What problem does it solve? Research backlog candidates can consume expensive compute on Spikes or APM worktrees before anyone checks whether the idea is viable. This Skill provides a cheap front-door viability gate that scores triaged Discovery Harness candidates on topology justification, data feasibility, and novelty, producing a PROMOTE, PARK, or KILL decision before any compute is spent. ## Core Features & Use Cases - Adversarial Topology Gate: Axis 1 forces the scorer to argue the null hypothesis, requiring a genuine metric space, a falsifiable feature-to-claim mapping, and a named non-TDA baseline before PROMOTE is possible. - Three-Axis Scorecard: Produces a machine-readable assay_scorecard YAML block with Axis 1 gate results plus 0-3 integer scores for data feasibility and novelty/publishability. - Contract Validation: Validates scorecard blocks with extract_scorecard_block and validate_assay_scorecard, including explicit iteration for multi-application notes. - Use Case: After /scout-review marks a candidate state: triaged in vault/00-Meta/Discovery/_backlog.md, run the assay to decide whether it earns a Spike, gets parked for more evidence, or is killed at zero compute cost. ## Quick Start Assay the triaged candidate in the Discovery backlog and write its scorecard note with a PROMOTE, PARK, or KILL decision.
