Summary

• Strengthen feedback escalation tests for repeated failures and assisted success states.
• Verify stable metadata such as assist level, hintShown, assisted, and failure count without pinning full copy strings.
• Replace brittle CSV substring checks with checks against the final assist-related CSV fields.
• Add a small reason-hint fallback so empty recognition hints still produce a family-specific action hint.

Merge Order

• Ready to merge directly into main: GitHub reports MERGEABLE / CLEAN after the latest branch refresh.
• No prerequisite PR remains open for this branch. The earlier base-family feedback prerequisite has already landed in main.
• Suggested remaining queue: Improve overlay failure hints #59 -> this PR -> Strengthen final floor guidance and ending #63. Local merge-tree simulation confirmed that queue has no content conflicts as of 2026-05-26.

Verification

• Latest GitHub build, test, validate-docs, and codeql checks passed after refreshing the branch.
• Local merge-tree simulation against the remaining open PRs passed without content conflicts.
• Previous Unity EditMode coverage was added for escalation state, assisted-success metadata, fallback hints, and CSV assist fields.
• npm test; Not run locally, Unity-only change.
• npm run build; Not run locally, Unity-only change.

Notes

• Scope: feedback escalation regression coverage, assist metadata assertions, CSV assist-field assertions, and defensive reason-hint fallback.
• Risk notes: this mostly strengthens tests, but the fallback path changes user-facing hint behavior when a recognition result has no explicit hint.
