# TESS-M4-003 Operator Plugin Sketch

## Memory/retrieval slice — TESS-MEM-001

Introduce a transport-neutral `OperatorMemoryPlugin` in `packages/memory`. The plugin receives a server-derived `{tenantId, ownerId, sessionId}` scope and delegates to a registered `MemoryAdapter`; adapter and namespace are injected configuration, never caller input. Its operations are `capture`, `search`, `recent`, `stats`, and `startupContext`. Results carry configured instance, provenance, and namespace metadata. Capture/redaction occurs before adapter persistence; startup context uses a bounded candidate window ordered so project/flat-file truth takes precedence within returned material.

Registration remains replaceable-adapter based: the existing `registerMemoryAdapter(kind, factory)` / `createMemoryAdapter(config)` seam supplies the injected adapter to `createOperatorMemoryPlugin(config)`. Identity and namespace are configuration data; no interaction-agent name is embedded in keys or defaults.

## Remaining plugin foundations — TESS-PLG-001

- `packages/agent`: capability descriptors for runtime bootstrap, durable inbox/state hooks, and read-only fleet diagnostics. Each capability advertises supported operations and fails closed when absent.
- `packages/mosaic`: a catalog/registration surface for GitOps, fleet diagnostics, runtime bootstrap, Discord, and MCP/skill discovery. Catalog entries describe authority, input schema, and safe/read-only status; they do not invoke provider transports directly.
- Gateway/channel adapters consume these contracts through server-derived actor/tenant context and durable session state, preserving the replaceable-adapter boundary.

## First implementation boundary

The first PR slice should add the operator-memory plugin contract, configuration-injected adapter seam, scope isolation, provenance-bearing retrieval, and tests for namespace isolation plus a differently named configured instance. Durable inbox/outbox remains owned by the existing `DurableSessionCoordinator`; this plugin only supplies bounded context/capture at lifecycle boundaries.
