Subject: [PATCH 1/3] Add explicit schema question Views and deferred evidence
 acquisition

Extract standalone question contracts, candidate review and chronology repair, maintained schema Views, typed inventory and page protocols, and sanitized Questions/acquisition controls. Keep discovery explicitly per-View and preserve unrelated memory surfaces.

 ## Architecture
 
+### Schema-defined questions
+
+The Memory hub's Questions workspace is a complete projection of versioned
+schema-view slots, including proposed and rejected slots. The inspector reviews
+candidates and exact source revisions, records schema-validated user assertions,
+and edits versioned rubrics without rewriting source evidence. Question and
+answer state, review, freshness and coverage are displayed separately.
+
+Question decisions are ranked, grouped by view and capped at five groups. Dismissal
+and one-day snooze use the existing fingerprint preferences; changed evidence
+resurfaces decisions, and Questions can restore dismissed decisions. Source
+mentions are not independent votes.
+
+Assisted authoring requires explicit approval to generate a proposal and an
+explicit maintenance scope; generated slots still require approval. Discovery is
+opt-in, bounded and explicitly invoked. Neither operation authorizes tools.
+`memoryGetViewPage` returns deterministic Markdown and a `memory-view:` URI;
+Markdown links preserve exact revisions, slots and collection item keys when
+opened in the browser. Optional service capabilities and operation errors are
+reported explicitly, not interpreted as empty inventories. Question lists use
+bounded summary pages; selecting a question separately loads its full evidence.
+There is no corpus-wide discovery policy or knowledge-status control.
+
+Questions also shows acquisition progress and explicit run-once/cancel controls
+for existing host-authorized requests. Its RPC projection excludes staged
+content, authorized arguments and raw request errors. The workspace cannot admit
+acquisition requests, enable periodic work or authorize tools; unsupported and
+disabled hosts are reported explicitly. Ingestion receipts link to ordinary
+activity and retained-source pages.
+

+## Schema-defined questions
+
+Generic View protocols include `schemaView` definitions, candidates, support
+lineage and `schema-defined-v1` build receipts. Both typed clients expose
+`listQuestions`, `editQuestion`, `getViewPage`, `proposeSchemaView` and
+`discoverSchemaQuestions`. Page results preserve deterministic `memory-view:`
+URIs and exact revisions. Proposals are drafts, not facts; slot approval and
+bounded discovery remain explicit guarded edits.
+
+`listAcquisitionProgress`, `runAcquisitionProgress` and
+`cancelAcquisitionProgress` return sanitized progress only, including the
+`ingested` (indexed but not yet resolved) state. They do not return staged
+content, host authority, outbound arguments or raw request errors. Acquisition
+admission and periodic scheduling remain host-only. Unsupported capabilities
+fail explicitly.
+
 ## Explicit agent-session imports
 
 Both clients and the RPC facade expose optional `importAgentSession`,

 ## Tool details
 
+Schema-defined Views round-trip through generic View tools. The bounded tools
+`memory_questions_list`, `memory_question_edit`, `memory_view_page`,
+`memory_schema_view_propose` and `memory_schema_questions_discover` expose the
+question inventory, guarded review, deterministic pages and explicit authoring.
+Proposals are not facts: approve slots explicitly and configure finite discovery
+before requesting discovery.
+
+`memory_acquisitions_list`, `memory_acquisitions_run` and
+`memory_acquisition_cancel` expose sanitized acquisition progress and explicit
+run/cancel controls. They omit staged content, outbound arguments, host
+authority and raw request errors. No acquisition admission or periodic-scheduler
+tool is registered. Unsupported or disabled capabilities fail explicitly.
+
+The loopback HTTP host uses a fresh connection per stateless MCP request.
+Tool-catalog validation in SDK clients can synchronously outlast the HTTP
+keep-alive window; explicit connection closure prevents the next request from
+reusing an expired pooled socket. Tool schemas and output validation remain
+enabled.
+
 Agent-session import is opt-in and separate from ordinary ingestion:
 
 - `memory_agent_session_import`: explicit session ID, import type

+### Explicit schema-defined question Views
+
+`schemaView` is a persisted, versioned View kind with restricted data-only answer
+schemas and explicit question slots. Slots support singleton, record and keyed
+collection answers; candidate values retain exact source citations and separate
+review, freshness, coverage and answer states. Versioned rubrics select by most
+recent evidence, independent support or manual review. An authenticated user can
+confirm/reject candidates, assert a typed answer, edit a contract or approve/reject
+a proposed question without rewriting retained evidence.
+
+`proposeSchemaView` creates unapproved contracts from an explicitly supplied
+specification and maintenance scope. `discoverSchemaQuestions` is an explicit,
+per-View call with opt-in cumulative bounds; enabling discovery does not run it.
+Ordinary ingestion maintains approved question answers within their configured
+source scope, but does not discover questions across the corpus. Evidence audits
+cover every source-origin candidate, including unselected candidates. One bounded
+repair can correct evidence and chronology bindings before independent revalidation.
+Timezone-free reports are comparable only within the same evidence-supported local
+chronology; ingestion time never establishes fact time.
+
+`listQuestions` returns full details; `listQuestionSummaries` provides bounded,
+filtered summary pages and `getQuestion` loads one complete question.
+`getViewPage` resolves deterministic Markdown and exact revision/slot/item
+`memory-view:` links without inference. These methods are available through typed
+in-process, browser RPC and MCP clients. Source removal and corpus clearing purge
+question evidence and history through the existing privacy lifecycle.
+
+### Deferred evidence acquisition
+
+Hosts can authorize deduplicated, consumer-tracked evidence requests for approved
+question slots. Tools remain disabled by default. Authorization binds the
+principal, policy, tool, resource and exact outbound arguments; question text or a
+model proposal cannot grant authority. Requests inspect current answers before
+fetching and deliver fetched material through ordinary source ingestion, retaining
+ingestion receipts and reconciling overlapping question consumers. Cancellation,
+stale consumers, conflicts, indexing failures and privacy suppression remain
+explicit states, not successful empty answers.
+
+The Questions page exposes sanitized progress and explicit run-once/cancel controls
+for existing requests. Browser and MCP progress omit outbound arguments, staged
+content and raw errors. They cannot admit requests, enable periodic acquisition
+or authorize tools; those operations belong to an explicitly configured host.

+Do not turn a passage's silence into a source-wide claim that no decision was made. Report the narrower supported observations, or cite the passages needed to establish the broader claim.
+Preserve stated currency symbols and other uncertainty; do not infer a currency code or a more precise value than the source establishes.
+effectiveAt must be a complete ISO timestamp with seconds AND an explicitly supported timezone (Z or +/-HH:MM), otherwise empty.
+For a timezone-free dated report in an explicitly shared source chronology, leave effectiveAt empty and use localTimestamp in YYYY-MM-DDTHH:MM or YYYY-MM-DDTHH:MM:SS form, preserving the stated precision.
+localTimeScope identifies that shared source chronology, not a timezone. Reuse a scope only when the supplied evidence establishes one common local clock or ordered journal/conversation timeline; unrelated local clocks are not comparable.
+Cite both the report and its chronology header using passageIds. If the evidence supplies no common chronology, only a date/month, or an ambiguous event time, leave localTimestamp and localTimeScope empty.
+A dated conversation can anchor a user's explicitly contemporaneous report, but does not supply a missing timezone.
+Do not infer an event date from "just got back" alone, use capture/ingestion time as fact time, invent a timezone, or infer an old report remains true today.
+opposingPassageIds records explicit contemporaneous contradiction or refutation. Repeated or derived mentions do not establish independent votes.
+Do not mark earlier or later observations in a temporal progression as opposingPassageIds. Emit each dated observation as its own candidate with its respective absolute or local chronology and empty opposingPassageIds unless explicitly refuted at that same time.
+For historical collections, a different reported occurrence is not opposing evidence about this occurrence merely because its value differs.
+Do not change the schema, question, rubric, approval or tool authority.`;
