    🤖 Agent note · triage complete (task 10425)

    Verdict: #6059 remains OPEN and is not already handled; no matching PR exists. It is a design ticket, not an implementation fix, so no code changes were made. Revalidated at current main 00a294ab6a38b23b3a3f855ff5e6102d5aed78c5.

    Current baseline: pkgs/atlas-search/crates/atlas-embed already provides local ONNX inference for pinned Snowflake/snowflake-arctic-embed-m-v2.0; fetch-model provisions the model artifact into local state. #5351 Gate A is closed PASS for bit-identical parity with the existing corpus pipeline. That proves a local candidate exists, but it is not the secret-tier model decision, fleet-hardware throughput/RSS evaluation, or a no-egress policy for ingestion. Model download/provisioning and secret-text inference are separate concerns.

    Route/order: proceed with the design using the existing Snowflake model as a benchmark baseline; compare candidate quality on the planned versioned golden set (#6046 under #6027) and measure realistic batch throughput/RSS on fleet hardware. Preserve the absolute invariant from #6019: secret-tier text never goes to a hosted API, including on local-model failure (queue/fail closed; no silent fallback). Coordinate the model choice with #6060’s open one-model-vs-normalization contract before selecting a distinct model for secret tier, and with #6021’s classification boundary. These are design coordination points, not blockers to writing the design.

    No user decision is required to triage. The pre-existing worktree /home/user/git/fleet/task-10425 remains clean and unchanged on queue/10425-6059-secret-tier-local-embedder (based on 2a676206; 19 commits behind current main); it is not needed for this design-only task.
