Import the canonical design docs (self / body / state-of-architecture) from
ephemeral uploads into docs/ so they survive a container reclaim, and update
them with this session's ETR decisions:
- ETR geometry organ -> GNU Octave (exception to the R default)
- ETR scaffolded invariants-first; cross-ref src/endocrine/etr/etr_invariants.md
- cross-organ drift/stress provenance (SAE -> EthInt-opposition -> stress
endomotiv -> drift / cross-axis coupling / full reshuffle / shift-rate)
