# Memory - 2026-04-23## TILT Status Check (psb-thinking ran at 19:40 UTC)### Orange — Seltzer Base-4/26- Last reading: 4/23/2026 11:24 UTC- SG: 1.023, Temp: 74.7°F- Status: ACTIVE but stalled ~7 days at 1.023### Pink — 70megOhm- NO READINGS — TILT not transmitting- Spreadsheet: 1S8uSN_KeJXv6chtWq4xLIXLVJGYAVh1pZ9rAQa9EtQY- **Needs investigation:** is TILT powered on?### Green — HotForTeacher-4-26- Last reading: 4/6/2026 ~12:06 UTC (17 days ago!)- SG: 1.023, Temp: 69°F- Only transmitted for a few hours on April 6, then went silent- **Needs investigation:** TILT may be dead or have battery issue## Memory Fix (psb-thinking)- Gemma was stuck in heartbeat echo loop — saying HEARTBEAT_OK forever without loading context- Root cause: heartbeat prompt said "if nothing needs attention, reply HEARTBEAT_OK"- Gemma treated every 30m heartbeat as "nothing needs attention"- Fixed: HEARTBEAT.md now says do TILT check FIRST, then respond with actual status- Created SESSION-STATE.md for Gemma with TILT readings- Gemma should now do useful work on heartbeat instead of auto-replying## WAL Reminder- Every response: write to memory file FIRST, then do the work- This is Topher's #1 complaint — not technical memory failure, but WAL habit failure
