* feat(gallery): verify backend OCI images with keyless cosign
Close a trust gap where a registry compromise or MITM could silently
replace a backend image: the gallery YAML tells LocalAI which image to
pull, but until now nothing verified the bytes came from our CI.
Consumer (pkg/oci/cosignverify):
- New package using sigstore-go to verify keyless-cosign signatures.
- OCI 1.1 referrers API + new bundle format (no legacy :tag.sig).
- Policy fields: Issuer / IssuerRegex / Identity / IdentityRegex /
NotBefore. NotBefore is the revocation lever — keyless Fulcio certs
are ephemeral so revocation is policy-side; advancing not_before in
the gallery YAML invalidates every signature predating the cutoff.
- TUF trusted root cached process-wide so N backends from one gallery
do 1 fetch, not N.
Plumbing:
- pkg/downloader: ImageVerifier interface + WithImageVerifier option
threaded through DownloadFileWithContext. Verification runs between
oci.GetImage and oci.ExtractOCIImage, with digest pinning via
pinnedImageRef to close the TOCTOU window. Skips the verifier's HEAD
when the ref is already digest-pinned.
- core/config: Gallery.Verification YAML block.
- core/gallery: backendDownloadOptions builds the verifier from the
policy; applied on initial URI, mirrors, and tag fallbacks.
- core/gallery/upgrade: the upgrade path now routes through the same
options builder. A regression Ginkgo spec pins this contract —
without it, UpgradeBackend silently bypassed verification.
- core/cli: --require-backend-integrity (LOCALAI_REQUIRE_BACKEND_INTEGRITY)
escalates missing policy / empty SHA256 from warn to hard-fail.
Producer (.github/workflows/backend_merge.yml):
- id-token: write at job scope (PR-fork-safe via existing event gate).
- sigstore/cosign-installer@v3 pinned to v2.4.1.
- After each docker buildx imagetools create, resolve the manifest
list digest and run cosign sign --recursive --new-bundle-format
--registry-referrers-mode=oci-1-1 against repo@digest. --recursive
signs the index and every per-arch entry, matching how the consumer
resolves a tag to a platform-specific manifest before verifying.
Rollout: backend/index.yaml has no `verification:` block yet, so this
PR is backward-compatible — installs proceed with a warning until the
gallery is populated. Strict mode is opt-in.

* refactor(gallery): plumb RequireBackendIntegrity through config instead of env
The previous implementation re-exported the --require-backend-integrity
CLI flag into LOCALAI_REQUIRE_BACKEND_INTEGRITY via os.Setenv, then
re-read it in core/gallery via os.Getenv. This leaked process state
into the gallery package and made the flag impossible to override
per-call or test without touching the env.
Add RequireBackendIntegrity to ApplicationConfig (with a matching
WithRequireBackendIntegrity AppOption) and thread the bool through
every install/upgrade path: InstallBackend, InstallBackendFromGallery,
UpgradeBackend, InstallModelFromGallery, InstallExternalBackend,
ApplyGalleryFromString/File, startup.InstallModels. Worker subcommands
gain the same env-bound flag on WorkerFlags so distributed-worker
installs honor it consistently with the worker daemon path.
Add a forbidigo lint rule against os.Getenv / os.LookupEnv / os.Environ
to keep the env-leak pattern from creeping back. Existing offenders
(p2p, config loaders, etc.) are baseline-grandfathered by the existing
new-from-merge-base: origin/master setting; targeted path exclusions
cover the legitimate cases — kong CLI entry points, backend
subprocesses, system capability probes, gRPC AUTH_TOKEN inheritance,
test gating env vars.

This changeset introduces LRU management of loaded backends. Users can

setting LocalAI in single active backend mode we set LRU to 1 for

- Add a system backend path
- Refactor and consolidate system information in system state
- Use system state in all the components to figure out the system paths
to used whenever needed
- Refactor BackendConfig -> ModelConfig. This was otherway misleading as
now we do have a backend configuration which is not the model config.
