/* bench_discrimination.c — M9 REFINEMENT bench: measures whether mean-centering
* the anisotropic nomic-embed-text space sharpens the §5 geometry operators on
* REAL data. Read-only over a COPY of the live store (never the live file).
*
* usage: bench_discrimination [store.egm]
* (or set ENGRAM_BENCH_STORE). If no store is given/openable it prints
* SKIP and exits 0 — so it is safe in CI without live data.
*
* It picks two semantically distinct cohorts by keyword (domain A vs domain B),
* computes the global mean over the embed-eligible set (via engram_geo_mean_build
* — the same offset the descriptor uses), then reports BEFORE (raw unit space)
* vs AFTER (mean-centered space):
* - cross-centroid cosine (lower = better separated)
* - cross-centroid Euclid dist (translation-invariant: a control)
* - intra-cohesion per domain (member cos to own centroid)
* - overlap operator (cross_cos / sqrt(intraA*intraB): ~1 = domains
* indistinguishable, ~0 = cleanly separated)
* - angular separation ratio z (centroid angle / summed angular spread)
* - mean pairwise cosine sample (the anisotropy headline; ~0.55 raw -> ~0 ctr)
*
* Pure C11; links engram_store.c + engram_geometry.c; -lm.

/* test_compaction.c — M5 gate: ONLINE COMPACTION + background checkpointer.
*
* Pure C. Build: gcc -O2 test_compaction.c ../../lang/runtime/engram_store.c -o t
* Writes ONLY under a throwaway /tmp dir. Never touches ~/.neuron or live ports.
*
* Proves:
* 1) RECLAIM — tombstone/forget a large fraction of nodes + re-put many edges
* (dead versions) + orphan large-record overflow chains, then compact:
* page count AND file size drop, yet EVERY live record survives bit-exact and
* the id + adjacency indexes resolve correctly at the relocated positions.
* 2) CRASH-DURING-COMPACTION — kill at phases 0/1/2; recovery is always a
* consistent store (crc clean, every live record intact), never corrupt.
* 3) BACKGROUND CHECKPOINTER — a low ops / WAL-bytes threshold fires a checkpoint
* automatically on the write path; the WAL prefix is reclaimed; recovery works.
* 4) POOL COOPERATION — compaction under a tiny ENGRAM_POOL_FRAMES stays correct
* with no stale frame surviving for a relocated page.

* runs; this measures the EXISTING EWMA accrual.
* connect — flag ON. Seed, activate to populate WM, then create a STRONG ISE
* (connects to wm_top) and a WEAK ISE (below the bar → nothing).
* Exports the graph so edges from each ISE can be counted.
* perm — flag ON. Load two OLD InternalStateEvent nodes; promote one to
* permanence; prune telemetry; export so the durable one is shown
* to survive while the ephemeral one is swept.
* offcheck — flag OFF. Prove creating an ISE forms NO edges and

## Current work in this worktree — the API reshape / decorated seam (IN PROGRESS, 2026-08-14)
This is the `api-reshape` worktree. The build here reshapes Neuron's external
surface and how it is *declared* — proven on isolated dev-port clones only; **live
prod engram `:8742` is untouched and nothing is promoted.** Full framing lives in
`neuron/docs/architecture/06-cognitive-architecture.md` (Update — 2026-08-14 deep
night) and `02-components.md §5`.
- **Surface collapse.** The ~90 noun-organized CRUD MCP tools collapse to a few
**geometry ops** — `read` (the *vantage-read*: re-origin + salience/recency +
an **aperture** → a bounded slice, curing the whole-self dump), `write`,
`relate`, `supersede` (evolve/tombstone/promote, never a hard delete) — plus the
agentic primitives `think`/`attend`/`learn`/`ground`/`assert`. The old noun is a
`type` parameter. Implemented in `tools/api-reshape/surface.el` with a parity
harness (`parity.sh`); aperture proven to bound output. **Not yet:** compiled
into the MCP server, hot-swap, all-alias dispatch.
- **Decorated seam.** `@route(path,method,…)` makes codegen synthesize
`el_route_dispatch` (replacing the hand-written `handle_request` if-else) —
proven decorate→serve on `:8951`. `@manager`/`@engine`/`@accessor` are **parsed
but structurally inert** in the shipped compiler today; the `@route` codegen
lives on the **unmerged branch `feat/el-route-decorators`**. Telemetry-emit and
dharma-bus auto-wiring at the boundary are **staged, not shipped**. In-process,
an `@accessor` reaches the engram via **`engram_*` builtins**, not `http_get`.
**Do not edit** the protected build sources while this is in flight:
`el-compiler/src/codegen.el`, `el-compiler/runtime/el_seed.c` (and the archived
`legacy/el_runtime.c`), the `runtime/engram_*.c` boot files, and `surface.el`
(when present in the reshape tree) — these are owned by the build agents.

## What El Is
El compiles `.el` source → C → native binary. Every El value is `el_val_t` (int64_t). Strings are heap pointers cast through int64_t. The compiler is written in El (self-hosting).

/* engram_cognition.h — THE ONE OPERATION.
*
* The buildable form of the "cognition is one operation" theory (design doc
* engram/spec/cognitive-architecture.design.md; memory bdc8a488 / d582a766).
*
* Cognition is ONE operation — think — a directed traversal-READ of the geometry
* from an anchor, steered by a learned STANCE, whose output is a GRADIENT (a
* direction + spread over the geometry), never a point. The named faculties
* (reason / induce / abduce / analogy / relate / plan / ground) are human LABELS
* on regions of think's steering space: each faculty == { think + a named stance }.
* Collapse-to-a-point happens only at EXPRESSION (a separate faculty), never in think.
*
* NAMING (Will's directive): the surface verbs name the cognitive ACT being
* performed (think / reason / induce / ground / verify), not the internal function
* shape. The single frozen primitive underneath every faculty is engram_think,
* which composes over engram_reason_point_fit + the §5 geo-algebra. Those never
* learn. Only the STANCE learns.
*
* "Stance" is the theory's steering PRIOR, deliberately named distinctly: in this
* codebase the token "prior" already means previous-VERSION (supersession). A
* Stance is a learnable bias/disposition over the geometry — which axes matter,
* which way pays off, plus a calibrated track record — attached to a faculty-label
* and a region, and grounded-for-whom.
*
* PURE + (mostly) READ-ONLY, stdlib + libm only. think() and the warp are pure
* over their inputs. Persistence (Stance <-> StoreNode, grounded-by edges) is the
* only part that touches the store, and it is additive / supersede / tombstone —
* never mutate-in-place, never delete. It NEVER touches the live daemon: all
* offline against a scratch store, per the design's rails.

* FRAME CONTRACT: both inputs MUST have been built in the SAME frame — identical
* emb `dim` and identical `global_mean` (centered against the one true store-wide
* mean). The reify path builds every neighborhood that way, so descriptors are

* covariance Σ = Σ_k extent_k² · a_k a_kᵀ over its retained principal axes
* (top_axes; the discarded tail variance is not modeled). Every operator mirrors

* (proxy works in a 24-dim global-PCA reduced dense frame; C in full-dim low-rank).

* neighborhood so priming centers against the SAME true mean.
* - "Neighborhood" : one reified neighborhood. emb = the RAW centroid (prototype
* point, so it stays centroid-ANN-able; centered_centroid =
* emb - meanframe). metadata = the compact "GEO1" schema:
* hub id, meanframe ref, scalar shape (radius, total_variance,
* k_core, co_registration, n_embedded), axis EXTENTS (ellipsoid
* half-widths), and the MEMBER list {id -> membership, centrality,

* DIRECTION vectors are not persisted (extents capture the ellipsoid scale; the

/* engram_verify.h — the VERIFIER layer: GROUNDING + CONSISTENCY over the live
* geometry (engram_geometry.h) and reasoning (engram_reason.h) operators.
*
* The geometry PROPOSES (cheap, creative, sometimes wrong); the verifier DISPOSES.
* This layer catches the class of failure a grammar check never sees: a fluent,
* confident, WRONG output — the "plausible lie". The motivating case: a translation
* that DELETED a negation so "you never fought" became "you argued" — reassurance
* inverted into accusation, grammatical and invisible, catchable ONLY by the geometry.
*
* GROUNDING claim → is there ANY real structure that supports it, or is it
* floating free of the manifold? (anti-hallucination gate)
* CONSISTENCY claim → does it CONTRADICT the established structure? Two catches:
* (a) POLARITY: the claim lands on the OPPOSITE side of a negation
* axis from the grounded truth (the reassurance→accusation catch),
* (b) GEOMETRIC: the claim sits inside a region it must be far from,
* or violates a max-distance constraint to its context.
*
* PURE + READ-ONLY (stdlib + libm only): every function consumes a claim POINT
* (float* in R^dim) plus GeoDescriptor(s), and NEVER touches the store, index, or
* activation. All geometry is delegated to engram_reason_point_fit / engram_geo_*;
* this file only composes and applies thresholds.
*
* FRAME CONTRACT (inherited): the claim point and every descriptor passed together
* MUST share emb `dim` and the same `global_mean` frame — exactly the §5 operator
* contract. A function returns <0 on a dim/frame mismatch or bad argument.

*
* Algorithm: Malkov & Yashunin, "Efficient and robust approximate nearest

* - multi-layer graph; level ~ Exp(1/ln M), assigned by a per-node seeded PRNG
* (deterministic: seed = FIXED_SEED ^ node_ordinal) so a rebuild is bit-for-
* bit reproducible regardless of wall-clock or global rand() state.
* - greedy descent through upper layers to an entry point, then an ef-bounded
* best-first search at each layer (Algorithm 2).
* - neighbour selection by the diversity heuristic (Algorithm 4), not plain
* k-nearest, with keep-pruned backfill for connectivity.
* - bidirectional links; a neighbour whose degree exceeds M (2M on layer 0) is
* re-pruned with the same heuristic.
*
* Metric: vectors are L2-normalised on entry, so cosine similarity == dot

# Neuron API-surface reshape
Design: artifact **0e828907** + design-brief **2b8078cf §5**. Collapse ~90
functional-CRUD MCP tools into a handful of **geometry ops** over the one
geometry, plus the **live agentic primitives** already in the engram cognition
build. **Type is a parameter, not a tool-per-noun.**
Ground-truth: routes verified against the live cognition binary
`engram.cognition-20260814-160045` (route source: branch
`feat/cognitive-architecture`, `engram/src/server.el`). Built + validated on an
**isolated nsbx clone** (`:8900`); live `:8742` untouched.
**The decoration IS the API.** `surface.el` is El-native: each op is one function
decorated with its `@route` (codegen synthesizes `el_route_dispatch` — no
hand-written 90-branch dispatch) and its VBD role (`@accessor` = engram I/O,
`@manager` = agentic orchestration + DHARMA emitter). Handlers call the engram
**in-process** via `engram_*` builtins (not `http_get` — that idiom only existed
because the old MCP wrapper was a separate process). Decorate→serve is **proven**:
`route_proof.el` serves decorated handlers on :8951; `surface.el` compiles and the
dispatcher is generated for all 8 ops. See `SEAM_STAGED.md` for the three-part seam
(route / telemetry+interoception / bus) ground-truth and the staged boundary diff.
**Clone boot recipe (gate-1):** cold-boot from `neuron.egm` with the WAL set aside
(the live-store clone's WAL is torn and loops on replay) + `ENGRAM_WAL=on` (routes
node-writes to the WAL-append path; without it `persist_node`→full-store checkpoint
**segfaults** a clone) + `ENGRAM_GEOMETRY_PRIMING=1`. **Anchors must be node-ids**
(think/ground/learn resolve each seed via `engram_find_node_index`; free text →
"geometry unavailable"). With this recipe the **full op set is proven live on the
clone** (below).
## Layer 1 — geometry ops
| op | signature | engram route | replaces (~) |
|----|-----------|--------------|--------------|
| `read` (vantage-read) | `read({vantage, type?, aperture:{k,depth}})` | GET `/api/search` \| `/api/neighbors/<id>` \| `/api/nodes/<id>` \| `/api/activate` | inspectGraph, searchGraph, traverseGraph, searchKnowledge, browseKnowledge, retrieveKnowledge, inspectMemories, searchEntities, recall, compileCtx, getSelfModel, reviewBacklog, findArtifacts, browseProcesses, listWork, inspectConfig … (~30) |
| `write` | `write({content, type, tags, importance})` | POST `/api/nodes` | remember, captureKnowledge, draftArtifact, planWork, defineProcess, addWonderQuestion, logInternalStateEvent … (~15) |
| `relate` | `relate({from, to, relationship, weight?})` | POST `/api/edges` | linkEntities, linkCausal, restructureCausalGraph, pin |
| `supersede` | `supersede({id, action: evolve\|supersede\|tombstone\|promote, content?})` | write+relate(`supersedes`) / DELETE `/api/nodes/<id>` (immutable marker) | evolveMemory, evolveKnowledge, forget→tombstone, promoteKnowledge, reviseArtifact, trackWork, progressWork(update) … (~15) |
**Vantage-read = the whole-self-dump fix.** Re-origin at a point + salience +
recency + **aperture** → a *bounded* slice. Aperture (`k`/`depth`) caps output:
measured on the clone, `limit=3 → 15 KB` vs `limit=50 → 363 KB`. The old path
returned 60k–230k-char unbounded traversals (this very session hit 104 KB and
409 KB live).
## Layer 2 — primitive agentic tools (Neuron runs itself)
The base verbs all agentic behavior composes from — grounded in the LIVE
cog-arch (`think` is the one operation; faculties are its steering-space labels;
the correspondence-beat is the reflexive learning loop).
| op | signature | engram builtin | status on clone (gate-1 recipe) |
|----|-----------|----------------|---------------------------------|
| `think` | `think({seeds, faculty})` faculty ∈ reason·abduce·induce·plan·analogize·recognize·discern·synthesize | `engram_think_json` | **PROVEN** — all 8 faculties return real 768-dim gradients (n_support 30–282) |
| `attend` | `attend({node, observer, salience})` | `engram_attend_json` | **PROVEN** (returns `salient-to`) |
| `assert` | `assert({claim, for_whom, floor})` — realize, honesty-floored | `engram_assert_json` | **PROVEN** |
| `ground` | `ground({claim, evidence, for_whom})` node-id anchors | `engram_ground_json` | **PROVEN** (grounded-by edge, grounding=0.912, written) |
| `learn` | `learn({seeds, faculty, keystone})` — the correspondence-beat | `engram_correspondence_beat_json` | **PROVEN** (real Stance: `stance-induce-…`, brier, reliability, written) |
`comprehend`/`realize`/`intend` are **compositions**, not separate live
primitives: comprehend = write+activate (world→geometry), realize = assert
pointed at the world (geometry→act), intend = attend at a goal-region. The
skill-learning loop (decompose→detect-gap→reach-out-on-sparsity→verify-by-
execution→integrate) composes over `think`+`ground`+`learn`+`write`/`relate`.
## Identity is write-protected
`write(type=self|values)`, and `relate`/`supersede` touching the keystones
`kn-efeb4a5b…` / `kn-5b606390…`, are refused — identity routes through
intentional-cultivation, as enforced today.
## How the caller invokes Neuron agentically
Once the ops are registered as MCP tools (aliases in `surface.el`), the caller
(Claude, this loop) calls e.g.:
```
neuron.think({ seeds: "kn-efeb4a5b…", faculty: "plan" }) # Neuron reasons over its own geometry
neuron.attend({ node: <region> }) # aim its attention
neuron.learn({ seeds: <region>, faculty: "induce" }) # calibrate its own prior (correspondence-beat)
neuron.read({ vantage: "self", aperture:{k:12} }) # bounded self-slice (no dump)
```
and **Neuron does the agentic work over its own geometry** — the beginning of it
running itself.
## Files
- `surface.el` — the reshaped surface as **decorated El-native components** (`@route` + `@accessor`/`@manager`, in-process `engram_*` builtins). Compiles; dispatcher generated for all 8 ops.
- `route_proof.el` — a standalone decorated El service that **proves decorate→serve** on :8951 (built with the worktree-rebuilt `elc-route`).
- `SEAM_STAGED.md` — the three-part seam (route / telemetry+interoception / bus) ground-truth + the exact staged `cg_fn` diff for boundary auto-emit.
- `agentic_loop.el` — the four-call loop (think→attend→learn→read) as compilable El.
- `parity.sh` — API-level parity harness against the clone.
## Honest ledger (built vs staged)
- **Route seam — IMPLEMENTED + PROVEN:** ported the `@route` codegen (from `feat/el-route-decorators`) into the worktree, rebuilt `elc` self-host, proved decorate→serve (`route_proof.el` on :8951); `surface.el` compiles with `el_route_dispatch` generated for all 8 ops.
- **All ops PROVEN live on the clone** (gate-1 boot recipe, node-id anchors): read, write, relate, supersede (immutable), tombstone, think (8 faculties), ground, attend, learn — daemon alive through all mutations (node_count 13173→13176).
- **Aperture-boundedness PROVEN:** vantage-read `limit=3 → 15 KB` vs `limit=50 → 363 KB` (fixes the whole-self dump).
- **Bus:** `@manager` ops emit on the real `dharma_*` bus (explicit today, compiles) — same transport as the swarm (`wt/swarm-ccr`).
- **STAGED (not guessed — needs the cognition-engram rebuild to verify link):** auto-injecting telemetry/interoception + bus emission at the decorated boundary (`cg_fn` diff in `SEAM_STAGED.md`); building the cognition engram with `surface.el` compiled in. No promote to live, no cutover (per rails).

# Decorator-as-seam — what WAS staged (with the exact diff)
The reshape rests on one idea: **the decorator boundary is the single interception
seam.** Decorate a function with its `@route` + VBD role and the fabric gives, for
free: (1) the served route, (2) telemetry + interoception emitted at the boundary,
(3) indirection through a swappable event bus. Ground-truth of each, with the
minimal change to close the gaps.
## Ground truth (file:line)
| seam | real today? | evidence |
|------|-------------|----------|
| **route → served** | **REAL once `@route` codegen is in elc** | Base engram uses hand dispatch: `http_serve(port,"handle_request")` + if-else `handle_request` — `engram/src/server.el:592,742`. VBD decorators inert: only a negative check `#error if dharma_emit outside @manager` — `codegen.el:2929-2934`; `lang/spec/language.md:449` "decorators with structural meaning today: none". `@route(path,method,kind,suffix)` synthesizes `el_route_dispatch` — `codegen.el:3500-3852` — but only on **unmerged** `feat/el-route-decorators`. **This session ported it into the worktree elc and PROVED decorate→serve** (`route_proof.el` on :8951; `surface.el` compiles, dispatcher generated for all 8 ops). |
| **telemetry + interoception at boundary** | **NOT wired** | Afferent counters (`_eg_aff_node_creates++`), `engram_strengthen`, `engram_chrono_tick` fire *inside engram builtins* + explicit routes (`route_strengthen`, `route_tick`) — not at the El fn boundary. `cg_fn` (`codegen.el:2919`) injects zero instrumentation. |
| **bus indirection** | **bus REAL; auto-indirection NOT** | `dharma_emit/dharma_field` is a real event bus (per-type blocking queue, `/dharma/event`) — `el_runtime.c:11685-11987`. Same transport the swarm uses (`wt/swarm-ccr`: `dharma_emit/field` + `dharma_connect/send/activate`). `@manager` *may* call it (enforced) but decoration does not auto-insert it. `surface.el` calls it explicitly today (correct, compiles). |
## The minimal change — auto-emit at the decorated boundary
Inject a prologue in `cg_fn` (right after the C signature line) keyed on the VBD
role decorator. This makes telemetry + interoception + bus **automatic** at the
seam, so handlers no longer write explicit `dharma_emit` (DRY), and every decorated
op self-senses.
```el
// lang/el-compiler/src/codegen.el — in cg_fn, after:
// emit_line("el_val_t " + fn_name + "(" + params_c + ") {")
// insert:
let role: String = stmt["decorator"] // manager|accessor|engine (stacks with @route)
if str_eq(role, "manager") || str_eq(role, "accessor") {
// (2) INTEROCEPTION — the mind senses its own op firing (chronoception tick;
// afferent count is incremented inside the builtins the body then calls).
emit_line(" engram_chrono_tick();")
}
if str_eq(role, "manager") {
// (1)+(3) TELEMETRY + BUS — provenance emitted through the swappable dharma
// transport (same bus the swarm peers field on). Payload = op name; a
// richer payload (timing, args) is a follow-up once the boundary carries them.
emit_line(" dharma_emit(EL_STR(\"neuron.op." + fn_name + "\"), EL_STR(\"\"));")
}
```
Rationale for the exact calls:
- `engram_chrono_tick()` — zero-arg, already the interoception primitive
(`route_tick` → `engram_chrono_tick`); safe to fire per decorated op.
- `dharma_emit(event, payload)` — the real bus (`el_runtime.c:11928`), signature
`(String,String)->Void`; the swarm fields on the same bus, so **one transport**.
- `engram_strengthen(node_id)` is intentionally **not** auto-injected here: it needs
the touched node-id, which isn't uniform at fn entry. Strengthening stays inside
the accessor's builtins (where the id exists); the boundary adds the *tick* +
*emit*, not the id-specific strengthen.
## Why this is STAGED, not shipped this session
`dharma_emit` / `engram_chrono_tick` / `engram_strengthen` link **only in the
engram+dharma runtime**. A standalone El service (`route_proof.el`) cannot link
them, so the auto-injection can only be *verified* by rebuilding the **cognition
engram** (server.el + the geometry/cognition `el_runtime.c` from
`feat/cognitive-architecture`) with the modified elc and running it on the clone
`:8900`. That rebuild is a multi-branch integration + a delicate ~3.5 MB C build
(AGENTS.md warns of 27 GB OOM on folded builds). Per the rails — *"a compiler change
we get subtly wrong is worse than one we stage for review"* — the boundary
injection is staged as this reviewable diff rather than guessed into the shipped
toolchain. The **route** half of the seam is already proven end-to-end.
## Verification plan (when the boundary injection is approved)
1. Apply the `cg_fn` diff in the worktree; rebuild elc self-host (proven fast: ~3 s + ~1 s cc).
2. Integrate `feat/cognitive-architecture` engram runtime + `surface.el` into the worktree server; build the engram binary with the new elc.
3. Run THAT binary as the clone daemon on `:8900` (WAL-aside cold-boot + `ENGRAM_WAL=on`, gate-1 recipe). Live `:8742` untouched.
4. Drive `neuron.think/attend/learn` and assert: a `neuron.op.*` event is fielded on the dharma bus and the chronoception counter advances per call — telemetry+interoception+bus, automatic, at the decorated boundary.

#!/usr/bin/env bash
# parity.sh — proves the reshaped Neuron surface against an ISOLATED engram clone.
#
# The reshape collapses ~90 noun-CRUD MCP tools into a handful of geometry ops
# (read / write / relate / supersede) plus the LIVE agentic primitives already in
# the engram cognition build (think / attend / learn=correspondence-beat /
# ground / assert). Type is a parameter, not a tool-per-noun.
#
# HONEST SCOPE. Verified live-runtime facts on the nsbx HTTP-daemon clone
# (confirmed identically on the peer clone :8901):
# * reads (search/activate/neighbors/nodes) + attend + assert -> serve real results.
# * think / ground / learn -> route reachable,
# but the CENTERED GEOMETRY is not primed in the HTTP daemon boot on a clone,
# so they return {"error":"geometry unavailable"}. The one operation IS
# compiled + validated via the C cog-arch harness (nsbx validate: held-Brier
# 0.028648 -> 0.000586 @ 10,994 nodes). This harness therefore proves the
# ROUTE is wired and reports the geometry-gate honestly.
# * paged-store node-write (POST /api/nodes) crashes the daemon on a WAL-less
# cold-boot clone, so write/supersede are NOT executed here (route wired;
# marked EXEC-SKIP to avoid killing the clone). They are exercised on a
# write-healthy store (live prod / a checkpoint-consistent clone).
