Bootstrap Protobuf and Buf contracts with generated Go and Rust packages

[zoeyrose]

Outcome

Establish fresh atrinik/protocol as the MIT source of truth for Atrinik Game Protocol 1, with a new Protobuf schema family, Buf policy, specifications, fixtures, and reproducible generated Go/Rust contracts.

This repository does not import or extend the classic numeric C/Python registry in atrinik/classic/protocol.

Repository shape

• Versioned packages such as atrinik.game.v1; package ownership follows bounded domain contracts rather than one monolithic message file.
• Buf module/configuration for lint, formatting, dependency pinning, breaking-change baseline, and deterministic descriptor output.
• Pinned generators for Go and Rust/prost with reproducible commands and generated-drift CI.
• Human-readable specifications for semantics Protobuf cannot express: limits, ordering, authorization, state machines, framing, error behavior, and compatibility.
• Golden descriptors/messages plus independently authored negative fixtures.

Quality and release gates

• Aggregate required check: Protocol validation.
• Schema lint, breaking check, generator drift, Go/Rust builds/tests, cross-language golden/negative tests, fuzz-target compilation, dependency/license audit, and docs link validation.
• Release schema source, descriptor set, generated packages/artifacts, fixtures, checksums, SBOM/provenance/notices, and compatibility manifest.
• Generated code license headers and provenance are explicit.

Acceptance criteria

• Clean Go and Rust consumer examples build from a released/pinned protocol artifact without sibling repositories.
• No C/Python binding, classic ID registry, MAP2/ADS-2 compatibility path, or GPL dependency exists.
• Generation is deterministic and pinned; CI catches tool/schema/output drift.
• Breaking policy has a baseline and documented exception/major-version process before M2 consumers stabilize.
• Protobuf bytes are never treated as a canonical content/state hash without a separately specified canonicalization.

Licensing

Schemas/specs/generators are MIT. Verified original past material may enter only through the merged approved MIT provenance-grantor registry and complete-history evidence policy in atrinik/atrinik#275.
