Executive Summary

AI investors bought the machines. They missed the chemistry.

The next wave of AI compute depends on a narrow layer of specialty chemicals that decide whether leading-edge wafers can be cleaned, etched, patterned, packaged, cooled, and powered at scale. Seven of the ten chemicals in this casefile gate the AI fab cascade directly. Most have only a handful of qualified suppliers. Many require 12–36 months of customer qualification before new capacity counts as supply.[15]

Capacity without qualification is not supply.

US hyperscaler capex reached a $700B+ annualized run rate in 2026, roughly seven times the 2018 level.[46] The market paid for the downstream story: Applied Materials expanded ~278% on EV/EBITDA over five years; ASML expanded ~138%. But upstream process-material suppliers gating the same buildout expanded only ~60–68%.[14]

The market paid for the machines. It has not paid for the qualified chemistry that lets the machines ship. That is the trade.

The gap exists because the market is organised by vertical. Semiconductor analysts cover tools. Chemical analysts cover industrial suppliers. Battery analysts cover cell economics. Nuclear analysts cover fuel. No single desk is structured to notice that the same fluorine chemistry sits underneath AI fabs, EV battery electrolyte, nuclear UF6 (uranium hexafluoride) conversion, and datacenter cooling fluids.

The ten chemicals in this casefile sit across four demand cascades: AI fab buildout, EV battery chemistry, datacenter immersion cooling, and nuclear restart. These cascades are unrelated in origin but share upstream chemistry. They compound the constraint rather than diversify it.

This is not a commodity supercycle. It is a qualification supercycle.

When chemistry binds, AI capex is not destroyed. It is deferred. Fab schedules slip. Packaging queues stretch. Datacenter deployments move right. Next-year capex rises to catch up. Pricing power accrues to the qualified supplier because the alternative is delay.

The thesis is falsifiable: qualification cycles could compress, Chinese or Korean suppliers could qualify faster than expected, AI capex could slow, or PFAS (per- and polyfluoroalkyl substances) regulation could impair fluorinated margins. This casefile tracks those risks through dated falsifiers and monitored claims.

Volume 1 mapped Japan’s material monopoly. Volume 2 mapped Korea’s HBM packaging stack. Volume 3 goes beneath both — to the chemical layer under AI compute itself.

The market has repriced the machines. It has not repriced the chemistry that lets the machines exist.

The Discovery Lag Mechanism

Discovery lag is the gap between when a structural constraint materialises and when capital markets price it. Sell-side research is siloed by vertical. Tokyo chemical analysts cover Stella on revenue multiples. Semiconductor analysts cover ASML on cyclicality. Battery analysts cover cell economics. Nuclear analysts cover miners on PPAs. Nobody is positioned to notice that the same fluorine chemistry enabling TSMC 2nm etch also feeds EV battery electrolyte, nuclear UF6 conversion, and datacenter cooling fluid.

This is not a demand thesis. It is a discovery-lag thesis. The constraint has not been priced because no institutional framework sees it whole. The valuation gap in Section 4 is the signature. The tier matrix in Section 8 is the trade.

The same MOFCOM apparatus controlling rare earth exports is being used offensively for energy.

One distinction matters here. The November 2025 China-US minerals truce suspended Announcements 55–62 through November 10, 2026. It did not cover MOFCOM Announcement 18 (April 4, 2025), which established the Dy/Tb/Sm/Gd/Lu/Sc/Y licensing regime. Announcement 18 remains in force.[9][6]

$700B of leading-edge AI capex ultimately depends on chemistry. The market paid for the downstream story. It has not paid for the upstream constraint.

Cascade 1: AI Fab Buildout

TSMC, Intel and Samsung are all building the next generation of chips on a new lithography machine called High-NA EUV. The machine needs a new kind of light-sensitive coating, called metal oxide resist, that prints finer lines than anything before it.[15] Around that one step sit five other chemistries. A light-triggered acid develops the pattern. A glass-like filler keeps the chip stack from cracking. The wafer itself is cleaned with a twelve-nines-pure acid. A fluorine gas scrubs the chamber between layers. Above it all sits a carbon-film cover that protects the photomask from a 600-watt laser. Each one is a different supplier. Each one has to qualify for years before it ships. None can be skipped.

Cascade 2: EV Battery Chemistry

China controls about 95% of global LiPF6 (lithium hexafluorophosphate, the primary Li-ion electrolyte salt) production — output reached 187,000 tonnes in 2024, up 45% year on year.[17] Any non-China LiPF6 plant gates on anhydrous hydrofluoric acid, putting battery electrolyte in direct competition with AI fabs at the fluorine layer. LFP cells — which now hold ~85% of stationary battery energy storage and grew 51% in 2025[16] — also use LiPF6, compounding the demand pull.

Cascade 3: Datacenter Immersion Cooling

A major US chemicals incumbent ceased production of its rival immersion-cooling fluid at end of 2025,[11] withdrawing an estimated $1B+ of annual specialty fluid supply. Demand has redirected to a handful of remaining producers in Europe, the US and Japan.

Cascade 4: Nuclear Restart

Reactor fuel starts as a gas called UF6 — uranium hexafluoride. Before uranium can be enriched, it has to be converted to this gas. In January 2026 the Department of Energy split a $2.7B contract three ways to rebuild that capability in the West.[4] Only one US plant can do the conversion today. The plant returned to public markets via spinoff and the uranium contract drove the re-rating. The acid exposure did not. The same plant consumes ultra-pure hydrofluoric acid to do the conversion, putting it on the AI fab supply chain too.

The Qualification Moat

Seven of the ten chemicals gate AI fab specifically, each carrying a 12–36 month qualification cycle that no amount of capex can compress.[46] If any one of them binds, capex gets deferred, not destroyed. No hyperscaler can accept multi-quarter delays to AI roadmaps capitalised at 30–50× forward earnings.

The market paid for the downstream story. It hasn't paid for the upstream constraint. See Appendix A.4.

The 5-Test Severity Filter

A chemical qualifies as a structural chokepoint only if it satisfies all five tests simultaneously. Full test definitions: Appendix A.5.

Each entry names the 5-test result, producer landscape, and cascade attribution. Cross-references: ABF (Chem 8) per the Japan analysis; Namics MR-MUF (Chem 5 context) per the Korea HBM analysis.

1. 12N Ultra-High-Purity Hydrofluoric Acid (UHP HF)
SEV 4 AI FAB EV BATTERY NUCLEAR
3 CASCADES

Every silicon wafer has to be cleaned and etched with an acid so pure it has only one impurity per trillion atoms. The same acid is the precursor for lithium battery electrolyte and for converting uranium into reactor fuel. No substitute exists at this purity. A small handful of producers globally are qualified at this purity grade. Chinese suppliers can produce hydrofluoric acid, but not at the purity grade the leading-edge fabs accept. 5-test: 4/5. It is the only chemical in the casefile load-bearing across three cascades.

A 2025 fire at one of the main production lines forced emergency notices to the leading logic and memory fabs.[7] A second producer exited the business shortly after, further tightening supply. 5-test: 4/5.

When the EUV machine prints a wafer, a thin transparent film called a pellicle sits over the photomask to keep dust off. The next generation of EUV runs at 600 watts — hot enough to vaporise the silicon film used today. Only one material survives at that power and stays transparent: a film woven from carbon nanotubes. Two suppliers cover the market globally. 5-test: 4/5. Not 5 — ASML has not formally certified the 600-watt step yet.

At the end of 2025, a major US chemicals producer discontinued its rival fluid, removing an estimated $1B+ of equivalent supply (industry estimate).[19] A handful of producers remain globally. PFPE is not the PFAS regulators are banning. The risk over the next two years is price, not prohibition. 5-test: 4/5.

Before uranium can be enriched into reactor fuel, it has to be converted to a gas: UF6. The centrifuges that do the enrichment will not run on anything else. Russia used to supply about 30% of the West’s UF6. That supply was banned by US law in August 2024, with waivers running out in 2028. Every hyperscaler nuclear deal on the table — Amazon’s investment in advanced reactors, Microsoft’s restart of Three Mile Island, the DOE’s $2.7B HALEU contract — routes through UF6.[28] The only US conversion plant returned to public markets via spinoff. Building a new NRC-licensed conversion plant takes five to ten years. 5-test: 5/5.

Worked Example: Stella Chemifa — Discovery Lag in One Company

Stella Chemifa (4109.T, TSE) is a small Japanese specialty chemical producer that illustrates the discovery-lag mechanism behind this casefile.

The market typically sees Stella as a niche chemical supplier. The graph sees something different: a company sitting near multiple qualification-gated chemistry layers, including ultra-high-purity hydrofluoric acid, lithium battery electrolyte chemistry, and fluorination pathways relevant to the nuclear fuel cycle.

The core moat is 12N UHP HF. Patent WO2005092786A1 covers the purification process required to reach twelve-nine purity at semiconductor-etch yield. When a Korean second-source attempted an emergency ramp in 2020, it took 18–24 months to qualify at the leading Korean memory fabs.[20] Qualification relationships built over decades are not easily displaced.

The important point is not that Stella alone controls the system. It is that companies like Stella are evaluated by narrow sector frameworks while their dependencies span AI fabs, EV batteries, and nuclear restart. No single sell-side desk naturally owns that combined map. That is the discovery lag.

The key uncertainty is substitution. Korean and Chinese suppliers have improved materially since the 2019 Japan export restrictions, and the leading Korean second-source remains the most important partial counterexample. Its US plant does not complete until 2029.[29] If alternative qualified supply emerges faster than expected, the thesis weakens.

Full equity analysis, valuation ranges, cascade payoffs, customer exposure, and dated catalysts are available in Section 8 (Pro).

Cascade Engine Validation

Japan just gave us a live test of the ForcedAlpha graph.

Reuters reported that Japanese firms reliant on naphtha-based products faced supply disruptions following the Middle East crisis that began in February 2026. Some companies suspended orders, adjusted deliveries, or raised prices. One industry survey found only 2.7% of firms could obtain thinner as usual.[R1]

That matters because naphtha is not just an energy input. It is a base-layer petrochemical feedstock. It flows into solvents, resins, plastics, intermediates, coatings, adhesives, and parts of the specialty chemical stack.

Our graph had already identified the structural issue before the headlines: Japanese specialty chemical companies are overrepresented among the most systemically important nodes in the AI compute supply chain.

9 / 20
of the most systemically critical supply-chain nodes
are Japanese companies
The Japan-removal scenario only disconnects a modest share of total demand paths. But that misses the real risk. The nodes that matter are not average nodes. They are qualification-gated, low-substitutability chemical suppliers sitting upstream of semiconductors, memory, gases, etchants, and process materials.

Japan does not create the largest number of broken paths. It creates the highest-value broken paths.

That is why simple country-risk screens miss it. The relevant question is not “how much of the graph breaks?” It is “which irreplaceable paths break?”

The cascade engine quantified this structurally using DebtRank (Battiston et al. 2012), adapted for supply chain graphs. The algorithm removes a single node, then propagates shock through every downstream dependency, weighted by substitution friction and qualification time. The result: systemic asymmetry exceeding 20,000:1 — the ratio of downstream exposed value to upstream market capitalisation.

For every dollar of upstream supplier market value, twenty thousand dollars of downstream demand depends on it. That is the asymmetry.

Method note: downstream exposure is capped at unique terminal demand nodes and deduplicated by company identifier. Intermediate supplier market caps are not summed. The asymmetry ratio is downstream terminal exposure divided by upstream node market capitalisation.

The naphtha shock is not the thesis. It is a live stress test showing how feedstock disruption exposes the same supplier geography the graph had already marked as structurally important.

The acute naphtha crisis may be managed. Japan now says it has secured supply into next year.[R2] But the structural vulnerability remains: the same cluster can be hit by naphtha, tungsten, earthquakes, export controls, shipping disruption, or qualification delays.

This is why supply-chain alpha is not about predicting one headline. It is about knowing which obscure node becomes non-obvious leverage when the headline arrives.

What the cascade engine adds
The ten chemicals in this casefile were selected by the 5-test severity filter. A separate cascade-engine run produced a convergent signal: Japanese specialty-chemistry suppliers ranked among the highest systemic-alpha positions in the graph. The methodology is different. The conclusion is the same: the chemistry layer is load-bearing.

Counter-Thesis & Falsifier Ledger

Eight conditions that would weaken or falsify this casefile. Each card names the risk, the rebuttal, and the specific evidence that would trigger falsification.

SC-001
Qualification cycles remain structurally long (12–36 months) at leading-edge fabs
Risk: A Korean second-source qualified at Korean memory fabs in ~18–24mo under 2019 emergency. Compression has not been demonstrated at sub-5nm; 2019 involved mature chemistry. High-NA MOR, CNT pellicle, 12N HF at 2nm have no equivalent precedent.
Falsified if: any of the 10 chemicals achieves fab qualification in under 12 months at TSMC, Samsung, or Intel. Check: quarterly earnings calls, SEMI.
Pending
SC-002
No second-source producer qualifies for UHP HF at a non-Chinese leading-edge fab before Q4 2027
Risk: A Korean second-source has qualified at Korean memory fabs and is building US capacity.[29] Current qualification remains Korean-domestic; TSMC relationships not publicly confirmed.
Falsified if: a Korean, US, or European UHP HF producer achieves SEMI Grade 5 qualification at TSMC, Samsung, or Intel before December 31, 2027.
Pending
SC-003
Combined hyperscaler capex guidance stays above $500B through 2027
Risk: HBM oversupply was flagged in 2025; capex decline before 2nm/High-NA ramps could defer chemical demand 12–24mo. But capex slowing affects timing, not structural dependency. Qualification moats persist and produce asymmetric upside when the cycle resumes.
Falsified if: combined Amazon + Google + Meta + Microsoft capex guidance for 2027 drops below $500B in any Q3 or Q4 2026 earnings call. Source: 10-Q filings, Bloomberg.
Pending
SC-004
EPA PFAS restrictions do not extend to semiconductor process chemicals before Q2 2027
Risk: EPA April 2024 PFBS MCL plus EU REACH could impose liability on PFPE. But high-MW PFPE is regulatorily distinct from short-chain PFAS targeted in current rulemaking. No PFPE is on the EPA MCL; EU REACH explicitly differentiates high-MW fluoropolymers.
Falsified if: EPA finalises PFAS restrictions that explicitly cover semiconductor-grade fluorinated process chemicals before June 30, 2027. Source: Federal Register, EPA docket.
Pending
SC-005
Hybrid bonding does not displace underfill in more than 50% of advanced packaging by 2028
Risk: Besi hybrid bonding could remove underfill in future stacks. But hybrid bonding is in leading-edge logic only (Foveros, SoIC); HBM-4 16-high via hybrid bonding is post-2027 roadmap. HBM-3E and initial HBM-4 still use underfill.
Falsified if: TSMC or Intel announce >50% of advanced packaging volume will use hybrid bonding by the 2028 node. Source: earnings calls, IEDM papers.
Pending
SC-006
LiFSI does not exceed 20% of electrolyte salt market share
Risk: LiFSI has better thermal stability. But LiFSI is ~1% (2022) → ~9% (2025) as additive, not replacement.[18] Full substitution requires closing a 3–5× cost differential; low probability on a 5-year horizon.
Falsified if: LiFSI share exceeds 20% in any quarterly report from CATL, LG, Samsung SDI, or Panasonic. Source: Metal.com, SNE Research.
Pending
SC-007
No Korean government dual-source qualification programme for UHP HF launches before 2028
Risk: Korean MOTIE could subsidise a second domestic UHP HF producer. Chinese progress in i-line/KrF, with no EUV fab qualification as of Nov 2025.[22] CXMT is limited to low-spec memory; High-NA MOR requires IMEC tool-resist co-optimisation, not replicable by formula access.
Falsified if: Korean MOTIE announces a dual-source qualification subsidy AND a second Korean producer achieves qualification at a leading-edge fab. Source: ministry releases, Korea Times.
Pending
SC-008
Aggregate specialty chemical capacity additions do not exceed 30% of installed base by Q2 2027
Risk: Multiple Japanese specialty incumbents and the Korean second-source have active expansion programmes. But new capacity must be re-qualified per customer, adding 12–24mo to revenue realisation. The structural constraint that limits supply growth is the same mechanism that creates the moat.
Falsified if: announced capacity expansions across all 10 chemicals exceed 30% of installed base by June 30, 2027. Source: TrendForce, company filings.

Chinese producers of LiPF6, NF3, and spherical silica may be closer to leading-edge qualification than public data suggests. SEMI and TrendForce coverage of Chinese specialty chemical capacity is structurally incomplete. This casefile assumes current qualification barriers hold through 2027. That is the weakest assumption.
Private company capacity data
Several key producers are private or sit inside diversified conglomerates. Capacity utilisation and expansion plans are not available from public filings. The thesis relies on industry estimates and press releases where disclosure is absent.
High-numerical-aperture EUV pellicle timeline uncertainty
CNT pellicle HVM qualification is estimated at 2027 and beyond, but depends on ASML’s High-NA EUV adoption timeline, which has slipped multiple times. If adoption delays significantly, this chokepoint may not bind until 2028–2029.
Cross-chemical substitution effects
This casefile treats each chemical as an independent chokepoint. In practice, a process change at one node (say, replacing oxide etch chemistry) could reduce demand for adjacent chemicals. Those second-order effects are not modelled.

Supply Chain Intelligence Graph — Volume 3 Build Verified
Nodes3,272 (companies, materials, policy actors, facilities, mechanisms)
Edges11,660 supply chain relationships
Graph algorithmsDirected cascade traversal (graph traversal forward from material nodes), bridge node detection, single point of failure analysis, betweenness centrality (a measure of how often a node sits on the shortest path between others in the network), hop-level market cap aggregation
Severity index1 (commodity, many suppliers) to 5 (structurally binding at current margin). Derived from supplier concentration, qualification timelines, and cascade exposure counts.
Chemical selection criteriaInclusion requires all five conditions simultaneously: (1) no functional substitute within a five-year horizon; (2) IP or process-embedded moat; (3) qualification cycle exceeds 12 months; (4) six or fewer qualified global producers; (5) cascade-critical exposure (serves ≥2 cascades, or gates a non-substitutable step inside a single cascade with >$100B downstream capex and >12-month qualification cycle). Severity 5 modifier for single-facility or single-country concentration.
Sourcing standardEvery factual claim is tied to a primary or tier-1 secondary source (company filings, USGS, MOFCOM notices, SEMI, TrendForce, imec, DOE press releases). Severity 4–5 ratings require named competitor evidence and market share sourcing. Claims that cannot be verified are either removed or explicitly qualified.
Data sourcesUSGS Mineral Commodity Summaries (annual), MOFCOM official announcements, SEMI industry reports, TrendForce semiconductor intelligence, imec High-NA EUV research disclosures, company filings and annual reports (10 specialty chemical producers), DOE HALEU program disclosures, EU REACH regulatory guidance, EPA PFAS rulemaking

Appendix

A.1 — Chokepoint Map: Four Cascades, Ten Chemicals

Full interactive map showing how the four demand cascades (AI fab, EV battery, datacenter cooling, nuclear restart) converge on the same ten specialty chemicals.

A.2 — Qualification Cycle Detail by Tier

12 months (entry-tier): Standardized specs, multiple qualified suppliers, process-tolerant. Commodity HF below 12N purity, standard photoresist for mature nodes (i-line, KrF), basic CMP slurries. 8–15+ qualified suppliers globally. Competition is on price and delivery.

18–24 months (advanced purity): Requires multi-fab validation, process integration testing, yield impact verification. UHP wet chemicals, ArF immersion photoresist, NF₃, PAGs, spherical silica filler, semiconductor-grade graphite. 4–8 qualified producers. Qualification involves full process integration, not just chemistry testing. One Korean producer documented an 18–24 month development-to-supply cycle after the 2019 Japan export restriction.

24–36 months (critical-node): Requires ASML or chipmaker sign-off, multi-generation process validation, no yield regression. 12N UHP HF (full semiconductor-grade spec), EUV chemically amplified photoresist, ABF substrate resin (foundry CoWoS process lock), underfill resin (HBM stack spec-locked), PFPE immersion cooling fluids. 1–4 qualified producers at required spec. Most concentrated node has a single qualified production site globally.

36+ months (regulated / defense-grade): Qualification requires regulatory framework completion and government sign-off. UF₆ conversion for enrichment feed (NRC license minimum 3–5 years), HALEU UF₆ (additional NNSA oversight), next-gen EUV pellicle membranes (equipment OEM certification required, HVM qualification estimated 2027+). 2–4 globally. No new entrant has qualified in 15+ years for UF₆ or HALEU conversion. No greenfield UF₆ conversion facility has been permitted in the US since the 1970s.

A.3 — Bear Case: Glass Substrate Substitution (ABF Resin)

Intel, Samsung Electro-Mechanics (SEMCO), and SKC/Absolics are developing glass core substrates as a potential replacement for ABF in advanced packaging. Glass offers lower warpage, higher thermal stability (~400°C vs ~150–180°C), and finer via pitch. Intel demonstrated a thick-core glass substrate with EMIB at NEPCON Japan (January 2026); SEMCO formed a JV with Sumitomo Chemical (November 2025) and targets 2027 ramp.

As of mid-2026, no glass substrate is qualified for high-volume manufacturing. Key barriers: glass brittleness, entirely new process infrastructure (laser drilling, metallization), and the need for full re-qualification at the leading-edge foundries. The ABF incumbent is simultaneously expanding capacity ~50% by 2030, suggesting the industry is hedging rather than committing to a near-term transition.

Within this casefile’s horizon (through late 2027), glass substrate does not appear to threaten ABF’s severity-5 rating — but a successful Intel HVM qualification would change that assessment.[47]

A.4 — Valuation Gap: Downstream vs. Upstream

The market paid for the $700B funnel via NVIDIA, ASML, AVGO, AMAT multiples. It hasn't paid for the chemistry layer gating whether the $700B converts to deployed compute on schedule. That gap is the trade.

Price-action evidence (3-year, indexed): Tool-maker indices ran +253% while a representative Japanese specialty-chemistry name supplying the same AI fab build-out ran +86% — a 167-point spread. NVIDIA ran +616% over the same window; one Japanese photoresist incumbent delisted in early 2024 before the gap could close, and the photoresist layer has not re-rated since. The exception is instructive: Stella Chemifa matched ASML (+130% vs +131%) — the one pair where allocators noticed, the spread compressed.

EV/EBITDA context (5-year): Tool-maker multiples expanded from approximately 9× to approximately 34× EV/EBITDA; the comparable Japanese specialty-chemistry name expanded from approximately 4× to approximately 6.4×. Different lens, same structural gap.[14]

A.5 — 5-Test Severity Filter: Full Definitions

  1. No functional substitute — no alternative chemistry performs the same role at equivalent cost, yield, and process compatibility within a five-year horizon
  2. Intellectual property and process protection — the moat is embedded in formulation know-how, purity specifications, or proprietary synthesis routes, not commodity processing
  3. Qualification cycle exceeds 12 months — requalification after a supplier change requires more than one year of testing across process steps, device architectures, or manufacturing conditions
  4. Six or fewer qualified global producers — the set of suppliers capable of meeting leading-edge purity or performance specifications at production scale
  5. Cascade-critical exposure — the chemical either serves two or more demand cascades, or gates a non-substitutable step inside a single cascade with more than $100B of downstream capex exposure and a qualification cycle exceeding 12 months

Severity 5 modifier: applies to single-facility production globally, single-country patent enforcement, or confirmed greater than 90% one-company market share with no qualified commercial alternative.

A.6 — Stella Chemifa: Discovery Lag Detail

The dual cascade exposure creates a structural position no other sub-$1B name in this layer occupies: AI fab, EV battery, and nuclear fuel all pull on this producer simultaneously. Both the battery and nuclear chain openings postdate the multiple's historic range. Tokyo specialty chemical analysts do not simultaneously track TSMC process chemistry, EV electrolyte chains, and nuclear fuel cycle. The discovery lag made concrete.

A.7 — Validation Trail

Multi-pass research and critique process. Framing evolved from “Japan specialty chemical risk” to “four uncorrelated demand cascades converging on the same narrow chemistry base.”

  1. Supply-side sourcing: 10 chemical data packs verified against USGS, MOFCOM, SEMI, TrendForce, imec, company filings. Producer landscapes confirmed with named competitors. China concentration percentages sourced with publication dates.
  2. Demand-side sourcing: Four cascade assignments verified — specifically testing that each chemical is a genuine non-substitutable input to the cascade application, not a commodity input.
  3. Internal critique pass: LiFSI substitution timeline quantified and elevated to counter-thesis. Korean second-source US-capacity falsifier added. Eight falsifiers documented in SC ledger.
  4. Graph topology review: Cross-cascade chemical matrix confirmed via directed traversal from 4 cascade seed sets. Discovery-lag valuation gap validated against StockAnalysis.com and AlphaSpread.
  5. Domain sanity check: Material science claims, production processes, and regulatory timelines verified against primary sources. Corrections applied where needed.

A.8 — Claim Confidence Tiers

Every factual claim in this casefile is tagged with one of three confidence tiers. Border colours on key statements correspond to the tier system below.
