📝 SummarySummary by CodeRabbit
WalkthroughThe PR separates transcript transport from generic state updates. It adds task-scoped sequencing, chunked snapshots, incremental message delivery, webview resynchronization, focused-task synchronization, and related provider, task, context, and test coverage. ChangesTranscript synchronization
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change replaces full transcript state transfer with sequenced snapshots and deltas to reduce long-running webview memory pressure. Remaining risks could cause stale, missing, or inconsistent transcript content during task replacement, recovery, rewinds, or pending-action resume, so these issues should be resolved or explicitly accepted before merge.

…ider and ExtensionStateContext - Added tests for posting snapshots and handling updates in Task.spec.ts to ensure proper functionality. - Enhanced ClineProvider to manage state and message posting for CLI consumers, including handling legacy updates. - Implemented timeout for transcript resync in ExtensionStateContext to prevent stale requests. - Updated tests in ExtensionStateContext.spec.ts to validate new resync logic and ensure proper handling of transcript messages. - Improved error handling and logging for message updates and snapshot processing.

Addressed both findings from the latest CodeRabbit review in e575068. The inline stale-partial-update thread has a fix explanation and is resolved. The outside-diff finding, Publish the hydrated transcript before the resume ask, is also fixed: a sequence-bumped snapshot is awaited after both histories are hydrated and pending-action reconciliation completes, before either the generic resume prompt or pending-action replay. Cancellation is checked before and after delivery. Regression coverage includes active/completed history resume, pending-action replay, delayed reads and delivery, cancellation and abandonment, failed snapshot delivery, and a missing provider reference. No standalone history write was added. Validation passed: 477 focused tests; the full workspace test run with 11,906 Vitest tests passing plus the ESLint configuration test; lifecycle model checks; repository lint and type-check hooks. CI is rerunning on the new commit. CodeRabbit chat reported an organization-members-only restriction, so automated chat confirmation may require a maintainer. |

Follow-up: mutation CI found one surviving readiness-flag mutation before pending-action replay. Fixed the test gap in 05df081 by asserting that replay starts only after initialization. I verified the exact reported mutation fails on that assertion, restored the unchanged production code, and reran the task/persistence suites: 170 tests passed. Type checking and repository hooks passed. The follow-up is test-only; both CodeRabbit fixes remain in e575068. |

asserts task.isInitialized is true immediately before resumePendingTaskAction

Closes: # 630
Description
This PR completes the incremental transcript-delivery work proposed in #630 and builds on the state-push throttling from #1078.
Throttling reduced how often large task state was sent, but every update and hydration could still serialize and transfer the complete transcript. For long-running tasks, that payload remains large enough to exhaust the webview renderer and produce a gray screen.
The implementation introduces a dedicated, task-scoped transcript transport:
clineMessagesarray.The steady-state payload is now O(1) per append/update rather than O(N) in transcript length. Full recovery remains available, but it is transferred in bounded chunks and applied only after the complete snapshot has been validated.
This aligns with Zoo Code's Reliability First roadmap goal by keeping long-running chats responsive and making transcript synchronization deterministic and self-healing across webview reloads and task switches.
