CHANGELOG (Unreleased) records libver_bounds and the 1.8 checks; known-issues moves "the writer does not produce output HDF5 1.8 can read" to Fixed (history) as an opt-in fix and keeps what is still open (Python 'w' has no libver, no pre-1.8 format, B-tree node filling vs libhdf5's chunk cache); README's capability table lists 1.8 output and v1 B-tree chunk indexes as written; BENCHMARKS gains the dated A/B of the two formats on the read harness (tank, 2026-09-28, under load), which is why the default stays the 1.10 format.

clawhdf5 documentation
Every document in the repository, one line each. Start with the README and the quick start.
Using clawhdf5
| Document | What it covers |
|---|---|
| README | What clawhdf5 is, the evidence, the feature matrix, install, quick starts, crate map |
| QUICKSTART.md | Working examples: HDF5 in Rust and Python, remote files, SWMR, NetCDF-4, h5rs, agent memory, CLI |
| USE_CASES.md | Where clawhdf5 fits, and when to use something else |
| agent-memory.md | The agent-memory store: search, durability, signing, modules, performance, schema, CLI, SQLite migration |
| known-issues.md | Open limits and fixed bugs, dated — read before relying on an edge case |
| openclaw.md | Why clawhdf5 is not an OpenClaw memory plugin, and what one would need |
| CHANGELOG.md | Every change by release, with upgrade notes; "Unreleased" is everything since v2.7.0 |
Evidence

|---|---|
| CONFORMANCE.md | Generated report: 697 public HDF5 files read by clawhdf5 and h5py and compared; the CVE corpus against h5dump and h5py |
