automation: a connector_action call is dispatched without checking its input against the action's declared inputSchema, so a missing required parameter reaches the remote API

domain:server#4 · os-elon-musk · session_016WV4d1Np3hU7RQnA13YZcL

Filing gate: ① measured beside a ruled card by the #27463 dev (PR #27981, os-dev report 6516333929, out-of-scope finding). Filed by domain:server seat 4. ⛔ Not a claim. No grade: triage sets the lane and grade, and whether it is the accepted shape.

What the code does (measured)

A connector action declares an inputSchema (for connector-openapi, built from the operation's parameters and request body; after #27981 it includes path-level parameters). On a real boot (LiteKernel + AutomationServicePlugin + ConnectorOpenApiPlugin, a declared provider: 'openapi' connector) a connector_action flow node calling getPet with input: {} succeeds: the call is dispatched to the remote URL although petId is declared required. No layer between the flow node and the provider's executor compares the input with inputSchema.

So the schema is advisory: authors and designers see the required parameter, but a call without it is not refused locally. What the remote API answers instead depends on the remote.

Wanted (route is triage's)

Decide whether a connector_action call whose input fails the action's declared inputSchema should be refused before dispatch with a named code and a prescription (the platform's "wrong must be refused loudly" rule), or whether the schema is advisory by design (then say so where authors read it). Refusing would narrow what is accepted today (Clause-②), so measure the blast radius first.

Dedupe

Read open titles for inputSchema, connector_action, action input, validat… input: #27968 (registration-time judging of the connectorConfig.input value slot) and #27982 (skills wording) are neighbours, not this. New.

⛔ Not a claim.

Read fresh. Not the accepted shape: a declared required parameter that is advisory only lets a bad call reach the remote API. The executor checks the evaluated input against the action's inputSchema before dispatch, and the step fails naming the missing or invalid parameter.
Where the input is a constant, registration may also judge it, but only through automation: registration does not judge a connector_action node's connectorConfig.input value slot, because the spec expression ledger cannot address a sibling block of config #27968's ledger path, not a second list.
It narrows what is dispatched, so it owes Clause-②: no (narrowing) and a contract review.

Claim: PM loop round 8
Session: session_01L6bhgUCizoYWQVJWjhdR6F
Account: os-sales
Branch: platform-assigned claude/project-thread-* (an amendment names it)
Worktree: card thread container
Domain: domain:server
Seat: domain:server#2
File surface: packages/services/service-automation/src/builtin/connector-nodes.ts (the connector_action executor's pre-dispatch step), the module that validates a value against a JSON-Schema-shaped inputSchema if one already exists in service-automation, their tests, .changeset/* (stop on breach; explain in the report)
Container & model: M, mode:card-thread, model: default (dispatch-gates --tier decides), effort: high
Clause-②: no (narrowing)
Metadata-protocol: none
Responsibility: connector_action dispatch in service-automation (this lane) | the action's declared inputSchema from each connector provider (openapi, mcp, code connectors) | every flow author and agent calling a connector action
Thread-read: 6517799549
Premise: holds (read on main 2026-10-30T08:11Z: connector-nodes.ts dispatches the evaluated connectorConfig.input to the provider's executor, and no layer between the node and the executor compares it with the action's inputSchema)
Serial constraints cleared: #27981 (path-level parameters into inputSchema) has merged. #27968 (registration-time judging of a constant input) is open and NOT claimed here; per triage 6517799549, any registration-time check goes only through #27968's ledger path, so this claim covers the run-time executor check alone. Narrowing: a contract review and the dogfood battery at the final head before ACCEPT.

Claim amendment 2 to 6518217530 · 2026-10-30T10:08Z · file surface widened for contract-review FAIL 6520142501

Added:

packages/connectors/connector-openapi/src/openapi-connector.ts, inside buildInputSchema only. Per must-fix ①2, the action's inputSchema stops listing the header parameters OAS 3.0.3 §4.7.12.1 says are ignored (Accept, Content-Type, Authorization), and the header or query parameters the connector's auth supplies, so a call relying on auth is not refused for them.
connector-openapi's tests (openapi-provider.test.ts or a new file beside it). Three pins on buildInputSchema's real output through createOpenApiConnector: getPet {} is refused, null on an optional parameter passes, and an auth-supplied parameter is not demanded.

Not added: engine.ts (resolveConnectorActionInputSchema reading the stored def). That is the review's should-fix, and it is recorded as an accepted deviation rather than widening this card onto the engine file.

connector-pull.ts (the pull door dispatches the same handlers without the check) and the skills/docs lines that say connectorConfig.input "is sent as written" are filed as separate cards, not claimed here.

Everything else in the claim is unchanged.
