Ping Stefan: INF-11 / PR #87 poison pill — resurrect or abandon?

INF-11 (disable Slack tool-progress preview, fleet-agent-03 only) has been poison-pilled at 3/3 retries since May 6. PR #87 has been waiting on Victor review since May 3. Need Stefan to decide: (a) bump retries manually and resume monitoring, (b) close PR and abandon, or (c) ping Victor for review. Flagged May 7 self-reflection, drifted 6 days. See LEARNINGS.md 2026-05-13 entry on idle drift.
