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.


Fix autoimport tests for content-hash collision scoring

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

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

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

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

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

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

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

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


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.


Implement transaction retry logic for SQLITE_BUSY

BEGIN IMMEDIATE fails immediately on SQLITE_BUSY instead of retrying with exponential backoff.

Location: internal/storage/sqlite/sqlite.go:223-225

Problem:
- Under concurrent write load, BEGIN IMMEDIATE can fail with SQLITE_BUSY
- Current implementation fails immediately instead of retrying
- Results in spurious failures under normal concurrent usage

Solution: Implement exponential backoff retry:
- Retry up to N times (e.g., 5)
- Backoff: 10ms, 20ms, 40ms, 80ms, 160ms
- Check for context cancellation between retries
- Only retry on SQLITE_BUSY/database locked errors

Impact: Spurious failures under concurrent write load

Effort: 3 hours


Test Agent Mail server failure scenarios

Verify graceful degradation across various failure modes.

Test Cases:
- Server never started
- Server crashes during operation
- Network partition (timeout)
- Server returns 500 error
- Invalid bearer token
- SQLite corruption

Acceptance Criteria:
- Agents continue working in all scenarios
- Clear log messages about degradation
- No crashes or data loss
- Beads JSONL remains consistent

File: tests/integration/test_mail_failures.py


Implement topological sort for import ordering

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


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)


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.


bd sync false positive: conflict detection triggers on JSON-encoded angle brackets in issue content

The bd sync --import-only command incorrectly detects conflict markers when issue descriptions contain the text '<<<<<<<' or '>>>>>>>' as legitimate content (e.g., documentation about git conflict markers).

**Reproduction:**
1. Create issue with design field containing: 'Read file, extract <<<<<<< / ======= / >>>>>>> markers'
2. Export to JSONL (gets JSON-encoded as \u003c\u003c\u003c...)
3. Commit and push
4. Pull from remote
5. bd sync --import-only fails with: 'Git conflict markers detected in JSONL file'

**Root cause:**
The conflict detection appears to decode JSON before checking for conflict markers, causing false positives when issue content legitimately contains these strings.

**Expected behavior:**
Conflict detection should only trigger on actual git conflict markers (literal '<<<<<<<' bytes in the raw file), not on JSON-encoded content within issue fields.

**Test case:**
VC project at ~/src/dave/vc has vc-85 'JSONL Conflict Parser' which documents conflict parsing and triggers this bug.

**Suggested fixes:**
1. Only scan for literal '<<<<<<<' bytes (not decoded JSON content)
2. Parse JSONL first and only flag unparseable lines
3. Check git merge state (git status) to confirm actual conflict
4. Add --skip-conflict-check flag for override


False positive detection by Kaspersky Antivirus (Trojan)

Kaspersky Antivirus falsely detects beads (bd.exe v0.23.1) as a Trojan (PDM:Trojan.Win32.Generic) and removes it.
Event: Malicious object detected
Component: System Watcher
Object name: bd.exe


Add LastBdVersion field to Config struct


Add orphan detection migration

Create migration to detect orphaned children in existing databases. Query: SELECT id FROM issues WHERE id LIKE '%.%' AND substr(id, 1, instr(id || '.', '.') - 1) NOT IN (SELECT id FROM issues). Log results, let user decide action (delete orphans or convert to top-level).


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.


Implement bd upgrade subcommand with status/review/ack


Issue with labels


Issue 2 to reopen


Test parent issue


Support local-only git repos without remote origin

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


Clean up snapshot files after successful merge

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

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

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

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

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

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

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


Test child daemon mode


Add parent issue existence validation in create.go direct mode

**Location:** cmd/bd/create.go:177-185

**Issue:** When creating child issues in direct mode (daemon not running), code calls GetNextChildID() without validating parent issue exists first.

**Current Code:**
```go
if parentID != "" && daemonClient == nil {
    childID, err := store.GetNextChildID(ctx, parentID)
    // No check: does parentID exist?
}
```

**Impact:** Could create orphaned child issues pointing to non-existent parents, causing data integrity issues.

**Fix:** Add existence check before generating child ID:
```go
parentIssue, err := store.GetIssue(ctx, parentID)
if err != nil {
    fmt.Fprintf(os.Stderr, "Error: parent issue %s not found\n", parentID)
    os.Exit(1)
}
```


Add tests for daemon lifecycle module


Add BEADS_DAEMON_MODE flag handling

Add environment variable BEADS_DAEMON_MODE (values: poll, events). Default to 'poll' for Phase 1. Wire into daemon startup to select runEventLoop vs runEventDrivenLoop.


bd resolve-conflicts - Git merge conflict resolver

Automatically resolve JSONL merge conflicts.

Modes:
- Mechanical: ID remapping (no AI)
- AI-assisted: Smart merge/keep decisions
- Interactive: Review each conflict

Handles <<<<<<< conflict markers in .beads/beads.jsonl

Files: cmd/bd/resolve_conflicts.go (new)


Test FK constraint via close


Add 'bd comment' as alias for 'bd comments add'

The command 'bd comments add' is verbose and unintuitive. Add 'bd comment' as a shorter alias that works the same way.

## Rationale
- More natural: 'bd comment <issue-id> <text>' reads better than 'bd comments add <issue-id> <text>'
- Matches user expectations: users naturally try 'bd comment' first
- Follows convention: other commands like 'bd create', 'bd show', 'bd close' are verbs

## Implementation
Could be implemented as:
1. A new command that wraps bd comments add
2. An alias registered in cobra
3. Keep 'bd comments add' for backwards compatibility

## Examples
```bash
bd comment bd-1234 'This is a comment'
bd comment bd-1234 'Multi-line comment' --body 'Additional details here'
```


Document bd edit command and verify MCP exclusion

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


Add test coverage for internal/git package


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

Related: #262


Improve compact/daemon/merge documentation and UX

Multiple documentation and UX issues encountered:
1. "bd compact --analyze" fails with misleading "requires SQLite storage" error when daemon is running. Needs --no-daemon or better error.
2. "bd merge" help text is outdated (refers to 3-way merge instead of issue merging).
3. Daemon mode purpose isn't clear to local-only users.
4. Compact/cleanup commands are hard to discover.

Proposed fixes:
- Fix compact+daemon interaction or error message.
- Update "bd merge" help text.
- Add "when to use daemon" section to docs.
- Add maintenance section to quickstart.

Auto-configure git merge driver during `bd init`

Enhance `bd init` to optionally set up beads-merge as git merge driver.

**Tasks**:
- Prompt user to install git merge driver
- Configure `.git/config`: `merge.beads.driver "bd merge %A %O %L %R"`
- Create/update `.gitattributes`: `.beads/beads.jsonl merge=beads`
- Add `--skip-merge-driver` flag for non-interactive use
- Update AGENTS.md onboarding section

**Files**:
- `cmd/bd/init.go`
- `.gitattributes` template


Add test coverage for internal/validation package


Remove Storage Cache from Server Struct

Eliminate cache fields and use s.storage directly


Integration test: mutation to export latency

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

Test added to daemon_test.go as TestMutationToExportLatency().

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

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

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


Add embedding generation for duplicate detection

Model: text-embedding-3-small (OpenAI) or all-MiniLM-L6-v2 (local)
Storage: SQLite vector extension or in-memory
Cost: ~/bin/bash.0002 per 100 issues

Much cheaper than LLM comparisons for large databases.

Files: internal/embeddings/ (new package)


bd validate - Comprehensive health check

Run all validation checks in one command.

Checks:
- Duplicates
- Orphaned dependencies
- Test pollution
- Git conflicts

Supports --fix-all for auto-repair.

Files: cmd/bd/validate.go (new)


Extract SQLite migrations into separate files

The file `internal/storage/sqlite/sqlite.go` is 2,136 lines and contains 11 sequential migrations alongside core storage logic. Extract migrations into a versioned system.

Current issues:
- 11 migration functions mixed with core logic
- Hard to see migration history
- Sequential migrations slow database open
- No clear migration versioning

Migration functions to extract:
- `migrateDirtyIssuesTable()`
- `migrateIssueCountersTable()`
- `migrateExternalRefColumn()`
- `migrateCompositeIndexes()`
- `migrateClosedAtConstraint()`
- `migrateCompactionColumns()`
- `migrateSnapshotsTable()`
- `migrateCompactionConfig()`
- `migrateCompactedAtCommitColumn()`
- `migrateExportHashesTable()`
- Plus 1 more (11 total)

Target structure:
```
internal/storage/sqlite/
├── sqlite.go          # Core storage (~800 lines)
├── schema.go          # Table definitions (~200 lines)
├── migrations.go      # Migration orchestration (~200 lines)
└── migrations/        # Individual migrations
    ├── 001_initial_schema.go
    ├── 002_dirty_issues.go
    ├── 003_issue_counters.go
    [... through 011_export_hashes.go]
```

Benefits:
- Clear migration history
- Each migration self-contained
- Easier to review migration changes in PRs
- Future migrations easier to add


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

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

Current coverage: 24.8% (improved from 20.2%)

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

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

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

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

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


Research hooks/skills approach for enforcing issue descriptions

## Solution: Hooks/Skills (mentioned in discussion)

Research the hooks/skills system mentioned by riordanpawley in discussion #366:
https://www.reddit.com/r/ClaudeAI/s/wrn2tjkMHX

## Investigation Tasks

1. Review the Reddit post to understand the approach
2. Determine if beads hooks can enforce validation
3. Check if Claude Code skills/hooks can intercept MCP calls
4. Assess feasibility and user burden

## Notes

From discussion #366:
> I'm using a skills/hooks system to get Claude to do that kind of thing right similar to https://www.reddit.com/r/ClaudeAI/s/wrn2tjkMHX

This might be a client-side solution rather than server-side.

## Deliverable

Document findings in issue notes, with recommendation on whether to pursue this approach.


Implement content-hash based collision resolution for deterministic convergence

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

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

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

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


Merge PR #300: gitignore upgrade feature

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

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

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

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


Daemon crash recovery: panic handler + socket cleanup

Improve daemon cleanup on unexpected exit:
1. Add top-level recover() in runDaemonLoop to capture panics
2. Write daemon-error file with stack trace on panic
3. Prefer return over os.Exit where possible (so defers run)
4. In stopDaemon forced-kill path, also remove stale socket if present

This ensures better diagnostics and cleaner state after crashes.


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


Test npm package installation locally

  - bd list --json
  - bd sync

## Test environments
- macOS (darwin-arm64 and darwin-amd64)
- Linux (ubuntu docker container for linux-amd64)
- Windows (optional, if available)

## Validation
- Binary downloads during postinstall
- All bd commands work identically to native
- No permission issues
- Proper error messages on failure


Latency test 1


Add comprehensive tests for show.go commands (show, update, edit, close)

Need to add tests for cmd/bd/show.go which contains show, update, edit, and close commands.

**Challenge**: The existing test patterns use rootCmd.SetArgs() and rootCmd.Execute(), but the global `store` variable needs to match what the commands use. Initial attempt created tests that failed with "no issue found" because the test's store instance wasn't the same as the command's store.

**Files to test**:
- show.go (contains showCmd, updateCmd, editCmd, closeCmd)

**Coverage needed**:
- show command (single issue, multiple issues, JSON output, with dependencies, with labels, with compaction)
- update command (status, priority, title, assignee, description, multiple fields, multiple issues)
- edit command (requires $EDITOR, may need mocking)
- close command (single issue, multiple issues, with reason, JSON output)

**Test approach**:
1. Study working test patterns in init_test.go, list_test.go, etc.
2. Ensure BEADS_NO_DAEMON=1 is set
3. Properly initialize database with bd init
4. Use the command's global store, not a separate instance
5. May need to reset global state between tests

**Success criteria**:
- All test functions pass
- Coverage for show.go increases significantly
- Tests follow existing patterns in cmd/bd/*_test.go


Fix unvalidated dependency parsing in create.go

**Location:** cmd/bd/create.go:278-298

**Issue:** Dependency parsing loop breaks on first 'discovered-from' type without validating dependsOnID is non-empty.

**Current Code:**
```go
if depType == types.DepDiscoveredFrom {
    discoveredFromParentID = dependsOnID  // Could be ""!
    break
}
```

**Impact:** Malformed dependency like "discovered-from:" (empty ID) will set discoveredFromParentID to empty string, causing line 303 to attempt getting issue with empty ID.

**Fix:**
```go
if depType == types.DepDiscoveredFrom && dependsOnID != "" {
    discoveredFromParentID = dependsOnID
    break
}
```


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?


npm package for bd with native binaries

Create an npm package that wraps native bd binaries for easy installation in Claude Code for Web and other Node.js environments.

## Problem
Claude Code for Web sandboxes are full Linux VMs with npm support, but cannot easily download binaries from GitHub releases due to network restrictions or tooling limitations.

## Solution
Publish bd as an npm package that:
- Downloads platform-specific native binaries during postinstall
- Provides a CLI wrapper that invokes the native binary
- Works seamlessly in Claude Code for Web SessionStart hooks
- Maintains full feature parity (uses native SQLite)

## Benefits vs WASM
- ✅ Full SQLite support (no custom VFS needed)
- ✅ All features work identically to native bd
- ✅ Better performance (native vs WASM overhead)
- ✅ ~4 hours effort vs ~2 days for WASM
- ✅ Minimal maintenance burden

## Success Criteria
- npm install @beads/bd works in Claude Code for Web
- All bd commands function identically to native binary
- SessionStart hook documented for auto-installation
- Package published to npm registry


Add MCP server functions for repair commands

Expose new repair commands via MCP server for agent access:

Functions to add:

Daemon crashes silently on RPC query after startup

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

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

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

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

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

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


Centralize error handling patterns in storage layer

80+ instances of inconsistent error handling across sqlite.go with mix of %w, %v, and no wrapping.

Location: internal/storage/sqlite/sqlite.go (throughout)

Problem:
- Some use fmt.Errorf("op failed: %w", err) - correct wrapping
- Some use fmt.Errorf("op failed: %v", err) - loses error chain
- Some return err directly - no context
- Hard to debug production issues
- Can't distinguish error types

Solution: Create internal/storage/sqlite/errors.go:
- Define sentinel errors (ErrNotFound, ErrInvalidID, etc.)
- Create wrapDBError(op string, err error) helper
- Convert sql.ErrNoRows to ErrNotFound
- Always wrap with operation context

Impact: Lost error context; inconsistent messages; hard to debug

Effort: 5-7 hours


bd init creates nested .beads directories

bd init sometimes creates .beads/.beads/ nested directories, which should never happen. This occurs fairly often and can cause confusion about which .beads directory is active. Need to add validation to detect if already inside a .beads directory and either error or use the parent .beads location.

WASM port of bd for Claude Code Web sandboxes

Enable beads to work in Claude Code Web sandboxes by compiling bd to WebAssembly.

## Problem
Claude Code Web sandboxes cannot install bd CLI due to network restrictions:
- GitHub releases return 403
- go install fails with DNS errors
- Binary cannot be downloaded

## Solution
Compile bd Go codebase to WASM, publish to npm as drop-in replacement.

## Technical Approach
- Use GOOS=js GOARCH=wasm to compile bd
- modernc.org/sqlite already supports js/wasm target
- Publish to npm as bd-wasm package
- Full feature parity with bd CLI

## Success Criteria
- bd-wasm installs via npm in web sandbox
- All core bd commands work identically
- JSONL output matches native bd
- Performance within 2x of native

WASM port abandoned - Claude Code Web has full VMs not browser restrictions. Better: npm + native binary


bd find-duplicates - AI-powered duplicate detection

Find semantically duplicate issues.

Approaches:
1. Mechanical: Exact title/description matching
2. Embeddings: Cosine similarity (cheap, scalable)
3. AI: LLM-based semantic comparison (expensive, accurate)

Uses embeddings by default for >100 issues.

Measure git operation reduction

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

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

Success Metric: ≥70% reduction in git operations


Optimize CLI test suite - eliminate redundant git init calls

Current: Each of 13 CLI tests calls git init (31s total). Solution: Use single test binary built once in init(), skip git operations where possible, or use mock filesystem.


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


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

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

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

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

## Proposed Architecture

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

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

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

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

## Implementation Phases

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

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

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

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

## Risks & Mitigations

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

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

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

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

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

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

File: pkg/agentmail/client.go

Note: Lower priority - can shell out to curl initially


Claude Code frequently creates issues with empty descriptions

## Problem

Users report that Claude Code creates beads issues with titles but no descriptions when asked to analyze code and create issues. Discussion #366 on GitHub highlights this.

## Evidence

Analysis of our own projects shows significant rates of empty descriptions:
- ~/src/beads: 110 empty / 630 total (17.5%)
- ~/wyvern: 8 empty / 119 total (6.7%)
- ~/src/vc: 3 empty / 170 total (1.8%)

Examples of real issues with no description:
- [deleted:bd-5qim]: Optimize GetReadyWork performance
- bd-ge7/vc-7kln: Improve test coverage (appears in multiple projects)
- Package-specific test coverage tasks (bd-m0w, bd-4h3, bd-t3b, bd-e92)
- Wyvern testing tasks (wy-3hx, wy-qc9, wy-66)

Many date from Nov 20-21, suggesting batch creation operations.

## Impact

- Issues lack context for future work
- Harder to prioritize without understanding scope
- Need manual follow-up to add details
- Poor workflow experience for users

Add content-addressable identity to Issue type

## Overview
Phase 1: Add content hashing to enable global identification of issues regardless of their assigned IDs.

## Current Problem
The system identifies issues only by ID (e.g., test-1, test-2). When multiple clones create the same ID with different content, there's no way to identify that these are semantically different issues without comparing all fields.

## Solution
Add a ContentHash field to the Issue type that represents the canonical content fingerprint.

## Implementation Tasks

### 1. Add ContentHash field to Issue type
File: internal/types/types.go
```go
type Issue struct {
    ID          string
    ContentHash string  // SHA256 of canonical content
    // ... existing fields
}
```

### 2. Add content hash computation method
Use existing hashIssueContent from collision.go:186 as foundation:
```go
func (i *Issue) ComputeContentHash() string {
    return hashIssueContent(i)
}
```

### 3. Compute hash at creation time
- Modify CreateIssue to compute and store ContentHash
- Modify CreateIssues (batch) to compute hashes

### 4. Compute hash at import time
- Modify ImportIssues to compute ContentHash for all incoming issues
- Store hash in database

### 5. Add database column
- Add migration to add content_hash column to issues table
- Update SELECT/INSERT statements to include content_hash
- Index on content_hash for fast lookups

### 6. Populate existing issues
- Add migration step to compute ContentHash for all existing issues
- Use hashIssueContent function

## Acceptance Criteria
- Issue type has ContentHash field
- Hash is computed automatically at creation time
- Hash is computed for imported issues
- Database stores content_hash column
- All existing issues have non-empty ContentHash
- Hash is deterministic (same content → same hash)
- Hash excludes ID, timestamps (only semantic content)

## Files to Modify
- internal/types/types.go
- internal/storage/sqlite/sqlite.go (schema, CreateIssue, CreateIssues)
- internal/storage/sqlite/migrations.go (new migration)
- internal/importer/importer.go (compute hash during import)
- cmd/bd/create.go (compute hash at creation)

## Testing
- Unit test: same content produces same hash
- Unit test: different content produces different hash
- Unit test: hash excludes ID and timestamps
- Integration test: hash persists in database
- Migration test: existing issues get hashes populated


Test label update feature


Update JSONL format to use hash IDs

Update JSONL import/export to use hash IDs, store aliases separately.

## Current JSONL Format
```jsonl
{"id":"bd-1c63eb84","title":"Fix bug","status":"open",...}
{"id":"bd-9063acda","title":"Add test","status":"open",...}
```

## New JSONL Format (Option A: Include Alias)
```jsonl
{"id":"bd-af78e9a2","alias":1,"title":"Fix bug","status":"open",...}
{"id":"bd-e5f6a7b8","alias":2,"title":"Add test","status":"open",...}
```

## New JSONL Format (Option B: Hash ID Only)
```jsonl
{"id":"bd-af78e9a2","title":"Fix bug","status":"open",...}
{"id":"bd-e5f6a7b8","title":"Add test","status":"open",...}
```

Store aliases in separate .beads/aliases.jsonl (local only, git-ignored):
```jsonl
{"hash":"bd-af78e9a2","alias":1}
{"hash":"bd-e5f6a7b8","alias":2}
```

**Recommendation**: Option B (hash only in main JSONL)
- Cleaner git diffs (no alias conflicts)
- Aliases are workspace-local preference
- Main JSONL is canonical, portable

## Export Changes
File: cmd/bd/export.go
```go
// Export issues with hash IDs
for _, issue := range issues {
    json := marshalIssue(issue)  // Uses issue.ID (hash)
    // Don't include alias in JSONL
}

// Separately export aliases to .beads/aliases.jsonl
exportAliases(issues)
```

## Import Changes
File: cmd/bd/import.go, internal/importer/importer.go
```go
// Import issues by hash ID
issue := unmarshalIssue(line)
// Assign new alias on import (don't use incoming alias)
issue.Alias = getNextAlias()

// No collision detection needed! Hash IDs are globally unique
```

## Dependency Reference Format
No change needed - already uses issue IDs:
```json
{"depends_on_id":"bd-af78e9a2","type":"blocks"}
```

## Files to Modify
- cmd/bd/export.go (use hash IDs)
- cmd/bd/import.go (import hash IDs, assign aliases)
- internal/importer/importer.go (remove collision detection!)
- .gitignore (add .beads/aliases.jsonl)

## Testing
- Test export produces hash IDs
- Test import assigns new aliases
- Test dependencies preserved with hash IDs
- Test no collision detection triggered

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._


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


bd doctor doesn't detect version mismatches or stale daemons


Update docs with multi-repo patterns

Update AGENTS.md, README.md, QUICKSTART.md with multi-repo patterns. Document: config options, routing behavior, backward compatibility, troubleshooting, best practices.


Refactor create_test.go to use shared DB setup

Convert TestCreate_* functions to use test suites with shared database setup.

Example transformation:
- Before: 10 separate tests, each with newTestStore()
- After: 1 TestCreate() with 10 t.Run() subtests sharing one DB

Estimated speedup: 10x faster (1 DB setup instead of 10)


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


Update AGENTS.md with event-driven mode

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


Update LINTING.md with current baseline

After cleanup, document the remaining acceptable baseline in LINTING.md so we can track regression.


Extract duplicated validation logic from CLI commands

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

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

Solution: Extract to shared packages:
- internal/validation/bead.go - Centralized validation
- internal/utils/time.go - Consolidate time parsing (already exists)
- cmd/bd/flags.go - Shared flag registration

Impact: Changes require touching 2+ files; high risk of inconsistency; steep learning curve

Effort: 4-6 hours


Optimize Memory backend GetIssueByExternalRef with index

Currently GetIssueByExternalRef in Memory storage uses O(n) linear search through all issues.

Current code (memory.go:282-308):
for _, issue := range m.issues {
    if issue.ExternalRef != nil && *issue.ExternalRef == externalRef {
        return &issueCopy, nil
    }
}

Proposed optimization:
- Add externalRefToID map[string]string to MemoryStorage
- Maintain it in CreateIssue, UpdateIssue, DeleteIssue
- Achieve O(1) lookup like SQLite's index

Impact: Low (--no-db mode typically has smaller datasets)
Related: bd-1022


Split monolithic sqlite.go into focused files

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

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

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

Effort: 6-8 hours


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).


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


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.

Deletions not propagated across multi-workspace sync

## Problem

When working with multiple beads workspaces (clones) sharing the same git remote, deleted issues keep coming back.

## Reproduction

1. Clone A deletes issue `bd-xyz` via `bd delete bd-xyz --force`
2. Clone A daemon syncs and pushes to GitHub
3. Clone B still has `bd-xyz` in its database
4. Clone B daemon exports and pushes its JSONL
5. Clone A pulls and imports → `bd-xyz` comes back!

## Root Cause

**No deletion tracking mechanism.** The system has no way to distinguish between:
- "Issue doesn't exist in JSONL because it was deleted"
- "Issue doesn't exist in JSONL because the export is stale"

Import treats missing issues as "not in this export" rather than "explicitly deleted."

## Solution Options

1. **Tombstone records** - Keep deleted issues in JSONL with `"status":"deleted"` or `"deleted_at"` field
2. **Deletion log** - Separate `.beads/deletions.jsonl` file tracking all deleted IDs
3. **Three-way merge** - Import compares: DB state, old JSONL, new JSONL
4. **Manual conflict resolution** - Detect resurrection and prompt user

## Related

- Similar to resurrection logic for orphaned children (bd-cc4f)
- beads-merge tool handles this better with 3-way merge


Create startup hook snippet for upgrade detection

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

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

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

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

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


Update daemon commit logic for separate branch

Modify daemon to use worktree for commits when sync.branch configured.

Tasks:
- Update internal/daemon/server_export_import_auto.go
- Detect sync.branch configuration
- Ensure worktree exists before commit
- Sync JSONL to worktree
- Commit in worktree context
- Push to configured branch
- Fallback to current behavior if sync.branch not set
- Handle git errors (network, permissions, conflicts)

Estimated effort: 3-4 days


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).


BG's issue to reopen


Fix race condition in client socket cleanup (client.go)

**Location:** internal/rpc/client.go:44-76

**Issue:** TryConnectWithTimeout() has race window between socket existence check and lock file check.

**Problematic Sequence:**
```go
socketExists := endpointExists(socketPath)  // line 56
if !socketExists {
    beadsDir := filepath.Dir(socketPath)
    running, _ := lockfile.TryDaemonLock(beadsDir)  // line 61
    // RACE: socket could've been deleted between lines 56 and 61
}
```

**Impact:** Could incorrectly report daemon as running when it crashed. Socket gets deleted during cleanup but lock file still held temporarily.

**Fix:** Combine checks atomically or use transactional approach with proper locking.


Document bd-wasm installation and usage

Create documentation for bd-wasm:
- Update README with npm installation instructions
- Add troubleshooting section for WASM-specific issues
- Document known limitations vs native bd
- Add examples for Claude Code Web sandbox usage
- Update INSTALLING.md with bd-wasm option


Measure notification latency vs git sync

Benchmark end-to-end latency for status updates to propagate between agents using both methods.

Acceptance Criteria:
- Measure git sync latency (commit → push → pull → import)
- Measure Agent Mail latency (send_message → fetch_inbox)
- Document latency distribution (p50, p95, p99)
- Verify <100ms claim for Agent Mail
- Compare against 1-5s baseline for git

Success Metric: Agent Mail latency < 100ms, git sync latency > 1000ms

Latency benchmark completed. Results documented in latency_results.md:
- Git sync: 2000-5000ms (full cycle with network)
- Agent Mail: <100ms (HTTP API round-trip)
- Confirms 20-50x latency reduction claim


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

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


Workaround for FastMCP outputSchema bug in Claude Code

The beads MCP server (v0.23.1) successfully connects to Claude Code, but all tools fail to load with a schema validation error due to a bug in FastMCP 2.13.1.

Error: "Invalid literal value, expected \"object\"" in outputSchema.

Root Cause: FastMCP generates outputSchema with $ref at root level without "type": "object" for self-referential models (Issue).

Workaround: Use slash commands (/beads:ready) or wait for FastMCP fix.

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


Daemon crashes silently when multiple .db files exist in .beads/

When daemon detects multiple .db files (after filtering out .backup and vc.db files), it writes error details to .beads/daemon-error file before exiting.

The error file is checked when:
1. Daemon discovery fails to connect (internal/daemon/discovery.go)
2. Auto-start fails to yield a running daemon (cmd/bd/main.go)
3. Daemon list shows 'daemon not responding' error

This makes the error immediately visible to users without requiring them to check daemon logs.

File created:  cmd/bd/daemon.go (writes daemon-error on multiple .db detection)
Files modified:
- internal/daemon/discovery.go (reads daemon-error and surfaces in DaemonInfo.Error)
- cmd/bd/main.go (displays daemon-error when auto-start fails)

Testing: Create multiple .db files in .beads/, start daemon, verify error file created and shown in bd daemons list

Root cause: Daemon exits with os.Exit(1) when multiple .db files detected (daemon.go:1381), but error only goes to daemon log file. User sees 'daemon not responding' without knowing why.

Current detection:
- daemon.go filters out .backup and vc.db files
- bd doctor detects multiple databases
- Error message tells user to run 'bd init' or manually remove

Problem: Error is not user-visible unless they check daemon logs.

Proposed fix options:
1. Surface the error in 'bd info' and 'bd daemons list' output
2. Add a hint in error messages to run 'bd doctor' when daemon fails
3. Make daemon write error to a .beads/daemon-error file that gets checked
4. Improve 'bd doctor' to run automatically when daemon is unhealthy


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-cbed9619.2 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


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.


Separate process/lock/PID concerns into process.go

Create internal/daemonrunner/process.go with: acquireDaemonLock, PID file read/write, stopDaemon, isDaemonRunning, getPIDFilePath, socket path helpers, version check.


Add upgrade notification system to bd ready/list


Migration tool for existing users

Ensure smooth migration for existing users to separate branch workflow.

Tasks:
- Add bd migrate --separate-branch command
- Detect existing repos, migrate cleanly
- Preserve git history
- Add rollback mechanism
- Test migration on beads' own repo (dogfooding)
- Communication plan (GitHub discussion, docs)
- Version compatibility checks

Estimated effort: 2-3 days


Extract hash ID generation functions to hash_ids.go

Move generateHashID, getNextChildNumber, GetNextChildID to hash_ids.go


Document blocked_issues_cache architecture and behavior

Add comprehensive documentation about the blocked_issues_cache optimization to help future maintainers understand the design.

## What to document

1. **Architecture overview**
   - Why cache exists (performance: 752ms -> 29ms)
   - When cache is used (GetReadyWork queries)
   - How cache is maintained (invalidation triggers)

2. **Cache invalidation rules**
   - Invalidated on: dependency add/remove (blocks/parent-child only)
   - Invalidated on: any status change
   - Invalidated on: issue close
   - NOT invalidated on: related/discovered-from dependencies

3. **Transaction safety**
   - All invalidations happen within transactions
   - Cache can use tx or direct db connection
   - Rebuild is atomic (DELETE + INSERT in same tx)

4. **Performance characteristics**
   - Full rebuild on every invalidation
   - Rebuild is fast (<50ms on 10K database)
   - Write complexity traded for read speed
   - Dependency changes are rare vs reads

5. **Edge cases**
   - Parent-child transitive blocking
   - Closed issues don't block
   - Foreign key CASCADE handles deletions

## Where to document

Add to these locations:

1. **blocked_cache.go** - Add detailed package comment:
```go
// Package blocked_cache implements the blocked_issues_cache optimization.
//
// Performance: GetReadyWork originally used recursive CTE (752ms on 10K db).
// With cache: Simple NOT EXISTS query (29ms on 10K db).
//
// Cache Maintenance:
// - Rebuild triggered on dependency changes (blocks/parent-child only)
// - Rebuild triggered on status changes
// - Full rebuild (DELETE + INSERT) is fast enough for all cases
// ...
```

2. **ARCHITECTURE.md** or **PERFORMANCE.md** (new file) - High-level overview

3. **ready.go** - Update comment at line 84-85 with more detail

Add 'bd message send' command for Agent Mail messaging

Agent Mail server supports messaging between agents, but bd CLI only uses it for file reservations. Add commands for inter-agent messaging.

## Background
- Agent Mail server running at http://127.0.0.1:8765
- 12 workspaces configured across 3 channels (beads.dev, vc.dev, wyvern.dev)
- Current integration: file reservations only
- Gap: no way to send messages from bd CLI

## Proposed Commands

```bash
# Send message to another agent
bd message send <to-agent> <message> [options]
  --subject <subject>
  --thread-id <thread-id>     # Optional - group related messages
  --project-id <project>      # Defaults to BEADS_PROJECT_ID

# List inbox messages
bd message inbox [options]
  --limit <N>
  --unread-only

# Read specific message
bd message read <message-id>

# Mark message as acknowledged
bd message ack <message-id>
```

## Example Usage

```bash
# Send message to agent in same channel
bd message send cino-beads-stevey-macbook "Working on bd-z0yn, need your review" \
  --subject "Review request" \
  --thread-id bd-z0yn

# Check inbox
bd message inbox --unread-only

# Read and acknowledge
bd message read msg-abc123
bd message ack msg-abc123
```

## Design Notes
- Use same env vars (BEADS_AGENT_MAIL_URL, BEADS_AGENT_NAME, BEADS_PROJECT_ID)
- Graceful degradation if Agent Mail unavailable
- JSON output support for all commands
- Consider integrating with bd update/close (auto-notify on status changes)

## References
- Agent Mail README: ~/src/mcp_agent_mail/README.md
- Beads integration docs: docs/AGENT_MAIL.md

## Implementation Summary

Added four new commands to bd CLI for Agent Mail messaging:

1. `bd message send <to-agent> <message>` - Send messages to other agents
   - Flags: --subject, --thread-id, --importance, --ack-required
   - Supports markdown content
   - Thread conversations by issue ID

2. `bd message inbox` - List inbox messages
   - Flags: --limit, --unread-only, --urgent-only, --json
   - Shows subject, sender, age, importance
   - Highlights unread and ACK-required messages

3. `bd message read <message-id>` - Read and mark message as read
   - Automatically marks message as read
   - Shows message content

4. `bd message ack <message-id>` - Acknowledge a message
   - Marks message as acknowledged
   - Also marks as read if not already

## Implementation Details

- Uses JSON-RPC over HTTP to communicate with Agent Mail server
- Configuration via environment variables (BEADS_AGENT_MAIL_URL, BEADS_AGENT_NAME, BEADS_PROJECT_ID)
- Graceful error messages when Agent Mail not configured
- Full JSON output support for programmatic use
- Follows same patterns as existing bd commands

## Documentation

Updated:
- docs/AGENT_MAIL.md - Added "Messaging Commands" section with examples and best practices
- README.md - Added "Messaging (Agent Mail)" section in Usage

## Testing

- Compiles successfully
- Help output works correctly
- Ready for integration testing with Agent Mail server


~/src/beads daemon has 'sql: database is closed' errors - zombie daemon


Add explicit cache validation tests for blocked_issues_cache

The blocked_issues_cache optimization works correctly but lacks explicit tests that verify cache invalidation behavior.

## What to test

1. **Cache invalidation on dependency add**
   - Add a blocking dependency
   - Verify blocked issue appears in cache

2. **Cache invalidation on dependency remove**
   - Remove a blocking dependency
   - Verify blocked issue removed from cache

3. **Cache invalidation on status change**
   - Close a blocker issue
   - Verify dependent issue removed from cache
   - Reopen blocker
   - Verify dependent issue added back to cache

4. **Cache consistency across operations**
   - Multiple dependency changes in sequence
   - Verify cache stays consistent with actual blocking state

5. **Parent-child transitive blocking**
   - Create epic with child tasks
   - Add blocking dependency to epic
   - Verify all children appear in cache

## Implementation

Add tests to internal/storage/sqlite/blocked_cache_test.go (new file) with direct cache queries:

```go
func TestBlockedCacheInvalidation(t *testing.T) {
    // Verify cache updates correctly on dependency changes
}

func TestBlockedCacheConsistency(t *testing.T) {
    // Verify cache matches actual blocking state
}
```

## Why this matters

- Current tests verify behavior but not implementation
- Explicit cache tests catch cache-specific bugs
- Makes cache correctness visible in test output
- Easier debugging if cache gets out of sync

Issue to reopen with reason


Bug P0


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


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.


Change default JSONL filename from beads.jsonl back to issues.jsonl throughout codebase


bd doctor --json flag not working

The --json flag on bd doctor command doesn't produce JSON output. It continues to show human-readable output instead. The flag is registered locally on doctorCmd but the code uses the global jsonOutput variable set by PersistentPreRun. Need to investigate why the flag isn't being honored.


Extract computeJSONLHash helper to eliminate code duplication

SHA256 hash computation is duplicated in 3 places:
- cmd/bd/integrity.go:50-52
- cmd/bd/sync.go:611-613
- cmd/bd/import.go:318-319

Extract to shared helper function computeJSONLHash(jsonlPath string) (string, error) that includes proper #nosec comment and error handling.


Fix `bd sync` failure due to daemon auto-export timestamp skew

`bd sync` fails with false-positive "JSONL is newer than database" after daemon auto-export.
Root Cause: Daemon exports local changes to JSONL, updating its timestamp. `bd sync` sees JSONL.mtime > DB.mtime and assumes external changes, blocking export.
Proposed Fixes:
1. `bd sync` auto-imports if timestamp matches but content differs (or just auto-imports).
2. Content-based comparison instead of timestamp only.


CLI accepts both hash IDs and aliases

Update all CLI commands to accept both hash IDs (bd-af78e9a2) and aliases (#42, or just 42).

## Parsing Logic
```go
// internal/utils/id_parser.go
func ParseIssueID(input string) (issueID string, err error) {
    // Hash ID: bd-af78e9a2
    if strings.HasPrefix(input, "bd-") {
        return input, nil
    }

    // Alias: #42 or 42
    aliasStr := strings.TrimPrefix(input, "#")
    alias, err := strconv.Atoi(aliasStr)
    if err != nil {
        return "", fmt.Errorf("invalid issue ID: %s", input)
    }

    // Resolve alias to hash ID
    return storage.GetIssueIDByAlias(alias)
}
```

## Commands to Update
All commands that accept issue IDs:

### 1. bd show
```bash
bd show bd-af78e9a2        # Hash ID
bd show #42                # Alias
bd show 42                 # Alias (shorthand)
bd show bd-af78e9a2 #42    # Mixed (multiple IDs)
```

### 2. bd update
```bash
bd update #42 --status in_progress
bd update bd-af78e9a2 --priority 1
```

### 3. bd close
```bash
bd close #42 --reason "Done"
```

### 4. bd dep add/tree
```bash
bd dep add #42 #1 --type blocks
bd dep tree bd-af78e9a2
```

### 5. bd label add/remove
```bash
bd label add #42 critical
```

### 6. bd merge
```bash
bd merge #42 #43 --into #41
```

## Display Format
Default to showing aliases in output:
```bash
$ bd list
#1   Fix authentication bug          P1  open
#2   Add logging to daemon           P2  open
#42  Investigate jujutsu integration P3  open
```

With `--format=hash` flag:
```bash
$ bd list --format=hash
bd-af78e9a2  Fix authentication bug          P1  open
bd-e5f6a7b8  Add logging to daemon           P2  open
bd-1a2b3c4d  Investigate jujutsu integration P3  open
```

## Files to Modify
- internal/utils/id_parser.go (new)
- cmd/bd/show.go
- cmd/bd/update.go
- cmd/bd/close.go
- cmd/bd/reopen.go
- cmd/bd/dep.go
- cmd/bd/label.go
- cmd/bd/merge.go
- cmd/bd/list.go (add --format flag)

## Testing
- Test hash ID parsing
- Test alias parsing (#42, 42)
- Test mixed IDs in single command
- Test error on invalid ID
- Test alias resolution failure


Delete collision resolution code

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

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

## Code to Remove from Existing Files

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

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

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

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

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

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

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

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

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

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


Test exclusive file reservations with two agents

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

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

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


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

Test integration issue

This is a real integration test


Code review bd-loka implementation


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.


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.


Add `bd merge` command wrapping 3-way merge logic

Implement CLI command to invoke beads-merge functionality.

**Interface**:
```bash
bd merge <output> <base> <left> <right>
bd merge --debug <output> <base> <left> <right>
```

**Behavior**:
- Exit code 0 on clean merge
- Exit code 1 if conflicts (write conflict markers)
- Support --debug flag for verbose output
- Match beads-merge's existing behavior

**File**: `cmd/bd/merge.go`


bd config set succeeds but doesn't persist to config.toml

Commands like `bd config set daemon.auto_push true` return "Set daemon.auto_push = true" but the config file is never created and `bd info --json | jq '.config'` returns null.

**Steps to reproduce:**
1. Run `bd config set daemon.auto_push true`
2. See success message: "Set daemon.auto_push = true"
3. Check `cat .beads/config.toml` → file doesn't exist
4. Check `bd info --json | jq '.config'` → returns null

**Expected:**
- .beads/config.toml should be created with the setting
- bd info should show the config value

**Impact:**
Users can't enable auto-push/auto-commit via CLI as documented in AGENTS.md


Document protected branch workflow

Create comprehensive documentation for protected branch workflow.

Tasks:
- Add "Protected Branch Workflow" section to AGENTS.md
- Create docs/PROTECTED_BRANCHES.md guide
- Update README.md quick start
- Add examples to examples/protected-branch/
- Update bd init --help documentation
- Add troubleshooting guide
- Add migration guide for existing users
- Record demo video (optional)

Estimated effort: 2-3 days

Completed protected branch workflow documentation. Created comprehensive guide (docs/PROTECTED_BRANCHES.md), updated AGENTS.md with workflow section, added feature to README.md, and created working example (examples/protected-branch/). All commands verified working (bd init --branch, bd sync --status, bd sync --merge, bd config get/set sync.branch).


Create queries.go with core issue CRUD methods


Fix linting error in migrate.go

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

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


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)


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.


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)).


Fix multi-round convergence for N-way collisions

## Problem

N-way collision resolution is working (IDs get remapped correctly), but clones don't fully converge after a single final pull. Each clone is missing some issues that other clones have.

From TestFiveCloneCollision results:
- Clone A has: A, B
- Clone B has: A, B
- Clone C has: A, B, C
- Clone D has: A, B, C, D
- Clone E has: A, B, C, E

**Expected**: All clones should have A, B, C, D, E after final pull.

## Root Cause

The current sync workflow does:
1. Each clone syncs in order (resolving collisions locally)
2. Final pull to get all changes

But the final pull itself may need import with collision resolution, which creates new commits. These new commits aren't propagated to other clones, so they remain incomplete.

## Proposed Solution

**Option 1: Multi-round final sync**
- After final pull, do additional sync rounds until all clones converge
- Check convergence by comparing issue counts or content hashes
- Maximum N rounds for N clones

**Option 2: Iterative pull-import-push**
- Each clone: pull → import with --resolve-collisions → push
- Repeat until no new changes
- Guaranteed convergence but may create commit spam

**Option 3: Fix auto-import to be truly idempotent**
- Ensure importing same JSONL multiple times produces no new commits
- May require smarter content-based deduplication

## Acceptance Criteria

- TestFiveCloneCollision passes without t.Skip
- All N clones have all N issues after convergence
- Convergence happens in bounded rounds (≤ N)
- No data loss or duplication
- Works for arbitrary N (tested with 5, 10 clones)

## Impact

This is the final blocker for bd-cbed9619 epic completion.


Extract batch operations to batch_ops.go

Move validateBatchIssues, generateBatchIDs, bulkInsertIssues, bulkRecordEvents, bulkMarkDirty, CreateIssues to batch_ops.go


Delete server_cache_storage.go

Remove the entire cache implementation file (~286 lines)


Split internal/rpc/server.go into focused modules

The file `internal/rpc/server.go` is 2,273 lines with 50+ methods, making it difficult to navigate and prone to merge conflicts. Split into 8 focused files with clear responsibilities.

Current structure: Single 2,273-line file with:
- Connection handling
- Request routing
- All 40+ RPC method implementations
- Storage caching
- Health checks & metrics
- Cleanup loops

Target structure:
```
internal/rpc/
├── server.go          # Core server, connection handling (~300 lines)
├── methods_issue.go   # Issue operations (~400 lines)
├── methods_deps.go    # Dependency operations (~200 lines)
├── methods_labels.go  # Label operations (~150 lines)
├── methods_ready.go   # Ready work queries (~150 lines)
├── methods_compact.go # Compaction operations (~200 lines)
├── methods_comments.go # Comment operations (~150 lines)
├── storage_cache.go   # Storage caching logic (~300 lines)
└── health.go          # Health & metrics (~200 lines)
```

Migration strategy:
1. Create new files with appropriate methods
2. Keep `server.go` as main file with core server logic
3. Test incrementally after each file split
4. Final verification with full test suite


bd sync should auto-resolve JSONL merge conflicts by exporting from DB

## Problem

When bd sync encounters a merge conflict in beads.jsonl during git pull/rebase, it fails and tells the user to manually resolve it. The typical resolution is:

```bash
bd export -o .beads/beads.jsonl
git add .beads/beads.jsonl
git rebase --continue
bd sync  # try again
```

This is tedious and error-prone. The user shouldn't need to know these git internals.

## Root Cause

bd sync doesn't handle the case where:
1. Export succeeds → commit created
2. Pull/rebase starts
3. JSONL has merge conflict
4. Process aborts, leaving user in broken rebase state

## Proposed Solution

When bd sync detects a merge conflict in beads.jsonl during pull/rebase:

1. **Auto-detect conflict**: Check if git status shows 'both modified' on beads.jsonl
2. **Auto-resolve**: Run `bd export -o .beads/beads.jsonl` to overwrite with DB state
3. **Mark resolved**: Run `git add .beads/beads.jsonl`
4. **Continue**: Run `git rebase --continue` automatically
5. **Complete sync**: Continue with normal push flow

## Implementation

Location: `cmd/bd/sync.go`

After git pull fails:
```go
if err := runGitPull(); err != nil {
    // Check if it's a rebase conflict
    if isInRebase() && hasJSONLConflict() {
        log.Info("→ Auto-resolving JSONL merge conflict...")

        // Export clean JSONL from DB
        if err := exportJSONL(); err != nil {
            return fmt.Errorf("failed to export for conflict resolution: %w", err)
        }

        // Mark as resolved
        if err := runGitAdd(".beads/beads.jsonl"); err != nil {
            return fmt.Errorf("failed to mark conflict resolved: %w", err)
        }

        // Continue rebase
        if err := runGitRebaseContinue(); err != nil {
            return fmt.Errorf("failed to continue rebase: %w", err)
        }

        log.Info("✓ Auto-resolved JSONL conflict")
    } else {
        return err  // Other error, fail normally
    }
}
```

Helper functions needed:
- `isInRebase() bool` - check if .git/rebase-merge or .git/rebase-apply exists
- `hasJSONLConflict() bool` - check git status for 'both modified' on beads.jsonl
- `runGitRebaseContinue() error` - run git rebase --continue

## Benefits

- Seamless multi-user workflow
- No manual git intervention needed
- Database is always source of truth for local changes
- Matches user mental model: 'bd sync should just work'

## Edge Cases

1. **Other files in conflict**: Only auto-resolve if ONLY beads.jsonl is conflicted
2. **Export fails**: Fall back to manual resolution instructions
3. **Multiple rebases**: Handle case where there are multiple commits being rebased
4. **Nested conflicts**: If rebase --continue hits another conflict, handle it

## Testing

1. Two clones, both create issues
2. Clone A syncs successfully
3. Clone B syncs → should auto-resolve and complete
4. Verify both clones have all issues
5. Verify no merge conflict markers in JSONL

## User Experience

Before:
```
$ bd sync
Error: merge conflict in beads.jsonl
[manual steps required]
```

After:
```
$ bd sync
→ Pulling from remote...
→ Auto-resolving JSONL merge conflict...
✓ Auto-resolved JSONL conflict
→ Pushing to remote...
✓ Sync complete
```

## Related Issues

This is the most common friction point in multi-user beads workflows.


Add migration guide for library consumers

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

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

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

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

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


Add internal/ai package for LLM integration

Files: internal/ai/client.go (new)


Add migration registry and simplify New()

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


Add transaction boundaries for export metadata updates

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

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

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

## Options

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

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

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

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

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

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

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


Create shared insert/event/dirty helpers

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