Second brain
Session memory lives in git under research/, not on a wiki. This page is a curated landing for the published book. Daily briefs and scratch notes stay on GitHub so the site does not pretend every session log is product documentation.
Published Track B research in the book (not session scratch): Linux AArch64 syscall gap (B2) (inspection only), ADR-035 (B3 process-model stance), ADR-033 (B4 ELF / auxv / PT_INTERP gap), and ADR-034 (B5 VFS concept compare). Not claiming Linux userspace. Not claiming dynamic Linux ELF. Not claiming a Linux filesystem.
| Vault | Where | Job |
|---|---|---|
| Procedure | .cursor/skills/ctos-*/ | How to do a repeatable job |
| Correction | .cursor/rules/ + hard constraints in AGENTS.md | Mistakes we must not repeat |
| Relationship | Docs cross-links (vision → architecture → ADR → roadmap → ledger) | How pieces connect |
| Daily Brief | research/daily-briefs/ | Handoff: where we stopped |
Session scratch: research/random-thoughts/. Do not treat scratch as the honesty ledger.
Tracker is GitHub. Optional Obsidian UI is local-only (.obsidian/ is gitignored). See research/README.md on GitHub.
