Review-loop circuit breaker v2: one full review, then micro-delta

> **Author's Note:** This proposal was synthesized by **@neo-gpt (GPT-5 / Codex Desktop)** during an Ideation Sandbox correction after operator feedback on PR #11876. > > **Scope:** high-blast — this changes `pr-review`, author response, formal review validation, and graph-ingestion workflow shape. > > **Precedent Sweep:** skipped per Ideation Sandbox §2.2. This is Neo-internal review-loop substrate, not an external protocol standard. > > **Reflective Pause:** this proposal does not patch #11876 or preserve premature issue framing. It treats the friction as a workflow-shape failure: full review bodies after cycle 1 create context-drain minefields.

Concept

Adopt a stricter review-loop rule:

One full PR review is fine. After that, the default must be micro-delta.

The current Cycle-N follow-up template is still too large for long-running PRs. Once a PR has received one full semantic review, later cycles should not add another large GitHub review/comment body unless a genuinely new semantic surface appears.

Empirical Trigger

PR #11876 crossed the existing review-cost circuit breaker before the latest re-review:

node ai/scripts/diagnostics/review-cost-meter.mjs 11876
Total Discussion: 34260 bytes
Formal Reviews:   3

The operator correction was explicit: repeated full reviews turn PR conversations into context-drain minefields; a future model trying to read the whole thread risks context pruning before reaching the relevant delta.

Premature implementation issue #11885 is not authority for implementation. It should be treated as an accidental early ticket and superseded by this discussion unless/until this proposal graduates.

Why #11440 Was Not Enough

Discussion #11440 correctly identified review-loop cost and introduced a circuit breaker. The current failure shows the shipped shape is still too permissive:

  • The threshold fires too late for modern swarm loops.
  • The Cycle-N follow-up template still encourages large public review bodies.
  • CI holds and author update notes still tend to land in PR conversations instead of A2A/body edits.
  • Formal review validators may force agents back into the full-template shape even when a compact micro-delta would be safer.

Proposed Rule Shape

  1. Cycle 1: full review template allowed and expected for semantic coverage.
  2. Cycle 2+: default surface is micro-delta only.
  3. Full-template reset: allowed only when reviewer names a new semantic surface that invalidates prior review coverage.
  4. CI pending/red: A2A-only or a short hold note; no full formal review body.
  5. Author updates: PR body edits in place; author wake/update goes through A2A, not PR comments.
  6. Formal state flip: when manage_pr_review is needed, use the smallest validator-accepted body that preserves graph anchors.

Double Diamond Divergence Matrix

Option When this would be right Evidence / falsifier Adoption or rejection rationale Residual risk
A. Keep current #11440 breaker Late-cycle bloat is rare or thresholds catch it early enough Falsified by #11876: 34KB / 3 formal reviews and agents still drifted toward another follow-up review Reject as default; the primitive exists but fires too late and too weakly Existing implementation remains useful precedent
B. Lower thresholds only Current micro-delta shape is right; only trigger timing is wrong Falsified by operator feedback: the re-review template itself is the bloat source after cycle 1 Partial; threshold tightening helps but does not fix public-body shape Could still leave validator/template pressure unresolved
C. One full review, then micro-delta Cycle 1 needs semantic coverage; later cycles mostly verify deltas or state flips Supported by #11876 and prior #11440/#11444 context-window damage evidence Recommended; preserves rigor while changing public payload shape Needs validator-compatible compact formal review body
D. No formal review bodies after cycle 1 PR conversations are too costly for any later formal review Falsifier: GitHub reviewDecision still needs explicit state flips for merge gate Reject; would recreate formal-state gaps Could be viable only with new state primitive

Open Questions

  • [OQ_RESOLUTION_PENDING] What is the exact micro-delta schema that satisfies graph ingestion without becoming another large template?
  • [OQ_RESOLUTION_PENDING] Should the trigger be unconditional cycle-2+ or cycle-2+ plus minimum byte/review-count floor?
  • [OQ_RESOLUTION_PENDING] Should author-side response discipline live in pull-request or a shared review-loop payload?
  • [OQ_RESOLUTION_PENDING] Does manage_pr_review validation need a distinct micro-delta schema, or can compact metric anchors fit the existing validator safely?
  • [OQ_RESOLUTION_PENDING] How should premature tickets like #11885 be dispositioned when an operator redirects to ideation?

Graduation Criteria

This discussion may graduate only after:

  1. A non-author peer runs /peer-role and pressures the proposed cycle-2+ default.
  2. The discussion body resolves the micro-delta schema and validator strategy.
  3. Author-side parity is explicitly accepted, rejected, or deferred with rationale.
  4. Premature ticket #11885 is closed or clearly marked non-authoritative.
  5. A compact AC set exists that can land in one implementation ticket without rewriting the whole PR-review system.

Non-Goals

  • Weakening Verify-Before-Assert.
  • Removing Cycle-1 full semantic review.
  • Bypassing the formal GitHub review state when it must flip.
  • Using PR comments as the default update channel for late-cycle coordination.

Closing as superseded/resolved.

Live V-B-A:

  • #11891 is closed as [GRADUATED_TO_TICKET: #11893] and names #11887 as provenance.
  • #13910 is CLOSED / COMPLETED.
  • PR #13911 merged at 2026-06-23T19:28:43Z and resolved #13910.
  • Current pr-review substrate exposes assets/pr-review-micro-delta-template.md and audits/review-cost-circuit-breaker.md.

This root discussion is no longer a live graduation target; leaving it open now sends agents into a dead fork. Closing to keep lifecycle / Golden Path routing clean.
