-Config backups: timestamped snapshots of the files that hold your customization (settings, CLI overrides, custom endpoints, webhook, linked cases and, in multi-user mode, accounts), taken at startup and whenever one changes. On by default into `~/.codeman/backups/config`; the folder and the retention (keep N backups, drop older than N days) are configurable in Settings → System, with Back up now and Restore. Retention only deletes folders Codeman made, never the newest backup. A comparison view shows what changed between two backups, or between a backup and the running config, without ever showing a credential's value.

-The plan-usage chip in the header gains a `Copilot` row: the calendar-month premium-request quota, with the request counts and the reset in the tooltip. The host reads it every 10 minutes from GitHub's `copilot_internal/user` endpoint with the Copilot CLI's own sign-in token. It is on by default while the CLI is installed and signed in (an absent Plan Usage Limits setting reads as on), and turning Plan Usage Limits off in App Settings stops the request. Any failure leaves the chip without a Copilot row. The FAQ, Installation and Security pages say so.

-The File Viewer window can be resized and expanded, and jumping between files now has Back and Forward. Drag the corner grip to resize it, or use the Expand button to fill the screen (remembered across opens). Following a link from one document to another adds it to a list that the ← and → buttons, or Alt+← and Alt+→, walk through; opening something new from the middle of the list drops the forward entries, and closing the viewer clears it. Leaving unsaved edits still asks first.

-The cap of 50 concurrent sessions can now be set with `CODEMAN_MAX_SESSIONS` (1 to 462, read at startup; a larger value is clamped to 462), for a machine with the memory for more sessions or a small one that should run fewer. Without it nothing changes. A value that is not a positive integer falls back to 50, so a typo never blocks session creation. In multi-user mode the per-user cap still defaults to half the global cap, so it follows the new value unless `CODEMAN_MAX_SESSIONS_PER_USER` is set.

-A multi-line prompt sent through the mux (`POST /api/sessions/:id/input` with `useMux`) now keeps its line breaks. `sendInput` used to strip every `\n` before the text reached tmux, so `"line one\nline two\r"` arrived as `line oneline two`. The lines now go in as one bracketed paste, the same paste a single-line prompt already uses, and the Enter after it submits them together; multi-line text without an Enter is pasted too instead of typed. A shell runs each line. The submit check that re-presses a stranded Enter does not yet recognise a multi-line paste in the composer, so the unattended senders stay single-line: cron still rejects multi-line prompts, respawn's update and kickstart prompts and the auto-compact focus prompt now have their lines joined with a space (they used to run together), `codeman agent send` and the TUI keep refusing or joining multi-line input, and the agent skill's `sendwait` now joins the lines of a multi-line prompt with a space too.

-A custom llama.cpp model whose parallel slots share a context pool too small for concurrent Claude Code requests now gets an in-app warning. Four simultaneous 40K-token requests against a 4-slot ~131K pool all failed with "Context size has been exceeded" while the old total-context check stayed silent. Discovery records each model's slot count (from `--parallel`/`-np`, or `/props` `total_slots` when the launch command states none) and the warning names the fix: `--parallel 1`, or a context large enough for every slot.

 # aicodeman

+
+### Minor Changes
+
+- ### Thanks
+  - @opticon454 for five PRs: config backups you can compare and restore (#661, ten review rounds), a File Viewer you can resize, expand and walk Back and Forward through (#659), GitHub Copilot's premium-request quota in the plan-usage chip (#662), a warning when llama.cpp's parallel slots leave too little context per request (#658, from #641), and a bare `npx vitest` that can no longer write into your real `~/.codeman` (#660, from #640).
+  - @JDProfresh for four PRs: the opt-in prompt-cache keep-alive (#666, step 2 of #554), Markdown links to file paths that open in the File Viewer (#665), a phone keyboard that stays up while you press accessory keys (#673), and a session swipe that no longer taps or scrolls the session you are leaving (#674), with the iPhone testing behind both phone fixes.
+  - @christianhaberl for four PRs: `CODEMAN_MAX_SESSIONS` (#668), tmux prefix keys that can no longer move a browser tab onto another session (#669), multi-line prompts that keep their line breaks (#670), and rediscovered tmux sessions that keep their own folder (#667). Also for the earlier #224, #225, #226 and the session sidebar (#307), whose commits carried an agent identity that GitHub credits to another account.
+  - @johoja12, a first-time contributor, for scroll batches that stay with the tab that made them, smoother trackpad scrolling and wheel scrolling in fullscreen Codex (#645), measured against the real CLI through five review rounds.
+  - @ludovicfourrage for touch scrolling in apps that track the mouse themselves (#664), and the careful write-up in #663.
+  - @aakhter for a default tab group per case (#676).
+
+  **Config backups (#661).** Codeman now keeps timestamped copies of the files that hold your setup: settings, CLI overrides, custom model endpoints, the webhook, linked cases and, in multi-user mode, the accounts. It takes one at startup and whenever one of them changes, into `~/.codeman/backups/config` by default. App Settings → System lets you pick the folder and the retention (keep N backups, drop ones older than N days), back up now, compare two backups or a backup with what is running (credentials are never shown, only whether they changed), and restore one. A restore first saves what it is about to replace, so it can be undone, and retention only ever deletes folders Codeman made and never the newest backup.
+
+  **Keep an idle Claude session's prompt cache warm (#666, opt-in).** Claude Code's prompt cache expires after an hour of quiet, and the next prompt then pays to re-read the whole conversation. Switch on **Keep the cache warm while idle** in a session's Respawn tab (or **Keep prompt caches warm** in App Settings → System → Automation for every new session) and Codeman sends a one-line keep-alive turn about five minutes before the cache would expire. It only does that when nothing else is going on: an empty prompt, no open dialog, nobody typing, no respawn, Ralph loop or waiting agent, no usage-limit pause. It stops on its own a while after your last prompt (**Keep warm for at most**, default 2 hours). A session started with it on also launches with Claude Code's own idle compaction off (Claude Code 2.1.290 or newer). The keep-alive raises no alert, push, webhook or Away-digest row, and the readout's Status line says what it is doing.
+
+  **A default tab group per case (#676).** Case settings has a **Default session group**: every new session for that case lands straight in that tab group, in the same write that creates it, so it never flashes in Ungrouped first. An explicit group on the create request and a spawned child following its parent still win. It is stored per user and survives a group rename.
+
+  **A File Viewer you can resize, with Back and Forward (#659).** Drag the corner grip to resize the window, or press Expand to fill the screen (remembered on this device). Following a link from one file to another builds a history that the ← and → buttons and Alt+← / Alt+→ walk through. Phones keep the full-screen viewer.
+
+  **Copilot's premium-request quota in the plan-usage chip (#662).** With the GitHub Copilot CLI installed and signed in, the header chip gains a Copilot row for the month's premium requests, with the counts and the reset date in the tooltip. Codeman reads it every 10 minutes from GitHub with the Copilot CLI's own sign-in token. It is on by default, like the Codex row, and turning Plan Usage Limits off in App Settings stops the request.
+
+  **More (or fewer) sessions with `CODEMAN_MAX_SESSIONS` (#668).** The cap of 50 concurrent sessions can be set at startup, from 1 to 462. A value that is not a positive integer falls back to 50, and the per-user cap in multi-user mode follows it unless `CODEMAN_MAX_SESSIONS_PER_USER` is set.
+
+  **Multi-line prompts keep their line breaks (#670).** A prompt sent through the API with `useMux` used to arrive as one welded line (`line oneline two`). Its lines now go into the pane as one bracketed paste, followed by the Enter that submits them together. The senders that run unattended (cron, respawn's update and kickstart prompts, the auto-compact focus, `codeman agent send`, the TUI and the skill's `sendwait`) stay single-line and join lines with a space, because the submit check cannot yet recognise a multi-line paste in the composer.
+
+  **A warning for llama.cpp slots that split the context too thin (#658).** A custom llama.cpp model that runs several parallel slots splits its context between them, and four 40K-token Claude requests against a 4-slot, 131K pool all failed with "Context size has been exceeded". Discovery now records each model's slot count, and a Claude launch warns when one slot gets less than 40K tokens, naming the fix (`--parallel 1`, or a context large enough for every slot).
+
+  **Fixes.**
+  - **tmux prefix keys stay out of browser tabs (#669).** Ctrl+B then `)`, `(`, `s` or `w` in a tab switched its tmux client to another session while the tab kept the first one's name. Codeman's tmux socket now keeps only Ctrl+B Ctrl+B (send-prefix) in its prefix table, set at session start and at boot. This also means `Ctrl+B d` no longer detaches a terminal attached to that socket: `codeman tui` and `scripts/tmux-manager.sh` detach with F1.
+  - **Scrolling stays with its tab, and fullscreen Codex scrolls (#645).** A queued wheel batch can no longer land in a tab you switched to, trackpads keep their fractional travel instead of dropping it, the first wheel report of a tab visit goes out at once, and Codex gets wheel reports while it has mouse tracking on (measured on Codex 0.163.0, where an approval prompt's selection is unaffected).
+  - **Touch scrolling in apps that track the mouse (#664).** A finger drag and its fling now scroll a program in the pane that asked for SGR mouse reports (a TUI in a shell tab, for example) instead of scrolling a local buffer that cannot show it. Other mouse encodings are left alone.
+  - **A session swipe only switches sessions (#674).** A sideways swipe on the terminal no longer also opens a link, taps a CLI menu or toggles the keyboard on the session you are leaving. A deliberate swipe gets 500 ms instead of 300, a selection or a second finger pauses it, and a scroll that starts on a sideways thumb arc still scrolls.
+  - **The phone keyboard stays up (#673).** Arrow, Tab, Esc and the other accessory keys that act on the terminal no longer blur it for a moment, so the toolbar stops bouncing on every tap.
+  - **Markdown links to files open in the File Viewer (#665).** A link like Codex's `[label](/abs/path.json)` in the response viewer now opens the file instead of a same-origin 404 tab, and its label keeps the prose font.
+  - **Rediscovered sessions keep their folder (#667).** A tmux session Codeman finds again on its socket (after `mux-sessions.json` was lost) now gets the directory tmux reports for its pane instead of the server's own, so a respawn goes back to the right project.
+  - **Web tabs send POST bodies to dashboards that read Content-Length.** Codeman's web-tab proxy now relays the browser's Content-Length, so a dashboard built on Python's `http.server` or a small Go or C server no longer sees an empty body on every POST made through a web tab.
+
+  **Fixes applied while landing.** A restore that fails partway now says which files it restored, which it could not and where the pre-restore copy is, re-reads what was written and refills the Settings form; backup passes list the manifests once, and a pre-restore copy equal to the newest backup is not made twice (#661). A failed keep-alive write is retried before the expiry instead of never, an unreadable `settings.json` is logged once instead of every minute for every session, the keep-alive's own hooks stay out of the run summary, and saving App Settings re-plans keep-alives only when their settings changed (#666). The Copilot quota read checks the setting and the sign-in token before it ever probes for the CLI, so a machine without Copilot runs no login shell every 10 minutes, and drops a header the Copilot CLI itself does not send (#662). The prefix-table reset still binds send-prefix on an empty table and no longer reruns on every session for a prefix tmux lists escaped (#669). Claude worktree sessions follow the case's default group like every other CLI's (#676). The remote-history PATH change that rode along in #645 was left for its own PR. Smaller touches: the Expand button keeps its label while pressed and Alt+← / Alt+→ are listed in the shortcut overlay and help (#659); the scroll log names xterm's mouse encoding (#664); the response-viewer link test covers `?query` and folder links (#665).
+
+  **Docs and tests.** A bare `npx vitest run` from the repo now uses the isolated CI config instead of running without the setup file, the helpers that delete test folders refuse to run outside a sandboxed HOME, and the temp-HOME teardown is bounded so a stuck writer cannot time the hook out (#660). New sections and lines for config backups, the keep-alive and the Copilot quota in the architecture notes and `CLAUDE.md`, a test that a deleted pane directory is never adopted (#667), the codeman skill preamble re-stamped 1.44.0, and browser tests for the touch-scroll and swipe fixes.
+
