f06bf3ce92Foundation for making all hazard formatting+gating source-agnostic. ZERO behavior change — the formatter/decider registries are empty (get_formatter/ get_decider return None → existing precomposed/Mode-B path preserved), and the shadow comparator is off unless MESHAI_SHADOW_CATEGORIES is set. - notifications/formatters/ (registry+dispatch with family fallback), gating/ (GateResult + deferred-commit contract), both empty registries. - notifications/clock.py determinism seam; route wfigs/quake/nws gating time reads through it (identical values) so goldens can freeze time. - formatters/_budget.py = copy of central/budget.py; central/budget.py is now a re-export shim (import-smoke test guards it). - compose_mesh_message consults the registry first (verbatim, no Mode-B re-cap), falls back to legacy; _resolve_budget injects per-category budget. - notifications/shadow.py + two DRY-RUN hooks (consumer._normalize, dispatcher render): compute the new result and diff-log SHADOW_MISMATCH JSONL, but NEVER commit/emit/write tables and always broadcast the OLD result. Inert by default. - tests/harness (pinned_time/pinned_tz, byte-golden, gate-sequence) + scripts/capture_fixtures.py (ephemeral read-only NATS capture); tzdata pinned. Tests: +60 (18 scaffold + 42 harness/shadow); 0 new failures (34 baseline). Co-authored-by: Matt Johnson <mj@k7zvx.com> Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""Pytest fixture isolation for meshai persistence (v0.6-2).
|
|
|
|
Before v0.6-2 the dispatcher held all state in instance memory, so tests
|
|
that constructed `Dispatcher(...)` were inert w.r.t. SQLite. v0.6-2 made
|
|
`Dispatcher.__init__` read/restore from the persistence layer, which by
|
|
default points at `/data/meshai.sqlite`. Without isolation every test
|
|
would now read+write production state, polluting across tests and across
|
|
pytest invocations.
|
|
|
|
This autouse fixture redirects `MESHAI_DB_PATH` to a per-test tmp file
|
|
and clears the persistence-layer threading.local caches around each test.
|
|
Existing tests that don't reference any fixture get isolation for free;
|
|
tests that explicitly use a `db_path` (or similar) fixture can still
|
|
override the env var inside their own fixture body -- last setenv wins.
|
|
|
|
Phase-0 addition: a session-scoped TZ fixture validates that
|
|
America/Boise resolves via zoneinfo, exercising the tzdata guard needed
|
|
in CI environments. The fixture saves and restores the original TZ so
|
|
that existing tests running with naive datetimes are unaffected.
