Memory as files, from day one: append-only reasoning threads — one per
concern, entries dated, never rewritten. Commits record *what* changed; the
threads record *why*. The rule that made everything after it possible: the
why survives.

*Backfilled 2026-08-14 from the working record. Receipt: commit `5d513a4` (2026-04-27) — the hash is public, the history is private; the binding verifies when it opens.*
