User description

Summary

Adds crates/sl-viewer/tests/properties_viewer_web_exports.rs with 11 proptest properties pinning the WebExportProvider reductions and web_export_roots_with_env discovery helper (WBS-6.2 #437, redux after the operator closed the original PR due to merge conflicts with #433's timeline surface).

WebExportProvider::label (3 properties) — non-empty, well-formed (no tabs/newlines/double-spaces), distinct.
WebExportProvider::corpus (2 properties) — total over the three *Web Corpus variants; injective.
WebExportProvider::default_subdir (3 properties) — non-empty, distinct, equals label().
web_export_roots_with_env (3 properties) — empty set for missing home; returns the existing-default subset; returns all three providers when all defaults exist.

Validation

  • cargo test -p sl-viewer --test properties_viewer_web_exports --features "desktop parquet" --locked — 11 passed
  • cargo clippy -p sl-viewer --test properties_viewer_web_exports --features "desktop parquet" --locked -- -D warnings — clean
  • cargo fmt --all --check — clean

Rebase status

This branch was rebased onto origin/main after #433 (timeline) was merged. Conflicts in CHANGELOG.md, docs/ops/WBS.md, docs/ops/TRACEABILITY.json were resolved by keeping both #433 and #437 entries.


CodeAnt-AI Description

Add property coverage for viewer web-export discovery and provider mappings

What Changed

  • Added 11 property tests covering provider labels, corpus mappings, default download folders, and web-export root discovery
  • Verifies labels and folders are distinct, non-empty, and consistently named for ChatGPT, Claude, and Gemini exports
  • Verifies each provider maps to its matching web corpus and that discovery returns only existing default folders, exactly once
  • Documented the new coverage in the work plan, traceability records, and changelog

Impact

✅ Fewer web-export configuration regressions
✅ Consistent provider names and download folders
✅ Reliable discovery of available export folders

Adds `crates/sl-viewer/tests/properties_viewer_web_exports.rs` with
11 proptest properties pinning `WebExportProvider` and
`web_export_roots_with_env` reductions:

* `WebExportProvider::label`:
  * Non-empty.
  * Free of tabs / newlines / double-spaces (well-formed for badge UI).
  * Distinct per variant (no accidental aliasing).
* `WebExportProvider::corpus`:
  * Total — every variant maps to a `Corpus::ChatGptWeb | ClaudeWeb |
    GeminiWeb` value (no panics, no fallback).
  * Injective — distinct providers map to distinct corpora.
* `WebExportProvider::default_subdir`:
  * Non-empty.
  * Distinct per variant.
  * Equals `label()` — `~/Downloads/<subdir>` lines up with the
    user-facing provider name.
* `web_export_roots_with_env(home, None)`:
  * Empty set when `home` is non-existent.
  * Returns the subset of defaults whose `Downloads/<subdir>` path
    exists on disk, exactly once each, in default order.
  * Returns all three documented providers when all default dirs exist.

Updates WBS-6.2 evidence list, TRACEABILITY.json, and CHANGELOG.

Warning

Review limit reached

@KooshaPari, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 56 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Suggestion: The corpus properties only check membership and injectivity, so a permutation such as mapping ChatGpt to Corpus::ClaudeWeb would still pass. Assert each provider's exact expected corpus to prevent loading exports under the wrong corpus identity. [logic error]

Severity Level: Major ⚠️
- ⚠️ Corpus regression tests accept provider identity permutations.
- ❌ Exports could be loaded under the wrong corpus identity.
- ⚠️ Provider-specific filtering and reporting could become incorrect.

Suggestion: This test verifies discovery only for directory entries, but web_export_roots_with_env accepts any existing filesystem entry while load_web_export_corpus requires a directory and calls read_dir. Add a regular-file case and assert the intended behavior, otherwise the test suite will not catch discovery returning an unusable root. [incomplete implementation]

Severity Level: Major ⚠️
- ⚠️ Default discovery accepts unusable regular-file roots.
- ❌ Web export loading fails for that provider.
- ⚠️ User exports may be skipped with an error.
