Task 4 Report: Channel Content Templates And Object Inspector

Status

Implemented and committed the Task 4 workbench channel templates and object inspector.

Added ChannelContent.svelte, which dispatches ProjectWorkspace data to the selected system or custom channel template.
Added seven channel templates for overview, inbox, tasks, AI sessions, notes and sources, cron plans, and external custom links.
Made all applicable records selectable through an Inspect <title> action that supplies an InspectorItem to the workbench.
Added ObjectInspector.svelte with Discussion, Properties, and More tabs, including empty-state behavior and object properties.
Wired the selected channel and selected inspector item into ProjectWorkbench.svelte.
Added the required channel dispatcher test, including the task-to-inspector callback assertion.
Kept visual-system CSS untouched for Task 5.

Added apps/web/src/features/workbench/ChannelContent.test.ts before creating any production channel component.
Ran npm test -- --run src/features/workbench/ChannelContent.test.ts from apps/web.
Observed the expected red failure: Vite could not resolve ./ChannelContent.svelte because it did not exist.
Implemented the dispatcher and channel components, then ran the focused channel and workbench tests.
Corrected the inspector tab semantics after the green run exposed Svelte accessibility warnings, then reran verification with no warnings.

npm test -- --run src/features/workbench/ChannelContent.test.ts src/features/workbench/ProjectWorkbench.test.ts
- Passed: 2 test files, 4 tests.
npm run build
- Passed: Vite production build completed successfully.
git diff --check
- Passed: no whitespace errors.

Confirmed every WorkbenchChannel type has a dedicated rendered template through the dispatcher.
Confirmed the custom link uses the required Open external channel text and provides a copy-style action.
Confirmed task inspection produces the exact task title required by the test.
Confirmed the inspector remains visible through its existing aria-label and exposes semantic tab state using role="tab" with aria-selected.
Confirmed no React, shadcn/ui dependency, or index.css modification was introduced.
Confirmed unrelated existing .superpowers/sdd files were not staged.

The copy URL and inspector More-tab actions are present as MVP UI controls; beyond writing the custom URL to the clipboard, they intentionally do not persist or mutate workbench data.
Visual styling is limited to semantic class hooks by design; Task 5 owns the visual-system CSS work.

Replaced the incomplete ARIA tabs pattern in ObjectInspector.svelte with ordinary pressed view-switcher buttons, removing tab and tablist roles that required a full tab-panel keyboard interaction model.
Extended ProjectWorkbench.test.ts to select the Work Plan channel, inspect a task, and assert the rendered inspector title plus Properties values within the object inspector.
Focused workbench coverage passed after the changes: 2 test files, 5 tests.
