Test SQLite WASM compatibility

Verify modernc.org/sqlite works in WASM target. Child of epic bd-44d0.

## Tasks
- [ ] Compile minimal SQLite test to WASM
- [ ] Test database create/open operations
- [ ] Test query execution
- [ ] Test JSONL import/export
- [ ] Benchmark performance vs native

## Decision Point
If modernc.org/sqlite issues, evaluate ncruces/go-sqlite3 alternative.


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.


Add index usage verification test for external_ref lookups

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

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

bd doctor --fix needs non-interactive mode (-y/--yes flag)

When running `bd doctor --fix` in non-interactive mode (scripts, CI, Claude Code), it prompts 'Continue? (Y/n):' and fails with EOF.

**Expected**: A `-y` or `--yes` flag to auto-confirm fixes.

**Workaround**: Currently have to run `bd init` instead, but that's not discoverable from the doctor output.


Add comprehensive tests for show.go commands (show, update, edit, close)

Need to add tests for cmd/bd/show.go which contains show, update, edit, and close commands.

**Challenge**: The existing test patterns use rootCmd.SetArgs() and rootCmd.Execute(), but the global `store` variable needs to match what the commands use. Initial attempt created tests that failed with "no issue found" because the test's store instance wasn't the same as the command's store.

**Files to test**:
- show.go (contains showCmd, updateCmd, editCmd, closeCmd)

**Coverage needed**:
- show command (single issue, multiple issues, JSON output, with dependencies, with labels, with compaction)
- update command (status, priority, title, assignee, description, multiple fields, multiple issues)
- edit command (requires $EDITOR, may need mocking)
- close command (single issue, multiple issues, with reason, JSON output)

**Test approach**:
1. Study working test patterns in init_test.go, list_test.go, etc.
2. Ensure BEADS_NO_DAEMON=1 is set
3. Properly initialize database with bd init
4. Use the command's global store, not a separate instance
5. May need to reset global state between tests

**Success criteria**:
- All test functions pass
- Coverage for show.go increases significantly
- Tests follow existing patterns in cmd/bd/*_test.go


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)


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)


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.


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 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


bd doctor doesn't detect version mismatches or stale daemons


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)
}

Files: cmd/bd/deletion_tracking.go:73-82


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)


Cache getMultiRepoJSONLPaths() result during sync to avoid redundant calls

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

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

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

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

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

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

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

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

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

        // ... later ...

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

        // ... later ...

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

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

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


Change default JSONL filename from beads.jsonl back to issues.jsonl throughout codebase


Investigate performance issues in VS Code Copilot (Windows)

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


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


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


Test npm package installation locally

Verify npm package works before publishing:

## Local testing
- Run npm pack in npm/ directory
- Install tarball globally: npm install -g beads-bd-0.21.5.tgz
- Test basic commands:
  - bd --version
  - bd init --quiet --prefix test
  - bd create "Test issue" -p 1 --json
  - bd list --json
  - bd sync

## Test environments
- macOS (darwin-arm64 and darwin-amd64)
- Linux (ubuntu docker container for linux-amd64)
- Windows (optional, if available)

## Validation
- Binary downloads during postinstall
- All bd commands work identically to native
- No permission issues
- Proper error messages on failure


bd ready taking 5 seconds with 132 issues (89 closed)

User reports bd ready is annoyingly slow on M2 Mac - 5 seconds for 132 issues (89 closed). Started noticing after hash-based IDs update. Need to investigate performance regression. Reported in GH #243.

Root cause identified: Not a query performance issue, but stale daemon locks causing 5s timeout delays.

Fixed in bd-ndyz (closed) via 5 sub-issues:
- bd-expt: Fast-fail socket checks (200ms timeout)
- bd-wgu4: Lock probe before RPC attempts
- bd-1mzt: Self-heal stale artifacts
- bd-vcg5: Panic recovery + socket cleanup
- bd-j7e2: RPC diagnostics (BD_RPC_DEBUG)

All fixes merged. Ready for v0.22.2 release.

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)


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.


Investigate jujutsu VCS as potential solution for conflict-free merging

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

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

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

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

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

bd init creates nested .beads directories

bd init sometimes creates .beads/.beads/ nested directories, which should never happen. This occurs fairly often and can cause confusion about which .beads directory is active. Need to add validation to detect if already inside a .beads directory and either error or use the parent .beads location.


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.


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)


Test graceful degradation when server unavailable

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

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

Success Metric: Zero functional difference when Agent Mail unavailable


bd-hv01: Brittle string comparison breaks with JSON field reordering

## Problem
deletion_tracking.go:125 uses string comparison to detect unchanged issues:

```go
if leftLine, existsInLeft := leftIndex[id]; existsInLeft && leftLine == baseLine {
    deletions = append(deletions, id)
}
```

This breaks if:
- JSON field order changes (legal in JSON)
- Timestamps updated by import/export
- Whitespace/formatting changes
- Floating point precision varies

## Example Failure
```json
// baseLine
{"id":"bd-1","priority":1,"status":"open"}
// leftLine (same data, different order)
{"id":"bd-1","status":"open","priority":1}
```
These are semantically identical but string comparison fails.

## Fix
Parse and compare JSON semantically:
```go
func jsonEquals(a, b string) bool {
    var objA, objB map[string]interface{}
    json.Unmarshal([]byte(a), &objA)
    json.Unmarshal([]byte(b), &objB)
    return reflect.DeepEqual(objA, objB)
}
```

## Files Affected
- cmd/bd/deletion_tracking.go:125
- cmd/bd/deletion_tracking.go:134-170 (buildIDToLineMap)


Update LINTING.md with current baseline

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


Consolidate check-health DB opens into single connection

The --check-health flag opens the database 3 separate times (once per quick check). Consolidate into a single DB open for better performance, especially on slower filesystems.

Replace Windows CI full test suite with smoke tests

## Problem

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

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

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

## Current State

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

## Solution: Smoke Tests Only

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

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

### Proposed CI Change

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

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

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

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

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


Improve CheckStaleness error handling

## Problem

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

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

## Edge Cases That Return False

1. **Invalid last_import_time format** (line 259-262)
2. **No JSONL file found** (line 267-277)
3. **JSONL stat fails** (line 279-282)

## Fix

Return errors for abnormal conditions:

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

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

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

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

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


Centralize BD_DEBUG logging into debug package

The codebase has 43 scattered instances of `if os.Getenv("BD_DEBUG") != ""` debug checks across 6 files. Centralize into a debug logging package.

Current locations:
- `cmd/bd/main.go` - 15 checks
- `cmd/bd/autoflush.go` - 6 checks
- `cmd/bd/nodb.go` - 4 checks
- `internal/rpc/server.go` - 2 checks
- `internal/rpc/client.go` - 5 checks
- `cmd/bd/daemon_autostart.go` - 11 checks

Target structure:
```
internal/debug/
└── debug.go
```

Benefits:
- Centralized debug logging
- Easier to add structured logging later
- Testable (can mock debug output)
- Consistent debug message format

Impact: Removes 43 scattered checks, improves code clarity


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 prime: AI context loading and Claude Code integration

Implement `bd prime` command and Claude Code hooks for context recovery. Hooks work with BOTH MCP server and CLI approaches - they solve the context memory problem (keeping bd workflow fresh after compaction) not the tool access problem (MCP vs CLI).


Create Go adapter library (optional)

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

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

File: pkg/agentmail/client.go

Note: Lower priority - can shell out to curl initially


Test parent issue


Benchmark git traffic reduction

Automated benchmark comparing git operations with/without Agent Mail.

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

File: tests/benchmarks/git_traffic.py

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

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

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

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


Add unit tests for parent resurrection

Test resurrection with deleted parent (should succeed), resurrection with never-existed parent (should fail gracefully), multi-level resurrection (bd-abc.1.2 with both parents missing). Verify tombstone creation and is_tombstone flag.


Document 3-clone ID non-determinism in collision resolution

Document the known behavior of 3+ way collision resolution where ID assignments may vary based on sync order, even though content always converges correctly.

Updates needed:
- Update bd-71107098 notes to mark 2-clone case as solved
- Document 3-clone ID non-determinism as known limitation
- Add explanation to ADVANCED.md or collision resolution docs
- Explain why this happens (pairwise hash comparison is deterministic, but multi-way ID allocation uses sync-order dependent counters)
- Clarify trade-offs: content convergence ✅ vs ID stability ❌

Key points to document:
- Hash-based resolution is pairwise deterministic
- Content always converges correctly (all issues present with correct data)
- Numeric ID assignments in 3+ way collisions depend on sync order
- This is acceptable for most use cases (content convergence is primary goal)
- Full determinism would require complex multi-way comparison


Add 'bd message send' command for Agent Mail messaging

Agent Mail server supports messaging between agents, but bd CLI only uses it for file reservations. Add commands for inter-agent messaging.

## Background
- Agent Mail server running at http://127.0.0.1:8765
- 12 workspaces configured across 3 channels (beads.dev, vc.dev, wyvern.dev)
- Current integration: file reservations only
- Gap: no way to send messages from bd CLI

## Proposed Commands

```bash
# Send message to another agent
bd message send <to-agent> <message> [options]
  --subject <subject>
  --thread-id <thread-id>     # Optional - group related messages
  --project-id <project>      # Defaults to BEADS_PROJECT_ID

# List inbox messages
bd message inbox [options]
  --limit <N>
  --unread-only

# Read specific message
bd message read <message-id>

# Mark message as acknowledged
bd message ack <message-id>
```

## Example Usage

```bash
# Send message to agent in same channel
bd message send cino-beads-stevey-macbook "Working on bd-z0yn, need your review" \
  --subject "Review request" \
  --thread-id bd-z0yn

# Check inbox
bd message inbox --unread-only

# Read and acknowledge
bd message read msg-abc123
bd message ack msg-abc123
```

## Design Notes
- Use same env vars (BEADS_AGENT_MAIL_URL, BEADS_AGENT_NAME, BEADS_PROJECT_ID)
- Graceful degradation if Agent Mail unavailable
- JSON output support for all commands
- Consider integrating with bd update/close (auto-notify on status changes)

## References
- Agent Mail README: ~/src/mcp_agent_mail/README.md
- Beads integration docs: docs/AGENT_MAIL.md

## Implementation Summary

Added four new commands to bd CLI for Agent Mail messaging:

1. `bd message send <to-agent> <message>` - Send messages to other agents
   - Flags: --subject, --thread-id, --importance, --ack-required
   - Supports markdown content
   - Thread conversations by issue ID

2. `bd message inbox` - List inbox messages
   - Flags: --limit, --unread-only, --urgent-only, --json
   - Shows subject, sender, age, importance
   - Highlights unread and ACK-required messages

3. `bd message read <message-id>` - Read and mark message as read
   - Automatically marks message as read
   - Shows message content

4. `bd message ack <message-id>` - Acknowledge a message
   - Marks message as acknowledged
   - Also marks as read if not already

## Implementation Details

- Uses JSON-RPC over HTTP to communicate with Agent Mail server
- Configuration via environment variables (BEADS_AGENT_MAIL_URL, BEADS_AGENT_NAME, BEADS_PROJECT_ID)
- Graceful error messages when Agent Mail not configured
- Full JSON output support for programmatic use
- Follows same patterns as existing bd commands

## Documentation

Updated:
- docs/AGENT_MAIL.md - Added "Messaging Commands" section with examples and best practices
- README.md - Added "Messaging (Agent Mail)" section in Usage

## Testing

- Compiles successfully
- Help output works correctly
- Ready for integration testing with Agent Mail server


Update python-agent example with Agent Mail integration

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

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

Auto-invoke 3-way merge for JSONL conflicts

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

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

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

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

**Reference:**
- beads-merge tool: https://github.com/neongreen/mono/tree/main/beads-merge
- Error occurs in post-merge hook during bd sync after git pull


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.


bd doctor: add SQLite integrity check (PRAGMA integrity_check)

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


Add "bd daemons" command for multi-daemon management

Add a new "bd daemons" command with subcommands to manage daemon processes across all beads repositories/worktrees. Should show all running daemons with metadata (version, workspace, uptime, last sync), allow stopping/restarting individual daemons, auto-clean stale processes, view logs, and show exclusive lock status.


bd-hv01: Deletion tracking production readiness

Epic to track all improvements and fixes needed to make the deletion tracking implementation ([deleted:bd-hv01]) production-ready.

The core 3-way merge algorithm is sound, but there are critical issues around atomicity, error handling, and edge cases that need to be addressed before this can be safely used in production.

Critical path (P1):
- Non-atomic snapshot operations
- Brittle JSON string comparison
- Silent partial deletion failures
- Race conditions in concurrent scenarios

Follow-up work (P2-P3):
- Test coverage for edge cases and multi-repo mode
- Performance optimizations
- Code refactoring and observability

Add cancellation and timeout tests

Add comprehensive tests for context cancellation and timeout behavior.

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

## Test Coverage Needed

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

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

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

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

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

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

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

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

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


bd message: Implement full message reading functionality

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

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

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

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

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


Remove unreachable RPC methods

Several RPC server and client methods are unreachable and should be removed:

Server methods (internal/rpc/server.go):
- `Server.GetLastImportTime` (line 2116)
- `Server.SetLastImportTime` (line 2123)
- `Server.findJSONLPath` (line 2255)

Client methods (internal/rpc/client.go):
- `Client.Import` (line 311) - RPC import not used (daemon uses autoimport)

Evidence:
```bash
go run golang.org/x/tools/cmd/deadcode@latest -test ./...
```

Impact: Removes ~80 LOC of unused RPC code


Add edge case tests for export metadata updates

## Current Coverage
TestExportUpdatesMetadata tests basic happy path only.

## Missing Test Cases

### 1. Multi-Repo Mode
- Export with multi-repo configuration
- Verify metadata updated for ALL JSONL files
- Critical gap (related to bd-ar2.2)

### 2. computeJSONLHash Failure
- JSONL file deleted/inaccessible after export
- Should log warning, not crash
- Verify behavior on next export

### 3. SetMetadata Failures
- Database write-protected
- Disk full
- Should log warnings, continue

### 4. os.Stat Failure
- JSONL file deleted after export, before stat
- Should handle gracefully (mtime just not updated)

### 5. Concurrent Exports
- Two daemon instances export simultaneously
- Verify metadata doesn't get corrupted
- Race condition test

### 6. Clock Skew
- System time goes backward between exports
- Verify mtime handling still works

### 7. Partial Export Failure
- Multi-repo mode: some exports succeed, some fail
- What metadata should be updated?

### 8. Large JSONL Files
- Performance test with large files (10k+ issues)
- Verify hash computation doesn't timeout

## Files
- cmd/bd/daemon_sync_test.go

## Implementation Priority
1. Multi-repo test (P1 - related to critical issue)
2. Failure handling tests (P2)
3. Performance/edge cases (P3)


Performance Testing Framework

Add comprehensive performance testing for beads focusing on optimization guidance and validating 10K+ database scale. Uses standard Go tooling, follows existing patterns, minimal complexity.

Components:
- Benchmark suite for critical operations at 10K-20K scale
- Fixture generator for realistic test data (epic hierarchies, cross-links)
- User diagnostics via bd doctor --perf
- Always-on profiling integration

Goals:
- Identify bottlenecks for optimization work
- Validate performance at 10K+ issue scale
- Enable users to collect diagnostics for bug reports
- Support both SQLite and JSONL import paths


Doctor should exclude merge artifacts from 'multiple JSONL' warning

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


Add unit tests for getLocalSyncBranch

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

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

Location: cmd/bd/autoimport_test.go


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)


Add Claude setup tip with dynamic priority

Add a predefined tip that suggests running `bd setup claude` when Claude Code is detected but not configured. This tip should have higher priority (shown more frequently) until the setup is complete.


Jira import/export integration

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

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

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

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

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


Update Metrics and Health Endpoints

Remove cache-related metrics from health/metrics endpoints


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


Test parent issue


Test issue 1


Investigate database pollution - issue count anomalies

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

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

Investigation findings:

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

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

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

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

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


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.


Extract duplicated metadata update code in daemon_sync.go

## Problem
The same 22-line metadata update block appears identically in both:
- createExportFunc (lines 309-328)
- createSyncFunc (lines 520-539)

This violates DRY principle and makes maintenance harder.

## Solution
Extract to helper function:

```go
// updateExportMetadata updates last_import_hash and related metadata after a successful export.
// This prevents "JSONL content has changed since last import" errors on subsequent exports (bd-ymj fix).
func updateExportMetadata(ctx context.Context, store storage.Storage, jsonlPath string, log daemonLogger) {
    currentHash, err := computeJSONLHash(jsonlPath)
    if err != nil {
        log.log("Warning: failed to compute JSONL hash for metadata update: %v", err)
        return
    }

    if err := store.SetMetadata(ctx, "last_import_hash", currentHash); err != nil {
        log.log("Warning: failed to update last_import_hash: %v", err)
    }

    exportTime := time.Now().Format(time.RFC3339)
    if err := store.SetMetadata(ctx, "last_import_time", exportTime); err != nil {
        log.log("Warning: failed to update last_import_time: %v", err)
    }

    // Store mtime for fast-path optimization
    if jsonlInfo, statErr := os.Stat(jsonlPath); statErr == nil {
        mtimeStr := fmt.Sprintf("%d", jsonlInfo.ModTime().Unix())
        if err := store.SetMetadata(ctx, "last_import_mtime", mtimeStr); err != nil {
            log.log("Warning: failed to update last_import_mtime: %v", err)
        }
    }
}
```

## Benefits
- Easier maintenance
- Single source of truth
- Consistent behavior


Extract hash ID generation functions to hash_ids.go

Move generateHashID, getNextChildNumber, GetNextChildID to hash_ids.go


bd doctor: export diagnostics history for debugging

Add ability to save doctor diagnostics to a file (e.g., diagnostics.json) for historical analysis and bug reporting. This would help track intermittent issues and provide context when filing bug reports. Could integrate with --perf output for comprehensive system snapshots.


Add bd migrate-tombstones command

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


Add unit tests for reset package

Comprehensive unit tests for internal/reset package.

## Test Cases

### ValidateState tests
- .beads/ exists → success
- .beads/ missing → appropriate error
- git dirty state detection

### CountImpact tests
- Empty .beads/ → zero counts
- With issues → correct count (open vs closed)
- With tombstones → correct count
- Returns HasUncommitted correctly

### Backup tests
- Creates backup with correct timestamp format
- Preserves all files and permissions
- Returns correct path
- Handles missing .beads/ gracefully
- Errors on pre-existing backup dir

### Git operation tests
- CheckGitState detects dirty, detached, not-a-repo
- GitRemoveBeads removes correct files
- GitCommitReset creates commit with message
- Operations skip gracefully when not in git repo

### Reset tests (with mocks/temp dirs)
- Soft reset removes files, calls init
- Hard reset includes git operations
- Dry run doesn't modify anything
- SkipInit flag prevents re-initialization
- Daemon killall is called
- Backup is created when requested

## Approach
- Can start with interface definitions (TDD style)
- Use testify for assertions
- Create temp directories for isolation
- Mock git operations where needed
- Test completion depends on implementation tasks

## File Location
`internal/reset/reset_test.go`

Test reservation expiration and renewal

Verify TTL-based reservation expiration works correctly.

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

File: tests/integration/test_reservation_ttl.py

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

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

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

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


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.


Add MCP functions for repair commands

Add repair commands to beads-mcp for agent access:
- beads_resolve_conflicts()
- beads_find_duplicates()
- beads_detect_pollution()
- beads_validate()

Files: integrations/beads-mcp/src/beads_mcp/server.py


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).


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


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

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

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

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

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

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

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

This is CRITICAL - main should never have breaking tests.


Audit Current Cache Usage

Understand exactly what code depends on the storage cache

Audit complete. See CACHE_AUDIT.md for full findings.

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


Optimize CLI test suite - eliminate redundant git init calls

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


Update documentation for hash IDs and aliases

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

## Files to Update

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Hash IDs are generated deterministically:

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

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

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

## Alias Conflict Resolution

When multiple clones assign same alias to different issues:

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

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

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

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

## Migration Steps

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

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

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

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

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

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

## FAQ

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

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

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

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

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

Fix TestListCommand duplicate dependency constraint violation


Implement `bd setup claude` command for Claude Code integration

Create a `bd setup claude` command that installs Claude Code integration files (slash commands and hooks). This is idempotent and safe to run multiple times.


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.


Extract daemon sync functions to daemon_sync.go


Test issue 2


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

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

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


bd jira sync command

Add a built-in bd command for Jira synchronization.

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

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

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

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

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


Pre-push hook and daemon export produce different JSONL

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

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

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

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

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

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

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


bd 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.


Prevent test pollution in production database

The bd-vxdr cleanup revealed test issues were created during manual testing in the production workspace (Nov 2-4, template feature development).

**Root cause:** Manual testing with `./bd create "Test issue"` pollutes the production .beads database.

**Prevention strategies:**
1. Use TEST_DB environment variable for manual testing
2. Add warning when creating issues with "Test" prefix
3. Improve developer docs about testing workflow
4. Consider adding `bd test-mode` command for isolated testing

**Implementation completed:**

1. ✅ Added warning when creating issues with "Test" prefix in production database
   - Shows yellow warning with ⚠ symbol
   - Suggests using BEADS_DB for isolated testing
   - Warning appears in create.go after title validation

2. ✅ Documented BEADS_DB testing workflow in AGENTS.md
   - Added "Testing Workflow" section in Development Guidelines
   - Includes manual testing examples with BEADS_DB
   - Includes automated testing examples with t.TempDir()
   - Clear warning about not polluting production database

3. ⚠ Decided against bd test-mode command
   - BEADS_DB already provides simple, flexible isolation
   - Additional command would add complexity without much benefit
   - Current approach follows Unix philosophy (env vars for config)

**Files modified:**
- cmd/bd/create.go - Added Test prefix warning
- AGENTS.md - Added Testing Workflow section

**Testing:**
- Verified warning appears when creating "Test" prefix issues
- Verified BEADS_DB isolation works correctly
- Built successfully with `go build`


Add bd alias command for manual alias control

Add command for users to manually view and reassign aliases.

## Command: bd alias

### Subcommands

#### 1. bd alias list
Show all alias mappings:
```bash
$ bd alias list
#1    → bd-af78e9a2  Fix authentication bug
#2    → bd-e5f6a7b8  Add logging to daemon
#42   → bd-1a2b3c4d  Investigate jujutsu integration
#100  → bd-9a8b7c6d  (reassigned after conflict)
```

#### 2. bd alias set <alias> <hash-id>
Manually assign alias to specific issue:
```bash
$ bd alias set 42 bd-1a2b3c4d
✓ Assigned alias #42 to bd-1a2b3c4d

$ bd alias set 1 bd-af78e9a2
✗ Error: Alias #1 already assigned to bd-e5f6a7b8
Use --force to override
```

#### 3. bd alias compact
Renumber all aliases to fill gaps:
```bash
$ bd alias compact [--dry-run]

Current aliases: #1, #2, #5, #7, #100, #101
After compacting: #1, #2, #3, #4, #5, #6

Renumbering:
  #5   → #3
  #7   → #4
  #100 → #5
  #101 → #6

Apply changes? [y/N]
```

#### 4. bd alias reset
Regenerate all aliases (sequential from 1):
```bash
$ bd alias reset [--sort-by=priority|created|id]

WARNING: This will reassign ALL aliases. Continue? [y/N]

Reassigning 150 issues by priority:
  bd-a1b2c3d4 → #1   (P0: Critical security bug)
  bd-e5f6a7b8 → #2   (P0: Data loss fix)
  bd-1a2b3c4d → #3   (P1: Jujutsu integration)
  ...
```

#### 5. bd alias find <hash-id>
Look up alias for hash ID:
```bash
$ bd alias find bd-af78e9a2
#1

$ bd alias find bd-nonexistent
✗ Error: Issue not found
```

## Use Cases

### 1. Keep Important Issues Low-Numbered
```bash
# After closing many P0 issues, compact to free low numbers
bd alias compact

# Or manually set
bd alias set 1 bd-<critical-bug-hash>
```

### 2. Consistent Aliases Across Clones
```bash
# After migration, coordinator assigns canonical aliases
bd alias reset --sort-by=id
git add .beads/aliases.jsonl
git commit -m "Canonical alias assignments"
git push

# Other clones pull and adopt
git pull
bd import  # Alias conflicts resolved automatically
```

### 3. Debug Alias Conflicts
```bash
# See which aliases were reassigned
bd alias list | grep "#100"
```

## Flags

### Global
- `--dry-run`: Preview changes without applying
- `--force`: Override existing alias assignments

### bd alias reset
- `--sort-by=priority`: Assign by priority (P0 first)
- `--sort-by=created`: Assign by creation time (oldest first)
- `--sort-by=id`: Assign by hash ID (lexicographic)

## Implementation

File: cmd/bd/alias.go
```go
func aliasListCmd() *cobra.Command {
    return &cobra.Command{
        Use:   "list",
        Short: "List all alias mappings",
        Run: func(cmd *cobra.Command, args []string) {
            aliases := storage.GetAllAliases()
            for _, a := range aliases {
                fmt.Printf("#%-4d → %s  %s\n",
                    a.Alias, a.IssueID, a.Title)
            }
        },
    }
}

func aliasSetCmd() *cobra.Command {
    return &cobra.Command{
        Use:   "set <alias> <hash-id>",
        Short: "Manually assign alias to issue",
        Args:  cobra.ExactArgs(2),
        Run: func(cmd *cobra.Command, args []string) {
            alias, _ := strconv.Atoi(args[0])
            hashID := args[1]

            force, _ := cmd.Flags().GetBool("force")
            if err := storage.SetAlias(alias, hashID, force); err != nil {
                fmt.Fprintf(os.Stderr, "Error: %v\n", err)
                os.Exit(1)
            }
            fmt.Printf("✓ Assigned alias #%d to %s\n", alias, hashID)
        },
    }
}
```

## Files to Create
- cmd/bd/alias.go

## Testing
- Test alias list output
- Test alias set with/without force
- Test alias compact removes gaps
- Test alias reset with different sort orders
- Test alias find lookup


Refactor create_test.go to use shared DB setup

Convert TestCreate_* functions to use test suites with shared database setup.

Example transformation:
- Before: 10 separate tests, each with newTestStore()
- After: 1 TestCreate() with 10 t.Run() subtests sharing one DB

Estimated speedup: 10x faster (1 DB setup instead of 10)


Comprehensive testing for separate branch workflow including unit tests, integration tests, and performance testing.

Tasks:
- Unit tests for worktree management
- Unit tests for config parsing
- Integration tests: create/update/close → beads branch
- Integration test: merge beads → main
- Integration test: protected branch scenario
- Integration test: network failure recovery
- Integration test: config change handling
- Manual testing guide
- Performance testing (worktree overhead)

Test scenarios: fresh setup, issue operations, merge workflow, protected branch, error handling, migration, multiple workspaces, sparse checkout

Estimated effort: 4-5 days

Completed comprehensive test coverage. Added 4 new integration tests: config change handling, multiple concurrent clones (3-way), performance testing (avg 77ms < 150ms target), and network failure recovery. All tests pass. Coverage includes fresh setup, issue ops, error handling, multiple workspaces, sparse checkout, config changes, network failures, and performance.


Run bd doctor at end of bd init to verify setup

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


Test dependency parent


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.


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.


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.


Optimize cmd/bd long-mode tests by switching to in-process testing

The long-mode CLI tests in cmd/bd are slow (1.4-4.4 seconds each) because they spawn full bd processes via exec.Command() for every operation.

Current approach:
- Each runBD() call spawns new bd process via exec.Command(testBD, args...)
- Each process initializes Go runtime, loads SQLite, parses CLI flags
- Tests run serially (create → update → show → close)
- Even with --no-daemon flag, there's significant process spawn overhead

Example timing from test run:
- TestCLI_PriorityFormats: 2.21s
- TestCLI_Show: 2.26s
- TestCLI_Ready: 2.29s
- TestCLI_Import: 4.42s

Optimization strategy:
1. Convert most tests to in-process testing (call bd functions directly)
2. Reuse test databases across related operations instead of fresh init each time
3. Keep a few exec.Command() tests that batch multiple operations to verify the CLI path works end-to-end

This should reduce test time from ~40s to ~5s for the affected tests.

Converted all CLI tests in cli_fast_test.go to use in-process testing via rootCmd.Execute(). Created runBDInProcess() helper that:
- Calls rootCmd.Execute() directly instead of spawning processes
- Uses mutex to serialize execution (rootCmd/viper not thread-safe)
- Properly cleans up global state (store, daemonClient)
- Returns only stdout to avoid JSON parsing issues with stderr warnings

Performance results:
- In-process tests: ~0.6s each (cached even faster)
- exec.Command tests: ~3.7s each
- Speedup: ~10x faster

Kept TestCLI_EndToEnd() that uses exec.Command for end-to-end validation of the actual binary.


Test Issue


Channel isolation test - beads

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


Integrate beads-merge tool by @neongreen

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

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

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

**Integration options**:

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

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

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

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

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

Next: Wait for response before proceeding with integration.

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

Next: Vendor beads-merge with full attribution


GH#245: Windows MCP subprocess timeout for git rev-parse

User reports git detection timing out on Windows in MCP server, but CLI works fine.

Path: C:\Users\chris\Documents\DEV_R\quarto-cli
Error: Git repository detection timed out after 5s
Works fine in CLI: `git rev-parse --show-toplevel` succeeds

Hypothesis: subprocess.run() with asyncio.to_thread() may have Windows-specific issues or the MCP runtime environment may not have proper PATH/git access.

Potential fixes:
1. Add subprocess shell=True on Windows
2. Increase timeout further for Windows
3. Add better error logging to capture subprocess stderr
4. Skip git resolution entirely on timeout and just use provided path


Remove unreachable RPC methods

Several RPC server and client methods are unreachable and should be removed:

Server methods (internal/rpc/server.go):
- `Server.GetLastImportTime` (line 2116)
- `Server.SetLastImportTime` (line 2123)
- `Server.findJSONLPath` (line 2255)

Client methods (internal/rpc/client.go):
- `Client.Import` (line 311) - RPC import not used (daemon uses autoimport)

Evidence:
```bash
go run golang.org/x/tools/cmd/deadcode@latest -test ./...
```

Impact: Removes ~80 LOC of unused RPC code


Add tests for Comments API (AddIssueComment, GetIssueComments)

Comments API currently has 0% coverage. Need tests for:
- AddIssueComment - adding comments to issues
- GetIssueComments - retrieving comments
- Comment ordering and pagination
- Edge cases (non-existent issues, empty comments)


Update GetStatistics to report tombstone count separately

Per bd-2m7 design: 'Should tombstones appear in bd stats? Recommendation: Yes, as separate counter: 5 deleted (tombstones)'

Currently GetStatistics counts tombstones in TotalIssues without distinguishing them.

Location: internal/storage/sqlite/events.go:114-121

Add to Statistics struct and query:
- DeletedIssues (tombstone count)
- Exclude tombstones from TotalIssues or document that it includes them


Issue 1


Create backup and restore procedures

Disaster recovery procedures for Agent Mail data.

Acceptance Criteria:
- Automated daily snapshots (GCP persistent disk)
- SQLite backup script
- Git repository backup
- Restore procedure documentation
- Test restore from backup

File: deployment/agent-mail/backup.sh


Make MCP compaction settings configurable (COMPACTION_THRESHOLD, PREVIEW_COUNT)

Currently COMPACTION_THRESHOLD (20) and PREVIEW_COUNT (5) are hardcoded constants at the module level. This prevents users from tuning context engineering behavior.

## Current State
```python
COMPACTION_THRESHOLD = 20  # Compact results with more than 20 issues
PREVIEW_COUNT = 5          # Show first 5 issues in preview
```

## Problems
1. No way for MCP clients to request different preview sizes
2. No way to disable compaction for debugging
3. No way to adapt to different context window sizes
4. Values are not documented in tool schema

## Recommended Solution
Add environment variables or MCP tool parameters:
- `BEADS_MCP_COMPACTION_THRESHOLD` env var (default: 20)
- `BEADS_MCP_PREVIEW_COUNT` env var (default: 5)
- Optional `compact_threshold` and `preview_size` parameters to list/ready tools

## Implementation Notes
- Keep current defaults for backward compatibility
- Read from environment at server initialization
- Document in CONTEXT_ENGINEERING.md
- Add tests verifying env var behavior


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.


Fix bd --version and bd completion to work without database


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


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


Test issue 2


Auto-detect scenarios and prompt users

Detect when user is in fork/contributor scenario and prompt with helpful suggestions. Check: git remote relationships, existing .beads config, repo ownership. Suggest appropriate wizard.


bd cleanup should also prune expired tombstones

## 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 shouldn't 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). Report results:

```
✓ Deleted 15 closed issue(s)
✓ Pruned 3 expired tombstone(s) (older than 30 days)
```

## Files to Modify

- `cmd/bd/cleanup.go` - Add call to pruneExpiredTombstones after deleteBatch
- May need to move pruneExpiredTombstones to shared location if not already accessible

## 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


Split internal/rpc/server.go into focused modules

The file `internal/rpc/server.go` is 2,273 lines with 50+ methods, making it difficult to navigate and prone to merge conflicts. Split into 8 focused files with clear responsibilities.

Current structure: Single 2,273-line file with:
- Connection handling
- Request routing
- All 40+ RPC method implementations
- Storage caching
- Health checks & metrics
- Cleanup loops

Target structure:
```
internal/rpc/
├── server.go          # Core server, connection handling (~300 lines)
├── methods_issue.go   # Issue operations (~400 lines)
├── methods_deps.go    # Dependency operations (~200 lines)
├── methods_labels.go  # Label operations (~150 lines)
├── methods_ready.go   # Ready work queries (~150 lines)
├── methods_compact.go # Compaction operations (~200 lines)
├── methods_comments.go # Comment operations (~150 lines)
├── storage_cache.go   # Storage caching logic (~300 lines)
└── health.go          # Health & metrics (~200 lines)
```

Migration strategy:
1. Create new files with appropriate methods
2. Keep `server.go` as main file with core server logic
3. Test incrementally after each file split
4. Final verification with full test suite


Unit tests for FileWatcher

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


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.


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


Test parent issue


Git history fallback assumes .beads is direct child of repo root

## Problem

`checkGitHistoryForDeletions` assumes the repo structure:

```go
repoRoot := filepath.Dir(beadsDir)  // Assumes .beads is in repo root
jsonlPath := filepath.Join(".beads", "beads.jsonl")
```

But `.beads` could be in a subdirectory (monorepo, nested project), and the actual JSONL filename could be different (configured via `metadata.json`).

## Location
`internal/importer/importer.go:865-869`

## Impact
- Git search will fail silently for repos with non-standard structure
- Monorepo users won't get deletion propagation

## Fix
1. Use `git rev-parse --show-toplevel` to find actual repo root
2. Compute relative path from repo root to JSONL
3. Or use `git -C <dir>` to run from beadsDir directly


Remove obsolete stale.go command (executor tables never implemented)


Use in-memory filesystem for test git operations

Use tmpfs/ramdisk for git operations in tests to reduce I/O overhead.

Options:
1. Mount /tmp as tmpfs in CI (GitHub Actions supports this)
2. Use Go's testing.TB.TempDir() which may already use tmpfs on some systems
3. Explicitly create ramdisk for tests on macOS

Expected savings: 20-30% reduction in git operation time


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


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.


CONFIG.md docs for sync.require_confirmation_on_mass_delete missing threshold detail

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


Test issue 1


Add multi-repo support to export metadata updates

## Problem
The bd-ymj fix only updates metadata for the main jsonlPath, but the codebase supports multi-repo mode where exports write to multiple JSONL files.

Other daemon_sync operations handle multi-repo correctly:
- Lines 509-518: Snapshots captured for all multi-repo paths
- Lines 578-587: Deletions applied for all multi-repo paths

But metadata updates are missing!

## Investigation Needed
Metadata is stored globally in database (`last_import_hash`, `last_import_mtime`), but multi-repo has per-repo JSONL files. Current schema may not support tracking multiple JSONL files.

Options:
1. Store metadata per-repo (new schema)
2. Store combined hash of all repos
3. Document that multi-repo doesn't need this metadata (why?)

## Solution (if needed)
```go
// After export
if multiRepoPaths := getMultiRepoJSONLPaths(); multiRepoPaths != nil {
    // Multi-repo mode: update metadata for each JSONL
    for _, path := range multiRepoPaths {
        updateExportMetadata(exportCtx, store, path, log)
    }
} else {
    // Single-repo mode: update metadata for main JSONL
    updateExportMetadata(exportCtx, store, jsonlPath, log)
}
```

- Possibly: internal/storage/sqlite/metadata.go (schema changes)

Document bd edit command and verify MCP exclusion

Follow-up from PR #152:
1. Add "bd edit" to AGENTS.md with "Humans only" note
2. Verify MCP server doesn't expose bd edit command
3. Consider adding test for command registration


Refactor duplicate JSONL-from-git parsing code

Both readFirstIssueFromGit() in init.go and importFromGit() in autoimport.go have similar code patterns for:
1. Running git show <ref>:<path>
2. Scanning the output with bufio.Scanner
3. Parsing JSON lines

Could be refactored to share a helper like:
- readJSONLFromGit(gitRef, path string) ([]byte, error)
- Or a streaming version: streamJSONLFromGit(gitRef, path string) (io.Reader, error)

Files:
- cmd/bd/autoimport.go:225-256 (importFromGit)
- cmd/bd/init.go:1212-1243 (readFirstIssueFromGit)

Priority is low since code duplication is minimal and both functions work correctly.

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


Optimize Memory backend GetIssueByExternalRef with index

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

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

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

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

Design contributor namespace isolation for beads pollution prevention

## Problem

When contributors work on beads-the-project using beads-the-tool, their personal work-tracking issues leak into PRs. The .beads/issues.jsonl is intentionally tracked (it's the project's issue database), but contributors' local issues pollute the diff.

This is a recursion problem unique to self-hosting projects.

## Possible Solutions to Explore

1. **Contributor namespaces** - Each contributor gets a private prefix (e.g., `bd-steve-xxxx`) that's gitignored or filtered
2. **Separate database** - Contributors use BEADS_DIR pointing elsewhere for personal tracking
3. **Issue ownership/visibility flags** - Mark issues as "local-only" vs "project"
4. **Prefix-based filtering** - Configure which prefixes are committed vs ignored

## Design Considerations

- Should be zero-friction for contributors (no manual setup)
- Must not break existing workflows
- Needs to work with sync/collaboration features
- Consider: what if a "personal" issue graduates to "project" issue?

## Expansion Needed

This is a placeholder. Needs detailed design exploration before implementation.


Run final validation and cleanup checks

Validation completed:
- LOC: 52,372 lines total
- Dead code: 4 functions in import_shared.go (tracked in bd-6fe4622f)
- Build: ✓ Successful

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
```


Design migration path from deletions.jsonl to tombstones

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

Fix autoimport tests for content-hash collision scoring

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

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

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

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

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

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

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

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

Missing test for IsExpiredTombstone edge cases

## Problem

The `IsExpiredTombstone()` function has several edge cases that aren't directly tested:

1. **Invalid DeletedAt timestamp** - Returns false (safety), but not tested
2. **ttl=0 fallback to DefaultTombstoneTTL** - Not tested directly
3. **Tombstone with empty DeletedAt** - Returns false, tested implicitly but not explicitly
4. **Clock skew grace period effect** - Not tested (would need time mocking)

## Current Test Coverage

The existing tests use `time.Now()` which makes them non-deterministic:
```go
DeletedAt: time.Now().Add(-24 * time.Hour).Format(time.RFC3339)
```

This works but doesn't test the expiration boundary precisely.

## Recommendation

Add explicit unit tests for `IsExpiredTombstone()`:

```go
func TestIsExpiredTombstone(t *testing.T) {
    tests := []struct {
        name      string
        status    string
        deletedAt string
        ttl       time.Duration
        expected  bool
    }{
        {"non-tombstone returns false", "open", "2024-01-01T00:00:00Z", 0, false},
        {"empty deleted_at returns false", "tombstone", "", 0, false},
        {"invalid timestamp returns false", "tombstone", "not-a-date", 0, false},
        {"within TTL returns false", "tombstone", time.Now().Add(-1*time.Hour).Format(time.RFC3339), 24*time.Hour, false},
        {"beyond TTL returns true", "tombstone", time.Now().Add(-48*time.Hour).Format(time.RFC3339), 24*time.Hour, true},
    }
    // ...
}
```

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.


Implement "bd daemons logs" subcommand

Add command to view daemon logs for a specific workspace. Requires daemon logging to file (may need separate issue for log infrastructure).
