) Follow-up to #264 review (johanpel): let the analyzer detect the artifact's serialization format instead of threading it through `quent-open`. `QuentViewer::import_events` and the `model!`-generated `import_events` now take just the context directory and detect the format from the on-disk streams (new `quent_exporter::FileSystemFormat::detect`). The server's `index_query_engines` detects per-context too. The generated viewer wrapper enables all exporter formats so any artifact opens, and `quent-open` drops `Format`/`detect_format` and the format component of its cache key. **Breaking:** `QuentViewer::import_events` / `Model::import_events` drop the `format` argument; `index_query_engines` drops its `format` parameter. Downstream `QuentViewer` impls (e.g. sirius) drop the `format` param and call `Model::import_events(dir)`. **Compatibility:** `quent-open` builds the wrapper against the quent/analyzer commits pinned in `model.qmi` and now emits the one-argument calls, so it can only open artifacts whose pinned commits already include this change. Artifacts pinned to earlier commits (from the pre-release window) won't build a viewer — an accepted consequence of this breaking change; versioning the sidecar/codegen against the pinned API is left as future work. Off `main`, independent of the merged quent-open work (#265) and the open stack (#266/#273/#276). Whichever of this PR and that stack lands second needs a rebase — both touch `quent-open`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Authors: - Matthijs Brobbel (https://github.com/mbrobbel) Approvers: - Johan Peltenburg (https://github.com/johanpel) URL: #277
`FileSystemFormat::detect` (added in rapidsai#277, currently untested) recognizes an artifact's format from the streams on disk. Cover it with an integration test that drives the real filesystem exporter — laying out `<root>/<entity>/<uuid>.<ext>` — rather than hand-fabricating an `events.<ext>` layout the exporter never writes. Originally proposed against `quent-open` (johanpel review, rapidsai#264); rapidsai#277 moved format detection out of `quent-open` into the exporter, so the test moves with it.

📝 WalkthroughWalkthroughThe IO crate adds development dependencies for temporary files and Tokio. An async integration test verifies that format detection identifies Msgpack filesystem exporter output. A previous single-format unit test was removed, while mixed-format rejection coverage remains. ChangesFormat detection testing
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to This change improves format-detection coverage by exercising the real exporter layout. No actionable merge-blocking risk remains; minor test setup error handling and dependency-convention cleanup can be addressed as routine follow-up.
