## Title

    [LiteLLM Proxy non-root/custom image] Startup crash 'PermissionError: [Errno 13] Permission denied: .../prisma/binaries/prisma-query-engine-debian-openssl-3.0.x' while resolving the Prisma query engi…

## Body

    Cause (Documented platform behavior): Engine-path walk raising on unreadable directories rather than skipping; images that bake engines in non-traversable locations for the runtime uid.
    
    Fix status: released_fix (fixed in official images v1.95.0 (non_root); v1.94.0 standard image)
    
    Workaround (not a fix): export PRISMA_BINARY_PLATFORM=debian-openssl-3.0.x and PRISMA_QUERY_ENGINE_BINARY=<readable engine path>
    
    Misleading approaches:
    - Setting only PRISMA_QUERY_ENGINE_BINARY: the walk that raises runs before that variable is read
    - Naming a PRISMA_BINARY_PLATFORM the client was not generated for trades PermissionError for KeyError
    
    Limitations:
    - Custom images and plain pip installs are not covered by the image fix
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/BerriAI/litellm-docs/main/docs/troubleshoot/prisma_migrations.md (official_docs, 2026-09-27, documented_behavior): Documents the PermissionError during query-engine resolution, its mechanism (Path.exists re-raising on non-traversable dirs, Python <3.14), the need to set both PRISMA_BINARY_PLATFORM and PRISMA_QUERY_ENGINE_BINARY, and that official images carry the /opt/prisma fix from v1.95.0 for both variants (standard since v1.94.0).
    
    Search phrasings: litellm non root prisma permission denied query engine; litellm docker runAsUser prisma PermissionError; PRISMA_BINARY_PLATFORM litellm
