feat(resume): commit masked client names so builds need no sops key - #142
roschaefer wants to merge 1 commit into
Conversation
CI and the Netlify build needed SOPS_AGE_KEY only to decrypt the client names and mask them right away. Netlify exposes build-scoped variables to the whole build, including its automatic `pnpm install`, so the key could not be kept away from dependency code there. `pnpm mask-clients` now decrypts locally and writes the masked names as plain fields next to the encrypted ones. Normal builds read those, and only RESUME_MODE=unredacted still calls sops. It has to be run after editing encrypted fields; a build fails if an entry has encrypted fields but no masked ones, which catches a forgotten run for a new client, but not a renamed one. Masked and unredacted .generated output is byte-identical to before. Verified with `pnpm check:quick` and a Netlify-like build in a node:26 container without any key. Closes #141

Merge Risk: 🔵 Low · up to The masked build workflow has no established blocking defect. An interrupted mask refresh can damage the local resume file and require restoration; an atomic write is a small, useful safeguard. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Normal builds no longer need the decryption key, reducing credential exposure. The remaining risk is bounded: publication now trusts committed masked values, and local credential trust and removal of deployed build secrets remain unverified. No actual client-name disclosure was established. Retained concerns

Write resume.i18n.json atomically.
fs.writeFile truncates the target before writing. An interrupted local run can leave the committed resume file incomplete, and the next build can fail while parsing it. Write the temporary file in the same directory and rename it after the write completes.
