 ## [Unreleased]
 
+### Fixed
+- `_parse_webhook_alert`: aligned the parser output with the `WebhookAlert`
+  type contract. Sparse server payloads now hydrate `query_type` and `filters`
+  as `""` / `{}` (matching their declared non-null types) rather than `None`,
+  and `status` is typed as the `Literal["active", "paused"]` the model promises.
+  Clears the four type-check errors this introduced; no change for full payloads.
+- `Contract` model: removed dead fields (`id`, `award_id`, `recipient_name`,
+  `award_amount`, `awarding_agency`, `funding_agency`) and added the real API
+  fields (`key`, `piid`, `obligated`, `total_contract_value`,
+  `base_and_exercised_options_value`, `awarding_office`, `funding_office`,
+  `naics_code`, `psc_code`, `set_aside`, `solicitation_identifier`,
+  `parent_award`, `legislative_mandates`, `subawards_summary`,
+  `place_of_performance`). The deprecated fields remain declared with `None`
+  defaults for one minor cycle (they never returned data) and will be removed
+  in `2.0.0`. New `OrganizationOfficePayload` dataclass for the office fields.
+  (`Contract` is a documentation-only dataclass — not instantiated or exported
+  — so there is no runtime impact.)
+- `list_contracts`: no longer sends `page=1` to the cursor-only `/api/contracts/`
+  endpoint. When no cursor is supplied, neither `page` nor `cursor` is sent and
+  the API returns the first page by default.
+- Shape validation: registered the `ContractOrIDVCompetition` nested schema
+  (alias of `Competition`) so nested selections like
+  `competition(extent_competed,number_of_offers_received)` on contract / IDV
+  shapes validate instead of raising `ShapeValidationError`.
+
+### Added
+- Budget accounts surface (tango v4.6.8): `list_budget_accounts`,
+  `get_budget_account`, `get_budget_account_quarters`,
+  `get_budget_account_recipients`. New `BudgetAccount` dataclass exported from
+  the top-level package, plus `ShapeConfig.BUDGET_ACCOUNTS_MINIMAL`.
+- 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)` for `/api/entities/{uei}/budget-flows/`.
+- `list_otidv_awards(key)` for `/api/otidvs/{key}/awards/` (parity with Node).
+- `grant_id` filter kwarg on `list_grants` (supports multi-value OR via `|`).
+
+### CI
+- Re-enabled `lint.yml` as a PR + push-to-main gate. `ruff format` and
+  `ruff check` are hard gates; `mypy` runs advisory (continue-on-error) pending
+  burn-down of ~28 pre-existing type errors. The filter/shape conformance check
+  is a separate job that skips cleanly until a `TANGO_API_REPO_ACCESS_TOKEN`
+  secret for the private manifest repo is configured, at which point it becomes
+  a hard gate.
