publish package list contains duplicates: {duplicate_crates}

Error message

publish package list contains duplicates: {duplicate_crates}

What it means

The positional 'crates' arguments -- the maintained publication order, normally sourced from scripts/release/crates.sh -- contain the same crate name more than once. Duplicates would double-publish and corrupt the position arithmetic used for the topological check, so they are rejected before anything else in validate_order(). The sorted duplicate names are listed in the message.

Solutions

1. Remove the duplicate entries named in the message from scripts/release/crates.sh (the message lists them sorted)
2. Sanity-check the list for dups before release: printf '%s\n' $(cat scripts/release/crates.sh list) | sort | uniq -d
3. Re-run scripts/release/validate-crate-publish-order.py to confirm

Example fix

# scripts/release/crates.sh: before
crates=(codewhale-protocol codewhale-tui codewhale-protocol codewhale-cli)

# after
crates=(codewhale-protocol codewhale-tui codewhale-cli)

ordered_crates = ["codewhale-protocol", "codewhale-tui", "codewhale-cli"]
if len(set(ordered_crates)) != len(ordered_crates):
    from collections import Counter
    dupes = [c for c, n in Counter(ordered_crates).items() if n > 1]
    raise SystemExit(f"duplicate crates in publish list: {dupes}")

When it happens

Trigger: A copy-paste slip adds a crate twice to the ordered list in scripts/release/crates.sh; a merge conflict resolution keeps both copies of a line; invoking the validator manually and passing a name twice.

Common situations: Editing crates.sh while adding a new crate to the release inventory.
