+# HyperTwist Phase 2R-B Subordinate Operational And Phase G Alignment - 2026-05-27
+
+## Status
+
+This document closes the remaining row-source truth gap for the already-closed
+`Phase 2R-B` subordinate permissive rows after the source-audit layer was
+aligned.
+
+It answers one narrow question:
+
+- after the subordinate-stack reconciliation notes and the later source-audit
+  alignment landed, do the `v6.3` operational and `Phase G` rows still speak
+  about these repos like merge-bench or donor-bench activation candidates
+  instead of already-closed bounded sidecars beneath landed anchors
+
+Result:
+
+- yes, the remaining stale layer was the operational and `Phase G` wording
+- the state board, reset lanes, and source-audit layer were already correct
+- the needed fix is operational and `Phase G` alignment only
+- no product code, live ownership, or roadmap routing changed from this pass
+
+## Affected rows
+
+The affected rows are the same `24` subordinate `2R-B` rows already named in:
+
+- `C:\HyperTwist\docs\HYPERTWIST_PHASE2RB_SUBORDINATE_SOURCE_AUDIT_ALIGNMENT_2026-05-27.md`
+- `C:\HyperTwist\docs\HYPERTWIST_BROWSER_SPATIAL_SUPPORT_SUBORDINATE_STACK_SOURCE_TRUTH_RECONCILIATION_2026-05-27.md`
+- `C:\HyperTwist\docs\HYPERTWIST_ANALYTICS_AND_BROWSER_VIEWER_SUBORDINATE_STACK_SOURCE_TRUTH_RECONCILIATION_2026-05-27.md`
+
+## Required operational and Phase G posture
+
+For these rows the remaining source pack must now say:
+
+- the row is already closed as a subordinate sidecar beneath a landed anchor
+- preserve only the bounded retained sidecar slice
+- no default widening packet is open
+- any later reopening must come from narrower anchor-side gap proof only
+- do not describe the row as a generic merge-bench or donor-bench activation
+  candidate
+
+## Alignment rule
+
+For each affected row:
+
+- replace merge-bench or donor-style operational realization language with
+  closed subordinate-sidecar language
+- replace `Phase G` reasons and rationales that still imply generic activation
+  with closed subordinate-sidecar reasons
+- keep current live-state, reset-lane, and historical bucket values unchanged
+
+## Final call
+
+These rows remain intentionally non-live.
+
+They are retained only as closed subordinate sidecars beneath landed anchors,
+and the operational plus `Phase G` row-source layers must now describe them
+that way.
