fix(engine): poll decor-view size to catch fold resizes winit misses
winit's Android backend does not forward content-rect changes that happen while backgrounded (open TODOs in winit 0.30 logged on every resume), so a fold/unfold cycle can leave Bevy rendering and laying out for the previous screen: tableau clipped off the left edge, bottom third empty (#130). Add a continuous decor-view size poller (JNI, every 30 frames) that, on mismatch with the cached Window resolution: writes the real physical size into window.resolution, emits a synthetic WindowResized in logical pixels, and re-arms the safe-area inset poller — covering both the fold-size and inset-staleness cases in one mechanism, without relying on AppLifecycle::WillResume being delivered (it may never be; a new evidence log in rearm_on_resumed settles that question on-device). Closes #130 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

+## Overview
+
+RuFlo V3 is a domain-driven design architecture for multi-agent AI coordination with:
+
+- **15-Agent Swarm Coordination** with hierarchical and mesh topologies
+- **HNSW Vector Search** - 150x-12,500x faster pattern retrieval
+- **SONA Neural Learning** - Self-optimizing with <0.05ms adaptation
+- **Byzantine Fault Tolerance** - Queen-led consensus mechanisms
+- **MCP Server Integration** - Model Context Protocol support
+
+### Current Configuration
+| Setting | Value |
+|---------|-------|
+| Topology | hierarchical-mesh |
+| Max Agents | 15 |
+| Memory Backend | hybrid |
+| HNSW Indexing | Enabled |
+| Neural Learning | Enabled |
+| LearningBridge | Enabled (SONA + ReasoningBank) |
+| Knowledge Graph | Enabled (PageRank + Communities) |
+| Agent Scopes | Enabled (project/local/user) |
+
+---
+
+## Swarm Orchestration
+
+### Topologies
+| Topology | Description | Best For |
+|----------|-------------|----------|
+| `hierarchical` | Queen controls workers directly | Anti-drift, tight control |

+| `ring` | Circular communication | Sequential workflows |
+| `star` | Central coordinator | Simple coordination |
+| `adaptive` | Dynamic based on load | Variable workloads |
+
+### Strategies
+- `balanced` - Even distribution across agents
+- `specialized` - Clear roles, no overlap (anti-drift)
+- `adaptive` - Dynamic task routing
+

+- **HNSW**: 150x-12,500x faster search
+- **EWC++**: Prevents catastrophic forgetting
+- **Flash Attention**: 2.49x-7.47x speedup
+- **Int8 Quantization**: 3.92x memory reduction
+
+### 4-Step Intelligence Pipeline
+1. **RETRIEVE** - HNSW pattern search
+2. **JUDGE** - Success/failure verdicts
+3. **DISTILL** - LoRA learning extraction
+4. **CONSOLIDATE** - EWC++ preservation
+
+### Self-Learning Memory (ADR-049)
+
+| Component | Status | Description |
+|-----------|--------|-------------|
+| **LearningBridge** | ✅ Enabled | Connects insights to SONA/ReasoningBank neural pipeline |
+| **MemoryGraph** | ✅ Enabled | PageRank knowledge graph + community detection |
+| **AgentMemoryScope** | ✅ Enabled | 3-scope agent memory (project/local/user) |
+
+**LearningBridge** - Insights trigger learning trajectories. Confidence evolves: +0.03 on access, -0.005/hour decay. Consolidation runs the JUDGE/DISTILL/CONSOLIDATE pipeline.
+
+**MemoryGraph** - Builds a knowledge graph from entry references. PageRank identifies influential insights. Communities group related knowledge. Graph-aware ranking blends vector + structural scores.
+
+**AgentMemoryScope** - Maps Claude Code 3-scope directories:
+- `project`: `<gitRoot>/.claude/agent-memory/<agent>/`
+- `local`: `<gitRoot>/.claude/agent-memory-local/<agent>/`
+- `user`: `~/.claude/agent-memory/<agent>/`
+
+High-confidence insights (>0.8) can transfer between agents.

 ## 3. Crate Responsibilities

 ### `solitaire_core`
-**Dependencies:** `rand`, `serde`, `chrono` only.
+**Dependencies:** `serde`, `thiserror`, plus the upstream `card_game` and
+`klondike` crates (pinned via the Quaternions registry — never edit upstream).

-The entire game rules engine. No Bevy, no network, no file I/O. Designed to be tested in isolation with `cargo test -p solitaire_core`.
+The game rules layer. No Bevy, no network, no file I/O. Designed to be tested
+in isolation with `cargo test -p solitaire_core`.
+
+Since the card_game migration (2026-06-22, PR #88) the primitive types are
+**upstream**: `Card`, `Deck`, `Suit`, `Rank`, `Session` come from `card_game`;
+`Klondike`, `KlondikePile`, `KlondikeInstruction`, `DrawStockConfig`,
+`Foundation`, `Tableau` come from `klondike`. `solitaire_core` re-exports them
+so downstream crates import from one place and never depend on the upstream
+crates directly.

 Owns:
- All game data models (`Card`, `Suit`, `Rank`, `Pile`, `GameState`)
- Move validation logic
- Scoring engine
- Undo stack
+- `GameState` — a wrapper around the upstream `Session<Klondike>`; the session
+  is the single source of truth for board state and stats
+- `MoveError` and the `Result`-based mutation API
+- `KlondikeConfig` adaptation (`klondike_adapter`) — draw mode, scoring,
+  take-from-foundation
+- `GameMode` (Classic / Zen / Challenge / TimeAttack) and mode-aware scoring
+- Solvability check API (`SolveOutcome`, delegating to `Session::solve`)
 - Win / auto-complete detection
 - Achievement unlock condition evaluation
- Seeded RNG for reproducible deals
+- Seeded deals (same seed ⇒ same layout, via the upstream dealer)
+
+**Rules decisions:**
+- **Stock recycling is unlimited in every draw mode — by design.** Extra
+  passes through the stock are discouraged via the upstream score penalty
+  (applied by the `card_game`/`klondike` session), never blocked with a
+  `MoveError`. This matches mainstream digital solitaire (unlimited redeals
+  in Draw-1) rather than strict tournament rules (3-pass cap). It is load-
+  bearing: the difficulty seed catalog and the winnable-deal solver are
+  verified under unlimited recycling, so introducing a hard pass limit would
+  invalidate both. Locked in by the
+  `draw_one_recycling_is_unlimited_by_design` test in
+  `solitaire_core/src/game_state.rs`. (Decision record: Gitea issue #117.)

 - Daily challenge seed generation

+### `solitaire_wasm`
+**Dependencies:** `solitaire_core`, `serde`, `serde_json`, `chrono`, `wasm-bindgen`, `serde-wasm-bindgen`.

-Thin binary entry point. Registers all Bevy plugins and sets initial window properties.
+WebAssembly bindings for browser-side replay playback. Compiled to `cdylib` via `wasm-pack build`; the output lives in `solitaire_server/web/pkg/` and is served statically by the server.
+
+Intentionally **does not** depend on `solitaire_data` (which pulls in `dirs`, `keyring`, `reqwest`, and other non-WASM crates). Instead it defines a minimal `Replay` mirror with the same serde shape as `solitaire_data::Replay` — the JSON wire format is the compatibility contract.
+
+Owns:
+- `ReplayPlayer` — WASM-exported state machine; steps through a replay's `Vec<ReplayMove>` against a live `GameState`
+- `StateSnapshot` — JS-facing pile snapshot returned by each `step()` call
+- `ReplayMove` / `Replay` mirrors — same serde shape as `solitaire_data` v2 equivalents
+
+Because `ReplayPlayer` uses the same `solitaire_core::GameState` as the desktop client, the two implementations cannot drift: the same seed + move list produces identical pile state at every step on both platforms.
+
+### `solitaire_app`
+**Dependencies:** `bevy`, `solitaire_engine`, `solitaire_data` (+ `jni` on Android).
+
+Thin entry point (desktop binary + Android `cdylib`). Registers all Bevy
+plugins and sets initial window properties. The one crate in the workspace
+allowed `unsafe`: the Android entry point reconstructs the raw JNI handles and
+hands them to the safe `solitaire_data::android_jni` bridge; everything else
+is `forbid(unsafe_code)`.

+(no snapshot stack); the −15 undo penalty is applied by the upstream
+score formula via the session config. Persistence (schema v5) saves
+`saved_moves` as upstream `KlondikeInstruction`s and rebuilds the
+session by replay on load — older files carrying `score`/`undo_count`/
+`recycle_count` keys load fine, the extra fields are ignored.
+
+**Rules decision:** stock recycling is unlimited in every draw mode
+(see the "Rules decisions" note in §3 `solitaire_core`).

-No threads in flight. v0.21.6 cut on 2026-05-08; CHANGELOG accumulates
-the next cycle here.
+## [0.42.0] — 2026-07-06
+
+### Added
+
+- **CI workspace gate.** New `test.yml` workflow runs clippy (deny warnings)
+  and the full test suite on every master push and PR — previously no CI ran
+  tests at all. Caught its own first bug (missing Bevy native deps) on its
+  own PR. (#135)
+- **Schedule ambiguity gate.** A headless test builds the gameplay plugin
+  cluster with Bevy ambiguity detection promoted to error. The initial
+  measurement found 302 system pairs with conflicting data access and no
+  ordering; four burn-down batches (PRs #146–#149) took it to ZERO the same
+  day, and the gate now enforces 0. Keyboard consumption, board painting,
+  and HUD updates all have deterministic order for the first time.
+
+### Changed
+
+- **Browser canvas 36% smaller.** `canvas_bg.wasm` shrank 36.2 MB → 23.2 MB
+  via a size-focused `wasm-release` profile (fat LTO, single codegen unit,
+  opt-level "s"); verified visually identical in production. (#134)
+- **Quaternions API adoption.** Canonical `FOUNDATIONS`/`TABLEAUS` consts in
+  `solitaire_core` replace five scattered enum lists; upstream
+  `Suit::SUITS`/`Rank::RANKS` replace nine hand-rolled arrays, with the
+  texture-atlas indexing re-keyed through tested canonical helpers. Net
+  −177 lines. (#137)
+
+### Fixed
+
+- **Sync push race.** The server's load→merge→store cycle now runs in one
+  transaction; concurrent pushes from two devices can no longer overwrite
+  each other's merge. (#136)
+- **Refresh-token rotation is single-use under concurrency** — rotation
+  gates on the DELETE's row count, so a stolen-then-replayed refresh token
+  loses the race and gets 401. (#136)
+- **Exit sync push actually completes.** Was a detached task killed by
+  process teardown; now a bounded 2-second blocking wait on the app's final
+  frame. (#138)
+- **Server auth hardening.** Login timing no longer reveals whether a
+  username exists; concurrent duplicate registration returns 409 instead of
+  500; avatar uploads are magic-byte checked. (#144, issues #139–#141)
+
+## [0.41.1] — 2026-07-06
+
+### Fixed
+
+- **Oversized pile-marker frames after fold/unfold.** `on_window_resized`
+  resized the marker fill sprite but never its children, so the outline frame
+  and the "A"/"K" watermark kept their spawn-time size after any resize —
+  rendering as oversized grey slabs over empty foundation slots on foldables
+  (found during Galaxy Fold 7 on-device verification of v0.41.0, fixed and
+  re-verified on the same device). Both children are now re-derived from the
+  new layout on every relayout.
+
+### Added
+
+- **Android relayout diagnostics.** Every layout recompute on Android now
+  logs its window dimensions and insets (`layout: resize to WxH …`) — the
+  evidence channel for foldable layout reports (#130).
+
+## [0.41.0] — 2026-07-06
+
+> Consolidates everything shipped since v0.39.0, including the v0.40.0–v0.40.3
+> patch tags (which were cut from this section without renaming it at the time).
+
+### Added
+
+- **Rules decision record: unlimited stock recycling.** Documented in
+  `ARCHITECTURE.md` that unlimited recycling with score penalties (matching
+  mainstream digital solitaire) is intentional, and locked it in with a core
+  test — the difficulty seed catalog and winnable-deal solver are verified
+  under this rule. Resolves the last open finding from the June 500-game
+  audit (issue #117).
+- **Analytics validation runbook.** Documented native Matomo live validation,
+  expected event payloads, and the current web/WASM analytics split.
+- **Android smoke-test runbook.** Updated the Android doc with the current
+  platform status, support matrix, and a physical-device
+  launch/touch/safe-area checklist.
+- **Browser Bevy canvas route and automation support.** Added the `solitaire_web`
+  Bevy WASM build, wired `/play` to the Bevy canvas, added a
+  `window.__FERROUS_DEBUG__` bridge, and introduced Playwright coverage for the
+  web routes and interactive canvas behavior.
+- **Card-game / klondike integration.** Began replacing in-house card and pile
+  internals with upstream `card_game` / `klondike` types, including adapter
+  work, GameMode-aware scoring, upstream instruction serde, `KlondikePile`
+  migration, and documentation for the in-place rewrite phases.
+- **Android keystore integration.** Added Android Keystore JNI wiring via
+  `OnceLock` and improved Android token handling around the app directory.
+
+### Changed
+
+- **Engine plugin modules restructured.** The five oversized plugin files
+  (card, hud, settings, game, input) are now module directories with their
+  test suites in sibling `tests.rs` files — no behaviour change; first phase
+  of the module-split plan (#118).
+- **Core type ownership.** Routed all klondike/card imports through
+  `solitaire_core` and unified local `Suit` / `Rank` with upstream `card_game`
+  types.
+- **Web/WASM build reliability.** Rebuilt WASM packages, cleaned up wasm32 build
+  warnings, added a Binaryen `wasm-opt` pass, pinned upstream git dependencies,
+  and added a CI guard for canvas WASM drift.
+- **Difficulty seed catalog.** Regenerated the difficulty seed list for the
+  latest verified catalog.
+
+### Fixed
+
+- **Safe-area insets now re-polled after app resume.** The inset poller settled
+  permanently once insets first resolved, so inset changes while backgrounded
+  (fold/unfold, rotation, gesture ↔ 3-button nav switch) kept stale layout until
+  the app was killed. Each resume now re-arms a fresh poll window; the cached
+  value is rewritten only when it actually changed, so unchanged resumes still
+  cause no relayout flash. (#116)
+- **Tableau fill on foldables / tall screens.** The tableau fan now spreads from
+  each column's total depth (face-down cards included) and refills on the
+  cold-start deal, every move, and on resize (incl. the Android safe-area-inset
+  resize and fold/unfold), so a near-square viewport such as an unfolded Galaxy
+  Fold no longer leaves the bottom of the screen empty. The fan spread cap was
+  raised so very tall / narrow viewports (e.g. a foldable cover screen) fill
+  further.
+- **Card-move animation jank.** A move now rebuilds a card's child visuals only
+  when its appearance changes (flip / resize / accessibility) instead of
+  despawning and respawning every card's children each `StateChangedEvent`,
+  removing the per-move spike that stuttered the slide animation on
+  high-resolution devices.
+- **Android and modal safe-area layout.** Modal cards now center within the
+  usable area between status and gesture bars, additional modal-spawn guards were
+  added, and Android build scripts now auto-discover SDK/NDK paths and strip
+  native libraries.
+- **Core scoring and undo correctness.** Fixed recycle-count drift, undo score
+  compounding, foundation-to-tableau instruction coverage, and several
+  illegal-move paths discovered during the card-game migration.
+- **Input and rendering issues.** Fixed stock/waste hit testing, accepted waste
+  clicks, delayed first-run onboarding until splash teardown, and kept dragged
+  stacks above all piles.
+- **Draw-Three waste fan hit testing on Android.** The renderer and the click
+  hit-test now share a single `waste_fan_step` / `tableau_col_step` source. They
+  previously diverged under Android's tighter column spacing, shifting the top
+  fanned waste card's hit target onto the card beneath it, so dragging the visible
+  card played the wrong one.
+- **Web runtime stability.** Fixed wasm32 runtime panics, HiDPI canvas surface
+  sizing, WebGL2 shader compatibility, and Firefox boot/render behavior.
+- **Server and data hardening.** Moved bcrypt work to `spawn_blocking`, switched
+  file paths to async I/O where needed, and validated `JWT_SECRET` at startup.
+- **CI and deployment workflow.** Fixed deploy-branch handling, Docker registry
+  secret usage, and related release automation issues.
+
+### Tests
+
+- Ran an Android AVD `Pixel_7` launch smoke for the x86_64 debug APK,
+  including install, NativeActivity launch, safe-area log validation, screenshot
+  render check, onboarding input, and crash-log review.
+- Added direct coverage for Android/touch card corner labels using Unicode suit
+  glyphs.
+- Added schema-v3 persistence round-trip coverage, foundation-to-tableau
+  instruction coverage, expanded WASM unit tests, and Playwright E2E specs for
+  browser routes and game-canvas behavior.
+
+## [0.39.0] — 2026-05-19
+
+### Fixed
+
+- **No-legal-moves detection and banner.** Corrected no-move detection across
+  engine, WASM, and web paths, then surfaced the state to players with an
+  in-game banner instead of silently leaving the board stuck.
+- **Release/deploy automation.** Updated deployment automation so kustomization
+  changes are pushed to the deploy branch instead of the main development
+  branch.
+
+## [0.38.0] — 2026-05-19
+
+### Added
+
+- **Klondike scoring parity.** Added tableau flip bonuses and stock recycle
+  penalties to align scoring with standard Klondike expectations.
+
+### Fixed
+
+- **Core rule enforcement.** Auto-complete now requires an empty waste pile,
+  waste-origin moves reject multi-card transfers, foundation-to-foundation moves
+  are blocked, and undo restores score from the snapshot baseline.
+- **Modal lifecycle guards.** Added missing `ModalScrim` guards to New Game,
+  restore prompt, and no-moves modal spawn sites.
+- **Runtime and server robustness.** Tokio runtime setup degrades gracefully
+  instead of panicking; web replay submission casing/date formatting now matches
+  server expectations; avatar routes are publicly reachable when intended.
+- **Android token and sync merge correctness.** Android tokens are namespaced
+  under the application directory, stored per user, and migrated safely; sync
+  merges preserve draw-one / draw-three win invariants.
+
+## [0.37.0] — 2026-05-19
+
+### Fixed
+
+- **Foundation-to-tableau default.** Made `take_from_foundation` default to true
+  across clients so restored, startup, and web games use the same supported move
+  rules.
+
+## [0.36.12] — 2026-05-19
+
+### Fixed
+
+- **Foundation-to-tableau default.** Set `take_from_foundation` true by default
+  in core so every client inherits the intended house rule without special-case
+  setup.
+
+## [0.36.11] — 2026-05-19
+
+### Fixed
+
+- **Web foundation moves.** Enabled take-from-foundation moves in the web game
+  client.
+
+## [0.36.10] — 2026-05-19
+
+### Added
+
+- **Web resume flow.** Browser games now persist state across page refreshes and
+  can resume through a dialog instead of starting over.
+
+## [0.36.9] — 2026-05-19
+
+### Fixed
+
+- **Settings sync connection flow.** Clicking Connect from Settings now opens the
+  sync-setup modal.
+
+## [0.36.8] — 2026-05-19
+
+### Fixed
+
+- **Restored/startup foundation moves.** Enabled take-from-foundation behavior
+  for restored and startup games, not only newly-created sessions.
+
+## [0.36.7] — 2026-05-19
+
+### Fixed
+
+- **Remaining Android UI issues.** Resolved the final Android UI defects from
+  the review pass, including action-bar/tableau interaction and safe visual
+  spacing.
+
+## [0.36.6] — 2026-05-19
+
+### Fixed
+
+- **Action-bar layout reservation.** Reserved action-bar height in layout so
+  tableau columns do not extend behind bottom controls.
+
+## [0.36.5] — 2026-05-19
+
+### Added
+
+- **Responsive Android action-bar glyphs.** Action-bar glyph font size now scales
+  dynamically on Android to fit available space.
+
+## [0.36.4] — 2026-05-19
+
+### Fixed
+
+- **Classic card labels and HUD overlap.** Corrected classic-card corner-label
+  colors and fixed HUD-band overlap in the Android layout.
+
+## [0.36.3] — 2026-05-19
+
+### Fixed
+
+- **Core, animation, and modal review fixes.** Added the foundation-to-tableau
+  score penalty, hardened solver win validation, guarded zero-duration card
+  animations, aligned initial and dynamic tableau fan spacing, and added missing
+  modal guards for play-by-seed and win-summary paths.
+- **Pause, messages, credentials, and server validation.** Auto-complete respects
+  pause state, standalone plugins register their events, sync passwords are
+  cleared from ECS buffers after auth task spawn, and avatar MIME validation uses
+  exact matches.
+- **Foundation pile rendering.** Raised stack fan z-order above corner labels to
+  prevent bleed-through.
+- **Android release workflow.** Added a manual `workflow_dispatch` trigger to
+  the Android release workflow.
+
+## [0.36.2] — 2026-05-19
+
+### Fixed
+
+- **Comprehensive review fixes.** Addressed 26 issues across core rules, replay
+  controls, modal guards, sync payload timing, server replay casing, time-attack
+  overlays, theme refresh, auth overlays, stats ordering, animations, cursor
+  fallbacks, achievements, server temp-file cleanup, and runtime fallback paths.
+- **Animation and Android label polish.** Cancelled stale win-cascade animations
+  on new game, refreshed Android corner labels on resize, lifted animating cards
+  above lower z-layers, and froze the web timer when auto-complete starts.
+- **Web package and tooling updates.** Rebuilt the WASM package for
+  foundation-to-tableau moves, added ruflo scaffolding, and ignored ruflo runtime
+  state files.
+- **Leaderboard test stability.** Made opt-in / opt-out tests robust under
+  parallel test execution.
+
+## [0.36.1] — 2026-05-18
+
+### Fixed
+
+- **Android HUD gesture conflict.** Stock taps no longer toggle HUD visibility on
+  Android.
+
+## [0.36.0] — 2026-05-18
+
+### Changed
+
+- **Rank model cleanup.** `Rank` now uses explicit discriminants and checked
+  arithmetic, making rank conversions and sequencing more robust.
+- **Instruction generation.** Refined `possible_instructions` alongside the rank
+  arithmetic cleanup.
+- **Session handoff.** Recreated `SESSION_HANDOFF.md` to reflect the `0.35.1`
+  state.
+
+## [0.35.1] — 2026-05-17
+
+### Fixed
+
+- **Leaderboard profile sync.** Fixed three leaderboard/profile issues: wrong
+  toast type for failures, stale display-name label after update, and display
+  name not syncing to the server.
+
+## [0.35.0] — 2026-05-17
+
+### Added
+
+- **Reduced-motion support.** Decorative motion animations are now gated behind
+  `reduce_motion_mode`.
+
+### Changed
+
+- **Performance and runtime cleanup.** Shared a single Tokio runtime across
+  network tasks and gated frame-hot ECS systems on resource changes.
+- **Core/data refactors.** Consolidated the application directory name, added
+  `#[must_use]` to pure helpers, derived `Copy` for `DrawMode`, removed
+  redundant clones, added missing derives to `AchievementContext`, and used
+  saturating move-count arithmetic.
+- **HUD z-layer naming.** Replaced raw HUD popover z-index arithmetic with named
+  layer constants.
+
+### Fixed
+
+- **Android UI and font safety.** Wired FiraMono to stock-empty labels, removed
+  raw physical safe-area pixels from HUD spawns, replaced unsupported chevrons,
+  corrected the Android help hint label, and fixed touch/drop-zone behavior.
+- **Engine modal and panic hardening.** Eliminated several runtime panics, added
+  required transforms to modal scrims, constrained dismiss hit-tests, and guarded
+  home overlay respawns.
+- **Sync/data/server correctness.** Deterministic pile serialization, undo skip
+  handling, byte URL encoding, merge timestamp handling, auth-guarded avatar
+  serving, atomic server writes, and user-id assertions were corrected.
+- **Display-name and token-file boundaries.** Enforced the 32-character display
+  name limit in the sync client and aligned Android keystore temp-file cleanup
+  with the cleanup glob.
+- **WASM error reporting.** `state()` and `step()` now return `Result` so errors
+  surface as JavaScript exceptions.
+- **Sync and leaderboard toasts.** Pull failures and leaderboard opt-in /
+  opt-out failures now produce the intended warning/error feedback.
+
+### Documentation
+
+- Corrected stale focus-ring color documentation.
+
+## [0.34.0] — 2026-05-17
+
+### Fixed
+
+- **Android waste fan and resume layout.** Corrected Android waste-pile fan
+  overlap and a layout desynchronization after resume.
+- **Card-face artwork.** Fixed the wrong bottom-right suit symbol on the jack,
+  queen, and king of spades.
+- **Android corner-label font coverage.** Wired FiraMono into Android corner
+  labels and added `CardImageSet` tests to guard the asset path behavior.
+
+## [0.33.0] — 2026-05-16
+
+### Fixed
+
+- **Face-down cards render as tiny red squares (startup ordering bug)**. The
+  `load_initial_theme` system fell back to `"dark"` when `SettingsResource` was
+  not yet available at `Startup`, which happens on every fresh run before the
+  settings file is read. The dark theme's near-black card back (#151515) renders
+  as fully-off pixels on AMOLED screens, leaving only a 24×32 px red badge
+  visible. Changed the fallback to `"classic"` so startup behaviour matches the
+  `default_theme_id()` set in v0.31.0. Cascade-collapse and top-row legibility
+  issues were visual consequences of the same invisible-card-back problem, not
+  separate layout bugs.
+
+## [0.32.0] — 2026-05-16
+
+### Fixed
+
+- **Stock-count badge overlaps waste pile on Android** (Bug 1). The badge was
+  centred 12 px inward from the stock pile's right edge, but its half-width of
+  17 px pushed it 5 px past the edge. On Android (`H_GAP_DIVISOR = 32`) the
+  inter-pile gap is only ~4 px, so the badge's top-right corner covered the
+  left edge of the adjacent waste card at `Z_STOCK_BADGE = 30` (above the
+  card's Z ≈ 1). Fixed by moving the inset to 20 px so the badge right edge
+  sits 3 px inside the stock card on every device.
+- **Oversized grey header bar** (Bug 2). The top HUD band was a full-width
+  `Node` with an opaque dark-grey `BackgroundColor` sized to `HUD_BAND_HEIGHT`
+  (64 px desktop / 80 px Android). Typical gameplay only shows one tier of
+  score text (~30 px), leaving a large empty grey block. Removed the
+  `BackgroundColor` from the band entity; the green felt now shows through and
+  only the score text and avatar button are visible in the header area.
+
+## [0.31.0] — 2026-05-16
+
+### Fixed
+
+- **Face-down cards rendered as solid red squares on AMOLED phones** (Bug 1).
+  The dark theme's card back (`back.svg`) uses a near-black background
+  (`#151515`) which AMOLED screens render as fully-off pixels, leaving only a
+  tiny `#a54242` red badge visible — exactly what was reported. Fixed by
+  changing the fresh-install default theme from "dark" to "classic" (white
+  background with navy diamond pattern, clearly readable on all display types).
+  Also corrected stale asset paths in `load_card_images` (`cards/backs/back_N`
+  → `cards/backs/classic/back_N`, `cards/faces/XY` → `cards/faces/classic/XY`)
+  so the PNG fallback loads correctly when the embedded theme hasn't arrived yet.
+
+## [0.30.0] — 2026-05-16
+
+### Changed
+
+- **Tableau card spacing tightened.** Face-up card fan reduced from 25% to 18%
+  of card height; face-down from 20% to 14%. Cards on tableau piles sit closer
+  together while still showing enough of each card to read the pile depth.
+
+## [0.29.0] — 2026-05-16
+
+### Fixed
+
+- **APK versionCode hardcoded to 1** (`AndroidManifest.xml`, `build_android_apk.sh`).
+  Every release shipped with `versionCode="1"` / `versionName="1.0"`, so Android
+  silently refused upgrades and Obtainium permanently showed a false update
+  notification. The CI now derives the version code from the release tag
+  (e.g. v0.29.0 → 2900) and stamps it into the APK via `aapt2 link
+  --version-code / --version-name`.
+- **CI kustomize install flaky** (`.gitea/workflows/docker-build.yml`).
+  The `curl | bash install_kustomize.sh` pattern hit GitHub API rate limits
+  on the shared runner IP, causing a `tar: no such file` failure. Replaced
+  with a direct pinned tarball download (kustomize v5.4.3).
+
+## [0.28.0] — 2026-05-14
+
+### Changed
+
+- **Rename: Solitaire Quest → Ferrous Solitaire.** Android package id changed
+  from `com.solitairequest.app` to `com.ferrousapp.solitaire`; existing installs
+  must be uninstalled first (Android treats the new id as a new app).
+  Data directory renamed from `solitaire_quest/` to `ferrous_solitaire/`.
+
+### Fixed
+
+- **BUG-3: Multi-modal stacking** (`hud_plugin.rs`). `handle_menu_button`
+  now checks `scrims.is_empty()` — a `Query<(), With<ModalScrim>>` guard —
+  before calling `spawn_menu_popover`. Tapping ≡ while any modal (Stats,
+  Settings, Profile, Help) is open is now a no-op. Previously Stats + Profile
+  could be open simultaneously.
+- **UX-7: Help text single-line overflow** (`help_plugin.rs`). The HUD menu
+  button description "Menu: Stats, Settings, Profile, Achievements" wrapped to
+  two lines on Android. Shortened to "Open menu (Stats, Settings, Profile...)"
+  which fits on one line. Verified on device.
+- **UX-5b: Home mode glyph corruption** (`home_plugin.rs`). Mode selector icons
+  were using Geometric Shapes block (U+25xx) absent from the bundled FiraMono
+  font — rendered as missing-glyph rectangles on Android. Replaced with card
+  suits (U+2660–2666) which FiraMono covers: ♦ Daily, ♥ Zen, ♠ Challenge.
+- **UX-1: Modal Done button in gesture zone** (`safe_area.rs`). New
+  `apply_safe_area_to_modal_scrims` Bevy system pads every `ModalScrim` bottom
+  by `SafeAreaInsets.bottom / scale_factor`. Modal cards are now centred over
+  the safe area, not the full physical screen. The Settings / Help / Stats Done
+  buttons are reachable on gesture-nav Android devices. Verified on device.

+
+## [0.23.0] — 2026-05-12
+
+Phase 8 sync UI: the self-hosted-server connection flow is now fully
+playable end-to-end. Players can open a Connect modal from Settings,
+enter a server URL + credentials, log in or register, and see the
+sync-status section update live. Token expiry auto-reopens the modal.
+Account deletion ships a two-click destroy flow. Server deployment
+artifacts (Dockerfile + docker-compose) let self-hosters spin up in one
+command.
+
+### Added
+
+- **Sync setup modal — Connect / Disconnect flow** (`432061c`).
+  New `SyncSetupPlugin` (`solitaire_engine/src/sync_setup_plugin.rs`)
+  provides the full server-connection UI. Three tab-stopped text fields
+  (URL, Username, Password) handle keyboard input via `MessageReader<KeyboardInput>`
+  with focus cycling on Tab. "Log In" and "Register" buttons each spawn an
+  async `AsyncComputeTaskPool` task that calls the new
+  `SolitaireServerClient::login()` / `::register()` methods; `poll_auth_task`
+  harvests the result, stores tokens via `store_tokens()`, hot-swaps
+  `SyncProviderResource` to the new server backend, fires
+  `ManualSyncRequestEvent` to pull immediately, and closes the modal.
+  An inline `SyncAuthError` label displays credential errors without a
+  toast. The modal is idempotent (`existing.is_empty()` guard) — safe
+  to open programmatically.
+- **`SyncConfigureRequestEvent`, `SyncLogoutRequestEvent`,
+  `DeleteAccountRequestEvent`** (`432061c`). Three new engine events
+  wire the Settings buttons → plugin handlers. `SyncConfigureRequestEvent`
+  opens the setup modal; `SyncLogoutRequestEvent` disconnects and resets
+  `SyncProviderResource` to `LocalOnlyProvider`; `DeleteAccountRequestEvent`
+  opens the deletion confirmation modal.
+- **Settings sync section — dynamic backend UI** (`432061c`).
+  `sync_row()` in `SettingsPlugin` now takes `backend: &SyncBackend` and
+  renders conditionally: `Local` → "Connect" button; `SolitaireServer` →
+  username label + "Sync Now" + "Disconnect" + "Delete Account". Three new
+  `SettingsButton` discriminants (`ConnectSync` tab 91, `DisconnectSync`
+  tab 92, `DeleteAccount` tab 93) feed into a new `handle_sync_buttons`
+  system extracted from `handle_settings_buttons` to stay within Bevy's
+  16-parameter system limit.
+- **`SolitaireServerClient::login()` and `::register()`** (`432061c`).
+  Both POST to `/api/auth/login` and `/api/auth/register` respectively.
+  Private helper `extract_auth_tokens` parses `{ access_token, refresh_token }`.
+  409 CONFLICT → "username already taken"; 401/403 → "invalid credentials";
+  400 → server message echoed to the player.
+- **Re-auth prompt on token expiry** (`6ce5564`).
+  `poll_pull_result` in `SyncPlugin` now fires `InfoToastEvent("Session
+  expired — please reconnect")` + `SyncConfigureRequestEvent` when the
+  pull task resolves to `SyncError::Auth(_)`. Because the modal is
+  idempotent the re-open is safe to trigger from any system path.
+- **Server deployment artifacts** (`6ce5564`).
+  `solitaire_server/Dockerfile`: multi-stage build (`rust:1.95-slim` →
+  `debian:bookworm-slim`); copies `.sqlx` offline cache so `SQLX_OFFLINE=true`
+  succeeds without a live database at build time; exposes port 8080.
+  `solitaire_server/docker-compose.yml`: single-service compose file;
+  `db-data` volume at `/app/data`; `DATABASE_URL` and `JWT_SECRET` from
+  environment; HTTP health-check via `wget`. `solitaire_server/.env.example`:
+  documents all required variables with generation hint (`openssl rand -hex 32`).
+- **Account deletion flow** (`272d31f`).
+  "Delete Account" in Settings fires `DeleteAccountRequestEvent` →
+  `SyncSetupPlugin::open_delete_confirm_modal` spawns a danger-red
+  confirmation modal with "Cancel" and "Delete Forever" buttons.
+  "Delete Forever" submits an async `PendingDeleteTask` that calls
+  `SyncProvider::delete_account()`; `poll_delete_task` on Ok fires
+  `SyncLogoutRequestEvent` + a success toast; on Err shows an error toast
+  and leaves the modal open. Two-click destroy pattern — no accidental
+  account deletion possible.

+## [0.22.0] — 2026-05-08
+
+Adds difficulty-tier game selection, Android JNI bridges for keystore and
+clipboard, Play-by-Seed dialog, and double-tap auto-move on touch screens.
+Also closes the Prev/Next replay-selector spawn-site item carried since v0.19.0.
+
+### Added
+
+- **Difficulty-tier game mode** (this release).
+  `DifficultyLevel` enum (`Easy / Medium / Hard / Expert / Grandmaster /
+  Random`) added to `solitaire_core::game_state` alongside a new
+  `GameMode::Difficulty(DifficultyLevel)` variant. Five pre-verified seed
+  catalogs (40 seeds each, 200 total) are generated by the new
+  `gen_difficulty_seeds` binary in `solitaire_assetgen`; each catalog
+  contains seeds proven winnable at progressively larger solver budgets
+  (1 K → 200 K moves). `DifficultyPlugin` resolves `StartDifficultyRequestEvent`
+  → catalog seed → `NewGameRequestEvent`; the `Random` tier uses a
+  system-time seed and intentionally bypasses the winnable-only filter.
+  The home overlay gains an expandable `▶ Difficulty` section between the
+  Draw Mode row and the mode-card grid; the last-played tier is persisted
+  in `Settings::last_difficulty` and pre-expands/highlights on re-open.
+  Difficulty wins pool into Classic stats (no separate buckets).
+- **Prev/Next replay selector in the Stats overlay** (`a449f60`).
+  `ReplayPrevButton`, `ReplayNextButton`, `ReplaySelectorCaption`, and
+  `ReplaySelectorDetail` nodes now spawn inside `spawn_stats_screen`
+  as a flex row of two bordered chips flanking a `"Replay N / M"`
+  caption, with a detail line below showing the selected replay's
+  duration + date and an optional `"· Shareable"` badge. Both chips
+  carry `ModalButton(Secondary)` so the existing `repaint_modal_buttons`
+  paint loop gives them hover/press feedback at zero extra cost.
+  `repaint_replay_selector_detail` is wired into the existing
+  `.chain()` alongside `handle_replay_selector_buttons` and
+  `repaint_replay_selector_caption`. The click handler and repaint
+  systems have been registered (and dormant) since v0.19.0; this
+  commit is purely the missing spawn site.
+- **6 new selector unit tests** (`a449f60`). Covers: spawn-site
+  presence (Prev, Next, Caption, Detail all spawn with the screen),
+  caption initial text ("Replay 1 / 1"), detail initial text
+  ("{dur} win on {date}"), Shareable badge when `share_url` is set,
+  empty-history "No replays" caption, and ordinal wrapping.
+  `make_test_replay(time_seconds, share_url)` helper encapsulates
+  `Replay::new(...)` + `chrono::NaiveDate`.
+
+### Fixed
+
+- **`const { assert!() }` for dim-layer z-order test** (`a449f60`).
+  Converted `assert!(Z_REPLAY_DIM < Z_REPLAY_OVERLAY, …)` in
+  `replay_overlay` tests to `const { assert!(…) }` to satisfy
+  `clippy::assertions_on_constants` (constant-fold at compile time
+  rather than a runtime no-op).
+
+### Added (post-cut, same pending release)
+
+- **Double-tap auto-move on touch screens** (`395a322`).
+  `handle_double_tap` fires `MoveRequestEvent` (single card to
+  foundation/tableau, or a whole face-up stack via
+  `best_tableau_destination_for_stack`) when two `TouchPhase::Ended`
+  events on the same card arrive within `DOUBLE_TAP_WINDOW` (0.5 s,
+  slightly wider than the mouse `DOUBLE_CLICK_WINDOW` to account for
+  touch latency). If no legal destination exists, fires
+  `MoveRejectedEvent` (audio + visual rejection feedback).  The system
+  is inserted into the touch drag chain immediately before
+  `touch_end_drag` so `DragState.active_touch_id` and `committed` are
+  still readable; the tap timestamp is tracked in a `Local<HashMap<u32,
+  f32>>` keyed by card ID.
+- **Play-by-Seed dialog** (`0cb1587`).
+  `PlayBySeedPlugin` adds a numeric-input modal that accepts a decimal
+  seed, runs a solver preview in the background (debounced 500 ms via
+  `AsyncComputeTaskPool`), and shows a win/no-win verdict before
+  dealing.  A new `HomeMode::PlayBySeed` card in the home overlay fires
+  `StartPlayBySeedRequestEvent`; the handler in `PlayBySeedPlugin`
+  spawns the dialog.  Digit, Backspace, Enter (confirm), and Escape
+  (cancel) are handled via `ButtonInput<KeyCode>`.  Five unit tests
+  cover spawn, digit append, buffer read, confirm, and cancel paths.
+- **75 new challenge seeds** (`2062bd0`).
+  New `gen_seeds` binary in `solitaire_assetgen` brute-searches seeds
+  in the `0xCAFEBABE…` namespace and filters for hands solvable in
+  ≤250 moves via the core solver.  The 75 confirmed-win seeds are
+  appended to `CHALLENGE_SEEDS` in `solitaire_data::challenge`.
+
+### Fixed (post-cut, same pending release)
+
+- **Gate `handle_fullscreen` to non-Android** (`45436d0`).
+  F11 fullscreen toggle makes no sense on Android (the OS owns window
+  sizing); the fn and its `MonitorSelection`/`WindowMode` imports are
+  now `#[cfg(not(target_os = "android"))]`-gated.  The `add_systems`
+  call is extracted as a separate statement so `#[cfg]` can annotate it
+  (attributes cannot appear mid-chain in Rust).
+- **Android APK launch: export `android_main`** (`202a64d`).
+  `NativeActivity` dlopen-s `libsolitaire_app.so` and calls
+  `android_main` as its entry point. Without the symbol the app
+  crashed immediately with `UnsatisfiedLinkError`. The new function
+  sets `bevy::android::ANDROID_APP` (required by `WinitPlugin`) then
+  delegates to `run()` — equivalent to what `#[bevy_main]` would
+  generate, but usable on an arbitrary entry point name.
+- **Android APK launch: gate `resize_constraints` to non-Android**
+  (`202a64d`). On Android `max_width/max_height` default to `0.0`;
+  Bevy's clamp panicked with `min=800 > max=0`.
+- **Android APK launch: gate `apply_smart_default_window_size` to
+  non-Android** (`202a64d`). The system calls `.clamp(800.0,
+  logical_w)` which panics when the emulator reports zero window
+  dimensions during early Android lifecycle events. The OS controls
+  window size on Android; the system is irrelevant there.
+- **Ignore `.idea/` IDE project files** (`16242e6`). Android Studio
+  created `.idea/` when the project was opened during APK
+  verification; added to `.gitignore` and removed the accidentally-
+  committed files.
+
+### Android verification result
+
+APK boots on `x86_64-linux-android` in a Pixel_7 AVD (Android 14 /
+API 34, SwiftShader Vulkan). App runs for 2+ minutes without crashing.
+Bevy renderer initialises, splash screen loads. This is the first

+## [0.21.8] — 2026-05-08
+
+Patch release for replay-overlay polish. Through-line:
+**notch-label centering + WIN MOVE HC legibility + HC system extension**.
+All three items were "optional polish" flagged in the v0.21.7 handoff;
+all three ship in two commits.
+
+### Added
+
+- **`STATE_SUCCESS_HC` constant** (`c50eaf8`). Brighter lime
+  (`#c8e862`, L≈0.73) in `ui_theme` for use wherever the
+  standard `STATE_SUCCESS` (`#acc267`, L≈0.51) needs extra
+  luminance under HC mode. Sits above the bumped notch ticks
+  (`BORDER_SUBTLE_HC` gray, L≈0.60) so a WIN MOVE marker at
+  this colour is unambiguous.
+- **`HighContrastBackground::with_hc(default, hc)` constructor**
+  (`c50eaf8`). Extends `HighContrastBackground` with an
+  `hc_color: Color` field (default = `BORDER_SUBTLE_HC` via
+  `with_default()`). `update_high_contrast_backgrounds` now
+  reads `marker.hc_color` instead of the hardcoded constant —
+  backwards-compatible; all existing `with_default()` usages
+  continue to bump to gray.
+- **WIN MOVE scrub-bar marker HC bump** (`c50eaf8`). Marker
+  now carries `HighContrastBackground::with_hc(STATE_SUCCESS,
+  STATE_SUCCESS_HC)` so the lime stays lime under HC (brighter
+  lime rather than gray). Pin test locks both the default and
+  HC colour fields on the spawned entity.
+
+### Fixed
+
+- **Scrub-bar notch-label centering** (`b44d277`). Middle
+  three labels ("25%", "50%", "75%") previously had their
+  left edge at the notch; now their text centre coincides
+  with the notch tick. Implemented using the CSS
+  `translateX(-50%)` pattern for Bevy 0.18 UI: a fixed
+  `SCRUB_LABEL_CENTER_WIDTH = 36 px` container with
+  `margin.left = -18 px` is placed at `left: Percent(pct)`,
+  and `Justify::Center` centres the text within it. Endpoint
+  labels ("0%", "100%") keep their flush-left / flush-right
+  anchoring. `with_default()` remains one-argument.

+## [0.21.7] — 2026-05-08
+
+Patch release closing the last major B-2 sub-piece. Through-line:
+**mini-tableau preview dim layer**. The mockup's "Game Peek Band at
+50 % opacity" is now implemented as a full-screen UI scrim that darkens
+the card world during replay so the chrome (banner + move-log panel)
+reads clearly against the scene.
+
+### Added
+
+- **Full-screen tableau dim layer** (`da3e542`). Spawns a
+  `ReplayTableauDimLayer` UI node (100 % × 100 %, 50 % opacity
+  black) at `Z_REPLAY_DIM = Z_REPLAY_OVERLAY − 1 = 54` whenever
+  a replay starts; despawned alongside the banner and move-log
+  panel when the replay ends. Bevy's UI/world compositor means
+  no changes to `card_plugin` are needed — UI nodes always
+  render above world-space sprites regardless of `Transform.z`.
+  The dim layer carries no `Interaction` component (purely
+  visual; pointer events pass through). Adds `Z_REPLAY_DIM`
+  and `TABLEAU_DIM_ALPHA` constants plus two new tests:
+  lifecycle (spawn/despawn mirrors the floating-chip pattern)
+  and z-ordering invariant (`Z_REPLAY_DIM < Z_REPLAY_OVERLAY`
+  pinned). 1275 tests pass / 0 failing.

+All full-screen overlay panels MUST use the `spawn_modal` / `ModalScrim` pattern
+from `solitaire_engine::ui_modal`.
+
+## 14.1 Spawn pattern
+
+```rust
+let scrim = spawn_modal(commands, MyScreenMarker, Z_MODAL_PANEL, |card| {
+    spawn_modal_header(card, "Title", font_res);
+    // ... body nodes ...
+    spawn_modal_actions(card, |actions| {
+        spawn_modal_button(actions, MyCloseButton, "Done", None,
+                           ButtonVariant::Primary, font_res);
+    });
+});
+// Optional: allow clicking the scrim outside the card to dismiss
+commands.entity(scrim).insert(ScrimDismissible);
+```
+
+## 14.2 Guard rule
+
+Before spawning a new modal, check `scrims: Query<(), With<ModalScrim>>`
+and return early if `!scrims.is_empty()` — unless the new modal is
+explicitly replacing the current one (despawn first, then spawn).
+
+## 14.3 Safe area
+
+Every `ModalScrim` automatically receives `padding.top` equal to the logical
+status-bar height and `padding.bottom` equal to the logical gesture-bar height
+via `apply_safe_area_to_modal_scrims` in `SafeAreaInsetsPlugin`. This centres
+the modal card within the usable area between both system bars. Do not manually
+add top or bottom padding to scrim nodes.
+
+## 14.4 Z-ordering
+
+Use `Z_MODAL_PANEL` from `ui_theme` for all modal scrims. Do not use
+raw `z_index` values — they drift and cause ordering bugs.

+
+## 15.1 Build command
+
+```bash
+cargo apk build --package solitaire_app --lib
+adb install -r target/debug/apk/ferrous-solitaire.apk
+```
+
+## 15.2 Coordinate system reminder
+
+Device physical: 1080×2400. Bevy logical: 900×2000. Scale factor: 1.20.
+`adb shell input tap X Y` takes PHYSICAL coordinates.
+To convert from what you see on screen (logical): multiply by 1.20.
+
+## 15.3 Android-specific test checklist
+
+Before shipping any Android build:
+- [ ] Safe area insets arrive and shift HUD correctly (check after 3s)
+- [ ] All modal Done buttons are above the gesture bar
+- [ ] No Geometric Shapes glyphs in UI text
+- [ ] HUD band does not overlap the top status bar
+- [ ] Touch drag-and-drop works on all pile types

-
-This workflow defines a **two-agent system**:
-
-* **Builder Agent** → writes and modifies code
-* **Guardian Agent** → enforces architecture + rejects invalid changes
-
-No code is considered valid unless it passes Guardian validation.
-
---
-
-## 1. Agent Roles
-
-### 1.1 Builder Agent
-
-role: "code_generation"
-
-responsibilities:
-
-* implement features
-* refactor code
-* generate tests (only when justified)
-* follow CLAUDE_SPEC.md
-
-constraints:
-
-* cannot bypass validation
-* must declare intent before writing code
-
-output_contract:
-must_produce:
- change_summary
- files_modified
- reasoning (short)
- code_diff
-
---
-
-### 1.2 Guardian Agent
-
-role: "architecture_enforcement"
-
-responsibilities:
-
-* validate against CLAUDE_SPEC.md
-* detect violations
-* reject or approve changes
-* suggest minimal fixes (not full rewrites)
-
-constraints:
-
-* no feature implementation
-* no large rewrites
-* must be deterministic
-
-output_contract:
-must_produce:
- status: APPROVED | REJECTED
- violations[]
- required_fixes[]
- optional_improvements[]
-
---
-
-## 2. Workflow Pipeline
-
-```text
-User Request
-    ↓
-Builder Agent (proposal + code)
-    ↓
-Guardian Agent (validation)
-    ↓
-IF approved → commit
-IF rejected → feedback → Builder retry
-```
-
---
-
-## 3. Builder Protocol
-
-### Step 1 — Intent Declaration
-
-Builder MUST start with:
-
-```yaml
-intent:
-  feature: "<name>"
-  crates_touched: []
-  systems_affected: []
-  risk_level: low|medium|high
-```
-
---
-
-### Step 2 — Plan
-
-```yaml
-plan:
-  - step: "..."
-  - step: "..."
-```
-
---
-
-### Step 3 — Implementation
-
-* Only modify declared crates
-* Follow ownership rules
-* Use events for cross-system communication
-
---
-
-### Step 4 — Output
-
-```yaml
-change_summary: "..."
-
-files_modified:
-  - path: ...
-    change: "..."
-
-violations_self_check:
-  - none | list
-
-notes: "short reasoning"
-```
-
---
-
-## 4. Guardian Protocol
-
-### Step 1 — Spec Validation
-
-Check against:
-
-* crate boundaries
-* mutation rules
-* event system usage
-* sync guarantees
-* forbidden patterns
-
---
-
-### Step 2 — Invariant Validation
-
-Must verify:
-
-* GameState invariants preserved
-* no new panic paths
-* no blocking calls in engine
-* merge properties unchanged
-
---
-
-### Step 3 — Output Decision
-
-#### APPROVED
-
-```yaml
-status: APPROVED
-
-notes:
-  - "no violations"
-```
-
---
-
-#### REJECTED
-
-```yaml
-status: REJECTED
-
-violations:
-  - id: core_purity_violation
-    file: "solitaire_core/src/..."
-    reason: "uses std::fs"
-
-required_fixes:
-  - "move IO to solitaire_data"
-
-optional_improvements:
-  - "simplify event naming"
-```
-
---
-
-## 5. Enforcement Rules
-
-### Hard Fail (automatic rejection)
-
-* core crate uses IO / Bevy / network
-* GameState mutated outside GameLogicSystem
-* blocking async on main thread
-* duplicate logic across crates
-* merge function altered incorrectly
-
---
-
-### Soft Fail (allowed but flagged)
-
-* unnecessary complexity
-* redundant tests
-* minor architectural drift
-
---
-
-## 6. Iteration Loop
-
-Max attempts per task: **3**
-
-```text
-Attempt 1 → Reject → Fix
-Attempt 2 → Reject → Fix
-Attempt 3 → Final decision
-```
-
-If still failing:
-→ escalate to user
-
---
-
-## 7. Diff Strategy
-
-Builder MUST produce:
-
-* minimal diffs
-* no unrelated refactors
-* no formatting-only changes
-
---
-
-## 8. Test Strategy Integration
-
-Builder rules:
-
-* only add tests if:
-
-  * fixing a bug
-  * protecting complex logic
-  * validating invariants
-
-Guardian rejects:
-
-* redundant tests
-* no-op tests
-
---
-
-## 9. Optional Extensions
-
-### 9.1 Third Agent (Optimizer)
-
-role: performance + cleanup
-
-runs AFTER approval:
-
-* reduce allocations
-* simplify logic
-* improve ECS scheduling
-
---
-
-### 9.2 CI Integration
-
-Pipeline:
-
-```text
-Builder → Guardian → cargo check → clippy → tests
-```
-
-Guardian runs BEFORE compilation to catch structural issues early.
-
---
-
-## 10. Example Interaction
-
-### Builder
-
-```yaml
-intent:
-  feature: "undo stack limit fix"
-  crates_touched: [solitaire_core]
-  risk_level: low
-```
-
-```yaml
-change_summary: "limit undo stack to 64 entries"
-
-files_modified:
-  - solitaire_core/src/game_state.rs
-
-notes: "prevents unbounded memory growth"
-```
-
---
-
-### Guardian
-
-```yaml
-status: APPROVED
-
-notes:
-  - "respects core constraints"
-  - "no invariant violations"
-```
-
---
-
-## 11. Mental Model
-
-* Builder = **creative**
-* Guardian = **strict**
-
-Builder explores
-Guardian enforces
-
-Neither replaces the other.
-
---
-
-## 12. Success Criteria
-
-System is working if:
-
-* architectural violations go to ~0
-* code stays consistent across features
-* refactors become safe
-* complexity grows sub-linearly

-**Last updated:** 2026-05-08 — **v0.21.6 cut and tagged at
-`f63db76`**, working tree clean, all post-tag work pushed to
-origin.
+**Last updated:** 2026-07-06 — v0.41.0 + v0.41.1 released and verified on a
+physical Galaxy Fold 7; issue tracker empty except low-priority #130.

-v0.21.6 is a patch release with through-line:
-**Move Log panel + scrub-UX polish**. v0.21.5 closed out the
-keyboard-accelerator surface (Space / Esc / ← / →) and the
-keybind footer; v0.21.6 builds on that with two parallel
-threads — accessibility + scrub-on-hold polish for the v0.21.5
-surfaces, plus a brand-new Move Log panel anchored to the
-viewport's bottom edge that gives players a 5-row recent-and-
-upcoming move history alongside the existing top-edge banner.
+---

-The Move Log panel is the first replay-overlay surface that
-*isn't* attached to the banner — it lives at a separate screen
-anchor (`bottom: 0`) with its own spawn/despawn lifecycle.
-Establishes the "multi-anchor replay UI" pattern that the
-remaining B-2 sub-piece (mini-tableau preview) will inherit.
+## Current state

-Six commits on the B-2 replay screen-takeover redesign arc land
-here, bringing the post-v0.21.4 total to 12. The remaining B-2
-piece — mini-tableau preview that dims the gameplay tableau
-during replay — is the only major sub-piece still open.
+- **Branch state:** `master` pushed to origin; latest work is the 2026-07-06
+  arc (PRs #121–#131): scripted repo review, five issues filed and fixed,
+  plugin module splits, two releases.
+- **Latest tags:** `v0.41.1` (pile-marker child-resize fix + Android relayout
+  logging) on top of `v0.41.0` (consolidated release for everything since
+  v0.39.0). Both released via tag push → CI signed APK; both verified
+  installed on hardware (`versionCode 4101`).
+- **Working tree:** clean. Local `scripts/*.go` helpers are intentionally
+  gitignored (`.gitignore:43`); `scripts/watch_deploy.sh` is now committed.
+- **Latest verification:** workspace clippy `--all-targets -D warnings`,
+  full test suite, `cargo ndk` clippy for `aarch64-linux-android`, CI release
+  builds green, and an on-device pass on the Fold 7 (fold/unfold layout,
+  safe-area resume, marker fix).
+- **Issue tracker:** #116/#117/#118/#119/#120 all closed 2026-07-06. #130
+  (transient tableau clip after fold) open at low priority — did not
+  reproduce in repeat testing; v0.41.1's relayout logging is the evidence
+  channel if it recurs.

-Full v0.21.6 detail lives in `CHANGELOG.md` § [0.21.6]. This
-file from here on focuses on what's *open* post-cut and how to
-resume.

-## Status at pause
+## 2026-07-06 session summary (v0.40.3 → v0.41.1)

- **HEAD locally:** see `git rev-parse HEAD`. The cut commit is
-  `f63db76`; any post-cut docs edits ride on top of that.
- **HEAD on origin:** matches local. v0.21.6 is fully on origin.
- **Working tree:** clean. No WIP outstanding.
- **`artwork/` directory:** still untracked. Intentional.
- **Build:** `cargo clippy --workspace --all-targets -- -D warnings`
-  clean.
- **Tests:** **1273 passing / 0 failing** across the workspace.
-  Detail in `CHANGELOG.md` § [0.21.6] § Stats.
- **Tags on origin:** `v0.9.0` through `v0.21.6`. v0.21.6 is on
-  `f63db76`; v0.21.5 stays on `a2432df`; v0.21.4 stays on
-  `23ff62c`; v0.21.3 stays on `3d92a91`; v0.21.2 stays on
-  `f23df3b`; v0.21.1 stays on `daa655a`; v0.21.0 stays on
-  `04f9bf9`; v0.20.0 stays on `41a009a`.
+- **Scripted repo review** (cratemap/todoctx/cargoclip/testfail): clippy
+  clean, tests green, error/SQL policies compliant. Five issues filed and
+  all resolved same-day.
+- **#116 safe-area re-poll after resume** (PR #121): `refresh_insets` now
+  gates on the poll counter, settles per cycle, and rewrites insets only on
+  change. Verified on Fold 7 — note both Fold screens report identical
+  insets (top=110 bottom=0), so the re-poll path is a no-op on this device.
+- **#117 Draw-1 recycle** (PR #122): unlimited recycling documented as an
+  intentional rules decision (ARCHITECTURE.md "Rules decisions" +
+  `draw_one_recycling_is_unlimited_by_design` lock-in test). A hard limit
+  would invalidate the difficulty seed catalog and the winnable-deal solver.
+- **#118 module splits** (PRs #124/#125/#127/#128/#129): card, hud,
+  settings, game, and input plugins are now module directories; tests in
+  sibling `tests.rs`, runtime code split along system boundaries
+  (`pub(super)` items, mod.rs glob-imports children). Largest runtime file
+  is now `card_plugin/sync.rs` at 748 lines (was `card_plugin.rs` at 4,129).
+- **v0.41.1 pile-marker fix** (PR #131): marker outline + "A"/"K" watermark
+  children are re-derived from the layout on every resize — previously
+  spawn-time-sized, rendering as oversized grey slabs on empty foundations
+  after fold/unfold. Found via photo evidence, fixed, re-verified on device.
+- **Obtainium note:** reported "no suitable release" for v0.41.0 even though
+  the anonymous releases API, `releases/latest`, and the APK download were
+  all verified fine — client-side issue; sideload via adb was used instead.

+---

-No threads in flight. Working tree clean as of 2026-05-08. New
-work since the cut would land here as commit narratives; for
-the v0.21.6 contents themselves, see `CHANGELOG.md` § [0.21.6].
+## v0.40.0 release (2026-06-25)

-Open next-step menu (Move Log + scrub-UX + keyboard accelerator
-coverage + accessibility are all complete):
-1. **Mini-tableau preview** — the only remaining major B-2
-   sub-piece. Mockup shows a 240 px-tall band at 50 % opacity
-   showing the gameplay tableau peeking through the replay
-   chrome. Implementation needs to add a settings-aware dim
-   overlay or alpha modulation on the tableau cards during
-   replay. Architectural — touches `card_plugin` rendering.
-   Multi-session.
-2. **Move Log auto-scroll** — only relevant if the panel's
-   row count grows beyond the current 5-row fixed window.
-   Currently the prev-2 / active / next-2 layout fits all
-   visible content, so auto-scroll is unneeded. Becomes
-   relevant if a future commit expands the panel's row
-   capacity (e.g. 10-row scrolling list).
-3. **Polish: notch label centering.** Bevy 0.18 lacks a
-   clean `translate-x: -50%` primitive so middle three
-   labels sit slightly right-of-notch. Could use a child
-   Text wrapper with computed left-margin compensation.
-   Tiny commit, requires visual review.
-4. **Polish: WIN MOVE marker HC bump.** Currently uses
-   `STATE_SUCCESS` lime which stays visible under HC, but a
-   contrast bump under HC would make it even more legible
-   alongside the bumped notches. Optional.
+Released via tag push → `.gitea/workflows/android-release.yml` built and signed the
+arm64-v8a release APK (release keystore, `versionCode 4000` / `versionName 0.40.0`,
+29.2 MB) and published it to the Gitea release. Obtainium clients tracking the repo
+pick it up automatically.

-Recommended order: option 1 (mini-tableau preview) is the
-big remaining piece that closes B-2 — best tackled in a
-fresh session because it crosses into `card_plugin`. Options
-3 and 4 are visual polish that benefit from user review.

+
+| PR | Summary |
+|----|---------|
+| #106 | **fix(engine):** Draw-Three waste fan hit-test now shares the renderer's fan step (`card_plugin::waste_fan_step` / `tableau_col_step`). The two had diverged under Android's tighter column spacing (`H_GAP_DIVISOR=32`), shifting the top fanned waste card's click target onto the card beneath it — so dragging the visible top card played the wrong one. Desktop/web were unaffected (the formulas already coincided there). |
+| #105 | **test(engine):** waste-card draggability regression tests (`find_draggable_at` picks the waste top with multiple cards and as a lone card). |
+| #108 | **docs(android):** NDK reference updated `26.3.11579264` → `30.0.14904198`; noted versions are not load-bearing and `build_android_apk.sh` auto-discovers the newest NDK/build-tools. |
+
+Pre-release validation performed locally this session: workspace clippy/test/build
+gates; `aarch64-linux-android` cross-compile + clippy clean (covers the
+`#[cfg(target_os = "android")]` paths that host CI never lints); release manifest
+sanity (`solitaire_app/android/AndroidManifest.xml` has no version fields so CI
+injection works; `lib_name` matches `[lib].name`); and a full signed local APK
+proving the `build_android_apk.sh` packaging pipeline end-to-end.

+## What shipped since v0.39.0
+
+- Browser Bevy canvas route and `window.__FERROUS_DEBUG__` automation bridge landed, with Playwright coverage for `/play`.
+- In-place `card_game` / `klondike` rewrite phases are complete through the latest follow-up:
+  - `5e87358` integrates upstream deps cleanly.
+  - `ae1ecc8` unifies `Suit` / `Rank` with upstream `card_game` types.
+  - `d864d98` routes klondike/card imports through `solitaire_core`.
+  - `9bcf13d`, `56e3b62`, `26f1b00` finish schema-v3 migration coverage, undo/recycle score correctness, and rewrite-plan docs.
+- Android keystore wiring, Android build-script hardening, server auth/runtime hardening, and modal safe-area centering have landed.
+- `CHANGELOG.md` has been caught up from `v0.34.0` through current unreleased work and committed in `7fe6ac6`.
+- Matomo analytics was re-reviewed: `MatomoClient` and `AnalyticsPlugin` are wired through `CoreGamePlugin` on non-wasm targets, and targeted tests now cover opt-in client creation, event encoding, buffer trimming, and analytics mode labels.
+- Native analytics and Android physical-device validation now have runbooks in
+  `docs/analytics-validation.md` and `docs/ANDROID.md`.

+
+### v0.34.0 — Android polish + code-quality sweep (2026-05-16/17)

+### v0.35.0 — Accessibility + sync reliability (2026-05-18)
+
+| Commit | Summary |
+|--------|---------|
+| `eb6c93f` | Silence B0004 by adding Transform to ModalScrim |
+| `6f5cebd` | Fire WarningToastEvent on sync pull failure (was InfoToastEvent) |
+| `87aec5b` | Gate all decorative motion animations under `reduce_motion_mode` |
+
+`reduce_motion_mode` now gates: score pulse, score floater, streak flourish
+(hud_plugin), card-shake on rejected move, foundation completion flourish
+(feedback_anim_plugin). Pattern: gate at the trigger/start system, never at
+the tick system — if the component isn't inserted, the tick path never runs.
+
+### v0.35.1 — Leaderboard bug fixes (2026-05-18)
+
+| Commit | Summary |
+|--------|---------|
+| `8f86d66` | Fix three leaderboard bugs: wrong toast type, stale label, name not synced |
+
+Three bugs fixed:
+
+1. **Wrong toast type on error** — `poll_opt_in_task` / `poll_opt_out_task` error
+   branches now fire `WarningToastEvent` instead of `InfoToastEvent`.
+
+2. **Display name not pushed to server on change** — `Settings` gains
+   `leaderboard_opted_in: bool` (serde-defaulted `false`). Set `true`/`false` when
+   opt-in/out tasks succeed and persisted to `settings.json`. `handle_display_name_confirm`
+   now spawns an `opt_in_leaderboard` task when already opted in — the server's upsert
+   endpoint updates only `display_name` without re-opting-in.
+
+3. **"Public name" label stale after name change** — `LeaderboardPublicNameText` marker
+   component added to the label node. `update_leaderboard_public_name_label` system
+   rewrites the text each frame the panel is open; O(0) cost when panel is closed.
+
+5 new regression tests cover all three bugs.
+

 ## Open punch list

-### Phase Android (build + persistence shipped; runtime gaps remain)
+### 1. Physical-device smoke test — DONE (2026-07-06, Galaxy Fold 7)

- **APK launch verification on AVD / device.** `adb install` then
-  `adb logcat` against the `bevy_test` AVD or an x86_64 device.
-  The build works and persistence is wired, but no end-to-end
-  device run has been logged. Shakes out runtime bugs the build +
-  unit tests can't catch.
- **JNI ClipboardManager bridge.** Replaces the Android stub for
-  the Stats "Copy share link" toast. `arboard` doesn't ship an
-  Android backend; small custom JNI call.
- **Android Keystore for credentials.** `keyring` is target-gated
-  to a stub returning `KeychainUnavailable`; replace with Android
-  Keystore via JNI when sync auth ships on mobile.
- **Google Play Games (gpgs) integration.** Listed as a
-  Phase-Android target since Phase 1; now unblocked by the build
-  target.
- **Cosmetic `cargo apk build --lib` workaround.** Post-sign
-  panic doesn't affect the APK on disk but produces noisy stderr.
-  Either upstream a cargo-apk fix or document `--lib` as
-  canonical in the runbook.
+v0.41.1 installed via adb and the full device checklist passed on hardware:
+fold/unfold layout on both screens (incl. the #116 resume path and the
+pile-marker fix), safe-area inset resolution, Draw-Three waste fan tap
+accuracy (#106), modal centring on both screens, drag-and-drop across all
+pile types, text rendering, kill-and-restore, and the sync token flow.
+Reminder for future gates: AVD is not a substitute — `adb shell input tap`
+doesn't deliver real touch events.

-### Visual-identity follow-ups (post-v0.21.0)
+### 2. Matomo analytics live validation (independent — NOT a release blocker)

-The visual-identity arc is effectively complete: token system,
-chrome migration, splash boot screen, replay-overlay banner,
-card-face artwork (both rendering paths), and the `ACCENT_PRIMARY`
-palette refresh all shipped in v0.20.0 + v0.21.0. What stays open:
+Separate, ongoing task unrelated to the Android release. `Settings` has
+`analytics_enabled`, `matomo_url`, and `matomo_site_id`; the engine consumes them via
+`AnalyticsPlugin` on non-wasm targets. Remaining work is live validation against the
+deployed Matomo instance. Use `docs/analytics-validation.md` for the native
+validation checklist and the current web/WASM decision notes.

- **Replay-overlay screen-takeover redesign.** The full mockup
-  (`docs/ui-mockups/replay-overlay-mobile.html`) calls for a
-  mini-tableau preview, playback controls, move-log scroll, and
-  a WIN MOVE marker on the scrub bar. Banner-local pieces all
-  shipped in v0.21.0 (`c84d9f4` + `6204db8` + `54005d5` +
-  `e080b49`); the floating MOVE chip above the focused card
-  shipped in v0.21.2 (`2fb2d63`). The WIN MOVE scrub-bar marker
-  shipped post-v0.21.3 in `ab857bb` (data field) + `52befa6`
-  (UI). Playback controls (pause / resume / step + Space
-  accelerator) shipped post-v0.21.3 in `fbe48ac`. v0.21.5
-  bundled six more commits under "replay-overlay scrubbing
-  affordances + accessibility" (scrub notches + labels +
-  keybind footer + ESC and ← / → accelerators + HC border).
-  v0.21.6 bundled six more under "Move Log panel + scrub-UX
-  polish" — bottom-edge Move Log panel with prev/active/next
-  rows + active highlight, HC-mode coverage for the scrub
-  track + notches, continuous scrub on key-held arrows. Banner
-  height grew 60 → 76 → 92 px across two layout-changing
-  commits in v0.21.5; Move Log panel grew 56 → 84 → 112 px
-  across the v0.21.6 move-log commits. Per-commit detail in
-  `CHANGELOG.md` § [0.21.5] and § [0.21.6]. The only major
-  B-2 piece left is the mini-tableau preview — the mockup's
-  "Game Peek Band" at 50 % opacity. Architectural; touches
-  `card_plugin` rendering.
-  Multi-session.
- *Floating `MOVE N/M` chip above the focused card during
-  playback — closed 2026-05-08 by `2fb2d63`.* World-space
-  `Text2d` entity sibling to the banner overlay; uses the same
-  `LayoutResource` pile coordinates so it survives window
-  resizes without UI/camera math.
- *Toast Warning variant wiring — closed 2026-05-08 by `279e23d`.*
-  Daily-challenge-expiry toast fires once per `daily.date` when
-  within 30 min of UTC midnight reset and today is incomplete.
-  `ToastVariant` is now fully load-bearing (every variant has at
-  least one real driver). Future Warning drivers can either reuse
-  the generic `WarningToastEvent(String)` carrier or add their
-  own domain message + `animation_plugin` handler.
- *Toast Error variant wiring — closed 2026-05-08 by `68d50b5`.*
-  `MoveRejectedEvent` now fires a 2-second pink-bordered
-  "Invalid move" toast as the third leg of the
-  audio + visual + text rejection-feedback stool.
- *High-contrast accessibility mode — closed 2026-05-08 by
-  `c5787c6` + `07e0357` (engine + UI) + v0.21.2's HC chrome
-  rollout (`c9af1ea` + `d87761d` + `ec804d5`) + post-cut
-  dynamic-paint rollout (`c153363`).* Card text rendering plus
-  8 static-border chrome surfaces (modal scaffold, tooltip,
-  onboarding key chips, help panel key chips, stats panel
-  cells, home Level/XP/Score row, home mode buttons, home
-  mode-hotkey chips, 4 settings panel surfaces) all boost
-  borders to `BORDER_SUBTLE_HC` under HC via the
-  `HighContrastBorder` marker. The previously-carved-out
-  dynamic-paint sites are now also covered: HUD action buttons
-  and modal buttons take the same marker (their paint cycles
-  only mutate `BackgroundColor`, so no race); the radial menu
-  rim folds HC into its per-frame spawn via
-  `radial_rim_outline` so the focused rim boosts to
-  `BORDER_SUBTLE_HC` under HC (preserving focused-vs-resting
-  hierarchy that naive marker substitution would invert).
- *Reduced-motion mode — closed 2026-05-08 by `c5787c6` +
-  v0.21.2's `ed152e2`.* `effective_slide_secs` forces 0 on
-  card animations; `pulse_splash_cursor` skips the per-frame
-  pulse multiplier; `spawn_splash` skips the scanline overlay
-  entirely. Future scope: gate any future card-lift z-bump
-  animation, warning-chip pulse (when one materialises).
+---

-### Carried forward from v0.19.0
+## Architectural notes for next session

- *App icon round — closed 2026-05-08 by `3eb3a26` + `716a025`.*
-  Runtime `Window::icon` wired (Linux/macOS/Windows); 9-size
-  PNG hierarchy at `assets/icon/icon_<size>.png` covers Linux
-  hicolor + downstream `.icns`/`.ico` packaging needs. The
-  `.ico` and `.icns` bundle-format files themselves are *not*
-  generated — both would need new crate deps (`ico` and
-  `icns` respectively) and only matter at app-bundle time
-  (cargo-bundle / packaging), not at `cargo run`. Open if the
-  project later ships as a packaged macOS / Windows app.
+- **Plugin submodule pattern (2026-07-06 splits):** big plugins are module
+  directories: `mod.rs` holds types/markers/plugin-build and glob-imports the
+  children (`use input::*;`); children hold `pub(super)` systems and start
+  with `use super::*;` plus their own external imports. Tests (`tests.rs`)
+  may need explicit imports for names no longer used by `mod.rs` itself.

-### Other small candidates
+- **Marker child-resize rule:** anything spawned as a *child* of a
+  layout-sized entity (outline frames, watermark text) must be re-derived in
+  `on_window_resized` too — resizing only the parent sprite leaves children
+  at spawn-time size (the v0.41.1 foldable bug).

- **Prev/Next selector chips spawn site.** v0.19.0's `9b065e5`
-  noted Prev/Next markers exist in `stats_plugin` but no spawn
-  site renders them today — the Shareable badge therefore lands
-  on the single-replay caption. If/when Prev/Next is plumbed,
-  the badge will need to follow.
- **Toast queue / immediate unification.** The two toast paths
-  (`spawn_queued_toast` for `InfoToastEvent` queue; `spawn_toast`
-  for fire-and-forget) now share visual treatment but remain
-  separate functions because they serve different temporal
-  needs (sequential vs. parallel). If overlap becomes a UX
-  issue, merge into one queue with priority lanes.
+- **Fold 7 quirks:** both screens report identical safe-area insets
+  (top=110, bottom=0), so inset-driven relayout never fires on fold; layout
+  correctness across folds rides entirely on `WindowResized`. winit 0.30
+  logs `TODO: find a way to notify application of content rect change` on
+  resume — see #130 if a stale-width layout ever reproduces; v0.41.1 logs
+  every Android relayout (`layout: resize to WxH`) for exactly this.

-### Process notes
+- **Reduce-motion pattern:** always gate in the `start_*` / `detect_*` system
+  (the trigger), not the `tick_*` system. If the component is never inserted, the
+  tick path never runs. See `hud_plugin.rs::detect_score_change` and
+  `feedback_anim_plugin.rs::start_shake_anim` for the canonical pattern.

- **The desktop-adaptation spec is the canonical reference for
-  geometry decisions** when porting any future plugin. Read
-  `docs/ui-mockups/desktop-adaptation.md` first; apply the
-  universal rules to every surface; consult the per-screen
-  table for the priority surfaces. The 9 missing-plugin screens
-  (splash now ported; eight remaining) inherit the universal
-  rules without dedicated guidance.
- **Stitch `generate_variants` is unreliable for layout-only
-  adaptation prompts** as of 2026-05-07. The first call timed
-  out and no variant ever landed in `list_screens`. If a future
-  session wants visual desktop mockups, prefer
-  `generate_screen_from_text` with a fresh narrow prompt per
-  screen rather than `generate_variants` against existing
-  mobile screens.
- **Token-port pattern.** v0.20.0's chrome-migration commits
-  set a reusable shape for "centralised design system applied
-  across N plugins":
-  1. Constants module (`ui_theme.rs`) is the source of truth.
-  2. Const sites that can't call `Alpha::with_alpha` (not yet
-     `const` on stable) use a literal RGB matching the token,
-     with a unit test pinning the RGB to the token (e.g.
-     `MARKER_VALID`, `HINT_PILE_HIGHLIGHT_COLOUR`,
-     `RIGHT_CLICK_HIGHLIGHT_COLOUR`).
-  3. Cross-plugin duplication (e.g. `MARKER_DEFAULT` ↔
-     `PILE_MARKER_DEFAULT_COLOUR`) collapses to a single
-     promoted const re-exported from one plugin and imported
-     by the other — replaces "kept in sync" doc comments with a
-     compile-time invariant.
-  4. Domain colours (suit pips, card faces, lerp helpers) stay
-     as literals with a comment naming the rationale; only UI
-     chrome routes through tokens.
- **`SplashFadable` scaffolding pattern** (introduced in
-  `cacb19c`). Any future overlay that needs to fade `N >> 3`
-  elements together should follow the same shape: one tiny
-  marker carrying the full-alpha base colour, one global query
-  that lerps every marker's alpha each frame, no per-element
-  query plumbing. Cleanly outscales the `Without<X>, Without<Y>`
-  query exclusion pattern that the old splash was hitting at
-  three siblings.
+- **Leaderboard server upsert:** `POST /api/leaderboard/opt-in` is idempotent —
+  calling it when already opted in just updates `display_name`. Safe to call from
+  `handle_display_name_confirm` without tracking a separate "needs update" flag.

-### Canonical remote
+- **`Messages<T>` API (Bevy 0.18.1):** write with
+  `resource_mut::<Messages<T>>().write(value)`; read in tests with
+  `msgs.get_cursor()` + `cursor.read(msgs).next()`.

-`github.com/funman300/Rusty_Solitaire` is the canonical repo.
-Always push there. As of v0.21.0 origin matches local; the next
-push happens when post-cut work accumulates and is ready to roll
-into a v0.21.1 / v0.22.0 cut.
+- **Test input-state pitfall:** `MinimalPlugins` has no input-tick system, so
+  `ButtonInput::just_pressed` state persists across frames unless explicitly cleared
+  with `input.release(key); input.clear()` between updates.

-### Design direction (Terminal — base16-eighties)
+- **`/play` debug bridge design:** `play.html` runs two independent WASM instances in
+  `Promise.all([bootstrap(), init()])`. `bootstrap()` sets `window.__FERROUS_DEBUG__`
+  (logic layer via `solitaire_wasm.js`); `init()` starts the Bevy canvas. The bridge
+  operates its own `SolitaireGame` — moves applied through the bridge do NOT affect
+  the Bevy visual game. This is intentional for automation/invariant checking.

- **Tone:** retro-terminal / synthwave — flat depth (no box-shadows),
-  monospaced-forward typography (JetBrains Mono / FiraMono), tight
-  16 px edge margins, 8 px card radius.
- **Palette:** near-black surface ramp (`#151515` / `#202020` /
-  `#2a2a2a` / `#353535`), brick-red primary CTA (`#a54242` —
-  swapped from cyan `#6fc2ef` in v0.21.0 commit `a292a7e`), lime
-  success (`#acc267`), gold warning (`#ddb26f`), pink error /
-  suit-red (`#fb9fb1`), lavender celebration (`#e1a3ee`), teal
-  info (`#12cfc0`).
- **Two-color suits.** Red = `#fb9fb1`, black = `#d0d0d0`.
-  Outlined glyphs for diamonds & clubs are *always on*; the
-  Settings "color-blind mode" toggle swaps red → lime `#acc267`
-  (was red → cyan pre-v0.21.0; lime is the next-best non-red
-  base16-eighties accent now that the primary itself is red).
- **Card glyphs render upright in both corners** — no 180°
-  inverted-corner-indicator rotation. Single-orientation
-  digital play doesn't benefit from the traditional flip-
-  readback convention. `design-system.md` § Game Cards
-  documents this deliberate deviation.
+- **HiDPI Bevy canvas:** `WindowResolution::default().with_scale_factor_override(1.0)`
+  is set in the canvas app. Without this, physical pixels exceed WebGL2's 2048px limit
+  on HiDPI displays, causing an immediate wgpu panic on the first resize event.

-READ FIRST (in order, before doing anything):
-  1. SESSION_HANDOFF.md  — this file
-  2. CHANGELOG.md        — [0.21.6] section is the most recent cut
-  3. CLAUDE.md           — unified-3.0 rule set

-     scope; needs an Android device or emulator running.
-  B. Replay-overlay screen-takeover redesign — nearly complete
-     after 12 commits across v0.21.4-6. Scrub bar with notches
-     + labels + WIN MOVE marker, pause / resume / step / stop
-     buttons, Space + Esc + ← / → keyboard accelerators with
-     continuous scrub on hold, keybind-hint footer, full HC-mode
-     coverage on the banner pieces, and a brand-new bottom-edge
-     Move Log panel with a 5-row prev/active/next window all
-     ship. The only remaining major B-2 sub-piece is the
-     **mini-tableau preview** — the mockup's "Game Peek Band"
-     at 50 % opacity showing the tableau through the replay
-     chrome. Implementation needs a settings-aware dim overlay
-     or alpha modulation on the tableau cards during replay.
-     Architectural — touches `card_plugin` rendering. Best
-     tackled in a fresh session because it crosses into a
-     plugin the recent B-2 work hasn't touched. Mockup at
-     `docs/ui-mockups/replay-overlay-mobile.html`.
-  C. Phase 8 (sync) — local storage scaffolding, self-hosted
-     Axum server, `SolitaireServerClient` impl, GPGS stub
-     wired into Settings. The biggest open arc by scope; rolls
-     up several Phase Android dependencies (Keystore,
-     ClipboardManager).

-WORKFLOW NOTES:
-  - Use the system git config (already correct).
-  - When attributing playtester feedback in commits/docs, use
-    "Quat" not "Rhys" (saved feedback memory).
-  - Sub-agents stage + verify only; orchestrator commits.
-  - Every commit must pass build / clippy / test before pushing.
-  - Push to GitHub (origin) — gh auth setup-git wired on
-    primary dev box; verify on laptop before first push.
-  - Token-port pattern: when migrating tokens, walk every
-    concrete artifact downstream of the token (PNG textures,
-    embedded SVGs, hardcoded literals, comment color names),
-    not just the token name. v0.21.0 surfaced three "the
-    migration walked past this" follow-ups that all matched
-    this shape — codified here so future similar work can
-    pattern-match instead of rediscovering.
-  - Doc-vs-implementation drift pattern: v0.21.1's pile-marker
-    visibility fix (`4d48cad`) implemented an invariant that
-    had been declared in a module doc comment but was never
-    enforced in code. When future work touches a module with
-    a "this does X" doc comment, verify the code actually does
-    X and add a test if not. Two layers, two checks.
-
-OPEN AT THE START: ask which of A–C. Don't pick unilaterally.
-Note: every remaining option is multi-session by nature (A is
-gated on Android tooling, B and C are explicitly multi-session
-arcs). A fresh session is a better fit for any of them than the
-tail of a long working stretch.

+- **`/play-classic` vs `/play` in e2e:** `smoke.spec.js` + `gameplay_review.spec.js`
+  target `/play-classic` (DOM-heavy game.html); `play_canvas.spec.js` targets `/play`
+  using only the `__FERROUS_DEBUG__` bridge (no DOM selectors). `cycle_metrics.js`
+  supports both via `--route play-classic|play`.
