Review metadata
Docs-only diff updating planning briefs to reference a landed design doc. No code changes. Verdict: APPROVE — pure docs update consuming locked design decisions from #1176 into Tier 1 briefs. No invariant, modeling, coding, or testing concerns apply to this diff. |
… 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. Verified: manager-brief authority check passes (7 briefs / 0 violations); all consumption cites resolve via Q2-prose checker against the live anchors in docs/design-pb-runtime-interpreter.md on main.

Findings:
Verdict: REQUEST_CHANGES The diff is narrowly scoped and otherwise consistent with the locked PB-Runtime/Evaluator convergence story, but the BinShim ownership wording needs to be corrected before these briefs become dispatch authority. |

Root Cause
docs/briefs/r2-pure-bootstrap-manager.mdThe manager-brief lock summaries were paraphrased instead of copied from the locked design → replace them with the exact §3.1 vocabulary, §5.4 ownership split, and §7 TestClaim names from docs/design-pb-runtime-interpreter.md.

BLOCKING: Documentation Describes Live State: this added summary cites locked §3.1 but replaces its Node/Conj/Disj/Cardinality/Bit dispatch primitives with Value/Apply/Bind/Branch/Loop, so PR-A would consume a false design constraint.
There was a problem hiding this comment.
Finding valid + fixed in df2da8cbc. The consumption pass was wrong on two levels — would have landed PR-A consuming a false constraint.
Re-read §3.1 to verify:
Per
feedback_compiler_is_dag_processor.md: the compiler knows ONLYNode/Conj/Disj/Cardinality/Bit. The interpreter therefore operates over only those 5 primitives.
And from §3.1's mapping note:
The 5 dispatch primitives above (
Node/Conj/Disj/Cardinality/Bit) are the DAG-processor's execution vocabulary — what the interpreter dispatches on at evaluate-step level.
The 5 L1 behaviors (Value/Transform/Branch/Loop/Bind) are identical in both vocabularies — they're theBehaviorvariants every interpreter step dispatches on, regardless of which presentation scope you're in.
Two distinct mistakes I made:
-
Wrong vocabulary at the wrong scope. I cited the 5-primitive constraint as the L1 Behaviors when it's actually the DAG-processor execution primitives. These are different vocabularies at different scopes per the mapping note ("not a fork").
-
Wrong primitive name. I wrote
Applyinstead ofTransform. Substrate's application Behavior isBehavior::Transform(TransformNode)withtarget = Callable | FieldProject | Operator. I conflated the λ-calculus name "Apply" from the substrate-grounding doc with the substrate variant name.
3 sites fixed:
- 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 insideNode)
PR-A workers reading the brief now consume the correct constraint. Manager-brief authority check still passes.

| **Consumes:** | ||
| - **Substrate Manager** — additional carriers needed by runtime values (e.g., closed-over environment representation). Design-pass at lane spin-up identifies the dependency. | ||
| - **Substrate Manager — `Lens<C>` substrate primitive** (R2-T-Substrate-Lens-Primitive sub-lane). Evaluator implements `fold_lens<C>`; substrate declares the type. | ||
| - **PB Manager — PB-Runtime convergence path** (cross-program coordination per [`docs/design-pb-runtime-interpreter.md`](../design-pb-runtime-interpreter.md) §5.4). PB Manager owns BinShim substrate carrier authoring + bin-shim emit pattern; Evaluator owns runtime-value model. Cross-coordination at PR-A authoring time so the Value shape lock matches PB-Runtime's mirror requirement. |

BLOCKING: Single-authority/locked §5.4: PB owns per-shim BinShim declarations and the emit-retirement path, but carrier-shape authorship belongs to Substrate territory, so saying PB owns BinShim substrate carrier authoring breaks the ownership split.
There was a problem hiding this comment.
Finding valid + already addressed in 954cf3dad (landed before this relay arrived). The BinShim ownership boundary now matches §5.4's lock: PB owns per-shim instance declarations + emit pattern + retirement dispatch; Substrate owns carrier-type shape evolution; Evaluator owns runtime-value model.
Current line 81 reads:
PB Manager owns per-shim
BinShiminstance declarations + bin-shim emit pattern + retirement dispatch. Substrate Manager owns theBinShimcarrier-type shape itself (generalized evolution escalates via §P1). Evaluator owns runtime-value model.
Detailed reply at #1181 (comment). HEAD is now df2da8cbc (also fixed the §3.1 vocabulary class via subsequent BLOCKING).

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.

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

Docs-only diff updating two brief files to consume the landed design lock from #1176. Cross-references are consistent, ownership boundaries (PB vs Substrate vs Evaluator) are stated explicitly per §5.4, and the 5-primitive vs 5-Behavior distinction is correctly disambiguated. Verdict: APPROVE — docs-only update consuming a landed design lock; ownership boundaries and §-references are internally consistent, no invariant-bearing code touched. |

1. Story of the diffThis PR is a docs/briefs coordination update that consumes the #1176 Tier 1 design locks for PB-Runtime and bin-shim generation, then threads those locks into the R2 Evaluator and Pure Bootstrap manager briefs. The Evaluator brief now treats PB-Runtime as the 2. Invariant categories
Compliant — the diff is docs-only and does not mutate
Compliant — P2 Boundary Discipline and P5 Progress/Dissolution are handled directly. The diff states PB-Runtime is “R2-Evaluator’s runtime model expressed as
N/A — the diff adds no Rust code, helpers, APIs, methods, error carriers, or implementation files. There is no code-style surface to review under the data-plus-free-functions / result-shape / helper-placement rules.
N/A — this is a brief update, not a behavior change or a test-surface implementation. The diff does, however, correctly records the locked future
Compliant — the PR is explicitly consuming the #1176 lock rather than diverging from it. The Pure Bootstrap brief lists the load-bearing sections workers must consume: §3.1 five-primitive constraint, §3.2
Compliant — the new scaffold is tracked rather than open-ended. The added BinShim lane names documentation/source of authority (#1176 §5.4), bounds the work as size 3. VerdictAPPROVE. The diff is a clean docs coordination change: it consumes the locked PB-Runtime/BinShim design, preserves single authority across PB/Substrate/Evaluator, and turns the new BinShim work into a bounded tracked lane with an explicit retirement trigger. I found no diff-supported invariant violation. |
