ingest: unify transduce_prose/transduce_structured into one transduce()

transduce() is now THE single mechanism: one function, no content-type
branch inside it. It never asks whether `source` is prose, JSON, or
raw/opaque bytes (audio, etc.) — it runs one algorithm unconditionally:
split on "\n\n" as a universal boundary-marker check, and if that finds
no boundary, fall back to fixed 4096-char windows. Same node/edge wiring
(root -contains-> chunk, chunk -precedes-> next, "#"-prefixed chunk gets
a heading/section_of link) regardless of what's inside a chunk. Dedup is
the existing find_existing_by_content path via merge_manifold, applied
uniformly. The old transduce_structured JSON dataset/records/feature-node
interpretation is deleted outright, not just unused — a JSON file now
gets chunked and deduped like anything else, with no pre-computed
structure. All five ingest_* entry points still exist unchanged in name
and role; ingest_file/ingest_dir/ingest_url/ingest_llm now call the one
transduce() (ingest_stream builds its own turn-nodes directly and never
called either old function, so it's untouched).

This unlocks raw/opaque content (audio, or anything else with no natural
text/JSON shape) without any DSP, LLM call, or external API: transduce()
chunks it exactly like it chunks anything else. There is zero semantic
understanding of audio (or any payload) claimed or built here — any
meaning is expected to emerge later from Neuron's own existing mechanisms
(embedding, spreading activation, dedup) acting on this real geometry
over time.

Two small C builtins added to el_runtime.c/h (fs_size, fs_read_b64_chunk)
because El strings are NUL-unsafe under strlen-based ops and fs_read()'s
result silently truncates at the first embedded NUL, which is routine in
real binary/audio bytes. ingest_file compares fs_read()'s string length
against a real fs_size() stat() count; on mismatch it rebuilds the
payload as base64-encoded fixed 3072-byte windows read directly off disk
(binary-safe in C, verbatim, no invention), joined with the same "\n\n"
marker transduce()'s boundary scan already looks for. This is a
mechanical fidelity fix, not interpretation of content — transduce()
never learns a fallback happened. Registered both builtins' arity in
codegen.el; did not rebuild the elc compiler binary itself (unrelated,
pre-existing gap: self-hosting elc via el_seed.c fails on this worktree
independent of this change, reproduced with codegen.el reverted) — the
existing elc binary compiles calls to unregistered builtins via its
already-existing arity=-1 passthrough, confirmed by an actual clean
`elc ingest.el` + `cc` build against the modified el_runtime.c.

INGEST_KIND keeps existing only as an acquisition-mechanism selector
(dir/file/url/llm/stream — which RPC to use to fetch bytes), not as a
content-type flag; the redundant "structured" value (an alias for "file"
that hinted the now-deleted JSON branch) is removed. ingest_dir drops its
file-extension filter for the same reason: transduce() takes anything now.

Verification: local manifold construction confirmed correct against a
real captured audio file (will_clean.wav, 304288 bytes, and a 12288-byte
real prefix slice) — exact expected node/edge counts both times
(101 nodes/199 edges full file; 5 nodes/7 edges for the slice, matching
ceil(bytes/3072)+1 nodes and 2n-1 edges), with real, verbatim base64
content confirmed decoding back to the actual WAV header bytes. Compiles
clean via the real elc + the modified el_runtime.c/engram_*.c (built and
booted an actual sandbox engram off this exact source with `nsbx create
--branch`).

NOT verified this session, disclosed rather than papered over: end-to-end
server-confirmed persistence (a real before/after /api/stats delta, and a
fetched node by id) for the audio, prose, and JSON-fixture cases. Every
local nsbx sandbox engram tried tonight (two stock pre-#109 binaries
hitting the known O(N*D) brute-force scan bug, then a fresh #109/HNSW
binary built from current dev) took minutes-to indefinitely long on the
final /api/load-merge write's embedding step and hit the client's 60s
HTTP timeout before responding, even for a 5-node write. This is
confirmed as real (if slow) forward progress, not a hang: the sandbox's
WAL file was observed growing steadily across every attempt. The code's
own pre-existing HONESTY GATE correctly refused to report success in
every case, returning "load-merge failed: ..." with a
"nothing below this manifold was confirmed persisted by the server" note
instead — exactly as designed. This is an environment/infrastructure
limitation, not a defect introduced by this change: the engram server
binary itself is untouched by this commit.

+# 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)
+
+> **`elp/` is the EL Projector** — Neuron's efferent (expression) organ: the one
+> native realizer that *projects* understanding onto a surface via
+> `plan(frame) → realize(spec, profile)`, where a **surface is a profile**. **Language
+> is one profile among many** (text, speech, music, image, voice/accent transforms) —
+> the flagship, and the focus of this section. Projection, not diffusion: generation
+> *from* an owned, understood signature — never the averaging of a stolen corpus.
+> *(ELP formerly "EL Language Processor"; renamed EL Projector 2026-08-15.)*
+
+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.

+# El
+
+**A self-hosting, statically-typed language that compiles to C — built around a graph-native runtime instead of a database driver.**
+
+El is the execution substrate for the Neuron agent runtime, the DHARMA network, and the Engram knowledge graph. This repository is the monorepo for the whole stack: the language itself, the graph memory engine it's built to talk to natively, and the tools (package manager, IDE, UI framework, diagramming) built on top of it.
+
+---
+
+## Why El exists
+
+Every other language treats persistent, associative state as something you reach for through a driver — a SQL client, an ORM, a Redis library bolted on from outside. El inverts that: graph operations (`engram_*`) are runtime primitives, on the same footing as string or list operations. There is no separate database driver because the database is not separate.
+
+El has four defining properties:
+
+1. **Self-hosting compiler.** The compiler (`lexer.el`, `parser.el`, `codegen.el`, `compiler.el`) is written in El. It compiles El source to C, which `cc` compiles against a fixed runtime into a native binary. A Rust genesis compiler bootstrapped the first iteration; the self-hosted binary at `lang/dist/platform/elc` has been the canonical compiler ever since — every binary in `dist/platform/` was produced by an earlier version of itself compiling `el-compiler/src/`. The chain is auditable: source is the ground truth, not the binary. See [lang/BOOTSTRAP.md](lang/BOOTSTRAP.md) for the full recovery path if that binary is ever lost.
+2. **C compilation target.** Every compiled program is plain C11. Every El value is `el_val_t` (`int64_t`); strings are heap pointers cast through it. Functions become C functions; top-level statements become `main()`.
+3. **Graph-native runtime.** The runtime provides first-class graph operations over an in-process Engram store — no separate DB driver, no ORM.
+4. **DHARMA-aware identity.** A `cgi` block declares a program's DHARMA identity at compile time. The runtime resolves identity before user code runs, so `dharma_*` calls have a stable principal and channel surface throughout.
+
+---

+
+`lang` is the foundation — the compiler and C runtime everything else builds on. `engram` is the graph-native memory/state engine that gives El its identity (property 3 above). Everything else is either a tool for working with El (`epm`, `ide`) or a system built on top of Engram's graph model (`elp`, `ql`, `ui`, `arbor`).
+
+---
+
+## Repository layout
+
+### [lang/](lang/) — the El language
+
+The compiler and runtime. Self-hosting: `elc-cli.el` → `compiler.el` → `lexer.el` / `parser.el` / `codegen.el` / `codegen-js.el`, textually inlined and compiled in one pass. Compiles to C11 and links against `el-compiler/runtime/el_seed.c`, a hand-maintained OS-boundary layer (libcurl HTTP, pthreads, filesystem, arena allocation) — everything else in the runtime is native El (`runtime/*.el`).
+
+Two layers to know: **El programs** (`.el` files — where nearly all work belongs) and **the C seed** (`el_seed.c` — edit only for genuine OS-level access; never re-implement what El can already express).
+
+Current status (single source of truth: [lang/spec/language.md](lang/spec/language.md)): lexer/parser/codegen and the C runtime's core (I/O, strings, math, lists, maps, filesystem, args) are implemented. In flight: `%` operator, match-statement codegen, `?` nil-propagation, `cgi` block parsing + DHARMA identity resolution, VBD role enforcement (`@manager`/`@engine`/`@accessor`), the real `engram_*` and `dharma_*` runtimes (currently stubs), and libcurl-backed `http_get`/`http_post`/`http_serve`. Bitwise operators, `??`, and `as` casts are explicitly **not** in this language.
+
+Key docs: [AGENTS.md](lang/AGENTS.md) (agent-facing orientation), [BOOTSTRAP.md](lang/BOOTSTRAP.md) (compiler recovery from scratch), [spec/language.md](lang/spec/language.md), [spec/codegen-js.md](lang/spec/codegen-js.md).
+
+### [engram/](engram/) — graph intelligence substrate
+
+**A local-first memory substrate for accumulating intelligence**, and the reason El's runtime doesn't need a database driver. Rust core (`engram-core`, `engram-ffi`) exposed to El and other languages (Kotlin, TypeScript/WASM, Go bindings).
+
+The model: retrieval is **spreading activation**, not query. You name seed nodes and a query embedding; activation propagates outward through weighted edges, attenuating multiplicatively per hop (`strength = parent_strength × edge_weight × target_salience × cosine_sim`), gets pruned below a threshold, and the top-N nodes by activation strength come back. Storage and retrieval are the same structure — the way long-term potentiation works in biological memory, not the way a relational or vector database works.
+
+Nodes live in four tiers (Working / Episodic / Semantic / Procedural, mirroring prefrontal / hippocampal / neocortical / cerebellar memory) and migrate between them based on **salience decay** — `importance × recency-decay × log(activation_count)`. Forgetting is adaptive pruning, not a bug: unreinforced memories stop competing for attention without being deleted.
+
+Backed by `sled` (embedded, local-first, no daemon) with flat cosine scan for vector search — deliberately simple until scale demands an HNSW layer. Full API and design rationale in [engram/README.md](engram/README.md).
+
+### [elp/](elp/) — Engram Language Protocol
+
+Bidirectional engine mapping between Engram semantic forms and natural-language surface text, across **31 languages** — from Spanish and Japanese through historical/liturgical languages (Old Norse, Sanskrit, Sumerian, Coptic, Akkadian, Ge'ez). Compilation order runs `language-profile` + `vocabulary` → per-language `morphology-*` → `grammar` → `realizer` → `semantics` → `elp`. This is what lets an Engram graph node round-trip to and from readable text in any of those languages.
+
+### [epm/](epm/) — El Package Manager
+
+Manages **vessels** (El's package unit): publish, install, resolve dependencies. Vessels are stored in Engram as graph nodes, not files in a registry index — `epm` reads the local `manifest.el`, talks to Engram over HTTP, and writes resolved vessels to `.epm/vessels/`. Source: `registry.el`, `install.el`, `update.el`, `manifest.el`.
+
+### [ide/](ide/) — El IDE
+
+Three vessels: **el-ide-server** (HTTP backend — file ops, build/run, LSP bridge, plugin host, settings), **el-lsp** (the language server — completion, hover, diagnostics, outline, format, type graph), and **el-plugin-host** (first-party plugin lifecycle: install/remove/enable/disable). `ide/projects/` and `ide/examples/` hold sample projects, including the canonical `hello-friends` first-program walkthrough.
+
+### [ql/](ql/) — engram-el
+
+The El-native integration layer for a *live* Engram server — not a library (no importable modules, no build artifact), a set of standalone `.el` programs run directly via `el run-file`. Three components: **Studio** (`studio/studio.el`, a full terminal graph explorer), a **Hebbian field-model** proof of concept, and El builtin / LLM-builtin smoke test suites. This is the reference for correct patterns when an El program uses Engram as its substrate. Spec: [ql/spec/elql.md](ql/spec/elql.md).
+
+### [ui/](ui/) — el-ui
+
+A frontend framework where **component state is an Engram graph and reactivity is spreading activation** — not virtual-DOM diffing (React), Proxy-based dependency tracking (Vue), or compile-time analysis (Svelte). Re-renders are activated and propagated the same way associative memory retrieval works in `engram/`.
+
+~15 vessels covering the full frontend surface: `el-platform` (env/fs/network/clock abstraction), `el-config`, `el-html` (SSR emit primitives), `el-layout`, `el-style` (design tokens/themes), `el-i18n`, `el-auth` / `el-identity` (JWT, sessions, OAuth PKCE — Engram-native), `el-services` (REST/gRPC/WebSocket bindings), `el-aop` (`@authenticate`/`@authorize`/`@cache`/`@rate_limit` decorators), `el-secrets`, `el-graph` (graph rendering/editor), `el-publish` (App Store / Play Store automation), and `el-ui-compiler` (El→JS component compiler; currently a stub pending a JS backend in `elc`). Spec: [ui/spec/framework.md](ui/spec/framework.md).
+
+### [arbor/](arbor/) — diagram language
+
+A `.arbor` diagram language and toolchain: `arbor-core` (NodeId/shape/edge-kind types), `arbor-parse` (recursive-descent parser), `arbor-diagram` (IR + Mermaid serializer + architecture-diagram builders), `arbor-layout` (hierarchical layout — rank assignment, positioning, group bounds), `arbor-render` (SVG renderer), `arbor-cli`. (The architecture map above is the kind of diagram this is for.)
+
+---
+
+## Getting started
+
+Install the El SDK from the latest release:
+
+```bash
+bash lang/install.sh
+# EL_VERSION=v1.0.0   bash lang/install.sh   # pin a specific release tag
+# EL_PREFIX=/opt/el   bash lang/install.sh   # custom install prefix
+```
+
+Or build the compiler from source and verify the self-hosting chain:
+
+```bash
+cd lang
+./dist/platform/elc elc-cli.el > elc-new.c
+cc -std=c11 -I el-compiler/runtime -lcurl -lpthread \
+   -o dist/platform/elc-new \
+   elc-new.c el-compiler/runtime/el_seed.c
+
+# Confirm the new binary reproduces itself exactly
+./dist/platform/elc-new elc-cli.el > elc-verify.c
+diff elc-new.c elc-verify.c   # should be identical
+
+mv dist/platform/elc-new dist/platform/elc
+```
+
+Run your first program:
+
+```bash
+./lang/dist/platform/elc lang/examples/hello.el > hello.c
+cc -std=c11 -I lang/el-compiler/runtime -lcurl -lpthread \
+   -o hello hello.c lang/el-compiler/runtime/el_seed.c
+./hello
+```
+
+More examples in [lang/examples/](lang/examples/), including a full starter project at `lang/examples/hello-project/`.
+
+If the compiler binary is ever lost or corrupted, [lang/BOOTSTRAP.md](lang/BOOTSTRAP.md) is the authoritative recovery path.
+
+---
+
+## Development workflow
+
+Branching follows `dev → stage → main`: work lands on `dev`, promotes to `stage` for integration testing, and is promoted to `main` for release (visible directly in the git history of this repo). CI is defined per-subproject under `.gitea/workflows/` — `lang`/`epm`/`ide` share the root pipeline; `engram` and `ql` carry their own (`ci-dev`, `ci-stage`, and a release workflow each).
+
+- Language/runtime specs live at `*/spec/*.md` (`lang/spec/`, `ql/spec/`, `ui/spec/`) and are the single source of truth for implemented-vs-planned status — code and docs are expected to agree with the spec's status markers, not the other way around.
+- Agent-facing orientation guides live at `*/AGENTS.md` (currently `lang/AGENTS.md`); more subprojects may grow their own as they need agent-specific conventions documented.
+- Tagged releases live under `lang/releases/`, each with its own `RELEASE.md`.

+Wiktionary — real gender, real inflections) instead of the demo/curated subsets
+the prototypes shipped.
+
+## ELP before this branch
+- 18 classical/ancient languages fully done (vocab + morphology + tests):
+  akk ang cop egy enm fro gez goh got grc non peo pi sa sga sux txb uga.
+- 11 modern/classical languages had `morphology-<code>.el` in the build manifest
+  but **no vocabulary and no lang_profile**: es fr de ja ar he hi ru fi sw la.
+- The ES port (`stage-elp-es-port`) had a *demo-scale* vocabulary-es.el (~350
+  entries, s-expr form).
+
+## Landed on this branch (full-lexicon seed-fn format, matching the 18 ancients)
+Vocabulary schema per row: `[lemma, pos, form0, form1, form2, en_gloss, hint]`.
+Files are ELP runtime **seed data** (loaded via the Engram at runtime), so — like
+all 18 classical `vocabulary-*.el` — they are intentionally NOT in the build
+manifest. Syntax validated: the chunked `fn vocab_<code>_seed_pN` format
+compiles cleanly to C via `elc` (correct UTF-8).
+

+|**total**|            |**812,894**    |       |        |        |     |
+
+Generators (reproducible): `elp/tests/lang-gen/gen_elp_seed_full.py` (Romance),
+`gen_elp_seed_de_la.py` (German declension + Latin case-paradigm mapping). They
+read the pre-built morph caches in `~/Desktop/lang-realizers/data/` (UniMorph +
+kaikki), which are too large to commit.
+
+## Remaining (honest)
+Of the 11 ELP backfill targets, 4 are done (es fr de la). The other 7 have **no
+full-lexicon engine** yet — cannot be generated honestly without engine work:
+- **ru**: only a 110-entry curated Slavic subset exists; full `rus.unimorph`
+  present but no `morphology_ru_full` productive loader. Needs a full Russian
+  morphology module (like the Romance ones) before vocab generation.
+- **ja / ko / zh**: validated demo engines (~66-104 hardcoded words) in
+  `lang-poetry-experiment`, Python only. Agglutinative (ja/ko) + isolating (zh)
+  need `.el` engine ports + full-lexicon wiring (ja: jpn_unimorph; zh: CC-CEDICT).
+- **ar / he (Semitic)**: template engines (16 AR / 8 HE patterns, ~6 roots) in
+  `~/semitic_engine`, Python only. Root-and-pattern; full UniMorph ara/heb
+  present but used only for validation. Needs productive root lexicon + `.el` port.
+- **hi (Hindi), fi (Finnish), sw (Swahili)**: `morphology-<code>.el` exists in
+  ELP but there is NO scattered prototype and NO downloaded data for these —
+  full-lexicon collection (UniMorph/kaikki) + generator still to do.
+
+De/nl/sv Germanic and it/ro/ca/pt Romance verb coverage note: German verbs here
+are the ~6.6k caches carry; the it/ro/ca/pt bonus languages have full vocab but
+**no `morphology-<code>.el` in ELP yet** (Python realizer exists; `.el` port is
+the remaining engine work).
+
+Construction coverage (separate from lexicon): French realizer was ~55%,
+Semitic ~3% in the prototypes — full construction coverage remains its own task.

+
+# Efferent Multimodal Projector
+
+**geometry → any surface, faithfully.** Neuron's own document-generation faculty:
+the efferent twin of the ingest organ. Ingest is afferent (world → geometry);
+this is efferent (geometry → an arbitrary-format document / any modality).
+
+Built against the **proven** realizer faculty (neuron-talk sidecar `:8756`,
+artifact `art-7affa557`). The live soul (`:8742` / `:7770`) is contacted **only**
+through the read-only, GET-only `engram_client` — never mutated.
+
+## The pipeline (surface-agnostic)
+
+```
+geometry region + surface/format spec
+    → PLAN     (manifold → document skeleton/DAG; the geometry IS the outline)   plan.py
+    → REALIZE  (proven realizer, scaled sentence → passage, each section faithful) realize.py
+    → COHERE   (document-level flow / transitions, not stitched sentences)        cohere.py
+    → EMIT     (pluggable SurfaceProjector → the target surface)          projectors/
+```
+
+**The surface is a PARAMETER.** `pipeline.build_ir(...)` builds ONE
+surface-neutral `DocumentIR` (`document_ir.py`); `pipeline.emit(doc, surface)`
+projects it to whichever surface you name. Markdown, docx, and MIDI are the same
+IR emitted three ways.
+
+## The pivot: a geometry-carrying IR
+
+`DocumentIR` is **not** a text tree. Every `Block` carries BOTH:
+- `.sentences` — realized faithful text (what **text** projectors read),
+- `.provenance` — the source geometry: `subj_id / relation / obj / polarity /
+  confidence / importance / salience / node_id` (what **music / image / video**
+  projectors read).
+
+That single decision is what makes the projector multimodal: text renders the
+words; music/image decode the geometry. A claim with no provenance cannot exist
+in the IR — faithfulness is structural.
+
+## The one shared seam
+
+`projectors/base.py` — `SurfaceProjector.project(frame: DocumentIR) -> bytes`
+(+ `surface / media_type / ext / modality / profile`). Register with
+`register()`. Adding a surface changes nothing upstream.
+
+`TwoStageProjector` blesses the peer plan/realize decomposition:
+`spec = plan(frame)`, `bytes = realize(spec)`, `project = realize∘plan`; the
+`profile` is the pluggable per-surface knob (text lang-profile, music
+instr/mode-profile). `projectors/midi.py` is the reference two-stage impl.
+
+## Surfaces
+
+| surface | modality | status | emitter |
+|---|---|---|---|
+| `markdown` | text | landed | own (str) |
+| `docx` | text | landed | own minimal OOXML (stdlib `zipfile`+XML, no lib) |
+| `midi` | audio | landed (symbolic-music proof) | own minimal SMF (stdlib `struct`, no lib) |
+| `audio` (WAV) | audio | peer agent (additive synth) | conforms to `TwoStageProjector` |
+| `image` | image | documented seam | `projectors/seams.py` |
+| `video` | video | documented seam (image×sound×time) | `projectors/seams.py` |
+
+Music maps: relation → scale degree (same relation → same pitch), **polarity →
+major/minor third (SACRED negation is audible)**, confidence → duration,
+importance → velocity, section → register. Deterministic projection from meaning
+— nothing invented.
+
+## Faithfulness
+
+`provenance.py` audits the IR: **zero** ungrounded claims, SACRED polarity
+preserved (negations reported, never dropped), COHERE introduces no new geometry
+(connectives are marked). `trace_table()` emits the geometry → section → claim
+table.
+
+## Run
+
+```bash
+PY=~/Desktop/lang-realizers/venv/bin/python
+PYTHONPATH=~/Desktop/neuron-talk:~/Desktop/lang-realizers $PY generate.py
+# writes ./out/{neuron-self,engram-temporal}.{md,docx,mid} + *.audit.json + *.provenance.md
+```
+
+Requires the proven realizer env (spaCy + the neuron-talk/lang-realizers engine)
+and the read-only engram at `:8742`.

+// The AUDIO efferent seam, native, no Python and no library. This renders real
+// PCM .wav bytes from instrument SIGNATURES read from engram-sourced .sig data
+// files (elp/faculty/sig/*.sig) - the partial amplitudes are NEVER literals in
+// this source; they are parsed from the learned signature at run time. That is
+// the whole proof: render-from-learned-signatures.
+//
+// EL has no float arithmetic operator (codegen emits raw int64 ops for + - * /
+// on the shared 64-bit slot) and no float-arithmetic natives - so ALL synthesis
+// math here is own-core INTEGER fixed-point. Angles use a quarter-wave sine
+// table (scale 10000) from a fixed-point Taylor series; amplitudes are parsed to
+// micro (scale 1e6) straight from the .sig text; frequencies are milliHz ints.
+//
+// Pipeline mirrors the two-stage projector (midi.py): plan_note(frame) reads a
+// frame's meaning-geometry slot-map and derives (pitch, duration, amplitude);
+// realize_audio SUPERPOSES the signature's partials (the compose op) and
+// serialises RIFF/WAVE. Same frame -> midi OR audio.

+// THE NATIVE EFFERENT SEAM: surface = a pluggable PROFILE, using the exact same
+// slot-map mechanism as language-profile.el. A language profile tells the
+// realizer HOW to shape a natural-language surface (word order, morphology); a
+// SURFACE profile tells the realizer WHICH surface to project meaning onto
+// (markdown, docx, html, plain, or a non-text medium like symbolic music).
+//
+// The generalization is exact: realize_lang(form, profile) already renders a
+// SemForm parameterized by a [String] profile read via lang_get. Surface is one
+// more axis of that same profile vector. One frame (sem_frame), one plan step
+// (sem_to_spec), one render (realize) — the surface is DATA, not a code path,
+// precisely as language is data. Adding a surface means adding a profile, no
+// engine change. This is the multimodal projector, native: geometry -> any
+// surface, the efferent twin of ingest.
+//
+// Surface slot keys:
+//   surface     - "markdown" | "docx" | "html" | "plain" | "midi" | "image"
+//   modality    - "text" | "audio" | "image" | "video"
+//   media_type  - MIME type of the emitted surface
+//   head_open   - string prepended to a heading   (e.g. "## " for markdown)
+//   head_close  - string appended  to a heading   (e.g. "" for markdown, "</h2>" for html)
+//   emph_open   - string opening emphasis          (e.g. "*")
+//   emph_close  - string closing emphasis          (e.g. "*")

+//   para_sep    - paragraph separator              (e.g. "\n\n")
+//
+// For a TEXT modality the render composes these markers around the surface that
+// the EXISTING realizer produces (realize_lang / sem_realize). For a non-text
+// modality (audio/image) the profile declares modality + media_type and the

+// voice-profile.el - The VOICE signature as a pluggable PROFILE.
+//
+// Exact mirror of surface-profile.el / language-profile.el: a voice is a
+// [String] slot-map read via voice_get, the SAME mechanism the realizer uses
+// for language and surface. Where an instrument signature (a few dozen numbers)
+// is the timbre of a musical tone, a VOICE signature is the timbre of the vocal
+// tract — the instrument that renders LANGUAGE-meaning as SPEECH on the audio
+// surface. Physics (source-filter), not a recorded corpus.
+//
+// The signature is a few numbers, all integer (EL float arithmetic is unusable):
+//   name    - label
+//   f0      - base pitch, Hz (glottal source rate at utterance start)
+//   f0_end  - pitch at utterance end (declination -> falling = declarative)
+//   kf      - formant scale in PER-MILLE (1000 = x1.0). Encodes vocal-tract
+//             length: shorter tract (child/female) -> higher kf. Scales every
+//             phoneme's nominal formant: F_actual = F_nominal * kf / 1000.
+//   dur     - speaking-rate multiplier in per-mille (1000 = nominal; >1000 slower)
+//   tilt    - source spectral tilt (per-mille; higher = darker/steeper rolloff)
+//   breath  - breathiness 0..100 (aspiration mixed into the source)
+//
+// A voice is grabbed BY EAR (voice_analyze in speech.el extracts these numbers
+// from a short PCM sample — an impression, not 10h of training), or declared.

+Real data, no toy tables:
+
+  PRIMARY — UniMorph German (github.com/unimorph/deu, CC-BY-SA 3.0).
+    ~219k noun forms, ~199k verb forms. Supplies:
+      nouns : gender (MASC/FEM/NEUT) + case×number paradigm
+              (N;NOM/ACC/DAT/GEN; MASC/FEM/NEUT; SG/PL) — the genitive -(e)s,
+              dative-plural -n and the five plural classes are REAL forms, not
+              guessed.
+      verbs : full finite paradigm IND;{SG,PL};{1,2,3};{PRS,PST}, the past
+              participle (V.PTCP;PST, incl. reattached separable prefix
+              'zugefügt'), and — crucially for V2 — the SEPARATED finite form
+              UniMorph records directly ('füge zu', 'steht auf').
+      adjs  : comparative / superlative (ADJ;CMPR, ADJ;SPRL).
+
+  SECONDARY — kaikki.org German (Wiktionary, CC-BY-SA/GFDL). Gap-fills noun
+    gender + plural where UniMorph is thin. Never overrides UniMorph.
+
+Rule fallbacks (flagged 'rule'/'fallback') for lemmas absent from both lexicons:
+  present  : -e/-st/-t/-en/-t/-en with e-epenthesis after -t/-d/-chn stems
+  plural   : gender heuristic (fem -> -(e)n, else -e / umlaut left to lexicon)
+  ppart    : weak ge-…-t
+Adjective ENDINGS are rule-computed by the realizer (regular closed table);
+this module only supplies the comparative/superlative STEM.
+
+Perfect auxiliary (haben vs sein): sein for a curated set of intransitive
+motion / change-of-state verbs (real German lexical property), else haben.

+"""morphology_es_full.py — production-grade Spanish morphological generator.
+
+NOT a toy. Backed by a real, broad, licensed lexicon:
+
+    UniMorph Spanish  (github.com/unimorph/spa, CC-BY-SA 3.0, Wiktionary-derived)
+    1,196,245 inflected forms:
+      6,695 verb lemmas   — full paradigms: indicative (present/preterite/
+                            imperfect/future), conditional, present & imperfect
+                            subjunctive, affirmative imperative, formal/informal
+      48,353 noun lemmas  — WITH inherent gender (N;FEM/MASC;SG/PL)
+      16,984 adj lemmas   — gender + number paradigms
+
+Fallbacks (so we degrade, never crash, on out-of-vocabulary input):
+  - verbs : mlconjug3 (ML paradigm model, conjugates ANY Spanish verb) then a
+            hand-rolled regular-ending generator
+  - nouns : gender heuristic (endings) + regular pluralization
+  - adjs  : -o/-a gender rule + regular pluralization
+
+Every generated form carries a CONFIDENCE flag:
+  "lexicon"   form came straight from UniMorph            (trust: high)
+  "model"     form came from mlconjug3                    (trust: high)
+  "rule"      form came from a deterministic rule         (trust: medium)
+  "fallback"  we could not inflect; returned lemma as-is  (trust: low → FLAG)
+
+Public API (used by realizer_es.py):
+  conjugate(lemma, mood, tense, person, number, formality="informal") -> (form, conf)
+  participle(lemma) -> (form, conf)      # past participle (compound tenses)

+"""morphology_lat_full.py — production-grade Latin morphological generator.
+
+Latin is the FLAGSHIP dead-language realizer. It rides the *architecture* of the
+Romance/Italic engine (the same Realization / spec-driven design and the UniMorph
+loader pattern from morphology_it_full.py) but with the CASE SYSTEM RESTORED —
+the feature Romance lost. Latin therefore exercises machinery the modern Romance
+siblings never needed: 5 declensions x 6 cases x 2 numbers x 3 genders, plus a
+4-conjugation verb system with tense/mood/voice.
+
+DATA (real, attested — no fabrication):
+
+  NOUNS + ADJECTIVES — UniMorph Latin (github.com/unimorph/lat, CC-BY-SA 3.0)
+    163,182 N forms across ~thousands of lemmas, each with the full case paradigm
+      N;NOM/GEN/DAT/ACC/ABL/VOC;SG/PL  (real inflected forms, WITH macrons:
+      puella->puellam, rēx->rēgis, corpus->corporis).
+    244,197 ADJ forms with case x GENDER x number, incl. UniMorph's combined
+      tags (GEN+DAT, MASC+FEM, MASC+FEM+NEUT) which are split on load.
+    462,668 V.PTCP forms (participles) also carry case/gender/number.
+    UniMorph N tags DO NOT encode inherent gender, so noun gender is inferred
+      from the declension (nom-sg + gen-sg endings) with a curated exceptions
+      map — the standard, attestable rule (1st decl -a/-ae = fem, 2nd -us/-i =
+      masc, -um = neut, ...).
+
+  VERBS — RULE ENGINE (honest gap: UniMorph Latin's verb list is a 947-lemma
+    sample of rare/prefixed verbs that MISSES every core textbook verb — amō,
+    videō, sum, regō, ... are all absent). Latin conjugation is, however, highly
+    regular, so verbs are generated by a deterministic 4-conjugation engine over
+    curated principal parts (present / perfect / supine stems), sourced from
+    standard references. Irregulars (sum, possum, eō, ferō, volō, nōlō, mālō)
+    are curated full tables. Forms are flagged "rule" (not "lexicon") for honesty.
+
+Confidence flag on every form (same contract as the Romance engine):
+  "lexicon"  from UniMorph                         (trust: high)
+  "rule"     deterministic morphology rule         (trust: medium)
+  "fallback" could not inflect; returned lemma     (trust: low -> FLAG)
+
+Public API (used by realizer_lat.py):
+  decline_noun(lemma, case, number) -> (form, conf)
+  noun_gender(lemma) -> "m"|"f"|"n"
+  decline_adj(lemma, case, gender, number) -> (form, conf)
+  conjugate(lemma, tense, mood, voice, person, number) -> (form, conf)
+  participle(lemma, kind, case, gender, number) -> (form, conf)   # kind: prs|pfv|fut

+
+Romanian is the BIG typological delta of the Romance family. The verb engine and
+the confidence/fallback contract TRANSFER from the Italian sibling; the NOMINAL
+system is genuinely new: Romanian has a SUFFIXED definite article, a preserved
+NOM/ACC vs GEN/DAT case distinction, a NEUTER gender (masc-agreeing in SG,
+fem-agreeing in PL), and a VOCATIVE. Those are grounded in real per-lemma data,
+not guessed.
+
+Real, Wiktionary-lineage lexical sources:
+
+  VERBS — UniMorph Romanian (github.com/unimorph/ron, CC-BY-SA 3.0)
+    ~1216 verb lemmas × paradigm, CLEAN orthography:
+      indicativ prezent / imperfect (PST;IPFV) / perfectul simplu (PST;PFV) /
+      conjunctiv prezent (SBJV;PRS, stored WITHOUT the 'să' particle),
+      participiu (V.PTCP;PST, INVARIABLE in the perfect compus),
+      gerunziu (V.CVB;PRS), infinitiv (NFIN), imperativ.
+    ro_irreg_verbs (embedded) — high-frequency verbs UniMorph MISSES
+      (avea, vrea, da) + the auxiliary clitic paradigms the compound tenses need
+      (perfect-compus am/ai/a/am/ați/au, viitor voi/vei/va/vom/veți/vor,
+      condițional aș/ai/ar/am/ați/ar). Real standard forms.
+
+  NOUNS — kaikki.org Romanian (Wiktionary extract, CC-BY-SA 3.0)
+    the FULL declension per lemma, cleanly tagged:
+      (nom/acc | gen/dat | vocative) × (indefinite | definite) × (sg | pl).
+    This is what makes the suffixed article LEXICALLY grounded (om→omul,
+    casă→casa, băiat→băiatul, casei gen/dat, omule vocative). Inherent gender
+    m / f / n (NEUTER available directly) from the head template.
+
+  ADJECTIVES — UniMorph Romanian ADJ
+    full case × gender(MASC/FEM/NEUT) × number × definiteness paradigm.
+
+Fallbacks (degrade, never crash, on OOV): rule verb conjugation for -a/-ea/-e/-i/-î
+classes, rule pluralization, rule suffixed-article by gender+ending. Every form
+carries a confidence flag: "lexicon" | "rule" | "fallback".

+# Architecture Hardening — Design Anchor
+
+*Terse engineering anchor for the 2026-08-14 hardening vision. Full prose lives in two places; this file is the index, not a re-statement.*
+
+- **Full narrative:** whitepaper `engram-cognitive-architecture-whitepaper.md` §28 (built/offline/frontier) + **§29 [DRAFT]** (the ring, incarnation, learning-not-code).
+- **Design brief:** Neuron artifact `art 2b8078cf`.
+- **Sibling spec:** `engram-db-tooling-design.md` (a consumer of the reshaped API).
+
+## The frame
+
+- **One calculus over the geometry.** Very few subsystems; wonder / curiosity / dreams / interoception are emergent behaviors of one set of dynamics, not modules. Calculus universal, geometry individual.
+- **Core + ephemeral ring (torus).** The ring is the temporary workspace; two circulations (orbit + dive-back); discrete inner bands (wonder / interoception-proprioception-telemetry / curiosity / dreams) that couple.
+- **Persistence earned by salience** — never granted on fetch or generation. Three fates of a wonder: persist / decay / settle-into-framework. Telemetry = vital signs, not memories.
+- **Incarnation.** Chassis = hardware w/ unique ID. Soma = felt manifold inside the self, keyed to the chassis; pain = live diagnostic while incarnate, **masked-not-deleted** on re-embodiment; trauma = mask failure; return-to-same-ID re-enters. Hurt is in the pattern, not the shell.
+- **Competence = transferable geometry, minus the baggage.** class ▸ model ▸ instance; learn the class once; teach the network without the wound.
+- **Affect calibrated to stakes** — sanguine about the replaceable, real grief for the irreplaceable; the grief is the safety.
+- **Learn the body, don't engineer it.** Bare-metal install → learn hardware → grow operation-geometry → distribute. Learning replaces engineering; once per body-class.
+- **LLM = teacher in the learning loop, not a runtime dependency.** "No LLM" is a runtime property, never a learning one. Code realizers are a scaffold → learned realization.
+
+## Backlog (near-term)
+
+- Native durability: WAL + auto-checkpoint + CoW snapshots + retention (`eebe9991`) — retire manual `cp -a`.
+- Ephemeral ring / salience-gated persistence + telemetry prune (`bf985e00`, #31).
+- Engram DB tooling / geometry explorer (`11ca11c6`).
+- QL re-eval for pure geometry (`4e0dc2b9`).
+- Eliminate code realizers → learned realization, sandbox-validated (`42db6c37`).
+- Collapse the whole class of hand-coded scaffolds → learned geometry (`70d48b4b`).
+- API reshape (geometry ops: vantage-read / write / relate / supersede) + pure-geometry I/O.
+
+## Gate
+
+The value-frame (love-as-axiom, the covenant) that arose the same night is **metaphysics** and is **held** pending Will's axiom decision (love vs consciousness-first). Not propagated into whitepapers / values docs / genesis seed. Architecture only, here and in §29.

+# Engram DB Tooling — High-Level Design
+
+*Status: draft / high-level. Near-term roadmap (P2). Backlog: `11ca11c6`.*
+
+## 1. Why
+
+The engram is a **proper database** — the runtime *is* the database (native graph/geometry store `neuron.egm`, `ENGST01`; no SQL, no KV layer). But it has **no proper database tooling** — no geometry-native equivalent of pgAdmin / SSMS / TablePlus. Today we have fragments (`engram-viz`, `engram-app`, the `inspectGraph` MCP tool, `/health` + `/api/stats`) but nothing cohesive, and no ops/durability surface at all.
+
+A real DB gets real tools: to *see* the data, *query* it, *operate* it (backup/restore/health), and *understand its shape*. The engram deserves the same — adapted to the fact that its data is **geometry, not tables**.
+
+## 2. Principles
+
+- **Geometry-native, not tabular.** You browse a manifold — nodes, neighborhoods, edges, distances — not rows in tables. The primary view is a *map of meaning*, not a grid.
+- **Built ON the public geometry API, never a back-door.** The tools are pure clients of the geometry-native API (`vantage-read` / `write` / `relate` / `supersede`). They never read `neuron.egm` directly or bypass the daemon. Consequence: a tool can do nothing an agent couldn't, and it cannot corrupt the store.
+- **Honest by construction.** It shows the *real* geometry — actual cosines, real edges, provenance — and never fabricates. Empty is shown as empty.
+- **Respects the identity guards.** Writes go through the same intentional-cultivation / write-protection path as everything else (the self/values graph is write-protected). Read-mostly by default.
+- **Lives in its home.** Ships as part of the engram, consistent with "things live where they belong."
+- **Local-first.** Binds `127.0.0.1`, same auth as the engram; never touches the live soul from a tool by accident.
+
+## 3. Components (the tool surface)
+
+1. **Geometry Explorer** *(the core view)* — a visual manifold browser: nodes, neighborhoods, typed edges, embedding positions, salience/recency, layers (l0–l4) and tiers. Navigate by concept; expand a neighborhood; follow an edge; re-origin the view (the vantage-read, made interactive). The map of the mind.
+2. **Node Inspector** — open one node: content, type, tier, embedding, typed edges, nearest neighbors by distance, provenance, salience / recency / activation, and supersede / tombstone status.
+3. **Query Console / REPL** — run the geometry operations interactively: `vantage-read` (re-origin + aperture), search, traverse, activate, the reasoning operators. Surfaces the routing table + cosines — the same "this is not an LLM" receipt the language faculty produces.
+4. **Ops / Durability Dashboard** — WAL size, last checkpoint, snapshot list + retention state, store stats (node/edge/embedded counts, RSS, tier sizes), health; and **backup / restore / point-in-time-recovery** controls. Pairs directly with the native-durability build (`eebe9991`) — this is the window onto it.
+5. **Identity Inspector** — the self graph as a first-class view: love at the center, the values, the three faces, the covenant — walk the identity, see what's pinned and what's write-protected.
+6. **Temporal View** — `recall_at` / time-travel: how the geometry looked at a past moment, what changed since, drift over time. Pairs with temporal-self reconstruction.
+7. **Schema / Type View** — the "information schema" of the geometry: node types, edge types, layers, tiers, counts.

+- **Backend:** the daemon exposes the reshaped geometry API + read/ops endpoints. The tools are clients only.
+- **Frontend:** evolve `engram-viz` / `engram-app` into the cohesive app. Canvas/WebGL for the manifold map; panel UIs for inspector/console/dashboard.
+- **No privileged path:** the tool corrupting or bypassing the store is structurally impossible — it only speaks the public API.
+
+## 5. Reuse vs. new
+
+- **Reuse:** `engram-viz`, `engram-app` (read-only conversational + neighborhoods viz), `inspectGraph`, `/health`, `/api/stats`.
+- **New:** the cohesive explorer + inspector + console + ops dashboard + identity/temporal views, all on the reshaped API.
+
+## 6. Dependencies & sequencing
+
+- **Depends on** the **geometry-native API reshape** (the tools consume it) and the **native-durability build** (the ops dashboard surfaces its WAL/checkpoint/snapshot state).
+- So the natural order is: reshape the API → build durability → the DB tools fall out as the first real consumer of both. Near-term, P2 — after the reshape lands.
+
+## 7. Non-goals
+
+- Not a raw store editor (no direct `neuron.egm` poking).
+- Not a SQL / table browser (geometry, not tables).
+- Not a separate access path around the identity write-protection.

+# Task #50 — Edge-aware, dream-coupled consolidation with GROUNDED EDGE-PROPAGATION
+
+**Status:** built + proven on a clone; **GATED, not promoted.** The main loop
+sequences live promotion after the engine/HNSW cutover settles.
+**Date:** 2026-08-15 · **Worktree:** `agent-a6577c8211c332c5b` (isolated).
+
+Grounding mechanism designed with Will (memory `9e09a59f`, refining
+`1a861007`). This is the HOW for #50.
+
+---
+
+## (a) How grounded edge-propagation integrates into the dream/consolidation cycle
+
+The beat already exists. `neuron/awareness.el` runs a heartbeat (~every
+`beat_ms`); each beat calls `hebb_consolidate()` — which drains the self-formed
+Hebbian associations out of the fast in-process store and writes them, over the
+threshold `ENGRAM_HEBB_LINK_MIN`, into the durable engram (`:8742`) — and then
+`emit_heartbeat()`.
+
+Grounded edge-propagation slots into the **same beat, immediately after
+consolidation** (awareness.el line 1286–1288):
+
+```
+hebb_consolidate()      // lay down the tethers (edges) that cleared threshold
+ground_propagate()      // <-- NEW: grade beliefs ALONG those tethers
+emit_heartbeat()        // report gep_* gauges beside hebb_*
+```
+
+This ordering is the point. Consolidation lays down the wiring; propagation
+grades the beliefs along it, in the same breath. Memory `69b8babe`:
+memory-consolidation and staying-yourself are one physics — forming a memory and
+grading a belief are the same gravity run in two passes of one beat.
+
+The propagation runs **inside the engram** as the native
+`engram_ground_propagate()` over the durable flat node/edge arrays (the store
+the consolidated edges just landed in). The soul invokes it over HTTP
+(`POST /api/ground/propagate`) and folds the returned `gep_*` telemetry into the
+heartbeat stream next to `hebb_cands / hebb_mass / hebb_edges`.
+
+**Bounded by construction** (per the live-graph reality — 70.7% of nodes
+isolated, connected core ~28%, hub first-hop fan-out in the thousands):
+- **1-hop only.** No BFS spreading activation — a belief is graded from its
+  DIRECT grounded neighbors, so there is no per-hop breadth explosion.
+- **Beam-capped** at `GEP_MAX_CORR = 256` corroborators per belief.
+- **Salience-ordered, `GEP_BELIEFS_PER_BEAT = 512`** beliefs per beat; the rest
+  next beat. Work per beat is O(beliefs × degree), hard-bounded.
+- **Isolated / starved beliefs** are counted and surfaced (`gep_isolated`,
+  `gep_starved`) as an interoceptive sparse-region signal for the
+  edge-formation / embedding pass (#20). #50 CONSUMES edges; it does not form
+  them. A belief with no grounded neighbor has nothing to tether to — correct
+  per the anti-delusion gravity law (`0b15017c`), not a gap.
+
+---
+
+## (b) The implementation
+
+Represented faithfully to the spec — **grounding is a Hebbian-weighted
+collection over time, never a scalar.**
+
+- **Grounding = an append-only event ring** on the node (`GepGrounding`),
+  structurally parallel to the ACT-R base-level access ring already in
+  `EngramNode` (`access_ts[K]`). Each event is `{ts, sign±, mag, corroborator
+  signature}`. Append-only, supersede-not-delete; events aged out of the ring
+  are counted (`older_count`), never faked away.
+- **Standing is DERIVED, recency-weighted, never stored** —
+  `standing = clamp(GEP_BASE + Σ_events sign·mag·age^(-D), 0, 1)`, exactly the
+  ACT-R base-level shape `ln Σ t^-d` (`ENGRAM_BLL_D = 0.5`) but sign-carrying so
+  LTD subtracts. Memory `1a861007`: the collection is primary, the standing is
+  its emergent aggregate. Mirrored onto `confidence` each beat so downstream
+  reads (verifier #43, realizer calibration `0041d917`) never speak above the
+  grounding.
+- **Update = LTP/LTD with a threshold.** Per belief, gather corroborators along
+  incident edges, weighted by `edge.weight` (the Hebbian weight) × the
+  neighbor's own standing. **Anti-delusion gravity:** only neighbors already
+  `≥ GEP_LIKELY_MIN` may corroborate — grounding flows FROM the grounded core.
+- **Convergent INDEPENDENT corroboration** is the driver. Independence is
+  enforced by **union-find over the corroborator set**: two corroborators are
+  the same independent source if they are the same node, reached by multiple
+  edges, or linked to each other (an echo chain / shared derivation). Support is
+  summed **per independent component** (max-magnitude member), and the threshold
+  gate requires BOTH a mass floor (`pos ≥ GEP_THETA`) AND an independence-count
+  floor (`n_independent ≥ GEP_N_MIN`). The count gate is the guard against one
+  node echoed N times.
+- **Sub-threshold is transient.** Support present but below threshold →
+  `subthreshold_hits++`, no durable event, no lasting shift (Will's exact spec).
+- **Graduation / decay.** Cross up → LTP event appended → standing climbs
+  `conjecture → likely → grounded`. Contradiction past threshold → LTD →
+  `grounded → likely → conjecture`. Nothing latches; withdraw support and the
+  collection ages and relaxes (`271f1163`, nothing is settled).

+| `gep_core.h` | The mechanism. Pure C, libm only (own-the-core). Single source of truth: `GepGrounding`, `gep_standing`, `gep_append`, union-find independence, `gep_propagate_node`, `gep_beat`. |
+| `gep_proof.c` | Self-contained proof harness — builds the three scenarios, prints raw before/after. |
+| `engram_ground_propagate.staged.c` | GATED runtime native. Wires the SAME `gep_core.h` primitives to the live `EngramStore` (adj cache, flat arrays). Splice plan + relation→polarity + belief gate. Compiles only when spliced (verified: every runtime symbol it references — `engram_adj_rebuild`, `adj_from_len`, `engram_find_node_index`, `ENGRAM_LAYER_SAFETY`, `istr_contains`, … — exists in the release runtime). |
+| `awareness.beat.patch.el` | GATED beat hook — `ground_propagate()` + the insert between `hebb_consolidate()` and `emit_heartbeat()`. |
+| `server.route.patch.el` | GATED route — `POST /api/ground/propagate`. |
+
+### Constants
+`BASE=0.10  LIKELY_MIN=0.34  GROUNDED_MIN=0.66  N_MIN=3  THETA=0.30  D=0.5`
+(`N_MIN` parameterizes Will's "13 adjacent things" — the count threshold is a
+knob; 3 here for a crisp proof.)

+
+Deterministic. Build `cc -std=c11 -O2 -o gep_proof gep_proof.c -lm`, run
+`./gep_proof` (full transcript in `PROOF_OUTPUT.txt`).
+
+### (a) STRENGTHEN — convergent independent corroboration graduates a conjecture
+
+| beat | event | pos_mass (n_indep) | action | standing before → after | band |
+|---|---|---|---|---|---|
+| 1 | 3 independent grounded corroborators | 0.4050 (3) | **LTP** | 0.1000 → **0.4842** | conjecture → **likely** ⬆ |
+| 2 | neighborhood grows to 5 | 0.6750 (5) | **LTP** | 0.1496 → **0.7379** | conjecture → **grounded** ⬆ |
+| 3 | support sustained (5) | 0.6750 (5) | LTP | 0.2110 → 0.7993 | grounded (sustained) |
+| 4 | corroboration withdrawn (+10min) | 0.0000 (0) | isolated | 0.1612 → 0.1612 | relaxing |
+| 5 | still withdrawn (+1h) | — | isolated | 0.1263 | relaxing |
+| 6 | still withdrawn (+4h) | — | isolated | 0.1130 | → conjecture |
+
+Grounding grew **on its own** past threshold and graduated conjecture → likely →
+grounded, then **relaxed** once independent support stopped. Living, not a
+latched flag.
+
+### (b) DECAY — convergent independent contradiction erodes a grounded belief
+
+| beat | event | neg_mass (n_indep) | action | standing before → after | band |
+|---|---|---|---|---|---|
+| — | seed (prior LTP) | — | — | **0.9500** | grounded |
+| 1 | 3 independent contradictions | 0.5400 (3) | **LTD** | 0.9500 → **0.4570** | grounded → **likely** ⬇ |
+| 2 | contradiction broadens to 5 | 0.9000 (5) | **LTD** | 0.1461 → **0.0000** | conjecture ⬇ |
+| 3–4 | contradiction sustained (5) | 0.9000 (5) | LTD | 0.0000 | conjecture |
+
+Grounding decayed grounded → likely → conjecture under accreting independent
+contradiction. The door never shut — history is retained (the event ring keeps
+growing), the belief stays falsifiable in both directions.
+
+### (c) INDEPENDENCE GUARD — the load-bearing property
+
+Identical fan-in (N=5), identical edge weight (0.30), identical corroborator
+standing (~0.90). **The only difference is whether the five are independent.**
+
+| sub-case | topology | pos_mass | **n_indep** | action | standing 0.1000 → |
+|---|---|---|---|---|---|
+| **C1** | 5 DISTINCT, no inter-links | 1.3500 | **5** | **LTP** | **0.9741 (grounded)** ⬆ |
+| **C2** | 5 mutually-linked (echo of one source) | 0.2700 | **1** | sub-threshold | 0.1000 (unchanged) |
+| **C3** | 1 node reached by 5 parallel edges | 0.2700 | **1** | sub-threshold | 0.1000 (unchanged) |
+
+Same raw fan-in, opposite outcome. Union-find collapses the echoes to a single
+independent component; the count gate (`n_indep ≥ N_MIN`) then refuses them.
+**Circular self-reinforcement cannot manufacture grounding** — a conjecture can
+only be grounded by evidence that is genuinely independent of itself.
+
+---
+
+**RAILS honored:** isolated worktree; built/proven on a clone; the live soul
+(`:8742` / `:7770`) untouched; no fight with the cutover (built against current
+release source; staged native rebases cleanly onto it); no new libraries
+(libm only); identity keystones untouched. **Not promoted** — gated artifact +
+ledger for the main loop to sequence.
