Bernardo Magri 46af2f0632 feat(ci): checks-on-push workflow (Forgejo Actions, eval tier)
.forgejo/workflows/check.yml runs on every push to main/v1 (+ manual
dispatch): nix flake check --no-build (full module-system eval incl.
the downstream template through mkFlake), py_compile of
nomarchy-theme-sync, and bash -n over tracked .sh files. The always-on
net under direct-to-main pushes — first slice of the ROADMAP lock-bump
CI item.

Scoped to the eval tier deliberately: the instance's runner is an
act_runner docker container (no systemd, no /dev/kvm — established
from the legacy repo's .gitea/workflows/check.yml, which ran 57 times
on it), so the checks.* VM suite and real builds can't run there. A
commented vm-checks job documents the KVM-runner upgrade path; the
legacy workflow's container gotchas (nixbld setup for the single-user
installer, sandbox=false for Stylix IFD, Nix pinned 2.31.5 vs
lazy-trees, no JS actions past node20) are carried over verbatim in
the header. docs/TESTING.md §1b documents what a green run does and
does not mean.

Verified: V0 locally (the same check commands, minus the container
Nix install) + YAML parse. A real green run depends on the runner
still being registered — not API-visible unauthenticated, so that is
queued as [human] BACKLOG item 20.

Memory — durable lessons, learned the hard way

Curated, not append-only: one line per fact, newest at the top of its section; delete entries that stop being true. Details usually live in a docs/ROADMAP.md decision record — pointer given as (§ item). Add a fact here the moment a debugging session teaches you something a future iteration would otherwise rediscover.

Testing & VM recipes

  • CI (.forgejo/workflows/check.yml) is eval-tier only: the Forgejo act_runner is a docker container (no systemd, no /dev/kvm). Container gotchas are documented in the workflow header (single-user Nix + nixbld users, sandbox=false for Stylix IFD, Nix pinned 2.31.5 vs lazy-trees, no JS actions past node20) — learned over the legacy repo's 57 runs; read them before touching the workflow.
  • Reusable headless VM harness: checks.* via runNixOSTest — existing examples to crib from: distro-id (boots + switch-to-configuration dry-activate), hardware-toggles (kernel cmdline/PAM assertions), battery-charge-limit (fake Mains adapter via test_power, real udev uevent, InvocationID change proves the restart).
  • Themed-desktop screenshots work headlessly: software-GL Hyprland (LIBGL_ALWAYS_SOFTWARE on virtio-gpu) + machine.screenshot() QMP dump — prototyped 2026-06-19, kept as the fallback for theme previews (§ Visual theme picker).
  • Hyprland/Ghostty need guest GL (virtio-vga-gl, gl=on) in interactive QEMU or the session won't start; black screen ≈ missing GL (docs/TESTING.md § gotchas).
  • No KVM = slow, not broken; don't read slowness as failure.

Known-broken / watchlist

  • btrfs-assistant 2.2 segfaults on launch (nixpkgs 26.05, libbtrfsutil.so.1.4.0 ABI mismatch; crashes on hardware too, not a VM artifact). nomarchy-snapshots fzf flow is the shipped fallback; re-check on every lock bump (§ Snapshot browse/restore; BACKLOG NOW#2).
  • NixOS release bump is a trap: the discarded attempt (branch deleted 2026-06-22) hit a Hyprland OOM blocker; a redo is a deliberate v2, never part of routine lock bumps.
  • theme-state.json is git-tracked inside an 86 MB flake tree, so every state write re-copies the source before eval — the wallpapers-artifact split (BACKLOG LATER) is the decided fix (§ Faster switches).

Gotchas (cost a debugging session once)

  • Never kill a Wayland session-lock client (hyprlock): its crash failsafe drops to a tty instead of unlocking (§ Hibernate double-unlock).
  • rofi element-icon size is one value = a square cell; WxH silently collapses and non-square icons letterbox — pre-crop images square at build (§ Visual theme picker).
  • WirePlumber 0.5 monitor rules can only early-match device.api; device.product.name etc. bind after the rule runs — surgical libcamera scoping is impossible (§ Webcam).
  • hyprctl switchxkblayout is a global layout flip; per-device isolation needs device[<name>]:kb_layout keywords (§ Keyboard layouts).
  • Waybar's clock captures the timezone at construction — a zone change needs SIGUSR2 (watcher in timezone.nix) (§ Automatic timezone).
  • Waybar persistent_workspaces (underscore) is dead syntax silently ignored; the hyphen form is honoured and renders phantom workspaces (§ Waybar shows non-existent workspaces).
  • GTK4/libadwaita/Qt6 read light/dark from the portal's org.freedesktop.appearance color-scheme (dconf), not Stylix polarity (§ GTK/Qt ignore the theme's mode).
  • Update order matters downstream: sys-update (lock) before home-update, or desktop changes are silently skipped against the old lock (README § 3).
  • grub loadfonts every .pf2 in a theme dir — reuse a bundled DejaVu rather than shipping fonts (§ Distro branding).
