- Adventure characters now record DeathSource ("adventure"|"arena") and
DeathLocation when killed. Threaded through Kill() and transitionDeath.
Daily report uses the recorded death location instead of misattributing
arena deaths to the day's adventure log: when DeathSource != "adventure",
the adventure block shows the alive icon and a separate "Later fell in
{location}." line. Standout-loss flavor uses DeathLocation. Empty
DeathSource (legacy rows) falls back to current behavior.
- calcDamage applies a ±15% per-hit jitter, so successive hits in a phase
no longer produce identical numbers. Previously every hit in a phase was
flat (e.g. 17, 17, 17, 17) and mirror-symmetric between player/enemy,
reading as scripted.
- assessThreat rewritten to use the engine's actual penetration formula:
damage-per-round each direction, then rounds-to-kill ratio. The old
additive HP+Attack*3 model ignored Defense, so even fights could be
rated trivial — players died after consumables were skipped with the
"threat assessed as manageable" message.
- SelectConsumables never skips on trivial when arenaRound > 0. Arena
losses cost real money and equipment, so the cost of a wrong assessment
is too high to gamble on; adventure-side fights still skip trivial
threats to avoid wasting items on chump enemies.
