Scaffolds a **directory** bundle — the only shape that can own local files, so the
other kind would hand an author a page their pictures cannot live beside. What it
writes is a draft: title, today's date, `draft: true`. A tool that publishes the
moment it runs publishes by accident, and drafts are honoured now.
This is the first thing that writes into somebody's content directory, so it goes
through os.Root like every read does (ADR-0031), and it never overwrites: an
existing bundle is an error.
Two bugs found by running it rather than by testing it:
A key of `../escape` did not fail. It never left the site root — path.Join collapses
`..` first — but it wrote a real directory *inside* the root and outside content/,
which is not an escape and not a bundle either. Refused outright now, the same guard
the include path needed for the same reason. The test asserts what should be true —
content/ is the only thing this creates — because the weaker assertion I wrote first
would have passed.
`khosra new posts/x -site dir` silently ignored -site, because Go's flag package
stops at the first non-flag argument, and then failed complaining there was no site
root. Parsed in rounds now, so either order works.
main() crossed the function-length warning as a result, so it became a dispatch
table with runServe beside it — the warning was right about the code.
The server never fails on a bad bundle — it works around it and logs, which is easy
to miss (ADR-0029). This is the command that looks on purpose, and it exits non-zero
on anything that makes the site wrong rather than merely untidy.
Fatal: content the engine had to drop (unparseable frontmatter, a key two files
claim, an ignored slug or alias) and links that will 404 for a reader. Warnings:
no title, a figure with no alt text, a series where some members declare order and
others do not — that last one because unordered members sort last, so adding order
to one chapter silently moves every chapter that lacks it.
Two things this needed rather than invented. `Scan` and `Site` now *return* what they
worked around instead of only logging it: `ScanReport` and `Site.Problems`, with
`Scan` staying the logging wrapper so nothing else changed. And required-fields-per-type
is deliberately absent — `title` is the only field the engine requires today, so
checking more would mean inventing the type declaration that is still parked. Its
trigger stays where it was.
The link checker asks the same questions the resolver asks — bundle, alias, section
listing, file inside a bundle — because a checker that guesses differently from the
server is worse than no checker. Engine-owned paths are skipped: they are generated,
not authored.
It lives in internal/ext/check, so cmd/ stays wiring and the feature stays deletable.
Verified against the evidence site: clean before, and five findings across five fault
classes after I introduced them on purpose.
So the thing can be built and run without reading the harness. Eight targets,
each one go command or verify.sh; make help lists them. README gains the four
lines someone actually needs, and says a site root is a directory the binary is
pointed at rather than something in this repo.
make is recorded in toolchain.md as a convenience: the gate never invokes it, so
a machine without make loses nothing but typing.
