…-v2, merit-v2)
Both adapters emit the catchments+snap bbox as a struct {xmin,ymin,xmax,ymax} (StructArray.from_arrays + leaf row-group stats + GeoParquet covering); FORMAT_VERSION 0.3.0; snap manifest -> hfx.aux.snap.v2; graph stays flat. Feeds the s13 GRIT re-host.

…r accuracy (#10) * docs(release): repoint canonical GRIT dataset URL to grit/hfx-v0.3.0 The HFX v0.3.0 (GeoParquet bbox-covering) GRIT dataset is published to a new additive R2 prefix grit/hfx-v0.3.0/. The legacy grit/2.0.0/ dataset stays live as the format_version 0.2.1 dataset for clients pinned to pyshed 0.2.4. - upload-r2-rehost.sh: TARGET_PREFIX -> grit/hfx-v0.3.0/ (additive publish, not in-place overwrite); derived scope guard becomes ^grit/hfx-v0.3.0/; header, comment, and FATAL-message prose updated. - README.md / hosting/README.md / adapters: canonical manifest + object URLs repointed; hosted-dataset format_version prose corrected to 0.3.0. - rehost runbook: post-fire manifest curl check repointed to the new prefix. * docs(adapters): correct grit-v2 snap aux to v2 and adapter table to format_version 0.3.0 Both grit-v2 and merit-v2 emit FORMAT_VERSION 0.3.0 and hfx.aux.snap.v2 (PR #8); the READMEs still claimed snap.v1 / format_version 0.2.1. * docs(hosting): fix 0.3.0 GRIT docs for additive new prefix - adapters/merit-v2/README: align to FORMAT_VERSION 0.3.0 / hfx.aux.snap.v2 (mirrors the grit-v2 README fix; build_adapter.py already emits these) - hosting/grit-hfx-v0.3.0/README: new 0.3.0 dataset README for the additive grit/hfx-v0.3.0/ prefix (base URL, format_version, snap.v2, bbox covering) - hosting/grit-2.0.0-rehost-v0.3.0/README: rewrite runbook for the additive new-prefix model (OD-8 resolved, publish-not-overwrite, empty pre-state, attribution publish step, existence post-checks) * docs(readme): drop exact legacy byte count from the GRIT 0.3.0 dataset table The 43,361,501,501-byte figure is the measured size of the legacy 0.2.1 build; the 0.3.0 covering dataset (added bbox struct + leaf stats) will differ. Keep the approximate ~43 GB, matching hosting/grit-hfx-v0.3.0/README.md.

Milestone alden-feedback s08. Both reference adapters (grit-v2, merit-v2) emit the HFX 0.3.0 struct bbox covering for catchments (non-nullable) + snap (nullable struct, non-nullable leaves), FORMAT_VERSION 0.3.0, snap -> hfx.aux.snap.v2; graph stays flat. Verified by building a sample and validating with the v0.3.0 validator (--strict exit 0) + verify_struct_leaf_stats.py. Pre-existing grit-v2 _write_readme REGIONS bug left untouched (flagged for s13). Plan: planning/milestone-alden-feedback/s08/plan.md.
