Observations (noticed, not acted on) -Per §10 of the task: no catalog-wide invariant check (stays R-41), no changes to nightly cadence, -retention, quota math or tier-2, and no touching v0.147.x progress semantics beyond the one added -phase line. The missing-only button's own zero-file flash is untouched — that belongs to the v0.147 -feedback arc, not R-43/R-44. Its label now states what it does *not* do, which is in scope. - -## Live acceptance — NOT YET DONE (§9, needs Viktor) - -The genuine red-proof is the joint run over the tunnel and has not happened: upload → „Távoli mentés -most" → empty the trash for real → „Teljes visszaállítás (fájlok + adatbázis)" → photos visible in -the immich timeline. Until that evidence exists: - -- the capability-map offsite row stays **PARTIAL / scope-contested** (no PROVEN-LIVE flip), -- the customer-restore row stays **MISSING**, -- R-3 stays **DRAFT**. - -**Floor raise to v0.148.0 is Viktor's click and must come BEFORE the acceptance run.** - -## Open question for Viktor - -The capability-map row at `00-capability-map.md:61` claims PROVEN-LIVE citing `CAMPAIGN-6D`'s -"immich end-to-end from offsite alone". This diagnosis contradicts that phrase. I flagged it -scope-contested rather than downgrading a proven row — the ruling (did 6D exercise the DB half, or -only the file half?) is still outstanding and is not something this implementation can settle. +1. **An orphaned `dhclient` runs on the host for a non-existent `eth0`** (`pgrep -a dhclient` → + `/sbin/dhclient … eth0`, pid 1922) while no `eth0` exists in `ip addr`. Harmless today, but it is + leftover state of exactly the kind that makes a future network change confusing to diagnose. +2. **Accented grep patterns are unreliable through the `ssh → pct exec → bash -c` chain.** A search + for „nem elérhető" returned a false `0` while the string was present — which reads exactly like + "the banner cleared". The page content is fine; the *pattern* gets mangled in transit. Use + ASCII-only substrings for any grep that gates a conclusion. This nearly produced a wrong + "banner gone" claim before an ASCII re-check caught it. +3. **The controller password contains `'` and `!`.** A helper script written via an unquoted heredoc + had its `!!` mangled by history expansion and produced one failed login (visible in the controller + log as `[WARN] [web] Failed login`). The proven-safe form is the inline `-d "password=$PW"` the + audit run used. +4. The guest journal is **volatile** (current boot only) and the controller's logs are lost on + container recreate — which is why F5's root cause could not be established after the fact. Worth + knowing before any post-mortem that depends on in-guest history.
