Add tests for daemon vs non-daemon parity in list filters

After bd-o43 RPC integration, we need tests to verify daemon mode behaves identically to direct mode for all new filter flags.

Test coverage needed:
- Pattern matching: --title-contains, --desc-contains, --notes-contains
- Date ranges: all 6 date filter flags (created/updated/closed after/before)
- Empty/null checks: --empty-description, --no-assignee, --no-labels
- Priority ranges: --priority-min, --priority-max
- Status normalization: --status all vs no status flag
- Date parsing: YYYY-MM-DD, RFC3339, and error cases
- Backward compat: deprecated --label flag still works

Oracle review findings (bd-o43):
- Date parsing should support multiple formats
- Status 'all' should be treated as unset
- NoLabels field was missing from RPC protocol
- Error messages should be clear and actionable

Test approach:
- Create RPC integration tests in internal/rpc/server_issues_epics_test.go
- Compare daemon client.List() vs direct store.SearchIssues() for same filters
- Verify error messages match between modes
- Test with real daemon instance, not just unit tests

bd repair command: fix orphaned foreign key refs


bd ready resolves external dependencies

Extend bd ready to check external blocked_by references:

1. Parse external:<project>:<capability> from blocked_by
2. Look up project path from external_projects config
3. Check if target project has provides:<capability> label on a closed issue
4. If not satisfied, issue is blocked

Example output:
```bash
bd ready
# gt-xyz: blocked by external:beads:mol-run-assignee (not provided)
# gt-abc: ready
```

Depends on: bd-om4a (external: prefix), bd-66w1 (config)

Part of cross-project dependency system.

Change default JSONL filename from beads.jsonl back to issues.jsonl throughout codebase


Create multi-agent race condition test

Automated test that runs 2+ agents simultaneously to verify collision prevention.

Acceptance Criteria:
- Script spawns 2 agents in parallel
- Both try to claim same issue
- Only one succeeds (via reservation)
- Other agent skips to different work
- Verify in JSONL that no duplicate claims
- Test with Agent Mail enabled/disabled

File: tests/integration/test_agent_race.py

Success Metric: Zero duplicate claims with Agent Mail, collisions without it


Daemons don't exit when parent process dies, causing accumulation and race conditions

Multiple daemon processes accumulate over time because daemons don't automatically stop when their parent process (e.g., coding agent) is killed. This causes:

1. Race conditions: 8+ daemons watching same .beads/beads.db, each with own 30s debounce timer
2. Git conflicts: Multiple daemons racing to commit/push .beads/issues.jsonl
3. Resource waste: Orphaned daemons from sessions days/hours old still running

Example: User had 8 daemons from multiple sessions (12:37AM, 7:20PM, 7:22PM, 7:47PM, 9:19PM yesterday + 9:54AM, 10:55AM today).

Solutions to consider:
1. Track parent PID and exit when parent dies
2. Use single global daemon instead of per-session
3. Document manual cleanup: pkill -f "bd daemon"
4. Add daemon lifecycle management (auto-cleanup of stale daemons)

Implementation complete:

1. Added ParentPID field to DaemonLockInfo struct (stored in daemon.lock JSON)
2. Daemon now tracks parent PID via os.Getppid() at startup
3. Both event loops (polling and event-driven) check parent process every 10 seconds
4. Daemon gracefully exits if parent process dies (detected via isProcessRunning check)
5. Handles edge cases:
   - ParentPID=0: Older daemons without tracking (ignored)
   - ParentPID=1: Adopted by init means parent died (exits)
   - Otherwise checks if parent process is still running

The fix prevents daemon accumulation by ensuring orphaned daemons automatically exit within 10 seconds of parent death.


Fix goroutine leak in daemon restart

Fire-and-forget goroutine in daemon restart leaks on every restart.

Location: cmd/bd/daemons.go:251

Problem:
go func() { _ = daemonCmd.Wait() }()

- Spawns goroutine without timeout or cancellation
- If daemon command never completes, goroutine leaks forever
- Each daemon restart leaks one more goroutine

Solution: Add timeout and cleanup:
go func() {
    done := make(chan struct{})
    go func() {
        _ = daemonCmd.Wait()
        close(done)
    }()

    select {
    case <-done:
        // Exited normally
    case <-time.After(10 * time.Second):
        // Timeout - daemon should have forked by now
        _ = daemonCmd.Process.Kill()
    }
}()

Impact: Goroutine leak on every daemon restart

Effort: 2 hours


GH#516: Automate 'landing the plane' setup in AGENTS.md

bd init or /beads:init should auto-add landing-the-plane instructions to AGENTS.md (and @AGENTS.md for web Claude). Reduces manual setup. See: https://github.com/steveyegge/beads/issues/516


Add --parent flag to bd onboard output

bd onboard didn't document --parent flag for epic subtasks, causing AI agents to guess wrong syntax. Added --parent example and CLI help section pointing to bd <cmd> --help.

Fixes: https://github.com/steveyegge/beads/issues/402


Deferred HOP schema additions (P2/P3)

Deferred from bd-7pwh after review. Add when semantics are clearer and actually needed:

- assignee_ref: Structured EntityRef alongside string assignee
- work_type: 'mutex' vs 'open_competition' (everything is mutex in v0.1)
- crystallizes: bool for work that compounds vs evaporates (can derive from issue_type)
- cross_refs: URIs to beads in other repos (needs federation first)
- skill_vector: []float32 embeddings placeholder (YAGNI)

These can be added later without breaking changes (all optional fields).

Moved to town HQ: hq-my0dy9 (HOP-specific concerns are out of scope for beads tool)


Fix bd init spins forever creating C:\.beads outside git (GH#996)

dispatched_by: mayor

bd init on Windows spins forever trying to create C:\.beads when run outside of .git. See https://github.com/steveyegge/beads/issues/996

Fixed infinite loop in findLocalBeadsDir() and findOriginalBeadsDir() on Windows - same pattern as PR #991 fix for FindBeadsDir(). On Windows, filepath.Dir("C:\\") returns "C:\\" (not "/" or "."), so the loop condition must check if parent == dir to detect filesystem root.

Investigate incremental blocked_issues_cache updates at scale

Current blocked_issues_cache strategy does full DELETE + INSERT on every dependency/status change.

**Problem at scale:**
- 10K issues: ~50ms rebuild (acceptable)
- 100K issues: ~500ms rebuild (noticeable)
- 1M issues: multi-second rebuilds (problematic)

**Current implementation (blocked_cache.go:104-154):**
- DELETE FROM blocked_issues_cache
- INSERT with recursive CTE

**Potential optimizations:**
1. **Incremental updates:** Only add/remove affected issue IDs instead of full rebuild
2. **Dirty tracking:** Skip rebuild if cache is already valid
3. **Async rebuild:** Rebuild in background, serve stale cache briefly
4. **Partial invalidation:** Only invalidate affected subtree

**Decision needed:** Is this premature optimization? Current target is <100K issues.

**Benchmark:** Add benchmark for cache rebuild at 100K scale to measure actual impact.

## Benchmark Investigation Results (2026-01-02)

**Cache rebuild timing:**
- 10K issues: 773ms (Go benchmark), ~270ms (raw SQL)
- 20K issues: 1,298ms
- Extrapolated 100K: ~6.5 seconds

Original estimates were 15x too optimistic. Go/CGO/WAL adds ~3x overhead.

**Key insight:** Most dependency changes only affect a localized subgraph. Incremental updates could reduce 773ms to <50ms for typical ops.

**Added:** BenchmarkRebuildBlockedCache_Large/XLarge in sqlite_bench_test.go

## Incremental Update Design Sketch

**When to update cache:**
1. Add blocks dep → add blocked issue + descendants to cache
2. Remove blocks dep → check if still blocked, remove if not + propagate to descendants
3. Close issue → check dependents, remove unblocked + descendants
4. Reopen issue → add dependents + descendants back

**Key insight:** Adding to cache is simple (just insert). Removing is complex (must verify no alternate blocking path).

**Proposed approach:**
- For additions: \`INSERT OR IGNORE\` the affected subgraph (fast, O(affected_nodes))
- For removals: Rebuild only for the affected subgraph, not entire cache
- Keep full rebuild as fallback for complex cases (waits-for, conditional-blocks)

**Estimated improvement:**
- Typical add/remove: O(affected_nodes) vs O(all_issues)
- 10K DB with 1 affected node: ~5ms vs 773ms (150x faster)
- Worst case (unblock entire graph): same as now

**Implementation complexity:** Medium - need to handle transitive parent-child correctly

Run bd doctor at end of bd init to verify setup

Run bd doctor diagnostics at end of bd init (after line 398 in init.go). If issues found, warn user immediately: '⚠ Setup incomplete. Run bd doctor --fix to complete setup.' Catches configuration problems before user encounters them in normal workflow.


Support wisps in nodb mode for lightweight Gas Town rigs

Enable proper wisp support in --no-db mode to allow lightweight Gas Town rigs (including HQ/Mayor) to run without SQLite overhead.

## Motivation
Gas Town HQ and simple rigs could benefit from nodb mode's simplicity. Currently wisps don't work properly in nodb mode.

## Proposed Design

### Phase 1: Session-scoped wisps
- Memory storage already has Wisp field on Issue
- Wisps exist only for the session lifetime
- Acceptable for patrol cycles that complete within a session
- Depends on: bd-9avq (fix the leak)

### Phase 2: Optional wisp persistence
- Add `.beads/wisps.jsonl` for wisp storage (gitignored)
- Load wisps from this file on nodb startup
- Save wisps to this file on nodb exit
- Wisps persist across restarts but don't sync via git

### Phase 3: Verify mol commands
- Test mol squash, burn, bond work with memory storage
- These currently check for SQLite storage type
- May need interface-based approach instead of type assertions

## Files affected
- cmd/bd/nodb.go - wisp filtering and optional persistence
- internal/storage/memory/ - verify wisp field handling
- cmd/bd/mol_*.go - verify memory storage compatibility
- .beads/.gitignore - add wisps.jsonl
