(constants between), checks only the last is finite, giving up at the run's first snapshot (the executor makes the run again and fails where it does); a snapshot's constants written as the constants they are, not kept in registers; the generic code's append in a loop keeping its books puts into a HASHED list as append does (its headroom kept). roots 12.2 to 10.9 ms (1.59x C), join 84 to 74 (2.5x)
module_assumptions: a run of products and sums past the largest number (CHAIN_SOURCE)

slots, as C's table: in the L3), the generic code's APPEND into a HASHED list at its key's slot while its table need not grow, a whole number over a whole one above 0 never -0 (so MINSTD's floor(x * 48271 / p) is whole and x an integer in the tier). join 108 to 84 ms (2.8x C), sort 58 to 37 (1.4x)

keyed by a text is HASHED from its first item, its table's slots holding the texts' hashes (FNV-1a), a match the key cell's bytes too; HAS and a field by key read the table; its order made by a merge sort (the first eight bytes as a number, then all). A FIND whose index only an ITEM_SET of its list takes, the code between in a line finding by key alone, sets the item where it was found (PLAN_ROW: a HASHED list's slot, no position made). words 453 to 217 ms (5.8x C)
text_keys_equivalence: adds, has, fields by key, sets where found, positions, runs, removes and clears against a tree keyed by the text

each item's cells at its key's slot in its members' table, found by key there (the key and its cells read at one slot, as C's table); its order made by a radix sort of the slots' keys when something asks for a position (twice an event, then FLAT or a tree). The tier finds by key alone in a HASHED list (its bits' bit 1, its limit all ones: the bounds checked at a loop's opening still hold) out of the line; a list keyed by each count in order is DENSE from its first item. join 531 to 108 ms (3.5x C), sort 98 to 58 (2.1x)
arrays_equivalence counts the HASHED form against a tree; module_tier's programs read a HASHED list by key

not past it; representation first, since a keyed list given keys in order stays FLAT and is searched by halves (knapsack's and matmul's 300x)

place fault where they are; now is the host's per-event value); value numbering of pure operations, which words' floor assumes

types and ranges, hoists the meaning's checks out of loops, counts work per loop, allocates registers; criteria on research 124's suite of seven kinds of work against C (each within 1.25x, the geometric mean below 1.0, the meaning's checks within 5%), from floors at 0.90x C
