Christian Heim	b0570bdf9d	Mirroring a tag now checks it with a HEAD first and reuses the cached manifest when the digest is unchanged, falls back to the cached tag when the upstream body is cut off, and keeps a tag that a client pull moved while the walk ran. The platform filter is checked across the whole image, so a nested index without the wanted platform no longer fails it, and a 304 for a per-Accept fallback entry only refreshes that client's own keys instead of overwriting the shared entry.	2026-10-13 17:02:32 +02:00
Christian Heim	5b9a5fca6b	When the shared tag entry holds a representation the client does not accept, the lookup now goes on to the client's own per-Accept entry instead of giving up, so a Docker-only client still gets its cached manifest list after an OCI index was cached for the same tag.	2026-10-12 10:29:12 +02:00
Christian Heim	055540a540	Manifests are now cached under a key that ignores the client's Accept header: a digest names one document, and a tag is shared by all clients that accept an index type, so Docker, containerd and Podman read the same entry and a pre-fetched image is found offline. Clients without index support keep their per-Accept entry, and the old keys are still written and read as fallback.	2026-10-11 23:59:29 +02:00
