 - Format: any human-readable string that uniquely identifies the build — a semver tag, a git commit SHA, or a combination (e.g. `1.4.2`, `1.4.2-abc1234`, `abc1234`).
 - The version text must be legible but visually subordinate — use a muted color and small font size so it does not compete with page content.

-## Recommended implementation
-
-**Frontend (JS/TS build tools)**
-
-Expose the version through an environment variable at build time and reference it in the footer component:

-```
-

 ## What is NOT allowed
 
 - Omitting the version from any page, including error pages.

 where the vendor publishes a checksum alongside the binary.
 Applies to: NVIDIA drivers, vendor CLI tools, firmware packages.
 
----

-## Download Order
-
-Always download the checksum file **before** the installer:
-
-```sh
-BASE_URL="https://vendor.example.com/downloads/${VERSION}"
-BIN_FILE="/var/cache/vendor-${VERSION}.run"
-SHA_FILE="/var/cache/vendor-${VERSION}.run.sha256sum"

-else
-    echo "verified from cache"
-fi
-```
-
-**Never check only for file existence.** Check that the file is non-empty (`-s`) AND passes checksum.
-
----
-
-## Version Validation
-
-Before writing build scripts, verify the version URL actually exists:
-
-```sh
-curl -sIL "https://vendor.example.com/downloads/${VERSION}/installer.run" \
-    | grep -i 'http/\|content-length'
-```
-
-A `404` or `content-length: 0` means the version does not exist on that CDN.
-Vendor version numbering may have gaps (e.g. NVIDIA skips minor versions on some CDNs).
-
----
+See `README.md` for shell snippets.
 
 ## Rules
 
-- Download checksum before installer — never after.
+- Download the checksum file **before** the installer — never after. If the download is
+  interrupted, you still have the expected checksum to verify against on retry.
 - Verify checksum before extracting or executing.
 - On mismatch: delete the file, exit with error. Never proceed with a bad installer.
+- Never assume a cached file is valid — a previous download may have been interrupted.
+  **Never check only for file existence**: the file must be non-empty (`-s`) AND pass checksum.
 - Cache by `version` + any secondary key (e.g. kernel version for compiled modules).
+- Before writing build scripts, verify the version URL actually exists (`curl -sIL`).
+  A `404` or `content-length: 0` means the version is absent on that CDN; vendor version
+  numbering may have gaps.
 - Never commit installer files to git — always download at build time.
 - Log the expected hash when downloading so failures are diagnosable.
