* refactor(messages): take the provider client from the injected HTTP pool
The messages route kept its own process-wide reqwest client, so it ignored
ssl_verify, CA bundles, client certs, proxies and every other setting that
litellm-http resolves. The machine now takes the HttpClientPool and the
call's HttpClientConfig, as OCR does, and the bridge passes its shared pool.

* refactor(http): hand out an owned Client and move chat, audio and OIDC onto the pool
HttpClientPool now returns litellm_http::Client, a newtype only crates/http
can build, so every provider client carries the resolved TLS, proxy and
timeout settings. Chat completions and audio transcription drop their
process-wide reqwest clients and take the pool and call config like
messages; their 600s ceiling moves to the request. OidcResolver takes its
client instead of building one, and the bridge hands it the pooled one.

* refactor(secrets): build Google, Azure and CyberArk manager clients from the pool
The native secret managers built bare reqwest clients, so they ignored the
host's TLS and proxy settings. load_native_manager now takes the pool and
the host config and hands each manager a pooled client.
CyberArk's CYBERARK_SSL_VERIFY and CYBERARK_CLIENT_CERT/KEY become an
override on the host config instead of a hand-built client. To express a
certificate and key in separate files, HttpClientConfig::client_certificate
is now a ClientIdentity that is either one PEM or a split pair.

* chore(clippy): only crates/http may build a reqwest client
Fence reqwest::Client, ClientBuilder and the TLS builder methods with
disallowed-types and disallowed-methods so new code takes a
litellm_http::Client from the pool. crates/http is exempt as the one place
clients are built, and testkit as a dev-only installer. Tests move to
litellm_http::Client::plain_for_test or a pooled client.

* fix(secrets-cyberark): keep verifying certificates when the host disables it
Python hands CyberArk its own ssl_verify, which wins over the global
setting, so CYBERARK_SSL_VERIFY unset or true still verifies even when the
host sets ssl_verify false. The pooled client copied the host's Disabled
and would send the API key unverified; fall back to the built-in roots
instead.

The legacy callback crate carried two rewrites that have nothing to do with the
Logging contract: litellm_credential_name inheritance and the max_budget and
num_retries_per_request checks. Any later callback host would need them
unchanged, which is the smell the crate's AGENTS.md now names. They are now a
Preflight the driver in litellm-host-python runs on the keyword view begin
returned, before the host projects from it, supplied by python-bridge and passed
through run_legacy_call. The call order is unchanged (setup, deployment hook,
credentials, limits) and a rejection still fails the call as a host failure, so
the failure callbacks run as before. The preflight rewrites the adapter's own
copy in place, so no extra dict copy and no new lifecycle method

* feat(tokenizer): give the Rust wrappers the tiktoken and tokenizers surface
Callers of litellm.encoding and litellm.create_tokenizer must see the same
read-only API whichever backend the catalog selects.
- OpenAIEncoding mirrors tiktoken.Encoding: n_vocab, max_token_value,
token_byte_values, encode_single_token, encode_with_unstable,
encode_to_numpy, decode_with_offsets, is_special_token, repr; the Rust
tiktoken crate keeps a Vocabulary beside each CoreBPE and reports the
requested encoding name (gpt2 stays gpt2).
- HuggingFaceTokenizer mirrors the read-only tokenizers.Tokenizer surface
(token_to_id, id_to_token, get_vocab, get_vocab_size,
get_added_tokens_decoder, num_special_tokens_to_add, padding, truncation,
encode_special_tokens, from_buffer); HuggingFaceEncoding gains the
char/word/token lookups, pad, truncate, set_sequence_id and merge.
Mutators stay on the Python tokenizer.
- from_json/from_pretrained claim the fork gate only when the huggingface
feature is compiled in; the surrogate fallback matches on the Codec.
- Tokenizer caching is keyed on the same catalog Context the dispatch runs
on; rust_tokenizer reads the encoding name without loading an encoding;
LITELLM_RUST parsing is cached.
- Drop the unused tiktoken_encoding_for_model export and Error::Download.

* fix(tokenizer): close the exhaustive matches with assert_never
CodeQL reads a `match` over a Literal with no default arm as an implicit
`None` return. `assert_never` makes the exhaustiveness explicit for both the
HuggingFace tokenizer loader and the Rust token-counter factory.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* feat(tokenizer): derive the fast counter from the shared tokenizer
The count-only counter (`fast` feature) and the codec each parsed the same
artifact: TokenCounter took the Anthropic JSON and the tiktoken rank files
from Python while Tokenizer loaded them again. One parse now serves both.
- FastTokenizer builds from a model another loader holds: `from_shared`
takes the Arc<tokenizers::Tokenizer> the HF codec keeps, and
`from_*_pairs` take the ranks the tiktoken vocabulary already parsed.
- `FastCounter::fast_counter` in the core crate derives it from either codec;
encodings the fast scanner does not reproduce are refused.
- Native `Tokenizer.count(text, fast=False)` opts into that counter, built
once per tokenizer on first use; `TokenCounter.from_tokenizer(tokenizer,
fast=False)` replaces the JSON and rank-file constructors.
- The Python route counts over the native tokenizers the codec path shares
(`native_encoding`, `native_anthropic`) and no longer reads rank files;
the packaged Anthropic tokenizer has one loader, `tokenizer_dispatch.anthropic`.
- Public wrappers gain `count(text, fast=False)`.

* fix(rust): preserve Python secret manager bindings
* refactor(rust-bridge): let settings projectors own their contract specs
Each settings group now declares its SettingSpec rows next to the projector
that reads them, and the manifest test derives python_settings.json from those
tables instead of a hand-copied duplicate. Field carries (group, name) instead
of a dotted path, and coercion gains the dict-item reader plus the Redis
Boolean, certificate-requirement, non-empty string, and numeric adapters that
the cache configuration projection adopts next.

* refactor(rust-bridge): capture the secret manager binding in one settings read
The secret_manager accessor now carries the live client and settings objects,
so the bridge classifies the binding from a single snapshot instead of
re-reading litellm globals. The unreachable native arm and the service alias
go away, the binding-to-state mapping moves next to the snapshot, and the
Python callback precomputes its key_manager name.

* refactor(rust-bridge): execute typed settings field declarations
* refactor(rust-bridge): compare cache backends by identity behind one exact trait
cache-response gains an object-safe ExactResponseCache so every exact-match
backend sits behind one pointer; WriteBuffer flushes through it. The bridge's
NativeResponseCache shrinks from nine variants and fifteen per-backend
accessors to an exact service plus the three semantic backends, and facade
mismatch detection compares BackendIdentity values instead of matching on
each backend type. Request projections move next to NativeRequest.

* refactor(rust-bridge): drive both Python-embedded semantic caches through one execution
Redis-semantic and Valkey-semantic operations now share one SemanticExecution
body: await the Python embedder, seed the task-local vector, run the native
backend, repeat per batch entry. Valkey drops its with_embedder path in favor
of the same seeded embedder, and each backend keeps its own embedding-failure
policy. PythonEmbedder exposes one call shape. Redis-semantic thresholds are
compared at the backend's f32 width, which un-breaks the redis-stack parity
tests that a 0.8 facade threshold failed before this branch.

Settings sources beyond HTTP (media fetch, Azure Document Intelligence,
Vertex, timeouts) need the same env lookup and precedence merge, so move
them out of litellm-http into core_utils::settings. Lookup readers name the
Python idiom they mirror: get keeps a present empty value like
os.getenv(X, fallback), truthy drops it like an `or` chain, enabled only
switches on for "true". SSL_CERT_FILE now reads through truthy, matching
Python's `if ssl_cert_file and ...` check.
