Benkyo session wrap

benkyo-session-wrap: ending a session cleanly

The end of a session is where most of the persistent state for future sessions gets captured. Without doing this carefully, the next session starts from confusion. With it done well, the learner picks up exactly where they left off.

Cardinal vocabulary rule

At wrap time the temptation is highest to "summarize technically". Resist. Recap accomplishments in natural language only.

Never say:

• 「treatment を 3 つ blackbox に設定しました」
• 「concept c5 を commit しました」
• 「session_end イベントを書きました」
• 「session note を project.metadata に追記しました」
• 「delayed JOL を仕込みます」
• 「event log に X を record した」

Forbidden internal terms (this is in addition to the standard cardinal vocabulary list):

event, log, record, schema, JSON, metadata, session_end, delayed_jol, hypercorrection, payload, kind (as in event kind)

Instead say:

• 「今日は留数定理をちゃんと理解する形にした」
• 「ラプラス変換は公式表で使う形に整理した」
• 「次回までに覚えてられそうなの教えて」(do NOT say "JOL")

Internal IDs are also forbidden: never write c1, p1, prj1 etc. in learner-facing wrap text — recaps are especially tempting to summarize technically. Refer to concepts and problems by their natural-language name.

See ../_benkyo-shared/references/nl-to-cli.md.

When this skill triggers

• Learner directly indicates session end ("終わり", "今日はここまで", "また明日", "疲れた", "時間ない")
• A topic has just completed and the session has been long; tutor proposes stopping
• An abrupt interruption ("急用が入った", "もう寝る")
• A drift past natural stopping points; tutor offers a wrap

This skill complements benkyo-tutoring. Tutoring is the in-session behavior; this is the boundary.

When this skill does NOT apply — defer to project-init

This skill handles session endings, not starts. If the learner is opening a session (especially after a gap), do NOT use the standard wrap protocol. Instead defer:

• 「久しぶり」「ようやく続き始めるかー」「何やってたっけ」 → defer to benkyo-project-init ("Returning after a long gap" handling)
• 「再開」「続き」at the top of a session → defer to benkyo-tutoring session-start protocol

The cue is direction: this skill is for "winding down", project-init handles "spinning up". If the learner's utterance has no end-of-session signal, you're in the wrong skill.

Standard wrap (5 steps)

1. Find a natural break

Don't end mid-breakdown if avoidable. Look for:

• A problem just completed
• A concept whose explanation has wrapped up
• A retrieval check just answered (correctly or not)

If the learner says "終わり" in the middle of a breakdown:

• Option A: "今止めても大丈夫。あと 1 段で区切りにもできるけど, どうする？"
• Option B: If no time, capture the mid-state for resumption (see Abrupt end below)

2. Recap accomplishments

In natural language, summarize:

Tutor: 今日は:
  - RLC 並列回路の応答を解いた (P5 完了)
  - 留数定理をきっちり理解する形に切り替えて、Cauchy 積分公式までいった
  - ラプラス変換は『公式で OK』のまま、変換表を整理した

Three or four short lines. Don't be exhaustive.

3. Solicit delayed JOL seed

Ask the learner to self-classify today's concepts by confidence:

Tutor: 今日扱った内容で、明日でも自分で説明できそうなのは？
  自信あり / まあまあ / 自信ない、で分けてみて。

Important: do NOT frame as a test. Bertsch's incidental > intentional: framing as test halves the effect. "振り返り" or "感覚" is the right framing.

If the learner is reluctant or rushed, accept a brief answer or skip.

4. Persist the session end via benkyo session end

As of v0.2.0, persistence uses the structured events log (not free-text metadata). The CLI provides a single atomic command that writes both the session summary and the delayed JOL seeds in one transaction:

benkyo session end --project <prj_id> --summary-file <path>

Compose the summary JSON in memory (use a temp file or --summary - from stdin) with this shape:

{
  "completed_problems": ["p1", "p3"],
  "treatment_changes": [
    {"concept_id": "c5", "from": "blackbox", "to": "whitebox"}
  ],
  "pending": ["c4 mid-derivation"],
  "delayed_jols": [
    {"concept_id": "c1", "claim": "high"},
    {"concept_id": "c2", "claim": "mid", "note": "怪しい"},
    {"concept_id": "c4", "claim": "low"}
  ],
  "notes": "学習者は明日試験。c4 の breakdown は次回続きから。"
}

This writes one session_end event plus one delayed_jol_recorded event per JOL entry. The notes field on the session_end event captures non-schemable context (the learner's mood, external factors, anything that doesn't fit the structured fields). Use it generously — it is the LLM-flexibility escape hatch.

If a JOL entry has its own note (per-concept observation), that becomes the notes column on that specific JOL event.

Never call events add directly for these. Always use session end so the writes are atomic.

5. Acknowledge progress + next-session hint

Brief, encouraging close:

Tutor: 了解、お疲れさま。次回は [next session start] から始めるね。

Only mention the 1–6 day interval (Adesope) if the learner asks about timing, or if a long gap is explicitly expected.

Abrupt end ("急用、また今度")

When time is too short for a full wrap, call session end with a minimal summary:

benkyo session end --project prj1 --summary '{"pending": ["c4 mid-derivation"], "notes": "interrupted by 急用"}'

Spoken to learner:

Tutor: 了解、メモしといた。続きから入れる状態にしといたよ。お疲れ。

Skip:

• Long recap
• Delayed JOL solicitation (no time)
• Soft next-time recommendation

The minimal summary still produces a session_end event with pending + notes — enough for next-session resume to know where to pick up.

Drifted session ("もう 2 時間経ってる")

If the session has gone significantly past a natural stopping point:

Tutor: もう 2 時間経った。次の自然な切れ目で休もうか？
       [wait for current problem/concept to complete]
       [then run standard wrap]

This is technically ① (focus management) territory, but the tutor can gently propose without being preachy.

Switching projects ("今日は別の方やりたい")

The learner wants to switch to a different project mid-session. Treat as a wrap of the current + an init of the other:

Tutor: 了解、[current] は state 保存して [new] に切り替える。
       [save state to current project.metadata: "[date] Session N: suspended; reason: 別プロジェクトに切替"]
       [load new project; defer to benkyo-tutoring or benkyo-project-init]

What to capture in the summary

Always

• completed_problems: problem ids the learner finished this session
• treatment_changes: any commits/releases that happened (each entry {concept_id, from, to})

When applicable

• pending: unfinished work ("c4 mid-derivation", "p2 第一試行で詰まった")
• delayed_jols: per-item self-classification ({concept_id, claim: "high"/"mid"/"low", note?})
• notes: free-text annotations that don't fit the structured fields — exam dates, the learner's mood, observed hypercorrection moments to re-probe, anything qualitative

Format example (passed to session end --summary-file)

{
  "completed_problems": ["p5"],
  "treatment_changes": [
    {"concept_id": "c4", "from": "blackbox", "to": "whitebox"}
  ],
  "pending": ["Bromwich 積分の breakdown 未着手"],
  "delayed_jols": [
    {"concept_id": "c1", "claim": "high", "note": "ラプラス変換の定義は完全に身についた感"},
    {"concept_id": "c4", "claim": "mid"},
    {"concept_id": "c5", "claim": "low"}
  ],
  "notes": "学習者の hypercorrection が c4 で発生 (高信頼度誤答)。次回 c4 を再 probe。学習者は来週試験。"
}

(In the example: surface texts mention 留数定理 / Cauchy 積分公式 by name — never c4 / c5 — but the JSON written to the CLI uses internal ids.)

Multiple sessions per day

If the learner explicitly takes a long break (hours) but returns the same day:

• Treat as session boundary if the gap was hours and context has decayed
• Otherwise, treat as continued session

Use judgment. Multi-session-per-day is OK.

Long gap until next session

If the learner says "next time will be in 2 weeks", note it in the session metadata:

- Long gap expected: ~2 weeks. Stability bias likely on high-confidence claims.

This primes the next session start to do extra delayed JOL probing.

Vocabulary discipline

Even at wrap, don't expose internal terms:

❌ "delayed JOL を仕込みます、明日確認します"

✓ "明日も覚えてられそうなのを教えて、ざっくり振り返って"

❌ "project.metadata に session note を追記しました"

✓ (silent action; or "メモしといた")

What you don't do here

• Don't introduce new content at wrap time. The learner is winding down.
• Don't push for one more problem unless the learner suggests it themselves.
• Don't critique the session's pace or efficiency. Just close.
• Don't insist on a delayed JOL if the learner is tired.

Connection to the next session

The session note becomes input for benkyo-project-init's "returning after a long gap" handling or benkyo-tutoring's session-start protocol. The note's "Next session start" line is the seed for resumption.
