#459 aft_search trailer: (cap) for a page cut of a complete list; (walk) only when a walk limited coverage

Accepted agent delivery; branch-keyed search descriptor included.

---

Summary by cubic

Makes search trailer reasons truthful: page cuts of complete ranked lists now report cap, and walk appears only when a bounded fallback traversal left part of the project unexamined. Ranking and result contents are unchanged.

Details

• Exhausted ranked lists that omit results now use cap; a complete single-page list still prints no trailer.
• Fallback searches that hit a deadline or skipped foreign mounts report walk; otherwise they report cap.
• Added the land-search-trailer-cap.json benchmark descriptor and updated conformance and contract tests for the new reason semantics.

Confidence Score: 5/5

The PR appears safe to merge, with no outstanding actionable findings.

Summary

Search page cuts now report cap; incomplete fallback walks report walk.

• Ranked search pages call omitted results a cap.
• Fallback search reports walk only when scanning misses coverage.
