Epic: Wire protocol v2 #192

Outcome

Deliver canonical request correlation, responsive bounded connections, cancellation, ordered revision publication and explicit complete-or-reset delivery. G2 covers W04/W05; SDK adoption is the R3 checkpoint and shares this exact contract.

Child issues

• Wire v2: canonical request IDs and typed notices #171
• Wire v2: responsive connection reader and bounded single writer #172
• Wire v2: end-to-end deadlines and cancellation by request ID #173
• Wire v2: ordered revisions, stream reset and complete delta delivery #174

Completion

Keep this tracking issue open until its selected release scope passes. Child issues in a later milestone remain visibly deferred; a partial slice does not complete a broader issue. Every change runs the performance pipeline in #163 before a pull request.
