v0.3.0 — Evidence-gated P0

Evidence-gated query and sharing

• Persisted claim provenance now validates original raw SHA-256 before citations are eligible.
• Queries with no usable evidence abstain deterministically without invoking an LLM.
• SSE responses are verified before display and clearly labelled as verified-buffered.
• Guided doctor profiles provide Demo, Personal-private, and Share-ready next steps without mutating personal data.
• Public sharing is explicit and fail-closed: canonical policy, local security overlay, typed approval, redacted manifest, and recoverable publication receipt.

Validation

• 604 passed, 6 skipped locally.
• Clean-room E2E covered guided onboarding, wiki HTTP read-only endpoints, provenance abstention, and share block/allow paths.
• GitHub Actions CI passed on PR #2.
• Three target-user personas scored 94, 96, and 95 out of 100.
