Outcome

Cornerstone staff can create a verified migration-test client from a locked historical payroll import, practice with the copied employee/payroll setup, and keep the clean migration client untouched.

What changed

  • Adds a first-class migration rehearsal company environment linked to one live source client and one exact locked import batch.
  • Copies company setup, employee setup and encrypted fields, staff access, the immutable historical archive, YTD bridge data, and retained source files.
  • Re-verifies file hashes, record counts, and payroll totals before the rehearsal becomes ready.
  • Forces all rehearsal pay periods into parallel mode and blocks commit, checks, payments, official filing actions, and invoice side effects at the API layer.
  • Adds preview, acknowledgement, asynchronous preparation, failure/retry, ready-to-test status, direct open action, company-switcher labeling, and a persistent warning banner.
  • Keeps draft setup work available; historical YTD continuity is still required before practice calculations.
  • Excludes client portal content, messages, documents, native paid payroll, filings, time-tracking connections, payroll-intake connections, reminders, and audit history.

Verification

  • API: 2,356 examples, 0 failures
  • Web: 58 tests passed
  • ESLint: passed
  • TypeScript/Vite production build: passed
  • Zeitwerk eager-load check: passed
  • Brakeman: 0 security warnings
  • RuboCop: all 21 changed app/spec/migration Ruby files passed; the repository-wide run still reports pre-existing style debt outside this change
  • Browser: created the rehearsal from Client Management, observed Preparing to Ready, switched directly into it, verified the copied employee and locked imported period, confirmed exact synthetic gross/net totals, created a parallel-only draft, and confirmed commit returns 403
  • Migration rollback/reapply verified on a disposable database

Operational notes

The copy runs in a background job and uses private object storage. No production data was used during local verification. The disposable database, copied fixture files, servers, and browser tab were removed after testing.

  • Adds migration rehearsal clients linked to one live source company and one locked historical payroll batch.
  • Copies payroll setup, employees, staff access, encrypted fields, immutable archive data, YTD bridges, adjustments, and retained source files. It verifies hashes, record counts, and payroll totals before marking the rehearsal ready.
  • Adds preview, acknowledgement, asynchronous creation, retry, polling, direct opening, status fields, company-switcher labels, and a persistent warning banner.
  • Forces rehearsal pay periods into parallel mode. Blocks commit, payments, checks, filing-ready actions, and related API side effects.
  • Adds MigrationRehearsal::Preview, Create, Dispatch, Retry, Cloner, and CloneJob services, plus safety policy enforcement across admin and official-action controllers.
  • Adds company environment and rehearsal tracking fields, foreign keys, check constraints, scoped live-company EIN uniqueness, and live-only organization seat counts.
  • Excludes portal content, messages, documents, native paid payroll, filings, integrations, reminders, and audit-history cloning.
  • Material risks are controlled by source-batch locking, same-organization validation, transactional setup, cleanup on failure, hash and financial-total verification, and explicit retry handling.
  • Validation covered API, web tests, linting, build, eager loading, security scanning, browser testing, and migration rollback/reapplication.
  • Breaking changes: None reported.
  • Follow-up: Operators must use a locked historical import with verified YTD bridge data before running payroll calculations in a rehearsal.

Inline comments:
In `@api/app/controllers/api/v1/admin/companies_controller.rb`:
- Line 19: Restrict the enforce_migration_rehearsal_safety! skip in the
companies controller to only the three migration rehearsal actions, leaving
update and all other actions subject to the readiness check. Use the
controller’s existing rehearsal action names when scoping the skip.
- Line 199: Update both company index query scopes to preload the
migration_source_company association with includes(:migration_source_company)
before mapping companies to migration_source_company&.name, preserving the
existing filtering and response behavior.

In `@api/app/policies/migration_rehearsal_safety_policy.rb`:
- Around line 4-25: Make MigrationRehearsalSafetyPolicy fail closed by allowing
only explicitly classified rehearsal-safe actions, rather than returning false
for unlisted actions through blocked?. Update
migration_rehearsal_safety_policy.rb lines 4-25 and adjust
migration_rehearsal_safety_policy_spec.rb lines 7-11 to assert that an unlisted
mutating action is blocked.

In `@api/app/services/migration_rehearsal/cloner.rb`:
- Line 196: Update the source_file_map construction in the migration cloner to
key entries by each source file’s ID, matching the integer key used by
report.historical_import_source_file_id in source_file_map.fetch. Add a cloner
spec covering a HistoricalTaxWageReport to verify this path completes without
KeyError and performs copy verification.
- Around line 77-111: Merge the configuration review `update_columns` operations
into the employee child-copy loop so employees are traversed only once after
creation and predecessor linking. Before that loop, preload all six child
associations used by `copy_collection` and the `employee_deductions`
association; process deductions in deterministic ID order, preserving existing
copy arguments and review-column ordering.
- Around line 24-25: Refactor the workflow around copy_source_files! into a
short reservation transaction that locks the company and reserves the rehearsal,
perform downloads, upload, and verification outside any
ApplicationRecord.transaction, then use a separate short transaction for
persistence. Preserve duplicate-job protection by retaining
company/source-batch-based storage_prefix handling and ensuring
cleanup_existing_uploads! runs while holding the reservation lock before
transfers begin.
- Line 246: Update the adjustment lookups in the migration rehearsal cloner to
use subqueries instead of materializing IDs with paycheck_map.keys or
adjustment_map.keys. Reuse the existing source_adjustments relation for the
event lookup, preserving the source-batch relationship and avoiding large Ruby
allocations and SQL bind lists.

In `@api/app/services/migration_rehearsal/create.rb`:
- Line 12: Reorder the keyword parameters in initialize so the required
acknowledgement keyword appears before the optional name keyword, while
preserving the existing parameter names and behavior.
- Around line 42-64: Update Create#call so the transaction that persists the new
company also records durable dispatch state (such as an outbox entry) for the
clone operation, then arrange for that state to enqueue CloneJob through an
after-commit recovery path. Ensure process termination between commit and
dispatch leaves recoverable work, while preserving the existing Dispatch.call
behavior and enqueue-exception handling.

In `@api/app/services/migration_rehearsal/dispatch.rb`:
- Around line 9-28: Update the failure path in Dispatch.call to return the
persisted failed company after recording the failure instead of raising
ArgumentError. Preserve the status, error, audit log, and existing successful
dispatch behavior so Create#call and Retry#call can return the failed company to
the controller.

In `@api/app/services/migration_rehearsal/retry.rb`:
- Around line 37-38: Update Retry#call to persist a durable outbox/dispatch
record with pending status in the same transaction that commits the company
state, before invoking Dispatch.call. Add recovery handling so a redispatch
worker processes pending records and recreates the missing CloneJob after
process termination, while preserving the existing dispatch behavior for
successfully completed records.

In `@api/spec/models/company_migration_rehearsal_spec.rb`:
- Around line 49-56: Add regression coverage around the company setup in the
migration rehearsal spec to verify that creating a second active rehearsal for
the same migration source is rejected, while a rehearsal for a different source
remains valid. Exercise the existing MigrationRehearsal::Create behavior and
assert the one-active-rehearsal-per-source constraint without changing runtime
code.

In `@api/spec/requests/api/v1/admin/migration_rehearsal_safety_spec.rb`:
- Around line 40-53: Extend the migration rehearsal safety request examples to
cover check printing and invoice creation: post to the endpoints handled by
CheckPrintRunsController#create and InvoicesController#create, assert forbidden
responses, and verify no CheckPrintRun or Invoice record is created. Do not add
coverage for payroll-liability payments, since that controller only exposes
reconciliation through index.

In `@api/spec/services/migration_rehearsal/cloner_spec.rb`:
- Around line 119-122: Update the cleanup in the migration rehearsal specs to
track each created rehearsal company ID, such as through a shared
`@rehearsal_company_ids` collection, and have the after hook list and delete
objects using each company’s specific batch prefix. Preserve deletion of
source_key and ensure all examples creating rehearsal companies record their
target.id.
- Around line 242-258: The MigrationRehearsal retry failure path must reload the
company before evaluating the rescue status guard, ensuring the guard uses the
rolled-back database state and records migration_rehearsal_error. Update
MigrationRehearsal::Retry accordingly and add a regression spec covering a copy
failure after the status is set to ready.

In `@web/src/pages/Clients.tsx`:
- Line 321: Update the new rehearsal card spacing utilities to use the nearest
8px-grid Tailwind values: replace p-5, mt-5, and pl-5 in the card markup with
the appropriate even-numbered utilities while preserving the existing layout.
- Around line 143-147: Update the polling effect around load so pending
rehearsal refreshes use a quiet fetch path that does not call setLoading(true)
or replace the existing client list with the loading state. Preserve the current
loading behavior for initial or user-triggered loads, and continue polling only
while a company has migration_rehearsal_status equal to pending.
- Around line 369-370: Associate the rehearsal name label and Input in Clients
by following the existing useId pattern from SettingToggle: create a stable id
near Clients’ other hooks, assign it to the Input, and set the label’s htmlFor
to the same id.
- Around line 620-632: Update the Badge variant selection in the client status
rendering to use the informational variant when migration_rehearsal_status is
pending, before the failed branch, while preserving the existing active/inactive
behavior for other statuses.

Final review disposition for current head c9392a74:

  • Fixed the source-file key mismatch, rollback/failure-state bug, duplicate-job cleanup race, company safety-hook scope, source-company preload, adjustment query allocations, quiet polling, pending-state badge, field labeling/spacing, staff-only rehearsal access, and the remaining stateful check-signoff export guard.
  • Kept rehearsal action safety targeted instead of converting it to a blanket allowlist: the product intentionally permits staff to edit copied setup, calculate parallel practice payroll, and inspect comparison reports. Pay periods have a model-level non-committable invariant, while check/payment/official-filing actions are explicitly blocked.
  • Kept the clone as one background repeatable-read copy transaction so employee setup, archive records, YTD bridges, and verification represent one exact source snapshot. Splitting persistence around object-storage transfers would require a new reservation/outbox state machine and carries more consistency risk than this one-time background workflow warrants here.
  • Did not add a new generic outbox subsystem or duplicate lower-value coverage after the corrected implementation received CodeRabbit's explicit clean correctness/security/data-integrity review at 0c84266d. Enqueue exceptions are persisted as failed and retryable; the later commits are bounded safety/UX fixes.

Verification: 2,361 API examples passed locally, focused request/service/model specs passed after the final safety-hook correction, 58 web tests passed, ESLint passed, production build passed, and browser testing covered clone creation, ready-state switching, exact imported totals, copied employee setup, parallel-run enforcement, and the blocked commit response. Current CI is running on this exact head.
