Use a stable snapshot or cursor when possible, and add a high-water mark plus ID deduplication when an API exposes only limit and offset.

Give each frontend a distinct public client identity, authorize the user and tenant independently, and record all three in audit events.

Route every tool call through one validated, authenticated, tenant-aware dispatch boundary and return sanitized security errors.

Use one Serilog ExpressionTemplate with conditional blocks so error details appear only when needed and each event is written once.

Return one public login failure, keep status and timing comparable, and move account details into protected logs and recovery flows.

Use the Bitbucket username in the HTTPS remote, enter a scoped API token as the password, and keep the token out of the remote URL.

Centralize SaaS sign-in with OpenID Connect, validate tokens at each service boundary, and separate authentication from current authorization decisions.

Diagnose an Apache HTTPS request that reaches the wrong virtual host by checking address and port matching, ServerName, DNS, SNI, and loaded configuration.

Make long-running POST operations safe to retry with a client-generated idempotency key, an atomic operation record, and a status endpoint.

Set PostgreSQL tenant context locally inside the same transaction and pooled connection that runs tenant queries, then always release the client safely.
