{"id":"bd-86","title":"Make two-clone workflow actually work (no hacks)","description":"TestTwoCloneCollision proves beads CANNOT handle two independent clones filing issues simultaneously. This is the basic collaborative workflow and it must work cleanly.\n\nTest location: beads_twoclone_test.go\n\nThe test creates two git clones, both file issues with same ID (test-1), --resolve-collisions remaps clone B's to test-2, but after sync:\n- Clone A has test-1=\"Issue from clone A\", test-2=\"Issue from clone B\" \n- Clone B has test-1=\"Issue from clone B\", test-2=\"Issue from clone A\"\n\nThe TITLES are swapped! Both clones have 2 issues but with opposite title assignments.\n\nWe've tried many fixes (per-project daemons, auto-sync, lamport hashing, precommit hooks) but nothing has made the test pass.\n\nGoal: Make the test pass WITHOUT hacks. The two clones should converge to identical state after sync.","acceptance_criteria":"1. TestTwoCloneCollision passes without EXPECTED FAILURE\n2. Both clones converge to identical issue database\n3.

But it should recognize that test-2 in JSONL is actually ITS OWN issue (content match).\n\nSolution: Add content-based rename detection during import.
