Decision guide
Do less first.
Start with one reversible secret and one action. Expand only after audit, revocation, and human approval feel boring. This table matches the leak you have today to the first Asiri move.
Copied .env filesUse env export or file mounting on one development envelope.
Agents seeing raw keysUse environment injection or broker access through an authenticated identity on a trusted device. Labels are audit-only.
Production SSH/API accessSet the envelope to strict so administrators see the access before the value is released.
CI sprawlEnroll the runner as a device and keep expiry short.
Server replacementRevoke old device trust and rotate upstream credentials after suspected exposure.
