Problem

Deployment run 39211267548 published an active agent version but failed the Responses smoke check. Foundry reported a transient no_capacity failure, and the SDK's retry completed after the caller's 120-second deadline had canceled the request. The Invocations smoke check was consequently skipped.

Changes

• Increase both Responses and Invocations CLI deadlines from 120 to 300 seconds, with six-minute step limits for setup and validation headroom.
• Preserve the 40-minute job bound, exact-reply/terminal-state validation, pinned version and fresh sessions, approval/CI gates, secret handling, and failure behavior. Do not add workflow-level retries, rollback, or model/configuration changes.
• Add executable Responses coverage for success, malformed/incomplete/canceled streams, wrong replies, duplicate completion, error events, and nonzero CLI exits; update both protocol timeout assertions.
• Document the new bounds and their limits: additional retry headroom does not guarantee model capacity.

Validation

• py -m unittest discover -s tests -p test_deploy_foundry_workflow.py — 34 tests passed using Python 3.12, Git Bash, and jq 1.8.1 locally.
• actionlint -shellcheck= -pyflakes= .github/workflows/deploy-foundry.yml — passed with actionlint 1.7.12.
• git diff --check — passed.

All invocations in the regression tests are local stubs. No live invocation, deployment, rollback, quota, or Azure configuration change was performed. Python 3.13/Linux execution remains covered by PR CI; live verification requires a separately authorized operation.
