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.
Ground-truth pass over the named flagship consumer (portfolio-optimiser's
'OKF-upload-inbox') found it does not exist as a seam: both optimiser siblings
are frozen at release, carry their own OKF layer, receive no external bundles,
and take no dependency on this guard. Defer consumer integration (stream 2)
until the guard is mature; mature it here first, Node-port-friendly. Next
concrete build is the in-repo OKF inbox showcase (mode-b import_bundle as a
receive/quarantine gate), spec'd under 'The OKF inbox showcase'.
One realistic content sample carrying many vulnerabilities at once, run through
a mock ingestion pipeline (sanitize -> lexicon+entropy+decode-rescan -> output
gate -> disposition); assert every planted vuln is caught and disposition fails
secure. Doubles as the README worked example. Added to build-order step 11 and
the test strategy; tracked as task #11. Inspiration: llm-security/examples/*.
