docs(roadmap): R-29 — design-v2 gates unenforced; docker_run_volume_path_gate red for 16 releases

Origin: R-7b close-out (felhom-controller REPORT section 4f). Two parts:
(a) the finding is benign — estimate.go:179 mounts a NAMED VOLUME (daemon-side, no
    host path), the same shape as three already-allowlisted entries, so the fix is a
    3-line ALLOWLIST addition with its WHY, NOT a docker-cp rewrite;
(b) the systemic half: the gates run only when a human remembers, so this one sat
    red from v0.129.0 (2026-07-14) to v0.145.0 while REPORTs said green. Second
    instance of the class after the v0.123.0 'Windows green gate silently red' note.
Lists the full gate inventory to audit for the same rot.

Pipeline must ship a firmware-compatible loader / PXE path. Reused-customer edges (F2 claim re-issue, F3 offsite re-issue, F4 non-default-storage-id ACL 403) feed R-1/Peti. UX: F6 drive-init doesn't mount+attach, F5 guest-RAM not configurable, F7 back-route. — **Slice A (build pipeline + first-boot bootstrap) DONE + validated on VM 310:** build gate/red-proof, disk-filter fail-safe, stub→retry-unit→real public-channel host-install fetch+invoke→retry, resume-decision, exactly-once, no-net retry+recovery all GREEN. Operator-gated remainder: host-install rc-0 terminal success (drill customer needs the password-gated create-UI). **Slice B — SHIPPED (scripts v1.18.0, 2026-07-17):** the F1 firmware fix is now a first-class pipeline mode `build-felhom-iso.sh --loader shim|mkimage` (default shim; `mkimage` = monolithic grub-mkimage loader from the ISO's own GRUB, recipe from the run evidence). RUNBOOK-B legs on nested VM 311 proved it: shim boots+installs under OVMF SB-enforcing + SeaBIOS; mkimage boots+installs under OVMF SB-off; mkimage under SB-enforcing FAILS `Access Denied` (unsigned → **SB must be OFF**, documented); surgery byte-identical payload. **Physical N100 boot on the real board still pending** → folds into the supervised rehearsal (R-1; an `n100-safety` match-nothing ISO is built + sha-recorded for a zero-risk pre-flight). **PXE/network-boot** (the third F1 option, for boards where even USB-mkimage fails) stays a deferred note under this item — not built. **Slice C — SHIPPED (hub v0.62.0 + scripts v1.19.0, 2026-07-17):** the GENERIC secret-free universal ISO (`build-felhom-iso.sh --pairing`). The box self-registers as an unclaimed appliance (keyed by SMBIOS-uuid + MAC set — the DMI-verdict tiebreaker), the operator BINDS it to a customer on the Hosts page, and the hub delivers customer-id + retrieval passphrase ONCE (`/api/v1/appliance/register` + one-shot poll, 404-no-oracle — all live-verified through the public ingress); the bootstrap then falls through to the slice-A direct path. **One unit, two modes** (direct = byte-identical, regression-proven zero-appliance-calls). Artifact proven secret-free (baked env = hub URL only; manifest `secret-bearing: no`). The **bind is operator-password-gated** → the live boot→register→bind→day-0 composition (with a Viktor-created drill customer) + the physical N100 boot fold into the supervised rehearsal — **which now runs the COMPLETE final product flow in one pass: RESET the demo → boot the generic ISO → bind → day-0**. SSH-host-key pinning: stored + fingerprints displayed (attaching to the host on bind = future, no clean hand-off surface today). **Customer-facing self-bind page = R-27 (future).** Origin spike `audits/SPIKE-baremetal-iso-2026-07-16.md`: every mechanism GREEN on nested virt (VM 310 on felhom-pve). Zero-touch install BIOS **and** UEFI incl. **Secure Boot enforcing** (no MOK/keypress); first-boot hook `fully-up` = root + working pvesh/pct, exactly-once via `pending-first-boot-setup` flag; post-install **webhook** carries SMBIOS-UUID + management-MAC + host SSH keys → the unclaimed-appliance record; disk-filter installs only the target (canary byte-identical) and **fails-safe** on match-nothing / bad disk; `from-url` + `cert-fingerprint` **fails CLOSED**. OPEN (needs ONE real bare-metal run): vendor DMI serials (empty on virt), real firmware/NIC quirks, a pre-existing-LVM wipe step. Pipeline notes: assistant pairs to the ISO by Debian codename, ~11.5 s/ISO on DooPlex, **gate on `validate-answer` output not `$?`** (exit 0 on failure). Would flip a new capability-map MISSING row "customer self-installs on bare hardware" once spec'd. *(brief called this R-22)* |
+| R-29 | **The design-v2 green gates are not enforced anywhere — one has been RED for 16 releases.** `controller/scripts/docker_run_volume_path_gate.py` has failed continuously since **2026-07-14 (v0.129.0)** and nobody noticed until R-7b's close-out ran it by hand at v0.145.0. Two separable parts. **(a) The finding itself is benign and the fix is 3 lines.** The flagged call is `internal/appexport/estimate.go:179` `docker run --rm -v <volumeName>:/vol:ro alpine du` — a **NAMED-VOLUME** mount, i.e. daemon-side with no host path, which is the *safe* shape and byte-for-byte the same pattern as three entries already on the gate's ALLOWLIST (`export.go` `volName+":/vol"`, `backup.go` `volName+":/vol:ro"`, `restore.go` `volName+":/vol"`). It is NOT the v0.124.0 path-strand class the gate exists to catch — the author of the v0.129.0 F-A fix explicitly avoided that class (see the function's own comment) and simply never added the allowlist entry. So the fix is an ALLOWLIST addition WITH ITS WHY, **not** a docker-cp rewrite; anyone who 'fixes' this by rewriting the call has misread the gate. **(b) The systemic half is the real item:** the gates run only when a human remembers to run them, so a gate can sit red across 16 releases while every REPORT says 'green'. This is the SECOND instance of the class — cf. the v0.123.0 note *'Windows green gate silently red (read-only fsync)'*. Decide where they run (pre-push hook, `build.sh` step, or a CI job) and make a red gate block the train the way the Go green gate does. | S (a) / M (b) | idea | Origin: R-7b close-out, `felhom-controller` REPORT §4(f) — CC correctly left it alone as out-of-scope and pre-existing, and verified by stashing that it fails identically on the unmodified tree. Flips no capability-map row (engineering hygiene, no customer-visible behaviour). Affected gates to audit for the same rot: controller `template_id_gate` / `emoji_gate` / `native_confirm_gate` / `offbox_rename_gate` / `mojibake_gate` / `app_row_dedup_gate` / `docker_run_volume_path_gate`, hub `hub_confirm_gate`, manifests `manifest_bearer_gate`, website `site_gates`. **Do not bundle (a) into an unrelated feature commit** — it is a one-line behavioural claim about a mount's safety and deserves its own reviewed diff |
