What this project has actually found

Thefindings.

The research log is chronological, which is right for a record and wrong for finding anything. These are the entries worth reading on their own.

Every word below is read out of research-log.md — this is a second view of that file, never a second copy, so the two cannot drift apart. Each finding states what was held, what was done to test it, what came back, and what the change cost. Entries that cost nothing are not findings. Several of these are positions this project withdrew.

  1. 2026-08-18 opened L-020

    A figure taken from a search summary was wrong in the exact shape this project had just finished criticising

    Two failures, not one. The figure had not been pulled from any filing — it came from a WebSearch result summary.

    The chassis repeal has a companion provision with a date on it, and the date is eleven months away

    Section 301 did not stop at the definition. Section 301(c) added subsection (i): every state must certify by 11 July 2027 — two years where a legislature meets biennially — that its own laws subject a chassis-free home to the same treatment as a chassis one, "including with respect to financing, tit

    The certification the Act demands is parity, and parity with a vehicle title is still a vehicle title

    The obligation is parity, not reclassification, and the parity runs to the state's own definition: a state certifies that its laws "treat any manufactured home in parity with a manufactured home (as defined and regulated by the State)".

    The model residential code deletes, but never fast enough to shrink — two cycles measured, both ended larger

    Deletion is real and small; growth is steady. 2015 carries 58 deletion indicators against 2,993 sections. 2018 carries 42 against 3,064 — a net gain of 71 sections over 2015.

    Adoption of a compiled determination is won at a state legislature, not sold to a building department

    It has been offered, and it is nineteen years old. Florida Statute §553.791 lets an owner or contractor use a licensed private provider for plans review and inspections in lieu of the local building department, with statutory insurance minimums, a twenty-business-day clock, and a 2025 amendment expr

    Encoding cost is what closed this market, and it has collapsed

    Refuted. Singapore's checking engine was transplanted — a Norwegian pilot on the e-PlanCheck base, a completed New York City pilot on ICC codes, testing with Japanese and Australian models.

  7. 2026-08-09 withdrawn L-004

    Housing supply constraints cost the US economy a measurable share of output

    Two things were wrong. The 36 / 14 pair is not the paper's own result — it comes from compounding annual rates, which yields level effects rather than growth forgone.

    American housing is an industry of projects, not products, and the binding constraint is approval duration

    The diagnosis half has held through everything below. The claim about what causes the duration, and what would remove it, has not.

    Compiling the rules is the thing nobody has done

    Both halves were wrong. Compiled-rule products already exist and several are already builder-facing: Symbium covers California accessory-dwelling rules statewide with address-in, envelope-out determinations; Buildability claims parcel screening across 3,100+ counties; Canibuild sells site-fit and au
