Objective

Implement the Black Box DF rescue-ablation runner and tests.

Notes: Implemented research-only shared-panel 1.3%-versus-zero rescue-cap runner with branch-isolation, allocation-bound/coverage, and output-contract tests; smoke run succeeded; production default unchanged.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t359. Summary reconstructed from research/findings/task-history.json entry and git history. Uncertain fields: detailed approach, exact file list, and metrics beyond the task note.

Files / code / data changed

• No commit SHA confidently associated with t359 in sampled log [reconstructed — uncertain].
• Task-history entry: research/findings/task-history.json#t359

Results
