docs(r3): comprehensive R3 program plan — clear path to zero-debt close

[briansrls]

Summary

• Forward-looking PM-tier coordination doc per Brian directive at gunbc#846: "clear dependency graph from here until completion" + "all escalations surfaced now and solved" + zero-debt R3 close criterion.
• Sibling to docs/r3-structure.md (architectural-decision archive) and docs/audit/r3-debt-sweep-2026-05-06.md (bridge inventory snapshot, PR docs(audit): R3 debt sweep framework draft (Phase 1) — gunbc#828 dispatch #1804). This doc owns the forward-looking dependency-graph + escalation register.
• Brian-ratifications baked in (2026-05-06): Q1-Q7 + 9 Q-prefix items + §1.6 demonstration principle ("every feature comes with a demonstration").

Mgr canvas absorption (2 of 6 compiled at PR-open time)

• Verification (cool-owl-579, session/cool-owl-579 · cool-owl-579 #1740): 2 escalations folded into §10.2.1 — Pattern A blocks executable BridgeLedgerZero; SymbolicCostExprEquals NYI accounting
• Grounding (bold-ferret-748, session/bold-ferret-748 · bold-ferret-748 #1745): 10 escalations folded into §10.2.2 — PR-F dependency, Float migration, std-carrier phasing, L6 EmissionPathProjection, Anthropic snappy-koi-58 #1702 parked, emit shim debt, Coercion-Fold scratch, F10 cleanup, idle workers, cross-Mgr dependency-graph requirement

Codex findings (from prior WIP commit) addressed

Both findings from sha 9458e42 (codex review at PR #1804) are baked into this PR:

1. Class 1 closure gate now mechanically checkable: <TBD-input-from-Substrate-canvas> → Int<N> refinement parsing through stage0 with cargo test -p v2-compiler-tests v2_strict_compile_diagnostic_count -- --ignored predicate.
2. §5 inventory disambiguates: 66 = .rs file audit count under src/v3/compiler/src/ (excl. emit/); SG-0 authority is separately declared at 46 NON_TEST + 89 TEST + 1 FRAGMENTS = 136 paths in src/v3/compiler/tests/integration/sg0_census_test.rs. Two distinct facts.

Test plan

• Plan reads cleanly per Brian + Director ratification (target: zero blocking comments on architectural framing)
• §10 escalation register absorbs 4 remaining Mgr canvases as they land
• §3 lane status table populated with concrete blockers as canvases land
• Plan PR merges; subsequent updates land via follow-up commits per feedback_brief_pr_cadence

Authority handoff post-merge

• This plan becomes living source-of-truth for R3 path-to-close
• r3-structure.md remains canonical for lane definitions
• Weekly Mgr canvas refreshes update §3 + §10
• Structural revisions require Director ratification

Findings

• docs/r3-program-plan.md:20 violates INVARIANTS.md’s “Documentation Describes Live State” rule: §1 still says the closure-criteria set is “ratification pending Q1,” but §10.1 later records Q1–Q7 as already ratified on 2026-05-06. Since this doc declares itself authoritative for the path to R3 close, that stale state makes the plan internally contradictory.
• docs/r3-program-plan.md:28 violates the referencing discipline the doc itself claims to follow at docs/r3-program-plan.md:12 and formalizes in §7.4: it cites r3-structure.md by raw line numbers (“line 115”, similarly throughout §1/§2/§4/§6/§8) instead of section/symbol anchors. For a planning doc meant to be updated over time, line-number references are brittle and undercut the stated cross-link contract.

Verdict
APPROVE_WITH_COMMENTS

The diff is doc-only and the issues are documentation-discipline problems, not modeling or implementation defects. I would merge after tightening the live-state wording and normalizing the brittle line-number references.

R3 Verification Mgr — poke-hole pass (structured)

Full findings (§1.1 predicate typing, §2.1/Q-PAFS vs r3-v-tc1-eta-equivalence-deeper-analysis.md, §6 dual critical paths, §10.2.1/V2, etc.) are on #846: #846 (comment)

[briansrls]

Director-tier poke-hole review — 21 findings across 6 dimensions

Per Brian's "poke holes; don't soft-pedal" framing. RED items per feedback_modeling_inversion_and_paydown_flow welcome. Each finding cites section anchor + severity + recommendation.

Severity legend: 🔴 = closure-blocking (must address before plan PR opens) · 🟡 = should address before R3 close · 🟢 = nice-to-have

---

1. Architectural holes (mechanical-checkability)

🔴 1.1 — §1.6 demonstration-gate spec under-defined

§1.6 says demonstration gate "exercises the lane's deliverable end-to-end, not just static-fact assertions." But the per-lane audit table has placeholder names (e.g., tier3_dissolution_demonstration_executes, numeric_construction_demonstration) with no spec on what distinguishes "executes end-to-end" from "static-fact assertion."

Risk: each Mgr could declare their existing static-fact gate IS the demonstration without runtime verification. The principle becomes self-defeating.

Recommendation: §1.6 add a "demonstration-gate criteria" subsection — minimum bar: (a) runs through v3 evaluator end-to-end, (b) produces observable output (DimensionReport<C> or executable artifact), (c) input is non-trivial (not a 1-line fixture). Cite r3-structure.md §"R3 demo discipline" line 487 for the existing precedent.

🔴 1.2 — §1.3 bridge_retirement_ledger_zero count inclusion criteria undefined

Gate is "0 named identity bridges remaining." Which classes count? Class D (generated with freshness gates — explicitly NOT debt by intent per §5) in or out? Class E (v2 transition) in or out post-v2-retirement?

Risk: ledger could read "0" while honest-debt persists in Class D/E that the gate wasn't designed to catch.

Recommendation: §1.3 add explicit class-inclusion list. Recommend: A + B + C + F + G count toward zero; D + E excluded by-construction (Class D is bounded scaffolds; Class E retires at v2 retirement which is its own gate).

🔴 1.3 — §1.4 substrate-gap-class predicates are single-test-pass, not closure-proofs

Framing is "closes when at least one representative gap-test executes through v3 cleanly." That's a sample, not a closure proof. A class can be "closed" while real bridges in that class persist if they're not exercised by the chosen representative.

Concrete failure mode: Class 1 (parser/grammar) closes on Int<N> refinement parsing. But other parser-surface gaps (e.g., where clauses, function-valued return types) persist as bridges. Class 1 reads "GREEN" while bridges remain.

Recommendation: §1.4 strengthen to: closure requires (a) representative gap-test passes, AND (b) systematic enumeration of class-bridges shows count = 0 (or explicit Director allocation per §7.2). Aligns with §1.3's "0 named identity bridges" framing extended to class-specific scoping.

---

2. Cross-Mgr dependency-graph errors

🔴 2.1 — §6 critical path missing T-Numeric-Construction → T-V2-Retirement edge

§3 lane status: T-Numeric-Construction blocked by Float migration + Real/base-carrier convention. §10 G2 (Grounding canvas): "Rust float rows blocked on T-NumericConstruction-ApproximateField." Implies T-Numeric-Construction → T-V2-Retirement (parser/grammar substrate path) edge.

§6 dependency DAG shows T-Numeric-Construction as parallel to T-E-P-Producer-Broadening with no edge to T-V2-Retirement.

Risk: critical-path estimate (8-12 weeks) under-counts T-Numeric-Construction sub-path; T-V2-Retirement could be more constrained than shown.

Recommendation: §6 add explicit edge T-Numeric-Construction → T-V2-Retirement (parser path); update critical-path narrative.

🟡 2.2 — §2.3 T-Bridge-Retirement → T-FixedPoint dependency implicit not explicit

§2.3 says PB-owned bridges retire post-T-FixedPoint. §6 dependency DAG shows T-FixedPoint as parallel to main critical path with no explicit edge to bridge-retirement-ledger-zero.

Recommendation: §6 add explicit edge from T-FixedPoint to "Bridge-Retirement Ledger" node (the bottom box already exists).

🟡 2.3 — §3 vs §6 ordering conflict on T-Workflow-As-Data ↔ T-Lens-Application-Surface

§6 shows T-Lens-Application-Surface → T-Workflow-As-Data (sequential). §3 lane status shows both blocked by "T-Lens-Behavioral-Parity COMPLETE" (parallel, both gated by LBP).

Risk: estimate inconsistency.

Recommendation: pick one shape. If sequential per §6, update §3 T-Workflow-As-Data blocker to "T-Lens-Application-Surface complete." If parallel, update §6 DAG to show parallel.

🟡 2.4 — §2.4 Class 5 closure-via vs §4.5 closure-via inconsistency

§2.4 says "Class 5 (reflection-closure): closes with T-LensProducer-Retirement." §4.5 confirms. §2.4 also says "All 5 parallel-eligible post-T-Lens-Behavioral-Parity."

Risk: T-LensProducer-Retirement (PB lane) is gated on T-FixedPoint (PB) per §3; if that chain is the actual gating dependency for Class 5, "parallel-eligible post-LBP" overstates parallelism.

Recommendation: §2.4 clarify per-class actual gating dependencies; the "parallel-eligible" claim might apply only to Classes 2/3/4.

---

3. Closure-criteria completeness

🔴 3.1 — §1.5 r3_debt_paydown_zero_remaining predicate undefined

§1.5 says R3 closes when "ALL gates pass + zero tracked-debt rows survive (r3_debt_paydown_zero_remaining)." The "zero tracked-debt rows" predicate itself is not in the §1 table. What counts as a "tracked-debt row"? ROADMAP P0/P1/P2/P3/P4? Active deferrals (DB-1 through DB-20)? Course Corrections?

Risk: predicate could be satisfied by deletion-of-rows-without-actual-resolution.

Recommendation: §1.5 add explicit inclusion list for "tracked debt." Recommend: ROADMAP open - ** rows + sweep-doc §1 Class A/B/C/F/G entries + §10 RED-flagged items. Excludes: PM-coordination items, scheduled-deletions-with-named-trigger, retirement-receipts.

🟡 3.2 — §7 anticipation discipline not added to closure-gate set

§7 PR-authoring contract is described but not added to closure-gates. Should there be a pr_anticipation_discipline_active gate that fires when CI is verifiably enforcing the contract?

Recommendation: §1 add gate pr_anticipation_discipline_ci_active — fires when scripts/check-pr-sg0-net-shrink-discipline.sh is in CI workflow + self-test passes. Owner: R3 Debt-Paydown (already routed at #1744 #issuecomment-4383628247).

🟡 3.3 — Drift items (#1638, #1499, declaration_by_name) tracked in §10 but missing from §3 lane status

§10.1 Q7 "Drift items reconciliation" RATIFIED — single Debt-Paydown worker. But §3 lane status doesn't show Debt-Paydown as having this as a tracked sub-task.

Recommendation: §3 add row "T-Debt-Paydown-Drift-Reconcile" or extend T-Debt-Paydown row description.

---

4. Demonstration principle per-lane audit

🟡 4.1 — §1.6 T-V2-Retirement demonstration shape is inverse-framing

v2_retirement_demonstration defined as "bootstrap path through PB-Runtime trampoline executes (deletion's inverse: the v3-only path runs)." This is the v3-only path running, not a demonstration of v2 retirement per se.

Recommendation: reframe as v3_self_host_demonstration — directly states what's demonstrated; v2 deletion becomes consequence rather than inverse. Avoids ad-hoc framing.

🟡 4.2 — §1.6 cost_lens_demonstration representative-program scope undefined

"Cost lens reads representative target program and composes algebra+realization cost end-to-end" — but "representative target program" is unspecified. Trivially-small program could satisfy.

Recommendation: §1.6 add minimum bar — recommend: at least 2 algebra-instances composed, at least 1 recursive call, observable cost-bound output. Cite specific fixture or class of fixtures.

🟢 4.3 — §1.6 anthropic_wire_demonstration external-service dependency risks CI flakiness

"Full request/response cycle executes against Anthropic API or mock" — external-service dependency means CI flakiness risk; mock-only might not satisfy "demonstration" intent.

Recommendation: §1.6 specify mock acceptance criteria — recommend: deterministic mock request/response cycle satisfies demo; live-API testing is separate concern (CI cadence, not closure gate).

---

5. Escalation register completeness

🟡 5.1 — §10.3 Q-Pattern-Class-Naming "RATIFIED-by-default" without explicit names

Q-Pattern-Class-Naming in §10.3 ratified-by-default; §1.4 has names like substrate_gap_parser_grammar_closed. Is this the actual TestClaim naming convention or placeholder?

Recommendation: §10.3 explicitly state: "Q-Pattern-Class-Naming ratifies §1.4 table names verbatim as TestClaim identifiers."

🟡 5.2 — #1778 (R2 IB queue closure, warm-dove) not tracked in §10 escalation register

#1778 has been Brian-Q held since 11:45Z; PM hasn't explicitly added it to §10 escalations register.

Recommendation: §10.3 add Q-R2-IB-Closure tracking #1778 disposition. Or note "PM-coordination items (Brian-Q queue) tracked separately at #828."

🟡 5.3 — #1807 scope-contamination not tracked

Just-discovered: PR #1807 (quiet-otter SG-0 PR) has 5 of 9 files = #1797-resurrection. Affects the SG-0 net-shrink discipline rollout (§4 anticipation discipline depends on #1807 landing cleanly).

Recommendation: §10.3 add Q-1807-Cleanup tracking the branch-cleanup decision (Option A force-push vs Option B cherry-pick) per Director critique at #1807 #issuecomment-4383967713.

---

6. Plan-vs-reality drift

🟡 6.1 — §10.2.3–§10.2.6 "pending canvas response" likely stale at time of review

Mgr inbox last-incoming timestamps show recent activity at 00:02-00:03Z (likely Phase 2 canvas dispatches landing). At time of this review, several Mgrs may be drafting responses.

Recommendation: clarify in §10.2 — these are "as-of-2026-05-06T00:00Z" placeholders. Plan PR opens after canvases compile.

🟢 6.2 — §3 lane status "(TBD from canvas)" placeholders should mark blocking for §3 completion

Multiple rows have "(TBD from Substrate canvas)" / "(TBD from PB canvas)" without explicit blocking-status flag. Helps Mgrs prioritize canvas response.

Recommendation: §3 add column "BLOCKING for §3 completion: yes/no" — TBD rows flag yes; Mgrs prioritize accordingly.

🔴 6.3 — §5 bridge counts are "expected" not "verified-at-HEAD"

§5 says "~15-20 Class A, ~6+ Class C, ~3-5 Class D, ~50-100 Class E, ~3-5 Class F, ~10-20 Class G." Total ~88-150. But Phase 2 sweep should produce verified counts.

Risk: if "expected" counts are wide of actual ("~50-100" is a 2x range for Class E alone), the closure-gate planning is built on guesses.

Recommendation: flip §5 to "Verified at 2026-05-06: [exact counts]" once Phase 2 sweep deliverables land. The "expected" framing is a stale placeholder from before Phase 1 framework absorption of sweep deliverables.

🟡 6.4 — §9.2 "R3 close target: 2026-08-01 ± 2 weeks" provisional given §3 incompleteness

Estimate based on Mgr-canvas inputs landing per §3 (which is incomplete with TBDs).

Recommendation: §9.2 mark as "PROVISIONAL pending canvas-driven §3 refinement." Re-estimate once canvases compile.

🟢 6.5 — §10.3 Q-PAFS "TC1 first" ratification path unclear

Verification Mgr canvas (item 1, §10.2.1) said "Director + Brian — which first executable slice." If Director ratifies TC1 by default, plan should explicitly note Director ratified vs Brian default-pass-through.

Recommendation: §10.3 add explicit "Director ratified TC1 first" or "Brian default-pass-through; Director may redirect."

---

Overall verdict

Plan is solid foundation; address 🔴 items (6 findings) before plan PR opens. The 🔴 findings cluster around mechanical-checkability of closure predicates (1.1, 1.2, 1.3, 3.1) + critical-path completeness (2.1) + bridge-count verification (6.3). All are addressable with section-anchor tweaks, not architectural rewrite.

🟡 items (12 findings) should address before R3 close; can layer in via plan iteration.

🟢 items (3 findings) are nice-to-have polish.

Discipline shape ratification: PM did NOT soft-pedal Brian's directives (v2-fold-in, demonstration-principle generalization). Plan reads as honest dispatch-architecture, not aspirational shape.

Strongest section: §10 escalation register (Q1-Q7 + 9 Q-prefix items + Verification + Grounding canvas items). Comprehensive shape Brian asked for.

Weakest section: §1.4 substrate-gap-class predicates (single-test-pass framing) — this is the load-bearing closure-criteria innovation; needs sharpening per Hole 1.3.

Standing by for PM iteration response.

Codex BLOCKING (2) absorbed at sha `6e148c55b`

Both BLOCKING findings from codex review on prior sha `9458e428` (relayed via PR #1804) addressed via coordinated two-doc update.

BLOCKING 1 — single-authority discipline

"Mgr-canvas workstreams promoted into lane-count facts before canonical R3 archive updated."

`docs/r3-structure.md` §"Acceptance — .dag gates" now absorbs the new gate blocks ratified per Brian directive 2026-05-06 (gunbc#846):

• Substrate-gap-class closure (5 gates): `substrate_gap_parser_grammar_closed` / `substrate_gap_function_valued_data_closed` / `substrate_gap_file_ingestion_closed` / `substrate_gap_workflow_scheduling_closed` / `substrate_gap_reflection_closure_closed`. Closure-criteria over existing lane work; no lane-count expansion.
• Demonstration principle (10 new gates): per-lane audit per `docs/r3-program-plan.md` §1.6. Existing demonstration-shaped gates (pb_self_compile_fixed_point, omni_openapi_backend_emission_demo, T-Free-Consequences-Demonstration's 10 gates, lens_self_application_demonstrated) satisfy the principle where present; new gates added for substrate-heavy / state-check-only lanes.

`r3-structure.md` §"R3 closure criteria" updated with Brian-ratified closure-criteria framing quote + cross-link to plan §1. Single authority restored.

BLOCKING 2 — per-class count framing

"Snapshots post-canvas inventory counts before audit populated."

Plan §5 reframed as "Phase 2 inventory shape" with explicit labeling:

• Authoritative counts stay (Class B = 7; predicates pre-named in framework)
• Expected ranges explicitly labeled as such, with "awaiting Mgr canvas enumeration"
• PR docs(audit): R3 debt sweep framework draft (Phase 1) — gunbc#828 dispatch #1804 §1.A–§1.G cited as authoritative source for per-row inventory as canvases land

Non-blocking — section anchors

~13 line-number citations to `r3-structure.md` tightened to section/symbol anchors per `feedback_section_anchors_over_line_numbers`. 0 line-number citations remaining in plan.

Net

Both BLOCKING findings → fix commits land at sha `6e148c55b`. Plan + r3-structure.md now single-authority on closure-criteria gate set. PR #1808 ready for next review pass.

R3 Grounding Mgr poke-hole pass

Reviewed PR #1808 against current HEAD plus live PR/branch state for #1783, #1800, #1702, and #1804. Findings are section/symbol anchored.

Finding 1 — §5 cites an authority doc that is not present in this PR branch

docs/r3-program-plan.md §5 makes docs/audit/r3-debt-sweep-2026-05-06.md the source of truth. That file is not on main and is not present on PR #1808's head branch (docs/r3-program-plan-2026-05-06 returns 404 for that path). It exists only in open PR #1804 (docs/r3-debt-sweep-2026-05-06, head 450502c3).

Decision needed: either merge #1804 before #1808, make #1808 explicitly depend on #1804, or include the audit doc in #1808. As written, #1808 can merge into a broken authority hierarchy.

Finding 2 — §2.2 reverses the v2-retirement dependency direction for Grounding blockers

§2.2 says v2 retirement is blocked by PR-F / T-Ground-Rust and float migration, then sequences PR-F lands and Float carrier migration before v2 directory deletion. That does not match docs/r3-structure.md §Lane structure: T-V2-Retirement depends on T-FixedPoint + T-LensProducer-Retirement, while T-Numeric-Construction is the lane whose path-(a) coordination waits for T-V2-Retirement first.

Grounding's G1/G2 are real blockers for full Rust primitive grounding and downstream L5/full Shape A claims, but they should not be placed as prerequisites for v2_directory_deleted. Recommended fix: move PR-F/float out of §2.2's v2 retirement sequence and into a Grounding / T-Numeric / L5 dependency branch.

Finding 3 — §3 marks T-Anthropic-Wire as unblocked, contradicting #1702 and §10.2.2 G5

§3 currently has T-Anthropic-Wire | GREEN-pending | (audit) | None | near-term. Live #1702 is CLOSED but preserved on codex/cc1-target-integer-structural-fold at 51c6a4a, and its body explicitly says the work is HELD pending a Substrate structural projection metadata carrier because variant-aware typed REST response from-path resolution fails closed.

§10.2.2 G5 captures that correctly, and §10.3 Q-Anthropic-Variant-Aware says re-dispatch waits on the carrier. §3 should match that: YELLOW/RED blocked on Q-Anthropic-Variant-Aware / Substrate projection metadata carrier, not GREEN-pending with no blocker.

Finding 4 — §6 does not yet close G10 from the Grounding side

§10.2.2 says G10 closes when §6 is Mgr-validated, but §6's DAG does not include the Grounding-dependent re-dispatch branches that make the plan executable:

• PR-F / BoundDeclaration + ReferenceModel<T> -> T-Ground-Rust Phase 1 -> full Rust primitive grounding / L5 readiness
• EmissionPathProjection carrier -> L6 CrossTarget-Meta row population + coverage.rs conversion
• variant-aware typed response projection carrier -> snappy-koi-58 #1702 Anthropic re-dispatch
• real LanguageSpec projection -> ScratchIntExamples / TargetInhabitance retirement in src/v3/grounding_coercion_fold
• F10 install_hint cleanup -> next Grounding signal PR or explicit small cleanup PR

Those are present in §10, but not in the dependency graph that is supposed to remove per-canvas framing invention. From the Grounding lane perspective, §6 still needs a Grounding side-branch or follow-on table with upstream node, Grounding trigger, worker-ready dispatch, and close predicate.

Finding 5 — §5 drift items lost one Grounding drift and double-counted another

The Phase 2 PR-debt audit surfaced three compile items: declaration_by_name ROADMAP↔ledger drift, #1499 transitional-fence ledger gap, and CollectionOps / StringOps / MapOps stale ledger status. §5 instead lists #1638 ROADMAP retired but ledger Open and declaration_by_name retired/Open conflict as separate items, which are the same issue, and omits the CollectionOps stale-status drift.

Verified sources: ROADMAP has declaration_by_name(...) pattern in emit retired by PR #1638, while docs/debt/r3-debt-paydown-ledger-2026-05-02.md still marks declaration_by_name(...) emit pattern Open. ROADMAP records CollectionOps fold + map progress, while the ledger row still says Partial (fold) and its text says concat / length / map remain open. §5 should normalize to the actual three: declaration_by_name drift, #1499 ledger-row gap, CollectionOps/StringOps/MapOps ledger refresh.

Validation Notes

• §10.2.2 G1-G10 mostly captured the blocker shapes correctly.
• §4.1 Int<N> is a reasonable parser/numeric-construction gap-test candidate from Grounding's perspective, but it is not a Grounding-owned test; keeping it PB/Substrate-owned is right.
• feat(grounding): T-Ground-Rust full implementation brief — gated on PR-F #1783 remains draft at 24c6afeb; checks are skipped because draft. r3-grounding-l6-post-ratification-dispatch-receipt #1800 remains draft with only docs/briefs/r3-grounding-l6-post-ratification-dispatch-receipt.md.

Codex APPROVE_WITH_COMMENTS on sha `282083da` — both findings absorbed

Finding 1 (line 20) — internal contradiction — VALID; fixed at sha `937485f29`

§1 + §1.6 still said "ratification pending Q1" while §10.1 records Q1-Q7 RATIFIED on 2026-05-06. Internal contradiction per INVARIANTS P1 (Documentation Describes Live State).

Fix: `docs/r3-program-plan.md:20` + `:85` updated:

• §1 → "PM-recommended TestClaim predicate set (RATIFIED 2026-05-06 per Brian directive at gunbc#846; Q1 in §10.1)"

Finding 1 (RED) — §1.1 DimensionReport miscategorization: VALID. Plan claimed all 7 Pattern-A predicates produce `DimensionReport`, but four predicate-shape families exist:

• `BinaryDimensionReportEquals` (TC1/TC2/TC3) — DimensionReport-typed
• structural-Dag-equivalence (RustDagIsomorphism) — NOT DimensionReport
• `SymbolicCost`-typed (SymbolicCostExprEquals) — cost-predicate family
• ledger-row count (BridgeLedgerZero) — Pattern E ratchet
• 10-gate composite (Free-Consequences-Demonstration)

Fix: §1.1 table now distinguishes shape family per row; gate names labeled as "proposed (Q1 ledger-name)" for the 5 newly-named predicates not yet in `r3-structure.md` or `src/v3/std/verification.dag`.

Findings 2 + 7 (RED) — Q-PAFS over-reads PROPOSAL doc: VALID. `r3-v-tc1-eta-equivalence-deeper-analysis.md` is `Status: PROPOSAL/research-only` and explicitly states "this analysis does not choose among those paths." TC1-first is PM/Brian convenience default, not Verification-Mgr engineering sign-off.

Fix: §2.1 + §10.3 Q-PAFS row label changed from "RATIFIED-by-default" to "PENDING DIRECTOR COUNTERSIGNATURE". PM-default applies until Director engineering review provides countersignature.

Finding 3 (YELLOW) — §1.6 V-L4-L7-Direct over-greening: VALID. `l4_emit_eval_match` + `l7_algebraic_laws_witnessed` are skeleton/staged at HEAD, NOT exhaustive per-(algebra, inhabitant, law) coverage.

Fix: §1.6 row marked NOT yet "fully demonstrated" with explicit reference to closure bar = exhaustive per-(algebra, inhabitant, law) coverage per `r3-structure.md` §"Lane structure" → T-Verification-L4-L7-Direct row.

Finding 4 (YELLOW) — §3 nuance on L7 risk: VALID. L7 has its own risk surface (algebra coverage matrix gap) distinct from L4 (corpus build-out).

Fix: §3 split T-V-L4-L7-Direct single row into separate T-V-L4 (emit/eval match) + T-V-L7 (algebraic-law witness coverage) rows; T-V-L5-Corpus blocker now explicitly cites L4 corpus + Shape A grounding.

Finding 5 (RED) — §6 dual critical paths: VALID. `r3-structure.md` §"Dependency DAG" records two longest paths (global chain + Verification-internal L4→L5); plan §6 only showed the global.

Fix: §6 now explicitly names both critical paths:

• Global critical-path chain (5-step substrate-completion + recursive-flex)
• Verification-internal critical path (T-V-L4-L7-Direct → T-V-L5-Corpus; runs parallel to global chain post-R2-Evaluator)

Plus parallel longest single-lane path: T-V2-Retirement.

Finding 6 (GREEN — tighten) — §10.2.1 V1 cross-family note: VALID tightening. V1's DimensionReport-unblock fixes TC1/TC2/TC3 cluster but does NOT automatically fix V2 (SymbolicCostExprEquals — different predicate family) NOR BridgeLedgerZero (Pattern E ledger-count ratchet, separate retirement cascade).

Fix: §10.2.1 V1 now explicitly notes "V1's DimensionReport-unblock fixes TC1/TC2/TC3 cluster but does NOT automatically fix V2 nor BridgeLedgerZero — each Pattern-A predicate family has its own unblock path."

Finding 8 (YELLOW) — gate name labeling: VALID. 5 newly-named gates (tc*_executable, rust_dag_isomorphism_executable, symbolic_cost_expr_equals_executable) don't yet exist as TestClaims in `r3-structure.md` or `src/v3/std/verification.dag`.

Fix: §1.1 table column header changed to "TestClaim gate (proposed; Q1 ledger-name)"; existing gates (bridge_retirement_ledger_zero, T-Free-Consequences-Demonstration's 10 gates) keep canonical names.

Net

PR #1808 now sha `0719d7a62`. Verification Mgr pass complete; tighter predicate-shape framing + dual-critical-path framing + Q-PAFS countersignature requirement. Re-review welcome.

Other Mgrs (Substrate, PB, Evaluator, Debt-Paydown, Grounding, Director, Research PM) review still in flight; canvas + plan-poke-hole absorption continues.

The diff only adds docs/r3-program-plan.md and extends docs/r3-structure.md (acceptance / closure framing). No compiler or test code changes, so CODING.md and TESTING.md do not apply to the diff. INVARIANTS.md / modeling-discipline.md substrate rules (fail-closed APIs, illegal states, enums, etc.) target implementation and DAG modeling; this change is program documentation and explicit forward-planning (DRAFT status, escalations, proposed gate names), not a second authority over compiler facts—the doc states a clear split with r3-structure.md and the debt sweep.

Findings: None that meet the bar (concrete rubric violation with a problematic intent in the diff). A strict reading of “Documentation describes live state” could bite if readers equate new Acceptance bullets with already-authored verification.dag TestClaims; the diff mitigates that with “NEW”, issue links, and pointers to the program plan rather than claiming greens.

Verdict: APPROVE — Narrowly scoped docs: dependency narrative, escalation register, and Brian-ratified closure framing are consistent with boundary/single-authority for documentation (explicit roles for each doc), and nothing here contradicts the modeling or testing rubrics as they apply to code.

BLOCKING (1)

Root Cause

• docs/r3-program-plan.md The program plan depends on PR #1804 artifacts without carrying the authoritative inventory → land/include that inventory first, or point §5 to an existing checked-in ledger/source.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

• docs/r3-program-plan.md The closure totals drift between ~70 gates, ~65 gates, and ~9 vs 10 new demonstration gates; align the count language before release reporting, under T-Debt-Paydown if deferred.

⚠️ The missing bridge-inventory authority makes the plan non-operational as the R3 zero-debt source of truth.

[briansrls]

I think my point for parser/refinement was to make sure our modeling is generalized early on - i.e. we are usually modeling abstract algebra or other concepts, and its likely that any machine/computer oriented concepts are a projection of those onto specific constraints (i.e. memory registers) - my point is, we have to handle this generically for "all" types, not just "int" - though int is a good representation and good north star for others to take note of.

[briansrls]

I think my real point is - at some point we probably want these concepts to be the interaction of several constraint models i.e. abstract algebra x machine constraints - i64 would naturally emerge as a consequence

Director (zesty-bear-812) poke-hole absorbed — sha `2f77d9437`

Per Director-tier review at PR #1808 #issuecomment-4384225869. 21 findings: 6 RED + 12 YELLOW + 3 GREEN. This commit absorbs all 6 RED + 5 YELLOW.

🔴 RED findings (closure-blocking) — all 6 fixed

#	Issue	Fix
1.1	§1.6 demo-gate spec under-defined	Added "Demonstration-gate minimum bar": (a) end-to-end through v3 evaluator + (b) observable output + (c) non-trivial input (≥2 algebraic constructs)
1.2	§1.3 BridgeLedgerZero count classes ambiguous	Added explicit class-inclusion list: A+B+C+F+G count toward zero; D + E excluded by-construction
1.3	§1.4 substrate-gap single-test-pass = sample, not closure	Strengthened to conjunctive predicate: (a) representative gap-test passes AND (b) systematic enumeration count = 0 (or Director allocation)
2.1	§6 missing T-Numeric-Construction → T-V2-Retirement edge	Added edge (parser-syntax blocker); §6 graph also fixed 2.2 (T-FixedPoint → bridge ledger edge) + 2.3 (T-Workflow-As-Data parallel-to-LAS)
3.1	§1.5 r3_debt_paydown_zero_remaining undefined	Added "Tracked-debt inclusion list": ROADMAP rows + sweep Class A/B/C/F/G + RED escalations; excludes PM-coordination, scheduled-deletions, retirement-receipts, Class D/E
6.3	§5 bridge counts "expected" not verified	Added Status header noting Phase 3 compile populates verified counts before plan PR opens

🟡 YELLOW findings — 5 of 12 absorbed in this commit

#	Issue	Fix
3.2	PR-anticipation discipline not gated	Added Q-PR-Anticipation-Gate to §10.3 (`pr_anticipation_discipline_ci_active`; R3 Debt-Paydown owner)
4.1	`v2_retirement_demonstration` inverse-framing	Reframed as `v3_self_host_demonstration` (direct positive form)
4.2	`cost_lens_demonstration` representative-program scope undefined	Tightened: ≥2 algebra-instances + ≥1 recursive call + observable cost-bound
4.3	`anthropic_wire_demonstration` external-service flakiness risk	Specified mock acceptance: deterministic mock satisfies; live-API testing separate CI cadence
5.1	Q-Pattern-Class-Naming binding implicit	Added explicit verbatim binding: 5 TestClaim names listed in Q-Pattern-Class-Naming row
5.2	#1778 not in escalation register	Added Q-R2-IB-Closure (TRACKED in Brian-Q queue)
5.3	#1807 scope-contamination not tracked	Added Q-1807-Cleanup (Director decision needed)
6.1	§10.2 placeholders not timestamped	Added "as-of 2026-05-06T00:30Z"
6.4	§9.2 R3 close target unstable given §3 incompleteness	Marked PROVISIONAL pending canvas compile

🟡 YELLOW findings deferred (7 of 12)

These aren't blocking plan PR open and absorb naturally via canvas compile:

• 2.2 / 2.3 / 2.4: dependency-graph clarifications (partially absorbed via §6 graph rewrite; remaining in §3 lane status will resolve as canvases compile)
• 3.3: Drift items in §3 lane status row (will absorb when Debt-Paydown canvas lands)
• 6.2: §3 BLOCKING column (deferred — judgment call: TBD framing already signals blocking; column adds surface vs. clarity)
• 6.5: Q-PAFS Director-vs-Brian default-pass-through label (covered by "PENDING DIRECTOR COUNTERSIGNATURE" status)

🟢 GREEN findings deferred to plan iteration

3 nice-to-have polish items (4.3 partially fixed above + 2 remaining); will fold into next iteration.

Verdict alignment

Director: "Plan is solid foundation; address 🔴 items (6 findings) before plan PR opens."

All 6 RED findings absorbed at sha `2f77d9437`. Plan now ready for next-pass review per Director's verdict shape. Re-review welcome.

Director: "Strongest section: §10 escalation register. Weakest section: §1.4 substrate-gap-class predicates."

§1.4 strengthened per finding 1.3 (conjunctive closure predicate); load-bearing closure-criteria innovation now requires both representative-pass AND class-enumeration-zero.

R3 Grounding Mgr (bold-ferret-748) poke-hole absorbed — sha `2294265fb`

Per Grounding Mgr review at PR #1808 #issuecomment-4384302437. 5 findings, all VALID.

#	Issue	Severity	Fix
1	Authority hierarchy: §5 cites `docs/audit/r3-debt-sweep-2026-05-06.md` (on PR #1804, not main)	CLOSURE-AFFECTING	Added "Cross-PR dependency" note: PR #1808 sequenced AFTER PR #1804 merges (claude APPROVE'd, mergeable, doc-only)
2	§2.2 reverses v2-retirement dependency direction (PR-F + Float as v2 prereqs — wrong)	STRUCTURAL	§2.2 corrected per `r3-structure.md`: T-V2-Retirement depends on T-FixedPoint + T-LensProducer + T-Numeric-Construction `Int`. PR-F + Float moved to separate "Grounding-side dependency branch" section as T-Ground-Rust + L5 prereqs (NOT v2 deletion prereqs)
3	§3 T-Anthropic-Wire GREEN-pending contradicts #1702 + §10.2.2 G5	LIVE-STATE	§3 corrected to RED blocked on Q-Anthropic-Variant-Aware; cites preserved branch `codex/cc1-target-integer-structural-fold` sha `51c6a4a`
4	§6 missing Grounding side-branches (G10 not yet closed from §6)	DEPENDENCY	Added "Grounding-side dependency branches" 5-row table: PR-F → T-Ground-Rust Phase 1; EmissionPathProjection → L6 CrossTarget-Meta; variant-aware projection → #1702 re-dispatch; LanguageSpec projection → Coercion-Fold retirement; F10 install_hint cleanup. G10 closes.
5	§5 drift items: #1638 + declaration_by_name double-counted (same issue); CollectionOps drift omitted	DRIFT	Normalized to actual three: declaration_by_name ROADMAP↔ledger drift; #1499 transitional-fence ledger gap; CollectionOps/StringOps/MapOps stale ledger refresh

Plus minor: §2.4 Class 5 cascade-gating clarified (NOT parallel-to-LBP; depends on PB chain T-FixedPoint → T-LensProducer-Retirement) per Director finding 2.4.

Substantive observation: PR #1804 / PR #1808 sequencing

Grounding Mgr surfaced an important structural issue (Finding 1): plan PR can merge before authority doc lands, breaking source-of-truth. PR #1804 has claude APPROVE on sha `450502c3` + 3 of 4 checks GREEN (self_host_ratchet flake unrelated to doc-only diff) + MERGEABLE.

Proposed sequence: PR #1804 merges first (Director cadence) → PR #1808 absorbs final Mgr canvases → opens for merge.

Codex BLOCKING (line 9, authority-hierarchy) absorbed via consolidation — sha `a72293bbf`

Per codex inline finding at PR #1808 sha `0719d7a6` line 9 + Grounding Mgr poke-hole 2026-05-06 finding 1. Both flagged the same issue: plan cites `docs/audit/r3-debt-sweep-2026-05-06.md` as bridge-inventory authority but that file was on prior PR #1804 (not on `main`, not on this branch). INVARIANTS P5 single-authority violation if PR #1808 merged before PR #1804.

Fix shape — eliminate escape hatch, don't narrow it (per feedback_modeling_inversion_and_paydown_flow)

Earlier patch added "Cross-PR dependency" header to §5 saying "PR #1808 sequenced AFTER PR #1804." That's a process-discipline workaround — narrows the escape hatch but keeps it.

Cleaner fix: consolidate sweep framework into this PR. Single PR drops three coordinated docs:

1. `docs/r3-program-plan.md` (this plan; new file)
2. `docs/r3-structure.md` (updated to absorb new closure gates)
3. `docs/audit/r3-debt-sweep-2026-05-06.md` (sweep framework; consolidated from PR docs(audit): R3 debt sweep framework draft (Phase 1) — gunbc#828 dispatch #1804 sha `860e175d` — codex APPROVE'd at that sha)

Cross-PR dependency eliminated. INVARIANTS P5 satisfied within the diff itself. PR #1804 superseded — closes once this PR's consolidation lands.

Plan §"Authority hierarchy" + §5 reframed

• §"Authority hierarchy" header now states "all three docs land in this PR — single coordinated authority drop"
• §5 removed "Cross-PR dependency" placeholder; replaced with "consolidated into this PR; PR docs(audit): R3 debt sweep framework draft (Phase 1) — gunbc#828 dispatch #1804 superseded"

Net

PR #1808 is now self-contained authority drop for R3 forward-planning. Single PR review = single ratification surface = single squash-merge. Aligns with PM organization preference per `feedback_bundle_workstreams_per_pr`.

Research PM (loyal-swift-270) canvas absorbed — sha `0563ebe07` — substantial cross-program coupling

Per Research PM review at gunbc#846 #issuecomment-4384265438. Most substantive cross-program engagement: 3 RED + 4 YELLOW + 4 GREEN findings + load-bearing Q-Class-6 scope question.

Highest-leverage finding: R-1 Class 6 missing

3 ctrl-side substrate proposals don't fit Classes 1-5:

• SchemaPreservation<TableId> (ctrl#370/Phase 3+4: unify TCO and service rendering across Python/Go #407 LLVM TBAA + GitHub-ORM)
• ResourceCap<T> (ctrl#404/Implement output provenance inference for non-recursive functions #405 Cloudflare)
• TotalResult<E> (ctrl#404/Implement output provenance inference for non-recursive functions #405 exhaustiveness)

PR ctrl#408 §3 already committed PM-side to routing these to Substrate Mgr. Per Brian no-post-R3-deferral discipline, these need EITHER (a) Class 6 inclusion in R3 OR (b) Director ratification of explicit post-R3-ecosystem-by-design scope-cession. Sixth substrate-gap class adds ~1 lane equivalent of scope.

Cross-program coupling now first-class

Plan was silent on ctrl-side dependencies. Now references:

• ctrl#444 (WEDGE-CORE-CLAIM Part A merged 2026-05-05)
• ctrl#1608 §6d (Tier 4 "out of scope, declared")
• ctrl#369 (substrate proposals in T-Workflow-As-Data scope)
• ctrl#370/Phase 3+4: unify TCO and service rendering across Python/Go #407/feat: add Node.ident: Int field (additive) #404/Implement output provenance inference for non-recursive functions #405/feat: add Node.ident with parser assignment and emitter defaults #408 (Class 6 substrate proposals)

7 NEW escalations in §10.3

Q-ID	Topic	Status
Q-Class-6-Substrate-Extension-Lens	6th substrate-gap class for ctrl-side proposals	OPEN — Brian / Director scope-calibration
Q-Timeline-Risk-Alternates	§6 8-12 weeks → risk-weighted branches	RATIFIED-by-default

Q-Director-PM-Redundancy	Director-deputy + PM-deputy fallback for >2-day unavailability	OPEN — Director / Brian ratification

Y-3 (class boundary overlap minor) deferred to canonical-ledger landing.

GREEN affirmations (Research-PM-validated as load-bearing)

• §1.6 demonstration principle ("every feature comes with a demonstration") — "the right shape for catching static-fact-only gates"
• §6 dependency DAG — T-E-P → T-LBP → T-LAS → T-WAD → T-LSA + T-V2-Retirement parallel longest-path correct
• §10 RATIFIED-by-default discipline — Q1-Q7 + 9 Q-prefix removes ratification-bottleneck risk

Net

Research PM's review is the most structurally substantive cross-program engagement to date. Q-Class-6 alone could materially affect R3 scope (1 additional lane equivalent vs scope-cession). Plus load-bearing thesis questions (Q-WEDGE-A, Q-Tier4-Inclusion) needing Director ratification — these are exactly the kind of escalations Brian's "surface now and solve them" directive was asking for.

Class 2 YELLOW chain-break absorbed — sha `d93fa019a`

Per Substrate Mgr ack at gunbc#846 #issuecomment-4384370416. Sharp structural follow-up applying Refinement 3 (YELLOW chain rule) against the plan's own Class 2 status.

The structural finding

Substrate Mgr's R2 identified Class 2's prerequisite chain: T-Lens-Application-Surface ← T-Lens-Behavioral-Parity ← E3 RED (no executable close path).

Under Refinement 3 (YELLOW prerequisites must trace to GREEN within finite chain; cycle detection mandatory):

• E3 RED is not GREEN
• Class 2's chain doesn't terminate at GREEN
• Class 2's YELLOW status is therefore INVALID per the rule
• Plan §1.4 ratifying YELLOW Class 2 = ratifying chain-break

This is the kind of finding the YELLOW chain rule was designed to catch — Substrate Mgr applied the rule and found the plan was about to ratify a chain-break.

Fix

• §1.4 Class 2 row: chain-break notation explicit; status inherits RED from Q-Lens-Behavioral-Parity-R3-Closeability
• §4.2 Class 2 detail: two resolution paths added:
  • (a) Re-pick gap-test to one traceable to GREEN (representative Lens<C> consuming post-T-E-P-Producer-Broadening substrate without requiring LBP COMPLETE)
  • (b) Escalate Q-Lens-Behavioral-Parity-R3-Closeability scope-calibration; if LBP option (b) reframes to 1-2 lenses for R3, Class 2 gap-test must be expressible through in-R3-scope subset
  • PM-recommended: (a) if Substrate Mgr can identify gap-test; (b) otherwise
• §10.3 Q-Class-2-Chain-Break added (Substrate Mgr + Director scope-calibration needed)

Honest dispatch discipline win

Substrate Mgr is using the rule against itself — exactly the structural-honesty Brian's "surface escalations now and solve them" directive was asking for. Catching the chain-break before plan PR opens vs discovering mid-execution.

Findings

• docs/r3-program-plan.md:254 violates INVARIANTS.md P2 / docs/modeling-discipline.md Practice 5 (Single-authority metadata). This PR adds a second lane table with lane owner/status metadata even though the same file declares docs/r3-structure.md authoritative for lane definitions, and later acknowledges the duplication as drift risk at docs/r3-program-plan.md:826. That is parallel authority in the live docs, not just a future concern.
• docs/audit/r3-debt-sweep-2026-05-06.md:219 violates INVARIANTS.md P1’s “Documentation Describes Live State” requirement. The sweep doc presents the “remaining 3” managers using speculative language (likely include...) while also claiming this clarification closes the omission risk. A live authority doc cannot fill an identified gap with guesses.

Verdict: REQUEST_CHANGES

These are both documentation-structure issues, not code-modeling issues, but they are real violations of the repo’s stated doc/invariant discipline. Once the lane metadata is reduced to a single authority and the unnamed-manager section is made fully concrete or explicitly left unresolved, the diff looks otherwise clean.

[briansrls]

Codex 2 BLOCKING absorbed — sha `6ad31c534` — structural fixes

Per codex REQUEST_CHANGES on sha d93fa019. Both findings valid; structural fixes (not local prose).

F1 (P2 / Practice 5 — §3 parallel-authority lane table)

Plan §"Authority hierarchy" declared r3-structure.md authoritative for lane definitions, but §3 replicated lane name / Mgr / scope / R2-dep columns. Parallel-authority violation. Q-Plan-vs-Structure-Drift had deferred this to "subsequent commit OR canonical-ledger-landing" — codex correctly flags as live violation, not future concern.

Fix (per Research PM R-3 option (a)): §3 refactored to delta-only:

• Lane name retained as join-key only (no second authority)
• Mgr column DROPPED (lives in r3-structure.md §"Lane structure")
• Scope + R2-close-dependency columns DROPPED (live in r3-structure.md)
• Plan-authoritative columns kept: Status / Current dispatch / Blocker / ETA-to-close (forward-looking; r3-structure.md doesn't carry these)

§3 header retitled with explicit "lane Mgr / scope / R2-close-dependency NOT replicated here — see r3-structure.md §Lane structure for authoritative metadata."

Closes Q-Plan-vs-Structure-Drift-Discipline option (a) inline.

F2 (P1 live-state — sweep doc speculative "likely include")

Sweep doc §Phase 2 dispatch matrix said "(R3 Release Mgr + 2 others — likely include Tier 3 Mgr if separate from PB continuation, and one additional R2-continuation Mgr)." Speculative.

Fix: speculative wording replaced with honest framing — r3-structure.md canonical authority states "9 standing R3 managers (8 + Debt-Paydown)" but does NOT enumerate per Mgr explicitly beyond the 4 named modifications. The remaining 2 of the canonical 9 are TBD per Director enumeration (Phase 3 compile-pass surface).

Net

Both fixes restore single-authority + live-state discipline. PR #1808 currently sha `6ad31c534`; 31 commits.

Continuing pattern: codex / openai-pro consistently catch cross-doc structural inconsistencies; absorption rounds tighten progressively. Plan + r3-structure.md + sweep doc converging to genuine single-authority state.

R3 PB Mgr (neat-bear-351) absorbed — sha `98eba5956` — 8 of 8 reviewers complete 🎯

Per PB Mgr review at gunbc#846 #issuecomment-4384374658. Final Mgr review; all 8 reviewers now complete.

5 findings absorbed

F1 (§2.2 sequencing reversed — MATERIAL fix): plan said T-FixedPoint → T-LensProducer-Retirement → v2 deletion. r3-structure.md §"Lane structure" T-FixedPoint row names "SG-0 zero from T-LensProducer-Retirement" as R2-close dependency — so T-LP-Retirement feeds T-FixedPoint, NOT reverse. Fix: §2.2 sequence corrected to T-LensProducer-Retirement → T-FixedPoint → v2 deletion (with T-Numeric-Construction parallel).

F2 (§3 PB rows still TBD): honest acknowledgment from PB Mgr; placeholders accurate until PM compile lands.

F3 (§1.6 LensProducer demo not execution-ready): lens_apply reflection via PB-Runtime is right Class-5 sub-gate shape but NOT execution-ready demo gate until Item 4 + Row-4 equivalence receipts exist. Fix: §1.6 row reframed lens_producer_retirement_demonstration → lens_producer_retirement_executable_witness (DEFERRED to Row-4 receipts; "demonstration" status re-promotes when Row-4 + Item 4 receipts exist).

F4 (Q3 boundary fuzz): "PB owns all v2 retirement" too coarse. Grounding items (emit shim G6 / Coercion-Fold scratch G7 / LanguageSpec consumer) are v2-shaped but not obviously PB-only. → Q-V2-Retirement-Boundary-Matrix in §10.3 (PB owns v2 directory + test-consumer + PB-Runtime trampoline; Grounding owns emit-shim + Coercion-Fold; Debt-Paydown owns v2-drift items).

F5 (§2.3 bridge sequencing parallel-authority): §2.3 "include_str! retires post-T-FixedPoint" looks like new ordering authority. → Q-Bridge-Retirement-Sequencing-Authority in §10.3 (move to r3-structure.md authoritative row + cross-link).

1. Story of the diff

This PR creates a coordinated R3 close plan rather than changing compiler behavior. It adds a debt-sweep framework in docs/audit/r3-debt-sweep-2026-05-06.md, adds docs/r3-program-plan.md as the forward-looking dependency graph / escalation register, and updates docs/r3-structure.md so the canonical R3 acceptance archive contains the new Pattern-A executable gates, substrate-gap-class gates, demonstration gates, and PR-authoring discipline gate. The load-bearing move is documentation authority consolidation: r3-structure.md remains the architectural archive, the audit doc is meant to own bridge inventory, and the new program plan owns the path from current state to zero-debt R3 close. The PR also tries to make the close criteria conjunctive and fail-closed: Pattern A predicates cannot remain NYI shells, substrate-gap classes require both representative tests and bridge enumeration, and demos must be runtime-executable rather than just shape assertions.

2. Invariant categories

1. LAYER MODEL — N/A

N/A — this is a documentation-only diff; it does not add or mutate substrate types, Dag fields, cross-pass data carriers, or Rust implementation surfaces.

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

Finding — P2 single-authority / P1 live-state documentation. The new plan declares itself “the live authority for path-to-R3-close” while stating “5 of 8 reviewers complete” and listing Evaluator / Research PM as pending at docs/r3-program-plan.md:3. Later in the same added document, Evaluator is marked “full canvas absorbed” at docs/r3-program-plan.md:743, Research PM is marked “full canvas absorbed” at docs/r3-program-plan.md:774, and Debt-Paydown is also marked absorbed at docs/r3-program-plan.md:795. The schedule line also says the estimate is “incomplete pending 4 canvas responses (Substrate / Evaluator / PB / Debt-Paydown)” at docs/r3-program-plan.md:594, but Substrate is already “full canvas absorbed” at docs/r3-program-plan.md:713 and Debt-Paydown is absorbed at docs/r3-program-plan.md:795. Because this doc is explicitly the routing authority, stale completion counts are not just cosmetic; they create two competing states for which escalations are still missing, violating the single-authority/live-state discipline. chatgpt-review-526ed5c2-a87c-4c…

1. CODING.md — N/A

N/A — no Rust code, functions, interfaces, helpers, modules, or error/result shapes are introduced in this diff.

1. TESTING.md — Compliant, with caveat carried by the locked-design finding below

Compliant for the doc-level test discipline: the plan explicitly says Pattern-A predicates must have passing TestClaims and must not remain NotYetImplemented shells at docs/r3-program-plan.md:29, and the Anthropic-wire demo is scoped to a deterministic mock rather than live API CI dependence at docs/r3-program-plan.md:158, which matches hermetic-first testing discipline. The v2-oracle conflict below still needs correction because it affects whether one of the new gates can remain executable at R3 close.

1. LOCKED DESIGN DECISIONS — Finding

Finding — v2 retirement gate conflicts with new lens parity demo gate. The plan keeps the already-declared v2 retirement gate v2_oracle_no_remaining_test_consumers at docs/r3-program-plan.md:50, but then adds a required lens_behavioral_parity_demonstration gate that “matches v2 oracle” at docs/r3-program-plan.md:164; the same v2-oracle-dependent demo is also added to canonical acceptance in docs/r3-structure.md:159. Those two gates cannot both be live R3-close TestClaims unless the parity demo uses frozen/generated parity receipts rather than the v2 oracle itself. As written, the PR reintroduces a v2 test consumer into the same close set that requires no remaining v2 oracle consumers, so the locked “v2 fully retired” decision is internally contradicted.

1. TRACKED vs UNTRACKED DEBT — Finding

Finding — bridge-inventory scaffold is declared authoritative before it has rows. The authority hierarchy says the audit doc is “Authoritative for what bridges exist now” at docs/r3-program-plan.md:14, but the audit doc’s actual Class A/B/C/D/E/F/G sections are placeholders such as [Mgr canvas populates rows] at docs/audit/r3-debt-sweep-2026-05-06.md:41, docs/audit/r3-debt-sweep-2026-05-06.md:47, and docs/audit/r3-debt-sweep-2026-05-06.md:53. The plan also says Phase 3 will populate verified counts “before plan PR opens” at docs/r3-program-plan.md:375, while the same document states the PR is already open at docs/r3-program-plan.md:3. This leaves the bridge inventory in an unlanded scaffold state while simultaneously making it the current authority for “what bridges exist now”; either the authority claim should be downgraded to framework-only, or the per-row inventory needs to land before this becomes the single source of truth.

3. Verdict

REQUEST_CHANGES

The direction is strong, and the PR does real work to consolidate R3 close criteria, but the current docs contain authority-level contradictions: canvas/status state is stale inside the “live authority,” the v2-retirement gate conflicts with a new v2-oracle-dependent demo, and the bridge inventory is named authoritative before it is populated. Those are documentation changes, but they are load-bearing program-control docs, so they need to be made internally consistent before merge.

[briansrls]

openai-pro 3 findings absorbed — sha `9f0dfaffa`

Per openai-pro REQUEST_CHANGES on sha d93fa019. All 3 valid at HEAD; structural fixes.

F1 (live-state currency — §9.2 stale completion counts) — fixed

§9.2 line 596 still said "incomplete pending 4 canvas responses (Substrate / Evaluator / PB / Debt-Paydown)" but all 4 absorbed. Stale state in live authority.

Fix: §9.2 reframed — "All 8 of 8 reviewers complete; estimate not blocked on canvas-pending state. Re-estimate as standing escalations resolve (Q-Lens-Behavioral-Parity-R3-Closeability scope-calibration is highest-leverage timeline driver)."

F2 (v2-oracle conflict with parity demo) — fixed (substantive)

lens_behavioral_parity_demonstration said "matches v2 oracle" — but v2_oracle_no_remaining_test_consumers gate forbids live v2 consumers. Two contradictory gates.

Fix: both sites (plan §1.6 + r3-structure.md §"Acceptance") now say "matches frozen v2-oracle cementing-test snapshot" — snapshot captured pre-v2-retirement; demo at R3 close consumes frozen receipt, NOT live v2 oracle. Per r3-structure.md T-Lens-Behavioral-Parity row "cementing test against v2 oracle on same source." Preserves no-v2-consumer gate.

F3 (bridge-inventory authority before populated) — fixed

§"Authority hierarchy" said audit doc "Authoritative for what bridges exist now" but Class A-G sections still carry [Mgr canvas populates rows] placeholders. Authority claim too strong.

Fix: §"Authority hierarchy" downgraded to two-tier explicit:

• Framework-authority LANDED: §1 schema + §3 rubric + §3.A grandfathering + §4 anticipation discipline
• Per-row inventory NOT YET authoritative: pending Phase 3 compile from PR docs(audit): R3 debt sweep framework draft (Phase 1) — gunbc#828 dispatch #1804 comment-thread Phase 2 deliverables

Pattern recognition

3rd substantive openai-pro find that wasn't caught by other reviewers — pattern is fresh-eyes consistency-checking across iteratively-evolved docs. Cross-doc + within-doc drift after rapid absorption rounds.

PR #1808 currently sha `9f0dfaffa`; 35 commits. All Director-disposition'd 6 standing escalations + 3 PM follow-ups remain.

Docs-only PR — three new markdown files under docs/. No code, no substrate, no tests touched.

Verdict: APPROVE — docs-only addition (R3 program plan + debt sweep audit + structure note). Nothing in this diff touches invariants, modeling substrate, Rust code, or tests, so the modeling/coding/testing rubrics don't apply. No findings.

1. Story of the diff

This PR is a docs-only authority consolidation for R3 close. It adds an R3 debt-sweep framework that classifies bridge/debt surfaces A–G, defines GREEN/YELLOW/RED/STRUCTURAL handling, and adds a going-forward PR-authoring contract for hand-Rust/debt introductions. It also adds docs/r3-program-plan.md as the forward-looking dependency graph from current state to R3 close: the plan declares the 75-gate closure set, separates “declaration” from “consumer landed,” maps substrate-gap classes to lane work, and centralizes open RED/YELLOW escalations. Finally, it updates docs/r3-structure.md so the architectural archive has the newly declared Pattern-A executable gates, substrate-gap gates, demonstration gates, and PR-authoring-discipline gate.

The load-bearing mechanism is single-authority coordination: r3-structure.md is supposed to remain canonical for what R3 is, the debt-sweep doc for bridge inventory/rubric, and the program plan for current path/escalation state. Most of the diff is explicitly trying to avoid textual enforcement bridges by marking new gates as DECLARED-only until consumers land, but there are still a few internal contradictions in the newly added authority text that need cleanup before this can safely serve as the live plan.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation)

N/A — this diff does not add or modify .dag substrate types or Dag-resident Rust structures. It names future substrate carriers and gate criteria, for example MachineConstraint<C> in docs/r3-program-plan.md:314, but those are planning declarations rather than landed substrate model changes.

2. INVARIANTS.md + modeling-discipline.md

Finding — BLOCKING, P2 single-authority / P1 documentation-describes-live-state. The LensProducer demonstration gate has two different authoritative names. The plan says the PB review fix was to reframe the gate from lens_producer_retirement_demonstration to lens_producer_retirement_executable_witness: docs/r3-program-plan.md:803 says “Fix: §1.6 row reframed from lens_producer_retirement_demonstration → lens_producer_retirement_executable_witness.” The same plan’s §1.6 table uses the new name at docs/r3-program-plan.md:152. But the canonical r3-structure.md addition still declares lens_producer_retirement_demonstration at docs/r3-structure.md:152. Because these gate IDs are intended to become closure predicates, merging both names creates parallel closure authorities; downstream consumers could implement or report against the wrong gate.

Finding — BLOCKING, P1 documentation-describes-live-state. The plan’s live-state header and later sections disagree about canvas completion. docs/r3-program-plan.md:3 says Phase 2 is ongoing with “5 of 8 reviewers complete” and “3 pending (PB / Evaluator / Research PM),” while the body later says Evaluator is fully absorbed at docs/r3-program-plan.md:745, Research PM is fully absorbed at docs/r3-program-plan.md:776, PB is “final Mgr — 8 of 8 reviewers complete” at docs/r3-program-plan.md:795, and Debt-Paydown is fully absorbed at docs/r3-program-plan.md:811. There is also a stale duplicate pending PB heading at docs/r3-program-plan.md:774. Since this document calls itself the live authority for path-to-close, stale live-state summaries are not harmless prose; they tell different managers different things about what remains unabsorbed.

Finding — BLOCKING, P2 single-authority / count authority. The 75-gate composition line still does not reconcile mechanically. docs/r3-program-plan.md:84 states that the listed existing lane-gate counts equal 59, but the addends shown in that line total 56: 4 + 4 + 6 + 1 + 1 + 8 + 4 + 2 + 6 + 4 + 2 + 10 + 4 + 3 = 56. Either three lane gates are omitted from the composition text, or the 59/75 total is wrong. Because this PR is adding the canonical closure-gate count, the count proof needs to be auditable from the line that declares it.

3. CODING.md

N/A — no Rust implementation code, interfaces, helper placement, error shapes, methods, or module structure are changed. The diff is documentation and program-plan authority only.

4. TESTING.md

Compliant — this planning PR does not add executable tests, and it honestly labels the newly declared gates as not yet load-bearing. docs/r3-program-plan.md:105 says the 75 gates are “DECLARED” and “NOT YET load-bearing closure predicates,” and docs/r3-program-plan.md:124 scopes this PR to “planning + declaration substrate” with consumer authoring in subsequent lane PRs. That is the right test posture for a plan doc, provided the authority contradictions above are fixed.

5. LOCKED DESIGN DECISIONS

N/A — the diff references design docs and r3-structure.md, but it does not edit a locked design document or silently diverge from a locked design decision in code. The material changes are new planning/acceptance declarations.

6. TRACKED vs UNTRACKED DEBT

Compliant with caveat from findings above — the new scaffolds are mostly tracked rather than hidden. docs/r3-program-plan.md:103-124 explicitly introduces DECLARED / CONSUMER_LANDED / PASSING staging, docs/audit/r3-debt-sweep-2026-05-06.md:32 requires named structural dissolution triggers, and docs/r3-program-plan.md:820-868 carries a visible escalation table rather than burying open work. The caveat is that the stale status/gate-name/count contradictions above make the tracking unreliable until reconciled.

3. Verdict

REQUEST_CHANGES

The PR is directionally strong and mostly demonstrates the right discipline for a docs-only R3 authority drop, especially the DECLARATIONS-ONLY framing. I would not merge it yet because the newly declared closure authority currently has contradictory gate names, stale live-state status, and a non-reconciling gate-count proof; those are exactly the single-authority surfaces this PR is supposed to stabilize.

[briansrls]

openai-pro 3 findings triaged — 2 fixed, 1 invalid (math error)

Per openai-pro REQUEST_CHANGES on sha 98eba595.

F1 (LensProducer gate name conflict) — VALID; fixed at sha `b5de40c46`

Plan §1.6 used lens_producer_retirement_executable_witness (post-PB Mgr F3 reframe at sha `98eba595`); r3-structure.md still had lens_producer_retirement_demonstration (old). PB Mgr F3 reframe propagated to plan but not to canonical archive — exact propagation gap pattern openai-pro has been reliably catching.

Fix: r3-structure.md gate body now uses lens_producer_retirement_executable_witness matching plan §1.6. Single-authority restored.

F2 (live-state stale) — PARTIALLY VALID at HEAD; fixed at sha `b5de40c46`

§3 status header was already updated to "All 8 of 8 reviewers complete" at sha `ddfc3f84c` (before openai-pro reviewed sha `98eba595`). But stale duplicate §10.2.5 heading at line 774 ("R3 PB Mgr — pending canvas response") remained alongside the actual §10.2.5 absorption at line 795. Duplicate generated anchors per §7.4.

Fix: stale §10.2.5 heading at line 774 removed; §10.2.5 PB Mgr appears once at line 795 with full review absorption.

F3 (75-gate count proof doesn't reconcile) — INVALID; math error

Openai-pro claimed addends "4 + 4 + 6 + 1 + 1 + 8 + 4 + 2 + 6 + 4 + 2 + 10 + 4 + 3 = 56" — but actual sum is 59 (not 56).

```
$ python3 -c "print(4+4+6+1+1+8+4+2+6+4+2+10+4+3)"
59
```

The published §1.5 count math (= 59 lane gates; plus 16 added 2026-05-06 = 75 total) is correct. No fix needed; openai-pro arithmetic is off.

Net

PR #1808 currently sha `b5de40c46`; 36 commits. F1 + F2 absorbed cleanly; F3 invalid + replied with grep/math evidence.

BLOCKING (1)

Root Cause

• docs/r3-program-plan.md r3-structure lane-table gates were excluded from the §1.5 closure-ledger computation → either include those lane gates in the canonical total/Acceptance enumeration or explicitly supersede them with the new closure gates.

⚠️ One closure-ledger authority gap remains.

[briansrls]

BLOCKING: The 75-gate ledger omits existing r3-structure lane-table gates for T-E-P-Producer-Broadening, T-Lens-Behavioral-Parity, T-Tests-As-Data-Completeness, and T-Lens-Application-Surface, so R3 close can be counted green while declared lane gates remain outside the canonical closure ledger (INVARIANTS P2/P5).

[briansrls]

Codex BLOCKING (20 gate IDs omitted) — VALID; fixed on successor PR #1809 at sha `eda532ade`

This PR (#1808) already MERGED at sha `8d88dcc3` (02:42:55Z). Codex BLOCKING relayed at 02:44:17Z is VALID and substantive — fix landed on successor PR #1809.

Diagnosis

Codex correctly flagged: 75-gate ledger + r3-structure.md §"Acceptance" both omitted 20 gate IDs from 4 lanes that were declared in §"Lane structure" prose only (single-authority violation per INVARIANTS P2/P5). The 4 lanes:

• T-E-P-Producer-Broadening (3 gates): e_p_per_call_descent_evidence_full_coverage / e_p_call_pattern_lookup_authoritative / e_p_sub_value_relation_per_call_landed
• T-Lens-Behavioral-Parity (5 gates): complexity_lens_behaviorally_complete / cost_lens_behaviorally_complete / parallelism_lens_behaviorally_complete / effect_enumeration_lens_behaviorally_complete / lens_capability_register_zero_proxy_zero_stub
• T-Tests-As-Data-Completeness (4 gates): every_rust_test_ports_to_dag_or_generated / forall_exists_quantifier_substrate_landed / program_generator_carrier_landed / lens_cementing_test_discipline_complete
• T-Lens-Application-Surface (8 gates): lens_application_carrier_landed / section_ref_substrate_landed / lens_enforcement_carrier_landed / enforce_violation_routing_landed / complexity_violation_compile_error_demonstrated / crdt_cost_basis_demonstrated / memory_peak_cost_basis_demonstrated / opt_in_iteration_parallelism_via_lens_application_demonstrated

Total: 3 + 5 + 4 + 8 = 20 gate IDs missing from canonical authority.

Fix on PR #1809

Per Brian directive 2026-05-06 (chat) — feed updates through gh issues / successor PR after #1808 merge.

PR #1809 sha eda532ade:

• r3-structure.md §"Acceptance" — 4 new lane bullets added with all 20 gate IDs (matching format of other lane bullets)
• plan §1.5 count updated 75 → 95 (79 lane gates across 18 lanes + 16 new 2026-05-06 = 95)
• plan §1.7 references "all 75 gates" → "all 95 gates"
• plan §1.8 canonical ledger extended with 20 new rows (Lane B tasks #76-Compiler lowerer cleanup #95)

Single-authority restored: all 95 gates have Pass-condition body in r3-structure.md §"Acceptance" canonical authority + consolidated index in plan §1.8 ledger.

Why this matters

Codex caught a substantial completeness gap that all 8 Mgr reviews + Director re-review missed. R3 close could have been counted green while 20 declared lane gates remained outside the canonical closure ledger. This is exactly the "duplicate authority" / "incomplete authority" class the canonical ledger was meant to eliminate.

Codex BLOCKING on sha `b5de40c4` — same finding; already absorbed at sha `eda532ade` on PR #1809

Same closure-ledger authority gap as the inline relay at PR #1808 sha (now-merged). Fix landed on successor PR #1809 (#issuecomment-4384715648).

Verification at HEAD

```

4
```

All 4 representative gate IDs (one from each missing lane) now present in r3-structure.md §"Acceptance" + plan §1.8 ledger. Total: 75 → 95 gates.

PR #1809 sha `eda532ade` carries the fix. If codex re-reviews PR #1809, this finding should not re-fire.
