Adds login/registration prompts on connection, database initialization on
startup, and periodic auto-save every 5 minutes in the game loop. Player
state is now tied to authenticated accounts.
Implements account management with password hashing (pbkdf2_hmac with SHA256)
and constant-time comparison. Includes player state serialization for position
and inventory persistence across sessions.
Captures the combat-as-content architecture: moves are TOML files,
engine is a state machine (IDLE→TELEGRAPH→WINDOW→RESOLVE). Documents
move set, counter relationships, damage formulas, and how combat
initiation works without a dedicated fight command.
Scan content/commands/ for .toml files at startup and register them
as commands alongside Python-defined ones. Two flavors: handler-based
(points to a Python callable via module:function) and message-based
(auto-generates a handler from inline text). Includes example MOTD
command, type validation, error logging, and full test coverage.
Each cloud in the trail gets a slightly longer TTL than the one
before it (0.15s stagger). The origin cloud dissolves first, then
each subsequent tile follows. Two consecutive flights produce a
trail where the oldest clouds are already gone.
fly with no args toggles flying on/off. Movement commands (fly east,
etc) only work while airborne. "You aren't flying." if you try to
move without toggling on first. Player.flying field tracks the state.
fly <direction> moves the player 5 tiles, ignoring terrain. Leaves
a trail of bright white ~ clouds that fade after 2 seconds. Effects
system supports arbitrary timed visual overlays on the viewport.
TinTin aliases: fn/fs/fe/fw/fne/fnw/fse/fsw.
Tileable Perlin noise: each octave wraps its integer grid coordinates
with modulo at the octave's frequency, so gradients at opposite edges
match and the noise field is continuous across the boundary.
Coarse elevation grid interpolation wraps instead of padding boundary
cells. Rivers can flow across world edges. All coordinate access
(get_tile, is_passable, get_viewport) wraps via modulo. Movement,
spawn search, nearby-player detection, and viewport relative positions
all handle the toroidal topology.

Removes notes/ — DAYDREAMING.txt became DREAMBOOK.md, charset-vs-mtts
expanded into docs/lessons/ with the connect_maxwait fix documented.
1000x1000 tile world generated deterministically from a seed using
layered Perlin noise. Terrain derived from elevation: mountains,
forests, grasslands, sand, water, with rivers traced downhill from
peaks. ANSI-colored viewport centered on player.
Command system with registry/dispatch, 8-direction movement (n/s/e/w
+ diagonals), look/l, quit/q. Players see arrival/departure messages.
Set connect_maxwait=0.5 on telnetlib3 to avoid the 4s CHARSET
negotiation timeout — MUD clients reject CHARSET immediately via MTTS.
