📝 WalkthroughWalkthroughThe event-ledger API injects build metadata and exposes it through an unauthenticated ChangesEvent ledger version information
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to The PR adds an unauthenticated GET /info endpoint and stamps build metadata; supplied checks show the endpoint and health route working. Remaining follow-up is limited to test-context cleanup and explicit HEAD/OPTIONS verification, with no demonstrated merge-blocking defect. Sequence Diagram(s)sequenceDiagram

golibversion.Version, and golibversion.GitHash assignments to capture their
existing values before overriding them, then restore those saved values in
t.Cleanup instead of clearing the globals.
In `@src/control-plane-services/event-ledger/cmd/api/startup/run_service.go`:
- Around line 57-59: Remove the private tracker identifier from the comment
describing registerUnauthenticatedRoutes, while preserving the explanation of
the /health and /info routes.
- Around line 60-63: Update registerUnauthenticatedRoutes so the /info route
remains unauthenticated while applying the established otelmux tracing and
logging.LoggerMiddleware request middleware used by authenticated routes.
Preserve the existing golibversion.Handler handler and structured logging,
tracing, and RED metrics behavior.

- Around line 49-50: Update the `/info` route tests around
registerUnauthenticatedRoutes to inject middleware that records invocation or
adds a distinctive response header, then assert a GET request to `/info`
observes that behavior. Cover both existing tests that currently use a no-op
infoMiddleware, while preserving their other assertions.

Go httptest.NewRequestWithContext introduced Go version noctx golangci-lint
💡 Result:
The function httptest.NewRequestWithContext was introduced in Go 1.23.0 [1][2]. Regarding golangci-lint, the noctx linter added detection for httptest.NewRequestWithContext in its update from version 0.4.0 to 0.5.0 [3]. This linter is designed to identify instances where functions that support or require context.Context are called without providing one, encouraging the use of context-aware functions for better cancellation and timeout management [4][5].

Use an explicit request context.
Replace both httptest.NewRequest calls in this test with httptest.NewRequestWithContext and pass the test context. The module targets Go 1.26.1, so this API is available.

TL;DR
Adds
GET /infoto the event-ledger service, so DGXC Ops and QA can identify the exact build deployed to a cluster.Additional Details
GET /inforeturns{"service":"nvcf-event-ledger","version":"<semver>","commit":"<full sha>"}as JSON, and non-GET methods get 405 withAllow: GET. It registers alongside/healthon the base router before auth middleware, so it is reachable unauthenticated for build-version discovery, via a smallregisterUnauthenticatedRouteshelper so the wiring is unit-testable without full DB/config fixtures. Version and commit are stamped into the go-lib version package through Bazel x_defs (STABLE_VERSION,STABLE_GIT_COMMIT_FULL), the same pattern the other monorepo services use. The go-lib pin is bumped to the commit that addspkg/version.Testing
