AI Posture v1.0.0

First stable release. The specification is promoted to v1.0.0, locking the three-vector set (People, Infrastructure, Regulation). This is a stability declaration only. No scoring, likelihood, prior, or aggregation changes.

Highlights

• Spec, product, site, and agent surfaces aligned to v1.0.0.
• Legal copy finalized. Beta notices removed, effective 2026-05-29.
• Analytics QA closed. Memory-only PostHog, no PII in event payloads.
• Historical pre-assessment PRD archived. ROADMAP.md is the source of truth for remaining work.
• New Papers section: the whitepaper "One Number You Can Defend" with PDF, video summary, and audio overview, plus an executive-brief companion linking to PAICE.foundation.
• Release-hygiene and papers test suites added. 61 tests, all green.
