feedback1 WB: R11 bounty list drawn from the 7 seen lists; R9 group sizes stated as they are; official 机密商店 composition only at R11

- R11 悬赏决策: the list is one of the 7 seen lists, uniform (slots 7, taken as the events
  bounty_hunter_1..7, one block of effectChoiceInfoDict). No list is built from nothing any more;
  the rule only completes the 4 lists seen with 6 cards, so 12_8 / 16_2 / 16_6 come in about
  1 R11 bounty draft in 15 (14 drafts without one: about 39 %).
- R9: the groups hold 9, 9, 9, 9, 8 and 6 cards (comments, docs, test); match 4's base-only
  group may be a draft of another group (open). 58 -> 59 bounty drafts in the build-data note.
- 机密商店: shopDraft.rounds [11]. The official composition (VI, VI, V, 盟约之币 + 2) applies at
  R11 (绝境 / 终极, where the screenshots are); the earlier 标准 / 险境 shops keep the previous draw,
  any tier I-VI per card with replacement (repeats still possible, about 26 %).
- Tests: R11 slots / block order / never-shown rate, R9 group sizes, the non-R11 shop draw.
