Release notes#

Substantial standard library expansion — new HTTP, serialization, database, and string modules — alongside collection-type morphology validation, receiver ownership inference, and per-target helper library support.

Scale#

Major tracks#

Standard library: new modules#

• caelum — HTTP client (pete, mitte, pone, dele, muta, roga) and server (exspecta, Servitor) with @ futura async annotation (074d16694)
• arca — Database adapter protocol with Connexio/Transactio pacta, TypeScript PostgreSQL and SQLite drivers (6fc5f8364)
• forma — Serialization/deserialization: solve(valor, "json") → bytes, pange(bytes, "json") → T; supports JSON, YAML, TOML, CSV (4c343d66e)
• textus — String methods (longitudo, sectio, etc.) and type propagation for string codegen (4fbf01ab8)
• numerus / fractus — Math operations (absolutum, signum, rotunda, etc.) and float literal typing fix (f02c386d7)

HTTP API consolidation#

• Rename responsum/rogatum → Replicatio/Rogatio to avoid collision with the language-level Responsum async protocol (4c084a545)
• Simplify server API: exspecta(handler, port) replaces creaServitorem()+exspecta() (1f7c05467)
• Remove convenience response builders (replica, replicaJSON, replicaErrorem); keep only replicatio(status, capita, corpus) for full control (459da8246)
• Remove peteCum/mitteCum convenience methods; use roga(modus, url, capita, corpus) instead (a04b0d07a)

Collection types: morphology validation and codegen#

• Add @ radix annotations to collection methods (lista, tabula, copia, solum, aleator) for morphology/behavior alignment (e93755f75)
• Rename methods to match perfectum semantics: selige→selecta, omit→omissa, confla→conflata, misce→miscita (e93755f75)
• Add receiver ownership inference from verb morphology: imperative/future indicative → mut (mutable), perfectum → ref (immutable) (521676930)
• Add Latin morphology validation (morphology.ts) wired into all 5 codegen targets (TypeScript, Python, Rust, C++, Zig); invalid forms emit warning comments (e2944c58b)
• Add collection helper libraries for Rust and C++ targets to replace complex inline lambdas in codegen templates (6520dede3)
• Fix parameter substitution bugs where single-param templates with multiple § references relied on auto-increment instead of explicit §0 (2e3387827)
• Add missing parameter and return types to mathesis (21), solum (27), and tempus (5) stdlib functions (f8003c61b)
• Update test coverage: 27 new lista cases, 7 new tabula cases (b0eb879f4)

Support libraries per target#

• TypeScript: full HTTP client/server implementation using fetch API and Node.js http module (d8d673e9c)
• Rust and Zig: compile-time stubs (unimplemented!() / @compileError) with clear messages (ec18ed93a)
• Python: runtime stub raising NotImplementedError (98b266bee)
• C++: runtime stub throwing std::runtime_error (6df23fc65)

Semantic analysis and type propagation#

• Cross-module type propagation for codegen: fix dicserne pattern alias for variant field access, fix EgoExpression to resolve enclosing genus, restrict mathesis constant lookup to zero-arg functions (4fbf01ab8)
• Add string as a primitive type in the codegen translation layer with property mapping (longitudo → length) (4fbf01ab8)
• Infer float literals as float type in semantic analysis (f02c386d7)

Other changes#

• Regenerate norma registry from updated stdlib specs (3964f8a54, 0b7b5d09e)
• Add stats generation script (scripta/stats.ts) for README automation (7e30c3b2b)
• Add project statistics table to README (d0a6d26e9)
• Restructure AGENTS.md with elevated CRITICAL RULES section (e48be0f00)
• Update docs for renamed stdlib methods across 9 documentation files (842329415)
• Add @ proprietas design proposal for property-style access (dd07b8b0b)
• Add test-fixer and typescript-fixer agent configurations (b0eb879f4, b7dcc2b24)
• Add brief test data for agent evaluation (4a106b190)
• Fix strict null checks across test and script files (cb4a78ec7)
• Style cleanup in faber compiler tokenizer and assignment expression (0aba080ca)
