That split verdict is a partner-side processing issue no resend fixes — someone at the partner has to correct it. This endpoint finds every partner currently in such a state and writes each one a mail naming what stands accepted, what was rejected when, and the partner's own rejection reason, asking for correction. **Addressing**: the mail goes to the contact address from the partner's **own PARTIN** (`COM+…:EM`), deliberately not to the BDEW list address — the PARTIN names the working Marktkommunikation desk. Partners who never sent a PARTIN are listed under `skipped`, never silently dropped. **Idempotence**: one mail per standing rejection, tracked in a ledger. Calling again mails nothing until a *newer* rejection appears. A failed send is reported (`skip: "Versand: …"`) and retried on the next call. CONTRL error 26 (duplicate transmission file) is excluded: that one is fixed by our own fresh-reference resend, not by the partner. Start with `dry_run: true` — it returns the full target list with addresses and reasons without sending anything. ## OpenAPI ````yaml /setup/internal-openapi.json post /v1/process/market-partners/korrektur-mails openapi: 3.1.0 info: title: n:lead Scheduling Bridge — Internal API version: 0.4.0 description: >- Internal API of the n:lead scheduling bridge: the process endpoints that drive the day-ahead pipeline (aggregate, publish the open position, submit schedules, generate forecasts, orchestrate) and the operator console endpoints.
