The phase table had B4 as "next" and B5 as "after B4" while both had shipped, and described B6 as blocked on B4's gate — which is now merged and released. A plan that misreports which phase it is in is worse than no plan: the next person reads it and repeats finished work.

Corrected, and three things that were only ever decided in conversation are now written down.

B6 is deliberately held

3.2.0 was published 2026-08-03; 3.1.0 ran nine months before it. B6's premise is that cores without src.common.sports_scroll are gone, and there is no release-asset count or install telemetry to demonstrate that. Running it now strands users on their current plugin versions.

The gate that makes B6 safe is already built and tested — it refuses installs whose floor exceeds the core version, and refuses floors above 2.0.0 on a core reporting an untrustworthy version. It is the calendar that is missing, and no amount of further code changes that. Also records the traps for whoever runs it: four plugins declare their floor top-level where editing versions[0] is a silent no-op, and the floor has three live spellings.

Stop adopting further shared modules

data_sources.py (9 copies), game_renderer.py (8), base_odds_manager.py. Each adoption adds a second copy to keep in step against a payoff contingent on B6.

A B5 retrospective

Because "the adoption went fine" is not what happened — four of eight plugins shipped with scroll mode broken on a 3.2.0 core (repaired in plugins #251, tidied in #252). Three points worth carrying forward:

  • The bundled fallback did not protect anyone from this. The break was on the modern path, which the fallback never touches. That is an argument for the sunset, not against it.
  • Every gate was green. The harness renders scoreboard screens, not scroll mode; the AST check looked for unresolved globals and self.NHL_SEPARATOR_ICON is an attribute read. The fix was to stop reasoning about source and build the object.
  • The ledger: 5,685 lines before adoption → 10,610 after → ~8,620 once the dead duplication was removed → ~3,300 after B6. Until B6 runs the adoption is net negative on disk, with one delivered user-visible gain (native target_fps).

Also replaces the "what's next" list, whose first five items were all done, with what actually remains: the stale plugin-test tranche, hardware soaks for the six unsoaked adoptions, and a CLAUDE.md panel-size fix.

Documentation only — no code changes.

Summary by CodeRabbit

  • Documentation
    • Updated rollout tracking to show B4 and B5 as complete and B6 sunset across all scoreboards.
    • Documented the safeguards that enabled the sunset and the removal of legacy fallback behavior.
    • Added a retrospective on adoption issues, floor-raising pitfalls, and modules not yet adopted.
    • Replaced the prior action plan with remaining work, including hardware soak testing and the 3.3.0 release.

The phase table had B4 as "next" and B5 as "after B4" while both had shipped,
and described B6 as blocked on B4's gate — which is now merged and released. A
plan that misreports which phase it is in is worse than no plan: the next
person reads it and repeats finished work.

Corrected, and three things that were only ever decided in conversation are now
written down:

  * **B6 is deliberately held.** 3.2.0 published 2026-08-03; 3.1.0 ran nine
    months before it. B6's premise is that cores without the module are gone,
    and there is no release-asset count or install telemetry to show that.
    Running it now strands users on their current plugin versions. The gate
    that makes it safe is already built and tested — it is the calendar that is
    missing, and no amount of further code changes that.
  * **Stop adopting further shared modules** (data_sources, game_renderer,
    base_odds_manager) until B6 closes. Each adoption adds a copy to keep in
    step against a payoff contingent on B6.
  * **A B5 retrospective**, because "the adoption went fine" is not what
    happened: four of eight shipped with scroll mode broken on a 3.2.0 core.
    The bundled fallback did not protect against it — the break was on the

📝 Walkthrough

Walkthrough

The rollout documentation now records B4, B5, and B6 completion, the 2026-09-01 sunset, B5 adoption defects and repairs, lifted module holds, and remaining work.

Changes

Sports unification rollout

Layer / File(s) Summary
Rollout status and B6 sunset
docs/SPORTS_UNIFICATION.md
B4, B5, and B6 are marked complete. The document records store refusal protections on all three install and update routes, the removal of approximately 5,800 lines of fallback code, compatibility regression coverage, and two sunset findings.
Adoption retrospective and remaining work
docs/SPORTS_UNIFICATION.md
The B5 retrospective records scroll-mode defects in four of eight adoptions and their repairs. The hold on data_sources.py, game_renderer.py, and base_odds_manager.py is lifted. Remaining work includes hardware soak testing, the 3.3.0 release, and reconsideration of those modules.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 9e1c3

The document currently gives conflicting guidance about whether sideloaded installs are gated, which could mislead someone planning the B6 sunset. The PR is otherwise mergeable, but this status should be aligned with the current behavior or explicitly followed up.

A line wrapped onto "#433), the newest manifest entry ...", which
markdownlint reads as a malformed ATX heading (MD018). Reflowed so the
line starts with "(#431, #433)" instead.

Not the suggested fix: adding a space after the hash would have turned
the PR reference into "# 433". The B5 safety claim raised alongside this
was already corrected in ac44b5a.

The heading read "B5 — adoption is safe by construction", which this same
document disproves two sections later: four of the eight adopted plugins
shipped with scroll mode broken on a 3.2.0 core and were repaired in
plugins #251.

The body was already careful -- it says fallback compatibility is what is
guaranteed, and that correctness on a core which *does* ship the module
needs object-level and scroll-mode validation. The heading was not, and a
heading is what a reader scanning the plan actually takes away.

Retitled to name both halves, with a sentence up front saying why the
unqualified claim is false and pointing at the retrospective that shows
it. The phase intro said "one of them is safe by construction and the
other is not"; that now says what it actually means -- one cannot break a
user on an old core, the other can.

The second review point, MD018 on the ATX heading at line 409, does not
reproduce: that line now begins "(#431, #433)" rather than "#433)", so
there is no bare-hash heading. `grep -cE '^#+[^ #]'` returns 0 for the
whole file.

Both addressed — one fixed, one not reproducible.

Limit the B5 safety claim — confirmed, and fixed at the heading

You're right that it conflicts. The body was already careful:

That fallback compatibility is safe by construction. On a core that does ship the module, correctness is not automatic — object-level and scroll-mode validation … is required to prove full behavior.

The heading was not: ### B5 — adoption is safe by construction. That's the line a reader scanning the plan takes away, and it says something the retrospective two sections down disproves — four of the eight shipped with scroll mode broken on a 3.2.0 core.

Retitled to name both halves, with a sentence up front saying why the unqualified claim is false and pointing at the evidence:

B5 — the fallback is safe by construction; the modern path is not

The heading matters, because the unqualified version of this claim is false and this document proves it two sections down…

Also fixed the phase intro, which had the same shape — "one of them is safe by construction and the other is not" now reads "one of them cannot break a user on an old core and the other can", which is the distinction actually being drawn.

MD018 on line 409 — does not reproduce

That line has since rewrapped. It now begins (#431, #433), the newest manifest entry… rather than #433), …, so there's no bare-hash heading:

$ grep -cE '^#+[^ #]' docs/SPORTS_UNIFICATION.md
0

Zero for the whole file, so I've left it alone rather than change a line that is already valid.

… done

The remaining-work list had two entries that finished without the doc noticing,
which is the failure mode this file exists to prevent.

- The stale plugin-test tranche is gone. run_plugin_tests.py --all now reports
  174 passed, 2 skipped, 0 failed across the whole fleet. Recorded how to
  re-check it too: these are standalone scripts, not a pytest suite, and one
  calls sys.exit(1) at import, so pointing pytest at a plugin directory
  collapses into an INTERNALERROR that looks nothing like the real state.
- CLAUDE.md already says eight panel sizes.

That leaves the hardware soaks as the only open item needing work rather than
calendar time.

B6's prerequisite is now built -- core test/test_sports_sunset_matrix.py
(#505) -- so the phase table and the regression-test section say so, and the
two modelling traps it had to work through are recorded for whoever touches it
next: the copy-removed shape must be an unguarded import or the failure names
scroll_display_legacy instead of the core module, and only the leaf module may
be hidden because a pre-3.2.0 core still ships src/common/.

The hold itself is re-checked and unchanged: v3.2.0 is still latest,
__version__ is still 3.2.0, no 3.3.0, 23 days rather than the few months the
gate asks for. Also worth stating plainly -- the core updates by git pull, not
by downloading a release, so release-asset counts would not measure uptake even
if we had them. Whatever unblocks this has to come from the store side.

This PR was opened to say B6 was deliberately held. It has since run, so the
document said the opposite of the truth -- which is the exact failure it was
written to fix: "a plan that misreports which phase it is in is worse than no
plan".

Merges current main first (53 commits), which brings in #508's corrections to
this same file, then replaces the hold with what happened.

**Why the hold lifted is worth recording, because the stated gate was never
met.** It asked for evidence of 3.2.0 uptake, and that evidence could not
arrive: the core updates by `git pull --rebase`, so release-asset counts cannot
measure it, and no store-side telemetry exists. What changed is that the risk
the gate protected against was closed directly -- the store now refuses a
plugin whose floor exceeds the running core on all three routes in:
install_plugin (#431/#433), update_plugin's git branch (#508), and
install_from_url (#510). A pre-3.2.0 user cannot receive a sunset plugin at
all, so they keep the version they run. Refusal replaced the bundled copy,
which is what the copy stood in for.

Records what shipped (eight plugins, ~5,800 lines, plugins #346/#349/#350/#351)
and the two findings worth carrying to the next module: baseball's fallback was
the only one holding orchestration logic the core lacked, and two tests had
been leaning on the guard -- soccer's stubbed `src` in a way that shadowed the
core, so it had been exercising the frozen copy rather than the shipping class
since B5.

The remaining-work list is replaced too. Its first item was "nothing on the
critical path, B6 is waiting on calendar time", which is no longer true. What
remains: hardware soaks (with a note to check the rig's display_mode first, or
a board in switch mode tells you nothing about the scroll code), cutting 3.3.0
-- not required by B6, whose floors are 3.2.0, but calendar 1.2.3 floors at
3.3.0 and is un-installable until it exists -- and reconsidering the modules
held back during the sunset.

Keeps the pre-B6 sections as history. The reasoning still applies to the next
module; it is just no longer in force for this one.

Updated — B6 has run, so this now records it rather than deferring it

This PR was opened to say B6 was deliberately held. It has since run, so the document said the opposite of the truth — which is the exact failure it was written to fix: "a plan that misreports which phase it is in is worse than no plan."

Merged current main first (53 commits), which brings in #508's corrections to this same file, then replaced the hold with what happened.

Why the hold lifted, given the stated gate was never met

Worth recording, because the gate asked for something that could not arrive: evidence of 3.2.0 uptake. The core updates by git pull --rebase, so release-asset counts cannot measure it, and no store-side telemetry exists.

What changed is that the risk the gate protected against was closed directly. The store now refuses a plugin whose floor exceeds the running core on all three routes in:

route gated by
install_plugin — every path that re-downloads #431, #433
update_plugin's git branch — pulls in place #508
install_from_url — sideloading #510

A pre-3.2.0 user cannot receive a sunset plugin at all, so they keep the version they already run. Refusal replaced the bundled copy — which is what the copy was standing in for.

Also recorded

What shipped: eight plugins, ~5,800 lines of frozen fallback, as plugins #346/#349/#350/#351. And the two findings worth carrying to the next module:

  • baseball's fallback was the only one holding orchestration logic the core lacked — a scroll_speed reinterpretation running 10–20× faster than configured. Standardised onto the core rather than preserved.
  • Two tests had been leaning on the guard. soccer/test_live_screens.py stubbed src in a way that shadowed the core, so it had been exercising the frozen copy rather than the shipping class since B5.

The remaining-work list is replaced

Its first item was "nothing on the critical path, B6 is waiting on calendar time". What actually remains:

  1. Hardware soaks — with a note to check the rig's *_display_mode first; a board in switch mode will load a sunset plugin happily and tell you nothing about the scroll code the sunset changed.
  2. Cut 3.3.0not required by B6, whose floors are 3.2.0 and 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 now the sunset has closed — game_renderer.py is the largest duplication left (~11,500 lines across eight, with ~36,500 more in the eight sports.py). Note core already ships src/base_classes/sports/ that no plugin imports; check whether it has drifted before treating it as the target.

The pre-B6 sections are kept as history — the reasoning still applies to the next module, it is just no longer in force for this one.
