Executive summary
fsprojects/Chessie scores 51 out of 100, which would normally be rated Adequate, but it is rated Weak because its weakest group of dimensions, Git mining, 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. The project hasn't declared a stable release yet, so its lenses are rated against a lower bar than a released product's, while the score itself is worked out as for any repository.
The weakest lens counts most in the score, and here that is Maturity, which scores 33 and is rated Weak. Its Knowledge Freshness dimension scores 0 out of 10, and until that reaches 4, Maturity can't be rated higher than Adequate. The first actions are to resolve the 1 Orphaned file finding(s) in Knowledge Freshness and to resolve the 1 Orphaned files with no living knowledge finding(s) in Knowledge Freshness, and if Maturity rose to 70, the score would rise from 51 to about 63.
No finding in this survey is critical.
Watchdog couldn't measure 36 dimensions in this code, among them Cyclomatic Complexity, Cognitive Complexity and Cohesion (LCOM4), so they are left out of the score. The product code is 339 lines.
If Maturity rose from 33 to 70, the lowest score rated Strong, the score would rise from 51 to about 63.
Rebuild cost: about €1,200 · Estimate
| Cost to rebuild | €410 to €2,000, for 7 to 21 hours of work, about 0.1 person-years for one engineer |
|---|---|
| Difficulty of the problem | Standard, 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 | ×0.7 at a score of 51. 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: 339 lines of product code |

Roadmap
Begin by resolving the orphaned files in the Knowledge Freshness dimension, specifically targeting ErrorHandling.fs and any other files lacking living knowledge. Next, enhance the value of existing comments to ensure they provide meaningful context rather than redundancy. Finally, establish a robust documentation foundation by recording significant design decisions in a dedicated ADR folder and expanding the README with clear getting-started instructions, an architecture overview, and a project map.
| Do this | Helps | Effort | Dimension |
|---|---|---|---|
| Resolve the 1 Orphaned file finding(s) in Knowledge Freshness — start with ErrorHandling.fs. | +14.5 pts | Low | Knowledge Freshness |
| Resolve the 1 Orphaned files with no living knowledge finding(s) in Knowledge Freshness. | +14.5 pts | Low | Knowledge Freshness |
| Improve Comment Value — currently 4.0/10. | +9.5 pts | Medium | Comment Value |
| 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. | +7.1 pts | Medium | Architecture documentation |
| Resolve the 2 Documentation finding(s) in Documentation Quality — start with README.md (2). | +3.2 pts | Low | Documentation Quality |
| Expand the README with getting-started, architecture overview and a project map. | +4.8 pts | Medium | Documentation (README) |
| Reconcile the README with reality: docs/content/index.md links to `railway.html`, but `docs/content/railway.html` does not exist; docs/content/index.md links to `reference/index.html`, but `docs/content/reference/index.html` does not exist. | +1.5 pts | Medium | Documentation accuracy |
| Run the test suite in CI via an explicit runner step (`dotnet test` for the toolchain this pipeline already uses) and gate merges on it. | +1.1 pts | Medium | CI/CD gates |

How the grades work
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.
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.
Recorded, with no effect on how the codebase functions. Present so the survey is complete, not because it needs doing.
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. 26 of 30 evaluated dimensions are computed purely by tools and static analysis (confidence 1.0); 4 documentation/naming judgement(s) are LLM-assisted and labelled advisory. Overall confidence is 0.7 — 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.
What we checked — 30 dimensions across the health lenses
- 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, 5 of 13 do; the remainder are repo-wide signals — a dimension-level measurement, not a single line.
- 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.

Run transparency — what happened this run
- D1 Cyclomatic Complexity — 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. Most of this repository's production source (.fs) had no cyclomatic complexity computed for it: no method bodies were exposed for those file kinds by any language model this pass could load.
- D2 Cognitive Complexity — 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. Most of this repository's production source (.fs) had no cognitive complexity computed for it: no method bodies were exposed for those file kinds by any language model this pass could load.
- D6 Cohesion (LCOM4) — 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. 3 of 3 class(es) with two or more methods were found, but the language model this pass loaded exposed none of their method bodies, so which method touches which field could not be seen.
- D10 Test Quality — 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. The 17 test(s) behind this row are the ones the C# collector could read, and this repository also carries at least 7 test source file(s) (.fs, .vb) that it cannot: it parses C# syntax and matches C# test attributes, so a vitest/jest/JUnit/pytest-style suite is invisible to it. Skipped tests, zero-assertion tests and the other quality signals on this row are UNMEASURED in that suite — their absence from the counts above is a gap in this analyzer's language coverage, not a finding that those tests are sound.
- D11 Test Reliability — 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. Test reliability NOT MEASURED: the test run produced no results for any test tier, so no test ever ran and flakiness could not be exercised. The cause could not be attributed, so it is excluded from the score rather than read as an absence of tests.
- D12 Dependency Hygiene — 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. `dotnet list package` did not return usable output (restore or query failed); no outdated/vulnerable/deprecated data to assess. The tool said: error: The value "" of the "Project" attribute in element <Import> is invalid. src/Chessie/Chessie.fsproj.
- D14 License Compliance — 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. Not scored — this repository's projects are MSBuild/NuGet projects, whose package licenses are exactly what this dimension reads, but no license could be resolved for them (the .NET license collector did not run, or restore failed). A gap in the analysis run, NOT a finding that the repository's licenses are compliant.
- D15 Churn × Complexity Hotspots — 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. A hotspot is churn × complexity. Churn was measured (76 line(s) across the 90-day window), but no complexity could be computed for .fs, which is most of this repository's production code — so every churned file would score as complexity 0 and the hotspot list would be empty no matter how tangled the code is. Not scored — this is a gap in the analysis run, not a finding about this repository.
- 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. Every one of the 1 significant source file(s) was last meaningfully changed so long ago that no living knowledge remains, so there is no concentration to measure — the bus factor is not scored. This is not a clean bill: nobody currently holds working knowledge of this code (see D34 Knowledge Freshness).
- D17 Explicit Debt — 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. The C# workspace loaded this repository's projects but reported a load failure, and the dead-code reference search is unreliable over a graph that did not load cleanly, so it was skipped. The other debt markers on this row were read; dead symbols were not, and their absence from the score is not a finding that the code has none. First load diagnostic: Failure: Cannot open project 'src/Chessie/Chessie.fsproj' because the file extension '.fsproj' is not associated with a language.
- D17 Explicit Debt — 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. The 0 deducted marker(s) and the 0.0/KLoC density on this row were taken over this repository's .NET projects ALONE: .fs (339 lines, 100% of production source) went unread, because every marker collector on this path is reached through a C# workspace. D17's marker collectors need a compiler we do not have for that language, so none of its nine marker kinds were read there. The debt in that source is UNMEASURED — its absence from the score above is a gap in this analyzer's language coverage, not a finding that the code carries none.
- D22 Internal API Consistency — 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. The loaded project set declares no packable project and no `.Contracts` project, so there is no intentionally-exposed surface for API consistency to be judged over.
- D39 IL Efficiency — 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. `dotnet build` exited 1 with a compiler/MSBuild diagnostic, so there were no assemblies to read IL from. The build itself is D18's row, with the ask; nothing further is charged here.
- D44 Platform End-of-Life — 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. This dimension reads a project's own statement about the platform it runs on: a TargetFramework in a .NET project file, a .nvmrc or .python-version, a capped requires-python, a Rust toolchain file or Cargo.toml rust-version, a .go-version, .java-version, .ruby-version, .tool-versions or .sdkmanrc, a go.mod go directive, a Maven or Gradle Java level or toolchain, a Gemfile's ruby directive, a mix.exs elixir requirement, a rebar.config minimum_otp_vsn, a pubspec.yaml SDK constraint, a build.sbt scalaVersion, or a framework major pinned by a dependency constraint. This repository carries none of them, so nothing about its platform was established. That is a gap in this analyzer's coverage, NOT a finding that the platform is supported — a language whose runtime is declared elsewhere (Package.swift, a Dockerfile) is simply not read here yet.
- AX2 Stateful singletons — 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. This check reads Microsoft.Extensions.DependencyInjection singletons in C#, Spring/JSR-330/CDI singletons in Java and Kotlin, module state in Python request handlers, handler state in Go and Swift, Play controllers, Cask routes, Scalatra servlets, Finatra controllers, Akka/Pekko HTTP routes and JSR-330 singletons in Scala, Rails, Sinatra, Grape, Roda and Hanami handlers and Rack apps in Ruby, and module state in F# request handlers (Giraffe, Saturn, Falco, Oxpecker and Suave handlers and ASP.NET Core controllers) only, and this repository's product is written in F#, which was left unread, so it had nothing of this repository's product to read. That is a gap in this analyzer's language reach — not a finding that the repository is free of what this check looks for.
- AX6 Interface segregation — 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. This check is computed over the public interfaces this run's compilations declare, and none was loaded, so it had nothing to read. That is a gap in this analyzer's language reach — not a finding that the repository is free of what this check looks for.
- C1 Data Protection — 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. These personal data controls are read from declarative annotations, request middleware, entity/column names and guard methods in a C# source model, and none was loaded on this run, so there was nothing to gather. That is a gap in this analyzer's language reach — not a finding that the repository lacks personal data controls.
- C2 Access Controls — 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. These authorization controls are read from declarative annotations, request middleware, entity/column names and guard methods in a C# source model, and none was loaded on this run, so there was nothing to gather. That is a gap in this analyzer's language reach — not a finding that the repository lacks authorization controls.
- C3 Audit Trail — 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. These audit controls are read from declarative annotations, request middleware, entity/column names and guard methods in a C# source model, and none was loaded on this run, so there was nothing to gather. That is a gap in this analyzer's language reach — not a finding that the repository lacks audit controls.
- C4 Data Retention — 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. These retention controls are read from declarative annotations, request middleware, entity/column names and guard methods in a C# source model, and none was loaded on this run, so there was nothing to gather. That is a gap in this analyzer's language reach — not a finding that the repository lacks retention controls.
- C5 Data-Subject Rights — 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. These data-subject rights controls are read from declarative annotations, request middleware, entity/column names and guard methods in a C# source model, and none was loaded on this run, so there was nothing to gather. That is a gap in this analyzer's language reach — not a finding that the repository lacks data-subject rights controls.
- P5 DR & Backup — 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. No backup/snapshot/replication config, RTO/RPO or restore-procedure documentation was found — and no production persistence was detected either (no data-access packages, no data-store services, no database resources), so there is nothing in this repository whose loss a DR control would recover. If this system's data lives in a platform or ops repo we can't see, that's where the DR evidence belongs.
- S1 Web-Security Posture — 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. These web-security controls are read from declarative annotations, request middleware, entity/column names and guard methods in a C# source model, and none was loaded on this run, so there was nothing to gather. That is a gap in this analyzer's language reach — not a finding that the repository lacks web-security controls.
- X1 Async correctness — 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. This check is implemented over the C# syntax tree, and no C# was loaded on this run, so it had nothing to read. That is a gap in this analyzer's language reach — not a finding that the repository is free of what this check looks for.

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.

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
- 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.
- 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.
- D13 Secret Scanning: Secret detection is signature- and entropy-based on the current tree — a secret that does not match a known pattern, or one already rotated, will not be flagged (a clean scan is "nothing matched", not "no secrets exist").
- 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.
- 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.
- 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.
- 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").
- 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.
- 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.
- 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.
- P6 Release Hygiene: Rollback/observability controls are inferred from repo artefacts (pipelines, dashboards-as-code) — controls configured in external tooling, with no in-repo trace, cannot be credited.
The LLM boundary
Dimensions
D3 · God Classes
0 god class(es) detected.
D4 · Code Duplication
0 duplicated block group(s) detected.
D5 · Coupling
1 projects, 0 dependency cycle(s), 0 unstable depended-on project(s).
What to do
- Enforce Coupling in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.
D9 · Test Distribution
17 test methods: 17 unit, 0 integration, 0 BDD, 0 e2e.
D10 · Test Quality
0 skipped, 0 zero-assertion, no mocking-framework packages referenced (hand-written doubles or no mocking) across 17 tests. Measured on the C# suite only — at least 7 test source file(s) (.fs, .vb) went unread, so its test quality is unmeasured and is not in these counts.
D13 · Secret Scanning
Secret scan ran and found no leaked secrets.
D17 · Explicit Debt
0 deducted debt markers + unmeasured dead symbols across 0 LoC in the .NET projects (0.0/KLoC) → score 10.0. Dead code not measured: the solution did not load cleanly, so the reference search was skipped. Measured on the .NET source only: .fs (100% of production source) was not read, and carries at least 0 uncounted task marker(s) in 0 file(s).
D19 · Documentation Quality
The repository's root README (Chessie) gives a strong overview and links to the project's documentation site while the lib/README is a directory-level placeholder. The docs content branch contains an excellent A Tale of 3 Nightclubs tutorial that explains what Chessie does with code examples, references, and a full outline; it is well-structured and complete for its audience. All four core documents (overview, installation, usage, contributing) are present in the root README but not shown due to truncation.
What to do
- Resolve the 2 Documentation finding(s) in Documentation Quality — start with README.md (2). — One of this dimension's main actionable groups (2 recommendation-level).
D21 · Naming Consistency
0 naming inconsistencies across 72 sampled symbols.
D24 · Comment Value
2 valuable / 0 redundant across 5 sampled comments.
What to do
- Improve Comment Value — currently 4.0/10. — 2 valuable / 0 redundant across 5 sampled comments.
D26 · Project Cohesion
0 of 1 projects flagged as possibly oversized/incoherent.
D28 · Secrets (history)
gitleaks scanned the full history AND the current working tree and found no secrets.
D29 · Static Analysis (SAST)
semgrep found no security issues.
D34 · Knowledge Freshness
1 of 1 significant source file(s) are orphaned — their living knowledge has decayed to nothing, so no one currently understands them. The largest is src/Chessie/ErrorHandling.fs. Counted over 1 of the 2 production source files in this repository: the rest are under the ~2,400-byte size floor this dimension measures over.
What to do
- Resolve the 1 Orphaned files with no living knowledge finding(s) in Knowledge Freshness. — One of this dimension's main actionable groups (1 recommendation-level).
- Resolve the 1 Orphaned file finding(s) in Knowledge Freshness — start with ErrorHandling.fs. — One of this dimension's main actionable groups (1 recommendation-level).

M1 · Documentation (README)
- The root README is 47 words, against a bar of 120. Of the three newcomer-critical sections this check looks for by heading, it found no a build/run or getting-started section, no a testing section, no an architecture or project-map section. Sections are matched on HEADING text only, so material written under a heading this check does not recognise — or with no heading at all — is not seen and this row may understate what the document covers.
What to do
- Expand the README with getting-started, architecture overview and a project map.
- Add a build/run (quick start) section to the root README — the first thing a newcomer needs.
- Explain in the README how to run the tests. Add a section called Testing to the README in the repository's top folder, saying how to run the test suite.
- Add an 'Architecture' / 'How it works' section to the root README — the high-level shape.
- Add a README to the 1 of 1 project(s) that lack one — worth up to 2 pts.
M2 · Architecture documentation
- 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.
M3 · Folder & project structure
M4 · Documentation accuracy
- docs/content/index.md links to `railway.html`, but `docs/content/railway.html` does not exist. Checked without a model against the repository: its files and folders, the scripts and dependencies of every package.json, the projects, namespaces, package references and target frameworks of the .NET build, the SDK and Node pins, and the identifiers of every file that is not a document; the documents' own text never counts. A footprint generated at build time, read only by a platform, or living outside this repository is not seen, and this row is then wrong. — docs/content/index.md:33
- docs/content/index.md links to `reference/index.html`, but `docs/content/reference/index.html` does not exist. Checked without a model against the repository: its files and folders, the scripts and dependencies of every package.json, the projects, namespaces, package references and target frameworks of the .NET build, the SDK and Node pins, and the identifiers of every file that is not a document; the documents' own text never counts. A footprint generated at build time, read only by a platform, or living outside this repository is not seen, and this row is then wrong. — docs/content/index.md:34
What to do
- Reconcile the README with reality: docs/content/index.md links to `railway.html`, but `docs/content/railway.html` does not exist; docs/content/index.md links to `reference/index.html`, but `docs/content/reference/index.html` does not exist.
P1 · CI/CD gates
- A CI pipeline exists but no test-runner invocation (your stack's test command, or a test job) was found — changes may merge without the suite running.
What to do
- Run the test suite in CI via an explicit runner step (`dotnet test` for the toolchain this pipeline already uses) and gate merges on it.
P3 · Security & performance tooling
- No static application security testing detected. For this repository's stack, add `semgrep --config=auto` plus gitleaks for committed secrets (F# is not a CodeQL language and has no language-specific SAST engine) as a CI step. What was searched, so you can tell an absence from a miss: the 1215 CI workflow file(s) in this repository, and the scanner and linter configuration checked in beside them. A scan that runs outside CI, one configured in your forge's web UI rather than in a committed file, or a tool whose name is none of those this check carries, is not seen — if that is your case the row is wrong, and saying so is more useful than adding a second scanner.
What to do
- Add a SAST step to CI running what this repository's stack ships: `semgrep --config=auto` plus gitleaks for committed secrets (F# is not a CodeQL language and has no language-specific SAST engine) — so a security regression fails the build instead of landing.
- Enable Dependabot/Renovate or a dependency-review gate.
- Add gitleaks/trufflehog in CI to block PRs that introduce committed secrets.

- AX1 Captive dependencies — Not applicable: this repository's F# imports no dependency-injection container and defines no container of its own — nothing that both registers and resolves bindings, and nothing that names two lifetimes — so nothing holds one lifetime's instance while handing out another's.
- AX2 Stateful singletons — not analysed — these correctness checks read a source model that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository
- AX5 Architecture & structure — not assessed — architecture style/structure is computed from a project graph (projects, types, module namespaces) that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository

- AX9 CQS / query purity — no CQRS query handlers detected — query purity is not applicable to this codebase
- AXB1 Runtime evidence locked — no reproducible boot — This repository has nothing the runtime tiers could boot or serve — no markup, no UI framework or web-server dependency, no UI component source, no native UI project and no API definition — nothing here is a surface to boot — so runtime a11y/egress/header evidence has no subject here. Not applicable: this is neither a gap in the scan nor a finding about your code.

- D1 Cyclomatic Complexity — cyclomatic complexity not measured — .fs exposed no member bodies
- D11 Test Reliability — Test reliability not measured — no test run produced results
- D12 Dependency Hygiene — Dependency hygiene not measured
- D14 License Compliance — Package licences not resolved for an MSBuild/NuGet repository
- D15 Churn × Complexity Hotspots — complexity unreadable for .fs — churn × complexity hotspots could not be measured
- D16 Bus Factor — dormant codebase — no living knowledge left to concentrate
- D18 Solution Shape — D18 scores the shape of a C#/VB .NET solution, but this repository's production source is mostly .fs, which the C#/VB workspace does not load — the projects that loaded are an immaterial minority, so solution shape was not assessed for this repository. Not scored — this is a gap in the analyzer's reach, not a verdict about this repository.
- D2 Cognitive Complexity — cognitive complexity not measured — .fs exposed no member bodies
- D20 ADR Quality — N/A — ADRs are expected on deployable products with a user-facing host, not consumed libraries; no ADR log is required here.
- D22 Internal API Consistency — No intentionally-exposed public API to evaluate for consistency.
- D23 Boundary Type-Coupling — small single-context codebase (339 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. 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
- D27 Navigability — No calls could be sampled, so navigability was not assessed — tracing effort is measured over resolved call sites and this target exposed none. Not scored — this is a gap in the analyzer's reach, not a verdict about this repository.
- D30 Dependency Vulnerabilities — nuget: the solution did not restore on the analyzer's .NET SDK (an SDK/target-framework/restore mismatch, common for an older codebase), so there was no restored dependency graph to scan
- D31 IaC & Container Security — No Infrastructure-as-Code or container manifests found (Dockerfile, Docker Compose, Terraform, Kubernetes/Helm, CloudFormation, ARM, Bicep, Ansible); nothing to scan.
- D32 Data Compliance (PII/GDPR) — No personal data was found crossing a boundary the PII/GDPR ruleset checks — nothing written to a log or console sink, placed in a URL or query string, or persisted to browser storage. 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.
- D36 Supply-chain Provenance & Signing — The CI pipeline builds and tests but publishes no released artifact — no package publish, container push, GitHub release or deployment step. Supply-chain provenance, signing and SBOM attest RELEASED artifacts, so there is nothing to attest here. Add them to the release pipeline when this repo starts shipping artifacts (a published package, a container image, a deployed service or a tagged release). Build integrity and workflow-token hygiene are reported below: they describe what the CI runs and the token it runs with, neither of which is affected by whether the pipeline ships an artifact.
- 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.
- D39 IL Efficiency — IL not measured — the target did not build
- 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).
- D44 Platform End-of-Life — Platform end-of-life not assessed — this repository declares no platform this pass reads
- D6 Cohesion (LCOM4) — cohesion (LCOM4) not measured — the code model exposed no member bodies
- D7 Architectural Integrity — no checkable ADRs and no dependency cycles — architectural integrity not assessed
- D8 Code Coverage — Coverage NOT MEASURED: `--collect:"XPlat Code Coverage"` names a data collector that ships in the `coverlet.collector` package, and this repository wires up none — no test project references it and no runsettings declares one. The absence of coverage here is therefore not evidence about the suite or about our analyzer environment: without a collector, `--collect` produces nothing even from a suite that builds and passes. Add a `coverlet.collector` PackageReference to the test project(s) (or commit the Cobertura/OpenCover/lcov report your CI produces) and real coverage will be measured. It is excluded from the score rather than counted as a near-zero defect.
- DM1 Domain Modelling — not scored — this repository shows only 1 of the 3 signals this lens looks for (3 value object(s))
- ED1 Event-Driven — not scored — this repository shows none of the 3 signals this lens looks for
- ED5 Idempotency — no mutating command handlers or message consumers detected — idempotency check not applicable
- ES1 Event Sourcing — not scored — this repository shows none of the 3 signals this lens looks for
- IC1 Incompleteness & stubs — reported, not scored — this repository's C# declares no analysable method bodies (a constants, record or DTO assembly), and this score is a density of unfinished work per method, which has no denominator here. The file-level signals below were still collected and are shown in full
- P12 CI test-gate honesty — Reported, not scored — and nothing was matched here. The coverage check applies to any stack, and the automatic-re-run check to any GitHub-Actions workflow, but the checks for excluded tests, skipped tests and sleep-based synchronisation currently recognise only some ecosystems' test-runner idioms, so on a repository built with another stack the zeros below mean 'not checked', not 'clean'.
- P2 Observability — This repository's F# source (1 module(s), 2 file(s) read) declares no entry point and bootstraps no server, and nothing here deploys a service — it is a library, run inside whatever hosts it, so production observability (structured logging, tracing/metrics, health checks) is N/A. If it grows a binary or a service, the dimension reactivates.
- P7 Outbound HTTP resilience — not measured — the application kind could not be determined for this repo
- P8 Schema migrations — no EF Core usage detected
- P9 Domain vs controller coverage — no coverage report found on disk — produce a coverage report in a standard format (Cobertura — `dotnet test --collect:"XPlat Code Coverage"` with a `coverlet.collector` PackageReference) and commit it — a hosted scan measures a clone of the repository, so a report that exists only in a working tree, a CI runner's or your own, never reaches it; the artefact is commonly gitignored, so `git add -f` that one file (or un-ignore its path) and commit it alongside the code it measures, or wire coverage collection into CI, to enable this cross-layer check
- PF1 Benchmark discipline — Not applicable: no benchmark suite was found. This check searched for a BenchmarkDotNet reference in an .fsproj or .vbproj, and for a `*benchmark*` script that this repository's CI runs. Benchmarks are credited as a bonus, so their absence is neither scored nor deducted.
- PF2 Allocation hygiene — Not applicable: allocation awareness is rated where code engineers for it — at least 400 production lines that ship benchmarks or already use allocation-aware idioms (8 or more). This repository's F# code has 407 production line(s), 0 such use(s) and no benchmarks, so there is no allocation work to rate. The card is reward-only: its absence costs nothing.
- PF3 Async & latency hygiene — Not applicable: this repository declares no async functions, so there is no asynchronous code for a blocking call to stall.
- S1 Web-Security Posture — Not assessed: these web-security controls are read from a source model (declarative annotations, request middleware, entity/column names, guard methods) that was not loaded for this repository — because the repository is written in a language this check does not yet model, or because its projects failed to load. Absence of an idiom this check recognises is NOT evidence that this repository lacks web-security controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
- X1 Async correctness — not analysed — these correctness checks read a source model that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository
- X10 Duplicated predicate — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
- X12 Unreachable branch — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X13 Undrained process stream — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X14 Bypassable address classification — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X15 Unvalidated length from an untrusted reader — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X16 Unfloored truncation loop — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X17 Uncapped recursion over a caller-supplied document — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X18 Disposal-pattern correctness — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X19 Unrestored process-global state — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X2 Cancellation propagation — not analysed — these correctness checks read a source model that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository
- X21 Side-effecting pattern guard — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X22 Contradicted release guard — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X24 Document value interpolated into markup unescaped — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X25 Inert configuration knob — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X26 Unsynchronised callback handoff — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X29 Per-element action decided by a fixed element — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X3 Exception handling — not analysed — these correctness checks read a source model that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository
- X30 Support guard that admits what it rejects — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X32 Type resolved by simple name across every loaded assembly — This check reads C# syntax; no C# was loaded for this repository, so it has nothing to report. That is a limit of the analyzer, not a finding about your code.
- X4 Structured logging — not analysed — these correctness checks read a source model that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository
- X5 Nullable reference types — not analysed — these correctness checks read a source model that was not loaded for this repository, because the repository is written in a language this check does not yet model, or because its projects failed to load. This is a gap in the analyzer, not a finding about this repository
- X9 Subsumed condition operand — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.

| D30 · Dependency Vulnerabilities | nuget | — | nuget: not applicable — nuget: the solution did not restore on the analyzer's .NET SDK (an SDK/target-framework/restore mismatch, common for an older codebase), so there was no restored dependency graph to scan | 0 | — |
| D31 · IaC & Container Security | trivy | — | trivy: not applicable — No Infrastructure-as-Code or container manifests found (Dockerfile, Docker Compose, Terraform, Kubernetes/Helm, CloudFormation, ARM, Bicep, Ansible); nothing to scan. | 0 | — |
| D32 · Data Compliance (PII/GDPR) | semgrep | — | semgrep: not applicable — No personal data was found crossing a boundary the PII/GDPR ruleset checks — nothing written to a log or console sink, placed in a URL or query string, or persisted to browser storage. 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. | 0 | — |
| D37 · Vulnerability-disclosure Policy | disclosure | — | disclosure: not applicable — 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. | 0 | — |
| D40 · Network Egress Confinement | runtime-hardening | — | runtime-hardening: not applicable — 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. | 0 | — |
| D41 · Kernel & Syscall Confinement | runtime-hardening | — | runtime-hardening: not applicable — 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. | 0 | — |
| D42 · Runtime Threat Enforcement | runtime-hardening | — | runtime-hardening: not applicable — 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. | 0 | — |
| D43 · Malicious Dependencies | none (no readable dependency manifest) | — | none (no readable dependency manifest): not applicable — 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). | 0 | — |
