Saves the 2026-06-05 Architect positioning pass as competing CANDIDATE options
under the core line's positioning variant group, beside Option A/B: Convergence
(47/60), Access (40), Asymmetry (36), Scarcity/chokepoints (35), Freedom-tech (28),
each with its red-team weakness inline. One-time, additive, non-canonical
(guardrail #4); idempotent via an interaction_log sentinel so a partner-deleted
option is never resurrected. ensure_positioning_framings runs after the v5 seed.
Test: test_positioning_framings.py (count/candidacy/idempotency/no-resurrection/log).
