Release notes#

Minor release spanning 81 commits (v0.78.0..v0.79.0, 2026-07-30→2026-07-31). Headline: contextual keywords — tokenless parser surface (Batches A–G of the contextual-keywords campaign), plus the corpus split into radix/corpus with proba runners, the six-stage scripta/test ladder, cross-backend codegen fixes, and clippy pedantic debt clearing.

Major tracks#

Contextual keywords — tokenless parser surface (Batches A–G)#

The contextual-keywords campaign is complete: every batch-table word now has token_kind None. There is no global reserved keyword table — the lexer emits identifiers for all words and the parser recognizes keywords by spelling in grammar position, resolving the active reader-locale surface spelling. A word is only a keyword in the grammar slot where it is expected; everywhere else it is a free identifier.

Supporting work: contextual slot owners for Batch A keywords with tokenless rows enforced non-Global; tests prove migrated keywords work as contextual identifiers across use positions. Post-campaign fixes landed: exact declared spellings skip READER002 suggestions, and localized est <type> routes via reader_type_latin_keys.

Clean break: retired statement/token surfaces removed#

Per docs/factory/retired-statement-token-removal/goal.md, tempta, demum, emitte, the sed identifier-spelling check, the dead pro token, and the retired block-string spellings (❝...❞, """) no longer have keyword, token, grammar, locale, corpus, or diagnostic roles. Each spelling is an ordinary identifier now and fails generically; ❝ and """ fail as ordinary lex errors. Guillemets «...» remain the only block-string spelling. EBNF.md, localized EBNF, reader packs, corpus, and EBNF_MATRIX.md were cleaned in the same pass.

Corpus split & proba#

Single-file language exempla are now hosted in-tree under radix/corpus (the corpus-split goal moves package-shaped corpora to sibling examples/). A target-neutral proba inventory with a MIR stepper case runner lands tier-one proba on logic, binding, and control demos; radix test runs single-file MIR stepper proba. EBNF vocabulary and matrix are radix-only language law, and EBNF_MATRIX.md was regenerated for the radix/corpus join.

Six-stage scripta/test ladder#

./scripta/test is now a progressive six-stage ladder — gate → lint → proba → unit (nextest) → matrix → parity — ordered cheap-first so fast lanes gate before slow ones. New aliases: --check (stages 1–3), --release (stages 1–4 plus all e2e targets), --stage, and --e2e target selection (e2e is no longer a stage). CI is thinned to the scripta ladder: main push → --stage 1-4, tag push → --full.

Cross-backend codegen & semantic fixes#

• TypeScript: cross-file DefId resolution from sibling module imports; valor display and async entry for for-await.
• Go: blank-assign pure value expression statements.
• Rust: parenthesize numeric methods; Faber-null options.
• Semantic: lint warnings surface as non-fatal findings; diagnostics bag renamed from errors.
• Test temp data stays under the cargo-managed target tree.

Lint & polish#

Clippy pedantic debt cleared across the codegen crates (including radix-mir-llvm emit test fixtures); probe tests migrated from the radix façade into radix-mir-llvm/emit/; inline tests extracted across radix-mir-stepper, radix-lower-ts, radix-codegen-rust, radix-mir, and the radix façade. New tooling: scripta/release-stats.sh (per-tag tests vs LOC series).

Breaking / author-visible#

What is NOT included#

• No new language features beyond the contextual-keywords and clean-break surfaces above.
• No change to the MIR/GPU target posture; Metal factory campaigns remain paused.
• No changes to the faber product CLI surface (sibling repo release).

Version alignment#

Verification (pre-release)#

Recorded on the release candidate tree (2026-07-31):

Publish#

1. Bump all workspace crate versions 0.78.0 → 0.79.0 (not hygiene-ratchet).
2. cargo update so Cargo.lock matches manifests.
3. Verify locked release build + nextest.
4. Single commit with version bump + lockfile (+ this notes file if still dirty): release(radix): v0.79.0
5. Annotated tag: git tag -a v0.79.0 -m "Radix v0.79.0"
6. Push: git push origin main && git push origin v0.79.0
7. Monitor: gh run list -R faberlang/radix --limit 5
8. Confirm faberlang/releases publishes radix-v0.79.0 multi-arch archives.

Never tag a commit whose Cargo.lock is stale relative to the bumped manifests — CI uses cargo build --locked.
