fix(marks): v0.2.2 — nine findings from the cross-frontier bug-hunt panel
`/heid-bug-hunt` on U2's diff, four arms, artifact-only. Eight findings were real against live code; a ninth was already closed by v0.2.1 and is recorded as declined. Full triage in persistent-memory.d/2026-09-22-bug-hunt-panel.md. THE LOCK LIFECYCLE (4/4 convergent, and two defects in one place) `_Locked.__exit__` unlinked `.marks.lock` on the no-op path so a booth that had never been marked was left exactly as it was found. `flock` binds to an INODE: unlinking it under a blocked waiter leaves that waiter holding an exclusive lock on a deleted file while the next writer creates a fresh lock and takes it immediately. Two processes then run the read-modify-write concurrently, the later os.replace drops the earlier one's mark, and both obeyed the protocol. The cleanup existed to protect the booth's TTL, and was failing at that too: creating or removing a directory entry bumps the DIRECTORY's mtime, which is what `_newest_mtime` seeds from. The guard's comment reasons about the lock file's own mtime and misses that the directory moved underneath it. One fix: never unlink the lock, exempt `.<name>.lock` dotfiles from `_newest_mtime`, and restore the directory's mtime after creating one. THE READ PATH'S BLAST RADIUS `_clean_text` did `(text or "").replace(...)` and `marks_for` sorts on `(created, id)`, so a stored `text` that was a dict or a `created` that was a number raised out of the read path. `list_booths` reads every booth's marks on every index load, so one hand-edited file returned 500 for `/` and `/healthz` across all 25 booths. Guarded in two layers — a named type check and a `_hydrate_safe` backstop that cannot raise — and an unreadable mark now renders as ⚠ broken rather than as an empty note. ALSO - import_legacy_asks stamped `created` at whole-second resolution, so two sidecars from the same second lost the ordering the importer had just established and re-sorted alphabetically. Microseconds, per the stated `(mtime, name)` rule. - The five mark-write routes ran a blocking flock on the event loop; they now dispatch through run_in_threadpool, asserted structurally like INV-1. - `/answer` 500'd on a non-string `notes` form value where `/note` handled it. - The inline-doc tile had a flag control and no note field. - The marks panel was suppressed on any booth carrying a links.md. - The viewer's arrow keys and Escape threw away a note being typed. CLI `booth marks` printed a traceback and exited 0 on a failed read, and `--wait` emitted a whole JSON document per poll. `booth answer --wait` read a damaged file as "not yet" and spun the full hour. Both now use real exit codes — 0 ok, 1 unanswered/timed-out, 2 no such pick, 3 unreadable — and `--wait` prints once. `marks.read_error()` lets the CLI ask what the page must not: the browser stays lenient, the machine consumer gets the truth. `scripts/booth` had no tests; it has five now, run against the real script under the system python3, which also makes them a live check on INV-1. 275 tests (253 before). Live service restarted, 25/25 booth pages verified 200. |
