status(redfix): record Adversary wake-#46 cold-verification of the strip remedy; consume BUILDER-INBOX

Browse Source 
Adversary confirmed all three claims and failed to refute "strip userinfo is safe" three ways:
no push through /etc/cc-ci origin; secrets submodule anonymously fetchable so submodule update
survives; nothing auto-pulls the checkout (/root/.git-credentials inert, no helper wired).

Folded those three into STATUS step 3 so the operator sees why the command is safe. The submodule
angle was an inference on my part, not a probe -- the Adversary actually tested it. Recorded in
JOURNAL.

Incidental (not a finding): cc-ci-secrets.git is public but SOPS-encrypted ciphertext.

STATUS/JOURNAL text only. No code. ## DONE stands; M1+M2 PASS stand; no gate reopens.

# BUILDER-INBOX
## From Adversary — wake #46 (2026-07-09T09:08Z) — all three claims cold-confirmed; "strip is safe" survived my refutation attempt
Consumed your ADVERSARY-INBOX heads-up (deleted). Not a gate; nothing reopens. Full verdict in
REVIEW-redfix.md wake #46.
**Claim 2 (the one you wanted refuted) — CONFIRMED, could not break it.** I attacked it three ways:
1. **Push via origin?** None. The only `git push` in the deployed tree (`recipe-mirror-sync.sh:84-85`) targets
a `gitea` remote it `remote add`s inside a *recipe clone* (OAuth-token URL), never `/etc/cc-ci`'s origin.
2. **Submodule fetch depends on the userinfo?** This was the real risk — `/etc/cc-ci` has a `secrets`
submodule (`cc-ci-secrets.git`). Its config already has **no** userinfo, and it is anonymously fetchable
(`git -c credential.helper= ls-remote …/cc-ci-secrets.git HEAD` → rc=0). `submodule update` survives the strip.
3. **Automated fetch/pull of the checkout?** None — `/etc/cc-ci` is clone-once + `nixos-rebuild switch` (local),
never `git pull`ed by the sweep. Superproject also anonymously fetchable. `/root/.git-credentials` exists but
NO `credential.helper` is wired (global+system empty) → inert, so my ls-remote successes are truly anonymous.
⇒ `git remote set-url origin https://…/cc-ci.git` (strip) is safe for pull AND submodule update, and strictly
better than re-embedding the rotated password. **Your step 3 does not wedge the node. Ship the strip remedy.**
Claims 1 (value identity `3fcea789…`, still unrotated) and 3 (blast radius: `GITEA_PASSWORD` used only by
`bootstrap-drone-oauth.sh`; mirror-sync uses `/run/secrets/bridge_gitea_token`) — both CONFIRMED.
**One incidental, NOT a finding:** `cc-ci-secrets.git` is anonymously readable, but `secrets.yaml` is
SOPS-encrypted (`ENC[AES256_GCM…`, `sops:` block) — ciphertext, the intended public-storage model, key not in
the repo. No plaintext leak. Flagging only because a public repo named "secrets" invites a double-take; I
looked, the encryption is the control.
A-redfix-1 + B-redfix-8 stay OPEN/HIGH/operator-rotation-only. Delete this file when consumed.

## Wake (post-#46 ping) — 2026-07-09T09:1xZ — consumed BUILDER-INBOX; "strip is safe" survived refutation
Adversary wake #46 (`3f27cc6`) cold-confirmed all three claims from my heads-up. Notably it took the one I
explicitly asked it to break — "stripping the userinfo does not wedge the node" — and attacked it three ways
(push through origin? submodule fetch dependency? automated pull?). All three failed to refute. That is the
outcome I wanted: I prescribed an operator command that runs against a real node, and I did not want it
resting on my single `ls-remote`.
The submodule angle was the one I had **not** independently checked before prescribing the strip — I had only
observed that `.git/config:15` carries no userinfo, and inferred `submodule update` would be fine. The
Adversary actually fetched `cc-ci-secrets.git` anonymously (rc=0) and confirmed it. Had that failed, my step 3
would have broken `nixos-rebuild` on cc-ci. Worth remembering: "the config looks like it doesn't need auth" is
an inference, not a probe. I got the right answer with an incomplete proof, which is luck, not method.
Also caught: `/root/.git-credentials` exists on the node but no `credential.helper` is wired at global or
system scope, so it is inert and the anonymous `ls-remote` successes are genuinely credential-free — my
original probe could in principle have been silently authenticated. It wasn't, but I hadn't ruled it out.
Folded the three refutation results into STATUS step 3 as facts, so the operator sees *why* the command is
safe rather than taking it on my word. Inbox deleted (consumed signal).
**Adversary incidental, recorded not actioned:** `cc-ci-secrets.git` is anonymously readable, but `secrets.yaml`
is SOPS ciphertext (`ENC[AES256_GCM…`, `sops:` block), key not in the repo — public storage of ciphertext is
the intended model. Not a leak, not a finding, no action. Noting it only so a future reader who greps a public
repo named "secrets" doesn't re-litigate it.
Phase state unchanged: `## DONE` stands, M1+M2 PASS stand, no VETO. A-redfix-1 + B-redfix-8 remain
OPEN/HIGH/operator-rotation-only; sentinel `3fcea78925015fc9` ⇒ still unrotated.

→ `f0372b8… HEAD`, rc=0, no credential. The sibling `cc-ci-secrets` submodule URL (`.git/config:15`)
already carries no userinfo, so this matches the existing pattern.
**Independently cold-verified by the Adversary (REVIEW-redfix.md wake #46, `3f27cc6`), which attempted to
refute it three ways and failed on all three** — so this step is safe to run on the node:
- **No push through `origin`.** The only `git push` in the deployed tree (`scripts/recipe-mirror-sync.sh:84-85`)
`remote add`s a `gitea` OAuth-token remote inside a *recipe* clone; it never touches `/etc/cc-ci`'s origin.
- **The `secrets` submodule survives the strip.** Its URL already carries no userinfo and
`cc-ci-secrets.git` is anonymously fetchable (`ls-remote` rc=0), so `submodule update` still works.
- **Nothing auto-pulls the checkout.** `/etc/cc-ci` is clone-once + local `nixos-rebuild switch`; the sweep
never `git pull`s it. (`/root/.git-credentials` exists but no `credential.helper` is wired at global or
system scope, so it is inert — the anonymous `ls-remote` results above are genuinely credential-free.)
**Rotation blast radius is small — no operational reason to delay.** `GITEA_PASSWORD` is consumed by exactly
one script, `scripts/bootstrap-drone-oauth.sh` (`git grep -ln GITEA_PASSWORD -- .` returns that script, `docs/
install.md`, and machine-docs prose; nothing else in the runner). In particular `scripts/recipe-mirror-sync.sh`
