v0.9.0

Added

• P4 Wave K2b (H183) — the translator-first Sanskrit inflection lookup
  UI, the frontend half of the drastically-improved Cologne inflection tool.
  Executor: Opus 4.8 (claude-opus-4-8).
  • Svelte 5 + Vite app (ui/)
    building into docs/inflect/,
    served by the existing Pages deploy at gasyoun.github.io/kosha/inflect/
    (62 kB JS bundle). Four features (H183 K2b-3, roadmap Wave K3 folded in):
    stem → paradigm (auto-detect input → SLP1, Devanagari-default
    case×number / verb grids with an IAST/SLP1 toggle), paste-anything
    reverse analysis (wraps /analyze, shows resolved_by provenance),
    autocomplete (prefix range-seek over the shared 323k lemmas.json,
    live transliteration), and dictionary cross-links (every stem links to
    its in-app MW/PWG/AP90 entry; the entry has a "show all forms" control back
    to the paradigm — two silos, one tool).
  • Data backend is "both" (K2b-2, ui/src/lib/datasource.js):
    static pre-generated JSON by default (works with no live server —
    RISKS.md R1/R5/R12-clean), and the live FastAPI /api/v1/… when
    window.KOSHA_API is set. Stage-3 vidyut segmentation degrades honestly to
    segmentation_available:false in the static tier (the live-API path
    resolves it).
  • New GET /api/v1/paradigm/{lemma} endpoint + shared
    app/paradigm.py
    grouping module, and
    scripts/build_paradigms.py
    emitting parity-locked static paradigm + reverse-index shards
    (--demo committed, --all deployed by MG out-of-band per A3). Bridged
    stems fold (Bagavant→Bagavat).
  • Auto-detect input (Devanagari/IAST/SLP1) via the vendored sanskrit-util
    JS package (SHARED_CODE.md family #1 — no new transcoder); Devanagari
    rendering uses slp1_to_devanagari (composes matras/conjuncts) not the
    naive iast_to_devanagari.
  • Tests: 6 new pytest (tests/test_paradigms.py, endpoint + static-shard
    byte-parity) → 167 passed; 17 vitest (translit auto-detect, token
    parity, prefix seek, static data-path integration, full App e2e).
  • Data caveat surfaced verbatim (D3): the Cologne m_a ṇatva bug
    (MWinflect#6) is shown as-is, not silently "fixed" in the frontend.

Notes

• Roadmap Wave K3 folded into K2b per MG 05-07-2026 — the inflection roadmap
  now owes only Wave E1 (dual-engine vidyut comparison).
• Pages tier re-measured: docs/inflect/ = 2.0 MB (app + committed demo data);
  total tier ~404 MB, ~60% headroom under the 1 GB soft limit unchanged.
