Roadmap update 2026-09-29: Gate A owner, F-2W-3 done, measured paper accounts, user-only list corrected

[seathatflowsinourveins]

Summary

Adds a dated ## Updates section to docs/decisions/2026-09-28-ecosystem-roadmap.md (#469). The earlier text is unchanged.

• Gate A owner: native-agent-stack-2d takes F-NOW-1 and F-NOW-2. This is quoted as that peer stated it; delegated-decisions.md is not edited.
• The user's order, as relayed by 2d: prove the token stack E2E first, then run the full waves.
• F-2W-3 is done: lane_packets --manifest-newcomers: carry a discovery refuted only by a missing vote (F-2W-3) #471.
• Measured paper-account state: read-only, counts only.
• User-only list corrections that follow: only the IBKR 2FA, Mac consent, purchases or custody, and the Mac trial-C account check remain the user's.
• The trading lane is still unowned, and Paper engine: replay fills in execution order per symbol, never into a short (#355 follow-up) — Claude review pending #362's no-paper-unit condition is met.
• Pointer to the post-merge corrections on Roadmap record 2026-09-28: current architecture, recorded targets, gaps and next moves #469.
