Current scope

Naruon owns the browser-facing authentication product surface; Keyverse remains the identity/authentication authority. The supported federated path remains Authorization Code + PKCE. The earlier Direct Access Grants / OAuth2 ROPC experiment is retained only as history, not as a releasable or dormant authentication mechanism.

Current protected base: develop@042b0c70531b229af3acbd0421a2f23098d848b3.
Current exact head: d93aabcc134ae461cf7f42d6cf26c6ca29deb9f5.
Lifecycle: Draft / credential authority and credential-solicitation UI repaired / supported-SSO Settings rehydration repaired / real-browser popup contract added and awaiting hosted GREEN.

RED → causal repair

RFC 9700 §2.4 and RFC 10017 §7.3 prohibit the Resource Owner Password Credentials grant. This branch previously kept public password routes wired to exchangePasswordForSessionResponse and retained Naruon-local password registration authority.

  • RED f0bdb90ce775488495423d0c5ee0c7aae0e1b881: reject exchangePasswordForSessionResponse / grant_type=password in both public password endpoints.
  • 6832c85525ec2b68ee45d474f5e3f75e0d80d452 / fab63c9dc5cc206fdf0268eb48cfdf6bfce0ffa4: login and signup keep same-origin rejection, then fail closed with typed HTTP 503 before parsing or forwarding credentials.
  • 9deb2a487e572817df8a8566febf21a563addfe6 / 77e4be28df01d042b42954353375a75650c16e4e: route contracts verify fail-closed behavior, no session cookie, malformed-body non-parsing, and same-origin rejection.
  • d4574cbf02bc4450568b3066afe33d29b317dba7: remove the obsolete upstream-signup route contract.
  • b8e99161142d8e0a5ef3ea1fe9bb8aef5d52af3e: make ADR-0005 narrative code-current with fail-closed public routes.
  • RED 768b29af07a290231ce5a313de3ebeac8e2aa851 → fix ee4c68240e95fc669ef0760718fe05dd952986cd: ADR index can no longer claim Accepted or password login/signup working end-to-end; it is Proposed / BLOCKED-UPSTREAM.
  • RED ff18d276f32b45d1c35a3a775a75ccedef5489c9: reject dormant ROPC and Naruon-local password-registration authority, not only reachable route calls.
  • 95173847f3b5428debae2f1ee1674c0277692e10, f9e29de32684ae3e6739b0f425391125e87a8733, c1242c71398fc1fddbf6c7e9d86873aaeec42fbb: remove obsolete password-registration tests/client and its bearer-token runtime surface.
  • 5f72fb4676cd2bf0d7bcaa85d9bb2c5dc3ecf71e: remove exchangePasswordForSessionResponse, grant_type=password, and password-only parsing helpers from the shared OIDC module while preserving Authorization Code + PKCE helpers.
  • a5a8aa2d942595b09826841d2322c06b5c70797e: update ADR-0005 to record the removed dormant credential authority.
  • RED 01763d194f394fad95d61d1b2090039acbb749dc: executable buyer-surface contract rejects password inputs/submit handlers while capability is unavailable and requires an explicit unavailable-state message.
  • dd0411c5f495d97cd38021aecac2f275fbb0aaed: remove the password login/signup form state, submit handlers, and credential fields; replace them with a non-interactive unavailable-state section while preserving the supported Keyverse SSO path.
  • Direct child a09ad45fe755a0bffee1b21fc6e22a19bb1a90ba: repair the unrelated POP3 secret-field typo (popPasswordpop3Password) found during immediate commit-diff inspection.
  • Intervening direct child 330c662d6c3e1f811b1a61dda9f0b6acf806e612: repair the executable ROPC policy test itself. sourceFile("../../oidc/shared.ts") resolved to the nonexistent frontend/src/app/oidc/shared.ts; the correct current-tree path is ../oidc/shared.tsfrontend/src/app/auth/oidc/shared.ts. This is adopted as a valid one-line test repair, not treated as a race.
  • 44abc04c4fff375c42a3345f2d1e4aecdd3b9d8a: add peer-reviewed TRACEABILITY to ADR-0005. Normative authority remains RFC 9700/RFC 10017; Fett, Küsters, & Schmitz (CCS 2016) supports OAuth authentication/session-integrity reasoning, and Bonneau et al. (IEEE S&P 2012) supports evaluating successor authentication across security, usability, and deployability.
  • Intervening direct child 16470fc20fd44b82e3968c9dcf686aa730baae2f: repair the still-valid Settings rehydration finding. The mount-time authenticated Settings fetches are factored into loadAccountSettings; after startOidcLogin succeeds, Naruon refreshes session claims, resets the relevant loading states, and re-fetches runner config, operational signals, account config, calendar/WebDAV readiness, and LLM provider configuration. The same commit adds a RED→GREEN regression in SettingsLayout.test.tsx: account config first fails with 401 while anonymous, then succeeds after mocked SSO completion without remount or full-page reload.
  • b7f7bcb9c33a60fba61fe5dcf331510658701284: add real Chromium/Playwright acceptance for the remaining browser interaction contract. It covers successful popup completion over the flow-scoped BroadcastChannel plus popup closure, explicit user-closes-popup failure surfaced in the parent tab, and popup-blocked same-tab callback fallback without closing the application page.
  • d93aabcc134ae461cf7f42d6cf26c6ca29deb9f5: wire that focused browser contract into Naruon's existing Application CI frontend job after Chromium installation, with localhost-only OIDC bootstrap values. The test intercepts the Naruon OIDC boundary; it does not consume a mutable Keyverse source head or pretend to validate an unreleased password/headless contract.

No force-push, destructive rebase, self-approval, dummy/requeue commit, or gate weakening was used.

Review repair

The buyer-visible ROPC/password-form finding is resolved: SettingsLayout no longer solicits credentials for an intentionally unavailable capability. The Settings-stay-failed-after-login finding is resolved by 16470fc20... with executable regression coverage. The former E2E-coverage finding now has a real-browser contract in frontend/tests/e2e/auth-sso-popup.spec.ts; it remains a merge gate until the new exact-head hosted Application CI run executes that test successfully. Obsolete account-unification, ROPC, opener, callback-mode, and related route findings are resolved where their affected authority has been removed or repaired.

Canonical owner boundary

ContextualWisdomLab/keyverse#128 remains the owner lane for a replacement design and is not an immutable released dependency. Until Keyverse publishes a standards-compliant headless authentication/session contract, Naruon does not restore ROPC, copy Keyverse identity semantics, or consume a mutable owner head.

Remaining before Ready

  1. Consume only an immutable released Keyverse replacement contract when one exists; otherwise keep password login/signup fail closed and non-interactive.
  2. Obtain terminal-success hosted evidence for the newly wired popup success/closure/blocked-popup browser contract on this exact head.
  3. Obtain every other then-live exact-head unit/type/lint/build/security/SAST/CodeQL/review gate, resolve every still-valid review thread, and obtain post-last-push independent approval. Predecessor evidence does not transfer.

Current exact-head pull-request workflows for Application CI, Security Scan, Dependency Review, Semgrep, Bandit, OSV, Scorecard, and Docker validation exist; at the latest fresh read Application CI and most peers were queued and Security Scan was pending. Queued/pending evidence is non-passing.

…kend

Corrects course from an earlier Keycloak-theme-reskin attempt: even a
visually-identical Keycloak theme is still Keycloak's own server rendering
the page, which product direction explicitly rejected. The requirement is
naruon's own frontend rendering 100% of the login UI with zero
Keycloak-rendered HTML, backed by naruon's own server talking to Keyverse
purely as an API.

Investigated whether Keyverse's WebAuthn passwordless mechanism could serve
a naruon-owned form first — it cannot, structurally: Keycloak's
authentication ceremony runs inside its own login-actions flow bound to a
server-side AuthenticationSessionModel, with no public REST pair for the
ceremony outside that flow (confirmed against keyverse's own realm config
and passwordless-policy.md, and against Keycloak's WebAuthn architecture).
Direct Access Grants (ROPC) is the only Keycloak-native mechanism that fits
the zero-Keycloak-HTML requirement, so this adds:

- Settings > Security > "Naruon 계정으로 로그인": naruon's own email/password
  form, submitting to a new naruon backend route, never a Keycloak URL.
- frontend/src/app/auth/password/login/route.ts: exchanges the credentials
  server-side against Keycloak's token endpoint (grant_type=password),
  reusing the same SSRF-hardened, DNS-pinned token client and trusted-
  endpoint validation the authorization-code callback already uses (both
  now share those helpers via oidc/shared.ts). The password is never
  logged, cached, or persisted; failures collapse into one generic
  "invalid credentials" response so the error surface can't enumerate
  users or probe configuration.
- The existing federated-SSO redirect (renamed "Keyverse SSO로 로그인" for
  clarity, from "OIDC 로그인") is kept, not removed — it remains the only
  path for brokered/federated identities, which have no local password.
  Its popup-based improvement from earlier in this effort (the naruon tab
  no longer navigates away) still applies there.

This does not make login functional yet: no account in Keyverse's realm has
a password credential today, so every attempt currently fails closed with a
generic error. A companion, separately-reviewed keyverse-side change
(github.com/ContextualWisdomLab/keyverse/pull/128) scopes a
directAccessGrantsEnabled exception to naruon-web only; issuing actual
password credentials is flagged there as further follow-up work. See
docs/adr/0005-naruon-owned-password-login-form.md for the full decision
record, including the theme reskin that was built, screenshot-verified, and
then explicitly rejected.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 2516c

The new authentication flows can expose credentials, consume excessive server resources, and break federated sign-in behavior. These issues should be resolved before merge.

ADR-0005 shipped a real but non-functional login route: naruon-web's
Direct Access Grants was enabled keyverse-side (keyverse#0014), but no
account in the cwl realm had a password credential, so every login
attempt failed closed. A companion keyverse change
(keyverse#0015, PR ContextualWisdomLab/keyverse#128) adds a scoped
POST /registration/accounts/password endpoint that creates an account
with an immediately usable password credential. This wires naruon to it.

- New "Naruon 계정 만들기" section in Settings > 개발자, alongside the
  existing login form — email/password/optional-name, same zero-Keycloak-
  HTML posture. Copy states plainly that email verification and abuse
  hardening are not yet provided (keyverse#0015's explicit deferrals),
  rather than presenting the slice as production-complete.
- frontend/src/app/auth/password/signup/route.ts: calls account-
  unification's password-registration endpoint server-side through a new
  frontend/src/lib/account-unification-client.ts (validates the internal
  URL is HTTPS/non-private outside dev, maps upstream error status/detail
  to naruon's own error-code taxonomy), then immediately reuses the same
  Direct Access Grants exchange login uses
  (exchangePasswordForSessionResponse, extracted from the login route into
  oidc/shared.ts so both routes share one implementation) — signup ends
  with a signed naruon_session cookie, not a second manual login step.
- Neither the signup form's password field nor the backend route logs,
  caches, or persists the raw password beyond the single upstream request.

Tests: new route tests for account-unification-client.ts and the signup
route (success path, unconfigured-503, validation-422 detail forwarding,
409/429/502 mapping), plus the extracted shared exchange helper covered
by the existing login route tests. pnpm test/lint/typecheck/build all
pass.

Security merge blocker — exact head 705644d7d92e5d09ce42253d777b6208387d43dd implements grant_type=password as the production login path and ADR-0005 calls Direct Access Grants the mechanism that satisfies the zero-Keycloak-HTML requirement. The current OAuth Security BCP supersedes that architectural premise: RFC 9700 §2.4 states that the Resource Owner Password Credentials grant MUST NOT be used because it exposes the resource-owner credential to the client, expands leak surface, and is incompatible with modern multi-step/WebAuthn authentication. ADR-0005 cites RFC 6749 (2012) but not RFC 9700 (2025).

RED acceptance: add a production-boundary architecture/security regression that fails while naruon production auth submits grant_type=password; require the ADR/reference ledger to include RFC 9700 and reject ROPC as a supported production auth flow.

GREEN acceptance: resolve the product/security conflict explicitly. Either retain Authorization Code + PKCE with authentication executed by Keyverse/Keycloak so naruon never receives the user's password, or first build/review a genuine first-party Keyverse authentication ceremony/API and consume it through a non-ROPC OAuth/OIDC design. Wrapping or renaming the same password grant is not a repair. Keep the existing SSRF, generic-error, no-password-logging, replay/rate-limit, MFA/step-up, and session-token checks, then reacquire all exact-head UI/security/coverage evidence.

APA 7 primary authority: Lodderstedt, T., Bradley, J., Labunets, A., & Fett, D. (2025). Best current practice for OAuth 2.0 security (RFC 9700), §2.4. RFC Editor. https://www.rfc-editor.org/rfc/rfc9700.html

This is a real product/security decision because the stated zero-Keycloak-rendered-HTML requirement conflicts with the standards-compliant OAuth path currently available. Do not merge the current head until that conflict is resolved.

Fresh security/standards review finds a merge-blocking architecture defect in the password-login mechanism, independent of the UI requirement.

This PR deliberately implements Keycloak Direct Access Grants / OAuth 2.0 Resource Owner Password Credentials (grant_type=password) so Naruon can render its own login form. That flow is no longer admissible for a new production authentication design: RFC 9700, §2.4 (Best Current Practice for OAuth 2.0 Security) says the Resource Owner Password Credentials grant MUST NOT be used because it exposes the resource owner's credentials to the client and expands the credential-leak surface; it also cannot cleanly support MFA/WebAuthn/multi-step authentication. Keycloak's current OIDC documentation repeats that requirement and recommends Authorization Code or Device Authorization instead. The March 2026 OAuth 2.1 draft omits ROPC entirely for the same reason.

The product requirement remains valid: Naruon should render its own login/signup/recovery UI while Keyverse remains the canonical identity backend. The repair should therefore happen at the Keyverse contract boundary rather than by enabling a prohibited OAuth grant. In particular, do not reinterpret this finding as permission to fall back to a Keycloak-hosted branded page if the product contract forbids that. Advance Keyverse to a supported headless authentication/session contract suitable for Naruon-owned UI (for example an owner-defined passkey/WebAuthn ceremony and recovery/session API bound to the Naruon origin, or another standards-compliant owner contract), then consume only that released/versioned API from Naruon. Authorization Code + PKCE remains valid for federated/SSO flows where browser authorization-server interaction is acceptable.

Required RED/GREEN for this lane: RED must prove no Naruon login/signup path submits grant_type=password or enables Direct Access Grants; GREEN must preserve the Naruon-rendered form, generic anti-enumeration errors, credential non-logging, session-cookie protections, MFA/passkey/recovery extensibility, and Keyverse ownership using its released contract. Update the ADR/SECURITY/THREAT_MODEL/TRACEABILITY with RFC 9700 §2.4 and current Keycloak guidance before merge.

Companion owner PR ContextualWisdomLab/keyverse#128 currently enables the same Direct Access Grants exception and therefore needs the canonical owner repair. This comment is owner-path advancement only; no write was made to this externally owned Naruon branch.

The Devin finding "Created accounts appear to fail" (signup/route.ts:102-105) traces back to a root-cause bug on the Keyverse side, not this route's error handling: keyverse#128's new /registration/accounts/password endpoint created accounts that inherited the realm's default WebAuthn-passwordless required action, which Direct Access Grants can't complete — so the immediate post-signup login this route relies on (exchangePasswordForSessionResponse) was failing for every new account, not just on transient errors.

Fixed in keyverse@7c1939d (pushed to keyverse#128): new password-registered accounts now get required_actions=[] explicitly instead of inheriting the passwordless default. Once that PR merges, the specific "account created but login fails" symptom here should resolve without any change on this side.

Left as-is for now, not fixed in this PR: the other independently-real findings (DNS rebinding in the registration fetch, no-Origin-check cross-site session replacement, unbounded request bodies, noopener=false on the identity popup, long-name truncation, tab-closing logic) — those are naruon-side issues distinct from the Keyverse bug above and need their own pass.

Devin Review flagged this on the PR: POST /auth/password/login and
/auth/password/signup accepted credential submissions with no Origin/
Referer check. Both are JSON routes read via request.json(), which -- per
the Fetch API spec -- parses the body regardless of the declared
Content-Type header. A cross-site attacker can send Content-Type: text/plain
(a CORS-"simple" content type, no preflight) with a JSON-formatted body and
still hit request.json() successfully, so the browser's own CORS
preflight never protected these routes the way it looks like it should.

For login this is login CSRF: an attacker's page silently submits the
attacker's own credentials, and the victim's browser ends up signed into
the attacker's account without their knowledge. For signup it's account
creation as a side effect of visiting an attacker's page.

Extracted app/api/[...path]/route.ts's existing (already-correct, already
tested) sameOriginStateChangingRequest CSRF check into a new shared module,
lib/csrf-origin.ts, rather than writing a third copy -- that route already
solves this exact problem (Sec-Fetch-Site, Origin, Referer, X-Forwarded-*
aware, fails closed with neither header present) for the general API
proxy. Both new routes now reject with the same csrf_origin_rejected/403
shape.

Existing route tests constructed requests with no Origin header at all
(synthetic same-origin-by-default test fixtures), which the new fail-closed
check correctly rejects -- added a same-origin Origin header to each
file's shared postRequest() helper to match what a real same-origin
browser request actually sends, plus explicit regression tests for the
cross-site-rejected and no-origin-rejected cases in both files.

Full frontend suite (463 tests), tsc --noEmit, and eslint on every touched
file all pass.

Fixed the CSRF finding on this PR (2516ced3): both /auth/password/login and /auth/password/signup accepted state-changing POST requests with no Origin/Referer validation. Both parse the body via request.json(), which per the Fetch API spec parses regardless of the declared Content-Type — so a cross-site attacker sending Content-Type: text/plain (a CORS-simple type, no preflight) with a JSON-shaped body still gets through, meaning the browser's own CORS preflight never actually protected these routes the way it looks like it should. For login this is login CSRF (attacker's credentials silently submitted, victim's browser ends up signed into the attacker's account); for signup it's account creation as a side effect of visiting a page.

Reused rather than reinvented: app/api/[...path]/route.ts already has a correct, tested sameOriginStateChangingRequest check (Sec-Fetch-Site + Origin + Referer + X-Forwarded-* aware, fails closed with neither header present) — extracted it into lib/csrf-origin.ts instead of writing a third copy, and both new routes now use it.

Existing route tests built requests with no Origin header at all; added a same-origin header to each file's shared postRequest() helper to match what a real same-origin browser request sends, plus explicit new tests for cross-site-rejected and no-origin-rejected. Full frontend suite (463 tests), tsc --noEmit, and eslint on every touched file all pass.

Still open on this PR, not addressed here: unbounded request bodies, noopener=false on the identity popup, long-name truncation, and the tab-closing logic bug — those are separate, unrelated findings.

In `@docs/adr/0005-naruon-owned-password-login-form.md`:
- Around line 65-84: Replace the Resource Owner Password Credentials flow used
by exchangePasswordForSessionResponse in
frontend/src/app/auth/password/login/route.ts:53 and
frontend/src/app/auth/password/signup/route.ts:110 with the Keyverse-supported
headless authentication or session contract, preserving Authorization Code with
PKCE for federated SSO. Update
docs/adr/0005-naruon-owned-password-login-form.md:65-84 to document the
replacement and remove the grant_type=password/direct-access-grants decision;
these three sites all require changes.

In `@docs/adr/README.md`:
- Line 16: Remove the Resource Owner Password Credentials flow from the login
and signup paths associated with ADR-0005, including both affected sections in
frontend/src/components/SettingsLayout.tsx at lines 614-623 and 645-654; replace
direct password submission using grant_type=password with Keyverse’s supported
headless authentication/session contract, and add regression tests that reject
any grant_type=password usage. The ADR README entry requires no direct change
beyond ensuring it is not accepted until these implementation and test changes
are complete.

In `@frontend/src/app/auth/callback/page.tsx`:
- Around line 16-38: Update the callback’s popup-mode detection in the useEffect
flow to rely on the explicit login-flow marker established by startOidcLogin,
rather than window.opener alone. Ensure blocked-popup redirects are treated as
normal-tab callbacks that execute window.location.replace(safeTarget), while
genuine popup flows retain postMessage and window.close behavior.

In `@frontend/src/app/auth/password/login/route.ts`:
- Line 40: Replace direct request.json() calls in the login route and signup
route with a shared bounded JSON reader that enforces the application-level body
limit before parsing, including declared and chunked payloads. Return HTTP 413
for oversized bodies while preserving the existing malformed-body response, and
add tests for both oversized-body cases before modifying production code.

In `@frontend/src/app/auth/password/signup/route.ts`:
- Around line 24-29: Update the signup route to return a validation response
when first_name or last_name exceeds MAX_NAME_LENGTH, rather than normalizing
the value to undefined and omitting it from registration; add the same
maximum-length constraint to the corresponding signup form fields.

In `@frontend/src/lib/account-unification-client.ts`:
- Around line 91-99: Update the fetch options in the password-registration
request to set redirect handling to error, preventing redirects from forwarding
the POST body to an unvalidated destination while preserving the existing
request behavior.

In `@frontend/src/lib/oidc-session.ts`:
- Line 165: Update the OIDC popup flow around window.open to remove the live
opener relationship instead of passing noopener=false, and replace
opener-dependent completion signaling with a nonce-bound same-origin channel
such as BroadcastChannel. Preserve the existing callback validation and ensure
the channel is uniquely associated with the login attempt and cleaned up after
completion.

Fresh lifecycle review on exact head 2516ced3cf4ee2aa81f6286f82f27821e1ac70db confirms this lane must remain Draft.

The blocking architecture finding is now stronger than the earlier local risk-acceptance framing. RFC 9700 §2.4 says ROPC MUST NOT be used; RFC 10017 §7.3 (August 2026 browser-app BCP) repeats that prohibition and requires a redirect-based OAuth/OIDC flow such as Authorization Code for conforming browser applications. A local ADR can record accepted risk, but it cannot turn grant_type=password into a standards-conformant mechanism. Canonical owner evidence was sent to ContextualWisdomLab/keyverse#128; Naruon must consume only a repaired immutable Keyverse contract.

Primary references:

Keep the product requirement unchanged: Naruon owns the login/signup/recovery forms and Keyverse remains the identity backend. Repair the mechanism, not the requirement. Until Keyverse publishes a standards-conformant headless auth/session contract, remove/withhold the ROPC login/signup runtime path rather than declaring ADR-0005 Accepted.

There are also multiple current-head unresolved review findings that independently prevent Ready status: popup opener/control and popup-mode correctness, delayed popup initialization, missing browser E2E, stale settings refresh after login, signup account-created/session-failed ambiguity, over-length name handling, bounded request-body handling, stable upstream error-code allowlisting, protected registration-secret storage, DNS-rebinding/address-pinning and redirect denial on password registration, and deployment wiring. Current exact-head hosted evidence is also non-GREEN: CodeQL run 33708243155 is startup_failure, while Application CI/Security/SAST/Dependency Review/Bandit/Docker/OSV/Scorecard are queued.

No predecessor review/check evidence transfers. Do not merge or mark Ready until these findings are repaired on a non-force successor, all live required checks are terminal-success on that exact head, review threads are resolved, and the live post-last-push approval requirement is satisfied.

Four independent CodeRabbit findings on the naruon-owned password
login/signup flow, triaged and handed off by the peer session owning
this PR:

- OIDC popup opened with noopener=false (CWE-1021): the cross-origin
  Keycloak authorization page could navigate the naruon tab via
  window.opener. Sever popup.opener = null immediately after opening;
  replace window.opener/postMessage entirely with a same-origin
  BroadcastChannel (which needs no opener relationship) for popup ->
  opener completion signalling.

- isLoginPopup() used window.opener as its only signal for "is this
  page running inside the popup" -- unreliable (any tab with some
  opener, for any reason, would be misidentified), and now moot once
  opener is severed anyway. Replaced with a per-attempt flowId encoded
  in the popup's own window.open() target name, read back via
  window.name -- self-contained per-window state, no shared-storage
  race between simultaneous login attempts in different tabs.

- Both password routes called request.json() with no body-size bound
  (CWE-400): a caller could force an oversized parse/allocation before
  any per-field validation ran. Added a shared bounded JSON reader
  (docs/auth/oidc/shared.ts) that checks Content-Length as a fast path
  and enforces the same cap while streaming the body, covering a lying
  or absent Content-Length (chunked transfer) too. Returns 413 for an
  oversized body via both routes.

- Signup silently dropped (not rejected) an over-length first/last
  name -- JSON.stringify omits an undefined field, so the account got
  created without it instead of the caller being told to fix it. Now
  rejected outright with a dedicated error code.

- account-unification-client.ts's password-registration fetch had no
  redirect handling; fetch's default follow behavior preserves the
  POST body across a 307/308, which would forward the plaintext
  password to whatever a misconfigured/compromised response's Location
  names. Added redirect: "error".

Two other findings triaged as already covered, not touched: the ROPC
grant itself (RFC 9700 tension) is a deliberate, product-owner-accepted
exception recorded in ADR-0005 + keyverse's ADR-0014, not an oversight.

All four verified against the actual current code before fixing (per
this repo's standing review-agent instruction to treat findings as
untrusted and verify against current code, not the finding text).
Full suite (472 tests, 54 files) + tsc --noEmit + eslint all pass.

…TERN

shared.ts's OIDC_CONTROL_CHARACTER_PATTERN regex contained a literal raw
NUL (0x00) and unit-separator (0x1f) byte at `[\x00-\x1f\x7f]`, in place
of the intended escape-sequence text. This predates ddeca08 (present
already at the base this branch built on) and is functionally equivalent
(the parsed regex still matches the same character range 0x00-0x1f, 0x7f),
but the raw NUL made git treat the whole file as binary -- Bin diffs
instead of line-level diffs -- degrading review for every change to this
file, in a security-sensitive OIDC/popup auth path where reviewability
matters most.

Replaced the raw bytes with the literal `\x00-\x1f\x7f` escape text.
472/472 tests, tsc, and eslint all clean.

…low-up

The signup route already rejects an over-length name outright (this
PR's earlier fix), but the form itself gave no client-side hint. Adds
maxLength={100} matching the route's own MAX_NAME_LENGTH -- immediate
feedback, not a substitute for the route's own validation, which still
rejects regardless of what the client enforces.

Note: the form only has a single "이름" (name) field bound to
first_name; there is no separate last-name input to also update.

Two independent bugs, both breaking CI on this PR's own diff:

- account-unification-client.ts declared its request options as
  node:http's RequestOptions, which doesn't include `servername` (a
  TLS/SNI option). The file's own sibling oidc-token-client.ts already
  gets this right by importing RequestOptions from node:https instead
  (a structural superset, since https.RequestOptions extends
  http.RequestOptions with the TLS options) -- matched that pattern.
  This broke `next build`'s type-check step ("validate frontend image").

- oidc-session.test.ts's new popup-broadcast test called
  broadcastOidcPopupResult() immediately after openPopup fired, but
  startOidcLogin only registers its BroadcastChannel listener (inside
  waitForPopupCompletion) after the async server round-trip completes.
  The broadcast raced ahead of the listener and was silently dropped
  every run, hanging until the 5s timeout ("frontend" test job).
  Waits for fakePopup.focus() -- the last synchronous call before the
  channel is created, with no await between them -- before broadcasting.

Verified: full frontend suite (478 tests), typecheck, lint, and
`next build --webpack` all pass together.

sourceFile("../../oidc/shared.ts") resolves against the test file's
own location (frontend/src/app/auth/password/), landing two levels up
at frontend/src/app/oidc/shared.ts -- which doesn't exist. The real
file is one level up, at frontend/src/app/auth/oidc/shared.ts. The
test threw ENOENT on every run since it was added in ff18d27,
silently failing the whole "does not retain dormant ROPC or
password-registration authority" assertion. CodeRabbit's own
verification never caught this because its checks are grep-based
(rg/sed over file contents), not an actual test run.

… of leaving them stale

Devin Review flagged (frontend/src/components/SettingsLayout.tsx:626,
2026-09-02): refreshOidcSessionClaims() only re-fetches identity after
login, not the other settings requests. If those fail while the user
is signed out (401, before Keyverse SSO completes), their error state
never clears without a full page reload -- even after a successful
login makes the same endpoints succeed.

Extracts the mount effect's runner-config/operational-signals/account-
config/calendar+webdav/llm-providers fetches into one loadAccountSettings
callback, still called once on mount, and now also called again after
handleOidcLogin's login succeeds. The synchronous "reset to loading"
setState calls stay out of the callback itself (calling setState
directly inside a useEffect body trips the set-state-in-effect lint
rule) and live in handleOidcLogin instead, which isn't an effect body.

Added a TDD-verified regression test: confirmed red against the
unfixed handler (the error text survives login), green against the
fix. Along the way, found the Korean fallback error strings throughout
this file's catch handlers (e.g. '계정 설정을 불러오지 못했습니다.')
are dead -- apiClient's thrown error always has a truthy .message
("API request failed"), so the `error.message || fallback` never
reaches the fallback. Left as-is; a real fix touches every catch
handler in this pattern and is out of scope for this change.
