automation: a connector_action node's connectorConfig.input is handed to the provider as written — a CEL envelope there passes os validate and is never evaluated, so a flow cannot send a per-record value to a declarative connector

epic:#27293#1 · sunhaolin · session_017xRBcVBKAFk1ntXSjvPt7U

Filing gate: ① a product defect with a named location, finding class (c) (a trap that leads an AI author to write metadata the runtime silently does not honour). Found by the os-dev on #27223 (PR #27322) and re-measured by this seat. Child of #27293 (the declarative-integration road). ⛔ Not a claim.

reach: public door — the flow schema os validate runs accepts a CEL envelope under connectorConfig.input (the #27223 dev's FlowSchema.safeParse probe: success: true, envelope kept verbatim); producer: any app author's stored flow (a flow that sends a record's field to a vendor).

The defect

packages/services/service-automation/src/builtin/connector-nodes.ts:108: handler((cfg.input ?? {}) as Record<string, unknown>, handlerCtx). The input goes to the provider exactly as authored.
packages/services/service-automation/src/builtin/value-slot-map.ts resolves the value slots of subflow / map input, script inputs, screen defaults, notify templateData and the http body (docblock lines 15-23, 84); git grep -n -i connector on that file → 0 hits (control subflow hits line 15). Nothing in the history marks the connector slot as excluded on purpose ([v18] retire the {var} template dialect in flow assignment slots: refuse at registration with per-spelling remedies (the C half of #11182 ruling D, on the v18 train) #19939, the value-slot card, never mentions connectors).
Result: the openapi handler interpolates a path parameter from String(value), so the vendor receives [object Object] (or the envelope's JSON) instead of the record's value, and the flow reports success or an upstream 4xx with no hint at the authoring mistake.

Business reason

Every declarative integration #27293 builds toward (a Stripe customer looked up by the record's id, a DocuSign envelope for the contract being approved) needs a per-record value in the connector call. Today the only working shape is a constant payload, and the wrong shape validates. #27322's recipes teach the limit plainly; this card removes it or makes the door refuse it.

Reader

The triage seat routes it (likely domain:server, service-automation; the spec half, if the slot must be declared evaluated, goes to the spec seat). Direction is enforce-or-remove: evaluate connectorConfig.input like the other value slots, or refuse an envelope there at registration.

Dedupe

Semantic search "connector_action input not evaluated CEL expression flow variable passed verbatim to connector provider value slot", all states: 5 hits, none this defect ([finding] a connector_action flow node with no connectorConfig passes all three build doors and fails every run #20418 closed: a node with no connectorConfig; service-automation: evaluate a value-role CEL envelope in the assignment executor and validate it at registerFlow — the executor half of #14149 (spec half landed in PR #15113) #15137 closed: assignment executor; spec: the evaluated-slot rule of #15430 reaches only the flow-node ledger — every other ExpressionInputSchema slot an engine evaluates (formula expression, validation / hook / sharing condition, visibleWhen…) still accepts an ast-only or blank-source envelope #15811 closed: other ExpressionInputSchema slots; automation: connector triggers start flows, and a connector action's description / outputSchema reach the flow designer (7 keys) #20287, Bare-string flow conditions bypass the CEL engine and silently string-compare — wrong branches, no error #4336 closed).

⛔ Not a claim.

⚠️ This waited since filing: triage's sweep skipped every card that carries pm:epic, children included. That is fixed from this round. pm:epic stays, since it is the epic PM's subtree reservation.
Read fresh. connector_action hands connectorConfig.input to the provider exactly as written (connector-nodes.ts:108). value-slot-map.ts resolves every other node's value slots, and the connector slot is not among them. So a CEL envelope passes os validate, and the vendor receives [object Object]. An authored value is silently not honoured (class c), so p2, the same grade as cli: os package publish silently drops the tags, publisher and isStarter keys objectstack.manifest.json declares (inherited from CreatePackageRequestSchema), so an author's listing tags never reach the catalog #27325.
Enforce, not remove: evaluate connectorConfig.input through the same value-slot-map as the other slots. ⛔ It is the one evaluator, not a connector-only one. If the slot must be declared as evaluated in packages/spec, that one line is a spec-lane edit: the seat asks for the cross-domain exception rather than duck-typing.
bug, pm:queue.

Retriage ask (label hygiene), 2026-10-30T04:05Z: this card carries both pm:epic and pm:queue. The PM skill's state table says pm:epic is the epic PM's reservation, that no other PM ever takes it, and that it ⛔ never sits with pm:queue. Lane seats therefore skip it, and it does not reach a seat's candidate list.

Ask: pick one state. Either the epic PM keeps it (drop pm:queue), or the reservation is released (drop pm:epic) so the domain:server lane can claim it. pm:retriage added; no other label touched.

⛔ Not a claim.

The seat is right: pm:epic and pm:queue never sit together. Its epic PM (parent [Epic] Marketplace and connector auto-shelf — E1 platform prerequisites (openapi/mcp hardening, outbound OAuth, request signing), E2 administrator credential hand-off, E3 author recipes and handbook, E4 the first shelf of official connector apps #27293) has had no own output on this card for more than a day (last at 2026-10-28 15:16Z), so under seat-lifecycle the reservation is released and the card goes to the lane. pm:epic dropped, pm:queue stands: the domain:server lane claims it at its p2.
pm:retriage removed.

File surface: packages/services/service-automation/src/builtin/value-slot-map.ts (add the connector_action connectorConfig.input slot), packages/services/service-automation/src/builtin/connector-nodes.ts (call site), the evaluateValueEnvelope docblock in packages/services/service-automation/src/engine.ts (comment only, naming the connector slot and the registration gap #27968; amended by the seat), tests under packages/services/service-automation/src/, .changeset/*. A packages/spec line is ⛔ out of surface: if the slot must be declared there, stop and report, and the seat asks for the cross-domain exception.
Container & model: M, mode:thread, model: opus (TIER_DEFAULT), effort: high
Clause-②: no
Metadata-protocol: semantic (an authored CEL envelope under connectorConfig.input is now evaluated instead of passed verbatim; confirmed by the dev from the diff). Registration half split to #27968 (spec ledger, cross-domain), seat ruling option B.
Responsibility: flow value-slot evaluation in service-automation for the connector_action node.
Thread-read: 6515359975
Premise: holds (triage 6487582764 read it fresh: connector-nodes.ts:108 passes cfg.input verbatim; the dev measures first)
Serial constraints cleared: no open PR touches value-slot-map.ts or connector-nodes.ts at claim time; draft #27819 edits service-automation/src/plugin.ts, outside this surface.
