The SigV4 encoder kept '/' unescaped in object paths by swapping in a
"never matches" regex (/$^/) for query values, but that regex matches the
empty string, so every empty query value went out as "/": prefix= became
prefix=/ and ?policy became ?policy=/. The request then no longer matched
what was signed, and listing any bucket or reading its policy failed
against s3d. Bucket listing and creation carry no query, so they worked.
Verified end to end against s3d (list, folders, upload, download, public
policy, folder delete) and against the aws cli; two regression tests.
s3d is driven entirely by a CLI and a two-route admin API, which keeps
Sia storage out of reach for anyone who does not live in a terminal.
Pithos wraps it: install the pinned s3d release (checksum verified),
start/stop and logs, indexer login, users and access keys, a bucket and
object browser with share links and public-read policies, and the
upload pipeline stats.
One control server (core/) serves one UI (ui/), and three hosts run it:
a web console, an Electron desktop window and a Theseus add-on, so a
feature lands everywhere at once. The server binds loopback, rejects
foreign Host headers, and signs views in with a one-time secret that
becomes a SameSite=Strict cookie. s3d login reads the recovery phrase
with term.ReadPassword, so it is driven through a pty, with a console
window fallback where the pty module is not shipped.
