 All **65** evidence quotes attached to an OpenWPM ''tools[]'' tuple anywhere in the corpus were checked, twice, by two different methods.
-**First pass, ''scripts/quote_check.mjs %%--tools%% "open[ -]?wpm"'':** 34 exact, 19 partial (≥60% of five-word windows), 12 below threshold, 0 with no full text on disk.

See //Quote-check refresh, 2026-09-21// at the foot of this page.
-**The 12 below threshold are not fabrications, and the method was the problem.** Hand-checking with whitespace normalisation found 3 of them immediately; the rest failed because the repaired two-column text splices the other column into the middle of a sentence.

+"Firefox v121.0" //is// in the paper; the word ''firefox'' is cut in half. A whole-quote containment test scores that quote as absent. **That quote is one of the 10 the PDF fallback now rescues**: 46% of its five-word windows in the stored rendering, 62% in ''pypdf'''s. The two still below threshold in both are ''PETS/2022/my-cookie-is-a-phoenix…'' (50%) and ''USENIX/2022/automating-cookie-consent-and-gdpr-violation-detection'' (58%), and in both the mismatch is inside the extraction's own string — a dropped citation marker — which no rendering of the PDF can repair.
 **Second pass, ''scripts/openwpm_quotecheck.py'', written for this page.** Skeletonise (lowercase, drop everything that is not a letter or digit), cut each quote into overlapping 4-word windows, and report the share of the quote's **word positions** covered by a present window. Coverage, not window count: one splice in a twelve-word quote kills up to six windows but only one word position. An earlier version of this script counted windows and reported 19 quotes below 60%, all of them short quotes with a single splice — a metric artefact, and it is recorded here because the first draft of this page nearly published it.

 The historical stale-caveat row now records that the paired ''programming:crawler'' page was fixed in this sweep. The fresh rendered DOM confirmed both ''Artifacts'' links are live; no figures or citations changed.
+===== Currency re-check, 2026-09-17 =====
+The stale illustrative release/browser sentence on [[programming:crawler:openwpm]]
+was already corrected when this item was read: the page says ''OpenWPM 0.36.0
+(Firefox 154)''. No content edit was made. The release pin and moving stable
+channel were re-fetched with these commands:
+<code>
+curl -sS 'https://product-details.mozilla.org/1.0/firefox_versions.json' | python3 -c 'import json,sys; d=json.load(sys.stdin); print(json.dumps({k:d.get(k) for k in ("LATEST_FIREFOX_VERSION","LATEST_FIREFOX_DEVEL_VERSION","FIREFOX_ESR","FIREFOX_ESR_VERSION")}, sort_keys=True))'
+curl -sS 'https://raw.githubusercontent.com/openwpm/OpenWPM/v0.35.0/environment.yaml' | rg -n -i 'firefox|geckodriver'
+curl -sS 'https://raw.githubusercontent.com/openwpm/OpenWPM/v0.35.0/scripts/install-firefox.sh' | rg -n '^(TAG|TARGET_SUFFIX)|FIREFOX_|firefox-ci|taskcluster'
+bash scripts/openwpm_firefox_availability.sh
+</code>
+Mozilla's product-details API returned ''LATEST_FIREFOX_VERSION=156.0''. The
+v0.35.0 installer returned ''FIREFOX_152_0_RELEASE'' and its environment pins
+''geckodriver=0.37.0''; the availability checker returned ''v0.35.0 ...
+FIREFOX_152_0_ .tar.xz HTTP=200'' and ''v0.36.0 ... FIREFOX_154_0_ .tar.xz
+HTTP=200''. The content page's 0.36.0/154 example therefore names that release's
+own pin, not the moving stable channel.
+===== Review layer, 2026-09-17 =====
+One shared ''model: sonnet'' external-currency pass ran after publication and
+re-ran ''bash scripts/openwpm_firefox_availability.sh''. It **passed** the
+existing ''OpenWPM 0.36.0 (Firefox 154)'' example and found no correction needed;
+the v0.35.0 and v0.36.0 pins returned HTTP 200 from their resolved Mozilla build
+URLs.
+===== Quote-check refresh, 2026-09-21 =====
+The 2026-09-04 ''cols''-vs-PDF audit on [[:provenance:literature:corpus]] showed that 73.1% of evidence quotes that cannot be located in ''paper.cols.txt'' **are** present in an independent ''pypdf'' rendering of the same ''paper.pdf''. ''scripts/quote_check.mjs'' was patched the same day to re-check everything below threshold against that second rendering and report a fourth verdict, **RESCUED**. §5's first-pass figure predates the patch. Re-run, unedited first line:
+<code>
+$ node scripts/quote_check.mjs --tools 'open[ -]?wpm' --show 400
+quotes checked: 34 exact, 19 partial (>=60% of 5-word windows), 10 rescued from the PDF, 2 below threshold in both renderings, 0 with no full text on disk.
+</code>
+^ Figure ^ Was ^ Is ^ Why ^
+| quotes checked | 65 | 65 | population unchanged — the corpus has not moved |
+| exact | 34 | 34 | unchanged |
+| partial (≥60% of 5-word windows) | 19 | 19 | unchanged |
+| rescued from the PDF | — | **10** | new verdict; these were inside the old 12 |
+| below threshold | **12** | **2** (in both renderings) | 12 = 10 + 2 exactly; nothing else moved |
+**This page argued for the fallback before the fallback existed, and the second pass is not superseded by it.** §5's ''openwpm_quotecheck.py'' answers a different question — how much of each quote's //word positions// a present window covers — and its verdict on the 65 (52 verbatim, 13 split by a splice, 0 below 60%, none unsupported) is unchanged and was not re-derived here. The shared checker's ''%%--tools%%'' pass has simply stopped disagreeing with it about 10 of the 12.
+**Scope of this edit.** §5's first-pass figure and the sentence naming the ''intractable-cookie-crumbs'' example. ''openwpm_quotecheck.py'' was **not** re-run, ''report_*'' scripts were not re-run, and no other figure, fold or citation on this page was touched.
