Executive summary
Preview (pre-1.0). This repo hasn't declared a stable release, so it's judged against a relaxed, pre-production bar.
This system holds a strong overall standing of 66%, reflecting a well-engineered core that is currently limited by operational maturity. While the codebase is small and inexpensive to rebuild, the primary business risk lies in its ability to be understood and maintained by teams over time. The architecture is robust, but the lack of documented context creates a hidden dependency on tribal knowledge, which threatens long-term delivery speed and increases the cost of future changes.
The value at stake is modest, with a rebuild cost of approximately €8,000. This low barrier to entry means the system is not a legacy burden, but it also means there is little excuse for allowing operational gaps to persist. The code itself is clean and highly maintainable, with excellent architectural integrity and strong security practices. However, the maturity lens reveals a significant gap: without clear records of why decisions were made, new engineers will struggle to navigate the system, leading to slower onboarding and a higher risk of introducing defects during modifications.
The most critical theme is the concentration of risk in documentation and decision history. While the code is technically sound, the absence of recorded context means that business logic and design choices are not transferable. This creates a fragility where key knowledge resides only in the heads of current team members. If those individuals leave, the cost of maintaining or extending the system rises sharply. Addressing this is not about rewriting code, but about capturing the institutional memory that allows the team to move fast without fear.
To maximize leverage, the immediate focus should be on recording significant decisions in a centralized, discoverable format. This single action provides the highest return on effort by stabilizing the team’s ability to make informed changes. Adding a testing guide to the main documentation and implementing a draft release gate are secondary but necessary steps to ensure safe operations. By prioritizing these low-cost, high-impact improvements, the organization can transform a technically strong but context-poor asset into a resilient, self-sustaining component of the business.

Roadmap
Begin by establishing a central repository for architecture decisions and adding a testing section to the root README to clarify how to run the suite. Next, implement a draft release gate to prevent bad builds from reaching users and maintain a changelog to track what ships in each release. Finally, enhance the documentation quality by expanding the README to cover installation, usage examples, and contribution guidance.
| Do this | Helps | Effort | Dimension |
|---|---|---|---|
| Record significant decisions one document per decision — dated, stating the context, the decision and its consequences — and keep them together wherever your design docs already live (a conventional `docs/adr/` tree, with each file named `NNNN-title` in whatever markup those docs already use, is the most discoverable form). | +10.8 pts | Medium | Architecture documentation |
| Add a 'Testing' section to the root README — how to run the test suite. | +10.0 pts | Medium | Documentation (README) |
| Nothing pauses a release for a human: publish as a draft release (or gate the release job on a protected tag/manual dispatch) so a bad build can be stopped before users can download it. | +6.3 pts | Medium | Deployment & Rollback |
| Keep a changelog (e.g. Keep-a-Changelog) recording what shipped in each release. | +6.3 pts | Medium | Release Hygiene |
| Improve Documentation Quality — currently 8.0/10. | +4.6 pts | Medium | Documentation Quality |
| Resolve the 1 Orphaned files with no living knowledge finding(s) in Knowledge Freshness. | +1.7 pts | Low | Knowledge Freshness |
| Give Benchee a `memory_time:` (e.g. `memory_time: 2`) so each job's memory usage is measured beside its run time and allocation regressions are visible. | +1.0 pts | Medium | Benchmark discipline |
| Resolve the 1 REDACTED finding(s) in Supply-chain Provenance & Signing. | +0.3 pts | Low | Supply-chain Provenance & Signing |

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. 32 of 35 evaluated dimensions are computed purely by tools and static analysis (confidence 1.0); 3 documentation/naming judgement(s) are LLM-assisted and labelled advisory. Overall confidence is 0.9 — 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 — 35 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, 43 of 60 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
- D4 Code Duplication — 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 1 duplicated block group(s) on this row were found in the languages this pass could tokenize, and they do NOT cover all of this repository's production source: .c (3,807 lines, 43% of production source) went unread, because no language model this pass could load exposed a clone-unit token stream for those file kinds. Duplication in that source is UNMEASURED — its absence from the count above is a gap in this analyzer's language coverage, not a finding that the code is free of duplication.
- D8 Code Coverage — 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. Coverage NOT MEASURED: test source is present (.exs) but the built-in coverage collector has no runner for this repository's ecosystem — so this suite was never executed by it. Not scored — this is a gap in the analyzer's language coverage, not a defect in the repo. To have real coverage read, produce a coverage report in a standard format (lcov — `mix test --cover` with `excoveralls` (`mix coveralls.lcov`)) 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. You can widen what we reach: optional: produce a coverage report in a standard format (lcov — `mix test --cover` with `excoveralls` (`mix coveralls.lcov`)) 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 — then the real number is read on the next scan.
- 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 source is present (.exs) but the built-in reliability runner does not support this repository's ecosystem, so flakiness couldn't be assessed. Not scored — this is a gap in the analyzer's language coverage, 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. Single-maintainer repository — bus factor is not applicable (16 contributor(s) across 552 commit(s) sampled, automation and bot accounts excluded). One of them holds 87% of the history; the other 15 hold 0.9% 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.
- D22 Internal API Consistency — 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. D22 identifies the intentionally-exposed surface from `IsPackable` and `.Contracts` project names, MSBuild conventions read off the loaded project set. This target exposed no such projects, so the probe never ran; this says nothing about whether the repository has a public API. This repository commits no C#/VB source at all, so there was never an MSBuild project set to read these conventions off. That is OUR side and it is a COLLECTOR gap, not an environment fault: it declares a published package (mix.exs), but no published-package marker D22 reads admitted any project here, so this ecosystem's public API has no collector, and the remedy is to write one — no change to the scan image can close it.
- D26 Project Cohesion — 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. Project size and spread are measured over build units whose source a code model reads. This repository's .c source is a material share of its production lines and was read by none, so the score is a verdict about the units that were read. Not a finding that the unread source is cohesive — it is unmeasured.
- D27 Navigability — 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. Navigability is taken over call sites whose callee resolved. For C# that population includes calls into referenced assemblies; for this language only calls declared inside the repository count, so the abstention threshold reads the repository's use of its standard library as a resolution failure. That is a limit of this analyzer, not a build problem in this repository.
- 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.
- GD1 Unfinished & placeholder code — 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 C# syntax, F#, JavaScript/TypeScript, Dart, Ruby and Scala source only, and no C#, F#, JavaScript/TypeScript, Dart, Ruby or Scala was found, and this repository's Elixir, c is not read yet, 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.
- IC1 Incompleteness & stubs — 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 C# syntax, JavaScript/TypeScript, Java, Dart, Ruby and Scala source only, and no C#, JavaScript/TypeScript, Java, Dart, Ruby or Scala was found, and this repository's Elixir, c is not read yet, 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.
- 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.
- P8 Schema migrations — 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 EF Core usage in C# and the schema tooling its file scan recognises only, and no .NET project was loaded, and this repository's language is not one the scan models, 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.
- 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 reads C# syntax, and JavaScript/TypeScript, Python, Dart, Ruby, Scala, Rust and Kotlin source only, and no C# was loaded and no JavaScript/TypeScript, Python, Dart, Ruby, Scala, Rust or Kotlin was found in this repository, 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.
- X12 Unreachable branch — 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 C# syntax, and JavaScript/TypeScript, Python, Dart, Ruby, Scala and Kotlin source only, and no C# was loaded and no JavaScript/TypeScript, Python, Dart, Ruby, Scala or Kotlin was found in this repository, 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.
- X13 Undrained process stream — 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 C# syntax, and JavaScript/TypeScript, Python, Dart, Ruby, Scala and Kotlin source only, and no C# was loaded and no JavaScript/TypeScript, Python, Dart, Ruby, Scala or Kotlin was found in this repository, 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.
- X14 Bypassable address classification — 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 C# syntax, and JavaScript/TypeScript, Java, Kotlin, Scala, Rust, Swift, Ruby, Dart, PHP, Python and Go source only, and no C# was loaded and no JavaScript/TypeScript, Java, Kotlin, Scala, Rust, Swift, Ruby, Dart, PHP, Python or Go was found in this repository, 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.

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
- 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.
- 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.
- 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 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").
- 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.
- 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.
- 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").
- 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.
- 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.
- D43 Malicious Dependencies: Only packages some vulnerability database has already NAMED as malicious are seen — a compromise published in the last hours, or never reported at all, is invisible here, and this dimension reading 10 is not evidence that a dependency is trustworthy. There is no typosquat or dependency-confusion analysis: a package nobody has reported is simply absent from the feeds. Coverage is the dependency scan's: an ecosystem that could not be scanned is disclosed as unmeasured, never as clean.
- 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 Dockerfile (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.
- M4 Documentation accuracy: Onboarding quality is an LLM read of the docs/setup present — it cannot run the onboarding or measure how long a real new joiner takes; the verdict is sampled and advisory.
- P4 Deployment & Rollback: Approval/branch-protection rules live in repository settings the scan cannot see — only their in-repo evidence (config files, workflows) is checked, so a control enforced purely in the host's settings reads as "not evidenced".
- P6 Release Hygiene: Rollback/observability controls are inferred from repo artefacts (pipelines, dashboards-as-code) — controls configured in external tooling, with no in-repo trace, cannot be credited.
The LLM boundary
Dimensions
D1 · Cyclomatic Complexity
0 function(s) exceeded the cyclomatic complexity threshold of 15. A further 1 function(s) were over the threshold but excluded as flat dispatchers (a long switch/match over independent cases: many branches, almost no nesting), the largest being Image.interpretation at 22 — they are counted neither in the figure above nor in this dimension's score. 1 file carries no cyclomatic complexity row at all for this reason — every one of its over-threshold functions was excluded, so the exclusion is disclosed nowhere in the file itself: lib/vix/vips/image.ex (Image.interpretation at 22). They are named here because the per-file figures other dimensions report are taken BEFORE this exclusion, so such a file can show a high maximum complexity elsewhere in this report and nothing here, with nothing to reconcile the two.
D2 · Cognitive Complexity
0 function(s) exceeded the cognitive complexity threshold of 15.
D3 · God Classes
4 over-large unit(s) detected — types, modules or files that carry too much.
What to do
- Resolve the 2 TooManyFunctions finding(s) in God Classes — start with nif.ex, helper.ex. — One of this dimension's main actionable groups (2 warning-level).
- Resolve the 2 FileTooLong finding(s) in God Classes — start with operator.ex, image.ex. — One of this dimension's main actionable groups (2 warning-level).
- Enforce God Classes in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.
D4 · Code Duplication
1 duplicated block group(s) detected. Measured on part of this repository only: .c (43% of production source) was not exposed to the token comparison, so duplication there is unmeasured and is not in this count.
What to do
- Resolve the 1 Duplicated block (5 lines × 2) finding(s) in Code Duplication — start with source_pipe.ex. — One of this dimension's main actionable groups (1 warning-level).
- Enforce Code Duplication in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Verified — provenance only; does not change the score.
D6 · Cohesion (LCOM4)
0 of 6 classes have LCOM4 above 3.
D12 · Dependency Hygiene
5 outdated, 0 retired direct Hex dependencies, 0 pinning defect(s). Whether any of these packages is UNMAINTAINED is not graded — hex.pm publishes no maintenance status, and release age does not stand in for one. Whether any is UNUSED is not graded either: a Hex app name does not determine the modules it provides (`ecto_sql` provides Ecto.Adapters.SQL), and a large idiomatic class of BEAM dependencies — runtime adapters, codec plugins, protocol implementations and OTP applications the release starts — is correctly declared and never referenced in source, so absence of a reference is not evidence of an unused dependency. Known CVEs in this dependency graph are D30's question, read from mix.lock there.
D13 · Secret Scanning
Secret scan ran and found no leaked secrets.
D14 · License Compliance
0 of 9 shipped Hex package(s) use a banned license. Licences were resolved from hex.pm over the packages a consumer installs — this repository's mix.lock closed over the declarations its mix.exs files do not gate behind `only:`. Packages it asks for ONLY under `only: [:dev, :test]` (or any other non-prod environment, such as `:docs`) are excluded: they are not installed by anything that depends on this repository. Each licence is the one hex.pm publishes for the package's current release. This repository publishes itself under MIT, which is its own choice and is not judged here.
D15 · Churn × Complexity Hotspots
No churn × complexity hotspots in the window.
D17 · Explicit Debt
6 deducted task-comment markers across 5489 LoC (0.1/KLoC) → score 9.8. Task comments only: this repository's language is read without a compiler, so D17's suppression, dead-code and commented-out-code arms did not run and this score counts fewer marker kinds than a .NET repository's would.
What to do
- Resolve the 6 TodoComment finding(s) in Explicit Debt — start with type.ex (2), tensor.ex, string.ex. — One of this dimension's main actionable groups (6 warning-level).
- Enforce Explicit Debt in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.
D19 · Documentation Quality
The repository's root README is clear and complete: it states the project name (Vix), its purpose (blazing fast image processing for Elixir powered by libvips), a CI badge, a Hex.pm badge, and a docs badge; lists five perfect-for-use cases; enumerates seven features; provides a runnable Quick Start with aliases and code that runs in Livebook; and outlines every visible section of the architecture/operation documentation (Vix; Perfect For; Features; Quick Start; Common Operations) under an exhaustive heading. It is well written for an overview document, but it does not yet cover installation, usage examples beyond the quick start, or contribution guidance.
What to do
- Improve Documentation Quality — currently 8.0/10. — The repository's root README is clear and complete: it states the project name (Vix), its purpose (blazing fast image processing for Elixir powered by libvips), a CI badge, a Hex.pm badge, and a docs badge; lists five perfect-for-use cases; enumerates seven features; provides a runnable Quick Start with aliases and code that runs in Livebook; and outlines every visible section of the architecture/operation documentation (Vix; Perfect For; Features; Quick Start; Common Operations) under an exhaustive heading. It is well written for an overview document, but it does not yet cover installation, usage examples beyond the quick start, or contribution guidance.
D21 · Naming Consistency
0 naming inconsistencies across 0 sampled symbols.
D26 · Project Cohesion
0 of 1 build units (Mix) flagged as possibly oversized/incoherent. This repository's .c source was read by no build unit, so this covers part of the tree, not all of it.
D28 · Secrets (history)
gitleaks scanned the full history AND the current working tree and found no secrets.
D29 · Static Analysis (SAST)
30 finding(s): 0 critical, 30 high, 0 medium, 0 low. 30 unpinned-GitHub-Actions row(s) are reported here but scored by D36 (supply-chain provenance), which measures that posture as `pinned_actions` — one pinning decision is charged once, not once per lens. semgrep hit a parse error in 2 file(s) — `c_src/vips_foreign.c` (line 303), `c_src/vips_image.c` (line 86, line 334, line 968) — 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.
What to do
- No action in Static Analysis (SAST) — all 30 REDACTED finding(s) are reported here at file:line but scored by D36 (supply-chain provenance), so none is charged to this dimension. — One of this dimension's main actionable groups (30 issue-level, 0 of them charged here).
D30 · Dependency Vulnerabilities
No known-vulnerable dependencies in any ecosystem this repository declares.
D34 · Knowledge Freshness
1 of 14 significant source file(s) are orphaned — their living knowledge has decayed to nothing, so no one currently understands them. The largest is .credo.exs. Counted over 14 of the 37 production source files in this repository: the rest are under the ~2,400-byte size floor this dimension measures over.
D35 · Change Coupling
Strongest change-coupling: precompiler.exs↔mix.exs 53%
What to do
- Resolve the 1 Change coupling finding(s) in Change Coupling — start with precompiler.exs. — One of this dimension's main actionable groups (1 warning-level).
D36 · Supply-chain Provenance & Signing
0/4 supply-chain integrity signals present (provenance, signing, SBOM, pinned actions).
What to do
- Resolve the 1 REDACTED finding(s) in Supply-chain Provenance & Signing. — One of this dimension's main actionable groups (1 warning-level).
- Resolve the 1 REDACTED finding(s) in Supply-chain Provenance & Signing. — One of this dimension's main actionable groups (1 warning-level).
- Resolve the 1 REDACTED finding(s) in Supply-chain Provenance & Signing. — One of this dimension's main actionable groups (1 recommendation-level).
D43 · Malicious Dependencies
No dependency in any ecosystem this repository declares is published as malicious.
D44 · Platform End-of-Life
0 end-of-life runtime(s) and 0 end-of-life framework(s), read from 1 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.
Frontend & cross-cutting dimensions
AX10 · Code composition
What to do
- The domain core is a small share of production code, but most of the rest matched no layer vocabulary at all — so this is not yet an anemic-domain finding. The namespace/path convention could not place that code, which makes the composition above a statement about the naming, not about the design. Name the layers (or check that the repository's conventions differ from the ones this check knows) before reading a thin domain into it.
AX3 · Project dependency cycles
AX4 · Dependency direction
M1 · Documentation (README)
What to do
- Add a 'Testing' section to the root README — how to run the test suite.
- Add an 'Architecture' / 'How it works' section to the root README — the high-level shape.
- Add a README to the 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.
- No C4/Structurizr/PlantUML/Mermaid/Graphviz/D2 diagram, no drawn diagram named for the architecture, no file named `architecture` or `design` in any markup this check reads, and nothing in the README, docs or contributor guides that announces the shape — no `## Architecture` heading, no "architecture overview"/"high-level design" phrasing, no "the architecture is …" introduction, no guided code tour. A shape laid out in prose that never names itself as the architecture is not visible to this check, and neither is one kept outside the repository, so this row reports the absence of a re-findable shape document — not evidence that nobody wrote the shape down.
What to do
- Record significant decisions one document per decision — dated, stating the context, the decision and its consequences — and keep them together wherever your design docs already live (a conventional `docs/adr/` tree, with each file named `NNNN-title` in whatever markup those docs already use, is the most discoverable form).
- Add a C4 context/container diagram (Structurizr, PlantUML or Mermaid) or an architecture.md overview.
M3 · Folder & project structure
M4 · Documentation accuracy
P1 · CI/CD gates
P10 · Library API & versioning
P3 · Security & performance tooling
What to do
- Enable Dependabot/Renovate or a dependency-review gate.
- Add gitleaks/trufflehog in CI to block PRs that introduce committed secrets.
P4 · Deployment & Rollback
- The release 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 the release trigger points at is published to users unreviewed, so a mistagged or unverified commit ships and the only remedy is a follow-up release.
What to do
- Nothing pauses a release for a human: publish as a draft release (or gate the release job on a protected tag/manual dispatch) so a bad build can be stopped before users can download it.
P6 · Release Hygiene
- No CHANGELOG/HISTORY/RELEASES file — what shipped when isn't easy to reconstruct for support or audit. (Versioning/tagging makes releases traceable, but a changelog records the what.)
What to do
- Keep a changelog (e.g. Keep-a-Changelog) recording what shipped in each release.
PF1 · Benchmark discipline
- A Elixir Benchee/Benchfella suite exists but nothing turns on its allocation measurement — allocations (the main way hot code pressures a garbage collector or allocator) aren't being measured. — bench/to_stream.exs
What to do
- Give Benchee a `memory_time:` (e.g. `memory_time: 2`) so each job's memory usage is measured beside its run time and allocation regressions are visible.

Not evidenced — 1 control(s) we could not find positive evidence for
- P5 DR & Backup — not evidenced — repo shows no backup/RTO/RPO controls; absence of evidence is not evidence of a working control
Not included — 84 check(s) not relevant to this codebase
- AC1 Text alternatives — No web markup found — accessibility is not applicable to this repository.
- AC2 Forms & labels — No web markup found — accessibility is not applicable to this repository.
- AC3 Page structure — No web markup found — accessibility is not applicable to this repository.
- AC4 Keyboard semantics — No web markup found — accessibility is not applicable to this repository.
- AC5 ARIA correctness — No web markup found — accessibility is not applicable to this repository.
- AC6 Visual & motion safety — No web markup found — accessibility is not applicable to this repository.
- AC7 A11y enforcement — No web markup found — accessibility is not applicable to this repository.
- AX1 Captive dependencies — Not applicable: the BEAM has no dependency-injection container — state lives in processes, and no process is handed an instance whose lifetime another one scopes.
- AX2 Stateful singletons — Not applicable: Elixir processes share no mutable memory — state lives in a process's own mailbox — so there is no shared object to race on.
- 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
- AX6 Interface segregation — not assessed — interface segregation is computed over a type surface 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
- AX7 Slice cohesion — not applicable — not a vertical-slice architecture
- AX8 Test isolation — no test/production split to check
- 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.
- AXB2 Runtime readiness — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
- C1 Data Protection — No personal data detected in a persisted data model — no PII-named field (email, first_name, date_of_birth, phone, …) or stored credential in an Ecto schema, an Ecto migration or an Ash resource — and no database or data-store client (an Ecto repo, Postgrex, MyXQL, Exqlite, Mongo, Mnesia, …) in the source either, so this repository keeps no data at rest for these controls to protect.
- C2 Access Controls — No access-control surface detected in the analyzed source — this repository starts no server another machine can reach (no Phoenix.Endpoint, Plug.Cowboy or Bandit child). Access control is therefore N/A here — a library or OTP application is authorized by the application that serves it, not by itself. If this codebase grows request handlers, the dimension reactivates and a default-deny posture is expected then.
- C3 Audit Trail — No personal data detected in a persisted data model — no PII-named field (email, first_name, date_of_birth, phone, …) or stored credential in an Ecto schema, an Ecto migration or an Ash resource — and no database or data-store client (Ecto, Postgrex, MyXQL, Mongo, EventStore, …) in the source either, so this repository keeps no sensitive data whose changes an audit trail would record. If it does (through a store configured outside this repository, for instance), the trail belongs to wherever that data is stored.
- C4 Data Retention — No personal data detected in a persisted data model — no PII-named field (email, first_name, date_of_birth, phone, …) or stored credential in an Ecto schema, an Ecto migration or an Ash resource — and no database or data-store client (an Ecto repo, Postgrex, MyXQL, Exqlite, Mongo, Mnesia, …) in the source either, so this repository keeps no personal data whose lifetime a retention limit would bound.
- C5 Data-Subject Rights — No personal data detected in a persisted data model — no PII-named field (email, first_name, date_of_birth, phone, …) or stored credential in an Ecto schema, an Ecto migration or an Ash resource — and no database or data-store client (an Ecto repo, Postgrex, MyXQL, Exqlite, Mongo, Mnesia, …) in the source either, so this repository keeps no personal data for a data subject to erase, export or consent over.
- D10 Test Quality — ~1217 lines of test source are present (.exs) but no test cases reached the test census for this repository — no test root we could resolve declared them, or the files we read declare no cases in a test framework we recognise — so skipped/assertion-free tests couldn't be counted. Not scored — this is a gap in the analyzer, not a finding about this repository.
- D11 Test Reliability — Test reliability not included — no .exs test runner
- D16 Bus Factor — single-maintainer repository — bus factor is not applicable
- D18 Solution Shape — D18 scores the shape of a .NET solution; this repository has no .NET solution or project files, so the dimension does not apply.
- 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 — The exposed public-API surface could not be collected — no C#/VB projects loaded.
- D23 Boundary Type-Coupling — No bounded-context organisation was detected either — neither a context-shaped layout nor 2+ sibling source directories each declaring an aggregate root. 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"]`.
- D24 Comment Value — No inline comments to assess — comment value is not applicable here.
- D25 ADR Conformance — no ADRs to check
- D27 Navigability — D27 counts a call into the standard library or a dependency as unresolved for this repository's language (.ex,.exs), so too few call sites counted as resolved to assess navigability. Not scored: this is a gap in the analyzer, not a verdict about this repository.
- 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.
- 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 — D39 measures the IL emitted by a .NET build; this repository has no .NET solution or project files, so the dimension does not apply.
- D40 Network Egress Confinement — No Kubernetes/orchestration workloads found in the repository manifests; network egress policy is a cluster-native control that may live at the platform/firewall layer, so there is nothing to assess here.
- D41 Kernel & Syscall Confinement — No Kubernetes/orchestration workloads found in the repository manifests; seccomp/AppArmor/SELinux confinement is a workload-level control, so there is nothing to assess here.
- D42 Runtime Threat Enforcement — No Kubernetes/orchestration workloads found in the repository manifests; runtime threat-detection and admission-control policy are cluster-level controls, so there is nothing to assess here.
- D5 Coupling — Not applicable — this OTP build ships 1 production module(s), so there is no coupling BETWEEN modules to measure. (Its test and non-production modules are not part of the shipped graph.)
- D7 Architectural Integrity — no checkable ADRs, and no project-reference graph for the cycle pass to read — so this dimension makes no claim about dependency cycles in either direction (where this repository's language has an import-cycle lens, cycles are reported there). Architectural integrity not assessed
- D8 Code Coverage — Coverage not included — suite not readable by the collector
- D9 Test Distribution — Test source is present (.exs) but no test cases reached the test census for this repository — no test root we could resolve declared them, or the files we read declare no cases in a test framework we recognise — so its unit/integration/BDD/E2E split couldn't be counted. Not scored — this is a gap in the analyzer, not a finding about this repository.
- DM1 Domain Modelling — not scored — this repository shows only 1 of the 3 signals this lens looks for (2 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
- GD1 Unfinished & placeholder code — no source files were read — this check reads C#, F#, JavaScript/TypeScript, Dart, Ruby and Scala, and none was read for this repository's product. That is a limit of the analyzer, not a finding about your code.
- IC1 Incompleteness & stubs — 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
- 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 Elixir source (1 module(s), 31 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 applicable — no HTTP server, API framework or worker entry point was found in the Elixir source, so there is no service whose uptime a failing dependency could take down
- P8 Schema migrations — 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
- P9 Domain vs controller coverage — no coverage report found on disk — produce a coverage report in a standard format (lcov — `mix test --cover` with `excoveralls` (`mix coveralls.lcov`)) 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
- PF2 Allocation hygiene — Not applicable: Elixir runs on a garbage-collected runtime that gives a program no allocation-control idiom to choose on a hot path — no pools, stack allocation or value types — so allocation awareness is not something this code can be rated on.
- PF3 Async & latency hygiene — Not applicable: Elixir has no async/await function colour, so there is no asynchronous code for a blocking call to stall.
- S1 Web-Security Posture — No web surface: 28 Elixir file(s) were read for weak hashes and ciphers, key material fixed in the source, disabled TLS certificate validation and obsolete TLS versions, and none was found. This repository serves no HTTP of its own — no Phoenix, Plug, Cowboy, Bandit or Thousand Island among its `mix.exs` dependencies outside a test- or dev-only scope, and no endpoint or server started in its production source — so HTTPS enforcement, HSTS, cookie flags and input validation are N/A here, as they are for a C# library or worker. If this codebase starts serving HTTP, the dimension reactivates automatically.
- 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 — 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
- X13 Undrained process stream — 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
- X14 Bypassable address classification — 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
- X15 Unvalidated length from an untrusted reader — 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
- X16 Unfloored truncation loop — 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
- X17 Uncapped recursion over a caller-supplied document — 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
- X18 Disposal-pattern 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
- X19 Unrestored process-global state — 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
- 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
- X20 Mistyped argument guard — This check asks whether an argument guard reports an EMPTY value as a NULL one, which needs a language that throws a null-specific argument exception — .NET's ArgumentNullException, the JVM's NullPointerException, Dart's ArgumentError.notNull. This repository contains none of those languages: the ones it is written in have a single exception for a bad argument, so there is no pair of exceptions to confuse and nothing here for it to assess. Not a gap in the analyzer and not a finding about your code.
- X21 Side-effecting pattern guard — Not applicable: this check looks for a pattern guard or `case` label that increments, decrements or assigns while the switch is deciding whether it matches, and in this repository's languages none can. In C a `case` label must be a constant expression, and a switch has no guards, so no label can change state. An Elixir guard admits only guard-safe expressions — the compiler rejects anything else — and a bound value is never mutated in place. Not a gap in the analyzer and not a finding about your code.
- X22 Contradicted release guard — 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
- X23 Unguarded diagnostic materialisation — 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.

- X24 Document value interpolated into markup unescaped — 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
- X25 Inert configuration knob — 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

This is a gap in the analyzer, not a finding about this repository
- X27 Collection changed while being enumerated — 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
- X29 Per-element action decided by a fixed element — 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

This is a gap in the analyzer, not a finding about this repository
- X30 Support guard that admits what it rejects — 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
- X32 Type resolved by simple name across every loaded assembly — This check is about how a .NET program searches the assemblies loaded into its process for a type, and this repository contains no .NET source, so there is nothing here for it to assess. Not a gap in the analyzer and 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
- X6 Hand-rolled structured-format parsing — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
- X7 Silent fallback defaults — 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
