SEC-KN-P6-VERIFY: SESSION_SECRET share VERIFIED-SHARED (Outcome B)

Evidence-only session. Signed-token cross-acceptance probe: one gateway-signed agent_access JWT is accepted by GET /api/v1/auth/session on both the Netlify gateway (api.knowtation.store) and the distinct EC2 MCP host (mcp.knowtation.store, nginx/Node, own CORS); garbage/no-auth return 401 there. HS256 verify succeeds iff the secret is identical -> secret is SHARED.

Per the frozen instruction, no fix improvised. Opened SEC-KN-P6-ROTATE (Thinking) to freeze a rotate/split; top freeze input is whether the EC2 MCP host runs pre-SEC-KN-3 code (UNVERIFIED, not probed - would need active elevation attempt).

Optional sidecar CONFIRMED: created_by populated on the 7 newest (post-SEC-KN-4) proposals incl. prop-1785500300353491755; older 57 empty by design.

Governance sync (SD-17): docs/ROADMAP.md gate + rows, docs/OVERSEER-HANDOVER.md NEXT regenerated, evidence doc docs/reviews/2026-08-01-sec-kn-p6-verify-session-secret-share.md. Read-only; no posture/env flip; no rotation; no deploy. F7 AWS-parked.
