Fix linting error in migrate.go

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

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


Add warning when staleness check errors

## Problem

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

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

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

## Current Code

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

## Fix

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

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

## Effort
Easy - 5 minutes


Batch test 1


Add tests for internal/autoimport package

Currently 0.0% coverage. Need tests for auto-import functionality that detects and imports updated JSONL files.


bd doctor --json flag not working

The --json flag on bd doctor command doesn't produce JSON output. It continues to show human-readable output instead. The flag is registered locally on doctorCmd but the code uses the global jsonOutput variable set by PersistentPreRun. Need to investigate why the flag isn't being honored.


Refactor check-health DB access to avoid repeated path resolution

The runCheckHealth lightweight checks (hintsDisabled, checkVersionMismatch, checkSyncBranchQuick) each have duplicated database path resolution logic. Extract a helper function to DRY this up.


Daemon gets stuck when auto-import blocked by git conflicts

CRITICAL: The daemon enters a corrupt state that breaks RPC commands when auto-import is triggered but git pull fails due to uncommitted changes.

Impact: This is a data integrity and usability issue that could cause users to lose trust in Beads. The daemon silently fails for certain commands while appearing healthy.

Reproduction:
1. Make local changes to issues (creates uncommitted .beads/beads.jsonl)
2. Remote has updates (JSONL newer, triggers auto-import)
3. Daemon tries to pull but fails: 'cannot pull with rebase: You have unstaged changes'
4. Daemon enters bad state - 'bd show' and other commands return EOF
5. 'bd list' still works, daemon process is running, no errors logged

Technical details:
- Auto-import check runs in handleRequest() before processing RPC commands
- When import is blocked, it appears to corrupt daemon state
- Likely: deadlock, unclosed transaction, or storage handle corruption
- Panic recovery (server_lifecycle_conn.go:183) didn't catch anything - not a panic

Required fix:
- Auto-import must not block RPC command execution
- Handle git pull failures gracefully without corrupting state
- Consider: skip auto-import if git is dirty, queue import for later, or use separate goroutine
- Add timeout/circuit breaker for import operations
- Log clear warnings when auto-import is skipped

Without this fix, users in collaborative environments will frequently encounter mysterious EOF errors that require daemon restarts.


Add programmatic tip injection API

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


Investigate and upgrade to modernc.org/sqlite 1.39.1+

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

**Issue:** [deleted:bd-47], GH #144

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

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

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

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


Add internal/ai package for AI-assisted repairs

Add AI integration package to support AI-powered repair commands.

Providers:
- Anthropic (Claude)
- OpenAI
- Ollama (local)

Features:
- Conflict resolution analysis
- Duplicate detection via embeddings
- Configuration via env vars (BEADS_AI_PROVIDER, BEADS_AI_API_KEY, etc.)

See repair_commands.md lines 357-425 for design.


Feature P1


Auto-detect issue prefix from existing JSONL in 'bd init'

When running `bd init` in a fresh clone with existing JSONL, it should auto-detect the issue prefix from the JSONL file instead of requiring `--prefix`.

Currently you must specify `--prefix ef` manually. But the JSONL file already contains issues like `ef-1it`, `ef-1jp` etc., so the prefix is known.

**Ideal UX**:
```
$ bd init
Detected issue prefix 'ef' from existing JSONL (38 issues).
✓ Database initialized...
```

This would make fresh clone hydration a single command: `bd init` with no flags.


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)

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.


bd config set succeeds but doesn't persist to config.toml

Commands like `bd config set daemon.auto_push true` return "Set daemon.auto_push = true" but the config file is never created and `bd info --json | jq '.config'` returns null.

**Steps to reproduce:**
1. Run `bd config set daemon.auto_push true`
2. See success message: "Set daemon.auto_push = true"
3. Check `cat .beads/config.toml` → file doesn't exist
4. Check `bd info --json | jq '.config'` → returns null

**Expected:**
- .beads/config.toml should be created with the setting
- bd info should show the config value

**Impact:**
Users can't enable auto-push/auto-commit via CLI as documented in AGENTS.md


Consider backwards compatibility for ready() and list() return type change

PR #481 changed the return types of `ready()` and `list()` from `list[Issue]` to `list[IssueMinimal] | CompactedResult`. This is a breaking change for MCP clients.

## Impact Assessment
Breaking change affects:
- Any MCP client expecting `list[Issue]` from ready()
- Any MCP client expecting `list[Issue]` from list()
- Client code that accesses full Issue fields (description, design, acceptance_criteria, timestamps, dependencies, dependents)

## Current Behavior
- ready() returns `list[IssueMinimal] | CompactedResult`
- list() returns `list[IssueMinimal] | CompactedResult`
- show() still returns full `Issue` (good)

## Considerations
**Pros of current approach:**
- Forces clients to use show() for full details (good for context efficiency)
- Simple mental model (always use show for full data)
- Documentation warns about this

**Cons:**
- Clients expecting list[Issue] will break
- No graceful degradation option
- No migration period

## Potential Solutions
1. Add optional parameter `full_details=false` to ready/list (would increase payload)
2. Create separate tools: ready_minimal/list_minimal + ready_full/list_full
3. Accept breaking change and document upgrade path (current approach)
4. Version the MCP server and document migration guide

## Recommendation
Current approach (solution 3) is reasonable if:
- Changelog clearly documents the breaking change
- Migration guide provided to clients
- Error handling is graceful for clients expecting specific fields


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).


Add --json flags to all bd commands for agent-friendly output


## 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

Migration tool for existing users

Ensure smooth migration for existing users to separate branch workflow.

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

Estimated effort: 2-3 days


PruneDeletions iterates map non-deterministically

## Problem

`PruneDeletions` iterates over `loadResult.Records` which is a map. Go maps iterate in random order, so:

1. `result.PrunedIDs` order is non-deterministic
2. `kept` slice order is non-deterministic → `WriteDeletions` output order varies

## Location
`internal/deletions/deletions.go:213`

## Impact
- Git diffs are noisy (file changes order on each prune)
- Tests could be flaky if they depend on order
- Harder to debug/audit

## Fix
Sort by ID or timestamp before iterating:

```go
// Convert map to slice and sort
var records []DeletionRecord
for _, r := range loadResult.Records {
    records = append(records, r)
}
sort.Slice(records, func(i, j int) bool {
    return records[i].ID < records[j].ID
})
```

GH#518: Document bd setup command

bd setup (e.g. bd setup cursor) is undocumented. Users only find it by grepping source. Need proper docs. See: https://github.com/steveyegge/beads/issues/518


Add --yes flag to bd doctor --fix for non-interactive mode

## Feature Request

Add a `--yes` or `-y` flag to `bd doctor --fix` that automatically confirms all prompts, enabling non-interactive usage in scripts and CI/CD pipelines.

## Current Behavior
`bd doctor --fix` prompts for confirmation before applying fixes, which blocks automated workflows.

## Desired Behavior
`bd doctor --fix --yes` should apply all fixes without prompting.

## Use Cases
- CI/CD pipelines that need to auto-fix issues
- Scripts that automate repository setup
- Pre-commit hooks that want to silently fix issues


Add performance benchmarks for multi-repo hydration

The contributor-workflow-analysis.md asserts sub-second queries (line 702) and describes smart caching via file mtime tracking (Decision #4, lines 584-618), but doesn't provide concrete performance benchmarks.

VC's requirement (from VC feedback section):
- Executor polls GetReadyWork() every 5-10 seconds
- Queries must be sub-second (ideally <100ms)
- Smart caching must avoid re-parsing JSONLs on every query

Suggested performance targets to validate:
- File stat overhead: <1ms per repo
- Hydration (when needed): <500ms for typical JSONL (<25k)
- Query (from cache): <10ms
- Total GetReadyWork(): <100ms (VC's requirement)

Also test at scale:
- N=1 repo (baseline)
- N=3 repos (typical)
- N=10 repos (edge case)

These benchmarks are critical for library consumers like VC that run automated polling loops.


GH#488: Support claude.local.md for local-only config

Allow CLAUDE.local.md for testing bd without committing to repo or overriding shared CLAUDE.md. Not every repo wants committed AI config. See: https://github.com/steveyegge/beads/issues/488


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

Test reservation expiration and renewal

Verify TTL-based reservation expiration works correctly.

Acceptance Criteria:
- Reserve with short TTL (30s)
- Verify other agents can't claim
- Wait for expiration
- Verify reservation auto-released
- Other agent can now claim
- Test renewal/heartbeat mechanism

File: tests/integration/test_reservation_ttl.py

Implemented comprehensive TTL/expiration test suite in tests/integration/test_reservation_ttl.py

Test Coverage:
✅ Short TTL reservations (30s) - verifies TTL is properly set
✅ Reservation blocking - confirms agent2 cannot claim while agent1 holds reservation
✅ Auto-release after expiration - validates expired reservations are auto-cleaned and become available
✅ Renewal/heartbeat - tests that re-reserving extends expiration time

All 4 tests passing in 56.9s total (including 30s+ wait time for expiration tests).

Mock server implements full TTL management:
- Reservation class with expiration tracking
- Auto-cleanup of expired reservations on each request
- Renewal support (same agent re-reserving)
- 409 conflict for cross-agent reservation attempts


Remove duplicate countIssuesInJSONLFile function

init.go and doctor.go both defined countIssuesInJSONLFile. Removed the init.go version which is now unused. The doctor.go version (which calls countJSONLIssues) is the canonical implementation.


Need comprehensive daemon health check command (bd daemon doctor?)


Fix goroutine leak in daemon restart

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

Location: cmd/bd/daemons.go:251

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

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

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

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

Impact: Goroutine leak on every daemon restart

Makefile Integration for Benchmarks

Add a single 'bench' target to the Makefile for running performance benchmarks.

Target:
.PHONY: bench

bench:
	go test -bench=. -benchtime=3s -tags=bench \
		-cpuprofile=cpu.prof -memprofile=mem.prof \
		./internal/storage/sqlite/
	@echo ""
	@echo "Profiles generated. View flamegraph:"
	@echo "  go tool pprof -http=:8080 cpu.prof"

Features:
- Single simple target, no complexity
- Always generates CPU and memory profiles
- Clear output on how to view results
- 3 second benchmark time for reliable results
- Uses bench build tag for heavy benchmarks

Usage:
  make bench                              # Run all benchmarks
  go test -bench=BenchmarkGetReadyWork... # Run specific benchmark


Fixture Generator for Realistic Test Data

Create internal/testutil/fixtures/fixtures.go with functions to generate realistic test data at scale.

Functions:
- LargeSQLite(storage) - 10K issues, native SQLite
- XLargeSQLite(storage) - 20K issues, native SQLite
- LargeFromJSONL(storage) - 10K issues imported from JSONL
- XLargeFromJSONL(storage) - 20K issues imported from JSONL

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

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


Implement `bd prime` command for AI context loading

Create a `bd prime` command that outputs AI-optimized markdown containing essential Beads workflow context. This provides an alternative to the MCP server for token-conscious users and enables context recovery after compaction/clearing.


GH#483: Pre-commit hook should not fail when .beads exists but bd sync fails

Pre-commit hook exit 1 on bd sync --flush-only failure blocks commits even when user removed beads but .beads dir reappears. Should warn not fail. See: https://github.com/steveyegge/beads/issues/483


Add integration tests for multi-repo sync

Test: Clone A deletes issue, Clone B imports Clone A's JSONL. Verify Clone B handles deletion gracefully with resurrection. Test concurrent imports with same orphans (should be idempotent). Test round-trip fidelity (export→delete parent→import→verify structure).


Add transaction helper to replace manual COMMIT/ROLLBACK

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

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


Refactor: deduplicate FindJSONLInDir and FindJSONLPath

## Background

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

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

## Problem

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

## Proposed Solution

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

Need to verify no import cycles would be created.

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


## Problem

bd cleanup deletes closed issues (converting them to tombstones) but does NOT prune expired tombstones. Users expect 'cleanup' to do comprehensive cleanup.

## Current Behavior

1. bd cleanup --force converts closed issues to tombstones
2. Expired tombstones (>30 days) remain in issues.jsonl
3. User must separately run bd compact to prune tombstones
4. bd doctor warns about expired tombstones: Run bd compact to prune

## Expected Behavior

bd cleanup should also prune expired tombstones from issues.jsonl.

## Impact

With v0.30.0 making tombstones the default migration path, this UX gap becomes more visible. Users cleaning up their database should not need to know about a separate bd compact command.

## Proposed Solution

Call pruneExpiredTombstones() at the end of the cleanup command (same function used by compact).

## Files to Modify

- cmd/bd/cleanup.go - Add call to pruneExpiredTombstones after deleteBatch

## Acceptance Criteria

- bd cleanup --force prunes expired tombstones after deleting closed issues
- bd cleanup --dry-run shows what tombstones would be pruned
- JSON output includes tombstone prune results

Configure database connection pool limits for daemon mode

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

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

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

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

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

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

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

Effort: 1 hour


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).


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

# Problem

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

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

# Root Cause Analysis

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

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

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

This happens 279 times!

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

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

# What We've Already Fixed

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

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

# Proposed Solutions

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

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

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

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

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

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

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

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

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

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

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

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

# Recommended Approach

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

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

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

# Current Status

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

# Target

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

# THE REAL ROOT CAUSE (Updated Analysis)

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

## Every Test Creates Its Own Database From Scratch

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

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

**This happens 279 times!**

## These Tests Don't Need Isolation!

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

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

## The Fix: Test Suites with Shared Setup

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

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

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

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

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

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

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

## Why This Works

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

They SHOULD share a database!

## Real Numbers

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

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

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

## Implementation Plan

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

This is way better than shuffling tests into folders!

## Progress Update (2025-11-21)

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

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

## Acceptance Criteria (REALISTIC)

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

## Next Steps

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


UX nightmare: multiple ways daemon can fail with misleading messages


Rapid 5


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

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

**Proposed solutions:**

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

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

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

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

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


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.


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-2752a7a2, bd-9826b69a.

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


Split monolithic sqlite.go into focused files

internal/storage/sqlite/sqlite.go is 1050 lines containing initialization, 20+ CRUD methods, query building, and schema management.

Split into:
- store.go: Store struct & initialization (150 lines)
- bead_queries.go: Bead CRUD (300 lines)
- work_queries.go: Work queries (200 lines)
- stats_queries.go: Statistics (150 lines)
- schema.go: Schema & migrations (150 lines)
- helpers.go: Common utilities (100 lines)

Impact: Impossible to understand at a glance; hard to find specific functionality; high cognitive load

Effort: 6-8 hours


Use -short flag in CI for PR checks

Update CI configuration to use -short flag for PR checks, run full tests nightly.

The slow tests already support testing.Short() and will be skipped.

Expected savings: ~20 seconds for PR checks (fast tests only)

Implementation:
- Update .github/workflows/ci.yml to add -short flag for PR tests
- Create/update nightly workflow for full test runs
- Update README/docs about test strategy

File: .github/workflows/ci.yml:30


Clarify exclusive lock protocol compatibility with multi-repo

The contributor-workflow-analysis.md proposes per-repo file locking (Decision #7) using flock on JSONL files. However, VC (a downstream library consumer) uses an exclusive lock protocol (vc-195, requires Beads v0.17.3+) that allows bd daemon and VC executor to coexist.

Need to clarify:
- Does the proposed per-repo file locking work with VC's existing exclusive lock protocol?
- Do library consumers like VC need to adapt their locking logic?
- Can multiple repos be locked atomically for cross-repo operations?

Context: contributor-workflow-analysis.md lines 662-681


Extract migration functions to migrations.go

Move migrateDirtyIssuesTable, migrateExternalRefColumn, migrateCompositeIndexes, migrateClosedAtConstraint, migrateCompactionColumns, migrateSnapshotsTable, migrateCompactionConfig, migrateCompactedAtCommitColumn, migrateExportHashesTable, migrateContentHashColumn to a separate migrations.go file


TestHooksCheckGitHooks failing - version mismatch (0.23.0 vs 0.23.1)

The test is checking embedded hook versions and expecting 0.23.1, but got 0.23.0. This appears to be a version consistency issue that needs investigation.

Test output:
```
Hook pre-commit version mismatch: got 0.23.0, want 0.23.1
Hook post-merge version mismatch: got 0.23.0, want 0.23.1
Hook pre-push version mismatch: got 0.23.0, want 0.23.1
```

This is blocking the landing of GH #274 fix.


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)


Create architecture decision record (ADR)

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

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

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


Optimize Memory backend GetIssueByExternalRef with index

Currently GetIssueByExternalRef in Memory storage uses O(n) linear search through all issues.

Current code (memory.go:282-308):
for _, issue := range m.issues {
    if issue.ExternalRef != nil && *issue.ExternalRef == externalRef {
        return &issueCopy, nil
    }
}

Proposed optimization:
- Add externalRefToID map[string]string to MemoryStorage
- Maintain it in CreateIssue, UpdateIssue, DeleteIssue
- Achieve O(1) lookup like SQLite's index

Impact: Low (--no-db mode typically has smaller datasets)

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)


Create Docker image for Agent Mail

Containerize Agent Mail server for easy deployment.

Acceptance Criteria:
- Dockerfile with Python 3.14
- Health check endpoint
- Volume mount for storage
- Environment variable configuration
- Multi-arch builds (amd64, arm64)

File: deployment/agent-mail/Dockerfile


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

## Problem

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

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

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

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

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

## Fix
Escape regex special characters:

```go
import "regexp"

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


Add simple cleanup command to delete closed issues

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


Implement bd migrate command

Add bd migrate command to move issues between repos with filtering. Should support: filtering by status/priority/labels, dry-run mode, preserving dependencies, handling source_repo field updates.


Integration test: mutation to export latency

Measure time from bd create to JSONL update. Verify <500ms latency. Test with multiple rapid mutations to verify batching.


Review and document rarely-used commands

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

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

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

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

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


Feature with design

This is a description


Audit Current Cache Usage

Understand exactly what code depends on the storage cache

Audit complete. See CACHE_AUDIT.md for full findings.

Summary:
- Cache was already removed in commit 322ab63 (2025-10-28)
- server_cache_storage.go deleted (~286 lines)
- All getStorageForRequest calls replaced with s.storage
- All environment variables removed
- MCP multi-repo works via per-project daemon architecture
- All tests updated and passing
- Only stale comment in server.go needed fixing


Add topological sort utility functions

Create internal/importer/sort.go with utilities for depth-based sorting of issues. Functions: GetHierarchyDepth(id), SortByDepth(issues), GroupByDepth(issues). Include stable sorting for same-depth issues.


Update LINTING.md with current baseline

After cleanup, document the remaining acceptable baseline in LINTING.md so we can track regression.


Unit tests for FileWatcher

Test watcher detects JSONL changes. Test git ref changes trigger import. Test debounce integration. Test watcher recovery from file removal/rename.


Default to YES for git hooks and merge driver installation

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


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


Isolate RPC server startup into rpc_server.go

Create internal/daemonrunner/rpc_server.go with StartRPC function. Move startRPCServer logic here and return typed handle.


Deletion propagation via deletions manifest

## Problem

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

## Root Cause

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

## Solution: Deletions Manifest

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

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

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

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

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

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

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

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

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

Create examples for common workflows

Add examples/ subdirectories: OSS contributor workflow, team branch workflow, multi-phase development, multiple personas (architect/implementer). Each with README and sample configs.


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.


Improve test coverage for cmd/bd/setup (28.4% → 50%)

The setup package has only 28.4% test coverage. Setup commands are critical for first-time user experience.

Current coverage: 28.4%
Target coverage: 50%


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.

Centralize error handling patterns in storage layer

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

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

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

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

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

Effort: 5-7 hours


Fix inconsistent error handling in multi-repo deletion tracking

From bd-xo6b code review: Multi-repo deletion tracking has mixed failure modes that can leave system in inconsistent state.

**Current behavior (daemon_sync.go):**
- Snapshot capture (L505-514): Hard fail → aborts sync
- Merge/prune (L575-584): Hard fail → aborts sync
- Base snapshot update (L613-619): Soft fail → logs warning, continues

**Critical problem:**
If merge fails on repo 3 of 5:
- Repos 1-2 have already merged and deleted issues (irreversible)
- Repos 3-5 are untouched
- Database is in partially-updated state
- No rollback mechanism

**Real-world scenario:**
```
Sync with repos [A, B, C]:
1. Capture snapshots A ✓, B ✓, C ✗ → ABORT (good)
2. Merge A ✓, B ✗ → ABORT but A already deleted issues (BAD - no rollback)
3. Update base A ⚠, B ⚠ → Warnings only (inconsistent with 1 & 2)
```

**Solution options:**
1. **Two-phase commit:**
   - Phase 1: Validate all repos (check files exist, readable, parseable)
   - Phase 2: Apply changes atomically (or fail entirely before any mutations)

2. **Fail-fast validation:**
   - Before any snapshot/merge operations, validate all repos upfront
   - Abort entire sync if any repo fails validation

3. **Make base snapshot update consistent:**
   - Either make it hard-fail like the others, or make all soft-fail

**Files:**

- cmd/bd/daemon_sync.go:575-584 (merge/prune)
- cmd/bd/daemon_sync.go:613-619 (base snapshot update)

**Recommendation:** Use option 1 (two-phase) or option 2 (fail-fast validation) + fix base snapshot inconsistency.

Released by executor after budget limit hit. Tests were already fixed manually. Issue can be closed when tests are verified to pass.


Pre-sync integrity check (bd sync --check)

Add bd sync --check flag that detects problematic states before attempting sync: forced pushes on sync branch (via git reflog), prefix mismatches in JSONL, orphaned children with missing parents. Output combined diagnostic without modifying state.


Propagate context through command handlers

Thread context from signal-aware parent through all command handlers.

## Context
Part of context propagation work. Builds on bd-rtp (signal-aware contexts).

## Current State
Many command handlers create their own context.Background() locally instead of receiving context from parent.

## Implementation
1. Add context parameter to command handler functions
2. Pass context from cobra command Run/RunE closures
3. Update all storage operations to use propagated context

## Example Pattern
```go
// Before
Run: func(cmd *cobra.Command, args []string) {
    ctx := context.Background()
    store.GetIssues(ctx, ...)
}

// After
Run: func(cmd *cobra.Command, args []string) {
    // ctx comes from parent signal-aware context
    store.GetIssues(ctx, ...)
}
```

## Files to Update
- All cmd/bd/*.go command handlers
- Ensure context flows from main -> cobra -> handlers -> storage

## Benefits
- Commands respect cancellation signals
- Consistent context handling
- Enables timeouts and deadlines

## Acceptance Criteria
- [ ] All command handlers use propagated context
- [ ] No new context.Background() calls in command handlers
- [ ] Context flows from signal handler to storage layer


Implement content-hash based collision resolution for deterministic convergence

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

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

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

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


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


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


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

Pre-push hook and daemon export produce different JSONL

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

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

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

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

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

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

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


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

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

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

**Proposed behavior:**
- `bd sync --squash` accumulates pending exports
- Only commits when explicitly requested or on session end
- Default behavior unchanged (immediate commits for orchestration)

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

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


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


bd sync false positive: conflict detection triggers on JSON-encoded angle brackets in issue content

The bd sync --import-only command incorrectly detects conflict markers when issue descriptions contain the text '<<<<<<<' or '>>>>>>>' as legitimate content (e.g., documentation about git conflict markers).

**Reproduction:**
1. Create issue with design field containing: 'Read file, extract <<<<<<< / ======= / >>>>>>> markers'
2. Export to JSONL (gets JSON-encoded as \u003c\u003c\u003c...)
3. Commit and push
4. Pull from remote
5. bd sync --import-only fails with: 'Git conflict markers detected in JSONL file'

**Root cause:**
The conflict detection appears to decode JSON before checking for conflict markers, causing false positives when issue content legitimately contains these strings.

**Expected behavior:**
Conflict detection should only trigger on actual git conflict markers (literal '<<<<<<<' bytes in the raw file), not on JSON-encoded content within issue fields.

**Test case:**
VC project at ~/src/dave/vc has vc-85 'JSONL Conflict Parser' which documents conflict parsing and triggers this bug.

**Suggested fixes:**
1. Only scan for literal '<<<<<<<' bytes (not decoded JSON content)
2. Parse JSONL first and only flag unparseable lines
3. Check git merge state (git status) to confirm actual conflict
4. Add --skip-conflict-check flag for override


bd info whats-new missing releases

Current release is v0.25.1 but `bd info --whats-new` stops at v0.23.0, indicating something is missing in the create new release workflow.

Extract batch operations to batch_ops.go

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


Add docs/architecture/event_driven.md

Copy event_driven_daemon.md into docs/ folder. Add to documentation index.


Audit and standardize JSON output across all commands

Ensure consistent JSON format and error handling when --json flag is used.

**Scope:**
1. Verify all commands respect --json flag
2. Standardize success response format
3. Standardize error response format
4. Document JSON schemas

**Commands to audit:**
- Core CRUD: create, update, delete, show, list, search ✓
- Queries: ready, blocked, stale, count, stats, status
- Deps: dep add/remove/tree/cycles
- Labels: label commands
- Comments: comments add/list/delete
- Epics: epic status/close-eligible
- Export/import: already support --json ✓

**Testing:**
- Success cases return valid JSON
- Error cases return valid JSON (not plain text)
- Consistent field naming (snake_case vs camelCase)
- Array vs object wrapping consistency


Issue 1


Support Ubuntu 20.04 LTS (glibc compatibility issue)

Starting at v0.22, precompiled binaries require GLIBC 2.32+ which is not available on Ubuntu 20.04 LTS (Focal Fossa). Ubuntu 20.04 has GLIBC 2.31.

Error:
```
bd: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by bd)
bd: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by bd)
```

Current workarounds:
1. Upgrade to Ubuntu 22.04+
2. Build from source: `go build -o bd ./cmd/bd/`

Root cause: Go 1.24+ runtime requires newer glibc. CGO is already disabled in .goreleaser.yml.

Possible solutions:
- Pin Go version to 1.21 or 1.22 for releases
- Use Docker/cross-compile with older build environment
- Provide separate build for older distros
- Document minimum requirements clearly

Decision: Document minimum requirements in README instead of pinning Go version.

Rationale:
- Ubuntu 20.04 LTS standard support ended April 2025 (already EOL)
- Pinning Go prevents security fixes, performance improvements, and new features
- Users on EOL distros can upgrade OS or build from source
- Added Requirements section to README with clear glibc 2.32+ requirement


Wire config to import pipeline

Connect import.orphan_handling config to importer.go and sqlite validation functions. Pass mode flag through call chain. Implement all four modes (strict/resurrect/skip/allow) with proper error messages and logging.


Add optional post-merge git hook example for bd sync

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

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

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

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


[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.


Support --parent flag in daemon mode

Added support for hierarchical child issue creation using --parent flag in daemon mode. Previously only worked in direct mode.


Update python-agent example with Agent Mail integration

Modify examples/python-agent/agent.py to use Agent Mail adapter at 4 integration points.

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


Daemon crashes silently when multiple .db files exist in .beads/

When daemon detects multiple .db files (after filtering out .backup and vc.db files), it writes error details to .beads/daemon-error file before exiting.

The error file is checked when:
1. Daemon discovery fails to connect (internal/daemon/discovery.go)
2. Auto-start fails to yield a running daemon (cmd/bd/main.go)
3. Daemon list shows 'daemon not responding' error

This makes the error immediately visible to users without requiring them to check daemon logs.

File created:  cmd/bd/daemon.go (writes daemon-error on multiple .db detection)
Files modified:
- internal/daemon/discovery.go (reads daemon-error and surfaces in DaemonInfo.Error)
- cmd/bd/main.go (displays daemon-error when auto-start fails)

Testing: Create multiple .db files in .beads/, start daemon, verify error file created and shown in bd daemons list

Root cause: Daemon exits with os.Exit(1) when multiple .db files detected (daemon.go:1381), but error only goes to daemon log file. User sees 'daemon not responding' without knowing why.

Current detection:
- daemon.go filters out .backup and vc.db files
- bd doctor detects multiple databases
- Error message tells user to run 'bd init' or manually remove

Problem: Error is not user-visible unless they check daemon logs.

Proposed fix options:
1. Surface the error in 'bd info' and 'bd daemons list' output
2. Add a hint in error messages to run 'bd doctor' when daemon fails
3. Make daemon write error to a .beads/daemon-error file that gets checked
4. Improve 'bd doctor' to run automatically when daemon is unhealthy


Audit and consolidate collision test coverage

The codebase has 2,019 LOC of collision detection tests across 3 files. Run coverage analysis to identify redundant test cases and consolidate.

Test files:
- `cmd/bd/import_collision_test.go` - 974 LOC
- `cmd/bd/autoimport_collision_test.go` - 750 LOC
- `cmd/bd/import_collision_regression_test.go` - 295 LOC

Total: 2,019 LOC of collision tests

Analysis steps:
1. Run coverage analysis
2. Identify redundant tests
3. Document findings

Consolidation strategy:
- Keep regression tests for critical bugs
- Merge overlapping table-driven tests
- Remove redundant edge case tests covered elsewhere
- Ensure all collision scenarios still tested

Expected outcome: Reduce to ~1,200 LOC (save ~800 lines) while maintaining coverage

Impact: Faster test runs, easier maintenance, clearer test intent


Update documentation for hash IDs and aliases

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

## Files to Update

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Hash IDs are generated deterministically:

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

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

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

## Alias Conflict Resolution

When multiple clones assign same alias to different issues:

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

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

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

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

## Migration Steps

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

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

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

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

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

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

## FAQ

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

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

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

### 6. CHANGELOG.md
```markdown
## v2.0.0 (YYYY-MM-DD)

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

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

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

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

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

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


Add tests for performFlush error handling in FlushManager

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

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

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

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

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

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


Add test case for symmetric collision (both clones create same ID simultaneously)

TestTwoCloneCollision demonstrates the problem, but we need a simpler unit test for the collision resolver itself.

Test should verify:
- Two issues with same ID, different content
- Content hash determines winner deterministically
- Result is same regardless of which clone imports first
- No title swapping occurs

This can be a simpler test than the full integration test.


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%


GH#520: Daemon sync-branch commit fails with pre-commit hooks (needs --no-verify)

gitCommitInWorktree in daemon_sync_branch.go missing --no-verify flag, causing commit failures when pre-commit hooks installed. Library function in worktree.go:684 has correct impl. See: https://github.com/steveyegge/beads/issues/520


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)


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.

## Implementation Progress

**Completed:**
1. ✅ Mutation events infrastructure (bd-143 equivalent)
   - MutationEvent channel in RPC server
   - Events emitted for all write operations: create, update, close, label add/remove, dep add/remove, comment add
   - Non-blocking emission with dropped event counter

2. ✅ FileWatcher with fsnotify (bd-b0c7f7ef related)
   - Watches .beads/issues.jsonl and .git/refs/heads
   - 500ms debounce
   - Polling fallback if fsnotify unavailable

3. ✅ Debouncer (bd-144 equivalent)
   - 500ms debounce for both export and import triggers
   - Thread-safe trigger/cancel

4. ✅ Separate export-only and import-only functions
   - createExportFunc(): exports + optional commit/push (no pull/import)
   - createAutoImportFunc(): pull + import (no export)
   - Target latency <500ms achieved by avoiding full sync

5. ✅ Dropped events safety net (bd-eef03e0a related)
   - Atomic counter tracks dropped mutation events
   - 60-second health check triggers export if events were dropped
   - Prevents silent data loss from event storms

**Still Needed:**
- Platform-specific tests (bd-69bce74a)
- Integration test for mutation→export latency (bd-140)
- Unit tests for FileWatcher (bd-b0c7f7ef)
- Unit tests for Debouncer (bd-144)
- Event storm stress test (bd-eef03e0a)
- Documentation update (bd-142)

**Next Steps:**
Add comprehensive test coverage before enabling events mode by default.


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.

Assigned issue


Improve clean vs cleanup command naming/documentation

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

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

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

2. Keep names but improve help text and documentation

3. Add prominent warnings in help output

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

**Files to modify:**
- cmd/bd/clean.go
- cmd/bd/cleanup.go

Investigate jujutsu VCS as potential solution for conflict-free merging

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

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

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

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

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

Add guidance for self-hosting projects

The contributor-workflow-analysis.md is optimized for OSS contributors making PRs to upstream projects. However, it doesn't address projects like VC that use beads for their own development (self-hosting).

Self-hosting projects differ from OSS contributors:
- No upstream/downstream distinction (they ARE the project)
- May run automated executors (not just humans)
- In bootstrap/early phase (stability matters)
- Single team/owner (not multiple contributors with permissions)

Guidance needed on:
- When self-hosting projects should stay single-repo (default, recommended)
- When they should adopt multi-repo (team planning, multi-phase dev)
- How automated executors should handle multi-repo (if at all)
- Special considerations for projects in bootstrap phase

Examples of self-hosting projects: VC (building itself with beads), internal tools, pet projects


Log errors from timer-triggered flushes instead of discarding


User Diagnostics (bd doctor --perf)

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

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

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

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

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

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


RPC diagnostics: BD_RPC_DEBUG timing logs

Add lightweight diagnostic logging for RPC connection attempts:
- BD_RPC_DEBUG=1 prints to stderr:
  - Socket path being dialed
  - Socket exists check result
  - Dial start/stop time
  - Connection outcome
- Improve bd daemon --status messaging when lock not held

This helps field triage of connection issues without verbose daemon logs.

bd-hv01: Race condition with concurrent snapshot operations

## Problem
Snapshot files have no locking. Multiple processes can call captureLeftSnapshot simultaneously:

1. Process A: export → begins snapshot
2. Process B: export → begins snapshot
3. Process A: writes partial left.jsonl
4. Process B: overwrites with its left.jsonl
5. Process A: completes merge with wrong snapshot

## Impact
- Data corruption in multi-process scenarios
- Daemon + manual sync race
- Multiple git clones on same filesystem

## Fix
Use atomic file operations with process-specific temp files:
```go
func captureLeftSnapshot(jsonlPath string) error {
    _, leftPath := getSnapshotPaths(jsonlPath)
    tempPath := fmt.Sprintf("%s.%d.tmp", leftPath, os.Getpid())
    if err := copyFileSnapshot(jsonlPath, tempPath); err != nil {
        return err
    }
    return os.Rename(tempPath, leftPath) // Atomic on POSIX
}
```

## Files Affected
- cmd/bd/deletion_tracking.go:24-29 (captureLeftSnapshot)
- cmd/bd/deletion_tracking.go:31-36 (updateBaseSnapshot)


Sync protection mechanism resurrects deleted issues

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

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

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

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

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

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

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


Sync should cleanup snapshot files after completion

After sync completion, orphan .base.jsonl and .left.jsonl snapshot files remain in .beads/ directory. These should be cleaned up on successful sync.


VCS-agnostic sync support

Make bd sync work with multiple VCS types (git, jujutsu, mercurial, sapling) by detecting VCS per repo and using appropriate sync commands, supporting mixed-VCS multi-repo configs.


bd message: Add input validation for --importance flag

The --importance flag accepts any string without validation, leading to confusing server errors.

**Location:** cmd/bd/message.go:256-258

**Fix:**
- Add flag validation for: low, normal, high, urgent
- Add shell completion support
- Validate in runMessageSend before sending

**Impact:** Better UX, prevents confusing errors


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.

Update agent workflow section to include Agent Mail coordination as optional step.

Acceptance Criteria:
- Add Agent Mail to recommended workflow
- Show both with/without examples
- Update "Multi-Agent Patterns" section
- Cross-reference to AGENT_MAIL.md

File: AGENTS.md (lines 468-475)

Add integration tests for CompactedResult in MCP server

The CompactedResult model is used for list operations when results exceed COMPACTION_THRESHOLD (20 items), but there are no integration tests verifying the actual MCP server behavior with large result sets.

## What's Missing
- Integration test that mocks a large result set (>20 issues) and verifies CompactedResult is returned
- Verification that preview_count matches PREVIEW_COUNT (5)
- Verification that total_count reflects actual result size
- Test that compaction threshold is configurable (currently hardcoded COMPACTION_THRESHOLD=20)

## Why This Matters
The compaction logic is critical for preventing context overflow with large lists. Without integration tests, we can't verify it works correctly with the actual MCP protocol.

## Suggested Implementation
Create test_mcp_compaction.py with:
1. test_list_with_large_result_set_returns_compacted_result()
2. test_ready_work_respects_compaction_threshold()
3. test_compacted_result_structure_is_valid()

Duplicate DefaultRetentionDays constants

## Problem

There are now two constants for the same value:

1. `deletions.DefaultRetentionDays = 7` in `internal/deletions/deletions.go:184`
2. `configfile.DefaultDeletionsRetentionDays = 7` in `internal/configfile/configfile.go:102`

## Impact
- DRY violation
- Risk of values getting out of sync
- Confusing which one to use

## Fix
Remove the constant from `deletions` package and have it import from `configfile`, or create a shared constants package.


Investigate database pollution - issue count anomalies

Multiple repos showing inflated issue counts suggesting cross-repo pollution:
- ~/src/dave/beads: 895 issues (675 open) - clearly polluted
- ~/src/stevey/src/beads: 280 issues (expected ~209-220) - possibly polluted

Need to investigate:
1. Source of pollution (multi-repo sync issues?)
2. How many duplicate/foreign issues exist
3. Whether recent sync operations caused cross-contamination
4. How to clean up and prevent future pollution

Investigation findings:

**Root cause identified:**
- NOT cross-repo contamination
- NOT automated test leakage (tests properly use t.TempDir())
- Manual testing during template feature development (Nov 2-4)
- Commit ba325a2: "test issues were accidentally committed during template feature development"

**Database growth timeline:**
- Nov 3: 19 issues (baseline)
- Nov 2-5: +244 issues (massive development spike)
- Nov 6-7: +40 issues (continued growth)
- Current: 291 issues → 270 after cleanup

**Test pollution breakdown:**
- 21 issues matching "Test " prefix pattern
- Most created Nov 2-5 during feature development
- Pollution from manual `./bd create "Test issue"` commands in production workspace
- All automated tests properly isolated with t.TempDir()

**Cleanup completed:**
- Ran scripts/cleanup-test-pollution.sh successfully
- Removed 21 test issues
- Database reduced from 291 → 270 issues (7.2% cleanup)
- JSONL synced to git

**Prevention strategy:**
- Filed follow-up issue for prevention mechanisms
- Script can be deleted once prevention is in place
- Tests are already properly isolated - no code changes needed there


Add bd hooks install command to embed git hooks in binary

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

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

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

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


Update AGENTS.md and README.md with "bd daemons" documentation

Document the new "bd daemons" command and all subcommands in AGENTS.md and README.md. Include examples and troubleshooting guidance.

Extract daemon server functions to daemon_server.go


Update JSONL format to use hash IDs

Update JSONL import/export to use hash IDs, store aliases separately.

## Current JSONL Format
```jsonl
{"id":"bd-1c63eb84","title":"Fix bug","status":"open",...}
{"id":"bd-9063acda","title":"Add test","status":"open",...}
```

## New JSONL Format (Option A: Include Alias)
```jsonl
{"id":"bd-af78e9a2","alias":1,"title":"Fix bug","status":"open",...}
{"id":"bd-e5f6a7b8","alias":2,"title":"Add test","status":"open",...}
```

## New JSONL Format (Option B: Hash ID Only)
```jsonl
{"id":"bd-af78e9a2","title":"Fix bug","status":"open",...}
{"id":"bd-e5f6a7b8","title":"Add test","status":"open",...}
```

Store aliases in separate .beads/aliases.jsonl (local only, git-ignored):
```jsonl
{"hash":"bd-af78e9a2","alias":1}
{"hash":"bd-e5f6a7b8","alias":2}
```

**Recommendation**: Option B (hash only in main JSONL)
- Cleaner git diffs (no alias conflicts)
- Aliases are workspace-local preference
- Main JSONL is canonical, portable

## Export Changes
File: cmd/bd/export.go
```go
// Export issues with hash IDs
for _, issue := range issues {
    json := marshalIssue(issue)  // Uses issue.ID (hash)
    // Don't include alias in JSONL
}

// Separately export aliases to .beads/aliases.jsonl
exportAliases(issues)
```

## Import Changes
File: cmd/bd/import.go, internal/importer/importer.go
```go
// Import issues by hash ID
issue := unmarshalIssue(line)
// Assign new alias on import (don't use incoming alias)
issue.Alias = getNextAlias()

// No collision detection needed! Hash IDs are globally unique
```

## Dependency Reference Format
No change needed - already uses issue IDs:
```json
{"depends_on_id":"bd-af78e9a2","type":"blocks"}
```

## Files to Modify
- cmd/bd/export.go (use hash IDs)
- cmd/bd/import.go (import hash IDs, assign aliases)
- internal/importer/importer.go (remove collision detection!)
- .gitignore (add .beads/aliases.jsonl)

## Testing
- Test export produces hash IDs
- Test import assigns new aliases
- Test dependencies preserved with hash IDs
- Test no collision detection triggered


Add 'new' as alias for 'create' command


Prefix detection treats embedded hyphens as prefix delimiters

The prefix detection logic in bd import incorrectly identifies issues like 'vc-baseline-test' and 'vc-92cl-gate-test' as having different prefixes ('vc-baseline-' and 'vc-92cl-gate-') instead of recognizing them as having the standard 'vc-' prefix with hyphenated suffixes.

This breaks import with error: 'prefix mismatch detected: database uses vc- but found issues with prefixes: [vc-92cl-gate- (1 issues) vc-baseline- (1 issues)]'

The prefix should be determined by the pattern: prefix is everything up to and including the first hyphen. The suffix can contain hyphens without being treated as part of the prefix.

Example problematic IDs:
- vc-baseline-test (detected as prefix: vc-baseline-)
- vc-92cl-gate-test (detected as prefix: vc-92cl-gate-)
- vc-test (correctly detected as prefix: vc-)

Impact: Users cannot use descriptive multi-part IDs without triggering false prefix mismatch errors.


Frontend task


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

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


Add ON DELETE CASCADE to child_counters schema

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