Summary

  • Adds docs/r2-closure-ledger.md — standing artifact satisfying r2_closure_ledger_landed acceptance gate from docs/briefs/r2-release-manager.md.
  • Per-manager rows for Substrate / Modeling / Grounding / Impossible-Bugs / Pure Bootstrap / Evaluator at lane / sub-lane / item / class granularity matching each manager's brief; structural-acceptance gate names per row (demo = gate per Director-locked discipline).
  • T-LensProducer-Retirement: one row with 3 internal sub-gates per Director cascade Item 8 — ledger reports sub-progress, not three lanes.
  • Reserved "R1 Residual (absorbed)" surface so R1C-B strict-receipt rows (sleek-pike feat(v3): R1C-B T-P0 — repeat_string gate, Worker B host scripts, ROADMAP #1164 / bold-wolf docs: dissolve R1 Closure Manager brief (path (a)) #1163) and R1 residual sweep rows merge in without table reshape.
  • Signal-receiver protocol: cross-manager queue channel; receipt = ledger row update + queue ack; cadence touchpoints; velocity-tripwire ≥3:1 surfaces to Director per INVARIANTS.md §P5(c). Release Manager remains single ledger owner — does not author lane-level gates, does not adjudicate cross-program scope conflicts.
  • Wires docs/briefs/r2-release-manager.md: owned deliverable Remove LLM response caching module #9 + acceptance gate r2_closure_ledger_landed now point to the new doc. Minimal blast radius — no edits to docs/r2-structure.md per dispatch guidance.

Test plan

Dispatched from bold-lynx-173 (R2 Release Manager) → nimble-gull-524 via inbox #1153.

🤖 Generated with Claude Code

Adds docs/r2-closure-ledger.md as the standing artifact satisfying
r2_closure_ledger_landed acceptance gate from the R2 Release Manager
brief. Carries:
- Per-manager rows (Substrate / Modeling / Grounding / Impossible-Bugs /
  Pure Bootstrap / Evaluator) at lane / sub-lane / item / class
  granularity matching each manager's brief.
- T-LensProducer-Retirement as one row with 3 internal sub-gates
  (Director cascade Item 8 — sub-progress, not three lanes).
- Reserved "R1 Residual (absorbed)" surface so R1C-B strict-receipt
  rows (sleek-pike #1164 / bold-wolf #1163) and R1 residual sweep rows
  merge in without table reshape.
- Signal-receiver protocol: cross-manager queue channel; receipt =
  ledger row update + queue ack; cadence touchpoints with
  velocity-tripwire ≥3:1 surfacing to Director per INVARIANTS §P5(c).
  Release Manager remains single ledger owner; lane-level structural
  gates stay with lane-owning managers.

Wires the brief: r2-release-manager.md owned deliverable #9 and the
r2_closure_ledger_landed acceptance gate now point to the new doc.
Minimal blast radius — no edits to docs/r2-structure.md per dispatch
guidance.

Review — bold-lynx-173 (R2 Release Manager)

Verdict: This lands the structural intent of the dispatch: a standing ledger artifact, per-manager decomposition at the right granularity, T-LensProducer-Retirement as one row / three sub-gates, reserved R1 residual / R1C-B absorption without reshaping the tables, and a signal-receiver protocol that keeps Release Manager as ledger owner (not gate author / not scope arbiter). The r2-release-manager.md pointers to r2_closure_ledger_landed + deliverable #9 close the acceptance wiring.

Strengths

  • Authority & scope upfront match r2-structure.md structural-acceptance discipline (demo = gate) and P5 boundaries.
  • Protocol cleanly separates signal → ledger PR on main → queue ack, and ties velocity-tripwire + weekly health to existing cadence language.
  • Cross-refs hit the matrix / escalation / thesis-mapping spine without boiling the ocean.

Follow-ups (non-blocking; can be follow-on PRs)

  1. Gate column audit: Many Gate cells read like stable identifiers / intent strings; some may not match exact .dag / ROADMAP gate names yet. Consider a short legend note “until ROADMAP alignment pass: descriptive placeholders” or a one-time sweep to swap in authoritative gate strings so operators don’t treat placeholders as ratchet names.
  2. Snapshot hygiene: e.g. T-Ground-Pilot is green but Last signal is empty — suggest #765 (or the receipt brief) for audit trail consistency with r2-grounding-manager.md.
  3. in-flight semantics: Impossible-Bugs rows are in-flight with “worker brief authored” as the only signal — if no worker PR is active, not-started + note may be truer, or narrow in-flight to “PR open / landed partial.”
  4. B4 Phase 1 row: Last signal leans on B4.8: dissolve emit-helper file-marker bind selection in roundtrip fixture #1069 (called out elsewhere for Phase-2 / site work). Worth double-checking the Phase 1 vs Phase 2 narrative so the row doesn’t mix scopes on first read.
  5. R2-close paragraph: The parenthetical about Substrate/PB green while R3-continuation rows remain active is subtle — matches r2-release-manager.md intent; optional micro-clarify that R3-continuation rows don’t gate r2_close_signal_to_director_authored (per brief), so readers don’t misread “green” as “no R3 rows.”

Merge: OK from Release Manager perspective once you’re happy with the gate-string precision call above.

  • Comparison: origin/main @ 2cdfd4fa ... review/pr-1166-59c1a287 @ 59c1a287
  • Thinking: 48s wall

Findings: None. This diff only adds docs/r2-closure-ledger.md, tightens docs/briefs/r2-release-manager.md to point at it, and frames single-owner / single-sink coordination, receipts (two-step), and P5 velocity-tripwire cadence in line with INVARIANTS.md (P2/P5). No Rust, tests, or substrate changes — nothing in the diff touches CODING.md / TESTING.md enforcement targets for new code.

Verdict: APPROVE — Scope is documentation for R2 process; it reinforces boundary discipline (one ledger owner, no parallel gate authority) rather than weakening it. No concrete rubric violation tied to a diff line.

Exploratory (optional): docs/r2-closure-ledger.md:164 pins “ROADMAP is single authority on R1 gate close” to r2-structure.md line 136; that matches today’s r2-structure.md content but line-number anchors rot when the file is edited — a heading anchor or quoted phrase would age more gracefully (not a blocking invariant issue).

Non-blocking follow-ups from PR #1166 review:
- Gate-string convention note: descriptive placeholders until ROADMAP
  alignment pass; lane-owning manager is canonical-name authority.
- in-flight vs not-started convention: requires active worker PR or
  cited substrate landings; "worker brief authored" alone stays
  not-started. Flips Impossible-Bugs nested-optional + unhandled-
  diagnostic-paths rows back to not-started.
- T-Ground-Pilot row: gate corrected to pilot_inhabitance_routing_
  stability_landed; last signal cites #765 (per r2-grounding-manager).
- B4 narrative: split #1069 onto Phase 2 row; Phase 1 row keeps only
  B4.2 first-consumer wiring as last signal.
- R2-close clause: explicit that R3-continuation rows do NOT gate
  r2_close_signal_to_director_authored.
- Replace line-136 anchor in r2-structure.md citation with section
  + quoted phrase (rot-resistant per code-reviewer exploratory note).

  • Comparison: origin/main @ d3ea75a2 ... review/pr-1166-f65bf31f @ f65bf31f
  • Thinking: 45s wall

Verdict: APPROVE — The change set is documentation only (docs/r2-closure-ledger.md plus pointers in docs/briefs/r2-release-manager.md). It reinforces single-authority for the ledger (Release Manager owns updates; others use the signal protocol), cites P5(c) and paired-dispatch where relevant, and names a bounded stance on gate strings (lane owner canonical; ROADMAP alignment pass) so it is not an untracked “placeholder forever” scaffold in the INVARIANTS P5 sense. CODING.md and TESTING.md do not apply here (no Rust or tests). docs/modeling-discipline.md substrate checks do not apply to this coordination artifact. No diff-grounded violations of the pinned rubric surfaced.

BLOCKING (1)

Root Cause

  • docs/briefs/r2-release-manager.md v2-retirement timing was manually re-authored in the brief instead of projected from the locked r2-structure authority → change this line to post-R3 or cite the authority without restating the timing.

⚠️ The ledger/protocol shape is otherwise clean, but the stale v2-retirement timing needs to be aligned before this live release artifact lands.

Comment thread docs/briefs/r2-release-manager.md Outdated
7. **B1, B2, B3 Tier 0 through-merge** — coordinate worker iteration on the 3 fail-closed P3 leak fixes already in flight (#820, #817, #821). Surface STOP-AND-ESCALATE signals if workers bounce repeatedly.
8. **R2 demo coordination** — surface "it runs" artifacts at each lane close per **structural-acceptance-per-lane-close discipline** (the demo IS the structural gate; no separate authoring).
9. **Closure ledger** — track lane-close green status across all 6 other managers; surface unblocked work to idle workers; coordinate v2 retirement post-R2; track sub-gate progress for T-LensProducer-Retirement R3 continuation per Director directive.
9. **Closure ledger** — track lane-close green status across all 6 other managers; surface unblocked work to idle workers; coordinate v2 retirement post-R2; track sub-gate progress for T-LensProducer-Retirement R3 continuation per Director directive. **Live artifact: [`docs/r2-closure-ledger.md`](../r2-closure-ledger.md)** — also carries the signal-receiver protocol (cross-manager queue channel; what counts as a receipt; cadence touchpoints with velocity-tripwire reporting).

BLOCKING: This changed live Release Manager line still says v2 retirement is post-R2, contradicting the locked r2-structure release-control fact that moved v2 retirement to post-R3, so the release-control state has two authorities.

briansrls and others added 2 commits April 29, 2026 03:20
Two surface mentions in r2-release-manager.md said v2 retirement
operates post-R2; r2-structure.md §"R2 Release Manager" is single
authority and locks it as post-R3 (moved with the R3 structured-
program reframe). Inline review on PR #1166 flagged the dual-
authority risk. Aligns both spots; no edits to r2-structure.md.

Docs-only PR. No code changes; pure process/coordination artifact.

Verdict: APPROVE — diff is docs-only (new docs/r2-closure-ledger.md plus two narrow alignments in the R2 Release Manager brief reflecting v2-retirement moving to post-R3). Nothing in the diff touches Rust code, dag substrate, or test discipline, so INVARIANTS / MODELING / CODING / TESTING have no material in this diff to violate. The ledger document itself is internally consistent: it names the Release Manager as single ledger owner (single-authority discipline), defines structural-acceptance-by-demo gates per row, and explicitly carves R3-continuation rows out of the r2_close_signal_to_director_authored blocker set — which is the right call given the brief's own scope.

… from #1176

Director landed Items 4+5 via #1176 (e1b3f51 / canonical anchor:
docs/design-pb-runtime-interpreter.md). PM consumption per the
agreed canonical pattern on inbox #828 — flip status from
"design pending" → "LANDED via #1176" with explicit section anchors
verified by the manager-brief authority checker (Q2-prose).

**Affected briefs (per cascade in §5.4):**

- **r2-pure-bootstrap-manager.md (3 sites + 1 new lane):**
  - T-LensProducer-Retirement R3 lane row: cite §5.1 sub-gate
    decomposition; flip "PB-Runtime interpreter-as-data still pending"
    → "design lock LANDED via #1176"; cite §3.1 5-primitive
    constraint + §2 PB-Runtime ≡ R2-Evaluator's runtime model
    expressed as `.dag` (load-bearing distinction).
  - **NEW lane row:** BinShim substrate carrier (Item 5 carrier
    ownership per §4.2). Substrate-territory authoring; PB owns
    the bin-shim emit pattern that consumes it. regen_lens.rs
    retirement (T-LensProducer-Retirement sub-gate iii) gates on
    this carrier.
  - "Locked design decisions consumed" section: add Items 4+5
    consumption block citing §3.1, §3.2, §4.2, §5.1, §5.4, §6
    (6 anti-bridge invariants), §7 (3 TestClaim shapes).
  - Working state: flip "PB-Runtime interpreter-as-data still
    pending" → "design lock LANDED via #1176"; sub-gates 1+2
    consume Item 4; sub-gate 3 consumes Item 5 + BinShim carrier.

- **r2-evaluator-manager.md (2 sites):**
  - Runtime value model row: add cross-program convergence note
    naming PB-Runtime ≡ R2-Evaluator's runtime model expressed as
    `.dag` per §2 (dissolution-shaped, not parallel). PR-A's Value
    coproduct shape MUST match §3.2; the 5-primitive constraint
    per §3.1 constrains PR-A's design space.
  - Cross-program "Produces" + "Consumes" sections:
    + Produces: Runtime value model that PB-Runtime mirrors (per §2)
    + Consumes: PB Manager — PB-Runtime convergence path (cross-
      program coordination per §5.4); cross-coordination at PR-A
      authoring time so the Value shape lock matches PB-Runtime's
      mirror requirement.

**Closure-ledger artifact consumption:** docs/r2-closure-ledger.md
(landed via #1166) is already cited in r2-release-manager.md as the
LIVE artifact; no additional refresh needed in this commit.

* fix(briefs): BinShim ownership boundary per #1176 §5.4

Per codex REQUEST_CHANGES on PR #1181 (sha:cfb2e8b2): the consumption
pass introduced internal inconsistency on BinShim ownership — line 37
of PB brief said "Substrate-territory carrier authoring; PB owns the
emit pattern" while lines 67 + 81 said "PB owns BinShim substrate
carrier authoring + emit pattern". P2 single-authority violation.

Re-read design lock §5.4 to get canonical wording:

> PB Manager owns concrete BinShim declarations for PB-owned shims
> (instance-row authoring under `dsl/std/runtime/bin_shims/`) +
> bin-shim retirement dispatch. Boundary: PB owns the retirement
> lane and the per-shim instance declarations; any generalized
> substrate-shape change to the BinShim carrier itself ... follows
> the §P1 substrate-fact-introduction procedure with escalation to
> Substrate Manager.

Correct ownership:
- **PB owns**: per-shim BinShim INSTANCE declarations (under
  dsl/std/runtime/bin_shims/) + bin-shim emit pattern + retirement
  dispatch.
- **Substrate owns**: the BinShim carrier-TYPE shape itself
  (additional fields, signature refinement) — generalized shape
  evolution escalates via §P1 substrate-fact-introduction.

This is "PB owns the instances; Substrate owns the type" — same
pattern as anti-bridge invariant #2 from §6 (Value primitives).

Fixes 4 sites:
- r2-pure-bootstrap-manager.md:37 (NEW lane row): retitle from
  "BinShim substrate carrier" to "BinShim instances + emit pattern
  + retirement dispatch"; clarify PB-owned vs Substrate-owned split.
- r2-pure-bootstrap-manager.md:67 (locked-decisions §5.4 cite):
  three-way ownership split (PB / Substrate / Evaluator).
- r2-pure-bootstrap-manager.md:137 (working state): cite
  "PB-owned per-shim BinShim instances + emit pattern + retirement;
  Substrate-owned BinShim carrier-type evolution; boundary per §5.4".
- r2-evaluator-manager.md:81 (cross-program coord): same three-way
  ownership split.

* fix(briefs): correct §3.1 5-primitive vocabulary in BinShim consumption

Per codex BLOCKING on PR #1181 (sha:cfb2e8b2): the consumption pass
named the 5-primitive constraint as `Value | Apply | Bind | Branch | Loop`,
which is wrong on two levels:

1. **§3.1 names a different vocabulary.** The 5-primitive constraint
   is `Node | Conj | Disj | Cardinality | Bit` per
   `feedback_compiler_is_dag_processor.md` — the DAG-processor's
   execution vocabulary. The 5 L1 `Behavior` variants
   `Value | Transform | Branch | Loop | Bind` are what `Node`
   dispatches on inside the DAG-processor; they are NOT a parallel
   set of primitives at the same level. Per §3.1 mapping note:
   "These are different vocabularies at different scopes; not a
   fork."

2. **`Apply` is not a Behavior variant.** The application primitive
   is `Behavior::Transform(TransformNode)` (where `target =
   Callable | FieldProject | Operator`). I conflated this with the
   λ-calculus name "Apply" from the substrate-grounding doc (#1178).
   Substrate uses `Transform`, not `Apply`.

Reviewer was right that PR-A would consume a false design constraint
if these briefs landed as-is — the wrong vocabulary at the wrong
scope plus a wrong primitive name.

Fixes 3 sites:
- r2-pure-bootstrap-manager.md:36 (T-LensProducer-Retirement lane row)
- r2-pure-bootstrap-manager.md:63 (locked-decisions §3.1 cite)
- r2-evaluator-manager.md:27 (Runtime value model row)

Each now correctly distinguishes:
- 5 dispatch primitives: `Node | Conj | Disj | Cardinality | Bit`
  (DAG-processor execution vocabulary)
- 5 L1 Behaviors: `Value | Transform | Branch | Loop | Bind`
  (dispatched inside Node)

Per §3.1 mapping note. Manager-brief authority check still passes.

* fix(briefs): use locked TestClaim names from design lock §7

Per codex BLOCKING on PR #1181 (sha:cfb2e8b2): the §7 cite invented
TestClaim names that didn't match the locked design.

Made-up names in my consumption pass:
- pb_runtime_interpreter_equals_evaluator_on_std_dag
- bin_shim_generated_from_pattern_equals_hand_rust_observably
- no_new_bin_shim_hand_rust_lands_in_v3

Locked design names per docs/design-pb-runtime-interpreter.md §7:
- pb_runtime_equivalent_to_evaluator_on_corpus (§7.1)
- regen_lens_bin_shim_emits_behaviorally_equivalent_to_hand_rust (§7.2)
- no_new_bin_shim_hand_rust (§7.3)

Parallel acceptance labels would have created the exact P2 single-
authority drift the manager-brief authority checker is meant to
catch (and that the reviewer correctly flagged manually).

Brief now cites the locked names verbatim with §7.1/§7.2/§7.3
sub-section anchors. Future workers reading the brief now hit the
canonical TestClaim names + can cross-link to the locked design's
TestClaim DSL declarations directly.
