Brainstorm assumed all four 23.4-prep commits had shipped to main.
Branch verification (post-iter/23.4 deletion) showed only prep1
(linearity + check bare-name) is on main; prep2 + prep3 were
attempted on the stranded iter/23.4 branch and never landed.
Spec corrections:
- Goal section: prep-commit status block reflects actual main state.
- Architecture: drop §2 (prep2/prep3 rollback) — no rollback exists
on main; section count drops from four to three artefacts.
- Components table: prep2/prep3 row now reads 'abandoned 2026-05-11
with iter/23.4 deletion', not 'shipped, rolled back in 23.4'.
- Acceptance criterion 1: drop the 'prep2 + prep3 are rolled back'
clause.
- Load-bearing assumption 5: now states prep2/prep3 never reached
main (fixes the silent-assumption pattern this spec exists to
prevent — same failure mode the original Spec-23 had).
- Load-bearing assumption 6: cite the cherry-picked main SHAs
(0caaced, 923dd8c) alongside the stranded-branch originals
(8d39f13, aef4ab8).
- Known costs: drop the '23.4 rollback' line item.
