Every figure in this report carries a grade, and nothing is presented as fact that is an estimate. This is the pipeline from raw signal to published number, and the sources behind it.
The methodology pipeline has five stages: one, the signal, drawn from customs flow, vendor disclosure, grid filings, named-project construction and market data; two, triangulation, reading those sources against each other to build a reconciled estimate; three, grading each figure Verified, Announced, Contested or Estimated; four, scoring the graded figures on one common frame to index the markets; five, publishing many views onto that one graded record.
Every number in the report carries one of four grades. The grade is a claim about evidence, not importance, and it decides how the figure may be read.
No single source is trusted on its own. Each is weighed by where it sits on this ladder, and a claim is only as strong as the highest rung that supports it.
When two sources conflict, the higher rung wins and the conflict is shown, not hidden. A figure resting only on rungs five or six is never graded Verified.
