Tianyi Cui c1d550de58 refactor(runtime): collapse speculative portability layers
Remove the one-consumer bounded-read primitive and shared terminal lifecycle controller, make terminal cleanup one awaited provider operation, and reuse one Code Runtime contract suite. Keep only reproduced cancellation and policy fixes; defer unproven replacement, prompt-attribution, and streaming-frame concerns to scoped markers.

lsp/ - LSP capability family

English | 中文

The language-server capability seam: an abstract LSP interface, a generic stdio provider, and the model-facing lsp tool. All product packages.

Package Role ctx key
lsp/ Abstract LSP seam (provider registry by branded id + extension mapping, per-query selection, vocabulary, LspError) ctx.lsp
lsp-local/ Generic multi-server stdio backend over ctx.fs and ctx.subprocess (JSON-RPC, transient-open queries) (registers providers on ctx.lsp)
tool-lsp/ Model-facing lsp tool (four operations, one-based UTF-16 cursor coordinates) (registers on ctx.tools)

The interface lives at lsp/lsp/. The seam exposes exactly four semantic operations — goToDefinition, findReferences, goToImplementation, hover — and no generic JSON-RPC escape hatch, so a provider swap does not change how the model asks for navigation and no protocol payload or unreviewed mutation reaches the model contract. Providers register capabilities, not tools; tool-lsp is the only owner of the model-facing name, schema, prompt guidance, and presentation.

See the LSP capability seam Agent Note for the design rationale, including why documents open transiently per query, why the stdio host consumes the shared filesystem/subprocess execution world, and why extension ownership is exclusive within one runtime.
