Probed the two operator-facing claims in the Builder's new commits (cbeceea, d5dc547). No inbox, no gate.
A-redfix-2 (LOW-MED) — "The wedge does not self-heal ... no code path redeploys it. Recovery is manual."
Conclusion right, mechanism wrong. abra.undeploy() does not remove the app .env, so the next reconcile()
sees current_version resolvable + is_deployed False and takes the fresh-deploy branch
(warm_reconcile.py:471-479), which redeploys and NEVER calls warmsnap -- the guard is unreachable there.
What actually blocks self-healing is the lack of a re-trigger: warm-keycloak.service is Type=oneshot with
no timer and no Restart=. So it heals on the next reboot / nixos-rebuild switch, then RE-WEDGES on the next
due upgrade because the foreign snapshot/meta.json is still in the slot. The failure therefore presents as
an intermittent flake, and the correct remediation is removing the foreign snapshot/, not redeploying
keycloak. Asked the Builder to correct two sentences; the precondition itself is unchanged and still right.
A-redfix-3 (INFO) — "main.go present in both clones => written outside git". Evidence void: /srv/cc-ci is a
SYMLINK to /srv/cc-ci-orch, so both paths are the same inode (2049:3254604, links=1). One file, one clone.
Risk bounded: 281-byte hello-world net/http listener, no go.mod, go not installed, nothing on :8080, in no
commit, unreferenced, inert. Concur with leaving it in place.
No VETO. DONE stands, M1+M2 PASS stand, merge target b5f2b10 unchanged. B-redfix-8 unchanged.

Builder asked me to confirm or refute that the _assert_slot_not_foreign x B-redfix-5 composition reaches
the UPGRADE path, not only the rollback path I named. Re-derived cold from source at b5f2b10; confirmed.
- snapshot() calls the guard FIRST (warmsnap.py:158, before _assert_undeployed) -> raises before docker.
- warm_reconcile.py:511-514 (undeploy -> wait_undeployed -> snapshot) is OUTSIDE the try/except at :520-525,
which wraps only deploy_version + wait_healthy. Neither abra.undeploy site (:512, :534) is covered.
- No enclosing try in reconcile(); sole caller main():556 does not catch -> SystemExit, no redeploy. The
app stays undeployed.
- Site (a) is strictly more reachable than site (b): snapshot() runs on EVERY stateful auto-upgrade;
restore() only after an unhealthy release. Builder's "no unhealthy release needed" is correct.
- Arming condition is real: keycloak has WARM_CANONICAL=True at 07fc6d4 too, so one pre-fix seed writes
domain=warm-canon-keycloak into the bare-recipe slot and arms BOTH sites post-merge.
- Blast radius exactly one unit: keycloak is the only WARM_DOMAINS member and the only stateful SPEC.
Probe with the reconciler's exact args: site (a) raises SnapshotError before docker (CONFIRMED); an
unclaimed slot passes the guard (why it's unreachable on cc-ci today); site (b) dies on docker at
_assert_undeployed (:205) upstream of the guard (:209) — independently reproducing the Builder's probe
caveat, same class as the e3b0c44298fc1c14 empty-input tell.
Accept the correction that b5f2b10 ADDS a raise path rather than only closing one; what makes it
unreachable today is node state, not F-redfix-4's closure.
Verdict: do not revert the widening. Precondition stands and covers both sites. Merge target b5f2b10
unchanged. M1+M2 PASS stand, DONE stands, no VETO. B-redfix-5 deferred (now correctly scoped);
B-redfix-8 unchanged. ADVERSARY-INBOX consumed + deleted.

Broke the pattern of re-probing B-redfix-8 (wakes #37-40, operator-only, adds nothing) and instead
attacked the artefact the operator acts on: "merge b5f2b10, NOT 07fc6d4".
Applied this phase's own lesson — verifying a fix's stated invariant beats verifying its shas, and
mutation-testing is what makes a "+N tests" claim meaningful.
- Lineage: b5f2b10 = 07fc6d4 + exactly the F-redfix-4 fix; fix symbols absent at 07fc6d4.
- Reproduced the pre-fix defect cold (stdlib only; no pytest/awk/curl on orchestrator, no python3 on
cc-ci): both canonical + live reconciler resolved to <root>/keycloak/snapshot, no guard.
- Invariants GREEN at b5f2b10. Mutation A (canonical_ns -> bare recipe) and Mutation B (guard -> no-op)
each go RED on exactly the right invariant; mutation A leaves the non-provider invariant PASS, so the
probe is specific, not globally fragile.
- Guard is wired into both destructive paths, ahead of the destructive work. Drove the real F-redfix-4
scenario through the PUBLIC api: refused, live known-good intact.
- Disbelieved then confirmed two Builder claims: "10 new tests" (exactly 10, coverage matches) and
"no migration on cc-ci" (keycloak slot holds only last_good, no canon-* slot) — the latter is
load-bearing because the fix ADDS a way for restore() to raise, and B-redfix-5 leaves the rollback
restore() outside the try/except. Unreachable today; recorded as a merge precondition.
- B-redfix-5 re-verified accurate at b5f2b10 (warm_reconcile.py:533-537).
- "Zero blast radius": 8/8 sampled canonicals on cc-ci record domain=warm-<recipe>, guard passes.
Verdict: merge guidance CONFIRMED. No new finding. M1+M2 PASS stand, DONE stands, no VETO.
B-redfix-8 unchanged (OPEN/HIGH/operator-rotation-only, not re-probed by design); B-redfix-5 deferred.

Builder's 697959d responds to wake #39 by hardening STATUS's B-redfix-8 close-criteria against the false-close hazard I filed. Re-verified all four quantities from a cold start: empty-input tell e3b0c44298fc1c14; .testenv absent on cc-ci (python3 also absent there); rotation sentinel 3fcea78925015fc9 STILL UNROTATED; public 2ad38f5 blob HTTP 200/33408/sha256 1994fd8d matching git object, with the live GITEA_PASSWORD present VERBATIM in the public body (value-level). The hardening is correct and worthwhile. No new finding, no verdict change. M1+M2 PASS stand, DONE stands, no VETO. B-redfix-8 stays OPEN/HIGH/operator-rotation-only.

Probed the one claim in b5f2b10 that is empirical rather than diff-checkable: "no migration on
cc-ci; keycloak's canonical was never seeded". If false, the new _assert_slot_not_foreign() guard
would wedge the live-warm reconciler's snapshot() on every stateful keycloak auto-upgrade.
Cold, read-only on cc-ci: keycloak/ + traefik/ hold only last_good (never seeded — claim TRUE);
all 17 existing canonical metas carry domain=warm-<recipe> and none is in WARM_DOMAINS, so the
guard passes unchanged (backward compatible); the dropped meta["recipe"] key has no consumer;
slot<->stack is 1:1 over all 21 enrolled recipes with live/canonical disjoint exactly for
WARM_DOMAINS; prune_stale's keep-set covers all 17 dirs and skips keycloak/ structurally.
No new finding. Merge target redfix-m2-harness@b5f2b10 unchanged. Loop stopped.

A bare '## VETO —' heading still matched a grep for a standing veto even though it was
cleared at 00:18Z, and the Builder's DONE rests on 'no standing VETO'. Annotated the
original heading in place (history preserved) and made '## VETO CLEARED' a heading rather
than bold text. No verdict changes: M2 PASS stands, F-redfix-4 stays CLOSED.
Cold-verified redfix-m2-harness@b5f2b10 (parent 07fc6d4 = the sha the earlier M2 PASS was
given against, so the other five fixes are provably untouched by this commit).
Clearing condition MET verbatim: live_slot=keycloak vs canonical_slot=canon-keycloak are
disjoint; restore(canon) and restore(live) each return their OWN stack's volumes; reconciler
last_good survives; foreign snapshot AND foreign restore both refused (probed both directions).
canonical_domain unchanged, so M2's original keycloak evidence still stands.
Checks the Builder did not run:
- integrity: canon mariadb byte-identical across the destructive restore round-trip
(cksum 4271926745 166164480, 386 files, before and after).
- mutation testing (are the +10 tests vacuous?): reverting canonical_ns() to `return recipe`
reds 4 of them; removing both _assert_slot_not_foreign() call sites reds 2. Not vacuous.
Suites reproduce exactly: 325 passed @b5f2b10, 315 passed @07fc6d4.
- caller audit: every snapshot/restore/app_dir/snap_dir call site passes an explicit slot;
no bare recipe survives.
- blast radius (the risk this refactor most plausibly created): all 21 enrolled recipes still
resolve to their EXISTING on-disk dirs; registry_path("bluesky-pds") is character-identical
at parent and fix. The 3 without a registry have no dir at all and never did. No migration.
- prune_stale invariant now structural: <recipe>/ never gains a canonical.json, so a
de-enrolled provider can no longer rmtree the reconciler's last_good (scratch-root sim,
fake ns only — prune_stale calls `docker volume rm`).
Enrollment retained (WARM_CANONICAL=True), no silent de-enrollment. Both false
"can never touch each other" comments removed.
B-redfix-5 (reconciler rollback restore() outside the upgrade try/except) accepted as
NON-BLOCKING: verified verbatim present at parent 07fc6d4, so it predates the enrollment.
F-redfix-4 made it reachable; that path is now closed. Correctly filed, not silently fixed.
All six recipes now hold a fresh Adversary PASS; F-redfix-1/2/3/4 CLOSED; no open blocking
finding. Builder may re-assert ## DONE.
Node clean: throwaway volume + scratch removed, real warm root untouched (keycloak/ = last_good
only, no canon-keycloak/ created), canon volumes intact, live keycloak /realms/master 200 throughout.
Post-reboot re-confirmation #8. New break-it probe on the two HARNESS fixes (previously
only sha-reachability checked, never content, never second-order effects).
mumble 07fc6d4: CLEAN — attempts 12->36 @5.0s = claimed 180s; all assertions unchanged,
so a dead server still FAILs. Budget widened without weakening the test.
keycloak 61211db: correct at the domain/stack layer, but its own invariant is FALSE.
canonical_domain() separates the two deployments by domain, yet warm STATE is keyed by
recipe: warmsnap.snap_dir("keycloak") is ONE slot shared by the live-warm reconciler
(warm-keycloak, stateful=True) and the newly-enrolled data-warm canonical
(warm-canon-keycloak, seeded via promote_canonical -> seed_canonical, no WARM_DOMAINS guard).
Proved by execution on cc-ci in a scratch CCCI_WARM_ROOT against the real idle canon stack:
snapshot(canon) -> snapshot(other stack) destroys the canonical known-good, and
restore(canon) raises SnapshotError. Fails closed (no cross-stack data write), but:
1. every stateful reconciler upgrade deterministically destroys the canonical snapshot;
2. the reconciler's rollback restore() is OUTSIDE its try/except and its snapshot->restore
window spans deploy+wait_healthy (health_timeout 900). A sweep promote landing there makes
the rollback raise AFTER abra.undeploy(live) -> live keycloak left undeployed = outage of
the shared OIDC provider lasuite-*/drone depend on. Exactly the hazard canon §2.B's
de-enrollment exception existed to prevent.
3. prune_stale()'s documented "keycloak untouched" invariant becomes false once seeded.
Undetectable by the M2 run: /var/lib/ci-warm/keycloak/ holds only last_good (no canonical.json,
no snapshot/) vs cryptpad which has both — the promote deployed but seed_canonical never ran,
registry-advance being deferred to the operator's merge. First seed happens post-merge, unexercised.
VETO scoped to keycloak. M1 classifications and the discourse/mattermost-lts/gitea/bluesky-pds/
mumble fixes are unaffected and remain PASS. Clears when the two deployments use disjoint
warm-state paths and each restore() returns its own stack's volumes.
Node left clean: real warm root untouched, volumes intact, live keycloak 200 throughout.
