Applies fixes for every valid finding from the cubic-dev-ai code review on PR #1164. All 95 default + 4 behavior tests pass after fixes. P1 (1 fix): 1. greenfield-runnable.sql orphan refs — commented out GRANT/ALTER/ validation lines targeting objects the stripped file never creates (integration, stage, pipe, CUSTOMERS table). Marked with -- ORPHAN: prefix and header note explaining the strip scope. P2 (18 fixes): 2+21. sql-execute.test.ts rewritten as behavior tests — mocks the Dispatcher, invokes the actual tool, asserts on returned output rather than source-text regex. Catches the real regression instead of implementation markers. 3. governance POLICY_REFERENCES query — compare against fully-qualified name (db.schema.table), filter policy_kind = 'MASKING_POLICY'. 4. cost-governance retention_time column — rename from the invalid data_retention_time_in_days. 5. DV2 topology token — canonical `data-vault-2` used in both question label and branch checks so DV2-specific DDL actually emits. 6. Output format duplication — Q7 detail question now defers to Triage Q2. 7. Rollback split range — tool-safe covers steps 1–6 and 9–14 (step 7 Schemas is MANUAL, not tool-safe). 8+9. Eval test error handling — narrow catch to timeout errors only, verify file size ≥ 500 bytes, set maxBuffer to 256 MiB. 10+17. Rollback confirmation guard — repeated at top of every role block (ACCOUNTADMIN, SECURITYADMIN, SYSADMIN), plus explicit note that session-variable guards only protect whole-script execution. 11+12. topology dev-clone grants — add schema-level USAGE + CREATE TABLE + SELECT/INSERT/UPDATE/DELETE grants so the example actually works instead of granting only database-level USAGE. 13+14. Terraform variables + sensitive outputs — declare var.raw_bucket, var.aws_snowflake_role_arn, var.allowed_ip_cidrs in variables.tf bootstrap; add sensitive = true to storage_integration_aws_iam_user_arn and storage_integration_aws_external_id outputs. 15+16. PII masking gap + S3 prefix — SKILL.md now requires masking to be applied at every layer that carries the PII column forward (BRONZE + SILVER + GOLD), not just at BRONZE. Fixed S3 event notification prefix to include APP/ subfolder. 18. data-vault REVOKE UPDATE/DELETE theater removed — VAULT_LOADER_ROLE was granted INSERT-only so the REVOKE is either an error or no-op. Replaced with pattern that discovers actual grant holders via SHOW GRANTS and revokes from parent roles. 19. audit task-staleness query — joins ACCOUNT_USAGE.TASK_HISTORY to compare last successful run against 7-day window (was RESULT_SCAN only, listing every started task with a schedule). 20. audit future-grants CTE — filter granted_on = 'FUTURE_TABLE' (not 'SCHEMA') and derive database.schema from qualified `name` via SPLIT_PART. P3 (7 fixes): 22. rbac-patterns access-role list — added TRANSFORM_WRITE and ANALYTICS_WRITE definitions (were referenced but never defined). 23. TESTING.md self-contradiction — reworded Tier 3 section to reflect the manual execution done in 2026-08-25/26 and codification as remaining follow-up work. 24+25. LIVE-EVAL-RESULTS totals reconciled — greenfield 65/84 successful, 19 (0 rows); rollback 38/41 succeeded, 3 blocked by tool guard. 26. SKILL.md miscount — corrected "5 blocking" to "7 blocking"; noted Q7 dedupes against Triage Q2. 27. Eval artifacts moved to os.tmpdir() to stop dirtying the checkout. 28. Rollback confirmation comment reflects the pre-filled locator (handled as part of #10+17). 29. Audit "unexpected IPs" renamed to "distinct session IPs (manual review)" with a note about adding an allowlist filter for true outlier detection. 30. Eval test NaN guard — expect(totalCreates).toBeGreaterThan(0) before the ratio check, matching the sister rollback guard. Tests: * Contract: 91 pass (adds 4 for the newly-emitted skill rules) * SQL-execute regression: 4 pass (was 3 text-regex; now real behavior) * Model-in-the-loop eval: 13 tests, opt-in via SNOWFLAKE_SETUP_EVAL=1 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

- Around line 132-150: Update the CTEs schemas_with_table_select_grants and
schemas_with_future_table_grants to retain grantee_name and the applicable grant
scope, then compare current and future SELECT grants using schema_full,
grantee_name, and scope so coverage from a different role is not treated as
sufficient.
- Around line 141-146: Update the schemas_with_future_table_grants CTE to obtain
SELECT future-table grants from SHOW FUTURE GRANTS or another source that
exposes future grants, rather than SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_ROLES.
Normalize each returned grant scope to the same database.schema schema_full key

- Around line 133-134: Update the rollback documentation around
rollback-tool-safe.sql so it no longer presents sql_execute as a safe guarded
runner unless account validation is enforced for every statement in the runner;
otherwise remove the sql_execute execution path and direct users to the manual
runner for destructive rollback.
- Around line 133-134: Update the rollback template and emitter so the two-file
partition matches the canonical steps: schemas belong to step 7 and databases to
step 8, with all DROP SCHEMA and DROP DATABASE statements emitted only to
rollback-manual.sql. Ensure rollback-tool-safe.sql contains neither statement
type and renumber any database-drop fragment currently labeled step 5.
In @.opencode/skills/snowflake-setup/SKILL.md:
- Line 166: Update the governance policy-validation instructions around
schema_inspect to support greenfield targets: validate missing tables and
columns against the declared schema or generated DDL instead of blocking
emission, including review-only greenfield mode without a warehouse. Continue
using schema_inspect for existing targets in audit or hybrid mode, and preserve
rejection for missing columns or unexpected types when validation data is
available.
In
`@packages/opencode/test/altimate/fixtures/snowflake-setup/rollback-runnable.sql`:
- Line 45: Replace the hard-coded rollback confirmation values in each SET
rollback_confirmed_account statement with a commented placeholder or require the
caller to supply the account value, matching rollback-medallion.expected.sql.
Ensure no fixture value automatically confirms rollback for account BA06306.
In `@packages/opencode/test/altimate/snowflake-setup-eval.test.ts`:
- Line 51: Replace the module-level ARTIFACT_DIR in the Snowflake setup
evaluation tests with the per-test tmpdir fixture imported from
fixture/fixture.ts. Within each test, use await using tmp = await tmpdir() and
derive the artifact paths from that directory, preserving cleanup and isolating
concurrent runs.
In `@packages/opencode/test/altimate/tools/sql-execute.test.ts`:
- Line 33: Update the test teardown around the ALTIMATE_TELEMETRY_DISABLED
environment variable to capture its value before the test and restore that exact
value afterward, including restoring it when originally set to "true" and
deleting it only when it was initially absent. Keep the existing
dispatcher/shared-state teardown behavior intact.

Compare future grants per grantee.
Both CTEs discard grantee_name. If ROLE_A has current table SELECT and ROLE_B has the future-table SELECT, the query treats the schema as covered and misses ROLE_A’s gap. Include grantee_name and the applicable grant scope in both CTEs, then compare current and future grants by schema and grantee. (docs.snowflake.com)

<search_synthesis>
The ACCOUNT_USAGE GRANTS_TO_ROLES view does not contain records for future grants [1][2]. This view is designed to query access control privileges that have been granted on existing, individual objects to account roles, applications, application roles, database roles, instance roles, or users [1][2]. To view future grants, you should use the SQL command SHOW FUTURE GRANTS instead [3]. The following variants are available: - SHOW FUTURE GRANTS IN DATABASE <database_name> [3] - SHOW FUTURE GRANTS IN SCHEMA <schema_name> [3] - SHOW FUTURE GRANTS TO ROLE <role_name> [3] - SHOW FUTURE GRANTS TO DATABASE ROLE <database_role_name> [3] These commands list privileges granted on future objects of a specified type within the target database or schema [3]. Note that the GRANTS_TO_ROLES view has a latency of up to 120 minutes (for Account Usage) or 24 hours (for Organization Usage), whereas the SHOW commands provide real-time information [1][4]. Additionally, the GRANTS_TO_ROLES view only supports a subset of object types, which is subject to change [1][2].

Snowflake official GRANTS_TO_ROLES future grants granted_on name format
💡 Result:
<search_synthesis>
In the Snowflake GRANTS_TO_ROLES view, the NAME column contains the name of the object on which the privilege is granted [1][2]. When referring to future grants, the NAME column format typically reflects the path where those future objects will be created, often represented as the fully-qualified container (e.g., <DATABASE_NAME>.<SCHEMA_NAME>) or simply the schema/database name depending on the scope of the future grant [3][4]. Specifically, for the GRANTS_TO_ROLES view: - NAME: This column holds the name of the object on which the privilege is granted [1][5]. - GRANTED_ON: This column indicates the object kind (e.g., TABLE, DATABASE, SCHEMA) [1][6]. - Future Grants context: When you query the GRANTS_TO_ROLES view for future privileges, the NAME column will contain the name of the database or schema where the future objects will be created, as it identifies the scope of those future grants [3][4]. For further verification or to see the format in action, you can compare the results of the GRANTS_TO_ROLES view against the output of the SHOW FUTURE GRANTS command, which similarly populates a NAME column to specify the target schema or database [3][4].

Read future grants from SHOW FUTURE GRANTS. SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_ROLES does not contain future-grant records. Therefore, no row can satisfy granted_on = 'FUTURE_TABLE', and this CTE always reports no missing future grants. Use SHOW FUTURE GRANTS or another source that exposes future grants, then normalize its scope name to the same database.schema key before comparison.

Build the policy-reference key from Snowflake’s returned columns.
The query compares DB.SCHEMA.TABLE with ref_entity_name. POLICY_REFERENCES returns ref_database_name and ref_schema_name separately, while ref_entity_name contains only the object name. The NOT IN comparison therefore misses every policy association and reports every table as unmasked. Join on the three fields or construct the qualified key from the returned columns.

Do not advertise sql_execute as a guarded rollback runner.
rollback-tool-safe.sql is documented as executable through sql_execute, but the same section states that the tool creates a new session per statement. The SET does not persist, so a wrong-account rollback can continue after the guard statement. Enforce the account check in the runner for every statement, or remove this execution path for destructive rollback.

Align the rollback template with the two-file partition. The canonical dependency list assigns schemas to step 7 and databases to step 8, but the template labels database drops as step 5. The rollback fixtures also place DROP DATABASE in one rollback file. An emitter following this pattern can place tool-blocked statements in rollback-tool-safe.sql and leave the rollback incomplete. Renumber the template fragments and emit DROP SCHEMA and DROP DATABASE only in rollback-manual.sql.

Use a non-live validation path for greenfield targets.
schema_inspect resolves to the live schema.inspect handler, which calls the Snowflake connector's SHOW COLUMNS IN TABLE. It requires a configured warehouse and an existing target table. Greenfield emission can occur before those tables exist, and review-only greenfield mode may have no warehouse. The mandatory check therefore reports an error and blocks policy emission.
If the target is not yet created, validate the column against the declared schema or generated DDL. Use schema_inspect for existing targets in audit or hybrid mode. Use the declared schema or generated DDL for new hybrid targets.

Require a fresh rollback confirmation.
These hard-coded values automatically pass the guard on account BA06306. A mistaken execution against the captured eval account can therefore drop its databases, warehouses, roles, and user without an explicit confirmation. Keep the SET statement commented with a placeholder, as in rollback-medallion.expected.sql, or require the caller to supply the value.

Use a test-scoped artifact directory.
All opt-in runs use the same snowflake-setup-eval directory. Concurrent bun test processes can remove, overwrite, or validate another run's artifacts. Use await using tmp = await tmpdir() from fixture/fixture.ts and derive artifact paths inside the test.
As per coding guidelines: protect shared file-write state from async races and ensure cleanup. Based on learnings: new packages/opencode/test/altimate/ tests must use the per-test tmpdir() fixture.

Restore the original telemetry setting.
This teardown deletes ALTIMATE_TELEMETRY_DISABLED even when the caller set it before the test. If it was initially "true", later tests can unexpectedly emit telemetry. Save the original value and restore it exactly after each test.
As per coding guidelines: tests using dispatcher or similar shared state must provide teardown and isolation safe for parallel bun test execution.

P1: Do not prefill the rollback confirmation with BA06306. That value automatically authorizes destructive drops on the captured evaluation account; leave a commented placeholder and require the caller to supply the current account locator in every role block.

P2: Pause the pipe before dropping it. Emit ALTER PIPE ... SET PIPE_EXECUTION_PAUSED = TRUE immediately before this DROP PIPE, matching the safety rule already stated above.

P2: The rollback does not detach the account-level resource monitor before dropping it. Add ALTER ACCOUNT UNSET RESOURCE_MONITOR before dropping account_monitor; unsetting the warehouse monitor does not release the account attachment.

P2: When this task is emitted alongside the stage, it overrides the stage’s Parquet format with CSV_STANDARD, so Parquet files from .../accounts/ fail to load. Use the same Parquet format here, or make the stage and task format a single input-driven choice.

Adds the
snowflake-setupskill, which bootstraps or audits a Snowflake account end-to-end and emits idempotent SQL, Terraform HCL, and rollback scripts. Also fixessql_executeso real SQL failures surface as errors instead of an ambiguous(0 rows)result.New Features
snowflake-setupsupports greenfield setup, brownfield audit with remediation, and hybrid mode, and outputs DDL grouped by executing role.Bug Fixes
sql_executenow returns an explicit error result when the underlying driver reports one, so syntax and semantic failures are no longer indistinguishable from successful zero-row queries, with 4 regression tests covering the behavior.Written for commit ff58e0a. Summary will update on new commits.
