Review found the `onTasksChanged` teardown reasoning inverted. The comment claimed every registration is an effect on the registry's own fiber, so listeners would be gone before service disposal empties the store — but the traceable proxy rebinds `this.ctx` to the CALLER, which this package's own HMR-safety test already proves. The only shipped consumer registers from the api-proxy mux stream, so it was still listening and simply kept the rows it last received. Service disposal now announces the emptied set, and teardown announces its stopping transition immediately instead of leaving an observer on `running` for however long a slow producer takes to release. Two documentation claims were false in the opposite direction: the Agent Note and the ui-task README both said an unowned task is invisible in the header, while `list(caller)` returns unowned tasks to every caller, the carrier fans their changes out to every subscribed session, and this PR's own test asserts exactly that. The note even contradicted itself two sections earlier. Both sides now state the real asymmetries — another session's tasks, and the process-local registry emptying on restart. The "no Web path calls the consuming `ctx.tasks.read()`" invariant claimed a test that did not exist; the carrier suite's producer had no `readOutput` at all, so a stray read would have failed nothing. Its producer now counts cursor consumption and the lifecycle and baseline paths both assert zero. Also: a session created after the mux opened now receives the task baseline it missed, the popover samples its clock when it opens rather than at mount, and a failed task's unbounded producer detail elides instead of widening the row.
client/ — web-GUI browser half

Each child reference owns its contract and detailed behavior. The slot system standard and web client architecture note own the cross-package composition and loading decisions.
The subsystem reference is client-modules.md; the slot system standard is the definitive slot model, and the web client architecture note owns the loading chain and object layer.
