11 - SUPERTRACK L: Cross-Layer Impact Review

Checks

check	result
birth foundation change does not break governance	PASS - birth gateway DO_NOT_TOUCH; G-BIRTH-NEUTRAL; FIX7 references it only via #26
governance cutover does not break registry truth	PASS - cutover scoped to QT001 control objects; registries are new qt001_cp tables, not a pivot of existing registry-of-record
registry truth does not duplicate Đ43 context truth	PASS-after-fix - XHL-01; explicit OUT-OF-SCOPE boundary added (doc 08 §E)
registries-pivot repoint remains later, not included	PASS-after-fix - new hard-block row + OUT-OF-SCOPE boundary
memory/harness/Đ43 alignment not accidentally skipped if needed later	PASS - listed as future cross-layer step (doc 08 §E), not silently dropped
raw birth not used as managed-object truth	PASS-after-fix - explicit boundary: raw birth = birth-event truth, authority lives in sealed manifests
runtime evidence is not authority	PASS - 11 runtime-evidence non-authority; G-RUNTIME-NONAUTH
lifecycle/death out-of-scope unless noted future	PASS-after-fix - QT-006 lifecycle/death marked BLOCKED_UNTIL_AUTHORITY (design index Stage 5)

Finding

XHL-01 (P2) - missing explicit cross-layer scope boundaries

• The High blueprint addressed the QT001 control-plane refactor well but did not explicitly state that adjacent layers are OUT OF SCOPE. Without this, a future reader could mistake the QT001 control-plane repoint for a broader registry/governance/lifecycle change - or could assume Đ43 context-truth, QT-006 lifecycle, or a registry-of-record pivot are handled here.
• Fix: added doc 08 §E "Cross-layer scope boundaries (explicitly OUT OF SCOPE)": registry-pivot repoint, Đ43 context-truth reconciliation/dedup, QT-006 universal lifecycle/death, raw birth_registry as managed-object truth, memory/harness/Đ43 alignment - each classified and with a why-out-of-scope. Plus the registry-pivot hard-block row in §A.

Cross-impact checked

• The OUT-OF-SCOPE boundaries are consistent with the hard-block list (§A) and the unlock chain (§D): nothing in PKG-A..I touches these layers.
• No invariant affected; this is a scope-clarity addition.

Verdict

CROSS_LAYER_PASS_AFTER_FIX - the refactor is correctly bounded to the QT001 control plane, with adjacent layers (Đ43 context truth, registry-of-record pivot, QT-006 lifecycle, raw-birth-as-truth) explicitly out of scope and blocked.
