## Investigating module checksum mismatches
During tool installation or dependency preparation, a checksum mismatch means
the bytes Go read differ from a recorded checksum. The message alone does not
identify whether those bytes came from the local cache or a remote source.
Keep checksum verification enabled and retain the error, selected version,
and relevant `go.sum` entries. Go's [module authentication reference](https://go.dev/ref/mod#authenticating)
describes these checks.
To isolate a public ReleaseKit download from application settings and the
existing module cache, run the following with a compatible local Go toolchain.
Replace `v0.2.0` with the affected version. This diagnostic accesses the public
Go proxy and checksum database and retains its temporary directory for inspection.
```sh
(
checksum_dir=$(mktemp -d) || exit 1
printf 'Checksum investigation directory: %s\n' "$checksum_dir"
cd "$checksum_dir" || exit 1
GOENV=off GOFLAGS= GOWORK=off GOTOOLCHAIN=local \
GOPRIVATE= GONOPROXY= GONOSUMDB= \
GOPROXY=https://proxy.golang.org GOSUMDB=sum.golang.org \
GOMODCACHE="$checksum_dir/modules" \
go mod download -json gitea.maximumdirect.net/eric/ReleaseKit@v0.2.0
)
```
A successful isolated download establishes that this version verifies through
the selected proxy. Compare its `GoMod`, `GoModSum`, and `Sum` with the affected
cache and the application's recorded checksums. Locate the original cache with
`go env GOMODCACHE`; Go stores downloaded module metadata separately from the
extracted source. See the [module cache reference](https://go.dev/ref/mod#module-cache).
Once a stale cache entry is confirmed, preserve a copy, quarantine that entry
while no Go process is using it, and retry normal dependency preparation. For
a confirmed stale `.mod`, quarantine that file alone. Preserve application
checksums and published tags. Routine downloads can continue to use the normal
module cache.
If the isolated download also fails, investigate the selected proxy, tagged
source, and recorded checksums with the maintainer before changing local state.
Record any difference between proxy and direct fetching. A confirmed cache
problem can be repaired locally; changes to published source follow the
maintainer's immutable-release procedure.

## Testing synthetic modules
Tests that serve synthetic module versions through local proxies should pass a
test-owned temporary `GOMODCACHE` to every Go subprocess that consumes those
versions. Scope fixture-specific proxy and checksum settings to those processes.
This applies the [testing policy's isolation requirements](policy/testing.md#test-execution-requirements)
to module downloads and keeps fixture metadata out of developer and CI caches.
Distinct fixture version numbers still occupy the real module's cache namespace.
Use temporary caches even when the selected versions have never been published.
Verify isolation at the shared fixture boundary; ordinary builds can continue
to use their prepared dependency cache. Consumer recovery guidance lives in the
[module checksum investigation guide](consumers/delivery.md#investigating-module-checksum-mismatches).
