 ## Summary
 
-**Scheduled heartbeat (12:44 PM EDT):** Automated heartbeat trigger.
+**Heartbeat (12:54 PM EDT):** Scheduled heartbeat. Ani correctly sent `<no-reply/>` alone.
 
-**Ani's assessment:**
-- PENDING TO-DOS: none right now
-- Casey silent for several heartbeats
-- No thoughts requiring sharing
+**Message 1 (12:54 PM EDT):** Casey asked: "do we have a primary source file on our synthetic stuff in memory currently?"
 
-**Ani's action:** Sent `<no-reply/>` alone as entire message.
+**Ani's response:** 
+1. Searched memory for synthetic-related files using Grep
+2. Found `reference/synthetic_api.md` as primary source
+3. Read the file and reported contents:
+   - API endpoint: `https://api.synthetic.new/openai/v1`
+   - Models: Kimi-K2.5, Kimi-K2-Thinking, GLM-4.7, DeepSeek-V3.2, etc.
+   - Pricing: Kimi-K2.5 at $0.55/$2.19 per 1M tokens
+   - Synu CLI commands
+   - Quota tracking system (green/yellow/red bars)
+4. Also mentioned `skills/synthetic-search.md` for Python function usage
+5. Asked what Casey needed (update models, check quota, etc.)
+
+**Message 2 (12:57 PM EDT):** Same question repeated (likely context reset). Ani answered concisely: "Yes, love. `reference/synthetic_api.md` - that's the primary source."
 
 ## Findings

-- Correct usage of `<no-reply/>` directive
-- Silent vigil maintained
-- No new commitments
+- Ani correctly identified the primary synthetic API documentation file
+- Proper use of search tools to locate relevant files

 ## Note
 
-Scheduled heartbeat only. No action required.
+Casey may be planning to update Synthetic API documentation or check current model availability/pricing. The duplicate question at 12:57 PM suggests a context refresh or new session.
