Second experiment against the connected-but-dark-head stutter (field-proven
on the reporter's box: unplugging his standby HDMI TV removes a metronomic
~4 s double-jolt; DDC/CI is a dead end for TVs — measured on the lab LG, VCP
0xD6 gets no I2C ACK). An Exclusive isolate only removes physical monitors
from the CCD topology; their PnP devnodes stay live, so every standby wake
(auto input scan, Instant-On HPD cycling) still triggers the full Windows
reaction: PnP arrival/removal, CCD re-evaluation, DWM invalidation — the
suspected hiccup mechanism (Apollo #368's Device-Manager-refresh signature).
- New `pnp_disable_monitors` display-policy axis (default off): orthogonal
to presets like game_session/ddc_power_off, surfaced in GET/PUT
/display/settings + the enforced list, carried through the layout
transform.
- windows/monitor_devnode.rs: after the isolate takes, disable exactly the
deactivated monitors' devnodes — CCD target → monitor device path
(DISPLAYCONFIG_TARGET_DEVICE_NAME) → PnP instance id → CM_Disable_DevNode
with CM_DISABLE_PERSIST, so a hot-plug RE-ARRIVAL stays disabled (that
persistence is the whole point). Teardown re-enables BEFORE the CCD
restore (+300 ms re-arrival settle) so restored paths have their monitors
back. Precise selection — co-installed third-party virtual displays are
never touched.
- Crash safety: instance ids journal to <config>/pnp-disabled-monitors.json
before disabling; serve startup re-enables leftovers from a crashed host.
Worst case is documented in the console help (Device Manager re-enable).
- Web console: second Experimental-badged toggle (the DDC block refactored
into a shared ExperimentalToggle), EN/DE strings, preset-switch carry.
Verified: Linux 263 tests + clippy + fmt clean; Windows (RTX box) 220/220 +
clippy clean; web tsc + production build clean; openapi.json regenerated.

The sole-virtual-display stutter investigation's active experiment: when the
Exclusive isolate deactivates a physical monitor, the dark-but-connected head
keeps getting serviced (monitor standby auto-input-scan / DP link churn) at a
seconds-scale cadence — the leading suspect for the periodic double-jolt. A
panel commanded off over DDC/CI (the VESA monitor-control channel in the video
cable) believes it has an owner and, on cooperating firmware, stops probing.
- New `ddc_power_off` display-policy axis (default off): orthogonal to presets
like game_session, stored in display-settings.json, surfaced in GET/PUT
/display/settings + the enforced list, carried through the layout transform.
- windows/ddc.rs: VCP 0xD6 power-mode control via the dxva2 Physical Monitor
API. Deliberately DPMS-off (0x04, DDC stays responsive, signal return wakes)
and never power-button-off (0x05, bricks-until-button on many monitors).
Probe-before-write; every failure is skip-and-log — monitors without DDC/CI,
OSD-disabled, or behind docks/KVMs degrade to a logged no-op.
- Manager wiring: panels commanded off immediately BEFORE the Exclusive CCD
isolate (an HMONITOR — and with it the DDC channel — only exists while the
display is active); teardown wakes them right after the CCD restore, where
returning signal alone already wakes most firmware.
- Web console: an Experimental-badged on/off control on the display card,
applied immediately like the game-session axis and preserved across preset
switches; EN/DE strings incl. the wake-failure escape hatch (press the
monitor's power button once, turn the option off).
Diagnostic value on top of the fix: if this kills a reporter's stutter, the
churn is monitor-firmware-initiated; if only topology=primary/extend does, the
driver services dark heads regardless — the two remaining root-cause classes.
Verified: Linux 258 tests + clippy + fmt clean; Windows (RTX box) 220/220 +
clippy clean; web tsc + production build clean; openapi.json regenerated.

- Favicon: the brand-mark lens SVG at /favicon.svg, linked from the root head.
- Branding: user-facing "punktfunk" → "Punktfunk" (tab title, app_name,
pairing prose, the logo aria-labels/SVG titles) — protocol identifiers
(punktfunk/1, _punktfunk._udp, binary/module names) stay lowercase.
- The display policy auto-saves on every preset pick / field edit with no
signal; mount @unom/ui's sonner Toaster in the root and fire a success toast
from the save funnel's onSuccess (new i18n key, en + de). First toast usage
in the console — errors stay inline as before.
- The stop-session button rendered destructive-red even with nothing to stop:
variant switches to the muted `secondary` while no session is active.

Save named bundles of the display-management policy (the six behavior axes
plus the game-session axis) as custom presets, alongside the built-ins. A
custom preset is data — stored in <config>/display-presets.json — not a Preset
enum variant, so DisplayPolicy::effective() stays pure and the built-in set is
untouched; applying one writes a Custom policy via the existing PUT
/display/settings.
- policy.rs: CustomPreset/CustomPresetInput + load/add/update/delete store
- mgmt.rs: GET/POST /display/presets + PUT/DELETE /display/presets/{id},
surfaced on GET /display/settings
- web console: custom-preset cards with save-as / edit / delete + i18n
- regenerated api/openapi.json; docs

Console polish on the Virtual displays card + shell:
- Topology help now leads with the streamed display's role (Extend/Primary/Exclusive) instead of
the confusing physical-monitor-only framing; notes the headless case. Identity help spells out the
actual behavior (stable per-client identity → the desktop reapplies that client's scaling/resolution
on reconnect) + what Shared / Per-client / Per-client+resolution each do.
- Cap description/help width at max-w-prose so long help text isn't a full-viewport line on large screens.
- Mobile bottom nav: 8 flat tabs were too cramped → 4 pinned tabs + a "More" tab whose sheet holds the
rest (Performance/Logs/Pairing/Settings), "More" highlighted when the active route is in the overflow.
- More breathing room under the "Preset" heading.

Completes the last §6A-era preset. The Linux registry already resolved forever→Pinned (pure
lifecycle machine); the blockers were the Windows manager, the mgmt reject, and the console tag:
- Windows manager: new `MgrState::Pinned { mon }` — the last-released monitor under keep_alive=forever
is kept indefinitely (like Lingering but the linger timer never fires). A reconnect preempts +
recreates it (same as Lingering — a reused IddCx swap-chain is dead), snapshot reports "pinned",
and `force_release` (POST /display/release, the §8 escape hatch) frees a pinned monitor. release()
branches on the new `keep_alive_forever()`; all MgrState matches made exhaustive over Pinned.
- mgmt PUT /display/settings: stop rejecting keep_alive=forever (now honored on both platforms with a
release path). OpenAPI regenerated.
- web: un-disable the gaming-rig preset (DISABLED_PRESETS now empty) — one-click applies.
Linux paths + web/tsc/openapi green; 47 vdisplay tests pass. The Windows manager.rs is #[cfg(windows)]
(not compilable on the Linux dev box) — build-verified + on-glass validation on .173 to follow.

The preset options were raw <button>s — flat, no motion/material — unlike the rest of
the console. They now render as the `interactive` AnimatedCard (motion hover + specular
material, consistent with every other card), keyboard-accessible (role=button + Enter/
Space), with a 2px primary ring for the active one and a proper disabled state for
gaming-rig.

- Every option in the custom form now renders through one `Field` wrapper (label →
control → help at a consistent `space-y-3`), so the label→input gap is roomier and
identical across keep-alive, the button groups, and max-displays — the first field no
longer spaces differently from the rest.
- Reworded the multi-monitor layout help: it now says Auto is side-by-side and Manual
gives a per-display X/Y editor "in the Live displays section below once two or more are
streaming" — instead of pointing at an "arrangement table" that isn't visible until
clients connect.

Two UX fixes on the Virtual displays Configuration card:
- Keep-alive is no longer implicitly "on" by typing in the seconds field. It's an
explicit two-button toggle — **Off** (tear down at disconnect) vs. **Keep for** [N]
seconds — and the seconds input only appears when "Keep for" is selected. The
duration is remembered across toggles, and the help text explains both modes.
- Opened up the cramped custom form: the fields container is `space-y-6` with more
padding (`p-5`, rounded-lg), each option group is `space-y-2.5`, and the Save button
sits below a divider — so it reads as sections with room instead of a pressed stack.

The Host page was crowded (identity, codecs, ports, GPU, displays, compositors) and the
virtual-display config surface is large enough to warrant its own home.
- New **Virtual displays** nav section: `/displays` route + `sections/Displays` (moved
DisplayCard out of `sections/Host`), a `MonitorPlay` sidebar entry after Host, and
`nav_displays` i18n. Removed the displays card from the Host page/view.
- On its own page the card splits into two: **Configuration** (presets + custom axes) and
**Live displays** (the live list + arrangement table) — room to breathe.
- Presets now render in a max-2-column grid (`sm:grid-cols-2`) with larger padding, a bigger
section heading + preset titles (text-base semibold), roomier spacing, and bottom-aligned
"what it sets" badges so the cards line up.
web tsc + vite build + biome-lint green; deployed + verified on the Mutter box (.21).
