fix: pass required IAM keys to Lightsail API

[BeforeLights]

Summary

• pass the invitation digest and worker capability signing keys into the Lightsail API container
• document both required 32-byte base64url host secrets in the protected environment example
• add a release regression test so pilot composition cannot omit either runtime key again

Production incident

The main release reached Lightsail but the API rejected the incomplete pilot environment with LOCAL_IAM_KEY_INVALID. Existing secrets were preserved; the two newly required keys were generated directly on the protected host without logging their values.

Verification

• red test reproduced both missing variables
• focused Lightsail deployment tests: 5/5 passed
• Docker Compose config validation passed
• static infrastructure checks passed
• secret-pattern scan passed
• Prettier and git diff --check passed

Summary by CodeRabbit

• Configuration

  • Added required security key settings for invitation verification and worker capability signing.
  • Updated the deployment configuration and environment template to support these settings.

• Tests

  • Added deployment checks to verify the new security settings are configured correctly.

📝 Walkthrough

Walkthrough

The Lightsail environment template adds two signing key variables. The API Compose service requires both variables and validates one at startup. Deployment tests verify the Compose allowlist and placeholder formats.

Changes

Lightsail signing key configuration

Layer / File(s)	Summary
Configure and validate signing keys infrastructure/lightsail/.env.example, infrastructure/lightsail/compose.pilot.yml, tools/repo-cli/test/lightsail-deployment.test.mjs	The environment template defines the invitation digest and IAE worker capability signing keys. The API service requires both keys. Tests verify the required variables and their placeholder format.

Estimated code review effort: 2 (Simple) | ~5 minutes

Merge Risk: 🔵 Low · up to 483e4

The protected environment example uses a placeholder shorter than the required 43-character secret, which could prevent API startup if copied unchanged. The PR is otherwise mergeable, but the example and its validation should be corrected before or immediately after merge.

Greptile Summary

This PR fixes the Lightsail pilot API environment by requiring and forwarding two runtime signing keys.

• Documents the invitation digest and worker capability signing secrets in the protected environment example.
• Adds both variables to the API service with required Compose interpolation.
• Extends Lightsail deployment regression coverage to prevent either variable from being omitted.

Confidence Score: 5/5

The PR appears safe to merge, with the required Lightsail API keys consistently documented, forwarded, and regression-tested.

The added variable names match the runtime consumers, required Compose interpolation prevents incomplete pilot deployments, and no actionable defect remains in the changed paths.

Important Files Changed

Filename	Overview
infrastructure/lightsail/.env.example	Documents both newly required 32-byte base64url host secrets consistently with the existing protected-secret placeholders.
infrastructure/lightsail/compose.pilot.yml	Requires and forwards both keys to the pilot API service using fail-fast Compose interpolation.
tools/repo-cli/test/lightsail-deployment.test.mjs	Adds regression assertions covering the API environment entries and corresponding environment-example placeholders.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the documented secret placeholder length.

CHANGE_ME_43_CHAR_BASE64URL_KEY contains 31 characters, although its name claims 43. A 32-byte unpadded base64url secret requires 43 characters. If an operator copies this example without replacing every value, API startup validation can reject it. Use a 43-character placeholder and update tools/repo-cli/test/lightsail-deployment.test.mjs Lines 79-83 to validate the required length and character set.
