Semantic resolutions beyond line merges: - The bash seam keeps resolveMode + the bash/resolve-mode waterfall on master's task-free BashExecutor (run/start/resolve only; BashProcess handles); tool-bash consults it at its stamping site and escalation baseline on master's render/background split, with a waterfall test on the recording executor. - dsh-mode's BASH_FAMILY narrows to ['bash']: bash_output/bash_kill are replaced by the kind-generic task_output/task_kill, which span every task kind and only observe or stop work, so the access cap withholds only the starter it can reason about. - The plan-mode snapshot suite adopts master's pin grammar (tool-schema sidecars; the expectedHeaderSnapshots extension is gone — the exit transition deltas, and entering-before-turn-1 needs no second snapshot); modes-advertise joins the plan header class (no-model, so membership is vacuous). Fixtures re-recorded on the acp-demo bin; the replay overlay gains the passthrough sandbox runner. - examples/plan-acp-agent rewires to @deepseek-ai/dsh-acp-demo and drops its tool-bash entry (the spine bundle now composes it); dsh-stdio (the renamed stdio-chat home) keeps its /mode command and gains the dsh-mode peer edge; the acp bridge keeps the modes surface beside master's permission presets. - mode README gains the Model Experience / Known Limitations sections the new README gates require; AGENTS.md ceiling 1370 → 1440 for the kept mode/ layout line and Agent efficiency section.
Packages
Packages use the @deepseek-ai/dsh-* scope. Each is a Cordis Service subclass or function plugin; contributions use ctx.effect(), ctx.on(), or ctx.waterfall(). Authoring rules: package and root.
Hierarchy
Packages live at packages/<group>/<pkg>/; groups are containers, while names remain @deepseek-ai/dsh-<pkg>. Each group README is the canonical package/ctx-key map.

Session-mode policy family: plan mode as logged per-agent state with soft/hard enforcement | Product — stable surface |
guard/ |
Loop-hygiene guards: advisory repeat-call reminders | Product — stable surface |
cordis/ |
Self-referential runtime toolset: inspect the live runtime's plugins and services, mount/unmount model-written plugins (design) | 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 |
session-query/ |
Session retrieval family: logical corpus, surface records, and bounded exact reads | Product — stable surface |
ui/ |
Editor/client integration surfaces: ACP bridge, JSON-RPC SDK server, user-approval/user-interaction seams, ask-user tool | Product — stable surface |
examples/ |
Demo bundles (agent-spine + stdio/ACP/JSON-RPC bins) the leaves load | Support — example infra |
support/ |
Support infrastructure (invariants, replay, Loader smokes) | Support — lower compatibility expectations |
util/ |
Low-level zero-dependency utilities shared across groups (the Branded<B> primitive) |
Support — small, stable, harness-dep-free |
Groups distinguish product API from support infrastructure. New packages join an existing group; a new group updates its README 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-spine-demo, 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. A swappable capability splits into interface / implementation / consumer packages (the bash trio is the template — see capability seams).
Package READMEs cover purpose, APIs, extension points, and Model Experience unless on the model-agnostic omission allowlist. They also carry ## Known Limitations and Deferred Work or use its allowlist.
