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.


Fix multi-round convergence for N-way collisions

**Summary:** Multi-round collision resolution was identified as a critical issue preventing complete synchronization across distributed clones. The problem stemmed from incomplete final pulls that didn't fully propagate all changes between system instances.

**Key Decisions:**
- Implement multi-round sync mechanism
- Ensure bounded convergence (≤N rounds)
- Guarantee idempotent import without data loss

**Resolution:** Developed a sync strategy that ensures all clones converge to the same complete set of issues, unblocking the bd-cbed9619 epic and improving distributed system reliability.


GH#483: Pre-commit hook fails unnecessarily when .beads removed

Pre-commit hook fails on bd sync when .beads directory exists but user is on branch without beads. Should exit gracefully. See GitHub issue #483.


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?

Optimize --sandbox mode: skip FlushManager

When `--sandbox` mode is enabled, skip FlushManager creation entirely.

## Current Behavior
`main.go:561` always creates FlushManager:
```go
flushManager = NewFlushManager(autoFlushEnabled, getDebounceDuration())
```

Even with `--sandbox` (which sets `noAutoFlush=true`), the FlushManager goroutine is still running.

## Proposed Change
```go
// Only create FlushManager if we might actually need it
if !sandboxMode && autoFlushEnabled {
    flushManager = NewFlushManager(true, getDebounceDuration())
}
```

## Handle nil FlushManager
Update PersistentPostRun to handle nil:
```go
if flushManager != nil && !skipFinalFlush {
    if err := flushManager.Shutdown(); err != nil {
        // ...
    }
}
```

## Synchronous Export Fallback
When sandbox mode + write operation occurs, do synchronous export:
```go
if sandboxMode && isDirty {
    performSynchronousExport()
}
```

## Also: Default lock-timeout to 100ms in sandbox mode
In PersistentPreRun, when sandboxMode is detected:
```go
if sandboxMode {
    noDaemon = true
    noAutoFlush = true
    noAutoImport = true
    if lockTimeout == 30*time.Second { // Not explicitly set
        lockTimeout = 100 * time.Millisecond
    }
}
```

bd message: Improve type safety with typed parameter structs


bd export should verify JSONL line count matches database count

After export completes, bd should verify that the JSONL file line count matches the number of issues exported. This would catch silent failures where the export appears to succeed but doesn't actually write all issues.

Real-world scenario from VC project:
- Ran direct SQL DELETE to remove 240 issues
- Ran 'bd export -o .beads/issues.jsonl'
- No error shown, appeared to succeed
- But JSONL file was not updated (still had old line count)
- Later session found all 240 issues still in JSONL
- Had to repeat the cleanup

If export had verified line count, it would have immediately shown:
  Error: Export verification failed
    Expected: 276 issues
    JSONL file: 516 lines
    Mismatch indicates export failed to write all issues

This is especially important because:
1. JSONL is source of truth in git
2. Silent export failures cause data inconsistency
3. Users assume export succeeded if no error shown
4. The verification is cheap (just count lines)

Implementation:
- After writing JSONL, count lines in file
- Compare to len(exportedIDs)
- If mismatch, remove temp file and return error
- Show clear error message with both counts


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

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

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

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

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

## Potential Followups
See linked issues for suggestions.

BG's issue to reopen


Don't search parent directories for .beads databases

bd currently walks up the directory tree looking for .beads directories, which can find unrelated databases (e.g., ~/.beads). This causes confusing warnings and potential data pollution.

Should either:
1. Stop at git root (don't search above it)
2. Only use explicit BEADS_DB env var or local .beads
3. At minimum, don't search in home directory


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

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

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

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

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


Git history fallback doesn't escape regex special chars in IDs

## Problem

In `batchCheckGitHistory`, IDs are directly interpolated into a regex pattern:

```go
patterns = append(patterns, fmt.Sprintf(\`"id":"%s"\`, id))
searchPattern := strings.Join(patterns, "|")
cmd := exec.Command("git", "log", "--all", "-G", searchPattern, ...)
```

If an ID contains regex special characters (e.g., `bd-foo.bar` or `bd-test+1`), the pattern will be malformed or match unintended strings.

## Location
`internal/importer/importer.go:923-926`

## Impact
- False positives: IDs with `.` could match any character
- Regex errors: IDs with `[` or `(` could cause git to fail
- Security: potential for regex injection (low risk since IDs are validated)

## Fix
Escape regex special characters:

```go
import "regexp"

escapedID := regexp.QuoteMeta(id)
patterns = append(patterns, fmt.Sprintf(\`"id":"%s"\`, escapedID))
```


Audit Current Cache Usage

Understand exactly what code depends on the storage cache

Audit complete. See CACHE_AUDIT.md for full findings.

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


Optimize 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.


Create WASM build infrastructure (Makefile, scripts)

Set up build tooling for WASM compilation:

- Copy wasm_exec.js from Go distribution
- Create wrapper script for Node.js execution
- Add build task to Makefile or build script


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).


Implement hash ID generation in CreateIssue

Replace sequential ID generation with hash-based IDs in CreateIssue function.

## Current Behavior (internal/storage/sqlite/sqlite.go)
```go
func (s *SQLiteStorage) CreateIssue(ctx context.Context, issue *types.Issue) error {
    // ID comes from auto-increment counter
    // Collisions possible across clones
}
```

## New Behavior
```go
func (s *SQLiteStorage) CreateIssue(ctx context.Context, issue *types.Issue) error {
    // Generate hash ID if not provided
    if issue.ID == "" {
        issue.ID = idgen.GenerateHashID(
            issue.Title,
            issue.Description,
            time.Now(),
            s.workspaceID,
        )
    }

    // Assign next alias
    issue.Alias = s.getNextAlias()

    // Insert with hash ID + alias
    // ...
}
```

## Workspace ID Generation
Add to database initialization:
```go
// Generate stable workspace ID (persisted in .beads/workspace_id)
workspaceID := getOrCreateWorkspaceID()
```

Options for workspace ID:
1. Hostname + random suffix
2. UUID (random)
3. Git remote URL hash (deterministic per repo)

Recommended: Option 3 (git remote hash) for reproducibility

## Hash Collision Detection
```go
// On insert, check for collision (unlikely but possible)
existing, err := s.GetIssue(ctx, issue.ID)
if err == nil {
    // Hash collision! Add random suffix and retry
    issue.ID = issue.ID + "-" + randomSuffix(4)
}
```

## Files to Create/Modify
- internal/types/id_generator.go (new)
- internal/storage/sqlite/sqlite.go (CreateIssue)
- internal/storage/sqlite/workspace.go (new - workspace ID management)
- .beads/workspace_id (new file, git-ignored)

## Testing
- Test hash ID generation is deterministic
- Test collision detection and retry
- Test workspace ID persistence
- Benchmark: hash generation performance (<1μs)


Issue to close


Add error handling guidance for export metadata update failures

## Problem
The bd-ymj fix treats all metadata update failures as warnings:

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

But if metadata updates fail, the NEXT export will fail with "JSONL content has changed since last import".

## Questions
1. Should metadata failures be critical (return error)?
2. Should we implement retry logic?
3. Is warning acceptable (safe, just requires import before next export)?

## Current Behavior
- Metadata failure is silent (only logged)
- User won't know until next export fails
- Next export requires import first (safe but annoying)

## Recommendation
Add clear comment explaining the trade-off:

```go
// Note: Metadata update failures are treated as warnings, not errors.
// This is acceptable because the worst case is the next export will
// require an import first, which is safe and prevents data loss.
// Alternative: Make this critical and fail the export if metadata
// updates fail (but this makes exports more fragile).
if err := store.SetMetadata(ctx, "last_import_hash", currentHash); err != nil {
    log.log("Warning: failed to update last_import_hash: %v", err)
    log.log("Next export may require running 'bd import' first")
}
```

Extract duplicated validation logic from CLI commands

~150 lines of identical validation logic duplicated between cmd_create.go and cmd_update.go

Duplication found:
- validateBeadFields(): 2 identical copies (50+ lines each)
- parseTimeWithDefault(): 2 identical copies (30 lines each)
- Flag definitions: 15+ duplicate registrations

Solution: Extract to shared packages:

Add 'town report' command for aggregated swarm status

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

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

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

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

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

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

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


Debug MCP Agent Mail tool execution errors

**EXTERNAL WORK**: Debug the standalone MCP Agent Mail server (separate from beads integration).

The Agent Mail server runs as an independent service at ~/src/mcp_agent_mail. This is NOT beads code - it's a separate GitHub project we're evaluating for optional coordination features.

Current Issue:
- MCP API endpoint returns errors when calling ensure_project tool
- Error: "Server encountered an unexpected error while executing tool"
- Core HTTP server works, web UI functional, but tool wrapper layer fails

Server Details:
- Location: ~/src/mcp_agent_mail (separate repo)
- Repository: https://github.com/Dicklesworthstone/mcp_agent_mail
- Runs on: http://127.0.0.1:8765
- Bearer token: In .env file

Investigation Steps:
1. Check tool execution logs for full stack trace
2. Verify Git storage initialization at ~/.mcp_agent_mail_git_mailbox_repo
3. Review database setup (storage.sqlite3)
4. Test with simpler MCP tools if available
5. Compare with working test cases in tests/

Why This Matters:
- Blocks [deleted:bd-6hji] (testing file reservations)
- Need working MCP API to validate Agent Mail benefits
- Proof of concept for lightweight beads integration later

Note: The actual beads integration (bd-wfmw) will be lightweight HTTP client code only.


Fix revive style issues (78 issues)

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

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

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


Update AGENTS.md with event-driven mode

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

Centralize BD_DEBUG logging into debug package

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

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

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

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

Impact: Removes 43 scattered checks, improves code clarity

Refactor sqlite.go (2298 lines)

Break down internal/storage/sqlite/sqlite.go into smaller, more focused modules. The file is currently 2298 lines and should be split into logical components.


Time-dependent tests may be flaky near TTL boundary

Several tombstone merge tests use time.Now() to create test data: time.Now().Add(-24 * time.Hour), time.Now().Add(-60 * 24 * time.Hour), etc. While these work reliably in practice (24h vs 30d TTL has large margin), they could theoretically be flaky if: 1) Tests run slowly, 2) System clock changes during test, 3) TTL constants change. Recommendation: Consider using a fixed reference time or time injection for deterministic tests. Lower priority since current margin is large. Files: internal/merge/merge_test.go:1337-1338, 1352-1353, 1548-1549, 1590-1591


Doctor should exclude merge artifacts from 'multiple JSONL' warning

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


Convert magic numbers to named constants in FlushManager


Auto-import runs during --no-auto-import operations via stats/ready commands

Even when using --no-auto-import flag, certain commands like 'bd stats' and 'bd ready' still trigger auto-import internally, which can cause the git history backfill bug to corrupt data.

Example:
  bd stats --no-auto-import
  # Still prints 'Purged bd-xxx (recovered from git history...)'

The flag should completely disable auto-import for the command, but it appears some code paths still trigger it.

Workaround: Use --allow-stale instead, or --sandbox mode.


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

Test parent issue


Add content-addressable identity to Issue type

**Summary:** Added content-addressable identity to Issue type by implementing a ContentHash field that generates a unique SHA256 fingerprint based on semantic issue content. This resolves issue identification challenges when multiple system instances create issues with identical IDs but different contents.

**Key Decisions:**
- Use SHA256 for content hashing
- Hash excludes ID and timestamps
- Compute hash automatically at creation/import time
- Add database column for hash storage

**Resolution:** Successfully implemented a deterministic content hashing mechanism that enables reliable issue identification across distributed systems, improving data integrity and collision detection.


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

Standardize error handling: replace direct fmt.Fprintf+os.Exit with FatalError

Code health review found inconsistent error handling patterns:

Pattern A (preferred): FatalError() from errors.go:21-24
Pattern B (inconsistent): Direct fmt.Fprintf(os.Stderr) + os.Exit(1)

Affected files:
- delete.go:35-49 uses direct pattern
- create.go:213 ignores error silently
- Various other commands

Fix: Standardize on FatalError() wrapper for consistent error messages and testability.


Prevent multiple daemons from running on the same repo

Multiple bd daemons running on the same repo clone causes race conditions and data corruption risks.

**Problem:**
- Nothing prevents spawning multiple daemons for the same repository
- Multiple daemons watching the same files can conflict during sync operations
- Observed: 4 daemons running simultaneously caused sync race condition

**Solution:**
Implement daemon singleton enforcement per repo:
1. Use a lock file (e.g., .beads/.daemon.lock) with PID
2. On daemon start, check if lock exists and process is alive
3. If stale lock (dead PID), clean up and acquire lock
4. If active daemon exists, either:
   - Exit with message 'daemon already running (PID xxx)'
   - Or offer --replace flag to kill existing and take over
5. Release lock on graceful shutdown

**Edge cases to handle:**
- Daemon crashes without releasing lock (stale PID detection)
- Multiple repos in same directory tree (each repo gets own lock)
- Race between two daemons starting simultaneously (atomic lock acquisition)


Modify EnsureIDs to support parent resurrection

Update internal/storage/sqlite/ids.go:189-202 to call TryResurrectParent before failing on missing parent. Add resurrection mode flag, log resurrected parents for transparency. Maintain backwards compatibility with strict validation mode.


Issue 1 to reopen


Code Review Sweep: thorough

Perform thorough code review sweep based on accumulated activity.

**AI Reasoning:**
Significant code volume added (150,273 lines) across multiple critical areas, including cmd/bd, internal/storage/sqlite, and internal/rpc. High file change count (616) indicates substantial refactoring or new functionality. The metrics suggest potential for subtle architectural or implementation issues that warrant review.

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

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

File discovered issues with detailed reasoning and suggestions.


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._


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.


Document 3-clone ID non-determinism in collision resolution

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

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

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


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


Add Claude setup tip with dynamic priority

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


Add tests for daemon vs non-daemon parity in list filters

After bd-o43 RPC integration, we need tests to verify daemon mode behaves identically to direct mode for all new filter flags.

Test coverage needed:
- Pattern matching: --title-contains, --desc-contains, --notes-contains
- Date ranges: all 6 date filter flags (created/updated/closed after/before)
- Empty/null checks: --empty-description, --no-assignee, --no-labels
- Priority ranges: --priority-min, --priority-max
- Status normalization: --status all vs no status flag
- Date parsing: YYYY-MM-DD, RFC3339, and error cases
- Backward compat: deprecated --label flag still works

Oracle review findings (bd-o43):
- Date parsing should support multiple formats
- Status 'all' should be treated as unset
- NoLabels field was missing from RPC protocol
- Error messages should be clear and actionable

Test approach:
- Create RPC integration tests in internal/rpc/server_issues_epics_test.go
- Compare daemon client.List() vs direct store.SearchIssues() for same filters
- Verify error messages match between modes
- Test with real daemon instance, not just unit tests


Code Health Review Dec 2025: Technical Debt Cleanup

Epic grouping technical debt identified in the Dec 16, 2025 code health review.

## Overall Health Grade: B (Solid foundation, needs cleanup)

### P1 (High Priority):
- bd-74w1: Consolidate duplicate path-finding utilities
- bd-b6xo: Remove/fix ClearDirtyIssues() race condition
- bd-b3og: Fix TestImportBugIntegration deadlock

### P2 (Medium Priority):
- bd-05a8: Split large files (doctor.go, sync.go)
- bd-qioh: Standardize error handling patterns
- bd-rgyd: Split queries.go (1586 lines)
- bd-9g1z: Fix/remove TestFindJSONLPathDefault

### P3 (Low Priority):
- bd-ork0: Add comments to 30+ ignored errors
- bd-4nqq: Remove dead test code in info_test.go
- bd-dhza: Reduce global state in main.go

## Key Areas:
1. Code duplication in path utilities
2. Large monolithic files (5 files >1000 lines)
3. Global state (25+ variables, 3 deprecated)
4. Silent error suppression (30+ instances)
5. Test gaps and dead test code
6. Atomicity risks in batch operations


Document bd edit command and verify MCP exclusion

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


GH#497: bd onboard copilot-instructions.md is beads-specific, not generic

bd onboard outputs beads repo specific content (Go/SQLite/Cobra) for copilot-instructions.md instead of a generic template. AGENTS.md output is correct. See: https://github.com/steveyegge/beads/issues/497


Test hook


Extract daemon config functions to daemon_config.go


Integrate beads-merge tool by @neongreen

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

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

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

**Integration options**:

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

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

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

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

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

Next: Wait for response before proceeding with integration.

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

Next: Vendor beads-merge with full attribution


Add edge case tests for GetNextChildID parent resurrection

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

## Missing Test Cases

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

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

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

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

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

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

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

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


CLI tests (cli_fast_test.go) are slow and should be integration tests

The TestCLI_* tests in cmd/bd/cli_fast_test.go are taking 4-5 seconds each (40+ seconds total), making them the slowest part of the fast test suite.

Current timings:
- TestCLI_Import: 4.73s
- TestCLI_Blocked: 4.33s
- TestCLI_DepTree: 4.15s
- TestCLI_Close: 3.59s
- TestCLI_DepAdd: 3.50s
- etc.

These tests compile the bd binary once in init(), but then execute it multiple times per test with filesystem operations. Despite being named "fast", they're actually end-to-end CLI integration tests.

Options:
1. Tag with //go:build integration (move to integration suite)
2. Optimize: Use in-memory databases, reduce exec calls, better parallelization
3. Keep as-is but understand they're the baseline for "fast" tests

Total test suite currently: 13.8s (cmd/bd alone is 12.8s, and most of that is these CLI tests)

Fixed by reusing existing bd binary from repo root instead of rebuilding.

Before: 15+ minutes (rebuilding binary for every test package)
After: ~12 seconds (reuses pre-built binary)

The init() function now checks for ../../bd first before falling back to building. This means `go build && go test` is now fast.


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


Investigate database pollution - issue count anomalies

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

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

Investigation findings:

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

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

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

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

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


Rapid 2


Create examples for common workflows

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


Clarify .beads/.gitattributes handling in Protected Branches docs

Protected Branches docs quick start leaves untracked `.beads` directory and `.gitattributes`.
Question: Are these changes meant to be checked into the protected branch?
Need to clarify if these should be ignored or committed, or if the instructions are missing a step.


Cleanup: --ephemeral flag

Update bd cleanup to handle ephemeral issues.

New flag:
- bd cleanup --ephemeral - deletes all CLOSED issues with ephemeral=true

Behavior:
- Only deletes if status=closed AND ephemeral=true
- Respects --dry-run flag
- Reports count of deleted ephemeral issues

This allows swarm cleanup to remove transient messages without affecting permanent issues.


Export doesn't update last_import_hash metadata causing perpetual 'JSONL content has changed' errors

After a successful export, the daemon doesn't update last_import_hash or last_import_mtime metadata. This causes hasJSONLChanged to return true on the next export attempt, blocking with 'refusing to export: JSONL content has changed since last import'.

Related to GH #334.

Scenario:
1. Daemon exports successfully → JSONL updated, hash changes
2. Metadata NOT updated (last_import_hash still points to old hash)
3. Next mutation triggers export
4. validatePreExport calls hasJSONLChanged
5. hasJSONLChanged sees current JSONL hash != last_import_hash
6. Export blocked with 'JSONL content has changed since last import'
7. Issue stuck: can't export, can't make progress

This creates a catch-22 where the system thinks JSONL changed externally when it was the daemon itself that changed it.

Current behavior:
- Import updates metadata (import.go:310-336)
- Export does NOT update metadata (daemon_sync.go:307)
- Result: metadata becomes stale after every export


Test FK constraint via close


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)


Consider consolidating config.yaml parsing into shared utility

Multiple places parse config.yaml with custom structs:

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

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

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

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

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

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


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.


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

Polecats get stuck on interactive shell prompts (cp/mv/rm -i)

During swarm operations, polecats frequently get stuck waiting for interactive prompts from shell commands like:
- cp prompting 'overwrite file? (y/n)'
- mv prompting 'overwrite file? (y/n)'
- rm prompting 'remove file?'

This happens because macOS aliases or shell configs may have -i flags set by default.

Root cause: Claude Code runs commands that trigger interactive confirmation prompts, but cannot respond to them, causing the agent to hang indefinitely.

Observed in: Multiple polecats during GH issues swarm (Dec 2024)
- Derrick, Roustabout, Prospector, Warboy all got stuck on y/n prompts

Suggested fixes:
1. AGENTS.md should instruct agents to always use -f flag with cp/mv/rm
2. Polecat startup could set shell aliases to use non-interactive versions
3. bd prime hook could include guidance about non-interactive commands
4. Consider detecting stuck prompts and auto-recovering


Add TestNWayCollision for 5+ clones

## Overview
Add comprehensive tests for N-way (5+) collision resolution to verify the solution scales beyond 3 clones.

## Purpose
While TestThreeCloneCollision validates the basic N-way case, we need to verify:
1. Solution scales to arbitrary N
2. Performance is acceptable with more clones
3. Convergence time is bounded
4. No edge cases in larger collision groups

## Implementation Tasks

### 1. Create TestFiveCloneCollision
File: beads_twoclone_test.go (or new beads_nway_test.go)

```go
func TestFiveCloneCollision(t *testing.T) {
    // Test with 5 clones creating same ID with different content
    // Verify all 5 clones converge after sync rounds

    t.Run("SequentialSync", func(t *testing.T) {
        testNCloneCollision(t, 5, "A", "B", "C", "D", "E")
    })

    t.Run("ReverseSync", func(t *testing.T) {
        testNCloneCollision(t, 5, "E", "D", "C", "B", "A")
    })

    t.Run("RandomSync", func(t *testing.T) {
        testNCloneCollision(t, 5, "C", "A", "E", "B", "D")
    })
}
```

### 2. Implement generalized testNCloneCollision
Generalize the 3-clone test to handle arbitrary N:

```go
func testNCloneCollision(t *testing.T, numClones int, syncOrder ...string) {
    t.Helper()

    if len(syncOrder) != numClones {
        t.Fatalf("syncOrder length (%d) must match numClones (%d)",
            len(syncOrder), numClones)
    }

    tmpDir := t.TempDir()

    // Setup remote and N clones
    remoteDir := setupBareRepo(t, tmpDir)
    cloneDirs := make(map[string]string)

    for i := 0; i < numClones; i++ {
        name := string(rune('A' + i))
        cloneDirs[name] = setupClone(t, tmpDir, remoteDir, name)
    }

    // Each clone creates issue with same ID but different content
    for name, dir := range cloneDirs {
        createIssue(t, dir, fmt.Sprintf("Issue from clone %s", name))
    }

    // Sync in specified order
    for _, name := range syncOrder {
        syncClone(t, cloneDirs[name], name)
    }

    // Final pull for convergence
    for name, dir := range cloneDirs {
        finalPull(t, dir, name)
    }

    // Verify all clones have all N issues
    expectedTitles := make(map[string]bool)
    for i := 0; i < numClones; i++ {
        name := string(rune('A' + i))
        expectedTitles[fmt.Sprintf("Issue from clone %s", name)] = true
    }

    for name, dir := range cloneDirs {
        titles := getTitles(t, dir)
        if !compareTitleSets(titles, expectedTitles) {
            t.Errorf("Clone %s missing issues: expected %v, got %v",
                name, expectedTitles, titles)
        }
    }

    t.Log("✓ All", numClones, "clones converged successfully")
}
```

### 3. Add performance benchmarks
Test convergence time and memory usage:

```go
func BenchmarkNWayCollision(b *testing.B) {
    for _, n := range []int{3, 5, 10, 20} {
        b.Run(fmt.Sprintf("N=%d", n), func(b *testing.B) {
            for i := 0; i < b.N; i++ {
                // Run N-way collision and measure time
                testNCloneCollisionBench(b, n)
            }
        })
    }
}
```

### 4. Add convergence time tests
Verify bounded convergence:

```go
func TestConvergenceTime(t *testing.T) {
    // Test that convergence happens within expected rounds
    // For N clones, should converge in at most N-1 sync rounds

    for n := 3; n <= 10; n++ {
        t.Run(fmt.Sprintf("N=%d", n), func(t *testing.T) {
            rounds := measureConvergenceRounds(t, n)
            maxExpected := n - 1
            if rounds > maxExpected {
                t.Errorf("Convergence took %d rounds, expected ≤ %d",
                    rounds, maxExpected)
            }
        })
    }
}
```

### 5. Add edge case tests
Test boundary conditions:
- All N clones have identical content (dedup works)
- N-1 clones have same content, 1 differs
- All N clones have unique content
- Mix of collisions and non-collisions

## Acceptance Criteria
- TestFiveCloneCollision passes with all sync orders
- All 5 clones converge to identical content
- Performance is acceptable (< 5 seconds for 5 clones)
- Convergence time is bounded (≤ N-1 rounds)
- Edge cases handled correctly
- Benchmarks show scalability to 10+ clones

## Files to Create/Modify
- beads_twoclone_test.go or beads_nway_test.go
- Add helper functions for N-clone setup

## Testing Strategy

### Test Matrix
| N Clones | Sync Orders | Expected Result |
|----------|-------------|-----------------|
| 3        | A→B→C       | Pass            |
| 3        | C→B→A       | Pass            |
| 5        | A→B→C→D→E   | Pass            |
| 5        | E→D→C→B→A   | Pass            |
| 5        | Random      | Pass            |
| 10       | Sequential  | Pass            |

### Performance Targets
- 3 clones: < 2 seconds
- 5 clones: < 5 seconds
- 10 clones: < 15 seconds

## Dependencies
- Requires bd-cbed9619.5, bd-cbed9619.4, bd-0dcea000, bd-4d7fca8a to be completed
- TestThreeCloneCollision must pass first

## Success Metrics
- All tests pass for N ∈ {3, 5, 10}
- Convergence time scales linearly (O(N))
- Memory usage reasonable (< 100MB for 10 clones)
- No data corruption or loss in any scenario


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

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

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

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


Import overwrites newer local issues with older remote versions

## Problem

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

## What Happened

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

## Root Cause

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

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

Import applies incoming version regardless of which is newer.

## Expected Behavior

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

## Solution

Add timestamp checking to DetectCollisions or importIssues:

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

Improve internal/daemon test coverage (currently 22.5%)

Daemon functionality needs better coverage:
- Auto-start behavior
- Lock file management
- Discovery mechanisms
- Connection handling
- Error recovery

Current coverage: 58.3% (improved from 22.5% as of Nov 2025)

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

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


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().


Use stable repo identifiers instead of full paths in metadata keys

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

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

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

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

Import reports misleading '0 created, 0 updated' when actually importing all issues

When running 'bd import' on a fresh database (no existing issues), the command reports 'Import complete: 0 created, 0 updated' even though it successfully imported all issues from the JSONL file.

**Steps to reproduce:**
1. Delete .beads/beads.db
2. Run: bd import .beads/issues.jsonl
3. Observe output: 'Import complete: 0 created, 0 updated'
4. Run: bd list
5. Confirm: All issues are actually present in the database

**Expected behavior:**
Report the actual number of issues imported, e.g., 'Import complete: 523 created, 0 updated'

**Actual behavior:**
'Import complete: 0 created, 0 updated' (misleading - makes user think import failed)

**Impact:**
- Users think import failed when it succeeded
- Confusing during database sync operations (e.g., after git pull)
- Makes debugging harder (can't tell if import actually worked)

**Context:**
Discovered during VC session when syncing database after git pull. The misleading message caused confusion about whether the database was properly synced with the canonical JSONL file.


SearchIssues N+1 query causes context timeout with GetLabels

scanIssues() calls GetLabels in a loop for every issue, causing N+1 queries and context deadline exceeded errors when used with short timeouts or in-memory databases. This is especially problematic since SearchIssues already supports label filtering via SQL WHERE clauses.


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

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

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

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

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

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

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

This is CRITICAL - main should never have breaking tests.


Add unit tests for reset package

Comprehensive unit tests for internal/reset package.

## Test Cases

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

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

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

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

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

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

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


Code review follow-up for bd-dvd and bd-ymj fixes

Track improvements and issues identified during code review of parent resurrection (bd-dvd) and export metadata (bd-ymj) bug fixes.

## Context
Code review identified several areas for improvement:
- Code duplication in metadata updates
- Missing multi-repo support
- Test coverage gaps
- Potential race conditions

## Related Issues
Original bugs fixed: bd-dvd, bd-ymj

## Goals
- Eliminate code duplication
- Add multi-repo support where needed
- Improve test coverage
- Address edge cases


GH#523: Fix closed issues missing closed_at timestamp during db upgrade

Old beads databases may have closed issues without closed_at timestamps, causing 'closed issues must have closed_at timestamp' validation errors on upgrade to 0.29.0. Need defensive handling during import. See: https://github.com/steveyegge/beads/issues/523


Implement `bd setup cursor` for Cursor IDE integration

Create a `bd setup cursor` command that integrates Beads workflow into Cursor IDE via .cursorrules file. Unlike Claude Code (which has hooks), Cursor uses a static rules file to provide context to its AI.


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.


Refactor duplicate JSONL-from-git parsing code

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

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

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

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


Isolate RPC server startup into rpc_server.go

Create internal/daemonrunner/rpc_server.go with StartRPC function. Move startRPCServer logic here and return typed handle.


bd info shows 'auto_start_disabled' even when daemon is crashed/missing


Fix default .beads/.gitignore to ignore merge artifacts (GH #274)

Updated the default .gitignore template created by `bd init` to properly ignore merge artifacts and fix overly broad patterns.

Changes:
- Added `*.db?*` pattern for database files with query strings
- Added explicit patterns for merge artifacts: beads.{base,left,right}.{jsonl,meta.json}
- Changed `!*.jsonl` to `!issues.jsonl` to avoid including merge artifact JSONL files

This fixes GitHub issue #274 reported by rscorer.


Remove Storage Cache from Server Struct

Eliminate cache fields and use s.storage directly


Make DetectCollisions read-only (separate detection from modification)

**Summary:** The project restructured the collision detection process in the database to separate read-only detection from state modification, eliminating race conditions and improving system reliability. This was achieved by introducing a two-phase approach: first detecting potential collisions, then applying resolution separately.

**Key Decisions:**
- Create read-only DetectCollisions method
- Add RenameDetail to track potential issue renames
- Implement atomic ApplyCollisionResolution function
- Separate detection logic from database modification

**Resolution:** The refactoring creates a more robust, composable collision handling mechanism that prevents partial failures and maintains database consistency during complex issue import scenarios.

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.

Fix bd doctor to recommend issues.jsonl as canonical (not beads.jsonl)


Add multi-repo support to export metadata updates

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

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

But metadata updates are missing!

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

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

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

Improve test coverage for internal/beads (48.1% → 70%)

The beads package is a core package with 48.1% coverage. As the primary package for issue management, it should have at least 70% coverage.

Current coverage: 48.1%
Target coverage: 70%


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

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

## The Problem

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

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

## Proposed Behavior

```
$ bd init --prefix bd

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

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

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

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

Aborting.
```

## Trigger Conditions

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

## Edge Cases

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

## Related

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

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


Add error handling test for cmd.Help() in search command

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

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

In cmd/bd/search.go:39, the return value of cmd.Help() is not checked, flagged by errcheck linter.

Add test to verify:
- Error handling when cmd.Help() fails (e.g., output redirection fails)
- Proper error propagation to caller
- Command still exits gracefully on help error

This ensures the search command handles help errors properly and doesn't silently ignore failures.

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


Test SQLite WASM compatibility

- [ ] Test JSONL import/export
- [ ] Benchmark performance vs native

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


GH#509: bd fails to find .beads from nested worktrees

findDatabaseInTree stops at worktree git root, missing .beads in parent repo. Should check git-common-dir and search past worktree root. See: https://github.com/steveyegge/beads/issues/509


Git history fallback has incorrect logic for detecting deletions

## Problem

The `wasInGitHistory` function in `internal/importer/importer.go:891` returns true if the ID is found **anywhere** in git history. But finding an ID in history doesn't necessarily mean it was deleted - it could mean:

1. The issue was added (appears in a commit adding it)
2. The issue was modified (appears in commits updating it)
3. The issue was deleted (appears in a commit removing it)

The current logic incorrectly treats all three cases as 'deleted'.

## Correct Logic

`git log -S` with `--oneline` shows commits where the string was added OR removed. To detect deletion specifically:

1. ID appears in git history (was once in JSONL)
2. ID is NOT currently in JSONL

The second condition is already checked by the caller (`purgeDeletedIssues`), so technically the logic is correct in context. But the function name and doc comment are misleading.

## Fix Options

1. **Rename function** to `wasEverInJSONL` and update doc comment to clarify
2. **Add explicit check** for current JSONL state in the function itself

Option 1 is simpler and correct since caller already filters.

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

- Config migration for existing users

Estimated effort: 1-2 days


Fix FindBeadsDir to prioritize main repo .beads for worktrees

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

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

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

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

## Proposed Architecture

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

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

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

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

## Implementation Phases

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

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

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

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

## Risks & Mitigations

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

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

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

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

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

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

bd cleanup --hard should skip tombstone creation for true permanent deletion

## Problem

When using bd cleanup --hard --older-than N --force, the command:
1. Deletes closed issues older than N days (converting them to tombstones with NOW timestamp)
2. Then tries to prune tombstones older than N days (finds none because they were just created)

This leaves the database bloated with fresh tombstones that will not be pruned.

## Expected Behavior

In --hard mode, the deletion should be permanent without creating tombstones, since the user explicitly requested bypassing sync safety.

## Workaround

Manually delete from database: sqlite3 .beads/beads.db 'DELETE FROM issues WHERE status=tombstone'

## Fix Options

1. In --hard mode, use a different delete path that does not create tombstones
2. After deleting, immediately prune the just-created tombstones regardless of age
3. Pass a skip_tombstone flag to the delete operation

Option 1 is cleanest - --hard should mean permanent delete without tombstone.


Fix row iterator resource leak in recursive dependency queries

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

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

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

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

Impact: Connection exhaustion during dependency traversal

bd prime: Detect ephemeral branches and adjust workflow output

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

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

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

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

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

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


worktree: any bd command is slow

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


Testing & Validation

Ensure reliability through comprehensive testing.

Completed comprehensive Agent Mail test coverage analysis and implementation.

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

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

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

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

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

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


Improve bd doctor output formatting for better readability

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


Add transaction boundaries for export metadata updates

## Problem
Metadata updates happen after export, but there's no transaction ensuring atomicity between:
1. JSONL file write (exportToJSONLWithStore)
2. Metadata update (updateExportMetadata)
3. Database mtime update (TouchDatabaseFile)

If process crashes between these steps, metadata will be inconsistent.

## Example Failure Scenario
```
1. Export to JSONL succeeds
2. [CRASH] Process killed before metadata update
3. Next export: "JSONL content has changed" error
4. User must run import to fix metadata
```

## Options

### Option 1: Tolerate Inconsistency (Current)
- Simple, no code changes
- Safe (worst case: need import before next export)
- Annoying for users if crashes are frequent

### Option 2: Add Write-Ahead Log
- Write metadata intent to temp file
- Complete operations
- Clean up temp file
- More complex, better guarantees

### Option 3: Store Metadata in JSONL Comments
- Add metadata as JSON comment in JSONL file
- Single atomic write
- Requires JSONL format change

### Option 4: Defensive Checks
- On startup, verify metadata matches JSONL
- Auto-fix if mismatch detected
- Simplest improvement

## Recommendation
Start with Option 4 (defensive checks), consider others if needed.

## Files
- cmd/bd/daemon_sync.go
- Possibly: cmd/bd/main.go (startup checks)

## Related
This is lower priority - current behavior is safe, just not ideal

bd preflight: PR readiness checks for contributors

## Vision

Encode project-specific institutional knowledge into executable checks. CONTRIBUTING.md is documentation that's read once and forgotten; `bd preflight` is documentation that runs at exactly the right moment.

## Problem Statement

Contributors face a "last mile" problem - they do the work but stumble on project-specific gotchas at PR time:
- Nix vendorHash gets stale when go.sum changes
- Beads artifacts leak into PRs (see bd-umbf for namespace solution)
- Version mismatches between version.go and default.nix
- Tests/lint not run locally before pushing
- Other project-specific checks that only surface when CI fails

These are too obscure to remember, exist in docs nobody reads end-to-end, and waste CI round-trips.

## Why beads?

Beads already has a foothold in the contributor workflow. It knows:
- Git state (staged files, branch, dirty status)
- Project structure
- The specific issue being worked on
- Project-specific configuration

## Proposed Interface

### Tier 1: Checklist Mode (v1)

    $ bd preflight
    PR Readiness Checklist:

    [ ] Tests pass: go test -short ./...
    [ ] Lint passes: golangci-lint run ./...
    [ ] No beads pollution: check .beads/issues.jsonl diff
    [ ] Nix hash current: go.sum unchanged or vendorHash updated
    [ ] Version sync: version.go matches default.nix

    Run 'bd preflight --check' to validate automatically.

### Tier 2: Check Mode (v2)

    $ bd preflight --check
    ✓ Tests pass
    ✓ Lint passes
    ⚠ Beads pollution: 3 issues in diff - are these project issues or personal?
    ✗ Nix hash stale: go.sum changed, vendorHash needs update
      Fix: sha256-KRR6dXzsSw8OmEHGBEVDBOoIgfoZ2p0541T9ayjGHlI=
    ✓ Version sync

    1 error, 1 warning. Run 'bd preflight --fix' to auto-fix where possible.

### Tier 3: Fix Mode (v3)

    $ bd preflight --fix
    ✓ Updated vendorHash in default.nix
    ⚠ Cannot auto-fix beads pollution - manual review needed

## Checks to Implement

| Check | Description | Auto-fixable |
|-------|-------------|--------------|
| tests | Run go test -short ./... | No |
| lint | Run golangci-lint | Partial (gofmt) |
| beads-pollution | Detect personal issues in diff | No (see bd-umbf) |
| nix-hash | Detect stale vendorHash | Yes (if nix available) |
| version-sync | version.go matches default.nix | Yes |
| no-debug | No TODO/FIXME/console.log | Warn only |
| clean-stage | No unintended files staged | Warn only |

## Future: Configuration

Make checks configurable per-project via .beads/preflight.yaml:

    preflight:
      checks:
        - name: tests
          run: go test -short ./...
          required: true
        - name: no-secrets
          pattern: "**/*.env"
          staged: deny
        - name: custom-check
          run: ./scripts/validate.sh

This lets any project using beads define their own preflight checks.

## Implementation Phases

### Phase 1: Static Checklist
- Implement bd preflight with hardcoded checklist for beads
- No execution, just prints what to check
- Update CONTRIBUTING.md to reference it

### Phase 2: Automated Checks
- Implement bd preflight --check
- Run tests, lint, detect stale hashes
- Clear pass/fail/warn output

### Phase 3: Auto-fix
- Implement bd preflight --fix
- Fix vendorHash, version sync
- Integrate with bd-umbf solution for pollution

### Phase 4: Configuration
- .beads/preflight.yaml support
- Make it useful for other projects using beads
- Plugin/hook system for custom checks

## Dependencies

- bd-umbf: Namespace isolation for beads pollution (blocking for full solution)

## Success Metrics

- Fewer CI failures on first PR push
- Reduced "fix nix hash" commits
- Contributors report preflight caught issues before CI


Proposal: Custom status states via config

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

Examples:
- awaiting_verification
- awaiting_docs
- awaiting_testing


Add date and priority filters to bd search

Add filter parity with bd list for consistent querying.

**Missing filters to add:**
- --priority, --priority-min, --priority-max
- --created-after, --created-before
- --updated-after, --updated-before
- --closed-after, --closed-before
- --empty-description, --no-assignee, --no-labels
- --desc-contains, --notes-contains

**Files to modify:**
- cmd/bd/search.go
- internal/rpc/protocol.go (SearchArgs)
- internal/storage/storage.go (Search method)

**Testing:**
- All filter combinations
- Date format parsing
- Daemon and direct mode


Test issue 1


Consolidate check-health DB opens into single connection

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


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


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

Rename detection successfully implemented and tested!

**What was implemented:**
1. Content-hash based rename detection in DetectCollisions
2. When importing JSONL, if an issue has different ID but same content as DB issue, treat as rename
3. Delete old ID and accept new ID from JSONL
4. Added post-import re-export in sync command to flush rename changes
5. Added post-import commit to capture rename changes

**Test results:**
TestTwoCloneCollision now shows full convergence:
- Clone A: test-2="Issue from clone A", test-1="Issue from clone B"
- Clone B: test-1="Issue from clone B", test-2="Issue from clone A"

Both clones have **identical content** (titles match IDs correctly). Only timestamps differ (expected).

**What remains:**
- Test still expects exact JSON match including timestamps
- Could normalize timestamp comparison, but content convergence is the critical success metric
- The two-clone collision workflow now works without data corruption!


Implement global N-way collision resolution algorithm

**Summary:** Replaced pairwise collision resolution with a global N-way algorithm that deterministically resolves issue ID conflicts across multiple clones. The new approach groups collisions, deduplicates by content hash, and assigns sequential IDs to ensure consistent synchronization.

**Key Decisions:**
- Use content hash for global, stable sorting
- Group collisions by base ID
- Assign sequential IDs based on sorted unique versions
- Eliminate order-dependent remapping logic

**Resolution:** Implemented ResolveNWayCollisions function that guarantees deterministic issue ID assignment across multiple synchronization scenarios, solving the core challenge of maintaining consistency in distributed systems with potential conflicts.


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


Fix bd doctor --fix recursive message for deletions manifest

When running bd doctor --fix, if the deletions manifest check fails but there are no deleted issues in git history, the fix succeeds but doesn't create the file. The check then runs again and tells user to run bd doctor --fix - the same command they just ran.

Fix: Create empty deletions.jsonl when hydration finds no deletions, and recognize empty file as valid in the check.

Fixes: https://github.com/steveyegge/beads/issues/403


bd message: Refactor duplicated error messages


Perpetual 'JSONL file hash mismatch detected (bd-160)' warning

After cleanup operations, every bd command shows:
```
⚠  WARNING: JSONL file hash mismatch detected (bd-160)
  This indicates JSONL and export_hashes are out of sync.
  Clearing export_hashes to force full re-export.
```

The warning appears repeatedly even after the hash is supposedly cleared. This suggests either:
1. The clear isn't persisting
2. Something keeps causing the mismatch
3. The detection logic has a bug

**Impact:** Warning fatigue - users ignore it, may miss real issues.

**Expected behavior:** After clearing export_hashes once, subsequent operations should not show the warning unless there's a new mismatch.


Implement signal-aware context in CLI commands

Replace context.Background() with signal.NotifyContext() to enable graceful cancellation.

## Context
Part of context propagation work (bd-350). Phase 1 infrastructure is complete - sqlite.New() now accepts context parameter.

## Implementation
Set up signal-aware context at the CLI entry points:

```go
ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
defer cancel()
```

## Key Locations
- cmd/bd/main.go:438 (marked with TODO(bd-350))
- cmd/bd/daemon.go:317 (marked with TODO(bd-350))
- Other command entry points

## Benefits
- Ctrl+C cancels ongoing database operations
- Graceful shutdown on SIGTERM
- Better user experience during long operations

## Acceptance Criteria
- [ ] Ctrl+C during import cancels operation cleanly
- [ ] Ctrl+C during export cancels operation cleanly
- [ ] No database corruption on cancellation
- [ ] Proper cleanup on signal (defers execute)

Benchmark Helper Functions

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

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

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

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

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

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

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


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.
