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.

Give the SDK JSON-RPC server a per-root tool filter and let deployments mark the configured persona as the complete system prompt. The checked-in minimal overlay now names only bash and str_replace_editor, so later global tools and unrelated guidance from dsh-base cannot appear implicitly.
Keep the shared SDK host services and packaged Web capability intact. Only workspace instructions, compaction, and the conflicting one-shot Bash row remain disabled. Unit coverage pins the configuration paths, and a real dsh profile smoke proves the assembled prompt and exact two-tool request.
Replace the TypeScript SDK's public arbitrary command/argv launch surface with the same-version dsh CLI, a named profile, ordered per-launch patches, optional process cwd, and explicit Harness home selection. Installed consumers use the built CLI; clean source checkouts use the package's src/bin.ts through an absolute tsx/esm loader and a source-only patch that omits build-generated Typert loading.
Materialize explicit or inherited environments at spawn time, keep profile-internal patches below caller patches, and resolve every caller-relative path before the child starts. The SDK subagent provider validates its optional CLI and patch files at plugin load and requires an isolated absolute child home.
Treat JSON-RPC initialize as the Loader-owned readiness point: Loader settlement joins entry imports, fiber lifecycle work, and synchronous effect registration, so the server needs no scheduler tick. A delayed profile entry registers a private adapter before initialize resolves, proving caller-supplied plugin routes are visible without fallback.
Update sdk-app ownership, server diagnostics, TypeScript SDK examples, nested-loader coverage, and session-upload replay layering together. The following commit contains only the regenerated SDK transcripts, keeping this API and lifecycle change directly reviewable.
