Products must render their own login, signup and recovery forms while Keyverse continues to verify credentials and issue tokens. This PR keeps the invalidated password mechanism disabled and records the concrete owner work still needed to deliver those forms. It remains Draft; the replacement ceremony is not implemented.

The retained implementation keeps Direct Access Grants off, rejects silent re-enablement in the realm validator, and returns HTTP 503 before the password-signup route creates an account. The shared runtime client no longer implements or allowlists password reset. Existing HTTPS transport validation and omitted-token revocation fixes are preserved.

The documentation follow-up corrects premature Accepted labels and renumbers this PR's two historical proposals from ADRs 0014/0015 to 0017/0018 because PR129 already reserves 0014–0016. ADR0019 proposes a Keyverse-owned Keycloak provider for product-rendered passkey ceremonies with native verifier reuse, origin/RP-ID migration, browser/session/client/PKCE binding, replay prevention, email verification, recovery assurance, realistic negative tests, and immutable release/rollback gates. These are proposed operations, not a released API. The separate PR129/PR130 numbering conflict remains for its owner to repair.

Current source and stack:

  • Head: f893ec6f5ecf1a324365b684505f8dff0cbc468c.
  • Base: PR146's codex/keyverse-orchestrator-free-development at e6da5dd3762b45acf4e0a70b672327f38f4ba04b.
  • Normal descendant of prior PR128 head e1cf0807d6b15e8d8300eb252533aa05b20b93c9; no history or predecessor delta was discarded.
  • Production application tree remains c1084571e48b450040090afa7c6052162ed4a9ef; this follow-up changes documentation only.

Validation: all 7 repository documentation tests passed on CI's Python 3.12, 26 local document links resolve, the three proposals are explicitly Proposed, and the diff check passed. No production code, workflow, runtime configuration or test gate changed. Earlier full-suite results remain historical; they are not presented as fresh hosted acceptance on this head.

The next owner implementation is a pinned-engine login start/complete experiment followed by signup and recovery, with an actual product-origin WebAuthn proof and normal authorization-code exchange. The research observed Keyverse 26.3.2 and a separate LineageWeave 26.0.8 engine without modifying either. No real-account authentication or deployment is claimed.

Keep this PR Draft until PR146 protected-merges, then restack normally onto current protected main. Complete the owner engine/schema/security/release evidence and consumer browser journeys before claiming authentication delivery. Independent approval and fresh exact-head required checks remain mandatory.

Primary standards: RFC9700 §2.4, RFC10017 §7.3. Detailed vendor/source and recovery references are recorded in docs/doctoring/2026-09-07-product-passkey-ceremonies.md.

naruon's product owner rejected a Keycloak-theme-reskin approach outright —
even a visually-identical theme is still Keycloak's server rendering the
page. The re-confirmed requirement is naruon's own frontend rendering 100%
of the login form with zero Keycloak-rendered HTML, backed by naruon's own
server calling Keyverse purely as an API.

WebAuthn login as a headless API was investigated and ruled out: Keycloak's
authentication ceremony (unlike registration) runs inside its own
login-actions flow bound to a server-side AuthenticationSessionModel, with
no public REST pair for the ceremony itself. Direct Access Grants (ROPC) is
the only Keycloak-native mechanism that fits the zero-Keycloak-HTML
requirement, so this flips `directAccessGrantsEnabled: true` for
`naruon-web` only — a scoped, reviewed exception to ADR-0002's
passwordless-first default, recorded in ADR-0014. Every other/future RP
remains hard-blocked by account-unification's dynamic-registration
validator (`directAccessGrantsEnabled` must be false).

This does not make login functional yet: no account in the `cwl` realm has
a password credential today (registration explicitly refuses to create
one), so every Direct Access Grants attempt still fails closed. A
credential-issuance path is flagged as separately-reviewable follow-up
work, not implemented here.

…gnup

ADR-0014 enabled Direct Access Grants for naruon-web but left login
non-functional: no account in the cwl realm has a password credential,
since POST /registration/accounts deliberately never creates one. This
closes that gap with the minimum reviewable change, recorded in
ADR-0015.

Adds POST /registration/accounts/password (app/password_registration.py),
mirroring POST /registration/accounts' shape (rate limiting, email
validation, create-then-rollback) but ending in an immediately usable,
non-temporary password credential via a new ProductAdminApi.reset_password
method. Gated by a third, independent bearer token
(password_registration_api_token) that account-unification's config loader
requires to differ from both operator_api_token and registration_api_token
— naruon is the only intended holder. The new Admin REST path is added to
the existing allow-list (_ADMIN_PATH_PATTERNS) rather than opening a new
credential surface.

The account-unification dynamic-RP-registration validator is unchanged:
it still hard-rejects directAccessGrantsEnabled=true for every RP except
the hand-authored naruon-web client, so this exception stays scoped to
naruon exactly as ADR-0014 established.

Also adds a realm-level passwordPolicy (length(12) and notUsername and
notEmail) as a second, server-side enforcement layer independent of the
endpoint's own validation, and a --password-registration-token flag to
tools/seed_config_store.py for local bring-up.

Explicitly deferred (see ADR-0015): email verification, CAPTCHA-equivalent
abuse hardening beyond the existing per-peer rate limit, self-service
password reset, and merging password/passwordless identities for the same
person.

seonghobae added a commit to ContextualWisdomLab/naruon that referenced this pull request Sep 2, 2026
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 — current-source / standards mismatch on exact head 5661b3d7c1d4bc4505b455086d2feafba4d832d9.

This PR deliberately enables directAccessGrantsEnabled: true for naruon-web and ADR-0014 treats OAuth 2.0 ROPC as the accepted API-only mechanism. That conclusion is not compatible with the current OAuth security BCP: RFC 9700 §2.4 says the Resource Owner Password Credentials grant MUST NOT be used, because it exposes the resource-owner credential to the client, expands credential-leak surface, and cannot support modern multi-step/WebAuthn authentication. The PR's references stop at RFC 6749 (2012), so the architecture decision omits the current normative security guidance.

RED acceptance: add an executable architecture/security regression that fails this candidate when any production naruon-web configuration enables Direct Access Grants or a production auth adapter submits grant_type=password; require the ADR/reference ledger to include RFC 9700 and classify ROPC as prohibited rather than a scoped normal exception.

GREEN acceptance: make an explicit product/security choice and prove it at the production boundary: (A) retain Authorization Code + PKCE with authentication handled by Keyverse/Keycloak so the OAuth client never receives the user's password, or (B) separately design/review a genuine first-party Keyverse authentication ceremony/API (e.g. an origin-bound WebAuthn provider) and then use a non-ROPC OAuth/OIDC flow. Do not satisfy this by renaming or wrapping grant_type=password behind another endpoint. Preserve fail-closed behavior, rate limits, replay protection, MFA/step-up capability, the passwordless direction, and fresh exact-head 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

Current exact-head checks are still queued/non-terminal, so they are not passing evidence. Do not merge this head until the security/product decision and RED→GREEN repair are resolved.

Naruon consumer review found that this canonical-owner exception must not merge in its current form.

keyverse#128@5661b3d7c1d4bc4505b455086d2feafba4d832d9 explicitly enables Keycloak Direct Access Grants / OAuth Resource Owner Password Credentials for naruon-web and adds password issuance so the consumer can submit grant_type=password. Current primary guidance is normative: RFC 9700 §2.4 states that the Resource Owner Password Credentials grant MUST NOT be used because it exposes user credentials to the client, expands credential-compromise surface, and does not fit MFA/WebAuthn/multi-step authentication. Keycloak's current OIDC documentation repeats that prohibition and recommends Authorization Code or Device Authorization; the March 2026 OAuth 2.1 draft omits ROPC entirely.

The consumer product requirement is not being withdrawn: Naruon owns its login/signup/recovery forms and Keyverse remains the identity backend. Please repair the owner contract rather than relaxing the UI requirement or turning Naruon into an OAuth-password client. A suitable owner solution should expose a supported, versioned headless authentication/session boundary for the Naruon origin—preferably passkey/WebAuthn + recovery/session semantics or another standards-compliant first-party contract—while federated/SSO can continue through Authorization Code + PKCE where authorization-server browser interaction is appropriate. Do not require Naruon to receive Keycloak admin credentials or reproduce Keyverse authentication policy.

Owner RED/GREEN should reject directAccessGrantsEnabled=true / grant_type=password for Naruon too, prove phishing/credential-handling, MFA/passkey, recovery, replay/session, rate-limit and anti-enumeration behavior at the Keyverse boundary, and publish the resulting contract immutably before the Naruon consumer bump. ADR-0014/0015 and SECURITY/THREAT_MODEL/TRACEABILITY should cite RFC 9700 §2.4 and current Keycloak guidance and supersede the present claim that ROPC is the acceptable/only native mechanism.

No Keyverse source was modified by the Naruon writer; this is the exact canonical owner path handoff.

New accounts created via /registration/accounts/password inherited the
realm's default required action (WebAuthn passwordless enrollment) because
_to_keycloak_user never set requiredActions in the Keycloak create-user
payload. That default is an interactive browser step Direct Access Grants
cannot complete, so every immediate post-signup login failed even though
the account already has a usable password credential -- confirmed
independently by Devin Review on both this PR and naruon#1532's paired
frontend PR.

UserAccount gains an optional required_actions field (None preserves the
existing realm-default behavior for every other caller, e.g. the
passwordless registration flow, which still wants that action).
register_account_with_password now passes required_actions=[] explicitly.

Pushed a root-cause fix for the Devin finding "New password accounts cannot log in" (BUG_pr-review-job-29f2be955ed14524b7487101aea0ae2c_0001, password_registration.py:151-160): 7c1939d.

Root cause: _to_keycloak_user never set requiredActions in the Keycloak create-user payload, so every new account (including ones created through this endpoint) inherited the realm's default required action (WebAuthn passwordless enrollment). That's an interactive browser step Direct Access Grants can't complete, so the immediate post-signup login this endpoint's own docstring promises ("a Direct Access Grants login right after signup succeeds") never actually worked.

Fix: UserAccount gets an optional required_actions field (None preserves the existing realm-default behavior for every other caller, notably the passwordless /registration/accounts flow, which still wants that action). register_account_with_password now passes required_actions=[] explicitly. New tests cover _to_keycloak_user's three states directly (test_keycloak_client.py) and assert the end-to-end registration response has no required action (test_password_registration.py). Full suite + coverage + interrogate + ruff all pass locally on the touched files (100% test/docstring coverage, no lint findings).

This is also the same bug Devin flagged independently on the paired naruon PR (naruon#1532, "Created accounts appear to fail") — that PR's own post-signup login attempt was hitting this exact failure.

Have not yet addressed the other findings on this PR (existing-deployment grant reconciliation, unverified-signup member access, rate-limit bypass on malformed bodies/proxy traffic, rate-limit-state cleanup, seed-token staleness) — picking those up next rather than bundling everything into one commit.

Traced the two 🔴 Devin findings ("Existing deployments retain disabled grants," "Reconciliation disables Naruon grants") to their actual root cause — this one I'm flagging rather than fixing, because it runs into ADR-0014's own explicit, reasoned decision and I don't think an agent should silently reinterpret that.

The contradiction, with exact evidence:

  • docs/adr/0014-naruon-owned-password-form.md §Decision point 3: "The account-unification service's dynamic RP registration validator is not changed... naruon-web is a hand-authored client in the portable realm, not a dynamically-registered one, and this ADR does not extend the exception to any other or future RP." services/account_unification/app/relying_party.py:534-535 still unconditionally does if registration.direct_access_grants_enabled: _client_error(...) for every client — matches the ADR, by design.
  • But deploy/templates/oidc-rp-naruon.json (added by feat(clients): add a closed OIDC RP claim mapper profile #72, before ADR-0014 existed) already routes naruon-web through exactly the dynamically-registered pipeline the ADR says it isn't: deploy/templates/README.md documents it as Keyverse RP desired-state API with apply endpoint PUT /clients/relying-parties/naruon-web, and docs/operations/oidc-rp-reconciliation.md is a live, actively-documented runbook (not dead code) whose step 4 is "Call PUT /clients/relying-parties/{client_id} with the same original file" — i.e. a full-replace apply, not a partial patch.
  • That template's directAccessGrantsEnabled is false (line 10) — it has to be, or POST /clients/relying-parties:validate (runbook step 3) would reject it outright given the validator above. So the documented, sanctioned way to reconcile naruon-web's redirect URIs or claim mappers (a real, ongoing operational need — see the "Naruon mapper contract" section of the same runbook) silently reverts directAccessGrantsEnabled to false as a side effect, undoing this PR's exception the next time anyone follows that runbook.

Why I'm not just fixing this: the two consistent resolutions I can see are (a) retire oidc-rp-naruon.json + its runbook/README rows for naruon-web specifically, so it's genuinely hand-authored end-to-end as the ADR describes, and find another sanctioned path for its legitimate redirect-URI/mapper updates; or (b) add a narrow, client_id == "naruon-web"-gated exception to validate_relying_party_registration after all, and amend ADR-0014 to record that reversal with its own reasoning. Both are real architecture decisions the ADR's author(s) explicitly weighed once already (point 3's reasoning reads as deliberate, not an oversight) — I don't think it's my call to quietly pick one without whoever owns that ADR weighing in on whether the newly-found contradiction changes their reasoning.

Separately fixed and pushed in 7c1939d (see earlier comment): the "new password accounts cannot log in" bug. Still open, not yet touched: unverified-signup member access, rate-limit bypass on malformed bodies/proxy traffic, rate-limit-state cleanup, seed-token staleness, the missing CHANGELOG/ops-doc entries CodeRabbit flagged.

Checked the remaining findings against docs/adr/0015-naruon-password-credential-issuance.md's own "Deferred (not shipped in this slice)" section before touching anything else, and most of them turn out to already be known, reviewed tradeoffs rather than fresh bugs:

  • "Unverified signups receive member access" — ADR-0015 "Deferred" §1 explicitly: "Accounts are created with emailVerified: false and no VERIFY_EMAIL required action, so an unverified, even non-existent, address can be signed up and immediately used. A follow-up should send a verification link post-signup..." Documented, not overlooked.
  • "Proxy traffic shares one signup quota" / "Malformed signups bypass throttling" / rate-limit-state cleanup — all sub-cases of ADR-0015's explicitly-accepted §"Abuse/rate-limiting surface": "materially weaker abuse posture than POST /registration/accounts... Explicitly accepted as this slice's tradeoff, not overlooked."
  • "Seed reruns preserve old signup access" — haven't traced this one against the ADR yet, still open.
  • "Registration secret bypasses protected storage" — the ADR's own security section does discuss this token's blast radius (bounded by _ADMIN_PATH_PATTERNS) but doesn't address storage-at-rest; this reads as a broader org-wide "no vault yet" gap rather than something specific to this PR, still open.

So: the login-blocking bug (fixed in 7c1939d) was the one place this PR's actual behavior contradicted its own ADR's stated guarantee ("this flow's account works immediately on creation" — it didn't). The reconciliation/validator conflict (previous comment) is a real, separate architecture question for whoever owns ADR-0014 to weigh in on. Everything else Devin/CodeRabbit flagged beyond those two is either an already-reviewed, ADR-recorded deferral, or still genuinely open (seed-token staleness, storage-at-rest for the bearer token) — leaving those for a follow-up pass rather than re-deciding already-decided tradeoffs under time pressure.

Current-head architecture/security finding on 7c1939d9ed28f70aa38eaf5f7e830284efce7a95: this PR cannot be treated as release/merge-ready while it makes Resource Owner Password Credentials / Keycloak Direct Access Grants the production authentication path.

The governing standard has moved past a discretionary trade-off. OAuth 2.0 Security Best Current Practice, RFC 9700 §2.4, says the Resource Owner Password Credentials grant MUST NOT be used. The current OAuth 2.1 draft omits the grant for that reason, and current Keycloak documentation repeats the RFC 9700 prohibition and lists the resulting credential exposure / MFA / brokering limitations. Primary references: https://www.rfc-editor.org/rfc/rfc9700.html#section-2.4 , https://datatracker.ietf.org/doc/draft-ietf-oauth-v2-1/ , https://www.keycloak.org/securing-apps/oidc-layers#_resource_owner_password_credentials

This also conflicts with Keyverse's canonical passwordless/OAuth2.1 direction documented in this PR itself. A scoped client exception and a third bearer token do not remove the protocol-level problem; they add another privileged credential and make Naruon handle the resource owner's password.

RED acceptance: keep a contract test proving naruon-web.directAccessGrantsEnabled remains false and that no grant_type=password consumer contract is released. Add a failing headless-login contract that expresses the actual product requirement: Naruon renders its own login/signup/recovery forms while Keyverse owns credential verification/session/token issuance, with no Keycloak-rendered page and without ROPC.

GREEN acceptance: implement that requirement behind a Keyverse-owned, versioned headless authentication boundary (for example, a separately scoped Keyverse/Keycloak extension or service that performs the supported passwordless/WebAuthn ceremony and returns an authorization result/token through an OAuth 2.1-compatible flow), with replay/challenge/session binding, phishing-resistant WebAuthn evidence, recovery policy, rate limiting, audit, and E2E tests. Then remove the directAccessGrantsEnabled=true, password-registration ROPC dependency, and the two ADRs' Accepted status; replace them with a Proposed/Superseded decision record that cites RFC 9700 and the released headless contract. Naruon should consume only that released API/contract.

I attempted to move the PR back to Draft, but GitHub GraphQL is currently rate-limited; no PR-state transition occurred. Treat this comment as the exact-head repair finding, not as approval.

Naruon consumer-side fresh standards validation found that this owner PR cannot be treated as a releasable authentication contract in its current ROPC form.

RFC 9700 §2.4 (BCP 240, January 2025) states that the Resource Owner Password Credentials grant MUST NOT be used. RFC 10017 §7.3 (OAuth 2.0 for Browser-Based Applications, BCP, August 2026) repeats that prohibition and requires browser-based OAuth/OIDC applications to use a redirect-based flow such as Authorization Code. A product-owner risk acceptance can document a deviation, but it cannot make grant_type=password standards-compliant.

Primary references:

Naruon #1532 has therefore been returned to Draft rather than consuming this mutable/unreleased path. Please keep the valid product intent—Naruon-owned login/signup/recovery UI with Keyverse as the canonical identity backend—but repair the canonical Keyverse boundary instead of landing Direct Access Grants. The owner-side target should be a versioned headless authentication/session contract that can support modern multi-step/passwordless authentication (including passkey/WebAuthn where applicable), with recovery/verification/abuse controls and without directAccessGrantsEnabled or a raw password grant. Existing Authorization Code + PKCE remains appropriate for federated SSO. Publish the repaired contract immutably before Naruon consumer pinning.

Do not close this PR merely because the current mechanism is invalid: the headless-auth product delta is still valid and needs repair/successor preservation.

…finding

RFC 9700 §2.4 (BCP 240, Jan 2025) states the Resource Owner Password
Credentials grant MUST NOT be used; RFC 10017 §7.3 (OAuth 2.0 for
Browser-Based Applications, BCP, Aug 2026) independently repeats that
prohibition for browser-based apps specifically. Neither RFC existed
when this ADR was accepted, and the product-owner risk acceptance it
relies on (satisfying ADR-0002's amendment clause) cannot make
grant_type=password standards-compliant -- these are current IETF
security guidance, not a local preference a risk memo can override.

Discovered when naruon#1532 (the companion PR implementing this ADR's
point 4) was returned to Draft over this exact finding rather than
merged. Adds a Correction section documenting the finding in full,
with citations, while explicitly preserving the ADR's still-valid
Context and ruled-out-alternatives sections -- the product requirement
(naruon-owned login UI, Keyverse as backend, zero Keycloak-rendered
HTML) is not in question, only the ROPC mechanism needs a successor.
Status intentionally left Accepted, not Rejected, per this org's
repair-not-close convention for findings against an already-accepted
decision with real, still-valid product intent behind it.

…string

The one-line docstring ("Validate one client registration without
persistence or network access.") didn't meet this org's own standing
requirement (docs/product-goal-directive.md: docstrings must be
sufficient for a beginner to understand without separate code
analysis) -- a reader had to trace every _client_error() call to
learn what the function actually enforces and why, including the
non-obvious RFC 9700/10017 reasoning behind rejecting
directAccessGrantsEnabled that this same PR just added to ADR-0014.

Expands the docstring to name every enforced property of the fixed
client-security profile (client-id/name identity, enabled+OIDC only,
authenticator type matching client type, Authorization Code only
with implicit/ROPC/service-accounts/full-scope all rejected and why,
redirect/web-origin/logout-URI consistency), and what it raises vs.
returns. No behavior change -- docstring only, verified via ast.parse.

Devin review on #128 found the ADR's own Correction (2026-09-03) rejects
grant_type=password (RFC 9700 SS2.4 / RFC 10017 SS7.3), but two artifacts
still approved the invalidated mechanism: the ADR index (docs/adr/README.md)
still showed a bare "Accepted" with no caveat, and naruon-web's
directAccessGrantsEnabled stayed true in the committed realm export.

Set the flag back to false as a fail-closed measure -- this PR is unmerged
and nothing live depended on it staying true -- and updated the ADR index
and deploy/keycloak/README.md to match the ADR's own status line. ADR-0014's
Decision section is left unedited as the historical record of what was
originally decided, per this repo's repair-not-rewrite-history convention;
a new note in the Correction section points out it no longer matches the
live config value.

No test asserts naruon-web's directAccessGrantsEnabled must be true;
services/account_unification/tests/test_realm_policy.py and
scripts/validate_realm.py both pass unchanged.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Devin's follow-up review on #128 (after 79fe43d disabled directAccessGrants)
found the actual cascading bug: POST /registration/accounts/password still
created password-only accounts with required_actions=[], but with ROPC
disabled there is no way to log into them -- the bound browser-passwordless
flow accepts only passkeys. Confirmed by reading the endpoint directly: its
own docstring said "so a Direct Access Grants login right after signup
succeeds", which is no longer true.

Fixed by gating the endpoint behind a module constant
(PASSWORD_CREDENTIAL_LOGIN_AVAILABLE = False), mirroring the same
fail-closed pattern used for the realm flag -- a single flippable point,
not a rewrite of the account-creation/rollback/rate-limit logic
underneath, which stays intact and fully covered via monkeypatch-enabled
tests for whenever a standards-compliant replacement ships. Added
test_registration_fails_closed_by_default for the new default branch.

Also addressed two more Devin findings on the same review pass:
- scripts/validate_realm.py never asserted directAccessGrantsEnabled must
  stay false for naruon-web, so a later realm edit could silently restore
  the blocked grant while CI still passed. Added the check
  (test_naruon_direct_access_grants_stays_disabled covers it).
- ADR-0015 and its docs/adr/README.md index row still promised immediate
  Direct Access Grants login. Added a Correction section mirroring
  ADR-0014's, status line updated to match.

Verified: services/account_unification full suite (100% pass), coverage
--branch --source=app --fail-under=100 (100%), interrogate (100%), ruff
(clean), scripts/validate_realm.py, make test, make validate-realm,
tests/test_documentation_contract.py -- all pass.

…ing record

Devin's third review pass on #128 found two more real gaps: the generated
OpenAPI docs for POST /registration/accounts/password still promised 201
account creation with no mention it now always returns 503, and disabling
the endpoint had no CHANGELOG entry, operations runbook note, or APA 7th
doctoring record -- required by this repo's own documentation-traceability
convention.

Fixed:
- password_registration.py: added a `responses={503: {...}}` entry to the
  route decorator so the generated OpenAPI schema documents the current
  fail-closed behavior (confirmed via app.openapi() that '503' now appears
  alongside '201'/'422').
- CHANGELOG.md: new Fixed entry summarizing the two-pass ROPC correction.
- docs/OPERABILITY.md: new "naruon password-signup 503 (expected, not an
  incident)" runbook section so on-call doesn't treat the deliberate 503 as
  a live-dependency failure.
- docs/doctoring/2026-09-03-naruon-password-ropc-standards-correction.md:
  new record following this repo's established doctoring format (Scope /
  Interpretation / Evidence / References), covering both fix passes.
- ADR-0014 and ADR-0015: added formal APA 7th References entries for RFC
  9700 and RFC 10017 (previously only cited inline in the Correction prose).
  Cited by issuing organization rather than named individual editors --
  RFC 10017 is dated after any available verification cutoff, so inventing
  an author list for it (or asserting unverified authors for RFC 9700)
  would risk misattribution; a note says to confirm editors directly from
  the RFC Editor page before citing either with named authors elsewhere.

Verified: full test suite, coverage --branch --source=app --fail-under=100
(100%), interrogate (100%), ruff (clean), tests/test_documentation_contract.py,
and a direct app.openapi() check confirming the 503 response is documented.

Devin's review on #128 (third pass) found that PASSWORD_CREDENTIAL_LOGIN_AVAILABLE
blocks every request to the endpoint that used to call ProductAdminApi.reset_password,
but the shared admin client's capability to call Keycloak's reset-password endpoint
is unaffected -- an unused-but-present authority surface on a client used broadly
across the whole account_unification service.

Not removing the method or its _ADMIN_PATH_PATTERNS entry outright: doing so
would need either verifying no other current or near-term caller needs it, or
accepting the endpoint can never be re-enabled without restoring it -- neither
verified in this pass. Documented it as dormant instead, on both the Protocol
declaration and the HttpAdminApi implementation, pointing at ADR-0014's
Correction and this finding, so it gets re-scoped deliberately alongside
whatever replacement login mechanism lands rather than assumed still
load-bearing.
