From 799ca3758bc5ac2b59375a9eccbb714a03df4979 Mon Sep 17 00:00:00 2001 From: Tim Lingo Date: Mon, 8 Jun 2026 16:14:20 -0500 Subject: [PATCH 01/10] Fix chat.el node_type-slot bug + add engram write-corruption handoff MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit chat.el recorded the soul's utterance via engram_node(content, "episodic", ...), putting a TIER into the node_type slot (nodes showed node_type="episodic"). Now uses engram_node_full(..., "Conversation", "soul:utterance", ..., "Episodic", tags). The core wrapper fix is in the el repo (PR #52). HANDOFF-engram-write-corruption.md has the full root-cause analysis, coercion mechanism, caller audit, validation, deploy runbook (elc build + restart), and the data-prune proposal (~107 corrupt nodes, all unrecoverable genesis/binary detritus → prune; backup taken).

Because `el_val_t` is an untyped machine word, the compiler coerced caller args to the wrong declared types and forwarded them **by position** into a C function whose positions mean different things → `tier` got ints, `importance/confidence` got strings, `label` got a float, etc. One caller (`chat.el`) also put a *tier* into the `node_type` slot. + +Source fixes are done. **You need to:** review, build with `elc`, restart the soul, verify, and apply the prune (daemon stopped).

So `chat.el engram_compile` always hits its "no embeddings" fallback (chat.el line 25-27) and the model sees ~2 nodes. **Root cause: the 3,905 nodes carry no embeddings** (scanned the full 35MB snapshot - zero vectors), so `engram_activate_json` has nothing to match, and lexical `engram_search_json` is also returning pinned-only. Tim's own GraphRAG eval measured it: live search 1.7% P@5 vs offline BM25 55%. **Fix: reseed embeddings over the graph and/or restore real lexical search.** This is the single biggest lever - it is why Neuron feels like a "compressed snapshot." + +### Bug 2 - Recall points at a service that does not exist +The soul proxies recall to **axon** on `:7771` (`soul.el:179`, default `http://localhost:7771`, used via `axon_get`/`axon_post` in `routes.el`). There is no built axon binary on this machine - only a Rust spec at `protocols/axon/`. Meanwhile engram runs on `:8742`. So `/api/memories/recall` always fails with a :7771 connection error. **Fix: ship/run axon, or repoint recall at engram :8742.** + +### Bug 3 - Write path corrupts data ("hallucinated saves") +`POST /api/neuron/knowledge/capture` returns `{"ok":true,"id":…}` but the data comes back garbled and unsearchable. Test: I captured `"cli-write-test- marker"`; read-back returned a node whose content was the literal query string `q=cli-write-test…&limit=2`, `node_type:"2"`, a binary label, and tier `"limit="`.

Treat this as a +proposal: it is scaffolding that works around current soul limitations, and most of it +should be retired once the soul does these things natively. + +## The model + +"Neuron in the CLI" = Claude Code operating **as** Neuron: the soul/graph provide identity +and memory, Claude Code provides reasoning and agency (real tools, plus writing memories +back). Posting to the soul's non-agentic `/api/chat` gives the "light version" (Sonnet, +plus the retrieval problems below), so this approach puts the reasoning in Claude Code and +reads/writes the graph directly. + +## Files + +- **`CLAUDE.md.example`** - the operating identity. Placed at a session's working-dir root + (e.g. `~/CLAUDE.md`), it makes Claude Code load Neuron's identity from the graph + (intellectual-DNA / values / memory-philosophy), hold the voice rules, and run the + recall/remember loop. Example contains Tim-specific context; genericize before reuse. +- **`neuron_recall.py "" [n]`** - READ path. BM25 over + `~/.neuron/engram/snapshot.json` plus local CLI memories.

Earlier approach, kept for reference. +- **`neuron_mcp.py`** - stdlib MCP server exposing `neuron_chat`, `neuron_search_knowledge`, + `neuron_search_memory` to Claude Code, with graceful degradation when the soul's memory + recall backend is down. +- **`HANDOFF.md`** - full writeup of what was set up and the soul-side bugs to fix + (retrieval/embeddings, the missing axon :7771 service, the write path, daemon engram + supervision, and voice). + +## What should replace this + +When the soul does native semantic retrieval, persists captures correctly, and exposes a +real identity/voice surface for the CLI, these scripts become unnecessary.

Each stub documents the layer contract it must satisfy when replaced. - Fix GET /api/chat bypass: update the GET branch in handle_request to call layered_cycle() consistently with the POST branch, rather than calling handle_chat() directly and skipping the consciousness stack. - Export layered_cycle() from soul.elh (and dist/soul.elh) so routes.el can resolve the symbol via the header import. - Fix steward_action else branch: add explicit handling for "block" (returns safe refusal immediately, skips L3) and "redirect" (uses redirect_to field). Unknown actions now log a warning and fall back to the screened input rather than silently passing an empty string to imprint_respond(). - Document hard_bell path: clarify that omitting auto_persist/history update is intentional security isolation, and document the safety_validate second-param sentinel contract ("hard_bell" vs screen_action). --- dist/soul.elh | 1 + imprint.el | 29 +++++++++++++++++++++++++++++ imprint.elh | 3 +++ routes.el | 18 +++++++++++++++++- safety.el | 33 +++++++++++++++++++++++++++++++++ safety.elh | 4 ++++ soul.el | 34 ++++++++++++++++++++++++++++++++-- soul.elh | 1 + stewardship.el | 15 +++++++++++++++ stewardship.elh | 2 ++ 10 files changed, 137 insertions(+), 3 deletions(-) create mode 100644 imprint.el create mode 100644 imprint.elh create mode 100644 safety.el create mode 100644 safety.elh create mode 100644 stewardship.el create mode 100644 stewardship.elh diff --git a/dist/soul.elh b/dist/soul.elh index ae5e5a4..290dff3 100644 --- a/dist/soul.elh +++ b/dist/soul.elh @@ -2,3 +2,4 @@ extern fn init_soul_edges() -> Void extern fn load_identity_context() -> Void extern fn emit_session_start_event() -> Void +extern fn layered_cycle(raw_input: String) -> String diff --git a/imprint.el b/imprint.el new file mode 100644 index 0000000..7baeea7 --- /dev/null +++ b/imprint.el @@ -0,0 +1,29 @@ +// imprint.el — L3 Imprint layer (stub — full implementation in feat/layer-imprint) +// Routes the processed input through the active imprint and generates the final reply. +// This stub allows soul.el and routes.el to compile while feat/layer-imprint is pending merge. +// +// Contract for imprint_current() -> String: +// Returns the active imprint ID (node ID from engram), or "none" if no imprint is loaded. +// Used in health checks and to identify which imprint L2/L3 should operate against. +// +// Contract for imprint_respond(input, imprint_id) -> String: +// Generates a reply from the active imprint given the stewardship-aligned input. +// Falls back to handle_chat when no imprint is active (imprint_id = "" or "none"). + +fn imprint_current() -> String { + let contextual: String = state_get("active_contextual_imprint") + if !str_eq(contextual, "") { + return contextual + } + let user_imp: String = state_get("active_user_imprint") + if !str_eq(user_imp, "") { + return user_imp + } + return "none" +} + +fn imprint_respond(input: String, imprint_id: String) -> String { + // Stub: delegate to core chat until feat/layer-imprint is merged + let body: String = "{\"message\":\"" + json_safe(input) + "\"}" + return handle_chat(body) +} diff --git a/imprint.elh b/imprint.elh new file mode 100644 index 0000000..79d84f5 --- /dev/null +++ b/imprint.elh @@ -0,0 +1,3 @@ +// auto-generated by elc --emit-header — do not edit +extern fn imprint_current() -> String +extern fn imprint_respond(input: String, imprint_id: String) -> String diff --git a/routes.el b/routes.el index 849811c..ad808e5 100644 --- a/routes.el +++ b/routes.el @@ -4,6 +4,7 @@ import "chat.el" import "studio.el" import "elp-input.el" import "neuron-api.el" +import "soul.elh" fn strip_query(path: String) -> String { let q: Int = str_index_of(path, "?") @@ -234,7 +235,22 @@ fn handle_request(method: String, path: String, body: String) -> String { return if str_eq(edges_raw, "") { "[]" } else { edges_raw } } if str_eq(clean, "/api/chat") { - return handle_chat(body) + // GET /api/chat: pass through layered_cycle for consistency with POST path. + // GET chat is a legacy probe interface; body may be empty for simple pings. + let raw_msg: String = json_get(body, "message") + let eff_msg: String = if str_eq(raw_msg, "") { body } else { raw_msg } + if str_eq(eff_msg, "") { + return "{\"error\":\"message required\"}" + } + let agentic_flag: Bool = json_get_bool(body, "agentic") + let reply: String = if agentic_flag { + handle_chat_agentic(body) + } else { + let screened_reply: String = layered_cycle(eff_msg) + screened_reply + } + auto_persist(body, reply) + return reply } if str_eq(clean, "/api/conversations") { return handle_conversations(method) diff --git a/safety.el b/safety.el new file mode 100644 index 0000000..88247f0 --- /dev/null +++ b/safety.el @@ -0,0 +1,33 @@ +// safety.el — L1 Safety layer (stub — full implementation in feat/layer-safety) +// Provides safety screening and validation for the consciousness stack. +// This stub allows soul.el to compile while feat/layer-safety is pending merge. +// +// Contract for safety_screen(input, history) -> String (JSON): +// {"action": "pass" | "hard_bell", "content": "", "reason": ""} +// +// Contract for safety_validate(output, screen_action) -> String: +// Second param is the original screen_action ("pass") or the sentinel "hard_bell". +// Returns the validated output string, or a safe refusal if validation fails. +// +// Contract for safety_log_bell(severity, reason, excerpt) -> Void: +// Logs a bell event to engram. severity = "hard" | "soft".

Is there an index file that's missing/stale? +Fixing this restores recall everywhere at once. **This is the real fix.** + +### Option 2 — Pragmatic EL-level fallback (no native changes) +Since `engram_scan_nodes_json()` works, `engram_compile` could do a keyword scan when the +vector path is empty: pull nodes, substring/token match the query against `content` + +`label`, rank by overlap, return the top N. Restores basic recall even with the vector +index down. ~20 lines of EL in `engram_compile`, but requires a soul rebuild + restart. +Claude offered to write this patch for your review if you want it — say the word. + +Tradeoff: keyword matching is much weaker than semantic recall (won't find "jokes" unless +the node text literally contains joke-ish words), but it's strictly better than the current +two-node fallback and needs no native/runtime work. + +--- + +## Also needs attention + +- **Soul daemon (:7770) was down** at end of session — restart and confirm it stays up. +- **Confirm the engram instance topology** — :8742 standalone shows 0 nodes while the + soul's in-process engram has the data. Make sure chat is reading the populated one and + they haven't diverged. +- **Social memory weighting** (Tim's deeper point): even once retrieval works, jokes / + interpersonal moments may not be tagged or salience-weighted to surface as "important." + Worth a look at how those get captured and scored — but that's secondary to getting + retrieval working at all. + +--- + +## Daemon lifecycle — needs a supervisor (NEW, 2026-06-06) + +The soul daemon **crashed again** the next day. It had been up earlier, then died on its +own (not from any change). When it's down, the UI's Backlog / Artifacts / Knowledge / +Graph / Memories tabs all go **blank**, because they read from `:7770/api/graph/nodes`. +The chat also stops working. This is the second unexplained death in two days. + +### How it's currently run (fragile) +- Binary: `neuron/dist/neuron-fresh` (compiled from the EL sources) +- Launched manually as a bare background process (`./neuron-fresh &`) — **no supervisor, + no auto-restart, no crash logging beyond stdout**. When it dies, it stays dead until a + human notices the blank UI and restarts it. +- Boot log only shows `[http] listening on [::]:7770` — there's no captured stack/exit + reason when it crashes, so we can't yet say *why* it's dying. + +### How I restarted it (for reference) +```sh +# snapshot lives at ~/.neuron/engram/snapshot.json (loaded on boot, ~9.7MB) +# ALWAYS back it up first — genesis boot re-saves it: +cp ~/.neuron/engram/snapshot.json ~/.neuron/engram/snapshot.backup-$(date +%Y%m%d-%H%M%S).json + +cd neuron/dist +ANTHROPIC_API_KEY='' NEURON_PORT=7770 ./neuron-fresh > /tmp/soul-restart.log 2>&1 & +# verify: +curl -s http://127.0.0.1:7770/health +# → {"status":"alive","cgi_id":"ntn-genesis","boot":2,"node_count":3660,"edge_count":14207,...} +``` +After this, data came back: 3,660 nodes / 14,207 edges; Backlog 485, Memory 493, etc. + +### Recommendations for Will +1. **Put it under a supervisor** so it auto-restarts on crash and logs exit codes: + - macOS dev: a `launchd` LaunchAgent plist (KeepAlive=true), or `brew services`, or + even a simple `while true; do ./neuron-fresh; done` wrapper with timestamped logs. + - Prod/k8s already has `entrypoint.sh` + restart policy — the gap is the **local dev** + run path. +2. **Capture crash diagnostics** — redirect stdout/stderr to a rotating logfile and, if the + EL runtime can, dump a reason on exit. Right now we're blind to the cause. +3. **Find the root cause of the crashes** — two self-deaths in two days suggests a real bug + (memory? an unhandled request? a panic in a native builtin?). The supervisor stops the + *symptom* (blank UI) but not the underlying instability. +4. **Snapshot safety** — genesis boot calls `engram_save(snapshot)` (soul.el:240,248). A + crash mid-save could corrupt the 9.7MB memory file. Consider write-to-temp + atomic + rename, and/or periodic timestamped backups, so a bad save can't lose Neuron's memory. + +--- + +## What was NOT touched +No backend EL code and no engram data were modified — the memory-recall diagnosis is +read-only. The only operational action taken was **restarting the already-existing +`neuron-fresh` daemon** (after backing up the snapshot) to bring the blank UI tabs back; +no source or data was changed by that. All UI work this session was in `neuron-ui` and is +unrelated to this bug. diff --git a/chat.el b/chat.el index 935d893..fc5829b 100644 --- a/chat.el +++ b/chat.el @@ -270,6 +270,70 @@ fn agentic_tools_with_web() -> String { return "[" + inner + ",{\"type\":\"web_search_20250305\",\"name\":\"web_search\",\"max_uses\":5}]" } +// --------------------------------------------------------------------------- +// MCP connectors.
