+## Scope
+
+This repository owns poll-backed meeting scheduling, candidate slots, participants, constraints, availability, reminders, decisions, and Calendar handoff.
+
+## Documentation Contract
+
+- Treat documentation as part of every behavior change. Update this module's manifest-driven `DocumentationTopic` contributions for affected user and administrator behavior.
+- Keep feature content here; `govoplan-docs` projects it without importing Scheduling internals.
+- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.
+
+## Boundaries
+
+- Poll owns reusable responses; Calendar owns events and free/busy; Notifications and Mail own delivery.
+- Keep optional integrations capability-driven and preserve signed-link privacy and abuse controls.

+## Participant selection boundary
+
+The editor uses Core's shared `PeoplePicker`. Its server-side search aggregates
+the optional `access.people_search` and `addresses.people_search` capabilities,
+and each provider applies the active principal and tenant visibility rules
+before returning a candidate. Scheduling exposes only the fields needed to
+select a person; provider provenance, address-book topology, group membership,
+and other internals are not returned by its picker endpoint.
+
+An account selection becomes an internal participant bound to that account.
+A visible address-book contact becomes an external participant with a bounded
+directory-selection reference and revision for later organizer editing. Manual
+name-and-email entry is available only while the request allows external
+participants. The picker stores neither provider-internal provenance nor a

+
+The request detail projects the existing backend lifecycle into three stable
+user stages: prepare the request, collect participation, and decide. Draft,
+collecting, closed, decided, handed-off, cancelled, and archived records remain
+the authoritative backend states; the stage rail is only a readable projection
+and does not invent a second workflow state machine. Cancelled requests keep the
+reached stage visible as stopped, while later stages remain locked.
+
+Unavailable Calendar coordination and public guest participation use Core's
+action-blocker pattern. The UI names the reason, required remediation,
+responsible administrator, and destination instead of displaying a generic
+disabled control. Stable help links resolve to the configured Docs module when
+present and to the hosted documentation otherwise. Scheduling contributes the
+`scheduling.find-and-decide-meeting-time`, `scheduling.calendar-coordination`,
+and `scheduling.participation-governance` topics; it does not import Docs,
+Calendar, Poll, Policy, or Access implementation code.
+
+The next slices should add generic self-enrolment links after their abuse and
+identity policy is agreed, Calendar hold cleanup after decision, and advanced
+scoring constraints such as required participants and quorum rules.
 
 The active backlog lives in Gitea issues.
+
+## Signed-participation policy gate
+
+Scheduling persists the response policy and snapshots it onto each governed
+Poll invitation. Public access uses
+`/scheduling/public/{request_id}/{token}`; Poll's ordinary public routes reject
+these gateway-bound tokens, so callers cannot bypass Scheduling's password and
+request checks. Passwords are write-only, stored only as salted PBKDF2 hashes,
+and failed checks are throttled through Redis when configured with a bounded
+in-process fallback.
+
+Poll is the transactional authority for response rules. Its governed submission
+holds the Poll-row lock while enforcing single choice, `Maybe`, participant
+email, comments, idempotency and per-option capacity. Scheduling then updates
+its participant projection in the same database transaction. Candidate-slot
+add/remove and participant-link revocation also go through the governed Poll
+capability; exact retries are idempotent, and option mutations invalidate only
+the affected answers.
+
+Public submissions lock the Scheduling request and participant rows before
+entering Poll, matching organizer edit lock order and making first-use email
+binding atomic. Both authenticated and public submission paths independently
+require the Scheduling request to be collecting and its deadline not to have
+passed, so a stale or incorrectly reopened Poll projection cannot accept a
+response. Changing a request deadline transactionally updates each governed
+invitation's expiry in Poll under owner- and gateway-bound row locks. The same
+link and invitation identity survive future, past, extended, and cleared
+deadlines: a past deadline makes the link unusable, a later extension makes the
+same link usable again, and clearing the deadline removes its expiry. No raw
+replacement token crosses the PATCH response, and existing responses plus
+participant status remain attached to the same durable respondent identity.
+
+Cancellation closes the backing Poll, so submission fails, while active links
+remain usable as a reduced cancellation notice for a bounded period. The
+deployment setting `SCHEDULING_CANCELLATION_NOTICE_DAYS` defaults to 30 and is
+bounded to 1–90 days. Cancellation transactionally aligns governed invitation
+expiry with that timestamp. The public projection contains only the request
+title and cancellation timestamps; descriptions, locations, candidate slots,
+comments, and previous answers are omitted. After the bound, access fails with
+the same generic response as an invalid or expired link.
+
+If the governed capability is absent, API responses advertise that policy
+enforcement is unavailable and restricted links fail closed. Plaintext
+passwords, token hashes, response-gateway internals and the participant roster
+are not exposed by the public response model.
+
+Authenticated participant list/detail projections likewise omit tenant,
+organizer, Poll and Calendar identifiers, connector metadata, invitation and
+identity bindings. Free/busy conflicts are reduced to useful time/status
+fields. Organizers and scheduling administrators retain the full management
+projection; participants retain candidate-slot revisions, their own marker and
+email, response settings, aggregates, and any roster names/statuses permitted
+by the configured privacy policy.
+
+The WebUI package registers `/scheduling/public/{request}/{token}` through
+Core's explicit, backend-allowlisted public-route contract. The guest page uses
+the shared UI components, prompts for email/password only when needed, prefills
+an existing response, and enforces the snapshotted response rules. The token
+stays in the path and is never copied into query parameters or browser storage.
+Signed-in users also receive an in-app deep link without weakening the signed
+guest-link boundary.
+
+Creating, editing, and opening a request never issue public tokens or enqueue
+invitation delivery. The deprecated `create_participant_invitations` request
+field remains accepted for compatibility, defaults to `false`, and has no side
+effect. Authenticated in-module responses can still lazily create a
+gateway-bound invitation whose token is discarded.
+
+Organizers and Scheduling administrators use the participant-specific
+invitation action instead:
+
+- `POST /scheduling/requests/{request_id}/participants/{participant_id}/invitation`
+  with `{"action":"copy","participant_revision":"..."}` rotates the previous
+  invitation and returns the new relative action URL once. The response is
+  marked `no-store`.
+- The same endpoint with `{"action":"send"}` rotates the invitation and passes
+  its URL directly to the notification dispatch job; it also requires the
+  current `participant_revision`. Neither the API response nor Scheduling's
+  durable notification projection contains the token.
+- `DELETE` on the same resource uses a JSON body containing the current
+  `participant_revision` and revokes the active link immediately. A revoke
+  against the refreshed no-link projection is an idempotent replay.
+
+The semantic participant revision includes the current invitation identity.
+It is checked after the participant row is locked, so stale copy, send, and
+revoke commands return `409` before rotating a newer link or delivering to a
+changed recipient.
+
+The participant DataGrid presents copy, send, and revoke as a fixed icon-only
+action group. Authorized but unavailable actions remain visible and explain
+why they are disabled: for example, delivery is disabled without a dispatch
+provider or recipient target, and revoke is disabled when no active link
+exists. The delivery capability is exposed only in management projections.
+Copy accepts only the same-origin Scheduling public path and does not persist
+the bearer URL in component state, logs, or browser storage.
+
+Links can be issued in any request state. Collection state and deadline checks
+remain independent submission requirements, so a link to a draft, closed, or
+decided request is read-only. Issue, copy, send-request, and revoke actions are
+audited with request and participant identifiers but never a bearer token.
+Only an organizer (under the ordinary Scheduling write policy) or a tenant-wide
+Scheduling administrator can use these actions. If notification delivery is
+not installed, `send` fails before rotating the current link and the organizer
+can use `copy` for separate distribution.
+
+Participant edits carry a semantic revision so a stale organizer form cannot
+overwrite an invitation or response change. Corrections that retain a stable
+account or directory identity update the existing participant. A display-name
+correction keeps its invitation; changing a delivery email revokes the stale
+link but keeps a response tied to the unchanged account identity.
+
+Changing the canonical identity creates a new participant instead of assigning
+the former participant's response to another person. In the same transaction,
+Scheduling revokes the old invitation and Poll soft-deletes every matching
+live response. Poll retains the answers and a bounded retirement record for
+audit, while result summaries and capacity checks immediately exclude them.
+Removing an invited or responding participant follows the same retirement
+path. Scheduling records privacy-safe audit facts and queues a removal or
+replacement notice to the former recipient without placing email addresses or
+response contents in the audit event.
+
+## FieldLabel omission register
+
+Scheduling uses the shared `FieldLabel` for form controls that need explanatory
+inline help. The only intentional omissions are:
+
+- Candidate-slot and participant DataGrid cells: column headers supply the
+  visible label and each interactive cell has an accessible name.
+- Per-slot availability selects: the enclosing visible slot/date text is the
+  native label for that individual choice.
+
+There are no other authorized Scheduling omissions. Inline help remains
+controlled by the user's shared interface setting; hiding it does not remove
+accessible labels.
+
+## Git-source WebUI package
+
+The repository root exposes `@govoplan/scheduling-webui` for Git-tagged release
+dependencies. It mirrors the owning `webui/package.json` version, public
+TypeScript/CSS exports and peer requirements, with entry paths under
+`webui/src`. Consumers provide the shared Core/React peers; the facade runs no
+development or install scripts. The source archive contains `webui/src`, this
+README and any repository license file. Run module development checks from `webui/`; Python
+installation remains governed by `pyproject.toml`.
+
+Das Repository stellt `@govoplan/scheduling-webui` am Wurzelpfad für versionierte
+Git-Abhängigkeiten bereit. Version, öffentliche TypeScript-/CSS-Exporte und
+Peer-Anforderungen entsprechen `webui/package.json`; die Einstiegspfade liegen
+unter `webui/src`. Gemeinsame Core-/React-Peers stellt die einbindende Anwendung
+bereit. Die Fassade führt keine Entwicklungs- oder Installationsskripte aus.
+Entwicklungsprüfungen bleiben in `webui/`, die Python-Installation weiterhin in
+`pyproject.toml` definiert.

+# Scheduling Interface Pattern Migration
+
+Scheduling implements the platform interface pattern language on its owned
+surfaces without importing optional module internals.
+
+## Surface Map
+
+| Surface | Pattern | Consequential actions | Help context |
+| --- | --- | --- | --- |
+| `/scheduling` request list and detail | Persistent list-detail workspace with a lifecycle rail | Open, close, remind, decide, create holds, create final event | `scheduling.list`, `scheduling.request` |
+| `/scheduling` create/edit | Bounded editor with unsaved-change guard and typed Core controls | Save or discard a request definition | `scheduling.editor` |
+| `/scheduling/public/:requestId/:token` | Privacy-bounded public participation form | Submit or replace the invited participant's response | `scheduling.public-participation` |
+| `scheduling.widget.open-requests` | Compact dashboard contribution | Navigate to the selected request | `scheduling.request` |
+
+## Interaction Contract
+
+- Closing a poll, creating reminder jobs or Calendar objects, and deciding a
+  final slot require a shared confirmation dialog. Invitation-link revocation
+  uses the same component with danger emphasis.
+- Disabled actions expose the active busy, permission, immutable-response, or
+  optional-capability reason through Core's action-tooltip and blocker
+  components.
+- Calendar selection uses the optional `calendar.picker` UI capability and
+  bounded Calendar scopes. Scheduling never imports Calendar WebUI code.
+- Participant selection uses Core's provider-backed `PeoplePicker`; public
+  participation receives only the privacy-bounded request projection.
+- Stable documentation topics are available from the list, editor, detail,
+  public participation page, and dashboard widget. Core resolves them through
+  Docs when enabled and through hosted documentation otherwise.
+
+## Verification
+
+Run:
+
+```bash
+cd webui
+npm run test:view-model
+npm run test:ui-structure
+```
+
+The structural check guards shared components, optional-module boundaries,
+confirmation gates, contextual documentation, public credential controls, and
+request-specific widget navigation. Backend tests validate manifest metadata,
+permission boundaries, lifecycle transitions, public participation, and
+Calendar capability behavior.
