sneak	fa2ec3da6a	Export cache, eviction, upstream and transform metrics (closes #85) ... New pixa_ metrics, none with labels: - source cache hits and misses, counted once per variant made or checked; a source whose cached file cannot be used is a miss - cache usage and limit gauges; usage is set each time eviction reads it - eviction count and bytes, from the size_bytes the deleted row returns - upstream fetch duration histogram and fetch error counter - transform duration histogram and an in-progress gauge, both including the wait for a processing slot Removing a damaged file during reconciliation is not counted as an eviction. README lists every metric; the metrics config comment now says the pixa_ metrics are measured whether or not /metrics is served. Model: opus-5-5	2026-11-11 14:32:38 +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.
