// SRD-shaped stat blocks for the turn-based elite/boss engine.
//
// The auto-resolve path (SimulateCombat) keeps the simplified one-attack
// DnDMonsterTemplate shape — its Attack value is a gameplay-tuned average that
// bakes a creature's whole action into a single number, and the 2026-05-10
// rebalance is calibrated against it. Do NOT feed these profiles into
// auto-resolve.
//
// The turn-based path can afford canonical SRD multiattack *structure*: the
// player issues a command per round, so a creature making three attack rolls a
// turn is a tactical problem the player can answer (heal, control, flee) rather
// than an un-survivable spike.
//
// Balance basis (2026-05-14 tuning pass): raw SRD damage is calibrated for a
// 4-PC party and one-shots gogobee's single player — slice 1 shipped it
// canonical and it was un-survivable across every tier (marilith ~91/round,
// even Grol ~20/round vs a level-1 mage). So each profile keeps its SRD
// *shape* — attack count, names, per-attack to-hit, and the damage split
// between attacks — but the per-attack Damage values are scaled so the
// profile's round total lands at roughly 1.3x the creature's tuned
// auto-resolve Attack stat (dndBestiary). That 1.3x is deliberate: the
// 2026-05-10 rebalance calibrated the single-attack Attack stat as the
// gameplay floor, and turn-based fights should hit a little harder than
// auto-resolve to make the player's per-round agency (heal / control / flee)
// matter — but multiattack already raises hit reliability vs high-AC builds,
// and monster abilities now fire as riders on top, so the headroom over
// auto-resolve stays modest. Damage flows through the same calcDamage penalty
// formula as the Attack stat, so the two are directly comparable in scale.
//
// File is intentionally NOT dnd_-prefixed (see memory: no new dnd_* identifiers).

// SRDAttack is one attack roll within a creature's multiattack action: a d20
// to-hit and an average damage value for that single strike.
type SRDAttack struct {
	Name        string // "Longsword", "Bite", "Claw" — surfaces in the round log
	AttackBonus int    // d20 to-hit modifier; 0 falls back to the template AttackBonus
	Damage      int    // average damage for this single attack
}

// SRDProfile is a creature's full multiattack action — one SRDAttack per attack
// roll it makes on its turn. A creature with no profile registered makes a
// single attack using its DnDMonsterTemplate Attack / AttackBonus.
type SRDProfile struct {
	Attacks []SRDAttack
}

// srdProfiles is the turn-based multiattack registry, keyed by bestiary ID.
// Only elites and bosses that reach the turn-based engine need an entry; every
// other creature falls through to the single-attack template path. Per-attack
// Damage is tuned (not raw SRD) — see the balance-basis note above; the
// // -comment after each profile records the tuned auto-resolve Attack stat the
// total was scaled against.
