CoreRasurae f8233000cc fix(db): add missing link_type, FK constraints, and partial index per spec DDL
Align resource_links, checkpoint_metadata, and decisions schema behavior with the spec DDL. Add SQLite runtime trigger guards for checkpoint foreign-key semantics and migration-focused Behave/Robot checks that orphan checkpoint references are rejected.

Feature: Database migration lifecycle
As a CleverAgents administrator
I want to manage database schema via Alembic migrations
So that I can safely evolve the schema with rollback capability
Background:
Given a fresh in-memory database for migration lifecycle testing
Scenario: Apply all migrations forward on a fresh database
When I run all migrations forward to head
Then the database should have all expected tables
And the current revision should be the head revision
Scenario: Spec-parity schema details are present after migration
Given all migrations have been applied
Then the "resource_links" table should include "link_type" with default "contains"
And checkpoint_metadata should enforce decision and resource foreign keys
And checkpoint_metadata foreign keys should reject orphan references
And checkpoint_metadata should reject orphan decision_id independently
And checkpoint_metadata should reject orphan resource_id independently
And checkpoint_metadata should accept valid decision and resource references
And the "decisions" table should have partial index "idx_decisions_superseded" on "superseded_by"
Scenario: Roll back all migrations to base
Given all migrations have been applied
When I downgrade all migrations to base
Then the current revision should be None
And the database should have no application tables
Scenario: Round-trip forward then rollback to initial
Given all migrations have been applied
When I downgrade to the initial migration "001_initial_schema"
Then the current revision should be "001_initial_schema"
When I upgrade back to head
Then the current revision should be the head revision
Scenario: CLI db upgrade command applies migrations
When I invoke the db upgrade CLI command
Then the CLI should report a successful upgrade
And the database should have all expected tables
Scenario: CLI db current command shows revision
Given all migrations have been applied
When I invoke the db current CLI command
Then the CLI should display the current revision
Scenario: CLI db downgrade command rolls back
Given all migrations have been applied
When I invoke the db downgrade CLI command with revision "m6_004_container_metadata_column"
Then the CLI should report a successful downgrade
Scenario: Stamp logic detects pre-Alembic database
Given a database with legacy tables but no alembic_version
When I run init_or_upgrade on the legacy database
Then the database should be stamped with alembic_version
And the database revision should be at head
Scenario: Migration orphan cleanup nullifies stale checkpoint references
Given migrations applied up to "m4_003_plan_env_columns"
And checkpoint_metadata contains orphan decision and resource references
When I upgrade to the next migration revision
Then the orphan decision_id values should be NULL
And the orphan resource_id values should be NULL
And checkpoint_metadata should enforce decision and resource foreign keys
Scenario: resource_links.link_type accepts spec-defined non-default values
Given all migrations have been applied
Then resource_links should accept link_type "references"
And resource_links should accept link_type "derived_from"
Scenario: resource_links.link_type rejects NULL values
Given all migrations have been applied
Then resource_links should reject NULL link_type
Scenario: resource_links.link_type rejects invalid values
Given all migrations have been applied
Then resource_links should reject link_type "invalid_type"
Scenario: Deleting a decision sets checkpoint decision_id to NULL
Given all migrations have been applied
And a checkpoint references a valid decision
When the referenced decision is deleted
Then the checkpoint decision_id should be NULL
Scenario: Deleting a resource sets checkpoint resource_id to NULL
Given all migrations have been applied
And a checkpoint references a valid resource
When the referenced resource is deleted
Then the checkpoint resource_id should be NULL
Scenario: Spec-parity m4_004 downgrade removes added schema objects
Given all migrations have been applied
When I downgrade to revision "m4_003_plan_env_columns"
Then the "resource_links" table should not include "link_type"
And the "decisions" table should not have index "idx_decisions_superseded"
And checkpoint_metadata should not have foreign key "fk_checkpoint_metadata_decision"
And checkpoint_metadata should not have foreign key "fk_checkpoint_metadata_resource"
And checkpoint_metadata should not have SQLite triggers for FK enforcement
Scenario: Migration idempotency: existing link_type column gains CHECK constraint
Given migrations applied up to "m4_003_plan_env_columns"
And resource_links already has a link_type column without CHECK constraint
When I upgrade to the next migration revision
Then the "resource_links" table should include "link_type" with default "contains"
And resource_links should reject link_type "invalid_type"
Scenario: Migration idempotency: existing link_type column with wrong default is corrected
Given migrations applied up to "m4_003_plan_env_columns"
And resource_links already has a link_type column with a non-contains default
When I upgrade to the next migration revision
Then the "resource_links" table should include "link_type" with default "contains"
And resource_links should reject link_type "invalid_type"
Scenario: Positive checkpoint FK test verifies persisted row
Given all migrations have been applied
And valid decision and resource rows exist
When I insert a checkpoint with valid FK references
Then the checkpoint row should be persisted in the database
Scenario: UPDATE trigger rejects orphan decision_id on checkpoint_metadata
Given all migrations have been applied
And a checkpoint exists with valid FK references
When I update the checkpoint decision_id to a non-existent value
Then the update should be rejected with an integrity error
Scenario: UPDATE trigger rejects orphan resource_id on checkpoint_metadata
Given all migrations have been applied
And a checkpoint exists with valid FK references
When I update the checkpoint resource_id to a non-existent value
Then the update should be rejected with an integrity error
Scenario: resource_links.link_type rejects empty string values
Given all migrations have been applied
Then resource_links should reject empty string link_type
Scenario: init_database creates a valid schema
When I call init_database with an in-memory URL
Then the resulting engine should have a valid schema
@issue_4180 @alembic_packaging
Scenario: MigrationRunner locates alembic.ini from packaged location
Given the MigrationRunner class is available
When I call _find_alembic_ini() to locate the configuration file
Then it should find alembic.ini at the package location
And the alembic.ini should be readable and valid
@issue_4180 @alembic_packaging
Scenario: Database initialization succeeds with packaged alembic files
Given a fresh in-memory database for migration lifecycle testing
When I run all migrations forward to head
Then the database should have all expected tables
And the database should be stamped with alembic_version
And the database revision should be at head
