Review follow-up from commit 11df793. Three fixes:
1. Visible semantics: StreamingRegion.Visible now strictly describes the
current (2r+1)×(2r+1) window, not window + hysteresis retainees.
Added a parallel Resident property exposing the actual loaded set
(window + hysteresis buffer). This matters because StreamingController
(next task) reads these to decide what to render vs what to unload;
conflating them in one set would have forced awkward post-processing
downstream.
2. Doc/code disagreement: updated the RecenterTo and RegionDiff doc
comments from "radius + 1" to "radius + 2" to match the actual
implementation (which is what the tests require). Also updated the
plan doc so future readers don't hit the same contradiction.
3. Edge-clamping test coverage: added a single-axis edge test
(cx=0, cy=50 → 15 entries) and an ID-encoding test (radius=0 at
0x12,0x34 → 0x1234FFFE) so a swapped-shift bug in EncodeLandblockId
or an asymmetric off-by-one would fail a test instead of passing
silently.
9 tests green, full suite regressions-free.

9-task TDD plan for the first chunk of Phase A (Foundation): the
streaming landblock loader. Covers StreamingRegion (pure data +
hysteresis diff), LandblockStreamer (background worker + channels),
GpuWorldState (render-thread entity registry), StreamingController
(glue), TerrainRenderer.RemoveLandblock, GameWindow wiring (env var,
camera/player center switch, Dispose), scenery + interior integration,
and the roadmap-shipped-table update.
Each task is a full TDD cycle: failing test, run, minimal impl, run,
commit. ~16 new unit tests land alongside the implementation.
Phase A.2 (frustum culling) and A.3 (net I/O thread) get their own
plans once A.1 ships — they're independent subsystems per the
brainstorming skill's decomposition guidance.

Output of a brainstorming session after Phase 6/7.1/9.1/9.2 shipped
and the lifestone crystal bug was isolated. Two documents:
1. docs/plans/2026-04-11-roadmap.md — strategic roadmap replacing
the stale post-Phase-5 version. Reflects what's actually shipped,
reorganizes upcoming work into Phases A (Foundation), B (Gameplay),
C (Polish — includes VFX/particles, dynamic lights, palette tuning,
double-sided translucents), D (UI + Sound), and E (long-tail).
Updates the "when will my complaint be fixed" quick-lookup with
the correct phase for portals (VFX, not shader tricks as previously
claimed), smoke, fireplace fire, and everything we fixed this
session. Phase ordering: A → B → (C/D in parallel) → E.
2. docs/superpowers/specs/2026-04-11-foundation-phase-design.md —
detailed implementation spec for Phase A only. Covers the four
sub-pieces (streaming landblock loader, frustum culling, net I/O
thread, async dat decoding folded into the streaming worker),
their components, data flow, error handling, testing strategy,
and commit-point ordering. Includes non-goals to prevent scope
creep.
No code changes yet. The spec goes to user review next, then into
the writing-plans skill for a detailed implementation plan.
