Baba.undo() restores the level before the last step or move (board snapshot:
objects in age order with ids, the id counter, and won; rules recompiled).
place clears the history. SpellGrid's undo throws/panics 'not supported'.
stackAt / stack_at lists a tile's kinds oldest first, on Baba and SpellGrid.

A trigger is never queued while that same (minion, trigger) is resolving;
more than DEATH_PHASE_LIMIT = 64 Death Phases is an error ('Death Phase
limit'); Assemble refuses and never offers ill-formed text (wellFormed /
well_formed); summon count > 1 places tokens in summon order. Modules 05-10,
both tracks. Four new Module 5 tests, a tools test that every shipped card
is well-formed, lessons 2, 3, 5, 13 and harness.md updated.

Applying a Damage to one target now runs DAMAGE_STEPS = [redirect, armor]
first. A damageRedirect aura (Bolf Ramshield, fetched from the wiki) sends
damage meant for its owner's hero to the oldest such minion; Armor absorbs
damage to a hero before Health, logged as the new ArmorLost{player, amount}
just before a full-amount Damaged. Four new Module 4 tests; propagated to the
references of Modules 4-10 in both tracks; card schema, catalog, card JSON,
harness.md, Lessons 2, 4 and 5 updated.

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.

Mutation runs on the references showed six surviving mutants: a live aura
scan, two turn-phase reorderings, a dropped final parse, and two hazard
reorderings. Each now fails a named test.

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.

A Deathrattle summon used the dying minion's board index from before the
Death Creation Step removed anything. That index is stale when a minion to
its left dies in the same step, so the token landed one place too far right.
Each Death Event now records `before`: the nearest minion to the right that
is not dying in the same step. The position handed to the effect context is
resolved when the trigger resolves: the current index of `before`, or the
right end. Applied to the Rust and TS references of Modules 3-10.
Module 3 gains two tests, documented in scenarios.md:
test_03_summon_position_after_simultaneous_deaths (fails before the fix) and
test_03_simultaneous_summons_keep_board_order.

- verify-references --expansion overlays expansion/solution on each reference and runs the
cumulative tests plus the drop test; refuses a solution that touches src/engine/
- CI job verify-expansions
- README: workspace-template + git init step, tool list, repo disclaimer link
- Cargo.lock for every Rust reference (staged with the reference, pins serde for rustc 1.85.1)

Movement planned in full, then committed: a Planner builds a plan
(moving and destroyed ids) by running content's movement responses
(OPEN/SHUT, PUSH, STOP) for every step, rolling back failed branches.
Edge of level blocks; YOU objects move furthest-ahead first; rules are
reparsed once after movement. Harness: move/move_dir(Dir), posOf,
kindsAt. Expansion Drop: PULL as one word plus one content response.
