will.anderson a7e6fbf2d2 feat(elc, runtime): RBrace stop in parse_html_children; html_raw/html_escape; elc.c canonical
El SDK CI - dev / build-and-test (pull_request) Successful in 4m9s
parse_html_children consumed the closing `}` of the outer El function as
HTML text content when a tag was left open across a function boundary
(e.g. `page_open()` opens `<body>` without a closing `</body>`).  Fix:
stop the children loop when the current token is RBrace — that token
belongs to the El function, not the HTML tree.

Add html_raw() and html_escape() builtins to el_runtime so templates
can interpolate trusted raw HTML and safely escape user-supplied content.

Rename elc-new.c → elc.c as the canonical compiler source; rebuild
elc binary from it.

will.anderson 53e0b99d5f fix(elc): add el_mem_check() memory guard — abort before OS OOM-kill
Add el_mem_check() to el_runtime.c: reads ELC_MAX_MEM_MB (default 512),
checks RSS via getrusage (macOS bytes / Linux KB normalised to MB), prints
a clear diagnostic to stderr and exits(1) if exceeded.

Wire it into two places:
- compiler.el: upfront check at --emit-header entry point
- codegen.el: per-function check in the streaming loop after each
  el_arena_pop, so runaway growth is caught at the earliest function
  boundary rather than after the machine is already dying.

will.anderson 61bf501b84 fix: add __http_do_map_to_file runtime primitive
El SDK CI - dev / build-and-test (pull_request) Successful in 3m41s
el-install.el generates calls to __http_do_map_to_file (HTTP request
with JSON headers map, streaming response to file). Add it to both
the HAVE_CURL implementation and the no-curl stub section.

will.anderson 254cbe0ac2 fix: add __-prefixed runtime primitives expected by El compiler
El SDK CI - dev / build-and-test (pull_request) Successful in 3m22s
The El compiler generates calls to __-prefixed C primitives from within
El stdlib compiled code (e.g. __println, __str_len, __json_get, etc).
These were absent from el_runtime.c, causing linker failures when
building el-install, elb, or epm with the current compiler.

Add 46 __-prefixed aliases/implementations in el_runtime.c covering:
- I/O: __println, __print, __readline
- String: __str_len, __str_cmp, __str_ncmp, __str_alloc, __str_set_char,
  __str_concat_raw, __str_slice_raw, __str_char_at, plus numeric converters
- FS: __fs_read, __fs_write, __fs_exists, __fs_mkdir, __fs_list_raw, etc
- HTTP: __http_do, __http_do_map, __http_serve, __http_serve_v2,
  __http_response, __http_sse_* (weak stubs)
- JSON: __json_get, __json_set, __json_parse_map, __json_stringify_val, etc
- State, env, exec, uuid, sha256, args

will.anderson 60ad7f2f6b fix: align runtime function return types with El compiler output
El SDK CI - dev / build-and-test (pull_request) Successful in 3m16s
El compiler generates calls to println, print, exit_program,
http_set_handler, http_serve, http_set_handler_v2, and http_serve_v2
as el_val_t-returning functions. The runtime declared them void,
causing conflicting-type errors when el-install.c was compiled.

Change all seven to return el_val_t (side-effect functions return 0).
Also update el_runtime.h declarations to match.

will.anderson 54de7d3f3f fix: add missing runtime functions for epm.el
El SDK CI - dev / build-and-test (pull_request) Successful in 3m19s
Add native_str_to_int (El compiler alias for str_to_int) and
http_post_json_with_headers (JSON POST with additional headers map)
which epm.el generates calls to but were absent from el_runtime.c.

will.anderson 8b074d2e39 fix: normalize NaN to 'nan' in float_to_str regardless of sign bit
El SDK CI - dev / build-and-test (pull_request) Successful in 3m18s
0.0/0.0 can produce -nan on Linux/x86_64 (%g gives '-nan'),
causing the no-cycle calendar test to fail. Explicitly check isnan()
and emit 'nan' so behavior is platform-independent.

Will Anderson ec889e1e53 Add --test mode to elc with Assert stmt and full native test suite passing
Implement compile_test() entry point that emits a C test harness instead
of a normal program. Test blocks (previously skipped) now compile to
static functions with per-assertion pass/fail tracking. Assert statement
added to parser and codegen. Runtime extended with now_ns, fs_list_json,
json_build_object, json_build_array, json_escape_string, state_has,
state_get_or. Fix float negation codegen, float equality comparisons,
time_to_parts return type (JSON string), time_format empty-fmt, json_set
raw-value semantics, state_keys JSON array return. All 310 native tests
pass across 9 suites (core, text, string, math, env, state, json, time, fs).

Will Anderson 6ced0f8009 fix: double-free in engram_neighbors_json BFS + rebuild engram.c
el_strdup tracks pointers in the arena. The BFS arrays in
engram_neighbors_json are manually freed — using el_strdup caused a
double-free when the arena was later popped. Changed to plain strdup
for those allocations.

engram/dist/engram.c rebuilt from engram/src/server.el with current
elc (minor codegen diff: parenthesisation and _argc/_argv rename).

Will Anderson 3726f69435 perf: 81% RSS reduction — el_release, arena scoping, streaming codegen, libcurl stub
Chain of optimizations from swarm rounds 4-7:
- Flat stride-2 token list: eliminate per-token Map allocation (~112B each × N tokens)
- Systematic el_release() in parser.el: eagerly free intermediate parse result maps
- Per-function and per-statement arena scoping in codegen_streaming()
- Streaming codegen pipeline: parse one fn at a time, emit C, discard AST
- HAVE_CURL guard: elc CLI binary drops libcurl, eliminating SSL/TLS init overhead
- HTML codegen parts-list: O(n) instead of O(n²) string growth for nested templates
- Batch c_escape: str_slice clean runs instead of char-at per byte

Result: 33.4MB → 6.5MB RSS on web/src/main.el (-81%). Self-host: PASS.

Will Anderson eb52be4ade runtime: add EL_TRUE/EL_FALSE macros and scoped arena for CLI
Adds EL_TRUE/EL_FALSE convenience macros to el_runtime.h alongside the
existing EL_NULL, making boolean-returning builtins readable without
raw (el_val_t) casts. Documents all value macros in the header comment.

Also lands el_arena_push/el_arena_pop — a scoped string arena for CLI
programs that never call el_request_start/end. The compiler can push a
mark before a compilation unit and pop it after to free intermediate
strings, reducing peak RSS during long compile runs.
