Open spans + wall-centric Delete — Implementation Plan

For agentic workers: execute task-by-task; checkboxes track progress.

Goal: Partial virtual wall stretches (space.open_spans) + Delete operates on walls (close → merge/delete room), then ship v1.59.0-beta.6.

Architecture: Pure helpers in src/open-spans.ts; card wires two-click openwall and wall-centric delete; open_to remains the light-zone index derived from spans; legacy open_to-only configs expand to full sharedBoundary on read.

Tech Stack: TypeScript, Lit card, node:test, Playwright smokes, GitHub prerelease.

Spec: docs/superpowers/specs/2026-08-05-open-spans-delete-design.md

Global Constraints

• Cursor openwall = crosshair (not pointer)
• Openings forbidden on virtual; purge on open
• Thickness clear on open; restore neighbour / DRAW_WALL_DEFAULT_CM on close
• Delete: virtual→close; shared→confirm merge whole pair; outer/inside→confirm delete room
• Version bump to 1.59.0-beta.6 for this ship
