-# OpenClaw Interaction Evidence
+# OpenClaw Activity Records
 
-Capture OpenClaw tool calls as signed PEAC interaction evidence receipts.
-
-## Install
-
-```bash
-pnpm add @peac/adapter-openclaw @peac/capture-core
-```
+Capture OpenClaw tool calls as offline-verifiable activity records with durable file-based storage and real signing.
 
 ## Run
 
 ```bash
-pnpm demo
+# From monorepo root
+pnpm -C examples/openclaw-capture demo
 ```
 
 ## What it does
 
-1. Creates a capture session with in-memory storage
-2. Captures three simulated OpenClaw tool call events (web_search, file_read, code_execute)
-3. Verifies tamper-evident chain integrity (each entry links to the previous via digest)
-4. Emits signed receipts via the background service
-5. Prints receipt summaries with interaction IDs and JWS tokens
+1. Generates a signing key (to a temp directory)
+2. Activates the evidence export plugin with durable file-based storage
+3. Captures 3 simulated tool call events (web_search, file_read, code_execute)
+4. Exports an evidence bundle (manifest.json + signed receipts)
+5. Verifies the bundle offline
 
 ## Requirements
 
-- Node.js 20+
+- Node.js 22+
 - pnpm 8+
-
-## Caveats
-
-- The demo signer produces a structurally valid but **not cryptographically signed** JWS.
-  For real signing, use an Ed25519 key via `@peac/crypto` or a standard JOSE library.
-- In-memory stores are inlined in the demo. In production, use a durable store
-  (filesystem, database, etc).
-
-## Using this outside the PEAC monorepo
-
-This example uses `workspace:*` dependencies for monorepo development.
-To run it standalone:
-
-```bash
-mkdir openclaw-demo && cd openclaw-demo
-npm init -y
-pnpm add @peac/adapter-openclaw@0.10.9 @peac/capture-core@0.10.9
-pnpm add -D @types/node tsx typescript
-```
-
-Then copy `demo.ts` and `tsconfig.json` into the directory and run `npx tsx demo.ts`.
+- Run from the monorepo root (uses `workspace:*` dependencies)
 
 ## Expected output
 
 ```
-OpenClaw Interaction Evidence Demo
-
-1. Creating capture session...
-   Session ready.
+1. Generating signing key...
+   kid: <key-id>
 
-2. Capturing tool calls...
-   Captured: web_search -> digest a1b2c3d4...
-   Captured: file_read -> digest f7e8d9c0...
-   Captured: code_execute -> digest 1234abcd...
+2. Activating plugin...
+   Plugin active.
 
-3. Verifying chain integrity...
-   Chain OK: 3 entries, all linked
+3. Capturing tool calls...
+   web_search: captured
+   file_read: captured
+   code_execute: captured
 
-4. Emitting signed receipts...
-   Emitted 3 receipts
+4. Flushing receipts...
+   Receipts signed and written.
 
-5. Receipt summary:
-   - r_<digest>
-     interaction_id: openclaw/cnVuX2RlbW8/Y2FsbF8wMDE
-     jws: eyJhbGciOiJFZERTQSJ9...
+5. Exporting evidence bundle...
+   Exported 3 receipts.
 
-Done. All tool calls captured as verifiable interaction evidence.
-```
-
-## Two-stage pipeline
+6. Verifying bundle...
 
+verification successful -- 3 receipts in evidence bundle
 ```
-Tool Call        Spool             Receipts
-(sync hook) --> (append-only)  --> (signed JWS)
-< 10ms          events.jsonl       *.peac.json
-```
-
-- **Capture stage**: Maps OpenClaw events to CapturedAction, hashes payloads inline
-- **Emit stage**: Drains spool, converts to InteractionEvidence, signs with Ed25519
