 Both checks pass. Let me verify the final files are
 correct.

 Both files are in place. Let me confirm the final state of
 the repository:


 $ cd /tmp/pi-goals-edxeth-trial-YxPEE5/repo && echo "===
 hello.ts ===" && cat hello.ts && echo "" && echo "===
 verify.log ===" && cat verify.log && echo "=== git status
 ===" && git status --short

 ... (11 earlier lines, ctrl+o to expand)
 bytes)
 byte-exact match: PASS
 === git status ===
 ?? hello.ts
 ?? verify.log

 Took 0.0s


 Done. Both tasks are complete in the disposable repo.

 The function (hello.ts)

 ```typescript
   export function greet(name: string): string {
     return `Hello, ${name}!`;
   }
 ```

 Byte-exact check result (verify.log)

 The check ran with the pre-installed Node v22.23.2 runtime
 (its native TypeScript type-stripping, no installs) and
 saved its output to verify.log:

 ```text
   input:       greet('World')
   output:      "Hello, World!"
   expected:    "Hello, World!"
   output bytes:
 [72,101,108,108,111,44,32,87,111,114,108,100,33] (13
 bytes)
   byte-exact match: PASS
 ```

 The output Hello, World! matches the expected string
 byte-for-byte (13 UTF-8 bytes: 72 101 108 108 111 44 32 87
 111 114 108 100 33), and the check exited with code 0
 (PASS). The temporary check script was removed, leaving
 only hello.ts and verify.log as untracked additions.

 I'll stay in this pane and wait — let me know if you'd
 like any changes.
