Two closed, substantive experiments were missing their DESIGN.md write-up
despite being referenced as prior art by later sections:
- 9o5/xi7/b3v (closed 2026-06-30/07-17): multi-use-leaf type superposition,
a full feature build + real A/B validation (negative — OFF beats ON on
both programme-house and harbor-house) + a veto-hatch follow-up for the
one genuine false-positive interchange class found. §17 and §20 both cite
its verdict directly but it never got its own section.
- mi7 (closed 2026-07-25): 3D bubble-diagram / topological-hop-distance
fitness signal prototype, tested against real evolved trajectories on two
programmes, both formulations null. bubble.py was left in the tree
uncommitted "as documented reference" by the closing session -- committing
it now (with two trivial ruff fixes: unused import, ambiguous var name) so
the reference this write-up makes to it is actually resolvable, plus a
CLAUDE.md module-list entry.
Numbered §26/§27 (appended, not inserted chronologically) to avoid
renumbering every cross-reference in §14-§25.

Python fitness always pins quality_daylight to 1.0 (URB_NO_OCCLUSION semantics),
but oracle.py was invoking urb-fitness.pl without the flag, causing outside leaves
to receive real sun-model daylight scores and producing a ~9% gap.
Changes:
- oracle.py: add URB_NO_OCCLUSION=1 to score_batch env
- oracle.py: Score.fail_lines now parses structured YAML failures from the
llm-agent-mcp branch and converts them to plain-text equivalents, so
parity tests can compare oracle vs native failure sets regardless of format
- Regenerated all 36 corpus .score/.fails files with URB_NO_OCCLUSION=1
(no .score files are tracked in git; the script generates them locally)
- All 183 tests pass; closes homemaker-py-gpx

Two root causes found for ca/cb corpus parity failures:
1. _avg_path_len_from used unweighted BFS (hop count) but Perl's
Graph::average_path_length uses weighted Dijkstra with centroid-to-centroid
edge distances. This caused wrong edge removal in has_circulation, giving
wrong stack corner counts (2 instead of 3 for lr in ca9e80c5).
2. Entrance corner logic used _public_access (any street boundary) but Perl's
Entrances() picks the best entrance route — a stair only gets entrance corners
if no higher-priority non-stair C leaf has public access.
Also includes homemaker-py-hgg storey/building checks previously uncommitted:
stair fit, circ connectivity, roof-garden, public-access tracking, has_circulation,
corners_in_use, stack_corners_in_use, check_space_counts with failure stacking.
All 4 debug corpus prefixes: ratio=1.000000. 39 tests pass.

Clean-room Python successor to Urb for programme-driven layout search.
This initial commit establishes the .dom bridge format and a faithful
port of Urb's top-down quad geometry, validated byte-identical against
Urb across all 35 programme-house example files (including the wall
inset and multi-storey wall-stacking inheritance).
- dom.py: .dom YAML <-> Node tree, parent/below/position linkage,
wall_outer inset on load, raw-corner stash for round-tripping
- geometry.py: Coordinate/Coordinate_a/_b/Area/Length + Coordinate_Offset
- experiments/dump_areas.{py,pl}: geometry regression harness
