2025-12 OverlayPlugin/cactbot monthly summary focusing on key achievements, features delivered, and quality improvements. Key features delivered: - Enhanced encounter triggers, timelines, and reporting for raids and trials. Consolidated and expanded triggers for encounters (FATE monsters, Tsukuyomi Unreal, Mistwake Dungeon, Lifereaper, etc.), improved timeline handling and synchronization, clarified timeline syntax, and added encounter reporting and raid emulator support. - Expanded encounter coverage with Tsukuyomi Unreal, Mistwake Dungeon, and timeline syntax/documentation improvements (array syntax in timelines). - CE-related tooling and data enhancements: basic support for CE-based encounter detection/reporting; CE info generation from xivapi; support for sheets with subrow_id; and raid tools integration for critical encounters. - Raid emulator and testing improvements: added support for critical encounters in the raid emulator and improved synchronization logic for CE timelines. Major bugs fixed: - Fixed incorrect "+Follow Dash => Get Behind" trigger duplication and adjusted trigger placement to avoid double alerts (#881). - Fixed OC CE timelines if already in combat by widening the initial re-sync window (#899) and ensuring timelines align after early combat entry. - Fixed resources example for tankBuster() response code capitalization (#869). Overall impact and accomplishments: - Significantly increased reliability and coverage of raid/trial encounter automation, enabling raiders to plan and react with more accurate timelines and reporting. - Improved solo play experience through better triggering and timing decoupled from combat start. - Reduced maintenance risk via cleaner syntax rules, consistent naming, and better tooling around CE data. Technologies/skills demonstrated: - TypeScript/JavaScript code quality, timeline parsing, and trigger logic. - xivapi integration for encounter naming and data mapping. - CE-based encounter detection and reporting, and raid emulator integration. - Testing and live-validation strategies in low-population instances and edge-case scenarios.

November 2025 highlights Arkveld Encounter Timeline Data in OverlayPlugin/cactbot. Delivered a new timeline dataset for the Arkveld encounter in Windward Wilds, outlining abilities and mechanics to guide players during the fight. Implemented as data-driven timeline cues integrated with the existing raidboss timeline framework. This work improves raid guidance, reduces learning curve for new players, and supports consistent outcomes across runs. No major bugs fixed this month. Business value: clearer guidance during high-stakes encounters, faster onboarding, and more predictable raid performance. Technologies/skills demonstrated: data modeling for timelines, JSON/TypeScript-based timeline scripting, version-controlled feature delivery, and cross-team collaboration with raid content owners.
