Six review findings on the select surface, all reachable from the wire: **Resume read the header, not the log.** The switch was recorded as `agent-preset/selected` and every projection resolved from it, but `agentFor` still composed from `inspected.meta.agentPreset` — the value written once at creation. A blank session that switched and then ran turns came back after a restart under the ORIGINAL preset, restoring that history under the tool set it was not produced with, which is the mismatch this feature exists to prevent. `inspected` already carries the events. **Cold summaries dropped the preset entirely.** `summarizeCold` hand-copied three header fields and omitted the fourth, so a restored session reported no preset and the picker showed the deployment default. It now uses the same projection the attached path does. **`select` had no gate.** Two concurrent selects both passed the blank check; the second `unmountPresetFor` then found no record, because the first had already removed it, and both mounts installed into one agent layer. Selects on one session now queue, and the blank check is re-read inside the queue. This is not turn admission — a `session.prompt` racing a switch is the agent loop's to reserve — but it closes the select-versus-select tear-down. **A same-id restore was skipped.** The roster is a live directory, so "the same inputs that worked a moment ago" does not hold: a changed file is exactly how a same-id reselect fails, and skipping the restore left the agent with no composition at all. **`writable` was dead state**, initialized true and never set, so the row could never disable. It now carries `settings.describe`'s bit — a browser that may not write settings sees the current default and no control, rather than one whose write answers `settings-not-exposed`. **`list` was documented as id-ordered.** It is root-precedence order with each root's own presets sorted, first root to supply an id winning.
Packages
English | 中文
Packages use the @deepseek-ai/dsh-* scope. Each is a Cordis Service subclass or function plugin; contributions use ctx.effect(), ctx.on(), or ctx.waterfall(). Authoring rules: package and root.
Hierarchy
Packages live at packages/<group>/<pkg>/; groups are containers, while names remain @deepseek-ai/dsh-<pkg>. Each group README is the canonical package/ctx-key map.

Dependencies
The dependency graph is generated: docs/module-graph.md (pnpm run gen-module-graph, freshness-gated in CI).
Extension plugins depend on interfaces, never the concrete loop. dsh-agent-loop is swappable; UI, hook, and tool plugins use dsh-agent. Composition bundles, including dsh-agent-spine-demo, may depend on spine plugins. Capabilities split into interface / implementation / consumer packages; see capability seams.
Package READMEs cover purpose, APIs, extension points, and Model Experience unless on the model-agnostic omission allowlist. They also carry ## Known Limitations and Deferred Work or use its allowlist.
