docs: CAMPAIGN 7 catalog sweep — audit, ROADMAP R-40/41/42, REPORT convention

Adds the CAMPAIGN 7 audit doc (53/53 apps deployed and validated on the demo box
through the real controller endpoints; 45 pass, 13 template fixes, ranked
findings) and the uninstall-semantics map row it proves out: remove requires stop
first, named docker volumes are ALWAYS destroyed including the DB, HDD data and
backups survive unless explicitly ticked, and the per-app offsite toggle outlives
the app while tier-2 config is cleared.

ROADMAP +3:
  R-40 the update path cannot express a multi-hop major upgrade (nextcloud
       forbids skipping majors; the template moved 31 -> 34)
  R-41 no standing 'does every template still deploy?' check -- the sweep was
       the first thing to try, and found 5 apps that had NEVER been deployable
  R-42 ruling needed on DB/cache sidecar majors (deliberately not bumped)

CLAUDE.md: REPORT.md is overwritten, so a second concurrent session in this repo
writes REPORT-<topic>.md instead -- applied to this run's own report.

 | R-37 | **Post-RESET health card shows stale pre-RESET warnings.** After a RESET the card should read **„RESET óta nincs adat"** instead of carrying warnings about a lifecycle that no longer exists. | XS | **SHIPPED (hub v0.67.0, 2026-07-18)** | The customer page raises a banner when a RESET **completed** after the newest report, quoting „RESET óta nincs adat" and the reset timestamp, because until the box reports again every health figure describes a lifecycle that no longer exists. Deliberately narrow: an **in-flight** reset does not trigger it (only a completed one), and it **clears itself** on the first post-RESET report. Ties resolve to STALE — SQLite timestamps are second-resolution and a same-second report almost certainly arrived just before the reset destroyed what it describes; erring the other way would hide the banner exactly when it matters most. Red-proofed (neutering the predicate fails the assertion). — Origin: 2026-07-18 rehearsal. Same family as R-36 — the hub knows the state changed and the UI has not caught up |
 | R-38 | **Installer GRUB slice.** A single default „Felhom telepítés" entry; the **interactive installers REMOVED** (safety: an interactive entry is how a wrong-disk manual install happens); felhom background. | S | idea | Origin: 2026-07-18 rehearsal, alongside R-21's physical closure. **Squashfs/theme rebranding explicitly DEFERRED** — this item is the menu and the safety, not a skin |
+| R-40 | **[P2-HIGH] The update path cannot express a MULTI-HOP major upgrade.** A template pin is a single value; the customer's update button pulls whatever the catalog now says. For apps whose upstream forbids version skipping this produces a broken upgrade. Nextcloud is explicit: *"You cannot skip major releases. Please re-run the upgrade until you have reached the highest available release."* Campaign 7 moved its template **31 → 34** (a fresh deploy validates fine — 302, 3/3 healthy), so an existing 31 customer pressing update would attempt a jump Nextcloud refuses. | M | idea | Origin: CAMPAIGN 7 (`audits/CAMPAIGN-7-catalog-sweep-2026-07-19.md` §7 F7). Not nextcloud-only — any app with sequential-major rules (gitea, tandoor, outline…) has the same shape. Directions: a per-app `upgrade_path:`/`max_hop:` in `.felhom.yml` that the update button walks in stages; or refuse-and-explain when the installed major is >1 behind; or pin an intermediate "stepping-stone" tag. **Until this exists, a >1-major catalog bump is safe for NEW deploys and unsafe for the update button** — which is exactly the asymmetry the campaign's MAJOR flag was meant to record but cannot enforce |
+| R-41 | **[P2-HIGH] The catalog has no standing "does every template still deploy?" check.** Campaign 7 was the first thing that ever tried to deploy all 53 apps, and found **5 that had NEVER been deployable**: papra (missing required `AUTH_SECRET`), zipline (v4 renamed `CORE_DATABASE_URL` → `DATABASE_URL`), wishlist (Docker Hub image gone; upstream moved to ghcr.io), homebox (upstream dropped the `v` tag prefix + new required env), glance (needs a seeded `glance.yml` the template never provides — PROVEN pre-existing: the pre-campaign v0.7.4 pin fails identically). Plus **7 broken healthchecks** and 2 apps whose images no longer resolve at all (plant-it, wanderer). | M | idea | Origin: CAMPAIGN 7 (§7 F5/F6). The repo already has the right pattern in `scripts/check-image-pins.py` — a mechanical gate run on every change. Cheap first slice: a **resolvability gate** (`docker manifest inspect` every pin) would alone have caught plant-it, wanderer, wishlist and homebox, and needs no box. Full slice: a periodic deploy-all sweep on the demo box reusing the campaign's engine. **Silent rot is the real risk** — an app can die upstream and nobody learns until a customer clicks Telepítés |
+| R-42 | **Ruling needed: do DB/cache sidecar majors follow the app, or the newest tag?** Campaign 7 deliberately did NOT bump sidecar majors (postgres 16→18, redis 7→8, mariadb 11.6→12.3, postgis 16→17) while bumping ~40 app images to current. | S | **decision pending (Viktor)** | Origin: CAMPAIGN 7 §4. The case for not bumping: a DB major is a **data-plane decision the application owns** — immich proves it, upstream pins one specific tested `postgres:14-vectorchord…` build — and `postgres:16-alpine`/`redis:7-alpine` already track the newest patch inside their major, so they are not stale. The case for bumping: EOL majors eventually stop getting security patches, and "we never bump" silently becomes "we ship EOL databases". Suggested shape: per-app sidecar pin follows **upstream's own compose** where upstream publishes one, else stay within the current major and revisit at that major's EOL date |
