From 00e047db98d35aaaff3577a0edc145ac18fb2e67 Mon Sep 17 00:00:00 2001 From: alexpolo1 Date: Fri, 28 Aug 2026 00:35:31 +0200 Subject: [PATCH] feat(stealth): session rhythm, idle behaviour, and unproductive actions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per-action jitter cannot reach the strongest remaining signals. Averaged over a session jitter converges; what does not converge is a player who starts at the same hour, plays the same length, and never does anything without a purpose. Session budget (session_budget_h, default 6). Stops the bot after roughly N hours, rolled per run at 0.65-1.35x so consecutive days differ in length. NOTE: this genuinely stops the bot — set to 0 for unlimited. Scheduled breaks were already implemented at bot.py:1140 and simply switched off (break_length_m=0). Enabled at 120m/15m, and the interval and duration are now RE-ROLLED after every break: a break at exactly 120 minutes every time is still a pattern, just a slower one than no break at all. Per-game chicken threshold. A fixed 0.40 every game is a precise tell, but the randomisation is deliberately one-directional: it only ever RAISES the threshold, capped at base+spread. Lowering it would cost deaths, and an uncapped Gaussian tail reached 0.55 on a 0.40 base, which throws away healthy games. Rolled on the BOT thread and handed to health_manager through a setter — that thread is a read-only monitor by design and must not roll it itself. Idle cursor drift during long idles; between actions the cursor otherwise sits exactly where the last click left it. Bot thread only, screen-bounds clamped. Occasional unproductive town action (open inventory, close it) and occasional walking past an item the filter wanted. Both are rolled behaviours the bot has never had — it otherwise picks up exactly what the rules say, instantly, every single time. The town action is strictly best-effort and can never fail a maintenance step. All seven appear in the STEALTH> manifest, so any of them going inert is visible at startup rather than after 225 games. DELIBERATELY NOT IMPLEMENTED: pathing node jitter and route variation. Both would be good cover, and both are the system that produced Bugs 25 and 28, where a fabricated node position walked the character into the town wall. Nothing here touches the health manager's potion path or the attack sequences either — today demonstrated that cost twice. Tests: 20.
