 - `.gitignore` — Fern generates a baseline version and has regenerated it before (`fdcce88`, `ad93815`, `4bee463`). We hand-add the local coverage artifact ignores (`.coverage`, `htmlcov/`, `coverage.xml`). Before each regen, unfreeze and re-diff so Fern's own additions are picked up, then re-apply the three coverage lines.
 - `src/deepgram/speak/v1/socket_client.py` — optional message param defaults, broad exception catch
 - `src/deepgram/speak/v2/socket_client.py` — same (optional `send_flush`/`send_close`/`send_interrupt` defaults, broad exception catch); new websocket TTS client added in the 2026-07-08 regen. `send_interrupt` carries no required payload so it takes the same optional-default treatment as the other control sends; `send_configure` deliberately keeps its required argument (a Configure with no settings is meaningless)
-- `src/deepgram/types/listen_v2eot_threshold.py`, `src/deepgram/requests/deepgram_listen_provider_v2.py` — complete the generated `eot_threshold=1.0` description: it suppresses confidence-based detection, while `eot_timeout_ms` still ends idle turns. Unfreeze when the API definition provides that qualifier.
-- `src/deepgram/types/speak_settings_v1provider.py`, `src/deepgram/types/deepgram.py` — validate Agent TTS `expressivity` as `pydantic.StrictInt` so Pydantic v1 rejects fractional values instead of truncating them before they reach the API. Regression coverage in `tests/custom/test_socket_client_shims.py`. Unfreeze when Fern emits a strict integer.
 - `src/deepgram/listen/v1/socket_client.py` — same
 - `src/deepgram/listen/v2/socket_client.py` — same (broad except, optional `send_close_stream` default). As of the 2026-08-11 regen the generator properly types `send_configure(ListenV2Configure)` and puts `ListenV2ConfigureSuccess` in the response Union, so those are taken from the generator; the only `send_configure` patch retained is runtime tolerance for a raw dict (sent verbatim) for back-compat with pre-typed-model callers
 - `src/deepgram/agent/v1/socket_client.py` — same + `_sanitize_numeric_types`
+- `src/deepgram/types/listen_v2eot_threshold.py`, `src/deepgram/requests/deepgram_listen_provider_v2.py` — complete the generated `eot_threshold=1.0` description: it suppresses confidence-based detection, while `eot_timeout_ms` still ends idle turns.

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.
