Move Interactive Mathematics deep-research PDF into projio + create handbook reference area

Task

Move (or copy) the ChatGPT Deep Research PDF Interactive Mathematics Beyond the Static Page from worklog into projio's handbook reference area. This PDF is the source of the conceptual frame adopted for handbook chapter 1 — see companion idea note (docs/log/idea/idea-arash-20260507-221835-382557.md) for the full synthesis.

Steps

1. Source: /storage2/arash/worklog/docs/reference/research/Interactive Mathematics Beyond the Static Page.pdf (22 pages, 197 KB, ChatGPT Deep Research output, dated 2026-05-07).

2. Destination: /storage2/arash/projects/projio/docs/reference/research/Interactive Mathematics Beyond the Static Page.pdf (or projio's existing convention for research-references — check runtime_conventions() first).

3. Use cp -L to dereference any datalad/git-annex symlinks (per CLAUDE.md "copying assets from datalad/git-annex projects" section). The source is in worklog which uses * annex.largefiles=((mimeencoding=binary)and(largerthan=0)), so the file is annexed.

4. Decide: leave a copy in worklog, or remove after migration. Default: remove from worklog (single source of truth in projio handbook reference).

5. Optional: ingest into projio's biblio if it deserves a citekey. It's a non-academic ChatGPT output, so probably no — but it could be added to a "reference materials" collection rather than the formal bibliography.

Why projio not workshop

The PDF is a reference for handbook chapter 1's conceptual frame ("Why interactivity matters for research practice"). The handbook lives in projio. Workshop materials reference handbook chapters, not the underlying research. So this PDF stays in projio.

Acceptance

• File present at projio reference path with content (not a broken annex symlink)
• Source removed from worklog OR explicitly retained with reason noted
• Cross-referenced from the idea note docs/log/idea/idea-arash-20260507-221835-382557.md if the path changes from the placeholder mentioned there
