Executive summary
The system holds an overall health score of 55%, indicating an adequate but fragile state that requires immediate attention to prevent operational friction. While the code itself is clean and the architecture is sound, the organization lacks the institutional knowledge to sustain it, creating a significant risk for future delivery speed and reliability.
This is a small asset, comprising roughly 7,000 lines of production code, with a rebuild cost of approximately €9,000. Because the value tied up here is modest, the primary risk is not financial loss from a total collapse, but rather the slow erosion of team velocity as new engineers struggle to understand the system. The low maturity score suggests that critical context is missing, meaning changes are slower and more error-prone than they should be for a system of this size.
The most pressing issue is knowledge decay. With a maturity score of 39%, the team is operating with incomplete mental models. This leads to longer onboarding times, accidental regressions, and an inability to confidently modify legacy components. The lack of documented decisions means that every change requires re-litigating past choices, wasting engineering time and increasing the likelihood of defects. This is a direct tax on delivery speed.
Conversely, the code quality and architectural integrity are strong, with scores of 89% and 90% respectively. The system is secure and well-structured, meaning the foundation is solid. However, this strength is undermined by outdated documentation, such as the README claiming features that do not exist. This mismatch creates confusion and erodes trust in the available resources, further slowing down development cycles.
To maximize leverage, focus first on capturing key decisions. Implementing a simple, consistent process for recording architectural decisions will immediately reduce ambiguity and accelerate onboarding. This low-effort action addresses the root cause of the maturity gap. Once this foundation is laid, the team can confidently address the remaining documentation inconsistencies, ensuring the system remains maintainable and reliable for the long term.
Raise Maturity 39 → 70 (the Healthy floor) ⇒ headline 55 → ~65.

Roadmap
Begin by documenting key architectural decisions in a structured format and reconciling the README to accurately reflect the project's current state and capabilities. Simultaneously, address the eight orphaned knowledge items, focusing first on the core LeoFS worker and storage modules, while resolving the single leaked secret in the server key file. Finally, ensure all major design choices are formally recorded through Architecture Decision Records to maintain long-term knowledge freshness.
| Do this | Helps | Effort | Dimension |
|---|---|---|---|
| Resolve the 8 Orphaned knowledge finding(s) in Knowledge Freshness — start with leo_compact_fsm_worker.erl, leo_object_storage_haystack.erl, leo_compact_fsm_controller.erl. | +13.3 pts | Low | Knowledge Freshness |
| Resolve the 1 No ADRs found finding(s) in ADR Quality. | +10.7 pts | Low | ADR Quality |
| Resolve the 1 Leaked secret finding(s) in REDACTED Scanning — start with REDACTED. | +9.7 pts | Low | REDACTED Scanning |
| 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). | +14.6 pts | Medium | Architecture documentation |
| Reconcile the README with reality: README claims LeoFS is a separate project but the evidence shows no leo_storage or leofs projects; README advertises Docker containerisation, but no Dockerfile/compose file exists. | +14.6 pts | Medium | Documentation accuracy |
| Keep a changelog (e.g. Keep-a-Changelog) recording what shipped in each release. | +9.7 pts | Medium | Release Hygiene |
| Run the test suite in CI via an explicit runner step for your stack, and gate merges on it. | +7.6 pts | Medium | CI/CD gates |
| Resolve the 1 Documentation finding(s) in Documentation Quality — start with README.md. | +3.1 pts | Low | Documentation Quality |

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. 30 of 34 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 0.8 — 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 — 34 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, 54 of 66 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
- 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 (.erl) 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 (`rebar3 do eunit --cover, cover` (or covertool for Cobertura XML)) 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 (`rebar3 do eunit --cover, cover` (or covertool for Cobertura XML)) 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 (.erl) and this repository declares a rebar3 project (repository root, 13 test files), but it was not re-run: the analyzer environment could not run it. Not scored — this is a gap in the analyzer's language coverage, not a finding about this repository.
- 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. Not scored — 3 rebar3 declaration(s) across 1 `rebar.config` and 5 package(s) pinned by a committed `rebar.lock` were read for PINNING discipline (0 defect(s) reported), but the outdated/retired signal needs hex.pm, and no declaration here is resolved to a release by a committed rebar.lock, so this dimension's own question is only partly answered. NOT a finding that these dependencies are current or healthy.
- 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 package manifest is not parsed for licence data yet. A gap in the analyzer's language coverage, NOT a finding that the repository's licenses are compliant (a rebar.config / erlang.mk DEPS (Hex)), which this pass does not parse yet — so this dimension asserts nothing about this repository's licensing in either direction.
- 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 (4 contributor(s) across 886 commit(s) sampled, automation and bot accounts excluded). One of them holds 89% of the history; the other 3 hold 3.7% 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 (src/leo_object_storage.app.src), 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.
- 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.

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.
- 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 and JavaScript/TypeScript source only, and no C# or JavaScript/TypeScript was found, and this repository's Erlang is not read yet, so it had nothing of this repository's product to read.

- P10 Library API & versioning — 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 NuGet packaging and C# public API, and npm, PyPI, crates.io, Maven/Gradle, Go module, RubyGems, Composer, SwiftPM, pub.dev and Hex package manifests only, and no .NET project and no package manifest of those ecosystems 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.
- 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.
- PF1 Benchmark discipline — 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.

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.
- D13 REDACTED Scanning: REDACTED detection is signature- and entropy-based on the current tree — a secret that does not match a known pattern, or one already rotated, will not be flagged (a clean scan is "nothing matched", not "no secrets exist").
- 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.
- D20 ADR Quality: ADR quality is an LLM read of the decision records present — it cannot know about decisions made and never recorded, and its verdict is sampled and advisory.
- 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.
- AX9 CQS / query purity: Handlers are found by interface/name convention — a query handler using neither is not seen. Mutation is a resolved write/publish invocation (SaveChanges/repository/bus), so a write hidden behind a hand-rolled wrapper, reflection, or a string-keyed service locator resolves to a non-persistence type and isn't flagged; it detects that a query writes state, not whether the write is a legitimate read-side cache update. Clean means "no resolved write/publish in a query body", not a proof of CQS purity.
- 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
D1 · Cyclomatic Complexity
3 function(s) exceeded the cyclomatic complexity threshold of 15; the worst was leo_object_storage_server.handle_call at 66. A further 4 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 leo_compact_fsm_worker.running at 29 — 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: src/leo_compact_fsm_controller.erl (leo_compact_fsm_controller.running at 23). 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.
What to do
- Bring the 1 body over 30 down to 30 or less in Cyclomatic Complexity — start with leo_object_storage_server.handle_call (cyclomatic 66). — Refactoring it lifts Cyclomatic Complexity from 8.2 to about 9.0/10.
- Enforce Cyclomatic Complexity in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.
D2 · Cognitive Complexity
3 function(s) exceeded the cognitive complexity threshold of 15; the worst was leo_compact_fsm_worker.execute_1 at 22.
What to do
- Bring the 3 bodies over 15 down to 15 or less in Cognitive Complexity — start with leo_compact_fsm_worker.execute_1 (cognitive 22), leo_object_storage_api.fetch_by_key (cognitive 19), leo_object_storage_haystack.get_fun_2 (cognitive 19). — This score is capped by its worst body, so a finding fixed alone moves it by almost nothing — the next one down takes its place. Refactoring these 3 together lifts Cognitive Complexity from 9.4 to about 10.0/10, projected with the scoring formula itself and assuming each lands exactly at 15.
- Enforce Cognitive Complexity in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.
D3 · God Classes
6 over-large unit(s) detected — types, modules or files that carry too much.
What to do
- Resolve the 6 FileTooLong finding(s) in God Classes — start with leo_compact_fsm_worker.erl, leo_object_storage_haystack.erl, leo_compact_fsm_controller.erl. — One of this dimension's main actionable groups (6 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
29 duplicated block group(s) detected. A further 2 rows report members as variants of one another; they aggregate block groups already counted above and are not themselves counted.
What to do
- Resolve the 3 Duplicated block (11 lines × 2) finding(s) in Code Duplication — start with leo_object_storage_haystack.erl (3). — One of this dimension's main actionable groups (3 warning-level).
- Resolve the 2 Duplicated block (17 lines × 2) finding(s) in Code Duplication — start with leo_object_storage_transformer.erl (2). — One of this dimension's main actionable groups (2 warning-level).
- Resolve the 2 Duplicated block (15 lines × 4) finding(s) in Code Duplication — start with leo_compact_fsm_controller.erl, leo_object_storage_transformer.erl. — One of this dimension's main actionable groups (2 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 3 classes have LCOM4 above 3.
D13 · REDACTED Scanning
1 secret(s) detected.
What to do
- Resolve the 1 Leaked secret finding(s) in REDACTED Scanning — start with REDACTED. — One of this dimension's main actionable groups (1 issue-level).
- Enforce REDACTED Scanning in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.
D15 · Churn × Complexity Hotspots
No churn × complexity hotspots in the window.
D17 · Explicit Debt
0 deducted task-comment markers across 7059 LoC (0.0/KLoC) → score 10.0. 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.
D19 · Documentation Quality
The repository's root README is clear and complete for a project: it states the Erlang/OTP version required, adds an overview of what the library does (log-structured Haystack/BLOB storage with AVS format), lists key features, gives installation/deps/build/test commands, and documents architecture in module structure and storage-format detail. The body is clipped mid-architecture section, so any unshown sections are not flagged as missing.
What to do
- Resolve the 1 Documentation finding(s) in Documentation Quality — start with README.md. — One of this dimension's main actionable groups (1 recommendation-level).
D20 · ADR Quality
No architecture decision records were found.
What to do
- Resolve the 1 No ADRs found finding(s) in ADR Quality. — One of this dimension's main actionable groups (1 recommendation-level).
D21 · Naming Consistency
0 naming inconsistencies across 0 sampled symbols.
D26 · Project Cohesion
1 of 1 build units (rebar3) flagged as possibly oversized/incoherent.
What to do
- Resolve the 1 Projects may be oversized for their cohesion finding(s) in Project Cohesion. — One of this dimension's main actionable groups (1 recommendation-level).
D28 · Secrets (history)
1 finding(s): 0 critical, 1 high, 0 medium, 0 low. Remediation for historically-committed secrets is credential rotation — they remain in history regardless of later deletion.
What to do
- Resolve the 1 REDACTED finding(s) in Secrets (history) — start with REDACTED. — One of this dimension's main actionable groups (1 issue-level).
- Resolve the 1 Rotate the exposed credentials finding(s) in Secrets (history). — One of this dimension's main actionable groups (1 recommendation-level).
D29 · Static Analysis (SAST)
semgrep found no security issues.
D30 · Dependency Vulnerabilities
No known-vulnerable dependencies in any ecosystem this repository declares.
D34 · Knowledge Freshness
11 of 11 significant source file(s) are orphaned — their living knowledge has decayed to nothing, so no one currently understands them. The largest is src/leo_compact_fsm_worker.erl. Counted over 11 of the 12 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 8 Orphaned knowledge finding(s) in Knowledge Freshness — start with leo_compact_fsm_worker.erl, leo_object_storage_haystack.erl, leo_compact_fsm_controller.erl. — One of this dimension's main actionable groups (8 issue-level).
- Resolve the 1 Further orphaned files (smaller) finding(s) in Knowledge Freshness. — One of this dimension's main actionable groups (1 recommendation-level).
D35 · Change Coupling
No strong hidden change-coupling between production files.
D36 · Supply-chain Provenance & Signing
0/3 supply-chain integrity signals present (provenance, signing, SBOM).
What to do
- Resolve the 1 REDACTED finding(s) in Supply-chain Provenance & Signing. — One of this dimension's main actionable groups (1 recommendation-level).
- Resolve the 1 REDACTED finding(s) in Supply-chain Provenance & Signing. — One of this dimension's main actionable groups (1 recommendation-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
AX9 · CQS / query purity
ES1 · Fold determinism
ES2 · Immutable events
M1 · Documentation (README)
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 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).
M3 · Folder & project structure
M4 · Documentation accuracy
- README claims LeoFS is a separate project but the evidence shows no leo_storage or leofs projects — searched for: `leo_storage`, `leofs`. Each was matched case- and separator-insensitively against file and directory NAMES anywhere in the tree, and against the CONTENTS of manifest files (package.json, *.csproj, *.props, *.slnx, *.yml, Dockerfile); the README's own prose never counts, so a claim is never refuted by merely being made. Nothing outside that search was read — a footprint living only in a submodule, in a file type not listed here, or under a name none of those terms matches is not seen, and this row is then wrong.
- README advertises Docker containerisation, but no Dockerfile/compose file exists — searched for: `dockerfile`, `docker-compose`, `compose.yaml`, `compose.yml`. Each was matched case- and separator-insensitively against file and directory NAMES anywhere in the tree, and against the CONTENTS of manifest files (package.json, *.csproj, *.props, *.slnx, *.yml, Dockerfile); the README's own prose never counts, so a claim is never refuted by merely being made. Nothing outside that search was read — a footprint living only in a submodule, in a file type not listed here, or under a name none of those terms matches is not seen, and this row is then wrong.
What to do
- Reconcile the README with reality: README claims LeoFS is a separate project but the evidence shows no leo_storage or leofs projects; README advertises Docker containerisation, but no Dockerfile/compose file exists.
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 for your stack, and gate merges on it.
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.
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.

Not evidenced — 5 control(s) we could not find positive evidence for
- C3 Audit Trail — Not assessed: these audit 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 audit controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
- C4 Data Retention — Not assessed: these retention controls are read from 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 retention controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
- C5 Data-Subject Rights — Not assessed: these data-subject rights controls are read from 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 data-subject rights controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
- P4 Deployment & Rollback — not evidenced — no deploy/rollback/approval signal in the repo; absence of evidence is not evidence of a manual release
- P5 DR & Backup — not evidenced — repo shows no backup/RTO/RPO controls; absence of evidence is not evidence of a working control
Not included — 82 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: Erlang 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
- 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.
- C1 Data Protection — Not assessed: these personal data 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 personal data controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
- C2 Access Controls — Not assessed: these authorization controls are read from 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 authorization controls: it may implement them entirely in its own ecosystem. This is a gap in the analyzer's language coverage, not a finding about this repository.
- D10 Test Quality — ~1957 lines of test source are present (.erl) 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 — the .erl suite was found but not re-run
- D12 Dependency Hygiene — Not scored — 3 rebar3 declaration(s) across 1 `rebar.config` and 5 package(s) pinned by a committed `rebar.lock` were read for PINNING discipline (0 defect(s) reported), but the outdated/retired signal needs hex.pm, and no declaration here is resolved to a release by a committed rebar.lock, so this dimension's own question is only partly answered. NOT a finding that these dependencies are current or healthy.
- D14 License Compliance — Package manifest not parsed for licence data — analyzer language-coverage gap
- 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.
- 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 — symbol resolution incomplete — navigability not assessed
- 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 (.erl) 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 (175 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
- GD1 Unfinished & placeholder code — no source files were read — this check reads C# and JavaScript/TypeScript, and neither 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
- P10 Library API & versioning — 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 Erlang source (1 module(s), 12 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 Erlang 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 (`rebar3 do eunit --cover, cover` (or covertool for Cobertura XML)) 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 — Benchmark discipline was not assessed: this repository is written in Erlang, whose benchmark frameworks this check does not search yet. That is a gap in the analyzer's language reach, not a finding about your code.
- PF2 Allocation hygiene — Not applicable: Erlang 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: Erlang has no async/await function colour, 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 — 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. An Erlang guard admits only comparisons, arithmetic and guard BIFs — the compiler rejects anything with an effect — and a variable is bound exactly once. Not a gap in the analyzer and not a finding about your code.
- X22 Contradicted release guard — Not applicable: this check looks for a method whose returned value contradicts the flag its `finally` reads to decide whether to give back a lock it took, and in this repository's languages the body cannot set a flag that its cleanup reads. Erlang will not compile it: a variable bound inside `try` is "unsafe" in its `after` clause, so the body cannot record a handoff where the cleanup can read it. Not a gap in the analyzer and not a finding about your code.
- 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. This is a gap in the analyzer, not a finding about this repository
- 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
- X26 Unsynchronised callback handoff — Not applicable: this check looks for a collection written by a callback on one thread while the body waiting on it touches it on another, and in this repository's languages no collection is reachable from two threads at once. Erlang processes share no heap: a value sent to another process arrives as a copy, so no collection is reachable from two processes at once. Not a gap in the analyzer and not a finding about your code.
- 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
- 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 — 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
- X31 Test-only surface in a production module — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.
- 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 applicable: this check asks whether the null-typed discipline a language offers is switched on, and how much of that the assertion operator takes back, and in this repository's languages there is no such switch and no such operator. Erlang has no null: every variable is bound, absence is a value you pattern-match (`undefined`, `nil`, the error tuples), and there is no static type checker whose null warning could be turned on or off. Not a gap in the analyzer and not a finding about your code.
- X6 Hand-rolled structured-format parsing — 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
- 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
- X9 Subsumed condition operand — Advisory — this card reports evidence and never carries a score, so there is nothing missing here.

| 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 | — |
