PAR2 generation in streaming mode depends on metadata generation without seeking (#148) and is not yet implemented. Requires either a two‑pass design or trade‑offs (e.g., storing parity blocks after the data).

PAR2 generation in streaming mode requires either a two‑pass approach (read, compute parity, write) or storing the entire stream in memory. Since streaming archives are typically used for pipelined operations where the source cannot be rewound, PAR2 generation is not practical. Moreover, streaming obviates PAR2: the primary use case for PAR2 is long‑term storage with corruption resilience, not transient streams.

Per user instruction, we are punting on this sub‑task. Closing as deferred/wontfix.
