Nomarchy/agent/BACKLOG.md

Backlog — the prioritized task queue

This is the only executable work list for agents. Product themes and v1.0 intent live in docs/VISION.md; design history in docs/ROADMAP.md; map in docs/README.md and agent/README.md.

Rules:

• Agents take the topmost actionable item (see LOOP.md). Finished items are deleted here — the journal + git log are the record; durable design notes get a ✓-entry in docs/ROADMAP.md (and/or a note in VISION) if worth keeping.
• Item numbers are stable IDs — never renumbered or reused. A gap in the sequence means shipped (or dropped) work; new items take the next free number regardless of tier.
• Tags: [blocked:hw] needs real hardware (see HARDWARE-QUEUE.md) · [human] needs Bernardo · [stuck] two failed attempts, needs help · [big] must be split before starting.
• Agents may append to PROPOSED and Decisions freely (include VISION § … or ROADMAP § … when relevant); only Bernardo moves items out of PROPOSED into the tiers.

Live ISO / install hardware findings — Acer Aspire M5-481T + Dell XPS 9350

Bernardo, real installs 2026-07-13–14 (photos of the install end screens and post-boot sessions). Preserve separation: the installer bake failure and the flake pin are different root causes even when they show up on the same machine. (Terminal / Ghostty-on-Acer → shipped as Kitty-only, #95.)

127. [blocked:hw] Docked idle: black screens, no wake, undock does not restore panel

Bernardo 2026-07-15 (AMD dev box, docked): left the laptop docked; after a few minutes of idle it appeared to "sleep". Then:

1. External keyboard/mouse did not wake any display.
2. Unplugging the external monitor did not turn the laptop panel back on (dock mode has eDP disabled — undock should re-enable it).
3. The machine was still alive: Caps Lock LED toggled on the keyboard.

This also killed a long agent session (looked like a "crash" from the outside). Separate from awake undock recovery (HARDWARE-QUEUE round 8): the failure is idle while docked, then no path back to a usable panel.

Likely shape (code-side, unconfirmed on the incident): on AC, hypridle does not call systemctl suspend (onAc || suspend — only battery suspends at 15 min). Idle path is lock @5 min + dpms off @10 min (modules/home/idle.nix). Caps Lock working fits DPMS/lock blackout better than deep S3. Dock mode has already disabled eDP; recovery then needs either (a) input → hypridle on-resume / dpms on on the external, or (b) undock → nomarchy-display-transition undock re-enabling the panel. Both failed. after_sleep_cmd only does hyprctl dispatch dpms on and never re-enables a disabled internal.

Progress 2026-07-15:

• Recovery tooling: undock ends with dpms on; nomarchy-display-wake / nomarchy-display-dump (SUPER+SHIFT+D; TTY if it works).
• Mitigation (shipped): do not DPMS-off when docked — if any laptop internal (eDP/LVDS/DSI) exists in monitors all but is not enabled, the 10 min listener skips blanking. Lock at 5 min still runs; undocked laptops still DPMS-off as before. Bernardo: Ctrl+Alt+F3 did not yield a usable TTY on the original brick, so prevention > dump path.
• Revisit later (LATER): intentional DPMS-when-docked once wake is proven trustworthy (monitor power-save without a brick).

Pass (current mitigation): docked on AC, idle past 10+ min → external stays lit under hyprlock (journal: dpms-off skipped: docked); undocked still blanks at 10 min and wakes on input. Full original pass (wake after DPMS-while-docked) deferred to the LATER revisit.

NEXT

129. Permanent guard for the GTK button-colour trap (#98 follow-up)

The #98 regression (destructive-action at 1.03:1, invisible) was caught only by rendering a dialog — every scripted check was green, because the bug lives in adw-gtk3's mix(@destructive_color, alpha(currentColor,…)) background, not in our CSS. tools/theme-shot.nix is deliberately not a CI gate (full-desktop VM), so add the cheap static half: assert that for every theme, any rule that pins a button label colour also pins that button's background-color — i.e. no pinned label may sit on a currentColor-derived background. Guards the class, not the instance. The scratch render harness that found it is worth promoting to tools/dialog-shot.nix as a maintainer tool alongside theme-shot.

130. GTK accent buttons sit at ~2.7:1 in light themes

Fallout noted while fixing #98: in light palettes the suggested/destructive labels are base00 (cream) on saturated accent/bad — summer-day measures 2.72:1 (suggested) and 2.74:1 (destructive), under AA 4.5 and even under the 3:1 large-text floor. Not a regression: upstream adw-gtk3 does the same (color: white on the accent), so we currently match GNOME. Decide whether Nomarchy holds itself higher — darker label, or a darker accent mix for light palettes — and note tools/check-theme-contrast.py covers palette pairings only, never GTK widget surfaces. [human] for the aesthetic call.

131. Recovery cost labels truncate on 1366-wide panels

#111 gave Recovery scope-first labels that carry the cost inline — "Desktop generation — themes & home config (instant, reversible)" (462px in Inter 11) and "System boot generation — older NixOS (reboot, then pick in boot menu)" (509px). The picker is width: 40%, so text room is ~668px at 1920 (fits) but only ~446px at 1366 — both long labels ellipsize, and the cost hint is exactly the part that gets cut. The Acer Aspire M5-481T (1366×768) is an active QA machine, so this is live, not theoretical. Options: shorten to "Desktop generation (instant)" and put cost in a rofi -mesg line, widen the picker for narrow screens, or let rofi wrap. Measured, not observed — the VM renders menu geometry unfaithfully (see #132); confirm on the Acer.

132. VM cannot judge rofi menu geometry

The guest renders the picker with icons at roughly a quarter of ui.iconSize (44 → ~10px) and rows short enough that a 6-row root clips its last entry behind a scrollbar, though lines = 8 and dynamic = true should fit it. Root is unchanged since before #105, so this is the guest's font/icon environment, not a regression — but it means theme-shot.nix/menu-shot screenshots are trustworthy for menu content and not for spacing, icon size, or truncation. Either fix the guest (fontconfig + icon cache in the test node) or document the gap in docs/TESTING.md §5 so the next agent does not chase it — right now nothing warns them.

133. No check pins the #107 legacy-name compat shim

lib.mkFlake, doctor and lifecycle all still accept theme-state.json, and nomarchy-state-sync migrates it on write — but nothing in checks.* evaluates a checkout that has only the legacy name, so the shim can rot silently while every check stays green. It is load-bearing until every existing machine has taken one menu write. Add a cheap eval check: a fixture dir with theme-state.json only → mkFlake resolves it; plus the write-side migration (state.json created + git-staged, legacy git rm'd). Proven by hand 2026-07-15 (drvPaths identical across the rename) — this just keeps it proven. Delete together with the shim + the nomarchy-theme-sync alias.

120. A netinstall ISO, next to the fat offline one

Bernardo 2026-07-14, after seeing the measured size: keep the current ISO exactly as it is — the guaranteed offline install is the feature it buys — and ship a much lighter netinstall variant alongside it. Two products, one distro: "works on a plane" and "8 GiB is absurd to download" are both true, and a second target settles them without compromising either.

Measured facts (2026-07-14), so this starts from numbers, not vibes. (These stand as measured: #121 would have cut ~0.67 GiB of duplicate chromium from them, but it was reverted — decided against, ROADMAP § one chromium, not two. If a netinstall ships, revisit it: the duplicate is worth ~195 MiB of download, which is this item's whole currency, even though it is worth almost nothing on disk or on the ISO.)

Read this before using the numbers below. They are closure arithmetic, and #121 proved the hard way that closure size is neither disk size nor image size: removing a 687 MiB path shrank the ISO by 8 KiB, because mksquashfs dedupes duplicate files and auto-optimise-store hardlinks them on disk. So a change that looks like it sheds gigabytes of closure can shed nothing off the actual image. Measure the artifact — build the ISO and stat it. The corollary cuts the other way and is the good news for this item: what dedupe cannot help is the wire, so a netinstall's download is the one figure closure/NAR size predicts honestly (nix path-info --store https://cache.nixos.org --json gives the real downloadSize).

• Current ISO 8.078 GiB compressed; 18.03 GiB of store uncompressed (zstd -19, 2.23:1 — compression is already near-max, not the lever).
• The offline pin (system.extraDependencies, 60 roots: a representative installed system + the template HM closure + all flake inputs) is 4.02 GiB uncompressed of that — only ~22%. Dropping it entirely still leaves a ~13.3 GiB desktop → roughly 6 GiB compressed at the same ratio. So "no pin" alone is NOT the lighter ISO — this is the trap to avoid.
• The desktop's own top weights: libreoffice 1457 MiB, initrd 1369, linux-firmware 770, chromium 1391 (two builds — #121, left in), llvm-lib 540, bibata-cursors 322, mesa 264, mbrola-voices 259, nerd-fonts ~420 combined. Note what that list implies: no single lever gets a desktop ISO under ~4 GB — which is the case for (b) below.

So the real decision is what a netinstall ISO IS, and it should be settled first ([human]): (a) the full try-before-install desktop minus the pin (~6.3 GiB — barely lighter, probably not worth a second target); (b) a TUI installer only, no desktop (~1 GiB, the actual "netinstall" in the Debian sense) which drops "try before install" from that medium — the fat ISO still offers it; (c) a middle desktop (no libreoffice/chromium — but note #103 just put those there deliberately, and a demo desktop that can't browse is the bug #103 fixed).

The gotcha that decides feasibility: without the pin, a netinstall target fetches from cache.nixos.org for stock nixpkgs paths — but Nomarchy's own derivations are in no binary cache, so they would build from source on the user's machine during install. That is the same failure tools/vm/gap-analysis.py exists to diagnose (and #113 is a live instance of). So this item probably depends on a public binary cache (cachix) for the flake's own outputs, or it trades an 8 GiB download for a 40-minute install. Establish that before building the target.

Pass = a second, documented ISO target that is substantially smaller (state the measured number, both ISOs built from one tree), installs successfully with a network in a QEMU run, says clearly at boot that it needs one, and leaves the offline ISO's behaviour untouched (checks.* for the offline path stay green).

LATER

• DPMS when docked (revisit #127): today we skip display blanking while any laptop internal is present-but-disabled (dock/clamshell), so idle only locks. That avoids blanking the sole external and the brick where wake/TTY failed (2026-07-15). Revisit when we want monitor power-save on dock again: re-enable DPMS-off for that mode only if nomarchy-display-wake (or better) reliably restores the external and undock-while-black restores eDP on the AMD dock setup — without depending on SSH. Until then, leave the skip in modules/home/idle.nix.
• Wallpapers artifact split (ROADMAP § Faster switches — decided, deferred): pinned Nomarchy-wallpapers input so a state write stops re-copying 86 MB. Follow-on: pre-built theme variants if switches are still slow after.
• Installer round 2 (ROADMAP § Installer): multi-disk BTRFS RAID, impermanence, BIOS/legacy boot.
• Boot-from-snapshot: a systemd-boot equivalent of grub-btrfs.
• MIPI/IPU software-ISP camera support (no-UVC machines).
• NixOS release bump → v2 [human]: deliberate, hand-edited, never automated; the previous attempt was discarded (2026-06-22) over a Hyprland OOM blocker — see MEMORY.md before retrying.

FUTURE (decided deferred — not the agent queue head)

Work we intend someday but explicitly not NEXT. Agents do not pick these unless Bernardo promotes one into NEXT/NOW.

20. KVM runner → VM suite in CI [human]

Status (2026-07-10): keep eval-only CI on the current Gitea stack (act_runner in docker-compose on the 4c/4 GB IONOS VPS). Nested KVM + RAM headroom on that host are a poor fit next to Gitea; full checks.* VMs stay local / promotion-time until a separate KVM-capable machine exists.

When ready: register a second runner (host-mode nix + /dev/kvm, label nix-kvm — not the existing docker eval runner), then uncomment the vm-checks job in .gitea/workflows/check.yml (runs-on: nix-kvm, nix flake check + toplevel/HM builds). Do not enable the job until that label is online (Gitea queues forever otherwise).

Formatter — adopt later [human]

Intent: add a Nix formatter (likely nixfmt-rfc-style) in a dedicated pass: reformat the tree once, document in CONVENTIONS, optional CI check. Not the queue head — no drive-by reformats until that pass.

PROPOSED (agent suggestions — await human triage)

Agents: append here with a one-paragraph pitch (what/why/cost). Do not implement. Bernardo moves accepted items into a tier.

Open work only. Shipped exam/A–C items (#47–#63, #14, #52 theme high-ROI, etc.) live in the journal + ROADMAP — not here.

Product / day-2

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.

• NVIDIA first-class options — deferred past v1 (Bernardo 2026-07-10). Keep #59 commented install guidance; no nomarchy.hardware.nvidia.* until a hybrid maintainer + queue.

• Post-install hardware hints (VISION § B) — After the general “you're set” card (#81), optionally fire one additional self-gated notify when the machine actually has the hardware: (a) fwupdmgr on PATH → “System › Firmware to check LVFS updates”; (b) fprintd-list on PATH → “System › Fingerprint to enroll”. One-shot markers in settings.* (same in-checkout discipline as firstBootShown); never a permanent MOTD nag. Cost: small — extend nomarchy-first-boot or a sibling oneshot + checks.first-boot fixture. Control-center / MOTD already mention these; the gap is the silent first graphical session for people who never open those.

(#80–#83 + #85–#88 shipped 2026-07-11. Theme A day-2 + neon-glass finish shipped — VISION ✓. Dock/hibernate V3 → HARDWARE-QUEUE. Parallel fingerprint-or-password shipped 2026-07-12 (Bernardo promoted it live; fingerprint.parallel, pam-fprint-grosshack) — reader V3 → HARDWARE-QUEUE.)

v1.0 pointer

See VISION. Open PROPOSED: post-install hardware hints; NVIDIA deferred past v1; IR portal (b)/(c) need T14s (HARDWARE-QUEUE § T14s). Standing calls: browser = Chromium; power = PPD.

Decisions [human]

Open calls only Bernardo can make; agents add options/evidence but never decide. Resolved entries stay for history; agents treat them as closed.

Resolved (2026-07-10)

• Docs site vs Markdown-in-repo — markdown in-repo for now (docs/, README). A rendered docs site is FUTURE if wanted.
• Default browser — ship Chromium in templates/downstream/home.nix; mime → chromium-browser.desktop. Opt out: delete the line / override mime.
• Default power backend — keep PPD (nomarchy.system.power.backend default). TLP remains the one-line opt-in. Rationale: stability + live profile API for menu/Waybar; Omarchy’s TLP experiment reverted.

Resolved (2026-07-10, more)

• Formatter adoption — yes, but not now. Tracked as FUTURE (below). Nix-source style only (nixfmt-rfc-style or similar); one bulk reformat + CI/check when promoted. Until then: hand-aligned style per CONVENTIONS.

• Hibernation — want by default (product intent). Needs a disk-backed swap (file or partition) sized for resume; not zram alone. Shipped as #76; V3 power-cycle PASSED on TuringMachine 2026-07-12 (ROADMAP § Hibernation + zram by default).

Resolved (2026-07-10, #76 design)

• Swap sizing — exactly RAM (installer default, unchanged). Hibernate image ≤ RAM; zram takes day-to-day paging. swapSize=0 stays no-swap.
• Migration — docs runbook (docs/MIGRATION.md), not a tool.
• No-swap Hibernate — keep the menu row; notify on failure.
