* fix: add idle timeout to prevent zombie observer processes
Root cause fix for zombie observer accumulation. The SessionQueueProcessor
iterator now exits gracefully after 3 minutes of inactivity instead of
waiting forever for messages.
Changes:
- Add IDLE_TIMEOUT_MS constant (3 minutes)
- waitForMessage() now returns boolean and accepts timeout parameter
- createIterator() tracks lastActivityTime and exits on idle timeout
- Graceful exit via return (not throw) allows SDK to complete cleanly
This addresses the root cause that PR #848 worked around with pattern
matching. Observer processes now self-terminate, preventing accumulation
when session-complete hooks don't fire.

* fix: trigger abort on idle timeout to actually kill subprocess
The previous implementation only returned from the iterator on idle timeout,
but this doesn't terminate the Claude subprocess - it just stops yielding
messages. The subprocess stays alive as a zombie because:
1. Returning from createIterator() ends the generator
2. The SDK closes stdin via transport.endInput()
3. But the subprocess may not exit on stdin EOF
4. No abort signal is sent to kill it
Fix: Add onIdleTimeout callback that SessionManager uses to call
session.abortController.abort(). This sends SIGTERM to the subprocess
via the SDK's ProcessTransport abort handler.
Verified by Codex analysis of the SDK internals:
- abort() triggers ProcessTransport abort handler → SIGTERM
- transport.close() sends SIGTERM → escalates to SIGKILL after 5s
- Just closing stdin is NOT sufficient to guarantee subprocess exit

* fix: add idle timeout to prevent zombie observer processes
Also cleaned up hooks.json to remove redundant start commands.
The hook command handler now auto-starts the worker if not running,
which is how it should have been since we changed to auto-start.
This maintenance change was done manually.

* fix: resolve race condition in session queue idle timeout detection
- Reset timer on spurious wakeup when queue is empty but duration check fails
- Use optional chaining for onIdleTimeout callback
- Include threshold value in idle timeout log message for better diagnostics
- Add comprehensive unit tests for SessionQueueProcessor
Fixes PR #856 review feedback.

* feat: migrate installer to Setup hook
- Add plugin/scripts/setup.sh for one-time dependency setup
- Add Setup hook to hooks.json (triggers via claude --init)
- Remove smart-install.js from SessionStart hook
- Keep smart-install.js as manual fallback for Windows/auto-install
Setup hook handles:
- Bun detection with fallback locations
- uv detection (optional, for Chroma)
- Version marker to skip redundant installs
- Clear error messages with install instructions
* feat: add np for one-command npm releases
- Add np as dev dependency
- Add release, release:patch, release:minor, release:major scripts
- Add prepublishOnly hook to run build before publish
- Configure np (no yarn, include all contents, run tests)
* fix: reduce PostToolUse hook timeout to 30s
PostToolUse runs on every tool call, 120s was excessive and could cause
hangs. Reduced to 30s for responsive behavior.
* docs: add PR shipping report

The previous approach (PR #837) set CLAUDE_CONFIG_DIR to isolate observer
sessions from `claude --resume`. However, this broke authentication because
Claude Code stores credentials in the config directory.
This fix uses the SDK's `cwd` option instead:
- Observer sessions run with cwd=~/.claude-mem/observer-sessions/
- Project name = path.basename(cwd) = "observer-sessions"
- Sessions won't appear when running `claude --resume` from actual projects
- Authentication works because ~/.claude/ config is preserved
Changes:
- ProcessRegistry.ts: Remove CLAUDE_CONFIG_DIR override from spawn
- SDKAgent.ts: Add cwd option to query() pointing to observer dir
- paths.ts: Rename OBSERVER_CONFIG_DIR to OBSERVER_SESSIONS_DIR
Fixes regression from #837

Observer sessions created by claude-mem were appearing in the main Claude Code
session picker (`claude --resume`), cluttering the list with internal plugin
sessions that users never intend to resume.
In one user's case: 74 observer sessions out of ~220 total (34% noise).
## Solution
Set `CLAUDE_CONFIG_DIR` to `~/.claude-mem/observer-config/` when spawning
observer Claude processes. This stores observer session files in a separate
location, isolating them from user sessions.
## Changes
1. Added `OBSERVER_CONFIG_DIR` to paths.ts
2. Modified `createPidCapturingSpawn()` in ProcessRegistry.ts to inject
`CLAUDE_CONFIG_DIR` environment variable
Observer sessions now write their `.jsonl` files to:
`~/.claude-mem/observer-config/projects/*/`
Instead of the user's:
`~/.claude/projects/*/`
Fixes#832

When the worker restarts, the SDK context is lost but the database still contains
memory_session_id values from the previous worker instance. The existing guard
(lastPromptNumber > 1) doesn't protect against this because lastPromptNumber is
also loaded from the database.
This fix:
- Clears memory_session_id when initializing a session from DB (not from cache)
- Adds warning log when discarding stale session IDs
- Lets SDK agent capture fresh memory_session_id on first response
The key insight: if a session is not in memory, we're in a new worker instance,
and any database memory_session_id is definitely stale.
Fixes#817

The isDirectChild() function failed to match files when the API used
absolute paths (/Users/x/project/app/api) but the database stored
relative paths (app/api/router.py). This caused all folder CLAUDE.md
files to incorrectly show "No recent activity".
Changes:
- Create shared path-utils module with proper path normalization
- Implement suffix matching strategy for mixed path formats
- Update SessionSearch.ts to use shared utilities
- Update regenerate-claude-md.ts to use shared utilities (was using
outdated broken logic)
- Prevent spurious directory creation from malformed paths
- Add comprehensive test coverage for path matching edge cases
This is the proper fix for #794, replacing PR #809 which only masked
the bug by skipping file creation when "no activity" was shown.

* Fix zombie process accumulation (Issue #737)
Problem: Claude haiku subprocesses spawned by the SDK weren't terminating
properly, causing zombie process accumulation (user reported 155 processes
consuming 51GB RAM).
Root causes:
1. SDK's SpawnedProcess interface hides subprocess PIDs
2. deleteSession() didn't verify subprocess exit
3. abort() was fire-and-forget with no confirmation
4. No mechanism to track or clean up orphaned processes
Solution:
- Add ProcessRegistry module to track spawned Claude subprocesses
- Use SDK's spawnClaudeCodeProcess option to capture PIDs via custom spawn
- Pass signal parameter to enable AbortController integration
- Wait for subprocess exit in deleteSession() with 5s timeout
- Escalate to SIGKILL if graceful exit fails
- Add orphan reaper running every 5 minutes as safety net
Files changed:
- src/services/worker/ProcessRegistry.ts (new): PID registry and reaper
- src/services/worker/SDKAgent.ts: Use custom spawn to capture PIDs
- src/services/worker/SessionManager.ts: Verify subprocess exit on delete
- src/services/worker-service.ts: Start/stop orphan reaper
Fixes#737

* fix: eliminate Windows console popups during daemon spawn and Chroma operations
Two changes to fix Windows Terminal popup issues:
1. Worker daemon spawn (ProcessManager.spawnDaemon):
- Windows: Use WMIC to spawn truly independent process without console
- WMIC creates processes that survive parent exit and have no console association
- Properly handles paths with spaces via double-quoting
- Unix: Unchanged behavior with standard detached spawn
2. PID file handling (worker-service.ts):
- Worker now writes its own PID after listen() succeeds (all platforms)
- Removes race condition where spawner wrote PID before worker was ready
- On Windows, spawner PID was useless anyway
3. Chroma vector search (ChromaSync.ts):
- Temporarily disabled on Windows to prevent MCP SDK subprocess popups
- Will be re-enabled when we migrate to persistent HTTP server architecture
- Windows users still get full observation storage, just no semantic search
Tested on Windows 11 via SSH - worker spawns without console popups,
survives parent process exit, and all lifecycle commands (start/stop/restart)
work correctly.

* fix: add YAML frontmatter to slash commands for discoverability
Commands /do and /make-plan were not appearing in Claude Code because

* refactor(worker): remove dead code from worker-service.ts
Remove ~216 lines of unreachable code:
- Delete `runInteractiveSetup` function (defined but never called)
- Remove unused imports: fs namespace, spawn, homedir, readline,
existsSync/writeFileSync/readFileSync/mkdirSync
- Clean up CursorHooksInstaller imports (keep only used exports)

* fix(worker): only enable SDK fallback when Claude is configured
Add isConfigured() method to SDKAgent that checks for ANTHROPIC_API_KEY
or claude CLI availability. Worker now only sets SDK agent as fallback
for third-party providers when credentials exist, preventing cascading
failures for users who intentionally use Gemini/OpenRouter without Claude.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* refactor(worker): remove misleading re-export indirection
Remove unnecessary re-export of updateCursorContextForProject from
worker-service.ts. ResponseProcessor now imports directly from
CursorHooksInstaller.ts where the function is defined. This eliminates
misleading indirection that suggested a circular dependency existed.

* refactor(mcp): use build-time injected version instead of hardcoded strings
Replace hardcoded '1.0.0' version strings with __DEFAULT_PACKAGE_VERSION__
constant that esbuild replaces at build time. This ensures MCP server and
client versions stay synchronized with package.json.
- worker-service.ts: MCP client version now uses packageVersion
- ChromaSync.ts: MCP client version now uses packageVersion
- mcp-server.ts: MCP server version now uses packageVersion
- Added clarifying comments for empty MCP capabilities objects

* feat: Implement cleanup and validation plans for worker-service.ts
- Added a comprehensive cleanup plan addressing 23 identified issues in worker-service.ts, focusing on safe deletions, low-risk simplifications, and medium-risk improvements.
- Created an execution plan for validating intentional patterns in worker-service.ts, detailing necessary actions and priorities.
- Generated a report on unjustified logic in worker-service.ts, categorizing issues by severity and providing recommendations for immediate and short-term actions.
- Introduced documentation for recent activity in the mem-search plugin, enhancing traceability and context for changes.
* fix(sdk): remove dangerous ANTHROPIC_API_KEY check from isConfigured
Claude Code uses CLI authentication, not direct API calls. Checking for
ANTHROPIC_API_KEY could accidentally use a user's API key (from other
projects) which costs 20x more than Claude Code's pricing.
Now only checks for claude CLI availability.

* fix(worker): remove fallback agent concept entirely
Users who choose Gemini/OpenRouter want those providers, not secret
fallback behavior. Removed setFallbackAgent calls and the unused
isConfigured() method.

* feat: move development commands to plugin distribution
Move /do, /make-plan, and /anti-pattern-czar commands from project-level
.claude/commands/ to plugin/commands/ so they are distributed with the
plugin and available to all users as /claude-mem:do, /claude-mem:make-plan,
and /claude-mem:anti-pattern-czar.

* chore: Update CLAUDE.md and package version; fix bugs and enhance tests
- Updated CLAUDE.md to reflect changes and new entries for January 2026.
- Bumped package version from 9.0.2 to 9.0.3 in package.json.
- Refactored worker-service.cjs for improved error handling and process management.
- Added new bugfix documentation for critical issues identified on January 10, 2026.
- Cleaned up integration test logs and removed outdated entries in tests/integration/CLAUDE.md.
- Updated server test documentation to reflect recent changes and removed old entries.
- Enhanced hook response patterns and added new entries in hooks/CLAUDE.md.
* fix: keep anti-pattern-czar as internal dev tool
The anti-pattern-czar command relies on scripts that only exist in
the claude-mem development repository, so it shouldn't be distributed
with the plugin. Moving it back to .claude/commands/ for internal use.

* fix(worker): add JSON status output for hook framework (#638)
Adds JSON output before all process.exit() calls in the start command
so Claude Code's hook framework can track worker startup progress.
- Add exitWithStatus() helper function
- Output {"continue":true,"suppressOutput":true,"status":"ready"|"error"}
- Maintains exit code 0 for Windows Terminal compatibility
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* test(worker): add unit tests for buildStatusOutput function
Extract buildStatusOutput() as pure function for testability and add
comprehensive unit tests validating JSON structure for hook framework.
Tests cover:
- Ready/error status variants
- Required fields (continue, suppressOutput, status)
- Optional message field inclusion logic
- Edge cases (empty strings, special characters, long messages)
- JSON serialization roundtrip
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* test(worker): add CLI output capture tests for start command
Add integration tests that spawn actual worker-service start command
and verify JSON output matches hook framework contract.
Tests:
- Valid JSON with required fields (continue, suppressOutput, status)
- JSON structure matches expected format when worker healthy
- Skipped placeholders for error scenarios requiring complex setup
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* test(worker): add Claude Code hook framework compatibility tests
Add contract tests documenting the hook framework requirements:
- Exit code 0 (Windows Terminal compatibility)
- JSON output on stdout (not stderr)
- Valid JSON structure with required fields
- Critical 'continue: true' for Claude Code to proceed
- 'suppressOutput: true' for transcript mode
These tests serve as living documentation of the hook output contract,
explaining both WHAT and WHY for each requirement.
