+# Darts Artwork
+
+Generated with the built-in image-generation tool. Runtime assets live in
+`assets/animations/darts/`; original selected PNGs are in this directory.
+All grid cells are extracted at one common scale. No separately generated limb
+pieces or stretched forearms are used.
+
+## arm-throw-v3.png
+
+Sports game animation sprites, harmless pub darts. Create a 4x4 equal-grid
+transparent sprite atlas, 16 frames, square 1536x1536. FIRST PERSON from the
+thrower's eyes looking at their OWN RIGHT forearm and hand aiming a small
+regulation sports dart FORWARD INTO THE SCREEN toward a distant dartboard,
+NOT horizontally sideways across the picture. Strong perspective foreshortening:
+the blue tail flights are closest to viewer; steel point points AWAY FROM
+VIEWER, deeper into scene, above and slightly left of flights. Entire forearm
+and visible bent elbow, dark shirt rolled ABOVE elbow. Right upper arm extends
+toward lower right, elbow is near bottom right, forearm rises toward upper
+middle. Natural darts throwing posture seen from own eyes, not another person's
+side-on arm. Detailed realistic digitized retro game sprite art, natural skin,
+silver knurled barrel, blue nylon shaft and blue cross flights. Row1 four similar
+forward aiming poses. Row2 four gradual drawback poses bending elbow toward
+viewer. Row3 four gradual FORWARD THROW poses straightening elbow and opening
+fingertips; dart disappears after frame10, frame11 and12 are empty hand. Row4
+four empty-handed follow-through/recovery poses, whole forearm still visible.
+Same anatomy, elbow anchor, scale and lighting across frames. EACH WHOLE arm
+stays inside its exact grid cell, 10 percent clear transparent margin all sides,
+no overflow into neighboring cells. At most one coherent arm per cell. No scene,
+no board, no faces, no borders, no text, no artifacts, no wrist-only framing, no
+floating dart separated from fingers. Actual alpha transparent background.
+
+## dart-views-v1.png
+
+Asset sheet for a pub DARTS sports video game: ONLY a small realistic regulation
+steel-tip SPORTS DART, no people, hands or other objects. 4 by 4 equal square
+grid, 16 different coherent views on 1536x1536 transparent canvas. Same dart
+every cell: short sharp silver steel point, cylindrical metallic silver tungsten
+barrel with many machined knurled grooves and dark narrow grip rings, slim dark
+blue nylon shaft, translucent rich royal-blue four-cross tail flights with
+realistic curved edges and a small white stripe. Detailed realistic digitized
+game rendering, NOT low-poly, not paper triangles. The sporting dart is about
+14cm long and delicate, not a weapon. Rotate camera around the dart: row1 rear
+three-quarter views angle 0,6,12,18 degrees; row2 24,30,36,42 degrees; row3
+48,54,60,66 degrees; row4 72,78,84,90 degrees. Angle0: tail blue flights closest
+to camera, point recedes straight away and is mostly hidden. Angle90: complete
+clean SIDE VIEW, steel point to LEFT, blue tail to RIGHT. All intermediate angles
+smoothly reveal the left-pointing silver barrel. Horizontal projected axis, no
+vertical roll. Each entire dart centered in its own cell, same scale, 15 percent
+transparent margin all sides. Rear views are naturally narrow in width, side
+views longer, same physical scale. Studio highlights for clear metal detail,
+sharp blue tail. NO background, checkerboard, grid lines, captions, text or
+shadows outside the isolated dart. Actual alpha transparency.
+
+## lounge-wall-v1.png
+
+A production game environment texture: straight-on FLAT FRONT ELEVATION of the
+wide darts-lounge wall inside a richly furnished vintage casino. Square
+1024x1024 raster asset, realistic digitized 1990s adventure game art, crisp small
+details. NOT a room perspective photo, no sidewalls, no floor or ceiling. Wall
+occupies full image. Deep muted emerald painted plaster above waist-high dark
+walnut wainscoting, brass trim, cream plaster details, burgundy accents, varied
+restrained colors. Central wall area around x50%,y42% must be clean emerald
+plaster with space for a separate dartboard, no board drawn. Left around
+x26%,y42%: substantial black chalkboard in an aged brass frame with subtle
+hand-written darts scores and tally marks. Right around x76%,y42%: illuminated
+glass trophy cabinet with silver cups, darts memorabilia, folded burgundy cloth,
+a framed old tournament photo. Warm-shaded brass wall lamps around x33% and
+x67% at y23%, realistic pools of warm light on plaster, a small analog clock
+above centre. Lower quarter: wainscot, two low cabinets and a narrow shelf for
+chalk, coasters and a folded towel; leave centre lower wall clear. The composition
+should read as an established pub-sports corner of an elegant casino, not an
+elevator, not a small wooden box, not sci-fi, not orange all over. All objects in
+true front elevation, fixed to wall, coherent scale and consistent lighting.
+No people, hands, sports dart closeup, text labels, logos, watermark or frame
+outside the image.
+
+## board-v1.png
+
+Deterministically generated exact 20-sector sports geometry, not AI artwork.
+The sector order and scoring ring radii are shared with native scoring tests.

+
+## teller-actions-v1.png
+
+Reference: `../hall/fortune-room-v2.png`, top-row faceless hooded teller only.
+Transparent production sprite sheet, exactly eight columns by five rows, forty
+equal square cells. Front-facing seated upper body, navy embroidered robe,
+silver crescents, dark gloves, absolutely no face under the hood. Same silhouette,
+size, head and shoulder position in every cell. No table, chair, candles, scenery,
+labels or borders. Detailed painted retro pixel art. Row one: eight successive
+poses taking and splitting a deck and beginning overhand shuffle. Row two: eight
+successive packet-transfer shuffle poses ending with the deck centered. Row
+three: eight dealing poses, left hand holds the deck, right hand reaches forward,
+releases a card and retracts. Row four: eight card-turning and explanatory wrist
+and open-palm gestures. Row five: eight poses lifting and circling both hands
+around empty space for a separately rendered crystal ball. Articulate fingers,
+wrists, forearms and sleeves, no camera changes or torso bouncing. Render the
+whole sheet together for consistent character identity and palette.
+
+## seated-room-v1.png
+
+Full-screen 4:3 retro pixel-art background. First-person seated across an intimate
+round tarot table in a cramped cluttered midnight-blue occult cellar. Empty
+carved high-backed chair centered around 43 percent width, curtains behind it,
+no person. Dark blue velvet tabletop covers the lower 42 percent, silver edge
+trim and blank central area for separate cards. Teller will be composited with
+head at 43 percent width, 17 percent height and hands near 54 percent height.
+Left cabinets crowded with books, scrolls, herbs, skull and trinkets; right shelves
+with glass bottles, blue crystal and a hanging blue lantern. Deep shadow with
+cool candlelight, muted burgundy fabric and aged silver/brass accents. Believable
+untidiness, draped curtains above and at the sides. No table cards, deck, ball,
+lettering, numbers, UI or screen border. Keep the upper-right speech area clear.
+
+## tarot-symbols-v1.png
+
+Symbolic tarot atlas, exactly six columns by four rows, 24 equal portrait cells,
+no gaps, letters or labels. Objects rather than human figures; detailed retro
+pixel art, thin ivory borders, navy, silver, burgundy, gold and cyan. Row-major
+symbols: traveller's satchel/staff/cliff; wand/tools; pillars/moon; crown/wheat;
+stone throne; ceremonial hat/crossed keys; entwined roses/heart; chariot; lion/
+infinity; lantern/mountain; ornate wheel; scales/sword; inverted watch/tree;
+scythe/rose/hourglass; pouring cups; horned stone mask/chains; lightning/tower;
+star/water; moon/two towers; sun/sunflowers; trumpet/banner; globe/laurel. Last
+two cells: symmetrical silver crescent and stars on midnight-blue card backs.
+Keep each recognizable illustration completely within its consistent frame.
+
+## crystal-mist-v1.png
+
+Transparent VFX sprite sheet, exactly four columns by four rows, sixteen equal
+square cells. Identical crystal ball on a small antique silver stand, front view,
+fixed silhouette, scale and bottom-center anchor. No hands, person or table.
+Pale-blue smoke spirals clockwise through one full cycle across sixteen frames.
+Subtle blue sparks and lighting inside the glass, no text, faces, numbers or
+symbols. Keep stand stationary; vary the internal smoke, not object placement.
+Detailed painted retro pixel art, dark glass and luminous cyan-blue mist, clean
+transparent corners, no matte or background.

+# Darts
+
+The board is on the first-floor wall near the billiards area. It opens a native
+MASM darts match against Max. No Python, browser, external engine or network is
+required by the game.
+
+## Match
+
+- Both players start at 500. First to reach exactly zero wins.
+- Three darts per visit. Visits alternate between the player and Max.
+- Any scoring ring can finish. This is a custom 500-point straight-out format,
+  not tournament 501 double-out.
+- A negative remainder is a bust: the entire visit is cancelled and play passes
+  to the other player. A remainder of one is valid.
+- The casino bankroll and saved profile are not changed by this game.
+
+## Controls
+
+- Move the mouse to aim; the outlined cross marks the current hit point.
+- Hold the left mouse button to draw back, release to throw.
+- The hand and cross have the same smooth, mixed-phase sway. Holding the aim
+  longer than 1.2 seconds gradually increases fatigue, capped after 4 seconds.
+  Precise mouse motion is retained independently of the hall's 320px UI grid.
+  There is no extra
+  random scatter after releasing the button.
+- The target sector appears beside the turn indicator (S, D or T).
+- Tab opens/closes the live score sheet and pauses the current action.
+- R or the lower-right button starts a new match. Escape returns to the hall.
+
+## Visuals
+
+The throwing line is 2700 board millimetres from the target. The initial lens
+is adjusted so the board is only about 7 percent smaller on screen than the
+previous 2370mm/900px view. Its original 512px texture and scoring geometry are
+unchanged. Max watches the same moving aim point for a short release window;
+he does not reroll a hit or bypass the sway.
+
+The independent
+scene camera follows one immutable parabolic trajectory, passes beside the
+dart, returns behind it, pauses at the hit, then returns to the throwing line.
+The small fading trail samples the same trajectory.
+
+Whole-arm raster animation includes the elbow, draw-back, release and empty
+follow-through. A single rigid canvas transform aligns the held dart with the
+target; individual limb pieces are never stretched or assembled.
+
+The flying dart uses sixteen detailed camera-relative raster views. Its needle

+## Assets And Checks
+
+`tools/generators/pack_darts.py` is an offline asset packer. It builds the exact
+20-sector board and packs the generated arm, dart views and lounge artwork.
+Artwork provenance and prompts are in `assets/sprites/darts/prompts-v1.md`.
+
+`C:/Python314/python.exe tools/tests/check_darts.py` compiles the actual MASM
+scene into a native fixture and checks 67 scoring vectors, 20 complete bot
+matches, busts, per-player score isolation, immutable hits, real mouse-release
+events, fine high-resolution mouse input, sway/fatigue, board footprint, Tab
+behavior, camera motion and profile isolation. It renders native
+640x480 framebuffers, a contact sheet and a GIF under `build/darts/`.
+
+`--parity` compares tested procedure instruction/relocation signatures to the
+full shipping assembly object. The hall fixture additionally covers interaction
+dispatch and the unchanged stairs, doors, bar and fortune room.

 # Offline Fortune Teller
 
+## Currently Shelved (2026-10-22)
+
+The seated visual session no longer starts the worker or generates readings.
+The native scene deals and reveals cards, then explicitly says that explanation
+is not implemented. The crystal-ball scene is visual only, without academic
+grade selection or collection of student identity details. Existing inference
+sources and local model files are retained for future work, not required by the
+current game. The older AI archive is not an updated visual-session release.
+See `FORTUNE_SESSION.md` for the current runtime and verification.
+
+The following documents the previous experimental neural integration.

 The approved C++ exception is limited to the neural worker. MASM still owns the
 room, interaction, question input, card selection, dialogue rendering, process
 lifetime and all gameplay. No OpenAI API, Ollama, Python runtime, listening port,

+# Seated Fortune Session
+
+The room interaction opens a fixed first-person view across the table. No player
+position, camera or bankroll state is modified. Escape or Exit returns to walking.
+All runtime input, random card selection, state transitions and rendering are MASM
+in `src_graphics/fortune_dialog.inc`; Python only compiles offline image assets.
+
+## Tarot
+
+Enter a question (up to 240 CP1251 characters), then Ask or Enter. The question
+stays visible under the table for the entire reading and cannot change midway.
+Three distinct major arcana are selected in assembly, each with an orientation.
+The 22 symbolic illustrations have separately packed 180-degree reversed faces.
+
+Sequence: shuffle 3.2 s; deal cards individually 1 s each; turn a card over 0.8 s;
+show its name, orientation and honest unavailable explanation 3.6 s; repeat for
+the next two cards; show the overall-answer placeholder; finish. Continue can
+advance a completed speech, never skip a deal or a flip. Again clears the question
+only after completion; Selection can return to the choice of scenes at any time.
+
+Speech is composited beside the teller, not an OS window. Its border grows with
+the visible text. Characters reveal every 28 ms with a short upward pop. Rendering
+does not advance timers: the session updates from the game clock, with bounded
+steps after stalls. No neural worker or algorithmic reading generator is called.
+
+## Crystal Ball
+
+The second selection raises a crystal ball and animates gloved hands with swirling
+blue mist. It ends with an explicit unavailable-result line. There is no real
+student grading, inference of merit, identity form or automated academic decision.
+Again replays the visual sequence. This limitation is deliberate, not a hidden
+random grade presented as a judgement.
+
+## Assets
+
+Generated source art and production prompts: `assets/sprites/fortune/`.
+Offline packer: `tools/generators/pack_fortune_session.py`.
+Runtime packs: `assets/animations/fortune/` (ANM1 format).
+
+Forty authored poses are arranged on one shared anchored 8x5 sheet. Shared-canvas
+in-betweens yield 64 shuffle, 32 deal, 32 gesture and 32 orb-hand frames. Sixteen
+mist frames, 44 oriented card faces, a back and a 640x480 room complete the scene.
+Art loads only when seated and all seven packs are freed on exit/shutdown. The
+seated view is independent of the walking room's existing asset packs and map.
+
+## Verification
+
+Run `C:/Python314/python.exe tools/tests/check_hall_expansion.py` after packing.
+The fresh native x86 harness exercises real WM_CHAR input, length/backspace,
+empty/double submission, all stage transitions, card uniqueness, speech growth,
+question persistence, crystal-ball stages, exit during animation, asset cleanup
+and unchanged player position/bank. It writes actual framebuffer BMP/PNG captures
+and a 64-frame shuffle GIF under `build/hall-expansion/`. Python additionally checks
+native-frame differences, question pixels, pack integrity and reversed artwork.
+`--parity` checks these tested procedures against the shipping game object.
+
+The old multi-gigabyte neural ZIP is not rebuilt by this feature. Distributions
+must include the new `assets/animations/fortune/` directory with the updated game.

+# Native AI Observer
+
+The observer lounge opens a game selector rather than the old unavailable modal.
+All gameplay, decisions, rendering and input remain MASM32. No neural model or
+network connection is used.
+
+## Games
+
+- Heads-up Hold'em: the existing bot decision is shared by both seats.
+- Blackjack: an autonomous first seat plays against the normal dealer.
+- Durak: both throwing-in and transfer variants use the same legal-move bot.
+- Billiards: both pyramid and eight-ball seats use the existing shot planner.
+
+These are real rounds using the normal shuffled decks, settlement and billiard
+physics. The observer does not generate scripted winners. Both poker and Durak
+hands are visible to the spectator, but each bot still sees only its own cards
+and public information. Blackjack retains the dealer's normal hidden hole card.
+
+## Controls
+
+Select a game with the mouse, keys 1-6, or arrows and Enter. During a match:
+
+- Space or the pause button pauses/resumes decisions and animation.
+- Tab or the speed button cycles 1x, 2x and 4x.
+- N or restart starts a fresh round without adding an abandoned round to scores.
+- Escape or Games returns to the selector. Escape again returns to the hall.
+
+Completed rounds remain visible for three simulated seconds before another
+round starts. Each round uses a fresh virtual stack. Scores reset when choosing
+a different watching session. Human gameplay commands are discarded while watching.
+
+## Profile Isolation
+
+The observer snapshots the player's balance, RNG state, tournament flag, bets,
+game variants and blackjack/billiard opponent settings. These are restored before
+leaving. Native save, NPC-contract progress and loss-protection charms have an
+observer barrier. Watching does not spend personal funds, charms, grant balance
+achievements, progress contracts or write the profile.
+
+## Verification
+
+`C:/Python314/python.exe tools/tests/check_observer.py` compiles fresh native game
+and spectator procedures against existing rendering helpers. It runs 80 complete
+card rounds, checks both billiard seats, pause and profile restoration, compares
+runtime files before/after, and captures actual native framebuffers.
+
+After rebuilding the full game, `--parity` checks that the shipping procedures
+match the native-tested object. `test_billiards_module.ps1` additionally exercises
+ordinary human/AI billiards with observer mode disabled.
