+- Z.ai Coding Plan exposes separate 5-hour and weekly token/credit limit entries plus a monthly `TIME_LIMIT` for MCP tools. The API renamed the limit type from `TOKENS_LIMIT` to `CREDIT_LIMIT` (same `unit`/`number` window semantics); `CREDIT_LIMIT` entries additionally carry `usage` (total), `currentValue` (consumed), and `remaining`, surfaced as a credit `valueLabel`, and the payload's `data.level` becomes `planLabel`. Web and VS Code must preserve these windows and stay in sync.

Subject: [PATCH 05/59] feat(chats): add managed projectless chat sessions

Create projectless chat sessions under a managed, date-scoped Chats directory and clean abandoned or deleted session folders.

Add Chats to sidebar state, startup cache, shared context, and Electron Mini Chat while keeping VS Code project-only. Resolve managed chat directories to one server-side memory owner and document the runtime contracts.

 ## Native Features Owned Here
 
 - Floating Mini Chat windows.
+- New Mini Chat windows default to the managed Chats target. Explicit project/worktree drafts retain their target, existing managed chat sessions reopen in their own directory, and the compact header omits project/branch metadata for Chats. Opening a managed draft back in the main window preserves that target.
 - Multiple native windows.
 - Native notifications.
 - User-confirmed local folder selection. The shared UI supplies the requested directory as the picker `defaultPath`; confirmation is required before filesystem access is retried.

+- `SidebarActivitySections.tsx`: Global top section renderer for project-only `recent` sessions followed by OpenChamber-managed `chats`, styled as zone headers.
 - `SidebarFooter.tsx`: Static footer with icon-only settings, shortcuts, and about actions.
 - `SidebarProjectsList.tsx`: Main scrollable renderer for project zones and their flat/archived groups plus empty/search states; owns project drag-to-reorder.

 ## The golden rule
 
+### Managed chat directories
+
+Ordinary user-created drafts default to the OpenChamber-managed Chat target. The first submit creates one isolated directory under `~/.config/openchamber/chats/YYYY-MM-DD/session-<id>` before creating the OpenCode session. The shared `~/.config/openchamber/chats` root acts as a system project owner for sidebar membership and Notes, Todo, Plans, pinned knowledge, and project memory, but it is never persisted or rendered as a user project and exposes no Git/worktree controls. Project and worktree actions remain explicit targets. Archiving retains a chat directory so restore remains lossless. Confirmed deletion removes that managed directory and never removes project directories.
+
+Typing the first character in a managed Chat draft starts one deduplicated directory preparation for that draft. Materialization consumes the prepared directory before `createSession`, removing filesystem creation from the usual submit path. Closing the draft, changing it to a project target, or completing preparation after the runtime/draft changed deletes the unclaimed directory. A create failure also deletes the consumed directory.
+
+The global sessions store persists and hydrates one bounded, runtime-scoped startup snapshot containing only active managed chat sessions. Every global session surface, including the main sidebar and Electron Mini Chat switcher, sees that stale snapshot while the global list is unresolved or failed; the first authoritative global snapshot replaces it. Runtime reset to idle must hydrate rather than erase the destination runtime's snapshot; authoritative empty, archive, and delete updates do persist the resulting empty or reduced list.
+
+VS Code intentionally has no managed Chats mode. It neither reads nor writes the managed Chats startup cache, regular drafts continue to target the open workspace, and the global session store rejects managed chat sessions from both snapshots and live upserts before any VS Code surface can consume them. Sidebar and switcher filters repeat that exclusion defensively.
+
 When creating a draft in `handleDirectoryEvent`, **only clone the state fields the event will mutate**. Never spread all fields eagerly.

Track Chats and Recent section sentinels so the desktop sticky overlay changes identity only when the corresponding section reaches the top of the sidebar.

 - `SidebarHeader.tsx`: Top header UI for add-project, session search, selection mode, project sort, and the display menu (recent toggle, collapse/expand all).
 - A successful add/create/clone from the project-directory dialog transitions to a new-session draft targeted at that project, matching the project's `+` action; changing project metadata alone must not leave the visible session or draft on a different directory.
 - `SidebarNav.tsx`: Text navigation rows above the tree (New session, Scheduled, Multi-run, Archive); hidden in VS Code.

+- `SidebarActivitySections.tsx`: Global top section renderer for OpenChamber-managed `chats` followed by optional project-only `recent` sessions, styled as zone headers. The desktop sticky identity overlay follows the activity header whose sentinel has crossed the scroller edge, so a small scroll cannot relabel Chats as Recent.
 - `SidebarFooter.tsx`: Static footer with icon-only settings, shortcuts, and about actions.
 - `SidebarProjectsList.tsx`: Main scrollable renderer for project zones and their flat/archived groups plus empty/search states; owns project drag-to-reorder.
 - `SessionGroupSection.tsx`: Renders one flat (or archived) group: sessions first, then flat folder entries with path labels, show-more batching, and explicit loading/error/retry state for empty groups. Archived buckets (VS Code) virtualize past 50 rows.

 - `SessionSidebar.tsx` now acts mainly as orchestration; core logic moved to focused hooks/components.
 - 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.
+- **Project display is independent from grouping.** `'all'` keeps every project zone; `'single'` is web/desktop/PWA-only and renders one selected project under the always-present Chats section. Its project header is a non-collapsible picker ordered by the current project sort. Recent and collapse/expand-all controls are hidden without changing their persisted preferences. Opening a materialized project session updates the picker from the session's confirmed directory; changing only a draft target does not. In `'single'` + `'flat'`, active sessions reveal in batches of 20. `'single'` + `'by-worktree'` retains the ordinary per-group limits. Project display mode, session grouping, project sort, and the Recent preference are server-backed shared settings with the hydrated browser store as the migration/failure cache. The selected single project and sticky-header preference remain device-local.
 - 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.

 Project ordering defaults to manual. Session display persistence v3 migrates the previously shipped `recent` project order to `manual` while preserving every other explicit sort mode.
 
+Session display persistence keeps a hydrated local cache for the independent all-projects/single-project mode, session grouping, project sort, and Recent preference; successful server settings snapshots are authoritative and the UI seeds missing server fields once from that cache for upgrades. The last confirmed or manually selected project and sticky-header preference stay local to the device. Draft target changes do not write the picker selection; materialized session navigation updates it from the resolved project directory.
+
 Session folders persist in runtime-specific v2 browser keys without silently evicting older runtime namespaces. Runtime switch, page hide, app freeze, and unload synchronously flush the pending browser snapshot before lifecycle suspension or namespace replacement. A runtime switch then cancels stale old-runtime disk work and starts generation-owned disk hydration. Missing or malformed server files are not authoritative empty snapshots; disk data may replace browser state only when it carries a real revision and no newer local folder mutation occurred. Server writes are serialized and reject non-newer revisions so delayed or duplicate requests cannot overwrite the current state. File-search cache and in-flight keys include runtime plus directory and are cleared on endpoint reset.
 
 Persisted session todos use a bounded composite key of runtime, normalized directory, and session ID. Ambiguous legacy todo entries are discarded rather than claimed by whichever runtime starts first. Authoritative deletion uses an explicit runtime identity, and session-folder deletion scans every scope in the active runtime so archived assignments cannot survive after their session is gone.

Subject: [PATCH 10/59] fix(chats): align folders and session actions

Render managed Chats through the shared folder-aware session group and keep folder ownership at the Chats root, including new drafts and older per-directory scopes.

Hide worktree actions for Chats, make worktree shortcuts inert on Chat drafts, and let new-session shortcuts inherit an active session directory while explicit Chats controls still create managed Chat drafts.

 - Scheduled tasks (`ScheduledTasksDialog`, now a full-page surface on web/desktop) and per-project worktree management (`WorktreesView`, opened from the project menu) render as overlays inside `<main>` in `MainLayout`; the sidebar no longer mounts them.
 - Group-level PR-status polling/indicators and worktree-group drag-to-reorder were removed together with the worktree grouping level; `oc.sessions.groupOrder` is no longer read or written. Worktree PR/branch context lives in the Worktrees surface.
 - Root session menus can quickly create a worktree from the session directory's current branch and move the full session subtree there while idle.
+- Managed Chats never offer the worktree-move action in either the sidebar row menu or the active-session header menu because their directories are not project repositories.
+- Managed Chats use the shared Chats root as their folder scope. Their activity section renders the normal folder tree, and sessions created from a Chats folder are assigned back to that root-scoped folder after their date/session directory materializes. Per-session folder scopes created by older builds remain visible for compatibility.
+- The New session keyboard command inherits the active materialized session directory. Explicit sidebar entry points, including the top New session row and the Chats `+`, open a fresh managed Chat draft instead.
+- The new-worktree keyboard command is a silent no-op while a managed Chat draft is open. It must not retarget that draft to the active project or show a Git/worktree error because Chats never participate in worktrees.
 - Directory loading is demand-driven: the sidebar publishes one complete priority plan for all known project/worktree directories, while the sync layer owns bounded execution.
 - When multiple configured projects are checkouts of the same Git repository, exactly one project owns the shared worktree topology: the configured canonical primary root when present, otherwise the first configured source for that repository. Any worktree path that is also a configured project is omitted from subordinate worktree groups, so every directory has one sidebar location while remaining part of bootstrap demand.

Subject: [PATCH 13/59] fix(ui): scope file-reference stat probes to the
 session directory (#3022)

* test: add regression test for stat directory scoping (#3019)

* fix: scope file-reference stat probes to the session directory (#3019)

The /api/fs/stat probe sent by the markdown renderer carried no
directory hint, so the server resolved the workspace from
settings.lastDirectory. When the browsed directory differs from the
session directory the stat returns 400 and the renderer treats it as
file-does-not-exist, silently disabling file-reference links.

Send effectiveDirectory as x-opencode-directory on the probe and
qualify the stat cache key by directory so a rejection under one
directory cannot leak into another. The probe logic moves from
MarkdownRendererImpl into fileReferenceStat with unit coverage.

Subject: [PATCH 14/59] feat(ui): show externally-created sessions in sidebar
 and Recent view (#2930)

* feat(ui): show externally-created sessions in sidebar and Recent view (#1441)

Sessions created by external OpenCode processes (CLI, other server
instances) share the same database but don't broadcast SSE events to
OpenChamber's connected server. The existing 45s global polling via
experimental.session.list() already discovers these sessions, but the
isKnownActiveSessionDirectory filter in SessionSidebar.tsx removes
them when their directory isn't a registered project.

Add effectiveKnownDirectories that extends knownSessionDirectories
with directories derived from globalActiveSessions themselves, so
external sessions pass the filter and appear in the sidebar and Recent
view.

Validated with two live OpenCode server processes sharing the same
database: global experimental.session.list() returns external sessions
immediately, while per-directory APIs do not.

* Revert "feat(ui): show externally-created sessions in sidebar and Recent view (#1441)"

This reverts commit 94acda43ad3049e7674d8eb3f24b1f74acb0d1c3.

* fix(ui): make sidebar reactive to global session store updates (#1441)

Replace non-reactive useGlobalSessionsStore.getState() with direct
reactive subscriptions for activeSessions and archivedSessions. The
previous getState() pattern relied on proxy subscriptions
(activeSessionStructure, hasAuthoritativeGlobalSessions) to trigger
re-renders, which created a fragility gap where store updates could
go unnoticed by the sidebar.

Add a 45s periodic refreshGlobalSessions() interval in the sidebar,
independent of the tray sync hook. The tray sync's polling is gated
behind isTrayPlatform() and isTrayEnabled(), so on runtimes where
the tray is unavailable, there was no periodic refresh of global
sessions at all. External sessions (created by CLI or other server
processes) were only discovered on initial mount or page refresh.

 - 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.

Subject: [PATCH 20/59] feat(diff): add branch scope to context panel diff view

Show every change on the current branch relative to its base in the
Changed/Staged/Last turn dropdown. The base comes from the branch's
reflog record or an explicit per-branch user choice (persisted), never
a main/master guess; when git has no record the user picks a base once
from a searchable branch list.

- server: GET /api/git/branch-base (reflog-derived base),
  GET /api/git/range-files (name-status -z with rename/copy
  destination paths and -C copy detection)
- shared UI: optional getBranchBase/getGitRangeFiles runtime APIs
  with boundary parsing; persisted per-branch overrides keyed by
  runtime+directory+branch
- DiffView: branch scope with confirmed-unavailability coercion of
  persisted tabs (detached HEAD, default-branch checkout, metadata
  settled without a default), range-invalidated diff cache guarded
  against stale completions, bounded branch-metadata retry, read-only
  diff actions in branch scope; hidden in VS Code
- helper module branchDiffScope.ts with tests for coercion,
  availability, race conditions, and retry exhaustion

 # Інтеграції
 
 Інтеграція — це невеликий плагін, що додає провайдера до OpenChamber на основі підписки, яка в вас уже є. Керувати ними можна в **Settings → Integrations**.
 
-> **Експериментальна функція:** інтеграції можуть змінюватися або перестати працювати. Використовуйте їх на власний розсуд.
-
-Ми розробили ці інтеграції так, щоб вони використовували передбачені провайдерами способи входу й не порушували відомі нам умови користування. Ми не можемо гарантувати, що провайдер прийме кожен спосіб використання або кожен обліковий запис. Ознайомтеся з умовами провайдера й використовуйте інтеграції на власний ризик. OpenChamber не може вирішувати обмеження, блокування облікових записів або суперечки з провайдером.

 - **Claude Code** — ваша підписка Claude Pro або Max, без API-ключів

 **Як захищається ваш обліковий запис Claude:** ця інтеграція використовує офіційний Claude Agent SDK від Anthropic і ваш встановлений Claude Code CLI. Вона не перехоплює OAuth, не витягує й не відтворює браузерні токени, не видає себе за непідтримуваний клієнт і не обходить процес автентифікації Anthropic. Усе працює через підтримуваний Anthropic шлях доступу, тож інтеграція не несе ризику блокування облікового запису, пов'язаного з перехопленням токенів або несанкціонованими способами автентифікації.

 集成是一个小型插件，它使用你已有的订阅为 OpenChamber 添加一个提供商。你可以在 **Settings → Integrations** 中管理它们。
 
-> **实验性功能：**集成可能会变更或停止工作。请自行酌情使用。
-
-我们设计这些集成时，力求遵循提供商预期的登录流程，并避免已知的服务条款违规。我们无法保证提供商会接受每种使用方式或每个帐户。请查看提供商的条款，并自行承担使用集成的风险。OpenChamber 无法处理提供商施加的帐户限制、暂停或争议。
+> **实验性功能。**我们力求遵守提供商的政策，但帐户限制和暂停仍由各提供商决定。请自行承担使用集成的风险。
 
 可用的集成：
 
 - **Claude Code** — 你的 Claude Pro 或 Max 套餐，无需 API 密钥
-- **Command Code** — 你的 Command Code 套餐
 - **Cursor** — 你的 Cursor 套餐的模型额度

Subject: [PATCH 23/59] feat(dictation): transcribe after recording instead of
 live

Parakeet is an offline model trained on whole utterances, so re-decoding
the growing buffer to animate a live transcript cost O(n^2) work for a
result the final decode replaced. Sessions now decode once per committed
segment, and the composer shows a scrolling waveform of the mic level
instead of running text.

Long dictations split at a pause once past 60s (hard cap 90s) instead of
on a blind 15s timer, so cuts no longer land mid-word. Committed segments
decode while the user is still speaking: a 185s dictation returns 4.1s
after stop instead of 11.0s, with identical text (816 vs 817 words).

Also fixes two ways the stream manager could silently drop transcribed
audio. It now counts the commits it issued instead of trusting the
session's echoed events, so a commit still in flight when the client
finishes can no longer be left out of the final text. And segment
byte/peak accounting is reset where the commit is issued rather than when
the event arrives, which could mistake the tail of a dictation for
silence and clear it.

 ## [Unreleased]
 
+- **Dictation:** speech is now transcribed after you stop talking, instead of being re-guessed word by word while you speak. The offline models OpenChamber runs are built to read a whole utterance at once, so the running transcript was consistently worse than the final one. While recording, the composer shows a live waveform of your voice and a timer, then Transcribing while the text is produced. Long recordings are split at pauses in your speech rather than on a timer, so a three-minute dictation still returns a few seconds after you stop, and words are no longer cut in half at the split.
 - Chat: if OpenCode restarts while a response is still running, the chat now stops with an interrupted state and a notification to continue instead of hanging silently (thanks to @sum117).

+## Segmentation
+
+A dictation is one segment unless it runs long. Past `segmentMinSeconds`
+(60 s) the manager commits on the first silent chunk, so cuts land at a pause
+rather than mid-word; `segmentMaxSeconds` (90 s) is a hard cap for speech with
+no pause in it. Client chunks are ~1 s, so "silent chunk" is roughly a second
+of silence.
+
+The bounds exist because Parakeet is a full-attention conformer: decode cost
+and peak memory grow quadratically with segment length. Measured on Parakeet
+v3 int8 with 2 threads: 60 s took 2.1 s and +90 MB, 180 s took 9.3 s and
++490 MB, 300 s took 21.3 s and +1.5 GB. Committed segments decode while the
+user is still speaking, so only the tail is left to transcribe on stop.
+
 ## Invariants
 
 - Never load `sherpa-onnx-node` in the main server process.
+- Transcription happens on commit only; sessions never emit non-final
+  transcripts. The `partial` messages a client receives are the concatenation
+  of already-committed segments, and exist so a dictation that fails partway
+  can be salvaged instead of losing minutes of speech.
 - The stream manager acks only the highest contiguous seq; the client is
   expected to retain unacked segments for retry/replay.
 - Silence-only segments (peak < 300) are cleared, never committed, so

Subject: [PATCH 28/59] feat(git): follow repository style when generating
 commit and PR text

Commit generation now samples the last 10 commit subjects and instructs the
model to match their language, prefix convention, and length, falling back to
Conventional Commits only when the history shows no consistent style.

PR generation probes the conventional pull request template locations and
reuses the repository's own sections and checklists as the body structure when
one is found.

 ## [Unreleased]
 
 - **Dictation:** speech is now transcribed after you stop talking, instead of being re-guessed word by word while you speak. The offline models OpenChamber runs are built to read a whole utterance at once, so the running transcript was consistently worse than the final one. While recording, the composer shows a live waveform of your voice and a timer, then Transcribing while the text is produced. Long recordings are split at pauses in your speech rather than on a timer, so a three-minute dictation still returns a few seconds after you stop, and words are no longer cut in half at the split.
+- Git: generated commit messages now follow the style of the repository's recent commits, including their language, so repositories that commit in Korean or without a `feat:`-style prefix get messages that match instead of English Conventional Commits.
+- Git: generating a pull request description now picks up the repository's own PR template when it has one, so the draft comes back in your project's sections and checklists instead of the built-in Summary/Why/Testing layout.
 - Chat: if OpenCode restarts while a response is still running, the chat now stops with an interrupted state and a notification to continue instead of hanging silently (thanks to @sum117).

Subject: [PATCH 29/59] fix(chat): stop the just-sent user message from
 flickering

The server echo of an optimistic user message carries different part
ids, so the reducer dropped the optimistic part and appended the server
one at the end, and MessageBody keyed user parts by part id. The key
change remounted the text subtree (blank frame, markdown re-parse,
truncation state reset) and the append reordered text against file
parts.

Replace the optimistic part in place and key user parts positionally.

Subject: [PATCH 30/59] fix(git): separate generated PR prompt blocks

The additional context and pull request template blocks ran into the file
list without a blank line, and the template's markdown headings blended into
the surrounding instructions. Each block now starts on its own, and template
content is fenced with explicit markers labelled as structure to reuse rather
than instructions to follow.

Subject: [PATCH 32/59] fix(chat): keep long user messages expandable

Truncation was measured once on mount and watched through a ResizeObserver
on the clamped element, whose own height stops changing under line-clamp.
A message measured before its content settled never regained the expand
affordance, and a just-sent one measured before its turn finished laying
out could not be expanded at all.

Measure at click time so expanding depends on whether the text is clipped
right now, re-read once on the next frame after mount, and observe the
children (which keep their natural height) plus subtree swaps.

 ## [Unreleased]
 
-- **Dictation:** speech is now transcribed after you stop talking, instead of being re-guessed word by word while you speak. The offline models OpenChamber runs are built to read a whole utterance at once, so the running transcript was consistently worse than the final one. While recording, the composer shows a live waveform of your voice and a timer, then Transcribing while the text is produced. Long recordings are split at pauses in your speech rather than on a timer, so a three-minute dictation still returns a few seconds after you stop, and words are no longer cut in half at the split.
-- Git: generated commit messages now follow the style of the repository's recent commits, including their language, so repositories that commit in Korean or without a `feat:`-style prefix get messages that match instead of English Conventional Commits.
+- **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.
+- **Skills catalog:** browse curated GitHub skill collections in a card-based catalog with cross-source search, skill counts, stars, recent updates, and links back to each skill's repository.
+- **Diff:** the context-panel diff can now show every change on the current branch against its base branch. OpenChamber detects the base when Git knows it, or lets you choose one once when it does not.
+- **Dictation:** speech is now transcribed after you stop recording. The composer shows a live waveform and timer, and long recordings split at pauses instead of cutting words.
+- Chat: file paths in messages now open from the session's project, even if you last browsed files in another project (thanks to @tomzx).
+- Diff: creating an inline comment now opens the chat and focuses the composer for your follow-up.
+- Providers: expanded support for custom providers.
+- Small Model: summaries, goal audits, commit messages, and walkthroughs now support more providers.
+- Git: generated commit messages now match the repository's recent commit style and language.
 - Git: generating a pull request description now picks up the repository's own PR template when it has one, so the draft comes back in your project's sections and checklists instead of the built-in Summary/Why/Testing layout.
+- Sidebar: switch between the full project list and a focused view of one project. Sessions created outside OpenChamber now also appear in the sidebar and Recent list without a page refresh (thanks to @tomzx).
 - Chat: if OpenCode restarts while a response is still running, the chat now stops with an interrupted state and a notification to continue instead of hanging silently (thanks to @sum117).
+- Chat: newly sent messages and syntax-highlighted code blocks no longer briefly flicker. Bash output can also grow with its content instead of being cut off.
+- Usage: Z.ai credit limits now appear alongside its other quota windows.
+- Git: pull-request checks in Work status stay current as their status changes.
+- UI: the default dialog close button is easier to click or tap (thanks to @rockinrimmer).
+- Desktop/Windows: the close button now aligns correctly with the rest of the window chrome.

 Use `useGlobalSessionsStore` when the UI needs a **shared global session cache**.
 
+Each full app root owns one global polling lifecycle through
+`useGlobalSessionsPolling`. The web/desktop root and VS Code chat root load once
+when mounted and refresh every 45 seconds so sessions created by another
+OpenCode process are discovered without relying on the sidebar or native tray
+being visible. Embedded chats and the VS Code agent-manager panel do not poll.
+The sidebar and tray consume the same store and must not start their own
+full-list timers. Surface-specific refreshes, such as opening the mobile session
+sheet or returning from suspension, may still request freshness at their
+explicit lifecycle edge; the store coalesces an overlapping in-flight load.

 - **Dictation:** speech is now transcribed after you stop recording. The composer shows a live waveform and timer, and long recordings split at pauses instead of cutting words.
 - Chat: file paths in messages now open from the session's project, even if you last browsed files in another project (thanks to @tomzx).
 - Diff: creating an inline comment now opens the chat and focuses the composer for your follow-up.
+- Chat: in the expanded composer, Enter now starts a new line and Cmd/Ctrl+Enter sends, so a long prompt is harder to send by accident.
 - Providers: expanded support for custom providers.
 - Small Model: summaries, goal audits, commit messages, and walkthroughs now support more providers.
 - Git: generated commit messages now match the repository's recent commit style and language.

 - Root session menus can quickly create a worktree from the session directory's current branch and move the full session subtree there while idle.
 - Managed Chats never offer the worktree-move action in either the sidebar row menu or the active-session header menu because their directories are not project repositories.
 - Managed Chats use the shared Chats root as their folder scope. Their activity section renders the normal folder tree, and sessions created from a Chats folder are assigned back to that root-scoped folder after their date/session directory materializes. Per-session folder scopes created by older builds remain visible for compatibility.
+- An empty Chats section says that there are no chats yet; it never reuses the project/workspace empty message.
 - The New session keyboard command inherits the active materialized session directory. Explicit sidebar entry points, including the top New session row and the Chats `+`, open a fresh managed Chat draft instead.
 - The new-worktree keyboard command is a silent no-op while a managed Chat draft is open. It must not retarget that draft to the active project or show a Git/worktree error because Chats never participate in worktrees.
 - Directory loading is demand-driven: the sidebar publishes one complete priority plan for all known project/worktree directories, while the sync layer owns bounded execution.

 `useProjectContextStore.ts` caches server-owned project notes, todos, and plan links, keyed by the path-derived project id. It replaced a pair of `window` CustomEvents that made every mounted notes panel re-read the whole project config. Writes are optimistic and roll back on failure; they are serialized per project, because the server's own store does a read-modify-write and two concurrent saves would otherwise race it. A load that resolves while a write is in flight keeps the local value for that field group only, so a slow snapshot cannot undo newer typing while still delivering the plan list it fetched. A failed load sets `error` and preserves the cached snapshot — an unreachable server must never render as "this project has no notes". Note and plan creation are deliberately not optimistic, since ids and timestamps are assigned by the server. Notes, todos, and plans are written through separate routes and tracked by separate in-flight flags, so a todo toggle cannot clobber a note edit in the same window. Pinned notes and plans are assembled into a synthetic context part by `lib/projectContextPinning.ts` at send time; that module tracks per-session what it already sent so an unchanged pinned set is not re-sent every turn.
 
-`messageQueueStore.ts` keeps a queued message until its own send resolves, so between dispatch and resolution the entry is still visible to every reader. Dispatchers must therefore mark the send (`markSending`/`clearSending`) and read `getSendableQueue()` — or filter `sendingIds` themselves — instead of dispatching straight from `queuedMessages`; otherwise a composer submit merges a message the auto-send hook is already delivering and it is sent twice (the window is seconds over a relay). `clearQueue()` retains in-flight entries for the same reason. `sendingIds` is deliberately not persisted: a restart has no in-flight sends, and a stale flag would strand a queued message.

Desktop queues use the configured host id as runtime identity, not the current API URL, because an SSH reconnect allocates a new local forwarding port while the remote host remains the same.
 
 `useGlobalSessionsStore.ts` owns cold/global active and archived session coverage, including `sessionsByDirectory`. It is complementary to directory child stores: it is not the source of live busy/retry status or session messages.

Subject: [PATCH 44/59] feat(ssh): rework remote instance setup and fix remote
 installs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adding an SSH connection now starts from the hosts in the SSH config
instead of a blank command field, ports and install options sit behind
Advanced settings, and each connection reports one of three states with
the failure text and an action that resolves it.

Remote installs no longer touch the root-owned global npm prefix: npm is
pinned to a prefix under $HOME and bun is resolved at its known location,
because an SSH login shell exposes neither on PATH. The opencode CLI is
resolved the same way and handed to the remote server through
OPENCODE_BINARY, and the server is started and stopped through the
resolved binary rather than PATH — the HTTP shutdown route sits behind UI
authentication and never stopped anything.

A managed remote server can also be published to the remote machine's own
network. That requires a UI password, enforced in the form and again in
the SSH manager.

 ## [Unreleased]
 
+- **Desktop/Remote instances:** adding an SSH connection now starts from the hosts in your SSH config instead of a blank command field. Ports, install method and passwords moved behind Advanced settings, and each connection shows Connected, Connecting, or Needs attention with the failure text and a button that resolves it.
+- Desktop/Remote instances: connecting to a remote machine now works when bun, OpenChamber or the opencode CLI live in your home directory rather than on the system path. Installing no longer fails with a permission error, and a missing opencode CLI is now reported before the connection starts instead of as a stack trace.
+- Desktop/Remote instances: a managed remote server can now also be published to the remote machine's own network, so other devices there reach it without the SSH tunnel. It requires a UI password, and stays private to the tunnel otherwise.
+- Desktop/Remote instances: disconnecting from a connection set to not keep the server running now actually stops that remote server.
 - **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.
 - **Skills catalog:** browse curated GitHub skill collections in a card-based catalog with cross-source search, skill counts, stars, recent updates, and links back to each skill's repository.
 - **Diff:** the context-panel diff can now show every change on the current branch against its base branch. OpenChamber detects the base when Git knows it, or lets you choose one once when it does not.

Subject: [PATCH 46/59] fix(providers): keep the settings provider selection
 under one owner

The selected provider on the Providers settings page shared a field with
the chat's model resolution. Changing the chat model or agent, and
`loadAgents` reconciling a selection, all wrote to it, so the page jumped
to an unrelated provider while the user was reading or editing one.

Only the sidebar click writes it now. A refresh no longer re-derives it
either: a provider missing from a refreshed list is expected while
OpenCode restarts and plugin-registered providers re-register.

Subject: [PATCH 47/59] fix(chat): yield the work status card to the context
 panel in project-less chats

The visibility hook looked the context panel up under the directory the
card reports about. A managed Chat reports about none, so the lookup ran
against an empty key and answered "closed" while the panel was open.

It now resolves the key the way the rail and the panel do, through
useEffectiveDirectory. The reporting directory is no longer an input to
this hook at all.

 - Desktop/Remote instances: connecting to a remote machine now works when bun, OpenChamber or the opencode CLI live in your home directory rather than on the system path. Installing no longer fails with a permission error, and a missing opencode CLI is now reported before the connection starts instead of as a stack trace.
 - Desktop/Remote instances: a managed remote server can now also be published to the remote machine's own network, so other devices there reach it without the SSH tunnel. It requires a UI password, and stays private to the tunnel otherwise.
 - Desktop/Remote instances: disconnecting from a connection set to not keep the server running now actually stops that remote server.
+- Chat: in a chat without a project, the work status card again steps aside when the context panel is open, instead of sitting next to it.
+- Settings/Providers: the provider you select no longer jumps to a different one on its own. Changing the chat's model or agent, and background provider refreshes, used to move the settings selection with them.
 - **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.
 - **Skills catalog:** browse curated GitHub skill collections in a card-based catalog with cross-source search, skill counts, stars, recent updates, and links back to each skill's repository.
 - **Diff:** the context-panel diff can now show every change on the current branch against its base branch. OpenChamber detects the base when Git knows it, or lets you choose one once when it does not.

Subject: [PATCH 49/59] refactor(settings): scope the settings project selector
 to settings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Picking a project in Settings called setActiveProject, which relocates
the chat, the session list, the file tree and the Git surface. Reading
another project's MCP servers or agents moved the user's whole app.

It had to, because the configuration stores resolved the directory
themselves from the active project and held one flat list. Each of them
now takes an explicit directory — omitted still means the active project,
so every caller outside Settings is unchanged — and keys loaded data by
directory next to a flat mirror of the active project. Chat, autocompletes
and pickers keep reading that mirror; a load for another directory writes
only the map. A failed load restores that directory's previous list.

Settings resolves its own directory through useSettingsDirectory, backed
by a session-local settingsProjectPath that follows the active project
until the user picks something else.

 10. Global session cache must not drive live activity indicators or message-loading state.
 
+### Configuration stores and the Settings directory
+
+`useAgentsStore`, `useCommandsStore`, `useSkillsStore`, `useMcpConfigStore` and
+the provider half of `useConfigStore` describe **one project's configuration**.
+Two surfaces read them at once: the app (chat, autocompletes, pickers), which
+wants the active project, and Settings, whose own project selector may point
+somewhere else.
+
+Each of them therefore keeps two things:
+
+- a per-directory map (`agentsByDirectory`, `commandsByDirectory`,
+  `skillsByDirectory`, `serversByDirectory`, `directoryScoped`);
+- a flat mirror (`agents`, `commands`, `skills`, `mcpServers`, `providers`) that
+  tracks the **active** project only.
+
+Every loader and mutation takes an explicit directory; omitting it means the
+active project, which is what non-Settings callers pass. A load for another
+directory writes the map and leaves the mirror alone, so browsing another
+project in Settings cannot change what chat sees. Components select through
+`selectAgentsForDirectory` / `selectCommandsForDirectory` /
+`selectSkillsForDirectory` / `selectMcpServersForDirectory` /
+`selectProvidersForDirectory`, which return stored arrays.
+
+Settings resolves its directory through `useSettingsDirectory`, backed by
+`useUIStore.settingsProjectPath`. That selection is Settings-local and not
+persisted: it follows the active project until the user picks another one. The
+Settings project selector must never call `setActiveProject` — that relocates
+the chat, the session list and the file tree.
+
+Failure is still not empty: a failed load restores that directory's previous
+list rather than clearing it.
+
 ## Selector Rules
 
 Use leaf selectors.

Subject: [PATCH 50/59] fix(settings): stop defaults from repointing a chat
 that has its own model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changing the default model, variant or agent wrote the chat's live
selection unconditionally. For a session carrying its own choice the
effect was mostly transient — ModelControls restores that choice on the
next hydration — but a message sent right after the change went out on
the new model.

The guard is the same pair of signals ModelControls restores from
(shouldPreserveManualModelOverride): a manual selection plus a saved
selection for the current session. Chats following the default still
switch immediately.

 - Desktop/Remote instances: a managed remote server can now also be published to the remote machine's own network, so other devices there reach it without the SSH tunnel. It requires a UI password, and stays private to the tunnel otherwise.
 - Desktop/Remote instances: disconnecting from a connection set to not keep the server running now actually stops that remote server.
 - Chat: in a chat without a project, the work status card again steps aside when the context panel is open, instead of sitting next to it.
+- Settings/General: changing the default model, variant or agent no longer repoints an open chat that already carries a model you picked for it. Chats following the default still switch immediately.
 - **Settings:** the project selector on Providers, Agents, MCP, Commands and Skills now only changes what those pages show. It used to switch the whole app, so opening another project's configuration moved your chat, session list and file tree with it.
 - Settings/Providers: the provider you select no longer jumps to a different one on its own. Changing the chat's model or agent, and background provider refreshes, used to move the settings selection with them.
 - **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.

Subject: [PATCH 51/59] feat(projects): pin a thinking level next to a
 project's model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A project could pin the model new chats start on, but not the level to
run it at: the default cascade dropped any variant as soon as a project
model won, and only ever considered the global one — which belongs to
the global model.

Projects now carry `defaultVariant` alongside `defaultModel`, stored and
sanitized only next to that model, and the cascade passes it through.
Both controls sit in one "Defaults for new chats" group laid out like the
Sessions defaults, and the level appears only for models that offer them.

@@ -10,6 +10,7 @@ All notable changes to this project will be documented in this file.
 - Desktop/Remote instances: disconnecting from a connection set to not keep the server running now actually stops that remote server.
 - Chat: in a chat without a project, the work status card again steps aside when the context panel is open, instead of sitting next to it.
 - Settings/General: changing the default model, variant or agent no longer repoints an open chat that already carries a model you picked for it. Chats following the default still switch immediately.
+- Settings/Projects: a project can now pin a thinking level next to its model, for models that offer levels. Both sit in one Defaults for new chats group, laid out like the Sessions defaults.
 - **Settings:** the project selector on Providers, Agents, MCP, Commands and Skills now only changes what those pages show. It used to switch the whole app, so opening another project's configuration moved your chat, session list and file tree with it.
 - Settings/Providers: the provider you select no longer jumps to a different one on its own. Changing the chat's model or agent, and background provider refreshes, used to move the settings selection with them.
 - **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.

Subject: [PATCH 52/59] test(ui): restore the two suites CI was failing on
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Neither failure came from the change that surfaced them; both suites were
asserting behavior the product had already moved.

issue-2039 mocks `session-actions`, and session creation's authoritative
steps live there: the created session becomes current under the directory
the server confirmed, and that directory enters sync's routing index. The
mock did neither, so every assertion about current session and directory
routing read an empty store. It now performs both, which is what makes
those assertions test the store's real resolution order again.

issue-2903 pinned `<ChatEmptyState />` inside ChatContainer's empty-and-idle
branch. The draft transition animation moved that surface to the draft, and
the branch now returns a neutral placeholder. What the test is actually for
— the idle branch not rendering a status row of its own — is kept.

* feat(chat): /btw command — side questions in a temporary forked session

/btw <question> forks the current session (full context inheritance) and
opens a compact peek panel docked above the composer. The composer itself
becomes the btw input while the panel is open: sends route to the fork,
the placeholder and a mode chip reflect the target, and the stop button
aborts the fork's turn. Closing the panel (or the chip's ✕) destroys the
fork, leaving the main conversation untouched.

The panel shows only the fork's own tail (messages at/after the fork
creation time) and live permission/question cards scoped to the fork.

- chat/btw/BtwPanel: peek sheet (desktop + mobile), fork-tail view,
  auto-close on disappearance, Esc to close
- lib/btw: startBtwSession (fork + rename + routed send), closeBtwPanel
  (close = destroy), filterBtwTailMessages
- ChatInput: btw-mode send routing via SendMessageOptions.sessionId,
  btw-aware activity (stop/abort), placeholder + mode chip
- useSessionActivity: exported for per-session activity reads
- i18n: btw keys across all 11 locales

* fix(chat): keep btw sends isolated

* refactor(chat): rework /btw into a metadata-scoped peek panel

- Link the active btw fork through the parent session's metadata
  (openchamber.btwSessionID) so the panel exists only in the session that
  invoked /btw, follows parent navigation, and survives reloads; the fork
  carries a kind:'btw' marker with its originalSessionID.
- Replace the wall-clock history boundary with the id of the newest cloned
  message (server-generated ascending ids), stored in fork metadata.
- Derive panel identity in useBtwPanelState; useBtwStore shrinks to
  transient per-parent UI state (collapsed/creating/destroying).
- Panel UX: dropdown-style glass surface, chat ScrollShadow, single
  title+chevron collapse toggle, muted header controls, promote action
  (keep as a full session and navigate to it), Esc collapses instead of
  destroying, reserved Working indicator row, streaming auto-follow via
  ResizeObserver keyed on content readiness.
- Add a 'peek' chat surface mode that suppresses per-message controls and
  turn footers inside the panel; user bubbles keep a small gap below.
- Hide btw forks from the sidebar, session switcher, and command palette
  until promoted; mark the fork before inserting it into local stores.
- Delete/archive lifecycle: removing the fork unlinks the parent; removing
  the parent also removes its temporary fork.
- patchSessionMetadata now mirrors updated sessions into live stores.
- Localize new strings across all 12 dictionaries; add unit tests for
  metadata helpers, the btw flow, and the UI store.

* fix(chat): clamp the btw panel below the app header when the keyboard is open

Reuse useMobileAutocompleteMaxHeight (the composer autocomplete precedent)
on the panel's scroll body, reserving the panel header and bottom spacer
height, so the sheet adapts to the visual viewport instead of riding under
the app header on mobile.

* fix(lint): drop unused destructured bindings in sessionBtwMetadata

CI eslint has no underscore ignore pattern; strip metadata keys with typed
copies and delete instead of discard-destructuring.

Subject: [PATCH 54/59] fix(chat): make the working status row swap seamlessly
 into the turn footer

The streaming status line and the finished turn footer are the same visual
line, but the swap used to jump: different font/color, a 2px left inset, a
20px row vs the footer's 32px (its h-8 action buttons set the height), and
the bottom-anchored chat pulling the line up because the finished message
carries more structure below its footer than the status row had.

Match the footer exactly: text-sm at muted-foreground/60, no left inset,
h-8 row, and mb-6 reserving the missing space below. Verified against the
live DOM: the footer appears at the exact pixel position the status row
occupied.

 - Settings/Projects: a project can now pin a thinking level next to its model, for models that offer levels. Both sit in one Defaults for new chats group, laid out like the Sessions defaults.
 - **Settings:** the project selector on Providers, Agents, MCP, Commands and Skills now only changes what those pages show. It used to switch the whole app, so opening another project's configuration moved your chat, session list and file tree with it.
 - Settings/Providers: the provider you select no longer jumps to a different one on its own. Changing the chat's model or agent, and background provider refreshes, used to move the settings selection with them.
+- **Chat: /btw side questions.** Type `/btw <question>` to ask something off-topic in a temporary session forked from the current conversation, so it inherits the full context but leaves the chat itself untouched.

 ## [Unreleased]
 
+- **Chat: /btw side questions.** Type `/btw` followed by your question to ask something off-topic in a temporary session forked from the current conversation, so it inherits the full context but leaves the chat itself untouched. The answer streams into a panel above the composer, which talks to that session while the panel is open; you can collapse it to a slim header bar, keep it as a full session, or discard it. The temporary session stays out of the sidebar and session lists until you keep it (thanks to @jaygupta17).
+- **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.
 - **Desktop/Remote instances:** adding an SSH connection now starts from the hosts in your SSH config instead of a blank command field. Ports, install method and passwords moved behind Advanced settings, and each connection shows Connected, Connecting, or Needs attention with the failure text and a button that resolves it.
 - Desktop/Remote instances: connecting to a remote machine now works when bun, OpenChamber or the opencode CLI live in your home directory rather than on the system path. Installing no longer fails with a permission error, and a missing opencode CLI is now reported before the connection starts instead of as a stack trace.
 - Desktop/Remote instances: a managed remote server can now also be published to the remote machine's own network, so other devices there reach it without the SSH tunnel. It requires a UI password, and stays private to the tunnel otherwise.
 - Desktop/Remote instances: disconnecting from a connection set to not keep the server running now actually stops that remote server.
-- Chat: in a chat without a project, the work status card again steps aside when the context panel is open, instead of sitting next to it.
-- Settings/General: changing the default model, variant or agent no longer repoints an open chat that already carries a model you picked for it. Chats following the default still switch immediately.

+- Dictation: speech is now transcribed after you stop recording. The composer shows a live waveform and timer, and long recordings split at pauses instead of cutting words.
+- Settings: the project selector on Providers, Agents, MCP, Commands and Skills now only changes what those pages show. It used to switch the whole app, so opening another project's configuration moved your chat, session list and file tree with it.

Subject: [PATCH 58/59] fix(ui): open app deep links from chat after
 confirmation (#2932)

* fix(ui): open app deep links from chat after confirmation

DOMPurify's default URI policy stripped href from anchors with custom
application schemes (obsidian://, vscode://, ...), so every app link
rendered in chat was dead across web, desktop, VS Code, and mobile.

- Classify safe app-link schemes in lib/url.ts (browser-handled,
  scriptable, webview-internal, network, and self-deep-link schemes
  stay excluded) and let openExternalUrl accept them
- Keep app-link hrefs through the markdown sanitize hook
- Intercept app-link clicks in the markdown renderer and route them
  through a confirmation dialog (Trust and open / Open once, dismiss
  to cancel) mounted in the desktop/web app root and the mobile shell
- Persist per-device trusted schemes in a zustand store; trusted
  schemes open without asking again

* feat(settings): manage trusted app link schemes in General

Add an App links section to Settings > General listing the application
schemes trusted on this device with a delete action; removing a scheme
restores the confirmation dialog for it. Register the section in
settings search.

* fix(ui): enforce app link confirmation

* fix(ui): handle app links by runtime

* fix(vscode): keep app links unsupported

* fix(settings): clarify trusted app links

 - If OpenCode restarts while a response is still running, the chat now stops with an interrupted state and a notification to continue instead of hanging silently (thanks to @sum117).
 - Usage: Z.ai credit limits now appear alongside its other quota windows.
 - Chat: file paths in messages now open from the session's workspace, even if you last browsed files in another workspace (thanks to @tomzx).
+- Chat: app links such as `spotify://` now ask for confirmation before opening another app. You can trust an app link type on one device and manage trusted links in Settings.
 - While a reply streams, the model status line under the last message now turns into the finished message's info row in place, instead of jumping when the reply completes.
 - Chat: newly sent messages and syntax-highlighted code blocks no longer briefly flicker. Bash output can also grow with its content instead of being cut off.
 - Chat: long user messages can be expanded even when their final layout finishes after they first appear.

 ## [Unreleased]
 
-- **Chat: /btw side questions.** Type `/btw` followed by your question to ask something off-topic in a temporary session forked from the current conversation, so it inherits the full context but leaves the chat itself untouched. The answer streams into a panel above the composer, which talks to that session while the panel is open; you can collapse it to a slim header bar, keep it as a full session, or discard it. The temporary session stays out of the sidebar and session lists until you keep it (thanks to @jaygupta17).

 - **Chat sessions:** start chats without choosing a project. They live in their own Chats section, rather than inheriting a project's repository and worktree context.
 - **Desktop/Remote instances:** adding an SSH connection now starts from the hosts in your SSH config instead of a blank command field. Ports, install method and passwords moved behind Advanced settings, and each connection shows Connected, Connecting, or Needs attention with the failure text and a button that resolves it.
 - Desktop/Remote instances: connecting to a remote machine now works when bun, OpenChamber or the opencode CLI live in your home directory rather than on the system path. Installing no longer fails with a permission error, and a missing opencode CLI is now reported before the connection starts instead of as a stack trace.
