feat(infra): deploys create Maple's AWS integration identity - #1646
Conversation
Each prd instance and PR preview declares an IAM user that can only sts:AssumeRole into MapleIntegration-* roles, plus its access key, and binds both into api and alerting. Dev keeps the shared dev user from .env.local.

Maple review🟢 Confidence 8/10 · likely safe to merge Every deploy but dev now declares its own AWS integration IAM user plus access key and binds them into api and alerting, replacing the shared env identity. Contained and in the existing alchemy idiom; safe to merge once the prd identity cutover is checked.

Maple looks once, an hour after the first deploy that carries the merge. |
Stacked on #1635.
Deploys now create Maple's own AWS identity for the AWS integration, instead of someone creating an IAM user by hand and copying its key into the secret store.
packages/infra/src/aws/integration-principal.tsdeclares an IAM user (maple-integrations,-eu,-pr-<n>) whose only permission issts:AssumeRoleonarn:aws:iam::*:role/MapleIntegration-*, and an access key for it.MapleStackContext.awsPrincipal), the same way api'sVCS_SYNC_HOP_SECRETis bound today. Nobody handles the key.deploys.awsIntegrationPrincipal: on for prd, prd-eu and every PR preview (preview:webincluded, so AWS connections can be tested there), off for dev, which keeps the shared dev user from.env.local.AWS_ROLE_NAME_PREFIXin@maple/domain/aws, shared by the connection names and this policy.Each instance trusts its own user, so a customer stack set up on a preview only works with that preview, and US and EU stay separate.
