按 docs/ 目录逐篇核对，只改与事实/路径不符的部分，不动尚未验证的计划条目： - `docs/steps/**` 在早前整理时已迁到 `docs/reference/steps/**`，全仓的旧路径 引用（PLAN.md / README.md / M0-gr2-reader.md 及 libgr2 的头注释）一并改正。 - CLIENT-GAP.md / CLIENT-GAP-FIX.md / BACKLOG.md / MIDREVIEW.md：把已经落地的 条目从「待办」改为已完成，删掉与代码现状矛盾的描述。 - ANDROID-TESTING.md / CLIENT-PORT.md / CLIENT-ROADMAP.md / GODOT-POC-PLAN.md / SHINSOO-WORLD-RENDERING.md / PARITY-GAP.md：同上，另补当前实际的构建/测试入口。 - THIRD-PARTY.md：补齐实际在用的第三方来源与许可说明。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SJugvEJwz3FK4hw9ti3SRb

reference/ — archived from xrender-poc
These docs come from xrender-poc, the bgfx-based rendering POC that was
retired on 2026-08-29 in favour of the Godot route (this repo). See
../MIDREVIEW.md for the decision.
They are kept because the reverse-engineering knowledge is route-independent and still authoritative:
| file | what's still useful |
|---|---|
steps/M0-gr2-reader.md |
the entire .gr2 v6/v7 format breakdown that libgr2 implements — header, sections, Oodle1, self-describing type tree, granny_transform, OldCurveType B-splines, the "明确不做" table. libgr2 is vendored here now (../../libgr2). |
steps/00-oracle.md |
how the Wine + MinGW Granny oracle works — the ground truth for libgr2 numeric verification. Oracle harness vendored at ../../oracle/. |
steps/M1-static-render.md |
material-binding chain (granny_material → .Maps[].Map → granny_texture.FromFileName), DDS/DXT decode, the bgfx-era gotchas. The material logic maps 1:1 onto m2_material.cpp here. |
steps/M2-anim-skinning.md |
CPU LBS formula, sample_pose retarget-by-bone-name, the Granny normal-transform (plain 3×3, no inverse-transpose) — same math the GDExtension uses. Numeric gates vs Granny (≤6.5e-5). |
steps/M3-mobile.md |
iOS/Android notes from the bgfx shells — historical; Godot handles platform now. |
steps/M4-realistic-load.md |
eterpack / full-load plan — deferred in both routes. |
PLAN.md |
the bgfx-route master plan. §01 (go/no-go criteria, "工程性延期 vs 方案性死路"), §05 (format findings), §07 (visual-diff layering) are still the shared vocabulary. |
DEMO-PLAN.md |
bgfx RHI demo design record. Mostly superseded; kept for the shader/material-stage analysis. |
Relative paths inside these files (../libgr2, oracle/, test/golden/…,
engine/…, app/…) refer to the old xrender-poc layout. The mapping:
| old (xrender-poc) | now (metin2-client; the repo was created as mtgodot-poc and renamed later — the mtgodot-poc.app / .apk artifact names and the org.internal.mtgodotpoc bundle id did not change) |
