feat: adopt ai-kit's tryChain + createHealthTracker; add /api/health - #26
Merged
Conversation
hirnli has already been silently taken down once by a single retired Groq model id -- every route and script here called ONE pinned model, once, with nothing between that and total failure. This closes that gap the same way botsmann's did this session. - scripts/lib/groq-client.ts: callGroq now walks ai-kit's fallback chain for Groq via tryChain when the caller leaves the model unspecified, instead of calling one hardcoded id. GROQ_MODELS' alias table is now derived FROM that chain rather than hardcoding the same ids a second time. An explicit model/alias is still honoured as-is and alone, unchanged. - src/app/api/ai/gesuch-section/route.ts: this route hand-rolled its OWN separate Groq fetch, with its own hardcoded model id -- a second copy of exactly what groq-client.ts already did, despite that file's own docstring saying it was "extracted from" this route. Now calls callGroq directly; ~50 lines of duplicated fetch/error-handling code deleted. - src/lib/llm-health.ts + src/app/api/health/route.ts (both new): hirnli had no health endpoint at all. Records success/failure around the gesuch-section route via ai-kit's createHealthTracker, exposed at /api/health (liveness) and /api/health?strict=1 (readiness -- 503 only when the LLM chain itself is down, never on a restart-proof problem). ai-kit bumped to v0.5.0. Full verify green: lint, lint:umlauts, typecheck, 889 tests (17 new), production build. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Summary
scripts/lib/groq-client.ts:callGroqnow walksai-kit's fallback chain for Groq (tryChain) when no explicit model is given, instead of calling one pinned id once.GROQ_MODELS' alias table is now derived from that chain rather than hardcoding the same ids a second time.src/app/api/ai/gesuch-section/route.ts: deleted its own separate hand-rolled Groq fetch (a second copy of exactly whatgroq-client.tsalready did — its own docstring says it was "extracted from" this route, but the route was never switched over) and now callscallGroqdirectly.src/lib/llm-health.ts(wrapsai-kit'screateHealthTracker) +src/app/api/health/route.ts— hirnli had no health endpoint at all./api/healthfor liveness,/api/health?strict=1for readiness (503 only when the LLM chain is actually down).ai-kitbumped to v0.5.0.This closes the same gap this session already fixed in botsmann: hirnli was flagged by a fleet-wide AI-tooling audit as having zero shared-package adoption with no stated reason to skip, and the smallest hand-rolled surface in the fleet.
