Portable verifier preparation

The evidence archives, CODE input and production source remained unchanged.

• portable-v1 failed because an unquoted get interpreted the dot in candidate-package.crate as a cell path. verify-first.nu.txt is its exact body. No source or gate was rerun.
• portable-v2 only added error detail; verify-diagnostic.nu.txt preserves it. Its raw stderr locates the same invalid lookup.
• portable-v3 quoted the literal key, passed package/source checks, then reached an unquoted conditional string (paired_repeat_required) interpreted as an external command. verify-third.nu.txt preserves this body.
• portable-v4 quoted the conditional strings and passed the full base/CODE, 103-record, source, package, API and threshold reconstruction. Its output is an actual PASS, not a prediction.

The final verifier additionally binds the later actual CODE review, launcher and statistic-field qualification as outer receipts. Its final replay has a separate receipt. Historical Ruby capture helpers remain provenance, not runtime tools.
