* docs(performance): inventory the zoneless change-detection migration Plan item C6 step 2. docs/architecture/zoneless-migration.md lists the 66 production files (67 components) that still set ChangeDetectionStrategy.Eager, the ten places where a template-read plain field is written outside an Angular event, the NgZone and ChangeDetectorRef calls to remove at the flip, and the IPC, player, observer, timer and dialog paths checked as signal-safe. On Angular 22 an unset changeDetection already means OnPush, so only the explicit Eager components re-render on every tick. zoneless-migration.spec.ts in the performance harness compares the checklist with the code: a new Eager component, or a converted one left unticked, fails it.

Their template state is already signals, signal inputs, immutable dialog data or fields written from template events, so they switch to OnPush without other changes. The epg-item-description spec mutated dialog data after creation and marked only the fixture's host view; it now marks the component's own view, which OnPush requires. The libs/ui playback and remote-control components stay Eager for their own PRs.
