The C2 invariant — that an instruction file can be emitted as markdown and re-ingested without losing components, instructions, or option trees — is the technical foundation for this claim. + +Today, the three strongest roundtrip test suites (`DocumentationRoundTripTests`, `MarkdownImportTests`, `MarkdownFileTests`) are excluded from compilation in `src/ModSync.Tests/ModSync.Tests.csproj:88-95`. The product documentation claims guides are "round-trippable" but no test enforces this in normal or agent runs. The 186-vs-189 component divergence between markdown-derived and TOML instruction files (documented in `src/ModSync.Tests/MarkdownTomlParityTests.cs:72-90`) is a known exception, but without active roundtrip tests, there's no way to distinguish "known exception" from "regression." + +This gap blocks the strategy's multi-author share/publish track: a share link or `modsync://` handoff is worthless if the shared instruction file is lossy. + +--- + +## Actors + +- A1.

The `DocumentationRoundTripTests`, `MarkdownImportTests`, and `MarkdownFileTests` suites are re-included in the default test compilation (remove the `Condition` that excludes them from `ModSync.Tests.csproj`). +- R2. All re-enabled tests pass in the default test configuration. Tests that cannot pass due to known corpus divergences (e.g., the three KOTOR1 romance components) are marked with explicit skip reasons referencing the documented exception list, not blanket exclusions. + +**C2 invariant regression guard** + +- R3. A regression test enforces the C2 invariant: given any instruction file in the test corpus, emitting it to markdown and re-ingesting produces identical components, instructions, and Choose trees. The test runs in the default agent flow (not a scheduled or excluded set). +- R4. The C2 test uses the pinned `mod-builds` corpus (or a committed subset) so results are reproducible across agents and CI. When the corpus is absent, the test skips cleanly rather than hard-failing. + +**Known divergence handling** + +- R5. The three KOTOR1 romance components missing from the markdown source are carried as a documented exception list, not as test failures.

The C2 invariant — that an instruction file can be emitted as markdown and re-ingested without losing components, instructions, or option trees — is the technical foundation for this claim. + +Today, the three strongest roundtrip test suites are excluded from compilation in `src/ModSync.Tests/ModSync.Tests.csproj:91-93`.
