## Thinking Path > - Paperclip runs agents and recovers failed tasks. > - Codex ACP can report usage exhaustion as a typed terminal failure. > - The shared engine removes provider text before it stores the result. > - Codex did not use the existing terminal classifier hook, so a quota failure became a generic turn failure. > - This change classifies explicit usage exhaustion before that text is removed. > - Recovery can then use quota backoff and the supported reset clock. ## Linked Issues or Issue Description **What happened?** A Codex ACP `limit` failure with explicit usage-exhaustion text produced `acpx_turn_failed`. Recovery could schedule the ordinary short retries because the quota classification and reset time were lost. **What did you expect to happen?** Keep the failure visible and use the existing provider-quota wait. Preserve a supported reset timestamp without storing provider text. **Steps to reproduce** Return a terminal ACP session failure with category `limit` and title `You've hit your usage limit for GPT-5. Switch to another model now, or try again at 4:30 PM (America/Chicago).` The real child-process regression tests exercise both pinned ACPX versions in persistent and oneshot modes. **Paperclip version** Base commit: `32573876d4`. Related work: #13651 and #13831 provide the shared hook and Claude classification. #11854 includes quota handling as part of optional credential rotation, but reads the already-sanitized result; this patch handles the typed terminal boundary without adding rotation. #13549 reads recovery text after this boundary and cannot recover discarded provider text. #9011 concerns the Codex CLI backoff. This change leaves those other mechanisms in place. ## What Changed - Register a Codex terminal-failure classifier with the existing ACP engine hook. - Recognize explicit usage exhaustion only in a typed `limit` failure. - Reuse the Codex reset-time parser and existing provider-quota recovery fields. - Leave context, turn, rate, budget, storage-capacity, and unknown failures on their existing paths. - Test real ACP children, both dependency patches, privacy, and recovery classification. Document the boundary. ## Verification - 88 focused tests passed across Codex ACP, parsing, and server recovery classification. - An initial cross-adapter run passed 53 tests, including the existing Claude quota suite. - Removing only the classifier registration makes five new integration tests fail; restoring it passes all 19 new tests. - `pnpm -r typecheck` and `pnpm build` passed. - Full Linux CI passed on `b10d60e002`, including all unit/integration shards, browser shards, typecheck/build, runner checks, and release/package gates. - The duplicate local `pnpm test:run` reported three skill-cache failures and two runner-suite failures. It is not claimed as a full local pass. - The three skill-cache failures reproduce in a clean worktree at the unchanged base commit (3 failed, 107 passed, 3 skipped across the skills and runner files). The cache rename reports `EACCES` on macOS. - An isolated runner-suite run reports two embedded PostgreSQL startup failures before its assertions (37 tests pass). No runner source is changed; the Linux CI runner and server suites passed. - Greptile reviewed the current head at 5/5 with no actionable findings or unresolved threads. ## Risks - Explicit usage-exhaustion failures now wait for quota recovery instead of short generic retries. - Unknown wording retains the existing behavior. The generic historical terminal-limit message alone cannot establish quota exhaustion. - Reset parsing keeps the existing Codex clock formats. A missing or unsupported reset uses the existing quota backoff. - No schema, credential, UI, dependency, or deployment changes. Provider text stays in memory and is absent from results and logs. ## Model Used OpenAI GPT-6 via Codex. Exact runtime model variant and context-window size were not exposed. Used reasoning, repository inspection, editing, and local tests. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge Co-authored-by: Paperclip <noreply@paperclip.ing>
