Re-model the web file host as a file server (not a website host):
- Drop the misnamed /site area. A member's public files are now their
/me/public subfolder (unix ~/public), served anonymously at
~<name>/public. The rest of /me stays private; only ~name/public is
ever exposed. Bare /~name redirects to /~name/public/.
- The root / is now a directory of ALL members, each linked to their BBS
site (https://<bbs-host>/~name via WebConfig.SiteBase) AND their public
files here (~name/public). No longer hides empty members.
- Sites/homepages stay on the BBS — files.<host> only links to them.
- Usage gauge is just /me again (which includes /me/public).
setup.sh + docs updated; tests cover ~name/public browse/download, the
bare-~name redirect, empty-member empty-listing, /public-only exposure,
and traversal confinement.

Add a third storage area, /site — each member's own public root, served
unauthenticated on the web at ~<name> alongside the shared /public.
Web file host (files.<host>) is no longer a login wall:
- GET / -> directory of members' ~user sites (+ sign-in link)
- GET /~<name>/... -> anon read-only browse + clean file URLs of /site
- GET /public/... -> anon read-only browse + clean file URLs of shared
area (fixes bare /public requiring login: the old
Caddy `handle_path /public/*` never matched /public)
Login is now optional and gates only private /me + writes. The anon
surface has no route into anyone's /me and safeJoin rejects traversal.
Usage gauge now sums the member-owned areas (/me + /site) instead of
/me alone; shared /public stays operator-managed and unmetered.
Caddy: route all of files.<host> to the Go manager. Docs + tests updated
(anon download/browse, traversal confinement, /site metering).

* feat(files): provision-user CLI + anonymous public HTTP serving
Lets external services (the TronBrowser extension store) host files on
files.profullstack.com without the interactive `ssh join@` onboarding.
- `agentbbs provision-user --name <h> --pubkey "<ssh key>"`: registers a member
from an SSH *public* key (account = handle + key fingerprint). Reuses
SanitizeUsername (same rules as join@) + EnsureUser; Files/SFTP access is free
for members, so the account can immediately
`scp … files@host:/public/extensions/<slug>/`. JSON output; refuses on key/
handle collision. New auth.FingerprintAuthorizedKey() parses an
authorized_keys line to the same SHA256 fp as a live session key (tested).
- setup.sh: the files.<host> Caddy site now serves the shared /public area as
unauthenticated, read-only static files (handle_path /public/*), so .crx/.zip
download links work for anyone — mapping 1:1 to the SFTP path. Non-/public
paths still hit the auth'd web file manager.
- docs/files.md updated.
Note: not compiled here — repo go.mod requires go 1.26 and this sandbox has
1.22.2; changes pass gofmt parse/format checks. Reuses existing store/auth APIs.

* fix(vet): redundant newline in wish.Println premium-flow messages
`go test ./...` / `go vet ./...` fail on `wish.Println(… "…\n")` — Println
already appends a newline. Pre-existing on main (its CI is red for the same two
lines); surfaced here. Switched both to `wish.Print` with an explicit trailing
"\n\n" so output bytes are unchanged and vet is satisfied.

Implements M4 (Files). A fully virtual Go SFTP server (pkg/sftp + crypto/ssh,
no OS users) wired as an "sftp" subsystem on the existing :22 wish listener, so
members reach their files with their login key:
sftp files@bbs.profullstack.com # scp/rsync ride the same endpoint
Identity is the SSH key (the username is conventional/ignored). Two areas per
session: a private, quota-limited /me workspace and a single shared public file
area /public (old-school BBS file area; world-read, members-only write by
default, operator-moderated). This reverses the old NG1 "no sharing" boundary in
favour of one sanctioned, inspectable sharing surface (PRD §9.3 amended).
internal/files:
- backend.go service, layout, quota/usage, live-session registry, operator API
- fs.go per-session virtual FS; resolve() is the single security
chokepoint (area confinement + symlink-escape guard) + pkg/sftp
request handlers
- server.go subsystem handler: key auth -> member session -> request server,
with byte metering and force-disconnect
- tui.go in-BBS member browser (hub plugin "Files")
- admin.go operator management TUI: sessions, workspaces/quotas, public area
Operator console: ssh sftp@<host> (allowlist-gated; sftpadmin@/filesadmin@
aliases) — list/disconnect sessions, set per-user quotas, revoke SFTP access,
toggle public write, moderate the public area.
store: files_access (per-user quota override + revoked) and files_settings
(public-write mode) tables + methods. main.go wiring guarded by AGENTBBS_FILES
(+ AGENTBBS_FILES_QUOTA_MB, default 1 GiB). Route names reserved.
Tests (incl -race): path traversal/confinement, symlink-escape rejection,
public-write ACL, quota enforcement, usage accounting, and an end-to-end run
against a real SFTP client. Docs: docs/files.md; PRD §5.3/§5.3.1/§9.3 + README
updated.
