RustFS's S3 Select infers an object's schema from its first 1000 rows: a where
field absent there is unbound (EvaluatorBindingDoesNotExist), and a column null
in all of them but set later fails the whole object (JSONParsingError, measured:
999 leading nulls answer, 1000 fail). plane/memory.py now declares per kind the
fields a where may name (QUERY_FIELDS: facts candidates_digest, verdict
candidate/final, example profile, plus the ROW_FIELDS every row has) and writes
their union on every row at write time as strings, "" where one does not apply
(null measured to break). rows() refuses an unknown kind, an undeclared where
field and where = null before any read. `ousast plane memory-normalise
[--store URL] [--dry-run]` rewrites pre-rule rows once, idempotently, with
counts. The fake object client mimics both RustFS failures.

Maintainer decisions 2026-10-02: "it has the featurs. fallback not desired" and
"Admin sets it once; agent verifies".
- MinioStore never configures its bucket: configure()/enable_versioning()/
expire() are gone; the client protocol only reads versioning and lifecycle.
- verify_bucket() runs when a MinioStore is opened (once per process per
store): versioning Enabled, an enabled lifecycle rule expiring <prefix>/runs/
(none expiring the whole store), S3 Select answering a probe, object tags
readable. Every missing piece is listed in one MemoryStoreError with the
aws-cli admin command or the permission to grant.
- No S3 Select fallback: a server without Select is refused at open, and a
failing Select on one object raises (naming RustFS's leading-row schema
inference when the field is unbound) instead of filtering locally.
- MINIO_REGION is passed through when set.
- Tests: fakes for versioning off/unreadable, lifecycle missing/disabled/
tag-narrowed/whole-store, Select missing, tags unreadable, and the pass case;
the real-server contract uses OUSAST_MEMORY_TEST_BUCKET (else MINIO_BUCKET)
and never writes bucket configuration.
- ops/ax/README.md: RustFS support, the admin one-time setup, the agent policy.

plane/memory.py: the MemoryStore interface with FileStore (index.jsonl, facts by
content hash, repos/<host>__<owner>__<name>/<pin>.jsonl, idempotent ingest,
deterministic row ids, refusal below 1 GiB free naming the path) and MinioStore
(object metadata and tags, S3 Select pushdown probed once per process with a
logged local fallback, object version ids on every row read, versioning and
runs/ lifecycle helper, presigned URLs). OUSAST_MEMORY selects the backend;
MINIO_* settings come from .env; the minio SDK is the optional extra `minio`.
plane/tasks/remember.py: model-free rows (facts, verdict, unit_cost, alert)
from a case's artifacts; remember_run computes them on the host for a recorded
run without writing into it. reconciler.mark_done (477 lines total), seed
before and ingest after `ousast plane run`, `ousast plane remember <run>`.
The generator annotates each repo-facts Task with openultrasast.io/memory-key
(repo, pin, candidates digest, image digest) and the Run with its population
and split; plane/ regenerated.
