Testing & Validation

Ensure reliability through comprehensive testing.

Completed comprehensive Agent Mail test coverage analysis and implementation.

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

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

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

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

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

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


Add tests for Integration Layer Implementation

While implementing bd-wfmw, noticed missing tests

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


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))
```


Document error handling strategy for metadata update failures

Multiple places silently ignore metadata update failures (sync.go:614-617, import.go:320-322) with non-fatal warnings. This is intentional (degrades gracefully to mtime-based approach) but not well documented.

Add comments explaining:
- Why these failures are non-fatal
- How system degrades gracefully
- What the fallback behavior is (mtime-based detection)


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

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

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


Review multi-repo deletion tracking implementation

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

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

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

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

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

Key findings:

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

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

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

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

Detailed review notes available in conversation history.


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

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


Enhance dep tree to show full dependency graph

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

## Current Behavior

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

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

This doesn't show any of the dependency structure.

## Desired Behavior

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

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

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

## Suggested Options

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

## Use Case

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


bd ready includes blocked issues (GH#544)

Issues with 'blocks' dependencies still appear in bd ready. The ready query should exclude issues that have unresolved blockers.

Fix in: cmd/bd/ready.go or internal query logic.


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).


Add t.Parallel() to slow hash multiclone tests

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

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

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

File: beads_hash_multiclone_test.go:34, :101


Add integration tests for adapter library

Test suite for beads_mail_adapter.py covering all scenarios.

Acceptance Criteria:
- Test enabled mode (server available)
- Test disabled mode (server unavailable)
- Test graceful degradation (server dies mid-operation)
- Test reservation conflicts
- Test message sending/receiving
- Mock HTTP server for testing
- 90%+ code coverage

File: lib/test_beads_mail_adapter.py

Test suite completed with 29 comprehensive tests covering:
- Enabled mode (server available): 10 tests
- Disabled mode (server unavailable): 2 tests
- Graceful degradation: 4 tests
- Reservation conflicts: 2 tests
- Configuration: 5 tests
- Health check scenarios: 3 tests
- HTTP error handling: 3 tests

**Performance**: All tests run in 10ms (fast!)

**Coverage highlights**:
✅ Server health checks (ok, degraded, error, timeout)
✅ All API operations (reserve, release, notify, check_inbox, get_reservations)
✅ HTTP errors (404, 409 conflict, 500, 503)
✅ Network errors (timeout, connection refused)
✅ Malformed responses (bad JSON, empty body, plain text errors)
✅ Environment variable configuration
✅ Graceful degradation when server dies mid-operation
✅ Conflict handling with both JSON and plain text errors
✅ Dict wrapper responses ({"messages": [...]} and {"reservations": [...]})
✅ Custom TTL for reservations
✅ Default agent name fallback

No external dependencies, no slow integration tests, just fast unit tests with mocks.


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

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

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

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

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

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

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


Add alias field to database schema

Extend database schema to support human-friendly aliases alongside hash IDs.

## Database Changes

### 1. Add alias column to issues table
```sql
ALTER TABLE issues ADD COLUMN alias INTEGER UNIQUE;
CREATE INDEX idx_issues_alias ON issues(alias);
```

### 2. Add alias counter table
```sql
CREATE TABLE alias_counter (
    id INTEGER PRIMARY KEY CHECK (id = 1),
    next_alias INTEGER NOT NULL DEFAULT 1
);
INSERT INTO alias_counter (id, next_alias) VALUES (1, 1);
```

### 3. Add alias conflict tracking (for multi-clone scenarios)
```sql
CREATE TABLE alias_history (
    issue_id TEXT NOT NULL,
    alias INTEGER NOT NULL,
    assigned_at TIMESTAMP NOT NULL,
    workspace_id TEXT NOT NULL,
    PRIMARY KEY (issue_id, alias)
);
```

## API Changes

### CreateIssue
- Generate hash ID
- Assign next available alias
- Store both in database

### ResolveAliasConflicts (new function)
- Detect conflicting alias assignments after import
- Apply resolution strategy (content-hash ordering)
- Reassign losers to next available aliases

## Migration Path
```bash
bd migrate --add-aliases  # Adds columns, assigns aliases to existing issues
```

## Files to Modify
- internal/storage/sqlite/schema.go
- internal/storage/sqlite/sqlite.go (CreateIssue, GetIssue)
- internal/storage/sqlite/aliases.go (new file for alias logic)
- internal/storage/sqlite/migrations.go

## Testing
- Test alias auto-assignment on create
- Test alias uniqueness constraint
- Test alias lookup performance
- Test alias conflict resolution


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


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)


Issue 1


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

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

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

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

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


bd validate - Comprehensive health check

Run all validation checks in one command.

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

Supports --fix-all for auto-repair.

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

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


Add --parent flag to bd onboard output

bd onboard didn't document --parent flag for epic subtasks, causing AI agents to guess wrong syntax. Added --parent example and CLI help section pointing to bd <cmd> --help.

Fixes: https://github.com/steveyegge/beads/issues/402


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


Add fallback to polling on watcher failure

Detect fsnotify.NewWatcher() errors and log warning. Auto-switch to polling mode with 5s ticker. Add BEADS_WATCHER_FALLBACK env var to control behavior.


bd resolve-conflicts - Git merge conflict resolver

Automatically resolve JSONL merge conflicts.

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

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

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


Add fsnotify dependency to go.mod


Improve sync branch divergence recovery UX

When the sync branch diverges significantly from remote (e.g., 89 local vs 36 remote commits), bd sync fails with a confusing rebase conflict error.

**Current behavior:**
```
Error committing to sync branch: failed to push from worktree: push failed and recovery rebase also failed
error: could not apply 8712f35... bd sync: 2025-12-13 07:30:04
CONFLICT (content): Merge conflict in .beads/issues.jsonl
```

User is left in a broken state with no clear recovery path.

**Expected behavior:**
1. Detect significant divergence before attempting sync
2. Offer options: 'Sync branch diverged. Choose: (1) Reset to remote (2) Force push local (3) Manual merge'
3. Provide clear recovery commands if automatic recovery fails

**Context:** This happened after multiple clones synced different states. The workaround was manually resetting the sync branch worktree to remote.


Doctor: exclude merge artifacts from 'multiple JSONL' warning

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

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

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

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

## Files
- cmd/bd/doctor/ (JSONL check logic)


Daemon fails to auto-import after git pull updates JSONL

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

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

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

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

See WYVERN_SYNC_ISSUE.md for full analysis.

**Fixed in v0.21.2!**

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

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

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


Document CompactedResult response format in CONTEXT_ENGINEERING.md

The CompactedResult is a new response format that MCP clients need to understand, but it's not documented in CONTEXT_ENGINEERING.md.

## What's Missing
- Example CompactedResult JSON response
- How to detect if a result is compacted
- How to request full results (disable compaction or increase limit)
- Guidance on handling both list[IssueMinimal] and CompactedResult return types
- Migration guide for clients expecting list[Issue] from ready() and list()

## Documentation Gaps
Currently CONTEXT_ENGINEERING.md explains the optimization strategy but doesn't show:
1. Sample CompactedResult response
2. Client-side code examples for handling compaction
3. When compaction is triggered (>20 results)
4. How to get all results if needed

## Suggested Additions
Add new section \"Handling Large Result Sets\" with:
- CompactedResult schema documentation
- Python client example for handling both response types
- Guidance on re-issuing queries with better filters

Reduce sync rounds in multiclone tests

Analyze and reduce the number of sync rounds in hash multiclone tests.

Current state:
- TestHashIDs_MultiCloneConverge: 1 round of syncs across 3 clones
- TestHashIDs_IdenticalContentDedup: 2 rounds across 2 clones

Investigation needed:
- Profile to see how much time each sync takes
- Determine minimum rounds needed for convergence
- Consider making rounds configurable via env var

WASM port of bd for Claude Code Web sandboxes

Enable beads to work in Claude Code Web sandboxes by compiling bd to WebAssembly.

## Problem
Claude Code Web sandboxes cannot install bd CLI due to network restrictions:
- GitHub releases return 403
- go install fails with DNS errors
- Binary cannot be downloaded

## Solution
Compile bd Go codebase to WASM, publish to npm as drop-in replacement.

## Technical Approach
- Use GOOS=js GOARCH=wasm to compile bd
- modernc.org/sqlite already supports js/wasm target
- Publish to npm as bd-wasm package
- Full feature parity with bd CLI

## Success Criteria
- bd-wasm installs via npm in web sandbox
- All core bd commands work identically
- JSONL output matches native bd
- Performance within 2x of native

WASM port abandoned - Claude Code Web has full VMs not browser restrictions. Better: npm + native binary


worktree: any bd command is slow

in a git worktree any bd command is slow, with a 2-3s pause before any results are shown. The identical command with `--no-daemon` is near instant.

GH#517: Fix Claude setting wrong priority syntax on new install

Claude uses 'medium' instead of P2/2 for priority, causing infinite error loops. bd prime hook or docs not clear enough. See: https://github.com/steveyegge/beads/issues/517


Add commit and branch to bd version output

The 'bd version' command reports commit and branch correctly when built with 'go build' (thanks to Go 1.25+ automatic VCS info embedding), but NOT when installed with 'go install' or 'make install'. Need to either: 1) Update Makefile to use 'go build' instead of 'go install', or 2) Add explicit ldflags to both Makefile and .goreleaser.yml to ensure commit/branch are always set regardless of build method.


Use stable repo identifiers instead of full paths in metadata keys

## Problem
bd-ar2.2 uses full absolute paths as metadata key suffixes:
```go
updateExportMetadata(exportCtx, store, path, log, path)
// Creates: last_import_hash:/Users/stevey/src/cino/beads/repo1/.beads/issues.jsonl
```

## Issues
1. Absolute paths differ across machines/clones
2. Keys are very long
3. If user moves repo or clones to different path, metadata becomes orphaned
4. Metadata won't be portable across team members

## Better Approach
Use source_repo identifiers from multi-repo config (e.g., ".", "../frontend"):
```go
// Get mapping of jsonl_path -> source_repo identifier
for _, path := range multiRepoPaths {
    repoKey := getRepoKeyForPath(path)  // e.g., ".", "../frontend"
    updateExportMetadata(exportCtx, store, path, log, repoKey)
}
```

This creates stable keys like:
- `last_import_hash:.`
- `last_import_hash:../frontend`

## Related
Depends on bd-ar2.10 (hasJSONLChanged update)


Refactor sqlite.go into focused modules

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


Testing event-driven mode!


Add merge helper commands (bd sync --merge)

Add commands to merge beads branch back to main.

Tasks:
- Implement bd sync --merge command
- Implement bd sync --status command
- Implement bd sync --auto-merge (optional, for automation)
- Detect merge conflicts and provide guidance
- Show commit diff between branches
- Verify main branch is clean before merge
- Push merged changes to remote

Estimated effort: 2-3 days


Graph Link: supersedes for version chains

Implement supersedes link type for version tracking.

New command:
- bd supersede <id> --with <new> - marks id as superseded by new
- Auto-closes the superseded issue

Query support:
- bd show <id> shows 'Superseded by: <new>'
- bd show <new> shows 'Supersedes: <id>'
- bd list --superseded shows version chains

Storage:
- superseded_by column pointing to replacement issue

Useful for design docs, specs, and evolving artifacts.


Fix Homebrew warning about Ruby file location

Homebrew warning: Found Ruby file outside steveyegge/beads tap formula directory.
Warning points to: /opt/homebrew/Library/Taps/steveyegge/homebrew-beads/bd.rb
It should likely be inside a Formula/ directory or similar structure expected by Homebrew taps.


Expand checkHooksQuick to verify all hook versions

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


DetectCycles SQL query has bug preventing cycle detection

The DetectCycles function's SQL query has a bug in the LIKE filter that prevents it from detecting cycles.

Current code (line 571):
```sql
AND p.path NOT LIKE '%' || d.depends_on_id || '→%'
```

This prevents ANY revisit to nodes, including returning to the start node to complete a cycle.

Fix:
```sql
AND (d.depends_on_id = p.start_id OR p.path NOT LIKE '%' || d.depends_on_id || '→%')
```

This allows revisiting the start node (to detect the cycle) while still preventing intermediate node revisits.

Impact: Currently DetectCycles cannot detect any cycles, but this hasn't been noticed because AddDependency prevents cycles from being created. The function would only matter if cycles were manually inserted into the database.


Split test suites: fast vs. integration

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

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

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

Recurring dirty state after merge conflicts - bd sync keeps failing

## Problem

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

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

## Root Cause

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

## Current Workaround

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

## Example Session

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

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

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

## Lost Data in Recent Session

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

## Potential Solutions

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

## Related Issues

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

## Solution Implemented

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

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

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

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

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

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

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


bd find-duplicates - AI-powered duplicate detection

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


Command Set Standardization & Flag Consistency

Comprehensive improvements to bd command set based on 2025 audit findings.

## Background
See docs/command-audit-2025.md for detailed analysis.

## Goals
1. Standardize flag naming and behavior across all commands
2. Add missing flags for feature parity
3. Fix naming confusion
4. Improve consistency in JSON output

## Success Criteria
- All mutating commands support --dry-run (no --preview variants)
- bd update supports label operations
- bd search has filter parity with bd list
- Priority flags accept both int and P0-P4 format everywhere
- JSON output is consistent across all commands


bd import fails on duplicate external_ref with no resolution options

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

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

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

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


Production Readiness (Optional)

Enable multi-machine deployments with containerization and monitoring.


Implement filesystem shims for WASM

WASM needs JS shims for filesystem access. Child of epic bd-44d0.

## Tasks
- [ ] Implement file read/write shims
- [ ] Map WASM syscalls to Node.js fs API
- [ ] Handle .beads/ directory discovery
- [ ] Test with real JSONL files
- [ ] Support both absolute and relative paths

## Technical Notes
- Use Node.js fs module via syscall/js
- Consider MEMFS for in-memory option


Unit tests for Debouncer

Test debouncer batches multiple triggers into single action. Test timer reset on subsequent triggers. Test cancel during wait. Test thread safety.


Database import silently fails when daemon version != CLI version


Issue with desc

This is a description


Consider extracting error handling helpers

Evaluate creating FatalError() and WarnError() helpers as suggested in ERROR_HANDLING.md to reduce boilerplate and enforce consistency. Prototype in a few files first to validate the approach.


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.


Add import metrics for external_ref matching statistics

Add observability for external_ref matching behavior during imports to help debug and optimize import operations.

Metrics to track:
- Number of issues matched by external_ref
- Number of issues matched by ID
- Number of issues matched by content hash
- Number of external_ref updates vs creates
- Average import time with vs without external_ref

Output format:
- Add to ImportResult struct
- Include in import command output
- Consider structured logging

Use cases:
- Debugging slow imports
- Understanding match distribution
- Optimizing import performance

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.


Add comprehensive tests for sync branch daemon logic

The daemon sync branch functionality (bd-6545) was implemented but needs proper end-to-end testing.

Current implementation:
- daemon_sync_branch.go has syncBranchCommitAndPush() and syncBranchPull()
- daemon_sync.go has been updated to use these functions when sync.branch is configured
- All daemon tests pass, but no specific tests for sync branch behavior

Testing needed:
- Test that daemon commits to sync branch when sync.branch is configured
- Test that daemon commits to current branch when sync.branch is NOT configured (backward compatibility)
- Test that daemon pulls from sync branch and syncs JSONL back to main repo
- Test worktree creation and health checks during daemon operations
- Test error handling (missing branch, worktree corruption, etc.)

Key challenge: Tests need to run in the context of the git repo (getGitRoot() uses current working directory), so test setup needs to properly change directory or mock the git root detection.

Reference existing daemon tests in daemon_test.go and daemon_autoimport_test.go for patterns.


Fix CI failures before 0.21.3 release

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

Need to fix before tagging v0.21.3 release.

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


No logging/debugging for tombstone resurrection events

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


Add tests for helper functions (GetDirtyIssueHash, GetAllDependencyRecords, export hashes)

Several utility functions have 0% coverage:
- GetDirtyIssueHash (dirty.go)
- GetAllDependencyRecords (dependencies.go)
- GetExportHash, SetExportHash, ClearAllExportHashes (hash.go)

These are lower priority but should have basic coverage.


Add unit tests for import ordering

Test topological sort: import [child, parent] should succeed, import [parent.1.2, parent, parent.1] should sort correctly. Verify depth-based batching works. Test max depth limits.


Add WaitGroup tracking to FileWatcher goroutines

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

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

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

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

Impact: Race condition on daemon shutdown; potential panic

Effort: 2 hours


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


Create cmd/bd/daemon_debouncer.go (~60 LOC)

Implement Debouncer to batch rapid events into single action. Default 500ms, configurable via BEADS_DEBOUNCE_MS. Thread-safe with mutex.


Add close_reason field to CLI schema and documentation

PR #551 persists close_reason, but the CLI documentation may not mention this field as part of the issue schema.

## Current State
- close_reason is now persisted in database
- `bd show --json` will return close_reason in JSON output
- Documentation may not reflect this new field

## What's Missing
- CLI reference documentation for close_reason field
- Schema documentation showing close_reason is a top-level issue field
- Example output showing close_reason in bd show --json
- bd close command documentation should mention close_reason parameter is optional

## Suggested Action
1. Update README.md or CLI reference docs to list close_reason as an issue field
2. Add example to bd close documentation
3. Update any type definitions or schema specs
4. Consider adding close_reason to verbose list output (bd list --verbose)

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.


Add close_reason to JSONL export format documentation

PR #551 now persists close_reason to the database, but there's a question about whether this field should be exported to JSONL format.

## Current State
- close_reason is stored in issues.close_reason column
- close_reason is also stored in events table (audit trail)
- The JSONL export format may or may not include close_reason

## Questions
1. Should close_reason be exported to JSONL format?
2. If yes, where should it go (root level or nested in events)?
3. Should there be any special handling to avoid duplication?
4. How should close_reason be handled during JSONL import?

## Why This Matters
- JSONL is the git-friendly sync format
- Other beads instances import from JSONL
- close_reason is meaningful data that should be preserved across clones

## Suggested Action
- Check if close_reason is currently exported in JSONL
- If not, add it to the export schema
- Document the field in JSONL format spec
- Add tests for round-trip (export -> import -> verify close_reason)


Integration Layer Implementation

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

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


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


Build Node.js CLI wrapper for WASM

Create npm package that wraps bd.wasm. Child of epic bd-44d0.

## Tasks
- [ ] Set up npm package structure (package.json)
- [ ] Implement CLI argument parsing
- [ ] Load and execute WASM module
- [ ] Handle stdout/stderr correctly
- [ ] Support --json flag for all commands
- [ ] Add bd-wasm bin script

## Success Criteria
- bd-wasm ready --json works identically to bd
- All core commands supported


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


Assigned issue


Add is_tombstone flag to schema

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


bd hooks install fails in git worktrees

When bd is used in a git worktree, bd hooks install fails with 'mkdir .git: not a directory' because .git is a file (gitdir pointer) not a directory. Beads should detect and follow the .git gitdir pointer to install hooks in the correct location. This blocks normal worktree workflows.

## Symptoms of this bug:
- Git hooks don't install automatically
- Auto-sync doesn't run (5-second debounce)
- Hash mismatch warnings in bd output
- Daemon fails to start with 'auto_start_failed'

## Workaround:
Use `git rev-parse --git-dir` to find the actual hooks directory and copy hooks manually:
```bash
mkdir -p $(git rev-parse --git-dir)/hooks
cp -r .beads-hooks/* $(git rev-parse --git-dir)/hooks/
```


Refactor AGENTS.md to use external references

Suggestion to use external references (e.g., "ALWAYS REFER TO ./beads/prompt.md") instead of including all instructions directly within AGENTS.md.
Reasons:
1. Agents can follow external references.
2. Prevents context pollution/stuffing in AGENTS.md as more tools append instructions.


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


Phase 2: Implement sandbox auto-detection for GH #353

Implement automatic sandbox detection to improve UX for users in sandboxed environments (e.g., Codex).

**Tasks:**
1. Implement sandbox detection heuristic using syscall.Kill permission checks
2. Auto-enable --sandbox mode when sandbox is detected
3. Display informative message when sandbox is detected

**Implementation:**
- Add isSandboxed() function in cmd/bd/main.go
- Auto-set sandboxMode = true in PersistentPreRun when detected
- Show: 'ℹ  Sandbox detected, using direct mode'

**References:**
- docs/GH353_INVESTIGATION.md (Solution 3, lines 120-160)
- Depends on: Phase 1 (bd-???)

**Acceptance Criteria:**
- Codex users don't need to manually specify --sandbox
- No false positives in normal environments
- Clear messaging when auto-detection triggers


Multi-repo contributor workflow support

Implement separate repository support for OSS contributors to prevent PR pollution while maintaining git ledger and multi-clone sync. Based on contributor-workflow-analysis.md Solution #4.


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

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

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

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

## Proposed Architecture

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

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

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

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

## Implementation Phases

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

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

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

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

## Risks & Mitigations

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

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

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

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

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

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

bd prime: Detect ephemeral branches and adjust workflow output

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

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

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

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

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

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


Fix row iterator resource leak in recursive dependency queries

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

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

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

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

Impact: Connection exhaustion during dependency traversal


Add optional post-merge git hook example for bd sync

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

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

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

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


bd init should refuse when JSONL already has issues (safety guard)

When running `bd init` in a directory with an existing JSONL containing issues, bd should refuse and suggest the correct action instead of proceeding.

## The Problem

Current behavior when database is missing but JSONL exists:
```
$ bd create "test"
Error: no beads database found
Hint: run 'bd init' to create a database...
```

This leads users (and AI agents) to reflexively run `bd init`, which can cause:
- Prefix mismatch if wrong prefix specified
- Data corruption if JSONL is damaged
- Confusion about what actually happened

## Proposed Behavior

```
$ bd init --prefix bd

⚠ Found existing .beads/issues.jsonl with 76 issues.

This appears to be a fresh clone, not a new project.

To hydrate the database from existing JSONL:
  bd doctor --fix

To force re-initialization (may cause data loss):
  bd init --prefix bd --force

Aborting.
```

## Trigger Conditions

- `.beads/issues.jsonl` or `.beads/beads.jsonl` exists
- File contains > 0 valid issue lines
- No `--force` flag provided

## Edge Cases

- Empty JSONL (0 issues) → allow init (new project)
- Corrupted JSONL → warn but allow with confirmation
- Existing `.db` file → definitely refuse (weird state)

## Related

- bd-dmb: Fresh clone should suggest hydration (better error messages)
- bd-4ew: bd doctor should detect fresh clone

This issue is about the safety guard on `bd init` itself, not the error messages from other commands.


Deletions not propagated across multi-workspace sync

## Problem

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

## Reproduction

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

## Root Cause

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

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

## Solution Options

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

## Related

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


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

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


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

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

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

This prevents stale artifacts from accumulating after daemon crashes.


Add sync.branch configuration

Add configuration layer to support sync.branch setting via config file, environment variable, or CLI flag.

Tasks:
- Add sync.branch field to config schema
- Add BEADS_SYNC_BRANCH environment variable
- Add --branch flag to bd init
- Add bd config get/set sync.branch commands
- Validation (branch name format, conflicts)
- Config migration for existing users

Estimated effort: 1-2 days


Fix mypy errors in beads-mcp

Running `mypy .` in `integrations/beads-mcp` reports 287 errors. These should be addressed to improve type safety and code quality.


Fix: bd migrate-tombstones corrupts deletions manifest

When running 'bd migrate-tombstones' followed by 'bd sync', the operation adds thousands of issues to deletions.jsonl with author 'bd-doctor-hydrate' that should never have been deleted. This causes:
1. Issues are marked as deleted that were never intended for deletion
2. Subsequent 'bd sync' fails with 3-way merge errors
3. The migration operation corrupts database state

## Root Cause
The tombstone migration logic incorrectly identifies issues that should be migrated as 'deleted issues' and adds them to the deletions manifest instead of converting them to inline tombstones.

## Reproduction
1. bd sync --import-only
2. bd migrate-tombstones
3. bd sync
Result: See thousands of 'Skipping bd-xxxx (in deletions manifest: deleted 2025-12-14 by bd-doctor-hydrate)' lines and 3-way merge failures

## Impact
- Database becomes inconsistent
- Issues permanently lost from local database
- Requires full reset to recover

## Files to Investigate
- cmd/bd/migrate_tombstones.go - migration logic
- deletions manifest handling during migration


bd sync outputs excessive 'Skipping' messages for tombstoned issues

During sync, every tombstoned issue outputs a 'Skipping bd-xxx (in deletions manifest)' message. With 96+ tombstones, this creates ~200 lines of noise that obscures the actual sync status.

**Current behavior:**
```
Skipping bd-0ih (in deletions manifest: deleted 0001-01-01 by )
Skipping bd-0is (in deletions manifest: deleted 0001-01-01 by )
... (96 more lines)
✓ Sync complete
```

**Expected behavior:**
- Suppress individual skip messages by default
- Show summary: 'Skipped 96 tombstoned issues'
- Or add --verbose flag to show individual skips

**Impact:** Makes sync output unreadable, hard to spot actual errors or warnings.


Merge3Way public API does not expose TTL parameter

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


Reduce global state in cmd/bd/main.go (25+ variables)

Code health review found main.go has 25+ global variables (lines 57-112):

- dbPath, actor, store, jsonOutput, daemonClient, noDaemon
- rootCtx, rootCancel, autoFlushEnabled
- isDirty (marked 'USED BY LEGACY CODE')
- needsFullExport (marked 'USED BY LEGACY CODE')
- flushTimer (marked 'DEPRECATED')
- flushMutex, storeMutex, storeActive
- flushFailureCount, lastFlushError, flushManager
- skipFinalFlush, autoImportEnabled
- versionUpgradeDetected, previousVersion, upgradeAcknowledged

Impact:
- Hard to test individual commands
- Race conditions possible
- State leakage between commands

Fix: Move toward dependency injection. Remove deprecated variables. Consider cmd/bd/internal package.


GetNextChildID doesn't attempt parent resurrection from JSONL history

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

Related to GH #334 and #278.

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

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

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


bd-hv01: Multi-repo mode not tested with deletion tracking

Problem: Test suite has no coverage for multi-repo mode. ExportToMultiRepo creates multiple JSONL files but snapshot files are hardcoded to single JSONL location.

Impact: Deletion tracking likely silently broken for multi-repo users, could cause data loss.

Fix: Add test and update snapshot logic to handle multiple JSONL files.

Files: cmd/bd/deletion_tracking_test.go, cmd/bd/deletion_tracking.go, cmd/bd/daemon_sync.go:24-34


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.


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

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

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

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

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


GH#508: Orphan detection false positive when directory name contains dot

Directory names with dots trigger orphan issue detection because dot is also used for orphan ID format. bd rename-prefix fixes it. See: https://github.com/steveyegge/beads/issues/508


GH#519: bd sync fails when sync.branch equals current branch

bd sync tries to create worktree when sync.branch matches current checkout, fails with 'already used by worktree'. Should detect and commit directly. See: https://github.com/steveyegge/beads/issues/519


Create cmd/bd/daemon_event_loop.go (~200 LOC)

Implement runEventDrivenLoop to replace polling ticker. Coordinate FileWatcher, mutation events, debouncer. Include health check ticker (60s) for daemon validation.


Add validation and documentation for metadata key format

## Issues

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

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

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

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

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


CLI accepts both hash IDs and aliases

Update all CLI commands to accept both hash IDs (bd-af78e9a2) and aliases (#42, or just 42).

## Parsing Logic
```go
// internal/utils/id_parser.go
func ParseIssueID(input string) (issueID string, err error) {
    // Hash ID: bd-af78e9a2
    if strings.HasPrefix(input, "bd-") {
        return input, nil
    }

    // Alias: #42 or 42
    aliasStr := strings.TrimPrefix(input, "#")
    alias, err := strconv.Atoi(aliasStr)
    if err != nil {
        return "", fmt.Errorf("invalid issue ID: %s", input)
    }

    // Resolve alias to hash ID
    return storage.GetIssueIDByAlias(alias)
}
```

## Commands to Update
All commands that accept issue IDs:

### 1. bd show
```bash
bd show bd-af78e9a2        # Hash ID
bd show #42                # Alias
bd show 42                 # Alias (shorthand)
bd show bd-af78e9a2 #42    # Mixed (multiple IDs)
```

### 2. bd update
```bash
bd update #42 --status in_progress
bd update bd-af78e9a2 --priority 1
```

### 3. bd close
```bash
bd close #42 --reason "Done"
```

### 4. bd dep add/tree
```bash
bd dep add #42 #1 --type blocks
bd dep tree bd-af78e9a2
```

### 5. bd label add/remove
```bash
bd label add #42 critical
```

### 6. bd merge
```bash
bd merge #42 #43 --into #41
```

## Display Format
Default to showing aliases in output:
```bash
$ bd list
#1   Fix authentication bug          P1  open
#2   Add logging to daemon           P2  open
#42  Investigate jujutsu integration P3  open
```

With `--format=hash` flag:
```bash
$ bd list --format=hash
bd-af78e9a2  Fix authentication bug          P1  open
bd-e5f6a7b8  Add logging to daemon           P2  open
bd-1a2b3c4d  Investigate jujutsu integration P3  open
```

## Files to Modify
- internal/utils/id_parser.go (new)
- cmd/bd/show.go
- cmd/bd/update.go
- cmd/bd/close.go
- cmd/bd/reopen.go
- cmd/bd/dep.go
- cmd/bd/label.go
- cmd/bd/merge.go
- cmd/bd/list.go (add --format flag)

## Testing
- Test hash ID parsing
- Test alias parsing (#42, 42)
- Test mixed IDs in single command
- Test error on invalid ID
- Test alias resolution failure


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

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

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

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


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.

Document BEADS_DIR pattern for multi-agent workspaces (Gas Town)

Gas Town and similar multi-agent systems need to configure separate beads databases per workspace/rig, distinct from any project-level beads.

## Use Case

In Gas Town:
- Each 'rig' (managed project) has multiple agents (polecats, refinery, witness)
- All agents in a rig should share a single beads database at the rig level
- This should be separate from any .beads/ the project itself uses
- The BEADS_DIR env var enables this

## Documentation Needed

1. Add a section to docs explaining BEADS_DIR for multi-agent setups
2. Example: setting BEADS_DIR in agent startup scripts/hooks
3. Clarify interaction with project-level .beads/ (BEADS_DIR takes precedence)

## Current Support

Already implemented in internal/beads/beads.go:FindDatabasePath():
- BEADS_DIR env var is checked first (preferred)
- BEADS_DB env var still supported (deprecated)
- Falls back to .beads/ search in tree

Just needs documentation for the multi-agent workspace pattern.


Platform tests: Linux, macOS, Windows

Test event-driven mode on all platforms. Verify inotify (Linux), FSEvents (macOS), ReadDirectoryChangesW (Windows). Test fallback behavior on each.

**Tasks:**
1. Create or update TROUBLESHOOTING.md with sandbox section
2. Document new flags in CLI reference
3. Add comment to GH #353 with immediate workarounds

**Content needed:**
- Symptoms of daemon lock issues in sandboxed environments
- Usage guide for --sandbox, --force, and --allow-stale flags
- Step-by-step troubleshooting for Codex users
- Examples of each escape hatch

**Files to update:**

Graph Link: duplicates for deduplication

Implement duplicates link type for marking issues as duplicates.

New command:
- bd duplicate <id> --of <canonical> - marks id as duplicate of canonical
- Auto-closes the duplicate issue

Query support:
- bd show <id> shows 'Duplicate of: <canonical>'
- bd list --duplicates shows all duplicate pairs

Storage:
- duplicates column pointing to canonical issue ID

Essential for large issue databases with many similar reports.


GH#505: Add bd reset/wipe command

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


bd export only outputs 1 issue after auto-import corrupts database

When auto-import runs and purges issues (due to git history backfill bug), subsequent 'bd export' only exports 1 issue even though the database should have many.

Reproduction:
1. Have issues.jsonl with 55 issues
2. Auto-import triggers and purges all issues via git history backfill
3. Run 'bd export' - only exports 1 issue (the last one created before corruption)

The database gets into an inconsistent state where most issues are purged but export doesn't realize this.

Workaround: Rebuild database from scratch with 'rm .beads/beads.db && bd init --prefix bd'


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

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

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

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

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

## Potential Followups
See linked issues for suggestions.

npm package for bd with native binaries

Create an npm package that wraps native bd binaries for easy installation in Claude Code for Web and other Node.js environments.

## Problem
Claude Code for Web sandboxes are full Linux VMs with npm support, but cannot easily download binaries from GitHub releases due to network restrictions or tooling limitations.

## Solution
Publish bd as an npm package that:
- Downloads platform-specific native binaries during postinstall
- Provides a CLI wrapper that invokes the native binary
- Works seamlessly in Claude Code for Web SessionStart hooks
- Maintains full feature parity (uses native SQLite)

## Benefits vs WASM
- ✅ Full SQLite support (no custom VFS needed)
- ✅ All features work identically to native bd
- ✅ Better performance (native vs WASM overhead)
- ✅ ~4 hours effort vs ~2 days for WASM
- ✅ Minimal maintenance burden

## Success Criteria
- npm install @beads/bd works in Claude Code for Web
- All bd commands function identically to native binary
- SessionStart hook documented for auto-installation
- Package published to npm registry

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


Address gosec security warnings (102 issues)

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


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.


GH#540: Add silent quick-capture mode (bd q)

Add bd q alias for quick capture that outputs only issue ID. Useful for piping/scripting. See GitHub issue #540.


Improve test coverage for internal/export (37.1% → 60%)

The export package has only 37.1% test coverage. Export functionality needs good coverage to ensure data integrity.

Current coverage: 37.1%
Target coverage: 60%


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


Document Claude Code for Web SessionStart hook

Create documentation for using bd in Claude Code for Web:

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

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

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

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


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.

- Bundle size <10MB


Implement health checks in daemon event loop

Add health checks to checkDaemonHealth() function in daemon_event_loop.go:170:
- Database integrity check
- Disk space check
- Memory usage check

Currently it's just a no-op placeholder.


Code Health & Technical Debt Cleanup

Comprehensive codebase cleanup to remove dead code, refactor monolithic files, deduplicate utilities, and improve maintainability. Based on ultrathink code health analysis conducted 2025-10-27.

Goals:
- Remove ~1,500 LOC of dead/unreachable code
- Split 2 monolithic files (server.go 2,273 LOC, sqlite.go 2,136 LOC) into focused modules
- Deduplicate scattered utility functions (normalizeLabels, BD_DEBUG checks)
- Consolidate test coverage (2,019 LOC of collision tests)
- Improve code navigation and reduce merge conflicts

Impact: Reduces codebase by ~6-8%, improves maintainability, faster CI/CD

Estimated Effort: 11 days across 4 phases


Q4 Platform Improvements


Wrap git operations in GitClient interface

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


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

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


Test RPC mutation event


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

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

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

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

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


Fix silent error handling in RPC response writing

Marshal and write errors silently ignored in writeResponse, can send partial JSON and hang clients.

Location: internal/rpc/server_lifecycle_conn.go:228-232

Problem:
- json.Marshal error ignored - cyclic reference sends corrupt JSON
- Write error ignored - connection closed, no indication to caller
- WriteByte error ignored - client hangs waiting for newline
- Flush error ignored - partial data buffered

Current code:
func (s *Server) writeResponse(writer *bufio.Writer, resp Response) {
    data, _ := json.Marshal(resp)  // Ignored!
    _, _ = writer.Write(data)      // Ignored!
    _ = writer.WriteByte('\n')     // Ignored!
    _ = writer.Flush()             // Ignored!
}

Solution: Return errors, handle in caller, close connection on error

Impact: Client hangs waiting for response; corrupt JSON sent

Effort: 1 hour


Investigate and optimize test suite performance

Test suite is taking very long to run (>45s for cmd/bd tests, full suite timing unknown but was cancelled).

This impacts development velocity and CI/CD performance.

Investigation needed:
- Profile which tests are slowest
- Identify bottlenecks (disk I/O, network, excessive setup/teardown?)
- Consider parallelization opportunities
- Look for redundant test cases
- Check if integration tests can be optimized


Fix variable shadowing in GetNextChildID resurrection code

## Problem
Minor variable shadowing in hash_ids.go:

```go
// Line 33: err declared here
err := s.db.QueryRowContext(ctx, `SELECT COUNT(*) FROM issues WHERE id = ?`, parentID).Scan(&count)

// Line 38: err reused/shadowed here
resurrected, err := s.TryResurrectParent(ctx, parentID)
```

While Go allows this, it can be confusing and some linters flag it.

## Solution
Use different variable name:

```go
resurrected, resurrectErr := s.TryResurrectParent(ctx, parentID)
if resurrectErr != nil {
    return "", fmt.Errorf("failed to resurrect parent %s: %w", parentID, resurrectErr)
}
```

## Files
- internal/storage/sqlite/hash_ids.go:38

## Priority
Low - code works correctly, just a style improvement


Add tests for 3-way merge scenarios

Comprehensive test coverage for merge logic.

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

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


Migration guide documentation

Write comprehensive migration guide covering: OSS contributor workflow, team workflow, multi-phase development, multiple personas. Include step-by-step instructions, troubleshooting, and backward compatibility notes.


Update documentation for beads-merge integration

Document the integrated merge functionality.

**Updates needed**:
- AGENTS.md: Replace "use external beads-merge" with "bd merge"
- README.md: Add git merge driver section
- TROUBLESHOOTING.md: Update merge conflict resolution
- ADVANCED.md: Document 3-way merge algorithm
- Create CREDITS.md or ATTRIBUTION.md for @neongreen

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


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

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

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

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


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


Issue 1 to reopen


Extract validation functions to validators.go

Move validatePriority, validateStatus, validateIssueType, validateTitle, validateEstimatedMinutes, validateFieldUpdate to validators.go


Add concurrent import race condition tests

Currently no tests verify behavior when multiple clones import simultaneously with external_ref matching.

Scenarios to test:
1. Two clones import same external_ref update at same time
2. Clone A imports while Clone B updates same issue
3. Verify transaction isolation prevents corruption
4. Document expected behavior (last-write-wins vs timestamp-based)

Related: bd-1022
Files: internal/importer/external_ref_test.go


GH#409: bd init uses issues.jsonl but docs say beads.jsonl

bd init creates config referencing issues.jsonl but README/docs reference beads.jsonl as canonical. Standardize naming. See GitHub issue #409.


Add tests for daemon sync module


Improve compact/daemon/merge documentation and UX

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

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


Workaround for FastMCP outputSchema bug in Claude Code

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

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

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

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


Fix TestTwoCloneCollision to compare content not timestamps

The test at beads_twoclone_test.go:204-207 currently compares full JSON output including timestamps, causing false negative failures.

Current behavior:
- Both clones converge to identical semantic content
- Clone A: test-2="Issue from clone A", test-1="Issue from clone B"
- Clone B: test-1="Issue from clone B", test-2="Issue from clone A"
- Titles match IDs correctly, no data corruption
- Only timestamps differ (expected and acceptable)

Fix needed:
- Replace exact JSON comparison with content-aware comparison
- Normalize or ignore timestamp fields when asserting convergence
- Test should PASS after this fix

This blocks completion of bd-71107098.
