+outcome: Shipped via #77 — resolution + pre-flight MissingDecoderError + DecodeError wrapping moved into _DecoderResolver/_BoundDecoder (decoders/_resolver.py); the 4 send/send_with_response sites collapse to resolve→dispatch→bound.decode, both _dispatch_decoder methods removed, decoder+model sealed together. Behaviour byte-identical (723 tests, 100% coverage). New seam suite tests/test_decoder_resolver.py; promoted into architecture/decoders.md. Internal refactor — no release.
