- Around line 99-106: Validate the `push-forms` payload in its RPC handler
before calling `mergePageReport`: require a report with a string `pageId` and
array-valued `forms` and `events`, and ignore invalid payloads. Use the
package’s existing validation approach where appropriate, keeping valid reports
on the current `applyForms` path.

- Around line 85-89: Update the withoutValue sanitization used by
inspectFormsText so includeValues=false removes all value-bearing details from
error params and message, including params.value and values embedded elsewhere
in the message; do not rely only on filtering two parameter names and stripping
one suffix.
- Around line 195-199: Update the truncation fallback in the form-state
serialization path to retain a bounded event list, so events remain accessible
when serialized state exceeds MAX_TOOL_CHARS * 5; preserve the existing bounded
form data and truncation behavior.
- Line 293: Update the aggregate reportedAt calculation in stateOf to use the
oldest retained page’s timestamp, so a newer page does not mask stale forms;
return 0 when no pages are retained.

The only conflicts were the checked-in bundles under packages/ng-devtools-assets/dist, which this branch had no reason to touch. Take main's copies and drop the ones a local build left behind.
