A cursor-less adoption (process restart + resume, fork, seam-module reload) replayed the session's full log from seq 0, re-exporting history that already left the process — a resume re-billed its entire stored log on every restart, and a fork re-shipped the parent's prefix under the child's id, doubling query-time counts on OTLP backends with no native ingest dedupe. dsh-session now exposes the fact the constructor already validated but discarded: Session.firstLiveSeq, the constructor-seed length — the first seq appended in this process. header.seedLength cannot serve here: it is the durable fork-lineage boundary, and a resumed session's constructor seed is its full stored log while the header keeps the original fork value (llm-replay and session-query-sqlite depend on that meaning). Constructor seeds also never publish on the session/event firehose, so adoption replaying them was inconsistent with the system's own publication semantics. Adoption's cursor-less fallback starts at firstLiveSeq; seed events still feed the chunk projection, so mid-step continuations re-drop after a resume. Fork streams are no longer self-contained: records now carry session.seed_length (with the existing session.parent_id) so receivers stitch the child's stream onto the parent's. Accepted cost, consistent with at-most-once delivery and recorded in the revival Agent Note: a resume no longer backfills records a previous process failed to deliver — a deployment with that requirement needs the deferred outbox, not replay. Pinned red-first: seeded adoption exports nothing (assertion reversed from the prior seed-readback test, obsolete behavior changed with its test), resume-shaped seed rebuilds the projection without exporting, and fork records carry the stitch attributes.
telemetry/
English | 中文
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/redact waterfall (deployment-mounted 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. |
