CAMPAIGN-5 findings doc (2026-07-14): NAS re-arm ring core + v0.129.0 fix live-proof

Findings-only. v0.129.0 F-A/F-B/F-C all CONFIRMED FIXED live on the fleet. NAS
re-arm ring core PASS on a fresh campaign NFS share: F10 start-limit clear +
reset-failed+rearmed, F9 per-share verdict (no empty sweep), F1/F2 clean removal,
F12 unit cycle-free. F8 improved (stub/mounted:false during outage) but reachable:true
still server-level. Reboot half of the matrix + upload/browser planes deferred with
procedures. No credential/R/blob committed.

 ### Verdict
-Data-movement + reboot-recovery planes are solid on the paths exercised; three real product findings surfaced. **The F12 reboot-safety fix (the CRITICAL that ended CAMPAIGN-3) HOLDS** — a drill-host reboot storm (5 boots) produced zero ordering cycles with full networking/WG/agent/capabilities(63/63)/guest/controller recovery every time. `.fab` export→download integrity is byte-perfect.
+The v0.129.0 fixes are **confirmed fixed live**, and the agent v0.85 NAS **re-arm plane holds** on the core matrix. No CRITICAL/HIGH regressions in the exercised scope.
 
-### This is a partial, honestly-scoped campaign
-A single unattended session cannot faithfully run the full 8h/two-box/nine-phase destructive matrix without fabricating results; priority items were executed with real evidence, the rest is deferred with reasons + ready procedures. Nothing claimed was not observed. Endurance samplers run all night.
+### v0.129.0 fixes — all confirmed fixed live (the campaign's mandate)
+- **F-B:** drill 0.129.0 — 6 direct wrong logins (no XFF, distinct ports) → limiter engages on attempt 6; proxied path also limits (pre-fix: direct never limited).
+- **F-A:** demo download estimate → `data_size_bytes:74375`, `size_unknown:false` (real container-view du; pre-fix: 0).
+- **F-C:** drill escrow `phase:none` claim → HTTP 404 with clean Hungarian message (pre-fix: 502).
 
-### Top findings
-- **F-B (MED, red-proofed):** login rate-limiter never engages on direct (non-proxied) connections — `handleLogin` keys on `RemoteAddr` (IP:PORT) when `X-Forwarded-For` is absent, so distinct ephemeral ports never accumulate the counter. Prod-mitigated (proxy always sets XFF; limit=5 confirmed with a fixed XFF); direct-to-controller paths evade brute-force protection.
-- **F-A (MED):** export size-estimate blind to docker-volume data — `download/estimate` reports `0 B`/"3.6 KB"/`fits_on_dest:true` while the real bundle is 1.2 GB; the pre-download honesty/free-space check is meaningless for volume-backed apps.
-- **F-C (LOW-MED):** `POST /api/escrow/claim` with no active ceremony returns HTTP 502 instead of a clean 4xx.
-
-### Risky steps (operator-authorized mid-run, test env) — executed
-- **Demo HOST reboot — PASS (the load-bearing one):** host down ~29 s; **0 ordering cycles even with an active nas-media nfs4 mount**; caps 63/63; WG recovered. **P6 retirement reboot-proof PASSES** — all three USB drives re-established from agent units alone despite device letters reshuffling; `/api/disks` cards persist registry-sourced (no class badge); nas-media nfs4 re-established with **0 rbind/rc255** (F13 did not manifest). Drill VM restarted + recovered clean.
-- **teszt_enroll drive cycle — PASS:** eject/reattach work; the `.fab`/format **wipe-gate + mount-guard + customer-confirm gate** all correctly refuse an unsafe format (no accidental wipe). Two LOW observations (O-1 mount_path eject doesn't fully release the device; O-2 `assign` returns 200 without sync-restoring the mount). teszt data intact.
-
-### Also passed
-`.fab` export→download byte-integrity (ref==LAN sha256, 1.24 GiB, zero corruption); F12 drill reboot storm (0 cycles, 63/63, ×5 boots); CSRF 403-JSON; escrow preflight honesty; P0 baseline both boxes; P8 samplers live.
+### NAS re-arm ring core (fresh campaign NFS share, DooPlex→demo) — evidenced PASS
+- Enrollment (add wizard, verify-before-commit): PASS. Unit F12-clean (no network-online ordering).
+- **F10 core:** `exportfs -u` → force-unmount → 6 accesses → `mount-start-limit-hit`; `systemctl restart felhom-agent` → **reset-failed on both units** + `enable --now`, `verdict=reset-failed+rearmed`; access re-mounts cleanly, **guest stayed up**. PASS.
+- **F9 no-empty-sweep:** every share emits one verdict line (campaign5 reset-failed+rearmed, nas-media skip-active). PASS.
+- **F1/F2 residue:** clean removal — 0 mounts/units/failed/dirs on host+guest (contra C3). PASS.
+- **F8:** during the real outage → `health:"stub", mounted:false, reachable:true` — more honest than C3, but `reachable:true` still server-level. Observation.
 
 ### Deferred (ready procedures in the audit doc)
-`.fab` upload/import + CF-edge legs (need a storage-bearing box), NAS regression ring, backups tiers, escrow wizard + UI DOM sweeps + hub 8-tab ring (browser available; deferred for runway).
+The reboot half of the matrix (F10 guest-reboot, F11 idle/active on reboot, re-arm reboot-survival), F7 mid-backup cut, E drift-reconcile, the `.fab` upload full-circle, the browser escrow wizard, DOM sweep, backups tiers, hub 8-tab ring — deferred for runway (browser available; no fabrication).
 
 ### Box state
-Nothing down; both hosts + guests healthy after reboots. demo host rebooted + recovered; existing apps untouched; `teszt_enroll` cycled (data intact, `/mnt/teszt_enroll` mount pending agent-reconcile restore). drill: 6 boots, healthy, scratch `c4_integrity/` + `/root/ref1.fab` (safe to delete); escrow `phase:none` (transient) — needs a fresh ceremony for a paper R. **Campaign credential active on both controllers — rotate in the morning.** Samplers still running (stop: `pkill -f c4-sampler.sh` on both PVE hosts, `pkill -f hub-sampler.sh` on 180). Evidence at `180:~/campaign4/`.
+Nothing down. Campaign5 NFS export + dir fully removed from DooPlex (no `/etc/exports` change ever made); demo apps untouched; nas-media intact. Both boxes healthy on 0.129.0. Campaign credential active — **Viktor rotates.** No R/blob produced. Samplers running (stop: `pkill -f c4-sampler.sh` on both PVE hosts, `pkill -f hub-sampler.sh` on 180). Evidence at `180:~/campaign5/`.
