📝 SummarySummary by CodeRabbit
WalkthroughThe PR separates transcript delivery from generic state updates. It adds task- and instance-scoped sequencing, chunked snapshots, incremental updates, resynchronization, focused-task synchronization, lifecycle integration, model checking, and CSS transition settling.

Merge Risk: 🟡 Moderate · up to This update substantially reduces webview memory growth and gray-screen risk by replacing full-transcript retransmission with sequenced, chunked deltas and snapshots, and the previously flagged issues around checkpoint resynchronization, task-instance replacement staleness, snapshot sequencing, and resumed-task transcript delivery are now addressed with supporting evidence. One narrow concurrency edge case remains: if a transcript rewind happens at the same moment an API request status is being saved, the affected task's loop can crash and require a manual restart, though this does not corrupt persisted data or affect other tasks. This is worth a follow-up fix but is not a broad-impact blocker. Caution Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional.

Nice! Had a couple implementation questions.
Review statusThanks for contributing. This comment tracks the review sequence and the next action. Current step: Address automated review findings and push fixes. After fixes are pushed and required CI passes, automated review restarts. Review-state labels are managed by this workflow; do not edit them manually. |
Preserve upstream default-profile coverage after rebasing PR Zoo-Code-Org#1360 while retaining the explicit null focused-task identity required by transcript transport. Review-thread implementation remains deferred.
Publish dedicated transcript focus without generic-state side effects; guard stale metadata, reject empty deltas, and catch telemetry refresh failures. Add provider, receiver, CLI, and transport-model regressions for PR Zoo-Code-Org#1360 review feedback.
Split exhaustive fault searches into separate tests while retaining all scenarios, bounds, and the existing timeout. Consolidate producer admission and frame dispatch without weakening instance guards. Full workspace, model, lint, type, and full-PR mutation validation passed.

CodeRabbit findings addressedPublished commit: 9e5a02f. All three requested findings are fixed, regression-tested, replied to, and resolved: coalesced recovery from orphaned snapshot frames; instance-scoped hydration helpers; corrected documentation anchors. No unresolved review threads remained at verification. Validation
Remaining gates / limitationsThe fresh CodeRabbit review is still in progress and the PR review gate remains pending. No merge was performed. The full-PR mutation job reports success because it is advisory, but its validation is INCOMPLETE: extension mutation execution exceeded 12 minutes; webview preflight generated 411 mutants versus the unchanged 400 cap. No configuration, budget, exclusion, or review policy was relaxed. See https://github.com/Zoo-Code-Org/Zoo-Code/actions/runs/35288648572 . |

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.
Reviewer focus areas:
Test Procedure
Current published head: 190b186fdbf60155f4e6272af3a1c06ecbb3369e. Published with the disclosed mutation-budget blocker; cap unchanged; not merged.
The head-specific validation/status comment is the current source of truth. Full local checks passed on byte-identical reviewed source: 12,355 Vitest tests passed / 40 skipped plus one Node test file, 10/10 fresh test tasks, 11/11 fresh type and lint tasks each, all seven models, and 32/32 fresh mutation-runner tests. No local E2E/visual run is claimed.
Overall mutation validation is blocked, not green. Fresh canonical full-PR-diff local gating against base 01c7357 generated 434 extension mutants versus the unchanged 400 cap. The final 861-test baseline passed, but extension mutation execution did not start; killed/survived/no-coverage/timeout/error counts are unavailable, not zero. Webview passed with 391 valid mutants all killed and nine pre-existing ignored; that is not an overall gate pass. No cap/configuration/exclusion was relaxed.
The four source findings are fixed and resolved independently of overall merge readiness. New-head executable CI and review acceptance are tracked separately in the status comment. GitHub generated merge result 951533e with advanced main parent ebcd1a0; do not confuse that integration result or its CI with the locally audited base/head. No merge action was performed.
Historical validation - superseded for the current head
The following retained evidence applies only to the old head; its green mutation result does not validate 190b186.
Historical validated head: f7d2abb, based on 01c7357. These are local results; remote CI status is reported by the checks on this PR.
Focused regressions cover queue invalidation while physical sends are held, exactly-once caller settlement, captured nested message contents, snapshot-before-resume ordering, immediate streaming updates, final-message ordering, timestamp-index maintenance, exact chunk payloads, and atomic timeout recovery. The final focused run passed 360 tests.
