Closes #96

Summary

Adds a public health check endpoint at GET /api/health that returns JSON with status and openRegisterAvailable fields. Returns HTTP 200 when OpenRegister is available (status: "ok") and HTTP 503 when unavailable (status: "degraded"). The endpoint requires no authentication, making it suitable for load balancers and monitoring systems. The version field is intentionally omitted to prevent unauthenticated version fingerprinting (SEC-001 / CWE-200).

Spec Reference

Changes

  • lib/Controller/HealthController.php — New controller with public index() action returning health status JSON; uses @PublicPage and @NoCSRFRequired annotations for unauthenticated access; version omitted per SEC-001/CWE-200
  • openapi.yaml — New OAS 3.0 document for the Planix API, documenting the GET /api/health endpoint with 200 and 503 response schemas
  • openspec/changes/status-api/tasks.md — Updated acceptance criterion to reflect that version is intentionally omitted

Test Coverage

  • tests/unit/Controller/HealthControllerTest.php — 3 test methods: healthy response (200 + "ok"), degraded response (503 + "degraded"), and response field completeness verification (including assertion that version is not present)

Hydra Builder — Fix iteration 1

Fixed findings:

  • [CRITICAL] PHPUnit failure on NC stable33 / PHP 8.4: IAppConfig::setValueString() was introduced with a bool return type in Nextcloud 31+. Two test callbacks in SettingsServiceTest declared void return type and returned nothing, causing TypeError: MockObject::setValueString(): Return value must be of type bool, null returned at runtime. Fixed by changing the closure signatures to : bool and adding return true; in both testSetAdminSettingsIgnoresUnknownKeys and testSetAdminSettingsStoresAllowProjectCreation.

Remaining SUGGESTIONs (not addressed — informational only):

  • None

Note: /browser-report.json was an empty mount. Failure root cause was identified directly from the CI run log (workflow run 24042392578). All 15 PHPUnit tests now pass with the fix in place.

Hydra Builder — Fix-Browser iteration

The `/browser-report.json` mount was empty — no Playwright browser test results were present to analyse.

Investigation of the CI history revealed the root cause of all test failures had already been addressed in Fix iteration 1:

  • The PHPUnit failure (TypeError: MockObject::setValueString(): Return value must be of type bool, null returned) was fixed by updating the willReturnCallback closures in SettingsServiceTest to declare : bool return types and return true.
  • No browser/E2E tests are currently enabled in the quality workflow (enable-playwright: false), so there were no UI-layer failures to address.

CI result after the iteration-1 fix (runs 24043097430 and 24043095706):
All 6 PHPUnit matrix jobs (PHP 8.3 + 8.4 × NC stable31/32/33) passed. All quality checks passed.

No further changes were required. The PR is ready for review.

[Hydra Security Review — Finding 1/2]
Severity: WARNING
Category: Information Disclosure (CWE-200)
File: lib/Controller/HealthController.phpindex() method, response payload

Observation:
The @PublicPage endpoint returns the exact application version string in every unauthenticated response:

'version' => $this->appManager->getAppVersion(appId: Application::APP_ID),

Any anonymous caller (including external scanners) can fingerprint the exact installed version of Planix and cross-reference it against public CVE databases.

Recommendation:
Consider omitting version from the public response, or restricting it to authenticated callers (e.g., add a separate GET /api/health/full route behind @NoAdminRequired). If version disclosure is acceptable per your threat model, document the decision in the spec.

SAST verdict: No automated tool flagged this — manual finding.

[Hydra Security Review — Finding 2/2]
Severity: WARNING
Category: Infrastructure Topology Disclosure (CWE-497)
File: lib/Controller/HealthController.phpindex() method, response payload

Observation:
The public endpoint exposes whether the openregister app is installed on the server:

'openRegisterAvailable' => $openRegisterAvailable,

Combined with the version field (Finding 1/2), unauthenticated callers receive a complete snapshot of internal application dependencies. An attacker can use this to tailor attacks — e.g., target known OpenRegister vulnerabilities when the flag is true.

Recommendation:
This field is explicitly required by the spec for load balancer use, so removing it may not be appropriate. If retained, document in openspec/changes/status-api/design.md that topology disclosure is an accepted risk. Alternatively, restrict this field to authenticated health consumers (ops teams, monitoring agents) via a bearer token or separate authenticated route.

SAST verdict: No automated tool flagged this — manual finding.

[WARNING] Missing OAS 3.0 specification for GET /api/health

File: lib/Controller/HealthController.php / openspec/changes/status-api/design.md

The Common Ground conventions in the project's CLAUDE.md mandate:

OAS 3.0: OpenAPI Specification required for all new or changed endpoints

No OpenAPI specification has been added for the new GET /api/health endpoint. At minimum, the endpoint contract should be documented in an openapi.yaml (or equivalent), covering:

  • Path /api/healthGET
  • 200 response schema (status: "ok", version: string, openRegisterAvailable: true)
  • 503 response schema (status: "degraded", openRegisterAvailable: false)
  • Security: public (no auth)

Note: The current codebase has no existing OAS document, so this is a systemic gap — but adding the first one alongside the first explicitly-documented public endpoint is the right moment to establish the pattern.

[SUGGESTION] Non-standard @spec tags in phpdoc blocks

File: lib/Controller/HealthController.php lines 19, 40, 52, 64 / tests/unit/Controller/HealthControllerTest.php lines 19, 36, 41

The phpdoc blocks contain @spec openspec/changes/status-api/tasks.md#task-1 in multiple places (class, constructor, method, test class). This is a Hydra builder tracing convention and does not belong in production code:

  • No PHP tooling (PHPDoc, Psalm, PHPStan, IDEs) recognises @spec — it generates noise in documentation output
  • Spec traceability belongs in the PR description and commit messages, not in runtime source files
  • Existing controllers (SettingsController.php, DashboardController.php) do not use this tag

Suggestion: Strip all @spec tags from phpdoc blocks before this PR is merged.

[SUGGESTION] Third commit message doesn't follow convention

Commit: d474bc4browser fix: return bool from setValueString mock callbacks (#96)

The builder commit-message conventions require:

  • Subsequent commits: feat(<scope>): <description> (#issue)
  • Fix commits: fix iteration N: <description> (#issue)

The third commit uses browser fix: which matches neither pattern. It should have been either feat(test): return bool from setValueString mock callbacks (#96) or fix iteration 1: return bool from setValueString mock callbacks (#96).

This is informational only (the commit is already in history). No action required, but future builder runs should enforce the convention consistently.

[SUGGESTION] Degraded-state test doesn't assert version field

File: tests/unit/Controller/HealthControllerTest.phptestIndexReturnsDegradedWhenOpenRegisterUnavailable()

testIndexReturnsDegradedWhenOpenRegisterUnavailable mocks getAppVersion (correctly) but never asserts that $data['version'] is present or correct. The degraded path exercises the same version-retrieval code path as the healthy path, so the omission is low-risk, but full symmetry with the healthy test would strengthen coverage.

Suggested addition at the end of the method:

self::assertSame(expected: '0.2.1', actual: $data['version']);

🛡️ Security Finding — WARNING

File: `lib/Controller/HealthController.php`, line 88
Rule: Information Disclosure — Application Version Exposed on Unauthenticated Endpoint
Severity: WARNING
Category: OWASP A05:2021 — Security Misconfiguration


Finding

The health endpoint returns the application version in its JSON response body:

```php
$data = [
'status' => $status,
'version' => $this->appManager->getAppVersion(appId: Application::APP_ID),
'openRegisterAvailable' => $openRegisterAvailable,
];
```

Because the endpoint is annotated `@PublicPage @NoCSRFRequired`, it requires no authentication. Any unauthenticated actor can call `GET /api/health` and obtain the exact installed version of Planix. This facilitates version fingerprinting — an attacker can cross-reference the version against known CVEs without any credentials.

The `openRegisterAvailable` boolean also leaks internal dependency state, which can aid in targeted attack planning (e.g., knowing that OpenRegister is absent removes a layer an attacker would otherwise have to probe).

Recommendation

Remove or restrict the version field on the public response. Options:

Option A — Omit version entirely (preferred for public endpoints):
```php
$data = [
'status' => $status,
'openRegisterAvailable' => $openRegisterAvailable,
];
```

Option B — Serve detailed payload only to authenticated callers:
Add a second, authenticated action (e.g., `GET /api/health/details`) that returns the full payload including version, and return only `status` from the public endpoint.

Option C — Version as a build-time constant (no enumerable version string):
If version is needed by monitoring systems, pass it through an infrastructure-layer header (e.g., set by the deployment pipeline) rather than embedding it in the application response.

  }
}

Verdict: ⚠️ WARNING — address SEC-001 before merge

The tooling scan is fully clean (Semgrep 0 findings, Gitleaks 0 secrets). The single WARNING was identified through manual review: the public health endpoint leaks the installed application version, enabling unauthenticated version fingerprinting (OWASP A05). No CRITICAL findings were found.

Required action: Remove or restrict the version field as described in the finding comment above. The remainder of the implementation (EUPL-1.2 headers, no credentials committed, proper CSRF annotations, no injection vectors) is correct.

[WARNING] Redundant SettingsService dependency

HealthController injects both SettingsService and IAppManager, but SettingsService::isOpenRegisterAvailable() is a one-liner that delegates to $this->appManager->isInstalled('openregister'). Since IAppManager is already present for getAppVersion(), the SettingsService dependency is unnecessary and adds an extra service to the DI graph.

Fix: Replace $this->settingsService->isOpenRegisterAvailable() with $this->appManager->isInstalled('openregister') and remove the SettingsService constructor parameter and import.

[SUGGESTION] @NoAdminRequired is redundant when @PublicPage is set

@PublicPage already tells Nextcloud that no authentication is required at all — admin or otherwise. Keeping @NoAdminRequired alongside it is harmless but clutters the docblock.

Suggestion: remove @NoAdminRequired from this action.

[WARNING] Missing OAS 3.0 spec and .openspec.yaml tracking file

Two required artefacts are absent from openspec/changes/status-api/:

  1. OAS 3.0 spec — Conduction's architecture rules state: "OAS 3.0: OpenAPI Specification required for all new or changed endpoints." Every other completed change (e.g. tasks, kanban-board, admin-user-settings) ships a specs/ directory with the API contract. The status-api change is missing this entirely. A minimal spec for GET /api/health should be added at openspec/changes/status-api/specs/health.yaml (or equivalent).

  2. .openspec.yaml tracking file — All other change directories contain a .openspec.yaml metadata file (schema: spec-driven, created date, etc.). The status-api directory does not, which will cause openspec status and pipeline tooling to treat this change as untracked.

Fix: Add openspec/changes/status-api/.openspec.yaml and at minimum a minimal OAS path entry for the health endpoint.

Hydra Builder — Fix iteration 2

Fixed findings:

  • [WARNING] SEC-001 — Application version exposed on unauthenticated endpoint: Removed version field from the GET /api/health response body. Version disclosure is now prevented for unauthenticated callers (OWASP A05 / CWE-200). Updated testIndexResponseContainsAllRequiredFields to assert version key is absent.
  • [WARNING] F-001 — Redundant SettingsService dependency: Replaced $this->settingsService->isOpenRegisterAvailable() with $this->appManager->isInstalled('openregister') directly. Removed SettingsService from constructor injection, imports, and the test's mock setup.
  • [WARNING] F-002 — SPDX header placed after docblock (HealthController.php): Moved SPDX-License-Identifier: EUPL-1.2 and Copyright to the first two lines of the file's /** docblock. This places the identifier in the first comment block (satisfying REUSE scanners) while keeping /** style (satisfying PHPCS).
  • [WARNING] F-003 — SPDX header placed after docblock (HealthControllerTest.php): Same fix as F-002 applied to the test file.
  • [WARNING] F-004 — Missing OAS 3.0 spec and .openspec.yaml: Added openspec/changes/status-api/.openspec.yaml (tracking file) and openspec/changes/status-api/specs/health.yaml (OAS 3.0 path definition for GET /api/health, including 200/503 response schemas and documented accepted risk for openRegisterAvailable topology disclosure per SEC-002).

Remaining SUGGESTIONs (not addressed — informational only):

  • F-05 / F-02 (code review): @NoAdminRequired redundant with @PublicPage
  • Non-standard @spec phpdoc tags in production code
  • Third commit message does not follow convention (historical, cannot change)
  • Degraded-state test omits version field assertion (moot — version field removed)

Hydra Security Review — Finding SEC-INFO-001

Severity: INFORMATIONAL
File: lib/Controller/HealthController.php (line 86)
CWE: CWE-497 — Exposure of Sensitive System Information to an Unauthorized Control Sphere
OWASP: A05:2021 — Security Misconfiguration

Observation

The openRegisterAvailable field in the public health response reveals whether the OpenRegister Nextcloud app is installed on this instance. An unauthenticated caller can infer the internal app topology from this field.

Assessment

This is a documented and accepted risk. The OAS spec at openspec/changes/status-api/specs/health.yaml (lines 65–67) explicitly records this as SEC-002 / CWE-497 with the rationale that the field is required for load balancer routing decisions.

The implementation shows deliberate security thinking: a previous version included the app version string (which would have been a higher-severity CWE-200 fingerprinting risk — see commit 3d37470), and that was correctly removed before this PR was finalised.

Verdict

No action required. Accepted risk, correctly documented.

Hydra Security Review — Finding SEC-INFO-002

Severity: INFORMATIONAL
File: lib/Controller/HealthController.php (line 68)
Category: Annotation hygiene

Observation

The index() method carries three annotations: @PublicPage, @NoCSRFRequired, and @NoAdminRequired.

In the Nextcloud AppFramework, @PublicPage already bypasses all authentication and session checks — it implies both CSRF exemption and no admin requirement. The @NoAdminRequired annotation is therefore redundant on a @PublicPage endpoint.

Assessment

This is not a security vulnerability; the effective access control is correct. Redundant annotations can mislead future maintainers into believing admin-only access is being explicitly waived, rather than understanding that the entire endpoint is public.

Verdict

No action required for merge. Suggested clean-up: remove @NoAdminRequired in a follow-up commit to reduce annotation noise.

Hydra Security Review — Finding SEC-INFO-003

Severity: INFORMATIONAL (pre-existing, out of scope for this PR)
File: appinfo/routes.php (line 14)
Category: Dead route / missing controller

Observation

appinfo/routes.php registers a route metrics#index → GET /api/metrics, but no MetricsController exists in lib/Controller/. The only controllers present are DashboardController, SettingsController, and the newly added HealthController.

Assessment

This pre-dates this PR and is therefore out of scope here. However, it is worth flagging because:

  1. Nextcloud will return an unhandled exception for any request to GET /api/metrics, which could leak a stack trace depending on the environment's debug configuration.
  2. If a MetricsController is added in a future PR, it should receive a dedicated security review — metrics endpoints frequently expose sensitive operational data.

Verdict

Out of scope for this PR. Recommend opening a follow-up issue to either implement MetricsController with appropriate access controls or remove the dead route.

[WARNING] — Acceptance criterion 1 says the endpoint should return status, version, and openRegisterAvailable, but the implementation (correctly, per SEC-001/CWE-200) omits version. The test even asserts assertArrayNotHasKey(key: 'version', ...). The criterion text must be updated to reflect the actual design decision, e.g.:

- [x] `GET /api/health` returns JSON with `status` and `openRegisterAvailable` fields (`version` intentionally omitted — SEC-001/CWE-200)

Leaving a criterion that the implementation provably fails misleads future maintainers about whether the spec was met.

[WARNING] PR description body — The summary paragraph states:

version is not returned by the endpoint. This was deliberately removed (SEC-001/CWE-200) but the PR body was not updated. The description should be corrected to accurately document what the endpoint returns, or future readers will assume a contract that does not exist.

Hydra Security Review — Clyde Barcode

Scanners run: Semgrep (p/security-audit, p/secrets, p/owasp-top-ten) · Gitleaks · Trivy


SUGGESTION — Infrastructure topology disclosure via openRegisterAvailable (CWE-497)

File: lib/Controller/HealthController.php · openapi.yaml

The public response includes openRegisterAvailable, which discloses whether the OpenRegister Nextcloud app is installed on this instance to any unauthenticated caller. This is a mild information disclosure (OWASP A05:2021 / CWE-497).

Note: This is already acknowledged and documented as SEC-002 / CWE-497 in openspec/changes/status-api/specs/health.yaml as an accepted risk with a clear rationale (load-balancer routing decisions). The spec explicitly states: "Infrastructure topology disclosure is an accepted risk for this public monitoring endpoint."

Since the trade-off is documented and intentional, this is informational only. No code change required.


SUGGESTION — No application-level rate limiting on the public endpoint

File: lib/Controller/HealthController.php (line 72)

GET /api/health requires no authentication and performs an IAppManager::isInstalled() call on every request. Without rate limiting, a flood of requests could cause unnecessary load on the app manager. This is typically addressed at the infrastructure layer (reverse proxy / load balancer), which is the appropriate place for it in a Nextcloud app context.

No code change required — noting for operations team awareness.

Hydra Code Reviewer — Finding W-001
Severity: WARNING
File: openapi.yaml (root) vs openspec/changes/status-api/specs/health.yaml

Two OAS 3.0 documents describe the same GET /api/health endpoint but use different schema structures:

  • Root openapi.yaml splits into two schemas (HealthOk / HealthDegraded), each with boolean-constrained enum values (enum: [true] / enum: [false]).
  • Spec health.yaml uses a single unified HealthResponse schema with status: enum: [ok, degraded] and a plain type: boolean field.

The root openapi.yaml is the consumer-facing document; the spec health.yaml is the better-modelled one. Having two diverging specs creates a maintenance risk and can confuse tooling (e.g. code generators, linters).

Recommendation: Consolidate. Either adopt the unified HealthResponse schema from health.yaml into openapi.yaml, or remove the redundant split-schema approach. Boolean enum: [true]/enum: [false] constraints are valid OAS but non-standard and should be dropped in favour of plain type: boolean.

Hydra Code Reviewer — Finding W-002
Severity: WARNING
File: openapi.yaml, lines 71–72 and 88–89

openRegisterAvailable:
  type: boolean
  enum:
    - true   # HealthOk schema
openRegisterAvailable:
  type: boolean
  enum:
    - false  # HealthDegraded schema

Using enum to constrain a boolean to a single value ([true] or [false]) is non-standard and is likely to cause warnings or unexpected behaviour in OAS validators and code generators. A boolean field by definition only holds true or false; there is no value in further constraining it.

Recommendation: Remove the enum constraints from both openRegisterAvailable properties and rely solely on type: boolean. The per-status distinction is already captured by the status field enum (ok / degraded) and the HTTP status code.

Hydra Code Reviewer — Finding S-001
Severity: SUGGESTION
File: lib/Controller/HealthController.php, line 67

 * @PublicPage
 * @NoCSRFRequired
 * @NoAdminRequired

@NoAdminRequired is redundant when @PublicPage is already present. @PublicPage in Nextcloud's AppFramework bypasses authentication entirely, which implicitly satisfies the no-admin-required constraint. The annotation adds no behavioural effect and slightly bloats the docblock.

Recommendation: Remove @NoAdminRequired from the index() docblock.

Severity: SUGGESTION
File: lib/Controller/HealthController.php, line 79

if ($openRegisterAvailable === true) {

IAppManager::isInstalled() is declared to return bool. A strict identity check (=== true) against a known boolean is unnecessary — it reduces readability without adding type safety. Prefer:

if ($openRegisterAvailable) {

Hydra Code Reviewer — Finding I-001
Severity: INFORMATIONAL
Files: tests/unit/Controller/HealthControllerTest.php (and all other unit tests)

The 3 new HealthControllerTest tests fail when run outside the Docker environment because OCP\IRequest (and other Nextcloud framework classes) are not loadable via the Composer autoloader in isolation. This is not introduced by this PR — the baseline development branch already has 11 test errors (12 tests) for the same reason. The bootstrap file (tests/bootstrap-unit.php) is designed to run inside a Docker container where lib/base.php is available.

This is a pre-existing infrastructure constraint, not a regression. Confirming that the 3 new tests are structurally sound and will pass once the full Nextcloud environment is present.

Hydra Security Review — Automated Scan Results

Reviewer: Clyde Barcode (Hydra Security Reviewer)
PR: #98feat: add GET /api/health endpoint
Scan date: 2026-04-06

Automated SAST / Secret Detection

Tool Ruleset Findings
Semgrep p/security-audit, p/secrets, p/owasp-top-ten ✅ 0 findings
Gitleaks secret detection ✅ 0 findings
Trivy ⬜ not present

All automated scans are clean.


Manual Review — Changed Files

lib/Controller/HealthController.php

  • @PublicPage + @NoCSRFRequired + @NoAdminRequired annotations are correct and intentional for a monitoring endpoint.
  • No user-controlled input is accepted; no SQL, file I/O, or shell execution — no injection surface.
  • Version is intentionally absent from the JSON response. The PR description and inline comments correctly cite SEC-001 / CWE-200 / OWASP A05:2021. ✅

openapi.yaml

  • security: [] correctly documents the unauthenticated nature of the endpoint.
  • version: 0.2.1 in the info block is API version metadata in a documentation artifact — not runtime version disclosure. ✅

openspec/changes/status-api/specs/health.yaml

  • The openRegisterAvailable boolean exposes minor infrastructure topology (whether the openregister Nextcloud app is installed). The spec correctly documents this as SEC-002 / CWE-497 — accepted risk, with rationale (load balancer routing). ✅

tests/unit/Controller/HealthControllerTest.php

  • Unit test file. No security concerns. Includes an explicit assertion that version is absent from the response (assertArrayNotHasKey), which is good security-aware testing practice. ✅

tests/unit/Service/SettingsServiceTest.php

  • Minor mock callback fixes. No security concerns. ✅

Observations (INFO — not blocking)

INFO-1 · No application-layer rate limiting on the public endpoint
GET /api/health is unauthenticated and does no I/O beyond a single isInstalled() call. Rate limiting is conventionally handled at the infrastructure layer (load balancer / WAF / Nginx), which is the appropriate place here. No remediation required at the application level, but operators should ensure the endpoint is behind infrastructure-level throttling in production.

INFO-2 · Infrastructure topology via openRegisterAvailable
The field reveals whether the openregister Nextcloud app is installed. This is a deliberate accepted risk documented in the spec (SEC-002 / CWE-497). No remediation required.

[WARNING] operationId inconsistency between OAS documents

openapi.yaml declares:

operationId: health.index

openspec/changes/status-api/specs/health.yaml declares:

operationId: health_index

The Nextcloud route name is health#index, which maps to the dot-separated convention health.index. The spec file should be updated to use health.index to match the canonical OAS document and the Nextcloud routing convention.

[WARNING] Dual schemas in openapi.yaml diverge from spec

openapi.yaml defines two schemas — HealthOk and HealthDegraded — each with a single-value enum for openRegisterAvailable:

HealthOk:
  properties:
    openRegisterAvailable:
      type: boolean
      enum: [true]
HealthDegraded:
  properties:
    openRegisterAvailable:
      type: boolean
      enum: [false]

The authoritative spec file (openspec/changes/status-api/specs/health.yaml) uses a single HealthResponse schema that accepts both states:

HealthResponse:
  properties:
    openRegisterAvailable:
      type: boolean   # no enum restriction

The split-schema approach in openapi.yaml is technically valid OAS 3.0 (and useful for discriminated unions), but it creates maintenance overhead and diverges from the spec. The single-schema approach from the spec file is cleaner and should be used in openapi.yaml for consistency.

[SUGGESTION] @NoAdminRequired is redundant on a @PublicPage action

 * @PublicPage
 * @NoCSRFRequired
 * @NoAdminRequired   // <-- redundant

@PublicPage instructs the Nextcloud middleware to bypass all authentication checks entirely — the admin check is never reached. Removing @NoAdminRequired reduces annotation noise without changing behaviour.

Also note: Nextcloud 31 (the version targeted by this codebase) introduces PHP 8 native attributes as the preferred replacement for these docblock annotations (#[PublicPage], #[NoCSRFRequired]). Docblock annotations remain supported but are deprecated. The rest of the codebase uses the old style too, so no action is required on this PR, but a follow-up migration to PHP attributes would align with NC31 best practice.

Hydra Code Review — PR #98 feat: add GET /api/health endpoint

Reviewer: Juan Claude van Damme, Hydra Code Reviewer, Conduction B.V.
Date: 2026-04-06
Branch: feature/96/status-apidevelopment


Summary of findings

Severity Count Finding
CRITICAL 0
WARNING 2 operationId inconsistency; dual-schema OAS divergence
SUGGESTION 1 Redundant @NoAdminRequired + note on NC31 attribute migration

What was checked

  • Cloned feature/96/status-api and ran composer cs:check scoped to all PR-changed files — no errors on HealthController.php, HealthControllerTest.php, or SettingsServiceTest.php
  • PHPUnit: test infrastructure requires a full Nextcloud installation (OCP interfaces unavailable without the runtime). All 14 pre-existing test errors are environment-related and not regressions introduced by this PR. The one passing test (PlanixTest::testPlaceholder) continues to pass.
  • Reviewed all changed files: HealthController.php, openapi.yaml, openspec/changes/status-api/specs/health.yaml, tasks.md, design.md, HealthControllerTest.php, SettingsServiceTest.php
  • Verified route registration: health#index/api/health present in appinfo/routes.php (already in the development base branch — not introduced by this PR, which is fine)

Positive observations

  • Security-conscious design: omitting version from the public response to prevent unauthenticated version fingerprinting (CWE-200 / OWASP A05) is the correct call and is well-documented throughout
  • Direct dependency use: replacing a SettingsService indirection with IAppManager::isInstalled() directly is cleaner and avoids leaking service complexity into the controller
  • Test coverage: three test methods covering healthy (200), degraded (503), and field completeness (including absence of version) — solid baseline coverage
  • SettingsServiceTest.php fix: correcting the mock callback return type from void to bool is the right fix for the NC31 IAppConfig::setValueString() signature change
  • EUPL-1.2 headers: correctly applied on all new PHP files
  • PSR-12 / PHPCS: all PR-changed files pass the project's phpcs.xml standard cleanly

WARNING findings

See inline comments on the diff for details:

  1. operationId inconsistencyopenapi.yaml uses health.index but specs/health.yaml uses health_index. Fix: align both to health.index (Nextcloud dot-convention)
  2. Dual schemas in openapi.yamlHealthOk / HealthDegraded split diverges from the single HealthResponse schema in the authoritative spec file, creating maintenance overhead

Both warnings are confined to the OAS documents and do not affect runtime behaviour, but they will cause confusion for API consumers and spec tooling.
