From 31f5bf816c03e66296cac58c385348b081570ff5 Mon Sep 17 00:00:00 2001 From: Harsh Pandhe Date: Fri, 22 May 2026 20:30:19 +0530 Subject: [PATCH] feat(tagline): "15s vs 3-4 weeks" benchmark + comparison page New `ropeway tagline` command times the optimizer end-to-end on six representative corridors (Andean urban, alpine 3S, funitel, urban gondola, tourist tram, pulsed gondola), then frames the wall-clock against a 3-week / 120-engineer-hour / ~$60k feasibility-study baseline per corridor and writes a JSON manifest + markdown comparison page. Headline on the default pack: six corridors, 100% feasible, ~4s total wall-clock, ~626 000x speedup vs the manual baseline. Outputs land at docs/tagline/tagline.{json,md}; the page is wired into the mkdocs nav as "15s vs 3-4 weeks". README gets the speedup table. 7 new tests cover row math, summary aggregation, JSON round-trip, markdown shape, file emission, and an end-to-end optimizer smoke. Full suite: 435 passing. --- CHANGELOG.md | 15 ++ README.md | 16 +++ docs/PHASE_PLAN.md | 4 +- docs/tagline/tagline.json | 64 +++++++++ docs/tagline/tagline.md | 33 +++++ mkdocs.yml | 1 + src/ropeway/benchmark_tagline.py | 227 +++++++++++++++++++++++++++++++ src/ropeway/cli.py | 28 ++++ tests/test_benchmark_tagline.py | 96 +++++++++++++ 9 files changed, 483 insertions(+), 1 deletion(-) create mode 100644 docs/tagline/tagline.json create mode 100644 docs/tagline/tagline.md create mode 100644 src/ropeway/benchmark_tagline.py create mode 100644 tests/test_benchmark_tagline.py diff --git a/CHANGELOG.md b/CHANGELOG.md index a472e37..c6877e2 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -27,6 +27,21 @@ a documentation / housekeeping commit on `main`.
