Grok c055787bd4 refactor(db_migrate): extract _apply_migrations_until helper; add edge-case tests
Issue 1 (refactor): run() and migrate_to_version() duplicated the inner
loop body — every change to the migration loop had to be applied in both
places. Pull the loop into _apply_migrations_until(engine, target_version):
when target_version is None, apply all pending; otherwise stop when the
file's version exceeds target. run() and migrate_to_version() are now
thin wrappers around the helper.

Issue 2 (tests): migrate_to_version() had no direct tests for its
edge-case behavior. Add 4 tests:
- idempotent: calling migrate_to_version(engine, N) twice == once
- lower-than-current: migrate_to_version(engine, 3) after N=13 is a no-op
- zero on fresh DB: migrate_to_version(engine, 0) is a no-op
- beyond-max: migrate_to_version(engine, 999) applies every migration

Tests use a fresh sa.Engine (not db.engine()) so they exercise the
target-version behavior from a clean user_version=0 starting point —
the conftest autouse fixture has already brought the module engine to
the latest version, which would mask the no-op branches.

Tyler ced8d20aed fix(db+tests): data-preservation test for migration 0014; document before_insert events
Address the three concerns raised by the spec reviewer on commit 534130e:

1. The 0014 data-preservation test was degraded: it only verified
   post-0014 INSERTs round-trip, never proving that 0014's INSERT INTO
   claims_new SELECT * FROM claims actually carries pre-existing rows
   through the table recreation. Add migrate_to_version() helper to
   db_migrate.py and rewrite the test to seed at v=13, apply 0014, and
   assert the rows survive. Add a complementary test exercising the
   JOIN-FK tables (matches / cas_adjustments / service_line_payments /
   line_reconciliations) whose batch_id columns get populated by
   0014's JOIN against the parent tables.

2. The four SQLAlchemy ORM before_insert events on Match /
   CasAdjustment / ServiceLinePayment / LineReconciliation are
   undocumented in the codebase. Add a clear module-level docstring
   explaining what the events do, why they exist (composite-FK
   NOT NULL columns require the batch side which most call sites
   don't have readily available), when they fail (parent id not
   findable in session.new / identity_map / DB -> misleading
   'NOT NULL constraint failed' IntegrityError), and the workarounds.

3. The plan Task 1.3 Step 8 said 'do not modify production code to
   make old tests pass'. In practice production code DID need to
   change because composite-PK semantics make single-id lookups
   ambiguous. Amend the plan to acknowledge this and cite the
   s.get(Claim, X) -> s.query(Claim).filter().first() refactor as
   the example. Also document the before_insert events in Step 5.

Brings in docs/superpowers/plans/2026-06-21-cyclone-parse-decide-workflow.md
from main (this branch was created before the plan file was committed)
with Task 1.3 Step 5 and Step 8 amended per the reviewer feedback.

Tyler 534130ee2b feat(db): migration 0014 relaxes claims/remittances PK to (batch_id, id)
Migration 0014 changes the PRIMARY KEYs of claims and remittances from
single-column id to composite (batch_id, id). Enables the spec'd
cross-batch CLM01 / CLP01 collision workflow: same CLM01 in multiple
batches is now representable (resubmits), pre-flight dedup 409 path is
genuinely exercisable, force-insert can skip pre-existing duplicates.

Strategy: PRAGMA defer_foreign_keys = ON + table recreation for every
table whose FKs pointed at the old single-column PK. Tables recreated:
remittances, claims, matches, cas_adjustments, service_line_payments,
line_reconciliations. Each child table gains a batch_id (or
remittance_batch_id) column for the composite FK side; INSERT INTO new
SELECT FROM old JOINs populate it from the already-recreated parent.

Cross-table FKs (remittances.claim_id, claims.matched_remittance_id)
cannot be SQL-enforced with composite PKs (SQLite has no ALTER
CONSTRAINT). Dropped at SQL level; enforced via application-layer
invariants in store.manual_match / manual_unmatch / reconcile.run and
the dedup.preflight_* helpers.

ORM updates (db.py):
- Claim / Remittance: composite PK via explicit PrimaryKeyConstraint in
  __table_args__ (column order matches SQL: batch_id, id).
- New Claim.matched_remittance_batch_id column.
- Match / CasAdjustment / ServiceLinePayment / LineReconciliation:
  added the batch side of their composite FK to the parent table.
- SQLAlchemy before_insert events auto-populate the batch side of the
  composite FK from session.new, then identity_map, then SQL fallback.

Production code updates:
- store.manual_match / manual_unmatch: also write
  matched_remittance_batch_id on the claim (was missing).
- api.py manual-match endpoint: same fix.
- reconcile.run: same fix for auto-matched pairs.

Test updates: replaced s.get(Claim, X) with the composite key
(batch_id, id) where batch_id is known, or s.query().filter().first()
where the test only knows the id. Tests that previously inserted a Match
row pointing at a non-existent Remittance now seed the parent Remittance
so the new NOT NULL composite FK is satisfied.
