# ROOM TRACE — every number in the room, record → label → caveat

`company/room/` · 3 October 2026 · the room's trace under the same standing
laws as `company/CLAIM-TRACE.md` (S1–S8, restated below). A number in
`company/room/content.py` that cannot be placed here makes the build fail
(`tools/build-room.py` refuses untraced numbers). Chart data values are read
from the cited `qa/` records at build time by the same build and carry their
provenance in the chart captions (S8 treatment).

## 1. Standing laws (S1–S8, from company/CLAIM-TRACE.md)

| # | Law | In the room |
|---|---|---|
| S1 | Fractions of a box are never probabilities | §01 stat cards, MC box chart footnote, §06 readbox |
| S2 | Contract box = fixed-price EPC + long-tenor debt; assumed, not a guarantee | §01 body |
| S3 | Every $/kW quote states scope: installed vs equipment, gross vs net | §04 P-E3 rows, §08 risk 5 |
| S4 | Ladder rows are different project definitions — never additive; spec and real-cost are two series | §00 chart, §01 chart caption |
| S5 | Label vocabulary: measured · verified · vendor-stated · model · simulated · inference · assumption · proposed · TBD | every number below |
| S6 | Zero measured duty hours, said in every materials set | §00 stats, §13 |
| S7 | The reinforced run reproduces R5 = $29.80 to 1e-9 before re-pricing | §01 body |
| S8 | Structural numbers are identifiers (sections, claims, records, contracts), not claims | §6 register below |
