+feat(spec)!: an authored connector entry refuses a top-level key it does not declare; the connector read withholds URL credential parts and a non-object `auth`
+
+Clause-②: no (narrowing)
+Metadata-protocol: narrowed
+
+<!-- adr-0087: registered connector-entry-undeclared-key-refused -->
+
+**BREAKING** accept-set narrowing on an authored connector entry (`DeclarativeConnectorEntrySchema`), at every door that parses it: `defineStack({ connectors })`, `os validate` / `os compile`, the metadata plugin's artifact load at boot and on reload, and the metadata save door `PUT /api/v1/meta/connector/:name`.
+
+- **Before.** The entry was a plain object: a top-level key it does not declare parsed green and meant nothing to the runtime.
+- **Now.** The entry is closed. Such a key is refused by name with a located error (`unrecognized_keys` at the entry; at the save door `422 INVALID_METADATA`). A credential-shaped key (`apiKey`, `token`, `secret`, `password`, …) meets the `auth.credentialRef` prescription, and a provider setting written at the top level (`baseUrl`, `spec`, `transport`, `headers`, …) is pointed at `providerConfig`. The ADR-0010 protection envelope stays declared, so a package-stamped entry still parses. An artifact `os build` wrote carries no undeclared key (it serializes the parsed stack), so only a hand-assembled artifact can meet the refusal at boot.
+- **Unchanged.** `ConnectorSchema` — the def a plugin hands to `registerConnector`, and the shape `defineConnector()` parses — keeps its posture. Nothing in the runtime ever read an undeclared entry key, so no connector's behaviour moves.
+- **Read half.** The built-in `connector` redactor also withholds, on every read exit that serves a stored body through the metadata-type redactor registry: the userinfo and the credential query parameters of every URL under `providerConfig` (`baseUrl`, `transport.url`, a URL `spec`, and any other URL a provider keeps at object depth), the rest of each URL served byte for byte; and an `auth` or `authentication` value that is not an object, whole. A save of the served form keeps the stored value (the metadata protocol's carry-forward), and the runtime keeps reading the unredacted execution view.
+- `redactUrlCredentialQueryParams` (`@objectstack/spec/data`) takes an optional parameter-name list; its default, and every existing caller, is unchanged.

+// before — parsed green; neither key was read by anything
+{ name: 'billing_api', label: 'Billing API', type: 'api', provider: 'rest',
+  baseUrl: 'https://billing.example.com', apiKey: '…',
+  auth: { type: 'bearer', credentialRef: 'BILLING_API_TOKEN' } },
+
+// after — refused by name; the provider setting moves under providerConfig, the secret moves out of metadata
+{ name: 'billing_api', label: 'Billing API', type: 'api', provider: 'rest',
+  providerConfig: { baseUrl: 'https://billing.example.com' },
+  auth: { type: 'bearer', credentialRef: 'BILLING_API_TOKEN' } },
+```
+
+Set the secret under the name `credentialRef` gives (an environment variable in the open tier, or Setup → Connector credentials) and delete the key. There is deliberately no automatic rewrite: an undeclared key may be a provider setting whose home depends on the provider, or the only copy of a secret. The upgrade guide entry is `connector-entry-undeclared-key-refused`.

Measured first (2026-09-02 at `bd4aa4e49`, from `src` and through the built `dist`, identical readings): an unknown key parsed green and was DROPPED at all seven doors that reach `ManifestSchema` — the stack `manifest:` member (`defineStack` / `os validate` / `os compile`), `devPlugins[]`, the artifact `packages[]` entry in both its authoring and assembled forms, `os plugin build`, the `InstalledPackage` row schema, and the six package request/snapshot wire shapes that embed it. A transposed `namesapce` left `manifest.namespace` undefined at every one of them with exit 0 — and that key decides table names, REST paths and the install-time namespace gate (ADR-0129 D1–D2, ADR-0048 §3.2, ADR-0130 D1/D3). The same silent drop held one level down for `contributes` (`kind:` for `kinds:`), `contributes.kinds[]` and `engines` (`protocl:` for `protocol:`, which switches the load-time protocol handshake off). **The order the `api/` row records was kept: measurement, then the close.** No stored-row caller feeds this schema — `registry.validate('package' \| 'plugin')` has no live caller (`installPackage` stores the caller's object verbatim, `registerPlugin` is uncalled), the durable `sys_packages` row is re-registered through `registerApp` without a parse, and no bookkeeping key (`packageId` / `state` / `published*` / `package`) reaches any door — so the `peelStoredEnvelope` debt the `api/` row had to pay first does not exist here, and no bookkeeping key was taught to the authoring schema. Exactly ONE undeclared key was found at a real door, and it was DECLARED rather than curated: `main`, which `os plugin build` reads off the source `objectstack.plugin.json` to pick its entry and writes back into the compiled manifest as `dist/index.mjs`; three CLI fixtures author it, and a naked `strictObject` would have refused every plugin that names its entry — the shape this row would otherwise have recorded as refused. `ManifestSchema`, `contributes`, `contributes.kinds[]`, `engine` and `PluginEnginesSchema` are `strictObject` now: an undeclared key is a named rejection carrying the surface, the key and a rename (`namesapce` → `namespace`, `protocl` → `protocol`); the retired keys keep their `retiredKey()` tombstones (a tombstone types the key `never` and carries the upgrade text, which a bare refusal would not, and `acceptsNothing` keeps them out of the rename candidates); one curated wrong-layer pointer ships, `specVersion` (the retired CLI advisory axis — the live one is `engines.protocol`). `AssembledPackageBodySchema` (`stack.zod.ts`) inherits the closed posture through `.extend()`, so the load gate refuses an undeclared key on an assembled body too; that file's docblock sentence "NOT `strictObject`: `ManifestSchema` is an open object" is stale as of this change and is reported for its owner rather than edited here. Blast radius, measured with a strict preview before the close: 0 undeclared keys across the four example apps, the three `os init` templates, the `create-objectstack` blank template, the downstream-contract stack, the empty-kernel host and the i18n service manifest; the only shipped-block failure — `packages/cli/src/commands/create.ts`'s template manifest — fails the OPEN schema too (it lacks `id` and `type`) and is reported separately. Cloud is NOT MEASURED for this file (no checkout in the container, code search refused); if cloud parses a published `.osplugin` manifest through this schema, the compiled manifest it receives carries only declared keys (`main` and `integrity` included) by construction of `os plugin build`. The rest of `kernel/` is unchanged: plugin/kernel contracts, code-to-code |

+| `integration/` | **mixed · `connector.zod.ts`'s declarative entry authorable, the rest wire** | ⚠️ **Split at the connector-entry close — the flat `wire` verdict this row carried was right for the payloads and wrong for one shape, the `api/` and `kernel/` rows' finding again.** `DeclarativeConnectorEntrySchema` is the `connectors:` stack collection and the `connector` row the metadata save door keeps (`PUT /api/v1/meta/connector/:name`, bound in `UNREGISTERED_KIND_SCHEMAS`, which stores the request body for every type but `view` — ADR-0005 appendix (c), ruling B): an AUTHORED, STORED, SERVED type, not an upstream payload, yet it was a plain `z.object`, so an undeclared top-level key parsed green at every door that reads it. It is closed through a dedicated `strictObject` carrier (`DeclarativeConnectorEntryBaseSchema`) built from the same shape factory as the open one, each with its own field instances so `computeGuidanceRoutes()` never pairs the open `Connector` def with the closed declaration's `guidance`. Every door that parses the entry — `defineStack({ connectors })`, `os validate` / `os compile`, the artifact load at boot and reload, and the save door (`422 INVALID_METADATA`) — refuses the key by name, located at it; two curated families ride the refusal: credential-shaped keys → `auth.credentialRef`, provider settings → `providerConfig`. The ADR-0010 envelope was already declared on the shape (commit b5404f496), so no stamped entry is refused. Governing texts read before the close: ADR-0097, ADR-0143, ADR-0104 and the type-schema suite's #2657 fence — none keeps the authored entry open; the `ConnectorSchema is NOT .strict()` sentences across `connector.zod.ts` state the fact that made each retirement a `retiredKey()` tombstone, not a decision to stay open. ⛔ Deliberately NOT closed: `ConnectorSchema`, the def a plugin hands to `registerConnector` (code-to-code — the wire half of this row) and the shape `defineConnector()` parses, so `defineConnector({ … })` still drops an undeclared key before the entry sees it; closing that carrier is its own decision.

It was found instead by driving the gate's own instrument (`computeGuidanceRoutes()` in `scripts/build-schemas.ts`) over every emitted def: match each def to its declaration, then ask the def what it actually does with the key. Census on `42f8df1723`: 1527 emitted defs, 258 resolving to exactly one declaration, 779 keys promised, **770 delivered, 9 not** — 2 of them this live silent strip, the other 7 union defs whose discriminator the probe's one-key document cannot supply (they DO deliver to an author who writes a whole document). The close moves the strictness and both tables onto the shared schema, leaving ONE declaration and ONE door for both defs: 772 delivered, 7 not. ⚠️ The residual 7 are a PROBE boundary, ⛔ not a clean zero and ⛔ not a finding. ⚠️ **Annotated at #16845 — the flat `n/a` verdict this row carried was right for the directory and wrong for one file in it, the `api/` and `kernel/` rows' finding a third time.** — the flat `n/a` verdict this row carried was right for the directory and wrong for one file in it, the `api/` and `kernel/` rows' finding a third time.** ⛔ **This directory is still UNTRIAGED and this is not a per-file row** — `shared/` has never had per-file rows, so `shared/protection.zod.ts` was **never enumerated** by this campaign; it was not deliberately accepted, because no verdict was ever taken on it. Two measurements say why the silence carried no information. **①** This row's own rationale — *strictness decided at the consuming schema* — is false for this file: all **16** `protection: ProtectionSchema` mounts across **14** files are the bare `ProtectionSchema.optional()`, not one `.extend()` / `.merge()` / `.omit()` / re-posture among them, so both the strictness and the MESSAGE are decided here in `shared/` and inherited verbatim by objects, views, dashboards, datasets, reports, apps, flows, webhooks, permissions, positions, email templates, agents, tools and skills — very nearly every authorable metadata type in the platform. A row is read as licence, which is what this ledger's own gate exists to prevent. **②** Even a per-file row would not have surfaced the defect, and this is the part worth keeping: `ProtectionSchema` has been `.strict()` since it was introduced, so it counts in the `strict` column and could never carry a remaining-strip row. **This ratchet's axis is CLOSURE; the defect was MESSAGE QUALITY** — a closed shape with no error map, refusing `lockk` with zod's bare `Unrecognized key: "lockk"`: no surface, no declared-key list, no rename, on every one of those mounts. `strictObject` at #16845 (the `PluginPermissionsSchema` conversion at #16328 one directory over is the precedent). ⛔ The population of *closed shapes still carrying zod's bare message* is **NOT MEASURED** here and is not this row's claim — #14722's rule stands that a sweep needs its own card with its own measured count. The rest of `shared/` is unchanged: utilities and building blocks whose strictness really is decided at the consuming schema |
