[aw-failures] Kiro/Cursor CLI auth fails intermittently — network allow-list gap + missing SECRET_ fallback

[github-actions]

Fix the Kiro allow-list before touching anything else — it's the confirmed cause

audit-diff between a failed and a passing Kiro run proves the firewall is denying two domains kiro-cli calls on every run; the auth harness also has no fallback for the AWF entrypoint's secret-renaming behavior. Both are one-sentence, low-risk config fixes.

Affected workflows / runs

• Smoke Kiro Execute Kiro CLI: 30975982770, 30974811087 (failed) vs 30977137021 (passed, but with the same domains denied)
• Smoke Cursor Execute Cursor Agent CLI: 30974539538, 30969707220 (failed) vs 30975573886 (passed)

Probable root cause

1. Stale network allow-list. shared/kiro.md's network.defaults lists codewhisperer.us-east-1.amazonaws.com, cognito-identity.us-east-1.amazonaws.com, prod.us-east-1.telemetry.kiro.aws.dev, prod.assets.shortbread.aws.dev, and wildcard *.kiro.dev. It's missing q.us-east-1.amazonaws.com and client-telemetry.us-east-1.amazonaws.com. audit-diff (base=30974811087, compare=30977137021) shows:

   {"domain":"q.us-east-1.amazonaws.com:443","status":"new","is_anomaly":true,"run2_blocked":42,"run2_status":"denied"}
   {"domain":"client-telemetry.us-east-1.amazonaws.com:443","status":"volume_changed","run1_blocked":2,"run2_blocked":36,"volume_change":"+1700%"}

   Even the passing run had 42+36 denied calls to these two domains — kiro-cli tolerates some of this, but it's plausible the auth-relevant call among them is what fails intermittently.
2. No secret-rename fallback. The AWF firewall entrypoint logs Unsetting sensitive tokens from parent shell environment... and renames KIRO_API_KEY→SECRET_KIRO_API_KEY, CURSOR_API_KEY→SECRET_CURSOR_API_KEY before the harness-script runs. Neither shared/kiro.md nor shared/cursor.md's harness-script reads the SECRET_-prefixed fallback name — both use process.env.KIRO_API_KEY / process.env.CURSOR_API_KEY directly (shared/kiro.md line ~138, shared/cursor.md equivalent). When the primary auth path fails (e.g. due to rejig docs #1), kiro-cli falls back to interactive device-flow login and fails with error: Failed to open URL; cursor-agent fails with Error: Authentication required... or set CURSOR_API_KEY environment variable.

Proposed remediation

1. Add q.us-east-1.amazonaws.com and client-telemetry.us-east-1.amazonaws.com to network.defaults in shared/kiro.md.
2. In shared/kiro.md's harness-script, change the model/auth read to fall back: process.env.KIRO_API_KEY || process.env.SECRET_KIRO_API_KEY. Apply the equivalent fallback for CURSOR_API_KEY/SECRET_CURSOR_API_KEY in shared/cursor.md.
3. Re-run gh aw compile to regenerate smoke-kiro.lock.yml / smoke-cursor.lock.yml.

Success criteria / verification

• 10 consecutive Smoke Kiro and Smoke Cursor runs with zero Execute {Kiro,Cursor} CLI failures.
• audit-diff against a fresh run shows zero denied entries for q.us-east-1.amazonaws.com and client-telemetry.us-east-1.amazonaws.com.
