The zerolag bundle exports only `XtermZerolagInput`, but app.js constructs
`new LocalEchoOverlay(terminal)` directly. scripts/build.mjs appends global
aliases after esbuild (build.mjs:53-66); the first version of this script
omitted that step.
Without them initTerminal() throws `LocalEchoOverlay is not defined` at the
line that builds the overlay — and because that is midway through the function,
EVERY later step silently never runs, including the mobile touch handlers on
#terminalContainer. The page still had a terminal, so the failure looked like a
tap-routing bug rather than a boot error.
Verified: boot errors none, and all four terminalContainer touch listeners
(touchstart/touchmove/touchend/touchcancel) now register.
The mobile suite drives a real browser against a WebServer started from
TypeScript source, so fastify-static serves join(__dirname, 'public') =
src/web/public — not dist/web/public, where `npm run build` puts the vendor
bundles. Every /vendor/xterm* request 404s, so `Terminal` is never defined,
initTerminal() never runs, and any test touching app.terminal dies with
"Cannot read properties of null".
Measured in one worktree, toggling only the vendor files:
before: 404s=5 Terminal=undefined app.terminal=null 8 failed | 26 passed
after: 404s=0 Terminal=function app.terminal=live 6 failed | 28 passed
The 6 remaining failures are genuine pre-existing bugs (stale layout and
accessory-bar expectations, a CJK timeout) and are left alone here.
This went unnoticed because config/vitest.ci.config.ts excludes test/mobile/**,
so CI never ran the suite. `npm run test:mobile` now runs it, with a pretest
hook that builds the bundles.
The asset list was derived from the actual 404s rather than from build.mjs —
which is how xterm-addon-unicode11 and xterm-zerolag-input got included; reading
the build file alone would have missed both. Outputs go to the gitignored
src/web/public/vendor/, so they stay build artifacts. The script is idempotent
(skips outputs newer than their source) and does not touch the normal build.
Full CI suite unchanged: 4368 passed.
