Copyright 2026 Chelsea Kelly-Reif

This project is developed and maintained by Chelsea Kelly-Reif as an independent,
personal open-source project, on the author's own time and equipment.

It is not affiliated with, sponsored by, endorsed by, or a work product of any
employer or client of the author. It contains no employer- or client-proprietary
or confidential code, data, methods, or documentation.

Licensed under the Apache License, Version 2.0. See the LICENSE file for the full terms.

The Apache-2.0 grant covers this project's own work: code, prompts, eval suites,
documentation, and the reports generated from them. It does not cover the
transit-agency text this repository quotes, and it could not: those pages are
the agencies' copyrighted work, published on their own sites under their own
"all rights reserved" notices. This project holds no license to that text, so
it has none to pass on. Every place the text lands is carved out of the
Apache-2.0 grant, not only the first one:

  corpus/raw/                    fetched page snapshots, verbatim
  corpus/processed/*.md          the same pages, cleaned to markdown
  corpus/processed/chunks.jsonl  the same text, split into retrieval chunks
  corpus/snapshots/**            dated snapshots: raw bytes plus their chunks
  corpus/versions/*/chunks.jsonl chunk sets retained from earlier corpus versions
  evals/govchat/golden.jsonl     retrieved passages carried in each row's sources[]
  evals/plumbline/bundle/sources.jsonl
                                 the same documents, reshaped for the second-harness audit
  evals/calibration/judge_label_packet_2026-07-11.md
                                 passages quoted in full for human judge labeling
  EVALS.md, docs/eval-report.*   short passage excerpts inside failure traces

That is roughly 1.5 MB of other people's writing. Source URLs, fetch dates, and
each agency's own terms-of-use or copyright page (where one exists) are recorded
in `corpus/manifest.yaml`. `corpus/LICENSE-NOTE.md` says in plain English what a
downstream reader may and may not assume about this material. For current fare
policy, the agencies' own sites are the authoritative source; this repository is
a dated snapshot kept so an evaluation can be re-run against what it was scored
on.
