| 3 | This is a compact compatibility entry, not a second workflow manual. The behavioral source of truth is [`skills/exam-cram/SKILL.md`](../../skills/exam-cram/SKILL.md) plus the selected control-layer subskill; wording dispatch is defined by [`docs/language-policy.md`](../../docs/language-policy.md). |

| 7 | Load the orchestrator, then exactly one needed subskill: [`exam-ingest`](../../skills/exam-ingest/SKILL.md), [`exam-tutor`](../../skills/exam-tutor/SKILL.md), [`exam-study-guide`](../../skills/exam-study-guide/SKILL.md), [`exam-quiz`](../../skills/exam-quiz/SKILL.md), [`exam-review`](../../skills/exam-review/SKILL.md), [`exam-cheatsheet`](../../skills/exam-cheatsheet/SKILL.md), [`exam-audit`](../../skills/exam-audit/SKILL.md), [`exam-help`](../../skills/exam-help/SKILL.md), or [`confusion-tracker`](../../skills/confusion-tracker/SKILL.md). Persisted `language` values are `zh|en|bilingual`; English is English-only, and bilingual is explicit-only. |

| 10 | |
| 11 | - Before local work, run `update_progress.py workspace-list --json`, confirm the absolute materials/workspace pair, and restore `study_state.json` first. It is progress truth; `study_progress.md` is generated. If state is absent and Python works, run `update_progress.py --workspace <ws> init` before `set`, `set-check`, or other writes. Never use the repository/cwd as the workspace. |
| 12 | - First contact establishes learning mode, time budget, and reply language together. Urgency may infer from-scratch + ≤1 day + the opening language; bilingual is never inferred. An explicit no-questions request sets `no_questions=true` and caps completion at `covered_unverified`. |
| 13 | - Choose material processing separately at startup. Missing/default means `processing_mode=lightweight`: current-phase PDF/raster batches only, maximum eight pages and one active batch, and no Study Guide. A saved `visual` preference is dormant/effectively `chat` until explicit `full`. Only reason-receipted `abandon` may close an unfinished lightweight batch; taught progress cannot be abandoned. |
| 14 | - Quiz and grading use only `references/quiz_bank.json`. Use `select_questions.py` normally and `select_hard_questions.py --chapter <current>` for a checkpoint. In a restricted pool, exclude/count untagged items; before a one-turn override say: ⚠️ Temporarily overriding your <scope> scope preference. |
| 15 | - For `requires_assets=true` or `maybe_requires_assets=true`, render every Question-side asset. Before asking, explaining, hinting, or solving, verify that every one is visibly rendered. A path is not an image. Show an Answer-side asset only later; if rendering fails, skip the item. Preserve but never display `student_attempt`: one declaration globally taints the same physical path across the question bank, teaching examples, and all content units, so another official-looking declaration cannot restore it. Use `show_question_assets.py` or the selected renderer's complete three-layer gate; never render the raw path directly. A `stub` or `page_reference` likewise needs visible original context first. |
| 16 | - Persist substantive work through `notebook.py`; report a failed write and provide the full content in chat. Missing/unknown `artifact_mode` means `chat`; only explicit full + `visual`, or a one-shot request after switching to full, enters typed Guide/render/QA, without silent installs or subscription guesses. |
| 17 | - At full-v2 Guide entry, first perform a host-capability handshake. If official host capabilities verifiably provide a fresh independent child context and can restrict both input and tools to one exact item, use the internal isolated subagent by default after one notice that it costs extra model quota and time; it needs no API key and makes no external upload. If any capability is incomplete (including tool restriction) or cannot be confirmed, use `ordinary` and say why. An external Provider is a fallback only when the learner explicitly names it; retain the two consents for Provider/API billing, retention/privacy, exact item/image scope, call count, current pricing, and upload. |
| 18 | - `preferences.interaction_style` stores only `batch|step_by_step` and is not an opening choice. A stored step preference is effective only in full mode with `no_questions=false`; otherwise it remains dormant and effective cadence is batch. Step selection uses one locked manifest-ordered snapshot and `record-taught-example` binds the marked notebook block and manifest item by hash. Teaching IDs use the shared 1–200-character Guide-safe Unicode contract. Unbound teaching IDs remain valid batch history, but bound IDs stay live-validated after cadence changes. A structurally sound stale binding or append-only new roster item mounts as `usable_with_gaps`; structural damage remains blocked and the old Guide/completion receipt must be rebuilt. Every teaching-baseline ID still needs a current teaching-manifest snapshot, not merely a quiz copy. |
