 ## [Unreleased]
 
+## [1.18.1] - 2026-08-04
+
+- **Providers:** signing in to an OAuth-only provider now actually completes — the browser login is stored and the provider list updates instead of remaining signed out. OAuth-only providers show a Connect flow instead of an API key form, and their models stay hidden until you are signed in.
+- **Sessions:** archived sessions can now be restored to the active list — from the sidebar context menu, the archived-sessions page, or the bulk-selection bar — instead of only offering permanent deletion (thanks to @makeittech).
+- Walkthrough: models without a working provider login no longer appear in the walkthrough picker, and Generate stays disabled until a usable model is selected instead of failing with a raw provider error.
+- Providers: sign-ins that need extra details (such as GitHub Copilot Enterprise) now ask for them before opening the browser, and device codes come with a working copy button.
+- Walkthrough: connecting to a server older than the app now says the server needs updating instead of showing a raw HTML parsing error, and the "Critical" tag is now "Key change" with a tooltip so it no longer reads as a problem found in your code.
+- Chat: Ctrl/Cmd+L now adds the selected text to the chat input, or focuses it when nothing is selected; the toggle-sidebar shortcut moved to Ctrl/Cmd+Alt+L.
+- Chat: a manually chosen model now stays selected after a delegated subtask finishes, instead of reverting to the agent's default model.
+- Agents/CLI: sending a prompt that never reaches its session is now reported as failed, and an unavailable model, agent, or variant is rejected with a clear error before anything is created.
+- Desktop/Linux: "Open in Terminal" no longer launches a non-terminal app that is set as the terminal launcher (thanks to @kydorn).
+
 ## [1.18.0] - 2026-08-04
 
 - **Walkthrough:** a new guided walkthrough reorders a diff into a sequence of stops — the model groups related changes, explains what each one does, and orders them so each builds on the last. Start one from the Changes and pull-request views for uncommitted work, a branch against its base, or a pull request; nothing runs on its own. Walkthroughs are written in your interface language by default, and the panel can generate one in any other supported language.

+## Wie ein Stop markiert ist
+
+Jeder Stop benennt sein Thema, erklärt es in ein bis zwei Sätzen und zeigt danach genau den Code, den er beschreibt. Manche Stops tragen eine kleine Markierung neben dem Titel:
+
+| Markierung | Bedeutung |
+| --- | --- |
+| **Kernänderung** | Dieser Stop trägt die eigentliche Änderung oder den größten Teil ihres Risikos. Lesen Sie ihn genau und zuerst. |
+| **Kontext** | Eine unterstützende Änderung, damit der Rest verständlich bleibt. Kann überflogen werden. |
+| *(ohne Markierung)* | Ein gewöhnlicher Schritt in der Lesereihenfolge. |
+
+Die Markierung sagt, **wo Sie Ihre Aufmerksamkeit investieren sollten**, und nichts über die Qualität des Codes. Ein Stop wird nie markiert, weil darin etwas Falsches gefunden wurde — das Walkthrough meldet keine Funde, keine Schweregrade und keine Urteile. Wenn Code bewertet werden soll, ist das die Aktion **Review** in [Git & GitHub](/git/).
+
+Die einzigen Markierungen, die tatsächlich auf ein Problem hinweisen, sind **Veraltet** und **Nicht abgedeckt** — und beide betreffen das Veralten des Walkthroughs selbst, nicht Ihren Code. Siehe unten.

+## Loops: scheduled tasks as markdown files
+
+A **loop** is a scheduled task defined as a portable markdown file you can commit to your repo. Drop a file into `.agents/loops/` and the task appears on the next sync — no dialog needed:
+
+```markdown
+---
+name: daily-digest
+schedule: "0 9 * * *"
+enabled: true
+model: anthropic/claude-sonnet-4-5
+agent: plan
+timezone: Europe/Kyiv
+---
+Summarize repository changes since yesterday and post the digest.
+```
+
+### Where files live
+
+- **Project scope** — `.agents/loops/*.md` in the project directory or any ancestor directory up to the git worktree root.
+- **User scope** — `~/.agents/loops/*.md` applies to every project you open.
+
+If a project loop and a user loop share a name, the project loop wins.
+
+### Fields
+
+| Field | Meaning |
+|---|---|
+| `name` | Task name (required, max 80 characters). |
+| `schedule` | Cron expression (required) — loop files are cron-only. |
+| `enabled` | Set `true` to run. Loops are **off by default**, so committing a file never starts running a task on its own. |
+| `model` | `provider/model` (required), e.g. `anthropic/claude-sonnet-4-5`. |
+| `agent` | Agent to use (optional). |
+| `timezone` | IANA timezone (optional, defaults to the server zone). |
+| body | The execution prompt (required). Can be a slash command, like `/review src/`. |
+
+### How loops behave
+
+- The **file is authoritative** while it exists: edits made in the UI are reverted on the next sync. The scheduled-tasks dialog marks loop tasks and disables their edit/enable/delete actions — **run now** still works. To stop a loop, delete the file (or set `enabled: false`).
+- Runtime state (last run, next run, status) lives in the project config and is never written back into the markdown file.
+- Renaming the `name` field renames the task in place. If a loop file temporarily fails to parse (mid-edit, merge conflict), its task is kept with the last good definition until the file is fixed.
+- `daily`/`weekly`/`once` schedules and goal settings remain UI-only; loop files are always cron.
+
 ## What success looks like
 
 After a run, the task shows when it last ran, whether it succeeded, and a link to the session it created. If a run fails, the error is shown there too.

+## How a stop is marked
+
+Each stop names what it is about, explains it in a sentence or two, and then shows exactly the code it describes. Some stops carry a small tag next to the title:
+
+| Tag | What it means |
+| --- | --- |
+| **Key change** | This stop drives the rest of the change, or carries most of its risk. Read it closely and read it first. |
+| **Context** | A supporting change, included so the rest makes sense. Safe to skim. |
+| *(no tag)* | An ordinary step in the reading order. |
+
+The tag is about **where to spend your attention**, not about the quality of the code. A stop is never marked because something was found wrong in it — the walkthrough reports no findings, no severities, and no verdicts. If you want code judged, that is the **Review** action in [Git & GitHub](/git/).
+
+The only marks that do report a problem are **Outdated** and **Not covered**, and both are about the walkthrough itself going out of date rather than about your code — see below.

 - Every other tool, including search/fetch, OpenCode built-ins, custom tools, plugins, and MCP tools, is **expandable** and renders through `ToolPart`.
 - The managed `openchamber` plugin tool uses the expandable path and hides its broad protocol input. The plugin supplies the selected action's human description as the native tool title; the UI renders that metadata without owning an action map. The full versioned result envelope renders through the same neutral JSON summary/tree/raw views as other tools, without a tool-specific output card.
 - `ToolPart` defers expanded content after a user toggle, preventing large tool input/output payloads from mounting during the initial chat render.
+- The rich tool diff preview lives in `ToolPartDiffPreview.tsx` and is lazy-loaded from `ToolPart`. It is the only tool-card piece that imports the `@pierre/diffs` + Shiki rendering stack, keeping that stack out of the eager chat startup graph. While its chunk loads (first rendered diff only) the plain-text patch from `PlainDiffFallback.tsx` renders as the Suspense fallback, mirroring the preview's error fallback. `ToolPart` itself must not statically import `@pierre/diffs` runtime modules or `@/lib/shiki/appThemeRegistry`.
 - Running bash output falls back to `state.metadata.output` until canonical `state.output` arrives. Its fixed-height output viewport follows new output until the user scrolls up, then resumes following when the user returns to the bottom. Live output appends or replaces rewritten snapshots as plain text without worker highlighting; finalized output normalizes ANSI terminal controls with a bounded synthetic-cell budget, bypasses the throttle, and receives the normal one-time highlighted rendering.
 - Thinking/Justification duration is hidden in `sorted` mode (handled in `ReasoningPart.tsx` + `JustificationBlock.tsx`).

 - Layout (web/desktop): top navigation (`SidebarNav`: New session, Scheduled, Multi-run, Archive), then the `recent` zone, then one zone per project with a **flat** session list. There is no rendered worktree grouping level.
 - **Two grouping display modes** (`useSessionDisplayStore.sessionGroupingMode`, toggled in the view dropdown): `'by-worktree'` (default) renders the worktree-grouped `sectionsForRender` with slim PR-aware branch sub-headers inside each project zone; `'flat'` renders `flatSectionsForRender` — one merged non-archived group per project (`id: 'flat'`, `folderScopes` listing every contributing scope) with per-row branch markers. Both derive from the same `projectSections` data layer, which alone feeds bootstrap demand planning and PR polling.
 - When sticky zone headers are enabled, project headers are sticky "zone" bands (`SortableProjectItem`); on a vibrant desktop the scrolling content fades behind an unmasked, non-interactive copy of the stuck icon/title without painting a background. The transparent fade zone blocks interaction with obscured rows. The `recent` section uses the same overlay while it is the leading sticky header. Collapsed projects show an aggregated busy/unseen indicator (`ProjectAggregateStatusIndicator`), derived from the live status index and notification store scoped to the project's directories.
+- **Activity is a dot plus a counter, never a spinner.** The row's left gutter shows a static dot — primary while the session runs (`busy`/`retry`), info while it is unread — and the metadata slot on the right swaps the goal/branch/date group for the elapsed time of the turn (`SessionActivityDuration`, ticking once per second). The readout takes the dot's color in each state — primary while running, info once it is waiting to be read — so the pair reads as one indicator. A running spinner repainted a composited layer per row every frame for the whole turn; the counter conveys the same "something is happening" at 1 fps. The counter follows the unread marker's lifetime exactly: it survives the turn ending, disappears when the session is read, and never lingers on the session being watched (which is marked read as it goes idle). Aggregate indicators for collapsed groups, folders, and projects show the dot only — a group may hold several running turns, so a single counter would have nothing to count. The same treatment applies to the mobile sessions sheet and session switcher rows. The worktree-move indicator stays a spinner: it marks a short user-initiated operation, not a session state.
 - Session rows have a single layout (former `minimal`); the `default`/`minimal` display mode was removed (`session-display-mode` store v4 migration drops the key). Rows show an inline branch label (from `node.worktree` or recent's `secondaryMeta`) when the session lives outside the project root, and bold titles while unread.
 - Folders render **flat** after the loose sessions: nested folders keep `parentId` in the data model but display at one level with a "Parent / Child" path label (`SessionFolderItem.displayName`); collapsing a folder hides its whole subtree. Folder actions resolve their owning scope per folder entry (folders from multiple worktree scopes can coexist under one project).
 - Archived sessions are not shown in the web/desktop sidebar; the Archive page (`ArchiveView`, `useUIStore.isArchivePageOpen`) replaces the old toggle. VS Code keeps inline archived buckets behind `showArchivedSessions` (compact webview has no page surfaces). Restore (unarchive) is available per session (row context menu, Archive page row) and in bulk (selection bar) and writes `time.archived = 0` — the server cannot clear the field over HTTP, so the global session cache splits active/archived client-side (see "Restore (unarchive) contract" in `sync/DOCUMENTATION.md`).

 - Recent membership includes active root sessions immediately even when their last committed `time.updated` falls outside the 48-hour window. Children and archived sessions remain excluded, and inactive roots remain timestamp-based. The active-ID subscription is disabled while the sidebar is hidden and ignores retry/status detail changes, avoiding streaming-frequency rerenders.
 - Structural updates rebuild grouped nodes only for projects whose local sessions, worktrees, repository state, or branch changed; unchanged project sections preserve references so memoized group/session descendants skip the update wave.
 - Empty successful lists, unresolved loads, and failed loads are separate UI states. Failed groups expose Retry and retain prior data.
+- Directory permission failures remain visible even when stale sessions are retained. Flat groups inspect every represented root/worktree directory; local Desktop may open the native picker for the exact failed directory, while other runtimes keep the ordinary Retry action.
 - Pins and folder assignments are not pruned from the first startup snapshot or from optimistic mutations. Confirmed local deletion and routed external deletion clean immediately; a later authoritative omission after an established baseline covers missed external delete events.
