alex df9431be64 AR: the raid target pick FIRES - TradeManager+0x0c is the per-system containing-sector table 
Decides lane AG's section 3.3 final paragraph, which lane AD correctly reported
it could not separate on sector 832.

STATIC: FUN_00841700 is the writer AG's section 7 lists as not found. It resizes
the +0x0c vector to the length of the systems vector -- the container trfr indexes
-- and fills it with containingSector[system.Idx] = sector. It runs from the
deserialiser, so a loaded save has it populated. G_B1a cannot reject a valid trfr.

LIVE: four raiders parked (2 CR on sector 832, 2 DE on sector 816), probes=8.
Slot13RngCalleeA entered 4x/turn at 4 words every turn; on turn 42 the pick fired
at 0x0088b613, calls=1 words=1, and the tail cost 5 words against 4 elsewhere.
The same run carries its own control: B entered on 832 twice at 0 words.

B costs ONE word, not two: FUN_00820af0's third short-circuit is a flag word
InitTable sets only for Human and Zuul, so AG's committed 3-words-on-success is 2.

Two hooks=off processes gave byte-identical autosaves, and so did a probes=8
process -- an oracle pair and a whole-save byte-neutrality proof for the
instrument, both firsts on this lineage.

Also first firings of 0x008939ee (rule 20's case study) and 0x00820c1b.

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.
