# SotS RE campaign — coverage dashboard Generated 2026-09-08 16:15 UTC · `sots-re` @ f328b82,2026-09-08 · `sots-engine` @ b2bad30,2026-09-08 (136 commits) · regenerate with `tools/dashboard.py` > **North star:** A functional reimplementation of the engine — behavior-equivalent, NOT byte-for-byte ## 1. Map coverage (campaign/board.md) 207 targets · mapped-or-better **177/207** `[█████████░] 86%` · verified **146/207** `[███████░░░] 71%` | Status | Count | % | |---|---:|---:| | verified | 146 | 71% | | mapped | 31 | 15% | | in-progress | 2 | 1% | | backlog | 26 | 13% | | blocked | 2 | 1% | | Type | verified | mapped | in-progress | backlog | blocked | total | |---|---:|---:|---:|---:|---:|---:| | objects | 26 | 6 | 0 | 2 | 1 | 35 | | control-flow | 11 | 2 | 0 | 1 | 0 | 14 | | subsystems | 3 | 7 | 1 | 3 | 1 | 15 | | engine | 20 | 0 | 0 | 0 | 0 | 20 | | verify | 37 | 7 | 0 | 16 | 0 | 60 | | phase2 | 10 | 3 | 1 | 2 | 0 | 16 | | meta | 34 | 6 | 0 | 1 | 0 | 41 | | other | 5 | 0 | 0 | 1 | 0 | 6 | ## 2. Binary understanding - RTTI type descriptors: **1,924** (`Game::` 1,404, `Mars::` 194; serializable types 179) - Classes with recovered member layouts: **384** / 1,598 named classes `[██░░░░░░░░] 24%` — `objects/layouts.json` (serializer recovery) plus classes recovered by hand in `struct-recovery.md` + `schema-gaps-resolved.md`. Note 179 types are *serializable*; the recovery also reaches non-serializable ones, so this is not a subset of that - Functions: **41,411** (parsed from `01-fingerprint.md`); named/annotated in the **address contract** (`ghidra/addresses.json`, not Ghidra's full rename count): **875**, verified **838** `[██████████] 96%` ## 3. Data layer - Catalogs: **1,595/1,595** files parsed (91 block kinds in `schema_stats.json`), dangling cross-refs **0** (`crosslink.json`) - Oracle `mars-parse`: **1,531/1,531** files agree `[██████████] 100%` - Oracle `mars-text`: **64/64** files agree `[██████████] 100%` - Saves: **11/11** real saves strict-clean — strict exit 0, 0 errors, 0 warnings - Design rules: **127/127** stock designs pass `[██████████] 100%` ## 4.
