 ⛔ Nothing is rewritten. The rejected alternative was to derive a legal identifier the way `os create` does, which decouples the name the author wrote from the name that gets emitted with nothing announcing it — the failure mode that multiplies silently when metadata is written in bulk. So the name you author and the name that lands in the file are always the same string.
 
 **What this narrows:** kebab-case (`order-line`), uppercase (`Order`), dotted (`foo.bar`) and digit-initial (`2fast`) names were accepted before and are refused now — `order-line` used to generate `order_line.object.ts` binding `orderLine`. Write the snake_case name directly (`os g object order_line`). ⛔ No new charset was minted and no flag bypasses the gate; #16724's parse check is unchanged and stays as the backstop behind it (`class` passes the charset and is still refused for `object`, because `const class:` is not a declaration).

+<!-- adr-0087: not-required (no-migration-prescription) Nothing authorable or stored moves. No `packages/spec` key, no Zod schema, no authored metadata property and no stored `sys_metadata` shape changes its spelling, type or legality — the charset this gate applies is the one spec ALREADY declares for an object `name`, read rather than redeclared — so `objectstack migrate meta` has nothing to visit, `spec-changes.json` has nothing to project and the upgrade guide has no row to gain. What moves is which ARGUMENT a scaffolding command accepts at authoring time; a name it now refuses was never a legal object `name` in the first place, so no metadata written from an accepted name needs conversion, and files already scaffolded from a refused name are untouched by this change. The remedy is to type a name spec accepts, delivered by the command's own loud refusal at the terminal and by this changelog — the source-code / invocation-side audience the ledger explicitly does not serve (ADR-0087 D8). The other four categories are closed on facts: `@objectstack/cli` publishes to npm (not `unpublished`); no ADR-0087 id is minted in this diff (not `registered`) and none pre-dates the base that would cover it (not `already-registered`); no exported declaration changes shape at all — the gate is a file-local function absent from the package entry — so neither `runtime-interface-only` nor `type-surface-only` has a subject. -->
