Doppler is the source of truth for secrets; GitHub / Cloudflare / Firebase are runtime mirrors

Decision

Doppler is the single source of truth for every secret used across the chirag127/oriz family. Every other place a secret can live — GitHub Secrets, Cloudflare Worker vars + secrets, Firebase functions config, and local .env files via doppler run — is a downstream mirror populated by Doppler’s sync integrations. Humans only ever write secrets at Doppler.

The user’s home-grown envpact vault stays around for personal / non-family secrets but is no longer the family-stack source of truth.

Why

User asked the agent to choose between GitHub Secrets, Doppler, and Infisical (1Password’s automation product was a fourth candidate). The agent picked Doppler for these concrete reasons:

• Free 5 users is permanent on the free tier. The family uses 1; the 4-user buffer covers any future contributor without ever needing to upgrade.
• Best integration coverage of the modern free options — covers GitHub Actions + Cloudflare + Firebase out of the box, which is exactly the family’s runtime triangle. Infisical is newer with rougher edges; 1Password’s automation is a local-signing-model, not a sync-out model.
• Built-in rotation for supported integrations — turns the rotate-leaked-secret runbook into “click rotate in Doppler, integrations re-sync within seconds”.
• Audit log — every read / write / sync is timestamped + attributed; satisfies the family’s secrets-handling policy.
• Best DX — doppler run -- pnpm dev is the simplest possible local-dev story, and beats every alternative we tried.

Implications

Architecture

        Doppler (source of truth)
           +-- ? GitHub Secrets   (org / repo / env scope)
           +-- ? Cloudflare       (Worker vars + secrets)
           +-- ? Firebase config  (functions:config + Auth provider creds)
           +-- ? Local dev        (via `doppler run -- pnpm dev`)

• All secrets originate at Doppler. Humans never gh secret set or wrangler secret put by hand for production secrets — Doppler does it automatically.
• Bootstrap secret: DOPPLER_SERVICE_TOKEN itself is the one credential that has to be planted into each runtime by hand (it’s the credential that does the syncing). It’s also the only secret whose rotation requires a tiny manual touch.
• Local dev: doppler run injects secrets at process start. No .env file is ever committed (per no-hardcoded-secrets.md).
• envpact stays for the user’s personal secrets (cross-machine creds outside the family stack). It is not deprecated — its scope just narrows.

Project layout in Doppler

Operational

• Rotation runbook (rotate-leaked-secret.md) gains a Doppler step: revoke at provider ? reissue ? write at Doppler (NOT at GH / CF / Firebase) ? wait for sync (seconds) ? run sanity check. Direct writes to runtime mirrors are forbidden because they’re overwritten on the next sync.
• Audit reviews quarterly — read Doppler’s audit log for unexpected read events; cross-check against expected workflow runs.
• Access — only the user’s identity has Doppler access today. Adding a contributor uses one of the 4 free seats.
• Backup — Doppler exports JSON / dotenv on demand; quarterly export committed (encrypted, age-recipient under user’s key) to a private repo as cold-storage fallback.

What we don’t do

• No secret pasted into chat, ever — this is the no-hardcoded-secrets rule, unchanged.
• No .env files committed to git, ever — doppler run is the only way local dev sees secrets.
• No production secrets written by hand to GH / CF / Firebase UIs — only Doppler writes them.
• No two source-of-truth stores — envpact and Doppler do not race. Family-stack secrets are Doppler-only.

Cross-refs

• Doppler service entry
• GitHub Secrets — runtime mirror
• envpact — narrowed to personal use
• No hardcoded secrets rule
• Secrets handling policy
• Rotate leaked secret runbook
• Multi-provider auth decision — provider creds land in oriz-firebase Doppler project
• Cron split decision — both substrates pull from Doppler
