The whole-guest tier has verify jobs; the tier holding the customer's documents and photos had none -- the complete set of restic verbs this controller used contained no `check`. We would have found out at restore time, with a customer waiting. On 2026-08-21 a deliberately damaged pack was caught at once by plain `restic check`; we had never run it. R-397: NotifyIntegrityOK/NotifyIntegrityFailed existed with no caller, the hub allowlists both event types and carries the Hungarian text for both, the settings checkbox exists, and the debug button posts to /api/debug/backup/ integrity. Everything was built except the part that runs. SIXTH instance of that shape in this project. THE HAZARD SHAPES THE WHOLE DESIGN. resticStep self-heals a crash lock by running `unlock --remove-all` and retrying, and its own comment records why that is safe: every caller holds the in-process single-flight mutex, so any lock it meets is stale. A check that did not take that flag could meet a LIVE prune's lock from this same box, remove it, and retry over the top of it. So the check TAKES THE FLAG and SKIPS rather than waits -- waiting would pin the nightly backup behind it, and a skip costs nothing because due-ness makes tomorrow try again. TestR359_SkipsWhenRunningFlagHeld asserts the NON-EFFECTS: restic never invoked, `unlock` never in any argv. Its red-proof prints the real thing -- restic running `check` while the flag was held. DUE-NESS, NOT A WEEKDAY. Daily job, weekly behaviour: "is the last successful check older than 7 days?" not "is it Sunday?". R-341 is exactly the other shape, a dated check quietly missed and never caught up. No Weekly primitive added. THREE OUTCOMES, NOT TWO. Skipped, Unreachable and failed are different facts. "I could not look" is not "I looked and it is broken" -- R-339 already owns reachability, and a second alarm for the same fact trains the operator to discount the one alarm that means the backups are damaged. A timeout is unreachable, never damage. A failure advances due-ness (a broken store must not be re-checked nightly); a skip and an unreachable store do not. Success is severity `info`, which severityNotifies DROPS -- it mails NOBODY, by design. A weekly success e-mail is how people stop reading their alerts. The customer gets a SENTENCE; restic's words go to the log, truncated (R-379: 615 bytes of raw database text reached a customer once). read-data-subset ships OFF and a malformed value is refused at read time rather than handed to restic, where one typo would fail the whole check. Published on OffboxReportStatus, NOT on report.BackupReport's IntegrityOK -- those were retired by R-331 YESTERDAY and TestBackupReport_DeadFieldsStayZero still passes unmodified. Also: the monitoring page stopped promising a Sunday job that never existed, and the debug button got its dispatch case. PART 0 WAS NOT BUILT, AND R-398 WAS MY OWN MISTAKE. The seam it asked for already exists: offboxRunner/SetOffboxRunner/m.runner() has been injectable since the off-site tier shipped, and other tests drive restic-backed paths through it. A resticStepFn seam would have been WORSE here -- it would replace the `unlock --remove-all` escalation and hide it from the assertions that must see it. R-358's AST ordering test is converted to a real execution test instead, which immediately surfaced something the AST walk could not: unlockStale legitimately runs before the restore. Four red-proofs, each printing the pre-fix behaviour. Green gate: 28 packages, rc 0. All 12 controller gates OK.	2026-08-30 21:03:29 +02:00
admin	b8af72764d	R-353/R-357/R-358/R-360: the restore tells the truth (v0.226.0) ... Four defects on the restore surface, all proven on demo-hp during the 2026-08-21 backup-truth drill, all still in shipped code. They share one acceptance idea: a restore surface must state what it actually did, and must refuse what it cannot do. VERSION NOTE. The task specifying this targeted v0.224.0 against baseline f8c9390. Both were consumed earlier the same day by R-330 (0.224.0) and R-331 (0.225.0). Drift re-confirmed against live Gitea before the first edit, operator authorised proceeding, every symbol the spec named re-verified present at the real baseline e5eee50. R-353 -- a restore that gave back nothing still said it worked. RestoreFromRecoveryUnit returned only error, so the surface printed "<app> visszaallitva (<snapshot>)." -- equally true of a run that returned an entire dataset and one that returned nothing. The count already existed and was discarded one line deep: restoreDockerVolumesFrom always returned it, the wrapper threw it away. Now (UnitRestoreResult, error), carrying replayed counts AND what the manifest LISTED, because zero-replayed has two causes that are opposite news. Three cases, three sentences, and EVERY one is a claim about the BACKUP, never about the app -- this path has no SafetyDump discriminator, and 07-backup-architecture 6.3 records that an absent dump says nothing about the app (R-361 destroyed canonical .sql files for four months). R-357 -- the destructive restore had no free-space gate. offbox_reconstitute.go contained ZERO references to offboxFree; all three existing gates guard non-destructive paths. The gate now sits before mapOffsiteRestorePaths, writeSafetyDump and StopStack, so a refusal costs nothing. Position IS the fix, which is why the test asserts StopStack was never called. No headroom multiplier (matches PlaceOffsiteRestore; the x1.1 elsewhere predicts a download). Fail closed on either probe <= 0 -- otherwise `free < need` with need==0 is FALSE and an unmeasurable scratch sails through: a gate present and inert. R-358 -- a failed download was offered as a good one. The gate answered "the directory exists and is non-empty", which is exactly what a part-way restic run leaves. Now a completion marker written 0600 atomically AFTER restic returns nil, with any stale one cleared BEFORE it starts; both orders pinned by an AST test because resticStep is not a seam. Both handlers refuse server-side: the wizard flags control a button, and a hidden button is not a guard. SCENARIO F ANSWERED, and worse than the question assumed: a unit-only scratch IS reachable through the real flow, by the most ordinary route. "Ellenorzo visszaallitas" (mode=unit, advertised non-destructive) writes the SAME directory -- offboxRestoreScratchDir ignores `full` and --include limits what restic extracts, never where -- so a customer who ran the SAFE restore was then offered the destructive one over a unit-only copy. Filed R-396; the marker closes it. R-360 -- the delete refused only while a BACKUP ran. IsRunning() is FALSE for the whole of a verification restore; the five sibling handlers all use restoreOpBlocked(). Its doc comment claimed it already did this, which is why nobody looked -- corrected in place. Red-proofs, each printing the pre-fix behaviour, in CHANGELOG and REPORT. The first R-357 red-proof exposed a hollow test OF MY OWN and it is recorded rather than quietly fixed: the fixture refused earlier at the placement stat pre-pass, so `stops == 0` passed against the pre-fix code. Fixture corrected, assertions reordered so a removed gate reports the outage rather than "no error returned". Green gate clean: 28 packages, rc 0. All 12 controller gates OK.	2026-08-30 19:31:31 +02:00
