 - `programs.gamescope.capSysNice = true` installs gamescope as a setcap wrapper
   in `/run/wrappers/bin` instead of the system profile. That path precedes the
   system profile on `PATH`, so `steam-gamescope` still resolves it.
+- greetd gives the session the VT for its standard streams, so anything the
+  Steam session prints as it dies is erased the moment the greeter repaints.
+  `initial_session` therefore runs the launcher under `systemd-cat`, and the
+  output is readable after the fact with `journalctl -b -t steam-session`.
+
+### When the television lands on ReGreet instead of Steam
+
+greetd starts `initial_session` **once per boot** — the check is the presence of
+`/run/greetd.run` — and if the session process starts and then exits, greetd
+falls through to `default_session`, i.e. ReGreet. A gamescope that dies on
+startup is therefore indistinguishable from autologin never having run, unless
+the logs are read:
+
+```sh
+journalctl -b -t steam-session   # what the session itself said
+journalctl -b -u greetd          # whether greetd started it at all
+ls -l /run/greetd.run            # exists => greetd has already had its one go
+```
+
+If greetd never even reaches the session, it prints `unable to start greeter`
+and **exits** — there is no greeter to fall back to and the screen stays blank.
+Recover over SSH (`modules/ssh.nix`), or hold space at power-on and boot the
+previous generation.
+
+To reproduce a session failure by hand, switch to a free VT and run
+`steam-gamescope` there. Running it from inside Sway is not the same test:
+gamescope picks its nested Wayland backend when `WAYLAND_DISPLAY` is set, and it
+is the DRM backend — the one the boot session uses — that is in question.
 
 The greeter is **Dvorak**, like every other host here (`modules/sway.nix` forces
 `XKB_DEFAULT_VARIANT=dvorak` on cage). Only relevant if someone else has to type
 a password.

+- Any output running at 4K is forced to **scale 2** (1920x1080 logical). Sway's
+  config cannot key an output rule on resolution, so a small user service
+  applies it at session start and again on every output event — which is what
+  makes it survive the TV being switched off and on.
+- The emulators inhibit idle **while focused**, not only while fullscreen.
+  PCSX2 and Dolphin default to borderless-windowed rather than compositor
+  fullscreen, so the generic `inhibit_idle fullscreen` rules never fired and
+  swaylock cut in mid-game.
+
+Neither applies in the Steam session: `swayidle` is a home-manager user service
+wanted by `graphical-session.target` and conditional on `WAYLAND_DISPLAY`, and
+the gamescope session starts neither, so nothing locks the screen in Big
+Picture.
+
+### Adding non-Steam titles to Big Picture
+
+RetroArch, PCSX2, Dolphin and Clone Hero are installed system-wide but are not
+Steam titles. Added as Steam shortcuts they appear in Big Picture and inherit
+Steam Input, so the controller works in them without further configuration.
+
+Steam's own **Games → Add a Non-Steam Game** is the documented route and is also
+the one that does not work here: the dialog never appears at all. That dialog's
+file browsing goes through the XDG desktop portal `FileChooser` interface, and
+when the portal is unreachable the client falls back to a legacy chooser that is
+blank or inert — Valve
+[#9447](https://github.com/ValveSoftware/steam-for-linux/issues/9447), not fixed.
+Check the portal side before blaming the client:
+
+```sh
+busctl --user introspect org.freedesktop.portal.Desktop \
+  /org/freedesktop/portal/desktop | grep FileChooser
+```
+
+`modules/sway.nix` enables `xdg-desktop-portal-gtk`, which is the backend that
+implements `FileChooser` (`xdg-desktop-portal-wlr` implements only screenshot
+and screencast), and the generated `sway-portals.conf` routes everything but
+those two to `gtk`. If the interface is missing from the introspection above,
+the backend is not running and that is the fault to chase.
+
+Independent of the dialog, `steamtinkerlaunch` writes `shortcuts.vdf` directly:
+
+```sh
+# Steam must be closed -- it rewrites shortcuts.vdf on exit.
+steamtinkerlaunch addnonsteamgame -an="RetroArch"  -ep="$(command -v retroarch)"

+### When Steam will not register the library folder
+
+Current behaviour on this host: the file picker opens, Steam creates the
+directory structure at `/srv/games/steam`, and the library then never appears in
+the Storage UI. So this is not the portal problem the non-Steam-game dialog has
+— the picker works and Steam can write. The failure is in the validation Steam
+runs before it records the folder in `libraryfolders.vdf`.
+
+That validation is a write-and-execute probe: Steam drops a
+`.steam_exec_test.sh` in the candidate folder, marks it executable and runs it.
+If either step fails the folder is silently dropped, which is
+[#8450](https://github.com/ValveSoftware/steam-for-linux/issues/8450) and is
+usually a `noexec` mount or an ownership problem — neither of which is obviously
+true here, since `/srv` is on the ext4 root and the tree is
+`lyrathorpe:users` 2775.
+
+Reproduce the probe **inside Steam's FHS sandbox**, which is where the client
+actually runs it — `steam-run` is installed by the steam module for exactly this
+kind of thing:
+
+```sh
+steam-run sh -c '
+  printf "#!/bin/sh\nexit 0\n" > /srv/games/steam/.steam_exec_test.sh &&

+  echo "probe ok"
+'
+rm -f /srv/games/steam/.steam_exec_test.sh
+```
+
+Then ask the client directly. Steam's console reports a reason where the UI
+says nothing — open Steam with `steam -console`, pick the **CONSOLE** tab and
+run:
+
+```
+library_folder_add /srv/games/steam
+```
+
+The directory must already exist and be writable by the user Steam runs as,
+which `systemd.tmpfiles` guarantees; the command does not create it. Whatever it

+doubt, that is the ear to test it against. What it means in practice:
+
+- **Lead with the number.** Let it carry the weight. Do not add an adjective to help it.
+- **State consequence as fact, not as warning and not as a joke.** "It stops working and
+  nothing tells you why", never "you'll be debugging it at midnight".
+- **Correct a soft word with the hard one, out loud.** Four minutes is not a blip.

+## Worked examples
+
+The sections above describe the voice. Descriptions do not produce it — these do. Each
+pair is the same content twice: the neutral register that keeps reappearing, then the
+target. Match the second of each pair, not the adjectives above it.
+
+The subject matter is deliberately spread across different working contexts — a personal
+Nix flake, service and release work, cluster operations, dependency-PR triage — because
+the register does not change with the repository. It does not soften for personal
+projects or stiffen for work ones.
+
+Three faults to watch for, because they are the ones that keep appearing:
+
+- **Writerly.** Balanced clauses, em-dash asides, sentences built for rhythm. Short
+  declaratives instead. Closer to a work order than to prose.
+- **Serving.** Ending on an offer, hedging a judgement, asking permission to have an
+  opinion. State the finding; do not audition it.
+- **Characterless.** Procedurally correct and empty. The engineer has views about the
+  work, volunteers them unasked, and is willing to say a thing was a waste of an evening.
