Verification

Verified 2026-10-19 against Gitea issue #95.

Build and existing checks

• JAVA_HOME=/usr/local/software/java/jfx-25 ./gradlew build — passed, including normal Detag generation, compilation, packaging, and existing tests.
• Existing suite: 42 tests across six suites, zero failures, errors, or skips. No new automated tests were added.
• Repeated build after switching the display amount to the existing ΩAmountΩ tag — passed; generated Java remained identical and compilation/tests were up-to-date.
• openspec validate 95-display-perps-sample-positions --strict — passed.
• git diff --check — passed.

Isolated JavaFX inspection

A temporary preview outside the repository constructed the actual PerpsTab in nested Production/Test tabs in a 600 × 400 JavaFX scene, rendered snapshots, changed expansion/selection, and scrolled the table. The operational Hub and its services were not started.

• Inspected expanded, selected, scrolled, collapsed-group, and Test snapshots. Column headings and USD values are readable; the notice wraps without clipping and identifies Phoenix as illustrative.
• Eight positions appear under two wallets and four venue groups (14 visible tree rows when expanded). Both venues have multiple Long/Short samples.
• Position rows are faint green/red. Selected rows retain native selection styling and readable direction text.
• Collapsing wallet A reduces visible rows from 14 to eight; Test remains at 14 rows, confirming independent trees.
• Collapsing all venues leaves six group rows with blank direction/size cells and no residual direction colors after row reuse.
• Scrolling exposes the remaining positions with correct colors, directions, and sizes.

This verifies rendered scenes and programmatic control behavior. Mouse/keyboard operation in the running EMC application was not exercised.

Scope review

Implementation consists of the new package-private EMC PerpsTab and one placeholder replacement in EvelynMissionControlImpl. Source review confirms no Refresh control, network calls, service changes, sample refresh timeline, public API changes, configuration changes, or dependency changes. Changes remain local and uncommitted for owner review; the OpenSpec change remains active.
