ONE setting (window start W) drives every nightly leg at fixed, never-stored
offsets: DB dump at W, tier-2 at W+60m, off-box at W+105m (wrap-safe). Precedence
settings > controller.yaml db_dump_schedule > 02:30.
- scheduler.UpdateDaily: retime a daily job at runtime (no restart) via a per-job
buffered resched chan + a select case in runDailyJob.
- new pure package internal/backupwindow (LegTimes/GateWindow/EffectiveWindow).
- quiesce disk-tier window gate: scheduled cycles run only inside [W+2h,W+6h) with a
safety valve (age>cadence+24h runs regardless); manual TriggerNow never gated.
Backend.Due now also returns the backup age (from the agent's own /backup/due).
- backup page: Mentési időablak card (time input + derived leg/gate rows); POST
/backups/window validates -> saves -> UpdateDaily x3 -> flash.
Tests: 5 groups, all red-proofed. Agent/cadence//backup/due untouched.
Part 2 of the USB/backup spec. agentapi: StatusResponse.Backup record, DueResponse
age_seconds, RestoreTestStatus(). New "Rendszermentés (teljes mentés)" section
(read-only: last backup/target PBS-vs-local/next-due/restore-test) + "Mentés most"
manual trigger that goes through the quiesce loop (controller owns quiescing):
quiesce.Loop gains mutex + TriggerNow() (single-flight, async). New
/api/guest-backup/{trigger,status} (distinct from apiRouter's /api/backup/*).
App-data rows relabeled under an "Alkalmazás-mentések" divider. Config → slice 10.

Quiesce loop resumes (StartStack + clear marker) at the snapshotted phase
instead of done -> downtime whole-backup -> until-snapshot, no consistency loss.
Keeps polling to done/failed (no overlapping backup; post-snapshot failure
observed). Stop-mode fallback to done + crash-safety preserved.
