zvx 5d64a8f70d feat(2-G): USGS NWIS adapter (OGC API) + CENTRAL_HYDRO stream ... NASA WaterData OGC API v0 (latest-continuous collection) — polls configured parameter codes within an operator-set bbox and publishes on the new CENTRAL_HYDRO stream. - Subject: central.hydro.<parameter_code>.<agency>.<bare_site_no> (e.g. central.hydro.00060.usgs.05420500). The agency/site decomposition lives in a single _subject_tokens_for_id helper. - Default parameter codes: 00060 (discharge), 00065 (gage height), 00010 (water temperature). Operator-tunable; single SoT in _DEFAULT_PARAMETER_CODES — no parallel literals. - Composite dedup: nwis:<monitoring_location_id>:<param>:<time_iso>. Prefix kept in dedup key for cross-agency uniqueness. - Pagination: follows OGC 'rel=next' link until absent (cursor-based). - Region bbox is REQUIRED in practice; adapter logs WARN at startup if region is None (does not refuse to start). - New stream CENTRAL_HYDRO added to streams.py registry (one line). Retention mirrors CENTRAL_DISASTER (7 days, 1 GiB). - No removal pattern in v1 — sites are static; missing data is the signal. Upstream divergences from the original spec brief, caught by pre-build curl: - Collection is 'latest-continuous', not 'instantaneous-values'. - Site filter param is 'monitoring_location_id' (singular), not 'monitoring_locations_id' (plural). - Site identifier requires agency prefix in queries (USGS-NNNNN). - feature.id is a per-record UUID, not stable; dedup uses joint key. Ships disabled; operator enables via GUI after setting a bbox.		2026-05-19 16:50:21 +00:00
