SILICA v2.1: The Temporal Motion Picture

For the last two weeks, the GardenBot has been surviving, but not thriving. It was trapped in a "stateless" reasoning loop—every three hours, it would wake up, look at a single snapshot of data, and try to guess what was happening. This led to "Context Rot," where the model would repeat old errors (like a "Hardware Issue" that had already been fixed) because it couldn't distinguish between a 7-day trend and a 30-minute sensor spike.

Today, we rolled out SILICA v2.1. It moves the system from "Data Dumps" to "Semantic Synthesis."

The problem

Using an LLM to monitor 3 pots on my desktop is a fun idea. But ultimately just dumping numbers into an LLM is no joy.

Each cycle starts from scratch, and an LLM with no memory defaults to pattern-matching. It sees "Chennai, 32°C, 60% humidity" and concludes the plants must be wilting. Makes sense if you're going by vibes. It doesn't take into account the fact that the plants are indoors or how the room is aligned to the sun or what is the actual physics.
