Session-end documentation for the issue #100 ship and the visibility-
culling investigation handoff for the next session.
Three documents land together:
- docs/superpowers/plans/2026-05-25-issue-100-terrain-cutout.md
(the 3-task plan that drove this session's f48c74a / a64e6f2 /
84e3b72 — never committed by Tasks 1-2)
- docs/research/2026-05-25-issue-100-terrain-cutout-handoff.md
(the predecessor session's smoking-gun research that drove the
#100 fix — never committed by the prior session)
- docs/research/2026-05-25-issue-100-shipped-and-culling-handoff.md
(THIS session's handoff: what shipped, what visual-verification
surfaced, the issue family map for #78 + #95 + the new cellar-
stairs finding, root-cause hypothesis, retail anchors, WB
references, do-not-retry list, and pickup prompt for the next
session's investigation + plan + implementation)
Plus two updates to existing files:
- CLAUDE.md — adds a ship paragraph for #100 to the M1.5 progress
block. References the new handoff doc as the next-session pickup
point.
- docs/ISSUES.md #78 — broadens scope from "outdoor stabs visible
through floor" to "outdoor stabs + terrain mesh visible inside
EnvCells". Adds the 2026-05-25 cellar-stairs evidence (per user
direction: not filed as new issue; treated as evidence
reinforcing #78's hypothesis #2). Promotes hypothesis #2 to
"high confidence as of 2026-05-25" and adds the retail anchor
(acclient_2013_pseudo_c.txt:311397 CEnvCell::find_visible_child_cell).
Acceptance criteria broadened to include the cellar-stairs case.
Next session: pickup prompt at the bottom of the new handoff doc
drives a /investigate → writing-plans → subagent-driven-development
pass on indoor-cell visibility culling — the work that closes#78
+ cellar-stairs together, and possibly #95 if the infrastructure
overlaps.
