// server/sim/content/bonds/addon/meta.js — prep side of the add-on bonds (research 02 §3.14–§3.17, §3.20).
//
//   助力 deputShip  onPrepEnd: every currently active bond +`layer` (tier 2 = 3 助力 by name or elite state:
//                  +`more_layer`) — buff bond_activated_add_layer
//   远见 visiShip   every `layer` layers +`count` funds (bond_layer_gain_coin); first time at `layer1`: 远见 chess cost
//                  −`discount`; first time at `layer2`: every chess costs −`discount` instead (latched, permanent)
//   奇迹 miraShip   manual refresh with no free refresh pending → p = min(1, baseprob + prob·L) the next refresh is free;
//                  every 100 layers +20 funds (bond_layer_gain_coin). `probk` has no known meaning and is unused.
//   投资人          ×2 / ×3 "获得时" garrisons: EffectDispatcher.investRepeat (server/match/effectsMeta.js).
//   调和            +1 member count for core bonds: server/match/bondsMeta.js.
//
// Milestones read the persistent layers and pay only while the bond is active; payouts owed for layers gained while it
// was inactive ("无需激活" sources) are caught up the next time a hook sees it active (research 02 §8 Q7 [ASSUMED]).
// Funds earned after the prep phase ended (助力 / 寒檀 / 号角 … prep-end layers — the match wipes leftover funds right
// after onPrepEnd) are paid as pending funds, credited at the next round start, so "获得…资金" is never silently lost
// [ASSUMED]; `global:bondaddon_prepend` (first in every dispatch) marks the round whose prep has ended.
// 远见 discounts never push a price below 1 (research 02 §3.15 [ASSUMED]; a price already below 1 is left alone).
// Latched state lives in player counters (prefix `bondaddon:`); onPrice only reads them (pure).
