amantinband/clean-architecture

Executive summary

amantinband/clean-architecture scores 57 out of 100, which would normally be rated Adequate, but it is rated Weak because its weakest group of dimensions, Explicit debt, is rated Critical. The standard never rates a score more than one step above its weakest group, so a high average can't hide a weak area. Watchdog judged it as a template, sample or demo, meant to be read or copied, so the dimensions about building, releasing and running a product don't apply, and its lenses are rated against a lower bar. The score itself is worked out as for any repository.

The weakest lens counts most in the score, and here that is Code Health, which scores 50 and is rated Adequate. Its Explicit Debt dimension scores 0 out of 10, and until that reaches 4, Code Health can't be rated higher than Adequate. The first actions are to resolve the 1 EmptyCatchBlock finding(s) in Explicit Debt and to resolve the 1 WriteOnlyPrivateField finding(s) in Explicit Debt, and if Code Health rose to 70, the score would rise from 57 to about 62.

44 findings are critical: 20 in Explicit Debt, nine in Secrets (history), seven in Static Analysis (SAST), six in Dependency Vulnerabilities, one in IaC & Container Security and one in Project dependency cycles.

The product code is 1,781 lines, which would take an estimated 0.1 person-years, around €6,700, to rebuild.

Code Health 50 Adequate, capped by Explicit Debt and Exception handling Architecture 88 ★ Exemplary Maturity 64 Adequate, capped by Knowledge Freshness Production Readiness 60 Adequate, capped by Library API & versioning Security and Compliance 70 Adequate, capped by Secrets (history) and Static Analysis (SAST) Domain Modelling 68 Adequate, capped by Strongly-typed ids Event-Driven 100 ★ Exemplary Performance 60 Strong

A lens is capped at Adequate while one of its dimensions scores below 4 out of 10, however well the rest of the lens does. That way a serious problem in one place always shows in the lens's rating.

How the score is built: what each lens counts for The lenses don't count equally. The weakest lens counts most, the next weakest a little less, and so on, so a weak area pulls the score down instead of being averaged away. In the bar below, each part's width shows how much that lens counts and its colour shows its rating. Improving the widest part moves the score most, and as that lens improves, it counts for less, because another lens becomes the weakest.

Watchdog compares every finding with the previous survey's. A finding that has only moved to another line in the same file counts as the same finding, so only new findings appear here. Advisory notes from the AI model are left out, because the model words them afresh in every survey.

Fixed since the last survey: 1 finding

This critical or serious finding was in the previous survey, on 7 October 2026, and is gone from this one.

Dependency direction · Dependency-rule violation: CleanArchitecture.Application.SubcutaneousTests (Application) → CleanArchitecture.Api (Web)

Rebuild cost: about €6,700 · Estimate

Cost to rebuild	€2,200 to €11,000, for 37 to 118 hours of work, about 0.1 person-years for one engineer
Difficulty of the problem	Very high, judged from the kind of software and how it is built. Code that solves a harder problem, such as payments or medical bookings, costs more per line to write.
Quality factor	×0.8 at a score of 57. Better code takes more work to write, so the factor is ×1.0 at a score of 70, lower below it and higher above it.
Size	Very small: 1,781 lines of product code, of which 53% is declarations and boilerplate, 31% straight logic and 16% logic with branches

How the estimate is made: Watchdog prices the hours a team would need to write this code again, at €60 to €95 an hour. Declarations and boilerplate are priced at a fast rate and logic at a slower one, and the logic is then multiplied by the difficulty of the problem and by the quality factor. The estimate can be about 30% off either way, and it moves most with the hourly rate and the difficulty.

Diagnosis: what the measurements show together

Each conclusion below combines several dimensions into one point that no single dimension shows, and lists the measurements it rests on.

One cause behind 6 Domain Modelling findings · Common cause

6 findings in the Domain Modelling lens come from the same cause. The code models the business as objects, such as an order or a customer, and each object should guard its own rules: an order, for example, should refuse to be shipped before it has been paid. Here the objects don't do that. Some objects only hold data, while the rules that should keep that data valid sit elsewhere in the code. Identifiers, such as order numbers and customer numbers, are passed around as plain numbers or text, so nothing stops the code from using one kind where another belongs. Because all of these findings have the same cause, fixing it once, in the business objects themselves, deals with them together.

Based on: Rich vs anemic model (1 finding) · Strongly-typed ids (5 findings)

What to do: Give each business object the methods that enforce its rules, such as a method for shipping an order that first checks it has been paid, and let only those methods change its data. Give each kind of identifier a type of its own, so an order number can't be used where a customer number belongs.

If you do one thing first · First action

Resolve the 1 EmptyCatchBlock finding(s) in Explicit Debt. Of all the actions in this report, it raises the score most for the work it takes: about 5 points for low effort, because it clears the 1 Explicit Debt findings. The next survey will show the change in the score.

Architecture — module dependency graph

Project dependencies, layered top-to-bottom; arrows show direction. Any dashed red edge points upward or sideways — a layering smell or cycle. A clean layered graph has none.

Architecture: which parts of the code depend on which

The code is divided into modules, groups of code that each handle one part of the product, and a module depends on another when it uses code from it. The table lists the modules both down the side and across the top, in an order where each module should only use modules listed above it. A number in a cell means the module on that row uses the module in that column, and it counts the pairs of building blocks (types) that connect them. The one thing to look for is a mark above the diagonal line. It means two or more modules use each other in a loop (a dependency cycle), so none of them can be changed, tested or released on its own.

51 modules, with 91 dependencies between them. One loop runs through 2 of the modules, marked above the diagonal.

The table shows the 40 modules with the most connections; 11 more are left out to keep it readable.

Which modules use which. The module on each row uses the module in each column, and the number counts the pairs of types that connect them. A cell above the diagonal is part of a loop.

Roadmap

Begin by addressing the 18 explicit debt findings, starting with the .editorconfig file, followed by resolving the empty catch block in EventualConsistencyMiddleware.cs and the write-only private field in CreateSubscription.ValidationTests.cs. Next, fix the swallowed exception to ensure proper error visibility. Finally, correct the async void method in SendEmailNotifications to improve application stability and correctness.

Ranked by impact ÷ effort. "Helps" is the estimated gain on the 0–100 health score.

How the grades work

Every finding carries one of four grades. Three say how serious it is. The fourth says this survey could not settle it — and it is a grade, not a gap.

Critical — 44

A definite problem that already costs you something and drags the score down: a missing authorisation check, a dependency with a known exploit, a build that does not reproduce. Failure here tends to cause failures elsewhere.

Serious — 95

Likely wrong, but not failing yet. It degrades the codebase over a longer horizon and can cause failures elsewhere — not urgent this week, not something to carry for two years either.

Minor — 64

Recorded, with no effect on how the codebase functions. Present so the survey is complete, not because it needs doing.

Could not be resolved — 3

Something this survey could not settle from the outside, and which could be critical or serious. Either a control was required and no positive evidence of it exists in the repository — a backup job that nothing shows was ever restored from proves nothing about restores — or our own analysis could not run over that part of the tree. This is not a clean result. These are excluded from the score rather than awarded a pass, so the number on the cover neither rewards nor penalises them: if you act on this survey without resolving them, you carry that risk yourself. Each one is named under Limitations.

Methodology & how to trust this report

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. 92 of 98 evaluated dimensions are computed purely by tools and static analysis (confidence 1.0); 6 documentation/naming judgement(s) are LLM-assisted and labelled advisory. Overall confidence is 1.0 — 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 — 98 dimensions across the health lenses

D1D2D3D4D5D6D8D9D10D11D12D13D14D15D17D18D19D21D22D24D26D27D28D29D30D31D34D35D39D44AX1AX10AX2AX3AX4AX5AX6AX8AX9C2C3C4DM1DM10DM11DM12DM2DM4DM5DM6DM7DM8DM9ED1ED2ED3ED4ED5GD1IC1M1M2M3M4P1P10P4P8P9PF1PF2PF3S1X1X12X13X14X15X16X17X18X19X2X20X21X22X23X24X25X26X27X28X29X3X30X32X4X5

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, 144 of 203 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.

Run transparency — what happened this run

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.

D16 Bus Factor — not measured this run — This is a true statement about the repository that carries nothing for its owner to act on, so it is reported here rather than as a defect in their code. Single-maintainer repository — bus factor is not applicable (5 contributor(s) across 67 commit(s) sampled, automation and bot accounts excluded). One of them holds 93% of the history; the other 4 hold 1.8% each on average, below the 5% at which there is somebody to hand the work to. That is a single maintainer with drive-by contributors, not a team whose knowledge has concentrated — so the bus factor is not applicable and there is nothing here for the owner to act on.
D32 Data Compliance (PII/GDPR) — not measured this run — Watchdog could not measure this here. That is a gap on our side — a collector, parser or image we have not built yet — and it is neither a defect in this repository nor evidence that the check would have passed. `src/CleanArchitecture.Api/Controllers/RemindersController.cs`, `src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs`, `REDACTED`, `src/CleanArchitecture.Application/Common/Behaviors/AuthorizationBehavior.cs`, `src/CleanArchitecture.Application/Common/Behaviors/ValidationBehavior.cs`, … (+25 more) produced a parse error, so every rule in this engine's `gdpr.yml` was absent there. That absence is NOT a clean result: these rules detect personal data crossing a boundary into a log sink, a URL or browser storage, and a file that was never parsed cannot report any of the three. The rest of the tree analysed normally and its rows above stand; only these files are unaccounted for. You can widen what we reach: fix the syntax error (or exclude the file deliberately) and re-scan to cover it.
PF3 Async & latency hygiene — measured, with a gap in what it reached — Watchdog measured this, but not all of it. What it did not reach is a gap on our side — a collector, parser or image we have not built yet — so the numbers on that dimension cover less than the repository, and the part left out is not evidence that it would have passed. 23 further occurrence(s) are not listed individually; the score already reflects all 63.

Repo exclusion declarations: 1 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 — an in-process token-stream comparison over sliding windows, with type-aware normalization — so 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.
D5 Coupling: Coupling is measured between projects/assemblies — runtime coupling through DI, reflection, messaging or shared databases is invisible to a static reference graph.
D6 Cohesion (LCOM4): LCOM4 cohesion is syntactic — it infers connectivity from which methods touch which fields/methods by name, not from real runtime behaviour or intent.
D8 Code Coverage: Coverage is measured by building and running the test suite inside Watchdog's isolated image — the target repo is never modified, and nothing on your systems runs. So coverage exists only when the suite builds and runs within the inline time budget; one that needs external services, can't build, or exceeds the budget yields no coverage (D8 then degrades to not-measured, not a low score). Line coverage also says nothing about assertion quality.
D9 Test Distribution: The test-pyramid shape is inferred from project/folder naming and references, with a single test host bucketed per-file by its path tier and content signals — a suite that names tiers unconventionally and gives no per-file signal can still be mis-bucketed.
D10 Test Quality: Assertion density is structural — it cannot tell a meaningful behavioural assertion from a trivial one, only that an assertion is present.
D11 Test Reliability: Flakiness is inferred from history/markers — Watchdog runs the suite once (for coverage), not the repeated runs under varied conditions that reveal nondeterminism, so a flaky test never recorded as failing is invisible here.
D12 Dependency Hygiene: Dependency health reads manifests and lockfiles — a vulnerability in a vendored/copied dependency, or risk from how a dependency is actually used, is outside this view.
D13 REDACTED Scanning: REDACTED 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").
D14 License Compliance: License compatibility is checked against declared package metadata and a policy — mislabelled or missing license metadata, and obligations that depend on how you distribute, are not resolved here.
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.
D17 Explicit Debt: Acknowledged-debt signals (TODO/FIXME, suppressions, dead code) are textual — undocumented debt that nobody marked, and debt that lives in design rather than annotations, is invisible. Committed machine-written code (scaffolded migrations, designer/codegen output, generated stubs) is excluded — it is never the team's dead code to delete.
D18 Solution Shape: Build integrity reflects whether the solution compiled in this environment — a build that needs a private feed, a specific SDK, or a generated file absent from the repo can read as broken when it is merely unreproducible here.
D19 Documentation Quality: Documentation quality is judged by an LLM over a bounded sample of docs — it reads what is written, not whether the docs match the running system, and it is advisory, not a measurement. Its critique rows are drawn from a closed category vocabulary and each row means the same thing in every run, so two scans can be compared row by row; the SET that fires is still a sample, and does not repeat exactly. Measured on one frozen input, six scans at one engine SHA: 2-5 critique rows per scan, 8 distinct rows across the six, 3 of those 8 seen in only one scan. So a D19 row is evidence about the documentation, but a COUNT of D19 rows is not a quantity — never read a change in it as an improvement or a regression.
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.
D22 Internal API Consistency: API-surface coherence is an LLM judgement over a sample of the public surface — consistency of intent across the whole API is approximated, not exhaustively verified.
D24 Comment Value: Comment value (WHY vs WHAT) is an LLM judgement over a bounded sample — it is advisory and cannot weigh a comment against the precise code change it was written to explain.
D26 Project Cohesion: Project focus is sized from members/namespaces per project — a project that is broad by deliberate design reads the same as one that has sprawled.
D27 Navigability: Indirection/navigability is structural — it measures hops to follow a call, not whether that indirection buys real flexibility or just ceremony.
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").
D30 Dependency Vulnerabilities: CVE matching depends on accurate package/version metadata and on the advisory databases — a vulnerability with no published advisory, or in code not declared as a dependency, is not seen. Coverage needs a RESOLVED graph: an unpinned requirements.txt, or a pom without a resolved build, yields partial coverage rather than a clean verdict. An ecosystem the analyzer cannot scan is reported as unmeasured, never as clean.
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.
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.
D44 Platform End-of-Life: The support table is FROZEN, so it goes out of date by losing RECALL: a release that ended support after the table was written is missed until the table is refreshed, and this dimension reading 10 is not evidence that a platform is current. Only platforms the repository DECLARES in a place this pass reads are seen — a runtime named only in a REDACTED (D31's subject), in a CI workflow (D29's), or in a file this pass does not parse (go.mod, a Gemfile ruby directive) is invisible here, which is why a repository declaring none of them abstains rather than scoring. Only frameworks with a PUBLISHED support policy are tracked: React, Flask and Express publish none, so their age cannot be judged and their absence from a report is not a statement that they are supported.
AX10 Code composition: Role is inferred from namespace/folder convention, not semantics — a domain concept living in a folder named "Services" reads as application, and the split is lines-of-code, not business value. The business-logic-share score is a SOFT, FLOORED signal: it contributes to the Architecture lens but is floored at the Critical gate, so an infrastructure-heavy design (a gateway, an ETL, a driver) is legitimately low without being nuked to zero.
AX9 CQS / query purity: Handlers are found by interface/name convention — a query handler using neither is not seen. Mutation is a resolved write/publish invocation (SaveChanges/repository/bus), so a write hidden behind a hand-rolled wrapper, reflection, or a string-keyed service locator resolves to a non-persistence type and isn't flagged; it detects that a query writes state, not whether the write is a legitimate read-side cache update. Clean means "no resolved write/publish in a query body", not a proof of CQS purity.
C3 Audit Trail: This control is scored from in-repo evidence only — a working control configured outside the repository leaves no signal a static scan can credit.
C4 Data Retention: This control is scored from in-repo evidence only — its real-world effectiveness, exercised only at runtime, is outside a static scan.
DM4 Rich vs anemic model: Behaviour is detected as state mutation inside a method body — a method that enforces an invariant by validating-and-throwing without mutating reads as a query, and mutation delegated through an interface the scan can't resolve isn't credited; entities with zero public properties still drop out of the population. It detects that state changes, not whether the rule is correct.
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.
ED5 Idempotency: Idempotency is judged from the handler body's visible writes and guards — a guard enforced by a database unique constraint, a broker's exactly-once delivery, or a domain method whose no-op-when-applied logic the scan can't follow may read as at-risk; the at-risk candidates are confirmed by a SAMPLED LLM verdict (advisory, not exhaustive) and degrade to heuristic-only when no model is configured. It flags the at-least-once double-apply SHAPE, not a runtime proof of a duplicate effect.
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".

The LLM boundary

LLM-set scores this run (6): D19, D21, D22, D24, ED5, M4 (model: Local LLM). For these, a model reads a bounded sample and sets the numeric score; each names its own sample and method on its card. They 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.

D27 · Navigability9.5 / 10Exemplary✓ Tool-verified

What it measures: How far you must trace to follow a call — low indirection and co-located slices read easier.

Method: Call indirection (interface hops, cross-namespace calls, slice-locality scaled) over a sampled set of method invocations, size-aware baseline. Sampled; confidence discounted by symbol-resolution gaps. C# also names each pass-through layer (a class whose every public method only forwards its own parameters to one collaborator) as a located finding; the score is not affected.

Coverage: Slice locality from the first namespace segments, SAMPLED (≤400 methods) — not exhaustive.

Maturity: Documented → Verified → Prevented · effective 9.5 / 10 · rule-coverage 100% · ceiling Documented

96 % of calls cross a namespace and 11 % go through an interface, but 100 % of collaborators are co-located — so a call's collaborators sit together and tracing stays easy. Baseline: small — navigation cost is tolerated.

Method: REDACTED scan via TWO gitleaks detect passes in an isolated checkout — the full git history, then a second --no-git pass over the working tree as it stands — merged and de-duplicated by (rule, file, line); each match flagged High. Both invocations are recorded in the audit trail. Exhaustive; when the tool is absent, or when its output cannot be parsed into the expected shape, the dimension is WITHHELD as an explicit measurement gap on our side — unscored and excluded from the lens, never a hedged middling score.

D29 · Static Analysis (SAST)2.5 / 10Weak✓ Tool-verified

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

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

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

Maturity: Documented → Verified → Prevented · effective 2.5 / 10 · rule-coverage 100% · ceiling Documented

10 finding(s): 0 critical, 7 high, 3 medium, 0 low. semgrep hit a parse error in 30 file(s) — `src/CleanArchitecture.Api/Controllers/RemindersController.cs` (line 16), `src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs` (line 17), `REDACTED` (line 17), `src/CleanArchitecture.Application/Common/Behaviors/AuthorizationBehavior.cs` (lines 12–13), `src/CleanArchitecture.Application/Common/Behaviors/ValidationBehavior.cs` (line 9), … (+25 more) — so no absence of findings in the named regions is evidence of anything; rows reported elsewhere in those files are real. Fix the syntax error (or exclude the file deliberately) and re-scan to cover them. In 30 of those file(s) — `src/CleanArchitecture.Api/Controllers/RemindersController.cs`, `src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs`, `REDACTED`, `src/CleanArchitecture.Application/Common/Behaviors/AuthorizationBehavior.cs`, `src/CleanArchitecture.Application/Common/Behaviors/ValidationBehavior.cs`, … (+25 more) — the break is a C# primary constructor, which semgrep's grammar cannot parse and which hides the type from every rule scoped to it; those files were re-scanned from a shadow copy with the constructor's parameter list blanked (line and column preserving), which restores the type to the rules, and 0 additional row(s) came from that pass.

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 (and Erlang, whose `rebar.lock` syft first converts to a CycloneDX SBOM the scanner reads, with rows attributed back to the lock), Go, Java and Kotlin via Maven/Gradle (and Scala, whose sbt build's pinned direct declarations are written into a CycloneDX SBOM the scanner reads, with rows attributed back to the build file), 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)`. NotApplicable only when NO ecosystem is readable; if any applicable ecosystem could not be scanned the findings are REPORTED and the score is withheld.

D35 · Change Coupling10.0 / 10Exemplary✓ Tool-verified

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.

D44 · Platform End-of-Life10.0 / 10Exemplary✓ Tool-verified

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.

Maturity: Documented → Verified → Prevented · effective 10.0 / 10 · rule-coverage 100% · ceiling Documented

0 end-of-life runtime(s) and 0 end-of-life framework(s), read from 3 platform declaration(s) and 0 dependency declaration(s). This dimension reads what the repository says about ITSELF — a pinned target framework, a version file, a capped requires-python, a Rust toolchain pin, a framework major a constraint cannot move off. 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.

AX10 · Code composition5.8 / 10Adequate✓ Tool-verified

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.

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.

AX3 · Project dependency cycles10.0 / 10Exemplary✓ Tool-verified

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.

The namespaces CleanArchitecture.Domain.Subscriptions ↔ CleanArchitecture.Domain.Users depend on each other. The lightest dependency in the cycle is CleanArchitecture.Domain.Subscriptions → CleanArchitecture.Domain.Users (CleanArchitecture.Domain.Subscriptions.Subscription → CleanArchitecture.Domain.Users.SubscriptionType, 1 type pair(s)); cut that one first, e.g. by moving the shared type to a namespace both can use or inverting it behind an interface. — src/CleanArchitecture.Domain/Users/Subscription.cs:2

Method: Roslyn scan: public interface declared-member counts (accessors fold into their property/event); fat-interface threshold (over 15 declared members) flagged per type. Each finding also reports the distinct-OPERATION count — members counted by name, so an overload group counts once — which decides whether it states the caller-side ISP harm or the implementer-side burden of an overload set. TypeScript: exported interfaces that declare behaviour, counted over their REQUIRED operations (method signatures and function-typed properties with no `?`, once per signature) — data-shape interfaces and ambient .d.ts declarations are outside the population; JavaScript declares no interfaces and is not applicable.

AX9 · CQS / query purity10.0 / 10Exemplary✓ Tool-verified

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

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

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

DM10 · One transaction, one aggregate10.0 / 10Exemplary○ Nothing flagged

Other · Domain Modelling — Whether a single operation mutates more than one aggregate root. An aggregate is a consistency boundary, so saving two together fuses them into one — the second's invariants come to depend on the first's transaction, and the pair can no longer be separated. Reads of other aggregates are not counted.

Method: Neutral body surface (DDD-gated): every method body scanned for repository WRITE calls (Add/Update/Save/Remove/Delete/Insert/Store and their async forms), keyed on the ARGUMENT type rather than the repository type — three `IRepository<T>` writes collapse to one repository but are three distinct aggregates. Reads (Get/Find/Load/Query) are excluded, so loading another aggregate for context never counts. Score is offending methods over methods that write at all. Deterministic.

DM11 · Constructible invalid state5.3 / 10Adequate✓ Tool-verified

Other · Domain Modelling — Whether an aggregate can be constructed in a state its own rules forbid — a public constructor that takes a raw primitive, stores it, and validates nothing, with no factory beside it. A constructor taking only value objects is not counted: each parameter has already validated itself.

Method: Neutral surface (DDD-gated): each non-abstract entity/aggregate checked for a PUBLIC constructor taking at least one RAW PRIMITIVE parameter whose body contains no guard token (throw / Guard. / Ensure. / ArgumentException / CheckRule), on a type that also offers no static Create/Of/From/New factory. A constructor taking only value objects is never charged -- measured: 64 of 87 unguarded public constructors on the C# corpus take value objects only, so ignoring parameter types would be 73% false positives. One finding per entity. Deterministic.

`Reminder`'s public constructor takes `text` as raw primitives, and neither of the two things that would make that safe was found. What was searched, so you can tell an absence from a miss: for VALIDATION, the constructor body was scanned for `throw`, `Guard.`, `Ensure.`, `ArgumentNullException`, `ArgumentException`, `CheckRule` or `Requires.` — a guard reached through a helper method those tokens do not name is not seen; for a FACTORY, only this type's OWN static members were read, and only names beginning `Create`, `Of`, `From`, `New` or `Build` — one inherited from a base type, one on a companion builder, or one called `Parse`, `Make` or `Rehydrate` is not seen. If either exists, this row is wrong. If neither does, a caller can build a `Reminder` that breaks the rules it exists to enforce, and every rule downstream then has to cope with a state the model said was impossible. Guard in the constructor, take value objects that validate themselves, or make the constructor private behind a `Create` that can refuse. — src/CleanArchitecture.Domain/Reminders/Reminder.cs:21
`User`'s public constructor takes `firstName`, `lastName`, `email` as raw primitives, and neither of the two things that would make that safe was found. What was searched, so you can tell an absence from a miss: for VALIDATION, the constructor body was scanned for `throw`, `Guard.`, `Ensure.`, `ArgumentNullException`, `ArgumentException`, `CheckRule` or `Requires.` — a guard reached through a helper method those tokens do not name is not seen; for a FACTORY, only this type's OWN static members were read, and only names beginning `Create`, `Of`, `From`, `New` or `Build` — one inherited from a base type, one on a companion builder, or one called `Parse`, `Make` or `Rehydrate` is not seen. If either exists, this row is wrong. If neither does, a caller can build a `User` that breaks the rules it exists to enforce, and every rule downstream then has to cope with a state the model said was impossible.

DM12 · Ambient inputs in the domain10.0 / 10Exemplary○ Nothing flagged

Other · Domain Modelling — Whether domain types receive the time and randomness their rules depend on, rather than reading the process clock or a global random source directly — an ambient read makes the rule it feeds untestable at the instant that matters and lets two reads inside one operation disagree.

Method: Roslyn (DDD-gated, C#/VB only): domain-layer types scanned for ambient reads — DateTime/DateTimeOffset.Now/UtcNow/Today, Random.Shared, new Random(), Stopwatch.GetTimestamp — resolved against the semantic model, with a comment/string-stripped token fallback only where resolution fails.

An id wrapper is recognised by VALUE SEMANTICS, not by being a struct — a record struct, a record class (`record ApartmentId(Guid Value)`) or a class declared by a typed-id base (`class MemberId : TypedIdValueBase`) all count, while a plain mutable class (reference equality) and a verb-phrase query record (`GetCustomerById`) do not. Deterministic, adoption percentage.

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

`Reminder.UserId` is a raw `Guid` — give it a strongly-typed id: a dedicated single-field type wrapping the `Guid`, in whatever form your language spells that. — src/CleanArchitecture.Domain/Reminders/Reminder.cs:9
`Reminder.SubscriptionId` is a raw `Guid` — give it a strongly-typed id: a dedicated single-field type wrapping the `Guid`, in whatever form your language spells that. — src/CleanArchitecture.Domain/Reminders/Reminder.cs:11
`ReminderDeletedEvent.ReminderId` is a raw `Guid` — give it a strongly-typed id: a dedicated single-field type wrapping the `Guid`, in whatever form your language spells that. — src/CleanArchitecture.Domain/Users/Events/ReminderDeletedEvent.cs:5
`ReminderDismissedEvent.ReminderId` is a raw `Guid` — give it a strongly-typed id: a dedicated single-field type wrapping the `Guid`, in whatever form your language spells that. — src/CleanArchitecture.Domain/Users/Events/ReminderDismissedEvent.cs:5
`SubscriptionCanceledEvent.SubscriptionId` is a raw `Guid` — give it a strongly-typed id: a dedicated single-field type wrapping the `Guid`, in whatever form your language spells that. — src/CleanArchitecture.Domain/Users/Events/SubscriptionCanceledEvent.cs:5

What to do

Adopt strongly-typed ids across the domain — finish the migration or document the boundary; primitive ids invite transposed-argument bugs.

DM4 · Rich vs anemic model7.7 / 10Strong✓ Tool-verified

Other · Domain Modelling — Whether aggregates/entities carry the behaviour that protects their invariants, rather than being data bags driven by external services.

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

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

`Subscription` is an aggregate/entity with 1 data propert(ies) but no state-changing behaviour (only data and queries) — the business logic lives in a service. — src/CleanArchitecture.Domain/Users/Subscription.cs:6

What to do

Move business rules onto the aggregates/entities they govern so invariants are enforced at the source, not in anemic services.

DM5 · Encapsulated state10.0 / 10Exemplary✓ Tool-verified

Other · Domain Modelling — Whether entities protect their state — private/init-only setters, and collections handed out as read-only views rather than the mutable backing collection — instead of exposing writable state that bypasses invariants. Softened when a rehydration framework (Marten/EF) is present.

Method: Roslyn (DDD-gated): entities scanned for publicly writable state — public setters, and (C#/VB) own mutable collections handed out through an auto-property, a public field or a bare-field expression getter, where a computed/copying getter is never charged. One finding per entity; score softened when Marten/EF rehydration frameworks present. Deterministic, framework-aware.

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

DM6 · Domain ↔ infrastructure boundary10.0 / 10Exemplary✓ Tool-verified

Other · Domain Modelling — Whether the domain layer stays free of infrastructure dependencies (EF/Marten/HTTP/ASP.NET) — 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.

DM7 · Repository granularity10.0 / 10Exemplary✓ Tool-verified

Other · Domain Modelling — Whether repositories are per aggregate root (not per child entity) and keep the persistence query handle behind the contract, so the root's invariants can't be bypassed.

Method: Roslyn (DDD-gated): repository abstraction detection; repositories over non-aggregate-root entities flagged, and (C#/VB) repository INTERFACES whose members return a live persistence query handle (IQueryable/DbSet/IMongoQueryable) — implementations and specification evaluators are out of population by design, since composing a query internally is what an implementation is for. Deterministic, DDD-native.

Coverage: Population: repositories + aggregate roots by NAME convention; per-root repository rule checked within the set.

DM9 · Scattered domain decisions10.0 / 10Exemplary✓ Tool-verified

Other · Domain Modelling — Whether one domain rule is decided — or one measurement produced — in more than one place, rather than living on the type that owns it.

Method: Neutral body surface plus Roslyn (DDD-gated), two arms. DECISION (Roslyn only): a predicate over a domain type's members judged in two or more types, where none of those decisions live on the owning type — operands of comparisons and relational property patterns only, so a member merely passed as an argument is not judged. DERIVATION: a plain all-numeric carrier of ≥2 members, with no base type and exactly one constructor, CONSTRUCTED as the result of a method (returned or assigned, never inline as an argument) in two or more types other than its own — the same measurement produced twice, which centralising the judgement does not fix. DERIVATION runs on every language whose frontend declares the produced-or-passed fact per construction (Roslyn and the Java sidecar today); a target with only the derivation arm carries an engine gap naming the decision arm as not assessed, and a frontend that declares nothing keeps the dimension not measured rather than clean. Single-member rules, test code and generated code are out of population for both. Advisory.

ED5 · Idempotency8.4 / 10Exemplary◐ Sampled · advisory

Other · Readiness — Whether retry-prone mutations (command handlers + message/event consumers) are idempotent so an at-least-once redelivery or client retry doesn't double-apply the effect — heuristic at-risk detection confirmed by language model, advisory.

Method: Roslyn heuristic (any mutation, ungated): command handlers and message/event consumers that mutate persistent state without a visible idempotency guard (exists/dedup check, upsert, idempotency-key/inbox, conditional/versioned write, fixed-value set) flagged as at-risk; each at-risk candidate then confirmed or cleared by a language model as genuinely non-idempotent versus naturally-idempotent. Advisory without a model (heuristic-only, degraded), per-candidate judged with one.

Coverage: Population: retry-prone mutations — command handlers (CQRS write side) + message/event consumers (IConsumer/I*EventHandler) — that mutate persistent state; runs on any repo with mutations, not only event-driven ones. The at-risk subset (no obvious guard) is a HEURISTIC candidate set, each then LLM-JUDGED non-idempotent vs safe; a handler outside those conventions, or a guard the LLM can't confirm, is bounded by the sample. Degrades to heuristic-only when no model is configured.

`Events.ReminderDeletedEventHandler.Handle` mutates persistent state (a repository write) with no idempotency guard, and the model confirms a re-run would double-apply it. A retry or at-least-once redelivery means it can run twice — add an exists/dedup check, an upsert, an idempotency-key/inbox, or a versioned write. — src/CleanArchitecture.Application/Reminders/Events/ReminderDeletedEventHandler.cs:10
`Events.SubscriptionCanceledEventHandler.Handle` mutates persistent state (a repository write) with no idempotency guard, and the model confirms a re-run would double-apply it. A retry or at-least-once redelivery means it can run twice — add an exists/dedup check, an upsert, an idempotency-key/inbox, or a versioned write. — src/CleanArchitecture.Application/Subscriptions/Events/SubscriptionCanceledEventHandler.cs:11

What to do

Make retry-prone mutations idempotent — guard each write with an exists/dedup check, an upsert, an idempotency-key/inbox, or a versioned write, so a re-run doesn't double-apply.

GD1 · Unfinished & placeholder code10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Unreviewed-generation residue: shipped members still throwing NotImplementedException, and placeholder string literals left in non-test, non-generated code. Scored as a quality signature, never as a claim about authorship.

Method: Roslyn syntax scan: NotImplementedException throws and placeholder string literals in non-test, non-generated shipped code. Deterministic, code-shape signature.

Do you agree with this assessment?

IC1 · Incompleteness & stubs10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Unfinished work detected by code SHAPE, not keywords: members that only throw a "not implemented" exception, methods that take inputs and return a constant, async methods that never await, dead `if (false)` / `#if false` branches, and skeleton types most of whose members are holes. A real, objective slice of technical debt.

Method: Roslyn syntax scan: incompleteness by code shape (constant-returning methods, async-never-await, #if false branches, guards that return what the code already falls through to, tests an earlier guard already decided, comparisons against NaN, skeleton types), not keyword-gated. Deterministic, code-shape heuristic.

M1 · Documentation (README)8.0 / 10Exemplary✓ Tool-verified

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 README to the 10 of 10 project(s) that lack one — worth up to 2 pts.

Do you agree with this assessment?

M2 · Architecture documentation5.0 / 10Adequate✓ Tool-verified

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.

What to do

Record your significant design decisions. Write one short document per decision, giving its date, the situation, the decision and its consequences, and keep them together with your other design documents. A docs/adr folder with each file named by number and title is the easiest place to find them.

P10 · Library API & versioning2.0 / 10Weak✓ Tool-verified

Readiness · Readiness — For a library: a deliberate (small) public API surface and explicit semantic versioning so consumers can depend on it safely.

Method: Roslyn scan: public API surface area and semantic-versioning markers (SemVer attributes, changelog entries) for libraries; off .NET, a library is the ecosystem's publication act (an npm package that is not private and names an entry point, a PyPI distribution with a build system, a Rust library crate, a Maven/Gradle module that publishes, a Go module with no package main, a gemspec, a Composer library, a SwiftPM library product, a pub.dev or Hex package), its surface is the share of types the language model records as public (Rust, Swift, Java, Kotlin, Go, Dart; not measured where the model records no type visibility or, as in TypeScript, only module-level export), and its version is read from the manifest, a semver CHANGELOG, release tooling or semver git tags. Exhaustive, deterministic.

13/14 types (93%) are public. For a library, every public type is a stability contract — make internal-by-default and expose only the intended API.
No explicit version was found by any of the six routes this check reads: a `<Version>` or `<VersionPrefix>` property; a `GitVersion` or `MinVer` reference; the split Arcade spelling (`<MajorVersion>` AND `<MinorVersion>` together); a hand-written `[assembly: AssemblyVersion]` in source, with `bin/` and `obj/` excluded so the SDK's generated AssemblyInfo cannot satisfy it; or a version handed to MSBuild by the pipeline, as `-p:Version=` / `-p:PackageVersion=` on a `dotnet build` or `dotnet pack` line. Only project files, first-party source and CI files are read, so a version computed somewhere none of those can see is invisible here. A published library needs explicit semantic versioning so consumers can reason about breaking changes.

What to do

Make types internal by default; expose only the deliberate public API so internals can change without breaking consumers.
Stamp a semantic version (csproj <Version> or GitVersion/MinVer) and follow semver for breaking changes.

P4 · Deployment & Rollback5.0 / 10Adequate✓ Tool-verified

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.

Deployment is orchestrated by compose, but no service declares a `healthcheck:` and nothing pins a previous image to fall back to — the runtime can tell that the container is up, not that it is serving, so a bad release is harder to detect and reverse.
Deployment is automated and no gate that pauses it for a human is DECLARED IN THIS REPOSITORY'S PIPELINE FILES. What was read: every file under `.github/workflows/`, `.forgejo/workflows/`, `.gitea/workflows/`, `.azuredevops/` and `.azure-pipelines/`, plus `.gitlab-ci*` and `azure-pipelines*` — with comment text stripped, so documenting a gate is not declaring one. What would have counted: GitLab's `when: manual`, CircleCI's `type: approval`, an Azure `ManualValidation@` task or an `approvals:` block, a Jenkins `input` step, a `uses:` step naming an approval action, an `environment:` paired with `reviewers` / `required_reviewers` / `protection` / `wait-timer` / `deployment_branch_policy`, a draft-release step, a `workflow_dispatch` promotion, or a release-event gate. ★ What this cannot see, because none of it is a file: a GitHub environment whose required reviewers are configured in repo SETTINGS, a branch protection rule, or an organisation deployment policy — all of them real, enforced gates that live outside the repository. If yours is one of those, this row is wrong and nothing in the tree could have told us. Otherwise: whatever reaches the release trigger goes to production unreviewed, so a mistaken merge or tag is live before anyone can stop it.

What to do

Add a `healthcheck:` to the served compose service — probing the endpoint it already answers on where it has one — with `depends_on: condition: service_healthy` on whatever waits for it, and keep the deployed image tag immutable and recorded so rolling back is re-pointing at the previous tag rather than rebuilding.
Add an approval/environment gate (required reviewers / protection rules) before production promotion.

P9 · Domain vs controller coverage8.5 / 10Exemplary✓ Tool-verified

Readiness · Readiness — Whether test coverage concentrates on the domain (business rules) rather than the trivial web/controller layer — a focus check a generic tool can't make.

Method: Roslyn plus test-execution analysis: domain-layer versus trivial web/controller coverage ratio. Computed metric, deterministic.

What to do

Raise domain coverage toward 100% — cover the remaining aggregates / value objects / domain services where the business invariants and costly bugs live.

Do you agree with this assessment?

PF1 · Benchmark discipline6.0 / 10Strong✓ Tool-verified

Readiness · Performance — Whether the code protects its performance with benchmarks — a benchmark suite, allocation/memory measurement, and (ideally) a CI gate. Presence is credited as a bonus, never a deduction.

Method: Repo + source scan: BenchmarkDotNet referenced (csproj/source), [Benchmark]/[MemoryDiagnoser] attribute counts, and a benchmark step in CI; off .NET, the same ladder over Go testing.B, Rust criterion/#[bench]/divan, JMH/kotlinx-benchmark, pytest-benchmark/asv/pyperf, tinybench/mitata/vitest bench/benchmark.js and Swift package-benchmark — scored as a bonus ladder (absence is neutral, never a deduction). Deterministic, presence detection.

No benchmark suite was found by the two searches this check runs. FIRST, a BenchmarkDotNet package reference in any project file — every project the workspace loaded, plus a walk of project files on disk that never loaded, because a benchmark suite is exactly the project a partial load drops. SECOND, a script harness: a file whose name contains `benchmark` and ends `.py`, `.sh`, `.ps1`, `.bash`, `.rb`, `.js` or `.mjs`, credited ONLY when this repository's CI text also mentions benchmarks — a harness no pipeline runs is read as a fixture, deliberately. Neither search can see a benchmark suite in another ecosystem's idiom (a Go `testing.B` file, a JMH or criterion project, a pytest-benchmark run), so this is 'no benchmark found by those two searches', not a verdict that the repository has none. Where code is performance-sensitive, a benchmark guards against silent regressions — but it's a bonus here, not a deduction.

What to do

Add a benchmarking harness for the hot paths and run it in CI to catch regressions (for .NET, a BenchmarkDotNet project with [MemoryDiagnoser] to track allocations).

Do you agree with this assessment?

PF2 · Allocation hygiene6.0 / 10Strong✓ Tool-verified

Readiness · Performance — Whether the code is written to minimise allocations so it doesn't pressure its host's memory manager — buffer/slice views over copies, object pooling, stack or value-type allocation, and buffer writers. Reward-only: credited where present, never penalised where a simpler style is fine.

Method: Production-source scan: density (per 1k LoC) of allocation-aware APIs — in .NET Span/Memory, ArrayPool/ObjectPool, stackalloc, ValueTask, value-type structs, IBufferWriter, string.Create, SkipLocalsInit; off .NET, with comments and strings blanked, Go's sync.Pool, preallocated slices/maps, Grow, strconv.Append* and buf[:0] reuse; the JVM's NIO buffer views, MemorySegment, primitive collections, pools and literal presizes (plus Kotlin primitive arrays and value classes, Scala AnyVal and @specialized); Swift's reserveCapacity, ContiguousArray, withUnsafe* access and ~Copyable. Activated off .NET on the same floor (400 lines, and benchmarks or 8 uses); Rust and garbage-collected scripting languages are not applicable. Reward-only. Deterministic, syntax/text detection.

No Span/Memory, pooling (ArrayPool/ObjectPool), stackalloc, ValueTask or buffer-writer usage was found. If this code sits on a hot path, these reduce the GC pressure it creates — a bonus, not a requirement.

What to do

On hot paths, prefer Span<T>/ReadOnlySpan<T>, ArrayPool<T>, stackalloc and ValueTask to cut the allocations those paths would otherwise make.

Do you agree with this assessment?

PF3 · Async & latency hygiene6.0 / 10Strong✓ Tool-verified

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, Swift, Dart) or inside a Java method returning a Reactor Mono/Flux or a Scala method returning a Future or effect — and, for a .NET library with ≥5 awaits, the share of awaits using ConfigureAwait(false). Deterministic, syntax/text detection.

Only 0/62 awaits in library code use ConfigureAwait(false). A library that captures the caller's context can stall or deadlock its host — the classic way a dependency drags an app down.

S1 · Web-Security Posture8.0 / 10Strong✓ Tool-verified

Other · Security — Transport security, security headers, secure cookies, input validation, middleware order and crypto hygiene (presence, not runtime).

Method: Roslyn plus filesystem scan: HSTS/security headers, secure cookies, input validation, middleware order, weak crypto (MD5/SHA1/DES); HTTPS-metadata context-aware. On a repository with no .NET source it reads JavaScript/TypeScript, Dart, Ruby, Scala, Rust or Elixir source itself (test, vendored, generated and minified paths not) for the arms that hold whether or not the code serves HTTP: a weak hash or cipher, key material fixed in the source, a TLS client that accepts any certificate, and (JavaScript/TypeScript, Ruby, Scala, Rust and Elixir) an obsolete TLS version; the server controls are not assessed there, and a Dart, Ruby, Scala, Rust or Elixir repository that serves no HTTP of its own is N/A on them. Deterministic.

None of the 11 security response headers the OWASP Secure Headers Project recommends (Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, …) is configured — defense in depth, even when a reverse proxy could set them. (−2.0 on this card.)
This web host's pipeline is composed here and adds no security response header (Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, a frame policy) to what it serves. — src/CleanArchitecture.Api/Program.cs:5

What to do

Add security response headers (Content-Security-Policy first, then Strict-Transport-Security, X-Content-Type-Options and a frame policy) — defense in depth, even when a reverse proxy could set them.

X1 · Async correctness6.8 / 10Strong✓ Tool-verified

Other · Code Health — Whether the code avoids sync-over-async (deadlock-prone blocking on tasks) and async void.

Method: Roslyn syntax scan: async methods scanned for .Wait()/.GetAwaiter().GetResult() and async-void outside event handlers. Deterministic, hard fact per invocation.

`async void` can't be awaited and its exceptions crash the process instead of propagating. Return `Task` — or, where the delegate contract requires void (timer/event/callback registrations), make this a thin void shim that awaits a Task-returning inner method inside try/catch so exceptions are contained. — src/CleanArchitecture.Infrastructure/Reminders/BackgroundServices/ReminderEmailBackgroundService.cs:40

X13 · Undrained process stream10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a child process that has BOTH standard streams redirected drains both — reading one to the end while the other is never read deadlocks once the child fills the unread pipe.

Method: Roslyn syntax + semantics: ProcessStartInfo launches with both streams redirected, checked for a drain of each stream across the enclosing type. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `spawn` imported from `child_process` whose stdout and stderr are both pipes (no options, no `stdio`, or `stdio` of `'pipe'`), bound to a local that never leaves its scope, where exactly one of the two streams is read, the other never, and the child’s `close`/`exit` (or the read stream’s end) is awaited; a shell redirect in the call’s arguments or a `kill` of the child suppresses it. The same rule reads Python’s `subprocess.Popen`, Dart’s `Process.start`, Ruby’s `Open3.popen3`, and Scala’s JDK process starts (`new ProcessBuilder(…).start()` with no `redirectErrorStream`/`redirectError`/`redirectOutput`/`inheritIO`, `Runtime.getRuntime.exec`) where one of `getInputStream`/`getErrorStream` is read and the other never while `waitFor()` is called or the read stream is read to its end.

X16 · Unfloored truncation loop10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a loop that shortens a string until it fits a length budget has a floor — one with none grinds the value down to the empty string, or past it into a negative-length `Substring`.

Method: Roslyn syntax + semantics: while/do loops whose body's only effect on a string is to drop its last character, checked for whether anything — a direct comparison on the length, a body guard, a break — bounds that length below. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `while`/`do` loop whose body’s one assignment to a value is `x = x.slice(0, -1)` or `x = x.slice|substring|substr(0, x.length - 1)`, driven by a condition that reads `x.length` only as a term of a larger expression — never compared directly, never tested for truthiness, and with no other read of `x` — and whose body has no `break`, `return`, `throw` or `if` naming `x`.

X17 · Uncapped recursion over a caller-supplied document10.0 / 10Exemplary○ Nothing flagged

Other · Security — Whether a walk that recurses through a JSON/XML tree handed in by its caller bounds how deep it will go — an uncapped walk lets the document's nesting choose the stack depth, and the resulting StackOverflowException cannot be caught.

Method: Roslyn syntax + semantics: methods that take a JSON/XML document node and call themselves with a child of it, reachable from an externally-callable member of the same type that accepts a document, checked for any depth parameter, descent counter or threaded arithmetic anywhere in the walk. On a repository with no .NET source it reads TypeScript off the engine’s own token stream (test, vendored, generated and minified paths and `.d.ts` not) with the same rule: a function or method with a parameter typed as a document value — `unknown`, `any`, `object`, `Record<string, unknown|any>`, a JSON alias (`JsonValue`, `JSONObject`, …) or a DOM node global the file does not rebind — that calls itself (bare, or through `this` for a method, or hands itself to a call over the value as in `value.map(walk)`) with something it took out of that value and never through an ancestor accessor such as `closest()` or `parentElement`, that is exported or reached from an exported function (a public method of the same exported class) taking such a value, and that names no depth, level, nesting, recursion, remaining or budget anywhere and threads no `+`/`-` arithmetic through a self-call. Plain JavaScript is not read: with no annotation nothing tells a parsed document from a tree the code built itself. Deterministic, provable per finding. Advisory.

X18 · Disposal-pattern correctness4.3 / 10Adequate✓ Tool-verified

Other · Code Health — Whether a type's disposal matches what it OWNS — releasing what it created, leaving alone what it was handed, and not declaring a finalizer for state that has nothing unmanaged to finalize.

Method: Roslyn syntax + semantics: every assignment to a disposable field is read to decide whether the type CREATED the value or was handed it, and the type's disposal is checked against that answer — an injected interface it disposes, a value it constructed and never releases, a finalizer on a type holding nothing unmanaged, and a disposable local whose every reference is a plain member read. A value handed to a container that disposes its contents (a parent control's `Controls` collection, a component `IContainer`) is released by that container and is not reported; generated code is out of population. On a repository with no .NET source the same ownership questions are read in JavaScript/TypeScript off the engine’s own token stream (test, vendored, generated and minified paths not): a class declaring `dispose()`, `[Symbol.dispose]()` or `[Symbol.asyncDispose]()` that disposes a field it was handed through a constructor parameter typed as a repository interface or resolved by a dependency-injection container; that assigns a field only ever from `new X(…)` of a disposable class and neither releases it anywhere in the class nor names it in its disposal member or a method that member calls, nor hands it to anything else; and a `const`/`let` local built from literals only whose every reference opens a statement operating on a non-release member of it. A class is disposable when every repository declaration of its name declares or inherits a disposal member, or when it is a documented library disposable (`vscode` EventEmitter, CancellationTokenSource and Disposable; three.js geometries, materials, textures, render targets, renderers, controls and composers). The finalizer arm has no JavaScript counterpart: a class cannot declare one. Dart is read for the owned-and-never-released arm: a Flutter `State` (or a class declaring `dispose()`/`close()`) whose library-private field is written only with direct creations of a framework controller, `FocusNode`, `StreamController` or periodic `Timer` (or a `.listen(…)` into a field declared `StreamSubscription`), which nothing in the class or its library releases (`dispose`/`close`/`cancel`) and which is never handed on except as a named argument. Ruby is read for the owned-and-never-released arm and the abandoned-local arm: a class declaring an instance `close`, `dispose`, `shutdown`, `stop`, `disconnect` or `terminate` whose instance variable is written only with a blockless core descriptor creation (`File.open`/`new`, `Tempfile`, `Dir.open`, `IO.popen`, the `socket` and `openssl` socket classes) that no method of the class closes and that is never handed on (passed, returned, stored, exposed by `attr_reader`, delegated) — a class whose superclass or mixin lies outside the repository is not judged — and a blockless creation read through and dropped (`File.open(path).read`) or held in a local that is never closed, returned, passed or stored (a `&:read` block-pass, an `autoclose: false` borrow and a `fileno` hand-over are not abandonment). PHP is read for the same two arms: a class (not a trait, and not one using a trait) declaring an instance `close`, `dispose`, `shutdown`, `stop`, `disconnect` or `terminate` whose `private` property (or a `final` class's `protected` one) is written only with a direct core `fopen`, `tmpfile`, `popen`, `proc_open`, `fsockopen`, `stream_socket_client`/`server` or `opendir` that nothing in the class closes (`fclose`, `pclose`, `closedir`, `unset`, a reset to `null`) and that is never handed on, and a handle held in a function's local, or read through as the argument of a reader, that is never closed, returned, passed, captured or stored; a `php://` stream, `curl_init`, `SplFileObject`, `PDO` and a function the repository declares under the core name are not read. Deterministic, provable per finding. Advisory.

`serviceScopeFactory.CreateScope()` (line 17) creates an `IServiceScope`, and it is dropped: `CreateScope().ServiceProvider` never names the scope, so nothing can release it. A scope owns every scoped service resolved from it — the `DbContext`, its connection, anything registered `AddScoped` — and releases them only when the scope itself is disposed; nothing here ever does, so each scope's services stay alive until the process ends. Create it with `using var scope = …CreateScope();` (or `await using` for `CreateAsyncScope`), or, when it must outlive the method, dispose it from the owning type's `Dispose`. — src/CleanArchitecture.Infrastructure/Reminders/BackgroundServices/ReminderEmailBackgroundService.cs:17

What to do

Each finding names the value and the span that decides who owns it — the `new` that created it, or the constructor parameter that handed it over. Confirm ownership from that span, then make the disposal match it: release what this type created, leave what it was injected with to whoever created THAT, and drop a finalizer whose type holds nothing unmanaged to release.

X19 · Unrestored process-global state10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a method that temporarily changes state belonging to the whole process — the working directory, an environment variable — puts it back on EVERY path: a restore reached only when nothing throws leaks the change to the rest of the process.

Method: Roslyn syntax + semantics: method bodies that write the process working directory or an environment variable and write it back in the same body, checked for whether that restore sits in a `finally`/`catch` or only on the straight-line path. On a repository with no .NET source the same rule reads production JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not): `process.chdir`, `process.env.NAME =`/`["NAME"] =` and `delete process.env.NAME`, and Deno’s `Deno.chdir`/`Deno.env.set`/`Deno.env.delete`, paired per function body (a nested function or arrow is its own body, and module top-level code is none), where the last write puts back a local the body captured from the same global or deletes a variable the first write set, with at least one statement between them; a write in a `catch`/`finally` of that body silences it. Deterministic, provable per finding. Advisory.

X2 · Cancellation propagation8.2 / 10Strong✓ Tool-verified

Other · Code Health — Whether async methods accept a CancellationToken so work can be cancelled (adoption curve).

Method: Roslyn scan: every async method (excluding framework-fixed overrides/Blazor handlers) checked for CancellationToken parameter presence. Deterministic, adoption percentage. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same question: every named async function that itself makes a request an AbortSignal can cancel (global `fetch`, axios and its file-local instances, ky, ofetch) counts, and it is compliant when its parameters or body name a signal or it hands one of its own parameters to the request as options; signatures a framework fixes (JSX event handlers, route and lifecycle exports, request-first handlers, `override`, `'use server'` modules, TanStack `mutationFn`) are exempt unless they take a signal. Deterministic, adoption percentage.

Only 26/37 async methods accept a CancellationToken, so in-flight work can't be stopped early when the caller gives up — whatever ends it in your host (shutdown signal, timeout, abandoned request, user cancel). Thread a token through the call chain and honour it at each await and loop; where a method genuinely cannot be interrupted, omitting it is a deliberate choice — judge against your hosting model.
No CancellationToken parameter — this work can't be stopped early once started. (×10) — src/CleanArchitecture.Api/Controllers/RemindersController.cs:19, src/CleanArchitecture.Api/Controllers/RemindersController.cs:34, src/CleanArchitecture.Api/Controllers/RemindersController.cs:46, …
1 async method(s) await work their caller's cancellation cannot reach: a CancellationToken they hold (a parameter, or the one a framework-fixed signature carries) is never passed on, or the call is handed CancellationToken.None, default or an already-cancelled token. Forward the caller's token to that call.
Its signature is fixed by the framework, and the token it carries (`context.RequestAborted`) reaches none of the calls here that take one — so an aborted request or a stopping host still waits for that work. Pass `context.RequestAborted` to them. — src/CleanArchitecture.Infrastructure/Common/Middleware/EventualConsistencyMiddleware.cs:13

What to do

Thread a CancellationToken through async methods so work stops promptly on cancellation.

X20 · Mistyped argument guard10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether an argument guard throws the exception its own condition describes — a guard that rejects a value for being EMPTY and reports it as `ArgumentNullException` tells the caller a parameter was null when it provably was not.

Method: Roslyn syntax: `throw new ArgumentNullException(nameof(p))` statements controlled by an `if`, whose condition is read for a test that is true of a NON-null `p` — an emptiness test that dereferences it (`p.Count == 0`, `!p.Any()`) or a BCL predicate documented true of the empty value (`string.IsNullOrEmpty(p)`). Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a `when` guard is free of side effects — a guard that increments a counter or assigns while deciding whether its arm matches applies that change during PATTERN MATCHING, on an arm that may not be selected, and skips it entirely when a short-circuit to its left answers first.

Method: Roslyn syntax: `when` guards on case labels and switch-expression arms, read for a mutation (`++`/`--`/assignment) sitting in a position the guard's own `&&`/`||`/`??`/`?:`/`?.` can skip. Deterministic, provable per finding. Advisory.

X22 · Contradicted release guard10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a method that TAKES a lock or semaphore and gives it back from a flag-guarded `finally` returns the value that flag implies — reporting success while the guard hands the primitive back admits a second caller the exclusion was there to keep out, and reporting failure while the guard keeps it leaves nothing to ever give it back.

Method: Roslyn syntax: `try` statements whose `finally` releases a synchronisation primitive under a bare local-bool guard, where the method also TOOK that same primitive before the `try`, checked for a `return` of a bool literal whose value disagrees with the flag state the method's own straight-line assignments put it in. Deterministic, provable per finding. Advisory.

X23 · Unguarded diagnostic materialisation10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether the work a diagnostic log line costs is paid only when that line is wanted — C# evaluates a call's arguments BEFORE the call, so a trace/debug message joined or projected out of a collection is built in full on every pass, and then discarded by a sink the shipped configuration leaves switched off.

Method: Roslyn syntax: log calls at a diagnostic level (a `Log`-prefixed method naming Trace/Debug/Verbose, or a bare `Debug`/`Trace`/`Verbose` on a receiver named for a logger), whose argument list is read for a call whose cost scales with a sequence — a LINQ operator, a materialisation, `string.Join`, a serializer — with no enclosing level check or conditional-compilation region. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `debug`/`trace`/`verbose` call on a receiver named for a logger, or a `log`-prefixed method naming the level, whose argument calls an array operator (`map`/`filter`/`reduce`/`sort`/…), `Array.from`, `Object.keys/values/entries`, `JSON.stringify`/`util.inspect` over anything but a literal, or an array `join` — outside any arrow or function passed as an argument, which the logger calls only when the level is on — with no enclosing `if`, `&&` or `?:` whose condition names a level, a level string, or the `NODE_ENV`/`__DEV__`/`DEV` build switch. Deterministic, provable per finding. Advisory.

X24 · Document value interpolated into markup unescaped10.0 / 10Exemplary○ Nothing flagged

Other · Security — Whether text read out of the document being converted is escaped before it is written into generated markup — a value the document's author chose, interpolated into an attribute the surrounding literal delimits, can close that attribute and open another.

Method: Roslyn semantic model over the whole compilation: a string-typed `Value`/`InnerText`/`InnerXml`/`Text` member declared inside `DocumentFormat.OpenXml` or `System.Xml` is a taint SOURCE, propagated through assignments, returns, arguments, tuple elements and string composition to its transitive closure, then read at interpolated-string holes that sit in a markup position the surrounding literal itself delimits. Escaper/encoder calls and enclosing validator conditions cut the flow. Flow- and container-insensitive by construction. A second arm needs no provenance at all and reports a type that CONTRADICTS ITSELF — the same expression escaped at one delimited markup hole and interpolated raw at another hole in the same markup position of the same type, which the type's own escaping proves is a defect without knowing where the value came from. On a repository with no .NET source it reads JavaScript/TypeScript off the token stream with the same rule: a DOM read of raw document text (`getAttribute`, `textContent`, `innerText`, `nodeValue`) is the source, propagated through local bindings and string composition, and judged at template-literal and concatenation holes in the same two delimited markup positions; escapers and validating conditions cut it, and documentation-site, test, vendored and minified scripts are not read. Deterministic, provable per finding. Advisory.

X25 · Inert configuration knob10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a value the caller is invited to supply is the value the type actually uses — a constructor parameter stored in a private field that nothing ever reads while the default it was given is spelled out a second time at the site that should have read it, a keyed lookup that falls back to a different setting than the one its key names while the same type falls back to the matching one for that same key, or a culture-sensitive parse given no format provider by a type that feeds its own settable culture to the same kind of parse elsewhere, or a number an entry point writes to standard output under the host's culture while the same entry point formats with the invariant culture elsewhere. Either way, every caller who supplies a value silently gets something else.

Method: Roslyn syntax: private instance fields of a non-partial type assigned in a constructor from one of its own parameters with a `??` fallback, checked for whether anything in the type body reads the field and whether that same fallback expression is spelled out again outside the constructor; and `??` fallbacks onto a member access from a lookup call carrying exactly one string literal, grouped by that key across the type and checked for a fallback member whose folded name disagrees with the key while a sibling site for the same key agrees with it. On a repository with no .NET source the first two arms read JavaScript/TypeScript off the engine’s own token stream (tests included, bundles and vendored paths not): a `#x`, `private` or `private` parameter-property instance field filled in the constructor from a parameter (or one member of one) through `??`/`||` or a parameter default, never read anywhere in the file by name, whose constructed default is spelled again in the class body; and `lookup("key") ?? s.member` grouped by key per class, or per module outside every class. The culture arm has no JavaScript counterpart: its parses take no locale. Deterministic, provable per finding. Advisory.

X26 · Unsynchronised callback handoff10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a value handed from a callback to the body that waits on it crosses on something built to be crossed — a `Queue<T>`/`List<T>`/`Dictionary<K,V>` written inside an event handler and read back outside it is mutated by two flows at once, and the semaphore or completion source beside it orders how MANY items exist while leaving the collection's own head, tail and backing array unprotected.

Method: Roslyn syntax: method, accessor, local-function and lambda bodies that declare BOTH a non-thread-safe generic collection (`Queue`/`Stack`/`List`/`Dictionary`/`HashSet`/`Sorted*`/`LinkedList`) and a synchronisation primitive (`SemaphoreSlim`/`TaskCompletionSource`/`ManualResetEvent(Slim)`/`AutoResetEvent`/`CountdownEvent`) as locals, then read for a `+=`-registered lambda that raises that primitive while the body outside every lambda waits on it — and, in that scope, a mutating call on the collection inside the lambda paired with a mention of it outside. Any `lock` in the scope abstains it. On a repository with no .NET source the same handoff is read in Java off the engine’s own token stream (test source sets, vendored and demonstration paths not): an `ArrayList`/`LinkedList`/`ArrayDeque`/`PriorityQueue`/`Hash*`/`LinkedHash*`/`Tree*` local and a `CountDownLatch`/`Semaphore`/`CompletableFuture` local, a lambda or anonymous class that raises the primitive and mutates the collection, and a wait outside it; any `synchronized` or `lock()` abstains the body. Because each of those primitives orders what the callback wrote before raising it, only a touch that provably overlaps the callback is convicted: one after the registration and before the next wait, or one in a loop registered-before, waiting on every pass and not declaring the collection. Deterministic, provable per finding. Advisory.

X27 · Collection changed while being enumerated10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a `foreach` leaves the collection it is walking alone — a body that adds to or removes from the very collection the loop is enumerating invalidates the enumerator it is holding, so the next `MoveNext` throws `InvalidOperationException` and the remaining items are never seen.

Method: Roslyn syntax + semantics: `foreach` statements whose body calls a structural mutator (`Add`/`Remove`/`Clear`/`Insert`/…) on the very expression the loop is enumerating. Two arms. ARM A — the source is a concrete fragile BCL collection, or a live `Keys`/`Values` view over one, and the mutator resolves to that same collection's own member; concurrent and immutable collections and arrays are outside the population by construction, since their enumerators survive a structural change. ARM B — the source is an argument-less accessor CALL on a receiver whose body is in source: the accessor must return a stored field VERBATIM and a sibling member must structurally change that same field, both read off the implementations rather than from the members' names. A mutation the loop provably exits immediately after (`break`/`return`/`throw`/`goto`), or one written inside a nested loop or a lambda, is counted and never reported. Deterministic, provable per finding. Advisory.

X28 · Index access outside its own emptiness guard10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a condition that tests a value for emptiness indexes that same value only where the test holds — an `||` written one parenthesis too far to the left leaves an index access outside the guard beside it, so the empty case the guard exists to anticipate reaches the index and throws.

Method: Roslyn syntax only, no semantic model: the OUTERMOST `&&`/`||` of every boolean condition, read for a symbol the condition tests for emptiness (`string.IsNullOrEmpty`/`IsNullOrWhiteSpace`, a `Length`/`Count` comparison against a literal, `Any()`, a `Length`/`Count` pattern, or a comparison against `""`) and ALSO indexes. Each `symbol[...]` access is placed by a boolean-reachability walk from the access up to the outermost connective: an access is COVERED when some enclosing step has it in the right operand and the left operand, under the truth value that step forces, proves the symbol non-empty — a recursion over `&&`/`||` whose true- and false-directions are asymmetric. A finding needs BOTH an uncovered access and a covered one on the same symbol in the same condition, which is the agreeing twin that separates a misplaced parenthesis from an unrelated length test. Bare index accesses with no emptiness test in the condition are neither counted nor reported; a non-identifier receiver and a lambda nested inside the condition are outside the population. Deterministic, provable per finding. Advisory.

X29 · Per-element action decided by a fixed element10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a decision taken once per element is taken ABOUT that element — a test inside a counted loop that reads a fixed subscript of the very collection its guarded statement indexes by the loop variable applies element zero's answer to all of them, so the elements that differ from it are all handled wrongly, and in the same direction.

Method: Roslyn syntax only, no semantic model: every `for` statement declaring exactly ONE loop variable, and every `if` inside its body that is not under a nested loop or a lambda. A site enters the population when the `if`’s condition never mentions the loop variable while the statement it guards indexes some collection by that variable ALONE (`c[i]`; `c[i + 1]` and `c[i, j]` are outside it). A finding additionally needs the AGREEING TWIN at the same-collection grain: the condition must read THAT SAME collection at a subscript that does not move — written into the condition, or reached through a local declared BEFORE the loop, so an alias bound inside the body is not followed. Both collection expressions must be simple identifiers. On a repository with no .NET source the same rule reads JavaScript/TypeScript off the engine’s own token stream (tests included, bundles and vendored paths not): a `for (let|var|const x = …; …; …)` with one declarator and a braced body, an alias followed only when it is declared before the loop in a block that encloses it and never assigned inside the loop. Deterministic, provable per finding. Advisory.

X30 · Support guard that admits what it rejects10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a guard written as a NEGATED `||` says what its author meant — `!(a || b || x != k)` is `!a && !b && x == k` by De Morgan, so a bail-out that mixes capabilities the code needs with a fault it refuses turns inside out: it fires only where the capabilities are ABSENT, and lets every value the fault term names walk straight into the body that cannot handle it.

Method: Roslyn syntax only, no semantic model: every logical-not whose operand is a parenthesised `||` chain of two or more disjuncts, flattened (a left-nested `a || b || c` read once would see `(a || b)` as one disjunct). A site enters the population on that shape alone. A finding additionally needs the disjuncts to DISAGREE in polarity: at least one bare boolean read — an identifier or member access, never an invocation, which is a predicate rather than a capability flag — and at least one `x != <constant>`, the only form that negates into an exact-value pin (`== null` negates into a looser requirement and is outside the fault set). Consistently-polarised disjunctions, all-fault or all-capability, are counted and never reported; a negated `&&` is outside the population entirely. No same-receiver gate: it was measured to cost a real defect and remove no false positive. Deterministic, provable per finding. Advisory.

X32 · Type resolved by simple name across every loaded assembly10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether a plugin lookup names the type it means — searching every assembly loaded into the process for a candidate whose SIMPLE name equals a string supplied at runtime, and taking the first one found, is decided by assembly LOAD ORDER rather than by this source, so the same name can resolve to a different type on the next run.

Method: Roslyn syntax only, no semantic model: every invocation of `First`/`FirstOrDefault`/`Single`/`SingleOrDefault` whose OWN expression subtree contains both a `GetAssemblies()` call and a `GetTypes()`/`GetExportedTypes()` call — a single-element pick out of every type loaded into the process. A nested selector in the same chain sees no `GetAssemblies()` in its own subtree and is outside the population, so one lookup counts once however many links its chain has. A finding additionally needs both remaining halves: the selector must be `First`/`FirstOrDefault` (`Single`/`SingleOrDefault` reports the ambiguity rather than resolving it, and is counted and never reported), and the chain must carry an `==` comparison of `<lambda parameter>.Name` against something that is not a literal. The receiver must be a plain identifier bound by one of the chain’s own lambdas, which places `assembly.GetName().Name == "X"` outside the rule by construction. One exemption: a `.Name` test joined by `&&` to a `FullName`/`AssemblyQualifiedName` test on the same identifier is spared; joined by `||` it is not. Deterministic, provable per finding. Advisory.

X4 · Structured logging10.0 / 10Exemplary○ Nothing flagged

Other · Code Health — Whether log calls use message templates (queryable) rather than interpolated strings.

Method: Roslyn syntax scan: every log call-site counted; interpolated-string first-argument violations flagged. Population is all log calls, not estimated. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `trace`/`debug`/`info`/`warn`/`error`/`fatal`/`verbose`/`silly`/`http`/`log` call on a receiver named for a logger, in a package whose own or an enclosing `package.json` declares a logger that carries values as fields (pino, pino-http, nestjs-pino, Fastify, winston, bunyan, tslog, LogTape, roarr), whose first deciding argument is a template literal with substitutions; an object-literal fields argument is stepped over, a plain string message clears the call. Python is read the same way: a `debug`/`info`/`warning`/`error`/`exception`/`critical`/`log` call on a logger in a file that imports the standard library’s `logging` or structlog (loguru, which formats at the call, is not judged), whose message is a whole f-string with a non-constant field; a `%`-formatted, `.format()`-ed or concatenated message is not convicted, as in C#. PHP is read the same way: a PSR-3 level call (`emergency`…`debug`, `log`) on a logger (`$logger`, `$this->logger`, Laravel’s `Log::`, `logger()`, `\Drupal::logger()`) in a package whose `composer.json` requires a PSR-3 logger or a framework that hands one out (psr/log, Monolog, Laravel, Symfony, Drupal, CakePHP), or a file that imports one, whose message is a double-quoted string interpolating a variable; a single-quoted message clears the call, and `sprintf` or `.` concatenation is not convicted, as in C#. Dart is read the same way: a `trace`/`debug`/`info`/`warn`/`error`/`fatal` call on Sentry’s structured logger (`Sentry.logger`) whose message is a whole string literal interpolating a value (`$name`, `${…}`); the `Sentry.logger.fmt` template API clears the call. Dart that logs only through loggers with one message and no fields (package:logging, package:logger, talker, dart:developer) is not applicable rather than a reach gap. Ruby is read the same way: a `trace`/`debug`/`info`/`warn`/`error`/`fatal` call on the console gem’s `Console` (declared by a Gemfile, gemspec or Gemfile.lock, or required) or, where SemanticLogger, Ougai or dry-logger is declared or required, on a receiver named for a logger (`logger`, `@logger`, `Rails.logger`, `log`), whose first deciding argument is, as the whole argument, a double-quoted string interpolating a non-constant value (`#{…}`, `#@ivar`); a plain literal clears the call, keyword arguments are the fields, and a block, `%`-format or `+` concatenation is not convicted. Ruby that logs only through the standard Logger (Rails.logger) is not applicable rather than a reach gap. Deterministic.

X5 · Nullable reference types8.1 / 10Strong✓ Tool-verified

Other · Code Health — Whether nullable reference types are enabled and not undermined by heavy `!` suppression.

Method: Roslyn compiler-options scan: NullableContextOptions per project; null-forgiving (!) suppression density per 1k syntax nodes. Deterministic, adoption plus suppression penalty.

~2.4 `!` suppressions per 1k syntax nodes — 26 suppression(s) across the 10879 syntax node(s) in code where nullable warnings are ENABLED, which is the only code a `!` can suppress anything in (a `!` under `#nullable disable` is inert and is not counted, and its file's nodes are not in the denominator). Each one tells the compiler to trust you about null, suppressing the very safety NRTs provide.

What to do

Enable <Nullable>enable</Nullable> across all projects and resolve warnings rather than suppressing with `!`.

Unscored — 4 check(s) recorded observations but carry no score

These checks ran and found something, but they do not carry a score — either by design (an advisory check reports evidence rather than grading it) or because they could not be scored here. They are excluded from the score for that reason, not because there was nothing to see.

AXH1 Runtime security headers — 11 observation(s) recorded · Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
AXI1 Runtime container hardening — 1 observation(s) recorded · Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
AXR1 Runtime accessibility (rendered) — 2 observation(s) recorded · Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
P12 CI test-gate honesty — 1 observation(s) recorded · Reported, not scored — this card publishes what the CI gate does with the test inventory rather than grading it. The findings above are its output.

Not evidenced — 3 control(s) we could not find positive evidence for

These checks grade a working control, and the repository shows no evidence of one. That is deliberately not scored as a zero: a repository cannot show an ops runbook, a database TTL or an infrastructure-side audit log, so absence of evidence here is not evidence the control is missing. It is also not a statement that the check is irrelevant to this codebase — the thing it grades applies; we just could not see it. Excluded from the score either way.

C5 Data-Subject Rights — Repo shows no corroborated data-subject-rights mechanism (erasure / export-portability / consent) tied to a subject id or GDPR vocabulary — absence of evidence is not evidence of a working control. Implement erasure, data export/portability and consent tracking over the subject's records.
P5 DR & Backup — not evidenced — repo shows no backup/RTO/RPO controls; absence of evidence is not evidence of a working control
P6 Release Hygiene — not evidenced — no changelog, version stamp or semver release tag in the repo

Not included — 35 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.

AXA1 Runtime unauthenticated reachability — This run crawled public routes only — it had no logged-in session, so there is no authenticated surface to compare anonymous access against and nothing was measured. This is a statement about this run, not about your application: nothing here says access control is missing, and nothing here says it is present.

C1 Data Protection — This is a dotnet-new template — at-rest encryption and key-vaulting are deferred to the application you build from it. Add ASP.NET Data Protection / column encryption + a key vault for your real data store when you productionise.
D16 Bus Factor — single-maintainer repository — bus factor is not applicable
D20 ADR Quality — N/A — this repo declares itself a template / kata / sample / demo; a formal ADR log is deferred to a real application built from it.
D23 Boundary Type-Coupling — small single-context codebase (1,781 production LoC in the .NET projects) — bounded contexts are not needed at this size No bounded-context organisation was detected either — neither a context-shaped layout, nor 2+ sibling source directories each declaring an aggregate root, nor 2+ projects each declaring an entity of their own. Aggregate roots were found in only one source directory (CleanArchitecture.Domain), which is a layered codebase, not two contexts. Declaring this codebase's bounded contexts (≥2) would let cross-boundary type coupling be assessed. Declare them in `.codehealth/config.yaml` at the repository root (create it if absent), mapping each context name to the module-path or namespace prefixes that belong to it — e.g. `architecture:` → `contexts:` → `Billing: ["src/billing", "Acme.Billing"]`, `Catalog: ["src/catalog", "Acme.Catalog"]`.
D25 ADR Conformance — no ADRs to check
D32 Data Compliance (PII/GDPR) — 30 file(s) were not parsed by semgrep — the PII/GDPR ruleset never ran over them
D36 Supply-chain Provenance & Signing — This is a dotnet-new template — it produces no released artifact to attest. Supply-chain provenance, signing and SBOM are deferred to the application you build from it (add SLSA provenance / cosign signing / an SBOM in your app's release pipeline).
D37 Vulnerability-disclosure Policy — No vulnerability-disclosure policy file found (SECURITY.md/.markdown/.rst/.txt at root or under .github/.forgejo/.gitea/docs, .well-known/security.txt). A coordinated-disclosure policy may live off-repo, so this is not evidenced rather than failed.
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.
D43 Malicious Dependencies — Not scored — no dependency manifest in a supported ecosystem was read for this repository. A gap in the analyzer's language coverage, NOT a finding that the repository is free of vulnerable dependencies (a Python pyproject.toml/requirements.txt (pip/uv/Poetry), a Swift Package.swift/Package.resolved, a Cargo manifest, a Go module (go.mod/go.sum), a Gradle version catalogue, a Maven POM, an sbt build (build.sbt), composer.json, package.json, a Dart pubspec.yaml, an Elixir mix.exs/mix.lock (Hex), a rebar.config / erlang.mk DEPS (Hex), a Ruby Gemfile/Gemfile.lock or .gemspec (Bundler/RubyGems) — not scanned yet).
D7 Architectural Integrity — no checkable ADRs and no dependency cycles — architectural integrity not assessed
DM3 Integration-event coupling — no integration events detected — coupling check not applicable
ES1 Event Sourcing — not scored — this repository shows none of the 3 signals this lens looks for
P2 Observability — This repo declares itself a template / kata / sample / demo — code meant to be read or copied, not operated. Structured logging, tracing/metrics and health checks are deferred to the application you build from it, so their absence is not a defect here. The dimension reactivates once the repo becomes a real app.
P3 Security & performance tooling — This repo declares itself a template / kata / sample / demo — code meant to be read or copied, not operated. SAST, secret/dependency scanning and performance benchmarks are deferred to the application you build from it, so their absence is not a defect here. The dimension reactivates once the repo becomes a real app.
P7 Outbound HTTP resilience — no outbound HTTP usage detected — no HttpClient/IHttpClientFactory/AddHttpClient in source, and no Refit/RestSharp/Flurl.Http namespace or package reference
SC1 Supply-chain hygiene — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
X10 Duplicated predicate — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
X6 Hand-rolled structured-format parsing — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.

AX3 · Project dependency cycles · Namespace dependency cycle · ×1

Namespace dependency cycle src/CleanArchitecture.Domain/Users/Subscription.cs:2 — The namespaces CleanArchitecture.Domain.Subscriptions ↔ CleanArchitecture.Domain.Users depend on each other. The lightest dependency in the cycle is CleanArchitecture.Domain.Subscriptions → CleanArchitecture.Domain.Users (CleanArchitecture.Domain.Subscriptions.Subscription → CleanArchitecture.Domain.Users.SubscriptionType, 1 type pair(s)); cut that one first, e.g. by moving the shared type to a namespace both can use or inverting it behind an interface.

D17 · Explicit Debt · EmptyCatchBlock · ×1

EmptyCatchBlock src/CleanArchitecture.Infrastructure/Common/Middleware/EventualConsistencyMiddleware.cs:30 — empty catch block — the error is discarded with nothing recorded, so a failure here leaves no trace anywhere. Record it through whatever this codebase already uses to report problems, or let it propagate. Where swallowing one specific failure really is correct — as it often is on a teardown/dispose path where throwing would mask the original failure — catch exactly that exception type and write down WHY in a comment on the catch. Both are needed: a comment on a catch-all still swallows every failure nobody anticipated, and a note that only restates the swallow ("ignored", "do nothing") is read as no explanation at all.

D17 · Explicit Debt · WriteOnlyPrivateField · ×1

WriteOnlyPrivateField tests/CleanArchitecture.Application.SubcutaneousTests/Subscriptions/Commands/CreateSubscription/CreateSubscription.ValidationTests.cs:6 — private TestCurrentUserProvider _currentUserProvider — assigned 1 time(s), read never — this field is written and never read anywhere its type can be reached from, so the state it keeps answers no question: every assignment to it computes a value that nothing observes, on every instance, for the lifetime of each one. It reads as a flag the code branches on, and nothing branches on it. Delete the field and its assignments — or, if the value was MEANT to be consulted, the missing read is the defect this row is pointing at, and the branch that should have depended on it is not there.

PF3 · Async & latency hygiene · Awaits without ConfigureAwait(false) · ×40

Awaits without ConfigureAwait(false) — Only 0/62 awaits in library code use ConfigureAwait(false). A library that captures the caller's context can stall or deadlock its host — the classic way a dependency drags an app down.

Dead code: RemoveRangeAsync src/CleanArchitecture.Application/Common/Interfaces/IRemindersRepository.cs:11 — Method RemoveRangeAsync — Roslyn's SymbolFinder walked every project the solution loads, including CleanArchitecture.Application, and found no reference to it. That walk cannot see three kinds of caller, so check them before removing it: code outside the solution file (a solution is a curated list, not the repository — a sibling test tree with its own .sln is invisible), a call resolved by reflection or dependency injection from the symbol's name, and any project the workspace could not load.

DM11 · Constructible invalid state · Constructible in an invalid state · ×2

Constructible in an invalid state: Reminder src/CleanArchitecture.Domain/Reminders/Reminder.cs:21 — `Reminder`'s public constructor takes `text` as raw primitives, and neither of the two things that would make that safe was found. What was searched, so you can tell an absence from a miss: for VALIDATION, the constructor body was scanned for `throw`, `Guard.`, `Ensure.`, `ArgumentNullException`, `ArgumentException`, `CheckRule` or `Requires.` — a guard reached through a helper method those tokens do not name is not seen; for a FACTORY, only this type's OWN static members were read, and only names beginning `Create`, `Of`, `From`, `New` or `Build` — one inherited from a base type, one on a companion builder, or one called `Parse`, `Make` or `Rehydrate` is not seen. If either exists, this row is wrong. If neither does, a caller can build a `Reminder` that breaks the rules it exists to enforce, and every rule downstream then has to cope with a state the model said was impossible. Guard in the constructor, take value objects that validate themselves, or make the constructor private behind a `Create` that can refuse.
Constructible in an invalid state: User src/CleanArchitecture.Domain/Users/User.cs:28 — `User`'s public constructor takes `firstName`, `lastName`, `email` as raw primitives, and neither of the two things that would make that safe was found. What was searched, so you can tell an absence from a miss: for VALIDATION, the constructor body was scanned for `throw`, `Guard.`, `Ensure.`, `ArgumentNullException`, `ArgumentException`, `CheckRule` or `Requires.` — a guard reached through a helper method those tokens do not name is not seen; for a FACTORY, only this type's OWN static members were read, and only names beginning `Create`, `Of`, `From`, `New` or `Build` — one inherited from a base type, one on a companion builder, or one called `Parse`, `Make` or `Rehydrate` is not seen.

ED5 · Idempotency · Non-idempotent mutation · ×2

Non-idempotent mutation: Events.ReminderDeletedEventHandler.Handle src/CleanArchitecture.Application/Reminders/Events/ReminderDeletedEventHandler.cs:10 — `Events.ReminderDeletedEventHandler.Handle` mutates persistent state (a repository write) with no idempotency guard, and the model confirms a re-run would double-apply it. A retry or at-least-once redelivery means it can run twice — add an exists/dedup check, an upsert, an idempotency-key/inbox, or a versioned write.
Non-idempotent mutation: Events.SubscriptionCanceledEventHandler.Handle src/CleanArchitecture.Application/Subscriptions/Events/SubscriptionCanceledEventHandler.cs:11 — `Events.SubscriptionCanceledEventHandler.Handle` mutates persistent state (a repository write) with no idempotency guard, and the model confirms a re-run would double-apply it. A retry or at-least-once redelivery means it can run twice — add an exists/dedup check, an upsert, an idempotency-key/inbox, or a versioned write.

Container process runs as root: clean-architecture-api — 'clean-architecture-api' (.-api) runs as uid 0 — no user was specified, or one resolving to root was.

D12 · Dependency Hygiene · Prerelease dependency · ×1

Prerelease dependency: StyleCop.Analyzers — StyleCop.Analyzers resolves to 1.2.0-beta.556, a prerelease build. Prerelease packages carry no support policy, may change breaking between previews and can be unlisted — pin a stable release before shipping, or record the reason this preview is required.

D22 · Internal API Consistency · Inconsistent Mediator interface usage · ×1

Inconsistent Mediator interface usage: RemindersController and TokensController use ISender, while SubscriptionsController uses IMediator. In MediatR, ISender is a subset of IMediator; mixing them suggests inconsistent abstraction choices or copy-paste errors. — Standardize on ISender for all controllers if only sending commands/queries is required, or IMediator if notifications are needed. Prefer ISender for better testability and explicit intent. (signatures: RemindersController.RemindersController(ISender _mediator) | SubscriptionsController.SubscriptionsController(IMediator _mediator) | TokensController.TokensController(ISender _mediator))

Duplicated block (6 lines × 2) src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs:71 — src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs:71-76 | REDACTED:57-62 — the copies sit in sibling files of one directory, so a shared home is within easy reach: extract the block into a single shared function the call sites can all reach — a file they already depend on, or a new one alongside them — and call it from both call sites, so a change lands once.

D5 · Coupling · Off the main sequence · ×1

Off the main sequence: CleanArchitecture.Domain src/CleanArchitecture.Domain/CleanArchitecture.Domain.csproj:1 — CleanArchitecture.Domain: abstractness 0.17, instability 0.00, distance 0.83 — zone of pain — concrete and depended on by 2 project(s), so it's rigid to change.

DM4 · Rich vs anemic model · Anemic entity · ×1

Anemic entity: Subscription src/CleanArchitecture.Domain/Users/Subscription.cs:6 — `Subscription` is an aggregate/entity with 1 data propert(ies) but no state-changing behaviour (only data and queries) — the business logic lives in a service.

P12 · CI test-gate honesty · Coverage collected but not gated · ×1

Coverage collected but not gated — CI collects a coverage report but no step enforces a minimum — coverage could halve and CI stays green. Add a step that fails the build when coverage drops below a floor (your coverage tool's minimum-threshold flag, or a coverage-gate action) so the number guards something. What was searched, so you can tell an absence from a miss: this repository's CI files AND its coverage configuration — the well-known coverage and test-runner config files, read at the repository root and inside workspace package directories two levels down, so a floor declared beside the tests rather than in the pipeline is credited — matched against the threshold settings this check knows by name. A floor set in your coverage service's web UI rather than in a committed file, or under a setting whose name is not one of those, is not seen here.

X1 · Async correctness · async void method · ×1

async void method: SendEmailNotifications src/CleanArchitecture.Infrastructure/Reminders/BackgroundServices/ReminderEmailBackgroundService.cs:40 — `async void` can't be awaited and its exceptions crash the process instead of propagating. Return `Task` — or, where the delegate contract requires void (timer/event/callback registrations), make this a thin void shim that awaits a Task-returning inner method inside try/catch so exceptions are contained.

X18 · Disposal-pattern correctness · DI scope created and never disposed · ×1

DI scope created and never disposed src/CleanArchitecture.Infrastructure/Reminders/BackgroundServices/ReminderEmailBackgroundService.cs:17 — `serviceScopeFactory.CreateScope()` (line 17) creates an `IServiceScope`, and it is dropped: `CreateScope().ServiceProvider` never names the scope, so nothing can release it. A scope owns every scoped service resolved from it — the `DbContext`, its connection, anything registered `AddScoped` — and releases them only when the scope itself is disposed; nothing here ever does, so each scope's services stay alive until the process ends. Create it with `using var scope = …CreateScope();` (or `await using` for `CreateAsyncScope`), or, when it must outlive the method, dispose it from the owning type's `Dispose`.

X2 · Cancellation propagation · Async method drops its ambient CancellationToken · ×1

Async method drops its ambient CancellationToken: InvokeAsync src/CleanArchitecture.Infrastructure/Common/Middleware/EventualConsistencyMiddleware.cs:13 — Its signature is fixed by the framework, and the token it carries (`context.RequestAborted`) reaches none of the calls here that take one — so an aborted request or a stopping host still waits for that work. Pass `context.RequestAborted` to them.

X3 · Exception handling · Swallowed exception (empty catch) · ×1

Swallowed exception (empty catch) src/CleanArchitecture.Infrastructure/Common/Middleware/EventualConsistencyMiddleware.cs:30 — An empty catch block silently discards the error — failures vanish with no log and no rethrow. Log it, handle it, or don't catch it.

S1 · Web-Security Posture · No security response headers detected · ×2

No security response headers detected — None of the 11 security response headers the OWASP Secure Headers Project recommends (Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, …) is configured — defense in depth, even when a reverse proxy could set them. (−2.0 on this card.)
No security response headers detected src/CleanArchitecture.Api/Program.cs:5 — This web host's pipeline is composed here and adds no security response header (Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, a frame policy) to what it serves.

C3 · Audit Trail · Partial audit-trail evidence · ×1

Partial audit-trail evidence — An audit mechanism is present, but the trail is not yet complete — missing: an immutable audit-log / audit-trail type to write to, [Audited] per-entity coverage.

C4 · Data Retention · Partial data-retention evidence · ×1

Partial data-retention evidence — A retention mechanism is present, but the data-lifecycle is not yet complete — missing: a scheduled purge / cleanup job (PurgeOlderThan / CleanupJob), a documented retention period / data-expiry.

D34 · Knowledge Freshness · Orphaned files with no living knowledge · ×1

Orphaned files with no living knowledge — 5 of 5 analysed file(s) have no living knowledge left — their last meaningful change has decayed away, so if one breaks, no one currently understands it (counted over production source files of roughly 2,400 bytes or more, excluding vendored, generated and example/demo trees and test files identified by path convention, largest first; 5 of the 107 production source files in this repository met that bar). None is large enough to earn a read-through of its own, so this row stands in for the per-file rows rather than raising one each — most significant first: src/CleanArchitecture.Domain/Users/User.cs, src/CleanArchitecture.Infrastructure/DependencyInjection.cs, src/CleanArchitecture.Api/Controllers/RemindersController.cs, src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs, src/CleanArchitecture.Infrastructure/Reminders/BackgroundServices/ReminderEmailBackgroundService.cs. Attach the read to the next change that touches one of them: have a second person review that change, and leave behind a short comment or test recording what the file is for, so the knowledge comes back at the cost of a change you were making anyway.

M2 · Architecture documentation · No ADRs · ×1

No ADRs — 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.

P10 · Library API & versioning · Large public API surface · ×1

Large public API surface — 13/14 types (93%) are public. For a library, every public type is a stability contract — make internal-by-default and expose only the intended API.

P10 · Library API & versioning · No explicit versioning · ×1

No explicit versioning — No explicit version was found by any of the six routes this check reads: a `<Version>` or `<VersionPrefix>` property; a `GitVersion` or `MinVer` reference; the split Arcade spelling (`<MajorVersion>` AND `<MinorVersion>` together); a hand-written `[assembly: AssemblyVersion]` in source, with `bin/` and `obj/` excluded so the SDK's generated AssemblyInfo cannot satisfy it; or a version handed to MSBuild by the pipeline, as `-p:Version=` / `-p:PackageVersion=` on a `dotnet build` or `dotnet pack` line. Only project files, first-party source and CI files are read, so a version computed somewhere none of those can see is invisible here. A published library needs explicit semantic versioning so consumers can reason about breaking changes.

P4 · Deployment & Rollback · No rollback/health safety · ×1

No rollback/health safety — Deployment is orchestrated by compose, but no service declares a `healthcheck:` and nothing pins a previous image to fall back to — the runtime can tell that the container is up, not that it is serving, so a bad release is harder to detect and reverse.

P4 · Deployment & Rollback · No release approval gate · ×1

No release approval gate — Deployment is automated and no gate that pauses it for a human is DECLARED IN THIS REPOSITORY'S PIPELINE FILES. What was read: every file under `.github/workflows/`, `.forgejo/workflows/`, `.gitea/workflows/`, `.azuredevops/` and `.azure-pipelines/`, plus `.gitlab-ci*` and `azure-pipelines*` — with comment text stripped, so documenting a gate is not declaring one. What would have counted: GitLab's `when: manual`, CircleCI's `type: approval`, an Azure `ManualValidation@` task or an `approvals:` block, a Jenkins `input` step, a `uses:` step naming an approval action, an `environment:` paired with `reviewers` / `required_reviewers` / `protection` / `wait-timer` / `deployment_branch_policy`, a draft-release step, a `workflow_dispatch` promotion, or a release-event gate. ★ What this cannot see, because none of it is a file: a GitHub environment whose required reviewers are configured in repo SETTINGS, a branch protection rule, or an organisation deployment policy — all of them real, enforced gates that live outside the repository. If yours is one of those, this row is wrong and nothing in the tree could have told us. Otherwise: whatever reaches the release trigger goes to production unreviewed, so a mistaken merge or tag is live before anyone can stop it.

PF1 · Benchmark discipline · No performance benchmarks · ×1

No performance benchmarks — No benchmark suite was found by the two searches this check runs. FIRST, a BenchmarkDotNet package reference in any project file — every project the workspace loaded, plus a walk of project files on disk that never loaded, because a benchmark suite is exactly the project a partial load drops. SECOND, a script harness: a file whose name contains `benchmark` and ends `.py`, `.sh`, `.ps1`, `.bash`, `.rb`, `.js` or `.mjs`, credited ONLY when this repository's CI text also mentions benchmarks — a harness no pipeline runs is read as a fixture, deliberately. Neither search can see a benchmark suite in another ecosystem's idiom (a Go `testing.B` file, a JMH or criterion project, a pytest-benchmark run), so this is 'no benchmark found by those two searches', not a verdict that the repository has none. Where code is performance-sensitive, a benchmark guards against silent regressions — but it's a bonus here, not a deduction.

PF2 · Allocation hygiene · No allocation-aware APIs detected · ×1

No allocation-aware APIs detected — No Span/Memory, pooling (ArrayPool/ObjectPool), stackalloc, ValueTask or buffer-writer usage was found. If this code sits on a hot path, these reduce the GC pressure it creates — a bonus, not a requirement.

X2 · Cancellation propagation · Not all async methods take a CancellationToken · ×1

Not all async methods take a CancellationToken — Only 26/37 async methods accept a CancellationToken, so in-flight work can't be stopped early when the caller gives up — whatever ends it in your host (shutdown signal, timeout, abandoned request, user cancel). Thread a token through the call chain and honour it at each await and loop; where a method genuinely cannot be interrupted, omitting it is a deliberate choice — judge against your hosting model.

X2 · Cancellation propagation · Some async methods drop the CancellationToken they accept · ×1

Some async methods drop the CancellationToken they accept — 1 async method(s) await work their caller's cancellation cannot reach: a CancellationToken they hold (a parameter, or the one a framework-fixed signature carries) is never passed on, or the call is handed CancellationToken.None, default or an already-cancelled token. Forward the caller's token to that call.

X5 · Nullable reference types · Null-forgiving operator (`!`) suppressions reduce the NRT score · ×1

Null-forgiving operator (`!`) suppressions reduce the NRT score — ~2.4 `!` suppressions per 1k syntax nodes — 26 suppression(s) across the 10879 syntax node(s) in code where nullable warnings are ENABLED, which is the only code a `!` can suppress anything in (a `!` under `#nullable disable` is inert and is not counted, and its file's nodes are not in the denominator). Each one tells the compiler to trust you about null, suppressing the very safety NRTs provide.

Off the main sequence: CleanArchitecture.Contracts src/CleanArchitecture.Contracts/CleanArchitecture.Contracts.csproj:1 — CleanArchitecture.Contracts: abstractness 0.00, instability 0.00, distance 1.00 — the shape a shared-kernel / building-block library has BY DESIGN — concrete and widely depended-on is what makes it useful, and this dimension does not penalise it (the distance is reported for completeness, not as a defect). Worth a look only if it has grown past one coherent kernel into an everything-bucket.

Appendix B — Reproduction & audit trail

Every external tool invocation behind a deep-scan dimension — the tool, its captured version, the exact command, how many findings it yielded, and a link to the retained raw output. To reproduce any finding: check out the same commit and run the command shown (repo-relative — never an absolute scratch path). The complete raw scanner output is retained verbatim under artifacts/raw/ (indexed in artifacts/raw/index.json); per-invocation exit codes and wall-clock durations are in sidecar.json — kept out of this table so the rendered report stays byte-identical across runs of the same commit.

That is a clean result for the LEAK surface only: this ruleset detects personal data escaping, it does not inventory the personal data a repository holds, so it is not evidence that this repository has no personal-data surface. The personal-data map (Appendix C) and the C1-C5 compliance cards are what speak to that. semgrep could not parse 30 file(s) — `src/CleanArchitecture.Api/Controllers/RemindersController.cs`, `src/CleanArchitecture.Api/Controllers/SubscriptionsController.cs`, `REDACTED`, `src/CleanArchitecture.Application/Common/Behaviors/AuthorizationBehavior.cs`, `src/CleanArchitecture.Application/Common/Behaviors/ValidationBehavior.cs`, … (+25 more) — so the PII/GDPR sweep did not cover the unparsed regions of them; rows reported elsewhere in those files are real.	0	—

Appendix C — Personal-data map

Every field, property and record parameter whose name is conventional personal data — 25 field(s) across 2 categories, each with an exact repo-relative file:line. This is the data inventory a compliance review starts from — right-to-erasure, retention, minimisation. Detected by NAME, from the C# syntax tree, with a deliberately specific identifier classifier — the same one the C1–C5 compliance cards use to decide whether personal data is present, so CardDefinition or FileName don't trip. Two caveats stated rather than glossed: those cards additionally require corroboration (a persistence/account signal, or two distinct PII categories) that this inventory deliberately does not, so it lists more than they gate on; and D32 Data Compliance shares nothing with it — that dimension is a separate semgrep ruleset for personal data leaking into logs, URLs and browser storage, and a clean D32 result says nothing about this list. Informational — it feeds no score.
