# PDCA Fast Track — Daniel's Track

> v2.1.11 Sprint β FR-β5. Wraps `lib/control/fast-track.js`. Provides a
> single auto-escalation gate for users who have already earned Trust
> ≥ 80 and produced a Design doc — Checkpoints 1-8 default to
> Recommended without prompting. Falls back to L2 + manual review the
> moment any preconditions fails (E-β5-01 / E-β5-02).

## Arguments

| Argument | Description | Example |
|----------|-------------|---------|
| `<feature>` | Feature name to engage fast-track for | `/pdca-fast-track bkit-v2111-integrated-enhancement` |

## Behavior

### Preconditions (all must pass; fail-open)

1. **Config enabled** — `bkit.config.json#control.fastTrack.enabled === true`
2. **Trust Score ≥ 80** — `.bkit/state/trust-profile.json#trustScore`
   ≥ `fastTrack.minTrustScore` (default 80)
3. **Design doc exists** — resolved via `bkit.config.json#pdca.docPaths.design`
   templates against `<feature>`

When any block, surface the reason with a remedy hint:

| Block | Remedy hint |
|-------|-------------|
| `disabled_in_config` | "Set `control.fastTrack.enabled = true` in bkit.config.json" |
| `trust_score_too_low` | "Run a few `/pdca check` cycles to raise trust" |
| `design_doc_missing` | "Run `/pdca design <feature>` first" |

### On engage (all preconditions pass)

1. Recommend Automation Level escalation L2 → `fastTrack.autoLevel`
   (default `L3`).
2. Persist engagement record to `.bkit/runtime/fast-track-log.json`:
   ```json
   {
     "engaged": true,
     "feature": "<feature>",
     "engagedAt": "<ISO>",
     "trustScore": 85,
     "autoLevel": "L3",
     "fallbackLevel": "L2",
     "skipCheckpoints": [1,2,3,4,5,6,7,8],
     "designPath": "docs/02-design/features/<feature>.design.md",
     "decisions": []
   }
   ```
3. Each Checkpoint 1-8 invocation calls `fast-track.recordCheckpoint`
   to append a decision entry (audit trail).
4. If a Checkpoint surfaces NO "Recommended" option, call
   `recordCheckpoint({ decision: 'fallback', reason: 'no_recommended' })`
   and pause to `fallbackLevel`.

## Security

- All file IO is rooted at `process.env.CLAUDE_PROJECT_DIR` (or repo root).
- Audit log JSON is OWASP A08-clean: no user-controlled keys; only
  whitelisted `checkpoint` (number), `decision` (enum), `reason`
  (sanitized string).
- Design doc patterns are read from `bkit.config.json` — no traversal
  via untrusted `feature` arg (pattern is `{feature}` placeholder only).
- Trust score read is fail-safe: missing file returns 0 (blocks engage).

## Module Dependencies

| Module | Function | Usage |
|--------|----------|-------|
| `lib/control/fast-track.js` | `evaluatePreconditions(feature)` | Block list |
| `lib/control/fast-track.js` | `engage(feature)` | Audit + record |
| `lib/control/fast-track.js` | `recordCheckpoint({...})` | Per-CP decision |
| `lib/control/fast-track.js` | `isCheckpointSkipped(n)` | Should we skip? |

## Examples

```bash
# Engage on a Design-complete feature
/pdca-fast-track bkit-v2111-integrated-enhancement

# Result if Trust < 80
# Block: trust_score_too_low (current 68 < required 80)

# Result if Design missing
# Block: design_doc_missing → run /pdca design first
```
