- SpellGrid cards move to course/10-spellgrid/cards; start-module and verify-references stage course/cards plus module-local cards up to the module, so M5-M9 workspaces get exactly the pre-M10 card set. - cast() rejects a chosen-target spell without a target (checkCast/checkPlay); new test_10_targeted_spell_needs_target. - Rust CLI pre-validates instead of swapping the global panic hook. - Catalog: CRIER noun; DEATHRATTLE/BATTLECRY note on lexicon vs catalog role. - Lesson: design note on mid-movement reparse.
