LIA

Reliability release: wave 1 of a full-codebase audit — 14 confirmed, surgical, single-function fixes (each with a regression test written red-first) plus a hardening pass. No new user feature, no DB schema change, no migration.

Fixed — Connected services

• Apple Calendar events now honor the requested timezone (a "10:00 Europe/Paris" event no longer lands at 10:00 UTC; covers create + update).
• Microsoft Calendar search tolerates apostrophes (l'anniversaire no longer breaks the OData filter → 400).
• Google Tasks "list task lists" works again (a missing () raised AttributeError on every call).
• Route maps render correctly (a polyline-encoder operator-precedence bug corrupted multi-segment geometry).

Fixed — Assistant behavior

• Ambiguous Gmail labels now ask which one instead of a generic error (KeyError).
• Stopping a ReAct exploration (closing the conversation) actually cancels it (CancelledError was swallowed as a tool error).
• Connector "not activated" messages are localized in all 6 languages (no more inline French in LLM-facing scaffolding).

Security & configuration

• /users/search/by-email is superuser-only (account-enumeration surface closed).
• Planner budget/steps .env overrides are honored (one path always served a hardcoded 50$/50).
• Two previously-hardcoded values become .env-configurable: metrics sync interval, MCP ReAct step timeout.

Reliability & dead code

• Registry LRU eviction no longer crashes on mixed timestamp forms in long conversations.
• QueryIntelligence field silently dropped on every HITL resume restored (guarded by a full round-trip test).
• LLM capability check unified (tool_calling → tools); web client no longer leaks an abort timer per request.
• Dead never-wired per-node message-windowing subsystem removed (ADR-094).

Test infrastructure

• The long-silently-rotted tests/agents suite (83 stale failures, never gated) is rehabilitated to green (1069 tests) and wired into CI.
• A value-blind-test scanner (scripts/analyze_value_blind_tests.py) closes the class of gap the polyline bug exposed — zero fully value-blind files remain.

Quality: Ruff / Black / MyPy strict clean; backend 8572 unit + 1069 agents green, frontend 120 green; i18n parity OK; Docker healthy. Full details in CHANGELOG.md.
