alex 5b7e693bd0 Z: defer to lane I's audited inventory -- seven entry points, eleven inlined-draw functions 
The primitive count went three -> four (this lane) -> seven (lane I) while this
measurement was being taken, and not one number in the ledger moved. That is
the argument for reading state instead of counting calls, stated where it is
now demonstrable rather than merely asserted.

README.md

sots-re

Reverse-engineering worklog for Sword of the Stars (2006, SOTS1) — the 32-bit DX9 original + expansions. The nitty-gritty: static/dynamic analysis notes, Ghidra & ReVa scripts, function/struct maps, D3D9 call traces, decomp progress, findings.

Where this runs

Analysis lab on spicy (PVE, 192.168.3.201):

  • CT111 sots-re — Linux workspace: Ghidra + headless ReVa server, radare2/rizin/cutter, binwalk. Hosts the Samba share and this repo's working tree at /srv/re-lab/notes.
  • VM140 sots-re-win10 — Win10 runtime + dynamic analysis (x64dbg, Cheat Engine, RenderDoc/apitrace, DXVK→CPU-Vulkan for GPU-less rendering).

Infra (guests, storage, network, share, ReVa endpoint) is documented from the system-maintainer POV in trikilli → services/re-lab.md. This repo is everything else.

Layout

  • findings/ — the running findings log (append-only), one file per subsystem.
  • ghidra/ — exported scripts, data-type archives, struct definitions.
  • traces/ — D3D9 / Win32 API call captures + analysis.
  • scripts/ — helper tooling (loaders, extractors, parsers).
  • notes/ — session notes, scratch, hypotheses.

Ownership / legality

Game binaries come from the owner's own GOG/Steam copy. RE is for personal interoperability, bug-fixing, and preservation. Binaries themselves are not committed here (see .gitignore) — they live on the lab's Samba share /srv/re-lab/samples.

Campaign (how this repo is run)

A 4-agent crew (defined in ~/.claude/agents/re-*.md) runs the exploration: re-quartermaster (backlog + board) → re-analyst (maps via ReVa) → re-verifier (proves vs real data; old-vs-new differential once reimpl starts) → re-scribe (files the note, links it, commits).

  • campaign/board.md — live status board (start here).
  • Live tracking = Forgejo issues on alex/sots-re (labels status/* are the kanban columns; type/*, conf/*). campaign/board.md is the editable mirror — publish with scripts/forgejo_campaign.py bootstrap (needs FORGEJO_TOKEN).
  • campaign/backlog.md — prioritized target queue.
  • campaign/open-questions.md — unresolved threads.
  • findings/_template.md — the record format every finding follows.
  • findings/{objects,control-flow,subsystems}/ — the growing engine map.
  • verify/{parsers,traces,harness,results}/ — validation: struct parsers now, golden-trace replay + shim compare-mode for reimplementation.
  • ghidra/ — exported scripts + datatype archives.

Approach & north star: findings/00-strategy.md. Binary facts: findings/01-fingerprint.md.

Sibling repo

alex/sots-engine — the from-scratch engine source (clean-room, public-capable). This repo keeps the evidence + planning for both; binary facts cross over only via ghidra/addresses.json → tools/gen_addresses.py.

  • guides/re-windows-2000s-howto.md — annotated bibliography + how-to for RE of mid-2000s MSVC/DX9 Windows games, with our-experience call-outs.
