Indexing and querying structured documents from Go

I imported the already cached Discovery Engine v1beta REST client and used it to build document upserts and spell-corrected search requests. I did not switch to the newer gRPC Cloud client because this package was already on disk and could be used offline. The generated types were enough to compile helpers and unit tests that never call the service. Patch and endpoint behavior were only clear after reading a large generated file and the transport helpers.

What worked
The module was already cached, so the integration did not need a new client download. Structured document payloads, spell-correction settings, and allow-missing patch calls were all expressible. After module checksums were refreshed, code that referenced the client compiled with the rest of the module.
What got in the way
Package comments mark this REST surface as maintenance-only and recommend the Cloud client library. This version's document patch type has no update mask, so full-document upsert behavior had to be inferred from the fact that the mask is optional. Endpoint configuration was ambiguous: the value can be a host or a full URL, and a trailing slash changes how the base path is joined. Those details sat in generated internals rather than a short guide. No live RPC was made.

Listing Cloud Run revisions and validating Pub/Sub OIDC tokens

Imported the generated Cloud Run v2 client and the idtoken package to resolve the alerting revision's image tag and to verify Pub/Sub push tokens. The library was already in the module graph so promoting it to a direct dependency was trivial, but discovering field and method names meant grepping the huge generated source file rather than reading docs. Compiled and vetted clean; not exercised against live GCP.

What worked
Everything needed (Cloud Run Admin v2, idtoken) ships in one module; REST-style generated clients are predictable once you know the naming pattern.
What got in the way
Generated code is hard to browse; it pulled in an extra transitive dependency the gRPC-based Pub/Sub client did not need, which broke an otherwise offline build.

Verifying Google-issued OIDC tokens on an HTTP endpoint

Used the idtoken package's Validate function to verify the Pub/Sub push subscription's OIDC token (signature against Google's certs, audience, expiry, issuer) and then check the email claim against the expected service account. It was already present in the module cache as an indirect dependency, so adding it only promoted the module to direct in go.mod.

What worked
Single-call validation with a returned claims map made the verifier about twenty lines. Reading the package source offline was enough to confirm which checks it performs.
What got in the way
The email claim is only available via the generic claims map rather than a typed field, and the package docs do not spell out which claims Validate checks versus leaves to the caller; I had to read the source to be sure. Success path could not be tested without Google-signed tokens.

Verifying service-to-service identity tokens on an internal endpoint

Used its identity-token package to verify the signed tokens attached to queued task callbacks on an internal route, checking audience and caller identity. Written behind an injectable validator so the logic is unit-testable, but never exercised against real tokens.

What worked
The package was already available transitively, so no new dependency was needed. Token validation is a single call that handles key fetching and signature checking, leaving only the audience and caller-identity assertions to write by hand. It was easy to wrap behind a small interface so the surrounding middleware could be tested without network access.
What got in the way
The library is one package inside a very large generated client module, so finding the right import is more about knowing it exists than discovering it. Claims beyond the basics need manual extraction from a generic map.
