Add Materios partner chain integration and expand hotwords

Support two anchoring paths: direct Cardano L1 via managed API and
Materios partner chain with committee certification and batched L1
anchoring. User selects path via voice at runtime.

 ## What It Does
 
-Creates tamper-proof, blockchain-anchored audit trails for AI conversations using Orynq Proof-of-Inference protocol. Each message is hashed into a rolling SHA-256 chain and anchored to Cardano L1 (metadata label 2222) for independent verification.

 ## Setup

+3. For Materios support: get a gateway API key and replace `YOUR_MATERIOS_GATEWAY_API_KEY_HERE`
+4. Upload the ability to your OpenHome dashboard
 
 ## How It Works
 
-1. You trigger the ability with a phrase like "audit my AI"
-2. Speak the messages you want included in the audit trail
-3. Say "done" when finished
-4. The ability builds a SHA-256 rolling hash chain where each entry links to the previous one
-5. The chain is submitted to Orynq API for anchoring to Cardano L1
-6. You receive a transaction hash for independent verification

+
+### Direct Cardano Path
+- Hash chain is submitted to the Orynq managed API
+- Anchored directly to Cardano L1 under metadata label 2222
+- You receive a transaction hash for on-chain verification
+
+### Materios Partner Chain Path
+- Trace data is uploaded as blobs to the Materios gateway
+- A receipt is submitted on-chain to the Materios Substrate chain
+- The cert daemon committee attests data availability
+- Certified receipts are batched into Cardano L1 anchors automatically
+- You receive a receipt ID for tracking through the full lifecycle
 
 The hash chain is tamper-proof: changing any single entry invalidates all subsequent hashes, making unauthorized modifications detectable.
 
 ## Example Conversation
 
-> **User:** "Audit my AI"
-> **AI:** "I will create a blockchain audit trail for this conversation. Each message gets hashed into a tamper-proof chain anchored to Cardano."
+### Direct Cardano
+
+> **User:** "Anchor this session"
+> **AI:** "I will create a blockchain audit trail. Would you like to anchor directly to Cardano, or use the Materios partner chain for high-throughput certified receipts?"
+> **User:** "Direct to Cardano"
+> **AI:** "Using direct Cardano anchoring via the managed API. Tell me what to include in the audit trail."
 > **User:** "Log that the model recommended treatment plan A for patient 42"
-> **AI:** "Got it. I will include your messages in the audit trail. Say more to add entries, or say done when finished."
-> **User:** "The confidence score was 0.94 with no flagged biases"
-> **AI:** "Added. 2 messages in the trail so far. Say done to finalize."
+> **AI:** "Got it. Say more to add entries, or say done when finished."
+> **User:** "Done"
+> **AI:** "Your 1-entry audit trail has been anchored to Cardano and is now tamper-proof and independently verifiable."
+
+### Materios Partner Chain
+
+> **User:** "Run orynq"
+> **AI:** "I will create a blockchain audit trail. Would you like to anchor directly to Cardano, or use the Materios partner chain?"
+> **User:** "Use Materios"
+> **AI:** "Using Materios partner chain. Your receipt will be certified by the committee and then batched into a Cardano L1 anchor. Tell me what to include."
+> **User:** "The agent processed 500 claims with a 98.2% accuracy rate"
+> **AI:** "Got it. Say more to add entries, or say done when finished."
 > **User:** "Done"
-> **AI:** "Your 2-entry audit trail has been anchored to Cardano. It is now tamper-proof and independently verifiable."
+> **AI:** "Your audit trail was submitted to Materios. The cert daemon committee will verify, then it gets batched into a Cardano L1 anchor automatically."
