The README said the engine is held to `engine/test/vectors/protocol-v1.json`,
a path from the pre-split subtree layout that does not exist here. The vectors
live in flamenet-e2e and are read from there rather than copied, because a
copied vector file drifts and a drifting vector file stops being a check.
PublishedVectorsTest already searches for it and fails loudly when it cannot
find it; the README now says so, and names FLAMENET_VECTORS.
CONTRIBUTING records what a JVM test cannot tell you: Conscrypt and the JVM's
JCA are different providers, so :engine:test passing proves nothing about a
handset, which is what interop/ is for. Also the exception escaping a WebRTC
callback that SIGABRTs rather than surfacing, the missing permission that
presented as a dead button, and `*/` inside a KDoc reporting an unclosed
comment hundreds of lines from its cause.
