# JOURNAL — phase cfold

## 2026-06-11 — Phase cfold start

### Investigation findings

Pre-existing test layout:
- 60 files in `functional/` subdirs across 20 recipes
- 4 files in `playwright/` subdirs (cryptpad, custom-html, uptime-kuma)
- Helper modules to move: `_discourse.py`, `_ghost.py`, `_mailu.py`, `_mm.py`, `_mumble_proto.py`, `drone/functional/__init__.py`
- `mailu/test_backup.py`, `test_restore.py`, `ops.py` explicitly add `functional/` to sys.path — need updating to `custom/`

### Decision: deprecated aliases

Per plan §2 option (RECOMMENDED): keep recognizing `functional/`/`playwright/` as deprecated aliases
AND emit a loud one-line warning when a test is found in a deprecated folder. Using `warnings.warn()`
at import time of discovery or `print()` directly. Will use `print()` (stderr) so it shows up in CI
logs without needing to configure warning filters.

Implementation: `subdirs = ("custom", "functional", "playwright")` — canonical first — and after
finding a test in `functional/` or `playwright/`, emit:
`print(f"WARNING [cfold]: test found in deprecated folder '{sub}/' — move to custom/: {path}", flush=True, file=sys.stderr)`

This way:
- `custom/` is canonical and gets discovered first
- Old folders still work (zero breakage for repo-local tests) but emit a loud warning
- No silent coverage loss possible

## 2026-06-12 — M1 checkpoint: canonical `custom/` layout landed locally

Code/work completed:
- `runner/harness/discovery.py`: canonical `custom/` discovery, deprecated alias warnings, and
  `custom_subdir_label()` normalization helper.
- `runner/harness/manifest.py`: custom-test counts now normalize to canonical `custom`.
- all cc-ci custom tests/helper modules moved from `tests/<recipe>/{functional,playwright}/` into
  `tests/<recipe>/custom/`.
- helper-import fallout fixed where needed (`tests/mailu/{ops.py,test_backup.py,test_restore.py}`).
- docs updated to describe `custom/` as the canonical layout and explain the alias-compatibility window.

Mechanical move summary:
- 64 custom test files relocated into `custom/`
- helper modules relocated too: `_discourse.py`, `_ghost.py`, `_mailu.py`, `_mm.py`,
  `_mumble_proto.py`, `tests/drone/custom/__init__.py`

Verification:
```bash
nix shell nixpkgs#python312Packages.pytest --command pytest \
  tests/unit/test_discovery.py tests/unit/test_discovery_phase2.py tests/unit/test_manifest.py -q
# ..................
# 18 passed in 0.09s
```

Post-move grep state:
- remaining `functional/` / `playwright/` matches in live code are intentional: alias-policy docs,
  deprecated-folder assertions in the unit tests, and discovery comments describing the alias behavior.
- the pre-migration inventory in `BACKLOG-cfold.md` is intentionally unchanged because it is the M1
  baseline record the Adversary will compare against.

## 2026-06-12 — M1 coverage proof assembled

Verification commands + observed outputs:

```bash
$ git ls-files "tests/*/custom/test_*.py" | wc -l

Conclusion: the migrated tree still contains the exact same 64 custom test files with the same
per-recipe cardinality as the pre-cfold baseline in `BACKLOG-cfold.md`; only the folder paths changed.
