* feat(proxy): give Codex accurate model entries for every model in /v1/models
* fix(router): read a deployment's upstream model without a not-required key access
* fix(proxy): keep Codex tiers for unpriced deployments and match stock entries by declared provider
A deployment with no token price no longer votes a Codex service tier off,
an undescribed model keeps Codex's default reasoning summary parameter,
a Bedrock deployment naming its provider in custom_llm_provider gets Codex's
stock entry, and Bedrock provider namespaces follow the AWS model id format.
* fix(proxy): import cost tracking and provider helpers lazily in the Codex catalog
lite codex imports the catalog before the SDK is initialized, so importing
cost tracking, the Bedrock helpers or provider resolution at module level hit
a circular import and broke every lite command.
* fix(proxy): drop Codex's fast speed tier wherever its priority tier is dropped
Codex shows /fast for a leftover fast speed tier even when service_tiers
no longer offers priority, so an alias, an empty configured tier list or
a configured list without priority showed a /fast toggle that sends nothing.
One helper now sets service tiers, speed tiers and the default together.
* fix(proxy): give an older Codex a translated entry for models past its version
Codex's own entries name the oldest release that can read them in minimal_client_version. A release older than that can fail to decode the entry, such as a reasoning effort it has no name for, which fails the whole catalog, so it now gets the translated entry, whose levels are trimmed to that release
* build: allow filelock 4.x
filelock 3.x is the only line the current cap permits, and three CVEs
(CVE-2026-112940, CVE-2026-112913, CVE-2026-112907) are fixed only in
4.2.1+. The cap means every downstream that depends on litellm is held
on a vulnerable filelock with no way out, since pip has no override.
litellm uses FileLock(path, timeout=..., mode=...) and Timeout, in
litellm/proxy/client/cli/commands/configure_profiles.py and
claude_settings.py. Both keyword arguments still exist in 4.2.4 and
Timeout is still exported, so the two call sites are unaffected. The
CVEs are in the SQLite-backed ReadWriteLock / AsyncReadWriteLock, which
litellm does not use.
<5 rather than a floor bump because litellm supports Python 3.10 and
filelock 4.x requires >=3.11: widening the cap lets 3.11+ resolve 4.x
while 3.10 keeps a 3.x filelock automatically, through filelock's own
requires_python.
* build: sync core filelock bound and dependency lock

Update certifi, Rust trust roots, and the Docker CA bundle to remove emSign ECC Root CA - G3
Require the fixed certifi release in litellm-core and retain libssl3 in Docker runtimes for Prisma compatibility

anyio below 4.14.0 can leave a cancelled waiter queued on an asyncio Lock or
Semaphore, so the next task to acquire waits forever on a lock nobody holds
(agronholm/anyio#1145, fixed in 4.14.0). httpcore takes these locks for every
httpx request, including the prisma query-engine client
litellm imports anyio directly but never declared it, so pip and uv kept an
already installed anyio 4.13.0 when installing litellm and accepted an
explicit anyio==4.13.0 next to it. uv.lock already resolves 4.14.2, so Docker
and CI installs do not change. Both the litellm and litellm-core manifests get
the floor, and the lock only records the new direct dependency

* fix: support OpenAI SDK 3.x while retaining 2.x compatibility
* fix: preserve HTTPX compatibility across OpenAI SDK versions
* refactor: trim OpenAI SDK compatibility patch
* refactor: simplify SDK client defaults
* test: cover SDK compatibility across provider routes
* fix: use shared names for SDK transport helpers
* fix: address SDK compatibility review feedback
* test(openai): send requests through the SDK API factory clients
* fix(exceptions): keep the provider response on PaymentRequiredError under httpx 2
* ci(base-sdk): count httpx2 as base-only when a base dependency brings it in
OpenAI SDK 3 depends on httpx2, so the litellm-core install at highest resolution pulls it in through openai. The base-only check now resolves the declared base dependency closure of litellm and litellm-core and accepts extras-only modules owned by a distribution inside that closure
* test: cover OpenAI SDK 3 client paths end to end and read SDK HTTP headers case-insensitively
* test: read C02 spend rows once, wait out the worker healthcheck on respawn, and resolve module owners on Python 3.10
