From 7f2e34f5b364f114ead4bef3d7930aad04b70f3b Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Wed, 8 Jul 2026 22:15:59 -0700 Subject: [PATCH] test(FN-7690): reconcile anthropic-compatible apiType assertions + de-slow retry test FN-7690 changed resolveApiType() to return the registered pi-ai key "anthropic-messages" for anthropic-compatible providers (the bare "anthropic" key is never registered and throws at stream time), but left behind a stale JSDoc and a stale test expectation: - custom-provider-registry.ts: update the FN-7689 buildCustomProviderModels comment that still described the anthropic/anthropic-messages drift as unresolved. - provider-registration.test.ts: assert config.api === "anthropic-messages" (was still asserting the pre-fix "anthropic"). Also de-slow a retry-exhaustion test: the describe uses fake timers with shouldAdvanceTime, so awaiting a 3-retry backoff (1s+5s+15s) burned ~21s of real wall time. Drive the backoff with advanceTimersByTimeAsync instead (Standing Rule: prefer fake timers over real time waits).
