Review comments at @app/src/pages/component-tree.ts:
- Around line 455-459: Update the unknown change-detection note in the
component-tree rendering logic to use an explicit unresolved-expression field
rather than `changeDetectionDeclared`. Add and populate that field in the
relevant `ComponentInfo` interfaces, `ComponentSchema`, and `get-components.ts`
RPC response so unresolved expressions show the scan-resolution note while other
unknown values show the Angular-version note.
Review comments at @packages/ng-devtools/src/rpc/angular-version.ts:
- Around line 40-47: Update readJson to return Record<string, unknown> and
validate the parsed JSON is a non-null object before returning it, falling back
to an empty object otherwise. In angularMajor, validate that dependencies and
devDependencies are objects before reading @angular/core, so invalid metadata
yields an unknown major rather than throwing.
Review comments at @src/app/examples/eager-clock.ts:
- Line 27: Update the setInterval callback that increments this.ticks to notify
Angular of the change by marking the component for checking through
ChangeDetectorRef. Preserve the existing one-second interval and tick increment.

AGENT: Verdict: request changes. The source scan is solid, but the UI targets a layout that no longer exists, and the live view already shows change detection.
app/src/pages/component-tree.ts:101-112(this PR): this block goes into the old source-list panel (h4,prop-chip,selectedProviders), and none of that is on main anymore. On main, the live detail panel already shows change detection atcomponent-tree.ts:218-219. It reads the value from Angular's runtime metadata, which is more reliable than a source scan. So please drop this block. Add one row to the source fallback's facts list instead (component-tree.ts:470-481on main, next to "Standalone"):<dt>Change detection</dt><dd>{{ comp.changeDetection ?? 'Unknown' }}</dd>. That's the only place where the scan adds something new.packages/ng-devtools/src/component-tree.ts:29on main maps runtime value1to'Default', but this PR labels the same valueEager. If both land as they are, the live view and the source view will disagree. Please update that map to{ 0: 'OnPush', 1: 'Eager' }in this PR so both views say the same thing, and add a test for value1incomponent-tree.test.ts(only0is covered today).app/src/pages/component-tree.ts:258-277(this PR): the new chip styles use hard-coded hex colors.#71717aon#3f3f46(theunknownchip) is about 2.2:1, which fails WCAG AA. Once the row is a plain<dd>as in point 1, you won't need these styles. If you keep a chip, use the tokens:@include m.soft(var(--ok))for OnPush andvar(--text-2)for the note.packages/ng-devtools/src/rpc/get-components.ts:49, 76(this PR): main replaced the hand-rolledwalk()withwalkFiles()and addedclassName,lineand av.picklistkind. After the rebase, threadmajorthroughscanComponents→componentsInonly.walkis gone, so there's nothing to change there. Keep the schema additions next to the new fields.packages/ng-devtools/src/rpc/get-components.ts:153(this PR): themajor >= 22default logic and the tests for it look right. Nice work covering the masked-template case and the directive case. Please keep all of that through the rebase.src/app/examples/eager-clock.ts:4-8: the doc comment talks about CLAUDE.md rules. Please cut it to one line about what the example shows, for example "Eager on purpose:ticksis a plain field, so OnPush would never see it change."- The PR commits rebuilt
extension/ui/assets/*. Those will conflict on every rebase. Regenerate them withpnpm extension:buildas the last step, after the rebase.
Needs a rebase onto main.

Review comments at @app/src/pages/component-tree.ts:
- Around line 24-25: Update the source-list detail template to render
comp.changeDetection and indicate its declared or implicit status using
comp.changeDetectionDeclared. This must show OnPush or Eager metadata when no
live page is connected, independently of the live-tree Detail.changeDetection
value.
Review comments at @packages/ng-devtools/src/rpc/get-components.ts:
- Line 154: Update the `CHANGE_DETECTION_KEY` lookup in `getComponents` to
inspect only top-level properties of the component decorator arguments, ignoring
nested matches such as properties inside `providers`; then parse the selected
top-level `changeDetection` value so nested values cannot override the component
setting.
- Around line 161-163: Update the change-detection strategy parser that uses the
OnPush, Eager, and Default checks to match complete supported values rather than
finding strategy names inside expressions. Return unknown for conditional
metadata expressions the scanner cannot evaluate, while preserving recognition
of the supported standalone names and numeric values.

Thanks, this is close. One thing left: the rebase left duplicate declarations in app/src/pages/component-tree.ts. LiveNode, Prop, Dependency, Detail and Page are each declared three times now. Please keep one copy of each. Small nit while you're there: const kind = scope.kind ?? 'component' can just be scope.kind, since the line above already returns when it's empty. After that it looks good to me.
