Gadfly findings on #95: - Correctness (3 models): the shared inset formula radius-spacing/2 collapses to 0 in grid mode (radius = spacing/2), so grid's outer row planted flush on / overhanging the bed edge instead of the half-spacing in that the rule wants. The inset genuinely differs by layout — a grid plant sits AT the plop centre (inset spacing/2), a clump's plants reach its rim (inset radius-spacing/2, overhanging by a half). Split it into a new edgeInset(radius, spacing, layout); hexCenters now takes a precomputed inset and is pure geometry (no spacing/layout knowledge). Regression guard: grid plants land at ±25 on a 60cm bed, not ±30. - Performance (2 findings): the in-loop `existing = append(existing, *p)` was dead — every plop in one fill shares a radius and sits on a distinct lattice point, and a plop is "covered" only when wholly inside another, impossible between equal-radius circles at different centres. Removing it stops the coveredByExisting scan growing during the fill (an empty-bed grid fill's check was needlessly quadratic in the plop count). - Docs: FillRegion/fillLoaded/hexCenters comments and the DESIGN.md bullets updated for plopRadiusFor/edgeInset (were still citing defaultPlopRadius and "written out in hexCenters"). - Test hygiene: split the grid + bad-layout cases out of TestFillAndClearAPI into TestFillLayoutAPI (one concern per test). The enum-tag finding is a non-issue: majordomo's DefineTool derives its arg schema from the same struct-tag reflection as Generate (proven by the vision SeedPacket enum), and the service validates mode regardless.
