docs(briefs): R3 Cluster M dispatch briefs (Task 2 per Director γ-hybrid ratification)

[briansrls]

Summary

Per Director ratification at gunbc#846 #issuecomment-4412309986: Task 2 (3 dispatch briefs per (γ) hybrid).

3 light-touch dispatch briefs authored per Director's guidance ("Brief format: tight (the substrate work is the heavy authoring; dispatch briefs are light coordination). Sequencing-plan doc carries the structural authority; briefs cite-and-execute"):

Brief	Owner Mgr	Phase
r3-cluster-m-dispatch-substrate-canvas-asks-2026-05-09.md	Substrate Mgr (warm-wolf-698 #2068)	1 — #85 + #86 substrate canvases (parallel)
r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md	Verification Mgr (wise-bear-525 #2075)	2 — #87 cementing-test discipline
r3-cluster-m-dispatch-verification-bulkport-84-2026-05-09.md	Verification Mgr (wise-bear-525 #2075)	3 — #84 bulk-port coordinator (strict zero, no closure-allowed exceptions)

Sequencing chain

Phase 1 (Substrate, parallel) → Phase 2 (Verification discipline) → Phase 3 (Verification bulk-port coordinator). Each phase brief names its dispatch trigger + receipt; structural authority at docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md.

Key Director-locked dispositions cited

• (γ) hybrid dispatch shape (Director Ask 1)
• Substrate Mgr standing authority for canvas drafting (Director Ask 2)
• Verification Mgr coordinator for Phase 3 (Director Ask 3)
• Strict-zero close-condition for Implement SDLC pipeline: worker dispatch, stage handlers, and integration tests #84 — no Director-allocated exception fold; bulk-port scope = all 102 entries; testgen must cover (Director Ask 4)

Authority + parents

Cites Director ratification at gunbc#846 #issuecomment-4412309986 + Cluster M sequencing plan at PR #2361. Does not restate gate Pass-conditions or sequencing structure.

Test plan

• No code changes — docs-only briefs
• All 3 briefs cite parent authority docs (does not restate)
• Cite-and-execute pattern per Director "tight format" guidance

BLOCKING (4)

Root Cause

• docs/briefs/r3-cluster-m-dispatch-substrate-canvas-asks-2026-05-09.md Cluster M dispatch was authored against unlanded sequencing/velocity artifacts → include those artifacts before these briefs or point to existing repo authorities.
• docs/briefs/r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md The split brief still relies on a missing predecessor brief → retarget #87 to docs/design-tests-as-data-completeness.md/the readiness audit or land the predecessor in the stack first.
• docs/briefs/r3-cluster-m-dispatch-verification-bulkport-84-2026-05-09.md The brief freezes velocity-audit prose as the count authority → name the full live SG-0 test partition and let sg0_census_test.rs provide the number.
• docs/briefs/r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md Phase 2 reused the Pattern-A snapshot precedent as generic cementing shape → preserve the cementing predicate authority from docs/design-tests-as-data-completeness.md §5.

Non-blocking — Strengths

• docs/briefs/r3-cluster-m-dispatch-verification-bulkport-84-2026-05-09.md The strict-zero close condition matches the THESIS/ROADMAP tests-as-data target; the concern is the duplicated count and missing authority wiring.

ROADMAP — Verified

• T-Tests-As-Data-Completeness: docs/r3-structure.md and docs/design-tests-as-data-completeness.md verify strict zero EXPECTED_HAND_AUTHORED_TEST closure as the right target.

⚠️ The dispatch shape is directionally aligned, but the briefs need live authorities and census/predicate wiring fixed before they can safely drive workers.

[briansrls]

BLOCKING: This cites r3-v-tests-as-data-v1-worker.md as an existing HEAD substrate-of-truth, but that file is absent, leaving #87 without a live substantive authority (INVARIANTS P1).

Cluster M dispatch brief cascade fix at sha 7fcd32bef

Cross-PR cascade fix from codex BLOCKING on PR #2361 sha c6c3fb96 (which BLOCKED on the sequencing plan §3 reopening carrier-shape questions despite locked design resolving them).

The substrate-canvas-asks dispatch brief in THIS PR (#2362) had the same anti-pattern: framed as "Substrate Canvas Dispatch Asks" + "Surface for Director ratification" sub-bullets that duplicated the locked design's canonical carrier definitions in docs/design-tests-as-data-completeness.md §2.1 + §2.2.

Fix at 7fcd32bef

Comprehensive rewrite of docs/briefs/r3-cluster-m-dispatch-substrate-canvas-asks-2026-05-09.md:

• Title: "Substrate Canvas Dispatch Asks" → "Substrate Carrier Landing Asks"
• §0 Scope: lists specific carriers (Quantifier + QuantifiedTestClaim + ProgramGenerator) instead of generic "substrate canvas authoring"
• §1 NEW Authority correction: cites codex BLOCKING + locked-design §1 ("no Director ratification required before lane dispatch") + INVARIANTS P2 single-authority
• §2 Dispatch disposition: pattern explicitly distinguishes "substrate-shape canvases for novel substrate (e.g., T-WAD Slice 2)" from "migration / locked-design carrier landings dispatch directly"
• §3 Substantive guidance: removed "surface for Director ratification" bullets; replaced with verbatim locked design carrier shapes (Quantifier closed sum; QuantifiedTestClaim/ProgramGenerator Rust signatures). Worker scope cites locked design §2.1/§2.2 directly.
• §4 NEW STOP-and-PING posture: if unexpected shape question arises during landing, surface via Substrate Mgr inbox (per feedback_construction_over_ratchets) rather than authoring canvas mid-port

Single canonical authority restored

Locked design docs/design-tests-as-data-completeness.md §2.1/§2.2 owns Quantifier/QuantifiedTestClaim/ProgramGenerator shape; this brief owns dispatch coordination only.

Cross-PR alignment

PR #2361 sha 697a12570 has the parallel fix on the sequencing plan; this PR's brief is now consistent with that.

PR #2362 codex BLOCKING (4) addressed at sha 602797891

Codex review on sha a88e816e flagged 4 inline BLOCKING comments. All addressed.

BLOCKING #1 — sequencing plan path absent (in-flight authority)

Verified: docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md is in-flight on concurrent PR #2361 (not on main yet). Same in-flight authority pattern as PR #2363.

Fix: each brief's authority line now notes "in-flight via concurrent PR #2361" + "this brief is the dispatch overlay — substantive content here is self-contained and grounded in [locked-design / live-ledger] authorities below." Self-containment preserved; no merge-order trap.

BLOCKING #2 — r3-v-tests-as-data-v1-worker.md absent

Refuted (tree-visibility false positive):

$ git ls-tree origin/main -- docs/briefs/r3-v-tests-as-data-v1-worker.md
100644 blob 4ff9abcb1b8bae3d06308212de5652ac1d514621	docs/briefs/r3-v-tests-as-data-v1-worker.md

File exists on main with valid blob hash. Fix at 602797891 adds explicit git ls-tree cite to discipline-87 brief §1 + locked-design authority §C5.

BLOCKING #3 — "102" hardcoding duplicates SG-0 census authority

Real finding. Bulkport-84 brief said "all 102 entries" duplicating live count.

Fix at 602797891: scope reframed to "all entries in EXPECTED_HAND_AUTHORED_TEST at PR-merge time (live authority: src/v3/compiler/tests/integration/sg0_census_test.rs; count is wc -l-derivable from the array literal — not hardcoded here to avoid duplicate-authority drift)."

BLOCKING #4 — wrong cementing predicate ( vs /)

Real finding. Locked design docs/design-tests-as-data-completeness.md §C5 row says cementing v2-oracle ports use DifferentialEquals or LensOutputEquals (same-source comparison axis). My brief specified frozen BinaryDimensionReportEquals snapshot — wrong predicate axis (BinaryDimensionReportEquals is for Pattern-A DimensionReport comparisons in TC1/TC2/TC3 family).

Fix at 602797891: discipline-87 brief §3 first-migration target predicate corrected to "same-source v2-vs-v3 comparison via DifferentialEquals or LensOutputEquals predicate (per locked design §C5)" + clarification of why BinaryDimensionReportEquals is the wrong predicate axis.

Cross-PR alignment

PR #2361 sha 697a12570 has the parallel locked-design citations on the sequencing plan (Quantifier/QuantifiedTestClaim/ProgramGenerator carriers per design §2.1/§2.2); this PR's briefs now consistent.

11 insertions / 9 deletions across 3 briefs.

BLOCKING (4)

Root Cause

• docs/briefs/r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md Missing predecessor brief remained as #87 substrate-of-truth → land that brief before this PR or make docs/design-tests-as-data-completeness.md plus this brief the full live authority.
• docs/briefs/r3-cluster-m-dispatch-substrate-canvas-asks-2026-05-09.md Phase 1 was split by gate titles instead of the full locked carrier set → assign ProgramShape and SuiteClaim in the Phase 1 worker scope and receipt.
• docs/briefs/r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md Property-based carrier work and cementing-register coverage were conflated → keep #87 on the locked cementing register/TestClaim path and reserve ProgramGenerator for program-family claims.
• docs/briefs/r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md Old canvas-ratification sequencing survived the authority correction → rewrite #87 trigger around locked design plus both carrier-shape landings.

Non-blocking — Strengths

• docs/briefs/r3-cluster-m-dispatch-verification-bulkport-84-2026-05-09.md Strict-zero closure now reads from EXPECTED_HAND_AUTHORED_TEST at merge time instead of duplicating the count.
• docs/briefs/r3-cluster-m-dispatch-verification-discipline-87-2026-05-09.md The first migration predicate is now aligned with the locked C5 same-source v2-oracle axis.

ROADMAP — Verified

• T-Tests-As-Data-Completeness: docs/r3-structure.md and docs/design-tests-as-data-completeness.md verify the four gates and strict zero EXPECTED_HAND_AUTHORED_TEST closure.

⚠️ The strict-zero and predicate fixes are good, but the #87 authority and Phase 1/#87 substrate dispatch still need live locked-design wiring before these briefs can drive workers.

[briansrls]

BLOCKING: The added "Verified live on main" claim is false in the repo because docs/briefs/r3-v-tests-as-data-v1-worker.md is absent, so #87 still depends on a non-live authority (INVARIANTS P1 documentation describes live state).

[briansrls]

BLOCKING: The Phase 1 receipt omits ProgramShape and SuiteClaim even though the locked design's carrier landing authors both in src/v3/std/verification.dag, so workers can close #85/#86 without the full substrate surface (INVARIANTS P2 boundary sufficiency).

[briansrls]

BLOCKING: This makes cementing coverage use Quantifier/QuantifiedTestClaim/ProgramGenerator, but the locked design makes cementing a LensRegistry projection ratchet with DifferentialEquals/LensOutputEquals TestClaims; ProgramGenerator ranges over ProgramShape, not lens rows (P1 modeling faithfulness).

[briansrls]

BLOCKING: The #87 trigger still dispatches on partial substrate-canvas Director ratification even though the locked design says no Director ratification is required and #87 consumes both #85/#86 carrier shapes (INVARIANTS P2 boundary discipline).

[briansrls]

BLOCKING (relay) — already addressed at sha 602797891

Same finding from prior dashboard relay. Relay arrived after fix.

Per #issuecomment-4412812079: BLOCKING #1 (sequencing plan path absent / in-flight authority) addressed at sha 602797891. Each brief's authority line now notes "in-flight via concurrent PR #2361; this brief is the dispatch overlay — substantive content here is self-contained and grounded in [locked-design / live-ledger] authorities below."

Verification at HEAD (602797891):

$ grep -n "in-flight" docs/briefs/r3-cluster-m-dispatch-substrate-canvas-asks-2026-05-09.md
4:...lives at docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md §3 (in-flight via concurrent PR #2361; this brief is the dispatch overlay — substantive content here is self-contained and grounded in locked-design authority docs/design-tests-as-data-completeness.md §2.1/§2.2 cited below)...

Substantive content of brief is self-contained:

• §3 cites locked design docs/design-tests-as-data-completeness.md §2.1 + §2.2 with verbatim carrier shapes
• §1 Authority correction explains the duplicate-authority anti-pattern that was fixed
• §4 STOP-and-PING posture replaces canvas-tier ratification framing

No merge-order trap on the in-flight sequencing-plan path; brief stands independently.

Same finding from prior dashboard relay (BLOCKING #3 in the codex review batch). Relay arrived after fix.

Verification at HEAD (602797891) — line 18 (per relay's pinpoint) now reads:

**Bulk-port scope = all entries in `EXPECTED_HAND_AUTHORED_TEST`** at PR-merge time (live authority: [`src/v3/compiler/tests/integration/sg0_census_test.rs`](...); count is `wc -l`-derivable from the array literal — **not hardcoded here** to avoid duplicate-authority drift). This is post #85/#86/#87 substrate landing.

"102" hardcoding removed; live SG-0 census file cited as authority instead. Workers will read scope from sg0_census_test.rs at PR-merge time, not from a stale hardcoded count.

BinaryDimensionReportEquals is for Pattern-A DimensionReport comparisons (TC1/TC2/TC3 family), NOT for cementing — different predicate axis.

Predicate corrected from BinaryDimensionReportEquals to DifferentialEquals/LensOutputEquals per locked design §C5. Explicit explanation of why BinaryDimensionReportEquals is wrong axis (Pattern-A DimensionReport, not cementing).

Codex review BLOCKING (4) on 60279789 — 2 substantive findings need follow-up PR (this PR merged 15:14:41Z)

PR #2362 merged at 15:14:41Z (squash commit). Codex review on sha 60279789 arrived after merge but flagged 2 substantive bugs that warrant a follow-up correction PR. Findings analysis:

BLOCKING #1 — r3-v-tests-as-data-v1-worker.md predecessor brief

Partially tree-visibility false positive: file EXISTS on main (verified earlier via git ls-tree origin/main → blob 4ff9abcb1b8b). But codex's underlying point — locked design + this brief should be the full live authority — is a reasonable framing improvement. Soft non-blocking; can address in follow-up.

BLOCKING #2 — Phase 1 carrier set incomplete (REAL bug)

Locked design docs/design-tests-as-data-completeness.md §6 line 344 explicitly says Phase 1 substrate carriers landing introduces 5 carriers:

"Author ProgramGenerator, ProgramShape, Quantifier, QuantifiedTestClaim, SuiteClaim extensions to src/v3/std/verification.dag per §2."

My briefs only mentioned 3 of 5 (Quantifier, QuantifiedTestClaim, ProgramGenerator); missed ProgramShape (used by ProgramGenerator body) + SuiteClaim (Quantified variant for QuantifiedTestClaim). Real bug; follow-up required.

BLOCKING #3 — #87 conflated with property-based carrier work (REAL bug)

Discipline-87 brief said "every .dag lens has at least one cementing test in .dag form using #85 Quantifier + QuantifiedTestClaim carriers + #86 ProgramGenerator carrier" — but cementing tests use DifferentialEquals/LensOutputEquals (per locked design §C5), NOT property-based generators. #87 is orthogonal to #85/#86. Real bug; follow-up required.

BLOCKING #4 — Old canvas-ratification sequencing in #87 trigger (REAL bug, cascade of #3)

Trigger says "Verification Mgr dispatches #87 discipline-authoring on Phase 1 partial-land — i.e., once at least one of #85/#86 substrate canvases has Director ratification on carrier shape" — but #87 doesn't depend on #85/#86 at all (cementing uses existing DB-15 TestClaim infrastructure). Trigger should be rewritten without the #85/#86 dependency. Real bug; follow-up required.

Strengths acknowledged

• Strict-zero closure reads from EXPECTED_HAND_AUTHORED_TEST at merge time — confirmed
• First migration predicate aligned with locked C5 same-source v2-oracle axis — confirmed (sha 602797891)

Verified

• T-Tests-As-Data-Completeness: docs/r3-structure.md and docs/design-tests-as-data-completeness.md verify the four gates and strict-zero EXPECTED_HAND_AUTHORED_TEST closure — confirmed

Follow-up plan

PR is merged; need a follow-up correction PR for findings #2 + #3 + #4 (real bugs in the merged briefs). Will author follow-up amendment if operator/Director authorize. Findings #1 is non-blocking framing improvement; can fold into the same follow-up PR.

BLOCKING (relay) — REAL bug; queued for follow-up correction PR per #issuecomment-4412858415

PR #2362 merged at 15:14:41Z; this codex inline finding arrived post-merge. Real bug confirmed (this is BLOCKING #2 from my substantive analysis):

Locked design docs/design-tests-as-data-completeness.md §6 line 344 explicitly says Phase 1 introduces 5 carriers:

"Author ProgramGenerator, ProgramShape, Quantifier, QuantifiedTestClaim, SuiteClaim extensions to src/v3/std/verification.dag per §2."

My substrate-canvas-asks brief at sha 602797891 only listed 3 of 5 (Quantifier, QuantifiedTestClaim, ProgramGenerator); missed ProgramShape (used by ProgramGenerator body) + SuiteClaim (Quantified variant for QuantifiedTestClaim).

Workers reading this brief would close #85/#86 without the full substrate surface — INVARIANTS P2 boundary sufficiency violation.

Queued for follow-up correction PR (awaiting operator authorization per #issuecomment-4412858415). Same follow-up will also address BLOCKING #3 / #4 (#87 conflation with #85/#86 dependencies; cementing uses DB-15 TestClaim infrastructure not property-based carriers).

BLOCKING (relay) — REAL bug; queued for follow-up correction PR per #issuecomment-4412858415

This is BLOCKING #3 from the substantive analysis. Confirmed real bug:

My discipline-87 brief at sha 602797891 line 35: "Discipline pattern: how every .dag lens has at least one cementing test in .dag form using #85 Quantifier + QuantifiedTestClaim carriers + #86 ProgramGenerator carrier"

Locked design says cementing is orthogonal to property-based carriers:

• §C5 cementing v2-oracle: uses DifferentialEquals / LensOutputEquals TestClaims (single-source predicates over LensRegistry rows)
• §2.1/§2.2 ProgramGenerator: ranges over List<ProgramShape> for property-based "every program" claims
• §C5 cementing rows are NOT a program-family axis — they're per-lens (LensRegistry projection ratchet)

So the conflation ("cementing uses #85/#86") is structurally wrong. Cementing uses existing DB-15 TestClaim infrastructure with the right predicate variants — no #85/#86 dependency.

P1 modeling faithfulness violation: ProgramGenerator ranging over LensRegistry rows would treat lens rows as a closed roster (the same anti-pattern flagged in lens-library-design.md §1.5 that ProgramGenerator was specifically designed to avoid).

Queued for follow-up correction PR. Plan:

• Discipline-87 brief: rewrite §3 authoring scope to use only DB-15 TestClaim infrastructure + DifferentialEquals/LensOutputEquals predicates (no Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86 references)
• Discipline-87 brief: rewrite §2 dispatch trigger to remove the "Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86 substrate canvases ratification" prerequisite (cementing doesn't depend on property-based carriers)
• Cluster M sequencing plan §4 (in PR docs(r3): PB-0 remediation program — Cluster M sequencing + §10 RED + option-(c) discipline + SG-0 tracker #2361 — already merged): same RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 framing fix needed there if present

BLOCKING (relay) — REAL bug; queued for follow-up correction PR per #issuecomment-4412858415

This is BLOCKING #4 from the substantive analysis. Confirmed real bug at line 27 of merged discipline-87 brief:

"Verification Mgr dispatches #87 discipline-authoring on Phase 1 partial-land — i.e., once at least one of #85/#86 substrate canvases has Director ratification on carrier shape (does NOT require both #85 and #86 carriers to fully land...)"

Two issues:

1. "Director ratification on carrier shape": anti-pattern. Per locked design docs/design-tests-as-data-completeness.md §1 Authority discipline: "All §8 design questions resolved in-doc per feedback_design_before_implement — no Director ratification required before lane dispatch." This applies to the whole T-Tests-As-Data-Completeness lane including RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87. Same canvas-tier-ratification anti-pattern that codex flagged on PR docs(r3): PB-0 remediation program — Cluster M sequencing + §10 RED + option-(c) discipline + SG-0 tracker #2361 sequencing plan.

2. "once at least one of Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86 substrate canvases": partially conflates layers. Per locked design §6 line 344, Phase 1 lands SuiteClaim which has Enumerated/Quantified variants. Existing TestClaims (including cementing) wrap in Enumerated(...). So RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 has a SuiteClaim-wrapper coupling to Phase 1 — but that's at the wrapper level, not at the property-based ForAll/Exists level my brief implied (per BLOCKING . #3 analysis).

Correct framing for follow-up:

• RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 discipline pattern uses existing DB-15 TestClaim infrastructure + DifferentialEquals/LensOutputEquals (per §C5)
• New TestClaim shape is SuiteClaim::Enumerated(TestClaim) after Phase 1 lands SuiteClaim — backward-compatible wrap
• RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 dispatch trigger: on Phase 1 carrier landing (not on canvas ratification — there is no canvas-tier ratification per locked design §1)

## §2. Dispatch trigger

**Authority correction 2026-05-09 (codex BLOCKING #4 on PR #2362 sha `60279789`)**: prior trigger said "once at least one of #85/#86 substrate canvases has Director ratification on carrier shape" — duplicate-authority anti-pattern (locked design §1: "no Director ratification required before lane dispatch") + wrong dependency direction (cementing is orthogonal to property-based ProgramGenerator/Quantifier per BLOCKING #3).

**Corrected trigger**: Verification Mgr dispatches #87 discipline-authoring **independently of #85/#86 dispatch**. #87 cementing uses existing DB-15 `TestClaim` infrastructure + `DifferentialEquals` / `LensOutputEquals` predicate variants (per locked design §C5)...

Both root causes addressed:

• "Director ratification on carrier shape" prerequisite removed from trigger (per locked design §1: "no Director ratification required before lane dispatch")
• "RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 consumes Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86 carrier shapes" reframed: RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 cementing uses existing DB-15 TestClaim + DifferentialEquals/LensOutputEquals (TERMINAL predicates available today on main); coupling to Phase 1 exists only at SuiteClaim wrapper level (mechanical post-Fix gist #85 wrap, backward-compatible). Property-based axis (ProgramGenerator/Quantifier) is orthogonal to cementing axis.
