Release notes

Changelog

Deployment and operations

Pi has no install instruction and no stated Node floor: npm install succeeds on Node 20 and every pi call then crashes (Issue #1079; PR #1083)
install.sh does not install Pi: the install reports success and every tick then fails at the first Pi call (Issue #1080; PR #1082)

Documentation

Docs state only the bug shape for a ticket: a first-time user adding a feature has no stated form (Issue #1078; PR #1081)

Bug fixes

Runner logs ERROR command_failed on every tick when ORBI_ACTIVE_MILESTONE is absent (expected 404 logged at ERROR) (Issue #1085; PR #1086)
