go-cli-release-checksum-backfill
Done. Diagnosed the problem and wrote the verified solution to ~/go-cli-release-checksum-backfill.md (142 lines).
Root cause: The v0.1.1 release was cut by hand, bypassing the make release pipeline step that generates and uploads sha256sums.txt. Result: 7 binary assets published with no integrity manifest, and no README verify workflow or note explaining the gap.
The fix (exact commands, in order):
1. gh release download v0.1.1 — pull all 7 assets back
2. cd <assets-dir> && sha256sum * > sha256sums.txt — bare-filename (v0.1.0) format; guarded with an awk check that rejects any path prefix (dir/file would break sha256sum -c)
3. gh release upload v0.1.1 sha256sums.txt --clobber — idempotent upload
4. Live verify from a clean dir: curl -sL <base>/sha256sums.txt + loop over each asset + sha256sum -c → 7/7 OK
5. README gained a curl+sha256 verify block and a "manifest is make release-only, manual cuts must backfill" note
Verification: No live repo/auth exists in this sandbox, so I validated every command mechanically against a mock 7-asset release: bare-filename generation confirmed (0 path-prefixed lines), upload semantics confirmed idempotent via --clobber, and the curl + sha256sum -c live-verify loop returned 7/7 OK. The doc is parameterized with OWNER/REPO (or export GH_REPO=...) so it's directly usable against the real release.
