YABB: Spurious issue updates during normal operations

Issue bd-627d was updated during config refactoring session without any actual changes to it. Only timestamps and content_hash changed.

Observed: Running various bd commands (list, create, etc.) caused bd-627d updated_at to change from 14:14 to 14:31.

Expected: Issues should only be updated when explicitly modified.

This causes:
- Dirty JSONL after every session
- False conflicts in git
- Confusing git history

Likely culprit: Daemon auto-import/export cycle or database migration touching all issues.

Investigated thoroughly - unable to reproduce. The import logic has IssueDataChanged() checks before calling UpdateIssue (importer/importer.go:458). All tests pass. May have been fixed by recent refactorings. Closing as cannot reproduce - please reopen with specific repro steps if it occurs again.


Add tests for helper functions (GetDirtyIssueHash, GetAllDependencyRecords, export hashes)

Several utility functions have 0% coverage:
- GetDirtyIssueHash (dirty.go)
- GetAllDependencyRecords (dependencies.go)
- GetExportHash, SetExportHash, ClearAllExportHashes (hash.go)

These are lower priority but should have basic coverage.


Blocked issue


Repair Commands & AI-Assisted Tooling

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

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

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


Don't search parent directories for .beads databases

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

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


Auto-repair stale merge driver configs with invalid placeholders

Old bd versions (<0.24.0) installed merge driver with invalid placeholders %L %R instead of %A %B. Add detection to bd doctor --fix: check if git config merge.beads.driver contains %L or %R, auto-repair to 'bd merge %A %O %A %B'. One-time migration for users who initialized with old versions.


Update bash-agent example with Agent Mail integration

Add Agent Mail integration to examples/bash-agent/agent.sh using curl for HTTP calls.

Acceptance Criteria:
- Health check function using curl
- Reserve issue before claiming
- Send notifications on status change
- Release on completion
- Graceful degradation if curl fails
- No bash errors when Agent Mail unavailable

File: examples/bash-agent/agent.sh


Pre-push hook and daemon export produce different JSONL

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

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

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

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

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

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

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


RPC fast-fail: stat socket before dial, cap timeouts to 200ms

Eliminate 5s delay when daemon socket is missing by:
1. Add os.Stat(socketPath) check before dialing in TryConnect
2. Return (nil, nil) immediately if socket doesn't exist
3. Set default dial timeout to 200ms in TryConnect
4. Keep TryConnectWithTimeout for explicit health/status checks (1-2s)

This prevents clients from waiting through full timeout when no daemon is running.


Fix silent error handling in RPC response writing

Marshal and write errors silently ignored in writeResponse, can send partial JSON and hang clients.

Location: internal/rpc/server_lifecycle_conn.go:228-232

Problem:
- json.Marshal error ignored - cyclic reference sends corrupt JSON
- Write error ignored - connection closed, no indication to caller
- WriteByte error ignored - client hangs waiting for newline
- Flush error ignored - partial data buffered

Current code:
func (s *Server) writeResponse(writer *bufio.Writer, resp Response) {
    data, _ := json.Marshal(resp)  // Ignored!
    _, _ = writer.Write(data)      // Ignored!
    _ = writer.WriteByte('\n')     // Ignored!
    _ = writer.Flush()             // Ignored!
}

Solution: Return errors, handle in caller, close connection on error

Impact: Client hangs waiting for response; corrupt JSON sent

Effort: 1 hour


bd doctor should check for multiple DBs, multiple JSONLs, daemon health


AI-supervised database migrations for safer schema evolution

## Problem

Database migrations can lose user data through edge cases that are hard to anticipate (e.g., GH #201 where bd migrate failed to set issue_prefix, or bd-d355a07d false positive data loss warnings). Since beads is designed to be run by AI agents, we should leverage AI to make migrations safer.

## Current State

Migrations run blindly with:
- No pre-flight validation
- No data integrity verification
- No rollback on failure
- Limited post-migration testing

Recent issues:
- GH #201: Migration didn't set issue_prefix config, breaking commands
- bd-d355a07d: False positive "data loss" warnings on collision resolution
- Users reported migration data loss (fixed but broader problem remains)

## Proposal: AI-Supervised Migration Framework

Use AI to supervise migrations through structured verification:

### 1. Pre-Migration Analysis
- AI reads migration code and current schema
- Identifies potential data loss scenarios
- Generates validation queries to verify assumptions
- Creates snapshot queries for before/after comparison

### 2. Migration Execution
- Take database backup/snapshot
- Run validation queries (pre-state)
- Execute migration in transaction
- Run validation queries (post-state)

### 3. Post-Migration Verification
- AI compares pre/post snapshots
- Verifies data integrity invariants
- Checks for unexpected data loss
- Validates config completeness (like issue_prefix)

### 4. Rollback on Anomalies
- If AI detects data loss, rollback transaction
- Present human-readable error report
- Suggest fix before retrying

## Example Flow

```
$ bd migrate

→ Analyzing migration plan...
→ AI identified 3 potential data loss scenarios
→ Generating validation queries...
→ Creating pre-migration snapshot...
→ Running migration in transaction...
→ Verifying post-migration state...
✓ All 247 issues accounted for
✓ Config table complete (issue_prefix: "mcp")
✓ Dependencies intact (342 relationships verified)
→ Migration successful!
```

If something goes wrong:
```
$ bd migrate

→ Analyzing migration plan...
→ AI identified issue: Missing issue_prefix config after migration
→ Recommendation: Add prefix detection step
→ Aborting migration - database unchanged
```

## Implementation Ideas

### A. Migration Validator Tool
Create `bd migrate --validate` that:
- Simulates migration on copy of database
- Uses AI to verify data integrity
- Reports potential issues before real migration

### B. Migration Test Generator
AI generates test cases for migrations:
- Edge cases (empty DB, large DB, missing config)
- Data integrity checks
- Regression tests

### C. Migration Invariants
Define invariants that AI checks:
- Issue count should not decrease (unless collision resolution)
- All required config keys present
- Foreign key relationships intact
- No orphaned dependencies

### D. Self-Healing Migrations
AI detects incomplete migrations and suggests fixes:
- Missing config values (like GH #201)
- Orphaned data
- Index inconsistencies

## Benefits

1. **Catch edge cases**: AI explores scenarios humans miss
2. **Self-documenting**: AI explains what migration does
3. **Agent-friendly**: Agents can run migrations confidently
4. **Fewer rollbacks**: Detect issues before committing
5. **Better testing**: AI generates comprehensive test suites

## Open Questions

1. Which AI model? (Fast: Haiku, Thorough: Sonnet/GPT-4)
2. How to balance safety vs migration speed?
3. Should AI validation be required or optional?
4. How to handle offline scenarios (no API access)?
5. What invariants should always be checked?

Fix Homebrew warning about Ruby file location

Homebrew warning: Found Ruby file outside steveyegge/beads tap formula directory.
Warning points to: /opt/homebrew/Library/Taps/steveyegge/homebrew-beads/bd.rb
It should likely be inside a Formula/ directory or similar structure expected by Homebrew taps.


Add concurrent import race condition tests

Currently no tests verify behavior when multiple clones import simultaneously with external_ref matching.

Scenarios to test:
1. Two clones import same external_ref update at same time
2. Clone A imports while Clone B updates same issue
3. Verify transaction isolation prevents corruption
4. Document expected behavior (last-write-wins vs timestamp-based)

Enhance dep tree to show full dependency graph

When running `bd dep tree <issue-id>`, the current output only shows the issue itself without its dependency relationships.

## Current Behavior

```
$ bd dep tree gt-0iqq
🌲 Dependency tree for gt-0iqq:

→ gt-0iqq: Implement Boss (global overseer) [P2] (open)
```

This doesn't show any of the dependency structure.

## Desired Behavior

Show the full dependency DAG rooted at the given issue. For example:

```
$ bd dep tree gt-0iqq
🌲 Dependency tree for gt-0iqq:

gt-0iqq: Implement Boss (global overseer) [P2] (open)
├── gt-0xh4: Boss session management [P2] (open) [READY]
│   ├── gt-le7c: Boss mail identity [P2] (open)
│   │   ├── gt-r8fe: Boss human escalation queue [P2] (open)
│   │   └── gt-vdak: Boss dispatch loop [P2] (open)
│   │       └── gt-kgy6: Boss resource management [P2] (open)
│   │           └── gt-93iv: Boss wake daemon [P2] (open)
│   └── gt-vdak: (shown above)
```

## Suggested Options

- `--direction=down|up|both` - Show dependents (what this blocks), dependencies (what blocks this), or both
- `--status=open` - Filter to only show issues with a given status
- `--depth=N` - Limit tree depth
- Handle DAG cycles gracefully (show "(shown above)" or similar for already-displayed nodes)

## Use Case

When reorganizing a set of related issues (like I just did with the Boss implementation), being able to visualize the full dependency graph helps verify the structure is correct before syncing.


Update AGENTS.md with Agent Mail workflow

Update agent workflow section to include Agent Mail coordination as optional step.

Acceptance Criteria:
- Add Agent Mail to recommended workflow
- Show both with/without examples

- Cross-reference to AGENT_MAIL.md

File: AGENTS.md (lines 468-475)


Sync should cleanup snapshot files after completion

After sync completion, orphan .base.jsonl and .left.jsonl snapshot files remain in .beads/ directory. These should be cleaned up on successful sync.


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

## Problem

`checkGitHistoryForDeletions` assumes the repo structure:

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

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

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

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

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

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

PushSyncBranch may fail if worktree was cleaned up


Add WaitGroup tracking to FileWatcher goroutines

FileWatcher spawns goroutines without WaitGroup tracking, causing race condition on shutdown.

Location: cmd/bd/daemon_watcher.go:123-182, 215-291

Problem:
- Goroutines spawned without sync.WaitGroup
- Close() cancels context but doesn't wait for goroutines to exit
- Race condition: goroutine may access fw.debouncer during Close() cleanup
- No guarantee goroutine stopped before fw.watcher.Close() is called

Solution:
- Add sync.WaitGroup field to FileWatcher
- Track goroutines with wg.Add(1) and defer wg.Done()
- Call wg.Wait() in Close() before cleanup

Impact: Race condition on daemon shutdown; potential panic

Effort: 2 hours


bd-hv01: Silent partial deletion failures cause DB inconsistency

Problem: deletion_tracking.go:76-77 logs deletion errors as warnings but continues. If deletion fails midway (database locked, disk full), some issues delete but others don't. System thinks all deletions succeeded.

Impact: Database diverges from JSONL, silent corruption, issues may resurrect on next sync.

Fix: Collect errors and fail the operation:
var deletionErrors []error
for _, id := range acceptedDeletions {
    if err := d.DeleteIssue(ctx, id); err != nil {
        deletionErrors = append(deletionErrors, fmt.Errorf("issue %s: %w", id, err))
    }
}
if len(deletionErrors) > 0 {
    return false, fmt.Errorf("deletion failures: %v", deletionErrors)
}

Refactor: deduplicate FindJSONLInDir and FindJSONLPath

## Background

After fixing bd-tqo, we now have two nearly identical functions for finding the JSONL file:
- `autoimport.FindJSONLInDir(dbDir string)` in internal/autoimport/autoimport.go
- `beads.FindJSONLPath(dbPath string)` in internal/beads/beads.go

Both implement the same logic:
1. Prefer issues.jsonl
2. Fall back to beads.jsonl for legacy support
3. Skip deletions.jsonl and merge artifacts
4. Default to issues.jsonl if nothing found

## Problem

Code duplication means bug fixes need to be applied in multiple places (as we just experienced with bd-tqo).

## Proposed Solution

Extract shared logic to a utility package that both can import. Options:
1. Create `internal/jsonlpath` package with the core logic
2. Have `autoimport` import `beads` and call `FindJSONLPath` (but APIs differ slightly)
3. Move to `internal/utils` if appropriate

Need to verify no import cycles would be created.

## Affected Files
- internal/autoimport/autoimport.go
- internal/beads/beads.go


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


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.


Sync branch integrity guards

Track sync branch parent commit. If sync branch was force-pushed, warn user and require confirmation before proceeding. Add option to reset to remote if user accepts rebase. Prevents silent corruption from forced pushes.


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

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

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

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

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


Remove misleading placeholder 'bd merge' command from duplicates output

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

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

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

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

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

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

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


Issue to reopen with reason

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


Document sync.require_confirmation_on_mass_delete config option


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

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

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

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


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


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

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

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

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

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

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


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


Integrate beads-merge tool by @neongreen

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

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

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

**Integration options**:

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

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

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

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

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

Next: Wait for response before proceeding with integration.

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

Next: Vendor beads-merge with full attribution


Add TestThreeCloneCollision for regression protection

Add a 3-clone collision test to document behavior and provide regression protection.

Purpose:
- Verify content convergence regardless of sync order
- Document the ID non-determinism behavior (IDs may be assigned differently based on sync order)
- Provide regression protection for multi-way collisions

Test design:
- 3 clones create same ID with different content
- Test two different sync orders (A→B→C vs C→A→B)
- Assert content sets match (ignore specific ID assignments)
- Add comment explaining ID non-determinism is expected behavior

Known limitation:
- Content always converges correctly (all issues present with correct titles)
- Numeric ID assignments (test-2 vs test-3) depend on sync order
- This is acceptable if content convergence is the primary goal


Pre-sync integrity check (bd sync --check)

Add bd sync --check flag that detects problematic states before attempting sync: forced pushes on sync branch (via git reflog), prefix mismatches in JSONL, orphaned children with missing parents. Output combined diagnostic without modifying state.


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

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

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

Estimated effort: 4-5 days

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


Fix gosec lint warnings in doctor.go, main.go, and fix subdirectory

CI lint job failing with 4 gosec warnings:
- cmd/bd/doctor.go:664 (G304: file inclusion via variable)
- cmd/bd/doctor/fix/database_config.go:166 (G304: file inclusion via variable)
- cmd/bd/doctor/fix/untracked.go:61 (G204: subprocess launched with variable)
- cmd/bd/main.go:645 (G304: file inclusion via variable)

Either suppress with `// #nosec` if false positives, or refactor to validate paths properly.


Investigate jujutsu VCS as potential solution for conflict-free merging

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

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

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

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

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

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

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


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

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

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

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

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

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

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

This is CRITICAL - main should never have breaking tests.

Sync protection mechanism resurrects deleted issues

During bd sync, the 'Protecting N issue(s) from left snapshot' logic resurrects issues that are in the deletions manifest, causing UNIQUE constraint failures on subsequent syncs.

## Reproduction
1. Delete an issue with bd delete (creates tombstone + deletions.jsonl entry)
2. Run bd sync - succeeds
3. Run bd sync again - fails with 'UNIQUE constraint failed: issues.id'

## Root Cause
The protection mechanism (designed to prevent data loss during 3-way merge) keeps a snapshot of issues before sync. When importing after pull, it restores issues from this snapshot even if they're in the deletions manifest.

## Observed Behavior
- bd-3pd was deleted and added to deletions.jsonl
- First sync exports tombstone, commits, pulls, imports - succeeds
- Second sync: protection restores bd-3pd from left snapshot
- Import tries to create bd-3pd which already exists → UNIQUE constraint error

## Expected Behavior
Issues in deletions manifest should NOT be restored by protection mechanism.

## Workaround
Manually delete from DB: sqlite3 .beads/beads.db 'DELETE FROM issues WHERE id = "bd-xxx"'

## Files to Investigate
- cmd/bd/sync.go - protection logic
- cmd/bd/snapshot_manager.go - left snapshot handling
- internal/importer/importer.go - import with protection

Fix TestTwoCloneCollision to compare content not timestamps

The test at beads_twoclone_test.go:204-207 currently compares full JSON output including timestamps, causing false negative failures.

Current behavior:
- Both clones converge to identical semantic content
- Clone A: test-2="Issue from clone A", test-1="Issue from clone B"
- Clone B: test-1="Issue from clone B", test-2="Issue from clone A"
- Titles match IDs correctly, no data corruption
- Only timestamps differ (expected and acceptable)

Fix needed:
- Replace exact JSON comparison with content-aware comparison
- Normalize or ignore timestamp fields when asserting convergence
- Test should PASS after this fix

This blocks completion of bd-71107098.


Implement hash ID generation in CreateIssue

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

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

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

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

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

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

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

Recommended: Option 3 (git remote hash) for reproducibility

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

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

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


Fix transaction conflict in TryResurrectParent

Integration test TestImportWithDeletedParent fails with 'database is locked' error when resurrection happens inside CreateIssue.

Root cause: TryResurrectParent calls conn.Get() and insertIssue() which conflicts with existing transaction in CreateIssue.

Error: failed to create tombstone for parent bd-parent: failed to insert issue: sqlite3: database is locked

Solution: Refactor resurrection to accept optional transaction parameter, use existing transaction when available instead of creating new connection.

Impact: Blocks resurrection from working in CreateIssue flow, only works in EnsureIDs (which may not have active transaction).


Batch test 5


Tombstone export includes tombstones even with --status filter

In export.go, we set IncludeTombstones: true unconditionally. However, if a user runs:

  bd export --status=open

They might not expect tombstones in the output. The IncludeTombstones flag should probably only be set when no status filter is specified, or when --status=tombstone is explicitly requested.

Current behavior: exports tombstones regardless of status filter
Expected behavior: respect status filter, only include tombstones when explicitly requested or no filter


Fix bd init to bootstrap from sync-branch when configured

When sync-branch is configured in config.yaml, bd init should import from that branch instead of HEAD. Currently it reads HEAD:.beads/issues.jsonl which may be empty or stale when issues are on the sync branch. Location: cmd/bd/autoimport.go:97 checkGitForIssues()


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

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

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

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

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

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

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

## Progress Update

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

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

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

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

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

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

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


Update docs for import bug fix

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


Duplicate DefaultRetentionDays constants

## Problem

There are now two constants for the same value:

1. `deletions.DefaultRetentionDays = 7` in `internal/deletions/deletions.go:184`
2. `configfile.DefaultDeletionsRetentionDays = 7` in `internal/configfile/configfile.go:102`

## Impact
- DRY violation
- Risk of values getting out of sync
- Confusing which one to use

## Fix
Remove the constant from `deletions` package and have it import from `configfile`, or create a shared constants package.


Batch test 3


Make MCP compaction settings configurable (COMPACTION_THRESHOLD, PREVIEW_COUNT)

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

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

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

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

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


Add .beads/README.md during 'bd init' for project documentation and promotion

When 'bd init' is run, automatically generate a .beads/README.md file that:

1. Briefly explains what Beads is (AI-native issue tracking that lives in your repo)
2. Links to the main repository: https://github.com/steveyegge/beads
3. Provides a quick reference of essential commands:
   - bd create: Create new issues
   - bd list: View all issues
   - bd update: Modify issue status/details
   - bd show: View issue details
   - bd sync: Sync with git remote
4. Highlights key benefits for AI coding agents and developers
5. Encourages developers to try it out

The README should be enthusiastic and compelling to get open source contributors excited about using Beads for their AI-assisted development workflows.


Document deletions manifest in AGENTS.md and README

Parent: bd-imj

## Task
Add documentation about the deletions manifest feature.

## Locations to Update

### AGENTS.md
- Explain that deletions.jsonl is tracked in git
- Document that `bd delete` records to the manifest
- Explain cross-clone propagation mechanism

### 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


Test graceful degradation when server unavailable

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

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

Success Metric: Zero functional difference when Agent Mail unavailable


Parameterize SQLite busy_timeout in store.go

Modify sqlite.New() to accept configurable busy_timeout.

## Current State
`internal/storage/sqlite/store.go` hardcodes:
```go
connStr = "file:" + path + "?_pragma=foreign_keys(ON)&_pragma=busy_timeout(30000)&..."
```

## Implementation Options

### Option A: Add timeout parameter to New()
```go
func New(ctx context.Context, path string, busyTimeout time.Duration) (*SQLiteStorage, error)
```
Pro: Simple, explicit
Con: Changes function signature (breaking change for callers)

### Option B: Options struct pattern
```go
type Options struct {
    BusyTimeout time.Duration // default 30s
}
func New(ctx context.Context, path string, opts *Options) (*SQLiteStorage, error)
```
Pro: Extensible, nil means defaults
Con: More boilerplate

### Recommendation: Option A with default
```go
func New(ctx context.Context, path string) (*SQLiteStorage, error) {
    return NewWithOptions(ctx, path, 30*time.Second)
}

func NewWithOptions(ctx context.Context, path string, busyTimeout time.Duration) (*SQLiteStorage, error)
```

## Acceptance Criteria
- busy_timeout is parameterized in connection string
- 0 timeout means no waiting (immediate SQLITE_BUSY)
- All existing callers continue to work (via default wrapper)

Event-driven daemon architecture

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

Production-ready after 3 critical fixes (commit 349b892):
- Skip redundant imports (mtime check prevents self-trigger loops)
- Add server.Stop() in serverErrChan case (clean shutdown)
- Fallback ticker (60s) when watcher unavailable (ensures remote sync)

Ready to make default after integration test (bd-1f4086c5.1) passes.


Fix G304 potential file inclusion in cmd/bd/tips.go:259

Linting issue: G304: Potential file inclusion via variable (gosec) at cmd/bd/tips.go:259:18. Error: if data, err := os.ReadFile(settingsPath); err == nil {


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

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


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


Auto-migrate database on CLI version bump

When CLI is upgraded (e.g., 0.24.0 → 0.24.1), database version becomes stale. Add auto-migration in PersistentPreRun or daemon startup. Check dbVersion != CLIVersion and run bd migrate automatically. Fixes recurring UX issue where bd doctor shows version mismatch after every CLI upgrade.


GH#508: Orphan detection false positive when directory name contains dot

Directory names with dots trigger orphan issue detection because dot is also used for orphan ID format. bd rename-prefix fixes it. See: https://github.com/steveyegge/beads/issues/508


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.


bd sync --squash: batch multiple syncs into single commit

For solo developers who don't need real-time multi-agent coordination, add a --squash option to bd sync that accumulates changes and commits them in a single commit rather than one commit per sync.

This addresses the git history pollution concern (many 'bd sync: timestamp' commits) while preserving the default behavior needed for orchestration.

**Proposed behavior:**
- `bd sync --squash` accumulates pending exports without committing
- Commits accumulated changes on session end or explicit `bd sync` (without --squash)
- Default behavior unchanged (immediate commits for orchestration)

**Use case:** Solo developers who want cleaner git history but don't need real-time coordination between agents.

**Related:** PR #411 (docs: reduce bd sync commit pollution)
**See also:** Multi-repo support as alternative solution (docs/MULTI_REPO_AGENTS.md)


Use stable repo identifiers instead of full paths in metadata keys

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

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

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

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

## Related
Depends on bd-ar2.10 (hasJSONLChanged update)


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

## Problem

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

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

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

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

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

## Fix
Escape regex special characters:

```go
import "regexp"

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


Document shared memory test isolation pattern in test_helpers.go

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

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


Add comprehensive tests for sync branch daemon logic

The daemon sync branch functionality (bd-6545) was implemented but needs proper end-to-end testing.

Current implementation:
- daemon_sync_branch.go has syncBranchCommitAndPush() and syncBranchPull()
- daemon_sync.go has been updated to use these functions when sync.branch is configured
- All daemon tests pass, but no specific tests for sync branch behavior

Testing needed:
- Test that daemon commits to sync branch when sync.branch is configured
- Test that daemon commits to current branch when sync.branch is NOT configured (backward compatibility)
- Test that daemon pulls from sync branch and syncs JSONL back to main repo
- Test worktree creation and health checks during daemon operations
- Test error handling (missing branch, worktree corruption, etc.)

Key challenge: Tests need to run in the context of the git repo (getGitRoot() uses current working directory), so test setup needs to properly change directory or mock the git root detection.

Reference existing daemon tests in daemon_test.go and daemon_autoimport_test.go for patterns.


Fragile no-db detection uses strings.Contains instead of YAML parsing

Two locations use `strings.Contains(string(configData), "no-db: true")` to detect JSONL-only mode:

1. **cmd/bd/main.go:310** - Auto-enabling no-db mode
2. **cmd/bd/doctor.go:863** - Database status check

This is fragile because it could match:
- Comments: `# no-db: true for testing`
- Nested keys: `settings:\n  no-db: true`
- String values: `note: "set no-db: true to disable"`

Should use proper YAML parsing like we did for sync-branch in bd-0rh:

```go
type noDbConfig struct {
    NoDb bool `yaml:"no-db"`
}

var cfg noDbConfig
if err := yaml.Unmarshal(configData, &cfg); err == nil {
    isNoDbMode = cfg.NoDb
}
```

Add programmatic tip injection API

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


purgeDeletedIssues still writes to deletions.jsonl during git-history-backfill

In purgeDeletedIssues (lines 929-939), when a deletion is recovered from git history, we:
1. Append to deletions.jsonl (backfill)
2. Create a tombstone in DB

With the tombstone approach, writing to deletions.jsonl is redundant since the tombstone will be exported to JSONL. Consider removing the deletions.jsonl backfill once we're confident in the tombstone approach.

This is related to the Phase 2 migration (bd-vw8) - we should stop writing to deletions.jsonl entirely.


Fix: bd migrate-tombstones corrupts deletions manifest

When running 'bd migrate-tombstones' followed by 'bd sync', the operation adds thousands of issues to deletions.jsonl with author 'bd-doctor-hydrate' that should never have been deleted. This causes:
1. Issues are marked as deleted that were never intended for deletion
2. Subsequent 'bd sync' fails with 3-way merge errors
3. The migration operation corrupts database state

## Root Cause
The tombstone migration logic incorrectly identifies issues that should be migrated as 'deleted issues' and adds them to the deletions manifest instead of converting them to inline tombstones.

## Reproduction
1. bd sync --import-only
2. bd migrate-tombstones
3. bd sync
Result: See thousands of 'Skipping bd-xxxx (in deletions manifest: deleted 2025-12-14 by bd-doctor-hydrate)' lines and 3-way merge failures

## Impact
- Database becomes inconsistent
- Issues permanently lost from local database
- Requires full reset to recover

## Files to Investigate
- cmd/bd/migrate_tombstones.go - migration logic
- deletions manifest handling during migration


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

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

## The Problem

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

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

## Proposed Behavior

```
$ bd init --prefix bd

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

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

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

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

Aborting.
```

## Trigger Conditions

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

## Edge Cases

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

## Related

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

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


Fix failing integration tests in beads-mcp

The `beads-mcp` test suite has failures in `tests/test_bd_client_integration.py` (assertion error in `test_init_creates_beads_directory`) and errors in `tests/test_worktree_separate_dbs.py` (setup failures finding database). These need to be investigated and fixed to ensure a reliable CI baseline.


Invert control for compact: provide tools for agent-driven compaction

Currently compact requires Anthropic API key because bd calls the AI directly. This is backwards - we should provide tools (like all other bd commands) that let an AI agent perform the compaction. The agent decides what to keep/merge, not bd. Related to GH #243 complaint about API key requirement.


Config option sync.require_confirmation_on_mass_delete

Add config option for paranoid users who want confirmation before pushing after mass deletion.

- Show them what would be pushed

For users who have been burned and want extra safety. Most users will not need this.

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

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

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

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

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

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

Fix TestTwoCloneCollision timeout


Tombstone import creates duplicate entries when deletions.jsonl has entries already in JSONL

In the tombstone import logic (bd-dve), when a non-tombstone issue is in both JSONL and deletions.jsonl, we:
1. Skip the issue (line 149-155)
2. Create a tombstone from deletions.jsonl (lines 161-171)

This means if the JSONL contains issue 'bd-abc' (non-tombstone) and deletions.jsonl also has 'bd-abc', we skip the JSONL version but then add a tombstone version from deletions.jsonl. This is intentional but the skipped issue count may be confusing.

Consider: should we track converted-to-tombstone separately from skipped-deleted in the Result struct?


Fix row iterator resource leak in recursive dependency queries

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

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

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

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

Impact: Connection exhaustion during dependency traversal


Jira import/export integration

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

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

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

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

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

Fixture Generator for Realistic Test Data

Create internal/testutil/fixtures/fixtures.go with functions to generate realistic test data at scale.

Functions:
- LargeSQLite(storage) - 10K issues, native SQLite
- XLargeSQLite(storage) - 20K issues, native SQLite
- LargeFromJSONL(storage) - 10K issues imported from JSONL
- XLargeFromJSONL(storage) - 20K issues imported from JSONL

## Note
- May need to choose different name if @beads namespace unavailable
- Alternative: beads-cli, bd-cli, or unscoped beads-issue-tracker


bd sync corrupts issues.jsonl in multi-clone environments

During parallel swarm operations on 2025-11-29, bd sync corrupted the issues database. Commit 93718056 purged all 80 issues from issues.jsonl.

Reproduction:
1. Multiple clones of same repo (polecat swarm)
2. Each clone runs bd sync in parallel
3. One sync overwrites others, resulting in data loss

Even in single-clone scenarios (~/src/beads), running bd sync after git pull seems to nuke the JSONL.

Workaround: Use bd import -i .beads/issues.jsonl --no-git-history instead of bd sync.

Root cause investigation needed. Options:
1. Pessimistic locking (flock)
2. Single point of merge (polecats on ephemeral branches)
3. Beads-level locking (bd sync --lock)

Performance Validation

Confirm no performance regression from cache removal


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.


Run final validation and cleanup checks

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

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

Final metrics to report:
- LOC removed: ~____
- Files deleted: ____
- Files created: ____
- Test coverage: ____%
- Build time: ____ (before/after)
- Test run time: ____ (before/after)

Impact: Confirms all cleanup objectives achieved successfully

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

Fix autoimport tests for content-hash collision scoring

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

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

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

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

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

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

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

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


Benchmark Helper Functions

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

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

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

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

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

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

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


Add command injection prevention tests for git rm in merge command

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

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

In cmd/bd/merge.go:121, exec.Command is called with variable fullPath, flagged by gosec G204 for potential command injection.

Add tests covering:
- File paths with shell metacharacters (;, |, &, $, etc.)
- Paths with spaces and special characters
- Paths attempting command injection (e.g., 'file; rm -rf /')
- Validation that fullPath is properly sanitized
- Only valid git-tracked files can be removed

This is a critical security path preventing arbitrary command execution.

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

Add database maintenance commands section to QUICKSTART.md

**Problem:**
Users don't discover `bd compact` or `bd cleanup` commands until their database grows large. These maintenance commands aren't mentioned in quickstart documentation.

Related to issue #349 item #4.

**Current state:**
docs/QUICKSTART.md ends at line 217 with "See README.md for full documentation" but has no mention of maintenance operations.

**Proposed addition:**
Add a "Database Maintenance" section after line 140 (before "Advanced: Agent Mail" section) covering:
- When database grows (many closed issues)
- How to view compaction statistics
- How to compact old issues
- How to delete closed issues
- Warning about permanence

**Example content:**
```markdown
## Database Maintenance

As your project accumulates closed issues, the database grows. Use these commands to manage size:

```bash
# View compaction statistics
bd compact --stats

# Preview compaction candidates (30+ days closed)
bd compact --analyze --json

# Apply agent-generated summary
bd compact --apply --id bd-42 --summary summary.txt

# Immediately delete closed issues (use with caution!)
bd cleanup --force
```

**When to compact:**
- Database file > 10MB with many old closed issues
- After major project milestones
- Before archiving a project phase
```

**Files to modify:**
- docs/QUICKSTART.md (add section after line 140)


Document 3-clone ID non-determinism in collision resolution

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

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

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


Improve clean vs cleanup command naming/documentation

Clarify the difference between bd clean and bd cleanup to reduce user confusion.

**Current state:**
- bd clean: Remove temporary artifacts (.beads/bd.sock, logs, etc.)
- bd cleanup: Delete old closed issues from database

**Options:**
1. Rename for clarity:
   - bd clean → bd clean-temp
   - bd cleanup → bd cleanup-issues

2. Keep names but improve help text and documentation

3. Add prominent warnings in help output

**Preferred approach:** Option 2 (improve documentation)
- Update short/long descriptions in commands
- Add examples to help text
- Update README.md
- Add cross-references in help output

**Files to modify:**
- cmd/bd/clean.go
- cmd/bd/cleanup.go
- README.md or ADVANCED.md

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

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

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

This fixes GitHub issue #274 reported by rscorer.


Investigate and upgrade to modernc.org/sqlite 1.39.1+

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

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

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

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

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

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

Add index usage verification test for external_ref lookups

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

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

Add multi-repo support to export metadata updates

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

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

But metadata updates are missing!

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

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

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

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

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

Comprehensive test to verify hash IDs eliminate collision problems.

## Test: TestHashIDsNClones

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

### Edge Case Tests

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

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

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

### Performance Test

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

// Expected: < 1μs per generation
```

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

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

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

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

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

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

Current state:
- 2-clone collision resolution is SOUND and working correctly
- Hash-based deterministic collision resolution works
- Test fails due to timestamp comparison, not actual logic issues

Work needed:
1. Fix TestTwoCloneCollision to compare content not timestamps
2. Add TestThreeCloneCollision for regression protection
3. Document 3-clone ID non-determinism as known behavior


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

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

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

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

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

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

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

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

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

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


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


Implement health checks in daemon event loop

Add health checks to checkDaemonHealth() function in daemon_event_loop.go:170:
- Database integrity check
- Disk space check
- Memory usage check

Currently it's just a no-op placeholder.


Final validation test


Implement tombstone types and schema migration

Add tombstone fields to Issue struct (deleted_at, deleted_by, delete_reason, original_type), add StatusTombstone constant, create SQLite migration for new columns. Per design bd-2m7.


Import overwrites newer local issues with older remote versions

## Problem

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

## What Happened

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

## Root Cause

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

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

Import applies incoming version regardless of which is newer.

## Expected Behavior

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

## Solution

Add timestamp checking to DetectCollisions or importIssues:

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

Audit and consolidate collision test coverage

The codebase has 2,019 LOC of collision detection tests across 3 files. Run coverage analysis to identify redundant test cases and consolidate.

Test files:
- `cmd/bd/import_collision_test.go` - 974 LOC
- `cmd/bd/autoimport_collision_test.go` - 750 LOC
- `cmd/bd/import_collision_regression_test.go` - 295 LOC

Total: 2,019 LOC of collision tests

Analysis steps:
1. Run coverage analysis
2. Identify redundant tests
3. Document findings

Consolidation strategy:
- Keep regression tests for critical bugs
- Merge overlapping table-driven tests
- Remove redundant edge case tests covered elsewhere
- Ensure all collision scenarios still tested

Expected outcome: Reduce to ~1,200 LOC (save ~800 lines) while maintaining coverage

Impact: Faster test runs, easier maintenance, clearer test intent


Merge timestamp tie-breaker should prefer local (left)

In mergeFieldByUpdatedAt, when timestamps are exactly equal, right wins. For consistency with IssueType (where local/left wins), equal timestamps should prefer left. Minor inconsistency.


Add date and priority filters to bd search

Add filter parity with bd list for consistent querying.

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

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

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


Investigation & Proof of Concept

- Optional/non-intrusive integration approach validated

Next: bd-wfmw (Integration Layer 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

Clarify .beads/.gitattributes handling in Protected Branches docs

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


Investigate jujutsu integration for beads

Research and document how beads could integrate with jujutsu (jj), the next-generation VCS. Key areas to explore:
- How jj's operation model differs from git (immutable operations, working-copy-as-commit)
- JSONL sync strategy with jj's conflict resolution model
- Daemon compatibility with jj's more frequent rewrites
- Whether auto-import/export needs changes for jj workflows
- Example configurations and documentation updates needed


Code Review Sweep: thorough

Perform thorough code review sweep based on accumulated activity.

**AI Reasoning:**
Significant code activity with 7608 lines added and 120 files changed indicates substantial modifications. Multiple high-churn areas (cmd/bd, internal/rpc) suggest potential for subtle issues and emerging patterns that warrant review.

**Scope:** thorough
**Target Areas:** cmd/bd, internal/rpc, .beads

Implement core reset package (internal/reset)

Create the core reset logic in internal/reset/ package.

## Responsibilities
- ResetOptions struct with all flag options
- CountImpact() - count issues/tombstones that will be deleted
- ValidateState() - check .beads/ exists, check git dirty state
- ExecuteReset() - main reset logic (without CLI concerns)
- Integrate with daemon killall

## Interface Design
```go
type ResetOptions struct {
    Hard      bool   // Include git operations (git rm, commit)
    Backup    bool   // Create backup before reset
    DryRun    bool   // Preview only, don't execute
    SkipInit  bool   // Don't re-initialize after reset
}

type ResetResult struct {
    IssuesDeleted     int
    TombstonesDeleted int
    BackupPath        string  // if backup was created
    DaemonsKilled     int
}

type ImpactSummary struct {
    IssueCount      int
    OpenCount       int
    ClosedCount     int
    TombstoneCount  int
    HasUncommitted  bool  // git dirty state
}

func Reset(opts ResetOptions) (*ResetResult, error)
func CountImpact() (*ImpactSummary, error)
func ValidateState() error
```

## IMPORTANT: CLI vs Core Separation
- `Force` (skip confirmation) is NOT in ResetOptions - that's a CLI concern
- Core always executes when called; CLI decides whether to prompt first
- Keep CLI-agnostic: no prompts, no colored output, no user interaction
- Return errors for CLI to handle with user-friendly messages
- Unit testable in isolation

## Dependencies
- Uses daemon.KillAllDaemons() from internal/daemon/
- Calls bd init logic after reset (unless SkipInit)
