fix(voice): classify hosted live-voice billing refusals instead of reporting them - #8520
Hosted live-voice refusals for billing (Gemini live/sessions 400 USER_INSUFFICIENT_CREDITS, voice-agent signed-url 403 "paid plan" / "Insufficient balance") are now classified as user state instead of reported to Sentry.
The user sees "insufficient credits" / "paid plan required" in the live voice controls instead of a raw HTTP error.
Non-2xx backend failures now carry the backend errorCode (warn-logged) so classification does not depend on message text alone.
Both are expected account states, confirmed against the backend source (see FINDINGS-gemini-live.md, FINDINGS-voice-signed-url.md).
Solution
client/error.rs: new InsufficientCredits / PaidPlanRequired variants, flattened with INSUFFICIENT_CREDITS: / PAID_PLAN_REQUIRED: sentinel prefixes.
client/classify.rs: backend_billing_refusal maps errorCode USER_INSUFFICIENT_CREDITS, or a 403 whose error names a paid plan or budget, to those variants (info-logged, not reported). 401 handling and the existing budget filter run first and are unchanged.
observability_availability.rs / expected_error_classification: the sentinels demote to BudgetExhausted, so the RPC-boundary re-report is quiet too.
voice/live.rs: mint_error maps the sentinels to insufficient_credits / paid_plan_requiredLiveVoiceError codes; LiveVoiceControls.tsx renders them with new i18n keys (all 16 locales).
Submission Checklist
Tests added or updated: classifier unit tests with the real 182-byte reserve body, an axum round-trip test, mint_error test, demotion tests, LiveVoiceControls error-text cases
Diff coverage ≥ 80%: not measured locally (see Validation Blocked); CI will report
Follow-up PR(s)/TODOs: hosted voice ElevenLabs errors in a separate PR (fix/voice-provider-error-handling); backend side tinyhumansai/backend#1438. Both touch crates/openhuman-embed/src/host_internals.rs (one re-export line each), so the second to merge needs a trivial rebase.

error:cargo check fails on a clean upstream/main too (~400 errors: vendored submodule pins older than the host API, e.g. tinychannels_bus::module_progressive::ChannelOutputEvent); pnpm not installed
Live voice setup now shows clear messages when credits are insufficient or a paid plan is required, instead of a generic error. These billing-related errors are also handled consistently across supported voice services.
Localization
Added translated messages for insufficient credits and paid-plan requirements in supported languages, so users can understand why live voice setup was declined.
…kend failures
Diagnoses gemini live/sessions 400 (tinyhumansai#8501): Sentry only carried the body
shape. Append a safe, identifier-like errorCode to the report and add an
opt-in (OPENHUMAN_LOG_BACKEND_ERROR_TEXT) debug log of error/details text.
Client request unchanged; root cause is likely server-side (see
FINDINGS-gemini-live.md).

Complements the errorCode/opt-in error-text diagnostics from the previous
commit: also emit a warn line carrying only the identifier-shaped errorCode
(no raw body), and add a test for non-identifier / non-string codes.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Live voice first shipped in v0.64.14 (2026-10-08), so the gemini 400 is a
launch-day rejection, not a regression; the leading suspect is the tool
declarations in the ticket body. The signed-url 403 coincides with the new
elevenlabs-hosted provider, which is offered without an entitlement check.

…porting them
The backend refuses a Gemini Live session with a 400
`USER_INSUFFICIENT_CREDITS` when the balance is below the per-session reserve
(TAURI-RUST-13BR), and the voice-agent signed URL with a 403 "requires a paid
plan" / "Insufficient balance ... Add credits" (TAURI-RUST-11G3). Neither
matched the 400-only budget phrase filter, so both paged Sentry and the UI
showed the raw backend line.
authed_json now reads the errorCode and the 403 billing messages, logs them
at info, and returns typed InsufficientCredits / PaidPlanRequired errors that
flatten onto new INSUFFICIENT_CREDITS: / PAID_PLAN_REQUIRED: sentinels, which
expected_error_kind demotes. The hosted live providers map them to the
insufficient_credits / paid_plan_required session codes, and the live voice
controls show translated "add credits" / "paid plan" messages.

Walkthrough
The client classifies hosted billing refusals as typed errors, passes them through Gemini and ElevenLabs live voice handling, and displays localized messages for insufficient credits and paid-plan requirements. Tests cover classification, mapping, and error display.
Changes: Hosted billing refusals
Layer / File(s)
Summary
Classify transport billing refusals crates/openhuman-tinyhumans/src/transport/{port.rs,error.rs,mod.rs}, crates/openhuman-tinyhumans/src/client/backend_client_tests.rs, crates/openhuman-tinyhumans/src/transport/README.md
The transport classifies matching responses as insufficient-credit or paid-plan refusals and stores the refusal, status, and response body in a typed error. Tests cover matching and non-matching responses.
The authenticated client maps billing refusals to typed errors and adds validated backend error codes to reportable warnings. Sentinel prefixes identify billing refusals for observability classification. Tests and the findings document record the behavior, investigation, and verification status.
Map and display voice billing errors crates/openhuman-tinyhumans/src/voice/{live.rs,live_tests.rs}, app/src/features/human/LiveVoiceControls{.tsx,.test.tsx}, app/src/lib/i18n/*.ts, FINDINGS-voice-signed-url.md
Gemini and ElevenLabs mint failures map to dedicated billing error codes or a generic backend error. Live voice controls display translated messages. Tests cover the mappings and messages; locale files add translations. The findings document records the signed-URL investigation and verification status.
Epic: Shrink the core crate #7390: The PR changes the classifier surface for hosted billing refusals, but does not implement the proposed neutral Sentry filter and classifier-registry relocation.

Full details: Title check
Explanation
The title names the main change: hosted live-voice billing refusals are classified as user state instead of being reported to Sentry. The raw summary and PR objectives confirm this. The change covers Gemini live-session 400 responses with USER_INSUFFICIENT_CREDITS and voice-agent signed-URL 403 responses for paid-plan or balance requirements. The title is 81 characters and one sentence, so it meets the length and clarity guidance.
Full details: Linked Issues check
Explanation
The PR meets both active linked issues. For #8501, transport::billing_refusal recognizes USER_INSUFFICIENT_CREDITS on non-401 responses. finish_authed_json returns HostedApiError::InsufficientCredits, and mint_error maps it to insufficient_credits. For #8504, the same classifier recognizes qualifying 403 error text for a paid plan or exhausted balance. The client maps these cases to typed errors without Sentry reporting. LiveVoiceControls.tsx and locale files provide the user-facing messages. Tests cover classification, transport round trips, error mapping, demotion, and UI output.
Full details: Out of Scope Changes check
Explanation
The changes stay within the linked issue scope. Transport typing and validated errorCode logging support reliable classification of the reported backend failures. Observability demotion prevents duplicate reporting. mint_error, UI messages, locale entries, and tests implement the required user-state behavior. The findings documents record evidence for these changes. No unrelated product-area change is established.
Full details: Docstring Coverage
Explanation
Docstring coverage is 64.29% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 14 functions across 24 files. (1 skipped: 1 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

- Around line 300-302: Update the billing-refusal classification around
`backend_billing_refusal` so an explicit `USER_INSUFFICIENT_CREDITS` code is
classified before `is_budget_exhausted` can suppress it. Preserve the broad
budget-text check for responses without that explicit billing code.

…ver budget text
A 400 carrying errorCode USER_INSUFFICIENT_CREDITS whose message also matched a
budget phrase took the generic budget path, so live voice showed the raw backend
error instead of the credits message. Classify billing refusals first; budget
400s without the code are unchanged.

Review follow-ups on tinyhumansai#8520:
- What a backend response means is decided in the transport
(AGENTS.md hosted boundary). Move the billing-refusal classifier from
client/classify.rs into transport/error.rs: map_sdk_error now yields a
typed BackendTransportError::BillingRefusal, and BackendClient only
recovers it onto HostedApiError::{InsufficientCredits,PaidPlanRequired}.
IntegrationClient no longer reports the same envelope as a generic
non-2xx. A 401 keeps precedence as a credential failure.
- Remove the OPENHUMAN_LOG_BACKEND_ERROR_TEXT opt-in debug log: the
backend's error/details are free text that may echo user content. The
identifier-shaped errorCode stays in the warn line.
