test: true-parameter FIPC linking RMSE recovery gate - #264
Conversation
Pin buyer-visible recovery error for copied anchors versus old-form estimates and for unique new-form items versus generating 2PL parameters. Does not change autoFIPC() arithmetic. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This PR adds an RMSE recovery test without changing calibration behavior, but one assertion may fail before reporting useful diagnostics and the summary does not document assumptions that affect metric interpretation.

- Around line 7-11: Update the PR summary to document that simdata() uses a N(0,
1) theta scale and that autoFIPC() keeps linked unique items on this scale with
forceNormalZeroOne = TRUE and freeMEAN = FALSE. Also record that fixing anchors
to estimated old-form values means unique-item RMSE versus truth includes anchor
calibration error and a small scale discrepancy.
- Around line 114-139: Replace the RMSE expect_lt checks for anchor_copy_rmse,
old_recovery_rmse, and unique_linked_rmse with expect_true conditions using a
shared metrics diagnostic string. Include that metrics string via info for every
validation, and extend the finite-value check to include anchor_copy_rmse.

🌐 Web query:
In testthat version 3.0.0, does expect_lt() accept an info argument that is included in failure output?
💡 Result:
In testthat version 3.0.0, the expect_lt function does not accept an info argument [1][2]. The function signature is defined as expect_lt(object, expected, label = NULL, expected.label = NULL), and it does not include an info parameter [1][2]. While some legacy documentation for the testthat package may mention an info argument for various expectation functions, it is explicitly noted as soft-deprecated and discouraged for use in new code [3][4][5]. For modern testthat usage, users are directed to alternatives provided via quasi_label to customize failure messages [3][4][5].

The org Strix required workflow failed at visibility lookup: installation 141441800 exceeded the GitHub API rate limit (HTTP 403), so is_private was not true/false. No test change. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
testthat 3 expect_lt() has no info= argument. Move the three RMSE gates onto expect_true(..., info = metrics) and include anchor_copy_rmse in the finite check so a CI failure always shows the buyer-visible numbers. Also retriggers Noema after a GitHub HTTP 503 flake on the previous head. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
