bpset

Overview ¶

Package bpset is the breakpoints row's one text form, shared by obsdb's two backends (obsdb.BreakpointSet): the set's JSON in the tools column.

• An empty set is "[]" — what PruneCommands' rules compare with, so a cleared set is pruned as before.
• A set with no provenance (no SetAt, no SetBy) is the plain array every Studio before U30.2 wrote.
• Otherwise an object: {"tools":[…],"set_at_ns":N,"set_by":"…"}.

Decode reads all three (a row an older Studio wrote reads with a zero SetAt and an empty SetBy).
