malice
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>

"""Phase-0 purity guard: formatter modules must not call time directly.
|
|
|
|
Every file under meshai/notifications/formatters/ must route all time reads
|
|
through meshai.notifications.clock (the determinism seam). Direct calls to
|
|
datetime.now or time.time( inside a formatter break the monkeypatch contract.
|
|
|
|
This test is intentionally static (source-text check) so it catches new
|
|
formatters that forget the contract even before any test calls them.
