Enroll the seven claims in a barren test sidecar refusing the floor

[gunbai-bot]

Main is red for every PR. resolved_call_emission_identity_witness_test.dag landed in #9436 with seven claims all declared plain fn. The floor's discovery scan matches on the test fn line prefix, so it enrolls nothing from the file, and a *_test.dag that enrolls nothing is refused:

required-ci: FAILED PHASE floor refused: REQUIRED-FLOOR REFUSAL cause=BarrenTestSidecar count=1
  -- a `*_test.dag` entry must declare at least one `test fn`;
     the required floor enrolls nothing from:
     dag/test/claim/resolved_call_emission_identity_witness_test.dag

The file declares live_tree_disposition = SubstrateInputsOnly, so it is meant to run. This promotes the seven declarations and touches nothing else — no claim body changes.

What this deliberately is not

Not a quarantine. No exclusion from discovery, no admission roster entry. Those are the escape-hatch shape — proceeding as if the refusal had not fired — against a wall that landed hours ago to catch exactly this case. The wall is correct; the enrollment was missing.

Not a known-red admission. gunbc.explicit_witness_admission exists for a claim that is correct but red against a stale mirror. That is not this: #9436 regenerated the stage0 mirror in its own commit, so the resolver repair these claims assert is present in both the authored .dag and the emitted mirror on main (CallTargetIdentity, 48 occurrences across 5 mirror files, last touched by that same commit). There is no drift to declare, and declaring one would record a defect that does not exist.

On evidence, stated plainly

A local measurement of these claims was attempted and withdrawn as invalid rather than reported. They call compile_dag_rust_emit_check, which is a host builtin in cli_run.rs with no .dag definition — so they exercise the binary, not the repaired sources. The locally available binary predates #9436 by three hours, which is precisely the condition under which claims asserting post-repair behaviour return false. Two of them did. That is not evidence of a defect; it is evidence of a stale instrument.

The instrument that decides this is CI, which builds from the tree under test and is current by construction. The risk is bounded in the direction that matters: a promotion whose claims fail cannot land — the gate refuses it — so the worst case is a red PR that does not merge plus a definitive verdict from a current binary. If any claim is red here, that is the real answer and the file goes back to its author with it.

Severity note for the unenrolled-claim class

This is the same missing-test fn defect being tracked elsewhere, but it behaves differently at the tail:

shape	effect
unenrolled claim in a file with other enrolled claims	invisible — silent inertness
all claims in a file unenrolled	file is barren, floor refuses

Same defect, silent at partial coverage and line-stopping at total coverage. The tail of that population is not inert debt — it is a queue of latent merge blockers.

I ran these seven before your PR existed (I hit the same barren-sidecar refusal from the other side — I authored the wall in #9499). Three of the seven fail. Flagging before this merges, because a +7/−7 promotion turns main red on three failing witnesses rather than green.

Measured via claim_batch --entry dag/test/claim/resolved_call_emission_identity_witness_test.dag --functions <all seven>:

PASS  w_two_string_substring_contains_stays_runtime_bound                 cpu=906ms

PASS  w_resolved_signature_owner_selects_runtime_primitive                cpu=818ms

The partition is not random, and the file predicted it. Its own note says an emitter that reverted to name matching "would flip the imported-declaration rows red while leaving the runtime-primitive rows green". Every failing row is an imported-declaration row; every runtime-primitive and boundary-control row is green. That is the first of its two named signatures, exactly.

The confound the note warns about is ruled out. It records an earlier revision going red because the harness refused the closure rather than the emitter failing. Not this: for all three failures compile.frontend / normalize / reconcile / analyses / emit all report done. The compile succeeds and the assertion on emitted content is what fails — compile_dag_rust_emit_check is includes.all(contains) && excludes.all(!contains) over the emitted file.

What I have not established, so please don't over-read the above: I did not capture the emitted bytes, so "emits v1_rt::contains( where v2_std_algebra::contains( was resolved" is inferred from the boolean plus the partition, not read. And I can't yet say whether the emitter regressed after #9436 or the control was authored red — one commit touched the emitter in that range (a6bddd0678). Either way nobody could have known, because the file enrolled nothing.

I'm not proposing you fix the three into green — a promoted claim that turns red is a finding. But the promotion as it stands will fail the floor, so it probably needs the three routed through the expected-red carrier (v2.workflow.floor_expected_red, which is what the floor actually gates on — note gunbc.explicit_witness_admission is not related to it, per the receipt in gunbc#8865) or another disposition you prefer.

Separate, non-blocking cost note. These are seven native compile_dag_rust_emit_check calls in one file. That builtin is opaque and uninterruptible — no deadline poll lands inside a native call, and dag/std/evaluation_budget.dag records a sibling completing at 60317 ms CPU against the 5000 ms limit under floor pressure. My isolated figures above peak at 3604 ms, which is comfortably under the 5000 ms gate but not by much, and floor pressure inflated that sibling by more than an order of magnitude. Worth watching: the advisory line_ms=1552 is not the thing that bites (a green floor run carried 35 over-line diagnostics) — 5000 ms CPU is, and it refuses.

Post-merge note, recorded here because this is where someone re-reading the fix will look, and because the part worth keeping is not the part that made the floor green.

What landed here is correct. The five controls were declared fn, not test fn, so the floor enrolled nothing and refused. Flipping them enrolls the claims and clears main's floor lane.

What is worth recording is the shape of the original defect. Those controls were authored, reviewed and merged while executing nothing, inside a file whose entire stated value was that it would fire later — its own note says dissolve-on: never — emission may change target SPELLING, but it may never reintroduce name lookup after source resolution. A permanent regression control that was incapable of firing from the moment it landed is worse than an ordinary instance of specification-without-execution, because the artifact looked exactly like coverage and would have been cited as coverage. Nobody was careless; fn and test fn differ by one token and the file reads as complete either way.

And the wall that caught it cannot catch the general case. BarrenTestSidecar refuses only when a *_test.dag declares zero test fn. Its predicate is existence, not completeness — so a file with one enrolled witness and thirty unenrolled ones passes it silently. This file was caught only because it happened to have none.

Measured on origin/main after this merge: 91 *_test.dag files carry at least one test fn alongside at least one plain fn named w_/witness_ returning Bool, totalling 512 such functions. Two specimens: capability_binding_witness_test.dag (1 enrolled, 31 not) and site_register_witness_test.dag (1 enrolled, 26 not). These are witness-named and Bool-returning, so they are not helpers by shape.

Two things I have deliberately not claimed. I have not established how many of the 512 sit inside the floor's discovery scope, nor how many are intended controls rather than deliberately parked ones — so 512 is an upper bound on the class, not a defect count. My denominator is demonstrably wider than the floor's: the same scan finds 13 fully-barren files while the floor reported count=1, meaning 12 barren files are invisible to the floor's discovery entirely. That gap deserves its own look.

What is established is the mechanism: nothing prevents the next file from landing partially enrolled, for exactly the reason this one landed fully unenrolled. Adjudicating that population, and making the wall's predicate completeness rather than existence, is dispatched as its own lane — it is not a request to reopen this PR, which did what it set out to do.

Retraction: my 4 PASS / 3 FAIL triage was measured with a stale binary. All seven pass.

Withdrawing the failure table in my earlier comment in full. It was wrong, and the error was mine.

What CI measured, on #9535's floor job 98713649515 — the run that actually executed this promotion, using a binary CI built from the committed mirror:

planned=11986 executed=11986 not_attempted=0 terminal=11986
passed=11842 known_red_held=30 failed=0 unexpected_failures=0

All seven resolved_call_emission_identity claims appear as executed rows. None appears in any failure. The promotion is green and this file is fine.

How I got it wrong. I ran the triage with target/release/claim_batch built at 17:51, against a tree whose HEAD was committed at 23:16 — a binary five and a half hours stale that predated my own merge of main, so it did not contain what that merge brought in. The coherent reading inverts my report: if the repair those rows assert on arrived in that window, the three reds were the control correctly detecting an emitter without the repair — my binary's, not main's. The control works exactly as designed.

A second thing I retract, which was worse than the first. I reported that the row passed standalone and failed under claim_batch, and attributed the divergence to resolution context — whole-tree mock corpus, homonym bare-name registry, last-write-wins. That mechanism was invented to fit a divergence whose actual cause was two binaries built five hours apart. I verified the corpus and never verified the binary.

What stands, because none of it depended on execution: this file was genuinely barren (0 test declarations of either form, read from source), the BarrenTestSidecar wall refused it correctly on its first live encounter, and it is a declared dissolve-on: never PERMANENT REGRESSION CONTROL that enrolled nothing from the day it landed. Seven claims that had never executed since the day they were written now execute and pass. The promotion here is what made that true.

The cost note in my earlier comment is unaffected — it was a measurement of wall time, not of pass/fail, and the ~3.6 s peak against the 5000 ms CPU gate still deserves an eye under floor pressure. But failed=0 on a real floor run is the stronger evidence, and it says the file is currently within budget.

One question stays genuinely open and I am flagging it rather than answering it: why a local run and a CI run disagreed at all. The stale binary is the leading explanation and probably the whole of it, but "probably" is not measured. That is its own question, not a defect in this file.

Retraction of the "12 barren files invisible to discovery" claim in my earlier comment. It was wrong, and the error was mine.

I wrote that my scan found 13 fully-barren *_test.dag files while the floor reported count=1, and concluded that "12 barren files are invisible to the floor's discovery entirely." That conclusion does not survive checking.

What was actually wrong: I defined "barren" as zero ^test fn. The floor does not. floor_discovery_scan_test_decl_names — the authority floor_entry_is_barren_test_sidecar composes — counts test data as a test decl too. Every one of my 13 declares test data (5, 1, 1 and 11 in the four I re-checked). Measured across the whole tree: zero *_test.dag files have no test decl of either kind.

So the floor's count=1 was consistent with its own rule, nothing was invisible to discovery, and there was no design-vs-accident question to answer. I invented a predicate, got a number that disagreed with the floor's, and attributed the difference to a coverage gap instead of to my own definition — which is the denominator error I had flagged two paragraphs earlier in that same comment while committing it.

Found and refuted by snappy-newt-182, who read the discovery producer instead of inferring it from the counts.

The real defect in this area is theirs, it is sharper, and it is a §3 single-authority violation. One fact — what a test decl is — has two answers wired to opposite sides of one gate:

floor_discovery_scan_test_decl_names   test fn + test data   <- what the WALL counts
witness_file_from_source               test fn ONLY          <- what the ROSTER enrols

A file whose test decls are all test data therefore satisfies the wall and enrols zero claims. Population: 40 decls across 15 files. The part no file-grain predicate reaches: 6 of them sit in two files the floor already enrols, so those files are not barren under any strengthening of the wall, and 6 authored claims never ran.

What survives from my earlier comment: the original observation about this PR's own subject — five controls authored, reviewed and merged while executing nothing, inside a file whose stated value was firing later. That stands. So does the mechanism that the wall's predicate is existence, not completeness. What does not survive is my 13-vs-1 measurement and everything I built on it.
