"""Curated Windows event catalog: id -> human title and severity.
|
|
|
|
Single server-side source of truth shared by the recent-events asset panel and
|
|
the stability dashboard card, so a 4625 reads as "Failed logon (warning)" in
|
|
both places without either restating the mapping. The set of IDs here MUST stay
|
|
in step with CURATED_EVENT_IDS in plugin.py; a test asserts they match.
|
|
|
|
Severity vocabulary matches the dashboard card renderer: 'critical', 'warning',
|
|
'info'. The IDs marked critical are the ones an operator/tech should act on
|
|
without being asked - unexpected shutdown, crash, filesystem corruption, SCM
|
|
timeout. Logon activity is informational history unless it is a failure.
