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.
P0 — actual bugs:
- eldritch_blast: SRD-imported "Whatever" placeholder leaked to players;
overlay added in dnd_spells_data.go.
- Battle Master disarming_attack + parry: math.Max on multiplicative
DamageReduct was a no-op vs the 1.0 default. Switched to *= and added
regression tests covering the stacking case too.
- Extended TestSpellDescriptionsAreJargonFree to catch "Whatever",
trailing ellipses, mid-word truncation, and empty-size phrases. This
surfaced 4 more genuinely-broken SRD descriptions (find_familiar,
clairvoyance, glyph_of_warding, teleportation_circle); all now
overlayed in dnd_spells_data.go.
P1 — UX hygiene:
- Setup completion now nudges new casters toward !spells/!cast.
- Magic-item attunement vocab unified to "bond" everywhere user-facing;
renamed the Treasures sheet section to avoid clashing with the bond
vocab.
- Ambient DM footers stripped of "Threat +N" / "Supplies −N SU" hidden-
meter leakage; verb-form footers instead.
- !expedition status defaults to a days-left + threat-label summary;
raw SU / threat-out-of-100 / zone-stack / roll-modifier moved behind
`!expedition status --debug`.
- !zone taunt/compliment help text dropped the "(mood −10)" / "(mood +5)"
numerics that turned the hidden TwinBee-mood mechanic into a min/max
knob.
- TwinBee pronoun pass: switched she/her to singular they on the two
surfaces I touched plus achievements.bj_beat_twinbee.
P1 — correctness/scale:
- adventure_shop curio purchase now guards the euro.Debit bool return
before inventory grant + pot cut; the GetBalance preflight isn't
enough since a concurrent blackjack/lottery debit can slip the balance
across BLACKJACK_DEBT_LIMIT between read and write.
- equipMagicItem reordered: remove inventory item BEFORE equip, with a
best-effort rollback if equip fails. The prior order left a dup
window if the inventory delete tripped on a transient DB error.
- magicItemsByRarityCache promoted to sync.Once — concurrent cold-start
loot rolls otherwise raced on the lazy assignment.
Stale-audit verifications (no code change needed):
- light / druidcraft / water_walk overlays already exist and win the
SRD merge — the broken raw text never reaches players.
- bootstrapPhase5BHPRefresh is already wired at adventure.go:228.
Deferred:
- combatantsForSession per-turn 6-load DB chatter (perf P1-A): touches
the hot combat path; needs its own test pass before shipping. Tracked
in memory at project_combat_session_cache_deferred.
go vet clean; go test -race ./... green (229s).

Per-zone resource registry (§3, all 10 zones) and full per-room harvest
layer wired into expeditions: !forage / !mine / !scavenge / !essence /
!commune / !resources. Auto-spawns a DungeonRun per region on
!expedition start, swaps it on !region travel, retires on
abandon/extract. Long rest at camp replenishes nodes across every
room and region. Reuses existing flavor.Harvest* / RichYield /
NodeDepleted / per-zone Harvest<Zone> pools.
Also clears two pre-existing test failures introduced by the E6c
flavor expansion (briefing substring list + combat-lift trial count).

L10 Use Magic Device: no scroll/wand item system to gate, so we proxy the
"now allowed to use magic items" fantasy as a small per-fight wand zap
(FlatDmgStart += 6) plus a +5% DamageBonus representing better tactical use
of magical implements.
L15 Thief's Reflexes: engine has no "extra turn round 1" primitive, so we
ride the AssassinateBonusDmg + AssassinateAdvantage channel (same one Gloom
Stalker's Dread Ambusher uses for bonus opener damage). Flat +8 on first
hit approximates one extra turn's hit; advantage on first attack covers
the "you swing first" piece.
3 new tests cover the L10 thresholds, L9 gate, and the L15 layer stacking
on top of L10. Full suite green.

L10 Improved Combat Superiority — superiority dice grow d8 → d10. The
two scalar maneuvers (Precision Attack +4→+5; Rally heal +4→+5) bump in
their Apply hooks; Trip Attack has no scalar to scale.
L15 Relentless — 5e regenerates one die when initiative is rolled with
an empty pool. Proxied as +1 max pool size (4→5), which gives the same
"always at least one die per encounter" guarantee across the long-rest
cycle without introducing per-fight regen state.
subclassResourceMax now takes level; initSubclassResources upserts the
max (and bumps current by the delta) so existing characters grow on
level-up. Hooked into the dnd_xp level-up loop so Battle Masters
crossing L15 see the new die without waiting for a long rest. 4 new
tests; no regression in subclass/resource/level-up paths.

Champion L10 Additional Fighting Style → +1 AC + 10% damage (Defense +
Dueling collapse, since one-shot combat can't surface a style picker).
Champion L15 Superior Critical → CritThreshold drops 19 → 18.
Berserker L10 Intimidating Presence → 2 rounds of SporeCloud miss
chance (Action-based fright proxied via the existing fog-cloud channel).
Berserker L15 Retaliation → +15% damage (reaction-strike average uplift,
since the engine has no reaction primitive).
6 new tests; full plugin suite green.

Evocation L7 Empowered Evocation adds INT mod (min +1) to Mage evocation
spell damage. Abjuration L5 Arcane Ward grants a 2×level HP buffer
absorbed before player HP, +prof at L7. Necromancy L5 Grim Harvest heals
2× spell level on spell-kill (3× necrotic) via post-combat hook.
Sculpt Spells / Potent Cantrip / Inured to Undeath skipped — no allies,
save-half is already uniform, and no necrotic enemy damage to resist.

Slots into the Phase 9 spell pipeline so an L5+ Rogue who picks Arcane
Trickster becomes a third-caster on the Mage list, INT-based.
- isSpellcaster(c) gate: full casters by class plus AT Rogue at L5+.
!cast / !spells now consult this; the cast class-gate also accepts
Mage-tagged spells when the player is an AT Rogue.
- subclassSpellSlots() / slotsForCharacter() / setSpellSlotsForCharacter()
layer subclass slots on top of the class baseline. AT pool: 3 L1 at
L5–6, 4 L1 + 2 L2 at L7+, +2 L3 at L13+ (third-caster table).
- spellcastingMod returns INT for AT Rogue.
- L7 Magical Ambush proxy: spellSaveDC bumps +2 once Rogue+AT hits L7,
standing in for "targets have disadvantage when casting from hidden"
since the one-shot combat layer doesn't model hidden state.
- ensureSpellsForCharacter bootstraps a Mage-list starter spellbook
(minor_illusion, shocking_grasp, magic_missile, shield, sleep at L5;
mirror_image + misty_step at L7+; hypnotic_pattern at L13+) and
refreshes the slot pool on level/subclass change.
- applySubclassChoice runs ensureSpellsForCharacter for AT so the
spellbook is provisioned at selection time (idempotent).
- !cast clamps upcasts to highestAvailableSlotForChar when AT, since
third-caster's slot ceiling lags behind the spell list.
Tests added: AT spellcaster gate (L5 cutoff, non-AT Rogue rejected), INT
mod, subclass slot pool by tier, L7 ambush DC bump, ensureSpells default
list (all on Mage list, slots correct), end-to-end !cast queues
magic_missile for AT Rogue, !cast rejects plain Thief Rogue.

Battle Master:
- New "superiority" resource pool (4/long-rest at L5), provisioned via
initSubclassResources at !subclass selection.
- Three armed maneuvers fueled by superiority dice:
* Precision Attack — +d8 (≈+4) to first attack roll
* Tripping Attack — enemy skips first attack (reuses Phase 9
SpellEnemySkipFirst)
* Rally — +(d8 + CHA) HealItem at <50% HP
- L7 Know Your Enemy proxied as +1 AttackBonus passive.
Assassin:
- L5 Assassinate: AssassinateAdvantage (re-roll first miss, take better
of two d20s) + AssassinateBonusDmg = level (5 at L5) stacked on top
of the Rogue's existing Sneak Attack auto-crit.
- L7 Impostor bumps the bonus damage by +3.
- L5 Infiltration Expertise → +5 Deception; L7 Impostor → +10.
Engine:
- CombatModifiers gains FirstAttackBonus, AssassinateAdvantage,
AssassinateBonusDmg.
- resolvePlayerAttack consumes each on the first attack only via new
combatState one-shot flags.
Tests added: 14 covering passive gating (BM L7+, Assassin L5/L7),
maneuver Apply flags, superiority pool init for BM only, !arm gating
across class/subclass for precision_attack, Deception bonus tiers,
statistical lift from FirstAttackBonus and AssassinateBonusDmg in
SimulateCombat.

First mechanical slice of the subclass system. Each subclass gets its L5
and L7 abilities wired through the existing combat engine + skill check
substrate; no new resource pools introduced.
Champion (L5/L7):
- Improved Critical: new Mods.CritThreshold lowers crit floor to nat 19+
in resolvePlayerAttack. Default 20 preserved for non-Champions.
- Remarkable Athlete: +½ proficiency bonus to STR/DEX/CON skill checks
via subclassSkillBonus, layered on raceSkillBonus.
Berserker (L5/L7):
- Rage: new !arm-able active ability gated to Berserker subclass via
DnDAbility.Subclass field. Reuses the Fighter stamina pool (3/long-rest
matches 5e's rage uses). On fire: +2 flat damage per hit, halve incoming
weapon damage, +50% damage approximation for Frenzy's bonus-attack-per-
turn (one-shot combat can't model that literally).
- Frenzy exhaustion: new exhaustion column on dnd_character; incremented
by persistDnDPostCombatSubclass after any rage'd combat. Decremented by
one per long rest.
- Mindless Rage: documented; charm/frighten conditions don't exist in the
combat engine yet, so no functional effect until P11 zone bosses land.
Thief (L5/L7):
- Sleight of Hand added to dndSkillTable.
- Fast Hands: +5 to Sleight of Hand checks via subclassSkillBonus.
- Supreme Sneak: advantage on Stealth (best of two d20s) via new
subclassSkillAdvantage hook in performSkillCheck. 5e's half-speed gate
dropped — we don't track movement speed.
Plumbing:
- applySubclassPassives layered after applyClassPassives in both arena
and dungeon combat bridges.
- DnDAbility.Subclass enables per-subclass gating; characterActiveAbilities
filters !arm and !abilities lists by both class and subclass.
- Existing !respec full-wipe also clears Exhaustion.
Tests: Champion CritThreshold gating across L4/L5/no-subclass; rage Apply
flag-set; rage probabilistic win-rate lift vs tougher enemy; exhaustion
increment only on raged combats; long-rest decrement; Champion bonus on
STR/DEX/CON only and only at L7+; Thief Fast Hands SoH-only; Thief
Supreme Sneak L7+ Stealth-only; statistical advantage roll lifts Thief
stealth average by ≥2 vs plain Rogue; !arm rage subclass gating; schema
roundtrip; characterActiveAbilities visibility.
