- Endpoint next to /backup/restore; handler mirrors backupRestoreHandler
(ParseForm → validStackName → backupMgr guard → WARN with RemoteAddr →
RestoreTier2Files → flash). Flash strings: "<stack>: N fájl visszaállítva a
másodlagos másolatból." / "Nincs hiányzó fájl — minden fájl megvan a helyén."
/ "Fájl-visszaállítás sikertelen: <err>" (refusals carry the Hungarian
reasons from the engine).
- backups.html: the button on the healthy Tier-2 layer row only (the
Tier2Configured branch already excludes disconnected/inactive; additionally
gated on Tier2LastRun), inline POST form with CSRF + confirm dialog naming
the additive-only semantics and the last-copy timestamp. Template gates
(id + emoji) green.
- Handler guard test (C6): traversal/empty → exact Hungarian flash, no work
started (nil backupMgr would panic if reached).
