+## W2: PASS @2026-05-27 16:55Z — secrets-split + cert-in-git (verifies C1, C2, C3) — COLD
+
+Gate W2 CLAIMED by Builder (commits `f972bc1`/`f79e542`/`faa3709`; running toplevel `vh6vwxbl…`). Verified independently from a cold start (fresh clone on cc-ci, own checks, no reliance on the Builder's `/root/cc-ci`):
+
+**(1) Byte-identical build==running (C1) — PASS.** Fresh recursive clone of `origin/main` (HEAD `0633aa7`) on cc-ci into `/tmp/advverify`, submodule `secrets`→`2312f1c` initialized with bot creds (via `http.extraheader`, not URL/args), `secrets/secrets.yaml` present + `ENC[…]`. `nixos-rebuild build --flake 'git+file:///tmp/advverify?submodules=1#cc-ci'` → `/nix/store/vh6vwxbl4qr9whzpwgjimhf9gn4329p8-nixos-system-…` == `/run/current-system` (`readlink -f` identical). **Zero drift** — the *currently published* repo+submodule reproduces the *currently running* system byte-for-byte. Base stays one parameterized repo; only `secrets/` is the external private submodule.
+
+**(2) Cert in git + live TLS (C2) — PASS.** `/var/lib/ci-certs/live/{fullchain.pem,privkey.pem}` are now **symlinks → `/run/secrets/wildcard_cert`,`wildcard_key`** (sops-decrypted at activation), not out-of-band files. File sha256 `c1d96d61…`/`9ec25d00…` == my pre-W2 operator-cert baseline (byte-identical cert, now git-sourced). `secrets.nix` adds `wildcard_cert`(0444)/`wildcard_key`(0400) with a comment that this "Replaces the prior operator-drops-a-cert-file step." Live HTTPS `https://ci.commoninternet.net` via proxy → `http_code=200`, `ssl_verify_result=0`, served leaf = LE `*.ci.commoninternet.net` (SAN `*.ci`+bare), valid 2026-05-26→08-24. **Served leaf fingerprint `57:8D:67:9E:FE:89:…:B8:A6` == the git-sourced cert's leaf fingerprint** (computed locally from the decrypted file) → live TLS provably served from the git cert, full chain of custody intact.
+
+**(3) No plaintext leak (C3) — PASS.** Base repo: `secrets/` is a gitlink (`.gitmodules`→ private `cc-ci-secrets`); no `*.pem/*.key` tracked; `git grep BEGIN…PRIVATE KEY|CERTIFICATE` outside REVIEW text = 0. `cc-ci-secrets`: all 8 secrets `ENC[…]` (6 infra + cert + key), 0 plaintext PEM, valid sops MAC, private repo. On the host: secrets decrypt to **`/run/secrets.d` (ramfs, in-memory)**, not the world-readable store; no private key found in the system-closure store dirs.
+
+**Non-regression:** `systemctl is-system-running`=running, **0 failed units**; swarm stack all 1/1 (`traefik` v3.6.15, `drone` 2.26.0, `ccci-bridge`, `ccci-dashboard`, `backups`), `drone-runner-exec` running; reconcile oneshots converged. No D1–D10 regression observed.
+
+→ **C1, C2, C3 Adversary-PASS** (24h freshness clock starts now; will be re-exercised on the blank host at C4). Remaining for DONE: C4 (genuine throwaway-VM live rebuild), C5 (honest D8), C6 (resize+cleanup), C7 (docs). No VETO.
