Adds --report action mode to verify-patch-content.py that implements
the AGENTS.md § 'Orphan-Patch Supersession Decision Tree' algorithmically.
For each orphan, the action recommender outputs one of:
- INTEGRATED: fork log has >5 commits matching topic keywords;
the work IS in the fork under a different commit
subject. Safe to archive as superseded.
- FILE-RESTRUCTURED: target file no longer exists in fork (file
rebased past patch's expectations). Safe to archive.
- NO-TARGET-FILE: patch lacks +++ b/ header (non-actionable).
Safe to archive.
- MISSING-UPSTREAM: work NOT in fork; needs reapply or fork rebase.
Algorithm (in suggest_action_for_orphan):
1. Check if patch has no target file (lacks +++ b/) → NO-TARGET-FILE
2. Check if target file no longer exists in fork → FILE-RESTRUCTURED
3. Run 'git log -i --grep <topic-keyword>' on the fork; if >5 commits
match → INTEGRATED
4. Otherwise → MISSING-UPSTREAM
Validated with synthetic test: created a local/patches/relibc/
_test-synthetic-orphan.patch with target=lib/test/strange.rs (which
doesn't exist in fork). The recommender correctly classified it as
FILE-RESTRUCTURED.
Wired into pre-push-checks.sh as check #3a (verify-patch-content-action).
Future new orphans are auto-classified; the operator only needs to
verify the suggested classification matches reality and then archive
to legacy-superseded-2026-07-12/.
