Conversation
Clippy has been a hard gate on CI for a while, but only because the workflow appends `-D warnings`. A plain `cargo clippy` locally reported the same findings as warnings and exited 0, so the gate was invisible until push time. Moving the levels into the manifest makes the local command behave like the CI one without anyone having to remember a flag. `unsafe_code = "forbid"`, not `deny`: there is no `unsafe` anywhere in this workspace and no reason for any to appear in game logic, persistence or simulation. `forbid` additionally rejects a local `#[allow(unsafe_code)]`, which is the whole point — `deny` can be switched off in the file that wants to break the rule. `clippy::all` carries `priority = -1` so the group sets a floor while a single lint can still be configured individually at the default priority. Without it cargo rejects the combination as ambiguous the moment a specific lint is added. Scope, recorded in the manifest so it does not get overstated later: this buys *clippy* parity with CI, not *warning* parity. CI's `-D warnings` also denies ordinary rustc warnings. The obvious fix — `warnings = "deny"` under `[workspace.lints.rust]` — is deliberately not taken, because workspace lints apply to every cargo invocation and it would turn an unused variable into a hard error during `cargo build` and `cargo test` while you are mid-edit. Being stricter than CI in that spot is a worse trade than the residual gap. All seven manifests opt in, including the root `[package]` that shares a file with the `[workspace]` table — omitting that one would leave the whole command layer unlinted. Cost to green is zero, measured rather than assumed: `cargo clippy --workspace --all-targets` and the `--features mcp` pass both exit 0 with no warnings on the pinned 1.95.0 toolchain. Verified the lints bite with no `-D warnings` on the command line: an `unsafe` block fails, its `#[allow(unsafe_code)]` is itself rejected (E0453), and a `v.len() == 0` fails with `-D clippy::len-zero implied by -D clippy::all`.

Pull request overview
This PR centralizes Rust/Clippy lint levels in src-tauri/Cargo.toml under [workspace.lints], and opts all workspace members into those lint settings so local cargo clippy matches the CI gate behavior (without needing -- -D warnings).
Changes:
- Add
[workspace.lints.rust](unsafe_code = "forbid") and[workspace.lints.clippy](clippy::allatdeny, withpriority = -1) to the Tauri workspace manifest. - Opt the root package and each workspace member crate into workspace lints via
[lints] workspace = true.

to clarify that it matches CI’s Clippy lint levels, not full CI coverage: CI
additionally uses --workspace --all-targets and performs a second pass with the

The comment claimed a plain `cargo clippy` reproduces what CI enforces. It does not: CI lints `--workspace --all-targets` and then makes a second pass with `--features mcp`, while a bare `cargo clippy` sees one package, its default targets and its default features. A change can be clippy-clean locally and red on CI without either the levels or this file being at fault. The scope note already walked back the rustc-warning half of the claim and left the coverage half standing, which is the more likely one to mislead — nobody reaches for `warnings = "deny"` by accident, but plenty of people run `cargo clippy` from `src-tauri/` and believe it.

What and why
Clippy has been a hard gate on CI for a while, but only because the workflow appends
-D warnings.A plain
cargo clippylocally reported the same findings as warnings and exited 0 — so the gatewas invisible until push time. Moving the levels into the manifest makes the local command behave
like the CI one without anyone having to remember a flag.
forbid, notdeny, forunsafe_code. There is nounsafeanywhere in this workspace — thefive grep hits are the word inside a test name and in comments about zip-slip — and no reason for
any to appear in game logic, persistence or simulation.
forbidadditionally rejects a local#[allow(unsafe_code)], which is the entire point:denycan be switched off in the exact filethat wants to break the rule. If a genuine need ever arrives, deleting the line is the conversation.
priority = -1on the clippy group so it sets a floor while a single lint can still beconfigured individually at the default priority. Without it, cargo rejects the combination as
ambiguous the first time someone adds a specific lint.
All seven manifests opt in, including the root
[package]that shares a file with the[workspace]table. Omitting that one would leave the whole Tauri command layer unlinted, and it isthe easy one to miss.
Scope — stated here and in the manifest so it does not get overstated later
It also buys CI's lint levels, not CI's coverage. CI lints
--workspace --all-targetsandthen makes a second pass with
--features mcp; a barecargo clippysees one package, its defaulttargets and its default features, so it can be clean while CI is red. Match the scope as well as the
levels before calling a change clippy-clean.
This buys clippy parity with CI, not warning parity. CI's trailing
-D warningsalso deniesordinary rustc warnings. The obvious-looking fix —
warnings = "deny"under[workspace.lints.rust]— is deliberately not taken: workspace lints apply to every cargo invocation, so it would turn
an unused variable into a hard error during
cargo buildandcargo testwhile you are stillmid-edit. Being stricter than CI in that spot is a worse trade than the residual gap.
Nothing speculative is included.
pedanticandnurseryare not adopted, because their cost wasnot measured — and because CI already runs
-D warnings, a lint added here at"warn"becomes ahard gate the moment it lands. There is no advisory tier, so anything added must be measured first.
No linked issue — infrastructure change.
How to verify
Cost to green is zero, measured rather than assumed. On the pinned toolchain, both of these exit
0 with no warnings:
Note the absence of
-- -D warnings: that is the change.The lints were confirmed to bite, again with no

Suggested merge order: this one first, ahead of the three test PRs alongside it. It is what makes
clippy a real gate, and those PRs add roughly 400 lines of test code that no branch has linted under
it. The combination has been tested — clippy exit 0, 457 tests green — but merging this first keeps
every intermediate commit on
