I read this as a read-only root-cause investigation - I’ll trace `NutritionOnboardingService.finalize`, enumerate every reachable `ValueError` for the live workflow, and compare each boundary against the live profile JSON.


The live workflow is confirmed as `finalizing`; I’m narrowing the trace to the concrete owner-approval call inputs and validating the nested boundaries in execution order, without invoking finalization.


I read this as a read-only root-cause investigation - I traced the live finalization path and classified each validation through the first failure.

## Finding: H1 confirmed

The most likely exact exception is:

```text
UnsafeGoalTrajectoryError: unsafe goal trajectory
```

Raised at:

- `dualcoach/profile/checkin_cli/nutrition_onboarding_calculations.py:126-127`
- Called by `generate_initial_plan()` at `nutrition_onboarding_calculations.py:159`
- Reached from `finalize_onboarding()` at `nutrition_onboarding_finalization.py:161`

### Triggering live values

From `baseline-candidate.json:1`:

- `goal_type = "loss"`
- `weight_kg = 82.3`
- `target_weight_kg = 75`
- `target_date = 2026-10-22`

From `telegram-customer-bootstrap-v1/ledger.json:1`:

- `starts_on = 2026-08-21`

The boundary computes:

```text
days = 62
weekly change = (75 - 82.3) / (62 / 7)
              = -0.8241935484 kg/week
rate = abs(-0.8241935484 / 82.3)
     = 0.0100145024
limit = 0.01
```

Because `0.0100145024 > 0.01`, line 126 rejects it. The minimum safe target over this interval is approximately `75.01057 kg`; the requested `75 kg` misses the boundary by only about `0.01057 kg`.

## Validation classification in execution order

| Boundary | Result | Evidence |
|---|---|---|
| Storage/path ownership | Pass | All relevant directories are owner-controlled `0700`, files `0600`, with no symlinks. |
| Current authority supplied | Pass | Runtime supplies `authority` at `telegram_nutrition_onboarding_runtime.py:277-285`. |
| Current registry authority | Pass | Customer exists uniquely, is disabled, has granted `privacy-v1` consent, and current customer/owner routes match the registry. |
| Workflow state | Pass | Live `workflow.json:1` has `"state":"finalizing"`; checked at `nutrition_onboarding_finalize_service.py:32-34`. |
| KST timestamp | Pass | Runtime uses `datetime.now(ZoneInfo("Asia/Seoul"))` at runtime line 279; validated at finalization lines 79-80. |
| Privacy digest | Pass | Live value is lowercase SHA-256 `9f6a...10f1`; boundary at lines 81-86. |
| Feature epoch digest | Pass | Feature-epoch file is absent, so runtime generates the canonical disabled-epoch SHA-256; boundary at lines 81-86. |
| Input reconciliation digest | Pass | `95261e...90f0` is a valid lowercase SHA-256; lines 88-95. |
| Baseline candidate digest | Pass | Recomputed digest exactly matches `f68370...fb2b`; lines 96-102. |
| Baseline model validation | Pass | Age 21, male basis, 183 cm, 82.3 kg, loss target fields and structured values all satisfy the model. |
| Restriction KB source template | Pass | Present and valid; effective `2026-08-01` through `2027-07-31`; lines 106-120. |
| Clinical receipt validation | Not taken | `clinical-review.json` is absent. |
| Owner-risk history | Pass | Receipt context matches customer, baseline and reconciliation; stored receipt digest recomputes exactly to `4700c0...63ed`; lines 142-152. |
| Medical/restriction gate | Pass via owner acceptance | Conditions and medications require review, but valid owner-risk history satisfies lines 154-160. |
| Equation basis | Pass | `"male"` produces BMR `1867`; decline exception at calculation lines 153-154 is not reachable. |
| Goal direction and positive duration | Pass | Loss direction is correct and duration is 62 days. |
| Weekly trajectory rate | **Fail** | `1.00145024% > 1%`; calculation lines 119-127. |

All later `ValueError` sites—macro reconciliation, generated-plan model checks, readiness audit, and registry projection—are unreachable because execution stops at the trajectory exception.

## Why the Golden Path misses it

The Golden Path answers declare a maintenance goal and explicitly omit target weight/date in `source_golden_path.py:47-69`. For maintenance, `_safe_weekly_change()` returns immediately at `nutrition_onboarding_calculations.py:109-111`, so the rate boundary at lines 119-127 is never exercised.
