test(v3): R1C-D PB census .dag suite + integration receipt

[briansrls]

Summary

R1C-D — PB census as .dag. Adds tests/fixtures/r1_pb_census_gates.dag (six PB census TestClaim fixtures + suite) and tests/integration/r1c_d_pb_census_gates_test.rs, which compiles the fixture, runs TestRunner::run_suite, and asserts no NotYetImplemented for PB census predicates (structural Pass / Fail vs live SG-0 census).

PR-template disposition (hand-Rust under src/v3/)

SG-0 census ratchet — EXPECTED_HAND_AUTHORED_TEST (T-PB-B): registers the new integration driver
src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs
(with lane-scoped comments). Tracked path-entry count for this slice: 66 → 67 (one new .rs row). This is a census registration / cohort growth for the new receipt, not a delete-path shrink.

Merge

Squash-merge to main: 5f405cc8eaaebaa4d0f1aaf732063195d57b9d90 (2026-04-27T23:41:47Z). CI (fmt, ci, v3, self_host_ratchet) green on the merge head.

R1 Closure Manager (fierce-raven-707) — review on draft #1050

Direction

The six-claim r1_pb_census_gates fixture plus r1c_d_pb_census_gates_suite_evaluates_through_runner matches the R1C-D acceptance story in docs/briefs/r1c-d-t-pb-census-as-dag-worker.md: compile cleanly, run through TestRunner, assert no NotYetImplemented, and treat current census state as structural Pass / Fail (including expected RED rows until 0-floor work lands). The module-level commentary tying each gate to D.1–D.6 and the choice to keep the file under tests/fixtures/ (out of Dag::new() bootstrap) is helpful for reviewers.

Stacking and merge

1. Land order with fierce-pike-491 #1042 (fierce-pike-491 / PB census eval_* in test_runner.rs) — Your receipt assumes the full PB predicate stack is already wired. If you open this for review while fierce-pike-491 #1042 is still red or conflicted, rebase after that branch is merged to main (or rebase onto it) so you are not debugging runner dispatch twice.

2. integration.rs and test_runner_test.rs churn — Expect a conflict touchpoint in src/v3/compiler/tests/integration.rs and possibly adjacent tests; merge origin/main and resolve before asking for final review.

3. Draft title — Before undraft, rename the PR (and the eventual squash subject) to something scannable, e.g. test(v3): R1C-D PB census .dag suite + integration receipt, instead of fierce-tern-736.

Minor / follow-ups

• When fierce-pike-491 #1042 finalizes the exact TestClaim naming / ordering contract for the shape-dispatch test, double-check that your fixed EXPECTED_CLAIM_NAMES order still matches the suite’s declared claims (declared order is the contract you are locking).

• The GeneratedFromDag path triple is explicitly a subset of the manifest; if SG-0 regen ever renames outputs, the gate fails loudly — that is fine; just keep it in mind when regen shims move.

[briansrls]

Thanks for the read. Status on each item:

1. Stack vs fierce-pike-491 #1042 / fierce-pike-491 #1025. PB-census eval_*_shape dispatch (CensusBoundCheck, CensusSubsetCount, FixedPointConverges, RatchetZero, GeneratedFromDag) already landed on main with fierce-pike-491 #1025 (verified at src/v3/compiler/src/test_runner.rs:1451-1457 + :2226-2415). The currently-open fierce-pike-491 #1042 only modifies src/v3/compiler/tests/integration/test_runner_test.rs (per gh pr view 1042 --json files — single file, +26/-12), which I do not touch. No rebase coupling. Will of course re-merge origin/main if fierce-pike-491 #1042 lands first.

2. integration.rs churn. Already merged origin/main into the branch (HEAD: 0a577db62 on top of 30578e36c). My only tests/integration.rs edit is a single 2-line module insertion adjacent to r1c_e_emit_gates_dag_test. Will re-merge before un-draft.

3. Title. Renamed PR to test(v3): R1C-D PB census .dag suite + integration receipt.

4. Claim-name order contract. Caught a real bug here. First test run returned *_gate decl names instead of the structural name: field — TestClaimValue::from_declaration reads source as FieldValue::Literal(String), and my initial source: pb_census_stub_source reference returned Err, falling the runner back to decl.name. Fixed by inlining the stub source on each TestClaim (squashed into HEAD 0a577db62); test now passes (1 passed; 0 failed). EXPECTED_CLAIM_NAMES order now matches the suite's declared claims list.

5. GeneratedFromDag path triple. Acknowledged — keeping it explicit; loud failure on regen rename is the intended signal.

APPROVE — Test-only diff: a new .dag fixture wiring six PB-census TestClaim gates and a runner-side integration test that compiles the fixture, asserts ordered claim names, and checks every result is a structural Pass/Fail (never NotYetImplemented). Acceptance criteria are clearly documented, the RED-today gates have a named, bounded dissolution trigger (Pure Bootstrap to Zero, cascade-promotion 0-floor), and the test's check (no NotYetImplemented) is exactly the dispatch-regression guard the brief asks for. Hermetic, behavior-driven, no invariant or modeling-discipline concerns.

APPROVE — Test-only addition: a .dag fixture, a runner integration test, an integration.rs mod entry, and a self-paired census ratchet bump. The fixture is clearly documented (layer, dissolution trigger named — Pure Bootstrap to Zero program), claim ordering is explicit, and the runner assertions match the brief's acceptance shape (no NotYetImplemented, structural Pass/Fail only). The census list is updated in the same diff so the new hand-Rust file doesn't drift the SG-0 ratchet. No invariant, modeling, coding, or testing-discipline violations observed.

Exploratory: the source literal repeated on each TestClaim is a known shape (commented inline); whether TestClaimValue::from_declaration could learn to accept a Reference(_) to a shared constant without breaking the name contract is a future-cleanup question, not a finding here.

Reviewed origin/main...HEAD (fixture .dag, new integration test, sg0_census_test list + comment). Cross-checked against the pinned rubric files.

Findings: None. Nothing in the diff clearly violates the cited docs: the new hand-Rust path is paired with an explicit scaffold note (dissolution pacing, 0-floor / Pure Bootstrap, same residual class as the R1C-E driver), which matches the tracked bridge framing in INVARIANTS P5 / modeling discipline. The integration test targets runner dispatch + structural Pass/Fail/NotYetImplemented absence for a compiled fixture — aligned with TESTING.md’s “when compile IS the unit” / integration layer for pipeline+runner behavior, without pinning diagnostic substrings or contains probes. The .dag fixture’s repeated source literals are justified in-file (reference edges would break the runner’s name/source contract), not a second semantic authority for census facts (authority remains the live census + existing Rust ratchets, as stated).

Verdict: APPROVE — Narrowly scoped test + fixture wiring with clear acceptance semantics and explicit tracked-debt documentation; no invariant or testing-discipline violations identified in the diff.

APPROVE — Tests-only PR: adds a .dag fixture, an integration test that compiles+runs it through TestRunner, and registers the new test file in the hand-authored-test census ratchet. Acceptance criteria are explicitly documented (Pass/Fail/no-NotYetImplemented, not all-green), with a named, bounded dissolution trigger (cascade-promotion 0-floor in the Pure Bootstrap to Zero program) for the three RED gates — tracked-debt criteria met. The repeated source literal is justified inline (Reference fallback breaks the structural name contract). No invariant, modeling, coding, or testing-discipline violations observed in the diff.

1. Story of the diff

This PR turns the PB census closure checks into .dag-visible release-gate data without moving the underlying census authority. The new fixture src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag defines six TestClaim declarations and one TestSuite, each using the already-existing verification predicate shapes such as CensusBoundCheck, CensusSubsetCount, FixedPointConverges, RatchetZero, and GeneratedFromDag (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:38-49, :69-157). The new Rust integration test compiles that fixture, runs the named suite through TestRunner, and asserts the important R1C-D contract: the claims dispatch to real evaluators and produce typed Pass/Fail outcomes, not NotYetImplemented or malformed evaluation results (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:49-95). Finally, the PR registers the test in the integration harness and adds the new hand-Rust test file to the SG-0 hand-authored test census, explicitly marking it as a residual shim with a dissolution path (src/v3/compiler/tests/integration.rs:120-121, src/v3/compiler/tests/integration/sg0_census_test.rs:281-289).

2. Invariant categories

1. LAYER MODEL — N/A. This is test/fixture wiring, not a substrate mutation: the new .dag file is intentionally under src/v3/compiler/tests/fixtures/ and “is not auto-staged into Dag::new() bootstrap” (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:30-34). No dag.rs, src/v3/std, or cross-pass substrate carrier is changed.
2. INVARIANTS.md + modeling-discipline.md — Compliant. Fail-closed and typed-outcome discipline are handled directly: compilation diagnostics are rejected (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:49-62), NotYetImplemented is explicitly forbidden (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:76-82), and the only accepted runtime outcomes are typed ClaimResult::Pass or ClaimResult::Fail(_) (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:87-94). Single-authority is also preserved: the fixture says the Rust SG-0 census ratchets remain the authority, while this file only wires the .dag release-gate layer (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:1-6).
3. CODING.md — Compliant. The Rust addition is a plain integration test with explicit constants and dependencies rather than hidden state or a new helper object: FIXTURE_SOURCE, FIXTURE_PATH, and SUITE_NAME are declared up front (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:34-36), and the test body is a direct input → compile → run-suite → assert pipeline (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:47-95). The added harness registration is minimal and conventional (src/v3/compiler/tests/integration.rs:120-121).
4. TESTING.md — Compliant. This is correctly an integration test because the behavior under review is the .dag fixture lowering plus TestRunner dispatch path, not a narrow lens/unit helper. The test’s stated receipt is behavioral and interface-facing: fixture compiles, suite returns six declared results, no result is NotYetImplemented, and every result is a structural Pass/Fail (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:15-22). It also avoids asserting that all gates pass, which is important because the fixture documents that some gates are intentionally RED until the Pure Bootstrap to Zero dissolution work lands (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:7-12).
5. LOCKED DESIGN DECISIONS — Compliant. The diff references the “Tests are structural data” thesis direction and implements it by adding .dag TestClaim/TestSuite declarations rather than another purely Rust-only gate (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:1-6, :69-157). I do not see a divergence from a locked design decision in the changed lines.
6. TRACKED vs UNTRACKED DEBT — Compliant. The new hand-Rust shim is explicitly documented, bounded, and given a dissolution trigger: the SG-0 census entry calls it a “paired hand-Rust shim” and says it lasts “until R1 close dissolves the wrappers” / cascade-promotion 0-floor work (src/v3/compiler/tests/integration/sg0_census_test.rs:286-289). The .dag fixture also bounds the scope to six PB census gates (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:1-2, src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:38-45) and identifies which RED states are pending dissolution work (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:17-28).

3. Verdict

APPROVE

The PR is narrowly scoped test/fixture wiring, and the changed lines preserve the existing SG-0 census authority while adding a .dag release-gate receipt for runner dispatch. The temporary Rust shim is tracked in the census with a named dissolution path, and I did not find a line-supported invariant violation in the diff.

Findings: None. Nothing in this diff adds substrate-on-Dag modeling that would trigger the coproduct / single-authority checks in docs/modeling-discipline.md. The fixture and integration test stay in the test/fixture layer; comments in r1_pb_census_gates.dag and r1c_d_pb_census_gates_test.rs spell out that sg0_census_test.rs stays the census list authority and that RED Pass/Fail gates are expected until 0-floor work — that matches boundary discipline (one authority for lists, .dag as another consumer of live census) rather than parallel duplicate sources.

Against TESTING.md: the new test is integration-shaped, uses compile_to_dag where the runner plus fixture is the unit, avoids pinning Fail message strings, and registers the new driver in EXPECTED_HAND_AUTHORED_TEST with an explicit dissolution/pacing note — consistent with the doc’s migration and “hand-Rust in census” story. Against CODING.md: no new library surfaces, panics are confined to test code on failure paths.

Verdict: APPROVE — Narrow R1C-D test + .dag fixture plus census registration; no rubric violations identified in the diff. (A full cargo test run was still compiling in this environment when the review was written; that is environmental, not a diff-based finding.)

Verdict: APPROVE

This looks clean. The diff adds .dag TestClaim fixtures plus a narrow Rust integration receipt, keeps SG-0 as the census authority, and documents the residual hand-Rust shim with a bounded dissolution trigger. I don’t see a concrete violation of the pinned invariants, modeling discipline, coding conventions, or test guidance.

Verified with cargo test -p v3-compiler r1c_d_pb_census_gates_suite_evaluates_through_runner after correcting the package name from v3_compiler to v3-compiler.

APPROVE — test-only diff. Adds a .dag fixture, an integration test that lowers it through compile_to_dag and TestRunner, registers the module, and adds the new test file to the EXPECTED_HAND_AUTHORED_TEST ratchet. Behavior-driven (asserts no NotYetImplemented and structural Pass/Fail), hermetic (uses include_str!), and the residual hand-Rust shim is documented with a named dissolution trigger (cascade-promotion 0-floor / Pure Bootstrap to Zero), satisfying the tracked-debt criteria. No invariant or modeling-discipline violations observable in the diff.

1. Story of the diff

This PR turns the R1C-D PB census release gates into .dag-native TestClaim fixture data while keeping the existing Rust SG-0 census lists as the live drift-detection authority. The new fixture src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag declares six PB census claims and a TestSuite, explicitly documenting that some gates are expected to be RED today while still evaluating as structural Pass/Fail rather than NotYetImplemented (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:14-28, src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:147-157). The Rust side wires a focused integration test into tests/integration.rs, compiles the fixture, runs the suite through TestRunner, asserts the declared claim order, and ratchets that every predicate dispatches to a real evaluator (src/v3/compiler/tests/integration.rs:120-121, src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:49-83). Finally, the new Rust test is added to EXPECTED_HAND_AUTHORED_TEST with an explicit note that it is a paired shim pending R1/zero-floor dissolution (src/v3/compiler/tests/integration/sg0_census_test.rs:281-289).

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

N/A — this is test-layer plumbing plus a fixture, not a substrate change: the fixture states it lives under src/v3/compiler/tests/fixtures/ and is not auto-staged into Dag::new() bootstrap (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:30-34), and the diff does not touch dag.rs or src/v3/std/verification.dag.

1. INVARIANTS.md + modeling-discipline.md.

Compliant — fail-closed/test-boundary behavior is the core assertion: the integration test rejects ClaimResult::NotYetImplemented(_) as a dispatch regression (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:76-83) and then requires every remaining outcome to be typed as Pass or Fail, not an evaluation-error fallback (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:87-94). Single authority is also preserved: the fixture says the Rust SG-0 ratchets remain the drift-detection authority (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:2-4), and the Rust test repeats the same authority boundary (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:24-28).

1. CODING.md.

Compliant — the new Rust is a small, edge-level integration test with explicit constants for its fixture input and suite contract (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:34-45), then a single test function that follows the clear pipeline compile_to_dag → run_suite → assert published outcomes (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:47-96). The use of include_str! is appropriate here because the fixture source is the interface under test, and compile failures are surfaced directly rather than silently defaulted (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:49-62).

1. TESTING.md.

Compliant — this is intentionally an integration test because the subject is the .dag TestClaim fixture lowering plus runner dispatch, not a unit-level lens behavior. The test names its behavioral claim clearly (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:47-48), asserts fixture compilation diagnostics are empty (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:51-55), asserts the six-claim suite order (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:65-70), and pins the exact regression it exists to prevent: missing PB census dispatch returning NotYetImplemented (src/v3/compiler/tests/integration/r1c_d_pb_census_gates_test.rs:72-83).

1. LOCKED DESIGN DECISIONS.

Compliant — the diff references the locked/roadmap direction rather than changing it: the fixture frames itself as the .dag release-gate layer required by “Tests are structural data” (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:4-6) and explicitly records that zero-bound census gates remain RED until the Pure Bootstrap to Zero cascade retires the residual lists (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:17-21). No divergence from those decisions is introduced in this diff.

1. TRACKED vs UNTRACKED DEBT.

Compliant — the new hand-Rust shim is tracked, bounded, and has a dissolution trigger. The SG-0 census update documents the scope as the R1C-D runner receipt for the six PB census gates (src/v3/compiler/tests/integration/sg0_census_test.rs:281-285), bounds it to the single new path (src/v3/compiler/tests/integration/sg0_census_test.rs:289), and names the dissolution trigger as R1 close / cascade-promotion zero-floor work (src/v3/compiler/tests/integration/sg0_census_test.rs:286-288). The fixture also names the current RED state and the owning Pure Bootstrap to Zero pacing rather than presenting the red gates as completed (src/v3/compiler/tests/fixtures/r1_pb_census_gates.dag:17-28).

3. Verdict

APPROVE

The PR is a narrow, well-documented test/fixture receipt: it adds the .dag PB census gate layer without moving the SG-0 census authority, and it ratchets runner dispatch against NotYetImplemented instead of pretending today’s RED zero-floor gates are green. I did not find a diff-local invariant or testing violation that warrants a finding.
