Two el_runtime portability defects only ever lived in staged local copies
used to hand-build neuron-ui PR #136's curl-enabled Windows neuron.exe.
gcc 15 promotes both to hard errors, so a clean el checkout cannot rebuild
that soul. Upstream the minimal fixes so the build is reproducible:
- http_serve_async: cast setsockopt optval to (const char*). Win32/mingw
setsockopt wants const char*, not int*; the cast is a no-op on POSIX and
matches the four already-cast sites elsewhere in this file.
- engram_save persist path: map fsync -> _commit in the _WIN32-only
el_platform_win.h (io.h already included). Windows has no fsync(); the
POSIX path is untouched.
Two independent investigations, one runtime, complementary halves:
1. Leak (Jul 2, this machine): JsonBuf buffers returned via el_wrap_str
were raw malloc, never arena-tracked — every engram_*_json call leaked
its output unconditionally. Added jb_finish() arena-tracking across all
~30 return sites. Plus el_arena_push/pop per-tick bracketing support
for the soul's awareness loop (the loop ran outside any request arena,
so even correctly-tracked allocations were permanent — 7.5GB RSS in
under a minute at 1s tick).
2. Corruption (Tim's container soak, docs findings/container-migration):
stored engram node/edge fields (content, node_type, label, tier, tags,
metadata, from/to ids) were arena el_strdup — freed at request end,
leaving dangling pointers that read back as recycled request-buffer
bytes one request later. This is the June corruption root cause and
the mechanism that grew snapshot.json to 18GB of empty-type junk
(21.6M nodes, 3,335 real). 39 sites switched to el_strdup_persist,
plus a latent double-free fix in engram_load metadata fixup.
Interaction note: fix 1's per-tick arena reclamation makes fix 2
mandatory — more aggressive arena recycling widens the use-after-free
window if stored fields still live in the arena. Apply as a pair, never
separately.
Verified live: soul + engram rebuilt from this runtime, booted against
the recovered real snapshot (3,335 nodes/40,146 edges), 5h stable at
<100MB RSS, write-then-next-request field-integrity test passes (the
June corruption fingerprint does not reproduce). engram/dist/engram
binary updated from this build.
Investigation credit: leak diagnosis this machine Jul 2-6; corruption
diagnosis + persist-fix patch by Tim's instance (docs PR #4).
ElBridge.java: Android Java companion to el_android.c — all public methods are
static, dispatches View mutations to the UI thread via runOnUiThread/CountDownLatch,
and exposes native callbacks (nativeOnClick, nativeOnChange, nativeOnSubmit).
PLATFORM_BRIDGE_SPEC.md: authoritative spec for implementing new platform bridges
(slot table contract, required __* functions, callback dispatch pattern).
detect-platforms: shell script that probes for available bridge toolchains and
prints what can be built on the current machine.
new-platform: scaffold generator that creates a new el_<name>.c with all 33
required stubs wired up.
Add seven platform bridge implementations and the shared native target header:
el_native_target.h, el_appkit.m, el_uikit.m, el_android.c, el_gtk4.c,
el_sdl2.c, el_lvgl.c, el_win32.c, el_runtime_win32.c. Each bridge implements
the 33 __widget_* C builtins declared in el_native_target.h for its platform
toolkit. el_runtime_win32.c provides a POSIX-free runtime stub for cross-compiled
Win32 targets.
Implements the accumulation layer from the Layered Consciousness architecture
(provisional 64/064,262) and answers the deferred design question. Per the spec
and Will's design: new user-facing nodes (memories, knowledge, conversations) are
created in an accumulation layer at the TOP of the consciousness stack — the engram
the user sees — while the layers below (safety, core-identity, domain, imprint,
suit) shape behavior but are hidden from the user.
- Adds ENGRAM_LAYER_ACCUMULATION (5) + the layer record in engram_init_layers
(activation_priority 50, suppressible, not injectable, transparent=0).
- engram_node and engram_node_full now assign new nodes to ENGRAM_LAYER_ACCUMULATION.
- ENGRAM_LAYER_DEFAULT stays CORE_IDENTITY ON PURPOSE: it is the fallback for LEGACY
nodes loaded from snapshots without a layer_id, so existing data (the originator
corpus) is NEVER migrated. New-nodes-only — the immutable-originator rule.
This is the foundation for fixing the identity-bleed / customer-isolation issue
(user data was landing in Neuron's core-identity layer). The retrieval-side
provenance filter (introspection should compile from accumulation, not the
originator corpus — Persona 64/036,574) is a follow-on, pending the batch-2
Layered Consciousness + Engram spec docs for exact semantics. Compiles clean.

Ports the fixes that until now lived only in the un-versioned el-sdk source the live
macOS soul was hand-built from (captured in the [DO NOT MERGE] live-darwin-runtime
snapshot) FORWARD onto main, faithfully and minimally — without dragging in the
snapshot's deletions of main's newer engram_wm_/engram_load_merge/http_serve_async.
1. UAF (hallucinated/lost-saves root cause): engram_new_id + engram_node_full now use
el_strdup_persist, NOT el_strdup. el_strdup tracks into the per-request arena that
el_request_end() frees when the creating HTTP request completes — leaving stored
nodes with dangling pointers (corrupted ids, 'saved but never listed'). Transplanted
verbatim from the live runtime; el_strdup_persist sites 19->27, matching live.
2. Atomic engram_save: write <path>.tmp, fflush+fsync, rename() over target (atomic on
POSIX) so a booting soul's engram_load never reads a truncated/0-byte snapshot — the
genesis -> nodes=1 -> 63-node-clobber loop. Plus a sparse-write floor: refuse to
overwrite a >200KB snapshot with one < 1/16 its size. (Validated in isolation:
harness 11/11; rebuilt+booted the darwin soul, round-tripped 5113 nodes, no clobber.)
The response-truncation fix is already on main (_tl_fs_read_len binary-safe length).
Compiles clean. For Will to build through CI/elb and deploy.

http_handler_fn / http_handler4_fn were defined only inside el_runtime.c, so soul
modules (routes/chat/...) that reference them via cross-module forward declarations
couldn't see the types — which broke the Windows link of every module. Moving the
public function-pointer types to the shared header is the correct home and unblocks
the build on all platforms (identical typedef, C11-safe redefinition in el_runtime.c).
With this, the soul links into a native Windows neuron.exe (mingw, static) that boots
and serves HTTP on :7770 — verified /health → 200 {"status":"alive",...} in a Win11 VM.

llm_call_system / llm_call accepted a model argument and discarded it:
they called llm_chain_call(system, user) with no model, and the legacy
ANTHROPIC_API_KEY fallback passed NULL to llm_provider_request, so every
non-agentic chat was pinned to LLM_DEFAULT_MODEL (claude-sonnet-4-5)
regardless of the caller's selection.
Thread model_pref through llm_chain_call: provider-chain entries still
honor their own NEURON_LLM_N_MODEL override and fall back to the
requested model otherwise; the legacy Anthropic path now uses the
requested model. NULL/empty preserves prior default behavior.
Effect: the soul's model selection (state soul_model / SOUL_LLM_MODEL,
e.g. claude-opus-4-8) now reaches api.anthropic.com. Previously the
chat response echoed the selected model in its label while the request
billed Sonnet 4.5.
Not built locally (no elc/cc toolchain on this checkout); needs stage CI.

Validate UTF-8 continuation bytes in jb_emit_escaped; pass valid
sequences through and escape orphaned/invalid start bytes as \u00xx.
Pre-existing change found uncommitted in the working tree; committed
here so it is reviewable rather than lost.

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.
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.
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.
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.
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.
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.
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).
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).
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.
