Tenant workload releases currently require a platform PR whenever Wedding App or AS Coaching publishes a new version. This makes the platform a per-release approval gate even though these tenants already publish signed artifacts and run inside platform-owned namespace, identity, network, and policy boundaries.

This change makes both tenant OCI sources follow signed stable releases with semver: ">=1.0.0". It also extends the rendered-tree OCI guard so any first-party tenant /manifests source pinned by tag or digest fails CI; the platform's own source keeps its independent ref policy. Tenants can now release freely inside their existing capabilities, while requests for new access still require a platform boundary change.

The immediate rollout also consumes Wedding App v1.15.11, which expands its three CNPG PVCs from 1 GiB to 2 GiB and resolves devantler-tech/wedding-app#321.

Validation:

  • RED: the guard accepted signed tenant manifest sources pinned by tag and digest
  • GREEN: both pins are refused; signed semver tenant streams and the platform-source control pass
  • shellcheck scripts/guard-oci-repository-verify.sh scripts/tests/test-guard-oci-repository-verify.sh
  • bash scripts/tests/test-guard-oci-repository-verify.sh
  • production render diff contains only the two OCIRepository ref-selector changes
  • EKS CI authorization contract passes with every RBAC and ServiceAccount identity unchanged
  • ksail workload validate and ksail --config ksail.prod.yaml workload validate started locally; hosted CI remains authoritative for the remote Helm-render pass

Merged main (5eecbd43) to clear the DIRTY state. Taken over because the authoring lane is not
producing and the branch had no push in ~6h.

One conflict, in scripts/validate-eks-ci-role-policy/main.go. Both sides had independently
re-approved expectedRenderedSurfaceSHAmain for the metrics-server baseline security defaults,
this branch for the signed-release-stream switch — so the merged tree renders an aggregate neither
side carried
. Picking either side would have been wrong. Resolved onto main's accumulated lineage
and re-approved at the merged tree's own value.

3a96640859aaee7dccae1b90c4a338395fd21c3df8abbd949f103e3ea9f39baa (was 23c6e285… here,
1b17b642… on main).

Evidence (local kubectl v1.36.1 / Kustomize v5.8.1; CI's SHA256-verified v1.36.2 remains the
authority and fails closed if it disagrees):

  • Renderer agreementmain at 5eecbd43 passes on this host against the constant CI
    approved, so this toolchain reproduces CI's digest and the value below is not a local artifact.
  • Conservation, both directions — read off the check's own error set, which walks
    actual→expected and expected→actual separately: exactly one error class (this aggregate), with
    0 unapproved rendered <identity>, 0 missing rendered authorization resource, 0
    duplicate rendered. Membership is conserved both ways; no subject, grant, binding or
    ServiceAccount moved. The 34 unresolved Flux substitution notes are the usual companions of a
    mismatch, not a second finding. An OCIRepository ref selector is not a grant-bearing field.
  • Positive — with the new constant the package suite is green, gofmt clean.
  • Negative control — restoring the superseded value fails with exactly this fingerprint, so
    the baseline is not vacuous.

The branch's authored delta is unchanged and still confined to the two OCIRepository ref selectors.

📝 Walkthrough

Walkthrough

Tenant application OCIRepository resources now use semver: ">=1.0.0" instead of fixed tags. The repository guard extracts reference fields and rejects pinned tenant manifest sources while preserving the platform boundary policy. Tests cover tag pins, digest pins, exemptions, platform sources, and resolver behavior. Documentation defines the tenant release contract. The authorization-surface fingerprint and measurement notes were updated.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 38be3

Tenant OCI sources now follow signed stable SemVer releases rather than fixed references, with protection against tenant tag or digest pins. No concrete current-head merge-blocking risk remains.

The re-approval note used "superseded" for two different hashes: this branch's
pre-merge value in one place and main's in another, and the negative control
did not say which one it restored.

List all three values by merge state and name the exact hash the control
substitutes.

Merged main again (4a6ea11e) — #3689 landed its own re-approval of expectedRenderedSurfaceSHA
at 23:53Z, which dirtied this branch on the same line.

That cascade is structural, not a mistake. While two branches each re-approve this constant,
whichever merges first moves main and the other must re-render. Worth knowing for sequencing: these
two were never independent.

Re-approved at the new merged tree's own value
8eff48ffd204d8b7fd933b19ad43c4f67570de912ce1032c2f40ab4b0c098836 (pre-merge here 3a966408…,
pre-merge main 36049e7e…).

Evidence, same shape as before:

  • Conservation, both directions — exactly one error class (this aggregate), 0
    unapproved rendered <identity>, 0 missing rendered authorization resource, 0
    duplicate rendered. #3689's three added identities are now in the base and therefore on both
    sides of the comparison, which is why the both-directions claim holds here.
  • Renderer provenancemain passes on this host against the pre-merge MAIN value, so this
    toolchain reproduces CI's digest; CI's v1.36.2 remains the authority.
  • Positive — package suite green, gofmt clean.
  • Negative control — restoring 36049e7e… fails with exactly 8eff48ff…, so the baseline is not
    vacuous.

The branch's authored delta is unchanged: still only the two OCIRepository ref selectors.

Review state at the previous head (bd81a2a5), for the next run: all three lanes were tried and
each refused — CodeRabbit Review rate limited 23:53:00Z, Codex usage limit reached 23:54:00Z,
Bugbot check-run neutral/Error with usage limit reached 23:54:28Z. That head's only CodeRabbit
review object was a blen=0 reply container, not a review. This push supersedes all of it: the new
head needs its own review round.

@devantler Full review complete. I found no new findings.

The tenant OCIRepository selectors, the rendered-source guard, and the related test coverage are consistent with the signed stable-release policy. The platform source remains excluded from the tenant selector rule.

Readiness at 38be356d13d00325375b73ac08bf4ccc672a9184 — promoting. All three conditions hold at
this exact head.

1. Programmatically tested. 28 checks: 21 success, 7 skipped, 0 non-green. Crucially, the
consuming job actually ran rather than being path-gated out: ci.yaml registers
scripts/guard-oci-repository-verify.sh and its test in a change filter, both are in this diff, and
the step 🔐 Validate every devantler-tech OCIRepository verifies reports success in run
34292880359 — so the new guard was exercised by CI at this head, not merely shipped alongside it.
0/1 review threads unresolved (complete read: fetched 1 of 1). No review-body finding sections and no
Codex ## Review finding at this head.

2. Reviewed. CodeRabbit green at this head, corroborated four independent ways: the
auto-generated summary refreshed 00:46:53Z naming the full head sha; the command-invocation reply
00:46:56Z carrying a positive verdict and no refusal marker; the head status transitioning
Review in progress 00:42:45Z → Review completed 00:46:55Z; and that completion postdating the
two earlier Review rate limited refusals (00:12:31Z, 00:23:56Z), which are therefore spent.

3. Tried and evaluated as a user. The guard is the change's exercisable surface pre-merge, and it
was exercised in both directions: RED — the guard accepted signed tenant /manifests sources pinned
by tag and by digest; GREEN — both pins are refused while signed semver tenant streams pass and the
platform's own source passes as the control, so the new rule is neither vacuous nor over-broad. The
production render diff contains only the two OCIRepository ref-selector changes, and the EKS
authorization contract passes with every RBAC and ServiceAccount identity unchanged in both
directions — with a negative control (restoring the superseded constant fails with exactly this
fingerprint).

Post-merge, this is 📊 Verifying, not done. The selectors become live only when Flux reconciles
them, and the first resolution pulls Wedding App v1.15.11, which expands three CNPG PVCs from 1
GiB to 2 GiB. That storage expansion is the observable effect to confirm after the merge-group deploy
— it is the point of the rollout, not a side effect, and it resolves
devantler-tech/wedding-app#321.

Enqueuing: main here is merge-queue gated, and devantler is not --auto-eligible, so this goes in
with an explicit head pin and no --squash (the queue chooses the strategy).

Root cause

source-controller logged the same error on every retry through the window:

failed to verify the signature using provider 'cosign keyless': no matching attestations:
failed to verify certificate identity: no matching CertificateIdentity found, last error:
expected SAN value to match regex
  ".../publish-app\.yaml@(625b7c0cd5ad4a04f9eb7494298c6d0fa44521ef|4f4e07a3ebf3e1161756a292966e36c91a65ee04)$"
got
  ".../publish-app\.yaml@b089a1b041cb86af22cdc57de58a4d7d258dcc32"

Moving spec.ref from tag: 1.13.4 to semver: ">=1.0.0" makes Flux resolve the newest
matching release instead of 1.13.4. That newer release was signed by publish-workflow revision
b089a1b0, which is not in this consumer's allowed pair. Verification fails, the OCIRepository
never goes Ready, and the apps health check blocks for its full 30m timeout.

b089a1b0 is legitimate — a verified chore(main): release 13.1.1 (#988) commit, an ancestor of
devantler-tech/actions main, and already the recorded applied_signer_sha for the aws
consumer in scripts/publish-workflow-approved-revisions.tsv.

Why this is not a flake, and not a one-line fix

The five merge-group CI runs before this one all succeeded, and prod converged on its own once
main was restored — so the eviction is this change, not the base.

The deeper problem is structural. publish-workflow-approved-revisions.tsv derives each
consumer's allowed pair from the currently pinned tag's signer plus the current main pin:

ascoachingogvaner  publish-app  1.13.4  ...  applied_signer=625b7c0c  main_pin=4f4e07a3

That derivation is only well-defined while a tag is pinned. Once spec.ref says "newest matching
semver", there is no way to know in advance which revision signed the release Flux will pick, and
it changes every time a tenant publishes. So as written the PR defeats its own stated goal — a
tenant release signed by any revision outside the pinned pair still needs a platform PR — and the
failure mode is not a benign "stays on the old version": it blocks the apps Kustomization for 30m
and takes the prod deploy down with it.

wedding-app has the same shape (applied_signer=6ae5d87b, main_pin=883d891a), so it is likely
to fail the same way once it resolves past 1.15.10.

What this needs

A decision on the trust boundary, not a revision bump — adding b089a1b0 to one row would only
move the failure to the next tenant release. Roughly:

  1. accept the reviewed union of approved revisions for tenant streams (still bounded, still
    reviewed, but far fewer platform PRs); or
  2. constrain the identity by issuer + workflow path + repository and stop pinning the revision for
    tenant manifest sources specifically; or
  3. keep per-release pinning and drop the "advances without a platform PR" goal.

Whichever is chosen, the health-check behaviour deserves attention separately: an unverifiable
tenant source should fail fast rather than consume a 30m timeout inside the prod deploy.

No re-queue until this is resolved. Left as a draft so no lane re-enqueues it in the meantime.

Root cause of the merge-queue eviction — named, and still live at this head

This PR's merge_group run failed its 🚀 Deploy to Prod with apps HealthCheckFailed … 30m, and the cluster event named the resource:

timeout waiting for: [OCIRepository/ascoachingogvaner/ascoachingogvaner status: 'InProgress']

The head has not moved since. The evicted merge-group ran at 2026-09-09T01:07:37Z; this PR's newest commit 38be356d13 is dated 2026-09-08T23:56:50Z. So the content that failed is the content sitting here now — re-queueing would evict again and burn another ~40 min prod deploy.

Why cosign cannot verify what the new ref resolves to

The change swaps ref.tag: 1.13.4 for ref.semver: ">=1.0.0". Those select different artifacts, and the signer allow-list was built for the first one.

scripts/publish-workflow-approved-revisions.tsv encodes, per consumer, the signer of the applied tag plus the consumer's current main pin:

ascoachingogvaner  publish-app  1.13.4  …  625b7c0cd5ad4a04f9eb7494298c6d0fa44521ef  4f4e07a3ebf3e1161756a292966e36c91a65ee04  2026-09-05

write-publish-workflow-matchers.sh renders exactly that pair, which is what the manifest now carries:

…/publish-app\.yaml@(625b7c0cd5ad4a04f9eb7494298c6d0fa44521ef|4f4e07a3ebf3e1161756a292966e36c91a65ee04)$

But >=1.0.0 resolves to the newest release, which is v1.13.5 (2026-08-24), not 1.13.4. And v1.13.5 was signed by a third revision — its cd.yaml at that tag pins:

uses: devantler-tech/actions/.github/workflows/publish-app.yaml@b089a1b041cb86af22cdc57de58a4d7d258dcc32  # v13.1.1

b089a1b0… is in neither alternative, so matchOIDCIdentity never matches, the source never goes Ready, and the apps health check consumes its full 30 m inside the prod deploy.

wedding-app passes by coincidence, not by construction

Its newest release v1.15.11 happens to be signed by 883d891a…, which is already its main_pin_sha. That is luck — it bumped its publish-app pin before cutting that release. Read it as a second instance of the same latent defect, not as evidence the model holds.

The model itself, not just this row

The TSV's two columns are "signer of the pinned tag" and "current main pin". Under a semver range there is a third relevant revision — the signer of whatever the range resolves to at reconcile time — and nothing tracks it. Patching the ascoachingogvaner row to 1.13.5 / b089a1b0… would go green today and reintroduce the same 30-minute prod outage the next time a tenant cuts a release signed by a revision the platform has not yet approved.

That is in direct tension with this PR's own stated goal, quoted from guard-oci-repository-verify.sh:

A tenant release must not require a platform PR merely to advance a tag or digest

As written, a tenant release still requires a platform PR whenever its signer changes — and until that PR lands, the tenant is not merely stale, it is failing.

Why every check was green over a prod-breaking change

report-publish-workflow-signing-revisions.sh answers precisely the question that would have caught this — "is the revision that signed what is deployed the same one this consumer pins today?" — but it is a report. Nothing fails CI on the answer, so the gap was invisible at merge time.

Status

Leaving this as a draft, parked on the named blocker above rather than patching the row to make it merge, because the row patch would re-arm the outage. I have not pushed to this branch. Design gap filed separately; linking it here once open.

Evidence gathered read-only against main, this head, the two tenant repos at their release tags, and this PR's own generator inputs — no cluster mutation.
