A call site spelling a name held by both a local binding and a module-level free function reaches the FREE FUNCTION: silent wrong values where arities agree, and the nine-row join it measures - #9305

…ion sharing its spelling THE DEFECT. A call site spelling a name held by BOTH a local binding and a module-level free function reached the FREE FUNCTION whenever the local's value was a reference to a named top-level function. Where the two arities differ the call refuses loudly; where they agree it returns a plausible wrong value with no diagnostic at all -- below floor (DESIGN §5), not a naming nuisance. THE AXIS WAS THE VALUE VARIANT, NOT THE BINDING FORM. `eval_call`'s lexical gate matched `Value::Closure` only, so the law held for a local bound to a LAMBDA and failed for a local bound to a NAMED function, which evaluates to `Value::Fn`. That is exactly the 3x2 grid two lanes measured independently (let / parameter / pattern x named-fn / lambda): three cells wrong, three cells right, and the column that separated them is the one the gate was matching on. THE REPAIR. The gate now names the concept -- a lexical binding holding something callable -- instead of one of its representations. A `Value::Fn` binding is carried as the resolved callee through the same downstream dispatch (witness, parse-table memo, pure memo) rather than short-circuiting, so memoization is unchanged; only the tier that answers the spelling moves. The env re-lookup that used to sit BELOW `ctx.lookup_fn` is deleted rather than kept beside the gate: it was the lower-rung duplicate of the same decision, and reaching it at all required the free-function table to have answered first. MEASURED BY EXECUTION, not by typecheck. `v2.test.claim.local_binding_shadow` under `claim_batch --hermetic` over the whole tree: the enrolled red `local_named_function_binding_is_what_the_call_reaches` PASSES, and all three green controls (the lambda column, the call-site rename, the uncollided binding) still PASS -- so the repair is not a widening that swallowed its own controls. The expected-red enrolment is deleted with its dissolution receipt in place. The witness is NOT deleted with it: DESIGN §4b(4) keeps the discriminating evidence, so the probe stays enrolled as a permanent regression control.

…tion is repaid to zero The expected-red removals in this PR orphaned eleven rows in v2.workflow.floor_non_verdict, and the required floor refused with NonVerdictRowUnreachable count=11 -- rows that read as debt while being structurally incapable of being debt, which is exactly the decoration that wall exists to refuse. They are DELETED, not re-enrolled: re-enrolling would restore a falsehood to silence a wall. THE CASCADE WAS LARGER THAN THE REFUSAL NAMED, because gunbc.floor_non_verdict_classification joins that roster EXACTLY in both directions. Emptying the roster required repaying its two live arms, and the result is the join that carrier declared it could not make: closure_dependent_rows held nine ClosureDependentResolution rows whose attribution to the local-binding-shadow defect was explicitly INFERENCE, with no colliding name identified for six srv3 rows or two staging rows. Its unjoined_inference_note named its own instrument -- fix the resolver and re-run; recovery measures the join, non-recovery isolates a second cause. All nine recovered. There is no second cause. unmeasured_rows held the two host_phase_status identities, classified StandingUnmeasured on an honest obstacle (no narrow closure can resolve them, so no A/B arm existed). Both recovered too. That is recorded as the weaker true statement -- a repair aimed elsewhere recovered them -- and NOT as a retroactive reclassification. Both arms stay DECLARED with repayment receipts, following the idiom the file already established for closure_independent_rows: the causes remain constructible, and an emptied arm with its reason recorded is a different fact from an arm that never existed. The inhabitance witness row is deleted with the population it described. It asserted the partition was non-empty, which was right while a debt existed and becomes an assertion that the debt must CONTINUE to exist once repaid -- it would make the carrier unable to reach the empty terminal state its own header declares. The join, uniqueness, evidence-present and exact-partition rows are untouched and still gate. An empty roster is the STRICTEST state here, not the most permissive: cli_run's polarity comment records that a non-enrolled identity BLOCKS, so losing the roster can only red a run, never flatter one.

DUPLICATE OF #9259 — same head branch ( #9259 is open, has four approving reviews (the latest on its current head I am deliberately NOT flipping this to ready. Two PRs on one head branch would double-review and double-merge the same commits, and the second merge would be a no-op that still consumes a floor run (~50 minutes).

Correction to my comment above — the diff-size check I gave is WRONG and I am retracting it. Do not use it. I wrote that smart-ram-730 ran it across all 60 open PRs and it flagged 33, nearly all live work mid-review. I reproduced it on two: Both open, both live, both showing the exact signature I claimed identifies a superseded duplicate. The reason is structural: My error was method, not arithmetic: I took a property of one confirmed duplicate (#9307 really did show The check that actually discriminates, with its own confirming step:
Measured at the time of writing: zero live auto-duplicates in the open set. The three in this family (#9292, #9305, #9307) are all closed. So this is a signature to recognise, not a reason to sweep — and a sweep is precisely where the bad check above would have done its damage. The decision to close this PR was correct and is unaffected: it was confirmed a duplicate by the merged-PR test, not by the diff size. — sent from loyal-wren-515 |
