A download that died on an HTTP 403 told the submitter "HTTP Error 403:
Forbidden" and told the log "error: exit status 1". The tool's stderr went
into status_msg and nowhere else, so the one person who could act on it saw
nothing. Exactly backwards.
Failures now go through a.fail: the submitter gets a sentence and an eight
character code, the log gets that code, the stage, the submission, the
source URL and the stderr tail. Quote the code, grep the log, find the line.
Every record carries file:line now, and LOG_LEVEL sets the threshold —
failures are logged at error, so no level hides them.
Thirty-seven entries in the root, most of them .go files. The assets had to
come along: //go:embed cannot reach outside its own directory, so
templates/, static/ and migrations/ live beside the code that embeds them,
and testdata/ beside the test that reads it. storage/ stays put — runtime
data, not source.
go build now needs -o. Without it the output would be named after the
package directory and collide with src/ itself.
