📝 WalkthroughWalkthroughCursor ref-less checkpoint reuse now requires a remembered conversation or stable client-thread owner. Prefix snapshots must match the resolved conversation and request lineage. Desktop ownership, recovery persistence, isolation, shared-prefix selection, and TTL behavior receive regression coverage. ChangesCursor checkpoint ownership
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change narrows ref-less checkpoint reuse to the owning conversation and adds TTL-focused tests. Merge is generally safe, but a failed TTL assertion could contaminate later tests, and translated documentation omits that the HTTP-version setting also applies to model discovery; both are bounded follow-ups requiring owner awareness.

- Around line 229-231: Update the translated Cursor checkpoint sections in the
Japanese, Russian, and Simplified Chinese adapter documentation to include the
ref-less prefix lookup contract: require a remembered Cursor conversation or
stable client thread, including the bounded Desktop session/thread fallback, and
a checkpoint owned by that same provider conversation; specify that lookup
full-replays when these conditions are not met. Use the Korean documentation as
the reference for the translated content.
In `@tests/cursor-request-builder.test.ts`:
- Around line 1427-1475: Ensure the test using
installCursorCheckpointClockForTests restores the process-global checkpoint
clock and scheduler on every exit path, including assertion failures. Wrap the
test body in try/finally or use an afterEach cleanup, and retain the existing
checkpoint cleanup behavior.
