Closes the second namespace sharing a first character with programme codes: the usage prefixes b/t/l/k, under which a room silently inherited another room's connectivity rules from its spelling. usage is a plain, MANDATORY attribute of the space definition -- not a lookup table. An interim design proposed a top-level usage_classes: table binding author-coined names to behaviour; withdrawn, because an indirect name->behaviour mapping living apart from the thing it describes is exactly the shape of the prefix rule §39 exists to remove, it would be the only such table in a schema where every other space property is a plain attribute, and the need it served was already met -- "building specific" is about what a room is CALLED, and name: is already free text. Rule that settles it: a usage value exists iff the engine treats it differently somewhere. Config selects among behaviours; it cannot invent them. - programme.USAGES (living/kitchen/bedroom/toilet/utility/none) plus the behaviour groupings PRIVATE_USAGES / PRIVATE_STRIPS / TOILET_STRIPS / SOCIABLE_USAGES. Missing or unknown usage is a load error naming the code, from BOTH parse paths. - Code-level, never leaf-level: usage_of(leaf.type) is looked up fresh, so a retype changes the class automatically. 51 sites assign leaf.type, and share/share_type plus the r5a resurrection are the precedent for why leaf-level attributes rot. - graph.has_circulation takes the usage map and trims on declared class; fitness.access and the public-access check likewise. fitness._t0 is DELETED -- no first-character type test remains anywhere in the codebase. - utility is distinct from bedroom (same access requirements today) because it is a different use and gives derive_interchange_classes an axis to relax on. - A toilet now keeps its edge to a terminal room -- the Brand adjacency, which the old b-before-t loop ordering severed. - All 107 corpus entries migrated by experiments/migrate_usage_key.py, comments and layout preserved. MEASURED -- the connectivity model was ~4x too permissive. `none` is not neutral: nothing is trimmed, so the graph may route THROUGH the room, and 34 of 52 codes had no class (Dental Surgery, Records Room, Utilities Closet all served as corridors). Edges trimmed, prefix-inferred vs declared, 3 seeds each: harbor-house 18 (9%) -> 79 (39%) inaccessible fails 0 -> 4 health-centre 12 (8%) -> 59 (40%) inaccessible fails 2 -> 3 maple-court 53 (17%) -> 123 (39%) inaccessible fails 1 -> 5 Re-baseline (seed 1, 20k, harbor): 58 fails (15h/43s) -> 61 (16h/45s), now reporting 1-inaccessible-usable-space x2 plus level 0 and level 1 not connected. The count rose because the objective got honest -- those failures were always true of the layout and the old model could not see them. Every harbor number before this was measured against a graph crediting routes through store cupboards. Sharpens §38.2: the objective pays x60-85 to delete circulation, and until now the deleted corridors were not missed because storage stood in for them. With that substitution gone, homemaker-py-2v1 is the remaining half -- and now measurable, because the fails it should prevent actually fire. 350 passed (+5 new), same 7 pre-existing fixture failures, lint unchanged.

# Harbor House L0 - single-storey de-risk variant (homemaker-py-c4c.1)
|
|
#
|
|
# Built from harbor-house by retaining ONLY the 10 space codes explicitly
|
|
# marked `level: 0`. The straddling anonymous spaces (n=neighborhood, t=bathroom)
|
|
# carry no explicit level key and are dropped here so the programme is an
|
|
# unambiguous single-storey set. Adjacencies are pruned to the retained codes
|
|
# (all remaining refs are to c/o or to retained codes k1/da1).
|
|
#
|
|
# Purpose: isolate per-floor CONSTRUCTION difficulty from multi-storey COUPLING.
