First GPU pass on the rev-3 depth pipeline surfaced two issues; both fixed
and re-rendered clean:
1. Blown near-field highlights (regression from 018909b). Mapping the
nearest pixel to pure white (nearPlane=nearRaw) made the depth
ControlNet render overexposed near floors/ceilings at strength 0.85.
fpv.js: nearPlane=0 (anchor white at the camera; nearest real surface
≈gray 214, headroom intact) + minSpan 5→8. Re-bake confirms the blown
ceiling is gone while recesses still reach black and geometry holds.
2. Phantom doors on closed walls — a PROMPT problem, not the depth map
(present in old maps too). Opening NOUNS in the positive prompt summon
a passage onto solid stone: threshold's "gatehouse, portcullis,
entrance" painted a gate on a blank wall, and at cfg 1.0 the negative
can't cancel it. bake_atlas.py: THEME_BODY_CLOSED (full theme flavor,
zero opening nouns) for closed facings + opening-nouns negated on
closed facings only. r0_N (threshold) now renders clean ashlar wall.
("Bricked-up archway" backfires — "archway" alone re-summons the arch.)
Also: sweep_strength.py re-exec-under-venv guard (the venv python is a
symlink to the base interpreter, so the realpath check wrongly skipped
the hop and the montage died after every render); now env-sentinel
guarded. Findings in .dev/2026-06-15-diffusion-pipeline-reliability.md.

--alt-work renders each test frame from a second depth dir alongside the
new full-range maps, so the GPU run proves the rev-3 normalization fix
(018909b) beats the washed-out rev-2 maps rather than just looking
better. Persisted the rev-2 maps under tools/out/compare/rev2_depths so
the A/B is reproducible. Doc updated with the one-shot command.
Workstation note: host 192.168.1.26 is up but ComfyUI (:8188) wasn't
running this iteration — needs a manual start before the sweep.

sweep_strength.py renders one open + one closed FPV frame across a
ControlNet strength matrix at fixed seed/prompt and montages them beside
the depth map — the GPU experiment to find the right strength now that
rev-3 depth maps carry a full-range signal (018909b). Findings/plan in
.dev/2026-06-15-diffusion-pipeline-reliability.md.

New sandbox experiment: a deterministic, fully-parameterized real-time
combat engine (EQ/Daggerfall lineage) built on a single combined Vigor pool
(health+endurance+mana) with ceiling/fatigue attrition, capacity-as-fill
stagger cascade, symmetric Actors + pluggable controllers, one composable
Ability model (skills==spells), and classless three-layer emergent identity.
Sim-first: headless deterministic engine + batch sweep harness + CSV/JSON
export for data-driven balancing. Rust engine (combat-core/combat-sim) +
Python analysis layer, in its own decoupled combat/ workspace.

Render actual generated dungeons through the AI pipeline — both top-down and
first-person (Eye-of-the-Beholder style) — instead of synthetic test depth.
All renderer-side: derived from the envelope's tiles+regions+theme, the core
stores none of it.
- depth.js: top-down height-field depth exporter (walls raised, pools recessed,
pillars as bumps, subtle per-theme relief), calibrated to the proven room_depth
levels so one tall room can't crush every floor dark.
- fpv.js: first-person depth via a Wolfenstein-style grid raycaster (16:9),
reports straight-ahead distance for opening detection.
- explore.js: room->room nav graph derived from REAL tile openings (scan
boundary gaps, bin by cardinal, flood the corridor to the destination room) —
nav + open share one source of truth with the rendered passages.
- bake_atlas.py: bakes per-room x4-facing pixel-art frames; per-theme + per-facing
(wall vs passage) prompts, fixed diffusion seed for cross-frame style coherence,
per-run unique prefixes so re-bakes don't silently skip.
- explore.html + explore-viewer.js: WASD first-person dungeon explorer
(room-to-room movement, turning, minimap), integer-pixel fullscreen.
- serve.py: stdlib dev server — static web root + /out tree + POST /save, no-store.
- main.js/render.js/style.css: export hooks, the depth button, distanceToWall export.
- tools/README.md: Stage 0/1/2/3 docs; .dev/2026-06-01-fpv-prompts.md: prompt
research (cfg-1 negatives are inert; trigger words summon hands; empty-ruin
reframe; fixed seed = consistency).
Proven end-to-end on seed 7 (17 rooms). Outputs organized under git-ignored
tools/out/. Control strength: 0.80-0.85 top-down, 0.85 first-person.

Adds the design for a live browser-based dungeon generator: reikhelm-core
compiled to WASM (after dropping the unused rand dep), a thin reikhelm-wasm
bridge, and a vanilla-JS/Canvas atmospheric renderer driven + screenshotted
via Playwright. Plus C2: room shape variety (rect/octagon/ellipse/plus) to
escape rectangular rooms. Aesthetic target: atmospheric + polygonal.
