Executive summary
Read through the Production lens — the standard calibration. *Green* means good enough to run in production. The score is absolute and comparable across repos.
LeftTwixWand/eShopOnWinUI carries serious gaps (50%). Several issues below can materially affect correctness, security, or the cost of changing it — and propagate to everything that depends on it.
It is strongest in Architecture (92%) — the structure is clean and changes stay contained. Domain Modelling (87%) is solid too.
The area that most needs attention is Security (43%) — exposure to security and compliance incidents is elevated. Maturity (44%) is the next concern — onboarding is slow — key decisions and the architecture aren't written down, so contributors have to reverse-engineer the intent.
Leadership focus, highest impact first: Encrypt sensitive data at rest (ASP.NET Core Data Protection /… (Data Protection); Start an ADR log (docs/adr/) recording significant decisions… (Architecture documentation); Expand the README with getting-started (Documentation (README)).
For scale: Small (~3,074 production lines); rebuilding it from scratch would take roughly ~0.1 person-years (~1 engineer). Approximate, ±~30%.
It builds on a genuinely strong Architecture foundation (92%); the priorities above are the highest-leverage way to bring the rest up to that level.
Raise Security 43 → 70 (the Healthy floor) ⇒ headline 50 → ~55.
Rebuild cost & value ~ Modeled — €1,200–€6,000

Roadmap
Immediately encrypt sensitive data at rest and manage keys in a vault to secure the system. Simultaneously, begin logging significant architectural decisions and expand the README to provide a clear, accurate overview of the project. Finally, resolve the remaining orphaned files and update the documentation to ensure it accurately reflects the current state of the codebase.

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. 54 of 57 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 0.6 — 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 — 57 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, 19 of 26 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.

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 (jscpd) — it finds copy-paste, not semantic duplication expressed differently. Committed machine-written code (EF migration scaffolds, *.Designer.cs, model snapshots) is EXCLUDED — its repetition is the tool's, not the team's — so the score reflects hand-written duplication only; the generated footprint is reported separately under Solution Shape.
- D5 Coupling: Coupling is measured between projects/assemblies — runtime coupling through DI, reflection, messaging or shared databases is invisible to a static reference graph.
- D6 Cohesion (LCOM4): LCOM4 cohesion is syntactic — it infers connectivity from which methods touch which fields/methods by name, not from real runtime behaviour or intent.
- D8 Code Coverage: Coverage is measured by building and running the suite (`dotnet test --collect`) inside Watchdog's isolated image — the target repo is never modified, and nothing on your systems runs. So coverage exists only when the suite builds and runs within the inline time budget; one that needs external services, can't build, or exceeds the budget yields no coverage (D8 then degrades to not-measured, not a low score). Line coverage also says nothing about assertion quality.
- D9 Test Distribution: The test-pyramid shape is inferred from project/folder naming and references, with a single test host bucketed per-file by its path tier and content signals — a suite that names tiers unconventionally and gives no per-file signal can still be mis-bucketed.
- D10 Test Quality: Assertion density is structural — it cannot tell a meaningful behavioural assertion from a trivial one, only that an assertion is present.
- 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.
- D16 Bus Factor: Bus-factor is a time-decayed model of commit attribution (who has recently, repeatedly worked a file), not comprehension — pairing, review and reading-without-committing spread knowledge it can't see; bot commits and shared accounts still distort it.
- 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 (EF migrations, designer files, snapshots) is excluded — it is never the team's dead code to delete.
- D18 Solution Shape: Build integrity reflects whether the solution compiled in this environment — a build that needs a private feed, a specific SDK, or a generated file absent from the repo can read as broken when it is merely unreproducible here.
- D19 Documentation Quality: Documentation quality is judged by an LLM over a bounded sample of docs — it reads what is written, not whether the docs match the running system, and it is advisory, not a measurement.
- 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.
- D24 Comment Value: Comment value (WHY vs WHAT) is an LLM judgement over a bounded sample — it is advisory and cannot weigh a comment against the precise code change it was written to explain.
- D26 Project Cohesion: Project focus is sized from members/namespaces per project — a project that is broad by deliberate design reads the same as one that has sprawled.
- D28 Secrets (history): Secret-history scanning sweeps the git log for known patterns — a secret that predates the available history, or never matched a signature, is not found (clean means "nothing matched in the history we can see").
- D29 Static Analysis (SAST): SAST findings are pattern-based (semgrep) — it finds classes of bug it has rules for; logic flaws, auth/authorization gaps and issues needing runtime context are out of reach (and clean means "no rule matched").
- D34 Knowledge Freshness: Freshness is decayed commit RECENCY, not comprehension — code read often but rarely committed reads as orphaned, and stable code that genuinely needs no changes is penalised the same as forgotten code; bot/squash commits distort it like the bus factor.
- D35 Change Coupling: Change coupling is co-change in COMMITS — files split across separate commits, or coupled only through a shared config/build step, read as uncoupled, and a sweeping commit (rename/format) is excluded so it doesn't couple everything. It shows that files change together, not WHY: a high coupling can be a healthy cohesive pair as readily as a hidden leak.
- AX10 Code composition: Role is inferred from namespace/folder convention, not semantics — a domain concept living in a folder named "Services" reads as application, and the split is lines-of-code, not business value. The business-logic-share score is a SOFT, FLOORED signal: it contributes to the Architecture lens but is floored at the Critical gate, so an infrastructure-heavy design (a gateway, an ETL, a driver) is legitimately low without being nuked to zero.
- 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.
- DM4 Rich vs anemic model: Behaviour is detected as state mutation inside a method body — a method that enforces an invariant by validating-and-throwing without mutating reads as a query, and mutation delegated through an interface the scan can't resolve isn't credited; entities with zero public properties still drop out of the population. It detects that state changes, not whether the rule is correct.
- DM6 Domain ↔ infrastructure boundary: Infrastructure reached through a hand-rolled wrapper, a domain-named facade, reflection, or a string-keyed service locator resolves to a non-infra type and isn't seen; the body scan is symbol resolution over syntax, not full dataflow. A clean result means "no resolved infra reference in a domain body", not a proof of purity.
- 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".

D19 · Documentation Quality
The single README is a thin one-file documentation that describes the project as an inventory sample rebranded to WinUI 3 with DDD/Clean Architecture and lists a skeletal 'Readme structure' outline (1-5) plus two inline images. It does not describe what the app actually does, how it is built, or where to find architecture details such as layers, repositories, services, or domain models. The architecture section points to an obsolete drawio diagram and no XML docs; the technologies list is empty.
What to do

AX7 · Slice cohesion
AX8 · Test isolation
AX9 · CQS / query purity
C1 · Data Protection
- No data-protection or encryption usage (ASP.NET Data Protection, AES, column encryption, PBKDF2) was found — sensitive data at rest may be unprotected. If TDE/KMS/vault is delegated to infrastructure, ignore.
What to do
- Encrypt sensitive data at rest (ASP.NET Core Data Protection / column encryption) and manage keys in a vault. Skip if delegated to infra (Postgres TDE, KMS, etc.).
- Enforce HTTPS (UseHttpsRedirection / RequireHttpsMetadata) so data in transit is always encrypted.
DM1 · Aggregate boundaries
DM2 · Strongly-typed ids
DM4 · Rich vs anemic model
- `Customer` is an aggregate/entity with 8 data propert(ies) but no state-changing behaviour (only data and queries) — the business logic lives in a service. — Customer.cs:7
- `Product` is an aggregate/entity with 5 data propert(ies) but no state-changing behaviour (only data and queries) — the business logic lives in a service. — Product.cs:6
- `Shipment` is an aggregate/entity with 9 data propert(ies) but no state-changing behaviour (only data and queries) — the business logic lives in a service. — Shipment.cs:7
What to do
- Move business rules onto the aggregates/entities they govern so invariants are enforced at the source, not in anemic services.
DM5 · Encapsulated state
- `Customer` exposes public setter(s) (Picture). — Customer.cs:7
What to do
- Make entity setters private/init-only; change state only through methods that enforce the invariants (Marten/EF can bind via constructor or private setters).
DM6 · Domain ↔ infrastructure boundary
DM8 · Value-object opportunities
GD1 · Unfinished & placeholder code
- A shipped member still throws NotImplementedException — generated scaffolding that was never completed. Implement it or remove the dead surface. (×7) — ProductsRepository.cs:31, WarehousesRepository.cs:12, WarehousesRepository.cs:17, …
What to do
- Finish or delete NotImplementedException stubs and replace placeholder literals before shipping.
IC1 · Incompleteness & stubs
- `Handle` is declared `async` but never awaits anything, so it runs synchronously while pretending to be asynchronous. Drop `async` or do the real async work. — GetProducts.cs:11
- `Loaded` is declared `async` but never awaits anything, so it runs synchronously while pretending to be asynchronous. Drop `async` or do the real async work. — ProductsViewModel.cs:54
- `Apply` looks like it should compute a result but its body just returns a constant — a placeholder return that was never filled in. — ActualProductQuantityProjection.cs:35
- `DeleteManyByIdAsync` is a shipped member whose whole body throws NotImplementedException — scaffolding that was never completed. Implement it or remove the dead surface. — ProductsRepository.cs:29
- `GetByIdAsync` is a shipped member whose whole body throws NotImplementedException — scaffolding that was never completed. Implement it or remove the dead surface. — WarehousesRepository.cs:10
- `GetFromSnapshotAsync` is a shipped member whose whole body throws NotImplementedException — scaffolding that was never completed. Implement it or remove the dead surface. — WarehousesRepository.cs:15
- `GetManyByIdAsync` is a shipped member whose whole body throws NotImplementedException — scaffolding that was never completed. Implement it or remove the dead surface. — WarehousesRepository.cs:20
- `ConvertBack` is a shipped member whose whole body throws NotImplementedException — scaffolding that was never completed. Implement it or remove the dead surface. (×3) — ImageConverter.cs:22, SelectionModeToBooleanConverter.cs:20, ValueConverterGroup.cs:12
- A line of code has been commented out rather than removed — dead weight that rots and confuses. Delete it (version control remembers). (×4) — ThemeSelectorService.cs:50, ThemeSelectorService.cs:59, WarehouseEntityTypeConfiguration.cs:34, …
What to do
- Finish or delete the unfinished stubs (NotImplementedException / empty / constant-returning bodies) — they are dead surface that looks live.
- Clear the softer debt: remove commented-out code and dead branches, re-enable or delete skipped tests, and replace blanket warning suppressions with targeted ones.
M1 · Documentation (README)
- The root README is 84 words — likely missing build/run/architecture context.
What to do
- Expand the README with getting-started, architecture overview and a project map.
- Add a build/run (quick start) section to the root README — the first thing a newcomer needs.
- Add a 'Testing' section to the root README — how to run the test suite.
- Add a README to the 5 of 5 project(s) that lack one — worth up to 2 pts.
M2 · Architecture documentation
- No Architecture Decision Records found — decisions aren't captured for future maintainers.
- No C4/PlantUML/Mermaid diagram or architecture.md — the high-level shape isn't documented.
What to do
- Start an ADR log (docs/adr/) recording significant decisions and their rationale.
- Add a C4 context/container diagram (Structurizr, PlantUML or Mermaid) or an architecture.md overview.
M3 · Folder & project structure
M4 · Documentation accuracy
- Architecture section is stale and obsolete
What to do
- Reconcile the README with reality: Architecture section is stale and obsolete.
P1 · CI/CD gates
P11 · BDD / executable specs
P2 · Observability
- Only 2/5 service-like projects use logging (pure contract/DTO projects are excluded — they have nothing to log).
What to do
- Extend structured logging to the remaining service-like projects so the whole executable surface is diagnosable in production.
- Consider OpenTelemetry tracing/metrics and a health-check endpoint for operability.
P3 · Security & performance tooling
- No static application security testing (CodeQL / security analyzers / codehealth) detected.
What to do
- Add a SAST step (e.g. CodeQL) or a security analyzer package.
- Add gitleaks/trufflehog in CI to block PRs that introduce committed secrets.
P4 · Deployment & Rollback
- Deployment automation exists but no readiness/liveness probes, rolling-update strategy, lifecycle hooks or migration job were evidenced — a bad release is harder to detect and reverse.
What to do
- Add readiness/liveness probes and a rolling-update (or blue/green) strategy so a bad release is caught and rolled back automatically.
- Add an approval/environment gate (required reviewers / protection rules) before production promotion.
P8 · Schema migrations
- EF Core is used but neither migrations nor EnsureCreated were detected — confirm how the production schema is created and evolved.
What to do
- Adopt EF migrations (dotnet ef migrations add + Migrate() on startup) as the explicit, versioned schema strategy — no migration mechanism was detected.
X1 · Async correctness
- `async void` can't be awaited and its exceptions crash the process instead of propagating. Return `Task` unless this is a top-level event handler. — App.xaml.cs:36
What to do
- async void method: OnLaunched
X2 · Cancellation propagation
- Only 15/21 async methods accept a CancellationToken, so requests can't be cancelled cleanly under load or on client disconnect. In Blazor Server circuits and other short-write hosts, omitting it can be an accepted convention — judge against your hosting model.
- No CancellationToken parameter — work can't be cancelled cleanly on disconnect/shutdown. (×6) — ActivationHandler.cs:20, ProductViewModel.cs:13, ActivationService.cs:11, …
What to do
- Thread a CancellationToken through async methods so work stops promptly on cancellation.
X3 · Exception handling
X4 · Structured logging
X5 · Nullable reference types
- 2/5 projects enable <Nullable>enable</Nullable>. NRTs catch a whole class of null-deref bugs at compile time.
- ~0.7 `!` suppressions per 1k syntax nodes — each one tells the compiler to trust you about null, suppressing the very safety NRTs provide.
What to do
- Enable <Nullable>enable</Nullable> across all projects and resolve warnings rather than suppressing with `!`.

- AC7 A11y enforcement — No web markup found — accessibility is not applicable to this repository.
- AX1 Captive dependencies — no DI registrations detected
- AX2 Stateful singletons — no singleton implementations detected
- AXB2 Runtime readiness — no data
- C2 Access Controls — No access-control surface detected in the analyzed source — no web/app surface to authorize (no HTTP API or web-UI project) and no authorization code at all (no [Authorize]/policies, no imperative guard methods). Access control is therefore N/A here — this is a library/CLI, which is authorized by its CALLER, not by itself. If this codebase grows request handlers, the dimension reactivates and a default-deny posture is expected then.
- C3 Audit Trail — Repo shows no audit-logging mechanism (IAuditable, an immutable audit log, an EF SaveChanges interceptor) for sensitive changes — absence of evidence is not evidence of a working control. Record an audit trail in code (or document where it lives) so this dimension can be scored.
- C4 Data Retention — Repo shows no data-retention / TTL / cleanup mechanism for personal data — absence of evidence is not evidence of a working control. Define retention periods and a purge/cleanup job (or TTL) in code, or document where retention is enforced, so this dimension can be scored.
- C5 Data-Subject Rights — Repo shows no corroborated data-subject-rights mechanism (erasure / export-portability / consent) tied to a subject id or GDPR vocabulary — absence of evidence is not evidence of a working control. Implement erasure, data export/portability and consent tracking over the subject's records.
- D11 Test Reliability — Test reliability not included
- D22 Internal API Consistency — No exposed public API
- D23 Boundary Type-Coupling — At only 3074 LoC the codebase is small despite 5 projects and no boundaries declared, so explicit bounded-context boundaries are not needed.
- D25 ADR Conformance — no ADRs to check
- D27 Navigability — symbol resolution incomplete — navigability not assessed
- D30 Dependency Vulnerabilities — the solution did not restore on the analyzer's .NET SDK (an SDK/target-framework/restore mismatch, common for an older codebase), so there was no restored dependency graph to scan for NuGet CVEs — excluded rather than scored; re-run on an SDK that can restore this solution
- D31 IaC & Container Security — No Infrastructure-as-Code or container manifests found (Dockerfile, Terraform, Kubernetes/Helm, CloudFormation); nothing to scan.
- D32 Data Compliance (PII/GDPR) — No PII/GDPR-handling patterns detected (p/gdpr ruleset) — no data-compliance surface to assess.
- D33 JS/npm Dependency Vulnerabilities — No JS/npm manifest or lockfile found outside bin/obj (package.json, package-lock.json, yarn.lock, pnpm-lock.yaml, bun.lockb); no JS dependencies to scan.
- D36 Supply-chain Provenance & Signing — The CI pipeline builds and tests but publishes no released artifact — no package publish, container push, GitHub release or deployment step. Supply-chain provenance, signing and SBOM attest RELEASED artifacts, so there is nothing to attest here. Add them to the release pipeline when this repo starts shipping artifacts (a NuGet package, a container image, a GitHub release).
- D37 Vulnerability-disclosure Policy — No vulnerability-disclosure policy file found (SECURITY.md, .github/SECURITY.md, docs/SECURITY.md, .well-known/security.txt). A coordinated-disclosure policy may live off-repo, so this is not evidenced rather than failed.
- D38 OSV Dependency Vulnerabilities — No JS/npm lockfile found outside bin/obj (package-lock.json, yarn.lock, pnpm-lock.yaml, bun.lockb); nothing for OSV to scan.
- D39 IL Efficiency — The target did not build, so no IL was available to measure.
- D7 Architectural Integrity — no checkable ADRs and no dependency cycles — architectural integrity not assessed
- DM3 Integration-event coupling — no integration events detected — coupling check not applicable
- DM7 Repository granularity — no repository abstraction detected (e.g. uses a document session)
- ED1 Event-Driven — applicable but skipped (2/3 markers — below the conservative bar): a message-bus package; 9 CQRS handler(s)
- ED5 Idempotency — no mutating command handlers or message consumers detected — idempotency check not applicable
- ES1 Event Sourcing — not run — 0/3 markers found
- P12 CI test-gate honesty — no data
- P5 DR & Backup — not evidenced — repo shows no backup/RTO/RPO controls; absence of evidence is not evidence of a working control
- P6 Release Hygiene — not evidenced — no changelog, version stamp or semver release tag in the repo
- P7 Outbound HTTP resilience — not applicable — this isn't a service/API/worker
- P9 Domain vs controller coverage — no coverage report found on disk — run tests with `--collect:"XPlat Code Coverage"` (or in CI) to enable this cross-layer check
- PF1 Benchmark discipline — Performance is assessed only for perf-relevant repos — a packaged library, one that ships benchmarks, or one already using allocation-aware APIs. This repo isn't one, so the Performance lens is not applicable and is excluded from the score.
- PF2 Allocation hygiene — Performance is assessed only for perf-relevant repos — a packaged library, one that ships benchmarks, or one already using allocation-aware APIs. This repo isn't one, so the Performance lens is not applicable and is excluded from the score.
- PF3 Async & latency hygiene — Performance is assessed only for perf-relevant repos — a packaged library, one that ships benchmarks, or one already using allocation-aware APIs. This repo isn't one, so the Performance lens is not applicable and is excluded from the score.
- S1 Web-Security Posture — No web surface detected in the analyzed source — no HTTP API or web-UI project (no controllers/minimal-API endpoints, no Razor/Blazor views) and no web middleware (HTTPS redirection, HSTS, security headers, cookies). Transport security, security headers, secure cookies, CSRF/input-validation and middleware-order controls are therefore N/A here — this is a library/CLI/worker, not a web app. Crypto hygiene was still checked and found nothing to flag. If this codebase becomes web-facing, the dimension reactivates automatically.
- SC1 Supply-chain hygiene — no data
- X6 Hand-rolled structured-format parsing — no data
- X7 Silent fallback defaults — no data
