2. Phase-0 probes

P1 — self-update wiring: PASS. self_update.enabled: true, image correct. auto_update: false is irrelevant and this was verified by reading the code, not assumed: MaybeAutoUpdate never consults cfg.AutoUpdate — that flag is the customer's opt-in to chase latest, while the FLOOR path is the managed one. Stronger evidence: update-state.json already recorded a prior initiated_by: auto-floor success (0.143.0 → 0.145.0, 2026-07-18), which proves the agent swapper is wired. Anti-flap could not block, since the persisted target was 0.145.0. 0.154.0 verified as the highest registry semver tag, so the floor <= latest gate would pass.

P2 — agent version: PASS, and it changed the plan. Built at main, self-reported felhom-agent 0.90.1, sha256 ba1d0296…, 13 734 067 bytes. But see §8.

P3 — before-state: CAPTURED (endpoint-level; no browser on DooPlex). The offsite section rendered 6× /backup/offbox/restore, 1× place, 1× reconstitute across three apps. For immich the two decisive controls were adjacent siblings differing only by label:

Helyreállítás az élő adatok közé (csak a hiányzó fájlok)   <- data CANNOT come back
Teljes visszaállítás (fájlok + adatbázis)                   <- data CAN come back

3. v0.154.0 — the wizard (3a9d744)

One „Visszaállítás…" entry per app row → GET /backups/restore/app?name=<app>; three intent cards with consequence sentences; danger styling and the R-43 double-confirm carried over verbatim; pure deriveWizardStep; no new mutation endpoint; works without JavaScript. internal/backup, internal/appbackup, internal/selfupdate, the shares/local/.fab blocks all untouched.

Latent bug fixed on the way: offboxRedirectTo hardcoded "?" when appending its flash, which against the wizard's ?name=<app> target would have buried the flash inside the app name.

Group-B red-proof (run, reverted): trivial always-INTENT impl → all 7 table rows FAILED plus the execution render test. Restored, green, git diff clean before commit.

Also caught one of my own assertions being hollow during authoring: a bare substring check for the skew/empty warnings passed on a clean pair, because the confirmFullRestore JS repeats both sentences as string literals. Tightened to assert rendered banner markup + data-restore-*.

4. v0.155.0 — the defect v0.154.0 shipped (9d1b498)

Found by the operator on the first live click-through, from the phase strip disagreeing with the progress banner on the same screen. This is the most important finding of the session.

backup.Manager carries two different "is something running" booleans:

flag	read by	set by	covers the verification restore?
running	IsRunning()	acquireRunning(), inside the goroutine	no — RestoreOffboxScratch never acquires it at all
opRunning	RestoreStatus()	BeginRestoreOp(), in the handler, synchronously	yes, all four offsite actions

v0.154.0 sourced OpRunning from IsRunning(). Verified by reading the call sites: PlaceOffsiteRestore and ReconstituteFromOffsite do acquire; RestoreOffboxScratch does not. So for „Ellenőrzés" and the full-restore preparation — the wizard's two most-used and longest actions, both streaming from restic — the execution step was unreachable. The page offered all three intents with live buttons while a restore ran; the handler would have refused any of them. That is precisely the "offering a control guaranteed to fail" dishonesty R-48 exists to remove, shipped inside the release that removes it.

Fix: restoreOpInFlight(st) behind a documented seam, fed by a single RestoreStatus() read per render, so the strip, the suppression decision and the running-op name cannot diverge. The helper sits on the handler's actual path — deliberately, so a future edit reintroducing IsRunning() fails the test rather than passing it.

Why v0.154.0's tests missed it — the generalisable lesson. The Scenario-E table proved deriveWizardStep behaves correctly given OpRunning=true. Nothing proved the handler ever computes true. A table test over a pure function proves the function, not the caller. The new TestRestoreOpInFlight_UsesDisplayFlagNotConcurrencyFlag drives a real Manager through BeginRestoreOp and asserts the render.

Red-proof (run, reverted): restoring the v0.154.0 IsRunning() shape →

--- FAIL: TestRestoreOpInFlight_UsesDisplayFlagNotConcurrencyFlag
    restore_wizard_test.go:367: a started restore op MUST read as in-flight for display
                                (this is the v0.154.0 bug)

„Eredmény" was a dead label. It never lit in v0.154.0. The strip's highlight is now its own derived Phase, separate from Step: a finished restore is back on the intent step (everything available again) while the strip reads „Eredmény" and an outcome card shows the result. Bounded by restoreResultWindow (10 min) so a stale result cannot look fresh, and bound to the app so a finished bookstack restore cannot light immich's page with bookstack's message. The card survives a reload; the flash does not. 9-row table test incl. both boundary directions and a future-clock-skew row.

5. Test + gate results

Full suite green at both commits: go build ./... && go vet ./... && go test ./... — 0 failures. All six controller design gates rc=0.

Group	Test	Result
B	TestDeriveWizardStep_Table (9 rows)	PASS
C	TestResolveWizardApp_Refusals, TestRestoreWizardHandler_UnconfiguredRedirects	PASS (302, no 500)
A	TestRestoreList_SingleEntryPerApp	PASS
C	TestRestoreWizard_ThreeIntentCards, ..._NoScratchLocksDataIntents	PASS
E	TestRestoreWizard_OpRunningSuppressesAllMutations	PASS
D	TestRestoreWizard_NoNewMutationEndpoints, ..._FieldContract	PASS
new	TestRestoreOpInFlight_UsesDisplayFlagNotConcurrencyFlag	PASS (red-proofed)
new	TestHasRecentRestoreResult (9 rows), TestRestoreWizard_ResultCard	PASS

Two pre-existing tests coupled to the old IA were inverted, not deleted: TestAppRow_RestoreLists and TestBackupsSplit_SectionsOnExactlyOnePage now assert the mutation forms are ABSENT from the list.

6. STOP-1 — single-fire self-update: BANKED

Operator saved global floor → v0.154.0. Timeline (host CEST / guest UTC, 2 h offset):

06:57:13Z  UpdateState "pending"                   initiated_by=auto-floor
06:57:17Z  agent WARN  controller swap requested   0.153.0 -> 0.154.0
06:57:19Z  agent INFO  image file written, restarting bootstrap
06:57:21Z  container StartedAt · UpdateState completed_at
06:57:29Z  agent INFO  new controller healthy

Assertion	Result
controller swap requested	1
image file written, restarting bootstrap	1
new controller healthy	1
rollback / swap-failed / unhealthy	0
container RestartCount	0
bootstrap unit NRestarts / Result	0 / success

UpdateState persisted status: success, 0.153.0 → 0.154.0, initiated_by: auto-floor. VerifyStartup banked it on the next boot (Post-update startup: update successful), and the 06:57:52 periodic check reported Current version 0.154.0 is up to date — the anti-flap correctly doing nothing now that current ≥ floor. Exactly one swap, no storm, no rollback. This closes the leg R-23(a) was missing: the earlier floor save proved nothing because it targeted an already-running version.

Methodological caveat, disclosed: the 30-minute no-re-attempt window was contaminated by my own action — I hand-deployed v0.155.0 at ~07:16Z, mid-window, which restarted the container and the bootstrap unit. The agent-side counters are unaffected and remain the load-bearing evidence (a hand-deploy writes /etc/felhom-controller-image and restarts the unit directly via pct exec, never through SwapController), but the container-side counters after 07:16Z reflect my deploy, not the self-update. Between 06:57 and 07:16 — 19 uninterrupted minutes — there was no second attempt.

7. Live validation

Method: endpoint-level (no browser on DooPlex) plus the operator's own UI click-through.

Operator, in the browser (v0.154.0): list page → one „Visszaállítás…" per app; wizard → three cards, pair-honesty panel showing adatbázis-mentés ideje: 2026-07-19 12:28; ran one Ellenőrzés; result A(z) immich visszaállítva ellenőrző mappába: /mnt/felhom-drives/hdd_1/backups/offsite-restore/immich (a meglévő adatok változatlanok). Non-destructive as designed.

Endpoint-level, after the v0.155.0 fix — the proof the defect is gone. A real Ellenőrzés run through the actual endpoint:

moment	phase strip	<form> count	note
before	Előkészítés	3	intents offered
mid-flight	Végrehajtás	0	Jelenleg egy mentési vagy visszaállítási művelet fut (immich).
after	Eredmény	3	result card names the scratch path; intents available again
bookstack, same moment	Előkészítés	—	no result card — app-binding holds

Under v0.154.0 the mid-flight row would have read Előkészítés / 3 forms. Before/after on the list page: 6 restore + 1 place + 1 reconstitute forms → 0, and 3 wizard entries. Refusal path: unknown app → 302 + Hungarian flash, no 500.

Deploy verified: felhom-controller:0.155.0 | Up (healthy), RestartCount=0.

8. Part 3 — STOPPED, then ruled

Part 3 asked me to publish + deploy v0.90.1 as "R-39's cheap half — the PBS wrapper argv fix", while Rule 12 forbade touching the wrapper. Both cannot hold, because the fix IS the wrapper:

• 9596d5a changes zero non-test Go files — CHANGELOG.md, REPORT.md, configs/felhom-pbs-apply, internal/pbsdr/manager_test.go. Its own message: "the Go binary is unchanged."
• felhom-pve already has it — wrapper hotfixed 2026-07-18, args=(--fingerprint "$fp") at L107, .bak-20260718-preR39 retained.
• New hosts get it too, unversioned — felhom-host-install.sh:1914 fetch_raw pulls the wrapper from raw/branch/main, and 9596d5a is an ancestor of main.

Publishing would have delivered no behaviour change, restarted a production agent at a remote site for nothing, and — once the Day-0 manifest was saved to 0.90.1 — advertised a versioned fix the artifact channel never carried. Registry pre-check confirmed and left as found (0.90.1 → 404, 0.90.0 → 200).

Operator ruling: leave 0.90.0 published; record the closure in the docs. Done in ROADMAP.md (c35da9d). The stop surfaced a genuine new defect, filed as R-50b: a root-owned privileged host artifact is delivered unversioned from main, absent from the Day-0 manifest, so "which wrapper is on this host?" is unanswerable from any manifest.

9. Doc state

• Capability map row 61 → PROVEN-LIVE (ce8c539).
• ROADMAP: R-48 → SHIPPED; R-39 cheap half recorded as closed-in-field with the publish cancelled; R-50b filed (c35da9d).
• Not flipped: the R-23(a) map row and the "config/state round-trips in seconds" row — the evidence now exists (§6), so these are ready to flip; held only because the 30-min window carries the disclosed caveat above. Recommend flipping with the 19-minute clean interval cited explicitly.

10. Remaining — human

1. Floor → v0.155.0 at your convenience, so the fleet matches the box (9201 is hand-deployed and above floor, so nothing is pending on it).
2. TASK-B ruling (R-39 primary half: the descriptor-hash re-apply gap).
3. R-50b ruling — recommendation is (a): record the wrapper's sha256 in the Day-0 manifest and have the agent report the installed file's hash, so drift becomes visible.
4. C6 customer-restore pass for the alpha.

11. Observations

• The most valuable finding came from the operator, not the tests. The phase strip he questioned was the visible symptom of a real bug — the strip and the progress banner disagreeing on one screen. A UI element that renders derived state is an assertion the customer can check; that is worth more than its decorative cost.
• docker_run_volume_path_gate.py fails at HEAD, unrelated (internal/appexport/estimate.go:179). Verified pre-existing by stashing and re-running. Left alone — but that gate is currently not a usable signal.
• opstatus.go says in its own header that it is the DISPLAY surface and does not gate concurrency. I read the concurrency flag anyway. The file told me; I did not check.
• felhom-pve is up and healthy (agent 0.90.0, active) — the "agent is DOWN" TEMPORARY block in felhom-controller/CLAUDE.md is stale and should be trimmed on return.
• P3's accented-grep trap fired as documented — used a local Python pass over fetched bytes rather than grepping accented patterns through ssh → pct exec → bash -c.
