PR 1.5 + PR 2 of the agentic briefing rollout. Extends the agentic
path to cover the morning/midday/afternoon check-in slots in addition
to the 4am compilation, and persists the full tool-call sequence
into the briefing conversation so chat follow-ups see the receipts.
run_slot_injection now honors the briefing_mode setting the same way
run_compilation does: agentic mode routes through run_agentic_briefing
with a check-in system prompt variant, legacy falls back automatically
if the new path returns empty. Signature changed from str to
(str, dict) to surface the agentic message list to the caller.
_agentic_system_prompt now takes the user's local-day window and
timezone, pre-computed by run_agentic_briefing, and embeds them in
the prompt. This eliminates a whole class of "wrong day" bugs that
would otherwise happen when the model tried to translate "today" into
ISO 8601 ranges without knowing the user's timezone.
briefing_scheduler._run_slot_for_user now calls _persist_agentic_messages
after each slot, which walks the agentic message list and stores
every intermediate assistant turn (with its tool calls and results
folded into the flat storage format the existing chat loader expects)
as a real message row. The synthetic "[Midday briefing update]"
user-role messages are no longer created — final prose is written
with metadata.briefing_slot so the UI can still identify it as a
scheduled entry. The agentic user-trigger ("Generate my morning
briefing…") is deliberately skipped so it doesn't recreate the same
fake-user-message problem we're trying to remove.
briefing_conversations.post_message now accepts tool_calls, matching
the schema the Message model already supports. This lets scheduled
briefings write structured tool-use history without reaching into
the model layer.
Net effect with briefing_mode="agentic" on:
- All four slots are grounded in tool results, no more hallucinated
events or tasks
- Chat follow-ups in the briefing conversation see morning's
list_events → [] receipt (and everything else), so "what meeting?"
gets an honest "nothing on the calendar" reply grounded in data
- No more fake [Briefing update] user messages in the chat scroll
Still to come (PR 3): UI polish — tool-call status row, inline cards
for list_events/list_tasks results, visual treatment for slot messages.
