Method
  - Every day at about 06:20 UTC we read the public job boards (Greenhouse, Ashby and Lever) of the advanced nuclear employers listed in the company table and count the roles each one lists.
  - "Open roles" is the number of postings on the employer's own board that day. We leave out general-application and talent-pool postings (titles such as "General application"). One posting can name several places.
  - "Posted" is the date the employer's board gives for the posting (first published or created, depending on the board). It is not the date the job was filled or closed.
  - "Days since posted" describes roles that are still open. It is not time-to-fill: roles that were filled quickly have already left the data.
  - Role families come from keywords in the job title (the department when the title has none). States come from the location text; a role that names two states counts in each.
  - A day on which any employer's board does not answer has no row. We never record a failed read as zero.
  - When we add an employer, the column employers_tracked changes. Treat a jump on that day as a change in coverage, not in hiring.
  - Coverage: venture-backed and private advanced reactor, microreactor, fuel and services companies whose boards are public. Large vendors and utilities whose boards we cannot read (for example X-energy, NuScale, Holtec, Westinghouse, GE Vernova) are not included, so these are not totals for the nuclear industry.
