home/desktop-env: swap metis terminal from Ghostty to Foot#56
Merged
Conversation
ADR-028 named Ghostty as the metis terminal — inherited from the `tier3-desktop-deferred` stack and carried unexamined into the current decision. Operator's actual intent is Foot on Linux desktop hosts, with Ghostty reserved for macOS clients. Caught while drafting slice-4 research, before slice 4 itself landed. Source-side surgery: - `home/core/nixos/ghostty.nix` deleted. - `home/core/nixos/foot.nix` created (programs.foot.enable + a comment block flagging Stylix's hardcoded dpi-aware = "no" and the programs.foot.settings override-conflict path for future reference). - `home/core/nixos/niri.nix` keybind swap: `Mod+T → ghostty` → `Mod+Return → foot`. The key change is adjacent — `Mod+Return` is the tiling-WM canonical for terminal-launch (i3/sway). - `home/core/nixos/bundles/desktop-env.nix` import list + comments updated. - `home/core/nixos/dms.nix` one comment reference updated. - `home/core/shared/bundles/theming.nix` gains `foot.enable = true` in the central Stylix-target whitelist (preserves the single-source-of-truth for "where does Stylix theming live"). Inert on non-desktop hosts because Stylix gates the target on `programs.foot.enable`. Docs-side surgery: - ADR-028 Decision + Implementation references updated; appended a `## History` section documenting the swap and rationale (Foot is Wayland-native, lighter, aligned with niri's wlroots/smithay lineage; Ghostty retained for macOS clients via the unchanged `modules/core/shared/ghostty-terminfo.nix` Mac-client-rendering posture and a future `home/core/darwin/` Ghostty module for the mac-mini onboarding epic #11). Line 14's `tier3-desktop-deferred` tag reference is preserved verbatim — historical, not current. - `docs/decisions/README.md` ADR-028 index row. - `docs/nix-config-prd.md`, `CLAUDE.md`, `TODO.md` synced. `nix flake check` green. Peer-reviewed; three follow-on fixes folded back in: Stylix-target location moved from leaf module to shared theming bundle (preserving the explicit-whitelist pattern); foot.nix gains a defensive comment about Stylix's settings overrides; the ADR-028 History "files touched" list trimmed (git already records that). Bundle isn't composed into metis yet — that's slice 4 work. This PR amends bundle contents only; no currently-active host config changes.

Summary
Course-correction caught while drafting a slice-4 research prompt: ADR-028 named Ghostty as the metis terminal, inherited from the
tier3-desktop-deferredstack. Operator's actual intent is Foot on Linux desktop, Ghostty on macOS clients only. Slice 3 (the desktop-env scaffold, #44/#55) had landed with Ghostty; slice 4 had not, so the surgery is bounded.Adjacent change:
Mod+T → ghosttykeybind becomesMod+Return → foot(tiling-WM canonical for terminal-launch).Files (11)

Foot is Wayland-native, lighter weight, and aligned with niri's wlroots/smithay lineage. Ghostty is retained for macOS clients via the unchanged
modules/core/shared/ghostty-terminfo.nixMac-client SSH-rendering posture, and a futurehome/core/darwin/module will install the Ghostty binary on mac-mini/mba (per epic #11). The Linux/Darwin split is now: Linux desktop = Foot; macOS client = Ghostty.Test plan
