# Engine builds
|
|
|
|
Version 0.1.0 ships no WebAssembly engine.
|
|
|
|
`npm run engines:build` verifies that this release has no external pack to
|
|
build. After the production build, `npm run engines:verify` rejects any
|
|
undeclared engine asset and confirms the packaged ECMAScript-only notice.
|
|
Neither command accesses the network.

## PCRE2 feasibility record
|
|
|
|
The next flavour was spiked outside the application repository against official
|
|
PCRE2 10.47:
|
|
|
|
- signed tag object `cd007b4466798f66d479d1442a407099e7c40050`;
|
|
- peeled commit `f454e231fe5006dd7ff8f4693fd2b8eb94333429`;
|
|
- licence `BSD-3-Clause WITH PCRE2-exception`;
|
|
- Emscripten 6.0.4;
|
|
- 8-bit library, Unicode enabled, JIT disabled.
|
|
|
|
Node and Chromium tests demonstrated version/config reporting, Unicode,
|
|
named groups, global substitution, automatic and explicit callouts, and
|
|
match/depth/heap errors. This was a technical spike only. No spike source,
|
|
binary or PCRE2 source is included in v0.1.0.
|
|
|
|
Production PCRE2 support remains gated on a reviewed bridge, copied DTOs,
|
|
allocation cleanup, exact source build, UTF-8/UTF-16 mapping, trace/output caps,
|
|
worker recovery, deterministic assets, licences and browser conformance.
