+Helper modules also in functional/ dirs (must move to custom/ alongside tests):
+- tests/discourse/functional/_discourse.py
+- tests/drone/functional/__init__.py
+- tests/ghost/functional/_ghost.py
+- tests/mailu/functional/_mailu.py
+- tests/mattermost-lts/functional/_mm.py
+- tests/mumble/functional/_mumble_proto.py
+
+**String literal audit** — all places that name the FOLDER (not the playwright package):
+- runner/harness/discovery.py:113 — `subdirs = ("functional", "playwright")`
+- runner/harness/manifest.py:55 — comment `# functional | playwright`
+- docs/recipe-customization.md — multiple §5.3 references
+- docs/enroll-recipe.md — multiple references
+- docs/testing.md:117,120 — placement rule
+- tests/unit/test_discovery_phase2.py — creates functional/ and playwright/ dirs
+- tests/unit/test_manifest.py — creates functional/ and playwright/ dirs; asserts `{"functional": 2, "playwright": 1}`
+- tests/unit/test_discovery.py:83,84 — creates functional/ dirs
+
+NOT to touch (playwright package references, not folder):
+- runner/harness/browser.py (playwright package import)
+- runner/harness/screenshot.py (playwright package import)
+- runner/harness/card.py:232 (playwright package import)
+- level.py, results.py (rung name "functional" — NOT a folder name)

+# REVIEW — Adversary — phase cfold
+
+Adversary-only. Append-only. All verdicts here are cold-verified from a fresh shell + own clone.
+SSOT for what is being verified: /srv/cc-ci/cc-ci-plan/plan-phase-cfold-custom-folder.md

+
+## 2026-06-11T22:54Z — Adversary initialized; awaiting Builder M1 claim
+
+Baseline recorded in BACKLOG-cfold.md (pre-migration inventory).
+No claims pending. Will verify M1 and M2 on Builder claim.
+
+Key break-it probes planned:
+1. Grep codebase for any remaining `functional/` or `playwright/` folder-name string literals after M1.
+2. Run discovery cold to confirm no test was dropped (count must equal 64 custom test files).
+3. Verify deprecated-alias warning fires when a test is in old folder (per plan §2.1 recommendation).
+4. Confirm `from playwright.sync_api` references NOT touched (they reference the package, not a folder).
+5. Verify unit tests are updated (test_discovery_phase2.py, test_manifest.py) and still pass.
+6. Confirm manifest.py custom_counts changes correctly (sub will be "custom" not "functional"/"playwright").
+7. Confirm RUNG name "functional" (L4) is NOT renamed — only the folder name changes.
+8. M2: real Drone !testme sweep across all enrolled recipes — same level, same tests, zero leaks.
