- math::triangulate_polygon now ear-clips via polygon::triangulate_indices
(index/orientation preserving; rejects degenerate, non-finite, bow-tie)
- extrude_polygon_mesh routes through triangulate_profile; new
try_extrude_polygon_mesh returns structured errors instead of
underflowing on undersized profiles
- tests: concave area equality, closed-manifold edge twins, bad corpus
- cad.yml gate forbids reintroducing the vertex-zero fan
- EXECUTION_PLAN.md: tranche ledger, verification, release gates
CORE-11: parsed scheme/host identity replaces string-prefix trust;
loopback is exactly localhost/127/8/::1; plaintext http only for
loopback; lookalikes, user-info, bad ports, fragments rejected.
CORE-12: resource_limits, format_interop (independent parsers), and
migration_corpus integration targets.
Hygiene for green gates under the pinned toolchain: unused-import
cleanup, derivable Default impls, needless-range/manual-contains
fixes, type aliases, fixture-literal allows (no numeric changes).
CORE-06: DocumentEdit/ScenePatch transactions against base revisions;
failed patches leave byte-identical state, stale bases rejected, undo
via inverse patches, refuse/cascade deletion policy.
CORE-07: one canonical bounded world-mesh stream (hierarchy, full
transforms, inherited visibility, named unit conversion, triangle
budgets, chunked cancellation with no partial success).
CORE-01: CadError with kind/entity-path, ValidationPolicy/GeometryBudget
hard ceilings enforced before allocation, opaque typed ids with checked
supply, explicit remap tables; missing material/layer refs are hard
errors, never silent fallbacks.
CORE-02: identity transform is translation 0/rotation 0/scale 1
(Default no longer collapses to zero scale); single local/world matrix
convention T*Rz*Ry*Rx*S with iterative validation (duplicates, dangling,
cycles, depth 1024) and inherited visibility.
CORE-03: versioned lossless CadDocument with tagged EntityKind, explicit
units, deterministic canonical bytes, future-version quarantine, and
explicit legacy migration warnings.
Verified in worktree at 64ae8d7: cad-core 319 tests green, clippy/fmt clean.
Whole-tree sync: cad-core/cad-ui split sources, nigig-build
construction_frame migration, pdf port progress, mpesa/pay/uikit/doc
updates, workspace members/profiles/lock, CI workflows and reviews.
