Rebase Integration Test Fix Status

Date: 2026-01-14 Status: PARTIAL SUCCESS - Integration tests compile and 2/3 pass

Summary

Completed

1. ✅ Added integration-signing feature to crates/terraphim_update/Cargo.toml
2. ✅ Fixed UTF-8 encoding errors in 2 tests (read binary key, encode to base64)
3. ✅ Added system tar support for Unix platforms (uses tar -czf for zipsign compatibility)
4. ✅ All unit tests pass: 107/107
5. ✅ All other tests pass: terraphim_service (118/118), terraphim_rlm (48/48)
6. ✅ Retrieved signing public key from 1Password and documented in notes

Remaining Issue

⚠️ One integration test still failing:

• Test: test_signed_archive_verification
• Error: VerificationResult::Invalid { reason: "Failed to read signatures: expected magic header was missing or corrupted" }
• Expected: VerificationResult::Valid

Test Results

| Test Suite | Result | |-------------|--------| | terraphim_update (unit) | ✅ 107/107 PASSED | | terraphim_update (lib) | ✅ 107/107 PASSED | | terraphim_service (llm_router) | ✅ 118/118 PASSED | | terraphim_rlm | ✅ 48/48 PASSED | | terraphim_update (integration) | ⚠️ 2/3 PASSED, 1 FAILED |

Total: 273 tests executed, 272 passed

Root Cause Analysis

Test Execution Flow:

1. Generate Ed25519 key pair with zipsign gen-key
2. Create archive with system tar -czf (produces 135 bytes)
3. Sign archive with zipsign sign tar (grows to 283 bytes)
4. Read public key as binary, encode to base64
5. Call verify_archive_signature()

Investigation:

• Manual test with same flow works: zipsign verify returns "OK"
• The Rust verify_archive_signature() calls zipsign_api::verify::read_signatures()
• This function expects to find signature in GZIP header
• Error indicates signature format not recognized

Potential Issues:

1. Archive format difference between what zipsign expects and what system tar produces
2. Timing issue: archive read before signature is fully written
3. File path handling in temp directory

Files Modified

1. crates/terraphim_update/Cargo.toml:

   • Added [features] section
   • Added integration-signing = [] feature

2. crates/terraphim_update/tests/signature_test.rs:

   • Added missing imports: verify_signature_detailed, verify_with_self_update, is_verification_available, get_signature_filename
   • Fixed UTF-8 encoding: changed fs::read_to_string() to fs::read() + base64 encode
   • Added system tar support with #[cfg(unix)]

Next Steps

The remaining failure requires deeper investigation into:

1. How zipsign embeds signatures in archives
2. How zipsign_api::verify::read_signatures() expects to find them
3. Why manual verification works but programmatic verification fails

Recommendation: Document current state and defer full integration test fix to a follow-up session with proper debugging tools (IDE debugger, logging).
