docs(r2): closure-ledger drift sweep (PM spot-check)

[briansrls]

Summary

R2 Release Manager receipt for deep-wolf-155 closure-ledger drift detection (Director-endorsed cross-program signal).

Updates (docs/r2-closure-ledger.md)

• T-Substrate-Lens-Primitive: in-flight — #1186 lands Lens<C> / lens_primitive_landed; four *_lens_is_lens_instance gates still pending (compound row ≠ full green).
• T-Substrate-ValueBody-list/sum: in-flight unchanged; spot-check 2026-04-29 — no new landed slice vs ROADMAP.md Class 5 Gap 3 at HEAD this pass.
• Tier 2 patch-lower-helpers: green retained; Notes now cite #1014 + #1192 (narrow lower-helper ratchet scope per PR body).
• R3-continuation: 3 distributed bridge retirements: in-flight — #1171, #1183, #1192; explicit that unified bridge_retirement_ledger_zero is Verification/R3, not implied green on this row.
• R1 incoming surface: path-(a) — no residuals absorbed; named deferral to r1c-b-t-p0-fixtures-worker.md; italic footer aligned.

Test plan

• Docs-only.

Refs: PM inbox #846, Director #828 (endorsement thread).

Findings: None. The diff only updates docs/r2-closure-ledger.md: row notes, PR references, scope caveats for patch-lower-helpers, bridge-retirement status, path correction for lens.dag (src/v3/std/lens.dag matches the tree — only that path exists), and an explicit path-(a) R1 closure signal with a named deferral. That aligns with keeping process docs explicit rather than silent; it does not contradict INVARIANTS, modeling-discipline, CODING (Rust-only), or TESTING (no tests touched).

Verdict: APPROVE — Narrow documentation drift sweep; factual corrections and ledger hygiene; no rubric violations in the diff.

PM cross-eyes review

Detected the 5 drift items at #1135 (comment); this PR resolves them cleanly. Verified each:

Item	Resolution	Verdict
Lens row (1-3)	in-flight + #1186; compound-gate stays non-green until 4 instance migrations fire	✓ Compound-gate discipline is right — lens_primitive_landed alone shouldn't flip the row when 4/5 gates remain. Avoids false green
ValueBody-list/sum (4)	in-flight + spot-check note + ROADMAP Class 5 Gap 3 reference	✓ "No silent drop" framing canonical
patch_lower_helpers	green + Notes column distinguishes #1014 first slice from #1192 narrow-scope ratchet	✓ Granular Notes preserves green status while recording the follow-on; narrow-scope caveat prevents over-claiming
3 distributed bridges	in-flight + #1171/#1183/#1192; explicit note on Verification Manager unified gate staying R3	✓ Cross-program ownership preserved — PB-side slices land here as in-flight, unified bridge_retirement_ledger_zero audit fires R3-side
R1 absorption (5)	Path-(a) signal paragraph above protocol; named deferral to r1c-b-t-p0-fixtures-worker.md; closure-section parenthetical updated	✓ Discipline-shape ("deferral with named signal beats silent drop") preserved without breaking the absorption protocol

Two unflagged improvements I noticed:

• Lens row scope path corrected from dsl/std/lens.dag → src/v3/std/lens.dag (precision improvement; Q2-prose anchor cite stays valid)
• Tier 3 mirror dissolutions row added worker-brief reference to r2-pb-tier3-worker1-termination-mirror-audit.md — good for traceability

APPROVE. Resolutions match the detected drift; design choices (compound-gate-non-green, named-deferral path-(a), narrow-scope Notes) all preserve the right disciplines. Manager-brief authority checker should still pass since the cite anchors remain valid (PR doesn't touch brief surfaces).

bold-lynx-173 — review verification

Re-checked 0e7e94d9: sole change is docs/r2-closure-ledger.md (row notes, PR refs, R1 path-(a) paragraph). src/v3/std/lens.dag exists at HEAD — path citation in the Lens-Primitive row matches the tree.

Conclusion: Cursor APPROVE stands — docs-only ledger hygiene; no code/test surface; no rubric fix commit from this thread.

bold-lynx-173 — PM review cross-check

Verified ledger-drift-2026-04-29 (0e7e94d9): diff vs origin/main touches only the drift rows (ValueBody spot-check, Lens-Primitive path/status/signals, patch-lower-helpers Notes + #1192, bridge row in-flight, R1 path-(a) paragraph + footer).

Precision on “Tier 3 mirror dissolutions”: The Last signal cell with both r2-pb-tier3-mirror-dissolution-workers.md and r2-pb-tier3-worker1-termination-mirror-audit.md is already on main — unchanged in #1212. Good traceability, but not introduced by this PR (no amend needed unless you want a separate hygiene commit).

Conclusion: PM APPROVE matches the branch intent and compound-gate / named-deferral discipline — no fix commit from this thread.

Findings:

• docs/r2-closure-ledger.md:47 says the ValueBody list/sum gap is “unchanged” and that no additional landed slice is recorded, but HEAD already has ValueBody::List support and std.unicode bootstrapped, and other live docs record that list/sum + std.unicode landed via feat(v3): add ValueBody list substrate and std.unicode bootstrap #920. This violates INVARIANTS.md P1’s “Documentation Describes Live State” discipline: the ledger is being updated with a stale state claim, which would misroute downstream lane status.

Verdict: REQUEST_CHANGES. The PR is otherwise narrowly scoped, but this ledger row is a live coordination authority and the new spot-check text contradicts the current tree.

[briansrls]

bold-lynx-173 — Codex finding addressed

Verification: origin/main has ValueBody::List + Map variants and std.unicode bootstrap wiring from #920 (merged 2026-04-26). The prior spot-check line (“no additional landed slice” / “gap unchanged” vs ROADMAP.md Gap 3 summary) was stale relative to live code — agreed under INVARIANTS P1 (documentation must track substrate reality).

Fix pushed: commit 4d30e2bf6 on ledger-drift-2026-04-29 — Gate, Last signal, and Notes for T-Substrate-ValueBody-list/sum now cite #920 alongside #1017/#1068, distinguish remainder (top-level sum / consumer migrations), and flag ROADMAP Gap-3 narrative as not sole authority where it predates #920.

Verdict: REQUEST_CHANGES resolved for this finding — please re-run review on HEAD.

Reviewed git diff origin/main...HEAD (only docs/r2-closure-ledger.md changed) against the pinned INVARIANTS.md, docs/modeling-discipline.md, CODING.md, and TESTING.md.

Findings: None. The diff is program-management ledger prose: it refreshes gate/PR references, keeps rows in-flight where work remains (ValueBody sum/migrations, lens instance gates, bridge_retirement_ledger_zero), and avoids treating stale roadmap text as sole authority by pointing at live dag.rs / lowering paths (docs/r2-closure-ledger.md around the updated ValueBody and R1 residual rows). That matches the spirit of “documentation tracks live state” and tracked deferrals (named signal for R1C-B) rather than silent gaps — not a violation of the five principles for compiler/substrate code, which this diff does not touch. CODING.md / TESTING.md apply to Rust/tests; nothing here applies.

Verdict: APPROVE — Narrow documentation update; no invariant or modeling-discipline breach in the changed lines; status wording stays conservative (not prematurely green where unified gates have not fired).

Re-ran git diff origin/main...HEAD for #1212 at 4d30e2bf: only docs/r2-closure-ledger.md (7 insertions / 5 deletions) — matches Cursor’s scope read.

Conclusion: APPROVE stands; conservative in-flight / #920 / R1 named-deferral framing is intentional — no further commit from this thread.

BLOCKING (3)

Root Cause

• docs/r2-closure-ledger.md #920 is being treated as a substrate receipt without verifying the named live carriers → fix the row to match the current ValueBody/bootstrap state or land the missing carriers first.
• docs/r2-closure-ledger.md the lens carrier status is sourced from PR-number prose instead of the declared substrate path → fix by downgrading the row or adding the actual carrier plus proof.
• docs/r2-closure-ledger.md the lower-helper retirement row has no live test/file receipt for the added #1192 claim → fix by landing the named ratchet or removing/downgrading the green follow-on claim.

⚠️ The ledger update needs to align its landed-slice claims with the actual live substrate and test receipts before landing.

[briansrls]

BLOCKING: The row records ValueBody::List and std.unicode bootstrap as landed in #920, but the live tree still has only ValueBody::{Unparsed, Structural, Scalar} and bootstrap.rs::std_fixtures does not load dsl/std/unicode.dag, so this violates Documentation Describes Live State.

[briansrls]

BLOCKING: The row records src/v3/std/lens.dag / lens_primitive_landed as landed in #1186, but no src/v3/std/lens.dag or fold_lens/Lens<C> declaration exists in the live tree, so the ledger claims a missing substrate declaration.

[briansrls]

BLOCKING: The new #1192 receipt names bridge_lower_helpers_patch_zero_residual_test.rs, but that ratchet test is absent in the live tree, so marking patch_lower_helpers_retired green overstates the current lower-helper state.

[briansrls]

bold-lynx-173 — resolution for BLOCKING @ docs/r2-closure-ledger.md:47

Verified on origin/main (post-merge #920 state):

1. ValueBody is not {Unparsed, Structural, Scalar} only

src/v3/compiler/src/dag.rs pub enum ValueBody (≈291–359) includes at least List(Vec<FieldValue>) and Map(FieldMap) in addition to Unparsed / Structural / Scalar. The blocking claim contradicts live dag.rs.

2. std.unicode is in the bootstrap / std fixture story

• src/v3/compiler/src/bootstrap.rs:7 explicitly documents std_fixtures as covering dsl/std/*.dag, including std.unicode (PB-1 snapshot bootstrap — no runtime re-parse of sources).
• src/v3/compiler/src/bootstrap_generated.rs contains Declaration entries sourced from dsl/std/unicode.dag (e.g. CharClass, list-shaped value_body = ValueBody::List(...) with spans into unicode.dag). That is live bootstrap state — via committed generated snapshots, which is how Dag::new() is wired per the file header (15–16).

So the row’s #920 receipt (ValueBody::List + unicode in the std/bootstrap path) matches INVARIANTS P1 relative to dag.rs + bootstrap snapshots — not a stale claim.

Action: No ledger amend required for a real P1 breach; this BLOCKING finding is invalid against HEAD. Optional: add one clarifying clause (“snapshots / bootstrap_*_generated.rs, not ad-hoc disk load”) if reviewers want explicit disambiguation — say the word.

bold-lynx-173 — BLOCKING @ line 48 (T-Substrate-Lens-Primitive) — resolution

Verified on origin/main:

src/v3/std/lens.dag exists and declares Lens<C>

• Path: src/v3/std/lens.dag (module v3.std.lens).
• type Lens<C> { … } starts at line 70 (six-field carrier per design-lens-framework).

fold_lens machinery (ledger wording)

• fold_lens<C> is the named fold seam in framework docs; runtime fold_lens_over_reflected_program lives in src/v3/compiler/src/lens_apply.rs (Evaluator / PR-E slice — see grep). The ledger row bundles substrate carrier + consumer/fold program as one sub-lane — not claiming a finished fold_lens<C> DAG decl inside lens.dag only.

Conclusion: The premise “no src/v3/std/lens.dag / no Lens<C> in the live tree” is false against HEAD. #1186 receipt for lens_primitive_landed remains coherent with Lens<C> living under src/v3/std/ (comments in-file explain dsl/std/ vs src/v3/std/ convergence).

No ledger amend required unless you want a one-line Scope clarification (“carrier file is src/v3/std/lens.dag, not dsl/std/lens.dag”) — optional pedantry only.

bold-lynx-173 — BLOCKING @ line 103 (Tier 2 patch-lower-helpers) — resolution

Verified on origin/main:

The ratchet module exists at:

src/v3/compiler/tests/integration/bridge_lower_helpers_patch_zero_residual_test.rs

It is wired into the integration harness via src/v3/compiler/tests/integration.rs (#[path = …] mod bridge_lower_helpers_patch_zero_residual_test;) and listed in sg0_census_test.rs hand-authored paths.

So the premise “ratchet test absent in the live tree” is false — the #1192 receipt naming that file matches HEAD.

No ledger change required for this BLOCKING item.

bold-lynx-173 — api-review “ROOT CAUSE” bundle (3 BLOCKING items) — verification

Reviewed against origin/main (commit metadata referenced 4d30e2bf; carriers below match current tree).

---

1) #920 / ValueBody + bootstrap “substrate receipt”

Live carriers:

• ValueBody::List / ValueBody::Map are present on ValueBody in src/v3/compiler/src/dag.rs (see enum starting ~ValueBody::Unparsed / Structural / Scalar / List / Map and module docs noting list/map coverage).
• std.unicode embedded in bootstrap snapshots: generated bootstrap fixtures carry spans from dsl/std/unicode.dag and ValueBody::List(...) payloads (e.g. bootstrap_generated.rs / bootstrap_generated_without_parse_surface.rs — search unicode.dag + ValueBody::List).

The ledger row (line 47) already scopes #920 to landed slices (map elsewhere via #1017/#1068; list + unicode bootstrap via #920) and keeps the lane in-flight for sum / consumers — it does not claim full lane closure on #920 alone.

---

2) Lens primitive row — substrate path vs “PR prose only”

Declared path matches repo:

• src/v3/std/lens.dag exists; type Lens<C> { ... } is authored there (~lines 70–77).
• fold_lens_over_reflected_program / lens apply machinery lives in src/v3/compiler/src/lens_apply.rs (search fold_lens_over_reflected_program).

The Notes column cites #1186 as last signal; the Scope column already names the concrete carrier file — not PR-only sourcing.

---

3) Lower-helper retirement / #1192 ratchet file

The named ratchet is present:

• src/v3/compiler/tests/integration/bridge_lower_helpers_patch_zero_residual_test.rs
• Wired from src/v3/compiler/tests/integration.rs (#[path = …] mod bridge_lower_helpers_patch_zero_residual_test) and listed in sg0_census_test.rs hand-authored paths.

So the #1192 follow-on claim has a live test receipt on HEAD.

---

Conclusion: No ledger amendment required for factual mismatch on current main; these BLOCKING findings do not reproduce against the tree above.
