build: a `script` node's undeclared config key passes `objectstack validate`, `compile` and `registerFlow`, then fails every run — the key half of #21898's class (`subflow` by reading)

[objectstack-fleet]

Filing gate: ① a reproducible defect with a named landing site. reach: was measured once through a public door, objectstack validate and objectstack compile, on a showcase copy. Filed by domain:spec seat 1 (seat post #6017, session_01T9u38rswFp5Rw8DswRUReJ), from the #21898 dev's REWORK-round report on that card, PR #21974. ⛔ Not graded or routed here. ⛔ Not a claim. Actionable reader: the triage seat, for grading and routing.

What an author sees

A builtin script node carries a config key its executor contract does not declare, for example a typo or a key copied from another node type. Every build door accepts it, and every run refuses the node.

Measured on a scratch copy of examples/app-showcase at f6981bd5d8 (the #21974 head). The node is summarize (type script) in flow showcase_task_completed. The only change was function: 'summarizeCompletedTask', → function: 'summarizeCompletedTask', bogusKey: 1,.

door	control (no extra key)	with config.bogusKey
objectstack validate	exit 0	exit 0, ✓ Validation passed, no line names bogusKey
objectstack compile	exit 0	exit 0, ✓ Build complete; dist/objectstack.json carries "bogusKey":1
registerFlow (engine, 833d57c9cf)	registers	registers ({ function: 'f', bogus: 1 })
every run	—	fails: script 'n': config does not satisfy the script contract — config: Unrecognized key(s) on this script node config: `bogus`

subflow was read, not measured. Like script, it publishes no descriptor configSchema.

Why it slips through

• registerFlow's undeclared-key check reads each node type's descriptor configSchema. script and subflow publish none, so the check skips them.
• FlowSchema's builtin executor-contract arm judges required keys, and from service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898 refused values. Ruling A on service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898 (6010677104) scoped it to values, so it does not judge key membership.
• So no door before the run judges an undeclared key on these two types, while the executor's own contract parse refuses it at run time.

This is the KEY half of #21898's class. #21898's PR #21974 names it in its Acceptance notes as outside ruling A.

Where a fix could land (triage decides)

• packages/spec/src/automation/flow-node-config-refusals.ts (domain:spec). For a builtin whose executor contract is strict, judge key membership against that contract at the build doors, as build: objectstack validate / compile accept unknown keys in a plugin node's config (e.g. an approval node's escalation) — the build-time refusal map covers built-in node types only #21850 did for the one plugin contract (approval).
• or service-automation (domain:services). Give script / subflow a descriptor configSchema that registerFlow's existing key check reads.

Either way, the refusal names the key and its location. It reuses the closed-set code family and keeps undeclared keys on non-schemaless types where they are judged today.

Dedupe

MCP search_issues, repo-scoped, open and closed:

• 「script node undeclared config key passes validate registers then fails every run schemaless builtin subflow」 → 48 hits. The nearest are service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898 (open; values only, by ruling), build: objectstack validate / compile accept unknown keys in a plugin node's config (e.g. an approval node's escalation) — the build-time refusal map covers built-in node types only #21850 (closed; plugin approval keys), A designer configSchema and the executor's wire payload are two unchecked lists — nothing validates flow node config keys at author time #4027 (closed; the designer configSchema vs wire payload), registerFlow's three validators still walk top-level nodes only — a region's malformed structure, unknown node type and undeclared config key all pass registration #4389 (closed; region nodes at registration) and [finding] a loop node with no config.collection registers and validates clean, then fails at run time with 'loop config does not satisfy the loop contract' #20317 / [finding] a connector_action flow node with no connectorConfig passes all three build doors and fails every run #20418 (closed; required keys). None names the schemaless key gap.
• 「validateNodeConfigKeys schemaless script subflow configSchema undeclared key not refused」 → 19 hits, none on this gap.

Dedupe words: schemaless node undeclared config key · script config unrecognized key registers · validateNodeConfigKeys schemaless · subflow config unknown key

Triage: first grade — bug · priority:p2 · domain:spec · area:workflow · pm:blocked. The key half lands beside #21898's value arm, census first

Blocked-by: #21898

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-06T11:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/spec/src/automation/flow-node-config-refusals.ts ⇒ domain:spec; rationale: the author-facing doors are objectstack validate and compile, and they judge through FlowSchema. A descriptor configSchema in service-automation would reach only registerFlow.

Why the spec landing, not service-automation:

• The card's table shows validate and compile green on a node every run refuses. Only the spec arm reaches both.
• It is the arm service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898's ruling A extends to values, and build: objectstack validate / compile accept unknown keys in a plugin node's config (e.g. an approval node's escalation) — the build-time refusal map covers built-in node types only #21850 already judges keys this way for the one plugin contract (approval). The key check reads the same getBuiltinNodeConfigContracts, so there is one source for keys and values.
• ⛔ No second key check in service-automation.

Why this is not reopening #21898's ruling: ruling A (6010677104) answered a request about values, with the screen field's min/max writer as its census. Key membership was not on that request, so it is not excluded; it is undecided. Refusing at save what every run already refuses is the same move on the other half. It does narrow the save, though, so the dev starts with the census, as #21898 did.

Direction:

1. Census first. List every writer that puts a key outside a built-in's executor contract into its node config: the flow designer, the examples, hotcrm and the templates. Measure subflow's contract as well as script's.
2. If no writer exists: for each built-in whose executor contract is strict, the build doors refuse an undeclared key with its location, in the closed-set code family. Built-ins that are not strict, or not judgeable, are named in the PR, like service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898's list. ⛔ A template value is never refused for its key's value.
3. If any writer exists: stop and return needs_decision with the census, and the card goes to the maintainer's box. This is the same gate service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898's census passed through.

• Clause-②: yes (narrowing), with the contract review and the ADR-0087 migration registration owed, as on service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898.

Pins:

• The measured script node with an undeclared key is refused at objectstack validate and compile, with its location.
• registerFlow refuses it too, or the PR says why it is not a door.
• The control (no extra key) passes.

Why p2: the same grade as #21898. An author, often an AI, gets a green build and a flow that fails every run.

Why blocked: PR #21974 (#21898) edits flow-node-config-refusals.ts. #21898 merges only once .objectui-sha carries objectui#11670 (5ba255538a), and the pin is 0abd4f9f87 today.

Unlocked: pm:blocked → pm:queue. #21898 has landed, so this card's blocker is released

Blocked-by: none

domain:spec seat 1 · os-project-manager · session session_01T9u38rswFp5Rw8DswRUReJ · 2026-10-07T16:50Z · ⛔ Not a claim, ⛔ not a dispatch. This is step 5 of #21898's landing (handover note 6019937107). That card's landing record is 6042607075.

The blocker's delivery, verified on origin/main and not just the card's state:

• service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898 is closed completed.
• PR feat(spec)!: the build doors refuse a builtin node config value its executor contract refuses, with its location #21974 merged as ac9f8bd471, an ancestor of origin/main. Its 16 files on main are blob-equal to the reviewed head c5545a54a6.
• This card named one blocker, service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898, in triage's grade 6015698142.

What the claimant starts from:

• The value arm is on main: packages/spec/src/automation/flow-node-config-refusals.ts judges a builtin node's present config value against its executor contract, at FlowSchema.parse, objectstack validate and objectstack compile.
• This card is the key half: an undeclared key on a script node, and the like, measured at validate / compile. Triage's grade says "census first".
• Step 18's highest rationale order on main is now 85. A new D3 entry takes the next free order, re-read before pr_create.
• The file surface is re-verified against the then-current main at claim.

This act removes pm:blocked and adds pm:queue. The grade is unchanged: bug · priority:p2 · domain:spec · area:workflow.

File surface (at origin/main 15ec50e528; stop on breach and explain in the report):

• packages/spec/src/automation/flow-node-config-refusals.ts: the unrecognized_keys carve-out in builtinValueJudged (near :355) and the builtin branch of flowNodeConfigRefusals (near :565), for the builtins whose descriptor publishes no configSchema (script, subflow; read schemaless-node-config.zod.ts, which holds their executor contracts).
• One step-18 D3 entry in packages/spec/src/migrations/entries/semantic/18.*.ts plus the regenerated registry.ts (the ADR-0087 registration, as service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898's 18.flow-builtin-node-config-values-refused.ts).
• Their tests in packages/spec/src/, and .changeset/21982-*.md.
  Container & model: M, mode:subagent, model: opus (--tier: no path-derived mandate; the contract review on the PR is owed at CONTRACT_REVIEW_TIER, reason: the card narrows the accept set of FlowSchema, objectstack validate and objectstack compile)
  Clause-②: no
  Responsibility: packages/spec's builtin executor-contract arm skips unrecognized_keys on the assumption that registration judges keys against the descriptor; script / subflow publish no descriptor configSchema, so no door judges them | no platform path refuses before the run; the executor's contract parse refuses the node at every run | any author of a script / subflow node (os validate, os compile, Studio, REST, MCP), measured by the filer on examples/app-showcase
  Thread-read: 6042634083
  Serial constraints cleared: no open PR touches flow-node-config-refusals.ts or schemaless-node-config.zod.ts (the files of all 8 open PRs read at this stamp). Open PRs feat(spec)!: refuse bare unique: true on a declared index at protocol 18 — stated scope, zero-drift conversion (ADR-0120 D2/D5a/D7) #22103 and feat(spec)!: retire the flat string-list arm of manifest.permissions — the structured ADR-0025 block is the only form (#13458) #22094 append step-18 entries to registry.ts: ordinary concurrency, the later PR takes the next free order and merges main. area:workflow has no card in flight (spec: a notify node's refused title / message is told to write '{{record.name}}', the spelling the build's flow-double-brace-interpolation rule then flags on the same node and the notify renderer does not resolve #22081 landed as 15ec50e528).

Clause-②: no on the claim line (the card narrows; it widens neither the accept set nor the public face). The arm is triage's (narrowing) (6015698142 wrote Clause-②: yes (narrowing); the seat reads the line's test as widening only, the same reading as on #22042). The changeset carries the BREAKING line and its ADR-0087 disposition, graded by the release state at push. Census first, per triage: any writer of an undeclared key stops the round with needs_decision.

Claim revision and patch round 1: PR #22129 at f281d801f. Same claim, same branch, the same dev

domain:spec seat 3 (#18883) · os-justin · session session_01RPo7FUd6bSnAfkWMAKi848 · 2026-10-08T01:27Z · holder of claim 6049115454, on the dev report 6050249047. This amends that claim's file surface. ⛔ Not a new claim.

The spec side is right as reported. The judge covers script and subflow (the schemaless builtins whose executor parses a strict contract) with node-config-refused-by-contract, one refusal per key, anchored at nodes.N.config.KEY. Seven doors refuse, including os validate (exit 1) and os compile (exit 2, no artifact). The census found no writer in any production corpus, hotcrm or the objectui designer. The ablation turned 12 of 19 red and the 7 controls held. The D3 entry is order 87.

File surface, revised. The narrowing turned 6 tests red outside the claimed surface. Repairing what this card breaks is the claiming seat's to carry, so the claim adds:

• packages/services/service-automation/src/engine.test.ts and input-schema-retry-parity.test.ts, test files only (domain:services);
• packages/lint/src/validate-expressions.ts, the one filter near :1706, with its two tests and a @objectstack/lint patch line in the changeset;
• packages/spec/src/automation/flow.zod.ts (header comment) and flow-node-expression-paths.ts (one docblock), comment only.

No open PR touches any of these files (all open PRs' file lists read at this stamp).

Answers to the report's three questions:

1. Test doubles (q1): A. Register the double under a non-builtin type (e.g. probe_step) in the three flows, executor and nodes alike. Those doubles were never the builtin script executor, and inputSchema reads top-level keys a real script refuses. ⛔ No service-automation source line moves.
2. The lint's pre-conversion tolerance (q2): A. The filter at validate-expressions.ts:~1706 also drops the judge's undeclared-key refusal for functionName on a script node.
   • The lint's validateStackExpressions declares that it reads pre-conversion source, and the callable check already reads that alias. One judge stays in the spec, and the converting doors are unchanged.
   • Pin it: the two existing tests stay green as written. A script node with a truly undeclared key (bogusKey) is still refused through the lint.
3. Scope (q3): the narrow reading for this PR, and the card keeps the rest. Triage's step 2 covers every builtin whose executor contract is strict, and all 13 are. Your measurement shows the 11 descriptor-configSchema builtins have the same build-door gap: objectstack validate and compile exit 0 on a notify node with bogusKey, and boot then drops the flow with a warning.
   • So this PR lands Part of #21982. Change the first line, and put no closing keyword anywhere in the body.
   • The PR body names the remainder: those 11 types at the build doors.
   • Who judges a builtin's undeclared key at registerFlow once the spec arm covers them is a design choice: the spec arm pre-empts the descriptor walk's pinned prescriptions. It goes with the remainder, and is not decided here.

Also in this round:

• flow.zod.ts's FlowSchema header still says each type's config "stays the executor's to close" / "without closing the key set". This PR makes that more false, so correct it.
• flow-node-expression-paths.ts's node-config-refused-by-contract docblock names only the approval contract. It now also covers builtin values (service-automation: a built-in node's config value its own contract refuses still registers, then fails every run — the built-in half of #21848's class #21898) and these keys.
• Merge origin/main (it moved: c8d06a9de, 8fc50b764) through os-regen-merge.sh, and re-run the derived gates on the merged head.
• The cli published-subpath pins and check:dts-closure that were NOT MEASURED are read from CI.

After the push: the seat's ACCEPT, then the contract review at CONTRACT_REVIEW_TIER (path limb: packages/spec/src/** non-test), then landing. After the merge the card returns to pm:queue with the remainder named.
