 - Energy site events (`teslemetry_stream/energysite.py`) are shaped differently from vehicle signals: `live_status`/`site_info` are flat top-level envelopes (`{createdAt, site_id, isCache?, live_status|site_info}`), not nested under `data`, and the payload is a full opaque document rather than a field delta - there is no per-field config to enable, the server auto-polls subscribed sites. Contract source: Teslemetry/api PR 310 (`src/routes/sse/index.ts`, `liveStatusSchema.ts`, `siteInfoSchema.ts`), flag-gated server-side as of this writing - `tests/test_energysite_events.py` fixtures mirror that PR's schemas.
 - `energy_totals` (Teslemetry/api PR 316, trimmed by PR 321) is shaped differently again: the site id rides the `id` field, not `site_id` - filter on `id` and `totals`, not `site_id`. It carries a compact cumulative `totals` object (`EnergyHistoryTotals` in `const.py`) instead of a document, fires only when the server's periodic `calendar_history` poll detects a change (silence is not staleness), and has no snapshot-on-connect delivery. As of PR 321 the wire payload is trimmed to `id`/`createdAt`/`totals` plus `isCache` only when true (`product_type`/`topic`/`url` were dropped as redundant with the event's own topic name and site id); `Key.PRODUCT_TYPE`/`Key.TOPIC`/`Key.URL` in `const.py` remain defined for other event kinds but are no longer part of the energy_totals filter.
 - `site_info` events no longer carry `tariff_content`/`tariff_content_v2` (Teslemetry/api PR 318); the V2 tariff is its own `tariff_content_v2` event/listener (`listen_TariffContentV2`), same envelope shape as `site_info`, with a `None` body meaning an explicit server-side removal rather than "not received yet". Both share the same silence-means-no-change contract - freshness lives in REST, never in event cadence. There is deliberately no library helper recombining `site_info` and `tariff_content_v2` into one document - that would only ever cover the V2 tariff (legacy V1 `tariff_content` has no SSE topic and stays REST-only by design), so it can't actually promise the whole REST-shaped document; a consumer wanting both tariffs together should use the REST site_info endpoint.
-- Releases (tag `v*.*.*`) go through `.github/workflows/release.yml`, a reusable `workflow_call` gate: `lint` + the full `test` python-version matrix (mirrors `ci.yml`) must pass on the exact release SHA before `build` (single Python, build+twine) runs, and only then do the `pypi` environment's protection rules (and its trusted-publishing OIDC) allow `publish-to-pypi`; `python-publish.yml` just supplies the tag trigger and calls it. The `pypi` GitHub environment itself (required reviewers, deployment branches) is admin-configured outside this repo's files.
+- Releases (tag `v*.*.*`) go through `.github/workflows/release.yml` directly - it's the sole top-level workflow, triggered on the tag push: `lint` + the full `test` python-version matrix (mirrors `ci.yml`) must pass on the exact release SHA before `build` (single Python, build+twine) runs, and only then do the `pypi` environment's protection rules (and its trusted-publishing OIDC) allow `publish-to-pypi`. It must stay a top-level workflow, not a `workflow_call` reusable one - PyPI's trusted publisher is configured for the `release.yml` + `pypi` environment identity, and a reusable-workflow caller signs PEP 740 attestations under the caller's identity instead, which that publisher check rejects. The `pypi` GitHub environment itself (required reviewers, deployment branches) is admin-configured outside this repo's files.
 - `TeslemetryStream(topics=...)` (Teslemetry/api PR 319) is an optional exact SSE wire-event allowlist sent as the connection's `topics` query param; `SseTopic` in `const.py` is the closed set the server recognizes (must stay in sync with the api's `SSE_TOPICS`), and `SSE_VEHICLE_TOPICS`/`SSE_ENERGY_TOPICS`/`SSE_ALL_TOPICS` are client-side presets - flat per-product-kind lists of exact wire names, deliberately not further split by whether a topic happens to have a connect-time snapshot server-side; that's upstream server behavior, not something this library encodes. Omitting `topics` (`None`) is legacy-all forever - every applicable event delivered unfiltered - and existing callers that never pass it are unaffected. An explicitly empty iterable is rejected with `ValueError` at construction time rather than silently falling back to legacy-all - "no topics" must not mean "all topics", mirroring the server's own 400 on an empty `topics` value. A bare `str`/`SseTopic` is accepted as a single topic rather than iterated character-by-character - `topics` type-checks `str | Iterable[str] | None` precisely because a lone string also satisfies `Iterable[str]`, the classic footgun. `tests/test_sse_topics.py` covers the tariff listener, its null-removal signal, the `topics` param's URL construction, the empty-iterable rejection, and the bare-string/bare-`SseTopic` case.
