It enables existing legacy, single-package, or foreign repositories to be analyzed, diagnosed, and non-destructively adopted into the standardized multi-package ecosystem hierarchy (`~/src/PLAN.md` §1.A, Phase 4). + +## 1. Architectural Overview + +Per Note [Non-Destructive Skeleton Overlay] [ref:note-nondestructive-retrofit], retrofitting operations must **never** delete, overwrite, or mutate domain logic source files (`src/`, `app/`, `lib/`, `test/`). The engine executes through a two-phase architecture: + +1. **Milestone 4.1: Diagnostic Repository Inspector:** Conducts rigorous, read-only static analysis across six dimensions (languages, build manifests, test suites, documentation gaps, Git governance, verification gates) and computes quantitative readiness scores. +2. **Milestone 4.2: Non-Destructive Skeleton Overlay:** Computes an explicit `OverlayPlan` categorizing missing standardized assets as `ActionCreate` and pre-existing files as `ActionPreserve`. In live mode, materializes missing documentation, agent rules, Git hooks, and verification runners (`bin/*-verify`) with executable bits, and configures Git governance without touching domain code. +3. **Milestone 4.3: Progressive Quality Gate Realization:** Evaluates target repositories across four progressive compliance levels (L0–L3) and computes prioritized incremental remediation plans per Note [Progressive Quality Gate Realization and Incremental Compliance Levels] [ref:note-progressive-quality-gates]: + - **Level 0 (Foundation):** Scaffolding, documentation skeletons, Git hooks, and turnkey verification harnesses installed. + - **Level 1 (Structural Integrity):** Tagref cross-references certified with zero dangling pointers; Markdown link & anchor integrity verified. + - **Level 2 (Compiler Discipline):** Haskell builds compile cleanly under `-Wall -Wcompat -Wredundant-constraints` with zero warnings. + - **Level 3 (Static Analysis Purity):** HLint reports zero hints under `.hlint.yaml`; in-code comment density satisfies the 25.0% threshold (50.0%+ target on `src/`); full test suites pass cleanly. + +``` +Arbitrary Target Workspace + │ + ├─► [Language Detection] ──► Primary Language, Polyglot breakdown, Source File Counts + ├─► [Build System Detection] ──► Cabal (Single/Multi), Stack, Cargo, CMake, Make, Meson, Poetry + ├─► [Test Infrastructure] ──► Test directories, Suites declared, Frameworks (Hspec, Tasty, Cargo) + ├─► [DOC_STRATEGY.md Gaps] ──► Orientation, Corpus Inventory, Architecture Notes, Operational Loop + ├─► [Git Governance Status] ──► .githooks, commit-msg (RFC 2822 Assisted-by:), pre-commit, .gitmessage + └─► [Verification Harnesses] ──► Turnkey verify runner, Tagref gate, Linkcheck gate, CLOC harness + │ + ▼ + DiagnosticReport & Retrofit Readiness Score (0.0% – 100.0%) + │ + ▼ + Non-Destructive Overlay Plan (Milestone 4.2) + │ + ├─► [ActionPreserve] ──► Existing domain code (src/, app/, lib/) left 100% untouched + ├─► [ActionCreate] ──► Missing docs, .agents/rules, .githooks, and bin/*-verify + └─► [GitGovernanceAction] ──► core.hooksPath = .githooks, commit.template = .gitmessage + │ + ▼ + Progressive Quality Gate Realization (Milestone 4.3) + │ + ├─► Level 0: Foundation (Harnesses, Scaffolding, Documentation) + ├─► Level 1: Structural Integrity (Tagref zero dangling, Linkcheck clean) + ├─► Level 2: Compiler Discipline (-Wall clean build, zero warnings) + └─► Level 3: Static Analysis Purity (Zero HLint hints, CLOC density, Tests pass) +``` + +## 2. Six Diagnostic Dimensions & Overlay Categories + +The diagnostic and overlay pipeline covers six orthogonal dimensions: + +1. **Language Stacks:** Detects primary and secondary languages (Haskell, Rust, C/C++, Python, Shell, etc.), measuring file counts and distribution percentages. +2. **Build Systems & Layout:** Identifies build manifests (`cabal.project`, `*.cabal`, `stack.yaml`, `Cargo.toml`, `CMakeLists.txt`, `Makefile`, `pyproject.toml`) and classifies workspace topology (`SinglePackage`, `MultiPackage`, `Polyglot`, `Unstructured`). +3. **Test Infrastructure:** Discovers test directories (`test/`, `tests/`), declared test suites, and testing frameworks (Hspec, Tasty, QuickCheck, Cargo test, Pytest). +4. **Documentation Gaps:** Cross-references repository assets against `DOC_STRATEGY.md` requirements (`README.md`, `docs/INDEX.md`, `docs/notes/*_DESIGN.md`, `PLAN.md`, `STATE.md`, `AGENTS.md`, `CLAUDE.md`, `.agents/rules/`). +5. **Git Governance & Attribution:** Audits and configures `.git`, `core.hooksPath`, `commit-msg` trailer enforcement (verifying Sarutahiko RFC 2822 `Assisted-by:` validation), `pre-commit`, and `.gitmessage` template configuration. +6. **Physical Verification Gates:** Evaluates and installs turnkey verification scripts (`./bin/*-verify`), Tagref cross-reference configuration, Markdown linkcheck harnesses, and comment density audit scripts. + +## 3.
