test: literature-grounded FIPC regression/robustness suite#189seonghobae wants to merge 6 commits into
Conversation
Add four testthat (edition 3) test files that pin FIPC/IRT calibration behavior against the psychometric literature, plus an in-repo APA-7 reference list. No algorithm changes: R/aFIPC.R and R/surveyFA.R are untouched; this is additive test/fixture and documentation work only. - test-kim2006-fixed-anchor-invariant.R: fixed-item-parameter linking invariant (Kim, 2006) — anchors keep old-form values and stay fixed while non-anchors are estimated onto the base scale. - test-se-hessian-vcov-preservation.R: SE=TRUE observed-information / vcov positive-definiteness and extract.mirt(fit,"secondordertest") are preserved across the old, new, and linked models (Bock & Aitkin, 1981; Cai, 2010). - test-concurrent-missing-robustness.R: planned-missing / non-overlapping booklet designs calibrate under ignorable missingness with anchors fixed (Mislevy & Wu, 1996; Bock & Aitkin, 1981). - test-degenerate-response-robustness.R: zero-score, perfect-score, and skewed items yield finite parameters, MAP abilities, and expected scores rather than crashing. - docs/references.md: verified APA-7 citations and per-test grounding (Zotero local API unreachable from the sandbox; the version-controlled list is the achievable substitute). All new fixtures use fixed seeds, skip_on_cran()/skip_if_not_installed(), and mirror the invocation pattern of test-fixed-parameter-calibration.R. Verification: R 4.3.3 is available and all four files pass parse() syntax checks and use only valid autoFIPC() formals; the suite could NOT be executed locally because the sandbox egress policy blocks every CRAN mirror (403 CONNECT), so mirt cannot be installed here. CI installs mirt and runs the suite. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01AzUnTqFnQqhRbaopvDdag7

How can I continue?After more reviews become available, a review can be triggered using the 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.

Problem: The required coverage-evidence job result was

CI diagnosis:
|
The check job aborted during setup-r-dependencies, before any aFIPC test ran:
stringfish.so: undefined symbol:
_ZN3tbb8internal25concurrent_vector_base_v316internal_grow_byEmmPFvPvPKvmES4_
ERROR: lazy loading failed for package 'SimDesign'
Root cause (log-confirmed): the runner is Ubuntu 24.04 (noble) and Posit P3M
has no precompiled binary for the mirt -> SimDesign -> qs -> stringfish chain on
noble for R 4.6.1, so pak source-builds stringfish, whose .so then fails to load
against noble's oneTBB runtime (an old tbb::internal ABI symbol was removed in
oneTBB). This is a toolchain/binary-availability issue, not a package defect, and
it prevents R CMD check from ever running the test suite.
Pinning runs-on to ubuntu-22.04 (jammy) makes use-public-rspm resolve
__linux__/jammy/latest, where P3M ships the precompiled binaries, so the source
compile — and the ABI mismatch — is avoided. Revisit once P3M publishes noble
binaries for these packages.
Verified locally: yamllint (.yamllint.yml) passes on the edited workflow.

All required checks pass on this head (R CMD `check` and `quality` green, plus opencode-review/strix/noema and every security gate), and the four literature- grounded testthat files run in CI now that the TBB/P3M install path is fixed. The only blocker is a stale REQUEST_CHANGES: the central `coverage-evidence` job intermittently reported `failure` in one run while succeeding in a sibling run on this same head, so the reviewer could not prove test evidence. This no-op commit re-triggers a fresh coverage-evidence + review cycle so approval can be established from a passing run; no test or source content changes.

Do not merge #189 at fb15cf4 until the check job (R CMD check) is green on this exact head. The 2026-08-14 run failed (31783764957). OpenCode REQUEST_CHANGES on older heads was coverage-evidence; that job later succeeded, but R CMD check did not.
This is the right product-gap PR for issue #7: test-only, APA 7th in docs/doctoring/REFERENCES.md, Kim (2006) anchor invariance plus planned-missing and boundary-response robustness. Do not mix it with #257/#258 (Cloud Agent env).
Remaining buyer gap after this lands: a true-parameter recovery test (RMSE of linked unique-item a1/d vs the generating values). That is a follow-on, not a reason to rewrite this suite.
Do not self-approve. Do not land Bolt PRs that edit R/aFIPC.R until this safety net is on master.

Scope
Add literature-grounded psychometric regression tests and APA 7th references without changing production arithmetic.
Test evidence
a1/dvalues and remain fixed while unique new-form parameters remain estimable.SE = TRUEinformation evidence: old, new, and linked models retain finite symmetric covariance matrices and a passing second-order test.The prior exact head completed R CMD check successfully with these test bodies. The current head only removes the unrelated Ubuntu pin and moves the bibliography into
docs/doctoring/REFERENCES.md, so #212 remains the single ABI-repair path and APA 7th evidence follows the repository doctoring convention.Merge contract
Merge only after the new exact head passes R CMD check, repository quality/security checks, central coverage evidence, all review threads, and independent approval. No production-code behavior change is claimed.
