 | Page id | ''privacy:policies'', **not** ''privacy:privacy_policies''. Decided 2026-09-07 on [[:roadmap]] (see [[:provenance:roadmap]] §3) because ''privacy_policies'' sorts next to the site's own ''privacy_policy'' page in search. ''scripts/sitemap.mjs'' already gated on ''privacy:policies'' and the roadmap's Queued table already promised it, so any other id would have left a dangling promise |
 | Models | Page, scripts and this log: Claude (Opus 5, with the 2026-09-09 draft written by the same model in an earlier session).

 Four reviewers, all told explicitly that the author's context might not be exhaustive, and all handed the page text, every script and its unedited output. The three focused passes ran in parallel on the first revision; the generic pass ran afterwards on the corrected page and on this log.
-==== Pass 1 — figures against the script (''sonnet'') ====
+==== Pass 1 — figures against the script (sonnet) ====
 Re-ran all four scripts and diffed them against the committed outputs: **byte-identical, no drift.** Then checked every numeral on the page.

 The pass also independently re-derived a long list of figures it found correct, including the whole tool-lineage table, the per-venue table, the platform split and the probe table.
-==== Pass 2 — citations and quotes (''sonnet'') ====
+==== Pass 2 — citations and quotes (sonnet) ====
 Independently re-extracted the page's citekeys and quoted spans rather than working from a supplied list, and verified all 22 new BibTeX entries against the corpus index, the paper PDFs and the PETS landing pages.
@@ Line 202: / Line 202: @@
 It also confirmed: 34 of 34 citekeys resolve, 0 key collisions, 0 DOI or title duplicates against the live bibliography, and all 22 new entries correct in author order, venue, year and identifier — including three where the PDF's front matter splits the byline across columns and a careless reader would drop authors.
-==== Pass 3 — external currency (''sonnet'') ====
+==== Pass 3 — external currency (sonnet) ====
 Fetched rather than recalled. Its findings and their verdicts are in the //External sources// table above rather than duplicated here; in summary it **corrected** the P3P currency claim, the PoliGraph GPU claim, the APP-350 licence symmetry and the artifact-discoverability footnote, **confirmed** every dataset host, every repository date and licence, and both platform-policy quotes, and **could not verify** two things now listed under //What could not be established//.
@@ Line 208: / Line 208: @@
 One of its corrections was itself incomplete and was corrected in turn: it proposed replacing the discoverability footnote with a claim about Calpric and Lalaine, but a direct GitHub name search showed the genuinely unfindable pair is **PolicyLint and PoliCheck**, whose repository is named after neither tool. A reviewer finding is a lead, not a verdict.
-==== Pass 4 — generic (''fable'') ====
+==== Pass 4 — generic (fable) ====
 No checklist. It ran on the corrected page and on this log, and it was the most productive of the four. Its own disclosures, recorded because they matter: one of its mutation-test commands was denied, so a later ''sed'' ran against the committed ''scripts/policies_quotecheck.mjs'' instead of a copy; it reverted the change and said so. Verified independently afterwards — the script reproduces its committed output byte for byte. It also noted that the content page was edited while it read, which is true and is a process failure of mine, recorded below.
