fix(build): honour outDir and reject unsupported flags for --preset embedded - #3781
Conversation
…mbedded `handleBuildCommand` branched on `--preset embedded` before the config was loaded and passed on exactly one option, so `build.outDir` was ignored and every other flag the user typed was dropped in silence. `--dry-run` was the sharp one: a flag whose whole contract is "changes nothing" wrote a bundle to disk. The embedded preset emits a single esbuild bundle, so splitting, compression, prefetch, prerendering and the SSG include/exclude filters describe stages it does not have. Rather than pretend, the handler now rejects those flags with a usage error naming each one, and honours `-o/--output` and `build.outDir` through the same `resolveBuildOutputDir` the default path uses — which also brings its guard against an output directory containing the project. Validation runs immediately after argument parsing and before any bundler setup, so a rejected build touches nothing. It keys off `__explicit` on the raw argv: the parsed options carry schema defaults and cannot tell a typed flag from a defaulted one. Fixes #3585

Addresses the review finding on #3781. The note said the embedded preset "supports only -o/--output and build.outDir", but `--json`, `--verbose` and `--quiet` are not in the rejected set and pass the validator — the test suite asserts exactly that. Command help described working CLI behaviour as unsupported. Scoped the claim to build flags and noted globals are unaffected, rather than enumerating the global list, which would drift the next time one is added.
… preset Blocking review finding on #3781, and correct: routing the embedded path through `resolveBuildOutputDir` also picked up `assertOutputDirExcludesProject`, so `veryfront build --preset embedded -o .` went from working to a hard failure. Probed both sides — on origin/main the command succeeds and writes `./embedded/`; on the branch it throws. The guard's rationale does not hold on this path. Its doc comment says "The build clears its output directory before writing, so this would delete the project" — but that clearing is `adapter.fs.remove(outputDir, {recursive:true})` in src/build/production-build/build/build-setup.ts:41, which the embedded branch never reaches. `src/build/embedded/preset.ts` only does `fs.mkdir(embeddedDir, {recursive:true})` and never removes anything. For a preset whose entire purpose is being embedded into a host project, `-o .` writing `./embedded/` is a reasonable invocation, and nothing about it is destructive. `resolveBuildOutputDir` takes an opt-out named after the actual reason the guard exists — `clearsOutputDir` — rather than one named after the caller. The production path is unchanged and still guarded by default; only a caller that merely writes into the directory opts out. Three tests: the guard still rejects a project-containing output for a clearing caller, permits it for a writing caller, and `build.outDir` is still honoured when opted out — so the opt-out cannot quietly disable the resolution this PR added.

💡 Codex Review
veryfront-code/cli/commands/build/command.ts
Line 135 in e6d1a82
Redact absolute output paths in guard errors
When a user passes -o ., -o .., or an equivalent build.outDir, this guard interpolates resolvedOutput, an absolute project or workspace path, into CONFIG_INVALID; buildCommand then forwards that message to normal and JSON output, exposing the machine-specific filesystem layout in terminal or CI logs. Report the original relative value or a redacted placeholder instead.

fix(build): honour outDir and reject unsupported flags for --preset embedded
handleBuildCommandbranched on--preset embeddedbefore the config wasloaded and passed on exactly one option, so
build.outDirwas ignored andevery other flag the user typed was dropped in silence.
--dry-runwas thesharp one: a flag whose whole contract is "changes nothing" wrote a bundle
to disk.
The embedded preset emits a single esbuild bundle, so splitting, compression,
prefetch, prerendering and the SSG include/exclude filters describe stages it
does not have. Rather than pretend, the handler now rejects those flags with a
usage error naming each one, and honours
-o/--outputandbuild.outDirthrough the same
resolveBuildOutputDirthe default path uses — which alsobrings its guard against an output directory containing the project.
Validation runs immediately after argument parsing and before any bundler
setup, so a rejected build touches nothing. It keys off
__expliciton theraw argv: the parsed options carry schema defaults and cannot tell a typed
flag from a defaulted one.
Fixes #3585
Review notes
Built with red-green TDD. The red is carried by behaviour, not by a missing symbol: the
--dry-runtest assertsdist/embedded/manifest.jsondoes not exist, which fails onorigin/mainbecause the file is written — the bug stated verbatim.Decision taken (the issue asks for one decision covering all seven flags, and explicitly sanctions rejection): honour
-o/--outputandbuild.outDir; reject--dry-run,--split/--no-split,--compress/--no-compress,--prefetch,--ssg/--no-ssg,--include,--excludewith a usage error naming the flag.The subtle part is
__explicit. The parsed options carry schema defaults —split/compress/prefetchdefault totrueanddryRun/noSplit/noCompress/noSsgtofalse— so the parsed object cannot distinguish a typed flag from a defaulted one. Keying the validation off the parsed object instead of raw argv would reject every embedded build. The tests cover both polarities of each flag plus negative cases (bare embedded,-o out,--output out,--json,--verbose,--quiet) precisely to pin that.Not done, deliberately: honouring
--dry-runrather than rejecting it. That means threading a flag through five separate write sites insrc/build/embedded/preset.ts, which is a larger surface than this issue should carry. Worth a follow-up if wanted.Closes #3585
