Receipts

Roadmap — vision layer

The RCPT-* class taxonomy below is the planned StreetLedger event-record model (vision layer). It is distinct from the two receipt systems that ship today:

• DefendableCloud — per-org hash-chained DCR-* receipts, verifiable via /ledger and /ledger/verify. See Generate a Receipt.
• DefendableRouter — checksummed (not chained) JSONL receipts written locally per day.

Treat the schema below as design intent, not a built endpoint.

What a receipt is

A receipt is the per-event record that captures WHAT happened · WHEN · in WHAT context · with WHAT hashes. Every receipt is the input to one or more deeds.

Pattern: RCPT-{CLASS}-{YYYYMMDD}-{ULID}

Receipt classes

Class	What it records
RCPT-VOCAB-*	A vocabulary term mint
RCPT-CHAT-*	A StreetChat session event
RCPT-AWARD-*	An engagement award
RCPT-MEDIA-*	A media artifact (blog post · podcast episode)
RCPT-VALIDATION-*	A validator chain pass
RCPT-MINTING-*	A deed-issuance event

What a receipt always contains

• receipt_id · source_event_id
• Hashes of every related artifact
• Count of related extracted entities (terms · directives · risk flags · pairs)
• tribunal_classification (inherited from upstream verdict)
• issued_at · issued_by · status
