• 2026-09-14 the workstation outage: upstream commit 49afdfe ("Noctalia theme migration") committed config.kdl with include "noctalia.kdl" but noctalia.kdl is a per-host GENERATED file, never in the repo; the same pull set ghostty theme = noctalia and alacritty import = themes/noctalia.toml, both also template-generated and absent here. Niri 26.04 does NOT exit on a config error — it logs "error parsing" and boots with DEFAULT config, producing a half-dead desktop (no keybinds/rules/autostart shell, default output placement). noctalia msg templates-apply answers "ok" but is a NO-OP on noctalia 5.0.1 (opt-in schema mismatch). Working fix (offline, no session restart needed): noctalia theme --theme-json ~/.config/noctalia/colors.json --render "builtin template:output" for each: templates/niri/niri.kdl → ~/.config/niri/noctalia.kdl (plain host-local file, NOT a repo symlink), templates/ghostty/ghostty → ~/.config/ghostty/themes/noctalia, templates/alacritty/alacritty.toml → ~/.config/alacritty/themes/noctalia.toml. Tokens resolve fully from the 16-key colors.json (primary_container etc. are derived). Verify: niri validate rc0; fresh login loads full config (journal "loaded config" + custom output placement). Also verified: kill -USR1 was NOT the cause of the session ending that night — journal showed a fresh niri-session login; don't accept blame for user-initiated logouts.
• On this host's niri build, niri msg do reload-config is rejected ("unrecognized subcommand 'do'") — verified 2026-09-10 during the noctalia unification deploy. The working config-reload path is kill -USR1 $(pidof niri) (SIGUSR1 to the niri process); verified on both fleet hosts (the workstation pid via /proc, blankpad over ssh). Future keybind/config deploys that need live reload must use the SIGUSR1 path, not niri msg do.
• Noctalia fleet architecture UNIFIED 2026-09-10: both the workstation and blankpad now run bare noctalia (v5 native, package noctalia 5.0.1-1.1) as the desktop shell, launched via niri spawn-at-startup "noctalia" from repo autostart.kdl. The v4 Quickshell-hosted architecture (qs -c noctalia-shell, JSON settings.json) is retired on the workstation; qs host process killed and replaced live by a transient systemd-run unit (noctalia-live) that hands off to autostart at next login — single-instance guard in the binary makes overlap safe. Live config layer on both hosts = TOML only: hand-edit ~/.config/noctalia/config.toml; runtime state ~/.local/state/noctalia/settings.toml loads last and overrides same keys (never hand-edit). Verified mechanics: noctalia msg resolves the running instance via D-Bus session bus, so it works from systemd user-unit context (systemd-run --user --pipe --wait) even though niri's own environ lacks WAYLAND_DISPLAY; spawn-at-startup children do receive a working display connection. Lock keybinds/swayidle unified to noctalia msg session lock; verified verb grammar includes panel-toggle {launcher,session,control-center,...}, volume-up/down/mute, mic-mute, media next/previous/playPause (graceful no-op rc 0 with no active player), brightness-up/down. Wallpapers: wallpaper-next/wallpaper-get confirm rotation draws from the configured [wallpaper] directory on both hosts; current wallpaper stays on the built-in default asset until first rotation after config-reload. Leftover dead packages on the workstation (noctalia-shell 4.7.7, noctalia-qs fork) are inert — removal is optional cleanup, zero dependents post-flip.
• Divergence explained (as of 2026-09-10): the workstation and blankpad both show noctalia 5.0.1-1.1 but run different live architectures because each host's autostart froze at its adoption-era architecture and package upgrades never rewrote autostart commands. Fossil record from pacman install dates: noctalia-shell 4.7.7-3 installed on the workstation Jul 3 (v4 Quickshell-hosted architecture, JSON config; module files owned at /etc/xdg/quickshell/noctalia-shell/, launched via qs -c noctalia-shell from base niri package autostart.kdl); noctalia-qs 0.0.12-2 (Quickshell fork hosting the shell) installed Aug 24; v5-era noctalia package landed Sep 6 as a parallel package owning ONLY /usr/bin/noctalia + desktop file + README — CLI/client surface, no shell module. blankpad was provisioned fresh Sep 9 entirely from CachyOS repo packaging (noctalia 5.0.1-1.1 + vanilla quickshell 0.3.1-1.1 + cachyos-niri-noctalia 1.4.0-1; no v4-era packages exist in that repo set), so its zz-blankpad override autostart launches bare noctalia (native v5, TOML config). Consequence: settings.json is genuinely the live config on the workstation (v4 code), while blankpad runs true v5 with TOML state at ~/.config/noctalia/config.toml + ~/.local/state/noctalia/settings.toml. Unification candidate when approved: flip both to noctalia as single entrypoint, but verify first that the v5 packaging on the workstation ships the shell module (current -Ql evidence says CLI-only) — a unified flip likely requires installing the full v5 package set on the workstation first. Diagnostic recipe for this class of question: query pacman install dates + package ownership (pacman -Qi/-Ql/-Qo, pgrep -af) to reconstruct which architecture each host actually runs rather than trusting version labels.
• Noctalia shell runtime split on the fleet (as of 2026-09): both the workstation and blankpad install noctalia 5.0.1-1.1 (-dirty = git build), but launch differently — the workstation hosts it via qs -c noctalia-shell (Quickshell host; reads JSON-era config ~/.config/noctalia/settings.json), blankpad runs the bare v5 binary (reads hand-edit ~/.config/noctalia/config.toml, runtime state written to ~/.local/state/noctalia/settings.toml which overrides declarative values last). Lock chain on both hosts: primary qs -c noctalia-shell ipc call lockScreen lock, fallback noctalia msg session lock|suspend|lock-and-suspend|logout|reboot|shutdown. Quirk: noctalia msg ... from a non-session context (ssh command exec) always answers "noctalia is not running" even when the shell runs — detection needs session-scoped state absent in sshd-spawned shells; DBUS_SESSION_BUS_ADDRESS override does NOT fix it. Correct remote procedure: write config files directly (they hot-reload or apply at next start); never treat the msg failure over ssh as evidence the shell is dead. Wallpaper dir default when unconfigured = XDG Pictures ($HOME/Pictures) via user-dirs.dirs; explicit [wallpaper] directory key overrides it — blankpad was seeded with directory = /home/blank/.local/share/noctalia/wallpapers (repo-tracked symlink target).
• blank@blankpad (CachyOS, Arch-like) deployment COMPLETED 2026-09-09 (supersedes earlier "pending action awaiting user go-ahead" note): full-replica rsync of /home/dank/.omp/ → /home/blank/.omp/ (.git included; push to Gitea NOT required for this transport) followed by deploy.sh sync on blankpad. SSH was initially blocked there by firewall default-drop (timeout, not refuse) and opened only after the user started sshd locally — expect that blocker pattern again for new fleet hosts. Host facts verified at deploy time: login shell fish; niri runs as niri --session reading the repo-symlinked config.kdl; installed binaries include noctalia CLI (its keybinds override package uses noctalia msg ..., NOT canonical qs -c noctalia-shell ipc call), alacritty, firefox, nautilus, fish, zsh, shelly-notifications; MISSING: qs/quickshell, ghostty, gnome-calculator — canonical keybinds relying on those are silent no-ops if deployed there. ~/.p10k.zsh on blankpad is an inert repo symlink until powerlevel10k-zsh is installed and sourced. zz-blankpad override package (display/keybinds/misc/rules/autostart/.zshrc) is tracked in the repo; deploy.sh's target derivation must strip the nested base-package segment for zz-* packages or overrides land on phantom paths like $HOME/niri/.config/...
• blankpad is a fleet machine reached only as blank@blankpad.local (mDNS FQDN; bare hostname does not resolve from the workstation; 192.168.0.83). As of 2026-09-09 it runs the command-center deployment at /home/blank/.omp with host-specific divergence preserved as tracked override package dotfiles/zz-blankpad/: its own display.kdl output layout (not the workstation's DP/eDP rig), autostart/keybinds targeting the bare noctalia CLI instead of qs -c noctalia-shell ipc call, misc.kdl without renderD129, rules.kdl without the Noctalia floating-window rule, and blank's own minimal .zshrc. Its login shell is fish. Initial blocker (port 22 drop-not-refuse = sshd down or firewall default-drop) was fixed same day by user locally; if SSH drops again on blankpad, suspect firewall default-drop first, not auth.
• blankpad (user blank) is fleet member at 192.168.0.83, reachable ONLY via mDNS FQDN blankpad.local — bare hostname does not resolve from the workstation. As of 2026-09-09 its SSH was unreachable from the LAN segment: ping fine (~1 ms, wired) but TCP 22 and alt ports (2222/8022/22222/10022) all TIMEOUT = firewall default-drop or sshd down; drop-not-refuse distinguishes this from sshd-listening-but-auth-failing. Pending action awaiting user go-ahead: deploy command-center to blank@blankpad via full-replica rsync of /home/dank/.omp/ (incl .git so core.hooksPath stays armed pre-push) → deploy.sh --check review → sync; transport deliberately chosen over clone-from-Gitea because main was 6 commits ahead of origin/main and push is reserved as a user-only trigger. Note: origin remote on the workstation embeds the Gitea token in plaintext URL — keep it off other machines' .git/config by using rsync as transport. (context: User asked to set up the dotfiles/command-center deployment on blank@blankpad with a password credential; SSH entry point unreachable from this segment, so work was staged and handed back with exact unblock steps (systemctl enable --now sshd + firewalld internal-zone ssh service).)
• The FLM (FastFlowLM) service on Dankclaw (gemma4-it:e4b, port 7771) only supports PNG and JPEG/JPG image formats. WebP images are rejected with "Unsupported image format, skipping this image." The data URL formats it expects are data:image/png;base64, data:image/jpeg;base64, and data:image/jpg;base64. To use WebP screenshots with the NPU, convert them to PNG first. Verified 2026-08-30: a WebP screenshot (1024x576, 71K) was rejected while the same content as PNG was correctly identified by the vision model. (context: Dankclaw NPU (FLM, gemma4-it:e4b, port 7771) — image format support investigation)
• When configuring dankclaw-npu (FLM NPU endpoint on port 7771) in models.json, the model entry must include a thinkingLevelMap field. The other two providers (dankserver, dankclaw) have it; if absent, schema validation fails. Pattern: {"thinkingLevelMap": {"max": "xhigh"}}. Also verify gemma4-it:e4b model ID is registered and .xclbin kernel symlink exists under /home/dank/.config/flm/xclbins/. (context: Dankclaw NPU endpoint (dankclaw-npu provider, port 7771) had a schema error because gemma4-it:e4b was missing thinkingLevelMap. Fixed by adding it to both models.json and models.yml. The FLM NPU serves 34 models in its registry; gemma4-it:e4b is the currently wired model.)
• Dankclaw NPU serves 34 FLM (FastFlowLM) models on port 7771. Only one is wired in models.json (gemma4-it:e4b) but all 34 are registered and available via per-request model routing without restart. Known behavior: single-lane NPU queues FIFO, per-request model switch costs ~7–11s wall for 4B-class reload. Common pitfall: some registered tags fail if .xclbin kernel pack symlink is missing under /home/dank/.config/flm/xclbins/ (fix: ln -s /opt/fastflowlm/share/flm/xclbins/PackName). Registry probe: curl http://192.168.0.143:7771/v1/models.
• Frank's cursor size is 36 (up from default 24) on the workstation running niri/Wayland. Applied via three channels: gsettings org.gnome.desktop.interface cursor-size=36 (primary), GTK settings.ini gtk-cursor-theme-size=36 (fallback), XCURSOR_SIZE=36 in ~/.profile (sessions). Cursor theme: capitaine-cursors. (context: the workstation workstation — Frank requested a bigger mouse pointer; set to 36 across gsettings, GTK config, and environment)
• Frank's default browser is Firefox (firefox.desktop), set via xdg-settings on the workstation (niri/Wayland). Previously was Chromium. Changes persist across reboots. (context: the workstation workstation — Frank changed default from Chromium to Firefox via xdg-settings set default-web-browser firefox.desktop)
• the workstation (RTX 4070 Laptop, nvidia-open 610.57.04, kernel 7.2.0-1-cachyos, DynamicPowerManagement=2) suffers the known 610.x NVKMS DIFR-prefetch deadlock: nvidia-modeset/kthread_q livelocks in DifrPrefetchEventDeferredWork→nvWriteGpEntry holding the NVKMS API semaphore; any compositor (niri) atomic commit then wedges in D-state in ApplyModeSetConfig/nvkms_ioctl_from_kapi_try_pmlock. Symptoms: GUI frozen, no VT switch, SSH alive, nvidia-smi still answers (GPU idle P8, no Xid). Trigger: display-idle then flip/modeset. Unrecoverable in place — reboot via systemctl reboot --force --force. Candidate mitigations: NVreg_RegistryDwords="RMDisableDIFR=1" (one upstream report says ineffective) and DynamicPowerManagement=0. Bug class spans 595.71–610.57 upstream. (context: 2026-08-30 GUI lockup diagnosis on the workstation; user suspected nvidia modesetter, confirmed via hung-task stacks. Pending user decision on writing modprobe mitigation.)
• When downloading large model shards (40GB) to dankclaw via SSH: 1. NEVER run rm on partial downloads — always clean up BEFORE starting the first download 2. Ensure only ONE wget process per file — if you see duplicate wget PIDs killing them with kill -9 before restarting, or use fuser to verify exclusivity 3. Use wget -c (continue) to resume partial downloads — SSH connections often drop mid-download on large files (~300s timeout) 4. Download sequentially (not in parallel) when using background task agents that may spawn duplicate processes, or coordinate downloads through a single agent session 5. Verify each file's size against expected values after download completes
• kingjones777's Qwen3.8-Flash-Next ROCmFP4 builds for Strix Halo (gfx1151) have three tiers: FAST (~88 GiB), STRIX_LEAN (~98.5 GiB, 3-shard), STRIX (~113.5 GiB). All are text-only — no vision tower, no mmproj, no fused MTP draft head. Uses TYPE_100/TYPE_101 ROCmFP4 tensor types (general.file_type=106), requires patched llama.cpp PR #27742 from ROCmFPX fork. STRIX_LEAN carries a 35.76 GiB PLE n-gram table streamed off SSD at runtime; ~63 GiB GTT for non-PLE weights, ~75 GiB at full 262K context. Uncensored variants exist from orcarouter but only for Qwen3.8-27B (not Flash-Next), and in non-ROCmFP4 format. (context: User requested kingjones777/Qwen3.8-Flash-Next-Uncensored-ROCmFP4-STRIX_LEAN-GGUF for frank-default-large on dankclaw. Search revealed the repo doesn't exist; only the base STRIX_LEAN tier is available, and it's text-only with no MTP.)
• Model provider config is SINGLE-SOURCE: ~/.omp/agent/models.yml (OMP is the primary harness). The pi-era dual-copy convention (~/.pi/agent/models.json as source of truth + generated YAML import) is retired — there is no second file to keep in sync. Validate edits with a YAML parse. Label strings are NOT cached in ~/.omp/agent/models.db (model_cache table), so no cache flush is needed after label edits — new labels apply on the next config read.
