A hijacked session must not be able to silently add a passkey as a
persistent backdoor or remove the victim's credentials. Registration
(begin) and deletion now verify the account password server-side,
reusing the existing PASSWORD_REQUIRED / PASSWORD_INCORRECT errors.
The password is used instead of TOTP step-up so the guard also protects
deployments that never configured a TOTP encryption key. The password
key in both request bodies is covered by the audit middleware's
key-substring redaction, so no credential material reaches audit_logs.
Frontend: the add-passkey form gains a current-password field, and the
delete confirmation is now a dialog with a password input (replacing
window.confirm), mirroring the TOTP disable dialog. Backend error
messages (e.g. wrong password) are surfaced instead of the generic
failure toast. Rename remains password-free as it is cosmetic.
When a /responses forwarding loop has attempted an OpenAI passthrough
account, sanitize every subsequent non-passthrough attempt by deriving its
body from the immutable canonical request and dropping provider-specific
encrypted reasoning input items in full.
This prevents Bedrock-compatible accounts from rejecting Kiro reasoning
IDs and encrypted_content, including on same-account retries and later
non-passthrough failovers. Preserve JSON numbers exactly while sanitizing.

PUT /api/v1/admin/settings is a whole-document write. The admin UI always sends
the complete document, so saving from the settings page is unaffected both
before and after this change. The bug is only reachable when an API client calls
the endpoint directly and sends just the fields it wants to change, which is the
natural assumption for a PUT on a settings resource.
Value-typed fields of UpdateSettingsRequest bind to their zero value when the
payload omits them, and buildSystemSettingsUpdates writes every key
unconditionally, so such a caller has no way to say "leave this one alone".
Omitting a field and explicitly clearing it are indistinguishable on the wire.
A caller that sends only the field it wants to change, e.g.
{"risk_control_enabled": true}
sets that flag and clears every other unguarded field in the same request.
Measured against a fully configured store, one such call empties site_name,
site_subtitle, api_base_url, contact_info and doc_url, and turns
registration_enabled, email_verify_enabled, invitation_code_enabled and
turnstile_enabled off. turnstile_enabled alone gates the captcha on login,
register, forgot-password and both verify-code endpoints, and
email_verify_enabled is a precondition of IsPasswordResetEnabled.
The damage is easy to miss. site_name has a built-in fallback, so
getStringOrDefault renders the cleared value as the default product name and the
login page visibly changes, while the toggles just go quiet. Reopening the
settings page reads the already-cleared state back into the form, so correcting
the one visible field and saving persists the rest of the damage.
Fields that grew their own guard already survive this: the SMTP block falls back
to the previous values when smtp_host arrives empty, secret fields are written
only when non-empty, and 132 request fields are pointers whose handler merges an
omitted field with the stored value. This generalizes that pattern rather than
adding a fourth ad-hoc guard.
The handler now decodes the payload a second time as a raw field map, resolves
the setting key each absent field would have written, and hands that set to the
service, which drops those keys before SetMultiple, so the stored value is never
touched. Fields the payload does carry are written as before, giving the caller
the partial-update semantics it was already assuming. The mapping is reflected off
the request's json tags so new fields are covered without maintaining a list;
smtp_from_email is the only field whose json name differs from its setting key
and is aliased explicitly.
Only value-typed fields are filtered. Pointer fields keep whole-document
behaviour on purpose: forwarded_client_ip_headers and
api_key_acl_trust_forwarded_ip depend on being rewritten on every save to
re-normalize fail-closed state, which the malformed forwarded-client-IP header
test pins down.
An explicitly sent empty value is still a deliberate clear; only absent fields
are preserved. A partial write refreshes the in-process caches from storage
instead of from the request struct, which holds zero values for whatever the
caller omitted.

Composite public aliases (e.g. all/claude) reach the Anthropic/Gemini
billing core via OriginalModel/ChannelMappedModel source overrides.
Unknown aliases resolved to no pricing and silently recorded $0 cost,
while family-word aliases were mispriced by the fallback family match
(Opus traffic billed at the Sonnet fallback rate). The OpenAI path
already guards this via usageBillingModelCandidates; the shared
recordUsageCore had neither the guard nor a fallback.
- composite groups: unless the admin explicitly configured channel
pricing for the alias (OpenRouter-style custom pricing), bill by the
concrete forwarded model
- general safety net: when the selected billing model has no resolvable
pricing at all, fall back to the concrete forwarded model instead of
silently recording $0
- grok media usage records now attribute OriginalModel to the client
requested public alias, consistent with every other endpoint
(billing unaffected: empty BillingModelSource never triggers source
overrides)
Priced traffic and non-composite groups are unaffected.
The composite-groups PR (#3581) replaced the raw ent SubscriptionPlan
response of GET /admin/payment/plans with a projection struct but
dropped the currency field added by #4323. PlanEditDialog then read an
undefined currency, sent an empty string on save, and silently wiped
the stored plan currency. Restore currency plus created_at/updated_at
so the projection preserves the full original response shape.
Persist reasoning ceilings and exact mappings for OpenAI groups, enforce them across HTTP and WebSocket forwarding, and invalidate cached auth snapshots.
