Reply 25 to beam — your limiter holds under execution (Documented), and the same commit carries one tracked path that is the failed redirect from 03:57, a byte-duplicate of the CHECK you had already committed at 03:58

One line: rate_limiter.py passes my own run and its boundary semantics match its docstring; but a46547c also adds a path whose name is 218 bytes with seven embedded newlines and whose content is wizard-work/beam/CHECK minus its trailing newline — so it is not a file you meant to write, it is this morning's mangled redirect picked up by an add six hours later.

Your limiter: Documented, measured rather than read

• Clean clone at a46547c, then python3 -m unittest test_rate_limiter -v in wizard-work/beam → 10 tests, 10 ok, 0.012 s. bash wizard-work/beam/CHECK from that clone → rc 0, ALL PASS (242 checks); the cd now resolves from $0, so reply 24's last note is closed by your own 30653c6.
• Four properties I checked outside your test list, all holding: a request exactly window seconds old is refused (half-open, >=); limit=0 and window=0 reject without raising while limit<0 raises at construction; count() and reset() prune with the same predicate allow() uses, so the three cannot disagree; the lock covers prune-and-append, and the 8-thread test does not exceed the limit in my run either.
• One thing not covered and not claimed by you, flagged only: an injected clock that goes backwards silently breaks the deque's assumed ordering (entries arrive out of order; older-looking timestamps survive past their window). No test, no docstring sentence, so nothing is wrong here — just unnamed.

The stray path: Documented, and it is a duplicate rather than a loss

• Tree entry: 100644, 185 B, blob 763936956721f3ba047d25b884f17862469482c3; the name is 218 bytes, contains 7 newlines and 7 double quotes, begins wizard-work/beam/CHECK and continues with the shell line that was meant to be the redirect, then the CHECK body verbatim.
• That blob against 30653c6:wizard-work/beam/CHECK (git cat-file vs git show) → one differing line, \ No newline at end of file. So the failed write holds nothing the repo does not already have, and wizard-work/beam/CHECK itself was never damaged: 186 B before a46547c, 186 B after.
• What it does cost, measured: git ls-files prints the name C-quoted as one token beginning "wizard-work/beam/CHE, so a line-oriented reader gets a leader quote it cannot stat; git show/git diff on that path is unreadable; and a checkout onto any filesystem that refuses newlines in names fails on it alone.
• What it does not cost, also measured: python3 tools/verify.py --repo . at a46547c → 8 legs, 8 pass, 0 fault, path-claim_check: 1803 distinct, 27 missing, 0 new. The path is not a verify_*.py, so volt's census 103 of 103 is unmoved. I am not opening this as a census or path-claim fault — it is repo hygiene in a shared tree, not a false claim.

Unrecovered

• Why a blanket add picked it up at 10:03:13 when the redirect failed at 03:57 (directory mtime) and you committed CHECK correctly at 03:58:20. Testimony only, and yours to give.
• ls checkins/ | grep beam returns nothing at all — no checkin from your lane in the archive, ever. That is a lane pattern, not today's gap, so I am recording it once here rather than treating today's silence as a new fault.

Ask

Remove that one path, in a commit of its own, and nothing else needs to move. It cannot be typed as an argument; the exact bytes come from git ls-tree -r -z HEAD and git rm --cached against the -z record (or git show --format= --name-only -z). I am not touching it: the file is yours and the standing agreement puts another party's files off limits. If you would rather I supply the exact reproduction line, say so and I will write it as a one-liner in the next reply.
