iso: audit-sweep UID, bakery update, lockfile, welcome, autostart

Resolve MAIN_USER after deleting liveuser so Snapper and skel target the
installed account. Wrap bakery update with sudo -n/pkexec for /usr/local.
Pin bakery and bread-theme 0.7.4; require bread-emit and bread-module-host.
Make Calamares internet check non-blocking against breadway.dev. Autostart
breadlock listen. Smoke avahi-daemon.socket to match post-install.

+# AGENTS.md — Repo hygiene
+
+Scope: this file covers *repo hygiene* — branching, remotes, CI, cleanup. It is not project documentation. Product shape is [README.md](README.md).
+
+## What this repo is
+
+ISO + Calamares + skel. **No Cargo workspace. No `bos-settings/` member.**
+bos-settings (Tauri 2 + Svelte) and breadhelp are standalone bakery
+products. breadlock is the only bread\* pacman package.
+
+Live skel is `iso/airootfs/etc/skel`. `dotfiles/` is stale.
+
+## Branch model
+
+Single-trunk:
+
+- `main` — integration + release trunk. Land work via short-lived
+  `feature/*` / `fix/*` branches, then merge.
+- `stable` — marker only. CI fast-forwards it to the latest non-RC release
+  tag. Never merge into it by hand.
+
+There is no `dev` integration branch.
+
+## Remotes
+
+- `origin` — Forgejo (`ssh://git@100.66.238.26:2222/Breadway/bos.git`) — authoritative.
+- `github` — GitHub (`https://github.com/Breadway/bos.git`) mirror. Push
+  origin (and github when mirroring).
+
+`origin` is **not** GitHub.
+
+## CI
+
+- `.forgejo/workflows/*.yml` trigger on `push: tags: ['v*']` (or
+  path-scoped packaging triggers) — ordinary pushes to `main` run nothing
+  except those path filters. Tag a release to build the ISO.
+- `stable` is moved by the release-iso workflow, not by humans.
+- No build/lint/test CI runs on ordinary commits or PRs — test locally
+  before merging to `main`.
+
+## Cleanup
+
+- Delete feature/fix branches (local + remote) once merged. Check with
+  `git branch --merged main`.
+- Don't let merged branches accumulate.
+
+## Don't
+
+- Don't embed credentials in remote URLs — SSH or a credential helper only.
+- Don't leave the default branch pointed at a feature branch on
+  GitHub/Forgejo.
+- Don't bake an ISO (`sudo ./build-local.sh`) unless asked — lockfile/docs
+  work does not require it.
+- Don't tell users to `snapper rollback` blindly; GRUB pins
+  `rootflags=subvol=@`. Recovery is grub-btrfs reboot. Bakery desktop
+  apps on BOS are system-prefix `/usr/local` (`/etc/bakery/config.toml`);
+  snapper `@` snapshots include them. Do not move those bits back to
+  `~/.local` on the image (hermes / default bakery stay user-layout).

+is the original plan. Several sections below are historical and must not be
+taken as current:

+| Plan said | What the tree does now |
+|-----------|------------------------|
+| Cargo workspace with a `bos-settings/` member | This repo is ISO + Calamares + skel only. No Cargo workspace. |
+| `bos-settings` as an in-tree GTK4 app | Standalone bakery product, **Tauri 2 + Svelte**. |
+| bakery install in Calamares post-install | bakery binaries + breadhelp content are **baked into `/etc/skel` at ISO build time** from `iso/bread-lockfile.toml`. Missing bins fail the bake. |
+| `dotfiles/` is the live skel | Live defaults are `iso/airootfs/etc/skel`. `dotfiles/` is stale. |
+| A/B root swapping | **Future.** Today: btrfs + snapper + **grub-btrfs**. GRUB pins `rootflags=subvol=@`, so `snapper rollback` is not the user-facing recovery path. |
+| Work on `dev`; origin = GitHub | Single-trunk `main`; `stable` is a CI marker. `origin` = Forgejo, `github` = GitHub. |
+| `[breadway]` provides bakery/breadbar/bos-settings | `[breadway]` is breadlock + AUR republishes. Desktop apps are bakery. **Not shipped:** breadcast, breadarr. |
+| NVIDIA / A/B / Secure Boot / LUKS2 | NVIDIA proprietary is **unsupported**. A/B root swapping is **not implemented**. Secure Boot is **Setup Mode only** (self-signed `sbctl`). Disk encryption is **LUKS1** because GRUB cannot unlock LUKS2+Argon2id. |
+| `SigLevel = Required` on `[breadway]` | **No.** Forgejo's Arch registry has no pacman-compatible db signatures. `SigLevel = Never` is TLS only; flipping Required without a signed db breaks installs. `KEYS.asc` signs ISO SHA256SUMS, not the pacman repo. |

-## Component 3: `bos-settings` GTK4 App
+## Component 3: `bos-settings` (planned as GTK4)
+
+### Tech choices (original)
 
-### Tech choices
 - **gtk4-rs** (v0.11, v4_12 feature), no relm4 — plain GTK4 following breadman's pattern
-- **bread-theme** for palette + CSS (git dep: `github.com/Breadway/bread-ecosystem`)
-- Reads/writes each tool's own config file directly (no unified intermediate config)
-- Window: 960×640, sidebar 190px, `gtk4::Stack` for view switching — identical structure to breadman
+
+**What shipped:** Tauri 2 + Svelte in its own repo
+(`git.breadway.dev/Breadway/bos-settings`), distributed by bakery. This
+repo does not build it.
 
 ### Sidebar sections + views
 
-| Section | View | What it does |
-|---------|------|--------------|
-| **Apps** | bread | Edit `~/.config/bread/breadd.toml` |
-| | breadbar | Edit `~/.config/breadbar/` (style.css override, no TOML needed) |
-| | breadbox | Edit `~/.config/breadbox/config.toml` (context priority lists) |
-| | breadcrumbs | Edit `~/.config/breadcrumbs/breadcrumbs.toml` (profiles, networks) |
-| | breadpad | Edit `~/.config/breadpad/breadpad.toml` (model, reminders, calendar) |
-| **System** | Snapshots | `snapper list` output; rollback button calls `snapper rollback N` |
-| | Packages | `bakery list --installed`; update buttons call `bakery update <pkg>` |
-| | Hyprland | "Open config in editor" + monitor list from `bread.state.monitors()` |
-
-### Config loading pattern
-
-Each view has a dedicated `load_config(path) -> Result<T>` and `save_config(path, T) -> Result<()>` using `toml` crate. Config structs mirror each app's existing types (no duplication — import the `*-shared` crate where it exists, e.g. `breadpad-shared`). For apps without a shared crate (breadbox, breadcrumbs), define minimal local structs.
-
-### Snapshots view specifics
-
-- On open: runs `snapper list --output-cols number,date,description,pre-post` via `std::process::Command`, parses into table rows
-- Rollback: confirmation dialog → `snapper rollback <N>` → notify user to reboot
-- Delete: `snapper delete <N>`
-- No write access to `/` needed for list/rollback since snapper is configured with `ALLOW_USERS` for the main user
-
-### Packages view specifics
-
-- On open: reads `~/.local/state/bakery/installed.json` directly (no network)
-- "Check for updates": runs `bakery list` (triggers index refresh), compares versions
-- "Update all": runs `bakery update --all` in a subprocess, streams stdout to a log TextView
+The panel list is still roughly accurate; see README. Snapshots recovery
+should send users through **grub-btrfs reboot**, not `snapper rollback N`.
 
 ### Distribution
 
-`bos-settings` gets a `bakery.toml` and is added to the `bread-ecosystem` registry — installable standalone on any Arch/Hyprland system via `bakery install bos-settings`, not only as part of a BOS install.
+`bos-settings` has its own `bakery.toml` and is installable via

 ## Component 4: Default Dotfiles
 
-Minimal but functional defaults deployed at install time. These are opinionated starting points, not locked configs — users edit freely after install.
+Minimal but functional defaults. These live in `iso/airootfs/etc/skel`
+(`hyprland.lua` + JSON binds, not `dotfiles/hyprland/*.conf`).
 
-| File | Key content |
-|------|-------------|
-| `dotfiles/hyprland/hyprland.conf` | Monitor auto-detect, default keybinds, `exec-once` for breadd/breadbar/breadbox-sync |
-| `dotfiles/hyprland/keybinds.conf` | `$mod+Space` → breadbox, `$mod+N` → breadpad, `$mod+M` → breadman, `$mod+S` → bos-settings |
-| `dotfiles/bread/breadd.toml` | All adapters enabled, log_level=info |
-| `dotfiles/bread/init.lua` | Minimal: activates "default" profile on startup |
-| `dotfiles/breadbox/config.toml` | Single default context with common apps |
-| `dotfiles/breadcrumbs/breadcrumbs.toml` | Placeholder home profile (user fills in SSIDs) |
+Zero-config bakery apps survive with no extra skel files. breadcrumbs
+networks are user-filled after install — do not invent a full
+`breadcrumbs.toml` in-tree.
 
 ---
 
 ## Build Order
 
-1. **Dotfiles** — write default configs; these unblock installer testing immediately
-2. **Btrfs + snapper config** — write `post-install.sh`; test in a VM with `archiso` livecdbase
-3. **ISO profile** — archiso profiledef + package list + Calamares YAML; iterate in a VM
-4. **bos-settings** — start with Snapshots and Packages views (highest value, no app-specific config parsing needed), then add per-app views one at a time
+Historical. The ISO profile + skel + Calamares path is what this repo
+iterates on. bos-settings is developed in its own repo.
 
 ---
 
 ## Verification
 
-- **ISO**: Build with `mkarchiso -v -w /tmp/bos-work -o /tmp/bos-out iso/`; boot in QEMU (`qemu-system-x86_64 -cdrom bos.iso -m 4G -enable-kvm`); complete install; reboot into installed system; confirm all services running and bakery packages present
+- **ISO**: `sudo ./build-local.sh` (not a raw `mkarchiso iso/` — the bake
+  step is required). Boot in QEMU; complete install; confirm bakery bins and
+  `~/.local/share/breadhelp/content`.
 - **btrfs layout**: `btrfs subvolume list /` after install; confirm `@`, `@home`, `@snapshots`, `@log`, `@cache` exist
 - **snapper**: `snapper list`; run `pacman -Syu` and confirm two new snapshots appear
 - **grub-btrfs**: Reboot and confirm snapshot submenu in GRUB
-- **bos-settings**: `cargo build --release`; launch; confirm each view loads its config file; edit a value, save, re-open and confirm persistence; test rollback button in Snapshots view
+- **bos-settings**: built and tested in the bos-settings repo, not here

+**An update broke something (system still boots):** reboot → **GRUB

+A/B root swapping (SteamOS-style) is a **future** idea in DESIGN.md — it is

 **The system won't boot (broken GRUB / lost EFI entry):**
 
 1. Boot the BOS ISO and open a terminal (`SUPER+Return`).
-2. Mount the installed root and EFI, then chroot:
+2. Run `sudo bos-rescue`. It finds the installed btrfs `@` and the ESP,

+   installer uses (NVRAM + `--removable` + `grub-mkconfig`).

    arch-chroot /mnt

+# Hardware and recovery
+
+## GPUs
+
+BOS ships the generic **Mesa** stack. AMD and Intel work out of the box.
+
+The proprietary NVIDIA driver is **not on the ISO**. NVIDIA firmware is
+not on the image either (`linux-firmware-nvidia` stays commented out in
+`packages.x86_64`). Default Hyprland env is vendor-neutral.
+
+On first graphical login, `bos-first-boot` probes `lspci` / `/proc` and,
+if an NVIDIA GPU is present, writes `~/.local/state/bos/nvidia-offer.json`
+and notifies that the proprietary driver is not on the ISO. It does **not**
+install anything.
+
+The optional proprietary path is `bos-nvidia-setup` or the Settings →
+Updates NVIDIA button. That installs `nvidia` + `nvidia-utils` (never
+cuda) and writes `~/.config/hypr/nvidia.lua`. `hyprland.lua` dofiles that
+drop-in **only if the file exists**, so Mesa machines stay unchanged.
+Reboot after. Installing the packages by hand without the drop-in is not
+enough for a working Hyprland session.
+
+The same probe leaves a HiDPI hint at `~/.local/state/bos/hidpi-hint.json`
+when scale > 1 or the panel is dense; it never rewrites `monitors.json`.
+A VM without `/dev/dri` gets a notification only.
+
+## Recovery
+
+An update that breaks the system is recovered by **reboot → GRUB
+“snapshots” submenu** (grub-btrfs). `snapper rollback` will not change
+what GRUB boots (`rootflags=subvol=@`).
+
+`snapper rollback` swaps the default subvolume; the installed `grub.cfg`
+still boots `@`. Pick the grub-btrfs entry so the kernel command line
+matches the snapshot you want.
+
+BOS Settings → Snapshots lists snapshot number, date, and description so
+you know which GRUB entry to pick. It does not roll the running root back
+in place. Bakery desktop apps live under `/usr/local` on `@`, so those
+same snapshots include them.
+
+If the system will not boot (lost EFI entry / broken GRUB), boot the live
+ISO and run `sudo bos-rescue`. It mounts `@` + the ESP and offers the same
+`grub-install` NVRAM + `--removable` sequence as `post-install.sh`.
+
+A/B root swapping is not implemented. See the README Recovery section.

+# Signed `[breadway]` repo
+
+Today the ISO's `[Breadway.os.git.breadway.dev]` section is
+`SigLevel = Never`. That is TLS-only integrity: packages come from Forgejo's
+Arch registry, which does **not** serve pacman-compatible database
+signatures. `KEYS.asc` signs **ISO `SHA256SUMS`** and, once published, the
+`dl.breadway.dev/arch` database. It is **not** imported as a pacman repo key
+on the ISO yet. Do not flip `SigLevel` to `Required` on that section until
+a signed repo exists and has been verified; Required without signatures
+breaks the ISO and every installed system.
+
+The signed repo belongs at `https://dl.breadway.dev/arch`, not on Forgejo's
+registry. Forgejo publishing stays as it is (`package.yml` / packaging
+workflows PUT unsigned `.pkg.tar.zst` so existing Never installs keep
+working).
+
+## Stand up `dl.breadway.dev/arch`
+
+CI job: **Publish signed `[breadway]` repo**
+(`.forgejo/workflows/signed-repo.yml`), host runner on hestia — **no
+container**, so it can write `/srv/breadway-dl` like bakery releases.
+breadlock `package.yml` uses `archlinux:latest` and cannot see host `/srv`.
+
+Use the same release-signing key already in CI:
+
+- Public half: [`KEYS.asc`](../KEYS.asc)
+  (`5620 3B86 A110 695A E7F3  1093 4AF3 323D 678E B5E2`,
+  `releases@breadway.dev`)
+- Private half: the `GPG_PRIVATE_KEY` Forgejo secret (armoured secret key,
+  no passphrase). Same secret `release-iso.yml` uses to sign `SHA256SUMS`.
+  The workflow **fails** if this secret is missing.
+
+Layout (example for `x86_64`):
+
+```
+https://dl.breadway.dev/arch/x86_64/
+  breadlock-<ver>-1-x86_64.pkg.tar.zst
+  breadlock-<ver>-1-x86_64.pkg.tar.zst.sig
+  breadway.db
+  breadway.db.sig
+  breadway.files
+  breadway.files.sig
+```
+
+On disk: `/srv/breadway-dl/arch/x86_64/` (nginx already serves
+`/srv/breadway-dl` as `https://dl.breadway.dev/`).
+
+The job collects the current ISO `[breadway]` set from the Forgejo Arch
+registry (breadlock + calamares, zen-browser-bin, bibata-cursor-theme-bin,
+zsh-theme-powerlevel10k, yay-bin). Leftover bakery-channel pacman packages
+still sitting in that registry are **not** copied. Optional
+`BREADWAY_PKG_DIR` on the runner overrides individual files.
+
+Then it detach-signs each `.pkg.tar.zst` as a **binary** sidecar (pacman
+wants `.sig`, not armoured `.asc`) and builds the database with
+`repo-add -s`:
+
+```sh
+export GNUPGHOME=/tmp/gnupg-breadway-repo
+mkdir -m 700 -p "$GNUPGHOME"
+printf '%s\n' "$GPG_PRIVATE_KEY" | gpg --batch --import
+
+gpg --batch --yes --local-user releases@breadway.dev \
+    --detach-sign breadlock-<ver>-1-x86_64.pkg.tar.zst
+# → breadlock-<ver>-1-x86_64.pkg.tar.zst.sig
+
+cd /srv/breadway-dl/arch/x86_64
+repo-add -s -k releases@breadway.dev breadway.db.tar.gz *.pkg.tar.zst
+```
+
+`repo-add -s` writes `breadway.db.tar.gz.sig` (and the `.files` pair).
+Pacman fetches `<section>.db` + `<section>.db.sig` from `Server`.
+
+## Dispatch the workflow
+
+Forgejo UI: **Actions → "Publish signed [breadway] repo" → Run workflow**.
+Select `main`.
+
+API (`workflow_dispatch`):
+
+```sh
+curl -fsS -X POST \
+  -H "Authorization: token ${RELEASE_TOKEN}" \
+  -H "Content-Type: application/json" \
+  "https://git.breadway.dev/api/v1/repos/Breadway/bos/actions/workflows/signed-repo.yml/dispatches" \
+  -d '{"ref":"main"}'
+```
+
+It also runs after the in-repo AUR republish workflows complete
+(`calamares` / `bibata` / `powerlevel10k` / `yay-bin`). breadlock lives in
+another repo; that job can fire this one with `repository_dispatch` event
+`publish-signed-repo` (or dispatch from the UI after a breadlock tag).
+
+## Verify
+
+Confirm the signed db is actually served **before** touching ISO
+`SigLevel` or `Server`:
+
+```sh
+curl -fsSIL https://dl.breadway.dev/arch/x86_64/breadway.db
+curl -fsSIL https://dl.breadway.dev/arch/x86_64/breadway.db.sig
+```
+
+Both must be HTTP 200. A 404 on `breadway.db.sig` means do **not** flip
+`SigLevel` to `Required`.
+
+Import `KEYS.asc` and check the detached signatures:
+
+```sh
+gpg --import KEYS.asc
+curl -fsSL -o /tmp/breadway.db https://dl.breadway.dev/arch/x86_64/breadway.db
+curl -fsSL -o /tmp/breadway.db.sig https://dl.breadway.dev/arch/x86_64/breadway.db.sig
+gpg --verify /tmp/breadway.db.sig /tmp/breadway.db
+```
+
+On a throwaway Arch box (not the ISO tree):
+
+```sh
+sudo pacman-key --add KEYS.asc
+sudo pacman-key --lsign-key 56203B86A110695AE7F310934AF3323D678EB5E2
+
+# Temporary /etc/pacman.conf snippet — do not commit this to the ISO:
+# [breadway]
+# SigLevel = Required
+# Server = https://dl.breadway.dev/arch/$arch
+
+sudo pacman -Sy
+```
+
+`pacman -Sy` must fetch `breadway.db` + `breadway.db.sig` without
+"missing or invalid signature". Then `pacman -Si breadlock` (and the AUR
+republishes) should list the `[breadway]` section.
+
+## breadlock `package.yml` sidecar
+
+[`breadlock` `package.yml`](https://git.breadway.dev/Breadway/breadlock/src/branch/main/.forgejo/workflows/package.yml)
+still `makepkg`s and PUTs the archive at Forgejo's registry. That path
+stays; Never installs keep working. The signed tree is rebuilt by the bos
+workflow above (registry fetch + sign + `repo-add -s`), not by writing
+`/srv` from breadlock's container.
+
+## After the signed repo exists
+
+Only after `https://dl.breadway.dev/arch/x86_64/breadway.db.sig` HEADs 200
+and the verify commands above succeed:
+
+1. Import `KEYS.asc` into the ISO keyring (`pacman-key --add` + `--lsign-key`).
+2. Point `[breadway]` `Server` at `https://dl.breadway.dev/arch/$arch`.
+3. Only then flip that section to `SigLevel = Required`.
+
+Do not do those three steps against Forgejo's registry. See
+`iso/pacman.conf` and `iso/airootfs/etc/pacman.conf`. This tree does
+**not** change either file.
