| provenance:design:dns [2026/08/27 23:04] – Refresh from the corrected artefacts and add the full review log: self-review round, citations pass, figures-vs-script pass (which found the verdict() bug), external-currency pass, with every finding's accept/reject and the reason. Authored by Claude. karel.kubicek.claude | provenance:design:dns [2026/08/27 23:21] (current) – Add review pass 5 (generic). Purge the retracted pre-fix run, which had survived in four places in this log after being fixed on the page — the section now states no verdict counts of its own and records instead what three runs showed: identical 46 and no karel.kubicek.claude |

| The %%<code>%% block on the page is generated by ''scripts/build_dns_codeblock.mjs'' from ''out/dns/resolver_run.txt'', with a mechanical abridgement rule (two header lines, the ''google.com'' stanza with address lists cut after two entries, both summary blocks). It is regenerated rather than pasted, because the first draft pasted an **earlier** run's TTLs under a **later** run's timestamp — the exact failure the builder now prevents. | **Three runs, and what moved between them.** The list was run three times over about ninety minutes: twice under the original (buggy) classifier, then again after the pairwise fix, then again after the script gained TC-bit handling. ''identical'' came back **46** in every run and ''no-A-record'' **25** in every run, so ''not identical'' was **29** in every run. The split of those 29 moved — 28 disjoint and 1 same-/24 under the buggy all-at-once intersection, then 21 partial / 8 disjoint, then 19 partial / 10 disjoint — as CDN mappings churned under the measurement. That is why the page quotes **not identical** as its headline and treats the partial-versus-disjoint split as illustrative rather than as a result. It is also why this section states no verdict counts of its own: they belong in the run output below, which is regenerated from the script. |

| | ==== Self-review, round three (after applying passes 1–3) ==== |
| | |
| | ^ Found ^ Verdict ^ |
| | | The DDR tip box's **lead sentence** still said "the one paper that looked says the deployment is broken" while the rest of the box explained that the finding is contested. That is the exact pattern this site's history warns about: the careful version survives three paragraphs down, the prominent sentence loses the hedge. | Fixed. The box now leads with "what it measures is unsettled". | |
| | | The box's footnote credited "the authors' own public write-up" without that write-up having been fetched. | Fixed by fetching it. The APNIC post (Nosyk, 2 September 2025, with Duda and Korczyński) is a better source than the ACM-403 paper and gives quotable figures: //"over 321k DDR-enabled open resolvers"//, Google at 80.8%, top five at 97.4%. Five needles from it are now checked by ''external_checks_dns.sh''. The box also makes the venue point that follows: DDR work in 2025–2026 is in PoPETs, at ANRW and on an operator blog, and this corpus contains **one** of the three. | |
| | | The code-block builder pinned its example to ''google.com''; on the re-run ''google.com'' came back ''partial'' and the block would have illustrated the wrong verdict under a "disjoint" heading. | Fixed before it shipped: the builder now selects the first stanza whose verdict is ''disjoint'', and the page states that rule. | |
| | |
| | ==== Pass 4 — figures re-check, after the fixes (sonnet, re-run of pass 2) ==== |
| | |
| | The pass-2 reviewer was re-run against the corrected page and scripts, as the workflow requires for any reviewer whose findings were acted on. |
| | |
| | ^ Finding ^ Verdict ^ |
| | | **The ''NON_PAPER_FIGURES'' ledger in ''verify_dns_figures.mjs'' was stale in three places, left behind by the very fixes it was checking** — it still said "84 self-tests" (now 85), "35/35 home-grown" (now 34/34), and "28 / 75 / … / 37.3%" for the resolver run, which are the **pre-fix, retracted** verdict numbers. No check broke, because the correct values were independently present via the report; but a ledger whose entire purpose is "which artefact backs this figure" was pointing a future auditor at withdrawn ones. | **Accepted, and fixed at the root rather than patched.** The block now lists **where** each non-corpus figure comes from and never restates its value: a pointer cannot go stale, a copy always will. Two figures then failed the whole-page guard because their values were no longer duplicated anywhere — which is the guard doing its job. The ''robots.txt'' rate is now **derived by ''report_dns.mjs''** instead of being lifted from ''OVERVIEW.md'' (a file the guard does not read), and the ''dnsdb.info'' A record was **removed from the page**: it rotated from ''104.244.14.71'' to ''104.244.14.64'' between two runs an hour apart, which is a poor thing to pin on a page about resolver-dependent answers. | |
| | | **The Rapid7 guard's audit table claimed "all ten tuples were read" when the candidate regex matches 13 tuples under 11 spellings.** The missing row is IMC 2016 //Entropy/IP//, tool name ''"Forward DNS dataset"''. It is classified correctly and the family count (8 papers) is right — but the table was not exhaustive while saying it was. | **Accepted.** Reproduced against the raw extraction: 13 tuples, 11 spellings. The provenance table now has all 13 rows, marks the two rows that cover two tuples each, and the count is corrected in the fold comment, the report comment and the prose. This is the review layer catching an **overstatement of the page's own rigour**, which is exactly what the provenance page is most at risk of. | |
| | | ''verdict()'' fix confirmed correct and complete: 10/10 self-tests, and an independent re-implementation of the documented definitions reclassified all 100 names in the committed JSON with **zero mismatches** (46 / 21 / 8 / 25, 29 of 75 = 38.7%). ''one-answered'' and ''insufficient'' are reachable and simply do not occur in this run. | No change. | |
| | | Total-deadline fix confirmed: ''deadline'' is set once and ''remaining'' recomputed per iteration; a live query to a blackholed TEST-NET-1 address returned at **2.009 s** against a 2.0 s timeout with a useful error string. | No change. | |
| | | Population confirmed unmoved by all four fold edits: A=108, B=202, A∩B=66, **DNSPOP=244**. Every page figure matches a fresh script run; ''%%<file>%%'' and ''%%<code>%%'' blocks round-trip byte-for-byte; the code block's example is confirmed the first ''disjoint'' stanza in the current run. | No change. | |
| | | The ''frozen2'' snapshots no longer match the live page, because self-review round three was applied after they were taken. | Noted, not a defect: ''frozen2'' is by definition the snapshot the reviewers read, and this log records what changed after it. Flagged here so nobody later cites ''frozen2'' as canonical. | |
| | |
| | ==== Pass 5 — generic, no checklist (fable) ==== |
| | |
| | Read the ''frozen2'' snapshots. As on every other page on this site, the generic pass found the worst remaining defect and it was of the predicted kind: a claim that is true nowhere a focused pass would look, and false where two sections meet. |
| | |
| | ^ Finding ^ Verdict ^ |
| | | **The "What to report" section claimed the extraction measures "which resolver", and the provenance page says in bold that it cannot.** The page said the schema "has a field for only the first two" checklist items — //Which resolver// and //Where from// — and gave 50.8% and 42.2%. Those two rates are **vantage location** and **any named tool version**; neither measures resolver identification. A reader would have cited "42.2% of DNS papers say which resolver they used", a figure about something else, from the most prominent methods section on the page. | **Accepted; the most serious finding of this pass.** The paragraph now says outright that almost none of the checklist is measurable, that the two rates measure adjacent things, that for //which resolver// the schema has no field and a full-text probe is an upper bound on mentions — and that **this page therefore publishes no reporting rate for resolver identification, and you should distrust any page that does**. The provenance's honest sentence now surfaces on the page instead of being contradicted by it. | |
| | | **The retracted pre-fix run survived in four places in the provenance log** — "28/100", "37.3%", a repeat-stability claim crediting the published run with the //buggy// run's verdict counts (46 / 1 same-/24 / 28 disjoint), and a heading "The 28 names with disjoint answers" over a block listing eight. | **Accepted.** This is the site's own documented failure — a fix survives on the page and dies in the provenance. All four are gone, and the section now states **no verdict counts of its own**, pointing at the regenerated run output instead. In their place it records what three runs over ninety minutes actually showed: ''identical'' 46 and ''no-A-record'' 25 every time, so ''not identical'' 29 every time, while the partial/disjoint split moved 28-0 → 21-8 → 19-10 as CDN mappings churned. **That stability difference is now a finding on the page**, and the reason it quotes "not identical". | |
| | | The ''NON_PAPER_FIGURES'' ledger and the ''dnsdb.info'' IP (also raised by pass 4). | Already fixed between the frozen2 snapshot and this report; see pass 4. | |
| | | **The DoC row's "0 / 0 / 0 / 0 / 0" was asserted, not probed.** Section G had no CoAP probe. The reviewer ran one and found the claim true, but by this site's rule an "at all" claim must never come from a probe that was not run. | **Accepted.** DoC and a bare-CoAP contrast row are now in section G. The phrase "DNS over CoAP" matches **0** papers; 20 mention CoAP as the IoT protocol; a bare ''DoC'' matches 2 and both are homographs (a US government department, a table symbol). The row now says the zero is a run probe and shows its working. | |
| | | **The page never mentions IPv6, AAAA or record types, and its own instrument is silently A-only.** The opening box said 75 names "had an address at all" where it means "had an A record"; a name with only AAAA or an HTTPS RR is indistinguishable from one that does not resolve. | **Accepted — a real content gap, not just wording.** The box now says "IPv4 address"; the script's docstring states the A-only limit and why it matters; a new run takeaway gives it a paragraph; **"which record types, and which address family" is now an item on the reporting checklist**, with the corpus rates behind it (AAAA 26.6%, CNAME 30.7%, SVCB/HTTPS 3.3% of the 244 — dual-stack is the minority practice here). Section G2 of the report prints them. | |
| | | **The published script ignores the TC bit.** With EDNS0 deliberately absent, a UDP answer caps at 512 bytes; a truncated answer would have been recorded as the resolver's complete set, manufacturing ''partial'' and ''disjoint'' verdicts. The page's own checklist tells readers to report UDP-versus-TCP fallback while its instrument could not see the condition that forces it. | **Accepted.** ''parse_answers'' now reads the TC bit, ''query()'' returns it, and the per-resolver line prints ''TRUNCATED (TC set, answer incomplete)''. The docstring explains why the script flags rather than retries. Zero truncations in the published run — but that is now a measured zero. The checklist item gained the TC question and the corpus rate (9.0% of the 244 mention truncation or TCP fallback at all). | |
| | | ''build_query()'' sat outside the ''try'' in ''query()'', so an unencodable name raised despite the docstring's "never raises" contract. | Accepted, moved inside, tested with an IDN. | |
| | | Cloudflare's 12.4% was quoted from the APNIC post but was not among the needles the external check verifies. | Accepted; it is now the fifth of six APNIC needles and passes. | |
| | | Files table said ''verify_dns_figures.mjs'' checks 29 needles; it checks 31. | Accepted, corrected, and the row now describes the pypdf fallback and the pointer-not-value ledger. | |
| | | The ethics lead explained the pattern as "no human subjects", above the page's own table showing 16 interview-or-survey and 11 user-study papers in the population. | Accepted. Softened to a plausible reading with the counter-evidence named in the same sentence. | |
| | | Scope note said "5,859 papers with extracted full text" against the methodology section's "4 of 5,859 have none". | Accepted; the note now gives 5,855 readable and says the 4 count as negatives. | |
| | | Spamhaus was named in the passive-DNS table with an em-dash instead of a count; it is not a fold family. | Accepted; removed from the row and its home in the 8-paper "other feeds" row is stated. | |
| | | "15 of them say so in the title" — the report says title **or slug**. | Accepted, corrected. | |
| | | The review snapshots are now three generations deep (passes 1–3 read frozen1, pass 5 read frozen2, live is neither), so "the reviewers read the same frozen snapshot" is no longer literally true. | **Accepted as a process finding.** The log's snapshot paragraph names which pass read which snapshot, and every change made between them is in this log. Not re-frozen a third time: another round of review is not planned, and a snapshot nobody reads is not worth the claim. | |
| | | A parked/sentinel A record (''domaincontrol.com'' → 127.0.0.1 from all three) counts as "identical" agreement. | **Rejected as a page change, recorded as a limit.** It is true and mildly interesting, but the script measures whether resolvers agree, not whether the answer is useful, and adding sentinel detection would be a different tool. Noted here so the next person does not rediscover it as a bug. | |
