N100 polish — F5 guest auto-sizing (host-install v1.17.0) + docs — 2026-07-17

Closes documentation/tests/VALIDATION-n100-baremetal-2026-07-16.md F5 (MEDIUM). Companion to the controller v0.141.0 F6/F7 fixes (see the felhom-controller REPORT). bash -n + the mode harness pass.

F5 — appliance guest auto-sizing (`scripts/felhom-host-install.sh` v1.17.0)

The golden default (2 GB RAM) reached the guest on a 16 GB host because appliance mode passed no --memory/--cores. Now, in appliance mode with no explicit cap, the guest is auto-sized from the host: autosize_guest_caps runs right after mode validation (before the plan summary + provision) and fills MEM_MIB/CPU_CORES:

RAM = clamp(host-4096, min 4096, max host-2048) then a hard ceiling host-1024 (never over-commit). Sizing: 8 GB→4096, 16 GB→12288, 32 GB→28672 MiB; a 4 GB host→3072 (min capped at the ceiling — the edge rule).
cores = host-1, min 2.
An explicit --memory/--cores ALWAYS wins untouched; byo mode still requires explicit caps (never auto-sized). The values flow into the existing cap_args → the agent's -memory/-cores.
Host reads (MemTotal/nproc) are overridable via FELHOM_FAKE_MEMTOTAL_MIB/FELHOM_FAKE_NPROC.
Red-proof: hostinstall-mode-harness.sh new F5 section (8/16/32 GB + small-host edge + explicit-flag precedence) — the auto-size log line is emitted before any PVE contact, so it asserts portably; pre-fix (auto-size disabled) FAILs, post-fix PASSes.

Same commit (R-16 doc-drift leftover, R-20 closure note): the operator-signing-keys "EMPTY by default" comment was stale (the keys are PINNED to the real felhom-op-1/felhom-rec-1 ceremony keypairs) — corrected, comment-only, no behavior.

NOT live this task

F5 is validated by harness only — live at the next from-scratch rehearsal (Viktor's planned delete/re-create run); stated in the ROADMAP and the VALIDATION disposition.

Docs updated

VALIDATION-n100 F5/F6/F7 dispositions → FIXED-in-vX (erratum style); capability map drive-wizard row → F6 fresh-USB wizard enroll+format PROVEN-LIVE; ROADMAP R-16 (doc-drift bit closed), R-22 & R-13 already PROVEN-LIVE, new R-24 (guest resources as hub desired-state / live resize — the F5 follow-on); operator-sidebar item #1 (BIOS "State After G3 → Power On") added to scripts/iso/README.md.

Operator sidebar (Viktor — CC does NOT do these; recorded verbatim)

BIOS "State After G3" → "Power On"/"Last State" before final sign-off — added to scripts/iso/README.md hardware-prep notes.
campaign6 autofs orphan — clears at the next host reboot.
tied-CreatedAt flash duplicates (audiobookshelf/komga/romm) — standing action item.
