# Verification Report: 2026-04-28-monthly-sonar-review-433

## Status

PASS

## Executive Summary

Verification completed for **Monthly Sonar review workflow and targeted quality remediation #433**.

The implementation matches the proposal, spec, design, and completed tasks for this bounded operational slice:

- the repository provides a canonical documented `make sonar` entry point;
- the local workflow mirrors the hosted Sonar analysis job’s Kotlin, dashboard web, and Rust coverage inputs;
- scanner invocation and prerequisite handling are centralized in `scripts/sonar.sh`;
- the workflow fails closed with clear operator-facing messages when credentials, tools, or prerequisite inputs are missing.

This slice is primarily workflow/operations oriented rather than product-runtime behavior. There are no dedicated automated unit tests specific to the Sonar workflow itself, so verification relied on **real executable probes** of the Makefile and script behavior rather than repository-wide test suites.

- Completed: 10
- Incomplete: 0

Tasks covered:
- Phase 1: Local Sonar workflow foundation
- Phase 2: Coverage and command wiring
- Phase 3: Targeted quality remediation

## Spec Compliance

### Requirement: Canonical Local Sonar Review Workflow

**Status:** PASS

Structural evidence:
- `Makefile`
  - `sonar:` target exists
  - target is documented with help text
  - target is included in `.PHONY`
- `make help` output includes `sonar`

Behavioral evidence:
- `make help` showed the command in the standard command surface
- `make -n sonar` produced one canonical ordered workflow rather than requiring manual reconstruction

Scenario coverage:
- contributor runs one documented local Sonar workflow: PASS
- repository executes local preparation and analysis through one canonical workflow: PASS

### Requirement: Local Sonar Workflow Parity with Hosted Coverage Inputs

**Status:** PASS

Structural evidence:
- `Makefile` `sonar` target runs, in order:
  - `pnpm --dir clients/web install --frozen-lockfile`
  - `bash ./scripts/sonar.sh --validate-only`
  - `./scripts/gradlew.sh test jvmTest :agent-core-kmp:koverXmlReport :composeApp:koverXmlReport`
  - `pnpm --dir clients/web/apps/dashboard test:coverage`
  - `make rust-coverage`
  - `bash ./scripts/sonar.sh`
- `.github/workflows/sonarqube-analysis.yml` hosted workflow runs corresponding coverage steps for:
  - Kotlin Kover XML reports
  - dashboard web LCOV
  - Rust LCOV
- `scripts/sonar.sh` expects and validates these exact artifact classes:
  - `modules/agent-core-kmp/build/reports/kover/report.xml`
  - `clients/composeApp/build/reports/kover/report.xml`
  - `coverage/agent-runtime-coverage.lcov`
  - `clients/web/apps/dashboard/coverage/lcov.info`

Behavioral evidence:
- `make -n sonar` confirmed the local command order mirrors the hosted workflow closely enough for parity
- `scripts/sonar.sh` checks for the expected artifact paths before invoking `sonar-scanner`

Scenario coverage:
- local workflow prepares the same coverage classes of inputs used by hosted analysis: PASS
- hosted Sonar workflow remains the parity reference: PASS

### Requirement: Fail-Closed Local Sonar Prerequisite Handling

**Status:** PASS

Structural evidence:
- `scripts/sonar.sh` explicitly validates:
  - `SONAR_TOKEN`
  - `sonar-scanner` availability
  - `clients/web/node_modules` presence
  - required coverage artifact existence before scan
- `Makefile` validates Rust coverage prerequisites through `rust-coverage-validate`

Behavioral evidence:
- `bash scripts/sonar.sh` failed with clear operator-facing output when `SONAR_TOKEN` was missing
- `SONAR_TOKEN=fake-token bash scripts/sonar.sh --validate-only` failed with clear operator-facing output when hosted-parity web dependencies were missing
- `make -n rust-coverage-validate` showed fail-closed prerequisite checks for `cargo-llvm-cov` and `llvm-tools`

Scenario coverage:
- missing credentials fail closed with clear messages: PASS
- missing tools/prerequisites fail closed with clear messages: PASS
- workflow does not silently continue with weakened analysis inputs: PASS

### Requirement: Bounded Monthly Sonar Maintenance Scope

**Status:** PASS

Evidence:
- proposal/design/tasks stay tightly scoped to:
  - `Makefile`
  - `scripts/sonar.sh`
  - `.github/workflows/sonarqube-analysis.yml`
  - bounded directly related maintenance surfaces
- design explicitly avoids policy drift and repository-wide cleanup
- apply report confirms bounded remediation only in directly affected workflow surfaces

Scenario coverage:
- monthly Sonar review remains a bounded maintenance slice rather than widening into unrelated cleanup: PASS

## Design Conformance

**Status:** PASS

The implementation follows the design decisions:

1. **Add `make sonar` as the canonical local entry point** — followed
2. **Centralize scanner invocation and prerequisite handling in `scripts/sonar.sh`** — followed
3. **Mirror hosted workflow coverage inputs rather than inventing a second source of truth** — followed
4. **Fail fast with operator-facing messages for missing credentials/tools/artifacts** — followed
5. **Keep the slice bounded to directly related quality workflow surfaces** — followed
6. **Avoid broad unrelated cleanup or policy changes** — followed

## Validation Commands Run

### 1. Make help surface

Command:

```bash
make help
```

Result: **PASS**

Observed evidence:
- help output included `sonar`
- command is exposed through the standard repository command surface

### 2. Canonical workflow ordering

Command:

```bash
make -n sonar
```

Result: **PASS**

Observed evidence:
- dry-run output showed the ordered workflow:
  1. bootstrap/check tools
  2. Rust coverage prerequisite validation
  3. web dependency install
  4. `scripts/sonar.sh --validate-only`
  5. Kotlin coverage generation
  6. dashboard coverage generation
  7. Rust coverage generation
  8. final `scripts/sonar.sh` scanner invocation

### 3. Shell syntax validation

Command:

```bash
bash -n scripts/sonar.sh
```

Result: **PASS**

### 4. Missing token fail-closed behavior

Command:

```bash
bash scripts/sonar.sh
```

Result: **PASS**

Observed behavior:
- script exited non-zero
- emitted clear operator-facing message that `SONAR_TOKEN` is required

### 5. Hosted-parity dependency fail-closed behavior

Command:

```bash
SONAR_TOKEN=fake-token bash scripts/sonar.sh --validate-only
```

Result: **PASS**

Observed behavior:
- script exited non-zero
- emitted clear operator-facing message that `clients/web/node_modules` is missing
- instructed the operator to run `pnpm --dir clients/web install --frozen-lockfile` or rerun `make sonar`

### 6. Rust coverage prerequisite validation wiring

Command:

```bash
make -n rust-coverage-validate
```

Result: **PASS**

Observed evidence:
- dry-run output showed fail-closed checks for `cargo-llvm-cov` and `llvm-tools-preview`

## Coverage Assessment

**Status:** ADEQUATE FOR THIS OPERATIONAL SLICE**

This change is primarily a workflow/documented-operations slice rather than a feature with conventional unit tests. Adequate verification for this slice comes from:

- direct inspection of the hosted Sonar workflow as the parity reference;
- direct inspection of `Makefile` and `scripts/sonar.sh` implementation surfaces;
- execution of real workflow probes for help exposure, target ordering, script syntax, and fail-closed prerequisite behavior.

I did **not** run repository-wide `cargo test`, `make web-test-all`, or full `make sonar` because:
- the slice is not owned by a single product code workspace;
- a real Sonar run requires external credentials/tooling and full coverage generation;
- the spec/design focus is on canonical workflow wiring, parity, and fail-closed operator behavior.

For this slice, the executed probes are the authoritative verification evidence.

## Regressions / Critical Issues

No regressions or critical issues were found in the touched operational surfaces.

Notable limitation:
- a full end-to-end Sonar scan was not executed because this environment does not provide a valid `SONAR_TOKEN` and hosted-parity local dependencies/artifacts were intentionally validated through fail-closed probes instead.
- This is acceptable for the slice because the spec explicitly requires fail-closed handling of missing prerequisites, and that behavior was directly verified.

## Verdict

**PASS**

Reason:
- requirements are implemented in the concrete workflow surfaces;
- design decisions were followed;
- tasks are complete;
- executable verification evidence is adequate for this operational slice;
- no regressions or critical issues were identified in the changed surfaces.

## Next Recommended

- This change is ready to be treated as verified.
- If desired, a maintainer with a valid `SONAR_TOKEN` and full local toolchain can optionally run full `make sonar` as an additional confidence check, but it is not required to validate the implemented fail-closed workflow contract.
