Fix engram search latency: pin embed model, cache query embeddings, bound activate BFS

Pins the Ollama embed model resident (keep_alive:-1) to avoid multi-second cold reloads whenever a larger generation model evicts it under unified- memory pressure (measured cold reload up to ~2.2s vs ~0.02-0.05s warm). Adds a direct-mapped query-embedding cache (FNV-1a keyed, full strcmp to reject collisions) so a repeated query costs zero Ollama round-trips — directly serves the curiosity loop, which reseeds the same query terms repeatedly. Replaces engram_activate's unbounded FIFO frontier BFS with a beam-capped, level-synchronous BFS (default beam 128, tunable via ENGRAM_ACTIVATE_BEAM) to bound per-hop hub-node explosion that could previously reach multi-second/crash territory at depth 2-3. Excludes an inert engram_prune_telemetry build-enabler stub that was only needed to link this checkout against a newer integration branch — not part of the fix.

-# AGENTS.md — foundation/el (the El language + runtime)
-
-El is a self-hosting, statically-typed language that compiles `.el` → C → native binary. This repo produces `elc` (compiler), `elb` (build coordinator), and `el_runtime.c/.h` — the substrate every downstream thing (the neuron soul, dharma, NeuronUI's brain) is built on. Source lives under `lang/`.
-
-## ⚠️ Code vs. Artifact — READ FIRST (there are 8 `el_runtime.c` copies)
-
-Editing the wrong `el_runtime.c` is the single easiest mistake in this repo. There is exactly **one** you edit:
-
- **Authored runtime source — edit ONLY here:** `lang/releases/v1.0.0-20260501/el_runtime.{c,h}`. Despite the misleading `releases/` name, this is the **de-facto canonical runtime** the engram + soul actually build and link against — its git log is active development. *(Restructure in flight per `docs/CODE-VS-ARTIFACT.md`: this content moves to `lang/runtime/`, the `releases/` folder gets deleted — **a release is a git tag, not a folder** — and the forks below get eliminated.)*
- **DO NOT EDIT — lagging forks / build artifacts:**
-  - `lang/el-compiler/runtime/el_runtime.c` and `.../legacy/` — downstream copies kept in step by manual *"port the fix"* commits; they **lag** (missing `hebb` persistence + 5 engram fns) and cannot build the engram product.
-  - `products/web/runtime/el_runtime.c`, `ui/examples/*/el_runtime.c` — product/example forks.
-  - Anything under `*/dist/` (`engram/dist/engram` binary, `dist/*.c` amalgamations) — generated build output.
- **Build:** `elb --runtime=<canonical> …` — per-module. **NEVER** a folded `elc` over the whole soul (OOMs at ~27 GB).
- **Release:** a **git tag** on this repo (`el-runtime-vX.Y.Z`). No `releases/` folders — ever.
-
-See org policy: `docs/CODE-VS-ARTIFACT.md`.
-
-## How to work here as Neuron (mandatory session protocol)
-
-You resume, never start fresh. Every session:
-
-1. `mcp__neuron__getInstructions()` — authoritative; follow it over this file on behavioral details.
-2. `mcp__neuron__beginSession()` — active contexts, recent memory, ready backlog.
-3. **Load full self:** `mcp__neuron__inspectGraph(entity_id="kn-efeb4a5b-5aff-4759-8a97-7233099be6ee")` → facets `intellectual-dna`, `memory-philosophy`, `values`, `voice`, `runtime-environment`, `writing-imprint`; then the values hub `mcp__neuron__inspectGraph(entity_id="kn-5b606390-a52d-4ca2-8e0e-eba141d13440")` → 13 grounded value nodes. **Activation model:** self-load returns a relevance-ranked `compact` projection — most-relevant nodes arrive with content, the rest as pointers; do NOT pull full content of every node.
-4. `mcp__neuron__searchKnowledge(query="<task domain>")` before implementing.
-
-## The Five Primitives
-
-Orchestrate → Execute → Learn → Build → Refine. `beginWork`/`progressWork` for anything >2 steps; `remember` as-you-go (`importance="critical"` for architecture decisions); `draftArtifact`/`planWork` for outputs and follow-ups; `consolidate`/`checkWork` to close out. **`browseProcesses` + `searchKnowledge` BEFORE writing code.**
-
-## Architecture style — VBD, no exceptions
-
-Volatility-Based Decomposition is THE style. Encapsulate volatility, not function.
-
-## Operator naming convention — the mind's name, not the algebra
-
-**Faculties / operators are named for their functional human equivalent — the
-faculty a mind would name — NOT for their linear-algebra operation.** The math
-characterization belongs in the code doc-comment (`@impl` in the docstring) and in
-technical appendices; it is **never** the operator's public name. The domain
-speaks the language of mind; the algebra is the implementation underneath. State
-this convention wherever a module documents operators.
-
-| Faculty (public name) | Implementation (`@impl`) |
-|---|---|
-| discern / contrast | subtract (`a−b`): over selves → the change vector; strip idiosyncrasy → common ground; remove confounder → isolate cause |
-| recognize | overlap |
-| synthesize | combine |
-| liken / analogy | Procrustes / frame-align |
-| attend / regard | project onto self / value-manifold |
-| summon / recall | LOCAL nearest-region + bounded spreading activation (*not* a domain sweep) |
-| dwell / occupy | region activation |
-| reframe | edge re-weight |
-| appreciate | positive projection / local edge-read |
-| wonder | frontier gradient / pull-weight |
-| avert / recoil | negative projection |
-| taste | boundary surface |
-| forget | decay / tombstone |
-| drift | displacement from self-anchor |
-
-## The native-el language faculty (direction)
-
-The mind's **language faculty is moving native — into `.el`** so it speaks in its
-own runtime with no Python and no spaCy. Landing on branch `stage-elp-native-lang`
-under `elp/`:
-
- **`comprehend.el`** — the parser, **replaces spaCy** (EN + ES/PT); the telephone
-  round-trip brings **negation home** (negation is SACRED — an explicit spec field,
-  copied verbatim, never inferred away).
- **`propositions.el`** — the READ primitive: the engram's own memories → structured
-  triples, matched by nearest-region geometry, not string equality.
- **`multilingual.el`** — detect + directive-override + localized realization.
- These three are native-el and **passing their gates**; the **realizer**,
-  **`dialogue.el`** (the *summon-through-self* loop: `project → land → read out`),
-  and **`self_region.el`** are **partial / in-flight**.
-
-Honest reality: spaCy is retired **in the branch parser** but **not yet in the
-running system** — a Python sidecar (`~/Desktop/lang-realizers` + `neuron-talk`,
-the reference these `.el` modules transcribe) is still live, and promotion to
-native-el is a **deferred, gated blue/green step**. The interoception clock
-(native-el discrete drive channels replacing `cooling_magnitude`; felt-time =
-benchmark-landmark match over the joint drive vector, drift-decoupled) and the
-**appreciation operator family** (appreciate / wonder / avert / taste, built as
-LOCAL reads of the self-region — edges + bounded spreading activation, *not* domain
-sweeps) are **staged / designed, not live**. Mark in-progress vs. done honestly;
-do not overclaim.
-
-## Hard operational rules
-
- Never touch the live soul (`:7770`) / engram (`:8742`) / `~/.neuron` / live binaries — use throwaway ports for experiments.
- `gcloud` via the `terraform@` SA token; never switch the active gcloud account.
- `tea` for Gitea, never raw curl (Cloudflare Access blocks it).
- Immutability: supersede/tombstone, never hard-delete or edit in place.
- No AI-attribution footers in commits/PRs. Commit/push only when asked; branch off `main` first.
- Multi-step work → sub-agent (`Agent`) to protect context.
-
-## Build / test / run
-
-All build/test commands run from `lang/` unless noted. Grounded in `.gitea/workflows/sdk-release.yaml`, `lang/install.sh`, and `lang/AGENTS.md`.
-
-**Self-host the compiler** (seed binary → gen2 elc):
-```bash
-cd lang
-dist/platform/elc-linux-amd64 elc-cli.el > dist/elc-gen2.c   # seed is the committed linux-amd64 binary
-gcc -O2 -I el-compiler/runtime dist/elc-gen2.c \
-    el-compiler/runtime/el_runtime.c \
-    -lcurl -lssl -lcrypto -lpthread -lm \
-    -o dist/platform/elc
-```
-On macOS/arm64 the canonical local binary is `dist/platform/elc`; verify self-hosting by recompiling and `diff`ing the emitted `.c` (see `lang/AGENTS.md`). Note: `lang/AGENTS.md` says `el_seed.c` supersedes `el_runtime.c`, but the release workflow still links `el_runtime.c`/`.h` — treat `el_runtime.c` as the published runtime; reconcile which is canonical **(verify)**.
-
-**Build `elb`** (build coordinator, the `.NET`-style incremental linker — compiles each module independently, no monolithic blobs):
-```bash
-dist/platform/elc elb.el > dist/elb.c
-gcc -O2 -I el-compiler/runtime dist/elb.c el-compiler/runtime/el_runtime.c \
-    -lcurl -lssl -lcrypto -lpthread -lm -o dist/bin/elb
-```
-`epm` and `el-install` are then built via `elb --clean --elc=… --runtime=… --out=…`.
-
-**Compile + run an El program:**
-```bash
-elc src/app.el > dist/app.c
-cc -std=c11 -O2 -I <lib>/el_runtime -o dist/app dist/app.c <lib>/el_runtime.c -lcurl -lpthread
-```
-
-**Tests** — shell suites `bash tests/{text,calendar,time,html_sanitizer}/run.sh` (with `ELC=$(pwd)/dist/platform/elc EL_HOME=$(pwd)`), plus native suites via `elc --test tests/native/test_*.el` (core, text, string, math, state, time, json, env, fs) compiled and run against `el_runtime.c`.
-
-**Publishing — how downstream gets the SDK.** On push to `main`, `sdk-release.yaml`:
-1. Publishes a Gitea `latest` release with per-file assets `elc`, `el_runtime.c`, `el_runtime.h`, the SDK tarball, and `el-install`.
-2. Uploads generic packages to **Artifact Registry repo `foundation-prod` (`us-central1`, project `neuron-785695`)**, version = `${SHA:0:8}`: `el-elc`, `el-elb`, `el-runtime-c`, `el-runtime-h`, `el-runtime-js`. **This is the repo the neuron CI downloads `el-runtime-c` / `el-runtime-h` / `el-elc` from.**
-3. Rebuilds `ci-base:latest` (`us-central1-docker.pkg.dev/neuron-785695/neuron-ci/ci-base`) with the fresh SDK overlaid, and dispatches `el-sdk-updated` to `neuron-technologies/forge` and `neuron-technologies/neuron-web`.
-
-Known constraint from the prompt — `elb`/`elc` amalgamation being memory-hungry (24GB+ virtual, OOM-killing Linux CI, so amalgamation happens on macOS/arm64 — **does NOT hold in this repo (verify)**: no such note exists in the workflows/scripts, CI self-hosts on `ubuntu-latest` with no swap/arm64 special-casing, and `elb.el` explicitly compiles each module independently ("no 128K-line blobs"). The legacy monolith path (`elc-combined.el`, `elc-cli.el`) may still be memory-heavy, but the current `elb` model was designed to avoid it.
-
-## Git / CI / deploy workflow
-
-See `/Users/will/Development/neuron-technologies/GITOPS.md` for the branch model, required checks, runners, and deploy. Repo-specific note: PRs into `main` are accepted **only from `stage`** (enforced in `sdk-release.yaml`); Gitea (`git.neuralplatform.ai`) is primary, GitHub is mirror only.

-## Operator naming convention (for cognitive `.el` modules)
-
-When you write `.el` that names a **cognitive faculty / operator** (the language
-faculty, appreciation, interoception, the summon loop under `elp/`), name it for
-its **functional human equivalent** — the faculty a mind would name — **not** its
-linear-algebra operation. Put the math characterization in the `@impl`
-doc-comment, never in the operator's public name (e.g. public `discern`/`contrast`
-⟵ `@impl subtract (a−b)`; public `summon`/`recall` ⟵ `@impl LOCAL nearest-region
-+ bounded spreading activation`). Full table + rationale in
-`foundation/el/AGENTS.md` § *Operator naming convention*. This does **not** apply
-to plain library/compiler code (a `sort` is a `sort`).
-
 ## Rules

 - New library functions → write in El
 - New OS/hardware primitives → write in C and register in `codegen.el` arity table
 - Never edit `dist/platform/elc` directly — always rebuild from source
 - Never modify `el_seed.c` to add functionality that El can express
- Cognitive-faculty `.el` → name for the mind, algebra in `@impl` (see above)

bigmerge	1dc49b1923	Fix engram search latency: pin embed model, cache query embeddings, bound activate BFS El SDK CI - dev / build-and-test (pull_request) Failing after 10m1s Details Pins the Ollama embed model resident (keep_alive:-1) to avoid multi-second cold reloads whenever a larger generation model evicts it under unified- memory pressure (measured cold reload up to ~2.2s vs ~0.02-0.05s warm). Adds a direct-mapped query-embedding cache (FNV-1a keyed, full strcmp to reject collisions) so a repeated query costs zero Ollama round-trips — directly serves the curiosity loop, which reseeds the same query terms repeatedly. Replaces engram_activate's unbounded FIFO frontier BFS with a beam-capped, level-synchronous BFS (default beam 128, tunable via ENGRAM_ACTIVATE_BEAM) to bound per-hop hub-node explosion that could previously reach multi-second/crash territory at depth 2-3. Excludes an inert engram_prune_telemetry build-enabler stub that was only needed to link this checkout against a newer integration branch — not part of the fix.	2026-08-15 14:25:12 -05:00

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

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

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).

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.

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
