Full VM installs and Test Sandbox full mode now record a short
post-install runtime observation (60s settle + 120s sampling) with an
explicit measured/unavailable/failed/interrupted status that never
rewrites install success. Adds the standalone scripts/measure-runtime.py
sampler, the measure-installed-runtime.py harness wrapper, E2E report
rendering, results-API summaries, CI coverage and METRICS.md accounting
boundaries.
Generate all four README tables from reviewed source and build snapshots, distinguish collection and asset sizes from runtime results, and remove unsupported footprint claims. Add a consistency check in CI and document how to reproduce profiling and measurements.
