- Add k8s/ manifests (StatefulSet, kustomize, PDB, ServiceMonitor) + docs/runbooks/kubernetes.md - Add tidal-server/src/openapi.rs (utoipa OpenAPI spec) and wire into router - Add docs/guides/ (build-a-feed-app, embeddings, server-deployment) + foryou_feed example - Consolidate tidal/docker/ into root docker/ (single canonical home) - Update API.md, QUICKSTART.md, README.md, CLAUDE.md, check-docs.sh accordingly

tidalDB Engineering Docs
The engineering documentation home. Top-level product docs (VISION, USE_CASES, SEQUENCE, ARCHITECTURE, API, QUICKSTART, CODING_GUIDELINES, thoughts) live at the repository root; everything below is the deeper engineering record.
This and the repo root are the two canonical doc homes. There is intentionally no per-crate doc mirror (no
tidal/docs/). Edit the canonical file, never a copy.
Component specs — specs/
The authoritative component specifications (status: Implemented, M0–M8).

- Server deployment — running the
tidal-serverHTTP service: config, auth, the served OpenAPI spec, Docker - Ranking-profile reference: ai-lookup/services/ranking-profiles.md — all 25 built-in profiles
