A misplaced machine is finally undoable by mouse. The REMOVE button sits
with the tabs rather than on a page, because it's a mode, not a machine, and
it has to be reachable from any page. It stays armed between clicks —
demolition is usually plural — and clicking open ground does nothing, so a
stray click never reads as a broken tool. Toast: "UNIT RECLAIMED. THE FLOOR
REMEMBERS."
LANE-RENDER: the hover hook is the __remove ghost sentinel. The UI has no
Renderer reference and the only channel to the ghost is selectedBuild(),
which main.ts feeds to setGhost — so while remove is armed, bus._sel reads
{def: '__remove', dir: 0}. Key the demolition tint off that def id. It's safe
because sim's place handler ignores unknown defs, so main.ts's click-to-place
fires a place for __remove and nothing happens; the UI dispatches the real
remove itself. Exported as REMOVE_DEF and pinned by a test.
A magic string shared between two lanes via a NOTES file is not a design;
contract request filed for UIBus.setGhostMode.

Round 2 per lanes/LANE-SIM.md.
- splitters: round-robin across outward-facing belts, blocked outputs
skipped not waited on; rank now traces THROUGH splitters and takes the
best outcome reachable across every terminal a lane reaches
- buffer tanks: charge on surplus, discharge to cover deficit, brownout
only once dry; bandwidth.stored is the pool
- heat v1: heatPerTick while active + RecipeDef.heat per craft, ambient
cooling, linear throttle 1.0@0.7 -> 0.5@1.0, scram at 1.0, restart
under 0.5, both edges emit 'scram'. Throttle applies to powerGen too,
so a hot decoder sags before it drops off the bus
- commission queue: data-order activation, repeat re-enters at the back
- jammed:'starved' (edge-triggered) and BeltItem.id (stable through belt
transfers and splitters alike)
15 new fixture tests for the M2 mechanics -- data/ carries none of the v2
fields yet, so heat and tanks are tested against a fixture this lane owns.

Replaces the stub with the real sim per lanes/LANE-SIM.md round 1.
- grid + placement/remove/rotate/setRecipe, footprint rotation, bounds
- belts: 2 items/tile, 0.45 spacing enforced across the tile seam,
back-pressure, merges, belt<->machine handoff
- crafting: recipe buffers (2x in, stall at 4x out), edge-triggered jams
- bandwidth v1: gen vs draw, compression generates, brownout = gen/draw
scaling both craft progress and belt movement
- shipping + commission tracking
- output routing ranks belts by tracing the chain to its terminal machine,
so the demuxer's three outputs reach three different consumers without
splitters (see NOTES - biggest judgement call of the round)
18 tests. Measured 3,500 entities + 6,820 belt items at 0.42ms/tick (80x
realtime). Full M1 chain ships MELT at tick 1149 in both node and browser.
