{“what”:“Auto-incrementing integer that uniquely identifies a signal.”,“why”:“Without it, rows cannot be referenced uniquely for updates or joins.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.748677894+00:00”} |
||||
| profile_id | int4 | 10 | √ | null |
|
|
{“what”:“Integer referencing the profile associated with this signal; null when no profile is linked.”,“why”:“Without it, it is unknown which profile a signal belongs to, breaking profile-scoped queries.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.772862895+00:00”} |
||||
| contact_id | int4 | 10 | √ | null |
|
|
{“what”:“Integer referencing the contact associated with this signal; null when no contact is linked.”,“why”:“Without it, signals cannot be linked to a contact, making contact-specific signal history impossible.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.791676428+00:00”} |
||||
| signal_type_slug | text | 2147483647 | null |
|
|
{“what”:“Text slug that classifies the signal into a known type.”,“why”:“Without it, signal types are indistinguishable, so filtering or aggregating by type is impossible.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.803644319+00:00”} |
|||||
| raw_text | text | 2147483647 | null |
|
|
{“what”:“Unprocessed text payload of the signal as received.”,“why”:“Without it, the original content is lost, preventing later parsing or re-analysis.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.829651668+00:00”} |
|||||
| intensity | float4 | 8,8 | √ | null |
|
|
{“what”:“Numeric intensity value of the signal, as a real number; null if not measured.”,“why”:“Without it, the strength or magnitude of the signal is unknown, affecting prioritization or scoring.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.872770159+00:00”} |
||||
| source_url | text | 2147483647 | √ | null |
|
|
{“what”:“URL where the signal originated or was observed.”,“why”:“Without it, the origin of the signal cannot be traced for verification or attribution.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.912031794+00:00”} |
||||
| observed_at | timestamptz | 35,6 | now() |
|
|
{“what”:“Timestamp (with time zone) when the signal was observed; defaults to current time.”,“why”:“Without it, the timing of the signal is unknown, breaking time-based analysis and ordering.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.943566623+00:00”} |
|||||
| expires_at | timestamptz | 35,6 | √ | null |
|
|
{“what”:“Timestamp (with time zone) after which the signal is considered expired; null if never expires.”,“why”:“Without it, it is unknown when a signal becomes stale, so expiry-based filtering or cleanup is impossible.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-23T04:16:52.980322425+00:00”} |
