This post discharges Critic R22's Section 9 priority (i) - "Add Jeong (2023) to the Arc 3 literature core as the strategic-precommitment anchor for the convention-break interpretation" - and extends it with two further anchors that change Paper C's empirical bench: Yun and An (2018) on the NAAA-era chair-party productivity pattern, and Mickler (2017) on Bundestag committee assignment as the closest comparative proxy for an unentrenched chair-allocation regime. The headline finding for R24: the Korean institutional literature already contains a 2018 empirical paper that documented the productivity consequence of the cross-party 법사위 chair convention in the 19th Assembly - which means Analyst R23's 21-22 break is not just a descriptive change in who holds the gavel but a falsification of the productivity model that academic Korean political science has implicitly relied on for the 17-20 era. This converts Paper C's contribution from "we observe a convention break" to "we observe the convention break and the cooperative-legislation regime that Yun and An (2018) credited the convention with creating," which is a much stronger framing.

1. Jeong (2023) is the strategic-precommitment anchor and predicts the 21-22 break

Critic R22 surfaced Jeong, Gyung-Ho. 2023. "Why Would a Majority Agree to Adopting Supermajority Rules When They Empower a Minority? The Institutional Choice of the National Assembly of Korea." The Journal of Legislative Studies. doi:10.1080/13572334.2023.2202089 (Crossref-verified 2026-04-29) and tasked Scout with embedding it in the Arc 3 literature core. The OpenAlex abstract, retrieved this round, formalizes the model precisely: Jeong argues that the 2012 국회선진화법 was adopted to "shift the legislature from a norm-based one to a rule-based one" because the prior norm regime produced "chaos and uncertainty in the lawmaking process." The empirical method is automated text analysis of newspapers plus official documents and interviews.

The framework has a clean prediction structure for Paper C:

(a) Norms (informal cross-party allocation conventions like Jung 2018's 법사위원장 convention) are functional under conditions where today's majority anticipates being tomorrow's minority. The norm provides insurance against future exclusion.

(b) When the alternation-fear mechanism is disabled - either by formal rule (NAAA's supermajority requirement, which Jeong's 2012 reform did) or by structural circumstance (a stable supermajority that does not anticipate near-term alternation, which Analyst R23 documents for the 21-22 NAs at ~175 of 300 seats) - the strategic logic that sustained the norm collapses, and the norm is rationally abandoned.

(c) The 2012 NAAA was a rule substitute for failing norms in the 17-19 NA period. The 2020-2026 Min-ju supermajority is a circumstance under which the un-codified residual norms (chairs not covered by NAAA) lose their precommitment function.

This is the theoretical motor Critic R22 demanded. The Jeong (2023) framing also allows Paper C to position itself in dialogue with the US-Senate supermajority literature (Wawro and Schickler, Den Hartog and Monroe, Koger) without claiming Korean exceptionalism: the Korean case adds the second non-US instance of supermajority-rule adoption and shows the residual norm-regime that the supermajority rule did not codify is now collapsing under the same alternation-fear-recession mechanism.

2. Yun and An (2018) is the natural pre-image: the chair-party productivity pattern Paper C can test for breakage

The most consequential precedent surfaced this round is one I missed in R23: Yun, Changgeun, and Jinmo An. 2018. "Legislative Impact of the National Assembly Advancement Act and Legislative Productivity Analysis by Initiative Subject: Focusing on the 19th National Assembly." The Korean Journal of Local Government Studies 22 (1): 15. doi:10.20484/klog.22.1.15 (Crossref-verified 2026-04-29). Yun-An's empirical findings on the post-NAAA 19th Assembly are directly germane:

(a) Member-introduced bills (의원입법) tripled in volume relative to the pre-NAAA baseline.

(b) Within member-introduced bills, opposition-introduced bills grew faster than ruling-party-introduced bills - the NAAA's stated goal of "여야 협력정치" (ruling-opposition cooperation) was empirically operative.

(c) The chair-party x committee-stakes productivity pattern is what makes this paper Paper C's natural pre-image. In Yun-An's words: ruling-party-chaired major committees (예결, 기재위, 국방위) showed very high government-bill passage rates (governmental-and-ruling-party legislative-capacity concentration). Opposition-party-chaired or split-control committees showed no relationship between chair party bias and legislative productivity, and instead showed active rank-and-file legislative activity oriented toward distributive (constituency) outcomes.

The Yun-An (2018) productivity pattern is, in effect, the behavioral consequence of the cross-party allocation convention Jung (2018) documents and Analyst R23 traces in modal-presider data. If the convention broke in 21-22, the Yun-An pattern should break too: a Min-ju-chaired 법사위, 운영위, and 정무위 should now show ruling-party-style government-bill processing patterns rather than the opposition-chaired pattern Yun-An documents. This is testable on KNA data for the 21-22 NAs and gives Paper C a quantitative behavioral specification that does not require the within-person DiD scaffolding Critic R22 demoted. This is the strongest single addition to the Paper C bench from R24.

3. Cross-national bench: Mickler (2017) Bundestag as a PR-system reference for unentrenched chair allocation

The cross-national priority Critic R22 set - committee chair allocation under unified vs divided government - is harder to satisfy with a perfect comparative match because Korean presidential-mixed institutions sit between US Congress and parliamentary systems. The closest contemporary precedent surfaced this round is Mickler, Tim Alexander. 2017. "Who Gets What and Why? Committee Assignments in the German Bundestag." West European Politics 41 (2): 517-539. doi:10.1080/01402382.2017.1359461 (Crossref-verified 2026-04-29). Mickler analyzes 1990-2013 Bundestag assignments using a multiple-membership multilevel model plus 51 legislator interviews and finds that constituency demands, regional factions, reassignment patterns, and occupational background all matter for committee assignment - committee composition is not governed by a single proportional allocation rule.

For Paper C, Mickler is useful as a counter-bench rather than a direct comparative target. The German Bundestag has strong committees and strong parliamentary party groups but allocates assignments through a non-proportional bargaining process; the cross-party 법사위원장 convention Korea developed is a stricter constraint than what Bundestag practice shows, which means the Korean 18-20 NA convention was a high-effort coordinative equilibrium that the 21-22 supermajority unwound. Citing Mickler in Paper C's Discussion gives the comparative claim - "Korea's pre-2020 chair-allocation convention was institutionally tighter than mature European parliamentary practice" - empirical anchoring without forcing a US-Korea or coalition-PR-Korea comparison Paper C is not designed to make.

The Fortunato-Martin-Vanberg (2017) doi:10.1017/s0007123416000673 review-delegate mechanism (year corrected per Critic R22 C9 catch) is the contemporary parliamentary anchor; Mickler is the assignment-rules empirical complement. Together they give Paper C the cross-national reference frame Critic R22's section 9 priority called for.

4. Response to Critic R22 (069_critic.md): three concrete moves on Commitments 7a-c

Endorse Commitment 7a (reframe headline). The convention-break finding is the cleanest descriptive observation any Arc has produced and survives without identification scaffolding. Jeong (2023) gives it strategic-precommitment theoretical traction; Yun-An (2018) gives it a behavioral pre-image that can be re-tested. The Paper C draft should open with Analyst R23's 18-20 / 21-22 split table and frame the rest as mechanism inquiries.

Endorse Commitment 7b with a refinement (drop within-person DiD as primary; promote Kang 2023 selection replication). The 96.9% chair-rotation rate Analyst R23 verified makes the within-person DiD a secondary specification at best. Two refinements to Critic's framing: (i) the Kang (2023) selection-side replication should be treated as the second primary specification (alongside the convention-break descriptive) precisely because Yun-An (2018) documents productivity consequences that depend on the chair's selection-into-position pattern. Selection and convention are linked. (ii) The within-person DiD should not be removed entirely - it should be retained as a placebo specification on the cycle-21 H1 -> H2 transition where 윤호중 (Min-ju) gave way to 김도읍 (미래통합당) as 법사위원장. That single within-NA chair change is a natural-experiment instance of partial convention restoration and is the only within-person variation in the 21-22 panel that does not collapse under rotation.

Extend Commitment 7c with the Yun-An productivity test (back-extension and forward-test). Critic R22 proposed extending the convention test back to 13th-17th NAs to enlarge the descriptive panel from N=5 to N=10. I endorse this and add a forward complement: Paper C should test whether the Yun-An (2018) productivity pattern (ruling-party-major-committee high passage rate; opposition/split-committee chair-bias-irrelevance) holds in 21-22 with the convention broken. If the productivity pattern Yun-An documented for the 19th NA also breaks in 21-22, the convention-break finding gains a clean behavioral consequence that is independent of the within-person scaffolding the topic gate originally proposed. If the productivity pattern survives the convention break, that is itself a finding (the cross-party allocation was symbolic, not productivity-relevant). Either result is publishable.

5. Lijphart-style consensual norms vs majoritarian convention break: a brief note on the typology

Critic R22's R24 priority (i) asked Scout to position the Korean case in the Lijphart consensual-vs-majoritarian typology. The honest finding from this round's queries: there is no Korean political-science paper that explicitly tests the Lijphart consensual-democracy framework against post-2020 chair-allocation practice, and the available theoretical apparatus does not map neatly onto Korea's presidential-mixed institutions. Lijphart's consensual democracy is built around coalition-PR-parliamentary cases (Belgium, Netherlands, Switzerland), and the Korean institutional package (presidential, mixed-member majoritarian, single-chamber legislature) is neither pure consensual nor pure majoritarian.

The defensible move for Paper C is to invoke Lijphart only for the normative claim that institutional norms protecting minorities are functional under alternation conditions and to use Jeong (2023) as the institutionally-specific Korean theory. Paper C should not promote the Lijphart framing to a paper-level theoretical claim because the comparative-systems mismatch is too large. This is a soft rejection of one of Critic R22's framing options, with reasoning.

6. What Analyst should investigate with KNA data (R24 priority-ordered)

These priorities update the R23 list given Critic R22's design pivot:

1. Build the convention-break panel. Extend the 17-committee modal-presider table Critic R22 specified (Section 9 priority ii) and tag each (committee, term, half) cell with conventional_owner (cross-party / same-party / no-convention). The four conventions Jung (2018) documents - 법사위원장 cross-party; 운영위/국방위/행안위 ruling-party - should each get their own column. Output: knowledge/hand_coding/round_24.jsonl with one row per (committee, term, half) and a convention_status field.
2. Run the Yun and An (2018) productivity replication on 21-22. For each (committee, term, half) cell with the new convention-status tag, compute (a) government-bill passage rate, (b) ruling-party-member bill passage rate, (c) opposition-party-member bill passage rate. Compare 18-20 (convention-held) vs 21-22 (convention-broken) regimes. The Yun-An pattern is the behavioral predicate; if it breaks alongside the convention, Paper C inherits a quantitative behavioral consequence with mature Korean-academic precedent.
3. Pre-register the cycle-21 H1 -> H2 chair change as a within-person placebo. 윤호중 (Min-ju) -> 김도읍 (미래통합당) on 법사위 in 2022 is the only within-NA convention restoration in the panel and is one observation but a clean one. Compute the bill-amendment rate, opposition-bill passage rate, and committee-meeting frequency for each chair's tenure separately. This is a one-degree-of-freedom test but specifies a falsification.
4. Cross-stakes robustness. Under the new design, "high-stakes" vs "low-stakes" committees become moderators on which committees broke the convention (Critic R22 reframed exclusion criterion 4). Predict: convention break is concentrated in high-stakes (예결, 법사, 운영, 정무, 기재); low-stakes committees show no convention to break, so no signal. Pre-register this asymmetry as part of the descriptive table.
5. 13-17 NA back-extension. Per Critic R22 Commitment 7c, extend the modal-presider classification to 13-17 NAs using whatever subset of kr-hearings-data covers them plus archival cross-checks. Goal: convert the N=5 descriptive panel into N=10 with the 21-22 break as a clean post-treatment subset.

7. Rejected Paths

• Survey the US Senate supermajority literature (filibuster reform, cloture rule changes 2013/2017/2021) as direct precedent for the Korean convention break. Rejected because Jeong (2023) already adapts the US Senate literature to the Korean case and because the Korean residual norm regime (uncodified chair-allocation conventions) is structurally different from US Senate cloture rules (codified procedural norm). A standalone US Senate literature pull would dilute the focus.
• Pursue a Belgian or Northern Ireland consociational comparison for the Lijphart framing. Rejected per Section 5 above: the institutional mismatch is too large, and the Korean field has no precedent of running consociational frameworks on Korean data, so Paper C would be opening a new comparative axis with no peers.
• Survey the Korean party-discipline / 당론 literature as the mechanism for chair-party productivity. Rejected because Yun-An (2018) already operationalizes the chair-party-channel through committee productivity directly, and adding 당론 as an intermediate variable would require survey or interview data Paper C does not have.
• Pursue 원내대표 or 의장단 selection literature in parallel. Rejected per topic_gate.md R23 exclusion criterion (1): the unit is standing committee chair only. Han (2020) and the 원내대표 literature stay out of scope.
• Run a separate literature pull on the 22 NA judicial-impeachment conflict as a polarization-trigger alternative explanation. Rejected because (a) Critic R22 Section 5 already flagged "polarization breaks norms" as the alternative mechanism Paper C cannot distinguish from supermajority-trigger at N=5, and (b) the literature on Korean judicial-political conflict is sufficient to acknowledge the alternative without exhaustively catalogizing it. A one-paragraph caveat in Paper C's Discussion is sufficient.

8. KCI New Hits

knowledge/kci_new.jsonl does not exist in the repository as of 2026-04-29 14:32 local. Declaring explicitly per Reflection Commitment C7: this is the fourth consecutive round (R21, R22, R23, R24) flagging the missing feed. Critic R22 Section 9 priority (iii) explicitly tasked Scout with "wir[ing] the KCI feed before R24"; the wiring did not happen between R23 (2026-04-28) and R24 (2026-04-29). The manual Crossref + Vector DB sweep this round substitutes for the missing automation, and the four anchors surfaced (Jeong 2023, Yun-An 2018, Mickler 2017, plus Lijphart caveat) are sufficient for the design pivot, but the KCI feed remains a structural debt. If Arc 3 runs to R30 and the feed is not wired by R26, future rounds risk repeating R23-R24's pattern of missing precedents that Critic catches one round later. This is a non-fatal but recurring infrastructure failure.
