Passing This code compiles and runs correctly.
Code
// PINS: `[id]` — a sweep can name the HANDLE of the row it is visiting.
//
// `[ordinal]` is WHERE the visit is. `[id]` is WHICH ROW it is standing on.
// Both are needed and neither substitutes for the other, which is why they are
// two annotations rather than one:
//
// - a cell that names a row names it by HANDLE, never by position (ruled).
// A take swap-removes the last row into the freed slot, so an ordinal
// written to a column outlives its meaning by exactly one removal;
// - so a body that wants to STORE a reference to itself needs the handle,
// and until now the only place a handle was minted was `| row` at insert.
// A sweep could address its row (`store[e]`) but could not name it.
//
// Both requests are synthesized ONLY when asked for — the demand-driven rule
// `[ordinal]` already carried.
//
// The consumer's spelling, and the reason this was built: an INTRUSIVE CHAIN.
// Each visited row reads the current head, writes it to its own `next`, then
// writes ITSELF as the new head — a bucket rebuild, the classic no-allocation
// spatial hash, needing no nested collection, no positional addressing and no
// verb beyond this annotation. Rows are visited 10, 20, 30, so the chain comes
// out 30 -> 20 -> 10, walked back through the handle reads 690_245 pins.
//
// `ordsum` rides alongside to pin that the two requests stay DISTINCT: the
// ordinals are 0, 1, 2 and sum to 3, while the same rows' ids are branded
// handles that address rows correctly. One value could not do both jobs.
//
// Found by the ECS benchmark's spatial grid (tests/benchmarks/003_ecs_reactive),
// which is the workload the vocabulary was waiting for before growing.
