Batch 3's reviewers against each other (3 Oct)

The 18 unit tier lists of reports/tiers/sources/2026-10-03-tier3-other-factions.csv, as panels. Numbers from node tools/scratch/batch3-reviewers.js (panels from node tools/scratch/batch3-panels.js, the duplicate check from node tools/scratch/batch3-tyr-dup.js); the ledger's from node tools/ledgerstep.js --base tools/ledger-benchmarks/2026-10-03-step6-baseline.json --lists tyr.astrategas,tyr.auspex,tyr.hivemind,tyr.second,tyr.maelstrom.

Letters on one ruler, S A B C D F (F below D). ρ is Spearman on the shared units' letters (ties at their average rank); pairwise is the share of the pairs both lists separate that they order the same way. A list's noise ceiling is its letters against the mean letter of the other lists, on the units it shares with at least one of them. "Spread" is the gap between the lists' own percentiles for a unit (0 to 100), so a list that grades harder overall doesn't read as disagreement.

Tyranids: four lists in the CSV, one of them new

The three 11th-edition lists are ones we hold; their panels are left unchanged. What the CSV settles and where it differs:

• Auspex Tactics. One letter differs: the Tyranid Prime with Lash Whip is C in our summary and Tier 1 (S) in the transcript, graded as a pair with Hormagaunts. The transcript also grades the Lictor S, the Broodlord and Genestealers A, Gargoyles and Termagants B, Barbgaunts, the Toxicrene and the Winged Tyranid Prime C. Our summary's Barbed Hierodule (unmatched, C) is not in the transcript. The CSV dates the video 12 Sep.
• HivemindHobbies. Every shared letter agrees, and the CSV settles the attribution question (T-580): this file is HivemindHobbies' list, posted 21 Jun (a launch-window list, before any balance update), not early July. The CSV adds Harpy, Hive Crone and Mucolid Spores, all D. The panel's stand-in BSData commit (80568cc, 2 Jul) is 11 days after the video; points moves between 21 Jun and 2 Jul are unchecked.
• Into the Hive Mind. The "second" file is this channel's list (its five tier names are the same), posted 27 Jul, just after the July dataslate, not early July. Eight shared letters differ (ours → CSV): Deathleaper B → A, Neurolictor B → S, Screamer-killer C → B, Hive Guard B → A, Hyperadapted Raveners B → A, Tyranid Prime with Lash Whip B → S, melee Warriors A → B, ranged Warriors B → C. Four of those eight (Neurolictor, Lash Whip Prime, Screamer-killer, Hyperadapted Raveners) are silent placements the transcriber read from a low-resolution thumbnail of the final board, so the CSV is not certain there either. It adds Old One Eye, Pyrovores and the Maleceptor A, the Trygon B, the Hierophant and Termagants C, the Harpy and Hive Crone D.
• Astrategas Wargames is new: a Spanish-language list from the end of 10th edition (21 Apr), used as fitting and flagged 10th like Maelstrom's under Jordan's Tyranid rule. 48 of the ledger's 52 units; the Sporocyst, Harridan and Hierophant were left off the board on purpose and The Red Terror isn't covered. Five letters were lost in the captions and read from context (their why says so). A comparator on the Tyranid ledger, key astrategas.

Every pair, our panels

ρ / pairwise (pairs) / n shared / same letter. AU Auspex (summary), HH HivemindHobbies, IH Into the Hive Mind, MG Maelstrom (10th), AW Astrategas (10th).

Noise ceilings (leave one out)

Maelstrom sits closest to everyone (0.72 to 0.84), Astrategas included: the two 10th-edition lists agree at 0.84, as well as any 11th-edition pair. Into the Hive Mind, the one made after the July dataslate, is the outlier (ceiling 0.69).

A check, not a panel change: with the CSV's transcriptions in place of our three summaries, the 11th-edition three agree more (AU–HH 0.83, AU–IH 0.81, HH–IH 0.77, each on all 52 units) and their ceilings rise (AU 0.87, HH 0.87, IH 0.78), while Astrategas's falls to 0.71 (0.64, 0.66 and 0.50 against the three; 0.84 against Maelstrom). Whether the fuller transcriptions should replace the summaries as comparators, as the Space Marines' full Auspex transcript did, is the supervisor's call.

The units they disagree on most

22 of the 52 units graded by two or more of the five sit two or more letters apart. The widest, by spread:

(The Lash Whip Prime is S in both the Auspex and the Into the Hive Mind transcriptions: two of its letters here are the summaries'.)

The ledger against each Tyranid list (step-6 baseline)

Mean over the five: ρ 0.564, pairwise 74.5%. Astrategas is the ledger's weakest Tyranid list by every yardstick. It is a comparator only: the yardstick's lists (ledgerstep.js's ARMIES) are unchanged.

World Eaters: three lists

RP The Red Path (29 Jun, three hosts, a first look), TS Tactical Sugar (20 Aug; role rows, not a strength scale, folded to letters in its panel's scale), EX Exalted40k (12 Sep; placed by popularity in 25 well-placed lists, then adjusted). Each grades the same 30 units, all matched (EX's one "Chaos Predator" entry is both Predators at its letter).

Ceilings: RP 0.77 (90%, n 30), TS 0.86 (95%), EX 0.72 (86%). Five units sit two letters apart: Eightbound (B, A, S), Lord Invocatus (C, B, A), the foot Daemon Prince (S, S, B), Chaos Spawn (A, B, C), the Bloodthirster (B, A, C).

Genestealer Cults: two lists

RY 40k Rey (11 Sep, S to D), CV Christian Von Carmian (27 Sep, A to D, no S by design). 23 shared units.

ρ 0.56, pairwise 85% (132 pairs), 8 at the same letter; with two lists each one's ceiling is that pair. Three units sit two letters apart, all graded for one detachment by RY and in almost every list by CV: the Abominant, the Biophagus and the Magus (RY C, CV A). CV has no S, so a letter gap of one between them is often no gap at all; the spread (54 for those three) is the fairer measure.

The other armies: coverage

Every list's names matched a stub of its army; no name is unmatched. "Own stubs" leaves out Legends and Crucible.

The Genestealer Cults' and World Eaters' coverage: RY 24 of 24 own (the Brood Brothers left out), CV 23 of 24 own plus the Tectonic Fragdrill (Legends; the Goliath Truck, settled by a chat vote, left out); each World Eaters list 30 of 30 own.
