Tracks registry decision D-J under #43. The charter's stated default is evidence to test, not a decision already taken. Explicit owner GO is required.
Decision question
Is the engine's canonical durable contract the in-memory model plus operation vocabulary, with binary storage/interchange owned by hosts and supported by engine conversion/packing tooling, or does the engine itself own a durable binary format?
Decision time
At the Phase 5 boundary, together with D-G(b), after real .grida→n0 converter experience and the n0 XML ratification pass.
Evidence bar
- Converter evidence over the pinned real-document corpus: what preserves, rejects, or needs host policy.
- The ratified n0 XML contract and its authored-source/resource boundaries.
- A responsibility matrix for schema/version ownership, unknown-field policy, resource packaging, validation, upgrades, compatibility support, and test ownership under each stewardship option.
- At least one concrete host-integration sketch, plus the engine tooling/API surface each option requires.
Guardrails
- Keep D-J distinct from D-G(b): stewardship and representation are coupled, not identical.
- Do not modify
format/grida.fbs, make .grida native to the chassis, or serialize resolved documents.
- Do not claim host management is free; required tooling and compatibility ownership must be priced.
Context
Done
The converter findings, ratification result, and responsibility matrix are linked; owner GO is recorded; one steward exists for every compatibility obligation; D-G(b) is reconciled without collapsing the two questions; and the verdict is recorded in the charter and #43.
