40 method(s) exceeded the cyclomatic complexity threshold of 15; the worst was findMusic at 44. A further 3 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 index.handleStartServer at 24 — they are counted neither in the figure above nor in this dimension's score. 3 files carry no cyclomatic complexity row at all for this reason — every one of their over-threshold methods was excluded, so the exclusion is disclosed nowhere in the file itself: src/main/modules/openApi/index.ts (index.handleStartServer at 24), src/renderer/views/List/MusicList/useMenu.js ((anonymous) at 16), src/renderer/views/List/MusicList/useMenu.js (useMenu.default at 16). They are named here because the per-file figures other dimensions report are taken BEFORE this exclusion, so such a file can show a high maximum complexity elsewhere in this report and nothing here, with nothing to reconcile the two.

Development dependencies are deliberately not graded: this dimension grades what SHIPS. Whether any of these packages is DEPRECATED or UNMAINTAINED is not graded — registry.npmjs.org's latest-version answer carries neither, and release age does not stand in for a maintenance status. Whether any is UNUSED is not graded either: that is a source question, and the frontend dependency lens (R8) answers it in this same run.

Licences were resolved from registry.npmjs.org over the 22 production dependency(ies) this repository's committed lockfile resolves, across 1 product package.json manifest(s). Its 57 `devDependencies` declaration(s) are excluded: a consumer installs none of them. ★ DEPTH: this is the DIRECT production set the lockfile resolves, NOT the transitive closure — only one of the four lock dialects this pass reads states a full graph, so a banned licence pulled in only by a dependency's OWN dependencies is outside this verdict, exactly as the JVM arm's declaration-site verdict is. ★ Each licence is the one the registry publishes for the package's CURRENT release rather than for the pinned version, which is the same caveat the Hex and RubyGems arms carry. This repository publishes itself under Apache-2.0, which is its own choice and is not judged here.

Method: Dependency-CVE scan across every ecosystem the repository declares, scored ONCE. Three sources are unioned and deduplicated by advisory identity (rule id + alias closure, CVE<->GHSA) scoped to package+version, keeping the worst severity: `osv-scanner --recursive` over osv.dev for Dart pub, Elixir/Hex, Go, Java and Kotlin via Maven/Gradle, npm, PHP/Composer, Python/PyPI, RubyGems, Rust/Cargo and Swift; `trivy fs --scanners vuln` for npm lockfiles; and `dotnet list package --vulnerable --include-transitive` for NuGet (with per-advisory collapse of the project x target-framework fan-out), plus a DECLARED-dependency arm that resolves a published gem's gemspec against rubygems.org where no Gemfile.lock is committed. `SeverityScore(c,h,m,l, normalizer 8.0)`.

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. A non-source file is never a coupling PARTICIPANT either: documentation, schemas, config and data files are dropped with the rest, so a code↔docs pair — a command and the reference page that restates it — is not reported however strongly the two co-change; nor is coupling that runs THROUGH a build step or config file.

What it measures: Whether any dependency the repository declares is published as MALICIOUS rather than merely vulnerable — a package that is an attacker's work, in any ecosystem osv-scanner reads. Scored apart from D30 because the answer is binary: there is no safe version to upgrade to, and the fix is to remove the package and rotate every credential it could have read.

Method: The same dependency scan D30 reads, partitioned on the scanner's own classification rather than rescanned: a row is MALICIOUS when its id is in the `MAL-` space (the ossf/malicious-packages feed) OR its `database_specific.cwe_ids` carries `CWE-506` ("Embedded Malicious Code"). Both channels are structural; the summary text is deliberately NOT read, because a malicious-package record whose summary says only "Critical severity vulnerability" is a real shape ([GHSA redacted]) and a text matcher misses it. Scored BINARY: any surviving row is 0, whatever its severity and however many CVEs sit beside it — a hostile dependency is not a quantity. Applicability and degradation are D30's: NotApplicable only when no ecosystem is readable, and an unscannable ecosystem degrades rather than reading clean. SCORED, not informational.

What it measures: Whether anyone still ships security patches for the platform this repository RUNS ON — the runtime it pins and the framework majors its own constraints hold it to. Separate from D12 because the question differs: a current Django on an end-of-life Python is perfectly up to date and completely unsupported, and the fix is a migration rather than a version bump. What the repository says it merely SUPPORTS is never charged.

Method: End-of-life PLATFORM read from the repository's own declarations and graded against a FROZEN, dated table of vendor support dates — no network, no feed, no API, so this dimension answers identically inside a closed scan fence. Two subjects: a RUNTIME the project pins (a single or all-end-of-life TargetFramework, a .nvmrc or .python-version, a requires-python CAP) and a FRAMEWORK major a dependency constraint cannot move off (a caret, tilde or exact version; `vue@^2.7.16` pins Vue 2). A FLOOR is deliberately never charged — `requires-python = ">=3.8"` states what a package SUPPORTS, not what it runs on — and a multi-target project is charged only when EVERY target is out of support. Runtime 4.0/product capped 8.0, framework 1.5 capped 4.5. The table is safe to freeze because a statement about support that ended in the past cannot become false: it loses recall as it ages, never precision, and a test asserts every entry predates the freeze date. Disjoint from D31 (a container image's OS layer) and D29 (the toolchain a CI workflow installs). Abstains when the repository declares no platform this pass reads — never scores it clean.

A FLOOR is deliberately never charged: `requires-python = ">=3.8"` states what the package SUPPORTS, not what it runs on, and a well-maintained library declares exactly that while running its own CI on a current release. The end-of-life facts are FROZEN and dated, so this dimension needs no network and answers identically inside a closed scan fence; as the table ages it loses recall and never precision, because a statement about support that ended in the past cannot become false. The OS layer of a container image is D31's question and the toolchain a CI workflow installs is D29's; this row is neither.

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.

Coverage: Population: image/media elements — img, area, input[type=image], svg, video, object, embed, canvas — across the PARSED MARKUP files only (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx); components, hidden subtrees and dynamic-attribute elements are skipped. Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is NOT read by any producer, so it contributes no element to this population; where such a frontend is present the card discloses it as an analyzer gap rather than scoring around it.

• A <canvas> with no aria-label/title and no inner fallback content can't be described by assistive tech. Add a name or fallback content. (×2) — src/renderer-lyric/components/common/AudioVisualizer.vue:3, src/renderer/components/common/AudioVisualizer.vue:3

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, a click handler on a plain element names the control it declares, 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.

Coverage: Population: form controls, buttons, links, fieldsets and known UI-library field components in the PARSED MARKUP files only (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx); components, hidden subtrees and spread/dynamic-attribute elements are skipped, so a control whose label arrives through a spread or a runtime expression is deliberately not judged. Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

• 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.

• This <label> has no for and wraps no form control, so it names nothing: assistive tech never announces it, and clicking the caption focuses no field. Note that an id on the label is not an association — it is the TARGET of one, so a control still has to point at it. Give the label for="<the control's id>", move the control inside the label, or point the control's aria-labelledby at this label's id. (×2) — src/renderer/views/Setting/components/ThemeSelectorModal.vue:15, src/renderer/views/Setting/components/ThemeSelectorModal.vue:28

Coverage: Population: the PARSED MARKUP documents (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx). The page-level checks — lang, title, single main landmark — fire ONCE PER FULL DOCUMENT (an <html> root) and never on a partial or component fragment, so a repo of fragments is assessed only on the per-element checks (heading order, table headers, iframe titles, meta-refresh, zoom). Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

Other · Accessibility — Whether interactive behaviour is keyboard-reachable — no click handler on a non-interactive element lacking a role, tabindex and key handler, no element the repo's own CSS styles `cursor: pointer` without giving it any of the three, no unfocusable element whose only binding is a mouse enter/leave pair or a double-click, 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.

Coverage: Population: interactive elements plus elements the markup gives a click/key handler or the repo's own CSS styles `cursor: pointer`, in the PARSED MARKUP files only (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx). Keyboard reachability is judged from the markup, never from a rendered page. ★ An interactive element declared in a tagged-template (html`…`) or hyperscript frontend is NOT in this population — no producer reads either — so an empty population is reported as an analyzer gap, never as "this repository has no interactive elements".

• This <li> carries tabindex="0", so it is in the tab order and a keyboard user will land on it — but its behaviour is bound to the pointer only, with no key handler. A tabindex makes an element focusable, not operable: Enter and Space fire a click on a native <button> or <a href> and nowhere else, so this can be focused and never activated. Use a <button>, or handle Enter/Space in a key handler. — src/renderer/components/base/Menu.vue:4
• This <div> binds mouse-enter and mouse-leave and nothing else — no click, no key handler, no focus handler, and no tabindex="0", so it cannot even take focus. A keyboard user cannot hover, so whatever the pair reveals or highlights is reachable with a mouse only. Bind the same state to focus/blur as well, and add tabindex="0"="0" so the element can receive that focus. — src/renderer/components/base/Popup.vue:3
• A click handler on a plain element isn't keyboard-operable. Use a <button>, or add role + tabindex="0" + a key handler. (×38) — src/renderer/components/base/Selection.vue:3, src/renderer/components/base/Selection.vue:12, src/renderer/components/layout/PactModal.vue:7, …

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.

Coverage: Population: elements in the PARSED MARKUP files (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx) that carry a role or an aria-* attribute; roles and token values are checked against the ARIA enums exhaustively within that set. An expression-valued (dynamic) role or aria-* value is skipped rather than guessed, and markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

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.

Coverage: Population: styled elements in the PARSED MARKUP files (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx), plus in-repo <style> blocks, in-repo .css files and CSS-in-JS literals. Colour contrast is computed from LITERAL colour pairs only (hex/rgb/hsl/named, including var() tokens and Tailwind neutral utilities) — computed, runtime-themed and external-CDN colour is never resolved, so this is a partial read of contrast by construction. Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

• outline:none/0 in an inline style removes the keyboard focus ring with no chance of a :focus replacement. Keep a visible focus indicator. (×2) — src/renderer/components/base/MusicList.vue:2, src/renderer/components/base/VirtualizedList.vue:2

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.

Other · Accessibility — Whether accessibility is ENFORCED in the toolchain — an accessibility checker configured over the markup (an a11y lint rule set, e.g. eslint-plugin-jsx-a11y or vuejs-accessibility where the project lints JavaScript) and an automated accessibility assertion wired into tests or CI (axe/pa11y/Lighthouse or an equivalent) — on the Documented→Verified→Prevented ladder.

Method: Repo config/CI scan: an accessibility checker configured over the markup (an a11y lint rule set such as eslint-plugin-jsx-a11y / vuejs-accessibility where JavaScript is linted) and an automated accessibility assertion in tests or CI (axe/pa11y/Lighthouse or equivalent), graded on the Documented→Verified→Prevented rungs. Deterministic, presence/rung detection.

Coverage: Population: the repository's own tooling configuration — lint config, test and CI files — NOT the markup. It is read for a configured accessibility checker and an automated accessibility assertion (axe/pa11y/Lighthouse, or a native-toolkit equivalent), and it credits an INVOCATION, never a mention: a licence filename, an import comment or a doc reference earns no rung. Enforcement configured entirely outside the repository leaves no evidence here and cannot be credited.

• No accessibility enforcement found — no a11y linter (eslint-plugin-vuejs-accessibility) and no axe/pa11y/Lighthouse in tests or CI. Start with the linter to catch issues at author time. What was searched, so you can tell an absence from a miss: the 95 markup file(s) this pass actually assessed, the linter configuration checked in beside them, and this repository's test and CI files — matched by name against the accessibility checkers this dimension carries. An audit run outside the repository, a hosted scanner, or a check whose name is not one of those, is not seen here.

What to do

• Enforce accessibility in the toolchain: add eslint-plugin-vuejs-accessibility, then assert with your test runner's axe binding (jest-axe, vitest-axe, cypress-axe or @axe-core/playwright) in tests, then gate axe/pa11y/Lighthouse in CI.

Other · Architecture — How the codebase splits by code ROLE — domain, application, infrastructure, test, generated. The significance map behind the knowledge/coupling weighting, and a DDD signal in its own right: a thin domain core under fat infrastructure is the anemic-domain smell, quantified. How each file's role is decided, because the split is only as good as that: a generated name or a build-output tree makes it Generated, a test project makes it Test, and otherwise the file's NAMESPACE and PATH words are matched against fixed vocabularies in a fixed ORDER — domain, then infrastructure, then application — so a file whose words hit two layers is counted under the earlier one. A production file matching none of them counts as application, so that share reads 'application or unclassified' rather than a measured application layer. Roles come from naming convention, never from what the code does. On this repository the split was taken from the source tree on disk rather than from a loaded .NET workspace, so a file's role is decided by its PATH segments alone — no declared namespace was available to add to the evidence — and generated output is excluded from the census entirely rather than counted as a generated share.

Method: Roslyn line-count by code ROLE: every source file classified Domain/Application/Infrastructure/Test/Generated by namespace + path convention (the shared CodeRoleClassifier), then significant lines summed per role. Deterministic; the advisory score is the business-logic (domain+application) share of production code.

Coverage: Population: ALL source files, each bucketed into ONE of five roles (Domain/Application/Infrastructure/Test/Generated) by namespace + path convention — a file whose layer isn't named in the convention falls to Application (the neutral default), and the split is line-count, not semantic depth or business value.

What to do

• The domain core is a small share of production code, but most of the rest matched no layer vocabulary at all — so this is not yet an anemic-domain finding. The namespace/path convention could not place that code, which makes the composition above a statement about the naming, not about the design. Name the layers (or check that the repository's conventions differ from the ones this check knows) before reading a thin domain into it.

Other · Architecture — Whether the project-reference graph is acyclic (cycles block independent build/deploy and signal eroding boundaries).

Method: Project reference cycles via elementary-DFS over real .csproj references, using the engine shared with D5/D7; cyclic versus acyclic. Exhaustive, deterministic.

Other · Architecture — Whether dependencies point inward (Domain ← Application ← Infrastructure/Web) — the clean-architecture dependency rule, checked across the project graph.

Method: Layer violations by name-segment inference (Domain/Core to Application to Infrastructure/Web) over the project-reference graph. Exhaustive over all projects, deterministic.

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 an 'Architecture' / 'How it works' section to the root README — the high-level shape.

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 — no conventional ADR directory, no numbered `NNNN-title` documents in any markup this check reads, and nothing ADR-shaped by content. Design rationale recorded elsewhere (a design-notes tree, a mailing list, pull-request discussion) is not visible to this check and is not re-findable per decision, so a future maintainer cannot ask why one choice was made and get an answer.
• No C4/Structurizr/PlantUML/Mermaid/Graphviz/D2 diagram, no drawn diagram named for the architecture, no file named `architecture` or `design` in any markup this check reads, and nothing in the README, docs or contributor guides that announces the shape — no `## Architecture` heading, no "architecture overview"/"high-level design" phrasing, no "the architecture is …" introduction, no guided code tour. A shape laid out in prose that never names itself as the architecture is not visible to this check, and neither is one kept outside the repository, so this row reports the absence of a re-findable shape document — not evidence that nobody wrote the shape down.

What to do

• Record significant decisions one document per decision — dated, stating the context, the decision and its consequences — and keep them together wherever your design docs already live (a conventional `docs/adr/` tree, with each file named `NNNN-title` in whatever markup those docs already use, is the most discoverable form).
• Add a C4 context/container diagram (Structurizr, PlantUML or Mermaid) or an architecture.md overview.

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.

What to do

• Start a test surface where your build system looks for one (tests/, test/, spec/, or your ecosystem's test source set) — the separation follows from putting the first tests in the right place.

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 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.

Readiness · Readiness — Whether the code is diagnosable in production — structured logging, tracing/metrics, health checks.

Method: Filesystem/Roslyn scan: structured-logging frameworks (Serilog, NLog), OpenTelemetry, and health-check endpoint patterns. Exhaustive, deterministic.

What to do

• Consider OpenTelemetry tracing/metrics (@opentelemetry/sdk-node) and a health-check endpoint (@godaddy/terminus or a /health route) for operability.

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.

• No static application security testing detected. For this repository's stack, add CodeQL's javascript-typescript pack, `semgrep --config=p/typescript`, or eslint-plugin-security as a CI step. What was searched, so you can tell an absence from a miss: the 14083 CI workflow file(s) in this repository, and the scanner and linter configuration checked in beside them. A scan that runs outside CI, one configured in your forge's web UI rather than in a committed file, or a tool whose name is none of those this check carries, is not seen — if that is your case the row is wrong, and saying so is more useful than adding a second scanner.

What to do

• Add a SAST step to CI running what this repository's stack ships: CodeQL's javascript-typescript pack, `semgrep --config=p/typescript`, or eslint-plugin-security — so a security regression fails the build instead of landing.
• 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.

• No release automation was found in CI — neither a deploy stage (Helm/Kubernetes/compose manifests, an orchestrated rollout) nor a publish job that ships the built artifact. Releases appear to be run by hand, which is slower, less repeatable and harder to reverse.

What to do

• Automate the release in CI — a deploy stage for a service (Helm/Kubernetes manifests or an equivalent rollout), or a tag-triggered publish job for an artifact — so releases are repeatable and reversible.

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.

Readiness · Readiness — Whether outbound HTTP calls are wrapped in resilience (retry/timeout/circuit-breaker) so a failing dependency doesn't cascade.

Method: Source scan: outbound HTTP clients and what bounds them — resilience handlers (Polly, AddStandardResilienceHandler) on .NET; on Go, the JVM, Python, JavaScript/TypeScript, Ruby, PHP, Rust, Elixir, Swift, Dart and Erlang, a timeout, deadline, retry or breaker beside each call, or a process-wide client default (a framework-wide deadline such as Drupal core's, Laravel's or actix's awc counts). Exhaustive, deterministic.

• `https.request(` makes an outbound HTTP call, and nothing bounds it: no timeout, deadline, retry or circuit breaker is set for it here, and the client has no process-wide default. A slow or failing dependency will hold this service's request, thread or connection until the call gives up on its own — or never, for a client with no default timeout. — src/common/utils/musicMeta/downloader.js:26

What to do

• Bound every outbound call: pass `signal: AbortSignal.timeout(ms)` to `fetch`, set `timeout` on the axios instance (`axios.create({ timeout })`), and add retries with back-off (`axios-retry`, `p-retry`) and a breaker (`opossum`, `cockatiel`) around dependencies that fail.

Readiness · Performance — Whether asynchronous code stays responsive — it avoids sync-over-async blocking (a .NET .Wait()/.GetAwaiter().GetResult(), a time.sleep or blocking HTTP call inside a Python coroutine, a *Sync call inside an async JavaScript function, block_on inside a Rust async fn, runBlocking inside a Kotlin suspend function, block() inside a Reactor publisher) that stalls a thread or event loop and risks deadlock, and, where the code is a reusable library on .NET, awaits with ConfigureAwait(false) so it never captures and stalls its caller's context.

Method: Production-source scan: sync-over-async blocking counted everywhere — .Wait()/.GetAwaiter().GetResult() in .NET; off .NET, read from the language model, a blocking call inside an async function (Python, TS/JS, Rust, Kotlin) or inside a Java method returning a Reactor Mono/Flux — and, for a .NET library with ≥5 awaits, the share of awaits using ConfigureAwait(false). Deterministic, syntax/text detection.

What to do

• TypeScript/JavaScript: use the promise APIs (fs/promises, a promisified child_process.execFile, the async zlib/crypto functions) and await them instead of the *Sync variants.

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.

• 323 typed · 304 plain JS — the untyped files are build-config/build-after-pack.js, build-config/build-before-pack.js, build-config/build-pack.js, build-config/dependencies-patch.js, build-config/deps.js, build-config/lib-update.js (+298 more).

What to do

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

React / JS · Code Health — Near-exact copy-pasted blocks of substantial extent across the frontend (the D4 clone algorithm over JS/TS tokens, D-386): a block is reported only where its copies still agree on most of their own identifiers and literals, or were renamed as they were pasted but kept most of their constants, and where the copies carry enough code to stand on their own or the copied extent reaches 30 lines — so a re-implementation sharing neither names nor values, and a small pasted declaration, are both found and deliberately not reported, and a clean R10 is not a claim that nothing was copied.

Method: Near-exact copy-pasted blocks of substantial extent across the frontend (the D4 clone algorithm run over JS/TS tokens). Masking finds the candidates; a block is reported when its copies still agree on most of their own identifiers and literals, or when a renamed copy still agrees on most of its constants, AND the copies carry enough code to stand on their own — or when the copied extent reaches 30 lines. So a re-implementation sharing neither names nor values, and a small pasted declaration, are deliberately not counted. Deterministic.

• 39 duplicated blocks under src/renderer/utils/musicSdk/ have copies in at least two of the sibling directories bd, kg, kw, mg, tx, wy — 33 of them are reported below, and 6 are counted here but not reported individually: those copies match on shape but no longer clear R10's bar for an individually reported row — either they kept neither their own names nor their values, or what was copied is too small to stand on its own (it reports near-exact duplication only, and only of substantial extent). What this row states is the concentration, which the detector measured over all 39 and which does not depend on how exactly each block's copies still match. That concentration is one structural fact, not 39 local ones: the siblings replicate behaviour none of them owns, which is the shape of a missing shared module — a common library every sibling imports — rather than 39 separate extractions.

• REDACTED:439 · REDACTED:498 — the two spans are one implementation copied and then locally edited — 1363 tokens are still identical, in the same order in both files, with only local edits between them. The copies have already begun to drift, which is this row's finding: an edit made to one and not the other changes behaviour silently. Diff the two spans first to learn what genuinely differs, then extract the shared core into one module both sites use, passing the differences in as parameters — or, if one copy exists only because the other could not be imported from its context, make one of them the single source the other is generated or re-exported from. If one copy is no longer reachable, delete it rather than letting it shadow the live one. — REDACTED:439

Pick one file as the single source and derive the others from it (re-export it, spread it into the local overrides each variant genuinely needs, or generate the copies at build time) — the few lines that differ between the files are exactly the part each variant should still own. Check first whether the copies are deliberately standalone deliverables (a translation file seeded from its sibling and waiting to be translated); where they are, the duplication is the design, and the honest move is to mark the seeded file as untranslated rather than to let it pass as done. — src/common/utils/request.ts:1

Where they turn out to be declarations, a literal's entries, or the cases of an enumeration, there is no call site to call anything from, and collapsing them would delete what each copy pins — a shared base type, a generated set, or one exported constant each site refers to is the move instead, and sometimes the honest answer is that there is nothing to extract at all.

What to do

• Act on each finding's own remediation rather than one rule: the move depends on what recurs. Where the copies are executable blocks, give the shared part one home and call it from each site; where they are declarations, a listing, a specialisation already delegating to its base, or one shape repeated per entity, there is no call site and the move is a shared type, a generated set or a factory — sometimes there is nothing to extract.

The two numbers answer different questions and the gap between them is what decides whether to act: cyclomatic counts the independent arms through the body, cognitive counts what it costs to hold them in your head, so nesting and mixed boolean chains raise it while a flat run of independent arms does not. Cognitive is at or above cyclomatic here, so the branching is nested or entangled rather than laid out side by side — extracting each decision into its own named function is the change that pays.

What to do

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

React / JS · Code Health — How many source files 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 each oversized file along the responsibilities already in it, into smaller focused modules in the same package.

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.

• 0% of 582 production file(s) reachable from 0 test file(s) via the import graph — 'production' here is the RESIDUE: every source file left once tests, tooling, generated output, config, declarations and declaration-only modules, fixture corpora, type fixtures, behaviour-free data modules, re-export barrels, registration/constant data modules and service workers are set aside, so the percentage is taken over a smaller denominator than the workspace's file count

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 D30 (JS/npm Dependency Vulnerabilities).

Method: npm dependency staleness from manifest/registry metadata (a maturity signal; JS/npm CVEs are scored separately in D30, which answers dependency vulnerabilities for every ecosystem). Deterministic.

What to do

• Bump outdated dependencies to current versions to limit upgrade debt.

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.

• test ✓ · lint ✓ · typecheck ✗ — read from this repository's package.json scripts and corroborated against its CI workflows. A script counts when its name or command matches the step: `test` for the suite, `lint` or `prettier` for linting, `typecheck`/`type-check`/`tsc` for type checking. ✗ therefore means no script or CI step under those names was found, NOT that the step is absent from your pipeline — a task invoked by a runner this check does not read, or named something else entirely, is not seen and is worth confirming before acting on a cross. A ✓ means the wiring is DECLARED — a script or CI step under those names exists. It is not a statement that the step passes, or that it runs at all: nothing here installs a dependency or executes a suite.

What to do

• Add `tsc --noEmit` as package.json scripts and run them in CI.

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.

• Unreachable from the 52 application, 60 tooling and 0 test entry point(s) detected in this repo. Gate removals on `npm run build` — an undetected custom entry would make these reachable.
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), and no other file in the scanned tree imports it — nothing in-repo names this module at all, which is the strongest form of this claim the import graph can make (×31) — REDACTED, src/renderer/utils/musicSdk/tx/singer.js, src/common/utils/request_node16.ts, …
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), but 3 in-repo import(s) from 3 other file(s) do name it (REDACTED, src/renderer/utils/musicSdk/kg/singer.js, REDACTED) — every one of those referrers is itself unreachable, so this file is dead only as a member of that cluster: if any referrer is in fact alive, this row falls with it — REDACTED
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), but 1 in-repo import(s) from 1 other file(s) do name it (REDACTED) — every one of those referrers is itself unreachable, so this file is dead only as a member of that cluster: if any referrer is in fact alive, this row falls with it — REDACTED
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), but 5 in-repo import(s) from 5 other file(s) do name it (publish/utils/compileAssets.js, publish/utils/copyFile.js, publish/utils/cos.js and 2 more) — every one of those referrers is itself unreachable, so this file is dead only as a member of that cluster: if any referrer is in fact alive, this row falls with it — publish/utils/index.js
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), but 1 in-repo import(s) from 1 other file(s) do name it (publish/index.js) — every one of those referrers is itself unreachable, so this file is dead only as a member of that cluster: if any referrer is in fact alive, this row falls with it (×2) — publish/utils/updateChangeLog.js, publish/utils/clearAssets.js
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), but 1 in-repo import(s) from 1 other file(s) do name it (publish/utils/updateChangeLog.js) — every one of those referrers is itself unreachable, so this file is dead only as a member of that cluster: if any referrer is in fact alive, this row falls with it — REDACTED
• no import path from any entry point (52 application, 60 tooling, 0 test roots considered), but 1 in-repo import(s) from 1 other file(s) do name it (publish/utils/cos.js) — every one of those referrers is itself unreachable, so this file is dead only as a member of that cluster: if any referrer is in fact alive, this row falls with it — publish/utils/cosConfig.js
• Nothing imports this binding — it is safe to review for removal. — src/common/utils/index.ts:8

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. — src/renderer-lyric/components/index.js:1

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.

• src/lang/i18n.ts → src/lang/index.ts → src/lang/i18n.ts — src/lang/i18n.ts
• src/main/app.ts → src/main/modules/winMain/index.ts → src/main/app.ts (one verified cycle inside a mutually-dependent group of 46 files) — src/main/app.ts
• src/renderer/core/player/action.ts → src/renderer/core/player/utils.ts → src/renderer/store/player/action.ts → src/renderer/core/player/index.ts → src/renderer/core/player/action.ts (one verified cycle inside a mutually-dependent group of 5 files) — src/renderer/core/player/action.ts
• src/renderer/store/index.ts → src/renderer/utils/musicSdk/index.js → src/renderer/utils/musicSdk/api-source.js → src/renderer/store/index.ts (one verified cycle inside a mutually-dependent group of 56 files) — src/renderer/store/index.ts
• src/renderer/store/list/action.ts → src/renderer/store/list/listManage/index.ts → src/renderer/store/list/listManage/rendererListManage.ts → src/renderer/store/list/listManage/action.ts → src/renderer/utils/data.ts → src/renderer/store/list/action.ts (one verified cycle inside a mutually-dependent group of 6 files) — src/renderer/store/list/action.ts

What to do

• Break each cycle by extracting the shared piece into a module both sides can import.
