 | **R-448** | **UPDATE ARC SLICE 4 — a guarded update: verified-backup precondition, abort path, truth at the moment of action.** Shipped controller **v0.237.0** (job) + **v0.238.0** (page) + **v0.238.1** (nightly legs skip an app mid-update, found live). Proven live on demo-hp 2026-09-13, scenarios A/B/E/F/H and the restore walk. Evidence: `audits/slice4-2026-09-13/`. **Reasoning kept:** *the precondition is the existing verified backup, not a new copy* (ruling 2026-09-02) — `backup.Tier2UnitRestorePoint`, extracted from the backups page, not copied; *age a copy by its last SUCCESSFUL Tier-2 copy, never the manifest `created_at`* (measured: the manifest moves only on definition changes); *no automatic rollback — measured per-app, the route back is the restore*; *anything that writes a restore point skips an app that is held OR updating*. Open consequences: R-472, R-475, R-476. | **CLOSED 2026-09-13 — PROVEN-LIVE** | full text: `git show HEAD~1:documentation/backlog/OPEN-ITEMS.md` |
 | **R-443** | **The Update button reported success over an app it had just broken.** Closed by slice 4 (v0.237.0): 202 `accepted, not completed`; the outcome exists only as `update_phase` after health. Pinned by `TestR443_UpdateIsNeverReportedCompleteSynchronously`. Evidence: `audits/slice4-2026-09-13/`. **Reasoning kept:** *a compose exit code is never a success signal* (spike §4: HTTP 200 over a crash loop). | **CLOSED 2026-09-13** | full text: `git show HEAD~1:documentation/backlog/OPEN-ITEMS.md` |
 | **R-439** | **The restore hold was not honoured by the update path.** Closed by slice 4 (v0.237.0): `update` joined the router's hold check; live Scenario H refused start/restart/update and the boot sweep. Evidence: `audits/slice4-2026-09-13/`. **Reasoning kept:** *a hold that only one path honours is not a hold* — the audit found the drive-return gate (restart + boot recreate) and the nightly volume dump ignoring any hold; all three fixed and red-proofed. | **CLOSED 2026-09-13** | full text: `git show HEAD~1:documentation/backlog/OPEN-ITEMS.md` |
+| **R-470** | **Four controller CHANGELOG headers (v0.233.0–v0.236.0) carried no `MinAgent:` line, while the vouch and now the declared floor read it from the header.** Closed 2026-09-13 (`felhom-controller` `f946b0d`): the four headers backfilled with `**MinAgent: 0.129.0** (unchanged)` — v0.232.0's value, proven unchanged (no commit under `internal/agentapi` since 2026-09-01; highest `featureMinAgent` 0.129.0) — and `controller/scripts/minagent_header_gate.py` (fast, blocking) refuses a newest header without the line; a prose or code-span mention does not count (decoy; red-proof F). | **CLOSED 2026-09-13 — GATED** | full text: `git show 2f5d3af:documentation/backlog/OPEN-ITEMS.md` |
+| **R-472** | **The golden cadence ruling and the hub's floor rule contradicted each other: a floor above the vouched golden delivered nothing.** Operator ruling 2026-09-13, hub **v0.112.0** (`f181efd`): a floor saved with the release's declared MinAgent is served above the golden under the same agent comparison; an undeclared one is still held and both forms refuse it (`floor_needs_min_agent`). Proven live: controller 0.239.0 reached demo-hp in 14 s and demo-felhom in 15 s from the save, hub `managed floor SERVED … from declared`. Evidence: `audits/rulings-r472-r475-2026-09-13/` 02, 03. **Reasoning kept:** *the manifest leads the floor inside the golden; above it, the release's own declared MinAgent does* (publish-train rule 1); a declaration binds to its exact floor. | **CLOSED 2026-09-13 — PROVEN-LIVE** | full text: `git show 2f5d3af:documentation/backlog/OPEN-ITEMS.md` |
+| **R-475** | **The update precondition was Tier-2-only, so an app with no second-drive copy could not be updated.** Operator ruling 2026-09-13, controller **v0.239.0** (`b93c154`): the first fresh copy in the order Tier 2, Tier 1, Tier 3 (bounded, unreachable = absent + WARN); `backup_max_age` applies to the chosen tier; nothing anywhere → back up first; refused only when no copy and no backup can be taken; the hold names the tier; a Tier-2 failure in the pre-backup is a WARN. Proven live on demo-hp: nothing anywhere → backed up first (04), Tier 1 alone (05), held naming „saját meghajtó” (07), restored from „helyi” (08). Red-proof M (age only on Tier 2) fails. **Reasoning kept:** *first FRESH copy, not first copy* — a stale mirror must not force a backup while the own unit is minutes old. Follow-ups: R-477..R-480. | **CLOSED 2026-09-13 — PROVEN-LIVE** | full text: `git show 2f5d3af:documentation/backlog/OPEN-ITEMS.md` |
