perf (ZYPERFMAP) on plain trees new/free showed recycle, new_k and own
taking about 70% of the time, mostly in calls to isobj, paylen, bdrop,
bclass and fpush and in the truth values plain code builds for && and ||.
recycle writes isobj, paylen and the class-list push out, calls scan_ptr only
for 8 or more words left, and own and new_k test with nested ifs.
frame_control grows to 22 words: a tag, &dbg and the entries of new_k,
recycle_leaf and own for the x86-64 jit's inline fast paths (next commit).

of p[-4]
the bnd recipe and paylen read n instead of the power-of-two block:
bnd: r6 = sub p 3; r6 = ld r6; r7 = xor p 0x2B7E1516; r6 = eq r6 r7;
r7 = sub p 4; r7 = ld r7; r7 = shr r7 32; r7 = mul r7 q;
r8 = mul i m; r8 = ltu r8 r7; r8 = xor r8 1; r0 = and r6 r8
paylen: return p[-4] >> 32
two loads instead of three; osize, bchk, release, recycle and the memdebug
leak report all read n (rt.new(4) has length 4, rt.new(0) has 0).
writers: new_raw and new_k set n; stack.h line 87 and tinyvm.ts (BigInt) set
it on stack segments. release clears n when a block goes into quarantine
(len 0, indexing traps; under memdebug bchk reports a use after free); every
free-list path (fpush, mkblock, bdrop, recycle_leaf, balloc hold) rewrites
the word as k << 16, and an array that grows gets a fresh block. a request over
2^31-1-HDR words stops in new_raw (oom), and the compiler only takes the
new_k fast path for constant sizes that fit, so n is never truncated.
bit users checked (all mask or preserve bits 32..62; none compares or copies
the whole word): gc mark and sweep; release, free, recycle, recycle_leaf;
share and own; isobj, quar, checkptr, obj_base; bclass and the bfree buddy
merge; balloc, mkblock, fpush, funlink, heap_grow; frame_grow; stack_allocate
in src/core/stack.h and src/js/tinyvm.ts; micro.c and core.c (check word
only); the compiler's two p[-4] | F_INTERNAL writes (base.zc, builtins.zc).
32-bit ports: none (baremetal, wasm and micro use int64 Cell).
tests: tests/programs/exactsize.zc (n-1/n for non-power-of-two sizes, new(0),
packed bytes, recycle, grow, stack growth); 8-runtime: exact_size_bounds,
pointer_index_n_minus_1, pointer_index_n_traps, pointer_index_n_traps_memdebug,
new_zero_index_traps, new_too_big_traps, stale_index_after_free_traps,
stale_index_after_free_memdebug. expectations changed: leak report shows n
(tests/test.sh line 169, examples/learn/13-memdebug.out, docs/LEARN.md,
4-statements/memdebug_report_line.zc). programs adjusted to keep test.sh
expectations: quarantine.zc (unbounded), bounds_heap.zc (rt.new(11)).
spec 3.7.4 and 4.11 updated. fixpoint 402204 words (main 402197).

run-only images
- hover: a symbol from an embedded library source (tinyvm:std.zc, tinyvm:icon.zc) was
looked up only in the document; look it up by its qualified name in the library source
(hover_embedded_sym), and render a method found that way by its line (bs_hover).
- std.capture: allocate one word more than the 256 it holds, so end() terminates inside the buffer.
- a bare call to a static function of the enclosing struct resolves like a bare struct constant
(mstruct is set for every non-generic struct's methods); the struct's own wins over a global.
- run.zc declares main untyped (fn main();), so a run-only image accepts int, void or untyped main
with both compilers.

an undefined bare name that a module exports now says which one:
"put_c is used but never defined; did you mean to include rt and use
rt.put_c?", and the import quick fix is titled the same way and marked
preferred when it is the only one, so the editor's auto-fix applies it.
hints gain quick fixes that keep the program's meaning: an unused
parameter, or a local with no other use, is renamed to _; a constant
local with one declarator becomes const; a power-of-two multiply becomes
a parenthesized shift (not when a * / or % binds its left operand); and
let p = rt.new(n) with a small constant becomes let p[n]. the hints no
longer fire for _ discards or for locals already declared const.
whole-line /* */ comments in zc sources are // comments now, and //: is
gone from the maintained sources: the notes it marked were mostly the
documentation of the declaration below, which hovers now show. section
headers are separated from the declarations after them.

the cores take their genome in with c23 #embed through src/core/genome.h,
so images are plain little-endian word files (genome.bin) instead of
generated c headers. zc0 writes that format, mkgenome checks an image
against its map and shows a compiler's diagnostics when it gets them,
and the javascript vm and the editor's vm host read the same files.
src/tools/findcc.sh picks a compiler with #embed (clang 19 or gcc 15).
zc gets an embed declaration, embed "file" as [type] name, for globals
and locals: a byte string by default, char*, numbers read little-endian,
and arrays of numbers. the compiler and language server carry their
library and source texts through it, so embed.sh and the text it
spliced into compiler.zc are gone.
make writes executables to build/bin, the default map to build/core/map,
the web page to build/web and the extension staging to build/vsix, and
the genome now rebuilds when its sources change. the test suite lays
out its own map and bootstrap and reads nothing from build/.
also: rt.put_s of a byte string in zc0 images, retained function
sources no longer count as live objects, a missing include no longer
cascades into undefined-name errors, consecutive comment lines join
into one hover paragraph, and stale test fixtures follow the include
format.

Compiler and VM
- make every memory map limit dynamic and adjustable at both build time and
runtime, including compiler tables, stacks, and every execution region
- reserve and grow tables, operand and return stacks, frame segments, and
image-building output without relocating live code or globals
- rename i/o and string helpers consistently (puts -> put_s, putn -> put_n,
scat -> cat_s) across compiler, runtime, examples, tests, and docs
- recast and consume values assigned to globals from inside functions
- allow fixed and const together, add typed closure returns (fn:t(...)),
multi-include syntax (include rt, run, core;), and recurse type inference
- never infer string literals as word, anywhere, as argument, variable, or
return type
- draft docs/BORROW.md: a borrow checker less intrusive than Rust's but more
intelligent
LSP and editor integration
- require explicit includes and give every toolchain area its own namespace
(rt, lsp, run, core)
- hover for built-in types, inferred types, values known at hover time, array
and pointer lifetime/size, library names in include statements, and inferred
lifetimes with explanations
- honor /* */ comments as documentation for variables and arguments, and stop
misattributing section headers or trailing comments as variable hints
- stream diagnostics and cancel stale requests on change
- jump to definition and references, including cross-file
- quick fixes with automatic library import, and namespace completion
Hints and diagnostics
- render hints as blue squigglies by default, with hints on/small/off per file
- suppress magic-number hints via a preceding /* */ comment, and say so
- warn on unused arguments; allow multiple _ discards in parameters, pattern
matching, and tagged enums, warning if a _ is actually used
- rewrite hint and comment prose in professional compiler-doc register
Libraries
- add icon.zc: run-time self-modification, find/replace syntax, type and block
edits, and step-through inspection of locals and globals
- add actor.zc: async actors with Actor<I,O>, implicit this, spawn/recv/send,
injected into the compiler machinery at include time rather than built in
Tooling and docs
- reorganize sources, tests, and designs into subdirectories
- unify windows entry points in tinyvm.bat and add a matching tinyvm.sh
- add --help across the toolchain
- polish the learning guide, stdlib docs, and design notes
Tests
- add accept, reject, and regression coverage across the compiler, LSP,
- runtime, icon, actors, threads, formatting, and the toolchain contracts,
plus fuzzers and property tests
