- Cut face
- The exposed edge of a section, where every layer is visible at once. On this site, a story told with its surface, terrace and bedrock in view.
- Terrace
- The working layer of permits, quotas and schedules. It moves every season, which is why it produces most of the news that looks sudden.
- Bedrock
- Statute, treaty and compact. Slow to change, expensive to challenge, and usually the reason a surface fix does not hold.
- Filing
- The act of putting a document where the public can find it, with a stamp and a date. The desk treats the stamp as evidence.
- Standing body
- A commission or board that exists whether or not it is in the news. Its minutes are the closest thing to a continuous record.
- Tolerance
- The amount of variation a rule allows before enforcement changes. Most disputes are about tolerance, not about the rule itself.
