- Claude Opus 4.7 rejects `thinking.type: "enabled"` with a 400 error
and requires `thinking.type: "adaptive"`; adaptive is also the
recommended mode for Opus 4.6 / Sonnet 4.6 where `"enabled"` is
deprecated.
- The genai `ThinkingConfig.thinking_budget = -1` (AUTOMATIC) sentinel
is the natural mapping for adaptive: the model picks the depth
itself. Callers opt in with `-1`; positive values keep the existing
`"enabled"` path so older models are unchanged.
- Bump `anthropic>=0.78` in `pyproject.toml`; 0.78 introduced
`ThinkingConfigAdaptiveParam`. The previous floor (`>=0.43`) let
Kokoro install `anthropic==0.75.0`, which crashes the new tests
with `AttributeError: module 'anthropic.types' has no attribute
'ThinkingConfigAdaptiveParam'`.

Adds @functools.lru_cache to find_context_parameter so the inspect.signature
+ typing.get_type_hints lookup runs once per function, not on every MCP
confirmation callback or declaration build. No public surface change.

AgentTool.run_async only extracted text parts from the inner agent's
response, silently dropping code_execution_result.output and
executable_code.code. Outer agents using an inner agent with a code
executor saw nothing.

Previously, an empty `candidates` list without `prompt_feedback` resulted in an `UNKNOWN_ERROR`. This change updates the logic to handle such cases as a successful completion with no generated content, which is valid for certain model interactions like tool-driven turns.

`part_to_message_block` iterated `content` char-by-char when a tool
returned it as a plain string (e.g. `LoadSkillResourceTool`'s
`{"content": <file text>}`), producing `"H\ne\nl\nl\no"` instead of
`"Hello"`. Guard the list branch with `isinstance(..., list)` and add
a sibling branch that passes a scalar string through directly, matching
Anthropic's `content: str | list[ContentBlockParam]` shape.

This change introduces logic to identify events containing requests for tool confirmation or auth credentials. The compaction process will now stop before any such "Human-in-the-Loop" (HITL) events, ensuring that the full context of the interaction is preserved and not summarized away. This applies to both sliding window and token threshold compaction strategies.

This change enables the Google Cloud Telemetry exporter to use mTLS endpoints. It checks for the availability of client certificates and respects the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variables to determine whether to use the mTLS-specific endpoint and configure the session accordingly.

This change removes support for the deprecated `--session_db_url`, `--artifact_storage_uri`, and `--verbosity` flags from the ADK CLI. It also simplifies the service URI handling in `cli_deploy.py` by always using the new `--session_service_uri`, `--artifact_service_uri`, and `--memory_service_uri` flags, regardless of the ADK version.
The deprecated flags has been more than 1 year

This CL introduces logic to handle scenarios where a non-ADK agent transitions to the `TaskState.input_required` or `TaskState.auth_required` states. It intercepts these events and converts them into a synthetic ADK `FunctionCall` event.

When resuming a session with Anthropic (Claude) models, tool_use IDs were
getting stripped during content replay, causing BadRequestError from the
Anthropic API. Two fixes: (1) preserve function call IDs in the contents
flow for AnthropicLlm models, (2) sanitize invalid/empty tool_use IDs
to match Anthropic's required pattern (^[a-zA-Z0-9_-]+$) instead of
passing empty strings.

**Please ensure you have read the [contribution guide](https://github.com/google/adk-python/blob/main/CONTRIBUTING.md) before creating a pull request.**
### Link to Issue or Description of Change
**1. Link to an existing issue (if applicable):**
- Related: https://github.com/google/adk-python/issues/4971
**2. Or, if no issue exists, describe the change:**
_If applicable, please follow the issue templates to provide as much detail as
possible._
**Problem:**
A2A support lacked pluggable or persistent task store backends, forcing a strict default to `InMemoryTaskStore`.
**Solution:**
Extended `ServiceRegistry` and `ServiceFactory` to support URI-driven configuration for A2A task stores. Added built-in support for `memory://`, `postgresql://`, `mysql://`, and `sqlite://` schemes. Plumbed the options down into `to_a2a()` and `get_fast_api_app()`, ensuring connection strings are securely redacted from application logs.
### Testing Plan
**Unit Tests:**
- [x] I have added or updated unit tests for my change.
- [x] All unit tests pass locally.
Summary: Ran `pytest` against `test_agent_to_a2a.py`, `test_fast_api.py`, `test_service_registry.py`, and `test_service_factory.py`. All 131 unit tests passed successfully.
**Manual End-to-End (E2E) Tests:**
Compiled the package distribution wheel via `uv build` and successfully validated its installation inside a clean isolated sandbox environment via `uv pip install dist/google_adk-1.32.0-py3-none-any.whl[a2a]`. Verified that the application instantiates default in-memory stores and custom persistent URI stores

The analyzer crashed on `sum([None, ...])` whenever any event had
fingerprint-only cache metadata (cache_name=None, invocations_used=None),
which happens on every session's first turn. Also fixes `cache_refreshes`
over-counting None as a unique cache instance.

Generates a random code verifier and code challenge during the initial auth request. During token exchange, the client sends the original code verifier so the server can verify it matches the previously sent challenge. This prevents attacks by ensuring that only the client that initiated the request can obtain the final access token.
