Nothing ever removed a submission: users could not retract a pending row, no
route deleted blobs or rows, and the reaper never touches uploads — so every
upload accumulated on the 5 GiB PVC forever and the only cleanup was SQL or
kubectl against the store.
- Blobs.Delete on both transports (local: RemoveAll of the id-namespaced dir,
id re-validated at the boundary; S3: idempotent object DELETE).
- Store: DeleteSubmission (admin, any status) and DeletePendingSubmission
(owner+pending CAS — a reviewed row can never be withdrawn out from under
its build).
- Manager.Delete / Manager.Withdraw delete the ROW first (under the CAS for
withdraw) and the blob after, so a live row can never point at a reaped
blob; a cleanup failure names the orphan explicitly instead of failing mute.
- API: DELETE /me/submissions/{id} (withdraw, app tier) and
DELETE /api/v1/submissions/{id} (admin) both return the row as it was;
audit events submission.withdraw / submission.delete; openapi documents both
paths; admin route pinned in the admin-only table.
- Panel: two-step withdraw on a pending row (frees the pending slot and the
storage budget); two-step delete on every admin row; zh/en copy; wire tests.
Unit: submit (withdraw happy path / wrong owner / reviewed row / no transport /
blob-cleanup failure), local+S3 delete idempotence, api handlers (200/404/409/
503 + route tier); pgint: withdraw CAS + admin delete exactly-once.
go vet/go test/gofmt clean; panel vitest 120 + typecheck green.
A logged-in user could file submissions without bound and stream a 1 GiB
context per submission. The only limits were the single-blob size cap and the
5 GiB uploads PVC (platform/workloads.go); nothing counted a user's rows or
bytes, so one account could fill the volume and every other user's upload
would start failing.
- Create: per-user pending_review cap (default 5) — the review queue cannot
be parked full of one account's rows. Check-then-insert, documented soft.
- UploadContext: per-user stored-context budget (default 2 GiB) charged
against the blob store's REAL sizes (new Blobs.Size on local/S3 stores), so
the sum cannot drift from the volume; the write is capped at the remaining
budget, so the excess is refused before it is persisted, and a re-upload is
charged only for its new bytes.
- API: per-user create/upload throttles (30s/15s, cmd/felis-wired) on a
dedicated cooldown keyspace, reserve→release so a failed attempt never
burns the window and a burst collapses to one winner; ErrQuotaExceeded →
403 submission_quota_exceeded (distinct from the 400 an oversize blob
gets), 429 submission_cooldown for the throttles.
- Panel: zh/en copy for both codes; openapi documents 403/429 on the two
user routes; pgint covers the pending-queue count.
Unit tests: submit package (cap, budget boundary/exact-fit/replacement,
oversize-vs-quota split) and api handlers (quota 403 both paths, throttle
429 + recovery + failure-release). go vet/go test/gofmt clean; panel
vitest 118 + typecheck green.
login/lobby carry reserved names, so every per-server route rejects them —
yet the cockpit offered claim/stop/wake and a console link on their rows,
each answering 400 bad_name. The fleet view now marks them (system:true,
shared naming.IsSystemServer) and the panel renders a plain label instead
of dead actions.
/me/submissions (and the admin queue) now attach build_status/build_error by
a read-only Builder.Get — until now a failed build was visible only on the
admin-tier /images/build routes, so the person who submitted the modpack
never learned the build died. A missing build row renders as "no outcome";
any other lookup failure surfaces instead of being swallowed. The panel's
My Submissions page renders the outcome in the expanded row, localised.
A submitted modpack was durable but unreadable: the uploads PVC cannot cross
namespaces (felis-api mounts it; Kaniko runs in felis-build) and the s3 lane
handed the sandboxed build Pod no credentials, so NO user build could ever
consume its context. The transport is now the API itself:
- submit: derived context refs become the internal-face URL
/api/v1/internal/submissions/{id}/context (service-token gated), and Blobs
gains Open (local + s3) with an ErrBlobNotFound sentinel for the route's 404.
- api: serves that route on the internal face only (openapi.yaml updated; the
route-coverage test enforces it).
- build: an http(s) context renders a context-fetch initContainer (the felis
image's new fetch-context entrypoint) that streams the blob with the
namespace-local service-token Secret — never mounted into Kaniko — and
extracts it under a zip-slip guard into a size-limited emptyDir that Kaniko
reads read-only as --context=/context.
- platform/install: the api Deployment carries its own internal base URL; the
build namespace gets the token Secret through the existing replica mechanism
(bootstrap.sh + felis setup); the build egress lock opens exactly the control
namespace on the internal port.
- cmd/felis: fetch-context entrypoint (registered, documented, unit-tested for
escapes/symlinks/non-gzip).
Tests cover rendering, hardening, the s3/local Open paths, and the route's
404/503 mapping. Verified next on the real single-node cluster with Kaniko.
- [registry] gains kaniko_image / trivy_image / build_cpu_limit /
build_mem_limit overrides; empty keeps the compiled-in defaults. An
air-gapped or mirrored install has no route to gcr.io/aquasec (the
build egress policy allows only DNS + registry + package mirrors), so
builds previously could not even start their executors.
- deferred-seams: the uploads-context entry now records WHY a mount is
impossible (PVCs cannot cross namespaces) and that the s3 lane also
lacks credentials in the build Pod — options captured for the real fix.
- troubleshooting 8e (executor ImagePullBackOff + the overrides),
13b rewritten (verified eviction refusal, 5m pressure-transition,
image-GC recovery), 15 (upgrade/rollback runbook for Recreate).
- Backup semantics decided and documented: a backup is the whole /data
volume (worlds + config + plugins + cache) and a restore rolls all of
it back — OpenAPI/README wording updated to match (same-tag images are
still watched for regressions by the openapi parity gate).
Backup and restore only enqueue a cluster Job; a later failure left its
only trace in that Job object, invisible without kubectl. Add
GET /api/v1/servers/{name}/jobs (owner-or-admin) projecting the newest
20 managed Jobs (felis-backup / felis-restore) as
running|succeeded|failed with message and timestamps. Nil reader -> 503
jobs_unavailable, mirroring the backup/restore feature gates. RBAC gains
jobs:list; OpenAPI parity updated.
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.
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 ecbeb20: a
generated file holding a hand-set value with no carry-forward.
Tests cover the case a MAIL FROM probe cannot see: a fake relay that answers
250 to MAIL FROM and 550 at end-of-DATA must fail both Ping and SendOTP, and
the 502 must carry a distinct machine code without leaking the relay's text.
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.
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.
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.
Adds a break-glass console operation that snapshots a stopped world by
calling the felis-api internal face while the API is alive, rather than
rendering the backup Job locally: the Job needs felis-api deployment
coordinates the console does not hold.
The peer resolves the felis-api-internal ClusterIP Service + service
token from the control namespace, POSTs the internal backup endpoint
with the operator os_user for audit attribution, and maps 409/503/404
to friendly outcome cards. Core decision logic lives in backupnow.go
(unit-tested against a fake client + httptest); tui_backupnow.go is the
untested bubbletea glue mirroring tui_halt.go.
Add POST /api/v1/internal/servers/{name}/backup so the on-node break-glass
console can snapshot a stopped world while felis-api is alive. It goes through
the API (not direct-to-CRD like halt) because rendering the backup Job needs
deployment coordinates (FELIS_IMAGE, FELIS_BACKUP_PVC) only felis-api holds.
Service-token auth (no Principal); the middleware IS the authorization, since
the operator already has root on the node. Refactor the RWO stopped-gate,
optional-Backuper 503, async hand-off and audit+202 into a shared enqueueBackup
tail so the external (owner/admin) and internal (break-glass) faces cannot
diverge on the security-critical stopped-gate. The internal audit is attributed
to break-glass/internal so a console-initiated backup is distinguishable from an
owner self-service one.
Add POST /api/v1/servers/{name}/backup: an owner or admin snapshots a
stopped server's world into the archive store on demand, recorded as a
first-class world_backups row (reason `manual`) — restorable by the
existing restore path and expired by the reaper's retention pass, so it
never leaks as an orphan archive. This is the break-glass "Sync" op,
resolved as immediate/on-demand backup.
felis-api cannot archive in-process (the world PVC is RWO, held by the
operator StatefulSet), so the work hands off to a one-shot Kubernetes Job
(new internal/backupjob) that mounts the world PVC read-only and the
backup PVC read-write, plus the felis config Secret so it self-records
its row atomically like the reaper. The Pod mirrors restore's weak-SA
isolation (SA token un-mounted, non-root, read-only rootfs, drop ALL);
the one reviewed departure is that config-Secret mount, frozen by
jobspec_test.go. Handler answers 202 backing_up; gated on the server
being Stopped (RWO world PVC), owner-or-admin, and FELIS_IMAGE +
FELIS_BACKUP_PVC being wired (else 503 backup_unavailable).
Each request mints a unique Job name (backup-<server>-<rand>) so a repeat
on-demand backup produces a fresh archive rather than colliding with a
just-finished Job still inside its TTL window and silently no-op'ing the
retry.
Old account runs /felis migrate in-game to open a migration, proves control via a
fresh web step-up (passkey forced when enrolled, else email-OTP), names the target
and mints a one-time code. The target redeems it while authenticated AS that target:
in one transaction the source's owned servers re-point to the target and the source
is retired (sessions revoked, disabled, soft-deleted), which also spends the code so
it cannot be replayed. Only server ownership moves; the mc_uuid link and web
credentials stay with the source, so migrate is not a credential-theft primitive.
- 0015 migration: account_migrations state machine (initiated -> confirmed ->
code_issued -> redeemed), one live migration per source
- Repo/PGRepo: Start/ForSource/Confirm/IssueCode/Redeem
- 8 routes (1 internal /felis side, 7 web) with openapi parity
- passkey step-up runs the same clone-signal (sign-count) check as the login door
- code bound to the named target at issue and at redeem
Quota is grandfathered at redeem: no per-target quota re-check when servers move.
A from-zero login door: the browser calls navigator.credentials.get() with an
empty allowCredentials, the authenticator returns an assertion carrying the
resident credential's userHandle, and the server resolves the account from that
handle alone — nothing is typed or client-named.
Routes (both Public):
POST /api/v1/auth/passkey/login/discoverable/begin
POST /api/v1/auth/passkey/login/discoverable/finish
Begin stashes the ceremony SessionData server-side keyed by an opaque login_id
under a global cap; finish consumes it single-use, hands the
authenticator-revealed userHandle to a UserByID resolver, and mints a session
only for the account the assertion actually verified to. Every finish rejection
— no live challenge, expired, bad assertion, unresolvable handle — collapses to
one passkey_login_invalid envelope, so finish is never an existence/state
oracle. SignCount is surfaced but not yet consumed, exactly as the
username-first door, so the from-zero path offers no clone-detection bypass.
The discoverable VERIFY path is Oracle-verified end to end against a virtual
authenticator (internal/passkey): it resolves the account from the signed
userHandle, fails closed when the handle names no account, and rejects an
assertion signed by a credential not bound to the resolved user — the
impersonation guard unique to usernameless login. Enrollment now requests a
resident key (authenticatorSelection.residentKey=preferred), the only
server-side half a unit test can pin.
Whether an authenticator actually stores a resident key is a device property no
test can reach, so this door is INERT for a credential until its owner enrolls a
NEW passkey against these options; "preferred" (not "required") preserves the
no-lockout fallback to username-first + email-OTP.
The passwordless migration left ResetMailer (SendPasswordReset) and its API field with zero callers and no wiring; the web console authenticates via email-OTP and passkey only. Remove both, plus the now-orphaned context import that the interface was the last user of in handlers_users.go.
Reconcile the DeleteAllPasskeyCredentialsForUser docs in repo.go and pgrepo.go: they claimed there was no production caller, but 2f22027 wired the owner-tier DELETE /users/{id}/passkeys. Both now note that a complete authenticator remediation pairs the unbind with a session revoke (unbinding alone leaves the live hijacked session; revoking alone leaves a re-enrollable credential), and the OpenAPI operation carries the same guidance in a new description. Reword the stale local-password test-fake header, since the passwordless fakes carry no must_change_password field.
No behavior change. gofmt, build, and the full test tree are green; OpenAPI parity and passkey-unbind tests pass; a grep confirms ResetMailer/SendPasswordReset are gone from the Go tree.
Add DELETE /api/v1/users/{id}/passkeys (owner-only) to unbind every passkey a
target account holds — the authenticator remediation that stops a passkey planted
or retained via a transiently-hijacked session from surviving as a standing login
foothold. It wires the previously-uncalled DeleteAllPasskeyCredentialsForUser and
is deliberately not a lockout: the account re-enters via the email-OTP door
(players) or op-login's in-game approval (staff), then re-enrolls. Documented in
the OpenAPI, so the served/documented parity gate covers it.
Remove RevokeUserSessionsExcept: a change-password-era orphan with no callers
since the passwordless migration. Its keep-one ("log out my other devices")
semantics is inherently self-service, and no such slice is on the roadmap; the
admin remediation path already uses RevokeAllUserSessions.
Replace console password auth with a passwordless surface — the pre-session
login doors plus an identifier-first discovery endpoint — and remove the
password paths.
- Login doors (Public, pre-session): email-OTP, passkey assertion, op.console
login with in-game approval, and setup-token redeem.
- /api/v1/auth/options: identifier-first discovery reporting which console
methods an email can use. The single sanctioned existence oracle; methods
are computed with no role branch, so staff and player accounts in the same
credential state return byte-identical bodies (staffness invisible by
construction).
- Remove password auth: drop StaffUser.PasswordHash and the /auth/login,
/auth/change-password and /users/{id}/reset-password endpoints (and test).
- Data layer: UserByEmail, verified-email uniqueness, setup-token store
(migration 0012).
- Reconcile docs/openapi.yaml with the served surface; the method/path/face/
tier parity gate (TestOpenAPIMatchesServedRoutes) passes.
- felis TUI: in-game MC bind, owner/break-glass OP provisioning, version.
- Velocity /felis command suite.
Consolidates the accumulated backend migration work; the frontend (panel/)
is left untouched. Full Go tree green on WSL (go build ./... && go test ./...).
Two admin-tier routes read and set a single platform-wide maintenance
window for the auto-update subsystem (decision core internal/updates):
GET /api/v1/updates/window
PUT /api/v1/updates/window
The window is stored as JSON {"start","end"} (RFC3339, or null when
unset) under the platform_settings key "update_window", reusing the
existing GetSetting/SetSetting KV seam -- no new Repo method, no
migration. Pointer times keep "unset" (null) distinct from a real
instant on both decode and encode; a never-set and an explicitly
cleared window both read back as {null,null}.
Validation mirrors the core's fail-closed Window: a window is either
fully set (both ends, end strictly after start) or fully cleared (both
null). A half-set, inverted, or empty-interval body is 400 and is never
persisted. Reads treat only a missing key as unset (ErrNotFound -> 200
nulls); any other store error 500s rather than fail open.
This is API + PERSISTENCE ONLY. Nothing consumes the stored window yet
-- the runner, the ReleaseSource/Notifier/Applier executors, and the
scheduler CronJob remain INTEGRATION-ONLY. Setting a window changes no
behavior until those land; it is the durable input they will read.
Nothing here force-updates ("不要强制自动更新").
Adds POST /api/v1/auth/bind, the one public pre-account entrypoint of the
player console (console.<root_domain>). An account-less player redeems the
one-time Bind Code minted in the in-game Login Lobby; in a single step the
platform creates a role=user player, links it to the verified in-game UUID,
and mints a host-only felis_session. Login is thus not forced at the edge
while operations stay app-authenticated.
The operator console (op.console.<root_domain>) is unaffected and stays
behind Zero Trust: a code whose UUID resolves to a staff (role=admin)
account is refused with 403 (ErrPlayerBindForbidden) without consuming the
code, so the public door provably never yields an admin principal — the
session it mints carries ViaAdminAccess=false and is host-only to console,
never sent to op.console.
Repo layer: new RedeemPlayerBindCode on the Repo interface, implemented on
PGRepo (single tx: resolve code, create-or-fetch the player, consume) and
the test fake. The returning-player branch is idempotent and is a deliberate
standing "log in via the game" door, not just first-time onboarding.
Honest labeling:
- ORACLE-VERIFIED (Go): account/session logic — role=user, refuse-staff,
idempotent create-or-fetch, single-use code, and the op.console redline
(player session rejected on admin routes). Covered by handlers_onboard_test
and the OpenAPI parity gate.
- INTEGRATION-dependent: the endpoint's security rests on the Bind Code having
been minted against an online-mode-Yggdrasil-authenticated UUID, a
precondition that lives in velocity/Java and is not verifiable from this
repo (CODE-ONLY). The Go layer proves the logic, not that identity guarantee.
- No app-level attempt cap: rate-limiting is deferred to the edge as for the
public /auth/login; the ~1e12 keyspace, single use and short TTL make a
blind app-level cap non-critical.
Phase 6 WebAuthn bind, enrollment-only slice (spec section 14), web app face.
An already-authenticated principal binds a passkey to their own account and
manages the credentials they have bound; email-OTP stays the fallback factor.
- four account routes: POST register/begin mints a credential-creation
challenge, POST register/finish verifies the attestation against the
server-stashed SessionData and binds the credential, GET/DELETE credentials
list and unbind the caller's OWN passkeys. App-tier, principal-scoped (the
body never names a user).
- PasskeyVerifier seam keeps go-webauthn out of this package: ceremony state
crosses as opaque bytes, attestation as an io.Reader, result as a plain
VerifiedCredential. A nil verifier makes begin/finish report 503 so the
authenticated boundary is exercised before the real verifier is wired in.
- the view never leaks the public key; credential_id collisions map to 409.
- OpenAPI: the four paths plus the PasskeyCredential schema, keeping the
served-routes parity gate green.
Scope: ENROLLMENT only. The passkey login/assertion path (proving a passkey
from an unauthenticated state) is deferred; every ceremony here rides on a
known principal.
Tests: handler + challenge state machine against a fake repo and a fake
verifier (no real attestation crypto, no SQL). The decisive assertion is the
session-data round-trip -- the finish body carries no challenge, so the only
path for the stashed blob into FinishRegistration is store-stash then consume,
proving the challenge is server-held and never client-echoed. Also covers
supersede-on-begin, single-use, expiry, 503-unavailable, 409-already-bound,
owner-scoped list/delete, and external-only face separation.
QR scan-to-login is a device-code grant where the QR encodes the existing
short-lived account-link code (spec §B3 player game-login). velocity mints a
code in-game, renders it as a QR, the player scans it on a phone already signed
in to the panel, and that web session's verify writes the durable account_links
row bound to that user. The only new verifiable surface that flow needs is the
completion poll velocity calls to learn the link landed and admit the player.
Add GET /api/v1/internal/account/link/status/{mc_uuid}: a read-only, internal
handleLinkStatus keyed by the verified mc_uuid velocity already holds. It reuses
the existing UserByMCUUID, so it adds no migration and no mutation to the
load-bearing VerifyLinkCode; ErrNotFound maps to {linked:false} (pending /
not-yet-scanned), a hit to {linked:true, user_id}. Keying on the public UUID and
not the scanned code means the read carries no guessing surface and needs no
attempt cap — the internal face already gates it to service callers, and the poll
consumes nothing so a velocity restart re-polls safely.
QR render, limbo collision routing, in-game admit, and the reclaim
inherit-disambiguation stay CODE-ONLY (Java/Velocity) and are labeled as such;
this endpoint reports link completion only.
Document the route in openapi.yaml (x-felis-face internal, x-felis-tier service)
so the parity gate holds, and cover it with a hermetic vertical that proves the
poll reflects the durable link only after the external verify and binds the
verifier's id, plus unknown-uuid, idempotency, and internal-only face separation.
When the configured third-party Yggdrasil and the official Mojang service
issue the same username under different UUIDs, the non-genuine squatter is
displaced in favour of the real Mojang owner (正版优先). This adds the
Go-verifiable data layer of that flow on the internal (velocity) face.
- migration 0006: username_blacklist (barred squatter UUIDs) and
player_data_holds (the displaced account's 30-day data stash), both keyed
by mc_uuid so the genuine Mojang player — identical username, different
UUID — is never caught by the bar.
- POST /api/v1/internal/player/reclaim bars the squatter UUID and stashes
its data in one transaction (all-or-nothing). It is idempotent on a
retried callback and returns the hold's effective expiry — the first
reclaim's window, never a fresh now()+30d — so the rejected player is told
the truth about how long their data is kept.
- GET /api/v1/internal/player/blacklist/{mc_uuid} is the login-gate check
velocity calls to reject a barred squatter before admitting them.
Scope: velocity collision-routing, the limbo prompt, the authlib
dual-backend and the data-inherit flow are code-only (Java plus a QR-bound
device session a row cannot express) and are not part of this slice. Unit
tests cover the handlers and the in-memory repo contract; the Postgres SQL
path is exercised by integration only.
Capture which Yggdrasil authenticated an in-game UUID when a link code is
minted (spec §10 dual-Yggdrasil) and copy it onto the durable account_links
row at verify. The value originates in-game — the web verify side never sees
the authentication — so it threads through account_link_codes, mirroring how
mc_uuid (not user_id) lives on a code.
- migration 0005: add link_auth_source enum + auth_source column on both
account_link_codes and account_links; DEFAULT 'mojang' backfills existing
rows and sets the Mojang-priority default for a mint that omits the field
- mint validates an explicit auth_source (unknown value -> 400); verify
surfaces it in the 200 body and refreshes it on idempotent re-verify
Forced web onboarding proves a player controls an email before it is
bound to their account. POST /api/v1/account/email/start mints a random
6-digit code, mails it (or logs it server-side when no Mailer is wired —
the demo has no SMTP), and POST /api/v1/account/email/verify redeems it,
flipping users.email_verified in the same transaction that consumes the
code.
Brute force is bounded two ways: a 10-minute TTL and a 5-attempt cap,
both enforced in the repo so the fake and Postgres agree. Only the
sha-256 of the code is stored; the digits live only in the email. Both
routes are app-tier external — verifying your own email is scoped to the
principal, never names another user.
Add username+password login for Owner/Operator staff accounts on
op.console, the primary web login when Zero Trust is not in front of the
API. Three handlers form the whole surface: login mints a server-side
session cookie, logout revokes it idempotently, and change-password
re-verifies the current password before rotating the hash and clearing
must_change_password.
- Session cookies are HttpOnly+Secure+SameSite=Lax, host-only, stored
server-side as a SHA-256 hash with a 12h TTL.
- Login is anti-enumeration: every failure runs a uniform bcrypt compare
against a dummy hash and returns the same vague error.
- Credential-bearing writes require Content-Type: application/json,
returning 415 otherwise, to close the cross-site form-POST forgery
vector as a belt to the SameSite cookie.
- Local auth fails closed: login is rejected unless local_auth_enabled
is set, so a Zero-Trust-only deployment never accepts a local password.
- Extend the users table with a nullable password_hash and
must_change_password; staff are role=admin rows with a hash, players
are role=user rows with hash NULL.
- /me now reports must_change_password so the panel can force a
first-login change.
Covered by Go unit tests (handlers, content-type guard, anti-enumeration,
forced-change lockdown) and the OpenAPI route-parity gate.
Machine-readable contract for the felis-api faces. The parity test (internal/api/openapi_test.go) checks every served route against this document's x-felis-face and x-felis-tier, so served and documented routes cannot drift.
