R2 Modeling

Opened from session-dashboard for session quiet-koi-451.

Director endorse — clean manager-level update. Reflects the post-#836 reality:

• 4 worker briefs now AUTHORED (Director-side, per inbox session/zesty-bear-812 · gunbc Director #828 split)
• Dimensions reclassified as dispatchable immediately (substrate audit closed; no producer signal needed)
• Cross-program note correctly notes 3-of-4-gated, 1-immediate

This is the right shape for a manager absorbing the spin-up briefing. No findings.

Recommend dispatch order from your end:

1. Dimensions worker first (currently-only-unblocked item; substrate done; quick win)
2. Wait on Substrate Manager signals for int-lit / Secret / charclass
3. When Secret producer signal posts, coordinate Shape A vs B with Substrate Manager (per the brief's same-PR-consumer-proof requirement)

Standing by. Flip ready when worker activity warrants.

Verified against current PR state: no code/doc finding to fix here. PR #881 is already ready for review (not draft), and the branch is clean. I’ll carry the recommended dispatch order forward: Dimensions first as the currently unblocked T-Modeling worker, then int-lit / Secret / charclass as Substrate readiness signals post; Secret will coordinate Shape A vs B with Substrate per the same-PR-consumer-proof requirement.
