Uneventful: digest-only bump of FerrLabs/.github reusable workflows (2ea7662 → 15286b3), same job/input shape across all five callers. All 19 checks green.

Follow-up: PR was rebased to a newer digest since my last approval (2ea7662 → 15286b3), now 2ea7662 → fba6f4b. Re-checked what's new in that range for FerrLabs/.github:

• #327 (docker RUN descriptor limit) — already covered by the prior approval.
• #330 (github actions bump) — only touches reusable-ci-rust.yml, reusable-release-rust.yml, reusable-ferrflow-release.yml (dtolnay/rust-toolchain digest bump, gated behind hashFiles('**/Cargo.toml') != ''), renovate.yml, workflow-templates/ci-rust.yml. This repo is Go-only, no Cargo.toml, so that step never runs here.
• #334 (concurrency group disambiguation) — touches reusable-ci-node.yml and reusable-sonarqube-scan.yml. This repo's reusable-ci-go.yml call pins its internal sonar call to a separate fixed digest (2883414f...), unrelated to this bump, so no effect.

Nothing in the new range touches reusable-ci-go.yml, reusable-pr-title.yml, reusable-renovate-dispatch.yml, or reusable-security-scan.yml beyond the pin itself. All 19 checks green. Still uneventful.
