Persistent infrastructure for the Agent era.
Persisting contains pChronicle, which imports, browses, queries, exchanges, and serves durable Agent trajectory Datasets.
pip install persisting[lance]
pchronicle --versionThe rolling nightly build installs the same commands without a Rust toolchain:
curl -fsSL https://raw.githubusercontent.com/DeepLink-org/Persisting/main/scripts/install-nightly.sh | bashSee the installation guide for supported platforms and setup.
pchronicle onboard
pchronicle onboard query
pchronicle agent codex ./trajectory-data --ask "Which tools fail most often?"The onboarding flow creates a temporary example Dataset—no source checkout
required. pchronicle import accepts ATIF, ACTF, and OpenAI Messages;
pchronicle serve starts a loopback-only, read-only Dataset UI and API.
| Capability | Status |
|---|---|
| pChronicle local/S3 catalog, bounded SQL, analysis, find, import/export | Implemented |
| pChronicle loopback-only read API and embedded Web UI | Implemented |
| Queue and document Search | Separate stable capabilities |
| Tensor Memory / TTAS | Experimental |
- Choose a workflow — pick the entry point that matches your task
- Explore durable history — browse and query a trajectory Dataset
- Project architecture — ownership and delivery boundaries
Criterion.rs microbenchmarks and hyperfine lifecycle scenarios are compared
against main in CI; see the benchmark contract.
