From 05ad5fae86c0c863ca36e13ab656738dd41123b2 Mon Sep 17 00:00:00 2001 From: autocommit Date: Thu, 4 Jun 2026 16:10:58 -0700 Subject: [PATCH] feat(p3-10b): wire lair siege into the live turn loop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit tick_siege/decay_siege + SiegeState (persisted on GameState::siege_pressure) shipped earlier but were dead code — never called from the turn loop. This adds the per-turn lair-siege phase + a data-driven config loader. - mc-turn/src/lair_siege.rs: LairSiegeConfig loader from lair_combat_modes.json::siege.siege_pressure (per-tier resistance + tuning, Rail 2 — consumes authored data, no fabricated per-lair siege_resistance); tick_one_lair pure helper; LairSiegeEvent. - processor::process_lair_sieges (Phase 5d in step): iterates siege_pressure, detects besieger adjacency, ticks/decays, surrenders + rolls loot + drops the entry, logs to TurnResult::lair_siege_log. authored_lair_siege_config() embeds the JSON build-time + OnceLock (same pattern as encounter_rates). - resolve_lair_combat Siege arm stays single-shot-NotImplemented BY DESIGN (multi-turn state can't flow through LairAssaultParams -> AssaultOutcome; same precedent as resolve_raid's separate entry) — doc'd to point at the live per-turn phase. Honest boundary: nothing in the live loop INITIATES a siege yet (a player picks Siege via the GdLair bridge / UI mode picker — godot-ui follow-up that owns GdLair::begin_siege). The phase is exercised by tests + the future bridge; mechanic is live, initiation is the remaining dependency. GDExt begin_siege/siege_pressure bullet stays open (K=4/5). Tests (apricot): lair_siege lib 5/5 (incl. named pressure_accumulates_then_ surrenders + pressure_decays_when_unattended) + config loaders 3; integration lair_siege_phase 4/4 (through processor.step + save/load round-trip); mc-turn 240 lib, mc-combat 143 lib, serde_roundtrip 6/6; cargo check --workspace 0.
