{label} release metadata does not bind the authenticated leg

Error message

{label} release metadata does not bind the authenticated legacy release manifest

What it means

This error is thrown by verify_release_extension when the extension's legacy_release section fails to bind the downloaded legacy release manifest: either metadata_asset/metadata_blake3 in the extension do not match pointer.release, or the BLAKE3 hash of the actually-downloaded legacy manifest bytes does not equal the metadata_blake3 recorded in the extension. This cryptographically ties the legacy manifest you received to the release metadata, so a tampered or wrong manifest is rejected.

Solutions

1. Re-download both the legacy manifest and the extension metadata from the authenticated release and retry — a transient corruption is the most common cause
2. Verify the legacy manifest's blake3 hash manually and compare with the metadata asset name/hash recorded in the channel pointer
3. Republish the release so extension metadata and legacy manifest are generated from the same pipeline run
4. If operating a mirror, ensure assets are served byte-identical (verify checksums after sync)

Example fix

// before: serving a re-uploaded manifest without updating extension metadata
legacy_release.metadata_blake3 = "<hash of OLD manifest>"  // downloaded manifest is new
// after: regenerate metadata after the manifest is final
legacy_release.metadata_blake3 = blake3::hash(final_manifest_bytes).to_hex()

    ext.legacy_release.metadata_asset == pointer.release.metadata_asset
        && blake3::hash(manifest_bytes).to_hex().as_str() == ext.legacy_release.metadata_blake3
}

match verify_release_extension(&bytes, &manifest, &pointer, target, kind, targets, label) {
    Ok(blake3) => proceed(blake3),
    Err(e) if e.to_string().contains("does not bind") => {
        eprintln!("legacy manifest corrupted or mismatched; re-downloading assets");
        redownload_and_retry();
    }
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling resolve_target_blake3 / verify_musl_extension / verify_windows_extension when the legacy manifest bytes were corrupted in transit, the wrong manifest asset was downloaded, the extension's legacy_release.metadata_asset or metadata_blake3 differ from pointer.release, or the extension metadata was regenerated without updating the manifest hash.

Common situations: Partial/truncated download of the legacy manifest (hash differs); a mirror serving a modified manifest; release pipeline rebuilt the manifest after the extension metadata was signed; pointer advanced to a release whose metadata_asset name changed.
