fix(event-ledger): route JWT auth away from the API key evaluator#1074shelleyshen-0 wants to merge 6 commits into
Conversation
The policy provider funnelled every credential to the API key policy evaluator, whose contract requires an opaque API key. JWT-bearing callers were therefore rejected, and because the per-route scope wrappers were inert under that provider, token scopes were never enforced either. Split the two credentials into independent paths chosen by token shape. A JWT is verified against the configured JWKS and then authorized by the per-route scope check. An API key is forwarded to the evaluator as before and skips the scope check, since it carries no scopes. Requests the evaluator authorizes are marked so the scope wrapper lets them through. This removes the request-clone and no-op ResponseWriter workaround that let the JWT parser run inside the policy middleware, and passes the issuer and audience options through to the parser. Also accept the evaluator's actual verdict field name. It reports "allowed" while the response type only read "allow", so successful evaluations deserialized as denials. The existing client test hardcoded the wrong shape and masked this. Adds coverage for both paths, including scope enforcement driven through the real parser against a generated ES256 key and JWKS endpoint.

Could we hide the JWT/API-key difference behind one auth interface? DualAuthMiddleware makes the rest of the code aware of both credential types, when it should only need to know whether the request is authorized.
…iddleware Route registration previously had to build and wire two separate middlewares (a JWT parser and the policy client) and pass both into a dispatcher, so every call site needed to know both credential types exist. Fold the dispatch into a single NewAuthMiddleware, replacing the exported NewPolicyMiddleware/NewDualAuthMiddleware pair. run_service.go now makes one call and sees one mux.MiddlewareFunc; JWT verification, scope enforcement, and delegation to the policy client for API keys are all internal to it. Verified against a self-managed cluster: OpenBao JWT writes still succeed, JWT reads still 403 for missing scope, malformed/missing credentials still 401, and a minted API key still authorizes reads, in-cluster and through the gateway.

…Authorizer
The previous suite drove a hand-written testPolicyMiddleware that duplicated
the auth logic instead of calling newPolicyMiddleware/NewAuthMiddleware, so it
verified itself rather than production code. It also set JWT scopes as
[]string in test claims, while the real code type-asserts claims["scopes"] as
[]interface{} (what real JSON-decoded claims produce), so the scope-forwarding
path was never actually exercised.
Replace the fake harness with stubPolicyClient, which implements the real
policy.Authorizer interface, and drive every test through the production
middleware. Assert on the actual RuleRequest.Input built for the evaluator
(apiKey, subject, scopes, service) instead of a parallel test-only shape.
Merge auth_test.go's dispatch coverage in alongside it.
Also fixes BUILD.bazel, left listing dual_auth.go and dual_auth_test.go as
srcs after both were deleted in the prior commit.

Propagate TenantClaim to policy-provider JWT parsing.
When cfg.SelfManaged is true, the policy branch omits cfg.Auth.TenantClaim. NewParseJWTMiddleware then skips tenant context creation, and MaybeRequirePathTenant(true) allows requests without that context. A JWT can therefore access a different ncaId or namespace.
Set opts.TenantClaim = cfg.Auth.TenantClaim and add a non-default tenant-claim regression test.

@borao same with this. Does this need to be added to policy path?
… provider" This reverts commit 0207704. Self-managed's OpenBao-issued tokens always carry exp, so this had no effect there. Managed's actual token issuer is unverified from this repo, and enabling a previously-off validation check can only reject tokens that currently pass, so this needs confirmation against managed's real JWTs before it ships.

@borao refactored. Please review again. Thanks. |

TL;DR
JWTs were sent to the API-key evaluator, which only accepts an API key, so SIS/NVCA writes always failed. Route JWTs to local verification and scope checking instead. Also fixes the evaluator's verdict field name so valid API keys stopped reading as denials.
Additional Details
Two defects broke every request in self-managed:
apiKey-only contract, producing a 400 read as 401.allow; the evaluator returnsallowed.Scope enforcement was also inert for this provider. Now: JWTs are verified locally and scope-checked; API keys still go to the evaluator, unchanged. Managed deployments unaffected.
