Rebuild ETR as a single point on three independent toroidal axes, per the
restart discipline (laws -> tests -> fit constants). All prior ETR numbers
(R port and the CC-BY PDFs) are disowned; nothing carried forward.
- src/endocrine/etr/etr_invariants.md: ETR laws (+/-50 wrap, per-axis [17,35]
bands, opposition direction, AI-originated drift) with certainty tags, plus
the cross-organ drift/stress provenance (SAE -> EthInt convictions ->
stress endomotiv -> reshuffle / shift-rate) captured as open seams.
- src/endocrine/etr/etr.m: wrap + restoring direction implemented (law);
restoring magnitude (RESTORE_GAIN) and cross-axis coupling left as explicit
TBD stubs, not invented.
- src/endocrine/etr/test_etr.m + run_etr_tests.sh: red tests encoding the laws.
12 pass (confirmed laws), 2 fail honestly (unfitted magnitude + convergence),
2 pending (unconfirmed coupling / no-zero-crossing).
Language: GNU Octave (GPL/copyleft, lightweight, native torus mod-wrap). Ada
rejected for ETR (proves discrete invariants; ETR is continuous torus
dynamics). Rest of the Drive-Box stays R.
