feedback7: merge fb7-dobermann — 教鞭 is the official three-choice (PR #353 by @Sukvii, the owner's decision), the Final Assault / Hidden Core pay a 战术特训 card's perfect coins (guarded by b.progress leaksBy), the bots put zero-range heavy guards on the road first (PR #339 by @IceCodeNew, placement only)

- Conflicts (the branch started at ae22335c): spec.js / protocol.js b.progress (resolved from fb7-ui-backlog + leaksBy),
  gameLogic.js / game.js exports (device tips + normalizePersonalChoice), docs/PLAYING.md / design/network.md lines
  merged against the base, META.md (画卷 note + 教鞭), test/docs-consistency.test.js pin (both fields).
- Grok review: MERGE AFTER FIXES — the HIGH (a forged boss result paid the cards) fixed on the branch (66a228c6), the
  META wording (1ab12763).
- Golden: matches 10 (the 杜宾 bot picks and the guard placement); union: coop3-ABYSS-5 differs from HEAD only in ai_2's
  dmgDealt (1238011 → 1186269), no outcome change — HEAD's side had moved it, the new placement applies on that path.
- Broad node --test 5623 (5621 pass, 0 fail, 2 skipped); lint 0 errors; typecheck; i18n strict clean.
