Telecrawl is a Go CLI application that imports Telegram Desktop's `tdata` session data and creates encrypted, versioned backups. It reads the local Telegram Desktop data directory (platform-specific paths for macOS/Linux), parses the tdata format, and stores chat archives in a SQLite-backed store with merge/restore/tombstone semantics. The CLI exposes commands for import, backup, restore, search, and media reference handling. It runs as a Docker image with a non-root user, read-only tdata mount, and persistent /data volume. Architecturally, it is a monolith with a `cmd/telecrawl` entry point delegating to `internal/cli`, which orchestrates importers (`tdata`, `postbox`) and the `internal/store` persistence layer. The store handles schema migrations, snapshot merging, and search. Backup uses a Git remote pattern with safety guards against path overlaps. The codebase includes CI workflows, release automation, and security checks. Maintenance is active with frequent dependency bumps and CI. However, the store package is large and mixes concerns, and tdata/postbox importers are format-specific and may break if Telegram changes its data format. Hardcoded platform paths and schema backfill migrations are drift risks. Despite some data-audit scripts and fixture data, the dominant character is a CLI application.
