Replaces the single restoring spring with Anja's radial map: SNAP_IN(<7)
/ SOFT(7-17) / BAND(17-35) / INCOH(35-45) / SNAP_OUT(>45), unstable
watersheds at 7 and 45. Basin restores toward band centre 26 with a weak
SOFT gain (0.25) and firmer INCOH gain (0.5). A snap flips to the
opposite pole, landing just past the opposite watershed (inner -> opp.
SOFT; outer -> opp. INCOH) then recovering. Realises L7 (flips only via
snap zones — through 0 or over the wrap) and L8. Lone PEND: L5 coupling.

Spring restoring force (gain 0.5) toward band centre 26, active only out
of band; pulls the basin into [17,35] in a couple of steps without
overshoot. Closes the two red tests (L3 magnitude, L2 convergence).
NOTE: superseded design incoming — Anja's 4-zone bistable axis (snap
<7 / soft-pull 7-17 / stable / incoherency 35-45 / snap >45) will fold
this in as the soft-pull gain and revise L7.

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.
