The 7-doc package is accepted as a good narrow schema-binding analysis for the current blocker. It correctly identifies that the deployed production schema is the contract, the in-memory abstract ledger shape must be rebound, no production schema migration is currently required, and a new code-authoring cycle will be needed.

However, User has now imposed a stronger strategic requirement: the system must scale to hundreds of thousands and later millions of information units, avoid hardcoding in any form, maximize automation, and treat SQL as the source of truth while using NoSQL/vector only as flexible/search acceleration. The current package does not yet fully answer that mandate.

Therefore code authoring remains blocked pending r2 expansion.

Missing / Required r2 Expansion

The current package contains 7 documents. It lacks the two explicit mandate documents required by GPT/User:

missing_required_documents:
  - dot-iu-cutter-v0.4-scale-automation-nonhardcode-review-2026-05-17.md
  - dot-iu-cutter-v0.4-sql-nosql-hybrid-information-unit-strategy-2026-05-17.md

Additionally, the final report must be updated to incorporate their conclusions.

Required r2 Scope

Agent must author a design r2 / addendum, not code.

Required outputs:
