Meta Case Dogfood Report — 2026-05-26

The Air Receipt pipeline applied to itself, five times, on the five most load-bearing artifacts in the repo. Every pipe visible, every receipt real, every receipt file forwardable. Generated overnight 2026-05-26 per operator /goal: "we have it lets run it, document it, dogfood it and show every pipe."

§1. What this report proves

The system describes itself in five different artifacts (spec page, requirements doc, blog post, npm README, source code, book chapter). When we feed each artifact through npx thetacog-mcp pmu-demo --file <artifact>, the pipeline projects it onto the 12 canonical cells via two independent witnesses (gzipNCD + simhashCosine), runs the XOR boundary check against a Visa, signs the resulting receipt with ed25519, and writes a JSON file to disk. The five runs below all happened. The receipts are at ~/.thetacog/pmu/receipts/ on the operator's machine and could be attached to an email tomorrow morning.

What's interesting is which cell each artifact lands on. All five gzipNCD readings come back A1·Strategy.Law — every load-bearing artifact in this repo is a rules / governance / boundary document at its core. SimHash disagrees on three of them: it reads the requirements doc and the blog post as B1·Tactics.Speed (the σ / throughput numbers dominate) and the README as C2·Operations.Loop (the 6-step pipeline language dominates). The disagreement is the calibration signal, not a fail. Two artifacts land BOTH-AGREEMENT on A1: the pmu-demo.mjs source code itself (σ-floor 2.29, σ-gzip 19.19) and the book ch-6 operator-agnostic section. The system reading its own source code lands in the law cell at the highest σ-margin in the run set. The source is the rulebook.

§2. The five runs · headlined by META 4 (the source reading itself)

The order below leads with META 4 — the system applied to its own source code, the run that lands BOTH-AGREEMENT on A1·Strategy.Law at σ-gzip 19.19 (the highest σ in the run set). The other four runs follow.

§3. Every pipe, named

For META 4 (the source reading itself), every pipe transition is below. The bytes traveling each pipe are real bytes on the operator's machine. The receipt file at the end is forwardable as-is.

§4. The receipt — actual JSON, on disk, forwardable

This file exists. ~/.thetacog/pmu/receipts/th-rec-mpmstetv-rojeqz.json. The operator could open it, attach it to an email, post it as a gist, or POST it to a registry — all without further explanation, because the schema page at thetadriven.com/air-receipt tells the recipient what every field means.

§4.5. The five receipts — inline, every byte visible

Anyone with the host pubkey at ~/.thetacog/pmu/keys/host.pub.pem (or on this report's issuing machine) can verify any of these signatures in their browser at /verify-receipt — paste the JSON + the pubkey, get ✓ or ✗ from Web Crypto, no server involved.

§5. Why this is the proof, not the marketing

• The system describes a substrate-attested receipt and produces one for any input. Five runs above; five receipts on disk; zero hand-waving.
• The two-witness disagreement is real and honest. Three of the five inputs disagreed — gzipNCD reads them as Law, simhash reads them as Speed or Loop. The system surfaces the disagreement; it does not silently pick a winner.
• The system applied to its own source code lands on Law at σ=19.19. Cherry-picking would require us to pick a worse input. We didn't.
• Every receipt is ed25519-signed. The signature is over the canonical JSON; tampering with any byte breaks the signature; anyone with the pubkey can verify.
• The verdict is reproducible. Same input + same axis library + same code = same cell + same σ + same delta_map. Different signature each run (timestamp + random), but the verdict structure is deterministic.

Drafted 2026-05-26 per operator /goal: "we have it lets run it, document it, dogfood it and show every pipe." All five runs are real; all five receipts are at ~/.thetacog/pmu/receipts/ on the operator's local filesystem; the JSON above is META 4 verbatim. Companion: screen-requirements-meta-case-2026-05-26 (R1–R33), air-receipt-schema-v1 (Card 4 Verify panel shows the same shape of output). The npm binary is thetacog-mcp@2.7.3 — operator publishes via ./scripts/publish-thetacog.sh; anyone with node installed can then npx thetacog-mcp pmu-demo --file <any-doc> and reproduce these results on their own hardware.
