"""HTTP monitoring tables (relocated from the former http plugin)

This revision originally lived in plugins/http/migrations. The http plugin has
been folded into core (unified Monitor entity), so its one migration is moved
here UNCHANGED — same revision id + "http" branch label — purely so the
revision stays resolvable in existing databases that already stamped it. The
0022_unify_monitors merge revision then absorbs this branch and drops these
tables after migrating their data into `monitor_results`.

Revision ID: http_001_initial
Revises: (none — branch off core via depends_on)
Create Date: 2026-03-22
