Deletions not propagated across multi-workspace sync

## Problem

When working with multiple beads workspaces (clones) sharing the same git remote, deleted issues keep coming back.

## Reproduction

1. Clone A deletes issue `bd-xyz` via `bd delete bd-xyz --force`
2. Clone A daemon syncs and pushes to GitHub
3. Clone B still has `bd-xyz` in its database
4. Clone B daemon exports and pushes its JSONL
5. Clone A pulls and imports → `bd-xyz` comes back!

## Root Cause

**No deletion tracking mechanism.** The system has no way to distinguish between:
- "Issue doesn't exist in JSONL because it was deleted"
- "Issue doesn't exist in JSONL because the export is stale"

Import treats missing issues as "not in this export" rather than "explicitly deleted."

## Solution Options

1. **Tombstone records** - Keep deleted issues in JSONL with `"status":"deleted"` or `"deleted_at"` field
2. **Deletion log** - Separate `.beads/deletions.jsonl` file tracking all deleted IDs
3. **Three-way merge** - Import compares: DB state, old JSONL, new JSONL
4. **Manual conflict resolution** - Detect resurrection and prompt user

## Related

- Similar to resurrection logic for orphaned children (bd-cc4f)
- beads-merge tool handles this better with 3-way merge


Add TestThreeCloneCollision for regression protection

Add a 3-clone collision test to document behavior and provide regression protection.

Purpose:
- Verify content convergence regardless of sync order
- Document the ID non-determinism behavior (IDs may be assigned differently based on sync order)
- Provide regression protection for multi-way collisions

Test design:
- 3 clones create same ID with different content
- Test two different sync orders (A→B→C vs C→A→B)
- Assert content sets match (ignore specific ID assignments)
- Add comment explaining ID non-determinism is expected behavior

Known limitation:
- Content always converges correctly (all issues present with correct titles)
- Numeric ID assignments (test-2 vs test-3) depend on sync order
- This is acceptable if content convergence is the primary goal


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


Enhance bd doctor to suggest reset for broken states

Update bd doctor to detect severely broken states and suggest reset.

## Detection Criteria
Suggest reset when:
- Multiple unfixable errors detected
- Corrupted JSONL that can't be repaired
- Schema version mismatch that can't be migrated
- Daemon state inconsistent and unkillable

## Implementation
Add to doctor's check/fix flow:
```go
if unfixableErrors > threshold {
    suggest('State may be too broken to fix. Consider: bd reset')
}
```

## Output Example
```
✗ Found 5 unfixable errors

  Your beads state may be too corrupted to repair.
  Consider running 'bd reset' to start fresh.
  (Use 'bd reset --backup' to save current state first)
```

## Notes
- Don't auto-run reset, just suggest
- This is lower priority, can be done in parallel with main work


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


Clean up merge conflict artifacts in .beads directory

After resolving merge conflicts in .beads/beads.jsonl, leftover artifacts remain as untracked files:
- .beads/beads.base.jsonl
- .beads/beads.left.jsonl

These appear to be temporary files created during merge conflict resolution.

Options to fix:
1. Add these patterns to .beads/.gitignore automatically
2. Clean up these files after successful merge resolution
3. Document that users should delete them manually
4. Add a check in 'bd sync' or 'bd doctor' to detect and remove stale merge artifacts

Preferred solution: Add *.base.jsonl and *.left.jsonl patterns to .beads/.gitignore during 'bd init', and optionally clean them up automatically after successful import.


Make MCP compaction settings configurable (COMPACTION_THRESHOLD, PREVIEW_COUNT)

Currently COMPACTION_THRESHOLD (20) and PREVIEW_COUNT (5) are hardcoded constants at the module level. This prevents users from tuning context engineering behavior.

## Current State
```python
COMPACTION_THRESHOLD = 20  # Compact results with more than 20 issues
PREVIEW_COUNT = 5          # Show first 5 issues in preview
```

## Problems
1. No way for MCP clients to request different preview sizes
2. No way to disable compaction for debugging
3. No way to adapt to different context window sizes
4. Values are not documented in tool schema

## Recommended Solution
Add environment variables or MCP tool parameters:
- `BEADS_MCP_COMPACTION_THRESHOLD` env var (default: 20)
- `BEADS_MCP_PREVIEW_COUNT` env var (default: 5)
- Optional `compact_threshold` and `preview_size` parameters to list/ready tools

## Implementation Notes
- Keep current defaults for backward compatibility
- Read from environment at server initialization
- Document in CONTEXT_ENGINEERING.md
- Add tests verifying env var behavior

Add simple cleanup command to delete closed issues

Users want a simple command to delete all closed issues without requiring Anthropic API key (unlike compact). Requested in GH #243.


wish: a 'continue' or similar cmd/flag which means alter last issue

so many time I create an issue and then have another thought: 'oh, before I did X and it crashed there was ZZZ happening' or 'actually that is P4 not P2'. It would be nice if when `bd {cmd}` is used without a {title} or {id} it just adds or updates the most recently touched issue.

Code Review: PR #551 - Persist close_reason to issues table

Code review of PR #551 which fixes close_reason persistence bug.

## Summary
The PR correctly fixes a bug where close_reason was only stored in the events table, not in the issues.close_reason column. This caused `bd show --json` to return empty close_reason.

## What Was Fixed
- ✅ CloseIssue now updates both close_reason and closed_at
- ✅ ReOpenIssue clears both close_reason and closed_at
- ✅ Comprehensive tests added for both storage and CLI layers
- ✅ Clear documentation in queries.go about dual storage strategy

## Quality Assessment
✅ Tests cover both storage layer and CLI JSON output
✅ Handles reopen case (clearing close_reason)
✅ Good comments explaining dual-storage design
✅ No known issues

## Potential Followups
See linked issues for suggestions.

Implement hash ID generation in CreateIssue

Replace sequential ID generation with hash-based IDs in CreateIssue function.

## Current Behavior (internal/storage/sqlite/sqlite.go)
```go
func (s *SQLiteStorage) CreateIssue(ctx context.Context, issue *types.Issue) error {
    // ID comes from auto-increment counter
    // Collisions possible across clones
}
```

## New Behavior
```go
func (s *SQLiteStorage) CreateIssue(ctx context.Context, issue *types.Issue) error {
    // Generate hash ID if not provided
    if issue.ID == "" {
        issue.ID = idgen.GenerateHashID(
            issue.Title,
            issue.Description,
            time.Now(),
            s.workspaceID,
        )
    }

    // Assign next alias
    issue.Alias = s.getNextAlias()

    // Insert with hash ID + alias
    // ...
}
```

## Workspace ID Generation
Add to database initialization:
```go
// Generate stable workspace ID (persisted in .beads/workspace_id)
workspaceID := getOrCreateWorkspaceID()
```

Options for workspace ID:
1. Hostname + random suffix
2. UUID (random)
3. Git remote URL hash (deterministic per repo)

Recommended: Option 3 (git remote hash) for reproducibility

## Hash Collision Detection
```go
// On insert, check for collision (unlikely but possible)
existing, err := s.GetIssue(ctx, issue.ID)
if err == nil {
    // Hash collision! Add random suffix and retry
    issue.ID = issue.ID + "-" + randomSuffix(4)
}
```

## Files to Create/Modify
- internal/types/id_generator.go (new)
- internal/storage/sqlite/sqlite.go (CreateIssue)
- internal/storage/sqlite/workspace.go (new - workspace ID management)
- .beads/workspace_id (new file, git-ignored)

## Testing
- Test hash ID generation is deterministic
- Test collision detection and retry
- Test workspace ID persistence
- Benchmark: hash generation performance (<1μs)

GH#505: Add bd reset/wipe command

Add command to cleanly reset/wipe beads database. User reports painful manual process to start fresh. See GitHub issue #505.


Run bd doctor at end of bd init to verify setup

Add WaitGroup tracking to FileWatcher goroutines

FileWatcher spawns goroutines without WaitGroup tracking, causing race condition on shutdown.

Location: cmd/bd/daemon_watcher.go:123-182, 215-291

Problem:
- Goroutines spawned without sync.WaitGroup
- Close() cancels context but doesn't wait for goroutines to exit
- Race condition: goroutine may access fw.debouncer during Close() cleanup
- No guarantee goroutine stopped before fw.watcher.Close() is called

Solution:
- Add sync.WaitGroup field to FileWatcher
- Track goroutines with wg.Add(1) and defer wg.Done()
- Call wg.Wait() in Close() before cleanup

Impact: Race condition on daemon shutdown; potential panic

Effort: 2 hours


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


Centralize error handling patterns in storage layer

80+ instances of inconsistent error handling across sqlite.go with mix of %w, %v, and no wrapping.

Location: internal/storage/sqlite/sqlite.go (throughout)

Problem:
- Some use fmt.Errorf("op failed: %w", err) - correct wrapping
- Some use fmt.Errorf("op failed: %v", err) - loses error chain
- Some return err directly - no context
- Hard to debug production issues
- Can't distinguish error types

Solution: Create internal/storage/sqlite/errors.go:
- Define sentinel errors (ErrNotFound, ErrInvalidID, etc.)
- Create wrapDBError(op string, err error) helper
- Convert sql.ErrNoRows to ErrNotFound
- Always wrap with operation context

Impact: Lost error context; inconsistent messages; hard to debug

Effort: 5-7 hours


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.


Improve test coverage for internal/syncbranch (33.0% → 70%)

The syncbranch package has only 33.0% test coverage. This package handles git sync operations and is critical for data integrity.

Current coverage: 33.0%
Target coverage: 70%


bd import auto-detects wrong prefix from directory name instead of issue IDs

When importing issues.jsonl into a fresh database, 'bd import' prints:

  ✓ Initialized database with prefix 'beads' (detected from issues)

But the issues all have prefix 'bd-' (e.g., bd-03r). It appears to be detecting the prefix from the directory name (.beads/) rather than from the actual issue IDs in the JSONL.

This causes import to fail with:
  validate ID prefix for bd-03r: issue ID 'bd-03r' does not match configured prefix 'beads'

Workaround: Run 'bd config set issue_prefix bd' before import, or use 'bd init --prefix bd'.


Support separate branch for beads commits

Allow beads to commit to a separate branch (e.g., beads-metadata) using git worktrees to support protected main branch workflows.

Solves GitHub Issue #205 - Users need to protect main branch while maintaining beads workflow.

Key advantages:
- Works on any git platform
- Main branch stays protected
- No disruption to user's working directory
- Backward compatible (opt-in via config)
- Minimal disk overhead (sparse checkout)

Total estimate: 17-24 days (4-6 weeks with parallel work)


Test issue 2


Create npm package structure with package.json

Set up initial npm package structure for @beads/bd:

## Files to create
- npm/package.json - Package metadata, dependencies, scripts
- npm/bin/bd - CLI wrapper script that invokes native binary
- npm/.gitignore - Ignore downloaded binaries
- npm/README.md - Installation and usage instructions

## package.json structure
- Name: @beads/bd (scoped package)
- Main: index.js (exports binary path)
- Bin: bin/bd (CLI entry point)
- Scripts: postinstall (download binary)
- Keywords: issue-tracker, cli, beads, bd
- License: MIT

## Bin wrapper
Simple Node.js script that:
- Spawns native binary with child_process.spawn
- Passes through all arguments and stdio
- Exits with binary's exit code


Fix dependency naming inconsistencies (GH #440)

Parent-child dependency documentation is backwards and UI labels are confusing.\n\nProblems:\n1. DEPENDENCIES.md says 'bd dep add PARENT CHILD' but this is rejected\n2. bd show displays epic children under 'Blocks' instead of 'Children'\n3. bd dep tree EPIC shows nothing (need --direction=up)\n4. Inconsistent with 'bd epic status' which uses 'children'\n\nSee: https://github.com/steveyegge/beads/issues/440


Fragile no-db detection uses strings.Contains instead of YAML parsing

Two locations use `strings.Contains(string(configData), "no-db: true")` to detect JSONL-only mode:

1. **cmd/bd/main.go:310** - Auto-enabling no-db mode
2. **cmd/bd/doctor.go:863** - Database status check

This is fragile because it could match:
- Comments: `# no-db: true for testing`
- Nested keys: `settings:\n  no-db: true`
- String values: `note: "set no-db: true to disable"`

Should use proper YAML parsing like we did for sync-branch in bd-0rh:

```go
type noDbConfig struct {
    NoDb bool `yaml:"no-db"`
}

var cfg noDbConfig
if err := yaml.Unmarshal(configData, &cfg); err == nil {
    isNoDbMode = cfg.NoDb
}
```

Improve integration test coverage for stateful features


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.


Create backup and restore procedures

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.


Polecats get stuck on interactive shell prompts (cp/mv/rm -i)

During swarm operations, polecats frequently get stuck waiting for interactive prompts from shell commands like:
- cp prompting 'overwrite file? (y/n)'
- mv prompting 'overwrite file? (y/n)'
- rm prompting 'remove file?'

This happens because macOS aliases or shell configs may have -i flags set by default.

Root cause: Claude Code runs commands that trigger interactive confirmation prompts, but cannot respond to them, causing the agent to hang indefinitely.

Observed in: Multiple polecats during GH issues swarm (Dec 2024)
- Derrick, Roustabout, Prospector, Warboy all got stuck on y/n prompts

Suggested fixes:
1. AGENTS.md should instruct agents to always use -f flag with cp/mv/rm
2. Polecat startup could set shell aliases to use non-interactive versions
3. bd prime hook could include guidance about non-interactive commands
4. Consider detecting stuck prompts and auto-recovering


Update MCP server for hash IDs

Update beads-mcp server to support hash IDs and aliases.

## Changes Needed

### 1. MCP Function Signatures (No Change)
Functions already use issue IDs as strings, so they work with hash IDs:

```python
# These already work!
beads_show(issue_id: str)           # Accepts bd-af78e9a2 or #42
beads_update(issue_id: str, ...)    # Accepts both formats
beads_close(issue_ids: List[str])   # Accepts both formats
```

### 2. Add Alias Resolution Helper
File: integrations/beads-mcp/src/beads_mcp/server.py

```python
def resolve_issue_id(issue_id: str) -> str:
    """Resolve alias to hash ID if needed."""
    # Hash ID: pass through
    if issue_id.startswith('bd-') and len(issue_id) == 11:
        return issue_id

    # Alias: #42 or 42
    alias_str = issue_id.lstrip('#')
    try:
        alias = int(alias_str)
        # Call bd to resolve
        result = subprocess.run(
            ['bd', 'alias', 'find', f'bd-{alias}'],
            capture_output=True, text=True
        )
        if result.returncode == 0:
            return result.stdout.strip()
    except ValueError:
        pass

    # Invalid format
    raise ValueError(f"Invalid issue ID: {issue_id}")
```

### 3. Update Response Formatting
Show aliases in responses:

```python
@server.call_tool()
async def beads_show(issue_id: str) -> List[TextContent]:
    resolved_id = resolve_issue_id(issue_id)

    result = subprocess.run(['bd', 'show', resolved_id], ...)

    # Parse response and add alias info
    # Format: "bd-af78e9a2 (alias: #42)"
    ...
```

### 4. Add beads_alias_* Functions

```python
@server.call_tool()
async def beads_alias_list() -> List[TextContent]:
    """List all alias mappings."""
    result = subprocess.run(['bd', 'alias', 'list'], ...)
    return [TextContent(type="text", text=result.stdout)]

@server.call_tool()
async def beads_alias_set(alias: int, issue_id: str) -> List[TextContent]:
    """Manually assign alias to issue."""
    result = subprocess.run(['bd', 'alias', 'set', str(alias), issue_id], ...)
    return [TextContent(type="text", text=result.stdout)]

@server.call_tool()
async def beads_alias_compact() -> List[TextContent]:
    """Compact aliases to fill gaps."""
    result = subprocess.run(['bd', 'alias', 'compact'], ...)
    return [TextContent(type="text", text=result.stdout)]
```

### 5. Update Documentation
File: integrations/beads-mcp/README.md

```markdown
## Issue IDs (v2.0+)

The MCP server accepts both hash IDs and aliases:

```python
# Using hash IDs
await beads_show(issue_id="bd-af78e9a2")

# Using aliases
await beads_show(issue_id="#42")
await beads_show(issue_id="42")  # Shorthand
```

## Alias Management

New functions for alias control:

- `beads_alias_list()` - List all alias mappings
- `beads_alias_set(alias, issue_id)` - Manually assign alias
- `beads_alias_compact()` - Compact aliases to fill gaps

## Migration

After migrating to hash IDs:
1. Update beads-mcp: `pip install --upgrade beads-mcp`
2. Restart MCP server
3. All existing workflows continue to work
```

### 6. Version Compatibility
Detect and handle both v1.x and v2.0 formats:

```python
def detect_beads_version() -> str:
    """Detect if beads is using sequential or hash IDs."""
    result = subprocess.run(['bd', 'list', '-n', '1'], ...)
    first_id = parse_first_issue_id(result.stdout)

    if first_id.startswith('bd-') and len(first_id) > 11:
        return '2.0'  # Hash ID
    else:
        return '1.x'  # Sequential ID

# On startup
beads_version = detect_beads_version()
logger.info(f"Detected beads version: {beads_version}")
```

## Testing

### Unit Tests
File: integrations/beads-mcp/tests/test_hash_ids.py

```python
def test_resolve_hash_id():
    """Hash IDs pass through unchanged."""
    assert resolve_issue_id("bd-af78e9a2") == "bd-af78e9a2"

def test_resolve_alias():
    """Aliases resolve to hash IDs."""
    # Mock bd alias find command
    assert resolve_issue_id("#42") == "bd-af78e9a2"
    assert resolve_issue_id("42") == "bd-af78e9a2"

def test_invalid_id():
    """Invalid IDs raise ValueError."""
    with pytest.raises(ValueError):
        resolve_issue_id("invalid")
```

### Integration Tests
```python
async def test_show_with_hash_id(mcp_server):
    result = await mcp_server.beads_show(issue_id="bd-af78e9a2")
    assert "bd-af78e9a2" in result[0].text

async def test_show_with_alias(mcp_server):
    result = await mcp_server.beads_show(issue_id="#42")
    assert "bd-af78e9a2" in result[0].text  # Resolved
```

## Backward Compatibility
The MCP server should work with both:
- Beads v1.x (sequential IDs)
- Beads v2.0+ (hash IDs)

Detection happens at runtime based on issue ID format.

## Files to Modify
- integrations/beads-mcp/src/beads_mcp/server.py
- integrations/beads-mcp/README.md
- integrations/beads-mcp/tests/test_hash_ids.py (new)
- integrations/beads-mcp/pyproject.toml (bump version)

## Deployment
```bash
cd integrations/beads-mcp
# Bump version to 2.0.0
poetry version 2.0.0
# Publish to PyPI
poetry publish --build
```


Use TryResurrectParentChain instead of TryResurrectParent in GetNextChildID

## Context
Current bd-dvd fix uses TryResurrectParent, which only resurrects the immediate parent. For deeply nested hierarchies, this might not be sufficient.

## Example Scenario
Creating child with parent "bd-abc.1.2" where:
- bd-abc exists in DB
- bd-abc.1 was deleted (missing from DB, exists in JSONL)
- bd-abc.1.2 was deleted (missing from DB, exists in JSONL)

Current fix: Only tries to resurrect "bd-abc.1.2", fails because its parent "bd-abc.1" is missing.

## Solution
Replace TryResurrectParent with TryResurrectParentChain:

```go
if count == 0 {
    // Try to resurrect entire parent chain from JSONL history (bd-dvd fix)
    // This handles deeply nested hierarchies where intermediate parents are also missing
    resurrected, err := s.TryResurrectParentChain(ctx, parentID)
    if err != nil {
        return "", fmt.Errorf("failed to resurrect parent chain for %s: %w", parentID, err)
    }
    if !resurrected {
        return "", fmt.Errorf("parent issue %s does not exist and could not be resurrected from JSONL history", parentID)
    }
}
```

## Investigation
- Check if this scenario actually happens in practice
- TryResurrectParentChain already exists (resurrection.go:174-209)
- May be overkill if users always create parents before children

## Files
- internal/storage/sqlite/hash_ids.go

## Testing
Add test case for deeply nested resurrection


Benchmark Suite for Critical Operations

Extend existing benchmark suite with comprehensive benchmarks for critical operations at 10K-20K scale.

Existing benchmarks (keep these):
- cycle_bench_test.go - Cycle detection up to 5K issues (linear, tree, dense graphs)
- compact_bench_test.go - Compaction candidate queries (100 issues)
- internal/rpc/bench_test.go - Daemon vs direct mode comparison

New benchmarks to add in sqlite_bench_test.go (~10-12 total):
1. GetReadyWork - Simple, deep hierarchies, cross-linked (CRITICAL - not currently benchmarked)
2. SearchIssues - No filters, complex filters (CRITICAL - not currently benchmarked)
3. CreateIssue - Single issue creation
4. UpdateIssue - Status/priority/assignee changes
5. AddDependency - Extend to 10K/20K scale (currently only up to 5K)
6. JSONL Export - Full export performance
7. JSONL Import - Import performance

Scale levels:
- Large: 10K issues (5K open, 5K closed)
- XLarge: 20K issues (10K open, 10K closed)

Implementation:
- NEW FILE: internal/storage/sqlite/sqlite_bench_test.go
- Keep existing cycle_bench_test.go and compact_bench_test.go unchanged
- Build tag: //go:build bench
- Standard testing.B benchmarks
- b.ReportAllocs() for memory tracking
- Test both SQLite and JSONL-imported databases

Always generates CPU and memory profiles for analysis.


Add bd init --team wizard

Interactive wizard for team workflow setup. Guides user through: branch workflow configuration, shared repo setup, team member onboarding, examples of team collaboration patterns.


Review and document rarely-used commands

Document use cases or consider deprecation for infrequently-used commands.

**Commands to review:**
1. bd rename-prefix - How often is this used? Document use cases
2. bd detect-pollution - Consider integrating into bd validate
3. bd migrate-hash-ids - One-time migration, keep but document as legacy

**For each command:**
- Document typical use cases
- Add examples to help text
- Consider if it should be a subcommand instead
- Add deprecation warning if appropriate

**Not changing:**
- duplicates ✓ (useful for data quality)
- repair-deps ✓ (useful for fixing broken refs)
- restore ✓ (critical for compacted issues)
- compact ✓ (performance feature)

**Deliverable:**
- Updated help text
- Documentation in ADVANCED.md
- Deprecation plan if needed


GH#509: bd doesn't find .beads when running from nested worktrees

When worktrees are nested under main repo (.worktrees/feature/), bd stops at worktree git root instead of continuing to find .beads in parent. See GitHub issue #509 for detailed fix suggestion.


Auto-import runs during --no-auto-import operations via stats/ready commands

Even when using --no-auto-import flag, certain commands like 'bd stats' and 'bd ready' still trigger auto-import internally, which can cause the git history backfill bug to corrupt data.

Example:
  bd stats --no-auto-import
  # Still prints 'Purged bd-xxx (recovered from git history...)'

The flag should completely disable auto-import for the command, but it appears some code paths still trigger it.

Workaround: Use --allow-stale instead, or --sandbox mode.


bd cleanup fails with CHECK constraint on status/closed_at mismatch

## Problem

Running `bd cleanup --force` fails with:

```
Error: failed to create tombstone for bd-okh: sqlite3: constraint failed: CHECK constraint failed: (status = 'closed') = (closed_at IS NOT NULL)
```

## Root Cause

The database has a CHECK constraint ensuring closed issues have `closed_at` set and non-closed issues don't. When `bd cleanup` tries to convert a closed issue to a tombstone, this constraint fails if:
1. The issue has status='closed' but closed_at is NULL, OR
2. The issue is being converted but the tombstone creation doesn't properly handle the closed_at field

## Impact

- `bd cleanup --force` cannot complete
- 722 closed issues cannot be cleaned up
- Blocks routine maintenance

## Investigation Needed

1. Check the bd-okh record in the database:
   ```sql
   SELECT id, status, closed_at, deleted_at FROM issues WHERE id = 'bd-okh';
   ```
2. Determine if this is data corruption or a bug in tombstone creation

## Proposed Solutions

1. **If data corruption**: Add a `bd doctor --fix` check that repairs status/closed_at mismatches
2. **If code bug**: Fix the tombstone creation to properly handle the constraint

## Files to Investigate

- `internal/storage/sqlite/sqlite.go` - DeleteIssue / tombstone creation
- Schema CHECK constraint definition

## Acceptance Criteria

- [ ] Identify root cause (data vs code bug)
- [ ] `bd cleanup --force` completes successfully
- [ ] `bd doctor` detects status/closed_at mismatches


Missing test: base is tombstone, both left and right are live

The tombstone merge tests do not cover the case where the base version is a tombstone but both left and right have resurrected/live versions. This scenario could occur if: 1) Clone A deletes an issue, 2) Clone B and Clone C both sync from A (getting tombstone), 3) Both B and C independently recreate an issue with same ID. The current code would likely fall through to standard mergeIssue() which may not be correct. Need to add test and verify behavior. Files: internal/merge/merge_test.go, internal/merge/merge.go:347-387


Add AI planning docs management guidance to bd onboard (GH-196)

Enhanced bd onboard command to provide guidance for managing AI-generated planning documents (Claude slop).

Addresses GitHub issue #196: https://github.com/steveyegge/beads/issues/196

Changes:
- Added Managing AI-Generated Planning Documents section to bd onboard
- Recommends using history/ directory for ephemeral planning files
- Updated AGENTS.md to demonstrate the pattern
- Added comprehensive tests

Commit: d46177d


isLikelyHash rejects 3-char all-letter base36 hashes

ExtractIssuePrefix fails for multi-hyphen prefixes when the 3-char hash suffix has no digits.

Example: `xa-adt-bat` returns prefix `xa` instead of `xa-adt`.

Root cause: `isLikelyHash()` requires at least one digit to distinguish hashes from English words, but base36 hashes can be all-letters by chance.

Affected: 20 issues in xa-adapt with suffixes like bat, dev, fbi, oil, etc.


Support P-prefix priority format (P0-P4) in create and update commands


Improve clean vs cleanup command naming/documentation

Clarify the difference between bd clean and bd cleanup to reduce user confusion.

**Current state:**
- bd clean: Remove temporary artifacts (.beads/bd.sock, logs, etc.)
- bd cleanup: Delete old closed issues from database

**Options:**
1. Rename for clarity:
   - bd clean → bd clean-temp
   - bd cleanup → bd cleanup-issues

2. Keep names but improve help text and documentation

3. Add prominent warnings in help output

**Preferred approach:** Option 2 (improve documentation)
- Update short/long descriptions in commands
- Add examples to help text
- Update README.md
- Add cross-references in help output

**Files to modify:**
- cmd/bd/clean.go
- cmd/bd/cleanup.go
- README.md or ADVANCED.md


Refactor daemon.go into internal/daemonrunner

Extract daemon runtime from daemon.go (1,565 lines) into internal/daemonrunner with focused modules: config.go, daemon.go, process.go, rpc_server.go, sync.go, git.go. Keep cobra command thin.


CRITICAL: bd sync exports before pull, allowing stale DB to corrupt JSONL statuses

## Root Cause

The fix in bd-53c (reverse ZFC check) only checks COUNTS, not content. The real corruption happens when:

1. Polecat A has stale DB with old status values (e.g., status=closed for issues that are now open on remote)
2. Polecat A runs bd sync:
   - **Export FIRST**: DB (status=closed) → JSONL (overwrites correct status=open)
   - Commit: Stale JSONL committed
   - Pull: 3-way merge with remote
   - Merge uses 'closed wins' rule → status stays closed
3. Polecat A pushes → Remote now corrupted with status=closed

## Why bd-53c didn't fix it

The reverse ZFC check compares COUNTS:
```go
if jsonlCount > dbCount  // Only catches count mismatch
```

But in the corruption scenario:
- JSONL count = 5, DB count = 5 (same count!)
- Only the STATUS field differs

## The Real Fix

**PULL BEFORE EXPORT**. The sync order must be:
1. Pull from remote (get latest state)
2. Import merged JSONL to DB
3. THEN export DB changes (if any)

Current order is: Export → Commit → Pull → Import → Push

This is a fundamental architecture change to the sync flow.

## Workaround

Use --no-auto-flush and manually control the sync order, or disable daemon auto-export.

## Evidence

From user investigation:
- At 595b7943 (13:20:30): 5 open issues
- At 10239812 (13:28:39): 0 open issues
- All 5 issues had their status changed from open to closed
- Count stayed at 5 (not a deletion issue)


Add bd hooks install command to embed git hooks in binary

Currently git hooks are installed via `examples/git-hooks/install.sh`, which only exists in the beads source repo. Users who install bd via installer/homebrew/npm can't easily install hooks.

**Proposal:**
Add `bd hooks install` command that:
- Embeds hook scripts in the bd binary (using go:embed)
- Installs them to .git/hooks/ in current repo
- Backs up existing hooks
- Makes them executable

**Commands:**
- `bd hooks install` - Install all hooks
- `bd hooks uninstall` - Remove hooks
- `bd hooks list` - Show installed hooks status

**Benefits:**
- Works for all bd users, not just source repo users
- More discoverable (shows in bd --help)
- Consistent with bd workflow
- Can version hooks with bd releases


Inconsistent stderr printing: bd-feh warning still prints directly


Improve test coverage for internal/lockfile (42.0% → 60%)

The lockfile package has only 42.0% test coverage. Lock file handling is critical for preventing data corruption in concurrent scenarios.

Current coverage: 42.0%
Target coverage: 60%


Issue 2 to reopen


Add 'bd status' command for issue database overview

Implement a bd status command that provides a quick snapshot of the issue database state, similar to how git status shows working tree state.

Expected output: Show summary including counts by state (open, in-progress, blocked, closed), recent activity (last 7 days), and quick overview without needing multiple queries.

Example output showing issue counts, recent activity stats, and pointer to bd list for details.

Proposed options: --all (show all issues), --assigned (show issues assigned to current user), --json (JSON format output)

Use cases: Quick project health check, onboarding for new contributors, integration with shell prompts or CI/CD, daily standup reference


Client self-heal: remove stale pid when lock free + socket missing

When client detects:
- Socket is missing AND
- tryDaemonLock shows lock NOT held

Then automatically:
1. Remove stale daemon.pid file
2. Optionally auto-start daemon (behind BEADS_AUTO_START_DAEMON=1 env var)

This prevents stale artifacts from accumulating after daemon crashes.


Dogfood: Migrate beads repo to hash IDs

Final validation: migrate the beads project itself to hash-based IDs.

## Purpose
Dogfooding the migration on beads' own issue database to:
1. Validate migration tool works on real data
2. Discover edge cases
3. Verify all workflows still work
4. Build confidence for users

## Beads v2.0 Released: Hash-Based IDs

We've migrated beads to hash-based IDs! 🎉

**What changed:**
- Issues now use hash IDs (bd-af78e9a2) instead of sequential (bd-cb64c226.3)
- Human-friendly aliases (#42) for easy reference
- Zero collision risk in distributed workflows

**Action required:**
If you have a local clone, you need to migrate:

GH#403: bd doctor --fix circular error message

bd doctor --fix suggests running bd doctor --fix for deletions manifest issue. Fix to provide actual resolution. See GitHub issue #403.


Handle unchecked errors (errcheck - 683 issues)

683 unchecked error returns, mostly in tests (Close, Rollback, RemoveAll). Many already excluded in config but still showing up.

Fixed all errcheck warnings in production code:
- Enabled errcheck linter (was disabled)
- Set tests: false in .golangci.yml to focus on production code
- Fixed 27 total errors in production code using Oracle guidance:
  * Database patterns: defer func() { _ = rows.Close() }() and defer func() { _ = tx.Rollback() }()
  * Best-effort closers: _ = store.Close(), _ = client.Close()
  * Proper error handling for file writes, fmt.Scanln(), os.Remove()
- All tests pass
- Only 2 "unused" linter warnings remain (not errcheck)


GetNextChildID doesn't attempt parent resurrection from JSONL history

When creating a child issue with --parent flag, GetNextChildID fails immediately if parent doesn't exist in DB, without attempting to resurrect it from JSONL history. This breaks the intended resurrection workflow and causes 'parent issue X does not exist' errors even when the parent exists in JSONL.

Related to GH #334 and #278.

Current behavior:
- GetNextChildID checks if parent exists in DB
- If not found, returns error immediately
- No resurrection attempt

Expected behavior:
- GetNextChildID should call TryResurrectParent before failing
- Parent should be restored as tombstone if found in JSONL history
- Child creation should succeed if resurrection succeeds

Impact: Users cannot create child issues for parents that were deleted but exist in JSONL history.


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.


Import overwrites newer local issues with older remote versions

## Problem

During git pull + import, local issues with newer updated_at timestamps get overwritten by older versions from remote JSONL.

## What Happened

Timeline:
1. 17:52 - Closed bd-df190564 and bd-b501fcc1 locally (updated_at: 2025-10-31)
2. 17:51 - Remote pushed same issues with status=open (updated_at: 2025-10-30)
3. 17:52 - Local sync pulled remote commit and imported JSONL
4. Result: Issues reverted to open despite local version being newer

## Root Cause

DetectCollisions (internal/storage/sqlite/collision.go:67-79) compares fields but doesn't check timestamps:

```go
conflictingFields := compareIssues(existing, incoming)
if len(conflictingFields) == 0 {
    result.ExactMatches = append(result.ExactMatches, incoming.ID)
} else {
    // Same ID, different content - treats as UPDATE
    result.Collisions = append(result.Collisions, &CollisionDetail{...})
}
```

Import applies incoming version regardless of which is newer.

## Expected Behavior

Import should:
1. Compare updated_at timestamps when collision detected
2. Skip update if local version is newer
3. Apply update only if remote version is newer
4. Warn on timestamp conflicts

## Solution

Add timestamp checking to DetectCollisions or importIssues:

```go
if len(conflictingFields) > 0 {
    // Check timestamps
    if !incoming.UpdatedAt.After(existing.UpdatedAt) {
        // Local is newer or same - skip update
        result.ExactMatches = append(result.ExactMatches, incoming.ID)
        continue
    }
    // Remote is newer - apply update
    result.Collisions = append(result.Collisions, &CollisionDetail{...})
}
```

Improve test coverage for cmd/bd CLI (26.2% → 50%)

The main CLI package (cmd/bd) has only 26.2% test coverage. CLI commands should have at least 50% coverage to ensure reliability.

Key areas with low/no coverage:
- daemon_autostart.go (multiple 0% functions)
- compact.go (several 0% functions)
- Various command handlers

Current coverage: 26.2%
Target coverage: 50%


Refactor create_test.go to use shared DB setup

Convert TestCreate_* functions to use test suites with shared database setup.

Example transformation:
- Before: 10 separate tests, each with newTestStore()
- After: 1 TestCreate() with 10 t.Run() subtests sharing one DB

Estimated speedup: 10x faster (1 DB setup instead of 10)


Update docs for import bug fix

Update AGENTS.md, README.md, TROUBLESHOOTING.md with import.orphan_handling config documentation. Document resurrection behavior, tombstones, config modes. Add troubleshooting section for import failures with deleted parents.


Research Go WASM compilation and modernc.org/sqlite WASM support

Investigate technical requirements for compiling bd to WASM:
- Verify modernc.org/sqlite has working js/wasm support
- Identify Go stdlib limitations in WASM (syscalls, file I/O, etc.)
- Research wasm_exec.js runtime and Node.js integration
- Document any API differences between native and WASM builds


Add #nosec G304 comments to JSONL file reads in sync.go

sync.go:610 uses os.ReadFile(jsonlPath) without #nosec comment, inconsistent with other JSONL reads that have '// #nosec G304 - controlled path'.

Add comment for consistency with integrity.go:43 and import.go:316.


Debug test 2


Block direct status update to tombstone in UpdateIssue

Per bd-2m7 design: 'Should we support tombstone as valid input to bd update --status? Recommendation: No, tombstones only created via bd delete'

Currently nothing prevents 'bd update <id> --status=tombstone', which would create an invalid tombstone (missing deleted_at, deleted_by, etc.).

Location: internal/storage/sqlite/queries.go:500-664 UpdateIssue

Add validation to reject status=tombstone in updates.


Implement TryResurrectParent function

Create internal/storage/sqlite/resurrection.go with TryResurrectParent(ctx, parentID) function. Parse JSONL history to find deleted parent, create tombstone with status=deleted and is_tombstone=true flag. Handle recursive resurrection for multi-level missing parents (bd-abc.1.2 with missing bd-abc and bd-abc.1).


Update AGENTS.md with event-driven mode

Document BEADS_DAEMON_MODE env var. Explain opt-in during Phase 1. Add troubleshooting for watcher failures.


Implement bd stale command to find abandoned/forgotten issues

Add bd stale command to surface issues that haven't been updated recently and may need attention.

Use cases:
- In-progress issues with no recent activity (may be abandoned)
- Open issues that have been forgotten
- Issues that might be outdated or no longer relevant

Query logic should find non-closed issues where updated_at exceeds a time threshold.

Should support:
- --days N flag (default 30-90 days)
- --status filter (e.g., only in_progress)
- --json output for automation

References GitHub issue #184 where user expected this command to exist.


getLocalSyncBranch silently ignores YAML parse errors

In autoimport.go:170-172, YAML parsing errors are silently ignored. If a user has malformed YAML in config.yaml, sync-branch will just silently be empty with no feedback.

Recommendation: Add debug logging since this function is only called during auto-import, and debugging silent failures is painful.

Add: debug.Logf("Warning: failed to parse config.yaml: %v", err)


Fix G104 errors unhandled in internal/storage/sqlite/queries.go:1181

Linting issue: G104: Errors unhandled (gosec) at internal/storage/sqlite/queries.go:1181:4. Error: rows.Close()


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.


Split test suites: fast vs. integration

Reorganize tests into separate packages/files for fast unit tests vs slow integration tests.

Benefits:
- Clear separation of concerns
- Easier to run just fast tests during development
- Can parallelize CI jobs better

Files to organize:
- beads_hash_multiclone_test.go (slow integration tests)
- beads_integration_test.go (medium-speed integration tests)
- Other test files (fast unit tests)


CRDT-based architecture for guaranteed convergence (v2.0)

## Vision
Redesign beads around Conflict-Free Replicated Data Types (CRDTs) to provide mathematical guarantees for N-way collision resolution at arbitrary scale.

## Current Limitations
- Content-hash based collision resolution fails at 5+ clones
- Non-deterministic convergence in multi-round scenarios
- UNIQUE constraint violations during rename operations
- No formal proof of convergence properties

## CRDT Benefits
- Provably convergent (Strong Eventual Consistency)
- Commutative/Associative/Idempotent operations
- No coordination required between clones
- Scales to 100+ concurrent workers
- Well-understood mathematical foundations

## Proposed Architecture

### 1. UUID-Based IDs
Replace sequential IDs with UUIDs:
- Current: bd-1c63eb84, bd-9063acda, bd-4d80b7b1
- CRDT: bd-a1b2c3d4-e5f6-7890-abcd-ef1234567890
- Human aliases maintained separately: #42 maps to UUID

### 2. Last-Write-Wins (LWW) Elements
Each field becomes an LWW register:
- title: (timestamp, clone_id, value)
- status: (timestamp, clone_id, value)
- Deterministic conflict resolution via Lamport timestamp + clone_id tiebreaker

### 3. Operation Log
Track all operations as CRDT ops:
- CREATE(uuid, timestamp, clone_id, fields)
- UPDATE(uuid, field, timestamp, clone_id, value)
- DELETE(uuid, timestamp, clone_id) - tombstone, not hard delete

### 4. Sync as Merge
Syncing becomes merging two CRDT states:
- No merge conflicts possible
- Deterministic merge function
- Guaranteed convergence

## Implementation Phases

### Phase 1: Research & Design (4 weeks)
- Study existing CRDT implementations (Automerge, Yjs, Loro)
- Design schema for CRDT-based issue tracking
- Prototype LWW-based Issue CRDT
- Benchmark performance vs current system

### Phase 2: Parallel Implementation (6 weeks)
- Implement CRDT storage layer alongside SQLite
- Build conversion tools: SQLite ↔ CRDT
- Maintain backward compatibility with v1.x format
- Migration path for existing databases

### Phase 3: Testing & Validation (4 weeks)
- Formal verification of convergence properties
- Stress testing with 100+ clone scenario
- Performance profiling and optimization
- Documentation and examples

### Phase 4: Migration & Rollout (4 weeks)
- Release v2.0-beta with CRDT backend
- Gradual migration from v1.x
- Monitoring and bug fixes
- Final v2.0 release

## Risks & Mitigations

**Risk 1: Performance overhead**
- Mitigation: Benchmark early, optimize hot paths
- CRDTs can be slower than append-only logs
- May need compaction strategy

**Risk 2: Storage bloat**
- Mitigation: Implement operation log compaction
- Tombstone garbage collection for deleted issues
- Periodic snapshots to reduce log size

**Risk 3: Breaking changes**
- Mitigation: Maintain v1.x compatibility layer
- Gradual migration tools
- Dual-mode operation during transition

**Risk 4: Complexity**
- Mitigation: Use battle-tested CRDT libraries
- Comprehensive documentation
- Clear migration guide

## Success Criteria
- 100-clone collision test passes without failures
- Formal proof of convergence properties
- Performance within 2x of current system
- Zero manual conflict resolution required
- Backward compatible with v1.x databases

## Timeline
18-20 weeks total (4-5 months)

bd init overwrites existing git hooks without detection or chaining

GH #254: bd init silently overwrites existing git hooks (like pre-commit framework) without detecting them, backing them up, or offering to chain. This breaks workflows and can result in committed code with failing tests.

Fix: Detect existing hooks, prompt user with options to chain/overwrite/skip.


bd doctor --fix needs non-interactive mode (-y/--yes flag)

When running `bd doctor --fix` in non-interactive mode (scripts, CI, Claude Code), it prompts 'Continue? (Y/n):' and fails with EOF.

**Expected**: A `-y` or `--yes` flag to auto-confirm fixes.

**Workaround**: Currently have to run `bd init` instead, but that's not discoverable from the doctor output.


bd doctor should recommend bd prime migration for existing repos

bd doctor should detect old beads integration patterns and recommend migrating to bd prime approach.

## Current behavior
- bd doctor checks if Claude hooks are installed globally
- Doesn't check project-level integration (AGENTS.md, CLAUDE.md)
- Doesn't recommend migration for repos using old patterns

## Desired behavior
bd doctor should detect and suggest:

1. **Old slash command pattern detected**
   - Check for /beads:* references in AGENTS.md, CLAUDE.md
   - Suggest: These slash commands are deprecated, use bd prime hooks instead

2. **No agent documentation**
   - Check if AGENTS.md or CLAUDE.md exists
   - Suggest: Run 'bd onboard' or 'bd setup claude' to document workflow

3. **Old MCP-only pattern**
   - Check for instructions to use MCP tools but no bd prime hooks
   - Suggest: Add bd prime hooks for better token efficiency

4. **Migration path**
   - Show: 'Run bd setup claude to add SessionStart/PreCompact hooks'
   - Show: 'Update AGENTS.md to reference bd prime instead of slash commands'

## Example output

⚠ Warning: Old beads integration detected in CLAUDE.md
  Found: /beads:* slash command references (deprecated)
  Recommend: Migrate to bd prime hooks for better token efficiency
  Fix: Run 'bd setup claude' and update CLAUDE.md

💡 Tip: bd prime + hooks reduces token usage by 80-99% vs slash commands
  MCP mode: ~50 tokens vs ~10.5k for full MCP scan
  CLI mode: ~1-2k tokens with automatic context recovery

## Benefits
- Helps existing repos adopt new best practices
- Clear migration path for users
- Better token efficiency messaging


Add tests for Comments API (AddIssueComment, GetIssueComments)

Comments API currently has 0% coverage. Need tests for:
- AddIssueComment - adding comments to issues
- GetIssueComments - retrieving comments
- Comment ordering and pagination
- Edge cases (non-existent issues, empty comments)


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).


Git history fallback missing timeout - could hang on large repos

## Problem

The git commands in `checkGitHistoryForDeletions` have no timeout. On large repos with extensive history, `git log --all -S` or `git log --all -G` can take a very long time (minutes).

## Location
`internal/importer/importer.go:899` and `:930`

## Impact
- Import could hang indefinitely
- User has no feedback that git search is running
- No way to cancel except killing the process

## Fix
Add context with timeout to git commands:

```go
ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()
cmd := exec.CommandContext(ctx, "git", ...)
```

Also consider adding a `--since` flag to bound the git history search.


GH#532: bd sync circular error (suggests running bd sync)

bd sync error message recommends running bd sync to fix the bd sync error. Fix error handling to provide useful guidance. See GitHub issue #532.


Implement auto-merge functionality in duplicates command

The duplicates.go file has a TODO at line 95 to implement the performMerge function for automatic duplicate merging. Currently it just prints a warning message. This would automate the merge process instead of just suggesting commands.


CRITICAL: git-history-backfill purges entire database when JSONL reset

When a clone gets reset (git reset --hard origin/main), the git-history-backfill logic incorrectly adds ALL issues to the deletions manifest, then sync purges the entire database.\n\nFix adds safety guard: never delete more than 50% of issues via git-history-backfill. If threshold exceeded, abort with warning message.


Refactor cmd/bd/daemon.go for testability and maintainability


Add global verbosity flags (--verbose, --quiet)

Add consistent verbosity controls across all commands.

**Current state:**
- bd init has --quiet flag
- No other commands have verbosity controls
- Debug output controlled by BD_VERBOSE env var

**Proposal:**
Add persistent flags:
- --verbose / -v: Enable debug output
- --quiet / -q: Suppress non-essential output

**Implementation:**
- Add to rootCmd.PersistentFlags()
- Replace BD_VERBOSE checks with flag checks
- Standardize output levels:
  * Quiet: Errors only
  * Normal: Errors + success messages
  * Verbose: Errors + success + debug info

**Files to modify:**
- cmd/bd/main.go (add flags)
- internal/debug/debug.go (respect flags)
- Update all commands to respect quiet mode

**Testing:**
- Verify --verbose shows debug output
- Verify --quiet suppresses normal output
- Ensure errors always show regardless of mode

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


Fix gosec lint warnings in doctor.go, main.go, and fix subdirectory

CI lint job failing with 4 gosec warnings:
- cmd/bd/doctor.go:664 (G304: file inclusion via variable)
- cmd/bd/doctor/fix/database_config.go:166 (G304: file inclusion via variable)
- cmd/bd/doctor/fix/untracked.go:61 (G204: subprocess launched with variable)
- cmd/bd/main.go:645 (G304: file inclusion via variable)

Either suppress with `// #nosec` if false positives, or refactor to validate paths properly.


Improve sync error messages

When bd sync fails, immediately surface the actual root cause (prefix mismatch, orphaned children, forced push detected, etc.) instead of requiring multiple retries to discover it. Make errors actionable with specific recovery steps.


deletions.jsonl recreated locally after tombstone migration

After running bd migrate-tombstones and removing deletions.jsonl from git, the file gets recreated locally on subsequent bd commands.

**Steps to reproduce:**
1. Run bd migrate-tombstones (converts to inline tombstones)
2. Remove deletions.jsonl from git and filesystem
3. Run bd sync or bd stats
4. deletions.jsonl reappears

**Expected behavior:**
After migration, deletions.jsonl should not be recreated. All tombstone data should come from inline tombstones in issues.jsonl.

**Workaround:** Add deletions.jsonl to .gitignore to prevent re-tracking. File still gets created but won't pollute the repo.


Implement postinstall script for binary download

Create npm/scripts/postinstall.js that downloads platform-specific binaries:

## Platform detection
- Detect os.platform() and os.arch()
- Map to GitHub release asset names:
  - linux-amd64 → bd-linux-amd64
  - linux-arm64 → bd-linux-arm64
  - darwin-amd64 → bd-darwin-amd64
  - darwin-arm64 → bd-darwin-arm64
  - win32-x64 → bd-windows-amd64.exe

## Download logic
- Fetch from GitHub releases: https://github.com/steveyegge/beads/releases/latest/download/${asset}
- Save to npm/bin/bd (or bd.exe on Windows)
- Set executable permissions (chmod +x)
- Handle errors gracefully with helpful messages

## Error handling
- Check for unsupported platforms
- Retry on network failures
- Provide manual download instructions if automated fails
- Skip download if binary already exists (for local development)


Issue 1 to reopen


Extract duplicated metadata update code in daemon_sync.go

## Problem
The same 22-line metadata update block appears identically in both:
- createExportFunc (lines 309-328)
- createSyncFunc (lines 520-539)

This violates DRY principle and makes maintenance harder.

## Solution
Extract to helper function:

```go
// updateExportMetadata updates last_import_hash and related metadata after a successful export.
// This prevents "JSONL content has changed since last import" errors on subsequent exports (bd-ymj fix).
func updateExportMetadata(ctx context.Context, store storage.Storage, jsonlPath string, log daemonLogger) {
    currentHash, err := computeJSONLHash(jsonlPath)
    if err != nil {
        log.log("Warning: failed to compute JSONL hash for metadata update: %v", err)
        return
    }

    if err := store.SetMetadata(ctx, "last_import_hash", currentHash); err != nil {
        log.log("Warning: failed to update last_import_hash: %v", err)
    }

    exportTime := time.Now().Format(time.RFC3339)
    if err := store.SetMetadata(ctx, "last_import_time", exportTime); err != nil {
        log.log("Warning: failed to update last_import_time: %v", err)
    }

    // Store mtime for fast-path optimization
    if jsonlInfo, statErr := os.Stat(jsonlPath); statErr == nil {
        mtimeStr := fmt.Sprintf("%d", jsonlInfo.ModTime().Unix())
        if err := store.SetMetadata(ctx, "last_import_mtime", mtimeStr); err != nil {
            log.log("Warning: failed to update last_import_mtime: %v", err)
        }
    }
}
```

Add tests for 3-way merge scenarios

Comprehensive test coverage for merge logic.

**Test cases**:
- Simple field updates (left vs right)
- Dependency merging (union + dedup)
- Timestamp handling (max wins)
- Deletion detection (deleted in one, modified in other)
- Conflict generation (incompatible changes)
- Issue resurrection prevention (bd-hv01 regression test)

Refactor sqlite.go into focused modules

Split sqlite.go (2,298 lines) into focused modules: migrations.go, ids.go, issues.go, events.go, dirty.go, db.go. This will improve maintainability and reduce cognitive load.


bd sync: use worktree for sync.branch commits (non-daemon mode)

## Summary

When `sync.branch` is configured (e.g., `beads-sync`), `bd sync` should commit beads changes to that branch via git worktree, even when the user's working directory is on a different branch (e.g., `main`).

Currently:
- `bd sync` always commits to the current branch
- Daemon with `--auto-commit` uses worktrees to commit to sync branch
- Gap: `bd sync` ignores sync.branch config

## Goal

Workers stay on `main` (or feature branches) while beads metadata automatically flows to `beads-sync` branch. No daemon required.

## Design Considerations

1. **Worktree lifecycle**: Create on first use, reuse thereafter
2. **Daemon interaction**: Ensure daemon and bd sync don't conflict
3. **MCP server**: Uses daemon or direct mode - needs same behavior
4. **Pull semantics**: Pull from sync branch, not current branch
5. **Push semantics**: Push to sync branch remote
6. **Error handling**: Worktree corruption, missing branch, etc.

## Affected Components

- `cmd/bd/sync.go` - Main changes
- `cmd/bd/daemon_sync_branch.go` - Reuse existing functions
- `internal/git/worktree.go` - Already implemented
- MCP server (if it bypasses daemon)

## Edge Cases

- Fresh clone (no sync branch exists yet)
- Worktree exists but is corrupted
- Concurrent bd sync from multiple processes
- sync.branch configured but remote doesn't have that branch
- User switches sync.branch config mid-session


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.


Improve cmd/bd test coverage from 21% to 40% (multi-session effort)

Current coverage: 21.0% of statements in cmd/bd
Target: 40%
This is a multi-session incremental effort.

Focus areas:
- Command handler tests (create, update, close, list, etc.)
- Flag validation and error cases
- JSON output formatting
- Edge cases and error handling

Track progress with 'go test -cover ./cmd/bd'

Coverage improved from 21% to 27.4% (package) and 42.9% (total function coverage).

Added tests for:
- compact.go test coverage (eligibility checks, dry run scenarios)
- epic.go test coverage (epic status, children tracking, eligibility for closure)

New test files created:
- epic_test.go (3 test functions covering epic functionality)

Enhanced compact_test.go:
- TestRunCompactSingleDryRun
- TestRunCompactAllDryRun

Total function coverage now at 42.9%, exceeding the 40% target.


Add depth-based batch creation in upsertIssues

Replace single batch creation with depth-level batching (max depth 3). Create issues at depth 0, then 1, then 2, then 3. Prevents parent validation errors when importing hierarchical issues in same batch. File: internal/importer/importer.go:534-546


Add 'bd comment' as alias for 'bd comments add'

The command 'bd comments add' is verbose and unintuitive. Add 'bd comment' as a shorter alias that works the same way.

## Rationale
- More natural: 'bd comment <issue-id> <text>' reads better than 'bd comments add <issue-id> <text>'
- Matches user expectations: users naturally try 'bd comment' first
- Follows convention: other commands like 'bd create', 'bd show', 'bd close' are verbs

## Implementation
Could be implemented as:
1. A new command that wraps bd comments add
2. An alias registered in cobra
3. Keep 'bd comments add' for backwards compatibility

## Examples
```bash
bd comment bd-1234 'This is a comment'
bd comment bd-1234 'Multi-line comment' --body 'Additional details here'
```


Prevent multiple daemons from running on the same repo

Multiple bd daemons running on the same repo clone causes race conditions and data corruption risks.

**Problem:**
- Nothing prevents spawning multiple daemons for the same repository
- Multiple daemons watching the same files can conflict during sync operations
- Observed: 4 daemons running simultaneously caused sync race condition

**Solution:**
Implement daemon singleton enforcement per repo:
1. Use a lock file (e.g., .beads/.daemon.lock) with PID
2. On daemon start, check if lock exists and process is alive
3. If stale lock (dead PID), clean up and acquire lock
4. If active daemon exists, either:
   - Exit with message 'daemon already running (PID xxx)'
   - Or offer --replace flag to kill existing and take over
5. Release lock on graceful shutdown

**Edge cases to handle:**
- Daemon crashes without releasing lock (stale PID detection)
- Multiple repos in same directory tree (each repo gets own lock)
- Race between two daemons starting simultaneously (atomic lock acquisition)


Implement alias conflict resolution

Handle alias conflicts when multiple clones assign same alias to different issues.

## Scenario
```
Clone A: Creates bd-a1b2c3d4, assigns alias #42
Clone B: Creates bd-e5f6a7b8, assigns alias #42
After sync: Conflict! Which issue gets #42?
```

## Resolution Strategy: Content-Hash Ordering
Deterministic, same result on all clones:
```go
func ResolveAliasConflicts(conflicts []AliasConflict) []AliasRemapping {
    for _, conflict := range conflicts {
        // Sort by hash ID (lexicographic)
        sort.Strings(conflict.IssueIDs)

        // Winner: lowest hash ID (arbitrary but deterministic)
        winner := conflict.IssueIDs[0]

        // Losers: reassign to next available aliases
        for _, loser := range conflict.IssueIDs[1:] {
            newAlias := getNextAlias()
            remappings = append(remappings, AliasRemapping{
                IssueID:  loser,
                OldAlias: conflict.Alias,
                NewAlias: newAlias,
            })
        }
    }
    return remappings
}
```

## Detection During Import
File: internal/importer/importer.go
```go
func handleAliasConflicts(imported []Issue, existing []Issue) error {
    // Build alias map from imported issues
    aliasMap := make(map[int][]string)  // alias → issue IDs

    for _, issue := range imported {
        aliasMap[issue.Alias] = append(aliasMap[issue.Alias], issue.ID)
    }

    // Check against existing aliases
    for alias, importedIDs := range aliasMap {
        existingID := storage.GetIssueIDByAlias(alias)
        if existingID != "" {
            // Conflict! Resolve it
            allIDs := append(importedIDs, existingID)
            conflicts = append(conflicts, AliasConflict{
                Alias:    alias,
                IssueIDs: allIDs,
            })
        }
    }

    // Resolve and apply
    remappings := ResolveAliasConflicts(conflicts)
    applyAliasRemappings(remappings)
}
```

## Alternative Strategies (For Future Consideration)

### Priority-Based
```go
// Higher priority keeps alias
if issueA.Priority < issueB.Priority {
    winner = issueA
}
```

### Timestamp-Based (Last-Write-Wins)
```go
// Newer issue keeps alias
if issueA.UpdatedAt.After(issueB.UpdatedAt) {
    winner = issueA
}
```

### Manual Resolution
```bash
bd resolve-aliases --manual
# Interactive prompt for each conflict
```

## User Notification
```bash
$ bd sync
✓ Synced 5 issues
⚠ Alias conflicts resolved:
  - Issue bd-e5f6a7b8: alias changed from #42 to #100
  - Issue bd-9a8b7c6d: alias changed from #15 to #101
```

## Files to Create/Modify
- internal/storage/sqlite/alias_conflicts.go (new)
- internal/importer/importer.go (detect conflicts)
- cmd/bd/sync.go (show conflict notifications)

## Testing
- Test two clones assign same alias to different issues
- Test conflict resolution is deterministic (same on all clones)
- Test loser gets new alias
- Test winner keeps original alias
- Test multiple conflicts resolved in one import


Consolidate export/import/commit/push into sync.go

Create internal/daemonrunner/sync.go with Syncer type. Add ExportOnce, ImportOnce, CommitAndMaybePush methods. Replace createExportFunc/createAutoImportFunc with thin closures calling Syncer.


Daemon crash recovery: panic handler + socket cleanup

Improve daemon cleanup on unexpected exit:
1. Add top-level recover() in runDaemonLoop to capture panics
2. Write daemon-error file with stack trace on panic
3. Prefer return over os.Exit where possible (so defers run)
4. In stopDaemon forced-kill path, also remove stale socket if present

This ensures better diagnostics and cleaner state after crashes.


Add schema compatibility probe to prevent silent migration failures

Issue #262 revealed a serious bug: migrations may fail silently, causing UNIQUE constraint errors later.

Root cause:
- sqlite.New() runs migrations once on open
- checkVersionMismatch() prints 'database will be upgraded automatically' but only updates metadata
- If migrations fail or daemon runs older version, queries expecting new columns fail with 'no such column'
- Import logic misinterprets this as 'not found' and tries INSERT on existing ID
- Result: UNIQUE constraint failed: issues.id

Fix strategy (minimal):
1. Add schema probe in sqlite.New() after RunMigrations
   - SELECT all expected columns from all tables with LIMIT 0
   - If fails, retry RunMigrations and probe again
   - If still fails, return fatal error with clear message
2. Fix checkVersionMismatch to not claim 'will upgrade' unless probe passes
3. Only update bd_version after successful migration probe
4. Add schema verification before import operations
5. Map 'no such column' errors to clear actionable message

**Highlight**: Deletion sync fix (bd-hv01)


Fix linting error in migrate.go

Linter reports error:
```
cmd/bd/migrate.go:647:37: cleanupWALFiles - result 0 (error) is always nil (unparam)
```

The `cleanupWALFiles` function always returns nil, so the error return type should be removed or the function should actually return errors when appropriate.


Implement content-hash based collision resolution for deterministic convergence

The current collision resolution uses creation timestamps to decide which issue to keep vs. remap. This is non-deterministic when two clones create issues at nearly the same time.

Root cause of bd-71107098:
- Clone A creates test-1="Issue from clone A" at T0
- Clone B creates test-1="Issue from clone B" at T0+30ms
- Clone B syncs first, remaps Clone A's to test-2
- Clone A syncs second, sees collision, remaps Clone B's to test-2
- Result: titles are swapped between clones

Solution:
- Use content-based hashing (title + description + priority + type)
- Deterministic winner: always keep issue with lower hash
- Same collision on different clones produces same result (idempotent)

Implementation:
- Modify ScoreCollisions in internal/storage/sqlite/collision.go
- Replace timestamp-based scoring with content hash comparison
- Ensure hash function is stable across platforms

Rename detection successfully implemented and tested!

**What was implemented:**
1. Content-hash based rename detection in DetectCollisions
2. When importing JSONL, if an issue has different ID but same content as DB issue, treat as rename
3. Delete old ID and accept new ID from JSONL
4. Added post-import re-export in sync command to flush rename changes
5. Added post-import commit to capture rename changes

**Test results:**
TestTwoCloneCollision now shows full convergence:
- Clone A: test-2="Issue from clone A", test-1="Issue from clone B"
- Clone B: test-1="Issue from clone B", test-2="Issue from clone A"

Both clones have **identical content** (titles match IDs correctly). Only timestamps differ (expected).

**What remains:**
- Test still expects exact JSON match including timestamps
- Could normalize timestamp comparison, but content convergence is the critical success metric
- The two-clone collision workflow now works without data corruption!


Add tombstone validation: require deleted_at for tombstone status

ValidateWithCustomStatuses() doesn't enforce that tombstones must have deleted_at set. Per bd-2m7 design: 'If status == tombstone, then deleted_at MUST be set'. Also should validate that non-tombstones cannot have deleted_at set.

Location: internal/types/types.go:109-114

Add validation:
- if i.Status == StatusTombstone && i.DeletedAt == nil: error
- if i.Status != StatusTombstone && i.DeletedAt != nil: error


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


Review PR #513: fix hooks install docs

Review and merge PR #513 from aspiers. This PR fixes incorrect docs for how to install git hooks - updates README to use bd hooks install instead of removed install.sh. Simple 1-line change. URL: https://github.com/anthropics/beads/pull/513


bd jira sync command

Add a built-in bd command for Jira synchronization.

**Requires**: Both import and export scripts working

**Features**:
- `bd jira sync --pull` - Import from Jira to beads
- `bd jira sync --push` - Export from beads to Jira
- `bd jira sync` - Bidirectional (pull then push, with conflict resolution)
- `bd jira status` - Show sync status and last sync time

**Conflict resolution**:
- Timestamp-based: newer update wins
- Option for --prefer-local or --prefer-jira to override
- Interactive mode for manual conflict resolution (optional)

**Integration**:
- Uses jira.* config settings from bd config
- Stores last sync timestamp in config
- Logs sync activity for audit

**Stretch goals**:
- Webhook integration for real-time sync
- Selective sync by JQL filter


Add ON DELETE CASCADE to child_counters schema

Update schema.go child_counters table foreign key with ON DELETE CASCADE. When parent deleted, child counter should also be deleted. If parent is resurrected, counter gets recreated from scratch. Add migration for existing databases.


Daemon fails to auto-import after git pull updates JSONL

After git pull updates .beads/issues.jsonl, daemon doesn't automatically re-import changes, causing stale data to be shown until next sync cycle (up to 5 minutes).

Reproduction:
1. Repo A: Close issues, export, commit, push
2. Repo B: git pull (successfully updates .beads/issues.jsonl)
3. bd show <issue> shows OLD status from daemon's SQLite db
4. JSONL on disk has correct new status

Root cause: Daemon sync cycle runs on timer (5min). When user manually runs git pull, daemon doesn't detect JSONL was updated externally and continues serving stale data from SQLite.

Impact:
- High for AI agents using beads in git workflows
- Breaks fundamental git-as-source-of-truth model
- Confusing UX: git log shows commit, bd shows old state
- Data consistency issues between JSONL and daemon

See WYVERN_SYNC_ISSUE.md for full analysis.

**Fixed in v0.21.2!**

The daemon auto-import is fully implemented:
- internal/autoimport package handles staleness detection
- internal/importer package provides shared import logic (used by both CLI and daemon)
- daemon's checkAndAutoImportIfStale() calls autoimport.AutoImportIfNewer()
- importFunc uses importer.ImportIssues() with auto-rename enabled
- All tests passing

The critical data corruption bug is FIXED:
✅ After git pull, daemon detects JSONL is newer (mtime check)
✅ Daemon auto-imports before serving requests
✅ No stale data served
✅ No data loss in multi-agent workflows

Verification needed: Run two-repo test to confirm end-to-end behavior.


Investigate and upgrade to modernc.org/sqlite 1.39.1+

We had to pin modernc.org/sqlite to v1.38.2 due to a FOREIGN KEY constraint regression in v1.39.1 (SQLite 3.50.4).

**Issue:** [deleted:bd-cb64c226.2], GH #144

**Symptom:** CloseIssue fails with "FOREIGN KEY constraint failed (787)" when called via MCP/daemon, but works fine via CLI.

**Root Cause:** Unknown - likely stricter FK enforcement in SQLite 3.50.4 or modernc.org wrapper changes.

**Workaround:** Pinned to v1.38.2 (SQLite 3.49.x)

**TODO:**
1. Monitor modernc.org/sqlite releases for fixes
2. Check SQLite 3.50.5+ changelogs for FK-related fixes
3. Investigate why daemon mode fails but CLI succeeds (connection reuse? transaction isolation?)
4. Consider filing upstream issue with reproducible test case
5. Upgrade when safe


bd prime: AI context loading and Claude Code integration

Implement `bd prime` command and Claude Code hooks for context recovery. Hooks work with BOTH MCP server and CLI approaches - they solve the context memory problem (keeping bd workflow fresh after compaction) not the tool access problem (MCP vs CLI).


Fix :memory: database connection pool issue causing "no such table" errors

Critical bug in v0.21.6 where :memory: databases with cache=shared create multiple connections in the pool, causing intermittent "no such table" errors. SQLite's shared cache for in-memory databases only works reliably with a single connection.

Root cause: Missing db.SetMaxOpenConns(1) after sql.Open() for :memory: databases.

Impact: 37 test failures in VC project, affects all consumers using :memory: for testing.


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


Design tombstone merge semantics

Define how tombstones participate in 3-way merge. Key question: does tombstone always win over live issue (like current deletion-wins rule), or should we use updated_at comparison? Consider: tombstone with older timestamp vs live issue with newer edits. Recommendation: tombstone wins unless expired, matching current behavior but with longer TTL window.


bd preflight: PR readiness checks for contributors

## Vision

Encode project-specific institutional knowledge into executable checks. CONTRIBUTING.md is documentation that's read once and forgotten; `bd preflight` is documentation that runs at exactly the right moment.

## Problem Statement

Contributors face a "last mile" problem - they do the work but stumble on project-specific gotchas at PR time:
- Nix vendorHash gets stale when go.sum changes
- Beads artifacts leak into PRs (see bd-umbf for namespace solution)
- Version mismatches between version.go and default.nix
- Tests/lint not run locally before pushing
- Other project-specific checks that only surface when CI fails

These are too obscure to remember, exist in docs nobody reads end-to-end, and waste CI round-trips.

## Why beads?

Beads already has a foothold in the contributor workflow. It knows:
- Git state (staged files, branch, dirty status)
- Project structure
- The specific issue being worked on
- Project-specific configuration

## Proposed Interface

### Tier 1: Checklist Mode (v1)

    $ bd preflight
    PR Readiness Checklist:

    [ ] Tests pass: go test -short ./...
    [ ] Lint passes: golangci-lint run ./...
    [ ] No beads pollution: check .beads/issues.jsonl diff
    [ ] Nix hash current: go.sum unchanged or vendorHash updated
    [ ] Version sync: version.go matches default.nix

    Run 'bd preflight --check' to validate automatically.

### Tier 2: Check Mode (v2)

    $ bd preflight --check
    ✓ Tests pass
    ✓ Lint passes
    ⚠ Beads pollution: 3 issues in diff - are these project issues or personal?
    ✗ Nix hash stale: go.sum changed, vendorHash needs update
      Fix: sha256-KRR6dXzsSw8OmEHGBEVDBOoIgfoZ2p0541T9ayjGHlI=
    ✓ Version sync

    1 error, 1 warning. Run 'bd preflight --fix' to auto-fix where possible.

### Tier 3: Fix Mode (v3)

    $ bd preflight --fix
    ✓ Updated vendorHash in default.nix
    ⚠ Cannot auto-fix beads pollution - manual review needed

## Checks to Implement

| Check | Description | Auto-fixable |
|-------|-------------|--------------|
| tests | Run go test -short ./... | No |
| lint | Run golangci-lint | Partial (gofmt) |
| beads-pollution | Detect personal issues in diff | No (see bd-umbf) |
| nix-hash | Detect stale vendorHash | Yes (if nix available) |
| version-sync | version.go matches default.nix | Yes |
| no-debug | No TODO/FIXME/console.log | Warn only |
| clean-stage | No unintended files staged | Warn only |

## Future: Configuration

Make checks configurable per-project via .beads/preflight.yaml:

    preflight:
      checks:
        - name: tests
          run: go test -short ./...
          required: true
        - name: no-secrets
          pattern: "**/*.env"
          staged: deny
        - name: custom-check
          run: ./scripts/validate.sh

This lets any project using beads define their own preflight checks.

## Implementation Phases

### Phase 1: Static Checklist
- Implement bd preflight with hardcoded checklist for beads
- No execution, just prints what to check
- Update CONTRIBUTING.md to reference it

### Phase 2: Automated Checks
- Implement bd preflight --check
- Run tests, lint, detect stale hashes
- Clear pass/fail/warn output

### Phase 3: Auto-fix
- Implement bd preflight --fix
- Fix vendorHash, version sync
- Integrate with bd-umbf solution for pollution

### Phase 4: Configuration
- .beads/preflight.yaml support
- Make it useful for other projects using beads
- Plugin/hook system for custom checks

## Dependencies

- bd-umbf: Namespace isolation for beads pollution (blocking for full solution)

## Success Metrics

- Fewer CI failures on first PR push
- Reduced "fix nix hash" commits
- Contributors report preflight caught issues before CI
