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 Keep it lightweight but catch more outdated hooks.


Consider using types.Status in merge package for type safety

The merge package uses string for status comparison (e.g., result.Status == closed, issue.Status == StatusTombstone). The types package defines Status as a type alias with validation. While the merge package needs its own Issue struct for JSONL flexibility, it could import and use types.Status for constants to get compile-time type checking. Current code: if left == closed || right == closed. Could be: if left == string(types.StatusClosed). This is low priority since string comparison works correctly.

bd doctor should check for multiple DBs, multiple JSONLs, daemon health


Implement `bd setup cursor` for Cursor IDE integration

Create a `bd setup cursor` command that integrates Beads workflow into Cursor IDE via .cursorrules file. Unlike Claude Code (which has hooks), Cursor uses a static rules file to provide context to its AI.


Git history fallback missing timeout - could hang on large repos

## Problem

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

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

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

## Fix
Add context with timeout to git commands:

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

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


Improve test coverage for internal/beads (48.1% → 70%)

The beads package is a core package with 48.1% coverage. As the primary package for issue management, it should have at least 70% coverage.

Current coverage: 48.1%
Target coverage: 70%


CONFIG.md docs for sync.require_confirmation_on_mass_delete missing threshold detail

The docs say 'if >50% of issues vanish' but the actual code (worktree.go:380) also requires '>5 issues existed before'. The docs should mention both conditions for completeness.


Refactor sqlite.go (2298 lines)

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


Hash-based IDs with aliasing system

Replace sequential auto-increment IDs (bd-1c63eb84, bd-9063acda) with content-hash based IDs (bd-af78e9a2) plus human-friendly aliases (#1, #2).

## Motivation
Current sequential IDs cause collision problems when multiple clones work offline:
- Non-deterministic convergence in N-way scenarios (bd-cbed9619.1, bd-e6d71828)
- Complex collision resolution logic (~2,100 LOC)
- UNIQUE constraint violations during import
- Requires coordination between workers

Hash-based IDs eliminate collisions entirely while aliases preserve human readability.

## Benefits
- ✅ Collision-free distributed ID generation
- ✅ Eliminates ~2,100 LOC of collision handling code
- ✅ Better git merge behavior (different IDs = different JSONL lines)
- ✅ True offline-first workflows
- ✅ Simpler auto-import (no remapping needed)
- ✅ Enables parallel CI/CD workers without coordination

## Design
- Canonical ID: bd-af78e9a2 (8-char SHA256 prefix of title+desc+timestamp+creator)
- Alias: #42 (auto-increment per workspace, mutable, display-only)
- CLI accepts both: bd show bd-af78e9a2 OR bd show #42
- JSONL stores hash IDs only (aliases reconstructed on import)
- Alias conflicts resolved via content-hash ordering (deterministic)

## Breaking Change
This is a v2.0 feature requiring migration. Provide bd migrate --hash-ids tool.

## Timeline
~9 weeks (Phase 1: Hash IDs 4w, Phase 2: Aliases 3w, Phase 3: Testing 2w)

## Dependencies
Should complete after bd-7c5915ae (cleanup validation) and before bd-710a4916 (CRDT).

Acceptance Criteria:
- Import and initialize adapter
- Check inbox before find_ready_work()
- Reserve issue before claim_task()
- Notify on status changes
- Release reservation on complete_task()
- Works identically when Agent Mail disabled
- No changes required to core Beads CLI

File: examples/python-agent/agent.py


Add --yes flag to bd doctor --fix

bd doctor --fix prompts for confirmation, which blocks automation (CI/CD, scripts, hooks).

Requirements:
1. Add --yes or -y flag to bd doctor command
2. When --yes is passed, skip confirmation prompts
3. Still log what's being fixed (don't go completely silent)


Issue 2 to reopen


Audit remaining cmd/bd files for error handling consistency

Extend ERROR_HANDLING_AUDIT.md to cover: daemon_sync.go, update.go, list.go, show.go, close.go, reopen.go, dep.go, label.go, comments.go, delete.go, compact.go, config.go, validate.go and other high-usage command files


Auto-routing and maintainer detection

Implement intelligent routing to automatically send new issues to correct repo based on user's maintainer vs contributor status, with discovered issues inheriting parent's source_repo.


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


Fix transaction conflict in TryResurrectParent

Integration test TestImportWithDeletedParent fails with 'database is locked' error when resurrection happens inside CreateIssue.

Root cause: TryResurrectParent calls conn.Get() and insertIssue() which conflicts with existing transaction in CreateIssue.

Error: failed to create tombstone for parent bd-parent: failed to insert issue: sqlite3: database is locked

Solution: Refactor resurrection to accept optional transaction parameter, use existing transaction when available instead of creating new connection.

Impact: Blocks resurrection from working in CreateIssue flow, only works in EnsureIDs (which may not have active transaction).


Fix bd init to bootstrap from sync-branch when configured

When sync-branch is configured in config.yaml, bd init should import from that branch instead of HEAD. Currently it reads HEAD:.beads/issues.jsonl which may be empty or stale when issues are on the sync branch. Location: cmd/bd/autoimport.go:97 checkGitForIssues()


Daemon performAutoImport should update jsonl_content_hash after import

The daemon's performAutoImport function was not updating jsonl_content_hash after successful import, unlike the CLI import path. This could cause repeated imports if the file hash and DB hash diverge.

Fix: Added hash update after validatePostImport succeeds, using repoKey for multi-repo support.


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 transaction boundaries for export metadata updates

## Problem
Metadata updates happen after export, but there's no transaction ensuring atomicity between:
1. JSONL file write (exportToJSONLWithStore)
2. Metadata update (updateExportMetadata)
3. Database mtime update (TouchDatabaseFile)

If process crashes between these steps, metadata will be inconsistent.

## Example Failure Scenario
```
1. Export to JSONL succeeds
2. [CRASH] Process killed before metadata update
3. Next export: "JSONL content has changed" error
4. User must run import to fix metadata
```

## Options

### Option 1: Tolerate Inconsistency (Current)
- Simple, no code changes
- Safe (worst case: need import before next export)
- Annoying for users if crashes are frequent

### Option 2: Add Write-Ahead Log
- Write metadata intent to temp file
- Complete operations
- Clean up temp file
- More complex, better guarantees

### Option 3: Store Metadata in JSONL Comments
- Add metadata as JSON comment in JSONL file
- Single atomic write
- Requires JSONL format change

### Option 4: Defensive Checks
- On startup, verify metadata matches JSONL
- Auto-fix if mismatch detected
- Simplest improvement

## Recommendation
Start with Option 4 (defensive checks), consider others if needed.

## Files
- cmd/bd/daemon_sync.go
- Possibly: cmd/bd/main.go (startup checks)

## Related
This is lower priority - current behavior is safe, just not ideal


Message System Improvements

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


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.

Import fails on same-content-different-ID instead of treating as update

## Problem

The importer still has rename detection (importer.go:482-500) that triggers when same content hash has different IDs. With hash IDs, this shouldn't happen, but when it does (test data, bugs, legacy data), the import fails:

```
failed to handle rename bd-ce75 -> bd-5a90: rename collision handling removed - should not occur with hash IDs
```

## Current Behavior

1. Importer finds same content hash with different IDs
2. Calls handleRename() (line 490)
3. handleRename() errors out (line 294): "rename collision handling removed"
4. Import fails

## Expected Behavior

Same content hash + different IDs should be treated as an **update**, not a rename:
- Keep existing ID (already in database)
- Update fields if incoming has newer timestamp
- Discard incoming ID (it's wrong - hash should have generated same ID)

## Impact

- Import fails on legitimate edge cases (test data, data corruption)
- Cryptic error message
- Blocks sync operations

## Fix

In handleRename() or import loop, instead of erroring:
```go
// Same content, different ID - treat as update
if incoming.UpdatedAt.After(existing.UpdatedAt) {
    existing.Status = incoming.Status
    // ... copy other fields
    s.UpdateIssue(ctx, existing)
}
result.Updated++
```

## Files
- internal/importer/importer.go:271-294 (handleRename)
- internal/importer/importer.go:482-500 (rename detection)

## Repro
Import JSONL with bd-ce75 and bd-5a90 (both "Test parent issue" but different content hashes).


Publish official devcontainer configuration

Devcontainer configuration implemented. Manual testing required in actual devcontainer environment (Codespaces or VSCode Remote Containers). All code changes complete, tests pass, linting clean.


Add tests for internal/importer package

Currently 0.0% coverage. Need tests for JSONL import logic including collision detection and resolution.


Add test files for internal/storage

The internal/storage package has no test files at all. This package provides the storage interface abstraction.

Current coverage: N/A (no test files)
Target: Add basic interface tests

RPC fast-fail: stat socket before dial, cap timeouts to 200ms

Eliminate 5s delay when daemon socket is missing by:
1. Add os.Stat(socketPath) check before dialing in TryConnect
2. Return (nil, nil) immediately if socket doesn't exist
3. Set default dial timeout to 200ms in TryConnect
4. Keep TryConnectWithTimeout for explicit health/status checks (1-2s)

This prevents clients from waiting through full timeout when no daemon is running.


Add --lock-timeout global flag

Add new global flag to control SQLite busy_timeout.

## Implementation
1. Add to cmd/bd/main.go:
   - `lockTimeout time.Duration` global variable
   - Register flag: `--lock-timeout=<duration>` (default 30s)

2. Add config support in internal/config/config.go:
   - `v.SetDefault("lock-timeout", "30s")`
   - Read from config.yaml if not set via flag

3. Pass timeout to sqlite.New() - see next task

## Acceptance Criteria
- `bd --lock-timeout=0 list` fails immediately if DB is locked
- `bd --lock-timeout=100ms list` waits max 100ms
- Config file setting works: `lock-timeout: 100ms`
- Default remains 30s for backward compatibility

Improve timestamp comparison readability in import

The timestamp comparison logic uses double-negative which can be confusing:

Current code:
if !incoming.UpdatedAt.After(existing.UpdatedAt) {
    // skip update
}

More readable:
if incoming.UpdatedAt.After(existing.UpdatedAt) {
    // perform update
} else {
    // skip (local is newer)
}

This is a minor refactor for code clarity.

bd validate - Comprehensive health check

Run all validation checks in one command.

Checks:
- Duplicates
- Orphaned dependencies
- Test pollution
- Git conflicts

Supports --fix-all for auto-repair.

Depends on bd-cbed9619.1, bd-0dcea000, bd-31aab707, bd-9826b69a.

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

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

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

This prevents stale artifacts from accumulating after daemon crashes.

→ Committing changes to sync branch 'beads-sync'...
Error committing to sync branch: failed to create worktree: failed to create worktree parent directory: mkdir /var/home/matt/dev/beads/fix-ci/.git: not a directory

**Problem Diagnosed**: The `bd sync` command was failing with "mkdir /var/home/matt/dev/beads/fix-ci/.git: not a directory" because it was being executed from the wrong directory.

**Root Cause**: The command was run from `/var/home/matt/dev/beads` (where the `fix-ci` worktree exists) instead of the main repository directory `/var/home/matt/dev/beads/main`. Since `fix-ci` is a git worktree with a `.git` file (not directory), the worktree creation logic failed when trying to create `<current_dir>/.git/beads-worktrees/<branch>`.

**Solution Verified**: Execute `bd sync` from the main repository directory:
```bash
cd main && bd sync --dry-run
```


Merge3Way public API does not expose TTL parameter

The public Merge3Way() function in merge.go does not allow callers to configure the tombstone TTL. It hard-codes the default via merge3WayWithTTL(). While merge3WayWithTTL() exists, it is unexported (lowercase). This means the CLI and tests cannot configure TTL at merge time. Use cases: testing with different TTL values, per-repository TTL configuration, debugging with short TTL, supporting --ttl flag in bd merge command (mentioned in design doc bd-zvg). Recommendation: Export Merge3WayWithTTL (rename to uppercase). Files: internal/merge/merge.go:77, 292-298


Refactor: extract common helpers in sync-branch hook checks

Code review of #532 fix identified duplication between checkSyncBranchHookCompatibility and checkSyncBranchHookQuick.

Suggested refactoring:
1. Extract getPrePushHookPath(path string) helper for git dir + hook path resolution
2. Extract extractHookVersion(hookContent string) helper for version parsing
3. Consider whether Warning for custom hooks is appropriate (vs OK with info message)
4. Document the intentional behavior difference between full check (Warning for custom) and quick check (OK for custom)

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

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

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

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

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

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

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

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

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

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


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

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


Add security tests for WriteFile permissions in doctor command

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

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

In cmd/bd/doctor/gitignore.go:98, os.WriteFile uses 0644 permissions, flagged by gosec G306 as potentially too permissive.

Add tests to verify:
- File is created with appropriate permissions (0600 or less)
- Existing file permissions are not loosened
- File ownership is correct
- Sensitive data handling if .gitignore contains secrets

This ensures .gitignore files are created with secure permissions to prevent unauthorized access.

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


Export deduplication breaks when JSONL and export_hashes table diverge

## Problem

The export deduplication feature (timestamp-only skipping) breaks when the JSONL file and export_hashes table get out of sync, causing exports to skip issues that aren't actually in the file.

## Symptoms

- `bd export` reports "Skipped 128 issue(s) with timestamp-only changes"
- JSONL file only has 38 lines but DB has 149 issues
- export_hashes table has 149 entries
- Auto-import doesn't trigger (hash matches despite missing data)
- Two repos on same commit show different issue counts

## Root Cause

shouldSkipExport() in autoflush.go compares current issue hash with stored export_hashes entry. If they match, it skips export assuming the issue is already in the JSONL.

This assumption fails when:
1. Git operations (pull, reset, checkout) change JSONL without clearing export_hashes
2. Manual JSONL edits or corruption
3. Import operations that modify DB but don't update export_hashes
4. Partial exports that update export_hashes but don't complete

## Impact

- **Critical data loss risk**: Issues appear to be tracked but aren't persisted to git
- Breaks multi-repo sync (root cause of today's debugging session)
- Auto-import fails to detect staleness (hash matches despite missing data)
- Silent data corruption (no error messages, just missing issues)

## Reproduction

1. Have DB with 149 issues, all in export_hashes table
2. Truncate JSONL to 38 lines (simulate git reset or corruption)
3. Run `bd export` - it skips 128 issues
4. JSONL still has only 38 lines but export thinks it succeeded

## Current Workaround

```bash
sqlite3 .beads/beads.db "DELETE FROM export_hashes"
bd export -o .beads/beads.jsonl
```

## Proposed Solutions

**Option 1: Verify JSONL integrity before skipping**
- Count lines in JSONL, compare with export_hashes count
- If mismatch, clear export_hashes and force full export
- Safe but adds I/O overhead

**Option 2: Hash-based JSONL validation**
- Store hash of entire JSONL file in metadata
- Before export, check if JSONL hash matches
- If mismatch, clear export_hashes
- More efficient, detects any JSONL corruption

**Option 3: Disable timestamp-only deduplication**
- Remove the feature entirely
- Always export all issues
- Simplest and safest, but creates larger git commits

**Option 4: Clear export_hashes on git operations**
- Add post-merge hook to clear export_hashes
- Clear on any import operation
- Defensive approach but may over-clear

## Recommended Fix

Combination of Options 2 + 4:
1. Store JSONL file hash in metadata after export
2. Check hash before export, clear export_hashes if mismatch
3. Clear export_hashes on import operations
4. Add `bd validate` check for JSONL/export_hashes sync

## Files Involved

- cmd/bd/autoflush.go (shouldSkipExport)
- cmd/bd/export.go (export with deduplication)
- internal/storage/sqlite/metadata.go (export_hashes table)

## Recovery Session (2025-10-29 21:30)

### What Happened
- Created 14 new hash ID issues (bd-f8b764c9 through bd-f8b764c9.1)
- bd sync appeared to succeed
- Canonical repo (~/src/beads): 162 issues in DB + JSONL ✓
- Secondary repo (fred/beads): Only 145 issues vs 162 in canonical ✗
- Both repos on same git commit but different issue counts!

### Bug Manifestation During Recovery

1. **Initial state**: fred/beads had 145 issues, 145 lines in JSONL, 145 export_hashes entries

2. **After git reset --hard origin/main**:
   - JSONL: 162 lines (from git)
   - DB: 150 issues (auto-import partially worked)
   - Auto-import failed with UNIQUE constraint error

3. **After manual import --resolve-collisions**:
   - DB: 160 issues
   - JSONL: Still 162 lines
   - export_hashes: 159 entries

4. **After bd export**:
   - **JSONL reduced to 17 lines!** ← The bug in action
   - export_hashes: 159 entries (skipped exporting 142 issues)
   - Silent data loss - no error message

5. **After clearing export_hashes and re-export**:
   - JSONL: 159 lines (missing 3 issues still)
   - DB: 159 issues
   - Still diverged from canonical

### The Bug Loop
Once export_hashes and JSONL diverge:
- Export skips issues already in export_hashes
- But those issues aren't actually in JSONL
- This creates corrupt JSONL with missing issues
- Auto-import can't detect the problem (file hash matches what was exported)
- Data is lost with no error messages

### Recovery Solution
Couldn't break the loop with export alone. Had to:
1. Copy .beads/beads.db from canonical repo
2. Clear export_hashes
3. Full re-export
4. Finally converged to 162 issues

### Key Learnings

1. **The bug is worse than we thought**: It can create corrupt exports (17 lines instead of 162!)

2. **Auto-import can't save you**: Once export is corrupt, auto-import just imports the corrupt data

3. **Silent failure**: No warnings, no errors, just missing issues

4. **Git operations trigger it**: git reset, git pull, etc. change JSONL without clearing export_hashes

5. **Import operations populate export_hashes**: Even manual imports update export_hashes, setting up future export failures

### Immediate Action Required

**DISABLE EXPORT DEDUPLICATION NOW**

This feature is fundamentally broken and causes data loss. Should be disabled until properly fixed.

Quick fix options:
- Set environment variable to disable feature
- Comment out shouldSkipExport check
- Always clear export_hashes before export
- Add validation that DB count == JSONL line count before allowing export

### Long-term Fix

Need Option 2 + 4 from proposed solutions:
1. Store JSONL file hash after every successful export
2. Before export, verify JSONL hash matches expected
3. If mismatch, log WARNING and clear export_hashes
4. Clear export_hashes on every import operation
5. Add git post-merge hook to clear export_hashes
6. Add `bd validate` command to detect divergence


Fix FOREIGN KEY constraint failures in AddComment and ApplyCompaction

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

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

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

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


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.


Update daemon commit logic for separate branch

Modify daemon to use worktree for commits when sync.branch configured.

Tasks:
- Update internal/daemon/server_export_import_auto.go
- Detect sync.branch configuration
- Ensure worktree exists before commit
- Sync JSONL to worktree
- Commit in worktree context
- Push to configured branch
- Fallback to current behavior if sync.branch not set
- Handle git errors (network, permissions, conflicts)

Estimated effort: 3-4 days


bd message: Add HTTP client timeout to prevent hangs

HTTP client in `sendAgentMailRequest` uses default http.Post with no timeout.

**Location:** cmd/bd/message.go:181

**Problem:**
- Can hang indefinitely if server is unresponsive
- No way to cancel stuck requests
- Poor UX in flaky networks

**Fix:**
```go
client := &http.Client{Timeout: 30 * time.Second}
resp, err := client.Post(url, "application/json", bytes.NewReader(reqBody))
```

**Impact:** Production reliability and security issue


Design migration path from deletions.jsonl to tombstones

Plan the migration from current deletions manifest to inline tombstones. Steps: 1) Read existing deletions.jsonl and convert to tombstones during import, 2) Continue reading deletions.jsonl for backward compat, 3) Stop writing to deletions.jsonl, 4) Eventually remove deletions.jsonl support. Consider version flags and deprecation warnings.


Improve test coverage for internal/compact (18.2% → 70%)

The compact package has only 18.2% test coverage. This is a core package handling issue compaction and should have at least 70% coverage.

Key functions needing tests:
- runCompactSingle (0%)
- runCompactAll (0%)
- runCompactRPC (0%)
- runCompactStatsRPC (0%)
- runCompactAnalyze (0%)
- runCompactApply (0%)
- pruneDeletionsManifest (0%)

Current coverage: 18.2%
Target coverage: 70%


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


Add performance optimization to hasJSONLChanged with mtime fast-path

hasJSONLChanged() reads entire JSONL file to compute SHA256 hash on every check. For large databases (50MB+), this is expensive and called frequently by daemon.

Optimization: Check mtime first as fast-path. Only compute hash if mtime changed. This catches git operations (mtime changes but content doesn't) while avoiding expensive hash computation in common case (mtime unchanged = content unchanged).

Performance impact: 99% of checks will use fast path, only git operations need slow path.


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

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

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

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

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

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

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

Related: bd-0rh (fixed similar issue for sync-branch)


Add unit tests for getLocalSyncBranch

The new getLocalSyncBranch() function in autoimport.go (bd-0is fix) has no dedicated unit tests.

Should test:
- Returns empty string when no config.yaml exists
- Returns empty string when config.yaml has no sync-branch key
- Returns value when sync-branch is set with double quotes
- Returns value when sync-branch is set with single quotes
- Returns value when sync-branch is set without quotes
- Returns BEADS_SYNC_BRANCH env var when set (takes precedence)
- Handles edge cases: empty file, whitespace-only lines, comments

Location: cmd/bd/autoimport_test.go


Refactor daemon local-only sync functions to reduce duplication

PR #433 added three new local-only sync functions (createLocalSyncFunc, createLocalExportFunc, createLocalAutoImportFunc) that are largely copy-paste of existing ones with git operations removed. Refactor to use a single implementation with a skipGit bool parameter or extract shared logic into helper functions to reduce ~200 lines of duplication.


URGENT: main branch has failing tests (syncbranch migration error)

The main branch has failing tests that are blocking CI for all PRs.

## Problem
All syncbranch_test.go tests failing with:
"migration external_ref_column failed: failed to create index on external_ref: sqlite3: SQL logic error: no such table: main.issues"

## Evidence
- Last 5 CI runs on main: ALL FAILED
- Tests fail locally on current main (bd6dca5)
- Affects: TestGet, TestSet, TestUnset in internal/syncbranch

## Impact
- Blocking all PR merges
- CI shows red for all branches
- Can't trust test results

## Root Cause
Migration order issue - trying to create index on external_ref column before the issues table exists, or before the external_ref column is added to the issues table.

## Quick Fix Needed
Need to investigate migration order in internal/storage/sqlite/migrations.go and ensure:
1. issues table is created first
2. external_ref column is added to issues table
3. THEN index on external_ref is created

This is CRITICAL - main should never have breaking tests.


Add import.orphan_handling config option

Add configuration option to control orphan handling behavior: 'strict' (fail on missing parent, current behavior), 'resurrect' (auto-resurrect from JSONL, recommended default), 'skip' (skip orphaned issues with warning), 'allow' (import orphans without validation). Update CONFIG.md documentation.


Add 'new' as alias for 'create' command


Wrap git operations in GitClient interface

Create internal/daemonrunner/git.go with GitClient interface (HasUpstream, HasChanges, Commit, Push, Pull). Default implementation using os/exec. Use in Syncer and Run loop for testability.


Benchmark git traffic reduction

Automated benchmark comparing git operations with/without Agent Mail.

Acceptance Criteria:
- Script that processes 50 issues
- Counts git operations (pull, commit, push)
- Generates comparison report
- Verifies ≥70% reduction
- Fails if regression detected

File: tests/benchmarks/git_traffic.py

Output: Without Agent Mail: 450 git operations, With Agent Mail: 135 git operations, Reduction: 70%

Implemented automated benchmark script with following features:
- Processes configurable number of issues (default 50)
- Compares git operations in two modes: git-only vs Agent Mail
- Generates detailed comparison report with statistics
- Exit code reflects pass/fail based on 70% reduction target
- Results: 98.5% reduction (200 ops → 3 ops) for 50 issues

Files created:
- tests/benchmarks/git_traffic.py (main benchmark script)
- tests/benchmarks/README.md (documentation)
- tests/benchmarks/git_traffic_50_issues.md (sample results)

The benchmark vastly exceeds the 70% target, showing 98.5% reduction.


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

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


Investigate performance issues in VS Code Copilot (Windows)

Beads unusable in Windows 11 VS Code Copilot chat with Sonnet 4.5.
Summary event happens every 3-4 turns, taking 3 minutes.
Copilot summarizes after ~125k tokens despite model supporting 1M.
Large context size of beads might be triggering aggressive summarization.
Need workaround or optimization for context size.


Extract daemon config functions to daemon_config.go


Consolidate ID generation and validation into ids.go

Extract ID logic into ids.go: ValidateIssueIDPrefix, GenerateIssueID, EnsureIDs. Move GetAdaptiveIDLength here. Unify single and bulk ID generation flows.


Document external_ref in content hash behavior

The content hash includes external_ref, which has implications that should be documented.

Current behavior:
- external_ref is included in content hash calculation (collision.go:158-160)
- Changing external_ref changes content hash
- This means: local issue → add external_ref → different hash

Implications:
- Local issue + external_ref addition = looks like 'new content'
- May not match by content hash in some scenarios
- Generally correct behavior, but subtle

Action items:
- Document in code comments
- Add to ARCHITECTURE.md or similar
- Add test demonstrating this behavior
- Consider if this is desired long-term

Detect and warn about outdated git hooks

Users may have outdated git hooks installed that reference removed flags (e.g., --resolve-collisions). bd should detect this and warn users to reinstall.


Add MCP server functions for repair commands

Expose new repair commands via MCP server for agent access:

Functions to add:
- beads_repair_deps()
- beads_detect_pollution()
- beads_validate()
- beads_resolve_conflicts() (when implemented)

Update integrations/beads-mcp/src/beads_mcp/server.py

See repair_commands.md lines 803-884 for design.

Implemented all three MCP server functions:

1. **repair_deps(fix=False)** - Find/fix orphaned dependencies
2. **detect_pollution(clean=False)** - Detect/clean test issues
3. **validate(checks=None, fix_all=False)** - Run comprehensive health checks

Changes:
- Added abstract methods to BdClientBase
- Implemented in BdCliClient (CLI execution)
- Added NotImplementedError stubs in BdDaemonClient (falls back to CLI)
- Created wrapper functions in tools.py
- Registered @mcp.tool decorators in server.py

All commands tested and working with --no-daemon flag.


Optimize test suite performance - cut runtime by 50%+

## Problem
Test suite takes ~20.8 seconds, with 95% of time spent in just 2 tests:
- TestHashIDs_MultiCloneConverge: 11.08s (53%)
- TestHashIDs_IdenticalContentDedup: 8.78s (42%)

Both tests in beads_hash_multiclone_test.go perform extensive Git operations (bare repos, multiple clones, sync rounds).

## Goal
Cut total test time by at least 50% (to ~10 seconds or less).

## Analysis
Tests already have some optimizations:
- --shared --depth=1 --no-tags for fast cloning
- Disabled hooks, gc, fsync
- Support -short flag

## Impact
- Faster development feedback loop
- Reduced CI costs and time
- Better developer experience


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._


Integrate beads-merge tool by @neongreen

**Context**: @neongreen built a production-ready 3-way merge tool for JSONL files that works with both Git and Jujutsu. This is superior to our planned bd resolve-conflicts because it prevents conflicts proactively instead of resolving them after the fact.

**Tool**: https://github.com/neongreen/mono/tree/main/beads-merge

**What it does**:
- 3-way merge of JSONL files (base, left, right)
- Field-level merging (titles, status, priority, etc.)
- Smart dependency merging (union + dedup)
- Conflict markers for unresolvable conflicts
- Exit code 1 for conflicts (standard)

**Integration options**:

1. **Recommend (minimal effort)** - Document in AGENTS.md + TROUBLESHOOTING.md
2. **Bundle binary** - Include in releases (cross-platform builds)
3. **Port to Go** - Reimplement in bd codebase
4. **Auto-install hook** - During bd init, offer to install merge driver

**Recommendation**: Start with option 1 (document), then option 2 (bundle) once proven.

**Related**: bd-5f483051 (bd resolve-conflicts - can close as superseded)

Created GitHub issue to discuss integration approach with @neongreen: https://github.com/neongreen/mono/issues/240

Awaiting their preference on:
1. Vendor with attribution (fastest)
2. Extract as importable module (best long-term)
3. Keep as separate tool (current state)

Next: Wait for response before proceeding with integration.

UPDATE 2025-11-06: @neongreen gave permission to vendor! Quote: "I switched from beads to my own thing (tk) so I'm very happy to give beads-merge away — feel free to move it into the beads repo and I will point mono's readme to beads"

Next: Vendor beads-merge with full attribution


bd sync corrupts issues.jsonl in multi-clone environments

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

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

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

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

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

Extract computeJSONLHash helper to eliminate code duplication

SHA256 hash computation is duplicated in 3 places:
- cmd/bd/integrity.go:50-52
- cmd/bd/sync.go:611-613

Test all core bd commands in WASM for feature parity

Comprehensive testing of bd-wasm against native bd:
- Test all CRUD operations (create, update, show, close)
- Test dependency management (dep add, dep tree)
- Test sync operations (sync, import, export)
- Verify JSONL output matches native bd
- Run existing Go test suite in WASM if possible
- Benchmark performance (should be within 2x of native)


Event-driven daemon architecture

Replace 5-second polling sync loop with event-driven architecture that reacts instantly to changes. Eliminates stale data issues while reducing CPU ~60%. Key components: FileWatcher (fsnotify), Debouncer (500ms), RPC mutation events, optional git hooks. Target latency: <500ms (vs 5000ms). See event_driven_daemon.md for full design.

Production-ready after 3 critical fixes (commit 349b892):
- Skip redundant imports (mtime check prevents self-trigger loops)
- Add server.Stop() in serverErrChan case (clean shutdown)
- Fallback ticker (60s) when watcher unavailable (ensures remote sync)

Ready to make default after integration test (bd-1f4086c5.1) passes.


Imperator clone on beads-sync branch causes bd sync failures


Design tombstone storage format

Define the JSON schema for tombstone records. Options: minimal (id, deleted_at, deleted_by, expires_at) vs full preservation (keep all original fields). Trade-offs: storage size vs audit trail. Consider: should tombstones be distinguishable from regular issues by status field or separate record type?


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

## References
- Related to bd-0dcea000 (immediate fix)
- See beads_nway_test.go for failing N-way tests


Run bd doctor at end of bd init to verify setup

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


Post-merge hook silently fails on JSONL conflicts, poor UX

When git pull results in merge conflicts in .beads/issues.jsonl, the post-merge hook runs 'bd sync --import-only' which fails, but stderr was redirected to /dev/null. User only saw generic warning.

Fixed by capturing and displaying the actual error output, so users see 'Git conflict markers detected' message immediately.


bd message: Refactor duplicated error messages


Run final validation and cleanup checks

Final validation pass to ensure all cleanup objectives met and no regressions introduced.

Validation checklist:
1. Dead code verification: `go run golang.org/x/tools/cmd/deadcode@latest -test ./...`
2. Test coverage: `go test -cover ./...`
3. Build verification: `go build ./cmd/bd/`
4. Linting: `golangci-lint run`
5. Integration tests
6. Metrics verification
7. Git clean check

Final metrics to report:
- LOC removed: ~____
- Files deleted: ____
- Files created: ____
- Test coverage: ____%
- Build time: ____ (before/after)
- Test run time: ____ (before/after)

Impact: Confirms all cleanup objectives achieved successfully

## Validation Results

**Dead Code:** ✅ Found and removed 1 unreachable function (`DroppedEventsCount`)
**Tests:** ✅ All pass
**Coverage:**
- Main: 39.6%
- cmd/bd: 20.2%
- Created follow-up issues (bd-85487065 through bd-bc2c6191) to improve coverage

**Build:** ✅ Clean
**Linting:** 73 issues (up from 34 baseline)
- Increase due to unused functions from refactoring
- Need cleanup in separate issue

**Integration Tests:** ✅ All pass
**Metrics:** 56,464 LOC across 193 Go files
**Git:** 2 files modified (deadcode fix + auto-synced JSONL)

## Follow-up Issues Created
- bd-85487065: Add tests for internal/autoimport (0% coverage)
- bd-0dcea000: Add tests for internal/importer (0% coverage)
- bd-4d7fca8a: Add tests for internal/utils (0% coverage)
- bd-6221bdcd: Improve cmd/bd coverage (20.2% -> target higher)
- bd-bc2c6191: Improve internal/daemon coverage (22.5% -> target higher)


Add TestThreeCloneCollision for regression protection

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

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

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

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


Use external_ref as primary matching key for import updates

Enable re-syncing from external systems (Jira, GitHub, Linear) by using external_ref as the primary matching key during imports. Currently imports treat any content change as a collision, making it impossible to sync updates from external systems without creating duplicates.

See GH #142 for detailed proposal and implementation plan.

Key changes needed:
1. Add findByExternalRef() query function
2. Update DetectCollisions() to match by external_ref first
3. Update import_shared.go to update existing issues when external_ref matches
4. Add index on external_ref for performance
5. Preserve local issues (no external_ref) from being overwritten

This enables hybrid workflows: import external backlog, break down with local tasks, re-sync anytime.

## Code Review Complete ✅

**Overall Assessment**: EXCELLENT - Production ready

### Implementation Quality
- ✓ Clean architecture with proper interface extension
- ✓ Dual backend support (SQLite + Memory)
- ✓ Smart matching priority: external_ref → ID → content hash
- ✓ O(1) lookups with database index
- ✓ Timestamp-based conflict resolution
- ✓ Comprehensive test coverage (11 test cases)

### Follow-up Issues Filed
High Priority (P2):
- bd-897a: Add UNIQUE constraint on external_ref column
- bd-7315: Add validation for duplicate external_ref in batch imports

Medium Priority (P3):
- bd-f9a1: Add index usage verification test
- bd-3f6a: Add concurrent import race condition tests

Low Priority (P4):
- bd-e166: Improve timestamp comparison readability
- bd-9e23: Optimize Memory backend with index
- bd-537e: Add external_ref change tracking
- bd-df11: Add import metrics
- bd-9f4a: Document external_ref in content hash

### Key Features
✅ External systems (Jira, GitHub, Linear) can re-sync without duplicates
✅ Hybrid workflows: import external backlog, add local tasks, re-sync anytime
✅ Local issues protected from being overwritten
✅ Timestamp checking ensures only newer updates applied
✅ Performance optimized with database index

**Confidence Level**: 95% - Ship it! 🚀


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
  }
}
```


Production Readiness (Optional)

Enable multi-machine deployments with containerization and monitoring.


Add MCP functions for repair commands

Block direct status update to tombstone in UpdateIssue

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

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

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

Add validation to reject status=tombstone in updates.


Add bd doctor --fix flag to automatically repair issues

Implement a --fix flag for bd doctor that can automatically repair detected issues.

Requirements:
- Add --fix flag to bd doctor command
- Show all fixable issues and prompt for confirmation before applying fixes
- Organize fix implementations under doctor/fix/<type_of_fix>.go
- Each fix type should have its own file (e.g., doctor/fix/hooks.go, doctor/fix/sync.go)
- Display what will be fixed and ask user to confirm (Y/n) before proceeding
- Support fixing issues like:
  - Missing or broken git hooks
  - Sync problems with remote
  - File permission issues
  - Any other auto-repairable issues doctor detects

Implementation notes:
- Maintain separation between detection (existing doctor code) and repair (new fix code)
- Each fix should be idempotent and safe to run multiple times
- Provide clear output about what was fixed
- Log any fixes that fail with actionable error messages


bd jira sync command

Add a built-in bd command for Jira synchronization.

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

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

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

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

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


Multi-clone collision resolution testing and documentation

Epic to track improvements to multi-clone collision resolution based on ultrathinking analysis of-3d844c58 and [deleted:bd-71107098].

Current state:
- 2-clone collision resolution is SOUND and working correctly
- Hash-based deterministic collision resolution works
- Test fails due to timestamp comparison, not actual logic issues

Work needed:
1. Fix TestTwoCloneCollision to compare content not timestamps
2. Add TestThreeCloneCollision for regression protection
3. Document 3-clone ID non-determinism as known behavior


Implement tombstone types and schema migration

Add tombstone fields to Issue struct (deleted_at, deleted_by, delete_reason, original_type), add StatusTombstone constant, create SQLite migration for new columns. Per design bd-2m7.


Test graceful degradation when server unavailable

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

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

Success Metric: Zero functional difference when Agent Mail unavailable

Install and test MCP Agent Mail locally

Install MCP Agent Mail on a single development machine and verify basic functionality.

Acceptance Criteria:
- Server installed via one-line installer
- Server running on port 8765
- Can register a project via HTTP
- Can register an agent identity
- Web UI accessible at /mail

Tested local installation. Server runs on port 8765, web UI works. MCP API tool execution has errors - needs debugging. See /tmp/bd-muls-report.md for details.


Update import/export to handle tombstones

Modify importer to read tombstones from issues.jsonl and legacy deletions.jsonl. Modify exporter to write tombstones. Filter tombstoned issues during import. Per design bd-dli.


Test basic bd commands in WASM (init, create, list)

Compile and verify basic bd functionality works in WASM:
- Test bd init --quiet
- Test bd create with simple issue
- Test bd list --json output
- Verify SQLite database creation and queries work
- Document any runtime issues or workarounds needed


Add index usage verification test for external_ref lookups

Currently we test that idx_issues_external_ref index exists, but we don't verify that it's actually being used by the query planner.

Proposed solution:
- Add test using EXPLAIN QUERY PLAN
- Verify that 'SEARCH TABLE issues USING INDEX idx_issues_external_ref' appears in plan
- Ensures O(1) lookup performance is maintained

Fix TestTwoCloneCollision timeout


Add template support for issue creation

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

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

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

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


Remove unused global daemon infrastructure (internal/daemonrunner/)

The internal/daemonrunner/ package (1,468 LOC) contains the old global daemon implementation that is no longer used. We now use per-workspace daemons.

Deadcode analysis shows all these functions are unreachable:
- Daemon.Start, runGlobalDaemon, setupLock
- validateSingleDatabase, validateSchemaVersion
- registerDaemon, unregisterDaemon
- validateDatabaseFingerprint
- Full git client implementation (NewGitClient, HasUpstream, HasChanges, Commit, Push, Pull)
- Helper functions: isGitRepo, gitHasUpstream, gitHasChanges, gitCommit

The entire package appears unused since switching to per-workspace daemon architecture.

Files to remove:
- daemon.go (9,436 bytes)
- git.go (3,510 bytes)
- sync.go (6,401 bytes)
- fingerprint.go (2,076 bytes)
- process.go (3,332 bytes)
- rpc.go (994 bytes)
- config.go (486 bytes)
- logger.go (1,579 bytes)
- flock_*.go (platform-specific file locking)
- signals_*.go (platform-specific signal handling)
- All test files

Total cleanup: ~1,500 LOC


Add migration registry and simplify New()

Create migrations.go with Migration type and registry. Change New() to: openDB -> initSchema -> RunMigrations(db). This removes 8+ separate migrate functions from New().


Add cancellation and timeout tests

Add comprehensive tests for context cancellation and timeout behavior.

## Context
Part of context propagation work. Validates that bd-rtp and bd-yb8 work correctly.

## Test Coverage Needed

### 1. Cancellation Tests
- [ ] Import operation cancelled mid-stream
- [ ] Export operation cancelled mid-stream
- [ ] Database query cancelled during long operation
- [ ] No corruption after cancellation
- [ ] Proper cleanup (defers execute, connections closed)

### 2. Timeout Tests
- [ ] Operations respect context deadlines
- [ ] Appropriate error messages on timeout
- [ ] State remains consistent after timeout

### 3. Signal Handling Tests
- [ ] SIGINT (Ctrl+C) triggers cancellation
- [ ] SIGTERM triggers graceful shutdown
- [ ] Multiple signals handled correctly

## Implementation Approach
```go
func TestImportCancellation(t *testing.T) {
    ctx, cancel := context.WithCancel(context.Background())

    // Start import in goroutine
    go func() {
        err := runImport(ctx, largeFile)
        assert.Error(err, context.Canceled)
    }()

    // Cancel after short delay
    time.Sleep(100 * time.Millisecond)
    cancel()

    // Verify database integrity
    assertDatabaseConsistent(t, store)
}
```

## Files to Create/Update
- cmd/bd/import_test.go - cancellation tests
- cmd/bd/export_test.go - cancellation tests
- internal/storage/sqlite/*_test.go - context timeout tests

## Acceptance Criteria
- [ ] All critical operations have cancellation tests
- [ ] Tests verify database integrity after cancellation
- [ ] Signal handling tested (if feasible)
- [ ] Test coverage >80% for context paths

bd validate - Comprehensive health check

Run all validation checks in one command.

Checks:
- Duplicates
- Orphaned dependencies
- Test pollution
- Git conflicts

Supports --fix-all for auto-repair.

Depends on bd-cbed9619.1, bd-0dcea000, bd-31aab707, bd-9826b69a.

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


Extract batch operations to batch_ops.go

Move validateBatchIssues, generateBatchIDs, bulkInsertIssues, bulkRecordEvents, bulkMarkDirty, CreateIssues to batch_ops.go


Add 'When to use daemon mode' decision tree to daemon.md

**Problem:**
Users (especially local-only developers) see daemon-related messages but don't understand:
- What daemon mode does (git sync automation)
- Whether they need it
- Why they see "daemon_unsupported" messages

Related to issue #349 item #3.

**Current state:**
commands/daemon.md explains WHAT daemon does but not WHEN to use it.

**Proposed addition:**
Add a "When to Use Daemon Mode" section after line 20 in commands/daemon.md with clear decision criteria:

**✅ You SHOULD use daemon mode if:**
- Working in a team with git remote sync
- Want automatic commit/push of issue changes
- Need background auto-sync (5-second debounce)
- Making frequent bd commands (performance benefit)

**❌ You DON'T need daemon mode if:**
- Solo developer with local-only tracking
- Working in git worktrees (use --no-daemon)
- Running one-off commands/scripts
- Debugging database issues

**Local-only users:** Direct mode is perfectly fine. Daemon mainly helps with git sync automation. You can use `bd sync` manually when needed.

**Files to modify:**
- commands/daemon.md (add section after line 20)


Add validation and documentation for metadata key format

## Issues

### 1. No validation that keySuffix doesn't contain separator
```go
if keySuffix != "" {
    hashKey += ":" + keySuffix  // ❌ What if keySuffix contains ":"?
}
```

Add validation:
```go
if strings.Contains(keySuffix, ":") {
    return fmt.Errorf("keySuffix cannot contain ':' separator")
}
```

### 2. Inconsistent keySuffix semantics
Empty string means "global", non-empty means "scoped". Better to always pass explicit key:
```go
const (
    SingleRepoKey = "."
    // Multi-repo uses source_repo identifier
)
```

### 3. Metadata key format not documented
Need to document:
- `last_import_hash` - single-repo mode
- `last_import_hash:<repo_key>` - multi-repo mode
- `last_import_time` - when last import occurred
- `last_import_mtime` - fast-path optimization

Add to internal/storage/sqlite/schema.go or docs/


GH#243: Recurring stale daemon.lock causes 5s delays

User reports daemon.lock keeps becoming stale after running Claude with beads.

Symptom:
- bd ready takes 5 seconds (exact)
- daemon.lock exists but socket is missing
- bd daemons killall temporarily fixes it
- Problem recurs after using beads with AI agents

User on v0.22.0, Macbook M2, 132 issues (89 closed)

Hypothesis: Daemon is crashing or exiting uncleanly during agent sessions, leaving stale lock file.

Need to:
1. Add crash logging to daemon to understand why it's exiting
2. Improve cleanup on daemon exit (ensure lock is always removed)
3. Add automatic stale lock detection/cleanup
4. Consider making daemon more resilient to crashes

Oracle analysis complete. Converting to epic with 5 focused sub-issues:
1. RPC fast-fail with socket stat + short timeouts (P0)
2. Standardize daemon detection with lock probe (P1)
3. Crash recovery improvements (P2)
4. Self-heal stale artifacts (P2)
5. Diagnostics and debugging (P3)


bd-hv01: Refactor snapshot management into dedicated module

Problem: Snapshot logic is scattered across deletion_tracking.go. Would benefit from abstraction with SnapshotManager type.

Benefits: cleaner separation of concerns, easier to test in isolation, better encapsulation, could add observability/metrics.

Suggested improvements: add magic constants, track merge statistics, better error messages.

Files: cmd/bd/deletion_tracking.go (refactor into new snapshot_manager.go)


Update documentation for merge driver auto-config

Update documentation to reflect the new merge driver auto-configuration during `bd init`.

**Files to update:**
- README.md - Mention merge driver setup in initialization section
- AGENTS.md - Update onboarding section about merge driver
- Possibly QUICKSTART.md

**Content:**
- Explain what the merge driver does
- Show --skip-merge-driver flag usage
- Manual installation steps for post-init setup


bd message: Improve type safety with typed parameter structs


Multi-repo hydration layer

Build core infrastructure to hydrate database from N repos (N≥1), with smart caching via file mtime tracking and routing writes to correct JSONL based on source_repo metadata.


Add UNIQUE constraint on external_ref column

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

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

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

Related: bd-1022


Blocking issue


Fix bd doctor to recommend issues.jsonl as canonical (not beads.jsonl)


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

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

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

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

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


Jira import/export integration

Add ability to import issues from Jira and export beads issues to Jira. See GitHub discussion #430 for user request.

**Background**: User @kaihendry configured jira.* settings but found bd sync doesn't sync with Jira - only with git. The config namespace exists but the integration doesn't.

**Existing infrastructure**:
- external_ref field for linking to external systems
- Import logic matches by external_ref first (priority over ID matching)
- Config namespace jira.* documented in CONFIG.md
- GitHub import example (examples/github-import/gh2jsonl.py) provides pattern

**Schema mapping challenges**:
- Jira workflows are highly customizable (status mapping)
- Jira has more field types (components, versions, custom fields)
- Two-way sync needs conflict resolution
- Jira Cloud vs Server/Data Center have different APIs

**Approach**: Phased implementation starting with import, then export, then bidirectional sync.


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)
2. **No JSONL file found** (line 267-277)
3. **JSONL stat fails** (line 279-282)

## Fix

Return errors for abnormal conditions:

```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


Create deployment scripts for GCP

Automated provisioning scripts for GCP Compute Engine deployment.

Acceptance Criteria:
- Terraform/gcloud scripts
- Static IP allocation
- Firewall rules
- NGINX reverse proxy config
- TLS setup (Let's Encrypt)
- Systemd service file

File: deployment/agent-mail/gcp/


Mass deletion logging for forensics

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

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

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

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


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

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

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

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

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


Fix auto-import creating duplicates instead of updating issues

ROOT CAUSE: server_export_import_auto.go line 221 uses ResolveCollisions: true for ALL auto-imports. This is wrong.

Problem:
- ResolveCollisions is for branch merges (different issues with same ID)
- Auto-import should UPDATE existing issues, not create duplicates
- Every git pull creates NEW duplicate issues with different IDs
- Two agents ping-pong creating endless duplicates

Evidence:
- 31 duplicate groups found (bd duplicates)
- bd-236-246 are duplicates of bd-224-235
- Both agents keep pulling and creating more duplicates
- JSONL file grows endlessly with duplicates

The Fix:
Change checkAndAutoImportIfStale in server_export_import_auto.go:
- Remove ResolveCollisions: true (line 221)
- Use normal import logic that updates existing issues by ID
- Only use ResolveCollisions for explicit bd import --resolve-collisions

Impact: Critical - makes beads unusable for multi-agent workflows


Remove misleading placeholder 'bd merge' command from duplicates output

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

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

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

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

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

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

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


bd-hv01: Missing cleanup of .merged temp file on failure

Problem: deletion_tracking.go:49 creates tmpMerged file but does not clean up on failure, causing disk space leak and potential interference with subsequent syncs.

Fix: Add defer os.Remove(tmpMerged) after creating temp file path.

Files: cmd/bd/deletion_tracking.go:38-89


Import validation falsely reports data loss on collision resolution

## Problem

Post-import validation reports 'data loss detected!' when import count reduces due to legitimate collision resolution.

## Example

```
Import complete: 1 created, 8 updated, 142 unchanged, 19 skipped, 1 issues remapped
Post-import validation failed: import reduced issue count: 165 → 164 (data loss detected!)
```

This was actually successful collision resolution (bd-70419816 duplicated → remapped to-70419816), not data loss.

## Impact

- False alarms waste investigation time
- Undermines confidence in import validation
- Confuses users/agents about sync health

## Solution

Improve validation to distinguish:
- Collision-resolution merges (expected count reduction)
- Actual data loss (unexpected disappearance)

Track remapped issue count and adjust expected post-import count accordingly.


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)


Create npm package structure for bd-wasm

Set up npm package for distribution:
- Create package.json with bd-wasm name
- Bundle bd.wasm + wasm_exec.js
- Create CLI wrapper (bin/bd) that invokes WASM
- Add installation scripts if needed
- Configure package for Claude Code Web sandbox compatibility


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.


Test simple issue


Remove Daemon Storage Cache

The daemon's multi-repo storage cache is the root cause of stale data bugs. Since global daemon is deprecated, we only ever serve one repository, making the cache unnecessary complexity. This epic removes the cache entirely for simpler, more reliable direct storage access.


Implement backup functionality for reset

Add backup capability that can be used by reset command.

## Functionality
- Copy .beads/ to .beads-backup-{timestamp}/
- Timestamp format: YYYYMMDD-HHMMSS
- Preserve file permissions
- Return backup path for user feedback

## Location
`internal/reset/backup.go` - keep with reset package for now (YAGNI)

## Interface
```go
func CreateBackup(beadsDir string) (backupPath string, err error)
```

## Notes
- Simple recursive file copy, no compression needed
- Error if backup dir already exists (unlikely with timestamp)
- Backup directories SHOULD be gitignored
- Add `.beads-backup-*/` pattern to .beads/.gitignore template in doctor package
- Consider: ListBackups() for future `bd backup list` command (not for this PR)


Improve test coverage for internal/daemon (27.3% → 60%)

The daemon package has only 27.3% test coverage. The daemon is critical for background operations and reliability.

Key areas needing tests:
- Daemon autostart logic
- Socket handling
- PID file management
- Health checks

Current coverage: 27.3%
Target coverage: 60%


Design tombstone merge semantics

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


mergeTombstones does not handle empty DeletedAt timestamps

The mergeTombstones() function uses isTimeAfter() to compare deleted_at timestamps, but does not handle the edge case where one or both tombstones have empty DeletedAt fields. Current behavior with isTimeAfter() semantics: empty string returns false when compared, which means if left.DeletedAt is empty, right wins. If both are empty, behavior depends on isTimeAfter tie-breaker. This should be explicitly handled with a comment or validation. Recommendation: Add explicit handling or documentation for invalid tombstones. Files: internal/merge/merge.go:448-456


getLocalSyncBranch YAML parsing is fragile

The getLocalSyncBranch() function in autoimport.go uses a simple line-by-line YAML parser that could fail on:
- Indented sync-branch: (nested in a section)
- Comments containing sync-branch:
- Multi-line values
- Values with special characters

Current implementation at autoimport.go:161-172 does:
```go
for _, line := range strings.Split(string(data), "\n") {
    line = strings.TrimSpace(line)
    if strings.HasPrefix(line, "sync-branch:") {
        value := strings.TrimPrefix(line, "sync-branch:")
        ...
    }
}
```

The reason we can't use viper's cached config is that it's initialized at process startup from the main repo's CWD, not from the current directory at runtime. This causes issues in tests where t.Chdir() changes the directory.

Options:
1. Accept the limitation (sync-branch must be top-level, unquoted)
2. Use a proper YAML library (gopkg.in/yaml.v3) to parse just this value
3. Refactor config package to support re-initialization per directory


Fix validatePreExport to use content hash instead of mtime

validatePreExport() in integrity.go:70 still uses isJSONLNewer() (mtime-based), creating inconsistent behavior. Auto-import correctly uses hasJSONLChanged() (hash-based) but export validation still uses the old mtime approach. This can cause false positive blocks after git operations.

Fix: Replace isJSONLNewer() call with hasJSONLChanged() in validatePreExport().

Impact: Without this fix, the bd-khnb solution is incomplete - we prevent resurrection but still have export blocking issues.


Run final validation and cleanup checks

Final validation pass to ensure all cleanup objectives met and no regressions introduced.

Validation checklist:
1. Dead code verification: `go run golang.org/x/tools/cmd/deadcode@latest -test ./...`
2. Test coverage: `go test -cover ./...`
3. Build verification: `go build ./cmd/bd/`
4. Linting: `golangci-lint run`
5. Integration tests
6. Metrics verification
7. Git clean check

Final metrics to report:
- LOC removed: ~____
- Files deleted: ____
- Files created: ____
- Test coverage: ____%
- Build time: ____ (before/after)
- Test run time: ____ (before/after)

Impact: Confirms all cleanup objectives achieved successfully

## Validation Results (Oct 31, 2025)

**Dead Code:** ✅ Removed 5 unreachable functions (~200 LOC)
- computeIssueContentHash, shouldSkipExport (autoflush.go)
- addDependencyUnchecked, removeDependencyIfExists (dependencies.go)
- isUniqueConstraintError (util.go)

**Tests:** ✅ All pass
**Coverage:**
- Main package: 39.6%
- cmd/bd: 19.5%
- internal/daemon: 37.8%
- internal/storage/sqlite: 58.1%
- internal/rpc: 58.6%

**Build:** ✅ Clean (24.5 MB binary)
**Linting:** 247 issues (mostly errcheck on defer/Close statements)
**Integration Tests:** ✅ All pass
**Metrics:** 55,622 LOC across 200 Go files
**Git:** 3 files modified (dead code removal)


Optimize --sandbox mode: skip FlushManager

When `--sandbox` mode is enabled, skip FlushManager creation entirely.

## Current Behavior
`main.go:561` always creates FlushManager:
```go
flushManager = NewFlushManager(autoFlushEnabled, getDebounceDuration())
```

Even with `--sandbox` (which sets `noAutoFlush=true`), the FlushManager goroutine is still running.

## Proposed Change
```go
// Only create FlushManager if we might actually need it
if !sandboxMode && autoFlushEnabled {
    flushManager = NewFlushManager(true, getDebounceDuration())
}
```

## Handle nil FlushManager
Update PersistentPostRun to handle nil:
```go
if flushManager != nil && !skipFinalFlush {
    if err := flushManager.Shutdown(); err != nil {
        // ...
    }
}
```

## Synchronous Export Fallback
When sandbox mode + write operation occurs, do synchronous export:
```go
if sandboxMode && isDirty {
    performSynchronousExport()
}
```

## Also: Default lock-timeout to 100ms in sandbox mode
In PersistentPreRun, when sandboxMode is detected:
```go
if sandboxMode {
    noDaemon = true
    noAutoFlush = true
    noAutoImport = true
    if lockTimeout == 30*time.Second { // Not explicitly set
        lockTimeout = 100 * time.Millisecond
    }
}
```

Testing & Validation

Ensure reliability through comprehensive testing.

Completed comprehensive Agent Mail test coverage analysis and implementation.

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

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

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

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

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

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


Auto-repair stale merge driver configs with invalid placeholders

Old bd versions (<0.24.0) installed merge driver with invalid placeholders %L %R instead of %A %B. Add detection to bd doctor --fix: check if git config merge.beads.driver contains %L or %R, auto-repair to 'bd merge %A %O %A %B'. One-time migration for users who initialized with old versions.


Benchmark Helper Functions

Extend existing benchmark helpers in internal/storage/sqlite/bench_helpers_test.go (or create if organizing separately).

Existing helper (in compact_bench_test.go):
- setupBenchDB(tb) - Creates temp SQLite database with basic config
  * Used by compact and cycle benchmarks
  * Returns (*SQLiteStorage, cleanup func())

New helpers to add:
- setupLargeBenchDB(b *testing.B) storage.Storage
  * Creates 10K issue database using LargeSQLite fixture
  * Returns configured storage instance

- setupXLargeBenchDB(b *testing.B) storage.Storage
  * Creates 20K issue database using XLargeSQLite fixture
  * Returns configured storage instance

Implementation options:
1. Add to existing compact_bench_test.go (co-located with setupBenchDB)
2. Create new bench_helpers_test.go for organization

Both approaches:
- Build tag: //go:build bench
- Uses fixture generator from internal/testutil/fixtures
- Follows existing setupBenchDB() pattern
- Handles database cleanup

These helpers reduce duplication across new benchmark functions and provide consistent large-scale database setup.


Add test coverage for internal/config package


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).


No logging/debugging for tombstone resurrection events

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


Address gosec security warnings (102 issues)

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


[CRITICAL] Sync validation false positive - legitimate deletions trigger 'data loss detected'

Sync preflight validation incorrectly detects 'data loss' when legitimate deletions occur. This blocks all syncs and is the highest priority fix.


Code review follow-up for bd-dvd and bd-ymj fixes

Track improvements and issues identified during code review of parent resurrection (bd-dvd) and export metadata (bd-ymj) bug fixes.

## Context
Code review identified several areas for improvement:
- Code duplication in metadata updates
- Missing multi-repo support
- Test coverage gaps
- Potential race conditions

## Related Issues
Original bugs fixed: bd-dvd, bd-ymj

## Goals
- Eliminate code duplication
- Add multi-repo support where needed
- Improve test coverage
- Address edge cases


Add tombstone validation: require deleted_at for tombstone status

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

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

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


CLI tests (cli_fast_test.go) are slow and should be integration tests

The TestCLI_* tests in cmd/bd/cli_fast_test.go are taking 4-5 seconds each (40+ seconds total), making them the slowest part of the fast test suite.

Current timings:
- TestCLI_Import: 4.73s
- TestCLI_Blocked: 4.33s
- TestCLI_DepTree: 4.15s
- TestCLI_Close: 3.59s
- TestCLI_DepAdd: 3.50s
- etc.

These tests compile the bd binary once in init(), but then execute it multiple times per test with filesystem operations. Despite being named "fast", they're actually end-to-end CLI integration tests.

Options:
1. Tag with //go:build integration (move to integration suite)
2. Optimize: Use in-memory databases, reduce exec calls, better parallelization
3. Keep as-is but understand they're the baseline for "fast" tests

Total test suite currently: 13.8s (cmd/bd alone is 12.8s, and most of that is these CLI tests)

Fixed by reusing existing bd binary from repo root instead of rebuilding.

Before: 15+ minutes (rebuilding binary for every test package)
After: ~12 seconds (reuses pre-built binary)

The init() function now checks for ../../bd first before falling back to building. This means `go build && go test` is now fast.


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


Add Result.ConvertedToTombstone counter for import statistics

The import Result struct has SkippedDeleted but doesn't distinguish between:
1. Issues skipped because they're in deletions manifest (old behavior)
2. Issues converted from deletions.jsonl to tombstones (new bd-dve behavior)

Add a new ConvertedToTombstone counter to track legacy deletions converted to tombstones during import. This provides better visibility into the migration process.


bd repair-deps - Orphaned dependency cleaner

Find and fix orphaned dependency references.

Implementation:
- Scan all issues for dependencies pointing to non-existent issues
- Report orphaned refs
- Auto-fix with --fix flag
- Interactive mode with --interactive

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


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

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

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

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

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


Modify EnsureIDs to support parent resurrection

Update internal/storage/sqlite/ids.go:189-202 to call TryResurrectParent before failing on missing parent. Add resurrection mode flag, log resurrected parents for transparency. Maintain backwards compatibility with strict validation mode.


Fix Nix flake build test failures

Nix build is failing during test phase with same test errors as Windows.

**Error:**
```
error: Cannot build '/nix/store/rgyi1j44dm6ylrzlg2h3z97axmfq9hzr-beads-0.9.9.drv'.
Reason: builder failed with exit code 1.
FAIL github.com/steveyegge/beads/cmd/bd 16.141s
```

This may be related to test environment setup or the same issues affecting Windows tests.


Implement bd resolve-conflicts (git merge conflicts in JSONL)

Automatically detect and resolve git merge conflicts in .beads/issues.jsonl file.

Features:
- Detect conflict markers in JSONL
- Parse conflicting issues from HEAD and BASE
- Provide mechanical resolution (remap duplicate IDs)
- Support AI-assisted resolution (requires internal/ai package)

See repair_commands.md lines 125-353 for design.


Clean up merge conflict artifacts in .beads directory

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

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

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

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


Add `bd merge` command wrapping 3-way merge logic

Implement CLI command to invoke beads-merge functionality.

**Interface**:
```bash
bd merge <output> <base> <left> <right>
bd merge --debug <output> <base> <left> <right>
```

**Behavior**:
- Exit code 0 on clean merge
- Exit code 1 if conflicts (write conflict markers)
- Support --debug flag for verbose output
- Match beads-merge's existing behavior

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


Fix row iterator resource leak in recursive dependency queries

Critical resource leak in findAllDependentsRecursive() where rows.Close() is called AFTER early return on error, never executing.

Location: internal/storage/sqlite/sqlite.go:1131-1136

Problem:
- rows.Close() placed after return statement
- On scan error, iterator never closed
- Can exhaust SQLite connections under moderate load

Fix: Move defer rows.Close() to execute on all code paths

Impact: Connection exhaustion during dependency traversal


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.


BG's issue to reopen


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

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

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

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


Add fsnotify dependency to go.mod


Add database maintenance commands section to QUICKSTART.md

**Problem:**
Users don't discover `bd compact` or `bd cleanup` commands until their database grows large. These maintenance commands aren't mentioned in quickstart documentation.

Related to issue #349 item #4.

**Current state:**
docs/QUICKSTART.md ends at line 217 with "See README.md for full documentation" but has no mention of maintenance operations.

**Proposed addition:**
Add a "Database Maintenance" section after line 140 (before "Advanced: Agent Mail" section) covering:
- When database grows (many closed issues)
- How to view compaction statistics
- How to compact old issues
- How to delete closed issues
- Warning about permanence

**Example content:**
```markdown
## Database Maintenance

As your project accumulates closed issues, the database grows. Use these commands to manage size:

```bash
# View compaction statistics
bd compact --stats

# Preview compaction candidates (30+ days closed)
bd compact --analyze --json

# Apply agent-generated summary
bd compact --apply --id bd-42 --summary summary.txt

# Immediately delete closed issues (use with caution!)
bd cleanup --force
```

**When to compact:**
- Database file > 10MB with many old closed issues
- After major project milestones
- Before archiving a project phase
```

**Files to modify:**
- docs/QUICKSTART.md (add section after line 140)


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


Add .beads-backup-* pattern to gitignore template

Update the gitignore template in doctor package to include backup directories.

## Change
Add `.beads-backup-*/` to the GitignoreTemplate in `cmd/bd/doctor/gitignore.go`

## Why
Backup directories created by `bd reset --backup` should not be committed to git.
They are local-only recovery tools.

## File
`cmd/bd/doctor/gitignore.go` - look for GitignoreTemplate constant
