Beta.14 arrival family square-oauth-application-secret (#583, product redact-secret#1107), contract in benchmarks/lib/beta8/583a.ts from the #1014 handoff square.md. T1 by example under R5 (the 43 or 44 union follows the Polar era-union precedent), conditional on Q8. Shares the square-token detector (finding type square_oauth_application_secret), so it is an arrival family scored by that finding type (scanners/families.mjs arrivalFindingTypes).

New pipelineAuthority

Built from the new pipeline

The new pipeline is the authority for credential qualification. These numbers are read from the qualification view derived from the official credential-eval run of the public-evidence-snapshot population. The regression and policy populations keep their own counts on the qualification pages and are not added in here.

Authority: new
Population: public-evidence-snapshot
Engine: credential-eval 0.1.0-alpha.16
Evidence: snapshot-2026.10.06.4

Maintainer-reviewed (independent review pending)

598 fixtures of the 7,041 in evidence release snapshot-2026.10.06.4 carry this label. They are counted in the numbers on this page.

Passed the project’s own verification (source evidence, automated checks, recorded counter-arguments); not yet independently reviewed.

OpenRedaction default (all patterns): not measured in this run (optional)

The default (all-pattern) profile is slow and noisy for credential evaluation: personal data and resource identifiers dominate its findings, and its last official measurement took 7 minutes of scanner time on a population the credential profile scans in seconds (its methods run takes 40+ minutes), so it is a manual measurement and never blocks other scanners or core verification (#763). Its earlier results stay as history with their run identity; the credential profile is a separate scanner, never spliced with it.

Last measurement: policy-corpus@linux-x64 (configuration sha256:2451ce7bf380), public-evidence-snapshot+methods@linux-x64 (configuration sha256:d47d081ce5fb), public-evidence-snapshot@linux-x64 (configuration sha256:2451ce7bf380), regression-corpus@linux-x64 (configuration sha256:2451ce7bf380) · engine 0.1.0-alpha.5 · recorded 2026-10-05 · retained record, no longer listed by the run registry. It stays labelled with that run identity and is never combined with another profile or another run.

OpenRedaction credential profile (33 types): not measured in an official run (local exploratory diagnostics only: see ADR)

The credential profile is the comparison profile chosen in docs/decisions/2026-10-06-choose-the-openredaction-credential-bearing-profile-as-the-comparison-scanner.md. It is optional in the official run class because no pinned engine configuration measures it yet: making it required would refuse every official view until the owner approves the one profile-only run. Its own history starts with that run; nothing of the default's is reused for it.

No earlier measurement of it is recorded. Nothing is shown in its place.

Official measurement: pending: requires owner approval (one profile-only run; see the decision).

Benchmark dossier notes

From the provider dossier, as written. The evidence level above says how well the format is backed; a fact the dossier does not record is not shown.

Shape: sq0csp- + 43 or 44, or sandbox-sq0csb- + 43, over [A-Za-z0-9_-].
Basis: the walkthrough shows 43 (production and sandbox), the ObtainToken reference and its generated SDK fixture show 44 (R5); the union follows the Polar era-union precedent. gitleaks 8.30.1 has no sq0csp- rule; trufflehog squareapp reads 40 to 50 and also the public sq0i?? application ids.
Issuance: same check as above; it settles 43 vs 44 and whether the sandbox secret has one width.
Contract in core: the same detector, finding type square_oauth_application_secret.

Looks like it, but isn't

Values the dossier records as resembling this credential without being one.

Collisions: sq0idp-, sq0ids-, sq0idb- and sandbox-sq0idb- application ids are public by design (Q5); sq0cgb- authorization codes are short-lived.

Scanner rules for this family

Mapped by hand (reviewed 2026-09-30) from each scanner's pinned rule file, never from what a scanner found on the fixtures.

Peer scanner rules that target this family
Scanner	Rule	What the rule matches
flare-redact · rules 1.6.1	`square_token`	sq0 + three letters + - + 22-43, or EAAA + 60 [A-Za-z0-9_-]; the sq0i?? alternatives are public application ids
trufflehog · rules 3.97.4	`squareapp`	(sandbox-)sq0c?? + 40-50 [0-9A-Za-z_-]; the same detector also reads sq0i?? application ids (public identifiers)

No rule maps to this family in gitleaks, openredaction.
