fix(coverage): preserve semantic wrapper provenance

[ifBars]

Closes #291.

Summary

• carry the matched S1API type and match strategy through coverage calculation so every covered type has provenance
• add analyzer-owned semantic mappings for runtime-agnostic temperature mirrors, and unwrap array element types during native-reference discovery
• make exact, normalized, nested, explicit, and fuzzy attribution deterministic and auditable in JSON/text reports
• add regression coverage for semantic mirrors, nested and normalized types, fuzzy matches, unrelated lookalikes, and deterministic owner selection

The source audit found that ScheduleOne.Casino.CasinoGameInteraction and ScheduleOne.Casino.CardController are not wrapped by the observational casino surface delivered by #281 (closing #239), so they intentionally remain uncovered. Casino controller and nested lifecycle types that are covered now receive concrete provenance instead of a blank coveredBy value.

Compatibility

• Public/protected API: no S1API runtime API changes; the analyzer JSON adds matchStrategy, and covered entries now always populate coveredBy
• Existing defaults and behavior: game/runtime behavior is unchanged; coverage matching keeps the existing strategies but now selects owners deterministically
• Stable IDs, saves, and network payloads: unchanged

Validation

Mono

• solution build: 0 warnings, 0 errors
• full suite: 716 passed, 0 failed, 0 skipped
• post-review analyzer regression suite: 4 passed

IL2CPP

• solution build: 0 warnings, 0 errors
• full suite: 702 passed, 0 failed, 0 skipped
• post-review analyzer regression suite: 4 passed

Runtime evidence

Not applicable: this changes the offline coverage tool and report schema only.

The analyzer was also run twice against the same local stable assemblies. Both reports were identical, increased covered types from 418 to 420, attributed both temperature examples, left the two unwrapped casino helper types uncovered, and had zero covered entries missing coveredBy or matchStrategy.

Documentation

• document the explicit/exact/normalized/nested/fuzzy matching order and provenance fields in the analyzer README
• member-level coverage remains out of scope and disabled

Summary by CodeRabbit

• New Features

  • Coverage reports now identify the matching S1API type and strategy used for each covered game type.
  • Added explicit and nested matching support for coverage relationships that cannot be inferred automatically.
  • Matching results are deterministic, with improved handling for wrapped and generic types.
  • JSON and text reports now include match-strategy details.

• Bug Fixes

  • Prevented fuzzy matching from incorrectly associating similarly named unrelated types.

• Documentation

  • Updated coverage documentation to describe all five matching strategies and enriched report output.

📝 Walkthrough

Walkthrough

The coverage analyzer adds explicit semantic mappings, five match strategies, deterministic API provenance, and match-strategy reporting. Assembly analysis unwraps element types. New tests cover mapping, matching, false positives, determinism, and JSON output.

Changes

Coverage provenance and matching

Layer / File(s)	Summary
Explicit mapping and type registration tools/S1APICoverageAnalyzer/Configuration/ExplicitCoverageConfig.cs, tools/S1APICoverageAnalyzer/Analysis/ApiAssemblyAnalyzer.cs	The analyzer registers and validates explicit temperature mappings. It exposes these mappings and unwraps arrays, pointers, and by-reference types during registration.
Deterministic coverage matching tools/S1APICoverageAnalyzer/Analysis/CoverageCalculator.cs, tools/S1APICoverageAnalyzer/Models/GameType.cs	Coverage matching now applies explicit, exact, normalized, nested, and fuzzy strategies. Each covered game type records its API type and match strategy. Candidate selection is deterministic.
Analysis wiring and report output tools/S1APICoverageAnalyzer/Program.cs, tools/S1APICoverageAnalyzer/Output/ReportGenerator.cs, tools/S1APICoverageAnalyzer/README.md	The program passes explicit mappings to the calculator. Text and JSON reports include match strategies. Documentation describes all five strategies.
Coverage regression validation S1API.Tests/Coverage/CoverageAnalyzerTests.cs, S1API.Tests/S1API.Tests.csproj, tools/S1APICoverageAnalyzer/S1APICoverageAnalyzer.csproj	Tests validate mapping, element unwrapping, match provenance, JSON fields, fuzzy-match rejection, and deterministic selection. Project access and references support the tests.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 51f6f

The analyzer README’s feature summary omits the newly supported Explicit and Nested strategies, leaving the documented capability list incomplete for maintainers. This is a minor documentation-only issue with no runtime impact, so the PR is merge-ready after normal checks; no actionable merge-blocking risk remains.

Full details: Linked Issues check

Explanation

The changes address issue #291 by adding semantic mappings, preserving API type and match-strategy provenance, supporting deterministic attribution, updating reports, and adding regression tests. The two audited casino types remain uncovered because the description states that they are not actually wrapped.
