Goal surface plugin, browser half: the `GoalBar` strip is the first standalone card in the `conversation.input.dock` composer-context stack (order 0, before Todo and Queue). The live goal arrives through `useProjection('goal')` — the host-computed whole value seeded by the history tail page and updated by `session/projection` frames — so the plugin owns no store, no refresh chain, and no event listener. The slot inject face carries only the four mutation verbs (edit / pause / resume / clear over the `goal.*` wire domain — an active goal offers the pause action, a paused one resume); each reads the CAS ref from the session's current projected value at call time and surfaces the settled RPC error inline (the RPC's compare-and-set is the staleness guard — there is no client fence). Goal creation stays on the `/goal` host command; loading, absent, and completed goals render nothing.

The strip single-flights mutations synchronously because React's pending render cannot fence same-frame clicks; after a successful clear it immediately suppresses that exact goal id while the authoritative null projection catches up. Goal creation stays on the `/goal` host command; loading, absent, completed, and successfully cleared goals render nothing.
The `/client` export surface is the plugin body (`apply`/`inject`), the `GoalBar`/`GoalDock` components, and the injected verb face types.

## Known Limitations and Deferred Work
- **Durable phase only** — the projection value deliberately omits process-local activation (armed/disarmed), so the strip cannot distinguish an active-but-disarmed goal from an armed one; resume re-arms through the RPC side. A host-live-value channel is deferred until a real consumer needs it.
- **No keyless snapshot yet** — the assembled-application transcript (boot → projection → GoalBar) is deferred to the post-review cleanup pass recorded on the landing PR.
