Hypatia May 39ebd8f745 fix(session): close the review gaps the boundary opened
- `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.

Outbound session reporting: the telemetry seam plus its OpenTelemetry backend. The design — the boundary axiom (the harness's aspect ends at emit(); delivery is the reporting SDK's), the telemetry/record waterfall (deployment-mounted redaction rules; the seam ships none), the fixed chunk projection, the handoff cursor, and the operational-record channel — is pinned in the revival Agent Note.

Package Role
@deepseek-ai/dsh-session-telemetry The seam: capture points, projection, redaction, handoff cursor, ops signals, and the minimal backend contract (emit/flush?/shutdown).
@deepseek-ai/dsh-session-telemetry-otel The backend a deployment loads: the OTel JS SDK's log pipeline (LoggerProvider + BatchLogRecordProcessor + OTLP/HTTP exporter), configured verbatim through passthroughs.
