Recovery + restructure after rm -rf destroyed duckstation/build/ earlier this session. Adopts the nesrecomp pattern (see F:/Projects/nesrecomp): pristine upstream as submodule, our changes as a patch file that gets auto-applied by a setup script. Submodule: - duckstation/ now pins stenzek/duckstation@ffb33c281 (release-20260328 era) - .gitmodules records the pin; .gitignore stops ignoring the submodule path but still ignores build/ and dep/prebuilt/ (the submodule's own .gitignore also handles these) Patch + setup: - tools/duckstation/psxrecomp_oracle.patch (1187 lines, 7 files) captures our TCP debug-server on port 4371 plus the unfinished pc_break family of commands (with the VirtualMemoryAddress compile fix) - tools/duckstation/setup.sh clones submodule, fetches + verifies + extracts prebuilt Windows deps, rewrites stale absolute paths baked into the prebuilt CMake metadata, applies the oracle patch. Idempotent. - tools/duckstation/build.sh configures CMake (VS 17 2022) + runs MSBuild, then provisions bin/ with portable marker, BIOS copy, and settings.ini post-fixes - tools/duckstation/README.md documents the layout, the regeneration flow, and the known headless-boot configuration issue TCP documentation (salvaged from v3): - TCP_COMMANDS.md: full command table with native (4370) / duckstation (4371) / both columns, reflecting actual v4 implementation including wtrace_* and pc_break/pc_hit_last families - tools/debug_client.py: unified CLI from v3 (ports 4370/4371 match v4) - DEBUG.md: merged v3's END-TO-END COMPLETION RULE, Stale Hypothesis Rule, TOOLING RULE, and TOOL LIFECYCLE RULE sections into v4's existing loop Phase 4 diagnostic artefacts from this session: - generated/relocation_proofs/vblank_registrar/ — corrected VBlank-stall diagnosis. Prior handoff claimed the shell VBlank handler was never installed; live TCP inspection of both runtime and DuckStation oracle proved handler IS installed at 0x800DFEE0. Real gap is one level up in the kernel IRQ chain at *(0xA000E014). - tools/duck_query*.py, duck_search.py, disasm_ram.py, scan_*.py — focused probes used to establish the above; reusable against either server CLAUDE.md §2 and new §15 document the submodule-based oracle setup and the "never edit submodule, regenerate patch instead" rule. Known issues (tracked in tools/duckstation/README.md): - Fresh settings.ini doesn't complete BIOS boot under -nogui; one-time launch with GUI is required to warm up the settings before headless mode works Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
