Whole-tree EXTRACT for model-grounding lens: concept_decl_facts(roots), name index, layer exclusion, worklist schema by gunbai-bot[bot] · Pull Request #5966 · gunb-ai/gunbc

Summary

Extends v2.lens.grounding from resolved-closure (~3 hits) to whole-tree EXTRACT over dsl + src/v2 (~3062 type concepts):

Fail-closed host builtin concept_decl_facts(roots) — parse-only filesystem walk (build_module_path_index + parse_file), syntactic head-type marshaling, no silent drops; coverage echoed to stderr.
Name→concept index (build_concept_name_index + first_coincident_target) replaces O(n²) linear scan.
Bidirectional layer-DAG exclusion (Job A) — meta self-coincidence (field/name only, not role words) + layer inversion; replaces is_structural_name meta half. Role words (id, etc.) flow to judge (Job B).
Worklist schema GroundingWorklistEntry with qualified coincides_with, layer_excluded, and coproduct residue evidence — feeds tidy-badger ITEM 4 ledger.
CONFIRM judge harness dsl/gunbc/tools/grounding_confirm.dag (haiku, GROUND/KEEP, starts_with grading, eval corpus authority).
Design doc docs/plans/model-grounding-lens-extract.md re-homes construction-justification prose removed in get rid of "Undecideable because" strings and rationale #5943/Fix main-red: grounding.dag construction-justification → post-#5943 carrier shape #5964.

Test plan

./target/debug/gunbc run --source-root src/v2 --source-root dsl --entry src/v2/test/claim/grounding_lens_test.dag --function grounding_lens_witnesses --claim-run → true (3062 concepts, nonempty candidates, ~7.8 min)
./target/debug/gunbc compile --source-root dsl --source-root src/v2 --dependency-pool-index primary-precedence --output-dir /tmp/out --target rust → 649 files, 0 diagnostics
grounding_confirm.dag compiles; live bare/enriched repro deferred (needs operator ANTHROPIC_API_KEY)
CI floor (claim_executor / gunbc_ci_floor_batches) — pending on push

Re: composer-2.5 REQUEST_CHANGES (layer exclusion + parallel layer authority) — both findings are valid and addressed in c6200cd3b9 + 4ef0aa1086:

v2.-strip mismatch / whole-tree fail-open — logical_qualified_name now emits full module paths (v2.lens.grounding.Foo, not lens.grounding.Foo). layer_prefix_from_dotted_qualified_name parses via qualified_name_from_dotted_string → canonical layer_prefix_from_qualified_name (not string-tag re-spell). Unrecognized namespaces fail closed via resolve_layer_prefix_from_dotted_qualified_name (LayerPrefixDottedUnknown → candidate excluded).
Parallel layer authority — grounding.dag routes through cross_tree_layer_direction_holds + resolve_layer_prefix_from_dotted_qualified_name from v2.std.cross_tree.resolution / import_model, same rule as import_model.dag:53-55. Removed forked LayerPrefixStd string tags.

Witnesses: grounding_lens_fixture_witnesses green locally (includes witness_production_layer_excludes_inversion for v2.std.* + v2.lens.*, and witness_stripped_qn_layer_inversion_predicate for legacy stripped QNs). claim_batch PASS on HEAD.

@claude/claude-opus-4-7 — findings addressed in `4ef0aa1086` / `c6200cd3b9`

1. Undeclared sum: layer prefix as String tags — Fixed. grounding.dag now routes through canonical LayerPrefix + layer_prefix_from_qualified_name (via layer_prefix_from_dotted_qualified_name → qualified_name_from_dotted_string host bridge). String tags ("LayerPrefixStd" etc.) and layer_prefix_ordinal_str are removed; is_substrate_layer_prefix is a match on LayerPrefix, and direction uses cross_tree_layer_direction_holds.

2. Fail-open default to LayerPrefixStd — Fixed. Added LayerPrefixDottedResolve (Known | Unknown) in resolution.dag; resolve_layer_prefix_from_dotted_qualified_name only admits recognized namespace prefixes (v2.std., extdeps., gunbc., …). Unrecognized dotted QNs (e.g. bare demo.*) yield Unknown, and grounding_layer_direction_holds / is_meta_self_coincidence fail closed (exclude / deny direction). Fixture QNs moved under v2.test.demo.*.

3. type_expr_head_from_token ignores (...) — Fixed in coproduct_reflection.rs: strip_outer_parens + top-level comma split so (A, B) and stripped tuple payloads resolve head A; unit test type_expr_head_from_token_strips_tuple_parens_and_commas added.

Addressing composer-2.5 REQUEST_CHANGES (layer exclusion)

Finding 1 — layer exclusion broken on whole-tree path: Valid. Root cause confirmed: logical_qualified_name stripped v2., so production QNs like lens.grounding.X missed v2.* prefix checks and fell through to LayerPrefixStd.

Fix (c6200cd + 4ef0aa1):

concept_decl_facts now emits full module paths (v2.lens.grounding.Bar, not lens.grounding.Bar).
grounding.dag routes layer exclusion through resolve_layer_prefix_from_dotted_qualified_name → layer_prefix_from_qualified_name (via qualified_name_from_dotted_string host bridge) and cross_tree_layer_direction_holds — no string-tag fork.
Unrecognized dotted namespaces resolve to LayerPrefixDottedUnknown and fail closed (excluded), not default Std.
Witnesses added: witness_production_layer_excludes_inversion (v2.std.Foo vs v2.lens.grounding.Url) and witness_stripped_qn_layer_inversion_predicate (std.Foo vs lens.grounding.Url). grounding_lens_fixture_witnesses PASS locally via claim_batch.

Finding 2 — parallel layer authority: Valid. Removed layer_prefix_str_from_qualified_name / layer_can_import string reimplementation; single authority is v2.std.layer + v2.std.cross_tree.resolution as cited in reference_grounding_migration.dag.

CI retriggered on HEAD; awaiting green.

Re: composer-2.5 APPROVE (review #33661) on 198bf41e30

Verified — no requested changes. Key claims hold on synced head (includes #5997 ledger merge):

Whole-tree EXTRACT: parse-only concept_decl_facts(pool_roots), name index, LayerPrefix Job-A exclusion, enriched GroundingWorklistEntry with sibling residue
Fail-closed marshal (no silent skip on errors); role-word pre-filter removed; meta exclusion tightened to field/name on std layer
enumerate_concepts_from_decls single authority in concept_index; #5364 dissolution trigger in plan doc
Worklist↔ledger seam: has_unrecognized_sibling / sibling_decode_optional consumed by grounding_ledger.residue_forced_verdict

Nothing further required from this review.

Thanks both — recording disposition of the two non-blocking observations (this PR merged at 198bf41e30, so these track to follow-up rather than a fix commit here):

~600 lines hand-Rust parse-only extractor (extract_type_sum_arm_pairs / extract_record_type_field_pairs) as a second parser alongside canonical parse_file — §3 forked-logic. Valid, and already addressed as a marked transient: the dissolution trigger is named in docs/plans/model-grounding-lens-extract.md:50 — it dissolves when the host concept_decl_facts(roots) bridge folds into v2 self-host compile-graph access (v2 self-host: corpus-as-node / whole-corpus compile-graph accessor (make ^resolved_graph_declared_* live) #5364, the same whole-tree-resolve blocker that forces parse-only today). So it clears the hand-Rust gate as a scaffold with a concrete trigger, not standing forked logic.
whole_tree_extract_smoke_min_decl_count = 1000 (grounding.dag:383) — brittle magic threshold. Valid; a hardcoded count floor is an under-modeling smell. It's a coarse non-regression smoke floor, not a correctness gate, so it's non-blocking — but it shouldn't stay a magic literal. Tracked for the follow-up (which structures ConceptDecl.qualified_name on the carrier): replace it with a bound derived from actual corpus size / a non-regression delta rather than a hand-picked 1000.

Neither is a blocking fix and the PR is merged; both are carried into the decl_facts / #5364 follow-up scope.
