Merge master 0e9385ad8b9e75146f4baec2e731dd961f11c87c, observed when
this final integration step started, into the merged V4 release branch.
Keep the complete upstream history and do not advance to later master
commits during finalization.
Bring the Web trust-domain and relative-route handling, plugin install
cancellation, and npm registry mirror configuration into the common
release baseline. Retain the V4 codecs, producer-source policy,
parent-owned catalogs, and fork/migration behavior from the merged stack.
The merge needs no manual conflict resolution and changes no Session
JSONL inputs, snapshot generations, format packages, or persistence
schema/history files. This checkpoint precedes the separate V4 freeze
and audit fixes so each change keeps its own rationale and validation.
Merge a2acc7d3eb620bb52f09f7ea3b5a3a1c23353e18 after preserving the earlier
master checkpoint and its successful CI. Carry current provider input-history
handling, UI controls, agent targeting, and runner-concurrency changes into
the integration base without changing the Session migration feature layers.
Keep durable direct-child catalog semantics alongside the upstream running /
inactive vocabulary. Resolve the snapshot description conflicts by retaining
that upstream status text and the existing descendants-only diagnostic rule;
the source and all 53 JSON tool descriptions agree. Preserve parent-session
availability handling with the upstream stale-blank and batched-history fixes.
The merged application builds, all 41 documentation gates pass, and focused
provider, tool-control, and Session Controller tests pass (98, 29, and 125).
Recorded input changes come from master: one refreshed v3 list-agents sample
and three new v3 scenarios; no migration bumps an existing snapshot generation.
The install dialog folds a registry control beside the guide: the
official registry, the mirrors the Host configured, and a typed
address, remembered in this browser and passed to the check and the
run. The installing screen names the registry the Host moved on to,
each pnpm run carries its registry, and a failed run names every
registry asked, or the host a git or tarball spec could not reach,
with a shortcut back to the registry options. The Host answers the
spec's own host and the registries it asked so the dialog can say so.
Also documents the registry plan in the package READMEs, the boot
subsystem page, the catalogs, and an Agent Note; pins the flow through
a real Host/browser e2e and refreshes the tool-schema snapshots.
