 # Changelog
 
+## [0.37.18.0] — 2026-03-24
+
+### Summary
+
+Debug/Model surface rebuild + workspace bridge. Debug modal converted from
+673 lines of imperative DOM JS to a Preact component tree (CR P2-5). User
+default workspace auto-created on first access. Tool outputs auto-save file
+refs linked to assistant messages. "Save to workspace" action on chat code
+blocks. Model selector shows provider health dots. Provider "Test Connection"
+buttons added to both BYOK and admin UIs.
+
+### Added
+
+- **Debug modal Preact rebuild:** Engine singleton (`debugEngine`) with
+  subscribe() pattern for reactive updates. Component tree: ConsoleTab,
+  NetworkTab, StateTab, ReplTab, DebugBadge. `sw-debug.css` extracted from
+  `modals.css`. `debug.js` reduced from 673 to ~40 lines (thin bootstrap).
+  `repl.js` absorbed into `repl-tab.js`. (`src/js/sw/components/debug/`)
+- **Default user workspace:** `GET /workspaces/default` auto-creates a
+  "My Files" workspace per user on first access. Idempotent. Route wired
+  before `:id` param. SDK: `sw.api.workspaces.getDefault()`.
+  (`server/handlers/workspaces.go`, `server/main.go`)
+- **tool_output auto-save:** When `workspace_write` or `workspace_patch`
+  tools succeed during completion, a file ref with `origin=tool_output` is
+  recorded in the `files` table, linked to the assistant message via
+  `message_id`. (`server/handlers/tool_loop.go`, `completion.go`)
+- **Origin filter on channel files:** `GET /channels/:id/files?origin=`
+  query param. SDK: `sw.api.channels.files(id, {origin})`.
+  (`server/handlers/files.go`)
+- **Save-to-Workspace bridge:** Save button on assistant messages with code
+  blocks. Saves to user's default workspace with auto-generated filenames.
+  `guessExtension()` utility (37 language mappings). (`message-actions.js`,
+  `message-bubble.js`, `code-block.js`)
+- **Model selector health dots:** Provider health status (green/yellow/red)
+  shown next to model names in chat selector. Admin-only, graceful degrade
+  for non-admin. (`model-selector.js`)
+- **Provider test buttons:** "Test Connection" in Settings BYOK and "Test"
+  in Admin providers. Calls `fetchModels()` and shows success/failure toast.
+  (`settings/providers.js`, `admin/providers.js`)
+
+### Changed
+
+- `modals.css`: Debug-specific rules moved to `sw-debug.css` (~22 rules).
+- `base.html`: 46-line debug modal HTML block replaced by `<div id="debugMount">`.
+- `sw.js`: Service worker cache list updated (repl.js removed, sw-debug.css added).
+- `LoopResult` struct: new `FileRefs` field for tool file output tracking.
+- `channels.files` SDK method: now accepts optional opts for query params.
+
+### Removed
+
+- `src/js/repl.js` (527 lines) — absorbed into Preact `repl-tab.js`.
+
+### ICD / OpenAPI / SDK Test Runner
+
+- ICD: `GET /workspaces/default` documented; tool_output creation behavior updated.
+- OpenAPI: `/api/v1/workspaces/default` endpoint added.
+- SDK runner: 2 workspace tests (getDefault + idempotent), 1 channel files origin filter test.
