Working log for algorithm_audits. Every figure on that page has its query here, with the population it is a share of. Corpus-level caveats — venue scope, the selection funnel, provisional years — are on corpus and are not restated.

Run: 2026-09-11. Corpus at the time: data/extract/run1/extractions.jsonl, 5,859 papers, 7 venues (CCS, IMC, NDSS, PETS, USENIX Security, TheWebConf, IEEE S&P), 2010–2026; 5,855 of them have full text on disk. Model: Claude Opus 5 for the run, four review sub-agents (three sonnet, one fable) — findings logged at the foot of this page.

The task brief flagged this as the smallest of five page proposals and asked for it to be sized before writing. It was. The sizing result and the decision:

Decision: created as a new page, design:algorithm_audits, linked from Design and from Automated measurements.

Written before any table, and encoded in scripts/algorithm_audits_set.mjs rather than in prose. A paper is in if all three hold:

1. (T) Treatment. It deliberately varies a property of the measuring identity or request — profile history, declared attribute, location, device, opt-out setting, ad creative — and holds the rest fixed.
2. (O) Outcome. What it measures is the platform's own response: ads served, results ranked, prices quoted, feed or recommendation contents, or an access decision.
3. (C) Contrast. The result is a difference (or a bounded absence of difference) between arms, not a prevalence over a crawl of many sites.

Deliberate consequences of this rule, each of which a reasonable person could have decided the other way:

• Attack and defence papers are in if they run the arms. [1Meng, Wei; Xing, Xinyu; Sheth, Anmol; Weinsberg, Udi; Lee, Wenke (2014): "Your Online Interests: Pwned! A Pollution Attack Against Targeted Advertising", in: Proceedings of the ACM SIGSAC Conference on Computer and Communications Security. (DOI)], [2Kim, I Luk; Wang, Weihang; Kwon, Yonghwi; Zheng, Yunhui; Aafer, Yousra; Meng, Weijie; Zhang, Xiangyu (2018): "AdBudgetKiller: Online Advertising Budget Draining Attack", in: Proceedings of the ACM Web Conference. (DOI)] and [3Zhang, Jiang; Psounis, Konstantinos; Haroon, Muhammad; Shafiq, Zubair (2022): "HARPO: Learning to Subvert Online Behavioral Advertising", in: Proceedings of the Network and Distributed System Security Symposium. (Link)] are not audit studies — they are an attack, an attack and a defence — but each runs a differential experiment against a live ad platform, and a student reading this page wants those designs. The criterion is the measurement design, not the paper's contribution type.
• Instrument papers are in. [4Lécuyer, Mathias; Spahn, Riley; Spiliopolous, Yannis; Chaintreau, Augustin; Geambasu, Roxana; Hsu, Daniel J. (2015): "Sunlight: Fine-grained Targeting Detection at Scale with Statistical Confidence", in: Proceedings of the ACM SIGSAC Conference on Computer and Communications Security. (DOI)] and [5Datta, Amit; Tschantz, Michael Carl; Datta, Anupam (2015): "Automated Experiments on Ad Privacy Settings", in: Proceedings on Privacy Enhancing Technologies. (DOI)] contribute tooling; they are the two papers the page most wants read.
• Observational “audits” are out. [6Silva, Márcio; Oliveira, Lucas Santos de; Andreou, Athanasios; Melo, Pedro Olmo Stancioli Vaz de; Goga, Oana; Benevenuto, Fabrício (2020): "Facebook Ads Monitor: An Independent Auditing System for Political Ads on Facebook", in: Proceedings of the ACM Web Conference. (DOI)] calls itself “An Independent Auditing System” and collects ads from volunteers. It fails (C). So does [7Ali, Muhammad; Goetzen, Angelica; Mislove, Alan; Redmiles, Elissa M.; Sapiezynski, Piotr (2023): "Problematic Advertising and its Disparate Exposure on Facebook", in: Proceedings of the USENIX Security Symposium. (Link)] and so does Auditing the Partisanship of Google Search Snippets (TheWebConf 2019), which audits snippets against the pages they summarise with no identity treatment at all.
• ML fairness, DP and system-log auditing are out. They share the word and nothing else.
• RCTs whose treatment is not applied to the platform are out. [8Lone, Qasim; Frik, Alisa; Luckie, Matthew; Korczyński, Maciej; van Eeten, Michel; Gañán, Carlos (2022): "Deployment of Source Address Validation by Network Operators: A Randomized Control Trial", in: Proceedings of the IEEE Symposium on Security and Privacy. (DOI)] is a randomised controlled trial, but the treatment is a notification sent to network operators; the outcome is not platform output.

No single regex finds this literature: the five vocabularies barely overlap and three of them (“audit”, “persona”, “personalisation”) are dominated by other meanings. The candidate set is the union of six probes, and each entry records which probe caught it.

Probe 7 is the one that mattered, and what it says is about the scoring, not the probes. After probes 1–6 the set had a hole at 2020–2021 and I did not trust it. Running the density probe over those years surfaced [9Cook, John; Nithyanand, Rishab; Shafiq, Zubair (2020): "Inferring Tracker-Advertiser Relationships in the Online Advertising Ecosystem using Header Bidding", in: Proceedings on Privacy Enhancing Technologies. (DOI)] and [10Agarwal, Pushkal; Joglekar, Sagar; Papadopoulos, Panagiotis; Sastry, Nishanth; Kourtellis, Nicolas (2020): "Stop tracking me Bro! Differential Tracking of User Demographics on Hyper-Partisan Websites", in: Proceedings of the ACM Web Conference. (DOI)], and run corpus-wide it surfaced [11Iqbal, Hassan; Khan, Usman Mahmood; Khan, Hassan Ali; Shahzad, Muhammad (2022): "Left or Right: A Peek into the Political Biases in Email Spam Filtering Algorithms During US Election 2020", in: Proceedings of the ACM Web Conference. (DOI)] (102 email accounts on Gmail, Outlook and Yahoo — a design no “personalisation” or “persona” probe reaches, because the paper's vocabulary is spam filtering). Three of the final 32, or 9.4%.

All three were in fact already inside the 461-paper union, caught by probe 2. What lost them was the shortlist score cut-off: candidates were ranked (_aa_short.mjs) and only those scoring ≥3 were read, and all three scored below 3. So the honest lesson is not “add a seventh probe” — it is that a scoring heuristic laid over a candidate set is a second, invisible filter, and it discarded 9.4% of the final population before anything was read.

That is why the dropped tail was re-swept rather than left alone; see Recall repair below.

What no probe reached. The inclusion rule needs a paper's design, and design language is not a vocabulary. A paper that ran arms and described them only as “Group A and Group B” would be invisible to all seven probes. No claim on the page depends on the 32 being exhaustive; the page says so.

108 candidates scored ≥3 across the probes were shortlisted with their abstracts (_aa_short.mjs). The 58 scoring ≥4, plus 17 lower-scored papers flagged by hand, were passed through _aa_adj.mjs, which prints every sentence in the paper matching an arm/treatment/control/persona pattern. Each verdict was then made by reading those sentences, and where they were ambiguous, by grepping the paper's methods section directly.

Every verdict, with the sentence that settled it, is in the script output below (–list). The script refuses to run if any entry lacks an adjudication note.

The most important finding about this page's own evidence base.

The extraction's selection screen labels each abstract securityMeasurement and privacyMeasurement and keeps a paper if either is true. An algorithm audit is frequently neither — a search-personalisation or price-discrimination study reads as fairness, economics or information retrieval.

The script asserts that these buckets sum, and that seven named papers are still found by the query — so a corpus refresh that quietly re-admits them will fail the run rather than leave a stale claim on the page.

Verified individually against labels.jsonl:

The full list of 48 is in the –list output below. Consequence, stated on the content page: every audit count on it is a lower bound, biased against fairness-framed work, and the page publishes no estimate of the wider literature's size.

Almost nothing on this page needs folding, because almost nothing on it is a free-text aggregate — the population is hand-keyed and the rest are enum-backed counts. Two exceptions:

• statistics.method is free text and ~20% stable run-to-run. It is folded to an alphanumeric skeleton (lowercase, non-alphanumerics stripped) and paper-counted, and it is published as a ranking, not as percentages. The fold does not merge synonyms: Holm-Bonferroni correction (3), Holm-Bonferroni (1) and Holm-Bonferroni method (1) are three rows in the raw output. An unfolded reading would publish “Holm–Bonferroni 3”; the true paper count for the Holm–Bonferroni family is 5 of 32, and for any Bonferroni-family correction 7 of 32. The report script now prints the hand-folded family counts alongside the raw skeleton ranking, so the page quotes a number the script produced rather than one assembled in prose. Both are in the output below.
• The eight noise-baseline phrasings are not a fold but a deliberately widened probe (_aa_noise.mjs): the narrow term “A/A test” returns 2 papers corpus-wide, so seven further phrasings were added. The count rose from 0 to 11 of 32. Residue is not applicable — the probe reports term presence, and the page states explicitly that a paper can build a null without any of the eight phrasings.

Residue of the candidate probes. Probe 2 returned 190 candidates. 27 of the final 32 audits and 5 of the 12 rejections lie inside it — the other 5 and 7 were caught by probes 4–7 — leaving a residue of 158 papers dropped at title-and-abstract level without an individual note. The union across all seven probes is 461, of which 44 were adjudicated in depth, so 417 rest on a title-level read. That is the honest residue of this page.

Two sweeps were run after the population was settled, because the probe-7 result above showed the scoring had silently discarded 9.4% of it.

1. The dropped tail of probe 2. scripts/_aa_residue.mjs takes the 158 probe-2 candidates that were never adjudicated and re-scores them with the apparatus-density probe that recovered the three late finds, at a lower threshold and requiring an outcome term. 34 of the 158 clear it. All 34 were read at title level; none is a differential platform audit. They fall into three groups: user-study randomised trials where the treatment is applied to a person and the outcome is that person's behaviour (phishing warnings, Tor nudges, consent dialogs, personalised cookie banners), platform-side A/B tests run with the platform rather than against it (How Intention Informed Recommendations Modulate Choices, Reducing Symbiosis Bias through Better A/B Tests), and passing mentions. Output below.

2. The five zero-years. The audit set has no papers in 2011, 2012, 2013, 2017 or 2021. _aa_gap.mjs requires ≥4 apparatus matches, which is too strict to prove a negative — it returns nothing at all for 2017, so a zero from it is uninformative. scripts/_aa_zeroyears.mjs drops the threshold to ≥2 and requires no outcome term, and refuses to run if any year it is given is not actually a zero-year. Over 1,002 papers in those five years it finds 2 with ≥2 apparatus terms: An Army of Me (TheWebConf 2017), which is an observational study of sockpuppets other people created, and Spotting fake reviewer groups in consumer reviews (TheWebConf 2012), which is not an audit either. The zero-years are real in this corpus — which is a different claim from their being real in the field, since 2013 is the year of Hannak et al. and the screen dropped it.

An earlier version of this log said probe 7 had been re-run on 2017 and 2021 and “returned nothing but the observational sockpuppet study”. That was wrong: _aa_gap.mjs 2017 returns nothing at all and _aa_gap.mjs 2021 returns four unrelated papers. The sockpuppet result came from a different, looser ad-hoc probe that was never committed. It is committed now, as _aa_zeroyears.mjs, and the claim above is what it actually prints.

scripts/quotecheck_algorithm_audits.mjs verifies every quoted fragment on the content page against the paper's own text, in three modes (whitespace-collapsed exact; hyphen- and quote-normalised; longest 8-word run), against both paper.cols.txt and paper.norm.txt. It exits non-zero on any failure.

28 quotes, 0 failures, all matching exactly in paper.cols.txt. Full output below.

Two quotes were caught and removed before publication, both column-splice artefacts:

• [12Guha, Saikat; Cheng, Bin; Francis, Paul (2010): "Challenges in measuring online advertising systems", in: Proceedings of the ACM Internet Measurement Conference. (DOI)]: the sentence naming the two seeded interest sets reads, in both renderings, “C was Even with static DNS entries, we sometimes (but not al- seeded with long-term interests in 'Autos & Vehicles', while ways) observed discrepancies…” — two columns interleaved. The contiguous fragment “enabled, but are seeded with different user personae” is used instead, and no quote naming the two interest sets is published.
• [9Cook, John; Nithyanand, Rishab; Shafiq, Zubair (2020): "Inferring Tracker-Advertiser Relationships in the Online Advertising Ecosystem using Header Bidding", in: Proceedings on Privacy Enhancing Technologies. (DOI)]: this PDF is interleaved throughout in both cols and norm. “we first selectively expose a” is followed by text from the adjacent column. No verbatim quote from this paper is published anywhere on either page; its contribution is described instead.

That is the page's one unfixable data-quality problem and it is why the checker tries two renderings rather than one.

Deliberately few. This page's subject is a research method, not a product, so there is no vendor documentation to verify and no version numbers to date.

• The size of this literature. The corpus cannot give it; see The screening loss. Closing it needs a pass over FAccT, EuroS&P and the IR venues, which is out of scope for a corpus-backed page.
• Whether the 146 dropped probe-2 candidates contain any true audits. They were read at title-and-abstract level only. A full-text read of all 146 would settle it and was not done.
• Whether papers build a null without naming it. The eight-term probe is a lower bound. Establishing the real rate needs 32 methods sections read for the concept, which is a different and slower exercise than the verdict read that produced the population.
• Effect sizes. Every audit measures a different outcome on a different platform with a different metric. Nothing is poolable, and the page publishes no cross-paper effect size deliberately.
• Whether sharing an egress IP across arms actually biases an ad-targeting outcome. No paper in the corpus measures it. Filed as an Open Question on the content page rather than asserted.
• The 2011–2013 and 2017 and 2021 zeros. They are real in this corpus. Whether they are real in the field is exactly the question the screening loss prevents answering — 2013 is the year of Hannak et al., which the screen dropped.

1. A new page, not a section. Reasoning in the first table above.
2. Hand-adjudicated population rather than a regex population. A regex set would be reproducible and wrong: the tight probe (27 papers) includes an inaudible-voice-command attack and a NIST privacy-framework paper, and misses AdFisher. Hand verdicts are recorded with their evidence sentence and the script refuses to run without them.
3. Attack and defence papers counted as audits. See The inclusion rule. Counting only audit studies would give 26 rather than 32 and would exclude the pollution attack, which is one of the clearest illustrations of a blank-vs-trained-profile contrast in the corpus.
4. “Price discrimination is dormant” was drafted and then withdrawn. The first draft said the last price-outcome audit was [13Chen, Le; Mislove, Alan; Wilson, Christo (2015): "Peeking Beneath the Hood of Uber", in: Proceedings of the ACM Internet Measurement Conference. (DOI)] (2015). Checking the post-2015 price discrimination/price steering hits found [14Becerril-Arreola, Rafael (2023): "A Method to Assess and Explain Disparate Impact in Online Retailing", in: Proceedings of the ACM Web Conference. (DOI)], whose outcomes are “price, recommendations, and delivery fees”. The row now reads “rare, not dormant”, with 2 of 32 measuring a price.
5. The A/A-test claim is stated as a **term count plus an eight-way concept probe, never as “nobody does this”. The distinction is load-bearing: the corpus can prove the vocabulary is absent, and can only lower-bound the practice. - **design:platforms reports 26 for “sock puppet” corpus-wide and 14 within its own platform-study population. This page reports the same 26. Both are correct; the page says so explicitly rather than letting a reader find two numbers.
6. The crawl-config reporting rows were re-based mid-run. They first compared 32 audits (8 with no crawl configuration) against 1,120 crawled papers (40 with none). On that mismatched denominator the interaction-depth row read 65.6% against 75.1% — audits worse than the baseline. Restricted to papers that have a configuration on both sides it is 87.5% against 77.9%: the sign flips. The report script now prints both framings and the page uses the shared one. This was found by my own check, not by a reviewer, and it is the exact failure the site's own house rule about denominators exists to prevent.
7. No ~~DISCUSSION~~ block on this provenance page. Comments belong on the content page. This is the default recorded for provenance: pages and it is followed here.

Four reviewers, all told explicitly that the author's context may not be exhaustive, and all handed the page text, the scripts, their outputs and these notes. The three focused passes ran in parallel first; the generic pass ran afterwards, on the corrected text.

Re-ran all four scripts (outputs byte-identical to the committed ones), re-derived every candidate count from the five probe scripts, and mutation-tested the contracts.

Checked all 12 new keys against data/corpus2/.meta or Crossref, ran a DOI-and-title dedup scan over all ~993 bibliography entries, re-grepped the quotes independently of the checker, and verified every prose attribution.

Fetched rather than recalled, as of 2026-09-11.

## What audit papers report, vs the comparable corpus baseline
   Each row states both populations. The baseline is the population named,
   not "all papers", so the two cells are comparable.

## The crawl-config rows again, on a SHARED denominator
   The rows above compare 32 audits (8 of which have no crawl config) against
   1,120 crawled papers (40 of which have none). A field that can only be stated
   on a paper that HAS a config must be counted over papers that have one, or the
   two cells are not comparable. Both framings are printed; the page uses this one.

## What audit papers report, vs the comparable corpus baseline
   Each row states both populations. The baseline is the population named,
   not "all papers", so the two cells are comparable.

## The crawl-config rows again, on a SHARED denominator
   The rows above compare 32 audits (8 of which have no crawl config) against
   1,120 crawled papers (40 of which have none). A field that can only be stated
   on a paper that HAS a config must be counted over papers that have one, or the
   two cells are not comparable. Both framings are printed; the page uses this one.
