Description

pip install headroom-ai[bedrock] cannot serve users who authenticate with aws login (IAM Identity Provider / console-login, DPoP). Resolving those credentials requires the AWS Common Runtime (CRT); without awscrt, botocore raises MissingDependencyException.

The AWS docs state the requirement as: "Boto3 version 1.41.0 or later with AWS Common Runtime (CRT)" — i.e. both a modern boto3 floor and CRT (installed via the [crt] extra).

Type of Change

  • Bug fix (non-breaking)

Changes Made

  • pyproject.toml bedrock extra: bump boto3>=1.28.0 → boto3>=1.41.0, add botocore[crt]>=1.41.0 (installs awscrt).
  • uv.lock: regenerated — adds awscrt, resolves boto3 to 1.42.x.

No code changes — the bedrock backend already passes aws_profile_name through to the LiteLLM calls (via #1456); this just makes the installed dependencies actually able to resolve aws login credentials.

Impact

  • aws login (IAM Identity Provider / DPoP): now works — awscrt present.
  • aws sso login (classic Identity Center): unaffected (already worked).
  • static keys (~/.aws/credentials): unaffected.
  • Bumping the boto3 floor only affects the optional [bedrock] extra; bedrock users benefit from a current boto3 regardless.

Testing

Dependency-only change. uv lock resolves cleanly (257 packages, awscrt 0.29.2, boto3 1.42.38). No runtime code path altered, so existing bedrock tests are unaffected.

Checklist

  • Self-review performed
  • No new warnings
  • Linting passes

Additional Notes

Focused on the dependency gap only. ARN routing / named-profile wiring / docs are handled in #1456; pricing in #1485.

fix(bedrock): add boto3 1.41 + CRT for aws login credential resolution
7fa8fe2 
`aws login` (IAM Identity Provider / console-login, DPoP) requires boto3
1.41.0 or later WITH the AWS Common Runtime (CRT) per the AWS docs. Without
awscrt, botocore raises MissingDependencyException when resolving those
credentials, so `pip install headroom-ai[bedrock]` cannot serve users who
authenticate via `aws login`.

Bump the bedrock extra's boto3 floor to >=1.41.0 and add
botocore[crt]>=1.41.0 so awscrt installs automatically. Classic
`aws sso login` and static keys are unaffected.

The dependency change is narrowly scoped and matches the stated Bedrock credential-resolution failure mode: the bedrock extra now pulls a boto3 floor new enough for aws login credential support and includes the CRT extra so awscrt is installed with the optional backend. I do not see a correctness blocker in this patch.
