docs/persistence-catalog/log-events.md enumerates every SessionEventMap member — the owning dsh-session vocabulary plus the dsh-compact and dsh-hook-protocol declaration merges — with payload, surface/log-only badge, JSDoc prose, and declaration site. scripts/gen-persistence-catalog.ts is a pure AST pass in the gen-cordis-catalog mold: verify-persistence-catalog (--check) joins doc-sync, so a stale committed catalog fails pre-push and CI. The walk enforces JSDoc completeness (every member needs description prose; @mode is rejected as a category error — log events do not dispatch on the cordis bus), derives the surface badge from the SurfaceEventType union with a stale-member cross-check, and hard-errors on duplicate declarations. Payloads render through the TypeScript printer so newline-separated multi-line type literals still emit valid one-line fragments. Documented the five previously JSDoc-less core events (turn/step boundaries, tool/call), removed the two stray @mode tags on the hook/* merges, and replaced the hand-restated event enumerations (session.md hook/* table, compact README table, hook-protocol README bullets, session README name-list — whose merge note had already drifted) with links to the catalog. RFC: docs/rfc/implemented/process/2026-07-04-persistence-log-catalog.md.
Packages
Harness packages, all under the @deepseek-ai/dsh-* scope. Each package is a Cordis plugin (microkernel-style): it exports either a default Service subclass or a functional plugin, declares its ctx key/events through declaration merging, and exposes extension points through ctx.effect(), ctx.on(), and ctx.waterfall(). Authoring conventions: AGENTS.md (subtree) and the root AGENTS.md § Conventions.
Hierarchy
Packages are grouped by modular role at packages/<group>/<pkg>/. The group directory is a pure container (no package.json of its own); the package name stays @deepseek-ai/dsh-<pkg> regardless of group. Each group README is the canonical per-package map — package roles, ctx keys, and the product-vs-support split live there, next to the code.
| Group | Role | Release expectation |
|---|---|---|
core/ |
Product API spine: session, system-prompt, tools, agent, and the concrete loop | Product — stable surface |
llm/ |
LLM capability family: the abstract service + provider adapters | Product — stable surface |
bash/ |
Bash capability family: the executor seam, a local impl, and the model-facing tool | Product — stable surface |
fs/ |
Filesystem capability family: the abstract seam, a local impl, and the model-facing file tools | Product — stable surface |
compact/ |
Compaction capability family: the abstract seam + a basic backend (tool deferred) | Product — stable surface |
subagent/ |
Subagent capability family: the provider-registry seam and the model-facing delegation tool | Product — stable surface |
web/ |
Web capability family: the abstract seam, search/fetch provider impls, and the model-facing web tools | Product — stable surface |
todo/ |
Todo/planning family: the model-facing todo_write tool (whole-list task tracking on the session log) |
Product — stable surface |
hooks/ |
Hook bridges + the shared Claude Code / Codex wire-protocol library | Product — stable surface |
session-persistence/ |
Persistence capability family: the seam + JSONL/SQLite backends | Product — stable surface |
ui/ |
Editor/client integration surfaces (the ACP bridge) + the app packages | Product — stable surface |
support/ |
Dev/test/example infrastructure (invariants, stdio UI, replay adapter) | Support — lower compatibility expectations |
util/ |
Low-level zero-dependency utilities shared across groups (the Branded<B> primitive) |
Support — small, stable, harness-dep-free |
The split is the point: a package's group says whether it is part of the product API or support/test/example infrastructure, so release and removal decisions do not treat every package as an equal public contract. New packages join an existing group; adding a new top-level group is a deliberate act (extend the group READMEs and this table).
Dependencies
The inter-package dependency graph is generated: docs/module-graph.md (pnpm run gen-module-graph, freshness-gated in CI).
The rule it must obey: extension plugins depend on interfaces, never on the concrete loop. dsh-agent-loop is swappable — UI/hook/tool plugins keep working against the dsh-agent vocabulary if the loop is replaced. The sanctioned exception is a composition/bundle package like dsh-agent-core, whose whole job is to assemble the concrete spine: it depends on dsh-agent-loop (and the other concrete spine plugins) on purpose. The rule constrains plugins that EXTEND the system, not the bundle that COMPOSES it — swapping the loop means shipping a different bundle, not rewiring every extension. A swappable capability splits into interface / implementation / consumer packages (the bash trio is the template — see capability seams).
Each package has its own README.md with purpose, service API, events, extension points, and deliberate non-goals (TODOs).
