JSON and Config Regression

Use this skill when editing IccJSON/, JSON serialization, or -cfg handling for iccApplyNamedCmm, iccApplyProfiles, or iccApplySearch.

Fail-Closed Rules

Reject short fixed-size arrays instead of truncating.
Reject non-numeric values for required numeric fields.
Propagate failed nested ParseJson() or fromJson() calls.
Reject bad struct members instead of skipping them.
Reset stale state before parse and honor reset/fromJson flags.

Validation

Run the focused gates from the repository root after building tools:

ICCDEV_TOOLS_DIR=$PWD/Build/Tools ICCDEV_TESTING_DIR=$PWD/Testing .github/scripts/iccdev-json-parser-regression-tests.sh
ICCDEV_TOOLS_DIR=$PWD/Build/Tools ICCDEV_TESTING_DIR=$PWD/Testing .github/scripts/iccdev-json-cfg-tests.sh

If observer/profile behavior is involved, also run:

ICCDEV_TOOLS_DIR=$PWD/Build/Tools ICCDEV_TESTING_DIR=$PWD/Testing .github/scripts/iccdev-stdobserver-regression-tests.sh

Review Checklist

Verify exact CLI command names and config keys.
Add malformed tests for rejected input.
Confirm success paths still round-trip valid profiles/configs.
Keep test output reproducible from the repository root.
