The stats page could only say how many alerts fired. It now answers when
one alert fires, how often, and how fast it is picked up and fixed: each
row of the top-alerts list opens /stats/alert/{name}, with a timeline,
by-hour and by-weekday charts, time-to-resolve per occurrence and a table
of every occurrence linking to its incident. The overview gains a
weekday-by-hour heatmap and a few derived observations.
An occurrence is an incident, not an alert row. Alert rows are reused per
fingerprint and mutated in place, so they carry no history; incidents are
the only record of each time something fired and was answered. That means
/api/stats/alerts/top now counts incidents opened (filtered on
triggered_at) so the list and the drilldown agree. The response keeps name
and count and only adds fields, so existing clients keep working, but the
counts can differ from before.
No migration: the lookups use incidents_signature_idx. Label breakdown,
team and severity filters and period-over-period deltas from the design
draft are left for later.

Users get a notification_channels table (replacing users.ntfy_topic); pages fan
out to every enabled channel through a notify.Provider registry, with ntfy as
the first provider. Fallbacks are typed {type, address}. Schema edited in place:
existing databases must be recreated.

The README was 1,240 lines of reference material and still described a
SQLite quick start. It is now a short tour (highlights, screenshots of the
web UI, an accurate quick start against Postgres), and each topic has its
own page under docs/ with an index: deployment, configuration, Alertmanager,
incidents, notifications, escalation, dead man's switches, single sign-on,
web UI, API and development. SERVICE-ACCOUNTS.md is rewritten from a
proposal into a reference, and TEAM-LOOKUP.md is gone with the endpoint it
described. The "Upgrading to ..." sections for an unreleased product are
dropped.
