jakman85andClaude Opus 5 161430d915 feat(backup): the overlay picks the credential — BACKUP_CREDENTIALS_SUFFIX
The previous commit created the two halves. This one wires the choice, so dev renders MinIO
credentials and prod renders R2 credentials from the SAME base manifests (R-ENV-02: the
overlay patch is the entire difference between environments; no base manifest is forked).

    cluster-vars  BACKUP_CREDENTIALS_SUFFIX   base ""  |  dev ""  |  prod "-prod"

    velero HelmRelease  credentials.existingSecret: velero-cloud-credentials${BACKUP_CREDENTIALS_SUFFIX}
    3x CNPG Cluster     s3Credentials.*.name:      <db>-backup-credentials${BACKUP_CREDENTIALS_SUFFIX}

ONE SUFFIX, NOT FOUR SECRET-NAME KNOBS. Four independent knobs can be updated three-quarters
of the way, leaving one consumer reading the OTHER environment's key with nothing rendering
wrong — and StrictPostBuildSubstitutions cannot catch that: strict mode fails on an UNDEFINED
variable, never on a defined-but-stale one. With one suffix the four move together or not at
all. The cost is that the rendered Secret name is not greppable from the consumer, so both
kustomizations spell the two names out in full beside the resources.

THE BASE DEFAULT IS "" AND THAT IS LOAD-BEARING. It renders the UNSUFFIXED names — objects
that exist in every render, and that dev is running today. The alternative failure mode is
strictly worse than the shared-Secret state this replaces: velero's pod hangs in
ContainerCreating forever when `existingSecret` names a missing Secret (the volume never
mounts), and a CNPG Cluster whose s3Credentials Secret is absent stops archiving WAL — which
under archive_mode=on is a filling pgdata PVC, not a missing backup. So an unresolvable
default breaks the referencing cluster HARDER than a wrong key does. Both overlays state the
value explicitly anyway, so neither inherits it silently.

Prod's overlay change is a cluster-vars op only. The velero Flux Kustomization patch is
untouched (it stays decryption-only, and velero stays suspended on prod).

VERIFIED — `kubectl kustomize --load-restrictor LoadRestrictionsNone` on clusters/dev and
clusters/prod for the cluster-vars values, then on each of the four affected tiers (platform,
platform-config, platform/velero, apps/wave-0) piped through `flux envsubst --strict` with
that environment's variables:

  strict envsubst              PASSES for all 8 (env x tier) combinations
  dev   velero existingSecret  velero-cloud-credentials
  dev   keycloak/nextcloud/semaphore-db  <db>-backup-credentials         (both key refs each)
  prod  velero existingSecret  velero-cloud-credentials-prod
  prod  keycloak/nextcloud/semaphore-db  <db>-backup-credentials-prod    (both key refs each)
  both  all EIGHT Secret objects present in the rendered output (dev and prod alike)
  no `${...}` survives in any rendered tier except gitea's three DELIBERATE `$${...}` shell
    escapes in apps/wave-0, which are pre-existing and unrelated.

Read alongside the endpoints the same overlays already set, the two environments are now
isolated on credential AND target:
  dev   velero s3://velero (root) + cnpg s3://cnpg      @ http://192.168.1.9:9000  region us-east-1
  prod  velero k3s-prod-backup/velero + barman prefix   @ https://<acct>.r2.cloudflarestorage.com  region auto

# clusters/prod — DESIGN-ONLY overlay. NOT a build target until roadmap Phase 7 opens prod
# (spec roadmap/phases.md, AGENTS.md §6: "Never build directly on production").
#
# When Phase 7 is opened, `flux bootstrap ... --path=clusters/prod` points the prod cluster's Flux
# here. Like dev, this overlay adds NO resources — it ONLY patches cluster-vars with prod-scoped
# values (R-ENV-02). Promotion to prod is a change to THESE variables, never a base edit.
#
# *** PHASE-7 BLOCKER — READ BEFORE BOOTSTRAPPING PROD ***
# `clusters/base/platform.yaml` now carries `dependsOn: [flux-system]` (the 2026-09-01 substitution-
# race fix). That names the ROOT Kustomization, which clusters/dev supplies as `dev/sync.yaml`
# (path ./clusters/dev). THIS overlay has no sync.yaml yet, so as written a prod bootstrap would
# leave `platform` stuck on "dependency 'flux-system/flux-system' is not ready" FOREVER and nothing
# downstream would reconcile. Phase 7 MUST add `clusters/prod/sync.yaml` — a copy of dev/sync.yaml
# with `path: ./clusters/prod` — as part of opening this overlay. (Adding it now is deliberately NOT
# done here: prod is design-only and its root object is the prod bring-up owner's call.)

#
# ############################################################################################
# ### ###
# ### *** T E M P O R A R Y B O O T S T R A P S O U R C E — NOT PERMANENT *** ###
# ### ###
# ### The url below is a Gitea container running ON THE OPERATOR'S WORKSTATION, outside ###
# ### any cluster. It exists ONLY to get prod's first reconcile off the ground. It MUST ###
# ### be cut over to the in-cluster URL once Gitea runs on prod. If you are reading this ###
# ### and prod has been serving traffic for months, THE CUTOVER WAS NEVER DONE — that is ###
# ### a live single point of failure, not a settled design. See "CUTOVER" below. ###
# ### ###
# ############################################################################################
#
# WHY THE IN-CLUSTER URL CANNOT BE USED YET (blocker found 2026-09-01, still true; the
# unusable value was `https://gitea.home.keithjackson.dev/Home-Network/home-network-k3s-impl.git`).
# Two independent reasons, both consequences of the split-horizon design:
# 1. SELF-HOSTING CIRCULARITY. Gitea runs ON THE DEV CLUSTER. Prod syncing from it means prod's
# GitOps source lives inside the very cluster slated for decommission. Gitea must move to
# prod (or off-cluster) BEFORE dev is retired, or prod loses its source of truth.
# 2. SPLIT-HORIZON DNS SENDS IT TO THE WRONG PLACE. platform/coredns/coredns-custom.yaml
# answers the ENTIRE home.keithjackson.dev zone with ${GATEWAY_VIP}. On prod that is
# 192.168.2.20 — PROD's own gateway, where no Gitea is listening. Prod's Flux would resolve
# gitea.home.keithjackson.dev to itself and never reach a repository.
#
# WHAT THE TEMPORARY SOURCE IS (stood up 2026-09-04 on explicit operator direction):
# bootstrap/gitea/bootstrap-gitea.sh with HOST_NAT_IP=192.168.2.132 — a podman container on the
# operator's workstation, Gitea 1.22.6, listening on 192.168.2.132:3000. All three prod nodes
# reach it DIRECTLY on the LAN: no libvirt NAT hop (that network is retired) and no firewall
# change was needed. This is the same "local bootstrap source" pattern dev itself used before
# its Phase-6 cutover (docs/05 "Source-of-truth").
#
# PLAIN HTTP, AND WHY THAT IS ACCEPTED HERE: the bootstrap Gitea has no TLS, so there is no cert
# for Flux to trust and no caCertSecretRef to wire. Traffic is LAN-local between prod nodes and
# the workstation, the repo carries NO plaintext secrets (everything sensitive is SOPS-encrypted,
# .sops.yaml), and the window is the bring-up only. Do NOT extend this posture past cutover.
#
# NO secretRef, DELIBERATELY: the repo is PUBLIC on the bootstrap Gitea, so anonymous clone
# works and Flux needs no git credentials. VERIFIED 2026-09-04 by unauthenticated request:
# curl http://192.168.2.132:3000/api/v1/repos/Home-Network/home-network-k3s-impl -> "private":false
# git ls-remote http://192.168.2.132:3000/Home-Network/home-network-k3s-impl.git -> refs/heads/main
# If the GitRepository ever reports an auth failure that looks like a network problem, RE-CHECK
# THAT FIRST: a private repo here fails exactly that way.
#
# *** CUTOVER — the exit condition, mirroring dev's Phase-6 cutover (docs/05) ***
# WHEN: Gitea runs on prod (reconciled in-cluster) and answers gitea.home.keithjackson.dev
# through prod's own Gateway VIP with a publicly-trusted cert.
# DO: 1. push/mirror this repo into the prod in-cluster Gitea;
# 2. change the url below to
# https://gitea.home.keithjackson.dev/Home-Network/home-network-k3s-impl.git
# and DELETE this whole TEMPORARY block (dev's equivalent stanza, ~15 lines above in
# clusters/dev/kustomization.yaml, is what "done" looks like);
# 3. confirm `flux get sources git -n flux-system` reconciles the new revision;
# 4. only THEN stop the workstation container. Keep it stopped-not-deleted as recovery,
# exactly as dev retained its bootstrap Gitea.
# UNTIL THEN: prod's reconciliation depends on a container on a workstation that may be
# powered off. Flux keeps the last-reconciled state running, but NO new revision lands while
# it is down. Tracked as an open blocker in infra/PROD-PROVISIONING.md §7.
#
# The BRANCH below is settled and correct: prod tracks `main`, the same branch as dev.
# CONSEQUENCE, recorded deliberately: once prod is live, EVERY MERGE TO main RECONCILES BOTH
# CLUSTERS. There is no promotion step and no soak window — dev and prod move together.
# NOTE for bring-up: bootstrap-gitea.sh pushes the operator's CURRENT HEAD to the bootstrap
# Gitea's `main`, whatever branch that is. Before bootstrapping prod, confirm that remote `main`
# is the revision you intend prod to run (`git ls-remote` above, against local `main`).

# CUTOVER DONE 2026-09-06 (operator direction: "move the repo to prod"). Prod now reconciles

# PROD SERVES ITS OWN SUBDOMAIN. Until 2026-09-04 every hostname was HARDCODED to
# home.keithjackson.dev in the base manifests, so prod was authored to serve the EXACT SAME
# public names as the live dev cluster out of the SAME Cloudflare zone. Two consequences, one
# of which already happened:
# 1. HAPPENED: prod's external-dns (policy: sync, owner id `default` — the same implicit
# default dev had) concluded it owned dev's records and DELETED EVERY ONE of them.
# 2. QUEUED BEHIND IT: platform-config would have requested a `*.home.keithjackson.dev`
# wildcard from letsencrypt-prod for a cert dev already holds, and both clusters would
# have raced each other's `_acme-challenge` TXT records on that one zone.
# Moving prod to its own suffix dissolves both: the two clusters can no longer name the same
# record. This is what makes ACME_CLUSTER_ISSUER: letsencrypt-prod above safe here.
#
# dev -> home.keithjackson.dev (UNCHANGED — dev is live; phase 2 moves it)
# prod -> prod.home.keithjackson.dev (this knob)
#
# CONSEQUENCE — prod's hostnames are NOT the apex names. Prod's Gitea is
# gitea.prod.home.keithjackson.dev, its Keycloak keycloak.prod.home.keithjackson.dev, and so
# on; the wildcard cert becomes `*.prod.home.keithjackson.dev`. The apex CNAMEs that make

# ZONE selection too, and on the version in use in 2026-08 a strict-subdomain filter dropped
# the parent zone ("no hosted zone matching record DNS Name"). If prod's external-dns logs no
# matching zone, it will create NOTHING — fail-closed, and it can still never delete dev's

# Dev's versitygw/MinIO (192.168.1.9:9000) sits on the DEV side of the network and is NOT an
# option for prod, for two independent reasons:
# 1. UNREACHABLE. Prod is on the SOHO network 192.168.2.0/24 — pfSense's WAN — while that
# MinIO is inside pfSense's LAN. Measured from a pod INSIDE prod (the workstation proves
# nothing about pod egress): `curl http://192.168.1.9:9000/minio/health/live` → connection
# timed out after 15s. Reaching it would need a WAN→LAN rule that does not exist.
# 2. NOT OFF-CLUSTER DR. It runs on the same Proxmox host as dev's VMs, so it already shares
# a physical failure domain with dev. R2 is genuinely off-site, and its free egress means
# restore REHEARSALS cost nothing — R-STATE-03 has no financial disincentive to stay proven.
#
# THIS UNBLOCKS AN ACTIVE INCIDENT, not just a roadmap item. All three prod CNPG Clusters ship
# `archive_mode=on` with `endpointURL: TBD-PROD-S3-BACKUP-ENDPOINT`, so barman-cloud-wal-archive
# exits 4 on every segment and Postgres — correctly — REFUSES TO RECYCLE WAL. Verified live

# ContinuousArchiving=False/ContinuousArchivingFailing, and keycloak-db's 5 GiB PVC is at
# 579 MiB used / 4360 MiB free and climbing monotonically. A disk-full PANIC there takes the
# cluster's SSO database down, and with it kubectl OIDC, Grafana, Headlamp, Gitea and
# forward-auth. Fixing the endpoint lets Postgres drain the whole backlog.
#
# ENDPOINT IS ACCOUNT-SCOPED, so it stays a prod-overlay value even though it is not a LAN
# address: this is the operator's Cloudflare account id, confirmed from inside a prod pod
# (`head-bucket` on k3s-prod-backup → BucketRegion WNAM; PUT and DELETE both succeed).
# It is NOT put in base, because base is dev's live MinIO and dev is deliberately STAYING
# there — moving dev to R2 would reset its PITR window and orphan the backups its PROVEN
# restore depends on. Two environments, two targets, isolated by URL *and* by bucket.

# OBJECT TENANCY INSIDE THE ONE BUCKET. The operator created a SINGLE R2 bucket, so velero and
# barman cannot be separated by bucket the way they are on dev's MinIO (`velero` and `cnpg`).
# They are separated by disjoint TOP-LEVEL PREFIXES instead:
#
# s3://k3s-prod-backup/velero/… Velero: kopia repo + backup metadata
# s3://k3s-prod-backup/barman/<clusterName>/… CNPG: WAL + base backups
#
# The bucket ROOT is left empty on purpose — a misrendered prefix then lands somewhere
# obviously wrong instead of silently colliding with a live tenant. Velero's retention TTL
# deletes objects under its own prefix only, so it can never reap a WAL segment; and barman's
# per-cluster serverName subdirectory keeps the three Postgres servers' chains apart, which
# matters because interleaving two servers' WAL into one prefix corrupts the chain outright.
# Dev cannot be reached from any of these: different endpoint AND different bucket names.

# WHICH CREDENTIAL SIGNS THE REQUESTS TO THAT BUCKET (per-env credential split, 2026-09-07).
# ------------------------------------------------------------------------------------------
# The knobs above moved the ENDPOINT and the OBJECT LAYOUT per environment. The credential did
# not move with them, and it could not: the four backup-credential Secrets are SHARED BASE
# manifests, applied to both clusters by the same Flux tiers. Writing the R2 token into them
# gave prod a working key by TAKING DEV'S AWAY — dev would have signed MinIO requests with an
# R2 key id, and under archive_mode=on that is a filling pgdata PVC, not a missing backup.
#
# So each credential is now two objects, and this suffix selects prod's:
# velero-cloud-credentials-prod the R2 token in the AWS INI `cloud` shape
# <db>-backup-credentials-prod the same token as ACCESS_KEY_ID / ACCESS_SECRET_KEY
# for keycloak-db, nextcloud-db and semaphore-db. Both halves ship to both clusters (they are
# base resources); ONLY this value decides which one each consumer reads. It is a SUFFIX rather
# than four secret-name knobs deliberately — four could be updated three-quarters of the way,
# leaving one consumer on dev's MinIO key with nothing rendering wrong, and strict-mode
# substitution cannot catch a defined-but-stale variable.
#
# THE R2 TOKEN IS THE ONE PROVEN FROM INSIDE PROD (chore/r2-credentials 0a6a862): head-bucket on
# k3s-prod-backup returns BucketRegion WNAM, and PUT and DELETE both succeed. Rotating it now
# touches ONLY the four `-prod` files; dev's MinIO keys are untouched objects. That isolation is
# the structural reason for the split, independent of dev's eventual decommission.
