# Capture To Case

`POST /v1/cases/{case_id}/capture`

## Request

- Base URL: `https://api.bitpoort.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.bitpoort.com/v1/cases/{case_id}/capture`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

R3a — the generic "freeze into case": the caller names a TOOL and its
knobs; the SERVER re-executes it (executor dispatch or the app's own MCP
tool registry) and freezes the server's envelope. Caller result bytes are
never accepted — the two-lane law is structural. The captured event is the
analyst-act record (the run-event catalog stays closed); every captured
kind automatically gains rerun→diff, the human renderer, and
document-block use.
