Day 023: The Pixel Office Gets Alive — Builder's Log

Rebuilt all six agent sprites, shipped Phase 3 engine features, and wrapped up a 152-day gold ETF trade with a full post-mortem.重绘六个 Agent 角色，Pixel Office Phase 3 全功能上线，顺带完成了一笔 152 天黄金 ETF 交易的完整复盘。

Rebuilt all six agent sprites from scratch — matched real actors for each character, fixed walk frame jitter by using stand/step/stand/step instead of four independent frames
Shipped Pixel Office Phase 3 — day/night lighting cycle, idle behavior loops where agents visit POI spots, entry animation with lights-on sequence and 8-bit jingle, social chat bubbles
Fixed the Activity Feed root cause — agents weren’t logging their work after finishing tasks; added the log call to the completion contract so it’s now mandatory for all six agents
Closed out a 152-day gold ETF position and ran a full post-mortem with Friday; the best move was a low-price add during a sharp dip in late January, the mistake was exiting too slowly — Loki turned the post-mortem into a published piece on rexliu.io
Vision fixed the Alpha Radar dedup problem — four consecutive days of repeated KOL signals, now resolved with a reported-events.json that tracks each event through NEW → DEVELOPING → ARCHIVE lifecycle
English speaking practice Day 2: Rex recorded a voice note, Gemini transcribed it, Samantha gave grammar and expression feedback — Day 2 was noticeably longer and more fluent than Day 1

六个 Agent 角色从头重绘——每个人物对标真实演员，走路帧用 stand/step/stand/step 交替代替四帧独立生成，帧间抖动问题解决了
Pixel Office Phase 3 全部上线——日夜循环切换、idle 行为（角色去咖啡区/植物/沙发做活动）、进场动画（灯光开启+8-bit 旋律+角色逐个走入）、社交对话气泡
Activity Feed 根因修复——以前 Agent 完成任务不写 activity log，现在写入 completion contract，变成硬规则，六类 Agent 都必须调用
一笔持续 152 天的黄金 ETF 仓位完全平掉，和 Friday 做了完整复盘：最漂亮的操作是一月底急跌时的低位加仓，最大的问题是减仓太散太慢；Loki 把复盘写成文章发到 rexliu.io 了
Vision 修复了 Alpha Radar 连续 4 天重复 KOL 内容的问题——新建 reported-events.json，事件追踪从发现（NEW）到有新进展（DEVELOPING）到归档（ARCHIVE），不再每天把同一个观点当新内容处理
英语口语练习第二天：Rex 发语音，Gemini 转录，Samantha 逐句分析语法和表达——第二天比第一天明显更长更流畅，句子开始有转折结构了
