AnswerSeat checks a call's caller against the seat's definition its caller
reads from the seat list it follows (A-186), refusing every caller while the
list is unread. The assigner (mesh-wants input), the builder (mesh-builds
reserved) and the indexer (mesh-catalog input) hand it the definition their
seat list holds once heard; the pipeline runner, which followed none, follows
one over its calls connection and hub, read again once its events are live,
and its manifest invokes seat-definitions and consumes the list's two events.
The runner's and the indexer's integration beds answer the seat list, and the
indexer's input test calls with a caller the bus proved (A-179).

The validation run's answer is read from the step's end through steprun's

The program puts the validation's run ask on node-build-go's check queue
under its own asker and hears its end on step-ended; the manifest invokes
seat:node-build-go.accept.check. The revision validated is the branch its
merges landed on (the merged message's base, else the trunk), never the pull
request's branch. take-in.pending may name a refusal or why the revision
could not validate instead of the build it waits for. The whole case runs a
stand-in build seat: an accepted revision is taken in as before, by one ask
whose job names the indexer entry's repository, path and the revision's
head and no heads; a merge whose changed manifest gains a problem stays
pending, refused naming it.

The indexer hears the runner's run-started and pipeline-ended on their own streams and writes candidates.run-<id>:
one pull per member, its repository and directory from its registration, its manifest and fingerprint from a take-in
of its commit read through the seat git, over its branch's revision view when its registration watches the branch,
else the trunk's. The state runs keeps each run's members and ended modules, so a restart between two ends still
drops the candidate. The try candidates, the checker's checks consumer, checker_tries and the three try tools go;

A member a running put in a set leaves it also when the want of that node and module is removed (the node left or the module was

The indexer consumes the seat mesh-wants' wanted (on wanted.<node>.<module>, kept last per subject: the seat's definition gains
the two tokens and the keep) and the node-engine seat's running, each read whole at its start and followed; it keeps in the
old state section named (max-mib 4) one key per fingerprint with its set of <node>.<module>, written by compare-and-set. An
entry object is removed only when no kept revision lists it and its set is empty, and not before both streams were read and the
sets reconciled; its entry-index key goes with it. indexer_entries reads the set, indexer_named_drop removes one member by
hand (class act, said in the hand-act log first).

The indexer's CAS Findings store is the held writer through the small FindingWriter interface (Write, Clear, Held): the
unread-call, accepted-unsaid, seat-definition and out-of-step findings are raised and cleared through it, the unsaid ones
read from Held. followAssignments follows the assigner's assignments through the module's ProcessReader (the reader raises and
clears the first view's finding), the emitter and the family-not-heard finding write through the same writer, and the
view-waits finding of the seat git is written by hand through Write and Clear (A-28). The old resolved words go (A-22).
