45/112dimensions across the health lenses1513809 LoC — wide & deep
Executive summary
Read through the Production lens — the standard calibration. *Green* means good enough to run in production. The score is absolute and comparable across repos.
apache/hadoop carries serious gaps (44%). Several issues below can materially affect correctness, security, or the cost of changing it — and propagate to everything that depends on it.
It is strongest in Domain Modelling (100%) — the domain model is expressive and well-guarded.
Most urgent: a critical security exposure was detected (see the Security & Compliance lens). Treat it as a priority regardless of the overall grade.
The area that most needs attention is Accessibility (35%) — it raises ongoing delivery and operational cost. Readiness (46%) is the next concern — releases are harder to depend on — versioning, release notes and dependency hygiene are thin, so consumers can't easily tell what changed or trust an upgrade.
Leadership focus, highest impact first: Make custom controls keyboard-operable (role + tabindex + key handler) (Keyboard semantics); Declare <html lang>, a document <title> and a <main> landmark,… (Page structure); accessibility in the toolchain (A11y enforcement).
For scale: Very large (~1,513,809 production lines); rebuilding it from scratch would take roughly ~22.0 person-years (~13–42 engineers). Approximate, ±~30%.
It builds on a genuinely strong Domain Modelling foundation (100%); the priorities above are the highest-leverage way to bring the rest up to that level.
How the score is built — each lens's share of the headlineWidth is the lens's weight in the worst-heaviest fold (the weakest area pulls hardest); colour is that lens's own band. A lens fixes the score in proportion to its width.
676 finding(s) are new versus the previous scan (2026-07-20) — surfaced by this scheduled scan itself, no pull request required. Showing the first 100; the full set is in the report.
A full-fidelity diff against the previous run's complete recorded findings — line-move tolerant: a finding that only shifted line counts as unchanged, only genuinely new titles/files surface here.

Dead frontend code
~1701 LoC unreachable (18 file(s)) — that slice of this estimate buys code with zero runtime value; deleting it is the cheapest win in this report (the R7 card lists every file)
This codebase represents roughly ~22.0 person-years of build effort (about ~€3,200,000 to rebuild). Its weakest lens is Accessibility at 35% — the part of that asset most exposed by the findings below.
How we model this: boilerplate at a scaffolding rate + logic × domain High (×1.4) — CQRS, domain model × a 0.7× quality factor, at €60–95/h; indicative, ±~30% · size measured directly from source · effort from total production LoC as straight-line logic (the tier split is a C#-only syntax walk), a conservative lower bound. Indicative only — most sensitive to the hourly rate and the domain tier (both tunable in config).
Top priorities
The highest-leverage moves; the full ranked list is in the Roadmap below.
1
Make custom controls keyboard-operable (role + tabindex + key handler), drop positive tabindex, and give anchors a real href.
Value concentrated against a weak lens · High · Value at risk
This is a Very large asset (~22.0 person-years to rebuild), and its weakest lens is Accessibility at 35%. The operational and business risk on an asset this size concentrates there — that's where remediation buys the most protection.
→ Direct remediation budget at Accessibility first — highest risk-reduction per euro on an asset this size.
Highest-leverage move · Medium · Leverage
Of everything flagged, the best return on effort is: Make custom controls keyboard-operable (role + tabindex + key handler), drop positive tabindex, and give anchors a real href. The rest can wait behind it.
Evidence: priority ranking: top of 5 ranked by impact/effort
→ Make custom controls keyboard-operable (role + tabindex + key handler), drop positive tabindex, and give anchors a real href.
A velocity tax on every change · Medium · Economics
The code-quality signals (complexity, duplication, cohesion) average 6.7/10, which acts as a tax on every change in the weaker areas: modifications there plausibly cost on the order of 3–7% more than in clean code, and the tax compounds as the codebase grows. (A modelled estimate, not a measured fact.)
Evidence: D1/D2 complexity, D4 duplication, D6 cohesion: averaging 6.7/10 across the code-quality signals
→ Pay it down where churn is highest — the hotspots — not everywhere; that's where the tax is actually paid.

Roadmap
First, ensure all interactive elements and controls are fully keyboard-operable and properly linked. Next, establish a solid page structure by adding essential landmarks, titles, and heading hierarchy. Then, implement automated accessibility enforcement in the toolchain to prevent future regressions. Finally, provide text alternatives for media and ensure all form controls have programmatic labels.
Ranked by impact ÷ effort. "Helps" is the estimated gain on the 0–100 health score.

Dimension
Make custom controls keyboard-operable (role + tabindex + key handler), drop positive tabindex, and give anchors a real href.
Add a text alternative — alt on images (alt="" for purely decorative ones), a title or aria-label on meaningful svg, an aria-label or inner fallback content on canvas, and a captions <track> on video.
Keep a visible focus style (don't remove the outline without a replacement), guard animation with prefers-reduced-motion, and raise low-contrast colour pairs to at least 4.5:1.
Watchdog is a deep, periodic assessment — run each sprint, monthly, or quarterly, taking the time to go wider and deeper than a quick check and surfacing in one coherent report what you'd otherwise piece together from a dozen separate tools. It scores deterministically: the same commit yields the same score, every run. 44 of 45 evaluated dimensions are computed purely by tools and static analysis (confidence 1.0); 1 documentation/naming judgement(s) are LLM-assisted and labelled advisory. Overall confidence is 0.6 — the weighted average across measured dimensions; it falls as more of the score leans on LLM-assisted judgement and rises when it's fully tool-backed.
Every figure here is one of three kinds, and we label which: ✓ Measured — a deterministic fact (LoC, complexity, coverage); ~ Modeled — an estimate from a stated model (cost, effort, value-at-risk), always a range with its assumptions, never a precise fact; ◐ Advisory — an LLM prose judgement. We never present a modelled estimate as if it were measured. Perfect or absent scores carry their provenance too (ADR-0011): ✓ Tool-verified means the property itself was measured across the surface; ○ Nothing flagged means the probes came back clean — a claim bounded by what a repository can show; ⊘ Not evidenced means a working control (a tested restore, an automated rollback) showed no positive evidence — absence of evidence is not evidence of a control, so it's excluded from the score rather than awarded a spurious 10; ◐ Sampled · advisory marks an LLM verdict over a bounded sample — advisory, never a deterministic measurement.
What we checked — 45 dimensions across the health lenses
Each chip is a dimension scored from real signals across architecture, testing, dependencies, security & compliance, documentation, git-history and code quality — in one coherent pass. A surface report typically covers a handful.
How to trust any code-health report — three questions
Can you open the finding? Real findings cite a repo-relative file and line you can open at the cited line — never an absolute scratch path. Here, 3003 of 3018 do; the remainder are repo-wide signals — a dimension-level measurement, not a single line. (Every path in this report is repo-relative by construction: paths are normalized at the producer and the report is rejected if any rooted path leaks through.)
Is there a tool behind the number? Every score below names the method that produced it — Roslyn, git, a scanner, or (for a handful of documentation/naming dimensions) an LLM labelled sampled · advisory — not a narrative.
Does re-running give the same result? Run it again on the same commit and the score — and this report, byte for byte — is identical. A report whose numbers move between runs is describing the run, not the code.
This report answers yes to all three. That's the bar to hold any assessment to.

What ran differently this time — a tool absent, degraded, or that fell back to an estimate. Named openly, not folded silently into the scores. A degraded run also records its exact cause in diagnostics.md.
D19 Documentation Quality — LLM provider failed — The model provider returned an unusable result, so this LLM-assisted dimension fell back to a measurement gap (confidence 0) rather than a penalty. Re-run with a reachable provider to score it.
Repo exclusion declarations: 14 pattern(s) declared (.gitattributes linguist-generated/vendored, .editorconfig generated_code) excluded 0 source file(s) from code-quality scoring. Declarations are the repo's own visible statement that a tree is machine-written or vendored — auditable in any diff, honored by GitHub the same way.
Limitations & what we did not check
Watchdog assesses the repository exactly as committed, and only the repository. By design it does not reach outside the source tree: the live cloud account, the running CI/CD pipeline, the host's branch-protection and approval rules, the production configuration, or a restore actually exercised against a backup are all out of scope. That boundary is a feature, not a gap — a repo-relative, deterministic scan re-runs identically on any commit and every finding opens at a real file and line, where a live audit can neither be reproduced nor traced. The visible consequence is that controls which leave no in-repo evidence are reported as "not evidenced" and excluded from the score rather than awarded a number a static scan cannot justify.
Per-dimension blind spots
For each dimension that was measured, what a static, repo-only scan structurally cannot see — the honest edge of the measurement, not a failure of it.
D1 Cyclomatic Complexity: Cyclomatic complexity counts branches statically — it cannot tell an essential decision tree from accidental tangle, nor see complexity that lives in data or configuration (large switch-case token tables, DSL lexers/parsers, data-as-code rule tables) rather than control flow: a tokenizer's many single-character cases read as high complexity though each branch is trivial.
D2 Cognitive Complexity: Cognitive-complexity heuristics approximate how hard code is to follow; genuine domain difficulty and well-named intent that eases reading are not captured.
D3 God Classes: "God class" is sized by members and responsibilities visible in the type — a deliberately broad facade over a coherent subsystem can read the same as an accidental grab-bag. For front-end JS the file-length check is cohesion-aware (a single-responsibility module — one class/IIFE — earns a 3× threshold), but cohesion is approximated from top-level declarations, not true dependency structure.
D4 Code Duplication: Duplication is token-similarity (jscpd) — it finds copy-paste, not semantic duplication expressed differently. Committed machine-written code (scaffolded migrations, designer/codegen output, protobuf/OpenAPI stubs, model snapshots) is EXCLUDED — its repetition is the tool's, not the team's — so the score reflects hand-written duplication only.
D13 Secret Scanning: Secret detection is signature- and entropy-based on the current tree — a secret that does not match a known pattern, or one already rotated, will not be flagged (a clean scan is "nothing matched", not "no secrets exist").
D15 Churn × Complexity Hotspots: Churn hotspots come from git history — a freshly imported or squashed repository has no churn signal, and recent rewrites can mask a historically risky file.
D16 Bus Factor: Bus-factor is a time-decayed model of commit attribution (who has recently, repeatedly worked a file), not comprehension — pairing, review and reading-without-committing spread knowledge it can't see; bot commits and shared accounts still distort it.
D21 Naming Consistency: Naming quality is an LLM judgement over a bounded sample — it assesses clarity/consistency of the names it sees, not domain-correctness, and is advisory.
D28 Secrets (history): Secret-history scanning sweeps the git log for known patterns — a secret that predates the available history, or never matched a signature, is not found (clean means "nothing matched in the history we can see").
D29 Static Analysis (SAST): SAST findings are pattern-based (semgrep) — it finds classes of bug it has rules for; logic flaws, auth/authorization gaps and issues needing runtime context are out of reach (and clean means "no rule matched").
D31 IaC & Container Security: IaC scanning checks Dockerfiles/Terraform/Kubernetes against best-practice rules — it cannot see the live cloud account, runtime configuration, or drift between the committed config and what is actually deployed.
D33 JS/npm Dependency Vulnerabilities: JS/npm CVE matching reads package manifests and lockfiles — risk from how a dependency is used, and advisories not yet published, fall outside this scan.
D34 Knowledge Freshness: Freshness is decayed commit RECENCY, not comprehension — code read often but rarely committed reads as orphaned, and stable code that genuinely needs no changes is penalised the same as forgotten code; bot/squash commits distort it like the bus factor.
D35 Change Coupling: Change coupling is co-change in COMMITS — files split across separate commits, or coupled only through a shared config/build step, read as uncoupled, and a sweeping commit (rename/format) is excluded so it doesn't couple everything. It shows that files change together, not WHY: a high coupling can be a healthy cohesive pair as readily as a hidden leak.
AC1 Text alternatives: Alt-text is detected structurally — the scan sees that an alternative EXISTS, not whether it meaningfully describes the image, and decorative-vs-missing is judged by attribute shape; runtime-injected images and a non-role=img decorative svg are out of scope. This is accessibility readiness, never a WCAG conformance claim.
AC2 Forms & labels: Label association is read from static markup — a label wired up at runtime (JS-set aria-labelledby, framework-injected ids) reads as missing, a present label says nothing about whether its text is correct. A known UI-library field component (e.g. a JSX <TextField>) is now checked conservatively — flagged only when it carries NO label/aria-label/aria-labelledby/id/name — but wrapper/context-labelled libraries (Chakra/Radix FormControl+FormLabel) aren't statically visible (possible false positive) and non-JSX lowercased components are still skipped. A clean result is "no unlabelled native control found", not a labelling proof.
AC3 Page structure: Page structure is read from the static markup tree — landmarks, headings and lang injected at runtime aren't seen, heading ORDER is checked structurally (not against the rendered visual hierarchy), and lang/title/main fire only on full documents, never partials, and the data-table check sees header-cell presence (a <th> exists), not whether each header correctly associates with its cells. Static readiness, not conformance.
AC4 Keyboard semantics: Keyboard semantics are inferred from markup attributes — interactivity wired purely in script, focus managed at runtime, and component-level handlers are invisible. A clean result means "no static keyboard-trap shape", not a keyboard-operability proof.
AC5 ARIA correctness: ARIA correctness is checked against the static role/attribute shape — roles/attributes set dynamically aren't seen, a valid role says nothing about whether it matches the element's real behaviour, and required-state checks are suppressed when a JSX spread could supply them.
AC6 Visual & motion safety: Contrast and motion safety are PARTIAL by construction — literal colours (hex/rgb/hsl/named) in inline styles, in-repo <style> blocks, in-repo .css files, var() tokens, Tailwind neutral utilities and CSS-in-JS top-level declarations are read (same-rule/same-element colour+background pairs only); computed/runtime/theme colour, external-CDN stylesheets, CSS-in-JS dynamic (${…}) and nested-selector colours, cross-element pairs and image contrast stay out of reach, so a clean result is bounded by what the static CSS itself shows.
AC7 A11y enforcement: Enforcement is scored from in-repo config/CI evidence only — an a11y gate enforced in external tooling with no in-repo trace can't be credited, and a configured linter is presence, not proof the rules actually run or block a merge.
DM6 Domain ↔ infrastructure boundary: Infrastructure reached through a hand-rolled wrapper, a domain-named facade, reflection, or a string-keyed service locator resolves to a non-infra type and isn't seen; the body scan is symbol resolution over syntax, not full dataflow. A clean result means "no resolved infra reference in a domain body", not a proof of purity.
M4 Documentation accuracy: Onboarding quality is an LLM read of the docs/setup present — it cannot run the onboarding or measure how long a real new joiner takes; the verdict is sampled and advisory.
P4 Deployment & Rollback: Approval/branch-protection rules live in repository settings the scan cannot see — only their in-repo evidence (config files, workflows) is checked, so a control enforced purely in the host's settings reads as "not evidenced".
P6 Release Hygiene: Rollback/observability controls are inferred from repo artefacts (pipelines, dashboards-as-code) — controls configured in external tooling, with no in-repo trace, cannot be credited.
The LLM boundary
LLM-set scores this run (2): D21, M4 (model: Local LLM). For these, a model reads a bounded sample and sets the numeric score (documentation, ADR quality, naming, comment value, onboarding) — D25 sets the ADR-conformance fraction over sampled code, D22 judges API accuracy over a sample. These are sampled and advisory by design: they vary at the margins between runs and are never a deterministic measurement. Every other score in this report is tool-computed at confidence 1.0.
What it measures: How tangled the control flow is — methods with many branches are hard to test and change.
Method: Cyclomatic complexity per method (1 + decision points), computed exhaustively across production source; test projects separated by convention. Deterministic.
448 method(s) exceeded the cyclomatic complexity threshold of 15; the worst was DFSAdmin.run at 105. A further 16 method(s) were over the threshold but excluded as flat dispatchers (a long switch/match over independent cases: many branches, almost no nesting), the largest being RouterClientMetrics.incInvokedMethod at 108 — they are counted neither in the figure above nor in this dimension's score.

What it measures: Whether any secrets were ever committed — scanned across the full git history, not just now.
Method: Git-history secret scan via gitleaks detect over full history in an isolated checkout; each match flagged High. Exhaustive; degrades cleanly when tool absent.

Method: File orphaning as total living-knowledge decay below one focused-commit's worth within a year, computed per-file from the D16 decay model. Exhaustive, deterministic over fixed history.
2442 of 2909 significant source file(s) are orphaned — their living knowledge has decayed to nothing, so no one currently understands them. The largest is hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/webapp/hamlet2/Hamlet.java.

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 the build pipeline provides supply-chain integrity — generated provenance/attestation, signed artifacts (cosign/sigstore), an SBOM, and pinned build actions. Presence of the configuration, not a runtime guarantee.
Method: Supply-chain provenance/signing read deterministically from CI/build config (.github/workflows, .gitlab-ci.yml, azure-pipelines, Jenkinsfile, .circleci) + the release surface: four signals — generated provenance/attestation (SLSA/in-toto/actions-attest), artifact signing (cosign/sigstore/gitsign), an SBOM (syft/sbom-action/*.spdx.json/*.cdx.json), and SHA-pinned build actions — scored 10·present/denom. NotApplicable without a build pipeline. Detects configuration presence, not runtime enforcement.

What it measures: Whether the repository publishes a coordinated-vulnerability-disclosure policy (SECURITY.md or security.txt) with a reporting contact, so finders know how to report a vulnerability. Presence of a policy file with a contact, not whether the policy is adequate or honoured.
Method: Vulnerability-disclosure policy read deterministically from the repo: a SECURITY.md (root/.github/docs) or .well-known/security.txt / security.txt, regex-checked for a reporting contact (email / URL / mailto). Present + contact → 10; present without a contact → 4; NotApplicable when no policy file exists (it may live off-repo). Detects the policy file's presence + contact, not its adequacy.
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.

Frontend & cross-cutting dimensions
R = React/JS · M = Maturity · P = Readiness.
AC1 · Text alternatives4.8 / 10Weak✓ Tool-verified
Other · Accessibility — Whether non-text content carries a text alternative — img/area/input[type=image] have alt, a meaningful svg has a title or aria-label, video has a captions track, and object/embed/canvas have a name or fallback content. Static markup readiness, not a WCAG conformance claim.
Method: Static markup-model scan: every img/area/input[type=image] checked for alt, svg[role=img] for a title/aria-label, video for a captions <track>. Components skipped, spreads suppressed. Deterministic, hard fact per element.
An image with no alt (and no aria-label/aria-labelledby) is unreadable to assistive tech. Add alt — alt="" if it's purely decorative. — index.html:29
What to do
Add a text alternative — alt on images (alt="" for purely decorative ones), a title or aria-label on meaningful svg, an aria-label or inner fallback content on canvas, and a captions <track> on video.

AC2 · Forms & labels5.0 / 10Adequate✓ Tool-verified
Other · Accessibility — Whether form controls have a programmatic label (an associated label, aria-label or aria-labelledby), buttons have text, links have an accessible name, fieldsets have a non-empty legend, known UI-library field components carry a label prop, and a placeholder isn't used as the only label. Static markup readiness, not a WCAG conformance claim.
Method: Static markup-model scan: inputs/selects/textareas checked for an associated label[for]/wrapping label/aria-label/aria-labelledby (per document), buttons for accessible text, fieldsets for a legend; placeholder-only labelling flagged. Deterministic, hard fact per control.
This control has no associated label. Add a <label for> / wrapping <label> / aria-label / aria-labelledby so assistive tech can name it. (×22) — explorer.html:80, explorer.html:89, explorer.html:144, …
This control has only a placeholder — a placeholder is not a label (it vanishes on input and many AT ignore it). Add a <label for>, a wrapping <label>, or aria-label. (×3) — explorer.html:120, explorer.html:120, home.html:21
What to do
Give every control a programmatic label (a <label for> / wrapping <label> / aria-label) and every button text — a placeholder is not a label.

AC3 · Page structure4.0 / 10Weak✓ Tool-verified
Other · Accessibility — Whether pages declare a language (well-formed BCP-47) and a non-empty title, expose exactly one main landmark and a sane heading order with non-empty headings, keep zoom enabled, title their iframes, give data tables header cells, and avoid meta-refresh. Static markup readiness, not a WCAG conformance claim.
Method: Static markup-model scan: html lang, document <title>, a main landmark and heading order on full documents only, plus zoom-disabling viewports, untitled iframes and meta-refresh anywhere. Deterministic, per structural checkpoint.
The page declares no language, so assistive tech can't pick the right pronunciation. Add lang (e.g. lang="en"). (×9) — index.html:14, index.html:14, index.html:14, …
A page with no <title> gives no name in the tab, history or screen-reader page list. Add a descriptive <title> in <head>. (×8) — index.html:14, index.html:14, index.html:14, …
No <main> (or role="main") means no "skip to content" target and a weaker landmark map. Wrap the primary content in <main>. (×8) — index.html:14, index.html:14, index.html:14, …
What to do
Declare <html lang>, a document <title> and a <main> landmark, keep headings in order, leave zoom enabled, title iframes and drop meta-refresh.
Other · Accessibility — Whether interactive behaviour is keyboard-reachable — no click handler on a non-interactive element lacking a role, tabindex and key handler, no positive tabindex, no href-less anchor, no placeholder-href (#/javascript) link acting as a button. Static markup readiness, not a WCAG conformance claim.
Method: Static markup-model scan: click handlers on non-interactive elements lacking role+tabindex+key handler, positive tabindex values, and href-less anchors. Components skipped, spreads suppressed. Deterministic, hard fact per element.
An <a> with no href, role or tabindex isn't focusable or keyboard-activatable. Give it a real href, or use a <button> for an action. (×12) — status.html:36, index.html:57, deploy.html:74, …
A click handler on a plain element isn't keyboard-operable. Use a <button>, or add role + tabindex="0" + a key handler. — NodeLabelsPanel.tsx:95
What to do
Make custom controls keyboard-operable (role + tabindex + key handler), drop positive tabindex, and give anchors a real href.
Other · Accessibility — Whether ARIA is used correctly — valid non-abstract roles, the ARIA state a role requires, valid (non-misspelled) aria-* attribute names, in-enum values for token-typed aria-* attributes, and no aria-hidden on (or wrapping) a focusable element. Static markup readiness, not a WCAG conformance claim.
Method: Static markup-model scan: role values checked against the WAI-ARIA role set (abstract/invalid flagged), required ARIA state for a role, and aria-hidden on a focusable element. Deterministic, role/attribute level.
aria-hidden="true" hides the element from assistive tech but leaves it keyboard-focusable — a confusing dead stop. Remove aria-hidden or make the element non-focusable. (×8) — explorer.html:61, explorer.html:112, explorer.html:139, …
What to do
Use valid, non-abstract roles, supply the ARIA state each role requires, and never put aria-hidden on a focusable element.
Other · Accessibility — Whether focus outlines aren't removed without a replacement, motion respects prefers-reduced-motion, and literal CSS colour pairs meet contrast — PARTIAL: inline styles, in-repo <style> blocks, in-repo .css files, var() tokens, Tailwind neutral utilities and CSS-in-JS literals are read (hex/rgb/hsl/named), never computed/runtime/external-CDN colour. Static markup readiness, not a WCAG conformance claim.
Method: Static markup/CSS scan: inline outline:none/0, literal inline colour/background contrast against the 4.5:1 AA floor, and <style>-block animation without a prefers-reduced-motion guard. Deterministic but PARTIAL — only inline styles and in-repo CSS literals are visible.
`.dataTables_processing` sets color: #999 on background-color: white — 2.8:1, below the 4.5:1 WCAG AA minimum for normal text. Darken or lighten one of them. — demo_table.css:59
`.form-control[disabled], .form-control[readonly], fieldset[disabled] .form-control` sets color: #999999 on background-color: #dddddd — 2.1:1, below the 4.5:1 WCAG AA minimum for normal text. Darken or lighten one of them. — bootstrap-hadoop.css:378
`.table.dataTable tbody tr.active td, .table.dataTable tbody tr.active th` sets color: white on background-color: #08C — 3.9:1, below the 4.5:1 WCAG AA minimum for normal text. Darken or lighten one of them. — dataTables.bootstrap.css:201
`header.bs-docs-nav, header.bs-docs-nav .navbar-brand` sets color: #fff on background-color: #5fa33e — 3.1:1, below the 4.5:1 WCAG AA minimum for normal text. Darken or lighten one of them. — hadoop.css:197
`.datepicker table tr td.selected, .datepicker table tr td.selected:hover, .datepicker table tr td.selected.disabled, .datepicker table tr td.selected.disabled:hover` sets color: #fff on background-color: #9e9e9e — 2.7:1, below the 4.5:1 WCAG AA minimum for normal text. Darken or lighten one of them. — bootstrap-editable.css:424
`.btn-warning` sets color: #fff on background-color: #f0ad4e — 1.9:1, below the 4.5:1 WCAG AA minimum for normal text. Darken or lighten one of them. — bootstrap.css:3372
What to do
Keep a visible focus style (don't remove the outline without a replacement), guard animation with prefers-reduced-motion, and raise low-contrast colour pairs to at least 4.5:1.

AC7 · A11y enforcement4.0 / 10Weak✓ Tool-verified
Other · Accessibility — Whether accessibility is ENFORCED in the toolchain — an a11y linter (eslint-plugin-jsx-a11y / vuejs-accessibility) configured, and axe/pa11y/Lighthouse wired into tests or CI — on the Documented→Verified→Prevented ladder.
Method: Repo config/CI scan: an a11y linter (eslint-plugin-jsx-a11y / vuejs-accessibility) configured, and axe/pa11y/Lighthouse in tests or CI, graded on the Documented→Verified→Prevented rungs. Deterministic, presence/rung detection.
No accessibility enforcement found — no a11y linter (eslint-plugin-jsx-a11y) and no axe/pa11y/Lighthouse in tests or CI. Start with the linter to catch issues at author time.
What to do
Enforce accessibility in the toolchain: add eslint-plugin-jsx-a11y, assert with vitest-axe in tests, then gate axe/pa11y/Lighthouse in CI.
Other · Architecture — Whether the codebase has a recognisable, scale-appropriate structure (a named architectural style, or modular enough for its size) rather than being an ad-hoc ball of mud.
Method: Roslyn plus csproj analysis: architecture style detection (DDD, clean, vertical-slice, CQRS) and structure fitness for repo size. Deterministic.
Other · Domain Modelling — Whether the domain layer stays free of infrastructure dependencies — a domain aggregate fused to a persistence ORM (TypeORM/Prisma/MikroORM/Sequelize/Mongoose) 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.
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.
The root README is 17 words — likely missing build/run/architecture context.
521 code files changed in the last 6 months but the README was not touched — it may no longer reflect the system.
What to do
Expand the README with getting-started, architecture overview and a project map.
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 an 'Architecture' / 'How it works' section to the root README — the high-level shape.
Add a README to the 108 of 121 project(s) that lack one — worth up to 1.8 pts.
Review the README against recent changes; refresh the parts that drifted.
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.
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.
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.

R1 · Type Safety3.8 / 10Weak✓ Tool-verified
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.
309 typed · 496 plain JS
What to do
Migrate the remaining .js/.jsx files to TypeScript.
React / JS · Architecture — Conformance to the detected frontend architecture layout (feature-sliced / layered src) plus cross-package deep-import rules (D-386).
Method: Conformance to the detected frontend layout (feature-sliced / layered src) plus cross-package deep-import rules, over the module graph. Deterministic.

What to do
Fix the listed violations: import through public entries (package exports / slice index), never reach into another layer or package's internals.
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. (×8) — QueueInfoTab.tsx:50, PropertyFormField.tsx:85, PropertyPanel.tsx:89, …
What to do
Break down the listed branch-heavy functions; aim P95 cyclomatic ≤ 5.

R3 · Large Files8.8 / 10Strong✓ Tool-verified
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.
What to do
Split the oversized components into smaller, focused ones.

R4 · Test Coverage3.5 / 10Weak✓ Tool-verified
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 — its behavior is unverified. (×8) — dfshealth.js, explorer.js, explorer.js, …
What to do
Add tests that import the unreached modules (directly or through their public entry).
React / JS · Readiness — How outdated the npm dependencies are (a maturity signal). JS/npm CVEs are scored separately in D33 (JS/npm Dependency Vulnerabilities).
Method: npm dependency staleness from manifest/registry metadata (a maturity signal; JS/npm CVEs are scored separately in D33). Deterministic.
44 outdated package(s); JS/npm CVEs scored in D33
What to do
Bump outdated dependencies to current versions to limit upgrade debt.

R6 · Tooling10.0 / 10Exemplary✓ Tool-verified
React / JS · Readiness — Whether the project wires up test, lint and typecheck — detected from each package.json script's COMMAND (eslint / tsc / vitest / jest / playwright), not just its name, and corroborated against CI-workflow invocations so a tool run only in CI still counts.
Method: package.json scanned for test/lint/typecheck script wiring. Deterministic presence check.
Do you agree with this assessment?
R7 · Dead Code8.9 / 10Strong✓ Tool-verified
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.
7 file(s) (~751 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. — hadoop-yarn-applications-catalog-webapp
471 file(s) (~26985 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. — webapp
Unreachable from the 15 application, 6 tooling and 262 test entry point(s) detected in this repo. Gate removals on your build/type-check — an undetected custom entry would make these reachable.
no import path from any entry point (15 application, 6 tooling, 262 test roots considered) (×5) — json-bignum.js, dataTables.bootstrap.js, yarn.dt.plugins.js, …
What to do
Delete the dead files and unused exports — every line is maintenance cost and rebuild-estimate inflation with zero runtime value.
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.
Imported but not declared in any reachable package.json — installs work only by hoisting accident. (×3) — abstract.js:18, app-timeout-bar-test.js:19, app-timeout-bar-test.js:20
Declared in hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-catalog/hadoop-yarn-applications-catalog-webapp/package.json but never imported anywhere in that package or its workspace members — dead weight and attack surface. Verify against build tooling before removing. (×3)
What to do
Remove unused dependencies, declare unlisted imports explicitly, and demote type-/test-only packages to devDependencies.
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.
Break each cycle by extracting the shared piece into a module both sides can import.

WCAG coverage — what static analysis assessed
Statically assessed 15 of 55 WCAG 2.2 Level A/AA success criteria (27%; ≈30% of the 50 WCAG 2.1 AA criteria for EN 301 549). The other 40 require runtime or manual evaluation. Partial signal only (a clean result is necessary, not sufficient; static analysis fully verifies none). This is accessibility readiness, not a conformance claim — a WCAG conformance claim requires manual evaluation (WCAG-EM 1.0).
The score is the rank-weighted fold of these lenses (worst-heaviest), each including its meta-dimensions; a lens with a Critical contributor is capped at Fair (its band reads "gated by …") and is never the strongest area however high its average.
Capped at Fair by a Critical contributor — resolve it before relying on this lens.
Not included — 67 check(s) not relevant to this codebase
These checks had nothing to measure here (no tests, no git history, the codebase is small, or the architecture style doesn't apply), so they're omitted above rather than scored low.
AX1 Captive dependencies — no DI registrations detected
AX10 Code composition — not assessed — code composition is computed by ROLE over the .NET document set and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
AX2 Stateful singletons — no singleton implementations detected
AX3 Project dependency cycles — not assessed — project cycles and dependency direction are computed over the .NET project-reference graph and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
AX4 Dependency direction — not applicable to a CQRS architecture (the inward-dependency rule is for layered/clean styles)
AX6 Interface segregation — not assessed — interface segregation is computed over the .NET type surface and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
AX7 Slice cohesion — not applicable — not a vertical-slice architecture
AX8 Test isolation — not assessed — test isolation is computed from the .NET project graph (which projects are test projects, and what they reference) and no such graph was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
AX9 CQS / query purity — no CQRS query handlers detected — query purity is not applicable to this codebase
AXB2 Runtime readiness — no data
C1 Data Protection — Not assessed: these personal data controls are read from C# source (attributes, middleware, entity/column names, guard methods) and no C# source was loaded for this repository — because it is written in another language, or the solution failed to load. Absence of a .NET idiom is NOT evidence that this repository lacks personal data controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
C2 Access Controls — Not assessed: these authorization controls are read from C# source (attributes, middleware, entity/column names, guard methods) and no C# source was loaded for this repository — because it is written in another language, or the solution failed to load. Absence of a .NET idiom is NOT evidence that this repository lacks authorization controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
C3 Audit Trail — Not assessed: these audit controls are read from C# source (attributes, middleware, entity/column names, guard methods) and no C# source was loaded for this repository — because it is written in another language, or the solution failed to load. Absence of a .NET idiom is NOT evidence that this repository lacks audit controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
C4 Data Retention — Not assessed: these retention controls are read from C# source (attributes, middleware, entity/column names, guard methods) and no C# source was loaded for this repository — because it is written in another language, or the solution failed to load. Absence of a .NET idiom is NOT evidence that this repository lacks retention controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
C5 Data-Subject Rights — Not assessed: these data-subject rights controls are read from C# source (attributes, middleware, entity/column names, guard methods) and no C# source was loaded for this repository — because it is written in another language, or the solution failed to load. Absence of a .NET idiom is NOT evidence that this repository lacks data-subject rights controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
D10 Test Quality — ~1183226 lines of test source are present (.java, .tsx, .ts) but the test-quality collector reads C# only, so skipped/assertion-free tests couldn't be counted. Not scored — this is a gap in the analyzer, not a finding about this repository.
D11 Test Reliability — Test reliability not included
D12 Dependency Hygiene — Dependency hygiene not measured — this repository's dependencies are not NuGet
D14 License Compliance — Not scored — this repository's package manifest is not parsed for licence data yet. A gap in the analyzer's language coverage, NOT a finding that the repository's licenses are compliant (a Maven POM), which this pass does not parse yet — so this dimension asserts nothing about this repository's licensing in either direction.
D17 Explicit Debt — the C# workspace loaded 0 projects, so explicit-debt density could not be measured
D18 Solution Shape — D18 scores the shape of a C#/VB .NET solution; this repository's .NET projects are all F# (.fsproj), which the C#/VB workspace does not load, so the dimension does not apply.
D19 Documentation Quality — LLM evaluation failed
D20 ADR Quality — N/A — ADRs are expected on deployable products with a user-facing host, not consumed libraries; no ADR log is required here.
D22 Internal API Consistency — No exposed public API
D23 Boundary Type-Coupling — Production source is present (.java, .py, .ts, .tsx) but bounded contexts are resolved over the C#/VB project set, which exposed none, so context scope could not be assessed. Not scored — this is a gap in the analyzer, not a verdict about this repository. Declaring the codebase's bounded contexts (≥2) would let cross-boundary type coupling be assessed — see the recommendation on this dimension for where. Declare them in `.codehealth/config.yaml` at the repository root (create it if absent), mapping each context name to the namespace prefixes that belong to it — e.g. `architecture:` → `contexts:` → `Billing: ["Acme.Billing"]`, `Catalog: ["Acme.Catalog"]`.
D24 Comment Value — No inline comments to assess — comment value is not applicable here.
D25 ADR Conformance — no ADRs to check
D26 Project Cohesion — Project cohesion is assessed over the .NET project set; this target exposed no projects, so project size and spread could not be assessed. Not scored — this is a gap in the analyzer's reach, not a verdict about this repository.
D27 Navigability — No calls could be sampled, so navigability was not assessed — tracing effort is measured over resolved call sites and this target exposed none. Not scored — this is a gap in the analyzer's reach, not a verdict about this repository.
D30 Dependency Vulnerabilities — the solution did not restore on the analyzer's .NET SDK (an SDK/target-framework/restore mismatch, common for an older codebase), so there was no restored dependency graph to scan for NuGet CVEs — excluded rather than scored; re-run on an SDK that can restore this solution
D32 Data Compliance (PII/GDPR) — No PII/GDPR ruleset is bundled (the public p/gdpr semgrep pack was retired) — data compliance is not assessed in this scan.
D39 IL Efficiency — D39 measures the IL emitted by a .NET build; this repository has no .NET solution or project files, so the dimension does not apply.
D40 Network Egress Confinement — No Kubernetes/orchestration workloads found in the repository manifests; network egress policy is a cluster-native control that may live at the platform/firewall layer, so there is nothing to assess here.
D41 Kernel & Syscall Confinement — No Kubernetes/orchestration workloads found in the repository manifests; seccomp/AppArmor/SELinux confinement is a workload-level control, so there is nothing to assess here.
D42 Runtime Threat Enforcement — No Kubernetes/orchestration workloads found in the repository manifests; runtime threat-detection and admission-control policy are cluster-level controls, so there is nothing to assess here.
D5 Coupling — Inter-project coupling could not be assessed — no analyzable project graph was found for this repository. Not scored: a gap in the analyzer's reach, not a verdict about this repository. (Coupling here is Martin afferent/efferent/instability plus reference cycles across a project-reference graph, read today from .NET project files; other ecosystems' module graphs are not read yet.)
D6 Cohesion (LCOM4) — Cohesion (LCOM4) is measured over a C#/VB class graph, and this repository's production source is .java, .py, .ts, .tsx, which this pass does not read — so no class could be assessed. Not scored — this is a gap in the analyzer, not a finding about this repository.
D7 Architectural Integrity — no checkable ADRs and no dependency cycles — architectural integrity not assessed
D8 Code Coverage — Coverage not included — suite not readable by the collector
D9 Test Distribution — Test source is present (.java, .tsx, .ts) but the test-pyramid classifier reads C# only, so its unit/integration/BDD/E2E split couldn't be counted. Not scored — this is a gap in the analyzer, not a finding about this repository.
DM1 Aggregate boundaries — not gated in TS source-only: aggregate-vs-value-object classification is not 0-FP-separable (every class-holding-class reads alike) — advisory (the Swift/Dart/Rust parity)
DM2 Strongly-typed ids — not gated in TS source-only for the Stage-D scaffold: the branded-type idiom (`type Id = string & {__brand}`) is idiom-rare in TS (4 calibration carriers), so a bare-string-id gap is advisory — Stage-E diversification target (tsjs-stageC.md LESSON-A)
DM3 Integration-event coupling — not gated in TS source-only: a cross-package domain leak is not 0-FP-separable from a legitimate shared-kernel package, and most calibration repos are single-package — advisory (candidate-demote)
DM4 Rich vs anemic model — not gated in TS source-only for the Stage-D scaffold: the anemic-vs-rich gate is candidate-DETERMINISTIC for TS (behaviour + the component/DTO/readonly-VO exemptions) but the calibration corpus is high-quality (0 witnesses) — advisory, settled at the Stage-E holdout (the Rust/Swift/Dart precedent)
DM5 Encapsulated state — not gated in TS source-only for the Stage-D scaffold: TS idiom favours #private/private/readonly (idiom-rare public-mutable break), so DM5 is advisory pending Stage-E messier-repo witnesses (the Rust/Swift/Dart precedent)
DM7 Repository granularity — not gated in TS source-only: 'a repository per CHILD entity' needs the aggregate-root structure, which is not source-resolvable; the softest gated dim — advisory
ED1 Event-Driven — not run — only 1/3 markers (112 CQRS handler(s))
ED5 Idempotency — no mutating command handlers or message consumers detected — idempotency check not applicable
ES1 Event Sourcing — not run — 0/3 markers found
GD1 Unfinished & placeholder code — no source files
IC1 Incompleteness & stubs — not analysed — these correctness checks are read from C# source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
P12 CI test-gate honesty — no data
P2 Observability — Observability was not assessed: this check reads .NET source (ILogger/Serilog, OpenTelemetry, health checks) and no such source carries this repository's product — because it is written in another language, or because the solution failed to load. Absence of a .NET logging idiom is NOT evidence that this repo lacks structured logging (it may log through its own ecosystem's logger). This is a gap in the analyzer, not a finding about this repository.
P5 DR & Backup — not evidenced — repo shows no backup/RTO/RPO controls; absence of evidence is not evidence of a working control
P7 Outbound HTTP resilience — not applicable — this isn't a service/API/worker
P8 Schema migrations — not assessed — schema-migration practice is read from EF Core usage in .NET source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
P9 Domain vs controller coverage — no coverage report found on disk — produce a coverage report in a standard format (JaCoCo XML — `mvn jacoco:report`) into the repo working tree before the scan — a CI step is the usual place, since the artefact is commonly gitignored, or wire coverage collection into CI, to enable this cross-layer check
PF1 Benchmark discipline — Performance was not assessed: this lens reads .NET source (allocation-aware APIs — Span/Memory, ArrayPool/ObjectPool, stackalloc — and a BenchmarkDotNet suite) and no such source was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository — in particular it is NOT a statement that this repo is unpackaged or performance-careless.
PF2 Allocation hygiene — Performance was not assessed: this lens reads .NET source (allocation-aware APIs — Span/Memory, ArrayPool/ObjectPool, stackalloc — and a BenchmarkDotNet suite) and no such source was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository — in particular it is NOT a statement that this repo is unpackaged or performance-careless.
PF3 Async & latency hygiene — Performance was not assessed: this lens reads .NET source (allocation-aware APIs — Span/Memory, ArrayPool/ObjectPool, stackalloc — and a BenchmarkDotNet suite) and no such source was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository — in particular it is NOT a statement that this repo is unpackaged or performance-careless.
S1 Web-Security Posture — Not assessed: these web-security controls are read from C# source (attributes, middleware, entity/column names, guard methods) and no C# source was loaded for this repository — because it is written in another language, or the solution failed to load. Absence of a .NET idiom is NOT evidence that this repository lacks web-security controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
SC1 Supply-chain hygiene — no data
X1 Async correctness — not analysed — these correctness checks are read from C# source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
X2 Cancellation propagation — not analysed — these correctness checks are read from C# source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
X3 Exception handling — not analysed — these correctness checks are read from C# source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
X4 Structured logging — not analysed — these correctness checks are read from C# source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
X5 Nullable reference types — not analysed — these correctness checks are read from C# source and none was loaded for this repository, because it is written in another language or the solution failed to load. This is a gap in the analyzer, not a finding about this repository
Appendix A — Findings (grouped)
The findings behind the scores, grouped by severity, then by dimension and kind. The high-severity issues are enumerated in full below; items per group are capped at 25 with any overflow stated explicitly per group, never silently truncated. The complete machine-readable list of every finding (all severities) is the companion findings.md in this report's bundle.
High: run-shell-injection .github/actions/build_image/action.yml:58— Using variable interpolation `${{...}}` with a workflow input in a `run:` step could allow an attacker to inject their own code into the runner. This would allow them to steal secrets and code. A workflow input is not bounded by this step and should be treated as untrusted. Instead, use an intermediate environment variable with `env:` to store the data and use the environment variable in the `run:` script. Reference it as a shell VARIABLE rather than a `${{ }}` interpolation, using your shell's own syntax (`"$ENVVAR"` in bash, `$env:ENVVAR` in PowerShell), so the value is passed as data and never re-expanded as code.
High: run-shell-injection .github/actions/build_image_url/action.yml:38— Using variable interpolation `${{...}}` with `github` context data in a `run:` step could allow an attacker to inject their own code into the runner. This would allow them to steal secrets and code. `github` context data can have arbitrary user input and should be treated as untrusted. Instead, use an intermediate environment variable with `env:` to store the data and use the environment variable in the `run:` script. Reference it as a shell VARIABLE rather than a `${{ }}` interpolation, using your shell's own syntax (`"$ENVVAR"` in bash, `$env:ENVVAR` in PowerShell), so the value is passed as data and never re-expanded as code.
High: github-script-injection .github/workflows/cloud_aws.yml:72— Using variable interpolation `${{...}}` with a workflow input in a `actions/github-script`'s `script:` step could allow an attacker to inject their own code into the runner. This would allow them to steal secrets and code. A workflow input is not bounded by this step and should be treated as untrusted. Instead, use an intermediate environment variable with `env:` to store the data and use the environment variable in the `run:` script. Reference it as a shell VARIABLE rather than a `${{ }}` interpolation, using your shell's own syntax (`"$ENVVAR"` in bash, `$env:ENVVAR` in PowerShell), so the value is passed as data and never re-expanded as code.
High: run-shell-injection .github/workflows/cloud_aws.yml:95— Using variable interpolation `${{...}}` with a step output / a workflow input in a `run:` step could allow an attacker to inject their own code into the runner. This would allow them to steal secrets and code. A step output / a workflow input is not bounded by this step and should be treated as untrusted. Instead, use an intermediate environment variable with `env:` to store the data and use the environment variable in the `run:` script. Reference it as a shell VARIABLE rather than a `${{ }}` interpolation, using your shell's own syntax (`"$ENVVAR"` in bash, `$env:ENVVAR` in PowerShell), so the value is passed as data and never re-expanded as code.
High: github-actions-mutable-action-tag .github/workflows/codeql.yml:64— GitHub Actions step uses a mutable tag or branch reference. Tags and branch names can be silently repointed by the action owner, enabling supply-chain attacks — as seen in the trivy-action and kics-github-action compromises.

High: ldap-injection hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/LdapGroupsMapping.java:509— Detected non-constant data passed into an LDAP query. If this data can be controlled by an external user, this is an LDAP injection. Ensure data passed to an LDAP query is not controllable; or properly sanitize the data. This is a semgrep security-AUDIT rule: it reports that a sensitive construct is present, not that it is exploitable here. Confirm whether this site handles untrusted input or is reachable across a trust boundary — and apply the change where it is; where the construct is required by the platform or protocol it calls into, and carries no untrusted data (a syscall/FFI shim, a build- or debug-gated tool, a fixed local surface), record the review and leave the code as it is.

High: insecure-use-strcat-fn hadoop-common-project/hadoop-common/src/main/native/src/org/apache/hadoop/net/unix/DomainSocket.c:323— Finding triggers whenever there is a strcat or strncat used. This is an issue because strcat or strncat can lead to buffer overflow vulns. Fix this by using strcat_s instead. This is a semgrep security-AUDIT rule: it reports that a sensitive construct is present, not that it is exploitable here.

High: insecure-use-string-copy-fn hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfs-tests/test_libhdfs_threaded.c:221— Finding triggers whenever there is a strcpy or strncpy used. This is an issue because strcpy does not affirm the size of the destination array and strncpy will not automatically NULL-terminate strings. This can lead to buffer overflows, which can cause program crashes and potentially let an attacker inject code in the program. Fix this by using strcpy_s instead (although note that strcpy_s is an optional part of the C11 standard, and so may not be available).

High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-catalog/hadoop-yarn-applications-catalog-webapp/yarn.lock— angular 1.6.10: [GHSA redacted] — no fixed version has been published yet. Track the advisory, and remove or replace angular if the exposure is not acceptable until one lands. One upgrade of angular 1.6.10 clears all 12 advisories it raises: [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted], [GHSA redacted].
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/yarn.lock— async 2.6.3: [GHSA redacted] — async is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (or pin async to 2.6.4 with an `overrides` entry (`resolutions` if you use Yarn)).
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/yarn.lock— body-parser 1.14.2: [GHSA redacted] — body-parser is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (or pin body-parser to 1.20.3 with an `overrides` entry (`resolutions` if you use Yarn)). This is 1 of 2 advisories this scan raises against body-parser 1.14.2, and their fixed versions do not agree — anything below 1.20.6 still leaves at least one of them open, so 1.20.6 is the floor for this package, not this row's target alone.
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-catalog/hadoop-yarn-applications-catalog-webapp/yarn.lock— brace-expansion 1.1.12: [GHSA redacted] — brace-expansion is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (or pin brace-expansion to 1.1.16 with an `overrides` entry (`resolutions` if you use Yarn)). This is 1 of 3 advisories this scan raises against brace-expansion 1.1.12, and their fixed versions do not agree — anything below 1.1.16 still leaves at least one of them open, so 1.1.16 is the floor for this package, not this row's target alone. (in 2 lockfiles) One upgrade of brace-expansion 1.1.12 clears all 3 advisories it raises: [GHSA redacted], [GHSA redacted], [GHSA redacted].
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/yarn.lock— braces 1.8.5: [GHSA redacted] — braces is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (— 3.0.3 is a MAJOR ahead of the resolved 1.8.5, so an `overrides` pin would force a breaking version under a dependent written against 1.8.5; upgrading the declaring package is the remedy, and where no patched release exists in your major line, record the exposure instead).
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/yarn.lock— cross-spawn 5.1.0: [GHSA redacted] — cross-spawn is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (— 6.0.6 is a MAJOR ahead of the resolved 5.1.0, so an `overrides` pin would force a breaking version under a dependent written against 5.1.0; upgrading the declaring package is the remedy, and where no patched release exists in your major line, record the exposure instead).

One upgrade of debug 0.7.4 clears all 2 advisories it raises: [GHSA redacted], [GHSA redacted].
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/yarn.lock— dot-prop 3.0.0: [GHSA redacted] — dot-prop is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (— 4.2.1 is a MAJOR ahead of the resolved 3.0.0, so an `overrides` pin would force a breaking version under a dependent written against 3.0.0; upgrading the declaring package is the remedy, and where no patched release exists in your major line, record the exposure instead).
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/yarn.lock— engine.io 1.8.0: [GHSA redacted] — engine.io is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (— 3.6.0 is a MAJOR ahead of the resolved 1.8.0, so an `overrides` pin would force a breaking version under a dependent written against 1.8.0; upgrading the declaring package is the remedy, and where no patched release exists in your major line, record the exposure instead). This is 1 of 2 advisories this scan raises against engine.io 1.8.0, and their fixed versions do not agree — anything below 3.6.1 still leaves at least one of them open, so 3.6.1 is the floor for this package, not this row's target alone. One upgrade of engine.io 1.8.0 clears all 2 advisories it raises: [GHSA redacted], [GHSA redacted].
High CVE: [GHSA redacted] hadoop-yarn-project/hadoop-yarn/hadoop-yarn-capacity-scheduler-ui/src/main/webapp/package-lock.json— flatted 3.3.3: [GHSA redacted] — flatted is not declared in this repo's manifests: it is pulled in transitively, so upgrade the dependency that requires it (or pin flatted to 3.4.0 with an `overrides` entry (`resolutions` if you use Yarn)). This is 1 of 2 advisories this scan raises against flatted 3.3.3, and their fixed versions do not agree — anything below 3.4.2 still leaves at least one of them open, so 3.4.2 is the floor for this package, not this row's target alone. One upgrade of flatted 3.3.3 clears all 2 advisories it raises: [GHSA redacted], [GHSA redacted].
