Adds 'transition Name { ... }' as a top-level member of a speck
block. The AST node is TransitionNode with fields[] plus optional
payloadOneof and typeDiscriminator references. Two field names
have special meaning:
payload: <OneofName> → the generator will emit the referenced
oneof's variants inline as
'oneof payload { ... }' inside the
message body (i.e. payload becomes a
proto oneof, not a regular field)
type: <EnumName> → the discriminator enum for the variants
All other fields are emitted as ordinary proto message fields.
This is the shape federated-meetup needs for its Transition message:
message Transition {
TransitionType type = 1;
StateRoot prior_state = 2;
oneof payload {
CreateGroupPayload create_group = 10;
...
}
Multisig steward_signatures = 31;
bytes hlc = 32;
fixed32 branch_id = 33;
google.protobuf.Timestamp signed_at = 30;
}
The next cycle (64) will wire the .proto generator to emit this shape
from a TransitionNode. Cycle 58 is parser-only — 3 new tests cover
regular fields, payload+type references, and trailing punctuation
tolerance. All 46 tests (39 baseline + 4 oneof + 3 transition) pass.
tsc build clean.
