epic: 1.0 readiness #94

Summary

Hardware validation, unknown-controller mapping, device selection, security hardening, staging cleanup, UI automation, signing, package size and key rotation.

Motivation

The spec forbids announcing 1.0 while essential journeys are unvalidated on real hardware.

• feat: add a mapping wizard for controllers without a known profile #79 — feat: add a mapping wizard for controllers without a known profile (priority: high)
• feat: switch the active controller explicitly and diagnose duplicate devices #80 — feat: switch the active controller explicitly and diagnose duplicate devices (priority: medium)
• security: handle-based destination checks against junction races #81 — security: handle-based destination checks against junction races (priority: medium)
• feat: clean up leftover staging folders from interrupted operations #82 — feat: clean up leftover staging folders from interrupted operations (priority: medium)
• test: add WinUI automation tests for focus, dialogs and the virtual keyboard #83 — test: add WinUI automation tests for focus, dialogs and the virtual keyboard (priority: medium)
• chore: set up code signing for releases #84 — chore: set up code signing for releases (priority: medium)
• enhancement: reduce package size by trimming unused Windows App SDK components #85 — enhancement: reduce package size by trimming unused Windows App SDK components (priority: medium)
• security: support update-signing key rotation #86 — security: support update-signing key rotation (priority: low)

Dependencies

• feat: detect the active controller family (Xbox, PlayStation, Nintendo, generic) #32 (M2) → test: validate the controller matrix on real hardware #78, feat: add a mapping wizard for controllers without a known profile #79

Acceptance Criteria

• Every issue in the scope is closed or explicitly moved out of the milestone with a reason.
• PROGRESS.md, both changelogs and the relevant docs reflect what shipped.

Tracking issue for milestone 9 · 1.0 Readiness. Priority: high.
