One Shared Deploy Credential Is Forty Pipelines' Worth of Blast Radius

Set up once, when there was one service. Forty pipelines later, every one of them still uses it, and it can deploy to production, which means it can read the secrets and infrastructure of everything it touches.

Account Linking by Email Match Trusts a Claim, Not a Verification

Continue with Google links to the matching existing account by email address. That is correct when the identity provider genuinely verified the email. Some providers make verification optional, and not every system checks which claim it is reading.

Authorization Belongs in the Tool, Not in the Prompt
