Summary

Audit of feature flags and env toggles in the API. Only one met the bar for removal.

Removed

  • skipAuthCheck env var (api/server.go). When set to true, it turned off isAuthorizedRequest entirely, and production code read it from the environment. Nothing in this repo, compose, or k8s sets it. Every test that needs it sets app.skipAuthCheck = true on the struct, which still works. Added in elasticsearch #151 (2025-06) and never used through the env since. This cuts a dead toggle and an auth bypass at the same time.

Audited and kept (needs a decision from someone with prod access)

  • commsMessagePush: defaults on since [API-292] Adds back comms websocket support #349 (2025-09). The env override only turns it off. server_test.go depends on it to keep the websocket manager and pg-notify listeners out of the shared test app, so it works as a test seam. I couldn't confirm prod doesn't set commsMessagePush=false; if it doesn't, the env parse can go, but the struct field should stay for tests.
  • coreBlockStreamEnabled: defaults off and arrived in feat(api): consume blocks via gRPC StreamBlocks (flagged, default off) #941 (2026-06, ~5 months ago). I couldn't see the prod env (no RBAC on deployments/configmaps). If prod has it on, inline it; if it was never turned on, consider deleting the gRPC stream path.
  • newChainQueueEnabled / newChainFlushEnabled / newChainInsecureSkipVerify / etlStartingBlockHeight / etlEndingBlockHeight / PlayRoutingHosts: the genesis migration is still in progress (see cmd/genesis-writer/ROLLOUT.md). Not stale yet; remove them at cutover.

Test plan

  • go build ./... and go vet ./api/
  • go test ./api/... (couldn't run locally because Docker/test DB was down; CI covers it)

The auth-middleware bypass was readable from the skipAuthCheck env var in
production code. Nothing deploys it; tests set app.skipAuthCheck directly.

#1078 removed the last `strconv` use in `api/server.go`, so `go build`
and the Docker image build on main fail (run for 570f3d3). Prod is still
on the 5c7465d image; nothing new deploys until this lands.

`go build ./...` and `go vet ./api/` pass.
