* feat(i18n): key translation pairing records by heading section Replace the whole-file blob hashes in *.i18n.yaml with one entry per heading section that still holds language-specific content, keyed by the English heading-slug path. Blocks identical across the pair (generated table rows, code blocks, shared regions) stay out of the hash, so edits to different sections and identical regenerations merge with Git's default text merge, including on GitHub. Remove the dsh-translation-pairing merge driver, its resolver command and installer wiring; gen-translation-brief recovers last-confirmed text from commit history. Migrate all active records, archive the superseded Agent Note, and record the replayed conflict reduction in the new one. * test(i18n): refresh translation prompt snapshot for the terminology note * feat(i18n): exclude only code blocks and generated regions from pairing records Replace byte-equality masking with an explicit rule: a record hash skips fenced code blocks and BEGIN/END GENERATED regions, the two kinds of content the pairing gate already requires to be identical on both sides. Move generated data into regions written into both pages: gen-config-catalog renders both languages and the record with per-package regions labelled by code identifiers; gen-module-graph keeps its table in a region; gen-doc-graphs splices the event matrix regions into the Chinese page. Add a generic region splice beside the region grammar.

| Package map for the durable session data plane: the persistence seam and its backends, checkpoint policy, projections, log-backed titles, and outbound session telemetry. | package-group |
session/ — durable session data plane
English | 中文
Summary
The session group keeps conversations durable, restores released log formats, and makes committed history available after restart. Its storage and checkpoint packages protect requests, tool side effects, and completed steps; projection packages derive client-ready values; title packages name sessions; telemetry packages report activity. Start with the shipped JSONL storage, then add checkpointing and only the projections, title policy, or telemetry your deployment needs. Each package README owns its guarantees and configuration, while a sibling query group provides independent read and tool access.
Table of Contents
Packages
The group splits into four families: durable storage (persistence seam, backends, checkpoint policy), projections, titles, and telemetry. Each package README owns its contract and configuration.
Persistence
| Package | Role | ctx key |
|---|---|---|
session-format/ |
Pure adjacent-format chain and artifact validation library | library — no ctx key |
session-format-v0-to-v1/ |
Frozen released-v0 decoder and identity migration into released v1 | library — no ctx key |
session-format-v1-to-v2/ |
Frozen released-v1 decoder and cardinality-changing Assistant-stream migration into released v2 | library — no ctx key |
session-format-v2-to-v3/ |
Frozen V2 decoder and system-prompt, envelope, and PTC migration into V3 | library — no ctx key |
session-format-v3-to-v4/ |
V3 identity migration and V4 codec with generation-aware delivery validation | library — no ctx key |
session-format-catalog/ |
Generated static catalog of shipped adjacent migrations | library — no ctx key |
session-persistence/ |
Defines the durable session-storage service and the shared write coordination every backend composes | ctx.sessionPersistence |
session-persistence-jsonl/ |
Shipped backend: immutable canonical generation filenames per Session with exclusive successor publication, optionally Zstandard-compressed | registers on ctx.sessionPersistence |
session-checkpoint-policy/ |
Makes model requests, top-level tool side effects, and completed steps durable before the next action | wraps ctx.llm and ctx.tools |
session-log-deepseek/ |
Uploads the incremental canonical log as optional official DeepSeek request metadata | contributes dsh_session_log |
Projection
| Package | Role | ctx key |
|---|---|---|
session-projection/ |
Defines and drives projection units that fold committed events into whole current values | ctx.sessionProjections |
session-projection-cache/ |
Persists projection checkpoints so cold reads skip full log loads | ctx.sessionProjectionCache |
session-stats/ |
Serves whole-log conversation counts and wall times through the sessionStats unit |
registers on ctx.sessionProjections |
session-turn-outline/ |
Serves the whole-log turn outline (turn, turn/start seq, prompt preview) through the turnOutline unit |
registers on ctx.sessionProjections |
Titles
| Package | Role | ctx key |
|---|---|---|
session-title/ |
Log-backed session titles with a deterministic fallback and one optional provider | ctx.sessionTitle |
session-title-llm/ |
Shared model-backed title-generation policy for the provider packages | library — no ctx key |
session-title-first-prompt-llm/ |
Titles a session from its first eligible human message | registers on ctx.sessionTitle |
session-title-all-prompts-llm/ |
Titles a session from all eligible human messages | registers on ctx.sessionTitle |
Telemetry
| Package | Role | ctx key |
|---|---|---|
session-telemetry/ |
Captures session activity and hands records to a configured reporting backend | ctx.sessionTelemetry |
session-telemetry-otel/ |
Delivers telemetry through OpenTelemetry logs in FEEDBACK_ONLY or DISABLED mode |
registers on ctx.sessionTelemetry |
Only one title provider may register at a time; without one, the title service keeps its deterministic fallback. The subsystem pages below are the backend-neutral references for each family.
