Five reliability-interactions files exercised the same aiMergeTask ->
resolveBranchGroupMergeRouting -> evaluateBranchGroupPromotion triangle,
each paying its own real-git fixture. Removals verified duplicate-by-
duplicate against shared-branch-group-lifecycle (master integration) and
group-merge-coordinator (fast unit coverage of all gate reasons):
- delete branch-group-promotion-gate (all 5 gate scenarios covered elsewhere)
- delete branch-group-promotion (promote-once = lifecycle CASE 3)
- delete shared-group-member-integration; its unique runMaintenance
assertion absorbed into lifecycle CASE 4
- automerge-precedence: drop pause/engine/settings loop (unit-covered);
keep group-level autoMerge override tests (unique)
- merge-routing: drop 2-member + ungrouped routing dups (lifecycle CASEs
2/6); keep worktreePath + dual-audit-event tests (unique)
Inventory diff: 11 removed IDs, all mapping to approved deletions (12th
is the known secrets-crypto randomized-title artifact). Engine
default+reliability: 6516/6516 pass. Affected-file wall-clock 52.9s -> 19.0s.
Skipped: in-process-runtime source-sniff deletion — the audit claim did
not match the actual file (fully-mocked suite, no readFileSync sniffs);
left untouched.
