#[0.2.0] - unreleased

#Added

  • Languages: Bhojpuri, Marathi, Bengali, Tamil, Telugu, Gujarati, Kannada, Malayalam, Punjabi and Odia, each in its own script and in Latin letters, plus number words, units, request words and "and" for each. Machine-drafted; not yet reviewed by native speakers (see docs/lexicon.md).
  • Grocery lexicon grown from about 30 to 130 products; mock sellers now sell them, so search and basket work in the demo.
  • Parser: digits of all Indian scripts, nukta removal in all scripts, zero-width joiner removal, Malayalam chillu normalisation, digit+letter splitting ("2கிலோ"), danda separators, variants stored without stopwords, longest matching variant wins.
  • Tests for each language, script digits, number words, units, multi-word-beats-single-word, look-alike products, and a whole-file check that no variant belongs to two products.
  • Sign-in: OAuth Direct Sign-In with PKCE, private_key_jwt client assertions (ES256, PS384), refresh, revocation, scopes and scope hints, saved addresses, account-owned orders and conversations, sign-in events in conversations (8.11).
  • Poppy section 9: excluded-tasks document and feedback endpoint.
  • Server-sent events for conversation events, with Last-Event-ID.
  • PS384 delegations; RSA JWK thumbprints.
  • Storage: SQLite via node:sqlite or bounded memory, with caps; operations, Sessions, orders and conversations survive restarts.
  • ONDC: signed v2 registry lookups, onboarding endpoints, key generation and a subscribe template.
  • ESLint, Dockerfile, docker compose, production entry point (npm run serve), CI jobs for lint, the official validator and Docker.
  • Hindi README.

#Changed

  • Phonetic key no longer folds e into i, so "tel" (oil) and "til" (sesame) are different words.
  • The makhana test now uses a product that is really unknown ("dragon fruit"), since makhana is in the lexicon.
  • Conversations are open to agents without the Operations extension; only ordering needs it (spec 3.3, found by the official validator).
  • Feedback requires a verified Session header.
  • An unknown cursor is invalid_cursor (400); cursor_expired (410) is for dropped events (8.13).

#[0.1.0] - unreleased

#Added

  • Personal Agent Protocol draft 0.3: discovery, Session header verification with delegated keys, conversations (events, cursors, long polling, idempotent message IDs, handoff, close).
  • Operations extension v2 approval gate for orders and cancellations: exact revisions, at most once, 503 when the outcome is unknown.
  • Beckn buyer app: Ed25519 and BLAKE2b-512 signing, registry lookups, search fan-out, select, init, confirm, status and cancel.
  • Hinglish and Hindi request parsing with a data-driven lexicon; basket builder.
  • Grocery (RET10) and starter food (RET11) domain packs.
  • Mock network: registry, Beckn gateway and three Varanasi sellers; reference Personal Agent; demo.
  • Tests, CI, documentation and diagrams.
