fix(cli): a running server notices a CLI the installer just added

A running Codeman remembers a missing CLI for up to 5 minutes, so a status
poll never spawns a login shell, and its Run button reads that same memory.
So "Run fails, add the agent, Run again" kept saying the CLI was not
installed, right after the app had said it was ready.

install.sh now touches `cli-installed` in the data dir once a CLI has landed,
and resolve() leaves the backoff when that file's mtime changes. It is one
stat, inside the backoff branch, and buys one run of the chain, so a resolved
CLI never pays for it and a CLI that is still missing goes back to waiting.
Re-walking PATH during the backoff would have found hand installs too, but it
would put a synchronous stat of every PATH entry on the request path, where
one dead network mount freezes the server (#516), and execute candidates that
were already refused.

Binding non-loopback (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` starts anyway but prints a loud warning; `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` acknowledges it. ⚠️ The production systemd unit passes no `--host`, so prod binds **localhost only**: reach it via `tailscale serve`/tunnel to `127.0.0.1`. A loopback bind is reachable through a same-host tunnel but NOT by a browser hitting the box's LAN IP. `install.sh` is separate and prompts for the binding (defaulting to LAN + a password), and preserves the existing binding on re-runs. → [architecture-invariants#default-bind-and-the-non-loopback-warning-path](docs/architecture-invariants.md#default-bind-and-the-non-loopback-warning-path), `docs/security-architecture.md`
 - **Instance isolation / multi-instance attach danger** — the data dir (`~/.codeman`) and tmux socket (`tmux -L codeman`) are PROCESS-WIDE and shared by every Codeman on the machine, derived from `CODEMAN_INSTANCE` via `src/config/instance.ts`. ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions**, resizing and mutating them. `$HOME` isolation is NOT enough because tmux is system-global. To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes dir + socket together), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually; `scripts/run-beta.sh` does this for a beta alongside prod. **Any new `~/.codeman/...` path MUST go through `dataPath()`**, never `join(homedir(), '.codeman', …)`, and **any new `tmux -L` caller through `resolveTmuxSocketName()`** (both in `config/instance.ts`): the TUI shells out to tmux from a second process, and a hardcoded `codeman` there would point a beta instance at prod's panes. → [architecture-invariants#instance-isolation-and-the-multi-instance-attach-danger](docs/architecture-invariants.md#instance-isolation-and-the-multi-instance-attach-danger)
 - **The prefix table on Codeman's socket holds only `<prefix> send-prefix`** — browser tabs are tmux attach clients, and tmux's stock bindings let Ctrl+B `)`/`s` move a tab onto another session. `createSession` resets the table, and `reconcileSessions()` at boot for sessions that survived an upgrade (`src/tmux-prefix-table.ts`); `root` and `C-<letter> detach-client` (the TUI attach's way out) are left alone, so F1 and that alias reach browser tabs for the length of an attach. Alt+1..9 are `if-shell` bindings that `switch-client` only for the TUI's own client (`client_tty` plus a one-shot pid hook), so a browser tab's Esc-then-digit does not move it. Docker and owned-remote nested servers get the same reduction (`C-q send-prefix` only) in their create chain. ⚠️ So `Ctrl+B d` does not exist there: anything attaching a user's terminal claims its own detach key (F1 in `root`, as `codeman tui` and `scripts/tmux-manager.sh` do). → [architecture-invariants#the-prefix-table-on-codemans-socket-holds-only-send-prefix](docs/architecture-invariants.md#the-prefix-table-on-codemans-socket-holds-only-send-prefix)

 - **User-chosen paths are probed BOUNDED, never with `existsSync`/`statSync`** (#516): a linked case or a `workingDir` can sit on a network mount that stopped answering. A synchronous check there freezes the whole server, and an unbounded async `stat`/`lstat`/`readFile` holds one of libuv's threadpool workers (4 by default, shared with every `fs`, `dns.lookup` and `crypto` call) until the mount returns. On a request or spawn path use `probePath()`/`probePathKind()` (`utils/bounded-path-probe.ts`, read its `@fileoverview`). ⚠️ `unknown` is NEVER `absent`: nothing is created, scaffolded or 404'd on it. Bulk scans keep the stall cap; a request for ONE path the user named may pass `{ pastCap: true }`, which still stops at the ceiling that keeps one worker free; and a helper that would otherwise touch the path skips whatever is still `unknown`. User-facing errors for it go through `describeUnknownPath()`, so a refused probe is not reported as a broken folder.
 - **Headless screenshots: `deviceScaleFactor` MUST be 1, and write unique filenames** — under DSF=2 xterm's WebGL renderer draws glyphs at ~2× nominal size while still *reporting* nominal cell dims, so only the pixels reveal it and only the terminal font looks wrong. And overwriting a fixed output path leaves OS image viewers showing the old render, which reads as "the fix didn't work"; `scripts/capture-real-overview.mjs` mints a timestamped filename per run. Seed the per-device `localStorage` keys (`codeman:skin`, `codeman-font-size`, `codeman-app-settings`) so the capture matches a real device. → [architecture-invariants#headless-screenshot-capture](docs/architecture-invariants.md#headless-screenshot-capture)

Wheel and touch forward only with observed `cliMouseTracking`: **Claude ≥ 2.1.187, tracked Codex, or tracked Copilot**.

Inline/untracked Codex retains local history or the capability-gated paging fallback. Copilot has no version gate; a stale/false tracking flag falls back to PageUp/PageDown. Touch alone has one more branch (`_shouldForwardTouchToApp`): in any mode, a drag also forwards as SGR wheel reports while xterm ITSELF tracks the mouse with SGR encoding (an app in the pane asked for it; a tracking mode other than `x10` and `coreMouseService.activeEncoding === 'SGR'`, so DEFAULT, X10 and SGR-pixel apps fail closed), because xterm encodes a wheel there but the touch listeners consume the drag. ⚠️ `getClaudeCliVersion()` must never cache a FAILED probe. ⚠️ Hand-report clicks only while the CLI has mouse tracking on: `_shouldReportMouseToCli()` gates all three report sites on `cliMouseTracking` (from `_recordStrippedMouseMode()`, session.ts), or a plain shell prints the reports as literal text. ⚠️ A `TerminalTile` (grid tile, split Pane B) forwards the wheel as SGR reports, pages it and reports clicks through these SAME gates with itself as the target (its terminal, its session, never `activeSessionId`), and scrolls Shift+wheel itself (xterm makes it a horizontal no-op); never copy the mode lists into terminal-tile.js. ⚠️ The hollow-buffer PageUp/PageDown fallback (`_maybePageCliTranscript`) stands down when the last capture reported tmux scrollback (`paneHistoryLines` > 0: a tail replayed after a server restart carries only the attach repaint), so the gesture scrolls locally and the scroll-to-top pull loads `full=1`; 0 and unknown keep paging.

Unit/label names live only in `config/service-names.ts`. `service install` bakes the installing shell's PATH into the unit and never writes `CODEMAN_PASSWORD` into it. → [architecture-invariants#detached-start-and-service-install](docs/architecture-invariants.md#detached-start-and-service-install)

 - **How it's reachable, your choice.** **Tailscale** (loopback bind fronted by `tailscale serve`, so you get `https://<machine>.<tailnet>.ts.net` with a real certificate and your tailnet as the login, no password needed), **any device on your network** (`0.0.0.0`, with a strongly recommended password prompt), or **this machine only** (`127.0.0.1`, safest). Skipping the password on a network bind requires an explicit confirmation and ends with a loud warning. The highlighted default reflects what is already on the machine (Tailscale when it is already connected, your existing binding on a re-run), and a bare Enter never pulls in new software. If another app already owns `:443` on your node, Codeman goes under `https://<machine>.<tailnet>.ts.net/codeman` or on a second port instead of replacing it. A bare `codeman web` started by hand still defaults to loopback.
 - **The name is yours to choose.** By default the URL uses the machine's existing tailnet name. Answering yes to the second question renames the machine to `codeman-<hostname>` (which also renames it for SSH, so the default is no); `install.sh name` does it later.
 - **Re-run to update.** The same one-liner updates a finished install in place: local changes in `~/.codeman/app` are stashed (never discarded), and a running service is restarted and verified. If a first install was interrupted, re-running resumes the full setup instead. `install.sh status` prints the URLs and the QR code again; `install.sh update`, `install.sh tailscale` and `install.sh uninstall` also exist.
+- **No administrator rights needed.** On an account without `sudo` (or a Mac account that is not an administrator), the installer downloads Node.js from nodejs.org and the tmux project's own build into `~/.codeman/runtime`, each checked against its SHA-256, and takes the source as an archive when there is no working git. `--no-admin` forces that route. Two limits: Linux needs make, a C++ compiler and python3 to be there already, and the tmux download needs macOS 15 or newer. Details in the [wiki](https://github.com/Ark0N/Codeman/wiki/Installation#without-administrator-rights).
 - **Flags for the impatient.** `curl -fsSL https://getcodeman.com/install | bash -s -- --tailscale --service` answers the questions from the command line (`--lan`, `--local`, `--run`, `--no-start`, `--name <n>`, `--port <n>`, `--yes` too). **CI / headless:** without a terminal attached, steps that would change your system abort with instructions instead of running silently; set `CODEMAN_NONINTERACTIVE=1` to approve them for automation.

 ⚠️ It executes ONLY commands from the embedded block (`CLI_INSTALL_CMD_TRUSTED`) — there is no network fetch of the catalogue at install time to worry about at all.
 
+**No-admin route** (`--no-admin` / `CODEMAN_NO_ADMIN`, 2026-11-05). Everything Codeman writes was always under `$HOME`; administrator rights were only ever spent on prerequisites. `resolve_admin_mode` decides once per run whether those rights may be asked for: root yes; a Mac account outside the `admin` group no (unless a Homebrew it can write to exists); on Linux no without a `sudo` binary, or when the account is outside `sudo`/`wheel`/`admin` AND `sudo -n true` fails. ⚠️ It is never decided by `sudo -v`: that prompts, and a refused password from an account outside sudoers is reported to the administrator. A refused password on the system route offers this route instead of ending the run (`sudo_session_try`).
+
+On this route Node.js comes from nodejs.org (`latest-v<major>.x/SHASUMS256.txt` names the tarball AND carries its checksum, one fetch, no JSON parsing) into `~/.codeman/runtime/node`, and tmux from the tmux project's `tmux-builds` release into `~/.codeman/runtime/bin`. ⚠️ `tmux-builds` publishes no checksum file, so `tmux_build_sha256` pins all four digests of `TMUX_BUILD_VERSION`; bump the version and the digests together (the GitHub release API returns them as `digest`). ⚠️ A download is verified BEFORE it is unpacked or run, and an empty expected digest never passes. `node`, `npm`, `npx` and `tmux` are linked from `~/.local/bin` (`link_into_local_bin` refuses to replace a file that does not already point into the runtime, and uninstall removes only such links): the `codeman` launcher is `#!/usr/bin/env node`, and a non-interactive shell never reads the PATH line written to an interactive profile. The runtime's `node/bin` also goes on PATH and on the LaunchAgent's `svc_path`, since `npm install -g` puts AI CLIs beside that Node.js.
+
+⚠️ `no_admin_blocker` runs before the first download and stops for what this route cannot supply: a C/C++ toolchain on Linux (node-pty 1.1.0 compiles there; a node-pty with Linux prebuilds is what would lift this, and it is a dependency decision, not an installer one), musl, a platform nodejs.org or tmux-builds has no build for, and macOS below 15 (the tmux build's deployment target). ⚠️ Nothing between the "No-admin route" header and "End of the no-admin route" may run `sudo`, `ensure_sudo`, `run_as_root`, Homebrew or `xcode-select --install`; `run_as_root` itself refuses while `NO_ADMIN=1`, so a missed call site fails instead of prompting.
+
+**Driving the installer from a program** (`--ai-cli`, `--progress`, `install.sh preflight`, 2026-11-06). Codeman Desktop installs with no terminal: it runs `install.sh --no-admin --service --progress --ai-cli <id>|none` with `CODEMAN_NONINTERACTIVE=1` and its stdin closed, and asks the two questions in its own window (`packages/desktop/src/gui_install.rs`). `--ai-cli` answers the agent menu, so the one thing `CODEMAN_NONINTERACTIVE` used to decide by itself (the first entry of the catalogue) is the user's. ⚠️ `cli_offerable` is the ONE rule for what can be installed here: the menu, `--ai-cli` and `preflight`'s `installable` all read it, so the app's list and the menu cannot disagree. A name that is not offerable here warns and carries on, and never falls back to another CLI; a typo dies in `parse_flags` before anything runs. `install.sh agent <id>` installs one CLI and nothing else, for Codeman Desktop's *Add a coding agent*: no service, no source, no build, so it may run next to a live server, and an agent already there is a success that runs nothing. ⚠️ It calls `run_offered_cli`, checks `CLI_FOUND_PATH` of that one entry itself and only then prints `done`: `install_offered_cli`'s gate is fatal only when NO CLI is left, which is right for a first install and would report success here, where another CLI is usually present. ⚠️ The app passes `--no-admin` to both `preflight` and `agent`, because that flag decides what `cli_offerable` allows; pinned in `gui_install.rs`. ⚠️ The app runs it from a folder of its own (`Run::Agent`), so `ps` never reads an agent run as "Codeman is being installed". A running server remembers a missing CLI for up to 5 minutes (`cliResolveRetryDelayMs`), and Run reads that memory, so `mark_cli_installed` touches `cli-installed` in the data dir and `resolve()` leaves the backoff when that file's mtime changes. ⚠️ That check is one `stat` inside the backoff branch and buys one run of the chain. Never replace it with a re-walk of PATH during the backoff: that puts a synchronous stat of every PATH entry on the request path (#516) and executes candidates already refused. The app never restarts the service for this. Only `install.sh` writes the marker, always under `~/.codeman`, so a CLI installed by hand, or another `CODEMAN_INSTANCE`, waits out the backoff as before, and so does a server older than this. ⚠️ `preflight` prints only JSON on stdout and changes nothing; `schema` moves only when a field changes meaning, because the app ships on its own and refuses a number it does not know. Fields may be added freely. ⚠️ `progress_phase` writes to stderr, not stdout, because a function can run inside a `$( )` that captures stdout. The phases must stay in the order of `PHASES` in `connect.html` (pinned by test), `done` must stay the last thing `main()` reports, since a run that ends without it failed, and an unknown phase is ignored by the app, so a new phase needs no new app. ⚠️ `error()` carries the text as `@@codeman error`, and the app shows the FIRST one: the ones after it are consequences (`Installation failed. Partial...`).
+
+⚠️ **git is judged by whether it works, never by `command -v`.** On a Mac without the Xcode Command Line Tools `/usr/bin/git` is a stub that opens Apple's install dialog, so `check_git` judges that path by `xcode-select -p` and never executes it; any other git is asked for `--version`. `scripts/git-hooks.mjs` has the matching guard (no `.git`, no `git` call), because postinstall runs it on every `npm install`. Without a working git the source is an archive (`fetch_source_archive`, GitHub's `archive/<ref>.tar.gz` or `CODEMAN_TARBALL_URL`) and the install directory carries the marker `.install-source`, which `detectInstallKind` reads as `archive` (the name is pinned across both files by `test/install-sh-invariants.test.ts`). ⚠️ An archive install is replaced as a WHOLE, never patched in place: nothing says which files a newer version dropped, and a stale `src/*.ts` would be compiled. The new tree is fetched and built in `<install dir>.new` and `finish_source_swap` moves it into place only after `npm run build` succeeded, so a failed update leaves the running install untouched; a re-run on a machine that has gained a working git stages a clone instead, which turns the install back into a git one. ⚠️ `download`/`download_to_stdout` resolve `DOWNLOADER` themselves (`require_downloader`): only `main()` used to set it, so a subcommand that downloads died on `set -u` with the message swallowed by the step log.

+`CODEMAN_NO_ADMIN=0` switches the detection off. Nothing on this route runs `sudo`,
+Homebrew or the Xcode tools installer.
+
+What to know about it:
+
+- **Linux needs make, a C++ compiler and python3 to be there already.** node-pty compiles
+  from source on Linux, and a compiler is a system package. The installer checks this
+  before it downloads anything and names what is missing. macOS needs no compiler.
+- **The tmux download needs macOS 15 or newer** (and x86_64 or arm64 on either system).
+  On an older Mac an administrator has to install tmux once (`brew install tmux`); the
+  rest then works without one.
+- **An install without git updates by re-running the install line**, not from App
+  Settings. The re-run builds the new version beside the old one and swaps it in only
+  after the build succeeded, so a failed download or build leaves the install as it was.
+  Once the machine has a working git, the next re-run turns the install into a normal
+  clone and in-app updates work again. On a Mac, "a working git" means the Xcode Command
+  Line Tools are installed: without them `/usr/bin/git` only opens Apple's install dialog,
+  and the installer never runs it.
+- **Tailscale works where it is already installed and your account may configure it.** On
+  Linux, installing it, logging in and granting serve rights each need an administrator
+  (`sudo tailscale set --operator=$USER`, once). Local network and this-machine access
+  need nothing, and `install.sh cloudflared` puts `cloudflared` in `~/.local/bin`.
+- `node`, `npm`, `npx` and `tmux` are linked from `~/.local/bin`, and
+  `~/.codeman/runtime/node/bin` is added to your PATH, so a CLI installed with
+  `npm install -g` is found as well.

When nothing answers there but one of your own Codeman servers runs (found with `ps` and `lsof`: a `codeman web --port 4000` in a terminal, say), the tab opens that one, or says where it listens; it never offers to start a second server, which would take over the first one's sessions, and Start refuses while one runs. Start asks launchd to run the LaunchAgent (`kickstart`, or `bootstrap` when it is not loaded), so the server keeps its own settings and supervision; without a LaunchAgent it runs `codeman web -d`. The login comes from where Codeman keeps it: the LaunchAgent's `CODEMAN_USERNAME`/`CODEMAN_PASSWORD`, else `~/.codeman/.env` (what Codeman's command-line clients read), `admin` by default. It goes only to `127.0.0.1` on that Codeman's port, only while one of your own Codeman processes holds that port, is never saved to the Keychain, and never reaches the page. Whether Codeman is installed is looked up in its files and processes, then the login shell; the interactive profile (nvm in `.zshrc`, say) only on *Check again*.

Port 3000 is used unless something else answers there, then the next free one. While the installer runs, the app looks every 3 seconds and opens Codeman as soon as it answers; it stops looking after the first answer, after 30 minutes, or 90 seconds after a finished install whose server never answered (then it offers Start).

Whether Codeman is installed is looked up in its files and processes, then the login shell; the interactive profile (nvm in `.zshrc`, say) only on *Check again*. Install sets Codeman up from the app itself, with no Terminal and no password (see Decisions). It fetches the installer, asks it what is on this Mac, then asks two things: which coding agent to install, only when this Mac has none (the list comes from the installer, and *Skip for now* is there), and who can reach Codeman (this Mac only, or the local network with a password). A checklist follows the install, the installer's output is one click away, and Cancel stops it; installing again picks up where it stopped. Codeman runs as a LaunchAgent, so it keeps running when the app quits and starts at login. Port 3000 is used unless something else answers there, then the next free one. Closing the app does not stop an install: it runs on its own, and the app picks it up when it opens again. When it is done the app looks every 3 seconds and opens Codeman as soon as it answers; it stops looking after the first answer, after 30 minutes, or 90 seconds after a finished install whose server never answered (then it offers Start). *Install in Terminal instead* runs the installer in a Terminal window, for what the app cannot do (see Known limits): it may ask for the Mac password (Homebrew) and asks its own questions there. The app offers it by itself on a Mac where the graphical install cannot finish. An install still running in Terminal is recognized by its process, so the tab waits for it instead of offering Install twice. *Add a coding agent*, on this tab and in the app menu whenever Codeman is on this Mac, is the same chooser after the install: pick one agent, watch it install, open Codeman. It needs no password, leaves a running Codeman alone, and can be cancelled or left running like an install. After *Skip for now* the app says Codeman has no agent yet and offers this before it opens Codeman. |
 | **Another machine** | The second tab connects to a server by address (below). *Codeman is not installed there yet?* opens Terminal, connects with `ssh -t` and runs Codeman's installer on that machine, which asks its questions there; the app then suggests `http://<host>:3000` and the installer prints the real address at the end. The SSH login is checked to the characters of a user and host name (no option can be slipped in) and may carry a `:port`. The remote command runs under `bash -o pipefail`, so a failed download fails the install instead of reporting success. The same tab shows the one-line install command, with a Copy button, to run on a machine by hand. |
 | **Connect screen** | Server address, recent servers, a login for password-protected servers (password kept in the macOS Keychain), auto-connect at launch. It explains each failure: nothing listening; wrong password; too many failed logins (the password field stays open, since a single-user Codeman accepts the right password even then); unknown host name; an address this Mac cannot reach (with a pointer to the Local Network setting); an `http://` address on a port that only speaks HTTPS; an untrusted certificate; a redirect, with a button for the suggested `https://` address; not a Codeman server. A multi-user account that must change its password connects, and Codeman's own dialog asks for the new one. If the server page has not started showing within 15 seconds, or you press Cancel while it opens, the connect screen comes back with a notice. On a Mac whose WebKit is too old for Codeman it says so and Connect stays off (see Known limits). |
 | **Start Codeman** | On the This Mac tab, and when `http://127.0.0.1:<port>` or `http://localhost:<port>` answers nothing, one click runs `codeman web -d` (or `~/.codeman/app`) with your login shell's environment, so the server gets your real PATH (Homebrew, nvm) for the agents it spawns. zsh, bash and other POSIX shells run the start themselves; fish, nu, xonsh, tcsh and other shells only report their environment, and the start runs under `/bin/sh` with it. Offered for those two addresses only: `codeman web -d` listens on 127.0.0.1. |

+**The app runs the installer itself; Terminal is the fallback.** `install.sh
+--no-admin` puts Node.js and tmux in the home folder, so a This Mac install needs
+no password and therefore no terminal, and the two questions only a person can
+answer arrive as flags (`src/gui_install.rs`). The app downloads the installer
+once to a private folder, asks it what is on this Mac (`install.sh preflight`,
+which prints JSON and changes nothing) and draws its choices from that answer.
+So the app has no list of coding agents of its own: a new one appears without a
+new app, and the list always matches what the installer can really install
+here. The installer runs with the login shell's environment, so it finds what
+this person already has. The page sends only the agent's id, whether other
+devices may reach Codeman, and that password; the password reaches the
+installer through its environment, never its command line, where `ps` shows it.
+
+**The install outlives the app.** Its output goes to a file, never a pipe, and
+it runs in a process group of its own. With a pipe, quitting the app would kill
+the installer at its next write; in the app's group, launchd would kill it with
+the app. The file holds the whole run, so a page that was reloaded, or an app
+that was opened again, finds the process in `ps` and replays the file from the
+first line. That is why the app keeps no state about a run. A run that ends
+without the installer's last `done` line failed, and the first error it reported
+is the one shown: the ones after it are consequences.
+
+**Adding an agent is a run of its own.** `install.sh agent <id>` installs one
+agent and touches neither Codeman nor its service, so it may run next to a live
+server, which an install must refuse: the installer's service step would replace
+that server under its sessions. It has its own temporary folder, so `ps` tells the
+two apart: everything that reads a running install takes it to mean "Codeman is
+being installed", which an agent run does not. One run goes at a time, since both
+can write to the runtime folder. It asks `preflight` for the list like an install
+does, and both pass `--no-admin`: that flag decides which agents count as
+installable, so without it on both the page could offer one the run refuses. The
