§5 de-fork activation arbiter: grounded cross-tree admission witness (host-tagged ingest, no explicit MoreFundamental) - #5506
Merged
Conversation
…n from host tags The remaining activation gate: prove by execution that the source_root carrier (#5473/#5486) is CONSUMED on the real grounded compile path, not merely carried. Feeds a host-tagged SourceRootIngest through the real machinery — program_assembly_fold_ingest builds the QualifiedName->SourceRootRef index, source_root_set_from_ingest builds the active-root set — then runs cross_tree_edge_decision (the exact fn admit_import_entry calls). Nothing about fundamentality is supplied; MoreFundamental/LessFundamental is derived by tree_fundamentality_order. By execution (gunbc run --claim-run): - v2-subject (V2Tree) -> dsl-target (DslTree) => EdgeCrossAdmitted (true) - tags reversed: dsl-subject -> v2-target => EdgeCrossDenied (true) Asserts the exact decision variant (not a Bool proxy) so the RED leg cannot pass for a wrong reason. Flip either source_root tag and the witness goes the wrong way (discriminating oracle). Verdict: cross-tree import is ACTIVE on current main, grounded on filesystem-truth source-root tags — the de-fork collapse fan-out is unblocked. Floor-auto-enrolled via _test.dag naming.

…-forks + 7 grounding cluster) (#5511) * §5 de-fork audit: re-verdict census by execution — 2 mirrors + 2 not-a-forks + 7 grounding cluster The dsl↔v2 std fork is not "mostly temp v2 mirrors": by-execution decl-set comm + shared-type-body diff shows 2 true mirrors (reducible/measure), 2 pure name-collisions (coercion/node), and 7 divergent groundings (algebra/logic/nat/ integer/float/effects/verification) — the same concept grounded on a different axis/realization per tree (e.g. EffectShape: operation-axis in dsl vs idempotency-class in v2; TestClaim simple-proposition vs grounded coproduct). The grounding cluster is a single-authority unification DESIGN downstream of the numeric tower (#5428) + model↔realization grounding, not a mechanical repoint. Also: §1 updated — cross-tree import is ACTIVATED (#5473/#5486 grounded, #5506 arbiter witness proves it live, #5504 fixed the abs-vs-rel admission bug); the former "wired but off" blocker is dissolved. Structured §2 as operator decision-input per concept (shared / shared-body-divergence / each-side-unique / grounding-entanglement). DESIGN §6: a stale doc contradicting ground-truth is parallel-representation debt. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * §5 audit: correct node/coercion to v1-artifact category (DEFER to v1-shrink) verify-before-act caught a scoping error: importer greps omitted src/v1, and src/v1 is a live consumer of dsl/std. node + coercion renames are NOT clean-lane — both cascade into the v1 seed (04_infer inference stage import + emitted Rust std_{node,coercion}.rs + a guard test). Per bright-stag's ruling, DEFER both to v1-shrink: on v1-delete node self-dissolves (dead file → delete, no rename) and coercion shrinks to a v1-free disambiguation (4 extdeps + v2). Census now has THREE categories: (a) 2 true mirrors, (b) 7 grounding divergences, (c) 2 v1-artifact collisions. Recorded the dissolution trigger.

What
The §5 de-fork activation arbiter: a by-execution witness proving cross-tree import is LIVE on the real grounded compile path, derived from filesystem-truth
source_roottags — the gate that unblocks the de-fork collapse fan-out.Why
#5473 + #5486 landed the grounded
source_rootcarrier onDagSourceReadWitness+ the grounded tree-pair relation (tree_fundamentality_order). The existingname_resolve_cross_tree_resolution_testprovesresolve_with_admission_groundedadmits v2→dsl given a hand-built index. The unproven leg was whether the carrier is actually consumed end-to-end: host tags → program-built index → grounded decision. "Structurally wired != proven until it runs green."How (the real machinery, nothing supplied)
Feeds a host-tagged
SourceRootIngestthrough:program_assembly_fold_ingest→ builds theQualifiedName → SourceRootRefindex from each read'ssource_roottag,source_root_set_from_ingest→ builds the active source-root set from the same tags,cross_tree_edge_decision→ the exact fnadmit_import_entrycalls.No explicit
MoreFundamentalanywhere — it is derived bytree_fundamentality_order. (That is the illusion the audit doc names: the explicit-supply test only passes because it hands the order in.)Verdict (by execution,
gunbc run --claim-run)Asserts the exact decision variant (not a Bool proxy), so the RED leg cannot pass for a wrong reason. Flip either
