bug: BuildQualityFromMappings hardcodes AssertionDetectionConfidence to 0 for external analyzers

[gxmiranda]

Problem

BuildQualityFromMappings in internal/adapter/quality.go hardcodes AssertionDetectionConfidence: 0 for all external analyzer quality reports (line 138):

AssertionDetectionConfidence: 0, // External analyzers don't provide aggregate detection confidence

This causes gaze quality --analyzer output to always show:

Assertion detection confidence: 0%

even when the external analyzer (e.g., snake-eyes) is correctly detecting and classifying assertions across all test functions.

Evidence

Running gaze quality --analyzer snake-eyes --language python . against the snake-eyes repo:

• 326 tests analyzed
• Assertions ARE detected — equality, error_check, generic assertion types are present in every mapping row
• Per-test AssertionCount is correctly populated (e.g., len(testMappings))
• But AssertionDetectionConfidence is always 0%

Root Cause

The Go-native quality pipeline computes detection confidence internally because it has access to the full assertion detection pipeline. The external analyzer path added in PR unbound-force#242 has no mechanism to receive or compute this metric — it was deferred with a comment.

Proposed Fix

Two options:

1. Gaze-side computation (no protocol change): compute detection confidence from the data already available. For each test function, if the external analyzer returned at least one mapping row, that test has detected assertions. The metric becomes len(tests_with_assertions) / len(all_tests) * 100. This requires knowing the total test count, which could come from the discover method or be inferred from unique test_function values in the mapping data.

2. Protocol extension: add an optional assertion_detection_confidence (int, 0-100) field to the test_mapping response. The external analyzer computes this itself since it knows which tests it scanned but found no assertions in (true negatives vs detection failures). This is more accurate but requires a protocol version bump.

Option 1 is simpler and can ship without protocol changes. Option 2 is more accurate for analyzers that want to report detection quality.

Impact

MEDIUM — the metric is misleading (shows 0% when detection is working correctly), but does not affect contract coverage scores, gap identification, or over-specification counts. Cosmetic/informational only.

[gxmiranda]

Ready for implementation. Two fix approaches are proposed:

Option 1 (Recommended): Compute detection confidence from existing data without protocol changes. Calculate as len(tests_with_assertions) / len(all_tests) * 100.

Option 2: Extend protocol with optional assertion_detection_confidence field, allowing analyzers to report their own metric.

Option 1 is simpler and ships immediately. The proposed test case should verify that BuildQualityFromMappings produces non-zero confidence values when test mappings contain assertion data.

This issue appears to reference code that doesn't exist in the repository. The file internal/adapter/quality.go and the function BuildQualityFromMappings mentioned in the issue body are not present in either this fork or the upstream repository (unbound-force/gaze).

Additionally, the issue is already closed, and the most recent comment appears to be unrelated to this project (it mentions TestLandingPage.js and Mozilla addons, which have no connection to this Go test quality analysis tool).

If you encountered a real issue with external analyzer integration, please verify the file paths and function names, and open a new issue with accurate references to the existing codebase.
