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);

a module's transient and counted states are flags of each, the lists views and functions change or name sets of states (state_words words, a bit each), the verifier's walked lists a list with its length, duplicate names found by sorting them; an app's eighteen arrays of each state (values, texts, lists, the stored lists' slots, the last save's and the burst's, a reader's, an event's values and marks) in one block sized to its module, a replace laying the new module's apart and taking it once nothing can fail; the runtime's lists placed past any state (PURE_LIST_HEARD 0x10000), their slots after the states'; a snapshot's arrays sized so too; pure_app_read false without room (pure-serve then shows none); a save's drafts, values and the tree's revisions on the stack for 64 states, else on the heap; the JIT compiles modules of 32 states at most (its sets a word), the app's lists read through a pointer; a view reads the app's values as they are (no state changes in one), no copy of 32 a evaluation; unit test: 300 states loaded and the last counted; a hole closed: pure_app_stop read the arrays a failed start never laid; PureApp 4,256 bytes, not 8,504; counts: b39b against b38 with batches within 0.06%, without batches knapsack +0.49%, join +0.23%, the rest within 0.17%; the bank's queries (s38 and s39b in turns, three each) field -1.99%, found -1.18%, in_credit -1.10%, large -0.99%, the rest -0.58% to +0.11% (the first build, s39, copied a view's values at run time's size: in_credit +2.4%);

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 format and executor: 027's 4b-1, a record field holding bytes (type 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 0272026-10-18T17:52:48Zeunhhunecpition205@gmail.com2026-10-18T17:52:48Zurn:sha1:e8b3499289022c8729900a58ed218d961a85fec8Module executor: a kept list's lists through steps of their own (027's stage 3): the load gives ITEM_GET and ITEM_SET of a kept list's list field, and LIST_APPEND, LIST_INSERT and APPEND_IN of a kept list whose record holds lists, numbers past the module's (OP_KEPT_*, after verifying and planning: no module holds them, the JIT leaves their blocks to the executor), so the instructions' own steps are as before stage 3; the list module holds a list field's value as bytes (PURE_CELL_LIST only in images' headers and layouts) and text_field is a text's alone again: the stage 3 commit had cost BFS 1.4% of its instructions with batches and 1.7% without (its millions of appends asking each field twice), the five works now within 0.04% of before it2026-10-18T16:45:16Zeunhhunecpition205@gmail.com2026-10-18T16:45:16Zurn:sha1:d5f0cac74721863a91b0a799256b62c0b7b2a3c1Module format and executor: 027's stage 2c, functions and characters: a function is a block CALL runs (102), its parameters the stack it begins with and RETURN (103) its results on top, which take the arguments' place; 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:a9adaf2a1a62e5dd37f0067653b35e9cfa2c1860Module format and executor: 027's stage 2b, lists in records: a record field of type LIST (its items' record in its default) holds a list the event made, its number an i64 in the cell (0 an empty one), so lists keep their inside, batches and the JIT as they were (the JIT's append fast path leaves such records alone); LIST_VALUE (a copy of an event's list, nothing made for an empty one), LIST_BIND (a register, an event's list flagged PURE_LIST_BOUND, read and walked, never changed by code), APPEND_IN (an item into the list in a field of an event's list's item, copied first when another value shares it or a register is bound to it), sharing counted where cells take them; such records only in event lists (no stored, transient or message list, no key); the event's lists go as each event or view's body begins, registers given back their own; record field names may be paths (at.x: records in records, flattened by aup); NUM_PARSE (a text written as a JSON number, its nearest double, core's pure_parse_number); unit tests (values copied, shared then appended, a bound register seeing what it was bound to, three events alike, 6 refused; under ASan and UBSan too, which found the record kinds' missing LIST)2026-10-13T06:40:30Zeunhhunecpition205@gmail.com2026-10-13T06:40:30Zurn:sha1:8481b12fb794690cce0d9c54032ffba3de1fe31dJIT: books written back only for lists their nest keeps books of: a nest with no room left for a list's headroom kept its live count anyway (in x30, the 13th register) and wrote that stale count over the list's own after its appends went the unbooked way (a loop of appends after a doubly nested loop reading t.has, PURE_JIT=all: e.count 1 for 36)2026-10-06T02:57:14Zeunhhunecpition205@gmail.com2026-10-06T02:57:14Zurn:sha1:17bdd42a0e6633747b163984c4e68313f5356f66JIT: an append to a HASHED list in a nest whose books keep DENSE appends' growth in registers checks the memory against the books' headroom (the app's growth lacks theirs until written back): it faulted MEMORY a round late, its work a round more than the executor's (a loop appending to DENSE, FLAT and HASHED lists, memory 6000: 3562 for 3525). pure-run: memory N, the states' budget2026-10-06T02:46:11Zeunhhunecpition205@gmail.com2026-10-06T02:46:11Zurn:sha1:e1c8812473c89b96e9c1a09f3a46f8f392945b64
