Schema rebuild for the model collapse described in
design/v4-sources-redesign.html. Three nouns now stand on their
own:
* schedules — slim. Only cron + enabled + host_id. Fat-schedule
shape (paths/excludes/tags/retention/manual/kind/options/hooks)
is dropped wholesale. Schedule data wiped — by design (smoke env
was nuked before this ran; fresh installs have nothing to lose).
* source_groups — name + includes + excludes + retention_policy +
retry policy + cached conflict_dimension. Group name doubles as
the snapshot tag so retention can target it cleanly. UNIQUE
(host_id, name) enforces tag unambiguity.
* schedule_source_groups — N:M junction. One schedule can fire N
groups per tick; one group can be referenced by N schedules.
* host_repo_maintenance — 1:1 with hosts. Default cadences:
forget daily 03:00, prune weekly Sun 04:00, check monthly 1st
05:00 with --read-data-subset 5%. Operator can edit on Repo tab.
* pending_runs — offline-retry queue. Server-side ticker dispatches
due rows; bounded by source_groups.retry_max + retry_backoff_seconds.
Plus:
* hosts.bandwidth_up_kbps / .bandwidth_down_kbps — host-wide caps.
* hosts.repo_initialised_at — DROPPED. Auto-init on enrol makes
it derivable from the latest init job; the Init-repo button goes
too (failure surfaces via job history banner).
Note on FK safety: smoke env was wiped before migration ran, so
DROP TABLE schedules cascades to nothing. Fresh installs apply
0001-0007 then immediately 0008 — same story (no schedule rows
to lose). For an upgrade path on a populated DB, this migration
would need a data-preserving variant; not needed today.
Tests fail to compile/run after this — expected. The Go side
(store types, CRUD, REST handlers, agent runner, UI templates)
gets rebuilt in subsequent phases. tasks.md will track P2 redesign
progress.
