# `mix threadline.verify_coverage`
[🔗](https://github.com/szTheory/threadline/blob/v0.5.0/lib/mix/tasks/threadline.verify_coverage.ex#L1)

Verifies that tables listed in application config have Threadline audit
triggers installed, using the same catalog queries as `Threadline.Health.trigger_coverage/1`.

## Configuration

Hosts must set a non-empty list of public table names (strings only):

    config :threadline, :verify_coverage,
      expected_tables: ["users", "posts"]

## Usage

    mix threadline.verify_coverage
    mix threadline.verify_coverage --schema=NAME

Prints a `TABLE` / `STATUS` report to stdout, then a line containing `summary:`
with counts. Exits with status **1** if any expected table is missing or
uncovered; exits **0** when all expected tables are covered.

Table names in output are public-schema metadata only (same scope as `Health`).

## Schema scope (Phase 66)

By default, this task verifies the `"public"` schema. Pass `--schema=NAME`
to verify a non-`public` schema (e.g. `mix threadline.verify_coverage --schema=tenant_42`).
NAME is validated at the edge (regex + `pg_namespace` lookup); invalid input
exits 1 via `Mix.raise/1`.
