edgar-transport-contracts

Producer-owned wire contracts for the edgar_updater → ai-excel-addin boundary (design edgar-to-build-model-e2e-type-and-transport-contract-design-2026-10-22.md, ratified §4 Q1–Q8; S-XREPO-1). This package is the one owner of every closed wire vocabulary and structural invariant on that boundary: both repos pin it by version and neither re-declares a member of a contract set.

Shapes and validators only — no behaviour, no I/O, no imports from edgar_api, edgar_parser or packages/edgar_shared. Its sole dependency is pydantic>=2.10,<3.

Contents:

• enums — NonGaapOutputMetricId, NonGaapAdjustmentRole, BridgeGranularity, OmittedTableStage / OmittedTableReason (ratified 5) with LEGACY_OMITTED_TABLE_REASONS for the tolerant reader, KpiGapReason (6 + financials_unavailable), NonGaapMetricFamily, BridgeFailureReason.
• measure — MeasureUnit, Scale, ScaleProvenance, MeasureType, ScaledQuantity, EvidencedBlank.
• period — one TypedPeriod (annual|quarterly|ytd|ttm + temporal_kind) with canonical_label().
• dimensions — DimensionAxis, XbrlFactRef, and the one serialize_dimensions / parse_dimensions (|-joined, escaped) form.
• kpi — KpiDriverRowsV2, TypedKpiObservation, OmittedTable, KpiLaneGap, ReaderRecord.
• tables — FilingTableEnvelope and TableBinding / ColumnBinding / RowBinding / CellRef, published as extra="forbid" models.
• non_gaap_bridge — IssuerNonGaapBridgeV3 (canonical_output_metric + output_metric_slug, effective_metric_key, producer-minted bridge_id, granularity, typed closure: BridgeClosureState, flattened subtotals — no chained_from) and IssuerNonGaapBridgeResponseV3. Its rounding_consistent diagnostic preserves the printed-equation residual within the half-ulp budget; like other ordinary diagnostics, it does not carry metric-context fields (effective_metric_key, period, or label).
• canonicalize — OUTPUT_METRIC_SURFACE_FORMS and classify_adjustment_role, beside the enums they feed.
• version — CONTRACT_VERSIONS and version_refusal(received, expected).
• golden — the 13-issuer golden pack skeleton and its golden.load(issuer, kind) loader (contents land in S-XREPO-5).

Install for development from the producer repo root: pip install -e packages/edgar_transport_contracts. Run its tests with .venv/bin/python -m pytest packages/edgar_transport_contracts/tests -q.
