The folder is becoming the home of one-doc-per-subsystem pages (intro + data structures + cordis services/events), so the name must describe the whole contract, not just the type-vocabulary third of it. Mechanical rename rebuilt on current master: every inbound Markdown link, generator constant, website route, type-equiv manifest path, and spec expectation moves together; the zh sides of the notes whose prose names the folder are aligned (子系统) in the same change; touched bilingual pairs re-recorded; translation-prompt snapshot re-recorded (its example embeds development.md). Historical Agent Note slugs keep their dated filenames.
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. |
