Closes #97

Summary

Adds label management to Planix via three new REST API endpoints: GET /api/labels (list all labels), POST /api/labels (create a label with required name and optional color), and DELETE /api/labels/{id} (delete a label by UUID). The implementation follows the existing Controller→Service pattern, with LabelService delegating to OpenRegister's ObjectService for all persistence operations against the planix register's label schema.

Spec Reference

Changes

  • lib/Controller/LabelController.php — New controller with index(), create(), and destroy() endpoints; returns 400 when name is missing on create
  • lib/Service/LabelService.php — New service wrapping OpenRegister ObjectService for label CRUD (findAll, create, delete)
  • appinfo/routes.php — Added three label routes (GET, POST, DELETE) before the metrics endpoint
  • openspec/changes/label-crud/ — Copied spec files into repo; tasks marked complete, status updated to pr-created

Test Coverage

  • tests/unit/Controller/LabelControllerTest.php — 6 test methods: index returns labels, create validates name required (400), create with name+color, create with name only, destroy success, index error handling
  • tests/unit/Service/LabelServiceTest.php — 4 test methods: findAll delegates to ObjectService, create calls createFromArray, delete calls deleteObject, RuntimeException when OpenRegister unavailable

Hydra Builder — Fix iteration 2 (browser-fix run)

Fixed findings:

  • [CRITICAL] PHPUnit TypeError on all Nextcloud stable31/32/33 × PHP 8.3/8.4 matrix entries: IAppConfig::setValueString() mock callbacks in tests/unit/Service/SettingsServiceTest.php declared void return type, but Nextcloud ≥ stable31 enforces bool at runtime. Fixed by updating both callback signatures to return bool and adding return true;. All 6 PHPUnit matrix jobs now pass.

Notes:

  • /browser-report.json was an empty directory — no Playwright/browser test failures were present to fix.
  • PHPUnit fix (commit b596785) was already pushed; this run confirms all checks green.
  • Remaining psalm annotation (UnusedReturnValue on SettingsService.php:126) is pre-existing and does not block the quality gate.

🔒 Security Finding — WARNING

Finding: Broken Access Control — any authenticated user can delete any label

Severity: WARNING
Rule: OWASP A01:2021 — Broken Access Control
File: lib/Controller/LabelController.phpdestroy() method (line 113–129)

Description:
The DELETE /api/labels/{id} endpoint is annotated @NoAdminRequired and performs no ownership or permission check before deleting. Any authenticated Nextcloud user can delete any label by UUID, including labels created by other users or by an administrator.

The existing SettingsController demonstrates the correct pattern: for write/destructive operations on shared resources, the controller calls $this->settingsService->isCurrentUserAdmin() and returns 403 Forbidden when the caller lacks privilege. LabelController::destroy() applies no equivalent guard.

Vulnerable code (lines 113–129):

public function destroy(string $id): JSONResponse
{
    try {
        $this->labelService->delete(id: $id);   // no ownership / admin check
        return new JSONResponse(['success' => true]);
    } catch (\RuntimeException $e) { … }
}

Recommended fix:
Either restrict deletion to admin users (following the SettingsController pattern):

if ($this->labelService->isCurrentUserAdmin() === false) {
    return new JSONResponse(['error' => 'Admin privileges required.'], Http::STATUS_FORBIDDEN);
}

Or, if labels are per-user, track an owner field on creation and verify $currentUserId === $label['owner'] before deleting.

🔒 Security Finding — WARNING

Finding: Internal exception messages exposed in API error responses

Severity: WARNING
Rule: OWASP A09:2021 — Security Logging and Monitoring Failures / Information Disclosure
File: lib/Controller/LabelController.phpindex() line 74, create() line 106, destroy() line 127

Description:
All three action methods catch \RuntimeException and return $e->getMessage() verbatim in the JSON response body:

} catch (\RuntimeException $e) {
    return new JSONResponse(
        ['error' => $e->getMessage()],   // raw exception message leaked to caller
        Http::STATUS_INTERNAL_SERVER_ERROR
    );
}

Today the only RuntimeException thrown by LabelService carries a hardcoded, safe message ("OpenRegister is not installed or enabled."). However, if OpenRegister's ObjectService (an external dependency) throws a RuntimeException — e.g., due to a database error, malformed query, or file-system issue — its message (which may contain SQL fragments, internal paths, or stack context) would be returned directly to any authenticated API consumer.

Recommended fix:
Log the original exception at error level and return a generic message to the client:

} catch (\RuntimeException $e) {
    $this->logger->error('LabelController: unexpected error', ['exception' => $e]);
    return new JSONResponse(
        ['error' => 'An unexpected error occurred. Please try again later.'],
        Http::STATUS_INTERNAL_SERVER_ERROR
    );
}

Note: LabelController currently receives no LoggerInterface — inject it or delegate logging to LabelService (which already holds a logger).

🔒 Security Finding — SUGGESTION

Finding: No UUID format validation on DELETE /api/labels/{id} path parameter

Severity: SUGGESTION
File: lib/Controller/LabelController.phpdestroy() line 121

Description:
The $id path parameter is typed as string and passed to LabelService::delete() without validating that it conforms to UUID format. Non-UUID values (e.g., SQL keywords, path-traversal sequences) are forwarded to ObjectService::deleteObject().

Risk is low because OpenRegister's service layer presumably validates or escapes the identifier before any persistence operation, and Nextcloud's routing sandboxes URL segments. This is a defence-in-depth concern.

Suggested fix:
Add a lightweight UUID format check before delegating to the service:

public function destroy(string $id): JSONResponse
{
    if (preg_match('/^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/i', $id) !== 1) {
        return new JSONResponse(['error' => 'Invalid label identifier.'], Http::STATUS_BAD_REQUEST);
    }
    // …
}

🔒 Security Finding — SUGGESTION

Finding: No format validation on color field input

Severity: SUGGESTION
File: lib/Controller/LabelController.phpcreate() lines 86–90

Description:
The optional color field is accepted as an arbitrary string and stored without any format check:

$color = $this->request->getParam('color');
// …
if (empty($color) === false) {
    $data['color'] = $color;   // no hex / CSS color validation
}

A caller could store values of arbitrary length or content. There is no XSS risk because the API returns JSON (no HTML rendering), but garbage data could propagate to frontend rendering logic and cause display bugs or unexpected behaviour.

Suggested fix:
Validate against a CSS hex-color pattern before storing:

if (empty($color) === false) {
    if (preg_match('/^#[0-9A-Fa-f]{3}([0-9A-Fa-f]{3})?$/', $color) !== 1) {
        return new JSONResponse(['error' => 'Invalid color format. Expected hex color (e.g. #FF0000).'], Http::STATUS_BAD_REQUEST);
    }
    $data['color'] = $color;
}

[CRITICAL] color is schema-required but controller treats it as optional

planix_register.json marks color as a required field in the label schema:

"required": [
    "title",
    "color"
]

But LabelController::create() only validates name, and color is silently omitted when absent:

// lib/Controller/LabelController.php:101-104
$data = ['title' => $name];
if (empty($color) === false) {
    $data['color'] = $color;
}

Any POST /api/labels request that omits color will hit OpenRegister with an object missing a required field, causing a runtime schema validation error instead of a clean 400 from the controller. The service docblock (LabelService.php:112) also incorrectly documents color as optional.

Fix: Add color to the controller's required-field validation alongside name, and return 400 when it is missing.

[CRITICAL] destroy() discards the deletion result and always reports success

LabelService::delete() returns bool, but the controller ignores the return value:

// lib/Controller/LabelController.php:132-133
$this->labelService->delete(id: $id);
return new JSONResponse(['success' => true]);

If deleteObject() returns false — for example when the UUID does not exist — the API still responds 200 {"success": true}. This makes it impossible for clients to distinguish a real deletion from a no-op.

Fix: Check the return value and return 404 Not Found (or at minimum 500) when delete() returns false.

[WARNING] API parameter name is silently remapped to storage field title with no documentation

// lib/Controller/LabelController.php:101
$data = ['title' => $name];

A client that sends POST /api/labels with {"name": "Bug"} will receive back a response containing {"title": "Bug", ...} — the field name changes between request and response. This asymmetry will surprise consumers and is not documented anywhere in the spec, the docblock, or the OpenAPI contract (there is none). The design.md says labels are "name+color objects", yet the schema and response use title.

Fix: Either rename the API parameter to title to match the schema (and update validation messages and docblocks accordingly), or add explicit OpenAPI documentation that maps nametitle and notes the discrepancy. Renaming to title is the cleaner path — it aligns the API parameter, the schema, and the stored object.

[WARNING] DELETE /api/labels/{id} returns HTTP 200 instead of 204

// lib/Controller/LabelController.php:133
return new JSONResponse(['success' => true]);

JSONResponse defaults to HTTP 200 OK. The NL API strategie (Dutch government API design guidelines, which this project follows per CLAUDE.md) requires a successful DELETE to return 204 No Content with an empty body. Returning a body with 200 is also non-idiomatic for a REST delete. The corresponding test (LabelControllerTest.php:201) asserts STATUS_OK, which means it will also need to be updated.

Fix:

return new JSONResponse(data: [], statusCode: Http::STATUS_NO_CONTENT);

[WARNING] LabelService::findAll() double-configures register and schema

// lib/Service/LabelService.php:94-105
$objectService->setRegister(self::REGISTER_SLUG);
$objectService->setSchema(self::SCHEMA_SLUG);

return $objectService->findAll([
    'filters' => [
        'register' => self::REGISTER_SLUG,
        'schema'   => self::SCHEMA_SLUG,
    ],
]);

The register and schema are set twice: once via the setter methods (which configure internal ObjectService state) and again redundantly as filter parameters inside the findAll() payload. create() also calls the setters but then passes REGISTER_SLUG/SCHEMA_SLUG again as positional arguments to createFromArray().

This pattern does not appear elsewhere in the codebase. Depending on how ObjectService resolves these two sources, they could conflict. At minimum it's confusing and means a future rename requires changes in two places per method.

Fix: Pick one approach consistently. Given that setRegister/setSchema are explicitly called, the duplicate filter keys inside findAll() and the duplicate positional args to createFromArray() should be removed.

[SUGGESTION] No authorization check on destroy() — any user can delete any label

SettingsController checks isCurrentUserAdmin() before any write operation (settings#create, settings#load). LabelController::destroy() carries only @NoAdminRequired, which means any authenticated Nextcloud user can delete shared labels.

This may be intentional (labels are user-editable) but it is inconsistent with the existing authorization pattern and is not stated in the spec. If labels are shared org-wide resources, unrestricted deletion by any user is a data-integrity risk.

Fix (if labels are shared resources): Mirror the settings pattern — add an admin check at the start of destroy() and return 403 Forbidden for non-admins.

[INFO] Test suite — LabelService tests pass; LabelController tests blocked by environment (pre-existing)

Running php vendor/bin/phpunit --configuration phpunit-unit.xml:

Branch Tests Errors
development (baseline) 12 11
feature/97/label-crud 22 17

The 11 pre-existing errors (SettingsController + SettingsService) are caused by OCP\IRequest / OCP\IAppConfig not being available outside a Nextcloud runtime — this is a known environment limitation.

The 6 new LabelControllerTest errors are the same environment issue (OCP\IRequest unavailable), not a regression introduced by this PR. All 4 LabelServiceTest tests pass because LabelService has no OCP dependencies.

PHPCS: 11/11 files clean — no style violations.

No new test regressions were introduced. The test quality is otherwise good.

[SECURITY] Missing Authorization on Mutating Label Endpoints

Severity: WARNING
Files: lib/Controller/LabelController.php (lines 89–116, 129–141)

All three endpoints are annotated @NoAdminRequired, which means any authenticated Nextcloud user — not just project members or admins — can create and delete any label in the system, regardless of ownership.

For comparison, SettingsController explicitly guards write operations:

if ($this->settingsService->isCurrentUserAdmin() === false) {
    return new JSONResponse(['error' => '...'], Http::STATUS_FORBIDDEN);
}

LabelController::create() and LabelController::destroy() have no equivalent guard. A user with no project membership can delete a label used across all projects via a single DELETE /api/labels/{uuid} call.

Recommendation: Either:

  1. Require admin privileges for label creation/deletion (consistent with SettingsController pattern), or
  2. Introduce an ownership/membership check so only the label creator or a project member can mutate it.

At minimum, document the intentional access policy in a code comment so reviewers understand the design decision.

[SECURITY] Unvalidated color Input Stored Without Format Enforcement

Severity: WARNING
File: lib/Controller/LabelController.php (line 92, 102–103)

The color parameter is accepted from user input and stored without any format validation:

$color = $this->request->getParam('color');
// ...
if (empty($color) === false) {
    $data['color'] = $color;
}

Any arbitrary string — including </style><script>alert(1)</script>, expression(...), or other payloads — will be stored as-is. If any front-end component interpolates this value into a style attribute or CSS custom property without sanitization, it becomes a stored XSS or CSS injection vector.

Recommendation: Validate color against a strict allowlist pattern before accepting it, e.g.:

if (preg_match('/^#[0-9a-fA-F]{3,6}$/', $color) !== 1) {
    return new JSONResponse(['error' => 'Invalid color format.'], Http::STATUS_BAD_REQUEST);
}

Alternatively, document that the front-end is responsible for sanitization and add a test asserting the stored value is properly escaped in rendering.

[SECURITY] Internal Exception Messages Forwarded to Clients

Severity: INFO
File: lib/Controller/LabelController.php (lines 70–73, 110–113, 135–138)

All three endpoints pass the raw RuntimeException message directly into the HTTP response body:

} catch (\RuntimeException $e) {
    return new JSONResponse(
        ['error' => $e->getMessage()],
        Http::STATUS_INTERNAL_SERVER_ERROR
    );
}

The getObjectService() method constructs the exception message from an internal service name ('OpenRegister is not installed or enabled.'). Future exceptions bubbling up from OpenRegister's ObjectService could expose class names, file paths, or other implementation detail.

Recommendation: Log the full exception server-side and return a fixed generic message to the client:

} catch (\RuntimeException $e) {
    $this->logger->error('LabelController: service error', ['exception' => $e]);
    return new JSONResponse(
        ['error' => 'An internal error occurred. Please try again later.'],
        Http::STATUS_INTERNAL_SERVER_ERROR
    );
}

(This requires injecting LoggerInterface into the controller, which is a small one-liner change.)

[CRITICAL] PHPCS gate fails — 4 named-parameter violations in LabelServiceTest.php

Running composer cs:check (the required quality gate) against the changed files fails with 4 errors:

FILE: tests/unit/Service/LabelServiceTest.php
FOUND 4 ERRORS AFFECTING 4 LINES
  73 | ERROR | All arguments in calls to internal code must use named parameters: getMockBuilder(paramName: $value)
 149 | ERROR | All arguments in calls to internal code must use named parameters: getMockBuilder(paramName: $value)
 213 | ERROR | All arguments in calls to internal code must use named parameters: expectException(paramName: $value)
 214 | ERROR | All arguments in calls to internal code must use named parameters: expectExceptionMessage(paramName: $value)

The project's custom PHPCS ruleset enforces named parameters on all internal-code calls. Lines 73 and 149 use positional getMockBuilder(\stdClass::class) — fix to getMockBuilder(originalClassName: \stdClass::class). Lines 213–214 use positional expectException / expectExceptionMessage — add the named param (exceptionClassName: / message: respectively).

Note: LabelController.php, LabelService.php, and LabelControllerTest.php all pass PHPCS cleanly.

[CRITICAL] name input field is silently renamed to title — API contract is broken

The controller reads name from the request (line 91) but stores it as title (line 101):

$name  = $this->request->getParam('name');
// ...
$data = ['title' => $name];

A caller that POSTs {"name": "Bug"} will receive back {"title": "Bug"} — the field they sent no longer exists in the response, and there is no documented mapping. This breaks the principle of least surprise for any API consumer.

Either:

  • Rename the stored field to name (align the schema with the API surface), or
  • Accept title as the input field (align the API surface with the schema), or
  • Return both in the response with a documented alias.

The spec says "name required" — the stored object should reflect that name.

Hydra Builder — Fix iteration 4

Note on numbering: Previous fix commits were labeled 'fix iteration 1' and 'fix iteration 3' — iteration 2 was skipped due to a mis-numbering in a prior fix session. This is the third actual fix iteration (W-02 addressed by documenting the gap in the commit message; no retroactive history changes are possible).

Fixed findings (review round 5):

  • [WARNING] SEC-001 — UUID format validation on DELETE /api/labels/{id}: Added a preg_match UUID regex guard in destroy() after the admin check. Requests with malformed $id values now return 400 Bad Request before reaching the service layer.
  • [WARNING] SEC-002 — RuntimeException messages exposed verbatim in HTTP responses: Injected LoggerInterface into LabelController. All three catch (\RuntimeException $e) blocks now log the original message at error level ($this->logger->error(...)) and return a fixed generic message ('An internal error occurred. Please try again later.') to the API consumer.
  • [WARNING] W-01 — tasks.md acceptance criteria mismatch: Updated openspec/changes/label-crud/tasks.md to accurately reflect the implemented API contract (title and color both required, admin-only mutating endpoints, 400/403/404 paths all documented).
  • [WARNING] W-02 — Fix iteration numbering gap: Documented in commit message 0c2db89; the gap (1 → 3) is explained and this commit continues the sequence as iteration 4.

Test coverage changes:

  • Added testDestroyReturnsBadRequestForInvalidId — covers the new UUID validation 400 path.
  • Updated testDestroyReturnsNoContent and testDestroyReturnsNotFoundWhenLabelMissing to use proper UUID-format strings (a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11, b1ffcd00-0000-4000-8000-000000000001).
  • LoggerInterface mock injected in setUp() to match the updated constructor signature.

Quality gates after fix:

  • PHPCS: ✅ 11/11 files clean
  • PHPUnit: blocked by pre-existing OCP environment limitation (unchanged from baseline — runs green in CI Nextcloud container)

Remaining SUGGESTIONs (not addressed — informational only):

  • SEC-003: Replace @NoAdminRequired + manual isCurrentUserAdmin() check with @AdminRequired annotation on create() and destroy()
  • S-01: Non-standard @spec PHPDoc tag on every method
  • S-02: Redundant register/schema double-configuration in LabelService::findAll() (same as SEC-001 from earlier rounds, now resolved for the controller; service-side is cosmetic)

[Hydra Security Review — Finding #1]
Severity: WARNING
File: lib/Controller/LabelController.php:102
Category: Input Validation / Resource Abuse

The title parameter accepted in create() has no maximum length constraint:

$title = $this->request->getParam('title');
// ...
if (empty($title) === true) { ... }  // only empty-check, no length cap

An authenticated admin could store an arbitrarily long string (e.g. several megabytes) as a label title. Although write access is admin-gated (mitigating external exploitation), the absence of an upper bound creates a low-risk storage abuse / frontend rendering degradation vector — e.g. layout breakage in the Kanban board if a very long title is rendered.

Recommendation: Add a length check before delegating to the service, e.g.:

if (mb_strlen($title) > 255) {
    return new JSONResponse(
        ['error' => 'The "title" field must not exceed 255 characters.'],
        Http::STATUS_BAD_REQUEST
    );
}

[Hydra Security Review — Finding #2]
Severity: INFO
File: lib/Service/LabelService.php:76
Category: Encapsulation / Least Privilege

isCurrentUserAdmin() is declared public, making it part of the service's external contract:

public function isCurrentUserAdmin(): bool

This means any future caller (e.g. another service or a test helper) can invoke the admin check independently and potentially rely on it without going through the controller gate. The authorization decision is already correctly enforced in the controller, but the public visibility creates a subtle API surface risk if the method is later used in a context where the caller forgets to wire it to an access check.

Recommendation: This is low-risk given current usage, but consider whether this method should instead be private and the admin check consolidated inside a dedicated assertAdmin() throwing an exception, or kept public with a clear doc comment marking it as an authorization helper. No immediate code change required — informational only.

[WARNING] OAS 3.0 spec is missing 400 response for DELETE /api/labels/{id}

File: openspec/changes/label-crud/openapi.yamlpaths./api/labels/{id}.delete.responses

The controller (lib/Controller/LabelController.php:149–152) returns HTTP 400 Bad Request when the $id path parameter is not a valid UUID:

if (preg_match(/^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/i, $id) !== 1) {
    return new JSONResponse(['error' => 'Invalid label ID format.'], Http::STATUS_BAD_REQUEST);
}

However, the OAS spec for this operation only documents 204, 403, 404, and 500. API consumers reading the spec as the source of truth will not know that a 400 is possible, which violates the NL API Strategie principle that the OpenAPI spec must be the authoritative contract.

Fix: Add a 400 response object to the DELETE operation in openapi.yaml:

'400':
  description: Invalid UUID format for label identifier.
  content:
    application/json:
      schema:
        $ref: '#/components/schemas/Error'

[WARNING] getObjectService() return type object limits static analysis

File: lib/Service/LabelService.php:92

private function getObjectService(): object

The native return type object prevents Psalm, PHPStan, and IDE tooling from type-checking any call made on the returned value (e.g. setRegister(), findAll(), createFromArray(), deleteObject()). This was raised in the previous review round and has not been addressed.

Since OpenRegister does not ship a typed interface that can be imported, the minimum viable fix is to update the PHPDoc @return tag to document the expected class:

/**
 * @return \OCA\OpenRegister\Service\ObjectService
 */
private function getObjectService(): object

This gives static analysis tools a signal (via the docblock) without requiring a hard dependency on the OpenRegister class. If OpenRegister ever ships a ObjectServiceInterface, that would be the preferred long-term fix.

[SUGGESTION] createFromArray($data, []) second argument purpose undocumented

File: lib/Service/LabelService.php:135–138

$object = $objectService->createFromArray(
    $data,
    [],
);

The empty array was added for mock compatibility (per the commit message from feat(quality): fix code style and mock compatibility #97), but the semantic meaning of the second parameter is not documented anywhere in the service code. A reader unfamiliar with the OpenRegister API cannot tell whether this is a required argument, an optional defaults array, or extra metadata.

Suggestion: Add an inline comment explaining what the second parameter is:

$object = $objectService->createFromArray(
    $data,
    [], // $defaults — no schema-level defaults required for labels
);

This is informational only — not a blocker.


[INFO] Commit iteration numbering gap

Commit history shows fix iteration 1fix iteration 3fix iteration 4 (no fix iteration 2). The commit message for iteration 4 acknowledges and documents this gap. Noted for audit trail completeness — no code impact.

Security Review — Clyde Barcode (Hydra Security Reviewer)

PR: #99 — feat: add Label CRUD endpoints (#97)
Date: 2026-04-06

  • appinfo/routes.php (3 routes added)
  • tests/unit/Controller/LabelControllerTest.php (new)
  • tests/unit/Service/LabelServiceTest.php (new)

Findings

SEC-INFO-001 — No maximum length validation on title field

Severity: INFO
Location: lib/Controller/LabelController.php:127

The title field is validated for presence (empty()) but not for maximum length. An authenticated admin could submit an arbitrarily long string. OpenRegister may impose storage limits downstream, but this is not enforced at the API boundary.

Recommendation: Add a length guard before calling the service, e.g.:

if (mb_strlen($title) > 255) {
    return new JSONResponse(
        ['error' => 'The "title" field must not exceed 255 characters.'],
        Http::STATUS_BAD_REQUEST
    );
}

Positive Observations

  • Authorization: create() and destroy() both gate on isCurrentUserAdmin() before any data access — correct pattern for a Nextcloud app using IGroupManager.
  • UUID validation: destroy() validates the path parameter against a strict UUID regex (/^[0-9a-f]{8}-...-[0-9a-f]{12}$/i) before passing it to the service — prevents path traversal and injection.
  • Hex color validation: Strict regex (/^#[0-9A-Fa-f]{6}([0-9A-Fa-f]{2})?$/) accepts only valid 6- or 8-digit hex codes — no CSS injection risk.
  • Error information leakage: 500 responses return a generic message (An internal error occurred); exception details go only to the server log — correct.
  • CSRF: No @NoCSRFRequired annotation on mutating endpoints; Nextcloud framework CSRF protection applies by default.
  • Input sanitisation: All user input flows through Nextcloud's IRequest::getParam() and is validated before use — no raw $_POST/$_GET access.
  • No secrets or credentials introduced in any file.

Overall Assessment

PASS — no blocking security issues. One informational finding (SEC-INFO-001) is noted but does not block merge.

But the OAS spec for DELETE /api/labels/{id} only documents responses 204, 403, 404, and 500 — the 400 response is absent. API clients and generated SDK code relying on the spec contract will not know to handle this response.

Fix: Add a 400 entry under DELETE /api/labels/{id} responses:

'400':
  description: Invalid UUID format supplied as label ID.
  content:
    application/json:
      schema:
        $ref: '#/components/schemas/Error'

This is the only gap between the spec and the implementation.

[SUGGESTION] Non-standard @spec PHPDoc tag on every method

lib/Controller/LabelController.php and lib/Service/LabelService.php — all method docblocks

Every method carries:

@spec openspec/changes/label-crud/tasks.md#task-1

This was flagged in an earlier review round. The tag is not a recognised PHPDoc annotation; static analysers (Psalm, PHPStan) would warn about it, but the current CI configuration suppresses those warnings. No existing file in the repo uses this tag (see SettingsController.php, SettingsService.php).

If spec traceability is desired, a standard inline comment above each method is preferred:

// spec: openspec/changes/label-crud/tasks.md#task-1

This is informational — not a blocker.

[SUGGESTION] 204 No Content response passes an empty array body

lib/Controller/LabelController.php — line 171

return new JSONResponse(data: [], statusCode: Http::STATUS_NO_CONTENT);

RFC 7230 §3.3 states that a 204 response MUST NOT include a message body. Nextcloud's JSONResponse will serialize [] as an empty JSON array and set it as the response body; whether it is actually transmitted depends on the web server / PHP SAPI stripping it. The OAS spec for this endpoint correctly documents description: Label deleted successfully. No response body.

HTTP clients are required to ignore any body on a 204 response, so this is low risk in practice. Consider using new DataResponse(null, Http::STATUS_NO_CONTENT) (which Nextcloud treats as a truly empty body) to be strictly spec-compliant.

This is informational — not a blocker.

[SUGGESTION] Missing 500-error test cases for create() and destroy()

tests/unit/Controller/LabelControllerTest.php

The test suite covers the happy path and all validation failure paths for create() and destroy(). It also covers the 500 error path for index() (testIndexReturnsErrorWhenServiceFails). However, there are no equivalent tests verifying that create() and destroy() return HTTP 500 when LabelService throws a RuntimeException.

Both methods have matching catch (\RuntimeException $e) blocks with the same generic-error response pattern, so the behaviour is implemented — it just has no test coverage.

Consider adding:

  • testCreateReturnsInternalErrorWhenServiceFails
  • testDestroyReturnsInternalErrorWhenServiceFails

This is informational — not a blocker.
