Precon Sizing System
Summary
The precon sizing system derives early commercial understanding from the published project corpus.
Problem
Sizing needs more than a document download. It requires selected evidence, indexing, assumptions, snapshots, quality checks, and repair paths when the corpus is incomplete.
Principle
Treat sizing as a replayable operational product with snapshots, not as a one-off LLM answer.
Platform Shape
Sizing services and preview/benchmark jobs build and evaluate opportunity sizing outputs. Benchmark documentation records quality progress and preserves the rationale for the current sizing phase.
