Operator phase 2 of the owner-approved 6.65-6.67 release cycle. The physical
mutation lease/holder subsystem was deliberately descoped by the owner:
attribution is evidence-only (root-task baseline, terminal candidate snapshot,
attributed commit staging, projection into acceptance/review evidence, no
structural outcome veto). Ships the surface-aware Python interpreter resolver,
auditable Skill Review rounds/history, the single task-tree disposition
authority with cancel-wins, the SSOT operator review wrapper with typed exit
codes, the parallel hermetic pytest preflight, and the chronic red-CI
light-model test fix.
Review: advisory=skipped (prompt-size cap, non-blocking), triad
fable-5/gpt-5.6-sol/gemini-3.5-flash all responded, scope fable-5 responded,
aggregate PASSED (run 20260716T221730Z, $16.38). Full non-serial+serial pytest
green; ruff -F clean.
