Filtering after the assignment made every subset query a full decode (~15s on a 50MB container). full_decode_cached memoises it per container -- fingerprint is length plus three sampled 4KB windows, keyed with min_consistency, last four kept. Decoding five ships from Stage_S02 in turn: 10.5s for the first, then 48us-1.4ms. A stage now costs one decode rather than one per ship. Ten suites green, viewer builds, and a spot-checked resource still lands on the same offset. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

//! Time repeated per-ship decodes of one container, as the viewer does.
