Warum

The post-merge release of the three new learning missions stopped in the existing Chain lab cancellation check. The inline search is stopped while the page clock is paused, but awaiting the React result paint before resuming that clock can strand the visibility check.

Was

Resume the page clock immediately after the frozen start/Stop sequence, then await the React status. Preserve the exact zero-attempt verdict and unchanged-hash assertions. No product code, search mode, timeout, dependency or ledger rule changes.

Verify

• Focused ESLint, syntax/diff checks and full local Chain lab flow passed. Disposable no-Stop mutation failed at the unchanged exact zero-attempt assertion; the real Stop flow passed with original hashes preserved.
• Exact head 41ed8f64993cfa74b90a2eb42b64744937937311: Web checks and Server checks passed. Web includes unit suite, Chrome, WebKit, lint/build and deploy check.
• Merged as 4f79ca6c4b9c708ba54f27f65e9e50641c36d350; master release passed the complete Web checks, publication, domain/build byte match and live browser acceptance.
• Independent read-only live check at 2026-11-07T15:52:41Z saw all three new missions, twelve total, no page errors and no mining/API writes. Ownership and immutable merge receipt were appended to the harden peer handoff for PR74 integration.
