The built-client fixture served newly created Sessions with a control-baseline block as their list projections. Since SessionProjectionHints requires `kind`, the real client's applyListBlock would have hit assertNever on it; the created Session is live on the fixture Host, so its block is sequenced.
Merge master 7e2b049d8e2523127a3b4fba38cab4748ef0c72f, observed on
2026-09-19 at 07:38:37 UTC, into release/session-log-v4 at
c4663e8671e33bc2cfdbc868b0b18d979508d39b. Keep this base integration
separate from the five persistence repair PRs so their review diffs
remain focused and can be rebased without moving their fixes here.
Combine master's pin ordering and archived-session filter with V4's
parent-owned direct child catalog. Both grouped and flat sidebar rows
must pass the Session list to the V4 activity calculation; restoring
master's summary-lineage traversal would reintroduce the removed
subagent ownership and count unrelated descendants.
Keep master's removal of the archived-session settings page. Its only
release-side test change renamed a Session list fixture field, so no
runtime behavior is lost by deleting that obsolete test. Adapt the
release-side direct-child-status regression to the new row/filter
arguments and preserve its assertions.
Retain master's workspace ordering and row-motion documentation while
keeping the V4 child-catalog wording. Reconcile the generated bilingual
records against the merged documents. Frozen V0-V3 codecs, recorded
Session JSONL inputs, and the current V4 persistence schema are unchanged.

Merge master 0fdadce5189dcf13a00c2ed8293be95b9bb29c2c into the reviewed
Session V4 integration base. Preserve its V4 persistence and direct-catalog
subagent navigation while carrying forward current UI controls, decorative
icons, Desktop signing/runtime changes, and upstream tests.
Resolve lineage conflicts by retaining interaction-time catalog authority,
known-leaf handling and row order together with the shared status icons.
Keep both Desktop shell-routing regressions and one production route; master
now includes the route repair previously carried by this integration branch.
The full build, 41 documentation gates, two Desktop shell tests and 34 focused
Client lineage tests pass. Further built Web and packaging checks precede
publication. Preserve this pinned merge checkpoint before taking a newer
master tip, and propagate it through the reorganized feature stack.
