http://git.yeowoo.org/pure/atom?h=master2026-10-18T23:40:55Z027's 4f-4: loops nested to any depth: the load counts a module's deepest 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);

one text; one number, dt; one u32, the item's position, the table its view), one frame input at most; a handler's event its input's number; no DT or TEXT_INPUT (97 opcodes now 95, FIELD reads dt and the text), pure_app_input, frame, tick, text and point, pure_module_position, PureEdge or an app's ticks: every event is pure_app_message, saved after it unless deferred; pure-run sends each command's message to the input bound so (a release or a frame no input takes still an event, clearing the fault, so the workbench parity holds) and defers a stored app's saves past frames as before; pure-serve posts a press with its key's release, refuses timers, frames and pointings (no_input) and ticks timers as messages; holes closed: the tier found a handler's input by the old numbering, reading a message's number field as another input's (aup's numbers caught it), and serve's replies_borrow did too; module-probe presses as messages; unit tests: the test modules' builder (expand) writes the old shapes as bound messages, pointing over a pointing input and its table, stored frames deferred as a host defers them, a press's handler refused a FIELD; counts: b35 against b34 with batches BFS +0.03%, the rest within 0.001%, without batches BFS +0.12%, join +0.01%; the bank's queries (s34 on the 4c aup's module, s35 on 4d's, six each in turns) field -0.23%, found -0.14%, large -0.12%, in_credit +0.11%, the rest within 0.06%;

the load holds an anchor in a text as a cursor and in a list as an index (a mark in a list refused) and each anchor instruction as the runtime's own one for it (PURE_OP_CUR_*, PURE_OP_INDEX_*, numbered past a module's in module-run.h with the kept lists' steps; a module holding one refused), so the executor's, the batches' and the JIT's steps are those they were; the verifier holds MOVE, COUNT and AT to the text or list they name; new: AT in a text (a cursor so many characters or lines from its start, not_found past the end); COUNT's lines from 0; unit test anchors (AT and COUNT in a text, AT in a list, four refused); the tests' modules written with the anchor instructions; counts: b34 against b33 with batches matmul -1.36%, the rest within 0.08%, without batches within 0.04%; the bank's queries (six each, s33 on the 4b-2 aup's module) in_credit +0.28%, per_branch +0.23%, ranks +0.10%, the rest 0.00%; 008 and 0272026-10-18T19:01:08Zeunhhunecpition205@gmail.com2026-10-18T19:01:08Zurn:sha1:936c08e3424c606855051ee86f25a7df0f162c62Module executor and pure-serve: 027's 4a, a message's rows holding lists: 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;

each call has its own stack and locals and its own of what the function's code names (held values empty, the event's lists empty, registers bound to none), the caller's as they were when it returns; a function's code is a handler's but for a message, CALL in handlers and functions alone, and a walk around a call keeps to the lists the callee (or what it calls) changes; calls nest as deep as the event's room allows, each frame's bytes counted there (memory) and its block's length as work; the functions' table in the header's last u16 and after the handlers (a block, parameters and results) with their signature items (a record field's type, 5 bytes); run_calls, run_batches' steps with frames in the app's blocks that never move (a CALL opens one, a RETURN closes it, a stop closes all), an event's lists calls let go kept for the next; a value held by a slot the callee has its own of copied to the arena as it crosses; held values of the payload, the arguments or the constants held as they are (nothing copied until appended to); the JIT leaves blocks with calls or list locals to the executor; local type 4 (a list value, its record in bits 16-31); CHAR_AT (104, the code point beginning at a byte position of a text) and CHAR (105, a code point's text: limit outside 0-0x10FFFF, encoding for a surrogate); and a hole closed: LOOP and EACH open on a stack holding their operands alone (a loop's block begins at the bottom of its run's stack: a verified module with values below a loop crashed the executor, 62 below and 64 in its block); unit tests (fib, a tree summed by a walk that calls itself around its register, each call's own list and held text, a list through a local, characters and their faults, a call without end failing as memory and as work with nothing changed, 11 refused; under ASan and UBSan too)2026-10-18T15:05:34Zeunhhunecpition205@gmail.com2026-10-18T15:05:34Zurn:sha1:a9adaf2a1a62e5dd37f0067653b35e9cfa2c1860Batch plans, stage 1 of design 025: each batch loop's block read once at load (pure_batch_plans, after its instructions' plans are final): the locals it sets and whether it sets items, its sums into cells, and at each instruction a role (a sum's again, add or set) and how far on a LOCAL_LOAD's x = x op e is; batch_run, pass and local_load read the plan instead of scanning the block each batch; PURE_BATCH_LANES to build other lane counts; PURE_BATCH_CHECK (a build flag, while the stage is made) reads the block again each batch and stops if the plan differs; seeds 1 2 3 5 23 (default and PURE_SELECT=all), the fixed sources and the unit tests pass with it2026-10-08T13:51:46Zeunhhunecpition205@gmail.com2026-10-08T13:51:46Zurn:sha1:042dbfd98d664d67dcb006f1870984fc97bfebe1PURE_REUSE_KEPT a define: as an enum constant UINT32_MAX is past int, which clang -Wpedantic refuses2026-10-08T13:24:44Zeunhhunecpition205@gmail.com2026-10-08T13:24:44Zurn:sha1:bb02dbb078e5a1780d4e6864e3bd73886a3e260bBatch: general cuts (docs/research/131). A value computed by the same code as an earlier one in a line of the block (nothing between setting what it reads: planned at load, reuse_from and reuse_length) is taken from the earlier, kept for it; if !c { ... } one branch the other way, no NOT; an arm whose lanes are a quarter or fewer runs in those lanes alone (a selection: outer values gathered by sel, reductions into their lanes around, locals set given back masked at its end, stores and sums expanded, appends and a filter's kept rounds by sel; PURE_SELECT=all every straight arm, 0 none); a list whose keys are bits asked by them in one loop of lanes, a filter decided by its bits and bits of our own (no hash set; a key with no bit is not there); L.first + i affine while within the list; a slice's two bounds in one call (pure_list_slice); a filter's kept rounds copied from numbers made once.

Keys kept as bits (pure_list_bits) asked by a loop of lanes, fields of a DENSE list found at their keys (pure_list_dense); an outer lane's affine value in four bytes.

A frontier walk of the suite's graph (each node's edges' to summed) PURE_JIT=0 55.2 to 10.4 ms (the compiled code 6.24). module_tier makes guarded loops with a walk in each (seeds 1, 2, 3, 5, 23 alike: 8,819 spread and 7,651 together in seed 23's); FRONT_SOURCE2026-10-06T10:09:18Zeunhhunecpition205@gmail.com2026-10-06T10:09:18Zurn:sha1:4cb98b7beb83278e33a5577b9e83239eca403187
