fix(trg): stop held-out cases from leaking and eval gates from failing open - #229
Conversation
…t fix A test split that never ran read the same as one that ran and came back flat, so a suite with no held-out cases at all failed --fail-on overfitting on every train-side improvement, for a reason no held-out set could ever clear. Signed-off-by: Yordis Prieto <yordis.prieto@gmail.com>

…hat never ran A --split train or --case selection narrowed a suite down to none of its declared test cases still let removed_eval_ids and held_out fall back to treating the suite as if it had no held-out set at all, instead of saying the cases were declared but not covered by this run's selection.

…report.json unreadable Renaming ModelCaptureStatus::Partial to Incomplete meant a report.json an older build wrote no longer parsed anywhere it was read back: grading, scaling, and the cache's exact-hit lookup. The retired spelling is accepted on the way in without ever being written back out, so a build never has to be re-run just because the tool that reads its report.json moved on.

Merge Risk: 🔵 Low · up to The withholding option can reveal a formerly held-out case after its split changes. Filter those train details before relying on the option for changed-suite comparisons. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Held-out details are better protected in the updated workflow, but a CI gate configured to fail on overfitting alone can now pass when a suite declares held-out cases but does not run them. The impact appears limited to evaluation decisions and artifacts; broader exposure has not been established. Retained concerns

- Around line 244-245: Update deserialization of CaseSelection.declared to
accept legacy string-array entries while preserving their split as unknown
rather than defaulting to Train; ensure split-aware consumers of declared
entries do not treat unknown splits as train cases.
Review comments at @crates/trg/src/agentskills/eval_suite_drift.rs:
- Around line 152-154: Update recorded_declared_case_ids to read case IDs from
both string entries and object entries in suite.case_selection.declared, using
each object’s id field when present. Preserve handling of existing string
entries so the collected IDs remain available to the drift snapshot.
Review comments at @crates/trg/src/agentskills/iteration_summary.rs:
- Around line 375-442: Update build_iteration_summary_document and
withhold_test_split_detail to include test case IDs from both the current and
previous reports when withholding detail; preserve the existing behavior when no
previous report is available.

… drift when read back as objects
A held-out case only survives in the declared list, and reading that list back
as raw JSON to find the previous report silently dropped every entry once the
list started holding {id, split} objects instead of bare strings, so the
held-out case fell back into looking like added or removed suite drift.
Signed-off-by: Yordis Prieto <yordis.prieto@gmail.com>
A declared case only started carrying its split once report.json grew {id,
split} entries, so a report an older build wrote as a bare id list could no
longer be deserialized at all, breaking grade, improvement-bundle, scaling
and cache reads of it. An id whose split was never recorded must also never
be guessed as train, since that is exactly the guess that would let a
held-out case leak.

…-iteration detail Withholding only checked the current report's own runs for which cases are test-split, but the cross-iteration section it also has to mask draws its case ids from the previous report. A narrower selection that stopped running a held-out case did not stop that case's id and assertion text from showing up as newly regressed or improved.
