# OPEN-ITEMS — the single source of truth for open work

**Rebuilt 2026-07-27 by read-only triage.** `ROADMAP.md` keeps the full history and reasoning; this
page keeps only what is **open**, and it is the file to read first. Root `REPORT.md` is per-session
and **overwritten** — nothing durable may live only there; a session that must not clobber it writes
a non-overwritten `REPORT-<topic>.md` sibling instead (`CLAUDE.md:82-87`), of which 14 now exist.

State: `BLOCKED` · `READY` · `WAITING-ON-OPERATOR` · `WATCHING`. Every row has an owner.

| ID | What | State | Blocked on | Next action | Owner |
|---|---|---|---|---|---|
| **R-88a** | ~~Failing backup re-quiesces every 5 min, no backoff~~ | **SHIPPED** (controller v0.176.0, 2026-07-27) | — | Live on both boxes; breaker 15m→4h, per-tier, never permanent | — |
| **R-88b** | ~~`/backup/due` cannot say *unknown*~~ | **SHIPPED + PROVEN-LIVE** (agent v0.105.0 + controller v0.178.0, 2026-07-27) | — | `age_state=unknown` captured on real hardware during a deliberate ep0 outage; controller deferred, **zero app stacks stopped** | — |
| **E-2d** | **Prove E-2 on a fresh VM** — a real `felhom-host-install.sh` 1.22.0 run, Case B naturally, a claimable customer, then add a drive (the offer) and unplug it (`backup_target_absent` end-to-end) | **CLOSED — PARTIALLY PROVEN** (2026-07-29) | — | **C1, C2 proven** (`audits/E2D-fresh-vm-2026-07-29.md`); **C3, C4 proven live** (`audits/SESSION-C-2026-07-29.md`); **C5 FAILED → R-116** — the gate fires and an alarm reaches the hub, but it is the generic event, so the alarm and its recovery cannot be paired. **R-116 is the single named open leg**; per the Session-C runbook §9, decided in advance, a failed claim closes the item as partially proven rather than triggering a re-run. Both audits carry the full record — the `local-lvm` fence, the ISO/PAIRING derivation, the Phase 0 answers, the per-claim observables and the teardown evidence — and are the place to read it, not this cell. **The arc's actual definition of done is R-106 + R-109, R-108 and D5**, none of which this detour touched | CC |
| **R-94** | **A hand-synced version constant drifts, and the gate that would catch it is never run** — `hub/internal/web/configs.go:28` pins `hostInstallVersion = "1.19.0"` while `scripts/felhom-host-install.sh:187` is `SCRIPT_VERSION="1.22.0"` | **READY (XS)** | — | **CORRECTED 2026-07-29 — the earlier framing of this row was false and is retracted.** The constant selects no script: its only consumers are `configs.go:487` (`ScriptVersion`) and `render_test.go:219`, and it renders as a label at `customer_unified.html:494`. The install command beneath that label fetches `https://felhom.eu/scripts/felhom-host-install.sh` (`customer_unified.html:563`, `:1262`), which the website git-syncs from `main` on a 30 s period (`manifests/webpage.yaml`) — so **1.22.0 is what every install already gets** (live fetch, 2026-07-29). Every flag the generator emits is parsed by 1.22.0 (`customer_unified.html`~`:1210`–`:1238` vs `felhom-host-install.sh:1177`–`:1210`): **no functional gap, only a wrong number on the operator's screen.** Three legs, all XS: **(a)** derive the label from `SCRIPT_VERSION` rather than hand-syncing it, or delete it; **(b)** `scripts/hostinstall_gates.py` **fails today** and is invoked by no Makefile, hook or `CLAUDE.md` — wire it next to `site_gates.py` or delete it, because a gate nobody runs reads as coverage it is not providing (**this leg is one instance of → R-29**, which is the class: gates are enforced nowhere, and the enforcement decision belongs there, not here); **(c)** `render_test.go:219` compares the constant to itself and passes at any value — replace it with the cross-file assertion. **No longer blocked on E-2d** — it never gated anything. **2026-07-29: a real 1.22.0 install has now happened** (`audits/E2D-fresh-vm-2026-07-29.md`), so even the original (retracted) precaution is discharged — nothing stands in front of this row | CC |
| **R-110** | **`main` is the installer's publish channel — there is no staging.** `manifests/webpage.yaml` git-syncs `/scripts/` from `--branch=main` on a 30 s period and nginx serves that working tree directly (`location /scripts/`, `root …/current`). So pushing `scripts/felhom-host-install.sh` **is** publishing it: within thirty seconds it is what every subsequent `felhom-bootstrap.sh` fetch (`scripts/iso/felhom-bootstrap.sh:96`) and every operator-run day-0 command (`customer_unified.html:563`) receives. There is no tag, no pinned-version path, no staging copy and no rollback other than another push — for the artifact that runs as **root on a virgin box**, the single most privileged thing Felhom ships | **WAITING-ON-OPERATOR (S)** | operator ruling | **Two consequences worth stating:** E-2d is not a gate *before* exposure — 1.22.0 has been the live installer since it hit `main` on 2026-07-29 — and the precaution recorded on the old R-94 row as "do not point every new box at an installer that has never run" **was never available to take**. **Open question for the operator, not a defect to fix blind:** whether `/scripts/` should serve a pinned release (tag-tracked path, or a versioned directory with the customer command naming a version) or whether `main`-tracking is the accepted shape for a one-operator product. Exposure today is zero — there are no boxes installing — which is exactly why it is cheap to decide now. **SECOND INSTANCE, found 2026-07-29 by the E-2d run and filed here rather than as a new ID:** `felhom-host-install.sh` fetches **nine** files from `raw/branch/main` (`:2072`–`:2206`) and the hub manifest vouches a sha for exactly **one** (`wrapper_sha256` → `felhom-pbs-apply`; re-checked this run, no drift). E-2a's `felhom-backup-target-apply` (`:2116`) is installed **0755 to `/usr/local/sbin` and root-fenced in sudoers**, validated only by `bash -n` — a root-executed artifact taken from `main` with no pinned integrity, which is this row's class exactly | CC |
| **R-111** | ~~**The Day-0 artifact channel is 17 agent releases stale — a box installed today gets agent `0.96.0`, not `0.113.0`.**~~ `felhom-host-install.sh` does not use `main`: it reads the hub-vouched manifest (`:423-436`) and fetches Gitea generic packages (agent `:1945`, golden `:2573`). Gitea's newest are **agent 0.96.0** and **golden 0.161.0**, and the hub's manifest selects exactly those — so a fresh box lands on **agent 0.96.0 + controller 0.161.0** (global floor `v0.156.0` < the golden's 0.161.0, so no self-update) against `main`'s 0.113.0 / 0.185.1. Agent 0.113.0 reached both demo boxes by **direct deploy and was never published** | **SHIPPED 2026-07-29 — the channel now serves agent 0.113.0 + golden 0.185.1** | — | **FIXED the same day it was found.** Agent **0.113.0** built from the clean tree @ `58b598b` and published (`scripts/publish-agent.sh`), sha `5f3247f756cb658e…`, round-trip GET verified. Golden **0.185.1** baked on the nested drill VM embedding controller `0.185.1`, published, sha `dba00f3e845c415e…` — bake clean: `Result=success`, overlay2, **all 3 mounts included** (rootfs+mp0+mp1), 0 FATAL/exclusions, upload HTTP 201, token-leak grep 0; log `drill/bake-0.185.1.log`; GL-1 teardown done (guest 9100 purged, secrets shredded, disk restored to `virgin`). Hub Day-0 manifest moved **both together in one POST** so it never vouched a new agent against an old golden; `min_agent` **0.93.0 → 0.113.0**, which is what controller v0.185.0 declares (`felhom-controller/CHANGELOG.md:15`) — **zero fleet impact, verified: all three enrolled hosts already run agent 0.113.0, so no box is held.** `wrapper_sha256` preserved verbatim (re-checked against `configs/felhom-pbs-apply` — no drift). **The global controller floor was deliberately NOT raised**: the golden now bakes 0.185.1, so a fresh box needs no self-update, and raising it would have been an unnecessary fleet-wide write. Original finding follows. **Found 2026-07-29 by the E-2d Phase 0 gate, which stopped the run before a VM was created.** 17 unpublished releases (v0.97.0–v0.113.0) strand the **entire R-82 tiered-backup arc** plus **F-CRIT-2** (a failed backup looking fresh — 7 days silent) and **F-REBOOT** (a guest rebooted mid-backup never returns): a new customer's box would install without them. **Blocks E-2d's C3/C4/C5** — those test endpoints and events that do not exist in 0.96.0/0.161.0. The **controller is fine** (registry has 0.185.1, floor-driven self-update), so the gap is specific to the two Gitea-generic artifacts. **Mirror of R-110, not a duplicate:** R-110 = the installer publishes instantly with no staging; R-111 = the agent/golden publish gate exists and was never walked. Fix should decide whether publishing joins the release train rather than staying a remembered step (R-29's shape, one layer up). Evidence: `audits/E2D-fresh-vm-2026-07-29.md` **DEFERRED LEG, AND IT RECURRED → R-115.** This row's shipped half stands and is not reopened: the bump happened, was verified, and was proven end-to-end by the E-2d install. But its own closing line — *decide whether publishing joins the release train rather than staying a remembered step* — was never acted on, and agent 0.114.0 reproduced the exact condition the same afternoon. The recurrence is filed as **R-115**, not as a reopen, because the stale-channel finding is closed while the process defect that caused it is a distinct problem with a distinct fix. | CC |
| **R-115** | **Publishing is a remembered step, and it was forgotten within eight hours of being documented as forgettable.** A box installs the agent from a Gitea generic package the hub explicitly vouches, never from git. Nothing in the build, deploy or session-end path publishes or checks that a version was published — so "deployed" and "installable" are independent states that drift silently. **Two instances, both real:** **R-111** (2026-07-29 morning) — 17 agent releases v0.97.0–v0.113.0 stranded, so a new customer would have installed without the entire R-82 tiered-backup arc plus F-CRIT-2 and F-REBOOT; found only because the E-2d Phase 0 gate happened to look. **Agent 0.114.0** (same afternoon) — the R-113 fix, built and pushed at `b58d7bc`, deployed to felhom-pve, and **unpublished until this task**, which blocked Session C: a fresh drill box would have installed 0.113.0 and proven the bug rather than the fix | **WAITING-ON-OPERATOR (M)** | operator ruling on the release process | **The finding is the RECURRENCE, not either instance** — both instances are fixed. R-111's own text already named this leg (*"decide whether publishing joins the release train rather than staying a remembered step"*) and closed SHIPPED without it; the leg then recurred the same day, which is the evidence that a note is not a mechanism. **Class: → R-29, one layer up** — a control that exists and is never walked; deliberately NOT given its own ID. **The decision is the operator's; the options, mechanisms first:** (a) **publish as a step in the build/release path**, so deployed and installable cannot diverge; (b) **a gate that refuses to deploy a version that is not published+vouched** — the strongest, and it fails closed; (c) a session-end checklist entry; (d) accept it as manual and add a pre-Session-C verification. **(a) and (b) are mechanisms; (c) and (d) are reminders — and R-29's whole finding is that reminders do not hold.** No code this session by design | CC |
| **R-116** | ~~**The drive-absent alarm and its recovery were a MISMATCHED PAIR — absent fired the GENERIC `storage_disconnected`, return the SPECIFIC `backup_target_restored`; `backup_target_absent` never fired at all**~~ | **SHIPPED + PROVEN-LIVE** (agent v0.116.0, 2026-07-30) | — | **CLOSED. The full four-event sequence, on the wire, on a fresh box** (`audits/R116-v0116-2026-07-30.md`): `backup_target_absent (error)` on detach → `backup_target_restored (info)` on return for the TARGET, and `storage_disconnected (error)` → `storage_reconnected (info)` for a NON-target drive on the same box four minutes apart. **Two matched pairs, correctly discriminated — and discrimination is proven NON-trivially for the first time**, since both prior runs had the target itself emit the generic event. Gate fired in **3 s**; all four events reached the hub, so the specific alarm, its severity, its Hungarian copy and the hub routing are now exercised end-to-end. **Over-correction PASSES with a positive observable** (0 ABSENT lines / 0 drive events over 2m14s with both drives present, target `degraded:false`, while 2 `RETURNED` lines prove the gate was ticking). **NARROWED by the R-117 spike (`audits/SPIKE-r117-bind-liveness-2026-07-30.md` §12), and it stands as written:** the 2 `RETURNED` lines are a genuine positive observable, so rule 3 is satisfied — but `degraded:false` over that window was read off a drive whose bind was **dead** (R-117), so the window evidences **"the gate did not over-fire"** and **NOT** **"the drive was healthy."** No other part of this row changes: every input to the pairing fix is configuration-derived (`storage.cfg`'s `path` vs the `.mount` unit's `Where`), which R-117 does not touch. Ran on a nested PVE on **demo-hp** per `runbooks/target-selection.md` — through the **real day-0** from the v1.25.0 ISO, with the agent **installed unaided from the vouched Day-0 manifest** (published sha `b47c5c4dab641ee5…`, independent registry GET verified, manifest read back), drives enrolled through the real endpoints, device loss a real hot-detach. **THE FIX, and the ruling is the substantive part:** the mechanism was first isolated from the captured payload (`DIAG-r116-disks-payload-2026-07-30.md`) after two fixes aimed at shapes that do not occur. **Both smaller-looking options were REJECTED because they regress R-114** — `backup_target_offer.go:79` reads `BackupTarget && MountPath != ""` as *"a real drive with its own mountpoint — healthy"* and returns before its `TargetAbsent` branch, so back-filling `MountPath` on the Observe row **or** flagging the registry row (whose `MountPath` is the stale unit-file value) would have told the customer the backup target is fine while its drive was gone. **R-114's correctness was resting on R-116's bug** — a coupling invisible until the payload existed. Taken instead: the Observe row gets the **guest path only** (`mount_path` stays `""`, which is true) from a new `ConfigPath` (`json:"-"`, so the cross-repo golden + key-set contract is untouched), and the union row is deduped **on guest path** — the join being CONFIGURATION (`storage.cfg`'s `path` vs the `.mount` unit's `Where`), the only identity that survives the device. Tests 845→849; 4 red-proofs each asserted to land, and red-proof 1 replays v0.115.0's code and fails, which is the empirical proof it was inert. Its green test had supplied a `MountPath` production never supplies AND left `DriveTargets` nil so the union loop never ran — both corrected. v0.115.0 left in place (inert, harmless). Teardown all 3 layers; hub layer gate-blocked on ONLINE with the command recorded. **Caveat: the drill's controller was 0.185.1 from the golden, which PREDATES R-114**, so its absent-state banner showed the old false copy — the golden being a release behind, not a regression → **R-120** | — |
| **R-120** | ~~**The golden baked a controller that predated R-114 + R-112, so a FRESH box showed the customer the WRONG absent-target message**~~ | **CLOSED — golden rebaked + PROVEN-LIVE, and the class now has an ENFORCED gate** (golden 0.186.0 + hub v0.82.0, 2026-07-30) | — | **`audits/R120-golden-rebake-2026-07-30.md`.** **Half 1 — the artifact.** Golden **0.186.0** baked from `main`'s controller in the DooPlex bake fixture (overlay2 OK, **3 mounts**, FATAL 0, exclusions 0, 618 MB, upload **201**, `GOLDEN_SHA256=b760ac6a33e70700…`, token-leak grep 0, GL-1 teardown, `drill.qcow2` back to `virgin`). Three observables: **published** — anonymous GET (what the installer does) 200 / 648930639 bytes / sha identical to the bake; **vouched** — manifest read BACK; **resolved** — `Artifact manifest served for customer sess-f (agent=0.116.0 golden=0.186.0)`. Floor **untouched** per publish-train rule 2 (`min_controller_version` still 0.156.0; it is a separate form); MinAgent left 0.113.0 as 0.186.0 declares. **Proven on a REAL day-0, not the fixture** (per the Part-1 rule now in `runbooks/target-selection.md`): VM 9402 on demo-hp from the v1.25.0 ISO → `Controller elindult (0.186.0)`. With the target detached the endpoint returned the **`TargetAbsent`** copy — *„A rendszermentés meghajtója nem érhető el — amíg vissza nem csatlakoztatod…"* — **and `offer_path` absent entirely**; the day-old read on the 0.185.1 golden had returned the false system-disk message **plus** an offer of the other drive. **Half 2 — the mechanism, operator ruling REFUSE.** hub **v0.82.0**: the gate sits in `hub/internal/web/configs.go` `handleSetArtifacts` immediately before the only write — the sole UI path to `SetArtifactManifest` — so it runs on every vouch without anyone choosing to, and it **refuses** rather than warning. Signal: `store.NewestReportedControllerVersion()` over `reports.controller_version`, **semver-compared in Go** (`MAX()` in SQL ranks 0.99.0 above 0.186.0 — a pair this fleet has shipped). Fail-open in exactly two deliberate cases: empty golden field, unknown fleet version. **NEAR-MISS RECORDED: the first draft read `guests.controller_version`, a column that exists and that NOTHING writes** — it would always have seen `""` and failed open, i.e. inert, this gate's own failure shape, one grep from shipping. 4 tests through the **production handler** over httptest (never a seam), the refusal asserting **both** the flash **and** that the manifest was not written; red-proof: deleting the block makes the stale golden vouchable again. **PROVEN LIVE on the deployed hub by re-attempting the original mistake:** vouching 0.185.1 → `HTTP 303 …flash=golden_behind_fleet` + `[WARN] artifact vouch REFUSED: golden 0.185.1 is older than the newest controller the fleet reports (0.186.0)`, and the manifest read back **unchanged at 0.186.0**. Recorded on **R-29's audit list** (`ROADMAP.md`) as the **first enforced gate** beside its three orphans, so the contrast is kept — the orphans are unchanged. Teardown all 3 layers; hub layer gate-blocked on ONLINE with the command recorded, exactly as `sess-e` was (and `sess-e` was deleted this run) | — |
| **R-117** | ~~**A drive's guest bind becomes a DEAD MOUNT while every signal reads healthy — and it happens in TWO ways, only one of which the original framing covered.** (a) *after a detach/return*: the host raw mount heals onto the NEW device via its fs-UUID-keyed unit while the bind still names the OLD one, so the gate takes its `Return` branch and restarts the customer's apps onto a namespace that `EIO`s on every call; (b) *in STEADY STATE, no cycle at all* — a device that errors without disappearing leaves the raw mount `active`, `BoundUnderParent` `true` and the drive never `Disconnected`, so **the gate produces no action and NOTHING is emitted on any channel**~~ | **SHIPPED + PROVEN-LIVE** (agent **v0.117.0**, 2026-07-30) | — | **CLOSED. `audits/R117-v0117-2026-07-30.md`.** `BoundUnderParent` gains a THIRD term at both /disks sites: `bindLiveness` reads `/proc` only and requires (a) **the bind names the same device as the raw mount** and (b) **the filesystem has not aborted** (`shutdown` **or** `emergency_ro`, both measured). **BOTH CHECKS ARE LOAD-BEARING and this is the substantive part:** R-117 was filed as a detach/return defect, but a device that fails WITHOUT disappearing gives the identical all-signals-healthy state with the **devnos EQUAL** and the drive never `Disconnected`, so the gate emits nothing at all, indefinitely (R-117a) — the device comparison alone cannot see it, and a P1-only fix passes every payload test (red-proof RP3 exists for exactly that). **THREE states, never a bool:** `{Unknown, Live, StaleDevice, Aborted}`, `Unknown` is the zero value, and every caller reads `Usable()` where unknown counts **PRESENT** (absent stops a customer's apps — the `newestArchiveOn` trap). **NO NEW RECOVERY PATH:** `AttachDrive`'s normalize leg already did the repair and three call sites already invoked it (20 s ticker, agent startup, and **the controller's `Return` branch BEFORE `restartStacks`**); all three were defeated by `if n == 1 && GuestSeesMount(...)` logging *"fully live, no-op"* about an EIO namespace. **RULING (asked for, given, flagged for overrule):** `StaleDevice` ⇒ **re-bind** (the raw mount is a healthy new superblock; repairs live, guest never restarts — init PID identical); `Aborted` ⇒ **quiet no-op and SURFACE**, because a re-bind lands on the SAME dead superblock and this runs every 20 s = an infinite silent retry that masks the state. No operator decision required: it routes an already-broken state into the **existing** gate, event types and Hungarian copy — no new customer-facing concept — and the alternative is apps writing documents into a filesystem that rejects every write. **ORDERING TRAP caught by a test:** abort-first classifies the real return state as aborted (its stale bind carries `shutdown` too) and refuses the repair **while still reporting correctly**, so the abort flag is read off the RAW mount in the stale case. **LIVE on demo-hp** (brought 0.113.0 → 0.117.0 first — see R-121): RETURN `raw 8:32 / bind 8:16 shutdown` ⇒ `stale-device`, usable **false**; IN-PLACE `both 252:11 emergency_ro`, raw unit still `active` ⇒ `filesystem-aborted`, usable **false**; healthy ⇒ `live`; **340–497 µs**. **No block I/O proven by strace** (only `/proc/self/mountinfo`, **0** statfs) — the Part 1 `CLAUDE.md` fence applied to its own first consumer. **No regression through the REAL pipeline:** `GET /disks` with the controller's own credential shows the live backup-target drive `bound_under_parent=True`, with 32 gate lines in 3 min as the positive observable and zero spurious transitions. Tests **849→863**, 29/29 green, **6 red-proofs each verified to land** — and **RP1 failing to fail exposed a HOLLOW test**: the aborted fixture used a `/dev/mapper` device, for which `RoleForStorage` derives `role=system`, and a system row never runs the conjunction, so it reported false by DEFAULT and no mutation could fail it. Fixtures now assert the production row shape first. Teardown all 3 layers; hub layer = the vouched manifest, **retained** (it is the product, not scratch). **NOT covered:** the stale-bind repair on hardware — `StablePathForRaw` hardcodes the live parent, so it would write into guest 9201's namespace (R-117h); and sustained-load behaviour, still unmeasured. Follow-ups **R-117g** (no guided recovery for an aborted fs), **R-117h** (parent dir not test-seamable), **R-121** | CC |
| **R-121** | **A BOX's installed agent can sit releases behind the vouched one and nothing notices — the R-120 gate does not cover it.** demo-hp ran agent **0.113.0** while the hub vouched **0.116.0**, through the whole R-116/R-117 arc, and no signal existed on any channel | **READY (S) — NEW 2026-07-30** | — | **Fourth instance of the drift family** (R-111 golden's agent 17 releases behind, R-115 built+deployed but never published, R-120 golden a controller behind — and now installed-vs-vouched on a live box). **Confirmed at source that R-120's gate cannot catch it:** `hub/internal/web/configs.go:1165-1169` compares `goldenVer` against `store.NewestReportedControllerVersion()` — it is a **golden-artifact vs fleet-CONTROLLER** check and says nothing about the agent installed on a box. **`MinAgent` does not cover it either:** it is used to HOLD the controller floor for a box whose agent is too old (`hub/internal/api/handler.go:530-538`, `store.go:1857`) — protective, not an alarm — and demo-hp's 0.113.0 **equalled** `min_agent` 0.113.0, so even a floor comparison was satisfied. **The cost, measured:** R-117's whole subject is the R-113 conjunction, which landed in **0.114.0** — so the designated drill host could not exercise the code under investigation at all, and the R-117 spike had to route every predicate result through an out-of-repo probe built from `main` instead of the installed agent (`audits/SPIKE-r117-bind-liveness-2026-07-30.md` §1, §2.3). Discovered because the R-117 task made bringing the box current an explicit prerequisite. **Fix shape (not implemented):** the hub already receives `AgentVersion` on every host report, and already has semver comparison in Go — the missing piece is a checker comparing reported agent vs the **vouched** agent and surfacing it, operator-tier. Note the honest tension: a box legitimately lags between publish and deploy, so this wants a staleness window rather than an instant alarm | CC |
| **R-118** | **An absent drive's union row advertises the ROOT filesystem's capacity as its own.** In the absent-state payload the registry-union row reports `total_bytes: 49675956224 / used_bytes: 4584579072` — **byte-identical to the `local` row** (`durable_id: path:/var/lib/vz`, i.e. `pve-root`) in the same response. The real drive is **4 GB** | **READY (XS) — NEW 2026-07-30** | — | Cause: `statfsCapacity(d.MountPath)` (`disks.go:335-338`) statfs's `/mnt/cel`, which with the device gone is a **bare directory on the root filesystem**. `observe.go:176-183`'s comment warns about exactly this trap and guards the Observe path ("*an unmounted removable dir-storage's mountpoint reverts to a bare directory on root … catastrophic DR mis-id*"); **the union path has no equivalent guard.** **Not a DR mis-id** — `durable_id` on that row is still the correct `uuid:…`, so re-attach identity is safe. It is a **false capacity** reaching every consumer of `total_bytes`/`used_fraction` (fill monitors, storage cards): a detached 4 GB drive advertises 46 GiB at 9.2 % used. Same class as `role.go:180-181` — an absent drive's fields decaying to the root filesystem's. Evidence: `audits/DIAG-r116-disks-payload-2026-07-30.md` §12 | CC |
| **R-113** | ~~**The drive-absent gate CANNOT FIRE on device loss — E-2b's alarm is wired to an unreachable condition.**~~ `planDriveGates` (`intermediary.go:216-262`) computes presence by OR-ing `d.BoundUnderParent` into `present[GuestPath]`, and the agent derives `BoundUnderParent` from `GuestSeesMount()` — *"is this path a mount target in the guest's `/proc/<pid>/mountinfo`"* (`localapi/disks.go:210`). The raw drive mount is a **device-bound systemd unit** and dies with the device; **the agent's own bind under the shared parent is NOT device-bound, so its mountinfo entry outlives the device**. The gate reads the surviving bind as "present" ⇒ no `Stop` action ⇒ `notifyDriveAbsent` never called | **SHIPPED + PROVEN-LIVE** (agent v0.114.0, 2026-07-29) | — | **PROVEN LIVE `audits/SESSION-C-2026-07-29.md`.** Target drive hot-detached on a fresh box running the SHIPPED agent 0.114.0 (from the Day-0 manifest, not a hand build). **The gate fired in 4 seconds** — E-2d measured ZERO over 4½ minutes — and `SetDisconnected` was reached. It fired on exactly the shape that defeated it: raw `/mnt/mentes` NOT mounted while the bind `/mnt/felhom-drives/mentes` still read `/dev/sdb[/felhom-data]`. **Over-correction guard PASSED:** with both drives present, 0 ABSENT lines and the target stayed healthy. **Note: C5 still FAILED — but on a different defect (→ R-116), not on this one.** **SESSION C IS NOW UNBLOCKED.** Agent **0.114.0 published and vouched** 2026-07-29 (sha `5e4c15ebee2d7583…`, round-trip GET verified; hub manifest read back showing it) — a fresh drill box now installs the fix under test instead of the bug. The golden was NOT re-baked and `min_agent` was NOT raised: the golden bakes the controller, not the agent, and controller v0.185.0 declares MinAgent 0.113.0, which 0.114.0 already satisfies. **FIX: `BoundUnderParent` is now a CONJUNCTION — bound under the parent AND the drive's raw host mount still mounted** (`devicePresent`, new `deviceCheck` seam), at BOTH `/disks` construction sites. The raw mount is the device-bound systemd unit that dies with the device; the agent's bind is not — so the raw mount IS the device signal, grounded in E-2d's measurement rather than inference. **Conjunction, deliberately:** the device half alone would regress boot ordering (raw mounts early, bind lands ~18 s later — that window must keep reading absent), so existing behaviour is byte-identical and only the unreachable case is closed. **Unknown is never absent** (`devicePresent("")` = true) — a false absent stops a working customer's apps. **Controller UNCHANGED, no MinAgent bump:** `BoundUnderParent` has exactly one functional consumer (`planDriveGates:226`); a new `DevicePresent` bool was rejected because absent-from-JSON decodes to `false`, which would have made every drive on an older agent read ABSENT. +6 tests (208→214), 4 red-proofs run and reverted. **Deployed to demo-felhom; over-correction guard verified in production** — raw mount present, drive still reads present, 10/10 apps untouched, no gate action, no false alarm. **demo-hp deliberately left on 0.113.0** (the spec scoped deploy to felhom-pve) — it still carries the bug. **⚠️ SESSION C BLOCKER: the hub Day-0 manifest vouches agent 0.113.0**, so a fresh drill box would install WITHOUT this fix and validate nothing — publish + vouch 0.114.0 first (R-111's trap, same shape). **Awaiting live proof of exactly one leg:** device loss → gate `Stop` → `SetDisconnected` → `backup_target_absent` on the wire. Original finding: **PROVEN LIVE 2026-07-29 on a fresh box.** Target drive hot-detached under a running agent; over 4½ min (budget was 60 s): the **agent** said `enrolled drive absent by UUID` every 20 s, the controller logged **0** `[gate]` lines, and the hub received **zero** events — no `backup_target_absent` **and no generic `storage_disconnected`**. Measured with the device gone: `/mnt/mentes2` NOT mounted, `/mnt/felhom-drives/mentes2` still `/dev/sdb[/felhom-data]`. **Not a virtualisation artefact** — the asymmetry is device-bound-mount vs manual-bind, identical on metal (caveat: proven on SCSI hot-detach; physical unplug not staged). **Mirror scenario reasoned, not observed:** both the specific and generic events come from the same `a.Stop` branch, so the generic one is equally unreachable. **Sixth instance of seam-built-but-never-wired** — E-2b wired the seam, to a condition that cannot occur. Evidence: `audits/E2D-fresh-vm-2026-07-29.md` §5.2 **Session C scope UNCHANGED by Session B** — R-114/R-112 shipped as controller v0.186.0 and neither touches the agent; the leg awaiting proof is still device loss → gate `Stop` → `SetDisconnected` → `backup_target_absent` on the wire. One rebuild now validates all three. | CC |
| **R-112** | **E-2's degraded banner and offer have NO UI CONSUMER — the endpoint is correct and the customer never sees it.** `GET /api/storage/backup-target` returns byte-exact copy (proven live), and **nothing fetches it**: `grep 'backup-target'` across all `*.html`/`*.js`/`*.css` → **0 hits**; no template references `OfferPath`/`Degraded`/the copy; `resolveBackupTargetState` + `degradedMessageFor` are consumed **only** by the JSON handler — **no page handler injects the state** | **SHIPPED + PROVEN-LIVE** (controller v0.186.0, 2026-07-29) | — | **PROVEN LIVE `audits/SESSION-C-2026-07-29.md` — the banner reached a customer's page for the first time.** Never-configured box: banner element 1, never-configured copy 1. After the wizard: offer block 1 with `data-path="/mnt/felhom-drives/mentes"`. Healthy after assign: all four markers 0, **proven POSITIVELY** — idle delta 0 `/backup/tiers` calls, page-load delta +1, single caller ⇒ the seam ran and chose silence. **FIXED: the state now has a consumer.** Server-rendered on `/backups` via `backupsHandler` → `backupTargetView` → `backups.html`, following the existing `SingleCopyWarning` banner pattern — NOT a 19th JS fetch, because a banner that needs JavaScript to appear is one more thing that can silently not happen. `backupTargetView` returns **nil** for healthy AND unknown, so those render nothing at all. **Scenario-E seam test drives `backupsHandler` over httptest and asserts the RENDERED HTML** — deleting the one line that sets `data["BackupTarget"]` reproduces the old state and fails every render assertion. **SEAM PROVEN LIVE on demo-felhom by a DIFFERENTIAL positive observable, not by an absent banner:** idle 8 s → 0 new `/backup/tiers` agent calls; each `/backups` load → exactly +1, and that call has only one caller (`resolveBackupTargetState`). The box is healthy (`degraded:false, target:felhom-backup`) and the page correctly rendered **nothing** — which matches its real state but, being a negative, is NOT by itself proof of wiring. **Still unproven live:** that a customer sees actual copy — impossible on a healthy box. **The decisive contrast: templates fetch 18 distinct `/api/storage/*` endpoints; `backup-target` and `backup-target/assign` are the only two with zero references.** The handler's own comment calls itself *"the dashboard's source for the degraded banner and the offer"* — an invariant comment asserting a consumer that does not exist (7th instance of that class). v0.185.1 shipped as *"the offer endpoints were mounted where nothing routed to them"* — it fixed the **router mount** and stopped one layer short of the **render**; its test `TestBackupTargetRoutesLiveUnderTheStorageAPIMount` pins dispatch, not reachability, which is exactly what `CLAUDE.md`'s seam rule warns about. **Fifth instance of seam-built-but-never-wired.** **Fix R-114 FIRST** — wiring this alone would start showing customers the wrong message. Evidence: `audits/E2D-fresh-vm-2026-07-29.md` §5.1 | CC |
| **R-114** | **On target-drive loss the customer is told the wrong story and offered the drive that just vanished.** With the assigned target absent, the endpoint returned `degraded:true, target:"felhom-backup"` **plus** the *"a rendszermentés ugyanazon a lemezen van, mint a rendszer"* message — false, the target is a drive that has disappeared, not the system disk — **and** `offer_path` pointing at the missing drive as the remedy | **SHIPPED + PROVEN-LIVE** (controller v0.186.0, 2026-07-29) | — | **PROVEN LIVE `audits/SESSION-C-2026-07-29.md`.** With the target absent the page rendered the ABSENT copy (1), the system-disk copy 0, the offer block 0 — both of E-2d's falsehoods gone. API carried `message:"A rendszermentés meghajtója nem érhető el…"` with `target:felhom-backup`. **FIXED: the third state exists.** New `BackupTargetState.TargetAbsent` separates *configured-and-gone* from *never-configured*. `Degraded` keeps its meaning (is there a problem) so the wire contract is unchanged for every consumer; `TargetAbsent` answers which problem, because the remedies are OPPOSITE — attach any second drive vs reconnect *that* one. Copy routed through `degradedMessageFor` (still one decision point) and taken **verbatim** from the hub's `backup_target_absent` email so banner and mail tell one story. **Offer suppressed on the branch itself**, deliberately not left to `firstOfferableDrive`'s `Disconnected` skip — that flag is set by R-113 in another repo, and this state must be right without it. Red-proof: deleting the branch reproduces E-2d's exact payload, offering `/mnt/felhom-drives/mentes2`, the drive that had vanished. **MinAgent unchanged 0.113.0** — R-114 reads `BackupTarget`/`MountPath`/`GuestPath`/`Role`, none of which R-113 altered, so demo-hp is not held. **NOT live-validated: Scenario C cannot occur on a healthy box.** `resolveBackupTargetState` falls through to the generic degraded branch whenever no disk satisfies `d.BackupTarget && d.MountPath != ""`, never distinguishing **never configured** from **configured and now missing**. Shares R-113's root cause — two disagreeing presence signals — but is a different code path with a different fix. **Currently invisible ONLY because of R-112; fix this before wiring that.** Also seen: after reattach the drive returned as `/dev/sdc` while the stable bind still recorded `/dev/sdb`, and the state read healthy.

| **R-29** | **The green gates are not enforced anywhere — one was RED for 16 releases before anyone ran it.** This is the **class**, not an instance: a gate that exists, asserts something true, is red, and is invoked by nothing reads as coverage it is not providing. `controller/scripts/docker_run_volume_path_gate.py` failed continuously from **2026-07-14 (v0.129.0)** until R-7b's close-out ran it by hand at v0.145.0 — sixteen releases in which every REPORT said "green" | **READY (S for (a) / M for (b))** | — | **This item has existed at `ROADMAP.md:158` since before the register was rebuilt (2026-07-27) and was never carried across — that omission is itself part of the finding**, because it is an open item *about work not getting done* that then went missing from the page that decides what gets done. Two separable parts, per R-29's own analysis: **(a)** the `docker_run_volume_path_gate` finding is benign and the fix is a 3-line ALLOWLIST addition with its why — **not** a rewrite of the flagged call — and it gets its own reviewed diff, never bundled into a feature commit; **(b)** the systemic half, the real item: decide where gates run (pre-push hook, `build.sh` step, or CI) and make a red gate block the train the way the Go green gate does. **Two further orphans confirmed 2026-07-29** by repo-wide grep across all file types + sibling repos + `~/.claude` settings/skills/hooks + `.git/hooks` (none non-sample) + Makefile/justfile/Taskfile find (only `hub/Makefile`, zero `gate` occurrences) + CI-directory find (**this repo has no CI at all**) — every one of the 19 hits is a docstring, a code comment or prose, and **not one is an invocation**: `scripts/hostinstall_gates.py` — **RED today** (`hub Setup-tab hostInstallVersion=1.19.0 != SCRIPT_VERSION=1.22.0`, exit 1), the same finding as **R-94 leg (b)** — and `scripts/hub_confirm_gate.py`. Of the four gates in `scripts/`, only `site_gates.py` is mandated anywhere (`CLAUDE.md:153`) and `manifest_bearer_gate.py` is named in `runbooks/secrets.md:76`. **In R-29's own words, carried forward deliberately: do not mint a new ID for a new instance** — the 2026-07-18 rehearsal independently re-raised this item and no second ID was minted then either | CC |

Installer is ~~installer-logic-tested, not install-tested~~ — **INSTALL-TESTED 2026-07-29** on a fresh nested box via the real ISO/PAIRING route, rc=0 (`audits/E2D-fresh-vm-2026-07-29.md` §3). **Of the "NOT yet live-proven" list: Case B + the degraded state are now PROVEN at the installer and API level; the OFFER ACCEPTANCE is PROVEN at the API level** (decline path, `restart_required:true`, E-2a wrapper, healthy-renders-nothing). **Still NOT proven, and now known to be BROKEN rather than merely untested:** the banner/offer never reach a customer (**R-112**) and `backup_target_absent` cannot fire on device loss (**R-113**), with the absent-state message itself wrong (**R-114**) | CC |
| **E-2a** | ~~The target move needs a root-fenced wrapper — the agent cannot do it~~ | **SHIPPED + PROVEN-LIVE** (agent v0.113.0 + host-install v1.22.0, 2026-07-29) | — | `felhom-backup-target-apply` behind a literal `FELHOM_BACKUPTARGET` sudoers alias; the agent's PVE role was NOT widened. Enforces F-1 (`mountpoint -q`) and F-2 (`is_mountpoint 1` hardcoded), refuses a root-device target, has NO storage-removal path (grep-assertable), is idempotent and refuses to repoint. All five laws proven live as root on demo-hp with 0 stray storages | — |
| **E-2b** | ~~`NotifyStorageDisconnected`/`Reconnected` defined and called NOWHERE — a drive going absent emitted no event on any channel~~ | **SHIPPED + PROVEN-LIVE** (controller v0.184.1 + agent v0.112.0 + hub v0.81.0, 2026-07-29) | — | Seam wired in `ReconcileDriveGates`; a target drive raises the specific `backup_target_absent` instead. **A keying bug was caught before deploy:** `a.Path` is the registered GUEST path, not the agent's host `MountPath`, so the target branch was unreachable — every absent drive, target included, fell through to the generic event (v0.184.1). Tests observe the WIRE (httptest hub), not a mock | — |
| **E-2c** | ~~E-1 put the whole-guest backups on a drive `POST /disks/eject` would eject~~ | **SHIPPED + PROVEN-LIVE** (agent v0.112.0, 2026-07-29) | — | Eject + decommission refuse 409 on the backup-target mount, naming the storage and the remedy. **Live on BOTH boxes:** demo-hp `/mnt/nvme-1tb` and demo-felhom `/mnt/hdd_1` both refused, drives unmoved. NOT a role reclassification — `RoleForStorage` untouched, because on both boxes that drive is ALSO the enrolled user-data drive; `TestEjectStillAllowedOnANonTargetDrive` pins the non-over-correction and `/var/lib/vz` is still refused by the PRE-EXISTING role gate, not this one | — |
| **PETI** | **`peti-felhom` deliberately NOT migrated.** Its whole-guest backup still shares a device with its guest, so a drive failure there is **offsite-only recovery** | **ACCEPTED RISK — parked** | operator's next visit (tester reinstalling from scratch) | **Accepted until the reinstall; re-evaluate if that slips past ~2026-09-01.** Do not migrate, do not touch | operator |
| **R-109** | ~~The DR recipe records no backup target~~ | **SHIPPED + PROVEN-LIVE** (agent v0.118.0 + hub v0.83.0, 2026-07-30) | — | `backup_target` resolves from the PRIMARY tier of `cfg.Backup.BackupTiers()` — the function the scheduler consults, not a re-derivation — plus the mountpoint, which is what actually separates `/mnt/hdd_1` from `/var/lib/vz`. Three states, and unresolvable is recorded as unresolvable (`agent_backup_config_unavailable` / `not_a_known_storage`), never a default. **The resolver reads the daemon-start config on purpose:** a target move rewrites `agent.json` and deliberately does NOT restart, so a disk re-read would name a storage no archive had reached. **Needed a HUB half nobody had scoped** — `AssembleDRRecipe` allow-lists top-level keys, so the field would have been stored intact and dropped before any operator saw it (→ **R-122**). Evidence: `audits/R106-R109-recipe-completeness-2026-07-30.md` | — |
| **R-106** | ~~The DR recipe records the PBS namespace as `"root"` on every box~~ | **SHIPPED + PROVEN-LIVE** (agent v0.118.0, 2026-07-30) | — | **Was open-but-UNREGISTERED on this page until 2026-07-30 (→ R-123)** — `ROADMAP.md:109` had it READY and the only mention here was inside R-109's prose. Namespace now resolves from the pbs STORAGE (storage.cfg's `namespace`), the same field `vzdump --storage <pbs>` makes PVE read, so the recipe cannot disagree with the backup that produced the snapshot. An unconfigured namespace still reads `"root"` — that is an ANSWER, and `namespace_state` separates it from not knowing. Live: `demo-felhom` and `demo-hp` now report their own namespaces. Evidence: same audit | — |
| **R-122** | ~~`AssembleDRRecipe` silently DROPPED `offsite_restic` — the offsite recovery location never reached any recipe~~ | **SHIPPED** (hub v0.83.0, 2026-07-30) | — | **Found 2026-07-30 while scoping R-109's hub half; it had already shipped and nobody knew.** The controller has emitted `offsite_restic` since fork-4 (*"so DR knows WHERE to recover from"*), the hub stored it for **all three real customers**, and `appHalfShape` never listed the key — so no delivered recipe has ever contained it. No error, no log, green suite, because the fixture `drAppHalf` is hand-written and omits the field. `hostHalfShape`/`appHalfShape` are **ALLOW-LISTS dressed as forward-compat**; `TestAssembleDRRecipe_CarriesEveryEmittedSection` is now the guard, built on halves read verbatim out of the live `dr_recipe` table. `REUSE.md` (both repos) records that a recipe section is a TWO-REPO change | — |
| **R-123** | **R-105 and R-106 were `READY` in `ROADMAP.md` with no row on THIS page** — each referenced only inside R-109's prose, which is precisely the thread-loss the register exists to prevent | **PARTLY CLOSED** (2026-07-30) | — | R-106 registered above (and shipped). **R-105 still needs a row** — it is M-sized, is about three hub-held DR records being `{}`, and is NOT part of the recipe-completeness set that shipped today. **The process gap is the real item:** nothing checks that a `READY` ROADMAP row has an OPEN-ITEMS row. A grep-level gate would catch it | CC |
| **R-124** | **The recipe spells PBS's root namespace `"root"`, but the PBS API spells it `""`** and no namespace is literally named `root` — an operator pasting the field into `pct restore --ns root` gets a failure | READY (XS) | — | Pre-existing wire convention (`ToHub` has normalised empty→`"root"` since slice 6), deliberately NOT changed under R-106 so the field's meaning did not shift mid-fix. Documented at `hub.PBSRootNamespace`. Affects only a box with no `namespace` line — **no real customer today**, all three are per-customer. Fix = emit `""` + rely on `namespace_state`, or emit a `--ns`-ready form | CC |
| **R-89** | Retention as a per-customer **commercial** policy on the hub | READY (increment 2) | — | Policy object + reconciler → ep0 prune job; keep box tokens write-only | CC |
| **R-92** | Hub PBS-DR gauge is 0.1 GB-granular — small deltas unverifiable | READY (XS) | — | Widen precision when retention becomes customer-visible | CC |
| **R-93** | `drill-r50` is both a blocked customer and the only drift fixture | READY (XS) | — | Retire it for a synthetic fixture, or unblock + silence per-customer | CC |

## Why the TOP READY rows rank this way

This covers the next few only — it is deliberately **not** a full ordering of the table above, so that
there is one ranking to maintain rather than two.

1. **R-95** — the largest *data* exposure: the tier holding the customer's documents and photos is the
   one whose credential can delete. The snapshot mitigation is now **armed** (daily 00:00, keep 7),
   but it has taken zero snapshots so far and it does not touch the root cause — the box can still
   `forget --prune` its own repo.
2. **R-94** — **de-ranked 2026-07-29.** The prior rationale ("until it moves every hub-driven
   install gets the pre-R-82 default") was false: the constant selects no script and every install
   already fetches 1.22.0. What remains is a wrong label plus two pieces of dead safety equipment —
   a drift gate nobody runs and a test that compares a constant to itself. Cheap and worth doing;
   not high-consequence, and it blocks nothing.
3. **R-86** — an operator ruling already exists; it only waits on knowing what load ep0 can take.
4. **R-87** — real and unbuilt, but needs its own design, so it should not jump work that is specified.
5. **R-110** — last **because it is not a READY row**: the ruling is the operator's, not CC's, and
   there is nothing for CC to build until it lands. Ranked here rather than omitted because it is the
   only item on this page about the *publish channel* of the most privileged artifact Felhom ships,
   and today's exposure is zero — which makes now the cheapest moment it will ever be to decide.
