-## Atomic Notarius promotion unsupported
-
-Symptom:
-
-- extraction fails with `atomic no-replace directory promotion is unsupported`
-  before a durable bundle or temporary promotion tree is created.
-
-Likely cause:
-
-- Narratio is running on an operating system other than Linux, macOS, or
-  Windows, where the required atomic no-replace directory primitive has not
-  been implemented and verified.
-
-Safe fix:
-
-- run extraction on Linux, macOS, or Windows. Do not replace the atomic commit
-  with a manual copy or move; the session manifest must never observe a partial
-  or overwritten bundle.
-
-This is an extraction-specific platform boundary, not a support statement for
-unrelated Narratio workflows. See
-[Operations: Extraction Workflow](./operations.md#extraction-workflow).
