- `SessionSummary.updatedAt`'s wire doc still said "Persisted file mtime",
which stopped being true for attached sessions.
- The core invariant let `session/inherited` fall through the merge-extensible
default. It is core-owned, so it gets an explicit case; an unbalanced seed
legally places it inside an open turn, which the relation permits.
- The Agent Note claimed the boundary reaches disk via `live.pending`/
`scheduleDrain`. Verified false: the constructor append precedes `enter()`,
so it never publishes on `session/event` and rides the creation seed instead.
Attaching is therefore a write where none happened before — recorded, since
only `load()` stays a pure read.
- The deferred-index proposal asserted this change documented the cold-mtime
skew on `dsh-host-apiproxy`. It did not; the README entry now exists.
- `firstLiveSeq`'s firehose gap runs through its own seq, not below it.
- The boundary is not always at `firstLiveSeq` (the idempotence guard), so
consumers scan for the last one.
- `lastActivityTime` excludes by type, so a pickup time still leaks onto a
synthetic closer when a boundary ends an open turn. Documented.
- Pin the fork claim end-to-end: a child inherits a still-running parent's
open bracket below its own boundary, while the parent has none. Fails if the
write moves back to the load path.
- Fix the telemetry title that contradicted its own assertions.
The `/status` call site cannot be pinned the way the other two are: the
command appends its own `command/run` before rendering, so the boundary is
never the log tail there. Its fixture now at least renders over a
boundary-bearing log.
