Same pattern as B.6 / B.7: OAuthDeviceLookupApi moves to
controllers/openapi/oauth_device/lookup.py and is re-registered on
service_api_ns to keep /v1/oauth/device/lookup serving until Phase F.
service_api/oauth.py is now down to /me + /oauth/authorizations/self
plus three legacy mounts; remaining handlers move in Phase C.
Now-unused imports (LIMIT_LOOKUP_PUBLIC, rate_limit, reqparse, request,
DEVICE_FLOW_TTL_SECONDS, DeviceFlowRedis, DeviceFlowStatus) removed.
Plan: docs/superpowers/plans/2026-04-26-openapi-migration.md (in difyctl repo).
Same pattern as B.6: OAuthDeviceTokenApi moves to
controllers/openapi/oauth_device/token.py and is re-registered on
service_api_ns to keep /v1/oauth/device/token serving until Phase F.
_audit_cross_ip_if_needed helper moves with the handler. Now-unused
imports removed from service_api/oauth.py.
Plan: docs/superpowers/plans/2026-04-26-openapi-migration.md (in difyctl repo).
Canonical class OAuthDeviceCodeApi now lives in
controllers/openapi/oauth_device/code.py and is registered on
openapi_ns at /openapi/v1/oauth/device/code. service_api/oauth.py
re-registers the same class object on service_api_ns at
/v1/oauth/device/code so existing callers keep working until Phase F.
KNOWN_CLIENT_IDS literal moves to dify_config.OPENAPI_KNOWN_CLIENT_IDS
(CSV-parsed, default "difyctl") so new CLIs / SDKs can be admitted
without code changes (CLAUDE.md rule 8 — no magic strings).
_verification_uri helper moves with the handler. Single source of
truth — no duplicated logic between the two mounts.
Plan: docs/superpowers/plans/2026-04-26-openapi-migration.md (in difyctl repo).
