fix(chatgpt): forward text and max_output_tokens to the Codex backend (#38086)
* fix(chatgpt): keep text and accept string input for the Codex backend

Two request-side defects stop chatgpt/* serving structured output or a string
input.

The allowlist at the end of transform_responses_api_request omits "text". The
chat-to-responses bridge translates response_format into text.format, so the
allowlist discards strict schemas silently and the backend answers with prose
instead of JSON. The backend does honour text.format when it receives it.

Separately the backend rejects a bare string input with
{"detail": "Input must be a list"}, while the Responses API itself accepts
either shape, so the string needs wrapping before it is sent.

Both are request-shaping only, so neither depends on the streaming work in
#31332 or #34095, though those two block the same call and have to be in place
to observe this one end to end.

The "text" case was reported in #24356 and closed by the stale bot without a
fix.

* fix(chatgpt): annotate the input coercion for the type-discipline gate

The LIT002 budget counts mutable-collection construction, and wrapping the
string input builds a list and a dict, which put the total two over its
ceiling. Both constructions are the wire payload this backend requires, so the
list cannot be replaced with an immutable equivalent; annotate the line with a
reason instead, matching the convention used elsewhere in the tree.

LIT005 freezes reasonless suppressions at zero, so the reason is required
rather than decorative.

* refactor(chatgpt): bind the coerced input instead of rebinding the parameter

Greptile flagged the parameter rebinding and the explanatory comments against
the repo conventions in CLAUDE.md, which bans rebinding a function parameter
(LIT011) and keeps comments to suppressions, TODOs and genuinely complex logic

Bind a Final local for the coerced input rather than reassigning `input`, and
drop both prose comments; the rationale lives in the commit and the PR body
rather than duplicated at the call site. The mutable-ok suppression stays,
since it is the allowed kind and the list is still constructed

Behaviour is unchanged: 24 tests pass, and the same 4 fail with only the
provider file reverted to base

* fix(chatgpt): forward max_output_tokens to the Codex backend and return incomplete non-stream responses

The Codex backend accepts and enforces max_output_tokens, so the allowlist now keeps it
instead of dropping it. A structured-output request could otherwise stream until the
backend gave up, ignoring the caller's max_tokens.

A capped request ends with response.incomplete, so the non-stream SSE aggregator now
treats that event as terminal and returns the partial response instead of an error.

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
