Manage Yggdrasil providers from the panel using durable platform settings, protected identity namespaces and atomic revisions. Apply changes to subsequent logins and profile lookups without restarting. Return operator-host logouts to the login method selection page.
Configure connection and storage before creating or resuming the one-time Owner login. Remove Minecraft prerequisites from setup and preserve established login credentials.
Let staff preview and confirm roles from configured authentication sources using the existing account-link storage and game UUID mapping. Retain in-game code proof for players, add client-version and lobby guidance, and support NodePort passkey origins.
Two defects live-drilled in the break-glass staff provisioning:
- An Owner reset that typed any username other than the occupied seat took
UpsertOwner's insert arm and silently minted a SECOND owner row, leaving the
existing seat — possibly the compromised account the reset was meant to
replace — live; every owner row is undeletable through the panel, so the tier
could never converge back to one. provisionOwner now refuses with
ownerSeatTakenError naming the seat (recoverable: the TUI routes back to the
form); bootstrap still mints, and the seat's own username still resets in
place. PGRepo gains OwnerUsername for the guard.
- InsertOperator returned the raw driver error on a taken username while the
console keys its rename prompt off api.ErrConflict — the "choose another
name" leg died with SQLSTATE 23505 against real Postgres (the fake encoded
the contract; PGRepo had drifted). Map the unique violation to ErrConflict
and pin it in pgint.
Live (auditfix37): fresh username refused naming the seat; seat reset kept the
id/email with still exactly one owner; taken operator name returned to the form
with the retry note, and the retyped name succeeded (drill rows cleaned).
UserByMCUUID now resolves only live accounts: claim, menu, wake
authorization, op-login vouch and the QR link-status poll treat a
disabled or soft-deleted link holder exactly like an unlinked UUID
instead of a retired identity. VerifyLinkCode lets a soft-deleted
link be taken over by a fresh in-game code (the deleted account is
gone, e.g. a migrated source), while a disabled holder still 409s so
the lockout is not bypassable; failed attempts still do not consume
the code. Fake repo and pgint coverage pin both branches.
Two defects in the §9.3 quota path, both invisible to the hermetic suite:
- Audit #4's TOCTOU was real and documented: QuotaCheck and ClaimServer were
separate statements, so two concurrent claims by one user for two different
ownerless servers both read count < max_servers and both won. The gate now
lives inside ClaimServer, in the SAME transaction as the ownership write,
under pg_advisory_xact_lock(hashtext(user_id)) — the aggregate read, the
four-dimension re-check (shared with QuotaCheck via one helper so the two
cannot drift), and the UPDATE are one serialized decision. The loser gets
ErrQuotaExceeded, which both claim handlers map to the same 403 the
sequential path gives; the server row is additionally taken FOR UPDATE so
same-server races still resolve to exactly one winner.
- The server PATCH path called UpdateServerResources(..., 0) for storage even
though a resources patch cannot change storage. The cached columns are the
ONLY input to the quota aggregate, so every resource patch silently dropped
that server's storage contribution from its owner's cap. The handler now
reads the current spec and passes storage through.
Red-then-green: the new pgint test drives two real concurrent claims against
max_servers=1 (before: both win; now: exactly one win + one gated 403, and the
DB shows one owned row); the hermetic suite pins the 403 mapping and the
storage-preserving cache write.
Found live while verifying the admin email-edit fix: the Owner account could
not load /api/v1/users at all. Root cause: migration 0011 adds the 'owner'
role and gates every user-administration route on it, but NOTHING ever wrote
it. break-glass (UpsertOwner), the setup MC-bind (CompleteOwnerSetup), and the
re-provision path all forced 'admin', so in a fresh install the entire
owner tier — list/create/edit/disable/delete users, quotas, sessions — was
unreachable. The role was a dead letter in the other direction too: staff
predicates that predate the role did not know it.
- UpsertOwner and CompleteOwnerSetup now write role='owner'; the username-
conflict arm re-asserts it, which is also the documented pre-0011 promotion
path ("re-provision via break-glass"). InsertOperator stays plain 'admin'.
- Staff doors learn the role: op-login start/finish admit the Owner; the
player email door refuses it like any staff account; the in-game approver
check already used staffRole.
- Reclaim protection: IsProtectedAdminLink (and the break-glass bootstrap
switch AdminExists) count admin OR owner — the Owner must never be displaced
by a Mojang-priority reclaim.
- Panel guards make migration 0011's claim true now that owner rows exist: an
owner can never be demoted, deleted, or disabled through the API (only the
local break-glass console resets the identity); username/email edits still
work.
Tests: pgint pins both provisioning paths, the protected-link predicate and
the reset/promote semantics; hermetic suites cover the owner-admitting staff
door, the owner-refusing player door, the three panel guards, and break-glass
attribution.
UpdateUser wrote a new address but kept email_verified, so patching a verified
account asserted a proof of an address nobody had proven — and the
pre-session login mails and resolves on exactly that flag, so a typo'd edit
could hand the account's sign-in codes to the wrong mailbox.
Changing the address now clears the flag in the same write; a no-op patch that
passes the same value keeps it. The fake mirrors the semantics, and the pgint
suite pins both halves (same value keeps proof, new value drops it).
The design has claimed since migration 0010 that at most one account can hold
a PROVEN email address, with ErrEmailTaken as the 409 a second verifier sees.
Neither half ever shipped: no migration created users_verified_email_unique,
and VerifyEmailOTP had no guard at all — the sentinel was defined but never
returned, so two accounts could both verify one address. The damage is not
cosmetic: the pre-session login resolves accounts BY verified email, so the
duplicate decided which identity a mailed sign-in code belonged to.
- Migration 0020 creates the partial unique index (lower(email) WHERE
email_verified) the comments have been citing — the database-level backstop.
- VerifyEmailOTP now refuses the take-over with ErrEmailTaken BEFORE consuming
the code (the address, not the code, is the problem), charges no attempt,
and maps a lost cross-user race (unique violation) to the same answer.
- The verify handler answers 409 email_taken instead of a generic 500.
Covered by the pgint suite (sequential double-verify refused with the code
still live, a direct duplicate write still loses to the index, the refused
account can still prove its own address) and a hermetic 409 case.
6-way concurrent redeem of one code 500'd on users_username_key (each request
generated a fresh user id but the same uuid-derived username), plus the rarer
two-codes-one-uuid race. Same drift family as VerifyLinkCode, which already
locks its code row and handles the conflict.
- SELECT ... FOR UPDATE the code row: same-code racers serialise; losers exit
as ErrLinkCodeInvalid (400 invalid_code), no user row is attempted.
- INSERT users ... ON CONFLICT (username) DO NOTHING + re-read by username:
cross-code racers converge on the winner's row (role checked, staff still
refused) instead of a unique-violation 500.
- account_links ON CONFLICT (mc_uuid) DO NOTHING for the same race.
Verified live: same-code x6 = 1x200 + 5x400; two-codes x2 = 2x200 same user;
db clean; zero unmapped errors.
The interface doc promised 'each joined to its staff username', the fake and
the pending handler both project username and created_at, but the PG query
selected neither — live internal /op-login/pending returned username:"" and
created_at:0001-01-01. Same drift class as ConsumeLoginEmailOTP: fake-based
tests can't see PG-only regressions.
The PG implementation was a single UPDATE ... WHERE code_hash that returned
ErrNotFound on zero rows: every wrong, expired, replayed or superseded code on
the pre-session email-login door (and the op-login finish / migration confirm
doors) fell through to writeError's unmapped-error 500, and attempts were never
charged so otpMaxAttempts/ErrOTPLocked could not trigger. The fake repo and the
Repo interface ("SAME code lifecycle as VerifyEmailOTP") already documented the
intended contract; only the PG side had drifted.
Mirror VerifyEmailOTP's transaction without its users write: SELECT ... FOR
UPDATE the newest live row, expiry + attempt cap before the hash compare,
mismatch charges one attempt and returns ErrOTPInvalid without consuming,
match consumes and commits. Verified live on the VM: 5 wrong guesses return
400 and stop at attempts=5 (correct code then also refused, unconsumed);
fresh code redeems; replay returns 400.
Nine files had drifted from gofmt and nothing checked; nine staticcheck
findings were live (three dead symbols, capitalization, a redundant
Sprintf, two literal-to-conversion sites, a nil test context). Fix all
of them and make CI fail on unformatted Go so this cannot re-drift.
Felis never actually sent mail: OTP codes for onboarding, email login and
op-login were only written to the felis-api log behind a "demo has no SMTP"
limitation, and the Settings/SMTP flow those comments promised was never
built. Combined with the bootstrap Owner's address being recorded unverified
(87279a1), op-login start always took the anti-enumeration neutral branch and
minted a fake request_id, so the in-game approve inevitably answered "No
pending operator sign-in with that code".
Give the codes a real delivery path, configured in felis.toml rather than a
web settings page so config keeps a single source of truth:
- config: new [smtp] table (host, port defaulting to 587, from, username,
password_ref). Validation requires a plausible from address and a sane
port; the password itself never enters the config file.
- internal/mail (new): stdlib net/smtp mailer implementing the api.OTPMailer
seam. Port 465 dials implicit TLS, other ports upgrade via STARTTLS when
advertised; AUTH only when a username is configured (PlainAuth itself
refuses plaintext, so the password cannot leak to a TLS-less relay).
Ping() proves reachability and credentials without sending mail. The
message shape (CRLF, Q-encoded bilingual subject) is pinned by test.
- platform: felis-smtp Secret constants and an optional FELIS_SMTP_PASSWORD
env var on the felis-api Deployment, mirroring felis-uploads-s3.
- cmd/felis api: construct the real mailer when [smtp] is configured; keep
the log fallback otherwise and say so at startup. Warn when a username is
set but the credentials env is empty.
- setup TUI: "e" on the summary/status screen opens the email form (host,
port, from, optional auth). Apply order: Ping preflight, [smtp] into both
host and pod config files, felis-smtp Secret piped to kubectl via stdin,
config Secret, felis-api rollout. A failed preflight leaves the install
untouched. SMTP is deliberately not a wizard rail step: first-run stays
mail-less by design, and the passkey minted at onboarding is the pre-SMTP
owner credential.
Also make PGRepo.UserByEmail match case-insensitively (lower(email) =
lower($1)), honoring the interface contract and the users_verified_email_
unique partial index; the fake repo already matched with EqualFold.
Existing installs need the felis-api Deployment manifest re-applied (e.g. a
bootstrap re-run) before the new env var exists; a rollout restart alone
cannot add it.
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.
