- tools/mutation-check.mjs with tools/mutants.json: thirteen mutants against the
Module 12 TypeScript reference (the eight of Module 13's first table, plus
Armor before redirect, conditions at parse time, no defender priority, and the
summon seam's noun check); all killed.
- tools/run-scenario.mjs with tools/scenario/run.ts: a designer's cards, words
and seam words as data, played on the Module 10 TypeScript reference.
- course/10-spellgrid/designer-capstone.md and designer-example/ (output.txt
is checked against the tool's output in the tools tests).
- CI: diff-tracks (300 seeds), mutation-check, verify-levels.
- Module 13: the mutation table is the tool's output; differential testing,
undo and the solver sections describe the repository as it is. Lesson 10
says what the level proofs prove for levels 6, 8 and 9.
- schema.mjs: a value that matches no oneOf branch is reported against the
branch its const fields pick.

The solver's position key reads stackAt (each tile oldest first). New tool
tools/verify-levels.mjs checks course/10-spellgrid/levels/proofs.json: each
level's shortest solution, and that it exhausts without its idea (neverRule)
or on the naive engine. Levels 4-10, one course idea each, with
test_10_level_N_solution in both tracks, scenarios and Lesson 10's list;
l1 no longer matches l10, and proofs.json is not listed as a level.

- 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.

- lessons 8 and 9 updated for the once-per-move rule, per-object negated
conversion and the new ordering tests
- tools/solve-spellgrid.mjs: breadth-first search over a SpellGrid level
with the TypeScript reference; --never-rule and --naive
- README, harness.md and the mentor skill know the new beat and module

Lesson 10 and both M10 reference READMEs now give the real recipe
(node tools/play-spellgrid.mjs <rust|ts> [l1|l2|l3]); root script play:spellgrid.

- cardDirs: course/cards only from Module 5 (spec 6.2a); fixture modules 04/05 and tests
- coupling-audit: noun words match as UPPERCASE, PascalCase or a whole string literal;
lowercase identifiers like key/flag pass; card names keep every variant
- isMain() argv guard replaces import.meta.main in coupling-audit and verify-references;
engines.node >=22
- expansion-check: git diff --no-renames so moving engine code into content fails
- start-module and other tools: clear error when .course.json is missing
- check-links: malformed URLs reported as invalid URL instead of throwing

Re-verify Teikari article quotes and GDC speaker, soften unsourced
claims (lessons 01, 06, 07, 10), add course-simplification bullets to
lesson 07's differs box, qualify OPEN obstruction wording in research,
and add tools/check-links.mjs (report-only) with npm run check:links.
