Myasnikov Daniil ca7d2b0182 docs(platform): explain system component memory limits
Add docs/operations/system-memory-limits.md, recording why system
components carry memory limits. That reasoning is not recoverable from
the values themselves, and is exactly the kind of thing a well-meaning
later change removes as redundant.

The Talos userspace OOM handler (v1.12+, enabled by default) selects
its victim by ranking cgroups that lack memory.max. Three consequences
are each easy to get wrong on their own: only a limit grants immunity,
since a request merely moves BestEffort to Burstable and under
strictCgroupClassOrdering that means "killed second"; every container
in the pod needs one, init containers included, because kubelet sets
pod-level memory.max only when all of them have it; and PriorityClass,
system-node-critical included, has no bearing on it whatsoever,
because the handler walks cgroupfs and holds no Kubernetes client.
That last one is the trap, since setting a priority looks like a fix.

The page also covers the two installer knobs and the constraint that
makes them dangerous to lower (a defaulted limit below a container's
own request fails admission), how to confirm a pod cgroup really
carries memory.max rather than trusting the QoS class, what is
deliberately left uncovered, and how to relax the global-PSI backstop
clause of the trigger on a cluster that trips it persistently.

Every Talos claim is checked against the siderolabs/talos v1.13.6 tag,
which is the version packages/core/talos currently ships, and every
Cozystack claim against the tree.

Ordering: this documents behaviour introduced by the system-namespace
LimitRange and the node-DaemonSet resource changes, so it should not
merge ahead of them.

Andrey Kolkov b496fb1ae8 docs(backups): note to-copy MongoDB restore needs target creds that can read the source bucket
A to-copy restore reads the dump from the source backup's bucket/endpoint but
authenticates with the target cluster's own S3 credentials (the source
release's Secret dies with it in a DR scenario). Document that the target's
credentials must therefore be able to read the source bucket - the common
same-bucket cozy-backups case - and that a cross-account/bucket target fails
loudly with AccessDenied rather than silently restoring nothing.

Addresses the MINOR credential-scoping note from PR review.

Andrey KolkovandClaude Opus 4.8 0d4a3e3134 refactor(backups): make MongoDB PITR option uniform with CNPG + warn on unknown restore options
PITR: replace the bespoke spec.options.pitr{type,date} blob with a single
spec.options.recoveryTime RFC3339 string, matching the CNPG strategy's option
exactly (CNPGRestoreOptions.RecoveryTime). The driver converts recoveryTime to
the psmdb Restore's pitr{type:date,date} in the operator's "YYYY-MM-DD HH:MM:SS"
UTC format. An empty recoveryTime restores the snapshot as-taken (documented
difference from CNPG, whose empty value means latest WAL — a psmdb logical
backup is already consistent). A non-RFC3339 recoveryTime fails terminally.

Unknown options: parseMongoDBRestoreOptions now also returns the set of
spec.options keys the driver does not recognise; reconcileMongoDBRestore emits a
UnknownRestoreOption Warning event per unknown key (and logs it) instead of
silently ignoring it — so a "recoverytime" typo no longer silently degrades a
PITR restore to a snapshot restore. (BackupJob carries no spec.options blob, so
there is no backup-path equivalent; the only backup-time input is the free-form
BackupClass parameters used as template vars.)

Docs + examples updated to recoveryTime; tests cover the RFC3339→UTC mapping,
empty/invalid recoveryTime, and unknown-key reporting.

Andrey KolkovandClaude Opus 4.8 dff56aa998 feat(backups): add a native MongoDB (psmdb) backup-strategy driver
Adds a MongoDB (Percona Server for MongoDB / psmdb) backup-strategy driver so
`apps.cozystack.io/MongoDB` reaches feature parity with the CNPG, MariaDB and
ClickHouse native drivers — logical backups, restore-to-differently-named
instances, and point-in-time recovery through the unified
BackupJob/RestoreJob/BackupClass/Plan interface (closes #3545).

The driver orchestrates the operator's PerconaServerMongoDBBackup /
PerconaServerMongoDBRestore CRDs:

- BackupJob: creates a one-shot PerconaServerMongoDBBackup, polls
  status.state, and persists the S3 destination + storage descriptor
  (by-reference, no credentials) onto the Cozystack Backup artifact.
- RestoreJob: drives PerconaServerMongoDBRestore via backupSource (read back
  from the source backup status, snapshot fallback) so the same artifact
  restores in-place or into a differently-named instance; PITR via
  spec.options.pitr (date/latest).

Because psmdb resolves the backup storage by name against the cluster's
spec.backup.storages, the driver names the chart's storage (s3-storage) via the
cozy-default-mongodb Strategy rather than injecting it, and surfaces a clear
Ready=False precondition when a target has backups disabled.

Wiring:
- api/backups/strategy/v1alpha1: MongoDB strategy type + generated CRD/deepcopy.
- internal/backupcontroller: psmdbstrategy_controller + psmdbtypes/mongodbapp
  partial-schema mirrors; dispatch, supported-kinds and scheme registration.
- backupstrategy-controller: cozy-default MongoDB route, cozy-default-mongodb
  Strategy CR, and psmdb.percona.com RBAC.
- apps/mongodb: backup.insecureSkipTLSVerify knob (psmdb s3 storage has no
  CA-bundle field) so backups can target Cozystack's self-signed seaweedfs.

Tests + e2e:
- unit tests for the driver (validation, ensure-idempotency, precondition,
  backupSource resolution, snapshot round-trip, PITR option parsing).
- examples/backups/mongodb + a mongodb-2-backup-roundtrip Chainsaw suite that
  drives run-all.sh end-to-end (sentinel document round-trips through S3 into a
  restored copy while the source stays untouched), per docs/agents/e2e-testing.md.
- docs/operations/backup-classes.md updated.

Andrey Kolkov d0990299ed feat(clickhouse): let the backup sidecar trust a private S3 CA, unblocking the backup e2e round-trip (#3385)
## What this PR does

Gives the ClickHouse `clickhouse-backup` sidecar a way to trust an S3
endpoint whose certificate is signed by a private CA, and uses that to
make the ClickHouse backup/restore e2e round-trip actually run in CI.
This actualizes #2600, whose feature code and example scripts have since
landed on `main` independently, and whose remaining contribution — the
e2e test — was still in the retired BATS format. #2600 can be closed
once this merges.

### 1. `backup.endpointCA` on the ClickHouse chart

The sidecar had **no TLS/CA surface at all**: bucket coordinates and
credentials arrive as `S3_*` env, and nothing let it verify an endpoint
signed by a private CA. Cozystack's own in-cluster SeaweedFS is exactly
that case — it serves `:8333` behind the self-signed "SeaweedFS CA" — so
a ClickHouse release could only ever back up to a publicly-trusted
endpoint. MariaDB (`storage.s3.tls.caSecretKeyRef`) and Postgres (barman
`endpointCA`) have had a CA field all along; this closes the gap for
ClickHouse.

`backup.endpointCA` takes `{name, key}`. When set, the chart mounts that
Secret into the sidecar and points `SSL_CERT_DIR` at it. Empty — the
default — renders no env, no mount and no volume, so existing releases
are byte-for-byte unchanged.

**Why `SSL_CERT_DIR` and not `AWS_CA_BUNDLE`.** Both are honoured by
`altinity/clickhouse-backup:2.7.4`; I measured them against a
self-signed endpoint and public AWS S3 in turn. Go reads `SSL_CERT_DIR`
*in addition to* the system bundle, so both endpoints verify.
`AWS_CA_BUNDLE` *replaces* the SDK's trust pool: the private endpoint
verifies, and public S3 then fails `x509: certificate signed by unknown
authority` — it would silently break a release that also talks to a
public endpoint. `S3_DISABLE_CERT_VERIFICATION` was rejected outright,
since it drops verification rather than trusting one more CA.

### 2. The e2e suite, and what it was really testing

Two Tests added to the existing `hack/e2e-chainsaw/clickhouse/` suite
(in name order, mirroring the `etcd`/`mariadb`/`postgres` shape — see
the layout rationale below for why they live here rather than in a new
directory):

- **`clickhouse-1-backup-contracts`** (CI, `tenant-test`, ~98s): a
backup-enabled ClickHouse asserted against the *running* cluster — the
`clickhouse-backup` sidecar on the `ch-backup-api` `:7171` port, and the
`<release>-backup-api-auth` Secret whose keys the sidecar's
`API_USERNAME`/`API_PASSWORD` actually resolve `valueFrom`. Each is a
silent break if a chart bump renames it. Needs no object store.
- **`clickhouse-2-backup-roundtrip`** (CI, `tenant-root`): `Bucket` →
`Altinity` strategy + `BackupClass` → source ClickHouse with a sentinel
row → `BackupJob` → in-place `RestoreJob` → to-copy `RestoreJob` into a
second instance, driving `examples/backups/clickhouse/run-all.sh` so
test and docs cannot drift.

The round-trip was originally gated behind `CLICKHOUSE_E2E_S3_ROUNDTRIP`
and **skipped in CI** — its `PASS (1.01s)` meant the gate fired, not
that a backup happened. `backup.endpointCA` removes the reason for the
gate, so the suite now adopts the same three preconditions
mariadb/postgres rely on: run in `tenant-root` (an isolated tenant's
Cilium egress allowlist blocks its Pods from reaching `tenant-root`'s
SeaweedFS), target the in-cluster endpoint instead of the `Bucket`'s
external ingress URL (an unroutable placeholder in CI), and trust its
certificate via the copied CA. It also pre-cleans with `cleanup.sh`,
because `tenant-root` is shared and a leftover `Succeeded` `BackupJob`
would satisfy the harness's wait without a backup ever running.

Both backup Tests live in the existing `hack/e2e-chainsaw/clickhouse/`
suite rather than a new suite directory, so no selector mapping is
added: `hack/select-e2e.sh` already derives `clickhouse` both from
`packages/apps/clickhouse/**` (the `*-application` rule) and from
`examples/backups/clickhouse/**` (the harness path), and both paths
therefore select the suite that actually runs the harness. That
alignment is the reason for the layout — a separate `clickhouse-backup/`
directory would have made an edit to the harness select a suite that
cannot exercise it. `hack/select-e2e.sh` and `hack/select-install.sh`
are otherwise untouched (the only change is a comment recording that
invariant), and the existing `backup example harness edit selects its
app suite` case in `hack/select-e2e_test.bats` covers the mapping.

### Verification

- `helm unittest` — 17 pass, including 5 new `endpointCA` cases: the
unset default renders nothing, the env/mount/volume wiring, a custom key
still projected as `ca.crt`, composition with `useSystemBucket`, and
`backup.enabled=false` renders nothing.
- The CA-trust behaviour was measured against the real image, not
assumed: without a CA knob the sidecar reports `x509: certificate signed
by unknown authority`; with `SSL_CERT_DIR` the handshake succeeds.
- `hack/select-e2e_test.bats` (16) and `hack/select-install_test.bats`
(17) pass; `select-install.sh --validate` reports graph OK.
- `make generate` is idempotent, so the pre-commit job's `git diff
--exit-code` stays clean.
- The contracts Test passed in CI on earlier runs of this branch. The
round-trip only became CI-live with this work, so it still needs a green
E2E run before merge — the branch has since been rebased onto current
`main` to get one.

### Screenshots

Not applicable — no UI changes.

### Downstream repositories

Walked the trigger map against the diff, file by file. The load-bearing
change is the new `backup.endpointCA` field in
`packages/apps/clickhouse/values.yaml` / `values.schema.json`;
everything else is `hack/e2e-chainsaw/`, `examples/backups/`, one docs
paragraph, and regenerated artifacts, none of which appear in the map.

- [ ] No downstream repository is affected by this change
- [x]
[cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack)
- follow-up:
https://github.com/cozystack/terraform-provider-cozystack/issues/18 —
"add, remove or rename a field in an app's `values.schema.json`" reaches
the provider's hand-maintained schema, model and expand/flatten pair, so
the new nested object is not surfaced until it is added there. Opened as
an issue rather than a PR because the natural moment is alongside that
repo's next `api/apps/v1alpha1` pin bump, which is a maintainer call.

Not ticked, with reasons rather than silence: **cozystack/website** —
the trigger is *adding, renaming or removing a package*, and this adds a
field to an existing one. `clickhouse` is already in the website
`Makefile`'s app list and its reference page is generated from this
package's `README.md`, so the regenerated `backup.endpointCA` rows are
carried by the existing release-tag automation with no manual PR.
**cozystack/external-apps-example** — vendors `hack/package.mk` and
`update-crd.sh`, neither of which this PR touches.
**cozystack/ansible-cozystack**, **ccp**, **talm**, **cozyhr**,
**cozy-proxy**, **cozystack-telemetry-server**, **examples** — no
installer values, `hack/` layout, namespace, variant, node-prerequisite,
annotation, label or metric in their trigger rows is touched here.

### Release note

```release-note

Mattia Eleuteri f859b710a4 fix(backupstrategy-controller): repair the bucket credentials Secret from the gate, not a chart fail
Addresses the four findings on #3524.

**The `fail` in the bucket chart (MAJOR).** The <bucket>-<user>-credentials
Secret was made to `fail` the render while its COSI lookup was empty, so the
release would retry and converge instead of skipping the Secret permanently.
Helm cannot render a partial set, so that fail aborts the WHOLE
<bucket>-system release: the other users' Secrets, and the bucket UI
Deployment/Service/Ingress/HTTPRoute with them. One declared user whose
BucketAccess never provisions takes down every other user of that bucket,
and on an already-installed release parks it in Failed, blocking every later
upgrade.

**No per-bucket escape (MAJOR).** Rather than add one, remove the need for
it. The gate already forces the release that renders the lookup-gated
Strategy CRs; the credentials Secret is the same trap one release earlier,
and the gate reads that Secret to resolve the bucket name in the first
place. So while it is absent, or carries no bucket name, force the bucket's
<bucket>-system release instead of doing nothing. That cannot deadlock its
own precondition: the BucketClaim and the BucketAccess whose COSI Secret the
lookup reads are rendered unconditionally by the parent release, not by the
one being forced.

The two releases are throttled independently — they are forced in sequence
on a bootstrap, so a shared timestamp would delay the second by a full
MinForceInterval for no reason. Coordinates come from the chart under
provisionBucket, and are omitted on external S3 where the Secret is
admin-managed and no release renders it. No RBAC delta: patch on
helmreleases is already cluster-scoped.

The chart goes back to a partial render, with the comment now explaining why
the skip is not self-healing and why failing is the wrong lever, and a test
that renders the UI with every user unresolvable so a reintroduced `fail`
fails the suite. Tenant buckets keep their pre-existing behaviour;
generalising the repair to every bucket needs a controller that owns them
and is tracked separately.

**Stale gauge (MINOR).** cozystack_backup_default_objects_missing was only
written on the happy path, so the state the gate exists to catch reported 0
and the documented alert never fired. It is now written on the unresolved
path too — the credentials Secret counts as one of the objects the default
backups depend on, which is what it always was. On an API error the gauge is
deliberately left alone rather than flapping, so a new
cozystack_backup_default_objects_check_errors_total marks it stale, and the
doc pairs the two instead of overstating the gauge.

**Suspended releases (MINOR).** forceHelmRelease now does a point Get and
skips a release with spec.suspend: true. helm-controller ignores forceAt and
requestedAt while suspended (`cozyhr suspend` sets exactly that), so the gate
was re-stamping every MinForceInterval for the whole suspension and climbing
the force counter — which the runbook attributes to a render that is not
producing the objects, the wrong diagnosis. The skip is logged and not
counted, so a climbing counter keeps its documented meaning.

Mattia Eleuteri 51ad226706 fix(backupstrategy-controller): repair lookup-gated backup objects
The default Strategy CRs and the Velero BackupStorageLocation are
Helm-templated behind a `lookup` of the BucketClaim the same chart
creates, and the <bucket>-<user>-credentials Secret behind a `lookup` of
the COSI Secret. When those lookups are empty at install time the objects
were silently skipped, and helm-controller does not re-render a release
whose chart and values did not change (drift detection is off on
operator-generated HelmReleases), so the skip was permanent: clusters ran
for months with only BackupClass cozy-default and no Strategy CRs at all.
That also fail-closes the pre-adoption snapshot in the v1.6.0 etcd
migration, which reads the projected credentials Secret.

Add a DefaultObjectsGate runnable to backupstrategy-controller. Once the
bucket name is resolvable from the projector's source Secret, it checks
that every object cozy-default routes to exists and forces one real Helm
upgrade (reconcile.fluxcd.io/forceAt + requestedAt) when any is missing.
Helm remains the objects' only author; the gate only makes sure the render
that produces them actually happens. It cannot be a render-time `fail` in
this chart: the chart is the producer of the Bucket its own lookup reads,
so a failed render would deadlock the condition.

The bucket chart's user-credentials template CAN fail safely — the
BucketAccess that produces the COSI Secret belongs to the parent release
and that release retries forever — so make it fail loudly instead of
skipping, with requireUserCredentials=false as the offline-render escape.

Also correct the chart and doc comments that claimed Flux re-renders on
its interval, and document the two-release manual recovery for clusters
already affected.

Andrey KolkovandClaude Opus 4.8 2687e095f4 feat(clickhouse): let the backup sidecar trust a private S3 CA
The clickhouse-backup sidecar had no TLS/CA surface at all: bucket coordinates
and credentials arrive as S3_* env, and nothing let it verify an endpoint whose
certificate is signed by a private CA. Cozystack's own in-cluster SeaweedFS is
exactly that case — it serves :8333 behind the self-signed "SeaweedFS CA" — so a
ClickHouse release could only ever back up to a publicly-trusted endpoint, while
MariaDB (storage.s3.tls.caSecretKeyRef) and Postgres (barman endpointCA) have had
a CA field all along.

Add backup.endpointCA {name, key}. When set, the chart mounts that Secret into
the sidecar and points SSL_CERT_DIR at it. Empty (the default) renders no env, no
mount and no volume, so existing releases are untouched.

SSL_CERT_DIR rather than AWS_CA_BUNDLE, measured against
altinity/clickhouse-backup:2.7.4 with a self-signed endpoint and public AWS S3 in
turn: Go reads SSL_CERT_DIR in addition to the system bundle, so both verify;
AWS_CA_BUNDLE replaces the SDK trust pool, so the private endpoint verifies and
public S3 starts failing `x509: certificate signed by unknown authority`. That
would silently break a release that also talks to a public endpoint.
S3_DISABLE_CERT_VERIFICATION was rejected outright — it drops verification
instead of trusting one more CA.

Covered by helm-unittest: the unset default, the mount/env/volume wiring, a
custom key still projected as ca.crt, composition with useSystemBucket, and that
backup.enabled=false renders nothing.

myasnikovdaniil 2c453778f1 fix(seaweedfs): make naming audit fail closed on kubectl and payload errors (#3436)
## What this PR does

Fixes #3431.

`hack/seaweedfs-naming-audit.sh` was fail-open: any kubectl failure
produced an empty table indistinguishable from an honestly clean fleet —
a failed namespace LIST meant zero namespaces walked, failed
secret/PVC/STS LISTs meant zero findings, all silenced by `2>/dev/null`
with no error handling anywhere in the script. The runbook uses this
output as the gate before PVC deletion, as post-deletion verification,
and as an upgrade precondition, so a transient API error could
green-light destroying data.

Every kubectl call now routes through a `run_kubectl` helper: a non-zero
exit prints a FATAL line naming the failed query and the code propagates
up the whole chain (enumerations restructured to capture-then-check,
since an `exit` inside `$(...)` dies with the subshell). By-name GETs
separate existence from extraction: a `--ignore-not-found -o name` probe
keeps legitimate absence (Helm-pruned revision, unbound PVC) a clean
skip, while everything else fails loudly — including a release Secret
that exists but has no decodable payload or decodes without a chart
name, which previously dropped the whole tenant from the audit.
Incomplete PV-age evidence now marks the generation incomplete and falls
to the safe "direction cannot be established" branch, so a failed GET
can no longer flip an OVERLAP verdict into a wrong Step-3 deletion
candidate. A successful audit prints the same bytes as before.

Tests: 14 new cozytest cases — failure injection for every LIST and
by-name GET site, corrupt-payload variants (missing `.data.release`,
undecodable base64/gzip, chartless `{}`), and full-output golden diffs
proving the success paths stay byte-identical to the pre-change script.
25/25 green via `hack/cozytest.sh`.

### Release note

* **Bug Fixes**
* Audits now fail clearly (non-zero exit + fatal messaging) when
Kubernetes queries or Helm release data is unavailable or corrupt,
instead of producing incomplete results.
* Missing release revisions are skipped safely; missing/unreadable PV
age evidence no longer leads to incorrect deletion candidates, and MIXED
now reports conservative “direction cannot be established” when evidence
is incomplete.
  * Non-SeaweedFS releases remain silently ignored.

* **Tests**
* Added end-to-end acceptance coverage for fail-closed behavior and
byte-for-byte stable output across key naming scenarios.

* **Documentation**
* Updated the runbook to require relying on the audit script exit code
before proceeding, with a dedicated MIXED re-check step.

Myasnikov Daniil e02adad38f fix(seaweedfs): read the chart name first-match, fail the fake on unmodelled calls
Review findings from #3436, plus what an adversarial re-check of the first
attempt at them turned up.

The chart-name extraction was a greedy sed, i.e. LAST match. Helm marshals
"config" (the release`s values) after "chart", so a values subtree that spells
chart.metadata.name shadowed the real chart name: the release then read as
non-SeaweedFS, the tenant silently vanished from the report, and the script
exited 0 -- the precise false clean this PR exists to prevent, reachable
without any corruption at all. It now takes the FIRST match. The path stays
adjacent on purpose: a looser "any name after metadata" matches
chart.templates[].name, which Helm emits immediately after metadata on every
healthy release, so the review`s suggested relaxation would have returned a
template path for every tenant. Over-strictness fails loudly and recoverably;
over-looseness deletes data quietly.

Newlines are now folded before matching, so a pretty-printed payload parses at
all rather than aborting, and whitespace around the punctuation is tolerated.
first_deployed got the same treatment -- it had the identical greedy, single-
line-only shape, and a spaced payload silently dropped the PV-vintage row from
the report.

The FATAL message names the path it read and the shape it expected, so a future
Helm format change is diagnosable instead of looking like real corruption.

Tests: three new payload shapes (spaced, pretty multi-line, and a values decoy)
each byte-compared against the same golden as the compact payload, so the shape
must make no difference to the report. Mutation-checked -- restoring last-match
extraction fails the decoy test on its own, restoring the single-line matcher
fails the pretty test.

The test fake answered any unmodelled kubectl invocation with exit 0 and empty
stdout, the fail-open shape this script was rewritten to reject, and enough to
let a newly added query pass the goldens unnoticed. Unmodelled calls now exit 97
naming the invocation. Verified inert first by instrumenting the fake: 88
invocations across the suite, none unmodelled. Also added the missing test for
the by-name PVC GET fatal path, whose FAIL mode existed with nothing behind it.

The runbook now tells the operator to read the exit code: a non-zero exit means
the table is incomplete and no step may be taken on it. That contract lived only
in the script header, while the runbook is what the operator follows.

29/29 tests green; sh -n clean.

Andrey Kolkov 8aeedde088 feat(backups): support PostgreSQL point-in-time recovery (PITR) (#3383)
## What this PR does

Makes PostgreSQL point-in-time recovery (PITR) a genuinely supported,
tested capability for the new `backups.cozystack.io` API. Fixes #2774.

Was **stacked on #3313** (`fix/3300-cnpg-barman-plugin`) for the
`recoveryTime` → CNPG `bootstrap.recovery.recoveryTarget.targetTime`
plumbing; #3313 has since merged and this branch is rebased on `main`.
This PR adds the reliability + verification layer #2774 asked for.

### Changes

- **Precise failure reason for an unreachable target.** The restore
deadline (`spec.options.restoreTimeoutSeconds`, default 30m) stays the
sole authority for "this restore is stuck" — the client waits the full
window either way. What changes is the *diagnosis*: once the deadline
has elapsed, if `recoveryTime` was set and the recovery Cluster never
went healthy, the CNPG driver reads the `full-recovery` pod logs and —
when several distinct attempts exited with PostgreSQL's `FATAL: recovery
ended before configured recovery target was reached` — fails the
RestoreJob with `RecoveryConverged=False` / `Ready=False` (reason
`RecoveryTargetUnreachable`) and an actionable message, instead of a
bare generic timeout. Timing is unchanged; only the reason/message
differ. (For a faster rejection, set a shorter `restoreTimeoutSeconds`.)
Design points:
- **We deliberately do NOT trip early off the FATAL.** A valid near-now
target emits that same FATAL transiently — repeatedly, for many
attempts, on a slow archiver — before it converges, so any earlier trip
would wrongly reject a recoverable restore (observed twice in CI). The
FATAL is used only to *explain* a failure the deadline has already
declared.
- **Health wins unconditionally** — the deadline/classification check
precedes the healthy check, but a recovery that converges within the
window reaches success and is never classified as failed (a live dev7
restore did exactly this).
- **Counting distinct FATAL-ing attempts** (not pod failures) tolerates
a one-off archive-lag miss on a near-now target and ignores transient
recovery-pod crashes (a node blip / brief API-server unreachability
never emits that FATAL).
- Adds the `pods/log` RBAC grant the log read needs (distinct
subresource from `pods`); a `Forbidden` is logged loudly and surfaced in
the failure message rather than silently disabling the classification.
- **e2e** (`examples/backups/postgres/run-all.sh`, wired into the
Chainsaw `postgres-2-backup-roundtrip` suite):
- Step 45 — write `before`, capture server timestamp (µs precision),
write `after`, restore to that timestamp, assert `before` present and
`after` absent.
- Step 46 — a `recoveryTime` an hour ahead must fail with reason
`RecoveryTargetUnreachable` once the deadline elapses (asserts the
*reason*, so it proves the classification fired, not just that a timeout
occurred).
- Chainsaw budget raised 25m → 40m to cover three sequential restores +
the post-deadline classification.
- **Docs + example**: uncommented `45-restorejob-pitr.yaml`; a
`docs/operations/backup-classes.md` PITR section (recoverable window,
discovering earliest/latest restorable time from the backup catalog
since `firstRecoverabilityPoint` is unreliable under the plugin,
archive-lag tolerance, idempotency under GitOps).

### Verification

- `go build` / `go vet` clean; unit tests pass
(`logIndicatesRecoveryTargetUnreachable`, `recoveryUnreachableFromLogs`,
`recoveryPodsToInspect`, nil-Clientset guard, a reconcile-level
success-path test asserting `Succeeded` + `RecoveryConverged=True`, and
— added per review —
`TestReconcileCNPGRestore_DeadlineClassifiesRecoveryTargetUnreachable`,
a reconcile-level test driving the deadline branch through all three
sub-paths: FATAL found → reason `RecoveryTargetUnreachable`, FATAL
absent → generic timeout, `Forbidden` log read → generic timeout +
missing-`pods/log`-RBAC note. It fails if the call-site reason is
reverted to the generic one).
- Reviewed via adversarial branch-review; fixes include a critical
missing-RBAC dead-on-arrival, a classification false-positive on
transient recovery-pod crashes, and a sub-second e2e flake.
- **dev7**: backup + WAL archiving + recovery convergence verified live
on the #3313 build. The load-bearing assumption of the classification —
CNPG **accumulates** failed `full-recovery` pods rather than reusing one
— was confirmed (observed 7 simultaneous failed recovery pods). A
fully-green live step-46 run was blocked by intermittent COSI
bucket-provisioning flakiness on dev7; the negative path is covered by
the CI Chainsaw e2e.

### Downstream repositories

Walked the trigger map in `docs/agents/contributing.md` against the
diff. The only user-facing surface is the new

```release-note
feat(backups): PostgreSQL RestoreJob now supports point-in-time recovery (PITR). Set spec.options.recoveryTime (RFC3339) to restore to an exact instant. A recoveryTime past the latest archived WAL still runs to the restore deadline (spec.options.restoreTimeoutSeconds, default 30m), but the failure is now reported with the precise reason RecoveryTargetUnreachable and an actionable message instead of a generic timeout; set a shorter restoreTimeoutSeconds for a faster rejection.
```

Andrey KolkovandClaude Opus 4.8 6a1e2d0d06 feat(backups): support PostgreSQL point-in-time recovery (PITR)
Makes RestoreJob.spec.options.recoveryTime a genuinely supported, tested
capability for the new backups.cozystack.io API (issue #2774). The
recoveryTime -> CNPG bootstrap.recovery.recoveryTarget.targetTime plumbing
already existed on the barman-cloud-plugin branch; this adds the reliability
and verification layer the issue asked for:

- Fail-fast for an unreachable target: when a RestoreJob has recoveryTime set
  and the recovery Cluster is not healthy, the driver reads the CNPG
  full-recovery pod logs and, once several distinct attempts have exited with
  PostgreSQL's "recovery ended before configured recovery target was reached"
  FATAL, fails the RestoreJob with conditions RecoveryConverged=False /
  Ready=False (reason RecoveryTargetUnreachable) instead of hanging to the
  restore deadline. Health is checked first, so a converged recovery always
  wins; counting distinct FATAL-ing attempts (not pod failures) tolerates a
  transient archive-lag miss on a near-now target and ignores transient
  recovery-pod crashes. Adds the pods/log RBAC grant the log read requires.

- e2e (examples/backups/postgres/run-all.sh, wired into the Chainsaw
  postgres-2-backup-roundtrip suite): step 45 writes a before marker, captures
  the server timestamp, writes an after marker, restores to that timestamp and
  asserts the before row survived and the after row did not; step 46 submits a
  recoveryTime an hour ahead and asserts it fails fast with reason
  RecoveryTargetUnreachable.

- Working, uncommented example (45-restorejob-pitr.yaml) and a docs section
  (docs/operations/backup-classes.md) covering the recoverable window, how to
  discover the earliest/latest restorable time from the backup catalog, the
  archive-lag tolerance, and idempotency under GitOps.

Andrey KolkovandClaude Fable 5 7d117679d4 docs(backups): document bucketName's two modes, cover isp-hosted in the wiring test
Branch-review on this PR: for provisionBucket: false the
backupstrategy-controller.bucketName helper returns
.Values.backupStorage.bucketName verbatim as the real S3 bucket name
and every strategy CR plus the Velero BSL bakes it in, so the
external-S3 section must require updating bucketName (the Secret's
bucketName key alone is not read by the strategies), and the knob
table must state the two-mode semantics instead of the COSI-only one.
Also route the external-S3 instruction through the platform component
override instead of naming raw chart values, and add the isp-hosted
variant case to the forwarding test (92 tests green).

Andrey KolkovandClaude Fable 5 1422f8b78a fix(platform): forward backupStorage overrides to the backupstrategy-controller Package (#3245)
The documented admin override for the cozy-default backup S3
coordinates (spec.components.backupstrategy-controller.values on the
cozystack.cozystack-platform Package) had no effect: that PackageSource
exposes only the platform component, so the operator silently ignored
the block, and nothing in the platform chart forwarded backupStorage to
the child Package.

Wire it the same way bundles/iaas.yaml forwards kubevirt / gpu-operator
values: a new top-level backupStorage value on the platform chart is
rendered into the emitted cozystack.backupstrategy-controller Package
CR as components.backupstrategy-controller.values.backupStorage, from
where the cozystack operator merges it into the
backupstrategy-controller HelmRelease over the chart defaults. When
backupStorage is unset the emitted Package is unchanged.

Update docs/operations/backup-classes.md to the working override path
(spec.components.platform.values.backupStorage) and call out the two
plausible-looking paths that do not work. Add a helm-unittest suite
covering the no-op default and the forwarding on isp-full and
isp-full-generic.

Fixes #3245

## What this PR does

Fixes #3300. Migrates CNPG Postgres backups off the deprecated native
`spec.backup.barmanObjectStore` (removed in CNPG 1.29; the
`barman-cloud-*` binaries it needs are absent from the `standard` image
variant keycloak-db pins, and the bare system-flavor tags apps/postgres
pins are deprecated upstream) onto the [CloudNativePG Barman Cloud
plugin](https://github.com/cloudnative-pg/plugin-barman-cloud), across
every Postgres backup surface: `apps/postgres`, `system/keycloak`, and
the `cozy-default-cnpg` BackupClass strategy driver. The chart renders
`spec.plugins` + a `barmancloud.cnpg.io/ObjectStore` CR; the
backup-controller driver SSA-applies an `ObjectStore` and patches
`spec.plugins`; `Backup`/`ScheduledBackup` use `method: plugin`. The
`postgres-operator` chart vendors and co-locates the
`plugin-barman-cloud` operator (with its cert-manager-issued mTLS) so
CNPG can discover it.

One platform-level change is required for the plugin to run and ships
with this PR (see the upgrade notes in
`docs/operations/backup-classes.md` and the release note below): the
CloudNativePG operator is bumped to 1.28.1 (also fixing an operator/CRD
version skew that broke all backups). The other prerequisite — the
LINSTOR scheduler admission webhook stripping
`initContainers[].restartPolicy` cluster-wide, which broke the plugin's
restartable sidecar — is already fixed on `main` (f4aef7305 re-vendors
`linstor-scheduler` to upstream chart 0.3.1 / extender v0.3.6, which
keeps the webhook and stops stripping unknown pod fields), so after the
rebase this PR no longer touches `linstor-scheduler`; just do not hold
that package back on an older version when rolling out the plugin.

Supersedes #3306 (the keycloak `system`-image workaround): keycloak-db
now backs up via the plugin on the `standard` image, so that stopgap is
no longer needed.

fix(backups): migrate CNPG Postgres backups to the CloudNativePG Barman Cloud plugin

Postgres backups (apps/postgres, system/keycloak, and the cozy-default-cnpg BackupClass strategy) now use the CloudNativePG Barman Cloud plugin (spec.plugins + a barmancloud.cnpg.io/ObjectStore, method: plugin) instead of the deprecated native spec.backup.barmanObjectStore (removed in CNPG 1.29; the barman-cloud-* binaries it needs are absent from the standard image variant keycloak-db pins, and the bare system-flavor tags apps/postgres pins are deprecated upstream). The barman-cloud plugin operator is installed alongside the CNPG operator.

One platform-level change rides along and requires operator attention on upgrade:
- The CloudNativePG operator is bumped to 1.28.1 (fleet-wide minor upgrade); this also fixes an operator-newer-than-its-CRDs skew that made the operator report "instance manager was restarted during backup" and fail every backup. The vendored chart ships the CNPG CRDs as ordinary release manifests (crds.create), so helm upgrade updates them with the operator; the skew came from the image.tag pin outrunning the chart's CRDs, which this PR removes.
- The plugin's restartable sidecar requires the linstor-scheduler admission webhook that no longer strips initContainers[].restartPolicy (upstream chart 0.3.1 / extender v0.3.6, shipped separately on main); do not hold the linstor-scheduler package back on an older version when rolling out the plugin.
```

Myasnikov Daniil b4f98af940 docs(seaweedfs): fail closed in the rename runbook's reclaim-policy handling
The 1.5.x->1.6 rename recovery runbook deletes each volume PVC after
switching its PV to Retain, but the switch was never gated on success.
With no `set -e`, a failed `kubectl patch ... Retain` left the PV at
Delete and the following `delete pvc` took the data with the claim.

Gate the delete on both the annotation record and the Retain patch
succeeding, aborting the re-bind loop otherwise, so no PVC is deleted
while its PV is unprotected. In the Step 5 restore loop, chain the
annotation removal after the restore patch with `&&` so a failed patch
keeps the saved policy for a retry.

Address review feedback from coderabbitai on
docs/operations/seaweedfs-431-rename-recovery.md.

Myasnikov Daniil 95fcc76902 docs(seaweedfs): scope the rename runbook to the supported instance name
The tenant module is the supported way to run SeaweedFS and it hardcodes the
instance name: packages/apps/tenant/templates/seaweedfs.yaml creates the
HelmRelease as `seaweedfs`, and a tenant can only enable or disable it. Every
shell selector in this runbook assumes that name, so say so up front, and route
instances created directly against the API under other names to escalation
instead of through loops whose name filters provably cannot see truncated
claims. The ~40-char zone/pool key limit of the guard's reconstruction is
called out as an accepted limit for default-named instances too.

Two content fixes ride along, both for findings the final review pass raised:

- The emptiness check told the operator to kubectl exec the candidate's own
  volume pod — which for a D-wedged duplicate can never start; that is the
  definition of the class, so the check was unexecutable exactly where it
  matters most and every D-wedged tenant funneled to escalation. Mount each
  bound candidate claim read-only in a scratch pod instead (a Pending claim
  has no PV and is empty by construction). The weed shell cross-check stays
  on the authoritative master, which is running.

- Step 1's description of the audit now matches the audit itself: direction
  is decided by the relative strictly-newer PV rule (the same precondition
  Step 2a enforces), and an interrupted re-bind reads as overlapping vintages
  with no candidate — not by a clock window anchored on first_deployed.

Myasnikov Daniil 601f164c5f fix(seaweedfs): stop the naming guard guessing which volume generation holds the data
The guard told a class-S tenant from a D tenant by comparing PVC creationTimestamps,
on the premise that "PVCs are never recreated in place, so the older generation is
where the data was born". The premise is false, and this runbook is the counter-
example: Step 2's re-bind DELETES each release-named claim and recreates it under
the chart name against the same PV.

So a tenant interrupted part-way through Step 2 — after volume-0, before volume-1 —
has data1-seaweedfs-volume-0 created SECONDS ago holding real data, beside
data1-seaweedfs-system-volume-1 with the original timestamp also holding real data.
That is the exact inversion of the rule. Reproduced against the old template:

  keeps its data on the release-named volume PVCs (created 2026-06-20T07:01:59Z,
  OLDER than the chart-named data1-seaweedfs-volume-* claims created
  2026-07-17T09:30:00Z) ... Remove the empty chart-named set ... (Step 2a, then Step 2)

Step 2a then runs `grep -E '^data1-seaweedfs-volume' | xargs kubectl delete pvc` —
deleting the claim Step 2 had just re-bound — and Step 2 had already restored the
PV's original reclaim policy, so on any Delete-policy StorageClass the volume and
the bytes go with it. The guard's own recovery path was a data-loss instruction.

Two more holes in the same classifier:

- The S-damaged branch was gated on $systemPVC, which requires the PVC name to
  contain "seaweedfs". seaweedfs.componentName truncates the fullname to 56 chars
  before appending -volume, so an instance name >= ~40 chars drops the chart name
  off the PVC name — the very case fullname_override_named_test.yaml exists for.
  Probed with `archive-of-quarterly-financial-statements-x1`: damaged + renamed set
  Ready fell through to the D-split branch ("is running two live SeaweedFS sets ...
  Stop the split"), sending the operator to quiesce the set holding ALL the data —
  the exact misclassification the parent commit exists to remove. Damaged + not
  Ready fired no branch at all and rendered through unguarded.
- readyReplicas == 0 was read as proof the duplicate never served. It is a
  snapshot: a duplicate that crashed, was scaled down, or lost readiness AFTER
  serving writes reads identically, and adoption strands whatever it wrote.

There is no sound signal here. Claim timestamps are mutable, StatefulSets are
recreated by the adoption hook, and liveness is a snapshot — nothing durable in the
object graph distinguishes "empty set a bad upgrade created" from "the data,
mid-re-bind". Rather than add a fourth heuristic, the guard now decides only what
is decidable:

  legacy generation only (or nothing) -> render; adoption is correct
  release-named generation only       -> refuse, class S (Step 2)
  BOTH generations                    -> refuse; an operator classifies

Both generation flags now OR the PVC and StatefulSet evidence, so the truncated
long-name tenant is seen via its label-matched StatefulSet.

The cost is bounded and lands only where it should. A duplicate exists only on a
tenant that passed through the broken 4.31 rename in 1.5.x — already damaged,
already needing an operator. A 1.4.x tenant upgrading straight to 1.6 never
renames, so it has one generation and is untouched. Confirmed on the stand:
tenant-l (1.4.5-era, never upgraded) is legacy-only and dry-runs clean; the four
both-generation tenants all already need an operator. What is lost is D-wedged
auto-adoption, which was resting on the readyReplicas assumption above.

Classification moves to the runbook, where a human has signals a template does not:
Step 1 now reads the ages of the PVs (durable — they survive the re-bind) via
.spec.volumeName instead of the claims, reports MIXED instead of picking, and walks
the operator through interrupted-Step-2 first, then strict age separation, then
verifying emptiness directly, then escalating rather than guessing. Step 2 stashes
the PV's original reclaim policy ON THE PV and leaves it Retain until Step 5
verifies the tenant, so a mis-step during recovery is survivable. Step 2a grows a
precondition that refuses unless every chart-named claim is bound to a strictly
newer PV.

Tests: 7 of 14 in the enforcing suite fail against the old template, including the
interrupted-Step-2 tenant and both truncated-long-name cases. hack/seaweedfs-guard-
parity.bats pins the two copies (system/ enforcing, extra/ sibling) against silent
drift — they cannot share a library, neither chart depends on cozy-lib, and "keep
these in sync" as a comment is the failure class this whole branch is about; it
also pins that creationTimestamp and readyReplicas never come back.

`make test` in both charts now runs helm template --is-upgrade and greps for the
refusal. The fail-closed canary — the headline safety property — had ZERO automated
coverage: guard_fail_closed_test.yaml passes with AND without the fix, because
helm-unittest 1.0.3 ignores release.isUpgrade. Verified the new target fails when
the canary is removed.

Review round 3 — the refusal was right; the justification was false and the
procedure that replaced the chart's judgement was broken on both axes.

THE COMMENT WAS WRONG. It said "nothing durable in the object graph distinguishes
the empty generation from the data mid-re-bind". A durable signal does exist, and
the reviewers were right to call that out: the Helm release history. Verified on
the stand — sh.helm.release.v1.<name>-system.v1 records the scheme the tenant was
BORN under (tenant-root/l/dsplit/named rev 1 render seaweedfs-master => pre-4.31;
tenant-fresh renders seaweedfs-system-master => 1.5.x), and info.first_deployed is
on every retained revision, so anchoring PV creationTimestamps against it survives
history pruning and the Step 2 re-bind (tenant-root: chart-named +10s vs
release-named +2084s; tenant-fresh: +5225s vs +6s).

BUT IT DOES NOT UNLOCK AUTO-ADOPTION, and that is the substantive disagreement
with the round-3 direction. Birth order answers "which generation is ORIGINAL".
Adoption needs "is the OTHER one EMPTY". Those come apart exactly where it
matters: D-wedged (duplicate never scheduled, safe to adopt) and D-split
(duplicate served writes, adopting strands them) are BOTH born pre-4.31 and are
therefore identical on every durable signal. Verified: tenant-root and
tenant-dsplit have the same rev-1 scheme and the same first_deployed deltas, yet
one duplicate served and the other did not. The only thing that ever separated
them was readyReplicas, which is a snapshot and not evidence. So the render keeps
refusing on presence, and the comment now says why — naming the signal, so nobody
re-derives the broken one.

The signal IS used where it belongs, in the audit.

- naming-guard.yaml / seaweedfs.yaml: match the release-named generation by
  RECONSTRUCTING the name 4.31 gives this release's volume component
  (templates/_naming.tpl, replaying seaweedfs.fullname + componentName), tested
  FIRST because the prefixes nest. Fixes a blocker: an instance legitimately named
  `seaweedfs-volume` renders seaweedfs-volume-system-volume and
  data1-seaweedfs-volume-system-volume-0, which BOTH satisfy the chart-named
  prefixes — a prefix-only guard read its live storage as legacy and would render
  onto the empty chart-named claims, stranding the real generation. The parity
  bats passed straight through it, because parity pins sameness, not correctness.
  Reconstruction also removes the name-match blind spot at source: a truncated long
  instance name now matches by PVC, not only by StatefulSet.

- hack/seaweedfs-naming-audit.sh + .bats: the classifier is a tested script now.
  Two revisions of it shipped as an untested snippet inside the runbook and both
  were wrong in ways that routed a live tenant into the step that strands its data:
  a selector `^data1-(.*seaweedfs.*)-volume` that also matched the chart-named
  claims, so the release-named range spanned BOTH generations, every tenant read as
  "overlapping / mid-rebind", and a genuine S-damaged tenant was routed AWAY from
  Step 2a into Step 2 — which deletes its data claim, fails to recreate it, then
  deletes its StatefulSets; and a `grep seaweedfs` name match that reported
  "L — nothing to do" for a long-named tenant the chart refuses. Both are covered.
  The audit reports L/S/MIXED matching the guard, names the original generation
  from both durable signals, detects MID-REBIND (both generations at
  first_deployed), and states plainly that "original" is not "empty" and that
  emptiness must be established from the duplicate's volume files before deleting.
  A bats case renders _naming.tpl through helm and compares it to the script's
  reconstruction, so the two implementations cannot drift.

- Runbook: Step 1 calls the script. Steps 3/4 were circular — Step 3 ended in an
  upgrade the presence-gated guard refuses, and Step 4 told the operator to clear
  duplicates AFTER an upgrade that cannot run until they are gone. Step 3 now
  removes the duplicate BEFORE the upgrade and re-runs the audit to prove it; Step 4
  starts from "every tenant reads L or S". D-wedged no longer claims to need
  nothing. Step 3's "enumerate fids that resolve only on the duplicate" was not an
  executable procedure and is now an explicit escalation: two masters allocate
  volume IDs from independent sequences into one shared seaweedfs-db, so there is
  no supported tool that reconciles two volume-ID spaces against one metadata
  store. Step 2's re-bind restores the cleanup hook's labels on the recreated
  claims, without which a recovered tenant leaks its volumes on a later delete.

Fixture corrected: data1-...-x1-system-volume-0 is not a name the chart renders;
componentName gives ...-x1-system-seaw-volume-0.

Myasnikov Daniil 47e24f01d1 fix(platform): hand seaweedfs-db over for every instance name, not just the default
Migration 43 performs the v1.5.0 db-split hand-over: it re-owns Cluster/seaweedfs-db
from <name>-system to the new <name>-db release and stamps
helm.sh/resource-policy: keep, so the <name>-system upgrade — whose post-split
chart no longer renders the Cluster — does not prune it as a removed resource.

It compared the owning release name against the literal "seaweedfs-system".
SeaweedFS is a user-creatable kind, so an instance named `foo` is owned by
`foo-system` and was silently skipped: no re-own, no keep. The <name>-system
upgrade then deleted the Cluster, CNPG took its PVC with it, and the filer
metadata — the index for every object in that tenant's S3 — was destroyed. Data
loss, not an outage: the volume PVCs still hold the bytes, nothing can find them.

Verified live on the upgrade stand, which is a natural control group. All five
tenants sit in the SAME failed-upgrade loop (<name>-system last-deployed is
rev 1, a pre-split revision whose manifest still contains the Cluster, so every
retry recomputes the same deletion):

  tenant-root/dsplit/l   instance `seaweedfs`  owner=seaweedfs-db  keep   Cluster alive
  tenant-named           instance `foo`        no Cluster at all          Cluster GONE

The only difference is that migration 43 fired for the default-named instances
and skipped `foo`. That also answers whether `keep` is sufficient: three tenants
survive the identical prune loop with it.

Correction to the reported mechanism: this is the 1.4->1.5 db split (PR #2601,
v1.5.0), not a 1.5->1.6 change — v1.5.3 and main are identical on every
db-split file. And the split does protect the object; it just only protected the
instances someone happened to name `seaweedfs`.

- lib/seaweedfs-db-adopt.sh: shared hand-over matching the `-system` SUFFIX, so
  `foo-system` -> `foo-db` exactly as `seaweedfs-system` -> `seaweedfs-db`.
  Idempotent, and refuses a release named literally `-system` rather than
  annotating an owner of `-db` that no release would claim.
- Migration 43 sources it: covers clusters upgrading from before 43 (1.4.x).
- Migration 53 (new) re-runs it: migrations never re-run, so any cluster already
  at >= 44 ran the hardcoded version and is still exposed. As a pre-upgrade hook
  it lands before <name>-system re-renders, closing the window on THIS upgrade.
  This is the one that matters for 1.5.x -> 1.6.
- targetVersion 53 -> 54.

Tests fail on unfixed code: the non-default-name case produces no ANNOTATE at
all against the hardcoded 43, while the default-name case passes — which is
precisely the bug's shape. They drive the real migration scripts against a fake
kubectl, following hack/migration-50-etcd-adopt.bats.

LIMIT, stated plainly: a Cluster that is already deleted cannot be recovered by
either migration — there is nothing left to re-annotate and the PVC went with
it. Such a tenant needs seaweedfs-db restored from a backup. Runbook Step 0 adds
the ownership audit that distinguishes at-risk from already-lost, and records
that <name>-db can report Ready while its Cluster is gone (it rendered fine; a
later <name>-system prune removed it and Flux has not re-checked) — so the
audit trusts `kubectl get cluster`, not the HelmRelease status.

Review round 2 — two ways this still lost the database:

- OWNERSHIP IS NOT SAFETY. The helper skipped any Cluster already owned by
  <name>-db, treating ownership as proof the hand-over was done. It is not: where
  the hand-over was skipped, <name>-system prunes the Cluster and <name>-db
  RECREATES it under its own ownership with NO keep, while <name>-system's prune
  baseline still lists it — so the next reconcile deletes it again. That is the
  observed delete/recreate loop, and the skip walked straight past it. Verified on
  the stand: tenant-l and tenant-root are seaweedfs-db-owned AND their
  <name>-system deployed revision (rev 1) still contains the Cluster, so only keep
  saves them; tenant-fresh is seaweedfs-db-owned without keep but was installed
  after the split, so its baseline never had one. Telling those apart needs the
  release's deployed manifest, which this script cannot read cheaply or reliably.
  The costs are asymmetric — a needless keep leaves an orphan on delete (now
  reclaimed by the cleanup hook), a missing one loses the database — so keep is
  stamped on every Cluster owned by either side of the split.

- FAIL OPEN, THEN STAMP. `set -euo pipefail` does not abort on a failing command
  substitution in a `for` word-list: the loop ran zero times, the script continued,
  and stamp_cozystack_version ran anyway. Migrations never re-run, so one throttle,
  RBAC hiccup, or not-yet-established CNPG apiservice behind the pre-upgrade hook
  permanently left every at-risk tenant exposed with no later migration to catch
  them. Reproduced: against the old helper a failing fleet scan still logged
  STAMP 54. Now every kubectl failure is fatal EXCEPT the two that genuinely mean
  "nothing to do" — the CNPG resource type not being served (the fail-open that IS
  load-bearing: a cluster without CNPG must still upgrade) and a Cluster vanishing
  between scan and read. An unreadable annotation is no longer indistinguishable
  from an absent one, and the unowned case now warns instead of passing silently.

- ORPHAN ON DELETE. `keep` is permanent (removal deferred to the 1.7 batch
  migrations) and also survives the <name>-db release's own uninstall, so
  `kubectl delete seaweedfs <name>` left the CNPG Cluster, its Postgres pods and
  its PVCs behind — the cleanup hook selects
  app.kubernetes.io/instance=<name>-system, which the db PVCs
  (cnpg.io/cluster=seaweedfs-db) do not carry. Migration 53 widened that from
  pre-1.5 default-named tenants to every instance name, so the hook now deletes
  the Cluster explicitly; its PVCs carry ownerReferences to it and follow.

- Tests assert the stamped VERSION (44 / 54), not a bare "STAMP": a wrong number
  would loop run-migrations.sh forever and the old assertion could not tell.

Review round 3 — the reclaim introduced a data-loss path of its own:

- DELETING ONE APP DELETED ANOTHER APP'S DATABASE. The db chart hardcodes the
  Cluster name `seaweedfs-db` for every instance, and the reclaim was scoped by
  that name in the namespace rather than by what the release owns.
  templates/seaweedfs-db.yaml gates the <name>-db HelmRelease on
  `topology != "Client"`; the cleanup hook had no such gate. Verified by render:
  `helm template s3-remote . --set topology=Client` emits ZERO s3-remote-db
  HelmReleases yet still emitted the Role granting delete on clusters/seaweedfs-db
  AND `kubectl delete cluster.postgresql.cnpg.io -n tenant-root seaweedfs-db`. So
  in a namespace running a server instance plus a Client, deleting the CLIENT
  destroyed the SERVER's filer metadata — CNPG takes the PVC via ownerReferences —
  for an app the operator never touched. Reachable the same way via a second Simple
  instance, whose <name>-db loses Helm's ownership check but which still installs
  and still carries the hook. main's hook was instance-scoped; this was new, and
  mine.
  Now gated exactly as seaweedfs-db.yaml is, and the Job re-checks
  meta.helm.sh/release-name == <release>-db at run time before deleting. The gate
  stops the permission being granted where it can never be legitimate; the runtime
  check stops the delete where it can.

- `|| echo` turned any API/authz/admission failure into exit zero, so backoffLimit
  never retried and hook-delete-policy removed the only cleanup Job while the
  keep-protected Cluster stayed orphaned. A failed reclaim now fails the Job.

- TEST SHELL. The migrations run under /bin/sh = busybox ash (the image is FROM
  alpine, run-migrations.sh is #!/bin/sh), but the tests drove them with bash — so
  the fail-closed guarantees were asserted in a shell that never runs them, which
  matters more than usual given the bug they cover was a fail-open. The scripts are
  now invoked via `sh` and the fake kubectl is POSIX sh. Verified directly against
  the production base image (busybox 1.37.0 / alpine:3.24): `set -o pipefail` is
  supported, every script passes `ash -n`, and the failing-fleet-scan path exits
  non-zero without stamping under real ash. The recipe is in the bats header.

Myasnikov Daniil ae93356ed1 fix(seaweedfs): name cluster-scoped RBAC per namespace, not after the pinned fullname
ClusterRoles and ClusterRoleBindings are cluster-scoped: one object per name,
cluster-wide. This chart installs once per tenant, so every cluster-scoped name
it renders must be unique per install. Four of them were not.

Upstream 4.31 switched them from global.serviceAccountName to seaweedfs.fullname.
That is fatal in combination with the #3282 pin: fullnameOverride: seaweedfs is
what adopts the running NAMESPACED workloads across the rename, so fullname is by
construction the SAME string in every tenant. Every SeaweedFS instance in the
fleet therefore renders seaweedfs-objectstorage-provisioner, seaweedfs-rw-cr and
their bindings — one object, five claimants.

NOT a #3282 regression. Rendering v1.4.5, v1.5.3 and main for the same tenants:

  v1.4.5  tenant-root-seaweedfs-*      tenant-named-seaweedfs-*     unique
  v1.5.3  seaweedfs-system-*           foo-system-seaweedfs-*       COLLIDES
          (identical for every default-named instance; a non-default
           instance name was the only thing that escaped)
  main    seaweedfs-*                  seaweedfs-*                  COLLIDES
          (nothing escapes: the pin removes the last distinguishing input)

So the collision shipped in 1.5.0 with the 4.31 bump; #3282 widens it from
"every default-named instance" to "every instance". Observed live on the upgrade
stand: one ClusterRole/seaweedfs-objectstorage-provisioner annotated to a single
owning tenant, four other tenants' COSI provisioners left with no RBAC, and
tenant-dsplit's helm history recording
  Upgrade failed: original object ClusterRole "seaweedfs-objectstorage-provisioner" not found

The binding is the sharp end: its subject names a ServiceAccount in the release
namespace, so the single live ClusterRoleBinding grants cluster-wide secrets RBAC
to whichever tenant reconciled last, and silently revokes it from the rest.

Fix: put the four names back on global.seaweedfs.serviceAccountName, which
extra/seaweedfs already sets to <namespace>-seaweedfs and which
cosi-provisioner-sa-name.patch already uses for the ServiceAccount and the
binding's subject — the cluster-scoped names were simply left behind. Three of
the four come out byte-identical to pre-4.31, so a 1.4.x tenant adopts them in
place; the fourth (rw-crb) replaces upstream's username-shaped
system:serviceaccount:<sa>:default and is pruned from the release's own manifest.
The namespaced pin is untouched: workloads still render seaweedfs-master/-filer/
-volume, so #3282's adoption is intact.

Uniqueness now rests on a value, so assert it rather than trust it:
templates/cluster-scoped-rbac-guard.yaml refuses to render when the name would
not carry the release namespace. It sits behind the same namespace canary as the
naming guard, because system/seaweedfs's own values.yaml ships a placeholder that
only extra/seaweedfs overrides — a client-side render must not trip on it.

Tests fail on unfixed code: cluster_scoped_names_test asserts two tenants get two
names, and unpatched both render seaweedfs-objectstorage-provisioner (5 failed,
0 passed). They test the vendored chart templates directly, which is where the
rename happens.

The guard includes seaweedfs.compat before reading. extra/seaweedfs sets the OLD
flat key global.serviceAccountName, and the shim is what folds it into the
canonical global.seaweedfs.serviceAccountName; without it the guard compares
against this chart's placeholder default and refuses every real upgrade. Caught
by helm upgrade --dry-run=server against the stand, not by unit tests — the
mocks never carry the flat key.

Verified live with --dry-run=server on the stand: tenant-l (installed pre-4.31,
never upgraded) already owns tenant-l-seaweedfs-objectstorage-provisioner and
tenant-l-seaweedfs-rw-cr, and the fixed chart renders exactly those — adopted in
place, no ownership error. tenant-root renders tenant-root-seaweedfs-* and also
dry-runs clean. Leftovers on the release-based names that a 1.5.x tenant passed
through are inert once every tenant is upgraded (no release renders them any
more) but are not always pruned, since more than one release claimed them; the
runbook adds the sweep.

Review round 2:
- The uniqueness guard used `contains .Release.Namespace $sa`, a substring test
  that accepts namespace `tenant-a` for service account `tenant-ab-seaweedfs` —
  a different namespace's. Anchored to hasPrefix "<namespace>-". It still asserts
  the VALUE the names are built from, not the rendered names, so it cannot catch
  the chart being reverted to name them after the pinned fullname;
  cluster_scoped_names_test.yaml covers that axis and is what actually bites.
- Added the case that would have caught the compat bug: every test set the
  CANONICAL global.seaweedfs.serviceAccountName, while production sets the OLD
  FLAT global.serviceAccountName that only seaweedfs.compat folds in. Deleting
  the include left the suite passing 5/5 while every real upgrade refused. The
  new case sets the flat key; with the include removed it now fails with the
  production error.
- Runbook sweep missed the fourth pre-4.31 name: 4.31 renamed the master-rw
  binding from upstream's username-shaped system:serviceaccount:<sa>:default to
  <sa>-rw-crb, and the old one carries neither suffix nor a tenant prefix, so the
  grep could not see it (live on the stand as
  system:serviceaccount:tenant-l-seaweedfs:default). Also documents the rolling-
  upgrade window: Helm prunes by name without checking ownership, so the first
  tenant onto the fixed chart deletes shared objects a not-yet-upgraded tenant is
  still bound through — COSI provisioning 403s until they reconcile, S3 traffic
  unaffected.

Review round 3:
- hasPrefix "<namespace>-" was still too loose. It accepts `tenant-a-b-seaweedfs`
  for namespace `tenant-a` — which is ALSO the natural value for namespace
  `tenant-a-b`, so two namespaces would accept one string and collide on the very
  object this guard exists to keep unique. extra/seaweedfs sets exactly
  `<namespace>-seaweedfs`, so assert equality with it and nothing looser.

Myasnikov Daniil 8499b5f4a1 fix(seaweedfs): move the naming-migration guard into the render that actually renames
The class-S guard from #3282 lives in extra/seaweedfs, but that render is not
in the path of a platform upgrade: the <name>-system HelmRelease pulls
system/seaweedfs from a platform-managed ExternalArtifact, so bumping the
platform upgrades the release directly from the new artifact and applies
fullnameOverride: seaweedfs without extra/seaweedfs ever re-rendering. On a
tenant installed fresh on 1.5.x that stood up an empty chart-named set beside
the live release-named data, deleted the renamed s3 Service, and left S3
readable only because the empty set's pods cannot start.

Worse, the damage flips the guard's own classification: creating the
chart-named artifacts makes $legacyData true, so the guard then reports
D-split and sends the operator to runbook Step 3 — which quiesces the renamed
set, i.e. the one holding ALL the data.

- Add the ENFORCING guard to system/seaweedfs (templates/naming-guard.yaml):
  the only render guaranteed to sit between a platform upgrade and the
  tenant's workloads. It also refuses to render if the fullnameOverride pin
  is ever lifted.
- Tell S from D by PVC AGE when both generations exist: PVCs are never
  recreated in place (StatefulSets are, by the adoption hook), so the older
  volume-PVC generation is where the data was born. Renamed-older ⇒ class S
  (damaged variant, new Step 2a), never D-split.
- Fail closed: the release namespace is a lookup canary; an upgrade that
  cannot see the cluster refuses instead of classifying blind. Client-side
  installs (CI lint/unittest) still render — they never touch live data.
- Mirror the same classification in extra/seaweedfs so the operator-facing
  SeaweedFS application reports the correct class.
- Tests now model the ExternalArtifact upgrade path in the chart it actually
  runs through (the old ones mocked lookups only in extra/seaweedfs, which is
  why this shipped green), including the damaged-S tenant observed live.
- Runbook: add S-damaged audit classification (PVC age), Step 2a cleanup of
  the empty chart-named set, and the D-wedged anti-affinity stall workaround
  observed on 3-node clusters.

helm-unittest 1.0.3 ignores release.isUpgrade, so the canary refusal is
verified with 'helm template --is-upgrade' instead of a unit test.

After the rebase onto main this PR no longer touches linstor-scheduler:
main re-vendored it to upstream chart 0.3.1 / extender v0.3.6, which
keeps the admission webhook and stops stripping unknown pod fields
(including initContainers[].restartPolicy the barman sidecar needs). The
upgrade note claiming the webhook is removed and locality scheduling
becomes advisory is rewritten as a hold-back warning.

Also: afterwards -> afterward (American English, review nit).

myasnikovdaniil 4a00b502d7 fix(seaweedfs): adopt legacy workloads in place across the 4.31 rename (#3282)
## What this PR does

Fixes a v1.5.0 upgrade regression where a tenant ends up with **two**
SeaweedFS workload sets.

**Root cause.** v1.5.0 bumped the vendored SeaweedFS chart `4.0.405 →
4.31.0`. Upstream changed resource naming: before 4.31 the chart named
workloads after the **chart** (`seaweedfs-*`, ignoring the release
name), and 4.31 names them after the **release**. The data-plane release
is `<name>-system`, so every StatefulSet wanted to become
`seaweedfs-system-*`. StatefulSet names are immutable, so Helm could not
rename in place — it stood up a second, empty set beside the running one
while the data stayed on the original `data1-seaweedfs-volume-*` PVCs.
Where the node count let both sets run, they shared one `seaweedfs-s3`
Service (identical pod labels) and one `seaweedfs-db` filer metadata
database, so the empty set answered reads and the two master sets mixed
volume IDs from independent sequences into one metadata table.

**Fix.** Pin `fullnameOverride` in `system/seaweedfs` values so the
rendered names stop following the release name, which is the convention
already used by `cozy-proxy`, `flux-operator`, `grafana-operator`,
`linstor-scheduler` and `victoria-metrics-operator`. The names go back
to what every pre-1.5 cluster already runs, so the upgrade adopts the
running workloads **and their volumes** in place. No data migration, no
platform migration.

**The one case that cannot be adopted.** A tenant installed *fresh* on
1.5.x wrote its data under the renamed workloads, so its volumes are not
the chart-named ones. Pinning the chart name there would rename the
workloads *away* from that data and bring up an empty cluster beside it.
Helm cannot move data between PVCs, so `extra/seaweedfs` refuses to
render for such a tenant and points at the recovery runbook, which
re-binds the existing PVs onto the adopted PVC names (no copying — the
claim is renamed, the volume is not touched). The guard is fail-closed:
it fires only when renamed volumes are present and no adopted ones are.

Two naming subtleties the guard has to respect, both verified by
rendering the shipped 1.5 chart:

- Before 4.31 the chart ignored the release name, so an instance running
under a non-default name (`SeaweedFS` is a user-creatable kind) *also*
stored its data on `data1-seaweedfs-volume-*`. Such a tenant is adopted,
not blocked.
- On 4.31 the fullname helper appends the chart name when the release
name does not contain it, and the component helper truncates to 56
characters. A fresh 1.5.x instance named `archive` therefore wrote to
`data1-archive-system-seaweedfs-volume-*`, and a long name loses the
chart name from its tail entirely. The guard matches volumes by shape
and by the chart labels on the StatefulSet instead of reconstructing
those names, so both are caught.

**On the duplicate set.** Once the fix reconciles, the
`seaweedfs-system-*` StatefulSets and Deployments are no longer part of
the release and Helm removes them on its own. What it cannot remove —
PVCs it did not template, and cert-manager Secrets that carry no owner
reference — is inert, and the runbook clears it explicitly. A
pre-upgrade migration was considered and dropped: it would duplicate
what Helm already does, while its only unique action (deleting PVCs)
cannot distinguish "the duplicate never served" from "it served and is
currently down", and any transient delete failure under `set -e` would
fail the platform's pre-upgrade hook and block delivery of this very
fix.

## Testing

`helm unittest` — `system/seaweedfs` 21 tests, `extra/seaweedfs` 17
tests. The guard's `lookup` branches are covered by mocking the
Kubernetes provider (the pattern already used in `core/platform` and
`system/cozystack-api`): adopted-only, renamed-only, both sets, zoned
volumes, a non-default instance name, a truncated long name, and an
unrelated `data1-*-volume-*` PVC that must not trip the guard. The
s3-consumer suite now re-creates the name/fullname divergence
explicitly, so it keeps guarding that regression regardless of the
shipped default.

The remaining regression test for this class of bug is an upgrade E2E
(seed a pre-4.31 named set, upgrade, assert a single set with data
intact) — no fresh-install E2E or `helm template` can reproduce an
upgrade over pre-existing state. That belongs in the chainsaw upgrade
lane and is a follow-up.

### Screenshots

N/A — no UI changes.

### Release note

```release-note
fix(seaweedfs): adopt existing SeaweedFS workloads and volumes in place when upgrading past the 4.31 chart rename, instead of standing up a second, empty cluster beside them
```

Myasnikov DaniilandClaude Opus 4.8 7e34e87cd9 docs(backups): document derive-from-Secret S3 endpoint behavior
The `backupstrategy-controller.endpoint` helper changed how the S3 endpoint is
resolved (for a provisioned bucket it derives from the COSI system Secret and
forces https://, with `backupStorage.endpoint` demoted to a fallback), but
docs/operations/backup-classes.md still described the old single-verbatim-value
behavior and directly contradicted the code:
- the "Endpoint format per driver" intro said the templates adapt "the single
  backupStorage.endpoint value";
- it claimed drivers "pull from backupStorage.endpoint in chart values, not
  from the Secret" — now precisely backwards for provisioned buckets;
- the values-table `endpoint` row omitted the fallback/derive semantics.

Rewrite those to match the new helper + the values.yaml comment.

Aleksei SviridkinandMyasnikov Daniil 5dc363d398 docs(seaweedfs): add 4.31 rename audit & recovery runbook
Classify each tenant from its volume PVCs, re-bind the volumes of a tenant
installed fresh on 1.5.x so the adopted names pick them up, stop a split cluster
before upgrading it, and clear the leftovers the upgrade cannot remove itself.
The recovery steps select the renamed set by a precise filter and derive secret
names from the fullname helper, so they work for an instance running under a
non-default name and for pooled or zoned volumes.

Aleksei SviridkinandMatthieu ROBIN cca54d876a docs(operations): resource presets reference
Document the five instance-type series (t1/c1/s1/u1/m1) introduced
alongside the legacy preset deprecation, the per-size CPU and memory
matrix, and the 1:1 legacy-to-instance-type mapping table that powers
cozy-lib aliases, migration 39, and the operator-side deprecation
warning.

Single source of truth referenced from:
  - packages/library/cozy-lib/templates/_resourcepresets.tpl
  - packages/core/platform/images/migrations/migrations/39
  - pkg/apis/apps/presets/legacy.go

Includes an explicit callout that legacy `medium` (1 CPU / 1Gi) and
instance-type `*.medium` (2 CPU) are not the same — same word,
different resources.

Replace inline preset tables in packages/apps/postgres/README.md and
packages/apps/kafka/README.md with a short paragraph that names the
five series and points at the canonical doc, since the per-app
inline tables listed only the legacy seven and would drift further
as the canonical matrix evolves.
