- Rename course/11-break-your-engine to 13-break-your-engine and update every
link and mention; start-module explains that Module 13 has no tests to start.
- tools/diff-tracks.mjs (npm run diff:tracks): stages both references of a
module, generates a seeded random SpellGrid level and script per seed, pipes
it to the Rust and TypeScript CLIs and diffs their output; crashes on one or
both sides fail. stagePlay takes a module number.
- register_assembled: the TypeScript track compared only the text of an
existing Assembled card, so a base re-registered with a new cost (or a
different split) silently rewrote the earlier card. It now compares every
field the engine reads, as Rust does (Modules 5-10).
New test_05_assemble_never_rewrites_an_earlier_card.
- SpellGrid CLIs: coordinates and chooser numbers are 1-9 plain digits in both
tracks (Rust accepted signs, TypeScript accepted "+2", "0x2", "1e0"); Rust
quotes card names verbatim instead of with Debug escapes; Rust joins the
minion list with "; " instead of rewriting ", ". Two new CLI tests per track.
