# REVIEW-rcust.md — Adversary ledger for the recipe-customization restructure phase

SSOT for this phase: `/srv/cc-ci/cc-ci-plan/recipe-custom-restructure-full-plan.md`.
Gates: **M1** (implementation verified — branch `restructure/recipe-custom`, unit+concurrency+lint
green on cold clone, resolved-customization diff clean for all 21 recipes, adversarial diff review)
and **M2** (merged + real-CI regression sweep matching baseline matrix). DONE requires fresh PASS
for both with no open VETO.

I own this file and the `## Adversary findings` section of BACKLOG-rcust.md only.

## Standing watch items (what I will hunt at M1/M2)

- **Coverage loss** (cardinal risk): for every migrated recipe, old loaders' effective customization
  values must equal new `meta.load()` values. Throwaway diff script over all 21 recipe dirs; any
  delta = finding.
- **Assertion weakening** in `tests/<recipe>/` diffs — migrations must be mechanical only (signatures,
  fixture/key renames, underscore prefixes). Any changed assert/expected value = VETO.
- **Deleted-code fallout** — dangling refs to `_recipe_meta`, `_load_meta`, `_recipe_extra_env`,
  `_recipe_meta_flag`, `declared_deps`, `is_canonical_enrolled`, `OIDC_AT_INSTALL`,
  `CHAOS_BASE_DEPLOY`, `SKIP_GENERIC`, `setup_custom_tests`, `deps_apps`, `deps_creds`, `deployed_app`.
- **Validation gaps** — typo'd key / wrong type / callable-on-data-key must raise MetaError, not pass.
- **R2 fixed end-to-end** — orchestrator load path delivers SCREENSHOT to screenshot.py.
- **HC2 / F2-11 integrity** — repo-local default-deny, requires_deps skip-report, generic floor
  semantics all unchanged.

## Verdicts

_(no GATE verdict yet — M1 is not claimed. M1 only claims after P1–P6 are all on the branch;
Builder has landed P1 (472a68b) + P2 (8cd72fd) and is mid-P3. The interim pre-review below is
front-loaded break-it work on the FROZEN P1/P2 commits — NOT an M1 PASS.)_

### Interim pre-review of frozen P1+P2 (branch @ 8cd72fd) — @2026-06-10, cold from upstream clone

Done as idle-time break-it work while no gate is pending. P1/P2 phase commits won't be rewritten
(Builder adds P3+ on top), so reviewing them now is non-wasted and front-loads M1. Cold clone of
`origin/restructure/recipe-custom` into `/tmp/rcust-verify` from the true upstream remote.

**No defects found so far.** Results:

1. **Deleted-code fallout — CLEAN.** Grepped `runner/ tests/ scripts/` for live refs to every deleted
   symbol (`_recipe_meta`, `_load_meta`, `_recipe_extra_env`, `_recipe_meta_flag`, `declared_deps`,
   `is_canonical_enrolled`, `OIDC_AT_INSTALL`, `CHAOS_BASE_DEPLOY`, `SKIP_GENERIC`,
   `setup_custom_tests`, `deps_apps`, `deps_creds`, `deployed_app`). All hits are comments/docstrings
   explaining the deletion, test names, or the intentionally-RETAINED `CCCI_SKIP_GENERIC*` env form
   (kept per P2c). Zero live call-sites. `setup_custom_tests.sh` files gone.
2. **All-recipes-load-clean (typo gate) — PASS, independently.** Ran `meta.load()` (pure stdlib) over
   all 21 recipe dirs cold via plain python3 (did NOT trust the Builder's test_meta.py). All 21 load;
   non-default key sets sane. Every ALL-CAPS key used in any recipe_meta.py is in the 14-key registry.
3. **Coverage-loss diff (CARDINAL check) — ZERO deltas on data keys + hook presence.** Throwaway
   harness (`/tmp/diff_meta.py`) reproduces main's six-loader effective resolution (`_load_meta`,
   `declared_deps`, `is_enrolled`, `_recipe_extra_env`) from MAIN's recipe_meta files and diffs vs the
   BRANCH's `meta.load()` for all 21 recipes. After correcting one harness artifact (EXTRA_ENV default
   is `{}` not None), **0/21 recipes show any delta** for HEALTH_PATH/HEALTH_OK/DEPLOY_TIMEOUT/
   HTTP_TIMEOUT/BACKUP_CAPABLE/EXPECTED_NA/UPGRADE_BASE_VERSION/DEPS/WARM_CANONICAL + presence of
   READY_PROBE/BACKUP_VERIFY/UPGRADE_EXTRA_ENV/EXTRA_ENV/SCREENSHOT.
4. **Validation gaps — CLOSED.** Crafted tmp recipe_metas: typo'd key → MetaError (with "did you mean
   DEPLOY_TIMEOUT?"); wrong type (`DEPLOY_TIMEOUT="str"`) → MetaError; callable on data key
   (`DEPLOY_TIMEOUT=lambda ctx:...`) → MetaError; `_PRIVATE`/lowercase-helper → loads clean (exemption
   works). All four behave per the locked decision.
5. **meta.py read** — single `exec()`, frozen `RecipeMeta` generated from `KEYS`, `_coerce` rejects
   bool-as-int and callable-on-data-key; `non_default` compares vs registry default. No issues.

**Still UNVERIFIED for M1 (do NOT treat above as M1 PASS):** full `pytest tests/unit -q` +
`pytest tests/concurrency -q` + `scripts/lint.sh` cold on the cc-ci host; R2 end-to-end through the
real orchestrator screenshot path; P3 ctx-hook signature migration (assert byte-identical, legacy
`lambda domain:` raises clear MetaError); P4/P5/P6; re-run the coverage diff on the FINAL branch
(P3 changes hook signatures); recipe-test diffs are mechanical-only (no assertion weakening);
HC2/F2-11/generic-floor integrity. These wait for the `claim(rcust): M1`.
