Backup manifest statistics do not match its entries

Error message

Backup manifest statistics do not match its entries

What it means

Thrown when the manifest's declared stats counts disagree with the actual array lengths: sessionCount must equal sessions.length, resourceCount must equal resources.length, and warningCount must equal warnings.length. Note that deduplicatedResourceCount is intentionally NOT checked here.

Solutions

1. Recompute stats from the arrays right before packing the manifest.
2. Set sessionCount = sessions.length, resourceCount = resources.length, warningCount = warnings.length.
3. Re-export.

Example fix

// before
validateBackupManifestGraph(manifest)

// after
manifest.stats = {
  ...manifest.stats,
  sessionCount: manifest.sessions.length,
  resourceCount: manifest.resources.length,
  warningCount: manifest.warnings.length,
}

function statsMatchEntries(manifest: BackupManifest): boolean {
  return (
    manifest.stats.sessionCount === manifest.sessions.length &&
    manifest.stats.resourceCount === manifest.resources.length &&
    manifest.stats.warningCount === manifest.warnings.length
  )
}

try {
  validateBackupManifestGraph(manifest)
} catch (error) {
  if (/statistics do not match/.test((error as Error).message)) recomputeStats(manifest)
  throw error
}

When it happens

Trigger: manifest.stats.sessionCount / resourceCount / warningCount differs from the corresponding array length.

Common situations: Stats computed before entries were finalized; a hand-edit that added/removed an entry without updating stats; an exporter off-by-one.
