test: TestProject array_* builders accept a subscript over an undeclared dimension, so a fixture can pass on a model that never compiles

Status: Open.

engine: ltm_discovery_mode is still a salsa input; flipping it discards the other mode's memos

Status: Open.

#1056 In bpowers/simlin;

· bpowers opened on Sep 5, 2026

engine: XMILE 1.0 section 4.7.1 bare <connect to="Input"> (the spec's own module-input spelling; Stella 10.0.6 writer) binds no port -- BadModuleInputDst warning, empty_equation refusal; only Stella's module-qualified to= wires

Status: Open.

· bpowers opened on Sep 4, 2026

engine: SUM(pop[coast]) with coast a subrange the target does not range over is refused as "mismatched_dimensions -- pop" -- the diagnostic names the variable, not the subrange or the *:coast spelling that compiles

Status: Open.

#1052 In bpowers/simlin;

· bpowers opened on Sep 4, 2026

engine: reducer over a scalar-shaped expression is refused (SUM(pop * 2) in an apply-to-all body, SUM(s * 2)) where SUM(pop) * 2 compiles -- the materializer declines a 0-d operand; origin/main computes it x|D|

Status: Open.

#1051 In bpowers/simlin;

· bpowers opened on Sep 4, 2026

engine: variable-vs-dimension name collision is never refused at definition; each spelling resolves it differently (plain read accepted, PREVIOUS/INIT refused, bare read silently yields the element index)

Status: Open.

docs: full verification pass of ltm--loops-that-matter.md against the LTM code (build_partial_equation is gone; recompute passage describes the adapter, not ModuleOverrideCache; module-role taxonomy is prose-only)

Status: Open.

engine: same-instance XMILE <connect> (from=bridge.output to=bridge.input) has no settled meaning; binds nothing + BadModuleInputSrc warning since V9a-2
