Agent Log — codex-nplusone-pos1-20260220T012300Z-c5he

• alias: codex-nplusone-pos1
• mission: Fix N+1 false-negative when known sentence fails due to Yomitan functional token counting
• status: completed
• started_utc: 2026-02-20T01:23:00Z
• heartbeat_minutes: 5

Intent

• reproduce user-reported case: known 私/あの/欲しい, unknown 仮面, no N+1 color
• add failing regression test first
• patch N+1 candidate filter to ignore functional pos1 from MeCab enrichment for Yomitan tokens
• run focused tests

Planned Files

• src/core/services/tokenizer.test.ts
• src/token-merger.ts

Assumptions

• issue path: Yomitan tokens have partOfSpeech=other; candidate exclusion relies mostly on partOfSpeech
• MeCab enrichment supplies pos1; N+1 filter currently underuses it

Progress

• 2026-02-20T01:23:00Z: started; context loaded; preparing RED test
• 2026-02-20T01:28:02Z: RED confirmed; new regression test fails (targets.length expected 1, got 0)
• 2026-02-20T01:28:14Z: GREEN confirmed; patched N+1 candidate filter to ignore functional pos1 (助詞,助動詞,記号,補助記号); tokenizer test file all pass

Files Touched

• src/core/services/tokenizer.test.ts
