feat: v0.9.5 context in tokens as well as percent

Claude's footer reads "ctx 34% 346k/1M"; the Sessions panel and the session switcher use the same label via ctxLabel(). Closes #43 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WHRLCCdXYm41Qx5kNhehaP
fix: v0.9.4 inbox badge clears when seen

@@ -38,16 +38,25 @@ The tmux server runs in its own unit, so every Claude process lives in **that**
  - The sidebar shows it with context % and a context bar; the session chip's dot shows the current session's state.
  - A "… needs you" chip jumps to other sessions that are waiting, and a desktop notification fires when one starts waiting.
  - The **🔔 inbox** lists what needs you (waiting sessions, firing Grafana alerts) and what happened while you were away (a background session finished or started waiting, CI passed or failed); its badge counts them.
+  - **Answer from the inbox:** a session waiting on a permission shows the exact command/file and **Allow / Deny** (the key is pressed only if that prompt is still on screen); other waits and finished sessions offer **Peek & reply**: the last exchange and a reply box.
 - **Matrix "Claude needs you":** when a session has waited for `DEVDESK_MATRIX_DELAY` seconds (30) and no browser tab or SSH client is attached to it, `devdesk-notify-matrix` posts one message per wait, with a link, to the hookshot webhook URL in `/etc/devdesk/matrix-webhook` (mode 600; no file = off).
 - **File & image drop:** drag files onto the terminal or paste a screenshot.
  - They're uploaded through ttyd to `/var/lib/devdesk/uploads/<session>/` (25 MB max, pruned after 7 days), and the path is pasted into Claude.
  - For images, Claude attaches them itself.
- **Ops Alerts panel:** firing and pending Grafana alert rules, each with a link to the rule.
-  - **Ask Claude** types an investigation prompt into the current session without sending it.
-  - Configure `DEVDESK_GRAFANA_URL`, plus a Viewer token in `DEVDESK_GRAFANA_TOKEN_FILE`.
+- **Ops Alerts panel:** firing and pending Grafana alert rules, each with a link to the rule and the Proxmox guest or node it's about, e.g. `→ CT 110 draupnir · monitor-02 · stopped`.
+  - **Ask Claude** starts Claude in a new session (`alert-<name>`) with the investigation already sent. The prompt has the rule, its query, summary and labels, and where it runs: the CT/VM id, the node it's on right now, and the `ssh <node> pct exec <id> --` line. Clicking it again just opens that session.
+  - Guests are matched by the alert's `instance` IP (or host name), else by name in the job or alert ("by name"). Aggregate rules with no labels (`count(up == 0)`) get a hint to run the inner query instead.
+  - **`devdesk guests [ID|IP|NAME]`** lists Proxmox CTs/VMs with the node each runs on now, status, HA state and IPs. Claude is told to use it before acting, because HA guests move. Stopped guests keep the IP they had when last seen running.
+  - Configure `DEVDESK_GRAFANA_URL`, plus a Viewer token in `DEVDESK_GRAFANA_TOKEN_FILE`. For the guest lookup, set `DEVDESK_PVE_NODES` to a few Proxmox nodes reachable by root SSH key. VM IPs need the QEMU guest agent.
 - **Repo / CI panel:** branch, ahead/behind, uncommitted changes, HEAD's Gitea CI status and open PRs for the session's folder. When CI fails, **Ask Claude to fix CI** types a prompt to read the failed job's log.
- **Files** (Ctrl+Shift+E), laid out like VS Code: an explorer tree (git colours, gitignored entries dimmed) and an editor with tabs (a click opens a preview tab, a double-click keeps it), **Go to file** (Ctrl+P in the pane), markdown previews (sanitized, with relative images), images, and a Changes view of uncommitted files with line counts, a **C** badge on files Claude edited, and diffs against HEAD. **@Claude** types `@path` into the prompt. Tabs and open folders are remembered per session. Read-only for now. Paths can't leave the session folder. The editor bundle (`/usr/share/devdesk/assets/editor.js`) loads over ttyd the first time and is cached by the browser.
- **Context:** a Claude `statusLine` command (`devdesk-statusline`) snapshots each session's model, context-window use and cost to `/var/lib/devdesk/context/<session>.json`. The Sessions panel shows it as a bar (cost in the tooltip), and Claude's own footer shows a one-line summary.

Tabs and open folders are remembered per session. Paths can't leave the session folder.
+  - **Editing:** text files are editable; ● marks unsaved tabs; Ctrl+S (or Save) writes atomically and keeps the file's mode and owner. If the file changed on disk since you opened it (Claude edited it), saving asks: Compare (a diff of disk vs yours), Overwrite or Cancel; a change on disk while you edit shows a banner instead of replacing your text. Unsaved edits are kept as drafts in the browser, so a reload or a session switch doesn't lose them. ＋ creates a file (folders as needed). The editor bundle (`/usr/share/devdesk/assets/editor.js`) loads over ttyd the first time and is cached by the browser.
+- **Paths are links:** a file path Claude prints (`web/src/files.js`, `notes.md:12`) opens in Files when clicked, at that line if given.
+- **Ops guard:** `devdesk-guard` (a PreToolUse hook) makes Claude ask before destructive commands (`pct destroy`, `zfs destroy`, Ceph pool/OSD removal, `rm -r /…`, `git push --force`, `reboot`…), even in auto mode. `DEVDESK_GUARD=0` turns it off; `/etc/devdesk/guard.local` adds rules (`regex<TAB>reason`). Bash commands are logged per session, and sessions are tagged with the hosts they touch (ssh targets, CT/VM ids).
+- **Search past conversations** (⋯ menu, palette): full text over every Claude conversation on the host; **Resume** it in a new session or **Fork** it.
+- **Plan usage:** the 5-hour and weekly windows as meters in the footer (warning at 90 %); a **PR** chip on sessions whose branch has a pull request.
+- **Quiet phone at the desk:** while a tab shows a session, Remote Control holds back phone pushes for it (client-presence marker, expires ~2 min after you leave).
+- **Context:** a Claude `statusLine` command (`devdesk-statusline`) snapshots each session's model, context-window use, plan usage and cost to `/var/lib/devdesk/context/<session>.json`. The Sessions panel shows it as a bar and Claude's own footer shows a one-line summary. On a Pro/Max plan that summary shows 5-hour plan usage; the dollar figure Claude reports there is an API-price estimate, not a bill, so it appears only for API-key billing.
 - **Light mode:** the terminal switches palettes with the page. DevDesk starts Claude with its `dark-ansi` theme so Claude draws with the terminal's 16 colours, and the light palette maps bright white to ink; tmux and the status line use ANSI colours too. A session picks up Claude's theme the next time Claude starts in it (`/exit`, then ⏎ resumes the same conversation).
 - **Phone:** a key bar replaces the shortcut hints (Esc, Tab, ⇧Tab, ^C, ↑, ↓, ⏎, Claude/Shell window), and the panels open as a drawer.
 - **SSH:** `devdesk attach <name>`, `devdesk new <name> [project]`, `devdesk rename <old> <new>`, `devdesk end <name>`, `devdesk ls`, `devdesk pick`, `devdesk repo <name>`, `devdesk alerts`.

+  * Robustness (#12):
+    - A resume that fails (an early Ctrl+C, a network error) no longer
+      replaces the session's recorded conversation with a new one: Claude
+      starts fresh only when the conversation's file is really gone;
+      otherwise the menu offers to try again.
+    - The SessionStart hook reads the session name under the registry lock
+      that rename holds, so renaming during /clear or a restart can't leave
+      the conversation id under the old name.
+    - Env files are parsed the way systemd parses them instead of being
+      sourced: values are literal (no $ expansion or command substitution),
+      and bad lines are reported and skipped.
+    - Deploys wait for the dpkg lock (120 s), log an explicit "deploy
+      FAILED" line, and the webhook answers with the result, so CI's deploy
+      job fails (and alerts) when the install fails. The deploy log is
+      rotated monthly.
+    - postinst removes the duplicate tmux terminal-features entries left by
+      upgrades before 0.3.1.
+    - Temp files of hooks killed mid-write are swept.

+    (DevDesk and code-server), by what you asked, what Claude said, the
+    commands it ran and their output (⋯ menu or the palette). Results show
+    the title, folder, dates and highlighted snippets; Resume opens the
+    conversation in a new session in its folder, Fork continues it as a new
+    conversation (claude --fork-session) and leaves the original as it is.
+    A conversation already open in a running session offers "Open" instead,
+    and resuming it twice is refused.
+  * Plan usage and PRs (#25): the 5-hour and weekly plan windows from
+    Claude's statusLine, as meters in the footer (⋯ menu on phones), with a
+    warning at 90 % of the 5-hour window; a PR chip (with review state) on
+    sessions whose branch has a pull request. (The statusLine has no prompt
+    cache expiry, so there is no cache timer.)
+  * Phone pushes held back while you're at the desk (#26): while a DevDesk
+    tab shows a session, its Claude sees a client-presence marker
+    (CLAUDE_CLIENT_PRESENCE_FILE) and Remote Control holds back pushes; the
+    marker expires about 2 minutes after the tab stops showing it. Applies to
+    sessions whose Claude started on this version (/exit, then ⏎).

+    (web/src/files.js, ./notes.md:12, /root/code/x/y.py:3) is a link when it
+    is a file of the session; it opens in Files, at that line if given.
+  * Alerts: "In a new session" (#18) opens (or reuses) alert-<name> in the
+    default folder and types the investigation prompt there once Claude is
+    up, without sending it.
+  * Ops trail and guard (#27):
+    - devdesk-guard, a PreToolUse hook for Bash, makes Claude ask before
+      commands that destroy things (pct/qm destroy, zfs/zpool destroy, Ceph
+      pool/OSD removal, rbd rm, wipefs/mkfs/dd to /dev, rm -r of / or a
+      top-level folder, git push --force, DROP TABLE, stopping devdesk-tmux,
+      reboot/poweroff…), also in auto mode. It never blocks or allows on its
+      own. DEVDESK_GUARD=0 turns it off; /etc/devdesk/guard.local adds rules
+      (regex<TAB>reason).
+    - Every Bash command is logged per session (last 500); sessions are
+      tagged with the hosts they work on (ssh targets, CT/VM ids), shown in
+      the session list, the switcher and the palette; Peek lists the last
+      commands.
+  * Sessions pick up the new hooks when Claude next starts (/exit, then ⏎).

+    - Allow / Deny (#22): a PermissionRequest hook records what Claude wants
+      to run (tool, command/file/URL, Claude's description); the inbox shows
+      it with Allow, Deny and Open. The key is pressed in that session's
+      Claude window only if the same wait is still on and the permission
+      prompt is on screen, so a stale button never types into Claude.
+    - Peek & reply (#23): the last thing you asked and Claude's latest answer
+      (from the session's transcript), and a reply box; the reply is pasted
+      as one bracketed paste and sent. Available for sessions that wait for
+      input and from "finished" entries.
+    - Matrix "needs you" messages include the command.

+  * Edit and save files in the Files pane (#20):
+    - Text files open editable; ● marks unsaved tabs; Ctrl+S or Save writes
+      through `devdesk attach --fs-write`: a temp file in the same folder,
+      mode and owner kept, swapped in with mv.
+    - Conflict detection: the save carries the sha256 of the version you
+      opened; if Claude (or anyone) changed the file since, nothing is written
+      and you choose Compare (diff of disk vs yours), Overwrite or Cancel.
+    - A file that changes on disk while you edit it shows a banner (Compare,
+      Reload, Keep mine) instead of replacing your text; clean files still
+      reload in place.
+    - Unsaved edits are mirrored to the browser as drafts (flushed when the
+      page closes), so a reload, a crash or a session switch doesn't lose
+      them; a draft for a file that changed since offers Compare/Restore/
+      Discard.
+    - Closing a tab with unsaved changes asks Save / Don't save / Cancel;
+      leaving the page warns.
+    - ＋ New file (missing folders are created; never outside the session
+      folder, and never through a symlink out of it).
+    - Markdown previews show unsaved Source edits. Latin-1 files stay
+      read-only.

jaredandClaude Opus 5.5	c0f475bffe	feat: v0.9.2 Ask Claude on an alert starts an investigation session build-deb / Lint, test, package (push) Successful in 2m23s Details build-deb / Deploy to CT 126 (push) Successful in 30s Details build-deb / Notify on failure (push) Skipped Details - Ops Alerts → Ask Claude now calls `devdesk attach --investigate SESSION UID`. The server looks the alert up, writes the prompt and starts Claude in a new alert-<name> session with it as the first prompt, already sent. Prompts are stored in prompts/<session>.txt and consumed once by devdesk-claude-run. A session that is already running is just opened. - The prompt has the rule, query, summary, details and labels, and where it runs: the CT/VM id, the node it is on now, status and HA state, and `ssh <node> pct exec <id> --`. It reminds Claude that HA guests move (`devdesk guests <id>`), and gives aggregate rules a hint. - `devdesk guests`: Proxmox inventory over SSH (DEVDESK_PVE_NODES). pvesh gives the cluster view; each node gives lxc-info and guest-agent IPs. Cached in guests.json, keeping last-seen IPs for stopped guests; --alerts refreshes it in the background every 5 minutes. - Alerts carry uid, query, description and targets, matched by instance IP/host or by name; each card shows the target. - cmd_alerts moves to libexec/devdesk-ops.sh.

jaredandClaude Opus 5.5	74927a7640	fix: v0.9.1 robustness cleanups build-deb / Lint, test, package (push) Successful in 3m53s Details build-deb / Deploy to CT 126 (push) Successful in 10s Details build-deb / Notify on failure (push) Skipped Details - run_resume falls back to a new conversation only when the transcript file is gone; other failures end at the menu with the recorded id intact. - The SessionStart hook resolves the session name under the registry lock; rename holds it across tmux rename-session and the registry move (dd_registry_locked, nestable). - dd_load_env parses KEY=value like systemd instead of sourcing the files. - devdesk-deploy: DPkg::Lock::Timeout, explicit FAILED lines on stdout and in the log; the hook answers synchronously and CI checks the HTTP status. logrotate for the deploy log. - postinst drops duplicate terminal-features entries; hooks sweep stale temp files.
