I/O refinement ledger¶

This page is derived from the original CSV; it is not a new status authority, execution record or software qualification. Original IDs, order and all fields come from the original ledger. Source: docs/design/platform-refinement-execution.csv; SHA-256: e4496e72ba53be176407804fffa805ef5b12f9da1e0949d2f3e8a20292d27e8b.

Different ledgers overlap in scope; do not add their counts or calculate a project-wide completion rate. Interpret implementation, software and physical status separately. development_passed does not mean execution at the current documentation HEAD. Consult the exact results index for the source and scope of qualification_record_authority. Absolute /workspace and /dev/shm locators retain their original bytes and only identify the original execution host. See the software-evidence entry for retrievable archives and member locations.

Original exit fields are only fields actually present in the original CSV. Tasks, qualification prerequisites and contract links also retain their original wording; they cannot be used to invent an execution.

This table contains 60 original records; this is only the source row count.
