Topology genome: base tree + per-storey deltas + type assignment
genome.py (homemaker-py-k2g): Genome = base-floor GNode tree + per-storey
StoreyDelta (undivides, divide subtrees, leaf retypes, height) + base
metadata. encode/decode round-trips dom.py Node trees.
Key empirical finding baked into the design: upper-storey nodes carry
heavily drifted DEAD fields (97 inherited-cut divisions, 187 rotations
differ from the owning node below across the corpus) — dead because
geometry delegates to below before reading them. decode canonicalises
them; encode stores only owned state, so genomes from drifted sources
compare equal (fixed-point test).
Acceptance: 35/35 corpus files fitness-identical after round-trip through
the oracle (experiments/genome_parity.py, URB_NO_OCCLUSION=1); owned-cut
projection + genome fixed-point + storey counts in tests/test_genome.py
(16 tests pass).
Closes homemaker-py-k2g.
