ADR-0087 exemption (no-migration-prescription): a narrowing of what stays loaded at boot: a flow whose registration the kernel:ready cold-boot bind refuses is now withdrawn instead of staying registered from the boot pull. What is refused is unchanged, it is the same refusal registerFlow already made; only its outcome at boot changes. No authorable key, spelling, export or stored shape moves: FlowSchema and every node schema parse exactly what they parsed, the package exports the same names with the same types, no stored row is read or rewritten, and which value an author meant is not something a ledger entry can rewrite. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers this rule and this diff adds none (not registered or already-registered); and the change narrows what boot keeps registered, not a runtime interface or a type surface alone (not runtime-interface-only or type-surface-only).
