- plan.md/.zh.md (+ plan-mode module JSDoc and README pair): the sole flush point is the prepended agent/step listener; prompt admission is pre-turn and never flushes — the pages had it backwards. - workspace.md/.zh.md: pending-mutation recovery deletes the marked table row — completing an interrupted delete but rolling back an interrupted create; 'completes exactly the marked mutation' oversold. - telemetry.md/.zh.md: delivery is best-effort with possible loss AND duplication, not at-most-once; TelemetryRecord.attributes JSDoc (source + both fences) now lists session.seed_length, which the coordinator emits for forked sessions. - Agent Note consequence bullet: nine pages cover ten services (storage owns two keys); client-modules.zh.md wire-single-source phrasing. Pairs re-recorded; plan-mode and telemetry suites green.
session/ — durable session data plane
English | 中文
The durable family around core/session's live in-memory service: the persistence seam with its storage backends and checkpoint policy, the projection seam that serves whole log-derived values, log-backed titles, and outbound session telemetry. All product packages. session-query/ remains a sibling group: the read/tool surface is consumed independently of persistence internals.
Persistence
Durable session persistence, semantic checkpoint policy, and the shipped storage backends.
| Package | Role | ctx key |
|---|---|---|
session-persistence/ |
Defines the persistence service and shared write coordination | ctx.sessionPersistence |
session-checkpoint-policy/ |
Applies semantic durability checkpoints | wraps ctx.llm and ctx.tools |
session-persistence-jsonl/ |
Persists sessions in JSONL files | registers on ctx.sessionPersistence |
session-persistence-sqlite/ |
Persists sessions in SQLite | registers on ctx.sessionPersistence |
The session-persistence decision records the persistence design.
Projection
Serves current, log-derived per-session state to client carriers.
| Package | Role | ctx key |
|---|---|---|
session-projection/ |
Defines and drives session projection units | ctx.sessionProjections |
session-projection-cache/ |
Persists and restores projection checkpoints | ctx.sessionProjectionCache |
Titles
Derives durable session titles from the session log, with an optional model-backed provider.
| Package | Role | ctx key |
|---|---|---|
session-title/ |
Owns title state, fallback behavior, provider registration, and refresh | ctx.sessionTitle |
session-title-llm/ |
Provides shared model-backed title generation | — |
session-title-first-message-llm/ |
Titles a session from its first eligible human message | registers on ctx.sessionTitle |
session-title-all-messages-llm/ |
Titles a session from all eligible human messages | registers on ctx.sessionTitle |
Deployments may register one model-backed provider; the service retains a deterministic fallback when none is present.
Telemetry
Projects session activity into outbound telemetry and delegates delivery to a configured reporting backend. The telemetry decision records the reporting boundary; the mode decision records immediate, feedback-gated, and disabled delivery.
| Package | Role |
|---|---|
session-telemetry/ |
Defines capture, redaction, projection, and live or on-demand backend delivery. |
session-telemetry-otel/ |
Delivers telemetry through OpenTelemetry logs in FULL, FEEDBACK_ONLY, or DISABLED mode. |
