Add an optional, off-by-default spam-detection feature that scores each message's spam likelihood at ingest, stores the score on the row, and lets the display layer hide likely-spam by default behind a "show potential spam" toggle. Nothing is ever dropped at ingest, so the threshold can be retuned without reprocessing. Scoring (collector/spam.py): windowed COUNT(*) over new (path_prefix, received_at) and (sender_normalized, received_at) indexes — joint path+sender signal plus a sender-name signal (trailing-digit suffix stripped so bob1/bob2 collapse to bob). When the path is short/zero-hop or absent, the name signal stands alone at full weight so local spam is still flaggable. A background sweep re-scores recent rows with hindsight to catch the leading edge of bursts. The collector logs each score (WARNING at/above the threshold). Display: the messages API gains include_spam and a master-switch-aware hide-filter; the SPA shows the toggle + a badge only when the feature is on. Config: FEATURE_SPAM_DETECTION is the single operator switch, bridged in Compose to the backend SPAM_DETECTION_ENABLED for collector + api (mirrors the FEATURE_PACKETS / RAW_PACKET_CAPTURE_ENABLED pattern). Both default off. Works on SQLite and Postgres: DB-agnostic queries, an Alembic batch migration for the three new columns + two indexes, and backend-aware collector test fixtures (lifted db_backend/db_url into the shared conftest). Also: move the meshcore-hub image pull_policy out of the base compose file. It lived in docker-compose.yml as pull_policy: daily and made `make up` pull the published image over a freshly built local one. Base is now policy-neutral (default missing); dev sets pull_policy: build on the hub services so it only ever uses local builds. Prod refreshes images via a manual `docker compose ... pull`.
