P2-04.5: kill host.default_paths in favour of manual schedules
Two independent path lists for "what does this host back up?" was
a real divergence footgun — operator types one set at Add-host time
and a different set into a schedule, both end up in the same repo,
the snapshot history looks fine until restore. Resolution: drop
host.default_paths entirely; add a `manual` flag on schedules.
A manual schedule has paths/excludes/tags/retention like any other
but no cron — it fires only via per-schedule Run-now. Single source
of truth for what gets backed up.
Schema (migration 0007):
* schedules.manual INTEGER NOT NULL DEFAULT 0.
* For every host with non-empty default_paths, seed a manual
schedule with those paths and bump host_schedule_version.
* ALTER TABLE hosts DROP COLUMN default_paths.
* ALTER TABLE enrollment_tokens RENAME COLUMN default_paths
TO initial_paths.
Original draft of this migration rebuilt hosts via the
create-new + drop-old + rename-new pattern. With foreign_keys=ON
(set in the connection DSN), DROP TABLE on the parent fired
ON DELETE CASCADE on every child of hosts(id) — schedules /
jobs / snapshots / host_credentials all wiped on the smoke env
when I tried it. SQLite 3.35+ supports column-level ALTERs
directly, so we skip the rebuild dance and avoid the cascade
trap. Six lines of SQL instead of sixty, no FK risk.
Run-now rewiring:
* New `dispatchScheduleNow(hostID, scheduleID, conn?)` helper
unifies the agent-driven path (cron fire → schedule.fire →
OnScheduleFire callback) and the UI-driven path (operator
clicks Run-now on a schedule row). Conn arg is optional; nil
falls back to Hub.Send.
* New POST /hosts/{id}/schedules/{sid}/run endpoint — per-row
Run-now button on the schedules list.
* Dashboard's per-host Run-now (handleUIRunBackup) now picks the
host's only enabled manual schedule, falls back to the only
enabled schedule, else returns "pick one in Schedules tab".
Keeps one-click for the common case.
Agent:
* Scheduler skips manual schedules in cron build (silent — they're
a normal data shape, not an error).
* Wire Schedule struct gains Manual flag.
* Schedule.fire flow unchanged — the agent only ever fires
non-manual schedules anyway.
UI:
* Add-host form retitled "Initial schedule · manual" so the
operator knows the paths become an editable schedule under
the Schedules tab. Result page calls out the manual schedule
+ points at Host > Schedules.
* Schedule edit form: "Manual schedule" checkbox at the top of
the When section; toggling it hides/shows the cron field via
inline JS. Server-side validator skips the cron requirement
when manual=true.
* Schedule list shows a "manual" tag under the status pill and
renders the When column as "— run-now only —" for manual rows.
Each row gets a Run-now button when the schedule is enabled
and the host is online.
Tests + go test ./... green.

P2-02 (agent side) + P2-03: agent scheduler + schedule.fire dispatch
Closes the schedule reconciliation loop end-to-end.
* New `internal/agent/scheduler` package wraps robfig/cron/v3 with
the lifecycle the agent needs:
- Apply(ScheduleSetPayload, Sender) stops the prior cron (waiting
for in-flight entries to return), rebuilds from scratch, starts,
and emits schedule.ack with the version we just applied.
- Disabled entries skipped silently; bad cron exprs (which
shouldn't reach us — the server validates — but defensive)
log a warn and skip.
- On each cron tick the entry sends a new schedule.fire envelope
to the server with {schedule_id, scheduled_at}. The scheduler
itself never builds CommandRunPayloads — server is the source
of truth for jobs.
- tx is swapped on every Apply, so reconnect is handled
naturally: cron entries that fire against a dropped tx log
"no active connection" and skip the tick.
- Stop() is idempotent and waits for the cron's in-flight
workers via cron.Stop().Done().
* New wire message api.MsgScheduleFire + api.ScheduleFirePayload
for the agent → server "I just fired locally" RPC.
* Server-side dispatch (schedule_push.go: dispatchScheduledJob):
looks up the schedule by id, validates ownership + that it's
enabled, builds args from kind (paths for backup; other kinds
are still arg-less in Phase 2 and grow as those job kinds land
in P2-05..08), persists a jobs row with actor_kind=schedule +
scheduled_id, and writes command.run back on the same conn so
the agent runs through its existing dispatch path.
* store.CreateJob now writes scheduled_id. This column was in the
schema since 0001 but never populated — the original P1 path
only had operator-driven jobs, so actor_kind was always 'user'
and scheduled_id was always nil.
* cmd/agent/main.go integration: dispatcher gains a
*scheduler.Scheduler; the MsgScheduleSet case now hands the
payload to scheduler.Apply (in a goroutine so the WS read loop
keeps draining other messages).
* WS dispatcher gains OnScheduleFire alongside OnScheduleAck.
* Tests:
- scheduler unit tests (4): ack-on-apply, cron tick fires
schedule.fire envelope, disabled entries don't fire, replace-
prior-state stops the old cron.
- Server-side end-to-end: schedule.fire → command.run with the
right job_id / kind / args, plus jobs row with actor_kind=
"schedule" and scheduled_id linking back to the schedule.
Persistence of next-fire times across agent restarts is
deliberately deferred. A missed fire window during downtime
simply fires once on reconnect — that's the desirable behaviour
(the operator wants the missed backup to run, not be silently
skipped because we lost track of when it was due).

P2-02 (server side): schedule reconciliation push + ack handling
Server is now the source of truth for the agent's cron set.
* Helpers in schedule_push.go:
- loadScheduleSetPayload reads the host's schedules + canonical
version into the wire shape.
- pushScheduleSetOnConn writes directly to a just-handshaken conn
(avoids racing against Hub.Register on a brand-new connection).
- pushScheduleSetAsync is the post-CRUD flavour — no-op when the
host is offline (the next reconnect's on-hello path catches it
up, so a missed push is non-fatal).
- applyScheduleAck records what version the agent has confirmed.
* onAgentHello restructured: was returning early when the host had
no repo credentials, which made the schedule push unreachable for
fresh hosts. Split into pushRepoCredsOnHello (silent no-op on
ErrNotFound) + pushScheduleSetOnConn (always runs). Empty schedule
list is a valid push: tells the agent to drop stale cron entries.
* WS dispatcher gains an OnScheduleAck hook on HandlerDeps; the
http server wires it to applyScheduleAck. MsgScheduleAck moves
out of the "TODO(P2)" group into a real case that decodes the
payload and forwards to the callback.
* Schedule CRUD handlers each fire pushScheduleSetAsync after the
audit-log write so the agent picks up changes within seconds.
Tests cover:
- On-hello push of an already-created schedule, agent acks,
applied_schedule_version flips on the host row.
- Connect-then-CRUD: empty initial push (version 0), then a
follow-on push at version 1 after the operator creates a
schedule via REST.
Agent-side `schedule.set` handler (parse, replace local cron,
emit `schedule.ack`) is the remainder of P2-02 and lands with
P2-03's local scheduler.
