+
+All optional WebUI modules use the Core API client. Its bounded in-memory caches
+are an optimization, never an authorization mechanism. The backend must check
+the current principal, tenant, and permissions even for conditional GETs.
+
+- Identical simultaneous safe requests can share one network request. Requests
+  with caller-owned cancellation are independent.
+- Responses allowing reuse have at most a 750 ms recent-response window.
+  `no-store` and `Vary: *` responses are not retained. `no-cache` and zero-age
+  responses require a server check; permitted ETags retain conditional GET
+  support without bypassing authorization. This follows the relevant
+  [HTTP cache-control semantics](https://www.rfc-editor.org/rfc/rfc9111.html#section-5.2.2).
+- Explicit `cache: "no-store"`, `"reload"`, or `"no-cache"` reads bypass older
+  response data and supersede older requests for that resource. Reload is not a
+  mutation. Owning read helpers must pass these options through pagination.
+- Writes invalidate caches before execution and again on settlement, including
+  failures whose server outcome may be uncertain. Reads started before or
+  during the write cannot seed reusable data after it finishes.
+- The shell calls `clearApiReadCache()` before explicit auth updates and when
+  refreshing authoritative session data. API-settings changes, clearing the
+  token, authentication expiry, and changes to the paired session/CSRF cookie
+  also invalidate both stored and in-flight reuse. Cookie observation also
+  covers sign-in/out in another tab; it does not read the HttpOnly session token.
+- Interactive sign-in and sign-out clear a previously saved automation key.
+  Explicit key-based connection settings still select the key's identity;
+  profile-only updates preserve settings identity to avoid reload loops.
+- Expired responses from superseded reads or downloads do not trigger a login
+  prompt in a newer session.
+- Every completion (including 304) must still own its cache slot and generation
+  before storing anything. An old caller may receive its own result, so feature
+  components must continue guarding displayed state against obsolete requests.
+
+Regression coverage: `npm run test:api-client-cache` uses the real client and
+isolated network fixtures. No live API or account data is involved.

+# Disposable resource-bounded operations
+
+`security.bounded_process.run_bounded_operation` runs a trusted, importable,
+module-level `bytes -> bytes` function in a fresh interpreter. Core owns the
+process lifecycle, not the business parser. Owners retain authorization,
+sessions, provider reads, idempotency and persistence in the parent and pass
+only explicit bounded data. Never accept the operation, module or source path
+from a client. Use `security.worker_payload` for typed values; it does not use
+pickle, arbitrary constructors or JSON object hooks.
+
+The runner requires POSIX process groups, `waitid(WNOWAIT)` and resource limits.
+Unsupported controls fail closed; there is no in-process fallback. The child
+uses `-I -B`, a fixed minimal environment, `/` as working directory, closed
+inherited descriptors and a new process session. Limits are installed before
+the owning module is imported. Installed dependencies must support isolated
+Python imports; development `PYTHONPATH` alone is insufficient.
+
+`ProcessLimits` specifies wall-clock seconds (including child startup), CPU
+seconds, virtual address space, input/output pipe bytes and maximum regular-file
+size. Defaults are 10 seconds wall/CPU, 256 MiB address space, 8 MiB input and
+output, and no regular-file output. Wall/CPU limits are at most 600 seconds,
+memory 64 MiB–8 GiB, pipe limits 1 byte–256 MiB, and file size 0–2 GiB. Owners
+must document their tighter functional limits; a transport cap does not replace
+row, archive expansion, item-count or artifact limits.
+
+Admission is non-queuing. `GOVOPLAN_ISOLATED_PROCESS_CONCURRENCY` defaults to 1
+(range 1–16) and applies across these operations **within each API/worker
+process**. Multiply capacity and memory budgets by the number of API/worker
+processes when sizing an installation. This is not a fleet-wide semaphore,
+cgroup quota, filesystem/network sandbox or permission to run arbitrary code.
+`RLIMIT_FSIZE` is per file, not a total disk quota. Owners creating staged files
+must enforce cumulative quotas and clean up their own private directories.
+
+Owners preparing bounded local snapshots can enter
+`bounded_operation_admission()` before preparation and pass its token as
+`admission=` to the runner. This reuses shared capacity rather than reserving a
+second slot. Tokens belong to their active context, thread and process; expired,
+cross-thread and overlapping reuse fail. Preparation exceptions release the
+slot without launching a child. Never hold admission while waiting for a user;
+parent-side preparation still requires explicit I/O and byte bounds.
+
+The parent concurrently drains stdout/stderr while writing input. Output is
+bounded during reading, stderr is discarded and capped at 64 KiB, and raw child
+tracebacks are never returned. Every success, exception, timeout, cancellation
+and callback failure kills the owned process group before reaping its leader,
+including descendants which close their inherited pipes. A module-level child
+handler must return bytes; it must not print logs/progress to stdout.
+
+The optional `cancelled` callback runs in the parent at most roughly every
+50 ms while waiting. It must be fast and must not return an awaitable. It may
+also service a module-owned bounded progress protocol; exceptions terminate
+the child and propagate. There is no fabricated progress for killed work.
+`ProcessBudgetError.code` distinguishes busy, cancelled, timeout, CPU, memory,
+input/output limits, unavailable controls and worker failure. Owners map these
+to their existing structured diagnostics and recovery semantics.
+
+The private typed-data codec supports null, booleans, strings, bytes, integers,
+floats, Decimal, UUID, date/time/datetime, lists, tuples and string-keyed maps.
+It rejects unsupported objects, malformed/trailing bytes, duplicate keys,
+excess depth (64) and node counts (1,000,000). Operation DTOs remain owner
+contracts and require owner validation. Do not persist this private wire format
+or use it as a public API.
+
+Tests use real child processes for catastrophic regex, memory exhaustion,
+noisy output, exact limits, cancellation, closed-pipe hangs and descendant
+cleanup. These are local process regression tests, not production concurrent
+load certification. Operators still need target Linux/cgroup, cancellation,
+worker-count, memory and disk-quota evidence before raising concurrency.

+
+## Action Visibility and Constrained Containers
+
+Action tracks reserve the width of actual buttons, disabled-action wrappers,
+reserved empty-state slots, gaps, and cell padding. A historic `width: 72`
+preference therefore cannot clip a four-button action group. Ordinary data text
+does not participate in this content measurement; long field values do not
+silently widen all tracks. Changes to the rendered action set are remeasured.
+
+`TableActionButton` remains a compact 36 px control, including the Add action
+in an empty grid. Never stretch it with a last-column `.btn { width: 100% }`
+rule. Its shared maximum width and fixed flex basis protect against broad
+consumer button rules, which can otherwise feed stretched widths back into
+action-track measurement and consume the data area.
+
+When the full group needs more than half the scroll viewport, its measured
+minimum is capped at half the viewport and the group wraps. Explicit hard
+minima remain authoritative. Custom action groups should use wrapping-capable
+flex layouts and semantic groups, preferably composing `TableActionGroup`.
+
+The grid's physical width matches its pixel tracks, including horizontal
+overflow, so right-sticky actions remain inside the correct scroll bounds.
+If explicitly wide or persisted sticky tracks would obscure the readable data
+area, horizontal stickiness is released until space returns. No columns or
+actions are hidden: the labelled scroll region is focusable and supports native
+keyboard scrolling. Vertical header stickiness remains available.
+
+## Resizing Controls
+
+Drag a resize handle with a mouse, pen, or touch pointer. Pointer capture keeps
+the drag active when it leaves the handle. Escape or pointer cancellation
+restores the layout before that drag; releasing the pointer commits it. Losing
+window focus ends a drag without leaving the table stuck in resizing mode.
+
+Each handle is a focusable vertical separator exposing its current and allowed
+widths. Left/Right changes its width by 10 px; Shift+Left/Right uses 40 px. Enter
+or a double-click resets that column's explicit override to the declared sizing
+rules. Other columns retain their preferences, so cover/compensation constraints
+still apply. These operations only change personal browser layout, never rows.

+## Refreshes, edits and table rendering
+
+The shell runs at most one module-load refresh per authority generation. Multiple
+invalidations coalesce into one trailing refresh; stale results and errors cannot
+replace a newer generation. Focus refreshes are throttled to five seconds and
+focus/visibility refreshes on hidden pages are suppressed; explicit module
+invalidations still trigger a read. Authentication/tenant reset disposes the
+previous controller. Authentication and authorization checks are not cached away.
+
+Editable modules must reconcile a save against the submitted draft and accepted
+server revision: edits made while a request is pending remain dirty. Completion
+must be fenced by security-relevant authority and selection, not merely an auth
+object's reference identity. A harmless profile refresh must not discard an
+accepted newly created ID and invite a duplicate create. An old account's mutation
+continuation must not reload its catalogue into the current account's page.
+
+DataGrid precomputes first-occurrence row indices once for client sorting and
+filtering. Duplicate object references, primitive values, `NaN` and sparse arrays
+retain `Array.indexOf` behavior. Comparator order, visible pagination, server-side
+pagination, sizing and resize rules are unchanged. Do not replace this with a
+last-occurrence map or change ordering as a side effect of an optimization.
+
+## Conditional responses
+
+The shared JSON GET middleware performs route handling, including authorization,
+before considering `If-None-Match`. It buffers only responses up to 1 MiB for a
+body-derived ETag. Known larger responses bypass buffering; an unknown-length
+stream crossing that limit replays its exact prefix and streams the remainder.
+No data is truncated and no large joined copy is created. The crossing chunk is
+already producer-owned: this is not a process-wide or route-output memory limit.
+Empty chunks do not accumulate. Large responses may no longer receive a
+middleware-generated ETag/304; explicit route ETags remain intact. Small-response
+cache semantics and credential/language/context `Vary` fields are retained.
+
+## Shared helpers and concurrency
+
+Central helpers replace exact live-code duplicates only. Actor precedence,
+whitespace handling and service-account differences remain explicit owner choices;
+historical migration code is not redirected to mutable runtime helpers. Connector
+search ACL token projection keeps its first-seen ordering and existing 500-token
+cap, stopping work once that cap is reached. Provider schemas are inferred in one
+pass without storing a second list of every column value.
+
+The keyed-list three-way merge retains insertion anchors when unrelated fields
+change. Concurrent additions use deterministic ordering; contradictory anchors
+produce a collection-order conflict instead of silently relocating an item.
+No existing endpoint is newly opted into merge behavior by this change.
+
+SQL JSON authorization predicates support the explicitly tested SQLite and
+PostgreSQL dialects, retain exact string membership and reject unsupported
+dialects. Apply tenant and authorization predicates before counting/pagination;
+never page a broader result first and filter away unauthorized records afterward.
+SQLite execution and PostgreSQL SQL compilation are not substitutes for a
+deployment's PostgreSQL concurrency and representative-data load tests.

+## Migration connection URLs
+
+Alembic preserves the configured database URL exactly in online and offline
+migration modes, including percent-encoded credentials and PostgreSQL Unix-socket
+paths. Escaping applies only at its ConfigParser boundary; operators must not

+Side-rail customization uses the shared `NavigationPreferenceEditor` for system,
+tenant, personal, and View layouts. Modules and labelled separators share one
+ordered list, with pointer drag-and-drop, keyboard reordering, and explicit

+mounting the editor does not create a draft change. See
+`NAVIGATION_LAYOUT_CONTRACT.md` for inheritance, locked items, optional-module
+preservation, and collapsed-rail grouping.
+
+Action columns use `TableActionGroup` or declare `columnType: "actions"` when

+allocation, persistent resizing, and local horizontal scrolling; consumers must

+`DATAGRID_SIZING_CONTRACT.md`. Dialog forms use `DialogForm` and `FormGrid` inside
+the shared size-bounded dialog. Do not add a content minimum wider than the

+In `FormGrid` and `FormLayout`, direct `FormField` and `ToggleSwitch` items

+`FrontendModule.product_surfaces` is the versioned product-composition contract
+for stable identities that may have one or more technical owners. A contribution

+stable entry path, owner route and View surfaces, supported task/reader/admin/
+operator presentations, authorization requirements, capabilities, search
+sources, help contexts, documentation topics, migration aliases, and standard
+unavailable/degraded explanations.
+
+Core validates every reference against the owning manifest. Contributors that
+share an identity must agree on its common product metadata and entry path;
+entry and alias paths cannot belong to another product identity. The WebUI
+composes valid owners by product id, filters them through authorization and the
+effective View, and resolves the stable entry or migration alias to the first
+available owner route. It emits `govoplan:product-surface-route-resolved` before
+the redirect so migration telemetry can observe alias use without making the
+technical module part of the ordinary label.
+
+The shell projects every authorized, View-visible owner route with a product
+contribution into one stable product navigation item. The product label and
+entry path replace package topology in the primary rail; every contributing
+owner path still marks that item active. `All available tools` is a collapsed,
+permission-derived catalogue built independently of the active View, so a
+focused workflow cannot remove the explicit escape. It may reveal an
+authorized owner route that a View omitted, but never an unauthorized route.
+Navigation visibility preferences do not delete catalogue entries, and the
+original owner routes remain compatible deep links.
+
+The initial promoted destinations are `work.items` at `/work`,

+# Shared navigation layout contract

+Core owns `NavigationPreferenceEditor`, ordered layout resolution, and rail
+rendering. Admin, Tenancy, personal Settings and Views reuse this editor. They
+own loading, authorization, Save, Reload and dirty-state guards; the editor
+emits a draft only after a real edit. A drag onto the same position, keyboard
+pickup/drop without movement, and opening inherited settings do not save or
+create an override.
+
+## Stored document and precedence
+
+The version-1 navigation document retains `order`, `hidden` and `locked` and
+adds optional `separators`, each containing a stable `separator:`-prefixed ID
+and an optional plain-text label of at most 120 characters. Separator IDs and
+module navigation IDs occupy the same `order` list. Separators are presentation
+metadata and never become routes, modules, permissions or authorized surfaces.
+
+Omitting `separators` or using null preserves inherited grouping. An explicit
+empty array removes grouping. Resetting the entire navigation document to null
+removes that scope's override. Existing order-only documents remain readable;
+the editor materializes group markers into a draft only when edited. Unknown
+optional-module order IDs remain stored when currently visible items move, so
+uninstalling or temporarily disabling a module does not destroy its preference.
+
+User order and visibility take precedence over tenant and system preferences.
+System and tenant visibility locks accumulate; lower scopes cannot hide those
+destinations, but may move them. Views may supply a navigation presentation
+inside the already authorized and View-filtered destination set. An explicit
+personal order/layout or visibility preference takes precedence over that
+presentation, not over authorization or the View's surface restrictions.
+Views cannot introduce locks. When multiple modules contribute one product
+entry, it inherits the earliest effective rail position/section and all
+authorized contributors' locks; this does not change operational route
+selection. An owner alias in View layout refers to that composed entry.
+
+## Interaction and reuse
+
+Drag the handle to move either a module or separator before/after another row.
+The handle also supports Space to pick up, arrow keys to move, Enter to drop,
+and Escape to restore the pre-drag draft. Up/down buttons offer the same moves.
+Add module restores an available hidden entry; Remove only hides navigation,
+never uninstalls a module or deletes records. Add separator inserts a new
+optional group label. Remove separator changes grouping only.
+
+Expanded rails display group labels without divider lines. Collapsed rails
+replace these labels with horizontal group dividers; empty groups are not
+rendered. Both modes use the same resolved order.
+The editor receives product-area metadata to show inherited grouping and uses
+container-responsive rows rather than a fixed dialog/page width. Its English
+and German labels load with the editor, not the initial shell bundle.
+Give the ordered list a full-span `GridItem` when a settings page contains
+multiple cards; do not squeeze the entire editor into an otherwise half-empty
+two-column settings grid. Central spacing tokens provide real row padding and
+separation at both wide and narrow sizes, covered by computed-style assertions.
+
+## Verification
+
+Core navigation unit tests and HTTP settings/profile tests cover persistence,
+separator inheritance, explicit flat layouts, reset and locks. Module-capability
+tests cover View aliases, composed destinations and personal precedence. The
+browser conformance suite tests all four editor scopes, pointer/keyboard moves,
+no-op cleanliness, unavailable-module preservation, collapsed dividers and a
+German narrow read-only layout. Use the same shared component for future
+navigation-definition surfaces rather than implementing another sortable list.

 ## Verification
 
+Development startup explicitly prebundles the Excel reader's browser/universal
+entrypoints and the lazy rich-text editor's Tiptap dependencies. These are
+Core-installed vendor dependencies, not eager optional-module imports. This
+avoids first-time Campaign/Template navigation triggering a second dependency
+optimization and page reload. Module descriptors and pages remain lazy, and
+production bundle budgets remain unchanged. The Core interface-pattern check
+verifies this include list and keeps optional GovOPlaN modules excluded.

 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.
+
+The startup shell imports appearance validation/application from the pure
+`appearanceOverrides.ts` runtime. Settings-only color controls, JSON import/export,
+and previews remain in `AppearanceOverridesEditor.tsx` behind the existing lazy
+Settings route. Importing a runtime helper from a module that also owns editor
+components can accidentally pull the entire editor into the startup chunk.
+Public helper exports remain compatible; theme application is still synchronous.
+The versioned default color document and its deep-clone helper live in
+`appearanceOverrideDefaults.ts`, loaded with that editor. Applying saved overrides
+does not load editor defaults or construct a draft. The default values and public
+helper names are unchanged; the theme regression checks independent draft clones
+as well as synchronous validation, application, and reset.
+
+`PasswordField` keeps ordinary input and reveal controls synchronous. Its
+optional `PasswordGeneratorDialog` is imported only after an enabled, editable
+generator is explicitly opened, not for every sign-in/password field. Loading
+and failures use the shared resource boundary; the underlying field remains
+usable. Closing or revoking generation while loading cannot apply a candidate.
+The secure browser RNG, generation policy, public exports, and explicit
+"Use password" confirmation remain unchanged. The isolated browser fixture
+does not import the Core barrel, so it can verify that the generator is not
+requested before opening it, along with cancel/use and focus restoration.
