deployment/src-tauri/.gitignore listed /target, /gen and Cargo.lock together
with reasoning that fits the first two. /target is 2GB of compiled output and
/gen is emitted by tauri-build on every compile -- both genuinely
regenerated. A lockfile is not build output: it is the RESOLUTION RECORD, the
only artifact that makes cargo build reproducible.
Cargo's rule splits on crate type -- commit for a binary, ignore for a
library -- and cargo metadata reports this crate as kinds=['bin']
(src/main.rs, no lib.rs). Checked with cargo rather than inferred from the
file layout.
The stakes are concrete: Cargo.toml pins nothing tighter than
tauri = { version = "2" }, while the lockfile pins 430 packages. Without it
an inheritor building next month resolves a different dependency tree than
the one that produced the shipped 64 MB binary, and method 5 is already
"built, not shot", so its build must at least be repeatable.
Verified before committing 109KB: cargo metadata --locked --offline succeeds,
so the lockfile is consistent with the manifest, and it contains zero local
paths or credentials.
check:tauri gains a fifth assertion -- Cargo.lock present AND TRACKED.
Tracked-ness is the point: the file sat on disk the whole time and was still
absent from every clone. Negative-tested against the real state, not a
simulation: the gate FAILED naming the file while it was untracked, and
passed once staged.
