Team review anchor: research foundations, prototype, ADRs, and kickoff

[espi]

Note: main was created at this branch's tip, so all substantive work is already on main — the diff here is only a small doc fix. Treat this PR as the review anchor and reading guide for everything that landed.

What's on main (by commit)

• d3c4548 — Source assets + analysis for the two social posts: the Instagram "leaked Obsidian vault" case study (analysis) and the Marble Skill Taxonomy release (analysis, verify script), plus the 18 strategy questions.
• 7b88f5c — Working answers to all 18 questions, grounded in computation on the real dataset. Start with the index's dataset-facts box (standards-coverage gaps, Computing-has-no-programming, centrality outlier).
• d1b171d — Team enablement: runnable frontier/remediation prototype, pinned Marble snapshot (ODbL — read its rules), decision log with 3 seed ADRs (challenge window closes 2026-07-23), and the 30-minute kickoff agenda.

How to engage

1. 5 min: python3 prototypes/frontier_demo.py --mastered-through-age 6
2. 15 min: read the foundations index
3. Claim an issue: #1–#16 — three are kickoff blockers, the rest resolve async
4. Challenge an ADR before 2026-07-23, or silence ratifies

Diff in this PR

One line: the kickoff agenda now points post-meeting discussion at the issues (the original text assumed this PR would carry the doc review, but the docs merged with main's creation).
