- Single-source registry: oauth clientId/tokenUrl, usage URLs, image/embed configs, search defaultModel, codex fixedPort, google token url derive. - Remove 29 unused OmniRoute providers (registry 100→71); media intact. - De-adhoc: codex literals → registry format/oauth flags; reasoningInject, image/embed openrouter headers + xai bodyFields config-driven. - Add REGISTRY_TEMPLATE.js + expand PROVIDER_DEFAULTS/schema JSDoc. - Baselines updated; PROVIDERS 62 + alias 90 byte-for-byte, golden snapshots.
