Bug 1 (modules 08-10): a YOU object pulled by an earlier mover took a second step of its own. Level movement now keeps the ids that stepped in a committed plan this phase; such a YOU object starts no move, and Planner try_move answers no for it. Regression: test_08x_pulled_you_moves_once (Module 8 Expansion Drop). Bug 2 (modules 09-10): convert honoured negation only per rule, so ALL IS ROCK beat BABA IS NOT ROCK. A target Y is now skipped for an object if any active negated rule IS NOT Y names it. Module 9 and 10 references (and their drop solutions) now carry ALL, the Module 7 Expansion Drop. Regression: test_09_negated_conversion_beats_group. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>

# Module 9 reference engine (Rust)
|
|
|
|
The course's own engine as of the end of Module 9. Part I's card engine is unchanged, and all of its tests still pass. The Part II engine in `src/engine/puzzle/` now plays a whole turn: movement, parse, conversion, parse, hazards, win, parse. Module 8's reference was the starting point, so a diff between the two shows what this module adds.
|
|
|
|
- `cards/` (at the crate 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`, the property `PUSH` of the base rule `TEXT IS PUSH`, the property `YOU`, which picks the objects that move, and from Module 9 the properties `WIN` (the win check) and `FLOAT` (which objects share a tile).
|
|
- `turn.rs` (new): the turn. `Phase`, `TURN` (the phases in order) and `Hazard` (content's rule for what destroys what).
|
|
- `level.rs`: a level in play. Module 9 adds `Level::step`, which runs the phases of `TURN`; the conversion phase (`X IS Y` in place, `X IS X` locks, `X IS NOT X` deletes, and `... IS NOT Y` keeps every object it names from becoming a `Y`, as `has_property` settles negation per object); the hazards phase, which runs content's hazards in order; the win check; `Level::sharing` (the other objects on a tile at the same float level); `won` and `lost`. `Level::new` takes the hazards. `move_you` is now movement, then a reparse.
|
|
- `grid.rs`: Module 9 adds `Board::set_kind`.
|
|
- `word.rs`: Module 9 adds `Lexicon::thing_named` (what a conversion into a noun makes).
|
|
- `movement.rs`, `parse.rs`, `resolve.rs`: unchanged.
|
|
- `mod.rs`: the module's exports.
|
|
- The rest of `src/engine/`: Part I, unchanged.
|
|
- `src/content/hazards.rs` (new) and `src/content/mod.rs`: the hazards, in the order the engine runs them: `SINK`, `HOT`/`MELT`, `DEFEAT`. What destroys what at the end of a turn is content, not engine.
|
|
- `src/content/movement.rs`: unchanged.
|
|
- `src/content/words.json`: Module 9 adds `HOT`, `MELT`, `SINK`, `DEFEAT` and `FLOAT`, and `ALL`, the Module 7 Expansion Drop, which the Module 9 tests need.
|
|
- `src/harness.rs`: the adapter the course tests call. Module 9 adds `Baba::step`, `Baba::won` and `Baba::lost`.
|
|
|
|
Run it with the module's tests: `node tools/verify-references.mjs 09` from the course repository.
