+## Manual review editing and draft delivery
+
+Implemented in version: **0.261.325**, tracked in
+`application/single_app/config.py`.
+
+Manual-review email and invitation cards support owner-only saved edits and
+durable AI suggestions. Direct/AI revision history survives reopening the editor
+within its bounded history window, until send/cancel. The assistant proposes
+only supported fields and never approves or sends.
+
+New manual email approvals send the actual immutable-ID Outlook draft rather
+than a second saved snapshot. Saving patches that draft; external Outlook edits
+are refreshed rather than blindly overwritten. Calendar edits remain local
+until explicit approval creates the event and sends invitations.
+
+Accepted email sends hide the obsolete draft link until a read-only lookup finds
+the current sent-message link. Up to five lookups are spaced with persisted
+backoff within a five-minute window; rapid refreshes do not spend more retries.
+If the link remains unavailable, the card directs the owner to Outlook Sent
+Items without suggesting another send. Existing retained-draft actions keep their
+compatibility behavior, and automatic/delayed delivery is unchanged. See the
+[review and draft lifecycle fix](../fixes/M365_PENDING_REVIEW_DRAFT_LIFECYCLE_FIX.md)

+# Pending Email and Calendar Review
+
+## Overview
+
+Implemented in version: **0.261.325**, tracked in
+`application/single_app/config.py`.
+
+The owner of a manually prepared Microsoft 365 email or calendar invitation can
+review and revise it without repeating the agent request. Direct edits and AI
+suggestions use the same working draft. Saving never sends email or meeting
+invitations; sending remains an explicit action on the saved card.
+
+Dependencies are the existing Microsoft 365 pending-action service, delegated
+Graph authorization, the configured action AI assistant, and the React V2
+dialog/assist framework. No delivery preference or new assistant setting is
+introduced. Shared viewers and automatic/delayed actions do not get an editor.
+
+## Technical Specifications
+
+### Owner-authorized material and revisions
+
+The editor reads the complete saved material through
+`GET /api/msgraph/pending-actions/<id>/review`, rather than rebuilding it from a
+shortened card preview. The response includes `fields`, `expected_version`, a
+sanitized `pending_action`, and a bounded `history` page.
+
+`PATCH` to that endpoint accepts `expected_version`, editable `fields`, an
+`origin` of `direct` or `ai`, and an optional `assist_turn_id`. Saves are
+conditional on the reviewed revision. Concurrent edits or delivery claims
+produce a visible conflict instead of silently overwriting newer content.
+
+Calendar inputs retain the authoritative wall time and timezone. Graph's
+seven-digit fractional seconds are shortened only for native input display;
+unmodified timestamps keep their original precision when other fields are saved.
+Offset-bearing timestamps represent instants and display in the selected
+timezone, including Windows timezone names resolved by the review response's
+bounded `timezone_aliases` metadata. Offset-free Graph wall times are not
+converted. Display conversion never rewrites saved fields; unsupported browser
+zones show the unchanged ISO timestamp with an explicit notice rather than
+silently dropping its offset.
+
+For email, Save updates the actual Outlook draft. For calendar, it updates the
+local invitation material; Outlook event creation and invitation delivery occur
+only on Send. A partial email save stays non-sendable until the server reconciles
+the Outlook and stored review material.
+When the server offers **Edit** for an expired editing claim, reopening performs
+that authorized reconciliation; it does not bypass the send restriction.
+
+### AI assistance and durable history
+
+`POST /api/msgraph/pending-actions/<id>/assist` accepts the current
+`expected_version`, editable `fields`, `instruction`, and `submission_id`.
+The service reuses the configured editor-assist model, limits and typed proposal
+contract. The browser validates the field allowlist, displays the proposal in
+the working copy, and adopts the new revision created by recording the turn.
+It never invokes a delivery endpoint.
+
+`GET /api/msgraph/pending-actions/<id>/history?cursor=<cursor>&limit=20`
+loads another bounded page. History is stored separately from the pending
+delivery receipt, with direct/AI attribution and saved/applied state. Closing and
+reopening rereads saved history. Ordinary close retains the in-memory Ask AI
+input/thread for reopening, while confirmed unsaved field edits are discarded.
+Pending local exchanges are cancelled on close. Losing edit authorization
+removes that action's global assist entry even with the editor closed; terminal
+or denied actions also clear active review material. A temporary processing
+pause keeps existing field edits read-only until authorized recovery.
+History reads adopt a newer revision only when the saved fields are unchanged.
+If another edit changed those fields, the working copy stays visible but locked
+until an explicit saved-draft reload, rather than overwriting the newer material.
+Persisted suggestions retain their original working-field snapshot and proposed
+fields. After reopening, **Apply suggestion** copies only changed allowlisted
+fields still matching that snapshot. Newer edits survive with a visible warning.
+The result is an unsaved AI-attributed working change, not a save or delivery.
+
+Undo uses the shared editor-assist rules: only a field still holding the
+revision's value returns to its earlier value. Later edits survive. Undo itself
+is another unsaved working change. Sending or cancelling clears active review
+history without removing the final delivery receipt.
+
+### Card preview and links
+
+The card shows the subject/title, recipients/attendees and five rendered body
+lines immediately. **Show More** / **Show Less** appears only for overflow or a
+shortened server preview. HTML goes through the existing locally vendored
+DOMPurify boundary, preserving safe prose and links without scripts, styles,
+remote images, forms or embeds.
+While the local sanitizer is loading, the card shows a preparing-preview status.
+If it fails, the body stays hidden with an explicit error and a local-asset retry;
+raw HTML source is never used as a preview fallback.
+
+Resource links describe their actual destination: draft, verified sent message,
+legacy retained draft, or created calendar event. A pending sent-copy link does
+not point back to a stale draft or enable another send. Microsoft 365 acceptance
+does not establish recipient delivery.
+While `link_pending` is true, the existing card refresh cycle checks status
+read-only; backend backoff bounds actual Graph lookups. A resolved
+`link_status: available` enables the verified sent-message link. Exhaustion
+changes only the link to `unavailable`, with an explicit Outlook Sent Items
+notice. The action remains accepted, without exposing a stale draft URL or
+offering another send.
+
+### File structure
+
+Frontend sources under `application/v2_ui/src`:
+
+- `components/approvals/PendingActionCard.tsx` and `PendingActionBody.tsx`
+- `components/approvals/PendingActionEditor.tsx` and `usePendingActionReview.ts`
+- `lib/pendingActionReview.ts` and `stores/pendingActionReviewStore.ts`
+
+Backend review/history services:
+
+- `application/single_app/functions_m365_pending_review.py`
+- `application/single_app/functions_m365_review_history.py`
+- `application/single_app/route_backend_msgraph_pending_actions.py`
+
+## Usage Instructions
+
+1. Read the outgoing action card and expand a long body if needed.
+2. Choose **Edit** on a manual-review action you own.
+3. Change email To/Cc/Bcc, subject, body and body format. For calendar, check title,
+   attendees, start/end, timezone, location, body and the existing Teams option.
+4. Optionally use **Ask AI & history** to propose a change. On mobile, switch
+   between **Draft** and **Ask AI & history** without losing the working copy.
+5. Review changed fields and **Save changes**. Use **Undo this change** to revert
+   eligible fields, then Save again.
+6. Close the editor and explicitly choose **Send** or **Cancel** on the card.
+
+Cancel/Escape asks before discarding unsaved edits. A failed save keeps the working
+copy available. **Reload saved draft** explicitly replaces that working copy with
+the latest authorized server material after confirmation.
+Closing also refreshes the card's saved material and revision, including after
+discarding an AI suggestion. This refresh never sends or saves the suggestion;
+the next explicit Send uses the refreshed saved action.
+
+## Testing and Validation
+
+- `functional_tests/test_v2_pending_review_logic.mjs` executes real typed field
+  proposals, safe undo, owner/manual gates, history normalization, assist-revision
+  adoption and CSRF-protected request contracts.
+- `ui_tests/test_v2_pending_review_editor.py` drives real React components with
+  the actual compiled theme at desktop/mobile widths. Coverage includes direct
+  and AI saves, reopen/history paging, later-edit-safe undo, stale AI rejection,
+  recipient typing, discard, configurable AI availability and sanitized HTML.
+- `ui_tests/test_v2_m365_pending_action_cards.py` covers live/reloaded card
+  placement, keyboard expansion and explicit mocked Send/Cancel.
+- `functional_tests/test_m365_pending_review.py` covers the backend service
+  boundaries. All Graph/delivery calls in development validation are mocked.
+
+The editor does not add recurrence, attachments, retroactive draft cleanup,
+sent-message editing, a new send policy, or an extra AI approval gate. External
+Outlook edits are not made atomic by a pre-send version check.

+# Microsoft 365 pending review and draft delivery (v0.261.325)
+
+Fixed/Implemented in version: **0.261.325**
+
+Related version update: `application/single_app/config.py`.
+
+## Review cleanup (v0.261.326)
+
+Removed unused imports from the review service and placement regression test,
+and removed an unused delivery-result binding while preserving the delivery
+call. This maintenance change does not alter review or sending behavior.
+
+## Issue and root cause
+
+Manual email approval previously sent a saved message snapshot through
+`/me/sendMail`, leaving the prepared Outlook draft behind. Its link still pointed
+to that draft after sending. Pending emails and invitations also lacked an
+owner-authorized, durable editing and AI-assistance contract.
+
+This change concerns new manual-review emails and local invitation preparation.
+It does not delete old drafts, migrate historical actions, replay deliveries, or
+change delayed/automatic delivery policies.
+
+## Review APIs and authorization
+
+The existing pending-action Blueprint now exposes:
+
+| API | Behavior |
+| --- | --- |
+| `GET /api/msgraph/pending-actions/{id}/review` | Loads the owner's full saved fields and recent history; refreshes known Outlook draft changes. |
+| `PATCH /api/msgraph/pending-actions/{id}/review` | Saves validated fields using `expected_version`, with `origin` and optional `assist_turn_id` attribution. |
+| `GET /api/msgraph/pending-actions/{id}/history` | Returns bounded history, using `limit` (1–40) and `cursor` paging. |
+| `POST /api/msgraph/pending-actions/{id}/assist` | Proposes field-constrained changes to an unsaved working draft; never saves or sends the proposal. |
+
+Read responses contain `pending_action`, `fields`, `history`, and
+`expected_version`. Assistant responses additionally contain the shared editor
+assistant's `reply`, `candidate`, `changes`, and `warnings`, plus flat
+`candidate_fields` and `assist_turn_id`. Suggestions and successful edits
+advance the action version because their history is committed atomically.
+All four owner review responses also expose `timezone_aliases`, a bounded copy
+of the same fixed Windows-to-IANA mapping used by backend validation. This is
+display metadata, not a setting or editable draft field. It lets the browser
+display offset-bearing Graph instants in the selected zone while retaining the
+original stored datetime strings until an explicit edit.
+
+All routes retain login/user policy and Swagger security. Mutations require the
+existing M365 CSRF token. Owner checks and current conversation authorization
+precede full-field/history access; shared viewers do not receive them. Only
+manual, bound, editable actions can be saved or assisted. Sending, editing,
+cancelled and terminal actions cannot be edited.
+
+For verified orchestration origins, authorized owner/shared-viewer projections
+also include `producing_user_message_id`, `orchestration_run_id` and `turn_id`.
+The capture callback derives these from the exact
+owned, conversation-bound run after validating the stored step bridge. Their
+fingerprint-bound provenance anchors list discovery before the live creation
+frame arrives. Missing or unverifiable historical origins remain unlinked;
+browser hints and arbitrary latest-message matching are not used.
+New manual email and calendar records carry `review_provenance_version=1`,
+included in their material fingerprint. Projection also requires this
+creation-time marker; historical records are not relinked merely because their
+existing execution binding contains origin fields. Delayed records do not gain
+this manual-review provenance strategy.
+
+Email fields are subject, body, content type, and To/Cc/Bcc address lists.
+Invitation fields are subject, body, content type, attendees, start/end,
+timezone, location and the supported online-meeting option. Unsupported fields,
+invalid recipients, nonexistent timezone wall times and end-before-start dates
+are rejected. Offset-bearing dates are converted into the chosen timezone.
+
+## Durable changes and AI assistance
+
+`functions_m365_pending_review.py` reuses `functions_editor_assist.py` and its
+configured model/limiter adapters. Dedicated email/calendar kinds have closed
+field-path allowlists. The model cannot propose owner, identity, delivery-policy,
+approval or send operations. Normal model filtering remains in effect; no
+additional conditional-send safety-review gate is introduced.
+The assist route enforces the existing `is_action_assistant_enabled()` predicate
+(`enable_action_ai_assistant` plus Semantic Kernel availability) before resolving
+model clients. Direct editing remains available when this existing assistant
+setting is off; no new capability setting is introduced.
+
+New manual review Save and approval also reuse configured `chat_output` content
+screening/Content Safety checkpoints. They check subject/body and all recipient
+or attendee addresses; draft approval checks the current Outlook material even
+though the draft-send POST has no JSON snapshot. Existing sharing, selected
+source/capability, and audience authorization continue through the restored
+context and Graph token checks. Disabled scanners and configured allow-unchecked
+decisions keep their existing behavior; this is not an additional AI approval
+gate. A blocked decision prevents the patch/send and returns a safe policy error.
+
+The model receives at most the shared assistant's 20 bounded turns from this
+action's server-owned thread. Client conversation limits are validated, but a
+client thread cannot replace another action's durable context. A result based
+on a superseded action version is rejected.
+An exact retained submission retry is replayed before rejecting its original
+action version: a lost response can be recovered without another model call or
+history append. The owner must still have an editable action, and its stored
+instruction/field fingerprint must match. Replay returns the current version;
+unknown submissions with stale versions and changed submission material conflict.
+
+`functions_m365_review_history.py` stores a separate record in the existing
+owner-partitioned pending-action container. An atomic batch updates the action
+and history together. History retains at most 40 records and 1,600,000 serialized
+bytes; oldest entries expire from that bounded window. Full review fields are
+limited to 750,000 serialized bytes, with a 50,000-character body limit.
+Revisions retain previous/new fields for restore, direct/AI attribution, and
+saved/applied status. Suggestions retain the instruction, reply, exact unsaved
+source fields, candidate and warnings so reopened proposal undo has both sides,
+without duplicating giant model-result snapshots.
+
+History survives closing/reopening the editor. Send/cancel removes its editable
+history without deleting the final delivery receipt. Terminal reads retry
+interrupted history cleanup and never expose old edit history. Existing owner
+data management already deletes records from this container, including the
+separate history record.
+
+## Email save and send lifecycle
+
+New manual email preparation requests `Prefer: IdType="ImmutableId"` and saves
+`graph_send_strategy=draft_send_v1`. Editing claims a conditional action lease,
+patches the actual draft with its Graph ETag, and atomically saves updated review
+material, fingerprint and history. A known external Outlook edit refreshes the
+review rather than being blindly overwritten.
+
+A Graph/Cosmos partial failure never reports successful persistence. It leaves
+the action non-sendable until a read-only draft refresh reconciles it. If storage
+is unavailable even for that failure marker, the edit claim expires after ten
+minutes so reopening can reconcile it. Calendar Save writes only local review
+material; it never creates an Outlook event or sends invitations.
+
+Approval sends the current email draft via `/me/messages/{id}/send`. The
+pre-send read is not an atomic guarantee against concurrent external Outlook
+edits and does not introduce another approval pause. A detected change refreshes
+the final reviewed projection while the existing claim/version checks still
+protect application-side concurrency.
+
+The existing one-claim/no-replay rule remains: uncertain POST outcomes require
+Microsoft 365 review and cannot trigger an automatic repeat. Calendar approval
+retains the transaction ID and records the created event ID/link.
+
+## Truthful links and compatibility
+
+Graph acceptance is not proof of recipient delivery. After draft-send
+acceptance the draft link is cleared. A maximum of five incremental, read-only
+immutable-ID lookups can discover the non-draft sent-message link. Each attempt
+is claimed in storage before contacting Graph; minimum intervals of 5, 15, 30
+and 60 seconds prevent rapid or concurrent refreshes exhausting the retries.
+The lookup window ends five minutes after acceptance. Responses expose
+`link_status` (`pending`, `available`, `unavailable`), `link_next_lookup_at` and
+`link_lookup_deadline_at` so the UI can poll at the next eligible time without
+sleeping inside a request or worker. While lookups remain eligible,
+`link_pending` is true. Exhaustion or deadline expiry clears pending and
+truthfully reports the link unavailable, with guidance to check Outlook Sent
+Items; further detail refreshes do not contact Graph or send again. Lookup
+failure never reverts accepted status or enables another send.
+

+Older retained-draft actions retain their original snapshot behavior and

+## Validation
+
+`functional_tests/test_m365_pending_review.py` covers full-field reopening,
+direct/AI revisions, local calendar saving, owner/CSRF/version enforcement,
+history bounds/paging, stale AI results, invalid fields/timezones, Graph ETag
+conflicts, concurrent save/send/cancel, partial-save reconciliation, actual
+draft send, delayed sent-copy visibility, bounded link lookup and no replay.
+
+`functional_tests/test_m365_pending_action_provenance.py` executes the real
+step bridge/capture with SDK-shaped storage, covering owned-run provenance,
+authorized shared projection, fingerprint/conversation mismatches and historical
+missing identities. It runs alongside the orchestration operation runtime suite.
+
+The focused pending-action/delivery/authorization/editor-assist suites and route
+policy tests passed with mocked Graph/model calls and SDK-shaped Cosmos
+responses. No live mail or invitation was sent during validation.

+# Stable orchestrated Microsoft 365 review placement
+
+Fixed in version: **0.261.325**
+
+## Issue and root cause
+
+New email review cards could appear above the request while orchestration was
+running, then move when the final answer arrived. The planner saved a different
+user-message ID from the optimistic browser ID. The run controller consequently
+rejected a correctly scoped creation event, while list discovery found the action
+without a visible message reference.
+
+The original regression tests seeded identical browser/server IDs and missed the
+normal planning-to-execution transition.
+
+## Changes
+
+The planning event now publishes the saved user-message identity bound to the
+conversation, turn, and run. The controller checks all three scopes before
+reconciling the optimistic bubble. The pending-action store follows that identity;
+it does not guess using timestamps, subjects, or the latest message.
+
+New actions carry server-bound producing-message provenance. List discovery can
+therefore attach them before their creation event arrives. They remain beneath
+the producing request when the final reply is saved, keeping an expanded card or
+open editor mounted. Existing unlinked history keeps its separate conversation
+section; this fix does not rewrite historical records.
+
+Preparation summaries point to the action card for current delivery status
+instead of claiming a draft is still unsent. This matters when the owner sends
+or cancels while the reporting step is still running.
+
+## Files and validation
+
+The identity contract spans `functions_orchestration_events.py`,
+`route_backend_orchestration.py`, `orchestration.ts`,
+`orchestrationController.ts`, and `chatStore.ts`. Placement is handled by
+`m365PendingActions.ts` and `m365PendingActionsStore.ts`.
+The application patch version is recorded in `application/single_app/config.py`.
+
+`functional_tests/test_v2_m365_pending_actions_stream.mjs` exercises the real
+planner/run controller and stores over mocked HTTP with distinct IDs, list
+discovery before SSE, and final publication. It verifies one user bubble, one
+card, stable placement, and preserved expansion.
+`test_orchestration_conversation_context_routes.py` checks the identity against
+the actual saved run on the real Flask planning route.
+`test_orchestration_operation_runtime.py` checks historical preparation wording
+and that repeated approval does not repeat the draft-send POST.
+
+No validation sends real email or modifies a production mailbox.
