# Replace Job Instruction Page

> Replace a complete canonical TipTap document with concurrency and live-write guards.

Replaces the complete page document. Requires `instructions:write` and
employer access. Preview the content first.

<ParamField body="content" type="object" required>
  The complete TipTap `doc` node.
</ParamField>

<ParamField body="expectedChecksum" type="string" required>
  The SHA-256 checksum from the last page read.
</ParamField>

<ParamField body="confirmReplace" type="true" required>
  Confirms the whole-document replacement.
</ParamField>

<ParamField body="confirmLive" type="true" required>
  Confirms immediate worker visibility.
</ParamField>

A stale checksum returns `409` instead of overwriting a concurrent edit.
