docs(workflow): align CLAUDE.md + memory + roadmap with named-retail foundation

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).

+### Phase R — Retail research infrastructure
+
+**Goal:** sustainable, scalable access to retail-client decompilation —
+named symbols, struct layouts, wire schemas — so every future port is
+a 5-second grep instead of 30-minute archaeology.
+
+**Sub-pieces:**
+
+- **✓ SHIPPED — R.1 — Named-retail corpus committed.** Shipped 2026-04-25
+  (commit `a9a01d8`). `docs/research/named-retail/{acclient_2013_pseudo_c.txt,
+  acclient.h, acclient.c}` + `docs/research/data/spells.csv` + vendored
+  `references/actestclient/`. 1.4 M lines of named pseudo-C (99.6% function
+  naming) + 70K lines of verbatim retail headers + 3,956 spells with `Family`
+  for buff stacking + machine-readable wire schema in `messages.xml`.
+- **✓ SHIPPED — R.2 — pdb-extract tool + JSON sidecars.** Shipped 2026-04-25
+  (commit `69d884a`). `tools/pdb-extract/pdb_extract.py` reads
+  `refs/acclient.pdb` (Sept 2013 EoR build) and emits `symbols.json`
+  (18,366 named functions) + `types.json` (5,371 named struct types) to
+  `docs/research/named-retail/`. Pure Python, no deps, runs in <1 s.
+- **✓ SHIPPED — R.3 — actestclient vendored.** Shipped 2026-04-25 alongside
+  R.1. `references/actestclient/` (covered by `references/` gitignore)
+  includes the canonical `messages.xml` AC-protocol wire schema.
+
+**Acceptance:** Step 0 of `CLAUDE.md`'s development workflow points at
+`named-retail/` first; subsequent issue closures (#6 / #7 / #9 / #11)
+all consume this foundation.
+
+**Effects on other phases:** Issue closures unblocked by Phase R land
+under their existing letter phases (#6 enchantment buffs → Phase D /
+F.5 maintenance; #7 PlayerDescription trailer → Phase H.1 / F.2
+maintenance). The PDB symbols + headers also accelerate any future
+port in any phase — no separate listing here.

 ## Cross-cutting work tracked in parallel
 
 - **Test coverage.** Each phase lands with unit + integration tests in `tests/`. Current count: 98 Core + 96 Core.Net = 194. Keep the ratio as new phases land.
