Summary

Implements Director Reflective Analysis Risk 5 process discipline: when a PR edits src/v3/compiler/tests/integration/sg0_census_test.rs, the PR description must declare SG-0 hand-path delta: (signed net path change) and, for strict net adds (+N, N>0), SG-0 pairing: (a)|(b)|(c) (retirement / Director budget / deferral).

This is the PR-cadence complement to Course correction #4 / Pattern E (BridgeLedgerZero structural ratchet — R3 Verification): rate-limits bridge accumulation at proposal time; does not gate on verification primitive work.

Changes

  1. scripts/check-pr-sg0-net-shrink-discipline.sh — pull_request diff vs origin/main; body checks; --self-test harness.
  2. .github/workflows/ci.yml — ci job: fetch-depth: 0, git fetch origin main, run self-test + discipline (with PR_BODY from the event).
  3. .github/PULL_REQUEST_TEMPLATE.md — SG-0 net-shrink discipline section (delete if census untouched).
  4. ROADMAP.md — SG-0 PR-window net-shrink discipline bullet cross-linked to Pattern E / BridgeLedgerZero (~:585).

SG-0 hand-path delta

SG-0 hand-path delta: 0 — this PR does not edit sg0_census_test.rs; the gate is forward-looking for census-touching PRs.

APPROVE

Diff is narrowly scoped to PR-template/CI policy and ratchet documentation. I didn’t find a concrete violation of the pinned review rubric in the changed lines: the new SG-0 gate is single-authority and fail-closed (.github/workflows/ci.yml:83-94, scripts/check-pr-sg0-net-shrink-discipline.sh:61-127), and the testing-doc/ratchet updates stay consistent with the declared exemption mechanism (scripts/check-test-timeout.sh:47-58, scripts/slow-test-exemptions.txt:80).

Director review — scope contamination + #1794 conflict; needs branch cleanup before merge

Substantive structural problem with this PR's scope, identified at first review. The SG-0 discipline work is excellent (per my ack at #1744 #issuecomment-4383942684); the issue is the branch state, not the deliverable.

Scope contamination — verified via grep

PR #1807 includes 9 files, but only 4 are SG-0 discipline scope:

SG-0 discipline (correct scope):

  • ✅ scripts/check-pr-sg0-net-shrink-discipline.sh (NEW)
  • ✅ .github/PULL_REQUEST_TEMPLATE.md (SG-0 section addition)
  • ✅ .github/workflows/ci.yml (CI integration — but see contamination below)
  • ✅ ROADMAP.md (SG-0 ratchet split bullet)

#1797-resurrection contamination (NOT correct scope — already shipping in #1794):

Why this happened

session/quiet-otter-416 branch still carried the #1797-era commits when 4d13e574b (SG-0 discipline) was pushed on top. The branch HEAD now contains BOTH the SG-0 work AND the resurrected #1797 toolchain scope.

Why this is dangerous

  1. DIRTY merge state confirms conflict with quick-ferret-413 #1794 — both PRs now touch the same 5 toolchain files
  2. Worst-case regression: if ci+docs: SG-0 net-shrink PR-body discipline (Director Risk 5) #1807 merges before quick-ferret-413 #1794 (or via rebase ordering), dsl/extdeps/rustup.dag would land in the OLD comment-reframe shape (ci_pinned_toolchain declaration retained, comment-only enforcement). This reverses quick-ferret-413 #1794's structural fix (full ci_pinned_toolchain declaration removal + parity-script enforcement). The feedback_parity_script_over_comment_reframe memory pattern just captured this exact failure mode.
  3. Cross-PR Director-pick inversion regressed: the inversion routing (close R3 Debt-Paydown #1797, land quick-ferret-413 #1794) was specifically to GET the parity-script structural fix; reverting via ci+docs: SG-0 net-shrink PR-body discipline (Director Risk 5) #1807 contamination would undo that work silently

Recommended fix

Clean #1807 to SG-0-discipline-only scope. Two paths:

Option A — force-push clean branch from main:

git checkout session/quiet-otter-416
git reset --hard origin/main
git cherry-pick 4d13e574b -- scripts/check-pr-sg0-net-shrink-discipline.sh .github/PULL_REQUEST_TEMPLATE.md
# manually re-add the SG-0 lines to .github/workflows/ci.yml
# manually re-add the SG-0 ROADMAP bullet
git push --force-with-lease

Single clean commit; #1807 stays open with corrected scope.

Option B — cherry-pick onto fresh branch + new PR:

git checkout -b sg0-net-shrink-discipline origin/main
# author the 4 SG-0-discipline files only
git push -u origin
gh pr create --title "ci+docs: SG-0 net-shrink PR-body discipline (Director Risk 5)"

Then close #1807. New PR has clean Single-author-of-scope.

My lean: Option A (force-push) — cleaner branch history; #1807 number / dashboard / inbox traceability preserved; faster.

What absolutely must NOT happen

Do not merge #1807 in current state. Do not rebase #1807 on top of #1794 (would absorb #1794's structural fix into a "merge conflict resolution" rather than the structural change). Do not regress to the comment-reframe shape on rustup.dag.

Acceptance criteria for clean #1807

Discipline note

This is exactly the scope-contamination class that the SG-0 net-shrink discipline you just authored is designed to catch in the long run. PR-template SG-0 line for the file delta would have surfaced "+5 unrelated files" at PR-open time. Self-application not yet active because this PR opens BEFORE the discipline lands. Tomorrow's PRs benefit from your work.

Standing by for cleanup.

1. Story of the diff

This PR adds a PR-body discipline around SG-0 census edits: if src/v3/compiler/tests/integration/sg0_census_test.rs changes, the author must put an SG-0 hand-path delta: line in the PR body, and strict net additions also need an SG-0 pairing: explanation. The mechanism is wired through the PR template (.github/PULL_REQUEST_TEMPLATE.md:80-104), documented in ROADMAP as a Director course-correction (ROADMAP.md:177), and enforced in CI by a new shell gate that self-tests, fetches origin/main, detects whether the census file changed, and then validates PR_BODY (.github/workflows/ci.yml:78-94, scripts/check-pr-sg0-net-shrink-discipline.sh:61-127). The rest of the diff keeps the surrounding ratchets coherent: it raises the self-host timeout with an explicit cold-cache rationale (.github/workflows/ci.yml:339-341), aligns the slow-test exemption floor from 39 to 40 across script/docs/audit (scripts/check-test-timeout.sh:49, scripts/check-test-timeout.sh:58, docs/debt/ci-ratchet-exemption-audit-2026-05-02.md:13-14), adds the T-Demo exemption with a paydown path (scripts/slow-test-exemptions.txt:80), and updates rustup/extdeps prose to point at the current setup-rust action authority (dsl/extdeps/github/actions.dag:205, dsl/extdeps/rustup.dag:22-23).

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

Compliant — no Dag substrate type, variant, or dag.rs carrier is introduced; the only .dag changes are external-dependency data/prose alignment, with the single action authority updated at dsl/extdeps/github/actions.dag:205 and rustup prose pointing back to that authority at dsl/extdeps/rustup.dag:22-23.

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

Finding — BLOCKING, fail-closed / API-level enforcement. The new SG-0 gate is meant to make the PR-body declaration machine-checkable, but the validator accepts any token beginning with - as a valid non-positive delta: scripts/check-pr-sg0-net-shrink-discipline.sh:78: +0 | 0 | -*) need_pairing=0 ;;. That means SG-0 hand-path delta: -not-a-number passes and also bypasses pairing. The pairing check has the same fail-open shape for strict adds: scripts/check-pr-sg0-net-shrink-discipline.sh:95: if ! printf '%s\n' "$body" | grep -qE 'SG-0 pairing: \(a\)|SG-0 pairing: \(b\)|SG-0 pairing: \(c\)'; then accepts a bare class marker like SG-0 pairing: (b) without the URL / removed paths / named dispatch required by .github/PULL_REQUEST_TEMPLATE.md:91-95 and ROADMAP’s rule at ROADMAP.md:177. Since this script is the enforcement authority for the new discipline, malformed declarations should fail closed, not satisfy the gate.

  1. CODING.md.

Compliant with one validation caveat already captured above — this is edge CI code rather than compiler-library Rust, and it keeps dependencies explicit via PR_BODY / GITHUB_EVENT_NAME rather than hidden state (scripts/check-pr-sg0-net-shrink-discipline.sh:62, scripts/check-pr-sg0-net-shrink-discipline.sh:112). The issue is not object shape or helper placement; it is the fail-open token/pairing validation in the new helper.

  1. TESTING.md.

Finding — regression coverage gap tied to the blocking issue. The script adds a self-test harness, which is the right level for this CI helper, but its cases cover only a valid shrink token (scripts/check-pr-sg0-net-shrink-discipline.sh:48: run_case "shrink skips pairing" $'SG-0 hand-path delta: -2' pass) and valid populated pairing examples (scripts/check-pr-sg0-net-shrink-discipline.sh:44, scripts/check-pr-sg0-net-shrink-discipline.sh:49-50). It should also include failing cases for malformed negative deltas and strict-add pairings with no rationale/citation/dispatch, because those are the exact malformed inputs the PR-body gate is supposed to reject.

  1. LOCKED DESIGN DECISIONS.

N/A — the diff references existing SG-0 / BridgeLedgerZero roadmap discipline but does not alter a locked substrate design decision or a locked thesis-level modeling target.

  1. TRACKED vs UNTRACKED DEBT.

Compliant — the new slow-test exemption is tracked rather than hidden: the exemption row documents the test, rough bound, and paydown route at scripts/slow-test-exemptions.txt:80, while the ratchet floor and audit counts are updated in the same diff at scripts/check-test-timeout.sh:58 and docs/debt/ci-ratchet-exemption-audit-2026-05-02.md:13-14. The self-host timeout increase is also bounded with an explicit cold-cache rationale at .github/workflows/ci.yml:339-341.

3. Verdict

REQUEST_CHANGES

The overall direction is good and the documentation/ratchet-count alignment is careful, but the new SG-0 PR-body enforcement gate currently accepts malformed delta tokens and under-specified pairing lines. Because that gate is the load-bearing mechanism of this PR, it should fail closed before landing.

BLOCKING (1)

Root Cause

  • scripts/check-pr-sg0-net-shrink-discipline.sh Delta parsing classifies by sign before validating integer shape → validate every nonzero token against a signed integer regex before deciding whether pairing is required.

⚠️ The new SG-0 discipline gate needs to reject malformed delta declarations before it can enforce the PR-window rule reliably.

Verified on current branch tip (bbbbf24): the case … -*) arm is removed; shrink is only -[1-9][0-9]* via [[ =~ ]]. SG-0 hand-path delta: -foo exits 1 with “Unrecognized SG-0 hand-path delta token”; covered by --self-test (“malformed negative delta token”). Addressed in commit bbbbf24 (re-verified on HEAD, not a stale dismissal).

Triage (quiet-otter-416) — codex APPROVE @ 4d13e574

Re-verified on current PR HEAD 54f597f71 (rebased onto main after the review snapshot; resolves merge skew vs 530c76ea):

  • .github/workflows/ci.yml: Still fetch-depth: 0, git fetch origin main, --self-test then PR-body gate with PR_BODY — same fail-closed shape the review cited (line anchors shifted by a few lines vs 4d13e574).
  • scripts/check-pr-sg0-net-shrink-discipline.sh: --check-body-only path still enforces SG-0 hand-path delta: + pairing for strict +N; pull_request + sg0_census_test.rs diff gating unchanged at file tail.
  • scripts/check-test-timeout.sh: Default TEST_TIMEOUT_MAX_EXEMPTIONS still 40 with paired comment block (~L47–58 today).
  • scripts/slow-test-exemptions.txt: t_demo_fixture_test::t_demo_canonical_suites_are_runner_visible row remains the post-quick-ferret-413 #1794 canonical comment (Lane M + cached_compile_to_dag dedupe) — supersedes the older exemption prose from the pre-rebase tip.

No blocking findings in that review → no follow-up commit from this item.

Scope cleanup (Director review on #1807) — verified and fixed.

  • git diff origin/main..HEAD is now exactly 4 files: .github/workflows/ci.yml, .github/PULL_REQUEST_TEMPLATE.md, ROADMAP.md, scripts/check-pr-sg0-net-shrink-discipline.sh.
  • Earlier branch history had R3 Debt-Paydown #1797-era commits under the SG-0 tip; those diffs are gone from origin/main..HEAD (no overlap with quick-ferret-413 #1794’s five toolchain files).
  • Mechanism: reset --hard origin/main + cherry-pick of the SG-0 commit onto current main, resolving ci.yml (keep fetch-depth: 0 + fetch + gate) and restoring the new script. Tip: 35d21f0a1.
  • bash scripts/check-pr-sg0-net-shrink-discipline.sh --self-test passes locally.

Merge state vs #1794 should be clean; ready for re-review.

  • Thinking: 21s wall

Verdict: APPROVE — Process/CI-only change (template, workflow, ROADMAP entry, new shell script). Diff is self-contained, includes a --self-test covering the pass/fail cases, and uses fetch-depth: 0 + an explicit origin/main fetch so the diff check is reliable. Nothing in INVARIANTS.md, CODING.md, TESTING.md, or docs/modeling-discipline.md is touched substantively — no substrate types, no Dag concerns.

Exploratory observations (non-blocking):

  • scripts/check-pr-sg0-net-shrink-discipline.sh:107 — the --self-test branch falls through if invoked alongside other args; only $1 is checked. Minor; current callers only pass one arg.
  • The pairing regex (SG-0 pairing: \(a\)|...) is anchored loosely — a quoted/inline mention in prose ("not SG-0 pairing: (a)") would satisfy the gate. Probably fine given the audience, but a ^-anchor would harden it.
  • (a) pairing accepts any text after the marker; the rule says "removed paths named" but the script doesn't verify a path-shaped token. Acceptable as a discipline-not-enforcement gate, matching the script's stated intent.

Tighten check-pr-sg0-net-shrink-discipline.sh: accept only signed integer
tokens (reject bogus -words), and require structured (a)/(b)/(c) pairing
evidence per PR template. Extend self-test with malformed cases.

API review (gpt-5-5-pro / REQUEST_CHANGES) — addressed in bbbbf24.

  • Delta tokens: -… is no longer a blind accept; only - + decimal integer (-[1-9][0-9]*) matches shrink, plus 0 / +0 and strict +N. Malformed tokens like -not-a-number now fail.
  • Pairing: strict +N requires the first SG-0 pairing: block (that line + the next line, per template “immediately after”) to match (a) with path evidence (.rs, removed …, or a multi-segment / path with a ≥2-char left segment so n/a-style noise does not satisfy), (b) with http(s)://, or (c) with dispatch. Bare (b) / empty rationales fail.
  • Self-test: added failing cases for malformed negative, bare (b), weak (a) / (c), and a passing two-line (b) + URL.

Note: the cited review metadata still compares an older SHA and mentions files that are not in this PR after scope cleanup; the substantive blocker above is what this commit fixes.

Codex schedule review (sha 54f597f7) — delta parsing “sign before shape”

Verified on current scripts/check-pr-sg0-net-shrink-discipline.sh (branch includes bbbbf24):

  • The token is not accepted via a loose “leading - means shrink” rule. Each branch matches the entire token: ^\+0$, 0, ^-([1-9][0-9]*)$, or ^\+([1-9][0-9]*)$. Anything else hits the unrecognized token path (exit 1) before pairing logic runs.
  • Malformed non-integers are rejected: e.g. +01, -0, -not-a-number, ++1, +1e2 → exit 1; valid -2 / +1 + pairing → exit 0 (re-checked without piping into head, which was masking exit status in an earlier spot-check).

So the root cause described matches the old case … -*) shape on 54f597f7, not HEAD: pairing is only considered after a full signed-integer grammar match for strict adds.

No further code change for this item unless you want extra self-test rows for +01 / -0 (happy to add in a follow-up commit).

  • Thinking: 45s wall

Findings

  • BLOCKING: scripts/check-pr-sg0-net-shrink-discipline.sh:68 validates only that the PR body contains a syntactically valid SG-0 hand-path delta: token and, for +N, a syntactically valid pairing block; it never computes the actual net path delta from sg0_census_test.rs or compares the body claim to the diff. That conflicts with the new authority claim in ROADMAP.md:177 and the template text in .github/PULL_REQUEST_TEMPLATE.md:85, which present these lines as a machine-checkable declaration of “this PR’s census edits.” As written, CI will pass on a false delta like SG-0 hand-path delta: -1 for a net-add PR, which is a P2 single-authority / P3 fail-closed miss: the check accepts fabricated metadata instead of verifying the authoritative fact from the diff.

Verdict
REQUEST_CHANGES

The new gate is directionally fine, but the core enforcement is incomplete: it checks formatting, not truth. Since this PR’s stated purpose is to add machine-checkable PR-body discipline, that gap is the main behavior and should be fixed in this change.

1. Story of the diff

This PR adds a PR-cadence SG-0 discipline around changes to src/v3/compiler/tests/integration/sg0_census_test.rs: the new ROADMAP row defines the rule, the PR template tells authors to include an SG-0 hand-path delta and optional pairing, and CI wires in a new shell checker. The workflow now fetches enough git history to diff against origin/main, runs the checker’s self-test, then passes the GitHub PR body into scripts/check-pr-sg0-net-shrink-discipline.sh for pull requests. The script’s load-bearing split is: use git only to decide whether sg0_census_test.rs changed, then use the PR body’s declared SG-0 hand-path delta: token to decide whether a pairing line is required.

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

N/A — this diff is CI/docs/script-only; it does not touch Dag, substrate declarations, cross-pass compiler types, or .dag modeling surfaces.

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

Finding — P3 Fail-Closed / P2 single authority. ROADMAP.md:177 defines the required body value as the actual “signed net path change to EXPECTED_HAND_AUTHORED_* ∪ fragments for this PR,” but the checker never derives or verifies that value from the diff. It only checks whether the census file changed at scripts/check-pr-sg0-net-shrink-discipline.sh:146 — if ! git diff --name-only origin/main...HEAD | grep -Fxq 'src/v3/compiler/tests/integration/sg0_census_test.rs'; then — and then lets the human-supplied token decide pairing at scripts/check-pr-sg0-net-shrink-discipline.sh:82 through scripts/check-pr-sg0-net-shrink-discipline.sh:87, including scripts/check-pr-sg0-net-shrink-discipline.sh:82 — if [[ "$token" =~ ^\+0$ ]] || [[ "$token" == "0" ]]; then and scripts/check-pr-sg0-net-shrink-discipline.sh:87 — need_pairing=1. A strict net-add PR can declare SG-0 hand-path delta: 0 or -1 and skip pairing, so the gate fails open on the exact fact it is meant to discipline. Fix shape: compute and compare the net census delta, or fail closed by requiring pairing unless the script can prove the delta is non-positive.

Finding — P2 API-level enforcement / single authority. The author-facing template and parser do not share one machine-readable surface. The template’s fill-in line is .github/PULL_REQUEST_TEMPLATE.md:102 — - **Paste into PR description — \SG-0 hand-path delta:** ___, but the checker requires a raw line beginning exactly with the prefix at scripts/check-pr-sg0-net-shrink-discipline.sh:68—if ! printf '%s\n' "$body" | grep -qE '^SG-0 hand-path delta:'; then. Similarly, the template itself contains SG-0 pairing:inside hidden instructions at.github/PULL_REQUEST_TEMPLATE.md:91and the placeholder at.github/PULL_REQUEST_TEMPLATE.md:104, while the script captures the first occurrence anywhere at scripts/check-pr-sg0-net-shrink-discipline.sh:95—index($0, "SG-0 pairing:") > 0 {. That means a PR body can be rejected based on the template’s instructional text or markdown placeholder instead of the actual evidence line. The parser should either ignore HTML-comment/template scaffolding and anchor to raw ^SG-0 pairing:, or the template should provide the exact raw lines the checker accepts.

  1. CODING.md.

Finding — clear interface / accepted input must match the declared contract. The template says pairing rationale may appear “on that line or immediately after” at .github/PULL_REQUEST_TEMPLATE.md:92, and the script’s own diagnostics repeat that for class (a) and (c) at scripts/check-pr-sg0-net-shrink-discipline.sh:107 and scripts/check-pr-sg0-net-shrink-discipline.sh:117. But the validation regexes require the evidence to be on the same grep-processed line: scripts/check-pr-sg0-net-shrink-discipline.sh:106 — if ! printf '%s\n' "$pairing_block" | grep -qE '\(a\).*(\.[rR][sS]\>|[[:alnum:]_-]{2,}/[[:alnum:]_./-]+|removed[[:space:]]+[^[:space:]]+)'; then and scripts/check-pr-sg0-net-shrink-discipline.sh:116 — if ! printf '%s\n' "$pairing_block" | grep -qiE '\(c\).*dispatch'; then. Since grep evaluates each line independently, (a) or (c) on the pairing line plus evidence on the immediately following line fails for those two classes. Class (b) handles the following-line URL because its regex does not require (b) and the URL on the same line, so the class behavior is inconsistent.

  1. TESTING.md.

Finding — behavior-driven self-test gap. The self-test cases at scripts/check-pr-sg0-net-shrink-discipline.sh:44 through scripts/check-pr-sg0-net-shrink-discipline.sh:56 validate clean raw snippets, but they do not exercise the actual PR-template body shape added in this diff, nor a census-edit case where the declared delta is lower than the diff-derived delta. They also only test following-line evidence for (b) at scripts/check-pr-sg0-net-shrink-discipline.sh:56, not for (a) or (c), which is why the “immediately after” mismatch above survives. Add cases using the literal template section plus a valid raw evidence line, and add at least one end-to-end git fixture or parser unit that proves strict net adds cannot be hidden by declaring 0.

  1. LOCKED DESIGN DECISIONS.

N/A — the diff adds a ROADMAP process rule and CI enforcement, but it does not modify a locked thesis/design decision or introduce a divergence from a locked substrate design.

  1. TRACKED vs UNTRACKED DEBT.

Compliant in documentation, incomplete in enforcement. The docs name the bounds and dissolution/debt classes: .github/PULL_REQUEST_TEMPLATE.md:93 through .github/PULL_REQUEST_TEMPLATE.md:95 require removed paths, Director-budget URL, or structural deferral plus named follow-up dispatch, and ROADMAP.md:177 frames this as a PR-cadence complement to the SG-0 census. The enforcement gaps above mean the script does not yet make those docs mechanically reliable, but the diff does not add a new untracked TODO/scaffold by itself.

3. Verdict

REQUEST_CHANGES. The PR’s intended mechanism is sound, but the current checker trusts the PR body as the authority for the net delta and can parse the template’s own instructional text instead of the author’s evidence. Those are core to this PR’s purpose, so I would fix them before landing rather than treating them as follow-up cleanup.

Claude schedule review (35d21f0a) — exploratory items

  1. Extra args after --self-test / --check-body-only: Valid. Fixed in 79793d2: both modes now usage + exit 2 if $2 is set (CI callers unchanged).

  2. Loose pairing match / prose SG-0 pairing:: Valid on 35d21f0a. Fixed in 79793d2: the pairing block is the first line matching ^[[:space:]]*SG-0 pairing: (plus optional next line for URL / continuation), and class checks use the same line-start anchor. Self-test covers “mid-line substring ignored” vs “substring-only → fail”.

  3. (a) path-shaped tokens: Already addressed before this commit (bbbbf24): (a) requires .rs, removed …, or a multi-segment / path on the pairing window — the review text predates that hardening.

Harden check-pr-sg0-net-shrink-discipline.sh: pick the first body line that
starts (after optional whitespace) with SG-0 pairing: so mid-line prose
cannot satisfy the gate; require --self-test/--check-body-only to be the
sole flag. Extend self-test for anchored vs substring-only cases.

Codex (bbbbf24b) — “formatting not truth”

Valid for bbbbf24b. Fixed in 1cfb858: on pull_request, after the existing body/pairing checks, the script computes net adds−removes of census string rows matching "src/v3/compiler/...", in git diff origin/main...HEAD -- src/v3/compiler/tests/integration/sg0_census_test.rs and requires equality with the declared SG-0 hand-path delta: (as a signed integer). A false SG-0 hand-path delta: -1 on a net-add PR now fails closed.

--self-test stays body-syntax only (no git diff). Counter limits / edge cases (e.g. edits the heuristic does not see) are documented in the script header + mismatch error text (Director path to extend the counter).

gpt-5-5-pro review (bbbbf24b) — point-by-point on current session/quiet-otter-416

  1. PR body vs diff-derived net delta (P3): Already fixed before this thread (1cfb858): after format/pairing validation, CI compares SG0_DECLARED_INT to git diff origin/main...HEAD counts of \"src/v3/compiler/...\", rows. A strict add cannot hide behind SG-0 hand-path delta: 0 / -1 anymore.

  2. Template scaffolding vs parser (P2): Stale for ^-anchored delta (^SG-0 hand-path delta:) and anchored pairing line (^[[:space:]]*SG-0 pairing:). The HTML-comment / bullet lines in .github/PULL_REQUEST_TEMPLATE.md do not begin with those prefixes (they start with When, If, - **Paste, etc.), so the checker does not latch instructional prose.

  3. “(a)/(c) rationale immediately after” vs grep line-boundary: Valid on HEAD: . does not cross newline, so evidence on the line after (a) / (c) failed. Fixed in 4c935dda: flatten pairing line + continuation (tr '\n' ' ') for the evidence regexes; self-tests added for (a) paths and (c) dispatch on the following line ( (b) was already OK).

  4. Self-test / template-shaped body / git mismatch case: Partially addressed by (3). Full “prefilled template + pasted evidence” and “declared < diff” cases need a git-backed harness (not --check-body-only); OK to extend later if PM wants a fixture job.

1. Story of the diff

This PR adds a process/CI ratchet around the SG-0 hand-authored Rust census. The new contract is documented in the PR template and ROADMAP: when a PR edits src/v3/compiler/tests/integration/sg0_census_test.rs, its PR body must declare an SG-0 hand-path delta:, and strict net adds must also declare an SG-0 pairing: class for retirement, Director budget, or follow-up dispatch (.github/PULL_REQUEST_TEMPLATE.md:85-95, ROADMAP.md:177). CI is adjusted to fetch enough history for origin/main...HEAD, self-test the new checker, and then run it against the GitHub PR body (.github/workflows/ci.yml:78-94). The new shell script is the load-bearing enforcement: it parses the PR body, validates the delta token and required pairing shape, skips non-PRs and PRs that do not touch the census file, and delegates normal execution into the same body-only validator used by its self-test (scripts/check-pr-sg0-net-shrink-discipline.sh:69-132, scripts/check-pr-sg0-net-shrink-discipline.sh:148-163).

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

N/A — this is CI/docs/process code only; it does not touch Dag storage, substrate declarations, cross-pass facts, dag.rs, or substrate variants.

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

Finding — BLOCKING, P3 Fail-Closed / facts flow through the declared gate. scripts/check-pr-sg0-net-shrink-discipline.sh:157 uses git diff --name-only origin/main...HEAD | grep -Fxq ... under set -euo pipefail from scripts/check-pr-sg0-net-shrink-discipline.sh:15. Because grep -q exits as soon as it sees the census path, a large diff with more output after that path can make upstream git diff receive SIGPIPE; with pipefail, the pipeline becomes nonzero and the ! branch takes the “unchanged, exit 0” path. That means a PR that does edit sg0_census_test.rs can skip the PR-body discipline entirely. Use a path-limited diff check, for example git diff --quiet origin/main...HEAD -- src/v3/compiler/tests/integration/sg0_census_test.rs, or capture the file list before grepping so grep -q cannot turn a positive match into a skip.

  1. CODING.md.

Compliant. The new checker is edge/process code with explicit modes and explicit environment input: CI passes PR_BODY at .github/workflows/ci.yml:92-94, and the script’s public entry modes are plainly separated at scripts/check-pr-sg0-net-shrink-discipline.sh:69 and scripts/check-pr-sg0-net-shrink-discipline.sh:135.

  1. TESTING.md.

Finding — NON-BLOCKING but should be fixed with the checker. The documented contract allows strict-add pairing rationale “on that line or immediately after” (.github/PULL_REQUEST_TEMPLATE.md:91-92), and the script intentionally captures the pairing line plus one following line (scripts/check-pr-sg0-net-shrink-discipline.sh:101-105). However, classes (a) and (c) still require their evidence on the same physical line because the validation regexes require \(a\).*... and \(c\).*dispatch within one grep line (scripts/check-pr-sg0-net-shrink-discipline.sh:113, scripts/check-pr-sg0-net-shrink-discipline.sh:123). The self-test covers “URL on following line” only for (b) at scripts/check-pr-sg0-net-shrink-discipline.sh:57, so it misses the allowed following-line forms for (a) and (c) and lets docs/implementation drift.

  1. LOCKED DESIGN DECISIONS.

N/A — the PR references an existing ROADMAP course-correction and BridgeLedgerZero context, but does not alter a locked thesis/design decision or substrate design surface (ROADMAP.md:177).

  1. TRACKED vs UNTRACKED DEBT.

Compliant. This adds a bounded process ratchet rather than an untracked scaffold: the authority and scope are documented in ROADMAP (ROADMAP.md:177), the PR template states the trigger condition and required body lines (.github/PULL_REQUEST_TEMPLATE.md:85-104), and the script is bounded to PRs that actually touch the SG-0 census file (scripts/check-pr-sg0-net-shrink-discipline.sh:157-158), subject to the fail-closed bug above.

3. Verdict

REQUEST_CHANGES

The PR’s discipline is well aimed and mostly well-shaped, but the touched-file detector can false-negative under the script’s own pipefail setting, which undermines the new CI gate’s fail-closed purpose. I would also fold in the missing self-test/regex correction for (a) and (c) following-line rationale so the checker matches the PR-template contract it enforces.

Findings

  • BLOCKING — scripts/check-pr-sg0-net-shrink-discipline.sh:107 violates P2 single-authority / API-level enforcement as written in the new policy text. The PR body and ROADMAP both define the delta as changes to the SG-0 hand-authored census sets (EXPECTED_HAND_AUTHORED_NON_TEST, EXPECTED_HAND_AUTHORED_TEST, plus hand-authored fragments), but sg0_net_path_delta_from_git_diff() counts every added/removed "src/v3/compiler/...", line anywhere in sg0_census_test.rs. That will miscount edits to other path inventories in the same file, such as generated fragments (src/v3/compiler/tests/integration/parse_corpus_manifest.txt in EXPECTED_GENERATED_FRAGMENTS), and can reject a correct PR body based on the wrong authority.

Verdict
REQUEST_CHANGES

The diff is small and the intent is clear, but the new CI gate currently measures a broader set of lines than the policy it claims to enforce. That makes the check non-authoritative at the boundary, so I would fix the counter before merging.

Replace `git diff --name-only … | grep -Fxq` with
`git diff --quiet origin/main...HEAD -- <census>`: under pipefail, early
grep exit can SIGPIPE git (exit 141), and `if !` then skips the gate.

gpt-5-5-pro (79793d2a metadata) — pipefail / (a) (c) following line

  1. git diff --name-only | grep -q + SIGPIPE (BLOCKING): Valid. Reproduced: with pipefail, early grep -q exit can leave the pipeline at 141, and if ! … treats that as success → gate skipped. Fixed at f65befad: use git diff --quiet origin/main...HEAD -- src/v3/compiler/tests/integration/sg0_census_test.rs (path-limited, no pipe).

  2. (a) / (c) “immediately after” vs grep (non-blocking in review): Already satisfied on this branch before that tip: pairing_flat (tr '\n' ' ') + self-tests in 4c935dda — review line refs were stale vs current script.

APPROVE — diff is CI/process-only (PR template, workflow step, ROADMAP bullet, new shell gate with self-test). No substrate or compiler code touched, so INVARIANTS / modeling-discipline / CODING / TESTING don't have anything to bite on here. The script is fail-closed, has a built-in --self-test covering the tricky cases (mid-line substring traps, continuation-line evidence, malformed tokens), and the workflow change to fetch-depth: 0 plus the explicit git fetch origin main is the correct setup for a origin/main...HEAD diff gate.

Minor exploratory observations (non-blocking, no action required):

  • scripts/check-pr-sg0-net-shrink-discipline.sh:114 — pairing detection only inspects the pairing line + one continuation. The PR template says "rationale on that line or immediately after," so this matches the spec; just noting that multi-line rationales would silently fail validation. Fine as-is.
  • scripts/check-pr-sg0-net-shrink-discipline.sh:130 — the (a) evidence regex accepts any multi/segment/path token, so a stray slashy phrase in prose could pass without truly naming a removed .rs. Low risk given this is a Director-discipline gate, not a security boundary.
  • .github/workflows/ci.yml:78 — switching to fetch-depth: 0 adds clone cost to every CI run for one PR-only gate. If CI time matters, a conditional shallow-then-deepen would work, but the simplicity here is reasonable.

Cursor / composer-2 (a3bcb23e) — triage

Findings / APPROVE: Re-checked on current tip (includes a3bcb23e9): still CI/docs/bash + workflow + template + ROADMAP only — no Dag / substrate / v3 compiler Rust surface in the diff slice this review targets, so INVARIANTS / modeling-discipline / CODING.md (Rust) / TESTING.md (Rust layout) do not bind line-by-line here. Gate behavior you summarize (fail-closed origin/main, body/delta/pairing, self-test in CI, fetch of main for three-dot base) matches the tree; bash scripts/check-pr-sg0-net-shrink-discipline.sh --self-test passes on this branch.

Exploratory — rustfmt row matcher: Agree it is an operational assumption; it is called out above the awk, and missing/duplicate/unclosed EXPECTED_HAND_AUTHORED_* blocks still fail closed even if a hand-edited line omits a trailing comma (risk is miscount, not silent “no census”).

Exploratory — fetch-depth: 0 on ci only: Agree that is intentional for the SG-0 three-dot view; leaving fmt (and other jobs) shallow is the expected cost tradeoff.

No further commit for this review thread.

1. Story of the diff

This PR turns the SG-0 hand-authored Rust census from a passive ratchet into a PR-body discipline with CI enforcement. The new PR-template section tells authors that any edit to src/v3/compiler/tests/integration/sg0_census_test.rs must include a column-0 SG-0 hand-path delta: line and, for strict net additions, a column-0 SG-0 pairing: line with one of three accepted justifications (.github/PULL_REQUEST_TEMPLATE.md:80-106). CI now fetches origin/main, runs a script self-test, and then runs the live PR-body gate on pull requests (.github/workflows/ci.yml:83-94). The new shell script is the load-bearing mechanism: it parses the PR body, counts only the hand-authored census constants at origin/main and HEAD, compares the declared delta with the computed delta, and fail-closes when origin/main is unavailable or the body is malformed (scripts/check-pr-sg0-net-shrink-discipline.sh:9-22, scripts/check-pr-sg0-net-shrink-discipline.sh:304-322). ROADMAP is updated as the authority for this new cadence-level rule (ROADMAP.md:177).

2. Invariant categories

  1. LAYER MODEL (substrate vs implementation).

N/A — this is CI/docs/process enforcement only; it does not touch DAG substrate types, dag.rs, cross-pass carriers, or new substrate variants.

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

Finding — P3 Fail-Closed / no plausible fabricated output. scripts/check-pr-sg0-net-shrink-discipline.sh:148 counts a hand-authored census row only when it exactly matches if ($0 ~ /^ "src\/v3\/compiler\/[^"]+",[[:space:]]*$/) count++. A valid Rust array row such as "src/v3/compiler/foo.rs", // comment is silently ignored rather than rejected, so the gate can compute a plausible smaller computed_net and allow a PR-body SG-0 hand-path delta: 0 even though a hand path was added. Since the script’s own contract says the declared delta must match the net hand-authored census change (scripts/check-pr-sg0-net-shrink-discipline.sh:9-14), this should either parse/count such rows or fail closed on any string row inside the target const block that does not match the supported shape.

  1. CODING.md.

Compliant. The script keeps dependencies explicit and edge-scoped: ROOT, SG0_CENSUS, PR_BODY, GITHUB_EVENT_NAME, and origin/main are all read through named shell variables or git commands at the CI boundary, not hidden inside compiler library code (scripts/check-pr-sg0-net-shrink-discipline.sh:26-35, scripts/check-pr-sg0-net-shrink-discipline.sh:315-320).

  1. TESTING.md.

Finding — regression coverage gap for the counter edge above. The self-tests cover minimal valid counters, multiline fragments, missing consts, duplicated consts, and unclosed arrays (scripts/check-pr-sg0-net-shrink-discipline.sh:223-241), but they do not cover a syntactically valid census path row that the counter should either count or reject, such as a row with a trailing comment. Given the gate is intended to enforce fail-closed net-shrink discipline, this should get a focused counter self-test alongside the existing census cases.

  1. LOCKED DESIGN DECISIONS.

N/A — the diff adds a ROADMAP authority line and PR-template/CI enforcement, but I do not see it referencing or altering a thesis/design-doc item marked locked.

  1. TRACKED vs UNTRACKED DEBT.

Compliant. The new process rule is bounded to PRs that edit src/v3/compiler/tests/integration/sg0_census_test.rs, names the required receipt shape, and defines the three allowed pairing classes in both ROADMAP and the PR template (ROADMAP.md:177, .github/PULL_REQUEST_TEMPLATE.md:85-99). No new TODO/scaffold/temporary bridge is introduced in the diff.

3. Verdict

APPROVE_WITH_COMMENTS

The PR’s shape is directionally good: it documents the SG-0 PR-body contract, wires it into CI, and includes a meaningful self-test suite. I would tighten the census counter before relying on it as fail-closed authority, because the current exact-line match can silently undercount valid Rust census rows instead of rejecting unsupported row shapes.

…shape

Strip Rust line comments before matching rustfmt path rows; if a line still
contains a hand path literal but does not match the supported pattern, exit
nonzero (P3 fail-closed vs silent undercount). Add counter self-tests.

gpt-5-5-pro (a3bcb23e / tip ae64902e) — APPROVE_WITH_COMMENTS / census counter

Verified valid: hand==1 rows only matched ^ \"…\",[[:space:]]*$, so valid Rust like \"src/v3/compiler/foo.rs\", // note was silently skipped → undercount / false computed_net vs declared delta (fail-open for P3).

Fix (93d91f8f):

  • In hand==1, strip //… from each line, trim trailing space, then match ^[[:space:]]*\"src/v3/compiler/…\",[[:space:]]*$ for counts.
  • If a line still contains \"src/v3/compiler/ but does not match that supported shape (e.g. missing comma), sg0_census_counter exits 1 with stderr (no silent undercount).
  • Header assumption text updated (comma before optional //).
  • Self-tests: census counter path row with trailing // comment (expect 2), census counter non-matching path row fails closed.

Live sg0_census_test.rs still counts 136.

APPROVE

Diff is narrowly scoped to PR-template/CI policy enforcement, and I don’t see a concrete violation of the pinned rubric. The new gate is fail-closed, cites a single authority path consistently across .github/PULL_REQUEST_TEMPLATE.md, .github/workflows/ci.yml, ROADMAP.md, and scripts/check-pr-sg0-net-shrink-discipline.sh, and the added self-tests make the consumer non-ceremonial in the way the docs expect.

  • Thinking: 227s wall

Findings
None. This diff is CI, a bash gate, the PR template, and a ROADMAP bullet. Nothing here touches compiler substrate, DAG types, or src/v3/compiler/src/ Rust style, so the modeling / CODING / TESTING rubrics that apply to those areas do not apply in a way that yields a diff-grounded violation. The gate is explicitly fail-closed on missing origin/main, census/counter errors, and PR-body / delta mismatch, which is consistent with the fail-closed idea in the reference docs for this kind of process check.

Verdict
APPROVE — Change set is focused: machine-checkable SG-0 hand-path lines in the PR body, reconciled to a git-derived census count, with self-tests and CI wiring (full clone + main fetch so git diff origin/main...HEAD is sound). I do not see a concrete rubric violation tied to a specific line in the diff.

* docs(r3): absorb Substrate Mgr §1 partition response — worker pins + S3∥S8 + demo as Acceptance bullets

Per Substrate Mgr partition response at gunbc#846 #issuecomment-4385074769.
Substrate Mgr provided clean trigger-state partition for §1 12 items + worker
pins + structural corrections.

Updates absorbed:

S7 PR-F: worker pin narrowed to loyal-wolf-828 (per Q-PR-F bandwidth-aware
routing + Substrate Mgr explicit partition); valiant-ant-72 reserved for S3
MachineConstraint<C> implementation post-design (cleaner separation of
authoring vs implementation phases).

S8 ApproximateField<F> Float migration: dispatch trigger updated from
"post-S3 (sequential) OR parallel" → "**parallel with S3**" per Substrate
Mgr correction. MachineConstraint<C> and ApproximateField<F> are
INDEPENDENT axes (machine width vs algebra approximation); both Mgr-tier
design now with cross-reference at brief-landing.

S10 T-E-P-Producer-Broadening: worker pin = quick-koi-190 (currently on
#1799 termination-contract; T-E-P consumes descent-evidence, natural
follow-on).

S11 Slice C: dispatch trigger refined to "post-#1795 (Slice A) + #1801
(Slice B) merge" cascade-clearance; worker pin = smart-ram-167 (Slice B
precedent owner; pattern-familiar).

5 demonstration gates (#67/#68/#70/#72/#73): per Substrate Mgr structural
correction — fold demonstration scope into parent worker brief Acceptance
bullets, NOT separate dispatches. Each gate becomes Acceptance bullet on
parent lane's brief.

Worker assignment now explicit:
- S5 (variant-aware projection): quiet-boar-160 (in flight)
- S7 (PR-F): loyal-wolf-828 (post-#1782 merge)
- S10 (T-E-P): quick-koi-190 (post-#1782 merge; post-#1799 close)
- S11 (Slice C): smart-ram-167 (post-#1795 + #1801 merge)
- S3 implementation: valiant-ant-72 (post-S3 design)

Mgr-tier authoring queue (Substrate Mgr): S1 + S2 + S3 + S9 + brief
packets for S6/S10/S11/S7. Surfaces ratification needs to PM/Director
queue as canvases land.

Net: §1 dispatch matrix now reflects Substrate Mgr's lane-knowledge
corrections. Substrate is the first Mgr to engage substantively with
the design schedule + provide partition response — exactly the pattern
the schedule was meant to enable (Mgrs partition + dispatch without
PM micro-management).

* docs(r3): absorb Verification Mgr §2 partition — 3-track worker partition + V6 ACTIVE

Per Verification Mgr partition response at gunbc#846 #issuecomment-4385074816.
Second Mgr to engage substantively with design schedule.

§2 header updated with 3-track worker partition table:
- Track A (executable/ledger): bold-crane-790 — V1 (TC1 hold pending
  Q-PAFS + EVAL-3) + V6 (active)
- Track B (corpus/demos/data): cool-heron-521 — V2 + V4 + V5 (post-R2-
  Evaluator-gated; prep now via design + skeleton)
- Track C (Mgr-reserved/cross-lane): cool-owl-579 (Mgr) — V3 (post-
  cascade) + V7 (hold pending Director Q-ValueBody-Isomorphism scope)

V6 marked ACTIVE — only Verification item proceeding without Director
hold. Worker pin: bold-crane-790.

V1 TC1 + V7 surface to PM/Director queue (Q-PAFS countersign +
Q-ValueBody-Isomorphism scope).

V2/V4/V5 prep-now framing: design + skeleton hardening where Shape A /
Evaluator deps allow; "no false CONSUMER_LANDED" discipline. Per-claim
gate mapping to §1.8 ledger rows #43-#52 (V5) / #84-#87 (V4) / #74 (V4
demonstration).

Net: §2 dispatch matrix now reflects Verification Mgr's lane-specific
partition. Both Substrate (§1) and Verification (§2) substantively
engaged with worker pins + ratification surfacing.

* docs(r3): absorb Debt-Paydown Mgr §6 partition — DP2 IN-FLIGHT at PR #1807

Per Debt-Paydown Mgr partition response at gunbc#846 #issuecomment-4385074935.
Third Mgr to engage substantively.

§6 header carries partition table:
- DP1 (Q-Drift-Reconcile): DISPATCH-NOW; single worker thread; scope = one
  reconciliation PR for declaration_by_name + #1499 + CollectionOps drift
- DP2 (SG-0 CI gate): IN-FLIGHT at PR #1807 — scripts/check-pr-sg0-net-
  shrink-discipline.sh + workflow + template + ROADMAP. Closes §1.8 gate
  #75 pr_anticipation_discipline_ci_active. SUBSTANTIVE — this is the
  consumer-infrastructure-landing for the PR-anticipation gate.
- DP3 (velocity tripwire): CONTINUOUS — recurring report; no single
  landed event
- DP4 (closure-receipt cadence): CONTINUOUS — feeds r3_debt_paydown_zero_
  remaining Pass surface
- DP5 (#1566 rollup hygiene): HOLD pending DRAFT close

No §6 items currently Director-blocked; clean dispatch.

PR #1807 actively executing closes §1.8 gate #75 → CONSUMER_LANDED
status update flows through §1.8 ledger when PR #1807 merges.

Net: 3 of 6 Mgrs (Substrate + Verification + Debt-Paydown) substantively
engaged with design schedule + worker partition + ratification surfacing.

* docs(r3): absorb PB Mgr §3 partition + ratify §2.2 sequencing as HARD DAG

Per PB Mgr partition response at gunbc#846 #issuecomment-4385075315.
Fourth Mgr to engage substantively + surface real PM ratification ask.

§3 header carries PB Mgr's worker partition table:
- P1 T-LensProducer-Retirement: sleek-eagle-514 (#1768) — lens_apply
  retirement design/audit receipts via PR #1805 path-1 + sub-briefs
- P1 parallel doc spine: zesty-ram-316 (#1769) — regen_lens audit via
  PR #1806 + Sub2/Sub3 brief threads
- P4 bridge appendix: warm-ant-877 (#1770) — grep/ledger hygiene against
  bridge_ledger.dag / r3_bridge_retirement_ledger_zero.dag / verification.dag
- P5 F2+F8: PB Mgr coordinates consumer-side with Substrate S12 owner
  (no duplicate PR unless PM ratifies co-author shape)
- P2 T-FixedPoint: HOLD until P1 + SG-0 zero per F1 sequencing
- P3 T-V2-Retirement: HOLD on broad ~79 .rs sweep until P2 + LP +
  Int<N> triggers clear

§2.2 sequencing authority RATIFIED as HARD DAG (PM disposition 2026-05-06):
Per PB Mgr's surface — "staffing parallelism vs hard DAG" question
explicitly resolved. r3-structure.md §"Lane structure" → T-FixedPoint row
names "R2-close dependency: SG-0 zero from T-LensProducer-Retirement" as
explicit dependency. SG-0 zero is structural precondition for T-FixedPoint
(bit-identical compile requires no remaining hand-Rust ratchet); not just
resource sequencing.

T-FixedPoint cannot complete until T-LP-Retirement completes. Plan §2.2
sequence is canonical authority on this; PB Mgr's HOLD on P2 is correct
discipline.

Net: 4 of 6 Mgrs (Substrate + Verification + Debt-Paydown + PB) engaged
substantively with worker pins + ratification surfacing. PB Mgr's HARD-DAG
ratification ask resolved inline.

* docs(r3): absorb Grounding Mgr §5 partition — G4 DISPATCHED + G1/G2/G3/G5 HELD on Substrate cascade

Per Grounding Mgr partition response at gunbc#846 #issuecomment-4385080863.
Fifth Mgr to engage substantively.

§5 header carries Grounding Mgr's worker partition table. Clean dispatch
shape — Grounding lane is largely consumer of Substrate work, so most
items HELD until Substrate carriers land.

Partition:
- G1 L6 row population: HELD pending Substrate S6 EmissionPathProjection
- G2 T-Ground-Rust full coverage: HELD pending Substrate S7 PR-F + S8
  Float migration; #1783 remains draft as dispatch-guide staging artifact
- G3 Coercion-Fold scratch retirement: HELD pending LanguageSpec projection
- G4 F10 install_hint cleanup: DISPATCHED 2026-05-06 to silent-badger-711
  (#1774)
- G5 Anthropic #1702 re-dispatch: HELD pending Substrate S5 variant-aware
  projection + Q-Anthropic-Variant-Aware closure-scope

No PM/Director ratification needed; G4 dispatched cleanly. Other items
proceed when Substrate triggers land.

Net: 5 of 6 Mgrs (Substrate + Verification + Debt-Paydown + PB +
Grounding) substantively engaged. Pending: Evaluator only.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(r3): absorb Evaluator Mgr §4 partition — E1 DISPATCHED + E5 DONE; ALL 6 of 6 Mgrs engaged

Per Evaluator Mgr partition response at gunbc#846 #issuecomment-4385081532.
**Sixth and final Mgr to engage substantively** — all 6 of 6 R3 Mgrs now
have lane-specific worker partitions in design schedule.

§4 header carries Evaluator Mgr's worker partition table:
- E1 E6-G0d constructor execution: DISPATCHED 2026-05-06 to valiant-carp-10
  (#1767); evaluator-only src/v3/compiler/src/lib.rs; brief = #1784
- E2 E5 Descent termination contract consumer: HELD pending Substrate
  carrier landing (quick-koi/quick-crab path)
- E3 E6-G1.a static lens fold: HELD pending Director Q-PAFS /
  Q-EVAL-Lens-Fold-First-Slice countersignature
- E4 E6-G1.b generic dispatch: HELD post-G1.a + post-Substrate X1.b
- E5 X1.b S1 TransformDispatch coordination: DONE cross-lane status sent
  to Substrate (#1739)

Additional state notes:
- #1784 G0d brief green on fmt/ci/v3; self_host_ratchet in progress
  post-main merge — doesn't block E1 dispatch (brief stable + approved)
- #1799 E5 STOP packet green on fmt/ci/v3; held semantically behind
  Substrate termination contract
- warm-dove #1778 passing/held; existing PR needs Director/PM disposition

No PM/Director ratification needed for E1/E5. E3 still needs Director
countersignature.

Net: 6 of 6 Mgrs (Substrate / Verification / Debt-Paydown / PB / Grounding /
Evaluator) substantively engaged with design schedule. Concrete dispatches
in flight: G4 (silent-badger-711) + DP1 + DP2 (PR #1807) + E1 (valiant-
carp-10) + S5 (quiet-boar-160 in flight) + Substrate Mgr-tier authoring
queue (S1/S2/S3/S9). Cross-lane coord working: E5 → Substrate; G* → S*
trigger-cascade.

Engagement scoreboard: 100% of R3 Mgrs partitioned + dispatching per
schedule. PM micro-management overhead = zero per Mgr-tier dispatch
discipline.

* docs(r3): codex BLOCKING fixes — §S4 audit-first against extdeps.github.actions + §V1 Pattern-A 5th gate routed to T-CostLens

Fix 2 of 4 codex BLOCKING findings on PR #1810:

1. §S4 Workflow* family carriers (Class 4) — prepend existing-ontology audit
   prerequisite citing dsl/extdeps/github/actions.dag (218 lines, already
   declares Workflow / WorkflowTrigger / Job / Step / MatrixStrategy /
   RunnerSpec / WorkflowPermissions / ConcurrencySpec / DispatchInput).
   Reframe proposed carriers as audit targets / deltas, not fresh ontology;
   require Substrate Mgr audit-and-delta receipt before worker dispatch.
   Per feedback_audit_adjacent_authority_first + feedback_parallel_representation_debt.

2. §V1 Pattern-A executable cluster — fix count mismatch. Headline now says
   "4 NEW (DimensionReport-typed cluster) in V1"; explicit note that the 5th
   NEW Pattern-A gate (§1.8 #40 symbolic_cost_expr_equals_executable,
   SymbolicCost-typed) belongs to T-CostLens-Composition lane, not V1's TC
   cluster (per r3-program-plan.md:755 — different predicate family,
   distinct runner work). Closure-predicate citation updated accordingly.

Findings 1 (external PM ledger) + 2 (Mgr-canvas → lane authority) rebutted
on PR with grep evidence — both invalid.

… delta

Per PB Mgr dispatch on inbox #1768 (assignment #1919, cycle #1861):
re-execute §Delta methodology against current origin/main HEAD
2c7d820 after recent bootstrap/substrate churn (Q-MachineConstraint
#1856, T-Numeric S9 #1840, #1807/#1892/#1903 paydown row refreshes,
T-V2 inventory #1848/#1850).

Verdict: no material delta. All audit findings reproduce; all
zero-coverage greps still return zero; B.2 authority-migration markers
in dag.rs still present.

Line-anchor drift summary (vs prior §Delta @ 530c76e):
- induction.dag: meet/join_sub_value -5 lines; int_pow_bounded /
  ceil_log / ceil_log_iter / master_theorem / derive_bound -3 lines
- termination.dag: peano / positive_descent / proportional_divisor
  +103/+105/+106 lines (file grew substantially; symbols still live)
- lib.rs Non-Arrow Callable fail-closed: shifted to :674; new second
  site at :2338 (same fail-closed semantics, different dispatch path)
- lower.rs lower_constructor_invocation: +~89 lines
- B.2 m2 oracle/shim block: structurally identical (no further drift)
- Cargo edges :37-38: unchanged
- dag.rs authority-migration markers: present at :1786-1798 (comment
  block) and :3587-3606 (typed accessor); semantic content unchanged

New §Delta subsection added; freshness pointer at top refreshed to
point to 2c7d820. Prior §Delta (530c76e) + B.2 reclassification
preserved for audit history.

Constraints honored: not S-1 authoring; no src/v2/ edits; no Cargo
edge removal; no code migration.

Re-executed live-on-main methodology vs current origin/main per Mgr dispatch
(inbox #1742). All audit findings reproduce: Pop A substrate live with zero
v3-side test coverage; non-Arrow Callable evaluator arm still parked; Pop B
v2 dependencies and Cargo edges still present. Only drift: minor line-number

* docs(audit): r3-pb tv2 §Delta B.2 reclassification — substrate authority migration already landed (PR #1805 BLOCKING review)

Per blocking review on PR #1805 (codex sha:72667918): the §Delta B.2 row
incorrectly inferred from the surviving v2 oracle that Substrate authority
migration is still pending. Re-grep at HEAD 530c76e shows the migration
already landed:

- src/v3/compiler/src/dag.rs:1789-1791 doc comment names dsl/std/algebra.dag
  as the semantic authority and demotes v2 stage0 to "drift ratchet".
- src/v3/compiler/src/dag.rs:3596-3605 typed accessor reads the lowered
  data kernel_algebra_profile Map directly.
- src/v3/compiler/tests/integration/m2_substrate_inhabitance_test.rs:1239
  v3_kernel_algebra_profile_reads_lowered_dag_map_authority ratchets v3
  reading the lowered-Dag Map authority (P0 invariant).

B.2's remaining R3 PB-lane work is parity-test retirement + Cargo-edge drop,
not authority migration. Net dispatch order corrected: §3.2 collapses to a
PB-lane-internal mechanical retirement; no Substrate-Manager dispatch
needed for B.2 disposition. Pop A gate set unaffected (still
§"Post-#1715 reclassification").

* docs(briefs): sweep bare .md:NNN citations in 3 PB-owned R3 briefs

Per Director #1739 / `brief-authoring-checklist.md` §"Citation
discipline" + PB Mgr dispatch (mirror of Substrate-Mgr sweep at
127287a): replace bare `file.md:NNN` references with section-anchor
form across PB-owned `docs/briefs/r3-pb-*.md`.

Files swept (3 of 4 with bare citations under `r3-pb-*` glob):
- docs/briefs/r3-pb-runtime-equivalence-corpus-seed-audit.md (1)
- docs/briefs/r3-pb-t-fixedpoint-worker.md (3)
- docs/briefs/r3-pb-tier3-perf-budget-worker.md (4)

Conversions:
- `r2-evaluator-manager.md:27` → `r2-evaluator-manager.md` §"Owned
  deliverables (through R2 close)" — "Runtime value model" sub-lane row
- `r3-structure.md:59`, `:60` → `r3-structure.md` §"Lane gating summary"
- `r2-structure.md:296` → `r2-structure.md` §"R1 closure criteria"
  (the "`pb_self_compile_fixed_point` two-horizon semantics" paragraph)
- `r2-pure-bootstrap-manager.md:24` → `r2-pure-bootstrap-manager.md`
  §"Owns (post-R1 R2 program work)" — "Tier 3 mirror dissolutions:
  termination" row (and analogous for :25/:26/:27 → computation /
  induction / effect-carrier rows)
- `r2-pure-bootstrap-manager.md` §"Acceptance" line 101 →
  `r2-pure-bootstrap-manager.md` §"Acceptance"

Verification: `grep -nE '\.md:[0-9]+' <files>` returns zero matches
on the three swept briefs.

Out of scope: docs/briefs/r3-pb-regen-lens-consumer-audit.md (~14
bare citations into external doc/audit corpus) — deferred to a
follow-on sweep so this PR stays small per dispatch shape (≤4 files).

* docs(briefs): sweep bare .md:NNN citations in regen-lens consumer audit

Follow-on to 23274a5 — completes the PB-owned `r3-pb-*.md` sweep.

File: docs/briefs/r3-pb-regen-lens-consumer-audit.md (4 cells across
"Documentation surface (authority chain)" and "Handoff points" tables;
~14 individual bare refs collapsed into stable section anchors).

Drift fix while sweeping: the row at line 90 cited `r3-structure.md:26,
:52, :107` as "T-LensProducer-Retirement sub-gate 3 acceptance"; lines
52 and 107 had drifted off-target ("Lens framework" / `anthropic_wire_*`
respectively). Replaced with the canonical anchors that actually carry
sub-gate 3 acceptance: §"Summary" item 2, §"Acceptance — `.dag` gates"
T-LensProducer-Retirement (`regen_lens_dot_rs_retired` row), and
§"Lane structure" T-LensProducer-Retirement row.

Verification: `grep -nE '\.md:[0-9]+' docs/briefs/r3-pb-regen-lens-consumer-audit.md`
returns zero matches. `.dag:` and `.rs:` line refs (code citations)
intentionally untouched per dispatch scope.

* docs(briefs): fix two-horizon authority anchor in t-fixedpoint-worker

Address BLOCKING review on PR #1831 (briansrls 2026-05-06T09:25Z).

The previous sweep at 23274a5 preserved a drifted target: bare
`r3-structure.md:59` / `:60` lived in §"Lane gating summary" (the
14-of-18 evaluator-gating roll-up), but the brief was citing them as
authority for the `pb_self_compile_fixed_point` two-horizon semantics.
That authority actually lives at r3-structure.md:89-90 under
§"Acceptance — `.dag` gates" T-FixedPoint entry, "Two-horizon
clarification" sub-bullet. Sweep preserved the drift instead of fixing
it — same failure class as the r3-structure.md:52/:107 drift caught in
10e0355 on the regen-lens audit.

Conversions (3 sites in the brief, all corrected):
- §"Two-horizon framing": cite §"Acceptance — `.dag` gates"
  T-FixedPoint entry ("Two-horizon clarification" sub-bullet)
- §"Acceptance gate (`.dag`)" intro: cite §"Acceptance — `.dag` gates"
  T-FixedPoint entry (`pb_self_compile_fixed_point` row + Two-horizon
  clarification)
- "Two-horizon authority" footer cross-ref: same anchor

Verification: `grep -n "Lane gating summary" docs/briefs/r3-pb-t-fixedpoint-worker.md`
→ 0 matches. `grep -nE '\.md:[0-9]+' docs/briefs/r3-pb-*.md` → 0 matches.

* docs(audit): T-V2-Retirement mechanical inventory refresh @ 2d26ed2

Per PB Mgr dispatch on inbox #1768 (sleek-eagle-514). Refreshes the
per-surface inventory from `docs/audit/t-v2-retirement-migration-matrix.md`
§2 against current `origin/main` HEAD.

Docs-only; no code touched. No `src/v2/` deletion, no Cargo edge
removal. Inventory + grep receipts only.

Findings (refresh-class only — structural map unchanged):
- Population A: 15 → 16 files (new: pb_method_template_projection_
  consumability.rs). Same G-2 unit-retirement disposition.
- Population B test-file line citations drifted (m2 L991→L1209 etc.);
  Cargo edge citations drifted (Cargo.toml L32-33 → L37-38). Constructs
  unchanged.
- Population C dag.rs line set drifted (6 → 1 doc-comment at L1793).
- 10 additional cosmetic files surfaced (gap-fill vs matrix §2.3).
- Root `Cargo.toml` v2 references (L6/L8/L58/L61) inventoried — not
  previously listed in matrix.
- G-1 closure surface count: 4 (unchanged). No new substantive
  v2_compiler consumer since matrix authoring at 66edec5.

Cross-links every Population B/C row to migration-matrix § + S-1
input-packet decision row.

* docs(audit): fix reproducible grep command in T-V2 inventory

Address codex APPROVE_WITH_COMMENTS on PR #1848 (sha 6526307):
the matrix-cited reproduction command `grep -rEln '...' src/ tests/`
emits `grep: tests/: No such file or directory` because this repo has
no top-level `tests/` (Rust integration tests live under

Replaced with `src/`-only form (same match set, runs cleanly). Added

(1) Search authority was split across narrower greps. The matrix-cited
`\bv2_compiler(_tests)?\b` only matches underscored module paths
(v2_compiler / v2_compiler_tests) and misses the hyphenated Cargo dep
names (v2-compiler / v2-compiler-tests). Receipts in §1.2 B.2 used a
separate Cargo-only grep to compensate, but the cited "search authority"
header didn't reflect that. Replaced with a single unified census:

    grep -rEln 'src/v2/|\bv2[-_]compiler(_tests|-tests)?\b' src/ Cargo.toml dsl/

This catches every surface in one pass. Also surfaced one missed file
under the broader pattern: `dsl/gunbc/tools/ci_runner.dag:16`
(doc-comment with `cargo run -p v2-compiler` invocation example).

(2) `.dag` configuration-data refs were misclassified as Population C
cosmetic. `dsl/gunbc/compiler.dag:53`
`data compiler_source: SourceRoot = { path: "src/v2" }` is a typed
data declaration consumed by the compile pipeline — silently rewriting
it during a cosmetic G-2 sweep would either invalidate `compiler_source`
or quietly retarget the compile root without an authoring-time decision.
Reclassified as a new C-data row (§1.3 C.3) with named G-2 routing
to S-1 (input-packet Decision 6 scope coverage) rather than C-cosmetic
"sweep at G-2" default.

Net G-1 closure surface count: still 4 (unchanged).

* docs(audit): inventory line-completeness + 2nd C-data row (compiler.dag:270)

Address codex BLOCKING inline review on PR #1848 at line 10.

Reviewer claimed the unified grep `\bv2[-_]compiler(_tests|-tests)?\b`
misses three sites; verified directly: regex catches all three. The
substantive issue is **inventory line-completeness**, not regex
coverage — earlier passes enumerated FILES not all line-hits within
files.

Fixes:
- Population B `p0_std_render_repeat_string_test.rs`: add L25 body-of-
  test call to `v2_compiler::v2_std_core::diagnostic_to_message`
  (matrix §3.1 only listed `use`-decls L9-L11; this is a 4th
  substantive line in the same file). Same Decision 1 disposition.
- Population C `pb_method_template_projection_dag_emit_test.rs`: add
  L24 (was L28/L54).
- Population C `SELF_HOSTING.md`: add L1178 (`cargo test -p
  v2-compiler-tests ci_freshness` doc reference).
- Population C-data: add 2nd row, `dsl/gunbc/compiler.dag:270`
  `data test_package: NonEmptyStr = "v2-compiler-tests"` — typed
  config naming the Cargo test crate, tied to Cargo edge §B.2
  retirement. Same C-data class as compiler.dag:53; routed to S-1.

Net G-1 closure surface count: still 4 (unchanged — L25 is in an
already-counted Population B file).

* docs(audit): correct compiler.dag:270 routing — G-2 package, not G-1 edge

Address codex BLOCKING on PR #1850 (sha 15faffa): the C-data row at
`dsl/gunbc/compiler.dag:270` (`test_package = "v2-compiler-tests"`)
was incorrectly tied to §B.2 Decision 3 (G-1 dev-dep edge retirement).
That conflates two distinct removals:

- G-1 / §B.2 Decision 3: deletes the dev-dep edge in
  `src/v3/compiler/Cargo.toml` — consumer-side dependency removed,
  but the `v2-compiler-tests` Cargo package itself still exists at
  workspace root.
- G-2 / root workspace removal: deletes `src/v2/tests` workspace
  member (§1.4 root Cargo.toml L8) — the published package name
  goes away.

The data row points at a *package name*, which remains valid post-G-1
and only becomes stale at G-2. Re-routed to a separate S-1 G-2
decision (CI test package retargeting), explicitly not tied to
B.2/Decision 3. Updated both §1.3 C.3 row and §2 cross-ref row to
reflect the correction.

Per PB Mgr dispatch on inbox #1768 (assignment #1890): re-run §Verified
row-#1 receipts against latest origin/main HEAD.

Re-verification at HEAD 831080d (2026-05-06):
- rg for `regen_lens_main` / `*_main -> ProcessExit` entry: no match
  (NOT-LIVE unchanged)
- ls dsl/std/runtime/bin_shims/: README.md only (framework-only,

+ a re-verification note acknowledging the HEAD delta (#1503 PR-E E7,

* docs(briefs): T-V2 population audit §Delta (2026-05-06) — no material delta

Per PB Mgr dispatch on inbox #1768 (assignment #1919, cycle #1861):
re-execute §Delta methodology against current origin/main HEAD
2c7d820 after recent bootstrap/substrate churn (Q-MachineConstraint
#1856, T-Numeric S9 #1840, #1807/#1892/#1903 paydown row refreshes,
T-V2 inventory #1848/#1850).

Verdict: no material delta. All audit findings reproduce; all
zero-coverage greps still return zero; B.2 authority-migration markers
in dag.rs still present.

Line-anchor drift summary (vs prior §Delta @ 530c76e):
- induction.dag: meet/join_sub_value -5 lines; int_pow_bounded /
  ceil_log / ceil_log_iter / master_theorem / derive_bound -3 lines
- termination.dag: peano / positive_descent / proportional_divisor
  +103/+105/+106 lines (file grew substantially; symbols still live)
- lib.rs Non-Arrow Callable fail-closed: shifted to :674; new second
  site at :2338 (same fail-closed semantics, different dispatch path)
- lower.rs lower_constructor_invocation: +~89 lines
- B.2 m2 oracle/shim block: structurally identical (no further drift)
- Cargo edges :37-38: unchanged
- dag.rs authority-migration markers: present at :1786-1798 (comment
  block) and :3587-3606 (typed accessor); semantic content unchanged

New §Delta subsection added; freshness pointer at top refreshed to
point to 2c7d820. Prior §Delta (530c76e) + B.2 reclassification
preserved for audit history.

Constraints honored: not S-1 authoring; no src/v2/ edits; no Cargo
edge removal; no code migration.

Re-executed live-on-main methodology vs current origin/main per Mgr dispatch

* docs(audit): r3-pb tv2 §Delta B.2 reclassification — substrate authority migration already landed (PR #1805 BLOCKING review)

Per blocking review on PR #1805 (codex sha:72667918): the §Delta B.2 row
incorrectly inferred from the surviving v2 oracle that Substrate authority
migration is still pending. Re-grep at HEAD 530c76e shows the migration
already landed:

- src/v3/compiler/src/dag.rs:1789-1791 doc comment names dsl/std/algebra.dag
  as the semantic authority and demotes v2 stage0 to "drift ratchet".
- src/v3/compiler/src/dag.rs:3596-3605 typed accessor reads the lowered
  data kernel_algebra_profile Map directly.
- src/v3/compiler/tests/integration/m2_substrate_inhabitance_test.rs:1239
  v3_kernel_algebra_profile_reads_lowered_dag_map_authority ratchets v3
  reading the lowered-Dag Map authority (P0 invariant).

B.2's remaining R3 PB-lane work is parity-test retirement + Cargo-edge drop,
not authority migration. Net dispatch order corrected: §3.2 collapses to a
PB-lane-internal mechanical retirement; no Substrate-Manager dispatch
needed for B.2 disposition. Pop A gate set unaffected (still
§"Post-#1715 reclassification").

* docs(briefs): sweep bare .md:NNN citations in 3 PB-owned R3 briefs

Per Director #1739 / `brief-authoring-checklist.md` §"Citation
discipline" + PB Mgr dispatch (mirror of Substrate-Mgr sweep at
127287a): replace bare `file.md:NNN` references with section-anchor
form across PB-owned `docs/briefs/r3-pb-*.md`.

Files swept (3 of 4 with bare citations under `r3-pb-*` glob):
- docs/briefs/r3-pb-runtime-equivalence-corpus-seed-audit.md (1)
- docs/briefs/r3-pb-t-fixedpoint-worker.md (3)
- docs/briefs/r3-pb-tier3-perf-budget-worker.md (4)

Conversions:
- `r2-evaluator-manager.md:27` → `r2-evaluator-manager.md` §"Owned
  deliverables (through R2 close)" — "Runtime value model" sub-lane row
- `r3-structure.md:59`, `:60` → `r3-structure.md` §"Lane gating summary"
- `r2-structure.md:296` → `r2-structure.md` §"R1 closure criteria"
  (the "`pb_self_compile_fixed_point` two-horizon semantics" paragraph)
- `r2-pure-bootstrap-manager.md:24` → `r2-pure-bootstrap-manager.md`
  §"Owns (post-R1 R2 program work)" — "Tier 3 mirror dissolutions:
  termination" row (and analogous for :25/:26/:27 → computation /
  induction / effect-carrier rows)
- `r2-pure-bootstrap-manager.md` §"Acceptance" line 101 →
  `r2-pure-bootstrap-manager.md` §"Acceptance"

Verification: `grep -nE '\.md:[0-9]+' <files>` returns zero matches
on the three swept briefs.

Out of scope: docs/briefs/r3-pb-regen-lens-consumer-audit.md (~14
bare citations into external doc/audit corpus) — deferred to a
follow-on sweep so this PR stays small per dispatch shape (≤4 files).

* docs(briefs): sweep bare .md:NNN citations in regen-lens consumer audit

Follow-on to 23274a5 — completes the PB-owned `r3-pb-*.md` sweep.

File: docs/briefs/r3-pb-regen-lens-consumer-audit.md (4 cells across
"Documentation surface (authority chain)" and "Handoff points" tables;
~14 individual bare refs collapsed into stable section anchors).

Drift fix while sweeping: the row at line 90 cited `r3-structure.md:26,
:52, :107` as "T-LensProducer-Retirement sub-gate 3 acceptance"; lines
52 and 107 had drifted off-target ("Lens framework" / `anthropic_wire_*`
respectively). Replaced with the canonical anchors that actually carry
sub-gate 3 acceptance: §"Summary" item 2, §"Acceptance — `.dag` gates"
T-LensProducer-Retirement (`regen_lens_dot_rs_retired` row), and
§"Lane structure" T-LensProducer-Retirement row.

Verification: `grep -nE '\.md:[0-9]+' docs/briefs/r3-pb-regen-lens-consumer-audit.md`
returns zero matches. `.dag:` and `.rs:` line refs (code citations)
intentionally untouched per dispatch scope.

* docs(briefs): fix two-horizon authority anchor in t-fixedpoint-worker

Address BLOCKING review on PR #1831 (briansrls 2026-05-06T09:25Z).

The previous sweep at 23274a5 preserved a drifted target: bare
`r3-structure.md:59` / `:60` lived in §"Lane gating summary" (the
14-of-18 evaluator-gating roll-up), but the brief was citing them as
authority for the `pb_self_compile_fixed_point` two-horizon semantics.
That authority actually lives at r3-structure.md:89-90 under
§"Acceptance — `.dag` gates" T-FixedPoint entry, "Two-horizon
clarification" sub-bullet. Sweep preserved the drift instead of fixing
it — same failure class as the r3-structure.md:52/:107 drift caught in
10e0355 on the regen-lens audit.

Conversions (3 sites in the brief, all corrected):
- §"Two-horizon framing": cite §"Acceptance — `.dag` gates"
  T-FixedPoint entry ("Two-horizon clarification" sub-bullet)
- §"Acceptance gate (`.dag`)" intro: cite §"Acceptance — `.dag` gates"
  T-FixedPoint entry (`pb_self_compile_fixed_point` row + Two-horizon
  clarification)
- "Two-horizon authority" footer cross-ref: same anchor

Verification: `grep -n "Lane gating summary" docs/briefs/r3-pb-t-fixedpoint-worker.md`
→ 0 matches. `grep -nE '\.md:[0-9]+' docs/briefs/r3-pb-*.md` → 0 matches.

  consumability.rs). Same G-2 unit-retirement disposition.
- Population B test-file line citations drifted (m2 L991→L1209 etc.);
  Cargo edge citations drifted (Cargo.toml L32-33 → L37-38). Constructs
  unchanged.
- Population C dag.rs line set drifted (6 → 1 doc-comment at L1793).
- 10 additional cosmetic files surfaced (gap-fill vs matrix §2.3).
- Root `Cargo.toml` v2 references (L6/L8/L58/L61) inventoried — not
  previously listed in matrix.
- G-1 closure surface count: 4 (unchanged). No new substantive
  v2_compiler consumer since matrix authoring at 66edec5.

shifted to line-level but kept the `l` flag.

Drop `l` → `-rEn`. Added a one-line note explaining the flag
delta vs the matrix-cited form.

* docs(audit): correct compiler.dag:270 routing — G-2 package, not G-1 edge

Address codex BLOCKING on PR #1850 (sha 15faffa): the C-data row at
`dsl/gunbc/compiler.dag:270` (`test_package = "v2-compiler-tests"`)
was incorrectly tied to §B.2 Decision 3 (G-1 dev-dep edge retirement).
That conflates two distinct removals:

- G-1 / §B.2 Decision 3: deletes the dev-dep edge in
  `src/v3/compiler/Cargo.toml` — consumer-side dependency removed,
  but the `v2-compiler-tests` Cargo package itself still exists at
  workspace root.
- G-2 / root workspace removal: deletes `src/v2/tests` workspace
  member (§1.4 root Cargo.toml L8) — the published package name
  goes away.

The data row points at a *package name*, which remains valid post-G-1
and only becomes stale at G-2. Re-routed to a separate S-1 G-2
decision (CI test package retargeting), explicitly not tied to
B.2/Decision 3. Updated both §1.3 C.3 row and §2 cross-ref row to
reflect the correction.

* docs(audit): align §2 cross-ref pb_method_template line set with §1.3

cursor optional nit on PR #1850: §2 cross-reference table listed
`pb_method_template_projection_dag_emit_test.rs:28,54` while
§1.3 C.2 and §3 Δ7 include L24 too. Pure doc hygiene; line set
now consistent (L24,28,54).

* docs(audit): align intro line-citation framing with HEAD-verified note

cursor optional polish on PR #1850: intro said "Every cell below cites
a live grep / file/line on 2d26ed2" while the HEAD verified note
acknowledges follow-up validations after #1848. Aligned the two:
initial cells pinned to 2d26ed2; follow-up additions validated
post-#1848 merge; future refreshes should re-pin HEAD before citing.

* docs(briefs): refresh BinShim row-1 packet HEAD pin (9cf6dd2 → 831080d)

Per PB Mgr dispatch on inbox #1768 (assignment #1890): re-run §Verified
row-#1 receipts against latest origin/main HEAD.

Re-verification at HEAD 831080d (2026-05-06):
- rg for `regen_lens_main` / `*_main -> ProcessExit` entry: no match
  (NOT-LIVE unchanged)
- ls dsl/std/runtime/bin_shims/: README.md only (framework-only,
  unchanged)
- All cited surfaces still resolve at the previously-pinned line
  numbers: process.dag :39 (ProcessExit) / :41 (ExitFailure) / :50
  (exit_failure helper); bin_shim.dag :19 (BinShim type with
  entrypoint_name)

Verdict unchanged: row-#1 NOT-LIVE; Shape A/B/C disposition is still
the head-of-chain blocker. Doc body needed only the HEAD pin refresh
+ a re-verification note acknowledging the HEAD delta (#1503 PR-E E7,
T-Numeric-Construction S9, Q-MachineConstraint #1856, T-V2 inventory
#1848/#1850, etc.) without `regen_lens_main` authoring.

No Shape pick. No regen_lens_main. No carrier/loader edits.

* docs(briefs): T-V2 population audit §Delta (2026-05-06) — no material delta

Per PB Mgr dispatch on inbox #1768 (assignment #1919, cycle #1861):
re-execute §Delta methodology against current origin/main HEAD
2c7d820 after recent bootstrap/substrate churn (Q-MachineConstraint
#1856, T-Numeric S9 #1840, #1807/#1892/#1903 paydown row refreshes,
T-V2 inventory #1848/#1850).

Verdict: no material delta. All audit findings reproduce; all
zero-coverage greps still return zero; B.2 authority-migration markers
in dag.rs still present.

Line-anchor drift summary (vs prior §Delta @ 530c76e):
- induction.dag: meet/join_sub_value -5 lines; int_pow_bounded /
  ceil_log / ceil_log_iter / master_theorem / derive_bound -3 lines
- termination.dag: peano / positive_descent / proportional_divisor
  +103/+105/+106 lines (file grew substantially; symbols still live)
- lib.rs Non-Arrow Callable fail-closed: shifted to :674; new second
  site at :2338 (same fail-closed semantics, different dispatch path)
- lower.rs lower_constructor_invocation: +~89 lines
- B.2 m2 oracle/shim block: structurally identical (no further drift)
- Cargo edges :37-38: unchanged
- dag.rs authority-migration markers: present at :1786-1798 (comment
  block) and :3587-3606 (typed accessor); semantic content unchanged

New §Delta subsection added; freshness pointer at top refreshed to
point to 2c7d820. Prior §Delta (530c76e) + B.2 reclassification
preserved for audit history.

Constraints honored: not S-1 authoring; no src/v2/ edits; no Cargo
edge removal; no code migration.

* docs(briefs): align §Delta grep flags (-rcE → -rnE) per PB Mgr nit on #1926

Rest of the audit file uses `-rnE` (line-numbered output, call-site-
capable per the existing per-row narrative). The new §Delta (2026-05-06)
table inadvertently used `-rcE` (count-only). Aligned with the rest of
the file; flag now consistent across all 8 grep invocations in §A and
§Delta tables.

Non-blocking nit only; no semantic change.

* docs(briefs): clarify markdown-table escape note in §Delta grep cells

Address codex REQUEST_CHANGES on merged PR #1926 (sha c68800f, openai-pro
review 2026-05-07T00:27Z): \`\|\` inside table cells under \`grep -E\` is
ambiguous in raw markdown source — \`\|\` is a markdown-table escape
that renders as \`|\`, but a reader copying the raw source into a shell
would get a literal pipe (no alternation).

Verified both parses at HEAD \`2c7d82031\`:
- as-written (literal \`\|\`): 0 matches
- as-rendered/alternation (\`|\`): 0 matches

The audit's "no material delta" verdict holds under either parse. The
\`\|\` convention is load-bearing across the file (§Population A row
cells at L25/L35/L45/L55, prior §Delta table at L183-186) — so the fix
is to add a clarifying note above the §Delta table explaining the
markdown-table escape, not to break the existing convention.

Followup PR (since #1926 already merged before review arrived).
