Same shape of fix we applied to anthropic_adapter.py earlier — these
adapters do dict-style mutation on values typed as
ChatCompletionMessageParam (a union of TypedDicts) or against Optional
fields. Apply boundary casts (`cast(dict[str, Any], ...)` for the
mutation block, cast back to the TypedDict at return sites). Most
changes are pure typing (rename + cast); a handful in gemini and
openai_realtime are small defensive bug fixes for code paths that
were latently broken by Optional fields slipping through:
perplexity_adapter.py — pure typing. Cast the deepcopied messages to
`list[dict[str, Any]]` for the role-merging / system-conversion /
trailing-assistant-removal transformations and cast back to
ChatCompletionMessageParam at the return.
bedrock_adapter.py — pure typing. Cast the message to
`dict[str, Any]` at the top of `_from_standard_message` for the
tool-result / tool-use / image-content transformations. Cast the
constructed dict at the return site of `get_llm_invocation_params`.
gemini_adapter.py — typing + several None guards on Content.parts and
related Optional fields. Each guard turns a latent
`TypeError`/`AttributeError` (when the type-system-allowed None
showed up at runtime) into a defensive skip — the type annotations
say these can be None and we now handle that.
open_ai_realtime_adapter.py:
- Typing: cast the deepcopied messages, cast back where needed.
- LLMSpecificMessage handling: previously the function would crash on
the first `.get()` call if any LLMSpecificMessage was in the list.
Filter them out and document the limitation — this adapter's
pack-into-single-text-message strategy doesn't compose with opaque
per-provider payloads.
- Real bug fix: `events.ConversationItem` is a Pydantic BaseModel,
not a TypedDict. The bulk-packing path was constructing a raw dict
where a ConversationItem was expected. Replaced with proper
constructor calls (matches what the single-user-message path
already does).
- Real bug fix: `_from_universal_context_message` was declared
`-> events.ConversationItem` but on the unhandled-message
fallthrough it logged and returned None implicitly. Raise
ValueError so the violation is loud, not silent.
Removes 4 newly-clean files from the pyright ignore list:
adapters/services/{perplexity,bedrock,gemini,open_ai_realtime}_adapter.py.
Net: -95 pyright errors (full-config: 775 -> 680).
