docs(evaluator): add E2 descent proof consumer brief - #1854
Conversation
|
Review metadata
Verdict: APPROVE Diff is a narrowly scoped documentation brief, and I don’t see a concrete conflict with the pinned rubric docs. The brief consistently preserves single-authority and fail-closed discipline by keeping termination-proof production in substrate, forbidding evaluator-local inference, and requiring typed residual handling instead of fabricated execution. No testing-discipline violation is introduced by the brief itself. |

1. Story of the diffThis PR adds a single pre-authored worker brief for the future E2 evaluator consumer of descent execution proofs. The brief intentionally does not implement the evaluator change yet: it gates dispatch on a substrate-owned 2. Invariant categories
Compliant — the brief treats the evaluator as an implementation-side consumer and keeps proof production/substrate authority out of scope: “proof producer, evidence lattice, cluster coverage, and per-call evidence broadening remain Substrate-owned” (
Compliant — single-authority and facts-flow-forward are handled by requiring the evaluator to call the substrate-owned proof query rather than infer proof facts locally (
N/A — this diff adds no Rust implementation, APIs, helpers, methods, error types, or module structure to assess against coding conventions.
Compliant — no tests are required in this PR because it is a worker brief only, but the brief correctly requires the future implementation PR to include focused evaluator tests for certified execution, fail-closed residuals, replacement scope, stack restoration, and no local proof-inference path (
N/A — the diff does not alter a locked design surface; it references current substrate/evaluator state as authority and explicitly stops future work from changing parser, lowerer, substrate carriers, runner behavior, or
Compliant — the pre-authored brief is a tracked scaffold: it documents its status and dispatch gate ( 3. VerdictAPPROVE. The PR is a clean documentation/brief addition that preserves substrate authority, fail-closed evaluator behavior, and a bounded future implementation contract. I do not see a diff-line-supported finding against the changed file. |

Root Cause
docs/briefs/r3-pr-e2-descent-proof-consumer-worker.mdstale authority names from an earlier R3/E5 plan were copied into the new brief → replace them with the live authority chain before this worker brief lands.
Non-blocking — Strengths
docs/briefs/r3-pr-e2-descent-proof-consumer-worker.mdThe implementation bars correctly keep the evaluator as a proof consumer and preserve fail-closed descent residual behavior instead of adding local termination inference.

BLOCKING: The Source Authority section names missing docs (r3-pr-e5-loopbound-descent-stop-packet.md and ../r3-program-plan.md), so the worker would dispatch from unverifiable authorities rather than live R3 evaluator/readiness docs (INVARIANTS P1).

Addressed in current head I verified the live authorities exist and updated the section from generic/stale naming to the current chain:
