-# Rust Software Quality Rules
-
-
-## DOC_76 (The 76-Rule for Documentation Comments)
-
-- Documentation comments (`///`, `//!`) on **public** constructs must be at
-  most **76 characters** per line, including leading indentation;
-- Wrap text **greedily** (pack to maximum width) — do not wrap early if the
-  next word fits on the current line;
-- Code blocks inside doc comments (triple backticks) are exempt;
-- List items in doc comments should end with a semicolon;
-- Inline comments (`//`) inside functions are limited to **100 characters**
-  per line, wrapped greedily;
-- Private/non-`pub` constructs are exempt from DOC_76 for their doc
-  comments;
-
-Run `./scripts/check_doc_76.py` to verify compliance.
-
-
-## DERIVE_LAYOUT (Derive Layout & Formatting)
-
-Multi-trait `#[derive(...)]` macros must be split into separate,
-single-trait lines, ordered alphabetically by trait name. Tightly coupled
-traits may remain on one line: `#[derive(Eq, PartialEq)]`,
-`#[derive(Ord, PartialOrd)]`.
-
-`rustfmt.toml` sets `merge_derives = false` to preserve this layout.
-
-Run `./scripts/check_derives.py` to verify compliance.
-
-
-## RUST_TEST_NAMING
-
-All test methods must use `SHOUTING_SNAKE_CASE` - e.g. `TEST_PARSING()` -
-except where a word in the snake case represents a specific construct (such
-as a struct, enum, type, function, macro, or field name), in which case that
-word must preserve its exact correct case - e.g.
-`TEST_AutoBuffer_WITH_INTERNAL_SIZE()`, `TEST_doom_scope_1()`,
-`TEST_type_name_only_WITH_SomeCustomType()`.
-
-Run `./scripts/check_test_names.py` to verify compliance.

+### Minimum Supported Rust Version (MSRV)
+
+The declared Minimum Supported Rust Version (MSRV) for **Diagnosticism.Rust** is **1.74**.
+
+This MSRV guarantee applies to the library crate itself, its runtime dependencies (`[dependencies]`), and its build dependencies (`[build-dependencies]`). Downstream consumers compiling this crate as a dependency are guaranteed that it builds cleanly on the declared MSRV toolchain.
+
+Development dependencies (`[dev-dependencies]`, such as benchmarking frameworks like **criterion**) may require newer Rust toolchains for local development or performance testing. These dev-dependencies are never fetched or compiled by downstream consumers and do not affect the library's MSRV guarantee.

 Verify RUST_TEST_NAMING: test functions and test modules use TEST_ prefix

 (type, function, macro, field, etc.) which must preserve exact case.

+PascalCase construct), it may be delimited with an extra underscore on
