src/compiler/compiler.zc is now twelve files under src/compiler/, listed in
order in src/compiler/parts. cat of the parts in order is byte-identical to
the old file, so every compiler and image except the language server's is
unchanged. no function was edited.
consumers read the list: the makefile, bootstrap-check, genmap (which still
writes one compiler.zc into a generated map directory), tinyvm.bat,
test.sh, test_win.ps1 and the lsp drivers. the language server embeds each
part and serves them joined as the one document tinyvm:/compiler.zc.

src/tools/parity.sh compiles each program of tests/programs, examples and
examples/learn with zc0 (runtime, program, mkgenome, a microcore with the image
embedded, kept under build/parity/) and runs it beside build/bin/zy < prog.zc,
then compares stdout. what zc0 rejects is skipped and counted. tests/parity.known
lists the differences that are by design (zc0 has no ownership analysis or
memdebug checks). make parity runs it. tests/programs/parity_ops.zc pins operator
precedence and associativity across every binary operator, unary operators,
assignment and short-circuit order; its output matches a c compiler's.

embed declarations get accept and reject fixtures, a run-only image check
through zc0, an lsp keyword hover and the grammar keyword. errors point at
the declaration and still declare the name, so its uses are not reported
again. zc0 tracks byte-string globals and lays embedded arrays out one word
per element, the way its own indexing reads them.
the command-line javascript vm reaches node's file system for the file
syscalls, so include and embed work there; other embedders opt in.
the web build is self-contained in build/web with its examples. README,
BORROW and BOOTSTRAP-OWNERSHIP describe the new build and ownership rules,
and ONBOARD.md is a reading and verification order for the code.
the suite passes the map header to mklayout, the wasm fuzz program uses
the include format, and lsp drivers scale their deadlines on hosts
without the arm64 jit (ZC_TEST_TIMEOUT_SCALE). LLVM_CONFIG selects an
llvm with headers for the llvm section.

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.

src/ carried 8.4 MB of build output: the genome header, the javascript vm and
its layout, and the language-server image, plus a second copy of the extension
server under editors/vscode/server/. none of it is source.
- move the genome from src/core/genome.h to build/core/genome.h and compile with
-Ibuild/core; `make all` bootstraps one when it is missing
- write genome.json, layout.ts, layout.js and lsp.json to build/js/
- compile tinyvm.ts to build/js/, typed by a tracked src/js/layout.d.ts so the
vm needs no generated file beside its source
- build the wasm server into build/editors/vscode/server/ and stage the whole
server into editors/vscode/server/ only while mkvsix.sh packages it
- redirect the test suite, image_run.js, tinyvm.sh, tinyvm.bat, test_win.ps1 and
the baremetal build at the new paths, and add make lspimage and make vsix
- stop tracking every generated file
also fix a build blocker: lookup_raw compared skind against K_VAR, which was
never declared, so `make genome` could not run at all. the guard is about
emitted program globals, which are K_GVAR and K_GARR.
tests/test.sh -q reports 159 passed and 21 failed both before and after this
change; every failure is pre-existing and comes from the checked-in genome being
stale relative to src/, plus the bootstrap above.

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
