holding bytes doing their work: no collections table, DOC, DOC_SIZE or REPLACE (106 opcodes now 103, those from LEN on moved up), keyed messages or a base revision (pure_app_message takes an input and a payload), no PureData document callbacks (a data host opens states and saves them together), no burst by document key; the header 38 bytes; pure-edit-module gone; pure-serve without /objects, ETag, If-Match and If-None-Match, 412 or an app a thread for a module of documents alone (one without states or outputs runs so); a hole closed: an instruction in no handler's, view's or function's block was never verified yet the load's later passes read its arguments (a damaged module read out of bounds once the header moved what the mutation test damaged), now blanked to CONST 0; checks moved: server_documents (DOCS_SOURCE, keyed byte documents with the app's revision, against a Python model, one and three connection threads, a restart) in place of the parity with editor.pure, pipelining and bursts through kill -9 on its inputs and views, the lent budget on a text view (lending a document's read is server_lent_views' already), clocks and tokens on it; message tests without a document host; the HTTP benchmark's document suite runs the earlier document server and the baselines alone; the count harness builds against either message API (runs.sh build: -DPURE_KEYED_MESSAGES before 4b); counts: b33 against b32 with batches within 0.002% but BFS -0.33%, without batches BFS +0.63%, knapsack +0.52%, join +0.38%; the bank's queries (s32 on a v6 module, s33 on v7) field +0.68%, found +0.44%, large +0.42%, the rest within 0.13%; 008 as v7, 027's 4b-2 as made and 4c designed

5): held as a text is but for UTF-8, its default a constant; a function's bytes in a signature this type too (PURE_SIGNATURE_BYTES gone); no list keyed by bytes; replaced, a text field becomes a bytes field keeping its value (pure_cell_as, kinds_carry); images' headers take its kind; the JSON edge reads it from a string; pure-run shows it as hex; an append asks a record's fields held as bytes from a mask the load makes (record_held) instead of each field's type twice, so b32 runs fewer instructions than b30 (BFS without batches -1.05%, join -0.25%, BFS with batches -0.36%, the rest within 0.04%; the bank's queries s30 against s32 -0.01% to +0.30%); unit test bytes_fields (bytes not UTF-8, a text field replaced by a bytes field, three refused); server_trees with a bytes field; 008 and 027

rows whose records hold lists are read, as the message arrives, by stage 3's decoder into the event's lists (value_take into the rows' list), the event beginning with them; the JSON edge reads an object's array as its record's objects, 64 lists deep at most (items_of: an item's lists encoded first and the item moved down over them); the load no longer refuses them; a hole closed: the decoder read past the end where fewer than 4 bytes were left for a length (size - at - 4 wrapped around), unseen while it read only what was stored; unit test nested_rows (three events, four rows not whole changing nothing); check server_trees (300 random forests over HTTP against a Python model walking them in the same order, a require refusing some, a list field not an array, a field the record lacks and 65 lists deep refused, a restart); counts: b30 against b29 within 0.001% but BFS with batches +0.12%, the bank's queries -0.00% to +0.23%; 027's stage 4 planned in six steps (4a to 4f, the counts it starts from, 4b in two commits) and 4a as made; 008 on nested rows

(aup's stored_nested) alike in memory and on a store restarting eight times, every step's fault, states and a view (2,400 snapshots, 54 restarts); killed at the tree's four stages and the log's two, all or nothing; replacement moving nested lists by name at depth; appending into a stored item's list costs about 170 ns an item it already holds (append_cost.c: 42 µs an add on average over the first 500, 738 µs over 8,000), building one by appends quadratic; instruction counts: the first commit's BFS +1.45% with batches and +1.68% without, from branches in the hot steps, gone with the load's internal ops (b29 against b27: BFS 0.000%/+0.034%, the others within 0.008%; the bank's queries -0.25% to +0.22%); what remains (a message's rows holding lists, a list field's .count in a fold, for over xs[i].f); 027's stage 3 as made (the representation chosen against the plan, its cost); 008's wording (kind 5 in images' headers alone); CHECKPOINT's direction row through stage 3

descent (aup's examples/json_tree.aup: value(d, i) -> Json, number giving the value and where it ends, each call's own let's lists, string's escapes joined by char(u), a depth-first walk passing items as values) against Python's reading walked so: JSONTestSuite's 95 y_ taken alike, no n_ taken, 2b's 6 i_ taken (a lone surrogate refused by char as encoding); 100,000 and 50,000 deep refused as memory (the frames fill the event's room, 0.2 s), 30,000 deep taken (past Python's json); 300 random documents alike; in make check (module_specs' digest now depth first, three paths); 142 lines against the same design's 105 in Python (json_rec.py; the bar missed: 24 lines of declarations, 23 of braces), 46 times cJSON's time and 1.6 times plain Python's (600 ns a byte, 248 Pure instructions; 71% in the steps, about 10% in calls, 66,000 calls a document, most of them small block fns like skip); characters against Python's ord in aup's check; probes: p5-chars compiles, p4-rec (a view calling itself) refused; instruction counts: the workloads' modules the same, batches within 0.001% of 2b (BFS -0.21%), the executor alone -0.001% to +0.30%, the bank's queries -0.30% to +0.11% (four runs each; bar 1%); json_rec_time.c (cJSON, a depth-first digest compared first); CHECKPOINT's direction row through 2c

batches within 0.001% of 2a (BFS +0.36%, within its own runs' spread), the executor alone -1.3% to +0.4% (step's four cases more, mixed signs; -1.31% to +0.59% from before stage 1), the bank's queries -0.66% to +0.05% (four runs each; bar 1%); CHECKPOINT's direction row through 027's 2b

executor alone within 0.14% of stage 1, the bank's queries +0.28% to +0.80% where they hold still and +0.17% to +0.45% on average where they do not (four runs each; bar 1%): step's four cases more, not the held slots emptied each event (left to modules that hold some, the counts the same)

byte the same, the executor alone moved matmul +0.43% and BFS -0.34% (knapsack, roots, join within 0.03%; the bar of 0.1% missed, mixed signs: four cases more in step), the bank's queries -0.22% to 0.00% (bar 1%); the four cases out of line in a noinline function (b23) cost 6-15% of the executor's instructions (a call taking frame from step: the register cliff) and were taken back; CHECKPOINT's direction row through 027's stage 1

at once in integers (join 116.0 to 110.5 ms, short of 108: what is left is the same cells' memory, read, add and write again), decide's bit found once (BFS 23.2, short of 21.5: the tail's time was its loads more than its instructions), and the batch executor's loops aligned to 64-byte lines (the hot loops' placement had swung knapsack 6% at the same instructions; the lists' loops aligned too cost the bank's queries 1-2% more instructions, so not they); against b9 matmul -36%, knapsack -28%, roots -7.6%, join -6.2%, BFS -3.9%, the executor alone, the bank queries and TPC-C (+0.7%) as they were; 025's bars and what each stage measured; 024 and CHECKPOINT say so

comparisons counting their lanes): knapsack 10.07 to 8.25 ms (bar 8.6; b9 11.46, the compiled code 7.9), its instructions 12.2% below b9's; what is left of knapsack's gap is the per-batch interpretation (about 3 ms), not the kernels (ADD 1.7, GT 1.7, the masked set 0.55 ms); the others the same by instructions; make check's server_view_workers timed out once (the known flake), passed 3/3 alone and in a full rerun; bank queries' instructions within 0.1% of b9's, TPC-C -0.3%; the two large gaps left (matmul's nested rounds, BFS's candidate tail) the user's to choose

no lanes while every lane's e is the same, a list's cells once a batch): against b9, interleaved, matmul 40.01 to 25.97 ms, knapsack 11.47 to 10.07, roots 8.97 to 8.29, join 117.2 to 115.8, BFS and sort the same; sum0 8.69 to 1.01 (bar 1.5); matmul short of its bar (21): the nested rounds' interpretation (about 14 ms) and the matrices' making (4-5) were left out of the arithmetic; the executor alone and the bank queries' instructions as b9 (0.08%), TPC-C +0.7%; stage 4 next (knapsack's six passes to three)

knapsack 1.19, sort 1.37, join 2.54, words 5.58, matmul 1.85, BFS 1.61; geometric mean 1.92, from 3-300x at 6b45806), what each change did, the forms measured in assembly, the apps unchanged, what is left (text in the executor, BFS's appends, spills); CHECKPOINT says so

off the number pipes the divisions and sums wait on: roots 10.9 to 9.6 ms (1.39x C). 040 newton.c: roots' loop in the forms the tier may make it (the check as numbers 9.7 ms, in integers 8.7, none 7.7; next in r's register as gcc keeps it 7.0)

20.7 ms, pointer with multiply-add 13.1, apart 10.0, with checks 10.2, a bit tested before each load 13.4): the position's multiply and the pre-load branch cost, the checks hardly; 023 section 5 says so and what comes first (pointer induction, then a full list's copy)

apps there are): six pairs in turns, TPC-C's median -1.2% (the pairs -5.2 to +1.4%), the queries' medians within 1% but in_credit's (0.84 to 0.815 ms); the queries' instructions +0.3 to +1.5% on 49b6196 (2026-10-05-counts-49b6196.jsonl), -0.1 to +0.5% after the list's tree paths left HASHED's checks (2026-10-05-counts.jsonl). runs.sh serve, pairs and counts

lists' representation, its meaning) bare, with the checks a compiler could hoist, and with every check where the meaning puts it: hoisted 0.64-1.02x C (0.90 by the geometric mean), naive up to 12x

knapsack, sort, join, words, matmul, BFS), each against the C one would write, in one process with the same inputs and answers; PURE_AHEAD=0 to measure the code without reading ahead
