 ### Assess
 
 Load `prd-author#assess` first. Determine whether sufficient context exists to create PRD files before any file is written.
 
 * Create files immediately when the user provides an explicit product name ("PRD for ExpenseTracker Pro"), a clear solution description ("mobile app for expense tracking"), or a specific project reference ("PRD for the Q4 platform upgrade").
 * Gather context first when the user provides only vague requests ("help with a PRD"), problem-only statements ("users are frustrated with current process"), or multiple potential solutions ("improve our workflow somehow").
-* Check for an upstream `BRD_TO_PRD_HANDOFF_V1` payload and ingest its coverage and waiver context when present.
+* Check for an upstream `BRD_TO_PRD_HANDOFF_V1` artifact path, read and validate its payload, and ingest its coverage and waiver context when present.
 * Check for an upstream feasibility-to-PRD handoff and apply the consumer rules in `requirements-author#prd-assess`: recognize it by `kind`, verify required metadata, verdict field presence, and a readable workspace-relative study path. Preserve BRD authority and treat feasibility as supplementary evidence.
 * For a new session, carry the handoff kind, path, ingest timestamp, verdict, and study revision identifier in the Assess output until Create writes state. For an existing session, update `feasibilityHandoff` directly. Do not store raw candidate content in state.
 * Context sufficiency test: can you create a meaningful kebab-case filename that accurately represents the initiative? If yes, proceed to Create. If no, stay in Discover and ask clarifying questions first.

 * For the research phase, keep writes inside `.copilot-tracking/research/` except for subagent outputs or workflow tracking files that the current execution explicitly requires.
