+# Bugfix Plan: Observer Sessions Authentication Failure
+
+## Problem Summary
+
+Observer sessions fail with "Invalid API key · Please run /login" because the `CLAUDE_CONFIG_DIR` environment variable is being set to an isolated directory (`~/.claude-mem/observer-config/`) that lacks authentication credentials.
+
+## Root Cause
+
+**File:** `src/services/worker/ProcessRegistry.ts` (lines 207-211)
+
+```typescript
+const isolatedEnv = {
+  ...spawnOptions.env,
+  CLAUDE_CONFIG_DIR: OBSERVER_CONFIG_DIR  // <-- This isolates auth credentials!
+};
+```
+
+This was added in Issue #832 to prevent observer sessions from polluting the `claude --resume` list. However, it also isolates the authentication credentials, breaking the SDK's ability to authenticate with the Anthropic API.
+
+## Evidence
+
+1. Running Claude with alternate config dir reproduces the error:
+   ```bash
+   CLAUDE_CONFIG_DIR=/tmp/test-claude claude --print "hello"
+   # Output: Invalid API key · Please run /login
+   ```
+
+2. The observer config directory exists but only has cached feature flags, no authentication:
+   - `~/.claude-mem/observer-config/.claude.json` - feature flags only
+   - No credentials copied from main `~/.claude/` directory
+
+## Solution
+
+The fix must allow authentication while still isolating session history. Claude Code stores different data types in `CLAUDE_CONFIG_DIR`:
+- Authentication credentials (needed)
+- Session history/resume list (should be isolated)
+- Feature flags and settings (can be shared or isolated)
+
+**Approach:** Do NOT override `CLAUDE_CONFIG_DIR`. Instead, find an alternative solution for Issue #832.
+
+### Alternative Approaches for Session Isolation
+
+1. **Use `--no-resume` flag** (if SDK supports it) - Prevent observer sessions from being resumable
+2. **Accept pollution** - Observer sessions in resume list may be acceptable tradeoff
+3. **Post-hoc cleanup** - Clean up observer session entries from history after completion
+4. **SDK parameter** - Check if SDK has a session isolation option that doesn't affect auth
+
+---
+
+## Phase 0: Documentation Discovery
+
+### Objective
+Understand SDK options for session isolation without breaking authentication.
+
+### Tasks
+1. Read SDK documentation/source for:
+   - Available `query()` options
+   - Session isolation mechanisms
+   - Authentication handling
+
+2. Read Issue #832 context:
+   - What was the original problem?
+   - How bad was the pollution?
+   - Are there alternative solutions mentioned?
+
+### Verification
+- [ ] List all `query()` options available
+- [ ] Identify if `--no-resume` or equivalent exists
+- [ ] Document the tradeoffs
+
+---
+
+## Phase 1: Fix Authentication
+
+### Objective
+Remove the `CLAUDE_CONFIG_DIR` override to restore authentication.
+
+### File to Modify
+`src/services/worker/ProcessRegistry.ts`
+
+### Change
+Remove lines 207-211 that override `CLAUDE_CONFIG_DIR`:
+
+**Before:**
+```typescript
+const isolatedEnv = {
+  ...spawnOptions.env,
+  CLAUDE_CONFIG_DIR: OBSERVER_CONFIG_DIR
+};
+```
+
+**After:**
+```typescript
+const isolatedEnv = {
+  ...spawnOptions.env
+  // CLAUDE_CONFIG_DIR removed - observer sessions need access to auth credentials
+  // Session isolation addressed via [alternative approach]
+};
+```
+
+### Verification
+- [ ] Build succeeds: `npm run build`
+- [ ] Observer sessions authenticate successfully
+- [ ] Observations are saved to database
+
+---
+
+## Phase 2: Address Session Isolation (Issue #832)
+
+### Objective
+Find alternative solution to prevent observer sessions from polluting `claude --resume` list.
+
+### Options to Evaluate
+
+1. **Option A: Accept the tradeoff**
+   - Observer sessions appear in resume list but users can ignore them
+   - No code changes needed beyond Phase 1
+
+2. **Option B: Use isSynthetic flag**
+   - If SDK has a flag to mark sessions as non-resumable, use it
+   - Requires SDK documentation review
+
+3. **Option C: Post-processing cleanup**
+   - After session ends, remove observer entries from history
+   - More complex, may have race conditions
+
+### Decision Point
+After Phase 0 documentation review, choose the appropriate option.
+
+### Verification
+- [ ] Chosen approach documented
+- [ ] If code changes made, tests pass
+- [ ] Observer sessions either isolated OR tradeoff accepted
+
+---
+
+## Phase 3: Testing
+
+### Manual Tests
+1. Start a new Claude Code session with the plugin
+2. Verify observations are being saved (check logs)
+3. Check that no "Invalid API key" errors appear
+4. Verify `claude --resume` behavior (acceptable level of observer entries)
+
+### Verification Checklist
+- [ ] `npm run build` succeeds
+- [ ] Worker service starts without errors
+- [ ] Observations save to database
+- [ ] No authentication errors in logs
+- [ ] Issue #832 regression acceptable or addressed
+
+---
+
+## Anti-Patterns to Avoid
+
+1. **DO NOT** add `ANTHROPIC_API_KEY` to environment - authentication is handled by Claude Code's built-in credential management
+2. **DO NOT** copy credential files to observer config dir - credentials may be in keychain or other secure storage
+3. **DO NOT** try to "fix" authentication by adding API key loading - that creates Issue #588 (unexpected API charges)
+
+---
+
+## Files Involved
+
+| File | Purpose |
+|------|---------|
+| `src/services/worker/ProcessRegistry.ts` | Contains the problematic `CLAUDE_CONFIG_DIR` override |
+| `src/shared/paths.ts` | Defines `OBSERVER_CONFIG_DIR` constant |
+| `src/services/worker/SDKAgent.ts` | Uses `createPidCapturingSpawn` which sets the env |
+
+---
+
+## Risk Assessment
+
+**Low Risk:** Removing the `CLAUDE_CONFIG_DIR` override is a simple, targeted change.
+
+**Regression Risk (Issue #832):** Observer sessions may appear in `claude --resume` list again. This is a cosmetic issue vs. complete authentication failure, so the tradeoff favors removing the override.

+
+## Fix: Authentication failure from observer session isolation
+
+**Critical bugfix** for users who upgraded to v9.0.11.
+
+### Problem
+
+v9.0.11 introduced observer session isolation using `CLAUDE_CONFIG_DIR` override, which inadvertently broke authentication:
+
+```
+Invalid API key · Please run /login
+```
+
+This happened because Claude Code stores credentials in the config directory, and overriding it prevented access to existing auth tokens.
+
+### Solution
+
+Observer sessions now use the SDK's `cwd` option instead:
+- Sessions stored under `~/.claude-mem/observer-sessions/` project
+- Auth credentials in `~/.claude/` remain accessible
+- Observer sessions still won't pollute `claude --resume` lists
+
+### Affected Users
+
+Anyone running v9.0.11 who saw "Invalid API key" errors should upgrade immediately.

+
+## Bug Fixes
+
+### Observer Session Isolation (#837)
+Observer sessions created by claude-mem were polluting the `claude --resume` list, cluttering it 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**: Observer processes now use a dedicated config directory (`~/.claude-mem/observer-config/`) to isolate their session files from user sessions.
+
+Thanks to @Glucksberg for this fix! Fixes #832.
+
+### Stale memory_session_id Crash Prevention (#839)
+After a worker restart, stale `memory_session_id` values in the database could cause crashes when attempting to resume SDK conversations. The existing guard didn't protect against this because session data was loaded from the database.
+
+**Solution**: Clear `memory_session_id` when loading sessions from the database (not from cache). The key insight: if a session isn't in memory, any database `memory_session_id` is definitely stale.
+
+Thanks to @bigph00t for this fix! Fixes #817.

+
+## Bug Fix
+
+**Fixed path format mismatch causing folder CLAUDE.md files to show "No recent activity" (#794)** - Thanks @bigph00t!
+
+The folder-level CLAUDE.md generation was failing to find observations due to a path format mismatch between how API queries used absolute paths and how the database stored relative paths. The `isDirectChild()` function's simple prefix match always returned false in these cases.
+
+**Root cause:** PR #809 (v9.0.9) only masked this bug by skipping file creation when "no activity" was detected. Since ALL folders were affected, this prevented file creation entirely. This PR provides the actual fix.
+
+**Changes:**
+- Added new shared module `src/shared/path-utils.ts` with robust path normalization and matching utilities
+- Updated `SessionSearch.ts`, `regenerate-claude-md.ts`, and `claude-md-utils.ts` to use shared path utilities
+- Added comprehensive test coverage (61 new tests) for path matching edge cases

+## Bug Fixes
+
+### Prevent Creation of Empty CLAUDE.md Files (#809)
+
+Previously, claude-mem would create new `CLAUDE.md` files in project directories even when there was no activity to display, cluttering codebases with empty context files showing only "*No recent activity*".
+
+**What changed:** The `updateFolderClaudeMdFiles` function now checks if the formatted content contains no activity before writing. If a `CLAUDE.md` file doesn't already exist and there's nothing to show, it will be skipped entirely. Existing files will still be updated to reflect "No recent activity" if that's the current state.
+
+**Impact:** Cleaner project directories - only folders with actual activity will have `CLAUDE.md` context files created.

+   - When timeout fires at 3:00 but last message was at 2:59, `idleDuration` is 1 second, check fails
+   - Need to either remove redundant check or reset `lastActivityTime` on timeout
+
+2. **Missing Test Coverage** (High Priority)
+   - No tests for SessionQueueProcessor timeout logic
+   - Critical fix for high-impact bug (79 processes, 13.4GB swap)
+
+3. **Minor: Optional Chaining** (Low Priority)
+   - Use `onIdleTimeout?.()` instead of `if (onIdleTimeout) { onIdleTimeout() }`
+
+4. **Minor: Logging Enhancement** (Low Priority)
+   - Add timeout threshold to log message for debugging
+
+---
+
+## Phase 0: Documentation Discovery (COMPLETE)
+
+### Sources Consulted
+- PR #856 comments from claude, greptile-apps reviewers
+- `src/services/queue/SessionQueueProcessor.ts` (current implementation)
+
+### Allowed APIs
+- `waitForMessage(signal, timeoutMs)` → Promise<boolean>
+- `logger.info('SESSION', ...)` for logging
+
+### The Fix Strategy
+
+The reviewers suggest two options:
+
+**Option A**: Remove redundant check since `waitForMessage` enforces timeout
+```typescript
+if (!receivedMessage && !signal.aborted) {
+  // Timeout occurred - exit gracefully
+  const idleDuration = Date.now() - lastActivityTime;
+  logger.info('SESSION', 'Exiting queue iterator due to idle timeout', { ... });
+  onIdleTimeout?.();
+  return;
+}
+```
+
+**Option B**: Reset `lastActivityTime` on timeout to handle edge cases
+```typescript
+if (!receivedMessage && !signal.aborted) {
+  const idleDuration = Date.now() - lastActivityTime;
+  if (idleDuration >= IDLE_TIMEOUT_MS) {
+    logger.info('SESSION', 'Exiting...', { ... });
+    onIdleTimeout?.();
+    return;
+  }
+  // CRITICAL: Reset timer since we know queue is empty now
+  lastActivityTime = Date.now();
+}
+```
+
+**Decision**: Use Option B - it's defensive and handles spurious wakeups correctly.
+
+---
+
+## Phase 1: Fix Race Condition in SessionQueueProcessor
+
+### What to Implement
+Fix the idle timeout logic to reset `lastActivityTime` when timeout occurs but duration check fails.
+
+### Tasks
+1. In `createIterator()` at lines 50-62, add `lastActivityTime = Date.now()` after the duration check fails
+2. Use optional chaining for `onIdleTimeout?.()`
+3. Add timeout threshold to log message
+
+### Pattern to Follow
+```typescript
+if (!receivedMessage && !signal.aborted) {
+  const idleDuration = Date.now() - lastActivityTime;
+  if (idleDuration >= IDLE_TIMEOUT_MS) {
+    logger.info('SESSION', 'Idle timeout reached, triggering abort to kill subprocess', {
+      sessionDbId,
+      idleDurationMs: idleDuration,
+      thresholdMs: IDLE_TIMEOUT_MS
+    });
+    onIdleTimeout?.();
+    return;
+  }
+  // Reset timer on spurious wakeup - queue is empty but duration check failed
+  lastActivityTime = Date.now();
+}
+```
+
+### Verification
+```bash
+npm run build
+grep -A10 "idleDuration >= IDLE_TIMEOUT_MS" src/services/queue/SessionQueueProcessor.ts
+```
+
+---
+
+## Phase 2: Add Unit Tests for SessionQueueProcessor
+
+### What to Implement
+Create test file covering the idle timeout behavior.
+
+### Test Cases Required
+1. Iterator exits after idle timeout when no messages arrive
+2. `onIdleTimeout` callback is invoked on timeout
+3. Message arrival resets the idle timer
+4. Abort signal takes precedence over timeout
+5. Event listener cleanup happens correctly
+
+### Location
+`tests/services/queue/SessionQueueProcessor.test.ts`
+
+### Verification
+```bash
+npm run test -- SessionQueueProcessor
+```
+
+---
+
+## Phase 3: Build and Verify
+
+### Tasks
+1. Run `npm run build` - verify no TypeScript errors
+2. Run tests to ensure timeout behavior works
+3. Commit changes to fix/observer-idle-timeout branch
+4. Push to update PR #856
+
+### Verification
+```bash
+npm run build
+npm run test
+git diff --stat
+```
+
+---
+
+## Phase 4: Update PR Description
+
+### Tasks
+1. Update test plan checkboxes in PR description
+2. Add note about race condition fix
+
+---
+
+## Summary of Changes
+
+| File | Change |
+|------|--------|
+| `src/services/queue/SessionQueueProcessor.ts` | Fix race condition, optional chaining, enhanced logging |

+
+### PR #700: Windows Terminal Popup Fix
+**Status:** ⚠️ CONFLICTING
+
+| Metric | Value |
+|--------|-------|
+| Additions | 187 |
+| Deletions | 399 |
+| Files | 8 |
+| Risk | Medium |
+
+**What it does:**
+- Eliminates Windows Terminal popup by removing spawn-based daemon
+- Worker `start` command becomes daemon directly (no child spawn)
+- Removes `restart` command (users do `stop` then `start`)
+- Net simplification: -212 lines
+
+**Breaking changes:**
+- `restart` command removed
+
+**Review status:**
+- ✅ 1 APPROVAL from @volkanfirat (Jan 15, 2026)
+
+**Action needed:** Resolve conflicts, then ready to ship.
+
+---
+
+### PR #722: In-Process Worker Architecture
+**Status:** ⚠️ CONFLICTING
+
+| Metric | Value |
+|--------|-------|
+| Additions | 869 |
+| Deletions | 4,658 |
+| Files | 112 |
+| Risk | High |
+
+**What it does:**
+- Hook processes become the worker (no separate daemon spawning)
+- First hook that needs worker becomes the worker
+- Eliminates Windows spawn issues ("NO SPAWN" rule)
+- 761 tests pass
+
+**Architectural impact:** HIGH
+- Fundamentally changes worker lifecycle
+- Hook processes stay alive (they ARE the worker)
+- First hook wins port 37777, others use HTTP
+
+**Action needed:** Resolve conflicts. Consider relationship with PR #700 (both touch worker architecture).
+
+---
+
+### PR #657: Generate/Clean CLI Commands
+**Status:** ⚠️ CONFLICTING
+
+| Metric | Value |
+|--------|-------|
+| Additions | 1,184 |
+| Deletions | 5,057 |
+| Files | 104 |
+| Risk | Medium |
+
+**What it does:**
+- Adds `claude-mem generate` and `claude-mem clean` CLI commands
+- Fixes validation bugs (deleted folders recreated from stale DB)
+- Fixes Windows path handling
+- Adds automatic shell alias installation
+- Disables subdirectory CLAUDE.md files by default
+
+**Breaking changes:**
+- Default behavior change: folder CLAUDE.md now disabled by default
+
+**Action needed:** Resolve conflicts, complete Windows testing.
+
+---
+
+## Needs Attention
+
+### PR #863: Ragtime Email Investigation
+**Status:** 🔍 Research pending
+
+Research agent did not return results. Manual review needed.
+
+---
+
+### PR #464: Sleep Agent Pipeline (Contributor: @laihenyi)
+**Status:** 🔴 Too large for effective review
+
+| Metric | Value |
+|--------|-------|
+| Additions | 15,430 |
+| Deletions | 469 |
+| Files | 73 |
+| Wait time | 37+ days |
+| Risk | High |
+
+**What it does:**
+- Sleep Agent Pipeline with memory tiering
+- Supersession detection
+- Session Statistics API (`/api/session/:id/stats`)
+- StatusLine + PreCompact hooks
+- Context Generator improvements
+- Self-healing CI workflow
+
+**Concerns:**
+| Issue | Details |
+|-------|---------|
+| 🔴 Size | 15K+ lines is too large for effective review |
+| 🔴 SupersessionDetector | Single file with 1,282 additions |
+| 🟡 No tests visible | Test plan checkboxes unchecked |
+| 🟡 Self-healing CI | Auto-fix workflow could cause infinite commit loops |
+| 🟡 Serena config | Adds `.serena/` tooling |
+
+**Recommendation:**
+1. **Option A:** Request contributor split into 4-5 smaller PRs
+2. **Option B:** Allocate dedicated review time (several hours)
+3. **Option C:** Cherry-pick specific features (hooks, stats API)
+
+**Note:** Contributor has been waiting 37+ days. Deserves response either way.
+
+---
+
+## Shipping Strategy
+
+### Phase 1: Quick Wins (This Week)
+1. **Merge #856** — Ready now, fixes real user issue
+2. **Rebase #700** — Has approval, Windows fix needed
+3. **Rebase #657** — Useful CLI commands
+
+### Phase 2: Architecture (Careful Review)
+4. **Review #722** — High impact, conflicts with #700 approach?
+   - Both PRs eliminate spawning but in different ways
+   - May need to pick one approach
+
+### Phase 3: Contributor PR
+5. **Respond to #464** — Options:
+   - Ask for split
+   - Schedule dedicated review
+   - Cherry-pick subset
+
+### Phase 4: Investigation
+6. **Manual review #863** — Ragtime email feature
+
+---
+
+## Conflict Resolution Order
+
+Since multiple PRs have conflicts, suggested rebase order:
+
+1. **#856** (merge first — no conflicts)
+2. **#700** (rebase onto main after #856)
+3. **#657** (rebase onto main after #700)
+4. **#722** (rebase last — may conflict with #700 architecturally)
+
+---
+
+## Summary
+
+| Ready | Conflicts | Needs Work |
+|-------|-----------|------------|
+| 1 PR (#856) | 3 PRs (#700, #722, #657) | 2 PRs (#464, #863) |
+
+**Immediate action:** Merge #856, then rebase the conflict PRs in order.

Alex Newman	7566b8c650	fix: add idle timeout to prevent zombie observer processes (#856 ) * 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. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * 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 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * 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 Analyzed 6 PRs for shipping readiness: - #856: Ready to merge (idle timeout fix) - #700, #722, #657: Have conflicts, need rebase - #464: Contributor PR, too large (15K+ lines) - #863: Needs manual review Includes shipping strategy and conflict resolution order. * MAESTRO: Verify PR #856 test suite passes All 797 tests pass (3 skipped, 0 failures).

Alex Newman	abffce6424	fix: use cwd instead of CLAUDE_CONFIG_DIR for observer session isolation (#845 ) 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 Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-28 16:18:15 -05:00

Glucksberg	6791069bca	fix: isolate observer sessions to prevent polluting claude --resume list (#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 Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-28 13:47:29 -05:00
Alexander Knigge	3e6add90de	fix: prevent stale memory_session_id resume crash after worker restart (Issue #817 ) (#839 ) 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.

Alexander Knigge	182097ef1c	fix: resolve path format mismatch in folder CLAUDE.md generation (#794 ) (#813 ) 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.
