+`ABG-P9.1-FOUNDATION-HARNESS-CLEANUP-H2 INVALID: dispatch binding`
+
+H2's HAPI session `1935a0f4-9b16-4607-8f84-8543b8d0904e` returned the exact identity line, then correctly stopped because the Goal bound worktree `p91-test-cleanup-h2` at `b1f76af`, while the session executed in `p91-test-cleanup-h2b` at `f4cf62c`. No product files were read or written. The session was archived and H3 is required with exact manifest/worktree/branch/HEAD agreement.
