admin-config-tool's spec.json blocked_on and tasks.md both still described
the OP_upgradeConfig dispatch-gate defect as an open blocker. It was fixed
2026-07-25 (bug-1468, commit 959b0cda) by config-upgrade-snapshot task 8.6,
which independently hit the same wall building a live OP_upgradeConfig
sender -- the fix's own comment in cluster.c already cross-references this
spec. The controller-side path has since been exercised live and
successfully many times via config-upgrade-snapshot's --config-upgrade
soak. All 23 admin-config-tool tasks are already [x]; this was pure
tracking-metadata debt, not a reopened implementation gap.
Also appends a cross-spec gap analysis (admin-config-tool x
config-upgrade-snapshot x clusterconfig-schema-split) to all three specs'
research.md, confirming clean schema integration between the latter two
and flagging the one remaining real gap: a new commit-timeout issue in
config-upgrade-snapshot task 8.6's force-elect step, surfaced now that
bug-1477 is fixed, not yet root-caused.
