Investigation Notes (2026-05-22)

• Flag 29 (canonical calendar): Provisionally iCal. Cluster with other calendar items (Entries 13d, 12, 8). Full process work (needs → design → harden) still required before final ecosystem shape is known.
• Flag 30 (sync direction): Don’t know yet. All the process work needs to happen first — understand needs, outline requirements, design tools, harden.
