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.


Fix daemon exiting after 5s on macOS due to PID 1 parent monitoring

GitHub issue #278 reports that the daemon exits after <=5 seconds on macOS because it incorrectly treats PID 1 (launchd) as a dead parent.

When the daemon detaches on macOS, it gets reparented to PID 1 (launchd), which is the init process. The checkParentProcessAlive function was incorrectly treating PID 1 as a sign that the parent died.

Fixed by changing the logic to treat PID 1 as a valid parent for detached daemons.


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


Refactor: Move staleness check inside daemon branch

## Problem

Currently ensureDatabaseFresh() is called before the daemon mode check, but it checks daemonClient != nil internally and returns early. This is redundant.

**Location:** All read commands (list.go:196, show.go:27, ready.go:102, status.go:80, etc.)

## Current Pattern

Call happens before daemon check, function checks daemonClient internally.

## Better Pattern

Move staleness check to direct mode branch only, after daemon check.

## Impact
Low - minor performance improvement (avoids one function call per command in daemon mode)

## Effort
Medium - requires refactoring 8 command files

## Priority
Low - can defer to future cleanup PR


UX nightmare: multiple ways daemon can fail with misleading messages


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


bd doctor: add SQLite integrity check (PRAGMA integrity_check)

Add a database integrity check using SQLite's PRAGMA integrity_check to detect corruption. Currently bd doctor checks schema compatibility but not data integrity. This would help diagnose corrupted databases that pass schema checks but have internal inconsistencies.


Create Go adapter library (optional)

For agents written in Go, provide native adapter library instead of shelling out to curl.

Acceptance Criteria:
- agentmail.Client struct
- HTTP client with timeout/retry logic
- Same API as Python adapter
- Example usage in examples/go-agent/
- Unit tests

File: pkg/agentmail/client.go

Note: Lower priority - can shell out to curl initially


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 transaction retry logic for SQLITE_BUSY

BEGIN IMMEDIATE fails immediately on SQLITE_BUSY instead of retrying with exponential backoff.

Location: internal/storage/sqlite/sqlite.go:223-225

Problem:
- Under concurrent write load, BEGIN IMMEDIATE can fail with SQLITE_BUSY
- Current implementation fails immediately instead of retrying
- Results in spurious failures under normal concurrent usage

Solution: Implement exponential backoff retry:
- Retry up to N times (e.g., 5)
- Backoff: 10ms, 20ms, 40ms, 80ms, 160ms
- Check for context cancellation between retries
- Only retry on SQLITE_BUSY/database locked errors

Impact: Spurious failures under concurrent write load

Effort: 3 hours

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

Add external_ref change tracking and auditing

Currently we don't track when external_ref is added, removed, or changed. This would be useful for debugging and auditing.

Proposed features:
- Log event when external_ref changes
- Track in events table with old/new values
- Add query to find issues where external_ref changed
- Add metrics: issues with external_ref vs without

Use cases:
- Debugging import issues
- Understanding which issues are externally managed
- Auditing external system linkage

bd info shows 'auto_start_disabled' even when daemon is crashed/missing


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.


bd message: Implement full message reading functionality

The `bd message read` command is incomplete and doesn't actually fetch or display message content.

**Location:** cmd/bd/message.go:413-441

**Current Behavior:**
- Only marks message as read
- Prints placeholder text
- Doesn't fetch message body

**Expected:**
- Fetch full message from Agent Mail resource API
- Display sender, subject, timestamp, body
- Consider markdown rendering

**Blocker:** Core feature for message system MVP


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)

purgeDeletedIssues still writes to deletions.jsonl during git-history-backfill

In purgeDeletedIssues (lines 929-939), when a deletion is recovered from git history, we:
1. Append to deletions.jsonl (backfill)
2. Create a tombstone in DB

With the tombstone approach, writing to deletions.jsonl is redundant since the tombstone will be exported to JSONL. Consider removing the deletions.jsonl backfill once we're confident in the tombstone approach.

This is related to the Phase 2 migration (bd-vw8) - we should stop writing to deletions.jsonl entirely.


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

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,
}
```

AI-supervised database migrations for safer schema evolution

## Problem

Database migrations can lose user data through edge cases that are hard to anticipate (e.g., GH #201 where bd migrate failed to set issue_prefix, or bd-d355a07d false positive data loss warnings). Since beads is designed to be run by AI agents, we should leverage AI to make migrations safer.

## Current State

Migrations run blindly with:
- No pre-flight validation
- No data integrity verification
- No rollback on failure
- Limited post-migration testing

Recent issues:
- GH #201: Migration didn't set issue_prefix config, breaking commands
- bd-d355a07d: False positive "data loss" warnings on collision resolution
- Users reported migration data loss (fixed but broader problem remains)

## Proposal: AI-Supervised Migration Framework

Use AI to supervise migrations through structured verification:

### 1. Pre-Migration Analysis
- AI reads migration code and current schema
- Identifies potential data loss scenarios
- Generates validation queries to verify assumptions
- Creates snapshot queries for before/after comparison

### 2. Migration Execution
- Take database backup/snapshot
- Run validation queries (pre-state)
- Execute migration in transaction
- Run validation queries (post-state)

### 3. Post-Migration Verification
- AI compares pre/post snapshots
- Verifies data integrity invariants
- Checks for unexpected data loss
- Validates config completeness (like issue_prefix)

### 4. Rollback on Anomalies
- If AI detects data loss, rollback transaction
- Present human-readable error report
- Suggest fix before retrying

## Example Flow

```
$ bd migrate

→ Analyzing migration plan...
→ AI identified 3 potential data loss scenarios
→ Generating validation queries...
→ Creating pre-migration snapshot...
→ Running migration in transaction...
→ Verifying post-migration state...
✓ All 247 issues accounted for
✓ Config table complete (issue_prefix: "mcp")
✓ Dependencies intact (342 relationships verified)
→ Migration successful!
```

If something goes wrong:
```
$ bd migrate

→ Analyzing migration plan...
→ AI identified issue: Missing issue_prefix config after migration
→ Recommendation: Add prefix detection step
→ Aborting migration - database unchanged
```

## Implementation Ideas

### A. Migration Validator Tool
Create `bd migrate --validate` that:
- Simulates migration on copy of database
- Uses AI to verify data integrity
- Reports potential issues before real migration

### B. Migration Test Generator
AI generates test cases for migrations:
- Edge cases (empty DB, large DB, missing config)
- Data integrity checks
- Regression tests

### C. Migration Invariants
Define invariants that AI checks:
- Issue count should not decrease (unless collision resolution)
- All required config keys present
- Foreign key relationships intact
- No orphaned dependencies

### D. Self-Healing Migrations
AI detects incomplete migrations and suggests fixes:
- Missing config values (like GH #201)
- Orphaned data
- Index inconsistencies

## Benefits

1. **Catch edge cases**: AI explores scenarios humans miss
2. **Self-documenting**: AI explains what migration does
3. **Agent-friendly**: Agents can run migrations confidently
4. **Fewer rollbacks**: Detect issues before committing
5. **Better testing**: AI generates comprehensive test suites

## Open Questions

1. Which AI model? (Fast: Haiku, Thorough: Sonnet/GPT-4)
2. How to balance safety vs migration speed?
3. Should AI validation be required or optional?
4. How to handle offline scenarios (no API access)?
5. What invariants should always be checked?

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


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.


bd import fails on duplicate external_ref with no resolution options

When JSONL contains duplicate external_ref values (e.g., two issues both have external_ref='BS-170'), bd import fails entirely with no resolution options.

User must manually edit JSONL to remove duplicates, which is error-prone.

Example error:
```
batch import contains duplicate external_ref values:
external_ref 'BS-170' appears in issues: [opal-39 opal-43]
```

Should handle this similar to duplicate issue detection - offer to merge, pick one, or clear duplicates.


bd init --contributor should configure sync.remote=upstream for fork workflows

When running `bd init --contributor` in a fork workflow (where `upstream` remote points to the original repo), the wizard should configure beads to sync from `upstream/main` rather than `origin/main`.

**Current behavior:**
- Contributor mode detects the fork setup (upstream remote exists)
- Sets up planning repo and auto-routing
- Does NOT configure sync remote
- `bd sync` on feature branches shows "No upstream configured, using --from-main mode" and syncs from `origin/main`

**Expected behavior:**
- Contributor mode should also set `sync.remote = upstream` (or similar config)
- `bd sync` should pull beads from `upstream/main` (source of truth)

**Why this matters:**
- The fork's `origin/main` may be behind `upstream/main`
- Contributors want the latest issues from the source repo
- Code PRs go: local -> origin -> upstream, but beads should come FROM upstream

**Suggested fix:**
Add to `runContributorWizard()` after detecting fork:
```go
if isFork {
    store.SetConfig(ctx, "sync.remote", "upstream")
}
```


Testing event-driven mode!


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

bd-hv01: Three full JSONL reads on every sync (performance)

Problem: computeAcceptedDeletions reads three JSONL files completely into memory (base, left, merged). For 1000 issues at 1KB each, this is 3MB read and 3000 JSON parse operations.

Impact: Acceptable now (~20-35ms overhead) but will be slow for large repos (10k+ issues).

Possible optimizations: single-pass streaming, memory-mapped files, binary format, incremental snapshots.

Files: cmd/bd/deletion_tracking.go:101-208


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.

User Diagnostics (bd doctor --perf)

Extend cmd/bd/doctor.go to add --perf flag for user performance diagnostics.

Functionality:
- Add --perf flag to existing bd doctor command
- Collect system info (OS, arch, Go version, SQLite version)
- Collect database stats (size, issue counts, dependency counts)
- Time key operations on user's actual database:
  * bd ready
  * bd list --status=open
  * bd show <random-issue>
  * bd create (with rollback)
  * Search with filters
- Generate CPU profile automatically (timestamped filename)
- Output simple report with platform info, timings, profile location

Output example:
  Beads Performance Diagnostics
  Platform: darwin/arm64
  Database: 8,234 issues (4,123 open)

  Operation Performance:
    bd ready                  42ms
    bd list --status=open     15ms

  Profile saved: beads-perf-2025-11-13.prof
  View: go tool pprof -http=:8080 beads-perf-2025-11-13.prof

Implementation:
- Extend cmd/bd/doctor.go (~100 lines)
- Use runtime/pprof for CPU profiling
- Use time.Now()/time.Since() for timing
- Rollback test operations (don't modify user's database)


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


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

Refactor: deduplicate FindJSONLInDir and FindJSONLPath

## Background

After fixing bd-tqo, we now have two nearly identical functions for finding the JSONL file:
- `autoimport.FindJSONLInDir(dbDir string)` in internal/autoimport/autoimport.go
- `beads.FindJSONLPath(dbPath string)` in internal/beads/beads.go

Both implement the same logic:
1. Prefer issues.jsonl
2. Fall back to beads.jsonl for legacy support
3. Skip deletions.jsonl and merge artifacts
4. Default to issues.jsonl if nothing found

## Problem

Code duplication means bug fixes need to be applied in multiple places (as we just experienced with bd-tqo).

## Proposed Solution

Extract shared logic to a utility package that both can import. Options:
1. Create `internal/jsonlpath` package with the core logic
2. Have `autoimport` import `beads` and call `FindJSONLPath` (but APIs differ slightly)
3. Move to `internal/utils` if appropriate

Need to verify no import cycles would be created.

## Affected Files
- internal/autoimport/autoimport.go
- internal/beads/beads.go


Auto-push after merge with safety check

Make bd sync a true one-command solution by auto-pushing after successful content merge.

Behavior:
- After successful content merge, auto-push by default
- Safety check: detect when >50% issues vanished AND >5 existed before
- On safety check trigger: warn but still push (do not block happy path)

Vanished means issues removed from issues.jsonl entirely, NOT status=closed (closed is legitimate swarm completion).

Location: internal/syncbranch/worktree.go
Parent issue: bd-3s8

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


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'.


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


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

Fix autoimport tests for content-hash collision scoring

## Overview
Three autoimport tests are failing after [deleted:bd-cbed9619.4] because they expect behavior based on the old reference-counting collision resolution, but the system now uses deterministic content-hash scoring.

## Failing Tests
1. `TestAutoImportMultipleCollisionsRemapped` - expects local versions preserved
2. `TestAutoImportAllCollisionsRemapped` - expects local versions preserved
3. `TestAutoImportCollisionRemapMultipleFields` - expects specific collision resolution behavior

## Root Cause
These tests were written when ScoreCollisions used reference counting to determine which version to keep. Now it uses content-hash comparison (introduced in commit 2e87329), which produces different but deterministic results.

## Example
Old behavior: Issue with more references would be kept
New behavior: Issue with lexicographically lower content hash is kept

## Solution
Update each test to:
1. Verify the new content-hash based behavior is correct
2. Check that the remapped issue (not necessarily local/remote) has the expected content
3. Ensure dependencies are preserved on the correct remapped issue

## Acceptance Criteria
- All three autoimport tests pass
- Tests verify content-hash determinism (same collision always resolves the same way)
- Tests check dependency preservation on remapped issues
- Test documentation explains content-hash scoring expectations

## Files to Modify
- `cmd/bd/autoimport_collision_test.go`

## Testing
Run: `go test ./cmd/bd -run "TestAutoImport.*Collision" -v`


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)


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.


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

Latency test 1


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.


Backend task


Doctor should exclude merge artifacts from 'multiple JSONL' warning

Doctor command warns about 'multiple JSONL files' when .base.jsonl and .left.jsonl merge artifacts exist. These are expected during/after merge operations and should be excluded from the warning.


Update git hooks to be sync.branch aware

## Problem

The pre-push hook blocks pushes when .beads/issues.jsonl has uncommitted changes. But with sync.branch configured, those changes are intentionally NOT committed to main - they go to the sync branch via worktree.

## Current Behavior

1. User configures sync.branch=beads-sync
2. bd sync commits changes to beads-sync via worktree
3. Local .beads/issues.jsonl is updated (needed for import)
4. git push to main triggers pre-push hook
5. Hook sees uncommitted .beads changes and blocks push
6. User must use --no-verify to push

## Expected Behavior

When sync.branch is configured, the pre-push hook should:
1. Check if sync.branch is set (bd config get sync.branch)
2. If set, skip the .beads uncommitted check OR
3. Verify changes are committed to the sync branch instead

## Affected Files

- examples/git-hooks/pre-push
- examples/git-hooks/pre-commit (may also need update)

## Workaround

Use git push --no-verify


bd sync should not stage gitignored snapshot files

## Problem

`gitCommitBeadsDir` in `cmd/bd/sync.go` runs `git add .beads/` which stages all files in the directory, including snapshot files that are listed in `.beads/.gitignore`.

If a snapshot file (e.g., `beads.left.meta.json`) was ever committed before being added to `.gitignore`, git continues to track it. This causes merge conflicts when multiple polecats run `bd sync` concurrently, since each one modifies and commits these temporary files.

## Root Cause

Line ~568 in sync.go:
```go
addCmd := exec.CommandContext(ctx, "git", "add", beadsDir)
```

This stages everything in `.beads/`, but `.gitignore` only prevents *untracked* files from being added - it doesn't affect already-tracked files.

## Suggested Fix

Option A: After `git add .beads/`, run `git reset` on snapshot files:
```go
exec.Command("git", "reset", "HEAD", ".beads/beads.*.jsonl", ".beads/*.meta.json")
```

Option B: Stage only specific files instead of the whole directory:
```go
exec.Command("git", "add", ".beads/issues.jsonl", ".beads/deletions.jsonl", ".beads/metadata.json")
```

Option C: Detect and untrack snapshot files if they're tracked:
```go
// Check if file is tracked: git ls-files --error-unmatch <file>
// If tracked, run: git rm --cached <file>
```

Option B is probably cleanest - explicitly add only the files that should be committed.

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._


Add bd migrate-tombstones command

Create migration command to convert existing deletions.jsonl entries to tombstones. Support --dry-run and --verbose flags. Archive old file with .migrated suffix. Per design bd-dli.


Duplicate tombstone constants in merge and types packages

## Problem

The tombstone constants are duplicated between two packages:

**internal/types/types.go:**
```go
const DefaultTombstoneTTL = 30 * 24 * time.Hour
const ClockSkewGrace = 1 * time.Hour
const StatusTombstone Status = "tombstone"
```

**internal/merge/merge.go:**
```go
const StatusTombstone = "tombstone"
const DefaultTombstoneTTL = 30 * 24 * time.Hour
const ClockSkewGrace = 1 * time.Hour
```

This violates DRY and creates risk of divergence if one is updated but not the other.

## Root Cause

The merge package has its own `Issue` struct (for JSONL parsing) and cannot import types.Issue directly due to the different struct design. However, the constants could be shared.

## Recommendation

Export the constants from types package and import them in merge:

```go
// merge/merge.go
import "github.com/steveyegge/beads/internal/types"

// Use types.StatusTombstone, types.DefaultTombstoneTTL, types.ClockSkewGrace
```

Or create a shared constants package if import cycles are a concern.

Design hash ID generation algorithm

Design and specify the hash-based ID generation algorithm.

## Requirements
- Deterministic: same inputs → same ID
- Collision-resistant: ~2^32 space for 8-char hex
- Fast: <1μs per generation
- Includes timestamp for uniqueness
- Includes creator/workspace for distributed uniqueness

## Proposed Algorithm
```go
func GenerateIssueID(title, desc string, created time.Time, workspaceID string) string {
    h := sha256.New()
    h.Write([]byte(title))
    h.Write([]byte(desc))
    h.Write([]byte(created.Format(time.RFC3339Nano)))
    h.Write([]byte(workspaceID))
    hash := hex.EncodeToString(h.Sum(nil))
    return "bd-" + hash[:8]  // 8-char prefix = 2^32 space
}
```

## Open Questions
1. 8 chars (2^32) or 16 chars (2^64) for collision resistance?
2. Include priority/type in hash? (Pro: more entropy. Con: immutable)
3. How to handle workspace ID generation? (hostname? UUID?)
4. What if title+desc change? (Answer: ID stays same - hash only used at creation)

## Deliverables
- Design doc: docs/HASH_ID_DESIGN.md
- Collision probability analysis
- Performance benchmarks
- Prototype implementation in internal/types/id_generator.go

bd init UX Improvements

bd init leaves users with incomplete setup, requiring manual bd doctor --fix. Issues found: (1) git hooks not installed if user declines prompt, (2) no auto-migration when CLI is upgraded, (3) stale merge driver configs from old versions. Fix by making bd init more robust with better defaults and auto-migration.


Add orphan detection migration

Create migration to detect orphaned children in existing databases. Query: SELECT id FROM issues WHERE id LIKE '%.%' AND substr(id, 1, instr(id || '.', '.') - 1) NOT IN (SELECT id FROM issues). Log results, let user decide action (delete orphans or convert to top-level).


## Overview
Three autoimport tests are failing after bd-cbed9619.4 because they expect behavior based on the old reference-counting collision resolution, but the system now uses deterministic content-hash scoring.

## Failing Tests
1. `TestAutoImportMultipleCollisionsRemapped` - expects local versions preserved
2. `TestAutoImportAllCollisionsRemapped` - expects local versions preserved
3. `TestAutoImportCollisionRemapMultipleFields` - expects specific collision resolution behavior

## Root Cause
These tests were written when ScoreCollisions used reference counting to determine which version to keep. Now it uses content-hash comparison (introduced in commit 2e87329), which produces different but deterministic results.

## Example
Old behavior: Issue with more references would be kept
New behavior: Issue with lexicographically lower content hash is kept

## Solution
Update each test to:
1. Verify the new content-hash based behavior is correct
2. Check that the remapped issue (not necessarily local/remote) has the expected content
3. Ensure dependencies are preserved on the correct remapped issue

## Acceptance Criteria
- All three autoimport tests pass
- Tests verify content-hash determinism (same collision always resolves the same way)
- Tests check dependency preservation on remapped issues
- Test documentation explains content-hash scoring expectations

## Files to Modify
- `cmd/bd/autoimport_collision_test.go`

## Testing
Run: `go test ./cmd/bd -run "TestAutoImport.*Collision" -v`

Add tests for daemon config module


Improve compact/daemon/merge documentation and UX

Multiple documentation and UX issues encountered:
1. "bd compact --analyze" fails with misleading "requires SQLite storage" error when daemon is running. Needs --no-daemon or better error.
2. "bd merge" help text is outdated (refers to 3-way merge instead of issue merging).
3. Daemon mode purpose isn't clear to local-only users.
4. Compact/cleanup commands are hard to discover.

Proposed fixes:
- Fix compact+daemon interaction or error message.
- Update "bd merge" help text.
- Add "when to use daemon" section to docs.
- Add maintenance section to quickstart.


Auto-invoke 3-way merge for JSONL conflicts

Currently when git pull encounters merge conflicts in .beads/issues.jsonl, the post-merge hook fails with an error message pointing users to manual resolution or the beads-merge tool.

This is a poor user experience - the conflict detection is working, but we should automatically invoke the advanced 3-way merging instead of just telling users about it.

**Current behavior:**
- Detect conflict markers in JSONL
- Display error with manual resolution options
- Exit with failure

**Desired behavior:**
- Detect conflict markers in JSONL
- Automatically invoke beads-merge 3-way merge
- Only fail if automatic merge cannot resolve the conflicts

**Reference:**

Add content-addressable identity to Issue type

## Overview
Phase 1: Add content hashing to enable global identification of issues regardless of their assigned IDs.

## Current Problem
The system identifies issues only by ID (e.g., test-1, test-2). When multiple clones create the same ID with different content, there's no way to identify that these are semantically different issues without comparing all fields.

## Solution
Add a ContentHash field to the Issue type that represents the canonical content fingerprint.

## Implementation Tasks

### 1. Add ContentHash field to Issue type
File: internal/types/types.go
```go
type Issue struct {
    ID          string
    ContentHash string  // SHA256 of canonical content
    // ... existing fields
}
```

### 2. Add content hash computation method
Use existing hashIssueContent from collision.go:186 as foundation:
```go
func (i *Issue) ComputeContentHash() string {
    return hashIssueContent(i)
}
```

### 3. Compute hash at creation time
- Modify CreateIssue to compute and store ContentHash
- Modify CreateIssues (batch) to compute hashes

### 4. Compute hash at import time
- Modify ImportIssues to compute ContentHash for all incoming issues
- Store hash in database

### 5. Add database column
- Add migration to add content_hash column to issues table
- Update SELECT/INSERT statements to include content_hash
- Index on content_hash for fast lookups

### 6. Populate existing issues
- Add migration step to compute ContentHash for all existing issues
- Use hashIssueContent function

## Acceptance Criteria
- Issue type has ContentHash field
- Hash is computed automatically at creation time
- Hash is computed for imported issues
- Database stores content_hash column
- All existing issues have non-empty ContentHash
- Hash is deterministic (same content → same hash)
- Hash excludes ID, timestamps (only semantic content)

## Files to Modify
- internal/types/types.go
- internal/storage/sqlite/sqlite.go (schema, CreateIssue, CreateIssues)
- internal/storage/sqlite/migrations.go (new migration)
- internal/importer/importer.go (compute hash during import)
- cmd/bd/create.go (compute hash at creation)

## Testing
- Unit test: same content produces same hash
- Unit test: different content produces different hash
- Unit test: hash excludes ID and timestamps
- Integration test: hash persists in database
- Migration test: existing issues get hashes populated


bd doctor: detect and fix stale beads-sync branch

## Problem

When beads-sync diverges significantly from main (on source code, not just .beads/), it needs to be reset. After a force-push reset, other clones/contributors will have orphaned local beads-sync branches.

## Symptoms
- Local beads-sync is many commits behind main on source files
- Local beads-sync doesn't share recent history with remote beads-sync (after force-push)
- bd sync may behave unexpectedly

## Proposed bd doctor checks

1. **Check beads-sync alignment with main**
   - If beads-sync exists and is >N commits behind main on non-.beads/ files, warn
   - Suggests: reset beads-sync to main

2. **Check beads-sync alignment with remote**
   - If local beads-sync has diverged from origin/beads-sync (no common recent ancestor)
   - This happens after someone force-pushed a reset
   - Suggests: reset local beads-sync to origin/beads-sync

## Proposed fixes (--fix)

- Reset local beads-sync branch to origin/beads-sync or main
- Handle worktree if present (git worktree remove, then recreate on next sync)

## Context
Discovered when beads-sync drifted 126 commits behind main. Required manual reset and force-push. Contributors will need to reset their local branches too.


Add is_tombstone flag to schema

Optionally add is_tombstone boolean field to issues table. Marks resurrected parents that were deleted. Allows distinguishing tombstones from normal deleted issues. Update schema.go and create migration.


Add label-based filtering to bd ready command

Allow filtering ready work by labels to help organize work by sprint, week, or category.

Example usage:
  bd ready --label week1-2
  bd ready --label frontend,high-priority

This helps teams organize work into batches and makes it easier for agents to focus on specific categories of work.

Implementation notes:
- Add --label flag to ready command
- Support comma-separated labels (AND logic)
- Should work with existing ready work logic (unblocked issues)


Migration tool for existing users

Ensure smooth migration for existing users to separate branch workflow.

Tasks:
- Add bd migrate --separate-branch command
- Detect existing repos, migrate cleanly
- Preserve git history
- Add rollback mechanism
- Test migration on beads' own repo (dogfooding)
- Communication plan (GitHub discussion, docs)
- Version compatibility checks

Estimated effort: 2-3 days

Rapid 4


Enforce daemon singleton per workspace with file locking

Agent in ~/src/wyvern discovered 4 simultaneous daemon processes running, causing infinite directory recursion (.beads/.beads/.beads/...). Each daemon used relative paths and created nested .beads/ directories.

Root cause: No singleton enforcement. Multiple `bd daemon` processes can start in same workspace.

Expected: One daemon per workspace (each workspace = separate .beads/ dir with bd.sock)
Actual: Multiple daemons can run simultaneously in same workspace

Note: Separate git clones = separate workspaces = separate daemons (correct). Git worktrees share .beads/ and have known limitations (documented, use --no-daemon).

## Fix Summary

Successfully prevented the nested .beads/.beads/ recursion bug by implementing two safeguards:

1. **Path Canonicalization in FindDatabasePath()** (beads.go):
   - Added filepath.Abs() + filepath.EvalSymlinks() to normalize all database paths
   - Prevents relative path edge cases that create nested directories
   - Ensures all daemons see the same canonical path

2. **Nested Directory Detection** (daemon_lifecycle.go):
   - Added explicit check for ".beads/.beads" pattern in setupDaemonLock()
   - Fails fast with clear error message if nested structure detected
   - Provides user hints about proper usage

## Root Cause

The daemon lock (added Oct 22, 2025) correctly prevents simultaneous daemons in the SAME workspace. However, when BEADS_DB used a relative path (e.g., ".beads/beads.db") from inside the .beads directory, FindDatabasePath() would resolve it to a nested path creating a separate workspace:
- First daemon: /workspace/.beads/beads.db
- Second daemon from .beads/: /workspace/.beads/.beads/beads.db ← Different lock file!

## Testing

All acceptance criteria passed:
✅ 1. Second daemon start fails with "daemon already running" error
✅ 2. Killing daemon releases lock, new daemon can start
✅ 3. No infinite .beads/ recursion possible (tested nested BEADS_DB path)
✅ 4. Works with auto-start mechanism

The fix addresses the edge case while maintaining the existing lock mechanism's correctness.


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


Optimize CLI test suite - eliminate redundant git init calls

Current: Each of 13 CLI tests calls git init (31s total). Solution: Use single test binary built once in init(), skip git operations where possible, or use mock filesystem.


Expand checkHooksQuick to verify all hook versions

Currently checkHooksQuick only checks post-merge hook version. Should also check pre-commit, pre-push, and post-checkout for completeness. Keep it lightweight but catch more outdated hooks.


Add programmatic tip injection API

Allow tips to be programmatically injected at runtime based on detected conditions. This enables dynamic tips (not just pre-defined ones) to be shown with custom priority and frequency.


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


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)

**Files**:
- `internal/merge/merge_test.go`
- `cmd/bd/merge_test.go`


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.


Git history fallback has incorrect logic for detecting deletions

## Problem

The `wasInGitHistory` function in `internal/importer/importer.go:891` returns true if the ID is found **anywhere** in git history. But finding an ID in history doesn't necessarily mean it was deleted - it could mean:

1. The issue was added (appears in a commit adding it)
2. The issue was modified (appears in commits updating it)
3. The issue was deleted (appears in a commit removing it)

The current logic incorrectly treats all three cases as 'deleted'.

## Correct Logic

`git log -S` with `--oneline` shows commits where the string was added OR removed. To detect deletion specifically:

1. ID appears in git history (was once in JSONL)
2. ID is NOT currently in JSONL

The second condition is already checked by the caller (`purgeDeletedIssues`), so technically the logic is correct in context. But the function name and doc comment are misleading.

## Fix Options

1. **Rename function** to `wasEverInJSONL` and update doc comment to clarify
2. **Add explicit check** for current JSONL state in the function itself

Option 1 is simpler and correct since caller already filters.


Delete collision resolution code

Remove ~2,100 LOC of ID collision detection and resolution code (no longer needed with hash IDs).

## Files to Delete Entirely
```
internal/storage/sqlite/collision.go              (~800 LOC)
internal/storage/sqlite/collision_test.go         (~300 LOC)
cmd/bd/autoimport_collision_test.go               (~400 LOC)
```

## Code to Remove from Existing Files

### internal/importer/importer.go
Remove:
- `DetectCollisions()` calls
- `ScoreCollisions()` logic
- `RemapCollisions()` calls
- `handleRename()` function
- All collision-related error handling

Keep:
- Basic import logic
- Exact match detection (idempotent import)

### beads_twoclone_test.go
Remove:
- `TestTwoCloneCollision` (bd-71107098)
- `TestThreeCloneCollision` (bd-cbed9619)
- `TestFiveCloneCollision` (bd-a40f374f)
- All N-way collision tests

### cmd/bd/import.go
Remove:
- `--resolve-collisions` flag
- `--dry-run` collision preview
- Collision reporting

## Issues Closed by This Change
- bd-71107098: Add test for symmetric collision
--89: Content-hash collision resolution
- bd-cbed9619: N-way collision resolution epic
- bd-cbed9619.5: Add ScoreCollisions (already done but now unnecessary)
- bd-cbed9619.4: Make DetectCollisions read-only
- bd-cbed9619.3: ResolveNWayCollisions function
- bd-cbed9619.2: Multi-round import convergence
- bd-cbed9619.1: Multi-round convergence for N-way collisions
- bd-e6d71828: Transaction + retry logic for collisions
- bd-70419816: Test case for symmetric collision

## Verification Steps
1. `grep -r "collision" --include="*.go"` → should only find alias conflicts
2. `go test ./...` → all tests pass
3. `go build ./cmd/bd` → clean build
4. Check LOC reduction: `git diff --stat`

## Expected Metrics
- **Files deleted**: 3
- **LOC removed**: ~2,100
- **Test coverage**: Should increase (less untested code)
- **Binary size**: Slightly smaller

## Caution
Do NOT delete:
- Alias conflict resolution (new code in bd-f8b764c9.6)
- Duplicate detection (bd-581b80b3, bd-149) - different from ID collisions
- Merge conflict resolution (bd-7e7ddffa.1, bd-5f483051) - git conflicts, not ID collisions

## Files to Modify
- internal/importer/importer.go (remove collision handling)
- cmd/bd/import.go (remove --resolve-collisions flag)
- beads_twoclone_test.go (remove collision tests)
- Delete: internal/storage/sqlite/collision.go
- Delete: internal/storage/sqlite/collision_test.go
- Delete: cmd/bd/autoimport_collision_test.go

## Testing
- Ensure all remaining tests pass
- Manual test: create issue on two clones, sync → no collisions
- Verify error if somehow hash collision occurs (extremely unlikely)


Safety check tests use string(rune()) which only works for single digits


Clarify JSONL size bounds with multi-repo

The contributor-workflow-analysis.md states (line 226): 'Keep beads.jsonl small enough for agents to read (<25k)'

With multi-repo hydration, it's unclear whether this bound applies to:
- Each individual JSONL file (likely intention)
- The total hydrated size across all repos (unclear)
- Both (most conservative)

Clarification needed because:
- VC monitors .beads/issues.jsonl size to stay under limit
- With multi-repo, VC needs to know if each additional repo also has 25k limit
- Agents reading hydrated data need to know total size bounds
- Performance characteristics depend on total vs per-repo limits

Example scenario:
- Primary repo: 20k JSONL
- Planning repo: 15k JSONL
- Total hydrated: 35k
Is this acceptable or does it violate the <25k principle?


Default to YES for git hooks and merge driver installation

Currently bd init prompts user to install git hooks and merge driver, but setup is incomplete if user declines. Change to install by default unless --skip-hooks or --skip-merge-driver flags are passed. Better safe defaults. If installation fails, warn user and suggest bd doctor --fix.


Feature with design

Implement git worktree management

Create git worktree lifecycle management for separate beads branch.

Tasks:
- Create internal/git/worktree.go
- Implement CreateBeadsWorktree(branch, path)
- Implement RemoveBeadsWorktree(path)
- Implement CheckWorktreeHealth(path)
- Configure sparse checkout (only .beads/)
- Implement SyncJSONLToWorktree()
- Handle worktree errors gracefully
- Auto-cleanup on config change

Estimated effort: 3-4 days


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.


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)

Update docs with multi-repo patterns

Update AGENTS.md, README.md, QUICKSTART.md with multi-repo patterns. Document: config options, routing behavior, backward compatibility, troubleshooting, best practices.


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)


Invert control for compact: provide tools for agent-driven compaction

Currently compact requires Anthropic API key because bd calls the AI directly. This is backwards - we should provide tools (like all other bd commands) that let an AI agent perform the compaction. The agent decides what to keep/merge, not bd. Related to GH #243 complaint about API key requirement.


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)


Migration and onboarding for multi-repo

Create migration tools, wizards, and documentation to help users adopt multi-repo workflow, with special focus on OSS contributor onboarding and team adoption scenarios.


Test Agent Mail server failure scenarios

Verify graceful degradation across various failure modes.

Test Cases:
- Server never started
- Server crashes during operation
- Network partition (timeout)
- Server returns 500 error
- Invalid bearer token
- SQLite corruption

Acceptance Criteria:
- Agents continue working in all scenarios
- Clear log messages about degradation
- No crashes or data loss
- Beads JSONL remains consistent

File: tests/integration/test_mail_failures.py


Add tests for performFlush error handling in FlushManager

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

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

In cmd/bd/flush_manager.go:269, the performFlush method is flagged by unparam as always returning nil, indicating the error return value is never used.

Add tests to determine:
- Whether performFlush can actually return errors in failure scenarios
- If error return is needed, add tests for error cases (disk full, permission denied, etc.)
- If error return is not needed, refactor to remove unused return value
- Test full export vs incremental export error handling

This ensures proper error handling in the flush mechanism and removes dead code if the return value is unnecessary.

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


Replace Windows CI full test suite with smoke tests

## Problem

Windows CI tests consistently timeout at 30 minutes despite multiple optimization attempts:
- Split into parallel jobs (cmd vs internal) - still times out
- RAM disk for temp/cache - marginal improvement (~50%)
- RAM disk for workspace - breaks due to t.Chdir() incompatibility with ImDisk

Root cause: Windows I/O is fundamentally 20x slower than Linux:
- NTFS slow for small file operations
- Windows Defender scans every file access
- Git on Windows is 5-10x slower
- Process spawning is expensive

Linux tests complete in ~1.5 min with race detector. Windows takes 30+ min without.

## Current State

- Windows jobs have continue-on-error: true (don't block PRs)
- Tests timeout before completing, providing zero signal
- RAM disk experiments added complexity without solving the problem

## Solution: Smoke Tests Only

Replace full test suite with minimal smoke tests that verify Windows compatibility in < 2 minutes.

### What to Test
1. Binary builds - go build succeeds (already separate step)
2. Binary executes - bd version works
3. Init works - bd init creates valid database
4. Basic CRUD - create, list, show, update, close
5. Path handling - Windows backslash paths work

### Proposed CI Change

Replace test-windows-cmd and test-windows-internal with single smoke test job:
- Build bd.exe
- Run: bd version
- Run: bd init --quiet --prefix smoke
- Run: bd create --title "Windows smoke test" --type task
- Run: bd list
- Run: bd show smoke-001
- Run: bd update smoke-001 --status in_progress
- Run: bd close smoke-001

### Benefits
- Completes in < 2 minutes vs 30+ minute timeouts
- Provides actual pass/fail signal
- Verifies Windows binary works
- Removes RAM disk complexity
- Single job instead of two parallel jobs

### Files to Change
- .github/workflows/ci.yml - Replace test-windows-cmd and test-windows-internal jobs

### Migration Steps
1. Remove test-windows-cmd job
2. Remove test-windows-internal job
3. Add single test-windows job with smoke tests
4. Remove continue-on-error (tests should now pass reliably)
5. Clean up RAM disk remnants from previous attempts

### Context
- Parent issue: bd-5we (Use RAM disk for Windows CI tests)
- RAM disk approach proved insufficient
- This is the pragmatic solution after extensive experimentation


Update documentation for hash IDs and aliases

Update all documentation to explain hash-based IDs and aliasing system.

## Files to Update

### 1. README.md
Add section explaining hash IDs:
```markdown
## Issue IDs

Beads uses **hash-based IDs** for collision-free distributed issue tracking:

- **Hash ID**: `bd-af78e9a2` (8-char SHA256 prefix, immutable, globally unique)
- **Alias**: `#42` (sequential number, mutable, human-friendly)

### Using IDs
```bash
bd show bd-af78e9a2   # Use hash ID
bd show #42           # Use alias
bd show 42            # Use alias (shorthand)
```

### Why Hash IDs?
- **Collision-free**: Work offline without ID conflicts
- **Distributed**: No coordination needed between clones
- **Git-friendly**: Different IDs = different JSONL lines, fewer merge conflicts

### Aliases
Aliases are workspace-local shortcuts for hash IDs. They're:
- Automatically assigned on issue creation
- Reassigned deterministically on sync (if conflicts)
- Can be manually controlled with `bd alias` commands
```

### 2. AGENTS.md
Update agent workflow:
```markdown
## Hash-Based IDs (v2.0+)

Beads v2.0 uses hash-based IDs to eliminate collision problems:

**When creating issues**:
```bash
bd create "Fix bug" -p 1
# → Creates bd-af78e9a2 with alias #1
```

**When referencing issues**:
- In text: Use hash IDs (stable): "See bd-af78e9a2 for details"
- In CLI: Use aliases (readable): `bd update #42 --status done`

**After sync**:
- Alias conflicts resolved automatically (content-hash ordering)
- No ID collisions possible
- No remapping needed

**Migration from v1.x**:
```bash
bd migrate --hash-ids  # One-time migration
```
```

### 3. QUICKSTART.md (if exists)
Show alias usage in examples:
```bash
# Create issue (gets hash ID + alias)
bd create "Fix authentication bug" -p 1
# → Created bd-af78e9a2 (alias: #1)

# Reference by alias
bd show #1
bd update #1 --status in_progress
bd close #1 --reason "Fixed"
```

### 4. ADVANCED.md
Add section on hash ID internals:
```markdown
## Hash ID Generation

Hash IDs are generated deterministically:

```go
SHA256(title || description || timestamp || workspace_id)[:8]
```

**Collision probability**:
- 8 hex chars = 2^32 space = ~4 billion IDs
- Birthday paradox: 50% collision probability at ~65,000 issues
- For typical projects (<10,000 issues), collision risk is negligible

**Collision detection**:
If a hash collision occurs (extremely rare), beads:
1. Detects on insert (UNIQUE constraint)
2. Appends random suffix: `bd-af78e9a2-a1b2`
3. Retries insert

## Alias Conflict Resolution

When multiple clones assign same alias to different issues:

**Strategy**: Content-hash ordering (deterministic)
- Sort conflicting issue IDs lexicographically
- Lowest hash ID keeps the alias
- Others reassigned to next available aliases

**Example**:
```
Clone A: Assigns #42 to bd-a1b2c3d4
Clone B: Assigns #42 to bd-e5f6a7b8
After sync: bd-a1b2c3d4 keeps #42 (lower hash)
            bd-e5f6a7b8 gets #100 (next available)
```
```

### 5. MIGRATION.md (new file)
```markdown
# Migrating to Hash-Based IDs (v2.0)

## Overview
Beads v2.0 introduces hash-based IDs to eliminate collision problems. This is a **breaking change** requiring migration.

## Migration Steps

### 1. Backup
```bash
cp -r .beads .beads.backup
git commit -am "Pre-migration backup"
```

### 2. Run Migration
```bash
# Dry run first
bd migrate --hash-ids --dry-run

# Apply migration
bd migrate --hash-ids
```

### 3. Commit Changes
```bash
git add .beads/issues.jsonl
git commit -m "Migrate to hash-based IDs (v2.0)"
git push origin main
```

### 4. Coordinate with Collaborators
All clones must migrate before syncing:
1. Notify team: "Migrating to v2.0 on [date]"
2. All collaborators pull latest
3. All run `bd migrate --hash-ids`
4. All push changes
5. Resume normal work

## Rollback
```bash
# Restore backup
mv .beads.backup .beads
bd export  # Regenerate JSONL
git checkout .beads/issues.jsonl
```

## FAQ

**Q: Can I mix v1.x and v2.0 clones?**
A: No. All clones must be on same version.

**Q: Will my old issue IDs work?**
A: No, but aliases preserve the numbers: bd-1c63eb84 → #1

**Q: What happens to links like "see bd-cb64c226.3"?**
A: Migration updates all text references automatically.
```

## v2.0.0 (YYYY-MM-DD)

### Breaking Changes
- **Hash-based IDs**: Issues now use collision-free hash IDs (bd-af78e9a2)
  instead of sequential IDs (bd-1c63eb84, bd-9063acda)
- **Aliasing system**: Human-friendly aliases (#42) for hash IDs
- **Migration required**: Run `bd migrate --hash-ids` to convert v1.x databases

### Added
- `bd alias` command for manual alias control
- `bd migrate --hash-ids` migration tool
- Alias conflict resolution (deterministic, content-hash ordering)

### Removed
- ID collision detection and resolution (~2,100 LOC)
- `bd import --resolve-collisions` flag (no longer needed)

### Benefits
- ✅ Zero ID collisions in distributed workflows
- ✅ Simpler codebase (-1,350 net LOC)
- ✅ Better git merge behavior
- ✅ True offline-first operation
```

## Testing
- Build docs locally (if using doc generator)
- Check all links work
- Verify examples are correct
- Spellcheck

## Files to Create/Modify
- README.md (hash ID section)
- AGENTS.md (workflow updates)
- ADVANCED.md (internals)
- MIGRATION.md (new)
- CHANGELOG.md (v2.0 entry)

troubleshoot GH#278 daemon exits every few secs


Cache getMultiRepoJSONLPaths() result during sync to avoid redundant calls

From bd-xo6b code review: getMultiRepoJSONLPaths() is called 3x per sync cycle.

**Current behavior:**
daemon_sync.go calls getMultiRepoJSONLPaths() three times per sync:
- Line 505: Snapshot capture before pull
- Line 575: Merge/prune after pull
- Line 613: Base snapshot update after import

**Cost per call:**
- Config lookup (likely cached, but still overhead)
- Path construction: O(N) where N = number of repos
- String allocations: (N + 1) × filepath.Join() calls

**Total per sync:** 3N path constructions + 3 config lookups + 3 slice allocations

**Impact:**
- For N=3 repos: Negligible (< 1ms)
- For N=10 repos: Still minimal
- For N=100+ repos: Wasteful

**Solution:**
Call once at sync start, reuse result:

```go
func createSyncFunc(...) func() {
    return func() {
        // ... existing setup ...

        // Call once at start
        multiRepoPaths := getMultiRepoJSONLPaths()

        // Snapshot capture
        if multiRepoPaths != nil {
            for _, path := range multiRepoPaths {
                if err := captureLeftSnapshot(path); err != nil { ... }
            }
        }

        // ... later ...

        // Merge/prune - reuse same paths
        if multiRepoPaths != nil {
            for _, path := range multiRepoPaths { ... }
        }

        // ... later ...

        // Base snapshot update - reuse same paths
        if multiRepoPaths != nil {
            for _, path := range multiRepoPaths { ... }
        }
    }
}
```

**Files:**
- cmd/bd/daemon_sync.go:449-636 (createSyncFunc)

**Note:** This is a performance optimization, not a correctness fix. Low priority unless multi-repo usage scales significantly.

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)


Channel isolation test - beads

Resetting stale in_progress status from old executor run (13 days old)


Don't search parent directories for .beads databases

bd currently walks up the directory tree looking for .beads directories, which can find unrelated databases (e.g., ~/.beads). This causes confusing warnings and potential data pollution.

Should either:
1. Stop at git root (don't search above it)
2. Only use explicit BEADS_DB env var or local .beads
3. At minimum, don't search in home directory


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


Message System Improvements

Consolidate improvements to the bd message command including core functionality (message reading), reliability (timeouts), validation, and code quality refactoring


Fix import failure on missing parent issues

Import process fails atomically when JSONL references deleted parent issues. Implement hybrid solution: topological sorting + parent resurrection to handle deleted parents gracefully while maintaining referential integrity. See docs/import-bug-analysis-bd-3xq.md for full analysis.


Add tests for bd init --team wizard

Write integration tests for the team wizard:
- Test branch detection
- Test sync branch creation
- Test protected branch workflow
- Test auto-sync configuration


Help agents understand version changes with bd info --whats-new

**Problem** (from GH Discussion #239 by @maphew):
Weekly major versions mean agents need to adapt workflows, but currently there's no efficient way to communicate "what changed that affects you."

**Proposed solutions:**

1. **bd info --whats-new** - Show agent-actionable changes since last version
   ```
   Since v0.20.1:
   • Hash IDs eliminate collisions - remove ID coordination workarounds
   • Event-driven daemon (opt-in) - add BEADS_DAEMON_MODE=events
   • Merge driver auto-configured - conflicts rarer
   ```

2. **Version-aware bd onboard** - Detect version changes and show diff of agent-relevant changes

3. **AGENTS.md top section** - "🆕 Recent Changes (Last 3 Versions)" with workflow impacts

**Why agents need this:**
- Raw CHANGELOG is token-heavy and buried in release details
- Full bd onboard re-run wasteful if only 2-3 things changed
- Currently requires user to manually explain updates

**Related:** https://github.com/steveyegge/beads/discussions/239


Deletions pruning doesn't include results in JSON output

## Problem

When `bd compact --json` runs with deletions pruning, the prune results are silently discarded:

```go
// Only report if there were deletions to prune
if result.PrunedCount > 0 {
    if jsonOutput {
        // JSON output will be included in the main response
        return  // <-- BUG: results are NOT included anywhere
    }
    ...
}
```

## Location
`cmd/bd/compact.go:925-929`

## Impact
- JSON consumers don't know deletions were pruned
- No way to audit pruning via automation

## Fix
Return prune results and include in JSON output structure:

```json
{
  "success": true,
  "compacted": {...},
  "deletions_pruned": {
    "count": 5,
    "retention_days": 7
  }
}
```


bd find-duplicates - AI-powered duplicate detection

Find semantically duplicate issues.

Approaches:
1. Mechanical: Exact title/description matching
2. Embeddings: Cosine similarity (cheap, scalable)
3. AI: LLM-based semantic comparison (expensive, accurate)

Uses embeddings by default for >100 issues.

Files: cmd/bd/find_duplicates.go (new)


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 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 init resets metadata.json jsonl_export to beads.jsonl, ignoring existing issues.jsonl

When running 'bd init --prefix bd' in a repo that already has .beads/issues.jsonl, the init command overwrites metadata.json and sets jsonl_export back to 'beads.jsonl' instead of detecting and respecting the existing issues.jsonl file.

Steps to reproduce:
1. Have a repo with .beads/issues.jsonl (canonical) and metadata.json pointing to issues.jsonl
2. Delete beads.db and run 'bd init --prefix bd'
3. Check metadata.json - it now says jsonl_export: beads.jsonl

Expected: Init should detect existing issues.jsonl and use it.

Workaround: Manually edit metadata.json after init.


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.


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.


Integration Layer Implementation

Build the adapter layer that makes Agent Mail optional and non-intrusive.

Progress: bd-m9th (Python adapter library) completed with full test coverage. Next: bd-fzbg (update python-agent example with Agent Mail integration).

Document shared memory test isolation pattern in test_helpers.go

Tests were failing because :memory: creates a shared database across all tests. The fix is to use "file::memory:?mode=memory&cache=private" for test isolation.

Should document this pattern in test_helpers.go and potentially update newTestStore to use private memory by default.
