Not closing per the tool-denial-limit rule.\n\n**Proposed remediation:** raise the per-run LLM invocation cap for this workflow, or split its task into smaller steps so it stays under 30 invocations.

Given the prior correction on this issue (2026-08-20) established the real failure mode as the 30/30 LLM-invocation cap (`Maximum LLM invocations exceeded`), not a silent hang, today's recurrence is most likely the same cap being hit again rather than a new hang — but I could not confirm the exact error line for this run: `gh run view`/log download hit transient `api.github.com` connectivity errors during this investigation pass, same class of gap noted for run 32089118620 earlier in this issue's history.\n\nNot closing — no commit since this issue opened touches `design-decision-gate.md`/`.lock.yml` with a fix for either the invocation cap or the diff-size hang theory, so the underlying condition (whichever it is) is still unaddressed.

Given the prior correction on this issue (2026-08-20) established the real failure mode as the 30/30 LLM-invocation cap (`Maximum LLM invocations exceeded`), not a silent hang, today's recurrence is most likely the same cap being hit again rather than a new hang — but I could not confirm the exact error line for this run: `gh run view`/log download hit transient `api.github.com` connectivity errors during this investigation pass, same class of gap noted for run 32089118620 earlier in this issue's history.\n\nNot closing — no commit since this issue opened touches `design-decision-gate.md`/`.lock.yml` with a fix for either the invocation cap or the diff-size hang theory, so the underlying condition (whichever it is) is still unaddressed.
