0.1.0 (2026-06-12)

First release shipping the CEM-ML / CEM-QL engine and the <cem-element> substrate. (Curated from docs/release-readiness-0.1.0.md; the conventional-commits auto-changelog does not represent this release — see §8.)

🚀 Features

CEM-ML engine (cem_ml) — layered tokenizer → event normalizer → schema machine → AST: @doc version negotiation, namespace rebinding, schema scoping, Layer-5 handoff, unknown-namespace disposition (AC-P-6.7), and XSLT region dispatch (AC-P-6.8).
CEM-QL engine (cem_ql) — compile-once / render-many WASM boundary, /datadom selection, cem:for-each / cem:if / cem:choose, and an XPath-parity stdlib (str:*, seq:*, num:*).
<cem-element> substrate (@epa-wg/cem-elements) — runtime slices A–E, C2 WASM lowering, serializable projection boundary, edge render-state, and SSR hydration with BR-VC-9 disposition.
@epa-wg/cem-components — base primitives authored entirely against <cem-element>.
Legacy HTML+XSLT backward-compat — legacy <custom-element> HTML+XSLT templates are transpiled to canonical CEM-ML by the single CEM-owned engine (cem_ml::legacy_custom_element, shared by browser / CLI / SSR / tests) and rendered on the cem_ql engine — no browser XSLT processor — so legacy demos render identically to their migrated CEM-ML twins.
cem-theme — all 10 CSS generators converted off the browser XSLT 1.0 runtime to type="cem-ml; version=0.0" (Option B); DTCG / Figma / native token-platform export pipeline.
Governance — fitness functions FF-1..FF-8 all CI-blocking and active, the FF-gate map, and governed-contract SemVer axes.

💥 Breaking changes

The browser-native XSLT 1.0 XSLTProcessor engine is retired from @epa-wg/custom-element; legacy HTML+XSLT runs via DOM→CEM-ML conversion on the substrate (Tier 1/2; standalone XSLT stylesheets are a deferred Tier-3 handoff).
cem-theme CSS generators no longer use the browser XSLT runtime — the generated dist/lib/css/*.css is unchanged, so CSS consumers are unaffected; only forked/embedded generator HTML must migrate.
Versioned governed contracts apply a run-mode disposition on ingest (BR-VC-9): a data/security payload whose schema MINOR is ahead of the consuming build is rejected in application runs.
Prefer package export subpaths over deep dist/ imports.

See docs/release-readiness-0.1.0.md for the full breaking-change list, bridge-window support matrix, and rollback plan.
