The three key files and their public halves ride the nightly encrypted DooPlex→ep0 copy (`scripts/dooplex-offsite/`, a missing key refuses the push); the Sunday restore test proves each private key still derives its own public half (never printed). **LEFT:** the operator prints S6a/S6b (`runbooks/break-glass-sheet.md`); the keys still have no passphrase (custody ruling 1 of 2026-09-16 stands until the first sale). | operator: print | Operator: print the two keys; then close | operator |
 | **R-132** | Security & access | P3 | **`curl -w '%{redirect_url}'` reconstructs the request URL WITH its basic-auth credential** — so a `-u ":$HUB_PW"` call that never put the password in a URL still printed it **Merged 2026-10-05 from R-350 (duplicate):** (1) 2026-08-20 occurrence: POST /configuration/artifacts answers 303; leak lives only in the CC transcript under ~/.claude/projects/ on DooPlex, not in git/evidence (checked then). (2) `-v` and `--libcurl` also re-render the credential, not only %{redirect_url}; confirm redirects with %{http_code} + follow-up GET. (3) Rotation path: hub /configuration form (current_password/new_password/confirm_password); DB override wins over ConfigMap (break-glass); CC can rotate file-to-file without printing (operator-present-one-time-secrets) if asked. | **WAITING-ON-OPERATOR** — **ACTION: rotate `HUB_PW`** **Folded R-580 2026-10-03** (the same `curl -w %{redirect_url}` credential echo, seen again 2026-09-18). | — | Happened on 2026-07-31 while red-proofing the R-120 gate: the hub operator password was written to the session transcript by the write-out format, not by the request. `-u` is safe; the *reporting* was not. Rule: read the redirect from `-D -` and grep `^Location:`, never `%{redirect_url}`, on any authenticated call. Rotate the hub password (`/configuration` → Login password; ConfigMap `auth.password_hash` is the reset path) and update `~/.config/credentials` | Viktor |
 | **R-137** | Security & access | P3 | **Cloudflare geo-WAF rules are zone-scoped and non-namespaced — four cross-tenant faults.** `globalRuleDesc = "[felhom-geo] Global"` (`waf.go:18`) is one literal description per ZONE; `appRuleDescPrefix` keys by app name with no customer (`waf.go:21`); `BuildGlobalExpression` has no positive hostname scoping (`waf.go:241`); `applyDiff` deletes every `[felhom-geo]` rule not in THIS box's desired set (`geosync.go:320`) | READY (M) — **blocks shared-zone onboarding** | — | With two customers in one zone: they overwrite each other's Global rule forever; one customer's country policy applies zone-wide; per-app rules collide by name; and disabling the feature for one (or the hub's `RemoveGeoRules`) wipes them all. Interim mitigation, no code: keep geo-restriction OFF for every shared-zone customer. Fix = namespace descriptions by `customer_id` + add `http.host ends_with "<domain>"` to both expressions — a TWO-REPO change (controller + hub `RemoveGeoRules`). Same audit §5.1 | CC |
 | **R-255** | Security & access | P3 | **The check that would catch a fourth secret-in-the-body covers 4 of 27 pages, and the cheap gate that covers all 36 templates is blind to the shape that actually shipped.** Filed 2026-08-08 while closing R-254, **because a partial guard reported as complete is worse than no guard — it stops the next person looking.** **Two nets, both measured.** **(1) `scripts/secret_in_markup_gate.py`** reads all 36 templates and convicts any `{{ … }}` naming a secret unless allowlisted with a reason. It catches `{{.RetrievalPassword}}` and `{{.InitialCreds.Password}}`, **and it catches a launder through a local variable** because the assignment itself names the secret (`{{$v := .InitialCreds.Password}}` is convicted — verified). **It is blind to a secret arriving under a NEUTRAL PAGE-DATA KEY** — `data["Tagline"] = creds.Password` then `{{.AppInfo.Tagline}}` passes it cleanly, also verified. **That is exactly the shape of R-254 site two** (`value="{{$val}}"` inside an `{{if eq .Type "secret"}}` branch), so the gate **would not have caught one of the three instances it was written for.** **(2) The runtime body assertion** — render the page and grep the response for a sentinel — catches every shape, including that one (demonstrated on the same planted leak the gate missed). But it needs each page's data to be constructible in a test, and **only 4 of 27 page templates have that today**: `settings_security`, `app_info`, `deploy`, `backups_restore` — the four that were touched by R-249/R-252/R-253/R-254 and therefore got their own tests. **The other 23 pages have no runtime coverage at all.** **What closing this needs, so the cost is not re-estimated:** a per-page data fixture for the remaining 23 (most need a wired `Server` — `stackMgr`, `backupMgr`, agent seams), then one table-driven test that renders each with a sentinel substituted for every string in its data and asserts the sentinel is absent. **That is real scaffolding, which is why it was NOT built inside R-254's session** rather than half-built and declared done. | **READY** — owner Viktor | — | — | operator |
