Move subsystem mechanics (migrations, thesis gate, redaction, ingest,
email, packaging) out of AGENTS.md into docs/guides/<topic>.md, each
scoped by paths: frontmatter and symlinked from .claude/rules/ so Claude
Code lazy-loads them. AGENTS.md keeps whole-repo facts and universal
guardrails plus a one-line index per guide. Fix the inaccurate
".claude/ is gitignored" note — it is tracked.
Replace the hardcoded immense-voyage.local with $START9_BOX_HOST so the
real host lives only in local start-cli context, not the repo. Add a
Current state section for fast session orientation.
Add a concise day-one AGENTS.md (stack, exact build/run/test/deploy
commands, directory layout, conventions, Always/Never). Preserve the
existing CLAUDE.md project constitution as docs/ten31-constitution.md
(referenced from AGENTS.md) and point CLAUDE.md -> AGENTS.md so Claude
Code loads the canonical guide.
