- Translate README.zh.md's Model Experience body and KV Cache line, which
were left verbatim in English.
- Convert half-width punctuation to full-width across the README.zh.md
Known Limitations bullets and the entire Agent Note Chinese side, per
docs/i18n translation-rules.md Typography (MUST use ，。：（）in Chinese prose).
- Re-record both README and Agent Note i18n.yaml pairing hashes.
- Reword the workspace-constraints extra-files comment: this layer's py/
ships only the wire-protocol mirror; the spawned bootstrap arrives later.
- Drop the unused @deepseek-ai/dsh-code-runtime dependency: this layer
imports nothing from the seam (protocol.ts has no imports; the invariant
companion uses only cordis and dsh-invariants). The backend-core PR
re-adds it when PythonCodeRuntime consumes the seam. Fixes knip.
- Point the Agent Note's cross-reference to the seam note at the English
target on both language sides, per the bilingual-pairing contract (only
the language switcher flips to .zh.md). Re-record the sidecar.
- Add the Known Limitations section both READMEs require, covering the
cross-language guard's scope and the deferred runtime implementation.
- Regenerate the module graph for the dropped dependency edge.
Introduce @deepseek-ai/dsh-code-runtime-python with the versionless
JSON-lines protocol between the Node host and the CPython subprocess:
the host-side hostile-frame codec (validateChildFrame, encodeJsonPlain,
checkDoneValue, hasUnsafeIntegerToken, hasNonLosslessNumber,
logTruncationMarker) and the Python-side wire-vocabulary mirror
(py/protocol.py).
This is the protocol layer of the code-runtime-python stack, split from
#436 and based on the multi-language seam extension. The PythonCodeRuntime
implementation and its Python JSON codec land in the backend-core PR on
top of this branch.
Ship the minimal buildable package skeleton (package.json, tsconfig,
tsdown, barrel index, invariant companion, bilingual README) because the
workspace-constraint, coverage, and invariant-topology gates require the
package to exist and build the moment its directory does; the backend-core
PR extends those files rather than creating them.
Align py/protocol.py with src/protocol.ts (the round-12 review of #436
found LogMessage.truncated, DoneMessage.error.kind, and Namespace.errorClass
stale) and guard the two runtime-executed surfaces (PROTOCOL_FD and the log
truncation marker) with a real-python3 cross-language mirror e2e test.
