From 574088dfebf4d51f167cf8a97bce4b65a724faea Mon Sep 17 00:00:00 2001 From: Keith Jackson Date: Mon, 31 Aug 2026 22:17:51 -0500 Subject: [PATCH 01/16] docs(prod): open Phase 7 (prep only) + T-7.1 bare-metal provisioning checklist MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The operator added the first production node (k3s-prod-1, 192.168.2.10 — HP EliteDesk 800 G5 Mini, i7-9700T/31GiB, Debian 13, VT-x + /dev/kvm) and opened roadmap Phase 7 for PREP WORK ONLY: no k3s install until the R-ENV-02 blockers close and the gate is green. Records the Phase-7 entry-gate position honestly: the operator has declared hardware ready, but "Phases 1-6 proven in dev/test" is NOT met (37/51 conformance; R-ENV-01/02/03 themselves uncovered). Proceeding is an explicit, accepted risk — not an oversight. Adds infra/PROD-PROVISIONING.md (T-7.1, design-only): firmware/BIOS, disk layout, OS, network, access, Ansible reuse, repo blockers, build sequence, Phase-7 exit criteria. Key findings recorded in DECISIONS-LOG: - R-ENV-02 is violated in the base — dev LAN addresses hardcoded into base manifests (cilium k8sServiceHost, the Cilium LB pool, crafty/UniFi LB IPs, 3 S3 backup endpoints). Prod is on 192.168.2.x, so prod would build WRONG today. - clusters/prod never sets GATEWAY_VIP -> would inherit the base default 10.73.0.240, an address on the RETIRED libvirt network. - No NOPASSWD sudo on the prod node -> all Ansible fails at its first become. - node_baseline device defaults are virtio (/dev/vdb,vdc) and absent on bare metal. - ESCALATION: agents/task-board.md is structurally unmaintainable — AGENTS.md designates it the one agent-editable surface, but ci/spec-immutability.sh fails the gate on ANY spec-repo dirt with no path exception. Explains the all-todo board after six phases. NOT worked around: exempting it would weaken an R-TEST-06 gate. Operator decision. Operator decisions: Phase 7 open (prep only); wait for all 3 nodes before cluster-init; check drive health before choosing the single-SSD disk layout. Serves: R-ENV-01, R-ENV-02, R-ENV-03, R-PLAT-01/03. Task: T-7.1. Gate: MERGE GATE: PASS.

Options for the operator/architect: + +- **(a) Preferred** — the human commits board updates in the spec repo, and the impl repo adopts each + via a reviewed `ci/SPEC_PIN` bump. That is exactly the flow `SPEC_PIN`'s own comment describes, and + it keeps both the board truthful and the gate honest. Cost: a pin bump per board update. +- **(b)** Amend `spec-immutability.sh` to exempt `agents/task-board.md` only. Lower friction, + but it narrows an immutability gate — a **human** decision, not an agent's. +- **(c)** Formally declare `DECISIONS-LOG.md` the board of record and retire the spec board.

From e3c44368c84bf2a50ccabc9fb8fe1d0d3ffc42db Mon Sep 17 00:00:00 2001 From: Keith Jackson Date: Mon, 31 Aug 2026 22:29:39 -0500 Subject: [PATCH 02/16] docs(prod): correct sudo posture to vaulted become; record status-surface ruling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two operator corrections: 1. PROD DOES NOT GET NOPASSWD SUDO. My initial checklist recommended mirroring dev's passwordless sudo onto prod — rejected, correctly. Dev's NOPASSWD is a convenience that must not propagate to production. Prod instead keeps a real sudo boundary and drives Ansible `become` with an ansible-vault-encrypted `ansible_become_password` in inventory/group_vars/k3s_prod/vault.yml, mirroring the EXISTING hypervisor and proxmox_hosts groups. The decrypting passphrase stays outside the repo at ~/.config/home-k3s/ansible-vault-pass (ansible.cfg :: vault_password_file), so plays still run unattended with no plaintext secret in git. 2. THE TASK BOARD IS NOT THE STATUS SURFACE — THE REPOSITORY IS. Operator ruling closes the escalation raised in the previous commit. Requirement/spec status is to be DERIVED from repo state (what is authored, reconciled, and covered by a green requirement-tagged test), not from a hand-maintained board. The spec board is left as a historical seed; no agent edits it and no SPEC_PIN churn is spent on it. ci/spec-immutability.sh keeps its full strictness — no path exception was added, since weakening an R-TEST-06 gate for a bookkeeping file would be a defect, not a fix. A repo-derived spec status report becomes the artifact of record alongside the coverage report and this log. Serves: R-ENV-03 (prod provisioning posture), R-SEC-01 (no plaintext secrets), R-TEST-06.

In fact dev LAN addresses were hardcoded into base manifests, so clusters/prod would have come up ANNOUNCING DEV ADDRESSES (192.168.1.x) on the prod LAN (192.168.2.x). New cluster-vars knobs (base default = dev literal, per the file's existing convention): K3S_API_HOST platform/cilium/helmrelease.yaml (+ the values.yaml mirror) CILIUM_LB_POOL_START platform-config/cilium/l2-ip-pool.yaml CILIUM_LB_POOL_STOP " UNIFI_L4_VIP apps/vms/unifi/50-service-l4.yaml CRAFTY_L4_VIP platform/crafty/service-l4.yaml S3_BACKUP_ENDPOINT platform/keycloak/postgres-cluster.yaml, apps/wave-0/{nextcloud, semaphore}-db.yaml, and platform/velero/helmrelease.yaml Also fixes GATEWAY_VIP's base default, which was still the RETIRED libvirt address 10.73.0.240, and adds the GATEWAY_VIP patch that clusters/prod was missing entirely. clusters/base/apps-vms.yaml gains postBuild.substituteFrom (it was the one consuming Kustomization without it, so a ${TOKEN} there would have shipped as a literal string). The envsubst contract is documented there: ${VAR} substitutes and escapes as $${VAR}; $VAR and $(cmd) are left alone; ${ARR[0]} hard-errors. The three UOS_URL expansions in the unifi cloud-init are escaped accordingly. PROD ADDRESS PLAN (operator, 2026-08-31): nodes .10/.11/.12 · control-plane VIP .9 (Ansible-side) · GATEWAY_VIP .20 Cilium LB pool .20-.30 CONTAINMENT INVARIANT, now documented at the pool and in the prod overlay: GATEWAY_VIP MUST equal CILIUM_LB_POOL_START. The shared Gateway pins no address, so Cilium LB-IPAM gives it the first free address of a matching pool block. An initial prod proposal put .20 outside a .21-.30 pool; the Gateway would have come up on .21 while split-horizon coredns-custom kept answering *.home.keithjackson.dev with .20 — an address nothing announces — blackholing in-cluster OIDC hairpin traffic while reporting healthy. The pool was widened to .20-.30. The control-plane VIP (.9) stays outside the pool so kube-vip and LB-IPAM can never contend. Values prod still cannot know stay INVALID `TBD-PROD-*` placeholders on purpose: base defaults are dev values, so an omitted patch means prod silently inherits a dev address — far worse than a loud failed apply. DEV IS BYTE-IDENTICAL. Verified by kustomize build over 13 paths before/after, then flux envsubst with the dev cluster-vars values applied to both sides: zero drift. The only deltas are the intended additive keys in the overlay ConfigMap itself. No unresolved ${TOKEN} survives. render-golden green (10 goldens); yamllint clean. Serves: R-ENV-02.

BECOME: prod does NOT get dev's NOPASSWD sudo. Prod keeps a real sudo boundary and supplies the password to Ansible as an ansible-vault-encrypted `ansible_become_password` in inventory/group_vars/k3s_prod/vault.yml, mirroring the existing hypervisor and proxmox_hosts groups. The decrypting passphrase stays outside the repo (~/.config/home-k3s/ansible-vault-pass), so plays still run unattended with no plaintext secret in git. Committed here: README.md + vault.yml.example only — the operator creates the encrypted vault (`ansible-vault create`), as with every other vaulted group. PACKAGES BELONG IN THE ROLE (operator ruling): smartmontools is now declared in node_baseline_packages, not hand-installed on a node. Drive health tooling is a permanent part of a bare-metal node's baseline — dev nodes are VMs and never needed it. Same click-ops-never principle as the rest of the repo. ADDRESSING: nodes .10/.11/.12, reached DIRECTLY on the LAN (no pfSense NAT hop, unlike dev's 192.168.2.102:225x mapping), so ansible_host is the real node IP. kube-vip control-plane VIP is 192.168.2.9 — deliberately BELOW the nodes and OUTSIDE the Cilium LB pool (.20-.30) so kube-vip and LB-IPAM can never contend for an address. The ingress Gateway VIP (.20) and the LB pool are Flux/cluster-vars concerns and deliberately do not appear in Ansible. BLOCKED-BY-DESIGN: node_baseline_longhorn_device / node_baseline_etcd_device are present but set to an obviously invalid /dev/BLOCKED-... path pending the operator's disk-layout decision (node 1 is a single SATA SSD; the role's /dev/vdb,/dev/vdc defaults are virtio names that do not exist on bare metal). Leaving them unset would silently fall back to those equally-nonexistent defaults — a confusing failure that looks like a wiring bug. This fails just as hard and says exactly why. KNOWN FOLLOW-UP: roles/k3s_server and every node-host playbook hardcode the literal group names k3s_primary/k3s_secondary/k3s_servers, so the k3s_prod_* groups are not selected by them as-is. Harmless now (nothing can accidentally run against prod) but the "same roles, unchanged" reuse R-ENV-02 promises needs the target group parameterized before §6 of PROD-PROVISIONING.md can execute. Documented in hosts.ini and both READMEs. Serves: R-ENV-01, R-ENV-03, R-SEC-01. Task: T-7.1. Gate: MERGE GATE: PASS.

This is that report. conformance/lib/status.py (stdlib-only, --selftest) sits beside lib/coverage.py and IMPORTS it rather than forking the registry/test parsers. Driven by a new `conformance/run.sh --status`; artifacts land in _artifacts/status/ alongside coverage and are git-ignored by the existing convention. Exit codes follow ci/lib.sh (0/1/3); --strict-coverage also applies the status hygiene gate. Signals derived per requirement: is there an implementing artifact; is it RECONCILED (walk resources: from clusters/dev, expand each Flux Kustomization's spec.path, recurse — so a commented-out resource correctly does not count); is there a tagged test and is its body executable or a TODO scaffold (TODO markers OUTRANK an executable: "true" annotation — ambiguity never upgrades a row). DELIBERATELY NOT DERIVED, and reported as such rather than defaulting to green: proof-of-pass (nothing tracked in git records a run result — _artifacts/ and results/ are git-ignored) and cluster liveness. "Reconciled" means Flux WOULD apply it, not that it is healthy. PROVEN is reported as "not derivable" for all 51. WHAT IT SHOWS THAT coverage.md DOES NOT. Coverage reports 37/51 covered, 0 safety-critical gaps. Three of those claims do not survive repo state: 1. 5 of the 37 "covered" requirements have only a TODO-body scaffold (R-STATE-03, R-OBS-02, R-OBS-04, R-GITOPS-03, R-GITOPS-02). Coverage counts a tagged file; it never looks inside it. 2. R-STATE-03 is SAFETY-CRITICAL and its L3 fault test asserts nothing. Coverage reports "0 safety-critical gaps" only because dr-restore/chainsaw-test.yaml exists and carries an L3 label. --strict now fails on this. 3. R-UPD-01/02/03 are NOT reconciled: platform/image-automation/ is commented out of platform/kustomization.yaml. Coverage shows them covered with executable L3 tests, which reads as delivered; automated updates are actually 0/3 wired+testable. Headline: 51 requirements | reconciled 20 (+12 partial) | executable test 32 | wired+testable 22 (+8 partial) | scaffold-only 5 | PROVEN 0 (not derivable). Also surfaces 18 requirements with no reconciled manifest citing their R-ID — listed as a traceability gap (R-TEST-04) rather than guessed either way. Annotating those manifests makes the report self-correct, so it acts as a forcing function instead of another hand-maintained map. Serves: R-TEST-01..06. Gate: MERGE GATE: PASS.

This is that role; the run's findings are below. roles/node_health is a read-only sibling to cluster_verify (cluster health vs hardware health), styled after node_baseline. One unprivileged collector script does the work in a single SSH round trip — reading /sys/class/dmi, thermal + hwmon, EDAC, cpufreq + thermal_throttle, /proc/pressure, /sys/block incl. SCSI ioerr/iotmo counters, lsblk, lscpu, mounts + statvfs, per-NIC stats, resolv.conf. THE DESIGN POINT: an unreadable field is emitted as null WITH A RECORDED REASON, never as zero. The summary ends with a "NOT READ (and why) — these are UNKNOWNS, not passes" section. A fake zero on a reallocated-sector count is exactly the kind of false green this project refuses. 22 checks report PASS/WARN/FAIL/SKIP/INFO; every SKIP says why. Report-only by default; thresholds live in defaults/main.yml. Portable across bare metal AND VMs — validated against k3s-prod-1 (bare metal, no root) and k3s-dev-1 (VM, root). VM-absent things (SMART on virtio, coretemp, EDAC) skip cleanly, and iSCSI/Longhorn volumes are split out of the physical-disk set so a live replica is never mistaken for a spare device. playbooks/node-health.yml takes its target group as a variable (-e node_health_hosts= k3s_prod), deliberately unlike the other playbooks that hardcode k3s_servers — see the group-name gap already flagged in hosts.ini. Two become facts found the hard way and documented in the role: a group_vars `ansible_become: true` OUTRANKS `become: false` as a play/task keyword, so unprivileged tasks must override the variable; and `failed_when: false` does NOT catch "Missing sudo password" — only `ignore_errors` does. FIRST RUN, k3s-prod-1, 2026-08-31: 0 FAIL · 3 WARN · 12 PASS · 3 SKIP · 4 INFO. Box is healthy, cool and unstressed: i7-9700T 8C/8T, VT-x + /dev/kvm (KubeVirt OK), zero throttle events, hottest sensor 33C, PSI 0.00 across the board, 31.1 GiB RAM, eno1 up at 1000 Mb/s, BIOS R21 02.26.00, no reboot pending. DRIVE HEALTH IS STILL UNKNOWN — the headline. SMART did not run, blocked TWICE over: no vaulted ansible_become_password for prod, AND smartmontools is not on the node at all (node_baseline has never run there). Power-on hours, wear, reallocated/pending sectors and drive temperature all remain unmeasured on a ~2011 consumer SSD. WARNs: kernel ioerr_cnt=6 on sda (read cautiously — four freshly attached iSCSI disks on dev each showed a flat 7, suggesting a fixed per-device discovery cost, not media trouble; attribution needs dmesg/root); 0.95 GiB swap still active (node_baseline does the swapoff); one IPv4 resolver only (the other two upstreams are IPv6 Google), which refines rather than resolves the DNS-SPOF finding. ESCALATION — ECC status is UNKNOWABLE on this hardware: /sys/devices/system/edac/mc exists but no controller is bound. Non-ECC consumer RAM. Silent memory corruption on a prod node would be undetectable. Recorded as a SKIP with reason, not a pass. Serves: R-ENV-01, R-ENV-03, R-OBS-04. Task: T-7.1.

From: Keith Jackson Date: Mon, 31 Aug 2026 23:26:49 -0500 Subject: [PATCH 09/16] fix(ci): kill the false-green base resolution; cover R-SEC-01/02 + R-TEST-06 (L0) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Unblocks the enforced Gitea gate, which correctly BLOCKED this branch on ['R-SEC-01','R-SEC-02','R-TEST-06'] being touched but uncovered. Tests were authored; the coverage rule was NOT narrowed. === THE FALSE GREEN (root cause) === `make -C ci gate` locally reported PASS having checked NOTHING. resolve_base() validated nothing, and EVERY way of failing to find a base degraded silently to an empty touched set + exit 0: an `HEAD~1` last resort, a two-dot diff fallback masking a failing three-dot diff, and no check that HEAD is even AHEAD of the base. Run while sitting on `main` (main == origin/main), `origin/main...HEAD` is empty -> "no changed files vs base" -> the empty set means run.sh is invoked with NO --requirements -> coverage.py's --require gate never runs at all. Green by vacuum. Now: candidates are BASE_REF > GITHUB_BASE_REF > origin/main > main, each verified to resolve. HEAD~1 and the two-dot fallback are gone. Unresolvable base / no merge base / failed diff / HEAD-not-ahead -> loud banner, EMPTY stdout, exit 3, and a machine-readable reason (on-base | no-base | diff-failed). gate.sh turns exit 3 into an UNDECIDED decision: `on-base` -> "NOT APPLICABLE — no branch under gate" (exit 0 so push-to-main runs don't break, but it never reads as PASS); `no-base`/`diff-failed` -> BLOCKED. It also now prints the diff base it used. A stale local main warns (widens, never falsely greens). Also fixed `make -C ci test`, which was SWALLOWING failing suites. Regression: ci/tests/touched-requirements-base.test.sh — 31 assertions over 8 throwaway-repo scenarios including the exact false-green case, an already-merged branch, no base ref, a single-commit repo, bogus BASE_REF, a shallow GITHUB_BASE_REF, and origin/main-preferred-over-stale-main. === NEW L0 STATIC LAYER (conformance/tests/l0-static/) === Where docs/14 actually puts these invariants. Each check.sh really executes offline via `run.sh --layer l0` and is wired into ci/l0.sh, so it runs on every PR. No scaffolds. R-SEC-01 no-plaintext-secrets (165 assertions / 445 tracked files): .sops.yaml holds only PUBLIC age recipients; every committed Secret is SOPS-wrapped with a mac and ENC[...] values; ansible vault.yml files are $ANSIBLE_VAULT; no secret-valued ansible key carries a literal outside a vault; no PEM key / age secret key / kubeconfig client-key-data is tracked; Flux declares sops decryption; the disallow-plaintext-secrets policy Enforces and has a proving `result: fail` row. Exemptions are SELF-POLICING, not path allowlists — a .example must be referenced by no kustomization and hold only placeholders, and the Kyverno fixture is exempt ONLY while a test asserts the policy rejects it. Proven against 7 injected violations, including deleting the negative row and weakening Enforce->Audit. R-SEC-02 least-privilege-rbac (41 assertions): no wildcard apiGroup/resource/verb and no escalate|bind|impersonate in any in-repo Role/ClusterRole; no ServiceAccount bound to cluster-admin or a wildcard role; the conformance runner's own test identity is scoped and holds no rights over RBAC objects; the default-deny/host-namespace/egress-class policies Enforce and each carry a negative row. Proven against 6 injected violations. R-TEST-06 spec-immutability-enforced (16 assertions): drives the REAL ci/spec-immutability.sh against HERMETIC throwaway spec repos and asserts its exit code in every state — clean-at-pin 0, edits under docs/ or decisions/ 1, untracked addition 1, unadopted drift 1, explicit pin bump 0, ABSENT spec repo 3 (honest skip, never green), unpinned SPEC_PIN 1 — plus that gate.sh sets BLOCK=1 on its failure, so the mechanism is load-bearing. The real spec repo is never written to. Each check documents what it does NOT cover (runtime decryption, git history, runtime least-privilege, branch protection) rather than overclaiming. status.py now reads check.sh too, so a placeholder L0 body still outranks an `executable: true` annotation. Coverage 37/51 -> 40/51 (11 gaps); executable tests 32 -> 35; scaffold-only stays 5 — no sixth scaffold was added. Serves: R-SEC-01, R-SEC-02, R-TEST-01..06.
