Backend follow-up to INV-UI9 (X6 §"אודיט-נלווה"): make server-side
datetimes explicit so flipping the container to TZ=Asia/Jerusalem cannot
silently skew stored or displayed timestamps. Storage stays UTC; human
display is Israel time.
- audit.py: naive datetime.utcnow() → datetime.now(timezone.utc) for the
TIMESTAMPTZ audit_log.created_at. Under TZ=Asia/Jerusalem the naive UTC
wall-clock would be read as Israel-local and stored ~3h off. (§6: no
silent skew.)
- calibrate_effort.py: _ts() report stamp now Israel-time via
ZoneInfo("Asia/Jerusalem") with a filename-safe "-IL" suffix (script runs
on the UTC host); added a labeled "שעון ישראל" line to the report header
so the chair-facing timestamp is unambiguous. --self-test still ALL PASS.
- research_md.py: display fields made deterministic Israel-tz —
update_chair_position timestamp (datetime.now(IL_TZ)) and parse() mtime
(datetime.fromtimestamp(..., tz=IL_TZ)) — correct regardless of process TZ.
Left intentionally Israel-local-day date.today()/year-cutoff call sites
untouched (drafting/party_claims_summary/block_writer/court_fetch_supreme)
— a Jerusalem committee wants the Israel calendar day; they resolve
correctly once TZ flips.
Invariants: INV-UI9 (store-UTC / display-Israel, server side); §6
(timezone-aware datetimes, no silent ~3h skew).
