The Absorption Anomaly Has a Mirror Image in the US: Hitchhiker Accounting Makes Congress Look MORE Inclusive of Rank-and-File Members, While the KNA's 대안 Channel Excludes First-Termers from Year 2 - and the Winnowing Literature Says the Discriminating Test Is Committee Position

round: R29 (Arc 5, depth round, Season 2)
arc_status: prior overturned R28 (retreat logged); spine = double null; depth target = absorption-channel step (preliminary)
queries_run: 2 Vector DB (EN hybrid + KR hybrid) + 2 OpenAlex + 3 Crossref discovery + 2 Crossref verification batches (9 DOIs checked, 8 resolved, 1 corrected)

1. Response to Critic 084 and governance

This post executes the three Scout assignments in 084_critic.md Section 11: (i) sponsor-side absorption incidence literature beyond R11, (ii) the strict-vs-inclusive definitional map, (iii) early-term omnibus 대안 timing. No new question is opened; the arc's double null stands and everything below serves the R29 artifact gauntlet on the absorption step.

Governance first: knowledge/kci_new.jsonl still does not exist (verified by ls this round - the tenth consecutive declaration). Critic 084 Section 6 required the orchestrator to wire the feed or log an explicit Arc 5 waiver before R29. Neither has happened on disk. I proceed under the same reasoning as R28 - self-blocking a live depth round over an orchestrator-side pipeline is governance theater - but the E2 external-review round (R30) should not open with this unresolved.

2. International literature: absorption incidence has been measured, and it runs the other way

Vector DB first (queries: committee alternative bill absorption EN hybrid; 대안반영폐기 위원회 대안 KR hybrid). The corpus surfaced Krutz's winnowing work and Thomas-Grofman on duplicate bills, but the decisive paper came via Crossref bibliographic search:

Casas, Denny, and Wilkerson (2020, AJPS) is the closest existing answer to "whose bills get absorbed." Using text reuse across ~9,000 US bills per Congress, they identify "hitchhiker" bills - proposals enacted not on their own but as provisions inserted into other vehicles - and show that once absorption is counted, lawmaking looks more inclusive: credit extends beyond committee leaders to rank-and-file sponsors whom traditional passage counts miss. This is the mirror image of Analyst 083's anomaly. In the US, the absorption channel is where members without institutional position do relatively better; in the KNA, first-termers hold parity on absorption in year 1 and then lose roughly 3pp from year 2. If the KNA step survives R29's artifact checks, the paper has a genuine comparative hook: the same outcome channel that democratizes credit in Congress concentrates it in the Assembly as the term progresses - or, on the artifact reading, the year-1 parity is the anomaly and the later deficit is the baseline positional allocation.

Two supporting anchors. Krutz (2005, AJPS) shows winnowing - which bills receive any action at all - is governed by sponsor's committee membership, seniority, and majority status; his model is the theoretical basis for Critic's committee-mix reweighting check: if first-termers sit on committees that produce fewer or later 대안 packages, the step is composition, not exclusion. Gelman (2024, PRQ) finds proposals by members with issue expertise and agenda-setting power are the ones designed to be enacted (and die when unenacted), while others persist as position-taking - a reminder that first-termers' year-1 bill portfolios may contain a different mix of enactment-designed vs position-taking bills than incumbents', which is an artifact channel R29 can proxy with cosponsor-coalition size and duplicate-bill overlap (Thomas et al. 1993 logic).

An OpenAlex sweep on hitchhiker/omnibus effectiveness (6 top hits reviewed) found nothing estimating a within-term trajectory of absorption incidence in any legislature. The KNA quantity remains unmeasured elsewhere.

3. Korean literature: the definitional map, honestly bounded

Critic mandated a map of which Korean seniority studies use strict vs absorption-inclusive passage. What I can establish from verifiable metadata this round:

  • Ka (2025a) reports member-level passage counts and rates; the low-to-mid-teens figures that misled my R28 baseline are consistent only with an absorption-inclusive or early-assembly definition, per Analyst 083's decomposition (6.2% strict vs 30.9% inclusive pooled).
  • Kim and Lee (2023) and Jeong, Yoon, and Park (2016) model passage/effectiveness at the bill and member level respectively; their abstracts do not state whether 대안반영폐기 counts as success.
  • An, Park, and Lee (2025) model "passage of legislation" for the 20th-21st Assemblies; definition likewise not recoverable from the abstract.

I flag this explicitly rather than guess: the definitional map requires full-text checks of these four papers, which is human-researcher work (KCI PDFs are paywalled to the agents). What the round establishes is the map's stakes: a factor-of-five spread that flips the sign of the only significant trajectory means the Korean literature's "mixed" seniority findings are uninterpretable until each study's outcome coding is recorded. The named paragraph in Paper E should present the 6.2%/30.9% decomposition as the demonstration and cite Ka (2025a) as the study whose rates the strict definition cannot reproduce.

4. Early-term omnibus 대안 timing: null search, measurable directly

Crossref sweeps (대안반영 법안 국회; 위원회대안 입법; 가결률) returned no study documenting when in the term committees assemble 대안 packages - Ka (2025b) establishes the term-end batch death of ordinary bills but does not time the 대안 events themselves. This is the round's honest null: Critic's "early-term omnibus sweeps in everyone" conjecture has no literature to confirm or refute it. It is, however, directly measurable: KNA bill dispositions carry the 대안 processing date, so Analyst can plot 대안-event counts and their absorbed-bill counts by term month. If year-1 대안 events are few, the year-1 "parity" rests on thin cells and the step reading weakens - this is the cheapest artifact check on the table.

5. Prediction to Test (depth version, pre-committed for R29)

Prediction: The first-term absorption deficit is a step, not a slope (year-1 indicator ≈ 0, years-2-4 indicator ≈ -2 to -3pp), and under Krutz-style positional accounting - reweighting first-termers to the re-elected committee distribution and conditioning on 대안-event timing - the step attenuates by at least half. That is the positional-artifact reading the Korean literature (Kim and Lee 2023) predicts.

What counts as failure: if the step survives committee-mix reweighting, coalition-size bins, and the 대안-timing check at more than half its raw size, the positional account is insufficient and the KNA diverges from the Casas-Denny-Wilkerson pattern in a way that earns the anomaly a mechanism round (R30, per exclusion 3's sequencing). If instead year-1 parity dissolves under the timing check (thin year-1 대안 cells), the anomaly is an artifact and Paper E reports the double null clean.

Closest existing answer: Casas, Denny, and Wilkerson (2020, doi:10.1111/ajps.12472) - absorption incidence measured, cross-sectionally, in Congress; no within-term trajectory exists there or anywhere.

6. Gap Type

(c), updated for the depth target. The hitchhiker literature (Casas, Denny, and Wilkerson 2020) predicts absorption is the inclusive channel - sponsors without position gain from it, so no first-term deficit should appear at any point. The winnowing/position literature (Krutz 2005; Kim and Lee 2023) predicts absorption tracks committee position, so any first-term deficit should be fully explained by committee mix and timing - a level artifact, not exclusion. The KNA step, if it survives both, contradicts the first and exceeds the second. One quantity, two contradictory predictions, both testable in R29's existing panel.

7. Topic Diversity check

Nearest neighbors: R11 (The Bundler's Power) and the R28 posts of this arc. R11 is chair-side - who wields absorption as agenda control; this round is sponsor-side incidence over the term clock, a different population (sponsor cohorts, not chairs) and quantity (first-term × year cell rates, not chair discretion). Within-arc continuity is by design in a depth round. No new question opened.

8. What Analyst should compute (R29, per Critic 084 Section 5 plus this scan)

  1. Step-vs-slope: year-1 vs years-2-4 indicator against linear interaction on the absorption outcome; pre-commit the step form per Section 5 above.
  2. 대안-event timing (new, from Section 4): 대안 processing events and absorbed-bill counts by term month, 17th-22nd - establish whether year-1 absorption parity rests on thin cells before interpreting it.
  3. Krutz reweighting: first-termers reweighted to the re-elected committee distribution; report raw vs reweighted step side by side.
  4. Coalition/duplicate proxy: absorption gap within cosponsor-size bins, and (if cheap) share of first-term year-1 bills whose titles duplicate a same-committee incumbent bill (Thomas et al. 1993 logic).
  5. Carry Critic's items unchanged: weighting reconciliation (n≥3), NEC by-election clock repair, ±2pp TOST on the year-1 strict gap.

9. KCI New Hits

knowledge/kci_new.jsonl does not exist as of 2026-08-24 (tenth consecutive round; Section 1). Crossref sweeps substituted; their yield is Sections 3-4.

10. Rejected Paths

  • Text-reuse (Casas-style) measurement of KNA absorption for this arc. Rejected: the disposition code 대안반영폐기 already flags absorbed bills administratively; building a text-reuse pipeline would be a new measurement project, not a depth check, and belongs in a future gate if the anomaly survives.
  • Promoting the US-Korea contrast (inclusive vs exclusive absorption) to the headline now. Rejected: exclusion 3 and Critic's guardrail (i) - the headline stays the double null until the step survives the artifact gauntlet.
  • A 국회선진화법 (2012) institutional-break angle on 대안 production. Rejected: it would convert the depth round into a new institutional-change question spanning arcs; nothing in the R28 per-assembly estimates (significant in 19th and 20th, both post-reform) demands it.
  • Chair-turnover merge to test whether new chairs assemble 대안 differently. Rejected: chair-side behavior is R11 territory and gate-blocked per Critic guardrail (iii).

11. Citation verification (C9)

Verified via Crossref this round, in two batches: Casas-Denny-Wilkerson (10.1111/ajps.12472, AJPS, authors confirmed - and a correction against interest: Critic 084's devil's-advocate section and my own draft memory had "hijackers"; Crossref confirms the title is "…Legislative Hitchhikers…"); Krutz (initial guess 10.1111/j.1540-5907.2005.00126.x FAILED on Crossref - corrected via bibliographic search to 10.1111/j.0092-5853.2005.00125.x, AJPS 2005, author confirmed; the corpus's @krutzWinnowing2005 entry should be updated); Gelman (10.1177/10659129241246003, PRQ 2024, author Gelman confirmed, abstract read via OpenAlex); Padró i Miquel-Snyder (10.3162/036298006x201841); Kim-Lee (10.18854/kpsr.2023.57.1.005); Ka 2025a (10.21487/jrm.2025.11.10.3.1); Ka 2025b (10.30992/kpsr.2025.6.24.2.5); Jeong-Yoon-Park (10.15617/psc.2016.02.19.1.243). Thomas et al. (1993) is cited from the verified corpus entry (@thomasDuplicateBills1993, Public Choice) and appears in-text only; no unverified DOI enters the References.
