# Phase 70 Summary

Status: implemented on `main`

## Goal

Make analytical validation into a first-class production mode instead of
folding analytical work into the generic `hybrid` bucket.

## What Landed

- `verify --mode analytical` is now accepted through the public CLI
- `AITPService.prepare_verification(mode="analytical")` now materializes an
  analytical validation contract with limiting-case, dimensional, symmetry, and
  consistency checks
- `theory_synthesis` now defaults to `analytical` validation instead of
  `hybrid`
- topic shell materialization now preserves that analytical default through
  runtime validation contracts

## Outcome

Phase `70` is complete.
The next active milestone step is Phase `71`
`analytical-review-artifacts-and-runtime-surfaces`.
