Files that cannot be read in one piece force re-reads and partial edits,
which is the largest avoidable cost in an LLM-assisted workflow. This adds
the enforcement side of a 250-line cap covering code AND prose.
- file_length/config.py: single source of truth for the cap and its
exemptions (generated, markup, vendored, data-ish txt), shared by both the
gate and the survey so the two cannot silently disagree.
- file_length/check.py: the check itself. Exits 1 and lists violations;
adjudication is an exit code, not a judgement call.
- scripts/check_file_length.sh: thin wrapper pre-commit calls with staged
files.
Verified against six fixtures: over-cap code fails, under-cap passes,
generated l10n (1417 lines) exempt, vendored pdfjs exempt, the 174800-line
wordlist exempt as data, and a 1101-line CLAUDE.md correctly fails since
prose is capped too.
Baseline at time of writing: 657 files over 250 lines across 29 repos.
Each repo carries a refactor_claude_todo.md prompt with its own list.

Extracts the near-identical "Sync settings" UI duplicated across 5 apps
(todo, diet_guard_app, workout_app, wake_alarm/phone_app, home_inventory)
into a single tested package. Firebase sync (primary) + optional local
backup slot; GitHub mirror UI was dropped per kuhy's explicit decision
mid-build in favor of Firebase-only, so existing apps keep their local
GitHub code untouched, just disconnected from this shared screen.
100% line coverage, flutter analyze clean under very_good_analysis.
Generalized check_no_crdt_sync_override.sh to guard any utils git
dependency (crdt_sync, sync_settings_ui), not just crdt_sync by name.

Two changes to the shared sync credential path, both driven by devices
that reported "Connected" while every sync failed.
Google sign-in (signInWithGoogle, both languages) replaces typing the
sync account's password on a fresh install. The account is linked once
from the PC with tool/link_google.py, which asserts the pinned uid --
without that assertion an unlinked identity is *signed up* rather than
refused, and the new uid is then denied every read and write by the
security rules.
The second change is the one with teeth. hasSession() is a presence
check, so a refresh token the server had revoked still read as a live
session: the desktop todo build showed "Connected" and then failed every
sync with `HTTP 400 (TOKEN_EXPIRED)`. A refresh that fails for a terminal
reason now clears the stored session, so hasSession() answers honestly.
Deliberately narrow: only TOKEN_EXPIRED, USER_DISABLED, USER_NOT_FOUND,
INVALID_REFRESH_TOKEN, INVALID_GRANT_TYPE and MISSING_REFRESH_TOKEN
clear it. A network error or a 5xx must not -- a device that signs
itself out whenever the wifi drops needs a manual sign-in on every
device to recover, which is worse than the stale banner this fixes.
Verified against the live endpoint, not just mocks: has_session flips
True -> False on a real rejection.
crdt_sync_dart 0.9.0 -> 0.10.0; the five apps pin the matching tag.

`_holds_grab` asked `grab_current() is self._root`, but our own transient
children take the grab for themselves: a posted Tk menu grabs the menu
window, so the test read "the grab was lost" and `grab_set_global()` took it
back a second later, off our own widget mid-interaction. That is what made
screen-locker's sport selector unusable while locked on 2026-07-26. The
predicate is now `grab_current() is not None` -- any window we own means the
lock still has pointer and keyboard -- and it is public, `holds_grab`, so an
embedder can ask the same question instead of re-deriving it. Anything that
does not resolve against our widget map (a Tcl-created `ttk.Combobox`
popdown, a stale name) raises `KeyError` and counts as lost: fail closed,
because losing a popdown beats believing we hold a grab we do not. The
blind spot for a second `tk.Tk()` reporting its root as "." is unchanged from
the old test, and now written down.
`_verify` and `_drain` scheduled the next tick *after* running it, so any
exception ended all re-assertion of coverage, grab and VT for the rest of the
lock -- the exact fail-open this module exists to prevent, in a file whose
docstring is a monotonicity proof. The reschedule moves into `finally`, and
the warnings only fire when the reason changes: these states can last the
whole lock, and a 1Hz journal stream is not the alternative to silence.
The pre-commit side: both subproject configs were written as if cwd were the
subproject, but pre-commit runs hooks from the git root -- which is ~/utils,
not gatelock. Every pushed run since at least 2026-07-11 has been red, and
for compounding reasons: pylint and bandit could not find their config,
bandit's tests exclusion never matched, the pytest hook ran with no config at
all, and with no `files:` filter each config linted the *whole* monorepo, so
gatelock's mypy was type-checking crdt-sync. All paths are now root-relative,
each config is scoped to its own subproject, and the pytest hook goes through
a shared `scripts/run_subproject_tests.sh` that supplies the missing `cd` and
fails loudly if the subproject is gone.
Scoping via `files:` has one sharp edge -- rename the directory and the regex
matches nothing, so every hook passes on zero files, green and useless. An
`always_run` scope-guard hook turns that silent pass into a failure.
bandit 1.7.10 threw inside its AST visitor on Python 3.14 and *skipped* every
file while still reporting zero issues; 1.9.4 actually scans. Codespell was
also flagging a real typo the noise had buried.
Housekeeping the above turned up: `gatelock/.github/` and `crdt-sync/.github/`
were dead -- GitHub only reads the root `.github/workflows`, which already has
all four jobs -- and the two subproject `.gitignore`s were byte-identical to
each other and subsumed by the new root one.
