 The runner loads the same `GovoplanServerConfig` as `govoplan_core.server.app:app`, builds the platform registry, and passes core plus enabled module source roots to uvicorn as reload directories.

 The default development database is PostgreSQL at `postgresql+psycopg://govoplan_dev@127.0.0.1:5432/govoplan_dev`. Store the password in `~/.pgpass`. To force the disposable SQLite fallback, run with `GOVOPLAN_DEV_DATABASE_BACKEND=sqlite`; that database lives below `runtime/`.

+# Automation Contracts
+
+Core defines provider-neutral automation contracts. It does not own domain
+schedules, Workflow graphs, or Dataflow execution.
+
+## Invocation Envelope
+
+`AutomationInvocation` classifies a start as `manual`, `api`, `schedule`,
+`event`, `workflow`, `dependency`, `retry`, or `backfill`. It carries opaque
+trigger and delivery references, event identity, correlation and causation
+IDs, scheduled time, requesting actor, and bounded metadata. Domain runs store
+this envelope with their immutable definition revision.
+
+## Current Authorization
+
+An automated trigger must not persist a user session, bearer token, API key,
+or a snapshot of all current permissions. It stores:
+
+- tenant, account, and membership IDs;
+- an opaque authorization reference;
+- the minimum scopes required by the pinned definition and output target.
+
+At delivery time the optional
+`auth.automationPrincipalProvider` capability resolves current account,
+membership, role, group, function, and delegation state. It intersects current
+authorization with the stored grant. Missing, inactive, or reduced
+authorization blocks the delivery before effects occur.
+
+## Definition Governance
+
+The optional `policy.definitionGovernance` capability evaluates `view`,
+`edit`, `run`, `reuse`, `derive`, and `automate` for system, tenant, group, and
+user definitions. A decision contains an ordered source path and effective
+limits. Derived definitions pin their source revision and hash and retain
+ancestor ceilings. Templates are reusable definitions and cannot run on their
+own.
+
+Without Policy, domain modules use a conservative tenant-local fallback:
+local definitions remain viewable/editable and active complete flows may run;
+inheritance, reuse, derivation, and automation are unavailable.
+
+## Delivery Durability
+
+Domain trigger implementations persist idempotent deliveries before running.
+`emit_platform_event` binds event delivery to the producer's SQLAlchemy
+transaction. When an enabled module provides `platform.eventOutbox`, the event
+is stored in that transaction and a dispatcher may retry it across restarts and
+workers. The Audit module provides the current SQL outbox implementation; the
+Celery `govoplan.events.dispatch_outbox` task drains it through the Dataflow
+event-ingestion capability and the local event bus.
+
+The outbox capability remains optional so reduced module combinations can
+start. Without it, Core queues events on the SQLAlchemy transaction and
+publishes them to the process-local bus only after the outer commit. A rollback,
+including a nested savepoint rollback, discards the corresponding events. This
+fallback is suitable for local or non-critical reactions, but it is not a
+durable multi-worker automation source. Deployments that rely on event-triggered
+work must enable the outbox provider and run the `events` worker queue and
+periodic dispatcher.

+
+| Path | Purpose | Retention | Removal |

+| Legacy tenant aliases in API response schemas | Preserves active-tenant response fields used by `0.1.x` clients. | Tagged `0.1.x` API window. | Remove at `0.2` with response-schema migration notes. |
+| Optional fields in Poll response references | Accepts providers built against the earlier Poll contract. | Tagged `0.1.x` runtime contract window. | Remove or require a new interface version at `0.2`. |
+| Legacy single-tenant summary providers | Allows modules without the batch provider introduced in `0.1.x`. | Tagged `0.1.x` module contract window. | Remove at `0.2` after manifests advertise the batch provider contract. |
+| WebUI `react-router-dom` build alias | Resolves tagged `0.1.x` module source imports to Core's single `react-router` runtime so one composition never loads two router contexts. | Tagged `0.1.x` WebUI source window. | Remove at `0.2` after every supported module tag imports `react-router` directly. |

+# GovOPlaN Compatibility Policy
+
+This document defines the compatibility window that release tooling, module
+owners, migration authors, import/export providers, and API maintainers must
+preserve. It is the source of truth for deciding whether compatibility code can
+be removed.
+
+## Database Upgrades
+
+- A released installation from every tagged `0.1.x` version is a supported
+  database upgrade origin.
+- The recorded public release-baseline ledger starts at `v0.1.7`; earlier
+  `0.1.x` tags predate production installations. If an earlier tagged database
+  is encountered, the release must provide or document a compatibility bridge
+  instead of silently treating the database as a fresh installation.
+- Released migration revision IDs and recorded release heads are immutable.
+- Each release must prove an upgrade from every still-supported recorded
+  baseline, as well as a fresh installation, before its tag is published.
+- Migration-only reconciliation needed by an old database remains available for
+  at least one subsequent major release cycle after the corresponding runtime
+  compatibility path is removed.
+
+The release-baseline format and commands are documented in
+`RELEASE_DEPENDENCIES.md`.
+
+## Configuration And Export Schemas
+
+- Writers emit only the current schema version.
+- Readers accept the current schema version and the previous two schema
+  versions.
+- Older input is rejected with a diagnostic that identifies its version and the
+  required staged upgrade or conversion path.
+- A module-owned configuration provider must version its input and output
+  schema explicitly. It must not infer an old schema from missing fields once a
+  versioned schema has shipped.
+- Round-trip and upgrade tests must cover all three readable versions before a
+  schema change is released.
+
+This window applies to configuration packages, module-owned exports, and other
+portable GovOPlaN configuration artifacts. Domain interchange standards with
+their own compatibility rules remain governed by the owning module.
+
+## Runtime And API Aliases
+
+- Compatibility aliases must emit an explicit deprecation diagnostic and point
+  to the supported replacement.
+- New callers must use the canonical contract. In-tree callers may not add new
+  uses of a deprecated alias.
+- Runtime imports, request fields, response fields, routes, and scope aliases
+  carried for the `0.1.x` split line are retired at `0.2`, with migration notes.
+- An alias may be removed earlier only when it never shipped in a tag or when a
+  security fix requires removal. The release notes must state the exception.
+- Database reconciliation code is not a runtime/API alias and follows the
+  longer database window above.
+
+## Removal Checklist
+
+Compatibility code can be removed only when all of the following are true:
+
+1. The path is inventoried as a database bridge, portable-schema reader, or
+   runtime/API alias.
+2. Its minimum retention window has elapsed.
+3. In-tree callers and published module manifests use the replacement.
+4. Upgrade, import, or API regression tests cover the retained window.
+5. Diagnostics and migration notes identify any staged action operators must
+   take.
+
+If one condition is not met, version-gate the compatibility path and record its
+planned removal release instead of deleting it.

+| `reference` | Prove a bounded journey, degraded states, recovery, and target-environment acceptance. |

+| `sector` | Specialize terminology, forms, rules, process baselines, controls, reports, and integrations for an institutional sector without forking modules. |
+| `deployment` | Declare a supported infrastructure topology, operational assumptions, health gates, and recovery evidence. |
+| `integration` | Declare external systems, provider bindings, source-authority modes, maturity, required health, and reconciliation behavior. |

+Package class is metadata and validation context, not additional authority. A
+sector package does not become a module and cannot write another module's
+tables. Packages may extend other packages only through versioned fragments and

+The contract enforces class-specific evidence. Reference packages require
+target, recovery, security, operations, accessibility, privacy, and
+documentation evidence. Deployment and integration packages require their
+corresponding target/recovery/operations evidence, while integration packages
+also name provider authority and minimum-maturity expectations. Preflight
+blocks a missing, incompatible, or unhealthy provider. A derived package may
+tighten parent module, capability, and provider requirements but cannot remove
+or loosen them. Every non-documentation claim made by reference, deployment, or
+integration packages carries a `sha256:<digest>` binding. Repository checks
+recompute those hashes, while signed package verification protects the declared
+manifest during transport.

+# Contextual Help Contract
+
+GovOPlaN exposes context-sensitive help through `F1` and the titlebar help
+control. The shell resolves a stable help identity from the focused control,
+its containing surface, and the current route. The Docs module then projects
+the best visible user or administrator topic for that identity.
+
+## Resolution Order
+
+The WebUI resolves help in this order:
+
+1. an explicit `helpContextId` or `data-help-context-id` on the focused item
+2. the focused shared control's `interfaceId`, `helpTopicId`, and label key
+3. a containing dialog, card, administration section, or page surface
+4. the current registered route, including dynamic module routes
+5. a stable route-derived fallback when no explicit identity is available
+
+Focused field and action contexts retain the page context as
+`fallback_context`. This lets Docs show a field-specific topic when one exists
+and otherwise open the owning page or module documentation instead of a generic
+help page.
+
+## Documentation Lookup
+
+Static `DocumentationTopic` contributions announce exact contexts through
+`metadata.help_contexts`. Core publishes that catalogue with the enabled module
+manifest, allowing the shell to link directly to an exact topic when possible.
+Docs still performs the authoritative audience, permission, configured-state,
+and documentation-type filtering.
+
+Core also maps explicit route, navigation, settings, and View surface IDs to
+the module's static user or administrator documentation baseline. This makes a
+page association complete by default and gives every derived field/action
+context a useful fallback. Exact `metadata.help_contexts` remain the preferred
+authoring mechanism for consequential or unfamiliar controls.
+
+When there is no exact topic, Docs resolves the page fallback and then the first
+visible topic owned by the module. If Docs is unavailable, the shell opens the
+hosted documentation with the same context parameters.
+
+## Authoring Controls
+
+Core shared controls expose stable help metadata. Prefer these props rather
+than adding custom `F1` listeners:
+
+- `interfaceId` identifies a durable UI surface or action.
+- `helpContextId` identifies a documentation context when it differs from the
+  interface identity.
+- `helpModuleId` identifies the documentation-owning module when a shared
+  control is embedded in another module's page.
+- `helpTopicId` links directly to a module-owned documentation topic.
+- translated label keys provide deterministic field identities for ordinary
+  `FormField`, `ToggleSwitch`, search, date/time, email, button, dialog, and card
+  controls.
+- `TableActionGroup` action definitions carry the same identities so focused
+  row actions can resolve consequence-specific help.
+- `PageLayout` owns the page help scope and documentation identity for ordinary
+  headed pages. `WorkspaceLayout` owns the full-canvas workspace scope and its
+  labelled primary/content panes; pages inside it use `PageLayout` in
+  `workspace` mode and retain their own route-level help identity.
+
+Module routes, public routes, settings sections, and administration sections
+may also declare `helpContextId` and `helpTopicId`. Each module must keep a
+static user/admin documentation baseline and should list its important route,
+workflow, setting, permission, and limitation identities in
+`metadata.help_contexts`.
+
+## Boundary
+
+Help identities describe presentation context; they are not authorization
+claims. Opening help never bypasses route or documentation permissions. Docs
+owns documentation projection, feature modules own their content, and Core owns
+focus capture, context resolution, and fallback routing.

+# DataGrid Sizing Contract
+
+`DataGrid` turns every declared track into a deterministic pixel layout after
+its container has a measurable width. The same contract is used on initial
+layout, container resize, persisted-layout restore, and pointer resize.
+
+## Column Declarations
+
+- `width: number` or `Npx` is the preferred pixel width.
+- `width: N%` is a preferred share of the measured container.
+- `width: Nfr` shares residual width by fraction weight.
+- `width: minmax(Npx, preferred)` combines a hard lower bound with any
+  supported preferred width.
+- An omitted width and the legacy `fill` flag are one-fraction flexible tracks.
+- `minWidth` is a hard floor. Header sort, filter, and resize controls may raise
+  the effective accessible floor.
+- `maxWidth` bounds direct user growth and free/constrained compensation. In a
+  cover layout it is a preferred maximum: passive tracks may exceed it when
+  that is necessary to keep the table flush with its container.
+
+## Layout Modes
+
+| `initialFit` | `resizeBehavior` | Initial layout | Pointer resize |
+| --- | --- | --- | --- |
+| `container` | `cover` | Real columns fill the container. Hard-minimum excess scrolls horizontally. | Growth may create horizontal overflow. Shrink first consumes overflow, then grows resizable columns to the right; it stops before underflow. |
+| `content` | `cover` | After measurement, the same cover invariant applies. | Same as cover above. |
+| `container` | `constrained` | Real columns fill the container. | Peer compensation respects every hard min/max and stops the active resize when capacity is exhausted. |
+| `content` | `free` | Declared content widths are retained. | Only the active column changes, so underflow or horizontal overflow is allowed. |
+| `container` | `free` | The initial layout fills the container. | Later user resizing is free. A right-sticky column promotes this mode to cover so its edge remains stable. |
+
+Sticky columns do not absorb ordinary cover residuals and are not resize
+compensation targets. A last resizable column may grow into overflow. It may
+shrink only by the current overflow, because shrinking farther would require a
+blank filler track. Dragging farther past that stop does not bank width changes:
+the column remains stopped until the pointer crosses the same boundary again.
+
+## Persistence
+
+Only the pixel layout resulting from an explicit user resize is persisted,
+together with the container width at which the user selected it.
+Persisted widths are keyed by a signature containing column IDs, declared
+widths and bounds, resize affordances, sticky placement, initial fit, and resize
+behavior. A changed signature discards the old override and recomputes the
+declared layout.
+
+Container reconciliation is suspended while a pointer drag is active. On
+release, the already-rendered pixel layout becomes the persisted preference.
+Reconciliation at that same container width never shrinks intentional user
+overflow, so there is no drag-end snap. If the surrounding layout later
+contracts, persisted tracks may shrink toward their hard minima. The layout
+retains only the amount of horizontal overflow deliberately created by the
+user; an exact-cover layout therefore remains exact-cover at narrower widths.
+Legacy snapshots from the former hard-pixel persistence contract are discarded
+once and recomputed from the declared column layout.
+
+## Regression Matrix
+
+`webui/tests/data-grid-sizing.test.ts` covers:
+
+- pixel, percentage, fraction, `minmax`, omitted, and legacy-fill tracks;
+- preferred max exhaustion without a synthetic filler column;
+- hard-minimum horizontal overflow;
+- fixed-only cover grids;
+- persisted overrides under growth and viewport pressure;
+- responsive contraction of persisted layouts without losing deliberate overflow;
+- stale layout signatures;
+- first and middle-column right-side compensation;
+- last-resizable-column overflow, underflow stop, and reverse-pointer boundary;
+- free, cover, and constrained resizing;
+- cover-expanded tracks that already exceed preferred maxima; and
+- preservation of the pointer layout across the commit fit.
+
+`webui/tests/data-grid-actions.test.tsx` also verifies the rendered fixed-cover
+shape and guards against reintroducing a synthetic buffer cell.

+# Data-Subject Request Contract
+
+This document defines the provider-neutral workflow for access and erasure
+requests. It is an operational control and evidence mechanism. It does not
+replace legal review, identity verification, retention policy, or the
+institution's statutory response process.
+
+## Ownership
+
+Core owns the request aggregate, lifecycle API, optimistic concurrency,
+provider discovery, export manifest, execution orchestration, and audit event
+names. Modules that store subject-related data own their search, explanation,
+retention, and mutation behavior through a `privacy.dsar.<module>` capability.
+Core never scans module tables or guesses how a foreign resource may be
+erased.
+
+Access owns the first provider. It finds tenant memberships plus safe account,
+identity, assignment, API-key, and session metadata. It does not export secret
+hashes, session tokens, IP addresses, or browser fingerprints. Tenant-local
+membership data can be anonymized and authentication material can be revoked.
+Global accounts and identities require manual system-level review because they
+may serve more than one tenant.
+
+## Lifecycle
+
+1. A privacy officer records a verified selector, purpose, legal basis, due
+   date, and internal reference.
+2. Search invokes every available tenant capability independently. A provider
+   failure is isolated and recorded; it cannot turn an incomplete search into
+   a successful one.
+3. The JSON export contains the request, records, provider runs, coverage,
+   retention reasons, execution evidence, and a SHA-256 manifest digest.
+4. An erasure request produces stable provider-owned actions. Immutable
+   evidence generates an explicit non-executable `retain` decision.
+5. Execution accepts only selected executable actions from the current plan.
+   It requires `If-Match`, the current resource revision, the dedicated erase
+   permission, and the exact `ERASE <request-id>` confirmation phrase.
+6. Provider execution is idempotent. Completed or unchanged effects remain
+   durable in the request's execution evidence.
+
+The API is rooted at
+`/api/v1/admin/privacy/data-subject-requests`. Access exposes the independent
+permissions `access:privacy:read`, `access:privacy:manage`,
+`access:privacy:export`, and `access:privacy:erase`; the built-in privacy
+officer role contains all four.
+
+## Provider Rules
+
+A provider must:
+
+- enforce tenant ownership for every record and action;
+- return stable, unique resource and action identities;
+- avoid credentials, hashes, tokens, unnecessary telemetry, and unrelated
+  third-party data;
+- distinguish mutable personal data from immutable institutional evidence;
+- state a retention reason for immutable evidence;
+- propose manual review instead of an automatic action when authority is
+  ambiguous or a resource spans tenants;
+- return exactly one execution result per requested action;
+- make execution idempotent and avoid committing the caller's transaction;
+- keep all actual mutations inside the owning module.
+
+Each active module without a DSAR provider is listed in coverage. This is a
+deliberate fail-visible state, not proof that the module stores personal data.
+An institution may call an export complete only after it has reviewed both the
+provider runs and that coverage list.
+
+## Retention And Evidence
+
+Erasure and retention are separate decisions. Stable object IDs, authorization
+history, function incumbency, formal decisions, delivery evidence, and audit
+records may remain necessary for accountability. Providers expose those items
+with a concrete reason and Core prevents them from being selected as executable
+actions. Policy may further restrict an action, but it must never silently
+loosen a provider's retention decision.
+
+All lifecycle mutations and exports produce tenant audit events. The request
+stores an evidence digest after every revision. This digest detects accidental
+or unauthorized mutation of the aggregate; it is not a digital signature or a
+substitute for signed recovery evidence.
+
+## Current Limits
+
+- Access is the first native provider. Other enabled modules appear in the
+  coverage list until they add a provider or an explicit no-subject-data
+  declaration is standardized.
+- Verification of the requester's identity and statutory deadline escalation
+  remain institutional workflows outside this API.
+- Global account or identity erasure is deliberately manual.
+- Exports are JSON. A human-readable signed response package remains a later
+  Reporting/Templates integration.

+# Durable Recovery Operations
+
+Modules must use `begin_durable_recovery_operation` for work whose effects can
+outlive the caller's SQLAlchemy transaction. The helper commits the canonical
+request hash, recovery plan, precondition evidence, running state, and lease
+fence before the caller mutates object storage, a queue, a filesystem, or an
+external provider.
+
+Each later checkpoint is written through an independent database session. A
+business-transaction rollback therefore cannot erase evidence of an earlier
+effect. Successful completion requires concrete verification checks and a valid
+hash chain. Compensation likewise records recovery-required, recovering, and
+verified-recovered checkpoints rather than reporting an ordinary failure.
+A definitive pre-effect or provider rejection records terminal `rejected`
+evidence instead of being mislabeled as success, atomic rollback, or recovery
+work.
+
+If a runtime disappears, another runtime may claim the operation only after the
+lease expires. The takeover records both fences. A stale compensatable operation
+becomes recovery-required; a stale forward-only or irreversible external effect
+becomes outcome-unknown; a database-only atomic operation is recorded failed
+because its transaction rolled back. Takeover never re-executes the original
+request automatically.
+
+Evidence and metadata may contain opaque references, digests, counts, and
+provider result codes. They must never contain credentials or resolved secrets.
+Ops is the platform surface for unresolved operation status; owning modules must
+provide the reconciliation action and business-level explanation.
+
+Database-only operations must use the durable handle's atomic terminal methods
+when their module rows and final recovery checkpoint belong to one invariant.
+Those methods stage the terminal checkpoint and lease release in the caller's
+SQLAlchemy transaction, then commit the domain rows and recovery evidence
+together. A failed commit rolls both back and leaves the previously durable
+`running` record available for stale-fence handling; modules must not commit
+their domain state first and close an `atomic` recovery record afterwards.
+
+An owning module may reconcile an `outcome_unknown` provider effect through the
+claimed durable handle's `resolve_unknown` method. External evidence that the
+effect occurred records verified success. Evidence that it did not occur moves
+the operation through recovery-required and recovering to verified recovered,
+so any later attempt must use a new deliberate idempotency key. The method does
+not infer provider state and requires the same terminal verification structure
+and hash-chain checks as ordinary completion.

+# External References And Integration Maturity
+
+GovOPlaN integrations use a shared external-reference contract instead of
+storing connector-specific URLs and identifiers in every module.
+
+An external reference identifies an object by:
+
+- external system instance
+- object type
+- stable external object ID
+- optional connector configuration
+- canonical HTTP(S) URL without embedded credentials
+- optional source version, ETag, observation time, and non-secret metadata
+
+The identity key is `system:object_type:object_id`. A GovOPlaN object may retain
+multiple references, but one reference must never silently change its identity.
+Moving or escalating work creates a new object and an explicit relationship; it
+does not rewrite either object's history.
+
+## Integration Maturity
+
+Maturity is cumulative:
+
+1. `discover`: identify configured external systems and their health.
+2. `link`: retain and open stable external references.
+3. `search`: include authorized external objects in GovOPlaN search.
+4. `read`: display authoritative external content.
+5. `publish`: create or update external content from GovOPlaN.
+6. `synchronize`: reconcile changes in both directions with conflict handling.
+7. `migrate`: perform a governed, verifiable transfer into GovOPlaN.
+8. `replace`: provide the native operational capability without the external tool.
+
+Connectors must declare and document the maturity they actually implement.
+`synchronize` requires durable cursors, idempotency, provenance, conflict
+handling, deletion semantics, and observable failures. A link-only connector
+must not imply that GovOPlaN holds an authoritative copy.
+
+## Source Authority Is A Separate Dimension
+
+Integration maturity states what an adapter is capable of doing. It does not
+decide which system owns truth for a configured object or field group. A
+binding separately selects one of the source-authority modes defined by the
+[institutional governance target architecture](../../govoplan/docs/architecture/INSTITUTIONAL_GOVERNANCE_TARGET_ARCHITECTURE.md):
+
+- `native_authoritative`
+- `external_authoritative`
+- `external_mirror`
+- `governed_sync`
+- `governance_overlay`
+- `linked_reference`
+
+A connector can therefore support `synchronize` while a tenant deliberately
+uses it only as an external mirror. Conversely, a native GovOPlaN object may
+retain link-only references to several external systems. Authority may be
+narrowed by tenant, organization, service, object type, object, field group, or
+process step and must be visible in provenance and configuration preflight.
+
+## Domain Ownership
+
+- Domain modules own native GovOPlaN objects and their authorization.
+- Connectors own protocols, credentials, discovery, transport, and sync state.
+- Search owns indexing and result aggregation, but source modules remain
+  responsible for authorization.
+- Core owns only the stable DTOs and extension contracts.
+
+The Python contract is
+`govoplan_core.core.external_references.ExternalObjectReference`.

+# Information Governance Adoption
+
+## Platform Rule
+
+Temporal browsing, purpose-aware access, retention, and institutional context
+are platform-wide information-governance dimensions. Every module receives the
+same contract by default. A module may claim `partial` or `enforced` only with
+repository-owned object scope, evidence, and limitations; it may claim
+`not_applicable` only when the dimension genuinely does not apply.
+
+Historical business data is always authorized under the current security
+state. No module may use a historical permission, membership, role, function
+assignment, or policy projection to weaken present-day access.
+
+Platform-wide adoption is tracked in
+[GovOPlaN #40](https://git.add-ideas.de/GovOPlaN/govoplan/issues/40), with
+temporal reads detailed in
+[GovOPlaN #39](https://git.add-ideas.de/GovOPlaN/govoplan/issues/39).
+
+## Manifest Declaration
+
+`ModuleManifest.information_governance` publishes four dimensions:
+
+- `temporal_browsing`;
+- `purpose_aware_access`;
+- `retention`;
+- `institutional_context`.
+
+Each dimension declares:
+
+- adoption: `not_applicable`, `contract_only`, `partial`, or `enforced`;
+- object types covered;
+- repository-local test/documentation evidence;
+- the remaining limitation for `contract_only` or `partial`.
+
+The default is intentionally `contract_only`. It applies the platform rule
+without pretending that existing domain queries and effects already enforce
+it. `reference_ready`, `supported`, and `lts` modules cannot retain an
+applicable dimension below `enforced`.
+
+## Read Contract
+
+For every persistent domain object, the owner classifies the read:
+
+1. **Current-only:** historical semantics do not exist and the API says so.
+2. **Valid-time:** select facts effective now or at the requested instant.
+3. **Bitemporal:** additionally select only revisions known by `recorded_at`.
+4. **All-validity:** return effective revisions in a bounded history view.
+
+The Core temporal middleware supplies the request context. Owners apply it in
+repositories or query helpers, include it in cache keys, return evaluated
+context, and test current/at/all plus recorded-time boundaries. Search,
+reporting, exports, selectors, counts, and drill-through must use the same
+projection as the owning list/detail API.
+
+## Purpose-Aware Access Contract
+
+Permission establishes a technical action ceiling. Purpose-aware access asks
+whether this actor, represented capacity, case/work item, legal basis, and
+declared use may access this object now.
+
+- A client-supplied purpose is an assertion, never authority by itself.
+- The owner or Policy capability validates the purpose and returns explainable
+  provenance.
+- Sensitive access can require case assignment, mandate, reason capture,
+  approval, or break-glass evidence.
+- Search, selectors, reporting, exports, background jobs, and connectors apply
+  the same decision.
+- Audit records the validated purpose identifier and decision reference, not
+  unnecessary content.
+
+## Retention Contract
+
+Every persistent object declares an owner, retention class or policy reference,
+trigger, start instant, hold behavior, review/disposition action, and evidence.
+Retention is not a generic timestamp deletion job.
+
+- Domain owners enumerate and execute their own effects through a typed
+  retention provider.
+- Policy resolves inherited ceilings and simulation.
+- Records owns record disposition; Files owns byte/object effects; Audit owns
+  audit-detail behavior; external providers declare their own effect and
+  recovery semantics.
+- Dry-run, legal hold, exact revision, idempotency, outcome unknown,
+  reconciliation, correction, and destruction evidence are mandatory for
+  consequential removal.
+
+## Institutional Context Contract
+
+Consequential objects and effects carry the relevant tenant, institution,
+organization unit, function, mandate/jurisdiction, service/case/work item,
+party/representation, decision, and record references. Context is minimized to
+what the operation needs. Organizational membership is not itself permission
+or mandate.
+
+Events, automation intents, audit evidence, records, and external effects retain
+the same governed context envelope or an exact reference to it. Consumers must
+not reconstruct authority later from mutable current structures.
+
+## Adoption Order
+
+1. Inventory every domain list/detail/search/export/effect and classify all
+   four dimensions.
+2. Migrate institutional owners first: Access, IDM, Organizations, Mandates,
+   Services, Parties, Cases, Approvals, Committee, Decisions, Voting, and
+   Records.
+3. Migrate communication and content: Addresses, Distribution Lists, Campaign,
+   Postbox, Mail, Calendar, Files, Templates, and Forms Runtime.
+4. Migrate data projections: Connectors, Datasources, Dataflow, Reporting,
+   Search, Risk Compliance, and Dashboard.
+5. Migrate workflow/task/background/provider operations and prove that no
+   asynchronous path drops context.
+6. Advance manifest claims only after owner tests and browser/reference-journey
+   evidence pass.
+
+The generated platform inventory reports adoption counts and module details.
+Gitea tracks individual migrations; the declaration is evidence and a maturity
+gate, not a substitute for implementation.
+
+## Definition Of Enforced
+
+A dimension is `enforced` only when:
+
+- all declared object types and public reads/effects use it;
+- list/detail/count/search/export/worker behavior is consistent;
+- cache and pagination semantics cannot cross contexts;
+- absence, invalid values, and inaccessible referenced context fail safely;
+- tests cover current, historical, unauthorized, replay, and module-absence
+  combinations appropriate to the dimension;
+- user/admin documentation explains behavior and limitations;
+- the manifest cites those tests and docs.

+# Institutional Context And Governed References
+
+GovOPlaN consequential work must retain enough context to answer who acted,
+for whom, through which function, under which mandate and jurisdiction, using
+which rule and evidence versions, and with which requested and observed effect.
+The shared contract lives in `govoplan_core.core.institutional`.
+
+Core owns reference shapes and provider protocols only. It does not own shared
+Mandate, Service, Party, Decision, evidence, or geography tables. Domain modules
+own persistence and authorization; optional capabilities resolve the references.
+Interactive reads use the separate platform temporal-data context documented in
+`TEMPORAL_DATA_CONTEXT.md`; it never changes current authorization or supplies
+mutation dates.
+
+## Envelope
+
+`GovernedContextEnvelope` version 1 carries:
+
+- a tenant and `TemporalRevision` with validity, recording, supersession, and
+  change reason;
+- the real account or service account and represented account, function,
+  procedure party, assignment, delegation/power, and mandate;
+- institution, organization unit, function, task, mandate, jurisdiction,
+  service, case, party, work item, workflow, approval, decision, and record
+  references;
+- versioned legal bases and evidence references;
+- information classification, purposes, retention/holds, minimization, and
+  disclosure state;
+- external-source authority, maturity, freshness, health, and conflict state;
+- language, accessibility, channel, explanation, and availability references.
+
+Every institutional reference includes the owner module, tenant, stable object
+identity, optional version/effective instant, and a protected display label.
+Cross-tenant references are rejected. Safe serialization omits labels,
+inspection URLs, formal reasoning, operative results, and conditions unless a
+caller explicitly requests the protected projection.
+
+## Semantic Providers
+
+The first provider-neutral capabilities are:
+
+- `mandates.resolver`: resolve competence for a task/authority type at an
+  effective instant and return the governing Mandate definition and evidence;
+- `services.definitions`: obtain versioned institutional service definitions;
+- `parties.resolver`: obtain effective procedure-local parties and powers of
+  representation without copying Identity or Organizations subjects; and
+- `decisions.registry`: record and retrieve formal Decisions under optimistic
+  revision control.
+
+The Mandate, Service, Party/representation, and Decision DTOs have strict
+mapping round-trips so they can cross capability, event, package, and storage
+boundaries without shared ORM models. Their lifecycle states are explicit:
+Mandates distinguish draft/active/suspended/replaced/retired, Services retain
+publication state, Parties retain effective representation and revocation, and
+Decisions retain correction, revocation, and supersession references.
+
+The DTOs are a repository threshold, not a mandate to create four modules.
+Independent persistence, lifecycle, security/operations behavior, release
+reason, reuse, and tests are still required before extraction.
+
+Mandate resolution is deterministic: Core filters candidates by tenant,
+effective interval, active state, task and authority type, stable
+organization/function identity, jurisdiction coverage, and subject type. A
+result is competent only when exactly one matching Mandate remains and it has
+no unresolved conflicts. Evidence from matching definitions is deduplicated
+and retained in the explanation result. `revise_mandate_definition` applies
+optimistic concurrency and the allowed activation, suspension, replacement,
+and retirement transitions while leaving the previous revision immutable.
+
+`revise_formal_decision` provides the equivalent lifecycle primitive for
+formal outcomes. Every accepted transition requires a new recorded revision
+and change reason, links `supersedes_ref` to the prior version, updates the
+authority envelope to the new version, and records explicit correction or
+revocation provenance. Terminal and backward transitions fail closed. Each
+Decision also records whether responsibility was human, human-reviewed
+automation, or an automated service account acting under mandate. Automation
+preparation/recommendation references remain inspectable without being
+mistaken for the responsible outcome.
+
+Procedure-party corrections use `revise_procedure_party`: the stable party
+identity is retained, a new revision and reason are required, stale writes are
+rejected, and revoked/expired/superseded assignments are terminal.
+`revoke_party_representation` separately records when a limited power ceased
+to authorize actions. This allows consuming procedures to evaluate historical
+delivery or representation authority without rewriting Identity,
+Organizations, or Addresses records.
+
+Service templates and package/tenant specializations use
+`derive_service_restriction`. The derived definition retains an explicit
+parent-version reference, cannot extend the parent's validity, audience,
+channels, or publication ceiling, and cannot remove inherited prerequisites,
+required evidence, legal bases, or bindings. This is the fail-closed semantic
+rule; configuration-package signature and provenance checks remain the package
+transport rule.
+
+`ServiceAvailabilityRequirement` represents module, capability, mandate,
+policy, connector, maintenance, audience, and configuration prerequisites with
+an explicit unavailable-or-hidden failure mode and explanation reference. The
+optional `services.availability` evaluator returns policy-scoped boolean
+assessments, reason codes, and evidence. Unknown consequential requirements
+fail closed; a reference itself never grants access.
+
+## Service Launch
+
+`ServiceLaunchRequest` and `ServiceLaunchResult` define the owner-neutral
+boundary between Portal entry and a case, form, or workflow runtime effect.
+The request carries the exact published Service definition, exact selected
+binding, tenant, acting identity, timezone-aware request time, bounded
+parameters, and idempotency key. The result must retain that exact Service and
+binding, a same-tenant target reference, optional same-tenant evidence, and
+only a relative or credential-free HTTP(S) destination.
+
+`service_launch_capability(kind)` maps bindings to owner capabilities:
+
+- `case` -> `cases.service_launcher`
+- `form` -> `forms_runtime.service_launcher`
+- `workflow` -> `workflow_engine.service_launcher`
+
+`FormDefinition`, `FormFieldDefinition`, and `forms.definitions` provide the
+owner-neutral exact-schema boundary used by Forms Runtime. Definitions carry an
+exact tenant/revision, field types/options/constraints/defaults, publication,
+draft, attachment, signature, policy, and handoff requirements. Forms owns
+those immutable definitions; Forms Runtime persists instances and validation
+evidence. A form Service binding uses `<form-id>/<revision>` and the launcher
+rejects missing, superseded, unpublished, cross-tenant, or invalid definitions.
+
+Portal may discover and invoke those capabilities but cannot write owner
+tables. The owner must revalidate its definition/binding and current
+authorization, produce its normal audit/event state, and make replay after an
+ambiguous response safe. If the capability is absent, the service is
+explainably unavailable. URL-only entries pass through the same launch-time
+availability check and destination validation. Forms Runtime now supplies the
+definition-aware form launcher when both Forms and Forms Runtime are active;
+otherwise Portal continues to fail closed.
+
+## Propagation
+
+`PlatformEvent`, `ActionExecutionRequest`, and `AuditEvent` can carry the
+envelope. Audit persistence stores only its safe projection; platform-event
+outbox serialization preserves it across asynchronous delivery. A module must
+not invent a parallel context dictionary when the shared fields apply.
+
+## First Proof
+
+Committee's `committee.decision_path` capability is the first bounded proof. It
+requires one effective, conflict-free Mandate covering the organization unit
+function, and jurisdiction, an approval reference, fact evidence, versioned legal bases,
+operative result, and reasoning. It emits a reconstructable `FormalDecision`,
+including requested/observed effects and information governance. If a Decision
+registry is installed it persists there; Committee does not take ownership of
+the generic Decision lifecycle.
+
+## Compatibility And Security
+
+- Contract version changes follow Core compatibility policy.
+- Unknown tenant or reference-kind combinations fail closed.
+- Datetimes that affect authority must be timezone-aware.
+- Protected labels, reasoning, evidence inspection links, and source details
+  remain subject to the owning module's access policy.
+- References do not grant access to their targets.
+- Evidence and audit payloads must contain stable references/checksums, not
+  plaintext secrets.

+# Core Interface Pattern Migration
+
+This document records the Core-owned part of the product-wide interface
+pattern-language rollout. The normative product grammar and complete route
+inventory live in the `govoplan` meta repository. Core owns reusable behavior;
+domain modules own their compositions.
+
+## Core Surfaces
+
+| Surface | Pattern | Consequence and provenance contract | Evidence |
+| --- | --- | --- | --- |
+| User settings | Two-zone settings workspace with typed controls and unsaved-change protection | Save actions distinguish busy, unchanged, and test-in-progress states; contextual help resolves through Docs or the hosted fallback | `SettingsPage.tsx`, `test-core-interface-patterns.mjs` |
+| Reusable credentials | Repeated administration with an adaptive create/edit dialog, optional password generator, and destructive confirmation | Secret values are write-only; generated candidates use the browser cryptographic API without a weak fallback and do not replace the field until explicitly confirmed; scope/permission blockers name the required action, responsible actor, and destination; unavailable row actions remain keyboard-explainable | `CredentialEnvelopeManager.tsx`, shared `PasswordField`, `PasswordGeneratorDialog`, `ActionBlockerHint`, `Button`, `TableActionGroup`, and `ConfirmDialog` |
+| Retention policy | Effective-policy editor with inherited source paths and typed, narrowing-only controls | Parent locks and missing write authority are explicit; the save action distinguishes locks, missing target, loading, clean draft, and active save | `RetentionPolicyManagement.tsx`, policy logic tests, `test-core-interface-patterns.mjs` |
+| Module lifecycle | Guided operator projection over durable installer-queue evidence | Preflight, handoff, progress, stale evidence, recovery, and rollback consequences remain visible | Admin module lifecycle tests and the Core installer-queue contract |
+| Shared page frame | Domain-neutral headed page layout used by Core and optional modules | Standalone, workspace, and embedded modes make inset and scroll ownership explicit; sticky heading, rich descriptions, route actions, notices, loading, narrow-layout collapse, and contextual-help identity are centralized; composite administration workspaces may delegate the visible heading to their contributed panel while retaining the same frame; `AdminPageLayout` composes the contract | `PageLayout.tsx`, `page-layout.test.tsx`, Core Settings, Access administration, Docs, Mail bounce processing, Dashboard, Ops, Campaign, and `check-shared-webui-layouts.py` |
+| Full-canvas workspace | Navigation/content and list/detail canvases that own pane geometry and scrolling | Navigation and split variants, primary-pane width, pane-owned or contained scrolling, responsive stacking or navigation collapse, pane labels, and contextual-help identity are centralized without encoding domain navigation | `WorkspaceLayout.tsx`, `workspace-layout.test.tsx`, Core Settings, Access administration, Docs, Organizations, Campaign, Templates, Approvals, and `check-shared-webui-layouts.py`; the raw-workspace exception baseline is empty |
+| Full-height module frame | Outer module landmark and viewport/container sizing | `WorkspaceFrame` centralizes surface, overflow, box sizing, accessible naming, help identity, and application-viewport height so modules do not copy the `100vh - shell` frame | `WorkspaceFrame.tsx`, `layout-primitives.test.tsx`, Dataflow, Workflow, Datasources, Distribution Lists, Notifications, Tasks, Scheduling, Forms, Portal, Projects, Records, and Reporting |
+| Responsive action toolbar | Domain-neutral action and filter grouping for pages, workspaces, editors, and overlays | Density, surface, grouping, flexible space, accessible naming, toolbar help identity, and responsive wrapping are centralized while modules retain action wording, authority, and consequence | `ActionToolbar.tsx`, `layout-primitives.test.tsx`, WYSIWYG, Calendar, Files, Forms, Templates, and the product-wide primitive check |
+| Semantic page and pane action bars | Overview, collection, detail, editor, and workspace intent declared independently from frame geometry; full-canvas panes add workspace/collection/detail/editor scope | Core renders leading Reload from a guarded descriptor; editor persistence owns clean, dirty, invalid, saving, failed, and conflict feedback plus guarded Discard and far-right Save; destructive actions occupy an explicit named boundary; read-only surfaces do not invent Save | `PageActionBar.tsx`, `WorkspaceActionBar.tsx`, `PAGE_LAYOUT_USAGE_GUIDELINES.md`, component and browser conformance, every headed page and full-canvas workspace, and the discovery-based `check-shared-webui-layouts.py` |
+| Catalogue and state composition | Search/filter bars, selectable navigation lists, count badges, and empty/blocked/error panels | Width, surface, wrap, selection geometry, title/description truncation, numeric emphasis, state sizing, tone and action placement are centralized; modules retain query behavior, object state and consequences | `FilterBar.tsx`, `SelectionList.tsx`, `CountBadge.tsx`, `StatePanel.tsx`, `layout-primitives.test.tsx`, and list/detail modules across Cases, Committee, Dataflow, Forms, Notifications, Portal, Postbox, Projects, Records, Reporting, Tasks, Templates, and Workflow |
+| Content and form grids | Equal-column content, field, and native-form geometry | Explicit 1–4 columns, standard gaps, item spans, alignment, and named narrow/workspace/standard/wide collapse points replace generic and module-prefixed copies; unequal domain tracks remain local | `ContentGrid.tsx`, `layout-primitives.test.tsx`, Core dashboard/settings/mail, Calendar dialogs, Forms editor, Datasources, Postbox, Campaign, administration surfaces, and the product-wide primitive check |
+| Content sections | Repeated editor/detail section surfaces | Border, surface, compact/default density, stacked flow and block rhythm are centralized without encoding section contents | `ContentSection.tsx`, `layout-primitives.test.tsx`, Datasources, Distribution Lists, Templates, Dataflow, and Workflow |
+| Form sections | Reusable heading/description/action/content grouping inside forms | Plain, separated, and panel variants centralize hierarchy and narrow action placement without moving validation, permissions, values, or domain wording into Core | `FormSection.tsx`, `layout-primitives.test.tsx`, Addresses contact editing, and Quick Access preferences |
+| Metric groups and drill-downs | Reusable responsive grouping around metric cards with an explicit optional detail affordance | Fixed one-to-five and auto-fit columns, minimum card widths, density, block/inset/zero spacing, and named collapse points replace the product-wide `metric-grid` class and cross-module dashboard overrides; typed link or in-page drill-downs name their destination while summary-only, non-enumerable, derived, or privacy-suppressed values remain inert | `MetricGrid.tsx`, `MetricCard.tsx`, `metric-card.test.tsx`, `layout-primitives.test.tsx`, Core and Dashboard summaries, administration, Campaign, Ops, Files, Search, and dashboard widgets |
+| Description lists | Semantic property and fact presentation | Stacked and inline variants, one-to-five list columns, density, term width, wrapping, and responsive collapse replace both `admin-details-grid` and `detail-list`; `DescriptionItem` preserves native `dt`/`dd` anatomy | `DescriptionList.tsx`, `layout-primitives.test.tsx`, Access and Tenancy administration, Audit, Policy, Campaign reports/imports, Docs, Settings, Ops, and Reporting |
+| Dialog anatomy | Shared outer dialog plus composable body and footer regions | Size and administration variants, body padding, descriptions, notices, fixed action wrapping, native form flow, and section grouping are centralized; focus trapping and stack lifecycle remain unchanged | `Dialog.tsx`, `DialogAnatomy.tsx`, `dialog-focus.test.tsx`, `layout-primitives.test.tsx`, Addresses, Calendar, Records, Datasources, Distribution Lists, Files, and Templates |

+## Boundary
+
+Files and Mail are the first two external consumers of the layered
+server/credential/policy pattern. Their own repositories retain provider
+discovery, transport behavior, authorization, and migration evidence. Remaining
+module surfaces are tracked by bounded module-owned issues under GovOPlaN #11;
+they are not reasons to add sibling-private behavior to Core.
+
+Raw JSON remains permitted only for diagnostics, expert inspection,
+interchange, or conflict evidence. It is not a primary Core configuration
+editor.
+
+New headed pages use `PageLayout`; full-canvas modules use `WorkspaceFrame`
+and, where applicable, `WorkspaceLayout`, so Core owns the frame and pane
+scrolling. Module CSS continues to own unequal domain content layout, never the
+shared page, workspace, toolbar, state, list, filter, metric, section, or graph
+chrome. Retired copies and module-local component definitions are rejected by
+`check-shared-webui-primitives.py`. That check also requires standard dialog
+widths to use `Dialog size` and keeps every remaining domain-specific width in
+a reviewed, decrease-only exception baseline. The companion layout check now
+has zero raw page-frame and zero raw workspace exceptions, discovers semantic
+consumers without a hand-maintained route list, requires semantic action bars

+# Localization And Contextual Help Quality
+
+## Reference Language
+
+German (`de`) is GovOPlaN's first-class reference target. Every translation key
+used by a shipped WebUI must exist in German and English. German completeness is
+a release gate; English remains the source-code fallback language so existing
+literal labels and external developer APIs do not change semantics.
+
+New installations and tenants default to German. Existing system, tenant, and
+user preferences are preserved. The available-language and policy model can
+still select another default or disable a package at the relevant scope.
+
+Explicit high-risk help content and browser acceptance are tracked in
+[Core #284](https://git.add-ideas.de/GovOPlaN/govoplan-core/issues/284).
+
+The platform inventory recognizes both inline locale objects and generated
+catalogs declared as `const de` / `const en`. Its strict mode requires both
+locales and reports `de` explicitly as the reference locale.
+
+## Help Resolution
+
+Every focusable field and action receives a stable derived F1 identity from the
+shared shell, even when the component has no dedicated help text. Resolution
+falls back from field/action to dialog or page and then to the module's visible
+documentation baseline.
+
+Backend manifests publish explicit topic associations first. Core additionally
+associates declared route, navigation, settings, and View surface IDs with the
+module's static user or administrator documentation baseline. Feature modules
+should still add exact `metadata.help_contexts` entries for consequential,
+unfamiliar, policy-controlled, destructive, security-sensitive, or legally
+meaningful fields and actions.
+
+The shared retention-policy editor exposes explicit contexts for each stored
+data category, audit-detail control, lower-level override switch, target
+selector, reload, and save action. The Policy module owns the matching German
+administrator guidance. Retention execution surfaces use separate contexts for
+dry-run, destructive apply, confirmation, and outcome review so F1 opens the
+consequence and recovery guidance closest to the focused control.
+Shared controls may set `helpModuleId` when their documentation owner differs
+from the containing page; the retention editor uses this to resolve Policy help
+from both administration and Campaign surfaces.
+
+The shared reusable-credential manager keeps Access as its documentation owner
+and publishes exact contexts for credential kind, secret replacement/removal,
+module and server restrictions, lower-scope visibility, activation, save, and
+irreversible deletion. This ensures F1 explains secret custody and the effect on
+dependent connections from system, tenant, group, user, and personal surfaces.
+
+The source inventory treats literal `helpContextId` and
+`data-help-context-id` declarations as authored help associations, including a
+native control nested in `FormField`. Dynamic context expressions remain
+separate evidence and generic derived fallbacks remain in the richer-help
+candidate queue.
+
+The generated `help_review_candidates` list is therefore a content-depth queue,
+not a list of controls on which F1 cannot work. It should prioritize:
+
+1. effect, deletion, delivery, retention, disclosure, encryption, and recovery;
+2. identity, representation, mandate, institutional context, and purpose;
+3. valid-time versus recorded-time selection;
+4. provider authority, synchronization, conflict, and outcome unknown;
+5. fields whose consequences are not evident from their label.
+
+The shared browser conformance journey mounts the production Help menu and
+resolver. It proves that F1 uses the focused control rather than only the page,
+maps an exact retention action to Policy-owned administrator documentation,
+retains the page context as fallback for derived actions, exposes an accessible
+modal at narrow widths, closes with Escape, and restores focus to the triggering
+control. Module journeys should add their own exact high-risk mappings; they do
+not need to reimplement the keyboard or dialog mechanics.
+
+## Verification
+
+```bash
+cd /mnt/DATA/git/govoplan
+/mnt/DATA/git/govoplan/.venv/bin/python \
+  tools/inventory/platform-interface-inventory.py \
+  --strict --strict-declarations --strict-endpoints
+```
+
+The check must report:
+
+- reference locale `de` present and complete;
+- no used key missing from `de` or `en`;
+- every field has a resolvable F1 context;
+- no duplicate stable IDs;
+- no undeclared public WebUI surface;
+- no stale runtime route or endpoint declaration.
+
+Browser acceptance is part of the focused workspace gate and can be run alone:
+
+```bash
+cd /mnt/DATA/git/govoplan-core/webui
+npm run test:conformance
+```

+require provider evidence. A supported module with migrations must include
+migration evidence. Signed release catalogs retain and revalidate the
+declaration. The meta manifest check validates repository evidence paths and

+### Source Authority And Provider Operations
+
+Integration maturity and configured authority are independent. The existing
+external-reference maturity ladder describes whether an adapter can discover,
+link, search, read, publish, synchronize, migrate, or replace. A binding must
+also state whether GovOPlaN is native authoritative, the external system is
+authoritative, GovOPlaN keeps a mirror, both sides use governed sync, GovOPlaN
+adds only a governance overlay, or the object is link-only.
+
+`ModuleManifest.external_providers` composes existing contracts rather than
+replacing them. Each declaration describes owned object/field groups, authority modes,
+operations, revisions, freshness, health, limits, idempotency, conflicts,
+outcome-unknown handling, evidence, correction/compensation, reconciliation,
+outage behavior, classification, purpose, retention, and secret requirements.
+Core owns the typed declaration and validation. Connectors and domain modules
+own the actual protocol and domain behavior; configuration packages select the
+effective mode and block missing/incompatible/unhealthy providers; Docs and Ops
+explain the result. Effect-capable declarations fail validation unless their
+retry, concurrency, outcome-unknown, correction, reconciliation, evidence,
+audit, timeout, outage, classification, purpose, retention, and secret behavior
+is explicit.
+
+Declarations are release-time capability claims. Configured state is projected
+separately through `ModuleManifest.external_provider_state_providers`. A state
+provider receives a bounded tenant context and returns one sanitized observation
+per configured binding: stable binding reference, effective authority mode,
+active/configured state, health, freshness, conflict, recovery readiness,
+observation/last-success time, and scalar metrics. Core validates and aggregates
+those observations, isolates provider failures, and never accepts URLs,
+credentials, or arbitrary nested metadata as runtime-state fields. Docs removes
+binding-level detail from ordinary-user projections; Ops may show the full
+sanitized operator projection.
+
+Configuration-package preflight selects the exact requested binding from this
+runtime state before evaluating authority, health, freshness, and recovery. A

+PostgreSQL, Redis, a stable installation identifier, and S3-compatible object
+storage are mandatory. Module durable artifacts must use Core's object-storage
+contract and module-owned opaque key namespaces; node-local paths are limited

+Only the migration command mutates schema. PostgreSQL migration runs acquire a
+deployment-wide advisory lock before module pre-tasks, Alembic, and post-tasks.
+API, worker, and scheduler roles wait for exact configured migration heads and
+fail closed instead of applying migrations during startup.
+
+Runtime roles register identity, software/module composition, queues, heartbeat,
+and drain state in PostgreSQL. Singleton work must use a distributed lease and
+validate its monotonically increasing fencing token at the consequential
+commit. See `STATE_AND_RECOVERY_CONTRACT.md` for the complete contract.
+
+### Recovery Evidence
+
+Operations spanning transactions, object storage, queues, or external systems
+must choose an explicit Core recovery mode: atomic, compensation,
+snapshot-restore, forward-recovery, or irreversible. Plans require verification
+steps and mode-specific recovery material. Use idempotency keys, append-only
+evidence checkpoints, and a runtime fence where work may race across nodes.
+
+The recovery ledger is a shared primitive, not automatic coverage. A module may
+claim its guarantees only after its operation records preconditions before side
+effects, transitions partial/unknown outcomes honestly, and records verified
+completion or recovery. Plaintext secrets must never enter recovery metadata or
+evidence.
+
+For a conclusive external result, modules may commit their local success
+projection and the verified terminal checkpoint in one database transaction via
+`DurableRecoveryOperation.commit_verified_success`. This does not make the
+external provider effect atomic. It prevents a local `succeeded` state from
+becoming authoritative when the recovery evidence chain is damaged or the
+terminal checkpoint cannot commit.

+is shared by every tenant served by that process. Tenant module selection is a
+separate entitlement document in `core_scopes.settings.module_entitlements`:
+
+- a system policy marks each installed module `unavailable`, `available`, or
+  `forced` for one tenant;
+- the tenant selection may enable or disable only available modules;
+- protected platform modules, forced modules, and transitive dependencies stay
+  effective;
+- malformed explicit entitlement fails closed to protected modules, while an
+  absent document preserves the pre-entitlement behavior for upgraded tenants;
+- an optimistic revision prevents concurrent system and tenant administrators
+  from silently replacing each other's changes.
+
+The authenticated platform metadata and module route guard intersect global
+runtime activation with the active tenant's effective entitlement. Entitlement
+does not grant a permission. Access authorization must still allow every API
+operation and resource.
+
+The same boundary applies outside authenticated request handling:
+
+- capability factories retain their owning module, and tenant-scoped capability
+  lookup treats a provider that is unavailable to the tenant as absent;
+- workers partition scheduled scans by tenant before claiming rows;
+- new work is rejected while a module is unavailable, while already accepted
+  durable work remains in provider-owned storage and is reported as
+  `operator_action_required` instead of being dropped or executed;
+- Workflow, Dataflow, event consumers, reconciliation jobs, and external-effect
+  outboxes run inside a tenant execution context, so their optional capability
+  calls inherit the same provider checks;
+- public signed-link modules declare a `public_tenant_resolver`; valid token
+  context is resolved before the route runs and the module entitlement is then
+  enforced without requiring an authenticated principal.
+
+Entitlement resolution uses a bounded process-local cache. A local policy
+mutation invalidates its tenant entry immediately; changes made by another node
+become authoritative after `TENANT_MODULE_ENTITLEMENT_CACHE_TTL_SECONDS`
+(five seconds by default). This is a bounded staleness optimization, not an
+authorization grant: a cache miss or resolution failure fails closed.
+
+Users and groups do not own another module-runtime state. Every WebUI module
+already contributes a root `<module>.module` View surface, so personal and
+group module visibility is expressed through Views. View policy controls who
+may select, assign, edit, derive, or workflow-activate those projections;
+required View assignments can retain required UI. Thus tenant entitlement owns
+operational availability, Views own presentation, and Access owns authority.
+
+Capability-style modules such as Encryption must keep activation separate from
+domain data state. Making Encryption effective only exposes its capability and

+## Connector Runtime Contract
+
+Core defines provider-neutral connector preview and diagnostic primitives in
+`govoplan_core.core.connector_runtime`. The contract keeps optional modules
+decoupled: Connectors owns transport, endpoint discovery, retries, and protocol
+health; the consuming domain module owns mappings, validation, reconciliation,
+and mutations of its records.
+
+Every dry run is bounded and identifies the source revision, source fingerprint,
+immutable input hash, effects, and redacted diagnostics. Its summary must match
+the returned effect list exactly. An apply token is usable only when the preview
+is complete, current, conflict-free, and contains no error diagnostic. Endpoint
+URLs never contain credentials; only credential-envelope references cross the
+contract. Provider-specific details belong in sanitized provenance rather than
+in a shared domain schema.
+
+## Semantic Documentation Subject Contract
+
+Optional modules expose configured artifacts that can be documented through
+the module-scoped `documentation.semantic_subjects.<module_id>` capability.
+Core supplies stable tenant-scoped references, typed nested anchors, safe
+localized descriptors, revision/fingerprint review signals, and explicit
+availability states. Providers remain responsible for authorization and do not
+expose configuration payloads or credentials. Docs discovers the capability
+and owns authored content; it does not import feature internals. See
+`SEMANTIC_DOCUMENTATION_SUBJECTS.md` for the contract and adoption rules.

+# Module Lifecycle Recovery
+
+## Migration Revision Namespace
+
+All enabled module migration directories are assembled into one Alembic graph. Revision IDs are therefore global across Core and every module even though each module owns a separate `migrations/versions` directory. Core validates literal revision declarations before constructing the graph and rejects duplicates with both file paths. A module must assign a new globally unique revision ID; reusing another module's ID can otherwise make Alembic treat an unrelated schema change as already applied or report an ancestor/head overlap.
+
+When correcting a collision that has already reached a database, first verify the schema objects that identify which migration actually ran. Rename the unapplied migration, or transactionally translate the corresponding `alembic_version` row when the applied owner is unambiguous. Never add both colliding IDs as heads or blindly stamp the database.
+
+Package changes and live module-graph changes use Core's durable recovery
+ledger. The local `install.lock` still prevents duplicate work in one runtime
+directory; the database lease `core:module-lifecycle:deployment` is the
+deployment-wide authority across API, installer, worker, and scheduler nodes.
+
+## Declared Boundaries
+
+| Operation | Recovery mode | Completion condition |
+| --- | --- | --- |
+| `module-lifecycle.pre-migration` | compensation | package, WebUI, manifest, and desired-graph evidence match |
+| `module-lifecycle.post-migration` | forward recovery | migration tasks, manifests, desired graph, restart, and health are verified |
+| `module-retirement.destroy-data` | snapshot restore | a hashed, restore-checked backup exists and retirement state is verified |
+| `module-runtime.apply-graph` | compensation | hooks, capability contexts, active graph, and workflow contributions match |
+
+The installer prepares the recovery operation before it captures the database
+snapshot. A full database restore therefore retains the prepared operation and
+its fence instead of erasing the fact that a mutation was attempted. Backup
+artifacts are hashed and sized before any package, migration, or retirement
+effect starts.
+
+Every command boundary records the command source and canonical hashes of the
+redacted command/result records. Credentials, database URLs, command output,
+and package-registry secrets are never copied into recovery evidence.
+
+## Failure And Retry Rules
+
+- A conclusive failure before effects is terminal `failed`.
+- A command or compensatable effect that started but did not complete is
+  `recovery_required`.
+- A lost or unexpected outcome after a migration/external boundary is
+  `outcome_unknown`.
+- A verified package/database rollback becomes `recovered`.
+- A supervised install becomes `succeeded` only after restart and all configured
+  health probes succeed.
+
+An unresolved lifecycle operation blocks every later lifecycle mutation on the
+same deployment fence, even after its execution lease is released. Operators
+must inspect the checkpoint chain and run record, restore or complete the
+declared recovery path, and explicitly reconcile the operation. A new install
+must not be used as an implicit retry.
+
+Live graph changes use the same fence. A non-migrating hook or registry failure
+restores the prior in-process graph and records verified compensation. A failure
+after migrations begin remains unresolved because restoring the process-local
+registry does not reverse database schema effects.
+
+## Operator Evidence
+
+The installer run record contains the recovery operation id, mode, plan hash,
+and current lifecycle status. The Ops recovery view is authoritative for the
+durable state and evidence-chain result. Keep both the run directory and the
+state-service backup evidence until the operation is terminal and the normal
+retention policy permits removal.
+
+Run the module installer rollback drill and recovery-runtime test matrix before
+enabling lifecycle mutation in a new deployment. Shared-state deployments must
+still use immutable release images; the ledger does not make in-place package
+mutation across replicas safe.

+# Page Layout and Action Guidelines
+
+This document defines the binding composition grammar for headed GovOPlaN
+pages. Core owns the reusable anatomy; each module owns its domain actions,
+wording, authorization, consequences, and data state.
+
+## Required Page Frame
+
+- Use `PageLayout` for every headed standalone, workspace, or embedded page.
+- Declare exactly one semantic `archetype`; do not infer page intent from the
+  `mode`, which controls geometry and scroll ownership only.
+- Use `WorkspaceFrame` for a full-height module surface and
+  `WorkspaceLayout` only where navigation/content or list/detail panes are
+  genuinely part of the interaction.
+- Put page-wide feedback in `PageLayout` notices. Use `DismissibleAlert` for a
+  recoverable warning or failure and `StatePanel` when the entire surface is
+  loading, empty, unavailable, or blocked.
+- Do not reproduce shared page padding, heading, toolbar, form-grid, section,
+  table, dialog, or breakpoint CSS in a module.
+
+## Product Side Rail
+
+Module manifests contribute stable navigation surface identifiers, labels,
+paths, icons, and default order. Core owns the side-rail composition and the
+shared `NavigationPreferenceEditor`; modules must not fork this editor or
+persist their own rail ordering.
+
+Navigation preferences are layered in this order: module defaults, system,
+tenant, then user. Each higher layer may reorder or change visibility. System
+and tenant administrators may lock an entry visible; a lower layer can still
+move that entry, but cannot hide it. Personal preferences cannot create locks.
+An unset preference inherits the complete lower layer, while “Use inherited
+order” removes the current layer rather than copying its values. Unknown item
+identifiers remain harmless so uninstalling, disabling, or later reinstalling
+a module does not corrupt the rail.
+
+The platform module response projects module, system, and tenant layer states
+alongside the effective user state. Editors must initialize from the layer
+immediately below the scope they edit, so a system or tenant administrator's
+personal preference is never promoted accidentally. Preference saves refresh
+the platform module projection. View policy, permissions, and tenant module
+entitlements remain independent final visibility gates; changing rail
+preferences never grants access.
+
+## Semantic Page Archetypes
+
+| Archetype | Use when |
+| --- | --- |
+| `overview` | The page summarizes health, metrics, or several peer areas without owning one primary collection or draft. |
+| `collection` | The primary object is a searchable/listable collection and Create, when available, applies to that collection. |
+| `detail` | The page primarily presents one record, report, or immutable projection. |
+| `editor` | The page owns one explicit draft with Save and Discard behavior. |
+| `workspace` | The page coordinates several panes, stages, or task-local operations that cannot honestly be reduced to one record or draft. |
+
+The archetype remains stable for the current interaction. A page may switch
+from `overview` to `editor` when the user explicitly enters configuration
+mode. It must not call a page an editor merely because a dialog or an inline
+filter is editable.
+
+## Page Action Rules
+
+Pass one `PageActionBar` to the `PageLayout` `actions` slot. Full-canvas
+workspaces use the same contract through `WorkspaceActionBar`, with an explicit
+`workspace`, `collection-pane`, `detail-pane`, or `editor-pane` scope. The
+variant makes the surface's intent inspectable and preserves the same keyboard
+and visual order across modules. `ActionToolbar` remains the lower-level
+component for section-local controls; it is not a substitute for a semantic
+page or pane action bar.
+
+| Page kind | Leading group | Trailing group |
+| --- | --- | --- |
+| Overview | Reload when refreshable, then context | Help, then ordinary primary actions |
+| Collection | Reload when refreshable, then collection context such as export | Help, then Create at the far right |
+| Detail | Reload when refreshable, then object context | Help, ordinary primary actions, then a separated destructive group |
+| Editor | Reload only when refresh is a distinct safe operation, then context | Dirty state, Help, ordinary primary actions, separated destructive actions, Discard, then Save at the far right |
+| Workspace | Reload when the coordinated projection can become stale, then task context | Help, ordinary primary actions, then a separated destructive group |
+
+Reload means re-fetch or re-evaluate the current surface. A page declaring
+`refreshable` must provide it, and a non-refreshable page must not use Reload as
+a synonym for Cancel, Reset, or Discard. Reload never silently destroys a dirty
+draft. Create is a collection-wide action and is not duplicated in a
+persistent side panel. Save is present only where the page owns an editable
+draft; a read-only detail page must not display a disabled or inert Save merely
+to fill the slot.
+
+Editor bars always keep Discard and Save visible. Their required `state`
+projection is one of `clean`, `dirty`, `invalid`, `saving`, `save-failed`, or
+`conflict`, and the central component announces it through a live status label.
+Clean and saving states disable both persistence actions; invalid disables Save
+while retaining Discard. Failed saves and conflicts keep the draft recoverable
+and allow an authorized retry after the module has shown the owning error or
+conflict evidence. A module may add a more specific validation, policy, or
+permission blocker. The editor must register its draft with
+`useUnsavedDraftGuard` (or a shared hook that uses the same registration
+contract), so browser unload, route navigation, section changes, Reload, and
+the explicit Discard path cannot silently lose work.
+
+Reload is rendered by Core from a descriptor rather than passed as arbitrary
+button markup. It can project `current`, `stale`, `reloading`, or
+`reload-failed`; `loading` is the shorthand for `reloading`. A failed refresh
+must preserve usable loaded data, expose its stale/failure state, and leave
+Reload available for recovery. Reload goes through the same unsaved-navigation
+guard as route changes.
+
+Destructive page actions use `destructiveActions`; never put a danger action in
+`contextActions` or the ordinary primary group. Core renders a persistent
+visual and semantic boundary before this group. In an editor it precedes the
+Discard/Save pair, keeping Save in the final keyboard and visual position.
+
+`PageActionBar` controls non-editor placement and owns the standard editor
+persistence buttons. Other actions continue to use central
+`Button`, `IconButton`, or `TableActionGroup` components. When an action is
+visible but unavailable because of permission, target, policy, state, or
+validation, keep it in its stable slot and supply `disabledReason`. Do not
+silently hide a normally applicable action.
+
+## Forms and Dialogs
+
+- Compose forms from `FormLayout`/`FormGrid`, `FormSection`, and `FormField`.
+- Use `FieldLabel` through `FormField` for every field that is not genuinely
+  self-explanatory; record justified omissions in the owning UI ledger.
+- Use `Dialog`, `DialogForm`, `DialogSection`, and `DialogActions` for modal
+  work. A dialog can be domain-specific while its anatomy remains central.
+- Use `useUnsavedDraftGuard` for explicit Discard and guarded navigation on an
+  editable page or dialog.
+- Explain irreversible or operationally consequential actions before the
+  commit button, including reversibility and durable evidence.
+
+## Collections and Details
+
+- Use `FilterBar` for collection query controls and `DataGrid` for tabular
+  collections. Keep a single ordered `TableActionGroup` action set per table.
+- Use `MetricGrid`/`MetricCard` for summary measures, `Card` or
+  `ContentSection` for logical sections, and `DescriptionList` for labelled
+  facts.
+- Add a `MetricCard.drilldown` only when the displayed measure has a useful,
+  authorized underlying collection or detail. Name the destination explicitly
+  (for example, “Review failed deliveries”) and preserve the current scope and
+  filters in its `href` or action. The card itself remains non-interactive so
+  the action is visible and keyboard-predictable. Derived, privacy-suppressed,
+  non-enumerable, or purely informational aggregates remain plain metrics;
+  when an ordinarily available drill-down is temporarily blocked, keep its
+  action and provide `disabledReason`.
+- Preserve loaded data after a refresh failure and mark it stale; offer Reload
+  as the recovery action. Distinguish initial loading, empty, unavailable,
+  permission-blocked, conflict, success, and retry states.
+
+## Review Evidence
+
+Every new or changed page or workspace pane must have structural evidence for
+its frame, semantic archetype/scope and slot order, refresh declaration, shared
+component usage, stable disabled actions, dirty guard, destructive boundary,
+and module-owned help identity. Type checks enforce conditional Reload and
+editor persistence props. The product check discovers all consumers, rejects
+undeclared archetypes and `ActionToolbar` panel-header copies, and requires
+semantic actions for every `WorkspaceFrame` route. Browser conformance confirms
+keyboard order, lifecycle changes, accessibility, destructive separation,
+narrow wrapping, and screenshot geometry.

+## Definition Governance
+
+Dataflow and Workflow submit a `DefinitionGovernanceRequest` using only stable
+scope, principal, status, definition-kind, and limit fields. Policy returns a
+standard `PolicyDecision`. System definitions may be inherited as read-only;
+group and user definitions are visible only in matching contexts. Templates
+may be viewed and derived but never run or automated. A derived definition
+passes its pinned ancestor limits back through the request context, and Policy
+applies those limits as ceilings rather than defaults that can be broadened.
+
+When the capability is absent, modules must not silently emulate cross-scope
+inheritance. Their conservative fallback is limited to local tenant
+definitions and disables reuse, derivation, and automation.
+
+## Function Assignment Delegation And Escalation
+
+`FunctionAssignmentGovernanceDecision` is the versioned cross-module contract
+for request/grant review. In addition to the required holder, authority, and
+recipient steps, it returns `delegation_allowed`,
+`maximum_delegation_depth`, `maximum_delegated_validity_days`, and typed
+`FunctionAssignmentEscalationRule` entries. Each escalation entry binds one
+review step to an exact target function and timeout.
+
+The decision is a current ceiling, not durable authorization. IDM must recheck
+the complete assignment-source chain and all recorded decisions before final
+application. An elapsed timeout creates explicit state and evidence; it must
+never be interpreted as approval or as permission to silently substitute an
+approver. Missing providers, malformed rules, invalid chains, or tightened
+limits fail closed with an explainable reason.
+
+## Bounded Impact-Subject Providers
+
+Policy impact previews discover optional subject providers through capability
+names beginning with `policy.impactSubjects.`. The suffix is the stable
+provider ID; for example, Views contributes `policy.impactSubjects.views`.
+Providers implement `PolicyImpactSubjectProvider` and receive a
+`PolicyImpactPopulationRequest` containing the active tenant, policy family,
+an explicit selector, actor scopes, detail-disclosure decision, and a limit of
+at most 500. They return `PolicyImpactSubjectBatch` with unique opaque subject
+references and an explicit `complete`, `sampled`, `truncated`, or `unavailable`
+state. An unavailable batch must explain the gap, and a total may never be
+smaller than the returned subject count.
+
+Core does not scan module data or evaluate domain policy. The owning module
+selects and permission-filters its candidates; Policy compares the current and
+proposed decisions and controls response disclosure. A caller must select one

 The core principle is that a postbox can become a trusted administrative

+
+- `server_envelope_v1` is the recommended default. An institution-selected

+- `plaintext_v1` stores clear content for institutions that explicitly choose

+
+Operational metadata—including subject, routing, participants,
+classifications, timestamps, attachment references, receipts, and retention

+content-protection boundary, not a metadata-anonymity profile.
+
+The standard policy grants new incumbents history since assignment, uses key

+
+## Governed Profile Changes
+
+A profile transition applies to new messages immediately and increments the
+Postbox key epoch. Retained history can remain under the previous profile or be
+migrated. The transition ledger records source and target profiles/vaults,
+authority route, consent and key-holder evidence, quorum, reason, immutable
+configuration snapshot, per-message source and target digest, and outcome.
+
+Plaintext and managed-envelope migrations can use the server-side Encryption
+capability. Managed decrypt, export, and re-encryption operations also create
+Encryption migration records so old envelopes are disposed of through the
+governed provider contract. Any transition to or from E2EE pauses each retained
+message for an approved client transform. The client must return plaintext or
+ciphertext as appropriate, plus evidence and the original content digest;
+Postbox verifies digest continuity before changing the stored representation.
+Leaving E2EE requires user-consent evidence, while changing managed history
+requires institutional key-holder evidence. Dual control can require both.

+
+Collaboration remains connector-first. The product named below never changes
+which GovOPlaN module owns the administrative meaning of the work:
+
+| External family | Initial posture | GovOPlaN semantic owner | Connector-owned boundary |
+| --- | --- | --- | --- |
+| Collabora Online, OnlyOffice, Nextcloud Office | Link an externally edited document and its editing session; import a governed rendition only when required | DMS owns document/version, lock, review, approval, retention, and collaboration-session evidence; Files owns stored bytes | Discovery, endpoint health, WOPI/vendor session exchange, callbacks, and provider object references |
+| Matrix, Mattermost, Rocket.Chat, Nextcloud Talk | Create or link a room/thread for a governed work context; do not mirror all conversation history by default | The initiating Case, Workflow, or Task owns the work-context link and disposition; DMS/Records own retained evidence deliberately captured from it | Room/thread creation, membership synchronization, webhook/event normalization, and stable external links |
+| Jitsi and BigBlueButton | Provision or link a conference for an existing appointment/event | Appointments owns booking intent; Calendar owns event, attendee, invitation, and time semantics | Conference provisioning, join/moderator references, provider lifecycle, and bounded attendance/result callbacks |
+| OpenProject and comparable project suites | Link first, then publish or synchronize selected work packages | Tasks owns GovOPlaN task state; Workflow owns orchestration; Cases own case state and evidence references | Project/work-package lookup, publish/synchronize transport, webhooks, version tokens, and external URLs |
+| Cross-suite activity streams | Consume normalized, bounded events only for an authorized work context | The receiving module decides whether an event changes state or becomes evidence; Audit records the GovOPlaN operation | Provider subscriptions, cursor/checkpoint handling, signature validation, event normalization, and replay protection |
+
+Native collaboration behavior is justified only when GovOPlaN must own the
+semantic state, authorization decision, audit evidence, retention/legal-hold
+rule, or configuration-package fragment. Endpoint profiles, tokens, health,
+protocol clients, provider IDs, retries, and webhook transport remain in
+Connectors (or the owning protocol connector). A feature module consumes a
+Core capability/DTO and must still start and fail explicitly when that optional
+connector is absent; it never imports a provider client.
+
+The minimum hand-off sequences are:
+
+1. **Appointment to conference:** Appointments confirms the booking intent;
+   Calendar creates or updates the event and invitations; an optional
+   conference connector provisions the room idempotently and returns an
+   opaque join reference. Calendar stores that reference with the event, not
+   the provider credential.
+2. **Case or Workflow to collaborative document:** the initiating module asks
+   DMS for a governed document/session; DMS requests an optional office-suite
+   connector session and retains version, lock, approval, and callback
+   evidence. The Case/Workflow keeps only the DMS reference.
+3. **Case, Workflow, or Task to chat:** the semantic owner requests a room or
+   thread with an idempotency key and bounded membership intent. The connector
+   returns an external reference; capturing messages as evidence requires an
+   explicit DMS/Records action and policy decision.
+4. **Task or Workflow to project suite:** Tasks supplies the task payload and
+   Workflow supplies correlation; the OpenProject connector publishes or
+   reconciles the work package and returns versioned external-reference and
+   retry/conflict evidence. Neither consumer writes connector tables.
+
+Every executable collaboration connector must pass the common connector
+contract checks plus a provider-focused minimum proof:
+
+- optional-module startup and partial compositions work without the provider;
+- profile health uses secret references and redacts credentials and remote
+  response bodies;
+- tenant/resource authorization is checked before discovery, provisioning,
+  lookup, synchronization, or evidence capture;
+- dry-run/simulation performs no remote mutation and explains unsupported
+  operations;
+- create/publish calls are idempotent, retries preserve the same external
+  reference, and outcome-unknown or version conflicts remain reconcilable;
+- callbacks/webhooks verify authenticity, tenant/profile binding, replay
+  protection, and bounded payloads;
+- disable/retire behavior revokes new use while preserving non-secret audit and
+  external-reference evidence;
+- Collabora/OnlyOffice prove discovery plus one non-production editing-session
+  round trip; Matrix/Mattermost/Rocket.Chat prove room lookup/create plus one
+  authenticated bounded event; Jitsi/BigBlueButton prove conference
+  provision/cancel; OpenProject proves project/work-package lookup, idempotent
+  publish, and conflict handling.
+
+These are connector acceptance tests, not a claim that those connectors are
+already implemented. Their implementation state remains in the owning
+connector issues and catalogue.

+  adapter. Discovery does not imply conformance or current health.
+
+Callers discover capabilities through the module registry. They must not
+import optional source-module internals.
+
+## Exact Source Identity
+
+`RecordSourceLocator` identifies one tenant, source module, resource type,
+resource ID, and immutable source revision. A source provider must:
+
+1. reject cross-tenant resolution;
+2. require a non-empty purpose;
+3. re-evaluate the caller's current module and object authorization;
+4. resolve exactly the requested revision, never a mutable "current" alias;
+5. return safe display/provenance metadata and a SHA-256 digest when the source
+   has stable bytes or a canonical snapshot;
+6. fail closed when the revision is missing, quarantined, corrupt, or no longer
+   authorized.
+
+Historical Records browsing never revives historical access rights. The
+source's current authorization decision remains authoritative when filing.
+
+## Filing Semantics
+
+`RecordFilingRequest` binds the exact source to a record, purpose, filing
+reason, relationship, institutional context, and idempotency key. Records must
+persist source identity and resolution evidence together with the filing actor,
+represented capacity, valid time, recorded time, and immutable chronology.
+
+An idempotency key may replay only an identical request. A conflicting reuse
+must fail. Filing does not transfer ownership of source content and must not
+silently copy mutable source state.
+
+## Versioning
+
+The Python DTOs and protocols live in `govoplan_core.core.records`. The
+manifest interface `records.filing` starts at `1.0.0`. Incompatible DTO or
+behavior changes require a new interface version and release impact analysis;
+additional optional metadata remains backward compatible.
+
+## Initial Providers
+
+- Files resolves an exact managed `FileVersion`, verifies current Files access
+  and blob integrity, and returns its stored content digest.
+- Cases resolves an exact immutable case revision after current case access and
+  returns a digest of the canonical revision snapshot.
+
+Provider-specific selection UI belongs to the source module. The generic
+Records dialog remains a diagnostic/manual fallback for exact identifiers.
+
+## Archive Transfer Boundary
+
+`RecordTransferPackage` binds a stable package ID, record revision, provider
+profile, canonical manifest, and manifest SHA-256. An archive provider exposes
+`RecordArchiveProviderState` before dispatch and accepts only a
+`RecordArchiveTransferRequest` for a declared healthy profile. Its receipt must
+identify the same package and provider and return one bounded outcome:
+`accepted`, `rejected`, or `outcome_unknown`.
+
+An unknown outcome is never retry-safe. Callers must retain the intent and
+reconcile it against the provider before another effect. Provider state also
+declares authority mode, freshness, limitations, and whether the provider is a
+simulation. Credentials, transport configuration, archive-specific package
+schemas, and custody semantics remain provider-owned.
+
+Records includes `records.archive.simulation` to prove package and receipt
+handling. The simulation is explicitly non-conformant, transfers no custody,
+and cannot be used as evidence of an archive handoff. A real provider requires
+a selected target/profile, provider-specific recovery declaration, and target
+test evidence.
+
+## Form Evidence Boundary
+
+Form attachments use the separate provider-neutral contract in
+`govoplan_core.core.form_evidence`. Forms Runtime requests short-lived,
+purpose-bound upload grants and re-inspects the exact provider-owned evidence
+before final submission. The provider keeps byte storage, quarantine,
+classification, and retention ownership; Forms Runtime stores only immutable
+evidence references and bounded verification results. This contract is not an
+alternative path for Records filing or archive custody.

+Core defines, but does not implement, the optional Search indexing boundary.
+Feature modules register `SearchSourceProvider` implementations for bounded
+backfills and live authorization checks. A provider may additionally implement
+`SearchEventSourceProvider` to translate a committed `PlatformEvent` into one
+or more authoritative `SearchIndexChange` values.
+
+When the Search index-writer capability is active, the platform event worker
+uses the durable consumer identity `search.indexing.v1`. It accepts only public

+The boundary has three non-negotiable rules:
+
+- a source may emit changes only for its registered module, provider, resource

+- Search validates every upsert document before queueing it and rejects secret

+- an index ACL is only a candidate filter. Resources marked for authorization
+  recheck are returned only after the owning source explicitly allows the

+# Semantic Documentation Subjects
+
+## Purpose And Ownership
+
+The semantic-documentation subject contract lets an optional module expose the
+configured artifacts that administrators may document: for example a form, a
+form field, a workflow, or a workflow state. It is a discovery and resolution
+contract, not a second configuration API.
+
+The module that owns an artifact also owns its subject provider, authorization,
+identity, revision, route, and lifecycle semantics. Docs may discover those
+providers through Core and attach authored documentation to their stable
+references. Docs must not import the feature module, read its tables, or copy
+configuration content into a generic index.
+
+This contract is additive to manifest `DocumentationTopic` contributions and
+configured-state `documentation_providers`. Every providing module must retain
+static user and administrator documentation baselines. The baselines explain
+the feature even when the provider is disabled, unavailable, or has no
+configured subjects.
+
+## Identity And Versioning
+
+`SemanticDocumentationSubjectReference` identifies a subject with:
+
+- owning module and tenant;
+- a module-defined subject kind and stable identifier;
+- an optional typed nested anchor, such as `field/registration-number`;
+- the revision and canonical fingerprint observed when documentation was
+  authored or reviewed.
+
+The `stable_key` derives only from identity. A rename or configuration revision
+therefore does not detach existing documentation. A nested anchor has its own
+identity so a field can be documented independently from its form.
+
+Providers must resolve an old reference as one of:
+
+- `available`: the observed revision/fingerprint is still current;
+- `changed`: the same stable subject has changed and may need review;
+- `superseded`: another stable reference replaced it;
+- `missing`: the subject was removed or is no longer resolvable;
+- `temporarily_unavailable`: the provider cannot currently determine state.
+
+Absence is not authorization. A provider returns `None` when the principal may
+not learn whether a subject exists. Core also rejects cross-tenant list and
+resolution requests before calling a provider.
+
+## Safe Projection
+
+Descriptors contain only bounded, explicit presentation fields: localized
+labels and descriptions, breadcrumbs, a local route, audience,
+classification, and required scopes. They must not contain credentials,
+personal data, arbitrary provider metadata, configuration payloads, or the
+authored documentation itself. Routes are application-local and are still
+subject to normal route authorization.
+
+The fingerprint is a review signal, not a concurrency token or a content hash
+that callers may use to reconstruct configuration. Providers should calculate
+it from the smallest canonical JSON projection whose semantic changes require
+documentation review. Volatile timestamps and secrets must be excluded.
+
+## Provider Registration
+
+A provider is registered under its exact module-scoped capability name:
+
+```python
+from govoplan_core.core.modules import CapabilityDocumentation
+from govoplan_core.core.semantic_documentation import (
+    SEMANTIC_DOCUMENTATION_SUBJECT_CONTRACT_VERSION,
+    semantic_documentation_subject_capability,
+)
+
+capability = semantic_documentation_subject_capability("forms")
+
+manifest = ModuleManifest(
+    id="forms",
+    # ...
+    capability_factories={capability: build_semantic_subject_provider},
+    capability_documentation={
+        capability: CapabilityDocumentation(
+            label="Form semantic subjects",
+            summary="Lists authorized configured forms and fields for Docs.",
+            contract_version=SEMANTIC_DOCUMENTATION_SUBJECT_CONTRACT_VERSION,
+            documentation_types=("admin", "user"),
+        )
+    },
+    documentation=(admin_baseline, user_baseline),
+)
+```
+
+The capability is `documentation.semantic_subjects.<module_id>`. Registry
+validation rejects a mismatched owner, missing capability documentation, a
+wrong contract version, or missing static baselines.
+
+`list_semantic_documentation_subjects` performs authorized, paginated discovery
+across installed providers. `resolve_semantic_documentation_subject` targets
+one owner without loading another feature module. Providers must apply the
+current tenant and principal on every call and must not infer visibility from a
+previous list result.
+
+## Lifecycle And Integration Rules
+
+- Keep subject and anchor identifiers stable across display-name and route
+  changes.
+- Return `superseded` only with the replacement reference; do not silently
+  rewrite stored references.
+- Return a reason code for missing or temporarily unavailable subjects without
+  exposing sensitive detail.
+- Reauthorize both discovery and resolution. Stored documentation references
+  confer no access to a live artifact.
+- Treat a changed fingerprint as a request for editorial review. It does not
+  automatically invalidate or publish authored documentation.
+- Removing a feature module leaves references resolvable as provider
+  unavailable. Docs can preserve history without importing the module.
+
+Forms, Workflow, and later modules should implement their subject providers in
+their own repositories. Docs owns the authored semantic-documentation records,
+review workflow, and projection UI.

+# State And Recovery Contract
+
+## State Profiles
+
+Core accepts three runtime state profiles:
+
+| Profile | Runtime placement | Durable storage |
+| --- | --- | --- |
+| `local` | One development process set | Local filesystem is permitted. |
+| `host-shared` | Replicas on one host | One host-shared volume plus PostgreSQL and Redis. |
+| `shared` | Independent hosts | PostgreSQL, Redis, and S3-compatible object storage. |
+
+All replicas in one installation use one stable
+`GOVOPLAN_INSTALLATION_ID`, one immutable module composition, and identical
+database, broker, encryption-key, and object-storage bindings. Core rejects
+replicas with the `local` profile and rejects `shared` without PostgreSQL,
+Redis, S3, and a non-default installation identifier.
+
+`FILE_STORAGE_S3_ENDPOINT_TRUSTED=true` is an explicit deployment trust
+declaration for a clean HTTPS S3 origin. It does not authorize a
+user-controlled connector endpoint and it is separate from installer-managed
+Garage's exact endpoint trust.
+
+## Object Storage
+
+`govoplan_core.core.object_storage` is the shared backend contract for durable
+module artifacts. It provides bounded read/write/list/stat/delete operations
+for local and S3-compatible storage. Modules own their object-key namespace and
+business metadata; Core does not interpret module files.
+
+`stat` and `list_objects` return object size plus a UTC `modified_at` value when
+the backend can prove it. Reconciliation and retention code may use that value
+for conservative grace periods, but must treat a missing timestamp as
+ineligible for automatic deletion rather than guessing an age.
+
+Rules for modules:
+
+- Store only opaque object keys in business records, never local absolute
+  paths.
+- Use node-local directories only for temporary materialization.
+- Verify expected size and digest before consuming consequential artifacts.
+- If object creation precedes database commit, compensate successfully created
+  objects on failure.
+- If object deletion fails, retain the database reference and report a retryable
+  failure rather than claiming deletion.
+- Define an orphan-inventory strategy for hard process loss between object
+  creation and metadata commit.
+
+The Files module delegates its backend implementation to this Core contract.
+Campaign generated EML artifacts use a Campaign-owned object prefix and are
+read by workers through the same shared backend.
+
+## Runtime Nodes And Leases
+
+API and worker incarnations register in `core_runtime_nodes` with role,
+software version, module-composition hash, queues, start time, and heartbeat.
+The registration identity includes a process incarnation so a stale process
+cannot update a replacement's row.
+
+Worker metadata also records the orchestrator pool and declared concurrency.
+Every Celery prefork child disposes the SQLAlchemy pool inherited from its
+parent and creates a process-local pool before handling work. Deployment
+rendering must therefore budget one database pool for the worker parent and
+each child. Ops compares active queue ownership, software versions, and the
+order-independent module-composition hash with the graph loaded by the API.
+
+Drain is durable operator intent:
+
+- an API enters not-ready state after observing drain;
+- a worker cancels queue consumers after observing drain;
+- cancellation returns an eligible draining node to active state;
+- clean shutdown marks the matching incarnation stopped.
+
+Coordination loss also fails closed. An API reports
+`coordination_unavailable` from `/health/ready` until a heartbeat succeeds
+again. A worker cancels its local queue consumers on any heartbeat or database
+failure and only resumes them after its existing incarnation heartbeats
+successfully. It never re-registers from the heartbeat path, so a stale worker
+cannot reclaim a node identity from its replacement.
+
+`core_distributed_leases` provides installation/resource uniqueness, expiry,
+holder incarnation, and monotonically increasing fencing tokens. Lease expiry
+does not make an old process harmless by itself: code performing an effect must
+assert its exact fence before commit. `govoplan_core.commands.fenced_run`
+renews a lease around a subprocess and terminates the child when the lease is
+lost. The deployment profiles use it for the singleton scheduler.
+
+## Migration Ordering
+
+Only `govoplan_core.commands.init_db` mutates schema. On PostgreSQL it acquires
+a deterministic installation/track advisory lock before pre-migration tasks,
+Alembic, and post-migration tasks. The lock is session-scoped and therefore
+released if the migration process dies.
+
+Runtime roles run `govoplan_core.commands.wait_for_database`. It waits until
+the database has exactly the configured, dependency-resolved Core/module
+Alembic heads and never upgrades schema. Cross-module `depends_on` revisions
+therefore do not leave runtime roles waiting for a branch marker Alembic has
+correctly consumed. This permits a migration Job and runtime Deployments to be
+submitted together while keeping startup fail-closed.
+
+Runtime coordination records the installed `govoplan-core` distribution
+version for API, worker and scheduler roles. FastAPI/OpenAPI metadata versions
+are presentation metadata and must not be used as deployable software identity;
+mixing the two would create a false version-skew readiness failure.
+
+## Recovery Ledger
+
+`govoplan_core.core.recovery` provides a durable operation and evidence
+contract. Recovery modes are:
+
+- `atomic`: one database transaction, no external effect;
+- `compensation`: explicit inverse actions;
+- `snapshot_restore`: separately verified backup reference;
+- `forward_recovery`: repair/resume the current version;
+- `irreversible`: explicit approval, no automated recovery claim.
+
+Every plan requires verification steps. Mode-specific evidence is mandatory.
+Operations bind an idempotency key to a canonical request hash, may bind a
+runtime fencing token, and emit append-only hash-chained checkpoints. Backup
+and approval references are part of the hashed plan evidence. Every low-level
+state transition and checkpoint append revalidates the operation's recorded
+fence while holding the operation row lock. Plaintext secrets are rejected
+from metadata and evidence.
+
+The state machine makes partial and uncertain outcomes visible. A non-atomic
+running operation cannot transition directly to ordinary failure, and success
+or recovery requires explicit verified checks. Ops projects states requiring
+attention, but module behavior gains this guarantee only after it adopts the
+ledger around its own side effects.
+
+## Recovery Boundary
+
+Application/configuration rollback and database rollback are not equivalent.
+Once an incompatible migration starts, old code may be unsafe even if its image
+is available. Deployment automation must switch to forward recovery unless a
+coordinated and verified database/object/key backup is restored.
+
+Core does not create production database backups. The deployment owner must
+provide backup, retention, encryption, restore verification, and recovery-point
+coordination for PostgreSQL, object storage, and encryption keys. The canonical
+operator procedure is documented in
+`govoplan/docs/operations/RECOVERY_AND_ROLLBACK_GUARANTEES.md`.

+# Tabular Source Preview Contract
+
+Core defines provider-neutral DTOs for optional tabular source providers. A
+source declares whether it is live, cached, file-backed, or static; its schema
+and immutable fingerprint; structured health; and the exact projection,
+pagination, filter, aggregation, and sorting operations that the provider can
+push down. Consumers must not infer pushdown support from a provider name.
+
+Every preview request carries independent row, byte, and elapsed-time budgets.
+A provider may tighten these values but must return its effective limits,
+returned byte count, elapsed milliseconds, truncation state, and structured
+diagnostics. Equivalent fields on the Datasources read request and result
+preserve that evidence when a live source is consumed through the catalogue.
+A row that cannot fit within the byte budget fails explicitly rather than
+leaking a partial value. Timeout, stale fingerprint, unavailable source, and
+authorization failures remain distinct provider-neutral errors.
+
+Connector health and preview diagnostics must contain no credentials, endpoint
+userinfo, row values, or unbounded remote error bodies. A Datasource origin
+preserves this contract so registration and staging do not erase source mode,
+health, pushdown, or preview-limit evidence.

+# Template And Generated Artifact Capability Contracts
+
+Core defines provider-neutral contracts for optional template libraries and
+generated artifact storage. Core does not render templates or store generated
+files itself.
+
+## Templates
+
+- `templates.catalog` lists typed, versioned template references and checks a
+  consumer's available fields, usage, and output format.
+- `templates.renderer` accepts a `TemplateRenderRequest` containing pinned
+  input data and returns immutable render evidence plus an artifact reference.
+
+The DTOs contain identifiers, hashes, plain mappings, and scalar metadata. They
+do not expose Template ORM models or require Campaign, Distribution Lists,
+Addresses, Reporting, Forms, or Mail.
+
+## Generated Artifacts
+
+`files.artifact_store` accepts a `ManagedArtifactWriteRequest` and returns a
+`ManagedArtifactRef`. Producers supply bytes, a safe filename/content type,
+idempotency key, and non-secret provenance. Files owns path normalization,
+authorization, versions, storage, and download behavior.
+
+Consumers must discover both contracts through the module registry and degrade
+only the unavailable path. A template renderer may return a bounded download
+when Files is absent. A caller must not infer successful external delivery from
+successful rendering or artifact persistence.

+# Temporal Data Context
+
+GovOPlaN exposes one read context for data validity and system knowledge. The
+calendar control in the authenticated titlebar applies that context to
+supported list and detail reads for the current account and tenant.
+
+## Two Independent Axes
+
+- **Valid time** answers when a fact applied in the represented domain.
+- **Recorded time** answers what the system had recorded by a particular
+  instant.
+
+The default is data valid now under the latest recorded state. `At time`
+selects a valid-time instant. `All` removes the valid-time interval filter but
+still uses the selected recorded state. The optional recorded-state cutoff can
+be combined with any valid-time mode, which keeps correction history distinct
+from changes in real-world validity.
+
+An interval is half open: `valid_from <= instant < valid_to`. A revision belongs
+to a recorded-state snapshot when `recorded_at <= cutoff` and it was not
+superseded at or before that cutoff.
+
+## Security And Mutation Rules
+
+The temporal data context is a read projection, not an authorization context.
+Authentication, permissions, active delegations, tenant boundaries, module
+policy, and maintenance controls are always evaluated under current security
+state. A historical projection never restores an expired permission.
+
+The context also does not supply mutation dates. Writes continue to target the
+current lifecycle revision and must carry their explicit valid/effective dates,
+expected revision, reason, and evidence where the owning contract requires
+them. A screen showing historical data must not silently turn a normal edit
+into a historical correction.
+
+## HTTP Contract
+
+Core accepts these request headers:
+
+| Header | Meaning |
+| --- | --- |
+| `X-Govoplan-Validity-Mode` | `current`, `at`, or `all` |
+| `X-Govoplan-Valid-At` | Timezone-aware ISO 8601 instant required by `at` |
+| `X-Govoplan-Recorded-At` | Optional timezone-aware system-knowledge cutoff |
+
+Invalid or naive timestamps fail with HTTP 400. Responses expose the resolved
+mode and evaluated instant. Conditional JSON responses vary by all three
+request headers, and the shared WebUI API client includes them in request
+deduplication and conditional-cache keys.
+
+## Module Adoption
+
+Revision-owning modules apply
+`govoplan_core.db.temporal.apply_temporal_revision_filter` only to read queries
+that are meant to follow the platform context. Explicit version references and
+explicit resolver `effective_at` arguments take precedence. Current-row
+lookups used for optimistic concurrency, authorization, routing, effects, or
+other mutations must remain explicit and context-independent.
+
+The initial bitemporal adoption covers Decisions, Mandates, Parties, and
+Services. Their immutable revisions have indexed valid, recorded, and
+superseded timestamps. Modules with effective-dated security records or
+recorded-only revision histories require separate display-query adoption so
+the global selector cannot affect current authorization or execution.
+
+The WebUI selection is stored in session storage per account and tenant. A
+change remounts the active module route so existing page loaders issue a fresh
+request. Returning both axes to their defaults removes the stored selection.

+# WebUI Theme Contract
+
+GovOPlaN supports `system`, `light`, and `dark` as persisted user preferences.
+`system` follows `prefers-color-scheme` live; it is not resolved permanently at
+save time. Core applies the resolved mode through `data-theme` on the document
+root and exposes the selected preference through `data-theme-preference`.
+Each user may also choose a validated `default`, `civic_blue`, `forest`, or
+`plum` accent palette. Core applies it through `data-palette`; every module
+inherits the result through semantic tokens without module-specific CSS.
+
+## Ownership
+
+- Core owns semantic CSS tokens, native `color-scheme`, preference persistence,
+  the Settings selector, and the shared shell.
+- Modules consume semantic tokens such as `--surface`, `--text`, `--line`, and
+  the status token families. They may define domain aliases whose values resolve
+  to shared tokens.
+- Palette defaults form a provenance chain: system, tenant, then an explicit
+  user choice. Invalid stored values are ignored. Reset means inheritance and
+  does not copy the current parent value into the child scope.
+- A policy lock is separate from the default. A system lock wins over every
+  child scope; otherwise a tenant lock suppresses a personal override. The
+  authenticated profile reports the effective palette, source, inherited
+  palette, and lock state.
+- Advanced personal overrides are a separately governed surface. The system
+  must opt in, a tenant may inherit or block that decision, and palette locks
+  always suppress overrides. Changing either policy requires
+  `admin:policies:write` in addition to the owning settings permission.
+
+## Palette safety and scope
+
+The Settings preview shows the chosen or inherited accent in every applicable
+light/dark preview before Save. Presets are checked for WCAG AA contrast in the
+theme contract. When policy permits, the shared advanced editor can atomically
+override accent, surface, and semantic status pairs for both modes. Every
+foreground/background pair must meet WCAG AA contrast, and success,
+information, warning, and danger colors must remain distinct. Invalid stored
+documents fail closed and are not partially applied.
+
+Import and export use the exact versioned JSON schema `schema_version: "1"`.
+Both `light` and `dark` must contain every supported token exactly once as a
+six-digit hex value. Import changes only the local draft; Save persists the
+whole document. Removing overrides returns to palette and policy inheritance.
+The system default is disabled so upgrades do not unexpectedly admit arbitrary
+branding. Tenant `null` means inherit, `false` blocks, and `true` is accepted
+only while the system permits overrides.
+
+Do not introduce fixed foreground/background colors in a module merely to make
+one mode look correct. Add or reuse a semantic Core token, then define both
+light and dark values. Bitmap content and externally authored HTML are exempt,
+but their surrounding controls must still use the shared tokens.
+
+`npm run test:theme-contract` verifies root mode/palette behavior, preset and
+custom-override validation/application, and representative
+Campaign, Calendar, Files, and Mail token consumption. The check runs before a
+production WebUI build.

+# Ticket Integration Capability Contracts
+
+Core owns two narrow, optional contracts that let the Tickets module compose
+with policy and formal-procedure modules without importing either one. Tickets
+remains the authority for operational ticket identity, lifecycle, assignment,
+comments, links, and immutable history.
+
+## Capability Names
+
+- `tickets.routing` optionally supplies a `TicketRoutingProvider`.
+- `tickets.case_escalation` optionally supplies a
+  `TicketCaseEscalationProvider`.
+
+Both contracts are version 1 and are defined in
+`govoplan_core.core.tickets`. Registry helpers return `None` when a capability
+is absent or has the wrong shape, so optional-module absence is normal runtime
+state rather than a startup failure.
+
+## Routing
+
+Tickets sends a bounded, tenant-scoped `TicketRoutingRequest` containing the
+ticket reference, type, priority, title, receive time, optional queue hint, and
+non-secret attributes. The provider returns its identity and may return a queue
+reference, timezone-aware service target, human-readable explanation, and
+bounded metadata.
+
+The provider is advisory. Tickets snapshots any returned queue and target into
+its own record and history. An absent provider, a no-match plan, or an absent
+queue must not prevent ticket intake; authorized staff can route manually.
+Providers must not persist a second ticket lifecycle.
+
+## Case Escalation
+
+Tickets sends a `TicketCaseEscalationCommand` with stable tenant, ticket, and
+display references, the requested Case type, actor-visible handoff note,
+timezone-aware occurrence time, and an idempotency key. The provider returns a
+stable Case identifier, number, bounded application-relative URL, replay flag,
+and bounded metadata.
+
+Providers must:
+
+- recheck tenant and Case-creation authorization;
+- reject an absent or inactive requested Case type;
+- make identical retries resolve the same Case;
+- preserve the Ticket reference in governed Case context; and
+- return only an application-relative path, never an untrusted external URL.
+
+Tickets records the result and its own escalation evidence. Cases remains the
+authority for the formal procedure; Tickets remains the authority for the
+operational request. Creating a Case does not merge or silently close either
+lifecycle.
+
+## Failure And Transaction Semantics
+
+Capability calls receive the caller's active persistence session so a concrete
+provider can participate in the same unit of work. Authorization and validation
+errors fail the requested routing/escalation mutation explicitly. The caller
+must still apply its own permission checks, tenant boundary, replay protection,
+and immutable evidence rules.

+# WebUI Loading And Bundle Budgets
+
+The Core WebUI host owns the loading boundary for installed module packages.
+Vite discovers configured packages at build time, but emits an asynchronous
+loader for each package's `src/module.ts` contribution descriptor. At runtime,
+Core imports only descriptors whose backend manifests are enabled and identify
+the matching `frontend.package_name`.
+
+The direct descriptor entry is intentional. A package root may re-export pages
+for consumers; importing that barrel as module wiring can cause those pages to
+be evaluated before navigation. Route pages and substantial panels should use
+`React.lazy`, and Core wraps routes in the shared loading/error boundary.
+
+## Enforced Budgets
+
+`webui/bundle-budget.json` contains the production limits:
+
+| Measurement | Raw limit | Gzip limit |
+| --- | ---: | ---: |
+| Initial JavaScript static import closure | 512 KiB | 160 KiB |
+| Largest individual asynchronous JavaScript chunk | 384 KiB | 110 KiB |
+
+`npm run build` writes a Vite manifest, measures the entry and its recursive
+static imports, writes `dist/bundle-metrics.json`, and fails when either budget
+is exceeded. `npm run test:module-permutations` applies the same gate to every
+permutation and records the collected results in
+`dist/module-permutation-bundle-metrics.json`. In CI, each result is also added
+to the step summary.
+
+Budgets are limits, not targets. A change that approaches a limit should add a
+new lazy boundary or remove unnecessary entry code instead of raising the
+limit without measurement and review.
+
+## 2026-07-30 Baseline
+
+Measurements use the same full-product source tree and Node 22 runtime. The
+post-change build additionally includes the Search module in the default and
+full-product sets.
+
+| Initial-load measurement | Before | After | Reduction |
+| --- | ---: | ---: | ---: |
+| JavaScript assets in initial static closure | 1 | 1 | 0% |
+| Raw JavaScript | 1,387,043 B | 453,769 B | 67.3% |
+| Gzip level 9 | 364,767 B | 141,725 B | 61.1% |
+| Brotli quality 11 | 254,797 B | 106,701 B | 58.1% |
+| Parse proxy median | 18.776 ms | 7.750 ms | 58.7% |
+| Parse proxy p95 | 21.980 ms | 8.739 ms | 60.2% |
+
+The parse proxy constructs a fresh `node:vm` `SourceTextModule` from the entry
+source 30 times with a randomized source marker. It is useful for a controlled
+before/after comparison, but is not enforced in CI because absolute timings
+vary across runners. Transfer budgets use deterministic raw and gzip byte
+counts.
+
+The first budgeted full-product build reported:
+
+- initial JavaScript: 453,769 B raw / 141,725 B gzip;
+- largest async chunk: `CampaignWorkspace`, 353,724 B raw / 98,142 B gzip.
+
+## Verification
+
+```bash
+cd /mnt/DATA/git/govoplan-core/webui
+npm run build
+npm run check:bundle-budget
+npm run test:module-permutations
+```
+
+The build gate also catches accidental eager imports: a page pulled into the
+entry closure consumes the initial budget, while an oversized page or module
+descriptor consumes the asynchronous chunk budget.

+Core discovers a module contribution from `src/module.ts` when `node_modules`
+links directly to a module's `webui` package. Tagged release dependencies are
+installed from repository-root packages and expose the same contribution at
+`webui/src/module.ts`. The Vite registry accepts both layouts and imports the
+contribution descriptor directly so route-level lazy loading is preserved.
+
+A release package is invalid if neither entry exists. The module-permutation CI
+matrix builds source-linked and installed release compositions; it must not fall
+back to a package root barrel because that would eagerly pull module pages into
+the shell bundle.
