* feat(plugins): add auth capability for plugin-provided OIDC/SAML login
Plugins can now authenticate a visitor against an external IdP (OIDC/SAML)
and contribute a login button to the pre-auth screen:
- new `auth` manifest capability + a capability-gated X-Kandev-Auth-Login
webhook-response directive; the host mints the kandev_session (ADR 0050),
the plugin never receives the raw token. Plugin-set Set-Cookie is dropped.
- auth.Service.AuthenticateExternal: existing-identity / link-by-email / JIT
member provisioning; refuses to auto-link to an admin; verified-email is
the plugin's contract.
- auth_providers manifest block + plugins.SSOProviders() populate the
anonymous boot payload (auth.ssoProviders); the login page renders a
"Continue with <provider>" button per provider.
- ADR 0050 + plugin-manifest / plugin-authoring / auth spec docs.

* docs: exclude publish_review_findings_kandev from public-docs coverage
The native code-review agent (#1957) added the publish_review_findings_kandev
MCP tool but did not update docs/public/coverage.json; that PR did not touch
docs/public so the path-filtered validator never ran. It's an internal review
reporting tool, not a user-facing feature, so record it as an exclusion.

* fix(plugins,auth): address review on SSO directive and JIT provisioning
- takeAuthLoginDirective strips every case variant of X-Kandev-Auth-Login and
rejects (403) when a plugin sends more than one, so no variant leaks to the
browser and login never uses a nondeterministically-picked assertion.
- provisionExternalUser rolls back the just-created user when the identity
insert fails (transient error or a lost UNIQUE(provider,subject) race) and
resolves to the winning identity, so no account is left without a login and
no email is reserved by an unusable row. Adds userstore.DeleteUser.
- auth spec: mark the login-page SSO buttons + provider discovery as landed.

* fix(auth): scope in-session agent MCP calls to the task owner
The MCP tools an agent gets automatically inside its own session are
relayed over the agent's WebSocket stream, which carries no credential.
The backend dispatched them on the raw stream context, so the task
service saw no identity — its signal for an internal caller (event bus,
pollers, office schedulers) — and served the request unscoped. An agent
that supplied another user's task_id or workflow_id was given their
data, violating the rule that knowing an ID must not grant access.
Resolve the owning user from the stream's own AgentExecution (task ->
workspace -> owner) and attach that real stored identity before
dispatch, so the existing authorize* checks apply exactly as they do on
the PAT-authenticated /mcp endpoint. The owning task never comes from
the agent-supplied payload: honoring a payload session_id would let an
agent name another user's session and inherit their identity.
Tool handlers are unchanged. Auth disabled stays unscoped, unclaimed
pre-auth workspaces stay visible to everyone, and a lookup failure
denies the dispatch rather than falling back to full access.

* fix(auth): never leave in-session MCP dispatch unscoped
Review follow-up. Three paths still returned an identity-free context
under enforced auth, and "no identity" is exactly what the task service
reads as an internal caller and serves unscoped:
- Unowned workspace. CreateWorkspace only stamps an owner for scoped
callers, so internal callers keep producing owner_id='' rows after
setup. Those streams got full cross-user access. Scope them to a
sentinel user ID no account can hold: the service's "empty owner_id or
my own ID" rule then limits them to the unowned rows that are public
by the compatibility contract, and nothing else.
- Task with no workspace. Same treatment, same reasoning.
- Missing task or workspace row. A lookup that reports not-found as
(nil, nil) fell through to unscoped; treat it as a resolution failure.
Also deny, rather than fabricate a member identity, when the owner's
account is gone or disabled. Disabling a user revokes their sessions and
PATs, so a still-running agent session was the one remaining way into
their workspace.

* feat(auth): add auth core — identities, sessions, PATs, invites, mode state machine
Phase 1 of opt-in authentication + multi-user segregation:
- internal/auth: argon2id password hashing (PHC), opaque session/PAT tokens
(SHA-256 at rest), login rate limiter, auth-mode state machine
(disabled/setup/enabled), setup-wizard promotion of the pre-auth
default-user row into the admin account, invites, admin user management
with last-admin guard.
- internal/auth/store: auth_identities (OIDC-ready), auth_sessions,
auth_api_tokens, auth_invites tables (SQLite+Postgres dialects).
- internal/auth/authn: request-identity plumbing (gin + plain contexts),
RequireAdmin middleware.
- users table: display_name/role/status columns via new MigrateLogger
wiring; AccountRepository surface (consumer-scoped, keeps existing
Repository fakes untouched).
- config: AuthConfig.Required/SessionTTLHours/CookieName
(KANDEV_AUTH_REQUIRED), FeaturesConfig.Auth; profiles.yaml + runtime
flag registry entry for KANDEV_FEATURES_AUTH.

* feat(auth): enforce opt-in auth over HTTP — middleware, auth API, boot payload
Phase 2 of opt-in authentication + multi-user segregation:
- internal/auth/httpmw: global gin middleware after CORS. Disabled mode
injects the synthetic single-user admin identity (behavior unchanged);
enabled mode resolves session cookie then PAT bearer, with an explicit
allowlist (health, SPA bootstrap reads, credential endpoints,
self-authenticating webhooks), deferral for WS/proxy upgrades and
office agent JWTs, and SPA shell availability for the login page.
- internal/auth/httpapi: full auth surface — setup wizard, login/logout,
me, password change, sessions, PATs, invites (mint/preview/accept),
auth settings (enable/disable), admin user management.
- Boot payload: initialState.auth block always present; unauthenticated
visitors on auth-enabled instances get features+auth only (no data).
- External MCP: PAT required once auth is enabled (open while disabled).
- Admin guards on destructive system routes and runtime-flag overrides.
- Startup warning when bound non-loopback with auth disabled
(ServerConfig.NonLoopbackBinds fail-closed nudge).
- Wiring: auth store in Repositories, auth service in Services,
ClaimUnownedWorkspaces backfill on the task repository.

* feat(auth): per-user workspace scoping across HTTP services
Phase 3 of opt-in authentication + multi-user segregation:
- Task service: workspaces, workflows, repositories, and tasks are scoped
to the request identity (owner-only visibility; pre-auth unowned rows
stay shared). Denials use *NotFound sentinels - no existence leak.
Internal callers and the disabled-mode synthetic identity remain
unscoped, preserving behavior exactly when auth is off.
- CreateWorkspace stamps the authenticated caller as owner.
- Session chokepoint: lifecycle Manager.GetOrEnsureExecution runs a
settable session-access check covering shell/files/ports/vscode/LSP.
- Secrets: per-user user_id column, scoped CRUD/list, ClaimUnowned wired
into the setup-wizard backfills.
- Boot payload inherits scoping automatically.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(auth): scope WebSocket gateway to authenticated users
Phase 4 of opt-in authentication + multi-user segregation:
- Connection auth: /ws, /terminal, /lsp, /vscode, /port-proxy routes are
guarded when auth is enabled - session cookie (same-origin upgrade),
resolved identity from the HTTP middleware, or ?token=<PAT> for
headerless programmatic clients; JSON 401 before any upgrade.
- Client identity: every WS client carries its authn.Identity; dispatched
RPC actions (workspace.list, task CRUD, ...) run under a context
carrying it, so WS RPC gets the same per-user scoping as HTTP.
- Subscription checks: task/session subscribe+focus verify workspace
visibility via the task service; user topic subscriptions are pinned to
the client's own user.
- Broadcast routing: new Hub.BroadcastToWorkspace routes workspace-scoped
events (task/workflow/repo/office/session-state) to the owner's clients
only, with safe fallbacks (unowned/unresolvable -> broadcast) so events
never vanish; instance-wide events (executors, environments, agent
profiles, system jobs) stay global by design.
- Replaced the long-standing discarded-token TODO in HandleConnection.

* docs(auth): add feature spec and backend architecture notes for opt-in auth
- docs/specs/auth/spec.md: product behavior (opt-in, setup wizard,
per-user workspaces, sessions/PATs, invites, public surface, v1 limits)
- apps/backend/AGENTS.md: internal/auth package layout + scoping rules
for new service entry points and WS broadcast call sites
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs(auth): public documentation for opt-in authentication
- New docs/public/authentication.md: enabling, users & invites, PATs,
public endpoints, limitations, disabling
- run-as-a-service.md: network-security note now points at the real
authentication boundary instead of reverse-proxy-only guidance
- meta.json: nav entry under Configure Kandev
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs(auth): ADR for opt-in authentication architecture
Records the load-bearing choices: mode state machine + synthetic identity
in disabled mode, opaque DB-backed credentials over JWTs, default-user
promotion at setup, service-layer scoping with no-admin-bypass, and the
explicit public allowlist.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(web): auth UI — login, setup wizard, invites, users & account settings
Adds the frontend half of opt-in authentication: a pre-auth gate in
main.tsx that renders the setup wizard or login/invite pages instead of
the app shell whenever the boot payload's auth block says so, a new
`auth` store slice + feature flag mirroring the backend's StatePayload,
credentialed fetch (`credentials: "include"`) with a 401 handler that
clears the session and redirects to /login, and a full auth-api.ts
client for the /api/v1/auth and /api/v1/users routes.
Settings additions: a System > Users page (list/create/disable/promote
users, invite-link dialog) and System > Authentication page (enable/
disable with confirm + env-locked banner), gated on the `auth` feature
flag and admin role. A new Account sidebar group (Profile & Password,
API Tokens) is shown to signed-in users once auth is enabled.

* test(auth): E2E lifecycle suite + fix workspace event WS leak it caught
New dedicated Playwright auth project (backend restarts with
KANDEV_AUTH_REQUIRED=true, isolated from the tokenless default suite):
setup-mode boot gating, admin setup wizard, login/logout + bad
credentials, PATs, admin-surface authorization, anonymous WS rejection,
UI login flow, and the acceptance test - two-user segregation across
HTTP, boot payload, and WebSocket.
The segregation spec immediately caught a real leak: workspace.* event
payloads carry their ID as 'id' (the payload IS the workspace DTO), not
'workspace_id', so BroadcastToWorkspace fell back to broadcast-to-all
for workspace create/update/delete. Fixed with action-aware extraction
plus a unit regression test.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(auth): close cross-user access gaps found in security audit
Two independent security audits of the auth branch found several
authorization gaps where session/workspace-scoped surfaces were not wired
to the new per-user chokepoint. All fixed:
- IDOR on reverse-proxy/terminal routes (vscode, port-proxy, terminal):
these resolve executions via GetExecutionBySessionID /
GetOrEnsureExecutionForEnvironment / EnsurePassthroughExecution, which
skipped the session-access check that only GetOrEnsureExecution ran. Added
the check inside the env/passthrough resolvers (before the cache
short-circuit) and an explicit CheckSessionAccess gate in the two bare-lookup
proxy handlers. An authenticated non-owner can no longer reach another
user's IDE, forwarded ports, or shell.
- Cross-user agent-conversation read: ListMessages / ListMessagesPaginated /
SearchMessages now authorize the session.
- Cross-user repository-script read/inject: script CRUD now authorizes the
parent repository's workspace.
- Office HTTP surface: a group middleware enforces workspace ownership on
:wsId routes for real users (agent-JWT callers keep their claim scoping).
- Login rate-limit bypass: SetTrustedProxies(nil) so a spoofed
X-Forwarded-For can't rotate the limiter key on a directly-reachable
backend.
- Invite double-provisioning race: MarkInviteUsed is now the atomic
serialization point (consumed before user creation).
- Setup wizard: serialized with a mutex so concurrent first-visitors can't
corrupt the promoted admin profile.
- Log sanitizer: explicit kandev_pat_ redaction rule.
Regression tests added for message/script scoping and the
execution-access-before-cache invariant. Auth E2E (incl. two-user
segregation) still green.

* fix(auth): scope repository active-session-count endpoint
GET /api/v1/repositories/:id/active-session-count went through
CountActiveSessionsByRepository, which was not identity-scoped - a
cross-user info leak of another owner's active session counts. Added the
same authorizeRepositoryID gate the script routes use.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(auth): add json tags to auth store models — omit digests, fix token UI
The auth store structs (APIToken, Invite, LoginIdentity, Session) had db:
tags but no json: tags, so the handlers that serialize them directly sent
Go-cased keys (CreatedAt, Name) AND leaked the SHA-256/password digests to
clients. Two consequences:
- The API-tokens UI showed 'Invalid Date' and an empty name (frontend reads
created_at/name).
- token_sha256 / password_hash were serialized in list responses.
Added json tags with snake_case keys the frontend reads and json:"-" on
every credential digest. Regression test asserts digests never serialize and
the snake_case timestamp/name keys are present. Also adds the
auth-screenshots capture spec (artifacts gitignored).

* feat(web): move auth enable into feature toggles; show current user in sidebar
Remove the standalone Authentication settings page and its dedicated
settings/get-auth-settings API surface now that enabling auth lives in the
Feature Toggles system, and drop env_required now that /auth/me no longer
returns it. Add a current-user chip with a logout action to the sidebar
footer, shown only in enabled auth mode.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* refactor(auth): make features.auth the single on/off control
Per review feedback: authentication configuration now lives entirely in
the existing Feature Toggles system rather than a separate Authentication
settings section.
- The auth mode is derived from the features.auth runtime flag
(KANDEV_FEATURES_AUTH): off -> disabled, on+no-admin -> setup,
on+admin -> enabled. Removed the parallel auth.mode system setting,
the SetEnabled service method, GET/PATCH /api/v1/auth/settings, the
AuthConfig.Required field, KANDEV_AUTH_REQUIRED, and the auth service's
Settings-store dependency and EnvRequired/env_required.
- The features.auth registry entry is re-described as the actual enable
switch (high-risk, restart-required) and defaults off in every profile
(dev was previously true — that only revealed UI before; now it would
enforce, so it must be an explicit opt-in).
- Setup no longer persists a mode; completing the wizard creates the admin
and the mode auto-derives to enabled.
- Startup 'exposed without auth' warning + all docs (public guide,
run-as-a-service, spec, ADR, AGENTS.md) point at the feature toggle.
- E2E: auth specs use KANDEV_FEATURES_AUTH; screenshot spec captures the
Feature Toggles page instead of the removed Authentication page; the
member-restriction assertion targets an admin invite route.
- Tests updated across service/httpmw/httpapi/profiles for the derived
mode; full suite green (only pre-existing sandbox-FS failures remain).

* fix(auth): complete cross-user isolation — integrations, automation, plan/walkthrough, session reads
A follow-up isolation audit found that per-user scoping had been wired into
the task service, secrets, office, and the WS gateway — but several
workspace/task/session-scoped surfaces still resolved a caller-supplied ID
with no ownership gate. Closed all of them; cross-user access now returns
404 across the board.
- Integrations (jira/linear/sentry/slack/azure-devops/gitlab/github/
workflow-sync): a global middleware authorizes the workspace_id (query, or
gitlab's /workspaces/:id/ path) on those route groups. Previously a member
who knew another user's workspace ID could read/overwrite their integration
connection config and watches.
- Automation: workspace-authorizer seam gates get/list/create/update/delete/
enable/disable, triggers, run history, and — critically — the webhook
secret. Was fully cross-tenant over WS before.
- Task plans (PlanService) and walkthroughs (WalkthroughService): task-
authorizer seam on every read/write. These bypassed the task service.
- Session reads that hit the repo directly — session turns, task context,
git snapshots, file reviews — now call AuthorizeSession/TaskAccess.
Internal callers (pollers, schedulers, MCP) carry no identity and stay
unscoped; disabled mode is unaffected. Regression tests added
(plan/walkthrough scoping, automation authorizer matrix, integration path
extraction) and the two-user E2E now asserts integration routes are shielded.
Docs (spec, ADR, public guide) updated to state what is isolated and that
filesystem/agent-credential isolation remains an OS-level limitation.

* fix(web): current-user chip uses border hover, not accent fill
The sidebar current-user chip used hover:bg-accent (a purpleish fill).
Switch to the border-hover idiom used elsewhere (border border-transparent
-> hover:border-border) with the neutral hover:bg-muted/50 the adjacent
workspace picker uses, so the hover reads as a subtle outline instead of a
colored background. Screenshot spec now captures the chip hover state.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(web): right-align current-user chip in the sidebar footer
Push the user chip to the far right of the expanded footer (ml-auto) so it
sits opposite the left-aligned icon buttons; collapsed mode keeps the
centered vertical stack unchanged.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(auth): reject synthetic identity on management routes and scope office run broadcasts
Address code-review findings on the opt-in authentication PR:
- P1: while auth is disabled the middleware injects a synthetic admin
(RoleAdmin), and RequireAdmin alone let it through — so anyone hitting a
not-yet-enabled instance could mint a PAT or plant an admin that survives
enablement and hijacks first-run setup. Add authn.RequireRealIdentity and
guard the credential/session/user-management routes with it (public
bootstrap routes stay reachable). Responds 404 while disabled.
- P1: office run events carry task_id but no workspace_id, so they fell back
to a global broadcast and leaked across users. Resolve the workspace from
the task and route via the new Hub.BroadcastToWorkspaceOrDrop, which fails
closed (drops rather than global-broadcasts) when the workspace is unknown
and auth is enforced.
- nit: type createAuthSlice as a single-arg creator and call it with just set.
Also register the authentication docs page and its settings routes in
docs/public/coverage.json so the public-docs validator passes.
