Old runtimes meeting a newer session format now fail loud instead of misreading: version refusal names the direction (newer: upgrade the harness; older: no upgrade path) and points at the raw JSONL log, and an event type outside the generated known vocabulary refuses resume unless its envelope carries the new ignorable: true marker (default: required, so a forgotten marker over-refuses instead of silently resuming a gutted session). gen-persistence-catalog now also emits KNOWN_SESSION_EVENT_TYPES; SQLite stores the marker in a dedicated column (SCHEMA_VERSION 15). The versioning design (monotonic integer, n->n+1 upgrader chain, migrate-on-continue) is recorded in the session-log-version-mechanism Agent Note.
headless-agent
English | 中文
This directory owns the replay and real-model test composition for a headless coding agent: DeepSeek V4 + local bash and filesystem tools + subagent delegation + workflows and fresh-agent Ralph iteration + todo_write + JSONL persistence. It explicitly mounts the shared agent spine, one root agent, persistence, and checkpoint policy; it is not a second product entry point.
Run it
# repo root .env (gitignored) or exported env:
# DEEPSEEK_API_KEY=sk-…
# DEEPSEEK_BASE_URL=https://… # optional; defaults to the public API
pnpm run dsh --profile headless "fix the failing test in this workspace"
The product command is dsh --profile headless: it accepts one nonblank task, creates and persists a fresh session, prints the final assistant text, and exits. The root demo:headless script is only an alias of that command.
Snapshot suites run this directory's configuration through tests/fixtures/headless-driver.ts, an unexported test-only process that emits canonical session events as JSONL before its result record. That stream is test infrastructure, not a supported CLI output format. Child sessions surface only through parent tool events and results.
E2B POC overlay
e2b.cordis.yml replaces the local filesystem and subprocess providers with one shared E2B sandbox while retaining dsh-bash-local and the same model-facing tools. Put E2B_API_KEY beside DEEPSEEK_API_KEY in the gitignored root .env, then run the credential-gated live composition, which drives FS, Bash, PTY, and LSP in one sandbox and proves final deletion:
pnpm exec vitest run --config vitest.e2e.config.ts packages/e2b/e2b/tests/composition.e2e.ts
The overlay creates the same absolute cwd inside the sandbox, but it does not upload or mount the host workspace. File and Bash mutations exist only in E2B; Cordis, model calls, agent/session state, session logs, skills, and SDK buffers remain on the host. The composition kills its sandbox on timeout and disposal. It is a provider-composition POC, not a whole-harness migration or a workspace-sync feature.
Advanced configuration
advanced.cordis.yml adds Code Mode and the Cordis tools to the test composition.
