+# Asset Bank Composition Snapshot Transfer to Details DTOs Agenda
+
+Status: Open
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+The `Bank Composition` section needs a stable details-facing data shape before any component or middleware work can proceed.
+
+Today the underlying information comes from two different sources:
+
+- snapshot state derived from `walkResult`, which should feed `available` files;
+- `asset.json`, which should feed the currently `selected` files for build composition.
+
+This agenda exists to close how those sources should be transferred into Studio-facing DTOs for `Asset Details`.
+
+## Context
+
+Recent packer/runtime work already gives the Studio enough source information to populate a first-wave `Bank Composition` section:
+
+- registered assets have stable identity;
+- the snapshot already contains file inventory derived from `walkResult`;
+- blocking diagnostics already exclude files from being generally available;
+- selection state is persisted in `asset.json` and is expected to move through the newer `artifacts` shape.
+
+The Studio should not bind raw UI code directly to packer internals.
+The section needs a dedicated Studio DTO layer.
+
+## Options
+
+1. Bind the UI directly to snapshot and manifest shapes.
+2. Build one dedicated Studio bank-file DTO for both `available` and `selected` rows.
+3. Build separate DTOs for `available` rows and `selected` rows.
+
+## Tradeoffs
+
+1. Direct binding is fast initially but couples Studio too tightly to packer/runtime structures.
+2. One shared DTO keeps the section simpler and is easier to use across transfer list, meter, and staged draft state.
+3. Separate DTOs may model source differences more explicitly, but they add mapping and coordination overhead early.
+
+## Recommendation
+
+Adopt one dedicated Studio DTO family for bank composition rows and section state.
+
+Baseline direction:
+
+- `walkResult`-derived snapshot rows become `available`;
+- `asset.json` composition state becomes `selected`;
+- both are projected into Studio-owned DTOs before reaching the section UI;
+- the DTO should be generic enough to work for any bank type, even if family-specific fields arrive later.
+- the DTO field set should stay intentionally small and grow only when a concrete UI need appears.
+
+### First-Wave DTO Baseline
+
+The first-wave DTO direction is intentionally pragmatic:
+
+- define one Studio-owned bank-file DTO family for both `available` and `selected` rows;
+- add fields incrementally as real section behavior requires them;
+- do not project blocking files into the UI DTO layer at all;
+- keep selected-file order visual in the UI, but persist it in `asset.json` through an explicit index shape such as `{ file, index }`.
+- start with this minimum first-wave field set:
+  `fileId/path`, `displayName`, `size`, `lastModified`, `fingerprint`, and `metadata`.
+
+## Open Questions
+
+No open questions remain in this agenda wave.
+
+### Resolved In This Agenda Wave
+
+The following points are now closed:
+
+1. The DTO field set should start small and grow only as concrete UI needs appear.
+2. Only non-blocking files become `available` DTOs; blocking files should not be projected into the section DTO layer.
+3. UI ordering is visual, while persisted ordering in `asset.json` should use an explicit index representation such as `{ file, index }`.
+4. The first DTO revision should start with `fileId/path`, `displayName`, `size`, `lastModified`, `fingerprint`, and `metadata`.
+
+## Next Suggested Step
+
+Turn this into a `decision` that closes the first-wave Studio DTO shape for `Bank Composition` details data.

+# Asset Bank Composition Base Components Agenda
+
+Status: Open
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+The `Bank Composition` section depends on two new Studio components:
+
+- `StudioDualListView<T>`
+- `StudioAssetCapacityMeter`
+
+Those components need a first-wave contract and scope before the section shell or middleware can be implemented safely.
+
+## Context
+
+The current direction is already partially fixed:
+
+- `StudioDualListView<T>` should be abstract;
+- the first concrete subclass should be asset-details-specific;
+- right-list ordering must support `move up`, `move down`, and visible indices;
+- `StudioAssetCapacityMeter` should be a vertical, game-like progress bar with color bands and percentage text;
+- both components should stay intentionally dumb and leave family-specific rules to middleware/controller logic.
+
+## Options
+
+1. Build highly generic reusable components from the start.
+2. Build bank-composition-scoped Studio components with narrow first-wave APIs.
+3. Skip dedicated components and build the section directly inside `AssetDetails`.
+
+## Tradeoffs
+
+1. Highly generic components risk overengineering before the first section is proven.
+2. Narrow first-wave components keep momentum and preserve room to generalize later from real usage.
+3. Inline section code would move faster once, but it would bury behavior that already deserves named UI building blocks.
+
+## Recommendation
+
+Build dedicated first-wave components with narrow APIs:
+
+- abstract `StudioDualListView<T>` as the transfer-list base;
+- one asset-details concrete subclass first;
+- `StudioAssetCapacityMeter` as a dumb vertical meter component with color thresholds and percentage display.
+
+Do not force broad reuse rules yet.
+
+### First-Wave Component Baseline
+
+The first-wave component contract should stay intentionally small.
+
+`StudioDualListView<T>` should expose only the hooks needed for the initial bank-composition section:
+
+- row text and/or row graphic projection;
+- current left and right collections;
+- current selection state;
+- move left-to-right;
+- move right-to-left;
+- `moveUp`;
+- `moveDown`;
+- visible index refresh for the right-side list.
+
+The first concrete asset-details subclass should render rows directly.
+Do not introduce a separate row renderer abstraction yet.
+
+`StudioAssetCapacityMeter` should start as a dumb visual component with these baseline inputs:
+
+- `progress` in the `0..1` range;
+- a label, including percentage text when needed;
+- a severity band state;
+- optional hint text.
+
+## Open Questions
+
+No open questions remain in this agenda wave.
+
+### Resolved In This Agenda Wave
+
+The following points are now closed:
+
+1. `StudioDualListView<T>` should expose only a narrow first-wave hook set for row projection, selection, transfers, reordering, and right-list index refresh.
+2. The first concrete asset-details subclass should own row rendering directly.
+3. `StudioAssetCapacityMeter` should start with `progress`, label, severity band state, and optional hint text.
+
+## Next Suggested Step
+
+Turn this into a `decision` that fixes the first-wave component contracts for `StudioDualListView<T>` and `StudioAssetCapacityMeter`.

+# Asset Bank Composition Section Shell Agenda
+
+Status: Open
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+`Bank Composition` needs a section shell inside `Asset Details` before behavior is added.
+
+That shell must align visually and operationally with existing sections, especially `Runtime Contract`, instead of inventing a separate layout and editing model.
+
+## Context
+
+The current baseline is already known:
+
+- `Bank Composition` is a `VBox` section like the others;
+- it is always visible for the current bank-based families;
+- it should follow the same staged-editing model as `Runtime Contract`;
+- the section body should place the dual list on the left and the capacity meter on the right.
+
+This agenda focuses on the static shell and section composition, not the internal behavior.
+
+## Options
+
+1. Add the section only when behavior is ready.
+2. Build the section shell first, with placeholder or disabled behavior.
+3. Hide the section behind an experimental flag.
+
+## Tradeoffs
+
+1. Waiting for full behavior keeps the surface hidden longer and delays visual integration feedback.
+2. A shell-first approach lets the Studio validate section rhythm, spacing, controls, and staged-edit affordances early.
+3. A flag adds operational complexity without much value if the section is already part of the near-term plan.
+
+## Recommendation
+
+Create the `Bank Composition` section shell early, with no real behavior yet.
+
+Baseline expectations:
+
+- section header and actions align with `Runtime Contract`;
+- `change`, `apply`, `reset`, and `cancel` are part of the shell contract;
+- body layout already reserves the dual-list and meter regions;
+- the shell may render with placeholder or disabled internals until middleware arrives.
+
+### First-Wave Shell Baseline
+
+The first-wave shell should mirror `Runtime Contract` as closely as practical at the JavaFX composition level.
+
+That includes:
+
+- the same section rhythm and action placement model;
+- the same staged-edit shell expectations;
+- alignment with the existing `FormSession` pattern instead of inventing a separate section lifecycle.
+
+Before middleware wiring is ready, the body should render in a disabled or read-only state rather than as an empty placeholder.
+
+Outside `change` mode, the section should show the current persisted state as read-only.
+It should not stay visually neutral or look absent when data already exists.
+
+## Open Questions
+
+No open questions remain in this agenda wave.
+
+### Resolved In This Agenda Wave

+

+3. Before middleware is ready, the body should render disabled or read-only internals instead of an empty placeholder.

+# Asset Bank Composition Middleware and Staged Editing Agenda
+
+Status: Open
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+`StudioDualListView<T>` and `StudioAssetCapacityMeter` are intentionally dumb.
+That means `Bank Composition` needs a middleware/controller layer that owns:
+
+- family-specific capacity rules;
+- staged draft state;
+- `change` / `apply` / `reset` / `cancel` orchestration;
+- hard-limit decisions about whether a candidate file can enter the selected list.
+
+Without that layer, component responsibilities will blur quickly.
+
+## Context
+
+The current direction already rejects two extremes:
+
+- no component should hide bank-family rules internally;
+- the first wave should not overgeneralize into a universal bank manager abstraction.
+
+The middleware/controller therefore needs to be explicit, scoped to `Asset Details`, and designed to evolve incrementally.
+
+## Options
+
+1. Put orchestration inside the section control itself.
+2. Create a dedicated bank-composition middleware/controller for the section.
+3. Push family-specific logic down into the transfer list and meter components.
+
+## Tradeoffs
+
+1. Section-local orchestration reduces file count initially, but risks turning `AssetDetails` into a heavy behavior host.
+2. A dedicated middleware/controller keeps the section and components simpler while preserving room for bank-family policies.
+3. Embedding rules into components breaks the current design goal of keeping them dumb and composable.
+
+## Recommendation
+
+Create a dedicated bank-composition middleware/controller for the section.
+
+Baseline expectations:
+
+- own the draft state while editing is active;
+- translate persisted state into editable state on `change`;
+- support `reset` back to the persisted state;
+- support `cancel` by discarding draft changes;
+- keep `apply` stubbed or disabled until persistence is wired;
+- delegate family-specific capacity logic through narrowly scoped policies instead of premature platform-wide abstractions.
+
+### First-Wave Middleware Baseline
+
+The first wave should not introduce a second session model parallel to the one already used by Studio.
+
+The middleware/controller should be built around `StudioFormSession<BankCompositionDraft>` as the common staged-edit core.
+
+Family-specific variation should not come from subclassing `StudioFormSession`.
+It should come from family-specific draft factories and policies that operate on a shared session model.
+
+Baseline direction:
+
+- `StudioFormSession<BankCompositionDraft>` owns `source`, `draft`, `mode`, `isDirty`, `beginEdit`, `reset`, `cancel`, and `apply`;
+- the bank-composition middleware/controller coordinates that form session for the section;
+- each asset family can offer its own draft-construction and bank-composition policy implementation;
+- those policies should decide transfer eligibility, reorder effects, capacity usage, and hard-limit blockers;
+- `apply` may remain stubbed or disabled until persistence is wired, but the session contract should already be complete.
+
+The minimal state published by the middleware/controller should be one section-facing view model carrying:
+
+- shell state such as `isEditing`, `isDirty`, and action availability;
+- left and right list state;
+- capacity-meter state;
+- active blockers and hint messages when relevant.
+
+## Open Questions
+
+No open questions remain in this agenda wave.
+
+### Resolved In This Agenda Wave
+
+The following points are now closed:
+
+1. The middleware/controller should be built around `StudioFormSession<BankCompositionDraft>`, not a parallel staged-edit model.
+2. Family-specific behavior should come from draft factories and policies, not from subclassing `StudioFormSession`.
+3. Family-specific rules should be represented first as small policies offered per asset family.
+4. The middleware/controller should publish one section-facing view model with shell state, list state, meter state, blockers, and hints.
+
+## Next Suggested Step
+
+Turn this into a `decision` that fixes the middleware/controller contract and staged-edit lifecycle for the first wave.

+# Asset Bank Composition WorkspaceBus Interaction Agenda
+
+Status: Open
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+The `Bank Composition` section should use `workspaceBus` for coordination, but the first-wave event contract should stay small and be designed together with the middleware/controller.
+
+This agenda exists to close the first minimal event surface without inventing an oversized bus protocol too early.
+
+## Context
+
+The current baseline is already known:
+
+- events and middleware should evolve together;
+- the first event baseline can stay very small;
+- capacity changes are naturally expressed as percentage deltas or level changes in the `0..1` range;
+- the transfer list and meter should be consumers of orchestrated state, not independent sources of product rules.
+
+## Options
+
+1. Define a broad event taxonomy upfront.
+2. Define only the minimum events needed for the first staged-edit interaction loop.
+3. Avoid `workspaceBus` and wire components directly.
+
+## Tradeoffs
+
+1. A broad taxonomy is easy to regret and hard to prune once code lands.
+2. A minimal contract matches the current incremental direction and keeps future changes cheap.
+3. Direct wiring would fight the current workspace architecture and reduce observability of section state changes.
+
+## Recommendation
+
+Define a minimal first-wave `workspaceBus` contract together with the middleware/controller.
+
+Baseline direction:
+
+- begin with the smallest useful set of section-local events;
+- include capacity increase/decrease semantics in the `0..1` range only as needed;
+- avoid encoding family-specific product rules directly into bus event types.
+
+### First-Wave Event Baseline
+
+The first wave should keep user actions local to the middleware/controller whenever possible.
+
+That means the following actions do not need to become public `workspaceBus` commands in the first implementation:
+
+- `beginEdit`
+- `moveToSelected`
+- `moveToAvailable`
+- `moveUp`
+- `moveDown`
+- `reset`
+- `cancel`
+- `apply`
+
+The middleware/controller should receive those actions locally, recalculate section state, and publish only the state transitions or lifecycle notifications that matter outside the section.
+
+The first public `workspaceBus` notifications should stay minimal:
+
+- `BankCompositionDraftChanged`
+- `BankCompositionCapacityChanged`
+- `BankCompositionApplyRequested`
+- `BankCompositionApplied`
+- `BankCompositionApplyFailed`
+
+Capacity notifications should use absolute progress in the `0..1` range rather than deltas.
+
+A practical first-wave shape for capacity notifications is:
+
+- `progress`
+- `severity`
+- `blocked`
+
+If internal increase/decrease semantics are useful later, they can remain local implementation detail rather than part of the initial public bus contract.
+
+## Open Questions
+
+No open questions remain in this agenda wave.
+
+### Resolved In This Agenda Wave
+
+The following points are now closed:
+
+1. First-wave user actions should stay local to the middleware/controller rather than becoming public bus commands.
+2. The first public `workspaceBus` contract should be notification-oriented.
+3. Capacity notifications should use absolute `0..1` progress rather than deltas.
+4. A minimal first-wave bus surface is enough: draft change, capacity change, apply requested, apply success, and apply failure.
+
+## Next Suggested Step
+
+Turn this into a `decision` that fixes the minimal first-wave `workspaceBus` contract for `Bank Composition`.

+# Asset Bank Composition Persistence and Snapshot Propagation Agenda
+
+Status: Open
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+When the developer clicks `apply`, the selected files for bank composition must be persisted and reflected back into runtime state.
+
+That write path spans Studio and packer concerns:
+
+- staged selected files must be serialized into `asset.json`;
+- the older `inputsByRole` shape should give way to the newer `artifacts` shape;
+- the minimal runtime snapshot must reflect the persisted result after apply.
+
+## Context
+
+The earlier agendas in this sequence assume `apply` may remain disabled or stubbed until persistence is ready.
+This agenda isolates the write-path discussion so the rest of the UI can progress first.
+
+The current direction is already mostly known:
+
+- persistence should happen through packer, not by having Studio write manifest files directly;
+- selected composition should be stored in `asset.json`;
+- runtime state should be refreshed after persistence so `Asset Details` stays coherent.
+
+## Options
+
+1. Let Studio write `asset.json` directly.
+2. Route `apply` through packer services and let packer own manifest persistence plus snapshot refresh.
+3. Persist only to runtime state first and defer manifest persistence.
+
+## Tradeoffs
+
+1. Direct manifest writes from Studio would bypass packer ownership and create duplicate write rules.
+2. A packer-owned write path is cleaner and aligns with existing asset mutation flows.
+3. Runtime-only persistence would create an unstable editing model and almost certainly drift from disk state.
+
+## Recommendation
+
+Route `apply` through packer and persist selected files into `asset.json` using the newer `artifacts` representation.
+
+Baseline expectations:
+
+- `apply` submits the selected ordered files to packer;
+- packer updates `asset.json`;
+- packer propagates the resulting minimal state back into the runtime snapshot;
+- Studio refreshes the section from the updated details/snapshot state instead of trusting stale draft data.
+
+### Persistence Baseline
+
+The first-wave persistence direction is:
+
+- `artifacts` replaces the older `inputsByRole` representation in `asset.json`;
+- the bank-composition selection should therefore persist through `artifacts`, not through a parallel legacy shape;
+- selected file order should remain explicit in persisted data rather than relying on array position alone.
+
+### Apply Refresh and Failure Baseline
+
+After `apply`, the Studio should not trust stale draft state.
+
+The first-wave refresh baseline is:
+
+- packer persists the selected ordered files into `asset.json`;
+- packer refreshes the minimal runtime snapshot state needed by `Asset Details`;
+- the Studio rebinds the section from the refreshed persisted state and returns the section to consistent read-only mode.
+
+The minimum refreshed state should include:
+
+- persisted `selected` rows;
+- the current `available` projection for details;
+- recalculated capacity state;
+- recalculated blockers or eligibility state relevant to the section.
+
+If `apply` fails:
+
+- the draft must not be discarded;
+- the section must remain in editing mode;
+- the middleware/controller should publish `BankCompositionApplyFailed`;
+- the UI should show a local error or hint surface;
+- the user should still be able to retry, reset, or cancel.
+
+## Open Questions
+
+No open questions remain in this agenda wave.
+
+### Resolved In This Agenda Wave
+
+The following points are now closed:
+
+1. `artifacts` should replace the older `inputsByRole` shape rather than coexist with it for bank-composition persistence.
+2. After `apply`, packer should refresh the minimal snapshot state required by `Asset Details` and Studio should rebind from that refreshed persisted state.
+3. If `apply` fails, the draft remains intact, the section stays in editing mode, and the UI surfaces a local failure state while preserving retry, reset, and cancel.
+
+## Next Suggested Step
+
+Turn this into a cross-domain `decision` or a paired `docs/studio` + `docs/packer` decision set that closes the apply write path.

+# Asset Bank Composition Area - Dual List and Capacity Meter Agenda
+
+Status: Open (Umbrella, split into follow-up agendas)
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Problem
+
+The Studio `Assets` details area does not yet expose an explicit authoring surface for bank composition based on internal asset files.
+
+The next planned area is not a simple form row.
+It combines:
+
+- a left-side transfer area with `available files` and `files included in build`;
+- a right-side vertical capacity meter for fixed bank size usage;
+- rule-driven gating where files can no longer be moved into the build set once the bank reaches its fixed size limit.
+
+This looks small in layout terms, but it hides many interaction details:
+
+- which files are shown at all;
+- which files are build-eligible;
+- how diagnostics affect transfer availability;
+- whether order matters;
+- how the meter behaves near or above the limit;
+- and how Studio should explain hard capacity blockers without becoming noisy.
+
+This topic needs a Studio agenda before it becomes a decision or implementation PR.
+
+## Context
+
+Recent packer work now gives the runtime snapshot enough information to support this UI discussion more concretely:
+
+- available files per registered asset;
+- build-candidate files derived from the current walk;
+- file-scoped diagnostics kept segregated for future UI use;
+- measured bank size usage for the current build-candidate set;
+- stable asset identity through `asset_id` for registered assets only.
+
+That means the Studio can now discuss this area against a real backend shape instead of inventing a purely visual placeholder.
+
+Important constraints already known:
+
+1. only registered assets should participate in this internal bank-composition flow;
+2. the snapshot should retain file inventory and build-candidate information, but not raw file bytes;
+3. bank size is fixed on the hardware/runtime side;
+4. when the bank reaches its maximum size, the UI must block adding more files into the build set.
+
+## Current Code Context
+
+The current Studio selected-asset details composition is still centered on:
+
+- summary and actions;
+- runtime contract;
+- diagnostics and preview-related surfaces already present in the details flow.
+
+Relevant code anchors today:
+
+- `prometeu-studio/src/main/java/p/studio/workspaces/assets/details/AssetDetailsControl.java`
+- `prometeu-studio/src/main/java/p/studio/workspaces/assets/details/contract/AssetDetailsContractControl.java`
+- `docs/studio/specs/4. Assets Workspace Specification.md`
+
+There is no existing `DualListView<T>` or dedicated bank-composition control in `prometeu-studio` yet.
+
+That matters because this agenda is not only about layout.
+It is about how a new section inside `Asset Details` should behave and how its internal components should coordinate.
+
+## Recommendation
+
+Create a dedicated `Bank Composition` section inside `Asset Details`, implemented as a `VBox` section just like the other asset-details sections, and explicitly backed by packer runtime data.
+
+Operationally, this section should follow the same staged-editing pattern already used by `Runtime Contract`, including `change`, `apply`, `reset`, and `cancel` actions.
+
+Recommended baseline shape:
+
+1. left side of the section body: a dedicated `StudioDualListView<T>` component with:
+   - left list = available files
+   - right list = files included in build
+2. right side of the section body: a dedicated vertical `StudioAssetCapacityMeter` component showing current measured usage versus fixed bank capacity
+3. hard gating rule:
+   if adding a file would exceed the fixed bank size, the move must be blocked before the item enters the build list
+4. coordination rule:
+   the transfer list and the capacity meter must be built as components for this asset-workspace use case and must be able to exchange typed events through the `workspaceBus`
+
+Why this direction:
+
+- it gives bank composition its own didactic and operational area inside `Asset Details`;
+- it leaves room to discuss many smaller details without destabilizing the rest of selected-asset details;
+- it keeps authoring behavior aligned with the existing `Runtime Contract` section instead of inventing a second editing model inside `Asset Details`;
+- it aligns with the Studio event-driven workspace model already used by the `Assets` workspace.
+
+### Component Direction
+
+The first implementation should not treat these controls as isolated local widgets.
+
+Rules:
+
+- `StudioDualListView<T>` is the component name for the transfer-list surface of this section;
+- `StudioDualListView<T>` should be introduced as an abstract Studio component created for this bank-composition section;
+- `StudioDualListView<T>` should leave concrete behavior to subclasses, with capabilities added incrementally as real bank-composition needs appear;
+- `StudioAssetCapacityMeter` is the component name for the vertical capacity meter of this section;
+- `StudioAssetCapacityMeter` should also be introduced as a Studio component created for this bank-composition section;
+- both components must be able to publish and consume typed events through the `workspaceBus`;
+- the event model must allow coordination not only between the transfer list and the capacity meter, but also with surrounding details/workspace components when selection, eligibility, diagnostics, or staged apply behavior evolves;
+- the first event baseline should stay intentionally small:
+  increase and decrease capacity updates expressed as percentage in the `0..1` range are enough to start;
+- the initial component scope is still bank-composition-specific, even if later refactoring makes them reusable elsewhere.
+
+### Current Baseline Assumptions
+
+The following points are now assumed for the current discussion wave:
+
+1. `StudioDualListView<T>` is abstract, with concrete subclasses supplying bank-specific behavior over time.
+2. `Bank Composition` is always visible for the current asset families, because the currently active bank-based families are `Tile` and `Sound`.
+3. `available files` come directly from the snapshot projection derived from `walkResult`.
+4. only files without blocking diagnostics may appear in `available files`.
+5. file order in the right list affects build output and must be developer-controlled.
+6. the right list therefore needs ordering support and should surface indices as part of the UI.
+7. capacity computation is family-specific and must not be normalized prematurely into one fake universal formula.
+8. the bank-composition section should receive its data as part of the normal asset-details fetch.
+9. `StudioDualListView<T>` and `StudioAssetCapacityMeter` should both remain intentionally dumb; a bank-composition middleware/controller should own family-specific UI rules and hard-limit orchestration.
+10. if the Studio later needs non-bank-based asset handling, that should be introduced via another bank manager/composition manager rather than by overengineering this first wave.
+11. the section should use the same staged interaction model as `Runtime Contract`, with `change`, `apply`, `reset`, and `cancel`.
+
+### Family-Specific Capacity Notes
+
+The current bank-capacity semantics already differ by family:
+
+- `Tile` banks are matrix-based.
+  Example:
+  a `256x256` indexed matrix with tiles configured as `32x32` yields `8x8 = 64` tile slots.
+  If each selected build file contributes one `32x32` tile, the bank can contain at most `64` selected files.
+- `Sound` banks are byte-budget-based.
+  The relevant measure is sample size in bytes, with a fixed bank capacity such as `1 MB`.
+
+That means `StudioAssetCapacityMeter` must be driven by bank-family semantics rather than by one simplistic shared percentage algorithm hidden from the user.
+
+### Meter Behavior Baseline
+
+The current direction for the meter is explicitly game-like:
+
+- a vertical progress-bar style meter that rises as the bank fills;
+- green, orange, and red severity bands instead of one neutral fill;
+- a percentage label below the bar;
+- supporting text or hint copy explaining that banks have fixed capacity and must not be exceeded;
+- hint text should also nudge the developer toward splitting or reorganizing the asset when the bank is too full.
+
+Initial thresholds:
+
+- green below `65%`
+- orange at `>= 65%` or `> 9/16`
+- red at `>= 95%` or `> 14/16`
+
+Hard-limit interaction baseline:
+
+- the UI should disable only moves from left to right when capacity is exhausted or the candidate item would overflow the bank;
+- moving items from right to left must remain possible;
+- ordering actions on the right list must remain possible;
+- the surface should still explain why add is blocked, instead of silently failing.
+
+### Section Workflow Baseline
+
+`Bank Composition` should not auto-persist edits while the developer is moving files around.
+
+The first-wave workflow should mirror `Runtime Contract`:
+
+- `change` enters editable mode;
+- list transfers, ordering, and capacity feedback happen inside the staged draft state;
+- `apply` persists the new composition;
+- `reset` returns the draft to the last persisted state while staying in the editing flow;
+- `cancel` exits editing and discards uncommitted draft changes.
+
+This keeps the mental model of `Asset Details` consistent across sections and avoids mixing immediate-write behavior with staged authoring behavior in the same surface.
+
+### Ordering Baseline
+
+The current first-wave baseline for right-list ordering is:
+
+- `move up`
+- `move down`
+- visible indices on the right/build list
+
+Drag-and-drop may still be attractive later, but it is not yet required to validate the first wave.
+
+## Open Questions
+
+1. What exact first-wave event and controller contract should be defined together for the bank-composition flow, since the `workspaceBus` events and the bank-composition middleware/controller should evolve as one design surface?
+2. What exact explanatory text should the section show for tile-bank exhaustion versus sound-bank exhaustion so the user understands the capacity rule, not just the percentage?
+
+### Resolved In This Agenda Wave
+
+The following points are now closed for the first wave:
+
+1. The UI-facing file-row structure should be a dedicated Studio DTO for any bank type.
+2. The first concrete `StudioDualListView<T>` subclass should be asset-details-specific.
+3. The event contract and middleware/controller shape should be designed together incrementally, without premature generalization.
+4. Detailed wording for family-specific explanatory copy can be deferred until the section contract is otherwise ready.
+
+## Suggested Next Step
+
+Do not implement the area yet.
+
+This umbrella agenda is now intentionally split into focused follow-up agendas aligned to the proposed execution order:
+
+1. snapshot transfer into details DTOs:
+   [`Agenda-01-Asset-Bank-Composition-Snapshot-Transfer-to-Details-DTOs.md`](./Agenda-01-Asset-Bank-Composition-Snapshot-Transfer-to-Details-DTOs.md)
+2. base component construction:
+   [`Agenda-02-Asset-Bank-Composition-Base-Components.md`](./Agenda-02-Asset-Bank-Composition-Base-Components.md)
+3. `Bank Composition` section shell:
+   [`Agenda-03-Asset-Bank-Composition-Section-Shell.md`](./Agenda-03-Asset-Bank-Composition-Section-Shell.md)
+4. bank-composition middleware/controller:
+   [`Agenda-04-Asset-Bank-Composition-Middleware-and-Staged-Editing.md`](./Agenda-04-Asset-Bank-Composition-Middleware-and-Staged-Editing.md)
+5. middleware-driven interaction:
+   [`Agenda-05-Asset-Bank-Composition-WorkspaceBus-Interaction.md`](./Agenda-05-Asset-Bank-Composition-WorkspaceBus-Interaction.md)
+6. persistence:
+   [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](./Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+
+### Proposed Execution Order
+
+The current proposed implementation order is:
+
+1. transfer snapshot state into asset-details DTOs
+2. build the base and concrete UI components
+3. create the `Bank Composition` UI shell with no behavior
+4. introduce the bank-composition middleware/controller and staged DTO flow
+5. wire developer actions through middleware and `workspaceBus`
+6. persist the selected composition back through packer into `asset.json` and the minimal snapshot
+
+This sequence is useful not only for implementation, but also for decision slicing:
+
+- early decisions can close DTO and section-shape questions first;
+- middle decisions can close middleware and event-orchestration questions;
+- the final decision can close persistence into `asset.json` and minimal snapshot propagation.
+
+The next correct step is to work these follow-up agendas in order and derive smaller `decision` records from them instead of trying to close the whole bank-composition architecture in one pass.

+# Bank Composition Base Components Decision
+
+Status: Decided
+Cycle: 2026-03
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Context
+
+The `Bank Composition` section inside `Asset Details` depends on two new Studio components:
+
+- `StudioDualListView<T>`
+- `StudioAssetCapacityMeter`
+
+These components need a first-wave contract before the section shell, middleware, and persistence work can proceed safely.
+
+The DTO projection boundary was already closed in:
+
+- [`Bank Composition Details DTO Projection Decision.md`](./Bank%20Composition%20Details%20DTO%20Projection%20Decision.md)
+
+This decision closes the first-wave component direction discussed in:
+
+- [`Agenda-02-Asset-Bank-Composition-Base-Components.md`](../agendas/Agenda-02-Asset-Bank-Composition-Base-Components.md)
+
+## Decision
+
+Adopt narrow, bank-composition-scoped first-wave components.
+
+The component choices are:
+
+1. `StudioDualListView<T>` remains an abstract Studio component;
+2. the first concrete implementation is asset-details-specific;
+3. `StudioAssetCapacityMeter` is a dumb visual component for vertical capacity display;
+4. neither component should own bank-family product rules.
+
+`StudioDualListView<T>` should expose only the hooks needed by the first `Bank Composition` wave:
+
+- row text and/or row graphic projection;
+- current left and right collections;
+- current selection state;
+- move left-to-right;
+- move right-to-left;
+- `moveUp`;
+- `moveDown`;
+- visible right-list index refresh.
+
+The first asset-details concrete subclass should render rows directly.
+Do not introduce a separate row-renderer abstraction in this first wave.
+
+`StudioAssetCapacityMeter` starts with these baseline inputs:
+
+- `progress` in the `0..1` range;
+- a label, including percentage text when needed;
+- a severity-band state;
+- optional hint text.
+
+## Justification
+
+This keeps component scope small and aligned with the current implementation plan.
+
+The decision avoids two common mistakes:
+
+- overengineering highly generic components before the first section exists;
+- burying section behavior directly inside `Asset Details` with no named component boundary.
+
+Direct row rendering in the first concrete dual-list implementation is the pragmatic choice.
+There is no current evidence that a standalone row-renderer abstraction is needed.
+
+Keeping `StudioAssetCapacityMeter` dumb also protects the future middleware/controller boundary.
+Family-specific rules should not leak into the visual component.
+
+## Invariants and Constraints
+
+The following constraints now apply:
+
+1. `StudioDualListView<T>` must remain abstract in the first wave;
+2. the first concrete `StudioDualListView<T>` implementation belongs to the asset-details flow;
+3. right-list ordering support must include `moveUp`, `moveDown`, and visible indices;
+4. `StudioAssetCapacityMeter` must remain visual and state-driven, not rule-driven;
+5. bank-family capacity logic remains outside both components.
+
+## Explicit Non-Decisions
+
+This decision does not yet define:
+
+- the Java package layout or exact class names for the first concrete asset-details subclass;
+- the `Bank Composition` section shell layout details;
+- the middleware/controller contract;
+- the `workspaceBus` event contract;
+- persistence or apply behavior.
+
+## Propagation Targets
+
+- Studio agendas:
+  [`Agenda-03-Asset-Bank-Composition-Section-Shell.md`](../agendas/Agenda-03-Asset-Bank-Composition-Section-Shell.md)
+  [`Agenda-04-Asset-Bank-Composition-Middleware-and-Staged-Editing.md`](../agendas/Agenda-04-Asset-Bank-Composition-Middleware-and-Staged-Editing.md)

+  [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](../agendas/Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+- Studio specs:
+  [`4. Assets Workspace Specification.md`](../specs/4.%20Assets%20Workspace%20Specification.md)
+- Studio code:
+  future component classes for `StudioDualListView<T>`, the first asset-details concrete implementation, and `StudioAssetCapacityMeter`
+
+## Validation Notes
+
+Examples implied by this decision:
+
+- the right/build list can be reordered through `moveUp` and `moveDown`;
+- the right/build list can display visible indices without requiring middleware-specific rendering logic;
+- the capacity meter can show green, orange, or red state based on inputs from higher-level orchestration without knowing tile or sound rules.

+# Bank Composition Details DTO Projection Decision
+
+Status: Decided
+Cycle: 2026-03
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Context
+
+The `Bank Composition` section inside `Asset Details` needs a stable UI-facing data shape before component, middleware, and persistence work can proceed.
+
+The source information comes from two distinct places:
+
+- runtime snapshot state derived from `walkResult`, which should feed `available` files;
+- persisted `asset.json` composition state, which should feed `selected` files.
+
+The Studio should not bind section UI directly to snapshot internals or raw manifest structures.
+This needs a Studio-owned DTO projection boundary.
+
+This decision closes the DTO direction discussed in:
+
+- [`Agenda-01-Asset-Bank-Composition-Snapshot-Transfer-to-Details-DTOs.md`](../agendas/Agenda-01-Asset-Bank-Composition-Snapshot-Transfer-to-Details-DTOs.md)
+
+## Decision
+
+Adopt one dedicated Studio-owned DTO family for `Bank Composition` details data.
+
+The first-wave projection rules are:
+
+1. snapshot rows derived from `walkResult` become `available` rows in the Studio DTO layer;
+2. persisted composition rows from `asset.json` become `selected` rows in the Studio DTO layer;
+3. both flows must be projected into Studio DTOs before reaching `Asset Details` UI code;
+4. the DTO family must be generic enough to support any bank type, even if family-specific fields are added later;
+5. the DTO field set must stay intentionally small and grow only when concrete UI behavior requires it.
+
+The first DTO revision starts with these fields:
+
+- `fileId/path`
+- `displayName`
+- `size`
+- `lastModified`
+- `fingerprint`
+- `metadata`
+
+Availability and ordering rules are:
+
+1. only non-blocking files become `available` DTO rows;
+2. blocking files must not be projected into the `Bank Composition` DTO layer;
+3. UI ordering is visual in the selected list;
+4. persisted ordering in `asset.json` should use an explicit index representation such as `{ file, index }`.
+
+## Justification
+
+This direction keeps the Studio UI decoupled from packer/runtime internal shapes while still using runtime data as the source of truth.
+
+One shared DTO family is the pragmatic middle ground:
+
+- lighter than separate `available` and `selected` row models;
+- safer than direct binding to snapshot and manifest structures;
+- easier to reuse across section shell, transfer list, meter, and staged editing middleware.
+
+Filtering blocking files before DTO projection also keeps the section contract simpler.
+The UI should receive only rows that are actually eligible to appear as `available`.
+
+Persisted order needs an explicit index in `asset.json` because list order is not a robust persistence contract by itself.
+
+## Implications
+
+The Studio details layer now owns a DTO projection step for `Bank Composition`.
+
+This means:
+
+- component work should consume Studio DTOs, not packer snapshot rows directly;
+- middleware work should operate on DTO-based staged state;
+- persistence work must translate selected DTO order into indexed `asset.json` entries;
+- packer-facing details fetches must expose enough source data to populate the DTO fields above.
+
+## Explicit Non-Decisions
+
+This decision does not yet define:
+
+- the exact Java classes or package layout for the DTOs;
+- the section middleware/controller contract;
+- the `workspaceBus` event contract;
+- the concrete `asset.json` `artifacts` schema beyond the need for explicit indexed order;
+- family-specific explanatory copy for tile versus sound exhaustion.
+
+## Propagation Targets
+
+- Studio agendas:
+  [`Agenda-02-Asset-Bank-Composition-Base-Components.md`](../agendas/Agenda-02-Asset-Bank-Composition-Base-Components.md)
+  [`Agenda-03-Asset-Bank-Composition-Section-Shell.md`](../agendas/Agenda-03-Asset-Bank-Composition-Section-Shell.md)

+  [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](../agendas/Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+- Studio specs:
+  [`4. Assets Workspace Specification.md`](../specs/4.%20Assets%20Workspace%20Specification.md)
+- Studio code:
+  `Asset Details` details fetch, DTO projection layer, and `Bank Composition` section inputs
+- Packer code and docs:
+  details payload shaping and future `asset.json` persistence under the `artifacts` composition path
+
+## Validation Notes
+
+Examples implied by this decision:
+
+- a file with blocking diagnostics does not produce an `available` DTO row at all;
+- a selected file may appear in the UI with visual order `3`, while persistence writes something like `{ file: "...", index: 3 }`;
+- adding new UI needs later should extend the DTO deliberately instead of pulling snapshot internals straight into the section.

+# Bank Composition Middleware and Staged Editing Decision
+
+Status: Decided
+Cycle: 2026-03
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Context
+
+`Bank Composition` needs a control layer above the new UI components because:
+
+- `StudioDualListView<T>` is intentionally dumb;
+- `StudioAssetCapacityMeter` is intentionally dumb;
+- the section must follow the same staged-edit model already used elsewhere in `Asset Details`;
+- capacity and blocker rules differ by asset family.
+
+The current codebase already has a staged-edit primitive in:
+
+- [`StudioFormSession.java`](../../../prometeu-studio/src/main/java/p/studio/controls/forms/StudioFormSession.java)
+
+The earlier `Bank Composition` decisions already fixed:
+
+- DTO projection:
+  [`Bank Composition Details DTO Projection Decision.md`](./Bank%20Composition%20Details%20DTO%20Projection%20Decision.md)
+- base components:
+  [`Bank Composition Base Components Decision.md`](./Bank%20Composition%20Base%20Components%20Decision.md)
+- section shell:
+  [`Bank Composition Section Shell Decision.md`](./Bank%20Composition%20Section%20Shell%20Decision.md)
+
+This decision closes the middleware direction discussed in:
+
+- [`Agenda-04-Asset-Bank-Composition-Middleware-and-Staged-Editing.md`](../agendas/Agenda-04-Asset-Bank-Composition-Middleware-and-Staged-Editing.md)
+
+## Decision
+
+Adopt a dedicated bank-composition middleware/controller built around `StudioFormSession<BankCompositionDraft>`.
+
+The first-wave rules are:
+
+1. `StudioFormSession<BankCompositionDraft>` is the shared staged-edit core for the section;
+2. `Bank Composition` must not introduce a second session model parallel to `StudioFormSession`;
+3. family-specific variation must not come from subclassing `StudioFormSession`;
+4. family-specific variation must come from draft factories and bank-composition policies offered per asset family;
+5. `apply` may remain stubbed or disabled until persistence is wired, but the session contract should already exist.
+
+The middleware/controller owns orchestration around the form session, including:
+
+- translating persisted section state into session source/draft state;
+- beginning edit mode;
+- resetting draft state;
+- canceling edits;
+- applying draft state when persistence is available;
+- evaluating transfer eligibility;
+- evaluating reorder effects;
+- calculating capacity state;
+- calculating hard-limit blockers and hints.
+
+The middleware/controller should publish one section-facing view model that includes:
+
+- shell state such as editing mode, dirty state, and action availability;
+- left and right list state;
+- capacity-meter state;
+- blockers and hint text when relevant.
+
+## Justification
+
+This is the simplest design that matches the actual codebase.
+
+`StudioFormSession` already provides the staged-edit lifecycle the section needs.
+Creating a second middleware-specific session model would duplicate behavior for no gain.
+
+At the same time, subclassing `StudioFormSession` is the wrong variation point.
+The current class is final, and more importantly the lifecycle does not change by asset family.
+What changes by family is bank-composition logic: draft shaping, eligibility, capacity, and blockers.
+
+That makes policies and factories the correct seam.
+
+## Invariants and Constraints
+
+The following constraints now apply:
+
+1. `StudioFormSession<BankCompositionDraft>` is the only staged-edit core for the section in the first wave;
+2. asset-family differences must be modeled outside `StudioFormSession`;
+3. the middleware/controller remains section-specific and should not become a platform-wide bank manager abstraction;
+4. dumb UI components consume derived state and do not own bank rules;
+5. the section-facing output must be consolidated into one view model rather than scattered state channels.
+
+## Explicit Non-Decisions
+
+This decision does not yet define:
+
+- the exact Java class names or package layout for the middleware/controller, policies, or draft factories;
+- the exact shape of `BankCompositionDraft`;
+- the `workspaceBus` event contract;
+- persistence/apply integration with packer;
+- the exact text of family-specific hint and blocker messages.
+
+## Propagation Targets
+
+- Studio agendas:
+  [`Agenda-05-Asset-Bank-Composition-WorkspaceBus-Interaction.md`](../agendas/Agenda-05-Asset-Bank-Composition-WorkspaceBus-Interaction.md)
+  [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](../agendas/Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+- Studio specs:
+  [`4. Assets Workspace Specification.md`](../specs/4.%20Assets%20Workspace%20Specification.md)
+- Studio code:
+  `StudioFormSession` integration, `Bank Composition` section controller/middleware, family-specific draft factories, and family-specific bank-composition policies
+
+## Validation Notes
+
+Examples implied by this decision:
+
+- a tile family and a sound family can share the same `StudioFormSession` lifecycle while using different capacity/blocker policies;
+- the dual list and meter can stay dumb because the middleware/controller supplies already-derived state;
+- when persistence is not wired yet, `beginEdit`, `reset`, and `cancel` still work through the shared form-session model.

+# Bank Composition Persistence and Snapshot Propagation Decision
+
+Status: Decided
+Cycle: 2026-03
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Context
+
+`Bank Composition` reaches across Studio and packer when the developer clicks `apply`.
+
+That write path must:
+
+- persist selected ordered files into `asset.json`;
+- use the newer `artifacts` representation instead of the older `inputsByRole` shape;
+- refresh enough runtime state for `Asset Details` to become consistent again after apply.
+
+The earlier `Bank Composition` decisions already fixed:
+
+- DTO projection:
+  [`Bank Composition Details DTO Projection Decision.md`](./Bank%20Composition%20Details%20DTO%20Projection%20Decision.md)
+- base components:
+  [`Bank Composition Base Components Decision.md`](./Bank%20Composition%20Base%20Components%20Decision.md)
+- section shell:
+  [`Bank Composition Section Shell Decision.md`](./Bank%20Composition%20Section%20Shell%20Decision.md)
+- middleware and staged editing:
+  [`Bank Composition Middleware and Staged Editing Decision.md`](./Bank%20Composition%20Middleware%20and%20Staged%20Editing%20Decision.md)
+- workspace bus interaction:
+  [`Bank Composition WorkspaceBus Interaction Decision.md`](./Bank%20Composition%20WorkspaceBus%20Interaction%20Decision.md)
+
+This decision closes the persistence direction discussed in:
+
+- [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](../agendas/Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+
+## Decision
+
+Route `Bank Composition` apply through packer and persist selection under `asset.json` `artifacts`.
+
+The first-wave rules are:
+
+1. Studio must not write `asset.json` directly;
+2. packer owns persistence of selected bank-composition files;
+3. `artifacts` replaces the older `inputsByRole` representation for this flow;
+4. selected file order must remain explicit in persisted data rather than relying on array position alone;
+5. after a successful apply, Studio must refresh from persisted state rather than trusting stale draft state.
+
+The minimal successful apply flow is:
+
+1. Studio submits the selected ordered files to packer;
+2. packer updates `asset.json` under the `artifacts` representation;
+3. packer refreshes the minimal runtime snapshot state required by `Asset Details`;
+4. Studio rebinds the section from that refreshed persisted state;
+5. the section returns to consistent read-only mode.
+
+The minimum refreshed state after apply must include:
+
+- persisted `selected` rows;
+- the current `available` projection used by `Asset Details`;
+- recalculated capacity state;
+- recalculated blockers or eligibility state relevant to the section.
+
+The failure rules are:
+
+1. if apply fails, the draft must not be discarded;
+2. the section must remain in editing mode;
+3. the middleware/controller should publish `BankCompositionApplyFailed`;
+4. the UI should show a local failure surface;
+5. the user must still be able to retry, reset, or cancel.
+
+## Justification
+
+This keeps write ownership in the correct domain boundary.
+
+Packer already owns asset mutation and runtime refresh logic.
+Letting Studio write manifests directly would duplicate rules and create drift between UI and runtime behavior.
+
+Refreshing from persisted state after success is also necessary.
+Otherwise the section would keep trusting stale draft state and could diverge from what packer actually accepted and wrote.
+
+Preserving the draft on failure is the correct staged-edit behavior.
+The user should not lose work because persistence failed.
+
+## Invariants and Constraints
+
+The following constraints now apply:
+
+1. Studio is not the manifest writer for `Bank Composition`;
+2. `artifacts` is the persistence path for selected bank-composition files;
+3. `inputsByRole` is not the write target for this flow;
+4. successful apply requires snapshot refresh before the section settles back to read-only mode;
+5. failed apply must preserve draft state and editing mode.
+
+## Explicit Non-Decisions
+
+This decision does not yet define:
+
+- the exact final `asset.json` `artifacts` schema beyond explicit ordered file persistence;
+- the concrete packer request/response message names;
+- the exact Java event class payloads for apply success or failure;
+- broader manifest migration strategy outside this `Bank Composition` flow.
+
+## Propagation Targets
+
+- Studio specs:
+  [`4. Assets Workspace Specification.md`](../specs/4.%20Assets%20Workspace%20Specification.md)
+- Studio code:
+  bank-composition apply flow, failure handling, and section refresh behavior
+- Packer docs and code:
+  `asset.json` `artifacts` persistence, write-path integration, and minimal runtime snapshot refresh after apply
+
+## Validation Notes
+
+Examples implied by this decision:
+
+- after a successful apply, the section should reload from the refreshed persisted state instead of keeping the old draft instance;
+- if packer rejects an apply, the selected rows remain in the draft so the user can adjust and retry;
+- selected bank-composition files must be written through `artifacts`, not through `inputsByRole`.

+# Bank Composition Section Shell Decision
+
+Status: Decided
+Cycle: 2026-03
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Context
+
+The `Bank Composition` area needs a visible section shell inside `Asset Details` before behavior and persistence are wired.
+
+The section should not invent a parallel editing model.
+It needs to align with the existing `Asset Details` section rhythm, especially `Runtime Contract`.
+
+The DTO projection boundary and the first-wave component direction were already closed in:
+
+- [`Bank Composition Details DTO Projection Decision.md`](./Bank%20Composition%20Details%20DTO%20Projection%20Decision.md)
+- [`Bank Composition Base Components Decision.md`](./Bank%20Composition%20Base%20Components%20Decision.md)
+
+This decision closes the shell direction discussed in:
+
+- [`Agenda-03-Asset-Bank-Composition-Section-Shell.md`](../agendas/Agenda-03-Asset-Bank-Composition-Section-Shell.md)
+
+## Decision
+
+Create the `Bank Composition` section shell early, before full behavior is implemented.
+
+The shell contract is:
+
+1. `Bank Composition` is a `VBox` section inside `Asset Details`;
+2. the section shell should mirror `Runtime Contract` as closely as practical at the JavaFX composition level;
+3. the section should align with the existing `FormSession` staged-editing pattern;
+4. the section header and action cluster must support `change`, `apply`, `reset`, and `cancel`;
+5. the body layout must reserve the dual-list region on the left and the capacity-meter region on the right;
+6. outside `change` mode, the section should render the current persisted state as read-only;
+7. before middleware wiring exists, the section body should still render disabled or read-only internals rather than an empty placeholder.
+
+## Justification
+
+This keeps the editing model of `Asset Details` coherent.
+
+The developer should not need to learn one staged-edit contract for `Runtime Contract` and another for `Bank Composition`.
+Using the same shell and `FormSession` rhythm lowers implementation risk and reduces UI inconsistency.
+
+Rendering the current persisted state in read-only mode is also the better default.
+It teaches the surface, shows that data exists, and avoids making the section look unfinished or absent whenever editing is not active.
+
+## Invariants and Constraints
+
+The following constraints now apply:
+
+1. `Bank Composition` must exist as a real section shell before middleware behavior is complete;
+2. the shell must follow the same staged-edit interaction model already used by `Runtime Contract`;
+3. `FormSession` is part of the expected section lifecycle;
+4. the section must not collapse into a blank placeholder when behavior is still incomplete;
+5. the shell layout must already reflect the intended dual-list plus capacity-meter structure.
+
+## Explicit Non-Decisions
+
+This decision does not yet define:
+
+- the middleware/controller contract;
+- the `workspaceBus` event contract;
+- the exact disabled/read-only visuals of the early shell;
+- apply persistence behavior;
+- family-specific meter semantics beyond the already agreed general direction.
+
+## Propagation Targets

+  [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](../agendas/Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+- Studio specs:
+  [`4. Assets Workspace Specification.md`](../specs/4.%20Assets%20Workspace%20Specification.md)
+- Studio code:
+  `AssetDetailsControl`, the future `Bank Composition` section control, and any `FormSession` integration needed for staged editing
+
+## Validation Notes
+
+Examples implied by this decision:
+
+- the section can appear in the details view even before middleware logic exists;
+- the shell can show current selection state in read-only mode when the user has not entered `change`;
+- the same section-level action rhythm used by `Runtime Contract` should apply to `Bank Composition`.

+# Bank Composition WorkspaceBus Interaction Decision
+
+Status: Decided
+Cycle: 2026-03
+Domain Owner: `docs/studio`
+Cross-Domain Impact: `docs/packer`
+
+## Context
+
+The `Bank Composition` section should integrate with the Studio workspace event model, but the first-wave `workspaceBus` surface needs to stay intentionally small.
+
+The previous decisions already fixed:
+
+- DTO projection:
+  [`Bank Composition Details DTO Projection Decision.md`](./Bank%20Composition%20Details%20DTO%20Projection%20Decision.md)
+- base components:
+  [`Bank Composition Base Components Decision.md`](./Bank%20Composition%20Base%20Components%20Decision.md)
+- section shell:
+  [`Bank Composition Section Shell Decision.md`](./Bank%20Composition%20Section%20Shell%20Decision.md)
+- middleware and staged editing:
+  [`Bank Composition Middleware and Staged Editing Decision.md`](./Bank%20Composition%20Middleware%20and%20Staged%20Editing%20Decision.md)
+
+This decision closes the first-wave event direction discussed in:
+
+- [`Agenda-05-Asset-Bank-Composition-WorkspaceBus-Interaction.md`](../agendas/Agenda-05-Asset-Bank-Composition-WorkspaceBus-Interaction.md)
+
+## Decision
+
+Adopt a minimal, notification-oriented first-wave `workspaceBus` contract for `Bank Composition`.
+
+The first-wave rules are:
+
+1. user actions should stay local to the bank-composition middleware/controller whenever possible;
+2. the first public `workspaceBus` surface should publish only state transitions or lifecycle notifications that matter outside the section;
+3. the event contract must not encode bank-family product rules directly into event types;
+4. capacity notifications should use absolute progress in the `0..1` range, not deltas.
+
+The first-wave public notification set is:
+
+- `BankCompositionDraftChanged`
+- `BankCompositionCapacityChanged`
+- `BankCompositionApplyRequested`
+- `BankCompositionApplied`
+- `BankCompositionApplyFailed`
+
+The first-wave local-only action set remains inside the middleware/controller:
+
+- `beginEdit`
+- `moveToSelected`
+- `moveToAvailable`
+- `moveUp`
+- `moveDown`
+- `reset`
+- `cancel`
+- `apply`
+
+The first-wave capacity notification should expose at least:
+
+- `progress`
+- `severity`
+- `blocked`
+
+## Justification
+
+This preserves the workspace event architecture without inflating the bus contract too early.
+
+If every section interaction became a public event, the bus would turn into a noisy command surface with little external value.
+The middleware/controller is already the right local place for section commands and recalculation.
+
+Absolute capacity state is also the right public shape.
+It is easier to consume, easier to reason about, and safer for late subscribers than delta-based updates.
+
+## Invariants and Constraints
+
+The following constraints now apply:
+
+1. the first-wave public bus contract is notification-oriented, not command-oriented;
+2. section-local interactions should not become public events unless another subscriber truly needs them;
+3. capacity state must be published as absolute progress;
+4. the bus contract must stay bank-family-neutral at the event-type level.
+
+## Explicit Non-Decisions
+
+This decision does not yet define:
+
+- the exact Java class names or package layout for the new events;
+- the full payload shape of each event beyond the minimum capacity fields already fixed;
+- whether future cross-section coordination will require more bus events;
+- apply persistence semantics with packer.
+
+## Propagation Targets
+
+- Studio agendas:
+  [`Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md`](../agendas/Agenda-06-Asset-Bank-Composition-Persistence-and-Snapshot-Propagation.md)
+- Studio specs:
+  [`4. Assets Workspace Specification.md`](../specs/4.%20Assets%20Workspace%20Specification.md)
+- Studio code:
+  bank-composition middleware/controller, event definitions, and event subscribers in `Asset Details`
+
+## Validation Notes
+
+Examples implied by this decision:
+
+- dragging or reordering inside the dual list does not require a public bus command in the first wave;
+- the capacity meter can react to a published absolute progress state such as `0.72` with `orange` severity and `blocked=false`;
+- apply success or failure can be observed outside the section without exposing every internal section action as a bus event.
