GameInvariants checks card counts, unique instance ids and damage. The CLI stress command runs random legal bot games and fails on the first violation. It exposed a real bug: an optional OnGuard ability that could not be paid (or was declined) reset the step from Guard to None while the battle was still open. OfferAbility now reports Skipped/Paused/Resolved and callers continue only when needed. 1000/1000 games finish with no errors.
Pure rules library with no Orleans or database. Command in, events out. Deterministic RNG stored in GameState. Covers setup with starting vanguard and mulligan, six phases, ride, call, attack, guard, drive check, damage check with triggers, retirement and win at six damage. 8 engine tests, 30 total. Sentinel, boost and card abilities are the next step.
66 effect texts translated with icon tokens preserved. Added docs/translation-rules.md with terminology, syntax patterns and open terminology questions. Normalized the source typo Own(VC/RC) to [AUTO](VC/RC).
Dropped nameRu from the translation workflow and from content validation warnings. Progress now counts cards whose text is filled; vanilla cards without text count as done.
Solution on .NET 10 LTS with rules, content and CLI projects. Content importer pulls stats from the official card list, merges trigger/rarity data, emits three YAML sets (94 cards, 124 printings). Validator checks the grade-0 shield invariant, sentinel shield, parallel printing links, and deck construction limits. 14 tests cover catalog integrity and deck validation.
