+**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 only the CLI management routes clear that, so the app says so on its last screen and never restarts the service for it. ⚠️ `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.
