# Build the source inventory Use when `source-intake` is the current gate. - Read repo instructions and nearby handoff docs first. - Keep the source folder read-only. Create working notes only in the presentation work area. - Read existing deck, source, and work artifacts before creating new ones. - Inspect file contents with structured tools appropriate to each type: PDF, PPTX, DOCX, spreadsheet, image, script, note, and export. - Classify every relevant item by role, recency, and reuse value instead of copying folders into the work area. - Identify version lineage: draft, revision, export, derivative, duplicate, and latest known source. - Mark the most authoritative source for each topic, chart, claim set, and visual asset. - Record reusable assets that can move forward without rework. - Record stale materials that should not drive current decisions. - Record conflicts, missing files, and access blockers explicitly. Write `SOURCE-INVENTORY.md` from `templates/SOURCE-INVENTORY.md`. - Fill every section with concrete paths, dates when visible, and short evidence notes. - Prefer exact filenames over vague summaries. - If discoverable answers exist in the files, find them before asking the user. - Stop after the inventory is complete enough for product grilling to begin.
