publish package list contains duplicates

Error message

publish package list contains duplicates: {duplicate_crates}

What it means

validate_order receives the ordered publish crate list and raises this ValidationError if any crate name appears more than once, listing the duplicates sorted. Duplicate publish entries would cause a crate to be validated/published twice, so the list is rejected up front.

Solutions

1. Deduplicate while preserving order, e.g. list(dict.fromkeys(ordered_crates)), in the code that builds the publish list
2. Review the ordered crate list for repeated entries and remove duplicates
3. Check the config/CI step that generates the list for accidental double-appends
4. Re-run the validator after fixing the list

Example fix

// before
ordered = base_crates + new_crates
// after
ordered = list(dict.fromkeys(base_crates + new_crates))

ordered = ["codewhale-config", "codewhale-core", "codewhale-tui"]
dups = {n for n in ordered if ordered.count(n) > 1}
if dups:
    raise SystemExit(f"dedupe publish list first: {dups}")

try:
    validate_publish_order(...)
except ValidationError as e:
    if "contains duplicates" in str(e):
        print(f"dedupe the publish list: {e}")
        ordered = list(dict.fromkeys(ordered))

When it happens

Trigger: The publish-order configuration (ordered_crates, e.g. from release config or CLI args) accidentally lists the same crate name twice — typically from merging two lists, copy-paste, or a scripted append that didn't dedupe.

Common situations: CI workflow composing the crate list from two sources (base list + new crates) without deduplication; a maintainer hand-editing the release order and duplicating a line; programmatically generated lists where a filter was applied twice.
