chore: stop tracking the docs/changes ledger
docs/changes held 26 per-feature change notes and their index, written while each feature was built. They were working records, not documentation: they cite internal milestone numbers and plan steps, several describe designs that changed before they shipped (the nano note's config schema and a proxy plugin that was never built), and nothing in the code, the build or the other docs refers to them. New notes stopped being added a while ago; the commit messages carry that record now. The directory leaves the tree in this commit. Its contents stay reachable in history, and the files were kept outside the repository before removal. No code, build or test changes. |

fix(bootstrap): keep the nano build toolchain under /opt/felis
The source build of the nano binary installed Go at /usr/local/go and replaced whatever version was already there. On a host that also builds other things, the operator's own toolchain was removed and swapped for Felis's pinned version without a word. GOROOT_DIR is now /opt/felis/go, next to the source, the Velocity install and the JRE Felis already keeps under /opt/felis, and install_go_toolchain creates the parent before unpacking. A host where an earlier run put Go at /usr/local/go downloads it once more on the next re-run and keeps the old tree untouched; removing it is the operator's call. The harness now requires the toolchain directory to be under /opt/felis. |

fix(bootstrap): open the nano port to the proxy alone
For a non-loopback bind, configure_nano_firewall opened the nano port in firewalld to every source, while the summary told the operator to restrict it to the proxy. hasJoined takes no token, so on a public host that port is an auth relay anyone can point a proxy at, spending this host's Mojang egress until Mojang rate-limits it and the operator's own players stop getting in. A new FELIS_NANO_PROXY_CIDR names the proxy. With it, firewalld gets one rich rule that admits the port from that source only, ipv4 or ipv6 by the address given. Without it, no port is opened and the summary prints the rule to add. A re-run closes the port an earlier installer opened to every source. A rule for a previous FELIS_NANO_PROXY_CIDR is not tracked and stays until removed by hand. Hosts without firewalld are handled as before. The value goes into the rule text, so it is checked up front for an address with one prefix length and nothing else. firewalld's own parser accepts both rule forms and refuses an ipv6 address under the ipv4 family. The harness covers the rule for each family, the closed-by-default case, the re-run cleanup, the loopback case and the CIDR check. |

fix(config): refuse plaintext auth-source urls to public hosts
An auth_source url could be http:// to any host. Anyone on the path to a public root, or anyone who can spoof its DNS name, can then answer hasJoined with a 200 and log in as any player of that source, including a third-party account linked to staff. The player's IP also travels in cleartext. Mojang logins are unaffected, since that source is built in over https. Config load now refuses http:// unless the host is localhost or a loopback or private IP address (127.0.0.0/8, ::1, 10/8, 172.16/12, 192.168/16, fc00::/7), so a root on the same host or the LAN still works without TLS. The decision is made on the literal host because nothing is resolved at load time, so a LAN root named by hostname needs its IP address or https. The error says what to change. The new test covers public names and addresses, link-local, 0.0.0.0 and the first address past 172.16/12 (all refused over http, all accepted over https), and the loopback and private forms that stay allowed. It fails on the old check. |

fix(nano): stop trusting an expired free name while mojang is failing
When the premium-name lookup failed, isPremiumName fell back to any cached answer, however old. An expired "free" is exactly the answer that may have stopped being true: someone can buy the name after it was last seen free. For as long as api.mojang.com kept failing (429, 5xx, a timeout), a third-party player holding that name kept it on every reconnect, and the Velocity registry, keyed on the name, turned its new owner away as already connected. A hostile source could drive the host into Mojang's rate limit on purpose to hold names that way. A failed lookup now always counts as taken, so the player is renamed with the source's prefix. An expired "taken" already gave that answer, so only the stale "free" case changes. The cost is cosmetic: during an outage an ordinary third-party player may get a prefix they do not need, and their data follows the UUID, not the name. A new test gives the cache a free entry past its TTL and has Mojang answer 429. It fails on the old fallback. The two comments that described the fallback now describe the fail-closed rule. |

fix(bootstrap): refuse an unbracketed ipv6 nano listen address
validate_listen checked only the port, so FELIS_NANO_LISTEN=::1:8081
passed. Go refuses that form ("too many colons in address") and needs
[::1]:8081, so the unit crash-looped on every start. A host part that
contains a colon must now be in brackets.
With that, the bare ::1 pattern in nano_listen_is_loopback can no
longer match an address that gets this far, so it goes. [::1] stays.
The harness adds ::1:8081 to the refused addresses, and [::]:8081 and
:8081, both of which Go binds, to the accepted ones.

test(bootstrap): pin the nano listen default to loopback
nano_listen_is_loopback decides whether configure_nano_firewall opens the port, and hasJoined takes no token. A default that does not classify as loopback would make every fresh nano host a public auth relay. The harness now runs the classifier on four loopback binds and three routable ones, and feeds it the default resolve_nano_listen applies on a first install, with no operator value and no existing unit. Setting that default to 0.0.0.0:8081 or :8081, or counting 0.0.0.0 as loopback, now fails the harness. Test only. |

fix(bootstrap): open up a nano-only config dir an older run left 0750
write_nano_config creates a missing /etc/felis as 0755, but it left an existing one alone. On a nano-only host an older installer made that directory with a bare mkdir -p, so under a root umask of 027 it is 0750. The DynamicUser unit cannot search it, so felis-nano cannot read its config, and a re-run stops at the service check instead of repairing the directory. An existing directory is now set to 0755 unless it holds the full install's secrets.env or bootstrap.done. The full install locks the directory to 0700 and writes secrets.env right after, so its directory keeps that mode, and install_nano_service still reports the lockout rather than this widening it. The mode cases run only where chmod works; on a filesystem that ignores it the harness skips them. |

docs(bootstrap): say auth_source tags are permanent and order is trust
Both config templates the installer writes, the nano felis.toml and the comment above [[auth_source]] in the generated felis tomls, now state two things an operator editing the list needs to know. A tag is hashed verbatim into every player UUID of its source, with no case folding, so renaming it gives all of those players new UUIDs and orphans their data, links and bans. The list is scanned in order and the first source that validates wins, so order is trust, and a compromised root has to be removed, not moved down. Comment text only. |

fix(bootstrap): fail a tokenless private clone instead of prompting
A source build against a private repository with no FELIS_GITHUB_TOKEN, or a wrong one, made git ask for a username on /dev/tty, and a piped install sat there waiting. git_auth now runs git with GIT_TERMINAL_PROMPT=0 on both arms, so git fails at once with "terminal prompts disabled". Both fetch_source failures name FELIS_GITHUB_TOKEN in their message: the fresh clone, and the fetch into an existing checkout, which had no message of its own before. |

fix(bootstrap): detect a missing terminal by opening /dev/tty
prompt_install_mode guarded its prompt with `[ ! -r /dev/tty ]`, which never fires on Linux: /dev/tty is mode 0666 whether or not the process has a controlling terminal, and only opening it fails. Without a terminal the menu was printed, the read failed with "No such device or address", and the default was taken by accident rather than by the documented path. The guard now opens /dev/tty in a subshell and takes the "no terminal for a prompt" path when that fails. |

docs(bootstrap): pass tunables on the sudo line, not by export
The header said to export tunables before running, but its own `curl ... | sudo bash` entrypoint resets the environment, so an exported FELIS_INSTALL_MODE or FELIS_NANO_LISTEN never reached the installer. The header now shows the two forms that do arrive: the variable named on the sudo line, or export followed by sudo -E. The nano summary's hint for a proxy on another machine now prints a sudo line that can be pasted as is, instead of "re-run with FELIS_NANO_LISTEN=...". Comment and log text only. |

fix(bootstrap): verify the go toolchain tarball against a pinned digest
install_go_toolchain downloaded the tarball to a fixed /tmp name and unpacked it into /usr/local as root, with no digest check. Another local user could plant that file first, and nothing would notice a tampered download. The tarball is now staged in a mktemp -d directory that the exit cleanup removes, and its sha256 must match before the old toolchain is touched, so a refusal leaves the host as it was. The default 1.26.4 carries pinned amd64 and arm64 digests next to its version; they are the ones https://go.dev/dl/?mode=json&include=all publishes. Any other FELIS_GO_VERSION has to bring its own FELIS_GO_SHA256, documented in the header, because no pin can cover a version chosen at run time. Where and which version gets installed is unchanged. |

fix(bootstrap): print the address nano binds in the install summary
summary_nano printed the node's primary IP for every non-loopback bind and 127.0.0.1 for every loopback one. A bind to a second private address, or to [::1], handed the operator a hasJoined URL that nothing listens on. The host is now the part of FELIS_NANO_LISTEN before the last ':'. The node's IP is used only for a wildcard bind (empty, 0.0.0.0 or [::]), which names no address a proxy could dial. The loopback and public-bind notes are unchanged. |

fix(bootstrap): refuse a nano listen address without a usable port
FELIS_NANO_LISTEN was never checked. A bare 8081 opened port 8081 in the firewall while nano bound nothing, a bare 127.0.0.1 printed http://127.0.0.1:127.0.0.1/... in the summary, and the unit crash-looped either way. validate_settings now requires a ':' and a decimal port of 1-65535 after the last one. It runs after resolve_nano_listen, so an address read back from an existing unit is checked too, and the default always passes. [::1]:8081 and 0.0.0.0:8081 are accepted. |

fix(bootstrap): install only the full control plane under felis setup
prompt_install_mode also runs inside felis setup. Setup then goes on to the Owner and edge setup, which need the control plane, so choosing nano there always ended in a setup error. Under felis setup the mode is now full before any prompt or default is considered, and an explicit FELIS_INSTALL_MODE=nano stops with a message pointing at deploy/bootstrap.sh. That leaves the felis setup branch of acquire_nano_binary unreachable, so it goes. install_embedded_binary stays, since the full install still uses it. |

fix(bootstrap): keep a nano host's listen address and mode on re-run
Re-running the installer is how a nano host updates. That re-run reset FELIS_NANO_LISTEN to 127.0.0.1:8081, so a proxy on another machine lost its endpoint and every login through it failed. It also offered the full control plane as the default, which on a nano host means k3s and Postgres nobody asked for. The listen address is now settled by resolve_nano_listen, the first step of main, so the later checks see the result. The operator's value wins, then the -listen argument of the installed felis-nano unit, then loopback. The install mode defaults to nano, at the prompt and without a terminal, when the felis-nano unit exists and the full install's bootstrap.done marker does not. Only the full install writes that marker. The harness reads back the unit it wrote earlier, and checks the mode default on a nano-only host, a host with the full install, and a fresh host. |

fix(bootstrap): carry auth_source tables with spaced or quoted headers
A re-run copies the operator's [[auth_source]] tables from the existing felis toml into the new one. The awk program that finds them matched only the literal header [[auth_source]], so a table written as [[ auth_source ]], [["auth_source"]] or [['auth_source']], all valid TOML, was taken for some other section and dropped from the config. Each section header now decides afresh whether it opens an auth_source table, through one regex that allows inner whitespace and a single- or double-quoted key. The single quote is spelled \047, which gawk and mawk both honour inside a bracket expression. The harness carries each spelling and checks that the table still stops at the next section. |

fix: keep internal section numbers out of runtime messages
Four messages that reach an operator or an API client cited sections of a specification nobody outside the project can read: - the unimplemented archive store error from config load - the running-server cap refusal, from both the user wake and the internal wake - the missing memory ceiling guard, in the API and in felis apply The references are gone and the wording is otherwise unchanged. Each message still says what went wrong and, where there is one, what to do about it. The test for the archive store message checks for the tarLocal remediation, which is still there. |

docs(openapi): list every answer hasjoined gives
The hasJoined contract listed only 200 and 204 and named authlib as the caller. The handler now answers four more ways, and a proxy operator reading the contract could not tell a refused login from a down source. - 204 also covers a missing or oversized parameter (no source is asked), a third-party name that is not a legal Minecraft username, and an identity id that does not parse. - 400 for a request that declares a body. There is no response body, and the connection is closed. - 500 when the bar-list lookup fails, with the usual error body. - 503 when no source validated and at least one failed, since that source's player may be the one logging in. The three query parameters now carry the 64-byte cap. The profile name says a third-party player holding a registered Mojang name gets it back prefixed and cut to 16 characters. The description names Velocity, drops the "thin login hook" that does not exist, and says that a non-200, non-204 answer makes Velocity report the auth servers as down. |

docs(nano): describe the hasjoined path as it works
The comments around hasJoined still described an authlib client that is not in the path. Velocity reads -Dmojang.sessionserver and sends the request itself, and it turns a 204 into its online-mode-only kick, not authlib's "failed to verify username". The route comment in api.go also offered "a thin login hook" as an alternative that does not exist. Other comments had drifted from the code: - The [[auth_source]] doc said an empty list ships the multiplexer off. Mojang is always prepended, so an empty list means Mojang is the only source. - The premium-name cache said Mojang does not recycle names. A name frees up when its owner renames away. The day-long "taken" TTL still holds, because a stale "taken" costs a third-party player only a prefix. - The cache bound claimed entries come only from players who authenticated somewhere. Any third-party source that validates a login adds one, so a hostile source can force the map to clear. That costs repeat lookups, or a fail-closed prefix while Mojang is unreachable, never an identity. The rewrite rationale now states what it costs a backend operator. A chat-session key that a third-party source signed over its native UUID cannot verify against the canonical UUID, so chat from those players can only be accepted unsigned. In the tests, comments that repeated their subtest names are gone. |

test(nano): cover the nano delivery path and its loopback default
felis nano serves the same hasJoined handler as felis api, but behind nanoStubRepo, which implements only the bar-list lookup and embeds a nil Repo for everything else. Only the full-api path was tested, against a complete fake store, so a second store call added to handleHasJoined would pass CI and panic on every nano login. The loopback default of -listen, the one thing keeping nano from being an open auth relay, was not pinned either. The default moves into a nanoDefaultListen constant, and two tests cover the path. One serves a login through api.HasJoinedHandler with nanoStubRepo and a fake identity source and expects the profile back. The other requires the default to parse as a loopback IP. Taking the bar-list method off the stub makes the first panic on the nil Repo; defaulting to 0.0.0.0:8081 or :8081 fails the second. |

test(config): make the identity-key test fail when the key is accepted
TestLoadRejectsAuthSourceIdentityKey is the guard against a config line identity = true making a third-party source's UUIDs trusted as-is. Its fixture had no prefix, so Load failed on the prefix rule and the test passed on that error. With the unknown-key check in decodeConfig disabled, the test still passed. The fixture now carries a valid prefix, the error must mention unknown keys and identity, and LoadNano is checked alongside Load. With the unknown-key check disabled, both loaders now fail the test; the old version of the test passes against the same change. |

test(nano): cover the bar-list error, bad identity id and ip relay
Three paths in handleHasJoined had no test that fails when they break: - A bar-list lookup error answers 500. Logging it and carrying on would admit a reclaimed squatter during a database outage. - An identity (Mojang) id that does not parse answers 204. Ignoring the parse error would emit the nil UUID for every such login, so they all share one player's data. - The ip parameter is relayed to each source. Dropping it turns off the sources' check that the session is used from the player's own address. One subtest each. Mutants that ignore the bar-list error, ignore the id parse error, or stop appending ip each fail their subtest. |

test(nano): cover the premium-name cache rules
isPremiumName decides on every third-party login whether the player keeps their name, and none of its rules had a test that fails when the rule breaks: treating a 429 or 5xx from api.mojang.com as "free", swapping the free and taken TTLs, flipping the freshness comparison, answering "free" from an expired taken entry during an outage, or dropping the clear-at-4096 bound. Each of those leaves a squatter holding a name its owner has bought, or grows the cache without limit, with CI green. TestPremiumNameCache drives isPremiumName against a stub that answers with a fixed status and counts lookups, and seeds cache entries at chosen ages. Five mutants of handlers_hasjoined.go, one per rule above, each fail at least one subtest. It does not test an expired "free" entry during an outage; what that case should return is still open. |

test(nano): pin the auth namespace and one rewritten uuid as literals
The rewrite test computed its expected UUID from felisAuthNS itself, so a change to the namespace seed moved both sides together and still passed. Such a change gives every third-party player a new UUID on next login, orphaning their playerdata and account links and letting any squatter barred by the old UUID back in. The test now also compares felisAuthNS and the rewrite of littleskin:<Notch's id> against fixed strings, 07228eae-77f6-500e- 9dc0-436afbc87c27 and b63bcc1c611432eeb7b3af3a15012e48.

test(api): keep the package's tests off the live mojang profile api
mojangProfileAPI defaults to https://api.mojang.com, and only the tests that call stubMojangNames or setProfileAPI swap it out. A new test that reaches a third-party login without doing so would query the real service: its result then depends on network access and on whether someone owns the name that day, and the shared premium cache can carry that answer into later tests. A TestMain now points the lookup at an address nothing listens on before any test runs, so a forgotten stub always takes the same fail-closed path. Tests that stub it restore this address, not the live one, when they finish. |

fix(nano): say that [server] listen is ignored instead of defaulting it
LoadNano filled in [server] listen = "0.0.0.0:8080" when it was unset, and a test pinned that value, but felis nano never reads it: it binds the -listen flag, which the installer sets from FELIS_NANO_LISTEN. An operator moving nano off loopback by writing [server] listen in its config got connection refused from the proxy and no hint that the key did nothing. LoadNano no longer sets the default, and nano prints a line naming the ignored value and the address it actually binds whenever the key is set. It is a warning rather than a load error so a full felis.toml copied onto a nano host keeps starting. The assertion that pinned the unused default is removed along with it. The new test runs cmdNano against a config that sets [server] listen and one that does not, with an unbindable -listen so it returns after loading. The first must warn and the second must not; with the old default restored, the second prints a warning about 0.0.0.0:8080. |

fix(nano): drain in-flight logins on shutdown
The installer and the config template tell the operator to run systemctl restart felis-nano after editing the source list. nano had no signal handling, so SIGTERM killed it mid-request: a login waiting on an upstream had its connection reset, and Velocity disconnected that player with "authentication servers are down". felis api already drains on shutdown; nano did not. nano now listens itself, serves until SIGINT or SIGTERM, then shuts the server down gracefully with a 30-second limit. That outlasts the source scan of any realistic list, at five seconds per source, and stays well inside systemd's default 90-second stop timeout. The new test holds a request inside the handler, cancels the serve context, and checks that serveNano is still running 200 ms later, that the held request then gets its answer, and that serveNano returns 0. Replacing the graceful shutdown with Close fails it. |

fix(nano): quote and cap the request log line
felis nano logged every request with the raw RequestURI and %s. That text is the caller's: a right-to-left override reordered the line as displayed, an invalid UTF-8 byte made journald store the entry as a binary blob that journalctl -f shows as "[N blob data]", and a query near net/http's one-megabyte limit became a one-megabyte log line. The URI is now capped at 256 bytes, several times a real hasJoined query, and printed with %q, so control, bidi and invalid bytes appear escaped. The handler assembly moved into nanoHandler so the logged handler can be tested on its own; cmdNano serves it unchanged. The new test sends a query carrying U+202E, a 0x9b byte and 4 KiB of padding, and expects a valid UTF-8 line with the override escaped and no more than twice the cap. Restoring the old unquoted line fails it. |

fix(config): refuse auth-source tags padded with whitespace
A third-party player's UUID is hashed from the source tag byte for byte, so the tag is a permanent namespace: change it and every player of that source comes back as someone new, with their playerdata, permissions, account links and reclaim bans left behind. Nothing said so, and a tag with a stray leading or trailing space, which nobody can see in the file, loaded as a brand new namespace. Such a tag is now rejected at load, and the AuthSourceConfig doc states that the tag is permanent, case included. The charset stays otherwise open: tightening it would force existing installs to rename, which is the very thing that rekeys their players. The new test loads a tag with a trailing space, a leading space and a trailing tab through LoadNano; all three loaded before this change. |

fix(config): refuse mojang as an auth-source tag
Mojang is prepended in code as the first, identity source, and the config templates say not to list it. Nothing enforced that. A listed tag = "mojang" loaded, and nano's startup list printed it as if Mojang had been pointed at that url, while the real Mojang was still asked first. The listed entry was a separate third-party source: asked again on every login that got past Mojang, adding up to five seconds when its url was Mojang's own and it answered 204 each time. Any case of "mojang" is now rejected at load with a message saying Mojang is built in and must not be listed. The duplicate-tag check could not catch this because the built-in source never passes through it. The new test loads "mojang" and "Mojang" through LoadNano; both loaded before this change. |

fix(config): reject auth-source urls the resolver cannot query
The url check only looked for an http:// or https:// prefix. Several
shapes passed it and then left the source dead at login time: no host
("https://"), a bad port, surrounding whitespace (sent as %20 and
answered 404), and any query or fragment. The resolver appends
"?username=…&serverId=…" to the url as a string, so an existing query
swallows those parameters and a fragment hides them from the request
entirely. Each loaded green, and every login from that source failed.
The url is now parsed and must be http or https with a host, no query,
no fragment and no surrounding whitespace. Load and LoadNano share the
check. The shipped LittleSkin default and plain http:// endpoints, such
as a same-host root on loopback, still load.
The new test feeds each rejected shape to LoadNano. Against the previous
prefix check, six of the seven load; only ftp:// was refused.

fix(nano): drop oversized hasJoined parameters before asking sources
username, serverId and ip were forwarded to every configured source at whatever length the caller sent, up to the megabyte net/http allows in a request line. Velocity never sends more than a 16-character name, a 41-character signed SHA-1 serverId and a textual IP address, so only a direct caller reaches those sizes, and each such request cost one oversized upstream call per source. Any of the three over 64 bytes is now answered 204 before a source is asked, the same as a missing username or serverId. 64 bytes still leaves room for a 16-character name in multi-byte UTF-8. The subtest behind this points a source that validates anything at the handler and sends missing and oversized fields, expecting 204 and zero upstream requests, then a well-formed login that gets 200. It replaces the old missing-username case, whose only source was unreachable, so the test passed even with the guard removed. Dropping the length check now fails it on the long username; dropping the whole guard fails it on the first missing field. |

fix(nano): refuse hasJoined requests that declare a body
A GET to hasJoined with a Content-Length and no body held its connection indefinitely. The handler returned, but net/http tries to drain an unread body before it writes the answer, and nothing bounds that wait: ReadHeaderTimeout ends with the headers. One such request per socket pins a goroutine and a descriptor on nano or on felis-api's internal face. Velocity never sends a body, so any request that declares one, including a chunked one, now gets a 400 with Connection: close, which skips the drain and releases the connection once the answer is written. The new subtest writes that request over a raw socket and waits three seconds for an answer. Before the change it times out with no response at all; now it reads a 400 marked close. |

fix(nano): report failing sources instead of treating them as a no
A source that timed out, answered 5xx or 429, redirected, or sent a 200 without a usable profile was skipped exactly like one that answered 204. With nobody else validating, the login got a 204 and Velocity told the player their account is offline-mode. Nothing was logged, so a dead or mistyped source URL, or an http:// root that now redirects to https since redirects stopped being followed, failed every one of its players with no trace. Each such failure now logs the source tag and the cause; for a 3xx it names the Location to configure instead. When no source validates and at least one failed, the answer is 503, which Velocity reports as the auth servers being down and logs with the status. A source answering 204 is still a plain no, and a validating source still wins regardless of failures before it. The new subtest puts a 503 source, a redirecting source and an unreachable one each behind a Mojang that answers 204, and expects 503. Against the previous handler every case returns 204. |

fix(bootstrap): fail the nano install when the unit does not stay up
install_nano_service printed "enabled and started" straight after systemctl restart, which returns as soon as the process is forked. An upgrade that keeps an old felis.toml the new binary rejects (an [[auth_source]] without a prefix, say) left the unit crash-looping in auto-restart while the installer reported success, and every login through the proxy failed. The install now waits two seconds and asks systemctl is-active. A unit that exited is in "activating (auto-restart)", which is-active does not count as active; on real systemd a unit whose process exits 1 under Restart=on-failure reads activating/auto-restart and is-active returns non-zero, while a running one reads active/running and returns 0. On failure the install prints the unit's last 20 journal lines and stops. This also surfaces a nano unit locked out of an existing 0700 /etc/felis. The harness runs the extracted function with systemctl stubbed both ways. Without the check, the dead-unit cases fail. |

fix(bootstrap): create the nano config dir world-searchable
felis-nano runs as a systemd DynamicUser, so it can read /etc/felis/felis.toml only if others may search /etc/felis. write_nano_config made the directory with a bare mkdir -p, which takes its mode from root's umask. On a host hardened to umask 027 that is 0750: nano exits on "permission denied", the unit restarts every five seconds, and no login gets through. A missing directory is now created 0755 explicitly. An existing one keeps its mode, because the full install sets it to 0700 to protect its secrets and widening that from the nano path would expose them. A nano unit locked out that way is left for the install to report. The harness runs the extracted function under umask 027 and checks both cases. Reverting to the bare mkdir fails the first; an unconditional chmod 0755 fails the second. The mode checks skip on filesystems that ignore chmod, such as Git Bash on NTFS. |

fix(nano): cap upstream response headers at 16 KiB
The hasJoined and name-lookup clients limited the body to 64 KiB but left headers at the transport default of 1 MiB. A configured root could answer with a megabyte of headers and stall the body, holding a few MiB of heap per in-flight login for the full five seconds; enough parallel logins take down the host, and every source's logins with it. Both clients now share a transport with MaxResponseHeaderBytes set to 16 KiB. Real roots come nowhere near it: Mojang's sessionserver sends 338 bytes of headers, LittleSkin 752, api.mojang.com 327. A source over the cap fails the request and the resolver moves on to the next one. The new subtest puts a source with 64 KiB of headers and a valid profile ahead of an honest one and expects the honest player. Without the cap the padded source wins. |

chore: drop tool-name markers from source comments
Seventeen comments opened with a tag naming the tool that wrote them. The tag goes and each comment keeps its reasoning, now starting as a plain sentence. None of the reasoning changes. The AGENTS.md note in .gitignore drops the story of how the file got into the tree and keeps the one fact a reader needs: its advice to run go fmt is destructive on this CRLF working tree. Comments only; no code, build or test changes. |

fix(config): reject auth-source tags that contain a colon
A third-party player's canonical UUID is UUIDv3 over tag+":"+nativeID, and the native id is whatever the source answers. Tags were only checked for being non-empty and unique, so both "guild" and "guild:eu" could be configured. The "guild" root could then answer hasJoined with id "eu:X" and receive exactly the UUID of "guild:eu"'s player X, along with their playerdata, permissions and account links. Real native ids are 32 hex digits, so only the shorter tag's source can do this, and only when the operator has configured such a pair; when they have, it is a full impersonation. Reject a ':' in a tag at load. With colon-free tags the join is unambiguous: two different (tag, id) pairs can no longer produce the same input, since equal inputs force equal tags and duplicate tags are already refused. The tag is deliberately not narrowed any further. It is a permanent UUID namespace, and forcing an operator to rename a tag that has no colon would move every one of its players to a new UUID. The hash input and the native id are left exactly as they were, so no existing player's UUID changes. Load and LoadNano share validateAuthSources; the new test runs both against the guild / guild:eu pair and fails on the previous config.go. |

fix(nano): always relay properties as an array
sessionProfile tagged properties with omitempty, so an upstream answer of "properties": [] (or null, or no key at all) reached Velocity with no properties key. A Yggdrasil root may legitimately answer that way for a player without a skin. Velocity 3.5.1's GameProfile deserializer passes the missing key on as null and ImmutableList.copyOf throws, so that player hangs at login with nothing logged, even though the same answer sent straight to Velocity is accepted. Mojang always sends textures, which is why the premium path and the hardware runs never hit it. Drop omitempty and replace a nil slice with an empty one before the response is written. Removing omitempty alone is not enough: a nil slice marshals as null, which Velocity rejects the same way. The new subtest feeds the relay [], null and a missing key and expects "properties":[] every time. The previous handler fails all three. |

fix(nano): stop following redirects from upstream Yggdrasil roots
authHTTPClient kept net/http's default redirect policy, so a configured third-party root that answered hasJoined with a 3xx made this host fetch whatever URL it named, up to ten hops. That is a blind SSRF into anything the host can reach, and it includes the multiplexer's own listener: a root that redirects back to /session/minecraft/hasJoined re-enters the handler, which queries Mojang and every source again and gets redirected again, until the outer 5s client timeout fires. With a 50ms Mojang stub, one login produced 86 nested handler calls and 86 Mojang requests from this host's egress IP. The loopback default does not help, because the redirect target is resolved from this host. Return the 3xx as the response instead. resolveHasJoined already skips any non-200 answer and closes its body, so a redirecting source is now treated like one that is down, and the next source gets its turn. The same probe now makes one handler call and one Mojang request. Neither Mojang's nor LittleSkin's hasJoined redirects. The new subtest puts a redirecting root ahead of an honest one and checks that the redirect target is never contacted and the honest source's player is returned. The pre-fix handler fails it. |

fix(bootstrap): keep the operator's auth sources across re-runs
write_felis_toml regenerates felis.host.toml and felis.pod.toml with a wholesale `cat >`, and the [[auth_source]] list was a literal LittleSkin block in that heredoc. Re-running the installer, which is also what `felis setup` does, threw away any edit to the list: a root the operator added stopped admitting logins, and a root they removed came back. The generated comment invited exactly that edit. Carry the tables forward the way [smtp] already is: read every [[auth_source]] table from the existing felis.host.toml (falling back to felis.pod.toml) and emit the LittleSkin default only when there is no earlier file at all. An earlier file with no tables stays empty, because that is a Mojang-only server rather than a missing value; felis-api now treats an empty list that way. The file header and the comment above the list now say what survives a re-run, and point at felis.host.toml, which is what the next run reads. bootstrap_test.sh extracts the new function from bootstrap.sh and checks the fresh-install default, an operator's own table carried without the default or the following section, an empty list staying empty, and the indented form the setup TUI writes. It passes under dash with gawk and with mawk; forcing the function to always return the default fails five of the new cases. |

fix(api): relay Mojang logins when no auth source is configured
felis api wired the hasJoined multiplexer only when felis.toml had at least one [[auth_source]]. With none, the source list stayed nil and every hasJoined answer was a 204. That was harmless while nothing pointed at the route, but the installer now starts Velocity with -Dmojang.sessionserver aimed at felis-api unconditionally, and the generated felis.toml tells the operator to delete the LittleSkin block for a Mojang-only server. Doing exactly that turned every login away, premium accounts included, and felis-api logged nothing about it. Always build the list through authSourcesFromConfig, which prepends Mojang in code, so an empty config is a Mojang-only relay. felis nano already behaves this way with the same file. The new test pins authSourcesFromConfig itself: Mojang first, the only Identity source, and still present when nothing is configured. Marking a configured source Identity makes it fail. The call site in cmdAPI is now a single unconditional assignment and has no unit test of its own. |

test: use placeholder domains in setup and system-server tests
Three tests carried the maintainer's production root domain, a personal mailbox and the public IP of a live demo host as fixture values. None of them needs the value to be real: the re-domain test only needs two different roots, and the setup flow only needs a well-formed address. Swap them for the placeholders the rest of the suite already uses (mc.example.net, [email protected]), and move the "before" root in the re-domain test to 203.0.113.10.nip.io. That address is from the RFC 5737 documentation range, so the stale install the test models still has an IP-derived hostname, which is the case the refresh exists for. |

ci: stop running the whole suite twice on every pull-request push
The header of this file argues that release.yml must not be repeated here,
because a private repository is billed twice for one answer. The push trigger
it shipped with then did exactly that: `branches: ['**']` plus `pull_request`
means a branch with an open PR runs everything once for refs/heads/<branch>
and once for refs/pull/N/merge. The concurrency group is keyed on github.ref,
which differs between the two, so neither cancels the other. Visible on this
branch's own checks: go 3m14s and go 3m3s, shell 7s and 7s, panel 25s and 24s.
Limiting the push trigger to main keeps both gates that matter -- a PR is
still checked before merge, main is still checked after -- and drops only the
duplicate. The one case that loses coverage is a branch pushed with no PR
open, where nothing has asked for the answer yet.
Verified by parsing the result with the repository's own sigs.k8s.io/yaml:
triggers are {"pull_request":null,"push":{"branches":["main"]}} and the three
jobs go/panel/shell are intact. Worth recording for the next person who
parses a workflow: YAML 1.1 reads the bare key `on` as the boolean true, so
it arrives as the string "true" after the YAML-to-JSON conversion, and a
struct tag of `json:"on"` silently matches nothing. GitHub's own parser does
not have this problem; a local check of the triggers does.

feat(bootstrap): refuse to install an unverified Velocity fork jar
FELIS_VELOCITY_FORK_JAR replaces the proxy every player connects through, and the only thing checked about it was that the path pointed at a readable file. A truncated copy, a stale build left at the same path, or the two-patch jar where the three-patch one was meant all installed silently. It now requires FELIS_VELOCITY_FORK_JAR_SHA256 and refuses on a mismatch, hashing stdin rather than the path for the reason install_via_plugins already documents: sha256sum escapes its output line for a filename carrying a backslash or newline, and the leading "\" that adds fails every comparison. The absent-digest refusal prints the jar's actual hash, so the first run after a deliberate rebuild is one copy-paste rather than an investigation. The comparison ignores case and internal spaces. The fork is built on a developer machine, which is usually Windows, and nothing there prints a digest the way sha256sum does: Get-FileHash returns uppercase and certutil has shipped the bytes space-separated. Comparing raw would refuse two of the three spellings of the correct answer and word the refusal as tampering. No digest is hardcoded, which is the half of the request this does not deliver. The fork is built from Felis-Legacy and has never been reproduced on a second machine, so a constant here would pin one machine's output rather than the fork. The comment that previously asserted the build "is not byte-reproducible" is gone too -- it was stated more confidently than the evidence supports. The fork jars on disk carry Gradle's constant 1980-02-01 entry timestamps, so the usual reason a jar differs between builds is already absent; that is not proof it reproduces, and neither claim should sit in the script unmeasured. This is deliberately not a supply-chain signature and the comment says so: an operator who can write the jar can write the digest. What it buys is that a path stops being an identity, and that every later re-run re-checks the same build. Scope: the fork jar only. The else branch still curls stock Velocity from PaperMC with no verification at all, and that is the branch a default install takes. The digest is already in hand there -- Fill v3 returns checksums.sha256 and its download URL is content-addressed on that same value -- and papermc_latest_jar discards it. Left alone rather than widened into this change. deploy/bootstrap_test.sh covers the gate's two refusals, its happy path, and the two Windows digest spellings. Each case extracts the block under test out of bootstrap.sh with awk and runs it with die/log stubbed, rather than transcribing it -- a transcribed copy passes forever after someone edits the original. The extraction is length-bounded: awk runs an unmatched end pattern to EOF, which would quietly feed the rest of bootstrap.sh to the shell under test. bootstrap.sh itself cannot run here; it wants root, a package manager and k3s. A `shell` CI job runs that plus a syntax check over every tracked script. The syntax step dispatches on each file's shebang instead of running `sh -n` across the board. The blanket form looks fine and is a false green: on a developer machine `sh` is usually bash and accepts everything, while the runner's `sh` is dash. Verified against the real thing rather than an approximation -- inside ubuntu:24.04, where /bin/sh is /usr/bin/dash, the dispatching loop passes all six scripts and the blanket loop dies at bootstrap.sh:191 on the first of its 14 arrays.

feat(bootstrap): make the legacy-forwarding backend list overridable
Which backends receive their forwarded identity through the handshake address --
rather than proxy-wide modern forwarding -- was the literal string "legacy18",
assigned inside write_velocity_service. Standing up a second protocol-47 backend
therefore meant editing this script, on every host, and remembering to.
It is now FELIS_LEGACY_FORWARDING_SERVERS, defaulting to legacy18, declared beside
FELIS_NANO_LISTEN and documented in the Tunables block like every other knob. The
default is unchanged, so an existing install re-runs to the same systemd unit it
already has.
This is deliberately only half of what the list should eventually do. It is a JVM
system property, read once when Velocity starts, so it is fixed for the life of
the proxy process and a change still needs a restart -- an environment variable is
as far as a startup property can be pushed. Having the list follow the
MinecraftServer CRs is a larger change than it looks: the forwarding decision is
made by the fork's patch to Velocity core, not by the Felis plugin, so core would
have to read state the plugin owns and refreshes. The plugin already maintains a
dynamic backend registry, which is where that state would come from, but the
bridge from core to it does not exist. The comment at the assignment now says so
instead of leaving "the upgrade path is to have the operator render this list from
the MinecraftServer CRs" as though it were a small step.
The -D is now double-quoted in ExecStart. The fork trims each element -- it parses
the property as `split(",")` into a Set, mapped through String::trim with empties
filtered -- so it accepts "legacy18, legacy112", but systemd splits ExecStart on
whitespace before java sees it. Unquoted, that spelling handed java a stray
"legacy112" argument and the unit failed to start; documenting the knob as
comma-separated without quoting it would have shipped that as a footgun.
`bash -n` passes; the default resolves to legacy18, an override to the value given,
and a value containing a space renders inside a single quoted ExecStart item.

docs(nano): drop the promise of a felis setup --nano that should not exist
nano.go's package comment told the reader that `felis setup --nano` installs the multiplexer as a service. No such flag has ever existed -- `felis setup` defines only -config and -dev -- so anyone following the comment gets "flag provided but not defined: -nano" and exit 2. Adding the flag was the obvious reading, and it is the wrong one. setup does not install anything selectively: it re-images the host by running the full bootstrap TUI, and no install-mode parameter is threaded anywhere -- nothing in Go reads or writes FELIS_INSTALL_MODE, which is a shell variable bootstrap.sh consumes on its own. So `--nano` could only mean one of two things. Re-run the installer in nano mode, which is what pointing at the installer already does. Or convert a provisioned full host into a nano one, which means tearing down k3s, Postgres and the proxy -- an uninstall, not a flag. setup's --dev already settled this shape once. It looked like a channel selector, silently installed release, and the fix was to refuse it and name the installer rather than pretend to choose. The same answer applies here, so the comment now names the real entry point -- the installer's `[2] Felis-nano` prompt, or FELIS_INSTALL_MODE=nano -- and records why there is no flag, so the next reader does not reopen it. No refusing --nano flag is added: --dev exists because it used to be a silent no-op that people passed, and nothing has ever accepted --nano, so flag's own "not defined" error is already the correct and clearer failure. |

docs: index the deferred integration seams and correct two stale markers
INTEGRATION-ONLY and KNOWN-LIMITATION are grep-able, but the grep answers the wrong question. Thirty-four Go sites share the two markers and they carry four different meanings: "declared, nothing implements it" reads exactly like "implemented, only its I/O is unreachable from here", and neither reads differently from a limitation that was accepted on purpose and is not coming back. docs/deferred-seams.md sorts them, following the bucketed shape internal/updater/doc.go already uses for its own package rather than starting a second convention. Sorting them turned up two markers that had outlived the condition they describe. config.go called the modpack upload transport a deferred integration after both backends had shipped -- LocalContextStore and S3ContextStore, selected in cmd/felis by the shape of user_uploads_context, with the uploads PVC mounted and the felis-uploads-s3 Secret rendered. What is still deferred is the far end: Kaniko reading that context from inside the build Pod. updater/doc.go listed the `felis update` CLI and the off-cluster Velocity jar read under REMAINING INTEGRATION. Both exist -- cmd/felis/update.go, and gatherer_host.go, which answers Velocity from the installed jar's manifest and felis-api from the running binary's build stamp. The two nil seams that bullet also names are real, but they belong to the in-cluster gatherer only, so the bullet now says which caller has what and which is still empty. The index also records the collision that makes a naive grep misleading: docs/troubleshooting.md uses [INTEGRATION-ONLY] for something else, defined in its own opening at :19 -- the symptom is produced by the kubelet, kaniko or a live handshake, so it cannot be reproduced from the repository. Those twelve marks say where a failure comes from, not that something is unbuilt, and are excluded. Both code changes are comments. Every file:line the index cites was checked against the line it points at. |

fix(crd): remove spec.storage.retainOnDelete rather than leave it inert
The field validated, shipped in the CRD, and reached no controller. The world PVC survives deletion unconditionally -- it is a StatefulSet VolumeClaimTemplate, StatefulSet deletion does not cascade to template PVCs, and no finalizer exists anywhere in the operator. So setting it true described what already happened, and setting it false did nothing at all. False is the worse half: it reads as a request to delete a world, and was silently ignored. This departs from spec v4.1 §5, which asks for "删除:finalizer 清 Service/STS/ConfigMap,PVC 按 retainOnDelete". Neither half was ever built. Restoring that line means adding a finalizer whose other listed duties -- Service, StatefulSet, ConfigMap -- ownerReference GC already performs, so the only work it would newly do is delete worlds, on a path that does not pass the reaper's verified-backup check. The reaper is the one thing in the system allowed to destroy a world and it earns that by proving a backup first. A second door without that check is not an improvement. The spec is a frozen versioned document, so it is left alone and the departure is recorded in troubleshooting.md §13, beside the behaviour it explains. §12 loses its inert row and its opening sentence, which existed to introduce this one field: every field in that table is now read by a controller. Deployed installs need nothing. A CR still carrying retainOnDelete keeps working, because a v1 CRD prunes unknown keys on the next write and the behaviour the field claimed to control was never conditional. go build, go vet and go test ./... pass on Linux with zero failures; the CRD still parses and storage keeps size and storageClassName. |

ci: run the checks on push and pull request
release.yml was the only workflow and it fires on v* tags, so `go vet` and `go test` first met a change once that change was already on the release path, where the only remedy is another tag. The panel suite ran nowhere at all: a release goes through the Dockerfile and the Dockerfile runs `npm run build`, never `npm test`. 111 assertions across 8 files existed and nothing outside a developer's checkout ever executed them. Both jobs are green as of this commit, checked before writing it rather than after: go vet and go test ./... (24 packages, 0 failures, on Linux), npm test (8 files, 111 tests) and npm run typecheck. A gate that lands red is a gate everyone learns to ignore. The panel's Node version is read out of the Dockerfile instead of repeated here. `FROM node:<major>` is the only place the tree declares it -- no .nvmrc, no engines field -- so a copy in this file would keep testing 22 the first time the image moved. That is the class of drift this workflow exists to catch, not to introduce. The step fails loudly if the FROM line stops matching. Tags are excluded from the push trigger. A v* push already runs release.yml, which repeats the Go job, and this is a private repository billed for both. |

docs(plugins): say which plugin jars an install actually produces
The module table listed felis-fabric, felis-forge and felis-neoforge next to the two jars a finished install really has, with nothing distinguishing them. Neither deploy/bootstrap.sh nor the embed set in bootstrap_asset.go builds a loader mod, so someone reading the table expected three jars that are not there after setup and had no way to tell from this file. The mods do build -- the wrapper commands under Building work -- they are just never installed for you, which is what the new column says. Two further disagreements with the code, in the same table: limbo/ was missing entirely. It is embedded, built by bootstrap.sh and running on the login gate, so the one module the table omitted was a shipped one. It is also the only module that reaches the account-link endpoint without a command: it mints the code on join for anyone unlinked and holds them until they redeem it, so the opening claim that every module except the lobby ships /link named the wrong exception. velocity was listed as felis-velocity-0.2.0.jar; plugins/velocity/build.gradle:6 says 0.1.0, as does every other module. Nothing breaks on this because bootstrap.sh globs felis-velocity-*.jar and installs it under a fixed name, but the version in the table was not a version anything produces. The Gradle table and the JDK note now carry limbo's Java-21 toolchain, which it needs for the same reason paper does and for a different cause: LOOHP/Limbo releases are class-file major 65, so the compiler JDK must be able to read them. It still emits release 17 bytecode. |

docs(troubleshooting): correct four fields the runbook documents as inert
Sections 11 and 12 told the operator that idle auto-stop, both startup budgets, and the player tally are read by nobody. All four are read, and §1 repeated the same claim in its strongest form: "the operator has no start timeout ... loops forever". spec.idle.autoStopEnabled reconciler.go:175 spec.idle.emptySecondsBeforeStop reconciler.go:175 spec.startup.timeoutSeconds reconciler.go:479, called at :126 spec.startup.readinessTimeoutSeconds reconciler.go:490, called at :157 status.players.online reconciler.go:413 (markRunningReady) The repository already contained the disproof: TestReconcileRunning_StartupTimeoutConvertsToFailed and TestReconcileRunning_ReadinessTimeoutConvertsToFailed both assert the escalation §1 said does not exist. The test §1 cited, TestReconcileRunning_RconProbeFailureStaysStarting, only asserts that a single failed probe does not flap the phase; that was read as "forever". §11 was the costly one, because it misdiagnosed a configuration problem as a missing feature. Idle auto-stop and the player tally both hang off spec.rcon.enabled -- the tally is a by-product of the RCON readiness probe (prober.go:63 runs `list`), and reconciler.go:175 carries the RCON condition explicitly so a never-sampled zero cannot stop a server full of people. Following the old text, an operator whose RCON was never enabled would conclude the feature was unwritten and stop. The section now opens with the jsonpath that reads spec.rcon.enabled. Also separated the prober's fixed 5s dial timeout (prober.go:45) from spec.startup.readinessTimeoutSeconds, which §1c conflated: the former bounds one probe, the latter is a deadline for the whole start measured from status.startRequestedAt. spec.storage.retainOnDelete is the one field still genuinely inert, so the [INERT] legend and §12 stay -- §12 now records the condition each read field depends on instead of claiming none of them are read. |

build: pin line endings to LF so the embedded bootstrap.sh ships without CRs
The repository had no .gitattributes. With core.autocrlf=true a Windows checkout handed deploy/bootstrap.sh 2374 CRs, and bootstrap_asset.go embeds that file from the working tree verbatim, so a dev-built felis piped a CRLF script into `bash -s` on the target host. CI builds on Linux, which is why released binaries were clean and only local builds carried it. eol=lf is global rather than scoped to *.sh because go:embed reaches further than the installer: deploy/*/Dockerfile, deploy/*/entrypoint.sh, plugins/*/src, the migrations and internal/panel/static are all compiled in and read on Linux. *.bat is the one exception, for the gradle wrappers' Windows launchers. Renormalizing the index touched exactly one tracked file, cmd/felis/version.go, and only its line endings: `git diff --cached --ignore-cr-at-eol` reports nothing outside .gitattributes itself. TestBootstrapPinsViaBlockConnectionsOff used to strip \r\n before asserting, with a comment stating that the repository pinned no eol attribute. That is no longer true, and the stripping hid the regression this commit prevents. It now asserts the absence of CRs, so losing the attribute reports itself as line endings rather than as a missing serverside-blockconnections pin. Closes #5 |

feat(operator): make any Paper image joinable behind the forwarding proxy
Velocity modern forwarding is proxy-WIDE. A backend that cannot verify the signed handshake does not degrade -- it rejects every login the proxy forwards. Until now the only backends that could verify it were the two images Felis builds itself (deploy/limbo, deploy/lobby), which read FELIS_FORWARDING_SECRET in their own entrypoints. An arbitrary Paper image a user brings does not, so it passed admission, started, reported Ready, and was UNJOINABLE. The platform's answer was to recommend the lobby image as a base for a user's own world (0018_recommended_images.sql), which was never a good base -- it carries the /menu plugin whose job is to TRANSFER a joining player away, the exact opposite of a server you mean to stay on. The fix configures forwarding from OUTSIDE the image instead of requiring it inside. The operator now injects a root `felis init-forwarding` initContainer into every user server; it writes the proxies.velocity block into config/paper-global.yml and forces online-mode=false in server.properties on the /data PVC before the main container starts. The image needs no forwarding logic of its own, so the joinable set stops being "images that self-configure forwarding" and becomes every Paper-family image the platform runs. buildStatefulSet gates the injection on the ABSENCE of the system-role label: the Felis-built system servers already consume the secret in their entrypoints and the login gate is a limbo, not Paper. It is also gated on a non-empty felis image name -- the operator Deployment passes its own image as FELIS_IMAGE, and an operator without it skips the injection rather than failing, because a cluster whose proxy is not in modern mode has nothing to configure. The init runs as root deliberately. The world volume's ownership comes from the storage provisioner and the main container runs as whatever UID its image declares, so root is the only UID that can reliably write these files; it then chmods them 0666/0777 so that non-root main container can rewrite them on boot. The privilege is bounded -- the init exits before the server container starts and the server container keeps its own UID. The alternative, an fsGroup on the pod, is noted in the code as the upgrade path if the init ever stops running as root. The writer merges rather than overwrites, both because Paper expands paper-global.yml to its full default tree on first boot and because the panel file editor may edit either file between boots. It sets proxies.velocity.* and the single online-mode key and leaves every other setting alone. It is a no-op on an empty secret, for the same reason the env var is optional: a proxy that is not in modern mode provisions no Secret, and wedging every server's init on a missing optional value would be worse than the status quo. felis-paper (deploy/paper) is the platform's plain-Paper expression of that base and 0019 seeds it recommended: same PAPER_JAR_URL the lobby build already resolves, no /menu plugin, no forwarding gate, and a correctly-escaped RCON channel so the console, the online-player list and permission commands work out of the box. 0018's row is left in place -- an admin who kept it can keep it; this only adds the better default beside it. Three fixes ride along, each of which the 1.8 path hit in practice. bootstrap pins ViaVersion's serverside-blockconnections off. ConnectionData.init() only builds its block-connection provider when Via's lowest supported protocol is below 1.13; under modern forwarding the Velocity injector reports 393, so init() returns early, blockConnectionProvider stays null, and the first 1.12.2->1.13 chunk rewrite dereferences it -- a 1.8 client takes an NPE on the first chunk it is sent and never finishes joining. Every call site is behind isServersideBlockConnections(), so switching it off skips all of them, at a cosmetic pre-1.13 cost: fences and glass panes stop drawing connected. ViaVersion ships the option ON, so a fresh install shipped that NPE. Seeding a file with this one key suffices -- Config#loadConfig parses the bundled default as the base map and merges the on-disk file over it, so every other option stays current across version bumps. The absence of "Loading block connection mappings" in the log is NOT evidence this worked: init() gates on the protocol version too, and that half fails on its own, so the line is missing either way. The config value is the only evidence, which is what the test asserts. The Velocity unit gains -Dfelis.legacy-forwarding.servers=legacy18. A protocol-47 backend sits behind ViaVersion, which strips modern forwarding's login-plugin-message when it down-translates the proxy->backend pipeline to 47 -- the packet is registered from 1.13 and has nowhere to go. Only the handshake address field survives Via, so the Felis fork forwards the named servers BungeeCord-style while every other backend keeps modern+secret untouched. v1 hardcodes the one legacy backend; rendering the list from the MinecraftServer CRs is the upgrade path. deploy/lobby's set_prop escapes the value before substituting it. The RCON password is operator-provisioned arbitrary bytes, and a '|', '\' or '&' in one corrupts a bare `sed s|...|...|` and silently kills the key -- taking the console, the online-player list and permission commands with it. deploy/paper was written with the escaping, so the lobby gets the same rather than leaving the sibling caller broken. Verified: the full Go suite passes on Windows and on Fedora 44 (go1.26.4), where TestWriteForwardingFileModes actually runs its POSIX mode assertions instead of skipping. The new tests cover the initContainer's image, root UID, world mount and secret env; the merge preserving unrelated config trees; the properties upsert including the commented-key case; and the bootstrap script both writing the Via key and still calling the function that writes it. Not verified: the initContainer has never run in a real cluster, and the felis-paper image is code-only here as the other game-stack images are -- no Go CI builds them. The ViaVersion pin is the one piece with live evidence, and that evidence is what it was written from. Before it, a client was cut within a second of "logged in with entity id" on legacy18 while the proxy logged the NPE above -- REMAP OF LEVEL_CHUNK chained into Protocol1_8To1_9's MAP_BULK_CHUNK. It was applied by hand to the running proxy on 2026-07-24 at 14:47 and only then written back into bootstrap. At 14:48:14 the same player joined real Paper 1.8.8 through the fork, issued commands, approved an op-login from in-game at 14:50:39, and held the connection until 15:30:09 -- 42 minutes. Neither session says which client version it was. The proxy never logged a protocol number. It bounds above at 1.16.4, from the viabackwards "(1.17->1.16.4) ... for 1.16 players and below" warning that fired for that player on the lobby leg, and no lower -- Via floors every handshake to the proxy's 393, so anything from 47 up is admissible. Reading Protocol1_8To1_9 in the stack as a client-version tell is backwards: that chain runs on the BACKEND leg, up-translating the 47 server's chunks to the floor. What the NPE proves is that the pin was load-bearing, not who was holding the mouse. That is one hand-run session on one host, and it is not a cell. The 393->47 leg has one now, in Felis-Legacy -- FL-009 puts a genuine protocol-47 client on a stock Paper 1.8.8 behind this proxy and flips this same option: on it, cut 0.2s after JoinGame with the fault above; off, holds. No automated test in THIS repository exercises the leg. |

feat(bootstrap): allow the Felis-Legacy Velocity fork to be installed as the proxy
Stock Velocity will not offer the login-plugin-message exchange below 1.13, so a 1.8 client reaching a modern-forwarding backend today is a side effect of Via replacing the channel initialisers before that check runs. It works, and nobody designed it. FL-008's fork registers the two login packets from 1.7.2 and drops the handshake gate, which makes the same outcome deliberate — and its gateonly control shows the registry half is the load-bearing one. FELIS_VELOCITY_FORK_JAR points at such a build; unset, the default, nothing changes and the stock 3.5.1 download runs as before. It stays opt-in because the fork is unmeasured where it counts: FL-008's probe runs offline-mode against a stub backend, while this jar would carry every real Mojang session on the server. No digest is pinned for it. The gradle build is not byte-reproducible across machines, so a hash here would assert a provenance that does not exist; the jar is trusted because that probe certified a build, and the path is checked for readability before anything is replaced. |

fix(velocity): stop the lobby tile failing for players already in the lobby
Asking for the server you are standing on is a no-op, but it went through the whole wake-and-queue path and ended in a Connect to the current server, which Velocity answers ALREADY_CONNECTED. The player saw a failure for a move that was never real. The guard belongs in authorizeAndWait rather than at each entry point: the menu tile, /felis go and an accepted invite all funnel through it. The lobby is where it shows up most, since the tile for the lobby itself sits in front of every player already standing in it. |

fix(velocity): pin ViaRewind 4.1.3, the release that matches ViaVersion 5.11.0
The previous commit staged ViaRewind 4.1.2 alongside ViaVersion and ViaBackwards 5.11.0. The staging mechanism was right; the pairing was not. On startup the proxy logs ERROR [viaversion]: Error during loading of Protocol1_9To1_8 java.lang.IllegalArgumentException: Invalid version: 1 and Protocol1_9To1_8 is the one protocol every 1.8 client needs. Without it a 1.8 player clears the handshake gate we just opened and then lands on a translation layer that never initialised. The three versions are a set, not three independent pins. ViaRewind 4.1.3's release notes state it adds compatibility with ViaVersion and ViaBackwards 5.11.0; 4.1.2 predates that. Measured rather than assumed: a two-arm run of the same proxy image, same velocity.toml, same ViaVersion/ViaBackwards jars, differing only in the ViaRewind jar, logs the error three times on 4.1.2 and zero times on 4.1.3. The full FL-007 forwarding matrix was re-run against 4.1.3 rather than inferred from the two-arm result — a different jar is a different configuration under test. It closes 20/20, including the three force-key-authentication assertions, with the proxy log confirming "Loaded plugin viarewind 4.1.3" and no Protocol1_9To1_8 error. Still unproven, and deliberately not claimed here: a real 1.8.9 client authenticated against Mojang. The harness has no Mojang account, so online-mode = true remains the one untested axis. |

feat(velocity): let 1.8.x players through the modern-forwarding proxy
Felis pins player-info-forwarding-mode = "modern", and Velocity's HandshakeSessionHandler#handleLogin refuses anything below 1.13 outright: it reads handshake.getProtocolVersion() and disconnects with velocity.error.modern-forwarding-needs-new-client before the backend is ever contacted. A player pinned to 1.8.9 never reaches the login gate, never sees the onboarding link, and gets an error string that tells them to upgrade their client. install_via_plugins now stages ViaVersion, ViaBackwards and ViaRewind into /opt/felis/velocity/plugins alongside felis-velocity.jar. Nothing else moves: same forwarding mode, same secret, no backend patched and no backend downgraded. The 1.13 floor turns out to be a property of the unassisted proxy pipeline rather than of the forwarding protocol, so lifting it costs three jars and no source change. This was measured, not assumed. Felis-Legacy's FL-007 probe stands a protocol-47 client in front of a stock Paper 1.21.11 backend behind a modern-forwarding proxy and watches it join. The proof is the join itself rather than the log line: that backend runs velocity.enabled with a shared secret, and Paper in that state rejects any login not carrying forwarding data signed with a matching HMAC. The control cell without Via is rejected before the backend is contacted, so Via is the only difference. A second cell re-runs the same join with force-key-authentication = true, the way Felis sets it, because a result that only holds under a config Felis does not run is not a result about Felis; the 1.19+ signed chat key a protocol-47 client cannot produce is never demanded, and it cannot be, since the pre-1.19 wire format has no player-key field to decode. The jars are pinned by sha256 and not by a moving tag. They sit in front of every packet on the proxy and they are the exact bytes FL-007 measured; "latest" would quietly make this an unmeasured configuration. The digests come from the GitHub releases FL-006 locked, which is deliberate — Hangar's VELOCITY/download endpoint serves different bytes for the same version numbers, so an installer that only checked for HTTP 200 would ship artifacts nothing has tested. A version bump means a digest bump here. Two limits are worth writing down. Only protocol 47 was measured; the rest of Via's documented 1.7-1.12 range is inference from that one point. And the probe runs online-mode = false because it has no Mojang account, so Felis's online-mode = true is untested — the untested part is the Mojang auth handshake specifically, which puts the residual in Via's own login handling rather than in forwarding or in the hasJoined multiplexer, whose request is protocol-independent. Checks: a fresh install lands all three jars at the pinned digests and sizes with no temp files left behind; a re-run downloads nothing; a tampered jar is restored to the pinned bytes; and a deliberately wrong digest aborts without installing anything. Existing installs pick this up by re-running bootstrap, which re-enters install_velocity because bootstrap.done is written but never read as an early exit. |

docs(mail): say plainly what a green SMTP self-test does not prove
The Ping comment claimed the self-test could not produce a false negative and left the impression it therefore proved deliverability. It does not, and the distinction is the whole trap: a relay that gates sender identity at end-of-DATA gates it on the way OUT. Fastmail answers 250 for [email protected] addressed to the account's own mailbox and 551 5.7.1 "Not authorised to send from this header address" for that same From addressed to anyone else — and only the account's exact authorized identity passes the second one, another local-part on the same domain is refused too. So a green Ping means connect, TLS, AUTH and message shape are good, and nothing more; the operator still has to have authorized From as a sending identity with their provider, and the first real OTP is what proves they did. Addressing the self-test somewhere external would not fix it either — the only mailbox an operator can reliably check is usually inside the same account — so the honest move is to scope the claim rather than buy false confidence with a bigger probe. |

fix(api): log the panic value and stack behind the opaque 500
withRecover turned a panicking handler into a 500 envelope and threw the panic away. The client is meant to get an opaque "internal error" — that part is right — but nothing was written server-side, so a recovered panic was an untraceable 500: an operator holding "internal error" has no message, no stack and no request to grep for, and diagnosis degrades into guessing against a live install. That is what it cost during the email-OTP report. The panic value, a stack and the method+path are now logged first, keyed by the same request_id writeError already stamps on unmapped errors, so the client envelope and the server log can be joined. The test pins all three markers plus the unchanged 500/"panic" response, because a silent recover looks exactly like a working one from the outside. |

fix(setup): stop the forced-onboarding gate trapping players who have no email
setup_required is what the SPA polls to decide whether the onboarding wall is still owed, and it disagreed with the middleware that actually enforces the wall. requireOnboarded lifts on a verified email OR an enrolled passkey; setup_required answered `u.Email == "" || !hasPasskey`. A console-tier player joins through the bind-code door with no email at all — by design, there is no SMTP at that point — so the email term never clears and the SPA keeps them on the setup screen forever, even after they enroll the passkey that already unlocked the API for them. The predicate now lives in one place (setupRequired) and both endpoints call it, so the next edit to the unlock condition cannot drift them apart again. Keying it on EmailVerified rather than email presence is the deliberate part: presence is exactly the term that trapped the no-email player, and it was also wrong on its own terms — an unverified address is not an authentication factor, so it was never what the lockdown could safely lift on. Also lands the regression test for the mechanism behind the live claim-403 report: /me/servers answers 200 for a bind-onboarded player (which is why the dashboard renders the 认领 button at all) while claim, wake and status all answer 403 with code "setup_required" — i.e. the refusal comes from requireOnboarded before the handler, not from isOwnerOrAdmin inside it, which would have said "forbidden". Enrolling a passkey and changing nothing else lifts all three, which isolates the gate as the sole cause. The backend authz is correct; the button that leads a locked-down player into a 403 is the frontend's to hide. |

feat(invite): let a player bring a friend to the server they're on
/invite <player> posts a chat card to the invitee with a green [Accept] and a red [Deny] button, and Accept walks them to the server the inviter is standing on. It is a UX wrapper over `/felis go` and nothing more: the accept runs the same doGo path on the ACCEPTING player's own verified uuid, so a stored invite carries a server name and never an identity to act as, and the prompt needs no unguessable token. Why it can be this simple: an invite can only name the server its sender is currently on, so the target is running by construction, and a running felis server already admits any linked player through <name>.<root-domain> on the link check alone (WaitingRouter.onServerPreConnect) — no wake, no autostartPolicy consultation. Hence enqueueFromInvite: a READY backend is joined directly, and only the not-ready case falls through to the policy-gated wake path unchanged. Routing an accept through wakeAndWaitLinked would have asked the API to wake a server that needs no waking, and autostartPolicy defaults to ownerOnly, so the API would answer 403 and the green button would do nothing for exactly the people you would invite. It is not consequence-free, and the inviter is told so at send time rather than in a comment only we read. Landing on a felis server records the player in its allowlist (onServerConnected -> join-event -> RecordJoin); on an autostartPolicy=allowlist server that row is what lets them come back and START the thing later. The same row they would earn by walking in unaided — the invite shortened the walk, it did not widen the door — but it outlives the invite, so accessNotice says so. The wording follows the policy: only under allowlist does it claim they will be able to start the server themselves, because under the ownerOnly default (and the empty string the API reports for an unset field) that row grants no waking and the claim would be a lie. InviteBook also holds a 30s per-sender cooldown, because the one capability /invite genuinely adds is "make a chat card appear on any online player", and unrated that is a way to follow someone around their own chat log. It is charged in put() rather than at the top of the command, so an invite refused for an offline name or a player already on the server costs the sender nothing, and the gate sits after every other validation for the same reason. The stamp is global per sender on purpose: a per-(sender, invitee) key would wave through one player papering the whole proxy, which is the thing being limited. The card lives in InviteCard as a pure function so the buttons — the whole point of the feature — can be asserted without a live proxy, and the button clicks are pinned to the server the card named, so a stale card cannot answer a newer invite (checked with peek before the invite is spent, so refusing a superseded card leaves the live one answerable). Verified: production gradle 8.14 + JDK 21 build; jar carries the plugin classes and no test classes; InviteBookTest (36 checks) and InviteCardTest (48 checks); and a live Velocity 3.5.1 that loads the jar, registers /invite <player> and answers /invite accept <server>, with a malformed subcommand as a negative control. |

fix(setup): stop the login gate sending players to the old console after a re-domain
Changing root_domain updated felis.toml and the panel, but the login gate kept pointing players at the hostname it was created with. FELIS_ROOT_DOMAIN and FELIS_PANEL_HOSTNAME are baked into the login MinecraftServer at provisioning time, FelisLimboPlugin reads them to build the link an unauthenticated player is told to open, and ensureSystemServers is create-if-absent — so nothing in the install ever rewrote them. On the demo host the CR still carried console.159.223.32.51.nip.io hours after the domain had moved to mc.flyemoji.network: every joining player was handed a link that bypasses the tunnel, hits the node directly and trips a certificate warning, on the one screen someone with no account is guaranteed to see. setup now converges these values on an existing system service instead of skipping it. Create-if-absent stays the rule for everything else, and the comment on it is still true — an operator's edits to a system service must survive a re-run. These three names are the exception because they are not the operator's to own: they are a copy of config that is wrong the moment config changes, and there is no other writer who could notice. The convergence is deliberately narrow. Only a name already present with a different value is rewritten, so env the operator added by hand is untouched and the rest of the spec — image, memory, storage — is not read at all. A derived name that is absent from the live object is left absent rather than added back: a deliberate removal and drift look identical from here, and re-adding it would mean fighting the operator on every run. The outcome string reports the refresh so a setup run does not silently rewrite the front door. This closes one surface of a re-domain, not the whole of it. The write-once panel certificate at deploy/bootstrap.sh keeps its old SANs, and so do the Velocity config and the forwarding material; the warning in bootstrap.sh that says so is still accurate. What changes is that the surface players actually walk through now catches up when setup is re-run. Checks: a login gate built with the old domain converges onto the new one and says so; an env var the operator added and a hand-raised javaMemory both survive that same run; and an install whose config already matches reports no refresh, so a routine setup does not read like a re-domain. The middle one is the one worth having — converging config must not turn into a licence to clobber the edits create-if-absent exists to protect. |

feat(lobby): ship LuckPerms in the lobby image so the panel's permission controls work
The panel has a full permission surface — internal/api/handlers_access.go issues
`lp user <player> permission set/unset` and `lp user <player> parent add/remove`
over RCON, and projects the result back at
GET /api/v1/servers/{name}/access/luckperms/{player} — but nothing in this tree
ever installed LuckPerms. The lobby image copied felis-paper.jar into the plugin
directory and stopped there, so every grant the panel sent reached a server that
answered "Unknown command". Confirmed on the demo host: /data/plugins held only
FelisPaper/, bStats/, felis-paper.jar and spark/.
This is the other half of the RCON change. That one gave the control plane a
channel to send commands on; this one puts something at the far end that
understands them. Neither is useful alone.
The jar is resolved at build time rather than pinned in the Dockerfile, the same
way PAPER_JAR_URL already is: metadata.luckperms.net publishes the current build
for every platform, and asking upstream keeps this tree from going stale on every
LuckPerms release. Unlike Paper it is not version-matched to MC_VERSION — LuckPerms
ships one Bukkit build covering the whole supported Minecraft range, so there is no
per-version endpoint to ask. The resolver's pattern pins the /bukkit/loader/ path
segment deliberately: the metadata endpoint hands back the fabric, forge, velocity
and bukkit-legacy URLs in the same payload, and a looser match would happily return
a jar Paper cannot load, or the legacy build that targets Minecraft 1.8-1.12.
A missing LUCKPERMS_JAR_URL fails the build. That is a harsher default than the
RCON password, which only warns, and the difference is where the failure surfaces:
a lobby without RCON degrades visibly at once, whereas a lobby without LuckPerms
starts perfectly, runs perfectly, and only reveals itself when an owner tries to
grant somebody a permission. Build time is the cheap place to notice.
The entrypoint refreshes the jar from the image seed on every boot exactly as it
does for paper.jar and felis-paper.jar, so the executable artifact tracks the image
while LuckPerms' H2 database and config under plugins/LuckPerms/ stay on the PVC.
That split is the point: every grant ever issued lives in that directory, so the
refresh must never become a wipe.
Check: the three files that have to agree about LuckPerms — bootstrap.sh resolving
and passing the build-arg, the Dockerfile requiring that arg name and writing a
fixed path, the entrypoint copying from that same path — are pinned against each
other. Nothing compiles them together, and a typo in the path is invisible until a
lobby boots and `set -e` turns the failed cp into a crashloop on the hub every
authenticated player is transferred to. The test reads all three back out of the
embedded FS rather than off disk, since that is what the TUI install path ships.
Deployed installs are NOT fixed by this commit, for the same reason the RCON change
was not: the felis-lobby image has to be rebuilt and re-imported, and the pods
recreated, before the jar exists on the volume.

feat(rcon): provision per-server RCON so the console, player list and permissions work
A server created through the panel never had RCON. CreateServer built a
MinecraftServerSpec without a Rcon block at all, so the field took its zero value
and every downstream consumer read Enabled=false. Nothing failed loudly: the
operator skips the probe when RCON is off and marks the server Ready on pod
readiness alone, so the panel showed "运行中" for a server the control plane could
not talk to. Everything that rides the write channel (spec §8 写=RCON) was dead —
the online-player list returned nothing because Status.Players is only ever
sampled by the probe, and console writes answered 503 ErrConsoleUnavailable
because internal/api/console.go refuses when Enabled is false.
The whole RCON machinery already existed — builders gate the service port,
container port, preStop save-and-stop hook and the RCON_* env on Spec.Rcon,
the reconciler probes and reports, console.go dials, the NetworkPolicy opens
25575 to {api, operator}. The only thing missing was that nobody ever turned it
on or created a password. This wires the three layers that were absent.
Provisioning lives in the operator, not in felis-api. felis-api holds secrets:get
and not create, and giving it create solely to mint a password it immediately
stops caring about (console.go re-reads the Secret at command time) would widen
the API's powers for nothing. The operator already reads every Secret in the
namespace, so adding create there grants no read it did not have. It also makes
provisioning declarative: a Secret deleted by hand comes back on the next pass, a
controller reference garbage-collects it with the server so no delete path has to
remember it, and a server that predates RCON only needs spec.rcon filled in for
the password to appear. The name comes from naming.RconSecretName so felis-api,
`felis setup` and the operator cannot drift apart on it.
RCON is enabled per system service rather than by default, because enabling it on
a backend that serves no RCON listener is destructive rather than merely useless:
the operator gates readiness on the probe, so such a server never leaves Starting
and is eventually marked Failed. The login limbo is exactly that backend
(LOOHP/Limbo has no RCON) and it is the front door, so it stays off; the lobby
runs Paper and is administered through the panel like any other server, so it is
on.
Paper only reads RCON settings from server.properties, so the operator's injected
RCON_PASSWORD did nothing on its own — felis-lobby's entrypoint now writes the
three keys on every boot. Rewriting them each time makes the copy in the world
volume derived state rather than the source of truth, so an owner who edits them
through the panel's file editor cannot lock the control plane out of their own
server. Without a password it sets enable-rcon=false and warns rather than
refusing to start: unlike the forwarding secret, a missing RCON password degrades
the server rather than making it unsafe.
That password landing in server.properties is a §286 exposure (RCON 密码绝不下发
前端), since server.properties is readable through the file editor. It is redacted
on read rather than the file being denied outright the way config/paper-global.yml
is: the forwarding secret is cluster-wide material that merely happens to sit in
the volume, whereas server.properties is the single most-edited config an owner
has, and hiding one line should not cost them MOTD, difficulty and view-distance.
The write path is deliberately left alone — the boot-time rewrite restores the
real value, which is what makes redacting rather than denying safe here.
Also guards idle auto-stop on Rcon.Enabled. Status.Players is only meaningful
when the probe ran; with RCON off it keeps its zero value, which that branch would
have read as "empty" and used to stop a server full of people. AutoStopEnabled is
not currently settable through any path, so this is a latent footgun rather than a
live bug, but it is one line and the alternative is discovering it in production.
Checks: the operator provisions a missing Secret with a 32-hex-char password and a
controller reference, and does not rotate an existing one; idle auto-stop stays
inert without RCON; the editor redacts rcon.password from the world root's
server.properties while leaving the rest of the file (and a plugin's own nested
copy) intact; login has RCON off and lobby has it on with the shared secret name;
CreateServer sets the block. That last one departs from K8sCluster being
integration-tested against a live cluster: this defect was a struct literal
missing a field, it shipped, and a fake client is enough to pin a struct literal.
Existing servers are NOT migrated by this change — CreateServer only covers new
ones and ensureSystemServers is create-if-absent, so a `felis setup` re-run will
not touch an existing lobby. A deployed install additionally needs the
felis-lobby image rebuilt and re-imported for the entrypoint change, and its pods
recreated, before the RCON keys reach server.properties.

fix(mail): prove SMTP deliverability before saving, and stop losing the relay
A live install passed the SMTP setup screen and then failed every one-time
code with a bare `internal error`. Four separate defects had to line up for
that, and each is fixed here.
The relay was configured with `from = noreply@<domain-A>` on an account
authenticated as `<user>@<domain-B>`. Providers that validate sender identity
— Fastmail among them — answer MAIL FROM with an unconditional 250 and only
refuse at end-of-DATA. Ping stopped at NOOP, so it never saw the refusal: the
wizard reported success, wrote the config, rolled felis-api, and every OTP
afterwards died at w.Close().
Ping now runs the same transaction a real code takes — connect, (STARTTLS,)
AUTH, MAIL FROM, RCPT TO, DATA — delivering one self-test message to the From
address, and SendOTP and Ping share deliver() so the check cannot drift from
the thing it checks. The self-test recipient cannot cause a false negative:
an authenticated submission relay accepts RCPT for any destination by
definition, while the sender identity it does validate is exactly what we
want tested. The setup screen now says a message will be sent, names the
address it went to, and warns that From must be an address the account is
allowed to send as.
A relay refusal also answered 500 `internal`, which reads as a broken panel
and sends the operator hunting through handler code instead of their [smtp]
block. It is now 502 `mail_undeliverable`, mapped inside deliverOTP so all
four doors that mail a code (onboarding, email login, op-login, migrate
step-up) answer alike. The relay's own text stays out of the response — it
can name the SMTP account, and these routes are reachable by any signed-in
player — and goes to the log instead.
writeError logged nothing when it collapsed an unmapped error to 500, so an
operator holding an `internal error` had nothing to grep for and diagnosis
degraded into guessing against a live install. It now logs the method, path,
wrapped chain and the same request_id the caller is shown.
Finally, write_felis_toml regenerated the config wholesale and never emitted
[smtp], so re-running the installer — the documented way to update felis-api —
silently erased a working relay and reverted OTP delivery to the no-Mailer
path, logging codes instead of sending them. It now carries the block forward,
cached on first read because the host toml is clobbered before the pod toml is
written. Same defect family as the root_domain loss fixed in

docs(readme): give an install command that works against a private repo
The documented one-liner fetches bootstrap.sh from raw.githubusercontent.com unauthenticated, which 404s for as long as this repository stays private -- so the single command the README exists to provide did not work for anyone. The authenticated form goes through the contents API with the raw media type, matching what github_api already does, and hands the token to curl over stdin via --config rather than -H. argv is world-readable through /proc, and a token on the command line would leak to any local user during the install; bootstrap avoids that in its own fetches for the same reason and the README should not teach the opposite. sudo -E, because the installer needs that same token to resolve and download the release. Without it sudo drops the variable and the run fails later, at the release lookup, for a reason the operator has no way to connect to this command. The public one-liner stays first: it is what this becomes once the repository is public, and the note is scoped to the current state. Also records that re-running the installer is how felis-api moves to a newer release, that it now keeps the installed root domain, and that it does not keep the channel. |

fix(bootstrap): reuse the installed root domain instead of re-deriving it
detect_node_ip recomputed FELIS_ROOT_DOMAIN from scratch on every run and fell back to <node-ip>.nip.io. Nothing read the domain back out of the felis.toml an earlier run wrote, so it survived only as long as the operator kept passing the same environment. That made re-running the installer destructive on any install with a real domain, and re-running it is not optional: it is the only way to move felis-api to a newer release, which is what `felis update` points operators at. A bare re-run rewrote root_domain, panel_hostname and admin_hostname to nip.io names while ensure_panel_tls_cert returned early on the certificate it had already written, leaving the console serving a cert for hostnames it no longer answered to -- with no re-domain flow to recover through. Precedence is now explicit FELIS_ROOT_DOMAIN, then the domain the last run persisted, then the nip.io default. First installs are unaffected. Deliberate re-domains still work, because there is no other route to one, but they now warn that the write-once certificate is not reissued and that the proxy and login config carry the old name too. Secrets were never exposed to this: load_or_make_secrets has always sourced secrets.env before generating anything. The domain was the one piece of install identity with no read-back. The channel is deliberately left alone. FELIS_VERSION_BOOTSTRAP is not persisted either, but defaulting a re-run to the release channel installs a working build rather than breaking one, so cmd/felis/update.go states that instead. Its warning about the domain went with the bug and would now be false. Verified against the shipped function text: the ladder holds for a fresh host, a re-run with and without the variable set, a re-domain, and a felis.toml whose root_domain is missing or empty. Reverting the one line reproduces the nip.io overwrite. |

fix(update): say that setup cannot move felis-api to a newer release
`felis update` offers `sudo felis setup` for every planner-backed target and closed with a trailer calling setup idempotent. That is true for velocity -- install_velocity re-resolves the newest build of the pinned minor on each run -- and misleading for felis-api, which both --panel and --plugins resolve to. setup hands bootstrap the binary it is itself running and takes the bootstrap_from_tui arm, which skips the release lookup. The run rebuilds the image and rolls the deployment off that SAME binary: it reports success and leaves the version exactly where it was. An operator following this guidance to apply a felis-api update would watch it appear to work and then see the same version reported again. Only the bootstrap installer moves felis-api, and naming it is where this gets dangerous, so the warning ships with it. The installer is not an updater. Every run re-derives FELIS_ROOT_DOMAIN through detect_node_ip and defaults it to <node-ip>.nip.io; nothing reads the domain back out of the felis.toml an earlier run wrote. A bare re-run -- which is exactly what README documents, with no environment at all -- rewrites root-domain, panel-hostname and admin-hostname to nip.io names, while ensure_panel_tls_cert returns early on the certificate it already wrote and keeps serving the old hostnames. The console then fails to match its own certificate, and there is no re-domain flow to recover with. Persisted secrets are not at risk: load_or_make_secrets sources secrets.env before it generates anything. felis update stays report-only, so no command changed; only the claim about what the offered one accomplishes, and the conditions under which the alternative is safe to run. Tested four ways, because the scoping and the warning are both the point: --panel carries the caveat AND names FELIS_ROOT_DOMAIN, --velocity keeps the ordinary trailer without either, and --mc, which offers no command at all, gets neither. |

fix(setup): refuse --dev rather than silently installing the release channel
`felis setup --dev` promised "install the dev channel (main HEAD)" and installed release: the flag only exported FELIS_CHANNEL, a variable nothing in the tree reads. deploy/bootstrap.sh reads FELIS_VERSION_BOOTSTRAP. Renaming the variable would have been a worse bug than the dead one, because it would look wired. setup runs bootstrap with FELIS_BOOTSTRAP_FROM_TUI=1, and on that arm every reader of FELIS_VERSION_BOOTSTRAP is unreachable: the channel case and its validation live in resolve_install_ref, which the TUI path skips outright, and use_release_binary is only consulted by the elif that `if bootstrap_from_tui` already short-circuited. setup re-images the host from the felis binary it is itself running; there is no channel to pick. So the flag refuses, exits 2 and names FELIS_VERSION_BOOTSTRAP=dev on the installer, which is the mechanism that does work. Refusing beats defaulting: the operator asked for dev, and release is the one answer they did not want. The refusal precedes the root check, or an unprivileged operator gets told about sudo instead of about the channel. channelName had no other caller and goes with it. Nothing else referenced --dev -- no doc, no script, no test -- so this removes a promise the tree only ever made to itself. |

fix(bootstrap): wrap the downloaded binary in the same base CI ships
build_image_from_binary built on distroless/base-debian12 while the repo
Dockerfile's final stage uses distroless/static-debian12, so the image an
install runs did not match the image CI publishes.
Every binary that can reach HOST_BIN traces back to the Dockerfile's
CGO_ENABLED=0 build -- the downloaded CI asset, the binary the TUI is already
running, and the one build_image_from_source docker-cp's out of the image it
just built. None link glibc, so base-debian12 bought nothing and only widened
the runtime surface.
This mattered little while build_image_from_binary was the rare fallback.

feat(updater): authenticate GitHub polling and track the real release repo
felis-api's coord was the placeholder "felis/felis", which resolves against nothing on real GitHub. It is now MliroLirrorsIngenuity/Felis — the same slug deploy/bootstrap.sh clones from — so update reporting for the control plane itself is live rather than parked. That repo is private today, so the github source gained an optional token, read from FELIS_GITHUB_TOKEN: the variable bootstrap already needs, so an operator sets one value once. It comes from the environment and is never compiled in. A constant would be committed to the very repository it protects, ship inside every felis binary where strings(1) recovers it, reach every node the image is imported onto, and need a rebuild and a redeploy to rotate. Empty stays the correct posture for the other tracked components — k3s and cloudflared are public — and an empty token sends no Authorization header at all rather than an empty one. GitHub answers 404, not 401 or 403, for a private repo the caller cannot see, so "no token" and "no stable release published yet" arrive as the same status. On an unauthenticated 404 the error now names both causes and the variable that fixes the actionable one. With a token already set that hint would be wrong, so it is suppressed. Tests pin both halves: the Bearer header is sent only when the token is set, and the diagnostic names the variable only when it is not. doc.go's CAVEATS bullet still described the coord as a placeholder and the component as "dark at runtime". Both were true only until this change; it now records the real condition, which is that the component resolves like the others but needs a credential while the repo is private. |

feat(bootstrap): install the published release build instead of compiling on the host
deploy/bootstrap.sh now resolves the newest published GitHub release, downloads
the binary CI built for that tag, and builds a thin image around it. Compiling
on the target host becomes the fallback and the opt-in, not the default.
The panel is not a separate artifact. The Dockerfile copies panel/dist into
internal/panel/static before the go build, so the control plane — panel and
backend — ships as ONE file. The release channel therefore downloads exactly
one asset, felis-linux-<arch>, and needs no registry, no Go toolchain and no
checkout on the host.
The Minecraft game stack (limbo, lobby, the Velocity plugin) is still always
built locally. game_stack_source now keys on HAVE_PREBUILT_BINARY — the same
flag build_image uses — so on any prebuilt path it unpacks the tar embedded in
that binary instead of trusting a checkout an earlier install left behind.
Trusting the checkout would build the plugin from an old commit against a
freshly downloaded control plane: a silent version skew across the plugin/API
boundary.
Channels:
(default) newest published release, downloaded
FELIS_VERSION_BOOTSTRAP=dev clone main and compile
FELIS_REF=<ref> pins the tree, forces the source path
The download is best-effort. A tag whose assets are not uploaded yet, an
architecture with no published asset, or an asset that fails validation each
warn and fall back to compiling THE SAME TAG from source — never a different
commit.
The ref is resolved right after install_base, the first point curl exists and
well before docker and k3s, so a missing FELIS_GITHUB_TOKEN or an unpublished
release costs the operator seconds instead of a k3s install they then have to
unwind. It is skipped on exactly the paths that never consume the result: the
TUI, which rebuilds the binary it is already running, and FELIS_SKIP_FETCH,
which builds whatever is staged. Resolving anyway would set FELIS_VERSION to
the newest tag and stamp a staged tree as that release.
The asset is staged next to HOST_BIN rather than in TMPDIR. Validation EXECUTES
it, and /tmp is noexec on CIS-hardened images, where the exec dies 126, the
check reads it as a bad asset, and every such host silently falls back to the
full on-host compile this path exists to avoid. It also keeps a private-repo
artifact out of a world-readable 1777 directory.
git_auth, which supplies the token to git for a private-repo clone, passes an EMPTY
credential.helper before the inline one. credential.helper is multi-valued: a bare
`-c credential.helper=...` APPENDS to whatever the host has configured rather than
replacing it, and an empty value is git's documented list reset. Without it, on a host
with a persistent helper (Git for Windows ships `manager` at SYSTEM scope) two things
go wrong. Git runs `credential approve` automatically after a successful clone and
feeds every helper in the list, so a `store` helper writes the PAT to
~/.git-credentials in cleartext — the token outlives the install, in a file bootstrap
never created and never cleans up. And because the inline helper is LAST, a
pre-existing helper answers `fill` first, so a stale cached credential can win and the
clone authenticates as the wrong account — surfacing as exactly the 404-on-private-repo
the surrounding code works hard to explain. Reproduced both against a real clone, and
confirmed the reset closes both.
internal/panel parses the new stamp. The dev channel now emits "<tag>+g<sha>", which
matched neither describeSuffix ("-N-g<sha>") nor releaseTag, so a dev build fell through
to the default case and the version badge rendered the entire stamp as the release with
no commit. A devSuffix case handles it; the git-describe case stays for hand-rolled
`-ldflags "-X main.version=$(git describe)"` builds. Table test covers both forms plus
the release, dirty and unstamped cases.
CRD application no longer branches on the install path: it is always
`felis bootstrap-assets crd`. That output is byte-identical to deploy/crd/ —
bootstrap_asset.go embeds that very file — and needs no checkout, so one source
replaces a branch whose two arms had to be kept in agreement by hand.
Dockerfile gains a FELIS_VERSION build arg wired into -X main.version, declared
after `go mod download` so a version bump does not invalidate that layer. Both
build stages are pinned to $BUILDPLATFORM so a multi-platform buildx run never
emulates them: the panel's output is architecture-independent and the Go stage
cross-compiles via TARGETARCH. The final stage stays on the target platform and
is COPY-only, which BuildKit performs without QEMU.
.github/workflows/release.yml publishes on a vX.Y.Z tag: vet, tests, then one
buildx run producing both architectures through the repo Dockerfile. Not a bare
`go build` — internal/panel/static holds a tracked placeholder index.html so the
//go:embed compiles without node, which means a direct build succeeds and
quietly ships a release whose panel is that placeholder.
The stamp is asserted end to end, because it fails silently: an unstamped binary
reports "dev", which the updater refuses to compare, disabling update reporting
for every install built from that release. The arm64 artifact is checked by ELF
machine type rather than by running it — runners have binfmt registered, so
executing an amd64 binary misnamed arm64 would succeed.
Prerelease tags are flagged explicitly. The trigger glob is v*, gh does not read
semver out of a tag name, and an RC published as a full release becomes
/releases/latest — the single endpoint the default channel installs from and
`felis update` polls.
No SHA256SUMS. A checksum fetched over the same TLS session, with the same
credential, from the same host as the binary adds no trust root; signing is the
real answer and is a separate decision.
Not verified: the download -> validate -> image -> k3s path has never run on a
host against a real published release, because no tag exists yet. The shell
logic around it is verified out of tree; the network and exec behaviour is not.

fix(bootstrap): keep the install alive on a host with only felis-api
restart_existing_control_plane ended in an and-list per deployment:
[ "$had_api" = "1" ] && kube ... rollout restart deployment/felis-api
[ "$had_operator" = "1" ] && kube ... rollout restart deployment/felis-operator
As the LAST command of a function, an and-list whose test is false returns 1,
and that becomes the function's exit status. The call site is bare, so under
`set -Eeuo pipefail` the installer dies there — after the bundle has been
applied and before the rollout wait, leaving a half-finished upgrade and no
message naming the cause.
It fires on any host carrying one control-plane deployment but not the other:
felis-api present without felis-operator restarts the api, then exits 1 on the
second test. Both present, or neither, happened to work, which is why it
survived.
Rewritten as explicit `if` statements, which return 0 when the test is false.
Verified out of tree against all four had_api/had_operator combinations.

feat(files): add the server file editor
Give an owner a way to repair the one failure no other endpoint covers: a
server that will not boot because a single line of server.properties or a
plugin's YAML is wrong. Until now that needed a human with cluster access.
felis-api cannot touch a world in-process — the world PVC is ReadWriteOnce
and its lifecycle belongs to the operator's StatefulSet — so the work runs
as a one-shot Job, and the server must be stopped first because a running
one holds the volume. That is the same constraint that shapes restore and
backup, and the handlers enforce the stopped gate the same way.
What is different is that the caller wants the OUTPUT, not just the side
effect. The Job prints its result to stdout and felis-api reads it back
through the pods/log subresource, which needs no permission felis-api does
not already hold: jobs:create, pods:list, pods/log:get. No pods/exec, no
pods/portforward, not even pods:get. The price is latency — every operation
is a Pod schedule — which is why this is a repair tool and not a file
manager.
Containment is structural, not textual. Every filesystem access goes through
os.Root, the stdlib's escape-proof directory handle, which resolves each
component against the open root descriptor and refuses "..", absolute paths,
and symlinks leading outside. The string-prefix check used elsewhere is not
reused here: it validates a path as text and then opens it as a path, and a
world directory holds attacker-influenced content, so a symlink swapped in
between those two steps is a live threat rather than a theoretical one.
os.Root has no such window because the check and the open are one operation.
The Job's isolation is a strict subset of a restore Pod's: the weak
felis-restore SA with its token auto-mount disabled, exactly one volume (the
world PVC, mounted read-only for list and read so two of the three
operations cannot mutate anything), no Secret, no ConfigMap, no database
URL, non-root with an fsGroup matching the operator's so a written file is
readable by the server that later mounts it, and backoffLimit 0 so a failed
write is never silently retried as a second write.
Two limits on the surface are worth stating plainly, because the mount is
the server's whole working directory rather than a config subtree:
* A write accepts arbitrary bytes at any path, so an owner can place a
loadable plugin jar. This is deliberate — it is what a hosting panel's
file manager does, scoped to a server the caller already owns and
already drives through /command — but it is the one owner-tier route
that lands executable code in a backend pod, since images are
admin-only and modpack submissions need an admin verdict.
* config/paper-global.yml is refused on read. felis-lobby's entrypoint
writes FELIS_FORWARDING_SECRET into it on every boot, and that value is
identical on every backend, so reading it from a server you own would
hand you the handshake key for everyone else's. It is the only path in
the mount that is not the caller's own data, and therefore the only
denial. The comparison is on the cleaned path, or ./config/... would
walk straight through it.
Writing that file is still allowed: it leaks nothing, and the entrypoint
rewrites it whole on every boot regardless.
The write body's content field is a *[]byte rather than a []byte for the
reason permissionRequest.Value is a *bool — a plain slice makes absent,
null, and empty indistinguishable, so a body of {} would decode to nil and
truncate the target to zero bytes while answering 200, destroying the very
config the caller opened the editor to repair.

feat(cli): report component updates and make the router a data table
Add `felis update`, which reports which platform components have newer versions available, and route `felis version`, which shipped implemented but unreachable. That bug is why the subcommand router is now a map rather than a switch. cmdVersion existed with nothing dispatching to it and no usage line, so `felis version` fell through to "unknown command" and no test noticed — a switch offers no way to enumerate what it routes, so the usage text and the router could not be compared. As data, they can: a test now walks the Commands: block and the table in both directions, failing an entry added to one without the other. bootstrap-assets stays deliberately undocumented and is listed as such, which makes its absence a decision rather than an oversight. The host gatherer answers the two seams NewSysGatherer leaves nil, for the one caller that can satisfy them without a cluster client. felis-api is answered from the running binary's own build stamp rather than the Deployment's image tag: deploy/bootstrap.sh builds the image from the same checkout it installs /usr/local/bin/felis from and stamps both with one git describe, so it is the same artifact, and it is the identity `felis version` reports. Reading the Deployment answers a slightly different question — what is rolled out — and stays the right seam for the in-cluster path. Velocity is read from the jar's own META-INF/MANIFEST.MF Implementation-Version, which is what the proxy reports about itself at runtime, because bootstrap installs the jar under a fixed name with no version in it. The filename extractor remains only as a fallback for a hand-placed velocity-3.5.1.jar. An unstamped local build reports "dev" and is refused with an actionable message rather than being treated as 0.0.0, which would make every release upstream look like an upgrade. The panel and the plugin jars have no version of their own on purpose: they are embedded in or built alongside the felis binary, so the felis version is theirs. |

feat(images): mark platform-curated images and seed the lobby
The create-server form has no way to tell a user which of the whitelisted images is a sensible starting point. Add 'recommended' as a third image_whitelist.source alongside 'built' and 'external', and seed it with the one image that has earned it. The marker is presentation only. ImageAdmitted still turns solely on enabled, so a recommended row is admitted by exactly the rule that governs every other row and carries no extra privilege; a test pins both halves, because the failure modes are silent and opposite — make admission source-aware and the curated images vanish from the form, or let curation bypass the disable switch and an admin who pulled an image finds it still creatable. Only one image is seeded, and the restraint is the point. Velocity runs proxy-wide modern forwarding, so a backend that cannot verify the signed handshake rejects every login the proxy sends it. The operator injects FELIS_FORWARDING_SECRET into every backend but cannot make an image consume it. An arbitrary public Minecraft image therefore passes admission, builds, schedules, reports Ready — and then refuses every join, with nothing in the server's status explaining why. Exactly two images read that variable, deploy/limbo and deploy/lobby; limbo is the login gate and is nonsense as a base for a user's server, which leaves lobby. The list grows when Felis ships another forwarding-aware image, not before. AdmitBuiltImage now preserves a 'recommended' source through its ON CONFLICT path. Rebuilding a curated tag is the expected way to patch it, and that rebuild arrives through this exact path, so a blind SET source = 'built' would demote the curation on the first rebuild with nothing in the request saying so. AddExternalImage deliberately does not preserve it: an admin POSTing the ref is an explicit, named re-admission, and the 201 body reports the Image it constructed without re-reading the row, so a sticky source there would report a value the database does not hold. The migration is idempotent via ON CONFLICT DO NOTHING, so an admin who disabled or re-pointed the row does not have that decision undone on the next apply. |

feat(api): let in-game staff manage any server without claiming it
The web face has always granted staff the run of the fleet (isOwnerOrAdmin passes an admin for stop/command/console/access on any node), but the internal face explicitly had "no admin tier": a linked administrator in game could only wake servers they owned or that autostartPolicy permitted. The only way to manage another player's (or an unclaimed) server from inside the game was to claim it — seizing ownership and burning the admin's own quota. Give authorizeWakeByUUID the admin tier on the same trust anchor the op-login approve already uses: verified online-mode UUID -> account link -> stored role. A linked staff member now wakes ANY node under any policy (so `/felis go` works fleet-wide without claiming); the owner bypass and the policy gates are unchanged, and an unlinked UUID still fails safe. Centralize the staff-role rule while at it: staffRole(role) in auth.go (admin, plus owner as its superset) now backs Principal.IsAdmin, the session ViaAdminAccess grading, the op-login approve gate and the new wake tier. That also fixes a real hole in the approve gate, which required role=admin exactly: an Owner manually promoted to role='owner' per migration 0011's upgrade note would have been refused by their own in-game approval door. The lobby menu still renders "Claim & Start" on ownerless tiles — claiming becomes optional for staff rather than the only entry — so the velocity plugin needs no change. |

feat(auth)!: go fully passwordless and fix cross-check review findings
Remove password authentication everywhere; the only session doors are passkey (WebAuthn), email OTP, in-game bind codes, QR scan-login, and op-login vouching. Remediates the 33-finding cross-check review across backend, CLI, panel, plugins, and docs. Backend/CLI: - Drop password routes and fields from account/user/onboard/auth handlers; align tests (new account subtests, naming reserves "console", op-login/onboard/qr-login test updates). - Add migrations 0016_op_login.sql and 0017_drop_password.sql. - Thread panel/admin hostnames from hostcfg through api.go, setup_panel.go, tui_root.go and tui_preflight.go instead of hardcoding; bootstrap.sh writes panel-hostname/admin-hostname into felis.toml. - Reword breakglass and TUI copy for passwordless flows. Panel: - Delete the ChangePassword page and all password UI; align login/auth/api/types with the passwordless contract; add the migration and op-login approval flows. - i18n: convert ImageBuildPage durations/status badges and ServerLuckPerms strings to translation keys; drop 72 orphan keys per locale; unify the title as "Felis - Console". Plugins (all six rebuilt): - Velocity waiting router returns 503 at_capacity during wake; MOTD/control-channel copy and config comments. - Paper zh menu title; Limbo bind-code TTL 600s with panel_url preference; unified /link lines in fabric/forge/neoforge; shared link-client javadoc contract fixes. Docs: openapi.yaml, sequence-diagrams.md, deploy/limbo/README.md and plugins/README.md aligned with the implementation. BREAKING CHANGE: migration 0017 irreversibly drops users.password_hash and users.must_change_password; password login cannot be restored after migrating. |

A single HTTP 502 from fill.papermc.io aborted the entire bootstrap. Build resolution used a one-shot curl, so one gateway blip from an upstream that flaps was indistinguishable from a permanent failure, and the run died before Docker, k3s or any game server was provisioned. Pass --retry 5 --retry-delay 2 to the build-resolution fetches. 502/503/504 are already in curl's built-in transient set, so the tool had solved this; the flags were simply never passed. papermc_latest_jar is shared by the Paper and the Velocity resolve, so hardening it once covers both callers. The LOOHP/Limbo CI metadata fetch feeds the same step and gets the same treatment. Deliberately no --retry-connrefused. It only adds ECONNREFUSED to a set that already covers this incident, and it needs curl 7.52.0 while the yum (el7) path the script supports ships 7.29.0, where an unrecognised long option is a parse error rather than a warning: # centos:7, curl 7.29.0 $ curl -fsSL --retry 5 --retry-delay 2 --retry-connrefused https://example.com curl: option --retry-connrefused: is unknown Under set -Eeuo pipefail that exits 2 and trips the || die, so both hardened fetches would hard-fail on a host where they used to work, each naming a cause that is not the real one. A comment above papermc_latest_jar records this so the flag does not come back. The failure message was actively misleading. "no Paper build for Minecraft 26.2 (the login gate speaks only that protocol)" reads as "that Minecraft version is unsupported", sending the reader after a version-pinning problem that does not exist: Paper 26.2 build 60 resolved fine minutes later. Say what is actually known instead, that the build likely exists and Fill is flapping. Verified against a local always-502 server: curl now issues 6 requests (1 initial + 5 retries) over 10.1s before giving up, where it previously issued 1 and died. Verified on centos:7 that this flag set is accepted, and against the live Fill v3 API that the resolve still returns a jar URL. Known and deliberately unchanged: no fetch sets --max-time, so an upstream that accepts a connection and never answers still blocks forever. --retry does not cover that, as it fires only once a request completes with a failure. The remaining single-shot downloads (cloudflared, the Docker GPG key and repo list, k3s, the Temurin JRE, the Velocity jar, the Go toolchain) keep their existing no-retry shape rather than widen this diff on a script that is about to provision a live host. |

fix(setup): record email unverified so onboarding works without SMTP
At bootstrap there is no SMTP, so the old /setup flow was unreachable: it requested an emailed OTP that could never arrive. Setup now records the Owner's email address unverified (no OTP round-trip) and requires a passkey, deferring SMTP configuration to a later Settings page. Setup completes on email-recorded + passkey-enrolled, and the lockdown lifts on the passkey, not on email_verified: a passkey is the Owner's only pre-SMTP login credential (email-OTP login refuses admin accounts). The record-email endpoint (POST /account/email) now clears email_verified in the same write. Only VerifyEmailOTP, which proves control of the address, may set that flag; recording a fresh unproven address must never leave a stale email_verified=true asserting a proof the user never gave. The change strictly tightens the invariant, so no existing reader breaks. Remove the dead ErrEmailTaken path and its documented 409: no migration puts a unique index on users.email and the codebase does not enforce email uniqueness, so the unique-violation branch was unreachable and the 409 an impossible response. The /setup route (Setup.tsx, setEmail helper, setup i18n copy) is rewritten to match: record-email, mandatory passkey, no skip-for-now. The SMTP settings page and post-setup configure-SMTP nudge are deferred. |

fix(cfsetup): regenerate missing tunnel credentials on re-bootstrap
cloudflared writes the tunnel credentials JSON only at `tunnel create`. An idempotent re-run against a tunnel that already exists — or a reset + re-bootstrap where the old box's ~/.cloudflared was wiped but the Cloudflare-side tunnel survived — finds no local credentials file, and the connector crash-loops with "Tunnel credentials file doesn't exist". A tunnel that never comes up leaves op.console unreachable, so the one-time setup link minted just before it ages out (30-min TTL) unredeemed. CreateTunnel now resolves the tunnel id on both paths (fresh create and already-exists) and routes through ensureCredentials, which re-fetches the token with `cloudflared tunnel token --cred-file` (authenticating via cert.pem, preserving the same id / DNS / Access) when the file is absent. The secret is written to the file, not stdout, and the file is chmod 0600 so it is not left world-readable next to cert.pem. The self-heal is unconditional on re-bootstrap: Setup gates on Pre.check() (cert.pem present) before CreateTunnel, so the token re-fetch always has its cert.pem authority. |

feat(setup): add the op.console owner onboarding wizard
The /setup route redeems the one-time token from `felis setup`, then walks the Owner through email-OTP verification and passkey enrollment before handing off to the console. It sits outside RequireAuth — the visitor arrives without a session and the redeem is what mints one — and is reload-safe: a spent token resumes from the surviving session via /auth/setup/status. Adds the Setup page and its /setup route, the setup API client methods (redeem/status), and the en-US/zh-CN onboarding strings. |
