-# Plugin Safety Harness
-
-Renders a plugin across **every declared screen (mode)** and **a spread of
-matrix sizes**, and fails if any combination crashes, draws past the panel edge,
-or — for plugins that ship golden images — drifts visually. The goal: change a
-plugin without breaking a size or screen you didn't think to test.
-
-## Sizes: a sample, not a fixed list
-
-There is **no fixed set of supported panel sizes** — an RGB matrix build can be
-any width/height and configuration (square, rectangle, 2×2, 4×4, 8×2, long
-strips, tall stacks). Plugins are expected to read dimensions dynamically
-(`self.display_manager.matrix.width/height`) and lay themselves out
-accordingly, so a hardcoded coordinate or unscaled font shows up as a failure
-here.
-
-The harness therefore renders against a **representative sample** that spans the
-axes of variation (`DEFAULT_TEST_SIZES` in `src/plugin_system/testing/sizes.py`),
-not an authoritative list:
-
-Each module is 64×32; entries are real panel-grid arrangements (cols × rows):
-
-| Size    | Grid | Why it's in the sample                     |
-|---------|------|--------------------------------------------|
-| 64×32   | 1×1  | single panel — tightest common rectangle   |
-| 128×32  | 2×1  | the baseline most plugins are tuned for    |
-| 64×64   | 1×2  | stacked — tall-narrow centering            |
-| 128×64  | 2×2  | block — icon scaling / vertical centering  |
-| 256×32  | 4×1  | long strip — wide horizontal layout        |
-| 128×96  | 2×3  | tall — vertical overflow                   |
-| 256×128 | 4×4  | large block — both dimensions big at once  |
-
-**Override the sizes entirely** to test your actual hardware (or any shape):
-
-```bash
-# CLI — one-off:
-python scripts/check_plugin.py --plugin clock-simple --sizes 8x16,64x64,256x32
-
-# pytest — force every plugin onto your panel(s):
-LEDMATRIX_TEST_SIZES="8x16,128x128" pytest test/plugins/test_plugin_matrix.py
-
-# Per-plugin — declare the shapes a plugin targets in its test/harness.json:
-#   { "sizes": [[8, 16], [64, 64]] }
-```
-
-Precedence: `LEDMATRIX_TEST_SIZES` env (global) → per-plugin `harness.json`
-`sizes` → the default sample. Bounds checking adapts to whatever sizes a run
-uses — the backing canvas is padded out to the **largest** panel in the run, so
-a coordinate meant for a big build is still caught when rendering a small one.
-
-## Quick start
-
-```bash
-# Functional + bounds check across all sizes/screens:
-python scripts/check_plugin.py --plugin clock-simple
-
-# Every discovered plugin:
-python scripts/check_plugin.py --all
-
-# Dump PNGs to eyeball each size/screen:
-python scripts/check_plugin.py --plugin ledmatrix-weather --out-dir /tmp/preview
-```
-
-Exit code is non-zero if any `(plugin, size, screen)` fails. Plugins are
-discovered in `plugin-repos/` and `plugins/` (override with `--plugin-dir`).
-
-## What it checks (Phase 1 — always on)
-
-1. **Loads** and builds its mode list.
-2. **Renders every screen** at every size without raising. `update()` may fail
-   (no network in CI) and is tolerated; a crash in `display()` is a failure —
-   `display()` must handle the no-data state.
-3. **Bounds**: nothing is drawn past the right/bottom edge. Implemented by
-   `BoundsCheckingDisplayManager`, which backs the declared panel with an
-   oversized canvas and flags any pixels that land in the margin. (Left/top
-   overflow at negative coordinates and BDF text are not flagged — golden images
-   cover those.)
-
-## Golden images (Phase 2 — opt-in per plugin)
-
-A plugin opts in by committing reference PNGs and (usually) a small harness spec:
-
-```
-plugins/<id>/test/harness.json          # how to render deterministically
-plugins/<id>/test/fixtures/mock.json     # optional cached data
-plugins/<id>/test/golden/<WxH>/<mode>.png
-```
-
-`test/harness.json` keys (all optional):
-
-```json
-{
-  "config":      { "timezone": "UTC" },
-  "mock_data":   "fixtures/mock.json",
-  "freeze_time": "2025-08-01 15:25:00",
-  "skip_update": false,
-  "sizes":       [[128, 32], [128, 64]]
-}
-```
-
-Generate / refresh goldens after an intentional visual change, then review the
-diff before committing:
-
-```bash
-python scripts/check_plugin.py --plugin clock-simple --update-golden \
-  --config '{"timezone":"UTC"}' --freeze-time "2025-08-01 15:25:00"
-```
-
-Comparison is exact by default (`compare_images` in `harness.py` accepts a
-tolerance for known anti-aliasing noise). Determinism requires a pinned Pillow
-and the bundled fonts — keep both stable when regenerating goldens.
-
-## Tests & CI
-
-- `test/plugins/test_harness.py` — unit tests for bounds detection, image
-  comparison, and mode enumeration (run anywhere).
-- `test/plugins/test_plugin_matrix.py` — parametrized over discovered plugins ×
-  sizes × screens; honors each plugin's `test/harness.json` and goldens. Skips
-  when no plugins are present (e.g. a fresh core checkout); set
-  `LEDMATRIX_REQUIRE_PLUGINS=1` in a pipeline where plugins must be present to
-  turn an empty discovery into a hard failure instead. Point it at the monorepo
-  with `LEDMATRIX_PLUGINS_DIR=/path/to/ledmatrix-plugins/plugins`.
-- `.github/workflows/test.yml` — runs the harness + visual tests on every PR.
-
-The plugin monorepo has its own `Plugin Safety` workflow that runs this harness
-against changed plugins on every PR.
-
-## Developer workflow
-
-1. Change the plugin on a branch.
-2. `python scripts/check_plugin.py --plugin <id> --out-dir /tmp/preview` and
-   eyeball the PNGs.
-3. Intentional visual change? `--update-golden`, review diffs, commit goldens.
-4. (Monorepo) bump `manifest.json` version and let the pre-commit hook sync
-   `plugins.json`.
-5. Push — CI re-runs the harness across all sizes and gates the PR.

-Two storage tiers
------------------
-* **Memory tier** (:class:`~src.cache.memory_cache.MemoryCache`): fast LRU

-Key responsibilities
---------------------
-* Initialise the ``RGBMatrix`` (hardware) or ``RGBMatrixEmulator`` depending
-  on the ``EMULATOR`` environment variable.
-* Expose a PIL ``Image``/``ImageDraw`` canvas that plugins draw into, then
-  flush it to the matrix via double-buffering (:meth:`DisplayManager.update_display`).
-* Load and cache TTF/BDF fonts; expose ``draw_text`` for consistent text rendering.
-* Provide ``width`` / ``height`` properties — always use these instead of
-  hard-coding display dimensions.
-* Write periodic PNG snapshots to ``/tmp/led_matrix_preview.png`` for the
-  web-interface live preview.
-* Track scrolling state and gate deferred updates so plugins don't race with
-  an in-progress scroll.
-
-Singleton: only one ``DisplayManager`` instance exists per process.  The
-first call to ``DisplayManager(config)`` creates it; subsequent calls return
-the same object.

-Font Manager — TTF/BDF font loading, caching, and dynamic registration.
-
-:class:`FontManager` serves two purposes:
-
-1. **System fonts** — loads the configured small/medium/large TTF fonts (and
-   their BDF bitmap equivalents) at startup, caches metrics, and exposes them
-   via ``DisplayManager`` attributes (``small_font``, ``medium_font``, etc.).
-
-2. **Plugin fonts** — lets plugins register their own fonts at runtime via
-   :meth:`FontManager.register_manager_font` and resolve them later via
-   :meth:`FontManager.resolve_font`.  Registered fonts are namespaced by
-   plugin ID so they cannot collide.
-
-Font sources
-------------
-* Local paths relative to the project root.
-* Remote URLs — downloaded once, cached to disk, and never re-fetched while
-  the cached copy is fresh.
-
-BDF fallback
-------------
-Pixel-accurate LED fonts are stored as ``.bdf`` (Bitmap Distribution Format)
-files.  When PIL cannot measure BDF glyphs natively, ``freetype-py`` is used
-for accurate width/height calculations.

-Bounds-checking display manager.

-A VisualTestDisplayManager that draws onto an oversized canvas (the declared
-panel size plus a right/bottom margin) while still reporting the declared size
-to the plugin. Content that a plugin draws past the right or bottom edge lands
-in the margin instead of being silently clipped by PIL, so the harness can
-detect overflow — the classic symptom of hardcoded coordinates or fonts/icons
-that don't scale down to a smaller panel.
-
-Limitations (documented on purpose):
-- Overflow past the LEFT or TOP edge (negative coordinates) is still clipped by
-  PIL and not detected here. The dominant real-world breakage is content that is
-  too wide/tall for a smaller panel, which this catches.
-- BDF text is clipped to the declared bounds by the parent's bitmap drawer, so
-  BDF overflow is not flagged. Golden-image regression covers those plugins.
-- If a plugin replaces the canvas with its own image (display_manager.image = ...),
-  the margin can't be measured and overflow is reported as undetermined (None).
