feat(erp-seat): run 7 quantized to NVFP4A16 and serving as the trial seat on ana-ml2

- services/erp-seat-quant/run_quant_erp_v7.sh: v6 runner retargeted; dry-run gate
  passed identically (11,725 targets, 11,520 experts = 30x128x3, routers+vision BF16)
- 49 GiB bf16 relayed gx10 -> ana-ml2 (no key path either way; nh3-dev relays),
  checksums verified against source; quant 49 -> 16 GiB, all post-steps clean
- stacks/erp-seat: .env-driven swap to erp-tune-v7-nvfp4a16, served under its TRUE
  name; homepage labels + README updated, v6 rollback path recorded
- stacks/litellm: trial -> erp-tune-v7-nvfp4a16 (config-file alias; /model/update
  refuses a config model, so this is an edit + restart)

 ## Recent decisions
 
+- `[2026-09-09]` **run 7 quantized NVFP4A16 and serving as `trial`** — 49 GiB bf16 relayed gx10→ana-ml2 (16 min, 53 MB/s), quant 49→16 GiB via `services/erp-seat-quant/run_quant_erp_v7.sh` (dry-run gate passed: 11,725 targets / 11,520 experts, routers+vision BF16), seat on `:8021` under its TRUE name `erp-tune-v7-nvfp4a16`, LiteLLM `trial` repointed (config-file alias — `/model/update` REFUSES a config model, must edit `stacks/litellm/conf/config.yaml` + restart). Rollback: v6 artifact on disk + `/tmp/erp-seat-env.v6.bak`. ⚠ **`no direct path` was WRONG** — gx10↔ana-ml2 ROUTING is fine both ways; neither box holds a private key (only `authorized_keys`), so neither can *initiate*. `ssh -A` agent forwarding from nh3-dev gives a genuine direct path, verified. The relay costs nothing here anyway: both gx10 and nh3-dev are at NH3, so the WAN hop happens once either way.
+- `[2026-09-09]` **Booth: partial ask answers are legal** (v0.1.15) — operator: the form failed when a question was left blank. `required` dropped from the radios; answered questions recorded, blanks land in `unanswered`, `complete` says whether the set is finished; refused only when there is no pick anywhere AND no notes. Reading sessions must check `complete`.
 - `[2026-09-09]` **ERP run 7 COMPLETE and the base arm is serving.** 542/542 steps in 14h17m on pfi-gx10, adapter 13:23 PT, `train_loss` 3.205 / low 2.799, merge verified a sampled target actually changed (the silent-no-op check). `erp-seat-base-ara` up on `10.100.50.60:8098` for brokkr's floors, `erp-tune-v7` merged and staged pending his cue; Miranda notified for the operator. Runbook `docs/runbooks/gx10-run-07.md`.
 - `[2026-09-09]` **Booth asks render INLINE in a custom report, placed by the author** (v0.1.14) — operator ruling: *"the asks should be inline with the artifacts, not on a separate page."* Placeholders `data-booth-ask="<stem>"` / `"<stem>:<key>"` / `data-booth-ask-submit`, plus `<!-- booth:ask … -->`; per-question fragments bind to ONE form via the HTML5 `form=` attribute so a four-voice audition submits every pick in a single POST. ⚠ The placeholder must sit OUTSIDE any grid/flex parent or it becomes a cell (measured on `redo-anchors`: a 224 px sixth grid cell). Unplaced questions + a missing submit block are appended, so a partially marked-up page can never yield an unsubmittable 400 — a test caught that as a real drop. `redo-anchors/index.html` was hand-marked-up on the LIVE copy; tts-dev told to move it into the generator or a regeneration loses it.
 - `[2026-09-09]` **The Booth gained an ASKS primitive** (v0.1.12): a session drops `<stem>.ask.json` in a booth, the operator answers a radio form + notes in the browser, the pick lands as `<stem>.answer.json` the session reads (`booth ask|asks|answer --wait`). Multi-question form via a `questions` list. ⚠ Two defects found and fixed the same day: a booth serving its OWN `index.html` never rendered the panel (verbatim path returns early) → amber chip + standalone `/b/<name>/asks` page; and single-ask `title` was silently dropped. The `booth` CLI was ALSO not on PATH anywhere despite the global link-board convention telling every session to run it → symlinked to `~/.local/bin`. Global `CLAUDE.md` now teaches the primitive.
