# LSSM OS GCP queue transports

This package hardens GCP Pub/Sub and Cloud Tasks as optional wake-up transports
over the SQL-authoritative LSSM OS durable queue. Messages contain only immutable
envelope/outbox identifiers and digests. SQL owns admission, claims, fences,
acknowledgements, reconciliation, and effect authority. Pub/Sub acknowledgement
or Cloud Tasks callback completion happens only after durable SQL completion.


## Declared capabilities

### GCP queue wake-up transports

Capability ID: `lssm-os.queue.gcp`

Use GCP Pub/Sub or Cloud Tasks as optional wake-up transports while SQL retains durable LSSM OS queue and effect authority.

Use cases:

- Wake SQL-authoritative workers from GCP Pub/Sub messages
- Complete Cloud Tasks callbacks only after durable SQL acknowledgement

Constraints:

```json
{
  "platforms": [
    "server"
  ],
  "runtimes": [
    "bun",
    "node"
  ],
  "avoidWhen": [
    "Pub/Sub or Cloud Tasks must own admission, claims, fences, reconciliation, or effect authority.",
    "Messages must carry payloads, secrets, claims, or provider results instead of immutable references and digests."
  ],
  "requires": [
    "GCP transport driver",
    "SQL-authoritative durable queue"
  ]
}
```

Other capability declarations:

```json
{
  "status": "active",
  "aliases": [
    "GCP Pub/Sub",
    "Cloud Tasks",
    "queue wake-up"
  ],
  "pythonEquivalents": [
    "google-cloud-pubsub",
    "google-cloud-tasks"
  ],
  "alternatives": [],
  "relationships": [],
  "resolutionPriority": 65
}
```

Capability imports:

```json
[
  {
    "from": "@lssm-tech/integration.lssm-os-queue-gcp",
    "symbols": []
  }
]
```

## Catalogue metadata

```json
{
  "family": "integrations",
  "kind": "integration",
  "status": "active",
  "adoptionMode": "adoptable",
  "stability": "experimental",
  "platforms": [
    "server"
  ],
  "runtimes": [
    "bun",
    "node"
  ],
  "entrypoints": [
    "."
  ],
  "examples": [],
  "replacements": []
}
```

## Canonical imports

Import paths and symbols below are catalogue declarations. An empty symbols list means symbols were not enumerated; it does not mean the entry point has no exports. These declarations are not an exhaustive TypeScript symbol reference.

```json
[
  {
    "capabilityId": "lssm-os.queue.gcp",
    "from": "@lssm-tech/integration.lssm-os-queue-gcp",
    "symbols": []
  }
]
```

## Declared export entry points

Scope: manifest-declared export entrypoints and catalog-declared imports.

Named symbol coverage: catalog declarations only; exhaustive TypeScript symbols not extracted.
