Create startup hook snippet for upgrade detection

Provide a reusable startup hook that agents can use to detect bd upgrades automatically.

## What to Create
A bash script snippet that:
1. Reads current bd version
2. Compares to last-seen version in metadata.json
3. Shows 'bd info --whats-new' output when version changes
4. Updates metadata.json with new version
5. Auto-runs 'bd hooks install' if hooks outdated

## Where to Document
- Create examples/hooks/startup-version-check.sh
- Document in AGENTS.md with usage instructions
- Add comment header explaining how to integrate with Claude Code, Cursor, etc.

## Key Features
- Works today with zero bd code changes
- Leverages existing bd info --whats-new
- Uses metadata.json for persistence
- Auto-fixes outdated git hooks

## Acceptance Criteria
- Script works standalone
- Clear integration instructions for popular AI environments
- Handles edge cases (no metadata.json, first run, etc.)


Test issue 2


Add guidance for self-hosting projects

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

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

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

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

Design hash ID generation algorithm

Design and specify the hash-based ID generation algorithm.

## Requirements
- Deterministic: same inputs → same ID
- Collision-resistant: ~2^32 space for 8-char hex
- Fast: <1μs per generation
- Includes timestamp for uniqueness
- Includes creator/workspace for distributed uniqueness

## Proposed Algorithm
```go
func GenerateIssueID(title, desc string, created time.Time, workspaceID string) string {
    h := sha256.New()
    h.Write([]byte(title))
    h.Write([]byte(desc))
    h.Write([]byte(created.Format(time.RFC3339Nano)))
    h.Write([]byte(workspaceID))
    hash := hex.EncodeToString(h.Sum(nil))
    return "bd-" + hash[:8]  // 8-char prefix = 2^32 space
}
```

## Open Questions
1. 8 chars (2^32) or 16 chars (2^64) for collision resistance?
2. Include priority/type in hash? (Pro: more entropy. Con: immutable)
3. How to handle workspace ID generation? (hostname? UUID?)
4. What if title+desc change? (Answer: ID stays same - hash only used at creation)

## Deliverables
- Design doc: docs/HASH_ID_DESIGN.md
- Collision probability analysis
- Performance benchmarks
- Prototype implementation in internal/types/id_generator.go


Fix bd doctor hash ID detection for short all-numeric hashes

bd doctor incorrectly flags hash-based IDs as sequential when they are short (3-4 chars) and all-numeric (e.g., pf-158).

Root cause: isHashID() in cmd/bd/migrate_hash_ids.go:328-358 uses faulty heuristic:
- For IDs < 5 chars, only returns true if contains letters
- But base36 hash IDs can be 3+ chars and all-numeric (MinLength: 3)
- Example: pf-158 is valid hash ID but flagged as sequential

Fix: Check multiple IDs (10-20 samples) instead of single-ID pattern matching:
- Sample IDs across database
- Check majority pattern (sequential vs hash format)
- Sequential: 1-4 digits (bd-1, bd-2...)
- Hash: 3-8 chars base36 (pf-158, pf-3s9...)

Impact: False positive warnings in bd doctor output


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.

Add --body-file flag to bd create for reading descriptions from files

## Problem

Creating issues with long/complex descriptions via CLI requires shell escaping gymnastics:

```bash
# Current workaround - awkward heredoc quoting
bd create --title="..." --description="$(cat <<'EOF'
...markdown...
EOF
)"

# Often fails with quote escaping errors in eval context
# Agents resort to writing temp files then reading them
```

## Proposed Solution

Add `--body-file` and `--description-file` flags to read description from a file, matching `gh` CLI pattern.

```bash
# Natural pattern that aligns with training data
cat > /tmp/desc.md << 'EOF'
...markdown content...
EOF

bd create --title="..." --body-file=/tmp/desc.md
```

## Implementation

### 1. Add new flags to `bd create`

```go
createCmd.Flags().String("body-file", "", "Read description from file (use - for stdin)")
createCmd.Flags().String("description-file", "", "Alias for --body-file")
```

### 2. Flag precedence

- If `--body-file` or `--description-file` is provided, read from file
- If value is `-`, read from stdin
- Otherwise fall back to `--body` or `--description` flag
- If neither provided, description is empty (current behavior)

### 3. Error handling

- File doesn't exist → clear error message
- File not readable → clear error message
- stdin specified but not available → clear error message

## Benefits

✅ **Matches training data**: `gh issue create --body-file file.txt` is a common pattern
✅ **No shell escaping issues**: File content is read directly
✅ **Works with any content**: Markdown, special characters, quotes, etc.
✅ **Agent-friendly**: Agents already write complex content to temp files
✅ **User-friendly**: Easier for humans too when pasting long descriptions

## Related Commands

Consider adding similar support to:
- `bd update --body-file` (for updating descriptions)
- `bd comment --body-file` (if/when we add comments)

## Examples

```bash
# From file
bd create --title="Add new feature" --body-file=feature.md

# From stdin
echo "Quick description" | bd create --title="Bug fix" --body-file=-

# With other flags
bd create \
  --title="Security issue" \
  --type=bug \
  --priority=0 \
  --body-file=security-report.md \
  --label=security
```

## Testing

- Test with normal files
- Test with stdin (`-`)
- Test with non-existent files (error handling)
- Test with binary files (should handle gracefully)
- Test with empty files (valid - empty description)
- Test that `--description-file` and `--body-file` are equivalent aliases

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.


Merge PR #300: gitignore upgrade feature

PR #300 is ready to merge but has rebase conflicts with main.

**Context:**
- PR implements 3 mechanisms for .beads/.gitignore upgrade (bd doctor --fix, daemon auto-upgrade, bd init idempotent)
- Conflicts resolved locally but diverged branches make push difficult
- All fixes applied: removed merge artifact, applied new gitignore template
- Clean scope: only 6 files changed (+194/-42)

**Next steps:**
1. Option A: Merge via GitHub UI (resolve conflicts in web interface)
2. Option B: Fresh rebase on main and force push
3. Verify CI passes
4. Squash and merge

PR URL: https://github.com/steveyegge/beads/pull/300
Fixes: #274


Create shared insert/event/dirty helpers

Create issues.go (insertIssue/insertIssues), events.go (recordCreatedEvent/recordCreatedEvents), dirty.go (markDirty/markDirtyBatch). Refactor single and bulk create paths to use these.


Test exclusive file reservations with two agents

Simulate two agents racing to claim the same issue and verify that exclusive reservations prevent collision.

Acceptance Criteria:
- Agent A reserves bd-123 → succeeds
- Agent B tries to reserve bd-123 → fails with clear error message
- Agent B can see who has the reservation
- Reservation expires after TTL
- Agent B can claim after expiration

Successfully tested file reservations:
- Agent BrownBear reserved bd-123 → granted
- Agent ChartreuseHill tried same → conflicts returned
- System correctly prevents collision


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.

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).


Add richer query capabilities to bd list

Current bd list filters are limited to basic field matching (status, priority, type, assignee, label). This forces users to resort to piping through jq for common queries.

Missing query capabilities:
- Pattern matching: --title-contains, --desc-contains
- Date ranges: --created-after, --updated-before, --closed-after
- Empty/null checks: --empty-description, --no-assignee, --no-labels
- Numeric ranges: --priority-min, --priority-max
- Complex boolean logic: --and, --or operators
- Full-text search: --search across all text fields
- Negation: --not-status, --exclude-label

Example use cases:
- Find issues with empty descriptions
- Find stale issues not updated in 30 days
- Find high-priority bugs with no assignee
- Search for keyword across title/description/notes

Implementation approach:
- Add query builder pattern to storage layer
- Support --query DSL for complex queries
- Keep simple flags for common cases
- Add --json output for programmatic use

## Progress Update

**Completed:**
- ✅ Extended IssueFilter struct with new fields (pattern matching, date ranges, empty/null checks, priority ranges)
- ✅ Updated SQLite SearchIssues implementation
- ✅ Added CLI flags to list.go
- ✅ Added parseTimeFlag helper
- ✅ Comprehensive tests added - all passing

**Remaining:**
- ⚠ RPC layer needs updating (internal/rpc/protocol.go ListArgs)
- ⚠ Daemon handler needs to forward new filters
- ⚠ End-to-end testing with daemon mode
- 📝 Documentation updates

**Files Modified:**
- internal/types/types.go
- internal/storage/sqlite/sqlite.go
- cmd/bd/list.go
- cmd/bd/list_test.go

**Next Steps:**
1. Update RPC protocol
2. Update daemon handler
3. Test with daemon mode
4. Update docs


TestHooksCheckGitHooks failing - version mismatch (0.23.0 vs 0.23.1)

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

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

This is blocking the landing of GH #274 fix.


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).


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.

Document -short flag in testing guide

Add documentation about the -short flag and how it's used to skip slow tests. Should explain that developers can run 'go test -short ./...' for fast iteration and 'go test ./...' for full coverage.


Remove misleading placeholder 'bd merge' command from duplicates output

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

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

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

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

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

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

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


Multi-repo hydration layer

Test child issue


Add tests for performFlush error handling in FlushManager

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

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

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

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

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

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


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.


Implement topological sort for import ordering

Refactor upsertIssues() to sort issues by hierarchy depth before batch creation. Ensures parents are created before children, fixing latent bug where parent-child pairs in same batch can fail if ordered wrong. Sort by dot count, create in depth-order batches (0→1→2→3).


Propagate context through command handlers

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

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

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

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

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

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

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

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

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


Document shared memory test isolation pattern in test_helpers.go

Tests were failing because :memory: creates a shared database across all tests. The fix is to use "file::memory:?mode=memory&cache=private" for test isolation.

Should document this pattern in test_helpers.go and potentially update newTestStore to use private memory by default.


Clarify JSONL size bounds with multi-repo

The contributor-workflow-analysis.md states (line 226): 'Keep beads.jsonl small enough for agents to read (<25k)'

With multi-repo hydration, it's unclear whether this bound applies to:
- Each individual JSONL file (likely intention)
- The total hydrated size across all repos (unclear)
- Both (most conservative)

Clarification needed because:
- VC monitors .beads/issues.jsonl size to stay under limit
- With multi-repo, VC needs to know if each additional repo also has 25k limit
- Agents reading hydrated data need to know total size bounds
- Performance characteristics depend on total vs per-repo limits

Example scenario:
- Primary repo: 20k JSONL
- Planning repo: 15k JSONL
- Total hydrated: 35k
Is this acceptable or does it violate the <25k principle?


Consider central serialization package for JSON handling

Multiple parts of the codebase handle JSON serialization of issues with slightly different approaches. Consider creating a centralized serialization package to ensure consistency.

Current serialization locations:
- `cmd/bd/export.go` - JSONL export (issues to file)
- `cmd/bd/import.go` - JSONL import (file to issues)
- `internal/rpc/protocol.go` - RPC JSON marshaling
- `internal/storage/memory/memory.go` - In-memory marshaling

Potential benefits:
- Single source of truth for JSON format
- Consistent field naming
- Easier to add new fields
- Centralized validation

Note: This is marked **optional** because:
- Current serialization mostly works
- May not provide enough benefit to justify refactor
- Risk of breaking compatibility

Decision point: Evaluate if benefits outweigh refactoring cost

Impact: TBD based on investigation - may defer to future work


Fix import failure on missing parent issues

Import process fails atomically when JSONL references deleted parent issues. Implement hybrid solution: topological sorting + parent resurrection to handle deleted parents gracefully while maintaining referential integrity. See docs/import-bug-analysis-bd-3xq.md for full analysis.


Migration tool: sequential → hash IDs

Create migration tool to convert existing sequential-ID databases to hash-ID format.

## Command: bd migrate --hash-ids

```bash
bd migrate --hash-ids [--dry-run]
```

## Migration Process

### 1. Backup Database
```bash
cp .beads/beads.db .beads/beads.db.backup-1761798384
echo "✓ Backup created: .beads/beads.db.backup-1234567890"
```

### 2. Generate Hash IDs for Existing Issues
```go
func migrateToHashIDs(db *SQLiteStorage) error {
    // Read all issues
    issues, err := db.ListIssues(ctx, ListOptions{Status: "all"})

    // Generate mapping: old ID → new hash ID
    mapping := make(map[string]string)
    for _, issue := range issues {
        hashID := GenerateHashID(
            issue.Title,
            issue.Description,
            issue.CreatedAt,
            db.workspaceID,
        )
        mapping[issue.ID] = hashID
    }

    // Detect hash collisions (extremely rare)
    if hasCollisions(mapping) {
        return fmt.Errorf("hash collision detected, aborting")
    }

    return nil
}
```

### 3. Update Database Schema
```sql
-- Add alias column
ALTER TABLE issues ADD COLUMN alias INTEGER UNIQUE;

-- Populate aliases from old IDs
UPDATE issues SET alias = CAST(SUBSTR(id, 4) AS INTEGER)
  WHERE id LIKE 'bd-%' AND SUBSTR(id, 4) GLOB '[0-9]*';

-- Create new issues_new table with hash IDs
CREATE TABLE issues_new (
    id TEXT PRIMARY KEY,  -- Hash IDs now
    alias INTEGER UNIQUE,
    title TEXT NOT NULL,
    -- ... rest of schema
);

-- Copy data with ID mapping
INSERT INTO issues_new SELECT
    <new_hash_id>,  -- From mapping
    alias,
    title,
    -- ...
FROM issues;

-- Drop old table, rename new
DROP TABLE issues;
ALTER TABLE issues_new RENAME TO issues;
```

### 4. Update Dependencies
```sql
-- Update depends_on_id using mapping
UPDATE dependencies
SET issue_id = <new_hash_id>,
    depends_on_id = <new_depends_on_hash_id>
FROM mapping;
```

### 5. Update Text References
```go
// Update all text fields that mention old IDs
func updateTextReferences(db *SQLiteStorage, mapping map[string]string) error {
    for oldID, newID := range mapping {
        // Update description, notes, design, acceptance_criteria
        db.Exec(`UPDATE issues SET
            description = REPLACE(description, ?, ?),
            notes = REPLACE(notes, ?, ?),
            design = REPLACE(design, ?, ?),
            acceptance_criteria = REPLACE(acceptance_criteria, ?, ?)
        `, oldID, newID, oldID, newID, oldID, newID, oldID, newID)
    }
}
```

### 6. Export to JSONL
```bash
bd export  # Writes hash IDs to .beads/issues.jsonl
git add .beads/issues.jsonl
git commit -m "Migrate to hash-based IDs"
```

## Output
```bash
$ bd migrate --hash-ids
Migrating to hash-based IDs...
✓ Backup created: .beads/beads.db.backup-1730246400
✓ Generated 150 hash IDs
✓ No hash collisions detected
✓ Updated issues table schema
✓ Updated 150 issue IDs
✓ Updated 87 dependencies
✓ Updated 234 text references
✓ Exported to .beads/issues.jsonl
✓ Migration complete!

Next steps:
  1. Test: bd list, bd show #1, etc.
  2. Commit: git commit -m "Migrate to hash-based IDs"
  3. Push: git push origin main
  4. Notify collaborators to pull and re-init
```

## Dry Run Mode
```bash
$ bd migrate --hash-ids --dry-run
[DRY RUN] Would migrate 150 issues:
  bd-1c63eb84   → bd-af78e9a2  (alias: #1)
  bd-9063acda   → bd-e5f6a7b8  (alias: #2)
  ...
  bd-150 → bd-9a8b7c6d  (alias: #150)

[DRY RUN] Would update:
  - 150 issue IDs
  - 87 dependencies
  - 234 text references in descriptions/notes

No changes made. Run without --dry-run to apply.
```

## Files to Create
- cmd/bd/migrate.go (new command)
- internal/storage/sqlite/migrations/hash_ids.go

## Testing
- Test migration on small database (10 issues)
- Test migration on large database (1000 issues)
- Test hash collision detection (inject collision artificially)
- Test text reference updates
- Test rollback (restore from backup)
- Test migrated database works correctly

## Rollback Procedure
```bash
# If migration fails or has issues
mv .beads/beads.db.backup-1234567890 .beads/beads.db
bd export  # Restore JSONL from backup DB
```

## Multi-Clone Coordination
**Important**: All clones must migrate before syncing:

1. Coordinator sends message: "Migrating to hash IDs on 2025-10-30 at 10:00 UTC"
2. All collaborators pull latest changes
3. All run: `bd migrate --hash-ids`
4. All push changes
5. New work can continue with hash IDs

**Do NOT**:
- Mix sequential and hash IDs in same database
- Sync before all clones migrate

Investigate and upgrade to modernc.org/sqlite 1.39.1+

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

**Issue:** [deleted:bd-cb64c226.2], GH #144

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

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

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

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


Refactor: Move staleness check inside daemon branch

## Problem

Currently ensureDatabaseFresh() is called before the daemon mode check, but it checks daemonClient != nil internally and returns early. This is redundant.

**Location:** All read commands (list.go:196, show.go:27, ready.go:102, status.go:80, etc.)

## Current Pattern

Call happens before daemon check, function checks daemonClient internally.

## Better Pattern

Move staleness check to direct mode branch only, after daemon check.

## Impact
Low - minor performance improvement (avoids one function call per command in daemon mode)

## Effort
Medium - requires refactoring 8 command files

## Priority
Low - can defer to future cleanup PR


Remove unreachable utility functions

Several small utility functions are unreachable:

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

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

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

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

Impact: Removes 50-100 LOC depending on decisions


Add 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.


Standardize --dry-run flag across all commands

Replace all instances of --preview with --dry-run for consistency.

**Commands to update:**
- clean: Change --preview to --dry-run

**Commands to verify:**
- cleanup, compact, delete, duplicates, epic close-eligible, import, sync

**Testing:**
- Ensure all mutating commands support --dry-run
- Verify backward compatibility (deprecation warning for --preview?)
- Update tests and documentation

All commands already use --dry-run consistently. Verified:
- cleanup: line 130
- compact: line 873
- delete: line 559
- duplicates: line 158
- import: line 703
- sync: line 333
- epic close-eligible: line 208
- clean: line 162

No --preview flags found in the codebase. This task appears to have been completed before the epic was created.


Add integration tests for adapter library

Test suite for beads_mail_adapter.py covering all scenarios.

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

File: lib/test_beads_mail_adapter.py

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

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

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

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


bd-hv01: 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

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


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)


MCP server: "No workspace set" and "chunk longer than limit" errors

Two related errors reported in beads-mcp v0.21:

**Error 1: "No workspace set" after successful set_context**
```
✓ Set beads context
✗ list
  Error calling tool 'list': No workspace set. Either provide workspace_root
  parameter or call set_context() first.
```

Hypothesis: Environment variable persistence issue between MCP tool calls, or ContextVar not being set correctly by @with_workspace decorator.

**Error 2: "Separator is found, but chunk is longer than limit"**
```
✗ list
  Error calling tool 'list': Separator is found, but chunk is longer than limit
```

Hypothesis: MCP protocol output size limit exceeded. Large issue databases may produce JSON output that exceeds MCP stdio buffer limits.

Platform: Fedora 43, using copilot-cli with Sonnet 4.5

Workaround: CLI works fine (`bd list --status open --json`)

## Fixes Implemented

**Issue 1: "No workspace set" after successful set_context** ✅ FIXED

Root cause: os.environ doesn't persist across MCP tool calls. When set_context() set BEADS_WORKING_DIR in os.environ, that change was lost on the next tool call.

Solution:
- Added module-level _workspace_context dict for persistent storage (server.py:51)
- Modified set_context() to store in both persistent dict and os.environ (server.py:265-287)
- Modified with_workspace() decorator to check persistent context first (server.py:129-133)
- Updated where_am_i() to check persistent context (server.py:302-330)

**Issue 2: "chunk longer than limit"** ✅ FIXED

Root cause: MCP stdio protocol has buffer limits. Large issue lists with full dependencies/dependents exceed this.

Solution:
- Reduced default list limit from 50 to 20 (server.py:356, models.py:122)
- Reduced max list limit from 1000 to 100 (models.py:122)
- Strip dependencies/dependents from list() and ready() responses (server.py:343-350, 368-373)
- Full dependency details still available via show() command

## Testing

✅ Python syntax validated with py_compile
✅ Changes are backward compatible
✅ Persistent context falls back to os.environ for compatibility

Users should now be able to call set_context() once and have it persist across all subsequent tool calls. Large databases will no longer cause buffer overflow errors.


Remove obsolete renumber.go command (hash IDs eliminated need)


Daemon crashes silently on RPC query after startup

The daemon fails to handle 'show' RPC commands when:
1) JSONL is newer than database (needs import)
2) git pull fails due to uncommitted changes

Symptoms:
- Daemon appears to run (ps shows process)
- 'bd list' and other commands work fine
- 'bd show <id>' returns "failed to read response: EOF"
- No panic or error logged in daemon.log

Root cause likely: auto-import deadlock or state corruption when import is blocked by git conflicts.

Workaround:
- Restart daemon after syncing git state (commit/push changes)
- OR use --no-daemon flag for all commands

The panic recovery added in server_lifecycle_conn.go:183 didn't catch any panics, confirming this isn't a panic-based crash.

Root cause found and fixed: Two bugs - (1) nil pointer check missing in handleShow causing panic, (2) double JSON encoding in show.go ID resolution. Both fixed. bd show now works with daemon.


Add template support for issue creation

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

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

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

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


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)

Optimize cmd/bd test suite performance (currently 30+ minutes)

CLI test suite is extremely slow (~30+ minutes for full run). Tests are poorly designed and need performance optimization before expanding coverage.

Current coverage: 24.8% (improved from 20.2%)

**Problem**: Tests take far too long to run, making development iteration painful.

**Priority**: Fix test performance FIRST, then consider increasing coverage.

**Investigation needed**:
- Profile test execution to identify bottlenecks
- Look for redundant git operations, database initialization, or daemon operations
- Identify opportunities for test parallelization
- Consider mocking or using in-memory databases where appropriate
- Review test design patterns

**Related**: bd-ktng mentions 13 CLI tests with redundant git init calls (31s total)

**Goal**: Get full test suite under 1-2 minutes before adding more tests.


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

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

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

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

## Root Cause Analysis

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

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

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

## Solution Implemented

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

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

## File Path Handling

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


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.

bd-hv01: Add comprehensive edge case tests for deletion tracking

Need to add tests for: corrupted snapshot file, stale snapshot (> 1 hour), concurrent sync operations (daemon + manual), partial deletion failure, empty remote JSONL, multi-repo mode with deletions, git worktree scenario.

Also refine TestDeletionWithLocalModification to check for specific conflict error instead of accepting any error.

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

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

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

## Final Implementation

Cleanest possible approach - no internal helper methods needed:

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

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

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


Split monolithic sqlite.go into focused files

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

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

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

Effort: 6-8 hours


Investigate and upgrade to modernc.org/sqlite 1.39.1+

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

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

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

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

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

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


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 message: Refactor duplicated error messages


Log errors from timer-triggered flushes instead of discarding


bd export should detect and prevent stale database exports

## Problem

When `bd export` is run with a stale database (older than issues.jsonl), it silently overwrites the JSONL file with stale data, causing data loss.

## What Happened (vc project)

1. Agent A created 4 new issues and exported to issues.jsonl (commit 99a9d58)
2. Agent A closed an issue and exported again (commit 58b4613) - JSONL now has 4 epics
3. Agent B had stale database (from before step 1)
4. Agent B worked on unrelated issue and exported (commit 0609233)
5. Agent B's export **overwrote issues.jsonl**, removing the 4 epics created by Agent A
6. Required manual recovery by re-exporting from Agent A's correct database

## Expected Behavior

`bd export` should detect that the database is stale and either:
- **Refuse to export** with error message explaining the issue
- **Warn prominently** and require explicit --force flag to override
- **Auto-import first** to sync database before exporting

## How to Detect Staleness

Compare modification times (similar to VC's ValidateDatabaseFreshness):
1. Check .db, .db-wal, .db-shm timestamps (use newest for WAL mode)
2. Check issues.jsonl timestamp
3. If JSONL is newer by >1 second: database is stale

## Suggested Fix

Add staleness check in `bd export`:

```go
func Export(dbPath, jsonlPath string, force bool) error {
    // Check if database is stale
    if !force {
        if err := checkDatabaseFreshness(dbPath, jsonlPath); err != nil {
            return fmt.Errorf("database is stale: %w\n" +
                "Run 'bd import %s' first to sync, or use --force to override",
                err, jsonlPath)
        }
    }

    // Proceed with export...
}
```

## Impact

- **Severity**: High (silent data loss)
- **Frequency**: Happens in multi-agent workflows when agents don't sync
- **Workaround**: Manual recovery (re-export from correct database)

## References

- VC issue tracker: commits 58b4613 -> 0609233 -> c41c638
- VC has similar check: `storage.ValidateDatabaseFreshness()`
- Tolerance: 1 second (handles filesystem timestamp precision)

Fixed with ID-based comparison instead of just count. Now detects:
1. DB has fewer issues than JSONL (count check)
2. DB has different issues than JSONL (ID comparison)

Both scenarios now properly refuse export unless --force is used.

Implementation uses getIssueIDsFromJSONL() to build a set of IDs from JSONL, then checks if any JSONL IDs are missing from DB. Shows specific missing issue IDs in error message.


Rapid 2


Document CLI + hooks as recommended approach over MCP

Update documentation to position CLI + bd prime hooks as the primary recommended approach over MCP server, explaining why minimizing context matters even with large context windows (compute cost, energy, environment, latency).


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.


Investigate database pollution - unexpected issue count increases

Two repositories showing unexpected issue counts:
- ~/src/beads: 280 issues (expected ~209-220)
- ~/src/dave/beads: 895 issues (675 open, 149 closed)

This suggests database pollution - issues from one repository leaking into another. Need to investigate:
1. Run bd detect-pollution on both repos
2. Check for cross-repo contamination
3. Identify source of pollution (daemon? multi-repo config? import issues?)
4. Clean up polluted databases
5. Prevent future pollution


Test: N-clone scenario with hash IDs (no collisions)

Comprehensive test to verify hash IDs eliminate collision problems.

## Test: TestHashIDsNClones

### Purpose
Verify that N clones can work offline and sync without ID collisions using hash IDs.

### Test Scenario
```
Setup:
- 1 bare remote repo
- 5 clones (A, B, C, D, E)

Offline Work:
- Each clone creates 10 issues with different titles
- No coordination, no network access
- Total: 50 unique issues

Sync:
- Clones sync in random order
- Each pull/import other clones' issues

Expected Result:
- All 5 clones converge to 50 issues
- Zero ID collisions
- Zero remapping needed
- Alias conflicts resolved deterministically
```

### Implementation
File: cmd/bd/beads_hashid_test.go (new)

```go
func TestHashIDsFiveClones(t *testing.T) {
    tmpDir := t.TempDir()
    remoteDir := setupBareRepo(t, tmpDir)

    // Setup 5 clones
    clones := make(map[string]string)
    for _, name := range []string{"A", "B", "C", "D", "E"} {
        clones[name] = setupClone(t, tmpDir, remoteDir, name)
    }

    // Each clone creates 10 issues offline
    for name, dir := range clones {
        for i := 0; i < 10; i++ {
            createIssue(t, dir, fmt.Sprintf("%s-issue-%d", name, i))
        }
        // No sync yet!
    }

    // Sync in random order
    syncOrder := []string{"C", "A", "E", "B", "D"}
    for _, name := range syncOrder {
        syncClone(t, clones[name], name)
    }

    // Final convergence round
    for _, name := range []string{"A", "B", "C", "D", "E"} {
        finalPull(t, clones[name], name)
    }

    // Verify all clones have all 50 issues
    for name, dir := range clones {
        issues := getIssues(t, dir)
        if len(issues) != 50 {
            t.Errorf("Clone %s: expected 50 issues, got %d", name, len(issues))
        }

        // Verify all issue IDs are hash-based
        for _, issue := range issues {
            if !strings.HasPrefix(issue.ID, "bd-") || len(issue.ID) != 11 {
                t.Errorf("Invalid hash ID: %s", issue.ID)
            }
        }
    }

    // Verify no collision resolution occurred
    // (This would be in logs if it happened)

    t.Log("✓ All 5 clones converged to 50 issues with zero collisions")
}
```

### Edge Case Tests

#### Test: Hash Collision Detection (Artificial)
```go
func TestHashCollisionDetection(t *testing.T) {
    // Artificially inject collision by mocking hash function
    // Verify system detects and handles it
}
```

#### Test: Alias Conflicts Resolved Deterministically
```go
func TestAliasConflictsNClones(t *testing.T) {
    // Two clones assign same alias to different issues
    // Verify deterministic resolution (content-hash ordering)
    // Verify all clones converge to same alias assignments
}
```

#### Test: Mixed Sequential and Hash IDs (Should Fail)
```go
func TestMixedIDsRejected(t *testing.T) {
    // Try to import JSONL with sequential IDs into hash-ID database
    // Verify error or warning
}
```

### Performance Test

#### Benchmark: Hash ID Generation
```go
func BenchmarkHashIDGeneration(b *testing.B) {
    for i := 0; i < b.N; i++ {
        GenerateHashID("title", "description", time.Now(), "workspace-id")
    }
}

// Expected: < 1μs per generation
```

#### Benchmark: N-Clone Convergence Time
```go
func BenchmarkNCloneConvergence(b *testing.B) {
    for _, n := range []int{3, 5, 10, 20} {
        b.Run(fmt.Sprintf("N=%d", n), func(b *testing.B) {
            // Measure total convergence time
        })
    }
}

// Expected: Linear scaling O(N)
```

### Acceptance Criteria
- TestHashIDsFiveClones passes reliably (10/10 runs)
- Zero ID collisions in any scenario
- All clones converge in single round (not multi-round like old system)
- Alias conflicts resolved deterministically
- Performance benchmarks meet targets (<1μs hash gen)

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

## Comparison to Old System
This test replaces:
- TestTwoCloneCollision (bd-71107098) - no longer needed
- TestThreeCloneCollision (bd-cbed9619) - no longer needed
- TestFiveCloneCollision (bd-a40f374f) - no longer needed

Old system required complex collision resolution and multi-round convergence.
New system: single-round convergence with zero collisions.


CI failing on all 3/4 test jobs despite individual tests passing

CI has been broken for a day+ with mysterious test failures. Issue #173 on GitHub tracks this.

## Current Status
- **Lint job**: ✅ PASSING
- **Test (Linux)**: ❌ FAILING (exit code 1)
- **Test (Windows)**: ❌ FAILING (exit code 1)
- **Test Nix Flake**: ❌ FAILING (exit code 1)

## Key Observations
All three failing jobs show identical pattern:
- Individual test output shows PASS for every test
- Final result: `FAIL github.com/steveyegge/beads/cmd/bd`
- Exit code 1 despite no visible test failures
- Last visible test output before failure: "No Reason Issue" test (TestCloseCommand/close_without_reason)

## Investigation So Far
1. All tests appear to pass when examined individually
2. Likely causes:
   - Race detector finding data races during test cleanup (`-race` flag)
   - Panic/error occurring after main tests complete
   - Test harness issue not reporting actual failure
   - Possible regression from PR #203 (dependency_type changes)

## Recent CI Runs
- Run 19015040655 (latest): 3/4 failing
- Multiple recent commits tried to fix Windows/lint issues
- Agent on rrnewton/beads fork attempting fixes (2/4 passing there)

## Next Steps
1. Run tests locally with `-race -v` to see full output
2. Check for unreported test failures or panics
3. Examine test cleanup/teardown code
4. Review recent changes around close command tests
5. Consider if race detector is too sensitive or catching real issues

## Progress Update

### ✅ Fixed (commits 09bd4d3, 21a29bc)
1. **Daemon auto-import** - Always recompute content_hash in importer to avoid stale hashes
2. **TestScripts failures** - Added bd binary to PATH for shell subprocess tests
3. **Test infrastructure** - Added .gitignore to test repos, fixed last_import_time metadata

### ✅ CI Status (Run 19015638968)
- **Test (Linux)**: ✅ SUCCESS - All tests passing
- **Test (Windows)**: ❌ FAILURE - Pre-existing Windows test failures
- **Test Nix Flake**: ❌ FAILURE - Build fails with same test errors
- **Lint**: ❌ FAILURE - Pre-existing issue in migrate.go:647

### ❌ Remaining Issues (not related to original bd-1231)

**Windows failures:**
- TestFindDatabasePathEnvVar
- TestHashIDs_MultiCloneConverge
- TestHashIDs_IdenticalContentDedup
- TestDatabaseReinitialization (5 subtests)
- TestFindBeadsDir_NotFound
- TestMetricsSnapshot/uptime

**Lint failure:**
- cmd/bd/migrate.go:647:37: cleanupWALFiles - result 0 (error) is always nil (unparam)

**Nix failure:**
- Build fails during test phase with same test errors

### Next Steps
1. Investigate Windows-specific test failures
2. Fix linting issue in migrate.go
3. Debug Nix build test failures


Improve integration test coverage for stateful features


Export deduplication breaks when JSONL and export_hashes table diverge

## Problem

The export deduplication feature (timestamp-only skipping) breaks when the JSONL file and export_hashes table get out of sync, causing exports to skip issues that aren't actually in the file.

## Symptoms

- `bd export` reports "Skipped 128 issue(s) with timestamp-only changes"
- JSONL file only has 38 lines but DB has 149 issues
- export_hashes table has 149 entries
- Auto-import doesn't trigger (hash matches despite missing data)
- Two repos on same commit show different issue counts

## Root Cause

shouldSkipExport() in autoflush.go compares current issue hash with stored export_hashes entry. If they match, it skips export assuming the issue is already in the JSONL.

This assumption fails when:
1. Git operations (pull, reset, checkout) change JSONL without clearing export_hashes
2. Manual JSONL edits or corruption
3. Import operations that modify DB but don't update export_hashes
4. Partial exports that update export_hashes but don't complete

## Impact

- **Critical data loss risk**: Issues appear to be tracked but aren't persisted to git
- Breaks multi-repo sync (root cause of today's debugging session)
- Auto-import fails to detect staleness (hash matches despite missing data)
- Silent data corruption (no error messages, just missing issues)

## Reproduction

1. Have DB with 149 issues, all in export_hashes table
2. Truncate JSONL to 38 lines (simulate git reset or corruption)
3. Run `bd export` - it skips 128 issues
4. JSONL still has only 38 lines but export thinks it succeeded

## Current Workaround

```bash
sqlite3 .beads/beads.db "DELETE FROM export_hashes"
bd export -o .beads/beads.jsonl
```

## Proposed Solutions

**Option 1: Verify JSONL integrity before skipping**
- Count lines in JSONL, compare with export_hashes count
- If mismatch, clear export_hashes and force full export
- Safe but adds I/O overhead

**Option 2: Hash-based JSONL validation**
- Store hash of entire JSONL file in metadata
- Before export, check if JSONL hash matches
- If mismatch, clear export_hashes
- More efficient, detects any JSONL corruption

**Option 3: Disable timestamp-only deduplication**
- Remove the feature entirely
- Always export all issues
- Simplest and safest, but creates larger git commits

**Option 4: Clear export_hashes on git operations**
- Add post-merge hook to clear export_hashes
- Clear on any import operation
- Defensive approach but may over-clear

## Recommended Fix

Combination of Options 2 + 4:
1. Store JSONL file hash in metadata after export
2. Check hash before export, clear export_hashes if mismatch
3. Clear export_hashes on import operations
4. Add `bd validate` check for JSONL/export_hashes sync

## Files Involved

- cmd/bd/autoflush.go (shouldSkipExport)
- cmd/bd/export.go (export with deduplication)
- internal/storage/sqlite/metadata.go (export_hashes table)

## Recovery Session (2025-10-29 21:30)

### What Happened
- Created 14 new hash ID issues (bd-f8b764c9 through bd-f8b764c9.1)
- bd sync appeared to succeed
- Canonical repo (~/src/beads): 162 issues in DB + JSONL ✓
- Secondary repo (fred/beads): Only 145 issues vs 162 in canonical ✗
- Both repos on same git commit but different issue counts!

### Bug Manifestation During Recovery

1. **Initial state**: fred/beads had 145 issues, 145 lines in JSONL, 145 export_hashes entries

2. **After git reset --hard origin/main**:
   - JSONL: 162 lines (from git)
   - DB: 150 issues (auto-import partially worked)
   - Auto-import failed with UNIQUE constraint error

3. **After manual import --resolve-collisions**:
   - DB: 160 issues
   - JSONL: Still 162 lines
   - export_hashes: 159 entries

4. **After bd export**:
   - **JSONL reduced to 17 lines!** ← The bug in action
   - export_hashes: 159 entries (skipped exporting 142 issues)
   - Silent data loss - no error message

5. **After clearing export_hashes and re-export**:
   - JSONL: 159 lines (missing 3 issues still)
   - DB: 159 issues
   - Still diverged from canonical

### The Bug Loop
Once export_hashes and JSONL diverge:
- Export skips issues already in export_hashes
- But those issues aren't actually in JSONL
- This creates corrupt JSONL with missing issues
- Auto-import can't detect the problem (file hash matches what was exported)
- Data is lost with no error messages

### Recovery Solution
Couldn't break the loop with export alone. Had to:
1. Copy .beads/beads.db from canonical repo
2. Clear export_hashes
3. Full re-export
4. Finally converged to 162 issues

### Key Learnings

1. **The bug is worse than we thought**: It can create corrupt exports (17 lines instead of 162!)

2. **Auto-import can't save you**: Once export is corrupt, auto-import just imports the corrupt data

3. **Silent failure**: No warnings, no errors, just missing issues

4. **Git operations trigger it**: git reset, git pull, etc. change JSONL without clearing export_hashes

5. **Import operations populate export_hashes**: Even manual imports update export_hashes, setting up future export failures

### Immediate Action Required

**DISABLE EXPORT DEDUPLICATION NOW**

This feature is fundamentally broken and causes data loss. Should be disabled until properly fixed.

Quick fix options:
- Set environment variable to disable feature
- Comment out shouldSkipExport check
- Always clear export_hashes before export
- Add validation that DB count == JSONL line count before allowing export

### Long-term Fix

Need Option 2 + 4 from proposed solutions:
1. Store JSONL file hash after every successful export
2. Before export, verify JSONL hash matches expected
3. If mismatch, log WARNING and clear export_hashes
4. Clear export_hashes on every import operation
5. Add git post-merge hook to clear export_hashes
6. Add `bd validate` command to detect divergence


Document bd info --whats-new in AGENTS.md

Add prominent documentation about bd info --whats-new to help agents discover upgrade changes.

## Changes Needed
1. Add to 'What's New' section (line 13-28): Emphasize running bd info --whats-new after upgrades
2. Add to 'Pro Tips for Agents' section (line 474-486): Include version check in session startup routine
3. Document the bd hooks install command for keeping hooks in sync

## Implementation
- Update AGENTS.md with clear examples
- Show both human-readable and --json output options
- Link to the discussion #239 as motivation

## Acceptance Criteria
- Agents know to run bd info --whats-new after upgrades
- Clear guidance on when/why to use it
- Examples showing both output formats


Test issue


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.


Implement filesystem shims for WASM

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

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

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


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 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


Delete collision resolution code

Remove ~2,100 LOC of ID collision detection and resolution code (no longer needed with hash IDs).

## Files to Delete Entirely
```
internal/storage/sqlite/collision.go              (~800 LOC)
internal/storage/sqlite/collision_test.go         (~300 LOC)
cmd/bd/autoimport_collision_test.go               (~400 LOC)
```

## Code to Remove from Existing Files

### internal/importer/importer.go
Remove:
- `DetectCollisions()` calls
- `ScoreCollisions()` logic
- `RemapCollisions()` calls
- `handleRename()` function
- All collision-related error handling

Keep:
- Basic import logic
- Exact match detection (idempotent import)

### beads_twoclone_test.go
Remove:
- `TestTwoCloneCollision` (bd-71107098)
- `TestThreeCloneCollision` (bd-cbed9619)
- `TestFiveCloneCollision` (bd-a40f374f)
- All N-way collision tests

### cmd/bd/import.go
Remove:
- `--resolve-collisions` flag
- `--dry-run` collision preview
- Collision reporting

## Issues Closed by This Change
- bd-71107098: Add test for symmetric collision
--89: Content-hash collision resolution
- bd-cbed9619: N-way collision resolution epic
- bd-cbed9619.5: Add ScoreCollisions (already done but now unnecessary)
- bd-cbed9619.4: Make DetectCollisions read-only
- bd-cbed9619.3: ResolveNWayCollisions function
- bd-cbed9619.2: Multi-round import convergence
- bd-cbed9619.1: Multi-round convergence for N-way collisions
- bd-e6d71828: Transaction + retry logic for collisions
- bd-70419816: Test case for symmetric collision

## Verification Steps
1. `grep -r "collision" --include="*.go"` → should only find alias conflicts
2. `go test ./...` → all tests pass
3. `go build ./cmd/bd` → clean build
4. Check LOC reduction: `git diff --stat`

## Expected Metrics
- **Files deleted**: 3
- **LOC removed**: ~2,100
- **Test coverage**: Should increase (less untested code)
- **Binary size**: Slightly smaller

## Caution
Do NOT delete:
- Alias conflict resolution (new code in bd-f8b764c9.6)
- Duplicate detection (bd-581b80b3, bd-149) - different from ID collisions
- Merge conflict resolution (bd-7e7ddffa.1, bd-5f483051) - git conflicts, not ID collisions

## Files to Modify
- internal/importer/importer.go (remove collision handling)
- cmd/bd/import.go (remove --resolve-collisions flag)
- beads_twoclone_test.go (remove collision tests)
- Delete: internal/storage/sqlite/collision.go
- Delete: internal/storage/sqlite/collision_test.go
- Delete: cmd/bd/autoimport_collision_test.go

## Testing
- Ensure all remaining tests pass
- Manual test: create issue on two clones, sync → no collisions
- Verify error if somehow hash collision occurs (extremely unlikely)


Audit and fix JSONL filename mismatches across all repo clones

## Problem

Multiple clones of repos are configured with different JSONL filenames (issues.jsonl vs beads.jsonl), causing:
1. JSONL files to be resurrected after deletion (one clone pushes issues.jsonl, another pushes beads.jsonl)
2. Agents unable to see issues filed by other agents after sync
3. Merge conflicts and data inconsistencies

## Root Cause

When repos were "bd doctored" or initialized at different times, some got issues.jsonl (old default) and others got beads.jsonl (Beads repo specific). These clones push their respective files, creating duplicates.

## Task

Scan all repo clones under ~/src/ (1-2 levels deep) and standardize their JSONL configuration.

### Step 1: Find all beads-enabled repos

```bash
# Find all directories named 'beads' at levels 1-2 under ~/src/
find ~/src -maxdepth 2 -type d -name beads
```

### Step 2: For each repo found, check configuration

For each directory from Step 1, check:
- Does `.beads/metadata.json` exist?
- What is the `jsonl_export` value?
- What JSONL files actually exist in `.beads/`?
- Are there multiple JSONL files (problem!)?

### Step 3: Create audit report

Generate a report showing:
```
Repo Path                           | Config        | Actual Files           | Status
----------------------------------- | ------------- | ---------------------- | --------
~/src/beads                         | beads.jsonl   | beads.jsonl            | OK
~/src/dave/beads                    | issues.jsonl  | issues.jsonl           | MISMATCH
~/src/emma/beads                    | issues.jsonl  | issues.jsonl, beads.jsonl | DUPLICATE!
```

### Step 4: Determine canonical name for each repo

For repos that are the SAME git repository (check `git remote -v`):
- Group them together
- Determine which JSONL filename should be canonical (majority wins, or beads.jsonl for the beads repo itself)
- List which clones need to be updated

### Step 5: Generate fix script

Create a script that for each mismatched clone:
1. Updates `.beads/metadata.json` to use the canonical name
2. If JSONL file needs renaming: `git mv .beads/old.jsonl .beads/new.jsonl`
3. Removes any duplicate JSONL files: `git rm .beads/duplicate.jsonl`
4. Commits the change
5. Syncs: `bd sync`

### Expected Output

1. Audit report showing all repos and their config status
2. List of repos grouped by git remote (same repository)
3. Fix script or manual instructions for standardizing each repo
4. Verification that after fixes, all clones of the same repo use the same JSONL filename

### Edge Cases

- Handle repos without metadata.json (use default discovery)
- Handle repos with no git remote (standalone/local)
- Handle repos that are not git repositories
- Don't modify repos with uncommitted changes (warn instead)

### Success Criteria

- All clones of the same git repository use the same JSONL filename
- No duplicate JSONL files in any repo
- All configurations documented in metadata.json
- bd doctor passes on all repos

## Session 1 Progress (2025-11-23)

**Completed**:
✅ Comprehensive audit of all 17 beads-enabled repos
✅ Created automated fix script (~/fix_beads_jsonl_v2.sh)
✅ Generated detailed audit report (~/beads_jsonl_audit_report.md)
✅ Successfully fixed 3 repos (secret/beads, dave/vc, fred/vc)

**Findings**:
- 11/17 repos (65%) had issues: duplicates, mismatches, or missing config
- 4 distinct git repositories with multiple clones each
- beads.git: 8 clones, canonical=beads.jsonl
- vc.git: 5 clones, canonical=issues.jsonl
- wyvern.git: 3 clones, canonical=issues.jsonl
- efrit.git: 1 clone (perfect, no issues!)

**Challenges**:
- 7 repos had uncommitted changes (skipped for safety)
- 2 repos hit merge conflicts when pushing (demonstrates the problem!)
- Active development ongoing in many clones

**Next Session**:
1. Resolve merge conflicts in secret/beads and secret/vc
2. Coordinate with active repos to commit/stash work
3. Re-run fix script on remaining 11 repos
4. Verify all fixes with re-audit
5. Consider pre-commit hook to prevent future drift

**Artifacts**:
- ~/beads_jsonl_audit_report.md - Detailed findings
- ~/beads_jsonl_fix_summary.md - Session summary
- ~/fix_beads_jsonl_v2.sh - Automated fix script
- /tmp/audit_beads_repos.sh - Re-runnable audit


Document code review findings for bd-0a43 refactoring

Code review completed successfully with minor suggestions for future improvements


Configure database connection pool limits for daemon mode

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

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

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

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

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

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

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

Effort: 1 hour


Add #nosec G304 comments to JSONL file reads in sync.go

sync.go:610 uses os.ReadFile(jsonlPath) without #nosec comment, inconsistent with other JSONL reads that have '// #nosec G304 - controlled path'.

Add comment for consistency with integrity.go:43 and import.go:316.


Rename last_import_hash metadata key to jsonl_content_hash

The metadata key 'last_import_hash' is misleading because it's updated on both import AND export (sync.go:614, import.go:320).

Better names:
- jsonl_content_hash (more accurate)
- last_sync_hash (clearer intent)

This is a breaking change requiring migration of existing metadata values.


Implement global N-way collision resolution algorithm

## Overview
Phase 3: Replace pairwise collision resolution with global N-way resolution that produces deterministic results regardless of sync order.

## Current Problem
ScoreCollisions (collision.go:228) compares issues pairwise:
```go
collision.RemapIncoming = existingHash < incomingHash
```

This works for 2-way but fails for 3+ way because:
- Each clone makes local decisions without global context
- No guarantee intermediate states are consistent
- Remapping decisions depend on sync order
- Can't detect transitive remap chains (test-1 → test-2 → test-3)

## Solution
Implement global resolution that:
1. Collects ALL versions of same logical issue
2. Sorts by content hash (deterministic)
3. Assigns sequential IDs based on sorted order
4. All clones converge to same assignments

## Implementation Tasks

### 1. Create ResolveNWayCollisions function
File: internal/storage/sqlite/collision.go

Replace ScoreCollisions with:
```go
// ResolveNWayCollisions handles N-way collisions deterministically.
// Groups all versions with same base ID, sorts by content hash,
// assigns sequential IDs. Returns mapping of old ID → new ID.
func ResolveNWayCollisions(ctx context.Context, s *SQLiteStorage,
    collisions []*CollisionDetail, incoming []*types.Issue) (map[string]string, error) {

    if len(collisions) == 0 {
        return make(map[string]string), nil
    }

    // Group by base ID pattern (e.g., test-1, test-2 → base "test-1")
    groups := groupCollisionsByBaseID(collisions)

    idMapping := make(map[string]string)

    for baseID, versions := range groups {
        // 1. Collect all unique versions by content hash
        uniqueVersions := deduplicateVersionsByContentHash(versions)

        // 2. Sort by content hash (deterministic!)
        sort.Slice(uniqueVersions, func(i, j int) bool {
            return uniqueVersions[i].ContentHash < uniqueVersions[j].ContentHash
        })

        // 3. Assign sequential IDs based on sorted order
        prefix := extractPrefix(baseID)
        baseNum := extractNumber(baseID)

        for i, version := range uniqueVersions {
            targetID := fmt.Sprintf("%s-%d", prefix, baseNum+i)

            // Map this version to its deterministic ID
            if version.ID != targetID {
                idMapping[version.ID] = targetID
            }
        }
    }

    return idMapping, nil
}
```

### 2. Implement helper functions

```go
// groupCollisionsByBaseID groups collisions by their logical base ID
func groupCollisionsByBaseID(collisions []*CollisionDetail) map[string][]*types.Issue {
    groups := make(map[string][]*types.Issue)
    for _, c := range collisions {
        baseID := c.ID  // All share same ID (that's why they collide)
        groups[baseID] = append(groups[baseID], c.ExistingIssue, c.IncomingIssue)
    }
    return groups
}

// deduplicateVersionsByContentHash keeps one issue per unique content hash
func deduplicateVersionsByContentHash(issues []*types.Issue) []*types.Issue {
    seen := make(map[string]*types.Issue)
    for _, issue := range issues {
        if _, found := seen[issue.ContentHash]; !found {
            seen[issue.ContentHash] = issue
        }
    }
    result := make([]*types.Issue, 0, len(seen))
    for _, issue := range seen {
        result = append(result, issue)
    }
    return result
}
```

### 3. Update handleCollisions in importer
File: internal/importer/importer.go

Replace ScoreCollisions call with:
```go
// OLD:
if err := sqlite.ScoreCollisions(ctx, sqliteStore, collisionResult.Collisions, allExistingIssues); err != nil {
    return nil, fmt.Errorf("failed to score collisions: %w", err)
}

// NEW:
idMapping, err := sqlite.ResolveNWayCollisions(ctx, sqliteStore,
    collisionResult.Collisions, issues)
if err != nil {
    return nil, fmt.Errorf("failed to resolve collisions: %w", err)
}
```

### 4. Update RemapCollisions
RemapCollisions currently uses collision.RemapIncoming field. Update to use idMapping directly:
- Remove RemapIncoming logic
- Use idMapping to determine what to remap
- Simplify to just apply the computed mapping

### 5. Add comprehensive tests

Test cases:
1. 3-way collision with different content → 3 sequential IDs
2. 3-way collision with 2 identical content → 2 IDs (dedupe works)
3. Sync order independence (A→B→C vs C→A→B produce same result)
4. Content hash ordering is respected
5. Works with 5+ clones

## Acceptance Criteria
- ResolveNWayCollisions implemented and replaces ScoreCollisions
- Groups all versions of same ID together
- Deduplicates by content hash
- Sorts by content hash deterministically
- Assigns sequential IDs starting from base ID
- Returns complete mapping (old ID → new ID)
- All clones converge to same ID assignments
- Works for arbitrary N-way collisions
- TestThreeCloneCollision passes (or gets much closer)

## Files to Modify
- internal/storage/sqlite/collision.go (new function, helpers)
- internal/importer/importer.go (call new function)
- internal/storage/sqlite/collision_test.go (comprehensive tests)

## Testing Strategy

### Unit Tests
- groupCollisionsByBaseID correctly groups
- deduplicateVersionsByContentHash removes duplicates
- Sorting by hash is stable and deterministic
- Sequential ID assignment is correct

### Integration Tests
- 3-way collision resolves to 3 issues
- Sync order doesn't affect final IDs
- Content hash ordering determines winner

### Property Tests
- For any N clones with same content, all converge to same IDs
- Idempotent: running resolution twice produces same result

## Dependencies
- Requires bd-cbed9619.5 (ContentHash field) to be completed first
- Requires bd-cbed9619.4 (read-only detection) for clean integration

## Notes
This is the core algorithm that enables convergence. The key insight:
**Sort by content hash globally, not pairwise comparison.**

Add tests for daemon sync module


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`


Refactor path canonicalization into helper function

The path canonicalization logic (filepath.Abs + EvalSymlinks) is duplicated in 3 places:
- beads.go:131-137 (BEADS_DIR handling)
- cmd/bd/main.go:446-451 (--no-db cleanup)
- cmd/bd/nodb.go:26-31 (--no-db initialization)

Refactoring suggestion:
Extract to a helper function like:
  func canonicalizePath(path string) string

This would:
- Reduce code duplication
- Make the logic easier to maintain
- Ensure consistent behavior across all path handling

Related to bd-e16b implementation.


Run final validation and cleanup checks

Final validation pass to ensure all cleanup objectives met and no regressions introduced.

Validation checklist:
1. Dead code verification: `go run golang.org/x/tools/cmd/deadcode@latest -test ./...`
2. Test coverage: `go test -cover ./...`
3. Build verification: `go build ./cmd/bd/`
4. Linting: `golangci-lint run`
5. Integration tests

Measure git operation reduction

Quantify the reduction in git operations (pulls, commits, pushes) when using Agent Mail for coordination.

Acceptance Criteria:
- Baseline: count git ops for 10 issues without Agent Mail
- With Agent Mail: count git ops for 10 issues
- Document reduction percentage
- Verify 70-80% reduction claim
- Measure impact on .git directory size growth

Success Metric: ≥70% reduction in git operations


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.

Test added to daemon_test.go as TestMutationToExportLatency().

Currently skipped with note that it should be enabled once bd-146 (event-driven daemon) is fully implemented and enabled by default.

The test structure is complete:
1. Sets up test environment with fast debounce (500ms)
2. SingleMutationLatency: measures latency from mutation to JSONL update
3. RapidMutationBatching: verifies multiple mutations batch into single export

Once event-driven mode is default, remove the t.Skip() line and the test will validate <500ms latency.

## Validation
- bd.wasm compiles successfully
- Can load in Node.js without errors
- Bundle size <10MB


Implement content-hash based collision resolution for deterministic convergence

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

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

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

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


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.


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

Phase 3: Enhance daemon robustness for GH #353

Improve daemon health checks and metadata refresh to prevent staleness issues.

**Tasks:**
1. Enhance daemon health checks to detect unreachable daemons
2. Add daemon metadata refresh (check disk every 5s)
3. Comprehensive testing in sandbox environments

**Implementation:**
- cmd/bd/main.go: Better health check error handling (lines 300-367)
- cmd/bd/daemon_event_loop.go: Periodic metadata refresh
- cmd/bd/daemon_unix.go: Permission-aware process checks

**References:**
- docs/GH353_INVESTIGATION.md (Solutions 4 & 5, lines 161-209)
- Depends on: Phase 2 (bd-u3t)

**Acceptance Criteria:**
- Daemon detects when it's unreachable and auto-switches to direct mode
- Daemon picks up external import operations without restart
- All edge cases handled gracefully


Add integration tests for multi-repo sync

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