GPG-encrypted password store using the pass CLI (passwordstore.org). Can return just the first line of a multiline entry (the password, by pass convention) or a named metadata field such as login. Emits OpenTelemetry spans for get, put, and list so vault reads are visible in traces, including reads during model and workflow runs where the host emits nothing. Span attributes carry the vault name, key and field names, and backend only — never secret values or error messages.

gopass password manager (gopass.pw) - pass compatible with extra features. Emits OpenTelemetry spans for get, put, and list so vault reads are visible in traces, including reads during model and workflow runs where the host emits nothing. Span attributes carry the vault name, key name, and backend only — never secret values or error messages.

Stores swamp runtime data in Valkey/Redis with sorted-set path indexing for O(log n + k) prefix lookups and SET NX distributed locking. Compatible with local Valkey, AWS ElastiCache Serverless, and AWS MemoryDB. Implements two-phase sync to minimize time under the global lock. Emits OpenTelemetry spans for Valkey commands, lock acquisition/release, and push/pull sync so datastore activity is visible in traces when a TracerProvider is configured.

Stores swamp runtime data in PostgreSQL with row-based distributed locking. Compatible with AWS RDS, Aurora, and Aurora Serverless v2. Uses fencing tokens for split-brain safety across failover events. Emits OpenTelemetry spans for SQL operations, lock acquisition/release, and push/pull sync so datastore activity is visible in traces when a TracerProvider is configured. The connection string, which embeds the password, is read from a swamp vault with a `vault.get` expression in the datastore config.

Stores swamp runtime data in GitLab using the Terraform state HTTP API. Provides distributed locking via GitLab's native state locking mechanism and bidirectional sync between local cache and GitLab. Emits OpenTelemetry spans for GitLab API calls, lock acquisition/release, and push/pull sync so datastore activity is visible in traces when a TracerProvider is configured. The access token is read from a swamp vault with a `vault.get` expression in the datastore config, never written literally.

Stores swamp runtime data in Azure Blob Storage using native blob-lease distributed locking (the lease ID doubles as the fencing-token nonce) and ETag-conditional writes on a shard-first path index for optimistic concurrency. Emits OpenTelemetry spans for blob operations, lock acquisition/release, and push/pull sync so datastore activity is visible in traces when a TracerProvider is configured. Supports Shared Key (account key or connection string) and Azure AD service-principal authentication. No Azure SDK dependency — talks to the Blob REST API directly via fetch. Credentials are read from a swamp vault with `vault.get` expressions in the datastore config, never written literally.

macOS Keychain vault using the security CLI. Emits OpenTelemetry spans for get, put, and list so vault reads are visible in traces, including reads during model and workflow runs where the host emits nothing. Span attributes carry the vault name, key name, and keychain service only — never secret values, argv, or error messages.

HashiCorp Vault secrets management via REST API (KV v1 and v2). Emits OpenTelemetry spans for get, put, and list, with one child span per request in the recursive list walk, so vault reads are visible in traces including reads during model and workflow runs where the host emits nothing. Span attributes carry the vault name, key name, and KV version only — never secret values, tokens, or error messages.

Stores swamp runtime data in AWS DynamoDB with conditional-write distributed locking (fencing tokens + TTL-as-defense-in-depth) and chunked blob storage for items exceeding DynamoDB's 400KB size limit. Emits OpenTelemetry spans for DynamoDB operations, lock acquisition/release, and push/pull sync so datastore activity is visible in traces when a TracerProvider is configured.
