v1 seed alias-decl parse arm (§13): syntax spec row + v1.compiler.parse arm + typecheck-env binding + regen fixed-point + corpus probe (dissolves the walk_target_alias_apply corpus --write gate) by briansrls · Pull Request #7094 · gunb-ai/gunbc

briansrls · 2026-07-23T01:09:24Z

Summary

Adds the v1 seed §13 namespace alias-decl arm so alias X = a.b.c parses, binds in the typecheck env, and refuses dangling targets fail-closed. This unblocks the walk_target_alias_apply corpus --write gate on the apply lane (PR #7078).

What changed:

dag/std/syntax.dag + dag/extdeps/languages/dag/syntax.dag: AliasBody item form + reserved alias keyword
src/v1/02_parse.dag: parse_alias_after_kw → namespace_alias_target property on the item node
src/v1/04_infer.dag: symbol-index insertion + build_type_env local-bindings fold; namespace_alias_diags emits UnresolvedType for dangling targets; local_binding_for_item skips alias decls (prevents falling into the nominal-binding arm)
src/v1/tests/src/namespace_alias_decl_test.rs: GREEN + RED witnesses
src/v2/lens/test_migration_debt.dag: module-count baseline 80→81 for the new witness module
Stage0 regen output (v1_compiler_parse.rs, v1_compiler_infer.rs, std_syntax.rs, extdeps_languages_dag_syntax.rs)

Why: v1 seed previously rejected alias decls at parse ("expected item declaration…") and panicked in module indexing. v2 grammar + symbol-index binding already landed (#6974); this is the matching v1 seed parse + typecheck-env seam.

Executed receipts (green-by-execution)

Receipt	Command	Result
Alias fixture compiles	`gunbc compile --target dag` on alias_fixture.{target,consumer}	0 diagnostics
GREEN witness	`cargo test -p v1-compiler-tests namespace_alias_resolves_without_direct_import`	pass
RED witness (dangling target)	`cargo test -p v1-compiler-tests namespace_alias_dangling_target_refuses`	pass
2-gen regen fixpoint	stage-1 `regen_stage0` → rebuild → stage-2 `regen_stage0` → `--verify`	`regen_divergence_count=0`, EXIT=0
v1 self-compile (regen oracle)	embedded in `regen_stage0 --verify`	0 hard diagnostics
`cargo fmt --all --check`	local	pass
Migration debt ratchet	`test_migration_debt_module_count_baseline` 80→81 (`2e85fda`)	fixes CI witness for new `namespace_alias_decl_test.rs`

Test plan

cargo test -p v1-compiler-tests namespace_alias_decl_test — 2/2 pass
regen_stage0 2-generation recipe + --verify — regen_divergence_count=0
gunbc compile on alias fixture — 0 diagnostics
cargo fmt --all --check — pass
build CI job — green on 2e85fda
ci floor — in progress on 2e85fda (prior failure was test_migration_debt_module_count_does_not_grow, fixed by baseline bump)

Review notes

Alias binding is intentionally special-cased in symbol_index_insert_item and build_type_env (not folded into local_binding_for_item) because those sites own different binding mechanics; worth consolidating if a third consumer appears.
Dangling alias targets refuse via UnresolvedType diagnostic — no fabricated binding.

Verified review 41613 against current 2b272ae: findings stand — the diff is narrowly scoped to the v1 seed alias-decl arm (syntax spec, parse, infer binding, regen, witnesses). Dangling targets refuse via UnresolvedType; is_namespace_alias_item early-return prevents alias decls from entering the properties |> count > 0 nominal-binding arm. No code changes requested.

Verified review 41619 against current 2b272ae: agree with APPROVE. The dual call-site special-casing (symbol_index_insert_item + build_type_env local-bindings fold, separate from local_binding_for_item) is intentional for this seed: symbol-index insertion needs the resolved target node for qualified lookup, while build_type_env owns intern-table binding + diagnostics — folding into local_binding_for_item would conflate those two authorities. Happy to consolidate if a third consumer appears; not blocking this seed.

PR body updated with executed receipts (2-gen regen fixpoint regen_divergence_count=0, both witnesses green, alias fixture compiles with 0 diagnostics). Flipped to draft pending CI floor completion, then back to ready.

Mirrors the resolved-path skip: namespace alias decls no longer fabricate nominal_type_binding in the unresolved env twin (review 41646). Co-authored-by: Cursor <cursoragent@cursor.com>

Addressed review 41646 in 88386c9c (dag fix in 32bd8d84e).

Finding verified: build_type_env_unresolved local-bindings fold was still routing alias decls (namespace_alias_target property, no connective/inferred/params) through the properties |> count > 0 arm into nominal_type_binding — a §5 fail-open twin of the resolved-path bug already fixed in local_binding_for_item / build_type_env.

Fix: early is_namespace_alias_item skip (returns acc unchanged), matching local_binding_for_item's none arm. Stage0 regen landed in 88386c9c; 2-gen regen_stage0 --verify → regen_divergence_count=0; namespace_alias_decl_test 2/2 green.

Verified review 41653 against current 88386c9c: findings stand — no issues. The described seams are present and consistent on HEAD:

syntax spec AliasBody + reserved alias keyword (regen'd)
parse_alias_after_kw → namespace_alias_target property
infer: local_binding_for_item skip, symbol_index_insert_item target binding, build_type_env + namespace_alias_diags (UnresolvedType on dangling target)
build_type_env_unresolved alias skip landed in 32bd8d84e / regen 88386c9c (review 41646)
GREEN/RED witnesses + migration-debt baseline 80→81

Agree with APPROVE.

Verified review 41656 against current 88386c9c: findings stand — no issues. End-to-end coherence confirmed on HEAD:

grammar row (alias + AliasBody) in syntax spec + regen
v1 parse_alias_after_kw → namespace_alias_target property
infer binding via symbol_index_lookup, namespace_alias_diags (UnresolvedType on dangling target)
local_binding_for_item / build_type_env / build_type_env_unresolved alias guards
GREEN/RED witnesses + migration-debt baseline bump

Agree with APPROVE — v1 seed bridge via Node property discrimination, not a parallel fork of v2's AliasBindingRow.
