 - `src/deepgram/agent/v1/types/agent_v1settings_agent_context.py`, `src/deepgram/agent/v1/types/agent_v1settings_agent.py`, `src/deepgram/agent/v1/types/agent_v1settings.py`, `src/deepgram/agent/v1/requests/agent_v1settings_agent_context.py`, `src/deepgram/agent/v1/requests/agent_v1settings_agent.py`, `src/deepgram/agent/v1/requests/agent_v1settings.py` — backward-compat patches for the 2026-05-05 Agent Settings schema restructure. These preserve callable `AgentV1SettingsAgent(...)`, keep `AgentV1Settings.agent` accepting both that wrapper and `agent_id` strings, restore the legacy request TypedDict shapes, remap legacy `messages=[...]` / nested `context=AgentV1SettingsAgentContext(messages=[...])` usage into the new `context={"messages": [...]}` wire shape, and keep read-side `obj.messages` access working.
 - `src/deepgram/core/api_error.py`, `src/deepgram/core/parse_error.py` — credential redaction. Every websocket `connect()` path raises `ApiError(headers=dict(headers), ...)` with the full request headers, and both error types stringify that dict, so an unredacted `Authorization` reached `str(e)`, tracebacks, log aggregators and error trackers (which serialise attributes as well as the message). Both now mask credential values at construction via `_secure_logging.redact_sensitive_headers`, preserving non-sensitive headers (`dg-request-id`) for debugging. This is the same threat `_secure_logging.py` covers for the `websockets` DEBUG handshake logs, via the other path to it. Regression coverage in `tests/custom/test_api_error_redaction.py`. Unfreeze if the generator starts redacting credentials itself.
 - `src/deepgram/core/query_encoder.py` — coerces Python bools to lowercase `"true"`/`"false"` before they reach `urllib.parse.urlencode` (which would otherwise produce `"True"`/`"False"` via `str()` and break websocket query strings). Only the four `*/connect()` paths call `urlencode`; HTTP raw clients hand params to httpx, which lowercases bools itself, so the patch is a no-op for the HTTP path. Once Fern's websocket codegen normalizes bools (or the spec types these as `boolean` end-to-end), this can be unfrozen.
+- `src/deepgram/core/pydantic_utilities.py` — Pydantic 2.14+ makes mypy reject Fern's unannotated module-level `TypeAdapter` globals. Retain explicit `TypeAdapter[datetime]` / `TypeAdapter[date]` annotations until Fern emits them.
 - `src/deepgram/listen/v2/types/listen_v2connected.py`, `src/deepgram/listen/v2/types/listen_v2turn_info.py`, `src/deepgram/listen/v2/types/listen_v2turn_info_words_item.py`, `src/deepgram/listen/v2/types/listen_v2configure_success.py`, `src/deepgram/listen/v2/types/listen_v2configure_success_thresholds.py`, `src/deepgram/listen/v2/types/listen_v2configure_failure.py`, `src/deepgram/listen/v2/types/listen_v2fatal_error.py`, `src/deepgram/listen/v2/types/listen_v2warning.py` — read-side compatibility for the SDK 7.7 Listen V2 response retype. Through 7.6, `V2SocketClientResponse` contained `typing.Any`, so every response was returned as a raw dict; fixing the union made responses typed models and broke callers using `response["field"]`. These generated response classes inherit the hand-written base above, preserving read-only wire-key subscript access alongside canonical attribute access. Restore direct `UncheckedBaseModel` inheritance and unfreeze these files in the next major release.
 - `src/deepgram/types/deepgram_listen_provider_v2.py`, `src/deepgram/agent/v1/types/agent_v1settings_agent_listen_provider.py`, `src/deepgram/agent/v1/types/agent_v1settings_agent_context_listen_provider.py` — behavioural back-compat shim for the `language_hint` -> `language_hints` rename (2026-06-15 regen). The public field was historically (incorrectly) singular and accepted a str or a list; the API field is `language_hints` (a list, and the server uses `deny_unknown_fields` so the singular key is rejected on the wire). Each carries a hand-added `model_validator(mode='before')` / `root_validator(pre=True)` that remaps a legacy `language_hint=` kwarg and drops the dead singular key. Remove and unfreeze the language alias when it is retired in a future major.
 - `src/deepgram/types/shared_topics.py`, `src/deepgram/types/shared_intents.py`, `src/deepgram/requests/shared_topics.py`, `src/deepgram/requests/shared_intents.py`, and the generated root/type/request barrels — direct Topics and Intents segments plus their generated exports remain Fern-owned, but carry the v7 deprecated `results` construction facade and Params shape for the hand-written wrappers above. The models normalize legacy `results.{topics,intents}.segments` input to direct `segments` while preserving direct fields and deprecated read facades. Freeze these generated files during the parent reconciliation; retain all direct generated segments and exports alongside the compatibility surface.
