Foundation for the cost estimates and partial-stall detection that Phase 2 will surface. No consumers yet — this PR just lays the table, the seed rows, and the lookup helper so subsequent UI work has estimates available without a per-ZIM benchmark. ## What lands - New table `kb_ratio_registry` (pattern, chunks_per_mb, sample_count, notes). Migration creates and seeds heuristic defaults from the RFC appendix: devdocs (1100/MB), Wikipedia variants (270/MB), iFixit (50/MB), Stack Exchange Q&A (200/MB), video-only ZIMs (0), plus a catch-all fallback at 100/MB. - `KbRatioRegistry` model with static `lookup()` and `estimateChunks()`. - Pure helper `kb_ratio_lookup.ts` doing longest-prefix-match — a specific entry (`wikipedia_en_simple_`) overrides a broader one (`wikipedia_en_`). 9 unit tests covering the lookup boundary. - `sample_count` starts at 0 (heuristic seed) and is reserved for Phase 4 self-calibration to increment as observed ZIMs update each row. ## Not in scope - Self-calibration on successful ingestion (Phase 4) - UI consumers — Warning B (partial-embed stall) and the storage budget meter / time estimates land in Phase 2. ## Tested - Type-check clean - 9 unit tests pass for `findChunksPerMb` and `estimateChunkCount` - Migration applied on NOMAD3 via hot-patch; 9 seed rows verified in DB |
