Introduce slog for structured daemon logging.

## Current State
Daemon uses fmt.Fprintf for logging:
```go
fmt.Fprintf(os.Stderr, "Warning: failed to detect user role: %v\n", err)
fmt.Fprintf(logFile, "[%s] %s\n", time.Now().Format(time.RFC3339), msg)
```

This produces unstructured, hard-to-parse logs.

## Target State
Use Go 1.21+ slog for structured logging:
```go
slog.Warn("failed to detect user role", "error", err)
slog.Info("sync completed", "created", 5, "updated", 3, "duration_ms", 150)
```

## Implementation

### 1. Create logger setup (internal/daemon/logger.go)

```go
package daemon

import (
    "io"
    "log/slog"
    "os"
)

// SetupLogger configures the daemon logger.
// Returns a cleanup function to close the log file.
func SetupLogger(logPath string, jsonFormat bool, level slog.Level) (func(), error) {
    var w io.Writer = os.Stderr
    var cleanup func()

    if logPath \!= "" {
        f, err := os.OpenFile(logPath, os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0600)
        if err \!= nil {
            return nil, err
        }
        w = io.MultiWriter(os.Stderr, f)
        cleanup = func() { f.Close() }
    }

    var handler slog.Handler
    opts := &slog.HandlerOptions{Level: level}

    if jsonFormat {
        handler = slog.NewJSONHandler(w, opts)
    } else {
        handler = slog.NewTextHandler(w, opts)
    }

    slog.SetDefault(slog.New(handler))

    return cleanup, nil
}
```

### 2. Add log level flag

In cmd/bd/daemon.go:
```go
daemonCmd.Flags().String("log-level", "info", "Log level (debug, info, warn, error)")
daemonCmd.Flags().Bool("log-json", false, "Output logs in JSON format")
```

### 3. Replace fmt.Fprintf with slog calls

**Pattern 1: Simple messages**
```go
// Before
fmt.Fprintf(os.Stderr, "Starting daemon on %s\n", socketPath)

// After
slog.Info("starting daemon", "socket", socketPath)
```

**Pattern 2: Errors**
```go
// Before
fmt.Fprintf(os.Stderr, "Error: failed to connect: %v\n", err)

// After
slog.Error("failed to connect", "error", err)
```

**Pattern 3: Debug info**
```go
// Before
if debug {
    fmt.Fprintf(os.Stderr, "Received request: %s\n", method)
}

// After
slog.Debug("received request", "method", method)
```

**Pattern 4: Structured data**
```go
// Before
fmt.Fprintf(logFile, "Import: %d created, %d updated\n", created, updated)

// After
slog.Info("import completed",
    "created", created,
    "updated", updated,
    "unchanged", unchanged,
    "duration_ms", duration.Milliseconds())
```

### 4. Files to Update

| File | Changes |
|------|---------|
| cmd/bd/daemon.go | Add log flags, call SetupLogger |
| internal/daemon/server.go | Replace fmt with slog |
| internal/daemon/rpc_handler.go | Replace fmt with slog |
| internal/daemon/sync.go | Replace fmt with slog |
| internal/daemon/autoflush.go | Replace fmt with slog |
| internal/daemon/logger.go | New file |

### 5. Log output examples

**Text format (default):**
```
time=2025-12-23T12:30:00Z level=INFO msg="daemon started" socket=/tmp/bd.sock pid=12345
time=2025-12-23T12:30:01Z level=INFO msg="import completed" created=5 updated=3 duration_ms=150
time=2025-12-23T12:30:05Z level=WARN msg="sync branch diverged" local_ahead=2 remote_ahead=1
```

**JSON format (--log-json):**
```json
{"time":"2025-12-23T12:30:00Z","level":"INFO","msg":"daemon started","socket":"/tmp/bd.sock","pid":12345}
{"time":"2025-12-23T12:30:01Z","level":"INFO","msg":"import completed","created":5,"updated":3,"duration_ms":150}
```

## Migration Strategy

1. **Add logger.go** with SetupLogger
2. **Update daemon startup** to initialize slog
3. **Convert one file at a time** (start with server.go)
4. **Test after each file**
5. **Remove old logging code** once all converted

## Testing

```bash
# Start daemon with debug logging
bd daemon start --log-level debug

# Check logs
bd daemons logs . | head -20

# Test JSON output
bd daemon start --log-json --log-level debug
bd daemons logs . | jq .
```

## Success Criteria
- All daemon logging uses slog
- --log-level controls verbosity
- --log-json produces machine-parseable output
- Log entries have consistent structure
- No fmt.Fprintf to stderr in daemon code

Implemented slog for structured daemon logging with --log-level and --log-json flags


Implement bd gate create/show/list/close/wait commands

Implement the gate CLI commands.

## Commands
```bash
# Create gate (returns gate ID)
bd gate create --await <type>:<id> --timeout <duration> --notify <addr>

# Check gate status
bd gate show <id>

# List open gates
bd gate list

# Close gate (usually done by Deacon)
bd gate close <id> --reason "completed"

# Add waiter to existing gate
bd gate wait <id> --notify <addr>
```

## Implementation
- Add cmd/bd/gate.go with subcommands
- Gate create creates wisp issue of type gate
- Gate list filters for open gates
- Gate wait adds to waiters[] array
- All support --json output

Implemented bd gate commands: create, show, list, close, wait. All support --json output and work with wisp/gate fields.

Migration invariants should exclude external dependencies from orphan check

## Summary

The `checkForeignKeys` function in `migration_invariants.go` flags external dependencies as orphaned because they dont exist in the local issues table.

## Location

`internal/storage/sqlite/migration_invariants.go` around line 150-162

## Current Code (buggy)

```go
// Check for orphaned dependencies
var orphanCount int
err = db.QueryRowContext(ctx, \`
    SELECT COUNT(*)
    FROM dependencies d
    WHERE NOT EXISTS (SELECT 1 FROM issues WHERE id = d.depends_on_id)
\`).Scan(&orphanCount)
```

## Fix

Exclude external references (format: `external:<project>:<capability>`):

```go
// Check for orphaned dependencies (excluding external refs)
var orphanCount int
err = db.QueryRowContext(ctx, \`
    SELECT COUNT(*)
    FROM dependencies d
    WHERE NOT EXISTS (SELECT 1 FROM issues WHERE id = d.depends_on_id)
      AND d.depends_on_id NOT LIKE 'external:%'
\`).Scan(&orphanCount)
```

## Reproduction

```bash
# Add external dependency
bd dep add bd-xxx external:other-project:some-capability

# Try to sync - fails
bd sync
# Error: found 1 orphaned dependencies
```

## Files to Modify

1. **internal/storage/sqlite/migration_invariants.go** - Add WHERE clause

## Testing

```bash
# Create issue with external dep
bd create "Test external deps" -t task
bd dep add bd-xxx external:beads:release-workflow

# Sync should succeed
bd sync

# Verify dep exists
bd show bd-xxx --json | jq .dependencies
```

## Success Criteria
- External dependencies dont trigger orphan check
- `bd sync` succeeds with external deps
- Regular orphan detection still works for internal deps

Fixed in commit 90196eca - added NOT LIKE 'external:%' exclusion


Async Gates for Agent Coordination

Agents need an async primitive for waiting on external events (CI completion, API responses, human approval). Gates are wisp issues that block until external conditions are met, managed by the Deacon.

## Core Concepts

**Gate** = wisp issue that blocks until external condition is met
- Type: gate
- Phase: wisp (never synced, ephemeral)
- Assignee: deacon/ (Deacon monitors it)
- Fields: await_type, await_id, timeout, waiters[]

**Await Types:**
- gh:run:<id> - GitHub Actions run completion
- gh:pr:<id> - PR merged/closed
- timer:<duration> - Simple delay
- human:<prompt> - Human approval required
- mail:<pattern> - Wait for mail matching pattern

## Open Questions
- Should gates live in wisp storage or main storage with wisp flag?
- Do we need a gate catalog (like molecule catalog)?
- Should waits-for dep type work with gates?

Core beads implementation complete (types, migration, CLI). Remaining Deacon integration work moved to gastown (gt-dh65, gt-ng6g, gt-fqcz, gt-gswn).


Design contributor namespace isolation for beads pollution prevention

## Problem

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

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

## Possible Solutions to Explore

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

## Design Considerations

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

## Expansion Needed

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

Rename 'template instantiate' to 'mol bond'

Rename the template instantiation command to match molecule metaphor.

Current: bd template instantiate <id> --var key=value
Target:  bd mol bond <id> --var key=value

Changes needed:
- Add 'mol' command group (or extend existing)
- Add 'bond' subcommand that wraps template instantiate logic
- Keep 'template instantiate' as deprecated alias for backward compat
- Update help text and docs to use molecule terminology

The 'bond' verb captures:
1. Chemistry metaphor (molecules bond to form structures)
2. Dependency linking (child issues bonded in a DAG)
3. Short and active

Implemented mol command: catalog, show, bond

Phase 2.4: Git merge driver optimization for TOON format

Optimize git 3-way merge for TOON line-oriented format.

## Overview
TOON is line-oriented (unlike binary formats), enabling smarter git merge strategies. Implement custom merge driver to handle TOON-specific merge patterns.

## Required Work

### 2.4.1 TOON Merge Driver
- [ ] Create .git/info/attributes entry for *.toon files
- [ ] Implement custom merge driver script/command
- [ ] Handle tabular format row merges (line-based 3-way)
- [ ] Handle YAML-style format merges
- [ ] Conflict markers for unsolvable conflicts

### 2.4.2 Merge Patterns
- [ ] Row addition: both branches add different rows → union
- [ ] Row deletion: one branch deletes, other modifies → conflict (manual review)
- [ ] Row modification: concurrent field changes → intelligent merge or conflict
- [ ] Field ordering changes: ignore (TOON format resilient to order)

### 2.4.3 Testing & Documentation
- [ ] Unit tests for merge scenarios (3-way merge logic)
- [ ] Integration tests with actual git merges
- [ ] Conflict scenario testing
- [ ] Documentation of merge strategy

## Success Criteria
- Git merge handles TOON conflicts intelligently
- Fewer manual merge conflicts than JSONL
- Round-trip preserved through merges
- All 70+ tests still passing
- Git history stays clean (minimal conflict markers)


Phase 2.3: TOON deletion tracking

Implement deletion tracking in TOON format.

## Overview
Phase 2.2 switched storage to TOON format. Phase 2.3 adds deletion tracking in TOON format for propagating deletions across clones.

## Required Work

### 2.3.1 Deletion Tracking (TOON Format)
- [ ] Implement deletions.toon file (tracking deleted issue records)
- [ ] Add DeleteTracker struct to record deleted issue IDs and metadata
- [ ] Update bdt delete command to record in deletions.toon
- [ ] Design deletion record format (ID, timestamp, reason, hash)
- [ ] Implement auto-prune of old deletion records (configurable TTL)

### 2.3.2 Sync Propagation
- [ ] Load deletions.toon during import
- [ ] Remove deleted issues from local database when imported from remote
- [ ] Handle edge cases (delete same issue in multiple clones)
- [ ] Deletion ordering and conflict resolution

### 2.3.3 Testing
- [ ] Unit tests for deletion tracking
- [ ] Integration tests for deletion propagation
- [ ] Multi-clone deletion scenarios
- [ ] TTL expiration tests

## Success Criteria
- deletions.toon stores deletion records in TOON format
- Deletions propagate across clones via git sync
- Old records auto-prune after TTL
- All 70+ tests still passing
- bdt delete command works seamlessly

bd dep tree doesn't display external dependencies

GetDependencyTree (dependencies.go:464-624) uses a recursive CTE that JOINs with the issues table, which means external refs (external:project:capability) are invisible in the tree output.

When an issue has an external blocking dependency, running 'bd dep tree <id>' won't show it.

Options:
1. Query dependencies table separately for external refs and display them as leaf nodes
2. Add a synthetic 'external' node type that shows the ref and resolution status
3. Document that external deps aren't shown in tree view (use bd show for full deps)

Lower priority since bd show <id> displays all dependencies including external refs.

Implemented: GetDependencyTree now fetches external deps and adds them as synthetic leaf nodes with resolution status. Added test TestGetDependencyTreeExternalDeps. Updated formatTreeNode to display external deps specially.

Thread Test 2

Support redirect files in .beads/ directory

Gas Town creates polecat worktrees with .beads/redirect files that point to a shared beads database. The bd CLI should:

1. When finding a .beads/ directory, check if it contains a 'redirect' file
2. If redirect exists, read the relative path and use that as the beads directory
3. This allows multiple git worktrees to share a single beads database

Example:
- polecats/alpha/.beads/redirect contains '../../mayor/rig/.beads'
- bd commands from alpha should use mayor/rig/.beads

Currently bd ignores redirect files and either uses the local .beads/ or walks up to find a parent .beads/.

Related: gt-nriy (test message that can't be retrieved due to missing redirect support)

Dynamic Molecule Bonding: Fanout patterns for patrol molecules

## Vision

Enable molecules to dynamically spawn child molecules at runtime based on discovered
work. This is the foundation for the "Christmas Ornament" pattern where a patrol
molecule grows arms per-polecat.

## The Activity Feed Vision

Instead of parsing agent logs, users see structured work state:

```
[14:32:08] + patrol-x7k.arm-ace bonded (5 steps)
[14:32:08] + patrol-x7k.arm-nux bonded (5 steps)
[14:32:09] → patrol-x7k.arm-ace.capture in_progress
[14:32:10] ✓ patrol-x7k.arm-ace.capture completed
[14:32:14] ✓ patrol-x7k.arm-ace.decide completed (action: nudge-1)
```

This requires beads to track molecule step state transitions in real-time.

## Key Primitives Needed

### 1. Dynamic Bond with Variables
```bash
bd mol bond mol-polecat-arm <parent-wisp-id> \
  --var polecat_name=ace \
  --var rig=gastown
```

Creates wisp children under the parent:
- parent-id.arm-ace
- parent-id.arm-ace.capture
- parent-id.arm-ace.assess
- etc.

### 2. WaitsFor Directive
```markdown
## Step: aggregate
Collect outcomes from all dynamically-bonded children.
WaitsFor: all-children
Needs: survey-workers
```

The `WaitsFor: all-children` directive makes this a fanout gate - it can't
proceed until ALL dynamically-bonded children complete.

### 3. Activity Feed Query
```bash
bd activity --follow              # Real-time state stream
bd activity --mol <id>            # Activity for specific molecule
bd activity --since 5m            # Last 5 minutes
```

### 4. Parallel Step Detection
Steps with no inter-dependencies should be flagged as parallelizable.
When arms are bonded, their steps can run in parallel across arms.

## Use Case: mol-witness-patrol

The Witness monitors N polecats where N varies at runtime:

```
survey-workers discovers: [ace, nux, toast]
For each polecat:
  bd mol bond mol-polecat-arm <patrol-id> --var polecat_name=<name>
aggregate step waits for all arms to complete
```

This creates the Christmas Ornament shape:
- Trunk: preflight steps
- Arms: per-polecat inspection molecules
- Base: cleanup after all arms complete

## Design Docs

See Gas Town docs:
- docs/molecular-chemistry.md (updated with Christmas Ornament pattern)
- docs/architecture.md (activity feed section)

## Dependencies

This epic may depend on:
- Wisp storage (.beads-wisp/) - already implemented
- Variable substitution in molecules - may need enhancement

All subtasks completed: dynamic bonding (.1), waits-for gates (.2), activity feed (.3), parallel detection (.4)


bd mol bond: Dynamic bond with variable substitution

Implement dynamic molecule bonding with runtime variable substitution.

## Command
```bash
bd mol bond <proto-id> <parent-wisp-id> --var key=value --var key2=value2
```

## Behavior
1. Parse proto molecule template
2. Substitute {{key}} placeholders with provided values
3. Create wisp children under the parent molecule
4. Child IDs follow pattern: parent-id.child-ref (e.g., patrol-x7k.arm-ace)
5. Nested children: parent-id.child-ref.step-ref (e.g., patrol-x7k.arm-ace.capture)

## Variable Substitution
- In step titles: "Inspect {{polecat_name}}" -> "Inspect ace"
- In descriptions: Full template substitution
- In Needs directives: Allow referencing parent steps

## Output
```
✓ Bonded mol-polecat-arm to patrol-x7k
  Created: patrol-x7k.arm-ace (5 steps)
```

Implemented dynamic molecule bonding with --ref flag for custom child IDs (Christmas Ornament pattern)


WaitsFor directive: Fanout gate for dynamic children

Implement WaitsFor directive for molecules that spawn dynamic children.

## Syntax
```markdown
## Step: aggregate
Collect outcomes from all dynamically-bonded children.
WaitsFor: all-children
Needs: survey-workers
```

## Behavior
1. Parse WaitsFor directive during molecule step parsing
2. Track which steps spawn dynamic children (the spawner)
3. Gate step waits until ALL children of the spawner complete
4. Works with bd ready - gate step not ready until children done

## Gate Types
- `WaitsFor: all-children` - Wait for all dynamic children
- `WaitsFor: any-children` - Proceed when first child completes (future)
- `WaitsFor: <step-ref>.children` - Wait for specific spawner's children

## Integration
- bd ready should skip gate steps until children complete
- bd show <mol> should display gate status and child count

Implemented waits-for dependency type with all-children and any-children gates, --waits-for flags, and full test coverage


bd activity: Real-time molecule state feed

Implement activity feed command for watching molecule state transitions.

## Commands
```bash
bd activity --follow              # Real-time streaming
bd activity --mol <id>            # Activity for specific molecule
bd activity --since 5m            # Last 5 minutes
bd activity --type step           # Only step transitions
```

## Output Format
```
[14:32:01] ✓ patrol-x7k.inbox-check completed
[14:32:03] ✓ patrol-x7k.check-refinery completed
[14:32:08] + patrol-x7k.arm-ace bonded (5 steps)
[14:32:09] → patrol-x7k.arm-ace.capture in_progress
[14:32:10] ✓ patrol-x7k.arm-ace.capture completed
[14:32:14] ✓ patrol-x7k.arm-ace.decide completed (action: nudge-1)
[14:32:17] ✓ patrol-x7k.arm-ace COMPLETE
[14:32:23] ✓ patrol-x7k SQUASHED → digest-x7k
```

## Event Types
- `+` bonded - New molecule/step created
- `→` in_progress - Step started
- `✓` completed - Step/molecule finished
- `✗` failed - Step failed
- `⊘` burned - Wisp discarded
- `◉` squashed - Wisp condensed to digest

## Implementation
- Could use SQLite triggers or polling
- --follow uses OS file watching or polling
- Filter by mol ID, type, time range

Implemented bd activity command with real-time feed, filtering, and new mutation event types


Parallel step detection in molecules

Detect and flag parallelizable steps in molecules.

## Detection Rules
Steps can run in parallel when:
1. No Needs dependencies between them
2. Not in same sequential chain
3. Across dynamic arms (arm-ace and arm-nux can parallelize)

## Output in bd mol show
```
patrol-x7k (mol-witness-patrol)
├── inbox-check [completed]
├── survey-workers [completed]
│   ├── arm-ace [parallel group A]
│   │   ├── capture [can parallelize]
│   │   ├── assess [needs: capture]
│   │   └── execute [needs: assess]
│   └── arm-nux [parallel group A]
│       ├── capture [can parallelize]
│       └── ...
├── aggregate [gate: waits for all-children]
```

## Flags
- `bd mol show <id> --parallel` - Highlight parallel opportunities
- `bd ready --mol <id>` - List all steps that can run now

## Future: Parallel Execution Hints
For agents using Task tool subagents:
- Identify independent arms that can run simultaneously
- Suggest parallelization strategy

Implemented --parallel flag for bd mol show and --mol flag for bd ready


Remove legacy autoflush code paths

## Problem

The autoflush system has dual code paths - an old timer-based approach and a new FlushManager. Both are actively used based on whether flushManager is nil.

## Locations

- main.go:78-81: isDirty, needsFullExport, flushTimer marked 'used by legacy code'
- autoflush.go:291-369: Functions with 'Legacy path for backward compatibility with tests'

## Current Behavior

```go
// In markDirtyAndScheduleFlush():
if flushManager != nil {
    flushManager.MarkDirty(false)
    return
}
// Legacy path for backward compatibility with tests
```

## Proposed Fix

1. Ensure flushManager is always initialized (even in tests)
2. Remove the legacy timer-based code paths
3. Remove isDirty, needsFullExport, flushTimer globals
4. Update tests to use FlushManager

## Risk

Low - the FlushManager is the production path. Legacy code only runs when flushManager is nil (test scenarios).

Removed legacy autoflush code: isDirty, needsFullExport, flushTimer globals and flushToJSONL() wrapper. FlushManager is now the only code path.


Restart daemon with 0.33.2

Restart the bd daemon to pick up new version:

```bash
bd daemon --stop
bd daemon --start
bd daemon --health  # Verify Version: 0.33.2
```


Issue lifecycle hooks (on-close, on-complete)

Add hooks that fire on issue state transitions, enabling automation like closing linked GitHub issues.

## Problem

We have `external_ref` to link beads issues to external systems (GitHub, Linear, Jira), but no mechanism to trigger actions when issues close. Currently:

```
bd-u2sc (external_ref: gh-692) closes → nothing happens
```

## Proposed Solution

### Phase 1: Shell Hooks

Add `.beads-hooks/on-close.sh` (and similar lifecycle hooks):

```bash
# .beads-hooks/on-close.sh
# Called by bd close with issue JSON on stdin
#\!/bin/bash
issue=$(cat)
external_ref=$(echo "$issue" | jq -r '.external_ref // empty')
if [[ "$external_ref" == gh-* ]]; then
    number="${external_ref#gh-}"
    gh issue close "$number" --repo steveyegge/beads \
      --comment "Completed via beads epic $(echo $issue | jq -r .id)"
fi
```

### Lifecycle Events

| Event | Trigger | Use Cases |
|-------|---------|-----------|
| `on-close` | Issue closed | Close external refs, notify, archive |
| `on-complete` | Epic children all done | Roll-up completion, close parent refs |
| `on-status-change` | Any status transition | Sync to external systems |

### Phase 2: Molecule Completion Handlers

Molecules could define completion actions:

```yaml
name: github-issue-tracker
on_complete:
  - action: shell
    command: gh issue close {{external_ref}} --repo {{repo}}
  - action: mail
    to: mayor/
    subject: "Epic {{id}} completed"
```

### Phase 3: Gas Town Integration

For full Gas Town deployments:
- Witness observes closures via beads events
- Routes to integration agents via mail
- Agents handle external system interactions

## Implementation Notes

- Hooks should be async (don't block bd close)
- Pass full issue JSON to hook via stdin
- Support hook timeout and failure handling
- Consider `--no-hooks` flag for bulk operations

## Related

- `external_ref` field already exists (GH#142)
- Cross-project deps: bd-h807, bd-d9mu
- Git hooks: .beads-hooks/ pattern established

## Use Cases

1. **GitHub integration**: Close GH issues when beads epic completes
2. **Linear sync**: Update Linear status when beads status changes
3. **Notifications**: Send mail/Slack when high-priority issues close
4. **Audit**: Log all closures to external system

Molecules already cover this use case. Completion actions should be encoded as tail steps in molecules rather than lifecycle hooks. This keeps everything in the beads data plane, makes it resumable/auditable, and allows tiered delegation (haiku for simple steps). Hooks would escape the ledger and add a parallel system without clear benefit.


Refactor duplicate JSONL-from-git parsing code

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

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

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

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

Auto-detect identity from directory context for bd mail

Currently bd mail inbox defaults to git user name, requiring --identity flag with exact format.

## Problem
- Mail sent to `gastown/crew/max`
- Max runs `bd mail inbox` → defaults to 'Steve Yegge' (git user)
- Max must know to use `--identity 'gastown/crew/max'` with exact slashes

## Proposed Fix
Auto-detect identity from directory context when in a Gas Town workspace:
- In `/Users/stevey/gt/gastown/crew/max`, infer identity = `gastown/crew/max`
- Pattern: `<town>/<rig>/<role>/<name>` → `<rig>/<role>/<name>`

## Additional Improvements
1. Support GT_IDENTITY env var (set by gt crew at / session spawning)
2. Support identity in .beads/config.yaml
3. Normalize format: accept both slashes and dashes as equivalent

## Context
Discovered during crew-to-crew work assignment. Max couldn't see mail despite correct nudge because identity defaulted wrong.

Fix checkExistingBeadsData to be worktree-aware

The checkExistingBeadsData function in cmd/bd/init.go checks for .beads in the current working directory, but for worktrees it should check the main repository root instead. This prevents proper worktree compatibility.


Add bd doctor --fix flag to automatically repair issues

Add bd doctor --fix flag to automatically repair detected issues.

## Current State
- Doctor checks return issues with "Fix" field containing fix instructions
- No automatic fix execution
- User must manually follow fix instructions

## Implementation

### 1. Add --fix flag to doctor.go
```go
// In cmd/bd/doctor.go init()
doctorCmd.Flags().Bool("fix", false, "Automatically fix detected issues")
doctorCmd.Flags().Bool("yes", false, "Skip confirmation prompts (use with --fix)")
```

### 2. Create fix registry (cmd/bd/doctor/fix/registry.go)
```go
package fix

// Fixer can automatically repair an issue
type Fixer interface {
    // CanFix returns true if this fixer handles the given check name
    CanFix(checkName string) bool
    // Fix attempts to repair the issue, returns error if failed
    Fix(ctx context.Context, issue *CheckResult) error
    // Description returns human-readable description of what will be fixed
    Description() string
}

var registry []Fixer

func Register(f Fixer) {
    registry = append(registry, f)
}

func GetFixer(checkName string) Fixer {
    for _, f := range registry {
        if f.CanFix(checkName) {
            return f
        }
    }
    return nil
}
```

### 3. Implement fixers (one per file)

**cmd/bd/doctor/fix/hooks.go**
```go
type HooksFixer struct{}

func (f *HooksFixer) CanFix(name string) bool {
    return name == "git-hooks" || name == "hooks-outdated"
}

func (f *HooksFixer) Fix(ctx context.Context, issue *CheckResult) error {
    return hooks.Install(".", true) // force reinstall
}

func (f *HooksFixer) Description() string {
    return "Reinstall git hooks"
}

func init() {
    Register(&HooksFixer{})
}
```

**cmd/bd/doctor/fix/sync_branch.go**
```go
type SyncBranchFixer struct{}

func (f *SyncBranchFixer) CanFix(name string) bool {
    return name == "sync-branch-missing" || name == "sync-branch-diverged"
}

func (f *SyncBranchFixer) Fix(ctx context.Context, issue *CheckResult) error {
    // Reset to remote or create branch
    return syncbranch.ResetToRemote(ctx, repoRoot, branch, jsonlPath)
}
```

**cmd/bd/doctor/fix/merge_driver.go**
```go
type MergeDriverFixer struct{}

func (f *MergeDriverFixer) CanFix(name string) bool {
    return name == "merge-driver-missing" || name == "merge-driver-outdated"
}

func (f *MergeDriverFixer) Fix(ctx context.Context, issue *CheckResult) error {
    return setupMergeDriver()
}
```

### 4. Update doctor run logic

```go
func runDoctor(cmd *cobra.Command, args []string) {
    issues := runAllChecks()

    if \!fixFlag {
        // Existing behavior - just display issues
        displayIssues(issues)
        return
    }

    // Collect fixable issues
    var fixable []FixableIssue
    for _, issue := range issues {
        if fixer := fix.GetFixer(issue.CheckName); fixer \!= nil {
            fixable = append(fixable, FixableIssue{issue, fixer})
        }
    }

    if len(fixable) == 0 {
        fmt.Println("No automatically fixable issues found")
        return
    }

    // Show what will be fixed
    fmt.Printf("Found %d fixable issues:\n", len(fixable))
    for i, f := range fixable {
        fmt.Printf("  %d. [%s] %s\n", i+1, f.Issue.CheckName, f.Fixer.Description())
    }

    // Confirm unless --yes
    if \!yesFlag {
        fmt.Print("\nProceed with fixes? [Y/n] ")
        // ... read confirmation
    }

    // Apply fixes
    for _, f := range fixable {
        fmt.Printf("Fixing %s... ", f.Issue.CheckName)
        if err := f.Fixer.Fix(ctx, f.Issue); err \!= nil {
            fmt.Printf("FAILED: %v\n", err)
        } else {
            fmt.Println("OK")
        }
    }
}
```

## Fixable Checks (Initial Set)

| Check | Fixer | Action |
|-------|-------|--------|
| git-hooks | HooksFixer | Reinstall hooks |
| hooks-outdated | HooksFixer | Update hooks |
| merge-driver-missing | MergeDriverFixer | Configure merge driver |
| sync-branch-diverged | SyncBranchFixer | Reset to remote |
| daemon-version-mismatch | DaemonFixer | Restart daemon |

## Testing
```bash
# Test with broken hooks
rm .git/hooks/pre-commit
bd doctor --fix --yes

# Verify fix applied
bd doctor  # Should pass now
```

## Success Criteria
- --fix flag triggers automatic repair
- User prompted for confirmation (unless --yes)
- Clear output showing what was fixed
- Graceful handling of fix failures
- At least 5 common issues auto-fixable

Feature already fully implemented. Verified: --fix, --yes, --interactive, --dry-run flags all working. 20+ fixable issues supported. Tests pass.


Add gate timeout tracking and notification

Implement timeout and notification logic for gates.

## Timeout Behavior
1. Gate created with timeout (e.g., 30m)
2. Deacon tracks elapsed time during patrol
3. If timeout reached:
   - Notify all waiters: "Gate timed out"
   - Close gate with timeout reason
   - Waiter can retry, escalate, or fail gracefully

## Notification
- Use gt mail send to notify waiters
- Include gate ID, await type, and reason in message
- Support multiple waiters notification

## Escalation Path
- Witness sees stuck worker, nudges them
- Worker can escalate to human if needed

bd list --parent: filter by parent issue

Add --parent flag to bd list to filter issues by parent.

Example:
```bash
bd list --parent=gt-h5n --status=open
```

Would show all open children of gt-h5n.

Useful for:
- Checking epic progress
- Finding swarmable work within an epic
- Molecule step listing

Implemented --parent flag for bd list. Filters children by parent issue using parent-child dependencies.

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

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

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

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

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

## Potential Followups
See linked issues for suggestions.


bd delete --from-file should add deleted issues to deletions manifest

When using bd delete --from-file to bulk delete issues, the deleted issue IDs are not being added to the deletions.jsonl manifest.

This causes those issues to be resurrected during bd sync when git history scanning finds them in old commits.

Expected: All deleted issues should be added to deletions.jsonl so they wont be reimported from git history.

Workaround: Manually add deletion records to deletions.jsonl.


Add --pinned and --no-pinned flags to bd list

Add filtering flags to bd list: --pinned shows only pinned issues, --no-pinned excludes pinned issues. Default behavior shows all issues with a pin indicator.

Already implemented - --pinned and --no-pinned flags exist in bd list


bd mail uses git user.name for sender instead of BEADS_AGENT_NAME

When sending mail via `bd mail send`, the sender field in the stored issue uses git config user.name instead of the BEADS_AGENT_NAME environment variable.

Reproduction:
1. Set BEADS_AGENT_NAME=gastown-alpha
2. Run: bd mail send mayor/ -s 'Test' -m 'Body'
3. Check the issue.jsonl: sender is 'Steve Yegge' (git user.name) not 'gastown-alpha'

Expected: The sender field should use BEADS_AGENT_NAME when set.

This breaks the mail system for multi-agent workflows where agents need to identify themselves by their role (polecat, refinery, etc.) rather than the human user's git identity.

Related: gt mail routing integration with Gas Town


gt polecat done should auto-stop running session

Currently 'gt polecat done' fails if session is running, requiring a separate 'gt session stop' first. This is unnecessary friction - done should just stop the session automatically since that's always what you want.

Moving to gastown - this is a gt issue not bd


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

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


bd ready resolves external dependencies

Extend bd ready to check external blocked_by references:

1. Parse external:<project>:<capability> from blocked_by
2. Look up project path from external_projects config
3. Check if target project has provides:<capability> label on a closed issue
4. If not satisfied, issue is blocked

Example output:
```bash
bd ready
# gt-xyz: blocked by external:beads:mol-run-assignee (not provided)
# gt-abc: ready
```

Depends on: bd-om4a (external: prefix), bd-66w1 (config)

Part of cross-project dependency system.
See: gastown/docs/cross-project-deps.md

Implemented external dep resolution in GetReadyWork - filters issues with unsatisfied external:project:capability deps


Deferred HOP schema additions (P2/P3)

Deferred from bd-7pwh after review. Add when semantics are clearer and actually needed:

- assignee_ref: Structured EntityRef alongside string assignee
- work_type: 'mutex' vs 'open_competition' (everything is mutex in v0.1)
- crystallizes: bool for work that compounds vs evaporates (can derive from issue_type)
- cross_refs: URIs to beads in other repos (needs federation first)
- skill_vector: []float32 embeddings placeholder (YAGNI)

These can be added later without breaking changes (all optional fields).


Investigate incremental blocked_issues_cache updates at scale

Current blocked_issues_cache strategy does full DELETE + INSERT on every dependency/status change.

**Problem at scale:**
- 10K issues: ~50ms rebuild (acceptable)
- 100K issues: ~500ms rebuild (noticeable)
- 1M issues: multi-second rebuilds (problematic)

**Current implementation (blocked_cache.go:104-154):**
- DELETE FROM blocked_issues_cache
- INSERT with recursive CTE

**Potential optimizations:**
1. **Incremental updates:** Only add/remove affected issue IDs instead of full rebuild
2. **Dirty tracking:** Skip rebuild if cache is already valid
3. **Async rebuild:** Rebuild in background, serve stale cache briefly
4. **Partial invalidation:** Only invalidate affected subtree

**Decision needed:** Is this premature optimization? Current target is <100K issues.

**Benchmark:** Add benchmark for cache rebuild at 100K scale to measure actual impact.


Run bd doctor at end of bd init to verify setup

Run bd doctor diagnostics at end of bd init (after line 398 in init.go). If issues found, warn user immediately: '⚠ Setup incomplete. Run bd doctor --fix to complete setup.' Catches configuration problems before user encounters them in normal workflow.

Already implemented in commits ec4117d0 and 3a36d0b9 - hooks/merge driver install by default, doctor runs at end of init
