Brainstorm-approved design for the A8 R3.5 → restructure pivot. Replaces
the R3.5 v1+v2 frankenstein (terrain twice + depth-clear workaround) with
WB's RenderInsideOut order verbatim: skip initial sky+terrain when inside,
delete the depth-clear, add a stencil-gated sky step inside the indoor
branch so windows show real sky (closes R4 Issue B).
Unifies the two-flag asymmetry (cameraInsideCell lenient + cameraReallyInside
strict) into a single strict cameraInside flag via PointInCell. Grace
mechanism in CellVisibility stays alive for non-render consumers.
Six tasks ahead, in order:
RR0 — pre-restructure falsification spike (Issues A + C on main?)
RR1 — revert R3.5 v1+v2 (38d5374 + 2bfeafd)
RR2 — restructure render frame to WB-faithful order
RR3 — verify SkyRenderer doesn't toggle stencil state
RR4 — visual verification matrix (cottage/cellar/inn/dungeon + transitions)
RR5 — ship docs (close#78; file new follow-ups if pre-existing on main)
Next: superpowers:writing-plans to produce the per-task plan.
Note: the design references two predecessor docs that are currently
untracked in this worktree (entity-taxonomy + phase-a8-replan). Their
contents are read-stable on disk; committing them is a separate concern
(they belong to the prior session's work). The handoff doc this design
continues from is at f90fa2f.
