Self-review of the wildcard authoring spec caught two real issues:
1. Count contradiction: the new Wildcard section said '+12 free' while the pack's
authoritative counts (QUESTION_SCHEMA.md daily table + metadata, and the guide's
Required Counts + Final Production Gate 'count validation') still said 500/75. A
content agent running count validation would fail, or worse delete weekday
questions to hit 500. Reconciled all four locations to the weekday pack (frozen
500) + wildcard add-on -> 511 total / 86 free / 425 premium, and folded the
wildcard set into the Final Production Gate review sampling.
2. Rotation math: the picker indexes epochDay % poolSize and wildcard days fall ~10
apart, so a pool size sharing a factor with 10 (12 is even) only surfaces a
fraction of the questions per year. Pool size must be coprime with 10 -> 11, not
12. Documented as a hard constraint so it isn't 'rounded to 10' later.
Also hardened the section: net-new (not a patch), answer_config option mirror,
unique snake_case option ids, and a QUESTION_SCHEMA.md cross-reference.
