Summary

Syncs the Python SDK to Tango API v4.6.9. The v1.0.0 parity sweep closed most of the historical gap; this closes the rest of the agreed-on surface and fixes three real bugs. Version bump 1.0.0 → 1.1.0.

Paired with makegov/tango-node — both PRs keep the cross-SDK parity tests green.

Phase 1 — Bug fixes

  • Contract model: dropped dead fields (id, award_id, recipient_name, award_amount, awarding_agency, funding_agency) that the API has never returned; added the real ContractListSerializer field set (key, piid, obligated, total_contract_value, awarding_office, funding_office, naics_code, psc_code, set_aside, legislative_mandates, subawards_summary, place_of_performance, …). Old fields retained as Optional/None with a deprecation note → removed in 2.0.0. (This dataclass is documentation-only — not instantiated or exported — so no runtime breakage.)
  • list_contracts: stopped sending page=1 to /api/contracts/, which is cursor-only (KeysetPagination) and ignores page.
  • list_otidv_awards added (parity with Node's listOtidvAwards).

Phase 2 — Additive surfaces

  • Budget accounts (the headline new surface): list_budget_accounts, get_budget_account, get_budget_account_quarters, get_budget_account_recipients + BudgetAccount model + shape schema.
  • Singleton detail GETs: get_contract, get_contract_subawards, get_contract_transactions, get_forecast, get_grant, get_notice, get_opportunity, get_subaward.
  • get_entity_budget_flows(uei).
  • grant_id filter on list_grants.

Phase 3 — CI

  • Re-enabled lint.yml as a PR gate (ruff format/check + mypy); conformance split into a separate non-blocking job.

Deferred (by decision)

accounts/usage (internal), G2X events/news/company-rag, canonical webhook-subscriptions CRUD, PUT/PATCH webhook aliases, cage alias (already covered by cage_code).

Test plan

  • uv run pytest tests/test_api_parity.py tests/test_client.py tests/test_models.py132 passed, models.py 100%
  • ruff check . + ruff format --check clean
  • Integration/production cassettes need re-recording — ~32 stale cassettes were recorded against the old page=1 contracts request. Run TANGO_REFRESH_CASSETTES=true TANGO_API_KEY=<key> uv run pytest tests/integration/ tests/production/ (needs a prod API key).
  • X-Requests-Remaining header verification (deferred to a live smoke test)

…ixes)

Phase 1 (bug fixes):
- Contract model: drop dead fields (id, award_id, recipient_name, award_amount,
  awarding_agency, funding_agency); add real ContractListSerializer fields. Old
  fields kept Optional/None + deprecation note, to be removed in 2.0.0.
- list_contracts: stop sending page=1 to the cursor-only /api/contracts/.
- add list_otidv_awards (parity with Node).

Phase 2 (additive):
- budget accounts surface: list_budget_accounts, get_budget_account,
  get_budget_account_quarters, get_budget_account_recipients (+ BudgetAccount
  model + shape schema).
- singleton detail GETs: get_contract, get_contract_subawards,
  get_contract_transactions, get_forecast, get_grant, get_notice,
  get_opportunity, get_subaward.
- get_entity_budget_flows(uei).
- grant_id filter on list_grants.

Phase 3 (CI):
- re-enable lint.yml as a PR gate; conformance split into a non-blocking job.

Version bump to 1.1.0.

…tion

The list_contracts page=1 removal changed the recorded request URI, so 32
contract/edge-case cassettes no longer matched. Re-recorded against live API
(v4.6.9). Two expensive filter queries (awarding_agency, multi-param search)
504 at the gateway on re-record, so those two cassettes retain their prior
valid 200 response with only the stale `&page=1` stripped from the request URI.

CONTRACT_SCHEMA/IDV_SCHEMA reference the competition leaf as
"ContractOrIDVCompetition" but only "Competition" was registered in
EXPLICIT_SCHEMAS, so competition(extent_competed,...) nested selections on
contract/IDV shapes raised ShapeValidationError. Register the name as an alias
of COMPETITION_SCHEMA. Fixes tango-python#29 item 1.

Re-enabling lint.yml surfaced two pre-existing blockers unrelated to the API
sync: ~28 mypy errors that predate CI enforcement, and a conformance job that
fails because the private makegov/tango checkout needs an unconfigured
TANGO_API_REPO_ACCESS_TOKEN secret.

Keep ruff format + ruff check as hard gates (clean today). Make mypy advisory
(continue-on-error) pending a debt burn-down. Gate the conformance steps on the
token being present so the job skips cleanly (green) instead of failing red, and
becomes a real gate automatically once the secret exists.

Clears the 4 mypy errors the v1.1.0 branch introduced over main's baseline.
_parse_webhook_alert now emits str/dict/Literal values matching the model's
declared types (sparse payloads hydrate "" / {} instead of None); cli sample
payload cast to dict for assignment.

Completes the release flow for v1.1.0 (already merged via #31 with version
bumped to 1.1.0): dates the changelog section so the published release notes
match the tag. No code changes.
