• Keep interface contracts connected to modeled ReadModels so teams can understand declared APIs without inferring behavioral paths.
• Preserve exact contract selections through concurrent edits and native authoring so references cannot silently bind to replacement members.
• Keep unresolved dependencies inspectable while protecting restricted data and preventing unsafe deletion.

PR Summary

High Risk
Raises the wire contract revision and adds a large new entity with member/connection identity, branch-merge semantics, authorized reference resolution, and retained artifact bytes—areas where mistakes affect compatibility and data integrity.

Overview
This PR ships the Specification/API contract slice as a native Specification entity (wire contract revision 11, with client and server mutation floors raised to 11). Clients and servers must be upgraded together before authoring these resources.

The protobuf model adds retained contract artifacts (with digests), members (ContractMemberId), identified associations (connection_id on schema bindings, operation messages, exposures, usages, etc.), provider exposures/usages, and dependencies. API classification is derived from operations plus local provider exposures, not a separate kind.

Core and persistence introduce trogon-atlas-core::specification to assign and preserve member IDs, enforce immutable artifact bytes/digests, validate the local graph, and integrate with branch landing/resolution (member removal, restore, exposure ID rewrite). Connection traversal treats Specification association messages as identity-significant occurrences.

Server admission extends architecture validation and reference loading to Channel, DataStore, and Specification, including TypeLibrary compile checks for library_type schema bindings and SPECIFICATION_REFERENCE_UNRESOLVED diagnostics on validate-project. Reference/impact scan budgets now count Specification rows with Channel/DataStore.

Authoring surfaces gain manifest JSON schema, CLI/MCP export/apply round trips (preserving member/connection IDs and CRLF artifact bytes), Studio review tests, and docs/acceptance status moved from pending to implemented with links to executable fixtures.

Walkthrough

The change adds Specification as a native resource, with protobuf and manifest contracts, core identity and reference handling, server validation and admission, CLI/MCP round trips, and Studio rendering. Documentation describes the implemented scope and wire-compatibility requirements.

Merge Risk: 🔵 Low · up to 384cb

This PR adds Specification as a native resource across the API, CLI, MCP and Studio. When the protobuf compiler is slow or unavailable, project validation can report valid library-typed contracts as broken. The false errors clear once the compiler recovers. The PR is mergeable with that follow-up in mind.

Then Studio shows the links it knows.

Compile each selected library once per ValidateProject call.

The loop calls check_contract_type once for each library-type binding in the whole snapshot. Each call rebuilds the registry from context and compiles the selected library and its dependency closure again. When many Specifications select the same library, one ValidateProject call runs many identical compilations, and every compilation goes through the compile runner with its own timeout. Memoize the result by (library id, message) inside the call, or compile each library key once and check the message names against the cached result.
