Phase 2 of the SFM integration. Adds a "SFM Events" section to the
seismograph unit detail page (/unit/{id}). Every event SFM has for the
serial is shown, with each event annotated by which project/location
assignment window it falls into. Events outside every assignment window
get the "⚠ Unattributed" badge plus a "<N>d before/after <nearest location>"
hint — that's the operator's signal that backdating an assignment (Phase 1
edit-pencil) will absorb the orphan events.
Backend:
- backend/services/sfm_events.py: new events_for_unit() helper. Fetches
all events for the serial via SFM /db/events (one call, ceiling 5000),
loads every UnitAssignment for the unit + resolves MonitoringLocation +
Project names, then annotates each event with attribution or
nearest_assignment (signed delta_days). Bucket filter: all /
attributed / unattributed. Stats always reflect the full event set so
the "Unattributed" KPI tile is meaningful regardless of which bucket
is being viewed.
- backend/routers/units.py: new GET /api/units/{unit_id}/events with
bucket / date-range / false_trigger / limit query params. 404s on
unknown unit_id; returns an empty payload for non-seismograph
device_types so the page can render the section conditionally.
Frontend (templates/unit_detail.html):
- New "SFM Events" section between "Deployment History" and "Timeline",
styled to match the existing card pattern (border-t divider, same
heading weight).
- Hidden by default; revealed only when currentUnit.device_type ===
'seismograph' after the unit data loads.
- Four KPI tiles: Total Events / Unattributed (highlighted amber when
> 0) / Peak PVS / Last Event.
- Filters: Bucket (all|attributed|unattributed), From/To, False
Triggers, Limit, + Refresh.
- Event table with Attribution column. Attributed rows link to the
project/location detail page; unattributed rows are tinted amber
and show "<N>d before/after <nearest location>" with a link to the
nearest location.
- Empty-state copy varies by bucket: e.g. unattributed-with-zero shows
"✅ All events for this unit are attributed to a project/location".
Verified end-to-end against BE11529 (81 events total, 24 attributed,
57 unattributed — all 57 unattributed events emitted within hours of
the assignment start, which means backdating the assignment by a day
would attribute every one of them).
