Multi-region zones now default CurrentRegion to the entry region at
startExpedition; that region is also written to regions_visited so
the visited/cleared distinction is meaningful from Day 1.
MarkRegionVisited / MarkRegionBossDefeated expose the combat-link
hook surface. MarkRegionBossDefeated also flips Expedition.BossDefeated
when the cleared region's IsZoneBoss is set, since the zone-boss kill
is the same event from §7's POV (suppresses temporal accumulation,
kills further awareness pulses, etc.). setCurrentRegion is the
companion writer used by E4c's travel command.
!expedition status now shows the region line ("🗺 Region: Drow
Outpost (2/4)") with a ✓ marker when the region boss is down.
§8.3 siege economics:
- applyDailyBurn now takes an explicit siege flag and enforces a 2× floor
on supply burn even when HarshMod is below 2 (tier-1 zones still get
starved out per spec).
- currentBurn mirrors the same precedence so status/briefing readouts
stay consistent.
- Briefing rollover passes e.SiegeMode through, decoupling siege from
the harsh-conditions composite.
§8.3 threat-70 warning: applyDailyThreatDrift emits a one-time
appendApproachingSiegeLog when the level crosses 70 (prevLevel<70 and
new level≥70). Pulls from a new flavor.ThreatClockApproachingSiege pool
seeded with the spec's verbatim warning beat plus two voice-matched
alternates.
Other siege effects (boss +20 HP / Legendary Resistance, cleared-room
respawn, no-short-rest enforcement) stay deferred to the combat-link
phase — ThreatBandInfo already exposes the flags that engine will read.

Command surface for the multi-day expedition layer. Wired in
adventure.go alongside !zone. Subcommands: list (delegates to zone
list), start <zone> [Ns] [Md], status, log, abandon, help. Default
outfit is one standard pack; pack tokens parse as e.g. "2s 1d".
start debits coins via p.euro.Debit, refunds on persistence failure,
and blocks if a !zone single-session run is also active. Status
renders the §12.1 daily briefing block with HP, supplies (current
burn factors in harsh conditions / siege), threat threshold label,
and depletion warning if rationing or worse. log shows the last 5
ExpeditionEntry rows. abandon flips status to 'abandoned'.
Start uses the prewritten flavor.ExpeditionStart pool for the
narrative coda and writes it to the log so !expedition log shows it
back. Tests cover parser combinations (1s default, 3s 1d, error
paths), threshold band edges, the start→status→log→abandon roundtrip,
and the underfunded-start no-debit guarantee.
Day cycle (E1d) and !camp (E1e) wire on top in subsequent commits.
