# 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`](../docs/VISION.md); design history
in [`docs/ROADMAP.md`](../docs/ROADMAP.md); map in
[`docs/README.md`](../docs/README.md) and [`agent/README.md`](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.

## NOW

### 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**.
