# List responses

> Returns responses for a workspace, newest first. Session cookie, `x-api-key`, or a Bearer token, with read access.

**Scoping.** `workspaceId` is required, as on every v3 collection read. Add `surveyId` to narrow to one survey — the common case, and the one the storage layer is indexed for (`(surveyId, createdAt)`). A workspace-wide list has to reach responses through their surveys and is correspondingly slower, so pass `surveyId` whenever you know it. `contactId` narrows to one respondent.

**Pagination is keyset**, on `(createdAt, id)`. The `cursor` is opaque and bound to the sort order and the filter set it was issued for; changing either invalidates it. `meta.nextCursor` being `null` is the only end-of-collection signal — do not infer the end from a short page.

`id` is there purely as a tie-breaker, and it makes the order **total**, so no row is ever skipped or repeated across pages. What it is not is a finer-grained clock: `createdAt` is stored to millisecond precision, so responses sharing a millisecond — everything written in one bulk insert, for instance — come back in an order that is stable and repeatable but is not their true creation order. Do not read the sequence within a millisecond as meaningful.

**Filters are allow-listed**, and each one on its own is either served by an index or bounded by one. `filter[finished][eq]` and `filter[language][in]` additionally require `surveyId` or `contactId`, because both are heap residuals that are only bounded when the scan is anchored to one survey or one contact; sending either without such a scope returns **400**.

Be aware that **combining** a `filter[createdAt]` bound with `filter[finished][eq]` is the one case no single index covers: the ordered scan uses `(surveyId, createdAt)` and `finished` stays a heap residual, so a page whose matches are sparse reads far more rows than it returns. Prefer narrowing by `surveyId` and a tight `createdAt` window, and treat that combination as the slow path until a covering index exists.

**What this endpoint deliberately does not filter on:** individual answers, hidden-field values, submission metadata (`source`, `url`, `country`, `browser`, `os`, `deviceType`), contact attributes, quotas, and tags. Each is a JSON path or an unindexed join on the largest table in the database, where the honest outcome is a timeout rather than a slow query. The in-app dashboard does offer these, so this endpoint is knowingly behind it; closing the gap needs index work and is tracked separately rather than quietly omitted.

    Authenticate all management endpoints with **session cookie** or
    **`x-api-key`** (management key with access to the workspace).


    **Spec location:** source of truth is the multi-file tree at
    `docs/api-v3-reference/src/` (root `openapi.yml` plus one file per path and
    component); `docs/api-v3-reference/openapi.yml` is the generated single-file
    bundle (alongside v2 at `docs/api-v2-reference/openapi.yml`).


    **workspaceId**

    `workspaceId` is the canonical container identifier for this API. It is a
    **required query parameter on collection read endpoints** (`GET
    /api/v3/surveys`, `GET /api/v3/action-classes`, `GET
    /api/v3/contact-attribute-keys`) because those operate within a workspace.
    **`POST /api/v3/surveys` instead requires `workspaceId` in the request
    body**, not as a query parameter. Single-resource endpoints
    (`GET`/`PATCH`/`DELETE /api/v3/surveys/{surveyId}`) locate the resource by
    its globally-unique id and resolve the workspace from it, so they do **not**
    accept a `workspaceId` query parameter — sending one returns **400** with an
    `invalid_params` entry naming the key itself (`name: "workspaceId"`,
    `reason: "Unsupported field 'workspaceId'"`), rather than one naming the
    body.


    **Auth**

    Authenticate with either a session cookie or **`x-api-key`**. In dual-auth
    mode, V3 checks the API key first when the header is present, otherwise it
    uses the session path. Unauthenticated callers get **401** before query
    validation.


    **Pagination**

    Cursor-based pagination with **limit** + opaque **cursor** token. Responses
    return `meta.nextCursor`; pass that value back as `cursor` to fetch the next
    page. Survey list responses also include `meta.totalCount`, the total number
    of surveys matching the current filters across all pages. Workflow list
    responses do not require total counts in Scope 1. There is no `offset` in
    this contract.

    The page-size **maximum is 250** for responses, surveys, action classes and
    contact attribute keys; only the *default* varies by resource (20 for
    surveys, 50 for the workspace reference lists). **The workflows and
    workflow-run lists remain at 100** — their bound lives in the
    `packages/workflows` contracts and moves with that package, so each
    documents the value it actually enforces. A `limit` above an endpoint's
    maximum is rejected with **400** rather than silently reduced, consistent
    with v3 rejecting unrecognized query parameters instead of ignoring them.
    Callers should not infer the end of a collection from a page shorter than
    `limit`; `meta.nextCursor` of `null` is the only end-of-collection signal.
    Note that array-valued *input* bounds are a separate concern and stay at 100
    — `filter[id][in]` and the batch-delete id list are bounded by write and
    payload risk, not by page cost.


    **Strictness**

    A query parameter that an operation does not declare returns **400**, with
    the offending key reported in `invalid_params[].name` — including on
    operations that declare no query parameters at all. Unknown parameters are
    rejected rather than ignored on purpose: a silently-dropped filter returns
    *more* data than the caller believes they asked for, and a typo in a filter
    name is indistinguishable from no filter at all. The same applies to request
    bodies, where unsupported fields are rejected instead of stripped.

    Unrecognized **headers** are tolerated, as gateways and proxies legitimately
    add them; strictness is about parameters and body fields, not transport
    metadata.

    This is the rule for the surveys, responses, tags and workspace
    reference-list operations. The workflows family does not enforce it today,
    so treat parameter strictness there as unspecified rather than guaranteed.

    **Request limits**

    A request body may be at most **2 MB**; a larger one is refused with **413**
    before it is read. Inside a body, **no array may hold more than 1 000 items,
    and all arrays together may hold at most 50 000 elements**, at any depth — a
    body that exceeds either bound is refused with **400** and a single
    `invalid_params` entry naming the offending array, before any field is
    validated. The same holds for nesting: a body may nest at most **256**
    levels of objects and arrays, counted from the root, and a deeper one is
    refused the same way, naming where it went too deep. Fields with a tighter
    bound document it as `maxItems` on the field (a survey's `blocks`,
    `endings`, `variables`, `languages`, `hiddenFields.fieldIds` and
    `distribution.triggers` since 0.2.0). A 400 or 422 lists at most **50**
    `invalid_params` entries; when there are more, the last entry says how many
    were left out. Since 0.2.0.

    **Filtering**

    Filters use explicit operator-style query parameters under the
    **`filter[...]` family**. The survey list supports `filter[name][contains]`,
    `filter[status][in]`, and `filter[type][in]`. The workflow list supports
    `filter[name][contains]` and `filter[status][in]`; the workflow run list
    supports `filter[status][in]` and `filter[isDryRun][eq]`. Resource-scoping
    identifiers (`workspaceId`, `workflowId`, `responseId`) stay plain query
    parameters. Multi-value filters use repeated keys or comma-separated values
    (e.g. `filter[status][in]=draft&filter[status][in]=inProgress` or
    `filter[status][in]=draft,inProgress`). Sorting remains a flat `sortBy`
    query parameter.


    **Responses**

    The response resource is **self-describing**. Answers come back as a typed
    `answers[]` array in which each entry carries the element's id, label, type
    and value, rather than as a map keyed by element id — so a consumer holding
    only a response can read it without fetching the survey and joining. Hidden
    fields, survey variables and auto-captured context are one `embeddedData[]`
    collection rather than three parallel concepts, each entry declaring a
    `kind` and a `type`. Data whose element has since been deleted is reported
    in `unresolved[]` instead of being dropped silently. Labels are resolved at
    read time against the current survey definition, and the `resolution` object
    discloses that policy along with the survey's `updatedAt` so a consumer can
    detect wording drift.

    Writes take answers in the **stored map form** (`data`) while reads return
    the typed array. Resolving ids into labelled answers is unambiguous; the
    reverse would mean matching caller-supplied labels back onto option ids, so
    the write side keeps the stored shape. To stop that costing
    round-trippability, the **detailed read returns `data` unchanged** — so a
    single-response read can be edited and sent back as `PATCH { "data": … }`,
    and the typed `answers[]` array is an addition rather than a replacement.


    One case where that round trip does not close: a write bound applies to
    `data` on the way in (`ResponseDataMapInput`) and none applies to the stored
    map, because v1 and v2 wrote it without one. A response carrying more answer
    keys than the write accepts therefore cannot be corrected through `PATCH` at
    all — the whole map is rejected, and sending a smaller one is not a
    workaround, because `data` is replaced wholesale and every key left out is
    deleted. Correct those through the v1/v2 management API or the dashboard.
    This is reachable only on surveys with more elements than the bound allows.

    Embedded Data is the exception, and it is symmetric rather than
    round-tripped: hidden fields and variables are read and written through
    `embeddedData`, addressed by **name** in both directions. No raw map of them
    is echoed, because a name is already what a write accepts — publishing the
    storage keys underneath (a variable's is its cuid) would expose a layout the
    caller has no use for. `data` therefore carries element answers only.

    Of those two, only `data` carries no `readOnly`, because it is the same map
    on the way in and on the way out. Embedded Data is writable through the
    **request's own** `embeddedData` map, not through the response field of that
    name — so `embeddedData[]`, like every other derived view on the resource,
    is marked `readOnly`, per its meaning of server-managed. `ResponseResource`
    lists them all. The list view omits `data`, since a bulk reader is not
    editing. `POST /api/v3/responses/validate` exists so a caller can see what a
    map would produce, and what a write would do, before committing to it.

    `createdAt` and `updatedAt` are **server-owned** on this resource: they
    cannot be supplied on create or changed by a patch. Response metering counts
    rows by `(surveyId, createdAt)`, and a client-chosen `createdAt` also lets
    rows be inserted into the middle of another consumer's already-paginated
    stream. Backdating stays available on v2 until a dedicated import path
    exists. The respondent's IP address and the `contactAttributes` snapshot
    that v1/v2 expose are not part of this resource in any view; that snapshot
    is copied from the contact at submission time and never refreshed, so it is
    stale PII by construction.

    Response filtering is allow-listed and index-backed:
    `filter[createdAt][gte|gt|lte|lt]` (at most one lower and one upper bound —
    `gte` xor `gt`, `lte` xor `lt`), `filter[finished][eq]`,
    `filter[language][in]` and `filter[id][in]`. `filter[finished][eq]` and
    `filter[language][in]` require `surveyId` or `contactId` as well, because
    both are heap residuals bounded only by an anchored index range. Per-answer,
    hidden-field, submission-metadata, contact-attribute, quota and tag filters
    are **not** offered; each is a JSON path or an unindexed join on the largest
    table in the product. The in-app dashboard does offer them, so this API is
    knowingly behind the dashboard here — closing the gap requires index work
    and is tracked separately rather than quietly omitted.

    `GET /api/v3/responses/count` answers "how many match?" directly. The list
    endpoint's `meta.totalCount` covers a caller that is already paging and is
    **opt-in** via `includeTotalCount` (default `false`, unlike the survey list)
    because responses are the highest-cardinality table in the product. Both
    response counts are **capped at 10 000** and carry an exactness flag —
    `meta.totalCountRelation` on the list, `data.relation` on `/count` — reading
    `eq` when the figure is exact and `gte` when the cap was reached and it is a
    lower bound. An exact count over this table grows superlinearly with the
    data while a capped one stays flat, so an uncapped total would be the only
    part of a response whose cost is unbounded. `/count` accepts
    `precision=exact` for the cases that genuinely need a precise figure,
    documented as the deliberate slow path. The survey list's `totalCount` stays
    exact and uncapped: surveys are low-cardinality and that count has a
    covering index built for it.

    Bulk deletion is `POST /api/v3/responses/batch-delete`, a custom method
    rather than a collection-level `DELETE`, so a call that loses its filters
    cannot degrade into erasing everything in scope. It scope-filters rather
    than rejecting: foreign and already-deleted ids are ignored and the call
    reports how many rows it removed, which keeps it both leak-free and safe to
    retry.

    **Security**

    Missing/forbidden workspace returns **403** with a generic message (not
    **404**) so resource existence is not leaked. Workflow and workflow-run
    detail endpoints also return **403** for unknown IDs or inaccessible IDs to
    avoid IDOR leaks. List responses use `private, no-store`.


    **AI survey creation**

    `POST /api/v3/surveys/generate` returns a draft `POST /api/v3/surveys`
    payload plus validation metadata. It does not create a survey. It generates
    survey content for both `link` and `app` surveys; for `app` it seeds a
    default `distribution` (display once, no triggers, no targeting) that you
    finish configuring before publishing.

    Prompt text is sent to the configured AI provider for generation, but it is
    not stored by this endpoint, not logged by default, and not included in
    audit data.


    **Feedback Records** `/api/v3/feedbackRecords` is served by the **API
    gateway** (Envoy on Formbricks Cloud, Traefik in the one-click Docker
    install), which authorizes each call against the dataset and forwards it to
    the feedback store — not by the application routes that serve the rest of
    v3. Three consequences: the payload is the store's own, so members and
    filters are **`snake_case`** (`tenant_id`, `value_text`) rather than v3's
    camelCase; the dataset is named **`tenant_id`** on the wire and is required
    on every collection operation (it is the feedback dataset id, which the MCP
    `list_feedback_datasets` tool reports as `dataset_id`); and errors come in
    two shapes — gateway refusals (**400**, **401**, **403**, **413**, **503**)
    are `text/plain`, while the store's own problems are
    `application/problem+json` with a stable `code`. These eight operations are
    the whole of the gateway-served surface; any other path it receives under
    the prefix answers **400**. Authenticate with **`x-api-key`**: the key needs
    a permission on a workspace the dataset is assigned to — `read` to list, get
    and search, `write` to create and update, `manage` to delete — and may
    update or delete only in a dataset assigned to exactly one workspace.

    **OpenAPI**

    This spec is **not** produced by `pnpm generate-api-specs` (that script only
    builds v2 → `docs/api-v2-reference/openapi.yml`). When the route contract
    changes, edit the files under `docs/api-v3-reference/src/`, then run `pnpm
    api:v3:bundle` to regenerate the committed single-file bundle. `pnpm
    api:v3:lint` lints the source tree; `pnpm api:v3:check` (CI) fails when the
    bundle is stale.


    **Workflows Scope 1**

    Workflows are a follow-up extension of the existing v3 Survey API work. The
    Survey API establishes API-first survey authoring; Workflows build on that
    same v3 style to automate actions around survey responses through
    workspace-scoped JSON definitions. Scope 1 models the existing Follow-ups
    capability as workflows: one `response.completed` trigger with an optional
    `endingCardIds` filter, and `send_email` actions with Follow-up email field
    parity. The definition and run shapes mirror the shared Zod schemas in
    `packages/workflows` (ENG-1100), which are the implementation source of
    truth for this contract.


    Workflows use `draft`, `enabled`, and `disabled` lifecycle states plus an
    `archived` soft-delete state. Status only changes through the lifecycle
    endpoints (`enable`, `disable`, `archive`, `unarchive`); it is not writable
    via `POST` or `PATCH`. Enabling validates that the definition is executable
    and snapshots an immutable workflow version; runs reference that snapshot
    via `workflowVersionId`. `POST .../test` is a dry run: it validates the
    definition and resolves the trigger's references synchronously, creating no
    run and sending no email, and returns `{ workflowId, ok, problems }`
    directly. Real runs execute asynchronously and are polled via `GET
    /api/v3/workflows/runs/{runId}`.


    **Overview migration note**

    The v3-backed survey overview page intentionally removes actions that are
    not yet exposed by this contract: `Created by` filtering, `Duplicate`,
    `Copy...`, `Preview`, and `Copy link`.


    **Next steps (out of scope for this spec)**

    Optional ETag/304, field selection, translation-specific writes, and survey
    version history.

      summary: List responses
      description: >
        Returns responses for a workspace, newest first. Session cookie,
        `x-api-key`, or a Bearer token, with read access.


        **Scoping.** `workspaceId` is required, as on every v3 collection read.
        Add `surveyId` to narrow to one survey — the common case, and the one
        the storage layer is indexed for (`(surveyId, createdAt)`). A
        workspace-wide list has to reach responses through their surveys and is
        correspondingly slower, so pass `surveyId` whenever you know it.
        `contactId` narrows to one respondent.


        **Pagination is keyset**, on `(createdAt, id)`. The `cursor` is opaque
        and bound to the sort order and the filter set it was issued for;
        changing either invalidates it. `meta.nextCursor` being `null` is the
        only end-of-collection signal — do not infer the end from a short page.


        `id` is there purely as a tie-breaker, and it makes the order **total**,
        so no row is ever skipped or repeated across pages. What it is not is a
        finer-grained clock: `createdAt` is stored to millisecond precision, so
        responses sharing a millisecond — everything written in one bulk insert,
        for instance — come back in an order that is stable and repeatable but
        is not their true creation order. Do not read the sequence within a
        millisecond as meaningful.


        **Filters are allow-listed**, and each one on its own is either served
        by an index or bounded by one. `filter[finished][eq]` and
        `filter[language][in]` additionally require `surveyId` or `contactId`,
        because both are heap residuals that are only bounded when the scan is
        anchored to one survey or one contact; sending either without such a
        scope returns **400**.


        Be aware that **combining** a `filter[createdAt]` bound with
        `filter[finished][eq]` is the one case no single index covers: the
        ordered scan uses `(surveyId, createdAt)` and `finished` stays a heap
        residual, so a page whose matches are sparse reads far more rows than it
        returns. Prefer narrowing by `surveyId` and a tight `createdAt` window,
        and treat that combination as the slow path until a covering index
        exists.


        **What this endpoint deliberately does not filter on:** individual
        answers, hidden-field values, submission metadata (`source`, `url`,
        `country`, `browser`, `os`, `deviceType`), contact attributes, quotas,
        and tags. Each is a JSON path or an unindexed join on the largest table
        in the database, where the honest outcome is a timeout rather than a
        slow query. The in-app dashboard does offer these, so this endpoint is
        knowingly behind it; closing the gap needs index work and is tracked
        separately rather than quietly omitted.

            a lower bound (`gte`). If all you need is the count, use `GET
            /api/v3/responses/count` rather than fetching a page to get it — and
            if you need an exact figure beyond the cap, that endpoint takes an
            explicit `precision=exact`.

        `answers[]` and `embeddedData[]` ship on the list view as well as the
        detailed view — they are the point of the resource, and withholding them
        from the list would force consumers into an N+1 of item reads. The list

                which `totalCountRelation` states explicitly. `null` unless
                `includeTotalCount=true`.


                The cap is not timidity — an exact count over this table grows
                superlinearly with the data while a capped one stays flat, so an
                uncapped total is the one part of a page whose cost is
                unbounded. Read `totalCountRelation` rather than testing for the
                magic number.

                `includeTotalCount=false`. This is the same eq/gte convention
                Elasticsearch uses for `hits.total.relation`, so a consumer can
                render "10,000+" honestly instead of claiming a precise figure
                it does not have.

        problem sets `type`, so per RFC 9457 §4.2.1 `title` is always the HTTP
        reason phrase for `status` and carries no information of its own.


        Member naming is frozen as published, mixed conventions included
        (`requestId` alongside `invalid_params` and `details.resource_type`):
        renaming any of them would break every client that reads them.

            Summing rather than reading `_total` is deliberate: the stored
            bucket is only written when a response is finished, so reading it
            would leave every partial response without a duration even when it
            carries per-element timing. This is also why the value can differ
            from the reserved `durationSeconds` catalog entry, which does read
            the bucket and rounds to whole seconds — that entry is not projected

        sibling branch's properties as additional and rejects them. An endpoint
        that adds nothing still wraps it, so no `meta` anywhere is open.


        Every field here is `required`. A shared envelope that makes its fields
        optional is how v3's predecessor stopped honouring its own pagination
        contract without the schema gate noticing (ENG-2622): `meta: {}` — or no
        `meta` at all — validated cleanly while the endpoint returned nothing.

            This is the shared error shape every v3 operation returns, so it
            lists what the API can emit today and nothing more —
            `INVALID_PARAM_CODES` in `app/api/v3/lib/response.ts` is the
            registry, and a code absent from it is dropped before the response
            is built. Categories for operations that do not exist yet are added
            with the code that emits them, not ahead of it.


            `qsf_not_recognized` and `qsf_limit_exceeded` come from the
            Qualtrics import (an internal, session-only route sharing this
            shape): the file is not a Qualtrics export it can read, or it is one

            never have seen. Typeform, SurveyMonkey, Qualtrics, Google Forms and
            Jotform all behave this way, so this is the industry norm rather
            than a shortcut. Compare `surveyUpdatedAt` against the response's

        One answer, carrying the element's id, its label, its type and its
        value. `elementType` selects the shape: switch on it rather than probing
        for which value field is present.


        Answers are a **typed array**, not a map keyed by element id, because a
        consumer holding only a response would otherwise see bare ids and have
        to fetch the survey and join to learn what was asked — a join that is
        easy to get wrong and that agent clients cannot make cheaply. The array
        also separates answers from hidden fields and variables, which the
        stored representation mixes into one flat map. Non-answer data lives in
        `embeddedData[]`.


        Several element types share a value shape and therefore a schema — the
        four numeric scales, the four choice styles, the two composites. All
        seventeen element types are covered.


        Only elements the respondent actually reached appear here. Data whose
        element has since been deleted appears in `unresolved[]` instead.
    ResponseEmbeddedDatum:
      type: object
      description: >
        One piece of non-answer data carried by the response. Survey
        **variables**, **hidden fields** and **auto-captured context** are one
        concept here rather than three parallel ones: they all have a key, a
        provenance, a declared type and a label, and consumers treat them alike.


        Auto-captured (`reserved`) entries are drawn from the Embedded Data
        field catalog, which declares a privacy policy per field (`keep` /
        `drop` / `redactQuery`). Two of those act **before** this API sees the
        response, and one is a rule this API adds:


        - `drop` is an **ingest-time** policy, not a filter applied here: when
        the survey has "Anonymize
          responses" enabled the field is never captured, so it is absent from the response for every
          consumer. With anonymization off it is captured and appears here normally.

        - `redactQuery` is applied on **every** read, anonymization or not —
        `url` and `pageReferrer` carry
          their query string stripped.

        - `ipAddress` is **never** projected by this API, in any view. That is a
        v3 rule rather than a
          catalog behaviour: the catalog reads the field, and the dashboard shows it. Do not infer the same
          suppression for the other `drop` fields.


        Where a survey's own field and a catalog entry share a name, both appear
        — the declared one as `ingested` or `computed`, the auto-captured one as
        `reserved` — and `kind` is what tells them apart. Neither shadows the
        other, because each is a real value the response carries and dropping
        one would hide data the author can see elsewhere.


        Which catalog entries appear at all is a third axis, `display`, and this
        collection carries the ones that are not `none`. The `none` set is the

            Not the storage key. A hidden field happens to be stored under its
            name and a variable under its cuid, and that split is a property of
            the storage layout rather than of the field; exposing it would
            publish an internal id and make the writable and readable views of
            one field disagree on how to address it.


            **Unique per `kind`, not across the collection.** A survey created
            before the reserved names were enforced can declare a hidden field
            called `country`, and the auto-captured `country` still exists — so
            the same name can appear once as `ingested` and once as `reserved`.
            That set is finite and no longer growing: a new declaration may no
            longer take a reserved name, or the name of a variable or hidden
            field the survey already has. Key on `(key, kind)` rather than `key`
            alone, or read the pair you care about.

            - `computed` — derived during the submission by survey logic
            (variables).

            - `reserved` — auto-captured context from the submission environment
            (for example `country`,
              `deviceType`), drawn from the Embedded Data field catalog.

            Always a scalar. A legacy row can hold an array or an object under a
            declared field's key — the ingest contract refuses those now, but
            older rows have them — and such a value resolves to nothing rather
            than being coerced, so the entry is omitted here and reported in
            `unresolved[]` with the bytes intact. Nothing is silently dropped,
            and no `type` would describe an array anyway.


            There is no `null` member: a declared key that resolves to nothing
            is **omitted** from the collection rather than carried with a null.
            So `embeddedData[]` enumerates what the response actually holds, not
            what the survey declares — a survey with twelve declared fields and
            two filled in yields two entries. A field with a default value is
            never unset, since the default is the fallback before the key is
            considered missing.

    ResponseUnresolvedEntry:
      type: object
      description: >
        Stored data that nothing in the current survey definition can account
        for. Deleting an element, a hidden field or a variable leaves its values
        behind on already-collected responses and nothing cleans them up, so the
        payload reports them here instead of dropping them silently or faking
        them into `answers[]` without a type or a label. Consumers doing
        analysis can ignore this array; consumers doing export or migration
        should not.


        **A declared field's `defaultValue` takes precedence over anything
        unreadable stored under its key**, and that is worth stating because
        this collection otherwise reads as exhaustive. Resolution falls back to
        the default before a value is ever judged unreadable, so a field that
        declares one always resolves — and the stored bytes, whatever their
        shape, are reported nowhere. Only a field with **no** `defaultValue` can
        reach `valueShapeMismatch`.

        A **scalar** under a defaultless field is not reported either, and the
        cause is the reporting guard rather than `locked`. Only
        `resolveEmbeddedValue` consults the lock; the guard that decides what
        reaches this collection admits objects only. So an uncoercible scalar —
        `"yes"` under a boolean field — resolves to nothing and is then excluded
        for being a scalar, lock or no lock. A non-scalar under a lockless,
        defaultless field is what does reach `valueShapeMismatch`. Neither
        omission is a silent drop by accident — one follows from resolution
        order, the other from the reporting guard — and both are written down so
        a consumer does not read `unresolved[]` as a guarantee that nothing was
        left behind. If either proves to matter in practice a reason code can be
        added without breaking anyone, whereas removing one could not — which is
        why this is documentation rather than a guess at a fifth enum member.

            Why the entry could not be resolved:


            - `elementNotInSurvey` — nothing in the current definition claims
            this key. It covers a deleted
              element **and** a deleted hidden field, because the two cannot be told apart: an answer is
              stored under its element id and a hidden field under its name, in one shared map, and storage
              keeps no record of which kind a vanished key used to be.

            - `variableNotInSurvey` — no variable with this id exists in the
            current definition. Variables
              *are* distinguishable, because they live in their own map keyed by cuid rather than sharing
              the answer map.

            - `valueShapeMismatch` — the key resolves to a current element **or
            a declared Embedded Data
              field**, but the stored value's shape cannot be read as an
              answer of that element's type (for example a string where the element expects a selection
              list). Signals element-type churn rather than deletion.

                A deliberate choice between two things this field could be.
                Storage writes a relative path and the app's own read paths
                rewrite it to an absolute URL for display; v3 returns the stored
                bytes instead, because `answers[]` promises verbatim values a
                client can write straight back, and an absolute URL is neither
                what is stored nor what a write accepts. Fetching a file is a
                separate concern with its own ticket (ENG-513, signed
                short-lived URLs behind a dedicated endpoint); this field
                identifies the file, it does not serve it.


                Not publicly fetchable in any case: access follows the same
                authorization as the response, and deleting the response deletes
                the underlying files.

            The bounds hold on **every** row, including ones collected before
            the write-side clamp shipped. The stored representation is
            deliberately unbounded so that historical data still parses, and a
            row written then can hold a negative value or a tab left open for
            days; those are clamped into range on read rather than returned
            as-is, because a schema a real row violates is worse than a slightly
            blunted outlier. So `86400` means "at least 24 hours", not exactly.

        definition.

        - `label` — the stored value matched an option's **label text** (ids are
        stable, labels are
          editable and language-dependent, so a label match is weaker evidence).

        - `other` — the value arrived through the element's **Other** free-text
        input. Only reported when
          the element actually has that input enabled and the value was submitted through it.

        - `unmatched` — no option resolves. The raw value is still returned; it
        is **not** silently
          reclassified as `other`, because a *renamed* option is also unmatched text and filing it as a
          write-in would misattribute the answer.
