# grantConsent

mutation · in the family [Selling](/reference/selling/)

## What it does

Record a customer’s consent (marketing, data use) as staff, on their word.

STAFF: record a GRANT decision for a NAMED consumer: NO record → DUAL-BIRTH born granted (the PERMANENT pair marker + the FIRST-decide everReferenced stamp ride the ONE transaction) · withdrawn → the evented transition (capture context REFRESHED) · already granted → a capture-context REVISION (re-consent under a new policyVersion — never an FSM self-loop). Gates: purpose ACTIVE + consumer NOT doomed (each CONFLICT/REF_STATE naming it; a SUSPENDED consumer stays LEGAL — the subject's right). The create race self-cures via the marker. Requires the unrestricted capability. Template class (capture-at-source — hand-derived v20).

## Careful

Consent records are legal facts — record only what was actually given.

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `input` | [ConsentDecisionInput](/types/ConsentDecisionInput/) `ConsentDecisionInput!` | yes | No further notes. |

## Returns

[ConsentRecord](/types/ConsentRecord/) `ConsentRecord!` — A ConsentRecord — the PROOF-OF-DECISION per (Consumer × Purpose): CONSUMER-parented (parentId = the Consumer id — the LoyaltyMember construct-parented class), family document, SPARSE (a record materializes ONLY on an explicit decision — the ratified DUAL BIRTH: born directly granted on a grant, withdrawn on a withdraw \[ruling 4 — an explicit 'no' is proof-of-refusal on EITHER model]). The PERMANENT (consumer × purpose) UNIQ pair marker is BOTH the singleton guarantee AND the O(1) lookup (never released, never taken over; purge reaps). FSM: granted ⇄ withdrawn (bidirectional forever — GDPR Art. 7(3), withdrawal as easy as granting) → doomed ONLY via system:consumer_erased. NO update op — the ONLY writes are the 4 decide ops (grantConsent/withdrawConsent staff · grantMyConsent/withdrawMyConsent consumer) + the system doom; a SAME-decision re-capture is a capture-context REVISION under a new policyVersion (re-consent — route 3; revisions keep every prior capture, the Art. 7(1) proof). Capture context ∈ {policyVersion, captureSurface ∈ \[storefront, pos, back_office, cli, import], captureLocale?} reflects the LATEST decision. Effective consent = resolveEffectiveConsent (the myConsents view): consumer doomed ⇒ DENIED · purpose inactive/doomed ⇒ DENIED · granted ⇒ ALLOWED · withdrawn/doomed ⇒ DENIED · ABSENT ⇒ opt_in? DENIED: ALLOWED. AUDIT RIDES EXISTING MACHINERY — NO bespoke ledger. NOT searchable (PII-bearing proof — the stance).
