# Debug info OFF for dev and test builds — the single biggest lever on build
# cost. Measured across this fleet 2026-08-22: 22 GB / ~40 min with debug info
# vs 4.4 GB / ~10 min without, on the same tree. `[profile.test]` inherits from
# `dev`, so this one entry covers `cargo build` and `cargo test` alike.
#
# It belongs in the manifest rather than in each session's environment: carried
# as `CARGO_PROFILE_*` env vars it only helps a session that remembers, and a
# fresh clone or a CI runner gets the expensive build. lance-graph (#962) and
# MedCare-rs already set this default.
#
# Given up: line numbers in panic backtraces. `debug = "line-tables-only"`
# restores them cheaply when a debugging session needs them — a deliberate
# temporary edit, not a reason to keep the default expensive.
