Read-only vehicle morning summary

Contract: tessie-morning-brief-consumer-v1

Host owner: jbaruch/nanoclaw src/host-plugins/tessie-brief/. Read the full installed skills/host-contracts/references/tessie-morning-brief.md before source or runtime maintenance. tessie_brief_request is a separate schema1 fixed summary operation, with no caller route/date/vehicle/role/enrollment fields. The actual unique Telegram Main source and protected Tessie owner are required. Current dynamic non-archived vehicles are resolved by the existing broker. No consumer file, output, environment or successful estimate grants authority.

The fixed script loads the same-provider tessie-charge/scripts/charge_ipc.py, which loads the co-shipped native tessie-ops transport. Installed prefixed skills never search an unprefixed neighbor. Missing or incomplete closure refuses; there is no direct HTTP or local policy fallback. One request is submitted, with no automatic retry. The host owns cached Tessie reads, native home clock and today's maintained drive metadata/energy estimation. It never wakes a car, creates a command/notice intent, changes enrollment, registers a cadence or sends a vehicle notice. IPC request/reply transport files are the sole consumer writes.

The script returns exact {wake_agent:false,data}. Data schema1 contains schema_version, home day, home_timezone, UTC observed_at, checked_vehicles, coverage, uncovered_sources, complete vehicles, and literal deterministic lines. Each vehicle has exactly alias, alerts and unknown_checks. Each alert has kind and the corresponding bounded detail object described by brief_ipc.py. The script validates the full response before emitting any line. It carries no VIN, precise location, saved-home label, Calendar identity/body, credential or provider error prose.

One line combines every proved requested condition for one affected vehicle. No line is emitted for a clear or unknown check. Stored overnight observations are explicitly labelled as such; their bounded temporal coverage cannot prove unobservable events between samples. Today-energy estimates remain conditional, using the same measured capacity, consumption, allowances and forecast as #2. Tire warnings name their positions. Current warning flags never mean that an available software update is an alert.

Generic still-open firmware status is not exposed by the documented Tessie history API. uncovered_sources:["firmware_active_status"] and partial coverage remain explicit. Generated historical firmware entries are never relabelled open. The supported positive current vehicle warning is the native cached not_enough_power_to_heat flag. No new telemetry subscription, approval ledger or persistent alert store exists. This capability limitation keeps the original issue acceptance open; source tests do not establish complete firmware coverage.

Publish/install the Host contract, merge/deploy the real Core producer, then publish this consumer and its optional Admin gather integration. The host checks both declared installed provider contracts and complete regular transport files. Missing/newer/unsupported contracts hold without a provider fallback. Root owns native installed-byte, identity, asleep-cache/no-wake and normal-brief acceptance. No live task, vehicle action or cadence is activated by this source release.

Schema1 admits a paired null day/home_timezone only for missing or invalid protected native home. Both dependent checks remain unknown for every vehicle; proved independent health lines survive. No fallback timezone is supplied. Half-null or falsely complete dependent coverage refuses. Host data remains bounded at 128 KiB; the complete fixed rendered envelope is bounded at 256 KiB.

Brief aliases are nonempty and bounded at 100 UTF-16 code units (at most 300 UTF-8 bytes), matching native admission and the saved reader. Oversized or unsafe upstream aliases hold the complete summary; never truncate or drop a vehicle. Brief-only VIN-free ordinal labels do not change native selectors.
