## Summary
Introduces a configurable workflow state machine that replaces all hardcoded
state labels. The default workflow matches current behavior exactly, ensuring
backward compatibility.
## Architecture
### lib/workflow.ts — Core workflow engine
XState-style statechart configuration:
```typescript
type StateConfig = {
type: 'queue' | 'active' | 'hold' | 'terminal';
role?: 'dev' | 'qa';
label: string;
color: string;
priority?: number;
on?: Record<string, TransitionTarget>;
};
```
All behavior is derived from the config:
- Queue states: `type: 'queue'`, grouped by role, ordered by priority
- Active states: `type: 'active'` — worker occupied
- Transitions: defined with optional actions (gitPull, detectPr, closeIssue, reopenIssue)
- Labels and colors: derived from state.label and state.color
### Derivation functions
- `getStateLabels()` — all labels for issue tracker sync
- `getLabelColors()` — label → color mapping
- `getQueueLabels(role)` — queue labels for a role, ordered by priority
- `getActiveLabel(role)` — the active/in-progress label for a role
- `getRevertLabel(role)` — queue label to revert to on failure
- `detectRoleFromLabel()` — detect role from a queue label
- `getCompletionRule(role, result)` — derive transition rule from config
## Files Changed
- **lib/workflow.ts** — NEW: workflow engine and default config
- **lib/providers/provider.ts** — deprecate STATE_LABELS, LABEL_COLORS; derive from workflow
- **lib/providers/github.ts** — use workflow config for label operations
- **lib/providers/gitlab.ts** — use workflow config for label operations
- **lib/services/pipeline.ts** — use getCompletionRule() from workflow
- **lib/services/tick.ts** — use workflow for queue/active labels
- **lib/services/health.ts** — use workflow for active/revert labels
- **lib/tools/work-start.ts** — use workflow for target label
## Backward Compatibility
- DEFAULT_WORKFLOW matches current hardcoded behavior exactly
- Deprecated exports kept for any external consumers
- No breaking changes to tool interfaces or project state
## Future Work
- Load per-project workflow overrides from projects.json
- User-facing config in projects/workflow.json
- Tool schema generation from workflow states
