* feat(llm): re-resolve llm_overlay after input interpolation rewrites an agent's role
llm_overlay (#7500) resolves an agent's model at construction, by its role text.
A CrewBase crew declares roles as templates in YAML — "Researcher for {repo}" —
that Crew._interpolate_inputs rewrites at kickoff, after construction. An overlay
keyed by the interpolated role, which is the text every trace records, never
matched: on a production flow a plan routed 3 of 5 agents and left the two
templated ones on their declared model.
Agent.interpolate_inputs now looks the overlay up again when the rewrite changed
the role: a key sets llm to the mapped model (create_llm, as construction does),
carrying the streaming flag Crew.kickoff(stream=True) set on the instance it
replaces; a miss, no active overlay, or an unchanged role leaves llm exactly as
it is — construction's resolution and instance stand, nothing reverts. The
executor binds agent.llm per task, after interpolation, so the task runs on the
new model (pinned through prepare_kickoff). Not followed by the swap, documented:
a task's string guardrail LLM, an auto-created Memory LLM, the crew_creation span.

* fix(llm): read llm_overlay once per agent — a re-validation must not replace an llm the agent already runs on
Found while battle-testing the previous commit with real calls: the event bus registers
an agent in its RuntimeState the first time it emits, and RuntimeState(root=[agent])
re-runs Agent.post_init_setup on the same object. Inside a block that maps the agent's
role, the construction-time overlay read (#7500) then replaced the llm the agent was
already running on and dropped the state set on it (stream=True). An agent built outside
the block picked the mapped model up on its second standalone kickoff inside one, against
#7500's own contract; Crew.replay inside a block did the same.
A private flag marks the construction-time read as done; a re-validation keeps the llm the
agent has — the one construction resolved, or the one interpolate_inputs set when the
role changed. Copies (kickoff_for_each) are new instances and read the overlay as before.
Zero-cost tests through RuntimeState; docstrings corrected (a crew Memory built at kickoff
does follow the swap; a stream must be iterated inside the block).

Apply the same contextlib.closing pattern accepted in #7493 to the nine
remaining library-side sqlite3.connect sites: SQLiteFlowPersistence
(init_db, save_state, load_state, save_pending_feedback,
load_pending_feedback, clear_pending_feedback) and SqliteProvider
(checkpoint, prune, from_checkpoint). The connection context manager
only commits or rolls back, so the connections survived in a reference
cycle and kept flow_states.db / checkpoint databases locked on Windows.
Also close the read-back connections in test_checkpoint.py, which made
its TemporaryDirectory cleanup fail on Windows for the same reason.
Add lifecycle and failure-path regression tests.

For response_model calls the messages are flattened into one prompt for
InternalInstructor with an f-string, so a multimodal content list reached the
model as its Python repr. AGENTS.md's "Message Content" section says never to
str() the content; use message_content_text() instead.
* feat(tracing): collect human feedback and pause events in the trace
The trace listener subscribed to method and conversation events but not to
the review-gate events or the pause events, so a `@human_feedback` gate
reached the trace only as method_execution_started/finished. A trace could
not say that a run stopped for review, what the reviewer was shown, or what
they answered.
Subscribe to HumanFeedbackRequestedEvent, HumanFeedbackReceivedEvent,
MethodExecutionPausedEvent and FlowPausedEvent through `_handle_action_event`,
as the conversation events are, with the event's own type as the trace type.
Each is a whole-event payload via the default serialization path; no change
to `_build_event_data` or `complex_events`.

* fix(tracing): register the gate and pause handlers through _on, keeping the execution-uuid gate
The four new handlers, and the conversation handler this branch had switched by
mistake, registered with event_bus.on and so ran while a kickoff owned an execution
uuid — the case where the OTEL session records these events and the legacy collector
must stay idle. Restored to self._on like every other handler; a test binds an
execution uuid and asserts none of the five are collected into a legacy batch.
Docstrings on the handlers (review bot coverage note).

* test(tracing): under a tracing kickoff the session records the gate and pause events and the legacy batch stays empty
Two real flows under an in-memory tracing session (the lifecycle tests' pattern): a
@human_feedback gate answered at the console records human_feedback_requested and
human_feedback_received as spans; an async provider that parks the flow records
method_execution_paused and flow_paused. In both the legacy collector, gated by _on,
collects none of the four. Review bot: the uuid-gated test alone would have passed
with the session registrations missing.

* fix(memory): close sqlite connections in kickoff task outputs storage
`with sqlite3.connect(...) as conn` only commits or rolls back; it never
closes the connection, which then survives in a reference cycle until a
cyclic GC pass. Every Crew kept an open handle on
latest_kickoff_task_outputs.db, so on Windows the file stayed locked and
any later delete, rename or temp-dir cleanup failed with PermissionError
(WinError 32). Wrap each connection in contextlib.closing, keeping the
existing commit/rollback semantics, and add regression tests.

`_execute_single_native_tool_call` reads the tools handler's cache and
skips the tool body on a hit, but emitted its ToolUsageFinishedEvent
without `from_cache`, so the bus — and every trace built from it — saw a
replayed native function call as a live one. The text-protocol path
(ToolUsage.on_tool_use_finished) already carried the flag. One kwarg.

A per-run caller sometimes needs specific agents on a different model
without editing the code that builds them. `crewai.llm_overlay` adds a
process-context `role -> model` overlay:
with llm_overlay({"Researcher": "openai/gpt-4o"}):
crew.kickoff()
The overlay is read in the only two places an agent resolves its model from
its role: `Agent.post_init_setup` and `LiteAgent.setup_llm`. When the role is
a key, `create_llm` receives the mapped model instead of the declared `llm`;
otherwise, and outside the block, nothing changes. `create_llm` itself stays
role-blind.
The overlay is a ContextVar, so it follows the calling context and is always
reset on exit. It does not cross plain threads; callers threading agents must
propagate the context with `contextvars.copy_context().run(...)`. The module
docstring says so and a test pins the behaviour.

`agent_execution_started` and `agent_execution_completed` are in
`complex_events`, so `_build_event_data` hand-builds their payloads. Those
payloads shipped only agent_role/goal/backstory and dropped two required bus
fields: `AgentExecutionStartedEvent.task_prompt` and
`AgentExecutionCompletedEvent.output`. A trace therefore said which agent ran
but not what it was asked or what it answered.
Add `task_prompt` to the started payload and `output` to the completed one,
whole and untruncated. No new event types, no TraceEvent change.

JsonProvider writes checkpoints with encoding="utf-8" and the runtime
serialises non-ASCII text verbatim, but the checkpoint CLI still opened
them with the platform default encoding. On Windows (cp1252) `crewai
checkpoint info` raised UnicodeDecodeError and `list` showed a 0-byte
entry for any checkpoint containing non-ASCII text. Open the files as
UTF-8 and add regression tests for the three readers.
`Memory.read_only` was enforced only on `remember()` and `remember_many()`.
Two other paths still mutated the backing store:
- `update()` re-embedded the supplied content and wrote the record back.
- `recall()` refreshed `last_accessed` through `touch_records()`, so simply
reading a read-only memory left a persistent trace.
Both now respect the flag, so a read-only Memory leaves stored records
unchanged. `update()` returns the existing record untouched rather than
raising, matching the silent no-op behaviour of `remember()`. Explicit
deletion through `forget()`/`reset()` is deliberately unaffected.

* fix(llms): send reasoning_effort to every openai reasoning model
The completions path gated the parameter behind
is_o1_model = "o1" in model.lower(), a literal substring test. gpt-5, o3 and
o4-mini contain no "o1", so an explicitly configured effort was dropped and the
model thought at the server default. The request still succeeded, so nothing
surfaced -- one measured extraction ran 6.2s with the setting applied against
149.7s with it dropped.
The gate could not be widened: is_o1_model also drives
supports_function_calling, supports_stop_words and the system->user message
rewrite, so marking gpt-5 as an o1 model would report that it cannot call
tools. The parameter is forwarded unconditionally instead, matching the
responses path, and a model that genuinely does not support it says so in a 400
that is retried once without the key.
Also adds "minimal" to LLM.reasoning_effort, which gpt-5 accepts and the
Literal omitted, so the cheapest setting was unreachable on the typed surface.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* refactor(llms): gate reasoning_effort on model shape, not every model
Forwarding to every model made a non-reasoning model pay a rejected request
and a retry on every call. `_supports_reasoning_effort` matches on shape
instead -- the o-series, and GPT generation 5 onwards -- so gpt-4o and gpt-4.1
never send the parameter at all.
Matched by shape rather than by a list of names so a new member of an existing
family works without a release here; gpt-6 and o5 already classify correctly.
The unsupported-parameter retry stays as a safety net for the case the shape
match is wrong for a future family, where it costs nothing when the match is
right.

* fix(llms): honour reasoning_effort on compatible servers and fine-tunes
Review follow-ups. A fine-tune (ft:<base>:...) is judged by its base model.
On an OpenAI-compatible server -- anything whose effective base URL is not
api.openai.com, whether set explicitly, via env, or by a provider subclass --
the model name is the server's namespace and says nothing about support, so an
explicit setting is sent as configured; a 400 naming the parameter, in whatever
words the server uses, is recovered by retrying without it, unless it reads as
a complaint about the value. A model that rejected the parameter is remembered
per (endpoint, model) for the process so the rejected call is paid once, and
the drop is logged as a warning since a configured setting is not being
applied. The Literal also gains "xhigh", the remaining value the SDK accepts.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* fix(llms): recover reasoning_effort only on evidence the parameter is unknown
Two review follow-ups. The endpoint check now uses the same base URL precedence
as the client itself, so a `client_params` override selects the server. And a
rejection is recovered only when the message says the field is not one the
server knows -- OpenAI's two shapes plus the common compatible-server wordings
("unknown field", "Extra inputs are not permitted") -- rather than any 400 that
lacks a value-sounding word. A pydantic enum complaint such as "Input should be
'low', 'medium' or 'high'" names the parameter but is about its value, and
surfaces instead of being dropped.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* fix(llms): remember a reasoning_effort rejection only after the retry succeeds
Two review points on the reasoning_effort fallback. The rejection was recorded
before the retry ran, so a retry that died for an unrelated reason (a dropped
connection, say) silently stopped sending the configured effort for the rest of
the process even though a call without it had never succeeded; the (endpoint,
model) is now remembered only once the retry returns. And _effective_base_url
accepted only a str override in client_params while the SDK, and
_get_client_params, accept httpx.URL too, so a compatible deployment configured
with a URL object was detected as OpenAI and its rejection keyed under the wrong
endpoint; both forms are normalised to the string the client calls.

* fix(agents): request the forced final answer as a user turn
When an agent reaches max_iter, handle_max_iterations_exceeded appended
the "give your best final answer" instruction as an assistant message and
relied on assistant prefill to make the model continue it. Current Claude
models (Opus 5, Sonnet 5, Fable 5.x, the 4.6+ family) reject a request
that ends on an assistant turn with a 400, after the whole iteration
budget has already been spent.
The instruction is now appended as a user turn, which every provider
accepts. The handler's formatted_answer parameter is dropped: every
caller had already appended that text as the last assistant message, so
prefixing it again only duplicated history.

* fix(agents): stop the lite agent loop after the forced final answer
LiteAgent._invoke_loop fell through after handle_max_iterations_exceeded
and issued a regular LLM call on the same history, discarding the forced
answer. Break out of the loop the way CrewAgentExecutor already does, and
assert a single LLM call in the test.

* fix(agents): keep null in the task output schema embedded in the prompt
build_task_prompt_with_schema embeds the task output schema into the prompt
via generate_model_description, whose strip_null_types defaults to True.
Combined with ensure_all_properties_required, an Optional[str] = None field
reaches the model as a required, non-nullable string, contradicting the
provider-side response schema generated from the same model.
That sanitizer targets OpenAI strict function-calling schemas. This call site
produces prompt prose, where those constraints do not apply.
Pass strip_null_types=False, matching the existing call for tool schemas in
utilities/agent_utils.py.
Fixes#6774
* test(agents): cover the output_json branch of the prompt schema
build_task_prompt_with_schema embeds a schema on both the output_json and
the output_pydantic branch, and this PR changes both. The regression test
only built a Task with output_pydantic, so the output_json branch shipped
unpinned.
Parameterize over both output attributes. Checked on this branch with the
fix reverted: both cases fail on the missing anyOf, and both pass with it.
Also compare the anyOf members as a set, so member order is not part of the
test contract.

* fix(openai): surface gateway errors reported inside an HTTP 200
OpenAI-compatible gateways commit `200 OK` as soon as the upstream provider
accepts a request, so a later provider failure arrives in the body as an
`error` object with no `choices`. That reached the SDK's parse helper and
surfaced as `TypeError: 'NoneType' object is not iterable`, naming neither the
provider, the status, nor the fact that a timeout happened.
The four non-streaming paths now inspect the raw body before parsing and raise
the exception the upstream code maps to, so a masked 504 is catchable exactly
like an honest one. Streaming already had this guard inside the SDK.

* test(openai): teach the tool-cache fake about with_raw_response
The provider now reads the raw body before parsing, so a client double that

reasoning-effort retry and Snowflake doubles.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* test(tracing): reset the TraceCollectionListener singleton between tests
TraceCollectionListener caches a TraceBatchManager on the class and
`_initialized` short-circuits `__init__`, so batch state survives for the whole
xdist worker. `test_nested_agent_executor_flow_does_not_finalize_parent_batch`
left `trace_batch_id="debug-trace-batch"` behind, which moved every later trace
POST from /tracing/ephemeral/batches to /tracing/batches/<id>/events. The
recorded cassette then stopped matching, the agent retried, and the second call
found the cassette consumed -- surfacing as ConnectionError in an unrelated
test hundreds of tests later.
Reproduced deterministically by running the leaking test followed by
tests/tracing/test_trace_enable_disable.py::test_trace_calls_when_enabled_via_env;
fails on a68b5e903 too, so this predates the gateway fix it was blocking.
An autouse fixture now clears the cached instance after each test. Two canaries
pin the invariant and fail without the fixture.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* test(tracing): drop the unwritable _listeners_setup canary
Both review bots flagged that the canary read `_listeners_setup` off the class,
where it is always False, so it could never fail. Correct, and the suggested fix
does not work either: `BaseEventListener.__init__` calls `setup_listeners`
(base_event_listener.py:16), which sets the flag on the instance
(trace_listener.py:229), so reading it back through `TraceCollectionListener()`
is always True. Neither read observes a leak, so the canary is deleted rather
than replaced, with the reasoning recorded so it is not re-added.
The same finding showed the fixture was resetting two class attributes that are
never assigned at class level. Only dropping `_instance` is load-bearing, so the
fixture is now one line.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* docs(tracing): correct why the _listeners_setup canary is unwritable
setup_listeners returns early when tracing is off and no override applies
(trace_listener.py:213-220), assigning the flag at :229 only when it actually
registers. Construction therefore does not always set it, as the previous note
claimed: with tracing disabled the flag never even reaches the instance dict.
The instance read reports ambient tracing state rather than isolation, which is
a better reason not to assert on it than the one recorded before.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* fix(tests): clear trace batch state in place instead of dropping the singleton
Dropping `TraceCollectionListener._instance` made the next construction re-run
`setup_listeners`, re-registering its handlers on the event bus. That broke
tests/telemetry/test_task_failure_instrumentation.py, which requires exactly one
handler per event: the re-registered `on_task_failed` made two. Verified against
a53ecc17f, where the same sequence passes -- the regression was mine.
The leak that needed fixing was batch state, not registration, so the fixture
now clears the manager's batch fields in place. Handler cleanup already belongs
to `cleanup_event_handlers`, and `first_time_handler` keeps its reference to the
same manager object.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* fix(tests): clear tracing context vars so the listener can re-register
Bugbot flagged that keeping the singleton leaves `_listeners_setup` set, so after
`cleanup_event_handlers` wipes the bus `setup_listeners` returns early
(trace_listener.py:208) and tracing silently registers nothing for the rest of
the worker. Confirmed: after a tracing-enabled run, re-running setup restores 0
of 119 handler entries.
Dropping the singleton fixes that but previously broke
test_task_failure_instrumentation. The real cause was a third leak: the
`_tracing_enabled` context var stayed set, so the replacement listener still
believed tracing was on and re-registered `on_task_failed` next to telemetry's.
Clearing the context vars is what makes replacing the listener safe, so the
fixture now does both, and a canary pins it (fails with `assert True is False`
without the drop).

* fix(schema): support list-form "type" arrays in JSON schema conversion
_json_schema_to_pydantic_type already handles anyOf/oneOf for nullable
unions -- the form Pydantic's own schema generation produces for
Optional[T] fields -- but had no handling for the other, equally valid
JSON Schema way of expressing the same thing: a list-form type array,
e.g. {"type": ["string", "null"]}. This is what .NET/System.Text.Json
-based schema generators produce instead, so any MCP tool schema from
a non-Python server using this form crashed create_model_from_schema
outright with "Unsupported JSON schema type: ['string', 'null']" --
taking down the entire MCPServerAdapter connection, not just the one
affected tool.
Confirmed against a real self-hosted MCP server (Equibles,
github.com/daniel3303/Equibles): several of its tools (e.g.
ListCompanyDocuments's startDate/endDate filters) use exactly this
pattern, and MCPServerAdapter couldn't connect to it at all as a
result -- reproduced identically on both Windows and macOS.
Fix mirrors the existing anyOf/oneOf handling: treat each entry in a
list-form type the same way an anyOf member is handled, building a
Union of the corresponding Python types. A single-element list
collapses to that one type via typing.Union's own behavior, and
"null" entries resolve to None (matching how the type == "null"
branch already behaves), producing the same Optional[T] shape as the
anyOf case would.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
* fix(schema): preserve union members when applying FORMAT_TYPE_MAP
CodeRabbit flagged this reviewing #7058: the format override in
_json_schema_to_pydantic_field replaced the whole resolved type with
FORMAT_TYPE_MAP[format_], even when that type was a Union built from a
list-form `type` (or anyOf/oneOf) rather than a plain `str`. For a
schema like {"type": ["string", "null"], "format": "date-time"}, this
collapsed Union[str, None] down to plain datetime, silently dropping
the null option -- masked for non-required fields by the
Optional-rewrap at the end of the same function, but not for a
required-but-nullable field (a valid, if unusual, JSON Schema shape).
The same override also drops any non-string members of a multi-type
array (e.g. ["string", "integer", "null"]) regardless of required
status, since nothing rewraps those.
Narrow the override to the `str` member specifically: replace `type_`
outright when it's already plain `str`, or substitute only the `str`
element inside a Union via get_origin/get_args, leaving null and
other type-array members untouched.
Added two tests covering the previously-broken cases: a required
nullable formatted field, and a multi-type array (string/integer/null)
with a format.

* fix(bedrock): preserve streaming tool call arguments at contentBlockStop
Streaming Converse handlers accumulate tool input as JSON string deltas in
accumulated_tool_input but never fold it back into current_tool_use["input"],
so function_args reads an empty {} at contentBlockStop. Parse the accumulated
input into the tool-use block (with a {} fallback) in both the sync and async

* fix: append trailing user turn in native Gemini provider
GeminiCompletion._format_messages_for_gemini maps assistant messages
to Gemini's 'model' role but never guards against the resulting
contents list ending on a model turn. CrewAI's own agent loop (max
iterations, guardrail retries) can produce exactly that history, and
Gemini's generateContent API rejects it with 400 'Requests ending
with a model turn are not supported'.
Mirrors the existing Mistral/Ollama guard in
LLM._format_messages_for_provider, which never applies to Gemini
since gemini/google model strings resolve to this native provider
instead of the LiteLLM fallback path.
Fixes#6972
* fix: append trailing user turn for Gemini on the LiteLLM fallback path
LLM._format_messages_for_provider already guards Mistral/Ollama
against a trailing assistant turn, but Gemini models routed through
the LiteLLM fallback (no google-genai installed, or a model name not
recognized as native) had no equivalent guard. litellm's own
Vertex/Gemini transformation doesn't handle this either, so the
request reaches Gemini's generateContent API unguarded and 400s.
Complements the native-provider fix in GeminiCompletion, covering
both dispatch paths.
* fix: don't append text turn after unresolved Gemini function call
Address CodeRabbit review on #6973: appending a plain 'Please
continue.' user turn after a trailing model turn that contains an
unresolved function_call violates Gemini's function-calling protocol
-- it requires a matching functionResponse, not free text. Raise a
targeted error instead so the caller notices rather than silently
sending a malformed follow-up.
Also strengthens the native-provider formatting tests to assert exact
role sequence and text content (not just the last role), per review,
and adds a regression test for the unresolved-function-call case.
* fix: guard None parts when checking Gemini history for unresolved function call
contents[-1].parts is typed list[Part] | None; iterating it directly
failed mypy (union-attr) on 3.10-3.13. Narrow to [] before the any()
check and document the ValueError in the docstring.

* fix(llms): normalize scheme and port in Ollama base URL
OLLAMA_HOST follows Ollama's own convention and may be a bare host
("0.0.0.0") or a host:port pair ("127.0.0.1:11434") rather than a full
URL. _normalize_ollama_base_url only appended "/v1", so those values
produced invalid base URLs such as "0.0.0.0/v1", and every request
failed with the misleading error "Failed to connect to OpenAI API:
Connection error." - confusing, since no OpenAI model was requested.
Fill in the missing parts the way Ollama's own client does: prepend
http:// when no scheme is present, append the default port 11434 when
none is present and the scheme is http (https implies 443), then append
the /v1 suffix the OpenAI-compatible endpoint requires.
Six of nine realistic OLLAMA_HOST forms were affected, including
127.0.0.1:11434, which is Ollama's documented default.

* fix(llms): strip only the parsed path when normalizing Ollama base URL
Stripping trailing slashes from the whole URL before parsing corrupted
inputs that carry a query or fragment. "http://ollama/?tenant=acme" kept
a "/" path and produced a doubled "//v1", and a query or fragment ending
in "/" silently lost that character.
Parse first, then rstrip only parts.path. Adds regression tests for a
root path alongside a query and for a query value ending in "/".
Reported by CodeRabbit on #7206.

* fix(telemetry): accept 1/yes/on on disable flags
CREWAI_DISABLE_TELEMETRY=1 was ignored because the gate only matched true, so telemetry stayed on with no warning.
* fix(telemetry): warn once on unrecognized disable values
Stop repeating the same invalid-flag warning on every telemetry check, and drop the undocumented CREWAI_DISABLE_TRACKING alias from docs.

* fix(flow): resolve @human_feedback emit LLM from the project model
Omitting llm= no longer hardcodes OpenAI. Collapse and learn resolve through create_llm so MODEL / MODEL_NAME / OPENAI_MODEL_NAME win, then DEFAULT_LLM_MODEL.
* fix(flow): fail closed when human-feedback collapse cannot classify
Stop routing to emit[0] when the collapse LLM cannot be called or its response does not match an outcome. Empty skip still uses default_outcome.
* refactor(flow): extract human-feedback collapse matching helpers
Move match/require outcome helpers out of _collapse_to_outcome so the classify path stays flat.
* refactor(flow): catch only LLM call failures in collapse
Keep HumanFeedbackCollapseError from matching outside the call try so it is raised once and does not trigger a second prompt.
* fix(flow): treat non-object JSON as raw collapse text
Avoid AttributeError when the collapse LLM returns JSON that is not an object.
* feat(flows): add now() to the CEL expression environment
CEL expressions in flow definitions had no way to produce the current
date: the environment was built bare, so date-dependent flows failed at
runtime. Register a now() function that returns the current UTC time as
a CEL timestamp. The value is frozen once per kickoff so every
expression in a run sees the same instant, even across midnight.
Standard CEL covers formatting from there: string(now()),
now().getFullYear(), now() - duration('24h').
* chore(flows): drop redundant comment on _cel_now
* refactor(flows): derive CEL env and functions from one registry
A function now lives in one _CelFunctionSpec entry: its annotation for
compile and its implementation factory for evaluate, so the two cannot
drift. Run-scoped values move into _CelRunContext; adding one is a
field, not a new parameter through every helper signature.
* chore(flows): drop _CelRunContext docstring
* fix(flows): freeze a fresh cel now() on human-feedback resume
resume_async never passes through kickoff_async, so a flow restored
with from_pending() had no frozen instant and now() fell back to live
wall-clock per expression. Freeze a fresh instant at resume instead of
persisting the kickoff one: a flow can pause on feedback for days, and
expressions after resume must see today.
* Decouple platform tools from the integrations API
Define normalized selector and tool data so platform tool creation does
not depend on the legacy API response shape. This contract makes the
legacy client easier to replace later.
- Move action discovery and response normalization into LegacyClient.
- Pass ToolInfo from discovery through tool creation and execution.
- Replace the builder flow with direct factory orchestration.
- Preserve app, action, and connection data in immutable models.
- Build sanitized tool names from the full tool identity.
- Preserve legacy request, SSL, and failure behavior with contract tests.

* fix(llms): let current claude models use native structured outputs
NATIVE_STRUCTURED_OUTPUT_MODELS only listed 4.5-era prefixes, so Opus 5,
Sonnet 5, Fable 5 and Opus 4.8 fell through to the forced-tool-call
fallback. That path also overwrites params["tools"], so a call combining
tools with a response_model silently lost the caller's tools.
_infer_provider_from_model documented a pattern-matching fallback it never
performed, so a Claude release newer than the constants list resolved to
"openai". Bedrock ('.' in model) and Azure (every OpenAI prefix) are left
out of that fallback because they would capture gpt-* models.

* fix(llms): route bedrock-namespaced anthropic ids to bedrock
"anthropic.claude-*" is Bedrock's namespace, not the Anthropic API, and it
satisfies the anthropic prefix pattern. Settle it before the pattern loop so
an unlisted Bedrock id picks BedrockCompletion. The region-prefixed form
("us.anthropic.claude-*") was resolving to openai, so this repairs that too.

* fix(deps): raise snowflake-connector-python floor for CVE-2026-15925
GHSA-5cc2-282f-jjq2 (CRITICAL): the connector does not verify TLS hostnames,
so a network attacker can impersonate the Snowflake endpoint. Fixed in 4.7.1.
crewai-tools[snowflake] declares "snowflake-connector-python>=3.12.4", which
the lock had resolved to 4.6.0. Following the existing convention, the security
floor goes in [tool.uv] override-dependencies rather than the source
declaration, matching how cryptography is handled.
Relocking also refreshes numpy/humanfriendly/nvidia environment markers, which
re-resolution under the relative exclude-newer window produces regardless of
this change.
