Lucas WintherandClaude Opus 5.5 97c64ebee8 feat: log tree from Module 2 (logTree / log_tree); SpellGrid CLIs print Log:

Engine events carry the nesting depth they were recorded at; the harness
prints the log as an indented tree. New tests test_02_log_tree_shows_nesting
and test_03_log_tree_death_phase; both SpellGrid CLIs print the tree of the
last command's Sequences under a Log: line.

Module 7 reference engine (TypeScript)

The course's own engine as of the end of Module 7. Part I's card engine is unchanged, and all of its tests still pass. The Part II engine in src/engine/puzzle/ now reads IS NOT and resolves the parsed rules into the rules in force. Module 6's reference was the starting point, so a diff between the two shows what this module adds.

cards/ (at the package root; not in this directory): Part I's card data, a copy of course/cards/ staged by tools/verify-references.mjs. Part II doesn't read it.
src/engine/puzzle/: the Part II engine. It names no noun: the engine's own words are the operators IS, AND, NOT, the meta-noun TEXT and the property PUSH of the base rule TEXT IS PUSH.
- grid.ts: the level format, object kinds and the board. Module 7 adds Board.get.
- word.ts: the lexicon and the lexer. Module 7 adds Selects: which objects a noun names as a subject (its own things by default, every text object for TEXT, or every non-text object), read from the word list's optional "selects" field, and Lexicon.names.
- parse.ts: the parser. Module 7 adds NOT: before a complement it negates that complement (Rule.negated); before a subject it ends the run of subjects without that subject. Each rule also records its complement's role, so a conversion (X IS <noun>) can be told apart.
- resolve.ts (new): the resolution pass. Negation first (X IS NOT Y cancels every X IS Y and stays in force), then the identity lock (a surviving X IS X cancels X IS Y for nouns Y).
- level.ts: a level in play. Every change to the board parses, then resolves. hasProperty answers for one object from the rules in force.
- index.ts: the module's exports.
The rest of src/engine/: Part I, unchanged.
src/content/words.json: unchanged from Module 6.
src/harness.ts: the adapter the course tests call. Module 7 adds activeRules and hasProperty on Baba; rules() now lists negated rules too ("BABA IS NOT YOU").

Run it with the module's tests: node tools/verify-references.mjs 07 from the course repository.
