# Memory OPD checkpoint staging

This directory is the machine-local staging area for checkpoints that will be
uploaded to Hugging Face. It is deliberately outside the `memory_OPD` Git
repository and must never be added to GitHub.

The layout is `RQ/method/backbone/retained-stage`. Baselines retain only one
completed `last` checkpoint for each RQ, method, and backbone. ElasticMem is
our method, so RQ3 additionally retains the SFT/GRPO stage boundaries and the
corrected-v3 continuation point.

Verify all files against `manifests/SHA256SUMS` after copying them to a new
server or before uploading them to Hugging Face. Selection provenance for the
node2 imports is recorded in `manifests/node2_selection.tsv`.
