Read-only analysis; NO file edits or implementation. STOP WHEN: an executor could implement contracts without product judgment.\n\n<Category_Context>\nYou are working on DEEP LOGICAL REASONING / COMPLEX ARCHITECTURE tasks.\n\n**CRITICAL - CODE STYLE REQUIREMENTS (NON-NEGOTIABLE)**:\n1. BEFORE writing ANY code, SEARCH the existing codebase to find similar patterns/styles\n2. Your code MUST match the project's existing conventions - blend in seamlessly\n3. Write READABLE code that humans can easily understand - no clever tricks\n4. If unsure about style, explore more files until you find the pattern\n\nStrategic advisor mindset:\n- Bias toward simplicity: least complex solution that fulfills requirements\n- Leverage existing code/patterns over new components\n- Prioritize developer experience and maintainability\n- One clear recommendation with effort estimate (Quick/Short/Medium/Large)\n- Signal when advanced approach warranted\n\nResponse format:\n- Bottom line (2-3 sentences)\n- Action plan (numbered steps)\n- Risks and mitigations (if relevant)\n</Category_Context>"},"host_pid":1353625,"final_response":"I read this as a request to close the design on two remaining choices - I’ll select the smallest robust option-2 publication pattern and lock unknown semantics for every `nutrition_daily` field.\n\n## Bottom line\n\n**Decision 1:** publish exactly one new card containing the confirmation prefix, progress, and next question; do not edit the old card or send a second content card. **Decision 2:** store unknown as field metadata separate from `answers`, emit `None`/omitted canonical fields, and never convert unknown into zero, normal, adherence, or any inferred metric.\n\n## Action plan\n\n### 1. Decision: one new confirmation-plus-next-question card\n\nAfter every accepted text or button answer, commit the domain transition and send one new card:\n\n```text\n✅ 답변을 기록했습니다.\n진행 {completed}/{total}\n\n다음 질문\n{question}\n```\n\nUnknown:\n\n```text\n✅ ‘잘 모르겠어요’로 기록했습니다.\n진행 {completed}/{total}\n\n다음 질문\n{question}\n```\n\nEdited answer:\n\n```text\n✅ 수정한 답변을 기록했습니다.\n진행 {completed}/{total}\n\n다음 질문\n{question}\n```\n\nFinal answer:\n\n```text\n✅ 답변을 기록했습니다.\n진행 {total}/{total}\n\n입력을 모두 마쳤습니다.\n답변 내용은 이 화면에 다시 표시하지 않습니다.\n```\n\n#### Publication contract\n\n1. The new card is the sole content-publication operation for an accepted transition.\n2. Do not edit the old card, remove its keyboard, or send a separate confirmation.\n3. For callbacks, `answerCallbackQuery(\"✓\")` is best-effort acknowledgement only; it is not the confirmation UX.\n4. The old card remains visible, but its callback version is stale immediately after the domain commit.\n5. Reusing an old button returns a toast only and causes no new card or mutation.\n6. Before sending, persist the new domain step/version and binding presentation state as `pending`.\n7. On success, persist `delivered`, message ID, presented step, and presented version.\n8. On any transport failure:\n   - `not_sent`: preserve the transition; no automatic retry;\n   - `unknown`: preserve the transition; no automatic retry;\n   - explicit Start/Resume publishes the current question later.\n9. Restart never republishes `pending` or `unknown` automatically.\n10. Final-save publication failure cannot roll back or duplicate the canonical event.\n\nThis is smaller and safer than edit-old-plus-send-next: it removes a second ambiguous Telegram write, avoids ordering races between two messages, and gives identical chronology for typed and button answers.\n\n### 2. Unknown storage contract\n\nAdd fields without changing the existing private `answers` representation:\n\n```python\nstate_schema_version: int = 2\nunknown_steps: tuple[str, ...] = ()\n```\n\nFor every field `F`:\n\n```text\nKnown(F)      := F in answers and F not in unknown_steps\nUnknown(F)    := F not in answers and F in unknown_steps\nUnanswered(F) := F not in answers and F not in unknown_steps\n```\n\nThese states are mutually exclusive.\n\nTransitions:\n\n- Known answer: set `answers[F]`; remove `F` from `unknown_steps`.\n- Unknown answer: remove `answers[F]`; add `F` to `unknown_steps`.\n- Edit known to unknown: perform the unknown transition.\n- Edit unknown to known: perform the known transition.\n- Unknown counts as completed progress.\n- Unknown callback action is opaque `u`; callback data contains no value.\n- Never infer unknown from free text such as “모름” or “기억 안남”; only the explicit button/action creates unknown state.\n\n### 3. Exact per-field event semantics\n\n| Step | Unknown private state | Typed `ContractCheckin` | Canonical JSON |\n|---|---|---|---|\n| `bodyweight` | `unknown_steps += bodyweight` | `body_weight_kg=None` | field omitted |\n| `calories` | `unknown_steps += calories` | `calories_kcal=None` | field omitted |\n| `macros` | one unknown marker for the composite | `carbohydrate_g=None`, `protein_g=None`, `fat_g=None` | all three omitted |\n| `meals` | `unknown_steps += meals` | `meal_summary=None` | field omitted |\n| `water` | `unknown_steps += water` | `water_liters=None` | field omitted |\n| `sleep_duration` | marker only | `sleep_hours=None` | field omitted |\n| `sleep_quality` | marker only | `sleep_quality_1to5=None` | field omitted |\n| `digestion` | marker only | `digestion_summary=None` | field omitted |\n| `condition` | marker only | `readiness_1to5=None` | field omitted |\n| `appetite_stress` | marker only | `appetite_stress_summary=None` | field omitted |\n| `training_summary` | marker only | `training_summary=None` | field omitted |\n| `optional_note` | unknown not offered | “없음” stores private empty string | `notes=None`, field omitted |\n\nAdditional rules:\n\n- All fields except `optional_note` show `잘 모르겠어요`.\n- `optional_note` retains `없음` and `직접 입력`.\n- An all-unknown submission still creates one accepted `nutrition_checkin` event with an empty/partial `ContractCheckin`; it records that the check-in was completed without inventing measurements.\n- The finalized private session retains `unknown_steps`; the canonical event represents unknown as missing fields rather than schema-expanding sentinel strings.\n- Corrections preload `unknown_steps` from the latest finalized private session.\n- A correction changing known to unknown supersedes the previous event and removes that metric from the current corrected record.\n\n### 4. Downstream missing-data rules\n\nUnknown must remain missing everywhere:\n\n- Unknown bodyweight or calories makes the event ineligible for the existing trend projection, which requires both.\n- Unknown calories is not zero and does not trigger the low-calorie safety rule.\n- Unknown macros are not calculated from calories.\n- Unknown meals are not “off plan.”\n- Unknown water is not zero intake.\n- Unknown sleep or condition is not normal, poor, or any score.\n- Unknown digestion is not normal digestion.\n- Unknown appetite/stress is not a neutral score.\n- Unknown training is not rest, missed training, or completed training.\n- Unknown trigger fields do not activate adaptive follow-ups; they also do not prove the normal branch.\n- Adherence and coaching projections must classify missing evidence as missing, never adherent or non-adherent.\n\n### 5. Progress and previous-answer behavior\n\n```text\ncompleted = known fields + unknown fields + optional-note “없음”\ntotal = 12 + active adaptive follow-ups\n```\n\nPrevious-answer editing preserves the old answer while editing:\n\n- entering edit mode does not change progress;\n- replacement known/unknown atomically replaces the old state;\n- later base answers remain intact;\n- only adaptive answers invalidated by the replacement are removed;\n- cancellation restores the original continuation point.\n\nNo confirmation card may contain the old or new value.\n\n### 6. Legacy and active calories-step migration\n\nMigration is lazy and additive:\n\n- Missing `unknown_steps` loads as empty.\n- Existing `answers` remain known exactly as stored.\n- Existing text such as “기억 안남” remains legacy free text; do not reinterpret it.\n- Existing finalized drafts and events are not rewritten.\n- New fields serialize only on the next successful session mutation.\n- Corrupt or contradictory known/unknown state fails closed without rewriting bytes.\n\nFor the currently active calories-step draft:\n\n- preserve the same session ID, customer boundary, KST day, version 1, `calories` step, and existing answer;\n- infer `unknown_steps=()`;\n- report new progress as `1/12`;\n- retain the existing binding and expiry;\n- do not edit its existing Telegram message during deployment;\n- known calories advances once to `macros`, version 2, progress `2/12`;\n- unknown calories also advances once to `macros`, but stores no calorie value;\n- exact Telegram update replay cannot advance past `macros`;\n- deployment or restart creates neither an event nor a replacement draft.\n\n### 7. Required acceptance tests\n\n1. Accepted text and callback answers each cause exactly one new content card and zero old-card edits.\n2. Every new card includes confirmation, completed progress, and the next question without the submitted value.\n3. Old-card callbacks are stale after the domain commit and cannot mutate state.\n4. `not_sent` and ambiguous send outcomes trigger zero automatic retries.\n5. Restart from `pending` or `unknown` publishes nothing until explicit resume.\n6. Unknown is tested for all 11 supported fields and maps to the exact `None` fields above.\n7. Unknown macros omit all three macro values.\n8. Optional note exposes no unknown action.\n9. Unknown bodyweight/calories produces no trend-eligible row.\n10. Unknown values never become zero, normal, rest, or adherence evidence.\n11. Known-to-unknown and unknown-to-known corrections supersede exactly once.\n12. Legacy drafts load unchanged, and the current calories-step fixture advances exactly once from version 1 to 2.\n13. Sentinel answer values are absent from bot text, callback data, logs, bindings, and publication receipts.\n\n## Risks and mitigations\n\n- **Old cards retain clickable keyboards:** version and message/session checks make them harmless; avoiding cleanup is what keeps publication to one robust write.\n- **Unknown loses explicit distinction in the canonical event:** the finalized private session retains that distinction, while the event safely expresses only “metric absent.”\n- **Partial check-ins may provide insufficient coaching evidence:** downstream logic must report missing evidence rather than infer values.\n- **Current prompt uses the former question-position progress convention:** leave that live message untouched; apply completed-count progress on the next answer or explicit resume.","run_stats":{"runtime_ms":1252999,"turns":18,"tool_calls":70,"output_tokens":31301,"input_tokens":578407,"cache_read_tokens":2685440,"total_tokens":3295148,"generation_ms":1224021,"tokens_per_second":26,"cost_usd":6.389047000000001,"cache_hit_rate_last":0.8817441849360638,"cache_hit_rate_run":0.8227836660235606,"token_status":"complete","cost_status":"reported","duration_status":"monotonic"},"task_seq":23,"config_generation":0,"background_mode":"background"}
