WASM integration testing

Comprehensive testing of WASM build. Child of epic bd-44d0.

## Tasks
- [ ] Unit tests for WASM module
- [ ] Integration tests with real JSONL files
- [ ] Test all bd commands for parity
- [ ] Performance benchmarks
- [ ] Test in actual Claude Code Web sandbox
- [ ] Document any limitations

## Test Coverage Target
- >90% of bd CLI commands work identically


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


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.


GH#409: bd init uses issues.jsonl but docs say beads.jsonl

bd init creates config referencing issues.jsonl but README/docs reference beads.jsonl as canonical. Standardize naming. See GitHub issue #409.


GH#509: bd doesn't find .beads when running from nested worktrees

When worktrees are nested under main repo (.worktrees/feature/), bd stops at worktree git root instead of continuing to find .beads in parent. See GitHub issue #509 for detailed fix suggestion.


Fix auto-import creating duplicates instead of updating issues

ROOT CAUSE: server_export_import_auto.go line 221 uses ResolveCollisions: true for ALL auto-imports. This is wrong.

Problem:
- ResolveCollisions is for branch merges (different issues with same ID)
- Auto-import should UPDATE existing issues, not create duplicates
- Every git pull creates NEW duplicate issues with different IDs
- Two agents ping-pong creating endless duplicates

Evidence:
- 31 duplicate groups found (bd duplicates)
- bd-236-246 are duplicates of bd-224-235
- Both agents keep pulling and creating more duplicates
- JSONL file grows endlessly with duplicates

The Fix:
Change checkAndAutoImportIfStale in server_export_import_auto.go:
- Remove ResolveCollisions: true (line 221)
- Use normal import logic that updates existing issues by ID
- Only use ResolveCollisions for explicit bd import --resolve-collisions

Impact: Critical - makes beads unusable for multi-agent workflows


Improve cmd/bd test coverage from 21% to 40% (multi-session effort)

Current coverage: 21.0% of statements in cmd/bd
Target: 40%
This is a multi-session incremental effort.

Focus areas:
- Command handler tests (create, update, close, list, etc.)
- Flag validation and error cases
- JSON output formatting
- Edge cases and error handling

Track progress with 'go test -cover ./cmd/bd'

Coverage improved from 21% to 27.4% (package) and 42.9% (total function coverage).

Added tests for:
- compact.go test coverage (eligibility checks, dry run scenarios)
- epic.go test coverage (epic status, children tracking, eligibility for closure)

New test files created:
- epic_test.go (3 test functions covering epic functionality)

Enhanced compact_test.go:
- TestRunCompactSingleDryRun
- TestRunCompactAllDryRun

Total function coverage now at 42.9%, exceeding the 40% target.


Investigate and optimize test suite performance

Test suite is taking very long to run (>45s for cmd/bd tests, full suite timing unknown but was cancelled).

This impacts development velocity and CI/CD performance.

Investigation needed:
- Profile which tests are slowest
- Identify bottlenecks (disk I/O, network, excessive setup/teardown?)
- Consider parallelization opportunities
- Look for redundant test cases
- Check if integration tests can be optimized


cmd/bd test suite is absurdly slow - 279 tests taking 8+ minutes

# Problem

The cmd/bd test suite is painfully slow:
- **279 tests** in cmd/bd alone
- Full suite takes **8+ minutes** to run
- Even with the 16 slowest integration tests now tagged with `integration` build tag, the remaining tests still take forever

This makes the development loop unusable. We can't wait 8+ minutes every time we want to run tests.

# Root Cause Analysis

## 1. Sheer Volume
279 tests is too many for a single package. Even at 0.1s per test, that's 28 seconds minimum just for cmd/bd.

## 2. Each Test Creates Full Database + Temp Directories
Every test does heavy setup:
- Creates temp directory (`t.TempDir()` or `os.MkdirTemp`)
- Initializes SQLite database
- Sets up git repo in many cases
- Creates full storage layer

Example from the tests:
```go
func setupCLITestDB(t *testing.T) string {
    tmpDir := createTempDirWithCleanup(t)
    runBDInProcess(t, tmpDir, "init", "--prefix", "test", "--quiet")
    return tmpDir
}
```

This happens 279 times!

## 3. Tests Are Not Properly Categorized
We have three types of tests mixed together:
- **Unit tests** - should be fast, test single functions
- **Integration tests** - test full workflows, need DB/git
- **End-to-end tests** - test entire CLI commands

They're all lumped together in cmd/bd, all running every time.

# What We've Already Fixed

Added `integration` build tags to 16 obviously-slow test files:
- import_profile_test.go (performance benchmarking tests)
- export_mtime_test.go (tests with time.Sleep calls)
- cli_fast_test.go (full CLI integration tests)
- delete_test.go, import_uncommitted_test.go, sync_local_only_test.go (git integration)
- And 10 more in internal/ packages

These are now excluded from the default `go test ./...` run.

# Proposed Solutions

## Option 1: Shared Test Fixtures (Quick Win)
Create a shared test database that multiple tests can use:
```go
var testDB *sqlite.SQLiteStorage
var testDBOnce sync.Once

func getSharedTestDB(t *testing.T) storage.Storage {
    testDBOnce.Do(func() {
        // Create one DB for all tests
    })
    return testDB
}
```

**Pros**: Easy to implement, immediate speedup
**Cons**: Tests become less isolated, harder to debug failures

## Option 2: Table-Driven Tests (Medium Win)
Collapse similar tests into table-driven tests:
```go
func TestCreate(t *testing.T) {
    tests := []struct{
        name string
        args []string
        want string
    }{
        {"basic issue", []string{"create", "Test"}, "created"},
        {"with description", []string{"create", "Test", "-d", "desc"}, "created"},
        // ... 50 more cases
    }

    db := setupOnce(t) // Setup once, not 50 times
    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            // test using shared db
        })
    }
}
```

**Pros**: Dramatically reduces setup overhead, tests run in parallel
**Cons**: Requires refactoring, tests share more state

## Option 3: Split cmd/bd Tests Into Packages (Big Win)
Move tests into focused packages:
- `cmd/bd/internal/clitests` - CLI integration tests (mark with integration tag)
- `cmd/bd/internal/unittests` - Fast unit tests
- Keep only essential tests in cmd/bd

**Pros**: Clean separation, easy to run just fast tests
**Cons**: Requires significant refactoring

## Option 4: Parallel Execution (Quick Win)
Add `t.Parallel()` to independent tests:
```go
func TestSomething(t *testing.T) {
    t.Parallel() // Run this test concurrently with others
    // ...
}
```

**Pros**: Easy to add, can cut time in half on multi-core machines
**Cons**: Doesn't reduce actual test work, just parallelizes it

## Option 5: In-Memory Databases (Medium Win)
Use `:memory:` SQLite databases instead of file-based:
```go
store, err := sqlite.New(ctx, ":memory:")
```

**Pros**: Faster than disk I/O, easier cleanup
**Cons**: Some tests need actual file-based DBs (export/import tests)

# Recommended Approach

**Short-term (this week)**:
1. Add `t.Parallel()` to all independent tests in cmd/bd
2. Use `:memory:` databases where possible
3. Create table-driven tests for similar test cases

**Medium-term (next sprint)**:
4. Split cmd/bd tests into focused packages
5. Mark more integration tests appropriately

**Long-term (backlog)**:
6. Consider shared test fixtures with proper isolation

# Current Status

We've tagged 16 files with `integration` build tag, but the remaining 279 tests in cmd/bd still take 8+ minutes. This issue tracks fixing the cmd/bd test performance specifically.

# Target

Get `go test ./...` (without `-short` or `-tags=integration`) down to **under 30 seconds**.

# THE REAL ROOT CAUSE (Updated Analysis)

After examining the actual test code, the problem is clear:

## Every Test Creates Its Own Database From Scratch

Look at `create_test.go`:
```go
func TestCreate_BasicIssue(t *testing.T) {
    tmpDir := t.TempDir()                          // ← Creates temp dir
    testDB := filepath.Join(tmpDir, ".beads", "beads.db")
    s := newTestStore(t, testDB)                   // ← Opens NEW SQLite connection
                                                    // ← Runs migrations
                                                    // ← Sets config
    // ... actual test (3 lines)
}

func TestCreate_WithDescription(t *testing.T) {
    tmpDir := t.TempDir()                          // ← Creates ANOTHER temp dir
    testDB := filepath.Join(tmpDir, ".beads", "beads.db")
    s := newTestStore(t, testDB)                   // ← Opens ANOTHER SQLite connection
    // ... actual test (3 lines)
}
```

**This happens 279 times!**

## These Tests Don't Need Isolation!

Most tests are just checking:
- "Can I create an issue with a title?"
- "Can I create an issue with a description?"
- "Can I add labels?"

They don't conflict with each other. They could all share ONE database!

## The Fix: Test Suites with Shared Setup

Instead of:
```go
func TestCreate_BasicIssue(t *testing.T) {
    s := newTestStore(t, t.TempDir()+"/db")  // ← Expensive!
    // test
}

func TestCreate_WithDesc(t *testing.T) {
    s := newTestStore(t, t.TempDir()+"/db")  // ← Expensive!
    // test
}
```

Do this:
```go
func TestCreate(t *testing.T) {
    // ONE setup for all subtests
    s := newTestStore(t, t.TempDir()+"/db")

    t.Run("basic_issue", func(t *testing.T) {
        t.Parallel()  // Can run concurrently - tests don't conflict
        // test using shared `s`
    })

    t.Run("with_description", func(t *testing.T) {
        t.Parallel()
        // test using shared `s`
    })

    // ... 50 more subtests, all using same DB
}
```

**Result**: 50 tests → 1 database setup instead of 50!

## Why This Works

SQLite is fine with concurrent reads and isolated transactions. These tests:
- ✅ Create different issues (no ID conflicts)
- ✅ Just read back what they created
- ✅ Don't depend on database state from other tests

They SHOULD share a database!

## Real Numbers

Current:
- 279 tests × (create dir + init SQLite + migrations) = **8 minutes**

After fix:
- 10 test suites × (create dir + init SQLite + migrations) = **30 seconds**
- 279 subtests running in parallel using those 10 DBs = **5 seconds**

**Total: ~35 seconds instead of 8 minutes!**

## Implementation Plan

1. **Group related tests** into suites (Create, List, Update, Delete, etc.)
2. **One setup per suite** instead of per test
3. **Use t.Run() for subtests** with t.Parallel()
4. **Keep tests that actually need isolation** separate (export/import tests, git operations)

This is way better than shuffling tests into folders!

## Progress Update (2025-11-21)

✅ **Completed**:
- Audited all 280 tests, created TEST_SUITE_AUDIT.md ([deleted:bd-c49])
- Refactored create_test.go to shared DB pattern ([deleted:bd-y6d])
- Proven the pattern works: 11 tests now run in 0.04s with 1 DB instead of 11

❌ **Current Reality**:
- Overall test suite: Still 8+ minutes (no meaningful change)
- Only 1 of 76 test files refactored
- Saved ~10 DB initializations out of 280

## Acceptance Criteria (REALISTIC)

This task is NOT complete until:
- [ ] All P1 files refactored (create ✅, dep, stale, comments, list, ready)
- [ ] Test suite runs in < 2 minutes
- [ ] Measured and verified actual speedup

## Next Steps

1. Refactor remaining 5 P1 files: dep_test.go, stale_test.go, comments_test.go, list_test.go, ready_test.go
2. Measure actual time improvement after each file
3. Continue with P2 files if needed to hit <2min target


Add ON DELETE CASCADE to child_counters schema

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

Clarify exclusive lock protocol compatibility with multi-repo

The contributor-workflow-analysis.md proposes per-repo file locking (Decision #7) using flock on JSONL files. However, VC (a downstream library consumer) uses an exclusive lock protocol (vc-195, requires Beads v0.17.3+) that allows bd daemon and VC executor to coexist.

Need to clarify:
- Does the proposed per-repo file locking work with VC's existing exclusive lock protocol?
- Do library consumers like VC need to adapt their locking logic?
- Can multiple repos be locked atomically for cross-repo operations?

Context: contributor-workflow-analysis.md lines 662-681


Frontend task


bd-hv01: Three full JSONL reads on every sync (performance)

Problem: computeAcceptedDeletions reads three JSONL files completely into memory (base, left, merged). For 1000 issues at 1KB each, this is 3MB read and 3000 JSON parse operations.

Impact: Acceptable now (~20-35ms overhead) but will be slow for large repos (10k+ issues).

Possible optimizations: single-pass streaming, memory-mapped files, binary format, incremental snapshots.

Files: cmd/bd/deletion_tracking.go:101-208


Implement "bd daemons logs" subcommand

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


bd hooks install fails in git worktrees

When bd is used in a git worktree, bd hooks install fails with 'mkdir .git: not a directory' because .git is a file (gitdir pointer) not a directory. Beads should detect and follow the .git gitdir pointer to install hooks in the correct location. This blocks normal worktree workflows.

## Symptoms of this bug:
- Git hooks don't install automatically
- Auto-sync doesn't run (5-second debounce)
- Hash mismatch warnings in bd output
- Daemon fails to start with 'auto_start_failed'

## Workaround:
Use `git rev-parse --git-dir` to find the actual hooks directory and copy hooks manually:
```bash
mkdir -p $(git rev-parse --git-dir)/hooks
cp -r .beads-hooks/* $(git rev-parse --git-dir)/hooks/
```


Add Agent Mail to QUICKSTART.md

Mention Agent Mail as optional advanced feature in quickstart guide.

File: docs/QUICKSTART.md


Support separate branch for beads commits

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

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

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

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


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


Add unit tests for config modes

Test all four orphan_handling modes: strict (fails), resurrect (creates tombstone), skip (logs warning), allow (imports orphan). Verify error messages and logging output for each mode.


Production Readiness (Optional)

Enable multi-machine deployments with containerization and monitoring.


Deletions pruning doesn't include results in JSON output

## Problem

When `bd compact --json` runs with deletions pruning, the prune results are silently discarded:

```go
// Only report if there were deletions to prune
if result.PrunedCount > 0 {
    if jsonOutput {
        // JSON output will be included in the main response
        return  // <-- BUG: results are NOT included anywhere
    }
    ...
}
```

## Location
`cmd/bd/compact.go:925-929`

## Impact
- JSON consumers don't know deletions were pruned
- No way to audit pruning via automation

## Fix
Return prune results and include in JSON output structure:

```json
{
  "success": true,
  "compacted": {...},
  "deletions_pruned": {
    "count": 5,
    "retention_days": 7
  }
}
```


Cache getMultiRepoJSONLPaths() result during sync to avoid redundant calls

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

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

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

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

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

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

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

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

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

        // ... later ...

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

        // ... later ...

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

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

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


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.


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.


Handle unchecked errors (errcheck - 683 issues)

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

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


Extract database search logic into helper function

The logic for finding a database in a beads directory is duplicated:
- FindDatabasePath() BEADS_DIR section (beads.go:141-169)
- findDatabaseInTree() (beads.go:248-280)

Both implement the same search order:
1. Check config.json first (single source of truth)
2. Fall back to canonical beads.db
3. Search for *.db files, filtering backups and vc.db

Refactoring suggestion:
Extract to a helper function like:
  func findDatabaseInBeadsDir(beadsDir string) string

Benefits:
- Single source of truth for database search logic
- Easier to maintain and update search order
- Reduces code duplication

Related to [deleted:bd-e16b] implementation.


deletions.jsonl recreated locally after tombstone migration

After running bd migrate-tombstones and removing deletions.jsonl from git, the file gets recreated locally on subsequent bd commands.

**Steps to reproduce:**
1. Run bd migrate-tombstones (converts to inline tombstones)
2. Remove deletions.jsonl from git and filesystem
3. Run bd sync or bd stats
4. deletions.jsonl reappears

**Expected behavior:**
After migration, deletions.jsonl should not be recreated. All tombstone data should come from inline tombstones in issues.jsonl.

**Workaround:** Add deletions.jsonl to .gitignore to prevent re-tracking. File still gets created but won't pollute the repo.


Test issue 2


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.


Consolidate export/import/commit/push into sync.go

Create internal/daemonrunner/sync.go with Syncer type. Add ExportOnce, ImportOnce, CommitAndMaybePush methods. Replace createExportFunc/createAutoImportFunc with thin closures calling Syncer.


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


Add test coverage for internal/config package


Add t.Parallel() to slow hash multiclone tests

Add t.Parallel() to TestHashIDs_MultiCloneConverge and TestHashIDs_IdenticalContentDedup so they run concurrently.

Expected savings: ~10 seconds (from 20s to ~11s)

Implementation:
- Add t.Parallel() call at start of each test function
- Verify tests don't share resources that would cause conflicts
- Run tests to confirm they work in parallel

File: beads_hash_multiclone_test.go:34, :101


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

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

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

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

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

Where suffix is first 4 chars of clone UUID.

## Implementation

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

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

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

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

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

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

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

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

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

Add validation for duplicate external_ref in batch imports

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

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

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

Modify CreateIssue to support parent resurrection

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


Review PR #513: fix hooks install docs

Review and merge PR #513 from aspiers. This PR fixes incorrect docs for how to install git hooks - updates README to use bd hooks install instead of removed install.sh. Simple 1-line change. URL: https://github.com/anthropics/beads/pull/513


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.


Add tests for Integration Layer Implementation

While implementing bd-wfmw, noticed missing tests

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

Feature P1


GH#532: bd sync circular error (suggests running bd sync)

bd sync error message recommends running bd sync to fix the bd sync error. Fix error handling to provide useful guidance. See GitHub issue #532.


getLocalSyncBranch silently ignores YAML parse errors

In autoimport.go:170-172, YAML parsing errors are silently ignored. If a user has malformed YAML in config.yaml, sync-branch will just silently be empty with no feedback.

Recommendation: Add debug logging since this function is only called during auto-import, and debugging silent failures is painful.

Add: debug.Logf("Warning: failed to parse config.yaml: %v", err)


Update AGENTS.md and README.md with "bd daemons" documentation

Document the new "bd daemons" command and all subcommands in AGENTS.md and README.md. Include examples and troubleshooting guidance.


Import validation falsely reports data loss on collision resolution

## Problem

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

## Example

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

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

## Impact

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

## Solution

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

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


User Diagnostics (bd doctor --perf)

Extend cmd/bd/doctor.go to add --perf flag for user performance diagnostics.

Functionality:
- Add --perf flag to existing bd doctor command
- Collect system info (OS, arch, Go version, SQLite version)
- Collect database stats (size, issue counts, dependency counts)
- Time key operations on user's actual database:
  * bd ready
  * bd list --status=open
  * bd show <random-issue>
  * bd create (with rollback)
  * Search with filters
- Generate CPU profile automatically (timestamped filename)
- Output simple report with platform info, timings, profile location

Output example:
  Beads Performance Diagnostics
  Platform: darwin/arm64
  Database: 8,234 issues (4,123 open)

  Operation Performance:
    bd ready                  42ms
    bd list --status=open     15ms

  Profile saved: beads-perf-2025-11-13.prof
  View: go tool pprof -http=:8080 beads-perf-2025-11-13.prof

Implementation:
- Extend cmd/bd/doctor.go (~100 lines)
- Use runtime/pprof for CPU profiling
- Use time.Now()/time.Since() for timing
- Rollback test operations (don't modify user's database)

- Implement CheckWorktreeHealth(path)
- Configure sparse checkout (only .beads/)
- Implement SyncJSONLToWorktree()
- Handle worktree errors gracefully
- Auto-cleanup on config change

Estimated effort: 3-4 days


Database pollution in ~/src/dave/vc: 895 issues vs canonical 310

~/src/dave/vc/.beads/beads.db has 895 total issues (675 open, 149 closed), but canonical ~/src/vc/.beads/vc.db has only 310 issues (230 open). This is 585 extra issues - likely pollution from other repositories.

Need to:
1. Identify which issues are polluted (use detect-pollution)
2. Compare issue IDs between dave/vc and canonical vc databases
3. Determine pollution source (beads repo? other repos?)
4. Clean up polluted database
5. Root cause: why did pollution occur?

Investigation findings so far:
- Polluted DB (~/src/dave/vc/.beads/beads.db): 241 issues (180 open, 43 closed)
- Canonical DB (~/src/vc/.beads/vc.db): 310 issues (230 open, 62 closed)
- Contradiction: Polluted has FEWER issues, not more (241 < 310, diff of 69)
- Only 1 unique ID in polluted: vc-55fi
- All source_repo fields are set to "." in both databases
- Issue description claims 895 issues in polluted vs 310 canonical - numbers don't match current state
- Possible: Pollution was already partially cleaned, or issue description refers to different database?


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-cbed9619.3, bd-dcd6f14b 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-hv01: Missing cleanup of .merged temp file on failure

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

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

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


Reduce global state in cmd/bd/main.go (25+ variables)

Code health review found main.go has 25+ global variables (lines 57-112):

- dbPath, actor, store, jsonOutput, daemonClient, noDaemon
- rootCtx, rootCancel, autoFlushEnabled
- isDirty (marked 'USED BY LEGACY CODE')
- needsFullExport (marked 'USED BY LEGACY CODE')
- flushTimer (marked 'DEPRECATED')
- flushMutex, storeMutex, storeActive
- flushFailureCount, lastFlushError, flushManager
- skipFinalFlush, autoImportEnabled
- versionUpgradeDetected, previousVersion, upgradeAcknowledged

Impact:
- Hard to test individual commands
- Race conditions possible
- State leakage between commands

Fix: Move toward dependency injection. Remove deprecated variables. Consider cmd/bd/internal package.


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.


Fix hasJSONLChanged to support per-repo metadata keys

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

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

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

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

Update all callers to pass correct keySuffix.


Refactor sqlite.go into focused modules

Split sqlite.go (2,298 lines) into focused modules: migrations.go, ids.go, issues.go, events.go, dirty.go, db.go. This will improve maintainability and reduce cognitive load.


Add bd deleted command for audit trail

Parent: bd-imj

Add command to view deletion history.

Usage:
  bd deleted              # Show recent deletions (last 7 days)
  bd deleted --since=30d  # Show deletions in last 30 days
  bd deleted --all        # Show all tracked deletions
  bd deleted bd-xxx       # Show deletion details for specific issue

Output format:
  bd-xxx  2025-11-25 10:00  stevey  duplicate of bd-yyy
  bd-yyy  2025-11-25 10:05  claude  cleanup

Acceptance criteria:
- List deletions with timestamp, actor, reason
- Filter by time range
- Lookup specific issue ID
- JSON output option for scripting


Support Ubuntu 20.04 LTS (glibc compatibility issue)

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

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

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

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

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

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

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


Remove duplicate countIssuesInJSONLFile function

init.go and doctor.go both defined countIssuesInJSONLFile. Removed the init.go version which is now unused. The doctor.go version (which calls countJSONLIssues) is the canonical implementation.


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


Consider backwards compatibility for ready() and list() return type change

PR #481 changed the return types of `ready()` and `list()` from `list[Issue]` to `list[IssueMinimal] | CompactedResult`. This is a breaking change for MCP clients.

## Impact Assessment
Breaking change affects:
- Any MCP client expecting `list[Issue]` from ready()
- Any MCP client expecting `list[Issue]` from list()
- Client code that accesses full Issue fields (description, design, acceptance_criteria, timestamps, dependencies, dependents)

## Current Behavior
- ready() returns `list[IssueMinimal] | CompactedResult`
- list() returns `list[IssueMinimal] | CompactedResult`
- show() still returns full `Issue` (good)

## Considerations
**Pros of current approach:**
- Forces clients to use show() for full details (good for context efficiency)
- Simple mental model (always use show for full data)
- Documentation warns about this

**Cons:**
- Clients expecting list[Issue] will break
- No graceful degradation option
- No migration period

## Potential Solutions
1. Add optional parameter `full_details=false` to ready/list (would increase payload)
2. Create separate tools: ready_minimal/list_minimal + ready_full/list_full
3. Accept breaking change and document upgrade path (current approach)
4. Version the MCP server and document migration guide

## Recommendation
Current approach (solution 3) is reasonable if:
- Changelog clearly documents the breaking change
- Migration guide provided to clients
- Error handling is graceful for clients expecting specific fields


bd-hv01: No snapshot versioning or timestamps causes stale data usage

Problem: If sync is interrupted (crash, kill -9, power loss), stale snapshots persist indefinitely. Next sync uses stale data leading to incorrect deletions.

Fix: Add metadata to snapshots with timestamp, version, and commit SHA. Validate snapshots are recent (< 1 hour old), from compatible version, and from expected git commit.

Files: cmd/bd/deletion_tracking.go (all snapshot functions)


Add import metrics for external_ref matching statistics

Add observability for external_ref matching behavior during imports to help debug and optimize import operations.

Metrics to track:
- Number of issues matched by external_ref
- Number of issues matched by ID
- Number of issues matched by content hash
- Number of external_ref updates vs creates
- Average import time with vs without external_ref

Output format:
- Add to ImportResult struct
- Include in import command output
- Consider structured logging

Use cases:
- Debugging slow imports
- Understanding match distribution
- Optimizing import performance

GH#540: Add silent quick-capture mode (bd q)

Add bd q alias for quick capture that outputs only issue ID. Useful for piping/scripting. See GitHub issue #540.


Add commit and branch to bd version output

The 'bd version' command reports commit and branch correctly when built with 'go build' (thanks to Go 1.25+ automatic VCS info embedding), but NOT when installed with 'go install' or 'make install'. Need to either: 1) Update Makefile to use 'go build' instead of 'go install', or 2) Add explicit ldflags to both Makefile and .goreleaser.yml to ensure commit/branch are always set regardless of build method.


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


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


Document error handling strategy for metadata update failures

Multiple places silently ignore metadata update failures (sync.go:614-617, import.go:320-322) with non-fatal warnings. This is intentional (degrades gracefully to mtime-based approach) but not well documented.

Add comments explaining:
- Why these failures are non-fatal
- How system degrades gracefully
- What the fallback behavior is (mtime-based detection)

Standardize daemon detection: use tryDaemonLock probe before RPC

Before attempting RPC connection, call tryDaemonLock() to check if lock is held:
- If lock NOT held: skip RPC attempt (no daemon running)
- If lock IS held: proceed with RPC + short timeout

This is extremely cheap and eliminates unnecessary connection attempts.

Apply across all client entry points that probe for daemon.

GH#486: Claude forgets beads workflow mid-session

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


Mail Commands: bd mail send/inbox/read/ack

Implement core mail commands in cmd/bd/mail.go

Commands:
- bd mail send <recipient> -s 'Subject' -m 'Body' [--urgent]
  - Creates issue with type=message, sender=identity, assignee=recipient
  - --urgent sets priority=0

- bd mail inbox [--from <sender>] [--priority <n>]
  - Lists open messages where assignee=my identity
  - Sorted by priority, then date

- bd mail read <id>
  - Shows full message content (subject, body, sender, timestamp)
  - Does NOT close (separate from ack)

- bd mail ack <id>
  - Marks message as read by closing it
  - Can ack multiple: bd mail ack <id1> <id2> ...

Requires: Identity configuration (bd-kwro.7)


Investigation & Proof of Concept

Validate that MCP Agent Mail works as expected and delivers promised benefits before committing to full integration.

POC completed successfully:
✅ bd-muls: Server installed and tested
✅ bd-27xm: MCP tool execution issues resolved
✅ [deleted:bd-6hji]: File reservation collision prevention validated
✅ bd-htfk: Latency benchmarking shows 20-50x improvement
✅ bd-pmuu: ADR 002 created documenting integration decision

Results validate Agent Mail benefits:
- Collision prevention works (exclusive file reservations)
- Latency: <100ms (vs 2000-5000ms git sync)
- Lightweight deployment (<50MB memory)
- Optional/non-intrusive integration approach validated

Next: bd-wfmw (Integration Layer Implementation)

Fix TestImportBugIntegration deadlock in importer_test.go

Code health review found internal/importer/importer_test.go has TestImportBugIntegration skipped with:

TODO: Test hangs due to database deadlock - needs investigation

This indicates a potential unresolved concurrency issue in the importer. The test has been skipped for an unknown duration.

Fix: Investigate the deadlock, fix the underlying issue, and re-enable the test.


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.


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)


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.


Document which files to commit after bd init --branch

GH #312 reported confusion about which files should be committed after running 'bd init --branch beads-metadata'. Updated PROTECTED_BRANCHES.md to clearly document:

1. Files that should be committed to protected branch (main):
   - .beads/.gitignore
   - .gitattributes

2. Files that are automatically gitignored
3. Files that live in the sync branch (beads-metadata)

Changes:
- Added step-by-step instructions in Quick Start section
- Added 'What lives in each branch' section to How It Works
- Clarified the directory structure diagram

Fixes: https://github.com/steveyegge/beads/issues/312


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.


Refactor AGENTS.md to use external references

Suggestion to use external references (e.g., "ALWAYS REFER TO ./beads/prompt.md") instead of including all instructions directly within AGENTS.md.
Reasons:
1. Agents can follow external references.
2. Prevents context pollution/stuffing in AGENTS.md as more tools append instructions.


Reduce sync rounds in multiclone tests

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

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

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

File: beads_hash_multiclone_test.go:70, :132


bd ready includes blocked issues (GH#544)

Issues with 'blocks' dependencies still appear in bd ready. The ready query should exclude issues that have unresolved blockers.

Fix in: cmd/bd/ready.go or internal query logic.


Create npm package structure for bd-wasm

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


Add 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

Related: bd-1022


Improve test coverage for internal/daemon (27.3% → 60%)

The daemon package has only 27.3% test coverage. The daemon is critical for background operations and reliability.

Key areas needing tests:
- Daemon autostart logic
- Socket handling
- PID file management
- Health checks

Current coverage: 27.3%
Target coverage: 60%


GH#517: Claude sets priority wrong on new install

Claude uses 'medium/high/low' for priority instead of P0-P4. Update bd prime/onboard output to be clearer about priority syntax. See GitHub issue #517.


Improve sync branch divergence recovery UX

When the sync branch diverges significantly from remote (e.g., 89 local vs 36 remote commits), bd sync fails with a confusing rebase conflict error.

**Current behavior:**
```
Error committing to sync branch: failed to push from worktree: push failed and recovery rebase also failed
error: could not apply 8712f35... bd sync: 2025-12-13 07:30:04
CONFLICT (content): Merge conflict in .beads/issues.jsonl
```

User is left in a broken state with no clear recovery path.

**Expected behavior:**
1. Detect significant divergence before attempting sync
2. Offer options: 'Sync branch diverged. Choose: (1) Reset to remote (2) Force push local (3) Manual merge'
3. Provide clear recovery commands if automatic recovery fails

**Context:** This happened after multiple clones synced different states. The workaround was manually resetting the sync branch worktree to remote.


Fix TestMigrateHashIDs test failure

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


Vendor beads-merge Go code into internal/merge/

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

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

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


Add unit tests for parent resurrection

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


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


bd message: Add HTTP client timeout to prevent hangs

HTTP client in `sendAgentMailRequest` uses default http.Post with no timeout.

**Location:** cmd/bd/message.go:181

**Problem:**
- Can hang indefinitely if server is unresponsive
- No way to cancel stuck requests
- Poor UX in flaky networks

**Fix:**
```go
client := &http.Client{Timeout: 30 * time.Second}
resp, err := client.Post(url, "application/json", bytes.NewReader(reqBody))
```

**Impact:** Production reliability and security issue


Wrap git operations in GitClient interface

Create internal/daemonrunner/git.go with GitClient interface (HasUpstream, HasChanges, Commit, Push, Pull). Default implementation using os/exec. Use in Syncer and Run loop for testability.


Improve test coverage for internal/export (37.1% → 60%)

The export package has only 37.1% test coverage. Export functionality needs good coverage to ensure data integrity.

Current coverage: 37.1%
Target coverage: 60%


False positive detection by Kaspersky Antivirus (Trojan)

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


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

Design contributor namespace isolation for beads pollution prevention

## Problem

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

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

## Possible Solutions to Explore

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

## Design Considerations

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

## Expansion Needed

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


Remove or fix ClearDirtyIssues() - race condition risk (bd-52)

Code health review found internal/storage/sqlite/dirty.go still exposes old ClearDirtyIssues() method (lines 103-108) which clears ALL dirty issues without checking what was actually exported.

Data loss risk: If export fails after some issues written to JSONL but before ClearDirtyIssues called, changes to remaining dirty issues will be lost.

The safer ClearDirtyIssuesByID() (lines 113-132) exists and clears only exported issues.

Fix: Either remove old method or mark it deprecated and ensure no code paths use it.


Test message

This is a test message body


Fix N-way collision convergence

Epic to fix the N-way collision convergence problem documented in n-way-collision-convergence.md.

## Problem Summary
The current collision resolution implementation works correctly for 2-way collisions but does not converge for 3-way (and by extension N-way) collisions. TestThreeCloneCollision demonstrates this with reproducible failures.

## Root Causes Identified
1. Pairwise resolution doesn't scale - each clone makes local decisions without global context
2. DetectCollisions modifies state during detection (line 83-86 in collision.go)
3. No remapping history - can't track transitive remap chains (test-1 → test-2 → test-3)
4. Import-time resolution is too late - happens after git merge

## Solution Architecture
Replace pairwise resolution with deterministic global N-way resolution using:
- Content-addressable identity (content hashing)
- Global collision resolution (sort all versions by hash)
- Read-only detection phase (separate from modification)
- Idempotent imports (content-first matching)

## Success Criteria
- TestThreeCloneCollision passes without skipping
- All clones converge to identical content after final pull
- No data loss (all issues present in all clones)
- Works for N workers (test with 5+ clones)
- Idempotent imports (importing same JSONL multiple times is safe)

## Implementation Phases
See child issues for detailed breakdown of each phase.

Fix variable shadowing in GetNextChildID resurrection code

## Problem
Minor variable shadowing in hash_ids.go:

```go
// Line 33: err declared here
err := s.db.QueryRowContext(ctx, `SELECT COUNT(*) FROM issues WHERE id = ?`, parentID).Scan(&count)

// Line 38: err reused/shadowed here
resurrected, err := s.TryResurrectParent(ctx, parentID)
```

While Go allows this, it can be confusing and some linters flag it.

## Solution
Use different variable name:

```go
resurrected, resurrectErr := s.TryResurrectParent(ctx, parentID)
if resurrectErr != nil {
    return "", fmt.Errorf("failed to resurrect parent %s: %w", parentID, resurrectErr)
}
```

## Files
- internal/storage/sqlite/hash_ids.go:38

## Priority
Low - code works correctly, just a style improvement


Create deployment scripts for GCP

Automated provisioning scripts for GCP Compute Engine deployment.

Acceptance Criteria:
- Terraform/gcloud scripts
- Static IP allocation
- Firewall rules
- NGINX reverse proxy config
- TLS setup (Let's Encrypt)
- Systemd service file

File: deployment/agent-mail/gcp/


Add comprehensive filters to bd export

Enhance bd export with filtering options for selective exports.

**Currently only has:**
- --status

**Add filters:**
- --label, --label-any
- --assignee
- --type
- --priority, --priority-min, --priority-max
- --created-after, --created-before
- --updated-after, --updated-before

**Use case:**
- Export only open issues: bd export --status open
- Export high-priority bugs: bd export --type bug --priority-max 1
- Export recent issues: bd export --created-after 2025-01-01

**Files to modify:**
- cmd/bd/export.go
- Reuse filter logic from list.go


Git merge driver uses invalid placeholders (%L, %R instead of %A, %B)

## Problem

The beads git merge driver is configured with invalid Git placeholders:

```
git config merge.beads.driver "bd merge %A %O %L %R"
```

Git doesn't recognize `%L` or `%R` as valid merge driver placeholders. The valid placeholders are:
- `%O` = base (common ancestor)
- `%A` = current version (ours)
- `%B` = other version (theirs)

## Impact

- Affects ALL users when they have `.beads/beads.jsonl` merge conflicts
- Automatic JSONL merge fails with error: "error reading left file: failed to open file: open 7: no such file or directory"
- Users must manually resolve conflicts instead of getting automatic merge

## Root Cause

The `bd init` command (or wherever the merge driver is configured) is using non-standard placeholders. When Git encounters `%L` and `%R`, it either passes them literally or interprets them incorrectly.

## Fix

Update the merge driver configuration to:
```
git config merge.beads.driver "bd merge %A %O %A %B"
```

Where:
- 1st `%A` = output file (current file, will be overwritten)
- `%O` = base (common ancestor)
- 2nd `%A` = left/current version
- `%B` = right/other version

## Action Items

1. Fix `bd init` (or equivalent setup command) to use correct placeholders
2. Add migration/warning for existing users with misconfigured merge driver
3. Update documentation with correct merge driver setup
4. Consider adding validation when `bd init` is run


Improve CheckStaleness error handling

## Problem

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

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

## Edge Cases That Return False

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

## Fix

Return errors for abnormal conditions:

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

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

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

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

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

cmd/bd tests fail without -short flag (parallel test deadlock)


Enforce daemon singleton per workspace with file locking

Agent in ~/src/wyvern discovered 4 simultaneous daemon processes running, causing infinite directory recursion (.beads/.beads/.beads/...). Each daemon used relative paths and created nested .beads/ directories.

Root cause: No singleton enforcement. Multiple `bd daemon` processes can start in same workspace.

Expected: One daemon per workspace (each workspace = separate .beads/ dir with bd.sock)
Actual: Multiple daemons can run simultaneously in same workspace

Note: Separate git clones = separate workspaces = separate daemons (correct). Git worktrees share .beads/ and have known limitations (documented, use --no-daemon).

## Fix Summary

Successfully prevented the nested .beads/.beads/ recursion bug by implementing two safeguards:

1. **Path Canonicalization in FindDatabasePath()** (beads.go):
   - Added filepath.Abs() + filepath.EvalSymlinks() to normalize all database paths
   - Prevents relative path edge cases that create nested directories
   - Ensures all daemons see the same canonical path

2. **Nested Directory Detection** (daemon_lifecycle.go):
   - Added explicit check for ".beads/.beads" pattern in setupDaemonLock()
   - Fails fast with clear error message if nested structure detected
   - Provides user hints about proper usage

## Root Cause

The daemon lock (added Oct 22, 2025) correctly prevents simultaneous daemons in the SAME workspace. However, when BEADS_DB used a relative path (e.g., ".beads/beads.db") from inside the .beads directory, FindDatabasePath() would resolve it to a nested path creating a separate workspace:
- First daemon: /workspace/.beads/beads.db
- Second daemon from .beads/: /workspace/.beads/.beads/beads.db ← Different lock file!

## Testing

All acceptance criteria passed:
✅ 1. Second daemon start fails with "daemon already running" error
✅ 2. Killing daemon releases lock, new daemon can start
✅ 3. No infinite .beads/ recursion possible (tested nested BEADS_DB path)
✅ 4. Works with auto-start mechanism

The fix addresses the edge case while maintaining the existing lock mechanism's correctness.


bd import fails on duplicate external_ref with no resolution options

When JSONL contains duplicate external_ref values (e.g., two issues both have external_ref='BS-170'), bd import fails entirely with no resolution options.

User must manually edit JSONL to remove duplicates, which is error-prone.

Example error:
```
batch import contains duplicate external_ref values:
external_ref 'BS-170' appears in issues: [opal-39 opal-43]
```

Should handle this similar to duplicate issue detection - offer to merge, pick one, or clear duplicates.

Add .beads-backup-* pattern to gitignore template

Update the gitignore template in doctor package to include backup directories.

## Change
Add `.beads-backup-*/` to the GitignoreTemplate in `cmd/bd/doctor/gitignore.go`

## Why
Backup directories created by `bd reset --backup` should not be committed to git.
They are local-only recovery tools.

## File
`cmd/bd/doctor/gitignore.go` - look for GitignoreTemplate constant

### README.md
- Brief mention in .beads directory structure section
- Link to detailed docs if needed

### docs/deletions.md (new file)
- Full technical documentation
- Format specification
- Pruning policy
- Git history fallback
- Troubleshooting

## Acceptance Criteria
- AGENTS.md updated with deletion workflow
- README.md mentions deletions.jsonl purpose
- New docs/deletions.md with complete reference


Add unit tests for import ordering

Test topological sort: import [child, parent] should succeed, import [parent.1.2, parent, parent.1] should sort correctly. Verify depth-based batching works. Test max depth limits.


Implement auto-merge functionality in duplicates command

The duplicates.go file has a TODO at line 95 to implement the performMerge function for automatic duplicate merging. Currently it just prints a warning message. This would automate the merge process instead of just suggesting commands.


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

## Feature Request

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

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

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

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


Improve test coverage for cmd/bd CLI (26.2% → 50%)

The main CLI package (cmd/bd) has only 26.2% test coverage. CLI commands should have at least 50% coverage to ensure reliability.

Key areas with low/no coverage:
- daemon_autostart.go (multiple 0% functions)
- compact.go (several 0% functions)
- Various command handlers

Current coverage: 26.2%
Target coverage: 50%

Extract Daemon struct and config into internal/daemonrunner

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

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

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


Improve timestamp comparison readability in import

The timestamp comparison logic uses double-negative which can be confusing:

Current code:
if !incoming.UpdatedAt.After(existing.UpdatedAt) {
    // skip update
}

More readable:
if incoming.UpdatedAt.After(existing.UpdatedAt) {
    // perform update
} else {
    // skip (local is newer)
}

This is a minor refactor for code clarity.

Add schema compatibility probe to prevent silent migration failures

Issue #262 revealed a serious bug: migrations may fail silently, causing UNIQUE constraint errors later.

Root cause:
- sqlite.New() runs migrations once on open
- checkVersionMismatch() prints 'database will be upgraded automatically' but only updates metadata
- If migrations fail or daemon runs older version, queries expecting new columns fail with 'no such column'
- Import logic misinterprets this as 'not found' and tries INSERT on existing ID
- Result: UNIQUE constraint failed: issues.id

Fix strategy (minimal):
1. Add schema probe in sqlite.New() after RunMigrations
   - SELECT all expected columns from all tables with LIMIT 0
   - If fails, retry RunMigrations and probe again
   - If still fails, return fatal error with clear message
2. Fix checkVersionMismatch to not claim 'will upgrade' unless probe passes
3. Only update bd_version after successful migration probe
4. Add schema verification before import operations
5. Map 'no such column' errors to clear actionable message

Fix FOREIGN KEY constraint failures in AddComment and ApplyCompaction

The 'CloseIssue', 'UpdateIssueID', and 'RemoveLabel' methods were fixed in PR #348 to prevent foreign key constraint failures when operating on non-existent issues.

However, the Oracle identified two other methods that follow the same problematic pattern:
1. `AddComment` (in `internal/storage/sqlite/events.go`)
2. `ApplyCompaction` (in `internal/storage/sqlite/compact.go`)

These methods attempt to insert an event record after updating the issue, without verifying that the issue update actually affected any rows. This leads to a foreign key constraint failure if the issue does not exist.

We need to:
1. Create reproduction tests for these failure cases
2. Apply the same fix pattern: check `RowsAffected()` after the update, and return a proper "issue not found" error if it is 0, before attempting to insert the event.
3. Standardize the error message format to "issue %s not found" or "issue not found: %s" for consistency.


GH#518: Document bd setup command

bd setup (e.g. bd setup cursor) is undocumented. Users only find it by grepping source. Need proper docs. See: https://github.com/steveyegge/beads/issues/518


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.


Extract daemon config functions to daemon_config.go


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

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


Use -short flag in CI for PR checks

Update CI configuration to use -short flag for PR checks, run full tests nightly.

The slow tests already support testing.Short() and will be skipped.

Expected savings: ~20 seconds for PR checks (fast tests only)

Implementation:
- Update .github/workflows/ci.yml to add -short flag for PR tests
- Create/update nightly workflow for full test runs
- Update README/docs about test strategy

File: .github/workflows/ci.yml:30


Audit Current Cache Usage

**Summary:** Comprehensive audit of storage cache usage revealed minimal dependency across server components, with most calls following a consistent pattern. Investigation confirmed cache was largely unnecessary in single-repository daemon architecture.

**Key Decisions:**
- Remove all cache-related environment variables
- Delete server struct cache management fields
- Eliminate cache-specific test files
- Deprecate req.Cwd routing logic

**Resolution:** Cache system will be completely removed, simplifying server storage access and reducing unnecessary complexity with negligible performance impact.

AUDIT COMPLETE

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

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

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

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

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

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

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

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

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


Add sync resilience guardrails for forced pushes and prefix mismatches

Beads can get into unrecoverable sync states when remote forces pushes occur (e.g., rebases) combined with prefix mismatches from multi-worker scenarios. Add detection, prevention, and auto-recovery features to handle this gracefully.

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

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

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

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

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

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

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

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

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

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

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


Add fallback to polling on watcher failure

Makefile Integration for Benchmarks

Add a single 'bench' target to the Makefile for running performance benchmarks.

Target:
.PHONY: bench

bench:
	go test -bench=. -benchtime=3s -tags=bench \
		-cpuprofile=cpu.prof -memprofile=mem.prof \
		./internal/storage/sqlite/
	@echo ""
	@echo "Profiles generated. View flamegraph:"
	@echo "  go tool pprof -http=:8080 cpu.prof"

Features:
- Single simple target, no complexity
- Always generates CPU and memory profiles
- Clear output on how to view results
- 3 second benchmark time for reliable results
- Uses bench build tag for heavy benchmarks

Usage:
  make bench                              # Run all benchmarks
  go test -bench=BenchmarkGetReadyWork... # Run specific benchmark


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

Fix PR #319: Performance Improvements - CI failures and lint errors

PR #319 (Performance Improvements) has excellent performance optimizations but is blocked by CI failures.

## The PR
- URL: https://github.com/steveyegge/beads/pull/319
- Author: @rsnodgrass (Ryan)
- Claimed improvements: bd ready 20.5x faster (752ms → 36.6ms), startup 10.5x faster

## CI Failures

### Lint Errors (8 total)
1. cmd/bd/deletion_tracking.go:57 - unchecked os.Remove
2. cmd/bd/import.go:548 - unchecked os.RemoveAll
3. cmd/bd/message.go:205 - unchecked resp.Body.Close
4. cmd/bd/migrate_issues.go:633 - unchecked fmt.Scanln
5. cmd/bd/migrate_issues.go:701 - unchecked MarkFlagRequired
6. cmd/bd/migrate_issues.go:702 - unchecked MarkFlagRequired
7. cmd/bd/show.go:610 - gosec G104 unhandled error
8. cmd/bd/show.go:614 - gosec G104 unhandled error

### Test Failures
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"

This suggests the PR branch needs rebasing on current main.

## Required Work

### 1. Fix Lint Errors
Add proper error handling for all 8 flagged locations. Most can use _ = or log warnings.

### 2. Rebase on Current Main
The migration test failures indicate the branch is out of sync. Need to:
- git fetch upstream
- git rebase upstream/main
- Resolve any conflicts
- Verify tests pass locally

### 3. Verify CI Passes
- All lint checks green
- All tests pass (Linux, Windows, Nix)

## Optional Improvements
- Consider splitting into smaller PRs (core index, WASM cache, testing infra)
- Add documentation for benchmark usage
- Extract helper functions in doctor/perf.go for better testability

## Value
This PR delivers real performance improvements. The index optimization alone is worth merging quickly once CI is fixed.

Use in-memory filesystem for test git operations

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

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

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