fix(mcp-wrapper): declare real input schemas so tool args actually bite

The cognitive-graph and write tools advertised an empty inputSchema
({"properties":{}}), so MCP clients never sent entity_id/depth/query/
from_id/node_id etc. Graph reads fell back to the full neighborhood
(480-775KB, over transport limits) and write tools (forget, linkEntities,
evolveMemory) had no way to target a node.

- Declare per-tool JSON-Schemas matching the params each soul handler
  already accepts (76 of 87 tools; 11 are genuinely param-less).
- Read + forward the declared args: inspectGraph now honors depth (was
  reading only legacy max_depth), compact (default on), snip, k;
  traverseGraph accepts entity_id and defaults compact on so a depth-2
  walk stays bounded; retrieveKnowledge forwards depth/snip/k.
- compact_flag() reads the raw JSON token so an integer 0 / false / "0"
  opts out correctly (json_get_string could not see an integer and
  silently forced compact back on).

Builds on PR #149's compact projection; keeps the relevance-ranked
bound on by default for graph neighborhoods.

+//
+// WHY THIS EXISTS (2026-08-07 self-review, measured on the live system).
+// Yesterday's eligibility-trace fix made Hebbian learning work: hebb_max
+// 0.000799 -> 0.4725, and 1,198 hebbian-associate edges formed in 23h48m.
+// A census this morning found all 1,198 of them living in this process's RAM
+// and nowhere else:
+//
+//   soul daemon in-process graph:   42,426 edges, 1,198 hebbian
+//   engram server (:8742, durable): 41,213 edges,    49 hebbian
+//
+// The soul pulls from the server every 10 min (GET /api/sync) and never
+// pushes. It also cannot save its own snapshot: soul.el only sets
+// soul_snapshot_path inside `if is_genesis && safe_to_seed`, and safe_to_seed
+// is unconditionally false when ENGRAM_URL is set — which it is, in the
+// launchd plist — because the HTTP server owns persistence and a soul writing
+// snapshot.json would clobber it. That guard is right. So mem_save() below has
+// literally never run, and this daemon (the ONLY process doing idle cognition,
+// therefore where essentially all co-activation happens) was throwing away
+// every association it learned, every restart, silently.
+//
+// The fix is not to let the soul write the file. It is to make consolidation a
+// message: hand each newly-formed edge to the durable store over the API the
+// server already exposes. Fast volatile store learns online; slow durable store
+// keeps what cleared the threshold. Only edges past ENGRAM_HEBB_LINK_MIN are
+// ever queued, so what crosses the boundary already earned it.
+//
+// Failure is non-fatal by construction: a drained entry that fails to POST is
+// gone, and that is fine — a real association re-forms from live co-activation.

+# Neuron — Architecture Overview
+
+> Status: living document. Grounded in the committed source of the `neuron`
+> repository as of 2026-08-10. Every structural claim cites a real file. Where a
+> statement is inferred rather than read directly, it is labelled *(inference)*
+> or *(unverified/TODO)*.
+
+## What Neuron is
+
+Neuron is a **persistent CGI (Cultivated General Intelligence) runtime**. It is
+not a chatbot and not a stateless API in front of an LLM. It is a long-lived
+process that *remembers* — it carries an identity, a graph of memory and
+knowledge, and an autonomous idle-cognition loop across restarts. The LLM is one
+resource it calls; the durable part is the **engram** (the graph) and the
+**soul** (the program that reasons over it).
+
+Three things run together to make that true:
+
+- **The soul** — the compiled El program in this repo. It owns the HTTP surface,
+  the cognitive API, the request pipeline (`layered_cycle`), and the autonomous
+  awareness daemon. Entry point `soul.el`, served by `handle_request`
+  (`routes.el:358`).
+- **The engram** — the graph store. Node/edge model, spreading activation, and
+  Hebbian co-activation physically live in the shared El runtime
+  (`el_runtime.c`); `engram/src/server.el` is a thin HTTP face on `:8742`. The
+  engram is a *sibling* repo (`foundation/el/engram`), compiled and co-located at
+  runtime, not part of this repo's source tree.
+- **The El runtime** — `el_runtime.c` / `el_runtime.h`. Every compiled El binary
+  links it. It implements all builtins (`engram_*`, `http_*`, `json_*`, LLM,
+  crypto) and *is* the database — "no SQL, no db layer, no SQLite"
+  (`../foundation/el/engram/src/server.el:4-6`).
+
+Neuron persists memory itself — this repo is the memory system. Do not confuse
+it with the Neuron desktop/UI application, which is **out of scope** here and is
+only ever a *client* of the MCP surface described in this set.

+(`NEURON_PORT`, k8s `deployment-blue.yaml`); engram `:8742` (`entrypoint.sh`,
+`server.el:711`). The Axon backend, `neuron-connectd` (`:7771`), and the LLM are
+external dependencies the soul reaches over HTTP (`routes.el` `axon_get/post`,
+`connectd_get/post`).
+
+## The two external interfaces
+
+Neuron exposes exactly two surfaces, and it is worth being precise about the
+difference because they drive the whole component split:
+
+1. **The MCP surface** — the *tool* interface. MCP clients call tools
+   (`begin_session`, `remember`, `search_knowledge`, `inspect_graph`,
+   `cultivate`, …). This is the interface Claude Code and agents use. It is
+   delivered by the **proxy → wrapper** chain, which translates MCP JSON-RPC
+   into the soul's HTTP REST calls. The wrapper carries a catalog of ~90 tools
+   (`mcp-wrapper/src/main.el`).
+
+2. **The HTTP API** — the *cognitive* interface. The soul serves REST on
+   `:7770`. `routes.el` dispatches; `neuron-api.el` handles the cognitive
+   endpoints (`/api/neuron/*`). This same surface backs the chat product
+   (`/api/chat`, `/api/sessions`) and the studio UI (`/`).
+
+In production the MCP client connects to the soul's HTTP directly — the
+`neuron-mcp` ClusterIP Service targets `:7770` (`service.yaml`) and the
+proxy/wrapper chain is primarily the **local developer adapter** that lets a
+stdio MCP client speak to an HTTP soul. See `04-runtime-and-deployment.md`.
+
+## Component map (summary)
+
+The full VBD classification is in `01-vbd-decomposition.md`. In one glance:
+
+| Layer | Module(s) | Role |
+|---|---|---|
+| HTTP dispatch | `routes.el` | Manager — hand-written method/path dispatch |
+| Cognitive API | `neuron-api.el` | Managers + Engines — session/memory/knowledge/graph/cultivation handlers |
+| Request pipeline | `soul.el` `layered_cycle` | Manager — L1 safety → L2 stewardship → L3 imprint |
+| Boot + identity | `soul.el` | Manager — compose layers, seed identity graph, start server + daemon |
+| Autonomous cognition | `awareness.el` | Manager (`awareness_run`) + Engines (curiosity, attend, threat) |
+| Memory access | `memory.el` | Resource Accessor over the engram FFI/HTTP |

+| Request-layer rules | `safety.el`, `stewardship.el`, `imprint.el` | Engines |
+| Conversation sessions | `sessions.el` | Manager (chat product) |
+| MCP transport | `mcp-proxy`, `mcp-wrapper` | Managers/Accessors — protocol boundary |
+| Build | `manifest.el`, `dist/soul.c`, El toolchain | amalgamation → `soul.c` → binary |

+## Reading guide
+
+- **`01-vbd-decomposition.md`** — the volatility analysis. Start here for *why*
+  the boundaries fall where they do. Contains the full Manager/Engine/Accessor/
+  Utility table and the honest list of where the real code diverges from VBD.
+- **`02-components.md`** — per-subsystem detail: routing, the cognitive API, the
+  memory & activation engine, the MCP transport chain. Read after 01.
+- **`03-data-and-memory.md`** — the engram graph model: node/edge structs,
+  layers, the two tier systems, write-protection, tombstone/supersede
+  immutability, persistence.
+- **`04-runtime-and-deployment.md`** — process/port topology, the end-to-end MCP
+  request path, local vs GKE blue/green, secrets/config.
+- **`05-el-and-build.md`** — the El language, the `elc`/`elb` toolchain, the
+  amalgamation → `soul.c` → binary pipeline, and the compile-time capability
+  gates.
+
+## A note on honesty
+
+Two facts shape everything below and are stated once here so the rest reads
+straight:
+
+1. **The most volatile logic — the activation and Hebbian math — lives in the
+   most stable-looking layer**, the C runtime (`el_runtime.c`). The El files in
+   this repo are largely a *Manager + Accessor shell* around that core. This
+   inverts the usual VBD expectation and is called out wherever it matters.
+2. **The immutability guarantee lives above the store, not in it.** The engram
+   HTTP server will hard-delete a node (`DELETE /api/nodes/:id` →
+   `engram_forget`, `server.el:322`). Immutability holds only because the
+   neuron-api / MCP layer routes every user-facing delete through *tombstone*
+   instead (`memory.el:46`). The invariant is a policy, not a property of the
+   accessor.

+# Neuron — VBD Decomposition

+> question — **what changes, why, and how often** — and draws component
+> boundaries around the answers so that a change lands inside one component
+> instead of rippling across many.
+>
+> VBD's component taxonomy:
+> - **Managers** — stable orchestrators. They sequence use-cases and delegate;
+>   they change only when the *shape* of a workflow changes.
+> - **Engines** — volatile business rules. The "how" that churns.
+> - **Resource Accessors** — isolate an external dependency (a store, an API) so
+>   its volatility can't leak inward.
+> - **Utilities** — cross-cutting, low-volatility helpers.
+>
+> Communication ideal: Managers orchestrate Engines and Accessors; Managers
+> prefer async/event coupling to each other; Engines are stateless-ish and never
+> reach external I/O directly; Accessors hide all I/O. We note below where neuron
+> honors this and where it doesn't.
+
+## The axes of change
+
+Before classifying modules, name the volatility. These are the axes along which
+neuron actually changes, ranked by observed churn (dated self-review comments in
+the source are the evidence — the code keeps a changelog in its own margins).
+
+### 1. Context / payload shaping — *highest churn*
+How much of the graph, and in what projected form, gets returned to a
+bounded MCP response. The `begin_session` / `compile_ctx` handlers and the
+`api_compact_*` helpers carry dense dated review comments (2026-07-30, -31)
+documenting repeated rework after unbounded payloads closed the MCP client
+socket (`neuron-api.el:90-317`). This changes because the *client's* context
+budget and the *shape* of "what's relevant right now" keep moving. The newest
+rework in this axis is the **relevance-ranked neighbor projection**
+(`api_compact_neighbors` + `api_neigh_*`) behind `inspect_graph`'s `compact=1`
+path — it is what keeps *self-load* (traversing the high-fanout identity anchors)
+from closing the socket. It is committed source, compiled into `dist/soul.c`.
+
+### 2. Autonomous-cognition policy
+What the idle soul chooses to think about: seed-domain selection, curiosity
+rotation, novelty gating, and the inbox verb-mapping in `attend()`. The
+`proactive_curiosity` / `auto_term_try_slot` machinery
+(`awareness.el:590-876`) has the deepest git-archaeology in the codebase
+(comments spanning 2026-05 → 2026-08). This is where the *behavior* of the
+agent is tuned.
+
+### 3. Epistemic & memory semantics
+Tiers, salience mapping, promotion/consolidation, the immutability policy
+(tombstone/supersede), and knowledge disposition. These evolve as the memory
+*philosophy* matures — e.g. `mem_forget` becoming a soft delete
+(`memory.el:70`), the salience-evolution pass in `mem_consolidate`
+(`memory.el:92-133`), the supersede-edge pattern (`neuron-api.el:394-428`).
+
+### 4. Safety & stewardship rules
+Crisis bell thresholds, agentic threat scoring, mission alignment, CGI
+continuity fingerprinting. `safety.el`, `stewardship.el`, and the threat
+scorer grafted onto `awareness.el:1286-1419` change on behavioral/regulatory
+pressure, independently of everything else.
+
+### 5. API / route surface growth
+New cognitive endpoints and their dispatch. `routes.el` grows structurally as
+tools are added; the `handle_request` if/else chain (`routes.el:358-753`) is
+edited on every surface change.
+
+*(A sixth axis — the activation/Hebbian numeric math — is real and volatile but
+is externalized to `el_runtime.c`. See "Divergences," point 6.)*
+
+## The component map
+
+Modules classified against the taxonomy, with the volatility that justifies each
+placement. Paths are repo-relative unless noted `foundation/…`.
+
+### Managers (stable orchestration)
+
+| Module / function | File | Why a Manager |
+|---|---|---|
+| `handle_request` | `routes.el:358-753` | Top-level HTTP dispatcher. Pure method/path routing; delegates every body of work. Changes only when the *route surface* (axis 5) changes, not when logic changes. |
+| Boot sequence | `soul.el:508-627` | Sequences load → seed → identity → serve → daemon. Highest stability; changes only on architecture shifts. |
+| `layered_cycle` | `soul.el:382-506` | Request use-case pipeline: L1 safety → L2 stewardship (continuity, mission, affect) → L3 imprint → L1 output validation. Orchestrates Engines; holds no rules itself. |
+| `awareness_run` / `one_cycle` | `awareness.el:1097-1284`, `1041-1095` | Daemon lifecycle + the perceive→attend→respond→record sequencer. Manager of the autonomous loop. |
+| Session CRUD | `sessions.el` | Orchestrates the immutable delete-then-recreate dance for conversation sessions (chat product). Manager-flavored, but leaks store detail (see Divergences). |
+| MCP proxy | `mcp-proxy/src/main.el` | Orchestrates transport: accept stdio, forward, retry, health-gate, wrap errors. |
+| MCP wrapper | `mcp-wrapper/src/main.el` | Orchestrates the JSON-RPC ⇄ REST translation, tool catalog, lifecycle (`initialize`/`tools/list`/`tools/call`). |
+
+### Engines (volatile business rules)
+
+| Module / function | File | Volatility it absorbs |
+|---|---|---|
+| `api_compact_*`, `begin_session`, `compile_ctx` | `neuron-api.el:90-317` | Axis 1 — context/payload shaping. The single most-reworked logic on the API side. |
+| `attend()` | `awareness.el:926-973` | Axis 2 — inbox content → action-verb ruleset. |
+| `proactive_curiosity`, `auto_term_try_slot` | `awareness.el:590-876` | Axis 2 — seed selection, stopword/IDF gates, tabu ring. Textbook Engine: highest churn. |
+| threat scoring | `awareness.el:1286-1419` | Axis 4 — additive command/path/history threat rules. |
+| `safety.el` (crisis/harm/bell) | `safety.el` | Axis 4 — crisis screening, bell thresholds, output validation. |
+| `stewardship.el` | `stewardship.el` | Axis 4 — mission alignment, CGI check, continuity fingerprint. |
+| `imprint.el` | `imprint.el` | Axis 2/3 — persona response + knowledge/memory surfacing per imprint. |
+| `mem_consolidate` | `memory.el:92-133` | Axis 3 — which nodes to strengthen; salience-evolution rules. |
+| salience/importance mapping | `neuron-api.el` (repeated in `remember`, `node_create`, `evolve_memory`, `cultivate`) | Axis 3 — importance-enum → salience float mapping. |
+| chat mode selection | `chat.el` (via `routes.el:433-440`, `597-604`) | plan / agentic / `layered_cycle` routing. |
+| **activation + Hebbian math** | `foundation/.../el_runtime.c` | Axis 6 — the true cognitive Engine, externalized to C. |
+
+### Resource Accessors (isolate external I/O)
+
+| Accessor | File | Dependency isolated |
+|---|---|---|
+| `mem_*` | `memory.el` | The engram FFI/HTTP. **The** memory Accessor — clean, single isolation point; every forget routes through `mem_tombstone` (`memory.el:46`). |
+| `engram_*` builtins + `server.el` | `el_runtime.c`, `foundation/el/engram/src/server.el` | The graph store over HTTP `:8742`. |
+| `axon_get` / `axon_post` | `routes.el` | The Axon backend (backlog, artifacts, projects, memories, non-neuron knowledge). |
+| `connectd_get` / `connectd_post` | `routes.el:303-324` | `neuron-connectd` bridge (`:7771`). |
+| `llm_call_system` / `llm_call_agentic` | runtime builtins (used in `routes.el:115`, chat) | The LLM. |
+| `ise_post`, `hebb_consolidate` | `awareness.el:101-148`, `64-99` | Durable engram HTTP (`/api/neuron/state-events`, `/api/edges/batch`). |
+| `render_studio` | `studio.el` | The UI surface. |
+
+### Utilities (cross-cutting, stable)
+
+`flag_true`, `strip_query`, `err_404/405` (`routes.el:14-91`);
+`api_json_escape`, `api_query_param/int`, `api_ok/err`, `api_nonempty`,
+`api_utf8_trunc`, `api_persisted` (`neuron-api.el:45-201`); `idle_*`/`pulse_*`
+counters, `elapsed_ms/human`, `make_action`, `embed_ok` (`awareness.el`);
+`session_make_content`, `aff_try_slot`, JSON builders (`sessions.el`, `soul.el`).
+Beneath all of these, the El runtime builtins (`json_*`, `http_*`, crypto, time)
+are the utility substrate every module shares.

+```
+
+Two things about coupling:
+
+- **Manager → Engine/Accessor is in-process and synchronous** (direct El calls),
+  which matches VBD: rules and I/O sit behind the Managers.
+- **Manager ↔ Manager is *not* the VBD async-event ideal.** It is synchronous
+  HTTP (soul → engram, soul → Axon) plus one genuine event-ish channel: the
+  **engram inbox**. The awareness daemon `perceive()`s by polling a
+  `soul-inbox-pending` tag and consumes trigger nodes
+  (`awareness.el:900-924`, `1090-1093`), and modules communicate asynchronously
+  by writing **InternalStateEvent** nodes. That is a partial actor/event
+  pattern, realized through the graph rather than a message bus.
+
+## Where reality diverges from VBD (call it out)
+
+Honest deviations, so no one reads this doc as a conformance certificate:
+
+1. **No route table.** Dispatch is a hand-written if/else chain in
+   `handle_request` (`routes.el:358-753`); there is no `register-route`
+   registry. Path params are sliced by hand (`str_slice` + `str_index_of`,
+   `routes.el:508-513, 539-541`) — one site carries an inline offset bug-fix
+   comment. Acceptable for a single dispatcher, but it means the "route surface"
+   Manager is edited manually on every change.
+
+2. **Store I/O leaks into Managers.** `routes.el` inlines engram export logic for
+   `/api/graph/edges` (`routes.el:394-422`, with a 2026-08-07 comment about a
+   read-route that corrupted the canonical snapshot). The `awareness_run` sync
+   block inlines `http_get /api/sync` + `engram_load_merge`
+   (`awareness.el:1219-1279`). `emit_heartbeat` (`awareness.el:201-549`, ~350
+   lines) mixes Utility (formatting), Accessor (HTTP/FFI reads), and Manager
+   (state-delta tracking) in one function. These are Accessor responsibilities
+   living inside orchestration — the clearest VBD smell in the codebase.
+
+3. **No authentication.** The only access control on the HTTP surface is per-IP
+   rate limiting (`routes.el:38-75`) plus `is_protected_node` on 15 hardcoded
+   identity IDs (`neuron-api.el:20-37`). There is no bearer/token check in the
+   dispatch path. Security is a cross-cutting concern only partially realized;
+   the deployment relies on a **single-trusted-client, internal-only** boundary
+   assumption (the `neuron-mcp` Service is ClusterIP, no external LB — see doc 04).
+
+4. **Immutability is enforced above the Accessor, not in it.** The engram store
+   itself hard-deletes (`DELETE /api/nodes/:id` → `engram_forget`,
+   `server.el:322`). The invariant "we never delete, we tombstone/supersede"
+   is a *routing policy* in `memory.el` / `neuron-api.el`, not a property of the
+   store. A caller that hits the raw engram HTTP bypasses it.
+
+5. **Mutation via delete-then-recreate.** Because nodes are immutable,
+   `sessions.el` mutates a session by deleting and recreating the node — flagged
+   non-atomic in its own comments (`sessions.el:303-308`, `:456`).
+
+6. **The volatile core is in the stable layer.** The activation, decay, and
+   Hebbian co-activation math — genuinely high-volatility numeric policy — lives
+   in `el_runtime.c`, the foundational runtime every binary links. The El files
+   here are a Manager+Accessor shell around it. This inverts VBD's usual
+   layering (volatile logic should sit *above* stable infrastructure) and is the
+   single most important thing to understand before changing memory behavior:
+   you often can't, from this repo, without touching `foundation/el`.
+
+7. **Vocabulary mismatch across layers.** The MCP-facing memory vocabulary
+   (tiers `note → lesson → canonical`, disposition
+   `experimental → … → deprecated`, importance enum `low/normal/high/critical`)
+   is **not** the engine's model. The engine uses cognitive tiers
+   `Working / Episodic / Semantic / Canonical` (a `tier` string field) plus
+   continuous `salience`/`importance`/`confidence` floats, and stores epistemic
+   tier/disposition as **tags** (`tier:canonical`, `disposition:stable`), not as
+   enforced state (`neuron-api.el:533`, `server.el:519-522`). The mapping is a
+   convention, not a guarded state machine. See `03-data-and-memory.md`.
+
+## Testing spiral (VBD heuristic, as observed)
+
+VBD recommends testing Engines first (pure logic), then Accessors (mock I/O),
+then Managers (integration). The repo has `tests/*.el` matching this instinct —
+`test_safety.el`, `test_bell_safety.el` (Engines), `test_layer_contract.el`
+(the Manager↔Engine JSON contract `layered_cycle` depends on), `test_soul_guard.el`
+(the boot Manager's seed guard), `test_sessions.el`. **Flag:** CI compiles and
+smoke-tests only (`dist/neuron --help`); it does **not** run these `.el` suites
+(`ci.yaml`). Whether they gate merges elsewhere is unverified — see doc 05.

+> boundaries read `01-vbd-decomposition.md` first; this doc is the *what* and
+> *how*, grounded in file citations.
+
+---
+
+## 1. Routing / dispatch — `routes.el`
+
+**Responsibility:** turn an inbound HTTP request into a handler call. One
+function does it.
+
+- **Entry point:** `handle_request(method, path, body) -> String`
+  (`routes.el:358-753`). Structure: branch by method (`GET` `:384`, `POST`
+  `:549`, `DELETE` `:726`, `PATCH` `:739`), then an ordered sequence of exact
+  (`str_eq`) and prefix (`str_starts_with`) tests against the cleaned path.
+  First match wins. There is **no route table and no `register-route`** — this is
+  a deliberate hand-written dispatcher.
+- **Path params** are extracted manually with `str_slice`/`str_index_of`
+  (session id `:539-541`, typed-node type `:508-513`).
+- **Query strings** stripped up front by `strip_query` (`:77-83`); the raw path
+  (with query) is still passed to handlers that read params.
+- **Pre-dispatch middleware** (cross-cutting, inline): an activity timestamp
+  (`state_set("soul.last_activity_ts", …)` `:367`) and **rate limiting**
+  (`rate_limit_check(ip, path)` `:38-75`, `:372-378`) — a per-IP 60 req/min
+  sliding window, `/health` exempt, loopback skipped, returns a 429 body.
+- **Auth:** none in the dispatch path. See doc 01, Divergence 3.
+- **Fallbacks:** `err_404` / `err_405`.
+
+**Collaborators:** delegates to `neuron-api.el` (`/api/neuron/*`), `sessions.el`
+(`/api/sessions/*`), `chat.el` (`/api/chat`, `/dharma/recv`), the Axon Accessor
+(`axon_get/post` for `/api/backlog|artifacts|projects|memories|knowledge`),
+`connectd_*` (`/api/connectors*`), `studio.el` (`/`), and engram builtins for the
+raw `/api/graph*` reads.
+
+**Route surface** (grouped; full table with line numbers is in the survey notes):
+
+| Group | Representative routes | Handler home |
+|---|---|---|
+| Session/context | `/api/neuron/session/begin`, `/api/neuron/ctx`, `/api/sessions*` | neuron-api, sessions.el |
+| Memory | `/api/neuron/memory`, `/recall`, `/memory/{evolve,forget,delete,update}`, `/node/{create,update,delete}` | neuron-api |
+| Knowledge | `/api/neuron/knowledge/{search,capture,evolve,promote}`, `/knowledge` | neuron-api |
+| Graph/activation | `/api/neuron/graph`, `/graph/link`, `/api/graph*`, `/list/:type` | neuron-api + engram builtins |
+| Cultivation/self | `/api/neuron/cultivate`, `/lineage`, `/imprint/*`, `/synthesize` | neuron-api, routes.el |
+| Processes/config | `/api/neuron/processes{,/define}`, `/config{,/tune}` | neuron-api |

+| Health/UI | `/health`, `/lineage`, `/` | routes.el, studio.el |
+
+---
+
+## 2. The cognitive API — `neuron-api.el`
+
+**Responsibility:** the `/api/neuron/*` handlers — the operations that read and
+write the engram as *cognition* (session, memory, knowledge, graph, config,
+processes, state, cultivation). The file header notes these were migrated **out
+of the MCP wrapper's HTTP calls into in-process engram builtins**
+(`neuron-api.el:3-9`) — so most handlers call the store directly, no HTTP
+round-trip.
+
+**Primary collaborators** are the engram builtins (`engram_node_full`,
+`engram_search_json`, `engram_activate_json`, `engram_scan_nodes_json`,
+`engram_scan_nodes_by_type_json`, `engram_neighbors_json`, `engram_connect`,
+`engram_get_node_json`, `engram_stats_json`, `engram_save`) and `memory.el` for
+tombstoning.
+
+**Handler groups:**
+
+- **Session / context** — `handle_api_begin_session` (`:273-301`),
+  `handle_api_compile_ctx` (`:305-317`). Pull `engram_stats_json`, run
+  spreading activation (`engram_activate_json`, depth-1 for begin, depth-2 for
+  ctx), scan recent `InternalStateEvent`s, then **project the result through the
+  compaction helpers** so the payload can't overflow the MCP client's context.
+  This is Engine work (axis 1) inside a Manager-shaped entry point.
+
+- **Memory** — `handle_api_remember` (`:322-348`): maps `importance` → salience,
+  injects a `project:<name>` tag, writes a `Memory`/`Episodic` node, then
+  **read-back-verifies** persistence (`api_persisted`). Deletes are **tombstone,
+  never hard delete** — `node_delete` / `memory_delete` / `forget` all route
+  through `tombstone_node` → `mem_tombstone`. Updates/evolves are **immutable
+  supersede** — `node_update` (`:397-429`), `evolve_memory` (`:711-735`) create a
+  new node and wire `engram_connect(new, old, "supersedes")`.
+
+- **Knowledge** — `search_knowledge` (`:458-478`, falls back to
+  `engram_activate_json(q,2)` when lexical search returns nothing),
+  `browse_knowledge`, `capture_knowledge` (`:492-504`), `evolve_knowledge`,
+  `promote_knowledge` (`:526-542`, writes a canonical-tier node + supersede
+  edge). Evolve/promote respect `is_protected_node`.
+
+- **Graph** — `handle_api_inspect_graph` (`:778-813`): resolves a named anchor
+  (`self`/`neuron` → `kn-efeb4a5b…`, `values` → `kn-5b606390…`) or an explicit
+  id, then `engram_neighbors_json(resolved, depth, "both")`. By default this is a
+  plain neighbor traversal (byte-identical to the old behavior, so the studio app
+  is unaffected). **When called with `compact=1` (or `true`) it returns a
+  relevance-ranked projection** (`:804-810`): the neighborhood is ranked and the
+  top **`k`** neighbors (default 12) keep a UTF-8-safe content snippet (default
+  `snip=600`) via `api_neigh_full`, while the remainder collapse to lightweight
+  `{id,label,node_type,tier,edge,pointer:true}` stubs via `api_neigh_pointer`.
+  This bounds a high-fanout identity anchor (voice, writing-imprint, self-root)
+  from ~670 KB to ~25 KB so the MCP transport no longer socket-closes on
+  self-load. The MCP wrapper appends `&compact=1` on its inspectGraph/fetch-by-id
+  path; the studio app omits the flag and is unchanged.
+  `handle_api_link_entities` (`:818-…`) creates edges but blocks edges *into*
+  protected nodes.
+
+- **Cultivation** — `handle_api_cultivate` (`:781-839`): dispatches on
+  `operation` (evolve_knowledge / evolve_memory / forget / link_entities) and
+  performs the same engram ops **but skips `is_protected_node`** — the sanctioned
+  identity-write path, gated by convention to Will's explicit cultivation
+  sessions.
+
+- **Config / processes / state-events / consolidate** — config anchors + a
+  `ConfigEntry` node search (`:616-639`), `tune_config` (`:642-653`),
+  `browse_processes` / `define_process` (`:547-568`), state-event log/list
+  (`:575-610`), and `consolidate` (`:855-880`, an `engram_save` snapshot plus an
+  optional `SessionSummary` node).
+
+**The projection/compaction layer** (a real, recurring concern) lives in
+`api_compact_node` (`:132-148`), `api_compact_node_array` (`:152-165`),
+`api_compact_activated` (`:170-189`), and `api_utf8_trunc` (`:116-127`). These
+**cap array length and truncate each node to identity + a bounded UTF-8-safe
+content snippet.** Their consumers are `begin_session` and `compile_ctx`.
+The design principle is the important part: *the API returns a relevance-bounded
+projection of the graph, not the graph.* That bounding started as
+length-capping + activation-ordering; it now also includes a **relevance-ranked
+neighbor projection** — `api_compact_neighbors` (`:288-317`), backed by
+`api_neigh_better`/`api_neigh_rank` (relevance ordering), `api_neigh_full`
+(top-K, snippet), `api_neigh_pointer` (the rest, stub), and `api_float_or`. This
+is **committed fact, not an in-flight concern**: it is the `compact=1` path of
+`handle_api_inspect_graph` above, and it is what makes self-load survive the MCP
+transport. It is compiled into `dist/soul.c` (this PR regenerated the
+amalgamation so CI ships it — see doc 05).
+
+---
+
+## 3. Memory & activation engine
+
+This subsystem spans three files in this repo (`memory.el`, `awareness.el`,
+`soul.el`) and one in `foundation` (`el_runtime.c`). The split matters: **the
+math is in C; the El files orchestrate, persist, and instrument it.**
+
+### 3a. Memory access — `memory.el` (the Accessor)
+
+The single isolation point over the engram FFI. Key functions:
+
+| Fn | Lines | Backing call | Notes |
+|---|---|---|---|
+| `mem_store` | `5-28` | `engram_node_full` + read-back | verified write |
+| `mem_remember` | `30-32` | `mem_store` | label `soul-memory` |
+| `mem_recall` | `34-36` | `engram_activate_json(query, depth)` | **spreading-activation recall** (mutates WM) |
+| `mem_search` | `38-40` | `engram_search_json` | pure lexical scan (no WM side-effect) |
+| `mem_strengthen` | `42-44` | `engram_strengthen` | salience bump |
+| `mem_tombstone` | `52-62` | `engram_node_full` + `engram_connect` | the one canonical soft-delete |
+| `mem_forget` | `70-72` | `mem_tombstone` | soft delete (no longer hard) |
+| `mem_consolidate` | `92-133` | `engram_wm_top_json`, `engram_strengthen` | salience-evolution pass |
+| `mem_save` / `mem_load` | `135-148` | `engram_save/load` | snapshot I/O |
+
+Note the distinction between **recall and search**: `mem_recall` fires spreading
+activation (and warms working memory as a side effect); `mem_search` is a passive
+lexical lookup. Tiers here are `tier_working` / `tier_episodic` / `tier_canonical`
+(`memory.el:1-3`) — see doc 03 for how these relate to the engine's tier field
+and to the MCP surface vocabulary.
+
+### 3b. Autonomous cognition — `awareness.el` (the daemon)
+
+`awareness.el` is the **idle-cognition daemon plus observability**, not
+emotional-state code. `awareness_run()` (`:1097-1284`) is the master loop,
+launched last from `soul.el:627`. Each tick (`SOUL_TICK_MS`, ~200ms):
+
+1. **`one_cycle()`** (`:1041-1095`) — the cognitive step:
+   `perceive()` (`:900-924`, gated on a `soul-inbox-pending` tag, then
+   `engram_activate_json`) → `attend()` (`:926-973`, parse trigger content into
+   an action verb: remember / search / activate / strengthen / forget /
+   consolidate / respond) → `respond()` (`:975-1029`, dispatch to the `mem_*`
+   fns) → `record()` (`:1031-1039`, emit an InternalStateEvent) → consume the
+   trigger.
+2. **Heartbeat** (every 60s): `hebb_consolidate()` **then** `emit_heartbeat()`
+   then `mem_save` snapshot (`:1189-1197`).
+3. **Curiosity scan** (every 30s when idle): `proactive_curiosity()`
+   (`:701-876`) rotates 4 seed-domain sets, activates a seed, strengthens the
+   top result **only if it changed** (novelty-gated), and derives an
+   autobiographical seed from the top-10 working-memory nodes with
+   stopword/IDF/tabu filtering.
+4. **Engram sync** (every 10 min): `GET /api/sync` → `engram_load_merge` →
+   telemetry prune.
+
+Two functions carry most of the file's weight and volatility:
+- **`hebb_consolidate()`** (`:64-99`) — the durable-learning write-back. It drains
+  newly-formed co-activation edges (`engram_hebb_drain_json(64)`) and POSTs them
+  as one batch to `/api/edges/batch` (`:94`). The comment block (`:33-63`)
+  records that before this path existed the soul threw away ~1,198 learned
+  edges per restart — the daemon is where **essentially all co-activation
+  happens**, and this is how it survives.
+- **`emit_heartbeat()`** (`:201-549`, ~350 lines) — assembles ~50 gauges (WM
+  saturation/churn, Hebbian candidate/edge counts, embedding coverage, corpus
+  health) into one ISE. Pure observability; a fat, churny Accessor/Utility mix.
+
+A **threat scorer** (`:1286-1419`) is grafted onto the end — command/path/history
+additive scoring, ≥70 blocks a tool call. Cross-cutting agentic-safety policy,
+unrelated to memory mechanism.
+
+### 3c. Identity & the request pipeline — `soul.el`
+
+`soul.el` is the top-level program (`cgi "neuron-soul"`, `:12-17`) and imports
+every other module (`:1-10`). It owns:
+
+- **The identity graph.** `init_soul_edges()` (`:19-92`) hard-wires a `self_root`
+  node linked by `identity` edges (weight 0.95) to family/origin/value nodes,
+  plus a dense `co-value` mesh (weight 0.7) among 8 value nodes.
+  `ensure_self_canonical_bridge()` (`:101-110`) links the public traversal-root
+  anchor (`kn-efeb4a5b`) to the curated self node via `canonical-self` edges.
+  `load_identity_context()` (`:153-240`) loads intellectual-DNA / values /
+  memory-philosophy content into a state key for prompt injection.
+- **Boot orchestration** (`:508-627`): load snapshot → optional first-boot seed
+  (guarded) → identity context → persona-from-env → boot-count increment →
+  session-start event → genesis-only edge init → `http_serve_async(port,
+  "handle_request")` → `awareness_run()`.
+- **The request pipeline.** `layered_cycle()` (`:382-506`) — a 4-layer stack for
+  user input: **L1** safety screen (`safety_screen`) → **L2a** continuity/
+  behavioral (`steward_session_check`) → **L2b** mission alignment
+  (`steward_align`) → **L2c** affective-context injection → **L3**
+  `imprint_respond` → **L1** output validation (`safety_validate`). Hard-bell
+  inputs bypass the upper layers. The JSON contract between these layers is
+  pinned by `tests/test_layer_contract.el`.
+
+### 3d. Where the activation math actually is
+
+`el_runtime.c` implements the two-layer activation model
+(`background_activation` via BFS fan-out, then `working_memory_weight` via an
+executive filter), ACT-R base-level learning (per-node access-timestamp ring
+buffer), 768-dim semantic embeddings, and Hebbian eligibility traces. Retrieval
+is **spreading activation, not query**:
+`strength = parent_strength × edge_weight × target_salience ×
+cosine(query, target)`. The El files never compute this — they seed it
+(`engram_activate_json`), harvest it (`engram_hebb_drain_json`), and persist it.
+See `03-data-and-memory.md`.
+
+---
+
+## 4. The MCP transport chain — `mcp-proxy`, `mcp-wrapper`
+
+The chain exists because two boundaries vary independently: the *client
+transport* (stdio MCP JSON-RPC) and the *soul's protocol* (HTTP REST). Each hop
+absorbs one.
+
+- **`mcp-proxy/src/main.el`** (listens `:7779`) — a **byte-forwarder**. It
+  accepts the client connection, forwards to the wrapper, and adds resilience:
+  retry, health-gating, and a well-formed error envelope so a downstream hiccup
+  never surfaces to the client as a broken pipe. It holds no MCP semantics —
+  pure transport orchestration.
+
+- **`mcp-wrapper/src/main.el`** (listens `:17779`) — the **protocol translator**.
+  It speaks MCP JSON-RPC to the client and REST to the soul (`:7770`), owns the
+  MCP lifecycle (`initialize`, `tools/list`, `tools/call`), and carries the
+  **tool catalog** (~90 tools) that clients enumerate. `dispatch_tool_call` maps
+  each tool to a soul REST endpoint. It also fires a **spread-activation side
+  effect** (`fire_activation`) — after relevant calls it issues a `/recall` to
+  warm related nodes, so tool use itself nudges working memory. The tool schemas
+  in the catalog are largely name-only stubs — flag as a place where richer
+  schemas could live.
+
+- **Manifests** (`mcp-proxy/manifest.el`, `mcp-wrapper/manifest.el`) declare the
+  build entry and package metadata for each transport binary.
+
+**End-to-end (one `tools/call`):** client → proxy (`:7779`, forward+retry) →
+wrapper (`:17779`, JSON-RPC→REST, catalog dispatch) → soul (`:7770`,
+`handle_request` → `handle_api_*`) → engram builtins → (HTTP `:8742` when in HTTP
+mode). The response walks back up, and the wrapper may fire a `/recall` warm-up
+on the way. The full sequence is drawn in `04-runtime-and-deployment.md`.
+
+**VBD reading:** proxy and wrapper are Managers of transport; the wrapper is also
+the Accessor that isolates the *MCP protocol* boundary from the soul (the soul
+knows only HTTP). The multi-hop shape is justified: the client transport, the
+protocol translation, and the cognition each change for different reasons and are
+deployed/updated independently.

+
+## Nodes
+
+`EngramNode` — `el_runtime.c:5958-6018+`. Every node carries:
+
+| Field group | Fields | Notes |
+|---|---|---|
+| Identity/content | `id`, `content`, `node_type`, `label`, `tier`, `tags`, `metadata` | all `char*` (`:5959-5965`) |
+| Epistemic weights | `salience`, `importance`, `confidence` (double), `temporal_decay_rate` | per-node decay λ override; 0 = use global (`:5966-5969`) |
+| Access history | `activation_count`, `last_activated`, `created_at`, `updated_at` | `:5970-5973` |
+| Two-layer activation | `background_activation` (Layer 1, BFS fan-out), `working_memory_weight` (Layer 2, executive filter), `suppression_count` | context compilation uses **only** `working_memory_weight` (`:5974-5991`) |
+| Consciousness layer | `layer_id` | default 1 = CORE_IDENTITY (`:5996`) |
+| ACT-R learning | `access_ts[K]` ring buffer, `access_head`, `access_filled`, `wm_anchor` | base-level learning (`:5997-6008`) |
+| Semantics | `emb` (768-dim nomic-embed-text vector, lazily backfilled), `emb_dim` | `:6009-6016` |
+| Hebbian | eligibility trace | `:6017+` |
+
+### Node types are strings, not an enum
+
+`node_type` is a free `char*`, defaulting to `"Memory"` when unset
+(`el_runtime.c:7401`, `server.el:159`). There is **no closed node-type enum** in
+the shipped engine. Two consequences:
+
+- The runtime *special-cases* a handful of type strings for activation
+  thresholds (`engram_type_threshold`, `:5933-5955`): `DharmaSelf`/`Safety`
+  (0.05, fire easily), `Belief`/`Entity` (0.30), `Knowledge` (0.20), everything
+  else `Note`/`Memory`/`Working` (0.40). `InternalStateEvent` and `Tag` are
+  **excluded from working-memory promotion** (`:6674-6676`, `:7368-7370`).
+- Type strings the neuron layer actually writes: `Memory` (default), `Knowledge`
+  (`server.el:549`), `InternalStateEvent` (`server.el:493`), `Tombstone`
+  (`memory.el:55`), `Conversation` (session nodes, `sessions.el`), `Persona`
+  (`soul.el:250-292`), plus identity/value `Knowledge` nodes.
+
+The types the MCP surface names — `Self`, `BacklogItem`, `SessionSummary`,
+`Artifact`, `Process`, `ConfigEntry` — are **`node_type` string conventions set
+by higher neuron/Axon layers**, not runtime-known types. Where `BacklogItem` /
+`Artifact` are set was not in the files read (they route to the Axon backend, doc
+02) — **flag as unverified/TODO** for a human pass.
+
+## Edges
+
+`EngramEdge` — `el_runtime.c:6701-6730+`. Directed, typed, weighted:
+
+| Field | Meaning |
+|---|---|
+| `id`, `from_id`, `to_id`, `relation` | typed relation string |
+| `weight` (double) | **authored** strength — never mutated by activation |
+| `hebb` (double) | **learned** co-activation potentiation — the fraction of recent activations in which both endpoints were in working memory together; strictly separate from `weight` |
+| `inhibitory` (int flag) | if set, activating the source **suppresses** the target's WM weight instead of exciting it |
+| `confidence`, `created_at`, `updated_at`, `last_fired`, `layer` | — |
+
+The **`hebb` field is the co-activation weight** — the Hebbian/LTP channel — kept
+deliberately separate from the static authored `weight`. Edges are created via
+`engram_connect(from, to, weight, relation)` (`server.el:253`).
+
+**Relation strings observed:** `associates` (default, `server.el:248`),
+`identity`, `co-value`, `birthday-twin`, `canonical-self` (`soul.el:37-108`),
+`supersedes`, `tombstones`, `contains`, `tagged` (`neuron-api.el`,
+`el_runtime.c:6168`).
+
+## Consciousness layers
+
+Orthogonal to memory tiers, the engram has five canonical **layers**
+(`el_runtime.c:5919-5924`):
+
+| id | Name | activation_priority | Role |
+|---|---|---|---|
+| 0 | SAFETY | 0 (fires earliest) | deepest / limbic |
+| 1 | CORE_IDENTITY | — | **default** for all nodes (`ENGRAM_LAYER_DEFAULT`, `:7423`) |
+| 2 | DOMAIN | — | domain knowledge |
+| 3 | IMPRINT | — | persona overlay |
+| 4 | SUIT | — | outermost |
+
+`EngramLayer` (`:6731-6738`) carries `activation_priority` (lower fires first),
+`suppressible` (can higher layers suppress it?), `transparent` (invisible to
+introspection?), and `injectable` (add/remove at runtime?). Layers are managed
+via `engram_add_layer` / `engram_node_layered` / `engram_list_layers`. This is
+the identity-vs-domain-knowledge stratification, independent of the tier system
+below.
+
+## Two tier systems — do not conflate them
+
+This is the single most important clarification in the data model, and the source
+of the vocabulary mismatch flagged throughout this set.
+
+### A. Cognitive memory tiers — the `tier` field
+`Working` / `Episodic` / `Semantic` / `Procedural` (and `Canonical` in use).
+Runtime default `"Working"` (`el_runtime.c:7408`; `README.md:41-49`). Nodes
+**migrate between these by salience decay/reinforcement**, driven by the runtime.
+Salience decays as `importance × 1/(1 + days_since) × ln(count + 1)`
+(`README.md:57-62`). `memory.el` exposes `tier_working`/`episodic`/`canonical`
+helpers (`memory.el:1-3`); `soul.el` writes `Semantic`-tier persona nodes
+(`:267`, `:282`). So the live tier set is **{Working, Episodic, Semantic,
+Procedural, Canonical}** with continuous salience/importance/confidence floats.
+
+### B. Epistemic tiers & disposition — tags, not runtime concepts
+The MCP-facing vocabulary — tiers `note → lesson → canonical`, disposition
+`experimental → provisional → stable → deprecated` — is **not enforced anywhere
+in `el_runtime.c`.** It is stored as **tags**:
+
+- Knowledge capture preserves the incoming epistemic tier as a `tier:<x>` tag
+  rather than mapping onto a cognitive tier — deliberately, to avoid a lossy
+  mapping (`server.el:519-522, 544`).
+- `promote_knowledge` writes a canonical node tagged
+  `["Knowledge","tier:canonical","disposition:stable"]` (`neuron-api.el:533`).
+
+There is **no state machine** validating `experimental → … → deprecated`.
+Disposition and epistemic tier are convention-by-tag. *(Flag: not structurally
+guarded. The exact MCP-enum → tag/float mapping is not fully traced in the files
+read — unverified/TODO.)*
+
+## Write-protection
+
+`is_protected_node(id)` (`neuron-api.el:20-37`) is a **hard-coded allowlist of 15
+identity/value node IDs** — the self root, the values hub, intellectual-dna,
+memory-philosophy, voice, and the 8 value nodes. Handlers that could mutate the
+graph (tombstone / supersede / evolve / connect) check it and return HTTP 403
+`api_err_protected` (`:39-41`) for a protected target (checked at `:384, 511,
+692, 705, 746, 768`). Edges *into* a protected node are also blocked
+(`handle_api_link_entities`).
+
+**The one sanctioned override** is `POST /api/neuron/cultivate`
+(`neuron-api.el:781-816`) — it performs the same ops with the protection check
+skipped, gated by convention to Will's explicit cultivation sessions. The self
+layer is writable, but only through a deliberate door.
+
+## Immutability — tombstone, never delete
+
+Engram nodes are immutable (`memory.el:64-69`). The model is:
+
+- **Tombstone** — `mem_tombstone(node_id)` (`memory.el:46-71`) **keeps the node
+  and all its edges**, creates a `Tombstone` marker node
+  (`content = target id`, `label = "tombstone:<id>"`) and wires a `tombstones`
+  edge (weight 1.0). It never calls `engram_forget`. This is *the* one canonical
+  delete — every user-facing forget path routes through it. Default bounded reads
+  hide tombstoned nodes (`memory_hide_tombstoned`, `neuron-api.el:239-249`);
+  `?include_deleted=1` recovers them.
+- **Supersede** — updates/evolves (`neuron-api.el:394-428, 506-541, 715-734`)
+  create a **new** node with the new content, wire a `supersedes` edge new→old
+  (weight 0.9, or 0.95 for promote), and **keep the original**. The response
+  returns both ids so the caller re-points. This is the `supersedes_id`
+  pattern: new node linked, old preserved, full audit trail.
+
+> **The hole to know about.** The raw runtime `engram_forget` **does** hard-delete
+> (frees node + edges, `el_runtime.c:7647`), and the engram HTTP route
+> `DELETE /api/nodes/:id` calls it directly (`server.el:322-328`). Immutability
+> is therefore an invariant of the **neuron-api / MCP layer routing**, not of the
+> store. A client that hits engram HTTP directly can bypass it. *(flag)*
+
+`engram_forget` is also used *internally* for genuine GC: boot-counter pruning
+(`memory.el:184`), session-summary/telemetry pruning (`soul.el:369`,
+`sessions.el`). Those are bounded housekeeping, not user deletes.
+
+## Persistence, snapshots, backups
+
+- **Storage:** a single JSON snapshot `snapshot.json` under `ENGRAM_DATA_DIR`,
+  written by `engram_save` / read by `engram_load` (`el_runtime.c:9660+`; format
+  `{"nodes":[...],"edges":[...]}`). In prod that dir is the RWO PVC mount `/data`
+  (doc 04).
+- **Write policy:** `persist_canonical()` writes the **full** snapshot after every
+  durable write (`server.el:133-141`). The batch-edge route snapshots **once per
+  batch** to avoid ~150 GB/day of writes from Hebbian edge churn
+  (`server.el:258-305`) — this is why `hebb_consolidate` batches (doc 02).
+- **Boot safety:** on load, engram writes `snapshot.boot-backup.json` (good load)
+  or `snapshot.failed-load.json` (a non-empty file that parsed to 0 nodes)
+  (`server.el:718-734`). Read routes export to scratch paths
+  (`.scan-export.json`, `.sync-export.json`) and **never** touch the canonical
+  (`server.el:207-223, 418-437`) — a guard added after a read-route corrupted the
+  snapshot.
+- **Off-cluster backup:** a Kubernetes CronJob (`engram-backup`) tars `/data`
+  every 15 minutes to `gs://neuron-db-backup/gke/neuron-prod/` and keeps the last
+  96 (24h) (`infrastructure/platform/k8s/neuron-mcp/backup-cronjob.yaml`).
+- **Retention:** InternalStateEvent telemetry pruned at 48h
+  (`ENGRAM_ISE_RETENTION_MS`, `server.el:485-499`).
+
+> **Data-dir mismatch to flag:** the `server.el` header comment says the default
+> is `~/.neuron/engram` (`:16`) but the code defaults to `/tmp/engram`
+> (`:135, 717`). Prod overrides both via `ENGRAM_DATA_DIR=/data`. *(unverified —
+> which default is intended)*
+
+## The engram HTTP surface (`:8742`)
+
+Dispatcher `handle_request` (`server.el:592-707`). Auth: `ENGRAM_API_KEY`; GETs
+always allowed, mutations require `"_auth":"<key>"` in the JSON body
+(`server.el:578-588`).
+
+| Endpoint | Purpose |
+|---|---|
+| `GET /health`, `GET /` | health + live node/edge counts |
+| `POST /api/nodes`, `GET /api/nodes`, `GET /api/nodes/:id`, `DELETE /api/nodes/:id` | node CRUD (DELETE = hard `engram_forget`) |
+| `GET /api/edges`, `POST /api/edges`, `POST /api/edges/batch`, `GET /api/neighbors/:id?depth` | edge ops + traversal |
+| `POST\|GET /api/activate?q&depth`, `POST\|GET /api/search` | spreading activation vs lexical search |
+| `POST /api/strengthen` | Hebbian potentiation |
+| `POST /api/save`, `/api/load`, `/api/load-merge` | snapshot control |
+| `GET /api/sync` | soul daemon periodic pull |
+| `GET /api/embed-backfill`, `GET /api/similarity?a&b` | embeddings + cosine |
+| `POST /api/neuron/state-events` (auth-exempt), `POST /api/neuron/knowledge/capture` | neuron-layer helpers |
+| `GET /api/stats`, `/api/act-stats`, `/api/text-health` | telemetry |
+
+## Retrieval model (summary)
+
+Retrieval is **spreading activation, not query matching**:
+`strength = parent_strength × edge_weight × target_salience ×
+cosine(query, target)` — multiplicative, top-N, with the two-layer
+background → working-memory promotion (`README.md:27-36`; `el_runtime.c:5892+,
+6094+`). `mem_recall` / `/api/activate` fire this and mutate WM; `mem_search` /
+`/api/search` are passive lexical scans. The cognitive API's `begin_session` and
+`compile_ctx` return a **bounded projection** of the activated set, never the raw
+graph (doc 02, §2).

+
+## Process & port topology
+
+A running neuron is **two processes in one container**: the soul and the engram,
+started by `entrypoint.sh`.
+
+```
+ container (one pod)
+ ┌──────────────────────────────────────────────────────────┐

+ └──────────────────────────────────────────────────────────┘
+```
+
+- `entrypoint.sh` starts engram with `ENGRAM_BIND=:8742` and
+  `ENGRAM_DATA_DIR=/data`, polls `http://localhost:8742/health` (up to 60s;
+  Autopilot cold starts are slow), then `exec`s the soul. `SOUL_ENGRAM_PATH` is
+  deliberately unset so `ENGRAM_URL` triggers **HTTP mode** (soul talks to engram
+  over localhost HTTP, not an in-process embed).
+- EL HTTP runtime is tuned down for co-located calls: `EL_HTTP_TIMEOUT_MS=10000`,
+  `EL_HTTP_CONNECT_TIMEOUT_MS=3000` (`entrypoint.sh`).
+
+### Full port map
+
+| Port | Process | Role | Source |
+|---|---|---|---|
+| 7779 | mcp-proxy | MCP client entry; byte-forward + retry | `mcp-proxy/src/main.el` |
+| 17779 | mcp-wrapper | MCP JSON-RPC ⇄ soul REST; tool catalog | `mcp-wrapper/src/main.el` |
+| 7770 | soul | HTTP cognitive API + `handle_request` | `NEURON_PORT`, `deployment-blue.yaml` |
+| 8742 | engram | graph store HTTP | `entrypoint.sh`, `server.el:711` |
+| 7771 | neuron-connectd | MCP connector bridges | `routes.el` `connectd_*` |
+
+**Local vs prod, an important distinction.** The proxy → wrapper chain is the
+**local developer adapter**: a stdio MCP client (Claude Code) needs to reach an
+HTTP soul, so the proxy/wrapper translate and add resilience. In **production**,
+the `neuron-mcp` Kubernetes Service is a ClusterIP that targets the soul's
+`:7770` directly (`service.yaml`) — external access is "to be wired via
+Cloudflare Tunnel later" (annotation, same file). So in prod the MCP/HTTP
+boundary is the soul's own HTTP surface; the proxy/wrapper are not (yet) in the
+cluster path. *(inference from the ClusterIP-only Service + the local-only
+proxy/wrapper binaries.)*
+
+## The MCP request path (end to end)

+
+Responsibilities per hop, and the volatility each isolates (VBD reading):
+
+1. **proxy** — transport resilience. Isolates *client connection volatility*
+   (drops, retries, health) from everything above. No MCP semantics.
+2. **wrapper** — protocol translation. Isolates the *MCP protocol* from the soul:
+   owns `initialize`/`tools/list`/`tools/call`, the ~90-tool catalog, and
+   `dispatch_tool_call`. Also fires the `fire_activation` `/recall` side effect so
+   tool use warms working memory.
+3. **soul** — cognition. `handle_request` dispatch → `handle_api_*` → engram
+   builtins. In HTTP mode it reaches engram over localhost; otherwise embedded.
+4. **engram** — the graph. Spreading activation, Hebbian edges, snapshot
+   persistence.
+
+For the user-facing chat pipeline (not tool calls), `/api/chat` enters
+`layered_cycle` (soul.el) — L1 safety → L2 stewardship → L3 imprint — described
+in `02-components.md §3c`.
+
+## Production: GKE blue/green
+
+Neuron prod runs on GKE cluster **`neuron-platform`** (Autopilot, us-central1),
+namespace **`neuron-prod`**. Two Deployments, `neuron-mcp-blue` and
+`neuron-mcp-green`, share one Service selector that names the *active slot*.
+
+- **Deployments** (`deployment-blue.yaml` / `deployment-green.yaml`): one
+  container `soul`, image pinned by **digest** (not `:latest`) so Argo CD can't
+  drift the active slot to an untested build (see the pin comment in
+  `deployment-blue.yaml`). `strategy: Recreate` — the PVC is RWO so only one pod
+  can hold it at a time. Probes hit `/health` on `:7770`.
+- **Service** (`service.yaml`): ClusterIP `neuron-mcp`, port 7770 → 7770,
+  `selector: {app: neuron-mcp, slot: blue}`. The blue/green script patches
+  `slot`.
+- **Storage** (`pvc.yaml`): `neuron-engram-data`, `standard-rwo` (pd-balanced),
+  10Gi, RWO. Engram data is the single `snapshot.json` (~8MB active).
+- **The swap** (`scripts/blue-green-deploy.sh`): (1) set image on the target
+  slot; (2) scale target to 1, wait for rollout; (3) **patch the Service selector
+  to the new slot** (traffic flip); (4) scale the old slot to 0. Imperative
+  `kubectl` for the live swap, then git-update the Argo manifests so a sync
+  doesn't revert replica counts.
+- **Backup** (`backup-cronjob.yaml`): every 15 min, tar `/data` → GCS, keep 96.
+
+### Resource sizing (learned the hard way)
+
+`deployment-blue.yaml` documents the memory history in comments: idle soul RSS
+~860Mi; the `beginSession` call (loads memories + backlog + preferences) spikes
+past 1Gi and OOM-killed the pod mid-request (client socket closed). Current
+setting: `requests = limits = 2Gi`, cpu 250m/1000m. This is *why* the cognitive
+API projects/compacts payloads so aggressively (doc 02 §2, doc 01 axis 1) — the
+memory ceiling is real and close.
+
+## CI/CD
+
+Two Gitea Actions workflows (`.gitea/workflows/`), serialized on a single GCE
+runner (`concurrency: neuron-runner`).
+
+- **`ci.yaml`** (push/PR to `main`):
+  - **build:** free disk → checkout → install gcc/libcurl/gcloud → download
+    `el-runtime-c`/`el-runtime-h` from Artifact Registry `foundation-prod`
+    (`elc`/`elb` intentionally **not** downloaded) → compile the committed
+    `dist/soul.c` directly: `cc -O2 -DHAVE_CURL dist/soul.c el_runtime.c -lssl
+    -lcrypto -lcurl -lpthread -lm -o dist/neuron` → `strip -s` → smoke test
+    `dist/neuron --help` → publish `neuron-soul@<sha8>` to AR (push only).
+  - **deploy** (push-to-main only): auth GCP → `get-credentials neuron-platform`
+    → **determine idle slot** (the deployment at 0 replicas) → prepare artifacts
+    (soul binary + `elc` + runtime for the Docker build) → **clone the engram
+    repo** into `./engram/` (Dockerfile builds engram from source) → `docker
+    build`+push `neuron-soul:<sha>` → `scripts/blue-green-deploy.sh --image
+    --slot` → git-push updated infra manifests → `kubectl rollout status` →
+    verify `neuron-mcp` endpoints.
+- **`deploy-gke.yaml`** (`workflow_dispatch` only, slot default `green`) — manual
+  rollback / forced-slot deploy without a rebuild; same auth → slot → docker →
+  blue-green → manifest-sync → verify steps.
+
+The Docker image (`Dockerfile`) is a two-stage build: stage 1 compiles
+`engram/src/server.el` → `engram.c` → `engram` binary via `elc` + `cc`; stage 2
+is an Ubuntu 24.04 runtime (GLIBC 2.39 satisfies both binaries) with `soul` +
+`engram` + `entrypoint.sh`.
+
+## Config & secrets (high level)
+
+Runtime configuration is injected as environment, sourced from a Kubernetes
+Secret `neuron-soul-secrets` via ExternalSecret (ESO → GCP Secret Manager,
+Workload Identity — no key files). From `deployment-blue.yaml`:
+
+| Env | Meaning |

+# Neuron — El & the Build Pipeline
+
+> The soul and the engram are written in **El**, a self-hosted language that
+> compiles to C11. This document covers the language layer, the
+> amalgamation → `soul.c` → binary pipeline, how the soul is composed from its
+> layers, and the compile-time capability gates. Sources: `manifest.el`,
+> `soul.el`, `dist/soul.c`, the El toolchain under `foundation/el/`
+> (`elc.c`, `elb.el`, `BOOTSTRAP.md`), and `.gitea/workflows/`.
+
+## The El language layer
+
+El is a compiled, Lisp-family language transpiled to C11. Every El program links
+a shared runtime, `el_runtime.c` / `el_runtime.h`, which implements **all
+builtins**: the engram graph engine (`engram_*`), HTTP (`http_*`), JSON
+(`json_*`), crypto, time, LLM calls, and DHARMA primitives (`el_runtime.h`,
+`BOOTSTRAP.md:599-644`). The runtime also provides an arena allocator (server
+mode) and ARC refcounting. Practically: **the runtime is both the standard
+library and the database** — the graph physically lives in `el_runtime.c`, and El
+source files are the orchestration/logic on top.
+
+A recurring texture in the source is workaround comments for codegen quirks
+(e.g. broken `%`/`*` operators). These are El-compiler maturity issues, not
+architecture — but they explain some of the hand-rolled arithmetic in
+`awareness.el`/`memory.el`.
+
+## The toolchain: `elc`, `elb`, `el_runtime`
+
+| Tool | What it is | Role |
+|---|---|---|
+| `elc` | the El compiler, **self-hosted** (written in El) | compiles one El translation unit → C11. Import resolution is textual, depth-first, dedup'd — it inlines all imports into one string and emits forward decls for every fn (`BOOTSTRAP.md:927-936`). |
+| `elb` | the build coordinator (`elb.el`, ~367 lines) | reads `manifest.el`, walks the import graph, does **incremental** separate compilation using `.elh` header files (`extern fn` decls), links the final binary (".NET-style incremental build", `BOOTSTRAP.md:886, 916-925`). |
+| `el_runtime.c/.h` | the C runtime | linked by every compiled El binary; implements all builtins and the graph engine. |
+
+The `.elh` files present in this repo (`soul.elh`, `memory.elh`,
+`neuron-api.elh`, `routes.elh`, …) are **auto-generated headers** (`elc
+--emit-header`) — the `extern fn` interface each module exports. They are the
+contract surface `elb` uses for incremental builds, and they double as a concise
+map of each module's public functions.
+
+### Self-hosting fixed point
+
+`elc` is bootstrapped from a seed binary (`dist/platform/elc`, Mach-O arm64) and
+verified by a **fixed-point self-recompile**: the compiler must compile its own
+source to a byte-identical binary (`BOOTSTRAP.md:7-58, 801-816`). Pipeline:
+`elc-cli.el → compiler.el → lexer/parser/codegen.el`.
+
+## Building the soul: `.el → elc → .c → cc → binary`
+
+The concrete pipeline (mirrored in the engram build, `engram/src/server.el:8-11`):
+
+```
+   soul.el (+ imports)
+        │  elc  (self-hosted El→C11, inlines imports)
+        ▼
+   dist/soul.c   (~31,300 lines — single amalgamated translation unit)
+        │  cc -std=c11 -O2  soul.c  el_runtime.c
+        ▼
+   dist/neuron   (native binary)
+```
+
+### Why `dist/soul.c` is committed
+
+`dist/soul.c` is the authoritative combined translation unit, **regenerated on
+macOS by running `elb`**. It is checked into the repo on purpose: CI compiles it
+**directly** and skips `elb` entirely (`ci.yaml`). The reason is operational, not
+aesthetic —
+
+- `elb` succeeds on arm64/macOS `ld`, but **fails on Linux** (duplicate strong
+  symbols), and
+- `elc` uses 24GB+ virtual memory, which **OOM-kills the 16GB CI runner**.
+
+So the pattern is: **compile on the Mac, commit the amalgamation, and let Linux
+CI do only the cheap `cc` step.** `dist/` also holds the per-module `.c` outputs
+(`memory.c`, `awareness.c`, `chat.c`, the NLG morphology tables, …) —
+intermediate artifacts of the same process.
+
+> **Mechanism note (observed during the self-load regen).** The single-TU
+> `dist/soul.c` is produced by running `elc` over the **flattened import set** —
+> every module source in `soul.el`'s transitive import graph, concatenated with
+> `import` lines stripped, compiled in one pass (`elc` hoists forward decls for
+> all functions, so concat order doesn't affect correctness). `elb` on its own
+> emits **per-module `.c` + a linked binary**, not the combined `soul.c`; it is
+> the separate-compilation coordinator, and `elc soul.el` alone yields only the
+> soul module. Because the amalgamation is regenerated only on demand, it can lag
+> the `.el` sources: this PR regenerated it after it had fallen behind several
+> source commits, and folded in the `inspect_graph` relevance-ranked projection
+> (the `compact=1` self-load fix, doc 02) so CI ships it.
+
+## How the soul is composed (layer stack)
+
+`manifest.el` declares the build:
+
+```
+package "neuron" { version "0.1.0"  edition "2026" }
+build { entry "soul.el" }
+```
+
+The comment in `manifest.el:8-16` documents the intended **layer composition
+order**: a base layer `../foundation/nlg` (the NLG engine — 31-language
+morphology, grammar, realizer, semantics) with the **soul layer** (`soul.el`)
+injected on top. New layers are added by importing them in `soul.el` before the
+soul's own code. *(The `../foundation/nlg` path is the manifest's stated NLG base;
+the NLG sources compile into the `dist/*.c` morphology/grammar tables seen in the
+tree.)*
+
+`soul.el` itself imports, in order (`soul.el:1-10`): `elp.el`, `memory.el`,
+`safety.el`, `stewardship.el`, `imprint.el`, `awareness.el`, `chat.el`,
+`studio.el`, `elp-input.el`, `routes.el` — then declares the `cgi "neuron-soul"`
+identity block (`:12-17`): `dharma_id`, `principal`, `network`, and
+`engram: http://localhost:8742`. Because `elc` inlines imports depth-first, this
+import list *is* the amalgamation order that produces `dist/soul.c`.
+
+The `cgi` block is not just metadata — it sets the program's **capability tier**
+(next section).
+
+## Compile-time capability gates
+
+El's codegen classifies each program by its top-level declaration and **enforces
+capabilities at compile time** (`BOOTSTRAP.md:958-965`):
+
+| Declaration | Tier | Allowed |
+|---|---|---|
+| `cgi { … }` | full | everything — `llm_call_agentic`, `llm_register_tool`, `dharma_emit`, `dharma_field`, LLM, DHARMA |
+| `service { … }` | restricted | no `llm_call_agentic` / `llm_register_tool` / `dharma_emit` / `dharma_field` |
+| neither | utility | no DHARMA, no LLM |
+
+A program that calls a capability its tier forbids **fails to compile**: codegen
+emits a C `#error` naming the forbidding call, so the downstream `cc` aborts.
+This is the **primary hard gate** in the build — capability escalation is caught
+by the compiler, not at runtime. The soul is a `cgi`, so it gets the full tier;
+`engram` is declared without `cgi`/`service` semantics that would grant LLM
+access (it is a store).
+
+## Verification gates
+
+| Gate | Where | What it checks |
+|---|---|---|
+| Capability tier | El codegen (`BOOTSTRAP.md:958`) | no capability escalation; hard `#error` at compile |
+| Self-hosting fixed point | `elc` bootstrap (`BOOTSTRAP.md:801`) | compiler reproduces itself byte-identically |
+| `test_soul_guard.el` | `tests/` | the genesis `safe_to_seed` boot guard — a sparse/oversized snapshot must not clobber the graph |
+| `test_layer_contract.el` | `tests/` | JSON interface shapes between composition-stack layers that `layered_cycle` depends on (e.g. `safety_screen` always returns an `action` field) |
+| other `tests/*.el` | `tests/` | `test_sessions.el`, `test_safety.el`, `test_bell_safety.el`, `test_layered_cycle.el`, `test_imprint.el`, `test_stewardship.el`, `test_api_define_process.el`, … |
+| CI smoke test | `ci.yaml` | `dist/neuron --help` runs |
+
+> **Flag (unverified/TODO).** CI (`ci.yaml`) runs only the `cc` compile + the
+> `dist/neuron --help` smoke test — it does **not** invoke the `tests/*.el`
+> soul-guard / layer-contract suites, and `.githooks/` is empty. Whether these
+> tests are gated anywhere (a pre-merge hook, a separate workflow, or manual
+> discipline on the Mac before regenerating `soul.c`) is **not evident in the
+> files read**. This is the most important build-integrity gap to confirm with a
+> human: the contract tests exist but their enforcement point is unproven.
+
+## Practical consequences for a contributor
+
+- **You cannot rebuild the whole soul on Linux/CI.** Regenerate `dist/soul.c` on
+  a Mac (`elb`), commit it, then CI compiles it. Changing an `.el` file without
+  regenerating `soul.c` ships nothing.
+- **The `.elh` files are your API map.** To see what a module exposes, read its
+  `.elh` — it's the generated `extern fn` list.
+- **Memory/activation behavior often can't be changed from this repo.** The
+  volatile numeric core is in `foundation/el` `el_runtime.c`. Doc 01, Divergence
+  6 explains why this is the sharpest edge in the architecture.
+- **The engram is a separate repo.** It is cloned and compiled by CI
+  (`Dockerfile`, `.gitea/workflows/`), not vendored here. Its source of truth is
+  `foundation/el/engram`.
