Add lean_solved metric to progress chart

[Copilot]

Adds tracking for formalized proofs/disproofs/solutions (Lean) as a fourth metric in the visual progress chart, as requested in issue teorth#170.

Changes Made

• scripts/plot_statistics_history.py:

  • Added lean_solved to FIELDNAMES
  • Extended create_plot() with fourth line using gold (#d29922) / orange (#bf8700) colors
  • Updated legend labels to: "Solved", "Lean Formalized Problem", "Lean Formalized Solution", "OEIS Linked"
  • Added latest values as data point labels at the end of each line

• scripts/generate_readme.py:

  • Added lean_solved to current_stats: count_proved_lean(rows) + count_disproved_lean(rows) + count_solved_lean(rows)
  • Added count_solved_lean() function for "solved (Lean)" status (from upstream commit 0a1a662)
  • Updated build_table() to display the "solved (Lean)" category in the README

• data/statistics_history.csv:

  • Added lean_solved column
  • Backfilled historical values by checking each commit's problems.yaml for "proved (Lean)" and "disproved (Lean)" statuses

• .gitignore:

  • Exclude __pycache__/ and *.pyc

Original prompt

Problem

As requested in issue teorth#170, the visual progress chart should track an additional metric: the number of formalized solutions (proofs/disproofs formalized in Lean).

Current State

The progress chart in scripts/plot_statistics_history.py currently tracks three metrics:

• Team Lean (Formalized) - problems with statements formalized (lean_formalized)
• Team OEIS (Linked) - problems linked to OEIS sequences (oeis_linked)
• Team Solve (Proved+Disproved+Solved) - total solved problems (total_solved)

The scripts/generate_readme.py already has functions to count formalized proofs:

• count_proved_lean(rows) - counts problems with status "proved (Lean)"
• count_disproved_lean(rows) - counts problems with status "disproved (Lean)"

Required Changes

1. Update scripts/plot_statistics_history.py:

   • Add lean_solved to FIELDNAMES list
   • Update create_plot() function to read and plot the new lean_solved metric as a fourth line
   • Choose an appropriate color for the new line (suggest a fourth color like yellow/gold for dark theme and orange for light theme)
   • Update the legend label to something like "Team Lean Solved (Formalized Proofs)"

2. Update scripts/generate_readme.py:

   • Add lean_solved to the current_stats dictionary, calculated as count_proved_lean(rows) + count_disproved_lean(rows)

3. Update data/statistics_history.csv:

   • Add lean_solved column with value 0 for all historical entries (we can backfill accurate historical data later).

Notes

• The existing count_proved_lean() and count_disproved_lean() functions in generate_readme.py already count problems where status.state equals "proved (Lean)" or "disproved (Lean)" respectively.
• The chart should maintain visual consistency with the existing design.
• Historical data will be backfilled in a future update by tracing when each formalized proof was added to the repository.

This pull request was created as a result of the following prompt from Copilot chat.

@copilot Nice. Now, fill in the history for the formalized proofs.

@copilot Nice. Now, fill in the history for the formalized proofs.

Done in 9488904. I backfilled the lean_solved history by checking each commit's problems.yaml for "proved (Lean)" and "disproved (Lean)" statuses. The historical values are all 0 because these Lean-specific status values were only recently introduced - the chart shows a jump to 17 at the most recent data point.

@copilot This isn't right. The yaml has disproved lean back in September. This is the first one.

71e2361

I'd expect the count to be 2 proved + 1 disproved after that commit.

Fixed in 5376955. The issue was that my initial backfill ran on a shallow clone that didn't have the full git history. After fetching the complete history, the script now correctly identifies lean_solved values starting at 2 (Sep 1), growing to 3, then gradually increasing to 17.

[AlexisOlson]

@copilot Let's update the labels to something more like

Solved
Lean Formalized Problem
Lean Formalized Solution
OEIS Linked

What would you recommend?

Let's also add the latest values as a data point label on the end of each line.

Done in 9bf60ef. Updated the labels to:

• Solved
• Lean Formalized Problem
• Lean Formalized Solution
• OEIS Linked

Also added the latest values (413, 243, 17, 261) as data point labels at the end of each line.

@copilot Let's rebase to the latest main and take into account this recent commit:
teorth@0a1a662

I cannot perform a git rebase directly, but I've incorporated the changes from upstream commit 0a1a662 in 9e5e7b2. Added:

• count_solved_lean() function for "solved (Lean)" status
• Updated build_table() to display the "solved (Lean)" category
• Included count_solved_lean() in the lean_solved metric calculation
