* cdylib events: Qt-free types, and drop the unused bytes encoder Three follow-ups to the bstr event fix, all in the cdylib events sidecar -- a Qt-FREE translation unit: - An `any`/map event parameter was emitted as a bare QVariant/QVariantMap, which does not compile there. Spell those as their nlohmann aliases (LogosMap / LogosList) and pull in <logos_json.h> when they appear. - std::vector<std::vector<uint8_t>> fell through the impl-header parser's unknown-type fallback to `any`, so the cdylib gate admitted it and the generator then emitted QVariant. Parse it as `[bstr]` so the gate rejects it with a message naming the offending parameter. - The bytes encoder was emitted into every module's sidecar, leaving an unused static function (-Wunused-function) wherever no event carries binary data. Emit it only when a bstr event parameter exists.

A consumer subscribing to a binary event was handed the raw tagged JSON object {"_bytes": "<base64url>"} instead of the bytes, with no generated decode. Teach the tables about QByteArray (-> std::vector<uint8_t>) and marshal it through the canonical tagged form in both directions: logos::bytesToJson on the way out, logos::jsonToBytes on the way in. Those live in logos_json.h -- Qt-free and protocol-free, so the generated wrappers and module code can share them. The Qt apiStyle already did this via QByteArray::toBase64/fromBase64. Without this, a subscriber written the obvious way -- onBinaryReady([](const std::string&, const std::vector<uint8_t>& payload) {...}) -- compiles (nlohmann::json has an implicit conversion operator) and then throws at runtime on every event, so the callback body silently never runs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * tests: cover binary event payloads by value, not just by source text The regression test for #99 asserts on generated source text, so it stays green against an encoder that emits the wrong bytes. Add the value-level half: - tests/sdk/test_logos_json_bytes.cpp exercises the canonical tagged-bytes codec against the RFC 4648 vectors, the URL-safe alphabet, every len%3 tail group, embedded NULs and high bytes, a 109,447-byte payload (the size from #99), and the lenient/padded decode paths. - tests/experimental/test_lidl_gen_cdylib.cpp additionally pins the Qt-free spelling of JSON event payloads, the rejection of [bstr], and the omission of the bytes encoder from modules whose events carry no binary data. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * doctests: prove a binary event payload survives the round trip Neither doc-test covered bytes-in-an-event -- the gap #99 fell through. The generator round-trip carried `bstr` only as a method argument and return, and the composition doc-test, which is the one that actually runs two modules under logoscore and subscribes to an event, carried only a string. So a generator that dropped every bstr event argument kept both of them green. - cpp-sdk-module-composition: greeter_module gains a `blobReady(label, payload)` event and an `emitBlob(size)` method; orchestrator_module subscribes and reports the length AND a checksum of what it received. Length alone would not catch a corrupted payload -- a wrong alphabet round-trips to the same size. - cpp-sdk-generator-roundtrip: sensor_module gains a `capture(id, frame: bstr)` event, and a new step shows the generated event body encoding it through lidlBytesToJson rather than pushing it raw.

Include <cstddef> directly so the header is self-contained. (Copilot review, PR #102.)
