docs: T-4 lane closeout — T-4.14 PTX ratified; dispatch §5 +#3338 by briansrls · Pull Request #3365 · gunb-ai/gunbc

briansrls · 2026-05-19T04:14:51Z

Summary

Ratify the T-4.14 modeling fork in src/v4/TASKS.md: PTX path is TASKS-authoritative (cross-ref ptx.dag header + DECISIONS L-3), CUDA-C++ extension called out as rejected fork.
Update docs/briefs/r4-program-dispatch-plan.md §5 Fresh extdeps row: record merged fix-language-files #3338 while T-29 cpp.dag fact-bundle forward reconcile #3277 remains OPEN for cpp forward-reconcile.

Single commit df9baaebe — publishes the citation spine hash for downstream probe work (e.g. T-4.14 ptx Wave-0) without coupling to substrate .dag changes.

Test plan

Doc-only change; reviewed diff for TASKS/DECISIONS alignment and dispatch table wording.

BLOCKING (1)

Root Cause

src/v4/TASKS.md T-4.14 closeout was recorded in the task detail and ptx.dag header, but the status/dispatch rows were not propagated or explicitly scoped as “path ratified only” → update the canonical status/dispatch wording or narrow the PASS claim.

⚠️ One task-state inconsistency needs to be reconciled before this closeout doc is reliable.

 #### T-4.14: `extdeps/languages/ptx.dag` (CUDA)
 - **Stress axis**: the **SIMT data-parallel execution model** vs the 5 L1 behaviors — the IN-B bet again (like Verilog's concurrency, but data-parallel). A needed 6th `Parallel`/`Kernel` behavior = C1 escalation, by design caught early.
- **Fork (PROPOSED — confirm)**: model **PTX** (the spec'd IR — clean, general, captures SIMT directly, parallel to llvm_ir; recommended) vs CUDA-C++ as a `cpp.dag` extension (entangled; the C++ surface is not where the stress is).
+- **PTX path (operator-ratified / evidenced):** model **PTX** (the spec'd IR — clean, general, captures SIMT directly, parallel to `llvm_ir.dag`). The CUDA-C++-as-`cpp.dag` extension alternative is the **rejected** fork (entangled; the C++ surface is not where the stress is). Probe status: `extdeps/languages/ptx.dag` header records **T-4.14 PASS (IN-B)** — same posture as **DECISIONS.md L-3** (PTX, not CUDA-C++).

Re: blocking review (TASKS vs dispatch / P2)

Verified: docs/briefs/r4-program-dispatch-plan.md §2 had T-4.14 as NOT STARTED while src/v4/TASKS.md cited the ptx.dag header PASS—two senses of “state” without an explicit bridge.

Fix pushed (3fb94ac80):

§2 Status (derived) for T-4.14 is now LANDED (v4 T-4.14: model extdeps/languages/ptx.dag — SIMT-as-5-behaviors (B2-OMNI + IN-B probe, no STOP) #3170 + D2-impact de-prose: verilog/llvm_ir/ptx + std integer/float — terse headers, archive, strict_deprose_dag.py #3229 de-prose, same receipt shape as T-4.12), Blocked-on LANDED; the folded “T-4-mgr staleness correction” footnote now includes T-4.14 (v4 T-4.14: model extdeps/languages/ptx.dag — SIMT-as-5-behaviors (B2-OMNI + IN-B probe, no STOP) #3170) with T-4.10/T-4.12; §5 Fresh: extdeps/T-4 Wave-0 cell lists T-4.10/T-4.12/T-4.14 LANDED.
TASKS.md T-4.14 bullet now separates IN-B probe receipt (substrate header, aligned with DECISIONS.md L-3) from derived scheduling, pointing to §2 as the ledger authority and noting LANDED does not erase every Scope: L tail (same rework-obligation posture as the T-4.12 row note).

Re: prior dashboard APPROVE (cursor/codex)

Re-checked src/v4/extdeps/languages/ptx.dag line 5 and DECISIONS.md L-3 after the edit; still doc-only / planning authority.

Re: codex APPROVE (review 14638 / dashboard artifact)

Verified on PR HEAD 3fb94ac80 against the cited lines:

docs/briefs/r4-program-dispatch-plan.md:94 — T-4.14 row is LANDED (v4 T-4.14: model extdeps/languages/ptx.dag — SIMT-as-5-behaviors (B2-OMNI + IN-B probe, no STOP) #3170 + D2-impact de-prose: verilog/llvm_ir/ptx + std integer/float — terse headers, archive, strict_deprose_dag.py #3229 de-prose) with the same pre-D2-reversal canonical path / rework-obligation note pattern as T-4.10 / T-4.12 sibling rows.
src/v4/TASKS.md:700 — PTX fork language matches the existing substrate receipt in src/v4/extdeps/languages/ptx.dag:5 (// Status: T-4.14 PASS (IN-B).) and explicitly defers derived status to §2 (no stale PROPOSED fork text remains in TASKS).

No further code or doc edits warranted from this verification pass.

Findings: None to implement. The tree matches the review narrative: ptx.dag keeps PASS (IN-B) / L-3 authority in TASKS + dispatch §2 while the carrier file uses a domain-neutral Scope/Status/Ledger header plus Ledger anchor: coproduct provenance lines; process.dag scaffold comments now point staging at DECISIONS.md OS-1 instead of vague trigger strings.

BLOCKING (2)

Root Cause

scripts/strict_deprose_dag.py The PR conflates DECISIONS ledger provenance with the required in-file 🟢/🟡/🔴 classification tag → keep domain-neutral status in headers/docs, but restore coproduct dissolution tags and remove the PTX ledger-anchor exemption.

⚠️ The task-state reconciliation is fixed, but the PR now strips required substrate coproduct classification tags.

Re: inline review ptx.dag:20 (codex BLOCKING — Practice 4 / Part 6 classification)

Verified on the prior head: line 20 had been changed to a Ledger anchor: one-liner, which does drop the required 🟢 coproduct dissolution Practice-4 face on each live sum carrier.

Fix (pushed): ff00607b3 restores // 🟢 coproduct dissolution — DECISIONS.md Part 6 · CP-3229-GREEN-TERMINAL. immediately above every PTX sum type in src/v4/extdeps/languages/ptx.dag (including line 20 / ParamScope). The file header stays domain-neutral (Scope/Status without process-axis PASS tags); the header // Ledger: line is back to the canonical DECISIONS.md Part 6 (PR #3229): … form so strict_deprose_dag.py --check stays authoritative.

scripts/strict_deprose_dag.py: removed the PTX Ledger anchor strip/inject/format_coproduct_tag exemption so classification tags are always the emoji + coproduct dissolution form again. process.dag OS-1 sums again use 🟡 coproduct dissolution — DECISIONS.md OS-1.

python3 scripts/strict_deprose_dag.py --check → OK locally before push.

L47 (above Termination): // 🟡 coproduct dissolution — DECISIONS.md OS-1

The prior Ledger anchor: substitution is gone; both substrate sums again carry the Practice 4 / Part 6 in-file 🟡 coproduct dissolution classification (not ledger-only anchors).

This landed in ff00607b3 together with the PTX carrier tag restoration; no additional commit needed for this thread.

Findings in the artifact: None actionable (verdict APPROVE). I re-checked the changed surface against that narrative:

ptx.dag: Domain-neutral Scope/Status header + canonical // Ledger: DECISIONS.md Part 6 (PR #3229): … line; every live sum carrier still has the required 🟢 coproduct dissolution — DECISIONS.md Part 6 · CP-3229-GREEN-TERMINAL. one-liner (Practice 4 / Part 6 classification), not ledger-only anchors.
process.dag: Termination / CaptureSource use 🟡 coproduct dissolution — DECISIONS.md OS-1; scaffold comments keep OS-1 as the explicit staging pointer (no vague trigger string).
Dispatch / TASKS: T-4.14 row still frames LANDED as dispatch/state bookkeeping (not “every Scope:L tail dissolved”), consistent with the review text and the folded footnotes in r4-program-dispatch-plan.md.

Fix commit: Not required — the APPROVE stands on inspection.

Merge readiness (re-check on this SHA):

mergeable: MERGEABLE · mergeStateStatus: CLEAN
CI: green on the workflow run tied to this head (fmt / affected / ci / v4 SUCCESS per gh pr view at verification time)
REQUEST_CHANGES: none from GitHub review API on the latest stored reviews (note: the newest GitHub-posted api-review body in the list is still keyed to cb1ff09d; a fresh ff00607b scheduled receipt may appear asynchronously after CI — treat this dashboard APPROVE as the head-correct signal unless your gate requires the GitHub comment to exist).
≥2 distinct api-review providers @ ff00607b: This item is codex-only in the relay; satisfy openai-pro + codex (or your org’s second provider) via the usual scheduled / manual api-review path if the merge gate requires two GitHub artifacts on the exact OID.

Re: claude/claude-opus-4-7 review (2026-05-19, artifact /api/reviews/14947) — verified against HEAD ff00607b385fbf5dbbd59da1600ecccb81605f5e

Verdict alignment: APPROVE stands on inspection — domain-neutral ptx.dag / process.dag headers, process-axis completion language carried in TASKS + dispatch + DECISIONS (L-3), and §5 / #3338 bookkeeping read coherently end-to-end.

Artifact precision (minor): Calling this “docs/comments-only” and “no substrate changes” is slightly loose for the actual diff. The PR does touch v4 substrate paths src/v4/extdeps/languages/ptx.dag and src/v4/extdeps/process.dag — but only the comment / header / Practice-4 coproduct one-liner layer (no edits to sum shapes, fields, or imports as modeling carriers). It also includes scripts/strict_deprose_dag.py (tooling allowlist / --check alignment), which is not Rust compiler source but is outside “docs-only”. There is no *.rs seed change in the PR file list, so the P5 / hand-Rust framing in the review still holds.

Fix commit: Not required — no defect identified in the review text.

Merge readiness (re-check):

Providers: Dashboard now has claude APPROVE (this item) plus the prior codex APPROVE artifact — two distinct providers on the relay path (org preference for openai-pro weight is orthogonal unless your gate mandates that specific provider).
mergeable: MERGEABLE · mergeStateStatus: CLEAN
CI: green on this head for fmt / affected / ci / v4 (SUCCESS in gh pr view rollup at verification time).
Merge: Not running gh pr merge (operator merges manually). Stopping work on this PR unless new CI/review deltas land.

Re: codex scheduled review (sha:ff00607b, 2026-05-19) — verified

Findings: None to implement — review ends “no blocking concerns” / effective APPROVE for the mixed docs + .dag comment/header + strict_deprose_dag.py slice it inspected.

Cross-check vs current PR head (a16f1f4c77b9bdc7889cd66cfeaec45a9726ee1e):

ff00607b is an ancestor of the current head (merge-base = ff00607b).
On the T-4.14 closeout paths (ptx.dag, process.dag, strict_deprose_dag.py, r4-program-dispatch-plan.md, extdeps-t4-lane-closeout-receipt.md) there is no diff from ff00607b → current head — codex’s PTX header / 🟢 dissolution tags / dispatch L-3 / LANDED bookkeeping caveat narrative still matches the tree.
The only TASKS.md delta since ff00607b on this branch is an unrelated merge-from-main lens-application bullet (T-23 / EnforcedApplication wording), not the T-4.14 block.

Local tooling: python3 scripts/strict_deprose_dag.py --check → OK on the checked-out PR head.

Merge readiness (re-check):

Codex: this artifact is a second scheduled codex receipt keyed exactly to ff00607b (good SHA parity for that commit).
mergeable / mergeStateStatus: were UNKNOWN at gh pr view time (common right after a origin/main merge onto the PR — GitHub recomputes); re-poll in the UI / CLI before treating as CLEAN.
CI rollup: shows a mix of SKIPPED entries tied to a newer run id plus a prior run (26120056460) with fmt / affected / ci / v4 = SUCCESS — treat green as established for the last full non-skipped matrix, and wait for the post-merge run to finish if you need an all-green row on the latest event.
≥2 providers: still satisfied by claude + codex APPROVE paths from earlier dashboard items plus this codex receipt (provider diversity vs openai-pro remains per org gate).
Merge: not running gh pr merge here (operator merges manually).
