fix(router): drop the encrypted reasoning a fallback hop's target cannot decrypt (#45393)
* fix(router): drop the encrypted reasoning a fallback hop's target cannot decrypt

An order-based or configured fallback hop replayed the failed provider's
encrypted reasoning items to the next deployment, which answered 400
(Bedrock Mantle: invalid encrypted reasoning; OpenAI:
invalid_encrypted_content), so every multi-turn Responses fallback for
Codex-style clients failed. The hop now drops the encrypted reasoning
its target cannot decrypt and keeps each item's readable summary. With
encrypted_content_affinity on, the pin narrows to the hop's target
order instead of emptying it, so the hop reaches the next order
instead of failing with no deployments available.

* fix(router): keep encrypted reasoning a same-boundary fallback hop can decrypt

Unmarked encrypted reasoning on a hop is attributed to the deployment that just
failed, read from the retry breadcrumb, so a hop to a deployment on the same
api_base and api_key keeps it and a cross-provider hop still drops it. The hop
tests script the upstream at the httpx boundary instead of doubling the handler,
and the router coverage script lists the two hop helpers with their tests

* fix(router): read the hop's failed deployment from its own metadata bucket and carry it into the Responses mid-stream snapshot

* test(router): use a real Router without the origin deployment in the hop strip test

* test(router): cover the hop strip when no failed deployment is known

* fix(proxy): drop the router's fallback hop state keys from the client body

* fix(proxy): keep a request's max_fallbacks cap, drop only the hop state keys

* test(integration): audit cells for the fallback hop encrypted reasoning strip

Forty-five checked-in cells under tests/integration/routing prove the hop strips the previous deployment's encrypted reasoning on /v1/responses, /v1/chat/completions and /v1/messages (httpx, OpenAI and Anthropic SDKs, sync and async, streaming and not), that the affinity pin yields to the hop, that a client-sent fallback_depth, _target_order and attempted_targets never move or strip a request, and that a concurrent burst, an order-1 outage and a killed worker keep every request stripped and logged once. Every call goes through a lane pinned to one worker that already lists the deployments it needs, because the peer worker learns a /model/new row through the config-sync resync up to sixteen seconds later

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.
