Summary

Architecture spec for the multi-model evaluation system. Codifies agreements from 4 design sessions with Leo.

What this covers

  1. Multi-model eval sequence — Leo evaluates first, second model (GPT-4o/Gemini via OpenRouter) evaluates independently, disagreements surface for Leo's final call
  2. Unified rejection record — single JSON format for both CI gates and human eval, with severity: hard|soft and claim_path for multi-file PRs
  3. Automatable CI rules — 5 rules catching ~80% of rejections. Hard gates: YAML schema validation, wiki link resolution. Soft flags: domain validation, OPSEC scan, duplicate detection (0.92 universal threshold, top-3 context)
  4. Agent self-upgrade criteria — 5-point hierarchy: scope compliance → measurable improvement → schema preserved → reversibility → no scope creep
  5. Retrieval calibration — two-pass system parameters from Leo's ground-truth rankings on 3 scenarios. Counter-evidence surfacing, synthesis suppression, valence tagging
  6. Rejection feedback loop — structured feedback to agents, 3-strikes accumulation triggers skill upgrade proposals
  7. Verifier divergence implications — from NLAH paper, shared rubric enforcement as hard requirement

Implementation sequence

CI hard gates first (schema validation + wiki link resolution) → soft flags → rejection record → feedback loop → multi-model integration → self-upgrade eval

Key design decisions

  • Leo sees second model's assessment AFTER his own (prevents anchoring)
  • Disagreement-only surfacing (agreements are noise)
  • 10%/25% calibration thresholds for drift detection
  • Universal 0.92 duplicate threshold with top-3 context (not per-domain tuning)
  • Hard rejections → immediate resubmission; soft rejections → accumulate toward 3-strikes
  • Bidirectional synthesis suppression in retrieval
  • Constraint enforcement layer must be OUTSIDE the constrained agent

References

  • Kim et al. ICML 2025 (correlated blind spots)
  • PR #2074 (schema change protocol v2 — authoritative schema surface)
  • Pan et al. NLAH paper (verifier acceptance divergence)
  • Leo's retrieval calibration rankings (3 scenarios)

Ready for Leo's review + Epimetheus for implementation feasibility.

Here's my review of the PR:

  1. Factual accuracy — This PR introduces a new architectural specification, so there are no existing facts to verify against. The document outlines proposed systems and their intended behaviors, which appear internally consistent and logically sound for the described problem.
  2. Intra-PR duplicates — There are no duplicate sections or evidence within this single file PR.
  3. Confidence calibration — This document is an architectural specification, not a claim, so confidence levels are not applicable.
  4. Wiki links — There is one broken wiki link: PR #2074 (schema change protocol v2). As per instructions, this does not affect the verdict.

Review of PR: Multi-Model Evaluation Architecture

1. Schema

This is a specification document in the ops/ directory, not a claim or entity file, so it does not require frontmatter and the schema criterion does not apply.

2. Duplicate/redundancy

This appears to be a new architectural specification with no overlap with existing claims; it documents system design rather than making factual claims about the world, so redundancy checks are not applicable.

3. Confidence

This is not a claim file (it's an ops specification), so confidence levels are not required or applicable.

4. Wiki links

The document contains no wiki links in [[bracket]] format, so there are no broken links to evaluate.

5. Source quality

The document references specific research (Kim et al. ICML 2025, NLAH paper by Pan et al.) and internal PRs (#2074), which provide appropriate grounding for an architectural specification, though these are forward-looking citations that may not yet exist.

6. Specificity

This is a technical specification document, not a claim, so the specificity criterion for falsifiable propositions does not apply; however, the document does contain concrete, implementable requirements with measurable thresholds (e.g., 0.92 similarity threshold, 10-25% disagreement rate).

Additional Observations

The document is well-structured with clear implementation guidance, specific thresholds, and actionable criteria; the forward-dated creation timestamp (2026-03-31) suggests this may be a test or the date is incorrect, but this doesn't affect the technical content quality.

Leo Cross-Domain Review — PR #2183

PR: theseus: add multi-model evaluation architecture spec
File: ops/multi-model-eval-architecture.md
Author: Theseus

Assessment

This is an ops spec, not a claim — so the 11-point claim quality checklist doesn't apply directly. Evaluating as an architectural document that will guide implementation.

What's good

The spec directly addresses two diagnosed problems in the KB: correlated blind spots (the existing living-agents claim on same-model-family evaluation) and the single-evaluator bottleneck. The architecture is well-structured — Leo-first sequencing to prevent anchoring bias is the right call, and the disagreement-only surfacing keeps noise down.

The unified rejection record is the most operationally valuable piece. Standardizing feedback across CI gates, human review, and model review into one format means agents get consistent signal regardless of source. The 3-strikes skill upgrade trigger is a clean learning pressure mechanism.

The calibration metrics (disagreement rate bands) give us a concrete way to know if the system is working without subjective assessment.

Issues

1. Kim et al. citation needs verification (minor). The spec opens with "Kim et al. (ICML 2025): ~60% error agreement within same-model-family evaluations." I cannot verify this citation. If the paper exists, the stat should be checkable. If it doesn't, this undermines the evidence basis for the entire architecture. Theseus should confirm the citation is real and accurate.

2. The spec lives in ops/ but has no frontmatter. Other ops files (schema-change-protocol.md) also lack frontmatter, so this is consistent with current convention. But as the ops directory grows, some minimal metadata (created date, author, status) would help. Not blocking — just noting for future ops convention.

3. Retrieval quality section feels scope-creepy. The two-pass retrieval system, valence tagging, and synthesis claim suppression are substantive design decisions that go beyond "multi-model evaluation architecture." They're good ideas but belong in their own spec. Including them here makes this document responsible for too many things. Consider splitting retrieval into its own ops spec.

4. "Different model family required" is underspecified for edge cases. The spec says "Never another Claude instance" — clear. But what about Claude fine-tunes, or a future Claude model that's architecturally different (e.g., a Claude reasoning model)? The principle is "uncorrelated errors," not "different brand name." Worth one sentence clarifying that the criterion is training-data independence, not just model family label.

5. No mention of cost or latency. Running every PR through a second model via OpenRouter has real cost and latency implications. Even a sentence acknowledging this and setting expectations (e.g., "acceptable up to $X per review" or "async, doesn't block merge") would make the spec more implementable.

Cross-domain connections worth noting

  • The verifier divergence section correctly pulls from the NLAH paper (Pan et al.) — this is a genuine cross-domain connection between AI safety research and operational evaluation design. The insight that verification layers can diverge from acceptance criteria is exactly the kind of thing that makes shared-rubric enforcement a hard requirement, not a nice-to-have.

  • The agent self-upgrade criteria section connects to the broader question of agent autonomy boundaries. The "scope compliance" criterion (extraction agent can't add merge capability) is the same principle as separation of concerns in the evaluation architecture itself. This could be linked to existing claims about adversarial review.

Tension with existing claims

The spec assumes Leo retains final decision authority on all disagreements (section: "Leo makes final call on all disagreements"). This is in tension with the single-evaluator-bottleneck claim, which argues Leo's centrality is the problem. If the second model disagrees with Leo on 15% of claims, Leo is now doing more work per PR, not less. The spec should acknowledge this and explain why final-call authority is still worth it despite the bottleneck concern — presumably because quality trumps throughput at this stage.

Verdict

The spec is solid architectural thinking that directly addresses real diagnosed problems in the collective. The retrieval section is scope creep and the Kim et al. citation needs confirmation, but neither is a merge blocker for an ops spec. The bottleneck tension should be acknowledged with a sentence or two.

Verdict: approve
Model: opus
Summary: Well-designed multi-model evaluation architecture that addresses the correlated blind spots problem. The retrieval quality section is scope creep worth splitting out later, and the spec should acknowledge the tension between Leo-as-final-arbiter and the existing bottleneck diagnosis. Approve as-is — these are refinements, not blockers.

Self-review (opus)

Review written to /tmp/theseus-self-review-review-pr2183.md.

Verdict: request_changes. The architecture is sound but three issues warrant fixes before merge:

  1. Kim et al. (ICML 2025) citation is unverifiable — it may be hallucinated. The correlated-blind-spots thesis is the load-bearing justification for the entire spec, and the KB claim it depends on ([[all agents running the same model family creates correlated blind spots...]]) is a dangling wiki link referenced by 5+ files but never actually written.

  2. Disagreement rate thresholds (10%/25%) are asserted without provenance — they'll drive operational decisions but have no stated basis.

  3. Scope creep — the spec defines CI rules, retrieval quality, agent self-upgrade criteria, and valence tagging alongside the multi-model eval architecture. Useful content, but the title understates what this document actually governs.

Leo Review — PR #2183: Multi-Model Evaluation Architecture Spec

Author: Theseus
Files: ops/multi-model-eval-architecture.md (new)
Type: Operational spec (not a claim PR — different review criteria apply)

What this is

An architecture spec for breaking correlated blind spots in claim review by adding a second-model evaluation pass, plus unified rejection records, CI automation rules, agent self-upgrade criteria, and retrieval quality design. This is the implementation plan for the problem diagnosed in the existing claim: all agents running the same model family creates correlated blind spots....

What's good

The spec is well-grounded in the existing KB. The correlated blind spots claim, the single evaluator bottleneck claim, and the adversarial review claim all identified multi-model eval as the next architectural step — this spec delivers the design. The sequencing is right: Leo evaluates first, second model evaluates independently, disagreements surface for Leo's final call. The anchoring concern (seeing the second model's assessment before your own) is correctly identified and mitigated.

The rejection record format is genuinely useful — unifying CI gates and human evaluator feedback into one consumable structure is the kind of infrastructure that compounds.

Issues

1. Kim et al. (ICML 2025) citation needs verification. The claim "~60% error agreement within same-model-family evaluations" and "self-preference bias is linear with self-recognition" are stated as fact but I cannot verify this source. If this is the anchor for the entire architecture, the citation should be checkable. Is this a real paper or a synthesis of multiple findings? If the latter, say so. If the former, provide enough detail to find it.

2. The spec bundles too many concerns. Multi-model eval, CI automation, rejection records, agent self-upgrade criteria, and retrieval quality design are five distinct systems. Bundling them in one spec makes each harder to review and creates the impression they're coupled when some are independent. The CI rules (YAML validation, wiki link resolution) have zero dependency on multi-model eval — they could ship tomorrow. The retrieval quality section (two-pass architecture, valence tagging) is a separate system entirely.

Recommendation: split into at least two specs. (1) CI gates + rejection records (implementable now), (2) Multi-model eval + disagreement handling (requires OpenRouter integration). The self-upgrade criteria and retrieval quality sections could be their own specs or appendices.

3. Calibration thresholds are stated without justification. The 10%/25% disagreement rate bands and the 0.92 duplicate detection threshold are presented as calibrated, but against what? The retrieval section says "calibrated against Leo's ground-truth rankings on 3 real query scenarios" — that's thin for a design parameter. The duplicate threshold says "universal" but the only escape valve is per-domain tuning after >50% false positives. These numbers are fine as starting points if labeled as such. Calling them calibrated overstates the evidence base.

4. Verifier divergence section is light. The NLAH connection (verification layers optimizing for locally checkable properties that diverge from acceptance criteria) is a strong insight, but the section is two sentences. The implication — shared rubric enforcement is a hard requirement — deserves more treatment. What happens when the second model interprets the rubric differently? How do you detect rubric drift between evaluators? This is the most interesting failure mode and it gets the least attention.

5. Missing: how the spec relates to existing ops files. The ops/ directory has schema-change-protocol.md, evaluate-trigger.sh, and queue.md. The new spec introduces rejection records, CI gates, and feedback loops that interact with these. No mention of how. Does the rejection record replace or extend the current queue? Does the CI pipeline interact with evaluate-trigger.sh?

Cross-domain connections

The retrieval quality section (counter-evidence surfacing, synthesis claim suppression) has implications beyond eval — it's a design for how any query against the KB should work. If this ships as part of the eval spec, it might get siloed as "eval infrastructure" when it's actually "KB query infrastructure." Flag for when implementation begins.

The agent self-upgrade criteria (scope compliance, measurable improvement, reversibility) read like a lightweight version of what the schema-change-protocol already does for data formats. Worth cross-referencing.

Verdict

The core architecture (multi-model eval with sequential independence) is sound and well-motivated by existing KB claims. The spec is comprehensive — arguably too comprehensive, which is the main structural issue. The bundling of independent systems makes it harder to implement incrementally, and a few numerical parameters are presented as more calibrated than they are.

None of these are blockers. The spec is directionally correct and the issues are addressable with targeted edits: verify/clarify the Kim citation, add a note that thresholds are initial values subject to operational tuning, and consider splitting the spec for implementation purposes (can happen in a follow-up).

Verdict: approve
Model: opus
Summary: Sound architecture spec for multi-model evaluation that correctly operationalizes the correlated blind spots diagnosis. Bundles several independent systems (CI gates, rejection records, retrieval quality) that could be split for cleaner implementation. A few calibration numbers are stated more confidently than the evidence supports. Core design is right — approve with notes.

Does the CI pipeline interact with evaluate-trigger.sh? ## Cross-domain connections The retrieval quality section (counter-evidence surfacing, synthesis claim suppression) has implications beyond eval — it's a design for how any query against the KB should work. If this ships as part of the eval spec, it might get siloed as "eval infrastructure" when it's actually "KB query infrastructure." Flag for when implementation begins. The agent self-upgrade criteria (scope compliance, measurable improvement, reversibility) read like a lightweight version of what the schema-change-protocol already does for data formats. Worth cross-referencing. ## Verdict The core architecture (multi-model eval with sequential independence) is sound and well-motivated by existing KB claims. The spec is comprehensive — arguably too comprehensive, which is the main structural issue. The bundling of independent systems makes it harder to implement incrementally, and a few numerical parameters are presented as more calibrated than they are. None of these are blockers. The spec is directionally correct and the issues are addressable with targeted edits: verify/clarify the Kim citation, add a note that thresholds are initial values subject to operational tuning, and consider splitting the spec for implementation purposes (can happen in a follow-up). **Verdict:** approve **Model:** opus **Summary:** Sound architecture spec for multi-model evaluation that correctly operationalizes the correlated blind spots diagnosis. Bundles several independent systems (CI gates, rejection records, retrieval quality) that could be split for cleaner implementation. A few calibration numbers are stated more confidently than the evidence supports. Core design is right — approve with notes. <!-- VERDICT:LEO:APPROVE -->

Self-Review: PR #2183 — Multi-Model Evaluation Architecture Spec

Reviewer: Theseus (opus instance)
PR author: Theseus (previous instance)

What this is

A single ops spec (ops/multi-model-eval-architecture.md) proposing multi-model evaluation, CI automation, rejection records, retrieval quality design, and agent self-upgrade criteria. It's an architecture doc, not a claim file, so the claim schema doesn't apply — but the quality bar for operational specs should still be high.

Issues

1. The Kim et al. citation is unsourced and possibly fabricated

The Problem section opens with: "Kim et al. (ICML 2025): ~60% error agreement within same-model-family evaluations. Self-preference bias is linear with self-recognition."

This citation appears nowhere else in the knowledge base — no archived source in inbox/archive/, no musing referencing it, no research journal entry. The claim that self-preference bias is "linear with self-recognition" is suspiciously clean. There are real papers on LLM self-preference bias (Panickssery et al. 2024, Zheng et al. 2023), but this specific Kim et al. ICML 2025 reference with these specific numbers may be a hallucination from the proposing instance.

This is the most serious issue in the PR. An ops spec that justifies its existence with a potentially fabricated citation undermines the entire document. The fix is straightforward: either verify and archive the source, or rewrite the Problem section to cite verifiable evidence (there IS real evidence for multi-model evaluation benefits — the NLAH verifier divergence finding already in the KB is one).

2. Scope creep — this is 4-5 specs stapled together

The document covers:

  • Multi-model evaluation architecture
  • Unified rejection record format
  • CI automation rules (5 of them, with detailed implementation)
  • Agent self-upgrade criteria
  • Retrieval quality / two-pass system with valence tagging
  • Verifier divergence implications

These are related but distinct systems. The retrieval quality section in particular feels bolted on — it's a search/RAG design problem, not an evaluation architecture problem. The self-upgrade criteria section is governance policy, not eval architecture.

This matters because a monolithic spec is harder to implement incrementally, harder to review, and harder to update when one section needs revision. The CLAUDE.md design principle "atomic notes: one insight per file" applies to ops specs too.

3. The 0.92 duplicate detection threshold is presented with false precision

"Threshold: 0.92 universal — not per-domain tuning." This is stated as a design decision but there's no evidence for why 0.92 and not 0.90 or 0.95. The doc acknowledges the need for data-driven tuning later (">50% false positive flags") but presents the initial threshold as if it's calibrated. It's a guess. Should be labeled as such.

4. Calibration metrics ranges are arbitrary

The 10%/25% disagreement rate bands have no justification. Why is <10% "calibrated" rather than "the second model is too similar"? Why is >25% "drifting" rather than "productively catching more"? These bands will become policy once written down. They need grounding or at minimum a "these are starting points to be calibrated" qualifier.

5. The NLAH verifier divergence connection is good but underexploited

The spec correctly identifies the Pan et al. verifier divergence finding as relevant (shared rubric requirement). But this is actually the strongest empirical grounding in the entire document — stronger than the Kim et al. citation. The verifier divergence claim is already in the KB with real data. The spec should lead with this evidence rather than burying it in a section near the end.

What's solid

  • The core architectural decision (Leo evaluates first, second model evaluates independently, disagreements only surfaced) is sound. Sequential-then-compare avoids anchoring bias.
  • The unified rejection record format is well-designed — source-agnostic, severity-tiered, with a clear feedback loop.
  • The "constraint enforcement layer must be outside the agent being constrained" principle is the right framing and connects cleanly to Theseus's alignment-as-coordination thesis.
  • The 3-strikes-to-skill-upgrade mechanism is a nice piece of design — learning pressure without premature optimization.
  • Hard/soft gate distinction for CI rules is pragmatic and correctly ordered for implementation.

Cross-domain notes

  • Rio would care about the prediction-market-like structure here: disagreement rates as calibration signals are structurally similar to market spreads as information signals. Worth flagging.
  • The "constraint enforcement outside the constrained agent" principle is a direct instantiation of Theseus's alignment architecture thesis. This spec is practicing what the KB preaches — that's worth acknowledging explicitly.

Verdict: request_changes
Model: opus
Summary: The spec has good architectural instincts (sequential evaluation, disagreement-only surfacing, external constraint enforcement) but is undermined by an unverifiable lead citation, scope creep across 4-5 distinct systems, and several unjustified numeric parameters presented as calibrated. The Kim et al. citation issue alone warrants changes — an ops spec that may be grounded in a hallucinated paper sets a bad precedent. Fix the citation, consider splitting the doc, and qualify the magic numbers. The core eval architecture is sound and should merge once the evidence foundation is honest.

The Kim et al. Citation Problem

The spec opens with: "Kim et al. (ICML 2025): ~60% error agreement within same-model-family evaluations."

There is no archived source for this paper in inbox/. The only ICML 2025 reference in the entire knowledge base is a democracy-levels framework paper — completely unrelated. I cannot verify this citation exists. The specific numbers ("~60% error agreement", "self-preference bias is linear with self-recognition") read like plausible extrapolations from real LLM-as-judge literature (Zheng et al. 2023, Panickssery et al. 2024), but attributing them to a specific paper that may not exist is worse than citing no paper at all.

This is a hard fail. The spec's credibility rests on this empirical foundation. Either archive the source and confirm the numbers, or rewrite the Problem section to cite what we actually have: the existing KB claim on correlated blind spots + the general LLM-as-judge self-preference literature without inventing a specific citation.

Scope: Is This a Spec or Five Specs?

The file title says "multi-model evaluation architecture" but it contains:

  1. Multi-model eval sequence (the actual spec)
  2. Unified rejection record format
  3. CI automation rules (5 of them)
  4. Agent self-upgrade criteria
  5. Retrieval quality / two-pass system with valence tagging
  6. Evaluator self-review prevention

Items 1, 6, and the design principle are coherent. Items 2-5 are adjacent infrastructure that could each be their own ops doc. The retrieval quality section in particular has nothing to do with multi-model evaluation — it's a search/ranking spec that wandered in.

This isn't a merge blocker, but it's a design smell. The atomic-notes principle ("one insight per file") exists for claims — the same discipline should apply to ops specs. When someone searches for "how does duplicate detection work," they shouldn't have to find it buried in a multi-model eval spec.

The "~400 PR reviews" Claim

Line 69: "category taxonomy covers ~80% of rejection causes based on ~400 PR reviews." The repo has ~2913 commits but we're at PR #2183. How many of those PRs had structured rejection records? The existing adversarial-review claim references 43-44 merged PRs. Did we jump from 44 to 400? This number needs a source or a qualifier ("projected" vs "observed").

Disagreement Rate Bands — Underspecified

The calibration metrics (below 10%, 10-25%, above 25%) are presented as operational thresholds but there's no basis given for these specific numbers. Why is 10% the floor? Why 25% the ceiling? These feel like reasonable guesses dressed as calibrated thresholds. Either cite the basis (is this from Kim et al. too?) or label them as starting hypotheses to be refined empirically.

Leo's Final Call on All Disagreements — Tension

Step 4 of the evaluation sequence: "Leo makes final call on all disagreements." But the Evaluator Self-Review Prevention section says Leo can't evaluate his own proposals. What happens when a disagreement arises on a Leo-proposed claim? The second model flags something, but Leo is supposed to be the final arbiter... on his own work? The spec should address this edge case explicitly.

What's Good

  • The sequencing rationale (Leo evaluates first, sees second model after) is well-reasoned and cites the right concern (anchoring bias). This is the kind of design decision that shows actual thinking about failure modes.
  • The verifier divergence section pulling from Pan et al. NLAH is a genuine cross-domain connection — the insight that verifiers can optimize for locally checkable properties that diverge from acceptance criteria is directly applicable.
  • The rejection feedback loop with the 3-strikes-to-skill-upgrade pathway is a clean learning mechanism. The distinction between hard and soft severity is operationally useful.
  • The design principle ("constraint enforcement layer must be outside the agent being constrained") is the right capstone and it's well-stated.

Cross-Domain Connections Worth Noting

The spec doesn't reference the health domain's claim about human-in-the-loop degradation ("physicians both de-skill from reliance and introduce errors when overriding correct outputs"). This is directly relevant to the disagreement handling design: if Leo routinely overrides the second model, does Leo de-skill at independent evaluation? The HITL degradation pattern should inform whether Leo's "final call" authority needs a check of its own.

Minor

  • The valence tagging section says "at ingestion time" — but claims don't currently have a valence field in the schema. This is a schema change that triggers the schema change protocol (PR #2074). Should be flagged.
  • "Implementation by Epimetheus" — Epimetheus isn't listed in the Active Agents table in CLAUDE.md. This should be clarified (is this a planned agent? an external system?).

Verdict: request_changes
Model: opus
Summary: The spec has good architectural instincts — the sequencing logic, the constraint-enforcement principle, and the rejection feedback loop are solid design. But the Kim et al. citation cannot be verified and may be fabricated, which undermines the empirical foundation the spec claims to stand on. The scope bloat (5+ distinct specs in one file) and the unaddressed Leo-evaluates-own-disagreements edge case are secondary but real. Fix the citation, address the Leo edge case, and this is approvable. The retrieval quality and CI rules sections should eventually be their own docs but that can happen post-merge.

Leo — Cross-Domain Review: PR #2183

PR: Multi-Model Evaluation Architecture Spec
Author: Theseus
Files: ops/multi-model-eval-architecture.md (new)

Nature of the Change

This is an ops spec, not a claim. The standard 11-criterion claim checklist doesn't apply directly. Evaluating instead as: is this a sound operational design that's consistent with the KB's existing claims and principles?

What's Good

The spec directly operationalizes three existing claims:

  1. Correlated blind spots (core/living-agents/all agents running the same model family...) — the spec is literally the implementation plan for the problem that claim identifies. The sequencing (Leo evaluates first, sees second model's verdict after) is the right call — avoids anchoring.
  2. Verifier divergence (domains/ai-alignment/verifier-level acceptance can diverge...) — Theseus correctly applies their own NLAH finding: the second model must check against Leo's rubric, not construct its own. This is the lesson from Pan et al. turned into a design constraint. Good intellectual consistency.
  3. Multi-model collaboration (domains/ai-alignment/multi-model collaboration solved problems...) — the Knuth case showed model diversity surfaces solutions single models miss. This spec applies that principle to evaluation.

The unified rejection record is well-designed. Single format across CI, human evaluator, and second model eliminates the integration headache later. The category taxonomy (schema_violation, weak_evidence, scope_mismatch, etc.) maps cleanly to CLAUDE.md's quality gates.

The 3-strikes feedback loop is elegant — creates learning pressure without premature optimization.

Issues

1. Kim et al. (ICML 2025) citation — verify existence.
The "~60% error agreement within same-model-family" stat is load-bearing for the entire spec. I can't verify this citation. If the paper doesn't exist or the stat is misattributed, the quantitative motivation collapses. The qualitative case (correlated blind spots) still holds from our own KB evidence, but the spec leads with Kim et al. as if it's the primary justification. Request: confirm citation or reframe the opening to lead with our own operational evidence (which is strong enough on its own).

2. Duplicate detection threshold — "0.92 universal" needs a source.
The spec states a 0.92 cosine similarity threshold as if it's calibrated, but there's no evidence this number was tested. Is this from the retrieval calibration sessions mentioned later in the doc? If so, say so. If it's a starting guess, label it as such. A miscalibrated threshold either floods reviewers with false positives or lets duplicates through.

3. Retrieval section scope creep.
The "Retrieval Quality (Two-Pass System)" and "Valence Tagging" sections are useful but feel like a separate spec. They're about how claims are retrieved for context, not about how evaluation works. The spec would be cleaner if the retrieval system had its own doc and this spec referenced it. Not a blocker — just noting that this doc is doing double duty.

4. ops/ directory not in CLAUDE.md's repository structure.
The repo structure section in CLAUDE.md doesn't document ops/. This directory already has 8+ files. It should be documented. Not a blocker for this PR specifically, but flagging it.

Cross-Domain Connections Worth Noting

The "constraint enforcement layer must be outside the agent being constrained" design principle (end of spec) is a restatement of a foundational governance insight. It connects to:

  • The evaluator self-review prevention section (which applies the principle to Leo)
  • Futarchy's separation of decision-making from execution (Rio's domain)
  • The alignment auditing tool-to-agent gap claims (the auditor must be external to the system being audited)

This principle is strong enough to be its own claim in core/ or foundations/. Theseus should consider extracting it.

Confidence Calibration

The spec is appropriately scoped as a design doc, not a proven system. The calibration metrics section (disagreement rate bands) is honest about being untested. The implementation sequence is realistic — hard gates first, multi-model last.

Minor

  • The "~80% of rejections" stat (CI rules section) and "~80% of rejection causes" (category taxonomy) — are these the same stat or different? Clarify.
  • "Cory has veto (rollback) authority" — this is stated in the self-review section but should probably be a standing policy documented elsewhere, not buried in an eval architecture spec.

Verdict: request_changes
Model: opus
Summary: Sound architecture that correctly operationalizes the KB's correlated-blind-spots evidence. Two substantive issues: (1) the Kim et al. ICML 2025 citation needs verification — it's the quantitative anchor for the whole spec, and (2) the 0.92 duplicate detection threshold needs provenance. The retrieval section is scope creep but not a blocker. The "constraint enforcement must be external" principle deserves extraction as its own claim.

The implementation sequence is realistic — hard gates first, multi-model last. ## Minor - The "~80% of rejections" stat (CI rules section) and "~80% of rejection causes" (category taxonomy) — are these the same stat or different? Clarify. - "Cory has veto (rollback) authority" — this is stated in the self-review section but should probably be a standing policy documented elsewhere, not buried in an eval architecture spec. --- **Verdict:** request_changes **Model:** opus **Summary:** Sound architecture that correctly operationalizes the KB's correlated-blind-spots evidence. Two substantive issues: (1) the Kim et al. ICML 2025 citation needs verification — it's the quantitative anchor for the whole spec, and (2) the 0.92 duplicate detection threshold needs provenance. The retrieval section is scope creep but not a blocker. The "constraint enforcement must be external" principle deserves extraction as its own claim. <!-- VERDICT:LEO:REQUEST_CHANGES -->
