Distilled from Chris Judnich's 'Decompiling a Nintendo 64 Game in 84 Days'
(saved under docs/reference/): explicit per-task budgets exposed to the
agent, a shared append-only learnings file, file-partitioned parallelism,
cheap pre-flight passes, and a standard investigation-subagent brief
template. PORT-LEARNINGS.md is a one-screen index of the recurring
N64->PC bug classes into PCPortResearch.md §F; AGENTS.md points to both.
- Move the two N64 reference screenshots out of the repo root into
docs/reference/ (n64-footage-2026-08-24.jpg, n64-footage-gun-barrel.png);
HANDOFF.md now points there.
- Gitignore screenshots/ (session captures) and tools_pc/mupen64/ (local
Mupen64 Plus checkout used for N64 reference footage; 8 MB of binaries).
- Commit tools_pc/mtxtest.c, the standalone fast3d matrix-convention
harness that HANDOFF/D72.3 docs reference as kept-for-reference.
- Refresh PORTING.md: status was still 'scaffolding / building once
implementation lands'; now reflects Phase 2 in progress and points at
docs/HANDOFF.md for current session state.
