Design tombstone merge semantics

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


Tombstone fields not merged in mergeIssue function

The mergeIssue() function in merge.go does not handle tombstone fields (DeletedAt, DeletedBy, DeleteReason, OriginalType) when merging live issues. While tombstones are handled separately in merge3WayWithTTL(), if a tombstone ever reaches mergeIssue() via the mergeStatus safety fallback, the tombstone fields would be lost. The mergeIssue() function should either: 1) Copy tombstone fields when result.Status becomes tombstone, or 2) Assert that tombstones never reach mergeIssue() (defensive check).

Add bd reset command for clean slate restart

Implement a `bd reset` command to reset beads to a clean starting state.

## Context
GitHub issue #479 - users sometimes get beads into an invalid state after updates, and there's no clean way to start fresh. The git backup/restore mechanism that protects against accidental deletion also makes it hard to intentionally reset.

## Design

### Command Interface
```
bd reset [--hard] [--force] [--backup] [--dry-run] [--no-init]
```

| Flag | Effect |
|------|--------|
| `--hard` | Also remove from git index and commit |
| `--force` | Skip confirmation prompt |
| `--backup` | Create `.beads-backup-{timestamp}/` first |
| `--dry-run` | Preview what would happen |
| `--no-init` | Don't re-initialize after clearing |

### Reset Levels
1. **Soft Reset (default)** - Kill daemons, clear .beads/, re-init. Git history unchanged.
2. **Hard Reset (`--hard`)** - Also git rm and commit the removal, then commit fresh state.

### Implementation Flow
1. Validate .beads/ exists
2. If not --force: show impact summary, prompt confirmation
3. If --backup: copy .beads/ to .beads-backup-{timestamp}/
4. Kill daemons
5. If --hard: git rm + commit
6. rm -rf .beads/*
7. If not --no-init: bd init (and git add+commit if --hard)
8. Print summary

### Safety Mechanisms
- Confirmation prompt (skip with --force)
- Impact summary (issue/tombstone counts)
- Backup option
- Dry-run preview
- Git dirty check warning

### Code Structure
- `cmd/bd/reset.go` - CLI command
- `internal/reset/` - Core logic package


Consider using types.Status in merge package for type safety

The merge package uses string for status comparison (e.g., result.Status == closed, issue.Status == StatusTombstone). The types package defines Status as a type alias with validation. While the merge package needs its own Issue struct for JSONL flexibility, it could import and use types.Status for constants to get compile-time type checking. Current code: if left == closed || right == closed. Could be: if left == string(types.StatusClosed). This is low priority since string comparison works correctly. Files: internal/merge/merge.go:44, 488, 501-521


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

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


Document bd-wasm installation and usage

Create documentation for bd-wasm:
- Update README with npm installation instructions
- Add troubleshooting section for WASM-specific issues
- Document known limitations vs native bd
- Add examples for Claude Code Web sandbox usage
- Update INSTALLING.md with bd-wasm option


Fix unparam unused parameter in cmd/bd/doctor.go:1879

Linting issue: checkGitHooks - path is unused (unparam) at cmd/bd/doctor.go:1879:20. Error: func checkGitHooks(path string) doctorCheck {


Separate process/lock/PID concerns into process.go

Create internal/daemonrunner/process.go with: acquireDaemonLock, PID file read/write, stopDaemon, isDaemonRunning, getPIDFilePath, socket path helpers, version check.


Update documentation for merge driver auto-config

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

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

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


Update documentation for bd prime and Claude integration

Update AGENTS.md, README.md, and QUICKSTART.md to document the new `bd prime` command, `bd setup claude` command, and tip system.


Update 3-way merge to handle tombstones

Modify internal/merge/merge.go to detect tombstones, implement tombstone-wins-unless-expired logic, add TTL parameter to merge functions. Per design bd-zvg.


Mass deletion logging for forensics

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

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

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

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


Multi-repo hydration layer

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


Stealth mode global gitignore should use absolute project path

**GitHub Issue:** #538

**Problem:**
`bd init --stealth` adds `.beads/` to the global gitignore, which ignores ALL `.beads/` folders across all repositories. Users who want stealth mode in one project but open beads usage in others are blocked.

**Solution:**
Change stealth mode to use absolute paths instead of generic patterns:

**Before (current):**
```
# Beads stealth mode configuration (added by bd init --stealth)
.beads/
.claude/settings.local.json
```

**After (proposed):**
```
# Beads stealth mode: /Users/foo/work-project (added by bd init --stealth)
/Users/foo/work-project/.beads/
/Users/foo/work-project/.claude/settings.local.json
```

**Implementation:**
1. Modify `setupGlobalGitIgnore()` in `cmd/bd/init.go`
2. Get current working directory (absolute path)
3. Use absolute path patterns instead of generic ones
4. Update comment to show which project the entry is for

**Tradeoffs:**
- If project directory moves, gitignore entry becomes stale (acceptable - user can re-run `bd init --stealth`)
- Multiple stealth projects = multiple entries (works correctly)

**Testing:**
- Verify absolute path is added to global gitignore
- Verify other projects' .beads/ folders are NOT ignored
- Test with existing global gitignore file
- Test creating new global gitignore file


Implement TryResurrectParent function

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


Import validation falsely reports data loss on collision resolution

## Problem

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

## Example

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

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

## Impact

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

## Solution

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

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


Vendor beads-merge Go code into internal/merge/

Copy beads-merge source code from @neongreen's repo into bd codebase.

**Tasks**:
- Create `internal/merge/` package
- Copy merge algorithm code
- Add attribution header to all files
- Update imports to use bd's internal types
- Add LICENSE/ATTRIBUTION file crediting @neongreen
- Keep original algorithm intact

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


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)

Remove misleading placeholder 'bd merge' command from duplicates output

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

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

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

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

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

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

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


bd doctor: handle missing daemon registry gracefully

When no daemon has ever been started, bd doctor shows an error parsing the registry: 'failed to parse registry: invalid character 0 after top-level value'. The doctor should handle the case where ~/.bd/daemon/registry.json doesn't exist, treating it as 'no daemon running' rather than an error.


Test issue 2


Add embedding generation for duplicate detection

Use embeddings for scalable duplicate detection.

Model: text-embedding-3-small (OpenAI) or all-MiniLM-L6-v2 (local)
Storage: SQLite vector extension or in-memory
Cost: ~/bin/bash.0002 per 100 issues

Much cheaper than LLM comparisons for large databases.

Files: internal/embeddings/ (new package)


Test Agent Mail server failure scenarios

Verify graceful degradation across various failure modes.

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

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

File: tests/integration/test_mail_failures.py


Registry has cross-process race condition

The global daemon registry (~/.beads/registry.json) can be corrupted when multiple daemons from different workspaces write simultaneously.

**Root cause:**
- Registry uses an in-process mutex but no file-level locking
- Register() and Unregister() release the mutex between read and write
- Multiple daemon processes can interleave their read-modify-write cycles

**Evidence:**
Found registry.json with double closing bracket: `]]` instead of `]`

**Fix options:**
1. Use file locking (flock/fcntl) around the entire read-modify-write cycle
2. Use atomic write pattern (write to temp file, rename)
3. Both (belt and suspenders)

**Files:**
- internal/daemon/registry.go:46-64 (readEntries)
- internal/daemon/registry.go:67-87 (writeEntries)
- internal/daemon/registry.go:90-108 (Register - the race window)

Implement transaction retry logic for SQLITE_BUSY

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

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

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

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

Impact: Spurious failures under concurrent write load

Effort: 3 hours

Create npm package structure with package.json

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

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

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

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


Fix TestMigrateHashIDs test failure

Test failure in cmd/bd/migrate_hash_ids_test.go:100 - New ID bd-09970281 for bd-1 is not a hash ID. This test is validating the hash ID migration but the generated ID doesn't match the expected format.

Fix hasJSONLChanged to support per-repo metadata keys

## Problem
After bd-ar2.2, we store metadata with per-repo keys like `last_import_hash:<path>`, but `hasJSONLChanged` and `validatePreExport` still only check global keys.

## Impact
- Multi-repo mode won't benefit from bd-ymj fix
- validatePreExport will fail incorrectly or pass incorrectly
- Metadata updates are written but never read

## Location
- cmd/bd/integrity.go:97 (hasJSONLChanged)
- cmd/bd/integrity.go:138 (validatePreExport)

## Solution
Update hasJSONLChanged to accept optional keySuffix parameter:
```go
func hasJSONLChanged(ctx context.Context, store storage.Storage, jsonlPath string, keySuffix string) bool {
    // Build metadata keys with optional suffix
    hashKey := "last_import_hash"
    mtimeKey := "last_import_mtime"
    if keySuffix != "" {
        hashKey += ":" + keySuffix
        mtimeKey += ":" + keySuffix
    }
    // ... rest of function
}
```

Update all callers to pass correct keySuffix.

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

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


bd find-duplicates - AI-powered duplicate detection

Find semantically duplicate issues.

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

Uses embeddings by default for >100 issues.

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


Add 'bd status' command for issue database overview

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

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

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

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

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


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.

Fix revive style issues (78 issues)

Style violations: unused parameters (many cmd/args in cobra commands), missing exported comments, stuttering names (SQLiteStorage), indent-error-flow issues.

Fixed 19 revive issues:
- 14 unused-parameter (renamed to _)
- 2 redefines-builtin-id (max→maxCount, min→minInt)
- 3 indent-error-flow (gofmt fixed 2, skipped 1 complex nested one)

Remaining issues are acceptable: 11 unused-params in deeper code, 2 empty-blocks with comments, 1 complex indent case, 1 superfluous-else in test.


Add tombstone validation: require deleted_at for tombstone status

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

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

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


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.


fix: bd onboard hangs on Windows


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

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

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

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

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

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

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


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

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

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

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

Add template support for issue creation

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

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

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

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

Fix Nix flake build test failures

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

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

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


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 transaction conflict in TryResurrectParent

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

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

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

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

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


Extract daemon server functions to daemon_server.go


Refactor daemon local-only sync functions to reduce duplication

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


Update git hooks to be sync.branch aware

## Problem

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

## Current Behavior

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

## Expected Behavior

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

## Affected Files

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

## Workaround

Use git push --no-verify


GH#486: Claude forgets beads workflow mid-session

Claude progressively reverts to TodoWrite or skips tracking despite CLAUDE.md instructions. Happens after context resets or long sessions. Need stronger prompting or hooks. See: https://github.com/steveyegge/beads/issues/486


Test simple issue


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

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

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

See repair_commands.md lines 125-353 for design.


Daemon race condition: stale export overwrites recent DB changes

**Symptom:**
Merged bd-fc2d into bd-fb05 in ~/src/beads (commit ce4d756), pushed to remote. The ~/src/fred/beads daemon then exported its stale DB state and committed (8cc1bb4), reverting bd-fc2d back to "open" status.

**Timeline:**
1. 21:45:12 - Merge committed from ~/src/beads (ce4d756): bd-fc2d closed
2. 21:49:42 - Daemon in ~/src/fred/beads exported stale state (8cc1bb4): bd-fc2d open again

**Root cause:**
The fred/beads daemon had a stale database (bd-fc2d still open) and didn't auto-import the newer JSONL before exporting. When it exported, it overwrote the merge with its stale state.

**Expected behavior:**
Daemon should detect that JSONL is newer than its last export and import before exporting.

**Actual behavior:**
Daemon exported stale DB state, creating a conflicting commit that reverted upstream changes.

**Impact:**
Multi-workspace setups with daemons can silently lose changes if one daemon has stale state and exports.


Add edge case tests for GetNextChildID parent resurrection

## Current Coverage
TestGetNextChildID_ResurrectParent tests happy path only:
- Parent exists in JSONL
- Resurrection succeeds

## Missing Test Cases

### 1. Parent Not in JSONL
- Parent doesn't exist in DB
- Parent doesn't exist in JSONL either
- Should return: "could not be resurrected from JSONL history"

### 2. JSONL File Missing
- Parent doesn't exist in DB
- No issues.jsonl file exists
- Should handle gracefully

### 3. Malformed JSONL
- Parent doesn't exist in DB
- JSONL file exists but has invalid JSON
- Should skip bad lines, continue searching

### 4. Concurrent Resurrections
- Multiple goroutines call GetNextChildID with same parent
- Only one should resurrect, others should succeed
- Test for race conditions

### 5. Deeply Nested Missing Parents
- Creating bd-abc.1.2.1 where:
  - bd-abc exists
  - bd-abc.1 missing (should fail with current fix)
- Related to bd-ar2.4

### 6. Content Hash Mismatch
- Parent in JSONL has different content_hash than expected
- Should still resurrect (content_hash is for integrity, not identity)

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

## Implementation
```go
func TestGetNextChildID_ResurrectParent_NotInJSONL(t *testing.T) { ... }
func TestGetNextChildID_ResurrectParent_NoJSONL(t *testing.T) { ... }
func TestGetNextChildID_ResurrectParent_MalformedJSONL(t *testing.T) { ... }
func TestGetNextChildID_ResurrectParent_Concurrent(t *testing.T) { ... }
```

Improve bd doctor output formatting for better readability

The current bd doctor output is a wall of text that's hard to process. Consider improvements like:
- Grouping related checks into collapsible sections
- Using color/bold for section headers
- Showing only failures/warnings by default with --verbose for full output
- Better visual hierarchy between major sections
- Summary line at top (e.g., '24 checks passed, 0 warnings, 0 errors')


Inconsistent stderr printing: bd-feh warning still prints directly


Fix TestExportUpdatesMetadata to test actual daemon functions

## Problem
TestExportUpdatesMetadata (daemon_sync_test.go:296) manually replicates the metadata update logic rather than calling the fixed functions (createExportFunc/createSyncFunc).

This means:
- Test verifies the CONCEPT works
- But doesn't verify the IMPLEMENTATION in the actual daemon functions
- If daemon code is wrong, test still passes

## Current Test Flow
```go
// Test does:
exportToJSONLWithStore()  // ← Direct call
// ... manual metadata update ...
exportToJSONLWithStore()  // ← Direct call again
```

## Should Be
```go
// Test should:
createExportFunc(...)()  // ← Call actual daemon function
// ... verify metadata was updated by the function ...
createExportFunc(...)()  // ← Call again, should not fail
```

## Challenge
createExportFunc returns a closure that's run by the daemon. Testing this requires:
- Mock logger
- Proper context setup
- Git operations might need mocking

## Files
- cmd/bd/daemon_sync_test.go

## Acceptance Criteria
- Test calls actual createExportFunc and createSyncFunc
- Test verifies metadata updated by daemon code, not test code
- Both functions tested (export and sync)


Test all core bd commands in WASM for feature parity

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


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

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

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

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


Issue 1


Fix failing integration tests in beads-mcp

The `beads-mcp` test suite has failures in `tests/test_bd_client_integration.py` (assertion error in `test_init_creates_beads_directory`) and errors in `tests/test_worktree_separate_dbs.py` (setup failures finding database). These need to be investigated and fixed to ensure a reliable CI baseline.


Extract daemon lifecycle functions to daemon_lifecycle.go


Remove unreachable utility functions

Several small utility functions are unreachable:

Files to clean:
1. `internal/storage/sqlite/hash.go` - `computeIssueContentHash` (line 17)
   - Check if entire file can be deleted if only contains this function

2. `internal/config/config.go` - `FileUsed` (line 151)
   - Delete unused config helper

3. `cmd/bd/git_sync_test.go` - `verifyIssueOpen` (line 300)
   - Delete dead test helper

4. `internal/compact/haiku.go` - `HaikuClient.SummarizeTier2` (line 81)
   - Tier 2 summarization not implemented
   - Options: implement feature OR delete method

Impact: Removes 50-100 LOC depending on decisions


Add content-addressable identity to Issue type

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

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

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

## Implementation Tasks

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

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

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

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

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

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

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

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

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


Add 'town report' command for aggregated swarm status

## Problem
Getting a full swarm status requires running 6+ commands:
- `town list <rig>` for each rig
- `town mail inbox` as Boss
- `bd list --status=open/in_progress` per rig

This is slow and error-prone for both humans and agents.

## Proposed Solution
Add `town report [RIG]` command that aggregates:
- All rigs with polecat states (running/stopped, awake/asleep)
- Boss inbox summary (unread count, recent senders)
- Aggregate issue counts per rig (open/in_progress/blocked)

Example output:
```
=== beads ===
Polecats: 5 (5 running, 0 stopped)
Issues: 20 open, 0 in_progress, 0 blocked

=== gastown ===
Polecats: 6 (4 running, 2 stopped)
Issues: 0 open, 0 in_progress, 0 blocked

=== Boss Mail ===
Unread: 10 | Total: 22
Recent: rictus (21:19), scrotus (21:14), immortanjoe (21:14)
```

## Acceptance Criteria
- [ ] `town report` shows all rigs
- [ ] `town report <rig>` shows single rig detail
- [ ] Output is concise and scannable
- [ ] Completes in <2 seconds


Add circular dependency detection to bd doctor

Added cycle detection as Check #10 in bd doctor command. Uses same recursive CTE query as DetectCycles() to find circular dependencies. Reports error status with count and fix suggestion if cycles found.


Add bd init --contributor wizard

Interactive wizard for OSS contributor setup. Guides user through: fork workflow setup, separate planning repo configuration, auto-detection of fork relationships, examples of common OSS workflows.


Configure database connection pool limits for daemon mode

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

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

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

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

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

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

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

Effort: 1 hour


Extract validation functions to validators.go

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


Improve CheckStaleness error handling

## Problem

CheckStaleness returns 'false' (not stale) for multiple error conditions instead of returning errors. This masks problems.

**Location:** internal/autoimport/autoimport.go:253-285

## Edge Cases That Return False

1. **Invalid last_import_time format** (line 259-262)
   - Corrupted metadata returns 'not stale'
   - Could show stale data

2. **No JSONL file found** (line 267-277)
   - If glob fails, falls back to 'issues.jsonl'
   - If that's empty, returns 'not stale'

3. **JSONL stat fails** (line 279-282)
   - Permission denied, file missing
   - Returns 'not stale' even though can't verify

## Current Code

```go
lastImportTime, err := time.Parse(time.RFC3339, lastImportStr)
if err \!= nil {
    return false, nil  // ← Should return error
}

// ...

if jsonlPath == "" {
    return false, nil  // ← Should return error
}

stat, err := os.Stat(jsonlPath)
if err \!= nil {
    return false, nil  // ← Should return error
}
```

## Fix

```go
lastImportTime, err := time.Parse(time.RFC3339, lastImportStr)
if err \!= nil {
    return false, fmt.Errorf("corrupted last_import_time: %w", err)
}

// ...

if jsonlPath == "" {
    return false, fmt.Errorf("no JSONL file found")
}

stat, err := os.Stat(jsonlPath)
if err \!= nil {
    return false, fmt.Errorf("cannot stat JSONL: %w", err)
}
```

## Impact
Medium - edge cases are rare but should be handled

## Effort
30 minutes - requires updating callers in RPC server

## Dependencies
Requires: bd-n4td (warning on errors)


bd show --json doesn't include dependency type field

Fix GitHub issue #202. The JSON output from bd show and bd list commands should include the dependency type field (and optionally created_at, created_by) to match internal storage format and enable better tooling integration.

PR #203 updated with cleaner implementation: https://github.com/steveyegge/beads/pull/203

## Final Implementation

Cleanest possible approach - no internal helper methods needed:

**Design:**
- `GetDependenciesWithMetadata()` / `GetDependentsWithMetadata()` - canonical implementations with full SQL query
- `GetDependencies()` / `GetDependents()` - thin wrappers that strip metadata for backward compat
- `scanIssuesWithDependencyType()` - shared helper for scanning rows with dependency type

**Benefits:**
- Single source of truth - the `...WithMetadata()` methods ARE the implementation
- Eliminated ~139 lines of duplicated SQL and scanning code
- All tests passing (14 dependency-related tests)
- Backward compatible
- dependency_type field appears correctly in JSON output

**Note on scan helpers:**
The duplication between `scanIssues()` and `scanIssuesWithDependencyType()` is necessary because they handle different SQL result shapes (16 vs 17 columns). This is justified as they serve fundamentally different purposes based on query structure.


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

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

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

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

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

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


Switch from modernc.org/sqlite to ncruces/go-sqlite3 for WASM support

modernc.org/sqlite depends on modernc.org/libc which has no js/wasm support (platform-specific syscalls). Need to switch to ncruces/go-sqlite3 which wraps a WASM build of SQLite using wazero runtime.

Key differences:
- ncruces/go-sqlite3: Uses WASM build of SQLite + wazero runtime
- modernc.org/sqlite: Pure Go translation, requires libc for syscalls

This is a prerequisite for bd-62a0 (WASM build infrastructure).


Need --no-git-history flag to disable git history backfill during import

During JSONL migration (beads.jsonl → issues.jsonl), the git history backfill mechanism causes data loss by finding issues in the old beads.jsonl git history and incorrectly treating them as deleted.

A --no-git-history flag for 'bd import' and 'bd sync' would allow users to disable the git history fallback when it's causing problems.

Use cases:
- JSONL filename migrations
- Repos with complex git history
- Debugging import issues
- Performance (skip slow git scans)

Use TryResurrectParentChain instead of TryResurrectParent in GetNextChildID

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

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

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

## Solution
Replace TryResurrectParent with TryResurrectParentChain:

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

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

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

## Testing
Add test case for deeply nested resurrection


Fix multi-round convergence for N-way collisions

## Problem

N-way collision resolution is working (IDs get remapped correctly), but clones don't fully converge after a single final pull. Each clone is missing some issues that other clones have.

From TestFiveCloneCollision results:
- Clone A has: A, B
- Clone B has: A, B
- Clone C has: A, B, C
- Clone D has: A, B, C, D
- Clone E has: A, B, C, E

**Expected**: All clones should have A, B, C, D, E after final pull.

## Root Cause

The current sync workflow does:
1. Each clone syncs in order (resolving collisions locally)
2. Final pull to get all changes

But the final pull itself may need import with collision resolution, which creates new commits. These new commits aren't propagated to other clones, so they remain incomplete.

## Proposed Solution

**Option 1: Multi-round final sync**
- After final pull, do additional sync rounds until all clones converge
- Check convergence by comparing issue counts or content hashes
- Maximum N rounds for N clones

**Option 2: Iterative pull-import-push**
- Each clone: pull → import with --resolve-collisions → push
- Repeat until no new changes
- Guaranteed convergence but may create commit spam

**Option 3: Fix auto-import to be truly idempotent**
- Ensure importing same JSONL multiple times produces no new commits
- May require smarter content-based deduplication

## Acceptance Criteria

- TestFiveCloneCollision passes without t.Skip
- All N clones have all N issues after convergence
- Convergence happens in bounded rounds (≤ N)
- No data loss or duplication
- Works for arbitrary N (tested with 5, 10 clones)

## Impact

This is the final blocker for bd-cbed9619 epic completion.


Fix bd sync race condition with daemon causing dirty working directory

After bd sync completes with sync.branch mode, subsequent bd commands or daemon file watcher would see a hash mismatch and trigger auto-import, which then schedules re-export, dirtying the working directory.

**Root cause:**
1. bd sync exports JSONL with NEW content (hash H1)
2. bd sync updates jsonl_content_hash = H1 in DB
3. bd sync restores JSONL from HEAD (OLD content, hash H0)
4. Now: file hash = H0, DB hash = H1 (MISMATCH)
5. Daemon or next CLI command sees mismatch, imports from OLD JSONL
6. Import triggers re-export → file is dirty

**Fix:**
After restoreBeadsDirFromBranch(), update jsonl_content_hash to match the restored file's hash. This ensures daemon and CLI see file hash = DB hash → no spurious import/export cycle.

Related: bd-c83r (multiple daemon prevention)


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.


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

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

Proposal: Custom status states via config

Proposal to add 'custom status states' via `bd config`.
Users could define an optional issue status enum (e.g., awaiting_review, review_in_progress) in the config.
This would enable multi-step pipelines to process issues where each step correlates to a specific status.

Examples:
- awaiting_verification
- awaiting_docs
- awaiting_testing


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).


bd-hv01: Silent partial deletion failures cause DB inconsistency

Problem: deletion_tracking.go:76-77 logs deletion errors as warnings but continues. If deletion fails midway (database locked, disk full), some issues delete but others don't. System thinks all deletions succeeded.

Impact: Database diverges from JSONL, silent corruption, issues may resurrect on next sync.

Fix: Collect errors and fail the operation:
var deletionErrors []error
for _, id := range acceptedDeletions {
    if err := d.DeleteIssue(ctx, id); err != nil {
        deletionErrors = append(deletionErrors, fmt.Errorf("issue %s: %w", id, err))
    }
}
if len(deletionErrors) > 0 {
    return false, fmt.Errorf("deletion failures: %v", deletionErrors)
}

Latency test manual


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.


Create examples for common workflows

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


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

## Feature Request

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

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

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

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


Final validation test


Refactor daemon.go into internal/daemonrunner

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


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.


Create architecture decision record (ADR)

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

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

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


Auto-routing and maintainer detection

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

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

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

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

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

\`\`\`bash
git pull origin main
bd migrate --hash-ids
git push origin main
\`\`\`

See MIGRATION.md for details.

**Benefits:**
- ✅ No more ID collisions
- ✅ Work offline without coordination
- ✅ Simpler codebase (-2,100 LOC)

Questions? Reply here or see docs/HASH_IDS.md
```

## Success Criteria
- [ ] Migration completes without errors
- [ ] All validation checks pass
- [ ] PR merged to main
- [ ] v2.0.0 tagged and released
- [ ] Documentation updated
- [ ] Community notified
- [ ] No rollback needed within 1 week

Add validation for duplicate external_ref in batch imports

Currently, if a batch import contains multiple issues with the same external_ref, the behavior is undefined. We should detect and handle this case.

Current behavior:
- No validation for duplicate external_ref within a batch
- Last-write-wins or non-deterministic behavior

Proposed solution:
- Detect duplicate external_ref values in incoming batch
- Fail with clear error message OR
- Merge duplicates intelligently (use newest timestamp)
- Add test case for this scenario

Fix compact --analyze/--apply error messages to clarify direct mode requirement

**Problem:**
When users run `bd compact --analyze` with daemon running, they get:
```
Error: compact requires SQLite storage
```

This is misleading because they ARE using SQLite (via daemon), but the command needs DIRECT SQLite access.

**Current behavior:**
- Error message suggests they don't have SQLite
- No hint about using --no-daemon flag
- Related to issue #349 item #1

**Proposed fix:**
1. Update error messages in cmd/bd/compact.go lines 106-114 (analyze) and 121-137 (apply)
2. Add explicit hint: "Use --no-daemon flag to bypass daemon"
3. Change SQLite check error from "requires SQLite storage" to "failed to open database in direct mode"

**Files to modify:**
- cmd/bd/compact.go (lines ~106-137)

**Testing:**
- Run with daemon: `bd compact --analyze` should show clear error + hint
- Run with --no-daemon: `bd compact --analyze --no-daemon` should work
- Verify error message is actionable


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

Integration Testing

Verify cache removal doesn't break any workflows


Add git operations for --hard reset

Implement git integration for hard reset mode.

## Operations Needed
1. `git rm -rf .beads/*.jsonl` - remove data files from index
2. `git commit -m 'beads: reset to clean state'` - commit removal
3. After re-init: `git add .beads/` and commit fresh state

## Edge Cases to Handle
- Uncommitted changes in .beads/ - warn or error
- Detached HEAD state - warn, maybe block
- Git not initialized - skip git ops, warn
- Git operations fail mid-way - clear error messaging

## Interface
```go
type GitState struct {
    IsRepo       bool
    IsDirty      bool   // uncommitted changes in .beads/
    IsDetached   bool   // detached HEAD
    Branch       string // current branch name
}

func CheckGitState(beadsDir string) (*GitState, error)
func GitRemoveBeads(beadsDir string) error
func GitCommitReset(message string) error
func GitAddAndCommit(beadsDir, message string) error
```

## Location
`internal/reset/git.go` - keep with reset package for now

Note: Codebase has no central git package. internal/compact/git.go is compact-specific.
Future refactoring could extract shared git utilities, but YAGNI for now.


sync.branch config lost on clone - should be in config.yaml

## Problem

The sync.branch configuration is stored in the SQLite database, which is gitignored. When contributors clone a repo that uses beads:

1. They get .beads/issues.jsonl (tracked)
2. They don't get .beads/beads.db (gitignored)
3. They lose the sync.branch config

When they run 'bd init' or 'bd doctor --fix', sync.branch gets auto-set to the current branch (usually 'main'), but if the project uses a dedicated sync branch like 'beads-sync', they'll be committing to the wrong branch.

## Root Cause

syncbranch.Get() only checks:
1. BEADS_SYNC_BRANCH env var
2. Database config (store.GetConfig)

It never reads from config.yaml, which IS tracked in git and persists across clones.

## Proposed Solution

Add sync-branch support to config.yaml with this precedence:
1. BEADS_SYNC_BRANCH env var (highest)
2. config.yaml sync-branch setting
3. Database config (legacy/local override)
4. Auto-detect from current branch (lowest)

Changes needed:
1. Update syncbranch.Get() to check config.GetString('sync-branch') between env and database
2. Update config.yaml template in init.go to include sync-branch
3. Update docs to recommend setting sync-branch in config.yaml for team projects
4. Consider: bd init --branch should also write to config.yaml, not just database

Code Review Sweep: thorough

Perform thorough code review sweep based on accumulated activity.

**AI Reasoning:**
Significant code activity with 7608 lines added and 120 files changed indicates substantial modifications. Multiple high-churn areas (cmd/bd, internal/rpc) suggest potential for subtle issues and emerging patterns that warrant review.

**Scope:** thorough
**Target Areas:** cmd/bd, internal/rpc, .beads
**Estimated Files:** 12
**Estimated Cost:** $5

**Task:**
Review files for non-obvious issues that agents miss during focused work:
- Inefficiencies (algorithmic, resource usage)
- Subtle bugs (race conditions, off-by-one, copy-paste)
- Poor patterns (coupling, complexity, duplication)
- Missing best practices (error handling, docs, tests)
- Unnamed anti-patterns

bd sync fails with orphaned issues and duplicate ID conflict

After fixing the deleted_at TEXT column scanning bug (commit 18b1eb2), bd sync still fails with two issues:

1. Orphan Detection Warning: 12 orphaned child issues whose parents no longer exist (bd-cb64c226.* and bd-cbed9619.*)

2. Import Failure: UNIQUE constraint failed for bd-360 - this tombstone exists in both DB and JSONL

Error: "Import failed: error creating depth-0 issues: bulk insert issues: failed to insert issue bd-360: sqlite3: constraint failed: UNIQUE constraint failed: issues.id"

Fix options:
- Delete orphaned child issues with bd delete
- Resolve bd-360 duplicate (in deletions.jsonl vs tombstone in DB)
- Reset sync branch: git branch -f beads-sync main && git push --force-with-lease origin beads-sync

Fixed tombstone constraint violation bug. When deleting closed issues, the CHECK constraint (status = 'closed') = (closed_at IS NOT NULL) was violated because CreateTombstone didn't clear closed_at. Fix: set closed_at = NULL in tombstone creation SQL.

The sync data corruption (orphaned issues in beads-sync branch) requires manual cleanup: reset sync branch with 'git branch -f beads-sync main && git push --force-with-lease origin beads-sync'


Merge timestamp tie-breaker should prefer local (left)

In mergeFieldByUpdatedAt, when timestamps are exactly equal, right wins. For consistency with IssueType (where local/left wins), equal timestamps should prefer left. Minor inconsistency.


Fix: --parent flag doesn't create parent-child dependency

When using `bd create --parent <id>`, the code generates a hierarchical child ID (e.g., bd-123.1) but never creates a parent-child dependency. This causes `bd epic status` to show zero children even though child issues exist.

Root cause: create.go generates child ID using store.GetNextChildID() but never calls store.AddDependency() with type parent-child.

Fix: After creating the issue when parentID is set, automatically add a parent-child dependency linking child -> parent.


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

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

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

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

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


bd sync should not stage gitignored snapshot files

## Problem

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

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

## Root Cause

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

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

## Suggested Fix

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

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

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

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


Switch from deletions manifest to inline tombstones

Replace the current deletions.jsonl manifest with inline tombstone records in issues.jsonl.

## Problem Statement

The current deletions manifest approach has several issues:

1. **Wild poisoning** - A stale clone's deletions manifest can poison fresh databases when synced
2. **Two-level merge inconsistency** - Git content merge and beads snapshot merge use different bases
3. **SyncJSONLToWorktree overwrites** - Blindly copies local JSONL to worktree, losing remote issues
4. **3-day TTL too aggressive** - Deletions expire before dormant branches get merged

## Proposed Solution: Inline Tombstones

Instead of a separate deletions.jsonl file, embed deletion records directly in issues.jsonl:

```json
{"id":"beads-abc","status":"tombstone","title":"Original title","deleted_at":"2025-12-01T...","deleted_by":"user","expires_at":"2025-12-31T..."}
```

### Benefits

1. **Single source of truth** - No separate manifest to sync/merge
2. **Participates in normal 3-way merge** - Deletion conflicts resolved same as other fields
3. **Atomic with issue data** - Can't have orphaned deletions or missing tombstones
4. **Preserves metadata** - Can optionally keep title/type for audit trail

### Design Decisions Needed

1. **TTL duration** - 30 days default? Configurable via config.yaml?
2. **Tombstone content** - Minimal (just ID + timestamps) vs. full issue preservation?
3. **Migration path** - How to handle existing deletions.jsonl files?
4. **Status value** - Use "tombstone" or "deleted"? (tombstone clearer, deleted more intuitive)
5. **Merge semantics** - Does tombstone always win, or use updated_at like other fields?

### Migration Strategy

1. On import, convert deletions.jsonl entries to tombstones in JSONL
2. Deprecate but still read deletions.jsonl for backward compatibility
3. Stop writing to deletions.jsonl after N versions

## Related Issues

- GitHub #464: Beads deletes issues (fresh clone sync problem)
- bd-2e0: Add TTL to deletions manifest entries (current 3-day TTL)
- bd-53c: bd sync corrupts issues.jsonl in multi-clone environments


Add index on deleted_at for TTL queries

Per bd-2m7 design: 'Index for efficient tombstone filtering' was recommended. The current implementation does NOT add an index on deleted_at.

For TTL cleanup queries like 'SELECT * FROM issues WHERE deleted_at < datetime(now, -30 days)', this will require a full table scan.

Add to migration or new migration:
CREATE INDEX IF NOT EXISTS idx_issues_deleted_at ON issues(deleted_at) WHERE deleted_at IS NOT NULL


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

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

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

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

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

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

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

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).


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.


Second worktree test


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

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

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

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


Audit Current Cache Usage

Understand exactly what code depends on the storage cache

AUDIT COMPLETE

getStorageForRequest() callers: 17 production + 11 test
- server_issues_epics.go: 8 calls
- server_labels_deps_comments.go: 4 calls
- server_export_import_auto.go: 2 calls
- server_compact.go: 2 calls
- server_routing_validation_diagnostics.go: 1 call
- server_eviction_test.go: 11 calls (DELETE entire file)

Pattern everywhere: store, err := s.getStorageForRequest(req) → store := s.storage

req.Cwd usage: Only for multi-repo routing. Local daemon always serves 1 repo, so routing is unused.

MCP server: Uses separate daemons per repo (no req.Cwd usage found). NOT affected by cache removal.

Cache env vars to deprecate:
- BEADS_DAEMON_MAX_CACHE_SIZE (used in server_core.go:63)
- BEADS_DAEMON_CACHE_TTL (used in server_core.go:72)
- BEADS_DAEMON_MEMORY_THRESHOLD_MB (used in server_cache_storage.go:47)

Server struct fields to remove:
- storageCache, cacheMu, maxCacheSize, cacheTTL, cleanupTicker, cacheHits, cacheMisses

Tests to delete:
- server_eviction_test.go (entire file - 9 tests)
- limits_test.go cache assertions

Special consideration: ValidateDatabase endpoint uses findDatabaseForCwd() outside cache. Verify if used, then remove or inline.

Safe to proceed with removal - cache always had 1 entry in local daemon model.

Import overwrites newer local issues with older remote versions

## Problem

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

## What Happened

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

## Root Cause

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

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

Import applies incoming version regardless of which is newer.

## Expected Behavior

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

## Solution

Add timestamp checking to DetectCollisions or importIssues:

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

Add MCP server functions for repair commands

Expose new repair commands via MCP server for agent access:

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

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

Implemented all three MCP server functions:

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

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

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

## Problem

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

## Current Behavior

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

## Expected Behavior

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

## Impact

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

## Proposed Solution

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

## Files to Modify

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

## Acceptance Criteria

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

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

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

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

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


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

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

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

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

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


Batch test 4


Improve sync error messages

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


Investigate bd export/import sync issue - database and JSONL out of sync

Observed in VC repo: database has 1137 issues but beads.jsonl only has 309. Running 'bd export -o .beads/issues.jsonl' doesn't update the file. Running 'bd import' hangs indefinitely.

Reproduction context:
- VC repo: 1137 issues in DB, 309 in JSONL
- Created 4 new issues with bd create
- bd export didn't write them to JSONL
- bd import hung (possibly daemon lock conflict?)

Need to investigate:
1. Why export doesn't update JSONL when DB has more issues
2. Why import hangs
3. Daemon lock interaction with export/import
4. File path handling (issues.jsonl vs beads.jsonl)

## Root Cause Analysis

The issue was NOT about file path handling or export failing to update JSONL. The actual problem was:

**Import/Export hanging when daemon is running** due to SQLite lock contention:

1. When daemon is connected, `PersistentPreRun` in main.go returns early without initializing the `store` variable
2. Import/Export commands then tried to open the database directly with `sqlite.New(dbPath)`
3. This blocked waiting for the database lock that the daemon already holds → **HANGS INDEFINITELY**

## Solution Implemented

Modified both import.go and export.go to:
1. Detect when `daemonClient` is connected
2. Explicitly close the daemon connection before opening direct SQLite access
3. Added debug logging to help diagnose similar issues

This ensures import/export commands always run in direct mode, avoiding lock contention.

## File Path Handling

The file path confusion (issues.jsonl vs beads.jsonl) was a red herring. The code uses `filepath.Glob("*.jsonl")` which correctly finds ANY `.jsonl` file in `.beads/` directory, so both filenames work.

AI-supervised database migrations for safer schema evolution

## Problem

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

## Current State

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

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

## Proposal: AI-Supervised Migration Framework

Use AI to supervise migrations through structured verification:

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

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

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

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

## Example Flow

```
$ bd migrate

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

If something goes wrong:
```
$ bd migrate

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

## Implementation Ideas

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

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

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

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

## Benefits

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

## Open Questions

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

Fix validatePreExport to use content hash instead of mtime

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

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

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


Audit remaining cmd/bd files for error handling consistency

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


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


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

Add consistent verbosity controls across all commands.

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

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

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

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

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


Consider consolidating config.yaml parsing into shared utility

Multiple places parse config.yaml with custom structs:

1. **autoimport.go:148** - `localConfig{SyncBranch}`
2. **main.go:310** - strings.Contains for no-db (fragile, see bd-r6k2)
3. **doctor.go:863** - strings.Contains for no-db (fragile, see bd-r6k2)
4. **internal/config/config.go** - Uses viper (but caches at startup, problematic for tests)

Consider creating a shared utility in `internal/configfile/` or extending the viper config:

```go
// internal/configfile/yaml.go
type YAMLConfig struct {
    SyncBranch string `yaml:"sync-branch"`
    NoDb       bool   `yaml:"no-db"`
    IssuePrefix string `yaml:"issue-prefix"`
    Author     string `yaml:"author"`
}

func LoadYAML(beadsDir string) (*YAMLConfig, error) {
    // Parse config.yaml with proper YAML library
}
```

Benefits:
- Single source of truth for config.yaml structure
- Proper YAML parsing everywhere
- Easier to add new config fields

Trade-off: May add complexity for simple one-off reads.


Create npm package structure for bd-wasm

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


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


Modify CreateIssue to support parent resurrection

Update internal/storage/sqlite/sqlite.go:182-196 to call TryResurrectParent before failing on missing parent. Coordinate with EnsureIDs changes for consistent behavior. Handle edge case where parent never existed in JSONL (fail gracefully).


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.


Replace BEADS_DB with BEADS_DIR environment variable

Implement BEADS_DIR as a replacement for BEADS_DB to point to the .beads directory instead of the database file directly.

Rationale:
- With --no-db mode, there's no .db file to point to
- The .beads directory is the logical unit (contains config.yaml, db files, jsonl files)
- More intuitive: point to the beads directory not the database file

Implementation:
1. Add BEADS_DIR environment variable support
2. Maintain backward compatibility with BEADS_DB
3. Priority order: BEADS_DIR > BEADS_DB > auto-discovery
4. If BEADS_DIR is set, look for config.yaml in that directory to find actual database path
5. Update documentation and migration guide

Files to modify:
- beads.go (FindDatabasePath function)
- cmd/bd/main.go (initialization)
- Documentation (CLI_REFERENCE.md, TROUBLESHOOTING.md, etc.)
- MCP integration (integrations/beads-mcp/src/beads_mcp/config.py)

Testing:
- Ensure BEADS_DB still works (backward compatibility)
- Test BEADS_DIR with both db and --no-db modes
- Test priority order when both are set
- Update integration tests

Benchmark Helper Functions

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

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

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

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

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

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

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