Append-only WAL with CRC32-validated records, automatic segment rotation at 128 MiB, background periodic fsync, and crash recovery by truncation at the first corrupt or incomplete record. Record format: type(1) | len(4) | payload | crc32c(4). Two payload types: series (ref + labels) and samples (batch of ref/t/v). Fixed-width encoding througout. Torn-write harness truncates at every byte offset and asserts recovery produces a valid prefix of the original sequnce, both single-segment and multi-segment. DESIGN.md, NOTICE.md, and README.md.

- internal/chunkenc: Gorilla XOR chunk encoding follows the Prometheus tsdb/chunkenc implementation.
- internal/wal: Write-ahead log design is informed by the Prometheus tsdb/wal package. Uses a simpler record format without page-level framing; shares the same well-established WAL patterns (segmented append-only files, CRC32C validation, recovery by truncation).
