ExemptionCertificate
object type
A tax-exemption certificate — a captured legal document: a valid in-scope cert ZEROES tax at sale for its covered jurisdictions/categories (the calc consumes it; at-USE validity = status active ∧ not past expiresAt ∧ scope match — CONFLICT/EXPIRED per SPEC_ERRORS). Parent = the org group, FIXED AT BIRTH (the / customer host is a later REF, never a reparent). Capture is INLINE. The capture is IMMUTABLE except caption/code/docRef — correct anything else by revoking and re-capturing. active → expired is SCHEDULED; revoke and doom are the caller ops.
Fields
| Field | Type | Notes |
|---|---|---|
id | ID ID! | The record’s id — a UUID the platform assigned when the record was created; every reference to this record uses it. |
sysId | String String! | The group-scoped human-facing system id (XC-…). |
type | String String! | The kind of record — always ExemptionCertificate here. |
caption | String String! | The record’s display name — what people see it called. |
status | String String! | The FSM state: active | expired | revoked | doomed. |
parentId | ID ID! | The parent org group; for an ExemptionCertificate parentId === rootId. |
rootId | ID ID! | The org-group family root. |
createdAt | String String! | When the record was created, as a UTC timestamp. |
updatedAt | String String! | When the record last changed, as a UTC timestamp. |
revisionNum | Int Int! | How many times this record has been edited; the first save is 0. |
revision | ID ID! | The OCC revision token — supply it on every mutation of this record; rotates on every write. |
refCaptions | RefCaption [RefCaption!]! | The server-composed captions of this record's declared references (the referenced-caption rule) — one row per referenced id; see RefCaption. |
certType | ExemptionCertType ExemptionCertType! | The certificate kind. IMMUTABLE at capture. |
certificateNumber | String String! | The issuer's certificate number. IMMUTABLE at capture. |
holderName | String String! | The holder as captured INLINE. IMMUTABLE at capture. |
jurisdictionIds | ID [ID!]! | The covered jurisdictions — SHARED-canonical refs, each exists+ACTIVE at capture. IMMUTABLE. |
categoryIds | TaxCategory [TaxCategory!] | The covered categories — ABSENT = all categories (the blanket-cert shape). IMMUTABLE. |
expiresAt | String | Optional expiry (UTC ISO-8601) — ABSENT = non-expiring. The scheduler arms active→expired on it; the at-USE check is the calc's. IMMUTABLE. |
docRef | String | Optional document reference (a blob pointer/URI — upload machinery is NOT this slice). Editable (the paper gets scanned later). |
orgCustomerId | ID | The holder linkage: the OrgCustomer this cert belongs to. Set-time gated (in-tenant, NON-doomed); EDITABLE — re-linkable (the ONE exception to capture immutability; the capture-doc parent stays the GROUP). A NON-doomed cert blocks its holder's doom. |
code | String | Optional mutable merchant reference code; uniqueness NOT enforced. |
