fix(composer): coerce prefixed colour channels, non-finite numbers, marquee ids

Three more routes into the generated source, plus a fix to one of my own tests
that was checking the wrong branch.

Prefixed colour channels were interpolated raw
----------------------------------------------
Five tuples were built without coercion:

    p['fill_tuple']  = f"({el.get('r', 100)}, {el.get('g', 200)}, ...)"
    p['empty_tuple'] = f"({el.get('emptyR', 50)}, ...)"
    p['label_tuple'] = f"({el.get('labelR', 200)}, ...)"

so progress_bar, pips, sparkline and gauge took arbitrary expressions the same
way width/height did. Confirmed: every one of the five put __import__ into the
generated source. They now go through a new _rgb_tuple helper, which _rgb_expr
also delegates to.

The pre-existing colour test only covered r/g/b on a text element, which is why
the prefixed channels and these four types were never exercised.

Non-finite numbers escaped as a 500
-----------------------------------
json.loads accepts Infinity/-Infinity/NaN by default and Flask's get_json
passes them straight through, so a payload can hand _safe_int a non-finite
float. int(inf) raises OverflowError, which is neither ValueError nor
ComposerInputError, so it escaped both handlers and surfaced as a 500 with a
traceback rather than a 422. Verified end to end through Flask's parser.

Marquee ids reached the source as identifiers
---------------------------------------------
data_key is spliced UNQUOTED into variable names (_{{ data_key }}_text = ...)
and only '-' was normalised. A punctuated id landed in the generated source as
code. ast.parse caught it, so this was not exploitable, but the caller got an
opaque "Generated code has a syntax error" instead of being told the id was
unusable -- the same failure mode as the empty-block bug. Now restricted to
identifier characters and bounded to 64.

The line-anchor test was testing the wrong branch
-------------------------------------------------
test_line_branch_applies_the_anchor_offset searched the whole file for
"case 'line': {". getBoundingBox has one too and comes first, so the assertion
was reading the bounding-box branch: stripping the anchor offset from
_drawElement left all 11 checks green. Both line tests are now scoped to their
own function via tree-sitter, so they cannot be satisfied by the same branch.

Tests: 35 of the injection suite's checks fail against the reverted fixes; the
scoped line test fails when _drawElement's offset is removed. Full suite 4059
passed, the one failure being test_install_lowmem (pre-existing, awaiting #492).

-## 3.3.0
-
-**The release the sports scoreboards floor on to delete their bundled copies.**
-3.2.0 shipped the unified sports library and made `ledmatrix_min_version`
-enforceable; this ships the last three shared modules and completes the store
-gate, so a scoreboard can now floor here and carry no fallback at all.
-
-New modules a plugin may import via `src.*` and floor on 3.3.0 for:
-
-- `src/common/sports_card.py` — settings, colour, font and date helpers for a
-  scoreboard's `game_renderer.py`. Free functions taking `config`/`fonts`
-  explicitly, so nothing about the caller's class is assumed.
-- `src/common/sports_game_renderer.py` — `SportsGameRendererMixin`: scroll/Vegas
-  card geometry (centre gap, logo slot and cache key, layout offsets, the
-  upcoming-card date and time layout). No `__init__` and no state, so adoption
-  is one line on the class statement.
-- `src/common/sports_shared.py` — `SportsCoreSharedMixin`,
-  `SportsLiveSharedMixin`, `SportsRecentSharedMixin`: the `sports.py` bodies
-  byte-identical in all eight lineage-sharing scoreboards.
-
-All three sit under `src/common/` rather than `src/base_classes/sports/`,
-deliberately: importing that package pulls `core.py` → `DisplayManager` →
-`rgbmatrix`, and these are pure logic. Plugins importing them must not acquire a
-hardware dependency.
-
-Three notes for anyone adopting `sports_shared`:
-
-- `SportsRecentSharedMixin` defines `__init__`. Its bare `super()` binds to the
-  mixin, so it reaches the host only when the mixin is listed **first** in the
-  bases. Reversing that order silently skips the host constructor.
-- Methods that resolve the plugin's `config_schema.json` use `_plugin_dir()`,
-  which walks the MRO rather than reading `__file__` — `__file__` is now
-  `src/common/`. It walks because `SportsCore` is an ABC: a subclass built with
-  `type(name, bases, ns)` reports `__module__` as `"abc"`.
-- `_get_timezone`, `_extract_game_details` and `_fetch_data` are byte-identical
-  across the eight but stay in the plugins. The first binds a per-plugin
-  timezone module whose contents differ; the other two are the abstract stubs
-  that define the sport.
-
-**The store's compatibility gate is now on every registry-managed route.** 3.2.0
-gated `install_plugin`. This release gates the git-pull update path and
-`install_from_url`, so a plugin whose floor the core cannot meet is refused
-after download with no partial directory left behind.
-
-### Fixed
-
-- **ESPN 403s.** `site.api` began rejecting the User-Agent strings this repo
-  sent on 2026-08-04; every shared-data-source scoreboard returned
-  `403 Forbidden`. Requests now send an identifying token with a project URL —
-  browser-style strings and bare custom tokens are both refused.
-- **Low-memory boards becoming unreachable under load** while still answering
-  pings and serving the web UI. Fetched payloads are released after delivery
-  rather than pinned on the completed request for up to an hour, malloc arenas
-  are capped, and log volume and SD writes are reduced. Available memory is now
-  reported in Tools diagnostics.
-- **A failed logo download pinning a team to a grey box**: the placeholder was
-  written under the real logo's filename, so later attempts found a file and
-  reported success without retrying.
-- **A plugin enabled but never loaded is retried** rather than staying absent
-  with `error = null`.
-- `ttl` now controls cache expiry; abandoned cache writes no longer leave temp
-  files; one cache-cleanup thread per directory rather than per manager.
-- Odds are fetched for the games displayed, not the whole schedule window, and a
-  stalled ESPN no longer stalls the whole plugin update.
-- Array-item secrets are no longer wiped or logged.
-- A restored backup matches the device it was taken from.
-- The web UI reports the real error instead of "unknown", rejects non-finite
-  JSON numbers, and stops checkbox groups posting back hidden options.
-
-### Added
-
-- `display.hardware.orientation` for panels mounted upside down.
-- Vegas keeps live content in the ticker rather than being preempted by it.
-- Schemas can label enum dropdown options.

-
-**What shipped.** Eight plugins, ~5,800 lines of frozen fallback deleted. Each:
-copy removed, guarded import collapsed to a plain one, floor raised to 3.2.0,
-`test_core_fallback.py` rewritten as `test_core_scroll.py` asserting the sunset
-rather than the fallback. `scripts/check_scroll_adoption.py` gained
-`sunset_violations` and a `SUNSET_PLUGINS` set naming all eight, so a
-resurrected copy or a returned guard fails CI.
-
-Delivered as plugins #346 (hockey, later folded into #351), #349 (football),
-#350 (baseball), #351 (the remaining six).
-
-**Two things found by doing it, both worth carrying forward:**
-
-- **Only one fallback held orchestration logic the core lacked.** baseball's
-  `_configure_scroll_helper` reinterpreted `scroll_speed` as pixels-per-*frame*
-  when `speed × delay` fell outside the 0.1–5.0 window — measured, 10–20×
-  faster than configured for a speed between 1.0 and 5.0. Standardised onto the
-  core's behaviour (honour the documented px/sec, clamp) rather than preserved.
-  Every other difference across the eight was a docstring, an unreachable
-  `scroll_helper is None` guard, or an equivalent diagnostic.
-- **Two tests had been leaning on the guard without anyone knowing.**
-  `soccer/test_live_screens.py` stubbed `src` in a way that shadowed the core,
-  so its guarded import fell back and the test had been exercising the *frozen
-  copy* rather than the shipping class since B5. Before sunsetting anything else
-  that carries a guarded core import, grep for tests that stub `src`.
-
-**The floor-raising traps still apply** to any future sunset: four plugins
-declare their floor top-level, where editing `versions[0]` is a silent no-op,
-and the floor has three live spellings (`min_ledmatrix_version`,
-`requires.min_ledmatrix_version`, `versions[].ledmatrix_min_version`, plus
-deprecated `ledmatrix_min`). See
-`src/plugin_system/compatibility.py:declared_min_version` for the resolution
-order any floor-raising tool must reproduce — and note the name is **inverted**
-between the top level and `versions[]`.
-
-**Still not adopted, deliberately:** `data_sources.py`, `game_renderer.py` and
-`base_odds_manager.py`. The standing decision held them until B6 closed; it now
-has, so they can be reconsidered — with B5's lesson applied, which is to build
-the object and diff rendered output rather than trust a static check.
-
-### B5 retrospective — what the adoption actually cost
-
-Recorded because it is the evidence behind the two decisions above, and because
-"the adoption went fine" is not what happened.
-
-**Four of the eight shipped with scroll mode broken** on a 3.2.0 core, and were
-repaired in plugins-repo #251. The restructure lifted the content methods
-verbatim but left the state they read off `self` behind: separator-icon
-constants (hockey, basketball, lacrosse) and the game-renderer cache (afl).
-hockey/basketball/lacrosse could not construct the scroll display at all; afl
-raised inside `prepare_scroll_content`, which the core base *catches*, so its
-only symptom was scroll mode silently drawing nothing.
-
-Three things are worth carrying forward:
-
-- **The bundled fallback did not protect anyone from this.** The break was on
-  the modern path, which the fallback never touches. Carrying the second copy
-  bought nothing against the actual defect while creating the divergence that
-  produced it. That is an argument *for* B6, not against it.
-- **Every gate was green.** The safety harness renders the scoreboard screens,
-  not scroll mode; `test_core_fallback.py` checked that methods existed and that
-  their *globals* resolved, and `self.NHL_SEPARATOR_ICON` is an attribute read,
-  invisible to an AST scan for `Name` loads. The fix was to stop reasoning about
-  source and **build the object**: construct both classes on both paths, compare
-  the separator icons they end up with, and assert the adopted class ends up
-  with every instance attribute the bundled one sets.
-- **Test what the change touches, not what is convenient to render.** Scroll
-  mode had no coverage because the harness could not reach it. A comparison
-  harness that renders the same games through both paths and diffs the pixels
-  needs no per-sport knowledge of the right answer, only that adopting core code
-  did not change it.
-
-**The ledger.** Before adoption, eight duplicated copies totalled 5,685 lines.
-After adoption plus the frozen legacy copies it was 10,610; removing the dead
-inline duplication (plugins #252) brought it to roughly 8,620. B6 would take it
-to about 3,300 including the shared core module — some 2,400 fewer than before
-this project started. **Until B6 runs, the adoption is net negative on disk**,
-and its one delivered user-visible gain is that adopted plugins honour the
-global `target_fps` instead of hardcoding ~100 FPS.
-
-### Decision: stop adopting further modules until B6 closes
-
-`data_sources.py` (9 copies), `game_renderer.py` (8) and `base_odds_manager.py`
-are the obvious next candidates. **Do not adopt them yet.** Each adoption adds
-carrying cost — a second copy to keep in step — against a payoff that is
-contingent on B6, and B6 is gated on an installed base we cannot currently
-measure. Consolidate what is already committed; revisit when B6 does.
-
 ## What's next
 
-Steps 1–5 of the original plan are **done**: 3.2.0 is tagged and published with
-a version number CI now asserts (#428), the compatibility gate is in
-`install_plugin` and reads `compatible_versions` as well as the floor
-(#431, #433), the newest manifest entry is required to use `ledmatrix_min_version`
-(plugins #244), and all eight plugins have adopted the scroll orchestration
-(plugins #245–#249, repaired in #251, tidied in #252).
+In order. Each step is independently useful and independently revertible.
 
-What actually remains, smallest first:
-
-1. **Soak the adoptions on hardware.** football and hockey have been run on a
-   live rig through real games; baseball was watched through one earlier. The
-   rest are proven by harness, unit tests and pixel comparison. Out-of-season
-   sports cannot be soaked until their season starts. When you do, **check the
-   rig's `*_display_mode` first** — a board in `switch` mode will happily load a
-   sunset plugin and tell you nothing about the scroll code the sunset changed.
-2. **Cut 3.3.0.** Not required by B6 — its floors are 3.2.0, which is released —
-   but `calendar` 1.2.3 floors at 3.3.0 for the device-authorization endpoints
-   that landed after 3.2.0, so it is un-installable until the release exists.
-3. **Reconsider the held modules** (`data_sources.py`, `game_renderer.py`,
-   `base_odds_manager.py`) now that the sunset has closed. `game_renderer.py` is
-   the largest single duplication left: ~11,500 lines across eight plugins, with
-   ~36,500 more in the eight `sports.py`. Note that core already ships
-   `src/base_classes/sports/` (~143KB, promoted in B1/B2) that **no plugin
-   imports** — check whether it has drifted before treating it as the target.
+1. **Tag and publish v3.2.0.** The code is already on `main` (`21825cbf`).
+   Nothing else blocks this, and it is what makes `ledmatrix_min_version:
+   "3.2.0"` refer to something real.
+2. **Make the version number honest.** Have the release process assert that the
+   tag, the GitHub release, and `src.__version__` agree — a check in CI is
+   cheaper than the confusion of the last two releases. Then revisit the
+   `< 2.0.0` skip in `_warn_if_incompatible`, which currently silences the
+   warning for the users who most need it.
+3. **Add the compatibility gate** to `StoreManager.install_plugin` and
+   `.update_plugin`: refuse a plugin whose declared floor exceeds
+   `src.__version__`, and surface the reason in the store UI rather than only
+   the log. This is the single change that turns the floor from documentation
+   into a guarantee, and B6 depends on it.
+4. **Migrate the manifests** to `ledmatrix_min_version`, and reconcile them with
+   `compatible_versions` (see above — that field is the required, canonical one,
+   and the gate does not read it yet). Currently 28 plugins spell the floor both
+   ways across their `versions[]` entries, 12 use only the old spelling, and 2
+   only the new. Scope the sweep to the nine sports plugins if a 42-plugin
+   version-bump wave isn't worth it — but the `compatible_versions` half has to
+   cover every manifest the gate can refuse, or define explicit legacy handling,
+   before the gate is allowed to block anything.
+5. **Run B5 adoption** — hockey, soccer, football, then the remaining six.
+   Bundled copies stay. Byte-identical harness output per plugin, then a soak.
+6. **Only then plan B6**, with the compatibility regression test described above
+   in CI first.

-"""The scroll/Vegas card geometry the sports scoreboards all share.
-
-Eight scoreboards -- afl, baseball, basketball, football, hockey, lacrosse,
-nrl and soccer -- each carried their own ``game_renderer.py``. After the card
-helpers moved to ``src/common/sports_card.py`` the settings lookups were
-shared, but the *geometry* was not: nine methods that decide how wide the
-centre gap is, how much room a logo gets, and where an upcoming card's date
-and time land were still eight separate copies. Five were byte-identical
-across all eight plugins; the other four were identical in seven, with a
-different single outlier each time.
-
-That last detail is why this is a mixin rather than free functions. There is
-no per-sport branching to write -- baseball needs its own
-``_draw_upcoming_game_status`` and ``_logo_slot_width``, hockey its own
-``_upcoming_date_and_time``, football its own ``_score_reserve_width``, and
-every one of those is an ordinary override. The seven that agree inherit and
-say nothing.
-
-It is deliberately *only* a mixin: no ``__init__``, no state of its own. The
-plugins' constructors differ in six ways and none of that difference is worth
-unifying, so adoption is one line on the class statement plus deleting the
-methods that now come from here.
-
-What a host class must provide
-------------------------------
-Attributes: ``display_width``, ``display_height``, ``config``, ``fonts``,
-``logger``, ``_team_rankings_cache``.
-
-Methods: ``_draw_text_with_outline(draw, text, position, font, fill=None,
-outline_color=(0, 0, 0))`` -- the one hook whose body genuinely varies -- plus
-the ``sports_card`` delegations ``_scroll_card_option``,
-``_upcoming_center_mode``, ``_vs_text``, ``_element_color``,

-"""A delivered fetch payload must not stay resident on the stored result.
-
-BackgroundDataService kept the fetched body on the FetchResult it filed in
-`completed_requests`, which is swept only hourly and capped at 500 entries by
-count. For status records that is free; for a season schedule it is not. NCAA
-football's 2026 schedule is 946 games, and on a 1GB Pi 3B+ the parsed payload
-measured ~90MB -- a tenth of the board's memory, pinned for an hour after the
-consumer had already been handed it.
-
-The cache-hit path was the worse of the two. It runs once per update interval
-per sport, mints a fresh request_id each time, and hands back whatever the
-cache returns -- so a memory-tier miss (the tier is capped at 150 entries)
-re-parses the payload from disk into a genuinely new object. Those accumulate
-as separate copies rather than shared references, which is the staircase seen
-in the field: RSS stepping up ~90MB per sport as seasons loaded and never
-coming back down.
-
-Releasing is safe because the payload is written to the cache under the
-request's cache_key before the result is built, and that is where consumers
-read it from -- the callback is handed the object directly and the plugins use
-it only in passing before reading the cache back.
-
-Requests submitted *without* a callback keep their payload: polling
-get_result() is then the only way to collect it, so releasing would break that
-contract.
-
-And the release must happen after EVERY callback, not after each one. Callers
-that joined an in-flight fetch share a single FetchResult, so releasing per
-delivery strips the payload out from under everyone still queued -- see
-TestJoinersAllGetTheData.

-"""The shared sports.py mixins: their host contract, and _plugin_dir.

-Two things are worth testing here and the rest is not. The 45 method bodies
-moved verbatim from the plugins, so they are covered by the plugins' own tests
-and by 176 byte-identical safety-harness renders. What is genuinely new is:
-
-1. The contract. Every ``self.<CONSTANT>`` a mixin reads must be defined on the
-   mixin, or a host that does not happen to declare it raises AttributeError at
-   runtime. Two were missed on the first pass (_QUALITY_CHOICES and
-   _RANKING_COVERAGE_SECONDS); the eight plugins all declare them, so nothing
-   failed -- it would only have bitten a ninth. The test derives the list rather
-   than restating it, so the next omission fails here instead of in the field.
-
-2. ``_plugin_dir``. This is the only line of genuinely new logic in the move. In
-   sports.py these methods found config_schema.json with ``__file__``; here that
-   is src/common/, so the plugin directory has to be recovered from the
-   instance -- and getting it wrong is silent, costing grid-snapped font sizes
-   (measured at 81% anti-aliased edges) rather than raising.

-"""What happens to an adopted sports plugin on each core it can meet.
-
-B5 moved the eight scoreboards onto `src.common.sports_scroll` behind a guarded
-import, keeping a bundled copy as the fallback. B6 deletes those copies. The
-two phases make *different* promises, and only the second one is obvious:
-
-|                    | bundled copy present            | bundled copy removed        |
-|--------------------|---------------------------------|-----------------------------|
-| **pinned old core**| loads -- B5's whole guarantee   | ERROR, naming the module    |
-| **current core**   | loads, using core code          | loads, using core code      |
-
-The top-left cell is the one worth having: nothing else in this suite proves an
-adopted plugin still runs on a core that predates the module, and that claim is
-the entire basis for having shipped B5 ahead of B6's gate.
-
-The bottom-left cell is the B6 failure mode, and it is asserted through
-`PluginManager.load_plugin` rather than a bare import on purpose. The manager
-catches the `ModuleNotFoundError`, so nothing propagates to a caller: a test
-that expected `pytest.raises` would pass against a core where the module is
-merely *broken* rather than absent, and would say nothing about what the user
-actually experiences. What they get is a plugin parked in ERROR and one log
-line -- which is precisely why B6 needs the install gate rather than trusting
-the failure to be noticed.
-
-This covers the load path. The install/update gate -- which is what should stop
-a sunset plugin reaching an old core in the first place -- is the other half of
-the guarantee and is tested in test_plugin_compatibility_gate.py.
-
-See docs/SPORTS_UNIFICATION.md, "B6 -- why the sunset needs more than a version
-floor".
