ssz: daylight is required of rooms that do not need it DESIGN.md 38.6 concluded the three crinkliness modes were inert against the circulation-deletion incentive. Two things were wrong with that measurement. Its premise, 38.2, is retracted. And its script selected leaves with the pre-39.4 prefix rule `type[:1].upper() in ("C","O")`, which sweeps every programme room starting with c or o -- cr1, of1 -- in as circulation. The simpler problem is that none of the three modes ever touched the leaves ssz is about. quality_uncrinkliness reaches `if not crink` before any mode logic that matters, so for a zero-exposure leaf: floor returns 0.01 (one percent of a unit quality, multiplied into a product and weighed against a whole leaf's cost -- inert); compact_ok is self-contradictory, announcing that compact is not a defect and then returning the floor for the most compact case of all; exempt_circulation reaches at most a third of them. Measured: 0% / 0% / 0% / 21-33% of buried leaves rescued. What the buried leaves are, now that 39.7 gives every space a usage: two thirds of them are spaces that architecturally do not want a window -- stores, WCs, plant, corridors, covered courtyards -- scored identically with a windowless bedroom. harbor 22/33, maple 33/46, health 9/18. - crinkliness_mode="usage_daylight": daylight required of the uses a person occupies (programme.DAYLIGHT_USAGES) and nothing else. Elsewhere the factor is clipped on the compact side only, so being buried stops being a defect while over-exposure still costs -- a crinkly leaf costs envelope whatever it is used for. A windowless bedroom stays the hard zero it is under stock: 11/11, 13/13, 9/9 still failing. - compact_ok repaired to score the buried limit as compact, the behaviour its name always claimed. It now rescues 100% including bedrooms, and is kept as the upper-bound control, not a candidate. - ab_ssz_search.py: the fixed-budget search A/B ssz's acceptance criteria actually asks for. Every arm is optimised under its own objective and re-scored under stock urb, because the permissive modes return 1.0 where stock fails and would otherwise win by deleting a fail category. - ab_crinkliness_mode_ssz.py: prefix rule fixed, retracted premise flagged in its docstring. - 38.7's remaining claims from the retracted 38.2/38.3 corrected. Default is unchanged ("urb"), byte-identical to all prior runs. Lint at parity (46 pre-existing); tests 366 passed, 10 new, same 7 pre-existing fixture failures (homemaker-py-bdf).
