03 / ECONOMIC NARRATIVE

Economic identity

Observed sponsorship, authorization, scope, transfer, and outcome. No estimates or inferred value.

01 / MANDATE
Sponsored and authorized
The recorded mandate names both its sponsor and initiative, with authorization tied to a named approver and approval time.
SPONSORNorthset OSS Fund · OSS mission experimentation
AUTHORIZEDinternal-user:aeziz · 2026-07-16T17:14:22.601Z
02 / WORK
Demand became scoped work
An external issue invitation became a stable task and a recorded code-and-test scope, without treating scope as a measure of value.

INVITATIONIssue #971 · label
SCOPE5 files · 61 changed lines · 4 production files · 1 test files · 3 declared checks
03 / EXTERNAL OUTCOME
Transfer and upstream state
The recorded maintainer transfer and its contingency are separate from upstream state, which remains a mutable external observation.
MAINTAINER TRANSFERnone · not merge contingent
UPSTREAMOPEN · mutable external observation

04 / COST COMPLETENESS

Known, unknown, and unpriced

Known: maintainer payment was none. A known zero external transfer is not a zero total cost.

PASS — 3/3 declared commands

Every command listed returned exit 0 in the declared environment. Only the listed commands are in scope. Unlisted test, lint, typecheck, build, coverage, compiler, full-suite, and CI gates are not implied or recorded.

Public scope interpretation

The receipt proves the declared automated checks only; maintainer review and merge remain independent human decisions.
