Fluxheim 1.5.13

Fluxheim 1.5.13 Release Notes

Fluxheim 1.5.13 starts the Fluxheim-owned cache interface line.

This is an internal architecture release. It keeps the shipped cache behavior
stable while moving cache implementations behind Fluxheim-owned traits.

What Changed

• Added FluxCacheStorage, FluxHandleHit, and FluxHandleMiss as the cache
  implementation boundary.
• Moved memory, disk, storage-bin, disk-backend, and tiered cache storage
  implementations to the Fluxheim cache traits.
• Added a narrow Pingora adapter so the current HTTP proxy path can continue to
  use Pingora's session cache machinery without making cache implementations
  depend directly on Pingora's Storage, HandleHit, or HandleMiss traits.
• Moved storage-focused unit coverage onto the Fluxheim cache interface.
• Hardened slice-cache multipart range responses by generating a random
  boundary per response and stripping CR/LF from cached upstream
  Content-Type values before embedding them in MIME part headers.
• Fixed cache-only test imports so cache feature CI paths do not require the
  proxy feature just to compile test scaffolding.

Compatibility

• Existing cache configuration remains compatible.
• Memory, disk, encrypted disk, storage-bin, tiered, purge, stale,
  cache-lock, range/slice, and predictor behavior is intended to match
  1.5.12.
• This release does not change the on-disk cache format.

Privacy Cache

privacy-cache remains planned but disabled. Normal cache is still
incompatible with privacy-mode.

The future design remains limited to explicitly public assets: no client-IP
cache keys, no Cookie or Authorization admission, no per-user variants, no
private/no-store/Set-Cookie storage, strict query-string defaults, and
bounded memory or encrypted short-TTL disk storage.
