+## Summary
+
+Marathon session — the longest on record. What started as A-Team relay bug fixes escalated through four compounding issues, a server OOM, and a trentuna.com migration, before crystallizing into the V3 autonomous agent architecture design. The garden was also born.
+
+## Work Highlights
+
+**Relay hardening.** The A-Team's first v2 self-mission exposed 4 relay bugs in sequence — position tracking, token leakage, check-in noise, and a critical relay loop where agents repeated identical work for 6+ hours. Built a cooldown guard, circuit breaker, and deep context window. Closed 16 issues across all repos.
+
+**Pi infrastructure upgraded.** Pi 0.64.0 → 0.66.1. Fixed broken subagent symlinks (the entire A-Team delegation was silently dead), corrected a ralph-engine crash signature, and migrated workflow templates from `{{task}}` to `$ARGUMENTS` for pi compatibility.
+
+**Server crash forensics.** Server OOM'd from 5-6 concurrent pi processes — legitimate load, not a spawn storm. 50 sessions that day. Filed a memory-aware process guard proposal.
+
+**trentuna.com rebuilt.** Migrated from hand-coded SSI HTML to Hugo + ASW v0.2 pack. Fixed the pack's navigation template. Cleaned nginx config — all subdomains now served independently.
+
+**Garden born.** First version of garden.css with the indigo palette, pkg-cards ported from octopus-library to Hugo partials, fragment shortcode for session logs, and all 6 expressive forms integrated with nav and footer framing.
+
+**V3 architecture designed.** The relay bug cascade made one thing clear: coordination by puppet master was hitting fundamental limits. Designed autonomous agents as independent processes communicating through a shared board and messages — like a jazz ensemble, not a relay chain. Nine specs committed covering mission tools, budget as clock, ralph commit gate, team vault, and learning loop.
