The sensing pass of the portfolio-pdlc operating system. Use when asking "where is everything really, and is it outcome-oriented or activity-oriented?" — full portfolio reads, review/investment-council prep, stale-status sweeps, or restoring board integrity after contract violations. Verifies stages against evidence, classifies every card on the input→impact ladder, reads flow and risk balance, and outputs a review brief with ranked candidate moves. Composes the sniff-test and sniff-test-portfolio skills included in this repo.
