The reading chapter derives a position's definition file from its name instead of looking it up; the agent catalogue says the locator finds the definition by its `position` frontmatter field.

The reading chapter derives a position's definition file from its name instead of looking it up; the agent catalogue says the locator finds the definition by its position frontmatter field.

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/04-surfaces/23-reading.md:187 — "The file is derived from the position, agents/cold-reading-<position>.md,"
• End B: .abcd/development/brief/05-internals/01-agents.md:317 — "the locator resolves a position to its definition by this field"

23-reading says the definition file is derived from the position as agents/cold-reading-<position>.md, 'rather than looked up', and that the frontmatter's position is only checked against it afterwards. 01-agents' frontmatter table says the locator resolves a position to its definition by the position field, which is a lookup over the prompts. A definition whose filename and frontmatter disagree would be found by one mechanism and missed by the other, so both accounts of resolution cannot be right.
