• alias: opencode-task77-sliceb

Current Work (newest first)

• [2026-02-21T23:27:40Z] complete: added parser-enrichment-stage.ts with extracted pure overlap + surface-sequence enrichment helpers and narrow API enrichTokensWithMecabPos1; added focused stage tests; verified bun test src/core/services/tokenizer/parser-enrichment-stage.test.ts passes (3/3).
• [2026-02-21T23:26:40Z] tdd: created parser-enrichment-stage.test.ts first; confirmed RED due to missing module; then implemented stage module to GREEN.
• [2026-02-21T23:25:07Z] intent: extract pure MeCab pos1 enrichment logic into dedicated stage module, add focused stage tests, run requested target test command.
• [2026-02-21T23:25:07Z] progress: loaded Backlog overview + TASK-77 context; preparing red-first tests for parser enrichment stage.

• src/core/services/tokenizer/parser-enrichment-stage.test.ts

Assumptions

• TASK-77 remains active and this request maps to implementation plan step 2.
• Scope excludes edits to src/core/services/tokenizer.ts in this slice.

Open Questions / Blockers

• None.

Next Step

• Handoff slice-B result to user; no tokenizer orchestrator edits in this slice.
