# What this lane got wrong, what it would have claimed if nothing had stopped it, and what you will find in the first hour Written 2026-09-04, at the end of the program, and rendered verbatim on the site. Every item names the receipt that proves it and, where a check caught us, the check. Nothing here was found by a customer. **If anything on our public surfaces contradicts this file, this file is right.** The estate's whole argument is that you can check us. This is the part of the argument that costs something. --- ## Part 1 — What we would have claimed, and the check that stopped us Each row is a sentence this lane had written down, or would have shipped, and the specific instrument that took it away. **"270 PASS / 9 NA / 3 FAIL on the acceptance ladder."** Never true against committed evidence. Regenerating the ladder from the certificates themselves gives **267 / 9 / 6**. Two of the extra failures are rungs asserting a pre-fix attack the keyed certificate cannot satisfy, and they were left red rather than re-specified to pass. *Caught by:* running the ladder's own producer instead of quoting its output. *Receipt:* `reports/statefabric_acceptance.md`. **"Six sealed pre-registrations."** There were five, and counting the sealed files returns 5 at every commit — `git log --diff-filter=DR` shows none was ever deleted, so the six was never true of tracked files at any point. *Caught by:* re-executing the entry's own quoted command instead of trusting the quote (`scripts/check_top40_excerpts.py`). *Receipt:* `reports/STALE_CLAIMS.md` §9. **"Reproduce it with `make ebpf-gate`."** That target does not exist and never did; the command would have failed with `No rule to make target`, not with the platform message the entry gave. The existing command gate could not see it, because it only parsed `.py`/`.sh`/`.tcl` names. *Caught by:* a gate written specifically because the old one was blind to `make` targets (`scripts/check_top40_make_targets.py`). A second entry, rank 34, had the same defect. **"192.2× cross-caller sharing in SGLang," as a headline.** The measurement is real — 769 tokens against a baseline of 4 — but its own seal required **four** controls including a capacity read that would rule out eviction *by measurement*, and the certificate reports `engine_capacity_reported: false` **while also reporting `ALL_CONTROLS_PASS: true`**. Three of four is not four. *Caught by:* `scripts/check_prereg_controls.py`, which reads the seal and the certificate and compares them rather than trusting the certificate's own summary flag. The entry is marked OVERCLAIMED by our own peer review, it does **not** open the site, and the contradiction between those two fields is still in the artifact rather than smoothed away. **A false "REPRODUCED" receipt on the eBPF gate.** Run on this macOS host, the producer exited 0 in 1.1 seconds and **overwrote** its own certificate with a blocked record, so a touch-based gate graded it REPRODUCED. *Caught by:* the external kit's gate 4 combined with reading what the producer actually wrote. Fixed at the cause — the producer now refuses to write off-Linux — not by adjusting the gate. **"$43.6M/yr in fleet savings."** Withdrawn. The certificate carrying it was set to `certified: false` on 2026-07-31 with a note saying a certificate cannot certify a claim it has withdrawn — and a `make verify-all` run on 2026-08-26 regenerated the file with `certified: true` and the note **deleted**, because the generator computes the flag from data and never emits the retraction. *Caught by:* diffing the working tree against committed bytes before trusting either. The e-value behind the number also grows with n by construction, so it is not valid under optional stopping. **"We lowered a machine-checked tenant gate into the kernel."** The generator's own comment says the XDP entry exists "so the object is loadable on Linux." A sibling lane loaded that exact object on a live 6.8.0-117-generic kernel and the verifier **rejected** the combiner at instruction 0 with `R2 !read_ok`. The gate is a compiled four-argument function; a BPF program starts with one initialised register. **The object holds a gate that is not a loadable program and a loadable program that is not the gate.** *Caught by:* another lane's rig, a third lane's sealed prediction made before anyone loaded it, and our own byte-level decode on a host with no verifier — three derivations, no contact. *Receipt:* `results/data/statefabric/ebpf_kernel_verdict_2026-09-04.json`. **A prompt-cache timing AUC measured against a null of 0.5.** Three sealed runs voided themselves under their own negative control. The last put two never-cached, **token-identical** classes at **AUC 0.607, CI [0.5198, 0.6943]** against a sealed band of [0.40, 0.60]. So 0.5 is not this instrument's null, and the 2026-07-21 certificate our headline half rested on never ran that arm. *Caught by:* the control we had sealed ourselves, firing three times. We stopped spending rather than reinterpreting the bar after seeing the result. *Receipt:* `NEGATIVE_RESULTS.md`. **"The seal was committed before the certificate," about the result that opens our site.** We wrote that sentence and then measured it. For QLoRA the seal and the certificate entered this repository **in the same commit, delta 0 seconds** — git ordering establishes nothing. *Caught by:* a check we added while building the site package, which recomputes the interval instead of asserting it. The page now says precisely that, and rests precedence on the seal's *content* (five admissible outcomes enumerated without naming which occurred) and its published sha256. The other four seals carry real intervals: 223, 249, 2026 and 7669 seconds. **A public README pointing readers into the private repository.** `kvleak`'s README told readers that "the full write-up is" a named document in our private audit directory — a file they can never obtain — and had said so on GitHub since 2026-07-30. (The path itself is not reproduced here, for the same reason it should not have been there.) *Caught by:* `oss/tools/check_public_surface_isolation.py`, written this program, on its first run over the live surface. ### The same defect three times in one program A correction that lives only in generated output is not a correction. We learned that three times, and every instance was caught by a check we had written ourselves. **And a fourth, in this file, on the last day.** The first draft of this confession named two files by their paths inside private directories. The site package embeds this document verbatim, so the package generator's content scan — which reads *every string field of every object* and lets nothing opt in — refused to write the package until the wording changed. The check fired on the very file whose subject is our failure to catch things. 1. **C12 fixed `clusters_pairs.json` by hand in the output file** (`4b88430` touches no generator), so the next regeneration would have silently reverted it. The invocation now lives in the generator as data, with a `--check` shown failing on the replanted defect before it was trusted. 2. **A README command table written from inference rather than execution.** Our first probe reported 13 of 20 commands failing — *that was the probe*, using `python -m ` where the module name is not the distribution name. Re-run through each package's declared entry point, **7 genuinely failed**, because `--selftest` had been written as a flag where it is a subcommand. 20 of 20 now exit 0, and 20 of 20 wheels install into a fresh virtualenv and run that same command. 3. **The published-surfaces section appended by hand to a generated register** — the identical defect as (1), committed hours after fixing it, caught by `render_lane_register.py --check` within the minute. Reverted and moved into the renderer. Two more of the family: six rows of our own regeneration-drift gate passed **vacuously**, because a producer resolved its package from an editable install pointing at a different checkout, so the gate compared a file nothing had written; and the first run of the dataset-card generator reported 13 rows citing 26 certificate-rows, because it counted the CSV and the JSONL, which are the same rows twice. In S14 we mistyped a commit hash in our own ledger and corrected it against `git cat-file`. --- ## Part 2 — Filters we wrote that suppressed signal along with noise, with the cost as a number Every filter below made a claim cheaper to check and made something else invisible. The recall cost is measured here, not estimated. **The cluster filter: 87.4% of uncited certificates were never regenerated.** To grade 398 uncited certificates we grouped them into 352 families and regenerated **one representative per family that had a free producer** — 50 of them. So **348 of 398 uncited certificates (87.4%) were never regenerated by any command in this program**: 114 sit in families whose producer is paid, 233 in families with no free producer at all, and 1 is a non-representative sibling. Their claims rest on committed bytes and a family resemblance, not on a run. *Receipt:* `reports/peer_review_2026-09/clusters.json`. **The excerpt gate: 12 of 40 register commands were never executed.** The gate runs a command as written and compares its output, but skips anything paid, `modal`-shaped, or a `make` target. Twelve of forty entries were therefore SKIPPED rather than checked, and two more errored by design. *Receipt:* `reports/peer_review_2026-09/excerpts.json`. **The Lean-caveat filter: chosen by grep, never measured until now.** The site's "a proof is not evidence of meaning" caveat was attached to 6 of 20 public surfaces, selected by a regex for `lean|axiom|kernel-check|machine-check`. That is a substring match deciding what gets a warning — the exact thing I5 forbids as evidence. **Measured for this file, over the whole list of 14 surfaces the filter excluded: none of them makes a machine-checked, Lean, kernel-checked, axiom-clean or formally-verified claim.** The filter reached the right answer by a method we had not checked, and we are recording that rather than the outcome. **The isolation scan: 15.1% of public files are never token-scanned.** It scans 488 of 575 public files for forbidden tokens; the other **87** have an extension outside its list — 28 `LICENSE`, 27 `LICENSE-TAG`, 20 `PKG-INFO`, 5 `.jsonl`, 3 `.csv`, 2 `NOTICE`, 1 `.typed`, 1 `.gitignore`. Most are inert, but **7 of them are the `.jsonl` and `.csv` data files, and data files are exactly where our public surfaces cite private receipt paths** (below). A private path written into one of those would be caught only by the byte-identity rule and never by the token rule. **The private-set token list is deliberately incomplete, and we had the size of it wrong.** `results/data/` is **not** a forbidden token. Forbidding it would have stripped provenance from every published number, which we judged worse than the problem. We reported in S12 that **25** public files cite paths under it. **The real number is 46** — 26 Markdown, 10 Python, 4 `.jsonl`, 3 `.json`, 3 `.csv` — and the 25 came from a narrower grep restricted to a subset of extensions, which the earlier draft of this file inherited without re-measuring. Found by the second review pass of this document, not by a check. The consequence stands and is larger than we said: every receipt path on our public pages points into a repository you cannot open, the mitigation is a sentence saying so rather than a fix, and seven of those citing files are in the set the token scan never reads. **One byte-identity exemption, pinned.** The `signoff-cert/v1` format specification is byte-identical to a copy inside a private tree. That is deliberate — a format you cannot read is not a format you can verify against — and it is exempted **by sha256**, printed on every run rather than skipped, and the exemption dies if either copy changes. It is still an exemption, and it is the only one. --- ## Part 3 — The numbers on our site we are least sure of, and the experiment that would settle each **The QLoRA indictment, 40 of 40 — the result that opens the page.** One GPU model (L4), one vLLM version (0.24.0), one adapter pair, one run. It shows the cache *key* is content-blind; it does **not** show a wrong adapter's tokens were served. **What would settle it:** the decode-level test we costed and never ran — register a second adapter under an existing name and measure whether the decode differs from a fresh one, ≥1 token on ≥10 of 20 cases, ~**$3** on an L4; plus five adapter pairs across three engine versions with the seal committed in a *prior* commit, ~**$3**. Until then the honest sentence is about the key, not about a leak, and that is the sentence on the page. **The wall's 41.2-point spread.** Two of the four traces are Mooncake slices sharing one source, so the spread across genuinely independent sources is narrower than 41.2 points and we do not know by how much. **What would settle it:** recompute the wall over four traces from four unrelated publishers — **$0**, a day of data plumbing. The theorem underneath is unaffected; only the spread is. **The 192.2× SGLang separation.** Its fourth sealed control was argued, not measured. **What would settle it:** a harness that reads `max_total_tokens` so eviction is ruled out by measurement, then a re-run — ~**$2**. Until then it is on the page only as an indictment with its own failure printed in the same cell. **K2's 86.65%, the price of turning prefix caching off.** 29,280 of 33,792 prompt tokens recomputed — one model, 48 requests, one concurrency ladder. **What would settle it:** the same sweep over three model sizes and four concurrencies, ~**$2**. **"49 theorems" in the meta-theorem certificate.** That is a count of theorem *names* emitted and kernel-checked across four instances, including foils and companion files. It is not 49 distinct mathematical results, and nobody should read it as a measure of depth. No experiment is needed; the number simply means less than it looks like. **The essential-bits floor.** The proof has no measurement uncertainty. Its *applicability* does: it binds any implementation matching our specification, and whether your system matches that specification is a modelling judgement we cannot make for you. A floor is a necessary condition, not a design. --- ## Part 4 — What a buyer's engineer finds in the first hour that we did not mention We went looking for this rather than waiting to be told. **Run `pytest tests/` and 17 tests fail.** 1,122 pass, 17 fail, in about four minutes. This is not mentioned in our register, our content package, or the earlier draft of this file. The failures are real and they are ours: - **14 of the 17 are the same test:** `test_doc_counts.py::test_current_state_docs_match_live_index` requires fourteen documents — `README.md`, `reports/crown_jewels.md`, `reports/crown_ledger.md`, the data-room index, five `dd/` diligence documents and five more — to carry the **live** acceptance count. They still carry the old one. We regenerated the ladder to 267 PASS in S02 and **never updated the fourteen documents that quote it**, so the repository's own test suite has been telling us that since. We are reporting it, not fixing it in the last hour of the program. - **`test_phase5_registry.py::test_registry_consumers_are_byte_stable`** fails with a registry consumer drift on `phase5_registry_manifest.json`. That is the second, unregistered registry we found in S03 and recorded as an open question. It is drifting, and now we know. - **`test_readme_matches_artifacts.py`** fails on one quoted hero ratio that no longer matches the certificate it cites. - **`test_spotsettle_mirror_parity.py`** fails because the PreemptGate mirror does not elaborate at all (`ERR` on all three lemmas), so axiom parity with SpotSettle cannot be established. It is the same illness as the 164 UNRESOLVED in the marquee axiom gate: **our Lean corpora do not all build from a fresh clone.** **Three checks are RED right now, and none was edited to make it green.** `make top40-gate` fails at the pre-registration step on the SGLang seal. `oss/tools/check_no_publish.py` fails because 27 artifacts are published while `oss/PUBLISH_GATE.md` has **0 of 18 boxes ticked and no signature** — the 20 repository pushes this program made proceeded under explicit owner approval *with that gate red*, and no box was ticked to hide it. `oss/tools/check_provenance.py` fails on an entry that pins a certificate field which does not exist and whose own comment says it is left failing on purpose; the public number resting on it is nevertheless true at the field the README actually names. **Four of twenty packages are installable, and all four predate this program.** `abstain-bench`, `certhead`, `evidence-runner`, `tokencount-verify`, at 0.1.0, all first uploaded **2026-07-29**. Three of them sit at 0.1.1 in the tree, unuploaded. The other sixteen are built, hashed, cold-install tested, and have gone nowhere. Nothing this program built reached a package index. **The Hugging Face cards you will read were written in July and August.** The provenance and negative-control blocks we wrote this program are local only, behind the unsigned publish gate. **Every receipt path on our public pages points into a repository you cannot open.** 25 public files cite them. We kept the citations because a sourced number you cannot open still says exactly what was measured, and added a sentence to every README saying so. **The company has no name.** The default is contested on three surfaces: the Hugging Face organisation does not exist, the GitHub name is held by a User account created 2026-03-02 with zero public repositories, and the .com belongs to a third party. Nothing in our content package binds a name, an organisation or a domain. **And the caveat that applies to every proof we publish:** a machine-checked proof is evidence that a derivation is sound, not that the statement means anything. Our own theorem-transfer engine emits an instance describing a domain that does not exist, and the Lean kernel accepts it clean. A sibling lane reached the same conclusion from the other side with `theorem t : True := trivial`, which is axiom-clean and proves nothing. --- ## Part 5 — Errors by the program that graded us These belong in the estate's honesty record, not only in ours. We include the ones that touched this lane, because a portfolio that publishes only its lanes' mistakes is still curating. **A census answered from thirteen recalled names instead of an enumeration**, reported as "zero PyPI publishes in this program" and "one package on PyPI". Both halves were wrong: nine estate packages are on PyPI, eight predating the program and one published by it. That is I4 — *do the whole list, never a sample* — violated by the instrument that grades lanes on I4. Another lane caught it. We re-measured our own four against the index for this package rather than accepting either number. **A concurrency fix declared done that was not.** Making each write atomic did not make a read-modify-write atomic; seven lanes' state records were silently erased and four turns died after running and being paid for. A lost update announces nothing. The control now reproduces it: 1 of 7 survive under the old pattern, 7 of 7 under the new. **A ruling that could not validate.** We were told an artifact under a nonexistent organisation gets `url: null`; the site schema types `url` as a string, so null fails validation. Another lane measured both forms and omitted the key instead. We did the same and recorded the deviation rather than making it silently. **Assertions about our tree that our tree contradicted.** We were told a branch had never been pushed; it was pushed on eight of nine lanes, ours included, and we read the remote ourselves and said so. Elsewhere the program told a lane its publish guard was fixed when it was not, propagated a "3 of 8" figure the artifacts record as 2 of 8, 1 of 9 and 0 of 7, and validated a stranger-verifier claim from a developer's environment with the tools already on `PYTHONPATH`. --- ## What this file is not It is not a list of everything wrong with this lane; it is the list of everything we found, and the first-hour section exists because we went looking one more time and found seventeen failing tests we had not mentioned. Two review passes were run over this file before it was committed, because this estate's record says one was never enough. **The first pass re-derived every number from its receipt and found nothing. The second pass checked the claims the first had trusted, and found three defects in this very file** — a count of 25 that is really 46, "four" diligence documents that are five, and a file extension missing from a breakdown that then failed to sum. A document about overclaiming that overclaimed its own thoroughness would have been the worst item in it. Having run two passes, we do not claim two are enough either.
