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

examples/json_tree.aup: a variant, lists in records, match, appends into a field's list, number(t)) and walked for a digest, against Python's reading: JSONTestSuite's 95 y_ taken alike, no n_ taken, 6 i_ taken; 300 random nested documents alike; in make check (module_specs, the suite and 100 random documents, three paths); 167 lines against the same design's 133 in Python (the bar missed: the type declarations), 40 times cJSON's time and 1.3 times plain Python's (556 ns a byte, 525 instructions); json_tree.py, json_tree_time.c (cJSON linked, digests compared first)

examples/json.aup, 80 lines against the same design's 90 in Python): JSONTestSuite's 95 y_ cases taken and 188 n_ refused, 21 of the 35 i_ taken, the three paths alike, in make check (module_specs, the 316 small cases in tests/specs/json under their MIT license, the two large ones made and hashed); 116 times C's time and 1.2 times plain Python's (299 ns a byte, 339 instructions); && and || made to decide alone (writing it, i < n && d[i] read past the end) with AND and OR kept where the right side cannot fail, every other module byte for byte the same; SHA-256 again with formats and joined bytes, 42 lines and 159 times C

examples/sha256.aup) right for FIPS 180-2's examples and 138 more messages on every path, in make check against hashlib; 52 lines against Python's 28 (the bar missed: no formatting, no bytes joined or sliced, no lists as values, moved into stage 2), 176 times C's time and 0.43 of plain Python's (1,591 ns a byte; a block's 19,129 instructions, 39% of them the inlined fn's literals not folded); 044's check, time.c against the same algorithm in C (digests compared first) and the Python reference

typed value built of bool, i64, number, bytes (text the UTF-8 ones), records, variants and lists of anything (an unkeyed list keyed by position), anchors for cursors and indexes; functions that may recur and while, ending by the budget as EVM's gas (the module the unit of determinism); bit operations on integers as infinite two's complement within i64; folds left folds in meaning, reordered by the implementation only for the same answer; meaning apart from representation; answers to 026's suspects; five stages (bytes, bits and lists of numbers for SHA-256; nesting, variants, recursion and characters for JSON; nested state stored; patterns gathered; the number model) with bars
