A single demo that walks the full 3 × 3 × 2 matrix (register × lens
× prompts, 18 cells) and pins five claims simultaneously, packaging
both single-axis invariants into one composition gate.
The single-axis tours assert opposite invariants:
register-tour : per (lens, prompt), trace_hash CONSTANT across
registers (R5 / ADR-0072).
anchor-lens-tour : per (register, prompt), engaged lens diverges
in trace_hash from the unanchored baseline
(L1.4 / ADR-0073d).
Orthogonality-tour packages both claims simultaneously across the
full matrix, plus three surface-level claims that pin the markers
operators actually see.
Composed claims (all five must hold)
A) inner_register_invariant_within_lens
For each (lens, prompt) cell, the three register runs share an
identical trace_hash. (R5 register-tour, applied 6 times:
3 lenses × 2 prompts.)
B) outer_lens_distinctness_within_register
For each (register, prompt) cell where any non-unanchored lens
engages, that engaged lens's trace_hash differs from the
unanchored baseline at the same (register, prompt).
(L1.4 anchor-lens-tour, applied 6 times: 3 registers × 2 prompts.)
C) surface_carries_register_marker_under_convivial
Every convivial cell with a non-empty surface has a non-empty
register_variant_id.
D) surface_carries_lens_annotation_when_engaged
Every engaged cell carries [lens(<id>):<mode>] in surface AND
a non-empty anchor_lens_mode_label.
E) no_substrate_glyph_leak_across_grid
No cell's surface contains Greek/Hebrew/Syriac/Arabic glyphs.
(ADR-0073c gate re-asserted across the full matrix.)

Sanity check baked into tests
test_engaged_cells_appear_for_both_non_trivial_lenses pins that
grc_logos_v1 engages on knowledge in all 3 registers (3 cells)
and he_logos_v1 engages on truth in all 3 registers (3 cells).
Prevents the lift claims being vacuously satisfied by a future
engagement regression.
Lane evidence
- 9 new orthogonality-tour tests pass.
- core demo register-tour → all_claims_supported: True
- core demo anchor-lens-tour → all_claims_supported: True
- core demo orthogonality-tour → all_claims_supported: True
- python -m core.cli eval cognition → byte-identical 100/100/91.7/100.
- Full lane: 2745 passed / 4 skipped / 1 pre-existing failure
(+9 over L1.4's 2736; the one failure remains
test_all_preamble_explains_combined_run, unrelated).
No runtime / composer / loader / pack / schema changes. Pure demo
consumer of existing telemetry contracts.
