will.anderson 7aa847e32a Merge origin/dev into engram-tiered-storage
El SDK CI - dev / build-and-test (pull_request) Failing after 10m51s
Resolve 3 conflicts:
- lang/el-compiler/runtime/el_runtime.c: keep deletion (deprecated runtime fork;
  single-source-of-truth is lang/runtime/, enforced by scripts/check-single-runtime.sh).
- lang/releases/v1.0.0-20260501/el_runtime.h: keep deletion (releases/ is a generated
  artifact folder, not a source path; a release is a git tag, not a folder).
- lang/runtime/el_platform_win.h: union of dev's Windows port (#80: setsockopt optval
  wrapper + curl-less libcurl stubs) and our fsync(->_commit) shim needed by engram_store WAL.

Nothing in dev's build consumes the deprecated fork or releases/ folder.

will.anderson bb64a236ed engram tiered storage: engram-service wiring + elc fold-hang fix + prune-store mirror
- Wire paged store into the ENGRAM SERVICE (server.el, the authoritative durable
  owner): boot->engram_store_boot, persist_canonical->engram_store_checkpoint,
  gated by ENGRAM_STORE.
- elc (lang/elc.c + src/parser.el + codegen.el + elc-combined.el): OOB guard in
  tok_kind/tok_value + parse_block progress backstop — fixes the pre-existing
  unbounded-memory fold hang on sessions.el.
- engram_prune_telemetry mirrors ISE prune to the store (store_forget) so store
  live-count tracks resident and stale telemetry stays bounded.
- Deployed live 2026-08-12: engram :8742 on neuron.egm+WAL, count reconciled 11552.

will.anderson 0a72fced28 engram: WAL persistence + integrity hardening + single canonical runtime
El SDK CI - dev / build-and-test (pull_request) Failing after 13m17s
Establish lang/runtime/ as the ONE canonical el runtime (from the active
runtime that carries hebb/emb persistence + the new WAL); repoint the el CI
publish, engram build, elb default, and in-repo build scripts to it; delete
the el-compiler/runtime + lang/releases/ forks; add scripts/check-single-runtime.sh
drift guard.

Fixes a live prod bug: the el CI published el-runtime-c/-h from the LAGGING
el-compiler fork (0 hebb refs), so the shipped soul never persisted Hebbian
edge weights — learned co-activation was wiped on every restart. Publishing
from canonical ships the stranded 'learning that cannot outlive the process'
fix.

WAL storage engine + integrity fixes (DELETE->tombstone + store-layer
protection, safe data-dir default) ride in behind ENGRAM_WAL (default off =
byte-identical to today). Verified: engram elb per-module build clean, WAL
gate 66/66, native smoke ok, drift-guard green.

will.anderson 23552ed40a make the el-compiler runtime compile again
The loopback/API-key hardening carried in this file since 2026-07-15 called
el_http_request_authorized and el_http_send_401 from http_worker with no
forward declarations, so the calls were implicit and the later static
definitions conflicted. The file did not build. Two prototypes fix it.

Worth naming the pattern: uncommitted work is invisible to every check that
would have caught this. Three weeks of desktop security hardening was neither
committed nor compiling, and nothing reported either fact.

will.anderson 6838e5cbff port the \uXXXX UTF-8 decode fix to the el-compiler runtime copy
Same defect as the release runtime: \uXXXX was skipped and a literal '?'
emitted, destroying every non-ASCII character in JSON entering the runtime.
Two copies of one parser bug is how this class of fault survives a fix, so
it lands in both.

NOTE: this file also carries pre-existing uncommitted work from 2026-07-15/16
that this commit preserves rather than authors - loopback bind hardening
(EL_HTTP_BIND_HOST) and per-install API-key auth (EL_HTTP_AUTH_KEY) for the
shipped desktop build, plus goal-bias and node-json changes. It had been
sitting in the working tree for three weeks. Committing it because
uncommitted work is work that does not survive, which is the same durability
lesson as yesterday's Hebbian write-back finding. It needs review on its own
terms - see the backlog item for reconciling the two runtime copies.

will.anderson 43636aed99 runtime: pair fs_read length hint with its buffer in BOTH runtimes — kill response truncation for good
El SDK Release / build-and-release (pull_request) Failing after 7s
The binary-safe fs_read length (_tl_fs_read_len) was consumed by the HTTP
response path for ANY body, even when a handler wrapped a smaller file into a
larger reply. Content-Length then lied AND the send stopped short: the
safety-contact (988) routes returned 178 of 208/218 bytes, cut mid-'set_at' —
unparseable JSON. The desktop app read that as failure. On Windows the shipped
brain is an OLD build without even the per-handler workaround, so EVERY reply
truncated: the app can't read confirmations and refuses the new user.

Durable fix: pair the length hint with the exact buffer pointer it describes
(_tl_fs_read_buf). Apply the raw byte count ONLY when the response IS that
buffer (binary file serving stays correct); every wrapped/enveloped/derived
body is measured with strlen. Reset both at request start and in fs_read /
json_get_raw. This also closes the stale-hint heap over-read (a length larger
than a later body would read past it out the socket) that a plain max() leaves
open — so this class of bug dies on every platform, not just where a handler
happened to be patched.

Applied identically to the mainline runtime (lang/el-compiler/runtime) AND the
frozen release runtime (lang/releases/v1.0.0-20260501) the desktop souls
compile against — the release copy still carried the raw leak, which is why the
Windows brain kept truncating. Same proven approach as PR #78 (Tim Lingo),
extended to cover the release runtime and rebased onto current main.

Both runtimes: gcc -fsyntax-only clean.

will.anderson 4773dd0aa2 runtime: make Windows soul reproducible from a clean el checkout
El SDK Release / build-and-release (pull_request) Failing after 16s
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.

will.anderson 6b9d9e6c4a Add engram_get_node_by_label runtime native to unblock soul link
El SDK Release / build-and-release (pull_request) Failing after 22s
chat.el calls the runtime native engram_get_node_by_label to fetch
well-known nodes (conv:history, session:summary) by stable label rather
than by ID — immune to vector-index drift across restarts. The current
runtime never defined it, so the regenerated dist/soul.c fails to link.

Backport the function verbatim (idiom-adapted to jb_finish) from release
runtime v1.0.0-20260501 and register it as an EL builtin exactly like its
siblings: runtime definition + prototype, __-prefixed seed wrapper +
prototype, and codegen arity entry. No search-site code is touched.

will.anderson b4967af13e feat(engram): semantic search layer via nomic-embed-text (cosine ∪ lexical)
Lexical istr_contains alone can't surface a node whose words don't appear
in the query. This adds an optional dense-vector layer: node content and the
query are embedded through Ollama (nomic-embed-text), and nodes are ranked by
cosine similarity unioned with lexical hits, so a paraphrase query reaches the
right node.

Wired into all three query entry points in el_runtime.c:
  - engram_search_json (HTTP /api/search): collect lexical ∪ semantic
    candidates, score (lexical base 1.0 + cosine; pure-semantic = cosine),
    rank, emit top-N. Stable sort preserves old order when semantic is off.
  - engram_search (internal el_val twin): lexical ∪ semantic union.
  - engram_activate seed loop (HTTP /api/activate): a node seeds if it
    lexically matches OR clears the cosine threshold; pure-semantic seeds
    enter scaled by cosine so paraphrase spreads without overpowering.

Degradable by design: the whole layer is gated on HAVE_CURL plus a one-shot
runtime probe. If curl is compiled out, Ollama is unreachable, or
ENGRAM_SEMANTIC=0, every entry point yields zero semantic signal and callers
fall back byte-for-byte to the pre-existing lexical search.

Node embeddings are cached in process memory keyed by node id with an FNV-1a
content hash for invalidation; the query is embedded once per call — so the
graph is not re-embedded on every query. nomic task prefixes
(search_query:/search_document:) are applied for retrieval separation.

Build steps gain -DHAVE_CURL so the engram artifact compiles the layer in
(-lcurl was already linked). Env: ENGRAM_SEMANTIC, ENGRAM_EMBED_URL,
ENGRAM_EMBED_MODEL, ENGRAM_SEMANTIC_MIN (cosine threshold, default 0.6).

will.anderson e3dabe3e08 fix(engram): tokenized + ranked lexical search, not whole-query Ctrl-F
El SDK Release / build-and-release (pull_request) Failing after 14m46s
engram search/activate/goal-bias matched the ENTIRE raw query string as a
single case-insensitive substring (istr_contains(field, q)). Multi-word
queries like "windows msi signing" only matched a node containing that exact
contiguous run, so real multi-word queries returned ZERO on a graph saturated
with the answer. This is Ctrl-F, not search — and search is the core of the
engram being useful.

Fix: split the query on whitespace into distinct tokens; a node matches if it
contains ANY token in content/label/tags. Rank by distinct tokens matched
(desc) then salience (desc). istr_contains is kept unchanged as the per-token
primitive. Single-token queries are a strict special case (score 0 or 1) so
the many single-word callers do not regress.

Sites changed (all in el_runtime.c):
- new helpers engram_tokenize_query / engram_node_match_score / engram_rank_cmp
- engram_search           (internal el_val_t path)
- engram_search_json      (HTTP /api/search path)
- engram_activate seed loop (HTTP /api/activate path; seed activation scaled
  by token coverage so full-query matches seed more strongly)
- engram_goal_bias overlap bonus upgraded to graded token coverage

Proof (6591-node snapshot copy, rebuilt binary on :8799, POST JSON path):
  windows msi signing  0 -> 20   Will Anderson  0 -> 20
  windows msi          0 -> 20   tokenized search fix  0 -> 20
Single-word parity preserved (VBD/volatility/elc capped at limit; unkey = all
matching nodes). Top hits are relevant (e.g. "Will Anderson" surfaces the
Project Design and VBD whitepapers).

Note: GET ?q=a%20b still returns 0 because query_param (server.el) does not
URL-decode — a separate EL-layer bug; the soul's POST-JSON path is fixed here.

will.anderson 0a0a2bcb44 parser: bound token reads to Eof so malformed input errors instead of OOMing
El SDK Release / build-and-release (pull_request) Failing after 16s
Out-of-range tok_kind/tok_value reads returned runtime null (el_list_get OOB
-> 0) rather than the Eof sentinel, so the inner parse loops (parse_block,
call-arg, array-literal, match-arm) that terminate only on their close
delimiter or k=="Eof" never saw Eof once the cursor ran past the single
trailing Eof token. On unclosed-delimiter input the parser then appended AST
nodes forever -> unbounded allocation -> ~700GB -> OOM (observed compiling
neuron/sessions.el).

Fix at the choke point: tok_kind returns "Eof" and tok_value returns "" for
out-of-range positions, restoring the parser-wide contract that reads at/after
the end yield Eof. expect() no longer steps past the Eof sentinel on mismatch.
This terminates every overrun loop simultaneously; a malformed program now
surfaces as a normal (best-effort) parse end instead of exhausting memory.

Requires a self-hosted bootstrap rebuild of elc to take effect.

will.anderson f78da81aa4 runtime: fix the memory leak + write-corruption pair in el_runtime.c
El SDK Release / build-and-release (pull_request) Failing after 11m58s
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).

Tim Lingo 18e1ab6db1 feat(engram): add accumulation layer (layer 5) — new nodes default to it, not core-identity
El SDK Release / build-and-release (pull_request) Failing after 12m23s
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.

Tim Lingo 2dec76c87a fix(runtime): reconcile live data-integrity fixes onto main (UAF + atomic engram_save)
El SDK Release / build-and-release (pull_request) Failing after 17s
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.

Tim Lingo a36a62ca14 fix(el-runtime): promote http_handler typedefs to el_runtime.h (cross-module + Windows)
El SDK Release / build-and-release (pull_request) Failing after 13m0s
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.

Tim Lingo dbf2c659d9 fix(runtime): pass model through to the LLM API instead of dropping it
El SDK CI - stage / build-and-test (pull_request) Failing after 12s
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.

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.

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 5f9cad5908 fix(elc): eliminate OOM in --emit-header by using token-level signature scan
The --emit-header path previously called parse() which builds the entire
program AST in memory before writing the .elh file. For checkout.el (~491
lines with HTML template trees and deep BinOp string-concat chains), this
exhausted memory before the header could be written.

Fix: replace parse() + emit_header() with scan_fn_sigs_el() +
emit_header_from_sigs(). The new path tokenises the source once, then
walks the flat token list skipping over function bodies entirely — peak
memory is O(tokens) instead of O(whole-program AST).

New functions in parser.el:
- scan_type_el: reads a type annotation and returns its El source string
- scan_params_el: reads (name: Type, ...) and returns El params string
- scan_fn_sigs_el: token-level scan that collects El-style fn signatures
  without building any expression AST nodes

New function in compiler.el:
- emit_header_from_sigs: writes .elh from scan_fn_sigs_el output

Self-hosting check: elc compiled with new elc, diff of outputs is
identical (zero difference).

Smoke test: elc --emit-header checkout.el produces correct three-entry
.elh (previously truncated at two entries due to mid-parse OOM).

will.anderson f971e96dd5 fix(parser): str_join separator '' not ' ' — CSS selectors were emitting spaces between tokens

will.anderson a3732a1e9a fix(parser): add {#if}/{#else}/{/if} support and raw-text <style>/<script> in HTML templates
El SDK CI - dev / build-and-test (pull_request) Failing after 18m3s
The El lexer silently skips '#', so {#each} lexes as LBrace Ident:"each"
and {#if} lexes as LBrace If ... (using the If keyword token, not Hash).
The existing {#each} check used k2=="Hash" which was dead code.

Parser changes (parser.el):
- Add parse_raw_text_content(): collects all tokens as raw text until
  </tag_name>, bypassing El expression parsing. Used for <style> and
  <script> elements so CSS/JS content isn't parsed as El expressions.
- parse_html_element(): use raw-text mode for <style> and <script> tags.
- parse_html_children(): fix {#each} detection (k2=="Ident", k3=="each"
  instead of dead k2=="Hash" check). Add {#if cond}...{#else}...{/if}
  support generating HtmlIf AST nodes.

Codegen changes (codegen.el):
- Add cg_html_if(): generates if (cond_c) { then_c } else { else_c }
  for HtmlIf nodes.
- cg_html_parts(): dispatch HtmlIf to cg_html_if.

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.

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 bd7303447b fix: skip test blocks in codegen to prevent OOM on test files
test "name" { ... } blocks were not recognized by the self-hosted
compiler. The body { } was parsed as a Map literal, creating a huge
AST with O(n²) string concatenation in the toplevel_exec_stmts loop
(which had no arena scope). A 272-line test file would consume 400MB+
and a 720-line file importing the full compiler source caused 150GB
usage and crashed the machine.

Two fixes:
1. Skip Test tokens in codegen_streaming before parse_one() —
   advance past "name" and skip_to_rbrace on the body block.
   Test blocks are never compiled; self-hosted compiler has no test runner.

2. Add per-statement arena scope to toplevel_exec_stmts emission loop,
   matching the el_main_body loop. Frees intermediate strings after
   each statement to prevent O(n²) accumulation from any unrecognized
   construct that reaches that path.

Result: test_string.el (272 lines, 27 test blocks): 0MB peak (was 400MB+).
        test_compiler.el (720 lines + 8728 imported): 15MB peak (was 150GB).

Will Anderson e8f6765750 fix: arena leak in compile() — token/sig strings now tracked
Wrapped compile() body in el_arena_push/pop so the arena is active
before lex() and scan_fn_sigs(). Previously both ran with
_tl_arena_active=0, leaking all token and signature strings permanently.
Also prevents inner pop(mark=0) calls from deactivating the arena
between per-function scopes. Verified: self-host PASS, RSS stable.

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 ee86736eab merge round-4-delta: flat stride-2 token list + str_char_code dispatch + batch c_escape
- Flat token list: lexer emits [kind0, val0, kind1, val1, ...] instead of [{kind,val}, ...]
  Eliminates per-token ElMap allocation (~112B × N tokens)
- str_char_code hot loop: char classification via Int codes, no strdup per char
- Batch c_escape: str_slice clean runs instead of char-at per byte
- Parser updated to use tok_at/tok_kind/tok_value stride-2 accessors

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.

Will Anderson e587bedf30 round-3-gamma: combine c_escape + scan_interp_string batching — max round-3 savings
Combines two orthogonal optimizations:
1. c_escape batching (from alpha): ASCII runs emitted as str_slice segments instead
   of one str_char_at string per byte. O(N) allocs → O(K) where K = special chars.

2. scan_interp_string batching (from beta): char dispatch via str_char_code (Int)
   + clean_start tracking to flush plain runs as str_slice. Eliminates per-char
   string allocations in the string-literal scanning hot path.

Result on web/src/main.el: 14.5MB -> 13.4MB peak RSS (-7.6%).
Self-hosting: PASS.
2026-05-05 16:01:05 -05:00
Will Anderson 1eef9928f4 round-2-gamma: combine flat token list + char code dispatch — max round-2 savings
Combines two orthogonal optimizations:
1. Flat token list (from beta): lex() returns [Any] with alternating kind/value
   pairs instead of [Map], eliminating one ElMap per token (~3 mallocs each).
   Parser updated: tok_kind(t,i) = t[2*i], tok_value(t,i) = t[2*i+1].

2. Char code dispatch (from alpha): lex() hot loop uses str_char_code -> Int
   instead of str_char_at -> strdup String for all character classification.
   Eliminates ~400K x 16B = 6.4MB of temporary string allocations.

scan_digits and scan_ident also updated to use str_char_code.

Result on main.el: 17.1MB -> 14.4MB peak RSS (-16%).
Self-hosting: PASS.
