Pagination is keyset based on ``unified_file_id`` so a key that owns
every file on the proxy still reads one bounded page at a time.
``purpose`` is applied after parsing, because the managed file table
keeps it inside the ``file_object`` blob instead of a column, and rows
whose blob will not parse drop out there too, so a chunk of rows can
yield fewer matches than the page holds. Successive chunks are read
until the page is full or the caller's rows run out, which keeps
``data`` non-empty while matches remain and its last id usable as the
next cursor. A first chunk that fills the page costs one query; once a
scan has to continue past it, the chunk widens to
``FILE_LIST_CONTINUATION_CHUNK_SIZE``, so the walk costs one query per
that many rows instead of one per page. That bound is per query, not
per request: the work is still linear in the rows the caller owns, and
a filter matching nothing reads every one of them, with no index
covering either the owner filter or the sort.

## Loop Ceiling
One intercepted request can chain several follow-up model calls, since the model often searches again after
reading the first set of results. `max_agentic_loops` caps how many of those follow-ups run, and it defaults
to 3. LiteLLM also breaks the loop early when the model asks for the exact same tool call twice in a row.
Set the ceiling on the feature, which the interceptor applies to `/v1/messages` requests:
```yaml
litellm_settings:
websearch_interception_params:
enabled_providers: ["bedrock"]
max_agentic_loops: 5
```
Or per deployment, which wins over the feature-level setting:
```yaml
model_list:
- model_name: claude-sonnet-4-5
litellm_params:
model: bedrock/us.anthropic.claude-sonnet-4-5-20250929-v1:0
max_agentic_loops: 5
```
Clients cannot set it. `max_agentic_loops` is on the proxy's untrusted-field list, so a request body that
carries it is ignored and one request can never drive an unbounded number of upstream model calls.
Both places are validated at config load, and a value that is not an integer of at least 1 stops the proxy
from starting rather than surfacing later. The per-deployment one is checked while the model list is read,
not on `LiteLLM_Params`, because the proxy builds its router with `ignore_invalid_deployments=True` and a
validator down there would drop the deployment silently instead of refusing to start.
When the ceiling is reached on a non-streaming `/v1/messages` request, the turn ends there and the client gets
the last response back with the internal `litellm_web_search` tool call removed and `stop_reason: end_turn`.
The client never declared that tool, so leaving the block in would hand it a tool call it has no way to answer.
The answer can be less complete than it would have been with more loops, which is the tradeoff the ceiling
buys. Where the refused call was the only block left, the turn comes back with no text in it at all.
Non-streaming is not a limitation on the client here, because a client that asked for a stream gets the same
treatment. Interception converts an intercepted `stream=True` request to non-streaming before the loop runs and
rebuilds the SSE stream from the finalized turn afterwards, so the ceiling is always reached on a response the
client has not seen yet. `AgenticStreamingIterator` is the one caller that reaches the loop with its events
already on the wire, and it keeps raising, because a finalized turn would arrive there as a second message
rather than as a replacement.
Two other surfaces do not get that treatment yet. `/v1/responses` returns its own shape that the finalizer does
not rewrite, so it still hands back the internal call. And `/v1/chat/completions` runs its own copy of these
rails in `litellm_core_utils/chat_completion_agentic_loop.py`, which still raises rather than ending the turn.
Both are tracked separately
---
## Streaming Support
WebSearch interception works transparently with both streaming and non-streaming requests.

Shared validation for the agentic loop ceiling.
``max_agentic_loops`` can be set in two places, and the two disagreed about
what a bad value means. The feature-level
``litellm_settings.websearch_interception_params.max_agentic_loops`` was
checked at config load, while a per-deployment
``model_list[].litellm_params.max_agentic_loops`` was passed straight through
to ``int(... or 3)``. That let a per-deployment ``0`` read as the default 3,
turning the tightest ceiling into the loosest one, and let a per-deployment
``"three"`` boot the proxy and then fail every request to that model.
Both settings now go through :func:`validated_max_agentic_loops`, which names
the field it rejected so the error says which line of the config to fix.
Anything that spells a whole number is still accepted, because the old
``int(... or 3)`` accepted those and a ceiling is routinely parameterized as
``max_agentic_loops: os.environ/MAX_AGENTIC_LOOPS``, which resolves to a
string. Rejecting ``"5"`` would stop such a proxy from booting on upgrade.

Unit tests for what an intercepted request returns once a safety rail refuses
another agentic loop.
The web search interception loop injects an internal tool (litellm_web_search)
that the client never declared. When the loop cap or the repeated-fingerprint
guard trips, the turn has to end with a terminal response: leaking that internal
tool_use block leaves the client holding a tool call it cannot answer.
Also covers the max_agentic_loops knob on websearch_interception_params, from

"""
Unit tests for preserving prior-turn ``reasoning`` input items when the
Responses API is bridged to chat completions.
Without this handling, a ``ResponseReasoningItemParam`` falls through to the
generic message branch, polluting the prompt as visible assistant ``content``
or being silently dropped. Chat-completions providers such as DeepSeek V4 and
Kimi K2.6 require the chain-of-thought to be replayed as ``reasoning_content``
on an assistant message.
Providers whose reasoning is signed (Anthropic, Bedrock converse) get their
blocks back through ``encrypted_content``, which LiteLLM itself writes as a
JSON array of thinking blocks on the response side.
