Builds on merged PR-1..7 (PR-8 in queue). Pure docs; no code.
What ships:
* docs/memory-plugins/README.md — contract overview, capability
negotiation, deployment models, replacement workflow
* docs/memory-plugins/testing-your-plugin.md — using the contract
test harness to validate wire compatibility, what the harness
DOES NOT cover (capability accuracy, TTL eviction, concurrency)
* docs/memory-plugins/pinecone-example/README.md — worked example
of a Pinecone-backed plugin: capability mapping (only embedding,
no FTS), wire mapping (memory → vector + metadata), production-
hardening checklist
Documentation strategy:
* Lead with what workspace-server takes care of (security perimeter,
redaction, ACL, GLOBAL audit, prompt-injection wrap) so plugin
authors don't reimplement those layers
* Show three deployment models (same machine / separate container /
self-managed) so operators see their topology
* Capability table makes it explicit what each capability gates so
a plugin that supports only one (e.g. semantic search) is still
a useful plugin
* Pinecone example is honest: shows the skeleton, the wire mapping,
and explicitly calls out what's MISSING from the sketch (batch
commits, TTL janitor, circuit breaker, metrics)
