# Per-tier drawing references for A3 cable-length estimation.
# Provisional, hand-authored 2026-04-30 — the agent did not capture exact drawing
# pages during its visual-tier estimation pass for MRT7. Future projects will
# populate this automatically once the playbook patch (Task 07 — scaled cable
# routes) lands.
#
# Each tier_id matches an entry in A3-route-lengths.yaml.
# For each tier, list the drawing(s) the visual estimation referenced. The
# review UI deep-links into these (file + page) so reviewers can eyeball the
# distances against the same source the agent used.
