 # Sealed-Envelope Testing Protocol
 
+> **Canonical specification:** [Gap Score Spec v1.0.0](https://github.com/DUBSOpenHub/gap-score-spec/blob/main/SPEC.md)
+> Dark Factory is the reference Level 3 implementation.
+
 ## Purpose
 
 The sealed-envelope protocol ensures that the quality assessment of factory-built code is independent and unbiased. Tests are generated from the specification BEFORE code is written, and building agents NEVER see the sealed tests.

Subject: [PATCH 2/5] fix: align docs with config.yml, fix sealed protocol
 gaps, add hardening payload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- README: config section now matches config.yml (factory/safety keys, correct defaults)
- README: express mode pipeline includes Phase 5 (hardening when gap > 0%)
- README: state file documents checkpoint structured format and evaluation_due_at

 # Copilot Instructions — Dark Factory
 
-This repository contains the **Dark Factory** Copilot CLI skill — an agentic build system that orchestrates specialist AI agents through a sealed-envelope testing pipeline.
+This repository contains **Dark Factory**, a GitHub Copilot CLI skill that orchestrates an agent pipeline with **sealed-envelope testing**.
 
-## Key Concepts
+## File map
 
-- **Sealed-envelope testing**: QA agent generates tests from the PRD *before* code is written. Building agents never see these tests. The gap between builder tests and sealed tests measures build quality.
-- **Checkpoint-gated pipeline**: Each phase runs autonomously, pausing for human approval at phase boundaries.
-- **Git worktree isolation**: All building happens in an isolated worktree. Nothing touches the user's working directory until they approve.
+| File/Dir | Purpose |
+|---|---|
+| `SKILL.md` | Factory Manager orchestrator prompt (the brain) |
+| `agents/*.md` | Specialist agent prompts |
+| `templates/*.md` | Artifact output formats |
+| `protocols/*.md` | Protocol invariants (sealed envelope, checkpoints) |
+| `config.yml` | Tunables (models, thresholds, timeouts) |
+| `catalog.yml` | Skill metadata + file references |
+| `docs/TESTING.md` | Playbooks + QA checklist |
+| `docs/ADR.md` | Why these decisions |
 
-## File Map
+## Non-negotiables
 
-| File | Purpose |
-|------|---------|
-| `SKILL.md` | Factory Manager orchestrator prompt (the brain) |
-| `catalog.yml` | Skill metadata for Copilot CLI registration |
-| `config.yml` | Tunable settings (models, thresholds, checkpoints) |
-| `agents/*.md` | Specialist agent prompts (product, arch, qa, eng) |
-| `templates/*.md` | Structured output templates for agent artifacts |
-| `protocols/*.md` | Reusable protocol definitions |
-
-## Rules
-
-1. **Never modify sealed test isolation** — the sealed directory must remain invisible to building agents
-2. **Agents are stateless** — each `task()` call gets a clean context. Pass EXACTLY what the agent needs via the handoff manifest.
-3. **State must survive crashes** — every phase transition writes to `state.json`
-4. **Express mode must work** — quick tasks should complete in ~60 seconds with one checkpoint
-5. **Keep agent prompts under 200 lines** — focused, not bloated
+1. **Sealed envelope is sacred.** The Lead Engineer must never see sealed tests; the QA Sealed agent must never see code.
+2. **Config is the source of truth.** Never hardcode model names or tunables inside prompts.
+3. **Agent prompts <= 200 lines.** If a prompt grows, split responsibilities instead.
+4. **Just a skill.** Do not add runtime code, package managers, telemetry, dashboards, or plugin systems.
+5. **Worktree isolation.** All build work happens under `.factory/` until delivery approval.
+
+## Prohibited actions
+
+- Exposing sealed test contents to the user before Phase 4.
+- Passing sealed test source code into any builder/hardening prompt.
+- Editing user files outside the factory worktree.
+
+## PR requirements
+
+Before opening a PR:
+
+- Run Playbook 1 (Full) and Playbook 2 (Express) from `docs/TESTING.md`.
+- Ensure `catalog.yml` references are valid.
+- Ensure YAML parses (`config.yml`, `catalog.yml`).
+- Ensure CI validate workflow passes.

+
+All notable changes to the **Dark Factory** project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

+## [0.1.0] - 2026-02-24
+
+### Added
+
+- **Core Pipeline:** 6-phase autonomous build system (Product Manager -> Architect -> QA Sealed -> Lead Engineer -> QA Validator -> Delivery).
+- **Sealed-Envelope Testing:** Acceptance tests are generated from the PRD before implementation and kept hidden from the builder.
+- **Modes:** Full (checkpoint-gated) and Express (fast run with one delivery checkpoint).
+- **Outcome Evaluation:** Optional post-ship evaluation against PRD success criteria.
+- **Configuration:** `config.yml` for model routing and factory tunables.
+- **CI:** Validation workflow for YAML, markdown linting, prompt line counts, and catalog reference checks.

+# Contributing to 🏭 Dark Factory
+
+Thanks for helping keep the factory lights out. This repo is a Copilot CLI skill (Markdown + YAML), so changes are mostly prompt and workflow edits.
+
+## Core principles
+
+1. **Sealed envelope is sacred:** QA Sealed must never see code; Lead Engineer must never see sealed tests.
+2. **Config is the source of truth:** Tunables and model routing belong in `config.yml`.
+3. **Just-right engineering:** No package.json/pyproject.toml; keep this repo prompt-only.
+4. **200-line rule:** Keep each agent prompt under 200 lines.
+
+## Workflow
+
+1. Fork the repo and create a branch: `factory/<topic>`.
+2. Make the smallest change required.
+3. Update docs/templates when outputs change.
+4. Run the playbooks in `docs/TESTING.md` (Full + Express at minimum).
+5. Ensure CI validation would pass (see `.github/workflows/validate.yml`).
+6. Open a PR and fill out `.github/PULL_REQUEST_TEMPLATE.md`.
+
+## Modifying agents
+
+- Change **one agent at a time** unless a change is strictly coupled.
+- Prompts must declare explicit **inputs and outputs**.
+- Never reference sealed directories from builder prompts.
+
+## Reporting issues

-# 🏭 Dark Factory
-
-**Agentic AI build system with sealed-envelope testing.** Give it a goal — it delivers production-ready, tested code.
-
-Dark Factory orchestrates 5 specialist AI agents through a checkpoint-gated pipeline. A sealed test suite is generated from the spec *before* code is written — building agents never see these tests. The gap between their tests and the sealed tests measures true build quality.

+
+Dark Factory is a GitHub Copilot CLI skill that turns a short free-text goal into a production-grade pull request. It isolates the work in a disposable git worktree, orchestrates six specialist agents, and measures quality with sealed-envelope testing — builders never see the hidden acceptance suite that judges them.

+
+## Why Sealed-Envelope Testing?
+Sealed testing creates a blindfolded QA loop: the QA Sealed agent writes acceptance tests before any code exists, hides them in `.factory/sealed/`, and the builder never sees them. The quality gap between sealed tests and the engineer's tests reveals whether the build is trustworthy.
+
+**Benefits**
+- **Prevents overfitting.** Builders can’t “teach to the test” because they never see the sealed suite.
+- **Quantifies quality.** Gap scores (sealed failures ÷ sealed total) expose blind spots numerically.
+- **Automates escalation.** Hardening cycles fire automatically, but the engineer still sees only failure messages.
+- **Retains speed.** Express mode still produces sealed tests immediately after setup, so even fast fixes retain coverage.
+
+**Comparison**
+| Approach | What builders see | When tests are written | Blind-spot risk |
+|----------|------------------|------------------------|-----------------|
+| Classic TDD | Entire suite | During implementation | Spec drift if requirements change mid-build |
+| Manual QA | Human docs | Post-build | Slow feedback, inconsistent coverage |
+| **Dark Factory** | Only failure messages | Before Phase 3, hidden until validation | Gap score proves whether the spec was truly covered |

+
+## Command Reference
+| Command | Purpose |
+|---------|---------|
+| `dark factory — <goal>` | Full pipeline (Phases 0–6) with checkpoints at every phase. |
+| `dark factory express — <goal>` | Skips PRD/ARCH, still seals tests from the raw goal, single checkpoint at delivery. |
+| `dark factory resume` | Reloads the most recent `state.json` and continues from the saved phase. |
+| `dark factory status` | Prints `state.json` plus any pending outcome evaluations without mutating state. |
+| `dark factory evaluate <run-id>` | Launches Phase 7 Outcome Evaluator for an archived run. |
+| `dark factory premium — <goal>` | Routes all agents through `config.models.premium_model` for one run. |
+
+## Installation & Setup
+### Prerequisites
+- Git 2.35+ with worktree support.
+- GitHub Copilot CLI `>= 0.13.0` (skills `/skills add` available).
+- Python 3.10+ and Node 18+ if you want to run the validation workflow locally.
+
+### Steps
+1. **Clone**: `git clone https://github.com/DUBSOpenHub/dark-factory.git && cd dark-factory`
+2. **Register the skill**: `/skills add .`
+3. **Tune `config.yml`** (models, limits, logging).
+4. **Smoke test**: `dark factory express — say hello world` to ensure isolation + sealed QA works.
+5. **Optional**: install markdownlint + yamllint to reproduce CI locally.
+
+## Configuration Reference
+Dark Factory reads `config.yml` on every run and never hardcodes tunables.
+
+### `factory`
+| Key | Default | Purpose |
+|-----|---------|---------|
+| `default_mode` | `full` | Pipeline used when the goal doesn’t specify express. |
+| `max_hardening_cycles` | `3` | Number of automatic hardening loops before escalation. |
+| `express_threshold_words` | `15` | Goals shorter than this switch to express mode automatically. |
+| `agent_timeout_sec` | `300` | Cancels any agent call that runs longer than this many seconds. |
+| `max_retries` | `1` | Automatic retries for transient agent failures/timeouts. |
+| `verbosity` | `info` | Logging level for factory status output (`debug`, `info`, `warn`, `error`). |
+
+### `safety`
+| Key | Default | Purpose |
+|-----|---------|---------|
+| `max_prd_lines` | `180` | Caps PRD.md to stay within downstream context windows. |
+| `max_artifact_lines` | `600` | Cap for ARCH, GAP reports, and other artifacts. |
+
+### `isolation`
+| Key | Default | Purpose |
+|-----|---------|---------|
+| `workspace_root` | `.factory` | Root directory for worktrees and sealed tests. |
+| `branch_prefix` | `factory/` | Branch prefix used for each run. |
+| `sealed_dir` | `.factory/sealed` | Storage for hidden tests; never checked out into the worktree. |
+| `state_file` | `.factory/state.json` | Crash-recovery ledger. |
+
+### `models`
+| Key | Default | Purpose |
+|-----|---------|---------|
+| `product_mgr` | `claude-sonnet-4.6` | PRD author. |
+| `architect` | `claude-sonnet-4.6` | System designer. |
+| `qa_sealed` | `claude-sonnet-4.6` | Hidden test author. |
+| `lead_eng` | `claude-sonnet-4.6` | Builder + hardening. |
+| `qa_validator` | `claude-haiku-4.5` | Sealed test runner. |
+| `outcome_evaluator` | `claude-sonnet-4.6` | Phase 7 analyst. |
+| `premium_model` | `claude-opus-4.6` | Override when the user says “premium.” |
+
+### `checkpoints`
+| Key | Default | Purpose |
+|-----|---------|---------|
+| `gates` | `after_prd`, `after_arch`, `after_build`, `after_validation`, `delivery` | Human decision points. Express keeps only `delivery`. |
+| `allow_skip_all` | `true` | If true, users can auto-approve everything **except** final delivery. |
+
+### `outcome_evaluation`
+| Key | Default | Purpose |
+|-----|---------|---------|
+| `auto_evaluate_after_days` | `0` | Auto Phase 7 schedule (0 disables automation). |
+| `archive_dir` | `.factory/archive` | Storage for PRD/ARCH/GAP consumed by Phase 7. |
+
+## Usage Examples
+### 1. Full build (“Lights Out”)
 ```
+dark factory — build a CLI that audits dependencies for GPL licenses
+```
+Expected output snippet:
+```
+🏭 Run: run-20260401-1215 | Mode: FULL
+🏭 Phase 2 🔒 SHA-256 (sealed tests): sha256:d3b1...
+🏭 GAP_SCORE: 11.1% (2 sealed failures)
+🏭 Delivery report ready — approve / reject
+```
+Tips: provide scope (“CLI”, “API”) so the PRD agent knows what to model; use checkpoints to add clarifications without restarting.
 
-## The Sealed Envelope
-
-The core innovation. Before any code is written:
-
-1. **QA Sealed agent** reads only the PRD (never code)
-2. Writes behavioral tests → stored in a **sealed directory**
-3. Building agents **never see these tests**
-4. After code is built, sealed tests are run against it
-5. The **gap score** (sealed failures / total) measures true quality
-6. During hardening, the engineer sees only "test X failed" — never the test code
-
-This prevents "teaching to the test" and measures genuine engineering quality.
-
-## Two Modes
-
-| Mode | When | Phases | Checkpoints |
-|------|------|--------|-------------|
-| **Full** | New features, projects | 0→1→2→3→4→5→6 | After each phase |
-| **Express** | Quick fixes, small tasks | 0→3→4→6 | Delivery only |
-
-## Agent Team
-
-| Agent | Role | Sees |
-|-------|------|------|
-| Product Manager | Writes PRD from goal | User goal + repo context |
-| Architect | Designs system | PRD only |
-| QA Sealed | Writes hidden tests | PRD only (never code) |
-| Lead Engineer | Implements code + tests | PRD + Architecture (never sealed tests) |
-| QA Validator | Runs all tests, gap analysis | Everything |
-
-## Configuration
-
-Edit `config.yml` to tune:
-- Default mode (full/express)
-- Model routing per agent (Speed Stack)
-- Max hardening cycles
-- Checkpoint gates
+### 2. Express fix
+```
+dark factory express — add rate limiting middleware to REST API
+```
+Expected output snippet:
+```
+🏭 Mode switched to EXPRESS (goal length=8 words)
+🏭 QA Sealed (express) derived acceptance criteria from raw goal
+🏭 Phase 6 — delivery checkpoint (only gate)
+```
+Use express for quick hardening tasks or doc-only fixes. Sealed QA still runs from the goal text.
 
----
+### 3. Outcome evaluation
+```
+dark factory evaluate run-20260401-1215
+```
+Expected output snippet:
+```
+🏭 OUTCOME EVALUATION — Run run-20260401-1215
+🏭 PRD Criteria Met: 6/7 | KPIs On Track: 2/3
+🏭 Outcome Score: 75/100
+```
+If `auto_evaluate_after_days > 0`, the factory will prompt you when a run is due even without this command.
+
+## Architecture Overview
+- **Factory Manager (SKILL.md):** Loads config, determines mode, routes each `task()` call to the right model with guardrails (timeouts, retries, artifact caps) and surfaces checkpoints.
+- **Agent Team:** Product Manager → Architect & QA Sealed (parallel) → Lead Engineer → QA Validator → Outcome Evaluator. Agents are stateless and only receive what the orchestrator passes via the handoff manifest.
+- **Isolation:** Every run lives in `.factory/runs/<run-id>` plus a hidden `.factory/sealed/<run-id>` folder. Aborting deletes both the worktree and the branch immediately.
+- **State & Telemetry:** `state.json` persists mode, phase, artifacts, sealed hash, checkpoint decisions, and `evaluation_due_at`. SQLite tables (`factory_runs`, `phase_results`) enable reporting and future analytics.
+- **Templates & Protocols:** Agents follow the markdown templates in `templates/` and the governance rules in `protocols/`, ensuring consistent artifacts (PRD, ARCH, GAP report, delivery summary, outcome report).
+
+## Factory Operating Manual
+### Sealed Test Lifecycle
+1. **Authoring (Phase 2a or Express QA):** QA Sealed writes runnable tests using only PRD text or raw goals, capped at `max_artifact_lines`.
+2. **Hashing:** The Factory Manager records a SHA-256 hash of every sealed file and stores it in `state.json`.
+3. **Vault Storage:** Files live under `.factory/sealed/<run-id>` and are never copied into the worktree until validation.
+4. **Execution:** During Phase 4 the sealed suite is temporarily copied into the worktree, executed, then deleted immediately after QA Validator reports the gap score.
+5. **Archive:** On delivery approval, the sealed files plus PRD/ARCH/GAP reports are archived under `.factory/archive/<run-id>` for future outcome evaluations.
+
+### State File Anatomy
+| Key | Meaning | Example |
+|-----|---------|---------|
+| `run_id` | Unique identifier for the current build | `run-20260401-1215` |
+| `mode` | `full` or `express` | `full` |
+| `current_phase` | Phase index (0–6) | `3` |
+| `sealed_hash` | Integrity check for hidden tests | `sha256:d3b1...` |
+| `checkpoints` | Map of checkpoint decisions keyed by checkpoint number | `{ "1": { "status": "approved", ... } }` |
+
+> **Checkpoint entry format** (see [`protocols/checkpoint-gate.md`](protocols/checkpoint-gate.md)): each entry is `{ "status": "approved", "feedback": null, "decided_at": "2026-02-23T21:35:00Z" }`. Status may be `approved`, `modified`, or `aborted`.
+| `skip_all` | Whether checkpoints beyond the current one auto-approve | `false` |
+| `evaluation_due_at` | Timestamp when Phase 7 should auto-trigger | `2026-04-08T13:00:00Z` |
+| `artifacts` | Map of produced files (prd, arch, gap_report) | `{ "prd": "PRD.md", ... }` |
+
+### Quality Gates
+- **Checkpoint approvals**: Human-signed at every `gates` entry; delivery checkpoint cannot be skipped.
+- **Gap thresholds**: Teams often target `gap_score <= 10%`. Exceeding 25% suggests spec/test misalignment.
+- **Hardening limits**: Exceeding `max_hardening_cycles` triggers the continue/deliver/abort decision.
+- **Outcome KPI score**: Anything under 70/100 in OUTCOME-REPORT.md triggers a follow-up action item.
+
+### Operator Checklist
+- [ ] Confirm `.factory/` is gitignored (see `.gitignore`).
+- [ ] Keep agent prompts under 200 lines (`wc -l agents/*.md`).
+- [ ] Update `catalog.yml` version whenever SKILL or agent prompts meaningfully change.
+- [ ] Run `.github/workflows/validate.yml` locally (or via PR) before merging.
+- [ ] Archive finished runs you care about; delete stale entries with `rm -rf .factory/archive/run-*`.
+- [ ] Review [`docs/ADR.md`](docs/ADR.md) before proposing governance changes.
+
+### Run Artifacts & Locations
+| Artifact | Produced By | Stored In | Notes |
+|----------|-------------|-----------|-------|
+| `PRD.md` | Product Manager | Worktree root & archive | Trimmed to `max_prd_lines`. |
+| `ARCH.md` | Architect | Worktree root & archive | Contains diagrams + contracts. |
+| `GAP-REPORT.md` | QA Validator | Worktree root & archive | Records gap score + failure table. |
+| `FACTORY-REPORT.md` | Factory Manager | Worktree root | Delivery summary template. |
+| Sealed tests | QA Sealed | `.factory/sealed/<run-id>` | Hidden until validation; hashed. |
+| `OUTCOME-REPORT.md` | Outcome Evaluator | Worktree & archive | KPI + post-ship assessment. |
+
+### Data Retention & Cleanup
+- `.factory/runs/` should contain only active runs. Delivery/abort must delete the worktree and branch immediately.
+- `.factory/archive/` feeds Phase 7; keep what you need, prune the rest.
+- `state.json` is recreated for every run and may be deleted once the run is merged and archived.
+
+## FAQ
+1. **Does express mode skip QA?** No. QA Sealed still writes tests — it just uses the raw goal as its spec.
+2. **Can I run different models per agent?** Yes, edit `config.yml.models.*`. Dark Factory reads it on every run.
+3. **What if a task times out?** The Factory retries automatically up to `factory.max_retries`. After that it surfaces the error.
+4. **Where do sealed tests live?** `.factory/sealed/<run-id>`. They are hashed in Phase 2 and copied into the worktree only when QA Validator runs them.
+5. **How do I keep artifacts small enough?** Use the `max_prd_lines / max_artifact_lines` tunables; SKILL enforces them automatically and will re-run an agent if the cap is exceeded.
+6. **When is Phase 7 triggered automatically?** If `auto_evaluate_after_days` > 0, `dark factory status` or `resume` checks for due runs and launches the Outcome Evaluator.
+7. **Can sealed tests ever be revealed?** Only after delivery, inside archived artifacts for outcome evaluation — never to builders mid-run.
+8. **What’s the “Lights Out” codename about?** It reflects the goal: build in the dark (sealed tests) until the final delivery checkpoint flips the lights back on.
+
+## Troubleshooting
+| Symptom | Likely Cause | Fix |
+|---------|--------------|-----|
+| `fatal: worktree add` fails | Dirty git state/untracked files | Commit/stash changes, ensure `.factory/` is gitignored, rerun. |
+| QA Sealed crashes citing “unknown stack” | Goal/PRD lacked tech hints | Add a “Technical Constraints” section or mention the runtime in the goal; rerun Phase 2. |
+| GAP score stays >0 after 3 cycles | Hardening limit reached | Choose **continue-hardening** to reset the counter or **deliver-as-is** to surface outstanding failures. |
+| `state.json` missing for resume | Worktree cleaned manually | Use `dark factory status` to list available runs; if none, restart from Phase 0. |
+| Markdown lint fails in CI | Missing newline at EOF or long lines | Run `markdownlint '**/*.md' --ignore node_modules` locally. |
+| YAML validation job fails | Syntax error in `config.yml` or `catalog.yml` | Run `python -c "import yaml; yaml.safe_load(open('config.yml'))"` to pinpoint the issue. |
+| “Files referenced in catalog.yml do not exist” | Added/renamed prompt without updating catalog | Keep `SKILL.md` + agent file paths in sync with `catalog.yml`. |

+1. **Read configuration:** ALWAYS `view config.yml` first. Treat it as the single source of truth (models, timeouts, thresholds).
+2. **Determine mode:** If user said "express" OR goal length < `config.factory.express_threshold_words`, set mode=express.
+3. **Initialize state:** Create/update `config.isolation.state_file` (default `.factory/state.json`) and SQL tables.
+4. **Repo signals:** Capture a file listing (names only) for stack detection.
+
+---
+
+## Execution Guardrails (Timeouts, Retries, Artifact Limits)
+
+1. **Timeouts:** If an agent call takes longer than `config.factory.agent_timeout_sec`, retry up to `config.factory.max_retries`.
+2. **Retries:** Retries re-dispatch the same role with the same inputs plus a short failure note.
+3. **Artifact size:** If PRD or any artifact exceeds `config.safety.max_prd_lines` / `config.safety.max_artifact_lines`, summarize it before passing downstream. Preserve acceptance criteria verbatim where possible.
+4. **Verbosity:** Use `config.factory.verbosity` to decide how much progress text to print (debug/info/warn/error).

+This project is intentionally "just a skill" (Markdown + YAML). These short ADRs explain why the core design choices exist and what constraints they protect.
+
+---
+
+## ADR-0001: Sealed-envelope testing
+
+**Decision:** Generate acceptance tests from the PRD before implementation and keep them hidden from the builder.
+
+**Why:** The builder should not be able to optimize for the tests. Sealed tests measure spec coverage, not test memorization.
+
+**Consequences:**
+
+- QA Sealed must not see code.
+- Lead Engineer must not see sealed tests.
+- Hardening must use failure messages only.
+
+---
+
+## ADR-0002: Git worktree isolation
+
+**Decision:** Build in an isolated git worktree under `.factory/runs/<run-id>`.
+
+**Why:** Isolation prevents partially generated changes from contaminating the main working tree and makes "reject" safe.
+
+**Consequences:**
+
+- Delivery is a merge (approve) or teardown (reject).
+- Worktree cleanup must be reliable.
+
+---
+
+## ADR-0003: Checkpoint gates (human-in-the-loop)
+
+**Decision:** Pause after major phases using `ask_user`.
+
+**Why:** Fully autonomous codegen can drift. Checkpoints give humans a chance to correct the spec, stop unsafe work, or go fully dark (skip-all) when appropriate.
+
+**Consequences:**
+
+- Phase 6 (delivery) checkpoint cannot be skipped.
+- Checkpoints must be consistent and predictable.
+
+---
+
+## ADR-0004: Speed-stack model routing via config.yml
+
+**Decision:** Route models per role (spec writers vs validators) using `config.yml`.
+
+**Why:** Different roles have different cost/quality profiles. Config-driven routing makes this adjustable without prompt edits.
+
+**Consequences:**
+
+- Prompts must not hardcode model names.
+- The orchestrator must pass `model=<config.models.*>` on every `task()` call.
+
+---
+
+## ADR-0005: Prompt size limits (the 200-line rule)
+
+**Decision:** Keep each agent prompt under 200 lines.
+
+**Why:** Smaller prompts are easier to audit, less contradictory, and cheaper to iterate. Complexity should live in the orchestrator, not in a single agent prompt.
+
+**Consequences:**
+
+- Split responsibilities if prompts grow.
+- CI enforces the limit.

+## What "good" output looks like
+
+A healthy run includes:
+
+- A factory banner with **run ID** and **mode**
+- Checkpoints with the correct `ask_user` options
+- A sealed hash displayed after Phase 2 (Full mode)
+- A delivery report at the end

+
+<!--
+Example (filled in):
+## Goal
+Ship a cross-repo dependency auditor CLI that flags GPL dependencies.
+
+## Problem Statement
+Enterprise release managers need an automated way to detect GPL/LGPL licenses before shipping.
+
+## User Stories
+1. As a release manager, I can scan a repo and receive a license summary within 60 seconds.
+2. As a security engineer, I can export the findings to CSV for audits.
+
+## Success Criteria
+- [ ] Scan completes under 1 minute for <10k files
+- [ ] Reports list dependency, version, license, and risk rating
+
+## Scope
+### In Scope
+- CLI ingestion of package-lock.json and requirements.txt
+- Risk rules for GPL/LGPL
+
+### Out of Scope
+- Remediation PRs
+- UI dashboards
+
+## Acceptance Criteria
+### License Scan
+- Given a repo with package-lock.json, when I run `df-lic scan`, then a summary table is printed with risk tiers.
+- Given GPLv3 dependency, when scan finishes, then exit code is 2 with remediation guidance.
+
+## Technical Constraints
+- Implemented in TypeScript
+- Must run on macOS and Linux
+
+## Strategic Context
+### Objective
+Reduce compliance review time by 40%.
+
+### Key Results
+1. Flag 100% of GPL dependencies pre-release.
+2. Generate CSV reports with <5% false positives.
+
+### KPIs
+| KPI | Baseline | Target | Measurement Method |
+| License review time | 5 days | 3 days | PMO tracker |
+
+## Stakeholder Map
+| Stakeholder | Interest | Impact Level |
+| Release Manager | Risk reduction | High |

+## [0.3.0] - 2026-02-24
+
+### Added
+
+- **Auto-Evolution Protocol (L6):** Factory autonomously improves its own agent prompts every 5 completed runs. Generates 3 mutations, benchmarks each via express builds with sealed testing, selects winner by gap score, applies with human approval (configurable). Full rollback support.
+- **New SQL Table:** `prompt_mutations` tracks every mutation attempt, acceptance, and rollback.
+- **New Commands:** `dark factory auto-evolve` (manual trigger), `dark factory rollback <agent>` (instant revert).
+- **New Config Section:** `auto_evolve` with 8 tunables (frequency, variants, safety thresholds, approval gate).
+- **Safety Invariants:** One-axis mutations, frontmatter preservation, 200-line enforcement, I/O contract locking, mandatory backup before mutate.
+
+## [0.2.0] - 2026-02-24
+
+### Added
+
+- **Cost Tracking:** Per-phase cost estimation with model pricing reference. Delivery report includes total run cost summary.
+- **Multi-Model QA Sealed:** Optional secondary model for sealed test generation (`config.diversity.qa_sealed_secondary`). Produces more diverse test coverage.
+- **Fitness Scoring:** Track gap scores, cost, and speed per run. `dark factory fitness` surfaces model routing recommendations based on historical performance.
+- **Express Micro-PRD:** Express mode generates a structured 5–15 line micro-PRD before dispatching agents, improving test and build quality for short goals.
+- **Prompt Evolution Tracking:** Hash agent prompts per run, correlate with gap scores. `dark factory evolve` identifies best-performing prompt versions.
+- **New SQL Tables:** `factory_fitness` for run quality tracking, `prompt_versions` for prompt-gap correlation.
+- **New Commands:** `dark factory fitness` and `dark factory evolve`.
+- **Config Sections:** `cost_tracking`, `diversity`, `fitness`, `express` added to `config.yml`.

+
+## Fitness Scoring
+
+When `config.fitness.enabled` is true, the factory tracks run quality over time.
+
+**Fitness Score Formula:**
+```
+fitness = (quality × 0.50) + (cost_efficiency × 0.25) + (speed × 0.25)
+
+quality        = 1.0 - (gap_score / 100)
+cost_efficiency = 1.0 - min(total_cost_usd / 5.0, 1.0)
+speed          = 1.0 - min(total_duration_sec / 1800, 1.0)
+```
+
+**`dark factory fitness`** — Display fitness history and model routing recommendations:
+
+1. Query fitness data:
+   ```sql
+   SELECT config_hash, AVG(fitness_score) as avg_fitness, AVG(gap_score) as avg_gap,
+          AVG(total_cost_usd) as avg_cost, COUNT(*) as runs, models_used
+   FROM factory_fitness GROUP BY config_hash ORDER BY avg_fitness DESC;
+   ```
+2. If runs ≥ `config.fitness.min_runs_for_confidence` for any config, compare fitness scores.
+3. If the fitness delta between best and current config exceeds `config.fitness.suggestion_threshold`:
+   ```
+   🏭 FITNESS INSIGHT: Config <hash_A> scores {X} higher than current.
+      Models: <models_A> vs <models_current>
+      Avg gap score: <gap_A>% vs <gap_current>%
+      Recommendation: Update config.yml models to match config <hash_A>.
+   ```
+4. Print fitness trend: `🏭 Factory fitness: <score>/1.0 (↑/↓ <delta> from last 5 runs)`
+
+---
+
+## Prompt Evolution
+
+The factory tracks which prompt versions produce the best gap scores. This enables data-driven prompt improvement.
+
+**`dark factory evolve`** — Surface best-performing prompt versions:
+
+1. Query prompt performance:
+   ```sql
+   SELECT agent_name, prompt_hash, AVG(gap_score) as avg_gap, COUNT(*) as runs
+   FROM prompt_versions
+   GROUP BY agent_name, prompt_hash
+   HAVING runs >= 3
+   ORDER BY agent_name, avg_gap ASC;
+   ```
+2. For each agent, compare current prompt hash to best-performing hash.
+3. If current prompt is NOT the best performer and delta > 5%:
+   ```
+   🏭 PROMPT EVOLUTION: Agent <name> — current prompt scores <X>% avg gap.
+      Best historical prompt (hash <hash>) scored <Y>% avg gap across <N> runs.
+      Action: Review git history for prompt <hash> and consider reverting or merging improvements.
+   ```
+4. Suggest a Prompt Genome Protocol cycle:
+   - Baseline: current prompt's avg gap score
+   - Mutate: create 3 variants targeting the gap areas
+   - Evaluate: run all variants through express mode builds
+   - Select: keep the winner based on gap score
+
+---
+
+## Auto-Evolution Protocol
+
+When `config.auto_evolve.enabled` is true, the factory autonomously improves its own agent prompts every `config.auto_evolve.every_n_runs` completed runs (default: 5). This is what makes Dark Factory L6 — it doesn't just self-correct, it self-improves.
+
+**Trigger:** Automatically after Phase 6 delivery when `completed_runs % every_n_runs == 0`.
+
+**`dark factory auto-evolve`** — Manually trigger an evolution cycle.
+
+### Protocol Steps
+
+**Step 1 — Identify Weakest Agent**
+
+Find the agent whose prompts correlate with the highest gap scores:
+
+```sql
+SELECT agent_name, AVG(gap_score) as avg_gap, COUNT(*) as runs,
+       prompt_hash as current_hash
+FROM prompt_versions
+WHERE recorded_at >= datetime('now', '-30 days')
+GROUP BY agent_name
+ORDER BY avg_gap DESC
+LIMIT 1;
+```
+
+Only evolve `config.auto_evolve.max_mutations_per_agent` agent(s) per cycle (default: 1).
+
+**Step 2 — Backup Current Prompt**
+
+```bash
+cp agents/<agent>.md .factory/archive/prompts/<agent>-<hash>-<date>.md
+```
+
+Keep the last `config.auto_evolve.keep_versions` backups. Delete older ones.
+
+**Step 3 — Analyze Failure Patterns**
+
+Query the most common sealed test failure patterns for this agent's runs:
+
+```sql
+SELECT pv.run_id, pv.gap_score, fr.goal
+FROM prompt_versions pv
+JOIN factory_runs fr ON pv.run_id = fr.run_id
+WHERE pv.agent_name = '<agent>' AND pv.gap_score > 0
+ORDER BY pv.gap_score DESC
+LIMIT 5;
+```
+
+Read the corresponding GAP-REPORT.md files from the archive to identify recurring failure categories (edge cases, error handling, security, etc.).
+
+**Step 4 — Generate Mutations**
+
+Dispatch a mutation generator (runs `config.auto_evolve.variants` variants, default: 3):
+
+```
+task(agent_type="general-purpose", model="<config.models.architect>", description="Prompt mutation", prompt="
+You are a Prompt Evolution Engineer for the Dark Factory.
+
+## Mission: Generate <N> improved variants of an agent prompt, each targeting a specific weakness.
+
+## Current Prompt:
+<contents of agents/<agent>.md>
+
+## Observed Weaknesses (from gap reports):
+<failure pattern summary from Step 3>
+
+## Rules:
+1. Each variant changes ONE axis only (specificity, structure, constraints, examples, or tone).
+2. Keep under 200 lines.
+3. Preserve the frontmatter (name, description, tools) exactly.
+4. Preserve the core I/O contract (same inputs, same outputs).
+5. Output each variant as a clearly labeled code block: VARIANT_1, VARIANT_2, VARIANT_3.
+6. After each variant, write one sentence explaining WHAT you changed and WHY.
+")
+```
+
+Parse the response to extract each variant.
+
+**Step 5 — Benchmark Each Variant**
+
+For each variant (plus the current prompt as control):
+
+1. Write the variant to `agents/<agent>.md` (temporarily).
+2. Run an express-mode factory build using `config.auto_evolve.test_goal`:
+   ```
+   dark factory express — <config.auto_evolve.test_goal>
+   ```
+3. Record the gap score.
+4. Restore the original prompt before testing the next variant.
+
+Results table:
+
+```
+🏭 EVOLUTION BENCHMARKS — Agent: <agent>
+┌──────────┬──────────┬──────────────────────────────┐
+│ Variant  │ Gap Score│ Mutation Description          │
+├──────────┼──────────┼──────────────────────────────┤
+│ Control  │   12.5%  │ (current prompt)             │

+│ V3       │   14.2%  │ Changed tone to more paranoid│
+└──────────┴──────────┴──────────────────────────────┘
+```
+
+**Step 6 — Select Winner**
+
+- Winner = variant with lowest gap score.
+- Winner must beat the control by at least `config.auto_evolve.min_improvement_pct` (default: 3%).
+- If no variant beats the threshold: `🏭 No improvement found. Keeping current prompt.`
+- If a winner is found:
+
+```sql
+INSERT INTO prompt_mutations (agent_name, mutation_type, parent_hash, mutant_hash,
+  gap_score_before, gap_score_after, accepted, backup_path)
+VALUES ('<agent>', '<axis_changed>', '<old_hash>', '<new_hash>',
+  <control_gap>, <winner_gap>, TRUE, '<backup_path>');
+```
+
+**Step 7 — Apply or Approve**
+
+If `config.auto_evolve.require_approval` is true (default):
+
+```
+🏭 EVOLUTION CANDIDATE — Agent: <agent>
+   Gap score: <control>% → <winner>% (Δ -<improvement>%)
+   Mutation: <what_changed>
+   Backup: <backup_path>
+```
+
+→ `ask_user`: **apply** / **reject** / **diff** (show the changes)
+
+If `require_approval` is false: auto-apply the winner.
+
+On **apply**:
+1. Write the winning variant to `agents/<agent>.md`.
+2. Update `prompt_mutations` with `applied_at = datetime('now')`.
+3. Print: `🏭 Evolution applied. Agent <agent> upgraded. Gap score: <old>% → <new>% 🧬`
+
+On **reject**:
+1. Keep the original prompt.
+2. Update `prompt_mutations` with `accepted = FALSE`.
+3. Print: `🏭 Evolution rejected. Agent <agent> unchanged.`
+
+**Step 8 — Rollback Command**
+
+**`dark factory rollback <agent>`** — Revert an agent to its previous prompt version:
+
+1. Query the most recent applied mutation:
+   ```sql
+   SELECT backup_path, parent_hash FROM prompt_mutations
+   WHERE agent_name = '<agent>' AND accepted = TRUE AND rolled_back_at IS NULL
+   ORDER BY applied_at DESC LIMIT 1;
+   ```
+2. Copy backup to `agents/<agent>.md`.
+3. Update: `UPDATE prompt_mutations SET rolled_back_at = datetime('now') WHERE ...`
+4. Print: `🏭 Rollback complete. Agent <agent> restored to <parent_hash>.`
+
+### Safety Invariants
+
+1. **One axis per mutation.** Never change structure AND content simultaneously.
+2. **Frontmatter is sacred.** Tools, name, and description never change during evolution.
+3. **200-line limit enforced.** Any variant exceeding 200 lines is discarded.
+4. **I/O contracts preserved.** Input and Output sections must remain semantically identical.
+5. **Backup before mutate.** Every evolution cycle creates a recoverable backup.
+6. **Rollback is instant.** `dark factory rollback <agent>` always works.
+7. **Sealed envelope still applies.** Evolution benchmarks use the same sealed testing protocol.
+8. **No evolution during active runs.** Auto-evolve only triggers after Phase 6 completes.

Subject: [PATCH 5/5] fix(ci): remove CodeQL python scan, relax markdownlint
 for pure-Markdown repo

- Delete codeql.yml: repo has no runtime code (ADR-005), CodeQL python
  scan fails with "no source code seen during build"
- Disable MD022/024/025/031/032/036/040/058/060 in validate.yml:
  agent prompts use multi-H1 structure, templates use compact tables,
  CHANGELOG repeats section headings by design
