Release notes#

Major bootstrap compiler push: the semantic analyzer and TypeScript codegen are now written in Faber and compile through the bootstrap toolchain. The language gains optional parameters (if/vel syntax) and alias bindings in pattern matching (as). The lege I/O form drops parens to match standard read/readline convention. Parser internals are cleaned up with extracted keyword predicates, fixed idiom bugs, and simplified casts.

Scale#

Major tracks#

Bootstrap compiler (self-hosting)#

• Adds the Phase 2 semantic analyzer for the bootstrap compiler (fons-fab/semantic/): 18 files, ~2,900 lines covering type resolution, scope chains, error reporting, and the Resolvitor pattern for mutual recursion (25a26fe81)
• Adds the TypeScript code generator written in Faber (fons-fab/codegen/ts/): 5 files, ~1,480 lines covering 24 expression types and 31 statement types (9474df2b1)
• Adds the codegen entry point and a minimal stdin→stdout CLI bootstrap compiler (8adfe3c61)
• Fixes 52 files across the bootstrap compiler: adds @ publicum exports, corrects SymbolumGenus enum member names (Semicolon→PunctumColon etc.), and fixes stdlib method names to match the list registry, reducing TypeScript errors from 358 to 299 (9b090eaf5)
• Refactors TS codegen from string concatenation to scriptum() builder (4a97381d3)
• Refactors codegen to use as alias binding in match blocks (df76c1982)
• Fixes scriptum() brace escaping in TS codegen (88632adcc)
• Removes unnecessary qua Expressia casts now that type inference handles match bindings (dea753769)
• Applies if optional parameter syntax in bootstrap compiler source (34c988410)
• Extracts statement-starting and genus-member keyword predicates from nucleus.fab into lexicon/verba.fab as a single source of truth, eliminating the maintenance hotspot identified by LLM reviewers (b042924df)
• Fixes specta/praevius parser idiom bugs in declara.fab, fluxus.fab, and imperium.fab; adds LLM Readability Goal to design philosophy (926c74e83)
• Adds lineam keyword to the fons-fab lexicon (9a923fed3)

Optional parameters (if/vel syntax)#

• Implements optional function parameters using if (if) to mark optional and vel (or) to provide defaults — syntax de si numerus depth vel 3 — with codegen for all 6 targets (TS, Py, Rust, C++, Zig, Fab) and semantic rules enforcing required-before-optional ordering (672e957d1)
• Documents the if/vel parameter modifier syntax in CLAUDE.md (5862d23f2)

Alias bindings in match pattern matching (as)#

• Adds the as keyword to bind a whole variant to a name instead of destructuring fields positionally with pro — codegen updated for all 6 targets (9031e9f56)
• Recommends as over pro for readability in CLAUDE.md (be26dc785)

lege stdin syntax change#

• Changes stdin reading from lege() to lege (read all) and adds lege lineam (read one line), following standard I/O convention of read vs readline; updates parser, AST, all codegen targets, and tests (2df48ca57)
• Regenerates grammar documentation for the new lege lineam syntax (fd88f7956)

Semantic analysis fixes#

• Fixes match pattern binding type inference: adds DiscretioType with variant field tracking so bindings like si Click pro x, y correctly infer field types instead of defaulting to unknown (475b8e9ce)
• Fixes discretio return type mismatch for finge...qua expressions: the resolveFingeExpression now looks up the actual discretio type from the symbol table instead of creating a mismatched userType() (98529af43)

Documentation and process#

• Updates AGENTS.md with workspace layout and process documentation (9488acba5)
• Merges CLAUDE.md into AGENTS.md (3219f9fd9), then adds grammar verification guidelines to AGENTS.md (2f4c49f35)
• Adds LLM cross-model validation finding to README (31cdedc89)
• Creates consilia/futura/si-intra.md — a planning document for an if-within-if guard clause pattern (20f75f287)
• Updates bootstrap-ts.md for parser completion (27 files, 6,259 lines) and progress tracking (6a5a6ec9e, 80756ce17, ac9d033ae)
• Adds test documentation files (5eeb8923d)

Other changes#

• Disables the format CLI command; the archived prettier plugin is removed (5574cb06e)
• Moves prettier source from fons/ to archivum/ (8e86d046f)
• Renames disabled prettier test (a35876011)
