-//     disturbed by upstream noise. errs.IsTyped is the discriminator.

-### Partial failure (batch / multi-status)
-
-A batch command (e.g. `drive +push` / `+pull` / `+sync`) that processes
-many items can finish in a third state, neither full success nor a single
-error: some items succeeded and some failed. Its primary output is the
-per-item result, so it does **not** belong in a `stderr` error envelope.
-
-Such a command returns `runtime.OutPartialFailure(data, meta)`, which:
-
-1. writes the full result to **stdout** as an `ok:false` envelope — the
-   summary and every per-item outcome (succeeded *and* failed) stay
-   machine-readable, exactly as a successful `Out(...)` would carry them,
-   but with `ok` honestly reporting failure; and
-2. returns `*output.PartialFailureError`, a typed exit signal the
-   dispatcher maps to a non-zero exit code while writing nothing further
-   to `stderr`.
-
-This is distinct from `ErrBare` (a predicate's one-bit answer) and from a
-typed `*errs.XxxError` (a `stderr` error envelope): a partial failure is a
-*result*, reported on stdout, that also failed. Consumers branch on
-`ok == false` and then read `data.summary` / `data.items[]`.
