sneak	c3a6799763	Count hits, misses, fetches and transforms as Prometheus counters (closes #311) ... The five counts the cache_stats table held are now Prometheus counters in memory, in internal/imgcache/counters.go, on the default registry that /metrics serves. The Increment methods add to them, so counting makes no database call. cache_stats, Cache.Stats, Service.Stats, CacheStats and the pending counts are gone, with their tests. The background goroutine now writes only access times, and its names say so: StartPendingAccessTimeWrites, StopPendingAccessTimeWrites and pendingaccesstimes.go. The counters count for the whole process, so the tests that check how much they rose do not call t.Parallel. Two stop tests whose write under way was a hit count now use an access time.

clawbot	6b19e4c96c	Declare only the tables and columns pixa writes and reads (closes #310) ... Removes output_content and request_cache, which nothing writes, and every column that was written but never read: the host, path, query, content_type and fetched_at of source_content, the content_type and created_at of variant_content, and the status_code, error_message and fetched_at of negative_cache. StoreSource no longer takes the fetch result and LookupSource returns only the source key. StoreVariant no longer takes a content type and StoreNegative no longer takes a status code or message, so extractStatusCode and the status constants, which only fed status_code, are gone. Reconciliation adopts a variant file without opening it, as its row no longer records a content type. Tests that set or checked a removed column follow. Model: opus-5-5	2026-10-26 09:29:26 +01:00
clawbot	5f9d624d74	Serve a cache hit with no database read or write (closes #309) ... A hit opens the variant file and nothing else: its content type comes from the file's first bytes, and a file in no output format is a miss. Its access time and count, and the access time of a cached source a miss uses, go without waiting to one background goroutine that writes them once a second; each kind of access time waits in a channel of 10,000 that drops the rest. Expired negative cache rows are left to CleanExpired. The .meta files, metaCache, Lookup and golang-lru go, with their tests; the two reconciliation walks, identical without the .meta skip, share one. make bench runs a parallel cache hit benchmark on the host, outside make check.
