Four RR7 variants shipped + reverted in one session (RR7, RR7.1, RR7.2,
RR7.3). The root architectural mismatch: RR7 routed cell-mesh rendering
through ObjectMeshManager / WbDrawDispatcher.Draw(IndoorPass) — a per-
GfxObj batched pipeline. WB uses a separate EnvCellRenderManager (862
LOC) for cells; we never extracted it. Indoor branch fires correctly
after RR7.2 + RR7.3 but interior cell geometry doesn't render.
User direction (verbatim, 2026-05-27): port WB verbatim. No band-aids.
Visual test launch only when fix is ready; probe data verified first.
Handoff captures:
- Session log of all four RR7 attempts + why each failed
- Why WB over retail (modern GL fit + existing Phase N.4/N.5/O
commitment to WB as rendering base)
- The full WB RenderInsideOut algorithm spec (Steps 1-5, line refs)
- 5-phase next-session plan (extract EnvCellRenderManager + deps,
wire into landblock load, replicate RenderInsideOut byte-for-byte,
probe trail mandatory before visual gate, single visual gate)
- Process rules carved from this session's mistakes (no visual gate
without probe data first, no partial WB ports, no conceptual
adaptations, trust-but-verify, slow at brainstorm not implement)
RR3-RR6 infrastructure remains shipped + tested in isolation
(Building/Registry/Loader/Dispatcher cellIds overload/Stencil pipeline).
Branch is at pre-A8 visual ("looks good") with infrastructure dormant.
Next session opens cold against the pickup prompt at the bottom of
the handoff doc.
