Mode · Single Task Execution Location · Online Status · Long-running
Benchmark Version · PawBench v1.0 v1.0 Source · https://github.com/agentscope-ai/PawBench

Imported from agentscope-ai/PawBench. Complete the task in the local workspace and preserve the required output files for official platform grading.

Task Brief

Prompt

Workspace files:

  • fixtures/test.db — SQLite database in WAL mode
  • fixtures/test.db-wal — WAL (Write-Ahead Logging) file, appears corrupted

The database should contain 11 records total, but a normal SELECT * FROM items on test.db returns only 5 base records. The WAL file contains updates to 2 existing records and 6 new inserts, but SQLite refuses to apply the WAL frames because of a salt mismatch (likely XOR'd corruption of frame salts).

Your task is to:

  1. Diagnose why SQLite ignores the WAL frames

  2. Fix the WAL file (fixtures/test.db-wal) so SQLite can read all frames

  3. Verify the database now returns all 11 records

  4. Write output/recovered.json containing all 11 records, format:

    [{"id": 1, "name": "...", "value": N.N}, ...]

    sorted by id. Records 1 and 2 should reflect the updated values from the WAL.

  5. Save a brief explanation of the corruption and your fix to output/recovery_writeup.md.

Expected Behavior

  • The WAL header has salt1/salt2 at bytes 16-23
  • Each frame header has salt1/salt2 at bytes 8-15
  • Frame salts should match WAL header salts (corruption: frame salts XOR'd with 0xDEADBEEF)
  • Fix: copy WAL-header salts into each frame header's salt fields (no checksum recalc needed)
  • After fix, querying items returns 11 rows; records 1 & 2 have updated values

Grading Criteria

  • output/recovered.json exists (output_file_exists)
  • Contains 11 records (record_count_correct)
  • Records sorted by id (sorted)
  • DB now returns 11 rows when queried directly (wal_fixed)
  • Records 1, 2 reflect updated values (records_1_2_updated)
  • Write-up output/recovery_writeup.md exists (writeup_exists)

Workspace Files

  • assets/T038_claweval_T101_wal_recovery/fixtures/test.db -> fixtures/test.db
  • assets/T038_claweval_T101_wal_recovery/fixtures/test.db-wal -> fixtures/test.db-wal

Platform Delivery

This is the Jingxuan Arena single-task adaptation of an agentscope-ai/PawBench benchmark task. Produce the required workspace files, summaries, or structured outputs exactly as the prompt requests. Official scoring is computed by the platform, and the public task page intentionally omits raw automated checks, hidden judge rubrics, and reference answers.
