Stands up the shadow-ingest substrate without touching production:
- schema.go: faithful replica of db_async.init_db_async (idempotent DDL),
run only when an instance OWNS its DB (READ_ONLY=false). Fixes for a fresh DB:
spawn_events has no sole-id PK (so it can be a hypertable), telemetry_events
compression is enabled before its policy, and the portal unique index uses
ROUND(..,1) to match main.py's ON CONFLICT. 35/35 statements OK.
- store.go: read-only transaction enforcement is now conditional (on for
production read parity, off for ingest).
- main.go: READ_ONLY + SHADOW_INGEST_WS config; schema init on boot when owning
the DB.
- compose override: a SEPARATE TimescaleDB `dereth-go-db` (isolated volume,
127.0.0.1:5434) and a `dereth-tracker-go-shadow` instance (image reused via
dereth-tracker-go:local) that owns it. Production DB never written.
Verified: dereth_go has all 13 tables; telemetry_events + spawn_events are
hypertables; the read-side instance still serves production read-only.
