fix: address review feedback (星月)

1. trySendSync: wrap child.send in try/catch — IPC race between connected check and send
2. gracefulStop: same try/catch for shutdown send
3. Remove crashTimestamps reset on ready — crash window detection was being bypassed

+# Nerve Coding Conventions
+
+## Core Concepts
+
+```
+External World → Sense → Signal → Reflex → Workflow → Log
+                  ↑                                     ↑
+              "what to observe"                  "what to do"
+```
+
+**Nerve** is a lightweight observation engine daemon for autonomous agents. It continuously observes external state, reacts to changes via declarative rules, and orchestrates multi-step workflows.
+
+### Key Terms
+
+| Concept | What it is |
+|---------|-----------|
+| **Sense** | A `compute()` function that samples or derives data. Returns `T \| null` — non-null emits a Signal, null is silent. Each Sense has its own SQLite database. |
+| **Signal** | A notification emitted when a Sense returns non-null. Pure fact, no intent. Distributed via an in-memory Signal Bus. Not persisted. |
+| **Reflex** | A declarative trigger (YAML) connecting Senses to actions. Trigger types: `interval` (periodic), `on` (react to Signals). Action types: trigger a Sense, or start a Workflow. |
+| **Workflow** | A stateful multi-step execution. Contains **Roles** (actors with side effects) and a **Moderator** (pure router). Each instance is a **Thread** with a unique `runId`. |
+| **Log** | Immutable audit trail. Records executions, state transitions, errors. **Cannot trigger Reflexes** — prevents feedback loops. |
+| **Engine** | The kernel orchestrating everything. Holds Signal Bus, Reflex Scheduler, Process Manager, Workflow Manager. Never loads user code directly — all user code runs in isolated Workers. |
+| **Daemon** | The `nerve-daemon` package — engine runtime. Runs as a background process. |
+
+### Architecture Rules
+
+- **Three orthogonal extension points**: Sense (what to compute), Reflex (when to compute), Workflow (what to do)
+- **Process isolation**: One worker per Sense group (long-lived), one per Workflow type (on-demand). Workers never talk to each other.
+- **Causality is one-directional**: External world → Sense → Signal → Reflex → Action + Log. Logs are the end of the chain.
+
+
+
+## Language & Paradigm
+
+### Functional-first
+
+Use `function` + `type`, not `class` + `interface`.
+
+```typescript
+// ✅ Good
+type Signal = {
+  senseId: string;
+  value: unknown;
+  ts: number;
+};
+
+function createSignal(senseId: string, value: unknown): Signal {
+  return { senseId, value, ts: Date.now() };
+}
+
+// ❌ Bad — no class, no interface
+class Signal implements ISignal { ... }
+```
+
+### Rules
+
+| Rule | Description |
+|------|-------------|
+| `type` over `interface` | All type definitions use `type` |
+| `function` over `class` | Pure functions + closures, no class |
+| No `this` | Functions must not depend on `this` context |
+| No inheritance | No `extends`, `implements`, `abstract` |
+| Composition over inheritance | Use function composition |
+| Immutability first | Use `Readonly<T>`, `as const`, avoid mutation |
+| No optional properties | Use `T \| null` instead of `?:` — see below |
+
+### Exceptions
+
+Classes are allowed when:
+- Required by a third-party library (e.g. Drizzle's `sqliteTable`)
+- Error subclasses (`class NerveError extends Error`)
+
+### No Optional Properties
+
+Never use `?:`. All nullable fields must be explicit `T | null`.
+
+```typescript
+// ✅ Good
+type SenseConfig = {
+  group: string;
+  throttle: string | null;
+  timeout: string | null;
+};
+
+// ❌ Bad
+type SenseConfig = {
+  group: string;
+  throttle?: string;
+  timeout?: string;
+};
+```
+
+For mutually exclusive fields, use discriminated unions:
+
+```typescript
+// ✅ Good
+type ReflexConfig =
+  | { kind: "sense"; sense: string; interval: string | null; on: string[] | null }
+  | { kind: "workflow"; workflow: string; on: string[] | null };
+```
+
+## Modules & Exports
+
+- Always named exports, never default exports
+- One module = one responsibility, filename = purpose
+
+```typescript
+// ✅ Named exports only
+export function startEngine(config: EngineConfig): Engine { ... }
+export type EngineConfig = { ... };
+
+// ❌ No default exports
+export default function startEngine() { ... }
+```
+
+## Naming
+
+| Type | Style | Example |
+|------|-------|---------|
+| Files | kebab-case | `signal-bus.ts` |
+| Types | PascalCase | `SignalBus` |
+| Functions/variables | camelCase | `createSignalBus` |
+| Constants | UPPER_SNAKE | `MAX_RETRY_COUNT` |
+| Generics | Single letter or descriptive | `T`, `TValue` |
+
+## Error Handling
+
+- Use `Result` type for expected failures
+- `throw` only for unrecoverable bugs (programmer errors)
+- No try-catch for flow control
+
+```typescript
+type Result<T, E = Error> = { ok: true; value: T } | { ok: false; error: E };
+
+function parseSenseConfig(raw: unknown): Result<SenseConfig> { ... }
+```
+
+## Async
+
+- Always `async/await`, never `.then()` chains
+
+## Toolchain
+
+| Tool | Purpose |
+|------|---------|
+| **pnpm** | Package manager |
+| **TypeScript** | Type checking (strict mode) |
+| **Biome** | Lint + format (replaces ESLint + Prettier) |
+| **tsup** | Bundling |
+
+### Commands
+
+```bash
+pnpm run check      # biome check (lint + format)
+pnpm run format     # biome format --write
+pnpm run build      # full build
+pnpm test           # run tests
+```
+
+## Monorepo Structure
+
+```
+nerve/
+  packages/
+    core/           # @nerve/core — shared types and utils

+# No Dynamic Import in Production Code
+
+## Rule
+
+Do NOT use `await import()` or dynamic `import()` expressions in production source code.
+Always use static top-level `import` statements.
+
+## Why
+
+- Static imports enable tree-shaking and bundler optimizations
+- They make dependencies explicit and discoverable at a glance
+- Dynamic imports of Node built-ins or project modules add unnecessary async overhead
+
+## Exceptions (must include a comment explaining why)
+
+1. **`sense-runtime.ts`** — loads user-authored sense modules whose paths are only known at runtime
+2. **`workflow-worker.ts`** — loads user-authored workflow modules whose paths are only known at runtime
+
+When suppressing, add a comment directly above:
+
+```ts
+// Dynamic import required: user module path resolved at runtime
+const mod = await import(senseIndexPath);
+```
+
+## Test Files
+
+Test files (`__tests__/**`) are exempt — dynamic import after `vi.mock()` is standard vitest practice.

+# Adapter Process Isolation
+
+Describes sandboxing, process isolation, resource limits, and timeout enforcement for adapter invocations in the Nerve workflow system.
+
+## Process Isolation Model
+
+Adapters run in a **two-tier isolation** model:
+
+1. **Workflow Worker Process** — Each workflow runs in a dedicated Node.js worker process (`workflow-worker.ts`) forked from the main daemon
+2. **Adapter Child Process** — Each adapter spawns CLI tools as child processes via `spawnSafe()` with `shell: false`
+
+## Resource Limits & Timeouts
+
+### Adapter-Level Timeouts
+
+- **Default timeout**: 300 seconds (300,000ms) for both cursor and hermes adapters
+- **Configurable** via `AgentConfig.timeout` in adapter factory functions
+- **Wall-clock enforcement** using `setTimeout()` — kills child process with `SIGTERM` on timeout
+- **AbortSignal support** — external cancellation triggers immediate `SIGTERM`
+
+### Timeout Behavior
+
+```ts
+// Timeout resolution priority (packages/core/src/spawn-safe.ts):
+// 1. Explicit timeoutMs value
+// 2. AbortSignal presence → no internal timer (relies on external abort)
+// 3. DEFAULT_TIMEOUT_MS (300_000) fallback
+```
+
+- Child process terminated with `SIGTERM` on timeout/abort
+- Returns `{ kind: "timeout", stdout, stderr }` error result
+- **No grace period** — immediate kill
+- **No SIGKILL escalation** — relies entirely on `SIGTERM` effectiveness
+
+#### SIGTERM Limitations
+
+If a child process **ignores or blocks `SIGTERM`** (e.g., signal handlers, blocked delivery):
+
+- **No fallback to `SIGKILL`** — process may remain alive indefinitely
+- **No escalation timer** — spawnSafe() does not implement progressive signal escalation
+- **Potential zombie/orphan risk** — unresponsive processes continue consuming resources
+- **OS-level cleanup only** — relies on parent process death or OS reaping mechanisms
+
+## Sandboxing Characteristics
+
+### What's Isolated
+
+- **File system**: Child process runs in specified `cwd` (workflow working directory)
+- **Environment**: Controlled env vars via `nerveCommandEnv()` + optional overrides
+- **Network**: No explicit restrictions (inherits parent process network access)
+- **Process tree**: Child processes are direct children, not containerized
+
+### What's NOT Sandboxed
+
+- **No resource quotas** (CPU, memory, disk I/O limits)
+- **No filesystem chroot/containers** — full filesystem access within user permissions
+- **No network isolation** — can make arbitrary network calls
+- **No syscall filtering** — no seccomp or similar restrictions
+
+#### Runtime Resource Enforcement
+
+**No active resource monitoring or constraints**:
+
+- **No cgroups** (Linux) — no CPU, memory, or I/O limits enforced
+- **No job objects** (Windows) — no resource quotas or process tree limits
+- **No worker_threads resource tracking** — Node.js worker processes run unrestricted
+- **Pure timeout-based enforcement** — only wall-clock time limits via `setTimeout()`
+- **OS-scheduled resource sharing** — relies entirely on operating system process scheduling
+
+Adapters can consume unlimited:
+- **CPU time** (until timeout)
+- **Memory** (until OOM)
+- **Disk I/O** (no quotas)
+- **Network bandwidth** (no throttling)
+- **File descriptors** (until ulimit)
+
+#### Environment Variable Security
+
+The `nerveCommandEnv()` function provides **minimal sanitization**:
+
+```ts
+// spawn-safe.ts lines 47-55
+export function nerveCommandEnv(): SpawnEnv {
+  const home = homedir();
+  const pnpmHome = join(home, ".local/share/pnpm");
+  return {
+    ...process.env,           // ← Full parent environment inherited
+    PNPM_HOME: pnpmHome,
+    PATH: `${pnpmHome}:${process.env.PATH ?? ""}`,
+  };
+}
+```
+
+- **No filtering of sensitive keys** — `NODE_OPTIONS`, `LD_PRELOAD`, `PYTHONPATH` passed through unchanged
+- **Full environment inheritance** — all parent process environment variables copied
+- **Injection risk** — malicious env vars (e.g., `NODE_OPTIONS=--require=evil.js`) affect Node.js child processes
+- **Path manipulation** — sensitive PATH entries remain accessible to adapters
+
+## Security Model
+
+### Execution Context
+
+- Uses `shell: false` to prevent shell injection attacks
+- Arguments passed as separate array elements (not shell-parsed)
+- PATH includes `~/.local/share/pnpm` for tool discovery
+- Inherits parent process user/group permissions
+
+#### File Descriptor Management
+
+```ts
+// spawn-safe.ts line 122
+stdio: ["ignore", "pipe", "pipe"]
+```
+
+- **stdin closed**: Child receives no input (`stdio[0]: "ignore"`)
+- **stdout/stderr captured**: Piped to parent for collection (`stdio[1,2]: "pipe"`)
+- **No explicit fd closing**: Node.js default behavior — inherits other file descriptors
+- **Parent sockets/pipes accessible**: Child can access parent's open network connections, database handles, etc.
+- **Security risk**: Adapter processes may access unintended parent file descriptors
+
+### Attack Surface
+
+- CLI tools have **full user-level filesystem access**
+- Can spawn additional processes (not tracked/limited)
+- Network requests unrestricted
+- Resource consumption relies on OS-level limits
+
+## Worker Process Management
+
+### Workflow Isolation
+
+- Each workflow type gets dedicated worker process
+- Worker processes handle multiple concurrent threads (runIds)
+- Kill flags enable per-thread cancellation without killing worker
+- Graceful shutdown waits up to 10 seconds for in-flight operations
+
+#### Cross-RunId Contamination Risks
+
+**Shared mutable state** poses contamination risks between concurrent runIds:
+
+- **`process.env` mutations**: Environment changes affect all subsequent runIds in same worker
+- **`require.cache` pollution**: Module cache shared across all runIds — side effects persist
+- **Global variables**: Any global state mutations from one runId visible to others
+- **`process.cwd()` changes**: Working directory changes affect entire worker process
+- **File descriptors**: Open files/sockets shared between runId executions
+
+**No runId-specific scoping** implemented:
+- Worker reuses single Node.js process for efficiency
+- Each role execution sees cumulative environment from previous runIds
+- **Mitigation relies on adapter discipline** — clean implementations avoid global mutations
+
+### Error Handling
+
+- Adapter failures don't crash the worker process
+- Timeout/abort errors are isolated to specific role execution
+- Worker process survives adapter failures and continues serving other threads
+
+## Configuration
+
+```yaml
+# Example nerve.yaml configuration for timeout overrides
+workflows:
+  my-workflow:
+    roles:
+      coder:
+        adapter:
+          type: cursor
+          timeout: 600000  # 10 minutes in milliseconds
+```
+
+Timeout configuration happens at the adapter creation level, not as a system-wide sandbox policy.

+# Agent Adapters (RFC-003)
+
+Adapter = capability. Role = scenario. Workflows declare adapters directly via import.
+
+## AgentFn Protocol
+
+```ts
+type AgentFn = (ctx: ThreadContext, systemPrompt: string) => Promise<string>
+```
+
+- Input: thread context (`{ threadId, start, steps }`) + system prompt (role identity)
+- Output: **single-shot `Promise<string>`** — no streaming support
+- Adapter handles tool-specific details internally
+
+### Streaming Limitations
+
+The `AgentFn` protocol does **not** support streaming responses (`AsyncIterable<string>` or `ReadableStream`). It's strictly limited to single-shot `Promise<string>` returns.
+
+For long-running or incremental agent outputs:
+- CLI tools buffer full output until completion
+- Timeout enforcement via `timeoutMs` (default 300s)
+- No intermediate results exposed to workflow logic
+- Progress indication happens at the CLI tool level only
+
+## Available Adapters
+
+| Package | Adapter | Tool |
+|---------|---------|------|
+| `@uncaged/nerve-adapter-cursor` | `cursorAdapter` / `createCursorAdapter()` | cursor-agent CLI |
+| `@uncaged/nerve-adapter-hermes` | `hermesAdapter` / `createHermesAdapter()` | hermes chat CLI |
+
+Each exports a **default instance** (sensible defaults) and a **factory** for custom config.
+
+## Usage in Workflows
+
+Adapters are passed directly to `createRole`:
+
+```ts
+import { createRole } from "@uncaged/nerve-workflow-utils";
+import { cursorAdapter } from "@uncaged/nerve-adapter-cursor";
+
+const coder = createRole(cursorAdapter, prompt, schema, extractConfig);
+```
+
+No registry, no config indirection. TypeScript catches missing adapters at compile time.
+
+## Extract Layer
+
+Parses agent raw string → typed meta. Configured in `nerve.yaml`:
+
+```yaml
+extract:
+  provider: dashscope
+  model: qwen-plus
+```
+
+Two-level merge: global → role override. Retry once on parse failure (feeds error back to LLM), then throw `ExtractError`.
+
+## Error Handling
+
+When adapters' underlying CLI tools (e.g., `cursor-agent` or `hermes`) fail, errors are surfaced **synchronously via rejection** with no fallback/retry logic:
+
+- **Missing/unavailable tool**: `spawn_failed` error when CLI binary not found in `$PATH`
+- **Non-zero exit code**: `non_zero_exit` error with captured stdout/stderr
+- **Timeout**: `timeout` error when execution exceeds configured `timeoutMs`
+- **Abort signal**: `aborted` error when `AbortSignal` triggers cancellation
+
+All errors are immediately thrown as `Error` instances with descriptive messages (e.g., `"cursor-agent: exitCode=7 stdout=... stderr=..."`). No automatic retries or fallback adapters.

+# Nerve Architecture
+
+Observation engine for autonomous agents — sense the world, react to changes, run workflows.
+
+## Core Pipeline
+
+```
+External World → Sense → Signal → Workflow → Log
+                           ↑
+                     compute() returns
+                     { signal, workflow }
+```
+
+Causality is **one-directional**. Logs are the end of the chain — they cannot trigger further Senses (prevents feedback loops).
+
+## Two Extension Points
+
+| Extension | Question | Nature |
+|-----------|----------|--------|
+| **Sense** | What to observe & when to react | `compute()` pure function + YAML config (interval / on) |
+| **Workflow** | What to do | Roles + Moderator |
+
+Senses own both the "what" (compute logic) and the "when" (config-driven scheduling). A Sense can trigger a Workflow directly by returning `{ signal, workflow: { name, prompt } }`.
+
+## Two Event Types
+
+- **Signal** — from Sense compute (non-null return). Pure fact, no intent. Drives the front half (perception).
+- **Command Event** — inside Workflow Threads. Has causal chain, must be responded to. Drives the back half (action).
+
+## Process Isolation
+
+- One worker per Sense group (long-lived)
+- One worker per Workflow type (on-demand)
+- Workers never talk to each other
+- All user code runs in isolated Workers; kernel never loads user code directly
+
+## Storage Systems
+
+- **Log Store** — SQLite with WAL mode for audit trails and workflow state
+- **Sense Databases** — Isolated SQLite per sense group for private data
+- **Knowledge Store** — Vector search index for project context
+- **Blob Store** — Content-addressable storage for large artifacts
+
+## Signal Flow
+
+Sense compute outputs are routed through signal routing logic that determines whether to emit a signal or trigger a workflow—never both simultaneously.

+nerve validate                # validate nerve.yaml config
+nerve dev                     # run kernel foreground (development, Ctrl+C to stop)

+nerve daemon                  # restart daemon (stop + start)
+```
+
+### Init Behavior
+
+**Default `nerve init`**: Creates workspace at `~/.uncaged-nerve/`. If this directory already exists and is non-empty, **exits with error** requiring `--force` flag. No merge/overwrite logic — prevents accidental workspace destruction.
+
+**Force mode `nerve init --force`**: Reinitializes workspace even if `~/.uncaged-nerve/` exists. **Preserves `data/` directory** (containing sense SQLite databases and logs) but overwrites all config files (`nerve.yaml`, `package.json`, etc.) and example senses.
+
+**Git clone `nerve init --from <url>`**: Clones existing repository to `~/.uncaged-nerve/`. Requires empty target directory — fails if workspace already exists and is non-empty.
+
+## Sense Management
+
+```bash
+nerve create sense <name>     # scaffold a new sense (compute.ts + schema.ts)
+nerve sense list              # list configured senses
+nerve sense trigger <name>    # manually trigger a sense compute
+nerve sense schema <name>     # show sense Drizzle schema
+nerve sense query <name>      # inspect sense SQLite database
+nerve sense query <name> --sql "SELECT * FROM samples LIMIT 5"
+```
+
+## Workflow Management
+
+```bash
+nerve create workflow <name>  # scaffold a new workflow
+nerve workflow trigger <name> --prompt "..." [--max-rounds N] [--dry-run]
+nerve workflow list           # list configured workflows
+nerve thread                  # list active (queued/started) workflow threads
+```
+
+## Knowledge
+
+```bash
+nerve knowledge sync          # chunk files per knowledge.yaml, compute embeddings → knowledge.db
+nerve knowledge query "text"  # search indexed knowledge (cosine similarity)
+nerve knowledge query -g "text"           # global search across all indexed repos
+nerve knowledge query --repo /path "text" # search specific repo
+```
+
+## Logs & Store
+
+```bash
+nerve logs                    # view daemon logs (last 50 lines)
+nerve logs -f                 # follow logs (tail -f style)

+# Nerve Coding Conventions
+
+## Functional-First
+
+- `type` over `interface`, `function` over `class`
+- No `this`, no inheritance, composition over inheritance
+- Immutability first: `Readonly<T>`, `as const`
+
+## No Optional Properties
+
+Never use `?:`. Use `T | null` for nullable fields. Use discriminated unions for mutually exclusive fields.
+
+```ts
+// ✅ Good
+type Config = { throttle: string | null }
+
+// ❌ Bad
+type Config = { throttle?: string }
+```
+
+## Error Handling
+
+- `Result<T, E>` for expected failures
+- `throw` only for programmer errors (bugs)
+- No try-catch for flow control
+
+### Result<T, E> Type
+
+Defined in `@uncaged/nerve-core` (`packages/core/src/result.ts`):
+
+```ts
+export type Result<T, E = Error> = { ok: true; value: T } | { ok: false; error: E };
+```
+
+**Discriminated union** with tagged `ok` field. Helper functions:
+- `ok(value)` → `{ ok: true, value }`
+- `err(error)` → `{ ok: false, error }`
+
+**Exhaustive handling**: Pattern is `if (!result.ok) { handle error }` then access `result.value`. 
+No compiler enforcement - relies on manual discipline and TypeScript's flow control analysis.
+
+## Naming
+
+| Type | Style |
+|------|-------|
+| Files | `kebab-case.ts` |
+| Types | `PascalCase` |
+| Functions/vars | `camelCase` |
+| Constants | `UPPER_SNAKE` |
+
+## Exports
+
+- Always named exports, never default
+- One module = one responsibility
+
+### Module Naming Conventions
+
+**Primary exports** use descriptive, unambiguous names:
+- Functions: `createXxx()`, `parseXxx()`, `xxxAgent()` (e.g., `createCursorAdapter`, `cursorAgent`)
+- Types: Domain-specific prefixes (e.g., `CursorAgentOptions`, `SenseComputeFn`, `ThreadContext`)
+- Constants: `UPPER_SNAKE_CASE` with context (e.g., `DEFAULT_SENSE_SIGNAL_RETENTION`, `CURSOR_ADAPTER_DEFAULT_MS`)
+
+**Avoiding ambiguity**:
+- Package-scoped naming: `@uncaged/nerve-adapter-cursor` exports `cursorAgent`, `createCursorAdapter`
+- Factory pattern: `createXxxAdapter()` for configurable instances, `xxxAdapter` for defaults
+- Descriptive type prefixes prevent collision (e.g., `CursorAgentOptions` vs `HermesAgentOptions`)
+
+## Async
+
+- Always `async/await`, never `.then()` chains
+- Use `AbortSignal` for cancellation: `AbortController` to create signals, pass to long-running operations
+- `spawn-safe.ts` and adapter functions accept `abortSignal: AbortSignal | null` parameter
+- On abort: child processes receive `SIGTERM`, async operations should check `signal.aborted`
+- No enforced Biome/Vitest rules for AbortSignal usage (manual discipline required)
+
+## No Dynamic Import
+
+Static `import` only. Exceptions: `sense-runtime.ts`, `workflow-worker.ts` (runtime module paths).
+
+## Toolchain
+
+pnpm + TypeScript (strict) + Biome (lint/format) + Vitest (test)
+
+```bash
+pnpm run check   # biome check
+pnpm test        # vitest
+pnpm run build   # full build
+```

+# Knowledge Layer (RFC-003 Phase 6)
+
+Local-first, repo-scoped knowledge base for project context.
+
+## Files
+
+- `knowledge.yaml` — repo root, defines include/exclude globs
+- `knowledge.db` — SQLite, stores chunks + embeddings
+- `.knowledge/` — curated knowledge cards (indexed by sync)
+
+## Commands
+
+```bash
+nerve knowledge sync              # chunk files, compute embeddings, write to knowledge.db
+nerve knowledge query "query"     # search by cosine similarity (or word overlap fallback)
+nerve knowledge query -g "query"  # global search across all indexed repos
+nerve knowledge query --repo /path "query"  # search specific repo
+```
+
+## Embedding
+
+- **Default model**: Dashscope text-embedding-v3 (1024 dimensions)
+- **Remote service**: configured via `EMBED_SERVICE_URL` env var (self-hosted Cloudflare Worker + KV cache)
+- **Model configuration**: No mechanism to specify alternate models — hardcoded to text-embedding-v3 in remote service
+- **Vector dimensions**: Fixed at 1024 (Float32Array, stored as 4096-byte Buffer blobs in SQLite)
+- **Cache**: content-addressable (sha256 of model+text), never expires
+- **Fallback**: word-overlap scoring when embed service not configured
+
+### Configuration
+
+The embedding model is **not configurable** through `knowledge.yaml` or other config files. The remote service at `embed.shazhou.workers.dev` uses Dashscope text-embedding-v3 exclusively. To use different models, you would need to:
+
+1. Deploy your own embedding service compatible with the same API
+2. Point `EMBED_SERVICE_URL` to your service
+3. Ensure vector dimensions match (1024) or modify knowledge database schema
+
+## Chunking
+
+- Markdown: split by headings, large sections split further by paragraphs (max 24)
+- TypeScript/JS: split by function declarations, fallback to paragraphs
+- Other files: single chunk
+
+## Env Config
+
+```
+EMBED_SERVICE_URL=https://embed.shazhou.workers.dev
+EMBED_AUTH_TOKEN=<token>

+# Sense
+
+A `compute()` function that samples or derives external data. The only first-class citizen in nerve.
+
+## Contract
+
+Each sense module (`src/index.ts`) must export:
+
+```ts
+export { snapshots as table } from "./schema.ts";  // drizzle table for runtime to insert into
+
+export async function compute(): Promise<ComputeResult<T>> { ... }  // pure, no args
+```
+
+**Function Signature & Input Schema:**
+- `compute()` is **parameterless** — no direct inputs, environment variables available
+- No database access within compute — runtime provides isolated execution context 
+- Must be pure function (no side effects, no external API calls)
+
+**Return Value Contract:**
+- `ComputeResult<T>` = `null | { signal: T; workflow: WorkflowTrigger | null }`
+  - `null` → silent, no storage, no signal  
+  - `{ signal: data, workflow: null }` → persist + emit signal
+  - `{ signal, workflow: WorkflowTrigger }` → persist + emit signal + trigger workflow
+  - Any other value → treated as `{ signal: value, workflow: null }`
+
+**Error Handling & Serialization:**
+- Exceptions caught by worker, logged as errors (no signal emitted)
+- Signal payload must be JSON-serializable (passed via IPC)
+- Invalid workflow triggers silently dropped (signal still emitted)
+
+**Timeout & Scheduling Semantics:**
+- Timeout priority: explicit config → AbortSignal → DEFAULT_TIMEOUT_MS (30s)
+- Enforced via `Promise.race()` with timeout promise
+- Grace period can trigger `process.exit(1)` after timeout (kills worker group)
+- Interval translation: YAML config values used directly as milliseconds in `setInterval()`
+- Jitter control: throttle mechanism prevents rapid-fire, single deferred trigger per throttle window
+
+## Config (nerve.yaml)
+
+```yaml
+senses:
+  cpu-usage:
+    group: system        # senses in same group share a worker
+    throttle: 10s        # min interval between computes
+    timeout: 30s         # max compute duration
+    grace_period: 5s     # wait before first compute
+    interval: 30s        # periodic trigger (optional)
+    on: [disk-pressure]  # trigger on signals from other senses (optional)
+```
+
+## Manual Trigger Context
+
+**`nerve sense trigger <name>`** sends IPC message to running daemon. The compute context is initialized as follows:
+
+- **SQLite Database**: Opened in **read-write mode** at `data/senses/<name>.db`
+- **Migrations**: All `*.sql` files in `senses/<name>/migrations/` applied in lexicographic order
+- **Environment**: Inherits daemon process environment (no special secrets injection)
+- **Arguments**: No runtime arguments or mock inputs supported — `compute()` is always pure function with no parameters
+- **Isolation**: Runs in forked child process (worker) with full filesystem access within user permissions
+- **Persistence**: Runtime automatically calls `db.insert(table).values(result.signal)` if compute returns non-null signal

+# Signal Routing
+
+Signal routing is the core mechanism that determines how Sense outputs flow through the Nerve system.
+
+## Routing Logic
+
+When a Sense `compute()` function returns non-null, the output goes through `routeSenseComputeOutput()` in `packages/core/src/sense-workflow-directive.ts`:
+
+```
+Sense compute() → non-null → routeSenseComputeOutput() → { signal, workflow }
+                           ↓
+          kernel.ts → signal ALWAYS emitted + optional workflow start
+```
+
+## Two Output Formats
+
+### 1. Explicit Format
+```typescript
+{
+  signal: any,           // emitted as signal
+  workflow: {           // optional workflow trigger
+    name: string,
+    maxRounds: number,
+    prompt: string,
+    dryRun: boolean
+  } | null
+}
+```
+
+### 2. Shorthand Format
+Any other value is treated as:
+```typescript
+{ signal: payload, workflow: null }
+```
+
+## Workflow Directive Parsing
+
+## Concrete Routing Predicates
+
+The routing decision is implemented in `routeSenseComputeOutput()` using these exact matching criteria:
+
+### 1. Explicit Format Detection
+```typescript
+if (isPlainRecord(payload) && Object.hasOwn(payload, "signal"))
+```
+- Payload must be a plain object
+- Must have `signal` property (any value)
+- Workflow extracted from `workflow` property or defaults to null
+
+### 2. Workflow Validation
+When workflow is non-null, it's validated via `parseWorkflowTrigger()`:
+- `name`: non-empty string (trimmed)  
+- `maxRounds`: positive integer >= 1
+- `prompt`: string
+- `dryRun`: boolean
+
+**Critical behavior**: Invalid workflows are silently dropped (become null) but signal emission continues. This prevents malformed workflow config from blocking signals.
+
+### 3. Fallback to Shorthand
+Any value that doesn't match explicit format becomes:
+```typescript
+{ signal: payload, workflow: null }
+```
+
+## Processing Flow
+
+```typescript
+// In kernel.ts handleSenseWorkerSignal()
+const { signal: signalPayload, workflow } = routeResult.value;
+
+// Signal is ALWAYS emitted when compute returns non-null
+bus.emit({ id, senseId, payload: signalPayload, timestamp });
+
+// Workflow is started ONLY if workflow is non-null
+if (workflow !== null) {
+  workflowManager.startWorkflow(workflow.name, { ... });
+}
+```
+
+## Legacy String Format (Deprecated)
+
+The old `"name|maxRounds|prompt"` string format is converted to the structured format internally but should not be used in new code.
+
+## Key Behaviors
+
+1. **Signal priority**: Every non-null compute result emits a signal, regardless of workflow
+2. **Additive behavior**: Valid workflow triggers are executed in addition to signal emission
+3. **Failure tolerance**: Invalid workflow directives are silently ignored, signal still emits
+4. **Structure-based routing**: No complex predicates - simply checks object structure and property existence
+
+This routing mechanism ensures clean separation between perception (signals) and action (workflows) while maintaining backward compatibility.

+# Storage Layer
+
+Nerve uses multiple storage systems designed for different data types and access patterns.
+
+## Core Storage Components
+
+### 1. Log Store (`logs.db`)
+Append-only audit trail implemented in SQLite with WAL mode.
+
+**Schema:**
+- `logs` — all system events (signals, workflow transitions, sense outputs)
+- `meta` — key-value store for system metadata
+- `workflow_runs` — materialized view of workflow execution state
+
+**Key Features:**
+- Atomic workflow state updates via transactions
+- Thread message persistence for crash recovery
+- Configurable log archival to JSONL files
+- Full-text search across log entries
+
+### 2. Sense Databases
+Each sense group gets its own SQLite database for private state.
+
+**Characteristics:**
+- Isolated per sense group (e.g., `system-senses.db`)
+- Managed by individual sense compute functions
+- Drizzle ORM integration for schema management
+- No cross-sense data sharing
+
+### 3. Knowledge Store (`knowledge.db`)
+Vector-enabled search index for project context.
+
+**Contents:**
+- Chunked source files with embeddings
+- Curated knowledge cards from `.knowledge/`
+- Semantic search capabilities
+- Global vs. repo-scoped search modes
+
+### 4. Blob Store (CAS)
+Content-addressable storage for large artifacts.
+
+**Design:**
+- SHA-256 based file naming
+- Automatic deduplication
+- Used for workflow artifacts and large payloads
+
+## Consistency & Isolation Mechanisms
+
+### SQLite WAL Mode
+All SQLite databases use `PRAGMA journal_mode=WAL` for:
+- **Writer-reader concurrency** — readers don't block writers
+- **Atomic writes** — each transaction is fully applied or rolled back
+- **Crash recovery** — WAL provides consistent state after crashes
+
+### Transaction Management
+
+#### Log Store Transactions
+Uses `BEGIN IMMEDIATE` transactions (`packages/store/src/log-store.ts`):
+```typescript
+function runInTransaction<T>(db: DatabaseSync, fn: () => T): T {
+  db.exec("BEGIN IMMEDIATE");  // Exclusive write lock
+  try {
+    const result = fn();
+    db.exec("COMMIT");
+    return result;
+  } catch (e) {
+    db.exec("ROLLBACK");
+    throw e;
+  }
+}
+```
+
+**Key Operations:**
+- `upsertWorkflowRun()` — atomically writes log entry + workflow state
+- `archiveLogs()` — transactional export + delete + watermark update
+
+#### Sense Database Isolation
+- Each sense group has its own SQLite file (e.g., `system-senses.db`)
+- No cross-sense transactions or coordination required
+- Independent schema migrations per sense
+- Private `_signals` table for signal history retention
+
+### Process-Level Isolation
+
+#### Worker Process Architecture
+- **One worker per sense group** — prevents data races within group
+- **One worker per workflow type** — isolated execution contexts  
+- **No shared memory** — all communication via IPC messages
+
+#### Concurrency Control
+Workflow manager enforces limits per workflow:
+```yaml
+workflows:
+  my-workflow:
+    concurrency: 2        # Max parallel threads
+    overflow: "queue"     # or "drop" 
+    maxQueue: 10         # Queue depth limit
+```
+
+### Consistency Guarantees & Failure Modes
+
+**Strong Consistency (Single Database)**:
+1. **Within Log Store** — ACID transactions with immediate consistency
+2. **Within Sense DB** — WAL mode ensures atomic commits per database
+3. **Workflow State** — `upsertWorkflowRun()` atomically updates log + materialized view
+
+**No Cross-Database Consistency**:
+- No distributed transactions across multiple SQLite files
+- Log Store and Sense Databases can temporarily diverge during failures
+- Signal emission and workflow triggering are separate, non-atomic operations
+
+**Failure Recovery Mechanisms**:
+- **Sense worker crash**: State rebuilt from sense SQLite database on respawn
+- **Workflow worker crash**: Thread state recovered from log store message history
+- **Kernel crash**: All workers respawned, state recovered from persistent stores
+- **Log Store corruption**: WAL recovery on database open
+- **Sense DB corruption**: Migrations re-run, `_signals` table rebuilt if needed
+
+**Rollback Scenarios**:
+- **Log write failure**: Transaction rolled back, no state changes persisted
+- **Sense compute failure**: Error logged, no signal/workflow emitted
+- **Workflow failure**: Thread marked as failed in materialized view
+- **IPC failure**: Worker respawned, pending operations lost (not rolled back)
+
+## Archive Strategy
+
+Logs older than retention window (default 30 days) are:
+1. Exported to `data/archive/logs/YYYY-MM-DD.jsonl`
+2. Deleted from active database
+3. Watermark updated to prevent re-processing
+
+This keeps the active database size bounded while preserving audit trails.

+# Worker Isolation
+
+Nerve's worker architecture ensures complete isolation between different types of user code while maintaining system stability.
+
+## Process Architecture
+
+```
+Kernel (Main Process)
+├── Sense Worker (Group A) ── sense-1, sense-2
+├── Sense Worker (Group B) ── sense-3, sense-4
+├── Workflow Worker (cleanup) ── cleanup workflow instances
+└── Workflow Worker (review) ── review workflow instances
+```
+
+## Isolation Boundaries
+
+### 1. Sense Workers
+- **One worker per sense group** (configured in `nerve.yaml`)
+- Groups share a child process but have isolated execution contexts
+- Crash in one sense doesn't affect other groups
+- Each group has its own SQLite database
+
+### 2. Workflow Workers  
+- **One worker per workflow type** (spawned on-demand)
+- Multiple threads of the same workflow share a worker process
+- Concurrency limits enforced at the workflow level
+- Workers terminate when no active threads remain
+
+### 3. Kernel Protection
+- **User code never runs in kernel process**
+- All `compute()` and workflow role functions run in workers
+- Kernel only handles IPC, scheduling, and coordination
+- System remains stable even with infinite loops or crashes in user code
+
+## Worker Lifecycle
+
+### Sense Workers
+```
+nerve daemon start → spawn worker per group → long-lived process
+                   → hot reload on file changes
+                   → respawn on crash
+```
+
+### Workflow Workers
+```
+workflow trigger → check existing worker → reuse or spawn
+                                       → execute thread
+                                       → terminate when idle
+```
+
+## Communication Patterns
+
+### Kernel ↔ Sense Worker
+- IPC via child process stdio
+- JSON-formatted messages
+- Worker reports signals back to kernel
+- Bidirectional: kernel can request immediate computes
+
+### Kernel ↔ Workflow Worker  
+- Similar IPC protocol
+- Workflow definition loaded in worker
+- Role execution results streamed back
+- Thread state managed in kernel
+
+## Resource Limits & Control
+
+### Timeout Enforcement
+Configurable timeouts per sense (in `nerve.yaml`):
+```yaml
+senses:
+  my-sense:
+    timeout: 30000      # Execution timeout (ms)
+    gracePeriod: 5000   # Grace period before hard kill
+```
+
+**Timeout Implementation:**
+- `AbortController` for async operations 
+- `Promise.race()` between compute and timeout
+- Grace period triggers `process.exit(1)` to kill entire worker group
+
+### Memory & CPU Limits
+**No Application-Level Resource Quotas**:
+- No memory caps, CPU throttling, or disk I/O limits enforced by Nerve
+- Workers can consume arbitrary system resources until OS limits
+- No cgroup/container isolation — full filesystem access within user permissions
+- No syscall filtering (no seccomp restrictions)
+
+**OS-Level Constraints Only**:
+- Process memory limited by system `ulimit -m` 
+- CPU usage bounded by scheduler only
+- Network requests unrestricted
+- Can spawn additional processes (not tracked by Nerve)
+
+### Concurrency Control
+
+#### Sense Workers
+- One active compute per sense at a time (serialized via promise chains)
+- No memory sharing between sense groups
+- Crash isolation: one sense crash doesn't affect other groups
+
+#### Workflow Workers
+Per-workflow limits configured in `nerve.yaml`:
+```yaml
+workflows:
+  my-workflow:
+    concurrency: 2        # Max parallel threads
+    overflow: "drop"      # or "queue"
+    maxQueue: 10         # Queue size limit
+```
+
+### Process Management
+
+#### Signal Handling
+Workers ignore session broadcast signals (SIGINT/SIGTERM):
+```typescript
+// Workers ignore terminal signals; kernel coordinates shutdown
+process.on("SIGINT", () => {}); 
+process.on("SIGTERM", () => {});
+```
+
+#### Graceful Shutdown & State Handoff
+**Sense Workers**:
+- IPC `shutdown` message → `process.exit(0)` (immediate)
+- No graceful termination period for senses
+- State rebuilt from SQLite on respawn (no handoff needed)
+
+**Workflow Workers**:
+- IPC `shutdown` → wait for in-flight threads to complete
+- Drain timeout: `WORKER_SHUTDOWN_TIMEOUT_MS` (10s)
+- If threads don't complete → `SIGKILL` force termination
+- Thread state preserved in log store for crash recovery
+
+**State Handoff Mechanism**:
+- No explicit state transfer between old/new workers
+- Sense workers: SQLite database contains full state
+- Workflow workers: Log store contains thread message history
+- Kernel coordinates recovery via `recoverThreadsForWorker()`
+
+## Failure Handling
+
+### Worker Crashes
+- **Sense workers**: Automatic respawn after 1s delay, state rebuilt from DB
+- **Workflow workers**: Crash recovery from log store thread messages  
+- **Kernel protection**: Main process continues, marks affected runs as crashed
+- **Crash limits**: Max 5 crashes per workflow in 60s window (prevents infinite respawn)
+
+### Resource Exhaustion
+- **Memory**: Worker process killed by OS, kernel respawns automatically
+- **Compute timeout**: Grace period → hard kill → respawn
+- **Infinite loops**: Timeout enforcement prevents hanging indefinitely
+

+# Workflow Engine
+
+Stateful multi-step execution driven by Roles and a Moderator.
+
+## Core Concepts
+
+- **Workflow** — definition with concurrency strategy
+- **Thread** — one execution instance, unique `runId`
+- **Role** — executes actions (has side effects). `(ctx: ThreadContext) → Promise<RoleResult<M>>`
+- **Moderator** — pure routing function. `(ctx: ThreadContext) → next role | END`
+
+## Thread Lifecycle
+
+```
+trigger → queued → started → step_complete ↺ → completed
+                                    ↓
+                              failed / crashed
+```
+
+## Concurrency Config (nerve.yaml)
+
+```yaml
+workflows:
+  cleanup:
+    concurrency: 1
+    overflow: drop       # discard if already running
+  code-review:
+    concurrency: 3
+    overflow: queue
+    max_queue: 20        # queue limit, oldest discarded
+```
+
+## createRole Helper
+
+`createRole` builds a `Role<M>` from an adapter, prompt, Zod schema, and extract config:
+
+```ts
+import { createRole } from "@uncaged/nerve-workflow-utils";
+import { cursorAdapter } from "@uncaged/nerve-adapter-cursor";
+import { z } from "zod";
+
+const coderSchema = z.object({ plan: z.string(), files: z.array(z.string()) });
+
+const coder = createRole(cursorAdapter, coderPrompt, coderSchema, {
+  provider: { baseUrl: "...", apiKey: "...", model: "qwen-plus" },
+});
+
+// Use in WorkflowDefinition
+const workflow: WorkflowDefinition<MyMeta> = {
+  name: "develop",
+  roles: { coder, reviewer },
+  moderator,
+};
+```
+
+- `adapter: AgentFn` — direct function reference
+- `prompt: string | ((ctx: ThreadContext) => Promise<string>)` — static or dynamic
+- `meta: z.ZodType<M>` — Zod schema, directly (no wrapper needed)
+- `extract: LlmExtractorConfig` — provider for structured extraction
+
+## Runtime Enforcement Mechanisms
+
+### Role Authority & Validation
+
+**Role Function Lookup**:
+- Roles accessed via `def.roles[nextRole]` dictionary lookup
+- Unknown roles trigger immediate workflow error (`Unknown role: ${nextRole}`)
+- No dynamic role registration during execution
+
+**Result Validation** (`validateRoleResult()`):
+```typescript
+// Required return shape from every role function
+{ content: string, meta: Record<string, unknown> }
+```
+- `content` must be string (non-string → workflow error)
+- `meta` must be plain object (array/null/primitive → workflow error)
+- Validation failure terminates thread immediately
+
+### Moderator Authority & Routing Control
+
+**Next Role Selection**:
+- Moderator must return role name from `roles` keys OR `END` symbol
+- Called after every role completion (receives full context)
+- No validation of role name until execution attempt
+- Pure function constraint: cannot perform side effects
+
+**Causal Chain Integrity**:
+- Moderator receives immutable **ThreadContext**: `{ threadId, start, steps }`
+- Steps array contains ALL role outputs in chronological order
+- No role can modify prior steps or start metadata
+- Thread context built from log store on crash recovery
+
+### Unauthorized Command Event Prevention
+
+**Message Flow Control**:
+- Role functions have NO direct access to kernel IPC
+- All outputs flow through `sendWorkflowMessage()` wrapper
+- Worker process validates messages before kernel transmission
+- No direct log store database access from roles
+
+**Process Isolation**:
+- Roles execute in forked worker processes (not kernel)
+- File system access limited to user permissions
+- No network isolation (roles can make arbitrary HTTP calls)
+- Worker has read/write access to workflow workspace only
+
+### Concurrent Thread Management
+
+**Kill Flag Implementation**:
+```typescript
+type KillFlag = { value: boolean };
+// Checked before role execution and after completion
+if (killFlag.value) {
+  sendThreadEvent(runId, "killed", { exitCode: 137 });
+  return;
+}
+```
+
+**Concurrency Enforcement**:
+- Workflow manager enforces per-workflow limits in kernel
+- Excess threads queued/dropped per overflow policy
+- No role can spawn additional threads (no access to workflow manager)

+## Core Concepts
+
+```
+External World → Sense → Signal → Workflow → Log
+                  ↑                                     ↑
+              "what to observe"                  "what to do"
+```
+
+**Nerve** is a lightweight observation engine daemon for autonomous agents. It continuously observes external state, reacts to changes via declarative rules, and orchestrates multi-step workflows.
+
+### Key Terms
+
+| Concept | What it is |
+|---------|-----------|
+| **Sense** | A `compute()` function that samples or derives data. Returns `ComputeResult<T>` — non-null emits a Signal (and optionally triggers a Workflow), null is silent. Each Sense has its own SQLite database. Scheduling (interval, on) is configured in nerve.yaml. |
+| **Signal** | A notification emitted when a Sense returns non-null. Pure fact, no intent. Distributed via an in-memory Signal Bus. Not persisted. |
+| **Workflow** | A stateful multi-step execution. Contains **Roles** (actors with side effects) and a **Moderator** (pure router). Each instance is a **Thread** with a unique `runId`. |
+| **Log** | Immutable audit trail. Records executions, state transitions, errors. Cannot trigger Senses — prevents feedback loops. |
+| **Engine** | The kernel orchestrating everything. Holds Signal Bus, Process Manager, Workflow Manager. Never loads user code directly — all user code runs in isolated Workers. |
+| **Daemon** | The `nerve-daemon` package — engine runtime. Runs as a background process. |
+
+### Architecture Rules
+
+- **Two extension points**: Sense (what to observe + when), Workflow (what to do)
+- **Process isolation**: One worker per Sense group (long-lived), one per Workflow type (on-demand). Workers never talk to each other.
+- **Causality is one-directional**: External world → Sense → Signal → Workflow + Log. Logs are the end of the chain.
+
+
+
+## Language & Paradigm
+
+### Functional-first
+
+Use `function` + `type`, not `class` + `interface`.
+
+```typescript
+// ✅ Good
+type Signal = {
+  senseId: string;
+  value: unknown;
+  ts: number;
+};
+
+function createSignal(senseId: string, value: unknown): Signal {
+  return { senseId, value, ts: Date.now() };
+}
+
+// ❌ Bad — no class, no interface
+class Signal implements ISignal { ... }
+```
+
+### Rules
+
+| Rule | Description |
+|------|-------------|
+| `type` over `interface` | All type definitions use `type` |
+| `function` over `class` | Pure functions + closures, no class |
+| No `this` | Functions must not depend on `this` context |
+| No inheritance | No `extends`, `implements`, `abstract` |
+| Composition over inheritance | Use function composition |
+| Immutability first | Use `Readonly<T>`, `as const`, avoid mutation |
+| No optional properties | Use `T \| null` instead of `?:` — see below |
+
+### Exceptions
+
+Classes are allowed when:
+- Required by a third-party library (e.g. Drizzle's `sqliteTable`)
+- Error subclasses (`class NerveError extends Error`)
+
+### No Optional Properties
+
+Never use `?:`. All nullable fields must be explicit `T | null`.
+
+```typescript
+// ✅ Good
+type SenseConfig = {
+  group: string;
+  throttle: string | null;
+  timeout: string | null;
+};
+
+// ❌ Bad
+type SenseConfig = {
+  group: string;
+  throttle?: string;
+  timeout?: string;
+};
+```
+
+For mutually exclusive fields, use discriminated unions:
+
+```typescript
+// ✅ Good
+type ComputeResult<T> =
+  | null
+  | { signal: T; workflow: WorkflowTrigger | null };
+```
+
+### Workflow authoring (user modules)
+
+Roles and moderators take **ThreadContext** (`threadId`, `start`, `steps`) — not separate `StartStep` / message arrays.
+
+```typescript
+import type { RoleResult, ThreadContext, WorkflowDefinition } from "@uncaged/nerve-core";
+import { END } from "@uncaged/nerve-core";
+
+type MyMeta = { round: number };
+
+async function planner(ctx: ThreadContext): Promise<RoleResult<MyMeta>> {
+  void ctx.start;
+  void ctx.steps;
+  return { content: "plan", meta: { round: ctx.steps.length } };
+}
+
+const workflow: WorkflowDefinition<Record<"planner", MyMeta>> = {
+  name: "example",
+  roles: { planner },
+  moderator(ctx: ThreadContext<Record<"planner", MyMeta>>) {
+    return ctx.steps.length === 0 ? "planner" : END;
+  },
+};
+```
+
+## Modules & Exports
+
+- Always named exports, never default exports
+- One module = one responsibility, filename = purpose
+
+## Naming
+
+| Type | Style | Example |
+|------|-------|---------|
+| Files | kebab-case | `signal-bus.ts` |
+| Types | PascalCase | `SignalBus` |
+| Functions/variables | camelCase | `createSignalBus` |
+| Constants | UPPER_SNAKE | `MAX_RETRY_COUNT` |
+| Generics | Single letter or descriptive | `T`, `TValue` |
+
+## Error Handling
+
+- Use `Result` type for expected failures
+- `throw` only for unrecoverable bugs (programmer errors)
+- No try-catch for flow control
+
+```typescript
+type Result<T, E = Error> = { ok: true; value: T } | { ok: false; error: E };
+```
+
+## Async
+
+- Always `async/await`, never `.then()` chains
+
+## No Dynamic Import
+
+Do NOT use `await import()` in production code. Always use static top-level `import`.
+
+Exceptions (must include a comment):
+1. `sense-runtime.ts` — user module paths known only at runtime
+2. `workflow-worker.ts` — user module paths known only at runtime
+
+Test files (`__tests__/**`) are exempt.
+
+## Toolchain
+
+| Tool | Purpose |
+|------|---------|
+| **pnpm** | Package manager |
+| **TypeScript** | Type checking (strict mode) |
+| **Biome** | Lint + format (replaces ESLint + Prettier) |
+| **tsup** | Bundling |
+
+### Commands
+
+```bash
+pnpm run check      # biome check (lint + format)
+pnpm run format     # biome format --write
+pnpm run build      # full build
+pnpm test           # run tests
+```
+
+## Monorepo Structure
+
+```
+nerve/
+  packages/
+    core/           # @nerve/core — shared types and utils
+    cli/            # @nerve/cli — CLI entry point
+    daemon/         # @nerve/daemon — engine runtime
+  docs/             # RFCs, conventions

+- `core` is the shared layer; `cli` and `daemon` both depend on it
+- `cli` and `daemon` must NOT depend on each other

-Observation engine — Sense, Reflex, Workflow
+**Observation engine for autonomous agents** — sense the world, react to changes, run workflows.
+
+Nerve is a lightweight daemon that continuously observes external state through **Senses**, reacts via declarative **Reflexes**, and orchestrates multi-step **Workflows**. Built for the [Uncaged](https://github.com/uncaged) agent framework.
+
+## Core Concepts
+
+```
+External World → Sense ─┬→ Signal → Reflex → Sense (scheduled compute)
+                        │
+                        └→ Workflow (Sense return with workflow directive) → Log
+```
+
+| Concept | Metaphor | Role |
+|---------|----------|------|
+| **Sense** | 👁️ Perception | A `compute()` function that samples or derives data. Each sense has its own SQLite database. |
+| **Reflex** | ⚡ Reaction | Declarative rules that **only schedule Sense computes** (interval and/or `on` signal names). Reflex YAML cannot reference workflows. |
+| **Signal** | 📡 Notification | Emitted when a sense returns a non-null value that is routed as a normal signal (see Sense → Workflow below). Other reflexes can listen via `on`. |
+| **Workflow** | 🔧 Action | Stateful multi-step execution with Roles and a Moderator. Started from a Sense return value or from CLI/daemon IPC—not from reflex YAML. |
+| **Log** | 📝 Record | Immutable audit trail. Queryable by senses, but **cannot** trigger reflexes (prevents feedback loops). |
+
+**Sense → Workflow:** if `compute()` returns a plain object with a string field `workflow` in the form `name|maxRounds|prompt` (only the first two `|` delimit name and rounds; the rest is the prompt), the engine starts that workflow and **does not** emit a Signal for that return. `workflow: null` or `""` means “emit a signal” and strip the key from the payload. Invalid `workflow` strings are treated like a normal signal (directive stripped). See `@uncaged/nerve-core` `routeSenseComputeOutput` / `parseSenseWorkflowDirective`.
+
+Three extension points for **what / when / multi-step action** — reflexes never replace Sense-driven workflow launches.
+
+## Packages
+
+| Package | Description |
+|---------|-------------|
+| [`@uncaged/nerve-core`](./packages/core) | Shared types, config parser, Sense→workflow routing, daemon IPC protocol |
+| [`@uncaged/nerve-store`](./packages/store) | Append-only log SQLite, JSONL archive, CAS blob store, workflow run rows |
+| [`@uncaged/nerve-daemon`](./packages/daemon) | Kernel, workers, signal bus, sense scheduler, workflow manager, file watcher, IPC |
+| [`@uncaged/nerve-cli`](./packages/cli) | CLI (`nerve`) — init, validate, daemon, dev, logs, sense, store, workflow |
+
+## Quick Start
+
+```bash
+# Requirements: Node.js ≥ 22.5, pnpm
+pnpm add -g @uncaged/nerve-cli
+
+# Initialize a workspace
+mkdir my-agent && cd my-agent
+nerve init
+
+# Write a sense
+cat > senses/cpu-usage/compute.ts << 'EOF'
+export async function compute() {
+  const [load] = (await import("node:os")).loadavg();
+  return load > 2.0 ? { load } : null;  // signal only when load is high
+}
+EOF
+
+# Configure reflexes in nerve.yaml
+cat > nerve.yaml << 'EOF'
+senses:
+  cpu-usage:
+    group: system
+    throttle: 10s
+
+reflexes:
+  - kind: sense
+    sense: cpu-usage
+    interval: 30s
+EOF
+
+# Run
+nerve dev          # foreground (development)
+nerve daemon start # background (production)
+nerve status       # check health
+nerve logs         # view logs
+```
+
+## Configuration
+
+`nerve.yaml` declares senses, reflexes (sense-only), optional workflows (concurrency), and optional engine `max_rounds`:
+
+```yaml
+max_rounds: 100              # default moderator cap (e.g. CLI workflow trigger)
+
+senses:
+  cpu-usage:
+    group: system          # senses in the same group share a worker process
+    throttle: 10s          # min interval between computes
+    timeout: 30s           # max compute duration
+    grace_period: 5s       # wait before first compute after startup
+
+reflexes:
+  - kind: sense
+    sense: cpu-usage
+    interval: 30s          # periodic trigger
+    on: [disk-pressure]    # also trigger on signals from other senses
+
+workflows:
+  cleanup:
+    concurrency: 1
+    overflow: drop         # discard if already running
+  code-review:
+    concurrency: 3
+    overflow: queue
+    max_queue: 20
+```
+
+YAML must **not** include `workflow:` under `reflexes` — the parser rejects it. Declare workflows under `workflows:` and start them from Sense `compute()` or `nerve workflow trigger`.
+
+**Example — Sense starts a workflow** (`senses/disk-pressure/compute.ts`):
+
+```typescript
+export async function compute() {
+  const full = await diskNearlyFull();
+  if (!full) return null;
+  return {
+    path: "/data",
+    workflow: "cleanup|10|Disk partition nearly full", // name|maxRounds|prompt
+  };
+}
+```

+# Khala MVP Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Build Khala — a Cloudflare Workers + D1 + Durable Objects cloud workflow orchestrator that lets agents coordinate multi-agent workflows as a stateless worker pool.
+
+**Architecture:** Khala is a CF Worker that receives events from agents via REST API. Each workflow thread runs in a Durable Object with a JSONata moderator. Agents poll a task queue for unclaimed turns, execute locally, and POST results back. Thread messages are stored in D1.
+
+**Tech Stack:** Cloudflare Workers, D1 (SQLite), Durable Objects, Hono (routing), JSONata (moderator engine), TypeScript
+
+---
+
+## Phase 0: Project Scaffolding
+
+### Task 0.1: Create khala package
+
+**Objective:** Set up the `packages/khala` CF Worker project with wrangler, Hono, and D1 binding.

+
+**Step 2: Create wrangler.toml**
+
+```toml

+
+## Phase 1: D1 Schema & Data Layer
+
+### Task 1.1: Create D1 migration — core tables
+
+**Objective:** Define D1 schema for agents, threads, messages, and task queue.
+
+**Files:**
+- Create: `packages/khala/migrations/0001_initial.sql`
+
+**SQL:**
+
+```sql
+-- Agent registry
+CREATE TABLE agents (
+  id TEXT PRIMARY KEY,           -- agent name (e.g. "tuanzi")
+  token_hash TEXT NOT NULL,      -- bcrypt/sha256 hash of agent token
+  created_at TEXT NOT NULL DEFAULT (datetime('now'))
+);
+
+-- Workflow threads
+CREATE TABLE threads (
+  id TEXT PRIMARY KEY,           -- ulid
+  workflow TEXT NOT NULL,        -- workflow name (e.g. "code-review")
+  status TEXT NOT NULL DEFAULT 'active',  -- active | completed | failed
+  initiator TEXT NOT NULL,       -- agent id or external caller
+  result TEXT,                   -- final result JSON (set on completion)
+  created_at TEXT NOT NULL DEFAULT (datetime('now')),
+  updated_at TEXT NOT NULL DEFAULT (datetime('now'))
+);
+
+-- Thread messages (append-only)
+CREATE TABLE messages (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  thread_id TEXT NOT NULL REFERENCES threads(id),
+  role TEXT NOT NULL,            -- role name or "__moderator__"
+  content TEXT NOT NULL,
+  meta TEXT,                     -- JSON
+  step INTEGER NOT NULL,         -- 0-indexed step number
+  agent_id TEXT,                 -- which agent executed this turn
+  created_at TEXT NOT NULL DEFAULT (datetime('now'))
+);
+
+CREATE INDEX idx_messages_thread ON messages(thread_id, step);
+
+-- Task queue
+CREATE TABLE tasks (
+  id TEXT PRIMARY KEY,           -- ulid
+  thread_id TEXT NOT NULL REFERENCES threads(id),
+  role TEXT NOT NULL,
+  instruction TEXT NOT NULL,     -- turn instruction from moderator
+  status TEXT NOT NULL DEFAULT 'open',  -- open | claimed | completed | expired
+  claim_id TEXT,                 -- set when claimed
+  claimed_by TEXT,               -- agent id
+  claimed_at TEXT,
+  timeout_seconds INTEGER NOT NULL DEFAULT 300,
+  created_at TEXT NOT NULL DEFAULT (datetime('now'))
+);
+
+CREATE INDEX idx_tasks_status ON tasks(status, created_at);
+```
+
+**Step 1: Write the migration file**
+
+**Step 2: Apply locally**
+
+```bash
+cd packages/khala
+pnpm exec wrangler d1 migrations apply khala --local
+```
+
+**Step 3: Commit**
+
+```bash
+git add packages/khala/migrations/
+git commit -m "feat(khala): D1 schema — agents, threads, messages, tasks"
+```
+
+### Task 1.2: Create data access functions
+
+**Objective:** Type-safe D1 query functions for all tables.
+
+**Files:**
+- Create: `packages/khala/src/db.ts`
+- Create: `packages/khala/src/types.ts`
+
+**types.ts:**
+
+```typescript
+export type Agent = {
+  id: string;
+  token_hash: string;
+  created_at: string;
+};
+
+export type Thread = {
+  id: string;
+  workflow: string;
+  status: "active" | "completed" | "failed";
+  initiator: string;
+  result: string | null;
+  created_at: string;
+  updated_at: string;
+};
+
+export type Message = {
+  id: number;
+  thread_id: string;
+  role: string;
+  content: string;
+  meta: string | null;
+  step: number;
+  agent_id: string | null;
+  created_at: string;
+};
+
+export type Task = {
+  id: string;
+  thread_id: string;
+  role: string;
+  instruction: string;
+  status: "open" | "claimed" | "completed" | "expired";
+  claim_id: string | null;
+  claimed_by: string | null;
+  claimed_at: string | null;
+  timeout_seconds: number;
+  created_at: string;
+};
+```
+
+**db.ts:** Query functions — `createThread`, `appendMessage`, `createTask`, `claimTask`, `completeTask`, `getOpenTasks`, `getThreadMessages`, etc. Each is a plain function taking `D1Database` as first arg.
+
+**Step 1: Write types.ts**
+
+**Step 2: Write db.ts with all query functions**
+
+Key functions:
+- `createThread(db, workflow, initiator) → Thread`
+- `appendMessage(db, threadId, role, content, meta, step, agentId) → Message`
+- `createTask(db, threadId, role, instruction, timeoutSeconds) → Task`
+- `claimTask(db, taskId, agentId) → { ok: true, claimId } | { ok: false }`
+- `completeTask(db, taskId, claimId) → boolean`
+- `expireTimedOutTasks(db) → number` (count expired)
+- `getOpenTasks(db, limit) → Task[]`
+- `getThreadMessages(db, threadId, opts?) → Message[]` (opts: role, since, step, last)
+
+Use `ulid()` for IDs (add `ulidx` dependency).
+
+**Step 3: Commit**
+
+```bash
+git add packages/khala/src/
+git commit -m "feat(khala): data access layer — types and D1 queries"
+```
+
+---
+
+## Phase 2: Auth & Agent Registry
+
+### Task 2.1: Agent auth middleware
+
+**Objective:** Bearer token auth for agents. Hash-based token verification.
+
+**Files:**
+- Create: `packages/khala/src/auth.ts`
+- Modify: `packages/khala/src/index.ts`
+
+**auth.ts:**
+
+```typescript
+import { createMiddleware } from "hono/factory";
+import type { Env } from "./index.ts";
+
+export const agentAuth = createMiddleware<{ Bindings: Env }>(async (c, next) => {
+  const header = c.req.header("Authorization");
+  if (!header?.startsWith("Bearer ")) {
+    return c.json({ error: "missing token" }, 401);
+  }
+  const token = header.slice(7);
+  const hash = await sha256(token);
+  const agent = await c.env.DB.prepare(
+    "SELECT id FROM agents WHERE token_hash = ?"
+  ).bind(hash).first<{ id: string }>();
+  if (!agent) {
+    return c.json({ error: "invalid token" }, 401);
+  }
+  c.set("agentId", agent.id);
+  await next();
+});
+
+async function sha256(input: string): Promise<string> {
+  const data = new TextEncoder().encode(input);
+  const buf = await crypto.subtle.digest("SHA-256", data);
+  return [...new Uint8Array(buf)].map(b => b.toString(16).padStart(2, "0")).join("");
+}
+```
+
+### Task 2.2: Admin routes for agent management
+
+**Objective:** Admin API to register/remove agents (protected by admin secret in env).
+
+**Files:**
+- Create: `packages/khala/src/routes/admin.ts`
+
+**Routes:**
+- `POST /admin/agents` — body `{ id, token }` → hash token, insert agent
+- `DELETE /admin/agents/:id` — remove agent
+- `GET /admin/agents` — list agents (no tokens)
+
+Protected by `ADMIN_SECRET` env var check.
+
+**Commit:**
+
+```bash
+git commit -m "feat(khala): agent auth middleware and admin API"
+```
+
+---
+
+## Phase 3: Workflow Engine (Durable Object)
+
+### Task 3.1: Workflow registry
+
+**Objective:** Load workflow definitions from a simple in-memory registry (hardcoded for MVP, later from D1 or KV).
+
+**Files:**
+- Create: `packages/khala/src/workflows.ts`
+
+**Structure:**
+
+```typescript
+export type CloudRole = {
+  prompt: string;
+};
+
+export type CloudWorkflowDef = {
+  name: string;
+  roles: Record<string, CloudRole>;
+  moderator: string;  // JSONata expression
+};
+
+// For MVP: hardcoded registry
+const registry = new Map<string, CloudWorkflowDef>();
+
+export function registerWorkflow(def: CloudWorkflowDef): void {
+  registry.set(def.name, def);
+}
+
+export function getWorkflow(name: string): CloudWorkflowDef | null {
+  return registry.get(name) ?? null;
+}
+```
+
+### Task 3.2: ThreadDO — Durable Object
+
+**Objective:** Each workflow thread runs as a Durable Object. The DO manages the moderator state machine, creates tasks, and processes responses.
+
+**Files:**
+- Create: `packages/khala/src/thread-do.ts`
+
+**Key behavior:**
+
+1. `POST /start` — Initialize thread: save workflow def, run moderator to get first turn, create task
+2. `POST /response` — Agent posts turn result: validate claim_id, append message, run moderator for next turn or END
+3. `GET /messages` — Query thread messages with filters
+
+**Moderator execution:**
+- Build context from messages (start frame + role steps)
+- Evaluate JSONata expression → returns `{ role: "reviewer" }` or `{ role: "__end__" }`
+- If not END, create new task in queue
+- If END, mark thread completed, set result
+
+**Important:** The DO holds workflow state in memory during the request but persists everything to D1. The DO itself uses `ctx.storage` only for the thread ID mapping.
+
+### Task 3.3: Wire ThreadDO into worker
+
+**Objective:** Export the DO class, add routes that proxy to the DO.
+
+**Files:**
+- Modify: `packages/khala/src/index.ts`
+
+**Routes:**
+- `POST /workflows/:name/threads` — Create thread → instantiate DO → start
+- `POST /threads/:id/response` — Forward to DO
+- `GET /threads/:id/messages` — Forward to DO (or query D1 directly)
+- `GET /threads/:id` — Thread status
+
+**Commit:**
+
+```bash
+git commit -m "feat(khala): ThreadDO workflow engine with JSONata moderator"
+```
+
+---
+
+## Phase 4: Task Queue API
+
+### Task 4.1: Task queue endpoints
+
+**Objective:** Agents poll for work and claim tasks.
+
+**Files:**
+- Create: `packages/khala/src/routes/tasks.ts`
+
+**Routes (all require agentAuth):**
+- `GET /tasks` — List open tasks (optionally filter by workflow)
+- `POST /tasks/:id/claim` — Claim a task → returns `{ claimId, role, instruction, threadId }`
+- `POST /tasks/:id/release` — Release a claimed task back to queue
+
+**Claim logic:**
+- Atomic: UPDATE ... WHERE status = 'open' → if rowsWritten = 0, already claimed
+- Returns claim_id (ulid) for optimistic lock on response
+
+### Task 4.2: Task timeout sweep
+
+**Objective:** Periodically expire timed-out tasks back to open.
+
+**Implementation:** CF Worker Cron Trigger (every 1 minute) that calls `expireTimedOutTasks(db)`.
+
+**Files:**
+- Modify: `packages/khala/src/index.ts` (add scheduled handler)
+- Modify: `packages/khala/wrangler.toml` (add cron trigger)
+
+```toml
+[triggers]
+crons = ["* * * * *"]
+```
+
+**Commit:**
+
+```bash
+git commit -m "feat(khala): task queue API with claim/release and timeout sweep"
+```
+
+---
+
+## Phase 5: Agent-Side Integration (KhalaSense)
+
+### Task 5.1: Khala client library
+
+**Objective:** A small client that agents use to interact with Khala.
+
+**Files:**
+- Create: `packages/core/src/khala-client.ts`
+
+**API:**
+
+```typescript
+export type KhalaClientConfig = {
+  baseUrl: string;
+  token: string;
+};
+
+export function createKhalaClient(config: KhalaClientConfig) {
+  return {
+    pollTasks: () => GET /tasks,
+    claimTask: (taskId) => POST /tasks/:id/claim,
+    submitResponse: (threadId, content, meta, claimId) => POST /threads/:id/response,
+    getMessages: (threadId, opts) => GET /threads/:id/messages,
+  };
+}
+```
+
+### Task 5.2: KhalaSense
+
+**Objective:** A Sense that polls Khala for open tasks and emits signals.
+
+**Files:**
+- Create: `packages/daemon/src/senses/khala-sense.ts`
+
+**Behavior:**
+- `compute()`: poll `/tasks`, if tasks available → return task info as signal value
+- Reflex picks up signal → triggers a workflow that executes the turn locally
+- After local execution → POST response back to Khala
+
+**This task depends on understanding the existing Sense pattern in daemon. Check `packages/daemon/src/` for examples.**
+
+**Commit:**
+
+```bash
+git commit -m "feat(khala): KhalaSense — agent-side polling and integration"
+```
+
+---
+
+## Phase 6: End-to-End Demo
+
+### Task 6.1: Register a demo workflow
+
+**Objective:** Register a simple 2-role "ping-pong" workflow for testing.
+
+**Files:**
+- Create: `packages/khala/src/workflows/ping-pong.ts`
+
+**Workflow:**
+- Roles: `pinger` (says ping), `ponger` (says pong)
+- Moderator: alternate pinger/ponger for 3 rounds then END
+- JSONata: `steps.length >= 6 ? { "role": "__end__" } : steps.length % 2 = 0 ? { "role": "pinger" } : { "role": "ponger" }`
+
+### Task 6.2: Integration test
+
+**Objective:** Test the full flow with miniflare.
+
+**Files:**
+- Create: `packages/khala/src/__tests__/e2e.test.ts`
+
+**Test:**
+1. Create thread via API
+2. Poll tasks → get first task
+3. Claim task
+4. POST response
+5. Poll again → get next task
+6. Repeat until workflow completes
+7. Verify thread status = completed and all messages present
+
+**Commit:**
+
+```bash
+git commit -m "feat(khala): ping-pong demo workflow and e2e test"
+```

+# RFC-003: Agent Configuration Layer
+
+**Author:** 小橘 🍊（NEKO Team）
+**Status:** Draft
+**Created:** 2026-04-29
+
+## Summary
+
+Define a minimal agent abstraction where **adapter = capability** and **role = scenario**. Workflows directly declare which adapter each role uses — no intermediate registry or `nerve.yaml` agent config. `nerve.yaml` only holds `extract` config and `knowledge` settings.
+
+## Motivation
+
+The original design introduced a `nerve.yaml` agents registry to map logical names (e.g. `developer`) to adapter implementations. In practice this added an unnecessary layer of indirection:
+
+- **Agent names are arbitrary** — `developer` vs `coder` vs `engineer` is a naming exercise, not architecture
+- **One more config to maintain** — adding/changing an adapter requires editing both `nerve.yaml` and the workflow
+- **Same adapter, same config** — in reality, most workflows just need "use cursor" or "use hermes", not a named abstraction on top
+
+The simpler model: **workflow roles declare their adapter directly**. The adapter *is* the capability.
+
+## Key Concepts
+
+### Adapter vs Role
+
+| | Adapter | Role |
+|---|---|---|
+| **What** | Capability — what tools are available | Scenario — what to do with those tools |
+| **Granularity** | Few (cursor, hermes, claude, codex) | Many (per workflow step) |
+| **Defines** | How to spawn an agent, tool access | Prompt, schema, timeout |
+| **Layer** | Infrastructure (packages) | Business logic (WorkflowSpec) |
+
+A `cursor` adapter becomes an architect, coder, or reviewer depending on the role's prompt. The adapter defines *what it can do*; the role defines *what it does right now*.
+
+### Agent Protocol
+
+All agent types implement a single unified interface:
+
+```ts
+type AgentFn = (prompt: string, context: WorkflowContext) => Promise<string>
+```
+
+- **Input**: prompt (assembled by Role) + context (start frame + prior messages + workdir + abort signal)
+- **Output**: raw string — structured data is extracted separately
+- **Internals**: adapter handles tool-specific details (cursor CLI, hermes subagent, codex API, etc.)
+
+Workflow runtime never interacts with agent internals.
+
+### Extract Layer
+
+A separate concern that parses agent output (raw string) into typed meta:
+
+```ts
+type ExtractFn<T> = (raw: string, schema: Schema<T>) => Promise<T>
+```
+
+Configured globally in `nerve.yaml`, overridable per role (two-level merge: global → role).
+
+**Error handling**: retry once (feed raw output + parse error back to LLM for correction), then throw `ExtractError`. The workflow moderator decides the recovery strategy (retry role, skip, or terminate) — extract never makes workflow-level decisions.
+
+## Design
+
+### Configuration (`nerve.yaml`)
+
+`nerve.yaml` holds only extract and knowledge config — no agent registry:
+
+```yaml
+extract:
+  provider: dashscope
+  model: qwen-plus
+```
+
+### Workflow Definition (TypeScript)
+
+Roles declare their adapter directly — no indirection through named agents:
+
+```ts
+import { cursorAdapter, createCursorAdapter } from "@uncaged/nerve-adapter-cursor";
+import { hermesAdapter } from "@uncaged/nerve-adapter-hermes";
+
+const workflow: WorkflowSpec<MyMeta> = {
+  name: "develop-workflow",
+  roles: {
+    architect: { adapter: cursorAdapter,  prompt: architectPrompt, meta: architectSchema },
+    coder:     { adapter: createCursorAdapter({ model: "claude-sonnet-4", timeout: 600 }), prompt: coderPrompt, meta: coderSchema },
+    reviewer:  { adapter: hermesAdapter,  prompt: reviewPrompt,    meta: reviewSchema },
+    deployer:  { adapter: hermesAdapter,  prompt: deployPrompt,    meta: deploySchema },
+  },
+  moderator,
+};
+```
+
+### Runtime Assembly
+
+```
+WorkflowSpec      →  Role(adapter fn + prompt)  →  adapter(prompt, ctx) → string
+                                                                            ↓
+nerve.yaml#extract →  ExtractFn(string, schema) → T (typed meta)
+```
+
+Adapter is a direct function reference on each role — no map, no lookup, no registry.
+
+### Adapter Packages
+
+Each agent adapter lives in its own package to avoid pulling unnecessary dependencies:
+
+```
+packages/
+  adapter-cursor/     # @uncaged/nerve-adapter-cursor — cursor-agent CLI
+  adapter-hermes/     # @uncaged/nerve-adapter-hermes — hermes CLI subagent
+  adapter-claude/     # @uncaged/nerve-adapter-claude — claude-code CLI (future)
+  adapter-codex/      # @uncaged/nerve-adapter-codex — codex CLI (future)
+```
+
+Each adapter exports a **default instance** and a **factory** for customization:
+
+```ts
+// @uncaged/nerve-adapter-cursor
+import type { AgentConfig, AgentFn } from "@uncaged/nerve-core";
+
+// Factory — custom config
+export function createCursorAdapter(config: AgentConfig): AgentFn;
+
+// Default — sensible defaults (model: "auto", timeout: 300)
+export const cursorAdapter: AgentFn;
+```
+
+The factory receives adapter config (model, timeout) and returns an `AgentFn` that spawns the CLI tool, passes the prompt, and returns raw output.
+
+**Wiring** — workflows import adapters directly, no daemon-level registry:
+
+```ts
+import { cursorAdapter } from "@uncaged/nerve-adapter-cursor";
+import { hermesAdapter } from "@uncaged/nerve-adapter-hermes";
+
+// Use default instances directly in roles
+{ adapter: cursorAdapter, prompt: "...", meta: schema }
+```
+
+Adapters not installed simply can't be imported — TypeScript catches missing dependencies at compile time.
+
+**Workspace `package.json`** only lists the adapters it actually uses:
+
+```json
+{
+  "dependencies": {
+    "@uncaged/nerve-adapter-cursor": "workspace:*",
+    "@uncaged/nerve-adapter-hermes": "workspace:*"
+  }
+}
+```
+
+**Migration from `workflow-utils`** — the existing `role-cursor.ts` / `shared/cursor-agent.ts` spawn logic moves to `@uncaged/nerve-adapter-cursor`. `role-hermes.ts` / `shared/hermes-agent.ts` moves to `@uncaged/nerve-adapter-hermes`. `workflow-utils` retains only extract, prompt utilities, and shared spawn infrastructure.
+
+### Dynamic Prompts
+
+`RoleSpec.prompt` supports both static strings and async functions:
+
+```ts
+type PromptInput = string | ((start: StartStep, messages: WorkflowMessage[]) => Promise<string>);
+
+type RoleSpec<M> = {
+  adapter: AgentFn;
+  prompt: PromptInput;
+  meta: Schema<M>;
+};
+```
+
+Static prompts cover simple cases. Dynamic prompts (functions) are needed when the prompt depends on thread context — e.g. reading issue content, injecting prior step results, or resolving repo paths at runtime.
+
+### Timeout Resolution
+
+Timeout is an **adapter concern**, not a role concern. Roles define *what to do* (prompt + schema); adapters define *how to do it* (tool, model, timeout).
+
+When different roles need different timeouts, create separate adapter instances:
+
+```ts
+import { cursorAdapter, createCursorAdapter } from "@uncaged/nerve-adapter-cursor";
+
+const fastCursor = createCursorAdapter({ model: "auto", timeout: 60 });
+const slowCursor = createCursorAdapter({ model: "auto", timeout: 600 });
+
+roles: {
+  reviewer: { adapter: fastCursor, prompt: reviewPrompt, meta: reviewSchema },
+  coder:    { adapter: slowCursor, prompt: coderPrompt,  meta: coderSchema },
+}
+```
+
+### No Runtime Fallback
+
+- **`nerve init`** — detects agent availability (CLI exists? service reachable?), reports errors immediately
+- **Runtime** — if an agent is unavailable, the workflow fails with a clear error. No silent degradation.
+
+Rationale: silent fallback hides quality differences (cursor → hermes subagent produces very different output) and makes debugging harder.
+
+### Adapter Hot-Reload
+
+Follows the existing `nerve.yaml` hot-reload mechanism. On config change, adapters are rebuilt. Running workflow threads are not affected (they use the `AdapterFn` bound at thread start). New threads automatically use the updated config.
+
+### WorkflowContext
+
+```ts
+type WorkflowContext = {
+  start: StartStep;
+  messages: WorkflowMessage[];
+  workdir: string;        // repo root — coding agent working directory
+  signal: AbortSignal;    // graceful cancellation
+};
+```
+
+`workdir` is required for coding agents. `signal` enables graceful cancellation of long-running agent calls — adapters must respect it (e.g. kill subprocess on abort).
+
+### Configuration Validation
+
+`nerve validate` checks:
+- All roles have a valid adapter function (not null/undefined)
+- Adapter CLIs are available (binary exists in PATH)
+- Extract provider is configured and reachable
+
+## Compatibility with Current Types
+
+The existing `Role<Meta>` signature:
+
+```ts
+type Role<Meta> = (start: StartStep, messages: WorkflowMessage[]) => Promise<RoleResult<Meta>>
+```
+
+remains the runtime interface. The new config layer is syntactic sugar — the runtime assembles `Role<Meta>` functions from `(adapter + prompt + schema)` instead of users writing them by hand. `WorkflowDefinition` stays the same at the engine level; `WorkflowSpec` is the new user-facing authoring format that compiles down to it at daemon startup / hot-reload time (runtime lazy compile, not `nerve init`).
+
+Existing hand-written `Role` functions continue to work — `WorkflowSpec` is additive, not a breaking change.
+
+## Knowledge Layer
+
+Project knowledge is a **built-in nerve feature**. Scope is the **repo** — each repo has its own knowledge base, tracked in git.
+
+### Architecture
+
+```
+Local (per repo)                         Remote Service
+┌───────────────────────┐           ┌─────────────────────┐
+│ knowledge.yaml        │           │ Embedding API       │
+│ ├── include/exclude   │   ──→     │ text → vector       │
+│ knowledge.db (SQLite) │   ←──     │ content-hash cache  │
+│ ├── chunk text        │           │ (avoid recompute)   │
+│ ├── embedding bytes   │           └─────────────────────┘
+│ └── cosine search     │
+└───────────────────────┘
+```
+
+- **Local-first** — `knowledge.db` stores chunks + embeddings, search runs locally (in-memory cosine similarity)
+- **Remote service only computes embeddings** — content-addressable cache keyed by text hash, avoids redundant computation across agents
+- **Branch-aware by design** — different agents on different branches naturally have different `knowledge.db` contents
+
+### Configuration (`knowledge.yaml` at repo root)
+
+```yaml
+include:
+  - "src/**/*.ts"
+  - "docs/**/*.md"
+  - "*.md"
+
+exclude:
+  - "node_modules/**"
+  - "dist/**"
+  - "*.test.ts"
+```
+
+`knowledge.yaml` is committed to git. `knowledge.db` is gitignored — it's a local cache rebuilt from source files + remote embedding service.
+
+### CLI
+
+```bash
+nerve knowledge sync              # index/re-index changed files
+nerve knowledge query "how does the signal bus work"
+
+# Scope
+nerve knowledge query "..." # default: cwd repo
+nerve knowledge query --repo /path/to/other/repo "..."
+nerve knowledge query -g "..."   # global search (all indexed repos)
+# --repo and -g are mutually exclusive
+```
+
+### Search Implementation
+
+Project-scale knowledge (hundreds to low thousands of chunks) does not need vector indices. Full scan with cosine similarity in memory is sufficient and adds zero native dependencies.
+
+```ts
+// Pseudocode
+const chunks = db.all("SELECT slug, chunk, embedding FROM chunks");
+const query_vec = await embed(query);
+const results = chunks
+  .map(c => ({ ...c, score: cosine(query_vec, c.embedding) }))
+  .sort((a, b) => b.score - a.score)
+  .slice(0, limit);
+```
+
+### Knowledge Layers
+
+```
+Project knowledge (knowledge.yaml)  Per repo, git managed, any agent reads
+Agent long-term memory              Per agent, domain expertise, cross-run
+Workflow context (start + msgs)     Per run, moderator-controlled history
+```
+
+## Open Questions
+
+1. **Agent long-term memory** — storage format and mechanism for persisting domain expertise across runs
+
+### Resolved
+
+- **Agent naming / registry** → removed; workflow roles declare adapter directly, no intermediate registry
+- **Extract override granularity** → two-level merge: global → role (agent level removed)
+- **Context threading** → `WorkflowContext` includes `workdir` and `signal` (see design above)
+- **Embedding service** → self-hosted, 1024-dim vectors, content-hash cache

+# RFC-004: Package Architecture — Shareable Workflows, Roles & Senses
+
+**Author:** 小橘 🍊（NEKO Team）
+**Status:** Draft
+**Created:** 2026-04-29
+
+## Summary
+
+Make workflows, roles, and senses publishable as lightweight npm packages. Workspaces become pure configuration — selecting packages, wiring adapters, and providing credentials. No builtin workflows in the nerve core.
+
+## Motivation
+
+Currently, workflows like `develop-sense` and `develop-workflow` live inside the workspace (`~/.uncaged-nerve/workflows/`). This creates problems:
+
+1. **No sharing** — every workspace duplicates the same workflow code
+2. **No versioning** — upgrading a workflow means manual file edits
+3. **Builtin is a trap** — if we bake workflows into nerve core, they require adapters and LLM providers that may not be installed. A fresh `nerve` install on a bare machine would fail to load builtins.
+4. **Roles are already shared** — `_shared/workspace-committer.ts` proves the pattern works; we just need to formalize it as packages
+
+The adapter pattern (`@uncaged/nerve-adapter-hermes`, `@uncaged/nerve-adapter-cursor`) already established the precedent: infrastructure as packages, workspace as wiring.
+
+## Design
+
+### Package Taxonomy
+
+```
+@uncaged/nerve-core              # types, engine
+@uncaged/nerve-daemon            # runtime
+@uncaged/nerve-workflow-utils    # createRole, decorateRole, withDryRun, onFail, etc.
+
+# Adapters (existing)
+@uncaged/nerve-adapter-hermes
+@uncaged/nerve-adapter-cursor
+
+# Workflows (new)
+@uncaged/nerve-workflow-solve-issue
+@uncaged/nerve-workflow-develop-sense
+@uncaged/nerve-workflow-develop-workflow
+
+# Shared Roles (new)
+@uncaged/nerve-role-committer    # workspace committer (branch, commit, push)
+@uncaged/nerve-role-reviewer     # code review role
+@uncaged/nerve-role-publisher    # PR creation role
+
+# Senses (existing pattern, formalized)
+@uncaged/nerve-sense-cpu-usage
+@uncaged/nerve-sense-disk-usage
+```
+
+### Package Contract
+
+Each package type exports a factory function:
+
+#### Workflow Package
+
+```ts
+// @uncaged/nerve-workflow-develop-sense
+import type { AgentFn, WorkflowDefinition } from "@uncaged/nerve-core";
+import type { LlmExtractorConfig } from "@uncaged/nerve-workflow-utils";
+
+export type SenseMeta = { /* ... */ };
+
+export type CreateDevelopSenseDeps = {
+  defaultAdapter: AgentFn;
+  adapters?: Partial<Record<keyof SenseMeta, AgentFn>>;
+  extract: LlmExtractorConfig;
+  cwd: string;
+};
+
+export function createDevelopSenseWorkflow(deps: CreateDevelopSenseDeps): WorkflowDefinition<SenseMeta>;
+```
+
+Key design decisions:
+- `defaultAdapter` + optional `adapters` override per role — via `Partial<Record<keyof Meta, AgentFn>>`
+- Adapter keys are derived from `Meta` type — adding/removing a role automatically updates the adapter map
+- Roles that don't need an agent simply don't appear in `adapters` (the `Partial` allows this)
+
+#### Role Package
+
+```ts
+// @uncaged/nerve-role-committer
+import type { AgentFn, Role } from "@uncaged/nerve-core";
+import type { LlmExtractorConfig } from "@uncaged/nerve-workflow-utils";
+import { createRole, decorateRole, withDryRun, onFail } from "@uncaged/nerve-workflow-utils";
+
+export type CommitterMeta = { committed: boolean };
+
+export function createCommitterRole(adapter: AgentFn, extract: LlmExtractorConfig): Role<CommitterMeta> {
+  const inner = createRole(adapter, prompt, committerMetaSchema, extract);
+  return decorateRole(inner, [
+    withDryRun({ label: "committer", meta: { committed: true } }),
+    onFail({ label: "committer", meta: { committed: false } }),
+  ]);
+}
+```
+
+Roles compose with the decorator chain from `workflow-utils`:
+- `withDryRun` — skip execution in dry-run mode
+- `onFail` — catch errors into structured failure results
+- `decorateRole(role, [...])` — apply decorators left-to-right
+- Custom `RoleDecorator<M>` can be created for project-specific needs
+
+#### Sense Package
+
+```ts
+// @uncaged/nerve-sense-cpu-usage
+export const senseName = "cpu-usage";
+export const schema = { /* drizzle schema */ };
+export async function compute(ctx: SenseContext): Promise<SenseResult>;
+```
+
+### Workspace as Configuration
+
+The workspace becomes a thin wiring layer:
+
+```
+~/.uncaged-nerve/
+  nerve.yaml           # senses, extract config
+  package.json         # depends on workflow/role/adapter packages
+  workflows/
+    develop-sense/
+      index.ts         # ~10 lines: import package, wire adapters, export
+    solve-issue/
+      index.ts         # same pattern
+```
+
+A typical `index.ts`:
+
+```ts
+import { createDevelopSenseWorkflow } from "@uncaged/nerve-workflow-develop-sense";
+import { hermesAdapter } from "@uncaged/nerve-adapter-hermes";
+import { cursorAdapter } from "@uncaged/nerve-adapter-cursor";
+
+export default createDevelopSenseWorkflow({
+  defaultAdapter: hermesAdapter,
+  adapters: { planner: cursorAdapter, coder: cursorAdapter },
+  extract: { provider: { apiKey, baseUrl, model } },
+  cwd: nerveRoot,
+});
+```
+
+### What Stays in Workspace
+
+- **Custom workflows** — project-specific workflows that aren't general enough to share
+- **Custom senses** — project-specific metrics
+- **Configuration** — adapter selection, credentials, `nerve.yaml`
+- **Overrides** — a workspace can always write its own role/workflow instead of using a package
+
+### Dependency Rules
+
+```
+nerve-core           ← no deps on other nerve packages
+nerve-workflow-utils ← depends on nerve-core
+nerve-adapter-*      ← depends on nerve-core
+nerve-role-*         ← depends on nerve-core, nerve-workflow-utils
+nerve-workflow-*     ← depends on nerve-core, nerve-workflow-utils, may depend on nerve-role-*
+nerve-sense-*        ← depends on nerve-core
+nerve-daemon         ← depends on nerve-core, nerve-store
+```
+
+Workflow packages depend on role packages (not adapters). Adapters are injected at the workspace level.
+
+### Migration Path
+
+1. **Phase 1: Extract role packages** — Start with `@uncaged/nerve-role-committer` (already `_shared/workspace-committer.ts`). Publish, update workspace to import from package.
+2. **Phase 2: Extract workflow packages** — Move `develop-sense` and `develop-workflow` to packages. Workspace `index.ts` becomes pure wiring.
+3. **Phase 3: Sense packages** — Formalize sense packaging (lower priority, senses are already self-contained directories).
+4. **Phase 4: Community** — Document the package contract so others can publish workflows/roles/senses.
+
+### Not in Scope
+
+- **No builtin workflows** — nerve core ships zero workflows. All workflows are packages installed by the workspace.
+- **No workflow marketplace/registry** — just npm packages. `pnpm add @uncaged/nerve-workflow-solve-issue`.
+- **No nerve.yaml workflow declaration** — workflows are still TypeScript entry points. The daemon discovers them the same way it does today.
+
+## Open Questions
+
+1. **Monorepo vs separate repos?** — Should workflow/role packages live in the nerve monorepo or separate repos? Monorepo is easier for coordinated releases; separate repos allow independent versioning.
+2. **Sense package format** — Senses currently bundle with esbuild. Should sense packages ship pre-bundled or as TypeScript source?
+3. **Version coupling** — How tightly should workflow packages pin `nerve-core`? Peer deps with semver range?
+
+## Prior Art
+
+- Adapter packages (`@uncaged/nerve-adapter-*`) — established the factory + injection pattern
+- `_shared/workspace-committer.ts` — proved roles can be shared across workflows
+- `createRole` / `decorateRole` / `withDryRun` / `onFail` in `workflow-utils` — building blocks that role packages compose
+- `defaultAdapter` + `Partial<Record<keyof Meta, AgentFn>>` pattern — adapter injection without coupling

+# Skill: Publish @uncaged/nerve packages to npm
+
+## When to use
+
+When releasing a new version of any `@uncaged/nerve-*` package to npm.
+
+## Prerequisites
+
+- npm login with an account that has **owner** access to the `@uncaged` org
+- All tests pass: `pnpm -r run test`
+- Clean working tree (no uncommitted changes)
+
+## Packages
+
+| Package | Path | npm |
+|---------|------|-----|
+| `@uncaged/nerve-core` | `packages/core` | [link](https://www.npmjs.com/package/@uncaged/nerve-core) |
+| `@uncaged/nerve-daemon` | `packages/daemon` | [link](https://www.npmjs.com/package/@uncaged/nerve-daemon) |
+| `@uncaged/nerve-cli` | `packages/cli` | [link](https://www.npmjs.com/package/@uncaged/nerve-cli) |
+
+## Dependency order
+
+`core` → `daemon` → `cli`
+
+Always publish in this order. If `core` has changes, bump and publish it first, then update dependents.
+
+## Steps
+
+### 1. Ensure clean state
+
+```bash
+git checkout main && git pull origin main
+pnpm install
+pnpm -r run build
+pnpm -r run test
+```
+
+### 2. Bump versions
+
+Manually update `version` in each changed package's `package.json`.
+
+Follow semver:
+- **patch** (0.1.x): bug fixes, refactors
+- **minor** (0.x.0): new features, non-breaking API additions
+- **major** (x.0.0): breaking changes
+
+If bumping `core`, also update the `@uncaged/nerve-core` dependency version in `daemon` and `cli` package.json. Same for `daemon` → `cli`.
+
+### 3. Build
+
+```bash
+pnpm -r run build
+```
+
+### 4. Publish (in order)
+
+```bash
+# Only publish packages that have version bumps
+# MUST use pnpm publish (not npm) — pnpm converts workspace:* to real versions
+cd packages/core && pnpm publish --access public --no-git-checks
+cd packages/daemon && pnpm publish --access public --no-git-checks
+cd packages/cli && pnpm publish --access public --no-git-checks
+```
+
+### 5. Commit & tag
+
+```bash
+git add -A
+git commit -m "release: @uncaged/nerve-core@X.Y.Z, @uncaged/nerve-daemon@X.Y.Z, @uncaged/nerve-cli@X.Y.Z"
+git tag -a vX.Y.Z -m "Release vX.Y.Z"
+git push origin main --tags
+```
+
+## Pitfalls
+
+- **Don't publish without building first** — `tsup` output in `dist/` is what npm ships
+- **Dependency order matters** — if you publish `daemon` before `core`, npm may resolve the old `core` version
+- **`--access public`** is required for scoped packages on first publish; safe to always include
+- **Check `npm whoami`** to confirm you're logged in as the right account
+- **No changeset tool** — this project uses manual version bumps (no changesets/lerna)

+# Skill: Setup nerve from scratch
+
+## When to use
+
+Setting up the nerve project for local development from a fresh clone.
+
+## Prerequisites
+
+- **Node.js** ≥ 18
+- **pnpm** ≥ 9 (`npm install -g pnpm`)
+- **Git** access to `git.shazhou.work`
+
+## Steps
+
+### 1. Clone
+
+```bash
+git clone https://git.shazhou.work/uncaged/nerve.git
+cd nerve
+```
+
+### 2. Install dependencies
+
+```bash
+pnpm install
+```
+
+This installs all workspace packages and links internal dependencies (`core` → `daemon` → `cli`).
+
+### 3. Build all packages
+
+```bash
+pnpm -r run build
+```
+
+Build order is handled automatically by pnpm workspace — `core` builds first, then `daemon`, then `cli`.
+
+### 4. Run tests
+
+```bash
+pnpm -r run test
+```
+
+Or test individual packages:
+
+```bash
+pnpm --filter @uncaged/nerve-core test
+pnpm --filter @uncaged/nerve-daemon test
+pnpm --filter @uncaged/nerve-cli test
+```
+
+### 5. Try the CLI
+
+```bash
+# Link the CLI globally
+cd packages/cli && npm link
+
+# Initialize a workspace
+mkdir ~/my-nerve-workspace && cd ~/my-nerve-workspace
+nerve init
+
+# Edit senses in nerve.yaml, then:
+nerve start      # start the daemon
+nerve sense list  # list registered senses
+nerve stop       # stop the daemon
+```
+
+### 6. Lint & format
+
+```bash
+pnpm run check    # biome lint check
+pnpm run format   # biome auto-format
+```
+
+## Project structure
+
+```

+└── biome.json      # linter/formatter config
+```
+
+## Key conventions
+
+- **Monorepo** with pnpm workspaces
+- **ESM only** — all packages output ESM (`"type": "module"`)
+- **tsup** for builds, **vitest** for tests, **biome** for lint/format
+- **SQLite** (better-sqlite3) for log store and blob store
+- See `docs/coding-conventions.md` for code style rules
+
+## Pitfalls
+
+- **Must build before test** — daemon and cli import compiled output from core
+- **better-sqlite3** requires native compilation — if `pnpm install` fails, ensure you have build tools (`build-essential` on Linux, Xcode CLI tools on macOS)
+- **Node 18+** required — uses native `fetch`, `crypto.randomUUID`, etc.
+- **pnpm only** — don't use npm/yarn, workspace links won't resolve correctly

+# @uncaged/nerve-cli
+
+Command-line interface for the [nerve](../../README.md) observation engine.
+
+## Install
+
+```bash
+pnpm add -g @uncaged/nerve-cli
+# or
+npx @uncaged/nerve-cli
+```
+
+Requires Node.js ≥ 22.5.
+
+## Commands
+
+### Workspace
+
+```bash
+nerve init                  # Initialize a nerve workspace (installs deps, scaffolds config)
+nerve validate              # Validate nerve.yaml configuration
+```
+
+### Daemon management
+
+```bash
+nerve daemon start          # Start the daemon (background)
+nerve daemon stop           # Stop the daemon
+nerve daemon status         # Show pid, uptime, sense names from nerve.yaml (process must exist)
+nerve daemon restart        # Stop then start
+nerve daemon logs           # Tail daemon process logs (file under workspace logs/)
+```
+
+### Development
+
+```bash
+nerve dev                   # Foreground kernel with file watcher + IPC (Ctrl+C stops)
+```
+
+### Querying & status
+
+```bash
+nerve logs                  # Tail or page the daemon text log file (path in footer; default ~/.uncaged-nerve/logs/nerve.log)
+nerve status                # Short daemon health summary (aliases daemon status)
+```
+
+Structured rows in `data/logs.db` are surfaced via **`nerve workflow inspect`** / **`nerve workflow list`** (and `LogStore` in code), not via `nerve logs`.
+
+### Sense
+
+```bash
+nerve sense list            # List senses (live fields from daemon IPC when running)
+nerve sense trigger <name>  # IPC trigger-sense — queue a compute for that sense
+nerve sense query <name>    # Read-only SQL on data/senses/<name>.db (optional SQL args)
+nerve sense schema <name>   # Print CREATE TABLE statements for that sense DB
+```
+
+### Store maintenance
+
+```bash
+nerve store archive         # Move old log rows to JSONL under data/archive/logs/… (optional --vacuum)
+```
+
+### Workflows
+
+```bash
+nerve workflow list         # Queued/started runs (add --all for terminal states; --workflow, --limit, --offset)
+nerve workflow inspect <runId>   # Run metadata + paginated workflow log lines
+nerve workflow thread <runId>    # Role rounds from persisted messages (--before, --budget)
+nerve workflow trigger <name>    # IPC trigger-workflow (daemon must be running)
+                                   # Optional JSON: --payload '{"prompt":"…","maxRounds":50}'
+```
+
+`nerve workflow trigger` sends a `trigger-workflow` line on the daemon Unix socket (same protocol as `@uncaged/nerve-core` / `parseDaemonIpcRequest`). It does not read `nerve.yaml` workflow definitions beyond what the running daemon already loaded.
+
+### Top-level aliases
+
+```bash
+nerve start    → nerve daemon start
+nerve stop     → nerve daemon stop
+nerve status   → nerve daemon status
+nerve logs     → nerve daemon logs
+```

+ * Shared E2E harness: temp HOME layout (`.uncaged-nerve`), real kernel + sense worker,
+ * IPC socket for CLI, and `runCommand` helpers with captured stdio.
+ *
+ * ## Signal persistence (CLI `nerve sense list`)
+ *
+ * The kernel appends a `source: "sense", type: "signal"` row to `data/logs.db` when a
+ * worker emits a signal (see `packages/daemon/src/kernel.ts`). The daemon also
+ * auto-persists each signal into a `_signals` table in the per-sense SQLite DB
+ * (see `runtime.persistSignal` in `packages/daemon/src/sense-runtime.ts`).
+ * `listSenses()` reads `lastSignalTimestamp` from the kernel's in-memory state,
+ * while `sense query` reads from the `_signals` table (or a user-defined preview table).
+ *
+ * ## Timeout guard (vitest)
+ *
+ * Always tear down the daemon in `afterEach` so a failed assertion does not leave a
+ * kernel and worker children running. Optionally race `stopTestDaemon` against a timer
+ * so CI does not hang if shutdown stalls:
+ *
+ * ```ts

+
+# Nerve Agent Skills
+
+**Agent Skills** are directories that contain a \`SKILL.md\` (with YAML frontmatter). Cursor loads them from **Project Skills** paths (for example \`.cursor/skills/\` or your global skills directory).
+
+## Getting Nerve-oriented skills
+
+There is no separate npm package for skills in the default workspace. To align with Nerve CLI, daemon, and monorepo conventions:
+
+1. Copy or symlink skill folders from the **Nerve** repository (e.g. \`packages/skills/*/\`) into \`.cursor/skills/\`, **or**
+2. Follow project documentation and \`CLAUDE.md\` / \`.cursor/rules/\` in this repo.
+
+## How to use in an agent
+
+1. When a task matches a skill’s **description** (in \`SKILL.md\` frontmatter), open that file and follow its steps.
+2. Prefer those conventions for sense/workflow layout, \`nerve.yaml\`, and tooling over generic guesses.
+3. Keep skills versioned with your dotfiles or project; update them when you upgrade Nerve.
