 | R-85 | **The DR tier must be restore-tested UNATTENDED, and its failure must be HEARD** | M | **Code SHIPPED (agent v0.104.0 + hub v0.77.0, 2026-07-27); rotation NOT YET OBSERVED LIVE** | R-82 proved a PBS restore round-trip **by hand**. Three defects kept the unattended path from covering it, each verified at source: **(a)** `buildRestoreTestScheduler` took `cfg.Backup.BackupTarget()` and built ONE runner on it, so the offsite tier's archives were never candidates; **(b)** the `Spec` was an immediately-invoked function evaluated ONCE at daemon start, so nothing tier-varying was expressible and any storage-type/config change stayed stale until restart; **(c)** a failed restore-test was a `[WARN]` log line with **no event, no notification, no gauge** — true for the LOCAL tier that was already being tested, so the loudest DR signal this system produces was inaudible. (c) is the one that mattered: rotating tiers without it would only mean two tiers can fail silently instead of one. **Selection ruling (operator, 2026-07-26): oldest-first (Option 1)** — never-proven sorts first, which is where the offsite tier starts; no new cadence knob. The per-tier last-proven timestamp is now reported **so the achieved interval can be MEASURED before anyone decides whether a knob is needed** — measure, then configure, not the reverse. **Shipped:** per-run `SpecBuilder`; `PickRestoreCandidateOn` (a tier with no archive NO-OPS, never fails); persisted `RestoreTestState` (rotation survives a restart — credit only on SUCCESS, or a permanently failing tier looks freshly proven); `backup.InFlight`, the host-wide one-heavy-op gate shared with the backup path (a LINK concern, not a lock one — an offsite restore pulls multi-GB over the tunnel a backup pushes one); and hub `restore_test_failed` / `restore_test_stale`, kept **distinct** and anchored on R-81's verdict structure, operator-tier only. **NOT yet proven:** rotation has not been observed selecting both tiers across consecutive unattended cadences — a multi-day window at a 24h cadence. Manual restore-proof IS proven (R-82). |
 | R-86 | **Backup-ALIGNED restore-test scheduling — test a tier ~1 day after ITS OWN backup** | S | **NEXT — operator ruling 2026-07-27** | R-85 schedules restore-tests on a free-running INTERVAL and rotates oldest-proven-first. That cannot express *"the day after the PBS backup"*: any fixed offset drifts against the backup schedule, so alignment would be luck rather than design. **The ruling:** weekly per tier (daily is overkill), timed **~1 day after that tier produced a new backup** — so the gap between an archive being written and being proven stays small, and a tier is never proven against an archive about to be pruned (offsite retention is 2 weeks). **Shape:** trigger a tier from **its own last successful backup** rather than a clock — test tier X once its newest archive is ~24 h old and not yet proven. Self-aligning when a backup runs late, and it naturally stops testing a tier that has stopped producing backups (today an interval keeps re-testing the same stale archive). Needs the scheduler to consult per-tier backup times (already available: `BackupRunner.NewestArchiveTime`, R-84) alongside `RestoreTestState` (R-85). **Interim in force:** `restore_test_cadence_seconds = 302400` (3.5 d) on both boxes — oldest-first over two tiers lands each tier ~weekly, which matches the cadence half of the ruling but NOT the alignment half. |
 | R-87 | **The restic (app-data offsite) tier is NEVER restore-tested** | M | idea — surfaced 2026-07-27 while closing R-85 | **R-85 covers whole-guest vzdump tiers only** (`local`, `felhom-pbs`); the agent has no restic surface at all. restic is the CONTROLLER's app-data offsite backup to the Hetzner Storage Box, a separate mechanism — so the tier that is arguably most important to a customer is the one nothing verifies. It is the only tier that survives losing the box **and** carries their actual app data: the whole-guest snapshot deliberately excludes the bind-mounted data drives (`/mnt/felhom-drives`). Restore code exists and has been exercised BY HAND (the immich destroy-and-recover drill, PROVEN-LIVE), but nothing tests it unattended — **exactly the state PBS was in before R-85: it works when someone tries it, and nobody would know if it stopped.** Needs its own design: a restic restore-test is controller-side, has no scratch-guest analogue, and would verify into a scratch dir rather than a booted guest, so R-85's machinery does not transfer. |
+| R-88 | **An UNREACHABLE backup target reads as "no backup exists" → the agent fires a doomed backup at it** | S | idea — observed live 2026-07-27 | **The R-81 class (absence-is-not-failure), reappearing one layer down in the AGENT's due-check.** R-84 replaced the in-memory `Store` with storage ground truth (`NewestArchiveTime`), and fails safe on a read error by *falling back to the in-memory record* — "never fake freshness, never suppress". That fallback is correct in isolation but wrong in the one composition where it actually runs: **a cold store plus an unreachable target.** After a restart the in-memory record is empty, so the fallback answers *no backup has ever been recorded* → tier due → the agent fires a backup at the very storage it just failed to read. **Observed:** `felhom-agent` restarted on demo-felhom at 07:02:57 UTC; `local-api: could not read the backup storage for the due-check — falling back to the in-memory record` (vmid=9201 target=felhom-pbs); 11 s later `vzdump 9201 → felhom-pbs` failed with `could not activate storage 'felhom-pbs' … Can't connect to 10.77.0.1:8007 (Connection refused)`. The offsite PBS service was down at the time — so the trigger was real, not synthetic. **Bounded, not severe:** the doomed backup fails in ~0 s at storage activation, so it is not the wasted multi-hour WAN upload R-84 was written to stop; the cost is a spurious `backup failed` event per restart, and potentially a stream of them if the link flaps. **Shape:** distinguish *storage unreachable* from *storage readable and empty*. Unreachable is UNKNOWN — defer the due-verdict rather than resolving it either way, exactly as R-81 made the hub do with a missing report. Only a target that is reachable AND has no archive is genuinely due. Note this does NOT weaken R-84's fail-safe intent: a tier whose storage is merely slow or briefly unreadable should still err toward backing up — it is specifically the **cold-store + unreachable** pair that must defer, because there the fallback has no information at all, only an empty default that looks like a fact. |
 | R-76 | **FileBrowser-created folders break the setgid chain, and a drop-zone's mode is not stable** | S | idea (surfaced by the R-75 spike, 2026-07-26) | Two related findings from `audits/SPIKE-catalog-data-paths-2026-07-26.md` P3/P5, both **pre-existing** and deliberately left alone by that spike. **(a)** FileBrowser Quantum 1.3.3 creates files `0644` and folders `0755` and does **not** propagate the setgid bit — even though the entrypoint wrapper's `umask 002` really is in effect (`/proc/1/status` `Umask: 0002`). Group inheritance itself works (a file uploaded into a 2775 group-100 dir landed group 100, not the process gid 1000), so the convention's *group* half holds and only its *mode* half is lost. The consequence is proven with a control: inside a UI-created `0755` folder a gid-1000 process's file landed group **1000**, while the identical write into the 2775 parent landed group **100**. So **any folder a customer creates through FileBrowser breaks the shared-group chain one level down.** Latent today — every userdata-touching catalog app that declares an identity declares uid/gid **1000**, the same uid FileBrowser runs as, so owner permissions mask it; it bites the day a content app runs as a different non-root uid with gid 1000. The comment at `infra/infra.go:156` is right that the image ignores `-e UMASK` but does not say the wrapper fails to achieve the intended mode either. **(b)** `import/calibre` is live on demo-felhom at `755 1000:1000` where every sibling is `2775 root:1000` — with `media/books` on the same box, same app, same deploy, at `2775` as the control, and no parser asymmetry (checked: `ParseComposeUserdataMounts` picks up both calibre-web binds). Consistent with the consuming app rewriting the mode of its own ingest dir after the deploy belt sets it; **not confirmed causally**. Together they mean **a drop-zone directory's mode is not stable against either the customer or the consuming app** — verify before building anything that assumes `import/*` stays 2775. Flips no capability-map row today (latent); would become customer-visible the moment a non-1000 content app enters the catalog |
 | R-21 | **Bare-metal Felhom ISO** — per-PVE-release auto-install ISO for blank customer hardware → first-boot wrapper (invokes `felhom-host-install.sh`) → universal secret-free / operator-bind (option C) | XL | **SHIPPED + PHYSICALLY CLOSED (slices A+B+C; rehearsal executed 2026-07-18)** | **PHYSICAL CLOSURE 2026-07-18** (`tests/VALIDATION-n100-rehearsal-2026-07-18.md`): the generic pairing ISO v1.20.0 (`--loader mkimage`, SB off) **booted the very AMI board that F1 blocked**, installed unattended, and the box self-registered as an unclaimed appliance the same second it first booted (16:17:14) → self-bind → credential → day-0 SUCCESS 16:32:32 → floor-lifted to current. **F1 is closed on physical hardware and the rehearsal dependency on this item is discharged.** Two residual notes stay open, neither blocking: PXE/network-boot is still unbuilt (the third F1 option, for boards where even USB-mkimage fails), and mkimage remains unsigned → **SB must be OFF**.

Pipeline must ship a firmware-compatible loader / PXE path. Reused-customer edges (F2 claim re-issue, F3 offsite re-issue, F4 non-default-storage-id ACL 403) feed R-1/Peti. UX: F6 drive-init doesn't mount+attach, F5 guest-RAM not configurable, F7 back-route. — **Slice A (build pipeline + first-boot bootstrap) DONE + validated on VM 310:** build gate/red-proof, disk-filter fail-safe, stub→retry-unit→real public-channel host-install fetch+invoke→retry, resume-decision, exactly-once, no-net retry+recovery all GREEN. Operator-gated remainder: host-install rc-0 terminal success (drill customer needs the password-gated create-UI). **Slice B — SHIPPED (scripts v1.18.0, 2026-07-17):** the F1 firmware fix is now a first-class pipeline mode `build-felhom-iso.sh --loader shim|mkimage` (default shim; `mkimage` = monolithic grub-mkimage loader from the ISO's own GRUB, recipe from the run evidence). RUNBOOK-B legs on nested VM 311 proved it: shim boots+installs under OVMF SB-enforcing + SeaBIOS; mkimage boots+installs under OVMF SB-off; mkimage under SB-enforcing FAILS `Access Denied` (unsigned → **SB must be OFF**, documented); surgery byte-identical payload. **Physical N100 boot on the real board still pending** → folds into the supervised rehearsal (R-1; an `n100-safety` match-nothing ISO is built + sha-recorded for a zero-risk pre-flight). **PXE/network-boot** (the third F1 option, for boards where even USB-mkimage fails) stays a deferred note under this item — not built. **Slice C — SHIPPED (hub v0.62.0 + scripts v1.19.0, 2026-07-17):** the GENERIC secret-free universal ISO (`build-felhom-iso.sh --pairing`). The box self-registers as an unclaimed appliance (keyed by SMBIOS-uuid + MAC set — the DMI-verdict tiebreaker), the operator BINDS it to a customer on the Hosts page, and the hub delivers customer-id + retrieval passphrase ONCE (`/api/v1/appliance/register` + one-shot poll, 404-no-oracle — all live-verified through the public ingress); the bootstrap then falls through to the slice-A direct path. **One unit, two modes** (direct = byte-identical, regression-proven zero-appliance-calls). Artifact proven secret-free (baked env = hub URL only; manifest `secret-bearing: no`). The **bind is operator-password-gated** → the live boot→register→bind→day-0 composition (with a Viktor-created drill customer) + the physical N100 boot fold into the supervised rehearsal — **which now runs the COMPLETE final product flow in one pass: RESET the demo → boot the generic ISO → bind → day-0**. SSH-host-key pinning: stored + fingerprints displayed (attaching to the host on bind = future, no clean hand-off surface today). **Customer-facing self-bind page = R-27 (future).** Origin spike `audits/SPIKE-baremetal-iso-2026-07-16.md`: every mechanism GREEN on nested virt (VM 310 on felhom-pve). Zero-touch install BIOS **and** UEFI incl. **Secure Boot enforcing** (no MOK/keypress); first-boot hook `fully-up` = root + working pvesh/pct, exactly-once via `pending-first-boot-setup` flag; post-install **webhook** carries SMBIOS-UUID + management-MAC + host SSH keys → the unclaimed-appliance record; disk-filter installs only the target (canary byte-identical) and **fails-safe** on match-nothing / bad disk; `from-url` + `cert-fingerprint` **fails CLOSED**. OPEN (needs ONE real bare-metal run): vendor DMI serials (empty on virt), real firmware/NIC quirks, a pre-existing-LVM wipe step. Pipeline notes: assistant pairs to the ISO by Debian codename, ~11.5 s/ISO on DooPlex, **gate on `validate-answer` output not `$?`** (exit 0 on failure). Would flip a new capability-map MISSING row "customer self-installs on bare hardware" once spec'd. *(brief called this R-22)* | **SECOND-HARDWARE PROOF 2026-07-21 (slice C, demo-hp): the pairing flow is no longer a one-board result.** The universal secret-free ISO was booted on a completely different machine — an **HP t740 (Ryzen V1756B, AMI M42 firmware)** versus the N100 it was proven on — and the whole chain ran on **virgin hardware in one pass**: armed install → self-registration as an unclaimed appliance → operator bind → day-0, ending with a running customer guest 9201 and agent 0.92.1 checking in as host `demo-hp-bb76ea`. **Two things generalise from the second board specifically:** the **shim** loader booted with **Secure Boot ENABLED** (`mokutil --sb-state` → `SecureBoot enabled`), confirming the mkimage/SB-off dance is an N100-firmware workaround and NOT a Felhom requirement; and the exact-serial disk filter selected the SanDisk system SSD while leaving the box's **1TB NVMe untouched and unenrolled** (its prior NTFS partition is still intact, unmounted, in no LVM/ZFS) — the destructive path stayed inside its filter on hardware it had never seen. **Not clean, and the failures are filed:** the install got no DHCP on the 4-port NIC and baked a static fallback rather than aborting (**R-59**), which cost a cable move and a hand-repair; and the console was unreachable because the baked root password is unknowable (**R-61**)
 | R-29 | **The design-v2 green gates are not enforced anywhere — one has been RED for 16 releases.** `controller/scripts/docker_run_volume_path_gate.py` has failed continuously since **2026-07-14 (v0.129.0)** and nobody noticed until R-7b's close-out ran it by hand at v0.145.0. Two separable parts. **(a) The finding itself is benign and the fix is 3 lines.** The flagged call is `internal/appexport/estimate.go:179` `docker run --rm -v <volumeName>:/vol:ro alpine du` — a **NAMED-VOLUME** mount, i.e. daemon-side with no host path, which is the *safe* shape and byte-for-byte the same pattern as three entries already on the gate's ALLOWLIST (`export.go` `volName+":/vol"`, `backup.go` `volName+":/vol:ro"`, `restore.go` `volName+":/vol"`). It is NOT the v0.124.0 path-strand class the gate exists to catch — the author of the v0.129.0 F-A fix explicitly avoided that class (see the function's own comment) and simply never added the allowlist entry. So the fix is an ALLOWLIST addition WITH ITS WHY, **not** a docker-cp rewrite; anyone who 'fixes' this by rewriting the call has misread the gate. **(b) The systemic half is the real item:** the gates run only when a human remembers to run them, so a gate can sit red across 16 releases while every REPORT says 'green'. This is the SECOND instance of the class — cf. the v0.123.0 note *'Windows green gate silently red (read-only fsync)'*. Decide where they run (pre-push hook, `build.sh` step, or a CI job) and make a red gate block the train the way the Go green gate does. | S (a) / M (b) | idea | Origin: R-7b close-out, `felhom-controller` REPORT §4(f) — CC correctly left it alone as out-of-scope and pre-existing, and verified by stashing that it fails identically on the unmodified tree. Flips no capability-map row (engineering hygiene, no customer-visible behaviour). Affected gates to audit for the same rot: controller `template_id_gate` / `emoji_gate` / `native_confirm_gate` / `offbox_rename_gate` / `mojibake_gate` / `app_row_dedup_gate` / `docker_run_volume_path_gate`, hub `hub_confirm_gate`, manifests `manifest_bearer_gate`, website `site_gates`. **Do not bundle (a) into an unrelated feature commit** — it is a one-line behavioural claim about a mount's safety and deserves its own reviewed diff. **2026-07-18 rehearsal note:** the run's finding list independently re-raised "assign the pre-existing `docker_run_volume_path_gate` failure its ID so red stops normalizing" — **that is this item; no second ID was minted.** |
