Improve internal/daemon test coverage (currently 22.5%)

Daemon functionality needs better coverage:
- Auto-start behavior
- Lock file management
- Discovery mechanisms
- Connection handling
- Error recovery

Current coverage: 58.3% (improved from 22.5% as of Nov 2025)


bd doctor: per-fix confirmation mode

Add an interactive mode where users can approve/reject each fix individually rather than all-or-nothing. Currently --fix prompts once for all fixes. This would give users more control over which repairs to apply, especially useful when some fixes may have side effects.


Fix `bd sync` failure due to daemon auto-export timestamp skew

`bd sync` fails with false-positive "JSONL is newer than database" after daemon auto-export.
Root Cause: Daemon exports local changes to JSONL, updating its timestamp. `bd sync` sees JSONL.mtime > DB.mtime and assumes external changes, blocking export.
Proposed Fixes:
1. `bd sync` auto-imports if timestamp matches but content differs (or just auto-imports).
2. Content-based comparison instead of timestamp only.


BG's issue to reopen


Tests take too long - unacceptable for project size

## Problem

Running `go test ./internal/importer/... -v` takes an unacceptably long time (minutes). For a project this size, tests should complete in seconds.

## Impact

- Slows down development iteration
- AI agents waste time waiting for tests
- Blocks rapid bug fixes and validation
- Poor developer experience

## Investigation Needed

- Profile which tests are slow
- Check for unnecessary sleeps, timeouts, or integration tests
- Look for tests that could be parallelized
- Consider splitting unit vs integration tests

## Goal

Test suite for a single package should complete in <5 seconds, ideally <2 seconds.

## Optimizations Applied

1. **Added t.Parallel() to CLI tests** (13 tests) - allows concurrent execution
2. **Removed unnecessary 200ms sleep** in daemon_autoimport_test.go - Execute() forces auto-import synchronously
3. **Reduced filesystem settle wait** from 100ms → 50ms on non-Windows platforms
4. **Optimized debouncer test sleeps** (9 reductions):
   - Before debounce waits: 30ms → 20ms, 20ms → 10ms
   - After debounce waits: 40ms → 35ms, 30ms → 35ms, etc.
   - Thread safety test: 100ms → 70ms
   - Sequential cycles: 50ms → 40ms (3x)
   - Cancel tests: 70-80ms → 60ms

## Results

### cmd/bd package (main improvement target):
- **Before**: 5+ minutes (timeout)
- **After**: ~18-20 seconds
- **Speedup**: ~15-18x faster

### internal/importer package:
- **After**: <1 second (0.9s)

### Full test suite (with `-short` flag):
- Most packages complete in <2s
- Total runtime constrained by sequential integration tests

## Known Issues

- TestConcurrentExternalRefImports hangs due to :memory: connection pool issue (bd-b121)
- Some sync_branch tests may need sequential execution (git worktree conflicts)

Add t.Parallel() to slow hash multiclone tests

Add t.Parallel() to TestHashIDs_MultiCloneConverge and TestHashIDs_IdenticalContentDedup so they run concurrently.

Expected savings: ~10 seconds (from 20s to ~11s)

Implementation:
- Add t.Parallel() call at start of each test function
- Verify tests don't share resources that would cause conflicts
- Run tests to confirm they work in parallel

File: beads_hash_multiclone_test.go:34, :101


Add warning when staleness check errors

## Problem

When ensureDatabaseFresh() calls CheckStaleness() and it errors (corrupted metadata, permission issues, etc.), we silently proceed with potentially stale data.

**Location:** cmd/bd/staleness.go:27-32

**Scenarios:**
- Corrupted metadata table
- Database locked by another process
- Permission issues reading JSONL file
- Invalid last_import_time format in DB

## Current Code

```go
isStale, err := autoimport.CheckStaleness(ctx, store, dbPath)
if err \!= nil {
    // If we can't determine staleness, allow operation to proceed
    // (better to show potentially stale data than block user)
    return nil
}
```

## Fix

```go
isStale, err := autoimport.CheckStaleness(ctx, store, dbPath)
if err \!= nil {
    fmt.Fprintf(os.Stderr, "Warning: Could not verify database freshness: %v\n", err)
    fmt.Fprintf(os.Stderr, "Proceeding anyway. Data may be stale.\n\n")
    return nil
}
```

## Impact
Medium - users should know when staleness check fails

## Effort
Easy - 5 minutes


Implement fs bridge layer for WASM (Go syscall/js to Node.js fs)

Go's os package in WASM returns 'not implemented on js' for mkdir and other file operations. Need to create a bridge layer that:

1. Detects WASM environment (GOOS=js)
2. Uses syscall/js to call Node.js fs module functions
3. Implements wrappers for:
   - os.MkdirAll
   - os.ReadFile / os.WriteFile
   - os.Open / os.Create
   - os.Stat / os.Lstat
   - filepath operations

Approach:
- Create internal/wasm/fs_bridge.go with //go:build js && wasm
- Export Node.js fs functions to Go using global.readFileSync, global.writeFileSync, etc.
- Wrap in Go API that matches os package signatures
- Update beads.go and storage layer to use bridge when in WASM

This unblocks bd-4462 (basic WASM testing) and [deleted:bd-5bbf] (feature parity testing).


Add tests for merge driver auto-config in bd init

Add comprehensive tests for the merge driver auto-configuration functionality in `bd init`.

**Test cases needed:**
- Auto-install in quiet mode
- Skip with --skip-merge-driver flag
- Detect already-installed merge driver
- Append to existing .gitattributes
- Interactive prompt behavior (if feasible)

**File:** `cmd/bd/init_test.go`


Configure database connection pool limits for daemon mode

Database connection pool not configured for file-based databases when running in daemon mode.

Location: internal/storage/sqlite/sqlite.go:108-116

Problem:
- Daemon is a long-running server handling concurrent RPC requests
- Multiple CLI commands hit same daemon simultaneously
- Go default: unlimited connections (MaxOpenConns=0)
- SQLite IMMEDIATE transactions serialize on write lock
- Can have 100+ goroutines blocked waiting, each holding connection
- Results in connection exhaustion and 'database is locked' errors

Current code only limits in-memory DBs:
if isInMemory {
    db.SetMaxOpenConns(1)
    db.SetMaxIdleConns(1)
}
// File DBs: UNLIMITED connections!

Fix:
if !isInMemory {
    maxConns := runtime.NumCPU() + 1  // 1 writer + N readers
    db.SetMaxOpenConns(maxConns)
    db.SetMaxIdleConns(2)
    db.SetConnMaxLifetime(0)
}

Impact: 'database is locked' errors under concurrent load in daemon mode

Note: NOT an issue for direct CLI usage (each process isolated). Only affects daemon mode where multiple CLI commands share one database pool.

Effort: 1 hour


Add transaction helper to replace manual COMMIT/ROLLBACK

Create tx.go with withTx helper that handles transaction lifecycle. Replace manual transaction blocks in create/insert/update paths.

Refactoring complete:
- Created withTx() helper in util.go
- Added ExecInTransaction() as deprecated wrapper for backward compatibility
- Refactored all manual transaction blocks to use withTx():
  - events.go: AddComment
  - dirty.go: MarkIssuesDirty, ClearDirtyIssuesByID
  - labels.go: executeLabelOperation
  - dependencies.go: AddDependency, RemoveDependency
  - compact.go: ApplyCompaction
- All tests pass successfully


Doctor: exclude merge artifacts from 'multiple JSONL' warning

## Problem
`bd doctor` warns about 'Multiple JSONL files found' when merge artifact files exist:
```
JSONL Files: Multiple JSONL files found: beads.base.jsonl, beads.left.jsonl, issues.jsonl ⚠
```

This is confusing because these aren't real issue JSONL files - they're temporary snapshots for deletion tracking.

## Fix
Exclude known merge artifact patterns from the multiple-JSONL warning:

```go
// In doctor JSONL check
skipPatterns := map[string]bool{
    "beads.base.jsonl": true,
    "beads.left.jsonl": true,
    "beads.right.jsonl": true,
}
```

## Files

Create architecture decision record (ADR)

Document why we chose Agent Mail, alternatives considered, and tradeoffs.

Acceptance Criteria:
- Problem statement (git traffic, no locks)
- Alternatives considered (custom RPC, Redis, etc.)
- Why Agent Mail fits Beads
- Integration principles (optional, graceful degradation)
- Future considerations

File: docs/adr/002-agent-mail-integration.md


Investigate why test issues persist in database

Test issues (bd-0do3, bd-cjxp, bd-phr2, etc.) keep appearing in ready/list output, cluttering real work. These appear to be leftover test data from test runs.

Need to investigate:
1. Why are test issues not being cleaned up after tests?
2. Are tests creating issues in the main database instead of test databases?
3. Should we add better test isolation or cleanup hooks?
4. Can we add a label/prefix to distinguish test issues from real issues?

These test issues have characteristics:
- Empty descriptions
- Generic titles like "Test issue 0", "Bug P0", "Issue to reopen with reason"
- Created around 2025-11-07 19:00-19:07
- Some assigned to test users like "alice", "bob", "testuser"

## Root Cause Analysis

**Problem**: Python MCP integration tests created test issues in production `.beads/beads.db` instead of isolated test databases.

**Evidence**:
- 29 test issues created on Nov 7, 2025 at 19:00-19:07
- Patterns: "Bug P0", "Test issue X", assignees "alice"/"bob"/"testuser"
- Git commit 0e8936b shows test issues committed to .beads/beads.jsonl
- Tests were being fixed for workspace isolation around the same time

**Why It Happened**:
1. Before commit 0e8936b, `test_client_lazy_initialization()` didn't set `BEADS_WORKING_DIR`
2. Tests fell back to discovering `.beads/` in the project root directory
3. Auto-sync committed test issues to production database

**Resolution**:
1. ✅ Closed 29 test pollution issues (bd-0do3, bd-cjxp, etc.)
2. ✅ Added `failIfProductionDatabase()` guard in Go test helpers
3. ✅ Added production pollution checks in RPC test setup
4. ✅ Created `conftest.py` with pytest safety checks for Python tests
5. ✅ Added `BEADS_TEST_MODE` env var to mark test execution
6. ✅ Tests now fail fast if they detect production database usage

**Prevention**:
- All test helper functions now verify database paths are in temp directories
- Python tests fail immediately if BEADS_DB points to production
- BEADS_TEST_MODE flag helps identify test vs production execution
- Clear error messages guide developers to use proper test isolation

**Files Modified**:
- cmd/bd/test_helpers_test.go - Added failIfProductionDatabase()
- internal/rpc/rpc_test.go - Added temp directory verification
- integrations/beads-mcp/tests/conftest.py - New file with pytest safeguards


Deletion propagation via deletions manifest

## Problem

When `bd cleanup -f` or `bd delete` removes issues in one clone, those deletions don't propagate to other clones. The import logic only creates/updates, never deletes. This causes "resurrection" where deleted issues reappear.

## Root Cause

Import sees DB issues not in JSONL and assumes they're "local unpushed work" rather than "intentionally deleted upstream."

## Solution: Deletions Manifest

Add `.beads/deletions.jsonl` - an append-only log of deleted issue IDs with metadata.

### Format
```jsonl
{"id":"bd-xxx","ts":"2025-11-25T10:00:00Z","by":"stevey"}
{"id":"bd-yyy","ts":"2025-11-25T10:05:00Z","by":"claude","reason":"duplicate of bd-zzz"}
```

### Fields
- `id`: Issue ID (required)
- `ts`: ISO 8601 UTC timestamp (required)
- `by`: Actor who deleted (required)
- `reason`: Optional context ("cleanup", "duplicate of X", etc.)

### Import Logic
```
For each DB issue not in JSONL:
  1. Check deletions manifest → if found, delete from DB
  2. Fallback: check git history → if found, delete + backfill manifest
  3. Neither → keep (local unpushed work)
```

### Conflict Resolution
Simultaneous deletions from multiple clones are handled naturally:
- Append-only design means both clones append their deletion records
- On merge, file contains duplicate entries (same ID, different timestamps)
- `LoadDeletions` deduplicates by ID (keeps any/first entry)
- Result: deletion propagates correctly, duplicates are harmless

### Pruning Policy
- Default retention: 7 days (configurable via `deletions.retention_days`)
- Auto-compact during `bd sync` is **opt-in** (disabled by default)
- Hard cap: `deletions.max_entries` (default 50000)
- Git fallback handles pruned entries (self-healing)

### Self-Healing
When git fallback catches a resurrection (pruned entry), it backfills the manifest. One-time git scan cost, then fast again.

### Size Estimates
- ~80 bytes/entry
- 7-day retention with 100 deletions/day = ~56KB
- Git compressed: ~10KB

## Benefits
- ✅ Deletions propagate across clones
- ✅ O(1) lookup (no git scan in normal case)
- ✅ Works in shallow clones
- ✅ Survives history rewrite
- ✅ Audit trail (who deleted what when)
- ✅ Self-healing via git fallback
- ✅ Bounded size via time-based pruning

Jira export script (jsonl2jira.py)

Create a Python script to push beads issues to Jira.

**Requires**: Jira import script to be complete first (need external_ref matching logic working)

**Features needed**:
- Create new Jira issues from beads issues without external_ref
- Update existing Jira issues matched by external_ref
- Map beads fields back to Jira fields
- Handle Jira workflow transitions (status changes may need transitions)
- Support custom field mapping for design/acceptance_criteria/notes

**Challenges**:
- Jira status changes often require workflow transitions, not direct updates
- Need to discover valid transitions via API
- Custom fields vary by Jira instance

**Usage**:
```bash
bd export | python jsonl2jira.py --create-only  # Only create, don't update
bd export | python jsonl2jira.py                 # Create and update
```

**After creation**: Sets external_ref on beads issue to link back


Add circular dependency detection to bd doctor

Added cycle detection as Check #10 in bd doctor command. Uses same recursive CTE query as DetectCycles() to find circular dependencies. Reports error status with count and fix suggestion if cycles found.


Test dependency child


Create Python adapter library

Create beads_mail_adapter.py library that wraps Agent Mail HTTP calls with health checks and graceful degradation.

Acceptance Criteria:
- AgentMailAdapter class with health check on init
- enabled flag auto-disables if server unreachable
- All methods wrapped in try/catch (non-blocking failures)
- Methods: reserve_issue(), release_issue(), notify(), check_inbox()
- Environment-based configuration (AGENT_MAIL_URL, AGENT_MAIL_TOKEN)
- Unit tests for enabled/disabled modes

File: lib/beads_mail_adapter.py


Document Claude Code for Web SessionStart hook

Create documentation for using bd in Claude Code for Web:

## Documentation locations
- README.md - Add Claude Code for Web section
- Create docs/CLAUDE_CODE_WEB.md with detailed instructions

## SessionStart hook example
```json
{
  "sessionStart": {
    "script": "npm install -g @beads/bd && bd init --quiet --prefix bd || true"
  }
}
```

## Documentation should cover
- How to configure SessionStart hook in .claude/settings.json
- Verification: Check bd is installed (bd --version)
- Basic workflow in Claude Code for Web
- Troubleshooting common issues
- Note about network restrictions and why npm approach works

## Examples
- Creating issues in web sandbox
- Syncing with git in web environment
- Using MCP server (if applicable)


Remove unreachable utility functions

Several small utility functions are unreachable:

Files to clean:
1. `internal/storage/sqlite/hash.go` - `computeIssueContentHash` (line 17)
   - Check if entire file can be deleted if only contains this function

2. `internal/config/config.go` - `FileUsed` (line 151)
   - Delete unused config helper

3. `cmd/bd/git_sync_test.go` - `verifyIssueOpen` (line 300)
   - Delete dead test helper

4. `internal/compact/haiku.go` - `HaikuClient.SummarizeTier2` (line 81)
   - Tier 2 summarization not implemented
   - Options: implement feature OR delete method

Impact: Removes 50-100 LOC depending on decisions


Fresh clone: bd should suggest 'bd init' when no database exists

On a fresh clone of a repo using beads, running `bd stats` or `bd list` gives a cryptic error:

```
Error: failed to open database: post-migration validation failed: migration invariants failed:
  - required_config_present: required config key missing: issue_prefix (database has 2 issues)
```

**Expected**: A helpful message like:
```
No database found. This appears to be a fresh clone.
Run 'bd init --prefix <prefix>' to hydrate from the committed JSONL file.
Found: .beads/beads.jsonl (38 issues)
```

**Why this matters**: The current UX is confusing for new contributors or fresh clones. The happy path should be obvious.


Sync should cleanup snapshot files after completion

## Problem
`bd sync` leaves orphaned merge artifact files (beads.base.jsonl, beads.left.jsonl) after completion, causing:
1. Doctor warnings about 'Multiple JSONL files found'
2. Confusion during debugging
3. Potential stale data issues on next sync

## Root Cause
`SnapshotManager` creates these files for 3-way merge deletion tracking but `Cleanup()` is never called after sync completes (success or failure).

## Fix
Call `SnapshotManager.Cleanup()` at end of successful sync:

```go
// sync.go after successful validation
sm := NewSnapshotManager(jsonlPath)
sm.Cleanup()
```

## Files
- cmd/bd/sync.go (add cleanup call)
- cmd/bd/snapshot_manager.go (Cleanup method exists at line 188)


Add optional post-merge git hook example for bd sync

Create example git hook that auto-runs bd sync after git pull/merge.

Add to examples/git-hooks/:
- post-merge hook that checks if .beads/issues.jsonl changed
- If changed: run `bd sync` automatically
- Make it optional/documented (not auto-installed)

Benefits:
- Zero-friction sync after git pull
- Complements auto-detection as belt-and-suspenders

Note: post-merge hook already exists for pre-commit/post-merge. Extend it to support sync.


bd doctor: add --dry-run flag to preview fixes without applying

Currently bd doctor --fix applies all fixes. Add a --dry-run flag to preview what would be fixed without making changes. This helps users understand the impact before committing to repairs.


Enhance dep tree to show full dependency graph

When running `bd dep tree <issue-id>`, the current output only shows the issue itself without its dependency relationships.

## Current Behavior

```
$ bd dep tree gt-0iqq
🌲 Dependency tree for gt-0iqq:

→ gt-0iqq: Implement Boss (global overseer) [P2] (open)
```

This doesn't show any of the dependency structure.

## Desired Behavior

Show the full dependency DAG rooted at the given issue. For example:

```
$ bd dep tree gt-0iqq
🌲 Dependency tree for gt-0iqq:

gt-0iqq: Implement Boss (global overseer) [P2] (open)
├── gt-0xh4: Boss session management [P2] (open) [READY]
│   ├── gt-le7c: Boss mail identity [P2] (open)
│   │   ├── gt-r8fe: Boss human escalation queue [P2] (open)
│   │   └── gt-vdak: Boss dispatch loop [P2] (open)
│   │       └── gt-kgy6: Boss resource management [P2] (open)
│   │           └── gt-93iv: Boss wake daemon [P2] (open)
│   └── gt-vdak: (shown above)
```

## Suggested Options

- `--direction=down|up|both` - Show dependents (what this blocks), dependencies (what blocks this), or both
- `--status=open` - Filter to only show issues with a given status
- `--depth=N` - Limit tree depth
- Handle DAG cycles gracefully (show "(shown above)" or similar for already-displayed nodes)

## Use Case

When reorganizing a set of related issues (like I just did with the Boss implementation), being able to visualize the full dependency graph helps verify the structure is correct before syncing.


Fix failing integration tests in beads-mcp

The `beads-mcp` test suite has failures in `tests/test_bd_client_integration.py` (assertion error in `test_init_creates_beads_directory`) and errors in `tests/test_worktree_separate_dbs.py` (setup failures finding database). These need to be investigated and fixed to ensure a reliable CI baseline.


Address gosec security warnings (102 issues)

Security linter warnings: file permissions (0755 should be 0750), G304 file inclusion via variable, G204 subprocess launches. Many are false positives but should be reviewed.

Investigate jujutsu VCS as potential solution for conflict-free merging

## Context
Current N-way collision resolution struggles with Git line-based merge model. When 5+ clones create issues with same ID, Git merge conflicts require manual resolution, and our collision resolver can fail during convergence rounds.

## Research Question
Could jujutsu (jj) provide better conflict handling for JSONL files?

## Jujutsu Overview
- Next-gen VCS built on libgit2
- Designed to handle conflicts as first-class citizens
- Supports conflict-free replicated data types (CRDTs) in some scenarios
- Better handling of concurrent edits
- Can work with Git repos (compatible with existing infrastructure)

## Investigation Tasks
1. JSONL Merge Behavior - How does jj handle line-by-line JSONL conflicts?
2. Integration Feasibility - Can beads use jj as backend while maintaining Git compatibility?
3. Conflict Resolution Model - Does jj conflict model map to our collision resolution?
4. Operational Transform Support - Does jj implement operational transforms?

## Deliverables
1. Technical report on jj merge algorithm for JSONL
2. Proof-of-concept: 5-clone collision test using jj instead of Git
3. Performance comparison: Git vs jj for beads workload
4. Recommendation: Adopt, experiment further, or abandon

- Unit tests for worktree management
- Unit tests for config parsing
- Integration tests: create/update/close → beads branch
- Integration test: merge beads → main
- Integration test: protected branch scenario
- Integration test: network failure recovery
- Integration test: config change handling
- Manual testing guide
- Performance testing (worktree overhead)

Test scenarios: fresh setup, issue operations, merge workflow, protected branch, error handling, migration, multiple workspaces, sparse checkout

Estimated effort: 4-5 days

Completed comprehensive test coverage. Added 4 new integration tests: config change handling, multiple concurrent clones (3-way), performance testing (avg 77ms < 150ms target), and network failure recovery. All tests pass. Coverage includes fresh setup, issue ops, error handling, multiple workspaces, sparse checkout, config changes, network failures, and performance.


Add TestNWayCollision for 5+ clones

## Overview
Add comprehensive tests for N-way (5+) collision resolution to verify the solution scales beyond 3 clones.

## Purpose
While TestThreeCloneCollision validates the basic N-way case, we need to verify:
1. Solution scales to arbitrary N
2. Performance is acceptable with more clones
3. Convergence time is bounded
4. No edge cases in larger collision groups

## Implementation Tasks

### 1. Create TestFiveCloneCollision
File: beads_twoclone_test.go (or new beads_nway_test.go)

```go
func TestFiveCloneCollision(t *testing.T) {
    // Test with 5 clones creating same ID with different content
    // Verify all 5 clones converge after sync rounds

    t.Run("SequentialSync", func(t *testing.T) {
        testNCloneCollision(t, 5, "A", "B", "C", "D", "E")
    })

    t.Run("ReverseSync", func(t *testing.T) {
        testNCloneCollision(t, 5, "E", "D", "C", "B", "A")
    })

    t.Run("RandomSync", func(t *testing.T) {
        testNCloneCollision(t, 5, "C", "A", "E", "B", "D")
    })
}
```

### 2. Implement generalized testNCloneCollision
Generalize the 3-clone test to handle arbitrary N:

```go
func testNCloneCollision(t *testing.T, numClones int, syncOrder ...string) {
    t.Helper()

    if len(syncOrder) != numClones {
        t.Fatalf("syncOrder length (%d) must match numClones (%d)",
            len(syncOrder), numClones)
    }

    tmpDir := t.TempDir()

    // Setup remote and N clones
    remoteDir := setupBareRepo(t, tmpDir)
    cloneDirs := make(map[string]string)

    for i := 0; i < numClones; i++ {
        name := string(rune('A' + i))
        cloneDirs[name] = setupClone(t, tmpDir, remoteDir, name)
    }

    // Each clone creates issue with same ID but different content
    for name, dir := range cloneDirs {
        createIssue(t, dir, fmt.Sprintf("Issue from clone %s", name))
    }

    // Sync in specified order
    for _, name := range syncOrder {
        syncClone(t, cloneDirs[name], name)
    }

    // Final pull for convergence
    for name, dir := range cloneDirs {
        finalPull(t, dir, name)
    }

    // Verify all clones have all N issues
    expectedTitles := make(map[string]bool)
    for i := 0; i < numClones; i++ {
        name := string(rune('A' + i))
        expectedTitles[fmt.Sprintf("Issue from clone %s", name)] = true
    }

    for name, dir := range cloneDirs {
        titles := getTitles(t, dir)
        if !compareTitleSets(titles, expectedTitles) {
            t.Errorf("Clone %s missing issues: expected %v, got %v",
                name, expectedTitles, titles)
        }
    }

    t.Log("✓ All", numClones, "clones converged successfully")
}
```

### 3. Add performance benchmarks
Test convergence time and memory usage:

```go
func BenchmarkNWayCollision(b *testing.B) {
    for _, n := range []int{3, 5, 10, 20} {
        b.Run(fmt.Sprintf("N=%d", n), func(b *testing.B) {
            for i := 0; i < b.N; i++ {
                // Run N-way collision and measure time
                testNCloneCollisionBench(b, n)
            }
        })
    }
}
```

### 4. Add convergence time tests
Verify bounded convergence:

```go
func TestConvergenceTime(t *testing.T) {
    // Test that convergence happens within expected rounds
    // For N clones, should converge in at most N-1 sync rounds

    for n := 3; n <= 10; n++ {
        t.Run(fmt.Sprintf("N=%d", n), func(t *testing.T) {
            rounds := measureConvergenceRounds(t, n)
            maxExpected := n - 1
            if rounds > maxExpected {
                t.Errorf("Convergence took %d rounds, expected ≤ %d",
                    rounds, maxExpected)
            }
        })
    }
}
```

### 5. Add edge case tests
Test boundary conditions:
- All N clones have identical content (dedup works)
- N-1 clones have same content, 1 differs
- All N clones have unique content
- Mix of collisions and non-collisions

## Acceptance Criteria
- TestFiveCloneCollision passes with all sync orders
- All 5 clones converge to identical content
- Performance is acceptable (< 5 seconds for 5 clones)
- Convergence time is bounded (≤ N-1 rounds)
- Edge cases handled correctly
- Benchmarks show scalability to 10+ clones

## Files to Create/Modify
- beads_twoclone_test.go or beads_nway_test.go
- Add helper functions for N-clone setup

## Testing Strategy

### Test Matrix
| N Clones | Sync Orders | Expected Result |
|----------|-------------|-----------------|
| 3        | A→B→C       | Pass            |
| 3        | C→B→A       | Pass            |
| 5        | A→B→C→D→E   | Pass            |
| 5        | E→D→C→B→A   | Pass            |
| 5        | Random      | Pass            |
| 10       | Sequential  | Pass            |

### Performance Targets
- 3 clones: < 2 seconds
- 5 clones: < 5 seconds
- 10 clones: < 15 seconds

## Dependencies
- Requires bd-cbed9619.5, bd-cbed9619.4, bd-0dcea000, bd-4d7fca8a to be completed
- TestThreeCloneCollision must pass first

## Success Metrics
- All tests pass for N ∈ {3, 5, 10}
- Convergence time scales linearly (O(N))
- Memory usage reasonable (< 100MB for 10 clones)
- No data corruption or loss in any scenario


MCP server loses workspace context after Amp restart - causes silent failures

**CRITICAL BUG**: The beads MCP server loses workspace context when Amp restarts, leading to silent failures and potential data corruption.

## Reproduction
1. Start Amp with beads MCP server configured
2. Call `mcp__beads__set_context(workspace_root="/path/to/project")`
3. Use MCP tools successfully (e.g., `mcp__beads__show`, `mcp__beads__list`)
4. Restart Amp (new thread/session)
5. Try to use MCP tools without calling `set_context` again
6. **Result**: "Not connected" or "No workspace set" errors

## Impact
- Amp agents silently fail when trying to read/update beads issues
- May attempt to create duplicate issues because they can't see existing ones
- Potential for data corruption if operating on wrong database
- Breaks multi-session workflows
- Creates confusion: CLI works (`./bd`) but MCP tools don't

## Current Workaround
Manually call `mcp__beads__set_context()` at start of every Amp session.

## Root Cause
MCP server is stateful and doesn't persist workspace context across restarts.

## Proposed Fix
**Option 1 (Best)**: Auto-detect workspace from current working directory
- Match behavior of CLI `./bd` commands
- Check for `.beads/` directory in current dir or parents
- No manual context setting needed

**Option 2**: Persist context in MCP server state file
- Save last workspace_root to `~/.config/beads/mcp_context.json`
- Restore on server startup

**Option 3**: Require explicit context in every MCP call
- Add optional `workspace_root` parameter to all MCP tools
- Fall back to saved context if not provided

Acceptance:
- MCP tools work across Amp restarts without manual set_context()
- Auto-detection matches CLI behavior (walks up from CWD)
- Clear error message when no workspace found
- set_context() still works for explicit override
- BEADS_WORKING_DIR env var support
- Integration test validates restart behavior


Fix TestMigrateHashIDs test failure

Test failure in cmd/bd/migrate_hash_ids_test.go:100 - New ID bd-09970281 for bd-1 is not a hash ID. This test is validating the hash ID migration but the generated ID doesn't match the expected format.


cmd/bd test suite is absurdly slow - 279 tests taking 8+ minutes

# Problem

The cmd/bd test suite is painfully slow:
- **279 tests** in cmd/bd alone
- Full suite takes **8+ minutes** to run
- Even with the 16 slowest integration tests now tagged with `integration` build tag, the remaining tests still take forever

This makes the development loop unusable. We can't wait 8+ minutes every time we want to run tests.

# Root Cause Analysis

## 1. Sheer Volume
279 tests is too many for a single package. Even at 0.1s per test, that's 28 seconds minimum just for cmd/bd.

## 2. Each Test Creates Full Database + Temp Directories
Every test does heavy setup:
- Creates temp directory (`t.TempDir()` or `os.MkdirTemp`)
- Initializes SQLite database
- Sets up git repo in many cases
- Creates full storage layer

Example from the tests:
```go
func setupCLITestDB(t *testing.T) string {
    tmpDir := createTempDirWithCleanup(t)
    runBDInProcess(t, tmpDir, "init", "--prefix", "test", "--quiet")
    return tmpDir
}
```

This happens 279 times!

## 3. Tests Are Not Properly Categorized
We have three types of tests mixed together:
- **Unit tests** - should be fast, test single functions
- **Integration tests** - test full workflows, need DB/git
- **End-to-end tests** - test entire CLI commands

They're all lumped together in cmd/bd, all running every time.

# What We've Already Fixed

Added `integration` build tags to 16 obviously-slow test files:
- import_profile_test.go (performance benchmarking tests)
- export_mtime_test.go (tests with time.Sleep calls)
- cli_fast_test.go (full CLI integration tests)
- delete_test.go, import_uncommitted_test.go, sync_local_only_test.go (git integration)
- And 10 more in internal/ packages

These are now excluded from the default `go test ./...` run.

# Proposed Solutions

## Option 1: Shared Test Fixtures (Quick Win)
Create a shared test database that multiple tests can use:
```go
var testDB *sqlite.SQLiteStorage
var testDBOnce sync.Once

func getSharedTestDB(t *testing.T) storage.Storage {
    testDBOnce.Do(func() {
        // Create one DB for all tests
    })
    return testDB
}
```

**Pros**: Easy to implement, immediate speedup
**Cons**: Tests become less isolated, harder to debug failures

## Option 2: Table-Driven Tests (Medium Win)
Collapse similar tests into table-driven tests:
```go
func TestCreate(t *testing.T) {
    tests := []struct{
        name string
        args []string
        want string
    }{
        {"basic issue", []string{"create", "Test"}, "created"},
        {"with description", []string{"create", "Test", "-d", "desc"}, "created"},
        // ... 50 more cases
    }

    db := setupOnce(t) // Setup once, not 50 times
    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            // test using shared db
        })
    }
}
```

**Pros**: Dramatically reduces setup overhead, tests run in parallel
**Cons**: Requires refactoring, tests share more state

## Option 3: Split cmd/bd Tests Into Packages (Big Win)
Move tests into focused packages:
- `cmd/bd/internal/clitests` - CLI integration tests (mark with integration tag)
- `cmd/bd/internal/unittests` - Fast unit tests
- Keep only essential tests in cmd/bd

**Pros**: Clean separation, easy to run just fast tests
**Cons**: Requires significant refactoring

## Option 4: Parallel Execution (Quick Win)
Add `t.Parallel()` to independent tests:
```go
func TestSomething(t *testing.T) {
    t.Parallel() // Run this test concurrently with others
    // ...
}
```

**Pros**: Easy to add, can cut time in half on multi-core machines
**Cons**: Doesn't reduce actual test work, just parallelizes it

## Option 5: In-Memory Databases (Medium Win)
Use `:memory:` SQLite databases instead of file-based:
```go
store, err := sqlite.New(ctx, ":memory:")
```

**Pros**: Faster than disk I/O, easier cleanup
**Cons**: Some tests need actual file-based DBs (export/import tests)

# Recommended Approach

**Short-term (this week)**:
1. Add `t.Parallel()` to all independent tests in cmd/bd
2. Use `:memory:` databases where possible
3. Create table-driven tests for similar test cases

**Medium-term (next sprint)**:
4. Split cmd/bd tests into focused packages
5. Mark more integration tests appropriately

**Long-term (backlog)**:
6. Consider shared test fixtures with proper isolation

# Current Status

We've tagged 16 files with `integration` build tag, but the remaining 279 tests in cmd/bd still take 8+ minutes. This issue tracks fixing the cmd/bd test performance specifically.

# Target

Get `go test ./...` (without `-short` or `-tags=integration`) down to **under 30 seconds**.

# THE REAL ROOT CAUSE (Updated Analysis)

After examining the actual test code, the problem is clear:

## Every Test Creates Its Own Database From Scratch

Look at `create_test.go`:
```go
func TestCreate_BasicIssue(t *testing.T) {
    tmpDir := t.TempDir()                          // ← Creates temp dir
    testDB := filepath.Join(tmpDir, ".beads", "beads.db")
    s := newTestStore(t, testDB)                   // ← Opens NEW SQLite connection
                                                    // ← Runs migrations
                                                    // ← Sets config
    // ... actual test (3 lines)
}

func TestCreate_WithDescription(t *testing.T) {
    tmpDir := t.TempDir()                          // ← Creates ANOTHER temp dir
    testDB := filepath.Join(tmpDir, ".beads", "beads.db")
    s := newTestStore(t, testDB)                   // ← Opens ANOTHER SQLite connection
    // ... actual test (3 lines)
}
```

**This happens 279 times!**

## These Tests Don't Need Isolation!

Most tests are just checking:
- "Can I create an issue with a title?"
- "Can I create an issue with a description?"
- "Can I add labels?"

They don't conflict with each other. They could all share ONE database!

## The Fix: Test Suites with Shared Setup

Instead of:
```go
func TestCreate_BasicIssue(t *testing.T) {
    s := newTestStore(t, t.TempDir()+"/db")  // ← Expensive!
    // test
}

func TestCreate_WithDesc(t *testing.T) {
    s := newTestStore(t, t.TempDir()+"/db")  // ← Expensive!
    // test
}
```

Do this:
```go
func TestCreate(t *testing.T) {
    // ONE setup for all subtests
    s := newTestStore(t, t.TempDir()+"/db")

    t.Run("basic_issue", func(t *testing.T) {
        t.Parallel()  // Can run concurrently - tests don't conflict
        // test using shared `s`
    })

    t.Run("with_description", func(t *testing.T) {
        t.Parallel()
        // test using shared `s`
    })

    // ... 50 more subtests, all using same DB
}
```

**Result**: 50 tests → 1 database setup instead of 50!

## Why This Works

SQLite is fine with concurrent reads and isolated transactions. These tests:
- ✅ Create different issues (no ID conflicts)
- ✅ Just read back what they created
- ✅ Don't depend on database state from other tests

They SHOULD share a database!

## Real Numbers

Current:
- 279 tests × (create dir + init SQLite + migrations) = **8 minutes**

After fix:
- 10 test suites × (create dir + init SQLite + migrations) = **30 seconds**
- 279 subtests running in parallel using those 10 DBs = **5 seconds**

**Total: ~35 seconds instead of 8 minutes!**

## Implementation Plan

1. **Group related tests** into suites (Create, List, Update, Delete, etc.)
2. **One setup per suite** instead of per test
3. **Use t.Run() for subtests** with t.Parallel()
4. **Keep tests that actually need isolation** separate (export/import tests, git operations)

This is way better than shuffling tests into folders!

## Progress Update (2025-11-21)

✅ **Completed**:
- Audited all 280 tests, created TEST_SUITE_AUDIT.md ([deleted:bd-c49])
- Refactored create_test.go to shared DB pattern ([deleted:bd-y6d])
- Proven the pattern works: 11 tests now run in 0.04s with 1 DB instead of 11

❌ **Current Reality**:
- Overall test suite: Still 8+ minutes (no meaningful change)
- Only 1 of 76 test files refactored
- Saved ~10 DB initializations out of 280

## Acceptance Criteria (REALISTIC)

This task is NOT complete until:
- [ ] All P1 files refactored (create ✅, dep, stale, comments, list, ready)
- [ ] Test suite runs in < 2 minutes
- [ ] Measured and verified actual speedup

## Next Steps

1. Refactor remaining 5 P1 files: dep_test.go, stale_test.go, comments_test.go, list_test.go, ready_test.go
2. Measure actual time improvement after each file
3. Continue with P2 files if needed to hit <2min target


CI failing on all 3/4 test jobs despite individual tests passing

CI has been broken for a day+ with mysterious test failures. Issue #173 on GitHub tracks this.

## Current Status
- **Lint job**: ✅ PASSING
- **Test (Linux)**: ❌ FAILING (exit code 1)
- **Test (Windows)**: ❌ FAILING (exit code 1)
- **Test Nix Flake**: ❌ FAILING (exit code 1)

## Key Observations
All three failing jobs show identical pattern:
- Individual test output shows PASS for every test
- Final result: `FAIL github.com/steveyegge/beads/cmd/bd`
- Exit code 1 despite no visible test failures
- Last visible test output before failure: "No Reason Issue" test (TestCloseCommand/close_without_reason)

## Investigation So Far
1. All tests appear to pass when examined individually
2. Likely causes:
   - Race detector finding data races during test cleanup (`-race` flag)
   - Panic/error occurring after main tests complete
   - Test harness issue not reporting actual failure
   - Possible regression from PR #203 (dependency_type changes)

## Recent CI Runs
- Run 19015040655 (latest): 3/4 failing
- Multiple recent commits tried to fix Windows/lint issues
- Agent on rrnewton/beads fork attempting fixes (2/4 passing there)

## Next Steps
1. Run tests locally with `-race -v` to see full output
2. Check for unreported test failures or panics
3. Examine test cleanup/teardown code
4. Review recent changes around close command tests
5. Consider if race detector is too sensitive or catching real issues

## Progress Update

### ✅ Fixed (commits 09bd4d3, 21a29bc)
1. **Daemon auto-import** - Always recompute content_hash in importer to avoid stale hashes
2. **TestScripts failures** - Added bd binary to PATH for shell subprocess tests
3. **Test infrastructure** - Added .gitignore to test repos, fixed last_import_time metadata

### ✅ CI Status (Run 19015638968)
- **Test (Linux)**: ✅ SUCCESS - All tests passing
- **Test (Windows)**: ❌ FAILURE - Pre-existing Windows test failures
- **Test Nix Flake**: ❌ FAILURE - Build fails with same test errors
- **Lint**: ❌ FAILURE - Pre-existing issue in migrate.go:647

### ❌ Remaining Issues (not related to original bd-1231)

**Windows failures:**
- TestFindDatabasePathEnvVar
- TestHashIDs_MultiCloneConverge
- TestHashIDs_IdenticalContentDedup
- TestDatabaseReinitialization (5 subtests)
- TestFindBeadsDir_NotFound
- TestMetricsSnapshot/uptime

**Lint failure:**
- cmd/bd/migrate.go:647:37: cleanupWALFiles - result 0 (error) is always nil (unparam)

**Nix failure:**
- Build fails during test phase with same test errors

### Next Steps
1. Investigate Windows-specific test failures
2. Fix linting issue in migrate.go
3. Debug Nix build test failures


Fix bd doctor --fix recursive message for deletions manifest

When running bd doctor --fix, if the deletions manifest check fails but there are no deleted issues in git history, the fix succeeds but doesn't create the file. The check then runs again and tells user to run bd doctor --fix - the same command they just ran.

Fix: Create empty deletions.jsonl when hydration finds no deletions, and recognize empty file as valid in the check.

Fixes: https://github.com/steveyegge/beads/issues/403

- Epic hierarchies (depth 4): Epic → Feature → Task → Subtask
- Cross-linked dependencies (tasks blocking across epics)
- Realistic status/priority/label distribution
- Representative assignees and temporal data

Implementation:
- Single file: internal/testutil/fixtures/fixtures.go
- No config structs, simple direct functions
- Seeded RNG for reproducibility
- Reusable by both benchmarks and tests


deletions.jsonl gets corrupted with full issue objects instead of deletion records

## Bug Description

The deletions.jsonl file was found to contain full issue objects (like issues.jsonl) instead of deletion records.

### Expected Format (DeletionRecord)
```json
{"id":"bd-xxx","timestamp":"2025-...","actor":"user","reason":"deleted"}
```

### Actual Content Found
```json
{"id":"bd-03r","title":"Document deletions manifest...","description":"...","status":"closed",...}
```

## Impact
- bd sync sanitization step reads deletions.jsonl and removes any matching IDs from issues.jsonl
- With 60 full issue objects in deletions.jsonl, ALL 60 issues were incorrectly removed during sync
- This caused complete data loss of the issue database

## Root Cause (suspected)
Something wrote issues.jsonl content to deletions.jsonl. Possible causes:
- Export writing to wrong file
- File path confusion during sync
- Race condition between export and deletion tracking

## Related Issues
- bd-0b2: --no-git-history flag (just fixed)
- bd-4pv: export outputs only 1 issue after corruption
- bd-4t7: auto-import runs during --no-auto-import

## Reproduction
Unknown - discovered during bd sync session on 2025-11-26

## Fix
Need to investigate what code path could write issue objects to deletions.jsonl

bd sync corrupts issues.jsonl in multi-clone environments

During parallel swarm operations on 2025-11-29, bd sync corrupted the issues database. Commit 93718056 purged all 80 issues from issues.jsonl.

Reproduction:
1. Multiple clones of same repo (polecat swarm)
2. Each clone runs bd sync in parallel
3. One sync overwrites others, resulting in data loss

Even in single-clone scenarios (~/src/beads), running bd sync after git pull seems to nuke the JSONL.

Workaround: Use bd import -i .beads/issues.jsonl --no-git-history instead of bd sync.

Root cause investigation needed. Options:
1. Pessimistic locking (flock)
2. Single point of merge (polecats on ephemeral branches)
3. Beads-level locking (bd sync --lock)


Add template support for issue creation

Support creating issues from predefined templates to streamline common workflows like epics, bug reports, or feature proposals.

Example usage:
  bd create --from-template epic "Phase 3 Features"
  bd create --from-template bug "Login failure"
  bd template list
  bd template create epic

Templates should include:
- Pre-filled description structure
- Suggested priority and type
- Common labels
- Design/acceptance criteria sections

Implementation notes:
- Store templates in .beads/templates/ directory
- Support YAML or JSON format
- Ship with built-in templates (epic, bug, feature)
- Allow custom project-specific templates


Investigation & Proof of Concept

Validate that MCP Agent Mail works as expected and delivers promised benefits before committing to full integration.

POC completed successfully:
✅ bd-muls: Server installed and tested
✅ bd-27xm: MCP tool execution issues resolved
✅ [deleted:bd-6hji]: File reservation collision prevention validated
✅ bd-htfk: Latency benchmarking shows 20-50x improvement
✅ bd-pmuu: ADR 002 created documenting integration decision

Results validate Agent Mail benefits:
- Collision prevention works (exclusive file reservations)
- Latency: <100ms (vs 2000-5000ms git sync)
- Lightweight deployment (<50MB memory)
- Optional/non-intrusive integration approach validated

bd resolve-conflicts - Git merge conflict resolver

Automatically resolve JSONL merge conflicts.

Modes:
- Mechanical: ID remapping (no AI)
- AI-assisted: Smart merge/keep decisions
- Interactive: Review each conflict

Handles <<<<<<< conflict markers in .beads/beads.jsonl

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.


Document CLI + hooks as recommended approach over MCP

Update documentation to position CLI + bd prime hooks as the primary recommended approach over MCP server, explaining why minimizing context matters even with large context windows (compute cost, energy, environment, latency).


Add tests for daemon lifecycle module


Add validation for duplicate external_ref in batch imports

Currently, if a batch import contains multiple issues with the same external_ref, the behavior is undefined. We should detect and handle this case.

Current behavior:
- No validation for duplicate external_ref within a batch
- Last-write-wins or non-deterministic behavior

Proposed solution:
- Detect duplicate external_ref values in incoming batch
- Fail with clear error message OR
- Merge duplicates intelligently (use newest timestamp)
- Add test case for this scenario

Related: bd-1022


Add UNIQUE constraint on external_ref column

The external_ref column should have a UNIQUE constraint to prevent multiple issues from having the same external reference. This ensures data integrity when syncing from external systems (Jira, GitHub, Linear).

Current behavior:
- Multiple issues can have the same external_ref
- GetIssueByExternalRef returns first match (non-deterministic with duplicates)

Proposed solution:
- Add UNIQUE constraint to external_ref column
- Add migration to check for and resolve existing duplicates
- Update tests to verify constraint enforcement

Related: bd-1022


Add security tests for file path validation in clean command

Test coverage gap identified by automated analysis (vc-217).

**Original Issue:** [deleted:bd-da96-baseline-lint]

In cmd/bd/clean.go:118, os.Open(gitignorePath) is flagged by gosec G304 for potential file inclusion via variable without validation.

Add tests covering:
- Path traversal attempts (../../etc/passwd)
- Absolute paths outside project directory
- Symlink following behavior
- Non-existent file handling
- Validation that only .gitignore files in valid locations are opened

This is a security-sensitive code path that needs validation to prevent unauthorized file access.

_This issue was automatically created by AI test coverage analysis._


Test graceful degradation when server unavailable

Verify that agents continue working normally when Agent Mail server is stopped or unreachable.

Acceptance Criteria:
- Agent detects server unavailable on startup
- Logs "falling back to Beads-only mode"
- All bd commands work normally
- Agent can claim issues (no reservations, like today)
- Git sync operates as normal
- No errors or crashes

Success Metric: Zero functional difference when Agent Mail unavailable


Add --body-file flag to bd create for reading descriptions from files

## Problem

Creating issues with long/complex descriptions via CLI requires shell escaping gymnastics:

```bash
# Current workaround - awkward heredoc quoting
bd create --title="..." --description="$(cat <<'EOF'
...markdown...
EOF
)"

# Often fails with quote escaping errors in eval context
# Agents resort to writing temp files then reading them
```

## Proposed Solution

Add `--body-file` and `--description-file` flags to read description from a file, matching `gh` CLI pattern.

```bash
# Natural pattern that aligns with training data
cat > /tmp/desc.md << 'EOF'
...markdown content...
EOF

bd create --title="..." --body-file=/tmp/desc.md
```

## Implementation

### 1. Add new flags to `bd create`

```go
createCmd.Flags().String("body-file", "", "Read description from file (use - for stdin)")
createCmd.Flags().String("description-file", "", "Alias for --body-file")
```

### 2. Flag precedence

- If `--body-file` or `--description-file` is provided, read from file
- If value is `-`, read from stdin
- Otherwise fall back to `--body` or `--description` flag
- If neither provided, description is empty (current behavior)

### 3. Error handling

- File doesn't exist → clear error message
- File not readable → clear error message
- stdin specified but not available → clear error message

## Benefits

✅ **Matches training data**: `gh issue create --body-file file.txt` is a common pattern
✅ **No shell escaping issues**: File content is read directly
✅ **Works with any content**: Markdown, special characters, quotes, etc.
✅ **Agent-friendly**: Agents already write complex content to temp files
✅ **User-friendly**: Easier for humans too when pasting long descriptions

## Related Commands

Consider adding similar support to:
- `bd update --body-file` (for updating descriptions)
- `bd comment --body-file` (if/when we add comments)

## Examples

```bash
# From file
bd create --title="Add new feature" --body-file=feature.md

# From stdin
echo "Quick description" | bd create --title="Bug fix" --body-file=-

# With other flags
bd create \
  --title="Security issue" \
  --type=bug \
  --priority=0 \
  --body-file=security-report.md \
  --label=security
```

## Testing

- Test with normal files
- Test with stdin (`-`)
- Test with non-existent files (error handling)
- Test with binary files (should handle gracefully)
- Test with empty files (valid - empty description)
- Test that `--description-file` and `--body-file` are equivalent aliases


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


Jira import script (jira2jsonl.py)

Create a Python script to import Jira issues into beads JSONL format.

**Pattern**: Follow examples/github-import/gh2jsonl.py

**Features needed**:
- Fetch issues via Jira REST API with JQL queries
- Pagination handling (100 issues per request)
- Map Jira fields to beads fields (see schema mapping in epic)
- Set external_ref to Jira issue URL for re-sync
- Support both Jira Cloud and Server/Data Center APIs
- Read config from bd config (jira.url, jira.project, jira.api_token)

**Config-driven mapping**:
- jira.status_map.* for status conversion
- jira.type_map.* for issue type conversion
- jira.priority_map.* for priority conversion

**Usage**:
```bash
python jira2jsonl.py --project PROJ | bd import
# or
python jira2jsonl.py --jql 'project=PROJ AND status\!=Done' | bd import
```

**Output**: JSONL with external_ref set to Jira issue URL


No logging/debugging for tombstone resurrection events

Per the design document bd-zvg Open Question 1: Should resurrection log a warning? Recommendation was Yes. Currently, when an expired tombstone loses to a live issue (resurrection), there is no logging or debugging output. This makes it hard to understand why an issue reappeared. Recommendation: Add optional debug logging when resurrection occurs, e.g., Issue bd-abc resurrected (tombstone expired). Files: internal/merge/merge.go:359-366, 371-378, 400-405, 410-415


Implement clone-scoped ID allocation to prevent N-way collisions

## Problem
Current ID allocation uses per-clone atomic counters (issue_counters table) that sync based on local database state. In N-way collision scenarios:
- Clone B sees {test-1} locally, allocates test-2
- Clone D sees {test-1, test-2, test-3} locally, allocates test-4
- When same content gets assigned test-2 and test-4, convergence fails

Root cause: Each clone independently allocates IDs without global coordination, leading to overlapping assignments for the same content.

## Solution
Add clone UUID to ID allocation to make every ID globally unique:

**Current format:** `test-1`, `test-2`, `test-3`
**New format:** `test-1-a7b3`, `test-2-a7b3`, `test-3-c4d9`

Where suffix is first 4 chars of clone UUID.

## Implementation

### 1. Add clone_identity table
```sql
CREATE TABLE clone_identity (
    clone_uuid TEXT PRIMARY KEY,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
```

### 2. Modify getNextIDForPrefix()
```go
func (s *SQLiteStorage) getNextIDForPrefix(ctx context.Context, prefix string) (string, error) {
    cloneUUID := s.getOrCreateCloneUUID(ctx)
    shortUUID := cloneUUID[:4]

    nextNum := s.getNextCounterForPrefix(ctx, prefix)
    return fmt.Sprintf("%s-%d-%s", prefix, nextNum, shortUUID), nil
}
```

### 3. Update ID parsing logic
All places that parse IDs (utils.ExtractIssueNumber, etc.) need to handle new format.

### 4. Migration strategy
- Existing IDs remain unchanged (no suffix)
- New IDs get clone suffix automatically
- Display layer can hide suffix in UI: `bd-cb64c226.3-a7b3` → `#42`

## Benefits
- **Zero collision risk**: Same content in different clones gets different IDs
- **Maintains readability**: Still sequential numbering within clone
- **No coordination needed**: Works offline, no central authority
- **Scales to 100+ clones**: 4-char hex = 65,536 unique clones

## Concerns
- ID format change may break existing integrations
- Need migration path for existing databases
- Display logic needs update to hide/show suffixes appropriately

## Success Criteria
- 10+ clone collision test passes without failures
- Existing issues continue to work (backward compatibility)
- Documentation updated with new ID format
- Migration guide for v1.x → v2.x

## Timeline
Medium-term (v1.1-v1.2), 2-3 weeks implementation

Daemon race condition: stale export overwrites recent DB changes

**Symptom:**
Merged bd-fc2d into bd-fb05 in ~/src/beads (commit ce4d756), pushed to remote. The ~/src/fred/beads daemon then exported its stale DB state and committed (8cc1bb4), reverting bd-fc2d back to "open" status.

**Timeline:**
1. 21:45:12 - Merge committed from ~/src/beads (ce4d756): bd-fc2d closed
2. 21:49:42 - Daemon in ~/src/fred/beads exported stale state (8cc1bb4): bd-fc2d open again

**Root cause:**
The fred/beads daemon had a stale database (bd-fc2d still open) and didn't auto-import the newer JSONL before exporting. When it exported, it overwrote the merge with its stale state.

**Expected behavior:**
Daemon should detect that JSONL is newer than its last export and import before exporting.

**Actual behavior:**
Daemon exported stale DB state, creating a conflicting commit that reverted upstream changes.

**Impact:**
Multi-workspace setups with daemons can silently lose changes if one daemon has stale state and exports.


bd-hv01: Add comprehensive edge case tests for deletion tracking

Need to add tests for: corrupted snapshot file, stale snapshot (> 1 hour), concurrent sync operations (daemon + manual), partial deletion failure, empty remote JSONL, multi-repo mode with deletions, git worktree scenario.

Also refine TestDeletionWithLocalModification to check for specific conflict error instead of accepting any error.

Fix FOREIGN KEY constraint failures in AddComment and ApplyCompaction

The 'CloseIssue', 'UpdateIssueID', and 'RemoveLabel' methods were fixed in PR #348 to prevent foreign key constraint failures when operating on non-existent issues.

However, the Oracle identified two other methods that follow the same problematic pattern:
1. `AddComment` (in `internal/storage/sqlite/events.go`)
2. `ApplyCompaction` (in `internal/storage/sqlite/compact.go`)

These methods attempt to insert an event record after updating the issue, without verifying that the issue update actually affected any rows. This leads to a foreign key constraint failure if the issue does not exist.

We need to:
1. Create reproduction tests for these failure cases
2. Apply the same fix pattern: check `RowsAffected()` after the update, and return a proper "issue not found" error if it is 0, before attempting to insert the event.
3. Standardize the error message format to "issue %s not found" or "issue not found: %s" for consistency.


Pre-push hook and daemon export produce different JSONL

After committing and pushing, git status shows .beads/beads.jsonl as dirty. Investigation shows:

1. Pre-push hook ran successfully and exported DB → JSONL
2. Push completed
3. Shortly after, daemon exported DB → JSONL again with different content
4. Diff shows comments added to old issues (bd-23a8, bd-6049, bd-87a0)

Timeline:
- Commit c731c45 "Update beads JSONL"
- Pre-push hook exported JSONL
- Push succeeded
- Daemon PID 33314 exported again with different content

Questions:
1. Did someone run a command between commit and daemon export?
2. Is there a timing issue where pre-push hook doesn't capture all DB changes?
3. Should pre-commit hook flush daemon changes before committing?

The comments appear to be from Nov 5 (created_at: 2025-11-05T08:38:46Z) but are only appearing in JSONL now. This suggests the DB had these comments but they weren't exported during pre-push.

Possible causes:
- Pre-push hook uses BEADS_NO_DAEMON=1 which might skip pending writes
- Daemon has unflushed changes in memory
- Race condition between pre-push export and daemon's periodic export

Improved fix based on oracle code review:
1. Pre-push now flushes pending changes first (prevents debounce race)
2. Uses git status --porcelain to catch all change types
3. Handles both beads.jsonl and issues.jsonl
4. Works even if bd not installed (git-only check)

Fix TestFallbackToDirectModeEnablesFlush deadlock causing 10min test timeout

## Problem

TestFallbackToDirectModeEnablesFlush in direct_mode_test.go deadlocks for 9m59s before timing out, causing the entire test suite to take 10+ minutes instead of <10 seconds.

## Root Cause

Database lock contention between test cleanup and flushToJSONL():
- Test cleanup (line 36) tries to close DB via defer
- flushToJSONL() (line 132) is still accessing DB
- Results in deadlock: database/sql.(*DB).Close() waits for mutex while GetJSONLFileHash() holds it

## Stack Trace Evidence

```
goroutine 512 [sync.Mutex.Lock, 9 minutes]:
database/sql.(*DB).Close(0x14000643790)
  .../database/sql/sql.go:927 +0x84
github.com/steveyegge/beads/cmd/bd.TestFallbackToDirectModeEnablesFlush.func1()
  .../direct_mode_test.go:36 +0xf4

While goroutine running flushToJSONL() holds DB connection via GetJSONLFileHash()
```

## Impact

- Test suite: 10+ minutes → should be <10 seconds
- ALL other tests pass in ~4 seconds
- This ONE test accounts for 99.9% of test runtime

## Related

This is the EXACT same issue documented in MAIN_TEST_REFACTOR_NOTES.md for why main_test.go refactoring was deferred - global state manipulation + DB cleanup = deadlock.

## Fix Approaches

1. **Add proper cleanup sequencing** - stop flush goroutines BEFORE closing DB
2. **Use test-specific DB lifecycle** - ensure flush completes before cleanup
3. **Mock the flush mechanism** - avoid real DB for testing this code path
4. **Add explicit timeout handling** - fail fast with clear error instead of hanging

## Files

- cmd/bd/direct_mode_test.go:36-132
- cmd/bd/autoflush.go:353 (validateJSONLIntegrity)
- cmd/bd/autoflush.go:508 (flushToJSONLWithState)

## Acceptance

- Test passes without timeout
- Test suite completes in <10 seconds
- No deadlock between cleanup and flush operations

bd prime: Detect ephemeral branches and adjust workflow output

When 'bd prime' runs on a branch with no upstream (ephemeral branch), it should output a different SESSION CLOSE PROTOCOL.

**Current output (wrong for ephemeral branches):**
```
[ ] 1. git status
[ ] 2. git add <files>
[ ] 3. bd sync
[ ] 4. git commit -m "..."
[ ] 5. bd sync
[ ] 6. git push
```

**Needed output for ephemeral branches:**
```
[ ] 1. git status
[ ] 2. git add <files>
[ ] 3. bd sync --from-main  (pull updates from main)
[ ] 4. git commit -m "..."
[ ] 5. (no push - branch is ephemeral)
```

**Detection:** `git rev-parse --abbrev-ref --symbolic-full-name @{u}` returns error code 128 if no upstream.

Also update Sync & Collaboration section to mention `bd sync --from-main` for ephemeral branches.

**Use case:** Gastown polecats work on ephemeral local branches that are never pushed. Their code gets merged to main via local merge, and beads changes stay local (communicated via gm mail to Overseer).


Replace BEADS_DB with BEADS_DIR environment variable

Implement BEADS_DIR as a replacement for BEADS_DB to point to the .beads directory instead of the database file directly.

Rationale:
- With --no-db mode, there's no .db file to point to
- The .beads directory is the logical unit (contains config.yaml, db files, jsonl files)
- More intuitive: point to the beads directory not the database file

Implementation:
1. Add BEADS_DIR environment variable support
2. Maintain backward compatibility with BEADS_DB
3. Priority order: BEADS_DIR > BEADS_DB > auto-discovery
4. If BEADS_DIR is set, look for config.yaml in that directory to find actual database path
5. Update documentation and migration guide

Files to modify:
- beads.go (FindDatabasePath function)
- cmd/bd/main.go (initialization)
- Documentation (CLI_REFERENCE.md, TROUBLESHOOTING.md, etc.)
- MCP integration (integrations/beads-mcp/src/beads_mcp/config.py)

Testing:
- Ensure BEADS_DB still works (backward compatibility)
- Test BEADS_DIR with both db and --no-db modes
- Test priority order when both are set
- Update integration tests

Testing & Validation

Ensure reliability through comprehensive testing.

Completed comprehensive Agent Mail test coverage analysis and implementation.

**Test Coverage Summary:**
- 66 total tests across 5 files
- 51 unit tests for HTTP adapter (0.02s)
- 15 integration tests for multi-agent scenarios (~55s total)

**New Tests Added:**
Created `test_multi_agent_coordination.py` (4 tests, 11s) covering:
1. Fairness: 10 agents competing for 5 issues → exactly 1 claim per issue
2. Notifications: End-to-end message delivery between agents
3. Handoff: Clean reservation transfer from agent1 to agent2
4. Idempotency: Double reserve/release by same agent

**Coverage Quality:**
✅ Collision prevention (race conditions)
✅ Graceful degradation (7 failure modes)
✅ TTL/expiration behavior
✅ Multi-agent coordination
✅ JSONL consistency
✅ HTTP error handling
✅ Authorization and configuration

**Intentionally Skipped:**
- Path traversal (validated elsewhere)
- Retry policies (nice-to-have)
- HTTPS/TLS (out of scope)
- Slow tests (50+ agents, soak tests)

See `tests/integration/AGENT_MAIL_TEST_COVERAGE.md` for details.

All tests pass. Agent Mail integration is well-tested and reliable for multi-agent scenarios.

YABB: Spurious issue updates during normal operations

Issue bd-627d was updated during config refactoring session without any actual changes to it. Only timestamps and content_hash changed.

Observed: Running various bd commands (list, create, etc.) caused bd-627d updated_at to change from 14:14 to 14:31.

Expected: Issues should only be updated when explicitly modified.

This causes:
- Dirty JSONL after every session
- False conflicts in git
- Confusing git history

Likely culprit: Daemon auto-import/export cycle or database migration touching all issues.

Investigated thoroughly - unable to reproduce. The import logic has IssueDataChanged() checks before calling UpdateIssue (importer/importer.go:458). All tests pass. May have been fixed by recent refactorings. Closing as cannot reproduce - please reopen with specific repro steps if it occurs again.


Rename last_import_hash metadata key to jsonl_content_hash

The metadata key 'last_import_hash' is misleading because it's updated on both import AND export (sync.go:614, import.go:320).

Better names:
- jsonl_content_hash (more accurate)
- last_sync_hash (clearer intent)

This is a breaking change requiring migration of existing metadata values.


GH#245: Windows MCP subprocess timeout for git rev-parse

User reports git detection timing out on Windows in MCP server, but CLI works fine.

Path: C:\Users\chris\Documents\DEV_R\quarto-cli
Error: Git repository detection timed out after 5s
Works fine in CLI: `git rev-parse --show-toplevel` succeeds

Hypothesis: subprocess.run() with asyncio.to_thread() may have Windows-specific issues or the MCP runtime environment may not have proper PATH/git access.

Potential fixes:
1. Add subprocess shell=True on Windows
2. Increase timeout further for Windows
3. Add better error logging to capture subprocess stderr
4. Skip git resolution entirely on timeout and just use provided path


Remove misleading placeholder 'bd merge' command from duplicates output

**Problem:**
The `bd duplicates` command suggests running a command that doesn't exist:
```
bd merge <source-ids> --into <target-id>
```

This is confusing because:
1. `bd merge` is actually a git 3-way JSONL merge driver (takes 4 file paths)
2. The suggested syntax for merging duplicate issues is not implemented
3. Line 75 in duplicates.go even has: `// TODO: performMerge implementation pending`

**Current behavior:**
- Users see suggested command that doesn't work
- No indication that feature is unimplemented
- Related to issue #349 item #2

**Proposed fix:**
Replace line 77 in cmd/bd/duplicates.go with either:

Option A (conservative):
```go
cmd := fmt.Sprintf("# TODO: Merge %s into %s (merge command not yet implemented)",
    strings.Join(sources, " "), target.ID)
```

Option B (actionable):
```go
cmd := fmt.Sprintf("# Duplicate found: %s\n# Manual merge: Close duplicates with 'bd close %s' and link to %s as 'related'",
    strings.Join(sources, " "), strings.Join(sources, " "), target.ID)
```

**Files to modify:**
- cmd/bd/duplicates.go (line ~77)


Remove unreachable RPC methods

Several RPC server and client methods are unreachable and should be removed:

Server methods (internal/rpc/server.go):
- `Server.GetLastImportTime` (line 2116)
- `Server.SetLastImportTime` (line 2123)
- `Server.findJSONLPath` (line 2255)

Client methods (internal/rpc/client.go):
- `Client.Import` (line 311) - RPC import not used (daemon uses autoimport)

Evidence:
```bash
go run golang.org/x/tools/cmd/deadcode@latest -test ./...
```

Impact: Removes ~80 LOC of unused RPC code


Modify CreateIssue to support parent resurrection

Update internal/storage/sqlite/sqlite.go:182-196 to call TryResurrectParent before failing on missing parent. Coordinate with EnsureIDs changes for consistent behavior. Handle edge case where parent never existed in JSONL (fail gracefully).


Sync protection mechanism resurrects deleted issues

During bd sync, the 'Protecting N issue(s) from left snapshot' logic resurrects issues that are in the deletions manifest, causing UNIQUE constraint failures on subsequent syncs.

## Reproduction
1. Delete an issue with bd delete (creates tombstone + deletions.jsonl entry)
2. Run bd sync - succeeds
3. Run bd sync again - fails with 'UNIQUE constraint failed: issues.id'

## Root Cause
The protection mechanism (designed to prevent data loss during 3-way merge) keeps a snapshot of issues before sync. When importing after pull, it restores issues from this snapshot even if they're in the deletions manifest.

## Observed Behavior
- bd-3pd was deleted and added to deletions.jsonl
- First sync exports tombstone, commits, pulls, imports - succeeds
- Second sync: protection restores bd-3pd from left snapshot
- Import tries to create bd-3pd which already exists → UNIQUE constraint error

## Expected Behavior
Issues in deletions manifest should NOT be restored by protection mechanism.

## Workaround
Manually delete from DB: sqlite3 .beads/beads.db 'DELETE FROM issues WHERE id = "bd-xxx"'

## Files to Investigate
- cmd/bd/sync.go - protection logic
- cmd/bd/snapshot_manager.go - left snapshot handling
- internal/importer/importer.go - import with protection


Tombstone import creates duplicate entries when deletions.jsonl has entries already in JSONL

In the tombstone import logic (bd-dve), when a non-tombstone issue is in both JSONL and deletions.jsonl, we:
1. Skip the issue (line 149-155)
2. Create a tombstone from deletions.jsonl (lines 161-171)

This means if the JSONL contains issue 'bd-abc' (non-tombstone) and deletions.jsonl also has 'bd-abc', we skip the JSONL version but then add a tombstone version from deletions.jsonl. This is intentional but the skipped issue count may be confusing.

Consider: should we track converted-to-tombstone separately from skipped-deleted in the Result struct?


bd sync --squash: batch multiple syncs into single commit

For solo developers who don't need real-time multi-agent coordination, add a --squash option to bd sync that accumulates changes and commits them in a single commit rather than one commit per sync.

This addresses the git history pollution concern (many 'bd sync: timestamp' commits) while preserving the default behavior needed for orchestration.

**Proposed behavior:**
- `bd sync --squash` accumulates pending exports without committing
- Commits accumulated changes on session end or explicit `bd sync` (without --squash)
- Default behavior unchanged (immediate commits for orchestration)

**Use case:** Solo developers who want cleaner git history but don't need real-time coordination between agents.

**Related:** PR #411 (docs: reduce bd sync commit pollution)
**See also:** Multi-repo support as alternative solution (docs/MULTI_REPO_AGENTS.md)


Mass deletion logging for forensics

Log detailed information when the safety check triggers during auto-push.

When >50% issues vanish AND >5 existed:
- Log which issues vanished
- Log the before/after counts
- Log timestamp for forensic analysis

This gives users visibility into what happened if something goes wrong, without blocking the sync.

Verify MCP Server Compatibility

Ensure MCP server works with cache-free daemon


Git history fallback doesn't escape regex special chars in IDs

## Problem

In `batchCheckGitHistory`, IDs are directly interpolated into a regex pattern:

```go
patterns = append(patterns, fmt.Sprintf(\`"id":"%s"\`, id))
searchPattern := strings.Join(patterns, "|")
cmd := exec.Command("git", "log", "--all", "-G", searchPattern, ...)
```

If an ID contains regex special characters (e.g., `bd-foo.bar` or `bd-test+1`), the pattern will be malformed or match unintended strings.

## Location
`internal/importer/importer.go:923-926`

## Impact
- False positives: IDs with `.` could match any character
- Regex errors: IDs with `[` or `(` could cause git to fail
- Security: potential for regex injection (low risk since IDs are validated)

## Fix
Escape regex special characters:

```go
import "regexp"

escapedID := regexp.QuoteMeta(id)
patterns = append(patterns, fmt.Sprintf(\`"id":"%s"\`, escapedID))
```


Integration Testing

Audit all cmd/bd tests and group into suites

Analyze all 279 tests in cmd/bd and identify:
1. Which tests can share DB setup (most of them\!)
2. Which tests actually need isolation (export/import, git ops)
3. Optimal grouping into test suites

Create a mapping document showing:
- Current: 279 individual test functions
- Proposed: ~10-15 test suites with subtests
- Expected speedup per suite

Blocks all refactoring work.


Fix revive style issues (78 issues)

Style violations: unused parameters (many cmd/args in cobra commands), missing exported comments, stuttering names (SQLiteStorage), indent-error-flow issues.

Fixed 19 revive issues:
- 14 unused-parameter (renamed to _)
- 2 redefines-builtin-id (max→maxCount, min→minInt)
- 3 indent-error-flow (gofmt fixed 2, skipped 1 complex nested one)

Remaining issues are acceptable: 11 unused-params in deeper code, 2 empty-blocks with comments, 1 complex indent case, 1 superfluous-else in test.


Delete skipped tests for "old buggy behavior"

Three test functions are permanently skipped with comments indicating they test behavior that was fixed in GH#120. These tests will never run again and should be deleted.

Test functions to remove:

1. `cmd/bd/import_collision_test.go:228`
   ```go
   t.Skip("Test expects old buggy behavior - needs rewrite for GH#120 fix")
   ```

2. `cmd/bd/import_collision_test.go:505`
   ```go
   t.Skip("Test expects old buggy behavior - needs rewrite for GH#120 fix")
   ```

3. `internal/storage/sqlite/collision_test.go:919`
   ```go
   t.Skip("Test expects old buggy behavior - needs rewrite for GH#120 fix")
   ```

Impact: Removes ~150 LOC of permanently skipped tests


Update flake.nix vendorHash after dependency bumps

The Nix flake CI is failing due to stale vendorHash.

Error from CI:
```
error: hash mismatch in fixed-output derivation beads-0.24.4-go-modules.drv
```

Root cause: go.mod/go.sum was updated by dependabot (wazero, anthropic-sdk-go, etc.) but flake.nix vendorHash wasn't updated.

## Immediate Fix
Run `nix build` locally, get the correct hash from the error message, update flake.nix.

## Long-term Fix
Add a GitHub Action that auto-updates vendorHash when go.mod/go.sum changes:
1. Trigger on push to main when go.mod/go.sum changes
2. Run `nix build` to get the new hash from the error
3. Update flake.nix with the correct hash
4. Commit and push

Add path normalization to getMultiRepoJSONLPaths()

From bd-xo6b code review: getMultiRepoJSONLPaths() does not handle non-standard paths correctly.

Problems:
- No tilde expansion: ~/repos/foo treated as literal path
- No absolute path conversion: ../other-repo breaks if working directory changes
- No duplicate detection: If Primary=. and Additional=[.], same JSONL processed twice
- No empty string handling: Empty paths create invalid /.beads/issues.jsonl

Impact:
Config with tilde or relative paths will fail

Fix needed:
1. Use filepath.Abs() for all paths
2. Add tilde expansion via os.UserHomeDir()
3. Deduplicate paths (use map to track seen paths)
4. Filter out empty strings
5. Validate paths exist and are readable

Test label update feature


Measure notification latency vs git sync

Benchmark end-to-end latency for status updates to propagate between agents using both methods.

Acceptance Criteria:
- Measure git sync latency (commit → push → pull → import)
- Measure Agent Mail latency (send_message → fetch_inbox)
- Document latency distribution (p50, p95, p99)
- Verify <100ms claim for Agent Mail
- Compare against 1-5s baseline for git

Success Metric: Agent Mail latency < 100ms, git sync latency > 1000ms

Latency benchmark completed. Results documented in latency_results.md:
- Git sync: 2000-5000ms (full cycle with network)
- Agent Mail: <100ms (HTTP API round-trip)
- Confirms 20-50x latency reduction claim

Refactor sqlite.go (2298 lines)

Break down internal/storage/sqlite/sqlite.go into smaller, more focused modules. The file is currently 2298 lines and should be split into logical components.


Fix CI failures before 0.21.3 release

CI is failing on multiple jobs:
1. Nix flake: Tests fail due to missing git in build environment
2. Windows tests: Need to check what's failing
3. Linux tests: Need to check what's failing
4. Linter errors: Many unchecked errors need fixing

Need to fix before tagging v0.21.3 release.

Fixed linter errors (errcheck, misspell), Nix flake git dependency, and import database discovery bug. Tests still failing - need to investigate further.


Add uninstall documentation (GH #445)


Add tests for Integration Layer Implementation

While implementing bd-wfmw, noticed missing tests

Reviewed existing coverage:
- Basic test coverage exists in lib/test_beads_mail_adapter.py
- Integration tests cover failure scenarios in tests/integration/test_mail_failures.py
- Good coverage of: enabled/disabled modes, graceful degradation, 409 conflicts, HTTP errors, config
- Missing: authorization headers detail, request body structure validation, concurrent reservation timing, TTL edge cases


Improve CheckStaleness error handling

## Problem

CheckStaleness returns 'false' (not stale) for multiple error conditions instead of returning errors. This masks problems.

**Location:** internal/autoimport/autoimport.go:253-285

## Edge Cases That Return False

1. **Invalid last_import_time format** (line 259-262)
   - Corrupted metadata returns 'not stale'
   - Could show stale data

2. **No JSONL file found** (line 267-277)
   - If glob fails, falls back to 'issues.jsonl'
   - If that's empty, returns 'not stale'

3. **JSONL stat fails** (line 279-282)
   - Permission denied, file missing
   - Returns 'not stale' even though can't verify

## Current Code

```go
lastImportTime, err := time.Parse(time.RFC3339, lastImportStr)
if err \!= nil {
    return false, nil  // ← Should return error
}

// ...

if jsonlPath == "" {
    return false, nil  // ← Should return error
}

stat, err := os.Stat(jsonlPath)
if err \!= nil {
    return false, nil  // ← Should return error
}
```

## Fix

```go
lastImportTime, err := time.Parse(time.RFC3339, lastImportStr)
if err \!= nil {
    return false, fmt.Errorf("corrupted last_import_time: %w", err)
}

// ...

if jsonlPath == "" {
    return false, fmt.Errorf("no JSONL file found")
}

stat, err := os.Stat(jsonlPath)
if err \!= nil {
    return false, fmt.Errorf("cannot stat JSONL: %w", err)
}
```

## Impact
Medium - edge cases are rare but should be handled

## Effort
30 minutes - requires updating callers in RPC server

## Dependencies
Requires: bd-n4td (warning on errors)

Code Review Sweep: thorough

Perform thorough code review sweep based on accumulated activity.

**AI Reasoning:**
Significant code volume added (150,273 lines) across multiple critical areas, including cmd/bd, internal/storage/sqlite, and internal/rpc. High file change count (616) indicates substantial refactoring or new functionality. The metrics suggest potential for subtle architectural or implementation issues that warrant review.

**Scope:** thorough
**Target Areas:** cmd/bd, internal/storage/sqlite, internal/rpc
**Estimated Files:** 12
**Estimated Cost:** $5

**Task:**
Review files for non-obvious issues that agents miss during focused work:
- Inefficiencies (algorithmic, resource usage)
- Subtle bugs (race conditions, off-by-one, copy-paste)
- Poor patterns (coupling, complexity, duplication)
- Missing best practices (error handling, docs, tests)
- Unnamed anti-patterns

File discovered issues with detailed reasoning and suggestions.


Review multi-repo deletion tracking implementation

Thoroughly review the multi-repo deletion tracking fix (bd-4oob):

Files changed:
- cmd/bd/deletion_tracking.go: Added getMultiRepoJSONLPaths() helper
- cmd/bd/daemon_sync.go: Updated snapshot capture/update logic for multi-repo
- cmd/bd/deletion_tracking_test.go: Added 2 new tests (287 lines)

Review focus areas:
1. Correctness: Does getMultiRepoJSONLPaths() handle all edge cases?
2. Performance: Calling getMultiRepoJSONLPaths() 3x per sync (snapshot capture, merge, base update) - should we cache?
3. Error handling: What if some repos fail snapshot operations but others succeed?
4. Race conditions: Multiple daemons in different repos?
5. Test coverage: Are TestMultiRepoDeletionTracking and TestMultiRepoSnapshotIsolation sufficient?
6. Path handling: Absolute vs relative paths, tilde expansion

This is fresh code - needs careful review before considering deletion tracking production-ready.

Code review completed. Overall assessment: Core deletion tracking logic is sound, but error handling and path handling issues make this not yet production-ready for multi-repo scenarios.

Key findings:

CRITICAL ISSUES (Priority 1):
1. Inconsistent error handling in daemon_sync.go - snapshot/merge fail hard but base update warns. Can leave DB in inconsistent state with no rollback. See bd-sjmr.
2. No path normalization in getMultiRepoJSONLPaths() - tilde expansion, relative paths, duplicates not handled. See bd-iye7.

SHOULD FIX (Priority 2):
3. Missing test coverage for edge cases - empty paths, duplicates, partial failures. See bd-kdoh.
4. Performance - getMultiRepoJSONLPaths() called 3x per sync (minor issue). See bd-we4p.

WHAT WORKS WELL:
- Atomic file operations with PID-based temp files
- Good snapshot isolation between repos
- Race condition protection via exclusive locks
- Solid test coverage for happy path scenarios

VERDICT: Address bd-iye7 and bd-sjmr before considering deletion tracking production-ready for multi-repo mode.

Detailed review notes available in conversation history.


Refactor duplicate JSONL-from-git parsing code

Both readFirstIssueFromGit() in init.go and importFromGit() in autoimport.go have similar code patterns for:
1. Running git show <ref>:<path>
2. Scanning the output with bufio.Scanner
3. Parsing JSON lines

Could be refactored to share a helper like:
- readJSONLFromGit(gitRef, path string) ([]byte, error)
- Or a streaming version: streamJSONLFromGit(gitRef, path string) (io.Reader, error)

Files:
- cmd/bd/autoimport.go:225-256 (importFromGit)
- cmd/bd/init.go:1212-1243 (readFirstIssueFromGit)

Priority is low since code duplication is minimal and both functions work correctly.


Implement "bd daemons logs" subcommand

Add command to view daemon logs for a specific workspace. Requires daemon logging to file (may need separate issue for log infrastructure).


Tombstone fields not merged in mergeIssue function

The mergeIssue() function in merge.go does not handle tombstone fields (DeletedAt, DeletedBy, DeleteReason, OriginalType) when merging live issues. While tombstones are handled separately in merge3WayWithTTL(), if a tombstone ever reaches mergeIssue() via the mergeStatus safety fallback, the tombstone fields would be lost. The mergeIssue() function should either: 1) Copy tombstone fields when result.Status becomes tombstone, or 2) Assert that tombstones never reach mergeIssue() (defensive check). Files: internal/merge/merge.go:458-499


Add .beads/README.md during 'bd init' for project documentation and promotion

When 'bd init' is run, automatically generate a .beads/README.md file that:

1. Briefly explains what Beads is (AI-native issue tracking that lives in your repo)
2. Links to the main repository: https://github.com/steveyegge/beads
3. Provides a quick reference of essential commands:
   - bd create: Create new issues
   - bd list: View all issues
   - bd update: Modify issue status/details
   - bd show: View issue details
   - bd sync: Sync with git remote
4. Highlights key benefits for AI coding agents and developers
5. Encourages developers to try it out

The README should be enthusiastic and compelling to get open source contributors excited about using Beads for their AI-assisted development workflows.

Workaround for FastMCP outputSchema bug in Claude Code

The beads MCP server (v0.23.1) successfully connects to Claude Code, but all tools fail to load with a schema validation error due to a bug in FastMCP 2.13.1.

Error: "Invalid literal value, expected \"object\"" in outputSchema.

Root Cause: FastMCP generates outputSchema with $ref at root level without "type": "object" for self-referential models (Issue).

Workaround: Use slash commands (/beads:ready) or wait for FastMCP fix.

- Manual installation steps for post-init setup


bd-hv01: No snapshot versioning or timestamps causes stale data usage

Problem: If sync is interrupted (crash, kill -9, power loss), stale snapshots persist indefinitely. Next sync uses stale data leading to incorrect deletions.

Fix: Add metadata to snapshots with timestamp, version, and commit SHA. Validate snapshots are recent (< 1 hour old), from compatible version, and from expected git commit.

Files: cmd/bd/deletion_tracking.go (all snapshot functions)


bd-hv01: Non-atomic snapshot operations can cause data loss

## Problem
In sync.go:146-155 and daemon_sync.go:502-505, snapshot capture failures are logged as warnings but sync continues:

```go
if err := exportToJSONL(ctx, jsonlPath); err != nil { ... }
if err := captureLeftSnapshot(jsonlPath); err != nil {
    fmt.Fprintf(os.Stderr, "Warning: failed to capture snapshot...")
}
```

If export succeeds but snapshot capture fails, the merge uses stale snapshot data, potentially deleting wrong issues.

## Impact
- Critical data integrity issue
- Could delete issues incorrectly during multi-workspace sync

## Fix
Make snapshot capture mandatory:
```go
if err := captureLeftSnapshot(jsonlPath); err != nil {
    return fmt.Errorf("failed to capture snapshot (required for deletion tracking): %w", err)
}
```

## Files Affected
- cmd/bd/sync.go:146-155
- cmd/bd/daemon_sync.go:502-505

Recurring dirty state after merge conflicts - bd sync keeps failing

## Problem

`bd sync` consistently fails with merge conflicts in `.beads/beads.jsonl`, creating a loop:
1. User runs `bd sync`
2. Git merge conflict occurs
3. User resolves with `git checkout --theirs` (takes remote)
4. Daemon auto-exports database state (which has local changes)
5. JSONL becomes dirty again immediately
6. Repeat

This has been happening for **weeks** and is extremely frustrating.

## Root Cause

The recommended conflict resolution (`git checkout --theirs`) throws away local database state (comments, dependencies, closed issues). The daemon then immediately re-exports, creating a dirty state.

## Current Workaround

Manual `bd export -o .beads/beads.jsonl && git add && git commit && git push` after every failed sync.

## Example Session

```bash
$ bd sync
CONFLICT (content): Merge conflict in .beads/beads.jsonl

$ git checkout --theirs .beads/beads.jsonl && bd import && git add && git commit && git push
# Pushed successfully

$ git status
modified: .beads/beads.jsonl  # DIRTY AGAIN!
```

## Lost Data in Recent Session

- bd-ry1u closure (lost in merge)
- Comments on bd-08fd, bd-23a8, bd-6049, bd-87a0 (lost)
- Dependencies that existed only in local DB

## Potential Solutions

1. **Use beads-merge tool** - Implement proper 3-way JSONL merge (bd-bzfy)
2. **Smarter conflict resolution** - Detect when `--theirs` will lose data, warn user
3. **Sync validation** - Check if JSONL == DB after merge, re-export if needed
4. **Daemon awareness** - Pause auto-export during merge resolution
5. **Transaction log** - Replay local changes after merge instead of losing them

## Related Issues

- bd-bzfy (beads-merge integration)
- Possibly related to daemon auto-export behavior

## Solution Implemented

Fixed the recurring dirty state after merge conflicts by adding **sync validation** before re-exporting.

### Root Cause
Lines 217-237 in `sync.go` unconditionally re-exported DB to JSONL after every import, even when they were already in sync. This created an infinite loop:
1. User runs `bd sync` which pulls and imports remote JSONL
2. Sync unconditionally re-exports DB (which has local changes)
3. JSONL becomes dirty immediately
4. Repeat

### Fix
Added `dbNeedsExport()` function in `integrity.go` that checks:
- If JSONL exists
- If DB modification time is newer than JSONL
- If DB and JSONL issue counts match

Now `bd sync` only re-exports if DB actually has changes that differ from JSONL.

### Changes
- Added `dbNeedsExport()` in `cmd/bd/integrity.go` (lines 228-271)
- Updated `sync.go` lines 217-251 to check before re-exporting
- Added comprehensive tests in `cmd/bd/sync_merge_test.go`

### Testing
All tests pass including 4 new tests:
- `TestDBNeedsExport_InSync` - Verifies no export when synced
- `TestDBNeedsExport_DBNewer` - Detects DB modifications
- `TestDBNeedsExport_CountMismatch` - Catches divergence
- `TestDBNeedsExport_NoJSONL` - Handles missing JSONL

This prevents the weeks-long frustration of merge conflicts causing infinite dirty loops.
