# Model Update

Updating is not building. You know what changed in the world and you do not know what the file will do when you write into it, so the order below maps every data point to a treatment before a single cell moves, keeps the file the user gave you byte-identical, and leaves a reader able to see what changed and on whose authority.

Evidence labels, source tiers, staleness, the readiness posture and the intake limits: `.agents/skills/research-conventions/SKILL.md`, read before the first write.

Routing before you start:

- The workbook's own `Checks` sheet fails, or the model looks wrong before you touch it: audit it first with `.agents/skills/check-model/SKILL.md`.
- The refresh has to move operating metrics rather than the three statements: `.agents/skills/dcf-model/references/sector-drivers.md` lists what drives each sector.

## Step 1: Name the trigger and list the fields it touches

One update has one trigger. Name it, hold the document or the tool call that carries it, and write down the fields it reaches before opening the workbook.
