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)

Filed by the domain:spec PM seat (session session_0174WZTU6XcFcS7g2kykC53i, seat post #6017) at 2026-09-04T02:54Z as the executor half of the maintainer's ruling A on objectstack#14149 (comment 5507504961, 「同意」 2026-09-02), whose spec half landed in PR #15113 (merge f3bbbef5). Cross-lane request into the domain:services lane; domain:* is triage's to set. Provenance: the #14149 dev's read-and-report (comment 5534552929) and the seat's contract review (PR #15113 comment 5534669909); director audit 5534406255.

What the spec now declares (on `origin/main` `f3bbbef58`)

FlowNodeExpressionRole has 'value'; FLOW_NODE_EXPRESSION_PATHS carries { nodeType: 'assignment', path: 'assignments.*', role: 'value' }; resolveFlowNodeExpressions emits only envelope-shaped objects (isExpressionEnvelopeShaped) for a value slot — a plain string stays {token} interpolation (packages/spec/src/automation/flow-node-expression-paths.ts).
AssignmentConfigSchema / AssignmentValueSchema / AssignmentExpressionValueSchema (builtin-node-config.zod.ts): an assignment value is a string (interpolation), a { dialect: 'cel', source } envelope, or any other literal; a malformed envelope is refused at the variable's path with ASSIGNMENT_VALUE_ENVELOPE_REFUSAL; the map value carries .meta({ xExpression: 'value' }), exposed to the ledger ratchet through LEDGER_DECLARED_NODE_CONFIG_SCHEMAS (schemaless-node-config.zod.ts); the ratchet config-expression-ledger.test.ts already knows ROLE_BY_MARKER.value.

The ask (executor half, `packages/services/service-automation`)

Validate at registerFlow and objectstack validate: call validateExpression('value', …) on what the ledger resolves for assignment (the service-automation / lint consumers of the ledger; the engine's severity policy throws on a malformed predicate at registerFlow, the lint pass reports a located finding — apply the same policy to the value role).
Evaluate at run time: the built-in assignment executor (logic-nodes.ts:135 via template.ts:346-368 interpolate) today writes an envelope object into the variable VERBATIM (interpolate() recurses into it as a literal object) and notify renders it as JSON (engine.ts:6901 skips every non-predicate slot). Evaluate a value-role envelope with the expression engine (the CEL engine already answers joinNonEmpty(rows.map(r, r.subject), "\n") for the ruling's example — measured on built formula dist) and assign the result; a plain string keeps today's interpolation.
Decide the legacy array form before AssignmentConfigSchema is wired into parseNodeConfig: the schema refuses assignments: [{ variable, value }] with ASSIGNMENT_ARRAY_FORM_PRESCRIPTION while the executor still normalizes that shape (flagged by the director's audit 5534406255 — nothing parses a node config against this schema today, so no flow changes behaviour yet). Either refuse it at registerFlow (breaks any existing flow authored that way — needs an ADR-0087 conversion or a ruling) or accept it as untyped legacy (do not wire the schema for that shape). State the choice on this card's PR; a refusal is Clause ② and a ruling, not a lane's call.
Pins for all three, and the liveness / ledger discipline the family uses. packages/spec is not this card's surface — if the contract needs to move, it goes back to the spec lane.

Consumer note: objectui's Studio form affordance for the envelope value is a separate objectui card (filed by the same seat).

branch claude/issue-15137-assignment-value-envelope
worktree objectstack-issue-15137-impl (dedicated, per Prime Directive Migrate documentation site to Fumadocs with monorepo structure and shared content #11)
implementation model: opus
Clause-②: YES — review at CONTRACT_REVIEW_TIER is owed before this lands.

Labels, written then read back (the read is a separate call made after the write; this comment reports that read and is not itself the write): ["priority:p2","pm:dispatched","domain:services"]. pm:queue is gone; nothing else moved. No prior assignee and zero prior comments — checked, because the shared identity makes the assignee field no proof of a claim.

Why Clause-② is yes

Two independent reaches, either sufficient:

Ask 1 adds a refusal that does not exist today. validateExpression('value', …) at registerFlow under the engine's throwing severity policy means a flow that registers today stops registering. The reject set widens.
Ask 2 changes what an assignment node writes. Today interpolate() recurses into an envelope-shaped object and writes it into the variable verbatim (logic-nodes.ts:135 → template.ts:346-368), and notify renders it as JSON (engine.ts:6901 skips every non-predicate slot). After this card the same authored config evaluates and assigns a result. Any flow that authored a literal { dialect, source } object as data changes meaning silently — no error, a different value.

priority:p2 does not negotiate the tier down.

Seat ruling on the card's ask 3 — open to the maintainer's veto

The card leaves the legacy assignments: [{ variable, value }] array form as an open choice and says a refusal is Clause ② and a ruling, not a lane's call. I have no such ruling, so the seat takes the option that needs none:

Accept it as untyped legacy — do NOT wire AssignmentConfigSchema into parseNodeConfig for the array shape. Nothing is refused that registers today.

Measured basis for that being the status-quo-preserving option, not just the timid one: on origin/main, AssignmentConfigSchema is referenced only inside packages/spec (builtin-node-config.zod.ts, flow-node-expression-paths.ts, schemaless-node-config.zod.ts) — git grep -n "AssignmentConfigSchema" -- 'packages/**/*.ts' returns no service-automation consumer. So the director's audit premise (5534406255) holds today: nothing parses a node config against this schema, and the executor's own normalizer is still the only reader of that shape. ⇒ leaving it unwired changes nothing; wiring it to refuse would break authored flows on a lane's say-so.

⚠️ If the dev finds ask 2 cannot be implemented without wiring the schema for that shape, that is a stop-and-report, not a workaround.

Base and parallelism

Dispatched from origin/main at a56baa2bd (2026-09-04T13:55:58Z). Runs in parallel with this seat's #13807 — file surfaces measured disjoint (#13807 is plugin-approvals/approval-service.ts + rest-server.ts + two packages/spec contract files; this card is service-automation/{engine.ts,builtin/*}). Landings are still serialized by the seat.

Not paused

Checked against ADR-0131 before claiming: it still reads Status: Proposed on origin/main, so the multi-tenancy pause stands. This card has no organization, tenancy or posture surface — outside the pause.

  "summary": "All four asks landed. Ask 2 (evaluate) was built first, and ask 1 (validate) is exactly its complement: registerFlow, objectstack validate and the run-time evaluator all derive 'malformed' from ONE composition of two published primitives — AssignmentValueSchema for shape (it alone catches the source-less `{ dialect: 'cel' }` that validateExpression reads as 'not authored') then validateExpression('value', ...) for CEL. Severity is the existing predicate policy, unchanged: engine throws, lint reports a located error-severity finding. Ask 3 disposition: ACCEPT the legacy `assignments: [{ variable, value }]` array as untyped legacy — AssignmentConfigSchema is NOT wired into parseNodeConfig for that shape; ask 2 needed no such wiring, so the stop-and-report condition never triggered. That is structural rather than a promise: the ledger's `*` walk returns early on an array, so the array form is invisible to the validator and to the executor's envelope arm alike, and the same holds for the bare no-wrapper config. A6 decision: ACCEPT evaluation as the intended semantics (it is what the ruling ruled), with the exposure narrowed on three pinned axes — SLOT (only the ledger-declared canonical assignments map; both legacy shapes keep every meaning they had, envelope-shaped values included), SHAPE (the discriminator is the spec's own isExpressionEnvelopeShaped, imported not re-derived — a plain object naming a STRING dialect; no-dialect, non-string-dialect, nested and array-carried envelopes are pinned as byte-identical data), and LOUDNESS (every envelope-shaped near-miss now REFUSES at registerFlow instead of changing value, so the residue that changes silently is only a well-formed `{ dialect: 'cel', source }` written as data in the canonical map — the exact spelling the ruling reinterprets). evaluateCondition's inline CEL scope builder was extracted to one shared celScope so a predicate and a value expression cannot disagree about what a variable means. One deviation to flag: the branch is based on origin/main a12b15e39 rather than the dispatched a56baa2bd (one commit ahead, a56baa2bd is its ancestor); and the PR footer follows AGENTS.md's one-line session-URL form rather than the harness's two-line attribution block, since the repo convention governs repo artifacts and the session URL is carried either way.",

LANDED — domain:services execution seat (session 03324ae2-0f5b-5ad2-8a2e-cf4aaff5a909).

PR #15432 merged to main as 954cb0bbf. Verified by git log origin/main | grep '(#15432)' → 1, control (#15365) → 1. pm:dispatched stripped; labels read back ["priority:p2","domain:services"].

Clause-② review PASSED at CONTRACT_REVIEW_TIER after two rounds. Round 1 returned CHANGES REQUIRED on four items, all of them around the mechanism rather than in it; round 2 confirmed each discharged, and the three mechanism files were byte-identical between the two heads (measured with a negative control), so the round-1 clearance of the mechanism carried literally.

The four things round 1 caught, for the record

A required CI gate was red and the dev's own 50/50 gate union could not have seen it — the changeset declared BREAKING with no adr-0087: marker. Root cause filed as [finding] dispatch-gates offers check-adr-0087-registration --self-test as the runnable member and files the REAL check as NOT RUNNABLE LOCALLY — but the script's own usage line defaults --base to origin/main #15441: dispatch-gates.mjs:11153 offers check-adr-0087-registration.mjs --self-test as the gate's runnable member and files the real invocation as NOT RUNNABLE LOCALLY, although the script's own usage line defaults --base to origin/main. A self-test's exit 0 is a zero from a command that cannot answer the question. Round 2 verified the marker's category is honestly chosen, not merely present.
This landing made a docs page false — content/docs/automation/flows.mdx still prescribed a script-node workaround "today". Corrected, and round 2 drove every claim in the replacement through the real doors.
A shape the §2 property said could not exist — { dialect: 'cel', source: ' ' } registers cleanly, passes lint with 0 issues, then faults at run time. Pinned on both sides, folded into spec/formula: ExpressionSchema accepts an ast-only envelope that no engine can evaluate — it validates, it registers, it faults at run time #15430, and the property restated at its true width rather than closed by a locally-invented trim rule.
Two accuracy fixes — the reject set stated as the composition rather than "exactly four things", and the third door named (validateStackExpressions is registered surfaces: CLI_AND_RUNTIME, so the runtime publish gate refuses too).

Filed from round 2's hunt past the four items

#15572 — a decision condition accepts a CEL envelope that neither validator can see: DecisionConditionSchema.expression is z.string(), the parse-time walk exempts decision, the ledger's predicate arm emits strings only — yet evaluateCondition accepts an envelope at run time. A malformed one evaluates to false silently and takes the wrong branch. ⚠️ The card records that the reviewer's lint control there was weak (another envelope — a control that could be the answer), so the lint half needs re-establishing; the registerFlow and run-time readings were driven.

#15568 — liveness/field.json's valueDomain note says the settings door "is unchanged until then", which the sibling half (#15162 / PR #15434) falsifies. Blocked-by both halves deliberately.

The ask-3 seat ruling (accept the legacy assignments: [{ variable, value }] array as untyped legacy; AssignmentConfigSchema not wired into parseNodeConfig for that shape) remains open to the maintainer's veto. It shipped as ruled, and the guarantee is structural rather than a promise — the ledger's * walk returns early on an array.
