3+## v0.4.0
4+
5+### Panproto-native architecture
6+
7+Every data layer is now powered by panproto — schemas, morphisms, field transforms, and instance parsing replace all hand-written string munging.
8+
9+**Schema-driven record processing**
10+- All 130 Lexicon files (56 Cospan + 74 Tangled) parsed via `panproto_protocols::atproto::parse_lexicon()`
11+- Every incoming Jetstream record goes through `parse_json()` → `lift_wtype_sigma()` → `to_json()` → `serde_json::from_value()`
12+- DB projection field transforms (AT-URI decomposition, field renames, counter defaults, nested extraction) defined as panproto `FieldTransform` expressions (`ComputeField`, `RenameField`, `AddField`, `DropField`, `PathTransform`)
13+- 19 Cospan DB projections compiled at codegen time via `panproto_mig::compile()`
14+
15+**Tangled interop via panproto morphisms**
16+- 17 Tangled→Cospan morphisms defined as explicit `Migration` vertex/edge maps
17+- Compiled at codegen time, serialized to msgpack, loaded at appview startup
18+- Applied at runtime via `lift_wtype_sigma()` — no string template code generation
19+- Added `scripts/fetch-tangled-lexicons.sh` to pull latest from tangled.org/tangled.org/core
20+
21+**Generated code from Lexicons**
22+- sqlx-compatible Row types for all 19 record types
23+- CRUD functions (upsert, delete, get, list) per record type
24+- SQL DDL migrations generated from Schema vertices/edges/constraints
25+- 24 XRPC Input/Params types generated from Lexicon query/procedure definitions
26+- 36 new Lexicon files for all XRPC query and procedure endpoints
27+- TypeScript interfaces now exported (`export interface`)
28+- Breaking change detection via `panproto_check::diff()` + `classify()` (`--check` mode)
29+
30+**Consumer dispatch**
31+- Generic dispatch table for simple records (upsert/delete with no side effects)
32+- Special-case arms only for records with business logic (counter updates, SSE events, state transitions)
33+- Centralized `at_uri` module replaces all inline AT-URI parsing
34+
35+**Replaced ~2,700 lines of hand-written code** with panproto-powered codegen and runtime transforms.
36+
