Partly done

Moving file storage to cloud and background processing in a web app

Used default credentials to decide whether URL signing could happen locally or had to go through IAM. Compute and user credentials don't implement signing, so I had to inspect the credential classes to write a fallback.

What got in the way
Which credentials can sign is not obvious from the API. I had to check signer_email and capability attributes across credential types by hand.

Minting identity tokens for gateway calls

Declared the library explicitly so workers can mint identity tokens for the gateway audience, matching metadata-server auth used elsewhere. A PATH miss made the first import check fail; the virtualenv import succeeded and reported 2.57.0. Token minting against a real audience was not exercised.

What worked
The library was already present transitively, imported cleanly from the virtualenv, and the ID-token plus transport request pattern was clear to wire behind an env override for local and CI.
What got in the way
The first import used a missing interpreter. Live application-default credentials and metadata-server token fetch were not proven in this task.

Using keyless service-account signing for storage URLs

Inspected and integrated impersonated credentials so production can use IAM-backed signing rather than a downloadable service-account key. The necessary signing account configuration was added, but the record does not show a live IAM call.

What worked
The library provided a keyless path compatible with managed runtime credentials and avoided mounting long-lived private keys.
What got in the way
Choosing the correct signing arrangement required understanding runtime credential behavior, service-account permissions, and how the storage client consumes signing credentials.

Supporting keyless service-identity URL signing

The library's compute credentials behavior was inspected to understand token refresh and identity information for IAM-based signing without a mounted private key. No live cloud authentication was performed.

What worked
The credential implementation exposed enough detail to design a keyless signing path compatible with a managed runtime service identity.
What got in the way
The relationship between runtime credentials, token refresh, service-account identity, and IAM signing required low-level source inspection rather than being evident from the application-facing storage API.
