Today's Scan

No high-signal public items surfaced in this run.

Source Mix

No source mix available.

Best Use

Open only the first lane during a busy morning. Older recurring seeds are kept below the daily scan instead of competing with fresh items.

Start Here

The top few items most likely to matter for formal proof agents or Lean-facing AI4Math work.

No high-signal public items found in this run.

Worth Opening

Good candidates after the first three. These are plausible paper-tab opens, not a mandatory reading list.

Nothing else needs opening right now.

Watch Later

Adjacent formalization or infrastructure signals. Keep them in peripheral vision unless they match an active project.

No watch-later items in this run.

Older but Useful

0 relevant item(s) are outside the 21-day content window. Keep them for context, but do not let them drive today's scan.

No older useful items were retained in this run.

Downweighted 59 low-priority match(es), folded for daily reading.
