# M1 PR3 — Shell UI & Action Column Design Spec

> **Status:** Approved by ginnoir (brainstorm 2026-06-11).  
> **Branch:** `feat/m1-progression` off `main` (first chunk before automation/prestige/content).  
> **Supersedes (partially):** PR2 story overlay UX in `docs/superpowers/specs/2026-06-11-m1-pr2-playable-loop-design.md` §Story UI.  
> **Parent plan:** `docs/plans/2026-06-11-m1-vertical-slice.md` §PR3.

## Summary

PR3 opens with a **shell refactor** that fixes PR2 UX debt before progression/content land: replace the full-screen story overlay with a three-region layout (nav rail / center panel / right rail), reorganize Play into **behavior-type action columns** with collapsible theme groups, move **all story forks to actions** (Story tab is read-only prose + branching tree), and establish **universal automation** with **shareable text recipes** referencing content action ids.

## What we decided (brainstorm)

| Topic | Decision |
|---|---|
| Timing | **First chunk of PR3** — shell lands at start of `feat/m1-progression`, then T3.1 automation, T3.2 prestige, T3.3 content |
| Story choices | **Actions only** — Story tab has no choice buttons |
| Story tab | **Split pane:** branching tree (larger, ~60%) + long-form prose log (~40%); tree left, log right |
| App shell | **Left nav** (Play, Story, Settings, About) → **center** active panel → **right rail** on Play (resources + inventory + optional event log) |
| Action layout | **Columns by behavior kind**, collapsible **theme/purpose groups** inside each column |
| Column order | **Instant → Loop → Timed → Story → Context** (Timed centered as primary column) |
| Loop vs automation | **Loop** = idle filler while playing (queue empty, nothing timed active). **Automation** = hands-off repeat queue including offline |
| Automation scope | **Universal** — instant, loop, timed, story, context all automatable **after first manual completion** on that action |
| Story automation | Same rule — first time at a fork is conscious; after performing a branch once, that story action can be automated on repeat runs |
| Automation sharing | Recipes **export/import as text**; steps reference stable **content action ids** |
| Event log | **Optional** on Play right rail (collapsible + pref to hide; default visible) |
| Mobile | Column stacking + responsive Story split deferred to PR4 (#10) |
| Approach | **Shell first, typed columns second** within PR3 opener (T3.0) |

## Problem statement (PR2 debt)

1. **Readability** — full-screen story overlay (`bg-black/80`) ghosts underlying UI; hard to read.
2. **Redundant choice paths** — story panel choice buttons and Play actions both visible; unclear authority.
3. **Structural mismatch** — single centered column does not match intended Chronicle-style shell (nav / main / sidebar).
4. **Flat action list** — no distinction between instant, idle loop, timed queue, story decisions, or context switches.

## App shell

```
┌──────────┬─────────────────────────────┬──────────────┐
│ Nav rail │ Center (active panel)       │ Right rail   │
│          │                             │ (Play only)  │
│ ● Play   │  Play → action columns      │ Resources    │
│   Story  │  Story → tree │ prose log   │ Inventory *  │
│   Settings                             │ Event log †  │
│   About  │  Settings / About → content │              │
└──────────┴─────────────────────────────┴──────────────┘

* Inventory placeholder = resource list until item system exists
† Collapsible; pref to hide (default: visible)
```

### Nav rail

- Fixed left column; icons + labels on desktop, icons-only acceptable on narrow widths until PR4.
- **Story unread badge** when new beats arrive (replaces overlay auto-open as primary signal).
- `storyOpenMode` pref remapped: `auto` switches to Story nav or pulses badge instead of opening overlay.

### Center panel

Swaps content by active nav item. No full-screen modal for story.

### Right rail (Play only)

- **Resources** — always visible.
- **Inventory** — resource list placeholder in M1; item grid later.
- **Event log** — collapsible section; `showEventLog` pref (default `true`).

### Removed

- `StoryPanel` full-screen overlay with choice buttons.
- Header Story / Settings buttons replaced by nav rail (Settings may retain drawer or become full center panel — implementer picks cleaner fit).

## Play panel — action columns

### Column order (left → right)

| # | Column | `kind` | Role |
|---|---|---|---|
| 1 | Instant | `instant` | One-shot interactions: buy, sell, trade |
| 2 | Loop | `loop` | Idle upkeep between tasks (rest, passive recovery) |
| 3 | **Timed** | `timed` | Primary gameplay; manual queue + progress bars |
| 4 | Story | `story` | Narrative forks and hard decisions |
| 5 | Context | `context` | Area changes, combat entry, context switches |

Timed column is visually central. Narrow viewports: horizontal scroll with Timed near viewport center.

### Groups within columns

Each action belongs to a **group** (content-defined theme/purpose):

```typescript
group: {
  id: string      // e.g. 'camp', 'tavern', 'buy'
  label: string   // e.g. 'Camp activities', 'Buy'
}
```

- Groups render as **collapsible sections** inside their kind column.
- Examples:
  - **Instant:** Buy, Sell, Trade
  - **Loop:** Camp activities, Travel activities
  - **Timed:** Library, Tavern, Camp (location-themed)
  - **Story:** Arc-specific decision groups
  - **Context:** Region / combat entry groups
- Collapse state stored in `GamePrefs.collapsedActionGroups: Record<string, boolean>`.

### Action card UX (unchanged from PR2 where applicable)

- `storyHint` inline subtitle (default) / hover / info-button per pref.
- `storyTooltip` for mechanics and fork consequences.
- **Story-kind actions** get distinct styling (amber fork badge, border) so diverging paths are obvious in Play.

## Action kinds — engine behavior

### `instant`

- Click → validate afford/unlock → apply costs/yields immediately.
- No queue slot, no duration.

### `timed`

- Current PR1/PR2 behavior: `durationMs`, manual `actionQueue`, progress bar.
- Primary manual play column.

### `loop`

- Runs only when **`activeActionId` is null** and **manual `actionQueue` is empty**.
- Player enables/disables per loop action (toggle); priority order when multiple enabled (content `loopPriority` number, lower first).
- On completion while still idle, immediately repeats same loop action.
- Respects costs; stops if unaffordable.
- **Does not run offline** — idle-present behavior only.

### `story`

- Represents one graph choice. Content field `storyChoiceId` links to `StoryChoice.id`.
- On execute → `applyChoice(state, content, storyChoiceId)` → sibling story actions hide via flags/requirements.
- First visit: only available choices shown; player picks consciously.
- After first manual completion of that action id: eligible for automation queue.

### `context`

- Switches active game context (location, combat scene, etc.).
- M1: stub until opening arc requires it; schema + column chrome ship in T3.0.

## Automation (T3.1 — universal)

### Philosophy

Once the player has **completed an action manually at least once**, they may add it to an **automation queue** that repeats hands-off, **including offline** (within existing offline cap).

Applies to **all kinds** including `story` (after that specific branch was taken once). New/unseen branches remain manual until first completion.

Prestige/knowledge catch-up (T3.2) treats previously cleared routes as already completed for automation unlock purposes — same knowledge model as story fast-forward.

### Queues

| Queue | Purpose |
|---|---|
| `actionQueue` | Manual timed queue (player actively planning) |
| `automationQueue` | Hands-off repeat pipeline |

Automation runner executes when manual queue is idle (exact precedence documented in engine; automation fills gaps like a background worker, distinct from loop-kind idle actions — both may need priority rules: **manual > automation > loop**).

### Automation recipe export/import

Recipes are **shareable text** referencing stable **content action ids** (not display names).

**Canonical multi-line format (v1):**

```text
idlegame-recipe/v1
# name: Early camp grind
gather_supplies
scout_path
rest_briefly
```

- Line 1: magic header with version (`idlegame-recipe/v1`).
- Optional `# name:` comment for human label (ignored by parser if malformed).
- One action id per non-empty, non-comment line.
- Lines must match `/^[a-z][a-z0-9_]*$/` (same id convention as content defs).

**Single-line alias (optional parser support):**

```text
idlegame-recipe/v1:gather_supplies,scout_path,rest_briefly
```

**Compressed variant (long recipes):** same payload JSON + `lz-string` URI encoding as saves (`toRecipeExportString` / `fromRecipeExportString`) — optional in T3.1 if recipes exceed ~20 steps; multi-line text remains the default share format.

**Import validation:**

1. Parse version; reject unknown versions explicitly.
2. Every id must exist in `content.actionsById`.
3. Every id must be **automation-unlocked** for the current player state (`manualCompletionCounts[id] >= threshold`).
4. On failure: user-visible error listing unknown or locked ids — no partial apply unless ginnoir opts in later.

**Export:** serializes current `automationQueue` (or named saved recipe slot if added later) to multi-line text; copy-to-clipboard in Settings or Play automation UI.

### State fields

```typescript
manualCompletionCounts: Record<string, number>  // default {}; gates automation
automationQueue: string[]                       // action ids
enabledLoopActionIds: Record<string, boolean>   // loop toggles
```

Persist in save payload (PR3 adds fields; PR4 may bump `SAVE_VERSION` to 2 with migration).

## Story tab

### Layout

Split pane, resizable on desktop:

```
┌──────────────────────────┬─────────────────────┐
│ Branching tree (~60%)    │ Prose log (~40%)    │
│                          │                     │
│  ○ boot_intro            │  [Full passage text │
│  ├─● route_a             │   for selected or   │
│  │  └─ merchant          │   latest node]      │
│  └─○ route_b (dimmed)    │                     │
│                          │  Scrollable history │
└──────────────────────────┴─────────────────────┘
```

- **Tree (primary surface):** built from story graph + `seenStoryNodeIds` / `storyFlags`. Taken paths emphasized; untaken branches dimmed. Click node → prose log scrolls to that beat. Larger pane because the tree needs manipulation room.
- **Prose log (secondary):** full passage text, not truncated. Choice labels inline: `[You chose: Take the high road]`.
- **No choice buttons.**

### Story map data

- Tree nodes mirror `storyNodesById` edges via choices + triggers.
- Visibility: seen nodes solid; future/locked dimmed or hidden per design.
- M1 T3.0 may ship minimal tree (indented list) before polish; structure must support real graph.

### Unread / navigation

- New story beats → Story nav badge.
- `storyOpenMode: auto` → switch to Story tab or highlight badge (no overlay).

## Content schema changes

```typescript
actionKindSchema = z.enum(['instant', 'loop', 'timed', 'story', 'context'])

actionGroupSchema = z.object({
  id: z.string().min(1),
  label: z.string().min(1),
})

actionDefSchema = z.object({
  id: z.string().min(1),
  name: z.string().min(1),
  kind: actionKindSchema.default('timed'),
  group: actionGroupSchema,
  durationMs: z.number().positive().optional(),  // required for timed + loop
  loopPriority: z.number().int().nonnegative().optional(),
  costs: ...,
  yields: ...,
  unlock: ...,
  storyHint: ...,
  storyTooltip: ...,
  storyChoiceId: z.string().min(1).optional(),  // required when kind === 'story'
  contextId: z.string().min(1).optional(),        // required when kind === 'context'
  automation: z.object({
    unlockAfterManualCompletions: z.number().int().positive().default(1),
  }).optional(),
})
```

**Validation rules:**

- `timed` and `loop` require `durationMs`.
- `instant`, `story`, `context` must not require duration for execution (engine enforces).
- `story` requires valid `storyChoiceId` referencing a choice in the loaded story graph.
- Column placement derived from `kind` (not a separate column field).

### Stub content migration (T3.0)

| Current action | New kind | Group example |
|---|---|---|
| gather_supplies | timed | Camp |
| scout_path | timed | Travel |
| trade_at_camp | timed | Camp |
| fortify_camp | timed | Camp (route A) |
| push_onward | timed | Travel (route B) |
| rest_briefly | loop | Camp activities |
| *(new)* pick_high_road | story | Fork |
| *(new)* follow_river | story | Fork |

Remove parallel choice buttons from story graph UI; fork choices exist only as story-kind actions.

## Architecture

```
src/ui/AppShell.tsx           nav rail + center + right rail layout
src/ui/NavRail.tsx
src/ui/PlayPanel.tsx          action column grid
src/ui/ActionColumn.tsx       one kind column
src/ui/ActionGroup.tsx        collapsible group
src/ui/StoryView.tsx          split tree + prose log (replaces overlay StoryPanel)
src/ui/StoryTree.tsx
src/ui/StoryProseLog.tsx
src/ui/RightRail.tsx          resources, inventory placeholder, event log
src/ui/AutomationBar.tsx      automation queue UI + export/import (T3.1)

src/content/schema.ts         + kind, group, storyChoiceId, contextId, automation
src/engine/game.ts            instant execute, loop idle runner, completion counts
src/engine/automation.ts      automation queue runner, recipe parse/serialize (new)
src/engine/recipe.ts          recipe export/import validation (new)
src/state/viewModel.ts        column/group projection, automation eligibility
src/state/runtime.ts          nav commands, remove overlay; story action → applyChoice
src/state/prefs.ts            + collapsedActionGroups, showEventLog
```

**Boundaries unchanged:** engine pure TS; UI calls runtime only.

## PR3 task order (revised opener)

| Task | Deliverable | Gitea |
|---|---|---|
| **T3.0** | App shell, action columns, story-via-actions, Story tab split, remove overlay | UI gate |
| **T3.1** | Universal automation + automation queue + recipe export/import | #7 |
| **T3.2** | Prestige + knowledge catch-up for automation/story | #8 |
| **T3.3** | Opening arc content on new shell | #11 |

## Testing

### Engine

- Instant action applies costs/yields without queue.
- Loop runs when manual queue idle; stops when timed work queued.
- Priority: manual timed > automation > loop (document exact rules in tests).
- Story action executes `applyChoice`; siblings become unavailable.
- `manualCompletionCounts` gates automation; story actions unlock after first perform.
- Recipe round-trip: export → import → identical queue; reject unknown ids; reject locked ids.

### UI / view model

- Actions projected into correct column and group.
- Group collapse prefs persist.
- Story tab: tree click selects prose; no choice buttons rendered.
- Nav badge on unread story.

### Regression

- Remove/update PR2 overlay tests and story choice button tests.
- Existing queue/tick/story graph tests adapted for action-kind story forks.

## Out of scope (T3.0)

- Polished graph visualization (minimal tree OK).
- Item inventory (resource list placeholder).
- Combat mechanics (context column stub).
- Mobile responsive column stack (PR4 #10).
- Save v2 migration (PR4 #9) — PR3 adds new state fields with defaults in v1 payload until bump.

## PR2 supersession note

PR2 spec locked full-window overlay with in-panel choices. This spec **intentionally replaces** that UX. Engine story graph (`applyChoice`, triggers, flags) remains; only presentation and choice surface move to Play actions + Story read-only tab.
