feat(doctor): #77 hibernate/sleep section (VISION § C)

nomarchy-doctor gains a read-only hibernate/sleep section (the highest-ROI
Day-2 gap, a natural #76 follow-on): resume device on the kernel cmdline
(+ resume_offset for a swapfile), disk swap >= RAM, zram active, and any
suspend/hibernate error in the previous boot's kernel log. Self-gates
(skip on swap=0) and emits only ok/warn/skip, so it never fails the sheet.
Adds `hibernate` to the checks.doctor probe list so the row is asserted.

Fixes a set -euo pipefail hazard the first VM run caught (exit 1, no
verdict): a no-match grep inside $(...) and a `cond && action` both abort
under set -e — now guarded with || true / || echo 0 / if. Recorded in
MEMORY as a reusable gotcha for writeShellScriptBin scripts.

Verification: V2 PASS — checks.doctor VM test green (fresh build, exit 0;
asserts the hibernate row renders, healthy run stays 0). V1 — ran on real
LUKS+@swap hardware: all three ok rows render (resume set, swap 34G >= RAM,
zram 16G) and the sheet reaches its verdict. V0 bash -n + flake check.

Raw Blame History

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.

NOW

(empty — NEXT's top item is the queue head)

76. Hibernation default — all agent work shipped `[blocked:hw]`

Hibernation + zram on by default (product intent, Bernardo 2026-07-10). All V0/V1/V2 slices done (2026-07-10); only the V3 check remains — on a machine actually running Nomarchy (the dev box runs Bernardo's own NixOS, not Nomarchy, so it can't close it). Steps in HARDWARE-QUEUE. Design record in ROADMAP § Hibernation + zram by default. Shipped:

zram default (modules/nixos/oom.nix, zstd/50%/prio 100) — checks.zram-swap.
Installer/template already default new installs to a RAM-sized encrypted @swap swapfile + resume_offset wiring; swapSize=0 = no-swap opt-out.
docs/MIGRATION.md enable-hibernation runbook (existing machines).
rofi.nix Power → Hibernate: kept unconditional, notifies on failure.
checks.hibernate VM test (V2 PASS) — hibernate→resume→crash round-trip; zram (prio 100) doesn't swallow the image, disk swap carries it.

V3 remaining: real hibernate→resume on the LUKS+@swap swapfile+offset layout (QEMU can't feed a boot-time offset / drive LUKS-initrd) + the no-swap notify in a real session. Steps queued in HARDWARE-QUEUE. Close #76 on PASS.

LATER

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.
Night-light geo mode: lat/long auto sunset/sunrise (means wlsunset).
MIPI/IPU software-ISP camera support (no-UVC machines).
VPN exit-node richer display (country/city) (optional).
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 (NOW#3 should also soften that blocker class).

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.

Hibernation + zram

Promoted → NEXT #76 (2026-07-10).

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

(Doctor hibernate/sleep section → promoted to NEXT #77 2026-07-10.)

(Battery charge-limit instant → shipped 2026-07-10; V3 PASS Latitude 5310: Custom charge type + live menu + unplug re-apply.)

(Portal/Flatpak IR camera → #71 docs (a); (b)/(c) still need T14s.)

(Post-install hardware hints residual → #73.)

(Look & Feel submenu → already shipped (Theme / wallpaper / night light); 2026-07-10: Reset wallpaper (auto) row; root stays six.)

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.

Installer / template

(Installer ↔ template SoT CI → #72; V2 install → #75.) (Installer chown flake dir → #65.) (MIGRATION.md snapshot layout → #64.) (Unattended-install test matrix → #74.) (Friendlier mkFlake theme-state errors → #66.)

Theme polish

Auto time-of-day theme pair (VISION § D) [big] — no scheduled light/dark theme switch exists today (only night-light gamma via hyprsunset
- wallpaper bg auto). Let a user pair two shipped themes (e.g. summer-day ↔ summer-night) and switch on a schedule/sunset through the existing engine — a systemd timer running nomarchy-theme-sync apply <slug> — staying one theme engine (GOALS: no second pipeline). Split before starting: (a) state schema for the pair + schedule, (b) the timer/ hook, (c) menu surface. Cost: multi-slice; verify each apply still bakes one clean generation. (Verified 2026-07-10: no time-of-day/auto-theme scheduler in the tree.)

(#52 residual ANSI → #68 ✓.) (Fidelity / hierarchy nits → #67 ✓.) (Import pipeline hierarchy → #70 ✓.) (audit-theme-design identity exemptions → #69 ✓.) (summer-day/night pair polish + status CSS + preview recapture → shipped 2026-07-10: JSON SoT, status states, theme-shot previews for executive-slate + neon-glass.)

(Identity taste retunes + hand btop.theme for white/vantablack/lumon/ hackerman/matte-black/miasma/neon-glass/boreal/executive-slate → shipped 2026-07-10.)

Docs / narrative

Omarchy migrant one-pager (VISION § F) — no Omarchy→Nomarchy guide exists (MIGRATION.md is NixOS→Nomarchy; RECOVERY is recovery). Omarchy is the closest sibling and the likeliest source of new users. A short docs/ page mapping the deltas: keybindings, the theme system (nomarchy-theme-sync vs Omarchy's), the install path (ISO vs Arch script), and what feels the same (Hyprland/Waybar). Docs-only, low-risk, adoption-facing. Cost: small. (Verified 2026-07-10: no "omarchy" mentions in docs beyond VISION's idea.)

v1.0 pointer

See VISION. Doctor hibernate section promoted → NEXT #77. Open PROPOSED: Omarchy migrant doc (§F); auto time-of-day theme pair (§D, big); NVIDIA wrappers deferred past v1; IR portal (b)/(c) hardware. Browser default = 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. Implementation is a future/NEXT item when designed (installer + resume device + encrypted-root story).

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.
