…/decay/bump New per-item demand multiplier table and AHBConfig plumbing: an in-memory itemDemand map (mirroring the price/count override maps), lazy decay computed on read (GetEffectiveDemandMultiplier), and BumpDemand to persist a bump. Not wired into the signal or the pricing path yet.
OnAuctionSuccessful now bumps the winning item's demand multiplier when dynamic pricing is enabled and the buyer is a real human: excluded via gBotsId for the bot's own characters, and via a LoginDatabase account username prefix check (cached in gAccountHumanCache) for mod-playerbots random bots, since there's no compile-time dependency on that module. Ambiguous/failed resolution never bumps.
AdjustPrices multiplies buyout/bid by the item's effective demand multiplier when AuctionHouseBot.DynamicPricing.Enable is set, after the existing moving-average and override clamps; the bid<=buyout guard further down in Sell() still runs afterward. LoadSharedOverrides now also loads and shares the demand map on startup and .reload config. New DynamicPricing.* options documented in mod_ahbot.conf.dist.

Stacked on #23 (retarget to merkerhood after that merges). Covers planned items 1, 2 and 10.
Adds a per-item demand multiplier on top of the ChromieCraft price baseline that reacts only to real human purchases and decays back to neutral. Design doc in
docs/superpowers/specs/2026-07-02-demand-multiplier-design.md.How it works
mod_auctionhousebot_demand(item, multiplier, last_bump), loaded with the other override tables and refreshed by.reload config.OnAuctionSuccessful, if the buyer is a real human, the item's multiplier bumps byBumpPercent(applied to the already-decayed value, clamped to[MinMultiplier, MaxMultiplier]) and persists.BotAccountPrefixes, defaultrndbot, case-insensitive) with a per-account verdict cache; ambiguous lookups fail toward no-op. The cache clears on reload so prefix changes take effect.1 + (stored - 1) * 0.5^(hoursSinceBump / DecayHalfLifeHours), computed on read, snapped to 1.0 inside 1%. No periodic job, no periodic writes.AdjustPrices()to both buyout and bid; bid <= buyout invariant preserved.Config (all in mod_ahbot.conf.dist)
DynamicPricing.Enable(default 0 — off),BumpPercent(8),DecayHalfLifeHours(72),MinMultiplier(0.5),MaxMultiplier(3.0),BotAccountPrefixes("rndbot"). All validated with clamp-and-warn.Out of scope (deferred): supply-side signal from human listings.
Compile-checked against the full core tree (RelWithDebInfo, gcc/ninja).
