Consolidated pool (role 1c) — LHC black-hole safety case
Merged overview step 2 starts from. Six 1b searchers minted 77 source nodes (74 live after de-duplication); a top-up round added 3 more (S-78–S-80) → 77 live. Grouped by leg of the safety case, best-first within group (searchers’ own orderings preserved).
Main question: “Was the risk that LHC collisions destroy the Earth (via stable micro black holes or other proposed mechanisms) truly put to rest, and what does that conclusion hinge on?”

Checked and NOT duplicates: the two Unruh 1976 papers are distinct — S-59 - Unruh 1976 — Notes on black-hole evaporation (PRD 14 870) vs S-57 - Unruh 1976 — Absorption cross section of small black holes (PRD 14 3251). S-74 - Koch, Stöcker, Bleicher 2005 — black-hole event-generator cross-sections (hep-ph/0507138, 2005) is a different paper from the Koch–Bleicher–Stöcker exclusion paper (S-10). The two Page 1976, two Bird et al., two Callan 1982, and two Giddings–Mangano nodes are each legitimately distinct works.

Audit against 1a’s search plan
Budget vs delivered (write, per slice): 1: 12→8; 2: 20→21; 3: 20→8; 4: 16→16 (14 live after 2 dups that re-minted slice-1 nodes); 5: 16→16; 6: 16→8. Totals 77 minted / 74 live vs 100 planned. The plan predicted the shortfall would land in slices 3 and 6, and it did — both were closed named lists, not open literatures to snowball, so under-budget ≠ under-covered for the argument spine.
Every side represented? Yes. Pro-safety: slices 1–5. Critics: slice 6 (Plaga, Rössler, litigation) + risk-methodology (Kent, Ord et al., Johnson, Posner, Calogero). Soft-spot dissent is deliberately not ghettoised — it also lives inside slice 2 (Helfer/Unruh/Jacobson/Belinski + remnant scenario) and slice 5 (vacuum-metastability). Both physics-dissent and methodology-dissent branches are populated.
Two independent empirical legs both solid? Split held — cosmic-ray data (slice 5, 14 nodes across fluorescence/ground-array/hybrid, 1963–2025) is robust and redundant. Compact-star data (slice 4) was 3 primaries with zero redundancy; the top-up added S-80 (Antoniadis 2013, a second independent ~2-M☉ pulsar), so the NS-mass point now has two independent measurements (Demorest + Antoniadis) alongside 1 WD-mass and 1 WD-age. Now adequate — the most load-bearing NS-density data point is no longer single-sourced; WD mass/age remain single-primary but were never the tightest constraint.
Known metadata gaps (report only, not fixed here): citation_count is unknown for the large majority of the pool (searchers hit Semantic Scholar / INSPIRE rate limits; slice 2 is the exception, INSPIRE counts present). S-2 and S-6 were characterized from WebSearch snippets, not direct CDS page fetches (bot-check) — exact institutional wording may need a re-open. S-7 (LA-602) PDF OCR’d badly; summary from secondary confirmation. S-25 (Rössler) has no primary text — node rests on a secondary commentary page.
Observation-selection / anthropic-shadow gap — RESOLVED by top-up. The pool now carries S-79 (Ćirković–Sandberg–Bostrom 2010 “Anthropic Shadow,” load-bearing — explicitly lists collider catastrophes as an example class) and S-78 (Bostrom & Tegmark 2005 selection-effect bound). Residual note: no standalone primary applies the selection-effect correction to collider safety specifically — S-79 is the closest and does so by example; step 3 should attribute that leg to S-79 rather than expect a dedicated paper. Giddings–Mangano themselves partly pre-empt the shadow by using the survival of other stars we did not need to observe (breaking the anthropic conditioning); with S-78/S-79 the pool now represents both the objection and that structural rebuttal.
Verdict: both previously-thin axes are now adequate. Pool = 77 live (74 + S-78/S-79/S-80). No further top-up recommended.
