Method

A claim is confirmed when one source is TrackingTheSB or Ringwatchers, or when two independent sources agree. Any other single source stays unconfirmed. Hedge words demote a confirmed draft to unconfirmed and the build warns. Unconfirmed claims do not overwrite confirmed state. They are stamped UNCONFIRMED and drawn beside it.

Confirming handles

Hedge words

Lowercase may is a hedge. Capital May is a month.

Geometry

Rings are slots named by a claim. Empty stations are not drawn. Order is a sourced profile when one exists. Otherwise the tower uses a fixed layout order, which is not a sourced stack order.

A section move does not move the vehicle. The body stands where the latest confirmed whole-vehicle move put it, or where a sourced identify site seeded it. A stacked section follows later whole-vehicle moves. A vehicle with neither is unplaced. An unconfirmed body placement is hatched and stamped UNCONFIRMED. A candidate site stays beside the confirmed location.

Same-day confirmed claims that disagree stay unresolved. A later confirmed claim for that same key clears the active marker and keeps the earlier disagreement in the history. Identity fields use the same rule, and a blocked identify does not change the previous name or block. A sourced identify adds its site or region to the yard. An unconfirmed identity stays provisional.

Sources

Kinds

identify

Fields: subject

Required: subject

Records a vehicle, site, region, flight, hardware item, or slot name. A vehicle subject may carry a sourced site. That site seeds the body only when no whole-vehicle move has placed it. Identity does not draw a ring. Same-day disagreements on name, block, or other identity fields stay unresolved and keep the previous identity.

{"type":"identify","subject":{"type":"hardware","id":"og-can-crusher","name":"OG can crusher"}}

move

Fields: how, pieces, from, to

Required: how, pieces, to

Moves the named pieces. A slot piece changes that section only. A vehicle piece changes the body. A hardware piece changes that hardware. A section move never moves the vehicle. The example is the migrated Booster 24 A5:4 roll.

{"type":"move","how":"roll","pieces":[{"type":"slot","vehicle":"B24","slot":"A5:4"}],"from":"sfc","to":"mb1"}

stack

Fields: vehicle, slot, at

Required: vehicle, slot, at

Example shape, not a sourced claim. Marks one slot stacked at a site. After this date, a later whole-vehicle move carries the slot. The same calendar day does not, because order inside the day is not known.

{"type":"stack","vehicle":"B24","slot":"A5:4","at":"mb1"}

unstack

Fields: vehicle, slot, at

Required: vehicle, slot, at

Example shape, not a sourced claim. Returns a slot to crib at a site and stops it following the vehicle.

{"type":"unstack","vehicle":"B24","slot":"A5:4","at":"mb1"}

test

Fields: vehicle, test, at, result

Required: vehicle, test, at

Records a test. It does not move the vehicle or a section. The example matches the migrated Ship 42 cryo at Massey's.

{"type":"test","vehicle":"S42","test":"cryo","at":"masseys"}

schedule

Fields: flight, name, net, site

Required: flight, net, site

Sets a flight NET and site. name is required when the flight is new and must match the catalog name when the flight already has one. A later schedule can omit name. The example matches the migrated Flight 15 advisory.

{"type":"schedule","flight":"F15","name":"Flight 15","net":"2026-11-08","site":"pad2"}

assign

Fields: flight, vehicle, role

Required: flight, vehicle, role

Example shape, not a sourced claim. Assigns a booster or ship to a flight. It does not move hardware. A later assign of the same vehicle replaces the role.

{"type":"assign","flight":"F15","vehicle":"S42","role":"ship"}

note

Fields: at, about

Required: (none)

A sourced sentence. It does not move a vehicle or a section. When about is hardware and at is a site, the hardware is placed there. At least one of at or about is required.

{"type":"note","at":"lc39a"}

profile

Fields: vehicle, slots

Required: vehicle, slots

Example shape, not a sourced claim. Sourced stack order for one vehicle. Rings are still only slots with a move, stack, or unstack. Without a profile, towers use layout order and the legend says so.

{"type":"profile","vehicle":"B24","slots":[{"slot":"A5:4","order":40},{"slot":"A6:4","order":50}]}
