about 10% of its time, JSON tree 6%, HTTP 2%, inflate 0.06%, the rest none; the cost a tree built item by item, 64 ns an item and 250 ns a copy): lend and detach (CoW) noted as the decision point (a branch on every event list's change for 10/6/2/0/0/0), a compile-time move ruled out (it changes LIST_VALUE's contract), the arrays copied whole built (UAX #14 -6.8%, its share to about 3%); 041's five works within 0.03% (b49, b50), the bank's queries within 0.3% (s49, s50), noise between builds larger

change), so a bytes state joined while empty (HTTP's pending + packet.data) no longer copies the packet: HTTP a packet at a time 288 to 270 ns a byte at the same instructions, as the old app (270.0); counts: b48 against b47 knapsack without batches -0.42%, join -0.16%, BFS with batches -0.12%, the rest within 0.03%; the bank's queries (s47 and s48 in turns, six each) in_credit -0.34%, field -0.34%, found -0.22%, per_branch -0.20%, large -0.18%, ranks -0.13%, none the same, the seven answers the same bytes

flagged PURE_TEXT_BYTES in state_flags (so serve's same_states compares it for queries and replaces), its TEXT_LOAD giving bytes and its TEXT_SET taking them, a cursor's ops on it refused (anchor in bytes) and an anchor in it refused at load; one store file text-NAME, the values record marking each bytes state (kind 7, its name, 8 zero bytes), a text state's file that is no UTF-8 its initial value when marked and store_error when not (as before); a replace carrying bytes to a text only when its draft is UTF-8, else opening the store's draft anew; pure-run shows a bytes state's hex; unit test bytes_states (seven starts from a store: 0xff and 0x00 kept, bytes to text to bytes to text with no UTF-8 and with it; three replaces; four refused); counts: b47 against b46 BFS with batches +0.12%, the rest within 0.001%; the bank's queries (s45 and s47 in turns, six each, bytes compared among them) in_credit -0.31%, per_branch -0.18%, ranks -0.11%, the rest within 0.01%, the seven answers the same bytes; Pure, Vega and aup checks green; 008, 028

TEXT_COMPARE's argument takes PURE_COMPARE_BYTES (bit 8) beside its relation, its two then bytes (UTF-8 asked of neither), as CONCAT's argument says bytes; verified as A_ORDER (a relation, and the bit), the executor relating by the argument's relation alone; the JIT, the tier and the batch executor leave TEXT_COMPARE to the executor as before; unit test bytes_compared: eight relations of a constant's bytes, none, 0xff and 'A' (0xff after 'A', a longer after its first byte), four refused (the bit on texts, no bit on bytes, a text with bytes, a relation past NE); counts: b46 against b45 the same on all five works, with and without batches; 008

takes digits (bits 20-24 as FIXED's), an integer's last N digits written after a point (1234 at two is 12.34, -5 -0.05, 0 0.00; width and zeros after the sign), verification allowing digits on FIXED and DECIMAL alone; unit test: ten rows of formats_and_held (-2^63 at two, 25 digits, a number's whole 1234, its 12.5 a limit); TPC-C's money i64 cents and its rates ten-thousandths (tables, messages, load, the transactions), SQLite's INTEGER columns and int64 bindings alike, the comparison now exact (no 1e-9 tolerance): after 20,000 transactions every row of every table the same (grouped SQLite too) and 3.3.2 holding on both; counts: b45 against b44 BFS without batches +0.09%, the rest within 0.001%; the bank's queries (s44 and s45 in turns, six each) in_credit -0.59%, per_branch -0.34%, ranks -0.20%, the rest within 0.01%, the seven answers the same bytes; 008 (NUM_TEXT's digits, a message row's i64 cells), 027 and 092

the result checked against the range (overflow past it), so a sum past the range midway and back in it at the end is the answer and an i64 sum's order is none of its business; the batch executor's folds are numbers' lanes alone, summed in the items' order, as before; 008's FOLD says so; counts: b44 against b43 within 0.04% (BFS without batches -0.03%); the bank's queries (s43 and s44 in turns, six each) per_branch -1.32% (all six below s43's lowest: a larger Fold lays the number sum's loop otherwise), in_credit -0.72%, ranks -0.26%, the rest within 0.01%, the seven queries' answers the same bytes on both; 008 and 027

default of literals and of counts, positions, lengths and u32 fields, whole to 2^53 exactly; i64 the exact integers past it, bits and money, never mixed, moved by number() and i64() when exact), / a number's division, // the floored quotient, i64 folds exact (only the result in range, so in any order), number folds in order unless the batch executor's 2^53 test says any order is exact, money as i64 minor units shown by .Nd, a replace carrying number, bool and i64 when exact; 5a: opcode FLOORDIV (95, 96 now): a number's floored quotient as Python's float //, exactly (a less its floored remainder, divided, to the nearest whole; a zero signed as a / b; by zero divide), a new opcode so the JIT, the tier and the batch executor leave it to the executor; unit test floor_division (7 // 2, -7 // 2, 7 // -2, 1 // 0.1 = 9, 0 // -3 = -0, 1e300 // 7, by zero); counts: b43 against b42 within 0.001% but BFS without batches -0.09%; the bank's queries (s42 and s43 in turns, six each) -0.20% to 0.00%; 008 and 027

nesting (nesting), a run keeping PURE_MODULE_NESTING (8) on its stack as before and a module nesting deeper running in the executor that calls, its loops in its app's room (PureApp.deep, grown to it), so run()'s hot path is as it was; the JIT compiles modules nesting 8 at most; a function's nesting counted without a cap (u32), its frame sized to it; unit test: 40 loops nested, run to their end (2^20 rounds) and stopped by the work budget (2^40), 8 still on the stack; counts: b42 against b41 with batches BFS -0.12%, without BFS +0.09%, the rest within 0.001%; the bank's queries (s41 and s42 in turns, six each) in_credit +1.04%, per_branch +0.60%, ranks +0.36%, the rest within 0.01% (their spread: the bank has no functions, so none runs the changed executor, and s42's in_credit is within s41's own earlier six); 008 and 027

header's u16s alone (16 and 128 before); a stored list's record graph (PureLayout) holds a few records itself and more on the heap, 256 at most (an image numbers them in a byte), an image or a checkpoint not written then without room for it; a record's 16 fields kept, the list engine's width (a leaf's columns, a run's columns and narrow cells, the arrays' and packs' columns), to be widened with the lists' shapes sized to their fields; unit tests: 20 records of 10 fields (200 in all), an item of the last appended; a stored list whose six records each hold a list of the next saved and read back after a restart (its graph on the heap); counts: b41 against b40 with batches BFS +0.12%, without BFS -0.09%, the rest within 0.001%; the bank's queries (s40 and s41 in turns, six each) within 0.09% (the first three's in_credit +1.16% its spread: 2.75% between runs of one build); 008 and 027
