docs: #114 ships as document-only; record 2026-07-17 triage rulings

Live triage with Bernardo. #114 (greeter ignores per-device layouts):
ruled document-only — a kernel VT has exactly one keymap, so tuigreet
structurally cannot honour settings.keyboard.devices. README gets the
"Greeter keyboard layout" note after the home.nix options table,
RECOVERY.md §2 a one-line pointer for the password-rejected case,
ROADMAP's #145 cross-ref updated, BACKLOG entry deleted.

Also recorded: #120 stays deferred (cachix likely first step when
promoted); #134 decided — Nomarchy carries nixpkgs-unstable, unstable.*
via overlay, home-scope only — rewritten into NEXT; #143 upstream check
(rofi#2317 still open, no response) noted in the item.

Verification: V0 — docs and backlog only, prose reviewed in place.

 **This item is now a watch, not work:** the only thing to do is check
 rofi#2317, and take the fix when a release carries it. If it is still open at

+### 134. `unstable.<pkg>` in the downstream — decided, build it
+
+**Decided 2026-07-17 (Bernardo): Nomarchy carries the channel.** Add a
+`nixpkgs-unstable` input to the distro flake and expose it through
+`overlays.default` as an `unstable` attrset, so
+`home.packages = [ unstable.lmstudio ];` just works — downstream stays one
+locked input and `nomarchy-pull` still moves it. Scope is **home packages
+only**; no `unstable.*` surface in system.nix, no `stable.` synonym for now.
+The input rides in the eval unconditionally (an unused input still locks +
+fetches — accepted). Original diagnosis stands: `mkFlake` has no overlay
+seam and `homeConfigurations` uses mkFlake's own `pkgs`, so nothing short of
+the distro carrying the channel keeps the user out of `fetchTarball` pinning.
+
+Costs accepted with the ruling, to be stated in docs, not hidden: lock bumps
+now move two channels (VERIFICATION §5 full-checklist applies to both); a
+user who reaches for `unstable.` pays a second stdenv/glibc in their closure
+(measured: lmstudio shares only ~690 of ~3.7–4k paths); and nothing upstream
+tests pinned-Nomarchy + unstable-app together — the README needs an explicit
+"you own this combination" paragraph. Ship with a commented example in
+`templates/downstream/home.nix` (opt-in convention) and a README table note.
+Pass = flake check green + a V1 build of the template HM closure with one
+`unstable.` package enabled. Related: #133.

-### 134. `unstable.<pkg>` in the downstream — a newer app without a second flake
-
-Bernardo 2026-07-15, wanting a newer LM Studio (pinned 0.4.15-2 vs unstable
-0.4.19-2) and disliking the only path that works today. There is **no seam**:
-`mkFlake` takes `src`/`username`/`hardwareProfile`/`system` only, and
-`homeConfigurations` is built from mkFlake's own `pkgs` (`inherit pkgs`), so a
-`nixpkgs.overlays` in system.nix cannot reach a home package. The user is left
-hand-pinning a `fetchTarball` rev+sha256 in home.nix (verified working) — a
-second pin with no lock, which is exactly the Nix expertise the distro exists
-to spare them. Sketch: `home.packages = [ unstable.lmstudio ];`, and maybe
-`stable.` as an explicit synonym for today's bare `pkgs`.
-
-The shape that keeps the promises: Nomarchy carries the `nixpkgs-unstable`
-input **itself** and exposes it through `overlays.default` as an `unstable`
-attrset, so downstream stays **one input**, stays locked, and `nomarchy-pull`
-still moves it. Cost/questions to settle before building:
-- Lock churn: every lock bump now moves two channels, and the full-checklist
-  rule (VERIFICATION §5) applies to both.
-- Duplication: measured — pinned vs unstable lmstudio build closures share
-  only 690 of ~3.7–4k paths (separate stdenv bootstrap). Opt-in per package,
-  but a user who reaches for it pays a second glibc/stack in the closure.
-- "Tested together upstream" weakens by construction: nothing validates
-  pinned-Nomarchy + unstable-app. Needs an explicit, documented "you own this
-  combination" line, not silence.
-- Does `unstable` belong in the eval by default, or only when referenced?
-  (An unused input still locks + fetches.)
-- Scope: home packages only, or system.nix too?
-
-Alternative if that is too much surface: give `mkFlake` an `overlays ? []`
-param (one-line seam, user still owns their own input/pin — cheaper for us,
-still expert-only for them). Related: #133.

-### 114. Greeter ignores per-device keyboard layouts
-
-Found by Bernardo 2026-07-14: logging out while docked lands on tuigreet,
-where his external keyboard (remembered as `us` via
-`settings.keyboard.devices`) types the session layout `gb` — so the password
-prompt fights him. Not a regression and not docking-related: per-device
-layouts are applied with `hyprctl keyword device[<name>]:kb_layout`, which
-only exists inside a running Hyprland session, while tuigreet draws on a
-kernel VT whose single keymap comes from `console.useXkbConfig` ←
-`services.xserver.xkb.layout`. A VT structurally cannot do per-device
-layouts, so this is a design gap, not a bug to patch. Options, cheapest
-first: (a) document it and stop there; (b) a greeter layout-cycle key
-(tuigreet has no such feature — would need the keymap swapped under it);
-(c) host tuigreet inside a small Wayland compositor (cage/labwc), which
-*does* get per-device XKB and would let the greeter honour the same
-in-flake state the session uses — real work, and it changes the greeter's
-whole rendering path (`modules/nixos/greeter.nix` themes tuigreet through
-the 16 ANSI console slots, so (c) is not a drop-in). Worth deciding whether
-the greeter is meant to be layout-aware at all before costing it.
