Arsenal 1945 — Omega War
Stage 2 artifact review · staged research cycle: arsenal-1945 (game-fantasy follow-up) · research executed and page updated 2026-06-10
Research is complete; the full working packet (
research/_working/preliminary-arsenal-1945-research.md) is rendered below.
Approving this page (final compiled YAML) triggers Stage 3: write canonical research/arsenal-1945.md, archive the packet,
confirm this page, flip the index entry — then the historical-divisions cycle per the approved route.
docs/history/archive/2026-06-10/193246/alignment/):
the approved scope/source/assumption sections are condensed into the approval record below; all findings (ARQ1–ARQ6 + ARQ4b),
the per-faction arsenal tables, the phase-escalation mapping, assumption-register status, evidence matrix, coverage gaps,
glossary candidates, and new artifact-approval gates are new. Scope was executed as approved, with one addendum:
the scope-gate note about US Pacific rotation was folded in as ARQ4b (researched in §6); its war-morale /
sue-for-peace idea is recorded as a downstream campaign-design implication, not equipment research. The main-session sweep
method (noted on the Stage 1 page) was used as planned.
1. Stage 1 Approval Record approved 2026-06-10
- Scope/non-goals: approve-as-proposed (ARQ1–ARQ6; deliverable shape: per-faction equipment tables (category × era-band × plausibility tier), service/production evidence with citations, phase-escalation mapping, gaps register; non-goals: no stats/balance, no schema authoring, no division-roster authoring, no art sourcing, no genre mapping, no re-collection of approved evidence). Scope note (verbatim): "A note would be to consider which American units/equipment would be rotated to the Pacific even in the event of a Soviet conflict. This could be part of the conflict on the Allied side which is the overall war morale might cause the US to sue for peace or withdraw units for the Pacific. I suppose we can also do some research on this point which may impact our prior research?" — folded in as ARQ4b (US Pacific rotation), researched in §6. The war-morale / sue-for-peace mechanic is recorded as a downstream campaign-design implication. Impact on prior research: none contradictory — the approved premise narration already anchors the US drawdown ("the greatest army America ever raised begins to leave Europe"); ARQ4b deepens it with the documented redeployment machinery.
- Evidence coverage: approve-all-four (E1 encyclopedic references, E2 development/prototype histories, E3 orders of battle & theater presence, E4 genre precedent as calibration only).
- Coverage checkpoint: exhaustive sweep (loop until new angles stop producing novel evidence, as in the audience and fantasy cycles).
- Assumptions: accept-all (AR-A1 window ~mid-1946; AR-A2 ground first / air roster / naval light; AR-A3 Central Germany factions at full depth; AR-A4 paper projects tier-flagged; AR-A5 feeds-not-authors).
- Artifact destination: working packet at
research/_working/preliminary-arsenal-1945-research.md— written. - Proposed file changes: approve-file-set (Stage 3 may write
research/arsenal-1945.md, updatealignment/index.html, archive packet, convert this page to confirmed, append approved glossary terms, touchtasks/*.mdonly if real follow-up work emerges). - Post-approval route: continue-divisions-cycle — the historical-divisions cycle
(deck-buildable divisions + per-division unit composition, own staged mini-cycle) runs after this artifact is confirmed;
/game-genre-mapfollows.
Method note (carried): research subagents have no web access in this environment; the exhaustive sweep executed in the main session (10 search batches, ~39 queries, + 1 verification fetch, 2026-06-10). Stopping rule honored: the final batch produced only number-verification on already-captured items — no novel equipment classes or angles.
2. Executive Summary
- The "shelf of 1945" is real, dense, and two-sided. Western bloc: 6 Centurion prototypes in Germany from May 1945; 310 Pershings shipped to Europe before VE Day (200 issued, 110 with five armored divisions) plus one Super Pershing; Comet from December 1944; 1,163 Chaffees by May. Soviet bloc: 29 IS-3 built by 24 May 1945 (zero combat; 52 paraded through Berlin 7 Sept 1945); T-44s built through 1945 with zero combat and chronic readiness problems. Jets: Meteor IIIs flying ground-attack over Germany from April 1945; four YP-80As in Europe; captured Me 262 stocks on both sides. Every marquee almost-weapon of the premise narration is evidence-backed.
- The prototype shelf tiers cleanly under the ~mid-1946 window (AR-A1 held). In-production: Centurion Mk 1/2 (800 ordered Nov 1945). Production-ready: T-54 (prototype Feb 1945, accepted April 1946), IS-4, Vampire, Lincoln (operational Aug 1945). Prototype-in-window: T29/T30/T32, MiG-9 and Yak-15 (both first flew 24 April 1946), Hornet. Paper/stretch: T28, Tortoise, IS-6/IS-7, ARL 44 (hulls 1946, turrets 1949), La-9 (edge). The window discriminates instead of admitting everything — it works as a design rule.
- The old guard is enormous and load-bearing. 75 mm Shermans were still ~75% of US Shermans in Europe in January 1945; SU-76M production ran to October 1945; T-34-76s, KV remnants, and lend-lease-Sherman-standardized guards corps were in the field; Churchill VIIs and Cromwells stood beside Comets. Old kit is the early-phase deck spine for every faction, not filler.
- The faction map has real texture. Unthinkable itself planned up to 10 German divisions remobilised from POW status — and knew they could not be re-equipped by 1 July 1945 (the re-arm lag is historical, a natural mid-phase ramp). Rear-area German capacity is evidenced by three proxies: the British-run Laatzen line (9 Panthers + 12 Jagdpanthers to spring 1946), the postwar Czech Hetzer line (ST-I; 158 new G-13s for Switzerland from 1946), and Panzer-Brigade Norwegen's intact surrender (~60 Pz III + 10 StuG III). Satellites are wildly uneven: the Polish People's Army has real armored mass; Romania is army-scale infantry stripped of armor by the Soviets; Bulgaria runs on German-origin kit plus Soviet-delivered trophies; Hungary's two-division armistice army verifies the §1.4 extrapolation-not-fact ruling.
- ARQ4b — the Pacific rotation is documented roster pressure, not lore. ~1M soldiers earmarked Category II for the Pacific including 13 infantry + 2 armored divisions (400k direct Sept 1945–Jan 1946; 400k more by April 1946); First Army HQ Downfall-bound; Eighth Air Force HQ on Okinawa from 16 July 1945 converting to B-29s (a bomber never based in Europe). The US roster in a 1945–46 European war is a force being actively drained eastward — phase/event design material that deepens (and does not contradict) the approved premise narration.
- The phase ladder falls out of the tiers: early = standing Aug-45 kit with shelf items as rare spice; mid = in-production ramps + German re-equipment + rotation pressure; late = the production-ready/prototype reward shelf. SD2's A/B/C phase + activation-point precedent (verified) is the calibration.
3. ARQ1 — The Shelf of 1945 (late-war, barely fought)
All URLs accessed 2026-06-10. Confidence tags: high medium low. carried = reused from approved artifacts, not re-collected.
| Item | Where it physically stood / service window (evidence) | Conf. |
|---|---|---|
| Centurion Mk I (UK) | Six A41 prototypes with 5th Royal Inniskilling Dragoon Guards, 22nd Armoured Brigade, at Gribbohm, Germany, May 1945 — Operation Sentry troop trials, "the war ended too quickly" (Tank Encyclopedia, Wikipedia) | high carried + expanded |
| M26 Pershing / T26E4 (US) | Zebra Mission: first 20 T26E3 Jan 1945 (3rd/9th AD), first action 25 Feb near the Roer; 310 shipped before VE Day, 200 issued, 110 with 2nd/3rd/5th/9th/11th AD; one T26E4 Super Pershing up-armored in theater, "a small number of engagements" (Wikipedia, Army Historical Foundation, Tank Encyclopedia) | high carried + expanded |
| Comet (A34) (UK) | 29th Armoured Bde (11th Armoured Div) deliveries from Dec 1944; quantity issue after the Rhine crossing Mar 1945; Berlin parade July 1945 (Wikipedia) | high |
| M24 Chaffee (US) | 128 in ETO early Feb 1945 → 1,163 by early May; 4,731 built when production stopped Aug 1945; last four arriving armored divisions came Chaffee-equipped (Wikipedia, Mike's Research) | high |
| IS-3 (USSR) | 29 built by 24 May 1945 (17 passed testing); first three sent toward Germany with an independent Guards battalion — peace arrived first; first public display: 52 IS-3s, Berlin Victory Parade, 7 Sept 1945 (2nd Guards Tank Army), which "astonished the Western allies" (Wikipedia, Wikipedia, tank-afv) | high |
| T-44 (USSR) | 25 built by end-1944, ~190 by VE Day, ~965 across 1945 (sources split on completion timing — gap §12); zero combat: no spares, untrained crews, no specialist engineers (Wikipedia, Tank Archives) | high (no-combat) / medium (counts) |
| Gloster Meteor III (UK) | Four to Melsbroek, Belgium, 20 Jan 1945 (616 Sqn, 2 TAF); Gilze-Rijen Mar, Nijmegen Apr; ground-attack over Germany from April 1945 (Wikipedia, historyofwar) | high |
| YP-80A (US) | Four pre-production in Europe: two at RAF Burtonwood from 30 Dec 1944; two at Lesina, Italy (94th FS, 1st FG) — two recon sorties Mar 1945, no contact (Wikipedia) | high |
| Me 262 stocks (both blocs) | Watson's Whizzers collected nine flyable at Lechfeld May–June 1945 (Operation Lusty); Soviet NII VVS flew its first from Mar 1945 and seriously debated series-copying it (Wikipedia, key.aero) | high |
Inference: the premise's reward shelf has a front rank that is already in theater — Centurion, Pershing, IS-3, and Meteor are positioning facts, not counterfactuals. An August 1945 war opens with these in the order of battle at prototype/battalion scale — exactly the phase-gated payoff material Pillar 2 ("the 1946 arsenal gets its war") wants.
Gate — Shelf-of-1945 Verdict required
Accept the ARQ1 findings (the in-theater shelf list, numbers, and the "front rank already in theater" reading) as the canonical basis for the arsenal artifact?
4. ARQ2 — Plausible Prototypes (tiered, window ≤ ~mid-1946)
Tier vocabulary (glossary candidate, §14): in-theater / in-production / production-ready / prototype-in-window / paper. Window per AR-A1: in service, in production, or production-ready by ~mid-1946.
| Item | Development evidence (accessed 2026-06-10) | Tier in window |
|---|---|---|
| T29 / T30 / T32 / T28 (US heavies) | T29 (105 mm): 1,152 approved 12 Apr 1945, order cancelled Aug 1945, one built + ten retained for testing; T32: four pilots approved Mar 1945, built 1946; T30 (155 mm): prototype date conflicting (one capture Mar 1945; commonly 1947–48 — gap §12); T28 (95-t): two prototypes, "the war was over" (Wikipedia T29, T32, T30, T28) high (T30 date med) | T29 production-ready (cancelled); T32/T30 prototype-in-window; T28 paper |
| Centurion Mk 1/2 (UK) | Full production began Nov 1945 — 800 ordered (Leyland, ROF Leeds/Woolwich, Vickers Elswick); handful of Mk Is before the up-armoured Mk II took the lines; historical first unit deliveries Dec 1946 — a mobilized mid-1946 ramp is credible [acceleration inference flagged] (Wikipedia) high | in-production |
| Black Prince / Tortoise (UK) | Black Prince: six prototypes delivered May 1945; 300-vehicle contract cancelled 30 May 1945 in Centurion's favour; Tortoise A39 prototypes completed postwar (Wikipedia, Tank Archives) high | Black Prince prototype (cancelled); Tortoise paper |
| T-54 (USSR) | Design Dec 1944; prototype Feb 1945; trials Mar–Apr 1945; commissioned Apr 1946; production 1947 (Wikipedia, Tank Archives) high | production-ready |
| IS-4 / IS-6 / IS-7 (USSR) | IS-4: revived 1946, production late 1946, service 1947; IS-6 (Obj 252): cancelled after autumn-1944 trials; IS-7 lineage (Obj 257): early-1945 design studies (Tank Encyclopedia) high | IS-4 production-ready (late); IS-6 paper (cancelled); IS-7 paper |
| Vampire / Hornet (UK air) | Vampire entered RAF squadron service 1946; Hornet first flew 28 July 1944, squadron service mid-1946 (Wikipedia, Wikipedia) high | both production-ready |
| MiG-9 / Yak-15 / La-9 (USSR air) | MiG-9 and Yak-15 both first flew 24 April 1946; La-9 (piston) production Aug 1946 (Wikipedia, RuAviation, Wikipedia) high | MiG-9/Yak-15 prototype-in-window (window edge); La-9 edge |
| Avro Lincoln / B-29 (bombers) | Lincoln "attained operational status in August 1945" (Tiger Force) — in service on day one, unblooded; B-29 confined to the Pacific by a Dec 1943 decision; the only B-29 in England (YB-29 "Hobo Queen", 1944) was deliberate disinformation (Wikipedia, Wikipedia) high | Lincoln in-theater (in service); B-29 strategic-reallocation question → ARQ4b |
| ARL 44 (France) | Occupation-era clandestine component design; Feb 1945 respec (120 mm/48 t); hulls built 1946 (40 FAMH + 20 Renault), turrets not mated until 1949; 60 completed (Wikipedia) high | paper-in-window (national-pride flag item — weakest plausibility claim in the set) |
Inference: the AR-A1 window discriminates usefully — it admits Centurion/T-54/Vampire/Lincoln-class items as credible escalation, pushes MiG-9/Yak-15/T29-class items to a clearly-labeled top shelf, and flags ARL 44/La-9 as boundary stretch. The five-step tier vocabulary carried the whole sweep without strain — proposed for the glossary (§14).
Gate — Prototype Tiers Verdict required
Accept the tiered prototype shelf (items, tier assignments, and the flagged stretch items ARL 44 / La-9 / Tortoise) as the canonical basis? Note any tier you would move, add, or drop.
5. ARQ3 — The Old Guard (pre-war & early-war kit that still serves)
- US — the 75 mm Sherman is still the majority tank. 76 mm Shermans were only ~25% of Shermans in Europe by January 1945; M18 Hellcat 540 in ETO (Mar 1945); M36 ~236 in combat by 20 Dec 1944; M10 aging (production ended Dec 1943); M5 Stuart in wide second-line/recon use; M3 halftracks ubiquitous medium — general reference (Wikipedia M4, M18, M36, M10) high
- UK — Churchill VII and Cromwell still in the line beside Comet; Challenger/Firefly carry the 17-pdr; Valentine relegated to lend-lease/special roles; the gun park is 6-pdr/17-pdr/25-pdr (Wikipedia Churchill, Cromwell) high (types) / medium (exact Aug-45 unit states)
- USSR — T-34-76 second line, KV remnants, SU-76M mass, Sherman-standardized guards. 22,609 T-34-85s (1944–45) took the front line while T-34-76s persisted; ~30 KV-1s fought at Danzig (Mar 1945) and KVs appeared in Manchuria (Aug 1945); SU-76M = second-most-produced Soviet AFV (production to Oct 1945); lend-lease M4A2(76)s standardized the 1st & 3rd Guards Mechanized Corps, 9th GMC, elements of 6th Guards Tank Army; lend-lease share ~16% of the tank park (Wikipedia T-34, SU-76, Lend-Lease Shermans, KV) high
- France — the 1ère Armée is a US-equipped force and that is its identity. 1re/2e/5e Divisions Blindées on the M4 family (656 allocated via North Africa + ~100 more Nov 1944–May 1945), M10s from fall 1944 (French Shermans, tank-afv) high
- Germany — thin at the front, real in the rear. The fighting front was bled dry (15 Mar 1945: 117 Panthers in the whole West, 49 operational; ~193 operational AFVs total). But: the British REME assembled 9 Panthers + 12 Jagdpanthers from MNH parts at Laatzen, completed by spring 1946; the Czech Hetzer line ran postwar (ST-I for the Czechoslovak army; 158 new-built G-13s for Switzerland from 1946, Škoda); Panzer-Brigade Norwegen surrendered intact ~14 May 1945 at Trandum — ~60 Pz III + 10 StuG III plus PaK 40 stocks, reused by postwar Norway into the 1950s (vffwts.de MNH, Wikipedia Hetzer, Tank Encyclopedia Norway, Wikipedia Panther) high (captures) — synthesis is inference
Inference: the old guard is the early-phase deck spine for every faction, and the German rear-area capacity (works lines + intact Norway/depot stock + postwar Czech production) makes the re-armed-German-formation premise materially plausible at brigade-toward-division scale on a months-long ramp — matching Unthinkable's own re-equipment-lag note (§6). Documented gap: no quantified inventory of German AFVs collected in Western zones (§12).
Gate — Old-Guard Verdict required
Accept the ARQ3 findings (the old-guard inventory per bloc and the "early-phase spine" + German rear-capacity readings) as the canonical basis?
6. ARQ4 — Faction Arsenals (incl. re-armed Germans, satellites, exiles) + ARQ4b
6.1 The re-armed German question — Unthinkable's own plan, verified
Verified by fetch this sweep: the offensive would involve "American and British forces, as well as Polish forces and as many as 10 divisions of the German Army, remobilised from prisoner-of-war status" — and the planners noted the German divisions could not be re-equipped from Allied sources in time for 1 July 1945. The fuller 103-division mix (64 US / 35 UK / 4 Polish / 10 German) appears in secondary coverage medium. The 47-division Dresden attack and the force ratios (infantry divisions 80 vs 228 = 1:2.85; armored 23 vs 36; tactical aircraft 6,048 vs 11,802) re-verified (Wikipedia, fetched) high ratios carried. The re-arm lag is historical — a natural mid-phase ramp for the premise faction, with equipment capacity evidenced in §5 (Laatzen, Czech line, Norway).

6.3 ARQ4b — US Pacific rotation (the scope-note study)
The rotation is documented machinery already draining the European roster in mid-1945. high new — scope-note addendum
- The points system (Adjusted Service Rating, 12 May 1945) sorted every soldier: occupation, Pacific, or home (National WWII Museum, Wikipedia).
- ~1 million soldiers earmarked Category II for the Pacific, including 13 infantry + 2 armored divisions: 400,000 direct from Europe (arriving Sept 1945–Jan 1946) and 400,000 more via eight weeks of US retraining (arriving by April 1946) (Wikipedia).
- First Army HQ was Downfall-bound (15 divisions planned for Operation Coronet) (Wikipedia).
- Eighth Air Force HQ stood up on Okinawa 16 July 1945 (personnel from XX Bomber Command; Doolittle assumed command 19 July; first B-29 received 8 Aug 1945) — Europe's premier strategic air force was being converted to a bomber never based in Europe (Dec 1943 decision) (Wikipedia, B-29).
- Redeployment was already documented as degrading combat effectiveness — high-point veterans leaving units even as the units shipped (Wikipedia).
Inference & downstream implication (recorded, not designed here): Unthinkable's 47-division attack assumption sits inside an army already flowing east — the US roster carries historically grounded "Pacific-earmarked" pressure the campaign layer can use: formations/air groups the war either keeps (at political cost) or loses on a timetable, feeding the user's war-morale / sue-for-peace framing. Flagged for the campaign design pass. Impact on prior research: the approved premise narration already says "the greatest army America ever raised begins to leave Europe" — ARQ4b deepens that line with the documented machinery; nothing contradicts.

Schema inputs the unit/division data schema will need (input list only — no schema authoring, AR-A5): faction; category; era-band (pre-war / early-war / late-war / prototype); plausibility tier (in-theater / in-production / production-ready / prototype-in-window / paper); availability date (historical or window-projected); quantity evidence (built / in-theater / issued); phase band; source citation; reliability/readiness flags (e.g. T-44 spares, satellite dependence, Pacific-earmarked status).
Gate — Phase-Mapping Verdict required
Accept the three-band phase ladder (early/mid/late as tabled) and the schema-input list as the canonical mapping?
8. ARQ6 — Strategic-Asset Rosters (air; naval light per AR-A2)
8.1 Air rosters by faction (types and roles only)
- US: P-51D/K, P-47D fighters; A-26 attack; B-17/B-24 heavies (8th AF drawing down — ARQ4b); YP-80A pre-production jets (four in Europe); C-47 transport. B-29 Pacific-only. high (types) / medium (Aug-45 squadron states)
- UK/Commonwealth: Spitfire XIV/XVI, Tempest V, Typhoon (retiring), Mosquito FB; Meteor III in squadron service; Lancaster + Lincoln (operational Aug 1945); Vampire/Hornet production-ready 1946 (IWM 2 TAF) high
- USSR: La-7, Yak-3, Yak-9 fighters; Il-2 / Il-10 (in service from 1944) attack; Pe-2, Tu-2 bombers; 10,000+ frontline aircraft in 1945; jet generation (MiG-9/Yak-15) at the window edge (Wikipedia) high
- France: US/UK types (P-47, Spitfire) medium — not separately swept
- Re-armed Germans: Me 262 / Fw 190D / Bf 109K airframes exist in collected stocks (Lusty; NII VVS), but fuel/pilot/parts state caps anything beyond token squadrons as extrapolation flagged inference
8.2 Naval light list (deferral confirmed)
- RN: of 990 major combat units in August 1945, fewer than 300 active — 56 with the Home Fleet; demobilization already biting (naval-history.net) high
- Soviet Baltic Fleet: spent the war mine-locked in Leningrad/Kronstadt; the effective arm was the submarine force (Gustloff/Steuben/Goya); surface force two WWI-vintage battleships + light units — a coastal-flank threat, not a sea-control contender (Wikipedia, Baltic campaigns) high
- USN Atlantic: main strength concentrated in the Pacific medium — not separately swept
Inference: the naval picture confirms the naval-deferral flag is safe for the landlocked first front — naval remains strategic-map texture; the air rosters give each faction a distinct strategic-asset identity (US numbers draining, UK jet/heavy edge, Soviet mass with a late jet shelf).
Gate — Air & Naval Roster Verdict required
Accept the per-faction air rosters (types/roles depth per AR-A2) and the naval light list as the canonical basis?
9. Assumption Register Status (AR-A1–A5 after research)
| # | Assumption | Status after research |
|---|---|---|
| AR-A1 | Plausibility window ~mid-1946 | Held and validated — the window discriminates (Vampire/T-54 in; MiG-9/Yak-15 at the edge; La-9/ARL 44 flagged stretch). No re-tightening received at Stage 1. |
| AR-A2 | Ground first; air roster; naval light | Held — air covered as types/roles; the naval light list confirms the deferral is safe (Baltic Fleet no surface threat; RN demobilizing). A deepen-air option is offered at the §8 gate. |
| AR-A3 | Depth by front | Held — Central Germany factions full depth; exiles/satellites headline depth; France intermediate. |
| AR-A4 | Paper projects tier-flagged | Held — tier vocabulary carried the sweep; paper items cleanly flagged, never blended. A stricter-floor option is offered at the §4 gate. |
| AR-A5 | Feeds, does not author | Held — ARQ5 produced an input list; no schema, stats, or balance authored. |
10. Evidence Matrix
| Claim | Evidence (source · date) | Conf. | Decision impact |
|---|---|---|---|
| The marquee almost-weapons were physically in theater (Centurion, Pershing, IS-3, Meteor…) | 9-item table, multi-source · 2026-06-10 (ARQ1) | High | Reward shelf is positioning fact, not counterfactual — Pillar 2 anchored |
| The ~mid-1946 window tiers the prototype shelf cleanly | Production/trial dates per item · 2026-06-10 (ARQ2) | High (T30 date medium) | AR-A1 validated as a design rule; tier vocabulary → glossary |

Gate — Research Completeness required
Is the evidence sufficient for the canonical artifact? Known soft spots: German depot-stock totals unquantified (capacity by proxy only); T-44 count split; T30 date conflict; Soviet in-theater inventory granularity; squadron-level air OOBs not gathered (AR-A2 scope); French air / USN Atlantic medium (all listed in §11).
11. Source Coverage Gaps & Search Log
- German depot-stock inventory totals in Western zones at surrender: no quantified source found — capacity evidenced by proxies (Laatzen, Czech line, Norway brigade) only; re-armed-German scale capped at medium.
- T-44 count split (~190 by VE Day vs 940 across calendar 1945) — sources disagree; recorded as a range.
- T30 prototype completion date conflict (one capture: Mar 1945; commonly 1947–48) — medium-low; tier unaffected.
- Soviet in-theater inventory granularity (T-34-85/IS-2 counts in Germany, Aug 1945) not found; the carried division-count ratios stand in.
- Aug-1945 squadron-level air OOBs per faction not gathered (AR-A2 scope); USAAF drawdown covered via 8th AF redeployment only.
- French air and USN Atlantic state: medium, not separately swept.
- E4 genre precedent mostly carried; SD2 phase mechanics verified this sweep; WARNO deck specifics not re-verified.
- Unthinkable 64/35/4/10 division mix: secondary source only (the fetch confirms "as many as 10 German divisions" but not the full mix) — mix tagged medium.
Search/fetch log (Stage 2, 2026-06-10, main session)
10 batches, ~39 queries + 1 verification fetch (Wikipedia "Operation Unthinkable"). Batches: (1) Centurion Sentry / Pershing Zebra / IS-3 Berlin / T-44; (2) Meteor + P-80 / US heavies T28–T32 / Black Prince–Tortoise–Centurion Mk 2 / Soviet IS-4–T-54–IS-6–IS-7; (3) Vampire–MiG-9–Yak-15–La-9 / ARL 44 / Comet + Chaffee / Me 262 stocks; (4) US 75-vs-76 + TD fleet / Soviet old guard + lend-lease / Hetzer postwar / MNH-Laatzen; (5) Unthinkable German divisions / Polish People's Army / Romanian armies / exile equipment; (6) points system + Downfall / 8th AF Okinawa / Bulgarian First Army / RAF 2 TAF; (7) Soviet air / RN + Baltic Fleet / SD2 phases / Panzer-Brigade Norwegen; (8) French First Army / UK old guard / Lincoln + Hornet / Hungarian armistice divisions; (9) IS-2/ISU organization / German surrendered-stock totals (gap confirmed) / B-29 never-in-Europe / Centurion ramp; (10, closing) Pershing 310/200 / Romanian TACAM seizure / Polish II Corps state. Dead ends: German Western-zone AFV collection totals (gap 1); T30 date conflict (gap 3). Stopping rule honored: batch 10 produced only verification of already-held items — sweep declared dry.
12. Proposed Canonical File Changes (Stage 3)
| Action | Path | Content |
|---|---|---|
| Write (new) | research/arsenal-1945.md | Canonical artifact: per-faction equipment tables (§6.2), the shelf/prototype/old-guard findings (§3–5), phase mapping + schema inputs (§7), air/naval rosters (§8), with citations and gaps (§11) preserved — incl. the brief-refinement note on Romanian-vs-Hungarian satellite footing (§1.4, verified §6) and the ARQ4b downstream-implication record. |
| Archive + remove | research/_working/preliminary-arsenal-1945-research.md → docs/history/archive/2026-06-10/HHMMSS/… | Working packet retired per staged workflow. |
| Convert | alignment/arsenal-1945-omega-war.html | review → confirmed (this version archived first; approval records preserved). |
| Update | alignment/index.html | Entry status review → confirmed. |
| Append (if approved) | research/glossary.md | User-approved terms from §13 only. |
| None planned | tasks/*.md | The ARQ4b campaign-design implication flows to the campaign design pass via the canonical artifact, not a standalone task. (Consistent with Stage 1 approval.) |

| Term | Definition | Category | Decision |
|---|---|---|---|
| plausibility tier | The arsenal study's five-step evidence scale for whether an equipment item could plausibly reach Omega War's fight by ~mid-1946: in-theater / in-production / production-ready / prototype-in-window / paper. Keeps "historically inspired, not accurate" honest — paper items are allowed but always flagged (AR-A4). | domain | |
| era-band | The arsenal study's age classification of equipment — pre-war / early-war (≤1942) / late-war (1943–45) / prototype — crossed with plausibility tiers in the per-faction tables and the phase ladder. | domain | |
| reward shelf | The phase-gated late-game unlock pool of 1945–46 almost-weapons (Centurion, Pershing, IS-3, T-54, early jets) — from Pillar 2's "the 1946 arsenal gets its war": the arsenal history shelved is the payoff material the deck/phase system meters out. | domain |
