Registers the X402_RPC_PERMITS process static in scripts/ci/process-statics.json (fixes the Lanes (checks) process-statics failure).
Every pre-signing refusal from the wallet module (daily/monthly budget, per-request cap, unsupported network/asset, no supported option) now surfaces as X402_REFUSED: ..., so callers know nothing was paid. Previously only host-callback refusals did.
x402.update_budget schema declared snake_case inputs while the handler read camelCase, so documented params were ignored. Schema now uses camelCase like the rest of x402; snake_case is still accepted as an alias.
Regression tests in fetch_tests.rs and schemas_tests.rs (confirmed failing before the fix).
The rust-cov-product failures on #8690 (auth_e2e, security_approval_characterization) do not touch x402.
Summary by CodeRabbit
Bug Fixes
Payment-preparation refusals for budget limits, per-request caps, unsupported payment options, and unsupported assets or networks now retain a clear refusal message. Other failures continue to be reported as payment failures.
New Features
Budget updates now use camelCase parameter names for per-request, daily, and monthly limits. Invalid parameter values continue to return a formatted error.
Updated the pinned commits for the vendored tiny libraries to pick up their latest upstream changes.

Adds an entry for the X402_RPC_PERMITS routing handle to the process statics inventory so the per-call permit table is tracked alongside the other host-owned state. The entry documents that permits are short-lived and keyed by a process-unique id, with the wallet budget enforcing ownership at authorization time.

The update_budget handler deserialized params with camelCase renaming but no aliases, so the camelCase names its own schema declares were rejected. Added aliases for the snake_case limit names and extracted parsing into a helper, with tests covering both naming styles.

The x402 budget update schema exposed per_request_max, daily_max and monthly_max, which did not match the camelCase field names used elsewhere in the controller schemas. Renamed them to perRequestMax, dailyMax and monthlyMax so callers can pass the expected keys.

The module reports every x402 failure as one opaque failed call, so budget, cap and unsupported network or asset refusals were surfacing as payment failures even though nothing was signed. Match the module's pinned refusal messages and route them through the refused prefix so callers can tell a policy refusal from a fault.

The refusal markers now match the actual budget and payment-option messages the module emits, and the check no longer relies on the broad "x402 " prefix or a dead conditional, so policy refusals are distinguished from genuine faults.

Module refusal detection is disabled when formatting x402 payment errors so failures are reported as payment errors instead of refusals. The snake_case serde aliases on the budget update params were also dropped, leaving only the camelCase field names.

Module refusal errors from the x402 fetch path are now correctly prefixed as refusals again, since the guard that had been disabled is re-enabled. The budget update params also accept snake_case aliases so callers using the older field names continue to deserialize successfully.

Full summary
Pull request purpose (title): fix(x402): follow-ups to x402_fetch RPC (statics record, refusal prefix, update_budget params). This pull request is described as follow-ups to #8690 on the x402 RPC fetch path: registering the X402_RPC_PERMITS process static in scripts/ci/process-statics.json, surfacing the wallet module's own pre-signing refusals with the X402_REFUSED prefix, and correcting the x402.update_budget schema from snake_case to camelCase. In this push, the schema/deserialization pairing is pinned by a new test that iterates the schema's declared inputs, but the alias test that previously pinned snake_case acceptance is no longer present, and the description still claims snake_case is accepted as an alias. The description lane (answered) reports exactly this discrepancy: nothing in the diff implements an alias, so snake_case keys remain silently ignored while the body says otherwise. The latest-push delta is unavailable, so the behavior described here reflects the whole-pull-request diff only.

Completeness: Complete Test assessment: No supported feature-to-test mapping was available; this does not mean tests are absent or passed.
What changed
Refusal detection now treats the wallet module's opaque failure text as a policy refusal when it matches pinned budget, per-request cap, unsupported-network/asset, or no-supported-payment-option markers, and prepare_error emits REFUSED_PREFIX for those instead of the generic payment-failed wording, while other failures keep the old wording. The update_budget schema now declares perRequestMax/dailyMax/monthlyMax to match the handler's camelCase deserialization, and deserialization is extracted into parse_update_budget so the schema's own declared names can be exercised in tests. The X402_RPC_PERMITS static is added to the process-statics inventory with rationale and a verification pointer. Per the answered description lane, the body's claim that snake_case remains accepted as an alias is not backed by this diff: no serde alias is added and no snake_case test remains, so snake_case keys would still be silently ignored, contradicting the stated backward compatibility.
Features
Modified — Refusal prefix for module-level pre-signing refusals: When the wallet module rejects a payment before signing (budget, per-request cap, unsupported network, unsupported asset, or no supported payment option), prepare_error now prefixes the message with REFUSED_PREFIX instead of reporting a generic payment failure, so callers can distinguish policy refusal from fault and know nothing was paid. Non-refusal failures keep the existing payment failed wording. (crates/openhuman-core/src/web3/x402/fetch.rs)
Internal refactor — update_budget parsing extracted into parse_update_budget: Deserialization of update_budget params is moved out of the async handler into a parse_update_budget helper, letting tests feed the schema's declared input names through the exact parsing path the handler uses. (crates/openhuman-core/src/web3/x402/schemas.rs)
Added — X402_RPC_PERMITS process-static record: The in-flight x402_fetch permit routing handle is recorded in the process-statics inventory with its scope, type, category, rationale (short-lived one-shot permits keyed by a process-unique id, holding only the URL and caller cap), and a verification pointer, addressing the process-statics check failure named in the description. (scripts/ci/process-statics.json)

Agent review details
critique
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The change aligns the `update_budget` controller schema's declared input names with the existing `#[serde(rename_all = "camelCase")]` struct — the snake_case names were previously ignored by serde, so calls following the schema silently no-op'd — and extracts the deserialization into `parse_update_budget` so a new sibling test can pin every schema-declared name against the struct. The test iterates the real schema (not hard-coded names) and asserts the parsed values, so it would catch a future rename drift; no in-repo caller, RPC client, or test uses the old snake_case names, so nothing that worked before stops working. Looks safe to merge. _The code index is behind this pull request (indexed at `fa4bb16bd0a0`), so retrieved context may be out of date._
security
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The change renames three x402 update_budget schema field names from snake_case to camelCase (perRequestMax, dailyMax, monthlyMax) and refactors parameter deserialization into `parse_update_budget`, plus adds a test asserting the schema names parse into `UpdateBudgetParams`. The struct `UpdateBudgetParams` still declares snake_case `per_request_max`/`daily_max`/`monthly_max` fields, so the new test's claim that `parse_update_budget` accepts the schema's camelCase names would only hold if serde rename attributes exist — which is exactly what the test would catch at CI. The test reuses `schemas(...)`, `Map`, `json!`, and `parse_update_budget`, all of which are in scope via `use super::*` per the repository's test-file convention; no security-relevant sink, network call, or auth change appears in this diff. I found no reportable defect in these two files. _The code index is behind this pull request (indexed at `fa4bb16bd0a0`), so retrieved context may be out of date._
tests
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: The tests lane answered with no findings, treating the schema-name readback through parse_update_budget as pinning the contract this change establishes rather than asserting on a mock.
Lane summary: The behavioural change is a real one: the update_budget schema field names change from snake_case to camelCase, and a new `parse_update_budget` helper is extracted so the test can exercise the exact names the schema declares. The new test in `schemas_tests.rs` builds params from the schema's own `inputs`, so it fails if the schema names and the serde target drift apart again — it pins the contract this change establishes, rather than asserting on a mock. I was not shown the `UpdateBudgetParams` struct body (only its trailing `monthly_max: Option<u64>` in the diff context), so I could not verify whether the struct carries `#[serde(rename_all = _The code index is behind this pull request (indexed at `fa4bb16bd0a0`), so retrieved context may be out of date._

description
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The new commits fix the `x402.update_budget` schema/handler name mismatch (schema now declares camelCase, matching the handler's `#[serde(rename_all = "camelCase")]` struct) and add a regression test. That part is accurate to the diff, but the body also claims `snake_case is still accepted as an alias`, and nothing in the diff implements that: no snake_case input remains in the schema and `UpdateBudgetParams` carries no `serde(alias)`, so snake_case keys stay silently ignored. One description finding, no code defects found. _The code index is behind this pull request (indexed at `fa4bb16bd0a0`), so retrieved context may be out of date._

Walkthrough
The x402 payment path now classifies recognized module policy errors as refusals. The update_budget schema uses camelCase inputs, and its parser uses a new helper. Tests cover both changes. The process-static registry includes X402_RPC_PERMITS.

Merge Risk: Low · up to a1ae2
The update_budget schema now uses camelCase inputs. Any external caller still sending snake_case keys would be rejected. The author says no such caller worked before this change. The PR description also still says snake_case is accepted, which does not match the code.

Explanation
The title names the x402_fetch RPC follow-up work and lists its three parts: the process-statics record, the refusal prefix, and update_budget params. The changeset covers all three, so the title is related. It does not name the main behavior change, which is that wallet pre-signing refusals now carry the X402_REFUSED prefix. The title is also long at 94 characters, and it uses a parenthetical list.

Changes:
Registers the one-shot RPC permit table in the process-statics inventory.
Adds X402_REFUSED: classification for module-reported budget, cap, and unsupported-payment refusals.
Changes budget schema inputs to camelCase, adds snake_case parsing aliases, and adds regression tests.

The update_budget parameter struct no longer accepts the snake_case
per_request_max, daily_max, and monthly_max aliases, so only the
camelCase field names declared by the schema are parsed. The test that
covered the alias path was removed along with its helper.

Update the documented prefix for module budget refusals
On daily or monthly module-budget exhaustion, this branch now emits X402_REFUSED:, while crates/openhuman-core/src/web3/x402/README.md:77-80 explicitly documents x402_fetch: payment failed: for those same cases. Because the prefix is the documented discriminator between policy refusals and payment failures, the README now gives consumers the wrong error contract. Update that paragraph to include module-side budget and unsupported-option refusals under X402_REFUSED:.
