+# Building ps2gl with CMake
+
+This document describes how to build ps2gl using CMake instead of the traditional Makefile.
+
+## Prerequisites
+
+- PS2DEV environment installed and configured
+- `PS2DEV` environment variable set
+- CMake 3.13 or later
+- VU1 development tools (optional - see note below):
+  - **Open-source tools (recommended):** `openvcl`, `masp`, `dvp-as`
+  - **Proprietary tools (legacy):** `vcl`, `gasp`, `dvp-as`
+
+**Note:**
+- VU1 tools are only required for building VU1 renderers from source
+- The build automatically detects and prefers open-source tools (`openvcl` + `masp`) over proprietary ones (`vcl` + `gasp`)
+- If VU1 tools are not available (e.g., on macOS), the build will automatically use pre-built `.vo` object files from the `vu1/` directory
+- Pre-built objects can be generated by running the build once with VU1 tools available
+- **OpenVCL compatibility**: all 13 renderers (including `indexed` and `scei`) now compile successfully with `openvcl` + `masp`. The proprietary `vcl` + `gasp` toolchain remains supported as a fallback, but is no longer required.
+
+## Building
+
+### Basic Build
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+```
+
+### Debug Build
+
+To enable debug symbols and `_DEBUG` definition:
+
+```bash
+cmake -DDEBUG=ON ..
+make
+```
+
+### Building with Tests
+
+To build the test executables (when available):
+
+```bash
+cmake -DBUILD_TESTS=ON ..
+make
+```
+
+## Installing
+
+To install the library and headers to `$PS2SDK/ports`:
+
+```bash
+make install
+```
+
+This will:
+- Install `libps2gl.a` to `$PS2SDK/ports/lib/`
+- Install GL headers to `$PS2SDK/ports/include/GL/`
+- Install ps2gl headers to `$PS2SDK/ports/include/ps2gl/`
+
+## Configuration Options
+
+The following CMake options are available:
+
+| Option | Default | Description |
+|--------|---------|-------------|
+| `DEBUG` | OFF | Enable debug build with `_DEBUG` definition |
+| `BUILD_TESTS` | OFF | Build test executables |
+| `BUILD_EXAMPLES` | OFF | Build the example ELFs under `examples/` |
+| `BUILD_GLUT` | ON | Build the GLUT-compat library |
+| `PS2GL_USE_SCE_VSM` | OFF | Bypass the .vcl pipeline; assemble Sony's reference VSMs (`vu1/sce_<X>_vcl.vsm`) directly with `dvp-as`. Diagnostic mode: lets us isolate "openvcl produces wrong VSMs" from "ps2gl host-side bug" by comparing the SCE-built ELF behavior against the openvcl-built one. |
+
+## Build Flags
+
+The CMake build automatically applies the following flags:
+
+- `-DNO_VU0_VECTORS` - Disables VU0 vector code (currently broken)
+- `-DNO_ASM` - Disables assembly optimizations
+- `-Wno-strict-aliasing` - Suppresses strict aliasing warnings
+- `-Wno-conversion-null` - Suppresses conversion null warnings
+
+## VU1 Renderer Pipeline
+
+ps2gl includes VU1 assembly renderers that go through a complex preprocessing pipeline:
+
+1. **Step 1**: Remove C preprocessor directives and fix include paths
+2. **Step 2**: `gasp`/`masp` assembler preprocessing
+3. **Step 3**: Array notation conversion
+4. **Step 4**: C preprocessor with memory layout headers
+5. **Step 5**: `vcl`/`openvcl` compiler generates `.vsm` files
+6. **Step 6**: `dvp-as` assembler generates `.vo` object files
+
+The CMake build handles all these steps automatically for all 13 renderers:
+
+- fast_nolights, fast
+- general, general_quad, general_tri
+- general_nospec, general_nospec_quad, general_nospec_tri
+- general_pv_diff, general_pv_diff_quad, general_pv_diff_tri
+- indexed
+- scei
+
+All 13 build with either `openvcl + masp` (preferred) or `vcl + gasp` (legacy
+fallback). The output `.vsm` from the open pipeline can be compared against
+the in-tree Sony reference (`vu1/sce_*_vcl.vsm`) for validation.
+
+## CMake Toolchain
+
+The build uses the PS2DEV CMake toolchain file located at:
+```
+$PS2DEV/share/ps2dev.cmake
+```
+
+This toolchain file is automatically detected when `PS2DEV` is set.
+
+## Clean Build
+
+To perform a clean build:
+
+```bash
+rm -rf build
+mkdir build
+cd build
+cmake ..
+make
+```
+
+## Comparison with Makefile Build
+
+The CMake build produces the same output as the traditional Makefile:
+- Same compiler flags
+- Same source files
+- Same VU1 preprocessing pipeline
+- Same install locations
+- Compatible library format
+
+## Migration Notes
+
+The CMake build system was designed to be compatible with the existing Makefile build. Both build systems can coexist in the repository.
+
+### Key Differences:
+
+1. **Out-of-source builds**: CMake uses a separate `build/` directory
+2. **Dependency tracking**: CMake automatically handles dependencies
+3. **Parallel VU1 processing**: CMake can process multiple VU1 renderers in parallel
+4. **Cross-platform**: CMake can generate build files for different build systems
+
+## Troubleshooting
+
+### PS2DEV not found
+
+If you get an error about PS2DEV not being set:
+
+```bash
+export PS2DEV=/path/to/ps2dev
+export PS2SDK=$PS2DEV/ps2sdk
+```
+
+### Toolchain file not found
+
+Make sure the toolchain file exists at `$PS2DEV/share/ps2dev.cmake`.
+
+### VU1 tools not found
+
+Make sure the VU1 tools are in your PATH. For open-source tools:
+
+```bash
+which openvcl masp dvp-as
+```
+
+Or for proprietary tools:
+
+```bash
+which vcl gasp dvp-as
+```
+
+The `dvp-as` tool should be installed as part of PS2DEV. For `openvcl` and `masp`:
+- openvcl: https://github.com/ps2dev/openvcl
+- masp: https://github.com/AzagraMac/masp
+
+### Build errors
+
+Try a clean build:
+
+```bash
+rm -rf build
+mkdir build
+cd build
+cmake ..
+make
+```
+
+### VU1 preprocessing errors
+
+If VU1 preprocessing fails, check that:
+1. All `.vcl` source files exist in `vu1/`
+2. Memory layout headers exist: `vu1/vu1_mem_linear.h` and `vu1/vu1_mem_indexed.h`
+3. VU1 tools are properly installed

+# PS2 OpenGL Toolchain — Current State & Plan
+
+_Last reviewed: 2026-05-12_
+
+## 0. TL;DR — pick this up here next session
+
+**Where we are.** The open pipeline (`openvcl + masp + dvp-as`) builds all
+13 ps2gl renderers and produces ELFs that boot in PCSX2. Both triangle-
+and quad-based samples render correctly. ✅ The GL_QUADS bug is **FIXED**
+(`openvcl@520766b`).
+
+**Headline open items, in priority order:**
+
+1. ~~🔴 **Quad-renderer bug**~~ — ✅ **FIXED 2026-05-12** (`openvcl@520766b`).
+   Root cause: the `CLIP` operand template had `:write` on its first VF
+   argument, copy-pasted from the destination-writing FMAC ops (ADD, MUL,
+   etc.).  But clipw's first VF is hardware-semantically a source — only
+   the CLIP register itself is written.  The bogus `:write` caused
+   openvcl's register allocator to treat clipw as starting a new
+   lifetime, breaking the data-flow chain from the preceding mul.  For
+   v3 of every quad-strip iteration, the allocator gave the mul one VF
+   and the clipw a different freed-up VF (which still held the pre-mul
+   xformed_vert_3 at magnitude ~3.7M after perspective divide).
+   `clipw` correctly flagged that as out-of-frustum, fcand returned
+   non-zero clip flags, and every quad rendered as ADC=skip.  One-char
+   fix (drop `:write`) in `src/Parser.cpp`.  See §2.1.
+2. 🟡 **Dual-pipe scheduler** in openvcl — adjacent-pairing landed
+   2026-05-12 (`openvcl@fd7cf6e`).  Full software-pipelining still
+   future work; the current pass handles only adjacent pair candidates
+   and doesn't hoist instructions across non-adjacent positions.
+   Currently openvcl produces 0.34-0.73× Sony's instruction count per
+   renderer; adjacent pairing closes some of that gap, the rest needs
+   PRO/MAIN/EPI loop restructuring.  Multi-week.  See §2.2.
+3. 🟡 **masp polish** — most of §2.3 closed 2026-05-11: FIXMEs in
+   `src/macro.c` rewritten as NOTEs, stale `build_ps2/` removed.
+   Remaining: README expand, and the dormant `change_base` trailing-`'`
+   bug discovered during test densification. See §2.3.
+4. 🟡 **More unit tests** for masp + openvcl, especially per-module coverage.
+   masp side: sb / hash / number-prefix landed 2026-05-11 (3 new test
+   binaries, 57 cases). openvcl side: 17 → 56 cases — tokenizer suite
+   (`openvcl@edc5b76`) + Parser operand-family / error-recovery suite
+   (`openvcl@acc1ba6`) + RA uninit-read propagation fix and its
+   regression test (`openvcl@66b4486`) all landed 2026-05-11. See §2.4.
+
+**Workarounds & infrastructure landed this session:**
+- `-DPS2GL_USE_SCE_VSM=ON` — bypasses openvcl, assembles Sony's reference VSMs
+  directly. Diagnostic + temporary workaround. (`ps2gl@cmake` commit `316cd91`)
+- `vsm_diff.py` semantic diff harness + per-renderer CTest entries. All 12
+  WILL_FAIL today; XPASS-flips as renderers converge. (`ps2gl@cmake` commit
+  `9138e1f`)
+- openvcl unit + integration test framework. 56 tests (17 originally,
+  +25 from the Tokenizer suite, +13 from the Parser family/error suite,
+  +1 regression for the RA uninit-read propagation fix), 0 failures.
+  (`openvcl@ps2gl` commits `7f1db90`, `de7f1f8`, `bec6b7f`, `edc5b76`,
+  `acc1ba6`, `66b4486`)

+pipeline so any homebrew developer can build ps2gl from source with **only
+open-source** tooling.

+
+## 2. Open work
+
+### 2.1 Quad-renderer rendering bug ✅ FIXED 2026-05-12
+
+**Resolution.** Root cause was the `CLIP` operand template in openvcl's
+`src/Parser.cpp` having `:write` on its first VF argument, copied from
+the destination-writing FMAC ops (ADD, MUL, etc.).  But clipw's first
+VF is hardware-semantically a source — only the CLIP register itself
+is written.  The bogus `:write` flag caused openvcl's register
+allocator to treat clipw as starting a new lifetime, breaking the
+data-flow chain from the preceding mul that produces what clipw
+consumes.  One-char fix (drop `:write`) in `openvcl@520766b`.
+
+For the full historical investigation breadcrumbs see
+`memory/project_quad_bug_investigation_notes.md` — many plausible-
+looking hypotheses (alias collision, clipw→fcand latency, mfir.w → sq
+latency, cross-iteration CLIP leak, software-pipelining-required) were
+all falsified before the correct root cause was found.  Each of those
+hypothesis ruled-out lines remains documented in the notes file so the
+next investigator doesn't re-tread them.
+
+Verified after fix: `nehe_lesson04` and `nehe_lesson05` render both
+their pyramids AND their cubes; lesson02/03 still render triangles;
+GIF chain W field at `0x1100D42C`/`D45C` flips from `00 80 FF FF`
+(skip) to `FF 7F 00 00` (draw) for the previously-buggy vertices.
+
+### 2.1.1 Quad-renderer bug — historical investigation (pre-fix)
+
+(Retained for reference.)
+
+**Symptom.** Any ps2gl example that draws with `GL_QUADS` renders blank.
+`box` shows only the clear color; `nehe_lesson04`/`05` show their triangles
+but not their quads. Triangle-only samples (`lesson02`/`03`) render
+correctly.
+
+**Localized cause.** openvcl writes the wrong ADC bit on vertices 3 and 4 of
+each quad. Captured via PCSX2 memory dump at `0x1100D420` and `0x1100D450`:
+
+| Vertex | Sony (works) W field | openvcl (broken) W field |
+|--------|----------------------|--------------------------|
+| v1     | `00 80 FF FF` (skip) | `00 80 FF FF` (skip)     |
+| v2     | `00 80 FF FF` (skip) | `00 80 FF FF` (skip)     |
+| **v3** | **`FF 7F 00 00` (draw)** | **`00 80 FF FF` (skip)** ❌ |
+| **v4** | **`FF 7F 00 00` (draw)** | **`00 80 FF FF` (skip)** ❌ |
+
+All 4 vertices end up tagged "skip drawing" → GS draws nothing.
+
+**Where the wrong value comes from.** The source's `ior new_adc_bit, vi01,
+z_sign; iaddiu new_adc_bit, new_adc_bit, 0x7fff` chain ends up with
+`new_adc_bit = 0x8000` for in-frustum vertices. The z_sign side is silenced
+(z_sign_mask in VI05 is loaded as 0 by `ilw.w`), so the bug is purely on the
+`vi01` side -- `fcand` is returning non-zero clip flags for vertices that
+should pass clipping. Either openvcl's `clipw.xyz` sequence is producing
+non-zero CLIP entries for in-frustum vertices, or `fcand` is reading a stale
+entry from before the current iteration.
+
+**Workaround.** `cmake -DPS2GL_USE_SCE_VSM=ON` — bypasses openvcl,
+assembles Sony's reference VSMs directly. All examples render correctly
+with this on.
+
+**Status.** Bisected to baseline (`e407703`); **not** a regression from any
+of the recent openvcl work (`bc41a56` / `303c528` / `41dff12` / `5c0227b` /
+`a2a7d9d`). Filed in `openvcl/TODO` (commit `c6e82f5`). Minimal repro at
+`openvcl/test/repro/quad_adc_bug.vcl` (commit `07a3196`).
+
+**To make progress next:** single-step the minimal repro in PCSX2's
+debugger (or run a hand-built "known-correct" reference VSM through PCSX2
+side-by-side and compare CLIP register state cycle-by-cycle). Use the
+repro to bisect which clipw / scheduling decision is wrong; tweak,
+rebuild, re-emit (sub-second turnaround).
+
+### 2.2 Dual-pipe instruction scheduler 🟡
+
+VU1 issues two instructions per cycle: one upper-pipe (FMAC) + one
+lower-pipe (LSU / integer / branch). Sony's vcl reorders independent
+instructions to fill both pipes. openvcl currently emits NOP on the free
+pipe most of the time.
+
+**Concrete evidence:**
+```
+# Sony   vu1/sce_general_vcl.vsm  — one source word, both pipes filled
+addi.xy  VF05, VF00, I            loi  0x45000000
+
+# openvcl  build-test/vu1/general_vcl.vsm  — two source words, lots of NOPs
+nop                                loi  0x44fff000
+addi.xy  VF05, VF00, i             nop
+```
+
+Sony's `general.vsm` has ~22 instructions per main loop; openvcl's ~39 —
+**roughly a 2× VU1 throughput regression**. Per-renderer ratios captured
+2026-05-11 (instr count: openvcl / Sony):
+
+| Renderer              | Ratio | Renderer             | Ratio |
+| --------------------- | ----- | -------------------- | ----- |
+| fast_nolights         | 0.72  | general_pv_diff      | 0.37  |
+| fast                  | 0.73  | general_quad         | 0.34  |
+| general_nospec_quad   | 0.38  | general_tri          | 0.38  |
+| general_nospec_tri    | 0.46  | general              | 0.38  |
+| general_nospec        | 0.45  | indexed              | 0.34  |
+| general_pv_diff_quad  | 0.39  |                      |       |
+| general_pv_diff_tri   | 0.38  |                      |       |
+
+**Status of the rescheduler in code:**
+- `src/Token.h` already has a `PREORDERED` flag (= "do not reschedule") —
+  the hook exists, the pass doesn't.
+- `Dependency.{cpp,h,inl}` looks like scaffolding for the eventual scheduler.
+- README explicitly lists rescheduling as future work.
+
+**Sub-steps when this work starts:**
+1. Read all `vu1/sce_*.vsm` to characterise Sony's pairing patterns
+   (learning pass before coding).
+2. Audit `Dependency.{cpp,h,inl}` — what dep info is already captured?
+3. Add a list-scheduler between code-gen and emission: topological order
+   by data deps, greedy pair upper+lower per cycle, respect VU1 hazard
+   rules (RAW latency on FMAC X/Y/Z/W, FDIV/EFU long-latency pipes,
+   branch-delay slot).
+4. Respect the existing `PREORDERED` flag on tokens that must stay put
+   (branches, XGKICK, FCSET / FCAND control-flow ops).
+5. Re-run `vsm_diff.py`; iterate until openvcl-vs-Sony ratio is within
+   ~10 % on all 13 renderers.
+
+**Risks worth flagging up front:** branch-delay slot, XGKICK timing,
+FDIV/EFU long pipes, and `fcand` register liveness are where Sony's tool
+will be subtly cleverer.

+2026-05-11). Pattern links source files into a test binary so
+per-module tests are easy. Targets:
+
+| Module                   | What to cover | Status |
+| ------------------------ | ------------- | ------ |
+| `sb.c` (string buffer)   | append / reset / grow / overflow / null handling | ✅ 18 cases in `test_sb` (masp@`607196e`) |
+| `hash.c` (hash table)    | insert / lookup / delete / collision / resize    | ✅ 14 cases in `test_hash` (masp@`607196e`) — exercises key-copy ownership and the move-to-front cache over 5000 keys |
+| Number-prefix parser     | `0b` / `0q` / `0h` / `0d` / `0a` vs GASP `B'…`   | ✅ 25 cases in `test_number_prefix` (masp@`816b4d8`) covering `is_base`, `sb_strtol`, `change_base`, `change_base2` |
+| `macro.c`                | macro defs, recursive expansion, comma-arg splitting | open |
+| Directive prefix         | `-P/--prefixchar` default `\`, conflicts        | open |
+| Mode switching           | `\masp` / `\gasp` toggles, nested ifmode         | open |
+| Conditional assembly     | `\ifmode` / `\ifm` / `\endifm` truth tables      | open |
+| Golden files             | Re-run every `ps2gl/vu1/*.vcl` through masp; compare to checked-in expected output | open |
+
+**openvcl** — has 56 tests across `unit/` and `integration/` (was 17
+before 2026-05-11). Hand-rolled harness in `test/include/test_harness.h`
+(TEST_CASE / CHECK / REQUIRE / EXPECTED_FAIL, auto-registered via
+static init). Subprocess runner in `test/include/openvcl_runner.h` for
+end-to-end checks. Targets to expand:
+
+| Area                                              | Effort | Status |
+| ------------------------------------------------- | ------ | ------ |
+| Tokenizer: comments, fields, bit-flags, labels    | ½ day  | ✅ 25 cases in `test_tokenizer.cpp` (`openvcl@edc5b76`) — case-insensitive mnemonic lookup and `.xyzw`→0 normalisation pinned with comments |
+| Tokenizer: argument-list parsing for FMAC/LSU forms | ½ day  | partial — broadcast (`MULw`), post-inc (`(vi++)`) and `imm(vi)` addressing covered by Parser family tests (`openvcl@acc1ba6`); still open: pre-dec, `i`/`q`/`p`/`r` immediate operands, indirect `(vi)` zero-form |
+| Parser: operand templates, error recovery         | ½ day  | ✅ 13 cases in `test_parser_families.cpp` (`openvcl@acc1ba6`) — one positive per VU family (FMAC, FDIV, LSU, IALU, BRU, RANDU, EFU) + negatives for unknown mnemonic, wrong arg count, out-of-range register, family mismatch |
+| Expression: edge cases (some landed)              | started | partial |
+| CodeGenerator golden files per mnemonic family    | 1 day  | open  |
+| CommandLine: every flag in README                 | ½ day  | open  |
+| Scheduler dependency-matrix suite                 | open until §2.2 lands | n/a |
+
+### 2.5 ps2gl hygiene 🟢 (low priority)
+
+- Legacy `Makefile` still present alongside CMake — decide keep-or-delete.
+- `examples/tricked_out/billboard_renderer.vcl` exists but the build
+  links the pre-built `_vcl.vsm`, skipping openvcl on this app-level
+  shader. Wire it through the full pipeline once the quad bug is fixed
+  (tricked_out uses GL_QUADS-like billboard rendering).
+- Add CI that runs `ctest -L vsm-diff` so renderer regressions surface
+  in PRs.
+- Once openvcl reaches parity, drop the `TEMP: Sony reference VSMs`
+  commit via `git rebase -i` (the `vu1/sce_*_vcl.vsm` files were
+  committed as ground truth and are marked temporary in their commit
+  message).
+
+---
+
+## 3. What landed this session (2026-05-11)
+
+All pushed to `fjtrujy/openvcl@ps2gl` and `ps2dev/ps2gl@cmake`.
+
+| Repo    | Commit     | Description |
+| ------- | ---------- | ----------- |
+| openvcl | `bc41a56`  | LOI IEEE-754 hex + expression-evaluated address offsets + SCE-matching VSM header |
+| openvcl | `303c528`  | Loop-body live-range extension in the register allocator |
+| openvcl | `f8b3ff2`  | examples Makefile parallel-build targets |
+| openvcl | `41dff12`  | Defensive checks + stable token pointer in RA |
+| openvcl | `7f1db90`  | Bootstrap unit-test framework (CMake + in-tree harness) |
+| openvcl | `de7f1f8`  | Integration subprocess runner + 2 TODO tests pinned |
+| openvcl | `5c0227b`  | Error::HasErrors propagation into exit code (fixes silent CLIP) |
+| openvcl | `a2a7d9d`  | `.init_vf`/`.init_vi` register-range shorthand (`vfXX-vfYY`) |
+| openvcl | `bec6b7f`  | LOI hex regression tests + Expression edge tests |
+| openvcl | `c6e82f5`  | File the ps2gl quad-renderer bug in TODO |
+| openvcl | `07a3196`  | `test/repro/quad_adc_bug.vcl` minimal repro |
+| ps2gl   | `b74d303`  | TEMP: add Sony reference VSMs (12 files, ground truth) |
+| ps2gl   | `a4c5e06`  | Docs + dead code: all 13 renderers build with openvcl+masp |
+| ps2gl   | `9138e1f`  | Semantic VSM-diff CTest harness (`vsm_diff.py` + 12 entries) |
+| ps2gl   | `316cd91`  | `PS2GL_USE_SCE_VSM` diagnostic build option (quad-bug workaround) |
+
+**Closed openvcl TODO items:** 4 of 6 — LOI hex, line-based register
+allocator, CLIP validation, `.init_vf` range. All with regression tests.
+
+**Open openvcl TODO items:**
+- Output-parameters only applied at "proper" branch exits (vague spec)
+- GASP preparsing doesn't track filenames (low priority)
+- *Plus the new quad-renderer bug* — filed, repro committed.
+- ~~**Error propagation gap** for RegisterAllocator uninit-register
+  reads~~ — ✅ fixed 2026-05-11 (`openvcl@66b4486`).  The seven RA
+  paths (`float/integer/accumulator/Q/P/R/I`) now route through
+  `Error::Display(Error(msg, token, *i))` so they participate in
+  exit-code propagation, mirroring the `5c0227b` CLIP fix.  Guarded
+  by `RegisterAllocator: uninit-read produces a non-zero exit` in
+  `test_parser_families.cpp`.
+
+---
+
+## 4. Runtime validation via ps2gl samples
+
+The ps2gl example apps are the **functional** regression suite. Each
+exercises a different slice of the library + VU1 renderers.
+
+### Sample matrix (built artifacts in `build-test/examples/`)
+
+| Sample            | Renderer(s)              | Renders with openvcl? | Renders with `PS2GL_USE_SCE_VSM=ON`? |
+| ----------------- | ------------------------ | --------------------- | ------------------------------------- |
+| `nehe_lesson02`   | `general*`               | ✅                    | ✅                                    |
+| `nehe_lesson03`   | `general_pv_diff*`       | ✅                    | ✅                                    |
+| `nehe_lesson04`   | `general*` + `_quad`     | 🟡 triangle yes, quad no | ✅                                  |
+| `nehe_lesson05`   | `general*` + `_quad`     | 🟡 triangle yes, quad no | ✅                                  |
+| `box`             | `general*`, `_quad`      | ❌ all-quad cube blank | ✅                                    |
+| `logo`            | `general*` + texturing   | (not yet tested)      | (not yet tested)                      |
+| `performance`     | `fast*`, `general_quad/tri` | (not yet tested)   | (not yet tested)                      |
+| `tricked_out`     | own VU1 + `general*`     | (not yet tested; built from pre-built `_vcl.vsm`) | n/a |
+
+### Defining "done"
+
+A sample passes when:
+1. ELF builds with the all-open pipeline (`openvcl + masp + dvp-as`).
+2. It boots in PCSX2 to the rendering loop (no early `SIF crash` / TLB miss).
+3. Screenshot matches the golden within tolerance (image-diff with
+   PSNR / SSIM threshold; bitwise compare fails on emulator jitter).
+4. (After §2.2 lands) Frame time within ~10 % of legacy-pipeline ELF.
+
+Steps (1)–(3) are functional parity; (4) is the perf milestone tied to the
+scheduler.
+
+### Suggested automation (not yet built)
+
+```
+for sample in build-test/examples/*.elf; do
+  mcp__pcsx2.reset_vm
+  mcp__pcsx2.boot_elf $sample
+  # wait N frames OR watch for known framebuffer signature
+  mcp__pcsx2.screenshot > validation/$(basename $sample)_openvcl.png
+  mcp__pcsx2.shutdown_vm
+done
+# image-diff each PNG vs validation/<name>_golden.png
+```
+
+---
+
+## 5. Fast iteration loop — `/ps2dev` + PCSX2
+
+The standing dev loop is the `/ps2dev` skill (build / SDK / toolchain) glued
+to `mcp__pcsx2.*` runtime tools. Use it whenever changes touch `vu1/`,
+`openvcl/src`, `masp/src`, or anything that links into `libps2gl.a`.
+
+| Step                | Tool                                                                                  |
+| ------------------- | ------------------------------------------------------------------------------------- |
+| Build               | `/ps2dev` skill                                                                       |
+| Boot ELF            | `mcp__pcsx2.boot_elf` (or `ps2link_execee` for hardware)                              |
+| Confirm rendering   | `mcp__pcsx2.screenshot` + image-diff against golden                                   |
+| Skip past boot      | `mcp__pcsx2.save_state` / `load_state` once a sample reaches its render loop          |
+| Inspect VU1 / GS    | `mcp__pcsx2.pause_vm` + `read_memory_range` (VU1 data at `0x1100C000`, 16 KB)         |
+| Reset between runs  | `mcp__pcsx2.reset_vm` / `shutdown_vm`                                                 |
+
+Useful PCSX2 address landmarks for ps2gl debugging:
+- VU1 data RAM at `0x1100C000` (16 KB; first ~1.5 KB is constants/matrices,
+  rest is output buffer + scratch).
+- Sony's working quad outputs vertex positions at `0x1100D390`+ — useful
+  reference for the quad-bug diff.

+## 6. Quick reference — commands
+
+```bash
+# Build openvcl + install to toolchain
+cd ~/Projects/openvcl
+make openvcl
+cp openvcl ~/toolchains/ps2/ps2dev/bin/openvcl
+
+# Run openvcl on a single shader (smoke test)
+./openvcl --gasp masp general.vcl > /tmp/out.vsm

+./openvcl test/repro/quad_adc_bug.vcl -o /tmp/quad_repro.vsm
+diff -u test/repro/quad_adc_bug.vsm.openvcl-output /tmp/quad_repro.vsm
+```
+
+---
+
+## 7. Open questions to resolve
+
+1. **Legacy `Makefile` in `ps2gl/`**: do any downstream consumers (PS2DEV
+   ports, package recipes) still depend on it? If not, delete.
+2. **vsm-diff target**: as openvcl converges with Sony, do we accept
+   "semantically equivalent but allocator chose different regs", or chase
+   byte-equivalent VSM?
+3. **Golden screenshots for runtime validation**: do we have any from a
+   legacy-pipeline build (CI artifacts, checked-in PNGs, etc.) we can use
+   as the ground truth? If not, the first open-pipeline run becomes the
+   de-facto golden after manual visual verification.
+4. **Quad-bug priority vs scheduler**: fix the quad bug first
+   (correctness — open pipeline works for all 13 renderers), or land the
+   scheduler first (performance — open pipeline approaches Sony's perf)?
+   The workaround (`PS2GL_USE_SCE_VSM=ON`) means we don't *have* to
+   choose immediately, but at some point one path needs picking.

-###
-### 	To specify a particular build include the name of the build anywhere on
-### 	the command line:
-### 		make xrun optimized,
-###   	make clean optimized, etc.
-###
-### 	Included builds (add your own!):
-### 		debug
-###		optimized	(default)

+Compare two VU1 .vsm files at the semantic level.
+
+Used as a CTest target in ps2gl to verify that openvcl produces the same
+*set* of operations as Sony's proprietary vcl for each VU1 renderer.
+Differences in pipe-pairing, register-allocator choices, and whitespace
+are intentionally ignored -- the goal is to surface real divergences
+(missing instructions, wrong opcodes, missing labels) and to track how
+close openvcl is getting to the reference as the dual-pipe scheduler
+matures.
+
+Usage:
+  vsm_diff.py <reference.vsm> <openvcl.vsm>
+
+Exit codes:
+  0 = histograms and labels match.
+  1 = real divergence (different opcode set, different label set).
+  2 = file read / parse error.
+
+The script is intentionally permissive about pipe placement: only the
+opcode mix matters.  A separate "instruction-count delta" line is printed
+to track scheduler progress over time.

-### Copyright (c) 1999, 2000, 2001, 2002 Sony Computer Entertainment America Inc.
-###	All rights reserved.
-### 
-### Boilerplate Makefile by Bret Mogilefsky (mogul@playstation.sony.com)
-### 	and Tyler Daniel (tyler_daniel@playstation.sony.com)
-###
-###	Use this makefile as a template for new projects!
-### 
-### General Features:
-###
-###	Just specify SRCS and go!
-###	Automatic and minimal (fast!) dependency generation (for vu microcode as well)
-###	Allows keeping source and headers from src and include dirs, or elsewhere.
-###	Builds in a subdirectory.
-###	Allows additional defines, include dirs, and lib dirs without 
-###		specifying -D, -I, and -L
-###	Easy to specify parallel builds (debug, optimized, release, etc)
-###	Easy to add flags on a per-file, per-build, or per-file-build basis
-###	Can specify parent projects to make first (libraries)
-###	Builds libraries
-###	Slices, dices, feeds your cat, calls your mum.
-###
-### VU microcode features:
-###
-###	Generates depencies for microcode (for .include and #include)
-###	Uses a preprocessing script to manage registers (configurable)
-###	Runs the c preprocessor over microcode - you can use #define and #include
-###		freely (and share #defines with c/c++)
-###	Support for vcl
-###
-### Useful targets:
-###
-###	run		Run the executable.
-###	xrun		Run the executable under a new xterminal.
-###	clean		Remove everything we can rebuild.
-###	tags		Generate source-browsing tags for Emacs.
-###
-### Using builds:
-###
-### 	To specify a particular build include the name of the build anywhere on
-### 	the command line:
-### 		make xrun optimized,
-###   	make clean optimized, etc.
-###
-### 	Included builds (add your own!):
-### 		debug
-###		optimized	(default)
-###		release
-###
-###	For more info see the "Build Options" section below

-###	All rights reserved.
-###
-### Boilerplate Makefile by Bret Mogilefsky (mogul@playstation.sony.com)
-### 	and Tyler Daniel (tyler_daniel@playstation.sony.com)
-###
-###	Use this makefile as a template for new projects!
-###
-### General Features:
-###
-###	Just specify SRCS and go!
-###	Automatic and minimal (fast!) dependency generation (for vu microcode as well)
-###	Allows keeping source and headers from src and include dirs, or elsewhere.
-###	Builds in a subdirectory.
-###	Allows additional defines, include dirs, and lib dirs without
-###		specifying -D, -I, and -L
-###   Easy to specify parallel builds (debug, optimized, release, etc)
-###   Easy to add flags on a per-file, per-build, or per-file-build basis
-###	Can specify parent projects to make first (libraries)
-###	Builds libraries
-###	Slices, dices, feeds your cat, calls your mum.
-###
-### VU microcode features:
-###
-###	Generates depencies for microcode (for .include and #include)
-###	Uses a preprocessing script to manage registers (configurable)
-###	Runs the c preprocessor over microcode - you can use #define and #include
-###		freely (and share #defines with c/c++)
-###	Support for vcl
-###
-### Useful targets:
-###
-###	run		Run the executable.
-###	xrun		Run the executable under a new xterminal.
-###	clean		Remove everything we can rebuild.
-###	tags		Generate source-browsing tags for Emacs.
-###
-### Using builds:
-###
-### 	To specify a particular build include the name of the build anywhere on
-### 	the command line:
-### 		make xrun optimized,
-###   	make clean optimized, etc.
-###
-### 	Included builds (add your own!):
-### 		debug
-###		optimized	(default)
-###		release
-###
-###	For more info see the "Build Options" section below
