First of 11 PRs implementing the memory-system plugin refactor (RFC #2728). This PR is pure additive scaffolding — no behavior change, no integration yet. It defines the wire shape between workspace-server and a memory plugin so PR-2 (HTTP client) and PR-3 (built-in postgres plugin) can be built against a single source of truth. What ships: - docs/api-protocol/memory-plugin-v1.yaml: OpenAPI 3.0.3 spec covering /v1/health, namespace upsert/patch/delete, memory commit, search, forget. Auth-free (private network only); workspace-server is the only sanctioned client and the security perimeter. - workspace-server/internal/memory/contract: typed Go bindings with Validate() methods on every wire object so both client (PR-2) and server (PR-3) self-check at the boundary. - Round-trip JSON tests for every type (catch asymmetric tag bugs). - 5 golden vector files under testdata/ pinning the exact wire shape; update via UPDATE_GOLDENS=1. Coverage: 100% of statements in contract.go. The validation rules encode design decisions worth flagging in review: - SearchRequest with empty Namespaces is REJECTED at plugin level — workspace-server is required to intersect the readable set server-side; an empty list reaching the plugin is a bug. - NamespacePatch with no fields is REJECTED — empty patches are pointless round-trips. - MemoryWrite with whitespace-only Content is REJECTED — zero-info memories pollute search results. No code yet calls into this package; integration starts in PR-2. |
