From 63d2f5281d23f313b9e31a7720de739f4ab6c20a Mon Sep 17 00:00:00 2001 From: jwinterm Date: Sat, 11 Jul 2026 20:02:39 -0400 Subject: [PATCH] =?UTF-8?q?feat(balance):=20per-network=20difficulty=20tun?= =?UTF-8?q?ing=20=E2=80=94=20cryptoType=20finally=20shapes=20size+monster?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Solves the two gaps the sim measured (edge undershot targets AND swung ~15pts across chains from identical dungeons because cryptoType was a dead parameter). Data-driven design (src/sim/calibrate.js, rewritten): the size-probe showed dungeon SIZE self-cancels as a house-edge lever — bigger map lengthens the run (timer edge up) but gives more room to dodge (monster edge down), flat ~60% until monstrous. So split the concerns: • SIZE ∝ √blockTime → PACING only (consistent run-length fraction of the block; GRIN sprint .. BTC epic), applied to every preset. Bot-robust. • MONSTER speed → the house EDGE lever (monotonic), solved per network for the casino/70% target only. difficultyConfig.js: NETWORK_TUNING table + applyNetworkTuning(), folded into getDifficultyConfig with precedence preset → tuning → env → customOverrides (so operator DUNGEON_*/MONSTER_* still win; NETWORK_TUNING_DISABLED kills it). Wired verification (explorer bot, 160 runs, 320ms): WOW/XMR/LTC/BTC/GRIN all land in a ~66-76% band around target (was 48-65%). BTC 48%->73% via 112x56 + 2.2x monster — on 10-min blocks the timer barely bites a 30s run, so the monster carries the edge (caps ~64% maxed: a real property of block-timed play). CAVEAT baked into the config comment: sim bots do not evade, so monsterSpeed is a STARTING POINT to retune with live telemetry; the sizeScale half is bot-robust. Deb is unaffected (WOW=reference scale 1.0; normal preset gets no monster tuning). test/networkTuning_ultra.test.js: size scaling, casino-only monster, block-time ordering, env-override-wins, kill-switch.
