Every `@` candidate query labeled each listed Session through three service lookups, and each lookup and method read through a Cordis service proxy allocates wrappers, so the labeling step grew with the Session count. The resolver now resolves sessions, projections, and the projection cache once per call, indexes attached Sessions in one map, and binds cachedSnapshot once for cold Sessions.

context/ — Request-context plugins

Summary
The context group provides plugins that add model-visible context to each request without defining any tool: workspace instruction files become guidance, @file mentions offer path completion, other sessions can be referenced as bounded snapshots, and the model can see the current time and the agent's tmux location. Only agent-instructions (dsh-base) ships mounted by default; the rest are opt-in. Context is durable: injected instructions and references enter session history as user-role messages, so they persist, replay, and compact like other conversation content. This page maps the group; each package README owns the per-package contract.
