Description

The emergency condense in handleContextWindowExceededError copied the automatic path's result handling instead of sharing it, and the copy had drifted. This PR fixes the two defects from the issue and one of the argument divergences.

condenseId on the event. The emergency condense_context event had no condenseId, so MessageManager's id-based rewind cleanup could never remove the emergency summary. Deleting the condense row cut the history after the summary (summary at last message + 1, row emitted later), which left the summary in place.
Errors surfaced. An error returned by manageContext was dropped. It now shows as condense_context_error, as on the automatic path.
Shared reporter. Both paths now report through one reportContextManagementResult helper (error row, then the condense event or the truncation row), so the fields can't drift apart again. For the automatic path this is a pure move with no behaviour change.
Same condense settings (divergence 3). The emergency manageContext call now also passes the custom CONDENSE prompt, filesReadByRoo, cwd, and rooIgnoreController, so a recovery summary is built like an automatic one.

The manual condenseContext() path is unchanged. It calls summarizeConversation directly, returns early on error, and already emitted condenseId and the error row.

Not included: divergence 4, where a profile threshold can override the forced 75% during recovery. It changes recovery behaviour, so it belongs in a separate follow-up (Open question 2 in the issue).

Test Procedure

New regression tests:

Task.spec.ts → emergency condense reporting (#1769). These call the real handleContextWindowExceededError, not a mock:
- A successful condense emits contextCondense.condenseId equal to the summary's id, and summarizes with the custom prompt and cwd.
- A failed condense emits condense_context_error, followed by the fallback sliding_window_truncation row.
- Both tests fail against the original Task.ts.
message-manager/index.spec.ts: deleting the emergency condense row removes the summary when the event carries a condenseId. A second case shows the summary survives when the id is missing, which was the pre-fix behaviour.

Commands:

cd src
npx vitest run core/task/__tests__/Task.spec.ts core/message-manager core/condense core/context-management
pnpm exec eslint --max-warnings=0 core/task/Task.ts core/task/__tests__/Task.spec.ts core/message-manager/index.spec.ts

Results: 378 tests passed; type checking and ESLint passed (also via the commit hook). ESLint suppression counts are unchanged.

Additional Notes

Follow-up candidate from the issue's open questions: let recovery take precedence over profileThresholds (an empty threshold map on the emergency call, or a forceThreshold flag on manageContext). With a profile threshold of 95%, today's emergency call can return the history unchanged with no event at all.

🤖 Generated with Claude Code

The emergency condense in handleContextWindowExceededError duplicated the automatic path's result handling and had diverged: - Its condense_context event carried no condenseId, so rewind cleanup could not remove the emergency summary; deleting the condense row cut after the summary and left it in place. - A condense error returned by manageContext was dropped instead of being shown as condense_context_error. - It ignored the custom CONDENSE prompt and did not pass filesReadByRoo, cwd, or rooIgnoreController. Both paths now report through one reportContextManagementResult helper, and the emergency call passes the same condense settings. The profile threshold overriding the forced 75% is left for a follow-up. Fixes Zoo-Code-Org#1769 Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

📝 Summary

Summary by CodeRabbit

Bug Fixes
- Improved recovery when a conversation reaches its context limit. Summaries now use the configured condensation prompt and relevant workspace context.
- Rewinding a conversation now removes the corresponding summary when its event is linked to it. If the event has no link, the summary remains.
- Context-management errors are reported before recovery falls back to truncating older context.

Task now uses shared reporting for context-management results. Emergency recovery passes task context options to manageContext. Added tests cover condensation IDs, error reporting, and rewind behavior.

Changes: Context management

Layer / File(s)	Summary
Emergency and automatic context management reporting `src/core/task/Task.ts`, `src/core/task/__tests__/Task.spec.ts`, `src/core/message-manager/index.spec.ts`	`Task` reports context-management errors, condensation events with `condenseId`, and sliding-window truncation through a shared method. Emergency requests include the custom condensing prompt, files-read context, working directory, and ignore controller. Tests cover success and failure events and verify rewind behavior for matching and missing condensation IDs.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to d712c

Emergency context condensing now reports its results consistently with automatic condensing, so rewind can clean up the summary and errors become visible. No merge-blocking risk remains. The one open suggestion strengthens a test and does not affect runtime behavior.

Explanation

Issue #1769 requirements are implemented. Task.reportContextManagementResult emits condense_context_error before the fallback truncation event, and it includes ContextManagementResult.condenseId in contextCondense. Emergency recovery uses this helper. Task.spec.ts covers the real emergency handler success and failure paths. message-manager/index.spec.ts covers removal of an emergency summary when the event carries the matching ID and the pre-fix behavior when it does not. The emergency path also passes the custom prompt, file context, cwd, and ignore controller. Profile-threshold behavior remains explicitly excluded by the PR scope.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #1769. The shared reporting helper removes duplicated automatic-path logic, and the emergency-path settings align recovery reporting with automatic condensing. The added tests directly verify emergency reporting and rewind cleanup. No unrelated product behavior or unrelated files are changed.

Full details: Security Boundaries

Explanation

No changed path meets the security failure condition. Emergency recovery now reuses getFilesReadByRooSafely and passes cwd plus rooIgnoreController to manageContext; folded-file processing forwards the controller to parseSourceCodeDefinitionsForFile, which applies validateAccess. The shared reporter only emits typed context-management results. It does not execute input or bypass approval or allowlist controls.

Full details: Persistence Integrity

Explanation

No changed persistence defect is present. Emergency recovery still awaits overwriteApiConversationHistory, and the new reportContextManagementResult awaits each say operation. say awaits addToClineMessages, which awaits saveClineMessages. API and task-message writes use safeWriteJson, which writes through temporary files and rolls back on failure. The existing handling of save return values was not changed by this PR.

Full details: Lifecycle Resource Cleanup

Explanation

No changed lifecycle path introduces a resource leak or duplicate work. The PR adds an awaited reporting helper that emits existing messages, and it preserves the existing finally cleanup for the condense spinner. The emergency path only reads file-context metadata and passes existing cancellation/disposal-owned objects into manageContext; it does not create listeners, watchers, timers, providers, or tasks. The shared helper also replaces the automatic path's equivalent reporting code without adding another invocation.

Full details: Regression Evidence

Explanation

The new emergency path forwards filesReadByRoo and rooIgnoreController to manageContext (src/core/task/Task.ts:5524,5537-5546), but the focused emergency test only verifies customCondensingPrompt and cwd (src/core/task/__tests__/Task.spec.ts:2492-2510). Lower-level manageContext tests cover forwarding when called directly, not this Task wiring. A regression could therefore drop the emergency folded-file context or ignore controller without failing the PR tests.

Resolution

Extend the emergency-condense success test to make getFilesReadByRooSafely return a non-empty file list and assert the summarizeConversation options contain that list, task.cwd, and the exact task.rooIgnoreController. Add an unset/collector-failure case if the emergency fallback is intended to preserve undefined file context.
