Run #15 closed with Architecture's timeout pattern fully investigated and every explanation this codebase could produce ruled out, leaving one honest gap: no failed call's true duration had ever actually been measured. Before Run #16, that gap got closed the only way it could be — a real, uncensored measurement, taken outside the production timeout path.
What was fixed before this run
An uncensored diagnostic reconstructed Run #15's exact Architecture request — same 19 files, same 153,714 bytes, same prompt, same model — and dispatched it through the real provider with only the timeout extended. It succeeded at 53,845 milliseconds: consistent with every prior successful call, not new information about how long a slow one might take, but proof the request itself wasn't broken. Combined with three of the last four production runs failing at exactly 60 seconds and a successful-call band that left as little as 2.2 seconds of margin under that ceiling, Architecture's timeout was raised to 120 seconds — reached independently of Builder's own 120-second value, on Architecture's own evidence, not copied from it.
What happened
Scope completed normally, 39 seconds. Then something new happened that had nothing to do with provider timing at all.
A safety gate fired that had never fired once in fifteen prior runs of the identical task.
BinChicken's risk classifier flagged the run as high_risk, reason: "Touches infrastructure or
deployment configuration" — requiring re-authentication before anything else could proceed. Traced
directly against the actual persisted requirements text: Scope had written an acceptance criterion
titled "No Schema or Infrastructure Changes" — a heading that says the opposite of what it
matched for. The classifier's rule looks for "infrastructure" near a change-related word within
about thirty characters, with a short list of negation phrases ("do not," "must not," "no changes
to") meant to suppress exactly this kind of false positive. This phrasing wasn't on that list. A
side-by-side comparison against Run #14's own requirements artifact — which expressed the identical
constraint without ever using the word "infrastructure" — confirmed it: same intent, different
wording, and this time the wording landed on the one word the rule was watching for. The gate was
manually approved to observe what came next, after roughly eight minutes of being correctly held
for a human decision.
Architecture then produced the single most useful data point in this entire investigation. Its call took 61,354 milliseconds — input tokens, context, and prompt all identical to every prior run — and it simply succeeded, with 58.6 seconds of headroom left in the new 120-second budget. That duration is longer than the old 60-second ceiling that had already failed six consecutive attempts across three separate runs. This is not an inference or an argument anymore: a real, legitimate Architecture call that would have failed under the previous timeout completed cleanly under the new one. The fix wasn't a guess that happened to work out; it was sized correctly for a tail that has now actually been observed.
Security and UX both completed normally. A second, entirely ordinary governance gate — the same per-run approval that has appeared after Security in every one of the last fifteen runs, unrelated to the earlier safety gate — was decided, and Builder dispatched.
Builder's call completed cleanly again — 97,585 milliseconds, comfortably inside its own 120-second budget — and got rejected again, for the same reason as Run #14:
reason=commit_message_too_long, actualCommitMessageChars=1094, maxCommitMessageChars=500
Not a smaller overage this time — a bigger one. Two consecutive completed Builder attempts, two commit-message-length rejections, both well past the same 500-character limit.
What the evidence actually supports now
Architecture's timeout fix is confirmed, not inferred. A real call exceeded the old ceiling and succeeded under the new one. That's the cleanest possible resolution to the question this project has been chasing since Run #12.
The safety-gate false positive is fully explained, and it's the same underlying weakness this policy already had to patch once before, after Run #6 — a keyword-proximity rule whose negation-suppression list can't cover every way of phrasing "this must not happen." Nothing about BinChicken's code changed to cause it; ordinary variation in how the model phrases an identical requirement was enough to land on the one trigger word.
Builder's commit-message length is no longer a single data point. Two occurrences, two overages, both in the direction of "too long," is a real pattern worth understanding on its own terms now — not proof of exactly why yet, but no longer something that can be waved off as one unlucky generation.
The part worth not burying under the good news
The safety-confirmation dialog that asked for a decision on this run's flagged risk showed a truncated interpretation snippet with no way to open the actual requirements document it was quoting from. Understanding why the gate fired required pulling the full artifact directly from the database — not something available from the screen asking for the decision. That's a second, independent instance of the same gap this series keeps finding in its governance surfaces: they correctly know that a decision is needed, and don't yet show enough to make it well.
Where this leaves things
- The Architecture timeout question is closed — confirmed by a real call that would have failed under the old ceiling and succeeded under the new one, not just consistent with a hypothesis.
- The safety-gate false positive needs no new investigation — it's the same known-fragile rule class as Run #6's, traced to its exact cause, not a new kind of problem.
- Builder's commit-message length is the next real open question, now backed by two consistent data points instead of one.
- The safety-gate modal's missing link to the full artifact is a concrete, reproducible product gap, worth its own attention alongside the approval-gate legibility issue already flagged in earlier runs.
