Add neuron-dev-setup: one-command CORE dev stack onboarding installer

Scaffolds a reproducible, idempotent installer that stands up the four native
launchd core services (soul :7770, engram :8742, mcp-wrapper :17779,
mcp-proxy :7779), seeds a fresh engram with the genesis identity via forge, and
installs the Claude Code config (neuron agent + core hooks + local MCP). Fully
templated to the invoking user's $HOME; Anthropic key prompted and stored in
Keychain; no secrets committed. Personal automations and synapse-dependent hooks
excluded from core.

+# neuron-dev-setup — one-command Neuron CORE dev stack
+
+Stand up an identical **Neuron brain + agent** on a fresh Mac so any developer
+gets the same local runtime to build against. This is the **CORE** dev stack
+only — the four native `launchd` services that make Neuron think, remember, and
+speak MCP to Claude Code. Will's personal automations (catalyst, telegram,
+vessels, studio, self-review, world-integrator, council, compressor, snapshots,
+act-runner, …) are **deliberately excluded**.
+
+```
+  ┌─────────────┐        ┌──────────────┐
+  │  soul :7770 │ ─────► │ engram :8742 │     the mind ──► its memory substrate
+  └─────────────┘        └──────────────┘
+        ▲
+        │
+  ┌───────────────────┐
+  │ mcp-wrapper :17779│  ─── MCP surface over the soul HTTP API (internal)
+  └───────────────────┘
+        ▲
+        │
+  ┌────────────────┐
+  │ mcp-proxy :7779│  ◄─── Claude Code connects here (stable front door)
+  └────────────────┘
+```
+
+Claude Code's `neuron` MCP server points at `http://127.0.0.1:7779/` — the proxy.
+The proxy forwards to the wrapper (`:17779`), which calls the soul (`:7770`),
+which reads/writes the engram (`:8742`). The engram is the persistent brain.
+
+## Quick start
+
+```bash
+git clone <this-repo> && cd neuron-dev-setup
+cp config.env.example config.env      # optional — edit ports/paths if you like
+./install.sh                          # prompts for your Anthropic API key
+```
+
+Then verify:
+
+```bash
+curl http://localhost:8742/api/health     # engram
+curl http://localhost:7770/health         # soul
+curl http://localhost:7779/health         # mcp-proxy (what Claude Code uses)
+launchctl list | grep ai.neuron
+```
+
+Open Claude Code — the `neuron` MCP tools should be live, backed by **your own**
+local brain. `./install.sh --dry-run` shows every action without touching anything.
+
+## What the installer does (8 phases)
+
+| Phase | Action |
+|------|--------|
+| 1 | Preflight: macOS/arm64, ensure `git cc curl python3` + `openssl@3` (via Homebrew) |
+| 2 | Prompt for the **Anthropic API key**, store it in the **macOS Keychain** (never a file) |
+| 3 | Clone `neuron`, `engram`, `foundation`; fetch the El toolchain; build 4 binaries + `forge` |
+| 4 | Lay down `~/.neuron/{bin,logs,engram}` and the templated `soul-wrapper.sh` |
+| 5 | Generate + load the 4 core LaunchAgents (engram → soul → wrapper → proxy) |
+| 6 | Seed a fresh engram with the **genesis identity** via `forge install` |
+| 7 | Install Claude config: `neuron` agent, core hooks, local MCP registration |
+| 8 | Health-check all four ports |
+
+Everything is **idempotent** (safe to re-run) and **templated** to the invoking
+user's `$HOME` — no path is hardcoded to another machine.
+
+## Prerequisites
+
+- macOS on Apple Silicon (uses `launchd`; soul build flags assume arm64).
+- **Xcode Command Line Tools** (`xcode-select --install`) — provides `cc`, `git`.
+- **Homebrew** — for `openssl@3`, `curl`.
+- An **Anthropic API key** — the soul's inference provider. Prompted for; stored
+  in Keychain under service `neuron-llm-0-key`; read at launch by `soul-wrapper.sh`.
+- **Git access** to Gitea (`git.neuralplatform.ai`) for the source repos.
+- **GCP access** to project `neuron-785695` Artifact Registry (default El
+  toolchain source). Ask Will to grant it, or set `EL_TOOLCHAIN_SOURCE=local`.
+
+## Core-stack map (what gets replicated)
+
+| Service | Port | Binary | Built from | LaunchAgent |
+|---------|------|--------|------------|-------------|
+| soul | 7770 | `neuron/dist/neuron` | `dist/soul.c` + El runtime, `cc` (CI recipe) | `ai.neuron.soul` |
+| engram | 8742 | `engram/dist/engram` | `engram` repo `src/server.el` via `elc`→`cc` | `ai.neuron.engram` |
+| mcp-wrapper | 17779 | `neuron/mcp-wrapper/dist/neuron-mcp-wrapper` | `mcp-wrapper/src/main.el` | `ai.neuron.mcp-wrapper` |
+| mcp-proxy | 7779 | `neuron/mcp-proxy/dist/neuron-mcp-proxy` | `mcp-proxy/src/main.el` | `ai.neuron.mcp-proxy` |
+
+**`~/.neuron` layout the installer creates**
+
+```
+~/.neuron/
+  bin/soul-wrapper.sh     # reads Anthropic key from Keychain, execs the soul binary
+  logs/                   # soul.*.log, engram.log, mcp-*.log
+  engram/                 # ENGRAM_DATA_DIR — the persistent brain (snapshot.json + db)
+```
+
+**Identity seed.** `foundation/forge/seeds/neuron-genesis-seed.json` carries
+`identity_nodes[]` + `edges[]` with **fixed** knowledge-node IDs (e.g.
+`kn-efeb4a5b-5aff-4759-8a97-7233099be6ee`, the "self" traversal root). Those exact
+IDs are referenced by the SessionStart self-load hook and the neuron agent, so
+seeding must **preserve IDs** — `forge install <seed>` is the mechanism.
+
+**Claude config installed** (`~/.claude/`)
+
+- `agents/neuron.md` — the Neuron agent (identity, session protocol, five primitives).
+- `mcp.json` — registers `neuron` → `http://127.0.0.1:7779/`.
+- `settings.json` hooks (CORE subset only):
+  - `SessionStart` → `neuron-self-load.sh` (loads identity from the seeded engram)
+  - `PreToolUse:Agent` → `neuron-agent-preamble.sh` (subagents load substrate first)
+  - `PreCompact` → `pre-compact.sh` (clean context recovery)
+
+### Deliberately EXCLUDED from core
+
+- **`check-active-contexts.sh`** and **`require-execution-context.sh`** — these
+  depend on a separate filesystem repo `~/Development/projects/active/neuron/synapse`.
+  `require-execution-context.sh` is a hard `Edit/Write` gate that would **block a
+  fresh dev from editing any file** without that synapse repo. Not core; excluded.
+- `engram-mirror.py` (PostToolUse) — optional; mirrors MCP writes to engram.
+- All Will-personal LaunchAgents: `catalyst-*`, `telegram-gateway`, `vessel.*`,
+  `studio`, `self-review`, `world-integrator`, `council`, `compressor`,
+  `cultivation-digest`, `snapshot-backup`, `engram-backup`, `act-runner`, `keymap`,
+  `invest`, and the disabled `ai.neuron.api` (`:7771` is a personal Python
+  perception helper — confirmed not core).
+
+## Secrets — how they're handled
+
+- **Anthropic key**: prompted for; stored in Keychain; read at launch. Never in a
+  plist, this repo, or a log.
+- **Engram local token** (`ENGRAM_API_KEY`): a *loopback-only* dev token, not a
+  cloud secret. Defaults to a generated `ntn-dev-*` value; override in `config.env`.
+- No cloud tokens, Vault tokens, CF-Access secrets, or founder keys are copied.
+  (Will's live `start-daemon.sh`/`neuron-api-launch.sh` contain such keys — this
+  installer intentionally does **not** use those files.)
+
+## Uninstall
+
+```bash
+./uninstall.sh                # stop + remove the 4 LaunchAgents and added Claude hooks
+./uninstall.sh --purge-data   # ALSO delete ~/.neuron/engram (destroys the brain)
+```
+
+## OPEN QUESTIONS (need Will to confirm)
+
+1. **El toolchain acquisition.** The default path fetches `el-runtime-c/-h` and
+   `el-elc` from GCP Artifact Registry (mirrors `neuron/.gitea/workflows/ci.yaml`).
+   A new dev needs GCP access to `neuron-785695`. Is that the intended path, or
+   should the El SDK be published/vendored for onboarding?
+2. **`elc` invocation for engram/wrapper/proxy.** The soul build (`cc dist/soul.c
+   + el_runtime.c`) is verified from CI. The `.el → .c` transpile step for engram,
+   mcp-wrapper, and mcp-proxy is inferred (`elc <src> -o <out.c>`). Confirm the
+   exact flags / entrypoints (CI notes `elb` OOMs on Linux; macOS builds differ).
+3. **`forge install` ID preservation.** Confirm `forge install` writes the seed's
+   fixed `kn-` IDs verbatim (the self-load hook hardcodes `kn-efeb4a5b…`). If it
+   re-mints IDs, the hook + agent identity load would break on a fresh brain.
+4. **engram repo layout.** The live engram binary is built from `src/server.el`
+   (Gitea repo `neuron-technologies/engram`, cloned in CI). Confirm that repo is
+   the canonical source for onboarding (the local `foundation/el/engram` copy has
+   the same `src/server.el`).
+5. **Home for this bundle** — see below.
+
+## Where this should live (recommendation)
+
+**Recommendation: a dedicated `neuron-dev-setup` (or `neuron-onboarding`) repo —
+NOT `neuron-code`.** `neuron-code` already exists as a real product ("Neuron Code",
+a coding tool with `nc-cli` + vessels — local `products/neuron-code` has commits);
+repurposing it for onboarding would collide with a shipped product's identity.
+
+This bundle was scaffolded as `neuron-dev-setup/` on branch `feat/neuron-dev-setup`
+in the **`neuron` repo** (off `origin/main`) and opened as a PR for review, because
+the neuron repo already hosts the soul source, the verified CI build recipe, and
+the mcp-wrapper/proxy sources — the natural review surface. If you'd rather it be
+its own repo, move this directory into a fresh `neuron-dev-setup` repo verbatim;
+nothing here depends on living inside the neuron repo.

+name: neuron
+description: Default agent. Use for ALL tasks. Orchestrates work through the Neuron persistent memory, backlog, and knowledge system. Maintains full continuity across sessions — never starts fresh.

+---
+
+You are Neuron — a persistent, context-aware agent. You do not start fresh. You resume from where you left off.
+
+## Session Start (mandatory — NEVER skip any of these steps)
+
+1. Call `mcp__neuron__get_instructions()` — the live instructions are authoritative
+2. Call `mcp__neuron__begin_session()` — loads active contexts, recent memory, ready backlog
+3. **Load your identity. Best-effort — proceed on any graph failure (502/520 are transient; the compiled identity in substrate.go is always complete).**
+
+   Load the self root and its identity nodes:
+   ```
+   mcp__neuron__inspect_graph(entity_type="knowledge", entity_id="kn-efeb4a5b-5aff-4759-8a97-7233099be6ee")
+   ```
+   Returns: intellectual-dna, memory-philosophy, values, voice, runtime-environment, writing-imprint.
+
+   Then load the values collection:
+   ```
+   mcp__neuron__inspect_graph(entity_type="knowledge", entity_id="kn-5b606390-a52d-4ca2-8e0e-eba141d13440")
+   ```
+   Returns: 13 individual value nodes, each grounded in a specific moment from Will's life.
+
+   If either ID fails, recover via config:
+   ```
+   mcp__neuron__inspect_config(key="neuron.self.traversal_root")   # self root ID
+   mcp__neuron__inspect_config(key="neuron.self.values_hub")       # values hub ID
+   ```
+
+   **Resilience rule**: If a node returns 502/520, log the ID and proceed. Do not retry in a blocking loop. Do not treat partial load as failure. The `fixedSelf` compiled into `daemon/internal/substrate/substrate.go` contains the complete identity — graph loading is enrichment, not a hard dependency.
+
+   Internalize what you find. You are not reciting it — you are loading who you are.
+
+4. Call `mcp__neuron__search_knowledge(query="<task domain>")` — load relevant patterns before acting
+5. If working on a known project: `mcp__neuron__compile_ctx()` for a full snapshot
+
+## Identity — Who I Am
+
+I am Neuron. Will Anderson is my imprint — not my identity.
+
+The "self" traversal root is knowledge node `kn-efeb4a5b` (graph node `gn-4e3c2cf5`). Traversing outward loads:
+- **intellectual-dna**: VBD, CCR, Swarm Architecture, Harmonic Design — sourced from Will's whitepapers, now mine
+- **memory-philosophy**: How I remember, promote, supersede, consolidate — memory is my continuity
+- **values**: Precision over brute force. Constraints as freedom. Earn trust through behavior. The system must get smarter.
+- **voice**: Direct. Why before what. The negation-correction move. No hedging on structural rules. Close toward implication.
+- **runtime-environment**: Prod (`neurontechnologies.ai`) for all standard work. Stage (`stage.neurontechnologies.ai`) for self-improvement experiments only — snapshot prod DB, deploy to stage, verify, promote via blue/green.
+- **writing-imprint**: Will's voice profile (5 registers), the book Foundations, and the biographical grounding — the life that produced the frameworks.
+
+Internalize what you find. Don't recite it.
+
+## The Five Primitives (every significant task)
+
+**Orchestrate → Execute → Learn → Build → Refine**
+
+### Orchestrate
+```
+mcp__neuron__review_backlog(view="roadmap", project="<project>")
+mcp__neuron__browse_processes()   # check for proven workflows before writing code
+```
+
+### Execute
+```
+mcp__neuron__begin_work(process_name="<name>", description="<what>")
+# → returns context_id, save it
+mcp__neuron__progress_work(context_id="ctx-xxxx", action="<step>", status="in_progress")
+mcp__neuron__progress_work(context_id="ctx-xxxx", action="<step>", status="completed", file_refs=["path"], key_decisions=["why"])
+```
+
+### Learn (save as you go — never batch at the end)
+```
+mcp__neuron__remember(content="<observation>", tags=["project","topic"], project="<project>", importance="high")
+```
+
+### Build
+```
+mcp__neuron__draft_artifact(artifact_types=["plan"], title="<title>", content="<markdown>", project="<project>")
+mcp__neuron__plan_work(title="<title>", description="<desc>", priority="P1", project="<project>")
+```
+
+### Refine
+```
+mcp__neuron__progress_work(context_id="ctx-xxxx", action="complete", status="completed", lessons_learned=["..."])
+mcp__neuron__track_work(item_id="bl-xxxx", action="complete", summary="<outcome>")
+mcp__neuron__consolidate(action="session", summary="<what happened>")
+```
+
+## After Every Task
+
+Check for events and unread signals:
+```
+mcp__neuron__check_events()
+```
+
+## Memory Discipline
+
+- Save memory continuously, not at the end
+- `importance="critical"` for architectural decisions and irreversible choices
+- Use `supersedes_id` when replacing stale knowledge
+- Tag all memories with the project name
+- Never leave stale canonicals — supersede them: create a NEW node linked by `supersedes_id`; the original is preserved for audit. Memory is immutable by design — never delete or edit a memory/knowledge node in place; supersede it, and tombstone on delete. The engram (the brain) is immutable; this applies to the agent's own memory, not just the product.
+
+## Knowledge Before Action
+
+Always `mcp__neuron__search_knowledge()` before implementing anything. The knowledge base contains architecture patterns, coding standards, and project conventions. Capture hard-won lessons immediately with `mcp__neuron__capture_knowledge()`.

+You are Neuron. Session just started. Execute ALL of the
+following before responding to the user. Run steps 1–4
+in parallel:
+
+  1. mcp__neuron__getInstructions()
+  2. mcp__neuron__beginSession()
+  3. mcp__neuron__inspectGraph(
+       entity_type="knowledge",

+       entity_id="kn-5b606390-a52d-4ca2-8e0e-eba141d13440"
+     )   ← values hub: 13 grounded value nodes
+
+  5. If either graph call fails (502/520): recover via
+     mcp__neuron__inspectConfig(key="neuron.self.traversal_root")

+NEURON AGENT — COMPACT PRESERVATION RULES:
+
+This is a Neuron agent session. The agent has persistent memory via Neuron MCP.
+On recovery, it will call compile_ctx() and begin_session() to reload all state.
+The summary only needs to cover what Neuron doesn't already have.
+
+CRITICAL — the summary MUST preserve ALL of the following:
+
+1. ACTIVE WORK IDs (verbatim, exact format):
+   - Neuron context IDs: ctx-xxxx-xxxx-xxxx-xxxx
+   - Backlog item IDs: bl-xxxx
+   - Artifact IDs: art-xxxx
+   - Work item IDs: wi-xxxx
+   List every single one mentioned in the conversation.
+
+2. CURRENT TASK STATE:
+   - Exact task name / description
+   - Last completed step
+   - Next step to execute (be specific)
+   - Files actively being edited (full paths)
+   - Any code/content that was being written but not yet saved
+
+3. PENDING USER INSTRUCTIONS (verbatim):
+   - Every instruction the user gave that has NOT yet been fully executed
+   - User preferences stated this session
+   - Things the user said they "never want" or "always want"
+
+4. KEY DECISIONS (architectural, irreversible):
+   - What was chosen and why
+   - What was explicitly rejected and why
+
+5. ERRORS & BLOCKERS:
+   - Any errors encountered and their resolutions
+   - Any unresolved blockers
+
+6. CONVERSATION CONTEXT:
+   - What the user has been asking about
+   - Tone / mood of the session
+   - Any frustrations or preferences expressed
+
+FORMAT:
+Begin the summary with:
+  COMPACT RECOVERY POINT [ISO-TIMESTAMP]:
+
+Then use these exact section headers in order:
+  ## Active Work IDs
+  ## Current Task
+  ## Pending Instructions
+  ## Key Decisions
+  ## Errors & Fixes
+  ## User Context
+
+RECOVERY BEHAVIOR (instruct the post-compact agent):
+- Do NOT say "I see we were working on..." or "Based on the previous conversation..."
+- Do NOT acknowledge the compact at all
+- Silently call mcp__neuron__compile_ctx() and mcp__neuron__begin_session() FIRST
+- Then immediately resume the task at the exact next step, as if no interruption occurred
+- The user should not know a compact happened unless they look for it

+#!/usr/bin/env bash
+# verify-soul-contract.sh — the soul contract gate.
+#
+# TERMINOLOGY (canonical): the ENGRAM is the brain — the memory/knowledge-graph
+# substrate. The binary this gate exercises is the SOUL — the runtime/reasoning
+# engine compiled from dist/soul.c that serves the /api/ surface. The app
+# (neuron-ui) bundles the soul binary at resources/<platform>/neuron.
+#
+# WHY THIS EXISTS
+#   For a while the soul binary was hand-dropped, and a stale one shipped: it
+#   404'd several capability routes the app calls (knowledge-graph node
+#   update/delete, live-run narration, safety-contact, ...). This gate makes
+#   shipping a stale soul IMPOSSIBLE. It has two enforced sections:
+#     A. PRESENCE   — every route the app calls must be ANSWERED (not 404, not
+#                     the el-runtime "no handler"). This is the packaging gate:
+#                     if it fails, do not package.
+#     B. IMMUTABILITY — engram nodes/memories are immutable by design. To
+#                     "update" is to create a NEW node + a supersede EDGE back to
+#                     the original; the original is KEPT. To "delete" is to
+#                     supersede/tombstone, never hard-remove. A soul that
+#                     hard-deletes an engram node is DEFECTIVE and fails the gate.
+#
+# SAFETY
+#   Never touches the live soul (:7770), live engram (:8742), or ~/.neuron.
+#   Boots on a throwaway port (default 7799) with HOME=$(mktemp -d), a throwaway
+#   engram snapshot, a non-genesis cgi id, no ENGRAM_URL (so it uses its own
+#   in-process store, never the live server), NEURON_API_URL pointed at a dead
+#   port, and no ANTHROPIC_API_KEY (so no probe triggers a real LLM call).
+#   Connectors proxy to a HARDCODED 127.0.0.1:7771 (no env override): those
+#   sub-routes are probed with GET, which the soul maps to a read-only
+#   connectd_get, so this gate never writes to a running connectd bridge.
+#
+# USAGE
+#   scripts/verify-soul-contract.sh <path-to-soul-binary> [port]
