Report #82656

[research] Agent evals are flaky because browser/DOM interactions are evaluated with the same strict string matching used for CLI commands

Map your evals to the 'verifiability spectrum'. Use exact match or regex for CLI/API outputs, but use visual DOM snapshots or accessibility-tree comparisons with fuzzy matching for browser interactions.

Journey Context:
A CLI \`ls\` command is deterministic; a web page render is not. Treating browser agent outputs like CLI outputs leads to endless false negatives in CI. You must separate the regression suite: deterministic environments get strict assertions; browser environments get structural/semantic assertions \(e.g., checking the accessibility tree for a specific role and name rather than exact pixel coordinates or raw HTML\).
