Run the Obsidian collector against unprocessed daily notes: ``` python3 studio/collectors/obsidian_collector.py ``` If the user passes `--all`, add that flag to reprocess all notes (including already-archived ones in `processed/`). If the user passes `--dry-run`, add that flag to preview without writing or moving files. Side effects of a real (non-dry-run) run: - Routes items to spec stubs / Ideas/ / feature backlog as before - Records every extracted `#tag` (not just the routed ones) to `studio/collectors/obsidian_tagged_items.json` as structured data — one record per `{tag, text, date, source}`, deduplicated - Moves each processed daily note into `processed/` inside the vault (lowercase — do not rename to `Processed/`, a differently-cased folder already exists from before this feature and collides on case-insensitive Dropbox sync) After running, report: - How many spec stubs were created and their names - How many ideas were filed and to which topic files - How many tagged items were recorded to the structured data file - Any duplicates skipped If new spec stubs were created, list them and ask if the user wants to open any for editing.
