* 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.

* 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.

* refactor(backend): classify errors via sentinels instead of substring matches
Introduce package-local sentinel errors in the github, task repo, agent
lifecycle, and office/skills packages. Producers wrap with fmt.Errorf("%w: ...")
so callers can classify via errors.Is/errors.As instead of brittle
strings.Contains(err.Error(), ...) checks that break on library upgrades.
Sentinels added (or relocated to errors.go):
- github: ErrInvalidToken (new); ErrInvalidPRURL, ErrTaskNotFound, ErrSelfApprove
moved from service.go.
- task/repository/sqlite: ErrTaskNotFound, ErrOfficeSessionRaceConflict.
- lifecycle: ErrAgentAlreadyRunning, ErrAgentReported.
- office/skills: ErrSkillNotFound, ErrSkillFileNotFound.
Consumers updated to errors.Is/errors.As across orchestrator, task/handlers,
github, and office/skills. AssociateExistingPRByURL switches %v -> %w so the
inner parsePRURL error stays in the chain. process_handlers now uses
errors.Is(err, syscall.ECONNREFUSED) and lifecycle.ErrNoExecutionForSession
plus a small isTimeoutError helper backed by errors.As.
A new taskDeleterAdapter in cmd/kandev/turn_adapters.go translates
taskrepo.ErrTaskNotFound to github.ErrTaskNotFound at the wiring boundary,
avoiding a layering violation between the github and task packages.
The one remaining substring check, in CreateTaskSession, is encapsulated
inside the repo and converts the SQLite UNIQUE-violation message into the
typed ErrOfficeSessionRaceConflict sentinel so callers never see the driver
string.

* test(backend): add TestErrorsAreClassifiable for refactored packages
Pin the new sentinel-based contract for each refactored package. Each test
exercises the producer paths and asserts errors.Is reaches the sentinel
through the wrap chain, and (where applicable) confirms untyped lookalike
strings no longer classify.
- github: isTaskNotFound, AssociateExistingPRByURL/ErrInvalidPRURL,
ConfigureToken/ErrInvalidToken (using a noop secret manager).
- task/repository/sqlite: GetTask, DeleteTask, UpdateTaskState wrap
ErrTaskNotFound.
- task/handlers: isNotFound + isAgentReportedError follow the typed chain.
- orchestrator: each isXError classifies exact + wrapped sentinels, rejects
untyped lookalikes.
- office/skills: readUserHomeSkillInventoryFile wraps ErrSkillFileNotFound;
ErrSkillNotFound survives fmt.Errorf("%w", ...).
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* test(github): drop network-hitting subtest from errors_test
The "ConfigureToken wraps ErrInvalidToken when validation fails" subtest
constructed a real PATClient and called GetAuthenticatedUser, which makes
a live HTTP request to api.github.com. That's flaky in CI / offline dev
and violates the unit-test boundary (caught in review).
Replace with a sentinel-survives-wrap-pattern check that locks in the
exact %w/%w shape used by ConfigureToken, plus an assertion that the
inner cause stays reachable through errors.Is. The full ConfigureToken
flow stays covered by service_token_test.go and integration tests.
Remove the now-unused noopSecretManager stub type.

* fix(task): restore "timed out" UX for plain-fmt.Errorf timeout producers
The original createPromptErrorMessage rendered the friendly "Request timed
out…" hint via strings.Contains(err.Error(), "timeout"). The refactor
replaced it with errors.Is(context.DeadlineExceeded) + a net.Error
Timeout() helper — strictly typed. But several upstream producers along
the prompt path (service.WaitForSessionReady, agent-stream connect waits
in lifecycle/session.go and manager_interaction.go, agentctl health waits
in agentctl/client.go and launcher.go, the orchestrator's own
waitForSessionReady) return plain fmt.Errorf("timeout …") with no typed
Timeout() method, so the typed check missed them and the user saw the
generic "Failed to send message to agent" instead.
Add a substring fallback inside isTimeoutError as a UX safety net while
keeping the primary typed paths intact. Lock the contract with table
tests covering all three classes (net.Error timeout, plain string,
context.DeadlineExceeded) so any future trim of the fallback breaks
loudly. Migrating each upstream producer to a typed sentinel is tracked
as out-of-scope follow-up.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* test(backend): tighten classification tests to exercise typed-sentinel contracts
Addresses bot-review feedback on PR #1057:
- task/handlers/errors_test.go: cover all four not-found sentinels
(taskrepo.ErrTaskNotFound, service.ErrDocumentNotFound,
service.ErrTaskPlanNotFound, service.ErrRevisionNotFound) in
TestErrorsAreClassifiable via a table-driven loop, instead of only
one. Drop the spurious Deadline() *time.Time method on timeoutNetErr
— it isn't part of net.Error and the existing `var _ net.Error =
timeoutNetErr{}` line already pins the interface.
- orchestrator/scheduler/scheduler_test.go: testTaskRepository was
still returning the local scheduler.ErrTaskNotFound, which doesn't
satisfy the production processTasks check (now errors.Is on
taskrepo.ErrTaskNotFound). Mirror the real sqlite repo's wrap so the
mock and prod paths agree. The local scheduler.ErrTaskNotFound is
truly dead after that, so drop it from scheduler.go.
- office/skills: the wrap-pattern subtest in errors_test.go was only
testing fmt.Errorf, not production code. Move the contract assertion
to service_test.go (external skills_test package) where it drives
the real GetSkillFromConfig lookup path against an empty in-memory
repository.

* refactor(backend): drop redundant context.DeadlineExceeded check and fix doc grammar
Addresses bot-review feedback on PR #1057:
- task/handlers/message_handlers.go::createPromptErrorMessage: the
explicit errors.Is(promptErr, context.DeadlineExceeded) is redundant
with isTimeoutError, which already matches via errors.As against
Timeout() — context.DeadlineExceeded implements Timeout()==true.
Inline comment documents the consolidation.
- github/errors.go: fix grammar in the ErrTaskNotFound doc comment
("is the sentinel cleanup paths check for to distinguish" →
"is the sentinel that cleanup paths check to distinguish").
