Replace the unverified/absolute novelty statement with the defensible
four-part-contract form, verified against a focused adversarial PyPI+GitHub
survey (2026-07-15):
- BRIEF §11: 'assumed, not verified' -> verified survey with sources. Names
aig-guardian (real, query-time; blurs only the minimal-dep-library
differentiator), GuardLLM (nearest neighbour, runtime hardening, no
scan-before-persist / capability isolation / fail-secure), and ipi-scanner
(orphaned placeholder repo, recorded for honesty not as prior art).
- README: differentiator moved from 'library vs hosted/model' to the full
four-part write-time contract.
- PLAN §27-31: drop the unverifiable 'the first' superlative.
Also promotes the v1.0 session plan (PLAN-v1.md) and the cross-model review
(review-2026-07.md) into docs/ on the open/ mirror, referenced by PLAN.md's
re-sequencing addendum.
