0.8.5 — small fixes mop-up

httpware 0.8.5 — small fixes mop-up

Patch release. Four small unrelated fixes. No API change, no user-visible behavior change on the happy path. Closes 4 of the remaining audit findings — two Low (chain.py + pydantic.py), two Nit (LoggingMiddleware docs + public-API test).

What changed

• typing.get_type_hints(compose_async) and typing.get_type_hints(compose) now resolve cleanly. The AsyncMiddleware / Middleware imports moved out of the if typing.TYPE_CHECKING: guard in httpware/middleware/chain.py; runtime introspection of the chain-composition signatures works. No behavior change for users not calling get_type_hints.

• PydanticDecoder no longer has a NameError window on test-reload. httpware/decoders/pydantic.py now imports pydantic.TypeAdapter unconditionally at module top. The optional-extras gate is enforced upstream by client.py:_default_pydantic_decoder(), so loading this module without pydantic was already not a real-world path. The previous conditional import left TypeAdapter undefined when the install flag was patched off, raising NameError instead of the documented ImportError if anyone reloaded the module under the flag patch.

• LoggingMiddleware example in docs/middleware.md uses logging, not print(). CLAUDE.md lists "No print()" as a non-negotiable invariant; copying the example into a user's project would have failed their own ruff check. The new snippet mirrors the RequestIdMiddleware style further down the same file.

• Public-API test catches bogus __all__ entries. test_expected_exports previously checked only expected - set(__all__); now it asserts set equality so a symbol added to __all__ without a peer update to the expected set is also caught.

Upgrade

uv add httpware==0.8.5
# or
pip install -U 'httpware==0.8.5'

No import changes. No API changes. The only behavior change is that from httpware.decoders.pydantic import PydanticDecoder now fails with a real ImportError at import time when pydantic isn't installed (instead of succeeding-then-failing-at-construct). The audit finding documented that the previous behavior was unreachable in practice — the upstream fail-fast at _default_pydantic_decoder() is the real safety net.
