+# Unified input configuration and routing proposal
+
+Status: implemented locally for device evaluation; not published or approved by maintainers.
+Prepared on 2026-10-23 against `ac0909ea`.
+Related source snapshots: PR #1202 at `42db788f`, PR #1305 at `76fc9b31`.
+
+## Problem and scope
+
+DroidDeck has useful input paths whose configuration and lifecycle rules are
+spread across several components. Desktop users need configurable physical
+controller bindings. Dual-screen users also need to arrange and configure lower
+screen controls without giving up Steam Deck trackpads or Steam Input layouts.
+
+Provide one configuration model and reusable action handling while preserving
+the existing low-latency transports and Steam's ownership of Steam-managed
+bindings. A common model does not require all input to cross a new queue, UI
+thread, generic event bus, or virtual device.
+
+The implementation has two editable built-in profiles, Game and
+Desktop. Named profile creation, per-application selection, and profile
+import/export are future work; the stored model must allow them without changing
+the routing contract.
+
+## Existing paths to preserve
+
+| Source | Current path | Meaning |
+| --- | --- | --- |
+| Android physical pad | `PadBridge` -> `FakeInputWriter` | Gamepad buttons, axes, player slots |
+| Built-in screen pad, including the lower-screen Gamepad tab | `PadBridge.applyTouch` -> `FakeInputWriter` | Virtual gamepad input |
+| Lower-screen Deck trackpads and back grips | `DeckControlsPanel` -> `DeckControls` -> `FakeInputWriter.writeDeckControls` | Touch coordinates, contact, click/pressure, L4/L5/R4/R5 |
+| Steam touch overlay | `SteamTouchControls` -> `SteamTouchDevice` -> Steam | Steam Mobile Touch reports, with Steam-owned bindings and action sets |
+| Desktop trackpad and keyboard | Existing gesture/keyboard handlers -> compositor | Direct guest mouse and keyboard input |
+| Steam Controller BLE and proposed native DualSense | Driver-specific report paths | Input can bypass Android `KeyEvent` dispatch |
+
+Deck trackpads must not be reduced to mouse deltas or a pair of ordinary joystick
+axes. Their contact, coordinates, click state and pressure are meaningful to
+Steam. Likewise, Steam Mobile Touch is a distinct protocol, not another spelling
+of an Xbox pad.
+
+See [Steam touch controls](steam-touch-controls.md) for the current integration,
+including Steam-owned layouts, action sets and cloud configuration.
+
+## Separate bindings, screen layout, and device calibration
+
+The proposed model has three independent parts:
+
+- **Binding profile:** logical input sources and their actions, with Game and
+  Desktop defaults and user overrides.
+- **Surface layout:** which controls appear on the primary or secondary control
+  surface, their positions, sizes and presentation. A layout references bindings
+  or Steam-managed controls; it does not copy Steam's action-set definitions.
+- **Device configuration:** hardware identification, axis normalization,
+  calibration and capabilities. This is separate from a user's desktop layout.
+
+Use logical surface roles rather than persistent Android display IDs. Controls
+need stable IDs independent of their location. Moving a control to the lower
+screen must not change its action or create a new guest gamepad. The existing
+player-slot and device identities remain authoritative.
+
+A Game profile can use the lower screen for two Deck trackpads and back grips,
+plus selected DroidDeck actions. A Desktop profile can put a mouse trackpad and
+keyboard there while mapping the physical sticks to arrow keys, scrolling or
+other actions. Connecting a second display must not silently rewrite physical
+controller bindings.
+
+The model should support reusable lower-screen layouts later. Initially expose
+existing layouts and a bounded set of configurable controls; a complete freeform
+multi-display editor is a separate deliverable.
+
+## Steam Input ownership
+
+Each binding explicitly selects an execution path:
+
+1. **Native/Steam-managed:** send the existing controller or touch report.
+   Steam remains responsible for game bindings, action sets, layers and its
+   touch/radial menus. DroidDeck shows an appropriate entry into Steam's editor.
+2. **DroidDeck-managed:** execute a guest key combination, mouse action or
+   application action through the existing output functions. The consumed
+   control is excluded from the normal controller output.
+3. **Disabled:** intentionally produce no action.
+
+Steam-managed and DroidDeck-managed controls can coexist on one surface. One
+activation must have one semantic owner, so a local keyboard shortcut does not
+also produce the original controller button. Gamepad-to-gamepad remaps remain
+explicit preprocessing before the normal game/Steam path, rather than a second
+independent action sent alongside it.
+
+Steam Input already supports extensive binding and touch-menu behavior. This
+proposal concentrates DroidDeck's work on Android surfaces, app shortcuts,
+desktop/non-Steam bindings and consistent lifecycle handling. It does not propose
+reimplementing Steam's configuration engine or importing its profiles into a
+second authoritative store.
+
+Preserve raw-report fields and output/feedback channels not affected by a local
+binding, including motion and haptics. Driver-specific adapters must participate
+before publishing consumed controls; an Activity-only interceptor cannot cover
+raw HID devices.
+
+## Configuration and runtime model
+
+Responsibilities:
+
+| Component | Responsibility |
+| --- | --- |
+| `InputProfile` | Version, stable ID, default role, bindings and surface-layout references |
+| `SurfaceLayout` | Stable control IDs, display role, geometry and appearance |
+| `InputBinding` | Source selector, activation rule, action and execution owner |
+| Source adapters | Preserve device identity, normalize inputs and expose capabilities |
+| Compiled binding plan | Pre-resolved routes for one active profile and its devices |
+| Action executor/output ownership | Execute existing outputs and track held contributions |
+
+Buttons and axis directions can produce keys, key combinations, mouse buttons,
+gamepad buttons or app actions. Sticks can retain their gamepad role or produce
+pointer velocity, scrolling or keyboard directions. Analog triggers need distinct
+press/release thresholds when used as buttons. Capability-aware controls should
+explain why an unavailable action cannot run, rather than silently substituting
+another behavior.
+
+The same action picker is reused for physical and local screen controls. Screen
+geometry stays outside binding execution. Steam-managed widgets retain their
+native configuration and protocol adapters.
+
+Configuration is loaded, validated and compiled when it changes. Dispatch uses
+an immutable plan snapshot and preallocated per-source state. JSON decoding,
+preference reads, disk writes and layout traversal do not belong in event dispatch.
+Use stable symbolic control/action identifiers in storage; transient Android
+device IDs are runtime keys, not portable profile identifiers.
+
+Profile selection defaults to the session's mode, with an explicit session
+override. Desktop mode can contain a game, so it is not sufficient evidence for
+automatic keyboard/mouse interception. An optional profile-switch action uses
+the same app-action mechanism as menus and keyboard display.
+
+## Ownership and lifecycle
+
+- Track held keys and mouse buttons by source. Releasing one source must not
+  release a key or button another source still owns.
+- Cancel only a disappearing surface's or disconnected device's contributions;
+  avoid a global release that also clears another screen or controller.
+- Define arbitration for multiple sources targeting the same analog control or
+  Deck touch surface. Retain ownership through a contact; do not let concurrent
+  views overwrite each other's reports or add a second virtual pad implicitly.
+- Changing a binding/profile releases its old outputs before installing the new
+  route. Held controls must return to neutral before triggering a new binding.
+- Menus, keyboard capture, pause, focus loss and device removal have explicit
+  routing rules. Menu navigation retains working confirmation, cancellation and
+  page controls even when those buttons have gameplay bindings.
+- Keep system-reserved Android inputs with the system and retain touchscreen
+  access to reset a problematic controller assignment.
+
+Button chords require a deliberate policy. A dedicated modifier can select a
+chord without delaying unrelated controls. A button that also has a single-press
+action may require deferred dispatch to disambiguate a chord, hold or double tap.
+That delay must be opt-in, visible in configuration and limited to the affected
+binding. Do not buffer all controller presses to support optional chords.
+
+## Latency requirements and verification
+
+The goal is no additional scheduling stage for normal input, not an unmeasured
+claim of zero added latency.
+
+- Identity routes retain the existing direct publication path and report format.
+- Ordinary buttons and touch reports must not wait for drawing, Compose state,
+  a new coroutine, a timer, an event-bus subscriber or another frame.
+- Add no hot-path allocations for ordinary binding lookup. Reuse buffers and
+  keep critical sections short. The current router serializes routing and profile
+  changes under one monitor to keep shared output ownership consistent; hardware
+  traces must establish whether this causes contention before publication.
+- Continuous stick-to-pointer movement needs a clock even when no new stick
+  event arrives. Keep that scheduler limited to the active synthesized movement
+  route; stop it at neutral. It must not schedule ordinary gamepad forwarding.
+- Keep existing synchronization and low-latency flags intact until measurements
+  justify a separate change. Do not weaken shared-memory publication ordering.
+- Send UI updates separately from input publication. Marshaling app-menu work to
+  Android's UI thread must not marshal ordinary controller output with it.
+
+Before publishing the change, record a baseline on Thor with the same build
+configuration, controller mode, display refresh rates and low-latency settings.
+Compare identity forwarding, a local key binding, stick-to-pointer, Deck trackpad
+input and simultaneous upper/lower-screen input under both idle and rendering
+load. Measure p50/p95/p99 dispatch-to-publication time, allocations and contention.
+Use debug-only sampling or buffered tracing; avoid per-event log writes.
+
+Android-to-publication measurements do not measure complete button-to-photon
+latency. Guest receipt and rendered response need separate measurement, with
+clock-domain alignment for cross-process traces or an external high-speed-camera
+test. Record benchmark conditions and uncertainty; establish numerical acceptance
+budgets from the baseline before presenting latency claims in a PR.
+
+Hard acceptance conditions include no new frame/timer wait for identity routes,
+no duplicate or lost press/release transitions, and no degradation of current
+Deck trackpad behavior. Microbenchmarks alone cannot establish those conditions.
+
+## Reuse, migration, and removal
+
+- [#1202](https://github.com/Droid-Deck/DroidDeck/pull/1202): reuse physical capture,
+  device identification and menu-action UI where suitable. Generalize the
+  execution contract beyond Activity `KeyEvent` interception.
+- [#1305](https://github.com/Droid-Deck/DroidDeck/pull/1305): reuse PC-key definitions,
+  key selection and screen-control presentation. Adapt keyboard output to shared
+  ownership; its screen-layout format is not a complete physical-input profile.
+- [#581](https://github.com/Droid-Deck/DroidDeck/pull/581): coordinate device
+  calibration/profile matching, independently of user binding/surface profiles.
+- [#1226](https://github.com/Droid-Deck/DroidDeck/pull/1226): use a shared keyboard
+  action with the appropriate existing host/display, rather than hard-coding a
+  second keyboard implementation.
+- Reuse current guest keyboard/mouse output, `PadBridge`, Deck/Steam touch
+  transports and the existing second-screen presentation lifecycle.
+
+Remove duplicated settings, capture UI and action switches only after their
+replacement preserves saved settings and passes behavior tests. Do not remove
+working device adapters, Steam touch support or native transport code merely to
+make the architecture diagram more uniform. Stage each migration so it can be
+reviewed and reverted independently.
+
+## Implemented local evaluation build
+
+No PR is created yet. Test the complete integrated change on Thor before deciding
+whether to publish it. The intended framing is **Shared input profiles and
+configurable control surfaces**, with links to the desktop requests
+[#860](https://github.com/Droid-Deck/DroidDeck/issues/860) and
+[#1356](https://github.com/Droid-Deck/DroidDeck/issues/1356), the centralization
+discussion in #1202, and the related work above. Those discussions are context,
+not maintainer approval of this implementation.
+
+### Runtime and configuration
+
+- `InputProfile` separates actions and source roles from `InputSurfaceLayout`.
+  `InputProfiles` stores a versioned document and migrates legacy touch mappings
+  and Select-as-Steam into Game once. Editing one role does not edit another.
+- `InputRouter` resolves actions when a profile changes. `PadSource` returns the
+  original `PadState` on the identity path. Other routes reuse their output
+  buffers and consume only the selected control. A key combination presses
+  modifiers first and releases in reverse order. Trigger/direction hysteresis
+  uses separate press and release thresholds.
+- `PadBridge` preserves physical player slots and separately owns each touch
+  surface. Merging uses OR for buttons, maximum trigger values and the strongest
+  complete stick vector. Surface removal cannot release another source's hold.
+- `DeckControls` keeps per-source contacts, coordinates, clicks and pressure.
+  Default native actions retain the existing Deck report. Local trackpad actions
+  use contact-relative deltas, avoiding a jump at first contact.
+- `TritonInputRouter` routes Steam Controller BLE reports before publication. Its
+  identity path returns the original byte array. Other paths preserve packet,
+  timestamp, inertial data, grip-contact bits, report extensions and pressure.
+  This adapter is covered by synthetic report tests; physical BLE testing is
+  still required.
+- `PhysicalInputBindings` captures device identity, keycode and scancode, including
+  controller buttons exposed as keyboard keys. It consumes a configured local
+  action before normal dispatch and keeps releases paired across profile edits.
+  Android volume and system keys remain reserved.
+- `HeldInput` coordinates local mappings with existing guest keyboard, gesture,
+  mouse and second-screen outputs. `InputMotion` schedules only synthesized
+  stick movement/scrolling. Buttons and trackpad deltas publish synchronously;
+  UI commands use the existing main-thread handler.
+- Profile changes, suspension and menu entry release local outputs and require
+  held inputs to return to neutral before activating their new actions.
+
+### User interface
+
+Input profiles are available from Controller setup and the session's Controller
+panel. Auto selects Desktop for a desktop session and Game for other sessions;
+manual selection handles games launched from a desktop without guessing from
+window focus. The editor exposes physical, primary-screen and secondary-screen
+roles, native/remapped gamepad output, local actions and disabled bindings.
+
+Custom controls is an additional second-screen mode. Its editor arranges a
+bounded set of existing `DeckControlsPanel` buttons, sticks, trackpads and grips.
+Layout geometry is independent of bindings and saved per built-in profile.
+Android keyboard input reuses `KeyboardHost`; the existing keyboard/trackpad
+and Deck panel modes remain available. Shared PC-key definitions are taken from
+PR #1305 at `76fc9b31`; capture/identity handling follows PR #1202 at `42db788f`.
+Neither PR is merged wholesale. The superseded touch-only mapping page and
+Select-as-Steam UI toggle are removed after migration.
+
+### Boundaries and deferred work
+
+Steam Mobile Touch retains its Steam-owned action sets, layouts and cloud data;
+its controls are edited in Steam. It does not pass through DroidDeck's local
+remapper. Existing gesture recognition and VR controller handling are retained;
+gestures share output ownership, while the VR-specific input path remains owned
+by VR. Native remaps are limited to compatible controls within the same report
+family. An Android physical key can retain its original behavior or run a local
+action; capture does not synthesize an unrelated hardware device.
+
+Named profile libraries, importing/exporting profiles, per-app switching,
+reusable layout presets, macros, tap/hold/chord activation and a freeform
+multi-display drag editor remain deferred. Key combinations emitted by one
+binding are supported; multi-button activation chords are not implemented.
+Hardware calibration stays in the existing adapters. No native transport,
+Steam haptics path or device driver is replaced.
+
+### Validation and Thor procedure
+
+Before changes, the existing controller/PadMouse/on-screen/second-screen tests
+passed. The integrated suite exercises routing, shared holds, key order,
+hysteresis, neutral gating, profile migration/persistence, raw report preservation,
+existing input paths and the Compose binding/layout editors. See the local
+Gradle test report for exact results.
+
+1. Install the local test APK alongside the signed public app; keep runtime data
+   and baseline configuration available. Do not replace the official signing key.
+2. In a Desktop session, test pointer/scroll, mouse buttons, arrow keys, arbitrary
+   key combinations and captured hardware back buttons. Open and close the drawer
+   and keyboard with controls held; verify every guest release.
+3. Select Game and test Factorio plus Steam UI, first with the default native
+   profile, then with individual bindings changed to local or disabled. Repeat
+   with Xbox 360 and Steam Deck virtual-controller modes.
+4. Exercise keyboard/trackpad, Deck panels and Custom controls on the lower screen.
+   Hold the same output from two sources, remove a surface, change profiles while
+   holding sticks/buttons and reconnect the controller/display.
+5. Enable Input diagnostics, close the editor, generate input under idle and
+   rendering load, then reopen and read p50/p95/p99. Recording is bounded to the
+   most recent 4096 samples and disabled by default. `InputTiming` measures dispatch
+   through existing transport publication, including routing. It does not measure
+   full button-to-photon latency. Use the same instrumentation on a baseline build
+   before making comparative claims.
+6. Record refresh rates, controller/transport mode, build type and low-latency
+   flags. Compare raw identity, local key, pointer and native Deck routes. Use
+   external high-speed video or aligned guest traces for end-to-end measurement.
+
+A passing host test suite does not establish latency on Thor or physical BLE
+compatibility. Those remain explicit release gates before a public PR.
