        "description": "Save and reuse evidence in an authorized Recoup workspace. **Preview: this reference is verified against API source, not a completed hosted acceptance test.** Actions require the corresponding database and workflow release; verification actions also require their feature to be enabled. Do not infer provider readiness, complete coverage, or a successful workflow from an accepted request schema.\n\n### Create context\n\n`ingest` creates or reuses a Spotify-track request and dispatches its durable workflow (202). The parser recognizes YouTube URLs, but ingestion still rejects them in this pilot. `ingest_release` stores a Spotify album locator; it does not automatically verify the release. `ingest_catalog` and `ingest_artist` refer to accessible Recoup records. `ingest_songwriter_name`, `ingest_company_name`, `ingest_campaign_brief`, and `ingest_supporting_text` store submitted context (200). Names and customer text are not verified identities or facts. Reuse an idempotency key only for the same intended input.\n\n### Read, plan and inspect\n\n`read` reads one request. For saved supporting text, HTTP and standard MCP also return a metadata-only `material_evidence` receipt identifying the current document, result and exact retained source version. It returns no submitted text, source location or signed access. `draft_origin` remains `not_recorded`: a retained customer assertion is not proof of its file origin or reviewed business facts. Unavailable material withholds those references. Delegated OAuth keeps its request-only response. `plan` plans modules from stored context; a plan is not authorization to collect data. `list_executions` and `read_execution` expose execution records. `list_catalog_members` pages saved members; `expand_catalog_members` materializes a bounded member page. These operations return 200. Request IDs, subject IDs and execution IDs refer to different records; use the IDs returned by the corresponding read rather than substituting an account ID. Catalog membership does not establish rights ownership. Use `plan_catalog_members` to plan a lookup for a page of current expanded catalog recordings, as described below.\n\n### Plan a catalog lookup\n\nA catalog manager can inspect which lookup would be proposed for recordings already expanded from an accessible catalog. This action reads the saved targets and returns a plan; it does not fetch recording matches, linked works or platform information.\n\nSupply the existing catalog Context `request_id` and its catalog `subject_id`, one `module`, and optionally `organization_id`, `after_isrc` and `limit` (1–100, default 100). These IDs refer to different records: do not substitute the catalog ID, account ID or a member recording subject for the catalog Context subject.\n\n| Preferred input | Lookup being planned | Legacy accepted input and returned module |\n| --- | --- | --- |\n| `recording_candidates` | Unconfirmed recording candidates from an ISRC; a candidate is not an approved recording identity | `musicbrainz` |\n| `recording_work_candidates` | Candidate works linked to a recording; no ownership or royalty-share verification | `mlc_recording` |\n| `platform_metadata` | Available platform track information; no growth-metric or complete-coverage promise | `songstats` |\n\nAll six input values remain accepted. The three values in the last column are compatibility identifiers, not a promise that data sources are interchangeable. Each preferred/legacy pair returns the same page, raw module, executor, node key, state and reasons. Source and saved-plan provenance remain unchanged.\n\nThe 200 result is `ContextCatalogPlanningResponse`: `page`, `plan` and `collectionPermitted: false`. `page` includes `catalogId`, `catalogSubjectId`, `members`, `nextCursor` and `hasMore`. Each member retains `subjectId`, `kind`, `identityConfirmed`, `availableFields`, `reusableModules` and `isrc`. The saved ISRC-backed target flag does not verify an external recording match, rights or ownership. Only expanded recordings still present in the selected workspace's accessible catalog are returned; removed and not-yet-expanded members are excluded. Pass `page.nextCursor` as `after_isrc` when `page.hasMore` is true.\n\n`plan` has one node per returned member, including `key`, `entry`, `subjectId`, `targetKind`, `module`, `executor`, `state`, `reasons`, `dependsOn`, `scope` and `executionStarted`. Node keys retain `{subjectId}:{legacy_module}`. This action supplies no permitted modules and does not reuse collection permission: every returned node is `blocked`, has `executionStarted: false`, an empty `dependsOn` and the reason `Server collection policy has not permitted this module`. An empty member page returns `plan: []` and still has `collectionPermitted: false`.\n\nAn executor name describes a planned implementation; it does not make that collector runnable. In particular, the platform-metadata collector is not connected to the trusted planned dispatcher. No provider/model call, execution claim, credit charge, new access grant or automatic catalog expansion is triggered. An accepted request or local fixture is not hosted customer-workflow acceptance.\n\n### Release verification and review\n\n`verify_release` and `verify_release_tracks` enqueue enabled verification workflows (202); disabled features or unmet readiness conditions return 409. `list_release_tracks`, `read_release_track_observations`, and `review_release_track_identities` inspect saved slots and identity evidence (200). Inspect the returned readiness, coverage and unresolved identity state before using a recording match. `list_release_cases`, `read_release_case`, `read_release_case_review`, and `review_release_case` read or record release-case review. A review requires the current fingerprint, a decision, and an idempotency key; it does not silently rewrite source evidence.\n\n### Compile and save briefs\n\n`brief` compiles evidence from up to ten completed or partial requests in one workspace without provider or model calls. Purposes are `creative_direction`, `playlist_pitch`, and `company_onboarding`. Creative direction prioritizes lyrics and artwork; playlist pitching prioritizes catalog/audio metadata. Inspect readiness, request_coverage, selected input versions and gaps. Briefs are evidence packets, not finished creative concepts or outreach. Compiled documents have accepted status and full or partial coverage; creative proposals and other document states are excluded by the current selector. Accepted is a saved-evidence status, not verification of identity or rights. `save_brief` freezes the server-compiled output, and `read_brief` retrieves that snapshot without recompilation. Newer evidence can supersede a snapshot without rewriting it; withdrawn evidence or removed scope can withhold its payload. All three actions return 200.\n\n#### Evidence retrieval dates — pending API release\n\nThis addition is documented against [API #1003](https://github.com/recoupable/api/pull/1003), reviewed source `4212e41b62e56fd68deb9edbed7bcd09773b18bf`. It is pending the coordinated API release; these schemas and synthetic examples do not establish deployed availability.\n\nNew compilations include `input_manifest.freshness`, also retained inside a newly saved snapshot's `brief`. The field remains optional in response schemas so older saved snapshots may omit it. `read_brief` returns the saved output without recompiling or backfilling freshness. `compilerVersion` stays `context-brief-v1`, and each `input_manifest.documents[]` entry retains its existing six fields.\n\nWhen `freshness` is present, all four fields are required: `oldestRetrievedAt` and `newestRetrievedAt` are UTC timestamps or `null`; `documentsWithoutRetrievalDate` lists selected document UUIDs with no usable retrieval date; `documents` gives each selected document's UUID and its oldest/newest retrieval timestamps or `null`. Bounds include every dated source in the selected documents. Missing or invalid retrieval dates are unknown, not an indication that evidence is new.\n\nEach rendered document section includes `Retrieved:` followed by one timestamp, an oldest-to-newest range, or `unknown`. These are retrieval dates, not publication or event dates. Freshness is reported, not enforced: the compiler does not refresh or reject old evidence. Source locations are not added to this line or the manifest; the existing structured `documents[].sources` payload is unchanged.\n\n#### Recheck selected assessment evidence — pending API release\n\nThis optional addition is documented against [API #1208](https://github.com/recoupable/api/pull/1208), reviewed source `1de332ebeae6b74c6f21866482175d33cd843009`. It is pending the coordinated API release. Until that release is verified, existing clients must omit `selected_evidence`. This extends `read_brief`; it adds no endpoint, generic object resolver or grant.\n\nUse the captured saved assessment's `snapshot.id` as `brief_id`. Optional `selected_evidence` contains 1–8 exact rows from that same snapshot's `brief.input_manifest.documents`. Every row requires `documentId` (UUID), `resultId` (UUID or `null`), `subjectId` (UUID), `topic` (1–128 characters), finite numeric `version`, and `sourceVersionIds` (1–32 unique UUIDs). Reject duplicate document IDs and duplicate source-version IDs; source-version sets must match exactly, with order ignored. Do not send names, quoted text, inferred kind/owner, UI revision or client request IDs in these rows. `organization_id` retains its existing authorized-scope meaning.\n\nWithout `selected_evidence`, the response remains `{snapshot}` and no evidence-validation result is added. With it, the same response also carries `evidence_validation`: either `{state: \"unavailable\"}` or `{state: \"available\", documents: [...]}`. Available rows preserve selection order and contain `documentId`, `subjectId`, the server-derived domain `kind`, `identityConfirmed: true`, and `sourceVersionIds`. Domain kinds remain distinct: `material`, `company`, and `recording` are not interchangeable. A client must not infer kind from a label or treat this result as permission to act.\n\nOnly a matching, saved, non-superseded `company_onboarding` snapshot qualifies. Every selected row must match both its saved manifest/document and current accepted evidence, including owner, result, subject, topic, numeric version and exact source set. A confirmed, unambiguous kind must come from a target in the same request that actually returned that document. Missing, changed, withdrawn, superseded, malformed or unconfirmed evidence makes the entire selection unavailable; no partial attributed rows are returned. Without the optional explanation described below, the unavailable result has no reason code. The authorized snapshot is still returned under its existing read contract, so evidence-validation unavailability does not itself mean the snapshot was deleted or withheld.\n\nThe check reads only the snapshot's server-derived requests: 1–10 unique request IDs, at most 100 targets and 1,000 documents per request. Exceeding those bounds yields unavailable rather than a truncated success. Malformed selection requests, bounds violations and duplicate IDs use the existing invalid-input error; authorization and storage failures remain errors, not successful unavailable results. Owner authorization is rechecked after all reads.\n\nThis is a bounded read-only check, with no save, refresh, dispatch or identity inference. It does not establish factual accuracy, rights, an atomic cross-request snapshot or continued availability after the read. Hosts need workspace, pending-request, snapshot-identity and generation guards before using an asynchronous result. The two selected-evidence examples below were generated through the actual HTTP/MCP operation with synthetic authentication/storage; they do not prove deployed or customer behavior.\n\n#### Explain an unavailable selection — pending API release\n\nThis opt-in addition is documented against [API #1209](https://github.com/recoupable/api/pull/1209), reviewed source `97eb158f7634a856adafdcf99a127421068d4799`. It is pending release. Until the compatible API release is verified, omit `explain_evidence_validation`. Other Context actions and their availability are unchanged.\n\nWhen a person reopens a saved company assessment and selects evidence to reuse, the existing selected-evidence check can report unavailable without explaining which check failed. Add `explain_evidence_validation: true` to the same `read_brief` request, with its captured `brief_id` and exact `selected_evidence`, to request one broad explanation. This helps the client explain why it cannot verify that selection; it does not fix or refresh the evidence.\n\n`true` requires `selected_evidence`. The server rejects true without a selection as invalid input before storage reads (HTTP 400; MCP error). This runtime rule is not encoded as a conditional in the source-exported JSON Schema. Omitted or false preserves the exact old response: no selection still returns only `{snapshot}`; a selected unavailable result remains `{state: \"unavailable\"}` with no reason; available retains exactly the same attributed rows and never gains a reason, even with true.\n\nFor an opted-in unavailable result, `evidence_validation` is `{state: \"unavailable\", reason: \"...\"}`. `reason` is one of:\n\n| Reason | What the check could not verify |\n| --- | --- |\n| `saved_assessment_unavailable` | A valid, matching, saved, non-superseded company assessment and consistent request references. |\n| `selection_mismatch` | Exactly one saved manifest row and document matching each selected six-field reference and workspace owner. |\n| `current_evidence_unavailable` | Matching current evidence and usable request/target records within the assessment's existing request scope. Missing, malformed, duplicated or changed records may produce this reason. |\n| `identity_unconfirmed` | A confirmed, unambiguous domain kind from a target in the same request that returned the selected document. Missing or conflicting target identity can produce this reason. |\n| `validation_limit_exceeded` | The existing read bounds: at most 10 requests, 100 targets per request and 1,000 documents per request. This is distinct from malformed selection input, which remains an error. |\n\nThe reason reports the first failed check in the existing validation path; it is not a complete list or a ranking of causes. It means Recoup could not verify the selection, not that evidence was necessarily withdrawn, false or unauthorized. The check adds no lookups, raw errors or identity details. Authorization failures, storage exceptions and the final owner-access recheck retain their existing error behavior; they are not converted into successful unavailable responses.\n\nKeep the existing snapshot and selection guards. Treat unavailable as unavailable rather than passing its sources to another feature as validated. The explanation grants no access or rights, changes no evidence, and guarantees neither factual accuracy nor availability at a later action. The 18 additional example pairs below come from synthetic executions of the HTTP and MCP operations: available plus each of the five reasons, with the flag omitted, false and true. They verify source behavior only, not production or any private customer case.\n\n### Link retained evidence\n\n`attach_evidence` links one exact retained `source_version_id` to 1–100 distinct existing targets: an artist, a professional, or a Context request/subject pair. Supply a stable `idempotency_key`; retry only the same version and targets with that key. Authentication supplies the actor. The receipt records relevance only; it does not confirm identity, rights or a business mandate. It creates no roster entry and makes no provider/model call or charge.\n\n`read_evidence_attachment` reads one receipt by `attachment_id`. `list_evidence_attachments` reads a page for an exact source version. Pass `next_id` as `after_id` while `has_more` is true, including an empty page where protected receipts were withheld. Reads check current workspace access, source retention and independent target access. Evidence responses and domain errors are private and must not be cached. A later source version needs a separate association; these actions do not rewrite historical receipts. They require the matching evidence-association database and API release; accepted request syntax is not hosted availability.\n\n### Scope and failures\n\nAuthentication determines the account. Optional organization_id selects an authorized organization workspace; request and subject ownership are checked again by the operation. Invalid request syntax returns 400, missing authentication 401, rejected organization access 403, and operation conflicts, unavailable evidence or disabled verification 409. No action accepts a caller-supplied account identity. Local schema tests do not establish hosted availability.\n\n### MCP mapping\n\nStandard MCP uses the `context` tool with the same action and fields as this REST request. The three evidence actions also have individually discoverable object-schema tools listed separately below; they are excluded from delegated OAuth connections. Delegated OAuth exposes the named tools below and supplies the action server-side; omit action from the named tool input. These registrations require the full `mcp:tools` grant, current ownership and fresh credential verification. Read-only is a tool annotation, not a guarantee of hosted readiness. Discover the actual tools in the connected client before use; this is a static source mapping, not a verified client catalog.\n\n| REST action | Delegated OAuth tool | Classification |\n| --- | --- | --- |\n| `list_release_cases` | `list_music_release_cases` | Read-only hint |\n| `read_release_case` | `read_music_release_case` | Read-only hint |\n| `read_release_case_review` | `read_music_release_case_review` | Read-only hint |\n| `review_release_case` | `record_music_release_case_review` | Writes or dispatches |\n| `save_brief` | `save_music_context_brief` | Writes or dispatches |\n| `read_brief` | `read_music_context_brief` | Read-only hint |\n| `plan` | `plan_music_context_research` | Read-only hint |\n| `list_executions` | `list_music_context_executions` | Read-only hint |\n| `list_catalog_members` | `list_music_context_catalog_members` | Read-only hint |\n| `list_release_tracks` | `list_music_context_release_tracks` | Read-only hint |\n| `read_release_track_observations` | `read_music_release_track_observations` | Read-only hint |\n| `review_release_track_identities` | `review_music_release_track_identities` | Read-only hint |\n| `verify_release_tracks` | `verify_music_release_tracks` | Writes or dispatches |\n| `expand_catalog_members` | `expand_music_context_catalog` | Writes or dispatches |\n| `plan_catalog_members` | `plan_music_catalog_research` | Read-only hint |\n| `read_execution` | `read_music_context_execution` | Read-only hint |\n| `ingest_catalog` | `import_catalog_context` | Writes or dispatches |\n| `ingest_artist` | `import_artist_context` | Writes or dispatches |\n| `ingest_songwriter_name` | `import_songwriter_context` | Writes or dispatches |\n| `ingest_company_name` | `import_music_company_context` | Writes or dispatches |\n| `ingest_campaign_brief` | `import_music_campaign_brief` | Writes or dispatches |\n| `ingest_supporting_text` | `import_music_supporting_text` | Writes or dispatches |\n| `ingest_release` | `import_music_release_context` | Writes or dispatches |\n| `verify_release` | `verify_music_release` | Writes or dispatches |\n| `ingest` | `import_song_context` | Writes or dispatches |\n| `read` | `read_music_context` | Read-only hint |\n| `brief` | `compile_music_context_brief` | Read-only hint |\n\n### Standard-only evidence and catalog tools\n\nThese tools are available to standard MCP clients after the required database/API release. They are excluded from delegated OAuth connections pending organization-grant review.\n\n| REST action | Standard MCP tool | Classification |\n| --- | --- | --- |\n| `attach_evidence` | `attach_music_evidence` | Writes |\n| `read_evidence_attachment` | `read_music_evidence_attachment` | Read-only hint |\n| `list_evidence_attachments` | `list_music_evidence_attachments` | Read-only hint |\n| `save_catalog_case` | `save_catalog_case` | Writes |\n| `read_catalog_case` | `read_catalog_case` | Read-only hint |\n| `list_catalog_cases` | `list_catalog_cases` | Read-only hint |\n\n### Success responses and examples\n\nThe success model depends on the requested action. The table and `x-recoup-context-responses` connect each action to its HTTP status and complete named model; use that model rather than the union of all successful results. Request and response examples use synthetic authorized storage and mocked dispatch. A 202 receipt means queued, not completed. No example authorizes a provider call, collection, spending or new access.\n\nSaved request `input`/`output` JSON and historical execution-node/outcome metadata remain intentionally flexible. A saved request or execution record is not a guarantee of complete evidence, verified identity or rights. `read` may include metadata-only `material_evidence` on HTTP/standard MCP; delegated OAuth omits that receipt.\n\n| Action | HTTP status | Response model |\n| --- | --- | --- |\n| `attach_evidence` | 200 | `ContextEvidenceAttachmentReceipt` |\n| `read_evidence_attachment` | 200 | `ContextEvidenceAttachmentReceipt` |\n| `list_evidence_attachments` | 200 | `ContextEvidenceAttachmentPage` |\n| `list_release_cases` | 200 | `ContextReleaseCasesResponse` |\n| `read_release_case` | 200 | `ContextReleaseCaseResponse` |\n| `read_release_case_review` | 200 | `ContextReleaseCaseReviewResponse` |\n| `review_release_case` | 200 | `ContextReleaseCaseReviewResponse` |\n| `save_brief` | 200 | `ContextBriefSnapshotResponse` |\n| `read_brief` | 200 | `ContextBriefSnapshotResponse` |\n| `plan` | 200 | `ContextModulePlanResponse` |\n| `list_executions` | 200 | `ContextExecutionsResponse` |\n| `list_catalog_members` | 200 | `ContextCatalogMembersResponse` |\n| `list_release_tracks` | 200 | `ContextReleaseTracksResponse` |\n| `read_release_track_observations` | 200 | `ContextReleaseTrackObservationsResponse` |\n| `review_release_track_identities` | 200 | `ContextReleaseIdentityReviewResponse` |\n| `verify_release_tracks` | 202 | `ContextReleaseTrackVerificationResponse` |\n| `expand_catalog_members` | 200 | `ContextCatalogExpansionResponse` |\n| `plan_catalog_members` | 200 | `ContextCatalogPlanningResponse` |\n| `read_execution` | 200 | `ContextExecutionResponse` |\n| `ingest_catalog` | 200 | `ContextRequestResponse` |\n| `ingest_artist` | 200 | `ContextRequestResponse` |\n| `ingest_songwriter_name` | 200 | `ContextRequestResponse` |\n| `ingest_company_name` | 200 | `ContextRequestResponse` |\n| `ingest_campaign_brief` | 200 | `ContextRequestResponse` |\n| `ingest_supporting_text` | 200 | `ContextRequestResponse` |\n| `ingest_release` | 200 | `ContextRequestResponse` |\n| `verify_release` | 202 | `ContextReleaseVerificationResponse` |\n| `ingest` | 202 | `ContextRequestResponse` |\n| `read` | 200 | `ContextReadResponse` |\n| `brief` | 200 | `ContextBriefResponse` |\n| `save_catalog_case` | 200 | `ContextCatalogCaseResponse` |\n| `read_catalog_case` | 200 | `ContextCatalogCaseResponse` |\n| `list_catalog_cases` | 200 | `ContextCatalogCasesResponse` |\n\n### Catalog case continuation\n\n`save_catalog_case`, `read_catalog_case` and `list_catalog_cases` persist bounded catalog workflow artifacts as `customer_assertion` evidence. They are source contracts requiring the corresponding catalog-case database/API release; source tests and this reference do not prove deployment. No artist, ISRC, bank connection or ingestion request is required. Existing Context workspace authorization applies. These operations cannot register music, resolve a provider dispute, send correspondence or establish payment; `external_actions` is always `unsupported`.\n\nSave uses a UUID `case_id`, `expected_revision` (0 for a new case), `idempotency_key`, and a portable version-1 snapshot. Its workspace must be the authenticated owner, its case ID must match, and its revision must equal the expected revision. A saved receipt advances the revision. Snapshots contain scope and dictionaries of sources, assessments, findings, actions, attempts and outcomes; IDs must be unique, source references versioned, dependencies retained and acyclic. Each collection is limited to 1,000 records; the artifact is limited to 1 MiB. Arbitrary JSON extensions accept finite JSON with at most 100 nested levels. Unknown fields and local `history` are rejected, not dropped. Use record `data` for typed workpapers. Action payloads require nonempty provider/operation/account/party strings, nonempty subject identifiers, a nonempty scope object and explicit disclosure/cost arrays. Expired historical authorization assertions remain readable; caller-recorded authorization never grants provider authority.\n\nReplay an uncertain save with the same idempotency key, expected revision and unchanged snapshot. Re-read before editing a conflicting revision. Read supports an optional historical revision, and rechecks current access and retained Context source versions. Linked withdrawn sources and dependent records are withheld even in historical reads. A `partial` snapshot with `snapshot_usable_for_save: false` must be explicitly reassembled from permitted evidence before another save. A stale reference to an older source version requires a retained binding from this same case's earlier saved history; an imported stale record without that binding cannot be saved as though its provenance were known.\n\nList defaults to 50 cases and accepts a 1–100 limit. Pass `next_id` as `after_id` while `has_more` is true. Storage orders by creation time and ID descending; the UUID cursor is an opaque case reference, not a sortable boundary by itself. Responses use private/no-store caching. All three operations are standard MCP only and excluded from delegated OAuth. Prepared, submitted, provider-accepted, observed-correct and bank-received remain separate assertions that need their own actual evidence; artifact storage certifies none of them.",
