In `@plugins/_temporary-scaled-evals/deploy/k8s/README.md`:
- Line 23: Move the agent-sandbox controller and Sandbox CRD prerequisites above
the bring-up command list in the README, ensuring readers see them before the
./eval-smoke.sh command and other setup instructions.
In `@plugins/_temporary-scaled-evals/deploy/k8s/registry-auth.yaml`:
- Line 41: Update the registry secret synchronization endpoint configured in the
deployment manifest to use authenticated encryption, replacing the plain HTTP
pod-to-Service URL with the supported HTTPS endpoint or enforcing mTLS for this
hop. Ensure the corresponding Service and API configuration used by the registry
refresh flow supports the selected secure transport.
In `@plugins/_temporary-scaled-evals/deploy/k8s/settings.env`:
- Line 64: Update the NMP_JOBS_EXECUTORS Kubernetes job configuration to use a
dedicated, lower-privilege Platform Jobs service account instead of
scaled-evals-control-plane for outer task-build and evaluation Pods. Ensure the
referenced service account has only the permissions required to create Jobs,
read Secrets, and exec into Pods, while preserving the existing child-sandbox
token-mount behavior.
In `@plugins/_temporary-scaled-evals/src/nemo_scaled_evals_plugin/controller.py`:
- Around line 159-163: Replace the timestamp-only projection watermark with a
composite (updated_at, id) keyset cursor. Update list_changed_since to apply a
strict tuple comparison when a cursor id is present, while preserving the
initial-query behavior, and advance the cursor from each successfully projected
row so batches sharing a timestamp continue to the next row.
In `@plugins/_temporary-scaled-evals/src/nemo_scaled_evals_plugin/projection.py`:
- Line 204: Update EvaluationProjectionReader.list so Entity Store uses a stored
composite sort key containing row_created_at and evaluation_id, and pass that
single composite field to SyncEntityClient.list for both sorting and cursor
filtering. Ensure pagination cursors use the same composite key so tied
timestamps cannot cause evaluations to be skipped.
- Line 120: Update EvaluationProjectionWriter.watermark() to recover and return
the composite cursor containing both row_updated_at and the last projection id,
then pass both cursor values to list_changed_since during restart recovery.
Preserve the existing ordering and batching behavior while ensuring tied
timestamps resume after the recovered id.
In
`@plugins/_temporary-scaled-evals/src/nemo_scaled_evals_plugin/tasks/evaluation_execution.py`:
- Line 43: Update the kubeconfig server URL construction near the "server" entry
to wrap IPv6 hosts containing colons in brackets before appending the port,
while leaving IPv4 and hostname formatting unchanged. Add a test covering a
compressed IPv6 KUBERNETES_SERVICE_HOST value and verify the generated
KUBECONFIG URL is valid.
In
`@plugins/_temporary-scaled-evals/src/scaled_evals/api/build/task_image_identity.py`:
- Line 424: Validate the decoded auth document in the task image identity flow
before any .get access, and validate the auths value before iterating with
.items(). Reject non-mapping document and auths values by raising
TaskImageIdentityError, while preserving the existing behavior for valid
mappings.

Adds a derived read model for evaluations in Entity Store, with Postgres still authoritative. Entity Store offers per-entity optimistic locking but no atomic dequeue and no multi-entity transaction, so the six queue-like tables cannot move yet; a single-writer projection is the shape that is safe on that store today. The entity promotes only the columns the list endpoint filters or sorts on and parks the rest in a JSON `detail` blob, so the existing response schemas rebuild unchanged. Three SQL predicates are materialized as fields because the store cannot express them reliably: `standalone` for `benchmark_run_id IS NULL`, `deleted` for `deleted_at IS NULL` (kept projected so reads answer 404 without falling back to Postgres), and a lowercased `search_blob` so `$like` matches case-insensitively regardless of collation. The row's own timestamps are carried separately because `EntityBase.created_at` records when we last wrote, which would break cursor ordering. The writer recovers its watermark from the projection itself, so no new Postgres column is added now and deleted later, and a restarted controller resumes instead of replaying the table. Upserts copy fresh fields onto the stored entity so the write stays a compare-and-swap. The reader mirrors the repository list/get signatures and emulates keyset pagination: the store sorts one field, so the (created_at, id) tiebreaker is reapplied locally and the cursor becomes an $or row comparison. Projection and reads are separate flags, both off by default. The router picks a source through one helper with a deferred plugin import, so scaled-evals still runs standalone and Postgres stays the default. Signed-off-by: Arpit Singh (SW-CLOUD) <arpsingh@nvidia.com>
Self-review of the projection turned up three things worth correcting before the flags are ever turned on. The detail blob copied every selected column, including `instruction_prefix`, `instruction_postfix` and `initial_user_turns`. Those are user prompt content and no evaluation response returns them, so copying them widened where that content lives to serve no read. The set is now derived from the response model, which also drops `backend_handle` (the detail builder strips it), the evidence/archive columns and the joined image refs, and keeps following the schema as fields are added. `parity_report` compared a row against `entity_to_row(row_to_entity(row))` — the same expression on both sides, so it could not report a difference. It now takes a real read-back, and the round-trip test drives it through the writer and reader so the check has something to fail on. That test also goes through the router's own response builder rather than the bare model. Two comments overclaimed. Local re-sorting orders a page but does not decide which rows the store selected, so equal `created_at` values at a page boundary can still repeat or skip. And the LIKE pattern is escaped for SQL's `ESCAPE '\'`, which `$like` does not honour, so a query containing % or _ under-matches. Both ceilings are now named where the code makes the tradeoff.

Summary
Stacked on #1887. Adds a read-only projection of scaled-evals evaluations into Entity Store so Platform services can query them, while Postgres stays the source of truth. Both the projection writer and the Entity Store read path are behind flags that default off, so merging this changes nothing at runtime.
The constraint that shapes the design: scaled-evals has six queue-like tables (dispatch claims, build claims, runtime-resource cleanup, execution cleanup, Switchyard campaigns, service heartbeats) and every one depends on
SELECT ... FOR UPDATE SKIP LOCKEDplus multi-row transactions. Entity Store offers per-entity optimistic locking, no atomic dequeue, and no cross-entity transaction. Those tables therefore cannot move yet. A single-writer derived read model is the shape that is safe on that store today, and it is the only thing this PR builds.Changes
entities.py—ScaledEvaluation, a projection of oneevaluationsrow. Fields promoted to the top level are exactly those the list endpoint filters, searches or sorts on; the rest ride in a JSONdetailblob so existing response schemas rebuild unchanged.projection.py—EvaluationProjectionWriter(upsert, watermark recovery),EvaluationProjectionReader(list/get mirroring the repository signatures), andparity_report.controller.py— aproject_evaluationsreconcile phase, registered only when the projection flag is on.evaluation_repository.py—list_changed_since, the change feed the projection consumes.routers/evaluations.py— one_evaluation_reads(db)helper selecting the source. Everything else in the router is untouched.settings.py— four flags, all defaulting to off/safe.Where the reviewer should look
projection.py, the reader. This is the hardest part and where a subtle bug would hide. Three impedance mismatches are handled explicitly and are worth checking:standaloneforbenchmark_run_id IS NULL,deletedfordeleted_at IS NULL(soft-deleted rows stay projected so reads answer 404 without falling back to Postgres), and a lowercasedsearch_blobso$likeis case-insensitive regardless of collation.$orrow comparison and the(created_at, id)tiebreaker is reapplied locally.row_created_at/row_updated_at, becauseEntityBase.created_atrecords when we last wrote and would break cursor ordering.entities.py,PROJECTED_COLUMNS. Derived from the response model rather than hand-listed, so it follows schema changes. This deliberately excludesinstruction_prefix,instruction_postfixandinitial_user_turns— user prompt content that no response returns. See the security note below.The upsert in
EvaluationProjectionWriter.project. It copies fresh fields onto the stored entity, not the new one, becauseidanddb_versionare read-only views over private attrs and carrying them across is what makes the write a compare-and-swap. A racing write loses the swap and retries next pass.Known ceilings, named in code

Correct, but heavier over the wire than the SQL path. Worth revisiting if list latency matters before cutover.Security note for review
The projection copies evaluation metadata into a second datastore with its own API surface. Read-path tenancy is preserved (
owner_idis filtered the same way SQL filters it), but anyone able to listscaled_evals_evaluationentities directly through the Entity Store API is outside scaled-evals' own authorization.PROJECTED_COLUMNSis narrowed to exactly what the responses read specifically to bound this — no prompt content, no credentials payloads (only credential ids, as in the API today). Worth a second opinion on whether that bound is tight enough before either flag is enabled in a shared environment.Type of Change
