CLAUDE.md edits (6 surgical ranges):
- Goal section: introduce named-retail/ as primary; old chunks
remain as fallback for chunk-by-chunk address-range navigation.
- Workflow renamed to "grep named -> decompile -> verify -> port"
with a new STEP 0 GREP NAMED FIRST. Decompile demoted to a
fallback (Step 1) for the rare obfuscated/packed minority that
pseudo-C lacks.
- Function-map citation updated to point at symbols.json + the
cross-port hand-curated table.
- "Do not guess" rule strengthened: PDB has the answer for almost
everything; guessing is now negligence.
- Phase completion checklist accepts named symbols + addresses.
- Reference hierarchy table gets a new top row pointing at
docs/research/named-retail/ as the primary oracle for any
AC-specific algorithm — beats every other reference.
memory/project_named_decompilation.md (new): evergreen crib-sheet
with file inventory, grep examples, hard rules. Pattern matches
project_ui_architecture.md.
memory/project_retail_research_index.md: updated preamble to point
named-retail/ as first stop; older slices remain useful for
pseudocode + C# port sketches.
memory/project_collision_port.md: rewrote the "Decompiled ground
truth" section to put named-retail/ first, chunks second. The
"DECOMPILE FIRST" mandate becomes "GREP NAMED FIRST, then DECOMPILE
FALLBACK".
docs/architecture/acdream-architecture.md: Guiding Principle text
updated to introduce named-retail as the primary decomp source.
docs/plans/2026-04-11-roadmap.md: new Phase R block — Retail
research infrastructure. R.1 (corpus, shipped a9a01d8), R.2
(pdb-extract, shipped 69d884a), R.3 (actestclient vendored,
shipped a9a01d8). All marked SHIPPED 2026-04-25.
Auto-loaded MEMORY.md index updated with a new entry pointing at
project_named_decompilation.md so post-compaction sessions inherit
the workflow change automatically.
Acceptance verified:
- grep -c "named-retail" CLAUDE.md = 9 (>= 3 required)
- grep -c "named-retail" MEMORY.md = 1
- dotnet build green (docs-only commit, but verified)
Foundation phases A + B + C all landed. Next: Phase D files
ISSUES #8/#9/#11 + closes #10 (KillerNotification orphan parser).

Project: named-retail decompilation foundation
Agreed 2026-04-25. Read once per session. Foundation commits:
a9a01d8 (corpus), 69d884a (pdb-extract tool).
What changed
The retail-client decompilation has gone from "FUN_xxx Ghidra chunks +
71 hand-mapped functions" to "18,366 named retail functions + 5,371
named struct types + verbatim retail headers", all committed under
docs/research/named-retail/. The acclient.pdb (Sept 2013 EoR build,
MSVC 7.00) is the source of truth.
Files at docs/research/named-retail/
| File | What | When to use |
|---|---|---|
acclient_2013_pseudo_c.txt (62 MB / 1.44 M lines) |
Binary Ninja pseudo-C with 99.6% naming. Address-prefixed lines. | Primary symbol lookup. Grep by class::method. |
acclient.h (1.7 MB / 70K lines) |
IDA-decompiled retail headers. Every struct verbatim. | Struct field names + offsets. Grep by struct name. |
acclient.c (46 MB / 1.3 M lines) |
IDA full-binary export. Mixed FUN_/named, but has named struct fields. | Cross-reference when pseudo-C body is corrupt. |
symbols.json (3 MB) |
18,366 entries: address + name (demangled Class::Method) + mangled (raw MSVC ABI). |
Programmatic name↔address lookup via jq. |
types.json (506 KB) |
5,371 named class/struct records with size + kind. | Programmatic type-layout queries. |
Workflow change — STEP 0 GREP NAMED FIRST
CLAUDE.md workflow now starts with Step 0 before the older
DECOMPILE step:
# Find a function body
grep -n "CEnchantmentRegistry::EnchantAttribute" \
docs/research/named-retail/acclient_2013_pseudo_c.txt
# Find a struct
grep -n "^struct.*CEnchantmentRegistry" \
docs/research/named-retail/acclient.h
# Programmatic
cat docs/research/named-retail/symbols.json | \
jq '.[] | select(.name == "CEnchantmentRegistry::EnchantAttribute")'
The older docs/research/decompiled/ Ghidra chunks remain a fallback
for the obfuscated/packed minority that pseudo-C lacks. ~5 second
grep replaces ~30 minute archaeology for typical lookups.
Hard rules
- Grep
named-retail/first. Always. The "Do not guess" rule in CLAUDE.md is upgraded: with the PDB available, guessing is no longer recoverable error — it's negligence. - Match by name, not raw address. The PDB build has a ~0xC00
byte delta vs the binary that produced our older chunks. Address
lookups in
symbols.jsonare correct; the olderacclient_function_map.mdhad several mid-body addresses (issue #9 sweep corrected them). - Regenerate JSON sidecars when needed:
py tools\pdb-extract\pdb_extract.py refs\acclient.pdb refs/stays gitignored. It's per-developer download cache; the committed extracts atdocs/research/named-retail/are what subagents and post-compaction sessions inherit.
Counts (Sept 2013 EoR build)
- 18,366 named public function symbols (
S_PUB32, code flag set) - 5,371 unique named class/struct types (filtered for non-forward-declared)
- 1,053 .obj compilation units recorded in DBI
- Build root preserved in PDB:
d:\ac1_sep13\
Why this matters
Closes / unblocks issues #6 (enchantment buffs in vital max — uses
CEnchantmentRegistry::EnchantAttribute at 0x594570), #7
(PlayerDescription trailer — uses CPlayerSystem::Handle_PlayerDescription
at 0x5636A0), plus reduces the cost of every future port from "30
min archaeology" to "5 sec grep".
