The published 2026 construction-AI case corpus is overwhelmingly vendor-led (Procore, Autodesk Construction Cloud, OpenSpace, Buildots, Doxel) with thin named small-contractor self-published cases. Reading the vendor corpus honestly, three workflows now show consistent under-100-employee contractor AI deployment (estimating speed via takeoff acceleration, schedule risk surfacing, as-built reality capture); a fourth (AI safety detection) remains structurally biased toward larger sites with the camera coverage and safety officer to act on alerts.
Re-review 10 Jun 2026: all five vendor corpus anchors live and unchanged (Procore, Autodesk Construction Cloud, OpenSpace, Buildots, Doxel — all HTTP 200); no named small-contractor self-published case study surfaced that would shift the vendor-led corpus reading; the 30-50% estimating time saving remains vendor-published and is labelled directional in both claim note and article. Claim holds unchanged. Path B operator case-study piece, vendor-corpus-heavy because small construction firms rarely publish. Defensible 25-employee specialty contractor stack: one PM platform (Procore, Fieldwire, or Buildertrend) + AI-assisted estimating add-on + reality-capture if multi-site or warranty exposure + Enterprise AI assistant for project documents. Vendor-published 30-50% estimating time saving treated as directional, not measured.

About this register
The Operators register tracks claims published from practitioner-advisory pieces addressed to solo founders, micro-SMB, and small businesses up to around fifty people. Claims are reviewed on a 30–45 day cadence — tooling and SMB-relevant pricing shift faster than enterprise procurement signals.

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.

Trigger condition (2) fired: the effective date moved. Governor Polis signed SB 26-189 on 14 May 2026 (Holland & Knight client alert, May 2026; Seyfarth; Littler). The signed law repeals and reenacts the original Colorado AI Act and its obligations take effect 1 Jan 2027 — not 30 Jun 2026 as the claim asserted. No operator obligation starts 30 Jun 2026; the only pre-2027 item is Colorado AG rulemaking due by 1 Jan 2027. The claim's structural reading holds (risk-management programmes and impact assessments dropped for a notice-and-transparency framework; consequential-decision scope covering employment, housing, credit, insurance, education, healthcare; no small-firm exemption). The urgency leg ('obligations from 30 June 2026') is overtaken. Status Up → Partial.
