Evidence, restated from the children (#592 for #586, #595 for #594) and the verification on the epic head 74dc7d9:

Review: no blocking findings (#592 round 2 and #595 round 1, both default model)
Journey: session-adopt-unsandboxed PASS on the epic head 74dc7d9, stack r587 with eve ff056b5 (SUMMARY pass=10 fail=0 blocked=0 notrun=2)
Harness weakening: none; session-adopt keeps all its checks and its 240 s timeout, the new journey is additive (#592); #595 changes no harness file
Main harness vs head: main's devboxverify (60f4286) against #586's head 80ce73b on stack r586: SUMMARY pass=9 fail=0 blocked=0 notrun=2 (#592); #595 changes no harness file
Break-and-restore: #592 dropped no_project from the session_adopt args, TestAdoptNoProjectAuditRows and session-adopt-unsandboxed went red, green after restore; #595 restored the bare Headless check in decidePermission, both bug594 tests went red, restored byte for byte
Weakening reviewed: prooftest no_project refusal cases and the e2e no-project expectation replaced by the approved rule change in #585/#586; no assertion loosened
