Cross-Impact And Non-Regression Check

Area	Result
authority count	exactly 27 child authority surfaces; unchanged
runtime evidence	11 physical tables, non-authority, typed #20 object enumeration
retention	hosted in surface #05; no retention table
expected constraints	typed rows inside surface #20; no new table/JSON authority
catalog enforcement	three exact-set families inside catalog root
item payload	descriptive-only; operational reads fail
hashes	H04 evidence dereference/scope and H05/H02 aggregate orders byte-pinned; H01 recomputes transitively; H03/H06/H07 unchanged
index disposition	every extra index fails; a permitted performance index must first become expected through a new sealed #20 manifest version
readiness gates	zero new gates
hash contracts	zero new contracts
Directus	no new authority; sealed read-contract completeness
rollback	new version/append-only; consolidated reverse order
production	READ-ONLY; no live mutation

Required conceptual checks: child/envelope both-EXCEPT; family coverage both-EXCEPT; adapter input edge both-EXCEPT; H01/H02/H04/H05 recompute; CP-06 evidence/scope/total-order fixtures; PG constraint/index both-EXCEPT; extra performance-index failure and expected-set promotion flow; dropped deferred FK fails; runtime negative tests; separation tests; fake retirement evidence rejects; stale/unknown Directus read path blocks.
