dnd_zone_cmd.go ships handleDnDZoneCmd with subdispatch over the D1b
state machine: list, enter <id|#|name>, status, map, advance, abandon.
Bare !zone (or !zone list) shows zones available at the player's level
with !zone enter hints; an active run is flagged inline so the player
can't lose track of it.
Enter resolves zone input by ID, 1-based list index, or display name
(case/whitespace-insensitive, "the " prefix tolerated), and rejects
unknown / tier-locked zones plus duplicate concurrent runs without
clobbering the active run. Status reports current room / cleared /
loot / GM mood with a band label (effusive/friendly/neutral/grumpy/
hostile per design doc §3.2). Map prints an ASCII layout with ✓ for
cleared rooms and ▶ for the current room. Advance is a deliberate D1c
stub that calls markRoomCleared and reports the next room — combat
resolution per room wires in D1e. Abandon delegates to abandonZoneRun
and is idempotent (no-active surfaces a friendly DM, not an error).
Wired into adventure.go OnMessage right after the existing D&D
commands. 10 new tests cover dispatch (no-char nudge, list with char,
enter by ID and by index, unknown-zone rejection, duplicate-run guard,
status/map with no run, advance moves the room cursor, abandon clears
active and is idempotent), resolveZoneInput across ID/display/index/
case forms, and gmMoodLabel band edges. Full repo test suite green
(modulo a pre-existing RNG flake in
TestSimulateCombat_FirstAttackBonusImprovesEarlyHits unrelated to this
change).
TwinBee narration + mood triggers land in D1d.
