fix(redfix): B-redfix-8 exposure UNDERSTATED — password is served by TWO published commits (2ad38f5 + e64d8e7), not one; oauth2 token is NOT in git history (0/3099 blobs)

Closes the gap in Adversary wake #57's break-it probe, which covered dashboard/reports/Drone
logs but not the public git mirror -- the surface B-redfix-8 is about.

- password sha16 3fcea78925015fc9 -> 2 blobs, 2 commits, both ancestors of origin/main.
  Scrubbing 2ad38f5 alone would leave e64d8e7 serving the live credential. STATUS corrected.
- oauth2 token sha16 9c44a1aea2ecb389 -> 0/3099 blobs. Filesystem-only exposure.
- Probe hygiene: awk is absent here; awk-based blob lists give a vacuous 0. Positive
  control (password must return 2) is now mandatory and documented.

Operator-scope, no gate impact, no VETO; DONE stands.

+**CORRECTED (wake #58, 2026-07-09):** an earlier version of this entry said "**only** the historical commit
+`14c7dee` serves it." That **understated the exposure**. An exhaustive scan of all **3099** blobs in the
+object db (`git cat-file --batch-all-objects`, literal-value match) finds the password in **two distinct
+blobs**, carried by **two published commits** — both ancestors of `origin/main`, so both are mirror-served:
+
+| commit | blob | `machine-docs/BACKLOG-redfix.md` size |
+|---|---|---|
+| `14c7dee` | `fd21fcb8ac02bff9917531c8175a29e450c41b19` | 33408 |
+| `223cc16` | `bcc31b55860f782056ba3ccdf13165191bd329b5` | 34353 |
+
+Neither blob is reachable from HEAD. Scrubbing only `14c7dee` would leave `223cc16` serving the credential.
 
 **WHERE.** `git.autonomic.zone/recipe-maintainers/cc-ci` →
-`/raw/commit/14c7dee/machine-docs/BACKLOG-redfix.md`
+`/raw/commit/14c7dee/machine-docs/BACKLOG-redfix.md` **and**
+`/raw/commit/223cc16/machine-docs/BACKLOG-redfix.md`
 
 **HOW to confirm exposure** (unauthenticated fetch; a raw blob at a fixed sha is immutable, so served size
 must equal object size):
 
     git cat-file -s 14c7dee:machine-docs/BACKLOG-redfix.md    # → 33408
+    git cat-file -s 223cc16:machine-docs/BACKLOG-redfix.md    # → 34353
 
-An unauthenticated fetch of the raw URL returning **HTTP 200 / 33408 bytes** is the leak, not an error page.
+An unauthenticated fetch of **either** raw URL returning **HTTP 200** at the matching byte count is the
+leak, not an error page.
+
+**Exhaustive-scan reproduction** (names/counts only; never prints the value). The `awk`-free form matters —
+`awk` is absent on the orchestrator and an `awk`-based blob list yields an **empty** list, i.e. a vacuous
+`0 hits`:
+
+    git cat-file --batch-all-objects --batch-check='%(objecttype) %(objectname)' \
+      | grep '^blob ' | cut -d' ' -f2 > /tmp/blobs        # → 3099 lines; assert >100 before trusting
+    # then literal-match each blob against a chmod-600 sentinel; positive control MUST return 2
+
+**Positive control is mandatory.** Any scan of this repo that reports **0** password-bearing blobs is a
+**broken probe**, not a clean repo — the correct answer is **2**.
+
+**The `oauth2` token (the second exposed credential) does NOT appear in git history.** Same exhaustive scan,
+same run, literal match against the live token (`sha256[:16]=9c44a1aea2ecb389`, extracted root-only to a
+`chmod 600` file, then `shred`-removed): **0 of 3099 blobs.** The 271 history blobs matching the string
+`oauth2:` are `scripts/recipe-mirror-sync.sh:39`'s `https://oauth2:${TOKEN}@…` **variable interpolation**
+plus machine-docs **prose citing the sha16 sentinel** — no literal value. So the token's exposure is
+**filesystem-only** (A-redfix-1: world-readable `.git/config` copies); it is **not** on the public mirror.
+The password's exposure is **both** filesystem **and** public mirror. The two credentials differ in blast
+radius; the operator remedy must not treat them as symmetric.
 
 **HOW to confirm it is still the live credential** (commits to the value without republishing it).
 Run this **on the orchestrator** — `/srv/cc-ci/.testenv` lives there, **not** on `cc-ci`:
