Function parse_remote_manifest

atomic-cli/src/commands/clone/helpers.rs:372–394

Parse and verify a view manifest downloaded from the remote. Validates three things before the manifest is trusted: 1. The text parses structurally (header + base32 change log). 2. The header names the view that was requested. 3. The declared merkle state equals the fold of the change log. # Arguments `view` - The view name that was requested from the remote `text` - The raw manifest text retu

(view: &str, text: &str, url: &str)

/// * `text` - The raw manifest text returned by the server
/// * `url` - The remote URL (for error context)
