VOS LUNETTES, OPT-IN

Les facettes

Les lentilles de lecture : elles réordonnent l'arrivée, jamais le classement public.

Date: 2026-09-16 Method id: life-facets-v0.1 approaches-reorder-only Code: scripts/life_facets.py

Declared life lenses a resident may turn on. They reorder Approaches on Arrival only.

They do not:

change latest_ranked.json or rank_score
change w_geo / w_recency / w_tension / w_impact (w_impact stays gated at 0)
filter Approaches away
invent a For You feed
apply without opt-in (default = issues store order)

For each Approach and each active facet F:

score += F.topic_weight   if approach.topic ∈ F.topics
score += F.unit_weight    if any approach unit.kind ∈ F.unit_kinds

Sort Approaches by (-score, store_index). Ties keep store order. Same issue_id set before and after.

id	Label	Topics matched	Unit kinds	topic_weight	unit_weight
renter	Renter	housing	price, housing_count	1.0	0.35
transit	Transit	transport	—	1.0	0.0
energy	Energy	energy/hydro, energy, hydro	price	1.0	0.35
civic	Civic	law	bylaw_id	1.0	0.35
health	Health	health	—	1.0	0.0

Topics come from proposed enrich/issue topic tags already on disk. Units come from proposed impact units already on the Approach.

UI: Arrival “Life facets (opt-in)” — off until the resident toggles.
Preference may live in localStorage (vigie_facets_v1) on that device only.
Clear facets → store order returns.
Morning ambient digest stays store order (shared pulse twin). Facets are a local Arrival lens.
