[counterintuitive] Providing AI with the entire codebase context eliminates hallucination and logic errors

Provide AI with targeted, diff-level context and explicit interfaces, rather than dumping entire files, to force localized reasoning and prevent context dilution.

Journey Context:
There is a belief that more context equals better AI output. In reality, as context windows grow, AI suffers from 'lost in the middle' and context dilution, where it over-indexes on irrelevant distant code and loses focus on the immediate logic. Senior engineers intuitively focus on the diff and immediate call graph; AI needs explicit constraints to mimic this, or it hallucinates couplings that don't exist.
