2026-07-30 — Portfolio selection

Reviewed all twelve portfolio items and their dependencies. Selected RQ-COMM-003 because it is unblocked, has the highest score (14/15), unlocks RQ-COMM-001, RQ-COMM-006, and RQ-COMM-007, and reduces proxy-optimization risk.

2026-07-30 — Scope and hypotheses

Bounded the mission to the minimum defensible measure set for an immediate procedural task. Predicted unassisted correct completion as primary; critical errors, assistance, accuracy, and accessibility as guardrails; and time, workload, satisfaction, and confidence as diagnostics. Defined falsifiers: unscorable goal states, weak inter-rater agreement, excessive burden, and floor/ceiling effects.

2026-07-30 — Evidence and contradiction search

Reviewed ISO/NIST usability framing, NIST and FDA validation guidance, empirical subjective/objective divergence, and IES learning research. Searched specifically for evidence that time, satisfaction, or immediate performance could stand alone.

2026-07-30 — Updates

1. Downgraded time from general secondary outcome to conditional diagnostic: NIST states it is not relevant to validation unless time is critical.
2. Preserved satisfaction and workload as separate diagnostic constructs; neither substitutes for observed correctness.
3. Narrowed the delayed-transfer requirement: it gates learning claims, not immediate instruction-following claims.
4. Kept accessibility as a design, participation, and subgroup constraint rather than manufacturing an “accessibility score.”

2026-07-30 — Stop decision

Stopped the desk-research cycle at diminishing decision value. Task-specific reliability, sensitivity, burden, and accessibility cannot be established until RQ-COMM-001 supplies candidate tasks and an intended audience. The REP is therefore partial and the mission remains active.
