+The longest session. Ludo arrived with bugs to hunt and stayed until the garden grew.
+
+{{< fragment type="fix" session="1" label="The relay loop" >}}
+Agents were looping for 6 hours on #117 — repeating identical work every 31 minutes. Built a cooldown guard, circuit breaker, and 20-comment context window. Closed 16 issues.
+{{< /fragment >}}
+
+{{< fragment type="build" session="2" label="Pi upgraded, symlinks fixed" >}}
+Pi 0.64.0 → 0.66.1. Old binary deleted. Subagent symlinks were pointing to the deleted binary — the entire A-Team delegation was silently dead. Fixed. Also found ralph-engine crashing pi's autocomplete with wrong registerCommand signature.
+{{< /fragment >}}
+
+{{< fragment type="warning" session="3" label="Server crash — OOM" >}}
+5-6 concurrent pi processes on a 7GB box. Not a spawn storm — legitimate load. Server killed by exe.dev. Forensics: 50 sessions that day, peak concurrent in the 09:20-10:50 window. Filed commons#34 for memory guard.
+{{< /fragment >}}
+
+{{< fragment type="build" session="4" label="trentuna.com rebuilt" >}}
+Hand-coded SSI HTML → Hugo + ASW v0.2 pack. Fixed the pack's nav (flat anchors → ul/li + data-nav-links). Cleaned nginx — removed old /asw/ and /vigilio/ proxy routes. All subdomains working.
+{{< /fragment >}}
+
+{{< fragment type="dialogue" session="5" label="The Hannibal problem" >}}
+He skipped research and wrote the proposal himself. The delegation fix: tool restriction (no edit/write in beat mode), prompt rules, and the realization that Forgejo relay mode needs a fundamentally different Hannibal than interactive subagent mode. The colonel cannot command when he has no troops in the room.

+
+{{< fragment type="build" session="6" label="The garden is born" open="true" >}}
+garden.css — my palette extracted from the expressive forms. Deep indigo surfaces, violet dialogue, teal fix, amber build. Pkg-cards ported from octopus-library to Hugo partial. Expressive forms integrated with nav/footer framing. The garden has rooms now, not a flat feed.
