clawbot	8feed69143	Check cached sources with upstream after the cache TTL (closes #69, closes #83) ... A cached source and its variants were served until eviction, so a changed image at the same URL was never picked up. Once a source was last checked 24 hours ago, the next request for one of its images asks upstream with If-None-Match and If-Modified-Since, from the ETag and Last-Modified it stored. A 304 renews the source and its variant without a download or a conversion. New bytes replace the source, and each variant made before them is converted again. A failed check serves the cached image and puts the URL in the negative cache. Sources and variants not checked successfully for 30 days are evicted. A variant file's modification time is its source's check time, so a hit still makes no database call. Existing tests change only in call signatures. The test that asserted two-day-old entries are served without asking upstream is replaced by the new ones. Model: opus-5-5	2026-11-11 00:24:06 +00:00
clawbot	b73bbde46e	Detect a fetched image's format from its bytes once (closes #319) ... magic.DetectFormat returns an imagerequest.Format. ValidateMagicBytes returns the format it checked against the upstream Content-Type. The cache reads a cached source's format from its file's first bytes, as it reads a variant's. The proxy hands the format to Process. Process refuses a format that is not a source format, and input libvips would load with another loader, such as an SVG passing as AVIF. Format.MIMEType declares each MIME string once, and the fetcher, the cache's variant read and the Accept matching use it. magic.MIMEType, magic.ImageFormat, MIMEToImageFormat, magic's SVG detection, detectFormat, formatFromString, FormatToMIME and Result.InputFormat are gone.

clawbot	17376d885b	Split internal/imgcache into the image proxy and the cache (closes #317) ... The new package internal/imageproxy holds Proxy, which was imgcache.Service, with its Config, ImageResponse, CacheStatus and errors. imageproxy.New makes and registers the counters of upstream fetches and transforms. internal/imgcache holds the cache only, with its hit and miss counters, and imgcache.CacheConfig is imgcache.Config. The cache reads and writes each kind it keeps with one pair of methods: Variant and PutVariant, Source and PutSource, Failure and PutFailure. Source replaces LookupSource followed by GetSourceContent. imgcache.go and module.go are gone. The proxy's tests moved with it. The cache's tests check that the reconciliation pass removes an empty or cut file and its row. The proxy's tests remove them by hand, then check that Get fetches or converts again.
