document the analysis contracts and correct the job-queue claim
The README's architecture diagram and stack list promised Redis + RQ. There is no such thing in this codebase: redis_url is a settings field nothing reads, rq is not a dependency, and the only worker is an asyncio poller over a Postgres job table. Describe what exists. API_CONTRACTS and KNOWN_LIMITATIONS gain the rules a reader needs to interpret a result: deterministic confidence-ranked matching, the precision/recall curve, the three flood-hazard cell populations, the sub-cell selection fallback, the whole-feature object count next to clipped area metrics, and the required manifest CRS. The new limitations are stated as limits rather than buried: raster analysis has no sub-cell precision, and the object count is not fractional. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
