Per operator (session 0072): every slice must end in a usable deployment and
declare which Part C scenarios it makes pass. Tag all 23 Gherkin scenarios with
@S<n> (the slice that completes them) and re-cut Part E from layer-by-layer
(N1-N6) to usable increments (S1-S6) with a slice->scenario index table. S1
bundles the coupled migration 029 + threading + redirect as one right-sized
first session; S2 second collection; S3 role enforcement; S4 invitation;
S5 create-project + directory; S6 types + SPEC merge.
