Recover transient hosted Custom Meta 404 responses

Objective

Recover transient hosted Custom Meta 404 responses.

Notes: Custom Meta optimization retries the identical canonical request once on HTTP 404 and replaces persistent generic errors with route-specific local-fallback guidance. Transient-success and persistent-failure Chromium coverage passes in the 22-test focused suite; screenshot and feature-completion notes are in research/findings/custom-meta-all-candidates-queue.md.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t328. Summary reconstructed from research/findings/task-history.json entry and git history. Uncertain fields: detailed approach, exact file list, and metrics beyond the task note.

Results

Task note: Custom Meta optimization retries the identical canonical request once on HTTP 404 and replaces persistent generic errors with route-specific local-fallback guidance.

[reconstructed — uncertain] No quantitative tables recovered for this entry; see git diff and task-history for grounds.
