jschoubben 2159375873 Merge the trunk: B0's facts and checking program carry the registry's steps (issue 1921, milestone 47/G D3-D11)
B0's shape wins: the running checker asks and records facts, the checking program
decides. The registry's types win: the rules and the program read the generated
checker contract and the domain SDK, and no mesh-sdk delivery import is left.
The registry's series, renames and unparsed seat definitions become facts with
their refusals as rules; the tagged versions ride on the case. The program reads
the heads' seat definitions through sdk/seatdefs and the running checker lays them
over its reader's list by seat, reading no file of the heads: the reader's list
is larger than a run input's bound.

// Command mesh-checking-program is the checker's checking program (novox/hq ADR 0644, ADR 0656; design 47's bootstrap
// delivery): built from a check's heads and run in the build seat's sandbox through the seat node-build-go's ask run,
// with no network and no bus account, it reads the check's facts from the file MESH_RUN_INPUT names and answers the
// verdict the judging rules give them, as one JSON line on its standard output (rules.Answer).
//
// mesh-checking-program -verdict
// mesh-checking-program -seats
//
// Asked -seats, it answers the seat list of the heads laid in the directory MESH_RUN_HEADS names (rules.SeatsAnswer).
// It refuses facts of a version it does not read, naming it, with exit 2.
