Two safe-integer timestamps can differ by more than 2^53-1 (e.g. MIN_SAFE_INTEGER to MAX_SAFE_INTEGER-1), so the dt subtraction rounds and the packed row decodes to a timestamp one off the original -- violating the codec's lossless contract. Unreachable from a real clock (the gap needs ~285k years) but reachable from hand-written fixtures, and the decoder accepts hand-written rows. continues() now refuses to extend a run across such a gap (the check is exact both ways: an in-range true gap subtracts without rounding and passes; an out-of-range one rounds to an out-of-range value and fails), splitting the run instead -- whitelist philosophy, compression lost, data never. The decoder tightens to match the encoder's image: time0 and dt must be safe integers, and reconstructed member seqs/times must stay in safe range, so float reconstruction is exact wherever validation passes. The round-trip property now draws times from the full safe-integer range (it previously generated only small gaps, which is how this escaped); the bot's counterexample is pinned as an example test.

DeepSeek Harness
English | 中文
The DeepSeek Harness SDK is a plugin-based SDK for building agent harnesses.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
pnpm install
pnpm run test # vitest
pnpm run demo:repl # REPL agent demo (needs DEEPSEEK_API_KEY)
pnpm run demo:acp # ACP server agent demo (needs DEEPSEEK_API_KEY)
For humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design and documentation graph index before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
