The turn engine seats a party since P3, but only seat 0 survived a
suspend: seats 1+ reopened from their Mods on every step, rearming their
once-per-fight one-shots -- a party Halfling rerolled a nat 1 every round.
Split CombatStatuses into the fight-scoped half (the enemy's stance, the
round cursor) and the per-character half, ActorStatuses. The embed is
anonymous and untagged, so statuses_json stays the same flat object it
always was and every in-flight prod row decodes unchanged.
Seat 0 keeps living on combat_session. Seats 1+ get combat_participant
rows. That asymmetry is the point: a solo fight -- which is every fight
that has ever run, and the whole balance corpus -- writes exactly the
bytes it wrote before, and no participant rows at all. roster_size
guards the read, so the solo loader never issues the second query.
Parties commit their seats in the same transaction as the session row;
solo keeps its single unwrapped UPDATE.
expedition_party is the co-op roster. No party_id on dnd_expedition:
expedition_id already identifies the party, and a second key would be a
second answer to "who is in this party". Absent means solo, in both new
tables, so neither needs a bootstrap backfill.
The combat characterization golden is byte-identical.
Also seeds and re-powers the two statistical subclass tests. They drew
from the package-global RNG, so their verdict depended on how much
randomness every test declared before them happened to consume -- which
is why they flaked on a clean tree. Sweeping 40 seeds: Precision Attack
had a mean margin of +127 wins against a +50 threshold but a worst case
of -42, and Assassinate averaged +12.8 with two seeds outright negative.
Both effects are real; the trial counts were too low to see them. Seeded,
and raised to 24000/6000 trials, where all 40 seeds clear.
The turn engine ran a fixed player -> enemy -> round_end phase machine over
one player and one monster. It now runs a round as a sequence of seats.
turnOrder derives that sequence per round. A solo roster short-circuits to
the historical [player, enemy] and rolls nothing -- the duel has never had
initiative, and handing the monster a coin flip on who swings first would be
a live balance change. A party rolls it with the auto-resolve engine's own
formula (speed + d10 + InitiativeBias).
Every seat in a round shares a (round, phase) pair, so the acting seat is
mixed into the RNG *seed* rather than the stream. Seat 0 and the enemy
sentinel mix to nothing, which is what keeps a solo fight drawing exactly
the pre-roster stream across a suspend/resume.
The round cursor persists as Statuses.TurnIdx, omitempty so no solo row
carries it. A fight that was in flight when the field landed decodes it as
0; turnIdxForPhase reconciles that against Phase, which is the older and
load-bearing field. Without it, a suspended enemy_turn would resume, step,
and land back on enemy_turn forever.
The enemy now picks a target uniformly among the standing roster (solo draws
nothing), a downed seat forfeits its turn silently, and the fight is lost
only when anyAlive() goes false -- not when the acting seat drops. That last
one fixes a latent solo bug on the way past: resolvePlayerSwings returns
false when a retaliate aura kills the swinger between extra attacks, and the
old code walked that corpse into the enemy's turn.
commit() reads seat 0 explicitly instead of the cursor, which the enemy turn
parks on its target and round_end walks across the roster.
TestCombatCharacterization is byte-identical: solo balance did not move.
Diagnosed a cleric "death loop" (L14 dying at T2/T3 bosses while
over-levelled): the boss isn't overtuned — caster sustained DPS is
under-delivered, compounded by a fragile healer build.
Engine fix — concentration AOE re-tick:
- Concentration damage spells (spirit_guardians, heat_metal, spike_growth,
call_lightning, flaming_sphere) now tick the enemy every round at
round_end instead of resolving as a one-shot, via a new
CombatStatuses.ConcentrationDmg armed on cast and round-tripped through
the turn engine. Closes the long-tracked turn-engine concentration gap;
the burst still lands the casting round, then the aura lingers.
- Sim picker skips re-casting an already-active aura (models competent play
and prevents a burst+aura double-dip). Re-baseline (n=30 sweep + n=100
confirm): bard +47pp T3 (heat_metal), druid +3-7, cleric/mage flat,
fighter unchanged — no regressions.
Player-data bootstraps (idempotent, run once on Init):
- bootstrapCasterSpellBackfill: ensureSpellsForCharacter only seeds an empty
book, so defaults added after a character's roll never reach it. Backfill
missing defaults into known+prepared for existing casters (gives the
affected cleric inflict_wounds + a working healing_word, since her
healing_word_spell is a dead alias).
- bootstrapGrantStarterPet: one-off L10 pet for an endgame player who never
got the morning arrival roll; adds per-round proc damage + deflect.
- TestScenario_JosieCasterAid verifies both against a copy of the live DB,
incl. idempotency.
Also fix a pre-existing wall-clock flake in
TestFireBriefings_EventAnchoredActivePlayerDelivers (start_date defaulted to
real now, filtering the row out when the suite runs after 06:00 UTC).
The live turn engine only struck once per fight and never rolled pet
deflect or whiff, so pet armor (deflect-only) bought nothing in real
runs. Roll pet attack each player turn and roll deflect/whiff per enemy
turn, mirroring the auto-resolve engine; retire the one-shot pet-proc
machinery (rollCombatSessionPetProc / PetProcReady).
(cherry picked from commit a0e41c97801e500efad13c7e9a06be4c345e464e)
Pet attacks were never resolved in turn-based fights. Roll the proc once
at fight start (a per-round roll would make a proc near-certain over a
long manual fight), persist it on the session so suspend/resume and
reaper auto-play honor the same outcome, and land a single pet hit on
the player's first acting turn.

A turn-based elite/boss combat session locks the run for up to 1h and
can straddle any scheduled tick. Add hasActiveCombatSession() and consult
it from the morning DM, midnight idle reaper, expedition briefing/recap,
and mid-day random event paths so none of them fire DMs or mutate run
state into a live fight.

CombatStatuses now mirrors every persistent combatState one-shot —
depleting resources (ward/spore/reflect/autocrit/arcane-ward/heal-
charges), once-per-fight class/race/subclass flags, and accumulated
buff stat deltas. resumeTurnEngine restores them; commit writes them
back in place. Fixes turn-based bugs where Orc rage, Halfling Lucky
reroll, and the Assassin first-attack bonus re-fired every round and
Abjuration Arcane Ward did nothing.
Buff spells and buff-type consumables (ward/atk/def/crit/spore/reflect/
auto-crit) are now usable mid-fight: a flattened-delta model diffs the
reused applySpellBuff/ApplyConsumableMods math against a throwaway
combatant, folds the marginal effect into the session, and re-applies
the persistent stat deltas onto the rebuilt player each round. Pure-
utility spells diff to nothing and are refused before a slot is spent.

A combat session abandoned past its 1h TTL is now resumed from persisted
mid-state and auto-played through the shared resolver to a real win or
loss, rather than flatly marked as a retreat. The bulk-UPDATE sweep is
replaced by listExpiredCombatSessions plus a reaper that locks the user,
auto-plays the fight, runs the normal close-out, and DMs the outcome.
markCombatSessionExpired remains the terminal fallback for sessions that
can't be reconstructed. Wired into eventTicker.

combat_session.go: CombatSession persistence layer mirroring the
dnd_expedition pattern — CRUD accessors, one-active-per-user enforcement,
and the timeout reaper (sweeps stale sessions to 'expired').
combat_turn_engine.go: the player_turn -> enemy_turn -> round_end -> over
state machine. advanceCombatSession seeds a deterministic per-(round,phase)
RNG, resolves one phase via the shared attack primitives, commits, and
persists. The deferred poison/status tick lands in round_end now that the
round-loop shape exists.
CombatStatuses persists only between-round monster-ability effects; the
reaper marks sessions 'expired' rather than auto-playing them — both gaps
depend on Combatant reconstruction, which lands with the command-wiring PR.
