imccyu 92f9e79fac perf(session-projection): serve session-list rows from a summary key set
A Session-list row no longer carries every registered client view: the three
units whose values a list row never renders (`turnOutline`, `sessionStats`,
and `todos`) are excluded, which removes the whole-log turn outline and the
figure and todo payloads from every row. An opened Session is unchanged —
`session/follow`, the `session/control` baseline, and `session.projections`
still serve every projected key.

The exclusion is one type-level mark plus one registration interlock:
`SessionProjectionSummaryExcluded<T>` marks a map entry, and
`ProjectionDefinition.wire` requires `summary: false` exactly on a marked key
and rejects it everywhere else, so the mark and the declaration cannot drift.
A nullable entry keeps `null` outside the wrapper, so `todos` stays
`TodoItem[] | null`. `summaryKeys()` returns the derived set, stable until a
registration or its disposal changes the key table, and the existing
key-taking read faces (`cachedSnapshot`, `viewCheckpoint`) accept that set
directly, so summaries need no separate read face and no per-read key copy.
`packages/api/session-controller/src/list.ts` passes the set to the live and
cold cached faces; `cachedPredecessorTitle` is untouched.

Client types only: `SessionSummary.projectionValues` narrows to
`SessionProjectionSummaryValues`, `SessionProjectionSnapshot.values` keeps
every view value with the mark stripped, and no wire field or client name
changed. The cache, subsystem page, and package README document the summary
rule and the two read faces.

Runtime API inspection, process-local runners, and historical Cordis cards. package-group

packages/extensions

English | 中文

Summary

The extensions group provides read-only runtime API discovery for agents, process-local runners for programmatic and browser consumers, and historical generated-plugin cards. Creator mode installs persistent plugins through Plugin Manager. Choose a child package for inspection, Host execution, Client execution, or browser controls.

Table of Contents


Packages

Package Role ctx key
tool-cordis Two read-only tools for runtime API discovery registers on ctx.tools
cordis-host-runner Host half: definition registry, sandboxed host-half lifecycle, and the inspect registry that answers browser queries provides ctx.dynamicCordisRunner and ctx.cordisInspect
cordis-client-runner Browser half: evaluates a browser-half source into a live plugin and answers run requests client face; provides browser ctx.dynamicCordisRunner
ui-cordis Browser panel and historical lifecycle tool cards client face; registers slots


Dev Note

Working context for maintainers — click to expand

The two browser-half packages live in this group rather than under packages/client/ because they are halves of this subsystem's dual-half packages; the client face compiles them through the client program, while the host program references only the host runner.
