2026-07-21 — itd-66 (`launch-payload-render-parity`) is DEFERRED to a follow-up

2026-07-21 — itd-66 (launch-payload-render-parity) is DEFERRED to a follow-up after the derived-versioning + auto-changelog + distribution programme. itd-67's own AC frames its installability smoke as "light … later upgraded to call" itd-66's deep tier, so the split is clean: this programme builds the light tier and positions the surface-resolution seam so itd-66's deep render, .abcd/** leak-proof assertion, symlink resolution, parity diff, and isolated-subprocess deep smoke slot in as a drop-in upgrade rather than a rewrite. Ordering: this programme -> itd-66. Recorded in spc-11's "itd-66 is deferred" section.
