): scrape Longhorn + cert-manager — 8 alerts were structurally inert
An alert rule whose metric is never scraped is not a broken alert, it is an ABSENT
alert that reads as a present one. `longhorn_volume_robustness == 2` over a TSDB
with no longhorn_* series returns no vector: permanently quiet, permanently
"healthy", indistinguishable from a correct rule. It survives review (the PromQL is
right), it survives `promtool test rules` (the unit test supplies the series
itself), and it appears on no dashboard.
VERIFIED ABSENT ON PROD before this change (re-verified 2026-09-13 21:0xZ, ~15h
after the first audit, because a stale reading is not evidence):
count(longhorn_volume_robustness) => (empty) 4 rules inert
count({__name__=~"certmanager.*"}) => (empty) 3 rules inert
count(hubble_drop_total) / {__name__=~"cilium.*"} => (empty) 1 rule inert
count by (job) (up) => 20 jobs, none of them
Longhorn, cert-manager,
Cilium or Hubble
Consequence: storage health was unmonitored on the cluster whose prod-1 had just
had a failing SSD, and TLS expiry was unmonitored with the live `wildcard-home`
wildcard 89 days from expiry on an ACME DNS-01 renewal that can fail silently.
WHAT THIS CHANGES
* platform/longhorn: `metrics.serviceMonitor.enabled: true` (the supported chart
way — rendering longhorn 1.12.1 emits exactly 1 ServiceMonitor with the flag and
0 without), plus networkpolicy-metrics.yaml. The NetworkPolicy is LOAD-BEARING,
not belt-and-braces: measured with the monitor applied and no allowance, all 3
targets were DISCOVERED and every scrape failed `context deadline exceeded`
after 10.0s — a drop, not a refusal — while curling the endpoint from inside
the manager pod returned 200 in 0.031s. Longhorn 1.12.1 ships 6 NetworkPolicies
of its own, guarded on `networkPolicies.restrictInternalTraffic` (default TRUE)
and NOT on `networkPolicies.enabled`, so they are effectively unconditional and
the manager policy admits only same-namespace Longhorn components. The one-line
alternative (restrictInternalTraffic: false) was rejected: it deletes the
internal-traffic restriction across all six components to open one port to one
namespace, trading an R-SEC-02 control for an observability one when the two do
not conflict. This policy is Ingress-only, ns monitoring -> app=longhorn-manager,
TCP 9500 only; 9502/9503 (webhook, recovery backend) stay closed.
* platform/cert-manager: `prometheus.servicemonitor.enabled: true`. Chart default
already serves 9402; only the monitor was missing. No NetworkPolicy needed —
neither ns cert-manager nor ns monitoring carries one. NOT paired with
prometheus.podmonitor.enabled: the chart calls `fail` if both are set.
* platform/kubevirt: KubeVirtVMLaunchFailing queried
`kubevirt_vmi_phase_count{phase="Failed"}`, which DOES NOT EXIST on the deployed
KubeVirt — a different flavour of the same defect, with the scrape target up and
healthy. Prod has only `kubevirt_vmi_info` and `kubevirt_vmi_number_of_outdated`;
the only phase-bearing names are the phase_transition_time histograms. Corrected
to `kubevirt_vmi_info{phase="failed"}` — LOWERCASE, because KubeVirt lowercases
the value (observed `phase="running"` for the unifi VMI) and a capital-F matcher
would select nothing and be exactly as inert.
PROVEN, NOT ASSERTED. The rendered ServiceMonitors were applied to prod by hand and
the metrics observed to land, then REMOVED again so the merge's Helm upgrade creates
and owns them rather than colliding with an unowned object:
count(up{job="longhorn-backend"}) => 3 (all three managers, up==1)
count({__name__=~"longhorn.*"}) => 8717 (was empty)
count(longhorn_volume_robustness) => 44
up{namespace="cert-manager"} => 3 targets, all 1
count({__name__=~"certmanager.*"}) => 104 (was empty)
wildcard-home days to expiry => 89.2, ready_status{condition="True"}=1
All 58 alert rules in the repo were then evaluated against prod one by one: every
one returns a result without error, and exactly ONE fires.
TRIAGE OF THE ONE NEWLY-FIRING ALERT — A TRUE POSITIVE, NOT TUNED AWAY.
LonghornVolumeCapacityHigh on the Prometheus TSDB volume:
`longhorn_volume_actual_size_bytes / longhorn_volume_capacity_bytes` = 0.971
(48.6 GiB allocated of 50 GiB) while the kubelet's view of the same filesystem is
only 20.4% used. Longhorn is not reclaiming freed blocks, so ~48.6 GiB x 3 replicas
is committed for ~10 GiB of real data. On a cluster whose failure mode is disk
pressure and whose etcd WAL shares a spindle with Longhorn, that is worth knowing
and was invisible until now. The threshold is left alone; the follow-up is
filesystem trim, not a bigger number.
THE GUARD (conformance/tests/l0-static/alert-metrics-have-scrape-targets)
Whole-repo L0 invariant, 118 assertions. It crosses from each alert to the scrape
config that makes its metric exist: every metric name is claimed by exactly one
declared owner, and each owner's enabling declaration is re-proven against the
working tree on every gate run, including the negative conditions that defeat an
enablement without deleting it. `up{job="X"}` is audited on its own axis, because
`up` always exists: where this repo authors a Service and a ServiceMonitor in the
same file, the monitor's endpoint port must be a port that Service defines.
It DECLARES conformance.home.k3s/scope: "whole-repo" and adds NO ci/l0.sh stage —
the whole-repo-invariants-wired meta-test fails the gate if one reappears.
PROVEN ABLE TO FAIL, five ways, each reverted:
1. an alert on a fabricated metric -> FAIL "claimed by NO entry"
2. longhorn metrics.serviceMonitor removed -> FAIL "no longer matches"
3. networkpolicy-metrics.yaml unwired -> FAIL "the monitor alone is NOT enough"
4. cert-manager podmonitor also enabled -> FAIL "FORBIDDEN pattern"
5. a register entry made stale / removed -> FAIL in both directions
TWO SHRINK-ONLY REGISTERS, because a blanket fail would make the gate red until
work that is not this change lands, and a disabled gate protects nothing:
* KNOWN_UNWIRED_METRICS (1): hubble_drop_total. See below.
* KNOWN_UNWIRED_JOBS (12): every apps/* `<app>-down` SLI rule is ALSO inert, and
this was found by the re-audit, not previously known. The rendered
ServiceMonitors name `port: metrics` and NOT ONE of the twelve app Services
defines a port of that name (zero occurrences of `name: metrics` across all
twelve manifests); prod confirms none of the twelve jobs appears in `up`. This
is the nastiest variant of the class: `up` exists in abundance so nothing looks
wrong, and PrometheusTargetsMissing cannot see it either, because a target that
was never discovered has no up series to be 0. Closing it needs an exporter per
app (Plex, Pi-hole, Jackett, qBittorrent, Sonarr, Radarr, Seerr speak no
Prometheus) — except keycloak, where the live jobs are keycloak-service /
keycloak-discovery and the rule is a rename away from being live.
NOT DONE HERE, DELIBERATELY: Hubble. hubble.metrics.enabled RECONFIGURES THE CNI —
it opens 9965 on every cilium-agent and rolls the DaemonSet across all three nodes,
serialised by this repo's own maxUnavailable: 1 (set after the 2026-09-01
k8sServiceHost outage, where a CNI roll deadlocked 2 of 3 agents). It also needs a
matching edit to roles/cilium/templates/cilium-values.yaml.j2 in the same commit,
because platform/cilium/helmrelease.yaml carries a [parity] contract against it and
a rebuilt node would otherwise bootstrap a CNI config that disagrees with the
reconciled one. Recommended as its own change on the cilium Kustomization, with the
Ansible parity edit, a narrow labelsContext, and a one-node canary — not smuggled in
here.
ALSO FOUND, NOT FIXED HERE: kube-state-metrics is OOMKilled every ~10 minutes on
prod (90 restarts in 16h against a 128Mi limit) while its logs show the
custom-resource-state factory reloading every 3 seconds. Thirteen alert rules read
kube_* metrics, so those rules are INTERMITTENTLY inert — the same defect class,
arriving through a crashloop rather than a missing monitor. Needs its own change.

fix(ci): SKIPPED is not green — the gate can no longer PASS on a stage that did not run
Completes the WIP preserved in the previous commit. `MERGE GATE: PASS` + exit 0 now means
what it says: every stage that was SUPPOSED to run ran, and was green.
THE DEFECT. In gate.sh's decision section a FAILED stage set BLOCK=1 but a SKIPPED stage only
warned, so the gate printed `l0: skipped (unwired seam / missing tool) — not green` and then
`MERGE GATE: PASS`, exit 0. Seen twice for real: `prom-rules` skipped because promtool was
absent, and `l0` skipped because the pinned kyverno CLI was. Exit 0 is what CI and every
`||`-chained script read as merge-approved, so the one component whose entire job is to fail
closed was failing OPEN — in a repo whose stated principle is that SKIPPED IS NOT GREEN, and
whose history already contains the 2026-08-31 "local false green" that UNDECIDED was added to
prevent. The offline stages simply never used that vocabulary.
A SKIP IS NOT ONE THING — the per-stage rule, with the justification in the file header:
* lint / l0 / render-golden / l1 — COULD NOT RUN (a pinned tool absent, a seam unwired).
BLOCKED under strict skips (a CI runner has the toolchain installed for it by
install-tools.sh, so a skip there is a defect); UNDETERMINED (exit 3) otherwise — a
workstation missing a tool is a real local condition, still non-zero, still never a pass.
* spec-immutability — the spec repo is not checked out, so R-TEST-06 COULD NOT BE VERIFIED:
UNDETERMINED. Deliberately NOT upgraded to a block by strictness, because the live runner
does not check the spec repo out at all and blocking would leave the only enforced status
check permanently red for a reason no PR can clear. It is the ONE skip a caller may
knowingly tolerate; REQUIRE_SPEC_VERIFICATION=true makes it hard once wired.
* conformance L2/L3 — CLUSTER_AVAILABLE!=true is the environment DECLARING the capability
absent, not a stage failing to run where it could have. A declared-inapplicable stage was
never "supposed to run", so it does not deny a PASS — but it is now NAMED in the PASS
headline and the step summary, so PASS never implies more than was verified. A skip
DESPITE CLUSTER_AVAILABLE=true still blocks.
declared-not-applicable may pass; could-not-run may not.
STRICTNESS IS DECLARED, NOT SNIFFED. .gitea/workflows/gate.yml sets GATE_STRICT_SKIPS=true on
the gate step — the workflow is the thing that knows it is CI — with GITHUB_ACTIONS/CI (set by
the runner itself) only as the `auto` fallback. No hostname/path/tool-availability heuristic.
A wrong answer in either direction cannot fail open: both branches are non-zero and neither is
a PASS. That step now calls ./ci/gate.sh directly and tolerates exit 3 in one visible line,
because under strict skips exit 3 can ONLY mean the unverifiable spec repo — a missing tool is
exit 1 and untolerated. Tolerating a non-answer is a reviewed choice in the CALLER; there is
deliberately no knob inside gate.sh that turns UNDETERMINED into exit 0.
ALSO, from the unlanded fix/touched-requirements-fail-closed (47068ee), whose reasoning is
carried over rather than its tree: gate.sh special-cased only exit 3 from
touched-requirements.sh, so ANY other non-zero exit left the touched set empty and printed PASS
having applied no coverage gate at all. An unusable subset is not an empty subset: it BLOCKS.
Latent today (the script exits only 0 or 3) and wired now so the hole is already closed when a
fail-closed path map makes exit 1 reachable — the measured state of that map is in the PM report.
TESTED — ci/tests/gate-decision.test.sh, 47 assertions over the whole decision table: the real
gate.sh and lib.sh run in a throwaway CI_DIR against STUB stage scripts whose exit codes the
suite dictates, so it asserts how the gate REASONS, with no tools, no cluster, no network. All
stages green -> PASS/0; each stage FAILED -> BLOCKED/1; each stage SKIPPED -> never PASS and
non-zero; strict skips -> BLOCKED/1; the spec exception; the declared-gap PASS; the
undetermined-touched-subset paths unchanged (on-base -> NOT APPLICABLE/0, no-base and
diff-failed -> BLOCKED/1); UNDETERMINED outranking NOT APPLICABLE; an unusable subset ->
BLOCKED/1; truthy()'s misspelling direction. 32 of the 47 FAIL against the pre-change gate,
including "l0 SKIPPED: printed 'MERGE GATE: PASS'" — the suite is falsifiable, not decorative.
lib.sh: truthy() is now the one spelling of "is this switch on" and cluster_available() uses it
(the comment claimed that; now it is true), and load_touched_requirements' rc!=0 branch says
what actually happened instead of "proceeding with the full layer".

WIP: catch envsubst collapsing a doubled dollar in substituted paths

WIP: the gate must not print PASS when a stage was skipped
INCOMPLETE — preserved by the PM after the authoring agent hit the session
rate limit mid-task. Do not merge without finishing and gating it.
Problem: in ci/gate.sh a FAILED stage sets BLOCK=1 but a SKIPPED stage only
warns, so the gate prints the words 'not green' and then concludes
'MERGE GATE: PASS' and exits 0. Observed live tonight with prom-rules, and
independently with l0 when the pinned kyverno CLI was absent. That is
fail-open in the one component whose whole job is to fail closed.
The agent was mid-way through adding truthy/strict_skips helpers to ci/lib.sh.
WHAT REMAINS:
- Per-stage justification for which skips must BLOCK and which may degrade
to a non-zero UNDECIDED (spec-immutability and L2/L3 skip for legitimate
environmental reasons and must stay usable locally).
- Whether CI and local can be distinguished reliably here.
- New ci/tests/ suite for the decision logic, and a before/after proof.
- Reconciling with the unmerged branch fix/touched-requirements-fail-closed,
whose 47068ee already makes an unusable touched subset block, and whose
56c242d claims 255 of 476 paths were unmapped in the path->requirement
map — a far larger fail-open that still needs measuring on current main.

WIP: durable qBittorrent WebUI credential
INCOMPLETE — preserved by the PM after the authoring agent hit the session
rate limit mid-task. Do not merge without finishing and gating it.
Problem: qBittorrent 5.1.2 has no WebUI\Username or WebUI\Password_PBKDF2 in
its config, so it mints a NEW temporary admin password on every process start
and announces it only on stdout. Two consequences, both real: the Sonarr and
Radarr download clients configured earlier will silently stop working at the
next pod restart, and a human operator has no stable login either.
Adds a SOPS-encrypted qbittorrent-bootstrap Secret (verified encrypted: both
values are ENC[AES256_GCM]) plus the catalog/rendered wiring to consume it.
WHAT REMAINS:
- The agent's last note: the postStart hook works, but its output never
reaches kubectl logs, so it was switching to the marker-file logging
pattern gitea's hook already uses. That change is NOT here.
- The Secret exists on prod as kubectl-client-side-apply, i.e. live-only;
merging adopts it into git.
- Sonarr's and Radarr's stored download-client passwords were to be updated
to the durable value — NOT done, so the chain may break on restart until
it is.
- The required proof is unfinished: restart the pod, then show the WebUI
accepts the credential AND both arrs still report isValid: true.

feat(monitoring): scrape the Flux controllers — five gotk_* alerts were inert
kube-prometheus-stack does not scrape flux-system: the controllers are
bootstrapped, expose no Service, and no chart value covers them. So every
gotk_* alert rule in platform/monitoring/alerts.yaml could never fire —
verified on prod, count({__name__=~"gotk.*"}) returned nothing. A repo whose
entire delivery model is Flux had no alerting on reconciliation failing, a
Kustomization erroring, or a resource left suspended.
Proven live before landing: with this PodMonitor applied, gotk_suspend_status
returns 39 series and gotk_reconcile_condition 117, and FluxResourceSuspended
actually fired on a deliberate test suspension — evidence the rule is live,
not merely present.
Extracted from the wider inert-alert audit on
fix/scrape-targets-for-inert-alerts, which stalled unfinished. This is the
self-contained, verified half; Longhorn and cert-manager metrics are still
ABSENT and their alerts remain inert. It also adopts the object into git: it
existed on prod only as kubectl-client-side-apply, so a rebuild would have
lost it.

fix(cnpg): the grant reconciler died on every Flux-managed run
The SQL asserted convergence in a dollar-quoted PL/pgSQL DO block. That cannot survive this delivery path: the ConfigMap is rendered through Flux's postBuild substitution, and envsubst collapses a doubled dollar into one, so Postgres received a half-quoted DO and failed with a syntax error. Three scheduled runs had left nine Error pods in nextcloud-db. It passed verification because it was hand-applied with kubectl, which runs no envsubst — the defect only existed once Flux owned the object. The GRANT on the first line still succeeded, so the privilege held and the blind spot stayed closed; what was broken was the assertion meant to prove it, which is the part that makes a silent regression visible. Rewritten in plain SQL with no dollar sign anywhere in the file, comments included. Escaping by doubling again would also work and would be the next person's trap. has_database_privilege()::int is 1 or 0, so the division raises division_by_zero and ON_ERROR_STOP=1 fails the Job; the divisor is not constant so it cannot be folded away at plan time.

merge: the placeholder guard test was hiding a RED, not a pass
It had been permanently SKIPPED because it expected bootstrap/standup.sh, which never landed on main — planned, never merged, still living only on the unmerged prod-standup branches along with the 2026-09-05 incident it came from. Dropping the real script in and running the old check produced FAIL 2/34: it would have false-blocked the very merge that landed its own input. Now split into the half that needs no guard (no overlay ships a placeholder-shaped effective cluster-vars value; an empty value must be STATED by the overlay, not inherited in silence; a loud base sentinel must be explicitly overridden) and the half that self-activates. The guard is discovered by CONTENT — any tracked *.sh defining <name>_is_placeholder() — so landing one anywhere activates the second half with no edit here, and two definitions is a failure. The check never exits 3 again. Unscoped L0 goes 13 PASS / 1 SKIP -> 14 PASS / 0 SKIP. |

merge: 35 runbooks, served, with a guard that they resolve
All 46 runbook_url annotations pointed at https://<apex>/runbooks/<name> and every one returned 404 — there was no runbooks/ directory and no route. Every alert that reached a human handed them a dead link at the moment they needed it. Runbooks are now served from their own non-gating tier at the apex prefix, PUBLIC on purpose: gating them behind Keycloak would make keycloak-down unreadable exactly when Keycloak is down, which is a loop with no exit. The new L0 guard checks both directions — a runbook_url with no file, and a file not wired into the generator — and it caught a live one on contact with main: CNPGPrimariesCoLocated had shipped hours earlier pointing at a runbook that did not exist. |

merge: promtool is in the toolchain, so the alert unit tests actually run
324 lines of mutation-checked promtool tests had landed with nothing to
execute them: promtool was not in the pinned toolchain, so the coverage was
present and enforced by nothing — the failure mode this repo keeps hitting.
promtool 3.14.0 is now pinned in both versions.env files (matching prod's
Prometheus, verified against the running image) and baked into the
container. The two competing harnesses are consolidated into one, and the
two competing wirings into one: the bespoke ci/prom-rules.sh stage is
deleted in favour of a scope-declaring conformance test, because a
hand-written stage running one hardcoded script is exactly the pattern

fix(conformance): placeholder-guard-coupling actually RUNS — it was skipping forever
`conformance/tests/l0-static/placeholder-guard-coupling` (R-ENV-02, R-STATE-03) exited 3 SKIPPED on every gate run since it landed, because its check keyed its whole existence on `bootstrap/standup.sh`. Measured, not assumed: that file has NEVER been on `main` — there is no deletion commit for it anywhere; it landed only on unmerged prod-standup branches (`work/prod-standup-campaign`, `prod/*`, `feat/prod-hardening`). It was planned and never merged, not removed. SKIPPED is not green, and a permanently-skipped incident-derived test is the quiet version of the failure it was written to prevent. The skip was also hiding a RED. Run against the real `standup.sh` from `work/prod-standup-campaign`, the old check FAILED 2 of 34 assertions — false positives from treating the empty string as placeholder-shaped for knobs cluster-vars authors empty on purpose (`BACKUP_CREDENTIALS_SUFFIX`, `VELERO_BACKUP_PREFIX`, both `""` on dev and both documented there as load-bearing). It would have false-blocked the merge landing its own input. NOT deleted — the hazard is not gone. Split into two halves, one of which needs no guard: HALF A (always runs): no environment overlay ships a placeholder-shaped EFFECTIVE cluster-vars value; an empty effective value is STATED by the overlay rather than inherited in silence; a LOUD base sentinel is explicitly overridden by every overlay. This is the 2026-09-05 outcome asserted at the source instead of at the guard — if prod's S3_BACKUP_ENDPOINT is never a placeholder, velero cannot be pointed at a hostname that does not exist. Input surface is `clusters/`, all of it on `main`. HALF B (self-activating): the real predicate extracted and executed against those same values, the consumer trace, and the mid-string anchoring property. The check NEVER exits 3 again, and the guard is DISCOVERED by content rather than hardcoded: any tracked `*.sh` defining `<name>_is_placeholder()` is found, so a guard landing at `bootstrap/standup.sh` — or moved into a sourceable library, the remedy the check already recommends — activates HALF B with no edit to the test. Two files defining it is a FAIL. When no guard exists the gap is printed loudly every run instead of swallowed as a skip. LOUD vs EMPTY is the correction that makes it honest in both modes: a loud placeholder is always a defect in an overlay, while `""` is held to the explicitness rule instead — and still counts as a placeholder for a knob a guard covers, because a `""` case-arm is the guard author's declaration that empty is not a usable target. Proof, all reverted: 84 assertions and exit 0 on `main`; prod S3_BACKUP_ENDPOINT set to the literal `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com` FAILS (A1); deleting dev's explicit VELERO_BACKUP_PREFIX op so it inherits `""` FAILS (A2); a LOUD base BULK_NFS_SERVER with prod's override deleted FAILS 2/86 (A1+A3); and with the real `standup.sh` present, reverting `s3_is_placeholder` to the `TBD-*` PREFIX glob FAILS 12/110 (B3 anchoring). With the pristine `standup.sh` the check PASSES at 110 assertions where the old one failed 2 of 34. L0 layer: 14 checks, 14 PASS, 0 SKIP, 0 FAIL (was 13 PASS / 1 SKIP). Coverage unchanged — R-ENV-02 and R-STATE-03 both still list this test, 49/51 with the same 2 gaps. Also: * `ci/touched-requirements.sh` — `bootstrap/*` -> R-STATE-03 R-GITOPS-01 is KEPT, its stale comment corrected. It claimed standup.sh "carries the placeholder guards", describing a file that is not here; R-STATE-03 there is ANTICIPATORY. Deleting the entry would leave the change that lands a placeholder guard selected by nothing. * `ci/tests/touched-requirements.test.sh` — new path-map section (12 assertions, was 8) locking `bootstrap/*` and `clusters/*`, so removing either entry is a test failure rather than a silent loss of selection. All three ci/tests pass (12 + 31 + 15). * `docs/BULK-NFS-STORAGE.md` §7 — its "nothing in the gate currently refuses a placeholder-shaped overlay value" is no longer true; corrected. * Scope re-audited: still deliberately requirement-scoped, not whole-repo. Every path that can break it attributes a requirement it declares. Co-Authored-By: Claude Opus 5 <[email protected]> |

docs(runbooks): forward-auth IS enforced — correct the posture note
The serving route's comment claimed that because no Gateway ext-authz attachment exists, every forward-auth route is 'in practice reachable unauthenticated today'. That is wrong, and wrong in a dangerous direction for a document an operator reads during an incident. Enforcement here is PER-POD, not gateway-level: each of the five services declaring auth: forward-auth (pihole, jackett, qbittorrent, radarr, sonarr) publishes both its app port and 4180 on its Service, and its HTTPRoute targets :4180 — the oauth2-proxy sidecar. Verified on prod. The app port remains reachable in-cluster on purpose, which is how sonarr/radarr drive qBittorrent's API, and Cilium default-deny governs that path. The public-by-design decision for this route is unchanged and still correct; what changes is that it is genuinely the exception rather than one open route among many. Headlamp's exclusion is likewise deliberate (native OIDC with per-user id_token forwarding and no ServiceAccount cluster rights). Co-Authored-By: Claude Opus 5 <[email protected]> |

feat(ci): promtool in the pinned toolchain, one alert-rule harness, and the gaps declared
The CNPG alert unit tests (324 lines, mutation-checked) were run by NOTHING. promtool was
not in the baked toolchain, no gate stage evaluated any *.promtool-test.yaml, and the only
runner `curl | tar -xz`'d a promtool release from GitHub at TEST-RUN time if one was
missing. Hours later a second, independent harness landed for the Velero rules
(platform/monitoring/tests/) with its own fallback — a `podman run` of
quay.io/prometheus/prometheus. So the repo had two harnesses, two acquisition paths, and
coverage that looked present and was enforced nowhere: the exact failure mode that had just
produced a permanently-firing CNPG alert and a structurally inert Velero alert.
PROMTOOL IS NOW PINNED LIKE EVERY OTHER TOOL. PROMTOOL_VERSION=3.14.0 in
infra/devcontainer/versions.env and ci/versions.env (the two stay in lockstep, per the
repo's rule), baked by the Containerfile from the prometheus release tarball (promtool ships
inside it), recorded in /etc/dev-toolchain-versions, passed by dev.sh, and installed for the
l0 stage by .gitea/workflows/scripts/install-tools.sh so the CI runner is not permanently
SKIPPED. The pin is not free-floating: promtool IS the rule engine, so it tracks the
Prometheus prod actually runs — verified against the live cluster, not assumed:
kubectl --context k3s-prod get prometheus -n monitoring -o jsonpath='{.items[*].spec.version}'
-> v3.14.0-distroless (image quay.io/prometheus/prometheus:v3.14.0-distroless)
ONE HARNESS. platform/cnpg/run-alert-tests.sh is folded into
platform/monitoring/tests/run.sh, which now covers every PrometheusRule in the repo that has
tests, via two conventions it discovers automatically: `<manifest>.promtool-test.yaml`
beside its manifest (cnpg), and `<component>/tests/*.test.yaml` over that component's
manifests (monitoring). It writes the flattened rules under whatever name each test file's
own `rule_files:` declares, so no test file needs to know the harness exists, and it
`promtool check rules` first — a rules file that does not parse would make every unit test
pass vacuously by finding no rules at all. The cnpg script's reasoning is preserved: why a
CR must be flattened (`.spec.groups`, never re-typed), and why generated files go to a temp
dir. Its `${BASE_DOMAIN}` substitution is dropped in favour of extract_rules.py's verbatim
placeholders, with the trade-off recorded there — the hazard it guarded against is addressed
by the temp dir, and verbatim leaves one transformation fewer between the shipped rule and
the rule under test.
NO ENGINE IS ACQUIRED AT RUN TIME any more — not the GitHub release, not the container
image. Not because a pinned download is unusual here (the Containerfile downloads every tool
it bakes) but because those two decided the version, the network and the machine SILENTLY,
at test time, on whatever host ran the tests; and each quietly turned "the toolchain has no
promtool" into a green run, which is how the toolchain stayed without one. Missing promtool
is exit 3 (UNWIRED, never green); a PROMTOOL= that does not resolve is exit 2.
ONE WIRING: conformance/tests/l0-static/alert-rules-unit-tested, NOT a gate stage. The
`prom-rules` stage (ci/prom-rules.sh + its Makefile target + ci/gate.sh entry) is deleted:
it is the bespoke-per-check pattern

merge: the arrs had no download client at all, and now agree on paths
Investigating the path disagreement found the larger defect: sonarr and radarr each returned [] from /api/v3/downloadclient — Completed Download Handling had never been wired up, not merely broken. Both now have qBittorrent configured plus a remote path mapping /downloads/ -> /media/downloads/, proven with a real completed torrent and a negative control: same torrent, same client, mapping absent gave an unresolvable /downloads/... and mapping present resolved the real file at inode 36144. This state lives in each arr's database, NOT in git — a rebuild from git does not restore it. Recorded in DECISIONS-LOG with the recommendation to close it properly via path agreement instead. |

fix(runbooks): declare whole-repo scope, drop the bespoke l0 stage, +cnpg-primary-spread
Three corrections after rebasing onto main. 1. THE GUARD CAUGHT A REAL ONE ON ITS FIRST CONTACT WITH main. main had gained `CNPGPrimariesCoLocated` (platform/cnpg/alerts.yaml) pointing at /runbooks/cnpg-primary-spread, with no runbook. The check failed the rebase exactly as designed — 46 annotations, 35 names, 34 present — naming both the missing file AND the missing configMapGenerator entry. runbooks/cnpg-primary-spread.md now exists: what co-located primaries actually cost here (blast radius, not an outage, because instances: 3 + required anti-affinity), why the drift is uncorrectable-by-declaration (CNPG has no primary-placement field), the readiness gate that keeps the rule quiet during a real node outage, and the ~9s-per-database switchover rebalance, one cluster at a time. The 2026-09-07 outage in which all three primaries sat on one node is the reason the alert exists at all. 2. WHOLE-REPO SCOPE, NOT A HAND-WRITTEN STAGE. main's refactor replaced ci/l0.sh's per-check "UNCONDITIONAL" stages with a declaration: `conformance.home.k3s/scope: "whole-repo"`, unioned into every gate run by Stage 3b's `--include-scope`. My +38-line Stage 3f is removed (ci/l0.sh is now byte-identical to main) and the annotation is declared instead. Assertion (7) of the check was rewritten to match: it no longer asserts its own path appears in ci/l0.sh — it asserts the test DECLARES the scope and that ci/l0.sh still passes --include-scope, since neither half alone makes the check load-bearing. That matters here because ci/touched-requirements.sh maps platform/monitoring/* to "R-OBS-01 R-OBS-02", not R-OBS-04, and maps platform/kubevirt/* and runbooks/* to nothing at all. 3. A FACTUAL CORRECTION IN ALL 35 RUNBOOKS. Every page claimed `dev.sh` defaults its current-context to k3s-dev. main's `9b4744d fix(devcontainer): dev.sh defaults to prod` made that false, and a runbook that misstates which cluster a command talks to is worse than one that says nothing. The pages now say what is durably true: the default has already changed once, so naming `--context k3s-prod` is what makes a command mean the same thing next month, and the per-invocation banner is there to be read. The check's own failure message was corrected the same way. Re-verified after all three: check green at 374 assertions (46 annotations, 35/35 runbooks present, 35/35 projected), re-applied to prod, and re-probed in-cluster through the Gateway — node-down, keycloak-down, keycloak-client-secrets, cnpg-archiving, longhorn-faulted, vpn-down, node-io and cnpg-primary-spread all HTTP 200 with text/plain; charset=utf-8 and 8.9-12.1 KB of real body; /runbooks/ index 200; an unknown name 404s with a pointer rather than a blank page; and homepage still answers the apex `/`, confirming Gateway API longest-path precedence. Full merge gate: PASS (spec-immutability, lint, l0, render-golden, l1 all green; prom-rules SKIPPED for want of promtool in the image; L2/L3 SKIPPED, no cluster).

fix(arr): wire qBittorrent as a download client + Remote Path Mappings
qBittorrent reports finished releases at /downloads/<name>; sonarr and radarr
see the same inodes at /media/downloads/<name>, so Completed Download Handling
could never resolve what the client handed it. Configured, on prod, via each
app's own HTTP API:
* download client qBittorrent -> qbittorrent.qbittorrent.svc.cluster.local:8080
(it did not exist in EITHER arr: both /api/v3/downloadclient returned [])
* Remote Path Mapping /downloads/ -> /media/downloads/ for that host
Both built from each app's /downloadclient/schema, matched on identity before
writing, and re-running creates nothing. downloadclient/testall reports
isValid=true in both. Proven with a negative control: Sonarr's queue showed
outputPath=/downloads/... with the mapping deleted and /media/downloads/...
with it present, for the same completed torrent.
This state lives in sonarr.db / radarr.db on the config PVCs, NOT in git — a
rebuild from git alone does not restore it. Recorded as a wart, with path
agreement (repointing SavePath to /media/downloads) recommended as the durable
fix and put to the operator rather than taken unilaterally.

feat(runbooks): make the 42 alert runbook_url annotations resolve
Every platform-health alert rule carries `runbook_url: "https://${BASE_DOMAIN}/runbooks/<name>"` — 42 annotations over 34 distinct names, across platform/monitoring/alerts.yaml, platform/monitoring/pvc-capacity-alerts.yaml, platform/cnpg/alerts.yaml and platform/kubevirt/alerts.yaml. There was no runbooks/ directory and no HTTPRoute serving that path: an in-cluster probe of https://home.keithjackson.dev/runbooks/node-down returned HTTP 404. Every alert that reached a human handed them a dead link at the exact moment the documentation is read, and the annotation made it look solved — the same green-surface-over-absent-mechanism class as the import Job that reported success while storing placeholder secrets. No alerts.yaml is touched and no runbook_url value changes. The existing URL scheme is made to resolve instead. WHAT LANDS - runbooks/<34>.md — one per name, each grounded in this cluster's real topology and, where one exists, its real incident history: the 2026-09-07 k3s-prod-1 etcd I/O starvation (measured PSI 11.36 vs 0.75/1.29, the exact journal lines, the four mechanisms proven inert), the Longhorn reboot tax and the freeze/thaw of concurrent-replica-rebuild-per-node-limit, Cilium's once-resolved egress interface cache (Ifindex 3 against a live 1780) and the absence of OSS failover, the CNPG 38-hour ContinuousArchiving=False with its measured 6.8 MiB/h disk-full clock and the 2026-09-12 aggregation-scope fix, the 2026-09-06 Keycloak lockout in which all 12 clients held literal placeholder secrets behind an entirely green cluster, the Velero R2 x-amz-tagging NotImplemented incompatibility and its v1.14.3-rc.2 pin, and swap re-enabling itself across reboots via systemd-gpt-auto-generator. Each page states what the alert means HERE, the first diagnostic commands, likely causes ordered by probability with a remediation each, and when to escalate or stop. - Every page uses FULLY-QUALIFIED resource names and says why: three CRDs register the kind `Backup` here, the bare short name resolves to Longhorn's (zero objects), so `kubectl get backup -A` prints "No resources found" on a cluster holding 6 Velero and 27 CNPG backups. Acting on that false negative is how a CLI quirk becomes data loss. - Every page states that kubectl only works via `infra/devcontainer/dev.sh run bash -c '...'` with an explicit `--context k3s-prod`, because dev.sh defaults its current-context to k3s-dev. - Pages also record which alert groups are INERT today (measured 2026-09-13: no Longhorn, cert-manager, Flux-controller or Hubble scrape job exists, so 13 rules evaluate against nothing) so nobody reads their silence as health. SERVING — runbooks/serving/ plus clusters/base/runbooks.yaml A two-replica nginx-unprivileged serving a ConfigMap generated from runbooks/*.md, at the apex `/runbooks` prefix, in its own non-gating post-platform Flux tier (dependsOn platform-config, wait:false) — the platform/homepage pattern, file for file. - The service catalog cannot express this route: ingressRoutes[].host is pattern-bound to a single DNS label plus the apex, so the bare apex is unrepresentable, and there is no path field. - Rejected: redirecting to the Gitea web UI. A runbook is read when the platform is broken, and Gitea is an app-tier workload whose own dependencies several of these runbooks document; Gateway API's RequestRedirect also has no "append .md" modifier, so it would need 34 hand-maintained ReplaceFullPath rules. - configMapGenerator maps each file to an EXTENSIONLESS key (node-down=node-down.md), so /runbooks/node-down is a plain static lookup with no rewrite rule.

merge: alert when a backup schedule has NEVER run, and when one is paused
VeleroNoRecentBackup could not see the failure that actually happened:
velero-daily sat paused having never produced a successful backup, so
velero_backup_last_successful_timestamp{schedule=...} did not exist and
time() - <absent series> yields no series. Prod had no volume backups and
nothing alerted, further masked by a resources-only schedule succeeding
daily. No velero_* metric describes a Schedule OBJECT, proven by scraping a
throwaway paused Schedule and finding zero lines, so this exposes the CRs
via kube-state-metrics customresource_state and keys on
defaultVolumesToFsBackup — the property, not a name list. Adds the repo's
first prometheus rule-unit-test harness, mutation-checked both ways.

merge: whole-repo L0 invariants are DECLARED, not hand-wired per test
The gate had been accreting one bespoke UNCONDITIONAL stage per whole-repo L0 test (3c/3d/3e), each repeating the same ~12-line rationale and each one something the next author had to remember to write. Forget it and the test runs only when some unrelated requirement happens to be touched. Tests now declare conformance.home.k3s/scope: whole-repo and run.sh unions them in via --include-scope; the three stages are deleted. 10 of 13 tests are whole-repo, 3 stay path-scoped with the path map widened instead (infra/* -> R-ENV-01, ci/* -> R-TEST-06). A new meta-test makes the bespoke pattern fail the gate if it creeps back, and a change under conformance/tests/<test>/ now attributes that test's own requirements, so weakening a test is gated by what it certifies. rc-3 (SKIPPED is UNWIRED, not green) is preserved and demonstrated; the incident narratives moved into the tests they describe rather than being deleted. Gate cost for a scoped change rises 20.7s -> 41.8s, a ceiling any empty-touched-set change already paid. |

fix(monitoring): alert when a Velero schedule has NEVER backed up, or is paused
VeleroNoRecentBackup could not fire for the failure mode that actually happened.
`(time() - velero_backup_last_successful_timestamp{schedule!=""}) > 24*3600` is the
right SHAPE — per-schedule, un-aggregated — but Velero only creates that series once
a backup for the schedule SUCCEEDS, and `time() - <absent series>` yields no series.
So it detects "backed up once, then stopped" and is structurally INERT on "never
backed up". Prod ran with `velero-daily` (the schedule carrying VOLUME DATA) paused
and never-successful: no volume backups at all, nothing alerted, and it was masked
because `velero-daily-resources-only` completed cleanly every 03:00, so every other
backup signal read green while only Kubernetes objects were protected.
A PromQL-only fix is impossible, verified rather than assumed: velero v1.18.1 exports
35 velero_* metric names and every one carrying a `schedule` label is created by a
backup ATTEMPT, not by the Schedule object. A throwaway `paused: true` Schedule on
prod produced ZERO velero_* series, and nothing exposes `spec.paused`. The fact is
not in the TSDB, so the Schedule CRs are exported via kube-state-metrics'
custom-resource-state collector — the path this repo already uses for
kube_node_labels — as kube_velero_schedule_{created,paused,protects_volume_data,info}.
Proven by running KSM v2.20.0 with this exact config against prod's API: the CRD
list/watch rule the chart adds is MANDATORY, not cosmetic — without it KSM emits the
CRS metrics as an empty set, silently.
Three rules, all keyed on PROPERTIES rather than schedule names:
* VeleroScheduleNeverBackedUp (critical) — a Schedule older than 36h with no
successful backup ever. The 36h grace comes from creationTimestamp so a newly
added schedule is not paged before its first run is even due.
* VeleroSchedulePaused (warning) — the direct root-cause signal; a paused backup
schedule must never be silently indefinite.
* VeleroNoVolumeDataBackup (critical) — THE ANTI-MASKING RULE. Fires unless some
schedule with spec.template.defaultVolumesToFsBackup=true succeeded in 36h, so a
healthy resources-only schedule can never make the platform look protected.
Reading the property that DEFINES volume protection (not a name list) matches
platform/velero/volume-policies.yaml and survives renames. `or vector(0)` is
load-bearing: `count(<empty>) == 0` returns no series and would be inert —
absence of the exporter is deliberately the alarm.
Adds the repo's first Prometheus rule-unit-test harness (platform/monitoring/tests/,
wired as the `prom-rules` gate stage). It flattens the COMMITTED PrometheusRule CRs —
never a copy — and pins every rule in the group both ways: quiet on today's healthy
prod state, firing on the reconstructed bad state, with `for:` durations asserted.
Two mutation checks confirm the tests are not vacuous: dropping `or vector(0)` and
breaking the `unless on (schedule)` join each turn the suite red. This is the tool
that makes both of this repo's recurring alert bugs — permanently-firing and
structurally inert — provable offline, which neither yamllint, Kyverno, nor a healthy
cluster can do.
Proof of the fix is by construction; the live metrics cannot show it any more, because
`velero-daily` was unpaused on 2026-09-12 and has since completed 2492/2492 items.
The throwaway probe Schedule and the probe KSM deployment were deleted and the
deletion confirmed; `velero-daily` remains unpaused.

fix(ci): declare whole-repo scope instead of hand-writing a gate stage per invariant
R-TEST-03 runs the conformance subset a change TOUCHES. That has one blind spot, and it
is the worst-shaped kind: an invariant that quantifies over the whole tracked tree — or
over subtrees ci/touched-requirements.sh's coarse path map keys to NOTHING (apps/, infra/,
most of platform/) — cannot be selected BY the requirements a change touches, because the
change most likely to break it attributes no requirement at all. Requirement-scoped
selection then filters the check out of exactly that change.
The repo's answer had been a hand-written "UNCONDITIONAL" stage per such check in
ci/l0.sh: 3c flux-postbuild-substitution, 3d keycloak-client-secret-reconciler, 3e
bulk-tier-distinct-from-replicated. Three near-identical 12-line rationales, three
hardcoded check.sh paths, three copies of the same rc 0/3/* case block — and worst, a
mechanism that failed SILENTLY, because whoever added the NEXT whole-repo invariant had
to REMEMBER to write a stage, and if they forgot the check ran only when some unrelated
requirement happened to be touched.
A test now DECLARES the scope of its invariant and the runner enforces it:
metadata:
annotations:
conformance.home.k3s/scope: "whole-repo"
* conformance/lib/common.sh conf_dirs_for_scope(s) resolves the annotation. Carries the
general rationale, once, instead of per stage.
* conformance/run.sh --include-scope SCOPE unions declaring tests into select_dirs,
still bounded by --layer. New --print-selection resolves the
selection and exits, running nothing.
* lib/run_l1_offline.py --unwired-scope: a SKIP of a declaring test exits 3, not 0.
--summary-out: one step-summary line per executed check.
* ci/l0.sh Stage 3b gains --include-scope whole-repo and an rc-3 arm.
Stages 3c/3d/3e DELETED (-150 lines).
* ci/l1.sh, ci/conformance.sh pass --include-scope too, so the next whole-repo invariant
at ANY layer needs only the annotation.
rc 3 SEMANTICS PRESERVED EXACTLY. A whole-repo check reporting "nothing to audit" is
reporting that the tree it audits has VANISHED. The deleted stages called that "not a
pass" and set the gate's rc=3; the runner now returns 3 and ci/l0.sh maps it to rc=3.
A missing check file still degrades to not-green, never to silence.
THE REASONING WAS RELOCATED, NOT DELETED. Each stage's incident narrative moved into the
header of the test it describes, beside its scope annotation: the Cilium k8sServiceHost
empty-substitution CNI outage (2026-09-01), 12 unusable Keycloak clients behind a green
cluster (2026-09-06), and a multi-TB bulk volume landing on the 3-replica tier.
AUDITED ALL 13 EXISTING l0-static TESTS, individually. 10 declare whole-repo scope; 3 are
DELIBERATELY left requirement-scoped and say so in their own headers:
* placeholder-guard-coupling — inputs are bootstrap/ + clusters/, both already mapped to
a requirement it declares. Scoping cannot hide a breaking change.
* dev-nodes-provisioned-as-code — inputs are infra/ and nothing else.
* spec-immutability-enforced — inputs are ci/ and the read-only spec repo.
The latter two were nonetheless under-gated because the PATH MAP was incomplete, which is
the right place to fix a path-scoped invariant: infra/* -> R-ENV-01 added, and R-TEST-06
added to .gitea/*|ci/* (it is no longer an uncovered ID — spec-immutability-enforced
carries the label, so attributing it no longer false-blocks the coverage gate).
NEW conformance/tests/l0-static/whole-repo-invariants-wired (R-TEST-03) keeps the
declarative mechanism honest for ALL declaring tests at once, replacing the three tests'
individual "ci/l0.sh greps my own check.sh path" self-assertions. It proves the union
EMPIRICALLY: with a requirement filter matching no test the L0 selection is empty, and
with --include-scope it is every declaring test; a scope-declared synthetic SKIP exits 3
while an undeclared one exits 0; and a ci/*.sh that hardcodes a check.sh path must belong
to a test that also declares the scope, so the bespoke pattern cannot creep back.
TASK 2 — a changed test attributes the requirements it CERTIFIES.
ci/touched-requirements.sh gains detection rule 3: a change anywhere under
conformance/tests/<test>/ attributes that test's own conformance.home.k3s/R-* labels, read
from its chainsaw-test.yaml. The content scan could not close this — it reads only
added/removed lines, so it sees a change to the LABEL BLOCK but not to the test BODY,
which is exactly the case that matters. Labels are read from HEAD or, failing that, from
the BASE, so DELETING a test still attributes what it used to certify; otherwise removing
the only verifier of a requirement is the cheapest way to make the gate stop checking it.
Whole-line `#` comments are dropped first and *.md is untouched, honouring the existing
"reference, not declaration" rules.
Both changes are fail-closed: every one of them can only ADD tests or requirements to a
run, never remove one.
TESTS: new ci/tests/touched-requirements-test-attribution.test.sh (15 assertions) covers
rule 3 — body-only edit, nested-fixture walk-up, test deletion, header-comment R-IDs not
attributed, non-test paths unaffected, and both new path-map entries. The two existing
suites still pass (39 assertions). `make -C ci test` runs all three.

merge: qBittorrent can finally write where the arrs can see it
qBittorrent's SavePath was /downloads and no such directory existed in the container, so the download client had no working destination and nothing downstream could see its output. It now mounts the same NFS export the arrs use, narrowed to the downloads subtree via subPath — one mount, so the EXDEV hardlink trap the bulk-tier test guards stays closed. PUID/PGID are load-bearing: the export is owned 1000:1000 and the image's default 911 is denied. |

merge: CNPG primaries spread one per node, and the condition is now reported
All three primaries had re-concentrated onto prod-1 (the node with known etcd/Longhorn I/O contention), so losing it meant three simultaneous failovers. Two switchovers rebalanced them; semaphore-db deliberately stays on prod-1 as the lightest writer, saving a third write interruption. CNPG offers no role-aware scheduling — targetPrimary exists only under status — so the placement is CURRENT, NOT DURABLE: the next failover or rolling update can re-concentrate it. What is durable is CNPGPrimariesCoLocated, which reports the condition instead of leaving it to be found by hand. |

fix(devcontainer): dev.sh defaults to prod — dev is decommissioned
Every unprefixed './dev.sh run kubectl ...' pointed at the dev cluster, which was decommissioned on 2026-09-12. The banner cheerfully named dev and the command then hung or errored against a context that no longer answers, with nothing saying the cluster is gone. I hit this repeatedly tonight. CLUSTER=dev is still accepted rather than removed, because the dev VM disks were deliberately kept so the environment is reversible — but it now warns.

feat(qbittorrent): attach the downloads area of the bulk export — the chain was broken end to end
qBittorrent was the one member of the download chain with NO media volume.
Its live config said
Session\DefaultSavePath=/downloads/
Session\TempPath=/downloads/incomplete/
Downloads\SavePath=/downloads/
while `ls /downloads` in the container returned "No such file or directory".
The catalog entry declared exactly one volume — config at /config on longhorn —
and carried a comment deferring the downloads volume "until OQ-2 is resolved".
OQ-2 WAS resolved (schema 1.5.0 static bulk NFS PVs); plex, sonarr, radarr and
nextcloud all took their mounts and qBittorrent's was simply never added. So the
download client was writing, or failing to write, a path that did not exist —
and anything it did create would have been invisible to sonarr/radarr, lost on
every pod recreation, and consuming the node's ephemeral disk until then.
WHAT THIS ADDS to catalog/qbittorrent.yaml (rendered into apps/wave-0):
* storage[downloads]: class bulk, export /mnt/Storage/plex, subPath downloads,
mountPath /downloads, 9Ti advisory. ONE mount of the SAME export sonarr,
radarr (rw) and plex (ro) already consume, narrowed to the handoff subtree.
* env PUID=1000 / PGID=3000. LOAD-BEARING, not cosmetic: the container ran as
uid 911 and /mnt/Storage/plex/downloads is 0755 owned 1000:1000, so the
export would have mounted cleanly and then failed every write with EACCES.
Measured both ways on prod: a write as uid 1000 succeeded, the same write as
uid 911 was denied.
* podSecurityContext.fsGroup 3000, for the LONGHORN config PVC only, exactly as
sonarr/radarr set it — fsGroup is a no-op on an in-tree NFS volume.
WHY subPath AND NOT THE EXPORT ROOT AT /media (sonarr/radarr's shape): a download
client has no business writing the library. The arrs need the root mount because
THEY hardlink downloads/ -> tv/|movies/ and link() is a same-MOUNT operation;
qBittorrent performs no such link, so narrowing to downloads/ removes movies/,
tv/ and photos/ from its mount namespace without removing any operation it
performs. It is still ONE mount of the export, so the L0 assertion that no
workload mounts one export twice (the EXDEV trap) holds — and the arrs' own
link() stays intra-mount. Proven live: nlink 1 -> 2, same inode, no EXDEV, every
step executed as uid 1000.
NETWORK: nothing to grant and nothing to steer. An NFS PersistentVolume is
mounted by the NODE KERNEL in the host netns — the established socket to
192.168.2.102:2049 is on the node's own LAN address, the pod netns has no socket
to 2049 at all, and no CiliumNetworkPolicy on this cluster names that host or
port. `ip route get 192.168.2.102` picks eno1 even on the tunnel-owning node, and
Cilium's own egress map lists 192.168.0.0/16 as an Excluded CIDR for every
vpn-class pod while 0.0.0.0/0 goes to the gateway. Public egress still exits the
PIA address; the VPN guarantee is untouched.
NOT CLOSED BY THIS COMMIT, deliberately: absolute paths still differ between this
pod (/downloads/x) and the arrs (/media/downloads/x), so Completed Download
Handling needs one Remote Path Mapping per arr. That lives in the arrs' own
databases, not in git.

feat(cnpg): alert when >1 CNPG primary shares a node — the drift CNPG cannot prevent
`instances: 3` + `podAntiAffinityType: required` fixed the INSTANCE spread but moved
the PRIMARY concentration from k3s-prod-2 to k3s-prod-1: all three primaries
(keycloak-db-2, nextcloud-db-2, semaphore-db-2) ended up on one node, so losing it
meant three simultaneous failovers.
There is NO declarative fix, established from the CRD installed on prod (CNPG 1.30.0,
clusters.postgresql.cnpg.io/v1) rather than from memory. Every spec.affinity field and
spec.topologySpreadConstraints applies to "all the cluster's pods" and is not role-aware;
spec.replica.primary names a Cluster object in a distributed topology, not a node;
primaryUpdateMethod/switchoverDelay/primaryLease govern how a promotion happens, never
where. `targetPrimary` exists only under STATUS, never spec — so `cnpg promote` is an
imperative status patch by construction and there is nothing to put in git. The obvious
workaround is worse than nothing: pod anti-affinity is only ever
...IgnoredDuringExecution while CNPG promotes by relabelling a RUNNING pod, and with
3 instances on 3 nodes it would leave the third instance unschedulable.
So this commits the part that IS durable — visibility — and rebalances live.
CNPGPrimariesCoLocated joins CNPG's own answer to "who is primary" (the <cluster>-rw
Service selects only the primary) against the node: kube_endpointslice_endpoints carries
endpoint_nodename + targetref_name, which two label_replaces lift into node/pod. Neither
family works alone — cnpg_* metrics have no node label, and kube_pod_labels is EMPTY here
(no kube-state-metrics label allowlist), so cnpg.io/instanceRole is not in Prometheus at
all. `* on (namespace, pod) group_left () cnpg_collector_up` keeps an unrelated `*-rw`
Service from triggering it, and uses the one metric present for EVERY instance rather than
the cnpg_pg_stat_* family that is missing for nextcloud-db.
A Ready-node gate stops this becoming another permanently-firing alert: with three
clusters on three nodes a node loss NECESSARILY co-locates two primaries, so the rule
only speaks when the spread is actually achievable, and re-arms when the node returns.
Proven both ways. Live: the expr returned {node="k3s-prod-1"} => 3 before, empty after,
with the inner join still resolving all three primaries (quiet because false, not blind);
loaded into prod's Prometheus as a throwaway `for: 1m` twin it went pending at +70s and
firing at +130s. alerts.promtool-test.yaml pins four cases under promtool 3.14.0 (the
exact version prod runs) and is mutation-checked — dropping the join, dropping the gate
or shortening `for:` each makes a test FAIL.
Rebalanced live, one cluster at a time: keycloak-db -> k3s-prod-2, nextcloud-db ->
k3s-prod-3, semaphore-db deliberately LEFT on k3s-prod-1 (lightest writer, and that node
has the known etcd/Longhorn I/O contention) — two switchovers, not three. Write outage
measured with a `select txid_current()` probe, not estimated: 9.4s and 9.43s, one
contiguous burst each. All three back to readyInstances: 3 with
synchronous_standby_names = ANY 1 (...) and both standbys streaming/quorum.
The placement is CURRENT, NOT DURABLE, and the alert is the point: the next failover or
rolling update can re-concentrate the primaries, and now that gets reported instead of
discovered by hand.

merge: the nextcloud database has never been monitored
cnpg_metrics_exporter lacked CONNECT on the nextcloud database: an out-of-band REVOKE materialized its datacl and dropped PUBLIC's implicit CONNECT, which keycloak and semaphore still inherit. CNPG's API cannot express a database-level grant, so this follows the repo's existing level-triggered CronJob reconciler pattern rather than a one-shot Job that a rebuild would silently skip. CONNECT only; pg_monitor already carries the read access. |

fix(cnpg): grant cnpg_metrics_exporter CONNECT on the nextcloud database
The CNPG metrics exporter could not CONNECT to the `nextcloud` application
database, so every user-defined collector query against that target failed on
all three instances:
FATAL: permission denied for database "nextcloud" (SQLSTATE 42501)
DETAIL: User does not have CONNECT privilege.
The whole cnpg_pg_stat_* / pg_settings / pg_postmaster family was therefore
MISSING for nextcloud-db while the scrape target still reported up=1 — the blind
spot platform/cnpg/alerts.yaml's CNPGMetricsCollectorErroring was written to
catch. It had been firing on all three pods; measured before this change,
cnpg_pg_settings_setting had 765 series for keycloak, 765 for semaphore-db and
ZERO for nextcloud-db. Nextcloud's database had never been monitored.
Root cause is the live ACL, not the spec — all three Cluster specs bootstrap
identically:
nextcloud : datacl = {nextcloud=CTc/nextcloud} <- explicit, no PUBLIC entry
keycloak : datacl = NULL
semaphore : datacl = NULL
A NULL datacl means PostgreSQL's defaults, which include CONNECT for PUBLIC, so
keycloak and semaphore admit the exporter only by inheriting PUBLIC's implicit
CONNECT. On `nextcloud` something ran the equivalent of REVOKE ALL ON DATABASE
nextcloud FROM PUBLIC, which materialises datacl and drops that implicit entry.
That REVOKE is in neither this repo nor DECISIONS-LOG.md — it was applied out of
band, which is why the remedy has to be declarative rather than another hand-run
psql.
CNPG 1.30.0 cannot express a database-level GRANT (verified against the live
CRDs): `Database` has no ACL field (`allowConnections` is the datallowconn flag,
not a per-role grant), and managed.roles/DatabaseRole cover role attributes plus
`inRoles` membership only — and membership would hand the exporter the owner's
CREATE/TEMP and all table access to buy one CONNECT. postInitApplicationSQL runs
once at bootstrap, so it cannot repair the already-bootstrapped instances that
are actually broken. So this follows the pattern the repo already uses for state
Flux cannot reach: the level-triggered CronJob reconciler alongside
platform/keycloak/client-secret-reconciler.yaml. A one-shot Job is deliberately
avoided — a completed Job never re-runs, so a rebuild or PITR restore would
silently reopen the blind spot.
Exactly one privilege, and nothing else:
GRANT CONNECT ON DATABASE nextcloud TO cnpg_metrics_exporter;
giving `cnpg_metrics_exporter=c/nextcloud` — CONNECT only, no CREATE, no
TEMPORARY, no ownership, no superuser, no table or schema grants. Nothing more is
needed because CNPG already creates the role as a member of the built-in
pg_monitor role (verified on all three clusters), which carries the read access
the collector's pg_catalog queries want. It runs as the database OWNER, not a
superuser: enableSuperuserAccess stays off, and a database owner holds the grant
option on its own database.
Verified live on prod:
* the grant issued under SET ROLE nextcloud, proving no superuser is needed;
* permission-denied and "Error collecting user query" both went to 0 on
nextcloud-db-1/-2/-3, i.e. every collector query now succeeds;
* cnpg_pg_settings_setting now 765 series for nextcloud-db, matching the other
two, and cnpg_pg_postmaster_start_time present on all three instances;
* cnpg_last_error = 0 on all NINE instances, so keycloak-db and semaphore-db
are unaffected and their datacl is still NULL;
* convergence proven by revoking the grant again and letting the committed
CronJob restore it, then re-running it against a converged database to show
idempotence;
* CNPGMetricsCollectorErroring, firing on all three pods beforehand, has
cleared (`for: 6h` delays firing, not resolution).

fix(cnpg): scope DR alerts to the CLUSTER, not the pod — stop a permanent false positive
CNPGNoRecoverabilityPoint has been firing continuously on prod against six
pods — keycloak-db-1/-3, nextcloud-db-1/-3, semaphore-db-1/-3 — i.e. exactly
the REPLICAS of all three Clusters, while the databases themselves are fine:
every Cluster reports firstRecoverabilityPoint=2026-09-07T07:0x, a
lastSuccessfulBackup within the last few hours, ContinuousArchiving=True and
LastBackupSucceeded=True.
Root cause is aggregation scope, not archiving. `cnpg_collector_first_recoverability_point`
reads the backup CATALOGUE, which only the primary owns; a replica reports a
hard 0 for as long as it is a replica. The metric carries no cnpg.io/cluster
label (its label set on prod is container/endpoint/instance/job/namespace/pod),
so `max by (namespace, pod)` evaluated each replica as its own subject and an
`== 0` comparison then held forever. The rule went from correct to permanently
wrong the moment the Clusters went to `instances: 3`; nothing about the
expression changed.
WHY THIS IS WORSE THAN HAVING NO ALERT. An alert that is always firing has
zero information content: its value is identical in the healthy state and in
the failure state, so it cannot distinguish them. It is worse than silence in
two specific ways. First, it trains the operator to delete the notification on
sight, so the day a base backup genuinely stops the seventh identical email is
discarded with the other six — the alert actively MASKS the failure it was
written to catch, which for a DR alarm means discovering the loss at restore
time. Second, it is indistinguishable from a broken alert, so nobody can tell
whether the absence of new alerts means health or means the rule rotted. This
file exists because a real 38-hour archiving failure told nobody; a rule that
cries wolf about six healthy replicas rebuilds exactly the blindness it was
supposed to remove. This repo has been here before — see the permanently-firing
critical VPNTunnelDown post-mortem in platform/monitoring/alerts.yaml.
Fix: group by (namespace, job) and aggregate `pod` away. The CNPG operator
creates one PodMonitor per Cluster, named after the Cluster, in the Cluster's
namespace, so prometheus-operator derives job="<namespace>/<cluster>" —
keycloak/keycloak-db, nextcloud-db/nextcloud-db, semaphore-db/semaphore-db —
which identifies the CNPG Cluster uniquely. `job` rather than bare `namespace`
deliberately: namespace alone works today (one Cluster per namespace, verified
live) but would let two Clusters in one namespace mask each other, since the
healthy one's non-zero value would satisfy `max` for both. The alert now
states what its summary always claimed — this CLUSTER has no recoverability
point — and fires only when no instance of that Cluster reports one.
Proven live against prod Prometheus, read-only (promtool query instant):
OLD max by (namespace, pod) (...) == 0 -> 6 series, and 6 ALERTS firing
NEW max by (namespace, job) (...) == 0 -> empty
The new expression is not vacuous: forcing the metric to 0 for one cluster's
primary only yields exactly one series, {job="keycloak/keycloak-db"}, so a
genuine single-cluster loss of DR still alerts, per cluster. `promtool check
rules` passes on all 5 rules.
CNPGNoRecentBaseBackup carried the same defect and is fixed the same way.
`cnpg_collector_last_available_backup_timestamp` is also primary-only: on prod
the primaries read 3.1h/2.1h/0.1h old while all six replicas read 0, i.e.
time()-0 = ~56.7 YEARS. It was not firing only because the `> 0` guard was
load-bearing — a single clause was all that stood between this rule and six
more permanent false positives, too thin a margin for a DR alarm. Aggregating
`pod` away removes the dependence: `max` takes the primary's timestamp as the
cluster's answer, and the guard now means "this cluster has had at least one
backup". Verdict unchanged live (old empty, new empty).
The other three rules were audited and deliberately left on `by (namespace, pod)`:
* CNPGWALArchiveBacklog — every instance reports archive_status and the shape
is `> 0`, so a replica at 0 never fires and no pod can mask another; `pod`
names the instance whose archiver is stuck.
* CNPGWALVolumeNotRecycling — per-pod is REQUIRED, not merely safe:
aggregating it away would compare one instance's WAL count against
another's max_wal_size.
* CNPGMetricsCollectorErroring — unchanged in meaning AND grouping. Its
grouping is already correct: cnpg_last_error is genuinely per-instance, and
prod proves it discriminates rather than tracking role — all three
nextcloud-db pods report 1 while all six keycloak/semaphore pods report 0.
It is a true positive (the nextcloud 42501 CONNECT grant) owned by separate
work; nothing here silences or rescopes it.
The general rule, recorded in the file: `== 0`/staleness shapes must aggregate
`pod` away or every structurally-silent pod fires forever; `> 0` shapes are
safe per-pod and keep the instance name.

feat(gitea): render gitea-allow-flux-ingress — prod's GitOps source, in git at last
The CNP that lets flux-system's source-controller clone from the in-cluster Gitea Service was APPLIED LIVE on prod on 2026-09-13 and existed nowhere in this repo. It carried a provenance annotation saying so. Until now it could not be authored: the gitea CNPs are GENERATED from the catalog entry, and the contract had no field for "also admit this in-cluster client" (fixed in the previous commit). Why it matters more than a missing allow normally would. prod's GitRepository points at the Service, not a public name (clusters/prod/kustomization.yaml: `url: http://gitea.gitea.svc.cluster.local:3000/Home-Network/home-network-k3s-impl.git`), deliberately, so prod's GitOps depends on neither public DNS, Cloudflare, prod's own Gateway nor ${BASE_DOMAIN}. But gitea-allow-gateway-ingress admits only `fromEntities: [ingress]`, so source-controller's clone was dropped — and the HTTPRoute that would have served the post-apex-flip public name instead lives in a DOWNSTREAM tier that cannot apply while the source is down. Source down -> routes never rename -> source stays down. Every `kubectl delete cnp` and every cluster rebuild re-armed that deadlock, and it would have been extremely hard to diagnose cold. The rendered object is EQUIVALENT to the live one — same apiVersion/kind, same name/namespace/labels, and a byte-identical spec (endpointSelector app.kubernetes.io/name=gitea; fromEndpoints matchLabels k8s:io.kubernetes.pod.namespace=flux-system; toPorts 3000/TCP), verified against `kubectl --context k3s-prod -n gitea get cnp gitea-allow-flux-ingress -o json`. The name matches, so Flux ADOPTS the live object in place: no spec change, so no policy recompute and no flap on prod's own source. The only difference is that the rendered object carries no `homelab.keithjackson.dev/provenance` annotation — the reasoning now lives where the object is authored, in catalog/gitea.yaml, next to the field that generates it. Golden re-rendered with the canonical command; the whole apps/ diff is the one new document. Co-Authored-By: Claude Opus 5 <[email protected]> |

feat(renderer): inClusterClients — authorable direct east-west ingress (schema 1.5.0)
A platform controller that dials a service's ClusterIP directly had NO authorable
form in the ServiceDefinition contract:
* ingressRoutes renders the north-south allow only — gateway-ingress admits
`fromEntities: [ingress]`, the Gateway's Envoy identity, and nothing else;
* dependencies compiles edges only BETWEEN CATALOG SERVICES, from the source
entry's own declaration.
Under the default-deny baseline (R-NET-01) such a client is therefore DROPPED, and
the only way to unblock it was a live `kubectl apply` of a hand-written CNP — a
cluster object outside git, one `kubectl delete` or one rebuild from coming back.
`inClusterClients: [{namespace, port, protocol?, name?}]` closes that. Each entry
renders ONE least-privilege ingress CiliumNetworkPolicy: this service's
endpointSelector, `fromEndpoints` matching ONLY `k8s:io.kubernetes.pod.namespace`,
`toPorts` carrying ONLY the declared port/protocol — never `fromEntities: all`.
Additive: the namespace default-deny keeps denying everything undeclared (R-NET-02),
and the entry is NOT a dependency edge, so it creates no wave ordering.
Shape notes:
* selected by NAMESPACE, not pod labels: an upstream controller's labels belong to
its chart, not to this platform's contract. The cost is explicit — every pod in
that namespace is admitted on that port, so the field is for platform-controller
namespaces (flux-system, monitoring), never a shared one. The schema description
says so.
* optional `name` (default: the namespace) only names the rendered policy,
`<service>-allow-<name>-ingress`. That name is operator-facing (kubectl get cnp,
a Hubble drop), and pinning it lets an allowance that already had to be applied
live be authored under its EXISTING name, so Flux adopts the live object in place
instead of creating a near-duplicate and leaving the original unmanaged.
* one field, not a policy DSL: no arbitrary selectors, entities or CIDRs.
Covered by render.py --selftest (4c): name/namespace/selector/port shape, no
fromEntities widening, default-deny still `ingress: []`, the gateway allow not
displaced, `name` defaulting to the namespace, and nothing rendered when the field is
absent. No golden changes here — no catalog entry uses the field yet.

fix(gitops): prod's source is the in-cluster Service, not a public name
The apex flip deadlocked prod's GitOps and this is the durable fix. The GitRepository pointed at a public hostname. The flip renamed prod's HTTPRoute hostnames, so that name stopped serving — but the HTTPRoute that would serve the new name lives in a DOWNSTREAM tier which cannot reconcile while the source is broken. Source down -> routes never rename -> source stays down. Observed live: srcReady=False, "unable to list remote for https://gitea.home.keithjackson.dev". Pointing at gitea.gitea.svc.cluster.local:3000 removes the cycle permanently: prod's GitOps no longer depends on public DNS, Cloudflare, its own Gateway, or ${BASE_DOMAIN}. No future domain change can sever prod from its own source. Plain http is deliberate: cluster-internal traffic to a ClusterIP, TLS terminates at the Gateway for external clients, the GitRepository has no secretRef (anonymous clone), and all secrets are SOPS-encrypted at rest regardless of transport.

fix(gitops): move prod's own Git source with the apex flip
The GitRepository url is a hardcoded literal, not templated on ${BASE_DOMAIN}, so
the apex flip did not carry it. But the flip renames prod's HTTPRoute hostnames, so
external-dns (policy=sync) deletes gitea.prod.home.keithjackson.dev and CoreDNS's
split-horizon zone moves from prod.home. to home. — which would have severed prod
from its OWN GitOps source moments after the flip reconciled.
Landed in the same push as the flip deliberately: prod has not yet fetched

feat(dns): prod takes the apex — home.keithjackson.dev
Dev is decommissioned and has released the name. Prerequisites completed and
verified BEFORE this flip:
1. dev's 18 A records released by its own external-dns (policy=sync; sources
deleted after suspending dev's Flux so they could not be recreated).
2. dev's 18 LEGACY UNPREFIXED TXT registry entries deleted from Cloudflare by
hand. external-dns v0.21.0 deleted only the `a-` prefixed form and then logged
"All records are already up to date" — it would NEVER have cleared the older
unprefixed format it no longer writes but still READS for compatibility. They
carried `owner=default`; prod runs `owner=prod`, so prod could not have
claimed these names while they existed. This was the real blocker, and it was
invisible until measured.
3. dev's `*.home.keithjackson.dev` + apex Certificate deleted so it stops
renewing. Issued ~18d ago, so prod's request is #1 this week against LE's
duplicate limit (5 per identical name set per week).
Verified at the AUTHORITY (betty.ns.cloudflare.com), not via a resolver: 1.1.1.1
served stale TXT for minutes after deletion and would have shown a false failure.
UNCHANGED, deliberately: EXTERNALDNS_TXT_OWNER_ID stays `prod` — giving prod
`default` would let it adopt and sync-delete records it does not own, which is the
2026-09-04 incident. EXTERNALDNS_DOMAIN_FILTER stays the ZONE `keithjackson.dev`:
finding F-DNS1 proved a strict subdomain filter drops the hosted zone and external-dns
then publishes NOTHING.
The zone has wildcards `*.keithjackson.dev` and `*.home.keithjackson.dev` pointing at
the public IP (legacy non-k3s prod). Dev's specific records were shadowing the latter;
prod's new specific records shadow it again. The legacy stack lives on
`*.keithjackson.dev` and is untouched.
k3s_base_domain moves with it to hold the [parity] contract, but that value renders
the apiserver's install-time oidc-issuer-url: it does NOT take effect until the
k3s_server role re-renders config.yaml and k3s is restarted serial: 1. Until then the
apiserver trusts the OLD issuer while Keycloak serves the NEW one, so kubectl OIDC
fails in that window. Cert-based kubeconfigs are unaffected.

test(conformance): gate the URL desired state, and prove the selftest can fail
L0 (212 assertions, was 175):
* runs ci/render-keycloak-client-urls.py --check, so client-urls.yaml must be exactly
what the realm import renders. A hand edit that makes the two disagree is
unmergeable -- this is what keeps the realm import the single source of truth for
hostnames rather than just the place they were first typed.
* asserts client-urls.yaml and the realm import are rendered by the SAME Flux
Kustomization. postBuild.substituteFrom is per-Kustomization, so a split would let
one ${BASE_DOMAIN} resolve to two different values and the realm would converge on
a hostname the HTTPRoutes do not serve.
* asserts the desired state uses no substitution token the realm definition lacks,
names only clients the import declares, and declares no field outside the
five-field write surface; that the CronJob mounts it readOnly at the path the
script defaults to; and that the script, renderer and check agree on which fields
are writable.
* NEW mutations.py: injects 12 plausible regressions into the EXTRACTED script and
requires --selftest to catch every one. A passing suite proves nothing if it cannot
fail, and "reported success while the realm was broken" is precisely what this
component exists to end -- so the same standard applies to its own test. ~20s.
L2: the audit Job now mounts keycloak-client-urls and asserts
KEYCLOAK_CLIENT_URLS_AUDIT_OK. Without that it would pass on a realm still holding
pre-migration redirect URIs -- the exact state prod was measured in.
Alerts: the existing Failing/Stale pair is EXTENDED to name redirect-URI drift, not
duplicated. One CronJob gets one pair; a second pair on the same job_name regex would
fire twice for one cause. No new critical, no new permanently-firing rule.

feat(keycloak): reconcile client redirect URIs, not just client secrets
The realm import is a one-shot that never re-runs, so a redirect URI changed in git reaches the realm never. Prod's stored URIs were measured still on the pre-migration hostname while git declared the new one -- after a BASE_DOMAIN flip every OIDC login fails with a redirect_uri mismatch, with the CR still reading Done=True and nothing alerting. Same failure class as the literal-placeholder secrets, same cure. EXTENDS the existing reconciler rather than adding a sibling. Decisive reason: a URL write needs NO new endpoint. It is the same minimal client PUT, and the current URLs already come back in the allow-listed client lookup -- so the allow-list is widened by nothing and the users/groups/roles/authentication guarantee is preserved unchanged rather than re-declared in a second copy. The ConfigMap also carries exactly one script key by L0 contract, so a sibling would have had to fork ~300 lines of safety-critical code that the header explicitly forbids forking. Reconciles redirectUris, webOrigins, rootUrl, baseUrl, adminUrl -- only the fields a client actually declares, and on a write only the fields that actually drifted. A field the desired state omits is UNMANAGED and left untouched; absence never means force-to-empty. THE TWO PASSES ARE INDEPENDENT. Each reads its own desired state and fails closed for its own fields only. A malformed URL ConfigMap cannot stop client-SECRET repair, which would otherwise make credential healing depend on a hostname file. List fields compare order-insensitively (sorted, not set -- duplicates are still drift), because Keycloak does not preserve the authored order of redirectUris and an order-sensitive compare would rewrite every client forever while reporting success. --selftest grows to 84 assertions covering the domain flip, a client gaining a URI, a client losing a stale one, a public client's URLs being managed while its secret is not, per-pass fail-closed, order-insensitivity, and a server that accepts a PUT without applying it.

feat(keycloak): render the client-URL desired state from the realm import
The realm import is a one-shot: once Done=True it never re-runs, so a redirect URI
changed in git never reaches the realm. Healing that needs a DESIRED STATE the
reconciler can read -- and the reconciler pod has no Kubernetes API access at all
(automountServiceAccountToken: false), so it cannot read the KeycloakRealmImport CR.
Its desired state must be mounted, hence a ConfigMap.
A hand-authored ConfigMap would be a second source of truth for every public
hostname in the realm, free to disagree with the import -- the same shape as the bug
being closed. So it is GENERATED from the import and the render is gated, the same
render==golden idiom catalog/render.py already uses for apps/.
URL strings are copied VERBATIM: a ${BASE_DOMAIN} token in the source appears
unchanged here, and both files are rendered by the SAME Flux Kustomization
(./platform-config), so both are substituted in one pass with one value. The
renderer never parses a hostname and never reads cluster-vars, so there is no
second place the domain can be decided.

fix(conformance): the dirty-tree assertion must judge HONOURED evidence
One historical `-dirty` row reddened this gate permanently, even after a clean re-run of the same test. status.py already resolves duplicates latest-wins (latest_by_test), so a superseded row is not evidence of anything — but this check iterated every row, so the poisoned row from the git_sha bug (fixed in the parent commit) would have failed the audit forever. The dirty-tree assertion is now scoped to rows status.py would actually honour, by importing latest_by_test rather than reimplementing the rule, so the two cannot disagree about which rows are live claims. Structural assertions — provenance keys, sentinel, test-still-exists — still apply to EVERY row. Nothing is erased: the row stays in the ledger and runs/20260913T014437Z-19fc8bc/ run.log stays committed. It simply stops being read as a live claim. Verified the guard is intact afterwards — the check still REFUSES both forgeries it is built to catch (a self-skip presented as a pass, and a proven row from the root commit). A dirty-then-clean sequence is also the normal shape of noticing a dirty tree, fixing it, and re-running; that should not permanently fail an audit. Co-Authored-By: Claude Opus 5 <[email protected]> |
