CTO — Bugfix Task: Appointment detection priority (Saturday / morning case)

We’ve just tested a real renewal conversation and found that the URE is not treating clear appointment intent correctly.

Conversation example (conv_id: 48d710fa-d45b-4552-93e0-eff71f60c7eb):

LIA opener (EOT_12_USED):

“Would you have time to pop in one day soon so we can look at your options together?”

Customer:

“Hi I could do Saturday ?”

LIA response:

template_key = "T1_GENERAL"

mode = "T1_GENERAL"

asks again “What day is usually easiest for you to pop in?”

Customer:

“How about in the morning ?”

LIA response:

template_key = "SMALL_TALK"

mode = "SMALL_TALK"

again “What day normally works best for you to pop in?”

Expected behaviour (from the LIA brief):

Messages containing a day word (monday…sunday, tomorrow, this weekend, next week) in the context of visiting should be treated as T3_APPOINTMENT (vague day).

Messages containing only time-of-day words (morning, afternoon, evening) in reply to “what day/time works” should go into the “vague time” appointment branch, not SMALL_TALK.

Please implement:

In app/lia_ure.py, ensure there is a dedicated detection step for appointment intent:

e.g. is_appointment_intent(message_text) and/or detect_day_from_text(...), detect_time_of_day(...).

Change the classification / branch order so that:

Appointment checks run before T1_GENERAL and SMALL_TALK.

For a message like “I could do Saturday ?” after an invite, we end up with:

tier = T3_APPOINTMENT

last_reply_type = "APPOINTMENT_VAGUE_DAY" (or similar)

For “How about in the morning ?” we either:

if day is already stored in state → confirm day + morning slot options, or

if no day is stored → treat as vague time, ask “which day in the morning works best?”.

Add explicit tests for these strings in the URE tests:

"Hi I could do Saturday ?" → classified as T3_APPOINTMENT, response offering two time slots on Saturday.

"How about in the morning ?" following that → either confirm or ask for a day, but must NOT fall into T1_GENERAL or SMALL_TALK.

Re-run tests and confirm that for conv 48d710fa-... the next inbound “Saturday” style message would now hit the appointment branch.
