…icks#6193) ## Changes Sets `GOFIPS140=v1.0.0` in `Taskfile.yml`, so every `task` invocation builds the CLI against the FIPS 140-3 validated Go Cryptographic Module. Adds a test that reads the built binary's build info to confirm it really was built with it. ## Why Releases are moving to FIPS builds (databricks#6262). Go picks its cryptographic module at build time, so testing without it exercises a configuration we no longer ship. In the Taskfile rather than a workflow env because every consumer goes through `task` — local `./task test`, CI's `task test`, and the integration suite, which runs `task integration` from eng-dev-ecosystem. One line covers all three, with no cross-repo change. Bare `go test` outside `task` is not covered, so the check fails there rather than silently passing. Worth flagging: this makes eng-dev-ecosystem integration runs FIPS without a change in that repo. ## Tests Full unit + acceptance suite under FIPS, locally and in CI (all six cells, macOS and Windows included) — no failures. Integration against real workspaces under FIPS: ~11,000 tests across six cells (three clouds x linux/windows), and the FIPS check passed in every cell. The four unrelated failures were a leftover-state 409 on AWS and three cluster timing flakes; baseline nightlies show the same rate without FIPS. Perf: CLI startup 12ms -> 13ms, RSA-4096 key generation 653ms -> 1.35s. The new build tag invalidates the Go build cache once, so the first build after this merges is a full rebuild.

| Released binaries are now built against the FIPS 140-3 validated Go Cryptographic Module, with FIPS 140-3 mode enabled by default. TLS connections negotiate only FIPS-approved cipher suites, which drops ChaCha20 and CBC from what the client offers. FIPS mode can be disabled at startup with `GODEBUG=fips140=off`, which restores the previous TLS behaviour ([#6262](https://github.com/databricks/cli/pull/6262)). | |||

Is this really notable? We could move it to the CLI section.

@ilyakuz-db I triggered a rerun (and investigation) of the most recent failure. Looks like a flake. |

Changes
Build released binaries with
GOFIPS140=v1.0.0. This links the FIPS 140-3 validated Go Cryptographic Module into the binary and defaults FIPS 140-3 mode on, so no runtime flag is needed.Why
Regulated environments (FedRAMP, IL5) require cryptography to come from a validated module. This has to be set at build time: the runtime
GODEBUG=fips140=ononly toggles the mode on whatever module was already linked, so without the build variable, there is no validated module in the binary and no certificate to cite.Pinned to a frozen version rather than an alias.
v1.0.0is the version covered by CMVP certificate#5247This changes behavior for everyone, not just regulated users: the TLS client offers only FIPS-approved suites (6 instead of 13, dropping ChaCha20 and CBC)
CI coverage for the FIPS build is added separately in #6193
Tests
Ran the whole unit and acceptance suite against a FIPS build — no failures. Also confirmed all six release targets (linux/darwin/windows x amd64/arm64) cross-compile with the variable set; none of the platforms Go excludes from FIPS mode are in our matrix.
