• LLM Model: GPT-5.6 Sol

Summary:
Implemented deterministic desktop pairing deadline settlement.

Key changes:

• Added an injectable monotonic pairing clock in desktopPairing.ts.
• Added explicit overall-timeout classification so deadline-clamped polls return PAIRING_EXPIRED, while header/body and ordinary request timeouts remain unchanged.
• Updated desktopPairing.test.ts with deterministic microtask and next-task late-response tests under simulated scheduler delay.
• Tests use a fully valid token response, ensuring it can never be accepted after expiry.

Validation completed:

• Client typecheck passed.
• Client build passed.
• Full client suite passed: 51 tests.
• Focused deterministic deadline tests passed.

Overall Evaluation

This PR correctly makes desktop pairing expiry deterministic when the transport timeout reaches the pairing deadline before the lifetime timer runs. It is ready to merge.

✅ Boundary-specific classification — pairingProtocol.ts reclassifies only the overall timeout; earlier header and body timeouts retain their transport-timeout behavior.

✅ Late responses remain unusable — desktopPairing.ts marks the pairing terminal before propagating the expiry, and the transport continues owning late promise settlement and response cancellation.

✅ Deterministic regression coverage — Tests cover valid token responses settling in both a microtask and a subsequent task after the simulated deadline.

Merge blockers

No merge blockers.

Suggestions

These are optional follow-ups and are not sent to /fix.

S1: 🟢 Cover early transport timeouts

A focused completeDesktopPairing test could verify that header or body timeouts occurring strictly before the pairing deadline remain kind === 'timeout'. The phase check in packages/client/src/pairingProtocol.ts already implements this correctly, so this would be optional defense against future regression rather than required work.

Score

The implementation is narrowly scoped, internally consistent, well tested for the reported race, and all authoritative checks pass.

Score: 9/10

Overall Evaluation

The PR correctly makes desktop pairing expiry deterministic by combining wall-clock and monotonic deadlines and reclassifying only deadline-clamped transport timeouts. It is ready to merge once the four pending checks complete successfully; no current check is failing.

✅ Deadline-safe settlement — completeDesktopPairing verifies remaining lifetime after each asynchronous boundary, preventing late provisional credentials from being accepted.

✅ Narrow timeout classification — pairingProtocol.ts applies the custom error only to the overall timeout; header, body, cancellation, and caller-abort behavior retain their existing classifications.

✅ Deterministic regression coverage — The tests exercise both microtask and next-task late responses with independent controlled clocks and a fully valid provisional response.

Merge blockers

No merge blockers.

Suggestions

These are optional follow-ups and are not sent to /fix.

S1: 🟢 Add transport-level classification tests

A focused pairingTransport.test.ts case could pass overallTimeoutError and explicitly verify that only the overall boundary uses it while header and body deadlines still produce ordinary timeout errors. The implementation is already narrowly conditioned and the integration tests cover the principal regression, so this is optional defense against future refactoring.

Score

The changed behavior is internally consistent, well bounded, and covered by deterministic regression tests. With no verified blocker or failing check, only completion of the pending CI jobs remains.

Score: 9/10
