A test file under packages/client now says which face it covers:
`*.client.spec.{ts,tsx}` and its `*.client.{ts,tsx}` helpers belong to the
Client aggregate, `*.host.spec.ts` to the host aggregate. The carrier's four
node-half specs take the Host suffix.
The two suffixes are mutually exclusive, so each aggregate excludes the
other's and both keep one broad test glob: `exclude` wins over `include`, and
`packages/client/**` no longer has to be excluded wholesale from the host
program with per-file `files` entries carved back out of it. A Host-face spec
that reaches only Host source therefore needs no cross-face project
reference, which the split-project rule rejects.
vitest still discovers every file through `**/*.spec.{ts,tsx}`.

Client command API (ctx.command): the session-keyed command-directory cache, the / command source with matchSpace/matchEnter decision hooks, three-kind dispatch (execute / popupSelect / leadingInput), and popupSelect registration for business packages. The web command Agent Note records the decision.
src/client/contract.ts is the fixed business contract: CommandServiceContract.register(name, spec) and decorate(name, spec) are everything a business package consumes; CommandUiSpec{options, onSelect} keeps popup data self-contained — the shell component belongs to this package and business packages never see it. A contribution is a client-owned command (a host-name collision fails loud); a decoration adds a bare-invocation popup to an EXISTING host command. The host keeps its catalog row, argument claim (space / argued Enter), and lifecycle logging, and a decorated name with no host row in the session's directory never fires. Command kinds derive per dispatch, never per registration: a host descriptor with input is leadingInput, a registered CommandUiSpec is popupSelect, and everything else is execute.
CommandDirectory (src/client/directory.ts) is the one wire-derived cache, keyed by session. Ordinary sessions fetch through command.list({sessionId}), and the source's scope-birth warm hook prewarms the session's entry. Catalog-addressed continuable children resolve an empty command directory locally: command.list is Agent-bound, so prewarming it would activate a child merely to view persisted history. Entries are soft-invalidated by the forwarded commands/change owner event (old snapshots serve while the repull flies) and by forwarded agent-preset/selected for that one session (recomposing an agent registers nothing, so the registry-wide signal never fires for it), hard-invalidated by connection/reset, and epoch-guarded so a superseded pull can never overwrite a newer one. matchSpace answers synchronously from this cache only; matchEnter strong-waits it on the SubmitAttempt signal and rejects on warmup failure — a / line is never silently downgraded to a plain prompt.
Menu queries fuzzy-match ordered, case-insensitive subsequences of command names. Prefixes rank first; separator boundaries, adjacent characters, and shorter gaps rank the remaining matches, with directory and contribution order breaking ties. This affects discovery only: space and Enter still require an exact command name. Rationale: Web slash-command fuzzy discovery.
PopupSelectController (src/client/popup.ts) is the headless shell state: PopupSelectView self-registers into conversation.input.overlay (the SlotMap key is ui-conversation's; this package pulls the declaration in with a type-only import — no runtime edge). The shell is a transient layer holding focus while open; token-segment consumption after onSelect runs both branches through consumeTokenSegment (menu-path span CAS, enter-path bare-token equality) against the draft face the wiring layer binds via bindDraft.
The /client entrypoint exports the plugin body (apply/inject), CommandService, the directory and popup classes with their state types, and the fixed contract types; the shell component itself is internal to the overlay registration.
Model Experience
Indirectly, through the host command.execute RPC this package's dispatch and claim.submit paths trigger: a matched command's handler mutates host domain state that other packages project into the next request (the /plan handler flips plan mode, whose owning package injects its plan:policy system-prompt section), while the command line itself, the detached result, and every menu/notice rendering stay client-side and never enter the session log.
KV Cache effect
None directly; this package neither assembles nor sends a provider request. Command handlers it triggers may change what the owning host packages contribute to the next request's system prompt (a section appearing or disappearing replaces earlier request tokens and invalidates the provider prefix from that point), but that effect is owned and documented by each command's host package.
Known Limitations and Deferred Work
- Detached-result notices fall back to the console off-session — the fire-and-forget paths route results to the triggering session's composer via
SessionInput.notify; after session teardown the console line is the only remaining surface.
