-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Build & Run
-
-```bash
-go build -o saya-today-thumbnail-generator
-./saya-today-thumbnail-generator -c config/config-local-unix.sample.json
-```
-
-No Makefile. No test files exist yet — `go test ./...` would be the convention.
-
-## What This Is
-
-Concurrent batch thumbnail generator. Reads images from a source (Backblaze B2, S3/S3-compatible, or local filesystem), converts to WebP/JPEG with configurable quality/size, writes to output storage. Maintains a CSV-based file cache to skip already-processed images.
-
-## Architecture
-
-Three pluggable abstractions, each using a factory/registry pattern keyed by string type:
-
-- **InputClient** (`internal/client/input/`) — scans source files, provides readers. Implementations: `b2`, `s3`, `local-unix`
-- **OutputClient** (`internal/client/output/`) — writes converted files. Implementations: `b2`, `s3`, `local-unix`
-- **Converter** (`internal/converter/`) — decodes image, resizes (Catmull-Rom), encodes to target format. Implementations: `webp`, `jpeg`
-
-Each has a `New*Map` factory function returning a map of type-string → constructor.
-
-## Config System (`config/config.go`)
-
-JSON config with discriminated unions — `"Type"` field selects which struct to unmarshal into. Supports `${ENV_VAR}` expansion in string values. Validated with go-playground/validator.
-
-Key config knobs: `MaxProcessThreads` (conversion concurrency), `MaxPreProcessThreads` (I/O concurrency), `RewriteOn` strategy per converter (`Never`/`UnequalHashInCache`/`Always`).
-
-Sample configs in `config/config-*.sample.json`. Actual configs are gitignored.
-
-## Concurrency Model
-
-Two-tier semaphore system in `main.go`: pre-process (file scanning/reading) and process (image conversion) run with separate thread pool limits. Graceful shutdown on SIGTERM/SIGINT via early-termination flag. Cache map protected by `sync.RWMutex`.
-
-## Environment
-
-Uses direnv (`.envrc`) for credentials (`B2_KEY_ID`, `B2_APPLICATION_KEY`, `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`). S3 client supports custom endpoints and path-style addressing for S3-compatible stores (MinIO, etc.).
