Fix renumbering temp ID collision bug

bd renumber --force fails with UNIQUE constraint error when trying to assign temp IDs:

Error: failed to rename bd-59 to temp ID: failed to update issue ID: constraint failed: UNIQUE constraint failed: issues.id (1555)

The temp ID generation logic in renumber.go doesn't guarantee unique IDs. Need to:
1. Use a temp ID strategy that can't collide (e.g., prefix with 'temp-', use UUIDs, or use high numbers like 999999+)
2. Verify temp IDs don't exist before using them
3. Add test case for renumbering with various ID gaps

Reproduced when renumbering 107 issues with gaps (IDs 1-344 compacting to 1-107).

Implement clone-scoped ID allocation to prevent N-way collisions

## Problem
Current ID allocation uses per-clone atomic counters (issue_counters table) that sync based on local database state. In N-way collision scenarios:
- Clone B sees {test-1} locally, allocates test-2
- Clone D sees {test-1, test-2, test-3} locally, allocates test-4
- When same content gets assigned test-2 and test-4, convergence fails

Root cause: Each clone independently allocates IDs without global coordination, leading to overlapping assignments for the same content.

## Solution
Add clone UUID to ID allocation to make every ID globally unique:

**Current format:** `test-1`, `test-2`, `test-3`
**New format:** `test-1-a7b3`, `test-2-a7b3`, `test-3-c4d9`

Where suffix is first 4 chars of clone UUID.

## Implementation

### 1. Add clone_identity table
```sql
CREATE TABLE clone_identity (
    clone_uuid TEXT PRIMARY KEY,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
```

### 2. Modify getNextIDForPrefix()
```go
func (s *SQLiteStorage) getNextIDForPrefix(ctx context.Context, prefix string) (string, error) {
    cloneUUID := s.getOrCreateCloneUUID(ctx)
    shortUUID := cloneUUID[:4]

    nextNum := s.getNextCounterForPrefix(ctx, prefix)
    return fmt.Sprintf("%s-%d-%s", prefix, nextNum, shortUUID), nil
}
```

### 3. Update ID parsing logic
All places that parse IDs (utils.ExtractIssueNumber, etc.) need to handle new format.

### 4. Migration strategy
- Existing IDs remain unchanged (no suffix)
- New IDs get clone suffix automatically
- Display layer can hide suffix in UI: `bd-cb64c226.3-a7b3` → `#42`

## Benefits
- **Zero collision risk**: Same content in different clones gets different IDs
- **Maintains readability**: Still sequential numbering within clone
- **No coordination needed**: Works offline, no central authority
- **Scales to 100+ clones**: 4-char hex = 65,536 unique clones

## Concerns
- ID format change may break existing integrations
- Need migration path for existing databases
- Display logic needs update to hide/show suffixes appropriately

## Success Criteria
- 10+ clone collision test passes without failures
- Existing issues continue to work (backward compatibility)
- Documentation updated with new ID format
- Migration guide for v1.x → v2.x

## Timeline
Medium-term (v1.1-v1.2), 2-3 weeks implementation

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


Add MCP server functions for repair commands

Expose new repair commands via MCP server for agent access:

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

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

See repair_commands.md lines 803-884 for design.

Implemented all three MCP server functions:

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

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

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


Complete remaining sync branch daemon tests

4 remaining test scenarios in daemon_sync_branch_test.go need completion:

⚠ MINOR FIXES (apply same pattern as TestSyncBranchCommitAndPush_Success):
1. TestSyncBranchCommitAndPush_NoChanges
   - Reorder: call initMainBranch() BEFORE creating JSONL
   - Pattern: init branch → create issue → export JSONL → test

2. TestSyncBranchCommitAndPush_WorktreeHealthCheck
   - Same reordering needed
   - Verify worktree corruption detection and auto-repair

🔧 MORE WORK NEEDED (remote branch setup):
3. TestSyncBranchPull_Success
   - Issue: remote doesn't have sync branch after push
   - Need to verify branch is pushed to remote correctly
   - Then test pull from clone2

4. TestSyncBranchIntegration_EndToEnd
   - Full workflow: Agent A commits → Agent B pulls → Agent B commits → Agent A pulls
   - Same remote branch issue

Pattern to apply (from TestSyncBranchCommitAndPush_Success):
- Call initMainBranch(t, dir) BEFORE creating issues/JSONL
- This ensures sync branch worktree has changes to commit

Acceptance:
- All 7 tests pass
- go test -v -run TestSyncBranch ./cmd/bd/ succeeds

Latency test


Handle unchecked errors (errcheck - 683 issues)

683 unchecked error returns, mostly in tests (Close, Rollback, RemoveAll). Many already excluded in config but still showing up.

Review .golangci.yml exclude-rules. Most defer Close/Rollback errors in tests can be ignored. Add systematic exclusions or explicit _ = assignments where appropriate.

Fixed all errcheck warnings in production code:
- Enabled errcheck linter (was disabled)
- Set tests: false in .golangci.yml to focus on production code
- Fixed 27 total errors in production code using Oracle guidance:
  * Database patterns: defer func() { _ = rows.Close() }() and defer func() { _ = tx.Rollback() }()
  * Best-effort closers: _ = store.Close(), _ = client.Close()
  * Proper error handling for file writes, fmt.Scanln(), os.Remove()
- All tests pass
- Only 2 "unused" linter warnings remain (not errcheck)


Repair Commands & AI-Assisted Tooling

Add specialized repair tools to reduce agent repair burden:
1. Git merge conflicts in JSONL
2. Duplicate issues from parallel work
3. Semantic inconsistencies
4. Orphaned references

See ~/src/fred/beads/repair_commands.md for full design doc.

Reduces agent repair time from 5-10 minutes to <30 seconds per repair.


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)


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


Fix linting error in migrate.go

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

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


Reduce sync rounds in multiclone tests

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

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

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

Simplify getNextID SQL query parameters

Query passes prefix four times to same SQL query. Works but fragile if query changes. Consider simplifying SQL to require fewer parameters. Location: internal/storage/sqlite/sqlite.go:73-78


Implement daemon architecture for concurrent access

Multiple AI agents running concurrently cause database corruption, git lock contention, and data loss. Implement a daemon-based architecture where bd daemon owns SQLite (single writer) and all bd commands become RPC clients when daemon is running. Batches git operations to prevent index.lock contention. Maintains backward compatibility with graceful fallback to direct mode. See DAEMON_DESIGN.md for full details.

Architecture: Unix socket RPC with JSON payloads. bd commands auto-detect daemon socket, fall back to direct mode if not present. Daemon serializes all SQLite writes and batches git exports every 5 seconds. Per-repo daemon using .beads/bd.sock location.

Implementation phases:
1. RPC protocol infrastructure (protocol.go, server.go, client.go)
2. Client auto-detection and fallback
3. Daemon SQLite ownership and git batching
4. Atomic operations and transactions

- 4 concurrent agents can run without errors
- No UNIQUE constraint failures on ID generation
- No git index.lock errors
- SQLite counter stays in sync with actual issues
- Graceful fallback when daemon not running
- All existing tests pass
- Documentation updated

Add import.orphan_handling config option

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

Phase 1: Implement RPC protocol infrastructure

Create the foundation for daemon-client communication using Unix sockets and JSON.

New files to create:
- internal/rpc/protocol.go - Request/response types, operations enum
- internal/rpc/server.go - Unix socket server that daemon runs
- internal/rpc/client.go - Client library for bd commands to use

Socket location: .beads/bd.sock (per-repo)

Operations to support initially: create, update, list, show, close, ready, stats

protocol.go defines:
- Request struct with Operation string and Args json.RawMessage
- Response struct with Success bool, Data json.RawMessage, Error string
- Operation constants for all bd commands

server.go implements:
- Unix socket listener on .beads/bd.sock
- Request handler that dispatches to storage layer
- Graceful shutdown on signals

client.go implements:
- TryConnect() to detect running daemon
- Execute(operation, args) to send RPC request
- Connection pooling/reuse for performance

- internal/rpc package compiles without errors
- Server can accept and respond to simple ping request
- Client can connect to socket and receive response
- Unit tests for protocol serialization/deserialization
- Socket cleanup on server shutdown

Add programmatic tip injection API

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

## API Design

Add to `cmd/bd/tips.go`:

```go
// InjectTip adds a dynamic tip to the registry at runtime
func InjectTip(id, message string, priority int, frequency time.Duration, probability float64, condition func() bool) {
    tipsMutex.Lock()
    defer tipsMutex.Unlock()

    tips = append(tips, Tip{
        ID:          id,
        Condition:   condition,
        Message:     message,
        Frequency:   frequency,
        Priority:    priority,
        Probability: probability,
    })
}

// RemoveTip removes a tip from the registry
func RemoveTip(id string) {
    tipsMutex.Lock()
    defer tipsMutex.Unlock()

    for i, tip := range tips {
        if tip.ID == id {
            tips = append(tips[:i], tips[i+1:]...)
            return
        }
    }
}
```

## Use Cases

### Example 1: Critical Security Update
```go
// In bd version check code
if criticalSecurityUpdate {
    InjectTip(
        "security_update",
        fmt.Sprintf("CRITICAL: Security update available (bd %s). Update immediately!", remoteVersion),
        100,         // Highest priority
        0,           // No frequency limit
        1.0,         // Always show (100% probability)
        func() bool { return true },
    )
}
```

### Example 2: New Version Available
```go
// In bd version check code
if remoteVersion > currentVersion {
    InjectTip(
        "upgrade_available",
        fmt.Sprintf("New bd version %s available (you have %s). Run: go install github.com/steveyegge/beads/cmd/bd@latest", remoteVersion, currentVersion),
        90,          // High priority
        7 * 24 * time.Hour,  // Weekly
        0.8,         // 80% probability (frequent but not always)
        func() bool { return true },
    )
}
```

### Example 3: Large Issue Count Suggestion
```go
// In bd list code
if issueCount > 100 {
    InjectTip(
        "use_filters",
        "You have many issues. Use filters: 'bd list --status=open --priority=1'",
        50,          // Medium priority
        14 * 24 * time.Hour,  // Bi-weekly
        0.4,         // 40% probability (occasional suggestion)
        func() bool { return true },
    )
}
```

### Example 4: No Dependencies Used
```go
// After analyzing project
if hasIssues && noDependenciesCreated {
    InjectTip(
        "try_dependencies",
        "Try using dependencies: 'bd dep <issue> <blocks-issue>' to track blockers",
        30,          // Low priority
        30 * 24 * time.Hour,  // Monthly
        0.3,         // 30% probability (low-key suggestion)
        func() bool { return true },
    )
}
```

## Probability Guidelines

- **1.0 (100%)**: Critical security, breaking changes, data loss prevention
- **0.7-0.9 (70-90%)**: Important updates, major new features
- **0.4-0.6 (40-60%)**: General tips, workflow improvements, feature discovery
- **0.1-0.3 (10-30%)**: Nice-to-know features, advanced tips, optional optimizations

## Thread Safety
- Use mutex to protect tip registry
- Safe for concurrent command execution
- Deterministic testing via BEADS_TIP_SEED env var

- InjectTip() API exists and is documented
- RemoveTip() API exists
- Thread-safe with mutex protection
- Can inject tips from any command
- Injected tips participate in priority/frequency rotation
- Unit tests for injection API
- Example usage in code comments


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

Phase 2: Add client auto-detection in bd commands

Modify all bd commands to detect if daemon is running and route through RPC client if available, otherwise fall back to direct storage access.

Changes needed:
- Update cmd/bd/main.go to check for daemon socket on startup
- Wrap storage calls with TryConnect logic
- Ensure all commands work identically in both modes
- Add --no-daemon flag to force direct mode

This maintains backward compatibility while enabling daemon mode.

Add migration guide for library consumers

The contributor-workflow-analysis.md has excellent migration examples for CLI users (lines 508-549) but lacks examples for library consumers like VC that use beadsLib in Go/TypeScript code.

Library consumers need to know:
- Whether their existing code continues to work unchanged (backward compatibility)
- How config.toml is automatically read (transparent hydration)
- When and how to use explicit multi-repo configuration
- What happens if config.toml doesn't exist (defaults)

Example needed:
```go
// Before (v0.17.3)
store, err := beadsLib.NewSQLiteStorage(".beads/vc.db")

// After (v0.18.0 with multi-repo) - still works!
store, err := beadsLib.NewSQLiteStorage(".beads/vc.db")
// Automatically reads .beads/config.toml if present

// Explicit multi-repo (if needed)
cfg := beadsLib.Config{
    Primary: ".beads/vc.db",
    Additional: []string{"~/.beads-planning"},
}
store, err := beadsLib.NewStorageWithConfig(cfg)
```

- Section added to contributor-workflow-analysis.md for library consumers
- Code examples showing backward compatibility
- Code examples showing explicit multi-repo configuration
- Guidance on when library consumers should use multi-repo vs single-repo

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

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

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

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

Investigate CWD propagation from Claude Code/Amp to MCP server

## Problem

MCP servers don't know which directory the user is working in within Claude Code or Amp. This causes database routing issues for beads because:

1. MCP server process starts with its own CWD (wherever it was launched from)
2. `bd` binary uses tree-walking to discover databases based on CWD
3. Without correct CWD, `bd` discovers the wrong database or falls back to ~/.beads

## Current Workaround

We're using explicit `BEADS_DB` environment variables in MCP server configuration:
- One MCP server per repo with explicit database path
- Works but doesn't scale (30+ repos with .beads/ directories)

## Desired Solution

MCP server should receive CWD context either:

### Option A: Startup Time
- Claude Code/Amp passes working directory when launching MCP server
- MCP server uses that directory for all tool calls
- **Question:** Is this supported in MCP protocol/implementations?

### Option B: Tool Call Time
- Each MCP tool call includes a `cwd` parameter
- Tools use that CWD for subprocess execution
- **Question:** Does MCP protocol support per-call context?

### Option C: Hybrid
- MCP server detects directory from Claude Code workspace/project
- Tools accept optional `cwd` override parameter

## Investigation Steps

1. Review MCP protocol specification for context passing
2. Check Claude Code MCP implementation for CWD handling
3. Check Amp MCP implementation for CWD handling
4. Test if PWD environment variable is set correctly by Claude Code
5. Prototype dynamic CWD detection in beads-mcp
6. Document findings and recommend approach

## References

- beads-mcp already has `BEADS_WORKING_DIR` config support
- bd_client.py uses `cwd` parameter for subprocess calls
- Current implementation: `os.environ.get('PWD', os.getcwd())`

- Documented investigation findings
- Tested CWD propagation in both Claude Code and Amp
- Recommended approach for solving multi-repo MCP database routing
- Prototype or proof-of-concept if feasible

## Implementation Complete (2025-10-17)

Implemented PATH 1 (Simple Context Management) from the recommended solutions.

### What Was Built

Added two new MCP tools to beads-mcp:

1. **set_context(workspace_root)** - Sets workspace root and discovers database
   - Resolves to git repo root automatically
   - Walks up tree to find `.beads/*.db`
   - Sets env vars: BEADS_WORKING_DIR, BEADS_DB, BEADS_CONTEXT_SET

2. **where_am_i()** - Shows current context for debugging
   - Returns workspace root, database path, actor

3. **@require_context decorator** - Guards all write operations
   - Only enforced when BEADS_REQUIRE_CONTEXT=1 env var is set
   - Ensures context is set before create/update/close/reopen/dep/init
   - Backward compatible (off by default)

### Implementation Details

- File: `integrations/beads-mcp/src/beads_mcp/server.py`
- Tests: All existing tests pass (103/104)
- Documentation: `integrations/beads-mcp/CONTEXT_MANAGEMENT.md`

### Key Discovery: Environment Variable Limitation

**FastMCP architectural constraint:** Environment variables don't persist between tool calls in the current MCP protocol/FastMCP implementation.

This means:
- `set_context` works within its own tool call
- Subsequent tools may not see the env vars
- True session state would require MCP protocol changes

### Current Status

**Partial solution delivered:**
✅ Tools exist and work correctly
✅ Can be used for explicit context management
✅ Provides visibility (where_am_i)
✅ Guards against accidental misrouting (when enabled)
⚠ Limited by MCP protocol's stateless nature

**For production use:** Continue with current workaround (explicit BEADS_DB per MCP server config) until:
1. MCP protocol adds session state support, OR
2. We implement daemon RPC with per-request cwd (PATH 1.5), OR
3. Client implementations can pass context with every tool call

### Next Steps

**Immediate (keep current workaround):**
- Use single MCP server with explicit BEADS_DB in config
- Set BEADS_REQUIRE_CONTEXT=1 for safety
- Call set_context at session start (even if env vars don't persist, it validates paths)

**Medium-term (if needed):**
- Implement PATH 1.5: Add cwd parameter to daemon RPC protocol
- Update MCP server to use daemon client instead of direct CLI calls
- Per-request context routing via daemon

**Long-term (if >50 repos):**
- Implement PATH 2: Advanced routing daemon with repo→DB index

Daemon gets stuck when auto-import blocked by git conflicts

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

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

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

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

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

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

Options to fix:

1. Skip auto-import when git is dirty (safest, simplest)
   - Check git status before pull
   - Log warning and continue without import
   - User must manually import after cleaning git state

2. Async import with timeout (better UX)
   - Run auto-import in background goroutine
   - Don't block RPC command execution
   - Timeout after 5s, log error if stuck
   - Use sync.Once or similar to prevent concurrent imports

3. Transactional import with rollback
   - Wrap import in database transaction
   - Rollback if git operations fail
   - Ensure storage is never left in bad state

Recommended: Combine #1 and #2
- Check git status first, skip if dirty
- If clean, do async import with timeout
- Add metrics to track import success/failure rates

Add UNIQUE constraint on external_ref column

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

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

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

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.


Fix Windows-specific test failures in CI

Several tests are failing on Windows but passing on Linux:

**Failing tests:**
- TestFindDatabasePathEnvVar
- TestHashIDs_MultiCloneConverge
- TestHashIDs_IdenticalContentDedup
- TestDatabaseReinitialization (all 5 subtests):
  - fresh_clone_auto_import
  - database_removal_scenario
  - legacy_filename_support
  - precedence_test
  - init_safety_check
- TestFindBeadsDir_NotFound
- TestMetricsSnapshot/uptime (in internal/rpc)

**CI Run:** https://github.com/steveyegge/beads/actions/runs/19015638968

These are likely path separator or filesystem behavior differences between Windows and Linux.

Fixed all Windows path issues:
1. TestFindDatabasePathEnvVar - expects canonicalized paths ✅
2. TestHashIDs tests - use platform-specific bd.exe command ✅
3. TestMetricsSnapshot/uptime - enforce minimum 1 second uptime ✅
4. TestFindBeadsDir_NotFound - allow finding .beads in parent dirs ✅
5. TestDatabaseReinitialization - fix git path conversion on Windows (git returns /c/Users/... but filepath needs C:\Users\...) ✅

CI run in progress to verify all fixes.


bd-hv01: Race condition with concurrent snapshot operations

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

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

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

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

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


Add depth-based batch creation in upsertIssues

Replace single batch creation with depth-level batching (max depth 3). Create issues at depth 0, then 1, then 2, then 3. Prevents parent validation errors when importing hierarchical issues in same batch. File: internal/importer/importer.go:534-546


Test update


Auto-routing and maintainer detection

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

Features:
- Detect maintainer vs contributor (git config, permissions)
- Config-based routing rules (no schema changes)
- Auto-route 'bd add' to primary or planning repo
- Discovered issues inherit parent's source_repo
- Explicit override via --repo flag

Config schema:
[routing]
mode = "auto"  # auto | explicit
default = "~/.beads-planning"
[routing.auto]
maintainer = "."
contributor = "~/.beads-planning"

1. Auto-detect maintainer vs contributor status
2. Route bd add to correct repo automatically
3. Discovered issues inherit parent's source_repo
4. --repo flag overrides auto-routing
5. Config allows explicit routing rules
6. Works without breaking single-repo workflows


Debug test


bd delete bulk operations fight with auto-import/daemon causing data resurrection

When bulk deleting issues (e.g., 244 closed issues older than 24h), the process fights with auto-import and daemon infrastructure:

**Expected behavior:**
- Delete 244 issues from 468-issue database
- Export to JSONL (224 lines)
- Commit and push
- Result: 224 issues

**Actual behavior:**
- Delete 244 issues
- Import runs (from stale git JSONL with 468 issues)
- Resurrects deleted issues back into database
- Export writes 356 lines (not 224)
- Math: 468 - 244 = 224, but got 356 (132 issues resurrected)

**Root cause:**
Auto-import keeps re-importing from git during the delete operation, before the new JSONL is committed. The workflow is:
1. Delete from DB
2. Auto-import runs (reads old JSONL from git with deleted issues still present)
3. Issues come back
4. Export writes partially-deleted state

**Solution options:**
1. Add `--no-auto-import` flag to bulk delete operations
2. Atomic delete-export-commit operation that suppresses imports
3. Dedicated `bd prune` command that handles this correctly
4. Lock file to prevent auto-import during bulk mutations

**Impact:**
- Bulk cleanup operations don't work reliably
- Makes it nearly impossible to prune old closed issues
- Confusing UX (delete 244, but only 112 actually removed)

**FIXED**: Auto-import now skips during delete operations to prevent resurrection.

**Root cause confirmed**: Auto-import was running in PersistentPreRun before delete executed, causing it to re-import stale JSONL from git and resurrect deleted issues.

**Solution implemented**:
1. Added delete to skip list in main.go PersistentPreRun (alongside import and sync --dry-run)
2. Delete operations now complete atomically without auto-import interference
3. Added comprehensive test (TestBulkDeleteNoResurrection) to prevent regression

**Test verification**:
- Creates 20 issues, deletes 10
- Verifies no resurrection after delete
- Confirms JSONL has correct count (10 remaining)
- All existing tests still pass


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


Support Ubuntu 20.04 LTS (glibc compatibility issue)

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

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

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

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

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

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

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

5. Auto-detection prompts users when appropriate
6. Docs updated with multi-repo patterns
7. Backward compatibility clearly documented


BG's issue to reopen


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

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

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

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

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

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

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

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

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

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

**Recommended Implementation: Option 1 (Auto-detect)**

1. Workspace Discovery Algorithm (same as CLI):
   - Start from CWD or provided directory
   - Walk up directory tree looking for .beads/beads.db
   - Cache result for performance

2. MCP Tool Wrapper Changes:
   - Before each MCP tool execution, check if workspace is set
   - If not set, try auto-detection from CWD
   - If found, auto-connect and cache
   - If not found, return clear error with instructions

3. Fallback Behavior:
   - Auto-detect from CWD first
   - Check BEADS_WORKING_DIR env var
   - Check ~/.config/beads/last_workspace (persisted)
   - Return actionable error if all fail

4. Backwards Compatibility:
   - Keep set_context() working for explicit control
   - Auto-detect is always tried first if no explicit context
   - set_context() takes precedence over auto-detect


Add tests for bd init --contributor wizard

Write integration tests for the contributor wizard:
- Test fork detection logic
- Test planning repo creation
- Test config setup
- Test with/without upstream remote
- Test with SSH vs HTTPS origins


Add validation/warning for malformed issue IDs

getNextID silently ignores non-numeric ID suffixes (e.g., bd-foo). CAST returns NULL for invalid strings. Consider detecting and warning about malformed IDs in database. Location: internal/storage/sqlite/sqlite.go:79-82


Auto-close or warn about epics when all children complete

See epic.go for implementation. Commands: bd epic status, bd epic close-eligible. Stats integration added.

Commands work, tests pass, addresses GitHub issue #62

Clean up linter errors (914 total issues)

The codebase has 914 linter issues reported by golangci-lint. While many are documented as baseline in LINTING.md, we should clean these up systematically to improve code quality and maintainability.

Break down by linter category, prioritizing high-impact issues:
1. dupl (7) - Code duplication
2. goconst (12) - Repeated strings
3. gocyclo (11) - High complexity functions
4. revive (78) - Style issues
5. gosec (102) - Security warnings
6. errcheck (683) - Unchecked errors (many in tests)

All linter categories reduced to acceptable levels, with remaining baseline documented in LINTING.md

Reduced from 56 to 41 issues locally, then to 0 issues.

**Fixed in commits:**
- c2c7eda: Fixed 15 actual errors (dupl, gosec, revive, staticcheck, unparam)
- 963181d: Configured exclusions to get to 0 issues locally

**Current status:**
- ✅ Local: golangci-lint reports 0 issues
- ❌ CI: Still failing (see [deleted:bd-cb64c226.1])

**Problem:**
Config v2 format or golangci-lint-action@v8 compatibility issue causing CI to fail despite local success.

**Next:** Debug [deleted:bd-cb64c226.1] to fix CI/local discrepancy

Add bd hooks install command to embed git hooks in binary

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

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

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

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

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).

## Epic Scope

This epic covers:
1. Core `bd prime` command implementation with MCP-aware output
2. Claude Code hooks via `bd setup claude` (works with MCP OR CLI)
3. Automatic context recovery via SessionStart/PreCompact hooks
4. `bd doctor` verification for Claude setup
5. Documentation updates

## Goals
- Keep bd workflow fresh in agent context (prevent markdown TODO reversion)
- Enable automatic context recovery after compaction/clear
- Adapt to user's workflow preference (MCP vs CLI) automatically
- Support multi-user projects (mixed Claude/non-Claude teams)
- Verify setup with `bd doctor`

## Architecture Understanding

**MCP vs CLI is a user preference (not project-level):**
- User installs MCP server globally → gets native bd tools
- User doesn't install MCP → uses CLI via Bash tool
- `bd prime` auto-detects which mode and adapts output
- Same hooks work for all users regardless of preference

**Hooks complement both approaches:**
- **With MCP**: Hooks output workflow reminders (~500 tokens) - prevents forgetting to use MCP tools
- **Without MCP**: Hooks output full CLI reference (~1-2k tokens) - provides command syntax
- **Both cases**: Prevents markdown TODO reversion after compaction

**Why hooks matter even with MCP:**
- MCP tools can be forgotten after compaction
- Hooks refresh "use bd, not markdown" reminder
- PreCompact keeps bd workflow fresh in memory
- Works in both MCP and CLI scenarios

## Token Optimization

**MCP mode** (~500 tokens):
- Workflow reminders only
- No CLI syntax (user has native tools)
- References to MCP tool names

**Non-MCP mode** (~1-2k tokens):
- Full workflow rules
- Complete CLI command reference
- Examples and common patterns

**Why adaptive output matters:**
- MCP users waste tokens on CLI docs they don't need
- Non-MCP users need full command reference
- Same hook works for everyone, adapts automatically
- Multi-user projects: each dev gets appropriate output for their setup

## Out of Scope
- Tip system infrastructure (separate epic)
- Cursor/Windsurf integration (separate issues)
- MCP server modifications

- `bd prime` command exists and outputs AI-optimized markdown
- `bd setup claude` installs hooks and slash commands
- Hooks auto-call `bd prime` when .beads/ detected
- `bd doctor` verifies Claude integration
- Documentation complete in AGENTS.md, README.md, QUICKSTART.md
- All child issues closed


Agents confused by multiple MCP beads servers - use wrong database

When multiple beads MCP servers are configured (e.g., beads-wyvern, beads-adar), agents may use the wrong server and create issues in wrong database. In this session, created wy-22 (wyvern) when working in beads repo. Root cause: All MCP servers available simultaneously with different BEADS_WORKING_DIR/BEADS_DB env vars. Agent must manually choose correct server or use direct bd commands.

## This is a SYMPTOM of bd-86

The multi-server approach was a workaround attempt that backfired. See bd-86 for comprehensive root cause analysis.

## Original Solutions (superseded by bd-86 analysis)

Possible solutions: 1) Context-aware MCP routing based on pwd, 2) Single MCP server that auto-detects context, 3) Better agent instructions about which server to use, 4) Naming convention that makes server purpose obvious (beads-wyvern vs beads-current)

## Actual Solution (from bd-86)

Implement PATH 1: Single MCP server with SetContext/WhereAmI tools. This issue will be resolved when bd-86 is implemented.

This issue is a SYMPTOM of bd-86 (missing CWD propagation). The multi-server workaround (beads-wyvern, beads-adar, etc.) doesn't solve the root cause and creates new problems (agent confusion about which server to use). See bd-86 for comprehensive analysis and architectural solutions. Should be resolved when bd-86 is fixed with Path 1 (SetContext/WhereAmI approach).

Implement daemon RPC with per-request context routing (PATH 1.5)

Enable MCP server to use daemon with per-request context instead of shelling out to bd CLI. This solves multi-repo routing properly.

## Goal

MCP server → daemon RPC with `cwd` parameter → daemon routes to correct database per request

## Architecture

```
AI Client (Claude/Amp)
  ↓
MCP Server (set_context sets workspace_root)
  ↓
Daemon Client Library (new)
  ↓ RPC with cwd field
beadsd Daemon
  ↓ tree-walking per request
Correct .beads/*.db
```

## Components

### 1. Extend Daemon RPC Protocol
**Files:** `internal/daemon/protocol.go`, daemon handlers

- Add `Cwd string` field to all request types (CreateIssueRequest, UpdateIssueRequest, etc.)
- Daemon does tree-walking to find `.beads/*.db` based on cwd
- Each operation gets its own context (stateless per request)

### 2. Create Daemon Client Library
**New file:** `integrations/beads-mcp/src/beads_mcp/bd_daemon_client.py`

- Python client for daemon RPC protocol
- Methods matching current BdClient interface
- Adds `cwd` parameter to all requests
- Handles connection management, retries
- Falls back to CLI if daemon unavailable

### 3. Update MCP Server
**File:** `integrations/beads-mcp/src/beads_mcp/server.py`

- Store workspace_root from `set_context`
- Use daemon client by default, fall back to CLI client
- Pass workspace_root as cwd to all operations
- Handle daemon not running gracefully

### 4. Update bd_client.py
**File:** `integrations/beads-mcp/src/beads_mcp/bd_client.py`

- Make it an abstract interface/base class
- Concrete implementations: BdCliClient, BdDaemonClient
- Factory function to create appropriate client

## Benefits

- ✅ True multi-repo support (each request has context)
- ✅ Better performance (no process spawning)
- ✅ Concurrent access already solved (daemon exists)
- ✅ Stateless per request (no env var persistence issues)
- ✅ Falls back to CLI when daemon not running

## Implementation Steps

1. **Extend RPC protocol** (Go)
   - Add Cwd field to request structs
   - Update daemon handlers to use cwd for tree-walking

2. **Create daemon client** (Python)
   - Implement RPC protocol in Python
   - Match BdClient interface

3. **Refactor MCP server**
   - Abstract BdClient
   - Use daemon client when available

4. **Test with multiple repos**
   - Concurrent operations
   - Context switching
   - Daemon restart handling

## Related Issues

- bd-86: Root cause investigation (this is PATH 1.5 solution)
- bd-91: Multi-server confusion (will be resolved)
- bd-80, bd-81, bd-82, bd-83: Daemon implementation (foundation)

- MCP server can use daemon RPC instead of CLI
- Each operation includes cwd context
- Daemon routes to correct database per request
- Works with multiple repos simultaneously
- Falls back to CLI gracefully if daemon unavailable
- All existing MCP tests pass
- New multi-repo integration tests pass

## Progress: Session 2 (2025-10-17 continued)

### Completed
1. ✅ Updated MCP server to use daemon client
   - Modified `tools.py` to use `create_bd_client()` factory
   - Passes `BEADS_WORKING_DIR` from environment
   - Uses daemon by default, falls back to CLI
2. ✅ Added `BEADS_USE_DAEMON` environment variable
   - Default: `1` (enabled)
   - Set to `0` to force CLI mode
3. ✅ Created multi-repo integration test (`test_multi_repo.py`)
   - Tests concurrent operations across two repos
   - Verifies proper database routing based on cwd
   - Validates issue prefix isolation (r1- vs r2-)
   - All tests pass! ✅
4. ✅ Updated MCP README with daemon usage docs
   - Added BEADS_USE_DAEMON to environment variables
   - Added multi-repo test documentation

### Test Results
```
=== All Tests Passed! ===
Summary:
  ✅ Per-request context routing works
  ✅ Multiple repos are properly isolated
  ✅ Concurrent operations succeed
  ✅ Daemon handles rapid context switching
```

### Files Modified/Added (Session 2)
- `integrations/beads-mcp/src/beads_mcp/tools.py` - uses daemon client ✅
- `integrations/beads-mcp/test_multi_repo.py` - NEW integration test ✅
- `integrations/beads-mcp/README.md` - daemon documentation ✅

Fix nil pointer crash in bd export command

When running `bd export -o .beads/issues.jsonl`, the command crashes with a nil pointer dereference.

## Error
```
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x108 pc=0x1034456fc]

goroutine 1 [running]:
main.init.func14(0x103c24380, {0x1034a9695?, 0x4?, 0x1034a95c9?})
        /Users/stevey/src/vc/adar/beads/cmd/bd/export.go:74 +0x15c
```

## Context
- This happened after closing bd-86, bd-91, bd-92
- Auto-export from daemon still works fine
- Only the manual `bd export` command crashes
- Data was already synced via auto-export, so no data loss

## Location

Add --global flag to daemon for multi-repo support

Currently daemon creates socket at .beads/bd.sock in each repo. For multi-repo support, add --global flag to create socket in ~/.beads/bd.sock that can serve requests from any repository.

Implementation:
- Add --global flag to daemon command
- When --global is set, use ~/.beads/bd.sock instead of ./.beads/bd.sock
- Don't require being in a git repo when --global is used
- Update daemon discovery logic to check ~/.beads/bd.sock as fallback
- Document that global daemon can serve multiple repos simultaneously

Benefits:
- Single daemon serves all repos on the system
- No need to start daemon per-repo
- Better resource usage
- Enables system-wide task tracking

Context: Per-request context routing (bd-92) already implemented - daemon can handle multiple repos. This issue is about making the UX better.

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

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

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

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

## Proposed Architecture

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

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

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

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

## Implementation Phases

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

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

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

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

## Risks & Mitigations

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

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

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

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

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

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

Event-driven daemon architecture

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

## Implementation Progress

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

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

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

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

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

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

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


Update AGENTS.md with event-driven mode

Document BEADS_DAEMON_MODE env var. Explain opt-in during Phase 1. Add troubleshooting for watcher failures.


Document multi-repo workflow with daemon

The daemon already supports multi-repo via per-request context routing (bd-92), but this isn't documented. Users need to know how to use beads across multiple projects.

Add documentation for:
1. How daemon serves multiple repos simultaneously
2. Starting daemon in one repo, using from others
3. MCP server multi-repo configuration
4. Example: tracking work across a dozen projects
5. Comparison to workspace/global instance approaches

Documentation locations:
- README.md (Multi-repo section)
- AGENTS.md (MCP multi-repo config)
- integrations/beads-mcp/README.md (working_dir parameter)

Include:
- Architecture diagram showing one daemon, many repos
- Example MCP config with BEADS_WORKING_DIR
- CLI workflow example
- Reference to test_multi_repo.py as proof of concept

Context: Feature already works (proven by test_multi_repo.py), just needs user-facing docs.

Batch Issue 1


Implement clone-scoped ID allocation to prevent N-way collisions

## Problem
Current ID allocation uses per-clone atomic counters (issue_counters table) that sync based on local database state. In N-way collision scenarios:
- Clone B sees {test-1} locally, allocates test-2
- Clone D sees {test-1, test-2, test-3} locally, allocates test-4
- When same content gets assigned test-2 and test-4, convergence fails

Root cause: Each clone independently allocates IDs without global coordination, leading to overlapping assignments for the same content.

## Solution
Add clone UUID to ID allocation to make every ID globally unique:

**Current format:** `test-1`, `test-2`, `test-3`
**New format:** `test-1-a7b3`, `test-2-a7b3`, `test-3-c4d9`

Where suffix is first 4 chars of clone UUID.

## Implementation

### 1. Add clone_identity table
```sql
CREATE TABLE clone_identity (
    clone_uuid TEXT PRIMARY KEY,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
```

### 2. Modify getNextIDForPrefix()
```go
func (s *SQLiteStorage) getNextIDForPrefix(ctx context.Context, prefix string) (string, error) {
    cloneUUID := s.getOrCreateCloneUUID(ctx)
    shortUUID := cloneUUID[:4]

    nextNum := s.getNextCounterForPrefix(ctx, prefix)
    return fmt.Sprintf("%s-%d-%s", prefix, nextNum, shortUUID), nil
}
```

### 3. Update ID parsing logic
All places that parse IDs (utils.ExtractIssueNumber, etc.) need to handle new format.

### 4. Migration strategy
- Existing IDs remain unchanged (no suffix)
- New IDs get clone suffix automatically
- Display layer can hide suffix in UI: `bd-cb64c226.3-a7b3` → `#42`

## Benefits
- **Zero collision risk**: Same content in different clones gets different IDs
- **Maintains readability**: Still sequential numbering within clone
- **No coordination needed**: Works offline, no central authority
- **Scales to 100+ clones**: 4-char hex = 65,536 unique clones

## Concerns
- ID format change may break existing integrations
- Need migration path for existing databases
- Display logic needs update to hide/show suffixes appropriately

## Success Criteria
- 10+ clone collision test passes without failures
- Existing issues continue to work (backward compatibility)
- Documentation updated with new ID format
- Migration guide for v1.x → v2.x

## Timeline
Medium-term (v1.1-v1.2), 2-3 weeks implementation

Backend task


Recurring dirty state after merge conflicts - bd sync keeps failing

## Problem

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

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

## Root Cause

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

## Current Workaround

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

## Example Session

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

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

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

## Lost Data in Recent Session

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

## Potential Solutions

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

## Related Issues

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

## Solution Implemented

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

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

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

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

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

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

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


Update docs for import bug fix

Update AGENTS.md, README.md, TROUBLESHOOTING.md with import.orphan_handling config documentation. Document resurrection behavior, tombstones, config modes. Add troubleshooting section for import failures with deleted parents.


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)

DetectCycles SQL query has bug preventing cycle detection

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

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

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

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

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

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


Document external_ref in content hash behavior

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

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

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

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

Support P-prefix priority format (P0-P4) in create and update commands


bd status "Recent Activity" is misleading - should use git history

## Problem

`bd status` shows "Recent Activity (last 7 days)" but the numbers are wrong. It only looks at database timestamps, not git history. Says "141 issues closed in last 7 days" when thousands have actually come and go.

## Issues

1. Only queries database timestamps, not git history
2. 7 days is too long a window
3. Numbers don't reflect actual activity in JSONL git history

## Proposed Fix

Either:
- Query git history of `.beads/beads.jsonl` to get actual activity (last 24-48 hours)
- Remove "Recent Activity" section entirely if not useful
- Make time window configurable and default to 24h

## Example Output (Current)
```
Recent Activity (last 7 days):
Issues Created:    174
Issues Closed:     141
Issues Updated:    37
```
This is misleading when thousands of issues have actually cycled through.


Improve integration test coverage for stateful features


Support separate branch for beads commits

Allow beads to commit to a separate branch (e.g., beads-metadata) using git worktrees to support protected main branch workflows.

Solves GitHub Issue #205 - Users need to protect main branch while maintaining beads workflow.

Key advantages:
- Works on any git platform
- Main branch stays protected
- No disruption to user's working directory
- Backward compatible (opt-in via config)
- Minimal disk overhead (sparse checkout)

Total estimate: 17-24 days (4-6 weeks with parallel work)


Integration test: mutation to export latency

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

GH#146: No color showing in terminal for some users

User reports color not working in macOS (Taho 26.0.1) with iTerm 3.6.4 and Terminal.app, despite color working elsewhere in terminal. Python rich and printf escape codes work.

Need to investigate:
- Is NO_COLOR env var set?
- Terminal type detection?
- fatih/color library configuration
- Does bd list show colors? bd ready? bd init?
- What's the output of: echo $TERM, echo $NO_COLOR

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

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

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

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


Clean up snapshot files after successful merge

After a successful 3-way merge and import during 'bd sync', the snapshot files (beads.base.jsonl, beads.left.jsonl, and their .meta.json files) are left in the .beads/ directory indefinitely.

These files are only needed temporarily during the merge process:
- beads.base.jsonl: snapshot from last successful import
- beads.left.jsonl: snapshot before git pull

Once the merge succeeds and the new JSONL is imported, these files serve no purpose and should be cleaned up.

Current behavior:
- sync.go:269 calls updateBaseSnapshot() after successful import
- UpdateBase() updates beads.base.jsonl to the new state
- beads.left.jsonl is never removed
- Both files accumulate in .beads/ directory

Expected behavior:
- After successful merge and import, clean up both snapshot files
- Only retain snapshots between sync operations (create on export, use during merge, clean up after import)

The cleanup logic exists (SnapshotManager.Cleanup()) but is only called on validation failures (deletion_tracking.go:48), not on success.

Discovered in vc project where stale snapshot files from Nov 8 merge were still present.

- Snapshot files are removed after successful merge and import
- Files are created fresh on next 'bd sync' export step
- Validation failure path still cleans up (existing behavior)
- Tests verify cleanup happens in success path

Ready issue


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

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

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

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

- Add db.SetMaxOpenConns(1) for :memory: databases only
- Verify VC test suite passes (37 previously failing tests)
- Add a test in Beads that reproduces the issue
- Document the pool limitation in code comments
- Release as Beads v0.21.7


Add tests for Integration Layer Implementation

While implementing bd-wfmw, noticed missing tests

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


Add migration registry and simplify New()

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


Address gosec security warnings (102 issues)

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

Review each gosec warning. Add exclusions for legitimate cases to .golangci.yml. Fix real security issues (overly permissive file modes).


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

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

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

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

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


Unit tests for Debouncer

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


Document Claude Code for Web SessionStart hook

Create documentation for using bd in Claude Code for Web:

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

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

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

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


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`


Extract Daemon struct and config into internal/daemonrunner

Create internal/daemonrunner with Config struct and Daemon struct. Move daemon runtime logic from cmd/bd/daemon.go Run function into Daemon.Start/Stop methods.

Refactoring complete! Created internal/daemonrunner package with:
- Config struct (config.go)
- Daemon struct with Start/Stop methods (daemon.go)
- RPC server lifecycle (rpc.go)
- Sync loop implementation (sync.go)
- Git operations (git.go)
- Process management (process.go, flock_*.go)
- Logger setup (logger.go)
- Platform-specific signal handling (signals_*.go)
- Database fingerprint validation (fingerprint.go)

Build succeeds and most daemon tests pass. Import functionality still delegated to cmd/bd (marked with TODO(bd-b5a3)).


Feature with design

This is a description


Add sync.branch configuration

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

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

Estimated effort: 1-2 days

- Can set sync.branch via config file, env var, or CLI
- bd config get sync.branch returns configured value
- Invalid branch names rejected with clear error
- Backward compatible (empty = current branch)


Wire config to import pipeline

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


Add ON DELETE CASCADE to child_counters schema

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


Audit Current Cache Usage

Understand exactly what code depends on the storage cache

- Document showing all cache dependencies
- Confirmation that removing cache won't break MCP
- List of tests that need updating

Files to examine:
- internal/rpc/server_cache_storage.go (cache implementation)
- internal/rpc/client.go (how req.Cwd is set)
- internal/rpc/server_*.go (all getStorageForRequest calls)
- integrations/beads-mcp/ (MCP multi-repo logic)

Tasks:
- Document all callers of getStorageForRequest()
- Verify req.Cwd is only set by RPC client for database discovery
- Confirm MCP server doesn't rely on multi-repo cache behavior
- Check if any tests assume multi-repo routing
- Review environment variables: BEADS_DAEMON_MAX_CACHE_SIZE, BEADS_DAEMON_CACHE_TTL, BEADS_DAEMON_MEMORY_THRESHOLD_MB

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

Final validation test


bd message: Add input validation for --importance flag

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

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

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

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


Create npm package structure with package.json

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

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

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

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

Support local-only git repos without remote origin

Daemon crashes when working with local git repos that don't have origin remote configured. Should gracefully degrade to local-only mode: skip git pull/push operations but maintain daemon features (RPC server, auto-flush, JSONL export).
