StellaOps Bot 47168fec38 feat: Add VEX compact fixture and implement offline verifier for Findings Ledger exports 
- Introduced a new VEX compact fixture for testing purposes.
- Implemented `verify_export.py` script to validate Findings Ledger exports, ensuring deterministic ordering and applying redaction manifests.
- Added a lightweight stub `HarnessRunner` for unit tests to validate ledger hashing expectations.
- Documented tasks related to the Mirror Creator.
- Created models for entropy signals and implemented the `EntropyPenaltyCalculator` to compute penalties based on scanner outputs.
- Developed unit tests for `EntropyPenaltyCalculator` to ensure correct penalty calculations and handling of edge cases.
- Added tests for symbol ID normalization in the reachability scanner.
- Enhanced console status service with comprehensive unit tests for connection handling and error recovery.
- Included Cosign tool version 2.6.0 with checksums for various platforms.

Graph UI Bench Plan (BENCH-GRAPH-21-002)

Purpose: provide a deterministic, headless flow for measuring graph UI interactions over large fixtures (50k/100k nodes).

Scope

  • Use synthetic fixtures under samples/graph/interim/ until canonical SAMPLES-GRAPH-24-003 lands.
  • Optional overlay layer (overlay.ndjson) is loaded when present and toggled during the run to capture render/merge overhead.
  • Drive a deterministic sequence of interactions:
    1. Load graph canvas with specified fixture.
    2. Pan to node pkg-000001.
    3. Zoom in 2×, zoom out 1×.
    4. Apply filter name contains "package-0001".
    5. Select node, expand neighbors (depth 1), collapse.
    6. Toggle overlay layer (once available).
  • Capture timings: initial render, filter apply, expand/collapse, overlay toggle (when available).

Determinism rules

  • Fixed seed for any randomized layouts (seed 424242).
  • Disable animations/transitions where possible; otherwise measure after requestAnimationFrame settle.
  • No network calls; fixtures loaded from local file served by test harness.
  • Stable viewport (width=1280, height=720), device scale factor 1.

Artifacts

  • ui_bench_scenarios.json — canonical scenario list with step ids and notes.
  • ui_bench_driver.mjs — helper that reads scenario + fixture manifest and emits a run plan (no browser dependency). Intended to be wrapped by a Playwright script later.
  • Results format (proposed): NDJSON with {stepId, name, durationMs, fixture, timestamp}.

Next steps

  • Bind ui_bench_driver.mjs into a Playwright harness when Graph UI build/serve target is available.
  • Swap fixtures to SAMPLES-GRAPH-24-003 + overlay once schema finalized; keep scenario ids stable.
  • Add CI slice to run the driver and validate scenario/fixture bindings (no browser) to keep determinism checked in commits.
