For EU-based solo developers doing client work in 2026, the procurement-defensible AI-tool posture turns on client-code data residency rather than on Cursor-vs-Copilot-vs-Claude-Code feature comparison. All three dominant AI coding tools support EU data residency at Enterprise tiers (Copilot via Microsoft Azure OpenAI EU regions, Cursor via configurable LLM provider routing, Claude Code via Anthropic API EU-region availability). Three contract clauses now appear in regulated EU client agreements: client-code-non-transmission, EU-residency requirement, and sub-processor disclosure. The procurement-defensible workflow has five steps: AI-tool inventory, per-client risk assessment, configure tools per client, document configuration in engagement contract, audit quarterly. Three scenarios where the right answer is to disable AI tooling entirely: explicit contract prohibition that cannot be negotiated, embedded regulated data in the codebase, national-security or jurisdictionally-sensitive code.

Source-text re-review: the '$300-$500 (2024) toward $100-$130 (early 2026)' median trajectory is not stated in either cited source — the Godberry Studios teardown reports stack cost by revenue tier (not a year-over-year median) and BetterCloud's SaaS-industry data covers enterprise spend, not solopreneur AI subscriptions. The compression direction is supported by the Godberry tier data and observable foundation-model bundling; the specific year-anchored median figures are reclassified as source:our-estimate in the article. The load-bearing claim (active compression / category-collapse) holds; status moved to Partial pending a primary source carrying a dated solopreneur-median series.

One named member of the generation cluster was already defunct at publication: Tome shut down its presentation/narrative product (Tome Slides) in March 2025 and pivoted to sales tooling, with the brand later sold to AngelList (deckary.com shutdown timeline; signalhub.substack.com post-mortem, both checked 10 Jun 2026). The generation cluster reduces to Pitch + Gamma. The two-cluster thesis itself is unaffected and arguably strengthened — the pure AI-narrative product failed to find a sustainable business while Gamma (70M users, $100M ARR as of Nov 2025) and the assembly cluster (PandaDoc, Better Proposals, Proposify per Luniq 2026 agency comparison) both compound. Status Up → Partial for the factual error in the tool list.

Vendor attribution error in the claim text. The claim names Polley Faith among 'Spellbook with named small-firm customers Westaway, KMSC Law, Polley Faith'. Polley Faith LLP is a Harvey-listed law-firm customer, not a Spellbook customer: the live Spellbook site (now spellbook.com; spellbook.legal 301-redirects) names Westaway, KMSC Law, and McInnes Cooper with no Polley Faith, and the source article's own body correctly places Polley Faith on Harvey's roster — the claim text and the article excerpt bundled it with the wrong vendor at publish. The remaining legs verify against extracted source text on 10 Jun 2026: Anthropic's GC AI customer story carries 'More than 1,500 companies' and '14 hours saved per week on average ... based on a survey of more than 100 active customers' verbatim; Harvey's published roster (Thompson Hine, Fox Rothschild, Lowenstein Sandler, Polley Faith) matches; ABA Formal Opinion 512 remains the governance baseline. The corpus reading (AI ships at 1-to-20 lawyer scale; privileged work stays on Enterprise-tier zero-retention access) is unaffected. Status Up -> Partial.
