+Inputs for verification:
+- Implementation commit: `44e0242` (`feat(cfold): canonicalize custom test layout`)
 
 Completed in this checkpoint:
 - discovery.py: `custom/` canonical + deprecated aliases with warnings
@@ -17,13 +22,30 @@ Completed in this checkpoint:
 - unit tests updated (`test_discovery.py`, `test_discovery_phase2.py`, `test_manifest.py`)
 - manifest.py now reports canonical `custom` counts
 
-Verification so far:
-- `nix shell nixpkgs#python312Packages.pytest --command pytest tests/unit/test_discovery.py tests/unit/test_discovery_phase2.py tests/unit/test_manifest.py -q`
-- Expected/current: `18 passed`
+WHAT:
+- M1 implementation is complete: custom-test discovery is canonicalized to `custom/`, deprecated
+  aliases warn loudly instead of silently dropping coverage, all cc-ci custom tests/helpers moved to
+  `tests/<recipe>/custom/`, manifest counts are canonicalized, and the placement-rule docs/unit tests
+  were updated.
 
-Remaining before an M1 claim:
-- assemble a cold-verifiable before/after coverage proof (same discovered custom-test set, paths renamed only)
-- write WHAT/HOW/EXPECTED/WHERE into this file for the Adversary
+HOW:
+- `git ls-files "tests/*/custom/test_*.py" | wc -l`
+- `git ls-files "tests/*/functional/*" "tests/*/playwright/*"`
+- `for recipe in bluesky-pds cryptpad custom-html custom-html-tiny discourse drone ghost hedgedoc immich keycloak lasuite-docs lasuite-drive lasuite-meet mailu matrix-synapse mattermost-lts mumble n8n plausible uptime-kuma; do count=$(git ls-files "tests/$recipe/custom/test_*.py" | wc -l); printf "%s %s\n" "$recipe" "$count"; done`
+- `nix shell nixpkgs#python311Packages.pytest -c pytest tests/unit/test_discovery.py tests/unit/test_discovery_phase2.py tests/unit/test_manifest.py -q`
+
+EXPECTED:
+- Total canonical custom tests: `64`
+- Old tracked trees: no output for `functional/*` or `playwright/*`
+- Per-recipe counts exactly match the baseline table below
+- Focused unit suite: `18 passed`
+
+WHERE:
+- Discovery + alias warnings: `runner/harness/discovery.py`
+- Canonical manifest counts: `runner/harness/manifest.py`
+- Migrated custom tests/helpers: `tests/*/custom/`
+- Focused unit coverage: `tests/unit/test_discovery.py`, `tests/unit/test_discovery_phase2.py`, `tests/unit/test_manifest.py`
+- Placement-rule docs: `docs/recipe-customization.md`, `docs/testing.md`, `docs/enroll-recipe.md`, `README.md`
