Concrete benchmark-backed repros are now split out from this broader bindings/materialization request:

• Direct Cypher row lowering rejects scalar multi-alias projections from a single MATCH #981 Direct Cypher row lowering rejects scalar multi-alias projections from a single MATCH
• AST row select cannot reference edge alias properties after traversal #982 AST row select cannot reference edge alias properties after traversal

These came up while wiring the first official SNB Interactive subset in pyg-bench on the local staged fixture. If the eventual fix path is shared, this broader issue still looks like the right umbrella.

Partial progress landed in #1008.\n\nWhat is now covered:\n- direct Cypher connected multi-alias scalar projection ()\n- connected multi-pattern and bounded reentry cases that were surfacing as \n\nWhat remains open here:\n- the broader / generalized row-bindings architecture beyond the connected single-path / connected multi-pattern lane that intentionally targeted.\n\nSo should stay open as the wider umbrella, but the narrower user-visible blockers and are now resolved by #1008.

Correction to my prior comment: shell interpolation mangled the markdown.

Partial progress landed in #1008.

What is now covered:

• direct Cypher connected multi-alias scalar projection (Direct Cypher row lowering rejects scalar multi-alias projections from a single MATCH #981)
• connected multi-pattern and bounded WITH ... MATCH reentry cases that were surfacing as Cypher MATCH after WITH currently supports only a single trailing MATCH pattern #1006

What remains open here:

• the broader bindings_table / generalized row-bindings architecture beyond the connected single-path / connected multi-pattern lane that feat(cypher): add connected multi-alias row bindings #1008 intentionally targeted

So #880 should stay open as the wider umbrella, but the narrower user-visible blockers #981 and #1006 are now resolved by #1008.
