…elector Introduces the core.output dock panel and the ctx.log logging API so extensions can write structured, per-channel output visible in the UI. **Output panel (core.output)** - New `OutputPanel` dock panel with channel selector, level filter, text search, clear button, and auto-scroll toggle - Channel dropdown groups entries into three sections: host channels (Notifications, Application — no header), Built-in Extensions (first-party silo.* extensions, trusted), and Extensions (third-party) - Grouping is driven by a `builtin` flag threaded from `registerChannel` through `OutputChannelState`; key-prefix alone is insufficient because runtime-loaded silo.* extensions from the external repo share the same `ext:silo.*` prefix **ctx.log / LogService SDK API** - New `LogService` type (`packages/sdk/src/output-service.ts`) with `debug/info/warn/error/show/clear`; exported from the SDK barrel - `createContext` wires `ctx.log` for every extension: `core.*` share the `silo:application` channel; all others get a per-extension `ext:<id>` channel that is auto-removed on deactivation - `registerChannel` now accepts an optional `builtin` flag so the panel can correctly group first-party vs third-party channels **Host / extension loader logging** - `extHostLog` (`silo:extension-host` channel) replaces all `console.*` calls in `builtins-registry.ts` and `extension-loader.ts` - Activation, deactivation, enable/disable, load/unload, and dispose errors now appear in the Extension Host output channel **Notifications mirrored to Output** - `ctx.ui.notify` now also writes to the `silo:notifications` channel so users can review dismissed toasts in the Output panel **Application channel lifecycle events** - `core.workspaces` subscribes to workspace state and logs activated, created, closed, and reopened events to the Application channel - `core.themes` logs theme-change events to the Application channel **Git command logging (silo.git)** - Read-only git commands (status, log, diff, show) log at `debug`; write commands log at `info`; non-zero stderr logs at `error` **openSingletonPanel layout API** - New `LayoutService.openSingletonPanel` creates at most one panel per kindId (focuses existing if present); used by `ctx.log.show()` **Status bar ordering fix** - Right-side status items now sort descending so lower priority anchors to the right edge (mirrors the left-side ascending convention) - Corrected priorities: updates (-2), theme (-5), settings (-10), panel-toggles (-20); documented the convention in SDK types Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
