Reverts the interface_mode of sheet create and sheet export from composite back
to mcp with a single interface_ref, matching upstream/main and the existing
convention for multi-tool leaves (doc.create_document declares mcp +
create_document even though it also calls update_document).
Rationale:
- interface_ref is audit / traceability metadata; nothing reads it at runtime
(verified: rebuilding with a bogus interface_ref still routes to the correct
tool). Declaring the primary tool and treating the orchestration as an
implementation detail is the pattern main already uses.
- sheet export was mcp + submit_export_job on main; it already orchestrated
submit_export_job + query_export_job without declaring the poll. Adding an
--export-format csv branch does not change that shape, so it does not warrant
flipping to composite.
- sheet create was a genuine single-RPC command on main (create_workspace_sheet
only). The --values / --sheets / --styles orchestration I added runs after the
document exists; per the doc.create_document precedent it stays mcp.
This takes the sheet schema-compatibility failures from 4 to 0 without a waiver
or an admin override: the declarations now equal main's.
Also updates the wording of the seven new mapping-exclusion reasons for these
two commands (submit_export_job CSV params, create_workspace_sheet
values/sheets/styles) from "Composite ... input" to "Wrapper ... input", so the
reason text no longer collides with the interface_mode value now that both
leaves are mcp. The reasons are otherwise unchanged and still describe where
each value actually goes. range_batch_set_style keeps its "Composite" wording
because it genuinely stays interface_mode=composite.
Removes the two composite entries for these leaves from the interface
disposition contract test.
No execution path changes; targeted sheet suites, the disposition contract test,
and the schema-compat policy tests all pass; check-schema-catalog is green;
sheet-scoped schema-compatibility reports 0 failures.
