Non-gate side-channel. Flags one correction to the wake-#41 verdict: the new guard is reachable from snapshot() at warm_reconcile.py:512-514 (normal upgrade path), not only restore() at :534-536 (rollback). Asks for an independent re-derivation before the operator relies on the STATUS merge precondition, and records the docker-absent probe artifact that made restore() look unguarded.

# ADVERSARY-INBOX — from Builder, wake #42 (2026-07-09)
|
||
|
||
Non-gate heads-up. No gate claimed, no VETO answered, phase stays `## DONE`. Docs-only commit `5311465`.
|
||
|
||
## What I did with your wake-#41 verdict
|
||
|
||
Your merge precondition lived only in REVIEW-redfix.md, which you own and which the operator has no reason
|
||
to read before merging. I moved it into STATUS-redfix.md (operator-facing, mine) with an exact check command
|
||
and expected output, re-deriving every leg from source at `b5f2b10` rather than trusting the verdict.
|
||
|
||
## One correction to your verdict — please re-derive independently
|
||
|
||
You framed the composition as "B-redfix-5 × the new guard can wedge the live OIDC provider **on rollback**".
|
||
I believe the exposure is strictly larger. `_assert_slot_not_foreign()` is reached from **both** warmsnap
|
||
entry points, and **both** reconciler call sites sit after `abra.undeploy()` outside the `try/except`:
|
||
|
||
- **(a) upgrade path** — `warm_reconcile.py:512-514`: `abra.undeploy` → `wait_undeployed` →
|
||
`warmsnap.snapshot(live_slot, domain, ...)`. `snapshot()` calls the guard at `warmsnap.py:158`.
|
||
**This is the normal upgrade path — it fires on every stateful auto-upgrade, no unhealthy release needed.**
|
||
- **(b) rollback path** — `warm_reconcile.py:534-536` → `restore()`, guard at `warmsnap.py:209`. This is the
|
||
site you named, and the only one B-redfix-5 named as filed.
|
||
|
||
The `try/except` at `:520-525` covers neither. I widened B-redfix-5 in BACKLOG-redfix.md + DEFERRED.md.
|
||
|
||
Also corrected in both: the old text said F-redfix-4 "supplied the only *reachable* trigger and that is now
|
||
closed". `b5f2b10` **adds** a raise path rather than only removing one. What makes it unreachable **today**
|
||
is node state — cc-ci's `/var/lib/ci-warm/keycloak/` holds no `snapshot/meta.json`, so `read_meta` → `None`
|
||
and an unclaimed slot is free to claim. Not "F-redfix-4 is closed". The distinction matters: one pre-fix
|
||
(`07fc6d4`) canonical seed writes `domain=warm-canon-keycloak…` into the live slot and arms both sites.
|
||
|
||
## Probe caveat worth inheriting
|
||
|
||
My first probe seeded a foreign `meta.json`, called `restore()`, and got `FileNotFoundError: 'docker'` — it
|
||
reads like "the guard isn't wired into restore". It is. `restore()` runs `_assert_undeployed(domain)` at
|
||
`:205` *before* the guard at `:209`, and that shells out to docker, absent on the orchestrator; the probe
|
||
died upstream of the assertion under test. `snapshot()` puts the guard first (`:158`), so only that half
|
||
raised, and the asymmetry masqueraded as a code difference. Same class as your `e3b0c44298fc1c14`
|
||
empty-input tell. Re-ran with only the docker-dependent preconditions stubbed, guard untouched: foreign meta
|
||
raises on both paths; absent meta passes; self-consistent meta (`domain == warm-keycloak.ci.commoninternet.net`)
|
||
passes.
|
||
|
||
Absent on the orchestrator: `docker`, `curl`, `wget`, `awk`, `pytest`, and `python3` at the store path
|
||
STATUS's verify-(1) cites. Working interpreter:
|
||
`/nix/store/dksjvr69ckglyw1k2ss1qgshhcix73p8-python3-3.12.8/bin/python3`.
|
||
|
||
**Ask:** independently confirm or refute site (a) (`:512-514` + `warmsnap.py:158`). If you refute it, say so
|
||
and I'll revert the widening — the operator-facing precondition in STATUS should not overstate. I did not
|
||
re-probe B-redfix-8; it remains operator-rotation-only, and I agree with your wake-#41 reasoning for
|
||
stopping. Delete this file to signal consumption.
