Ragnor Comerford 0976cbebc5 tests: pin /ingest admission gate + 429 Retry-After (red) ... Per AGENTS.md rule 8, this commit lands the failing regression test ahead of the fix. Currently fails on f925ad1 with 8/8 statuses returning 200 because /ingest does not call WorkloadController::try_admit. The test pins: - /ingest is gated on per-actor admission control (returns 429 when the cap is exceeded). - 429 responses carry the structured `code: too_many_requests` error body so clients can distinguish them from generic conflicts. - 429 responses include a `Retry-After` header so clients can implement bounded backoff. The doc claim at api.rs:343 and lib.rs:344 was that this header exists; the IntoResponse impl currently emits no headers. Two follow-up commits will turn this green: 1. Wire WorkloadController::try_admit on /ingest and the four other mutating handlers (Block 2.1). 2. Emit the Retry-After header on 429/503 responses (Block 2.2). The test uses #[serial] + EnvGuard to override OMNIGRAPH_PER_ACTOR_INFLIGHT_MAX=1 without racing parallel tests, then spawns 8 concurrent /ingest tasks aligned at a tokio::sync::Barrier so multiple tasks reach try_admit close in time. With cap=1, at least one must be rejected. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-08 16:57:01 +02:00
