What it measures: How much of the code is actually exercised by tests.

Method: Coverage from coverlet runs or committed reports (Cobertura/OpenCover/lcov), computed per-file with structured exclusions for generated, trivial, and glue code. When the suite can't be built/run in-image AND no report is committed, coverage is reported NOT-MEASURED (excluded from the score) with the precondition to make it measurable — never a LoC-ratio proxy folded in as if measured.

What it measures: Whether any secrets (keys, tokens, passwords) have leaked into the code.

Method: In-process native secret scanner (entropy plus signature patterns) across all tracked files; no external tool. A clean result is a measured 10, not no-data zero. Deterministic.

What it measures: Whether knowledge is concentrated in too few people (the "bus factor").

Method: Living knowledge per author via time-decayed commit attribution (6-month half-life, focus weighting) across largest source files. Deterministic, avoids blame's mechanical-refactor false positives.

Maturity: Documented → Verified → Prevented · effective 8.4 / 10 · rule-coverage 100% · ceiling Documented

What it measures: Real static-analysis (SAST) findings — likely security bugs in the code, any language.

Method: Polyglot static analysis via semgrep across the repo using the pinned, image-baked p/security-audit + p/owasp-top-ten rulesets (no scan-time registry fetch); severity rules (ERROR/WARNING/INFO) map to a full-band severity-weighted score. Exhaustive, deterministic; degrades on parse failure.

Coverage: semgrep pattern rules over all files — exhaustive for the rule set, blind to classes of bug without a rule (clean = no rule matched).

Maturity: Documented → Verified → Prevented · effective 2.1 / 10 · rule-coverage 100% · ceiling Documented

Detailed fixes: d34_recommendation.md.

What it measures: Whether files that change together actually belong together — pairs that repeatedly co-change in git history despite having no explicit code dependency, surfacing the hidden/logical coupling (and boundaries in the wrong place) a static scan can't see.

Method: Pairwise co-occurrence over the per-commit file sets in git history (production source only — tests and generated dropped): Degree-of-Coupling = shared ÷ min individual revisions, reported above noise floors (each file ≥10 revisions, ≥5 shared commits, ≥50% strength); sweeping commits excluded. Deterministic over fixed history.

Coverage: Population: PRODUCTION source files only — test and generated files are dropped before pairing, so a class co-changing with its own test (trivially ~100%) can't drown the real production↔production coupling. Pairs ranked by Degree-of-Coupling; coupling through a build step, config, or non-source file isn't seen.

What it measures: Whether dependencies have known published vulnerabilities (CVEs) per the OSV database — read natively from whatever lockfile the repository ships (Cargo, npm, Go, Python, Maven, RubyGems, …). D33 and D30 add ecosystem-specific scanners on top for npm and .NET.

Method: Multi-ecosystem dependency-CVE scan via osv-scanner --recursive (queries the osv.dev database + parses lockfiles natively across ecosystems: npm package-lock/yarn/pnpm/bun, Go go.mod, Rust Cargo.lock, Maven/Gradle pom.xml/gradle.lockfile, PyPI requirements.txt/poetry.lock/Pipfile.lock, Composer composer.lock, RubyGems Gemfile.lock, Hex mix.lock, pub pubspec.lock, Swift Package.resolved); severity tally (Critical/High/Medium/Low) to 0-10 tight normalizer (8.0). NotApplicable only when the repo declares no supported non-.NET dependency lockfile (a NuGet-only repo stays NotApplicable — .NET CVEs are D30's domain); coverage needs a resolved lockfile. Additive to D33 (trivy fs); exhaustive + deterministic, DB kept fresh.

Other · Architecture — Whether read (query) handlers stay side-effect-free — a query that writes persistent state or raises events breaks CQS and makes reads unsafe to retry, cache, or route to a read replica.

Method: Roslyn scan: CQRS handlers classified query-vs-command by interface (IQueryHandler/ICommandHandler/IRequestHandler<TQuery,TResult>) and name convention (*Query/Get*/Find* vs *Command); each query handler's body checked for persistent-state writes (SaveChanges/repository Add-Update) or event publishes by resolved invocation. Deterministic, type-level, exhaustive over the detected handlers.

Coverage: Population: CQRS handlers identified by IQueryHandler/ICommandHandler/IRequestHandler interface + *Query/Get*/Find*/*Command NAME convention; query purity then checked exhaustively within that set — a query handler using neither convention is invisible, and mutation is a resolved persistence/publish CALL, not full dataflow.

• `PostgresRepoTagRepo.list_tags_with_meta` is a read-named query yet it performs a durable write on the read path (a persist to a store/repository). A query must stay side-effect-free so reads are safe to retry, cache, and route to a read replica; move the write into a command. — repo_tag_repo.rs:385
• `PostgresRepoTagRepo.list_tags_with_meta_by_values` is a read-named query yet it performs a durable write on the read path (a persist to a store/repository). A query must stay side-effect-free so reads are safe to retry, cache, and route to a read replica; move the write into a command. — repo_tag_repo.rs:476
• `RepoQueryHandler.list_with_tags` is a read-named query yet it performs a durable write on the read path (a persist to a store/repository). A query must stay side-effect-free so reads are safe to retry, cache, and route to a read replica; move the write into a command. — query.rs:166
• `RepoQueryHandler.list_ranked_with_tags` is a read-named query yet it performs a durable write on the read path (a persist to a store/repository). A query must stay side-effect-free so reads are safe to retry, cache, and route to a read replica; move the write into a command. — query.rs:293
• `RepoQueryHandler.list_by_label_with_tags` is a read-named query yet it performs a durable write on the read path (a persist to a store/repository). A query must stay side-effect-free so reads are safe to retry, cache, and route to a read replica; move the write into a command. — query.rs:315

What to do

• Keep query handlers read-only — move the writes/event-publishes into a command handler so reads stay safe to retry, cache, and route to a read replica.

Other · Domain Modelling — Whether domain identifiers are strongly typed (a newtype wrapper) rather than raw primitives — consistency once an idiom exists.

Method: Roslyn (DDD-gated): strongly-typed id adoption on domain entities/events; raw Guid/int/string ids counted versus wrapped types. Deterministic, adoption percentage.

Coverage: Population: id-like members by *Id/*Key NAME suffix; strongly-typed-ID shape then checked semantically — non-suffixed identifiers are not seen.

Other · Domain Modelling — Whether domain entities own their behaviour (invariant-enforcing commands) rather than being data-only structs driven by a foreign service.

Method: Roslyn (DDD-gated): entity method BODIES classified mutator-vs-query — only methods that mutate the entity's own declared state count as invariant-protecting behaviour, so a getter/passthrough doesn't rescue an anemic class. Deterministic, exhaustive over domain-layer entities.

Coverage: Population: entities by name/base convention; rich-vs-anemic judged by classifying each method body mutator-vs-query — logic-bearing domain types outside the convention are invisible.

Other · Domain Modelling — Whether a domain type's identity-bearing field stays immutable — a `pub` mutable field under a hand-rolled Hash/PartialEq breaks the value-identity invariant.

Method: Roslyn (DDD-gated): public setters on entities detected; score softened when Marten/EF rehydration frameworks present. Deterministic, framework-aware.

Coverage: Population: entities by convention; encapsulation (setter shape) checked exhaustively within the set.

Other · Domain Modelling — Whether the domain layer stays free of infrastructure dependencies — a domain aggregate fused to a persistence ORM (diesel/sea-orm/sqlx) on its own declaration (active-record) couples the domain to infrastructure. The clean-architecture dependency rule.

Method: Roslyn (DDD-gated): domain-layer types scanned for infrastructure usage in member SIGNATURES and inside method/accessor BODIES — resolved calls and object-creations into EF/Marten/HTTP/Mongo/Redis/message-bus types (not just a namespace allowlist). Deterministic, symbol-resolved, exhaustive over domain-layer bodies, DDD-native.

Coverage: Domain layer identified by NAMESPACE heuristic; infrastructure then resolved by symbol in member SIGNATURES and method/accessor BODIES — rename the layer and the check evaporates.

Other · Event-Driven — Whether state changes and message publishes are atomic (a transactional outbox) rather than a crash-unsafe dual write.

Method: Roslyn semantic scan (event-driven gated): event-handler methods scanned for DB-save plus bus-publish without a transactional outbox reference. Deterministic, semantic-resolved.

• `RepoQueryHandler.list_with_tags` performs two independent DURABLE writes — a durable state write (`current_repo_ids.insert`, :229) and a second independent durable store write — in one command path with no shared transaction or outbox. A crash between the two leaves the stores diverged (one write committed, the other lost) or emits a phantom record. Wrap both in one transaction, or record the second write in the same store and dispatch it afterwards (a transactional outbox). — query.rs:166

What to do

• Adopt the transactional outbox pattern so DB writes and message publishes commit atomically — no lost or phantom events on a crash.

Maturity · Maturity — Whether the repo and its projects have a README, and whether it's substantive and current.

Method: Filesystem scan: README presence, word count, and headings for depth; git history for staleness. Exhaustive across root and project dirs, deterministic.

What to do

• Add a build/run (quick start) section to the root README — the first thing a newcomer needs.
• Add a 'Testing' section to the root README — how to run the test suite.
• Add a README to the 6 of 6 project(s) that lack one — worth up to 2 pts.

Maturity · Maturity — Whether key decisions (ADRs) and the high-level shape (C4/diagrams) are written down.

Method: Filesystem scan: ADR folder/naming conventions or content, plus Mermaid/PlantUML/C4/architecture.md discovery. Exhaustive, deterministic.

• No Architecture Decision Records found — decisions aren't captured for future maintainers.

What to do

• Start an ADR log (docs/adr/) recording significant decisions and their rationale.

Maturity · Maturity — Whether the repo is organised deliberately — src/test separation and consistent project naming.

Method: Filesystem scan: src/test folder separation and namespace-prefix consistency (majority RootNamespace agreement). Exhaustive across projects, deterministic.

• No test surface was found — a `#[cfg(test)] mod tests` block beside the code it tests (with `tests/` reserved for integration tests) is where this ecosystem separates tests, and none is present.

What to do

• Add `#[cfg(test)] mod tests` blocks beside the code they cover — the attribute keeps them out of the release build, a stronger separation than a folder — reserve `tests/` for black-box integration tests, and run `cargo test` in CI.

Maturity · Maturity — Whether the README actually describes the code that exists (LLM-judged, advisory).

Method: Judged by language model at low temperature: README accuracy versus actual projects, within a disclosed tolerance. Advisory, not a measured number.

• README claims a curated GitHub project list but the evidence shows no such list (only crates/ directories)
• README claims a trend-focused UI layer but there is no corresponding UI in the directory tree

What to do

• Reconcile the README with reality: README claims a curated GitHub project list but the evidence shows no such list (only crates/ directories); README claims a trend-focused UI layer but there is no corresponding UI in the directory tree.

Readiness · Readiness — Whether an automated pipeline builds and tests every change.

Method: Filesystem scan: CI workflow files (.github/workflows, .gitlab-ci.yml, etc.) for build and test stages. Exhaustive, deterministic.

• A CI pipeline exists and the word "test" appears, but no explicit test-runner invocation (your stack's test command, or a test job) was matched — the gate may be running tests, or "test" may be incidental (a path, "latest", a reporter). Make the test step explicit so the gate is unambiguous.
• A CI pipeline exists but no build/compile invocation (a build step for your stack — dotnet build, npm run build, go build, mvn package, cargo build, …) was matched — changes may merge without being compiled.

What to do

• Run the test suite in CI via an explicit runner step (`cargo test` for the toolchain this pipeline already uses) and gate merges on it.
• Add an explicit build/compile step to your CI pipeline (whatever your stack uses — e.g. dotnet build, npm run build, go build, mvn package, swift build/xcodebuild) so every change is compiled before merge.

Readiness · Readiness — Whether SAST, secret/dependency scanning and performance benchmarking are wired in (presence, not runtime).

Method: Filesystem scan: SAST configuration, dependency-update automation, secret scanning, and a benchmark harness or benchmark step — in this repository's own ecosystem. Exhaustive, deterministic.

What to do

• Enable Dependabot/Renovate or a dependency-review gate.
• Add gitleaks/trufflehog in CI to block PRs that introduce committed secrets.

Readiness · Readiness — Whether releases are automated and safely reversible (probes, rolling updates, approval gates) — from manifests/pipeline files, not the live environment.

Method: Filesystem scan: deployment manifests/IaC (K8s YAML, Helm, Terraform) for rolling updates, probes, approval gates, migration hooks. Exhaustive, deterministic.

What to do

• Nothing pauses a release for a human: publish as a draft release (or gate the release job on a protected tag/manual dispatch) so a bad build can be stopped before users can download it.

Readiness · Readiness — Whether releases are traceable — a maintained changelog and explicit version stamping.

Method: Filesystem scan: changelog file presence and version tags in csproj or git tags. Exhaustive, deterministic.

• No CHANGELOG/HISTORY/RELEASES file — what shipped when isn't easy to reconstruct for support or audit. (Versioning/tagging makes releases traceable, but a changelog records the what.)

What to do

• Keep a changelog (e.g. Keep-a-Changelog) recording what shipped in each release.

React / JS · Code Health — How much of the frontend is typed TypeScript vs untyped JavaScript.

Method: Frontend file inventory: the share of typed TypeScript vs untyped JavaScript across the source tree. Deterministic, exhaustive over frontend files.

• 0 typed · 5 plain JS

What to do

• Migrate the remaining .js/.jsx files to TypeScript.

React / JS · Code Health — Copy-pasted token-identical blocks across the frontend (the D4 clone algorithm over JS/TS tokens, D-386).

Method: Copy-pasted token-identical blocks across the frontend (the D4 clone algorithm run over JS/TS tokens). Deterministic.

React / JS · Code Health — Per-function cyclomatic/cognitive complexity from the token-level function scanner (D-386) — real branching, not a regex heuristic.

Method: Per-function cyclomatic/cognitive complexity from a token-level function scanner (real branching, not a regex heuristic), computed over every frontend function. Deterministic.

• Branch-heavy code is where defects cluster — extract decisions into smaller functions. (×2) — dom_bridge.js:109, chart_bridge.js:60

What to do

• Break down the listed branch-heavy functions; aim P95 cyclomatic ≤ 5.

React / JS · Code Health — How many components/modules exceed the large-file threshold.

Method: Components/modules exceeding the large-file threshold, counted exhaustively across the frontend source tree. Deterministic.

React / JS · Readiness — Static test reachability (D-386): the share of production files reachable from any test via the import graph — measured without running anything.

Method: Static test reachability: the share of production files reachable from any test via the import graph — measured without running anything. Deterministic.

• No test imports this module directly or transitively. If it is a CLI, check whether a suite runs it as a child process; otherwise it has no test reaching it. (×5) — dom_bridge.js, chart_bridge.js, theme_bridge.js, …

What to do

• Add tests that import the unreached modules (directly or through their public entry).

React / JS · Code Health — Files unreachable from every application/tooling/test entry point, and exports nothing imports (module-graph reachability, D-386).

Method: Dead code: files unreachable from every application/tooling/test entry point plus exports nothing imports, via module-graph reachability. Deterministic, exhaustive over the import graph.

• 5 file(s) (~348 LoC) were excluded from dead-code analysis — declare main/module/exports or a conventional entry (src/index.*, an index.html script) so reachability can see this package.

React / JS · Readiness — npm dependency truthfulness (D-386): unused dependencies, imports not declared anywhere, and type-/test-only packages shipped as production deps.

Method: npm dependency truthfulness: unused dependencies, imports declared nowhere, and type-/test-only packages shipped as production deps — from the manifest + import graph. Deterministic.

React / JS · Architecture — Import cycles in the module graph (D-386) — files that can only be understood and changed together.

Method: Import cycles in the module graph, detected exhaustively over JS/TS imports (the same cycle detection as the .NET coupling dimension). Deterministic.
