Add a SPEAKER ROLES section to the GPT-4o-mini prompt teaching it to
distinguish dispatch voice (names a unit then gives assignment + address)
from unit voice (opens with own callsign + brief status). Applied to
location attribution (dispatch-provided address beats unit position report)
and unit extraction (dispatched units vs. acknowledging units). No extra
API calls — purely prompt-level reasoning on the existing transcript.
- Geocoding: reject GEOMETRIC_CENTER/APPROXIMATE results — vague location strings
(regions, city centroids) were resolving to node-area coords and creating false
proximity matches that merged unrelated incidents
- Thin path: on dispatch channels with multiple active incidents, skip attachment
rather than guessing — "10-4" with 3 active incidents is genuinely ambiguous
- Short transcripts (≤5 words) now write skip_reason="transcript_too_short" to
the call doc, matching garbage transcript behavior
- upload.py no-scenes fallback now checks skip_reason before running correlation —
flagged calls (garbage, too short) no longer attach via thin path
- Update Server README to reflect current project purpose, goals, and pipeline
