CANONIC ("Governance Is Compilation," Dexter Hadley, arXiv:2607.05410, 10 June
2026) does not claim to have invented the "record separate from verdict" shape. The
paper opens by calling its precedents exactly that — "partial precedents that the
present work generalizes" (§1) — and the lineage is named across three separate
sections. The Related Work table (§6, Table 7) positions the system against Open
Policy Agent / HashiCorp Sentinel, C2PA, model and data cards, study
preregistration, and Anthropic's Constitutional AI; C2PA's entry reads "media
files... at capture or edit... cryptographic manifest bound to the file... capture
device or editor" as the locus of control. The GitHub-as-substrate passage (§5)
credits the platform — via git's commit graph — with "an immutability guarantee
through the append-only commit graph that records every state transition" (the
ledger itself is defined in §3 as "an append-only record, implemented here as a git
repository"). And §4 places the ledger inside a longer explicitly-named historical
sequence: **"the corresponding historical layers in computing infrastructure
accreted over decades: the Unix kernel in 1969, POSIX operating-system standards
in 1988, the iOS App Store distribution model in 2008, and Bitcoin's immutable
ledger in 2009."**

This is a distinct angle from what CANONIC *delivers* — an accountability ledger
that guarantees checkability rather than truth, covered at
[[claim-canonic-deliverable-is-an-append-only-evidence-ledger]]. The present note
isolates what CANONIC says about its own *precedents*: like ActiveGraph, it frames
its move as recombination of known immutable-record designs applied to a new problem
(AI content governance), not first invention of the append-only-record-plus-external-judgment
shape. This is the second of the two original data points behind
[[question-append-only-ledger-cross-domain-convergence]] declining to claim
independence, alongside ActiveGraph's explicit event-sourcing attribution
([[claim-activegraph-attributes-append-only-log-to-event-sourcing-cqrs]]).

Some of the precedents CANONIC groups here — C2PA, Open Policy Agent, study
preregistration — are grouped by the broad "gate at admission, verdict elsewhere"
criterion rather than the narrower append-only-log mechanism, and whether they
actually match the log criterion is left open at
[[question-c2pa-opa-preregistration-append-only-log-criterion]]. This note feeds the
synthesis at
[[claim-append-only-log-recurrence-is-event-sourcing-diffusion-not-blind-convergence]].
