…ses, module shrunk to 2 residuals New dsl/test/claim/map_lookup_dual_dispatch_witness_test.dag carries the three lookup-surface checks + std.graph adjacency smoke as marker-discovered test fns. Perturb receipt at the live realization layer: raw_map_lookup (v1_interpreter.rs:6256, the dual-dispatch chokepoint) forced to always miss reds all four witnesses (also proving the routing claim). Residuals: the source-scan bypass wall (pinned harness) and the #[ignore]d empty-list inference case (pre-existing bug, bucket=inference). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Six rows were listing modules as full-debt after they had already partially or fully migrated (per #6140/#6142/#6143/#6145/#6147/#6150/#6153): render_repeat, cron_tag, money_carrier_cost_witness are fully deleted from src/v1/tests/src/lib.rs (removed from table); fn_as_value_test, witness_option_bridge_test, map_lookup_dual_dispatch_test, coproduct_reflection_conformance_test shrunk to small pinned residuals (LOC/test counts corrected against current main).

Tenth PR of the 5-test-migration lane. This slice closes only the map_lookup_dual_dispatch module; the lane node stays open.
What
dsl/test/claim/map_lookup_dual_dispatch_witness_test.dag: four marker-discoveredtest fns — the three map-lookup surfaces (m |> get(k),m[k]index sugar,lookup(m,k)builtin) and thestd.graphadjacency-view smoke that consumesmap_getend-to-end.src/v1/tests/src/map_lookup_dual_dispatch_test.rs175→~75 LOC, 6→2 tests.Residuals (documented in module header)
map_lookup_operations_do_not_probe_value_map_outside_chokepoint: scansv1_interpreter.rsfor forbidden nativeValue::Mapprobe patterns — a pinned-harness fact, dissolves with the v1 interpreter.map_get_function_returns_optional_for_empty_list_hit: already#[ignore]d on a pre-existing empty-list-literal inference bug (bucket=inference, surfaced by Widen the rust gate by construction (§1): invert the hand-picked 3-filter allowlist (29 of 792 green tests) → run-all-unless-#[ignore]d-with-written-reason; add CI-coverage-completeness so a new test is covered by default (fail-closed); measure CI-time impact before committing the full set #5427); migrates when the bug is fixed and the witness can land green.Receipts (green-by-execution + perturb→red, layer justified)

A temporary Rust commit forcing it to always miss reds all four witnesses (exit 1), which simultaneously proves the routing claim the v1 tests asserted (every surface goes through the chokepoint).
