BrainService::http() was building a PendingRequest with no auth
header, so when Qdrant has auth enabled (the production lthn.sh
deploy does) every upsert/lookup returned 401. The circuit breaker
logged the 401 via Cache::store('file'), which was the red-herring
cache-write error chased in the first #97 iteration.
Changes:
- BrainService loads + trims a Qdrant api key from
config('brain.qdrant.api_key') in the constructor.
- New qdrantHttp() helper returns a PendingRequest with the
api-key header when the key is non-empty, or the plain client
otherwise. Ollama + Elasticsearch call sites still use http()
(separate auth shapes).
- php/config.php adds a brain.qdrant.api_key entry reading
env('BRAIN_QDRANT_API_KEY').
- Good/Bad/Ugly Pest tests cover: configured key → header sent,
unset → header absent, empty-string → header absent.
