fix: update Identity Match response example — missing serve_window_sec field

[AndyBevan]

Happy to fix this - I was taking a look at the repo, cloned and ran the tests and 1 fails, I don't see another PR fixing this. Below is what Claude generated for me.

Summary

Test suite fails with schema validation error: TMP Identity Match response example is missing the required serve_window_sec field introduced in #4070.

Error

❌ TMP Identity Match response — web (overview walkthrough): root: must have required property 'serve_window_sec'

Root Cause

Commit 91f417f8a ("spec(tmp): IdentityMatch frequency-cap data flow + serve_window_sec #4070) merged 2026-05-07 updated the schema in static/schemas/source/tmp/identity-match-response.json to:

• Add serve_window_sec (required field, 1-300 seconds)
• Remove ttl_sec (deprecated)

However, the test example in tests/example-validation-simple.test.cjs (line 584) was not updated and still references the old ttl_sec field.

Fix Required

File: tests/example-validation-simple.test.cjs
Line: 584

Change from:

await validateExample(
  {
    "type": "identity_match_response",
    "request_id": "id-7c9e1d",
    "eligible_package_ids": ["pkg-outdoor-audio"],
    "ttl_sec": 60
  },
  '/schemas/tmp/identity-match-response.json',
  'TMP Identity Match response — web (overview walkthrough)'
);

Change to:

await validateExample(
  {
    "type": "identity_match_response",
    "request_id": "id-7c9e1d",
    "eligible_package_ids": ["pkg-outdoor-audio"],
    "serve_window_sec": 60
  },
  '/schemas/tmp/identity-match-response.json',
  'TMP Identity Match response — web (overview walkthrough)'
);

Impact

• Full test suite (npm test) fails and exits early
• Blocks all downstream tests: extensions, migrations, unit tests, type checking
• Test coverage: example validation tests 35/36 passing

Related Issues

• Introduced by: spec(tmp): IdentityMatch frequency-cap data flow + serve_window_sec #4070
• Schema change: static/schemas/source/tmp/identity-match-response.json
• Doc updates: docs/trusted-match/specification.mdx, docs/trusted-match/buyer-guide.mdx, etc.

Verification Steps

1. Update tests/example-validation-simple.test.cjs line 584
2. Run npm run test:examples — should show 36/36 passing
3. Run npm test — should complete full suite without errors
