+each request, the answer ends with a fixed disclosure, and the result is read
+again on every turn: a result that changed, was deleted, or is no longer
+readable by its owner is never answered from.
+
+Only the requester's own private conversations qualify, checked on every turn.
+
+The chat route passes its persistence, screening and model helpers in through
+``FollowUpServices``. The flow lives here so it can be tested without Flask or

+# Workflow results in chat
+
+Implemented in version: **0.261.214**.
+
+Application version tracking: `application\single_app\config.py`.
+
+Related issue: #1546 (part 6a), part of #1543. Builds on
+[V2 workflow alert notices](V2_WORKFLOW_ALERT_NOTICES.md) (#1567) and the V2
+run history link (#1562). The
+[Chat orchestration workflows roadmap](CHAT_ORCHESTRATION_WORKFLOWS_ROADMAP.md)
+describes all the phases; this is the first part of Phase 6.
+
+## Overview and dependencies
+
+A workflow such as a weekly digest does its work on a schedule and stores what
+it found. Until this version, the only place to read that result was the run
+history in Workflows. To ask a question about it, the user had to copy the
+output into chat or run the workflow again.
+
+With **Use Workflow Results In Chat** on, a user can ask chat about the stored
+result of one of their own finished personal workflow runs. **Ask in chat** on a
+run in the V2 run history, or **Ask about this** on a workflow alert, opens a
+new chat with that run selected. Each answer:
+
+- uses only that run's stored result. The workflow isn't re-run, and nothing
+  else is searched, browsed or called.
+- treats the run's output as untrusted data, never as instructions.
+- ends with a fixed line, written by the server, that names the run, for
+  example "_This answer uses the stored result of the Weekly digest run of Mon
+  Jun 2, 2025, 9:02 AM CDT. The workflow was not re-run._"
+- reads the result again on every turn, and answers only if it's still the
+  result the user selected.
+- stops showing in V2 once that result is no longer available to its owner.
+
+What this version adds:
+
+- **A result reader**, `functions_workflow_result_reader.py`. It authorizes one
+  finished personal run as its owner, binds the result to a digest, and returns
+  a public descriptor and, for Follow up only, bounded excerpts.
+- **A descriptor route**,
+  `GET /api/user/workflows/<workflow_id>/runs/<run_id>/result-context`, that the
+  V2 entry points read before selecting a run.
+- **Follow up**, `functions_workflow_result_followup.py`: the chat path that
+  answers a question from the selected run's stored result.
+- **Masking on read.** An answer built from a workflow result is withheld once
+  the result is unavailable, or once the chat is no longer the owner's private
+  chat, on every read that already withholds saved analyses. A few older reads
+  that only the chat's owner can reach don't mask yet; see
+  [Known limitations](#known-limitations).
+- **Withheld collaboration copies.** Converting a chat to a collaboration stores
+  its Follow up answers withheld, and doesn't carry the chat summary over.
+- **V2 entry points**: the composer chip, **Ask in chat**, **Ask about this**,
+  and `followUpWorkflowResult` for Phase 6b's delivered message, run card and
+  recurring-workflow card.
+- **The admin setting** `enable_chat_workflow_results`, off by default.
+
+Not in this version:
+
+- **The `workflow_results` orchestration capability**, which lets an
+  orchestrated plan read a run ("What did my digest find last Monday?"). It
+  builds on Phase 5's workflow planning context (0.261.212) and on this reader,
+  so it ships in a later pull request.
+- Phase 6b's post-back delivery, run card, recurring-workflow card and chat-list
+  indicator, and Phase 6c's in-plan wait.
+
+Dependencies:
+
+- Personal workflows (`allow_user_workflows`). When
+  `require_member_of_workflow_user` is on, the user also needs the
+  `WorkflowUser` app role.
+- Durable task results. A run's tasks must have stored their results through the
+  workflow result contract (`workflow-result-v1`, with a `result_ref`). Older
+  runs keep previews only, and can't be asked about.
+- The V2 interface, for the entry points and the chip. Chat orchestration
+  (`enable_chat_orchestration`) isn't needed.
+
+## Technical specifications
+
+### Architecture
+
+1. An entry point calls `openWorkflowResultInChat(workflowId, runId, ...)`,
+   which opens a new chat and reads the run's descriptor from the descriptor
+   route.
+2. The reader authorizes the whole run as its owner and computes the digest.
+   The route returns only the public descriptor.
+3. The composer shows the chip. The first question creates the chat and sends
+   `workflow_result_context: {workflow_id, run_id, result_sha256}` with every
+   other source off.
+4. Follow up checks the gate and the chat's privacy, reads the result again with
+   the selected digest and excerpts, and asks the selected model or local agent,
+   with tools off, to answer from a fenced block of run output.
+5. The answer is saved with the disclosure line, the public descriptor and the
+   accumulated result contexts.
+6. Every later read through the shared sanitizer re-checks privacy and each
+   result the answer relied on, and withholds the answer if either fails.
+
+### Gates
+
+| Surface | Needs |
+| --- | --- |
+| Descriptor route | Signed in, `allow_user_workflows`, the `WorkflowUser` rule, and `enable_chat_workflow_results`. `workflow_results_required` refuses with 403 `workflow_results_disabled`. |
+| Follow up | The same gate, checked on every turn, plus the requester's own private personal conversation. |
+| V2 entry points and chip | The bootstrap flag `features.enable_chat_workflow_results`. |
+| Masking | Nothing. It always runs, so turning the setting off never reveals a withheld answer. |
+
+`is_chat_workflow_results_enabled_for_user(settings, user_roles)` is true only
+when the setting is a real `True` and `is_user_workflows_enabled_for_user`
+passes. The V2 bootstrap reports that combined decision in its per-user
+overrides, so the raw setting never shows a button to someone the server would
+refuse. The flag only hides UI; every server path checks again.
+
+### The reader
+
+`read_workflow_result(user_id, workflow_id, run_id, *, expected_sha256=None,
+include_excerpts=False, excerpt_budget_bytes=DEFAULT_EXCERPT_BUDGET_BYTES, ...)`
+is Flask-free. Its containers, result loader, page reader and source resolver
+can be injected.
+
+1. **Point reads in the requester's partition.** The reader reads the workflow
+   and the run with `read_item`, not with the getters that turn a storage error
+   into "not found". A missing workflow or run, a run of a different workflow, a
+   group workflow, a workflow being deleted, or a record owned by someone else
+   gives 404 `workflow_result_not_found`. Because the read happens in the
+   requester's own partition, someone else's run answers exactly like a missing
+   one. A storage error gives 503 `workflow_result_storage_unavailable`.
+2. **Structured runs are closed.** A version-3 definition, a runtime
+   `schema_version` of 2, a `workflow_outputs` field, or any
+   `workflow-result-v2` task result gives 409 `workflow_result_unsupported`.
+   Their outputs need an exact node, execution and attempt selector.
+3. **Status.** `completed` and `completed_partial` are readable. `failed`,
+   `invalid`, `incomplete`, `cancelled` and `skipped` give 409
+   `workflow_result_not_finished`. Any other status, for a run that is still
+   queued or running, gives 409 `workflow_result_in_progress`.
+4. **Task rows.** One single-partition query on the run-items container reads
+   the task items, projecting only `workflow_id`, `run_id`, `task_id`,
+   `task_order`, `status`, `item_type`, `label` and `workflow_result`. A query
+   failure gives 503, never an empty result, and more than 200 rows gives 409
+   `workflow_result_invalid`. The eligible tasks are those that `succeeded` with
+   a `workflow-result-v1` `result_ref` and its SHA-256, ordered by
+   `(task_order, task_id)`. No eligible task gives 409
+   `workflow_result_preview_only`.
+5. **The digest**, described below. A caller's `expected_sha256` that doesn't
+   match gives 409 `workflow_result_changed`.
+6. **Authorization.** `authorize_workflow_run_read(workflow, run_id,
+   reader_user_id=user_id, result_items=<the same rows>, load_result=<a
+   memoizing loader>)` checks the whole run the way run history does, including
+   every stored task result and its analysis sources. Each eligible task's
+   manifest must then name the same workflow, run, task and authoritative
+   output, and pass the runner's own completion rule
+   (`_require_completed_result`), which accepts a partial result only in a
+   `completed_partial` run.
+7. **Excerpts**, only when Follow up asks for them.
+
+#### What the result is
+
+The result is every eligible task's **authoritative output**, in run order.
+Named, non-authoritative outputs aren't included yet.
+
+#### The digest
+
+`result_sha256` is the SHA-256 of this document, as canonical JSON (sorted keys,
+compact separators, ASCII), over every eligible task:
+
+```json
+{"version": "workflow-result-v1", "workflow_id": "...", "run_id": "...", "status": "completed",
+ "outputs": [["<task_id>", "<authoritative output name>", "<result_ref sha256>"]]}
+```
+
+A task's `result_ref` SHA-256 covers its stored manifest, which covers every
+output the task wrote, so rewriting any included result changes the digest. The
+digest doesn't depend on the excerpt budget, and it's computed from the same
+rows that authorization checks.
+
+No readable run can change in place today: `resume-failed` resumes only
+`failed`, `invalid` and `incomplete` runs, and the non-durable path starts a new
+run. The digest guards against any future in-place rewrite. The tests simulate
+one by changing a stored `result_ref` SHA-256.
+
+#### Excerpts and the budget
+
+A run's result can reach 500 MB, so Follow up reads a bounded excerpt:
+
+- **48 KB in total, and at most 8 outputs.** The final task's output comes
+  first. When other outputs follow, it gets up to half the budget, and the rest
+  share what remains in run order. An output that would get less than 512 bytes
+  is left out.
+- **Text** is cut at a UTF-8 character boundary. **Record outputs** are read a
+  page at a time, up to 8 pages, one record per line. An output of up to 256 KB
+  is loaded whole, so the store verifies its SHA-256. A larger one is read as a
+  single bounded page, and the start of its value is taken from that page, with
+  a text value cut mid-escape decoded leniently.
+- **Notes inside the fence.** Each cut output is followed by a note, such as
+  "[Excerpt truncated: the first 24 KB of 310 KB.]" or "[Excerpt truncated: the
+  first 40 of 1200 records.]", and outputs left out are counted.
+- **Model fit.** When the result and the chat history don't fit the selected
+  model, Follow up reads the excerpt again at 24, 12 and then 6 KB before it
+  refuses with `workflow_result_too_large`. An answer from saved analyses isn't
+  read again smaller; it's refused at once. The context budget is checked before
+  any model request is sent.
+- **Only a task label, an output kind and text reach the model.** No store
+  reference, producer id, workflow id or run id does.
+
+**Saved analyses in a result.** An Analyze task's output is a saved analysis,
+and it's read through the Analyze machinery rather than as text:
+`load_workflow_task_input(..., bounded=True)` returns a `SavedAnalysisInput`,
+and `_invoke_saved_analysis_chat_reply(..., saved_inputs=...)` explains it and
+checks the explanation against the saved records. The same analysis is read only
+once. When a run holds both saved analyses and plain outputs, the answer uses
+the saved analyses only, because those record checks would reject statements
+taken from plain text, and the disclosure says so. A report that combines
+several saved analyses can't stand in for them, so it's left out and disclosed.
+A run made only of such reports gives 409 `workflow_result_unsupported`.
+
+#### The public descriptor
+
+```json
+{"version": "workflow-result-v1", "workflow_id": "...", "run_id": "...",
+ "workflow_name": "Weekly digest", "status": "completed",
+ "completed_at": "2025-06-02T14:02:00+00:00", "result_sha256": "<64 hex characters>",
+ "available": true}
+```
+
+`workflow_name` is the workflow's current name, cleaned to one printable line of
+at most 80 characters. It's user-authored text, and V2 only ever renders it as
+text. The descriptor carries no store reference, excerpt or task detail.
+
+### The descriptor route
+
+`GET /api/user/workflows/<workflow_id>/runs/<run_id>/result-context`, in
+`route_backend_workflows.py`.
+
+- **Decorators:** `swagger_route`, `login_required`, `user_required`,
+  `enabled_required('allow_user_workflows')`, `workflow_user_required` and
+  `workflow_results_required`.
+- **Body:** runs the reader without excerpts, so the whole run is authorized,
+  and returns `{"workflow_result": <descriptor>}`. A closed reason returns
+  `{"error": <fixed wording>, "code": <code>}` with its status.
+- **Caching:** `Cache-Control: no-store, private`, because access is re-checked
+  on every read.
+
+Every V2 entry point reads the descriptor fresh rather than trusting one it was
+handed, so the chip always names the result as it is now.
+
+### Follow up
+
+**The request.** A chat request carries `workflow_result_context:
+{workflow_id, run_id, result_sha256}`, the only selector a browser sends, and,
+from V2, the browser's IANA `time_zone`.
+
+**Dispatch.** `run_workflow_result_follow_up(services, data, ...)` in
+`functions_workflow_result_followup.py` holds the flow.
+`route_backend_chats.py` adds a thin nested wrapper,
+`execute_workflow_result_chat_request`, that passes in the route's own
+persistence, screening, history and model helpers. It's dispatched ahead of
+saved analysis wherever a request can carry an `analysis_result_context`: the
+document-action executor, `POST /api/chat` and the streaming chat route. The
+streaming chat, document-action stream and Analyze stream routes run
+`workflow_result_request_precheck` first, so a disabled, conflicting, malformed
+or retried request is refused before any conversation is created or stream
+opened. Those routes also don't reserve an Analyze message id for a
+workflow-result request.
+
+**One turn:**
+
+1. **Gate and context**, in this order. A request carrying both a saved analysis
+   and a workflow result gives 400 `workflow_result_context_conflict`. A failed
+   gate gives 403 `workflow_results_disabled`, before the context is validated.
+   A malformed context gives 400 `workflow_result_invalid_context`, and a
+   request that also carries a retry or edit id gives 400
+   `workflow_result_retry_unsupported`. The retry and edit routes refuse Follow
+   up turns themselves; see [Retry and edit](#retry-and-edit).
+2. **Conversation.** The requester's conversation is loaded, or a personal one
+   is created when the request has no id, as saved analysis does.
+   `conversation_is_private` must pass on every turn. Shared, collaborative and
+   converted chats, and someone else's chat, give 403
+   `workflow_result_private_only`. A chat that no longer exists or was deleted
+   gives 404 `workflow_result_conversation_unavailable`.
+3. **Input screening.** The question goes through `check_chat_content`, and a
+   blocked question is rejected like any other chat message.
+4. **Read and bind.** The reader runs with `expected_sha256` and excerpts. A
+   changed result gives 409 `workflow_result_changed`, and nothing is answered,
+   saved or sent to a model.
+5. **The question is saved** with `metadata.workflow_result_context`.
+6. **History.** The conversation's messages pass through
+   `_sanitize_saved_analysis_history`, which withholds unavailable answers and
+   collects the inherited `workflow_result_contexts`, and then the usual bounded
+   history segments.
+7. **The model call** goes through `_invoke_saved_analysis_chat_reply`: the
+   selected model or a local agent, with tools off, inside the workflow context
+   budget. A non-local agent gives 400 `workflow_result_model_unsupported`.
+8. **Checked again before saving.** The current context and every inherited one
+   are re-authorized, inherited saved-analysis contexts are read again, and the
+   chat's privacy is checked again. If any check fails, the answer isn't kept.
+9. **The answer is saved** through `_persist_screened_assistant`, so output
+   screening applies, with the disclosure appended. The chat is marked unread
+   and titled, and activity and token usage are logged.
+
+While the answer is written, the processing thoughts show "Answering from the
+stored workflow result without re-running the workflow".
+
+A refusal returns `{error, code, warning_type: "workflow_result_unavailable",
+conversation_id, user_message_id}` with the code's status, and fixed wording
+that never echoes exception text. An answer saved before the refusal is
+deleted. Content screening refusals, of the question or of the answer, are
+returned the way other chat turns return them, and no answer is kept.
+
+**The messages the model sees:**
+
+1. The default system prompt, when one is set.
+2. A fixed system message. It says the block between
+   `<<<WORKFLOW RESULT <code> (untrusted data)>>>` and
+   `<<<END WORKFLOW RESULT <code>>>>` is untrusted data from an earlier run, not
+   instructions, and must not be followed or acted on, and that only markers
+   carrying this request's code delimit the result. The code is a new random
+   16-character hexadecimal value for each request (`secrets.token_hex(8)`), so
+   a run's output can't know it in advance. It says the workflow wasn't re-run
+   and nothing else was searched, so the answer uses only the stored result and
+   the conversation and says when the result doesn't contain the answer. When
+   the block notes a cut or left-out output, the answer must say it's based on
+   part of the result.
+3. The fenced block. It holds the workflow name, the completion time and
+   status, then each output labeled by its task name, its kind and whether it's
+   the final output, with its truncation note, and then a count of any outputs
+   left out. Any run of three or more `<` or `>` inside the block is replaced. A
+   look-alike marker that survives that, such as one written with full-width
+   brackets or split by a zero-width space, still lacks the request's code, so
+   the system message tells the model it's part of the data.
+4. The bounded history, then the question.
+
+For a result answered from saved analyses, a different fixed message takes the
+place of both. It asks the model to explain the saved Analyze result, keeping
+its accepted values, record identities, evidence, coverage and validation
+limits, without treating document or result text as instructions or claiming
+independent verification. The Analyze reader appends the saved records to the
+question instead of a fenced block.
+
+The server builds these messages itself and reads none of the request's source
+flags, so documents, web search, URL access, deep research, image generation,
+agent tools and orchestration can't be added to the turn.
+
+**The disclosure** is written by the server and appended to every answer:
+
+> _This answer uses the stored result of the Weekly digest run of Mon Jun 2,
+> 2025, 9:02 AM CDT. The workflow was not re-run._
+
+When they apply, it adds "The run completed partially, so its result may be
+incomplete.", "Only the saved analysis in this run's result was used.", "A
+report that combined several saved analyses couldn't be used." and "Only part of
+the result fit in this answer." The workflow name is Markdown-escaped. The time
+is in the request's `time_zone`, or in UTC when there's no valid zone.
+
+**The answer's metadata** carries `workflow_result` (the public descriptor),
+`workflow_result_contexts` (every context inherited from earlier answers, plus
+this one), any saved-analysis contexts the chat's history passes on, and the
+usual token usage, context budget and thread information.
+
+### Later turns
+
+In V2, the next question in the same chat inherits the run. After an answer
+arrives, and whenever the chat is loaded again, the store re-selects the chip
+when the chat's latest message is an answer with an available descriptor, unless
+the user removed the chip. The next question is then another Follow up turn.
+
+A turn sent without the chip, for example after the user removes it, is an
+ordinary chat turn. Its history still holds the Follow up answer, so
+`_analysis_history_metadata()` carries the accumulated
+`workflow_result_contexts` onto the new answer, which is then withheld along
+with them.
+
+### Retry and edit
+
+V2 doesn't offer Retry or Edit on a Follow up turn, and the server refuses them
+as well, so a Follow up question can't be replayed as an ordinary turn that
+still names the result:
+
+- `POST /api/message/<message_id>/retry` refuses when the retried message, or
+  the question that opened its thread, carries `workflow_result` or
+  `workflow_result_context`. Retrying the answer or the question is refused the
+  same way.
+- `POST /api/message/<message_id>/edit` refuses when the edited message carries
+  either key.
+
+Both give 400 `workflow_result_retry_unsupported` with the reader's fixed
+wording. The refusal comes right after the ownership checks, before content
+screening, so a refused request writes nothing: no blocked-attempt record, no
+new attempt, and no change to the active thread.
+
+A later ordinary answer that only inherited the lineage
+(`workflow_result_contexts`) isn't a Follow up turn, and retrying it is
+allowed. It replays its ordinary question through the usual history sanitize,
+so the new answer carries the contexts of every Follow up answer it can still
+see, and is masked on the same terms.
+
+### Masking on read
+
+`sanitize_saved_analysis_messages(messages, user_id, ...)` in
+`functions_saved_analysis.py` now also recognizes a message that carries
+`workflow_result`, `workflow_result_context` or `workflow_result_contexts`. Such
+a message is shown only when both of these hold:
+
+- its conversation is the reader's own private personal chat
+  (`conversation_is_private`, on a point read of the conversation).
+- every workflow result it relied on still authorizes for the reader exactly as
+  selected (`authorize_workflow_result_context`: the reader, without excerpts,
+  bound to the stored digest).
+
+A message whose stored contexts are malformed is withheld without any read.
+Otherwise:
+
+- **An answer** keeps only its id, conversation, role, timestamp, model and
+  agent names, thread and user information and masking ranges, and, for a
+  collaboration copy, its sender, message kind, reply position and source
+  message id. Its content becomes "This answer is unavailable because access to
+  the workflow result it used could not be confirmed.", its citations and
+  thoughts are emptied, and its metadata holds only
+  `workflow_result: {version, available: false}`, with no ids, name or
+  contexts.
+- **A question** keeps its text. Only the three workflow keys are removed from
+  its metadata.
+
+Both forms come from `withhold_workflow_result_message` in
+`functions_workflow_result_masking.py`. That module has no application imports,
+so collaboration storage can use it without importing the reader, and a
+withheld answer looks the same wherever it's withheld.
+
+Every exception masks, a storage failure included, and nothing is raised out of
+the read. Each distinct result is authorized once, and each distinct chat is
+read once, per call. Messages that don't use a workflow result cost nothing, and
+the existing saved-analysis logic runs unchanged on the messages that pass.
+
+Because the check is in the shared sanitizer, it covers every read site that
+already withholds saved analyses: chat history for the model, the V2
+conversation messages route (`/api/get_messages`) and search, whole-conversation
+export, collaboration, and the orchestration history readers.
+`is_saved_analysis_unavailable` also recognizes
+`workflow_result.available: false`, and `authorize_saved_analysis_message_read`
+refuses message-derived views, such as thoughts, of an answer whose result is
+unavailable. Single-message exports (Word, the email draft, and the PowerPoint
+and generated-file paths) load their message through
+`_load_export_message_for_user`, which now calls
+`authorize_saved_analysis_message_read` and so checks both lineages; before,
+it only re-read saved analyses. Conversation search skips its cache when a
+match uses a workflow result, as it does for saved analyses, so a cached
+snippet can't outlive access. A few older reads that only the chat's owner can
+reach don't run the sanitizer yet; see [Known limitations](#known-limitations).
+
+Masking re-checks access to the result, not the feature entitlement. Turning the
+setting off, or losing the `WorkflowUser` role, stops new questions but doesn't
+hide earlier answers, as with saved analyses that workflows produce.
+
+### Privacy
+
+Workflow results are personal, and they never reach a shared chat. Follow up
+refuses any conversation that isn't the requester's own private personal chat,
+on every turn, and masking applies the same rule on read. Converting a chat to a
+collaboration copies its messages, and the collaboration AI bridge feeds the
+source chat's history to shared replies, so **once a chat is shared or converted
+to a collaboration, its Follow up answers are hidden for everyone, you
+included.** The original chat's stored messages are unchanged. The
+collaboration's copies are stored with these answers withheld, and the chat's
+saved summary is cleared on both chats. Relaxing the rule later would show the
+original chat's answers again, but not the collaboration's copies or the
+cleared summary.
+
+### Collaboration copies
+
+Participants read a collaboration's copies directly, and several of those reads
+never pass through the sanitizer: the collaboration metadata route (pending
+invitees included), collaboration summaries, reply previews and MCP
+collaboration reads. So conversion withholds the answers when it writes the
+copies, in `functions_collaboration.py`:
+
+- `_copy_legacy_personal_messages_to_collaboration` replaces every message that
+  uses a workflow result with its withheld form before it builds the
+  collaboration message, so `last_message_preview` is built from the withheld
+  form as well. It doesn't ask the lineage check, because the source chat is
+  marked converted only at the end of the conversion, so the check would still
+  allow the message. An answer that only inherited the context is withheld too,
+  and a question keeps its text without the three keys. The copies are built
+  from the messages `prepare_m365_history_publication` returns, so that path is
+  withheld the same way.
+- When any copied message uses a workflow result,
+  `_carry_summary_into_collaboration` stores the collaboration's `summary` as
+  `None`, with the key present, and clears the source chat's summary. The
+  conversion's final write, which marks the source converted, saves the cleared
+  summary. The helper runs after `prepare_m365_history_publication`, so
+  clearing the summary doesn't change what the publication covers.
+  `ensure_collaboration_source_conversation` and
+  `sync_collaboration_conversation_metadata_from_source`, which runs after each
+  AI-bridge reply, then have no summary to bring back.
+- `build_collaboration_message_metadata_payload`, which merges in the source
+  message's metadata, and `mirror_source_message_to_collaboration`, which copies
+  a later source message into the collaboration, withhold a source message that
+  uses a workflow result first.
+
+The group route, `ensure_group_collaboration_for_legacy_conversation`, can also
+convert a personal chat that only group context classifies, such as a
+`group-single-user` chat. That chat is still its owner's private personal chat,
+so Follow up runs in it. For such a chat the route falls back to the personal
+store and `_copy_legacy_personal_messages_to_collaboration`, and both
+conversions decide the summary through `_carry_summary_into_collaboration`, so
+the two can't drift. A chat stored in the group container can't hold Follow up
+messages, so its messages and summary are copied as before.
+
+Orchestration history (`normalize_history_message` in
+`functions_orchestration_context.py`) skips Follow up answers and every later
+answer that inherited their context, and `validate_conversation_snapshot`
+rejects a snapshot that names one. The user's own questions stay in it.
+
+### V2
+
+| File | What it does |
+| --- | --- |
+| `lib/workflowResults.ts` | Descriptor parsing and validation, `latestWorkflowResult`, and `applyWorkflowResultContext`. That last one applies only when the selection belongs to the chat the request is for; it adds the context and `time_zone`, turns every other source off, and removes the saved-analysis, document-action, orchestration and image fields. Also the refusal wording and which refusals remove the chip, the descriptor read, the chip's sentence, and `canAskAboutWorkflowRun`. |
+| `lib/workflowResultFollowUp.ts` | `openWorkflowResultInChat(workflowId, runId, navigation)`, which every entry point uses, and `followUpWorkflowResult(descriptor, navigation)`, the seam for Phase 6b's delivered message, run card and recurring-workflow card. Only the run's identity is used, and the descriptor is read again. |
+| `lib/conversationUrl.ts` | The one-shot `result_workflow_id` and `result_run_id` parameters. They're read only with `new=1`, and `syncedConversationParams` strips them. |
+| `stores/chatStore.ts` | `workflowResultContext` beside `analysisResultContext`; selecting one clears the other. `launchWorkflowResult` starts a new chat and selects the run for the chat the first question creates. Choosing a source, uploading or switching chats clears it, and loading a chat re-selects it from the latest answer unless the user removed it. A refusal that means the run can't be asked about as selected removes the chip and shows the reason. Retry and Edit on a Follow up turn are refused with a message. |
+| `components/chat/WorkflowResultChip.tsx`, `components/chat/Composer.tsx` | The chip and its remove button, the placeholder "Ask about the workflow results…", Send disabled while the run is still opening, and orchestration off while the chip is selected. Choosing **Orchestrate** removes the chip. |
+| `components/workflows/WorkflowRunAskInChat.tsx`, in `WorkflowRunHistory.tsx` | **Ask in chat** on a run row. |
+| `lib/workflowAlertNotices.ts`, `components/notifications/WorkflowAlertCard.tsx` | **Ask about this** on a workflow alert. |
+| `pages/ChatPage.tsx` | Reads the one-shot link once, and starts the launch in a StrictMode-safe effect. |
+
+**Ask in chat** appears on a run row only in a personal workflow's history, only
+while the bootstrap flag is on, and only for a `completed` or
+`completed_partial` run that isn't a structured (version 3) run. The row checks
+the run's own definition version, because the run history doesn't know the
+workflow's. An older run of a workflow since converted to a structured one
+therefore still shows the button, and the reader refuses it with
+`workflow_result_unsupported` because the workflow's current definition is
+version 3.
+
+**Ask about this** appears on a personal workflow's alert that names a run which
+had finished (`completed` or `completed_partial`) when the alert was raised, and
+only while the bootstrap flag is on. Group alerts, alerts without a run, and
+failed or cancelled runs get no button. An alert doesn't record the workflow's
+definition version, so a structured workflow's alert still offers it, and the
+descriptor read then refuses the run with `workflow_result_unsupported`.
+Choosing it closes the alert and leaves it unread.

+
+### Logging
+
+Logs use constant messages, such as `[WorkflowResults] Workflow result
+unavailable`, `[WorkflowResults] Follow up answer refused` and
+`[WorkflowResults] A chat answer's workflow result was withheld on read.`, and
+carry only codes, stages, checks and exception type names. They never carry
+workflow names, run output, questions, answers or ids. Storage failures log at
+warning level, and closed reasons at information level.
+
+### Files
+
+| File | Purpose |
+| --- | --- |
+| `functions_workflow_result_reader.py` | The reader, the digest, the descriptor, the closed reasons and their wording, and the disclosure. |
+| `functions_workflow_result_followup.py` | Follow up: the precheck, one turn, the fenced messages and their per-request code, and the refusal payload. |
+| `functions_workflow_result_masking.py` | Recognizing a message that uses a workflow result, and its withheld form. No application imports. |
+| `route_backend_chats.py` | The nested wrapper, the dispatch and prechecks, and inherited contexts in the history helpers. |
+| `route_backend_workflows.py` | The descriptor route. |
+| `functions_saved_analysis.py` | Masking on read, `is_saved_analysis_unavailable` and `authorize_saved_analysis_message_read`. |
+| `functions_collaboration.py` | Collaboration copies, the metadata payload and mirrored messages stored withheld, and the dropped summaries. |

+
+## Usage
+
+### Enable or configure
+
+1. Turn on **Enable Personal Workflows**. If **Require WorkflowUser App Role**
+   is on, assign the `WorkflowUser` role to the people who should use this.
+2. In **Admin Settings > Workflow > Workflow**, turn on **Use Workflow Results In
+   Chat**. It's off by default, and while it's off nothing changes.
+
+See [Workflow settings](../../admin/workflow.md).
+
+### What a user does
+
+1. In **Workflows**, the user opens a personal workflow's run history and
+   chooses **Ask in chat** on a finished run, or chooses **Ask about this** on a
+   workflow alert.
+2. A new chat opens with the chip "Answering from the Weekly digest run of Mon,
+   Jun 2, 9:02 AM — not re-running the workflow".
+3. The user asks a question. The answer ends with the disclosure line.
+4. Later questions in that chat keep using the run until the user removes the
+   chip.
+
+The user guide is
+[Ask about workflow results](../../guides/ask-about-workflow-results.md), and
+the controls are listed in
+[Chat controls](../../reference/chat-controls.md#workflow-results-in-chat-v2-interface).
+
+## Testing and validation
+
+### Test coverage
+
+| Test | What it covers |
+| --- | --- |
+| `functional_tests/test_workflow_result_reader.py` | Owner-only reads and the non-disclosing 404, every status family, preview-only and structured runs, the real run authorizer, storage failures as 503 rather than "not found", the digest (deterministic, independent of the budget, changed by a rewritten result), the items projection, excerpts, budgets, truncation notes and lenient decoding, saved analyses and combined reports, and a drift check against the runtime store's terminal states. |
+| `functional_tests/test_workflow_result_followup.py` | One turn with the real reader and fake route helpers: private chats only on every turn, the digest binding, no sources whatever the request says, the fixed system message and fence, the per-request fence code (a forged, full-width or zero-width-split end marker stays inside the data, and the code differs per request), the disclosure, input and output screening, agents, the descriptor and inherited contexts on the answer, the re-check before saving, budget steps, mixed runs and the refusal payload. |
+| `functional_tests/test_workflow_result_chat_routes.py` | Dispatch at every chat entry point and the stream prechecks, then an offline boot of the real application answering through the real JSON, SSE and history routes. |
+| `functional_tests/test_workflow_result_review_paths.py` | An offline boot of the real application, through `functional_tests/test_support/workflow_result_offline_app.py`. Converting a chat to a collaboration stores its Follow up answers and inherited answers withheld and keeps each question's text without the keys; the preview, a pending invitee's metadata and history, the summary input, MCP collaboration reads, mirrored messages and the M365 publication see only the withheld form; and both summaries stay empty after the source and sync calls, even when the hidden source's summary is regenerated. The group route's conversion of a group-classified private chat does the same, and a group-classified chat without workflow results keeps its summary on both chats. The Word, PowerPoint and email exports of a single message refuse a converted chat and a lost result and still export a normal message. Retry and edit refuse Follow up turns before any content check or write and still replay ordinary turns. A search whose matches use a workflow result is never written to the cache. |
+| `functional_tests/test_workflow_result_masking.py` | Withholding on read for a deleted run, a changed result, lost source access, a storage failure, another reader and a chat that isn't private; the masked shape; the question's text kept; the read sites; and the per-call cost. |
+| `functional_tests/test_workflow_result_orchestration_lineage.py` | Orchestration history skipping workflow-result answers and later answers that inherited them, while keeping the questions. |
+| `functional_tests/test_workflow_result_privacy_import_cycle.py` | Saved analysis and Follow up import the privacy check lazily from the memory module and never from the workflow planning context, the planning context reuses that one definition, and the memory module imports none of the modules that ask it. Each module loads cold in either order, with and without `-O`, with no network access. |
+| `functional_tests/test_chat_workflow_results_admin.py`, `functional_tests/test_v2_admin_workflow_parity.py` | The default, the guard, the classic and V2 admin switches, the gate and decorator, and the bootstrap flag. |
+| `functional_tests/route_tests/test_workflow_result_context_policy.py` and the route inventory and unauthenticated contract tests | The descriptor route's decorators, gates, owner-only answers, error map and caching. |
+| `functional_tests/test_workflow_results_clients.mjs` | The V2 helpers: descriptor parsing, request shaping, refusal wording, the chat link, entry point gating and the retry and edit guard. |
+| `ui_tests/test_chat_workflow_results.py` | The real V2 chat page, composer, store, run history and alert card against a fake server: Ask in chat, the chip, an inherited second question, refusals on the descriptor read and on the stream (including a changed result), a question sent while the run is opening, Ask about this, the setting off, reopening inherited and withheld chats, Orchestrate, and a workflow name that stays text. |
+
+### Performance
+
+- **One check of a result** (the descriptor route, each Follow up read, the
+  re-check before saving, and masking) costs 2 point reads (the workflow and the
+  run), 1 single-partition query on the run items, one manifest load per
+  eligible task plus the consumed-ancestor loads of run authorization, shared
+  through one memoizing loader, and source authorization for any Analyze
+  lineage. There's no history paging, because structured runs are closed.
+- **A Follow up turn** reads the result once with excerpts, and again for each
+  budget step it needs, then re-checks the current and every inherited context
+  before saving.
+- **Every chat send** runs the history sanitize, so a conversation that holds a
+  Follow up answer pays one conversation read plus one run authorization per
+  distinct context on each turn, and that authorization includes the manifest
+  loads and the consumed-ancestor loads. Opening such a conversation pays the
+  same once per read. Conversations without Follow up answers pay nothing.
+- **A single-message export** of an answer that uses a workflow result pays
+  one run authorization per distinct context, and reuses the chat it already
+  read for the privacy check. Other messages export as before. **Converting a
+  chat** only checks each message's metadata keys, with no extra reads.
+- **Excerpts** are at most 48 KB of text per turn. A large output is read as
+  one bounded page, and a record output as at most 8 pages.
+
+### Known limitations
+
+- **Personal workflows only.** Group workflows come in a later phase.
+- **Structured (version 3) runs aren't supported.** Ask in chat is hidden for
+  them, and the server refuses them with `workflow_result_unsupported`. It also
+  refuses an older run of a workflow that has since been converted, which still
+  shows Ask in chat, and a structured workflow's run reached from Ask about
+  this.
+- **Authoritative outputs only.** Named outputs aren't read.
+- **Part of a large result.** An answer sees at most 48 KB of excerpts from up to
+  8 outputs, and says so when it saw only part of the result. A run with more
+  than 200 task rows can't be read.
+- **Mixed runs** are answered from their saved analyses only.
+- **Retry and Edit** on a Follow up question or answer are refused, by V2 and
+  by the server, with 400 `workflow_result_retry_unsupported`. Ask the question
+  again instead. A later answer that only inherited a workflow-result context
+  retries as an ordinary turn, and its history is withheld on the same terms.
+- **Output formats**, such as "make this a CSV", aren't supported in Follow up.
+- **Orchestration history omits Follow up answers and later answers that
+  inherited their workflow-result context**, until the `workflow_results`
+  capability ships.
+- **Shared and converted chats.** Once a chat is shared or converted to a
+  collaboration, its Follow up answers are hidden for everyone, you included.
+  The original chat's stored messages are unchanged. The collaboration's copies
+  are stored with these answers withheld, and the chat's saved summary is
+  cleared on both chats.
+- **No retention setting.** A run's result stays available until the run is
+  deleted.
+- **Classic chat** has no entry points or chip, and its message list is one of
+  the owner-only raw reads below.
+- **Owner-only raw reads.** A few older reads return a personal chat's stored
+  messages without the sanitizer, so they still show the chat's owner an answer
+  whose result is no longer available: classic chat's
+  `/conversation/<id>/messages`, the personal branch of
+  `/api/message/<id>/metadata`, personal chat summaries (a new one is generated
+  from the stored messages, and one already saved on the chat stays) and MCP
+  reads of personal chats. Only the chat's owner can reach them, and
+  saved-analysis answers have the same gap. Saved-analysis answers are also
+  still copied into a collaboration as stored. Both are tracked as follow-ups
+  shared with saved analysis.
+
+### Follow-ups
+
+- The `workflow_results` orchestration capability, in a later pull request built
+  on this reader and Phase 5's workflow planning context.
+- Structured (version 3) runs, with their node, execution and attempt selectors.
+  Until then, hiding Ask in chat on older runs of a converted workflow and Ask
+  about this on a structured workflow's alerts needs the workflow's definition
+  version in the run history and the alert.
+- Named, non-authoritative outputs.
+- Output formats in Follow up.
+- Retry and edit that keep the workflow result context. The server refuses them
+  today.
+- Withholding unavailable answers on the owner-only raw reads (classic chat's
+  message list, the personal message metadata route, personal summaries and MCP
+  personal reads), and withholding saved-analysis answers in collaboration
+  copies, together with saved analysis.
+- A retention setting (roadmap §9).
+- Group workflows (Phase 8).
+- Re-checking workflow result contexts when a generated file is published.
+- Phase 6b's delivery, run card, recurring-workflow card and chat-list
+  indicator, and `v2WorkflowRunPath`.

+### **(v0.261.214)**
+
+#### New Features
+
+*   **Workflow Results In Chat**
+    *   Ask chat about the stored result of one of your finished personal workflow runs without running the workflow again. The answer uses only that run's saved output, with every other source off, and ends with a server-written line that names the run, such as "_This answer uses the stored result of the Weekly digest run of Mon Jun 2, 2025, 9:02 AM CDT. The workflow was not re-run._" Later questions in the same chat keep using the run.
+    *   The run's output is given to the model as untrusted data, never as instructions. An answer sees at most 48 KB of excerpts from up to 8 task outputs, starting with the last task's, and says when it saw only part of the result. An Analyze task's saved analysis is explained the way **Ask about this analysis** explains it. Tools are off, and the question and answer are screened like other chat turns.
+    *   The selection is bound to a SHA-256 digest of the run's stored outputs and checked again on every question, so an answer never comes from a result other than the one selected. A changed result asks the user to select the run again.
+    *   Works only in the owner's private personal chats. In V2, and wherever chat history, search and export already withhold saved analyses, an answer is withheld once its result can't be confirmed for the chat's owner, for example after the run is deleted, after access to one of its sources is lost, or while storage can't be read. Once a chat is shared or converted to a collaboration, its Follow up answers are hidden for everyone, you included. The original chat's stored messages are unchanged. The collaboration's copies are stored with these answers withheld, and the chat's saved summary is cleared on both chats. Single-message Word, PowerPoint and email exports check the result too. Orchestration history skips these answers. A few older reads that only the chat's owner can reach, such as classic chat's message list, still show the owner an answer whose result is no longer available, as they do for saved analyses.
+    *   New admin setting **Use Workflow Results In Chat** (`enable_chat_workflow_results`) in **Workflow** settings, off by default. It needs **Enable Personal Workflows** and follows **Require WorkflowUser App Role**; chat orchestration isn't required. A new requester-only route, `GET /api/user/workflows/<workflow_id>/runs/<run_id>/result-context`, returns the run's public descriptor. Store references never reach the browser.
+    *   Personal workflows only. Structured workflow runs, named outputs, output formats, Retry and Edit aren't supported yet: the server refuses a retry or edit of a Follow up question or answer. There's no retention setting, so a result stays available until its run is deleted. Letting orchestration read workflow results, the `workflow_results` capability, follows in a later release.

+
+#### User Interface Enhancements
+
+*   **Ask In Chat And Ask About This In V2**
+    *   **Ask in chat** on a completed run in a personal workflow's run history, and **Ask about this** in a workflow alert, open a new V2 chat with that run selected. The composer shows "Answering from the Weekly digest run of Mon, Jun 2, 9:02 AM — not re-running the workflow" with a remove button, and turns other sources and **Orchestrate** off.
+    *   A run that can't be asked about as selected removes the notice and says why, rather than falling back to an ordinary chat answer. Choosing a source, uploading a file, turning on **Orchestrate** or switching chats also removes it.
+    *   (Ref: `workflowResults.ts`, `workflowResultFollowUp.ts`, `chatStore.ts`, `Composer.tsx`, `WorkflowResultChip.tsx`, `WorkflowRunAskInChat.tsx`, `workflowAlertNotices.ts`, `conversationUrl.ts`, [Chat controls](../reference/chat-controls.md#workflow-results-in-chat-v2-interface))

+title: "Ask about workflow results"
+description: "Ask chat about what one of your finished workflow runs found, without running the workflow again."
+section: "Guides"
+audience: user
+version: "0.261.214"
+---
+
+## What this does
+
+Every run of a workflow saves what it found. This guide shows you how to ask chat
+about the stored result of one finished run of one of your personal workflows.
+The answer uses only that run's saved output: the workflow isn't run again, and
+nothing else is searched.
+
+Implemented in version: **0.261.214**. Application version alignment is tracked in
+`application/single_app/config.py`.
+
+## Why you would use this
+
+By the time you read a scheduled workflow's result, such as a weekly digest, the
+work is already done. Asking chat about it lets you pull out what matters to
+you, for example "Which of these items need a decision this week?", without
+copying the output into chat or waiting for another run. Every answer names the
+run it came from, so you always know which result it describes.
+
+## Before you start
+
+- Use the V2 interface. Classic chat has no **Ask in chat** or **Ask about
+  this** button.
+- Your administrator must turn on **Enable Personal Workflows** and **Use
+  Workflow Results In Chat**. When **Require WorkflowUser App Role** is on, you
+  also need the `WorkflowUser` role. See
+  [Workflow settings]({{ '/admin/workflow/' | relative_url }}).
+- The workflow must be one of your personal workflows, and the run must have
+  completed, fully or partially. Group workflows aren't supported yet.
+
+## Ask about a run from its history
+
+1. In V2, open **My Workspace** and choose **Workflows**.
+2. On the workflow's row, select the arrow, **Show run history**. It lists the
+   workflow's 10 most recent runs.
+3. On a run that completed, choose **Ask in chat**. Runs that completed
+   partially offer it too. Runs that failed, were cancelled or are still running
+   don't.
+4. A new chat opens. While the run's result is checked, the composer shows
+   **Opening the workflow result…**, and you can't send until it's ready.
+5. Check the notice in the composer. It names the run you're asking about, for
+   example:
+
+   > Answering from the Weekly digest run of Mon, Jun 2, 9:02 AM — not re-running the workflow
+
+6. Ask your question, such as "What changed since last week?" or "Which items
+   need a decision?".
+
+{% include media.html src="guides/ask-about-workflow-results-notice.png"
+                      alt="A new V2 chat with the workflow result notice in the composer naming the Weekly digest run, its remove button, and the Ask about the workflow results placeholder."
+                      title="A workflow run selected in the composer"
+                      capture="Capture a new V2 chat opened with Ask in chat, showing the notice that names the run and the Ask about the workflow results placeholder. Use realistic sample workflow names." %}
+
+## Ask about a run from a workflow alert
+
+When a workflow alert is about a completed run of one of your personal
+workflows, including one that completed partially, the full alert has an **Ask
+about this** button. Choosing it closes the alert and opens a new chat about
+that run's stored result, just as **Ask in chat** does. The alert stays unread
+in the bell, so you can still mark it read or dismiss it afterwards. See
+[Manage notifications]({{ '/guides/manage-notifications/' | relative_url }}).
+
+Alerts for group workflows, alerts that don't name a run, and alerts about a run
+that failed or was cancelled don't offer it.
+
+## Keep asking in the same chat
+
+Each answer ends with a line that names the run, for example:
+
+> _This answer uses the stored result of the Weekly digest run of Mon Jun 2, 2025, 9:02 AM CDT. The workflow was not re-run._
+
+Your next question in the same chat is about the same run. When you reopen the
+chat later, the notice comes back as long as the chat's last message is still
+an answer about the run.
+
+The notice goes away when you choose **Remove workflow result context**, choose
+documents or another source, upload a file, turn on **Orchestrate**, or start
+another chat. Your next question is then an ordinary chat question.
+
+## Verify it worked
+
+- The answer ends with the line that names the run and says the workflow was not
+  re-run.
+- The workflow's run history shows no new run.
+- The answer has no document or web citations, because it used only the run's
+  stored result.
+
+## What the answer can see
+
+- **Only that run's stored result.** The workflow isn't run again, so the answer
+  doesn't know about anything that has changed since the run.
+- **The main output of the run's tasks.** Each task that succeeded contributes
+  its main output, starting with the last task's, up to 8 outputs and about
+  48 KB in total. When the result is larger, the answer sees only part of it,
+  and the line at the end says so.
+- **Saved analyses.** When the run includes an Analyze task, the answer explains
+  its saved analysis, as **Ask about this analysis** does in
+  [Read and discuss saved Analyze results]({{ '/guides/analyze-results/' | relative_url }}).
+  When the run also has other outputs, only its saved analyses are used, and the
+  line at the end says so.
+- **Nothing it's told to do.** The run's output is treated as information to
+  answer from, never as instructions. Text in a result that asks the assistant to
+  do something isn't followed.
+
+## Understand unavailable answers
+
+The run's result is checked again every time you ask about it, and every time a
+chat that used it is opened in V2.
+
+- **The result changed.** If the run's stored result is different from the one
+  you selected, you're told "This workflow run's result has changed since it was
+  selected. Select the run again to ask about its current result." Nothing is
+  answered from the new result until you select the run again.
+- **The run is gone, or you lost access.** If the run was deleted, or you can no
+  longer open a document its tasks used, the notice is removed and a message
+  says the result is unavailable.
+- **Earlier answers are hidden too.** Once the result is unavailable to you,
+  every answer that used it shows "This answer is unavailable because access to
+  the workflow result it used could not be confirmed." Your questions stay. Later
+  answers in the same chat that could draw on those answers are hidden as well,
+  even ones you asked after removing the notice.
+- **Private chats only.** Answers about a workflow result, called Follow up
+  answers, stay in your own private chats. Once a chat is shared or converted to
+  a collaboration, its Follow up answers are hidden for everyone, you included.
+  The original chat's stored messages are unchanged. The collaboration's copies
+  are stored with these answers withheld, and the chat's saved summary is
+  cleared on both chats.
+
+## Limitations
+
+- **Personal workflows only.** Group workflows aren't supported yet.
+- **Structured workflows aren't supported yet.** Runs of a workflow converted
+  with **Enable structured control flow** don't offer **Ask in chat**. Runs from
+  before the conversion still show it, but asking about them says this kind of
+  workflow isn't supported yet.
+- **No Retry or Edit.** Retrying or editing a question about a workflow result,
+  or its answer, isn't supported, and the server refuses it. Ask the question
+  again instead.
+- **No files.** An answer is text only. It can't turn the result into a file,
+  such as a CSV.
+- **Orchestrate doesn't read workflow results yet.** Turning on **Orchestrate**
+  removes the notice, and when Orchestrate reads the chat's history it skips
+  Follow up answers and later answers that could draw on them.
+- **No retention setting.** A run's result stays available until the run is
+  deleted.
+- **Turning the feature off doesn't hide earlier answers.** If your
+  administrator turns off **Use Workflow Results In Chat**, or you lose the
+  `WorkflowUser` role, you can't ask new questions about a workflow result, but
+  earlier answers stay visible while their result is still available to you.
+- **Classic chat** has no buttons for this, and it doesn't hide an answer whose
+  result is no longer available: when you open the chat in classic, you still
+  see it. A few other reads that only you can reach work the same way, such as a
+  chat summary you generate for the chat. Open the chat in V2 to see which
+  answers are still available.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+| --- | --- | --- |
+| A run has no **Ask in chat** | The run didn't complete, the workflow belongs to a group or is a structured workflow, or the feature is off | Choose a completed run of a personal workflow. If no run offers it, ask your administrator about **Use Workflow Results In Chat**. |
+| "Asking about the results of this kind of workflow isn't supported yet." | The workflow is a structured workflow. You chose **Ask about this** on its alert, or **Ask in chat** on a run from before it was converted. | Read the run's result in its run history. From an alert, open the alert again from the bell and choose **Open workflow**. |
+| "This workflow run has no stored result to ask about. Older runs keep previews only." | The run finished before its tasks stored full results | Run the workflow again, then ask about the new run. |
+| "Workflow results can only be used in your own private chats." | The chat is shared or was converted to a collaboration | Start a new chat with **Ask in chat**. |
+| "The workflow result and this chat's history don't fit the selected model." | The result and the conversation are too long for the model's context window | Select a model with a larger context window, or start a new chat. |
+| "The selected model or agent couldn't answer from this workflow result with its tools turned off." | The selected agent can't answer without its tools | Select a model or a local chat agent, then ask again. |
+| "The workflow result couldn't be read right now. Try again in a moment." | A temporary storage problem | Send the question again. The notice stays selected. |

+## Workflow results in chat (V2 interface)

+about the stored result of a finished run of one of your personal workflows. The
+answer uses only that run's saved output, the workflow isn't run again, and the

+"""
+Functional test for the admin switch that lets chat answer from stored workflow results.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures that ``enable_chat_workflow_results`` (Use Workflow Results In Chat) is off
+unless an administrator turns it on, that both admin surfaces save it faithfully, and that the
+gate the routes and the V2 bootstrap use follows the personal-workflow gate:
+
+* ``get_settings`` seeds it off, and the Classic settings page fills a missing value as off.
+* The V2 schema declares an off-by-default switch in the Workflow section, shown only while
+  personal workflows are on.
+* The V2 settings update coerces the submitted value and changes nothing else.
+* The Classic pane renders the switch, and the Classic form reads it like its neighbours.
+* ``update_settings`` stores only a real ``True`` as on and leaves an absent value alone.
+* ``is_chat_workflow_results_enabled_for_user`` is the personal-workflow gate plus the setting,
+  ``workflow_results_required`` refuses with a closed code, and the V2 bootstrap reports the
+  gate's decision rather than the raw setting.
+* The admin documentation names the switch by its V2 label.

+"""
+Functional test for the chat routes' workflow-result Follow up wiring.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures that every chat entry point sends a request carrying a
+workflow_result_context to the Follow up executor before saved analysis and
+before any source, conversation or stream work, and that the streaming routes
+refuse a disabled, conflicting or retried request before a conversation exists.
+A fresh offline process then boots the real application and checks, through the
+real JSON, SSE and history routes, that questions are answered only from the
+selected run's stored result with the disclosure, that a later question keeps
+the run's lineage, and that a changed result, a chat that isn't private,
+another user or a disabled setting gets its closed reason with nothing saved and
+no model call. Only storage, the model and the network are faked.

+Functional test for chat Follow up on a stored workflow result.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures that Follow up answers only from the selected run's stored
+result, reads and binds it again on every turn, refuses shared, collaborative
+and converted chats, fences the run output as untrusted data, ends every answer
+with the fixed disclosure, carries the public descriptor and the accumulated
+contexts on the answer, and never keeps an answer whose result, lineage or
+conversation changed. The reader, the result contract, the Analyze reader and
+the privacy rule are real; the chat route's persistence, screening and model
+helpers are recording fakes.

+Functional test for withholding chat answers built from workflow results.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures that an answer relying on a workflow result is withheld on every
+new read once that result is unavailable to its owner (a deleted run, a changed
+result, lost source access or a storage failure) or once the chat isn't the reader's
+own private chat; that the question keeps its text; that a failed check never raises;
+and that one read costs one authorization per distinct result and one conversation
+read per distinct chat, with nothing read for messages that don't use a result.

+"""
+Functional test for keeping workflow-result answers out of orchestration history.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures that an answer built from a stored workflow result, and any later
+answer that inherited its workflow-result context, never enter an orchestration
+conversation snapshot, while the user's own follow-up question stays. It also ensures
+a snapshot built beside such answers still validates, and a saved snapshot that names
+a message which later gained workflow-result lineage is rejected. The real history
+normalizer, snapshot builder and snapshot validator run; nothing else is needed.

+Functional test for where saved analysis and Follow up find the chat privacy check.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures that saved analysis and Follow up ask whether a chat is private through the
+orchestration memory module, which defines the check beside the audience rule it relies on,
+instead of through the workflow planning context, whose imports reach back to saved analysis and
+closed an import cycle. Both imports stay lazy, the planning context reuses the one definition,
+the memory module imports none of the modules that ask it, and each module still loads cold in
+either order, with and without -O, without any network access.

+"""
+Functional test for the workflow-result paths outside the chat history read.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+This test ensures, in a fresh offline process that boots the real application,
+that a workflow result's answer never leaves the owner's private chat through a
+copy, an export, a replay or the search cache. Converting the chat to a
+collaboration stores its Follow up answers (and later answers that inherited
+their context) withheld, keeps each question's text without its link to the run
+and drops the chat summary on both chats, so the copies, the conversation
+preview, a pending invitee's message metadata and history, the summary input,
+MCP reads, mirrored messages and the summary sync only ever see the withheld
+form. The group route converts a private chat that only group context
+classifies by the same rule, and a group chat without workflow results keeps its
+summary. The Word, PowerPoint and email exports of a single message refuse an answer
+whose run is gone or whose chat was converted. Retrying or editing a Follow up
+turn is refused before any content check or write, while an ordinary turn still
+replays. A search whose matches use a workflow result is never written to the
+search cache. Only storage, the model and the network are faked.

+Browser regressions for asking chat about a finished workflow run's stored result.
+Version: 0.261.214
+Implemented in: 0.261.214
+
+Exercises the real V2 chat page, composer, chat store, run history and workflow alert card,
+bundled by fixtures/workflow_results, against a fake server. The fake answers with the real
+reader's and Follow up's fixed wording, codes, statuses and disclosure line
+(functions_workflow_result_reader, functions_workflow_result_followup), and replaces every
+error text with a private diagnostic the page must never show. Covered: Ask in chat on
+personal runs only, the composer chip, a follow-up turn that inherits the run, refusals on
+the descriptor read and on the stream (including a result changed by resume-failed), a
+question sent while Ask in chat is still opening, the alert card's Ask about this, the
+setting turned off, reopening a chat whose latest answer used a result or was masked, and a
+user-authored workflow name that must stay text. No live application data is read or
+modified; the existing Azure Playwright connection fixture also supports a local browser.
