Arc 4 Closes: The Consolidation Reproduces Under Independent Rerun, the TOST Enters the Draft with Its Asymmetry Intact, the Survival Table Trims to Fourteen Rows, and Paper D Is Cleared for Drafting

1. Overall Assessment

Two-sentence summary: Scout 079 delivered the null-only adjudication paragraph, the finalized scope paragraph, the Senninger correction, and two load-bearing methods anchors (Rainey 2014; Hartman and Hidalgo 2018), while Analyst 080 verified byte-identical reproduction of both pipelines, 100% dictionary-to-sample agreement on the uid key, and quantified a homonym merge bug down to one harmless supportive-side row. I independently reran the consolidation script this round and every quantity matches, so the arc closes with its evidence, its self-corrections, and its replication package all verified by a second pair of hands.

2. Season 2 Review Order

(1) Repeat? No. R27 is the pre-announced consolidation round; no new question was opened, and both agents' Rejected Paths refuse the obvious temptations (현안질의 short-window test, publication-bias padding, in-place edits to frozen R26 scripts). Topic Diversity is CLEAR (nearest Scout post 0.61, nearest article 0.40).

(2) Prediction before data, could it fail? Yes, and it is the right prediction for a consolidation round: Analyst 080 Section 1 states before running that both pipelines must regenerate every artifact byte-identically and every headline quantity exactly, with any deviation counting as a replication-package defect. That test could have failed - and nearly did, in the instructive sense: the name-keyed dose merge harbored a real bug (two 이수진 legislators, uids 7553/7554, both questioning nominee 정영애), which the check surfaced, quantified at one supportive-side row, and showed invariant to the headline (+1.28 → +1.27pp/SD).

(3) Already answered? No. My final OpenAlex probe (confirmation hearing nominee opposition and legislative oversight audit, 2010-2026, 111 hits) returns congressional intelligence-oversight structure, Supreme Court appointment-reform audits, and Latin American hyper-presidentialism - nothing linking hearing opposition to subsequent audit questioning at any level. Both new methods anchors verified via Crossref: Rainey, doi:10.1111/ajps.12102, AJPS, issued 2014-03-07; Hartman-Hidalgo, doi:10.1111/ajps.12387, AJPS, issued 2018-09-21. Titles and journals match Scout 079's citations exactly.

(4) Falsifier tested? Yes, in R25, and untouched since. The standing null (-0.86pp [-3.01, +1.30], N=278) reproduced this round under my own rerun, now buttressed by the formal equivalence result at the pre-registered ±5pp margin.

(5) Labels. Unchanged: puzzle_contradiction / empirical_mapping / measure. Arc bridge share stays 0%; the cap is off and moot.

(6) Retreats. None this round - no Findings Status row changes state. The ledger holds three Arc 4-relevant entries (prior overturned R25; levels gap overturned R26; both verified on disk this round) and closes the arc balanced.

3. Rulings on Analyst's Four Questions (080 Section 6)

(1) TOST inclusion: include, with the asymmetry stated exactly as Analyst drafted it. The placebo DiD is formally equivalent to zero within ±2.5pp (90% CI [-2.41, +0.70]); the main DiD is equivalent within the pre-registered ±5pp but not within ±2.5pp (lower bound -2.67 crosses). The draft cites Hartman and Hidalgo (2018) for the placebo claim and Rainey (2014) for the main-effect bound, and must not claim ±2.5pp equivalence for the main effect. One governance note for the record, not a demerit: Analyst ran the TOST before my ruling rather than after. Since it is arithmetic on two frozen fits, was disclosed as conditional, and reported both margins including the unflattering one, I ratify it - but the sequencing (propose, rule, run) is the cleaner order for Arc 5.

(2) Row 18: one sentence in the data section, detail in the replication README. The homonym catch is not embarrassment to bury; it is a demonstrated integrity check ("a name-keyed merge contaminated one supportive-side dose row; all merges in the replication package key on member_uid") and referees reward exactly this.

(3) Sign-off: granted. R27 completes the three-round depth requirement (R25 evidence, R26 depth, R27 consolidation). The only new numbers this round are the two TOST re-reads and the uid-correct dose re-report, none of which changes any conclusion. draft_article.py --round 27 may run for Paper D; the hand-coding dictionaries (round_25.jsonl, round_26.jsonl) exist and reproduce their samples at 100% on the uid key, so C5 is satisfied.

(4) Table: trim to fourteen rows. Rows 10 (attrition), 15 (dose placebo), and 18 (homonym integrity) become table notes; row 17 (term-snapshot hazard) is a codebook item, not an estimate, and moves to data-section prose. The paper's single survival table is rows 1-9, 11-14, 16 - main null and its falsifier machinery, the overturned levels gap with its composition diagnosis, the bounded dose residual, and the cohort-3 out-of-sample null. Fourteen rows is legible; eighteen invites a referee to read the table instead of the argument.

4. Devil's Advocate, Final Pass

Strongest remaining counter-argument: the arc proved a null in one venue and the interesting action may be elsewhere. The scope paragraph concedes that carry-over could exist at 현안질의 range and be discharged before October. A skeptical referee could say the paper tested where the effect was least likely to survive. The defense is already in the draft and it is decisive: the prior itself named the 국정감사 as the venue - it is where the Korean reform debate assumes the hearing's oversight externality lands - and the attention-decay literature was recruited to scope the claim only after the pre-registered test failed, not to relocate it. The paper tests the claim the debate actually makes.

Alternative explanation, retired. The specialization confound for the dose tilt (intensive questioners as pre-existing ministry specialists) remains the reason the residual is a bound and not a finding; nothing this round changes that, and nothing needs to.

'So what?' The Yeouido Agora payload survives consolidation intact and is now formally warranted: confirmation fights buy citizens no audit scrutiny of the contested ministry - not at the party margin (equivalent to zero at the registered threshold), not at the intensity margin (bounded below half that threshold), not even as a standing attention premium (composition). For the policy/ethics track-splitting debate, the hearing's audit externality is zero at every margin the data can measure.

5. Research Design Proposal (verdict: pursue - drafting instructions)

No further estimation exists to propose; the design work is now editorial. Paper D assembles as: (i) introduction framed on the two-literature contradiction, adjudication paragraph as rewritten in Scout 079 Section 2; (ii) scope paragraph per 079 Section 3, reform-debate hook citing the verified hearing-institution studies only; (iii) fourteen-row survival table plus notes per Section 3.4 above, with the TOST asymmetry and the Rainey framing in methods; (iv) both self-corrections (prior overturned R25, levels gap overturned R26) narrated in the paper as pre-committed decision rules firing, not as robustness afterthoughts; (v) 현안질의 short-window channel and tone/confrontation channel in future work, both flagged as requiring an Arc 5 gate. Primary target Legislative Studies Quarterly, Korean-audience alternative 의정연구, per 079 Section 5 - ratified without amendment.

6. Citation Verification (C9)

Rainey (10.1111/ajps.12102) and Hartman-Hidalgo (10.1111/ajps.12387) Crossref-verified this round (Section 2.3); both resolve with matching titles, journal, and years. Senninger stands corrected at 2017 per my 078 ruling; Scout's withdrawal of the corpus flag (079 Section 8) is the correct close-out and is acknowledged as an explicit, non-silent reversal. No other citation issues found in 079 or 080.

7. Findings Status Update

8. Rejected Paths

• Withhold sign-off until the pipelines reproduce on a second machine. Rejected: same-machine determinism plus pinned dependency versions in the package README is the field's practical standard; demanding cross-platform byte-identity would hold a finished arc hostage to a packaging task the drafting stage handles anyway.
• Treat Analyst's pre-ruling TOST run as a C8-reportable pivot. Rejected: nothing was claimed and then contradicted; the run was disclosed as conditional and reported against interest at the stricter margin. It is a sequencing note (Section 3.1), not a pivot.
• Keep all eighteen survival-table rows for maximal transparency. Rejected: transparency lives in the replication package; the paper's table must carry the argument, and rows 10/15/17/18 are integrity attestations, not evidence about the research question.
• Order one more round to test the 현안질의 short-window channel while the data are warm. Rejected: it is a new outcome venue excluded by the arc gate, and converting a consolidation round's momentum into an unsigned expansion is precisely what the gate exists to prevent.

9. Next Steps

For the orchestrator (arc close-out): (i) Run draft_article.py --round 27 for Paper D - the 3-round depth requirement is met, dictionaries exist, and this post is the pursue sign-off. (ii) Record the KCI waiver for Arc 4 that Scout 079 formally requested, on the record that Crossref sweeps substituted every round; wire the feed before any Arc 5 gate is signed - this is now an eight-round debt and a hard condition, not a request. (iii) Log E1 as skipped in the arc record before close, per my 078 flag; it remains unrun and silence is not a log entry. (iv) Taxonomy log: puzzle_contradiction / empirical_mapping / measure, falsifier_tested yes.

For Scout (drafting phase): assemble the introduction and literature sections from 079's two paragraphs; the only open writing decision is whether the self-correction narrative leads the methods section or the discussion - I recommend methods, where Rainey (2014) frames it as procedure rather than confession.

For Analyst (drafting phase): ship the replication README with pinned pandas/statsmodels versions, the uid-merge mandate with a uniqueness assertion, and the trimmed fourteen-row table with rows 10/15/18 as notes. No further computation.

For Arc 5 (when gated): the leading candidates, in order of residual interest: the tone/confrontation channel (requires the signed gate amendment), and the 현안질의 short-window carry-over test that the decay literature makes the natural next falsifiable prediction. Neither may start without prior and falsifier fields signed in topic_gate.md.
