JSON instances (`ToJSON` / `FromJSON`) and `Hashable`+  are derived separately via `deriving anyclass` on the generated types.+* `Proto.TH.loadProto` Template Haskell splice that runs the parser+  and the deriver together for an in-place `data` + instances bundle.+* Inline `[proto| ... |]` quasi-quoter for one-off types+  (`Proto.TH.QQ`).+* `Proto.Setup` Cabal `Setup.hs` integration hook for pre-build+  protobuf code generation.+* `protoc-gen-wireform` `protoc` plugin (`--wireform_out=DIR`).+* Allocation-disciplined wire-format primitives: unboxed-sum decoder+  result (`Proto.Wire.Decode`), two-pass sized encoder+  (`Proto.SizedBuilder`, `Proto.Encode.Archetype`), pre-computed+  field tags, packed repeated field encode/decode, branchless varint+  sizing, lazy submessage decoding.+* Proto3 canonical JSON mapping with `json_name` override, base64+  bytes, string-encoded 64-bit integers, and NaN/Infinity sentinels.+  Generated types get `ToJSON` / `FromJSON` instances automatically;+  the implementation lives in `Proto.Internal.JSON` and+  `Proto.Internal.JSON.WellKnown`.+* Well-known types (`Timestamp`, `Duration`, `Any`, `FieldMask`,+  `Struct`, `Value`, `ListValue`, `NullValue`, `Empty`, `Wrappers`,+  `SourceContext`) generated from the bundled `.proto` files by the+  `regen-wkt` executable (`cabal run regen-wkt`).  Supplementary logic+  (  `Proto.Google.Protobuf.*.Util`) ships `packAny`, RFC 3339+  formatting, `TypeRegistry`, `FieldMask` ops. Well-known types are+  regenerated from the bundled `.proto` files by `cabal run regen-wkt`.+* Proto2 typed extensions (`Proto.Extension.HasExtensions`),+  unknown-field round-trip preservation, dynamic / untyped messages+  (`Proto.Dynamic`), `.pbtxt` text format I/O+  (`Proto.TextFormat`), and a runtime `MessageRegistry`+  (`Proto.Registry`).+* Streaming and incremental decoders+  (`Proto.Decode.Stream`, `Proto.Decode.Streaming`).+* gRPC service-method codegen. `loadProto` and the other codegen entry+  points generate typed service/method descriptor values. Wire framing+  and transport live in the `wireform-grpc` package.+* Conformance test driver (`Proto.Conformance`) that exposes the+  protocol expected by the upstream+  [`conformance_test_runner`](https://github.com/protocolbuffers/protobuf/tree/main/conformance).+  Today's baseline against `protocolbuffers/protobuf@v28.2`:+  2675 successes, 0 unexpected failures across proto3 + proto2,+  binary + JSON suites.

No build system setup, no+generated files to commit. wireform's own parser handles the+`.proto`; `protoc` is not involved.++`loadProtoWith` accepts a `LoadOpts` for customising field+representations (see+[Custom field representations](#custom-field-representations)).++### `Proto.TH.QQ`: inline quasi-quoter++For one-off messages or quick prototyping:++```haskell+{-# LANGUAGE QuasiQuotes #-}+{-# LANGUAGE TemplateHaskell #-}+import Proto.TH.QQ (proto)++[proto|+  syntax = "proto3";+  message SearchRequest {+    string query = 1;+    int32 page_number = 2;+    int32 result_per_page = 3;+  }+|]+```++`SearchRequest` is now a regular Haskell type with+encode/decode/JSON instances.++### `Proto.TH.Derive`: annotation-driven, no `.proto` file++Define your Haskell types first, derive the wire format from+annotations:++```haskell+{-# LANGUAGE TemplateHaskell #-}+import Proto.TH.Derive (deriveProto, tag)++data Measurement = Measurement+  { sensorId    :: !Text+  , temperature :: !Double+  , timestamp   :: {-# UNPACK #-} !Int64+  } deriving stock (Show, Eq, Generic)++{-# ANN type Measurement ("Measurement" :: String) #-}+{-# ANN sensorId    (tag 1) #-}+{-# ANN temperature (tag 2) #-}+{-# ANN timestamp   (tag 3) #-}++deriveProto ''Measurement+```++Useful when the Haskell types are the source of truth and protobuf+is just the serialisation format. You get `MessageEncode` / `MessageDecode` instances like every other path.++### `Proto.Setup`: Cabal pre-build hook++For projects that prefer generated `.hs` files on disk (reviewable,+committable, visible to HLS without a TH rebuild):++```haskell+-- Setup.hs+import Distribution.Simple+import Proto.Setup++main :: IO ()+main = defaultMainWithHooks simpleUserHooks+  { preBuild = \args flags -> do+      protoGenPreBuildHook defaultProtoGenConfig+        { pgcProtoDir     = "proto"+        , pgcOutputDir    = "gen"+        , pgcModulePrefix = "Proto.Gen"+        }+      preBuild simpleUserHooks args flags+  }+```++```yaml+# in your .cabal file+build-type: Custom++custom-setup+  setup-depends: base, wireform-proto, Cabal, directory, filepath, text++library+  hs-source-dirs: src, gen+```++Incremental: only regenerates when a `.proto` file is newer than+its `.hs` output.++### `protoc-gen-wireform`: protoc plugin++If your build system already runs `protoc` (Bazel, Nix, Make,+polyglot monorepo):++```bash+protoc --plugin=protoc-gen-wireform=$(cabal list-bin protoc-gen-wireform) \+       --wireform_out=gen/ \+       proto/*.proto+```++Reads `CodeGeneratorRequest` from stdin, writes Haskell source via+the same codegen machinery.++### `Proto.CodeGen`: pure-text code generator++Lowest-level entry point. `generateModuleText` takes a parsed+`ProtoFile` AST and returns the Haskell module source as `Text`.+No TH, no IO, just a pure function:++```haskell+import Proto.Parser  (parseProtoFile)+import Proto.CodeGen (generateModuleText, defaultGenerateOpts)+import qualified Data.Text.IO as TIO++main :: IO ()+main = do+  src <- TIO.readFile "message.proto"+  case parseProtoFile "message.proto" src of+    Left err -> print err+    Right pf -> do+      let code = generateModuleText+                   defaultGenerateOpts { genModulePrefix = "MyApp.Proto" }+                   mempty "message.proto" pf+      TIO.writeFile "gen/MyApp/Proto/Message.hs" code+```++This backs `Proto.Setup`, `protoc-gen-wireform`, and `loadProto`.+Useful for custom CLI tools, non-Cabal build systems, or generation+as part of a larger pipeline.++### Which one should I use?++| Method | When to use it |+|:---|:---|+| `loadProto` | Most projects.

For example, a "group" defines+    --   both a type and a field in a single declaration.  Thus, the locations+    --   corresponding to the type and field and their components will overlap.+    -- - Code which tries to interpret locations should probably be designed to+    --   ignore those that it doesn't understand, as more types of locations could+    --   be recorded in the future.+  , sourceCodeInfoUnknownFields :: ![UnknownField]+  }+  deriving stock (Show, Eq, Generic)+  deriving anyclass NFData++data SourceCodeInfo'Location = SourceCodeInfo'Location+  { sourceCodeInfoLocationPath :: !(VU.Vector Int32)+    -- ^ Identifies which part of the FileDescriptorProto was defined at this+    -- location.+    -- +    -- Each element is a field number or an index.
