Introduce a new Quake3 pickups draw workflow step to render in-world pickup icons and register it: add WorkflowQ3PickupsDrawStep (header + implementation), register the step in WorkflowRegistrar, and include the source in CMakeLists. Update the q3_frame workflow JSON to insert a draw_pickups node into the frame graph. Enhance the overlay to show weapon damage in the HUD and draw weapon/hit visuals, and update weapon logic to mark hits and accumulate damage (q3.last_shot_hit, q3.hit_marker_until_frame, q3.damage_done). Also fix trailing newline in CMakeUserPresets.json.
- overlay.fps: SDL software renderer → GPU texture quad, top-right corner,
yellow EMA-smoothed FPS counter; LOADOP_LOAD preserves scene beneath it
- debug.screenshot: one-shot step that writes status txt + BMP then pushes
SDL_EVENT_QUIT for automated visual feedback loop
- Adaptive vsync: graphics.gpu.init "auto" present_mode queries actual monitor
refresh rate via SDL_GetCurrentDisplayMode; ≥120 Hz → VSYNC, <120 Hz → MAILBOX
Fixes vsync cap on 165/170 Hz monitors reporting as 240 Hz in settings
- Fixed present_mode wiring: q3_game.json gpu_init_viewport node now passes
present_mode as a direct parameter (workflow variables are not seeded into
context by the executor, so the variable section was dead data)
- Stair climbing: probeReach 0.45→0.70 for earlier detection, jam detection
nudges player up after 100 ms of horizontal blockage, step_height tuned to 0.6
- Physics dt: real wall-clock delta clamped to [1/600, 1/30] so 240 Hz displays
don't run physics 4× faster than intended
- GUI smart search paths: _candidate_build_dirs() scans all generator dirs ×
build types × flat and Conan-nested layouts, sorted by CMakeCache.txt mtime;
_find_binary() picks freshest sdl3_app.exe; packages loaded relative to
__file__ so gui works from any working directory

Replace held-jump-extends-height (Mario-style) with a Q3-style impulse
jump: set vel.y once on press, gravity does the rest. Apply per-player
gravity scaling symmetrically in air (rising and falling) so jumps don't
feel floaty going up but heavy coming down.
Tune q3_frame for a fun, floaty feel rather than authentic Q3 numbers:
gravity_scale 0.55 (≈55% Earth) + jump_velocity 5.5 → ~2.8m apex,
~2s airtime. Trades rocket-dodge utility for hang-time enjoyment.

physics.fps.move was directly setting linearVelocity each frame on the
ground, producing the classic "no inertia" snap-stop feel. Replace with
a CalcFriction-style ramp: velocity accelerates toward target by
ground_accel * dt, decelerates to zero by ground_friction * dt when
input is released.
Tune the quake3 frame loop to match a modern shooter rather than vanilla
Q3 arcade speeds:
- walk 4.5 m/s (was 8.0 — ~30 km/h is a sprint, not a walk)
- sprint 1.5x (was 2.0x — 6.75 m/s top speed)
- jump 0.9m / 0.22s (was 2.0m / 0.4s — Halo-ish hop, not a moon jump)
- air control 0.15 (was 0.5 — less floaty mid-jump)
- gravity_scale 1.6 (was 0.3 — was actually pushing the player UP
when falling because of how the (gravityScale - 1.0) extra-force
multiplier worked)
Defaults for the new ground_accel (35) / ground_friction (30) params
keep other workflows that use physics.fps.move feeling snappy without
having to update them.

Quake 3 package was missing GPU shaders entirely. With these in place,
the engine boots quake3 successfully: pak0 loads, BSP parses, lightmap
atlas and geometry build, and shaders compile/bind correctly on the
Vulkan path.
bsp.vert: matches BspRenderVertex layout (position/uv/lmuv/normal) and
re-uses the existing VertexUniformData uniform block from the seed
pipeline so no C++ changes are needed.
bsp.frag: classic Q3 model — albedo × lightmap × overbright + ambient.
Skips PBR / shadow mapping entirely; Q3's baked lightmaps already encode
direct + bounce lighting and shadowing. Q3 shader-script effects
(animated sky, scrolling water, env-mapped chrome) render flat — adding
them is a follow-up.
SPIR-V only for now (Windows/Vulkan/D3D12 via SDL3 cross-compile). MSL
and DXIL still missing for Mac/native-D3D12 paths.

Workflow JSON params can now reference environment variables (e.g.
${env:QUAKE3_PAK0}) which are expanded at JSON load time. A new Python
detector reads the Windows registry and parses libraryfolders.vdf to
locate Steam libraries, then resolves known-game files into env vars
that dev_commands.py exports before launching the engine. Lets users
with legitimate Steam-owned game data run packages like quake3 without
hardcoded paths.
Also fixes os.execv on Windows (Invalid argument with spaced paths) by
falling back to subprocess.call.

When Conan's build output layout changes (e.g. build/generators/ vs
build/Release/generators/), CMakeUserPresets.json accumulates includes
that define the same preset names, causing CMake to fail with
"Duplicate preset". The fix detects preset name collisions across
included files and keeps only the newest, in addition to pruning
missing files.

Searches PATH, interpreter/user Scripts dirs, site-packages sibling
dirs, and falls back to module invocation. Covers system Python,
Homebrew, Windows Store Python, pyenv, conda, pip --user, and venvs.

Windows Store Python installs packages without adding Scripts to PATH,
causing FileNotFoundError when invoking conan directly.

Fix CW→CCW winding bug on polygon/mesh faces (types 1,3) that caused
backface culling to discard half the geometry. Decompose the monolithic
bsp.load step (1028 lines) into atomic workflow steps chainable via
JSON connections — each step only runs when connected:
- bsp.load: open pk3, read + validate BSP, store raw data in context
- bsp.lightmap_atlas: build lightmap atlas, upload to GPU
- bsp.parse_spawn: parse entity lump for spawn point
- bsp.build_geometry: build face geometry with CW→CCW winding fix
- bsp.extract_textures: load textures from pk3 with mipmaps
- bsp.upload_geometry: upload merged VB/IB to GPU
- bsp.build_collision: create Bullet physics convex hull collision
Shared BSP structs extracted to bsp_types.hpp. Workflow JSON updated
to chain: load → lightmap → geometry → textures → upload → collision → spawn.

Remove stale dirs/files superseded by metabuilder-small's reorganization:
- Old YAML entity/seed files (migrated to JSON)
- Root-level workflowui/ (moved to frontends/workflowui/)
- Prisma, Pyodide, old hooks, bun.lock artifacts
- Legacy scratch docs (txt/, docs/, deployment/*.md)
- Stale CI workflows consolidated in small

Moves 45 documentation files from centralized /docs/ to subproject directories
following proximity-based organization principle. All moves use git mv to preserve history.
Changes:
- workflow/ docs: Move 27 files from docs/workflow/ to workflow/docs/
- DAG executor docs, workflow compliance, executor analysis, loaderv2 guides, etc.
- Result: workflow/docs/ now has 27 files
- dbal/ docs: Move 11 files from docs/dbal/ to dbal/docs/
- DBAL architecture, analysis, integration, and workflow integration docs
- Result: dbal/docs/ now has 18 files (11 new + 7 pre-existing)
- gameengine/ docs: Move 7 files from docs/gameengine/ to gameengine/docs/
- GameEngine compliance audits, packages, Quake3, soundboard, engine tester
- Result: gameengine/docs/ now has 20 files (7 new + 13 pre-existing)
Benefits:
- Docs are now closer to their code (easier to keep in sync)
- Reduces /docs/ clutter
- Establishes pattern for per-subproject documentation
- All git history preserved via git mv
Next phases:
- Phase 2: Move package-specific docs to /packages/{id}/docs/
- Phase 3: Separate N8N compliance docs by scope
- Phase 4: Organize UI documentation
- Phase 5: Create cross-project indices
