Review follow-up. The per-group secret validators normalised a hand-picked list of API keys, which left other optional credentials and overrides (OPEN_ROUTER_API_KEY, S3 and Daytona keys, ELASTIC_PASSWORD, the OIDC trio, connector client ids, MICROSOFT_AUTHORITY, MCP_OAUTH_REDIRECT_URI) holding the literal "None" or "" a .env file spells "unset" with, so truthiness checks and fallbacks downstream saw a value. One rule on the group base replaces those lists: every Optional[str] field maps "", "None" and whitespace to None and strips real values. Plain str fields are left alone. The OIDC required-settings check therefore also rejects those spellings. EMBEDDINGS_POOLING is Literal["cls", "mean"] with case-insensitive parsing; its consumer silently ignored anything else. Bounds added where the consumer rejects or misbehaves on the value: SCHEDULE_RUN_OUTPUT_RETENTION_DAYS and MESSAGE_EVENTS_RETENTION_DAYS (the cleanup repositories raise on <= 0), EMBEDDINGS_DELEGATE_TIMEOUT, the remote-device idle/pairing/invocation TTLs and CELERY_VISIBILITY_TIMEOUT (> 0), REMOTE_DEVICE_CMD_QUEUE_TTL_SECONDS (> 605, the documented drain deadline), GRAPHRAG_MAX_CHUNKS_FOR_EXTRACTION (>= 0; negative would slice the pending list from the end). The generated reference now renders generic type arguments (dict[str, int] rather than dict).
