A metric registered with learn_normal() gets, for every resource reporting it, a usual hold (the 90th percentile across past days of each hour's p95) and a usual peak for each slot: - an hour of the day once 5 days of history exist; - an hour of the week once history reaches back 3 weeks, so weekly jobs are learned too. Each slot takes in the hours either side, so a job that runs a little late stays normal. One SQL statement relearns everything hourly into metric_norms, from the rollup plus the raw window not rolled up yet; norms_at() reads the slot a moment falls in. Nothing is registered yet: Traefik (#5741) and hosts (#5742) opt in. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""What a backup carries. Every table Steward defines is named here as kept
|
|
or left out, and tests/core/test_backup_contents.py fails on one that is
|
|
neither, so a new table is a decision someone makes in this file.
|
|
|
|
The operator's ruling (System 180 "Backup & Restore", 2026-10-12): a backup
|
|
carries configuration, the audit log and alert history. Metrics, check
|
|
results and the Docker, Traefik and UniFi history are left out: their tables
|
|
come back with their structure and no rows, and fill again as Steward runs.
|
|
|
|
A table that is in neither list (an external plugin's) is backed up whole:
|
|
a table nobody thought about is kept, never lost.
