# v1.31 Closure Audit

Date: 2026-04-09
Status: pass

## Scope

This audit closes the current bounded `v1.31` milestone:

- source-fidelity grading
- reading-depth and assumption-quality seed
- citation/BibTeX/arXiv source-graph baseline signals
- analytic validation breadth beyond the first bare preset

## Evidence

Implemented surfaces:

- `L0` now exposes source-fidelity classes and citation-graph baseline signals
- `L1` now exposes `reading_depth` and `assumption_quality`
- `aitp verify --mode analytic` now exists
- analytic validation now carries explicit `analytic_check_families`
- `L4` runtime projections now surface analytic-check-family expectations

Regression evidence:

## Physicist-Facing Judgment

From the perspective of a theoretical physicist:

1. AITP now distinguishes stronger and weaker evidence bases instead of
   flattening them.
2. It now exposes whether a topic has only a preview-level understanding or a
   more technical reconstruction.
3. It now names analytic check families explicitly, which is much closer to how
   actual theory work is validated than a generic “please analyze” instruction.

## Limits

This closure still does not claim:

- collaborator memory,
- negative-result retention,
- low-bureaucracy exploration,
- or final reliability/UX closure.

Those remain downstream work.

## Verdict

`v1.31` is sufficiently implemented to close in GSD terms.
