+Reconcile the remaining flat builtins' declared config against what their
+executors read (#4045 — the CRUD / screen / map step, after notify / http /
+connector in #4210).
+
+**Six executor-derived Zod contracts.** `GetRecordConfigSchema`,
+`CreateRecordConfigSchema`, `UpdateRecordConfigSchema`,
+`DeleteRecordConfigSchema`, `ScreenConfigSchema` (+ `ScreenFieldConfigSchema`)
+and `MapConfigSchema` in `automation/builtin-node-config.zod.ts`, each written
+by reading the executor rather than transcribing the descriptor literal, so the
+new bidirectional ledger test is evidence rather than a tautology. Contract
+exports only — nothing parses with them yet (#4045 step 3b, gated on the #4059
+warning data).
+
+**Seven capabilities the executors honour are now authorable.** Each was read
+by the executor and offered by no form — online or offline — so it was reachable
+only by hand-written metadata:
+
+- `get_record.fields` — the query projection, passed straight into
+  `find`/`findOne`;
+- `screen.recordId` — the record `mode: 'edit'` opens; the form declared the
+  edit mode while offering no way to name its target;
+- `screen.fields[].options` / `defaultValue` / `placeholder` — all three
+  forwarded into the ScreenSpec the client renders, so a select field's choices
+  could not be authored in Studio at all. Same nested repeater position as the
+  `visibleWhen` gap #3528 was filed for;
+- `map.indexVariable` and `map.input` — the index binding and the per-item
+  subflow params.
+
+**`map`'s undeclared `flow` alias graduates to the conversion layer.** The
+executor carried `cfg.flowName ?? cfg.flow` for a spelling no schema ever
+described — the `notify.source` shape (Prime Directive #12). The bare fallback
+is deleted and `flow-node-map-flow-alias` (protocol 17, retires at 18) renames
+it at load, including the `AutomationEngine.registerFlow` rehydration seam.
+
+**`assignment` is pinned as deliberately un-reconcilable**, with the reason on
+record: with no `assignments` wrapper its top-level config keys ARE the author's
+variable names, so no fixed key set can describe it and a catchall Zod would
+reconcile vacuously. What the ledger pins instead is that the form offers
+exactly the canonical `assignments` map and that the map stays open.
+
+With this, every builtin that publishes a `configSchema` is reconciled against
+its executor, and the ones that publish none each have a recorded reason.

+
+Config contracts for the remaining flat builtins — the CRUD quartet
+
+(`get_record` / `create_record` / `update_record` / `delete_record`),
+
+`screen`, and `map` (#4045). Sibling of `io-node-config.zod.ts`
+
+(notify / http) and `control-flow.zod.ts` (loop / parallel / try_catch).
+
+## Provenance — written from the executors, not from the forms
+
+Each schema was derived by reading what the executor actually does with
+
+`node.config` (`service-automation/builtin/crud-nodes.ts`,
+
+`screen-nodes.ts`, `map-node.ts`), **not** by transcribing the hand-written
+
+`configSchema` literal on the node's descriptor. The two artifacts are
+
+reconciled bidirectionally by `builtin-node-form-zod-ledger.test.ts` in
+
+`service-automation`; a Zod copied from the form would make that
+
+reconciliation a tautology (#4045).
+
+Writing these against the executors is what surfaced the drift the
+
+reconciliation exists to catch — keys the executors read that no form
+
+offered anywhere (`get_record.fields`, `screen.recordId`, the screen
+
+field-item keys `options`/`defaultValue`/`placeholder`, `map.indexVariable`,
+
+`map.input`), and the undeclared `map.flow` alias, which graduated into the
+
+ADR-0087 D2 conversion layer like `notify.source` before it.
+
+## What these schemas are (and are not) wired to
+
+Contract exports only — no engine path `parse()`s a node config with them
+
+today, so registering a flow behaves exactly as before. Wiring the executors
+
+to parse is deliberately deferred until the #4059 undeclared-key warning has
+
+measured a release's worth of real metadata (#4045 step 3b).
+
+Deliberately absent:
+
+- `assignment` — its config cannot be described by a fixed key set: with no
+
+`assignments` wrapper the TOP-LEVEL config keys ARE the author's variable
+
+names (logic-nodes.ts). The ledger test pins that exemption with its
+
+reason instead of pretending a shape.
+
+- `decision` / `script` / `subflow` / `wait` / `connector_action` — the
+
+deliberately-schemaless class (config-schemas.test.ts); their contracts
+
+live elsewhere (edges, sibling blocks, conditional forms).

 `connector_action` gets the same lift for the opposite reason (#4045). Its contract also lives in a declared sibling block (`connectorConfig`), and the executor never read `config` at all — but the node's descriptor published a `configSchema` declaring `connectorId`/`actionId`/`input` as `config` keys, and the Studio inspector derives its form from a published schema, so schema-driven authoring wrote the trio to the wrong place and produced nodes that refused to dispatch. The conversion lifts the trio onto the declared block (declared keys win; a lift that cannot complete the required connectorId+actionId pair leaves the node untouched rather than turning a step-time refusal into a load failure), and the descriptor stops publishing the mis-rooted schema.
 
+The reconciliation that found those also found `map`, whose executor read a bare `cfg.flowName ?? cfg.flow` for an undeclared `flow` spelling no schema ever described (#4045). A pure rename, graduated the same way, so the executor reads only the canonical `flowName`.
+
 And it removes the RLS-policy key `priority` (#3896 security audit): promised "conflict resolution" that cannot exist, because applicable policies OR-combine (most permissive wins) — there is never a conflict to order, and nothing ever read the key (call graph closed across the collection site, the projection round-trip and the compiler). A pure lossless delete: outcomes are identical with or without it; the schema tombstones the key with the same prescription.
 
 The same close-out retires the four inert tool authoring keys (`category`, `permissions`, `active`, `builtIn`): none is part of AIToolDefinition and no execution path read them. Two were misleading in the dangerous direction — `permissions` promised an invocation gate nothing enforced, and `active: false` read as "withdrawn" while the tool kept reaching the LLM tool set. Lossless deletes; the strict ToolSchema rejects each with its prescription.
