Agent Skills: lisa-improve-harness

Investigate ONE failed or expensive factory trajectory and prove whether a fix helped. Records the job contract, observes the baseline, locates the earliest failed handoff, classifies the gap as exactly one of context | capability | domain-ownership | authority | proof | feedback-delivery | worker-limitation, makes the smallest owning intervention at the authoritative owner (larger changes become a proposed-intervention ticket and the loop stops), verifies at both layers (native gates plus the operational journey), then reruns the same job class in a fresh session and isolated worktree behind a relevance gate — a rerun that never retrieved or invoked the intervention yields no-evidence-for-intervention, never retain. Terminates by posting a fingerprinted result record on the originating work item with decision retain, revise, remove, or test-without. Headless-safe, idempotent per trajectory, single-trajectory bounded claims only.
