ADR-0087 exemption (no-migration-prescription): a CLI command's verdict on one edge, not a declaration: a no-write mode of os migrate value-shapes, os migrate recorded-by, os migrate resume, os secret orphans or os storage orphans pointed at a database that lacks a table it reads now exits 1 instead of creating the table and reporting nothing. No authorable key, spelling, export or stored shape moves: every stack parses and loads exactly as before, the write modes write exactly what they wrote before minus the seed loader's rows, and no stored row is read differently or rewritten. What an operator does about the refusal is point --database-url at the deployment's database or boot the deployment once, so there is no rewrite a ledger entry could carry. The other categories are closed on facts: both packages publish (not unpublished); no ADR-0087 id covers a command's verdict, and this diff adds none (not registered / already-registered); and the change is CLI behaviour plus one new optional runtime config key, not a TypeScript declaration change to an existing surface (not runtime-interface-only / type-surface-only).
