feat(rest-api): add machine label value endpoints - #5533
Conversation
Summary by CodeRabbit
WalkthroughThe API now exposes sorted, distinct label values for ExpectedMachine and Machine resources. Handlers validate fields, authenticate users, enforce organization and site access, and query filtered DAO results. ChangesLabel value enumeration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to This PR adds machine-label discovery endpoints with no actionable merge-blocking risk remaining after normal checks and review. Sequence Diagram(s)sequenceDiagram

98-110: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtend the table with the negative authorization and
siteIdcases.The table covers only success paths. Three behaviors described by the PR remain untested:
- A Tenant Admin whose
TenantAccountConfig.TargetedInstanceCreationisfalsemust not see values from the linked Site.- The optional
siteIdquery filter must restrict results.- An invalid
fieldmust produce 400.The first case guards the authorization branch, so it carries the most value. Also note that
statusCodeis currently alwayshttp.StatusOK, and lines 123-125 unconditionally decodeAPILabelValues; add per-case expected values before you add non-200 cases.🤖 Prompt for AI Agents

Adds dedicated discovery endpoints for clients that need the available values of a Machine or Expected Machine label without downloading and scanning every resource:
GET /nico/expected-machine/label/{key}/valuesGET /nico/machine/label/{key}/valuesBoth endpoints return sorted, unique values, optionally scoped by
siteId. Provider and privileged Tenant visibility matches the corresponding list APIs, so Tenant callers only see values from Sites whereTargetedInstanceCreationis effective.The query uses a parameterized JSONB path expression. Label keys containing reserved path characters remain supported when percent-encoded, for example
nvidia.com%2Ffailure-domain.Related issues
