06 - SUPERTRACK F: Construction-Order Implementability (no-guess)

Lens: a future implementer must be able to execute S00-S19 without inferring any list, order, DDL, role, or grant.

Checks

check result
every step has exact input docs PASS - each S-step cites its source (approved RP-03 order, doc 02 byte DDL, #20/#21/#26/#27, doc 06 guards)
every step has an unambiguous output artifact PASS - DDL/DATA/seed/proof artifacts named per step
every precondition checkable PASS - predecessor S-step + named guard greens
every no-go checkable PASS - each S-step row has a concrete stop condition
every proof concrete PASS - guard names, both-EXCEPT, recomputed hashes, #11 closure
every step marks author-only vs operator-gated PASS - who column splits T1 (author/read-only) vs OP (LIVE/SEAL/ACTIVATE/REVOKE/FREEZE)
no "etc." for load-bearing objects PASS-after-fix - S15/S16 no longer say "apply/writer"/"enumerated ...": both now reference the S00-captured complete legacy control-object set (MB-01)
no "as appropriate" PASS - none found
no inferred list/order/DDL/role/grant PASS-after-fix - the one inferred list (the neutralization/cutover target) is now a catalog-derived sealed set captured at S00, re-validated at PKG-D
every affected hash/readiness/rollback dependency named PASS - regclass/regprocedure binding-order note (XHO-01); #20 before seal; rollback rows per step
S19 precondition correct PASS - S18 (XHO-01); S19 cites the full 30-guard suite

Finding (folded into MB-01)

The only genuine no-guess gap was the neutralization/cutover set being described by adjective ("apply/writer", "enumerated legacy ... control objects"). Fixed under MB-01: S00 now captures the COMPLETE legacy control-object set (catalog-derived from pg_class/pg_proc), and S15 (neutralize), S16 (cutover), and S17 (freeze) all reference that single captured set - so an implementer never has to decide "which functions count." The set is the authority, derived live, not inferred.

Atomicity / coherence (Max-D, see doc 04)

S15 and S16 are now explicitly single atomic operator transactions with guard-verified end states and immediate stub/snapshot rollback, so a partial step cannot strand the system in a half-cutover state an implementer would have to reason about ad hoc.

Verdict

CONSTRUCTION_ORDER_IMPLEMENTABILITY_PASS_AFTER_FIX - S00-S19 are executable from named inputs to named outputs with checkable preconditions/no-gos; the single inferred-list gap is closed by the S00-captured catalog-derived set; nothing load-bearing is left to implementer judgment.
