fix(observability): classify DeepSeek 'Insufficient Balance' 402 as user-state (Sentry TAURI-RUST-4ZF)#2809
Conversation
…ser-state (Sentry TAURI-RUST-4ZF)
Add `"insufficient balance"` to the `is_provider_config_rejection_message`
PHRASES array. A user's custom BYO-key DeepSeek provider returns HTTP 402
`{"error":{"message":"… Insufficient Balance …"}}` when their DeepSeek
account balance is exhausted. Pure user-billing state — the remediation
is "top up the DeepSeek account", which Sentry has no way to act on.
This is the same class as the OpenRouter S5 "requires more credits" 402
already in the list — different upstream, different wire token. The
OpenHuman backend's own balance gate is handled separately by
`is_budget_exhausted_message` (different body shape), so there's no
backend false-positive risk: "Insufficient Balance" is a
DeepSeek-specific token our backend never emits.
Tests:
- `detects_insufficient_balance_402_family` — verbatim TAURI-RUST-4ZF
wire shape (issue 5679, model=ds/deepseek-v4-flash) + bare envelope.
- Existing `ignores_transient_and_server_and_unrelated` still green —
`"insufficient budget — add credits"` ("budget" ≠ "balance") and the
other negatives stay unclassified.

PR tinyhumansai#2796 (Sentry TAURI-RUST-35 family, "does not support tools") also
appends to this PHRASES array but at a different position (end of list
vs. next to the S5 entry) — no merge conflict expected.
## Test plan
- [x] `cargo test detects_insufficient_balance_402_family` — passes
- [x] `cargo test config_rejection` — 7 tests pass, 0 regressions
- [x] `cargo check --bin openhuman-core` — passes
- [x] `cargo fmt --check` — clean

Clean fix. The "insufficient balance" phrase sits correctly next to the OpenRouter S5 entry — same class of user-billing 402, just a different upstream token. Case-insensitive lowercasing is already in place so capitalisation variants are covered without any extra work.
Two things I verified:
-
False-positive risk — the PR's claim that the backend never emits this token holds.
is_budget_exhausted_messagehandles our own balance gate with a different body shape, so there's no path where our own error gets misclassified as a provider config rejection. -
Test coverage —
detects_insufficient_balance_402_familycovers both the verbatim Sentry wire body (nested escaping and all) and the bare upstream envelope. The existing negative case"insufficient budget — add credits"confirms the phrase doesn't over-reach. That's the right set of cases.
Approved.

Doc-comment claim "the OpenHuman backend balance gate is handled separately by is_budget_exhausted_message, which never emits this DeepSeek-specific token" is misleading — is_budget_exhausted_message (billing_error.rs:13) also matches "insufficient balance". The two classifiers share this token.
Dispatcher precedence in core/observability.rs::expected_error_kind:
- L199:
is_provider_config_rejection_message→ProviderConfigRejection← runs first, catches this now - L205:
is_budget_exhausted_message→BudgetExhausted← previously caught it
Any message containing "insufficient balance" reaching the central dispatcher (agent.run_single / web_channel.run_chat_task re-reports) now classifies as ProviderConfigRejection instead of BudgetExhausted. Backend-direct path (api/rest.rs:582) unaffected — it calls is_budget_exhausted_message independently before expected_error_kind.
Net behavioural impact: both demote to tracing::info! and suppress Sentry, so no event-volume regression. Only observable change is the telemetry kind tag flipping from "budget" to "provider_config_rejection" for the re-reported backend case. Silent shift for any downstream consumer that filters/dashboards on kind.
Requested change — rewrite the doc-comment to acknowledge the overlap + pin the precedence claim:
// TAURI-RUST-4ZF — DeepSeek (custom BYO-key) 402 when the user's
// DeepSeek account balance is exhausted. Body carries the upstream
// `{"error":{"message":"Insufficient Balance",...}}` envelope.
// NOTE: `is_budget_exhausted_message` also matches this token, but
// the `expected_error_kind` dispatcher checks
// `is_provider_config_rejection_message` first (observability.rs:199)
// so this routes to `ProviderConfigRejection` (kind="provider_config_rejection")
// rather than `BudgetExhausted` (kind="budget"). Both demote to
// info-level — no Sentry-volume regression — but downstream consumers
// that filter on the `kind` tag will see the rename.
// Backend balance gate at `api/rest.rs:582` is unaffected:
// it calls `is_budget_exhausted_message` independently before
// `expected_error_kind` is reached.
"insufficient balance",Also add a dispatcher-level test pinning the precedence:
#[test]
fn insufficient_balance_routes_to_provider_config_rejection_not_budget() {
// Pins the dispatcher precedence in observability.rs:199 vs 205 —
// both classifiers match this token, accidental reorder would flip
// the `kind` tag silently.
assert_eq!(
expected_error_kind("Insufficient Balance"),
Some(ExpectedErrorKind::ProviderConfigRejection),
);
}Verified / looks good
is_provider_config_rejection_http(ops.rs:506) gates on status{400, 404, 422}only — 402 isn't allowed, so ops.rs-level provider HTTP demotion path unaffected by this token.- Web channel caller (
web.rs:668) callsis_provider_config_rejection_messagedirectly without status gate — for 4ZF body, demotion is desired. - Test covers both wrapped wire shape (verbatim 4ZF) + bare upstream envelope.
- Case-insensitive matching at the matcher entry — sufficient.
- 1 file, additions only. coderabbit + graycyrus APPROVED. CI 30/30 green.
Happy to flip to approve once the doc-rewrite + precedence test land.
