 ## Reference Journeys
 
-The roadmap should be driven by three journeys.
+The active sequence is selected. Workflow remains deliberately deferred and is
+not a dependency of these journeys.
 
-### Journey 1: Permit To Payment
+### Journey 1: Campaign Demonstration Composition
 
-This is the primary public-administration journey.
+Campaign is the first complete proof of modular composition. Campaign owns
+intent, recipient snapshots, personalization, execution state, and delivery
+evidence. Mail owns reusable profiles, credentials, protocol policy, and
+provider execution; Campaign stores only a selected profile reference. Files
+owns storage, connector profiles, file policy, and provenance.
 
-1. A person applies for a permit through the public portal.
-2. The applicant uploads required files and submits structured form data.
-3. Submission creates a case, a workflow instance, and an internal task.
-4. Completing the task creates a postbox message, a notification, and an email
-   notification with an appointment proposal.
-5. The applicant accepts an appointment, which updates the calendar and the
-   workflow state.
-6. During the appointment, the case is opened and the permit is generated from
-   a governed template.
-7. The payment is processed and linked to the case and accounting handoff.
-8. The permit, payment evidence, communication history, audit trail, retention
-   state, and records evidence remain available according to policy.
+The technical gate is a pinned Campaign/Mail/Files composition with central
+UI, adaptive user/admin/operator/integration documentation, target SMTP/IMAP
+and file-provider evidence, and explicit test/send/resend/retry/reconciliation
+semantics. Readers must not receive backend paths, worker claims, secrets, or
+raw provider diagnostics.
 
-This journey proves the platform can coordinate modules without core knowing
-module internals.
+### Journey 2: Function-Bound Postbox Delivery
 
-### Journey 2: Training To Certificate
+Postbox accepts delivery to an addressable postbox or a function in an
+organizational unit. Organizations owns units and functions, Identity owns
+subjects, IDM owns identity-to-function assignments and upstream sync, and
+Access resolves current roles, delegation, acting context, and permission.
 
-This is the best university-administration and internal-administration journey.
+Campaign consumes a typed delivery-target capability without importing Postbox
+or identity internals. Reassignment changes future access without moving the
+message; vacancy or ambiguous acting context fails visibly; delivery, access,
+and correction remain auditable.
 
-1. Course or training offer is planned.
-2. Room, trainer, resource, and capacity are booked.
-3. Participants register or are assigned.
-4. Attendance is tracked.
-5. Certificate or participation confirmation is issued.
-6. Evidence remains available through records, files, audit, and docs.
+### Journey 3: Data-Backed Templates, Reports, And Deep Launch
 
-This journey keeps `booking`, `resources`, `learning`, and `certificates`
-focused instead of becoming broad ERP replacements.
+An authenticated user follows an opaque, short-lived launch reference from HIS
+or another specialist system. GovOPlaN re-authorizes the actor, resolves a
+curated data context server-side, displays source/freshness/version, and renders
+one reproducible document and report.
 
-### Journey 3: Report To Resolution
+Templates owns definition/version/schema/rendering, Reporting owns source
+selection/parameters/execution/export, Files owns generated bytes, and
+connectors own protocol access. URLs do not carry credentials, arbitrary SQL,
+or trusted raw personal data. Retries are idempotent and generation evidence
+connects source, snapshot/reference, transformation, definition, parameters,
+output checksum, actor, and policy.
 
-This is the internal operations and municipal issue-reporting journey.
+### Journey 4: Governed University BI Path
 
-1. A person reports an issue.
-2. The issue is triaged into helpdesk, facilities, assets, or a case.
-3. Work is assigned, tracked, and escalated.
-4. Evidence, communication, and status updates are preserved.
-5. Reports show workload, SLA, recurring problems, and completion.
+Starting from the Journey 3 source contract, one bounded university dataset is
+catalogued, staged by snapshot or watermark, validated, transformed through a
+versioned lineage graph, and exposed as a policy-aware analytical data product.
+The result must preserve official-key mappings, organizational and reporting
+date semantics, quality findings, quarantine/replay, transparent calculation,
+and reproducible promotion between development, test, and production.
 
-This journey prevents `helpdesk`, `issue-reporting`, `facilities`, and `assets`
-from becoming disconnected ticket silos.
+Reporting consumes the product. Create `govoplan-datasources` or
+`govoplan-dataflow` only after the concrete path proves repeated ownership that
+does not belong to connectors, Reporting, or the producing domain module.
 
-## Roadmap Waves
+### Journey 5: Collaborative Document Lifecycle
+
+An uploaded or generated artifact becomes a DMS document. Files continues to
+own bytes; DMS owns identity, versions, renditions, editing sessions, locks,
+comments, review, approval, comparison, and recovery; a collaboration connector
+owns provider-specific protocol behavior; Records owns later classification,
+hold, archive, and disposal.
+
+The gate requires no silent lost updates, short-lived and currently authorized
+editing sessions, idempotent authenticated callbacks, visible uncertain saves,
+immutable accepted renditions, and a Records-ready handoff with stable content
+and provenance.
+
+## Capability Dependency Waves
+
+The waves below remain a dependency and ownership catalogue for the wider
+product vision. They are not the active delivery order. The five selected
+journeys above and the meta roadmap decide what is implemented now; other
+clusters remain dormant until a selected journey consumes them or they are
+explicitly reprioritized.

+# Shared fixed-window throttling

+Core exposes `govoplan_core.core.throttling` for security-sensitive endpoints
+that need bounded fixed-window counters. Subjects are SHA-256 hashed before they
+become store keys. A configured Redis instance provides atomic counters shared
+across API workers; development, a missing Redis configuration, and temporary
+Redis outages use a bounded process-local fallback. When Redis fails, local
+attempts are still mirrored so losing the distributed store does not reset the
+active worker's protection window.
+
+Callers define one or more `ThrottleDimension` values with a controlled
+namespace, a subject and a positive limit. They must call `check` before an
+expensive verifier, `record` after a failed attempt, and may `reset` the relevant
+dimension after successful verification. A blocked decision includes a
+`retry_after_seconds` value suitable for an HTTP `Retry-After` header.
+
+The first consumer is Scheduling's anonymous participation password challenge.
+Its namespace is `poll-participation-password`; its subject combines tenant,
+scheduling request and Poll's non-secret invitation-token fingerprint. Access's
+login throttle predates this primitive and should be migrated onto it in a
+separate compatibility-preserving slice.

 ## Confirmed Implementation Decisions
 
@@ -156,6 +167,104 @@ shared CSS tokens and persisted user preference selection.
 - Visual preview in settings is illustrative; it must reflect token families,
   not become a second theme implementation.
 
+### DUE-009: Central Component And Exception Contract
+
+Decision: module interfaces are compositions of the components exported by
+`@govoplan/core-webui`. When Core already owns the matching interaction, using
+the central component is required rather than preferred.
+
+A route or domain-specific page composed from central components is ordinary
+module composition. A new reusable UI control, presentation primitive, or
+module-local substitute is a custom component. Before one is implemented, the
+product owner must explicitly authorize it and the owning decision or issue must
+record:
+
+- its single, narrowly defined purpose and intended consumers
+- why central components or their composition cannot meet that purpose
+- the permitted scope and the boundary it must not grow beyond
+- accessibility, reachable states, theme behavior, and test expectations
+- whether the component remains domain-owned or is a candidate for Core
+
+Custom components must not duplicate, fork, or cosmetically replace a central
+component. An existing local implementation does not grant an exception. If a
+central contract later covers the need, migrate to it unless the product owner
+explicitly retains the exception.
+
+### DUE-010: Scheduling Request Reference Composition
+
+Decision: Scheduling requests provide a concrete reference application of the
+universal placement and component rules.
+
+- The persistent left panel stacks `My scheduling requests` and `Scheduling
+  requests for me`; it is list context, not a second creation affordance.
+- The left panel's `Scheduling requests` header owns one `Add` action. It opens
+  the shared view/create/edit surface in the right main panel.
+- Basic information, Calendar integration, candidate slots, and participants
+  use the central `Card` component as four logical sections.
+- Candidate slots and participants use the central `DataGrid`, including its
+  standard row-action placement and order.
+- Calendar integration uses the central `ToggleSwitch`, with its dependent
+  controls shown when enabled.
+- Each participant is edited as one structured row with name, email address,
+  and actions. The normal editor does not parse a free-form list of addresses;
+  that interaction requires a separate, explicitly designed bulk-import flow.
+
+Equivalent list/create/edit surfaces use the same underlying rules. These are
+not Scheduling-local component variants.
+
+### DUE-011: Field Help, Discard, And Table Action Contracts
+
+Decision: the central components own these interactions; modules compose them
+instead of reproducing their behavior.
+
+- `FormField` and `ToggleSwitch` already render `FieldLabel`. Direct field
+  compositions use `FieldLabel` explicitly when the meaning or limitation is
+  not self-explanatory.
+- `help` content is contextual guidance, not the accessible name. The persisted
+  `show_inline_help_hints` user preference hides only the `InlineHelp` marker by
+  applying `ui-hide-help-hints` at the document root.
+- A dirty editor registers once with `useUnsavedDraftGuard`. An explicit
+  Discard button calls `useUnsavedChanges().requestDiscard(afterResolve)`; SPA
+  navigation uses `useGuardedNavigate` or `requestNavigation`. Both paths show
+  the same shared unsaved-changes dialog. A browser tab/window unload remains a
+  browser-controlled confirmation because browsers do not permit a custom
+  modal at that boundary.
+- `TableActionGroup` receives the table's stable action set. Use `disabled` and
+  `disabledReason` for row state; omit an action only when that action does not
+  belong to the table. `minimumSlots` reserves trailing positions for an empty
+  row. `DataGridEmptyAction` does this for the standard add/move/remove layout.
+- A paginated `DataGrid` has exactly one query owner. Client mode receives the
+  complete logical row set and applies filtering and sorting before slicing a
+  page. Server mode receives only the loaded page, requires `onQueryChange`,
+  and the backend applies every emitted filter/sort before pagination while
+  returning `totalRows` for the filtered result. Server list filters declare
+  their complete option domain instead of deriving it from the loaded page.
+  External filter affordances such as summary-count shortcuts update the
+  grid's `query` contract; the grid header controls and backend query therefore
+  always display and execute the same filter state.
+- Feedback and confirmation use `Dialog`, `ConfirmDialog`, or
+  `DismissibleAlert`. They never fall back to `window.alert`.
+
+#### FieldLabel Omission Register
+
+Every Core field surface that intentionally does not render `FieldLabel` is
+listed here. Module repositories keep an equivalent register in their durable
+UI documentation until a central cross-repository audit is available.
+
+| Core scope | Why `FieldLabel` is omitted | Accessible/context label source |
+| --- | --- | --- |
+| `PasswordField`, `ColorPickerField`, `DateField`, `TimeField`, and `DateTimeField` input internals | These are label-neutral composite primitives and are placed inside `FormField`/`FieldLabel` by the consuming form. Rendering another label inside the primitive would duplicate it. | Enclosing label; a direct consumer must pass an accessible name and record that direct composition here. |
+| `ToggleSwitch` native checkbox | The shared component already renders its visible text through `FieldLabel`; the native input must not render a second label. | The enclosing native label and derived `aria-label`. |
+| `FileDropZone` hidden file input | The input is an implementation detail of the labelled keyboard-operable drop target. | Drop target text and `inputLabel`/`aria-label`. |
+| `AdminSelectionList` and `DataGrid` list-filter checkboxes | Each option is self-explanatory and already enclosed by its visible option label. | Enclosing native option label. |
+| `EmailAddressInput` compact Name and Email fields | These two conventional fields are self-explanatory in the compact address popover; richer address guidance belongs to the enclosing field. | Visible native labels; the free-form editor also has a descriptive `aria-label`. |
+| `DataGrid` page-size, filter, and inline cell editors | The surrounding column header/filter heading supplies field context; repeating a labelled help marker in every cell would add noise. | Column header, filter heading/native label, or generated cell `aria-label`. |
+| Retention-policy value controls | `PolicyRow` owns the field label, help, effective value, and provenance for its control. | The containing `PolicyRow` label/help contract. |
+
+#### Alert Exception Register
+
+No `window.alert` or global `alert` exception is authorized.
