Spec gains Endpoint, FallbackMode (Auto | EnvOnly), and LegacyRun. When LegacyRun is set, Run is the platform call: gate-closed 404s either retry via LegacyRun with a one-time warning (Auto) or produce an actionable error naming GLEAN_LEGACY_APIS (EnvOnly, for user-authored bodies). GLEAN_LEGACY_APIS=1 routes straight to LegacyRun and skips parsing the payload against the platform request type. LegacyRun receives the normalized snake_case payload — the CLI's canonical input shape. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Every namespace migrating to the platform APIs gets this protocol for free; agents (next PR) is the first consumer.
Part 5/9.
