§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.

Threshold model on top of the E1a persistence: ThreatBand bracketing
(Quiet/Stirring/Alert/Hostile/Siege) with per-band combat/supply/rest
knobs (ThreatBandInfo). Daily threat drift (+3/day, GMMood-modded:
effusive→-3 elated, hostile→+5 wrathful) wired into the 06:00 briefing
rollover; no-op once the boss is down.
Threshold crossings emit a flavor-bearing log entry pulling from the
prewritten flavor.ThreatClock{Stirring,Alert,Hostile,Siege} pools.
applyBossDefeatThreat is the -20 hook for the eventual combat-completion
wiring (combat→expedition link is a later phase).
Combat-driven modifiers (loud-ability, escape, combat-in-new-room) are
deferred to the same combat-link phase since expeditions don't currently
host their own combat path.
