Update CLAUDE.md to current state, add session checkpoint

- CLAUDE.md: rewritten to reflect 112 rooms, corridor model, no prulez
  rooms, all keybindings documented, PDF as ground truth, screen reader
  patterns, cross-deck connection table
- Memory checkpoint for next session continuity

+**alien-rpg.el** (main engine, ~1370 lines, lexical-binding):
 
-- **Data**: `alien-rpg-rooms` (131 rooms as connection graph), `alien-rpg-decks` (10 decks A-J), `alien-rpg-character` (static), `alien-rpg-state` (mutable). Station name in `alien-rpg-station-name`.
+- **Data**: `alien-rpg-rooms` (112 rooms as connection graph), `alien-rpg-decks` (10 decks A-J), `alien-rpg-character` (mutable during session), `alien-rpg-state` (mutable, auto-saved). Station name in `alien-rpg-station-name`.
 - **Room IDs**: ASCII slugs (e.g., `B-ridici-stredisko`). Display names use Czech diacritics (`Řídící středisko`).
-- **Navigation**: Graph-based. `alien-rpg-move` (adjacent), `alien-rpg-teleport` (any). `alien-rpg-find-path` uses BFS to find ALL shortest paths.
-- **No dice rolling**: Player rolls physical dice. Engine tracks state only.
+- **Room data**: Each room has `:id`, `:deck`, `:name`, `:location`, `:note`, `:desc` (accessible description), `:connections`.
+- **Navigation**: Graph-based. `alien-rpg-move` (adjacent), `alien-rpg-teleport` (any). `alien-rpg-find-path` uses BFS to find ALL shortest paths. Path display uses bullet points with room names.
+- **Corridors as rooms**: Long corridors are modeled as rooms (e.g., `F-chodba` spans entire deck F from centrální šachta to cely). Side rooms connect to the corridor.
+- **No průlez rooms**: Průlezy (hatches between decks) are NOT separate rooms. They are direct connections between the rooms they physically sit in. Cross-deck connections noted in room `:desc`.
+- **Dice calculator**: `SPC G r` — yellow base dice (attribute + skill) + black stress dice. Player rolls physical dice.
 - **Weapons/Armor**: Structured plists — weapons: `(:name :bonus :damage :range :ammo :weight)`, armor: `(:name :rating :weight)`.
-- **State**: Health, stress, injuries, conditions, weapons, armor, gear, notes. Auto-saves via `alien-rpg--autosave`.
-- **Keybindings**: `SPC G` prefix (Doom Emacs). No `r` (roll removed). `a` = armor, `c` = condition.
+- **State**: Health, stress, resolve, story-points, injuries, conditions, weapons, armor, gear, tiny-items, notes. Auto-saves via `alien-rpg--autosave`. No buddy/rival/xp (not used in this campaign).
+- **Character**: prof. Héctor Navarre, biochemický inženýr, 74 let. Attributes and skills editable via `SPC G e`.
+- **Output**: All commands output to `*Alien RPG*` buffer via `switch-to-buffer` (not `pop-to-buffer` — avoids Doom popup behavior that confuses screen readers).

 ## Key Design Constraints
 
-- **Concise output**: 3-5 lines per command. No emoji, no decorative borders. Room codes everywhere.
-- **Screen reader friendly**: All interactions via minibuffer completion or short buffer output.
+- **Concise output**: Room descriptions 1-2 sentences. No emoji, no decorative borders. Room codes in brackets.
+- **Screen reader friendly**: All output via `switch-to-buffer` to `*Alien RPG*` buffer. Minibuffer completion for selection. No popups.
 - **Zero dependencies**: All data embedded in Elisp. No external files at runtime.
 - **Doom Emacs required**: `map!` macro, `SPC` leader.
-- **PDF-verified data**: Room names and connections verified against `reference_pdf/` maps. Thick red lines on maps = doors. Centrální šachta = round room with upside-down person icon.
+- **PDF-verified data**: Room names, connections, and character data verified against `reference_pdf/`. Thick red lines on maps = doors. Centrální šachta = round room with upside-down person icon.
+- **State changes use setq**: All `plist-put` on `alien-rpg-state` wrapped in `setq` for reliability.
 
 ## Map Structure
 
 - Decks A (top) to J (bottom), vertical station
 - Central shaft: B-J (A is isolated, access from B only)
-- Průlezy F↔G: F1↔G1, F2↔G2, F5↔G5, F6↔G6, F7↔G7, F8↔G8
-- Průlezy G↔H: G3↔H3, G4↔H4, G7↔H7, G8↔H8, G9↔H9 (communication tower)
+- F-chodba: main corridor spanning entire deck F, connects centrální šachta to cely. Zbrojnice, kuchyně, sklady, WC are side rooms.
+- Cross-deck průlezy modeled as direct room-to-room connections (no průlez rooms):
+  - F-chodba ↔ G-hangar-01 (F5/G5), G-hangar-02 (F6/G6), G-nakladovy-dok (F1/G1), G-opravarensky-dok (F2/G2)
+  - F-cely-z ↔ G-nakladovy-dok (F7/G7), F-cely-v ↔ G-opravarensky-dok (F8/G8)
+  - G-nastupni-hala ↔ H-nadrz-toxickych (G3/H3, G4/H4)
+  - G-nakladovy-dok ↔ H-plasma-jz (G7/H7), G-opravarensky-dok ↔ H-plasma-jv (G8/H8)
+  - G-shromazdiste ↔ GH-komunikacni-vez (G9), H-ridici-centrum ↔ GH-komunikacni-vez (H9)
 - G9 connects via Nouzové shromaždiště (top of G), NOT centrální šachta
-- F centrální šachta is at TOP of deck F, connects to Zbrojnice via corridor
+- GH-komunikacni-vez connects to H-ridici-centrum (NOT H-centrální šachta)
 
 ## Development
 
-No build system, tests, or CI. Load via `(load! "~/alienrpg/alien-rpg")` in `~/.doom.d/config.el`. Internal helpers use `alien-rpg--` double-dash prefix.
