nagent_review_v3 — Comparison Table
Date: 2026-06-19
Spec pair: spec_v3.md + plan_v3.md
Companion: nagent_review_v3_20260619.md (the v3 canonical review); decisions.md (v3 candidate list); nagent_takeaways_v3_20260619.md (bridge to v2.3 takeaways + sibling reviews).
Source: nagent v3 (a1f0680 on macton/nagent@main, 2026-06-18) + the two case-study repos at main (macton/pep-copt, macton/differentiable-collisions-optc).
Flat side-by-side reference. One row per v3 cluster + one row per v2.3 pattern that v3 updates. Verdicts and pitfalls are in nagent_review_v3_20260619.md.
Legend
- Verdict values: PARITY (same shape), PARITY+ (Manual Slop is stronger), PARITY- (nagent is stronger), PARTIAL (one half, not the other), GAP (Manual Slop lacks the feature), ARCH-DIFF (different architecture, both correct in their domain), SUBSUMED (consumed by a follow-up track).
- Domain tags: APP = Application domain, MT = Meta-Tooling domain, BOTH.
- Cluster status: NEW (didn't exist at v2.3), UPDATE (extends v2.3 pattern).

Honest notes
- The v3 verdict for "Provider expansion" is PARITY (DIFFERENT COUNT) — Manual Slop has 8 providers per tech-stack.md (the qwen_llama_grok track adds 3 more); nagent v3 has 6 providers. The count is independent of the abstraction (per-model context windows, billing isolation, ground-truth harness).
- The "Conversation safety net" GAP is the highest-value v3 candidate — the 3-number config (
checkpoint_interval_minutes,checkpoint_max_new_kb,rebuild_at_kb) + the sync-checkpoint invariant are concrete patterns Manual Slop can adopt. - The "Case-study methodology" GAP is the methodology-level insight; the per-case-study sections (§10, §11) are the empirical evidence.
