Add @deepseek-ai/dsh-agent-model. It provides ctx.agentModel
(resolveForNextStep, select, applyConfiguredRoute) and owns the
modelSelection projection, which the Agent registry no longer registers.
dsh-agent-loop now injects agentModel; the base and SDK-minimal bundles
and the Python SDK runtime include it.
The provider keeps the projection registered until consumers that are
still unloading finish their cleanup. The model-switch notice becomes an
opt-in per-Agent plugin at @deepseek-ai/dsh-agent-model/notice, and
agent/request now also rejects reasoning-effort changes after step
preparation.
Mount the provider in every composition that loads dsh-agent-loop, and
update consumers, the switch-notice snapshot driver, docs, and the
upgrade guide.
A profile installs @deepseek-ai/dsh-experimental-browser-use-runtime from npm
beside the dsh installation, and that package declared @deepseek-ai/dsh-scope
and @deepseek-ai/dsh-mcp-client as dependencies, so the install carried its own
copy of both.
dsh-scope mints its scope-tag symbol per module instance, so the copy's
createScope tags a context the host's scopeOf cannot read. Every Agent's MCP
tools then registered in the global tool layer: the first Agent succeeded and
each later Agent's tool synchronization hit a name conflict, which
failOnStartupError turned into a failed creation.
Both are now peer dependencies (plus dev), which is how every other consumer of
ctx.tools and dsh-scope declares them and how a profile install reaches the
installation's single instance through the profiles module fallback.
schemastery stays a dependency: it carries no instance-local state.
Fixes#4573
Represent tool results as tool-role messages and migrate released wrappers
without losing outer own JSON fields, call identity, error state, or writer
field order. Refuse nested or wrapper-only information that has no lossless
current representation before successor publication.
Validate current event relationships directly instead of projecting V4 data
back into V3. Keep lifecycle, PTC, title/command, compaction, system-field and
retired-syntax checks on catalog restoration and ordinary JSONL opens. The
Worker JSON equality helper must inspect own keys so it cannot admit PTC
arguments that Node rejects.
Keep the source role change, required native admission and consumer fixture
updates in one complete review layer. Explain shared-type changes in the
persistence record and the native reader rationale in its existing note.
Use checked branded fixture identities and discriminant narrowing instead
of unknown double casts; fixture values and assertions remain intact.
This recomposes the original tool-role work by _Kerman with the independently
validated migration and admission repairs by Tianyi Cui. Frozen generations
and snapshot input version selection are retained.
