reconcile(release-runtime): Windows-port + complete v1.0.0 release runtime so the desktop soul cross-compiles

The desktop soul (neuron/dist) compiles against the v1.0.0-20260501 release runtime. After #66 landed the engram natives (tokenized/ranked search, engram_prune_telemetry) and #79 the durable truncation fix into this runtime, two gaps remained before it could cross-compile the Windows brain: 1. Windows OS boundary: the release runtime had no Win32 path. Ported the same _WIN32-guarded shim the mainline runtime carries (#69): #ifdef _WIN32 -> el_platform_win.h (winsock/dlsym/popen + WSAStartup ctor), SOCKET fd guards and el_closesocket() at every socket site, CreateProcessA for exec_bg, the tm_zone/mingw guard, an el_setsockopt optval wrapper (GCC14), and curl-less libcurl stubs. Every change is _WIN32/HAVE_CURL-gated — the POSIX build is byte-identical (gcc -fsyntax-only clean; native behaviour unchanged). 2. Header exports: the release el_runtime.h omitted symbols the soul dist calls that are defined in this runtime's .c — the http_handler_fn/http_handler4_fn typedefs and el_arena_push/pop, engram_prune_telemetry, engram_get_node_by_label. Declaration-only, POSIX-neutral; fixes implicit-declaration/unknown-type errors under the C11 mingw build. Result: x86_64-w64-mingw32-gcc compiles el_runtime.c + all 48 soul modules clean; POSIX gcc -fsyntax-only clean. This is the Windows-port PR the runtime needed on main (the release-runtime counterpart to #69), landed via stage.
Merge #79 : durable HTTP response-truncation fix, both runtimes (via stage)

+# El Compiler Release v1.0.0 — 2026-05-02
+
+## Components
+- `bootstrap.py` — El language compiler (Python, recursive descent parser, emits C)
+- `el_runtime.c` — El runtime (C, HTTP server, engram, DHARMA, LLM chain)
+- `el_runtime.h` — Runtime public API header
+
+## Changes in this release
+
+### Critical bug fixes
+- `state_set`/`state_get` are now thread-safe (pthread_mutex). Was racing across 64 worker threads.
+- `looks_like_string` threshold raised from 1,000,000 to 4GB. Unix timestamps were being dereferenced as heap pointers.
+- `fs_read` guards against negative `ftell` result (pipe/special file overflow).
+
+### Engram architecture (major)
+- Two-layer activation: `background_activation` (Layer 1, broad fan-out) + `working_memory_weight` (Layer 2, executive filter)
+- Inhibitory edges: `EngramEdge.inhibitory` flag suppresses working memory promotion without affecting background activation
+- Suppression memory: `suppression_count` — nodes activated-but-suppressed accumulate pressure toward breakthrough
+- Temporal decay: `temporal_decay_rate`, `created_at`, `last_activated_at`, `activation_count` on EngramNode
+- Per-type activation thresholds (Safety: 0.05, Canonical: 0.15, Lesson: 0.25, Note: 0.40)
+- Temporal range query: `engram_query_range(start_ms, end_ms)`
+- Layered consciousness: `EngramLayer` struct, `layer_id` on nodes and edges, `EngramStore.layers[]`
+- Layer 0 override pass: safety layer fires last and cannot be suppressed

will.anderson	ff577391f2	reconcile(release-runtime): Windows-port + complete v1.0.0 release runtime so the desktop soul cross-compiles El SDK CI - dev / build-and-test (pull_request) Successful in 7m7s Details The desktop soul (neuron/dist) compiles against the v1.0.0-20260501 release runtime. After #66 landed the engram natives (tokenized/ranked search, engram_prune_telemetry) and #79 the durable truncation fix into this runtime, two gaps remained before it could cross-compile the Windows brain: 1. Windows OS boundary: the release runtime had no Win32 path. Ported the same _WIN32-guarded shim the mainline runtime carries (#69): #ifdef _WIN32 -> el_platform_win.h (winsock/dlsym/popen + WSAStartup ctor), SOCKET fd guards and el_closesocket() at every socket site, CreateProcessA for exec_bg, the tm_zone/mingw guard, an el_setsockopt optval wrapper (GCC14), and curl-less libcurl stubs. Every change is _WIN32/HAVE_CURL-gated — the POSIX build is byte-identical (gcc -fsyntax-only clean; native behaviour unchanged). 2. Header exports: the release el_runtime.h omitted symbols the soul dist calls that are defined in this runtime's .c — the http_handler_fn/http_handler4_fn typedefs and el_arena_push/pop, engram_prune_telemetry, engram_get_node_by_label. Declaration-only, POSIX-neutral; fixes implicit-declaration/unknown-type errors under the C11 mingw build. Result: x86_64-w64-mingw32-gcc compiles el_runtime.c + all 48 soul modules clean; POSIX gcc -fsyntax-only clean. This is the Windows-port PR the runtime needed on main (the release-runtime counterpart to #69), landed via stage.	2026-07-22 15:56:08 -05:00

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 Details 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.	2026-07-22 15:04:25 -05:00

The stage and prod release jobs reported FAILURE even when the el-runtime-c/-h publish SUCCEEDED, because the ancillary ci-base Docker rebuild (a CI-cache optimization on the fragile host-mode GCE runner) reddened the whole job. - Rebuild ci-base step: continue-on-error: true — never blocks/reddens the job; the SDK publish is the deliverable. - Publish step: set -euo pipefail + empty-key guard + active-account echo so a real publish failure still fails loud and is diagnosable.	2026-07-15 16:14:50 -05:00

will.anderson	8ce8656de2	epm: declare cross-module callees as extern fn so strict compilers accept generated C El SDK CI - dev / build-and-test (pull_request) Successful in 7m33s Details epm's sibling modules (registry/install/update) call functions defined in other modules and in the El runtime (config, read_installed, registry_find, manifest_deps, manifest_name, registry_latest_version, registry_token, install_vessel, installed_version) without importing them, so elc emits no C prototype for those calls. gcc<=13 treated the resulting implicit declarations as warnings; gcc>=14 and clang reject them as hard errors, which is why the "Build epm" CI step fails and blocks the whole dev/stage pipeline. Add `extern fn` forward declarations -- El's own separate-compilation mechanism -- for each cross-module callee at the top of registry/install/update. This gives elc the correct C prototype in every generated translation unit, so the calls compile cleanly and still resolve at link time. Simply suppressing -Wimplicit-function-declaration would be unsafe: an implicit int return truncates the 64-bit pointer returns of config/registry_find into a latent crash, so declaring the true signatures is the correct fix. Localized to epm; touches neither elc nor the runtime.	2026-07-15 10:14:43 -05:00

will.anderson	4773dd0aa2	runtime: make Windows soul reproducible from a clean el checkout El SDK Release / build-and-release (pull_request) Failing after 16s Details 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.	2026-07-15 04:24:08 -05:00
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 Details 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.	2026-07-15 04:07:33 -05:00
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).	2026-07-14 18:48:16 -05:00
