    Ouros X 2.1.23

    The Mac preview has been withdrawn and is no longer available for download. This build is local-only and is not available from the public stable download or automatic update channel. These notes remain as a record of its changes.

    • Semantic and keyword retrieval use a mapped, quantized index with bounded caches, while preserving declared tags, current source revisions, cancellation and source-byte citations.
    • Broad keyword matches retain the correctly ordered result page without materializing every matching object in SQLite. Active content queries use an appropriate foreground scheduling scope and restore the caller's prior scheduling policy afterward.
    • Search reports when a requested folder becomes unavailable, keeps results from healthy folders, and recovers when the same folder returns. Intentional scope removal clears the warning.
    • Saved-index opening overlaps bounded checksum and descriptor validation without removing corruption checks. Native file-event callbacks have an owned executor with joined teardown.
    • Nearly parallel embedding vectors retain correct top results. Queries inside a write transaction cannot publish uncommitted cache entries that survive a rollback.

    Verification scope​

    This is a local build, not a public download or stable-channel release. Existing authentication, paid admission, model selection, permissions, updater trust and appearance remain unchanged.

    The retained controlled workload contains one million real files and current production-ingested vectors, but uses repeated synthetic distractors around an enriched public SciFact subset; it is not one million unique semantic texts. Warm-filesystem latency observations are not first-query, every-run, whole-application memory or physical-device guarantees. Cold startup, a retained initial parent replay miss, native sanitizer/tool boundaries and installed-workflow acceptance are recorded separately in the engineering evidence. Stable-channel promotion requires its normal separate acceptance.

    Platform availability​

    The withdrawn Mac build was checked natively on Apple Silicon and under Rosetta for Intel code, not on a physical Intel Mac. Those checks do not establish full feature acceptance or current download availability. The public Mac installation guide covers the unchanged Apple Silicon stable release.

    The Linux preview is a separate native client with its own package version, requirements and verification limits. It is not this Mac release.
