#Capabilities

Overview

Tenant-scoped, atomic receipt stores for @absolutejs/agent-exchange-secure-messaging. The package provides memory, Redis, and PostgreSQL implementations behind the same receipt-store contract.

The tenant is bound when a store is constructed; callers cannot select a tenant per operation. Tenant and exchange identifiers are SHA-256 digested before use in keys. Receipts are strictly parsed, size bounded, expiration aware, and compared as canonical JSON. Saving an identical receipt and expiry returns duplicate; any different receipt or expiry for that live key returns conflict.

Redis adapter

Implement get(key) and eval(script, keys, arguments_) with the official client of your choice. The exported Lua script performs compare-or-insert and absolute expiration (PXAT) as one Redis operation. Do not replace it with a client-side GET followed by SET.

PostgreSQL adapter and migration

Run AGENT_EXCHANGE_RECEIPT_POSTGRES_MIGRATION through your normal migration system before constructing the store. The same idempotent SQL ships at the exported ./migrations/postgres.sql package subpath for migration tools. Pass a client with a parameterized query(text, values) method. Save uses one INSERT ... ON CONFLICT ... RETURNING statement, including a random per-attempt token, to distinguish a new write from duplicate and conflicting concurrent writes without a read/write race.

Call deleteExpired({ now }) from a repeatable maintenance job until it returns zero. It deletes at most 1,000 rows per call by default; batchSize is bounded to 10,000. Redis expiry is automatic.

The memory store is process-local and intended for tests and examples only.

Outcomes

What you can build

Build on the supported package contract

Use @absolutejs/agent-exchange-secure-messaging-stores through its supported public entry points.

Hardening checklist

Production guidance

Make every external boundary explicitPin the deployed @absolutejs/agent-exchange-secure-messaging-stores version, replace example or memory-backed dependencies with durable implementations, bound external calls, protect credentials, and emit enough evidence to retry or recover safely.

Troubleshooting path

Trace from the first failed boundary
Reproduce the smallest canonical @absolutejs/agent-exchange-secure-messaging-stores example, confirm the supported entry point and version in the API explorer, then inspect the first boundary that did not produce its documented result.
