From 6bdf670ffc4bb500754ad310bd1a0030d463e83e Mon Sep 17 00:00:00 2001 From: infinityplusone Date: Mon, 11 May 2026 20:00:49 -0400 Subject: [PATCH 01/28] feat(node): expand webhook subscription + endpoint write methods Bring `createWebhookSubscription` / `updateWebhookSubscription` and `createWebhookEndpoint` / `updateWebhookEndpoint` up to API parity: - Subscriptions now accept the canonical request shape directly (`subscription_name`, `endpoint`, `subscription_type`, `event_type`, `subject_type`, `subject_ids`, `query_type`, `filter_definition`, `frequency`, `cron_expression`, ...). Legacy `{ subscriptionName, payload }` still works. - Endpoints now accept `name` (required by the API), in addition to `callback_url` and `is_active`. Legacy `{ callbackUrl, isActive }` still works; missing `name` defaults to the URL host so old call sites don't need updating immediately. - Add a dedicated `testWebhookEndpoint(endpointId)` method that mirrors the API's `endpoint_id` request key. The pre-existing `testWebhookDelivery({ endpointId? })` is kept as a legacy alias. New types in `models/Webhooks.ts`: `WebhookSubscriptionCreateInput`, `WebhookSubscriptionUpdateInput`, `WebhookEndpointCreateInput`, `WebhookEndpointUpdateInput`.

charset=UTF-8 Content-Transfer-Encoding: 8bit The audit caught the README claiming `timeout` and `retries` constructor options that didn't exist. Make the docs correct in both directions: - `timeoutMs` (canonical, already supported) keeps working. - `timeout` is now accepted as a shorthand alias — both are in milliseconds. If both are supplied, `timeoutMs` wins. - `retries` and `retryBackoffMs` are accepted on `TangoClient` and forwarded to `HttpClient`. Defaults: 3 retries, 250ms initial backoff (doubles per attempt, capped at 10s).

Adds: Lookups: listNaics/getNaics, listPsc/getPsc, listMasSins/getMasSin, listAssistanceListings/getAssistanceListing, listOrganizations/getOrganization, listOffices/getOffice, listDepartments (marked @deprecated — use listOrganizations({ level: 1 }) instead). Awards completeness: listOtas/getOta, listOtidvs/getOtidv, listOtidvAwards, listSubawards, listGsaElibraryContracts, listLcats (accepts { uei } or { idvKey }). Other: listProtests/getProtest, listItDashboard/getItDashboard, listMetrics (parameterized by ownerType: naics | psc | entity), plus resolve() and validate() POST endpoints. All option interfaces re-exported from src/index.ts for downstream typing. No model classes added — returns Record / PaginatedResponse>, matching the loose shape contract already in place for vehicles/idvs. Webhook write methods and constructor/retry surface untouched — owned by feat/api-parity-writes.

Mirrors the Python algorithm byte-for-byte (lowercase hex HMAC-SHA256, `sha256=` header format) and accepts the same legacy bare-hex input. `parseSignatureHeader` returns `{ algorithm, signature }` (instead of the Python helper's bare string) so callers can introspect the algorithm — the Node API gets a tiny ergonomic upgrade since we're defining the shape fresh. `verifySignature` uses Node's `timingSafeEqual` for constant-time comparison and never throws on mismatch; returns false for missing, empty, malformed, wrong-algorithm, or wrong-length headers.

README.md: - Fixed broken link `SHAPED.md` -> `SHAPES.md` in the project structure tree. - Repaired garbled Dynamic Models link ("ynamic shaping system** works."). - Replaced 10-method stub API list with a comprehensive breakdown of all ~84 public methods. docs/API_REFERENCE.md: - Added sections for previously undocumented method groups: Organizations/Offices/Departments, OTAs, OTIDVs, Subawards, GSA eLibrary, Protests, IT Dashboard, LCATs, Metrics, Reference Lookups (NAICS/PSC/MAS/CFDA), Resolve/Validate, Entity Sub-resources, Agency Sub-resources, Opportunity Attachments, Async Iteration helpers, Utility, Webhook Alerts. - Removed a duplicated `listBusinessTypes` section. - Added `@deprecated` notice to `listDepartments` (source marks it deprecated in favor of `listOrganizations({ level: 1 })`). - Fixed `searchOpportunityAttachments` example — `limit` doesn't exist on that method; actual interface is `{ q, topK?, includeExtractedText? }`. - `testWebhookDelivery` is the legacy alias; `testWebhookEndpoint(endpointId)` is the preferred form. - Expanded `createWebhookSubscription` section to document both canonical and legacy payload shapes. docs/SHAPES.md: - Fixed "Flat Responses" section — was self-referential and didn't explain that `flat: true` causes the API to return dotted keys. Added before/after example. - Added `ShapeConfig Presets` section listing the 12 available presets.

Pre-fix the TS shape generator hardcoded allowlists that didn't include the canonical `naics`/`psc` expand form — running through TypeGenerator + SchemaRegistry would have rejected canonical inputs once #2259 deployed. Verified the shape system is NOT pure validation — it drives type coercion in ModelFactory via TypeGenerator → SchemaRegistry. So Option 1 (drop) would have lost real behavior. Picked Option 2 (mirror alias map): - Added `EXPAND_ALIASES` + `normalizeExpandAlias` in `src/shapes/generator.ts`. Rewrites `naics_code(...)` → `naics(...)` and `psc_code(...)` → `psc(...)` only when nested fields are present. Bare scalar `naics_code` / `psc_code` are left alone, matching server semantics. - Added canonical `naics`/`psc` (nested CodeDescription) entries to CONTRACT/OPPORTUNITY/NOTICE/FORECAST/VEHICLE schemas in `src/shapes/explicitSchemas.ts`. Tests: 9 new cases in `tests/unit/shapes.generator.test.ts`. 60/60 tests pass, typecheck/build/prettier clean, zero new lint errors.

All addressed in this drop. Conformance gate now green (0 errors, 0 warnings). Test suite: 220 passing, up from 146. Highlights: - **Typed Options interfaces** for every list method matching Python kwargs. Forecasts, Opportunities, Notices, Grants had no typed filters at all; now ship full interfaces. Contracts/Entities/Vehicles/IDVs/OTAs/OTIDVs expanded to mirror Python's complete signature. `[key: string]: unknown` index sigs retained for forward-compat. - **9 missing ShapeConfig presets** added (PROTESTS_MINIMAL, OTAS_MINIMAL, OTIDVS_MINIMAL, SUBAWARDS_MINIMAL, GSA_ELIBRARY_CONTRACTS_MINIMAL, ORGANIZATIONS_MINIMAL, VEHICLE_ORDERS_MINIMAL, ITDASHBOARD_INVESTMENTS_MINIMAL/_COMPREHENSIVE) + drift fixes to ENTITIES_COMPREHENSIVE, VEHICLES_MINIMAL, VEHICLES_COMPREHENSIVE. - **11 missing explicit schemas** added (ORGANIZATION, OTA, OTIDV, SUBAWARD, PROTEST, PROTEST_DOCKET, GSA_ELIBRARY_CONTRACT/IDV_REF, ITDASHBOARD_INVESTMENT, VEHICLE_METRICS, ORGANIZATION_OFFICE). VEHICLE_SCHEMA extended with the fields the updated VEHICLES_* presets reference. - **Typed return models** for `resolve` (ResolveResult), `validate` (ValidateResult), `getAgency` (AgencyRecord), `getProtest` (ProtestRecord). Replaces `AnyRecord` returns. - **`rateLimitInfo` + `lastResponseHeaders`** instance properties on TangoClient, populated by HttpClient after every successful response. - **`listContracts` cursor pagination** added (non-breaking) — `cursor` alongside `page` in ListContractsOptions; PaginatedResponse gains a `cursor` field auto-extracted from `next`. - **WebhookReceiver framework** (src/webhooks/receiver.ts): dataclass-style with `start/stop/url/deliveries/onDelivery/forwardTo`, both `await using` + `withRunning` patterns. Pure `node:http` + native `fetch`. - **Webhook simulator** (src/webhooks/simulate.ts): `sign()` + `deliver()` with stable-stringify helper matching Python's `sort_keys=True` byte-for-byte. - **`tango-node` CLI** (src/bin/tango-node.ts + src/webhooks/cli.ts): commander-based, mirrors Python `tango webhooks` subcommands (listen/simulate/trigger/fetch-sample/list-event-types/endpoints{...}). New dep: commander@^12.1.0. - **Conformance script** (scripts/check-filter-shape-conformance.ts): walks src/client.ts with the TypeScript Compiler API, validates against the canonical filter/shape manifest. `npm run check-conformance` → `{errors: [], warnings: []}` (parity with Python conformance gate). - **Generator fix**: `field(*)` wildcard on dict-typed fields now works without requiring a nested model (Python parity). Was throwing ShapeValidationError on `federal_obligations(*)` etc. New devDep: tsx (for running the conformance script).

Includes a `stableStringify` helper that matches Python's `json.dumps(sort_keys=True, separators=(",", ":"))` byte-for-byte so signatures are reproducible across languages. + +#### Webhook CLI — `tango-node webhooks` + +New `bin/tango-node` (entry in `src/bin/tango-node.ts`) backed by `commander`. Subcommands: `listen`, `simulate`, `trigger`, `fetch-sample`, `list-event-types`, `endpoints {list, get, create, delete}` — mirroring the Python `tango webhooks` CLI. New runtime dep: `commander@^12.1.0`. + +#### Conformance gate + +New `scripts/check-filter-shape-conformance.ts` + `npm run check-conformance` script. Walks `src/client.ts` with the TypeScript compiler AST, extracts each `list*` method's `Options` interface, and validates against the canonical manifest at `tango/contracts/filter_shape_contract.json`. JSON output + exit codes match the Python conformance script. Current state: **0 errors, 0 warnings** — parity verified. + +#### Test coverage + +Net **+74 tests** across the new work (220 total now passing, up from 146 pre-audit): + +- ShapeConfig preset parity (`config.shapes.parity`) +- Explicit schema parity (`shapes.schema.parity`, 12 tests) +- WebhookReceiver lifecycle, signature paths, forwarding, history cap, `withRunning` + `Symbol.asyncDispose` (`webhooks/receiver`, 21 tests) +- Webhook simulator stable-stringify, sign-verify round-trip, deliver against a real `http.createServer`, timeout (`webhooks/simulate`, 17 tests) +- CLI subcommand wiring (`webhooks/cli`, 7 tests) +- Conformance script (`scripts/conformance`, 5 tests) +- Observability + cursor pagination + typed return models (`client.observability`, 11 tests) + +### Internal + +- `tsx` added as a devDependency to run the new conformance script. +- `HttpClient` constructor body unchanged;
