The indexer's tools bundle runs in a runtime of its own on its own account
(runs-as) and serves the first-view tools manifests, modules and verdicts,
each answering only the callers its manifest writes (ADR 0621 §1-§2, ADR
0622 §1), and the nine read tools of design 25 § 12.2. The process says each
change of its ten read states on the family indexer-views in its old streams
section (7 days, 256 MiB), with a mark per state the first view answers its
revision from, so a reader that takes the answer misses no event after it
(ADR 0615 §4-§5). The shared shape lives in sdk/views: event, answer, mark,
the emitter, the tools and the reader's follower.
Issue 1966.
