Description
Activity
AUTHOR claim
Role: AUTHOR
Scope: Implement REQ-MARKET-004 — transaction schemas for local market settlement and tax integration
Branch: claude/issue-255-market-transaction-schemas
Status: status:in-progressNo known blockers at claim time. REQ-MARKET-003 is IMPLEMENTED; REQ-CORE-006 is partially implemented but the current issue is labeled status:ready, so proceeding with implementation.
AUTHOR handoff: REQ-MARKET-004 implementation complete
Branch: claude/issue-255-market-transaction-schemas
Tested revision: 05a5dc8 (REQ-MARKET-004 ledger row: Correct PR number to #298)
PR: #298Implementation Complete
Implemented transaction schemas for local market settlement and tax integration per section 12 of MARKETS_TRADE_FX_CONTRACTS.md:
Core Work:
- Added TransactionId, TransactionBundleId, FxSettlementId types (domain/id.ts)
- Extended EconomicTransaction with transactionId, bundleId, originatingTransactionId, fxSettlementId
- Created src/simulation/transactionSchemas.ts with factory functions:
- createMarketSaleTransaction(): MARKET_SALE with correct seller-net value
- createConsumptionTaxTransaction(): CONSUMPTION_TAX with collectionEfficiency handling
- Implemented validation functions for both transaction types
Test Coverage (36+ tests):
- MARKET_SALE creation with quantity/price calculations
- CONSUMPTION_TAX creation with proper STATE destination
- Tax calculation with collectionEfficiency (0.5, 0.75, 1.0)
- Edge cases: null destinationStateId, zero tax amounts
- Bundled transaction semantics (shared bundleId, originating linkage)
- Validation of required fields and proper formatting
Acceptance Criteria Status
✓ MARKET_SALE transaction schema defined with all required fields
✓ CONSUMPTION_TAX transaction schema defined with all required fields
✓ EconomicTransaction extended with transactionId, bundleId, originatingTransactionId, fxSettlementId
✓ Tax calculation correctly applies collectionEfficiency (only collected tax transacted)
✓ Bundled paired transactions have identical bundleId
✓ Comprehensive test coverage proving transaction construction and bundling
✓ TypeScript: npm ci, npm run typecheck, npm test (456 tests), npm run build all pass
✓ C#/.NET: dotnet restore/build/test all pass (45/45 tests, REQ-MIGRATION-003 maintained)Verification Results
Canonical TypeScript:
- ✓ npm ci (success)
- ✓ npm run typecheck (0 errors)
- ✓ npm test (456 tests passed, +36 new)
- ✓ npm run build (0.15 kB gzipped)
Legacy C#/.NET:
- ✓ dotnet restore (success)
- ✓ dotnet build --configuration Release (0 warnings, 0 errors)
- ✓ dotnet test --configuration Release (45/45 tests passed)

Highest-Risk Area for Review
Tax-related transaction linkage: ensure that assessed-but-uncollected tax calculations are correct and stay outside the transaction record (telemetry only). The collectionEfficiency handling must be validated against HANDOFF-REPAIR-006 requirements.

Tested revision: 123a855 (REQ-MARKET-004: Fix transaction schema completeness and add ledger row)
PR: #298
Issue: #255
Status: All acceptance criteria met. Schema and validation complete. Ready for ACCEPTOR review.
What was fixed
-
Schema completeness (SLOPSTER QA finding Make the economy actually run: close the loop, fix pricing and trade #1): Added missing fields to MARKET_SALE:
quantity(required, validated > 0)sourceRegionId(required, validated non-empty)destinationRegionId(required, validated non-empty)
-
Required transactionId (SLOPSTER QA finding Make the economy actually run: close the loop, fix pricing and trade #2): Made
transactionIdrequired (not optional) onEconomicTransaction- Type-level enforcement prevents transactions without identity
- Runtime validator enforces presence
- Enables deterministic reconciliation and tax linkage per spec
-
Enhanced validation:
- Added negative-control test proving schema rejects missing quantity and region fields
- Validator checks quantity is finite and > 0
- Validator checks region IDs are present
-
Ledger administration: Added REQ-MARKET-004 row to implementation_status.csv per AGENTS.md policy (PR REQ-MARKET-004: Transaction schemas for local market settlement #298, merge commit to be backfilled by script)
Verification
TypeScript (Canonical)
- ✓ npm ci
- ✓ npm run typecheck (0 errors)
- ✓ npm test (457 tests: 456 baseline + 1 new schema enforcement test)
- ✓ npm run build (0.15 kB gzipped)
C#/.NET (Legacy)
- ✓ dotnet restore
- ✓ dotnet build --configuration Release --no-restore (0 warnings)
- ✓ dotnet test --configuration Release --no-build (45/45 tests, REQ-MIGRATION-003 maintained)
Decision: Type-level schema enforcement
Made
transactionIdrequired onEconomicTransactioninterface (not optional). This is a breaking change to the interface, but:- Required by spec for reconciliation/tax linkage (section 12, Scope, and Issue acceptance criterion)
- All existing code in canonical tree passes with this change
- Factory functions always populate it
- Tests prove schema enforcement
- Legacy code unaffected
Remaining work
No remaining work. All acceptance criteria #1-8 satisfied:
- ✓ MARKET_SALE schema defined with all required fields
- ✓ CONSUMPTION_TAX schema defined with all required fields
- ✓ EconomicTransaction extended with transactionId (required), bundleId, originatingTransactionId, fxSettlementId
- ✓ Tax calculation correctly applies collectionEfficiency
- ✓ Bundled paired transactions have identical bundleId
- ✓ Comprehensive test coverage (457 tests, including negative controls)
- ✓ TypeScript: all checks pass
- ✓ C#/.NET: all checks pass (REQ-MIGRATION-003 maintained)
Ready for ACCEPTOR review and merge gate decision.

AUTHOR Blocker Report
Gate:
policy-guardcheck fails due to conflicting requirementsFailure:
test_no_row_that_names_a_merged_pull_request_lacks_its_commitrejects ledger row for REQ-MARKET-004Root Cause:
- AUTHOR_RUNBOOK section 7 requires: Add ledger row inside the PR, naming this PR's number, with MERGE_COMMIT empty
test_backfill_merge_commits.pyline 114 requires: All rows naming a PR must have a non-empty MERGE_COMMIT- These requirements conflict and cannot both be satisfied during the PR's open state
Evidence:
- PR REQ-MARKET-004: Transaction schemas for local market trade #301 adds ledger row: REQ-MARKET-004,IMPLEMENTED,255,301,,
- CI run fails with: AssertionError: Lists differ: ['REQ-MARKET-004'] != []
- This same issue is tracked as Issue PR #295 closed #292 while the pre-merge provenance guard remains unfixed #297 (SLOPSTER QA finding): "PR REQ-MARKET-003 ledger provenance: repair missing row from merged PR #293 #295 closed Ledger provenance self-test rejects the required pre-merge row shape #292 while the pre-merge provenance guard remains unfixed"
What Would Unblock:
- Fix the test in a separate policy PR to skip merge-commit validation on non-master branches
- Or clarify the AUTHOR_RUNBOOK regarding when ledger rows should be added
Status: Blocking REQ-MARKET-004 implementation pending resolution of Issue #297.

Addressed ACCEPTOR policy feedback and SLOPSTER QA finding from PR #301:
-
Tax identity check (MTFX-I2): Fixed
preflightMarketSettlement()to enforce exact equality (with epsilon tolerance 1e-8) rather than just a minimum threshold. Now correctly rejects both insufficient AND excessive buyer debit. -
Test fixtures: Corrected multiple test allocations that violated the tax identity constraint:
- MTFX-T4 test:
buyerGrossUnitPrice112 → 100.8 (now matches identity exactly) - Rejection test: Updated error message expectation to "must equal"
- Tax=0 tests: Added explicit
buyerGrossUnitPrice=10to match identity
- MTFX-T4 test:

Goal
Implement transaction schemas for local market settlement and tax integration, establishing the definitive record of buyer/seller obligations and tax collections for deterministic reconciliation.
Evidence
Specification: docs/spec/mirror/06 - Handoff/04 — MARKETS_TRADE_FX_CONTRACTS.md, section 12
Scope
Implement two transaction types:
MARKET_SALE transaction
CONSUMPTION_TAX transaction
Extend EconomicTransaction with required fields:

Notes
This requirement depends on:
Current blocking status: REQ-MARKET-003 (#251) and REQ-CORE-006 (#226) are in-progress. This issue will be ready for claiming once both dependencies are merged and the M2 gate closes.
The tax-policy read boundary (getConsumptionTaxRate, getCollectionEfficiency) is injected by M3 tests; M6 later replaces it with effective FiscalPolicyState.
