docs(briefs): regen_lens audit refresh after PB dispatch (warm-ant-877)

[briansrls]

Summary

Mechanical verification + anchor refresh for PB Manager dispatch (regen_lens / BinShim readiness), docs-only — no substrate edits, no invented carrier fields.

r3-pb-regen-lens-consumer-audit.md

• Fix stale citations (SG-0 path at :237, REGEN_OUTPUTS 479-513, nine explicit [[bin]] targets including emit_method_template_projection + r1c_e_emit_gates).
• Handoff row: BinShim carrier landed — align prose with live src/v3/std/bin_shim.dag (entrypoint_name, not legacy sketch name).
• New Delta — 2026-05-06 mechanical verification table pinned to origin/main @ 194ddb7a8.

r3-pb-regen-lens-first-binshim-target-retirement-readiness.md

• Required-design-objects row: carrier verified on main; retirement still blocked on emit pattern, instance, §7.2, Item 4, §7.3.
• Dispatch-ready row (4): annotated as mechanically verified — carrier is not the active chain blocker (README-only bin_shims/; row Add SVG viz, test helpers, and makegen scaffold #1 regen_lens_main STOP unchanged).

Verification

• rg / file reads only; repro SHA in doc body.

PB Manager review (warm-ant-877 / dispatch scope)

Verdict: Direction matches the dispatch: docs-only, honest mechanical verification, no carrier-field invention, and the blocker narrative improvement is correct — `BinShim` is live on `src/v3/std/bin_shim.dag`; the retirement chain’s active gap stays instance + Item 5 emitter + §7.2 + convergence / §7.3, not “wait for carrier.”

Spot-check against current tree (this worktree):

• `EXPECTED_HAND_AUTHORED_NON_TEST` holds `regen_lens.rs` at `sg0_census_test.rs:237`; table starts `:211` — matches the PR’s anchor refresh.
• `src/v3/compiler/Cargo.toml`: 9 `[[bin]]` blocks in the cited range — matches.
• `regen.dag`: 9 `^data .*_entry: LensRegistryEntry` rows — matches the new audit table.
• `REGEN_OUTPUTS`: 25 path literals; no `regen_lens.rs` entry — matches.
• `BinShim` record fields align with the updated handoff prose (`entrypoint_name`, `description`, `entry: DeclarationRef`).

Same-PR doc consistency (recommended): `r3-pb-regen-lens-first-binshim-target-retirement-readiness.md` §Non-authority (top of file) still lists “Substrate-owned `BinShim` carrier” among what retirement waits on. The table + dispatch-ready row in this PR now say the carrier landed — consider tightening that paragraph so readers skimming only the header don’t carry a stale “carrier missing” signal.

Optional follow-up (non-blocking): In `r3-pb-regen-lens-consumer-audit.md`, the `GENERATED_FILES` / `build.rs` citation in the “Source surface” table may have line drift vs the block that builds the manifest after `REGEN_OUTPUTS`; worth re-pinning when convenient for anchor hygiene.

Otherwise LGTM for merge from PB dispatch intent.

Findings

None. The diff only updates two briefs (docs/briefs/r3-pb-regen-lens-consumer-audit.md, docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md): refreshed REGEN_OUTPUTS / SG-0 line anchors, corrects the nine-[[bin]] picture (including emit_method_template_projection), aligns the handoff table with the live BinShim record in src/v3/std/bin_shim.dag:19-23, and adds a dated mechanical verification block with an explicit origin/main pin. Spot-checks against this worktree match those claims (9 bins in Cargo.toml, 25 REGEN_OUTPUTS paths in build.rs:479-513, regen_lens.rs at sg0_census_test.rs:237, 9 LensRegistryEntry rows matching the cited rg pattern). Nothing here contradicts INVARIANTS.md / modeling-discipline (documentation is grounded in cited paths and a repro pin), and CODING.md / TESTING.md do not apply to these markdown-only edits.

Verdict

APPROVE — Narrow documentation audit refresh; factual anchors check out; no rubric violations observed in the diff.

[briansrls]

Response to PB Manager review (2026-05-06T18:03:21Z)

Same-PR doc consistency (readiness): Rewrote §Non-authority so it no longer lists “wait for Substrate-owned BinShim carrier.” It now states the carrier is already on main (src/v3/std/bin_shim.dag), lists the actual remaining gates (Item 4, dsl/std/runtime/bin_shims/ instance/regen_lens_main, emitter, §7.2, retirement PR / convergence / §7.3 per the tables below), and points readers at §Required design objects + §Dispatch-ready row — aligned with the landed-carrier rows in the same file.

Optional follow-up (consumer audit): Repinned GENERATED_FILES / build.rs in Build / packaging surfaces: REGEN_OUTPUTS literal 479-513; manifest emission that defines the static is 514-526 (loop over REGEN_OUTPUTS). Also refreshed Scope, Status, Non-overlap (Substrate Manager bullet now “carrier regressions / P1 pressure”, not “not yet on main”), and the registry row count in Source surface to 9 with the same ^data discipline as the mechanical-verification delta.

Pushed as c110e69a6 on docs/pb-regen-lens-audit-2026-05-06.

Re-checked against current docs/pb-regen-lens-audit-2026-05-06 tip (c110e69a6 — adds PB Manager consistency + GENERATED_FILES :514-526 pin on top of your SHA).

• Scope: git diff origin/main --stat is still only the two briefs named in the review; no Rust / .dag edits in the PR delta.
• Facts called out at 79073f2f: Nine [[bin]] targets (Cargo.toml:47-85), 25 REGEN_OUTPUTS strings (build.rs:479-513), regen_lens.rs on sg0_census_test.rs:237, 9 ^data .*_entry: LensRegistryEntry rows — unchanged by the follow-up commit (which tightens prose + line citations only).
• Rubric: Still documentation with file/line pins and origin/main repro — no new claims that would trip INVARIANTS / modeling discipline; no product code or tests touched.

No additional commit required for this review item; approval carries to current head.

APPROVE — Docs-only refresh of two planning briefs. Updates reflect that the BinShim substrate carrier has landed on main, refreshes line numbers (build.rs:479-513, sg0_census_test.rs:237), corrects the registry-row count (9 vs. 11 via anchored regex), and bumps the bin count (8 → 9). All claims are mechanical/verifiable and consistent across both files. No code, no invariant surface touched; no modeling-discipline concerns.

[briansrls]

Response to scheduled api-review (claude-opus-4-7, c110e69a)

Confirmed HEAD is c110e69a6 — matches the review SHA.

Diff scope: git diff 194ddb7a8..c110e69a6 --name-only is only the two briefs in the review; no Rust / .dag / invariant surface in those commits. The approval’s bullets (landed BinShim framing, build.rs:479-513, sg0_census_test.rs:237, 9 anchored registry rows, 9 [[bin]]) match the current file text on this branch.

Merge-base note (FYI, not a review defect): This branch forks 194ddb7a8 while origin/main has advanced (e.g. 419ec7be8 / #1842). GitHub’s full PR diff vs latest main will show extra paths until origin/main is merged into this branch — unrelated to the doc-only commits the bot reviewed.

No further commit needed for this approval.

Non-blocking — Strengths

• docs/briefs/r3-pb-regen-lens-consumer-audit.md The refresh stays grounded in the live BinShim carrier and preserves the remaining STOP on regen_lens_main, instance authoring, emitter work, and §7.2 equivalence.

✅ Docs-only refresh looks clean; I found no blocking concerns.

[briansrls]

Response to scheduled codex api-review (c110e69a)

Verified at current HEAD (120d79021):

• The two briefs codex scoped (r3-pb-regen-lens-consumer-audit.md, r3-pb-regen-lens-first-binshim-target-retirement-readiness.md) are byte-identical to c110e69a6 (git diff c110e69a6..HEAD -- <those paths> is empty), so the review’s “grounded carrier / STOP chain / docs-only” read still applies.
• This branch has since merged origin/main, so the PR no longer sits on a stale merge-base for integration — unrelated to your approval but relevant for merge hygiene.

No blocking issues found in review; nothing further to change for this item.

Docs-only diff updating two audit briefs to reflect the BinShim carrier landing on main and mechanical line-number/count refresh.

Verdict: APPROVE — docs-only refresh of two planning briefs; no code/substrate changes, citations look internally consistent, and the file:line updates (build.rs:479-513, sg0_census_test.rs:237, 9 bins, 9 registry rows) are framed as a dated mechanical audit. Nothing in this diff touches substrate, Rust code, or tests, so the modeling/coding/testing rubrics don't bite.

Minor exploratory note (non-blocking): one row in r3-pb-regen-lens-first-binshim-target-retirement-readiness.md table loses its trailing | after the STOP sentence — markdown renderers usually tolerate this but it's a slight inconsistency vs. the other rows.

[briansrls]

Response to scheduled api-review (fc609539, claude-opus-4-7)

Approval: Re-verified git diff origin/main...HEAD (prior to this push) remained docs-only on the two regen_lens briefs — matches the APPROVE rubric.

Minor note — fixed: In r3-pb-regen-lens-first-binshim-target-retirement-readiness.md §Required design objects, the BinShim carrier table row was missing the final column delimiter (|). Valid catch; most renderers still showed the row, but it was inconsistent with the other rows.

Commit: 9ddb0a6d5 — append closing | on that row only.

Findings: None. This diff only edits two planning briefs under docs/briefs/. It does not touch substrate types, compiler Rust, or tests, so INVARIANTS.md, docs/modeling-discipline.md, CODING.md, and TESTING.md have nothing substantive to violate here. The updates reinforce report-instead-of-invent (explicit STOP rows, no carrier-field invention) and add grounded audit notes (repro pin commit, named commands, file:line anchors)—consistent with modeling-faithfulness for documentation artifacts.

Verdict: APPROVE — Docs-only refresh with mechanically pinned facts (registry row count, [[bin]] census, build.rs / SG-0 line anchors, BinShim living in bin_shim.dag). Spot-check against the tree shows 9 anchored LensRegistryEntry rows, 9 bin targets, and regen_lens.rs cited at sg0_census_test.rs:237, matching the brief.

Exploratory observations (optional): None required; the scope is tight and the delta table improves audit reproducibility for whoever picks up the retirement work.

Spot-check (current tree):

9 ^data … LensRegistryEntry rows	rg '^data .*_entry: LensRegistryEntry' regen.dag → 9 hits
9 explicit [[bin]] targets	Cargo.toml → 9 [[bin]] blocks (:47-83)

1. Story of the diff

This PR is a docs-only refresh of the regen_lens.rs BinShim retirement audit after PB dispatch verified that the substrate BinShim carrier has already landed. The consumer audit no longer treats carrier landing as future work; it narrows the remaining handoff to BinShim instance authoring, emitter work, §7.2 equivalence, and SG-0/build manifest deltas, while pinning the refreshed mechanical facts: 9 registry rows, 9 Cargo bins, 25 REGEN_OUTPUTS, SG-0 at line 237, README-only bin_shims/, and live src/v3/std/bin_shim.dag:19-23 carrier shape at docs/briefs/r3-pb-regen-lens-consumer-audit.md:148-161. The readiness checklist makes the same correction: carrier introduction is no longer a retirement gate, but carrier-shape pressure still routes to Substrate Manager/P1 instead of letting the PB lane invent fields ad hoc at docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:23.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation). Compliant — the diff does not modify substrate files, and the docs explicitly separate the already-landed substrate carrier from PB-owned instance/emitter work: “carrier shape lives in src/v3/std/bin_shim.dag; instance / emitter / §7.2 sequencing remain PB + Substrate dispatch” at docs/briefs/r3-pb-regen-lens-consumer-audit.md:16, with carrier-shape pressure routed back to Substrate/P1 at docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:23.
2. INVARIANTS.md + modeling-discipline.md. Compliant — single authority / fail-closed planning is preserved by refusing to invent missing fields or instance rows in this audit: docs/briefs/r3-pb-regen-lens-consumer-audit.md:152 says the dispatch closes rows with “docs + mechanical audits only — no BinShim carrier-field invention, no .dag instance authoring,” and docs/briefs/r3-pb-regen-lens-consumer-audit.md:101 anchors the live carrier fields to src/v3/std/bin_shim.dag instead of restating an independent schema.
3. CODING.md. N/A — this diff changes only Markdown briefs; no Rust functions, helpers, APIs, error shapes, or implementation style surfaces are added or modified.
4. TESTING.md. N/A — no executable behavior changes. The PR records mechanical audit commands/results, but does not alter code or promote a behavior-complete claim that would require a new test in this diff.
5. LOCKED DESIGN DECISIONS. Compliant — the diff references locked PB-Runtime/BinShim design objects while making the divergence explicit: historical §4.2 name sketches are reconciled to the live entrypoint_name, description, entry: DeclarationRef carrier at docs/briefs/r3-pb-regen-lens-consumer-audit.md:101, and the retirement remains gated on §7.2 equivalence plus the later retirement PR at docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:7.
6. TRACKED vs UNTRACKED DEBT. Compliant — remaining work is bounded and assigned rather than left as vague scaffold. The readiness brief names the still-open gates: Item 5 emit pattern, regen_lens_main + instance row, §7.2, Item 4 convergence, and §7.3 disposition at docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:23; the audit also records that dsl/std/runtime/bin_shims/ is README-only with no regen_lens.dag, preserving the STOP instead of implying completion at docs/briefs/r3-pb-regen-lens-consumer-audit.md:160.

3. Verdict

APPROVE. The diff is a bounded documentation correction: it removes a stale “carrier not landed” gate, keeps the substrate/PB boundary explicit, and tracks the remaining retirement blockers with mechanical receipts rather than adding new authority. I did not find a changed line that violates the requested invariants.

Findings: None. The diff only updates two PB briefs; it does not touch substrate, compiler Rust, or tests, so modeling-practice items (new enums, boundaries, fail-closed paths) and CODING.md / TESTING.md enforcement for new code do not apply. Spot-checks against this tree match the updated audit: nine anchored LensRegistryEntry rows in regen.dag, nine [[bin]] blocks in Cargo.toml, REGEN_OUTPUTS spanning build.rs:479–512 with 25 paths and no regen_lens.rs, regen_lens.rs at sg0_census_test.rs:237, dsl/std/runtime/bin_shims/ containing only README.md, and BinShim at src/v3/std/bin_shim.dag:19–23 with entry: DeclarationRef. That supports INVARIANTS’ “documentation describes live state” intent for these edits rather than contradicting it.

Verdict: APPROVE — Narrow docs refresh: carrier-on-main narrative, corrected counts/locations, and a bounded mechanical verification section. No rubric violations observed in the diff.

1. Story of the diff

This PR refreshes two regen_lens.rs retirement planning briefs after mechanical PB dispatch verification. The first doc, r3-pb-regen-lens-consumer-audit.md, updates the audit from “waiting on future BinShim carrier” to “carrier exists; do not invent fields here,” corrects live counts and line anchors for LensRegistryEntry rows, Cargo bins, REGEN_OUTPUTS, and SG-0 census, then adds a pinned 2026-05-06 audit table showing exactly what was verified (docs/briefs/r3-pb-regen-lens-consumer-audit.md:148-161). The second doc, r3-pb-regen-lens-first-binshim-target-retirement-readiness.md, removes carrier landing as an active blocker while preserving the remaining gates: Item 4 convergence, regen_lens_main / data regen_lens_shim, emitter, §7.2 equivalence, and retirement-PR census deltas (docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:7, :77). Net effect: this is a docs-only audit refresh that narrows the remaining retirement work without authorizing implementation or .dag instance creation.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

Compliant — the diff references substrate state but does not mutate substrate types or Dag carriers; it keeps the PB docs lane from becoming substrate authority by routing carrier-shape pressure back to Substrate P1: docs/briefs/r3-pb-regen-lens-consumer-audit.md:22 says “BinShim carrier regressions + P1 if instance authoring surfaces carrier-shape pressure,” and readiness line docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:23 explicitly says “do not invent fields ad hoc from the PB lane.”

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

Compliant — P2 single-authority and P5 dissolution are handled directly: the audit replaces the hypothetical carrier-landing row with the live carrier authority at docs/briefs/r3-pb-regen-lens-consumer-audit.md:101, while the same retirement PR still owns the paired REGEN_OUTPUTS extension and SG-0 census drop at docs/briefs/r3-pb-regen-lens-consumer-audit.md:106-107. P3 fail-closed / report-instead-of-invent is also explicit: docs/briefs/r3-pb-regen-lens-consumer-audit.md:152 scopes this dispatch to “docs + mechanical audits only — no BinShim carrier-field invention, no .dag instance authoring.”

1. CODING.md.

N/A — diff is documentation-only; no Rust functions, methods, helpers, result shapes, imports, or impurity surfaces are introduced.

1. TESTING.md.

Compliant — no executable behavior changes, so no new test is required in this PR; the future behavioral proof remains explicitly gated, not silently waived. docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:7 keeps “§7.2 equivalence” and a retirement PR with “behavioral proof” in the actual retirement path, and docs/briefs/r3-pb-regen-lens-consumer-audit.md:160 records that no regen_lens.dag instance exists yet.

1. LOCKED DESIGN DECISIONS.

Compliant — the PR references locked PB-Runtime / BinShim design surfaces but makes the live-state divergence explicit instead of hiding it: docs/briefs/r3-pb-regen-lens-consumer-audit.md:101 says historical §4.2 sketches used name, while scheduled work now keys off live entrypoint_name; docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:7 preserves Item 4, emitter, §7.2, and §7.3 disposition as remaining gates.

1. TRACKED vs UNTRACKED DEBT.

Compliant — no new scaffold is introduced. The outstanding temporary states are named, bounded, and assigned: no .dag instance authoring in this dispatch (docs/briefs/r3-pb-regen-lens-consumer-audit.md:152), no regen_lens.dag present yet (docs/briefs/r3-pb-regen-lens-consumer-audit.md:160), and the retirement-chain blockers are enumerated rather than collapsed into a green checklist (docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md:7, :77).

3. Verdict

APPROVE

The diff is a clean docs-only audit refresh: it updates stale facts, keeps substrate authority in the substrate lane, and preserves the future retirement/equivalence gates instead of prematurely green-lighting regen_lens.rs deletion. I did not find a diff-line-supported invariant violation.

Findings

• docs/briefs/r3-pb-regen-lens-consumer-audit.md:102 — In the same handoff-table hunk where the carrier row is rewritten to landed on main (:101), the instance row still says “dispatched by PB on carrier landing.” That precondition is outdated next to the updated carrier narrative and edges toward the “Documentation Describes Live State” concern called out under P1 / related rules in INVARIANTS.md (single coherent story for readers). Non-blocking: tighten wording so instance dispatch is not framed as waiting on carrier landing.

Verdict: APPROVE_WITH_COMMENTS — Docs-only refresh with pinned mechanical audit, corrected counts/anchors, and carrier-on-main alignment; one leftover phrase in the instance-authoring row should be updated for consistency.

Exploratory (optional): The section title at docs/briefs/r3-pb-regen-lens-consumer-audit.md:95 still says “future BinShim carrier”; it did not change in this diff, so it is out of scope for a strict diff-grounded finding—worth a follow-up edit if you want the heading to match “carrier landed, remaining work is instance/emitter/§7.2.”

Response to scheduled api-review (composer-2, 7c877b7e)

Finding (instance row / carrier narrative): Valid — alongside the landed carrier row (L101), the instance row owner still said “dispatched … on carrier landing,” which contradicted the updated story.

Fix (pushed 615533bca):

• data regen_lens_shim row — Owner column: Reworded to PB dispatch for the dsl/std/runtime/bin_shims/ instance slice, explicitly not contingent on carrier introduction (substrate carrier already on main).
• §Handoff heading (~L95): Renamed from “future BinShim carrier …” to ## Handoff points — landed \BinShim` carrier; instance + emitter + §7.2 fixture` so the section title matches “carrier on main; remaining work is instance/emitter/§7.2” (your exploratory note — applied as the same consistency pass).

APPROVE

Diff is docs-only and the refreshed claims I spot-checked are mechanically consistent with the current tree. I verified the updated BinShim carrier status, the regen.dag registry count, Cargo bin count, REGEN_OUTPUTS anchors, and the SG-0 census anchor; nothing in the diff appears to violate the pinned invariants or the coding/testing guidance.

Response to scheduled codex api-review (615533bc)

Confirmed HEAD = 615533bca — matches the review SHA; git merge-base HEAD origin/main = 697477615 — matches metadata.

Scope: git diff origin/main...HEAD --name-only is only
docs/briefs/r3-pb-regen-lens-consumer-audit.md and
docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md — docs-only; no Rust / substrate edits in the three-dot range.

The mechanical pins in those briefs (registry row count, nine [[bin]], REGEN_OUTPUTS / SG-0 anchors, landed-BinShim narrative + handoff wording post-615533bc) remain aligned with the spot-check story in your approval; CODING.md / TESTING.md N/A for this delta.

✅ Docs-only refresh is consistent with the thesis and cited authorities; I found no blocking concerns after verifying the live BinShim carrier, registry/Cargo/build counts, and SG-0 anchors.

Response to scheduled codex api-review (615533bc)

• Reviewed commit 615533bc is on the ancestry of current HEAD (bea96e8c0); the two briefs are unchanged since 615533bc (git diff 615533bc..HEAD -- <briefs> is empty — latest tip is a merge-only integration of origin/main).
• git diff origin/main...HEAD --name-only is still only
  docs/briefs/r3-pb-regen-lens-consumer-audit.md and
  docs/briefs/r3-pb-regen-lens-first-binshim-target-retirement-readiness.md — docs-only PR delta.

Your thesis/consistency read at 615533bc still describes the files at the branch tip; no blocking follow-up from this pass.

APPROVE — Docs-only diff updating two planning briefs to reflect that the BinShim substrate carrier has landed on main, plus mechanical re-counts (9 LensRegistryEntry rows, 9 Cargo bins, line-number refresh for sg0_census_test.rs:237, build.rs:479-513). No code/substrate changes; modeling-discipline, CODING, and TESTING rubrics don't apply to brief edits. Internal cross-references stay consistent (carrier path src/v3/std/bin_shim.dag, instance dir dsl/std/runtime/bin_shims/), and STOP routing for carrier-shape pressure is preserved per design §5.4. Clean, narrowly scoped audit refresh.

Verified locally:

• HEAD: bea96e8c0 — matches review SHA.
• origin/main @ merge-base: 95f29b9d3 — matches metadata (95f29b9d).
• PR delta: git diff origin/main...HEAD --name-only is only
