First code in the repo. Workspace root is Application/ per readme;
members are src/core (crate rpn-core) and src/cli (binary rpnc).
Crate names are prefixed to avoid clashing with the std `core`
crate; directory names follow the readme layout.
Dependencies (versions pinned in Cargo.lock):
- core: sqlx (mysql, runtime-tokio, chrono, rust_decimal), chrono,
csv, thiserror, serde/serde_json, tracing, plus sha2 (SHA-256
file checksums required by schema.sql), rust_decimal (exact
DECIMAL(10,2) money, forced by the "money is DECIMAL
everywhere" decision), tokio and tempfile as dev deps.
- cli: clap (derive), tokio, tracing-subscriber (env-filter),
anyhow, serde/serde_json, chrono, csv.
The extra crates beyond the readme stack (sha2, rust_decimal,
tracing-subscriber, tempfile-dev) are direct consequences of
already-committed decisions; flag for maintainer review.
No feature logic yet: rpnc is an empty shell, the domain modules
land in the TDD slices that follow.
- [web]: port and public fqdn for the daemon (Caddy proxies from a
separate jail); port defaults to 8080
- [state]: daemon pidfile and logs directory, default ~/.config/rpn
- [backup]: timestamped dumps for rpnc db backup, default
~/.config/rpn/backups; rpnc db restore looks here by default
- cli.md: document the optional positional path and the directory
defaults for db backup/restore
