Eric Wagoner 4bf7481f9b Extract reports unidentifiable boxes for human retakes
The vision prompt now returns {titles, unidentified}: boxes that look
like games but can't be confidently titled are reported (location
relative to identified neighbors, partial text, art notes) instead of
silently omitted. They land in data/unidentified.json keyed by photo,
and the end-of-run summary lists them — plus low-confidence reads —
with instructions to retake a closer photo and re-run. New --force flag
re-extracts everything; pre-feature raw caches (bare arrays) still
parse. Live run on IMG_4499 confirmed the flow and the low-confidence
list correctly flags the known "Hebarceos" misread.

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project
`bggpipe` — a resumable, idempotent CLI pipeline: shelf photos → Claude vision title + edition-cue extraction → BoardGameGeek ID and version matching → human review → collection diff → upload to BGG via Playwright → metadata enrichment (`games.json`). Full design: @bgg-shelf-pipeline-spec.md. **The repo is greenfield — no code exists yet.** Follow the spec's "Suggested Build Order" when scaffolding; re-run `/init` once code exists.
## Stack (decided, not yet scaffolded)
- Python 3.12+, deps via **uv** (`uv add`, `uv run`), CLI framework **typer**, tests **pytest**, lint/format **ruff**.
- Browser automation: **Playwright** (not Selenium). Needs `uv run playwright install chromium` after install.
- Vision: Anthropic API, latest Sonnet model.
## Hard rules (from spec — never violate)
- **≤1 request every 2 seconds** to any BGG endpoint; jittered backoff on 429/503. Upload stage: 24 s randomized delay between games.
- **Credentials never touch disk or logs.** `ANTHROPIC_API_KEY`, `BGG_USERNAME`, `BGG_PASSWORD`, `BGG_API_TOKEN` come from env vars only. Playwright storage state is credential-adjacent — keep it gitignored.
- **The XML API requires a registered app token** (`Authorization: Bearer`, from `BGG_API_TOKEN`) — unregistered requests get 401. Until Eric's registration at boardgamegeek.com/applications is approved, tests run on the stub fixtures in `tests/fixtures/bgg_cache/`; re-record them with `scripts/record_fixtures.py` once the token exists.
- **Every stage is idempotent and resumable** — killing mid-run and restarting must lose no work; re-runs skip already-processed items.
- Use only the XML API2 and the public website — no undocumented BGG endpoints (BGG tightened access policies in 2025).
- BGG has **no write API**: writes drive the real website with a logged-in Playwright session.
## Domain gotchas
- Base game vs. expansion vs. new edition is the top failure mode — bias matching toward `ambiguous` over auto-match ("Wingspan Europe" must not match base Wingspan).
- Editions/versions matter: Eric owns multiple editions of some games — each is a separate collection entry (keyed by `collid` on BGG). Never guess a version: no legible cues → `version_unknown` and a version-less collection entry.
- Normalize titles (casefold, strip punctuation/articles, special chars like é/&/:) identically on both sides of a match; dedupe across photos but keep `source_photos` provenance.
- Detailed BGG API behavior (202 queueing, collection-endpoint quirks, endpoints): use the `bgg-api` skill. **If the spec's BGG behavior changes, update the `bgg-api` skill to match** — they must not drift.
## Git
- Remote is self-hosted Gitea 1.26 (`git.kestrelsnest.social`), **not GitHub**`gh` CLI does not work here.
- Commit `data/matches.csv`, `data/to_add.csv`, `data/upload_log.csv`, `data/titles.json`, `data/unidentified.json`, `data/games.json`. Never commit `data/bgg_cache/`, `photos/`, Playwright storage state, or `.env`.
