Widens the written scope of AGENTS.md non-negotiable #2's ABI exception to
match established practice (runtime struct/union misreads, not just
ROM-serialized structs — the D209/D210/D255 pattern), states explicitly
that diagnosis into src/game is never restricted (only the fix is), and
defines a real three-bucket taxonomy + sign-off procedure (dev-process.md
§7) for the rare genuine-behavior-difference case, replacing the
undefined ad hoc "ask the user" gesture that's been referenced without
being defined across ~10 places in the docs.
Mirrors the same framing into CONTRIBUTING.md and the PR template for
external contributors. Extends porting-notes.md §A1 with D255 as a third
worked example and a tell-tale-signs checklist, explicitly distinguishing
it from D284 (same epistemic shape, different mechanism, no rule-2
question at all). Appends a ready-to-dispatch pass-10 brief to the D236
entry applying the new taxonomy to its actual next step.
Docs-only; no code/build changes. Per docs/dev/notes/RULE-2-CLARIFICATION-PLAN.md.
- README: attract-mode stills + demo GIF as the hero row, status/warning
callouts, metrics table, "Contents" index, doc-index table; simplified
the two-agent workflow diagram (LR -> TD, fewer edges) for GitHub web
- Table-of-contents indexes added to internals.md, porting-notes.md,
agentic-development.md, AUDIO-PLAN.md
- CI: add Windows/MSYS2 build job, minimal token (contents: read),
persist-credentials: false, concurrency group; run on main + master.
validate job regenerates the US ROM-asset symbol file only and configures
ntsc-final (PAL/JP need a region ROM; no ROM is used in CI)
- .github: SECURITY.md, issue forms + chooser config, PR template,
labels.yml, dependabot (Actions, monthly)
- Do not track the proprietary SGI IRIX IDO toolchain or SGIImageViewer.exe;
document in SetupGuide.md / building.md how to obtain IDO for N64 ROM
builds (the PC port does not need it)
- Stop tracking two committed *.pyc files; drop stale screenshots and a
redundant .gitignore line; misc doc cross-reference fixes
