register: file R-156..R-164 in one pass, ranked; and record what mp1 is actually for

Nine rows into OPEN-ITEMS.md and ROADMAP.md, matching each file's column shape.
R-156 and R-157 had lived only in audit documents - the identical "minted in a
spike doc and never carried across" failure the register already records for
R-153/R-154/R-155, caught by the catalog sweep's own section 8.0 while it was
happening. R-158 was minted by a second session the same day for an unrelated
finding, which is why the sweep's proposals were renumbered R-159..R-162 at filing
time. All nine IDs verified free in BOTH backlog files before use.

Part 0 settled the question the sizing item depended on, by reading:

mp1 is RETENTION, not staging, and neither of the two framings was right. A unit
is the KEPT copy on the app's OWN drive (backup.go:245-255); for an app with no
HDD_PATH the namespace falls back to the system SSD - "the SSD-only system-data
fallback" (appbackup/paths.go:26-27). There is no post-copy deletion: the only
prune is F5 residue-on-old-drives when an app MOVES (backup.go:1053-1112). So mp1
retains the units of driveless apps only - not every app, but not transient
either. Confirmed against the spike: sys_drive held exactly the four driveless
apps and not calibre-web, which had a drive and was still backed up.

A unit is volume tars + DB dumps only, never mp8 userdata
(recovery_unit.go:20-25), so a 1 TB photo library can never overflow one. And mp1
gates the WHOLE chain, not just Tier 1: Tier-2 mirrors the unit "(always)" from
RecoveryUnitPath (tier2.go:302,368) and Tier-3 carries it, so a unit that cannot
be written leaves both with nothing to copy.

Part 2 fired on both triggers - retention, and the fallback undocumented - so
07-backup-architecture.md gains section 7.5. Section 6.1 said a unit lives "on the
app's own drive", which is true and was the whole story only for drive-resident
apps; the no-drive case was undocumented, as was the sizing constraint. 7.5
records the mp0-50G-vs-mp1-20G mismatch, the measured ratios (DB app up to ~2x,
21.1GB -> 40.2GB; file-only 1.00x), and the bound this puts on D5's Lane-1
independence: restorable from the drive alone only while the unit still fits -
about 19 GB file-only, about 10 GB DB-backed. No number proposed; the ratio is the
operator's ruling (R-163).

R-159/R-160 marked SHIPPED only after verifying the template changes are in
app-catalog origin/main, and R-156's gate likewise (check-volume-persistence.py
present). papra is NOT fixed - referred - so R-156 stays open on that one app.

Ranked, with one line of reasoning each: R-157 first (an app can stay down
indefinitely with mechanism B silent on every channel), then R-161 (the gate
exists and nothing runs it, which is why R-156's class recurs - R-29's record is
three orphaned gates and one enforced), R-156, R-163, R-158, R-164, R-162.

### 7.5 Where a recovery unit is RETAINED — and the size bound it puts on Lane 1
Added 2026-08-02 from `audits/SPIKE-recovery-unit-space-2026-08-02.md` and
`audits/CAMPAIGN-10-closeout-2026-08-02.md`. §6.1 says a Tier-1 unit lives *"on the app's own drive"*,
which is true and is the whole story for a drive-resident app. **It is not the whole story for an app
with no data drive, and that case was undocumented until now.**
**The unit is RETAINED, not staged.** `GetAppDrivePath` (`felhom-controller/internal/backup/backup.go:245-255`)
returns the app's `HDD_PATH` if it has one and **`systemDataPath` otherwise** — what
`internal/appbackup/paths.go:26-27` calls *"the SSD-only system-data fallback"*. Nothing deletes a unit
after it is copied onward: the only prune is F5 (`backup.go:1053-1112`), which removes residue on an
**old** drive when an app **moves**. So for every app without a data drive, `mp1` holds the kept copy
indefinitely.
**What a unit contains, which bounds the problem** (`internal/backup/recovery_unit.go:20-25`):
`compose/` + `db-dumps/` + `volume-dumps/` (named-volume tars) + `manifest.json`. **It never contains
`mp8` / `HDD_PATH` userdata** — a photo library on a 1 TB drive is not in a unit, and cannot make one
overflow.
**The resulting mismatch, on a default appliance:**
| | size | holds |
|---|---|---|
| `mp0` `/var/lib/docker` | **50 G** | every app's live volumes — the thing a unit copies |
| `mp1` `/mnt/sys_drive` | **20 G** | the retained units of every **driveless** app |
A DB-backed app's unit is up to **~2×** its data, because it carries the volume tar **and** the SQL
dump (measured: 21.1 GB of app data → a **40.2 GB** unit). A file-only app's is **1.00×** (measured:
homebox 2305 MB → 2305 MB). `--sysdata-grow` (`felhom-agent/cmd/felhom-agent/main.go:178`) defaults to
**0**, is not derived from the physical drive, and no observed box passes it — demo-hp's production
guest 9201 ships `mp0 50G / mp1 20G`.
**`mp1` gates the entire app-data chain, not just Tier 1.** Tier-2 mirrors the unit *"(always)"* from
`RecoveryUnitPath` (`internal/backup/tier2.go:302,368`) and Tier-3 carries it too, so a unit that
cannot be written to `mp1` leaves Tier-2 and Tier-3 with nothing to copy.
**The bound this places on Lane 1 (§3).** Lane 1's promise is that a customer can restore an app from
the drive alone, without the operator and without the guest — D5 (§7.4) made that true by putting the
portable secrets in the unit. **That independence is bounded by app size**, and the bound is:
> On a default appliance, an app can be restored by Lane 1 only while its recovery unit still fits the
> retained space — **≈ 19 GB of app data for a file-only app, ≈ 10 GB for a DB-backed one.**
> Past that the unit cannot be captured, and the app falls back to Lane 2's operator-driven
> whole-guest route.
Two things are deliberately **not** recorded here. **The sizing ratio is the operator's ruling**
(**R-163**) — this section states the constraint, not a number. And **the same-device placement is
intended, not a defect**: a driveless app's unit sits on the same SSD as its volumes, but Tier-2's
cross-drive mirror, the whole-guest tier (which covers `rootfs + mp0 + mp1`, §6.1) and Tier-3 all cover
device loss. What was missing was that this case existed at all, and that nothing warns when an app
crosses the line — **R-158**.

There is **no post-copy deletion**: the only prune is F5 (`backup.go:1053-1112`), residue on OLD drives when an app MOVES.

Bounded on the other side: a unit holds **volume tars + DB dumps only, never `mp8` userdata** (`internal/backup/recovery_unit.go:20-25`), so a 1 TB photo library is never in one. **This bounds D5's Lane-1 independence** — see `architecture/07-backup-architecture.md` §7.5.

### The 2026-08-02 intake (R-156 … R-164), ranked
Filed in one pass from Campaign 10, its two spikes, and the 53-template catalog persistence sweep.
**R-156 and R-157 had lived only in audit documents** — the identical *"minted in a spike doc and
never carried across"* failure the register already records for R-153/R-154/R-155, caught by the
sweep's own §8.0 while it was happening. R-158 was minted by a second session on the same day for an
unrelated finding, which is why the sweep's proposals were renumbered to R-159…R-162 at filing time.
1. **R-157** — highest: a `deployed: true` app can stay **down indefinitely** after a power cut or
hard reset, and in mechanism **B** nothing reports it on any channel (`0 currently down`). It is the
only row here where the customer loses service and has no signal at all.
2. **R-161** — next, because it is why R-156's class **recurs**. The gate that convicts it exists and
nothing runs it; R-29's record is three orphaned gates and one enforced one, and only the enforced
one has ever stopped anything. Needs a ruling, not a task.
3. **R-156** — the class is now detectable and two of three apps are fixed; what remains is **papra's
referral**, one app, well understood.
4. **R-163** — a real ceiling that silently caps local backup once an app outgrows `mp1`, and it gates
Tier-2 and Tier-3 as well. Ranked below the above only because **overflow itself is safe today**
it refuses per app and preserves the last good unit byte-identical. Waiting on the operator's ratio.
5. **R-158** — the gap that makes R-163 dangerous: cross the size line and **one page** tells you. On
its own it is a notification gap, not a silent failure, which is why it sits here and not higher.
6. **R-164** — blocked on a predicate, no customer impact today; it only becomes urgent if the unit
size in R-163 is judged unacceptable, since the tar-drop is the cheapest way to halve it.
7. **R-162**`WATCHING` only. A limitation that fails closed; revisit if a non-overlay driver ships.
**R-159 and R-160 are SHIPPED** and are not ranked; they are filed to record the class, and R-159's
class (an image `VOLUME` at an unmounted path) is still live — `immich-server` has one today.

| R-159 | **wishlist's data landed in an ANONYMOUS volume — never backed up, orphaned by a redeploy** | XS | **SHIPPED** (`templates/wishlist/`, 2026-08-02) — filed for the CLASS | Image declares `VOLUME /usr/src/app/data`; template mounted `wishlist_data:/data`, a path the app never writes. `ResolveDockerVolumeNames` returns names only for compose-declared volumes, so `DumpAppVolumes` never sees an anonymous one. **The class is open:** any image `VOLUME` at an unmounted path is silent unbacked-up storage — **`immich-server` has one today** at `/data`, empty when measured. Proposed `REUSE.md` rule: a template mounts every path in `Config.Volumes`, or says why not |
| R-160 | **gramps-web persisted three paths and wrote to none of them** | XS | **SHIPPED** (`templates/gramps-web/`, 2026-08-02) | `/app/data` appears nowhere in the image's env; the accounts DB and **the family tree** (`GRAMPS_DATABASE_PATH=/root/.gramps/grampsdb`) both landed in the writable layer. Upstream persists **eight** paths, the template three, one a phantom. **Severity above papra's:** papra loses documents the customer may hold elsewhere; gramps-web loses the artefact built inside the app, of which no other copy exists by construction |
| R-161 | **The volume-persistence gate exists and nothing automated runs it** | M | BLOCKED — needs a ruling (operator, 2026-08-02) | Enforcement is **convention**: the catalog repo has no CI at all (`.gitea/workflows`, `.github`, drone/woodpecker — searched, none). **R-29's record: three orphaned gates, one enforced, and only the enforced one ever stopped anything.** Options, neither buildable from the catalog repo: Gitea Actions CI (nothing to build on), or controller-side at template load (`internal/stacks/metadata.go:336-358`) — which needs a runtime probe on a customer box and a ruling on what a failing sync does to a working app |
| R-162 | **`docker diff` is the gate's only witness and its failure mode is quiet** | XS | WATCHING — 2026-08-02 | A limitation, not a defect. The gate's power is `docker diff` excluding mounted paths; on a driver where it is unsupported or lies, the gate degrades to mount-occupancy + writability **and would not say so**. It fails closed (the canary self-test stops reporting BROKEN and the gate then refuses to report), but the message blames the prober rather than the driver. Revisit only if a non-overlay driver ships |
| R-163 | **`mp1` is RETENTION, not staging — and it is sized as if it were neither** | M | **WAITING-ON-OPERATOR** — the ratio is a tier-sizing ruling | Settled by reading: a unit is the KEPT copy on the app's **own** drive (`backup.go:245-255`), falling back to the system SSD for driveless apps — *"the SSD-only system-data fallback"* (`appbackup/paths.go:26-27`); **no post-copy deletion**, the only prune is F5 residue-on-old-drives (`backup.go:1053-1112`). So `mp1` **20 G** retains every driveless app's unit while `mp0` permits **50 G** of volumes, and a DB app's unit is up to **~2×** its data (measured 21.1 GB → 40.2 GB). `--sysdata-grow` defaults to 0 (`felhom-agent/.../main.go:178`), not derived from the drive; demo-hp's real guest ships 50G/20G. **`mp1` gates the whole chain** — Tier-2 mirrors the unit *"(always)"* (`tier2.go:302,368`) and Tier-3 carries it. Bounded: a unit is volume tars + DB dumps only, **never `mp8` userdata** (`recovery_unit.go:20-25`). **No number proposed.**`07-backup-architecture.md` §7.5 |
| R-164 | **C2's chain — the DB volume tar cannot be dropped until a sound dump predicate exists** | S | BLOCKED — on the predicate (2026-08-02) | The unit holds a volume tar **and** a SQL dump and the restore uses both: the dump is authoritative and replayed after the tar so it WINS (F17), with only the DB service up (R-47) — `restore_unit.go:262-266`. Dropping the DB tar would halve DB-app units and close R-127(b)'s initdb-skip trap. **The obvious gate is dead, measured:** `ValidateDump`'s empty-`accounts` warning was **correct** (the DB truly had 0 rows; seeding one stopped the warning and put the row in the dump) — but **a fresh appliance legitimately has zero accounts**, so gating on it blocks every new customer's first backup. Order: sound predicate (dump vs **live** per-table counts) → warn→gate → tar-drop. Pairs with **R-127** |
| R-90 | **ep0 has 3.8 GB and NO swap — it OOMs under a restore-test, and that gates R-86** | S | BLOCKED on Hetzner CX33 availability (operator, 2026-07-27) | Verified read-only: `Swap: 0B`, nothing in `/etc/fstab`, no swap unit, no `/swapfile`**swap was never added.** On 2026-07-27 06:58:12 a global OOM fired while `proxmox-backup-proxy` held a 3.2 GB peak serving a 14.46 GB restore-test read and the datastore-migration `rsync` held 1.9 GB; the kernel killed the rsync and PBS stopped serving for ~15 minutes. That outage is what exposed **R-88** downstream. Still exposed today: 3.8 GB, no swap, one kill on record. **This gates R-86** — backup-aligned restore-testing puts a multi-GB read on this box *on a schedule*, so the headroom question must be settled before that lands. Interim lever if CX33 stays unavailable: a swapfile, which needs no console |
| R-91 | **The old 13 GB datastore copy is still on ep0's root disk** | XS | WATCHING — gated on demo-felhom's first post-migration PBS backup | The datastore moved to a Hetzner Cloud Volume on 2026-07-27 (`/dev/sdb`, 100 GiB, attached 06:29:40 UTC, now `/mnt/pbs-datastore`, 13 G used of 98 G). The pre-migration copy survives at **`/srv/pbs-felhom`, 13 G**, on `/` (38 G total, 16 G used, 21 G free). **Do not delete yet:** demo-hp has landed two post-migration snapshots (07-27 08:25:47Z, 09:37:29Z) but **demo-felhom's newest is 2026-07-26T12:21:48Z — before the migration**, so the new volume has not yet proven a write for that namespace. Delete once it has. **Doc drift to fix in the same commit:** `CONTEXT.md:1018` still records the datastore at `/srv/pbs-felhom` |
| R-92 | **The hub's PBS-DR gauge is 0.1 GB-granular, so small deltas are unverifiable** | XS | idea — 2026-07-27 | The PBS-DR box card rounds to 0.1 GB, which is coarser than the changes an operator wants to confirm after a prune or a GC — a successful prune of a small namespace moves the number by less than one displayed digit, so the UI cannot distinguish "it worked" from "nothing happened". Cosmetic today; it becomes load-bearing the moment retention (R-89) is customer-visible and someone needs to see that a policy change took effect |
