WalkthroughAdded configurable tenant enforcement for API requests. Configuration supports trusted system callers and required or optional tenant dimensions. Validation rejects invalid, conflicting, duplicate, and forbidden settings. Middleware resolves tenant identity, attaches tenant context, and returns RFC 9457 403 responses for invalid requests. The API server enables the middleware when configured. Added permission-denied errors and tests. Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to The PR adds tenant identity enforcement and related configuration, with the supplied checks covering the documented behavior; no actionable merge-blocking risk remains beyond normal checks and review.

- Around line 47-48: Update the apiServer lifecycle test to send the Serve
result to a buffered channel, and ensure cleanup checks the Stop error before
waiting for the serving goroutine’s result. Assert the expected Serve shutdown
outcome so lifecycle failures are surfaced and the goroutine is guaranteed to
exit.
In `@pkg/config/tenant.go`:
- Around line 36-40: Update the tenant configuration validation to reject HTTP
field names that are not valid tokens, including whitespace-containing or blank
names, for both SystemHeader and every TenantDimension.Header. Apply this
validation before accepting required dimensions or system-caller bypass
configuration, and add test cases covering invalid names such as X Tenant and a
whitespace-only value.
In `@pkg/tenant/middleware.go`:
- Around line 106-108: Update the rejected tenant identity handling in the
middleware to log the ServiceError at warning severity instead of Info, while
preserving the existing error construction and response flow.
- Line 70: Update the protected resource DAO read, write, delete, and list
operations to derive a tenancy predicate from tenant.FromContext(ctx), applying
it to every query; permit bypassing this predicate only for System callers.
Ensure tenant context is enforced consistently and add tests covering
cross-tenant access and modification attempts.

I wonder about the need of this file.
I mean we already have config.yaml.example, could we use that one for development purposes and avoid the risk of drifting?
There was a problem hiding this comment.
dev.yaml and config.yaml.example serve different purposes: dev.yaml is the runnable config so make run works out of the box; config.yaml.example is the reference template with all options documented. Keeping both means contributors don't have to maintain their own local config, since dev.yaml stays current as config evolves. Updating both together when adding config (as done here) keeps them in sync.

I find a bit confusing that we generate:
- the token at
/tmp - the
dev-jwks.jsonat./configs
There was a problem hiding this comment.
This is pre-existing behavior, not introduced here. The distinction: the token is ephemeral (regenerated on each make run, 8-hour expiry) so /tmp fits; the JWKS is referenced by dev.yaml and can persist across runs, so it lives in ./configs. Happy to revisit the locations in a follow-up if you feel strongly.
