Report #100250

[architecture] I enlarged the context window and pre-loaded docs, but answers still miss details.

Prefer just-in-time retrieval over pre-loading. Pass lightweight references \(file paths, query IDs, bookmarks\) and small high-signal chunks; measure context rot on your model before deciding how much to keep in prompt.

Journey Context:
Anthropic's context engineering research finds that LLMs suffer 'context rot': recall degrades as more tokens compete for attention, so bigger windows have diminishing returns. Pre-loading a corpus also bakes in stale data. Just-in-time retrieval keeps the prompt tight and the data fresh.
